Objective To measure the effect of tetrandrineon (Tet) on inflammatory mediators and endogenous neural stem cell proliferation after spinal cord injury (SCI) in rats.Methods A total of 162 Wistar rats were separated into injury group,Tet group and sham operation group according to the random number table,with 54 rats per group.Allen' s method was used for induction of experimental SCI.Animals in Tet group were given Tet (22.5 mg/kg) through the tail vein at 30 min,24 h and 48 h postinjury.The same volume of normal saline was given to other two groups.Spinal cord tissue samples were taken from the rats after injury to measure levels of tumor necrosis factor (TNF)-α,interleukin (IL)-1 β and IL-10,and tissues were examined with HE staining and Nestin immunohistochemistry staining.Results Levels of TNF-α,IL-1 βand IL-10 in injury and Tet groups increased compared to these in sham operation group at 6 h,12 h,1 d,3 d,5 d and 1 week postinjury (P ＜ 0.05).At the same time point,level of IL-10 was higher in Tet group than in injury group,but inversely for TNF-α and IL-1 β (P ＜ 0.05).More Nestin-positive cells were present in injury and Tet groups than in sham operation group at 1 d,3 d,1 week,2 week,3 week and 4 week postinjury (P ＜ 0.05).Additionally,more Nestin-positive cells were found in Tet group than in injury group at 1 d,3 d,1 week,2 week and 3 week postinjury (P ＜ 0.05).Conclusion Tet is effective to relieve inflammatory reaction,increase neural stem cell number and promote neurological recovery after SCI.

Objective To discuss the effect of tetrandrine on endogenous neural stem cell proliferation and differentiation after spinal cord injury in rats. Methods 78 rats were randomly divided into 3 groups: control group(n=36), Tet-treated group(n=36), sham-operated group(n=6). Control group and Tet-treated group were adapted with Allen's combat modeling method. Rats in Tet group were injected Ted with a dosage 22.5 mg/kg in 30 minutes, 24 hours and 48 hours after ASCI, and the same dose of saline was injected into injured group as control .Samples were dissected from the spinal cord injury sites at 1 day, 3 days, 1 week, 2 weeks, 3 weeks, 4 weeks after ASCI, and tested by HE staining for morphology and by immunolfuorescence staining for the expression of BrdU and nestin. Results A little Nestin positive cells and BrdU positive cells were found in control group and Tet-treated group at 1 day after injury. A large number of positive cells were found in both groups at 1 week after injury and reached the peak which lasted for 2 weeks and then decreased gradually. The expression of Nestin positive cells and BrdU positive cells in control group and Tet-treated group were decreased significantly at 4 weeks after injury, but were still more than that in sham operation group. The number of Nestin positive cells and BrdU positive cells in Tet-treated group were more than that in control group at each time point after injury. The expression was higher in Tet-treated group than control group at 1 day, 3 days, 1 week, 2 weeks, 3 weeks after injury and had no difference at 4 weeks after injury. Conclusions Tetrandrine could increase the number of Nestin positive cells, BrdU positive cells and endogenous neural stem cells though improving the microenvironment, and it is beneficial for the recovery of spinal cord injury in rats.

Objective To summarize the clinical features,diagnosis and treatment of autologous urologic neoplasms in renal transplant recipients.Methods A retrospective analysis on the clinical data of 25 renal transplant recipients was done in our center.The onset time of new neoplasms was between 29 to 72 months after transplantation,with an average of 48.2 months.Intermittent hematuria was the first symptom in 23 patients,and the rest two cases were diagnosed through routine examination. The pathological diagnoses of thee cases were renal carcinoma,which were treated by transperitoneal laparoscopic radical nephrectomy.Eight cases were diagnosed as having renal pelvic tumor,which was treated by radical resection for the renal pelvic carcinoma.Fourteen cases were diagnosed as having bladder cancer,which was treated by transurethral resection of bladder tumor (13 cases) or radical cystectomy (one case).All patients were subjected to surgical treatment.The dosage of MMF,CSA/Tacrolimus was decreased to 1/2-2/3 of their original dosage. Sirolimus was used in place of calcineurin inhibitors in four patients.Immunosuppressive regimes and adjuvant therapy were given after surgery treatment.Results Twenty-five patients were followed up for 12-84 months.Contralateral renal carcinoma combined with lung and chest multiple metastases occurred in one case after radical nephrectomy,who died after targeted therapy 6 months later.Two patients with lymph node metastasis died 14 months and 20 months after surgery respectively.The rest 22 patients were closely followed up,whose creatinine remained 98-163μmol/L.Conclusion More attention should be paid to patients with hematuria after renal transplantation to screen the autologous urinary neoplasms.Patients should be treated with surgical procedures,and immunosuppressive regimens should be adjusted postoperatively.

OBJECTIVETo search for the optimal strategies for sperm collection from the patient with temporary penile erectile dysfunction (ED) on the day of oocyte pick-up ( OPU) in in vitro fertilization embryo transfer (IVF-ET).

METHODSWe retrospectively analyzed 93 cases of temporary ED on the OPU day of IVF-ET from January 2011 to May 2014, with fresh semen for 45 cases (group A), cryopreserved sperm before oocyte retrieval for 30 cases (group B), and frozen oocytes for 18 cases (group C). Group A was again subdivided into A1 (n = 18) and A2 n = 27) , the former intervened with oral sildenafil while the latter left untreated. We compared the rates of fertilization, high-quality embryo, and pregnancy among different groups.

RESULTSNo statistically significant differences were found among groups A, B and C in the age of the males and females, duration of infertility, numbers of obtained and mature oocytes, and rates of cleavage, or in the percentages of normal fertilization (80.78% vs 80.43% vs 84.77%), high-quality embryo (53.27% vs 52.97% vs 47.69%) and pregnancy (60.00% vs 56.77% vs 44.44%) (all P > 0.05). The rate of 3PN was markedly lower in group C (0.63%) than in A (9. 61%) and B (4.34%) (P < 0.05). There were no significant differences between groups A1 and A2 in the age of the males and females, duration of infertility, numbers of obtained and mature oocytes, and the rates of fertilization, cleavage, high-quality embryo, and pregnancy (all P > 0.05).

CONCLUSIONOn the OPU day of IVF-ET, oral sildenafil can help temporary ED men to achieve penile erection and ejaculation without affecting the outcomes of assisted reproduction. Cryopreserved sperm can be used in case of predicted temporary ED and frozen oocytes can also be employed if sperm retrieval fails. However, to avoid puncture injury to the epididymis or testis, fresh semen should be the first choice.

Objective: To study the methylation state within MAGE 1 B′B promoter in gastric carcinoma and the association between demethylation and pathological differentiation, the association between demethylation and clinical stage. Methods: Using methylation sensitive restriction analysis followed by polymerase chain reaction (PCR),we studied 80 specimen that were obtained from surgical samples (including 40 gastric carcinoma and 40 matched adjacent normal gastric mucosae).Results: An demethylation state was identified in DNA from gastric carcinoma specimens.The demethvlation rate is 25%(10/40).In contrast,no demethylation state was identified in DNA from matched adjacent normal gastric mucosae. The differences were Significant statistically. ln our study, the demethylation in poorly, moderately, and well differentiated glandulous cell carcinoma were detected at frequencies of 50%,18.7% and 8.3%,respectively, The differences were significant statistically ( P

Objective To summarize the clincical experience of transumbilical Laparoendoscopic Single-site (LESS) nephrectomy and to evaluate its safety and efficacy. Methods From December 2008 to August 2010, we have performed 20 cases of transumbilical LESS nephrectomy by Tri-Port system, of which 9 patients underwent LESS radical nephrectomy (left 8, right 1, stage T1 ), 1 patient underwent LESS radical resection of right ureteral carcinoma, 10 patients underwent LESS simple nephrectomy (left 5, right 5). The Tri-Port system was inserted transperitoneally through a 2 cm umbilical incision. A 5-mm 30° telescope was introduced through the port to visualize the operative field. Flexible equipment and standard laparoscopic equipment were used to perform the procedures.The incisions were extended to about 6cm in order to remove the specimens. Results Conversion to open surgery was necessary in one LESS radical resection of right ureteral carcinoma and one LESS simple nephrectomy, while the remaining 18 cases were successful (the addition of a single 5-mm port was necessary in 2 cases of LESS radical nephrectomy). The mean operative time was 197 min (85-510 min), mean estimated blood loss was 126 ml (50-400 ml), without blood transfusion in the perioperative period, mean postoperative hospital stay was 6.3 d (3-14 d), and mean duration of catheter drainage was 3.6 d (0- 14 d). Conclusions Transumbilical LESS nephrectomy is feasible, safe,minimally invasive and cosmetic. Long-term follow-up and a clinical control study are needed for evaluating clinical outcomes.

OBJECTIVE: Meta-analysis was used to compare the clinical efficacy of high tibial osteotomy(HTO) and unicondylar arthroplasty (UKA) in the treatment of medial compartment osteoarthritis (MIOA) and provide a better surgical choice for patients with MIOA. METHODS: The Cochrane Library (Issue 6, 2017), PubMed, Ovid, ELSIVE, CNKI and Wanfang databases were searched by a computer. Literatures on HTO and UKA for MIOA from January 1, 1970 to June 30, 2017, including complications, knee joint score, knee mobility, revision rate and excellent and good rate, were searched and screened out according to the inclusion criteria, and strict quality evaluation was carried out. RevMan 5.0 software provided by Cochrane collaboration network was used to conduct the meta-analysis of the included research results and to test the heterogeneity of the data. RESULTS: Total 13 articles met the inclusion criteria, and the total sample size was 1 043. Among them, 462 were HTO treatment group and 581 were UKA treatment group. By comparison between HTO treatment group and UKA treatment group, there were significant differences in the contralateral deterioration rate[WMD=3.21, 95%CI(1.13, 9.10)], pre-operative knee range of motion[WMD=6.55, 95%CI(1.44, 11.66)], Lysholm knee score[WMD=-3.15, 95%CI(-4.77, -1.53)], complications[WMD=2.78, 95%CI(1.52, 5.11], revision rate[WMD=1.81, 95%CI(1.17, 2.80)], the rate of excellent and good[WMD=0.49, 95%CI(0.30, 0.80)], and femorotibial angle changes[WMD=-2.37, 95%CI, (-3.63, -1.11)](<0.05). There were no significant differences between the HTO treatment group and the UKA treatment group in patellofemoral deterioration rate[WMD=1.59, 95%CI(0.65, 3.84)] and the free walking speed[WMD=-0.02, 95%CI(-0.09, 0.04)](>0.05). CONCLUSIONS Based on the limited data, high tibial osteotomy is a better choice for the treatment of medial compartment osteoarthritis in the comparison of short and medium-term clinical outcomes, and long-term clinical outcomes may need further study.

OBJECTIVETo investigate the association of gene polymorphism of cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) with ulcerative colitis (UC) in Chinese.

METHODSOne hundred and seventeen patients with UC and 246 healthy controls were genotyped for the polymorphisms of C-658T in the promoter and C61T at the 3' untranslated region of the CTLA-4 gene using polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) and polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP), respectively. The genotype and allele frequencies of the two groups were calculated and compared by chi square test.

RESULTSThe frequency of TT+CT genotype at the CTLA-4 gene C-658T in the promoter was significantly higher in UC patients than that in healthy controls (P=0.015). The frequency of the T allele at this locus was also significantly higher in UC patients than that in the controls (P=0.033). The frequencies of TT genotype and T allele at the C-658T locus were highly associated with extensive colitis in UC patients (P=0.037, and P=0.0067, respectively).

CONCLUSIONThe T allele of CTLA-4 promoter C-658T locus was highly associated with UC in Chinese Han of central China.

OBJECTIVETo study the mechanism of Ca(2+) on the apoptosis induced by hyperthermia in neonate rat hippocampal neurons to provide the applicative evidence of dantrolene for preventing brain injuries.

METHODSDantrolene, Ca(2+) specific blocking agent, was used in the hyperthermia-induced apoptosis of primary hippocampal neurons in vitro to observe its effect on the apoptosis, fluorescent intensity, and dynamic change of Ca(2+) by flowcytometry and laser confocal microscopy.

RESULTSThe rate of apoptosis was decreased significantly after hyperthermia treatment by dantrolene sodium. The intracellular Ca(2+) fluorescent intensity in 42 degrees C treatment group (107.35 +/- 6.0) was significantly lower than that in control group (159.12 +/- 33.8). The concentration of Ca(2+) began to decrease 20 approximately 25 s after adding dantrolene sodium, and reached the lowest level about 50 s later, and then kept lower than the basal level.

CONCLUSIONDantrolene sodium has an important protective effect on hippocampal neurons apoptosis induced by hyperthermia and may have some applicative value of preventing heat-induced brain injury.
