A girl patient, seven years old, complaining intermittent periumbilical pain accompanied with headache and vomiting for almost one year. Acupuncture was adopted in treatment. Acupoints were Băihuì(百会GV20), Yìntáng (印堂EX-HN3), Zhōngwăn (中脘CV12), Tàiyáng (太阳EX-HN5), Wángŭ (完骨GB12), Hégŭ (合谷LI4), Tiānshū (天枢ST25), Zúsānlĭ (足三里ST36), Sānyīnjiāo (三阴交SP6) and Tàichōng (太冲LR3), electroacupuncture, warming needling moxibustion and infrared irradiation were applied. Acupuncture and moxibustion were given once every two days and 10 treatments were as one course. After one course of treatment, the child patient narrated that the attack frequency of headache and abdominal pain was reduced, the severity alleviated and the persistent duration shortened. After two courses of treatment, abdominal pain never occurred and the child patient was recovered and had a normal life and school activity. The disease was not recurred in one-year follow-up.

F-box and WD repeat domain containing 10 (FBXW10) is a member of the FBXW subgroup that contains the WD40 domain. FBXW10 has been rarely reported in colorectal cancer (CRC) and its mechanism is unclear. To investigate the role of FBXW10 in CRC, we conducted in vitro and in vivo experiments. Through the database and our clinical samples, we found that FBXW10 expression was up-regulated in CRC, and it was positively correlated with CD31 expression. CRC patients with high FBXW10 expression levels had a poor prognosis. Overexpression of FBXW10 up-regulated cell proliferation, migration and vascular formation, while knockdown of FBXW10 had the opposite effects. Studies on the mechanism of FBXW10 in CRC showed that FBXW10 could ubiquitinate large tumor suppressor kinase 2 (LATS2) and promote its degradation with the Fbox region of FBXW10 played an essential role in this process. In vivo studies demonstrated that knockout of FBXW10 inhibited tumor proliferation and reduced liver metastasis. In conclusion, our study proved that FBXW10 was significantly overexpressed in CRC and was involved in the pathogenesis of CRC by affecting angiogenesis and liver metastasis. Mechanistically, FBXW10 degraded LATS2 through ubiquitination. Therefore, FBXW10-LATS2 can be used as a therapeutic target for CRC in subsequent studies. [Display omitted] [ABSTRACT FROM AUTHOR]

Background The uncontrolled inflammatory response following infection is closely related to the morbidity and mortality of neonates. Interleukin 6 (IL-6) plays an important role in the pathogenesis and prognosis of this process. To better elucidate the secretion of IL-6 following infection in neonates, we investigated the IL-6 level and mechanism of IL-6/TLR4 signaling pathways. Methods We compared the IL-6, procalcitonin (PCT), and CRP levels between septic neonates and toddlers. In vitro cord blood samples from healthy term neonates and peripheral venous blood from healthy adult volunteers were collected. Protein expression was analyzed by Western blotting, mRNA expression by real-time PCR and membrane molecule expression by flow cytometry. Results The IL-6 concentrations were significantly higher in the neonate group than in the toddler group (p < 0.05). In the toddler group, the IL-6 concentrations were correlated positively with both PCT and CRP (PCT: r = 0.451, p = 0.001; CRP: r = 0.243, p = 0.023). In vitro, the secretion of IL-6 increased with the rising concentrations of LPS; at 1000 ng/ml LPS, IL-6 secretion from the monocytes of neonates was significantly higher than that of adults. There was a marked decreased level of MyD88 in neonate monocytes compared with that in adult monocytes. Additionally, the mRNA levels of Zc3h12a in neonate monocytes were significantly lower than those in adult monocytes following LPS stimulation. Conclusion Neonates displayed enhanced IL-6 production after infection. Our study, for the first time, reported a significant decrease in the expression of Zc3h12a in neonates. Thus, Zc3h12a may be a key factor for the aberrant increase in IL-6 after neonate infection. [ABSTRACT FROM AUTHOR]

Abstract: Isovaleric acidemia (IVA) is a rare inherited metabolic disease caused by a deficiency in isovaleryl-CoA dehydrogenase (IVD). Newborn screening with tandem mass spectrometry leads to early identification of individuals with risk of IVA. The family specific mutations are useful for prenatal diagnosis. Molecular genetic analysis helps to further confirm the clinical diagnosis of IVA. We describe here the clinical and metabolic features of a Chinese infant with early onset IVA. Sequence analysis of the IVD gene identifies compound heterozygous mutations in this patient, c.39G>A (p.W13X) nonsense mutation and c.597C>G (p.I199M) missense mutation, both of which are previously unreported. Structural analyses suggest that the p.I199M missense mutation may destabilize the IVD monomer structure and affect the interaction between IVD and flavin adenine dinucleotide. Both the clinical and genetic features of this patient help to further expand our knowledge of IVA. [Copyright &y& Elsevier]

Abstract: Novozyme435 facilitated kinetic resolution of 2-heptylamine was here presented. Methyl methoxyacetate was used as acyl donor. A survey of influencing factors including hydrogen bonding effect, solvent effect, steric effect, temperature and the amount of acyl donor were investigated in detail. At the optimum conditions, the enantiomeric separation was successfully obtained within 8h at 20°C, and gave high conversion and optical purity of (R)-2-heptylamine, 48.9% and over 99% respectively. The immobilized lipase B was found to be suitable for the enantiomeric separation of aliphatic amines with good recyclability. [Copyright &y& Elsevier]

Let Ω be a finite dimensional central algebra with an involutorial antiautomorphism σ and char Ω≠2, Ωn×n be the set of all n×n matrices over Ω. A=(aij)∈Ωn×n is called bisymmetric if aij=an−i+1,n−j+1=σ(aji) and biskewsymmetric if aij=−an−i+1,n−j+1=−σ(aji). The following systems of generalized Sylvester equations over Ω[λ]:A1X−YB1=C1,(I)&z.tdfnc;AsX−YBs=Cs,A1XB1−C1XD1=E1,(II)&z.tdfnc;AsXBs−CsXDs=Es,are considered. Necessary and sufficient conditions are given for the existence of constant solutions with bi(skew)symmetric constrains to (I) and (II). As a particular case, auxiliary results dealing with the system of Sylvester equations are also presented. [Copyright &y& Elsevier]

A new reaction system for biodiesel production by the base-catalyzed transesterification process has been developed. Bentonite is used as a water adsorbent in the traditional homogeneous base-catalyzed transesterification reaction system to create a heterogeneous system that improves the reaction efficiency. The influence of bentonite on the NaOH-catalyzed methanolysis of soybean oil and the accompanying reaction mechanisms were investigated. It was found that an appropriate introduction of bentonite can promote the methanolysis. By the rapidly removal of the water from the system, bentonite enhances the transformation of NaOH to the catalytically active methoxide species. Further, the main side reactions are significantly inhibited. The methanolysis of triglycerides took place in the liquid phase rather than in the solid phase. The introduction of bentonite also lowered the soap concentration in crude biodiesel, which was beneficial for the post-treatment to generate refined biodiesel. [ABSTRACT FROM AUTHOR]
