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 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.

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. .

Objective:Based on the microarray data mining method, the function and pathway of differential genes were analyzed after the differential genes were screened. At the same time, the core genes that determine the prognosis of pediatric hepatoblastoma were screened by coexpression network, and their predictive ability was evaluated.Methods:The microarray expression profile of pediatric hepatoblastoma used in this study was from the European Institute of bioinformatics (http: //www.ebi.ac.uk/embl/). The deadline for data collection was December 31, 2018. Firstly, the differentially expressed genes (gene expression level increased to 2 times or decreased to 1/2 of the original) were screened by SAM method, then the core genes were screened by coexpression network model based on dimension reduction principle, and the gene regulation evaluation score was calculated by MCODE algorithm to evaluate its regulation ability in the whole network model.Results:According to the enrichment results of 213 differentially expressed genes, the highest enrichment degree of signal pathway was metabolic pathways (2 122.529). The misjudgment rate of signal pathway enrichment results was less than 0.001, and the misjudgment rate was statistically significant by SAM method ( P<0.001). A total of 213 differentially expressed genes in different prognosis groups were used as the basis for the construction of the coexpression network. A total of 12 differentially expressed genes were included in the coexpression network. Using the poor prognosis group as the experimental group, and the better prognosis group as the control group, the MCODE algorithm was used to calculate the gene regulatory ability score. The results showed that the highest gene for determining the prognosis control ability of children hepatblastoma was ADH1A gene with a score of 19. In addition, the regulatory ability scores of HAO1, ADH1B, ALDOB and DPYS genes were higher than or close to 5, so they could be considered as the core genes in the coexpression network module. Conclusions:According to the results of coexpression network model, ADH1A gene is closely related to the occurrence and development of hepatoblastoma in children, and its molecular biological evidence needs to be further explored to guide the clinical development of tumor targeted intervention therapy.

Objective To investigate the role of autophagy in radiation-induced death response of human nasopharyngeal carcinoma cells.Methods MTT method was used to detect cell viability of CNE-2 cells in different time after irradiation.Clonogenic survival assay was used to evaluate the effect of autophagy inhibitor (chloroquine phosphate) and autophagy inductor (rapamycin) on radiosensitivity of nasopharyngeal carcinoma cells.Cell apoptosis was assessed by flow cytometry.The expressions of LC3 and P62 were measured with Western blot.Cell ultrastructural analysis was performed under an electron microscope.Results Irradiation with 10 Gy induced a massive accumulation of autophagosomes accompanied with up-regulation of LC3-Ⅱ expression in CNE-2 cells.Compared with radiation alone,chloroquine phosphate (CDP) enhanced radiosensitivity significantly by decreasing cell viability (F =25.88,P ＜ 0.05),autophagic ratio (F =105.15,P ＜ 0.05),and LC3-Ⅱ protein level(F =231.68,P ＜0.05),while up-regulating the expression of P62 (F =117.52,P ＜ 0.05).Inhibition of autophagy increased radiation-induced apoptosis (F =143.72,P ＜ 0.05).Rapamycin (RAPA) also significantly decreased cell viability,but increased autophagic ratio and LC3-Ⅱ protein level while down-regulated the expression of P62.Induction of autophagy increased radiation-induced apoptosis(F =167.32,P ＜ 0.05).Conclusions Blockage of autophagy with CDP could enhance radiosensitivity in human nasopharyngeal carcinoma cells,suggesting that inhibition of autophagy could be used as an adjuvant treatment to nasopharyngeal carcinoma.

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.

BACKGROUND:Mason II type and III type radial head fractures with massive bone are mainly treated by open reduction and metal fixation, but metal implants have to be removed in the second operation, which increased patients’ travail and financial burden. Absorbable screw/rod also can be used to treat radial head fractures, and has its special advantages due to the low price and no second operation. OBJECTIVE:To compare the clinical therapeutic effects of absorbable rod and Herbert screw for the treatment of Mason II or III type radial head fractures. METHODS:A total of 80 patients with Mason II and III type radial head fractures were equal y assigned to experimental and control groups. They received open reduction and internal fixation. The experimental group was treated with absorbable rod and the control group received Herbert screw. RESULTS AND CONCLUSION:A total of 79 patients were fol owed up for averagely 34 months. No significant difference in average operative time, fracture healing time, Broberg and Morrey elbow scores and incidence of complications was detected between the experimental and control groups (P>0.05). However, treatment costs were lower in the experimental group than in the control group (P<0.05). Results indicated that the therapeutic effects between absorbable rod and Herbert screw for Mason II or III type radial head fractures were similar. However, absorbable rod for radial head fractures can avoid the second operation for removal of the implant. Therefore, we recommend absorbable rod in the choice of internal fixation materials.

Objective To Explore the significance of successful exposing and recognizing Zuckerkandl's tuhercle(ZT)during thyroidectomy.Methods Three hundred and seventy patients(501 sides) underwent lobectomy or total thyroidectomy from January 2009 to June 2011 were included in this study.The ZT was assessed in terms of its presence or absence,size and anatomical association with the recurrent laryngeal nerve(RLN)and superior parathyroid(SP).Results ZTs were found in 412 of 501 sides ( 82.2％ ),among which 368(89.3％ ) ZTs were located in the middle third of the lateral lobe of the thyroid gland.ZTs passed over the RLN in 379 of 412 sides(92.0％ ).When the ZTs were located in the middle or lower third of the lateral lobe of the thyroid gland,the SPs were all located in the cranial portion of ZT.The SP was adhered to the ZT in 80.1％ of the cases.RLN damage rate was 0.40％,and no SP damage occurred.Conclusion Exposing and recognizing Zuckerkandl's tubercle during thyroidectomy is of important clinical significance,which helps to identify and protect RLN and SP,so as to reduce surgical complications.
