Objective To understand the status of knowledge awareness rates and influencing factors of clonorchiasis among the residents in 4 counties(cities)of Hunan Province,so as to provide the references for formulating the prevention and control strategy of clonorchiasis in the province. Methods A total of 1224 subjects were selected by the multi-stage cluster sampling method and investigated with questionnaires and face-to-face interviews. Results The clonorchiasis knowledge awareness rates of the residents were 15.67% in Yongzhou City,9.94% in Yueyang City,13.25% in Wangcheng County,and 21.96% in Tongd-ao County,respectively. In the whole province,the clonorchiasis knowledge awareness rates of the residents were 44.67%, 56.43%,60.95%,and 42.46% in the etiology,clinical manifestations,epidemiological characteristics and daily prevention,re-spectively. The logistic regression showed that the influencing factors of clonorchiasis knowledge awareness rates were the daily dining place,whether or not having the medical personnel in the family,the degree of attention to the relevant news reports, and the history of parasitic diseases. Conclusions The level of clonorchiasis than that in other areas,but the overall level of clonorchiasis knowledge awareness of the residents in Hunan Province is not high. Therefore,the relevant authority should strengthen the health education in clonorchiasis prevention knowledge including personal daily food hygienic knowledge. knowl-edge awareness rate of the residents in the west-southern areas of Hunan Province is higher

OBJECTIVETo explore the clinical effect of talar neck fractures treated by open reduction and internal fixation with screws.

METHODSAmong 28 cases in the study, 20 cases were males and 8 cases were female. The age ranged from 22 to 72 years with an average of 38 years. Based on the Hawkins classification,there were 6 cases of type I,18 of type I and 4 of type II. They were treated by open reduction and internal fixation with screws.

RESULTSTwenty-eight cases were followed up for 1 to 7 years(mean 2.8 years). The evaluation of the results by Hawkins functional rating scale revealed excellent in 14 cases,good in 9 cases, fair in 3 cases and poor in 2 cases. The excellent and good rate were 83.2%. Osteonecrosis occurred in 5 cases with 3 of type II and 2 of type III fractures. Two of 3 cases with talar displacement were found with osteonecrosis or painful arthritis. The subtalar arthritis occurred in 6 cases, 3 of which were associated with ankle arthritis. Two cases underwent arthrodesis because of painful arthritis of the subtalar joint or osteonecrosis of the talar body. Wound infection and anteromedial skin necrosis of the ankle were not found.

CONCLUSIONTreatment of talar neck fractures could obtain satisfactory clinical results through open reduction and internal fixation with screws. Protection of the residual blood supply, anatomically reduction and stable fixation are essential for successful treatment of talar neck fractures.

Objective To analyze the clinical and epidemiological characteristics of human avian influenza A (H7N9 ) epidemic in Jiaxing City,and to provide scientific basis for the control and prevention of the disease.Methods The epidemiological and clinical information of 15 cases of human infection with avian influenza A (H7N9)reported from April, 2013 to May,2015 were collected.Sample of patients and external environmental samples of suspected exposure were collected and detected by real-time PCR.The epidemic distribution and clinical characteristics were analyzed.Results Fifteen cases of human infection with H7N9 were confirmed from April,2013 to May,2015,including 11 cases of death (77.33%).The confirmed cases mostly reported in winter and spring,and 9 confirmed cases were over 60 years,and male case proportion was higher than women (1.5∶1 ).Most of cases (66.67%)were sporadic and occurred in rural areas,but no epidemiological association was observed among the cases.Fever (100%),cough (66.67%),and wheezing and tightness in chest (33.33%)were common initial symptoms.The chest imaging examination of patients showed ground glass opacity and patchy consolidation,and 7 cases had simple pleural effusion.Twelve of confirmed cases had other chronic diseases.Eleven cases of death had appeared multiple medical comorbidities,such as respiratory failure (6/1 1 ),pulmonary embolism (4/1 1 ),multiple systemic organ failure (3/1 1 ),and heart cerebrovascular embolization (2/11).Twelve cases had been exposed to the live poultry markets where the positive rate of novel influenza A (H7N9) virus in environmental specimens was 7.69%(25/325).One of the 252 close contacts to confirmed cases appeared mild flu-like symptoms.No positive result related to novel influenza A (H7N9)virus nucleic acid was detected from each close contact's throat swabs.Conclusion Human infections with avian influenza A (H7N9)virus showed obvious seasonal distribution in Jiaxing.Elderly men,especially those with chronic diseases were the high risk people of human infection with H7N9 avian influenza.The infection might be associated with the exposure to live birds.Standard management of live poultry markets is the key measure in preventing and controlling H7N9 virus infection among population.

OBJECTIVETo compare two techniques of the transarticular screw placement in the lower cervical spine, and to suggest and confirm a new technique of the placement.

METHODSThe techniques of transarticular screw placements used by Takayasu (group A) and Dalcanto (group B) were applied in eight cervical specimens. The splits of facets,the encroachment of the cervical nerve roots and transverse foramens were observed and analyzed. The numbers of transarticular screws which not gone through the facets were counted in both group A and B, respectively.

RESULTSSixty-four transarticular screws were implanted,thirty-two for group A, the same for group B. Although no splits of the facets were seen in group A, two transarticular screws did not go through the facets. There were ten splits of facets in group B, in which seven involved the inferior border of the inferior facets and three for the lateral border. No superior facets were found to be broken both in group A and B. Eight screws encroached the transverse foramens in group A and none in group B. Eleven of anterior branch and eight of posterior branch of lower cervical nerve roots were involved in group A, two and nine respectively in group B.

CONCLUSIONThere are high risk of injury of anterior branch of cervical nerve root and vertebral artery if the screws are too long and the Takayasu's technique is used. However, the rate of facet split is high if the Dalcanto's technique is applied.

Objective To investigate the awareness rate,treatment rate and control rate of mineral and bone disorder in patients with moderate or advanced stage chronic kidney disease (CKD). Methods The awareness rate,treatment rate and control rate of mineral and bone disorder were evaluated based on a questionnaire and related laboratory examinations in 503 CKD stage 3 to 5 patients. Results The awareness rate of mineral and bone disorder in patients with moderate or advanced stage CKD was highest in hemodialysis patients,moderate in peritoneal dialysis patients and lowest in non-dialyzed patients (all P ＜0.01).The total scores of the questionnaire were lowest in non-dialyzed patients [6 (5,8)] and were significantly higher in peritoneal dialysis [11 (9,12)] and hemodialysis patients [13 (11,15)] (P＜0.01).The extent of awareness was negatively correlated with age (r=-0.11,P＜0.05),and positively correlated with educational background (r=0.226,P＜0.01),duration of CKD (r=0.597,P＜0.01) and duration of dialysis (r=0.366,P＜0.01).The source of knowledge was mainly from publicity and education made by medical staff,which accounted for 94.0％,79.5％ and 69.4％ respectively in nondialyzed,peritoneal dialysis and hemodialysis patients.The treatment rate was significantly higher in peritoneal dialysis (88.6％) and hemodialysis patients (96.9％) than that in non-dialyzed patients (58.2％) (all P＜0.01).According to K/DOQI guideline,the control rate of serum calcium,phosphorus,calcium and phosphorus product and parathyroid hormone (PTH) were much better in non-dialyzed patients as compared to dialyzed ones.The percentage of number of lab indicators meeting the standard was significantly higher in non-dialyzed patients as compared to dialyzed ones (P＜0.01).According to KDIGO guideline,the control rate of serum phosphorus was significantly lower in hemodialysis patients (23.6％) than that in peritoneal dialysis (36.9％) and non-dialyzed patients (46.7％) (P＜0.01). Conclusions In non-dialyzed patients with moderate or advanced stage CKD,the awareness rate and treatment rate of mineral and bone disorder are relatively low,and the control rate is relatively high.Whereas in dialyzed patients,the awareness rate and treatment rate are relatively high,and the control rate is relatively low.

OBJECTIVETo investigate the effect of catenin p120 (p120ctn) translocation on the malignant features of hepatocellular carcinoma and its interrelation with beta-catenin in E-cadherin-mediated cell signaling.

METHODSExpression and translocation of p120ctn, tyrosine phosphorylation, and its binding capacity to E-cadherin were detected by DNA transfection, immunoblotting and immunoprecipitation. Cellular localization of p120ctn and beta-catenin was detected by immunofluorescent microscopy. Cell adhesion, cell migration and cell proliferation were also studied.

RESULTSExpression of p120ctn increased after cells transfected with p120ctn isoform 3A, and it was located mainly at cell-cell contact region. Its binding to E-cadherin was enhanced. After EGF stimulation, tyrosine phosphorylation of p120ctn was increased, membrane expression of p120ctn and beta-catenin was decreased while cytosol expression was increased. It was translocated into the nucleus, cell adhesiveness was increased but mobility decreased. With over-expression of p120ctn, beta-catenin was recruited by nucleus export. Cell proliferation was reduced but it was increased after EGF treatment.

CONCLUSIONp120tn plays an important role in cell adhesion, migration and proliferation of hepatocellular carcinoma, and its tyrosine phosphorylation might contribute to this mechanism. There might be a competitive relationship between p120ctn and beta-catenin.
