Objective To evaluate the clinical application of gastric tube in radical operation for patients with esophageal or cardial carcinoma. Methods From January 2007 to June 2010,50 patients with esophageal or cardial carcinoma were enrolled. Based on surgical methods, they were divided into the gastric tube group (26 cases) and the traditional way group (24 cases). Among the gastric tube group, 21 patients had esophageal carcinoma,and the other 5 patients had cardial carcinoma,and 1 patient was treated with anastomosis in the left neck, 11 patients with anastomosis in upper aortic arch,9 patients with anastomosis in lower aortic arch and 5 cardial carcinoma patients underwent radical resection. Among the traditional way group, 20 patients had esophageal carcinoma,and the other 4 patients had cstdial carcinoma, 1 patient wastreated with anastomosis in the left neck, 11 patients with anastomosis in upper aortic arch, 8 patients with anastomosis in lower aortic arch and 4 cardial carcinoma patients underwent radical resection. The rate of anastomotic leakage, operation time, and length of stay in hospital of the two groups were observed. Results All surgeries were successfully performed. There was no anastomotic leakage case in the two groups, while there were 3 cases pulmonary infection and 1 case death in the traditional way group. There was no statistical difference in operation time [(175 ± 11) min vs. (182±6) min, t = 1.556, P = 0.072] and length of stay in hospital [(16.8 ±9.8) d vs.(17.0 ± 11.3) d,t = 1.495,P= 0.068] between the gastric tube group and the traditional way group. Conclusion Gastric tube has good value in clinical application with fewer complications and without prolonging operation and hospitalization time, which can surely ameliorate quality of life.

Objective To investigate the effects of diagnosis,surgical treatment of giant esophageal leiomyoma. Method The clinical data of 13 patients with giant esophageal leiomyoma treated by surgical operation from April 2001 to March 2009 were retrospectively analyzed. Results Twelve cases were preoperatively diagnosed by esophagogram and esophagoscopy, 1 case was misdiagnosed. Surgical resection was performed successfully in all 13 patients and no complications such as esophageal fistula and esophageal stenosis were found. Followed up 6 months to 3 years, no recurrence was found among 12 patients with giant esophageal leiomyoma, 1 case with esophageal leiomyosarcoma died of tumor recurrence 10 months after operation. Conclusions Surgical resection is the only effective treatment of giant esophageal leiomyoma.Enucleation of tumor extra-mucosa can be used in most cases. Esophagectomy is available for large tumor or malignant tumor. Treatment by endoscopic and thoracoscopic surgery has some limitations and the indications should be considered strictly.

Objective:To evaluate the efficacy of paroxetine on functional low fever. Methods:Using a randomized and placebo controlled trail, a total of 54 with functional low fever were randomized into paroxetine group and placebo group. In paroxetine group, 28 patients received oral paroxetine 1 tablet (20mg/tablet), one times a day for 8 weeks. There were 26 patients in the placebo. The criteria of assessing the therapeutic efficacy on functional low fever and Hamilton Depression Scale (HAMD; 17 items) were used to assess the therapeutic efficacy at the 4th and 8th weekend respectively.Results:After 8 weeks of treatment, the efficacy rate on functional low fever and antidepression were 78.6%, 82.1% in paroxetine group and 26.9%, 23.1% in the placebo group respectively. There was a significant difference between the two groups (P

Objective To study the influence of clinicopathologic characteristics and surgical treatment of gastric cancer on patients' survival rate.Methods From Apr.1994 to Aug.2005, the data of 759 gastric cancer patients concerning surgical treatment, pathological diagnosis and outcome were collected. Retrospective analysis of the results was made, 3-year and 5-year survival rates were calculated by Kaplan-Meier curve method, univariate analysis was done through Log-rank and multiple factors comparison through Cox regression analysis, and follow-up duration was 4-131 months.Results Single factor analysis indicated that age,tumor location,diameter of tumor, Borrmann type, type of histology, TNM stage, depth of infiltration, lymph node metastasis, liver metastasis, peritoneal dissemination, blood of transfusion during operation, extent of the radical cure of the tumor and excision techniques were significantly influential factors for the prognosis of patients. Cox regression analysis showed that tumor location, diameter of tumor,depth of infiltration, lymph node metastasis,liver metastasis, TNM stage, peritoneal dissemination, blood transfusion during operation, extend of the radical cure of the tumor and excision techniques were independent factors influencing the postoperative survival rate.Conclusion Independent factors influencing the postoperative survival rate include tumor location, diameter of tumor, lymph node metastasis, infiltration depth of the tumor, pathological classification, liver metastasis, peritoneal dissemination, and TNM stage, extent of the radical cure of the tumor, lymphanodectomy techniques and blood transfusion during operation are also important factors.

Objective:To investigate the effect ofGuilong Kechuanning tablets combine with antibiotic drugs on pulmonary infection after chemotherapy in patients with lung cancer,so as to reduce the incidence of pulmonary infection in hospital.Methods:A total of 120 patients with lung cancer complicated with pulmonary infection,who underwent chemotherapy in Baoji Hospital of Traditional Chinese Medicine from August 2013 to August 2015,were selected and randomly divided into control group (n=60) and experiment group (n=60).The control group was treated with Ceftizoxime,based on which,the experiment group was added oral Guilong Kechuanning tablets.The course oftreatment of the two groups was 2 weeks.Inflammation indicators of the two groups were compared before and after treatment,and the clinical effect,hospitalized time,antifebrile time,time significantly reduced of cough and expectoration,disappearance time of lung rales and the pulmonary bacterial clearance rate were observed between the two groups.Results:The total effective rate (91.67％) of experiment group was significantly higher than that(73.33％) of control group (x2=13.121,P=0.004).Before treatment,there were no significant differences in WBC,CRP and NEUT levels between the two groups (P＞0.05);while after treatment,the levels of WBC,CRP and NEUT were all lower than those before treatment in both groups (all P＜0.05),and the levels of WBC,CRP and NEUT in the experiment group were lower than those in the control group(P＜0.05).After treatment,the bacterial clearance rate (99.09％) of the experiment group was significantly higher than that (86.94％) of the control group (x2=54.876,P=0.000).Conclusion:Guilong Kechuanning tablets combined with antibiotic drugs can effectively control the pulmonary infection after chemotherapy in the patients with lung cancer,and can improve the clinical symptoms and inflammatory reaction,which is worthy of clinical application.

Objective To investigate the efficacy of sunitinib in the treatment of patients with imatinibresistant advanced gastrointestinal stromal tumor (GIST).Methods The clinical data of 45 patients with imatinib-resistant advanced GIST who received the treatment of sunitinib (37.5 mg/d) at the First Affiliated Hospital of Sun Yat-Sen University from March 2008 to June 2012 were retrospectively analyzed.The mutation of c-kit and platelet-derived growth factor receptor α (PDGFRα) was detected,and the efficacy of imatinib was assessed after the treatment for 3 months,and factors influencing the survival were analysed.The survival rate was calculated using the Kaplan-Meier method,survival analysis was done using the one-way analysis of variance,and multivariate analysis was done using the COX regression model.Results The median time of treatment with sunitinib for the 45 patients was 11.0 months (range,4-37 months).The complete remission rate,partial response rate,rate of stabilized condition and disease progression rate were 15.6％ (7/45),8.9％ (4/45),46.7％ (21/45) and 28.9％ (13/45) after the treatment with sunitinib for 3 months.All the patients with clinical (imaging) complete remission received surgery for metastatic lesions or B-ultrasound guided ablation for single liver metastasis before the treatment with sunitinib.The most common grade 3 or 4 adverse reactions of sunitinib were hand-foot syndrome and anemia.C-kit and PDGFRα mutational analysis were carried out.C-kit exon 9 mutation was detected in 9 patients,c-kit exon 11 mutation in 21 patients,and no mutation was detected in 12 patients.The median progression-free survival time was 8.0 months (range,4.1-11.9 months),and the median overall survival time was 25.0 months (range,13.4-36.6 months).The results of univariate analysis showed that the primary lesion sites and mutational status of primary lesions were factors influencing the progression-free survival and overall survival (x2=5.967,6.622 ; 7.965,8.765,P ＜ 0.05).The results of multivariate analysis showed that only the mutational status of c-kit of primary lesions was the independent factor influencing the progression-free survival and overall survival (Wald =6.540,7.205,P ＜ 0.05).The progression-free survival and overall survival of patients with c-kit exon 9 mutation and patients with no gene mutation were significantly longer than patients with c-kit exon 11 mutation (x2 =7.965,8.765,P ＜ 0.05).Conclusion Sunitinib with a dosage of 37.5 mg/d could effectively treat patients with imatinib-resistant advanced GIST.A better survival is observed in patients with c-kit exon 9 mutation or with no gene mutation when compared with patients with c-kit exon 11 mutation.

Objective To screen and validate differentially expressed microRNAs in human degenerative nucleus pulposus cells (NPCs) and to predict their target genes,and to investigate the role of JNK pathway in degenerative intervertebral disc disease.Methods Eight degenerative nucleus pulposus tissues were harvested from 8 patients (6 males and 2 females) with lumbar degenerative disease,and three normal nucleus pulposus tissues were harvested from 3 patients (3 males) with lumbar fracture,intraoperatively.Differentially expressed microRNAs were screened by microRNA microarray analysis and validated by real-time qPCR.Target genes of highly expressed microRNAs were predicted by analyzing information from data bases:MicroCosm v5,TargetScan 5.1 and microRNA.org.Signal pathways associated with the target genes were analyzed,and qPCR was used to validate the screening results.Results Twenty differentially expressed microRNAs were identified.The microRNA-513a-5p and microRNA-494 were highly expressed in degenerative nucleus pulposus tissue,which was corresponding to the verification results,and the ratio was 2.222 2 and 2.948 5,respectively.Target genes of microRNA-513a-5p and microRNA-494 were MKK4 and JunD,respectively.MKK4 and JunD were both involved in JNK signaling pathway and located in upstream and downstream of this pathway,respectively.Conclusion In human degenerative nucleus pulposus cells,microRNA-513a-5p and microRNA-494 are highly expressed microRNAs,whose target genes are MKK4 and JunD,respectively.Both MKK4 and JunD are involved in JNK signaling pathway.These results indicate that JNK pathway may play important role in the pathogenesis of degenerative intervertebral disc disease.

Objective To explore the correlation between COX-2 and Ki-67 expression and microvessel density in primary gastric cancer tissue and clinicopathological parameters and to investigate their effect on postoperative gastric cancer recurrence. Methods Forty-eight postoperative recurrent gastric cancer patients were enrolled in this study, their clinicopathologic characters of primary tumors were analyzed retrospectively and compared with 48 cases without recurrence. Expression of COX-2 and Ki-67 and microvessel density ( MVD) in gastric cancer tissue were detected by immunohistochemical method. Risk factors correlated with tumor recurrence were studied by univariate and multivariate analysis. Results Expression of COX-2, Ki-67 label index (LI) and MVD were correlated with each other, and they were all correlated with depth of invasion and TNM stages in gastric cancer tissue. Patients with pelvic metastatic lymph node, cancer invasion to serosa, of Borrmann III or IV, high COX-2 and MVD expression are on high risk of recurrence (P

Objective To investigate the correlation between clinicopathologic factors and peritoneal dissemination from gastric cancer, and the impact of palliative resection on the prognosis of patients with gastric cancer complicated by peritoneal dissemination. Methods Based on our database built in 1994, the clinicopathologic data and the result of follow-up of all gastric cancer patients were analyzed retrospectively using the software of SPSS. Results One hundred and five out of 792 (13. 3% ) patients with primary gastric cancer were found complicated with peritoneal dissemination. The clinicopathologic factors in patients with peritoneal dissemination were significantly correlated with primary tumor penetrating through serosa, lymph node metastasis, primary tumor involving whole stomach, undifferentiated carcinoma, Borrmann IV and female gender (P

Objective To compare the efficacy of laparoscopic-assisted hemicolectomy with that of open hemicolectomy for right colon carcinoma and to explore the safety and effectiveness of the formor procedure. Methods The clinical data on 46 patients who had undergone laparoscopic-assisted hemicolectomy and 68 patients who had received open hemicolectomy between December 2009 and December 2013 in our department were retrospectively analyzed. Length of postoperative hospital stay, surgical duration, amount of intraoperative blood loss, number of lymph node dissection, time to postoperative anal exhaust, surgical costs, postoperative complications, and survival rate were compared between the two groups. Results There were no statistical differences between the two grounps in gender, age, body mass index, pathological typing, depth of invasion, and total number of lymph node dissection. Length of hospital stay was 6.84 days in the group of laparoscopic-assisted hemicolectomy and 11.72 days in the group of open hemicolectomy , with a statistical significance. Surgical duration and treatment costs did not differ significantly between the two groups; while amount of intraoperative blood loss (76.63 mL vs. 141.5 mL) and time to postoperative anal exhaust differed significanly. Conclusions Laparoscopic-assisted hemicolectomy is safe and effective for treatment of colon cancer , It has advantages of small trauma, rapid postoperative recovery, and a nice-looking surgical incision.
