Studies have shown that women's menopause caused by permanent cessation of ovarian function is closely related to lipid metabolism disorders. Er-xian Decoction has been used in the clinical treatment for gynecological diseases and has a good effect on diseases related to reduced sex hormone function. In this study, metabolomics was performed on bilateral ovariectomized model rats within 12 weeks after modeling to mimic the physiological state of menopausal women in different menopausal stages and Er-xian Decoction dosed model rats. The results of liver oil red O staining sections showed lipid metabolic disorder of bilateral ovariectomized model rats and the regulating effects of Er-xian Decoction. 46 potential biomarkers (6 steroid hormones, 3 sphingolipids, 11 phospholipids and 26 glycerides) in plasma and 32 potential biomarkers (1 steroid hormones, 20 phospholipids and 11 glycerides) in liver were obtained based on lipidomics analysis. Then, we analyzed the differential metabolic pathways and construct the lipid metabolism network significantly regulated by Er-xian Decoction. The results provided valuable information for in-depth understanding of the gradual changes on lipid metabolism disorders under menopausal conditions and the characteristics and mechanisms of compound Er-xian Decoction's regulatory effects. The study complied with the procedures established by the Animal Experiment Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences and passed the animal experiment ethics examine (No. 00000918).

Objective To study the conventional MRI and dittusion weighted imaging(DWI) features of Japanese encephalitis(JE)in children.Methods Sixteen patients with JE were included. Conventional MRI and DWI sequences were performed in all patients.Seven patients received MRI within 10 days of onset and 9 after 10 days.The appearances on DWI and T_2 WI were recorded.The ADC values of lesions were calculated,and then were correlated with the corresponding time interval between onset of neurological symptoms and MRI scanning.Results The lesions of JE mainly showed long T_1 and long T_2 signal intensity on MRI.The thalami were the most frequently involved areas,and 15 out of 16 showed thalamic involvement and 6 patients only showed thalamic abnormalities without other lesions.Seven patients within 10 days of onset showed lesions with high signal intensity on both DWI and T_2WI,but whole or partial lesions showed clearer on DWI than on T_2WI,and 2 patients showed extra lesions that were invisible on T_2WI.As for the other 9 patients after 10 days of onset,the lesions showed clearer on T_2WI than on DWI. There was a direct correlations between thalamic ADC values and the disease duration (r=0.84,P

Objective To study the sources and the relationship between the management and the outcome of hemorrhage after cephalic pancreatoduodenectomy.Methods The clinical data of 370 patients who underwent pancreatic resection at the Lihuili Hospital and the Second Affiliated Hospital of Zhejiang University were retrospectively analyzed.Results Postoperative bleeding occurred in 35 patients with 11 deaths.Among those intraabominal bleeding occurred in 14 cases and gastrointestinal hemorrhage occurred in 22,with one case suffering from both.Bleediug developing within 72 hours after operation in 12 cases (early-stage group),which was caused by improper intraoperative homeostasis.In other 23 cases,bleeding 72 hours after operation(later stage group)was caused by the erosion following pancreatic and/or bile leakage.Relaparotomy was performed in 13 cases and endoscopic homeostasis was performed in 3. Relaparotomy or endoscopic homeostasis was superior to that of conservative therapy in the early-stage group (P0.05).Pancreatic or bile leakage was identified as the significant risk factors for the postoperative bleeding.Conclusions In order to prevent the postoperative hemorrhage and to reduce the mortality of pancreatic resection,skillful techniques,expeditious homeostasis,proper management of stump pancreas and the prevention of pancreatic and bile leakage are essential.

OBJECTIVETo evaluate the efficacy of trimetazidine on insulin resistance in patients with coronary heart disease (CHD).

METHODSA cohort of 119 CHD patients were randomly divided into groups A and B receiving the same basic therapy, and the patients in group B were given additional trimetazidine 20 mg 3 times daily for 8 weeks. Before and after treatment, the changes in blood glucose, insulin levels and insulin sensitivity index were evaluated.

RESULTSThe patients in group B showed better outcome than those in group A. After 8 weeks' trimetazidine therapy, the fasting insulin and that at 2 h after oral glucose were decreased (P<0.01), and the insulin sensitivity index was improved (P<0.01).

CONCLUSIONTrimetazidine may produce obvious therapeutic effect on insulin resistance in CHD patients.

Objective: To study the factors and preventive method of post-operative complications of spinal implant operation. Methods: The post-operative complication of 451 cases who had undergone spinal implant operation were analysed retrospectively. The relative factors of complications were analyzed. Results: Infection, thrombosis of deep vein and failed fusion were the most common complications. Among the factors, the age, operation time and blood lose during operation were closely related with the complication. Using antibiotic was effective to reduce the infection. Conclusion: It is effective to reduce the post-operative complication of spinal implant operation by proper pre-operative evaluation. Using antibiotic to control other diseases is also effective.

Objective To assess the effective length of jejunal graft when the 3~(rd) intestinal artery is u- tilized as vascular pedicle and afford a reliable theoretic base for clinical esophageal reconstruction.Methods In 32 formalin preserved and 21 fresh cadaver specimens,the diameter of 1st to 5th intestinal arteries and diameter of arterial arches are measured with linear calibre.Measure the length of jejunum that can be harves- ted as graft when the arches are extended.In the 21 fresh specimens,the 1st,2nd,4th and 5th intestinal ar- teries are ligated,acetic ester stained with red dye were injected into the lumen of 3rd intestinal artery via catheter.Extent of distribution of the arteries to the jejunum was observed.And then red ABS solution was in- jected into the 3rd intestinal artery to make into cast specimen.The blood supply distribution of jejunum through 3rd intestinal artery-arterial arch and communicating system were observed again.Results The di- ameter of the 3rd intestinal artery was the largest among the 1st to 5th intestinal arteries.The length of jejunum vascularized by 3rd intestinal artery can be as long as (142.2?62.3) (69.0～206.60cm) in acetic ester in- filtrated specimens.While in ABS east specimen,the average available extent of donor jejunum was(30.8?7.3) (23.0～37.3cm).Conclusion As observed by this applied anatomy study,the jejunum graft vascu- larized by 3rd intestinal artery alone has sufficient length to meet the need of esophageal reeonstrution.

Acute coronary artery syndrome (ACS) was confirmed by coronary arteriography in 398 patients,and 378 healthy persons served as the control group.Serum uric acid in ACS and control group showed normal distribution,and serum uric acid level in ACS group (322?107 )?mol/L was significantly higher than those in control group (302?77)?mol/L (P＜0.01 ).The prevalence of hyperuricemia (HUA) was 27.0% in male patients and 25.2% in female.Systolic blood pressure,diastolic blood pressure,fasting plasma glucose,total cholesterol,triglycerides,creatinine and blood urea nitrogen in ACS group were higher than those in control group (all P＜0.01 ).Muhivariable analyses adjusted for age and sex indicated that raised fasting plasma glucose,total cholesterol,uric acid and mean arterial pressure were risk factors for coronary artery stenosis in ACS,and HUA played a role in the pathogenesis of ACS.
