Objective To investigate the expression of PRR11 in bladder cancer tissues and its effect on proliferation and apoptosis of bladder cancer cell line T24. Methods The expression of PRR11 was detected using immunohistochemistry method in 57 specimens of bladder urothelial carcinoma and adjacent tissues. The correlations of PRR11 expression with the clinicopathological characteristics of patients with bladder urothelial carcinoma were analyzed. The mRNA and protein expression levels of PRR11 in human immortalized bladder epithelial cell lines SV-HUC-1 and human bladder cancer cell lines HTB-9, T24, J82 and UM-UC-3 were measured by qRT-PCR and Western blot. The gene expression of PRR11 in T24 cells was silenced by lentivirus shRNA. The mRNA expression level of PRR11 was detected by qRT-PCR. CCK-8 was used to detect cell proliferative activity. Cell clonality was detected by plate cloning assays. The rate of apoptosis was evaluated using flow cytometry. The protein expression levels of PRR11, Caspase-3, Bcl-2 and Bax were assessed by Western blot. Results PRR11 was highly expressed in bladder urothelial carcinoma, and its expression level was correlated with the pathological grade and T stage of the tumor. The mRNA and protein expression levels of PRR11 in HTB-9, T24, J82 and UM-UC-3 cells were higher than those in SV-HUC-1 cells (

Building a strong public health system has become an urgent task in the new era. Based on more than eight years of systematic research, we believe that five aspects need to be prioritized for a strong system. First, we should change the perspective on public health, using the word “gonggong jiankang” to replace “gonggong weisheng” and the word “gonggong jiankang tixi” to replace “gonggong weisheng tixi”, to lead the public health system development. Second, we should develop a suitable public health system and continuously improve the health capacity for governance. Third, we should make it clear that the goal of building a strong system is not far-fetched, and we need to consolidate the existing institutional advantages of China’s public health system: when encountering major problems, we can maintain a unified goal and mobilize the whole society to cooperate effectively to accomplish the goal. However, we need to make up for shortcomings one by one, especially to solve the key problem of lacking a strong coordination mechanism in daily work. Fourth, we should pursue excellence and consolidate the“suitable” mechanism proven in the process of coping with the COVID-19, so that efficient mechanisms to deal with major issues can be used in routine work, and efforts should be made to consolidate the advantages of prevention and control of infectious diseases and emergency response,so as to achieve the balanced development of regions categories and units.Finally, it is necessary to strengthen the coordination of government and research institutions, in the aspects of technological innovation, talent team building and accurate consulting services, and work together to pursue a suitable and strong system to realize the modernization of the health system and capacity for governance.

Objective: This study sought to investigate the impact of different obesity patterns on coronary microvascular function in male patients with non-obstructive coronary artery disease. Methods: We retrospectively analyzed clinical data of male patients diagnosed with suspected coronary microvascular dysfunction (CMD) in the First Hospital of Shanxi Medical University between December 2015 and August 2021. All patients underwent the one-day rest and stress 13N-ammonia positron emission tomography myocardial perfusion imaging. Overall obesity was defined by body mass index (BMI) ≥28 kg/m2 and abdominal obesity was defined by waist circumference ≥90 cm. Hyperemic myocardial blood flow (MBF)<2.3 ml·min-1·g-1 or coronary flow reserve (CFR)<2.5 were referred as CMD. All patients were grouped based on their BMI and waist circumference. MBF, CFR, the incidence of CMD, hemodynamic parameters, and cardiac function were compared among the groups. Results: A total of 136 patients were included. According to BMI and waist circumference, patients were categorized into 3 groups: control group (n=45), simple abdominal obesity group (n=53) and compound obesity group (n=38). Resting MBF did not differ between groups (F=0.02,P=0.994). Compared with the control group, hyperemic MBF was significantly lower in the simple abdominal obesity and compound obesity groups ((2.82±0.64) ml·min-1·g-1, (2.44±0.85) ml·min-1·g-1 and (2.49±0.71) ml·min-1·g-1, both P<0.05, respectively). Hyperemic MBF was comparable among the groups of patients with obesity (P=0.772). CFR was significantly lower in the simle abdominal obesity group compared with the control group (2.87±0.99 vs. 3.32±0.62,P=0.012). Compared with the control group, CFR tended to be lower in the compound obesity group (3.02±0.91 vs. 3.32±0.62,P=0.117). The incidence of CMD was significantly higher in both the simple abdominal obesity and compound obesity groups than in the control group (62.3%, 52.6% vs. 22.2%, both P<0.01, respectively). Waist circumference was an independent risk factor for male CMD (OR=1.057, 95%CI: 1.013-1.103, P=0.011). Conclusions: In male patients with non-obstructive coronary artery disease, abdominal obesity is associated with decreased coronary microvascular function. Male patients with simple abdominal obesity face the highest risk of CMD.
