Objective To evaluate the efficacy of percutaneous laser hypothermia in the treatment of lumbar discogenic pain. Methods From June 2006 to March 2008,35 patients with lumbar discogenic pain were treated by low-frequency laser hypothermia in our hospital with 1 second impulse time,1 second interval time,3.5 w power,and 30 minutes duration. The effectiveness of the therapy was evaluated afterwards. Results Among the cases,15 patients were treated by one operation,20 patients received a second therapy,and 6 underwent the therapy for totally 3 time; the treatment was effective in 32 cases (excellent in 7,good in 24,and fair in 1). The therapy is ineffective in 2 cases. One case was converted to open surgery for unsatisfying outcomes of the laser hypothermia. The total effective rate was 91.4%(32/35),and fineness rate was 88.6%(31/35). Conclusions Percutaneous laser hypothermia is an effective treatment for lumbar discogenic pain. The indications for the procedure should be selected strictly.

Objective To investigate the relationship between diabetic retinopathy(DR) and the state of diabetes mellitus(DM) control.Methods The factors for the occurrence and development of DR were analyzed by non conditional Logistic regression model.Results 5 significant factors were screened out,which were urinary microalbumin excretion index(ALB/Cr),blood glucose before breakfast,glycosylated hemoglobin(HbAlc),diabetic neuropathy and course of DM.And the sugestible threshold value of blood glucose before breakfast is 7.90mmol/L at which we can prevent the occurrence of DR,and at 7.15mmol/L,occurrence of DR can be strictly controlled.Conclusion The state of controlling blood glucose and other complications in DM patients influences the occurrence and development of DR.

Objective To investigate the changes of Na~+,K~+-ATPase activity in the proximal tubules (PT) of type 2 diabetes mellitus(T2DM) and the correlation of PT Na~+,K~+-ATPase activity and endogenous digitalis-like substance (EDLS). Methods Female Wistar rats were developed a rat model of T2DM and then divided into 3 groups after injected stretozotocin, that is, 5 weeks group, 7 weeks group and 9 weeks group. The PT were microdissection by freehand. Na~+,K~+ -ATPase activity of PT were determined by liquid scintillation counter. Serum EDLS and insulin were determined using radioimmunoassay. Results Compared with control group, T2DM rats were associated with hyperglycemia, hypertriglyceridemia, dyslipidemia, and insulin resistance; Na~+,K~+-ATPase activity of PT in T2DM rats was significantly increased, and there was no significant difference among 3 sub-groups. Serum EDLS level was significantly enhanced in T2DM, however, EDLS levels were no significant difference among 3 sub-groups. Na~+,K~+-ATPase activity of PT had negative relation with EDLS level in serum. Conclusion Na~+,K~+-ATPase activity of PT in T2DM rats is increased and EDLS level in serum decrease may play a important role.

The correlated proteome of Penicillium marneffei resistant to fluconazole was investigated in the present study, in which 11 strains of P. marneffei of both the mycelial and yeast forms sensitive to fluconazole were cultivated in Sabouraud's liquid medium containing 8 g fluconazole and the MICs of fluoconazile to P.marneffei before and after inducing cultures were tested by E-test method. The strains of the mycelial and yeast forms showing the most significant increase in MIC value were selected and the protein clip CM10 was used to detect the proteome differences before and after inducing cultures. It was found that 11 strains of the mycelial forms and 2 strains of the yeast forms could tolerate the action of fluconazole and could grow at a drug concentration of 8 μg/mL. Furthermore, the MICs of fluoconazole to the mycelial forms were significantly increased after 7 days of inducing culture and the geometric means of MICs were increased from 1.22 μg /mL to 55.56 μg/mL. After the mycelial forms had been induced to be resistant, 16 proteins were highly expressed with specific expression of the 4581.1 Da and 6109.7 Da proteins; whereas 22 resistant yeast form were highly expressed with specific expression of the 3575.2 Da, 8507.0 Da and 8563.3 Da proteins. These results suggest that the mycelial form of P.narneffei seems to be more tolerant to the action of fluconazole than the yeast form. The resistance of these organisms to fluconazole may be associated to some specific proteins.

Objective To study the results of laparoscopic approach in the treatment ot gallbladder and common bile duct stones.Method The authors reviewed data of 60 patients with gallbladder and bile duct stones treated laparoscopically.Results All the 60 patients treated with laparoscopic cholecystectomy and laparoscopic transcystic common bile duct exploration (LcTDE) were successful.There were 1 bile duct stone in 32 patients,and 2 to 6 bile duct stones in 28 patients.The operation time was (38.7±15.1) min and the hospitalization time was (5.5±2.1) days.One patient developed biliary fistula postoperatively which healed after 7 days of conservative treatment.One patient had bile duct residual stone which was treated by ERCP.The remaining patients were well.Conclusion Laparoscopic transcystic common bile duct exploration using a mini incision and primary suturing of the bile duct was simple,safe and efficacious.

[ ABSTRACT] AIM:To investigate the potential role of exogenous hydrogen sulfide ( H2 S) and ATP-sensitive po-tassium ( KATP ) channels in chronic stress-induced colonic hypermotility.METHODS:Male Wistar rats were divided into water avoidance stress ( WAS) group and sham WAS ( SWAS) group.Organ bath recordings were used to test the contrac-tile activity of colonic strips.The effects of H2 S donor NaHS and pretreatment with glibenclamide on the contractions of co-lonic smooth muscle were studied and the IC50 of NaHS was calculated.The localization and expression of the subunits of KATP channels were determined by the methods of immunohistochemistry and Western blotting.RESULTS:WAS increased contractile activity of colonic strips.NaHS concentration-dependently inhibited the spontaneous contractions of strips from the SWAS and WAS rats.The IC50 of NaHS for longitudinal muscle ( LM) and circular muscle ( CM) of the WAS rats was 0.2033 mmol/L and 0.1438 mmol/L, significantly lower than those of the SWAS rats.Glibenclamide significantly in-creased the IC50 of NaHS for LM and CM from the SWAS and WAS rats.In both SWAS and WAS rat colon, Kir6.1, Kir6.2 and SUR2B were expressed on the plasma membrane of the smooth muscle cells.WAS treatment resulted in up-reg-ulation of the expression of Kir6.1 and SUR2B in the colon devoid of mucosa and submucosa.CONCLUSION: The in-creased expression of Kir 6.1 and SUR2B in colonic smooth muscle cells may be a defensive response to chronic WAS.H2 S donors may have potential clinical effect on treating chronic stress-induced colonic hypermotility.

Objective To compare the clinical outcome of intramedullary nail with locking plate in the treatment of two-part proximal humerus fractures.Methods PubMed,SpringerLink,EMBASE,The Cochrane Library,Medline,Science Direct,CNKI,Wanfang Data and VIP database were searched for relevant studies comparing intramedullary nailing and locking plate fixation of two-part proximal humerus fractures.A meta-analysis of the two methods was conducted using the RevMan 5.0.Differences between the two methods were compared with respect to operation time,intraoperative bleeding,bone union time,Constant score and postoperative complication incidence.Results Seven studies were included in the meta-analysis,with 136 patients treated with intramedullary nail and 159 patients treated with locking plate.Intramedullary nailing showed advantages over locking plate fixation with regards to operation time (WMD =-27.71,95% CI-36.07--19.35,P < 0.05),intraoperative blood loss (WMD =-114.18,95% CI-169.91--58.45,P < 0.01) and bone union time (WMD =-2.91,95% CI-5.80--0.01,P < 0.05).While the two methods showed no significant differences in Constant score (WMD =-2.84,95 % CI-5.90--0.22,P > 0.05) and postoperative complication incidence (OR =0.89,95% CI 0.43-1.84,P > 0.05).Conclusion Intramedullary nail is superior to locking plate in operation time,intraoperative blood loss and bone union time for the treatment of two-part proximal humerus fractures,but the two methods are similar in Constant score and postoperative complications rate.
