OBJECTIVE: To study the links between chronic pyelonephritis (CPN) and immune function, and the action mechanism of Yishenkang granule on CPN. METHODS: A total of 120 CPN cases were randomly assigned to Yishenkang granule group, Sanjing tablet group and western medicine group, which were compared with healthy control group. The levels of the peripheral blood T lymphocyte subsets, serum immunoglobulin, complement, secretory IgA in urine and the cell factor IL-2 in CPN cases before and after treatment were detected by monoclonal antibody method, agar diffusion method, radioimmunoassay, radioimmune balancing method and compared with those in healthy control group. RESULTS: In CPN cases compared with healthy control group, the levels of serum immunoglobulin, complement, secretory IgA in urine were significantly lower while the level of cell factor IL-2 were significnatly higher (P

Objective To explore the relationships between loneliness and sleep quality of undergraduates.Methods 751 undergraduates were investigated by UCLA Loneliness Scale and Pittsburgh Sleep Quality Index( PSQI).Results (1) No gender,grade and origin differences on loneliness were found,but non-only child undergraduates(43.09±7.22)felt lonely more than only-child undergraduates(41.37±8.38)(t=2.95,P=0.003).(2) No gender,grade and yes or no only child differences on the total score of PSQI were found,but undergraduates come from country (5.00±2.68)scored higher than those from city(4.59±2.79)(t＝2.019,P＜0.05).(3)Loneliness had significant positive correlations with the total score on the PSQI and the six components(except sleep duration)(r=0.12～0.27,P＜0.05～0.01).Lonely(5.72±3.25,1.20±0.93,1.09±0.70,0.23±0.64,1.64±0.93)and non-lonely undergraduates (4.63±2.56,0.99±0.79,0.96±0.53,0.08±0.37,1.39±0.85)differ significantly in total score of PSQI,sleep latency,sleep disturbance,sleep medication and daytime dysfunction(t=2.096～3.681,P＜0.05～0.001).Conclusion Loneliness of undergraduates maybe influence their sleep quality.

B-ultrasonic manifestations of 65 cases of cryptorchlchsms including location and size as well as internal structure of tests are analysed.Among these seventy-four per cent cases Were con-firmed by operations.It is Considered that B-ultrasonic imaging has important diagnostic value for cryptorchidism.

Objective To evaluate the therapeutic effect of ureteroscopy with holmium laser on ureteral stricture associated with calculi.Methods The clinical data of 36 cases of ureteral stricture associated with calculi undergoing ureteroscopy with holmium laser treatment were analyzed retrospectively with 26 cases of male patients and 10 cases of female patients.The age was 26-65 years.There were upper and middle ureteral stricture associated with calculi in 8 cases,and lower segment of ureteral stricture associated with calculi in 28 cases.All the patients were treated with ureteroscopy with holmium laser.All cases were followed up for 6-12 months.In the follow-up of 36 cases B ultrasound and urinary tract flat piece or intravenous urinary tract imaging were performed to evaluate the therapeutic effect.Results Thirty-six patients underwent ureteroscopy with holmium laser successfully.No conversion to open surgery occurred.Mean operating time was 30 (20-45) min.Mean hospital stay postoperatively was 3-5 d.Postoperative 8 cases with low thermal,alleviated by the anti-infection treatment,no ureteral avulsion,leakage and severe complications such as hemorrhage.Postoperative follow-up,32 cases (89％,32/36) were cured and 4 cases (11％,4/36) were improved.Conclusion Ureteroscopy with holmium laser in treatment of ureteral stricture associated with calculi is a simple and effective minimally invasive method.

Objective To establish a test method of dichloromethane,1,1-dichloroethylene,1,2-dichloroethylene,1,2-dichloroethane in drinking water with headspace gas chromatography.Methods Halogenated alkane hydrocarbon in the water was extracted by headspace technique,then analyzed with DB-624 capillary column.In the same time,determined with GC by controlling the temperature.Retention time of the peaks was used for qualitative analysis,while external standard method was used for quantitative analysis.Results The linear ranges for dichloromethane,1,1-dichloroethylene,1,2-dichloroethylene,trans-1,2-dichloroethylene,1,2-dichloroethane were 0.85-168,0.07-12.1,0.40-77.8,0.53-119 and 1.2-265 ?g/L respectively,the determination limits were 0.83,0.07,0.40,0.53 and 1.10?g/L respectively,r≥0.999 5,the rate of recovery were 102.5%-113.8%,and RSDs were 5.5%-11.8%.Conclusion This method is simple,rapid and sensitive,can efficiently separate and accurately determine 5 kinds of halogenated alkane hydrocarbon in the water and only takes 5.2 minutes.

Objective To discuss the effect of preventing postoperative incision fat necrosis by the method of evacuated suture of reducing tension. Methods The method of evacuated suture of reducing tension was used in 158 cases. Age of them was 22～83 years old,mean 52 years old. There were thick fat tissues in the sub-skin of all patients.The fat average thickness was from 4 0～8 0cm.Results The treatment group had 158 cases, of which, lumbar incision had 62 cases, subcostal incision had 5 cases and hypogastric median incision had 91 cases. Among 158 cases,there were 4 cases of incision fat necrosis, 3 cases of incision infection and the others were one-stage healing.The control group had 97 cases. Among them, there were 18 cases of fat necrosis, 4 cases of incision infection and the others are one-stage healing. Conclusions Method of evacuated suture of reducing tension to prevent incision fat necrosis has satisfactory efficacy and worth of clinical popularization and application.

Objective To treat urinary calculi with pneumatic lithotripsy under non-endoscopy.Methodes We applied the pneumatic lithotripsy machine,which made in China,to treat huge or staghom nephrolith and calculi of anterior urethra under non-endoscopy,taken out stone fragmentations after lithotripsy.There was 1 case of huge nephrolith,7cases of staghom nephrolith,3 cases of anterior urethral calculi.Results Every case of nephrolith was successfully performed by using lithotrisy and extracted stones only one case.1 case in total nephrolith cases was found residual stones and sick-side renal functions were improved than before in all casws followed up for 3 moths to 2 years.the cases of anterior urethral calculi urinated fluently and had no urethral stenoses followed up 1～2 years.Conclusion This kind of operation used pneumatic lithotripsy to treat urinary calculi under non-endoscopy is safe,slight injury and curative effect is reliable.

Objective To evaluate the clinical value of laparoscopy in adrenal surgery.Methods From December 2000 to May 2006,86 cases of adrenal space-occupying lesion received laparoscopic adrenalectomy via transperitoneal(n=1),retroperitoneal(n=81) and hand-assisted transperitoneal(n=4) approach,respectively.Results All the operations were successful without conversion to open surgery and severe complications.The mean operative time was 72 min(range,50-175 min).The mean blood loss was 54 ml(range,15-120 ml).The postoperative hospital stay was 6.3 d(range,5-8 d).Imaging examinations revealed no tumor recurrence and metastasis during the mean follow-up period of 26.5 months(range,2-65 months)in 86 patients.The symptoms of patients with functional tumor was alleviated or disappeared.Conclusions Laparoscopic adrenalectomy has advantages of minimal invasion,less blood loss,and quicker recovery,and it should be the fist choice for most adrenal space-occupying lesions.
