Objective To find a safe and effective management for upper ureteral calculi after failure of extracorporeal shock wave lithotripsy(ESWL).Methods Under a F20.8 endoscope(EMS Ⅲ,Switzerland),percutaneous nephrolithotripsy was performed with pneumatic and ultrasonic power on 43 patients with upper ureteral calculi after having been treated by ESWL for 1 or 2 times.Results The procedure was completed in 42 of the patients with a mean operation time of 60 min(35 to 75 min),mean time for calculi removal of 12 min(5 to 20 min),and mean blood loss of 50 ml(20 to 150 ml).One patient was converted to open surgery because of failure of percutaneous renal puncture.One patient developed haematoma after the procedure and then was cured by conservative therapy without receiving blood transfusion.One patient had fever due to infection and was cured after antibiotic therapy.42 patients were followed up for 2 to 18 months(mean,6.4 months);none of them had massive hemorrhage,infection,hydronephrosis,or recurrence of the calculi during the period.Conclusions Percutaneous nephrolithotripsy with pneumatic and ultrasonic power is safe,minimally invasive,and effective for upper ureteral calculi after failure of ESWL.

Objective To summarize our experience in prevention and treatment of stricture after esopageal burns in the past thirty years.Methods There were 168 cases in this series.Of them,158 cases underwent surgical management in this study.Modified intraluminal stenting was used in 34 cases, colon interposition without resection of strictured esophagus in 77 cases,gastric transposion with resection of the stricture in 27,repair of cervical stricture with platysma myocutaneous flap in 22,and miscellane- ous operation in 12.Eleven cases experienced operation twice or more at our department.Results Twenty-nine cases recovered after treatment with intraluminal stenting,and 5 re-experienced stricture after stent removal.One of the 5 cases with failed stent responded to bougienage,and the remaining 4 cases re- quired esophageal reconstruction later.Of the 77 colon interpositions,5 cases died postoperatively,and complications of cervical anastomotic fistula occurred in 14 cases,anastomotic stenosis in 4,and abdomi- nal incision dehiscence in 2 cases.In the 27 cases with gastric transpositions,postoperative complications of anastomotic stricture occurred in 2 cases and empyema in 1 patient.There was a cervical leak in 3 ca- ses of the 22 cases treated with the repair of cervical esopageal or anastomotic stricture with a platysma myocutaneous flap.In the 12 cases treated with miscellaneous operation,one died of intestinal obstruc- tion.All the survivors had regular diet after discharge.Conclusions Intraluminal stenting can prevent the formation of caustic esophageal stricture.The location of the cicatricial esophagus dictates whether to perform concomitant esophagectomy during esophageal reconstruction.Platysma myocutaneous flap repair is an excellent method for the treatment of severe cervical esophageal or anastomotic stricture.

Objective To evaluate the clinical outcome and relative factors of intervention treatment for atherosclerotic renal artery stenosis in elderly patients.Methods The clinical data of 79 patients diagnosed as atherosclerotic renal artery stenosis by angiography and treated by revascularization were analyzed.Results There were 55(69.6%)successes and 24(30.4%)failures in decreasing blood pressure and 28(35.4%)successes and 51(64.6%)failures in improving renal function after intervention treatment.Predictors of favorable outcome of intervention treatment in decreasing blood pressure were related to lower urine protein,higher glomerular filtration rate,higher systolic and diastolic blood pressure before treatment,lower resistance index(RI)of renal artery,and no complication of cerebral vascular diseases.Predictors of favorable outcome of intervention treatment in improving renal function were related with percentage of angiographic stenosis,category of antihypertension and lower urine protein.The logistic regression analysis showed that the percentage of angiographic stenosis was the most important predictor of intervention treatment for blood pressure control,age and level of serum creatinine before intervention treatment were the most important predictors of intervention treatment for improving renal faction.Conclusion Percentage of stenosis(≥85%),age(133 ?mol/L)can be used as the predictors of therapeutic success for renovascular stenosis in older patients.

OBJECTIVETo discuss the anti-tumor effect of Xihuang pill on tumor-bearing rats and its effect on the immune clearance function of tumor-bearing organisms.

METHODWalker256 tumor cells were adopted to establish the tumor-bearing rat model. The rats were randomly divided into five groups: the normal control group, the model control group, the lentinan group and Xihuang pill low dose, middle dose and high dose groups, with 10 rats in each group, and continuously treated and given drugs for 14 d after modeling. Blood and tumors were collected from abdominal aorta to calculate the tumor inhibition rate. The content of CD3+, CD4+, CD8+ T cells and adhesion molecule B7-1 (CD80) in peripheral blood were detected by flow cytometry (FCM). The expressions of IL-2 and IFN-gamma in were determined by ELISA.

RESULTThe tumor inhibition rate of the Xihuang pill high dose group was 33. 1 percent. Compared with the model group, the Xihuang pill large dose group showed significantly low IL-2, IFN-gamma, CD3+, CD4+, B7-1 in peripheral blood, with statistical significance in their differences (P < 0.05).

CONCLUSIONXihuang pill could show its anti-tumor effect by enhancing the immune clearance function and increasing IL-2, IFN-gamma, CD3+ T, CD4+ T, B7-1 in peripheral blood.

OBJECTIVE: To establish a 15-plex rapid STR multiplex amplification system. METHODS: Fourteen auto-chromosome loci and one sex-chromosome were selected to compare the situations of allelic losses and nonspecific amplication under different conditions. FastStart Taq DNA polymerase and DNA standard sample 9947A were used during amplification and optimization process.15-plex rapid STR amplification system was achieved by performing various experiments including selection of amplification conditions and the volume of DNA polymerase, adjustment of inter-locus balance, optimization of rapid amplification, screening of reaction buffers, selection of reaction volume, and a variety of additives. RESULTS: Using 10 μL rapid PCR system, including 1 ng DNA templates, 0.4 μL polymerase and 10xFastStart high fidelity reaction buffer, a complete and well-balance DNA profile of 15 STR loci for standard genomic DNA was obtained in 32 minutes, without the allele drop-out and non-specific amplicons. Meanwhile, 5% glycerinum, 0.01% gelatin, 0.05% gelatin and 5 mmol/L ammonium sulfate could be used as the reactive additive during the amplification procedure. CONCLUSION The 15-plex rapid STR multiplex amplification system can be used to decrease reaction time and enhance sample throughput.

Objective To investigate clinical manifestation of unspecified functional bowel disorder (UFBD), the features of coexistence with functional gastrointestinal disorder (FGID) and its relationship with psychological factors and sleep disturbance in the Chinese Army servicemen.Methodsc FGIDs were diagnosed based on the RomeⅢ Modular Questionnaire. The subjects were 189 servicemen with UFBD (UFBD group) and 372 without FGID (control group). All subjects completed symptom checklist 90 (SCL-90) and Pittsburgh Sleep Quality Index (PSQI) questionnaire.Results'Have to rush to the toilet when having a desire to defecate' was the most frequent symptom of UFBD (93.7%). More than one half of UFBD patients had the symptom 'a feeling of incomplete emptying as bowel movements' or 'straining during bowel movements'. Twenty-eight percent of UFBD subjects had combined FGID (namely cFGID). Among them, the most frequent was proctalgia fugax (7.9%), followed by cyclic vomiting syndrome (6.3%), functional fecal incontinence (6.3%), functional dyspepsia (4.8%) and belching (4.8%). The UFBD group scored significantly higher than the control group in the global severity index (GSI) and in all SCL-90 subscales (P<0.05). The scores of the four domains (sleep quality, sleep latency , sleep disturbance and daytime function disorder), total PSQI score and proportion of poor sleeping quality were significantly higher in the UFBD group than in the control group (P<0.05). The subjects scored significantly higher in combined FGID group than in UFBD group in GSI and in all of SCL-90 subscales, except for phobic anxiety subscales (P<0.05). However, there was no significant difference in each domain, total PSQI and proportion of poor sleeping quality between the cFGID group and UFBD group (P>0.05).ConclusionPathogenesis of UFBD may be closely correlated with psychiatric and psychological factors and sleep disturbance. cFGID are associated with an increased severity of psychopathological features.
