Objective To evaluate the therapeutic effect of lentinan combined with conventional antituberculous therapy in women with pelvic tuberculosis.Methods A total of 90 women with pelvic tuberculosis were enrolled and recruited into a control group and a treatment group by random number table,45 in each group.The control group was treated with anti-tuberculosis program (2HRZE/4HRE),while the treatment group was treated with lentinan tablets on the basis of the control group.Both groups were treated for 6 months.Serum levels of carbohydrate antigen 125 (CA125) and erythrocyte sedimentation rates (ESRs) were determined before and after treatment,and the therapeutic effect was evaluated.Results After treatment,the serum CA125 level (28.61 ± 9.08 U/ml vs.39.72 ± 12.13 U/ml;t=4.919,P＜0.01) and the ESR (36.13 ± 8.33 mm/h vs.41.35 ± 12.45 mm/h;t=2.338,P＜0.05) in the treatment group were significantly lower than those in the control group.The negative rate of serum CA125 after treatment than before treatment in the treatment group (93.3％ vs.20.0％;X2=46.335,P＜0.01) and the control group (82.2％ vs.8.9％;X2=37.396,P＜0.01);but there was no difference in negative rate of serum CA125 after treatment between two groups (X2=1.6571,P=0.198).The total effective rate in the treatment group was significantly higher than that in the control group (93.3％ vs.77.8％;X2=4.406,P=0.036).Conclusion Lentinan combined with conventional antituberculous therapy is effective in treatment of pelvic tuberculosis in women.

ObjectiveTo investigate the related factors which influencing endoscopists in the accuracy of diagnosis of chronic atrophic gastritis (CAG). Methods With retrospective analysis method,from January to December in 2009,10 765 chronic gastritis cases underwent endoscopy examination in Renji Hospital,school of medicine,Shanghai Jiaotong University were collected.The influence of congestion and exudation,gastric ulcer,bile reflux,gastric polyps and H.pylori infection under endoscopy on CAG endoscopic and pathological diagnosis was analyzed.ResultsThe percentage of histopathological diagnosed CAG was 69.41％,endoscopic diagnosed CAG was 54.27％. The coincidence rate was 62.30％.2575 cases were H.pylori positive (23.92％),the coincidence rate between endoscopic and histopathological diagnosis in H.pylori positivc cascs was 90％.of that of H.pylori negative cases (β=-0.1067,P＜0.05).The coincidence was positively related to age.For each 1 year increase in age,the coincidence rate increased by 0.01 time [OR=exp(0.00855)=1.01]; For each 10-year increase in age,the coincidence rate increased by 0.09 time [OR=exp(0.0855) =1.09].The coincidence rate was negatively related to congestion and exudation.The coincidence rate of CAG between endoscopic and histopathological diagnosis in cases with congestion and exudation was 40％ of that without congestion and exudation (β=-0.1067,P＜0.01).ConclusionCAG diagnosed under endoscopy was somewhat subjective and should be combined with histopathological analysis.The patients' age,H.pylori infection,congestion and exudation may have influence on the coincidence rate between endoscopic and histopathological diagnosis of CAG.

Objective To study the content changes of wilforlide A in Xinfeng capsules before and after compatibility.Methods The content of wilforlide A was determined in Xinfeng capsules ester content and in Tripterygium wilfordii Hook.f.single solution by TLCS method.Developing solvents:chloroform and methanol (85:1),scanning wavelength:230 nm.Results Wilforlide A showed a good linear relationship in 1.700-5.100p g,the regression equation is Y =1 118.766 + 3 253.751 X (r =0.999).The average recovery of the wilforlide A in Xinfeng capsules was 102.84％,and RSD was 3.64％.The average recovery of the wilforlide A in the Tripterygium wilfordii Hook.f.single decoction was 98.14％,and RSD was 2.21％,compatibility levels before and after the change (compatibility with 0.179mg/g,0.136mg/g after compatibility).Conclusion The established TLCS method was simple,specific and accurately quantitative.The comparative study found that the compatibility of Xinfeng capsules Tripterygium reduced the content of wilforlide A,which may be related to decreasing toxicity.

Objectives To examine the association of the maternal high-fat (HF) diet with increased susceptibility to obe-sity and the development of metabolic diseases in their offspring, and observe difference in the effect of maternal vs. acquired high fat diet on metabolic state in their offspring. Methods A total of 15 SD female rats were divided into HF diet group (group H, n=9) and control diet group (group C, n=6). After fed on different diet for seven weeks, they were mated at the age of ten weeks and became pregnant. Their offspring were then divided to groups CH and HH fed HF diet and groups CC and HC fed control diet. At the age of 3 and 8 weeks, the metabolic markers and the liver pathohistological evidences of their offspring were obtained. Results The body weight, area under curve (AUC) of glucose tolerance, cholesterol and triglyceride were all higher in group H than those in group C (P<0.05) before pregnancy. The offspring of group H had a higher body weight than the offspring of group C at the age of 3 weeks (P=0.002), and no difference in AUC was found between two groups (P>0.05). At the age of 8 weeks, there was no difference in fasting glucose and insulin levels among the four offspring groups. The AUC and body weight were higher in group H than in group C (main effect of maternal diet, P=0.024, P=0.013). The AUCs were also higher in groups CH and HH than groups CC and HC respectively (main effect of acquired diet, P=0.041). The levels of total cholesterol, triglycerides and LDL at the age of 8 weeks were all higher in HH and CH groups than those in HC and CC groups (main effect of acquired diet, P=0.008, 0.007, 0.000, respectively). Their histological analysis at 8 weeks showed different degrees of fatty liver in HH, HC and CH groups, and normal liver in CC group. Conclusions Maternal HF diet may result in increased body weight, fatty liver and impaired glucose tolerance in their adult offspring, and thus increase the risk of developing metabolic diseases at their later age. .

Wuxistatin, a novel and potent statin, is converted from lovastatin by Amycolatopsis sp. CGMCC1149. In the bioconversion, lovastatin is firstly hydroxylated by a hydroxylase. To obtain the critical hydroxylase, a novel hydroxylase gene was isolated from Amycolatopsis sp. CGMCC1149 by Degenerate PCR and Self-Formed Adaptor PCR and expressed in Escherichia coli. BLAST sequence analysis revealed that the gene belonged to cytochrome P450 gene superfamily and could encode a 403-amino-acid protein with a molecular weight of 44.8 kDa. The secondary structure prediction result showed that this protein contained many typical functional regions of P450, such as oxygen binding site, ion-pair region and heme binding region. Meanwhile, a catalytic function verification system was constructed by NADH, ferredoxin and ferredoxin reductase which could catalyze lovastatin hydroxylation into the target product. These would be helpful for further studies in large-scale production of wuxistatin.

Objective To explore the application value of SWI in hyperacute ischemic cerebral infarction.Methods 40 patients with massive hyperacute ischemic cerebral infarction in middle cerebral artery (MCA)territory were enrolled successively who underwent MR imaging with conventional MRI,DWI,MRA and SWI sequence immediately.The MR images were analyzed by two senior neuroimaging physicians and the results were recorded.The number of thrombosis at MCA showed on SWI was compared with that showed on conventional MR sequence and the number of MCA stenosis or occlusion showed on MRA,the length of thrombosis and the number of cases with veins increased in infarct area were also compared.Results The number of thrombosis at MCA showed on SWI was more than that showed on conventional MR sequences significantly (23 vs 12,χ2 =6.146,P =0.013),and was lower than that showed on MRA (23 vs 24,χ2 =0.052, P =0.820)slightly.Thrombosis at MCA trunk and its small branches were found in the meantime in 2 cases .The length of thrombosisshowed on SWI was longer than that showed on conventional MRI sequences (25.7 mm±9.4 mm vs 14.6 mm±8.5 mm,t=14.395,P =0.000), significantly and the number of patient with veins increased in infarct area showed on SWI was more than that showed on conventional MR sequences (21 vs 12,χ2 =4.1 78,P =0.041)significantly.Conclusion SWI has usefull application value in patients with hyperacute massive ischemic cerebral infarction.

Objective To investigate the prognosis and efficiency of glucocorticoid and immunosuppressor in the treatment of idiopathic membranous nephropathy(IMN)in children. Methods A retrospective analysis of 35 cases of biopsy - proven membranous nephropathy without secondary factors was performed,who were found present with ne-phrotic proteinuria and admitted to hospital from March 2004 to July 2013,to explore the efficiency of treatment with glucocorticoid and immunosuppressor and its prognosis. Results The 35 IMN cases included 18 boys and 17 girls,and the ratio was 1. 1∶ 1. 0. The mean age at onset was(11. 3 ± 0. 5)years with a range of 3. 0 - 17. 1 years. Five cases with gross hematuria,24 cases present with microscopic hematuria,8 cases with hypertension,1 case with chronic renal insufficiency,and 2 cases were complicated with thrombosis. According to membranous nephropathy staging criteria,9 cases(25. 7% )were in stage Ⅰ,16 cases(45. 7% )in stage Ⅱ,10 cases(28. 6% )in stage Ⅲ;about 94. 3%(33 / 35 cases)had mesangial cells and mesangial matrix with mild to moderate hyperplasia. They were all treated with glucocor-ticoid initially and one of them showed sensitive to flucocorticoid but developed flucocorticoid resistance after relapse, while all the others were flucocorticoid - resistant. Cyclophosphamide A(CsA)was introduced to 17 cases and at least lasted for 3 months,in which 13 cases(76. 5% )reached complete remission and 3 cases reached partial remission, while 1 case didn't achieve remission,and the mean time for proteinuria to disappear was(4. 9 ± 3. 7)months;5 cases were treated with Mycophenolate mefetil( MMF),among which 4 cases reached complete remission in 2 months,4 months,5 months,and 9 months separately,while 1 case reached partial remission. Cyclophosphamide(CTX)was intro-duced to 6 cases,in which the mean cumulative dosage was(91. 2 ± 46. 5)mg/ kg,among them 1 case(87 mg/ kg) reached complete remission,1 case(160 mg/ kg)partial remission,but 4 cases didn't achieve remission. One case reached remission after Rituximab(RTX)was introduced. One case got partial remission after Leflunomide(LEF)was introduced,and the complete remission rate was higher in those treated with combined therapy of glucocorticoid and CsA than those treated with glucocorticoid only(76. 5% vs 12. 5% ,P = 0. 004),but the total efficacy showed no difference (94. 2% vs 62. 5% ,P = 0. 081). The complete remission rate(76. 5% vs 38. 5% ,P = 0. 042)and total efficacy (94. 1% vs 61. 5% ,P = 0. 040)were higher in those with combined therapy of steroid and CsA than those treated with steroid and other immunosuppressor. The complete remission rate(76. 5% vs 16. 7% ,P = 0. 018)and total efficacy (94. 1% vs 33. 3% ,P = 0. 008)were also higher than those treated with steroid and CTX,but the complete remission rate(76. 5% vs 80. 0% ,P = 0. 687)and total efficacy(94. 1% vs 100. 0% ,P = 0. 773)showed no difference com-pared with those treated with steroid and MMF. Conclusions IMN shows glucocorticoid resistance mostly,while CsA had definite efficiency and may be better than CTX. And the efficiency of MMF should be noted.

Objective To investigate microstructure of the corpus callosum(CC) in subacute diffuse axonal injury(DAI) patients and its the longitudinal change in a short time.Methods 21 patients with subacute DAI were enrolled successively in this study,and in which 12 patients were reexamined followed-up with DTI a month later (31.5 d±6.2 d,28-43 d),and then 12 gender and age matched healthy controls were recruited.The DTI data of all subjects were acquired on at a 3.0T MRI.The CC was divided into six segments:the genu, rostral mid-body, anterior mid-body,posterior mid-body, isthmus, and splenium.ROIs were placed on each segment on color fractional anisotropy (FA) maps in the midsagittal plane manually.The FA and apparent diffusion coefficient(ADC) values of each subregion of CC were measured and compared between subacute DAI group,follow-up group and controls respectively.In addition,a related analysis between DTI parameters of each sub-region of CC and GCS on admission was done by using person correlation analysis.

Objective To investigate the ultrasound characteristics,etiology and prognosis in hydrops fetalis.Methods From September 2002 to May 2010,156 hydrops fetalis presented in Shenzhen Maternity and Child Healthcare Hospital were studied retrospectively,including ultrasound characteristics,etiology,and prognosis.Results All of the 112 typical hydrops fetalis,20 cases with isolated ascites,8 cases with isolated pleural effusion,7 cases with isolated pericardial effusion,5 cases with isolated subcutaneous edema,4 cases with isolated placental thickening were observed by ultrasonography.The major etiology and associated diagnosis consisted of 35.9％ (56/156) of non-immune anemia,9.6％ (15/156) of cardiac abnormalities,7.1％ (11/156) of intrauterine infection,6.4％ (10/156) of twin problems,5.8％ (9/156) of meconium peritonitis,5.1％ (8/156) of thoracic-lung disease,4.5％ (7/156) of chromosomal abnormalities,1.9％ (3/156) of immune anemia.Alpha thalassemia was the most common non-immune anemia (96％,54/56).An etiology and associated diagnosis could be determined in 81.4％ ( 127/156 ) of cases.Follow-up data showed that 7 cases were fetal death,110 women elected to terminate their pregnancies,3 cases lost follow-up,the other 36 cases preserve continuing pregnancy,including 28 liveborn infants and 8 fetal deaths.Etiology of twin-twin transfusion syndrome,meconium peritonitis,congenital chylothorax,intrauterine infection,cardiac abnormalities and so on had survived fetuscases.The survival rate of typical hydrops fetalis in the present series was 3.6％ ( 4/112 ).Conclusions Ascites is the most common characteristics of sonogram in hydrops fetalis.The etiology of hydrops fetalis is extremelycomplex.The prognosis is associated with the etiology and hydrops subtype.
