ObjectiveTo compare the clinical effects of extracorporeal shock wave lithotripsy (ESWL) and ureteroscope holmium laser lithotripey(URL) in emergency patients with ureteral calculi.MethodsTwo hundred and forty emergency patients with ureteral calculi were retrospectively analyzed,including 110 patients undergoing ESWL (ESWL group) and 130 patients undergoing URL (URL group).Results The success rate of fragmentation and calculi-free rate were 90.0％ (117/130) and 80.8％(105/130) in URL group,of which were 88.2％(97/110) and 75.5％(83/110) in ESWL group with no significant difference between two groups (P ＞ 0.05 ).The success rate of fragmentation and calculi-free rate of upper ureter in ESWL group were much better than those in URL group[93.1％(54/58) vs.84.3％(59/70),77.6％ (45/58) vs.70.0％ (49/70),P ＜ 0.05 ],those of middle-lower ureter in URL group were much better than those in ESWL group[96.7％(58/60) vs.82.7％(43/52),93.3％(56/60) vs.73.1％(38/52),P＜0.05].ConclusionESWL and URL both have good curative effects in emergency patients with ureteral calculi,and ESWL has better effects for upper ureter while URL for middle-lower ureter.

Objective To study two different methods in treatment of primary pterygium surgery on corneal epithelial wound repair and the influence on the recurrence rate.Methods Used prospective controlled study,accord-ing to a number table 128 patients with 128 eyes were randomly divided into control group (64 cases),and observa-tion group (64 cases).The two groups of patients underwent pterygium excision and limbal stem cell transplantation. The observation group (64 eyes)received 0.2 mg/mL mitomycin C of mitomycin -C(MMC)adjuvant therapy. Corneal epithelial wound repair speed was observed.The patients were followed up for 6 -12 months,average 8.5months,the recurrence rate of pterygium was observed in the two groups.Results The grafts were smooth,and the conjunctival flap healed well in the two groups.The postoperative corneal epithelial healing time of the control group and the observation group were (2.13 ±0.37)d,(2.87 ±0.41)d,there was statistically significant difference (t =4.91,P <0.01);The postoperative recurrence rates were 6.25%,4.69% respectively,there was no statistically sig-nificant difference (χ2 =0.48,P >0.05).Conclusion There was no difference in recurrence rate between two kinds of pterygium surgical method,but the combined MMC can cause corneal epithelial healing delay.

Objective To evaluate the efficacy and safety of percutaneous nephrolithotomy(PCNL) by middle renal calice used as main access for the treatment of staghorn stones with the combination of pneumatic and ultrasonic lithotrite.Methods Clinical data of 73 patients underwent PCNL by middle renal calices as main access with 57 incomplete staghorn stones and 35 complete staghorn stones.The rate of stone removal and complications were the main points of the analysis.Results Seventy-two cases underwent first session PCNL by single access tract(middle calices),3 cases underwent first session PCNL by double access tracts (2 cases by middle and lower calices,1 case by upper and middle calices).Of these patients,1 case had fragments with no further treatment,16 cases underwent second session PCNL.All were treated by single access tract (middle calices) and 2 cases had extracorporeal shock wave lithotripsy before the second PCNL.Seventy-six cases composed of 27 complete staghorn stones and 49 incomplete staghorn stones had no residual fragments with the stones removal rate 82.6％ (76/92).Hemoglobin dropped 1-4 g/L,11 cases and 3 cases were given blood transfusion in the operation procedure and post operation respectively.One case developed pyelonephritis and 1 case had split renal dysfunction with peri-parenchyma infection.Conclusions By middle calices as a main access to perform PCNL for staghorn stones is effective and safe.Using pneumatic and ultrasonic lithotrite will be very useful with high stones free rate and short procedure time and less complication.

Aim To investigate the proliferative effect and the apoptosis of rat epididymal epithelial cells induced by podophyllotoxin and its underlying mechanisms.Methods Primary epididymal epithelial cells were cultured in vitro.CCK-8 assay was used to analyze proliferation of epididymal epithelial cells induced by podophyllotoxin on 24, 48 and 72 h.The ultra structural changes of the epididymal epithelial cells were observed by transmission electron microscope.AnnexinV-FITC/PI staining was used to quantify the percentages of apoptosis in the total cell population.The TdTmediated dUTP nick end labeling(TUNEL) technique was applied to observe the morphological changes of apoptotic cells.The expression of tumor necrosis factor alpha(TNF-α) mRNA was investigated by real-time RT-PCR.The level of TNF-α in cell culture supernatant was measured by enzyme-linked immunosorbent assay(ELISA) technology.Western blot was per-formed to determine the protein expression of cytochrome C, caspase-3, caspase-8, caspase-9.Results Podophyllotoxin significantly inhibited the activity of proliferation and induced apoptosis of epididymal epithelial cells in a dose-and time-dependent manner(P<0.05), with a 50％ inhibitory concentration(IC50) value and corresponding 95％ confidence intervals(CI) of 59.36(15.50～227.41), 0.37(0.080～1.70), 0.077(0.017～0.35) μmol·L-1 at 24, 48 and 72 h, respectively.Podophyllotoxin induced cell volume turned round and cell nuclear fragmentation and mitochondrial vacuolation.RT-PCR and ELISA results showed that podophyllotoxin improved the expression of TNF-α mRNA and protein.Western blot results demonstrated that podophyllotoxin activated the protein expression of cytochrome C, caspase-3, caspase-8 and caspase-9.Conclusion Podophyllotoxin can induce rat epididymal epithelial cell apoptosis through both the mitochondria-regulated intrinsic pathway and the TNF receptor-mediated extrinsic pathway.

Objective To summarize the experience in early diagnosis and emergency treatment for combined thoracoabdominal injury (CTI). Methods Clinical data of 58 cases of CTI admitted to our hospital from June 2001 to August 2009 were analyzed retrospectively.All the patients were treated by closed drainage of thoracic cavity,of which 12 cases were treated with thoracotomy,31 with laparotomy,seven with thoracic and abdominal incisions and three with combined thoracoabdominal incision.Internal fixation for long limb bones was performed in 27 cases,spinal laminectomy and pedicle screw fixation in five and amputation in one. Results After operation,six cases were found to have adult respiratory distress syndrome (ARDS) and 12 cases were complicated with multiple organ dysfunction syndrome (MODS).Fifty-three cases were cured and five died. Conclusions CTI based multiple injuries are severe and complicated.CT scan in the early stage plays a significant role in the diagnosis of CTI and closed drainage of thoracic cavity is an important assurance of the security of abdominal operation.Early diagnosis,correct choice of operation procedures and reasonable handling order of injured organs can improve the successful rescue rate for multiple injury patients.

Betacellulin (BTC) is one of "islets regeneration factors" which received more and more attention these years. BTCe is the C-terminal 50-residue region of mature BTC protein and can bind with erbB-1?erbB-4 receptor. It has the same mitogenic activity on cells as the whole section. BTC and BTCe can improve the level of glucose-stimulated insulin secretion (GSIS) during islets culture in vitro though they had no effect on the acute insulin secretion. BTCe also effectively ameliorated the hyperglycemia of STZ-induced diabetic rats by a single plasmid injection into muscle of rats. It is supposed that BTCe promote the proliferation of PDX-1 positive cells or repair some signal transduction pathway. Perhaps the latter is more important.

Objective To establish an allogeneic rat model of endometriosis and to evaluate the effects of gonadotropin-releasing hormone (GnRH) agonist GenSci006 on experimental rat endometriosis. Methods Endometrium from SPF grade donor female SD rats were transplanted onto the abdominal wall of recipient female rats to construct an allogeneic endometriosis model. The rats undergoing sham surgery were divided into the sham group. Three weeks later, the length, width and height of the ectopic endometrium were measured, and the volume of the endometrium (V₁) was calculated before drug administration. The modeling rats were randomly divided into four groups: model group, triptorelin group (0.25 mg/kg), GenSci006-1 group (0.125 mg/kg) and GenSci006-2 group (0.25 mg/kg). Each group had 16 rats and received a single dose of the corresponding drug. The sham group and model group were administered an equal volume of solvent. Three weeks after administration, ectopic endometrium was measured to calculate the volume V₂ and inhibition rate. The effect of GenSci006 on rat uterus and ovarian tissues was assessed by comparing organ coefficients and changes in pathological sections. Enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of serum estradiol (E₂), progesterone (P₄), follicle stimulating hormone (FSH), and luteinizing hormone (LH). Real-time fluorescent quantitative PCR was used to detect the expression of GnRH receptor (GnRHR) mRNA in the hypothalamus and pituitary. Western blot was used to detect the expression of estradiol receptor alpha (ERα), beta (ERβ) and progesterone receptor (PR) in ectopic endometrium. Results Three weeks after administration, compared with the model group, the body weight of rats in the triptorelin and GenSci006-2 groups significantly increased (P < 0.05), while the volume of ectopic endometrium significantly decreased (P < 0.05). Compared with the sham group, the model group showed no significant changes in uterine and ovarian organ coefficients or endometrial thickness (P > 0.05). Compared with the model group, the uterine organ coefficients and endometrial thickness were significantly reduced in the triptorelin and GenSci006-2 groups (P < 0.05). Compared with the sham group, the serum levels of E₂, P₄, FSH and LH in the model group showed no significant changes (P > 0.05). Compared with the model group, the ovarian organ coefficient and serum P₄ levels of rats in the Triptorelin, GenSci006-1, and GenSci006-2 groups were significantly reduced (P < 0.05), while the serum LH levels of rats in the GenSci006-1 group were significantly increased (P < 0.05). However, there were no significant changes in serum E₂ and FSH levels in each group (P > 0.05). Compared with the model group, the expression levels of GnRHR mRNA in the pituitary tissue of rats in the triptorelin and GenSci006-2 groups were significantly downregulated (P < 0.05), with no significantly changes in the hypothalamus (P > 0.05). There were no significant changes in the expression level of GnRHR mRNA in the hypothalamus or the protein levels of ERα, ERβ and PR in the ectopic endometrial tissue in any group (P > 0.05). Conclusion The allogeneic endometriosis rat model is a suitable animal model for screening and evaluating drugs for treating endometriosis. The volume of ectopic endometrium, inhibition rate, uterine and ovarian organ coefficients, and serum E₂ levels may serve as indicators for detecting drug efficacy.
