Objective To review the experience of surgical management for caustic esophageal stricture and discuss the surgical techniques of transverse colon interposition for esophageal replacement. Methods 106 patients with caustic esophageal stricture were treated surgically. 32 patients underwent colon interposition with colonphargageal anastomosis and others received colon interposition with a cerrical anastomosis. The ascending branch of the left artery of the transverse colon was preserved as the supporting vessel of the interpositioned colon. Results There was no postoperative death. The leakage of cervical anastomosis was observed in 12 patients, anastomosis stenosis in 8 patients, and tracheotomy was performed in 3 patients. All patients were perfectly recovered by the treatment. Conclusion Transverse colon interposition for esophageal reconstruction is an optimal approach in the treatment of caustic esophageal stricture.

Objective To evaluate the value of video-assisted thoracic surgery(VATS)for penetrating thoracoabdominal injuries.Methods Under general anaesthesia and double-lumen tracheal intubation,VATS was carried out to examine patients with chest injuries.Those who had mild injuries received VATS combined with mini-incision surgery.Electrocoagulation or suturing was employed to control intraoperative bleeding,and then blood clots were removed.Injured diaphragm muscles were repaired,and organs with hemorrhage or ruptures were sutured or resected.The seriously injured cases underwent open surgery and intra-abdominal exploration instead.Results A total of 18 patients received the operations.Among them,15 patients underwent VATS combined with mini-incision surgery(repair of the diaphragm was performed on 15,controlling intercostal arterial bleeding on 8,repair of the lung on 2,wedge resection of the lung on 2,and coagulated hemothorax removal on 2),the other 3 were converted to open surgery for repairing the diaphragm(3),heart(1),or esophagus(1),or lobectomy(2).Abdominal surgery via the thorax were performed on 13 cases,including repair of the liver in 1,lienectomy in 1,gastrorrhaphy in 1,repair of diaphragmatic hernia in 3,and intra-abdominal exploration in 7.Five patients received open surgery(pancreatic neoplasty in 1,repair of the liver in 1,lienectomy in 1,gastrorrhaphy in 2,and repair of the caul and mesenterium in 3).One patient who had multi-organ penetrating injuries died of hemorrhagic shock,circulatory failure,and DIC after open thoracic and abdominal surgeries.The mean operation time in this series was(125?44)minutes(ranged from 45 to 220),and the mean blood loss was(1089?582)ml(500 to 10 000 ml).Twenty-four hours after the operation,the mean volume of chest drainage was(234?75)ml(100 to 350 ml)in the first 24 hours after the operation.The chest drainage tube was withdrawn 2.5(2 to 5)days postoperation.The patients expelled gas in 1 to 4 days(mean,2 days).Totally,12 patients were followed up for 3 to 12 months(mean,6 months),during which none of them had trauma-related complications.Conclusion VATS combined with mini-incision surgery is safe and effective for patients with thoracoabdominal injuries,if the cases were carefully selected.

An evaluation scale of medical services quality was developed on the basis of "patients' experience". The questionnaires were developed by, among others, searching relevant literature, collecting well-established assessment scales, measuring patients' experience and satisfaction, brain-storming, literature analysis. Delphi method was adopted for expert consultation. Scale items were screened and revised. The key indexes were converted. Field surveys were conducted for testing the reliability and validity of the scale. Our modified evaluation scale for measuring medical services quality based on "patients' experience" included 6 dimensions (tangibility, reliability, responsiveness, assurance, empathy and continuity), and 50 items. The novel scale based on "patients' experience" may better serve the purpose of assessing medical services quality.

This paper is aimed to establish the method of fingerprint analysis of chemical constituents by reversed-phase ultra-performance liquid chromatography (UPLC) for the quality control of the roots and rhizomes of Panax ginseng (Ginseng Radix et Rhizoma). The method was performed on a ACQUITY UPLC BEH C18 (50 mm x 2.1 mm ID, 1.7 microm) with a mixed mobile phase of water and acetonitrile in a gradient mode. The flow rate was 0.3 mL x min(-1) and the wavelength of measurement was 203 nm. Eleven batches of the Ginseng Radix et Rhizoma were determined. The UPLC chromatographic fingerprints of chemical constituents were established from the eleven batches of the Ginseng Radix et Rhizoma and showed fifteen characteristic common peaks, among which fifteen peaks were recognized and nine compounds (ginsenosides Rg1, Re, Rf, Rg2, Rb1, Rc, Rb2, Rb3 and Rd) were determined by comparison with chromatographic behaviors and UV spectra of the authentic compounds. The eleven batches of samples were classified as two clusters by hierarchical clustering analysis (HCA) and principle component analysis (PCA), and six samples were confirmed to establish the mutual model. The quality was assessed by similarity evaluation system for chromatographic fingerprint of TCM (2004B Version). The convenient and high specific method can be used to identify and evaluate the quality of the Ginseng Radix et Rhizoma.
