Objective To investigate the surgical treatment strategies and prognostic factors of cT4bM0 primary rectal cancer.Methods The clinical data of 53 patients with cT4bM0 primary rectal cancer who were admitted to the First Hospital of Peking University from January 2000 to December 2010 were retrospectively analyzed.All the patients received en-bloc multivisceral resection and postoperative chemotherapy.The survival and prognostic factors were analyzed.The patients were followed up via out-patient examination,phone call or mail,and the follow-up was ended till December 2012.The survival curve was drawn using the Kaplan-Meier method,and the survival was analyzed using the Log-rank test.Uni-and multivariate analysis were done using chisquare test and COX's proportional hazard model.Results Of all the 53 patients,20 received posterior pelvic exenteration (PPE),20 received total pelvic exenteration (TPE),3 received low anterior resection (LAR) +local resection of ballder,2 received LAR + ovariectomy,2 received LAR + local resection of ureter,1 received LAR + local resection of posterior vaginal wall,1 received LAR + vesiculectomy and vesectomy,3 received abdominoperineal resection (APR) + local resection of posterior vaginal wall,1 received APR + sacrectomy.R0 resection was achieved in all the patients.No intraoperative death was observed,and the incidence of postoperative complication was 9.4％ (5/53).The results of postoperative pathological examination showed that 2 patients were with well-differentiated adenocarcinoma,41 with moderate-differentiated adenocarcinoma,and 10 with poorly differentiated adenocarcinoma.Twenty-four patients were with lymph node metastasis.Four patients were in TNM stage Ⅰ,25 in TNM stage Ⅱ and 24 in TNM stage Ⅲ.Fifty-three patients were followed up postoperatively,and the median time for follow-up was 33 months (range,4-116 months).The overall 5-year survival rates was 57.3％.The 5-year survival rate for patients with or without lymph node metastasis were 77.1％ and 30.4％,respectively,with significant difference between the 2 groups (x2 =7.374,P ＜ 0.05).The 5-year survival rates of patients with malignant infiltration and inflammatory adhesion mere 51.0％ and 68.5％,with no significant difference (x2=1.148,P ＞0.05).The 5-year survival rates of patients with malignant infiltration and inflammatory adhesion in stage Ⅱ were 74.6％ and 85.7％,with no significant difference between the 2 groups (x2=0.118,P ＞ 0.05).The 5-year survival rates of patients with malignant infiltration and inflammatory adhesion in stage Ⅲ were 28.8％ and 37.5％,with no significant difference between the 2 groups (x2 =0.959,P ＞ 0.05).The results of univariate analysis showed that lymph node metastasis and TNM stage were the risk factors influencing the prognosis of patients with cT4bM0 primary rectal cancer (x2=6.468,6.596,P ＜ 0.05).The results of multivariate analysis showed that lymph node metastasis was the independent risk factor (RR =3.797,P ＜ 0.05).Conclusions En-bloc multivisceral resection should be the first surgical treatment choice for patients with cT4bM0 primary rectal cancer,and lymph node metastasis is the independent risk factor.Under the same N stage,the prognosis of patients with malignant infiltration or inflammatory adhesion is similar if R0 resection is achieved.

ObjectiveTo explore the clinical diagnosis and surgical treatment of primary retroperitonealneurilemoma(schwannoma). MethodsClinicaldataof 47patientsof primary retroperitoneal schwannoma admitted and surgically treated from January 1995 to December 2009 were retrospectivelly reviewed.ResultsAs diagnosed by pathology there were 36 cases of Benign schwannoma,with a median age at onset of 41years, among those 11 patients were symptomatic, and 25 were asymptomatic. There were 11 malignant 11 cases, the median age was 38 years, among those 6 patients were symptomatic, and 5 were asymptomatic. The positive diagnostic rate of preoperative CT and MRI were 36. 2％ ( 17/47 ) and 58. 3％ ( 7/12 ) respectively. Immunohistochemically positive rates of S-100 were 100％ and 81.8％(9/11) in benign and malignant group respectively.All cases underwent surgical treatment. Surgical resection rates for benign and malignant groups were 100％ and 90. 9％(10/11)respectively. There was no perioperative death, Overall 5-year survival rates were 100％ and 45.5％ for benign and malignant tumors groups respectively. In benign group 2 cases recurred, in malignant group 4 cases recurred, and 3 had distant metastasis.ConclusionsPrimary retroperitoneal schwannomas are less common. It is difficult to make an accurate preoperative diagnosis. Surgery is the most effective therapy.Prognosis is good for benign and poor for malignant retroperitoneal neurilemomas.

Aim To provide an electrophysiological basis for hippocampus involved emotional changes caused by tinnitus, the effects of salicylate on electro-physiological characteristics of the voltage-gated calci-um channels in hippocampal neurons were performed. Method The effects of salicylate on voltage-gated cal-cium channels in rat hippocampal neurons were stud-ied, using the whole-cell voltage clamp method. Re-sults Salicylate blocked the voltage-gated calcium channels ( ICa ) in a concentration-dependent manner (0.1~10 mmol · L-1 ) . The half-inhibition concen-tration ( IC50 ) values for the blocking action of salicy-late on ICa were 1.64 mmol·L-1 . With 1 mmol·L-1 salicylate applicalted into bath solution, the steady-state activation curve of calcium channel was shifted by about 9 mV in the hyperpolarizing direction, and its steady-state inactivation curve was not changed. Con-clusion Salicylate inhibits ICa in rat hippocampal neu-rons and significantly affects the activation kinetics of ICa ,which could be related to emotional changes caused by tinnitus.

Objective To explore the impacts of natural ovulation cycles and stimulation cycles on the outcome of intrauterine insemination (IUI) in order to improve the clinical effects of IUI. Methods 176 women received 384 stimulation cycles. According to different ovulation stimulation protocols , the women were divided into six groups including natural cycle (NC) group, clomiphene citrate (CC) group, letrozole (LE) group;human menopausal gonadotrophin (HMG ) group, CC + HMG group, and LE + HMG group. The pregnancy rate between nature cycles and ovarian hyperstimulation cycles was compared. Results The pregnancy rate was 9.33%in the nature cycle group and 13.27% in the stimulation cycle group, with a significant difference (P < 0.05);and it dif not differ significantly among the stimulation cycle groups (P > 0.05). Conclusions Use of ovulation-induction medications is one of the important factors affecting the pregnancy rate of intrauterine insemination. There are no differences in the outcome of IUI among different ovulation stimulation protocols.
