Conclusions　C2 gene transfection can lead SGC7901 cells to apoptosis, but the mechanism has to be further study.

To explore the application of potassium titanyl phosphate (KTP) laser delivered via bronchofiberscope in the treatment of endobronchial tuberculosis. 36 patients with a diagnosis of endobronchial tuberculosis, with age ranging from 15 to 40 y were treated with KTP laser between Dec. 2002 and July 2004 (designated as treatment group). The other 36 patients diagnosed as having endobronchial tuberculosis (aged 18 to 42 y, with a mean age of 33. 5 y) without having received KTP laser treatment were included in a control group. Our results showed that the effective rates, in terms of recovery of bronchial lumen and cleanup of caseous necrotic mass were significantly higher in the treatment group 8 weeks after the treatment (P<0.01), and the healing rates of atelectasis and obstructive infection were also significantly higher in the treatment group (P<0.05 and P<0.01), but the incidence of complication after 8 weeks was no significant difference (P >0.05). No significant changes were found in SaO2 and HR before, during and after the operation in the treatment group (P>0.05). It is concluded that KTP laser is an effective therapy for endobronchial tuberculosis.

Objective To compare the efficacy and safety of icotinib therapy alone versus icotinib combined with thoracic radiotherapy for the treatment of advanced non-small cell lung cancer (NSCLC) patients with an activating epidermal growth factor receptor (EGFR) gene mutation.Methods A total of 83 patients with advanced NSCLC harboring an activating EGFR gene mutation was enrolled in this study.All the patients were randomly divided into 2 groups.Patients in group A (n =41) received thoracic radiotherapy (prescribed at 60-66 Gy) combined with icotinib (three times per day,125 mg once).Patients in group B (n =42) were given icotinib therapy alone (three times per day,125 mg once).Treatment was continued until disease progression or unacceptable toxicity or death.The primary end points were median progression-free survival (mPFS) and 12 month-PFS rate.The secondary end points included objective response rate (ORR),disease control rate (DCR) and adverse events.Results With a median follow-up of 18.2 months,mPFS was 15.2 months (95％ CI:12.2-17.4) in group A and 13.2 months (95％ CI:10.8-14.9) in group B (x2 =4.29,P=0.036).PFS rates of 12 months for group A and group B were 70.3％ and 61.2％,respectively.The ORR were 78.0％ vs.57.1％ (x2 =5.16,P =0.028),and the DCR were 95.1％ vs.92.9％ (P＞0.05) in groups A and group B,respectively.No grade 3-4 adverse events was observed in both groups except the rashes (4 cases in each group).Besides,10 patients had grade 1-2 radiation-related pneumonitis and 15 patients suffered grade 1-2 radiation-related oesophagitis in group A.Conclusions In advanced NSCLC patients with an activating EGFR gene mutation,the combination of thoracic radiotherapy and icotinib had achieved an improvement on ORR and PFS with good tolerance.Clinical trial registration Chinese clinical trial registry,ChiCTRINR-16010262.

Objective To investigate the effect of pancreatic transplantion(PTA) using diverse operative (methods) in rats. Method Inbred SD rats were used as donor and recipient, and were randomly assigned (into) 4 groups:Normal control group( Group NC), consisted of 10 rats;diabetes group(Group DC) consisted of 10 rats;PTA with enteric drainage group(Group E-D), consisted of 22 diabetic rats;PTA using bladder reconstruction group(group B-D), consisted of 22 rats.Arterial supply of transplanted pancreas was (performed) by using end-to-side anastomosis of the donors' abdominal aorta(with splenic artery) and (recipients)′ abdominal aorta; and venous drainage was performed by using end-to-end anastomosis of the (donors)' portal vein segment(with splenic vein) and (recipients)′ left renal vein(cuff method). The fasting blood glucose, body weight, food intake, water intake and urine volume of the recipient were monitored before transplantation and on the 1st, 3rd, 7th, 14th, 30th day after operation, and also the reasons of failures were analyzed. Results The operative time of recipient in E-D group was significantly longer than that in B-D group(P

Site-directed mutagenesis method was used to introduce two desired mutations, which were confirmed by DNA sequencing, into mouse complement receptor Type II gene(MCR2). Then the constructed eukaryotic expression vectors containing wild type mouse CR2/1(wtMCR2/1), mutant type mouse CR2/1 (mtMCR2/1) and human CR2 (hCR2) cDNA were transferred into mouse SP2/0 cells by electroporation. After two-week screening by G418, the stably transfected clones were obtained. Several ways including PCR, RT-PCR, and immunohistochemistry were utilized to screen those clones with interesting genes integrated and expressed. Then Epstein-Barr virus(EBV) was used to infect these transfected cells and EBER-1 (EBV encoded RNAs) hybridization results showed that only hCR2 and mtMCR2 transfected SP2/0 cells could be infected by EBV, but positive rate of the former was much higher than the latter. This study sets groundwork for elucidating the mechanism by which EBV enters the cells and for establishing the animal model of EBV-related nasopharyngeal carcinoma (NPC).
