OBJECTIVETo study the applied value of double joystick technique in reduction-internal fixation for femoral shaft fracture in adults.

METHODSThirty-four patients (24 males and 10 females) with femoral shaft fractures were treated with reduction assisted by double joystick technique and internal fixation with interlocking intramedullary nail from September 2010 to June 2013. The average age of the patients was 41 years old, ranged from 17 to 65 years old. The duration of the disease course ranged from 3 to 7 days, with a mean of 5 days. The fractures belonged to AO types 32A (5 cases), 32B (20 cases) and 32C (9 cases) and located in left femur for 18 patients and right femur for 16 patients. The patients were followed up, and fracture healing and complications were observed. The curative effect were evaluated according to Thorsen femur fracture evaluation standard.

RESULTSThe operative time ranged from 40 to 110 min (mean 75 min) and intraoperative blood loss ranged from 200 to 300 ml (mean 250 ml). All the patients obtained a good fracture reduction and were followed up for 12 to 24 months (mean 18 months) after the surgery. All the fractures united between 4 and 8 months with a mean of 5 months. No complications such as breakage of nail, infection, osteofascial compartment syndrome, refracture and fracture malunion were found. According to Thorsen femur fracture evaluation standard, 30 patients obtained an excellent result, 3 good and 1 fair.

CONCLUSIONIn surgery of reduction-internal fixation for femoral shaft fracture in adults, the use of double joystick technique obtains good reduction result, short operative time, less injury, high healing rate of bone fractures, less complications and good limbs function, so it is worthy of popularizing in clinic.

AIM:To investigate the roles of ClC-3 chloride channels in the regulation of cell cycle and the re-lationship between ClC-3 chloride channels and the cell cycle regulators , such as cyclin D1, cyclin-dependent kinase (CDK)4, CDK6, P21 and P27 in the HeLa cells.METHODS:ClC-3 genes were silenced by the siRNA technique in the HeLa cells.The transfection efficiency of ClC-3 siRNA was detected by real-time PCR.The cell cycle distribution was ana-lyzed by the flow cytometry .The protein expression of ClC-3, P21, P27, CDK4, CDK6 and cyclin D1 was determined by Western blot .RESULTS:ClC-3 was knocked down by ClC-3 siRNA in the HeLa cells .Transfection of the cells with ClC-3 siRNA arrested the cells at G0/G1 phases, decreased the expression of cyclin D1, CDK4 and CDK6, and increased the expression of P21 and P27.CONCLUSION:ClC-3 plays an important role in the cell cycle of HeLa cells through the G 1-S transition point.ClC-3 may regulate the cell cycle progression by up-regulation of cyclin D1, CDK4 and CDK6 expression and/or by down-regulation of P21 and P27 expression.

Objective To study the safety and feasibility of tubeless percutaneous nephrostolithotomy by hemostasis gel closure of mini-percutaneous renal-channel.Methods Eighty patients after conventional percutaneous nephrostolithotomy are selected and divided into two groups according to the principle of randomization.Control group adopts conventional percutaneous nephrostolithotomy calculi lithotripsy with renal pelvis drainage tube placement whereas the experimental group adopts tubeless percutaneous nephrostolithotomy by hemostasis gel closure of mini-percutaneous renal channel.Both experimental group and control group will be scientifically and statistically analyzed via the incidence and the dose of using sedative for alleviating pain after operation,hospital stay,level of hemoglobin,and the occurrence of complications such as continuate hemorrhage,infection,urinary extravasation,etc.Results The operation of both groups are successful in phrase Ⅰ.The incidence and the dose of using sedative in control group are obviously higher than that in experimental group(45％ vs 20％).However,the incidence of postoperative complications like infection and hemorrhage and hospital stay between two groups are undifferentiated in statistics(P ＞ 0.05).Neither the experimental group nor the control group has perinephric hematoma,and seven cases of control group have urinary leakage after remove of fistula.Conclusion Tubeless percutaneous nephrostolithotomy by hemostasis gel closure of mini-percutaneous renal-channel is safe and feasible and it can reduce the incidence of postoperative pain and avoid urinary leakage.

Objective To evaluate mini-percutaneous nephrolithotomy in treating superior segmental ureteral calculi. Methods Two Hundred and thirty-six patients underwent mini-percutaneous nephrolithotomy with holmium laser for superior segmental ureteral calculi from May 2005 to May 2008, 133 male and 103 female. Their age ranged from 17 to 76 years old with a mean of 47. 2 years. Of the 236 patients,141 compli-cated with calculi in the left side and 88 cases in the right side,7 in the both sides. The calculi diameter ranged from 0. 7 cm to 2.2 cm and the mean diameter was 1.4 cm. One hundred and ninety-three patients had undergone ESWL from 1～6 times. Results Of the 236 patients,217 were rendered stone-free at 1 pro-cedure. Residual calculi were found in 12 cases after operation and drugs were used for treatment. The resid-ual calculi were removed after 1 month. Seven cases with residual calculi were treated by ESWL and the cal-culi were removed. The total stone clearance was 91.9%. The mean operation time was 31.3 min(rang from 19～52 min), and the mean hospital stay was 9.5 days(rang from 6 to 12 days). The main complications following operation included: durative hematuria in 25 cases relieved by haemostasis and diuresis treatment within 24 to 48 hours,pnstoperative fever in 141 cases within 24 hours of which 103 were relieved by antiin-flammatory and fluid replacement treatment within 24 to 48 hours. Thirty-eight cases were relieved by anti-inflammatory treatwent depending on urine culture results within 3 to 7 days. The postoperative pain in all patients was light. Conclusion Minimally invasive percutaneous nephrolithotomy with holmium laser under ultrasound guidance is simple,safe and effective in treating proximal ureteral calculi.

Objective: To observe the clinical efficacy of Maren Soft Capsule on treating constipation in stroke patients. Methods: Patients (104) suffered from constipation were randomly divided into the treatment group (n = 52) and the control group (n = 52). Patients in the treatment group were given Maren Soft Capsule and Maren Boluses were used to the patients in the control group. Results: In two weeks after treatment, the defecation frequency and stool consistency were observed and compared between the two groups. Compared with the control group, defecation frequency and stool consistency scores were higher in the observation group, the differences were statistically significant (P < 0.05). The total efficacies in the control group and observation group were 69.23% and 96.15%, respectively, the differences were statistically significant (P < 0.001). No serious adverse reactions were found in the two groups. Conclusion: Maren Soft Capsule could solve the constipation in stroke patients.

Objective To investigate the association of two single nuclear peptides(SNPs)polymorphisms(rs11209026 and rs11805303)which lies in interleukin-23 receptor(IL23R)gene with susceptibility to inflammatory bowel disease(IBD).Methods The target SNPs were directly sequenced by polymerase chain reaction(PCR)and gene polymorphisms of 50 healthy and 81 patients with IBD (Crohn's disease in 41 patients and ulcerative colitis in 40 patients)were analyzed using chromassoftware.Results The geno-type frequency and allelic frequency of rs11209026 were 7.3%and 3.7%in patients with Crohn's disease respectively,15.0%and 7.5%in patients with ulcerative colitis respectively as well as 14.0%and 7.0%in normal population respectively(all P value＞0.05).The geno-type frequency and allelic frequency of rs11805303 were 22.0%and 52.4%in patients with Crohn's disease respectively,15.0% and 41.2% in patients with ulcerative colitis respectively as well as 34.0%and 59.0%in normal population respectively(all P value＞0.05).But in allelic frequency there was significant difference between ulcerative colitis patients and normal population(P=0.018).The polymorphisms of rs11805303 loci did not correlate with age,gender,disease duration.activity and site in patients with ulcerative colitis.Conclusions IL23R gene polymorphism is not associated with the susceptibility to Crohn's disease.rs11805303 allele may be related with susceptibility to ulcerative colitis.But no correlation was found between the SNP polymorphisms and the clinical characteristic of ulcerative colitis.
