Objective To study anorectal functional status in patients with lumbosacral spinal cord injury (SCI). Methods A total of 115 patients with lumbosacral SCI (SCI group) and 22 controls (control group) were studied by anorectal manometry. Results The maximal anal resting pressure was (56.7?31.1) mm Hg (1 mmHg=0.133 kPa) in SCI group and (87.2?29.2) mm Hg in control group, with significant statistical difference (P

Objective To evaluate the effect and safety of thymosin combined with biapenem in the treatment of severe lower respiratory tract infection of gram negative bacilli.Methods 54 patients with severe lower respiratory tract infection of gram negative bacilli were randomly divided into study group (group A) and control group (group B),group A was treated with thymosin and biapenem,group B biapenem.All patients were treated for 7 ～ 14 days in a course.The clinical effect,treatment time of biapenem,the bacterial clearance rate and adverse drug reaction betweeen two groups were compared.Results The clinical effective rate of group A and B were 84.6％ and 82.1％,respectively,there was no statistical difference (P ＞ 0.05).Treatment time of biapenem in group A and B was (8.2 ±3.4) days and (13.2 ± 3.6) days,respectively,there was statistical difference (P ＜ 0.05).The bacterial clearance rate of group A and B were 86.7％ and 80.7％,respectively,there was no statistical difference between two groups (P ＞ 0.05).Conclusion The treatment time of thymosin combined with biapenem treatment of gram-negative bacilli severe respiratory tract infection was shorter than that of biapenem alone treatment,and it was safe,effective,and worthy of ciinical application.

Objective To study the outcome of ureterocele trated by open surgery and by endoscopic manipulation. Methods We reviewed 29 cases of ureteroceles, including 16 intravesical ureteroceles and 13 extravesical ureteroceles. 19 cases were treated by open surgery and 10 by endoscopic procedure. Results 11 cases of intravesical ureteroceles and 8 cases of extravesical ureteroceles under went open surgery, The reoperation rate was 18.1% and 12.5%, respectively. 5 cases of intravesical ureteroceles and 5 cases of extravesical ureteroceles underwent endoscopic treatment,the reoperation rate being 40.0% and 80.0% respectively. Conclusions Endoscopic approach might be the primary management for intravesical ureteroceles, but open surgery is a favorable alternative for extravesical ureteroceles.

Objective To investigate the relationship between ?hCG genes expression and the clinicobiological behavior of bladder cancer. Methods RT-PCR method combined with restriction endonuclease analysis was adopted to detect the expressions of ?hCG mRNA and its subtypes in 37 cases of bladder cancer tissues. Results 26 of 37 cancer tissues (70%) were positive for ?hCG mRNA expression. The positive rate was higher in invasive tumor (T 2～T 4,13/14) compared with that in superficial tumor (Ta～T 1,13/23) ( P 0.05). Most of superficial tumors only expressed ?7 gene, while invasive tumor expressed ?7,?5, ?3, or ?8 . Conclusions The positive rate of ?hCG mRNA expression is related to tumor stage. The expression of hCG gene ?5, ?3 or ?8 in addition to ?7 indicates a worse differentiated or advanced bladder tumor.

The effectiveness and safety of ureteroscopic holmium: YAG laser lithotripsy for managing ureteral calculi was evaluated. Ureteroscopic holmium. YAG laser lithotripsy was performed in 168 ureteral calculi (upper 27 cases, middle 33 cases and lower 108 cases). The results showed that the stone-free rate was 92.6% in the upper ureteral calculi, 93.9% in the middle ureteral calculi and 94.4% in the lower ureteral calculi, respectively. The complication rate was 4.8% (8 cases). It was suggested that ureteroscopic holmium: YAG laser lithotripsy is a highly effective and safe treatment modality for managing ureteral calculi.

Objective To explore the relationship between the expression of MDR1 gene in liver cell and the formation of cholesterol calculus in gallbladder.Methods The mRNA expression level of MDR1 gene in liver cell of the cholesterol calculus group and the normal control group were measured through reverse transcriptionpolymerase chain reaction (RT-PCR), and microglobulin ?_2 was used as internal contrast.Results The MDR1 mRNA expression level of the cholesterol calculus group was lower than that of the normal control group(1.30?0.19 vs 2.25?(0.28), P

Objective To evaluate the accuracy of confocal laser endomicroscopy (CLE)in primary bile reflux gastritis (BRG).Methods From November 10th to December 15th,2015 ,55 patients underwent CLE examination and preliminarily diagnosed as BRG with traditional white-light endoscopy were enrolled.CLE score standard was designed.Dixon pathologic score was considered as gold standard. Receiver operating characteristic (ROC)curve was drawn to evaluate the accuracy of CLE score in BRG diagnosis.Sensitivity,specificity and 95 % confidence interval (CI )were calculated.Kappa analysis was performed to assess the inter-observer agreement of CLE score.Results According to Dixon pathologic score standard,29 patients (52.7%)were diagnosed as primary BRG among the 55 enrolled patients. Among the 42 Helicobacter pylori (H .pylori )negative patients,the area under receiver operating characteristic curve (AUC)of CLE in BRG diagnosis was 0.90 (95 %CI 0.81 —1 .00).Taking CLE score over six as the cut-off value for diagnosis,the sensitivity and specificity was 84.00% (95 %CI 65 .35 %—93.60%)and 82.35 % (95 %CI 58.97%—93.81 %),respectively.The Kappa value for inter-observer agreement in BRG diagnosis was 0.60 (95 %CI 0.24—0.95).Conclusion Primary BRG can be accurately diagnosed by CLE in H .pylori negative patients with high sensitivity and specificity.

A new artificial somatic-autonomic neuroanastomosis has been established in male rats with spinal cord injury (SCI). Anorectal manometry and neural retrograde tracing were conducted in this animal model to analyze the mechanisms and the effects on recovery of anorectal function. The left L4 ventral root (L4VR) was intradurally micro-anastomosed to the L6 ventral root (L6VR) to establish the new regenerated neural pathway. Three months later the spinal cord was completely transected at the T9-10 level. Eight weeks later the model rats were randomly divided into two groups. The rats in the group 1 (n=8) were applied for anorectal manometry, and those in the group 2 (n=4) were used for neural retrograde tracing study with fluorogold (FG) and dextran tetramethylrhodamine (TMR). The results of anorectal manometry showed the new reflex pathway could induce rectum to contract and simultaneously electric activity of external anal sphincter (EAS) to become weak or disappearing (indicating synergetic relaxation of EAS). FG and TMR dual labeled neurons with round and elliptical shape were mainly observed in L4 angulus anterior of model rats. The regenerated neural pathways were effective to improve the rectum external sphincter synergetic status and restore the anorectal function.

AIM: To observe the curative effect of Jingshichuan Capsule and to try to explore the therapeutic mechanism. METHODS: Medicines were taken orally. During experimental research an animal model of cholelithiasis was established through feeding guinea pig with food which placed a premium on shaping of cholith. The guinea pigs were divided into the pathologic group, the Jingshichuan group and the control group. The animal was executed after sixties days, the gallbladder was taken out by operation to inspect the shaping of cholith; the blood and the bile was collected to be measured; and parts of the tissue of liver and gallbladder were left for pathologic examination. RESULTS: The rate of clinic cure and the rate of effect of Jingshichuan group were separately 40.0% and 96.9%, which was significantly higher than the control group ( P
