Objective To investigate the effect of laparoscopy-assisted partial small bowel resection combined with open tension-free hernioplasty on patients with strangulated inguinal hernia. Methods 98 patients with strangulated inguinal hernia from January 2013 to December 2015 in our hospital were enrolled in the study and divided into the minimally invasive group (n= 41, laparoscopy-assisted partial small bowel resection combined with open tension-free hernioplasty) and laparotomy group (n=57, open partial small bowel resection combined with Bassini repair) ac﹣cording to the operation mode. Preoperative baseline data, operation time, postoperative complications, postoperative hospital stay, survival status and recurrence rate were compared between two groups. Results There were no signifi﹣cant differences in preoperative baseline data between the two groups (P> 0.05). The incidence of postoperative chronic pain and recurrence in the minimally invasive group were significantly lower than that in laparotomy group (P< 0.05). There were no significant differences in operation time, incidence of incision infection, inguinal bruising or hematoma, postoperative hospital stay, perioperative mortality between the two groups (P>0.05). Conclusions For patients with strangulated inguinal hernia, laparoscopy-assisted partial small bowel resection combined with open tension-free hernioplasty could not only make full use of advantages of tension-free repair patch, but also avoid pol﹣lution of the bowel resection to patch, which can reduce the risk of infection and recurrence, it is worthy of clinical application.

Objective To compare the effects of different blood purification methods on blood lipid metabo-lism and malnutrition in maintenance hemodialysis patients. Methods From January 2015 to May 2017,80 patients with maintenance hemodialysis admitted in Wuyi Traditional Chinese Medicine Hospital of Jiangmen were selected. The patients were divided into study group and control group according to the random number table method,with 40 cases in each group. The control group was treated with hemodialysis,the study group was treated with hemoperfusion combined with hemodialysis,all patients were treated for 12 weeks. The levels of total cholesterol (TC),triglyceride (TG),low density lipoprotein cholesterol(LDL - C),hemoglobin(Hb),total protein(TP),albumin(Alb),transferrin (TRF),interleukin 6(IL - 6) and tumor necrosis factor α(TNF - α) were compared before and after treatment. The incidence of complications at the same time were observed. Results After treatment,the levels of TC,TG,LDL - C in the study group were (4. 39 ± 0. 91) mmol/ L,(1. 41 ± 0. 20) mmol/ L,(2. 55 ± 0. 31) mmol/ L,respectively,which were lower than those in the control group [(6. 21 ± 0. 55)mmol/ L,(1. 83 ± 0. 50)mmol/ L,(3. 05 ± 0. 63)mmol/ L] (t = 10. 825,4. 933,4. 504,all P < 0. 05). After treatment,the levels of Hb,TP,Alb,TRF in the study group were (106. 83 ± 22. 05)g/ L,(62. 14 ± 22. 50)g/ L,(38. 30 ± 6. 48) g/ L,(19. 70 ± 2. 20) g/ L,respectively,which were higher than those in the control group [(94. 28 ± 13. 17)g/ L,(52. 38 ± 12. 37)g/ L,(33. 17 ± 6. 80)g/ L,(16. 24 ± 1. 54)g/ L] (t = 3. 090,2. 404,3. 454,8. 146,all P < 0. 05). After treatment,the levels of IL - 6,TNF - α in the study group were (124. 52 ± 107. 23)ng/ L,(72. 13 ± 12. 55)ng/ L,respectively,which were lower than those in the control group [(294. 14 ± 108. 92) ng/ L, (112. 45 ± 21. 29) ng/ L] ( t = 7. 019,10. 318, all P < 0. 05). The incidence rate of complications of the study group was 5. 00％ ,which was lower than 22. 50％ of the control group (χ2 = 5. 165,P < 0. 05). Conclusion Hemoperfusion combined with hemodialysis in maintenance hemodialysis patients can improve their blood lipid metabolism and malnutrition,reduce inflammation and the risk of complications.

Birth cohort is an important observational study which can continuously and dynamically collect the exposure changes and health outcomes from gametophyte development to adolescence and even old age. However, because of its complex design and difficult implementation, how to construct birth cohort with high quality and high efficiency is the main difficulty faced by epidemiologists at home and abroad. In 2016, China National Birth Cohort was officially launched. The network and information technology were used to explore, and a set of "cloud-based information platform" was established to support this queue construction, containing 16 units in China. After four years of development, the platform has formed a complete set of programs about the construction of cohort information platform, which including recruitment and follow-up management of participants, real-time data interaction, queue quality control, multi-level authority management and function division. The relevant design framework and functional elements provide the references to the future information construction of large-scale birth cohort and even population-based research in China.

Objective: To understand the viral etiology of a clustered case of human infection outbreak in the middle school of Huai’an city. Methods: Nasopharyngeal swab samples from patients were collected and rapidly detected by Real-time RT-PCR and the target virus isolated in cells. Furthermore, HA1 segments of target virus were amplified by RT-PCR and sequenced. The genetic and phylogenetic analysis based on HA1 genes was computed. Results: Influenza A(H1N1)pdm09 viral nucleic acid in 11 nasopharyngeal swab samples from patients in the outbreak were positive. Compared to the vaccine strains A/California/07/2009, the Huai’an isolates, nucleotide identity was 97.7%-98.1%, and amino acid identity was 96.6%-97.4%. Phylogenetic analysis of HA1 segment sequences indicated that the Huai’an strains from the outbreak were related closely to the viruses isolated in the year of 2014. Sequence analysis indicated that the Huai’an isolates had no amino acid substitution in the receptor binding sites and glycosylation sites, while in the Ca1 of antigenic determinant of HA1 the Huai’an isolates had an amino acid substitution of S for T at 220. Conclusions The pathogen of the clustered case of human infection was Influenza A(H1N1)pdm09 virus. Though the Huai’an isolates had one animo acid substitution in the Ca1 of antigenic determinant, the antigenicity characteristic remained unchanged.
