Familial adenomatous polyposis (FAP) is one of the most common hereditary colorectal cancers. Its intestinal and extra-intestinal manifestations are correlated with mutation sties of the APC gene. Potential gene modulation sites in patients who have typical clinical manifestations but with unidentified APC mutations are also discussed, which included MUTYH gene, AXIN gene and certain epigenetic changes. With the generalization of Precision Medicine, to offer individualized treatment and surveillance strategy based on the genotype-phenotype correlation will be of great value for FAP patients. This review focuses on the research advance in genotype - phenotype correlation studies of FAP patients.

Objective : To understand the status of rural environmental sanitation and summer diarrhea among rural residents in Zhejiang Province,and to provide evidence for improvement of rural environmental sanitation and prevention and control of summer diarrhea. Methods : The stratified random sampling method was used. Five or six counties each were selected from the east,middle and west of Zhejiang Province;five townships（excluded Chengguan Town）were selected from each selected county;four villages were selected as field survey points from each township;five households were selected from each survey point;one family member（householder or housewife）was selected from each selected household. The information about the environmental sanitation status and prevalence of summer diarrhea were obtained by literature review,interviews,questionnaire suvey,field investigation and laboratory tests. Logistic regression model was used to analyze the influencing factors for occurrence of summer diarrhea among rural residents. Results : There were 2 000 households surveyed. In the past two weeks,108 households had families with diarrhea and the prevalence of diarrhea was 5.40%. A total of 1 828 households disposed the household waste in the garbage bins or pools,accounting for 91.40%. There were 1 926 households with organized sewage discharge,accounting for 96.30%. There were 768 households with nymphs found in the kitchen,accounting for 38.40%;404 households with live egg sheaths found,accounting for 20.20%;592 households with cockroach traces found,accounting for 29.60%;564 households with rat traces found,accounting for 28.20%;and 1 206 households with flies found,accounted for 60.30%. There were 1 314 households with disease vectors around the house,accounting for 65.70%. There were 1 944 household with sanitary toilets,accounting for 97.20%. A total of 1 915 households had habits of drinking boiled water,accounting for 96.57%. The results of multivariate logistic regression analysis showed that rat traces found in the kitchen（OR=2.026,95%CI: 1.362-3.013）were a risk factor for summer diarrhea in rural residents,while drinking boiled water（OR=0.272,95%CI: 0.091-0.811）was a protective factor. Conclusion The sanitary environment and family health habits of rural residents were related to the prevalence of diarrhea in summer. Paying attention to kitchen hygiene and drinking boiled water could prevent summer diarrhea.

OBJECTIVETo compare the efficacy between left radial approach (LRA) and right radial approach (RRA) for coronary angiography (CAG).

METHODSThe following databases were searched, including PubMed, Embase, Web of science, Cochrane Library, CBM, VIP, Wanfang databases and CNKI, from creation of database to January 2013. Two reviewers extracted data independently, according to inclusive criteria, exclusion criteria and methods of Cochrane Collaboration. Statistical analysis was performed using Review Manager Software (RevMan 5.1).

RESULTSEleven trials with 5 442 patients were included in the systematic review. The results of meta-analysis showed that when compared with RRA, LRA did not increase the failure rate of the procedures (OR = 1.04, 95%CI 0.80-1.35, P > 0.05) and amount of contrast medium (mean difference = 2.39, 95%CI -0.30-5.08), P > 0.05). However, LRA was superior to RRA in reducing fluoroscopy time (standardized mean difference = 0.15, 95%CI 0.06-0.24, P < 0.01). In addition, the incidence of severe tortuosity of subclavian artery was significantly lower with LRA (OR = 4.65, 95%CI 1.98-10.88, P < 0.01).

CONCLUSIONSBased on the current evidence, LRA shares similar safety with RRA for CAG and is superior to RRA in certain respects. LRA can thus be used either as an alternative approach or routine approach for CAG.

Objective To investigate the relationship of the neutrophil/lymphocyte ratio (NLR) on admission and angiographic no-reflow phenomenon in patients with ST-segment elevation myocardial infarction (STEMI) who had undergone primary percutaneous coronary intervention (PCI).Methods 232 patients who had undergone PCI between 2010 and 2013,were included and divided into two groups based upon the thrombolysis in myocardial infarction (TIMI) flow gradings.No-reflow was defined as post-PCI TIMI Grade 0,1 and 2 flows (group Ⅰ).Normal-flow was defined as TIMI 3 flow (group Ⅱ).Receiver operating characteristic curve (ROC) analysis was used to identify the predictive effect of NLR on no-reflow phenomenon.Relationship of NLR and no-reflow was assessed by multivariate logistic regression.All statistical calculations and analyses were performed using SPSS 11.0.Results NLR was significantly higher in group Ⅰ (n=45) compared with group Ⅱ (n=187) [4.1 (2.4-6.5) vs.2.4 (1.7-3.8),P=0.001].In ROC analysis,NLR＞3.2 predicted no reflow with 80％ sensitivity and 73％ specificity.Patients with elevated NLR had a higher incidence of no-reflow phenomenon than those with non-elevated NLR (34.8％ vs.9.3％,P＜0.001).Also,NLR (＞3.2) was an independent predictor of no-reflow development [odds ratio 3.70,95％ confidence interval (1.39-9.80),P=0.009].Conclusion NLR was an independent predicator for no-reflow development in STEMI patients who had undergone PCI.This simple and low-cost parameter could provide useful information for the early risk evaluation on these patients.

Objective: To learn the disinfection effect and its influencing factors of drinking water in rural areas of Zhejiang Province,so as to provide scientific basis for the control of microbial pollution in drinking water and prevention of waterborne diseases. Methods: A total of 5 299 samples from 879 rural water plants Zhejiang Province were collected by stratified sampling method in 2017. The disinfection effect of water samples was assessed quality according to GB 5749-2006 Hygienic Standards for Drinking Water. Logistic regression models were used to analyze the influencing factors for disinfection effect of rural drinking water. Results: There were 540 rural water plants in Zhejiang Province adopting routine process for water purification,accounting for 61.43%;771 ones using surface water,accounting for 87.72%. About 4 458 samples（84.13%）were disinfected and the qualified rate was 86.05%,22.32% of which were disinfected by chlorine dioxide and the qualified rate was 100.00%. The results of multivariate logistic regression analysis showed that scale of water plant,disinfectant residue,use frequency of disinfection equipment,disinfection,season and source water turbidity were the influencing factors for the disinfection effect of rural drinking water（P<0.05）;disinfection,disinfectant residue,use frequency of disinfection equipment and source water turbidity were the influencing factors for the disinfection effect of finished water（P<0.05）;disinfection,disinfectant residue,use frequency of disinfection equipment,source water turbidity and scale of water plant were the influencing factors for the disinfection effect of tap water（P<0.05）;disinfectant residue,use frequency of disinfection equipment,source water turbidity and scale of water plant were the influencing factors forthe disinfection effect of surface water（P<0.05）;disinfectant residue,use frequency of disinfection equipment,source water turbidity and pH were the influencing factors for the disinfection effect of groundwater（P<0.05）. Conclusion The disinfection effect of drinking water in rural areas of Zhejiang Province is associated with source water quality,scale of plants,water purification technique and so on. The disinfection process should be improved,the management of water plants should be strengthened to reduce the risk of microbial contamination.

OBJECTIVE：To unscramble the Notice on Standardizing the Allocation and Use of Licensed Pharmacists in Drug Retail Enterprises （called Notice for short ）and related document ，and to give some suggestions to provide reference for the industry and policy decision departments. METHODS ：The background and content of Notice were described briefly ；the problemsexisting in the corresponding provincial differentiated allocation policy and the difficulties existing in the implementation were analyzed to give some relevant suggestions. RESULTS & CONCLUSIONS ：The main contents of Notice contained adhering to the policy of licensed pharmacists ，steadily improving the allocation level of licensed pharmacists ，refining and implementing the allocation requirements ，and strengthening the implementation of supervision and inspection responsibilities ；giving full play to the role of licensed pharmacists and continuously strengthening the team building. At present ，drug administrations of many provinces in China have issued specific policies on the differentiated allocation of licensed pharmacists and pharmaceutical technicians ，which are mainly divided into four schemes. The author believes that the classification method of drug retail enterprises implemented in Shandong and Guangdong provinces are the most scientific. The implementation of differentiated allocation of pharmacists with health（pharmacy）professional title in drug retail enterprises can alleviate the problem of insufficient licensed pharmacists to a certain extent ，but the disadvantage is that it can not achieve accurate registration and control as well as the management of licensed pharmacists ，which is easy to produce policy gaps ；after the “affiliation licensed pharmacist ’s certificate ”phenomenon， the“certificate affiliation of pharmacist with health （pharmacy）professional title ”phenomenon appeared. It is suggested that the provincial drug supervision and administration departments should try the differentiated allocation scheme of hierarchical management；learn from the management experience of licensed pharmacists and pharmaceutical technicians in Guangdong province， develop relevant platforms to manage the information of pharmaceutical technicians uniformly ； strengthen the communication and interaction with the health and human resource security department as well as the mutual promotion mechanism of personnel information screening ，so as to solve the core bottleneck of licensed pharmacists ’quality.

BACKGROUND: Surgical site infection is one of the common postoperative complications of thoracic surgery, and its harm is related to infection degree and location. Light causes local pain, prolonged hospitalization and increased cost. Severe infection can lead to severe infection, even septic shock and life-threatening. Therefore, proper treatment of incision infection can help to promote recovery, reduce the burden of disease and lay a good foundation for further treatment. The traditional surgical treatment of wound infection includes thorough drainage, intensive dressing change and antibiotic use. There are many shortcomings such as long treatment process, ineffective treatment effect and so on. The experience of using vacuum sealing drainage (VSD) in 6 cases of postoperative infection patients in our department is summarized in order to improve the traditional treatment of postoperative infection in patients after thoracic surgery. METHODS: The clinical data of patients with postoperative incision infection or fistula after thoracic surgery in our department were reviewed and summarized. 6 patients treated with VSD material for postoperative infection. The process and final clinical results of them were summarized and discussed. RESULTS: In this study, fever and wound exudation disappeared within 6 h-10 h after VSD use, 5 cases of wound infection were obviously improved, the secretion disappeared and the granulation tissue grew well at the cutting edge of the operation, the second stage operation was performed to close the chest and skin. One patient was seriously infected, and the secretion was still more after VSD removal, reposition VSD device next time, the VSD device was removed 7 d later. The wound infection were obviously improved, the secretion disappeared and the granulation tissue grew well, close the chest and skin second stage. In all 6 patients, the symptoms were relieved, the symptoms improved and the surgical incision healed well. In 2 patients with esophageal cancer, the average operation time was 427.5 min, the average hospitalization time was 40 d, the average number of times of dressing change was 8.5, the average total cost during hospitalization was 111,893.47 yuan patients with chronic empyema, the average operation time was 192.5 min. The average hospital stay was 27.75 days, the average number of times of dressing change was 5.5, and the average total expenditure during hospitalization was 48,237.71 yuan. CONCLUSIONS VSD has a good effect on the treatment of postoperative incision infection patients in thoracic surgery. It can reduce the pain and burden of patients and ensure the quality of life of postoperative infected patients.

Objective    To evaluate the feasibility and safety of da Vinci robotic surgery for elderly patients with radical surgery of lung cancer. Methods    We retrospectively analyzed the clinical data of 59 patients aged over 70 years who underwent radical surgery of lung cancer in our hospital between 2016 and 2019. These patients were divided into two groups including a da Vinci robot group and a single-utility port video-assisted thoracoscopic surgery (VATS) group according to the patients’ selection of the treatments. There were 32 patients with 20 males and 12 females aged 73.1±2.3 years in the da Vinci robot group and 27 patients with 16 males and 11 females aged 71.2±1.3 years in the VATS group. The clinical data of the two groups were compared. Results    There was no statistical difference in surgery time between the two groups (t=–0.341, P=0.484). Compared with the VATS group, the da Vinci robot group had more number of lymph nodes dissected (t=1.635, P=0.015), less intraoperative blood loss (t=–2.569, P <0.001), less postoperative drainage amount within 3 days after surgery (t=–6.325, P=0.045), lower visual analogue scale (VAS) scores at postoperative 3rd day (t=–7.214, P=0.021). Conclusion    The da Vinci robot system is safe and efficient in the treatment for elderly patients with radical surgery of lung cancer with less trauma.

Objective     To summarize the clinical data about mediastinal lesions, then to analyze the treatment effect of da Vinci robot system in the surgical treatment of mediastinal lesions. Methods     We retrospectively analyzed the clinical data of 49 patients with mediastinal lesions in our hospital between January 2016 and October 2017. These patients were divided into two groups including a da Vinci robot group and a video-assisted thoracoscopic surgery (VATS) group according to the selection of the treatments. There were 25 patients with 14 males and 11 females at age of 56.5±17.9 years in the da Vinci group and 24 patient with 15 males and 11 females at age of 53.0±17.8 years in the VATS group.
