Objective To demonstrate the validity of volumetric QCT and dual energy X-ray absorptiometry( DXA )in bone mineral density (BMD) measurement and compare the difference in discriminating osteoporotic postmenopansal women with and without vertebral fracture. Methods One hundred and eighteen postmenopausal women [ mean age (62. 1 ± 7.0) years ] who received thoracolumbar radiographic examination were enrolled and divided into four groups (normal, osteopenia, osteoporotic and osteoporotic fractured group) also based on their BMD value of lumbar vertebra(AP-SPINE) measured by DXA: >x- 1s,x- 1s-x-2s, 0. 05 ]. In osteoporotic groups, AP-SPINE was not correlated significantly with other variables except 3D-CORT ( R2 = 0. 189, P < 0. 01 ) ; parameters of App60,80,100,120 BV/TV% were correlated significantly with 3 D-TRAB (R2 = 0. 955, 0. 951,0. 941,0. 912, P < 0. 01, respectively) and 2 D-TRAB(R2 = 0.912, 0.910, 0.878, 0.821, P < 0.01, respectively). The precision of 3D-BMD measurement was between 0. 70%--2. 25%. Conclusions Parameters derived from 3D-vQCT technique can discriminate osteoporotic postmenopausal women with fractured vertebrae from those without fractured vertebrae, and have better the capability than DXA. Among them, 3D-INTGL was the best parameter for diagnosing serious osteoporosis. App BV/TV% could be used to reflect the lost of trabecular bone precisely and to clinically predict fracture risk.

ObjectiveTo study the effect of 1,25-(OH)2D3 analogs paricalcitol on proteinuriaindiabeticnephropathy (DN)rats, andtoinvestigateitspossiblemechanism.Methods DN model rats were established by intraperitoneal injection with streptozotocin.All the DN rats were randomly divided into the paricalcitol group(group P ) and DN group(group D).Healthy rats were chosen as healthy control group(group N).24-h urinary protein and serum biochemical indicators were examined after 12 weeks.ELISA was applied to detect the level of renin and Ang Ⅱ in the kidney.Immunohistochemistry and real-time PCR were used to detect the protein and mRNA expression of heparanases(HPA)and podoein.Results Compared with group N,24-h urinary protein,serum creatinine,renin and Ang Ⅱ in group D and group P were markedly increased,and they were significantly higher in group D as compared to group P (all P＜0.05).Compared with group N,the expression of HPA protein and mRNA in group D and group P increased markedly,and higher expression was found in group D(all P＜0.05).The expression of podocin protein and mRNA in group D and group P decreased markedly,and lower expression was found in group D(all P＜0.05).Renin level was positively correlated with HPA protein expression (r=0.78,P＜O.OS),negatively correlated with podocin protein expression(r=-0.63,P＜O.05),and not correlated with their mRNA expression.Conclusion Paricalcitol can significantly reduce the proteinuria,which may be associated with the inhibition of renin by down-regulating protein expression of HPAin glomerular basement membrane and up-regulating protein expression of podocin in podocyte.

ObjectiveTo evaluate the rationale of combined evisceration for the treatment of advanced gastric cancer.MethodsThe clinical data of 137 cases with advanced gastric cancer treated with combined evisceration from 1994 to 2001 were analyzed retrospectively.ResultsEleven cases underwent combined hepatectomy, 25 cases with splenectomy, 13 with transverse colectomy, 15 with cholecystectomy, 4 with auxiliary adrenalectomy, 38 with splenectomy plus distal pancreectomy, 13 with pancreatoduodenectomy, 18 with other adjecent evisceration. The operative mortality rate was nil. The 1-,3-,5-year survival rate were 60.2%,26.3% and 16.6% respectively.Conclusions Combined evisceration for treating advanced gastric cancer was feasible and yielded a longer survival.

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).

The purpose of this study is to systematically investigate the characteristics of absorption and metabolism of oxymatrine (OMT) using rat intestinal perfusion model. Ultra performance liquid chromatography (UPLC) and high performance liquid chromatography-electrospray ionization-quadrupole-time of flight mass spectrometry (HPLC-ESI(+)-Q-TOF-MS) were used to test absorption of OMT in intestine at 100, 200 and 400 µmol · L(-1). The absorption rate and permeability of OMT is not dependent on concentration, but through passive absorption in intestine (P > 0.05). In the rat intestine, the absorbed amount of OMT was significantly different in four sections of the intestine in an order of duodenum > jejunum > ileum > colon (P < 0.05). OMT is metabolized into two metabolites in duodenum and jejunum, and matrine (MT) is the major one.

Objective To build the indicators system for clinical pathway management as required by clinical pathway control.Methods An indicators system was proposed by means of evidence-based review,focus group discussions,and ratings of the indicators' importance by doctors and nurses.A multidisciplinary panel of 60 experts from across the country were selected.A 3-round Delphi survey was made on the proposed indicators.The weights of the indicators were established by analytical hierarchy process (AHP).The response rate,Cronbach's α,and the authority coefficient of experts were used as a measure of reliability.Results The response rates of the 3 rounds were 85％,70％,and 94％; the experts authority coefficient was 0.80.The ccoefficient of variation falls with the rising number of consultations.The Kendall's W ranged from 0.40 to 0.83.Following the 3 rounds,consensus was achieved among experts as such a system comprising three first-level,9 second-level,and 36 third-level indicators.Conclusion The expert consultation has achieved reliable results.The established indicators system can serve as a useful instrument for standardized development of clinical pathways management and constant improvement.

AlM:To find better ways of treating ocular alkali burn, and to reduce the suffering of patients and social burden.METHODS:Totally 100 patients were graded according to the degree of chemical burns to four major groups, each half were randomly divided into the control group and the treatment group. Control group underwent conventional treatment. ln addition to conventional therapy, patients in each treatment group were also added a Breviscapine intravenous injection of 40mg daily. Corneal recovery time, changes in vision, degree of corneal opacity, number of corneal neovascularization and other complications were observed. Curative effects were analyzed statistically.
RESULTS:There was no significant difference in levelⅠgroup between control group and treatment group ( P>0. 05); There were significantly different in level Ⅱ, Ⅲand Ⅳ group ( P<0. 05 ). Compared to the degree of corneal opacity and the number of corneal neovascularization, the treatment group was obviously better than the control group(P<0. 05).
CONCLUSlON: Breviscapine in the treatment of ocular alkali burns can shorten the course of treatment, reduce corneal scarring, and improve vision.

Objective To summarize the diagnosis and surgical treatment of mesenteric cyst in children.Methods The clinical records of mesenteric cyst cases from January 2011 to December 2015 were reviewed retrospectively.The diagnosis and treatment options were analyzed, and the prognosis of laparoscopic surgery and laparotomy was compared.Results The main clinical symptoms included abdominal mass, abdominal pain, and abdominal distension.Abdominal ultrasound and/or CT scan were the diagnostic tools in all cases.Traditional laparotomy was performed in 14 cases, while laparoscopy in 7 cases (1 case switched to laparotomy).2 cases had emergency surgery due to acute abdomen, laparotomy and laparoscopy in each case.Simple cyst resections were completed in 14 cases, of which 2 cases with a small amount of residual in the mesenteric root.Intestinal resection and anastomosis were required in other 7 cases.The average time of hospital stay for laparotomy group was 12 days, and 10.14 days for laparoscopy group.There was no significant difference.All patients were discharged without postoperative complications.With 1-4 years follow-up, there was no recurrence.Conclusion The operation for mesenteric cysts depends on the relationship between the cyst and the adjacent bowel or organs, and the overall outcome is favorable.The selective use of laparoscopy will benefit more children.
