[Objective] To evaluate the therapeutic effect of closed bone-breaking therapy for malunion of traumatic fracture of femoral shaft. [Methods] Fifty-six patients with malunion of traumatic fracture of femoral shaft were treated with closed bone-breaking therapy combined with splint fixation, traction, Chinese herbal medicine and dirigation. After 6 months of treatment, the curative effect was evaluated with criteria of therapeutic effect grading and the patients were followed up after one year. [Results] Among 56 cases, 31 (55.4%) were cured, 20 (35.7%) markedly effective and 5 (8.9%) effective, the total effective rate being 91.1% . [Conclusion] Closed bone-breaking therapy combined with splint fixation, traction, Chinese herbal medicine and dirigation is effective in treating malunion of traumatic fracture of femoral shaft with fast restoration, good apposition, less pain and complications. This method is simple, cheap and practicable. However, attention should be paid to the practice of bone-breaking operation: before operation, the indications of deformity influencing function, and bone-breaking therapy being beneficial to the union of fracture should first be taken into consideration; during the operation, the manipulation should be gentle and accurate, damage to soft tissue, blood vessels, nerves and joints should be avoided; after operation, good reduction, splint fixation and traction should be done.

Objective To explore treatment of bile duct variation in Laparoscopic Cholecystectom.Methods The author retrospectively analyzed the clinical data of 7 cases with bile duct variation in 2 000 patients performing Laparoscopic Cholecystectomy.Among the 7 cases,2 cases had small hepatic duct openings in the gallbladder bed;2 cases had cystic duct openings in the right hepatic duct;2 cases had accessory right hepatic duct;and one case had rare variation whose right hepatic bile duct and the jejunum connect together.2 cases of the first variation had no bile leakage,adopting the suture method in LC.Among 2 cases of the second variation(all found in LC),one case had bile spillage in the junction of the cystic duct and the right hepatic duct,so the operator converses to laparotomy,cuts the gallbladder,sutures the break,and the patient had no bile leakage at last;The other one case was anatomized clearly under the cavity mirror.Among 2 cases of the third variation,one had no bile leakage,whose accessory hepatic duct was ligated in LC.The other one case had bile leakage after LC,so the operator converses to laparotomy,clips the accessory hepatic duct,and extract the drainage tube until there was no bile drainage.The last case was mistaken and cut it,the next day biliary peritonitis appeared,so the bile leakage was sewed up under the laparoscope.Results The seven cases were followed 1 ~3 years,they had no jaundice and their liver function was normal.Conclusion Careful-ly dissect Calot's triangle in LC,observe bile leakage after LC;improve the level of understanding and dealing bile duct variation in LC,don't cut the duct which is known to us.We should treat differently according to particular case.

Objective To study the effects of whole-body irradiation(WBI)with different doses of X-rays on apoptosis in mouse splenocytes and peritoneal macrophages.Methods The apoptosis percentages of mouse splenocytes and peritoneal macrophages were detected with flow cytometry(FCM)at different time after the whole-body X-irradiation using the staining of Annexin-V and PI.Results As compared with the control,the percentage of apoptosis in mouse splenocytes began to increase gradually 24 h after WBI with 2 Gy X-rays(P

Objective To analyze the impact of allograft category on the result of living related donor kidney transplantation (LRKT)and to evaluate the predominant donors. Methods A retrospective analysis of 104 recipients receiving LRKT from Apr. 2004 to Mar. 2008 was performed. Based on donor resource, all the recipient-donor pairs were divided into four groups: spousal donation group,parental donation group, sibling donation group and cousinly donation group. The observational parameters were selected for analysis, such as average post-transplant hospitalization dates, time for serum creatinine (Scr) back to normal level, Scr levels of every observational time point, incidence of major complications (infection, rejection, DGF) and recipient/graft survival rate. Results Recipient/graft survival rate of sibling donation group seemed higher. Recipients of sibling donation group seemed to have fewer post-transplant hospitalization dates, but higher rates of infection, while those of parental donation group seemed to have higher rates of rejection. Rates of rejection and infection of spousal donation group were lower than supposed. There was no statistically significant difference in time for Scr back to normal level and Set levels of every observational time point among these four groups. Conclusions The result of sibling donor renal transplantation is better, while short-term outcome of spouse donor renal transplantation is ideal, which is similar with parent or cousin donor renal transplantation. Except for human leukocyte antigen, aspects such as quality of donor kidney, predominance during operation and self-administration post-transplant are also the guarantee for the success.

Objective To analyze the relationship between the genetic polymorphisms of organic anion transporting polypeptide (SLCO1B1 and SLCO1B3) and mycophenolic acid ( MPA)pharmacokinetics in Chinese kidney transplant recipients. Methods Gene mutations (SLCO1B3T334G, SLCO1B1 A338G) were detected in 68 recipients by PCR-LDR. The plasma samples were collected and blood concentration of MPA was measured on the 28 th day after transplantation. The area under the curve (AUC)0-12 of MPA in different genotype recipients was compared to analyze the correlation between single nucleotide polymorphisms (SNPs) and MPA pharmacokinetics. Results MPA AUC0-12 was higher in SLCO1B3 T334G GG carriers group than in TT carriers [(54. 54 ±14.40)vs(37.30±12.88)mg·h·L-1,(P=0.052)].However,there was no difference in MPA AUC0-12 among each genotype of SLCO1B1 A338G (P>0. 05). Conclusion Genetic polymorphisms of SLCO1B3 affect interindividual variety in plasma MPA concentration in Chinese kidney transplantation recipients.

Objective To investigate the change and implication of plasma osteopontin (OPN) levels in renal allograft rejection.Methods The clinical data and biological samples of 46 renal transplant recipients were analyzed rerrospecnvely,including 16 patiens with stable allograft function and no evidence of biopsy-proved rejection (Non-R),22 patients with biopsy-proved acute cellular rejection (ACR),and 8 paients with biopsy-proved chronic allograft nephropathy (CAN).Six living related donors served as healthy controls (HC).Plasma OPN level was determined by using the human OPN ELISA kit.Type and grade of ACR were diagnosed based on Banff 03 classification criteria of renal allograft pathology.The plasma OPN levels were compared among different groups.The assistant diagnostic value of plasma OPN levels in differentiating rejection patients were also evaloated.Results The plasma OPN level in HC,Non-R,CAN and ACR groups was ( 12.23 ±5.95),(19.38±8.23),(27.77± 12.27) and (41.84± 18.51) μg/L,respectively.There was no significant difference in plasma OPN levels among HC,Non-R and CAN groups (P＞0.05),but the OPN levels in ACR group were decreased significantly as compared with Non-R and CAN groups (P＜0.05 ).OPN levels were positively correlated with Banff grading of ACR (P＜0.05).OPN levels were significantly different between grade Ia and grade IIb (P＜0.05).Conclusion The change in plasma OPN level has a relationship with acute rejection.Besides,the plasma OPN levels were also positively correlated with the severity of ACR.Monitoring plasma OPN levels should be useful in predicting and evaluating the severity of ACR in renal transplant recipients.

The methods of 1H Nuclear Magnetic Resonance (NMR) and mass spectroscopy were used in detecting the metabolites of brodimoprim (BDP) in rat plasma. The endogenic compounds in the plasma were removed with solid phase extraction (SPE) column firstly, then the mixture of metabolites was identified with 1H NMR and mass spectroscopy (MS). Two metabolites of BDP in the plasma at 20h were detected, they were demethyl-brodimorpim glucuronide and brodimoprim sulfurate. The study proved that the method of SPE coupled with NMR and MS can be applied to the analysis of metbolites in plasma quickly and conveniently.

AIM: To investigate the effects of in situ transplantation of mobilized autologous bone marrow stem cells on infarction size and cardiac function in patients with acute myocardial infarction. METHODS:25 patients with first acute myocardial infarction were randomly divided into stem cells in situ transplantation group and control group, 12 patients in stem cells in situ transplantation group were injected subcutaneously with 300 ?g granulocyte colony-stimulating factor(G-CSF) daily for four days in addition to standard therapy. 13 patients in control group were treated with standard therapy alone. The conventional 12 leads electrocardiogram were recorded on 1, 28 days after admission and the cardiac function was scored by the QRS scoring system proposed by Wagner. Furthermore, the infarction size was assessed by radionuclide myocardial perfusion imaging 7, 28 days after admission. RESULTS:4 weeks after admission, the QRS scores decreased, the infarction size reduced significantly in the stem cells in situ transplantation group (from 36.0%?8.3% to 18.0%?5.8%, P
