Studies on specific transient receptor potential melastatin 2 (TRPM2) channel inhibitors can deepen our understanding of the pathological mechanism of related diseases, and allow discovery of novel, effective targets and drugs for therapy. The development of TRPM2 channel inhibitors can be broadly classified into four categories with distinct characteristics: reutilization and structural modification of homologous ion channel modulators to produce a diverse array of TRPM2 channel inhibitors with strong inhibitory effects; TRPM2 channel inhibitors based on channel gating mechanism with high specificity; inhibitors identified through high-throughput screening with novel chemical structures; inhibitors developed from natural antioxidants with higher safety. In recent years, the application of computer-aided drug design has significantly accelerated the development of TRPM2 channel inhibitors. Several promising compounds such as ZA18, A1 and D9 have been discovered, and it is expected that more potent and selective TRPM2 channel inhibitor scaffolds will be discovered in the future. This article reviews the advances on the studies of TRPM2 channel inhibitors, aiming to provide insights for further research and clinical application of TRPM2 channel inhibitors.

Objective:To observe the effects and explore the mechanism of Tuina(Chinese therapeutic massage)static training on vascular endothelial cell dysfunction and adiponectin(APN)in obese rats. Methods:Eight of 40 Sprague-Dawley rats were randomly selected as a normal group to be fed a common diet.The remaining rats were fed a high-fat diet to induce obesity models and randomly divided into a model group,an aerobic exercise group,and a static training group after successful modeling,with 8 rats in each group.During the entire experiment,rats in the normal group were fed a common diet without intervention.Rats in the model group were fed a high-fat diet without intervention.Rats in the aerobic exercise group were given moderate-intensity running exercises.Rats in the static training group were given 6-day/week static training for 8 weeks.The body mass and length of rats were recorded throughout the experiment,and the Lee's index was calculated.After the intervention,the perirenal and peri-epididymal fat weights of rats were measured,and the fat/body mass ratio was calculated.Four items of blood lipids were detected by biochemical methods[triglyceride(TG),total cholesterol(TC),low-density lipoprotein(LDL),and high-density lipoprotein(HDL)];serum nitric oxide(NO),endothelin-1(ET-1),soluble thrombomodulin(sTM),and APN were detected by enzyme-linked immunosorbent assay.The morphological changes of the aorta in each group were observed under the microscope. Results:Compared with the normal group,the body mass,body length,Lee's index,perirenal fat mass,peri-epididymal fat mass,fat/body mass ratio,TG,TC,LDL,ET-1,and sTM in the model group were significantly increased(P<0.05),while the HDL,NO,and APN were significantly reduced(P<0.01).Compared with the model group,the body mass,Lee's index,perirenal fat mass,peri-epididymal mass,fat/body mass ratio,TC,LDL,ET-1,and sTM in the aerobic exercise group and the static training group were significantly reduced(P<0.05 or P<0.01),while the HDL,NO,and APN were significantly increased(P<0.05 or P<0.01).Compared with the aerobic exercise group,NO in the static training group was significantly higher(P<0.05).APN was positively correlated with NO(P<0.01),while APN was negatively correlated with ET-1 or sTM(P<0.01).Aortic morphological observation showed that the degree of endothelial injury in the aerobic exercise group and the static training group was less significant than that in the model group,and the improvement of endothelial cell morphology in the static training group was more notable than that in the aerobic exercise group. Conclusion:Tuina static training and aerobic exercise improved the aortic endothelial injury in obese rats,and the effect of Tuina static training was more significant.The mechanism of action may be related to regulating lipid metabolism and promoting APN secretion.

Objective:To investigate the variations in infrared radiation at Taichong(LR3),Taixi(KI3),and control points before and after menstruation and to examine the infrared radiation patterns associated with Yuan-primordial points of Zang-Fu organs during the physiological menstrual cycle. Methods:Using a point infrared radiation spectrum detection system,we detected the infrared radiation spectra of Taichong(LR3),Taixi(KI3),and the control points located 1 cm away from the two points,in a range of 1.50-18.00 μm wavelengths during the premenstrual,menstrual,and postmenstrual phases in 32 healthy adult women.Subsequently,data mining and analysis were conducted. Results:Before,during,and after menstruation,the infrared spectral shapes of bilateral Taichong(LR3),Taixi(KI3),and their control points were generally consistent,with characteristic infrared spectral wavelengths located at 11.25 μm.Prior to menstruation,the total intensity of infrared radiation at the right Taixi(KI3)was significantly lower than that at the control point(P<0.05),and that at the left Taichong(LR3)was significantly lower than that at the control point(P<0.01).During and after menstruation,the total infrared radiation intensity at both Taixi(KI3)was significantly lower than that of the control point(P<0.05).The wavelength points exhibiting significant differences in the infrared radiation intensity between points and control points were concentrated at the primary peak of 7.50-14.25 μm and the secondary peak of 15.00-17.25 μm. Conclusion:During different menstrual phases,the infrared radiation spectra of Taichong(LR3)and Taixi(KI3)exhibited distinct point specificity,mainly evident in the infrared radiation intensity and wavelength.

Background The serious air pollution of highway toll booths poses a high occupational exposure risk to toll collectors. It is urgent to develop purification methods suitable for airborne particles and microbial pathogens in highway toll booths. Objective To verify the purification effect of low temperature plasma air purifiers on airborne particles and microbes in highway toll booths. Methods Based on controlled-intervention design, we selected three toll booths in an expressway toll station as on-site experimental locations for 6 d (no-intervention period: the low-temperature plasma purifier was turned off in the first three days; intervention period: the purifier was turned on from 9:00 to 17:00 in the following three days). The indoor and outdoor PM_2.5 and PM₁₀ concentrations were continuously monitored during the study. At 9:00, 12:00, and 17:00 of every day during the experiment, indoor and outdoor air samples were collected to analyze the concentration of airborne culturable colonies with a plankton sampler. Airborne particle samples were collected in the outermost exit continuously from 9:00 to 17:00 every day during the experiment using a medium flow particulate sampler, and the species and relative abundance of fungi and bacteria contained in the samples were analyzed by gene sequencing. Independent-sample t test was used to compare the concentration of indoor PM_2.5, PM₁₀, and culturable colonies between the intervention period and the non-intervention period. α diversity analysis, β diversity analysis, and t test were used to compare the diversity and relative abundance of specific species of bacteria and fungi, as well as typical pathogenic bacteria and fungi in the samples between the non-intervention period and the intervention period to reflect the purification effect of low temperature plasma air purifier on airborne PM_2.5, PM₁₀, and microorganisms. Results During the intervention period, the mean indoor concentrations of PM_2.5, PM₁₀, and culturable colonies were lower than those of the no-intervention period (P<0.01 or P<0.001). The ratios of indoor to outdoor concentration (I/O) of PM_2.5 and PM₁₀ during the intervention period were significantly lower than those of the no-intervention period (P<0.001), except the I/O of culturable colonies. Compared with the average concentration at 9:00, the average cleaning rates at 12:00 and 17:00 for PM_2.5 were 49.0% and 46.1%, for PM₁₀ were 49.7% and 45.4%, for airborne culturable colonies were 50.8% and 49.9%, respectively. The β diversity analysis showed that there were significant differences in composition at the level of species of bacteria, and at the levels of genus and species of fungi between the intervention and the no-intervention periods. The relative abundances of 10 species of bacteria such as Lactobacillus and 7 species of fungi such as Torula in the intervention period were significantly lower than those in the non-intervention period, but the relative abundances of fungi such as unclassified_f_cladosporiaceae, trichomerium, and cercospora were higher (P<0.05). For typical pathogenic bacteria, the relative abundances of Lactobacillus and Clostridium_sensu_stricto_1 during the intervention period were 73.5% and 86.9% lower than those in the no-intervention period, and the relative abundance of Talaromyces was 53.5% lower (P<0.05). Conclusion Low temperature plasma air purifier has a good purification effect on indoor PM_2.5, PM₁₀, and culturable colonies in highway toll booths, and likely a limited effect on some fungi.

Bladder cancer is one of the most common malignant tumors in the urinary system. There are a large number of bladder cancer patients globally, concentrated in the middle-aged and old-aged population, and some of them are first diagnosed with muscle invasive bladder cancer or metastatic bladder cancer, with a poor prognosis. In China, bladder cancer has become one of the most important tumors of the urinary system, with its incidence and mortality increasing year by year. The susceptibility of bladder cancer is affected by a combination of environmental and genetic factors, similar to the global trend. Smoking is considered to be one of the most important environmental risk factors for bladder cancer, which is closely related to the pathogenesis of bladder cancer and is one of the major public health problems in China. In terms of genetics, previous studies have shown that polymorphisms in cell cycle regulatory genes, tumor angiogenesis regulatory genes, DNA damage repair genes, and carcinogen metabolism enzyme regulatory genes can significantly affect the risk of bladder cancer in individuals. In recent years, with the development of environmental genomics research, the joint effect of smoking and gene variants on the susceptibility to bladder cancer has also received widespread attention. Exploring the joint effects will help to identify potential susceptibility biomarkers of bladder cancer and provide an important theoretical basis for its prevention and control. In this review, the joint effects of smoking and gene variants on bladder cancer susceptibility were elaborated.
