Objective To evaluate the efficacy of 10-day compound allantoin containing quadruple regimen in the treatment of chronic gastritis with Helicobacter pylori (H.pylori) infection,and to compare with the bismuth-containing quadruple therapy.Methods Altogether 173 patients with H.pylori positive chronic gastritis confirmed by gastric endoscope were divided into 10-day compound allantoin containing quadruple regimen group (n =43),24-day compound allantoin containing quadruple regimen group (n =46),10-day bismuth-containing quadruple regimen group (n =42) and 24-day bismuth-containing quadruple regimen group (n =42).After the treatment,the eradication rate of H.pylori,the rate of gastrointestinal symptoms (epigastric pain,bloating and belching) relief and the adverse effects of each group were observed.Intention-to-treat (ITT),per-protocol (PP) statistical analysis and chi-square analysis were performed for statistical analysis.Results H.pylori eradication rates of 10-day compound allantoin containing quadruple regimen group,24-day compound allantoin containing quadruple regimen group,10-day bismuth-containing quadruple regimen group and 24-day bismuth-containing quadruple regimen group analyzed by ITT were 90.7％ (39/43),91.3％ (42/46),90.5％ (38/42) and 88.1％ (37/42),respectively; while analyzed by PP were 90.7％ (39/43),93.3％ (42/45),90.5％ (38/42) and 90.2％ (37/41),respectively.And there were no statistical differences between groups (all P＞0.05).Ten days after the treatment,the rates of epigastric pain relief of 24-day compound allantoin containing quadruple regimen group and 24-day bismuth-containing quadruple regimen group were 81.1％ (30/37) and 78.8％ (26/33),respectively,the rates of bloating relief were 82.4％ (28/34) and 71.0％ (22/31),respectively,and the rates of belching relief were 76.9％ (20/26) and 75.0％ (21/28),respectively.There were no statistical differences between the two groups (all P＞ 0.05).However after 24-day treatment,the rates of epigastric pain relief of 24-day compound allantoin containing quadruple regimen group and 24-day bismuth-containing quadruple regimen group were 91.9 ％ (34/37) and 87.9％ (29/33),respectively,the rates of bloating relief were 94.1％ (32/34) and 87.1％ (27/31),respectively,and the rates of belching relief were 96.2％ (25/26) and 85.7％ (24/28),respectively.There were no statistical differences between the two groups (all P＞0.05).And the rates of epigastric pain and bloating relief increased after 24-day treatment compared with those of 10-day treatment,however the differences were not statistically significant between the two groups (all P＞ 0.05).In 24-day compound allantoin containing quadruple regimen group,the rate of belching relief was higher after 24-day treatment compared with that of 10-day treatment,and the difference was statistically significant (x2=4.127,P=0.042).No severe adverse effects were observed in each group,and there were no adverse effects such as oral metal odor,tongue black and melena in compound allantoin containing quadruple therapy.Conclusions Ten-day compound allantoin containing quadruple therapy as first-line approach in the treatment of chronic gastritis with H.pylori infection can get better H.pylori eradication and the efficacy is similar to bismuth quadruple therapy.Meanwhile the symptom relief rate is high and no obvious adverse effects were found.

Abstract: Objective　A survey on the plague foci in Qiaojia County of Jinsha River Basin was conducted to understand the composition of plague host vectors and the prevalence of plague among animals, to explore the occurrence and epidemic risk of plague, and to provide scientific basis for plague monitoring and control in this area. Methods　Seven villages and towns in Qiaojia County were selected as the research areas, and the cage night method and the clamp line method were used to investigate the small mammals and their surface parasitic fleas. The host animal organs, serum and surface parasitic flea's samples were collected. The plague indicator animal serum was collected simultaneously on the spot, and the collected host animal organs and flea's samples were cultured and detected for Yersinia pestis. The indirect hemagglutination test (IHA) was used to detect the fraction 1 capsular antigen (F1) antibody of the host animal and the indicator animal serum samples. Results　A total of 525 small mammals belonging to 3 orders, 6 families, 12 genera and 23 species were captured. The dominant species in farming areas were Apodemus chevrieri (31.05%), Niviventer confucianus (13.90%) and Anourosorex squamipes Milne-Edwards (11.43%). The dominant species in residential areas were Rattus norvegicus (66.67%) and Rattus tanezumi (20.00%). The rat densities in agricultural and residential areas were 20.98% and 1.00%, respectively. A total of 277 external parasitic fleas belonging to 15 species, 13 genera, 5 families were collected. The dominant species were Palaeopsylla remota (22.02%), Neopsylla specialis specialis (20.58%), Frontopsylla diqingensis (18.77%) and Ctenophthalmus (Sinoctenophthalmus) quadratus (11.55%), and the rat fleas index was 0.53. No Yersinia pestis was isolated from all rodent organs and flea samples. A total of 167 serum samples from dogs and 15 serum samples from rats were collected, and plague F1 antibody was detected by IHA. IHA detection of plague F1 antibody were negative. Conclusions　Qiaojia County has the distribution of the main host and main vector of plague, and the rat density is high, but the rat body flea index is low. There is no positive detection of plague host animals, vector fleas and indicator animals. It can be considered that the risk of plague occurrence and epidemic in the region is not high in the near future. It is necessary to further strengthen the monitoring and control of plague and other rodent-borne diseases in the region.

Objective:To explore the relationship of NSCL/P with MTHFR gene polymorphism in Xinjiang Uyghur and Han popula-tion and the ethnic difference.Methods:rs1801131 and rs1801133 polymorphism was detected by SNaPshot genotype method in 170 children with NSCL/P and 100 healthy controls of Uyghur and Han population.Results:Rs1801133 TT and T allele was statistically difference between 2 nationalities(P <0.05),Rs1801133 CT and CT +TT genotypes in total case group and control group were sta-tistically different(P <0.05);Rs1801131 and rs1801133 conjoint analysis showed that between the 2 nationalities and between case and control groups of total population were statistically different(P <0.05);rs1801131 genotype between 2 nationalities or total cases and controls were not statistically different(P >0.05).Conclusion:Rs1801133 TT and T allele in Han nationality are more likely to suffer from NSCL/P than in Uyghur,rs1801133 CT and CT +TT genotypes are protective factors.Rs1801131AC and rs1801133CC conjoint is relevant to NSCL/P,and the risk in Uyghur is higher than in Han.MTHFR rs1801131 gene polymorphism may not be relat-ed with NSCL/P in Uyghur or Han.

Objective To construct a large animal model of ischemic heart disease induced by acute myocardial infarction (AMI) . Methods Male Diannan Mini-pigs were selected (n=8), weight 20 ± 4 Kg. After general anesthesia and endotracheal intubation, blood pressure and electrocardiograph were monitored. Parasternal incision was taken and thoracotomyv was performed at 4th-to-5th intercostalgap. Pericardium was opened and left anterior descending artery was ligated. Echocardiography was performed at baseline, postoperative 28 and 60 day. Euthanasia and heart explanted was conducted at 60 day of experimental pig. After gross examination of the heart, the histological examination was used to assess myocardial infarction by using H&E staining. Results All of the pigs were presented with ventricular arrhythmias in varying degrees after ligation of the left anterior descending artery, of whom 2 died of refractory ventricular fibrillation, the mortality was 25%. Echocardiography assessment showed the loss left ventricular function, the thinning of left ventricular apical and the enlargement of left ventricule. Histological examination revealed that myocardial fibrosis and fibrous scar were formed in myocardial infarction area. Conclusion The ligation of left anterior descending artery through thoracotomy under direct vision is a reliable strategy for construction of AMI porcine model and the experimental porcine can develop ischemic cardiac dysfunction progressively.

BACKGROUND:The decel ularized porcine smal intestinal submucosa is a kind of bioactive extracel ular matrix, which is mainly composed of col agen, glycoprotein, proteoglycan and rich in col agen, glycosaminoglycan and various growth factors, and these components play an important role in promoting the differentiation and proliferation of tissue cel s. OBJECTIVE:To prepare the injectable smal intestinal submucosa and to investigate its co-culture with rat adipose-derived mesenchymal stem cel s in vitro. METHODS:The injectable smal intestinal submucosa and rat adipose-derived stem cel s were prepared. Cel counting kit-8 test for cel proliferation:Passage 3 adipose-derived stem cel s were seeded onto the injectable smal intestinal submucosa (experimental group) and cel s cultured under normal condition as control group. The cel proliferation was observed at 1, 3, 5 and 7 days of incubation. Live/dead staining test for the survival of cel s:Passage 3 adipose-derived stem cel s were respectively cultured in the injectable smal intestinal submucosa extracts (experimental group) and complete culture medium (control group). Cel survival was determined at 1, 3, 5 and 7 days of culture. RESULTS AND CONCLUSION:Scanning electron microscope oval and strip adipose-derived stem cel s adhered onto the material. The absorbance values in the experimental group were higher than those in the control group at 1 and 5 days of incubation (P<0.05). Cel survival:The number of cel s appeared to be in a rising trend with time in both two groups;after 1-day co-culture, al cel s in the two groups survived. Then dead cel s appeared in both two groups, showing no significant difference. These results show that the injectable smal intestinal submucosa exhibits a good cytocompatibility.

Objective: Mental disorders of the elderly population in China deserve attention. Social health is significantly associated with depression. This study aimed to evaluate the rate of depressive symptoms and to test the relationships between social health and depressive symptoms among a large sample of community-dwelling elderly adults. Methods: We conducted a cross-sectional study among community-dwelling adults aged 60 years or above in Zhejiang Province, China. Face-to-face interviews were used to complete a structured questionnaire for all participants. We used the Social Health Scale for the Elderly (SHSE) to evaluate social health status and used the short form of the Geriatric Depression Scale to evaluate depressive symptoms. Multivariate logistic regression was used to evaluate the association between social health status and depressive symptoms. Results: Of the total of 3757 participants included, 1887 (50.23%) were female, and the mean±standard deviation (SD) age was (70.0±8.3) years. The rate of depressive symptoms was 25.92%. The social health score was higher in non-depressed participants than in depressed participants (raw score 50.7 vs. 48.3, P < 0.001). Participants with “moderate” or “good” social health had a significantly lower risk of depressive symptoms than those with “poor” social health (odds ratio (OR)=0.55, 95% confidence interval (CI): 0.46-0.66 for moderate social health; OR=0.45, 95% CI: 0.35-0.60 for good social health). The association between social health and depressive symptoms was consistent across several subgroups. Conclusions: Social health is significantly inversely associated with depressive symptoms. The SHSE may serve as an efficient screener to identify those elderly adults with social health deficits, but systematic assessment to guide intervention merits further investigation.

Objective To evaluate the effectiveness of MSCT in the diagnosis of superior sinus venosus atrial septal defect.Methods The MSCT features of superior sinus venosus atrial septal defect in twenty cases were evaluated retrospectively.The following data were recorded:the size and location of sinus venosus atrial septal defect,the anatomy of pulmonary vein,including number of anomalously draining pulmonary veins and their site of drainage,and associated anomalies.Results In all patients,the superior sinus venosus atrial septal defect locates in the extraseptal wall,which normally separates the right upper pulmonary vein from superior vena cava(SVC).And anomalous connection of right upper pulmonary venous and SVC was identified in all the patients.The mean value of the defect diameter was ( 17.1±5.8) mm.Left superior vena cava was identified in 3 patients.In an elderly patient,left anterior descending branch of coronary artery presented significant stenosis.And in another elderly patient with large atrial septal defect,severe pulmonary hypertension was identified by cardiac catheterization.MSCT findings of superior sinus venosus atrial septal defect in 6 cases were finally confirmed by surgical operation.Conclusions Contrastenhanced MSCT was a useful technique for the diagnosis of superior sinus venosus atrial septal defect,which accurately displayed the anatomical characteristics of the associated malformations for preoperative evaluation.

Background and purpose: Osteopontin (OPN) is a glycophosphoprotein that is expressed by numerous human cancer cells. The function of OPN in skeletal modeling and remodeling, bone resorption, angiogenesis and tumor cell metastasis and progression through binding with integrin and CD44 receptors were studied. Our purpose of the study was to detect the level of osteopontin(OPN) and CD44 variant isoforms(CD44v6) in multiple myeloma (MM) patients, and to explore the relationship between OPN and CD44v6 with the progress of MM. Methods: 32 MM patients were admitted to our hospital from Sep. 2007 to Dec. 2008. The patients were divided into two groups, group A (untreated and relapsed MM patients) and B (stable MM patients), and the control group including 15 subjects were the benign anemia patients or healthy people who suffered bone fracture. Bone marrow mononuclear cells (MNCs) and bone marrow stromal cells (BMSCs) from MM patients and subjects were investigated as potential OPN and CD44v6 producers. The level of OPN and CD44v6 of the conditioned media from MM patients and subjects were analyzed by ELISA. Results: The OPN level in group A (19 cases) was significantly higher than group B (13 cases) and control group (P<0.05). The CD44v6 level of 14 patients in group A was significantly higher than that of 10 cases in group B and control group (P<0.05); The OPN level of MM patients was correlated with the level of CD44v6 (r=0.52, P=0.000), the percentage of plasma cells in the bone marrow (r=0.74, P=0.000), M protein (r=0.53, P=0.014), and β2-microglubin (r=0.62, P=0.002). Conclusion: The increase of OPN and CD44v6 is associated with progress and pathogenesis of MM,and may be involved with tumor burden, stage and tumor invasion.
