Objective To investigate the safety and feasibility of lapraroscopic Heller myotomy combined with Dor fundoplication surgery. Methods Three cases with achalasia have been treated with laproroscopic Heller-Dor surgery since February, 2005. Before surgery, patients were examined for generally esophageal barium meal and esophageal manometry. Results The operation time ranged from 110 and 120 minutes with the bleeding volumes between 40 to 50 ml, and the hospitalized time for patients post operation was 6 to 7 days. During a month after surgery, the patients showed the normal lower esophageal sphincter pressure and remnant pressure, increased the rate of relaxation,disappeared reversed peristalsis and gastroesophageal reflux, and no recurred symptoms. Conclusions In comparison to conventional surgery, Heller-Dor procedure results in smaller wound, less pain, fewer complications, faster recovery, shorter hospitalized days, and better therapeutic effectiveness. The Heller-Dor procedure is safe and feasible.

Objective To study the effect and toxicity ofgefitinib combined with selected radiotherapy in the treatment of patients with advanced non-small-cell lung cancer (NSCLC). Methods From March 2006 to February 2009,10 of 13 advanced NSCLC patients who got benefit from gefitinib were enrolled to treatment group (gefitinib concurrent selected radiotherapy) and control group (gefitinib only), with 5 cases in each group. The response was evaluated as progression free survival (PFS) and overall survival (OS).Results No patient got complete remission (CR). Ten of 13 patients got partial remission (PR) and stable disease (SD). The 1 year and 2 years survival rate was 53.8%(7/13) and 46.2%(6/13) respectively. The median PFS in treatment group and control group was 24 months and 8 months respectively(P= 0.0019). The median OS was 32 months and 10 months respectively (P= 0.0062). The main toxicities were reversible skin rash and diarrhea,and 3 patients developed asymptomatic radiation pulmonary fibrosis. Conclusions Gefitinib combining with selected radiotherapy is effective and tolerated in patients with advanced NSCLC. It may prolong PFS and OS. It may be a rational choice for the standard and individualized treatment of NSCLC.

quamous metaplasia occurred, the expression of occludin and ZO-1 in cells were similar to those in control group, which might play a role in the defense function of neovaginal mucosa.

Objective To investigate re-innervation in the neovaginal mucosa of patients underwent sigmoid colon vaginoplasty in treatment of Mayer-Rokitansky-Kistner-Hauser Syndrome (MRKHS).Methods Biopsies in the upper third of the posterior neovagina were taken in 20 patients treated by sigmoid colon vaginoplasty at 1, 2 and 3 years after surgery, respectively. Protein gene product 9. 5 ( PGP 9. 5 ),vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY) were detected by immunohistochemical method and compared with those in intact sigmoid colon mucosa. Results ( 1 ) Density of nerve fiber:abundant distribution of PGP 9. 5 nerve fibers were observed in the mucosal muscle layer, submucosa, and smooth muscle layer of the neovagina. The nerve fibers of VIP and NPY immunoreactivity were mainly distributed around blood vessels and in the smooth muscles. In the neovagina, the density of nerve fibers of PGP 9. 5 of 17 ± 6 were much more than VIP of 2. 9 ± 1.0 and NPY of 2. 5 ± 0. 8 significantly ( P ＜ 0. 05 ).( 2 ) Expression of PGP 9. 5 in neovagina: at 1 year after surgery, PGP 9. 5 positive expression of 14 ± 4 was significantly lower in the neovagina than 28 ± 7 in the intact sigmoid colon( P ＜ 0. 05 ). However, after 2 to 3 years, its expression displayed an upgrade tendency in the neovagina and was significantly higher at the 3 year postoperatively than that at the 1 years postoperatively ( 22 ± 7 vs. 14 ± 4, P ＜ 0. 05 ). The changes were much more obvious in submucosa. (3) The expression of VIP and NPY in neovagina: at 1 year after surgery, VIP and NPY positive nerve fibers were also decreased in the neovagina when compared with those in the intact sigmoid colon ( 2. 3 ± 0. 7 vs. 5.3 ± 1.4, P ＜ 0. 05; 2.5 ± 1. 1 vs. 5.5 ± 1.1, P ＜ 0. 05 ) . At 2 to 3 years after surgery, the positive VIP fiber showed initially decreased and subsequently increased tendency. The density of VIP of 3.7 ± 0. 7 in the neovagina at 3 years postoperatively was higher than 2. 3 ±0. 7 at 1 years postoperatively (P ＜ 0. 05 ). No significant up-regulation was observed in NPY-positive expression in the neovagina within 3 years after operation. Conclusions Distribution of sensory PGP 9. 5,VIP and NPY immunoreactive nerve fibers was similar to the pattern observed within the intact sigmoid colon wall. The number of nerve fibers in the neovagina decreased after surgery and then increased subsequently within 3 years after surgery.

Objective To evaluate the effect of carbon fiber couch on dose distribution of radiotherapy planning and verification pass rate.Methods Establishing the carbon fiber treatment couch model in Pinnacle8.0m Treatment Planning system (TPS),and then this model was used to correct dose calculations of oblique fields in the treatment plans of 10 cases of nasopharyngeal carcinoma,10 cases of breast cancer and 10 cases of lung cancer and evaluate the effect of carbon fiber couch on the whole dose distribution of the plans.Then these plans were measured by three-dimensional dose verification equipment Delta4 to confirm the improvement extent of Gamma pass rate after considering the carbon fiber treatment couch.Results For the majority of plans,when the carbon fiber couch was taken into consideration,the target doses was significantly reduced (4772 cGy-7266 cGy vs.4859 cGy-7347 cGy,P=0.000-0.002) and the relative deviation of D95 was 1％ to 3％.Measurement results of Delta4 showed that Gamma pass rate (3 mm/3％ criteria) increased in all plans (96.4％-98.8％ vs.93.4％-97.3％,P =0.000),some of that were up to 5 percentage when the couch model was applied.Conclusions Target doses will be overestimated if the treatment couch is ignored in TPS measurement.,However it should arouse enough attention when the disease with smaller doses corresponding gradient.

Objective To explore the short-term result and safety of laparoscopie sleeve gastrectomy and partial enterectomy for the treatment of morbid obesity.Methods Ten patients underwent laparoscopic sleeve gastrectomy,omentectomy,and partial enterectomy as a treatment option for weight reduction between December 2006 and September 2007.The procedure included 70%-75%vertical (sleeve)gastrectomy,omentectomy,and 1/3 to 2/5 enterectomy preserving proximal jejunum and most of the ileum.
