Fault slip rates are critical to quantify continental deformation. Those along the Karakax fault (northwestern Altyn Tagh Fault: ATF) have been debated, even though it is one of Tibet's most outstanding active faults. At Taersa, using LiDAR measurements of terrace and fan riser offsets (∼6 to ∼500 m) and 10Be/26Al dating of alluvial surfaces (<210 ka), we obtain a late Quaternary slip rate of ∼2.5 ± 0.5 mm/yr. This doubles the ∼2.6 ± 0.5 mm/yr rate time span found to the east and west. We interpret the ∼150 km‐long, free‐faced rupture along the fault to be that of the M ∼ 7.6 event felt in Hotan in 1882. Characteristic slip (∼6 m) during four large earthquakes since ∼10 ka implies a ∼2500 ± 500 years return time. A ∼3 mm/yr rate is consistent with the ∼80 km offset of the Karakax river since uplift of the West Kunlun range and sediment deposition in the Tarim foreland accelerated, ∼24 Ma ago. The faster slip rate (∼10.5 mm/yr) on the central ATF matches the sum of those along the reactivated West Tibetan terrane boundaries (Karakax and Longmu‐Gozha Co faults) at the Uzatagh triple junction (∼36°N, 83°E). The abrupt termination and altitude drop of the Karakorum range where the Longmu Co and Karakorum faults meet (Angmong junction), also reflect triple junction kinematics. Such localized changes account for the rise of the Karakorum and West Kunlun ranges and support lithospheric block tectonics rather than diffusely distributed deformation. Plain Language Summary: How the Tibetan plateau rose to ∼4500 m and deforms today remain outstanding questions. Tibet's northern edge follows the ∼2000 km‐long ATF, whose westernmost branch is the Karakax fault. Despite the spectacular escarpments and offsets observed along that fault, its slip rate, critical to quantify continental deformation, has remained controversial. Here, we corroborate that, for the last ∼210,000 years, that rate has been ∼2.5 ± 0.5 mm/yr, based on high‐resolution topography and dating of left‐laterally offset fluvial surfaces. The ∼80 km offset of the Karakax river implies that this rate may have remained constant since the rise of the Kunlun range above the Tarim basin started ∼24 Ma ago. The sharp fault trace reflects the exceptional preservation, since ∼10,000 years ago, of four M ∼ 7.6 earthquake ruptures (the last in 1882), each with ∼6 m of slip (∼2500 years return time). Fault slip rates, GPS vectors and mountain altitudes across western Tibet reflect block motions and triple junction kinematics rather than continuum deformation. Specifically, localized velocity changes appear to account for the rise of the West Kunlun and Karakorum ranges. Our results bridge the gaps between present and long‐term geological history, and broad‐scale geodesy and local field evidence. Key Points: The ∼400 km‐long, left‐lateral Karakax fault (western Altyn Tagh fault) slip rate has been ∼2.5 ± 0.5 mm/yr for ∼210 kaFour M ∼ 7.6 earthquakes (150 km rupture length; 2.5 ka return time) have offset Holocene terraces (6, 12, 18, and 24 m characteristic slip)Block tectonics and triple junction kinematics account for 24 Ma deformation of west Tibet and rise of ≥8000 m‐high Karakorum range [ABSTRACT FROM AUTHOR]

Cosmetics have a long history in China, but their origins remain unclear. Cosmetic industry potentially originated in the Spring and Autumn Period (770–476 bce), but little is known about the early manufacture and use of cosmetics. The Liujiawa site, located on the southern edge of the Loess Plateau in northern China, was the late capital of the ancient Rui state in the early to mid‐Spring and Autumn Period. During the excavation, a sealed small and exquisite container with suspected cosmetic use was unearthed from tomb M49 belonging to a male associated with the aristocratic class. We report in this paper the multidisciplinary application of ATR‐FTIR, XRD, SEM, stable isotope analysis, GC‐MS and GC‐C‐IRMS analysis of the residue inside the container, demonstrating that the residue, which was made of ruminant adipose fat mixed with monohydrocalcite from cave moonmilk, was likely used as cosmetic face cream by the nobleman of the Rui state. This study provides an early example of cosmetic production in China, and, together with the prevalence of similar cosmetic containers during this period, it suggests the rise of an incipient cosmetics industry. Furthermore, the exploitation of moonmilk, a special stalactite in some limestone caves, reflects the link between early Taoist School and cosmetic production encouraged by the aristocratic class.

Abstract: Aim: To investigate whether peer support would reduce diabetes distress and improve glycaemic control when added to usual diabetes education among adults with Type 2 diabetes in China. Methods: We conducted a cluster randomized trial involving 400 adults with Type 2 diabetes from eight communities in Nanjing. All participants received usual education for an average of 2 h each month from physicians, certified diabetes educators, dieticians, psychologists and podiatric nurses. Peer support was led by trained peer leaders and included diabetes knowledge‐ and skills‐sharing at least once a month, as well as peer‐to‐peer communication. The primary outcome was diabetes distress measured using the Diabetes Distress Scale at 12 months. Secondary outcomes included fasting plasma glucose, 2‐h postprandial glucose and HbA
1c concentration. Outcome data were collected from all participants at baseline, 6 months and 12 months. Results: From 2012 to 2013, there were 200 participants in each study arm at baseline. Compared with the usual education arm, the peer support with usual education arm had greater reductions in regimen‐related distress (1.4 ± 0.6 vs 1.2 ± 0.4;P =0.004) and total distress (1.3 ± 0.4 vs 1.2 ± 0.3;P =0.038) at 6 months. At 12 months, the scores for emotional burden (1.2 ± 0.3 vs 1.4 ± 0.6;P =0.002), physician‐related distress (1.1 ± 0.3 vs 1.3 ± 0.4;P =0.001) and total scores (1.2 ± 0.3 vs 1.3 ± 0.4;P =0.002) were significantly lower in the peer support with usual education arm than in the usual education arm. Fasting plasma glucose levels were lower in the peer support with usual education arm than in the usual education arm at 6 months (7.5 ± 1.95 vs 8.0 ± 2.2;P =0.044) and 12 months (7.0 ± 2.3 vs 7.6 ± 1.5;P =0.008). Conclusions: Beyond the benefits of usual education, peer support was effective in reducing diabetes distress for Type 2 diabetes mellitus.

A human skull, buried about 2500 years ago in a Bronze Age cemetery at Jinggouzi, a site of an important ethnic group in ancient China, appeared to have characteristics of fibrous dysplasia. The CT images indicated a reduction in bone density and relatively homogeneous lesions. More features were revealed using CT reconstruction techniques. Lesions seen in low‐magnification images using a 3D deep‐field microscope had an irregular honeycomb‐like structure. At higher magnification, the trabeculae morphology and the gaps between the trabeculae were irregular and varied in size and shape. Paraffin‐embedded specimens stained with HE showed trabeculae with tortuous irregular arrangements varying in shape and width. The irregular trabeculae of woven bone has been described as having fibrous dysplasia. Molecular analysis of the GNAS gene indicated no mutation. This provides a non‐invasive approach for us to make more comprehensive diagnoses and to assist research into ancient human diseases. [ABSTRACT FROM AUTHOR]

Objective Our aim is to evaluate the expression of SATB1 in human oral squamous cell carcinomas ( OSCC) and its role in the invasiveness and metastasis of OSCC. Subjects and methods A human OSCC tissue microarray was used to evaluate the expression pattern of SATB1. SATB1 mRNA knockdown was performed in human OSCC cell lines SCC25 and Cal27 to assess the function of SATB1 in the invasiveness and metastasis of OSCC. Results SATB1 is highly expressed in human OSCC determined by immunohistochemistry, and its nuclear/cytoplasmic ratio of histoscore is significantly correlated with patients' prognosis. Reduced cell motility, invasiveness, expression of epithelial to mesenchymal transition ( EMT) markers (N-cadherin and β-catenin), and elevated expression of epithelial markers were observed in SATB1-knockdown cells in in vitro studies. Depletion of SATB1 also restored a cobblestone-like morphology in TGF-β1-treated cells. Conclusions These findings suggest SATB1 may play an important role in OSCC invasiveness and metastasis.

To address severe grassland degradation, the Chinese government implemented national restoration programmes, which in turn drove a research focus towards assessment of the environmental effectiveness of such initiatives. In this study, net primary productivity ( NPP) was used as an indicator for assessing the impacts of land use and cover change ( LUCC), improved land-use management and climate change on the grassland ecosystem of the Shiyanghe River Basin. NPP was calculated on the basis of the Carnegie- Ames- Stanford Approach model, which is driven by a Moderate Resolution Imaging Spectroradiometer ( MODIS) normalized difference vegetation index and meteorological data. The LUCC data for 2001 and 2009 were derived from MODIS land-cover data. During the study period, the net increase in grassland development was 5105·5 km
2 , with 80·4% of the newly developed grasslands attributed to desert-to-grassland conversion. The total NPP of grasslands in 2009 increased by 659·62 Gg C compared with that in 2001. The contributions of human activity and climate change to total NPP increase were 133 and −33% respectively. Land conversion and improved management measures directly increased grassland NPP. These factors are dominant positive driving forces, whereas warm and dry climates impose adverse effects on grassland restoration in the study site. [ABSTRACT FROM AUTHOR]- Published

The central inversion zone in the Xihu Depression, East China Sea, was formed during the Late Miocene. The entire Tertiary succession, nearly 10,000 m thick, has undergone inversion here. The succession is composed mainly of sandstones and mudstones with minor coals and non-marine limestones. Hydrocarbons are present in a series of structural traps which formed as a result of inversion-related deformation. Oil and gas exploration in the Xihu Depressions has demonstrated that at least 90% of the commercial reserves so far found occur in inversion-related structural traps in the central inversion zone, mainly in Eocene (Pinghu Formation) and Oligocene (Huagang Formation) sandstone reservoirs. Previous studies have shown that structural traps are controlled by the intensity and style of inversion tectonics. However, the relationship between the geometry, kinematics and size of the inversion structures and the oil and gas accumulations is not well understood. In this paper, the factors controlling trap formation (and hydrocarbon acumulations) in the study area are considered. Data came from 2D reflection seismic and electic logs from a number of wells. Controlling factors include inversion fault activity rate, inversion rate and the thickness of sediments eroded as a result of inversion-related uplift of the Tertiary succession. The results show that the best exploration targets are located in the southern part of the central inversion zone. This area has a relatively low inversion fault activity rate (average 3.0 m/Ma) and a low inversion rate (average 0.4); a relatively small thickness of sediments was eroded from the Miocene Longjing and Liulang Formations (< 400 m) and the Eocene Pinghu Formation. By contrast, the northern part of the central inversion zone has a relatively high inversion fault activity rate (average 6.8 m/Ma) and a high inversion rate (0.8), and greater thicknesses of sediments were erosively removed (up to 1600 m). This may have resulted in the less favourable preservation of traps and the large-scale leakage of oil and gas. Most oil and gas accumulations occur in the southern part of the central inversion zone, especially in reservoirs in the Longjing, Liulang and Pinghu Formations. [ABSTRACT FROM AUTHOR]

Two experiments were conducted to study the effect of supplemental 100 g/day of live Bacillus cultures (2 × 10
11 cell of Bacillus subtilis and Bacillus licheniformis) on rumen fermentation as well as milk yield and composition in Chinese Holstein cows. In experiment 1, investigating 3 × 10 cows, milk yield and milk protein were increased by using B. licheniformis (p < 0.05) in comparison with an unsupplemented group and the B. subtilis group. Body weight was not significantly affected by Bacillus culture supplementation (p > 0.05). Percentage of milk fat and lactose was not significantly different between treatments (p > 0.05). But milk protein increased with B. licheniformis supplementation (p < 0.05). In experiment 2, carried out with three non-lactating ruminally and duodenally fistulated cows, results showed that B. licheniformis supplementation increased microbial crude protein flow into duodenum (p < 0.05) and decreased the ammonia nitrogen concentration in ruminal fluid at 0.5 h, 1 h, 3 h, 6 h after morning feeding (p < 0.05). Bacillus licheniformis supplementation increased total VFA and acetate concentration in ruminal fluid at 0.5 h, 1 h, 3 h, 6 h after morning feeding (p < 0.05). Bacillus subtilis had no significant effect on rumen fermentation characteristics, duodenal microbial N flow and ruminal apparent nutrient digestibility (p > 0.05). Bacillus licheniformis increased ruminal apparent nutrient digestibility of neutral detergent fibre, acid detergent fibre, and organic matter (p < 0.05). [ABSTRACT FROM AUTHOR]- Published

HLA histocompatibility antigens ,CARBAMAZEPINE - Abstract
To identify HLA-B*15 subtypes distribution in Han population in Beijing, People’s Republic of China, 826 unrelated healthy individuals were typed using the polymerase chain reaction-sequence-based typing method. Within the 246 HLA-B*15 positive individuals, 29 HLA-B*15 alleles were identified, the most predominant of which is B*1501 (40.07%), followed by B*1502 (12.87%), B*1511 (12.87%), B*1518 (9.19%) and B*1532 (3.31%). The distribution of HLA-B*15 subtype frequencies was compared between the Beijing Han, eight other Chinese ethnic minorities and six Chinese populations covering the mainland of China, Taiwan, Hong Kong and Singapore. A neighbor-joining phylogenetic tree was constructed and revealed that the Beijing Han population clustered into the northern populations group and had a closer relationship with northern Han and Hui than with southern Han or other ethnic minorities. These results thus provide useful information that can be used in anthropology, selection for bone marrow transplantation as well as in disease-association study, such as in carbamazepine (CBZ)-induced Stevens–Johnson syndrome and toxic epidermal necrolysis.

- Abstract
Thiamine-responsive megaloblastic anemia syndrome (TRMA) is an autosomal recessive disorder, inherited by the defective SLC19A2 gene that encodes a high-affinity thiamine transporter (THTR-1). TRMA is characterized by the occurrence of classical triad manifestations including megaloblastic anemia, diabetes mellitus, and sensorineural deafness. In addition to the systemic manifestations, ophthalmic features can be present and include retinitis pigmentosa, optic atrophy, cone-rod dystrophy, maculopathy, and Leber congenital amaurosis. Here we report a 6-year-old boy presenting severe early-onset retinal dystrophy with the initial diagnosis of Leber congenital amaurosis, which followed for 12 years. Diabetes mellitus occurred 3 years after vision problem. Eosinophilic granuloma of the left scapula was confirmed at 13 years old. Whole-exome sequencing was performed to identify two novel compound heterozygous variants c.725dupC (p.Ala243Serfs*3) and c.121G>A (p.Gly41Ser) in SLC19A2 gene (NM_006996.3). Oral thiamine supplementation treatment was initiated at 13 years. This case demonstrates Leber congenital amaurosis can present as the first clinical feature before systemic manifestations. Phenotypic variety should be aware and multidisciplinary teamwork and regular follow-up are important for TRMA patient care., (© 2021 Wiley Periodicals LLC.)

- Abstract
Purpose: To estimate the prevalence, causes and risk factors of bilateral visual impairment in rural areas of Tianjin, China., Methods: A large population-based, cross-sectional study. A stratified random cluster sampling method was used to investigate 12 233 participants in all age groups living in rural Tianjin. Participants completed questionnaires and received professional ophthalmology examinations., Results: According to World Health Organization best-corrected visual acuity (BCVA) criteria, the crude prevalence of bilateral visual impairment (BCVA < 20/63), bilateral low vision (BCVA < 20/63 to ≥20/400) and bilateral blindness (BCVA < 20/400) was 2.53%, 2.40% and 0.14% (age- and gender-standardized prevalence was 1.86%, 1.76% and 0.11%). The prevalence increased with age and was higher in women than men. The most common causes of bilateral visual impairment in the total population were cataract (48.39%), refractive error/amblyopia (17.74%), age-related macular degeneration (AMD) (10.00%), diabetic retinopathy (5.81%) and glaucoma (3.87%). For participants younger than 50 years, refractive error/amblyopia was the leading cause of low vision and blindness, while cataract was the major cause in the participants over 50. Female gender, older age and self-reported diabetes were associated with increased risks of visual impairment., Conclusion: The age- and gender-standardized prevalence of low vision, especially in the older group (50+), was higher in this study compared with previous studies in China. Refractive error/amblyopia was the leading cause of bilateral visual impairment in younger group, while cataract was the primary cause in the older group. These findings will provide useful information for planning comprehensive eye healthcare programmes in China., (© 2020 Acta Ophthalmologica Scandinavica Foundation.

- Abstract
Background: Epidemiological data of coeliac disease are lacking from the central Asian region., Aims: To verify the occurrence of coeliac disease amongst four major ethnic groups of Xinjiang Uyghur Autonomus Region, China., Methods: 2277 in-patients with gastrointestinal symptoms (1391 Han, 608 Uyghur, 146 Kazakh and 132 Hui; mean age: 54 ± 12.8 years) were included. Total IgA, anti-deamidated gliadin peptide (DGP)-IgG, and anti-tissue transglutaminase (anti-tTG)-IgA were analysed. All antibody-positive subjects were further tested for endomysial (EMA) antibodies and were HLA genotyped. All subjects with antibody positivity were asked to undergo intestinal biopsy. In addition, a subset of antibody-negative subjects were tested for HLA-DQA1and DQB1., Results: Among the 2277 subjects, 29 subjects were defined as coeliac disease autoimmune (positive results for anti-tTG IgA and EMA-IgA) (1.27%; 95% confidence interval, 0.81%-1.73%), eight of them underwent biopsy and all showed coeliac disease histology (0.35%; 95% Cl, 0.11%-0.59%). The frequency of coeliac disease autoimmunity was lowest among the Han (0.79%), followed by the Uyghur (1.81%), the Kazakh (2.05%) and the Hui (3.03%). The frequency of the HLA-DQ2 and/or DQ8 haplotype was highest in the Uyghur (52.1%), followed by the Hui (44.4%), the Kazakh (40.0%) and the Han (39.4%). Besides, a three times higher frequency of coeliac disease autoimmunity was found among rural living subjects with significantly higher wheat consumption compared to urban living subjects (3.16% vs 0.97%, P < 0.01)., Conclusions: In Xinjiang, coeliac disease does occur, especially in the rural area. The HLA haplotype and environment play key roles in the development of coeliac disease., (© 2020 John Wiley & Sons Ltd.)

- Abstract
Background & Aims: The potential interaction between family history of liver cancer and HBV infection on liver cancer has not been fully examined., Methods: We conducted a population-based case-control study composed of 2011 liver cancer cases and 7933 controls in Jiangsu province, China from 2003 to 2010. Data on major risk or protective factors were collected and HBV/HCV sero-markers were assayed using blood samples. Semi-Bayes (SB) adjustments were applied to provide posterior estimates., Results: Both family history of liver cancer (adjusted odds ratios [OR]: 4.32, 95% confidence intervals [CI]: 3.25-5.73) and hepatitis B surface antigen (HBsAg) positivity (adjusted OR: 9.94, 95% CI: 8.33-11.87) were strongly associated with liver cancer development. For individuals with different combinations of serological markers, the adjusted ORs were 8.45 (95% CI: 5.16-13.82) for HBsAg- and HBcAb-positive; 7.57 (95% CI: 4.87-11.77) for HBsAg-, HBeAg- and HBcAb-positive; and 3.62 (95% CI: 2.47-5.31) for HBsAg-, HBeAb- and HBcAb-positive, compared to all negatives in HBV serological markers. One log increase in HBV DNA level was associated with 17% increased risk (adjusted OR: 1.17, 95% CI: 1.03-1.32). The SB-adjusted OR of HBV-positive individuals with family history of liver cancer was 41.34 (95% posterior interval [PI]: 23.69-72.12) compared with those HBV-negative without family history. Relative excess risk due to additive interaction, the attributable proportion and synergy index were 73.13, 0.87 and 8.04 respectively. Adjusted ratio of OR for multiplicative interaction was 2.84 (95% CI: 1.41-5.75)., Conclusions: Super-additive and super-multiplicative interactions may exist between family history of liver cancer and HBV infection on the development of liver cancer., (© 2019 John Wiley & Sons A/S.
