Objective To discuss the value of video-assisted thoracoscope in the treatment of esophageal leiomyoma. Methods Clinical data of 19 patients with esophageal leiomyoma treated by video-assisted thoracoscopy from July 2000 to October 2007 were reviewed retrospectively.Under general anaesthesia with the patients at the lateral position according to the location of esophageal leiomyoma,3 incisions were made on the chest wall for insertion of the trocars.Gastroscope was applied for intraoperative auxiliary operation.Results Under a video-assisted thoracoscope,enucleation of the leiomyoma was performed on 18 of the patients,the other one,who were diagnosed with esophageal leiomyoma(3 cm ? 2 cm) was converted to thoracotomy because of the tumor was confirmed huge during the thoracoscopy.No postoperative death or severe complications occurred.Pathological examination confirmed the diagnosis of leiomyoma in all of the cases.The patients were followed up for a mean of 24.5 months(5-35 months),no recurrence was found during the period. Conclusions Video-assisted thoracoscopy can be the first choice for the treatment of esophageal leiomyoma.Open surgery should be considered if the tumor is huge.

Euphorbia kansui (EK) is a toxic herbal drug, and often used after vinegar-processing to reduce its toxicity. In present study, a 1H-NMR based metabonomic approach was used to evaluate the detoxification effect of vinegar-processed EK. The water extracts of EK and VEK were administered orally to male SD rats at doses of 9 g x kg(-1) x d(-1) for 1 week, respectively, and one more week observation was further conducted. The control group was orally given with saline. Histopathological studies of liver samples on the 8th and 15th day were conducted, and the metabolites of rat urine and liver were analysed by 1H-NMR. Histopathological studies of liver samples from EK and VEK treated rats showed no negative impacts. In metabonomic analyses of urines, changes of metabolites indicated liver damages, kidney lesions and imbalance of gut microbes in the second week. VEK-treated rats showed a quite lower toxicity compared with EK-treated ones. The present study revealed that the metabonomic approach might be helpful for the evaluation of toxicity of EK and detoxic effect of VEK.

Objective To investigate the clinical features of renal tumor patients with yon Hip-pel-Lindau (VHL) disease. Methods Clinical data of 9 renal tumor cases with VHL disease were analyzed and reviewed. The renal tumor characteristics were compared with data of 46 sporadic renal cell cancer (SRCC) cases during the same period. Results In the 9 renal tumor cases with VHL dis-ease presented, significant statistical differences were found in the aspects of bilateralness (7 vs 0), ipsilateral multicentricity(5 vs 2)and cystic growth pattern(6 vs 1) compared with SRCC (P＜0.01). During the average follow-up period of 54 months, no significant difference was found in the median survival between VHL disease patients and SRCC patients(136 vs 42 months). However, a better tendency of VHL disease over SRCC was found in survival curve study. Conclusions VHL disease should be considered when renal tumors present bilateral, multicentric or with cystic growth pattern. Management should be individualized with close watchful waiting in combination with nephron sparing surgery. Nephrectomy should be avoided when possible.

Objective To investigate the expression of c-kit and analyze its relationship with proliferating cell nuclear antigen (PCNA) in RCC subtypes and its clinical progression. Methods Expression of c-kit protein was retrospectively studied with immunohistochemistry in paraffin sections from 137 cases of clear renal cell carcinoma (CCRCC), 82 papillary renal cell carcinoma (PRCC), 51 chromophobe renal cell carcinoma (ChRCC). Results The positive rate of c-kit in ChRCC was 94.1%(48/51), it was statistically higher than that in CCRCC (16. 1%, 22/137) and PRCC (28.1 %, 23/82)(P=0. 001 ). In ChRCC, the positive expression of c-kit was related with TNM stages. The positive expression of PCNA was related with the grade in CCRCC and PRCC. But there was no relationship between PCNA expression and grade of ChRCC. It also had the relationship with the metastasis in CCRCC. Conclusions The expression of c-kit in ChRCC is higher than in other subtype of RCC, and associated with tumor local progression. That makes c-kit as a helpful marker to discriminate different subtypes of kidney cancer.

Objective To determine the length of warm ischemic (WI) tolerance in bronchial graft from non-heart-beating donors. Methods Forty-eight rats were randomly divided into 4 groups (each group having 12 rats) according to different WI durations including WI-0 min (group A), WI-30 min (group B), WI-45 min (group C) and WI-60 min (group D). In each group, the tracheae from 6 rats were respectively imbedded in greater omentum of other 6 rats, and 14 days later, the transplanted tracheae were taken from recipients to evaluate epithelial thickness and regeneration. Results Epithelial thickness and the degree of epithelial regeneration had no significant difference (P >0. 05) between the syngeneic control group and the WI-30 minutes group. All of the grafts with WI duration of 45 min were viable, but the epithelium was significantly thinner than that in the syngeneic control group (P<0. 05). However all of the grafts with WI duration of 60 min showed lower viability rate. Conclusion The time limits of tolerance to WI of tracheal grafts from NHBDs may be 45 min.

Previous studies showed that three methods for regulating and invigorating lung and kidney (lung invigorating and spleen strengthening, lung invigorating and kidney tonifying, and Qi supplementing and kidney nourishing) could regulate inflammatory signaling pathways of chronic obstructive pulmonary disease (COPD) in rats, so as to alleviate inflammation. In the present study, R-value comprehensive evaluation method was used to evaluate the comprehensive effect of three methods for regulating and invigorating lung and kidney on inflammatory signaling pathways. Rats were randomly divided into control, model, lung invigorating and spleen strengthening, lung invigorating and kidney tonifying, Qi supplementing and kidney nourishing and aminophylline groups. The COPD rat models were established by cigarette smoking combined with bacterial infection, and orally administered with drugs between the 9th and 20th week. Afterwards, efforts were made to observe the long-term effects between the drug withdrawal and the 32rd week and detect indicators in two batches in the 20th week and 32th week. Specifically, (1) Linking JAK/STAT signaling pathway: JAK2 mRNA, and protein expressions of STAT-1, STAT-3, STAT-5, JAK-2; (2) NF-kappaB signaling pathway: Smad2 mRNA and protein expressions of I-kappaB, NF-kappaB, TGF-beta1; (3) PPARgamma and antioxidant signaling pathway: SOD, PGE mRNA, PPARgamma protein. According to the results, 5 indicators in JAK/STAT pathway, 4 indicators in NF-kappaB pathway, and 3 indicators in PPARgamma pathway were significantly rectified by three methods for regulating and invigorating lung and kidney in between the 20th week and 32nd week. Between the 20th and 32nd week, the recipes for rectifying JAK/STAT pathway with intensity from high to low were recipes for lung invigorating and spleen strengthening, Qi supplementing and kidney nourishing, lung invigorating and kidney tonifying, aminophylline, particularly those for lung invigorating and spleen strengthening; The recipes for rectifying NF-kappaB pathway with intensity from high to low were recipes for lung invigorating and spleen strengthening, lung invigorating and kidney tonifying, Qi supplementing and kidney nourishing and aminophylline, particularly the first three types of drugs. The recipes for rectifying PPARgamma and antioxidant signaling pathway with intensity from high to low were recipes for lung invigorating and kidney tonifying, Qi supplementing and kidney nourishing, lung invigorating and spleen strengthening and aminophylline. Therefore, three methods for regulating and invigorating lung and kidney showed better long-term effects in regulating COPD lung inflammation signaling pathways. Specifically, recipe for lung invigorating and spleen strengthening showed a better effect in JAK/STAT and NF-kappaB pathways, while recipe for lung invigorating and kidney tonifying and Qi supplementing and kidney nourishing showed better effects in PPARgamma and antioxidant signaling pathways. In conclusion, R-value comprehensive evaluation method can evaluate the comprehensive effect of medicines and define the ranking of multiple drugs and their main targets.
