ABSTRACT

OBJECTIVE: This study aims to explore the risk factors for stone remnants and recurrence after lateral decubitus percutaneous nephrolithotomy (PCNL), providing insights to enhance the stone-free rate and reduce the stone recurrence rate. PATIENTS AND METHODS: A retrospective analysis was conducted on 356 patients with renal or upper ureteral stones who underwent lateral decubitus PCNL from January 2015 to August 2022. Among them, 271 patients had complete clinical and follow-up data. General clinical information, perioperative data, and follow-up data were collected. Univariate and multivariate logistic regression analyses were performed to identify risk factors for stone remnants and recurrence after lateral decubitus PCNL. RESULTS: The stone-free rate after lateral decubitus PCNL was 88.6% (195/271), and the stone recurrence rate within three years was 28.1% (76/271). Stone size (p<0.001) and stone co-infection (p=0.047) were identified as independent risk factors for stone remnants after lateral decubitus PCNL. Multiple stones (p=0.003) were an independent risk factor for stone recurrence after lateral decubitus PCNL. CONCLUSIONS: Stone size and stone co-infection are independent risk factors for stone remnants after lateral decubitus PCNL. Multiple stones are an independent risk factor for stone recurrence after lateral decubitus PCNL.

ABSTRACT

On May 13, 2022, World Health Organization(WHO) Position Paper on Influenza Vaccine (2022 edition) was published. This position paper updates information on influenza epidemiology, high risk population, the impact of immunization on disease, influenza vaccines and effectiveness and safety, and propose WHO's position and recommendation that all countries should consider implementing seasonal influenza vaccine immunization programmes to prepare for an influenza pandemic. In addition, it proposes that the influenza surveillance platform can be integrated with the surveillance of other respiratory viruses, such as SARS-CoV-2 and Respiratory Syncytial Virus. This position paper has some implications for the prevention and control of influenza and other respiratory infectious diseases in China: (1) Optimize influenza vaccine policies to facilitate the implementation of immunization services; (2) Influenza prevention and control should from the perspective of Population Medicine focus on the individual and community to integrate with "Promotion, Prevention, Diagnosis, Control, Treatment, Rehabilitation"; (3) Incorporate prevention and control of other respiratory infectious diseases such as influenza, COVID-19, respiratory syncytial virus and adenovirus, and intelligently monitor by integrating multi-channel data to achieve the goal of co-prevention and control of multiple diseases.

ABSTRACT

We previously demonstrated in rats that noninvasive delayed limb ischemic preconditioning (LIPC) induced by three cycles of 5-min occlusion and 5-min reperfusion of the left hind limb per day for three days confers the same cardioprotective effect as local ischemic preconditioning of the heart, but the mechanism has not been studied in depth. The aim of this project was to test the hypothesis that delayed LIPC enhances myocardial antioxidative ability during ischemia-reperfusion by a mitochondrial K(ATP) channel (mito K(ATP))-dependent mechanism. Rats were randomized to five groups: ischemia-reperfusion (IR)-control group, myocardial ischemic preconditioning (MIPC) group, LIPC group, IR-5HD group and LIPC-5HD group. The MIPC group underwent local ischemic preconditioning induced by three cycles of 5-min occlusion and 5-min reperfusion of the left anterior descending coronary arteries. The LIPC and LIPC-5HD groups underwent LIPC induced by three cycles of 5-min occlusion and 5-min reperfusion of the left hind limb using a modified blood pressure aerocyst per day for three days. All rats were subjected to myocardial ischemia-reperfusion injury. The IR-5HD and LIPC-5HD groups received the mito K(ATP) channel blocker 5-hydroxydecanoate Na (5-HD) before and during the myocardial ischemia-reperfusion injury. Compared with the IR-control group, both the LIPC and MIPC groups showed an amelioration of ventricular arrhythmia, reduced myocardial infarct size, increased activities of total superoxide dismutase, manganese-superoxide dismutase (Mn-SOD) and glutathione peroxidase, increased expression of Mn-SOD mRNA and decreased xanthine oxidase activity and malondialdehyde concentration. These beneficial effects of LIPC were prevented by 5-HD. In conclusion, delayed LIPC offers similar cardioprotection as local IPC. These results support the hypothesis that the activation of mito K(ATP) channels enhances myocardial antioxidative ability during ischemia-reperfusion, thereby contributing, at least in part, to the anti-arrhythmic and anti-infarct effects of delayed LIPC.

ABSTRACT

In the present paper, effects of scopolia drugs (scopolamine, anisodine, anisodamine) on experimental gastric mucosal lesion models in rats were investigated. Scopolia drugs were found to be effective anti-ulcer agents in three experimental gastric ulcer models (i.e. cold-restraint stress induced ulcer, indomethacin induced ulcer and acetic acid induced chronic ulcer) in rats in a dose dependent manner. Biochemical analysis of gastric juice and blood showed that scopolia drugs could inhibit gastric acid secretion and pepsin activity, increase gastric barrier mucus and concentration of serum gastrin, suggesting that these actions may contribute to its anti-ulcer effect.
