Objective To explore the C-type fixation in the application of the catheter tunnel peritoneal dialysis. Methods One hundred and twenty patients undergoing peritoneal dialysis were selected from January to December 2014 in Xijin Hospital and were randomly divided into the control group and experiment group. The peritoneal dialysis catheters of the control group were fixed vertically at the tube orifice with surgical tape, while the peritoneal dialysis catheters of the experiment group were fixed horizontally first and then placed with a shape ofC and fixed at the tube orifice with surgical tape. The two groups were compared in terms of tunnel score, infection, tube shedding and pulling-induced stimuli. Result The tunnel score and the cases of infection rate, tube shedding and pulling-induced stimuli in the experiment group were lower and fewer than those of the control group with statistical significance (all P <0.05). Conclusion The type C fixation of tube for peritoneal dialysis can effectively reduce the incidence of infections in patients with peritoneal dialysis tunnel, reduce pulling-induced stimuli, and improve comfort of the patients.

Sentinel lymph node biopsy has been proved to be the standard treatment for early breast cancer patients with negative axillary lymph node. The study related to the tracer has become one of the hottest topics in breast cancer research. At present, the biopsy is often performed using the tracer of isotope, blue dye or both of them. However, some deifciencies of the 2 tracers restrained their applications, which resulted that the rate of the procedure is limited to only about 60% of patients in developed countries and less than 5% of patients in China and other developing countries. In recent years, a variety of new tracers have emerged, such as indocyanine green, contrast-enhanced ultra-sound using microbubbles, superparamagnetic iron oxide nanoparticles. In this article, we introduced the characteristics of these 3 substances and reviewed the related research on the new tracers. In conclusion, the new tracers are still in the preliminary stage of research, and further research is needed for clinical application.

In vitro fertilization and embryo transfer(IVF-ET) technology is one of the important means to treat infertility in recent years,although it had made remarkable progress in the field of reproductive medicine,but IVF-ET pregnancy success rate is not very ideal,the reasons that influent the success of IVF-ET include both parents donor of various unfavorable factors and stimulate ovulation itself produces all sorts of malpractices,its influence factors are complicated.In recent years,how to reduce the adverse factors affecting IVF-ET,to improve the success rate of pregnancy of IVF-ET has become the hot topics in the study of domestic clinical intervention in IVF-ET,and the domestic research shown that the quality of the follicle and endometrial environment is the key to determine the success of IVF-ET.

The paper investigates 31 foreign representative clinical knowledge base,analyzes development status including the establishment and maintenance institutions,user version control,localization application,clinical evidence resources,clinical specific content representation,evidence quality evaluation criteria and so on,summarizes revelation for domestic clinical knowledge base construction.

Gastric neuroendocrine neoplasms (G- NEN) is a type of relatively rare and heterogeneous tumors mainly derived from enterochromaffin-like cells (ECL-cells) localized in the gastric mucosa. The incidence of G-NEN has increased over the past few decades, which may contribute to factors such as improved clinical and pathological experience in diagnosing this disease, as well as increased access to endoscopy. The biological behavior, clinicalpathological features and treatment response of G-NEN are different from those of pancreatic or intestinal neuroendocrine neoplasms. The diagnosis of G-NEN mainly depends on endoscopy and pathology. Conventional imaging and somatostatin receptor imaging may help to diagnose the disease stage. Treatment requires a multidisciplinary approach that may include endoscopic resection, surgery, chemotherapy, somatostatin analogues, intervention, PRRT, etc. The present study reviews the relevant guidelines in combination of our experience and research and aims to elaborate the epidemiology, clinical classification, diagnostic modalities and treatment options.

BACKGROUND:Although increasing studies have shown that autologous bone marrow stem celltransplantation can treat myocardial infarction, but there is a lack of large-scale multi-center randomized control ed trials to il ustrate the therapeutic effectiveness of autologous bone marrow stem celltreatment for myocardial infarction. OBJECTIVE:To systematical y evaluate the improvement of heart function in patients with myocardial infarction undergoing autologous bone marrow stem celltransplantation. METHODS:Cochrane Central Register of Control ed Trials (Central), MEDLINE, EMbase, PEDro (www.pedro.org.au), OpenSIGLE, National Technical Information Service (NTIS), CNKI, VIP database (VlP), Wanfang Data and Chinese biomedical literature database (CBM) were searched for the randomized control ed trials addressing bone marrow stem celltransplantation for heart function in patients with myocardial infarction. The bibliographies of the included studies were also searched. The time span was from database establishment to November 2012. The extracted data were analyzed by RevMan5.1. RESULTS AND CONCLUSION:A total of 14 randomized control ed trials were included. Results from the meta-analysis showed that the ejection fraction and cardiac output of patients undergoing bone marrow stem celltransplantation was significantly different from those of patients without celltransplantation (WMD=5.23, 95%CI (0.73, 9.72), P<0.01;WMD=1.69, 95%CI (1.23, 2.16), P<0.000 01). Current evidence has demonstrated that bone marrow stem celltransplantation can remarkably improve the ejection fraction and cardiac output of myocardial infarction patients, which can be clinical y recommended for improvement of heart function. Due to the limitations of the included studies, more large-sample, multi-center high-quality randomized control ed trials are required to further verify the therapeutic methods and effectiveness.

Objective:To understand the level of iodine nutrition in the areas with iodine deficiency and high iodine in Anyang City of Henan Province, and to provide a basis for taking targeted prevention and treatment measures and scientific adjustment of intervention strategies.Methods:In 2019, three areas with iodine deficiency (median iodine in water < 10 μg/L) and three areas with high water iodine (median iodine in water > 100 μg/L) were selected from counties (cities and districts) in Anyang City by stratified random sampling. Children aged 8-10 and pregnant women were selected in areas with high iodine and areas with iodine deficiency, respectively. Urine samples and salt samples were collected and tested, and children's thyroids were examined by B-mode ultrasound.Results:A total of 654 salt samples were collected in iodine deficiency areas, among which non-iodized salt accounted for 1.83% (12/654). A total of 628 salt samples were collected from areas with high iodine, among which non-iodized salt accounted for 6.05% (38/628). The difference in non-iodized salt rate between the two areas was statistically significant (χ 2=15.19, P < 0.05). A total of 654 urine samples were collected from children in iodine deficiency areas, with a median of 211.15 μg/L of urinary iodine, and 628 urine samples were collected from high iodine areas, with a median of 390.50 μg/L of urinary iodine. The difference was statistically significant ( U=- 18.34, P < 0.05). A total of 300 urine samples were collected from pregnant women in iodine deficiency areas, with a median of 223.95 μg/L, and 127 urine samples were collected from pregnant women in high iodine areas, with a median of 258.00 μg/L. The difference was statistically significant ( U=- 4.07, P < 0.05). The thyroid volume of 560 children in the iodine deficient areas was detected, and the swelling rate was 1.43% (8/560). The thyroid volume of 628 children in high iodine areas was detected, and the swelling rate was 2.07% (13/628). Conclusion:The iodine nutrition level of the population in the iodine deficiency areas of Anyang City is appropriate, while the iodine nutrition level of the population in the water source high iodine areas is excessive.
