Tripterygium wilfordii multiglucoside,the primary active constituent of the Chinese materia medica of Tripterygium wilfordii,has anti-inflammatory and immune-regulation properties and is widely used to treat kidney and rheumatic and immunological diseases.However,the potential adverse effects of Tripterygium wilfordii multiglucoside on pediatric gonadal development have limited its clinical application in pediatrics.According to the traditional Chinese medicine theory,the reproductive toxicity of Tripterygium wilfordii is closely associated with deficiency in kidney essence and tian gui disorder.Based on the"kidney essence-tian gui"theory,this study elucidates the transformation of"kidney essence to tian gui"through the qi transformation of"original noumenon to supreme ultimate,"which is synergistically regulated by the accumulation of kidney qi,consolidation of spleen qi,and conveyance and dispersion of liver qi.It is channeled through the interconnected pathways of the thoroughfare channel,conception channel,and governor channel.The physiological process of"kidney essence to tian gui"is damaged by the bitter,cold,and toxicity of Tripterygium wilfordii,leading to kidney asthenia,spleen deficiency,liver depression,and meridian stagnation,causing tian gui dysregulation.Therefore,this study offers traditional Chinese medicine prevention and treatment strategies for pediatric medication safety,including nourishing the kidney essence to replenish the tian gui source,enhancing the middle jiao to strengthen the tian gui guard,regulating liver qi to promote the operation of tian gui,and unblocking the thoroughfare channel,conception channel,and governor channel to ensure the unobstructed pathway of tian gui.

Objective To evaluate the efficacy and safety of enteric-coated metformin hydrochloride capsules(Junlida?)in patients with T2DM and poor glycemic control under lifestyle interventions.Methods In this study,419 patients with T2DM were recruited from 15 research centers from July 2020 to March 2022,and randomly divided into observation(Obs)group(n=209)and control group(Con,n=210)using a multicenter,randomized,double-blind,non-inferiority trial design.Patients in the Obs group were treated with enteric-coated Metformin hydrochloride capsules(Junlida?),and patients in the Con group were treated with Metformin hydrochloride tablets(Glucophage?).The optimal effective dose of 2 g/d was achieved within 4 weeks,and the reasonable dose was maintained until the end of treatment.The treatment period was 24 weeks.HbA1c and its compliance rate,FPG,and body weight were compared between the two groups in full analysis set(FAS)and protocol set(PPS).Safety and adverse events(AE)were evaluated in safety set(SS).Results A total of 414 participants were randomized(207 cases in Obs group and 207 cases in Con group).414 cases in FAS population(207 cases in Obs group and 207 cases in Con group),and 328 cases in PPS population(164 cases in Obs group and 164 cases in Con group),and 414 cases in SS population(207 cases in Obs group and 207 cases in Con group).After treatment,HbA1c,FPG and body weight were lower in both groups(P<0.05)in FAS and PPS.HbA1c compliance rate was not significantly different between the two groups in FAS and PPS(P>0.05).The results of non-inferiority test showed that the lower limit was>-0.4%in both FAS(-0.154,95%CI-0.384～0.069)and PPS(-0.139,95%CI-0.390～0.112),and the Obs group reached non-inferiority end point.The achievement rate,compliance rate,safety index and incidence of AE were not significantly different between the two groups(P>0.05).Conclusions Junlida? demonstrated non-inferiority to Glucophage? in glycemic control and can be safely and effectively used in patients with diabetes.

Objective To explore the current status of penile erection hardness and its influencing factors in patients with non-obstructive azoospermia.Methods From January to December 2024,450 patients with non-obstructive azoospermia were surveyed at the Reproductive Medicine Center of Hospital.A self-made general information questionnaire was used to collect their demographic data.The Erectile Hardness Scale(EHS)was employed to investigate the current status of their penile erection hardness,and a self-made questionnaire was utilized to explore the influencing factors.Results Among the 450 patients with non-obstructive azoospermia,during sexual intercourse,35.3%of the patients reported that their penile erection hardness could reach grade 4(normal state),54.5%reported that it only reached grade 3(sub-optimal state),9.3%reported that it only reached grade 2(slight penile erection),and 0.9%reported that it only reached grade 1(inability to achieve an erection).In the survey of satisfaction with sexual life quality,among the 450 patients,only 24.9%were very satisfied with their sexual life quality;57.3%were basically satisfied;9.6%considered it average;4.0%were dissatisfied;3.1%were very dissatisfied;and 1.1%had no sexual life.alcohol consumption(OR=2.393,95%CI:1.493～3.836),satisfaction with the quality of sexual life(OR=1.455,95%CI:1.118～1.894),educational attainment(OR=0.709,95%CI:0.549～0.917),and the sleep quality in the past month(OR=0.641,95%CI:0.452～0.907).Conclusions Clinical studies have shown that factors such as drinking habits,sexual life satisfaction,sleep quality,and educational attainment collectively influence the penile erection hardness in patients with non-obstructive azoospermia.Therefore,the medical team needs to customize personalized intervention plans and educational materials based on individual differences among patients.Through psychological counseling and lifestyle guidance,they can improve erectile function and the quality of sexual life,promote harmonious marital relationships,and enhance the overall life experience of the patients.

Objective To assess the comparative efficacy of different methods for difficult biliary cannulation in endoscopic retrograde cholangio-pancreatography(ERCP)through a network meta-analysis.Methods Randomized controlled trials(RCTs)that compared the efficacy of different adjunctive methods(early or late needle-knife technique,pancreatic guidewire-assisted technique,pancreatic stent-assisted technique,transpancreatic sphincterotomy,persistent standard cannulation technique)for difficult biliary cannulation with each other were identified.The success rate of biliary cannulation and the incidence of post-ERCP pancreatitis(PEP)were the outcomes of interest.Pairwise and network meta-analysis and ranking according to surface under the cumulative ranking curve(SUCRA)for all methods were performed.Results Eighteen RCTs were identified according to selection criteria,and 2 033 patients were enrolled.The use of transpancreatic sphincterotomy over persistent standard cannulation technique(RR=1.34,95%CI:1.02-1.77)and over pancreatic guidewire-assisted technique(RR=1.26,95%CI:1.00-1.60)significantly increased the success rate of biliary cannulation.Based on SUCRA ranking,transpancreatic sphincterotomy followed by early needle-knife techniques were ranked highest in terms of increasing the success rate of biliary cannulation.Only early needle-knife technique significantly decreased PEP rate when compared with persistent standard cannulation technique(RR=0.53,95%CI:0.30-0.94),whereas both early needle-knife techniques and transpancreatic sphincterotomy led to lower PEP rates as compared with pancreatic guidewire-assisted technique(RR=0.41,95%CI:0.17-0.99;RR=0.49,95%CI:0.25-0.96;respectively).Based on SUCRA ranking,early needle-knife technique followed by transpancreatic sphincterotomy were ranked highest for decreasing the PEP rate of biliary cannulation.Conclusions Transpancreatic sphincterotomy increases the success rate of difficult biliary cannulation in ERCP;early needle-knife technique and transpancreatic sphincterotomy are superior to other interventions in decreasing PEP rates and should be considered as a choice of difficult biliary cannulation.

Objective To observe the effect of the three active ingredients of a Chinese traditional medicine compound named Kang Fu Ling( KFL) against PC12 cells oxidative damage induced by microwave radiation.Methods PC12 cells were differentiated into neuros induced by nerve growth factor ( NGF ) .PC12 cells were incubated for 48 hours after astragalosides,total paeony glycoside and tanshinones were added at different concentrations (1, 3, or 9 μg/ml) .The cells in the control group were cultivated with the only medium of the same volume.Then, cells were irradiated with 30 mW/cm2 microwave for 6 minutes.The morphology of PC12 cells was observed under an inverted microscope soon before and after irradiation and the cell viability was measured by methylthiazolyl tetrazolium ( MTT) colorimetry.Reactive oxygen species ( ROS ) was determined using active oxygen probe 2′, 7′-dichlorodihyarofluolescen diacetde ( DCFH-DA ) while malonyldialdehyde(MDA) was measured in the homogenate of PC12 cells through thiobarbituric acid ( TBA) reactive substance assay.Results The cell morphology of each group showed no obvious difference.6 h after irradiation, the viability of irradiation control group measured by MTT declined apparently(P<0.01)compared with the normal control group.The 3 μg/ml astragalosides treatment group increased the viability of PC12 cells after microwave exposure ( P <0.01).The contents of ROS and MDA were increased after irradiation(P<0.01).However, in the three active ingredients of Kang Fu Ling treatment groups, both ROS and MDA were much lower than in irradiation control group.Conclusion Astragalosides, total paeony glycoside and tanshinones, which are the three active ingredients of Kang Fu Ling, all have protective effect against PC12 cell injury caused by microwave radiation,possibly by scavenging free radicals and reducing oxidative stress injury.
