Objective To study the feasibility of laparoscopic cholecystectomy accompanied by simultaneous umbilical hernia repair.Methods Twenty-four adult patients received laparoscopic cholecystectomy accompanied by simultaneous umbilical hernia repair in our hospital from November 2003 to April 2008.An incision was made in navel defect and entered the abdominal cavity under a direct vision.LC was performed by 3-trocar technique.Umbilical hernia was repaired by Mayo' style.Results The operation was successfully completed in all the cases.The operation time ranged from 35 to 65 minutes (mean,48 minutes),the blood loss was 5-30 ml(mean,16 ml),and hospital stay after the operation was 3 -4 days.No patient dereloped wound infection or skin necrosis.No recurreme was found during a 1-to 54-month follow-up(mean,28.6 months).Conclusions Laparoscopie cholecystectomy accompanied by simultaneous umbilical hernia repair is a safe and effective procedure.Mayo repair is simple and effective for umbilical hernia with less fascial defects.

To study the changes in every part of the beta-adrenergic signal transduction pathway and their effects on ischemic preconditioning of rat myocardium in vivo. SD rats were divided into three groups: IP group, I/R group and CON group. The IP group was further divided into PC1-, 2-, 3-, and PC1+, 2+, 3+ groups according to preconditioning procedure. The rats received surgical procedure and underwent left coronary artery occlusion and reperfusion. We analyzed the infarct size by TTC staining, measured serum myocardial enzymes, studied the beta-AR Bmax and Kd by radioligand binding assay of receptors, checked the activity of AC and PKA by the method of biochemistry and examined the content of cAMP by radioimmunoassay. The infarct area was much smaller in the IP group than in the I/R group (P < 0.001), while the enzymes were significantly higher in I/R (P < 0.001). The Bmax of beta-AR in IP was much higher than that in I/R (P < 0. 001), but no difference in Kd could be seen between IP and I/R groups. In IP, the activity of AC and PKA and the content of cAMP were higher than those in I/R (P < 0.05, 0.002 and 0.001, respectively). In the procedure of preconditioning, the content of cAMP and the activity of PKA showed the characteristic of cyclic fluctuation. Ischemic preconditioning can protect the heart from necrosis and reduce endo-enzyme leakage. The system of beta-adrenergic signal transduction pathway probably takes part in the protection effect of the IP, which might be elicited by the PKA.

Objective To investigate the feasibility and safety of laparoscopic cholecystectomy(LC) in patients with chronic renal dysfunction at azotaemic stage.Methods Clinical data of 7 patients accompanying chronic renal dysfunction at azotaemic stage treated with LC between May 2004 and September 2006 were analyzed retrospectively.The operation was performed under general anesthesia and endotracheal intubation.The CO2 pressure was maintained at 9～12 mm Hg.The LC was conducted with 3-port technique in 5 patients and 4-port technique in 2.Results The LC was completed smoothly in all the 7 patients.Patients' renal dysfunction was not aggravated.There was no significant difference between pre-and post-operative time in levels of blood urea nitrogen(11.92?4.06 mmol/L vs 12.16?3.76 mmol/L;t=0.50,P=0.633) and blood creatinine(208.62?134.37 ?mol/L vs 204.20?125.53 ?mol/L;t= 0.51,P=0.626).As compared with preoperative levels,the creatinine clearance rates were not significantly changed at 2 weeks after operation in 3 patients(40.03 ml/min vs 45.61 ml/min;32.28 ml/min vs 38.93 ml/min;56.72 ml/min vs 51.60 ml/min).Follow-up checkups for 4～20 months(mean,10 months) showed no aggravation of renal dysfunction.Conclusions Laparoscopic cholecystectomy is a feasible and safe procedure for patients with chronic renal dysfunction at azotaemic stage.

Objective To explore the correlation of single nucleotide polymorphism ( SNP ) in Nrf2 gene with acute mountain sickness ( AMS) among Han populations in China .Methods As a nested case-control study , 603 Chinese Han young men who had been quickly exposed to 3700 m were adopted and divided into case group and control group ( 369 vs 234,respectively) by Lake Louise Self-assessment Scoring System(LLSS).The Sequenom Mass Array system was used to detect the SNPs of rs10497511 and rs2364722 in Nrf2 gene.Results Alleles of rs10497511 and rs2364722 were respec-tively detected in both case and control groups , which were T-C and A-G.Statistically significant difference was not found in allele frequencies ( P>0.05 ) .Further analysis showed that there was still no significant difference between the codomi -nant, dominant and recessive genotype models (P>0.05).Conclusion rs10497511 and rs2364722 of Nrf2 gene may not be related to susceptibility to AMS in Chinese Han populations .

OBJECTIVETo investigate the effect and safety of extracorporeal shock wave (ESW) in the treatment of pain symptom of type III B prostatitis.

METHODSWe treated 50 cases of type III B prostatitis by ESW once a week for 4 weeks. Then we evaluated the clinical effect and safety of the therapy based on the NIH-CPSI scores, visual analogue scale (VAS) scores, IIEF-5 scores, prostate volume and morphous, state of urination, color of urine, results of routine semen analysis, and changes of cytokines (IL-6, TNF-α and IL-1β) in expressed prostatic secretion (EPS).

RESULTSAll the patients successfully accomplished the treatment. Compared with the baseline, decreases were observed after 4 weeks of cytokine treatment in the pain scores (14. 61 ± 1. 82 vs 9. 36 ± 1. 47, P <0. 01), urination symptom scores (4. 59 ± 1. 01 vs.4. 66 ± 0. 89, P >0. 05) , quality of life scores (6. 51 ± 1. 03 vs 4. 56 ± 1. 02, P <0. 01), NIH-CPSI (25. 43 ± 1. 72 vs 18. 28 ± 2. 32, P <0. 01 ), and VAS (6. 59 ± 1. 10 vs 3. 02 ± 1. 07, P < 0. 01). The concentration of IL-6 in the EPS was significantly increased ([55.82 ± 6. 28] vs [86.59 ± 4. 55] ng/ml, P <0. 01) , while the level of TNF-α ([3.89 ± 0. 12] vs [3. 19 ± 0.22] ng/ml, P<0.01) and that of IL-1β ([3.21 ± 1.01] vs [1.48 ± 0.95] ng/ml, P< 0. 01) remarkably reduced after treatment. However, there were no statistically significant differences in IIEF-5 scores (18. 58 ± 2. 03 vs 18. 51 1. 89, P >0. 05) or various sperm parameters before and after treatment (P >0. 05). And no significant changes were observed in the prostate volume, morphous or internal echoes.

CONCLUSIONThe ESW therapy is effective and safe for the pain symptom of type III B prostatitis.
