Methods A total of 32 patients with IIH hospitalized in the Department of Emergency Neurology, Xuanwu Hospital, Capital Medical University from July 2021 to June 2023 were retrospectively enrolled. Baseline data (age, gender, height, BMI, intracranial pressure), clinical manifestations, MRV or DSA and ultrasound examination parameters (internal diameter and blood flow of internal jugular vein, optic nerve sheath diameter, optic disc height, etc.) of patients were collected, and the data were analyzed and summarized. Results ①A total of 32 patients were enrolled in this study, with age of (32.0±10.6) years, male to female ratio of 9∶23, height of (162.0±8.3) cm, BMI of 27.5 (24.0-31.8) kg/m2, and intracranial pressure of 330.0 (300.0-396.3) mmHg (1 mmHg=0.133 kPa). ②The clinical manifestations of the enrolled patients were headache in 16 cases (50.0%), blurred vision in 16 cases (50.0%), nausea and vomiting in 12 cases (37.5%), dizziness in 6 cases (18.8%), tinnitus and intracranial tinnitus in 6 cases (18.8%). ③Among the 32 enrolled patients, 16 cases (50.0%) had diabetes mellitus, 13 cases (40.6%) had hyperlipidemia, 7 cases (21.9%) had hypertension, 4 cases (12.5%) had obstructive sleep apnea syndrome, and 2 cases (6.3%) had spontaneous cerebrospinal fluid leakage. Among the 23 female patients, 5 cases (21.7%) were complicated with polycystic ovary syndrome. ④The diameter of the optic nerve sheath was 4.92 (4.90-5.09) mm, and the height of the optic disc was 0.83 (0-1.28) mm. ⑤According to MRV or DSA results, there were 7 cases (21.9%) of cerebral venous sinus stenosis, including 5 cases (15.6%) of right cerebral venous sinus stenosis and 2 cases (6.3%) of left cerebral venous sinus stenosis. ⑥In the non-stenosis group, the internal diameters of J2 and J3 segments of the right internal jugular vein were larger than those of J2 and J3 segments of the left internal jugular vein [(6.48±1.69) mm vs. (5.63±1.10) mm, P=0.006; (4.62±1.44) mm vs. (3.42±0.88) mm, P＜0.001]. The blood flow in J2 and J3 segments of the right internal jugular vein was greater than that in J2 and J3 segments of the left internal jugular vein [(376.8±172.8) mL/min vs. (229.6±93.3) mL/min, (214.4±104.0) mL/min vs. (115.2±62.9) mL/min, all P＜0.001]. In the cerebral venous sinus stenosis group, the internal diameter of the J3 segment on the narrow side of the internal jugular vein was smaller than that on the healthy side [(3.23±1.05) mm vs. (3.99±1.25) mm, P=0.011]. The blood flow in the J3 segment on the narrow side of the internal jugular vein was lesser than that on the healthy side [(91.4±68.7) mL/min vs. (192.9±87.9) mL/min, P=0.004]. Conclusions The results showed that IIH was closely related to obesity, and was associated with a higher incidence of polycystic ovary syndrome, spontaneous cerebrospinal fluid leakage, obstructive sleep apnea syndrome, hypertension, hyperlipidemia, diabetes mellitus, and cerebral venous sinus stenosis. Meanwhile, the internal diameter and blood flow in the J3 segment on the narrow side of the internal jugular vein were smaller than those on the healthy side. IIH causes a widening of the optic nerve sheath diameter and an increase in the height of the optic disc.

The studies on balancing high-quality basic education development and controlling the increasing housing prices for sustainable development and social equity in big cities have drawn a huge academic attention. Taking Guangzhou's sub-districts as study areas, this research investigates the relationships of spatial distribution between housing prices and the high-quality schools with different grades and stages through examining point of interest (POI) data. The results show that: ① The public fiscal investment, educational reforms, enrollment changes, population numbers, applicant poll, as well as the local history, spatial planning and its functions are key factors that affect the spatial relationships between high-quality schools and housing prices. ② From the perspective of educational stages, high-quality elementary schools contribute the greatest correlation with housing prices, while sequentially the kindergartens, secondary schools and high schools are less related. ③ The general spatial correlation presents a "core-periphery" differentiation between the inner city and the suburban area from high to low in the municipality of Guangzhou; while in sub-districts level, the higher the density of high-quality schools, the more costly the housing it is. ④ There is a strong correlation relationship between the density of high-quality public schools and the high housing prices in city core, and there is a high agglomeration of high-quality private schools in the suburbs, especially the private kindergartens at the municipal level, contributes the greatest correlation with housing prices, while there is no correlation between the high quality schools and housing prices in the outskirts. The research calls for a reform to decrease the strong correlation between the high quality basic education and housing prices through rational planning by locating more better schools to suburban areas to change the imbalance of basic education distribution in Chinese cities.

In order to improve the accuracy of internet intrusion detection methods, an intrusion detection method combining convolution neural network and attention mechanism is proposed. Using Borderline-SMOTE oversampling algorithm and MinMax normalization to preprocess data, effectively alleviate the problem of large differences in the amount of intrusion data, and improve the detection performance of unbalanced data; the convolution neural network inception structure is used for multi-scale feature extraction of data, and the attention mechanism is used for dimension update to improve the accuracy of feature expression when the model processes massive data. The experiment shows that the average accuracy of the intrusion detection method is 99.57%. Compared with SVM, CNN, RNN, and BLS-GMM, the accuracy increases by 4.48%, 1.35%, 1.62% and 0.04% respectively, and the recall increases by 4.48%, 1.36%, 1.62% and 0.14% respectively.

Objective To study the correlation between serum bone turnover markers and FRAX fracture risk score in healthy middle-aged and elderly people, and to explore the value of serum bone turnover markers in fracture risk prediction. Methods The data of age, sex, body mass index (BMI), bone mineral density, and serum bone turnover indexes in 121 healthy middle-aged and elderly people over 50 years old were collected retrospectively, and the FRAX fracture probability was calculated. Patients with FRAX major osteoporotic fracture probability (FRAX-M) ≥20% or FRAX hip fracture probability (FRAX-H) ≥3% were classified as high fracture risk group, and patients with FRAX low-medium fracture risk group were classified as low fracture risk group. The correlation between FRAX fracture probability and serum bone turnover markers was analyzed, and multiple-linear-regression analysis was carried out with FRAX fracture probability as dependent variables. Results Univariate analysis showed that serum levels of osteocalcin (OC) and total type 1 procollagen N-terminal peptide (tP1NP) were higher in the FRAX high-risk group than in the FRAX low-medium risk group (P<0.05). In the correlation analysis, OC and tP1NP were positively correlated with the probability of major osteoporotic fracture in FRAX (r=0.385,0.378, P<0.001), while OC and tP1NP were positively correlated with the probability of hip fracture in FRAX (r = 0.308, 0.287, P < 0.001) . In the multiple linear regression analysis with the probability of FRAX major osteoporotic fracture and hip fracture as dependent variables, PINP remained in the regression equation, and the β= 0.258 (P < 0.001),0.306 (P = 0.001), respectively. Moreover, hierarchical analyses showed a significant increase in the ability of the regression model to predict fracture risk after the addition of tPINP. Conclusion The total type 1 procollagen N- terminal peptide (tP1NP) may be an important factor in the risk of brittle fracture. It is suggested that the value of serum bone turnover marker tP1NP should be considered in clinical fracture risk prediction. [ABSTRACT FROM AUTHOR]

Objective To employ Mendelian randomization (MR) to explore the association between the gut microbiome (GM) and bone mineral density (BMD). Methods GM and BMD GWAS data were selected from the IEU GWAS database at the University of Bristol. Inverse variance weighted (IVW), weighted median estimator (WME), and MR-Egger regression for two- sample MR analysis were used. Odds ratios (ORS) were used to evaluate the causal relationship between GM and BMD. Results The result showed a causal relationship between GM and BMD. Among them, the genera bacteroides, streptococcus, and the families ruminococcaceae UCG002 and ruminococcaceae UCG005 might be protective factors for BMD, while the genera gordonibacter, oxalobacter, and thermoanaerobacter might be potential risk factors for BMD. In addition, there might be unknown gut microbiota that were potential threats to BMD. Conclusion We conducted a comprehensive assessment using Mendelian. randomization to investigate the causal effect of 211 gut microbiota species (from phylum to genus level) on BMD. The result. suggest that bacillus spp., streptococcus lactis, streptococcaceae UCG002, and streptococcaceae UCG005 may serve as protective factors for BMD. On the other hand, gordonella spp. clostridium oxalicum spp., and tethanella spp. may act as potential risk factors for BMD. Additionally, there might be unidentified intestinal flora that poses a potential threat to BMD. These findings support the influence of gut microbiota on BMD and provide valuable insights into specific flora that warrant further investigation. [ABSTRACT FROM AUTHOR]

The negotiation on bilateral investment treaty(BIT)between China and the US was critical for both parties. The deep influence of this negotiation over the innovation of the regime of international investment law, the clarification of the standing points of both two countries, and the up-gradation of China's policy over its investment treaty shall not be underestimated. Under such a background, methodologies of rechtspolitik, hermeneutics and comparative law were employed to study on the dynamics, policy choice for China to upgrade its BIT and a version of such upgraded BIT was discussed and named as the fourth generation Chinese BIT. Certain core provisions of the foresaid fourth generation Chinese BIT was illustrated in detail in the current paper. This study found that:(1)economical, domestic political, and international political considerations are the three main driving powers for China to upgrade its BIT policy. Economically, the accumulation of outbound investment requires China to modify its BIT policy to adapt to its role shift from a net capital importer to a capital importer-exporter. Domestic politically, the target-setting to realize a deepening and comprehensive reform requires China to emphasize the weight of upgrading its BIT as a tool for “promoting reforms by the way of open-door”. For international political consideration, upgrading its BIT can improve China's power in the discourse of rules on international investment governance.(2)China should adopt a balanced and liberal approach in upgrading its BIT. China should improve its regulatory circumstance to facilitate the access of foreign investment while guaranteeing the balance between the rights of the foreign investor and the host states. In the phase of admission of investment, it could adopt the policy of national treatment + negative lists for admission toward foreign investment.(3)Based on the doctrine of balanced and liberal standard, a set of rules of Chinese BIT were proposed. Among which, for fair and equitable treatment(FET)clause, FET clause should be connected to the international minimum standard of customary international law. For expropriation and compensation clause, the fair market value should be set as the standard to calculate the value of compensation while the elements of indirect expropriation should be clarified. For clauses on social responsibilities, the importance of these clauses should be addressed but their stipulation should be carefully drafted to soften the binding force, enforceability and arbitrability of them. For dispute resolution clauses, China should design the clauses on the mechanism of investor-state dispute settlement(ISDS)in detail in its BIT to reduce the flexibility of these clauses. At the same time, for certain disputes, it is better to refrain them from ISDS but to state-state dispute settlement(SSDS)mechanism in less politicalization of such investment disputes. The study on the dynamics, policy choice of upgrading China BIT and detailed analysis over the substantial and procedural clauses of it, reflected the attitude of China toward the innovation over international investment treaty, played a role in negotiating a Sino-US BIT, and provides a reference for improving China's BIT policy and negotiating another BITs with its counterparts.

Objective To investigate the inhibitory effect of metformin on the proliferation and migration of esophageal squamous cell carcinoma, and the regulatory mechanism of the growth ⁃arrest ⁃specific 6 (Gas6) and its ligand Axl. Methods The EC109 and TE ⁃1 cells of esophageal squamous cell carcinoma were treated with different concentrations of metformin. The cell proliferation was measured by the CCK⁃8 assay or the plate clone formation. The migration ability was detected by wound healing and transwell migration assays. Apoptosis was detected by TUNEL assay and the mitochondrial oxidative stress state was detected by Mito⁃SOX. The revealed mitochondrial membrane potential (MMP) was measured by JC⁃1 staining. The expression of Gas6 was detected by immunofluorescence and by the changes of the Gas6/Axl pathway and apoptosis⁃related proteins were analyzed using Western blot. In addition, after treatment with Axl inhibitor (bemcentinib, R428), the effect of metformin on the proliferation, migration of EC109 cells, and subcutaneous tumor formation in nude mice were observed. Results Metformin significantly decreased the cell viability of EC109 and TE⁃1 cells compared to the control group ( PEC109<0.001; PTE⁃1<0.001), while the effect was not significant on the activity of Het⁃1A cells (P=0.380). Metformin inhibited the colony formation (P=0.002) and migration (P<0.001) of EC109 cells, and increased the apoptosis rate (P=0.002), inducing a dose ⁃dependent increase in mitochondrial reactive oxygen species (P<0.001) and decreasing MMP levels (P<0.001). Furthermore, Metformin reduced Gas6 fluorescence intensity in EC109 cells, blocked Gas6 expression in EC109 and TE⁃1 cells, down⁃regulated the levels of p⁃Axl, Axl and Bcl2 in EC109 cells, and increased the activities of Bax, cytochrome C and Caspase3 in EC109 cells. In addition, compared with metformin alone, metformin combined with R428 demonstrated superior efficacy in inhibiting tumor growth, migration and subcutaneous tumor formation in nude mice. Conclusions Metformin can regulate mitochondrial homeostasis, activate an oxidative stress⁃induced apoptotic response, and exert anti⁃proliferative and anti⁃migrative effects on EC109 cells, which may be associated with the down⁃regulation of Gas6/Axl signaling pathway.

Objective To analyze the factors affecting the bowel preparation effect of polyethylene glycol electrolyte powder (PEG-ELP) combined with dimethicone in hospitalized patients. Methods Clinical data of bowel preparation of 200 hospitalized patients who underwent colonoscopy were retrospectively analyzed. The influencing factors of bowel cleaning effect were analyzed. Results Univariate analysis showed that hypertension， dyslipidemia， positive urine ketone body， and colonoscopy scheduled in the afternoon were influencing factors of the cleanliness of bowel preparation， respectively （all P < 0.05). Multivariate regression analysis indicated that dyslipidemia (OR = 2.312， 95%CI (1.245，4.293)，P = 0.008)， hypertension （OR = 2.270， 95%CI (1.193，4.318)， P = 0.013)， and colonoscopy scheduled in the afternoon (OR = 2.377， 95%CI (1.279，4.416)，P = 0.006） were the risk factors for low quality of bowel preparation， respectively. Conclusion For hospitalized patients receiving bowel preparation with PEG-ELP combined with dimethicone， hypertension， dyslipidemia and colonoscopy scheduled in the afternoon are the independent risk factors affecting bowel preparation before colonoscopy.

Atherosclerosis is a complicated pathophysiological process characterized by the accumulation of atheromatous plaque in the arterial wall and subsequent narrowing of the arteries, and it is one of the major causes of the high mortality and disability in cardiovascular disease. The initiation and progression of atherosclerosis is a chronic degenerative process with complicated mechanisms involving multiple cells and molecules. Oxidative stress, a series of adaptive responses caused by the imbalance between reactive oxygen species and antioxidant system, is considered as one of the crucial mechanisms in the development of atherosclerosis. This review presents the relationship between oxidative stress and atherosclerosis from the perspective of the different sources of reactive oxygen species in the organism, summarizes the effects of oxidative stress on different cells, biomolecules and biological processes in atherosclerosis, and briefly describes the clinical research and applications of antioxidant agents in the treatment of atherosclerosis.
