Anti-müllerian hormone (AMH) is mainly produced by the granulose cells of the developing preantral and antral follicles in women and a reliable marker of the reproductive function of women.The mean terminal t1/2 of AMH is calculated as (27.6 ± 0.8) h.Serum concentration of AMH declines by 5.6％ per year and several reproductive and lifestyle factors are associated with age-specific AMH levels.AMH can be applied to predict the precise age of the menopause and is a marker of ovarian reserve in women of 25 year old and older.Iu the field of assisted reproductive technologies,AMH is beneficial in the individualization of stimulation protocols at controlled ovarian hyperstimulation and may be positively associated with clinical pregnancy rates,live-birth rates and twin gestation after assisted reproduction.The researches of AMH may be helpful in the studies of mechanism of polycystic ovary syndrome (PCOS).AMH measurement may be included as a diagnostic criterion of PCOS and a useful predictive marker for the efficiency of the treatment of PCOS.AMH has been also shown to inhibit tumor growth in vitro and in vivo and can be used as a tumor marker in granulosa cell tumors.By using AMH,ovarian reserve damages caused by different kinds of diseases and treatments,including rheumatoid arthritis,laparoscopic surgeries of endometriomas,chemotherapy of female cancers have been studied.Some researchers have begun to pay attention to the potential relationship between AMH and the function of human brain.In the future,the applications of AMH maybe probably do significant contributions to make ideal and individualized treatment programs in more and more related fields.

[Objective] To disuse the traumatic mechanism,clinical feature and treatment of the occult osteochondral avulsion of the posterior ankle joint.[Method]The data of 6 patients had been reviewed.From 2003.9 to 2006.6,6 patients had been treated,including 4 male and 2 female,with the average ages of 31.7 years(27~38 years).They all had injury history of their ankle but no fracture or dislocation had been found in X-ray film immediatey after the trauma.Four of them had been treated by plastic cast fixation of their ankle for 3 weeks,2 received treatment without fixation,but all the patients suffered pain and tenderness in the medial-posterior or the lateral-posterior of the ankle with leg or/and food radiation.The symptoms were persistent even when they were rest.The diagnosis of osteochondrl avulsion fracture had not been made until they were admitted in 4 mouth to 1 year after the injury.The fractured bone debris were showed by X-ray film and CT scan.All patients had been treated by operation of ablating the fractured fragment.[Result]All symptoms in the ankle had disappeared 2~3 days after the operation and no recurrence during 6 mouth to 2 years follow up.[Conclusion]It shoud be attaching importance to the occult osteochondral avulsion in early time after ankle injury,and when the diagnosis is made,operation is the appropriate treatment.

Objective To establish D-dimer normal reference range in pregnant and postpartum women in Zhejiang Han population.Methods Plasma samples were collected from 669 healthy pregnant women, 578 healthy postpartum women, 8 venous thrombosis or DIC patients and 80 healthy non-pregnant women in Women′s Hospital, School of Medicine, Zhejiang University from March 2009 to August 2010.According to different gestational week, postpartum days and delivery pattern, the healthy pregnant and postpartum women were stratified into 3 groups: (1) ≤13 weeks (n=120), 14-20 weeks (n=120), 21-27 weeks (n=145), 28-34 weeks (n=147), ≥35 weeks (n=137);(2) The first day after vaginal delivery (n=163), the second day after vaginal delivery (n=121);(3) The first day after cesarean sections (n=166), the second day after cesarean sections (n=128). These groups were further stratified based on age: ＜30 years old and ≥30 years old.All blood samples were drawn in citrate sodium anticoagulated blood.D-dimer concentration was determined by STA-R Evolution coagulation analyzer.Since D-dimer concentration showed non-normal distribution, the normal values (one-tailed) were established by using (P95) percentile method.The results of 8 patients were used to validate the established normal values.Results In the group of ＜30 years old, the D-dimer values[M(P25-P75)]in group of ≤13 weeks, 14-20 weeks, 21-27 weeks, 28-34 weeks, ≥35 weeks and healthy non-pregnant women were 0.25(0.17-0.37), 0.51(0.38-0.75), 0.75(0.57-1.10), 1.14(0.80-1.48), 1.60(1.14-1.89) and 0.20(0.10-0.28) mg/L, respectively, which showed statistical difference(H=239.24, P＜0.05).In the group of ≥30 years old, the D-dimer values of the above different groups were 0.28(0.14-0.38), 0.50(0.36-0.65), 0.83(0.59-1.41), 0.93(0.68-1.37), 1.47(1.22-1.84) and 0.17(0.12-0.25) mg/L, respectively, which also showed statistical difference(H=127.75, P＜0.05).In the group of ＜30 years old, the D-dimer values were 2.45(1.51-3.77), 1.30(0.97-1.96), 2.68(1.52-3.74) and 1.55(1.10-2.10) on the first and second day after vaginal delivery and cesarean section, respectively, which showed statistical difference (H=64.85,P＜0.05).In the group of ≥30 years old, the corresponding values were 2.20(1.33-3.54), 1.33(1.02-2.14), 2.27(1.66-3.17) and 1.62(1.26-2.69), respectively, which also showed statistical difference(H=18.64, P＜0.05).D-dimer normal values were established based on different gestational week, postpartum days and delivery pattern.The normal values of ≤13 weeks, 14-20 weeks, 21-27 weeks, 28-34 weeks and ≥35 weeks were ≤0.64 mg/L, ≤1.54 mg/L, ≤2.60 mg/L, ≤3.01 mg/L and ≤3.19 mg/L, respectively. The normal values of 1st day after vaginal delivery, 2nd day after vaginal delivery,1st day after cesarean sections and 2nd day after cesarean sections were ≤7.83 mg/L, ≤3.29 mg/L, ≤9.95 mg/L and ≤3.80 mg/L.All 8 patients showed positive results with the above normal values.Conclusion D-dimer normal values in pregnant and postpartum women in Zhejiang Han population are established, which can improve the application values of D-dimer in the pregnant and postpartum population.

The effect of gelatin on anaero-cultivation of Bifidobacterium adolescent is and stabilization of its living cell in dried preparation was investigared. It was shown that the well-distributed mixture of gelatin and medium could have a cushioning effect on pH reduction resulting from acid-production while incubating, and the dried mixture comprising living cell of bifidobacterium adolescentis was prepared, in which the stability and viability of cell come from cultures of gelatin mixture was increased compared with that without gelatin mixture. It was shown that oxygen toxicity to anaerobic cell was well reduced because of cell immobilization by the gel mixure after drying with saccharide substance , and then fermentable dynamics in 50L fermentor was tested as well as the relationship of growth kinetics, pH, dissolved oxygen rate, and content of soluble solids.

AIM: There has been accumulating evidence demonstrating that activators for peroxisome proliferator-activated receptor ? (PPAR?) have antiinflammatory, antiatherogenic, and vasodilatory actions. We investigated the effect of PPAR? activator, fenofibrate, on trombin-induced endothelin-1 (ET-1) expression in cultured vascular endothelial cells. METHODS: Bovine aortic endothelial cells (BAECs) were treated with the PPAR? activator, fenofibrate. The ET-1 concentrations were evaluated by radioimmunoassay. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the ET-1 mRNA expression. RESULTS: Thrombin(10U/L) induced ET-1 release in BAECs [(22.4?4.7) nmol/g protein vs control (13.2?1.6) nmol/g protein, P

AIM:To investigate the role of p38 MAPK/ATF-2 pathway in C-relative protein ( CRP)-induced endothelial cell activation.METHODS:Human coronary artery endothelial cells ( HCAEC) were cultured and were used between passages 3 and 7.CRP served as a stimulus for endothelial cell activation.Western blotting was performed to de-termine the expression and phosphorylation of eNOS, p38 and ATF2.ELISA was carried out to detect the levels of ICAM-1, VCAM-1 and MCP-1 released from HCAEC.Pharmacological p38 inhibitors SB203580 and SB202190 were used to de-termine the effect of p38/ATF-2 pathway.RESULTS:CRP reduced the p-eNOS level in a concentration-dependent man-ner and induced the release of ICAM-1, VCAM-1 and MCP-1.The p38/ATF-2 pathway was activated by CRP treatment. SB203580 and SB202190 partially rescued p-eNOS level and suppressed the secretion of ICAM-1, VCAM-1 and MCP-1. CONCLUSION:p38MAPK/ATF-2 pathway participates in CRP-induced endothelial activation.

AIM:To study the correlation of serum uric acid ( UA) level with carotid plaques and arterial stiff-ness in the patients with essential hypertension ( EH) , and to explore the predictive value of serum UA for evaluating EH preclinically .METHODS:A total of 92 patients with EH and 30 healthy individuals were enrolled .The value of UA and other indicators were detected .B-mode ultrasound examination was performed to measure the common carotid artery intima -media thickness ( IMT) and the sites of plaque in the internal carotid-artery, external carotid artery and carotid bifurca-tions.Carotid-femoral arterial pulse wave velocity ( CFPWV) was assessed by Complior?atherosclerosis measurement in-strument.RESULTS:The serum level of UA in the patients with EH was higher than that in control group [(361.51 ± 83.81) μmol/L vs (317.03 ±62.22) μmol/L, P<0.05].The mean value and abnormal rate of IMT between hyperten-sion group and control group were significant difference [(0.69 ±0.14) mm vs (0.60 ±0.12) mm, 42.39%vs 10.00%, P<0.05].In 92 EH patients, 45 cases had carotid plaques .These 45 cases were divided into 3 groups according to the plaque severity, among which the serum UA level had statistically significant differences [(285.25 ±78.41) μmol/L, (341.19 ±63.99) μmol/L and (401.33 ±88.49) μmol/L, P<0.05].Compared with rigid plaque group ( n=34), the serum UA level in soft plaque group (n=11) was significantly higher [(389.00 ±69.45) μmol/L vs (323.03 ± 72.71) μmol/L, P<0.05].A stepwise multiple linear regression analysis demonstrated that age ( r=0.414), systolic blood pressure (r=0.224), pulse pressure (r=0.270) and uric acid (r=0.219) were predisposed factors for higher CFP-WV (P<0.05).CONCLUSION:UA is one of the risk factors causing hypertension .Serum UA level may reflect the sever-ity and stability of carotid plaques .The increased arterial stiffness is closely related to the increased serum UA level in EH .

Objective:To optimize the formula of metronidazole and borneol sustained-release films. Methods: The mass ratio of Rhizoma Bletillae polysaccharide and polyvinyl alcohol 124(PVA-124) and the dosage of glycerol and sodium carboxymethyl cellulose ( CMC-Na) as the influencing factors ,the appearance of films and the release rate of metronidazole at 0. 5h and 4h as the comprehen-sive evaluation indices, the formula of the film-forming materials was optimized by orthogonal test. Results:The mass ratio of Rhizoma Bletillae polysaccharide and PVA-124 was the key factor affecting the quality of the films. When the mass ratio of Rhizoma Bletillae pol-ysaccharide and PVA-124 was 20∶80, and the dosage of glycerol was 3. 5g and that of CMC-Na was 0. 14g, the appearance of the films was satisfied, the release rate of metronidazole at 0. 5h and 4h was 25. 17% and 69. 64%, respectively, and the average cumulative re-lease rate at 8h was over 90%. Conclusion:The films prepared by the optimized formula are flat, smooth, clean and moderately soft, which can not only remain the drug release characteristics of the films made by the original formula, but also exhibit the pharmacologi-cal effect of Rhizoma Bletillae.
