Objective: To explore the efficacy and surgical techniques of ultrasound-assisted transurethral flexible ureteroscopic holmium laser incision and internal drainage in the treatment of special renal cystic diseases，so as to provide reference for the diagnosis and treatment of such diseases. Methods: The clinical data of 48 patients with special renal cystic diseases treated during Jan.2019 and May 2023 were retrospectively analyzed.The diagnosis was made by computed tomography urography (CTU) and three dimensional urinary tract reconstruction before operation.All patients received the abovementioned surgery in semisupine lithotomy position.The general information，clinical data，and incidence of complications were analyzed. Results: There were 27 males and 21 females，with an average age of (48.0±7.5) years，including 22 cases of parapelvic cysts，6 cases of endogenic simple renal cysts with an average diameter of (5.0±1.0) cm，and 20 cases of renal calyceal diverticulum with stones，with an average diameter of (2.5±1.3) cm for the diverticulum and an average diameter of (1.5±1.0) cm for the stones，which were located in the upper or middle calyces.In 7 cases，ureteroscopic localization was difficult，and the surgery was completed with percutaneous renal puncture needle assisted localization.Ureteral stenosis was detected in 2 cases during surgery，and surgery was performed 4 weeks after double J tubes were placed.The remaining operations were successfully completed.The average operation time was (42.0±14.5) minutes，and average hospital stay was (2.0±0.5) days.During the follow-up of (12.0±8.5) months，lumbar pain improved in 27 cases (100%)，renal cysts disappeared in 23 cases (82.1%,23/28)，cysts significantly reduced by ≥50% in 4 cases (14.3%,4/28)，slightly reduced by <50% in 1 case (3.6%,1/28)，and the renal calyx diverticulum disappeared in 20 cases (100%).Gross hematuria and lower back pain occurred in 2 cases，and no other complications developed. Conclusion: Ultrasound-guided transurethral flexible ureteroscopic holmium laser incision and internal drainage is a safe and effective treatment for special benign renal cystic diseases.When ultrasound-guided flexible ureteroscope localization is difficult to perform，percutaneous renal puncture needle may be applied.

Objective:To analyze the research and development of control system for airbag pressure of intelligent tracheal catheter,and its application effect in clinical practice.Methods:The hospital designed an intelligent self-adaptive control system for cuff pressure of tracheal catheter,which can rationally apply main components such as single chip microcomputer,display screen,control panel,pressure monitoring module,inflation device and solenoid valve,etc..This control system connected the measuring module of pressure through single chip microcomputer,so as to continuously detect the airbag pressure of tracheal catheter.An inflation and deflation algorithm was independently researched and developed to control air pump or solenoid valve to inject or release part of the gas to the airbag,so as to achieve intelligent control for the pressure of airbag.Sixty patients underwent endotracheal intubation who admitted to the department of general surgery of Wuhan Hospital of Traditional Chinese Medicine from January 2022 to January 2023 were selected as the study objects,and they were divided into control group(n=30)and observation group(n=30)according to random number table method.The cuff pressure of endotracheal intubation of patients in control group were managed by conventional method.The intelligent adaptive control system was adopted to manage the cuff pressure of endotracheal intubation for patients in the observation group.The complications,compliance rate of airbag pressure,the instantaneous maximum value of airbag pressure during sputum aspiration,insertion of gastric tube,and turning over of body were compared between the two groups after intubation.Results:The incidence of complication included cough,trachyphonia,dysphagia and bloody sputum after tracheal intubation in the observation group were 6.66%,which was significantly lower than 33.33%in the control group,and the difference was statistically significant(x2=6.667,P<0.05).The compliance rate of the pressure(25-30cmH2O)of airbag in the control group was 92.83%,which was significantly lower than 97.78%in the observation group,and the difference was statistically significant(x2=14.698,P<0.05).The instantaneous maximum values of airbag pressure during sputum aspiration,insertion of gastric tube and turning over were(28.24±3.65)cmH2O,(27.98±4.25)cmH2O and(28.65±4.87)cmH2O in observation group,respectively,which were significantly lower than those in control group,and the differences were significant(t=17.930,19.208,16.485,P<0.05).Conclusion:The application of intelligent adaptive control system for cuff pressure of tracheal catheter can maintain the airbag pressure of tracheal catheter at normal level(20-30 cmH2O),and reduce complications,and improve the compliance rate of airbag pressure.

AIM:To investigate the effect of gastrodin(GAS)on microglia-mediated inflammatory response after hypoxic-ischemic brain damage(HIBD)neonatal mice by regulating the expression of JAK1/STAT1 pathway through C-C chemokine recepeor 5(CCR5).METHODS:Forty-eight C57BL/6J mice at about 10 days after birth were randomly divided into sham group,HIBD model group and HIBD+GAS group.BV-2 microglia were divided into control(Con)group,oxygen glucose deprivation(OGD)group,oxygen glucose deprivation with gastrodin intervention(OGD+GAS)group,GAS group,Maraviroc(MVC)group,OGD+MVC group,and OGD+MVC+GAS group.The mRNA expression of CCL4 and CCR5 were detected by RT-qPCR.The protein expression of CCR5,p-JAK1,p-STAT1,tumor necrosis factor-α(TNF-α)and interleukin-1β(IL-1β)were detected by Western blot.The expression of CCR5,p-JAK1 and p-STAT1 in cells were observed by immunofluorescence staining.RESULTS:(1)Compared with sham group,the expression levels of CCL4 and CCR5 mRNA,and CCR5,p-JAK1 and p-STAT1 proteins were significantly higher in the ischemic side of the corpus callosum in HIBD group(P＜0.05).(2)Compared with Con group,the protein levels of CCR5,p-JAK1 and p-STAT1 significantly increased in BV-2 cells of OGD group(P＜0.05).The protein levels of CCR5,p-JAK1 and p-STAT1 in BV-2 cells of OGD+GAS group were significantly lower than those of OGD group(P＜0.05).(3)Maraviroc did not cause significant BV-2 cell death in the 0～80 μmol/L range.The p-JAK1 and p-STAT1 protein levels in MVC+OGD group were significantly lowered compared with OGD group(P＜0.05),but no significant difference was found between MVC+ OGD and OGD+MVC+GAS groups.CONCLUSION:Gastrodin can exert neuroprotective effects via CCR5/JAK1/STAT1 signaling pathway.

Objective To analyze the situation of life sciences and medical research involving human subjects conducted in a public hospital in Ningxia from 2020 to 2022 and explore the problems in the current management of such research and pro-vides suggestions for improvement.Methods Data were collected from research project application documents,task assign-ments,progress reports,final reports,and statistical tables of clinical drug trials conducted in the hospital from 2021 to 2022.Statistical analysis was performed on the life sciences and medical research involving human subjects.Results The number of research projects involving human subjects in the hospital increased annually from 2020 to 2022,accounting for more than 50%of the total projects.Over the three years,the sample size exceeded 100,000,and the number of projects with a cumulative collec-tion of more than 3,000 individuals showed an upward trend.However,the project registration rate was less than 10%.These types of research involve a large number of biological samples and information data,which have research value.However,re-searchers lack awareness of project registration,highlighting the need for greater attention from the hospital.Conclusion It is a trend to explore the medical value of this type of research in depth.The hospital should closely follow relevant national and re-gional policies,conduct dynamic monitoring and evaluation,and enhance supervision and management capabilities as a key factor in protecting biological samples and information data.This study also provides reference for other public hospitals in carrying out related regulatory work.

Objective:To investigate the current situation and characteristics of post-intensive care syndrome in elderly patients during the transitional period, and explore its influencing factors.Methods:From December 2022 to September 2023, convenience sampling was used to select 119 elderly patients in the Intensive Care Unit of China-Japan Friendship Hospital as the research subject. The General Information Questionnaire, Short Physical Performance Battery, Fatigue Scale-14, Barthel Index, Hospital Anxiety and Depression Scale, and Mini-mental State Examination were used to evaluate patients for post-intensive care syndrome from cognitive, psychological, and physiological aspects 7 days after their transfer from the Intensive Care Unit. Binomial Logistic regression was used to analyze the influencing factors of post-intensive care syndrome in elderly patients.Results:Among 119 elderly patients, 84 developed post-intensive care syndrome, with an incidence of 70.6%. The binomial Logistic regression showed that women and high nutritional risk were risk factors for the occurrence of post-intensive care syndrome in elderly patients ( P<0.05) . Conclusions:The incidence of post-intensive care syndrome is high in elderly patients during the transition period, with females and patients with high nutritional risk being prone to developing post-intensive care syndrome. Medical and nursing staff should pay attention to identifying gender differences, focus on high-risk populations, and dynamically evaluate different symptoms early on to provide precise interventions for elderly patients.
