Objective To understand the registration situation and epidemic characteristics of tuberculosis patients in Haizhu district of guangzhou, and to provide a basis for further prevention and treatment of tuberculosis in Haizhu district. Methods The data of tuberculosis patients registered at present address in the TB information management system of Haizhu district from 2008 to 2017 were collected, and the registration data of tuberculosis patients were analyzed using descriptive epidemiological methods and relevant statistical methods. Results From 2008 to 2017, 14 384 cases of tuberculosis patients were reported in Haizhu district. The annual reported incidence rate decreased from 105.3/100,000 in 2008 to 73.1/100,000 in 2017, showing a down ward trend (χ² = 164.973, P<0.001). The relative incidence of male and female was 2:1; all age groups had morbidity, of which 25~34 years old group had the largest number of cases, accounting for 21.61% of the total number of cases; in occupational distribution, household chores and unemployed were the most, accounting for 34.48 %, followed by other (non-fixed occupations), accounting for 17.29%, retired people, accounting for 15.12%, and school students accounting for 5.52%. In terms of regional distribution, the average annual incidence rate of each street varied greatly, with the highest being 131.23/100,000 and the lowest being 66.40/100,000. The difference is statistically significant(χ²=164.973,P<0.001). Conclusion The incidence of tuberculosis in Haizhu district of Guangzhou has been decreasing year by year, but the incidence of tuberculosis in some streets is still more than 100/100,000. Male population, 25~34 years old group and low-income population (domestic and underemployed, irregular occupation, retired population) are the main population for prevention and control. Students have a large number of cases of tuberculosis, so we need to strengthen prevention, control and screening of tuberculosis in schools.

Objective To investigate the effect on intestinal mucosal barrier dysfunction (IBF) of Xuebijing injection mediated by Toll-like receptor 4 (TLR4) signal pathway in rats of severe acute pancreatitis (SAP). Methods 24 Sprague Dawley (SD) rats were randomly divided into Sham group (n=8), control group (n=8) and treatment group (n=8). The SAP model was established by retrograde injection of 4.5% sodium taurocholate into the biliopancreatic duct in control group and treatment group, while control group was injected with the same amount of saline. In treatment group, Xuebijing injection (3 mL/kg) was injected via tail vein after 3h of modeling. All rats were monitored and sacrificed after 24 hours of modeling. Samples of pancreas and intestine were collected for pathologic determination. A fluorescent RT-PCR was used to determine the expression of TLR4 and NF-κB of small intestine. The serum levels of TNF-α, IL-6, amylase (AMS) and diamine oxidase (DAO) were measured by using ELISA. All parameters of three groups were compared. Results The expression of TLR4 and NF-κB of small intestine in control group and treatment group were higher than it in control group (P<0.05), as well as the serum levels of TNF-α, IL-6, AMS and DAO (P<0.05). The expression of TLR4 and NF-κB of small intestine in treatment group were lower than it in control group (P<0.05), as well as the serum levels of TNF-α, IL-6, AMS and DAO (P<0.05). Conclusion Xuebijing injection may not only reduce the expression of TLR4 and NF-κB of small intestine, but also alleviate the inflammation reaction of small intestine by interfering with TLR4 signal pathway, which may have a protective effect on intestinal mucosal barrier in SAP rats.

Objective This study aims to investigate the effect of metformin on proliferation and migration of MIN6 cells, and to explore the underlying mechanism. Methods The viability of MIN6 cells that were treated with various metformin (1,2,5,10 and 20 mmol/L) was detected by MTT assay. The migration of MIN6 cells was determined by wound-healing assay. Meanwhile, the proteins expression of Bcl-2, Bax, caspase3 and the phosphorylation of AMPK, JNK was detected by western bolt assay. Results The cell viability and the migration of MIN6 cells were decreased when the concentration of metformin above 10 mmol/L(P<0.01). The expression of apoptosis-related protein Bax(P<0.05) and p-AMPK(P<0.05)was up-regulated, anti-apoptosis-related protein Bcl-2 was down-regulated and cleaved caspase3 (P<0.05)was increased after high metformin treatment. At the same time, the phosphorylation of JNK was down-regulated by metformin(P<0.05). Conclusion High concertration of metformin may inhibit the proliferation and migration of MIN6 cells through suppressing the activation of JNK signaling pathway.

Objective By analyzing and comparing the effects of different revascularization strategies on patients with acute myocardial infarction complicated with multi-vessel disease, to explore its clinical value.Methods Selecting the patients with acute myocardial infarction complicated with multi-vessel disease from August, 2012 to August, 2015 in our hospital (Zhaoqing No.2 People's Hospital), after each patient was successfully treated with PCI, divided them into experimental group and control group by random number table method, the experimental groups were treated with preventive emergency PCI after the onset 7-10 days, and the intervention of non-infarct-related vascular diseases were done;the control groups were treated with emergency PCI for the non-infarct-related vascular diseases according to the patient's lack of blood. Visiting them randomly for 2 years, the main cardiac adverse events, other cardiovascular events and one more emergency PCI situation in the two groups were recorded.Results A total of 450 patients completed two years of follow-up, with 226 patients in the experimental group and 224 patients in the control group. All-cause mortality (χ2=7.040,P=0.008), cardiac adverse events (P> 0.05)and incidence of heart failure (χ2=1. 527,P=0.217) were no statistically significant difference between the two groups. Compared with the control group, the incidence of angina pectoris (χ2=21.092,P<0.001), cardiologic rehospitalization (χ2=22.893,P<0.001)and one more stent treatment (χ2=17.835,P<0.001) of the experimental group was significantly lower, but the revascularization rate was higher of their related blood vessels. And when the experimental group was followed up for 2 years, the taking rate of β-blockers (χ2=7.040,P=0.008) and nitrates (χ2=63.889,P<0.001) was significantly higher.Conclusion After the patients with acute myocardial infarction complicated with multi-vessel disease were successfully treated with emergency PCI to intervene the infarct-related blood vessels, and at the same time the intervention of the non-infarct-related blood vessels were done, the recurrence of angina pectoris, stent treatment and cardiopulmonary rehospitalization was significantly reduced.
