Objective To assess the outcomes,complications,and quality of life following endoscopic thoracic sympathectomy(ETS) of the T2~T4 ganglia for treating primary palmar hyperhidrosis(PH). Methods A total of 200 cases were followed with clinic checkups or telephone inquiries for a period of 1~28 months(mean,18.4 months). Results Of the 200 cases,8 cases were loss of follow-up and 192 cases obtained a complete and fully satisfactory alleviation of palmer and axillary hyperhidrosis.No recurrence and severe complications were found.The prime complication was compensatory hyperhidrosis(52/192,27.1%),whose incidence was slightly higher in female and severe patients and unrelated to age.Other complications included 1 case of pneumothorax and 1 case of pulmonary atelectasis. Conclusions Endoscopic thoracic sympathectomy of the T_2~T_4 ganglia for palmar hyperhidrosis is effective,safe and reliable.The procedure improves patients' quality of life and gives satisfactory outcomes.However,all patients should be informed of the common complications,particularly compensatory hyperhidrosis,before the surgery.

Objective To summarize the experience of 200 cases of endoscopic thoracic sympathectomy(ETS). Methods Clinical materials of T_2~T_4 sympathectomy under thoracoscope for treating palmar hyperhidrosis from January 2003 to April 2005 were analysed. Results [WTBZ] All the 200 cases of operation were successfully completed.Symptoms of hyperhidrosis vanished with both hands dry and warm in all the patients.Plamar temperature increased by a mean of(3.1?0.9)℃ after operation.Follow-up observations in 192 cases for 1~28 months(mean,18.4 months) found no recurrence.Compensatory hyperhidrosis was found in 52 cases(27.1%). Conclusions Endoscopic thoracic sympathectomy is a safe,effective,and micro-invasive treatment for palmar hyperhidrosis.

AIM: To investigate the transcription regulation of the promoter of human telomerase reverse transcriptase (hTERT) by transcription factors c-myc and [STBX]mad1. METHODS: The various plasmids including wild type hTERT (Tw) or mutant type hTERT (Td) which both harboring luciferase gene, the expression plasmids of c-myc and [STBX]mad1, and their control vectors were constructed. The plasmids were co-trans fected into bladder cancer cell lines T24, EJ and control cells COS-7 or fibrocytes by DOTAP liposome in various combining manner, respectively. The reporter gene luciferase activities in various groups were measured 48 h after transfection. RESULTS: The luciferase activities in T24 and EJ cells treated with Tw were much higher than that in COS-7 and fibrocytes cells treated with Tw, as well as higher than that in T24 and EJ cells treated with Td, respectively. In bladder cancer T24 and EJ cells, transcription factor c-myc and [STBX]mad1 positively and negatively regulated Tw expression in a dose-dependent manner. However, the effects of c-myc and [STBX]mad1 on Td were completely opposite to Tw. Combined with c-myc and [STBX]mad1, down-regulation of Tw expression was observed. CONCLUSION: c-myc and [STBX]mad1 regulates the transcriptional activity of hTERT promoter in bladder cancer cells, and the effects might highly depend on the conservative E-box sequence CACGTG.

Objective To study the X-ray and CT features of costal eosinophilic granuloma for a better understanding.Methods Eight patients with costal eosinophilic granuloma proved by surgery or biopsy were analyzed retrospectively.All patients had X-ray plain film, 6 patients had CT examination,including a case of enhanced CT scan.Results All 8 lesions were solitary.Six lesions were in the anterior rib and 2 in the posterior rib.On X-ray, all case showed single cavity and oval lesion with clear boundary.On CT images, 5 lesions demonstrated expansile destruction of bone with cortical bone thinning, and 3 were osteolystic destruction with soft tissue mass around.On the patient with enhanced CT scan, the lesions showed a moderate and uniform enhancement.Conclusion The X-ray and CT findings of costal eosinophilic granuloma are characteristic.

Objective To summarize the experience of perioperative management of lung volume reduction surgery(LVRS) under video-assisted thoracoscopy.Methods A total of 40 patients with severe chronic obstructive pulmonary disease(COPD) underwent LVRS under video-assisted thoracoscopy.A mini-incision thoracotomy was given in 23 of them.During the operation,the Endo-GIA was utilized to resect 20%~30% of total volume of affected lung.Results The LVRS was performed in bilateral lungs in 13 patients(under thoracoscopy only in 7 patients and with the assistance of mini-incision thoracotomy in 6 patients) and in unilateral lung in 27 patients(under thoracoscopy only in 10 patients and with the assistance of mini-incision thoracotomy in 17 patients).There were no surgery-related deaths.All the patients were discharged from the hospital 9~41 days(mean,18 days) after operation.Not only symptoms of dyspnea were obviously relieved but also the respiratory index was upgraded by 1~2 grades.The comparisons on pulmonary functions between preoperative time and 1 month after operation indicated a great improvement postoperatively,including the forced expiratory volume in 1 second(FEV_1)(48.3%?4.9% vs 68.5%?5.6% predicted;t=17.169,P=0.000),the residual volume(RV)(270.0%?23.6% vs 188.0%?19.8% predicted;t=16.835,P=0.000),and the total lung capacity(TLC)((123.0%?9.8%) vs 102.0%?8.7% predicted;t=10.135,P=0.000).Postoperative complications included air leakage in 10 patients,lung infection in 5 patients,and bronchial asthma in 3 patients,all of whom were cured after symptomatic management.A follow-up was conducted in 37 patients for 3~77 months(mean,46 months).Three patients died of lung cancer at 6,10, and 20 postoperative months,respectively.Two patients died of esophageal cancer at 3 and 8 postoperative months,respectively.And one patient died of cerebrovascular disease at 6 postoperative months.The remaining 31 patients survived. Conclusions Proper perioperative management is of great importance for a successful surgery and a rapid postoperative recovery.
