BACKGROUND:The aim of present study is to demonstrate that volatile oil of flos magnoliae biondii pamp(VOMbp) possess anti-immunology inflammatory property.OBJECTIVE:To explore the effect of VOMbp on adjuvant arthritis in rats.DESIGN:Grade sampling,randomized controlled quantitative analysis.SETTING:Teaching and Researching Department of Pharmacology,Chengdu University of Traditional Chinese Medicine.MATERIALS:This study was carried out at the Teaching and Researching Department of Pharmacology,Chengdu University of Traditional Chinese Medicine from December to April in 1999. Totally 120 Wistar rats were involved.METHODS :Wistar rats were randomly divided into 4 groups :model control group, 0.28 mL/kg and 0.14 mL/kg VOMbp group,and 25 mg/kg dex-amethasone group. Allergy were induced in all rats through intra-cutaneous injection of Freund's adjuvant (0.1 mL/rat)at metatarsus so as to establish multiple arthritis model in rat. According to different dosage,the experiments were carried out in three batches with 10 rats in each group.Rats in the first batch were given VOMbp three days before inducing allergy for consecutwe 3 days,in order to observe the influence of VOMbp on adjuvant induced acute non-specific inflammatory;Rats in the second batch were given VOMbp on the 8th day sensitization allergy for consecutive 7days so as to explore the protective effect on secondary pathological changes;rats in the third batch were administratedon the 19th day after sensitization for consecutive 7 days for study in therapeutic effect on sec ondary pathological changes. Meanwhile foot tumefaction and the level of prostaglandin E2in ankle arthritis were observed.MAIN OUTCOME MEASURES: ① Effect of VOMbp on the adjuvant induced acute non-specific inflammatory. ② Preventive effect on adjuvant arthritis. ③ Therapeutic effect on adjuvant arthritis.RESULTS :① VOMbp could significantly suppress the primary foot tume faction. ②Moreover VOMbp of preventive dosage could most significantly suppress the secondary arthritis tumefaction [(0.231±0.065)mL of 0.28 mL/kg group and ( 0.206±0.082 ) mL of 0.14 mL/kg group] ,accompanied by PG-E2 decrement in tumefaction tissues [(0.133 2±0.057 2), (0.138 5 ±0.042 6)OD278nm correspondingly].③ No obvious effect of VOMbp of therapeutic dosage on secondary inflammatory tumefatcion of arthritis could be observed in 0.14 mL/kg group,but obvious decrement of prostaglandin E2 could be observed in edema tissue;While 0.28 mL/kg VOMbp exerted most significant or significant influence on above parameters. CONCLUSION:VOMbp possess inhibiting effect on Freund's adjuvant induced primary foot tumefaction and secondary arthritis,with the preventive effect better than therapeutic effects.The therapeutic effect was proved better in higher dosage group.

Objective:
To examine the association between neonatal birth weight and maternal type 2 diabetes (T2DM), so as to provide insights into the formulation of the early T2DM prevention and improvements of maternal and children health.
Methods:
Single-nucleotide polymorphisms (SNPs) were collected from two genome-wide association studies (GWAS) that examined the association between neonatal birth weight and maternal T2DM. Inverse variance weighted method was employed for forward Mendelian randomization with 26 birth weight-associated SNPs as instrumental variables and maternal T2DM as the study outcome and for reverse Mendelian randomization with 18 maternal T2DM-associated SNPs as instrumental variables and maternal effects of neonatal birth weight as the study outcome. The heterogeneity was examined using Cochran's Q test, and the pleiotropy was evaluated using MR-Egger regression, while the robustness of the results was evaluated using leave-one-out test.
Results:
Cochran's Q test detected heterogeneity across two studies (P=0.019, 0.038), and random effect models were employed. Mendelian randomization showed that an increase in neonatal birth weight by per standard error (approximately 488 g) resulted a 29.9% reduction in the risk of maternal T2DM (OR=0.701, 95%CI: 0.547-0.899), and maternal T2DM increased the neonatal birth weight by 0.074 standard errors (OR=1.074, 95%CI: 1.043-1.106). No horizontal pleiotropy was seen for instrumental variables (P=0.241, 0.188). With each SNP excluded in turn, the results of Mendelian randomization study were robust.
Conclusion
There are bidirectional associations between neonatal birth weight and risk of maternal T2DM.

A polyphenolic compound, 1,2,4,6-tetra-O-galloyl-β-D-glucose (1246TGG), was isolated from the traditional Chinese medicine Phyllanthus emblica L. (Euphorbiaceae) and assayed for its potential as an anti-hepatitis B virus (HBV) agent. The cytotoxicity of 1246TGG on HepG2.2.15 as well as HepG2 cells was determined by observing cytopathic effects, and the effects of 1246TGG on secretion of HBsAg and HBeAg in HepG2.2.15 cells were assayed by enzyme immunoassay. Results indicates that treatment with 1246TGG (6.25 μg/mL, 3.13 μg/mL), reduced both HBsAg and HBeAg levels in culture supernatant, yet the inhibitory effects tend to decline with the assay time. This study provides a basis for further investigation of the anti-HBV activity and possible mechanism of action of 1246TGG.

Objective To evaluate the method of vulvar reconstruction after extended vulvectomy. Methods Retrospectively, fourteen cases of vulva carcinoma were treated by radical wide local excision, and the defects were repaired with anterolateral thigh flap and inferior pedicle rectus abdominal myocutaneous flap. After the flap was harvested, it was put on the defect through the tunnel between the donor and the recipient site and the vulvae was reconstructed. Results All the flaps were survived except 1 anterolateral thigh flap with partial necrosis. One patient was infected at the groin incision but the flap and the grafted skin were survived. The patients were treated with change of the dressing and recovered after skin grafting. All other incisions were healed with first intention. The partial necrosis area was about 4 cm?6 cm, it healed at 36 postoperative days after free skin grafting. The reconstructed vulvae were plump and elastic. It appeared like the normal vulvae and there was no contraction of the vagina. Conclusions Vulvar reconstruction with the anterolateral thigh flap and rectus abdominal flaps after the radical vulvectomy could make the patients recover easily. It produces almost normal appearance and function of the vulvae, reduces the time of would healing. The patient could have the next therapy more quickly and the quality of life improves. It has wide application value in clinics.
