ObjectiveInvestigate the shape of plug mesh and patch after plug-mesh hernia repair and discuss the necessity of improving the operative procedures. MethodsUse B ultrasound to investigate the shape of plug-mesh and patch after mesh plug hernia repair and review the patients medical record,evaluate how operative procedures affect the shape of patch and the results. ResultsIn 4 of the 16 cases,the distant end of patches overlapped the pubic margin,in the remaining 12cases the distant end of patches didn't reach the pubic margin. When changing the cut-in direction of B ultrasound probe,a wide and dense shadow was discovered in 8 cases whose patches didn't reach the pubic margin. Between the pubic margin and dense shadow there was a space showing low dense shadow. These photocopies showed that the patches had folded up or crimped. In 11 of 12 cases,the patches didn't fix on pubic margin or cut shorter during operation. Conclusion It is suggested to fix the distant end of patch on the aponeurosis tissue of pubic in the procedure of mesh plug hernia repair,and combine the plug-mesh repair with Lichtenstein repair.

Objective: The purpose of our experiment is to use new type esophageal prosthesis, which is pulmonary tissue with vascular pedicle, to repair the partial esophageal defect. Methods: Twelve adult mongrel dogs were used for the study. Middle lobar bronchus of right lung was ligated and incised, so the pulmonary tissue with vascular pedicle was made. A 4 cm long and 1/2～2/3 circled esophageal wall, and full-thickness defect was created. The defect was patched by pulmonary tissue with vascular pedicle. Results: Seven dogs were put to death at planned times after the reconstructive operation. One dog is still alive without any problems for more than 12 months. One dog survived 38 days and then died of chronic empyema. The other three dogs died of anastomotic leak at 5～7 days after operation. The living dogs could be fed orally at seventh day after operation. Epithelization was found in the luminal surface of the defect. Conclusion: It was feasible that the partial esophageal defect was replaced by pulmonary tissue with vascular pedicle.

BACKGROUND: Esophageal replacement or reconstruction should be performed after esophageal resection. There are still no suitable substitutes for esophagus if the conventional esophageal substitutes cannot be used.OBJECTIVE : To investigate the feasibility of applying a pulmonary tissue with vascular pedicle to repair the intrathoracic esophageal defect.DESIGN: A prospective animal investigation.SETTING: Department of Thoracic Surgery, Second Hospital Affiliated to China Medical University.MATERIALS: This trial was carried out in the laboratory of Department of Thoracic Surgery, Second Hospital Affiliated to China Medical University during January 2003 to June 2004. Fourteen adult mongrel dogs of either gender, with body mass of 12 to 18 kg, were provided by Animal Room, Second Hospital Affiliated to China Medical University (License No.SYXK (Liao) 2003-0019).METHODS: Of 14 anesthetized dogs, the middle lobe of right lung was dissected and its right middle lobar bronchus was ligated without damaging pulmonary and bronchial vessels in order to make pulmonary flap. A part of full-layer intrathoracic esophageal wall was resected, which was 4 cm long and 1/2 to 2/3 circled esophageal wall. The defect was patched by pulmonary tissue with vascular pedicle which was inosculated with esophageal cross section. On the 3rd day after operation, intravenous transfusion was performed to maintain nutrition. Qn the 7th day after operation, the dogs were given oral liquid soft food gradually 2 weeks after the operation. The access to the food and the survival of dogs were observed. Every 2 dogs were sacrificed respectively at the 2nd, 4th, 6th, 8th and 10th postoperative weeks. To observe the healing of esophageal defect, light microscope, transmission electron microscope, esophagography and endoscope were used in this study.MArN OUTCOME MEASURES: ①Survival situation and access to food of dogs after operation. ② The healing of esophageal defect of dogs.RESULTS: Three of fourteen dogs died within one week after operation. Eleven dogs survived. ① The survival and access to food of experimental dogs after operation: One dog was alive without problems for more than 170 weeks. The living dogs could be fed orally on the 7th day after operation. ② The healing at esophageal defect of experimental dogs:At the 2nd week after operation, the esophageal defect was covered with collagen layer and inflammatory exudation. A little epithelization was observered at free edge of the anastomosis, which was 1 to 2 layers of stratified squamous epithelium cells. At the 4th to 6th weeks after operation, the internal surface of the defect was covered with 3 to 5 layers of stratified epithelium cells. At the 8th to 10th weeks after operation, the luminal surface of the defect was covered with 6 to 8 layers of stratified epithelium cells. The pathological changs of pulmonary flap mainly included pulmonary alveoli atelectasis and pulmonary fibrosis, and some inflammatory cells without infective focus were observed. In the transmission electron microscope examination, newborn stratified squamous epithelium cells were. found on the surface of pulmonary tissue flap at esophageal defect.CONCLUSION: It is feasible to repair the partial irregular intrathoracic esophageal defect with the autologous pulmonary flap in dogs.

Objective To explore the effects of Jin's Three-needle Acupuncture combined with occupational therapy on function of upper limbs for stroke patients with hemiplegia. Methods 90 patients with stroke were randomly divided into control group (n=30), observation group (n=30) and experiment group (n=30). The control group received routine rehabilitation, the observation group received occupational therapy in addition, and the experiment group received Jin's Three-needle Acupuncture and occupational therapy in addition. They were assessed with Fugl-Meyer Assessment (FMA) of upper limbs and Barthel index (BI) before and 4 weeks after treatment. Results The scores of FMA and BI improved in all the groups after treatment (P<0.001). The difference of scores of FMA and BI before and after treatment were more in the experiment group than in the observation group (P<0.001), observation group than the control group (P<0.001). Conclusion Jin's Three-needle Acupuncture combined with occupational therapy can further improve the motor function of upper limbs and activities of daily living for stroke patients with hemiplegia.

Objective:To report and analyze a rare family of sponduloepiphyseal dysplasia congenital(SEDC) in order to supply more resources for genetic bone disease. Methods:Investigation and analysis was performed on a four generation's family of SEDC.Clinic characteristics including X-ray image and chromosome analysis were evaluated.Results:Nine persons suffered from SEDC in this four(generation's) family.The patients presented with same clinical characteristics.The main bone damages affected vertebrae,articulatio coxae,caput femoris and neck. Conclusion:The mode of inheritance of SEDC may be autosomal dominant inheritance.Gene defect during embryonic period may interfere the growth of osteoepiphysis.Further molecular pathologic studies were needed to find the evidence of genetic prognostication of SEDC.

Objective:To evaluate the intestinal function in rats with exertional heat stroke (EHS) and explore the protective role of Ruifuping pectin (RFP) against heat related intestinal mucosal injury.Methods:One hundred and twenty healthy special pathogen free (SPF) male Sprague-Dawley (SD) rats were randomly divided into normothermic control group, EHS model group, hyperthermic plus drinking water group (H 2O+EHS group) and hyperthermic plus pectin group (RFP+EHS group) with 30 rats in each group. The rats in the H 2O+EHS group and RFP+EHS group were given water 20 mL/kg or RFP 20 mL/kg orally for 5 days during adaptive training period. After 1 week, the temperature control range was adjusted to (37±1)℃ using the temperature control treadmill, and the rat model of EHS was reproduced by one-time high temperature exhaustive exercise. No rehydration intervention was given during the training adaptation period in the EHS model group. The rats in the normothermic control group were maintained to room temperature (25±2)℃ and humidity (55±5)% without other treatment. Behavior tests including withdraw response, righting, and muscle strength were performed immediately after onset of EHS. Blood of inferior vena cava was collected, and the serum inflammatory cytokines [tumor necrosis factor-α (TNF-α) and interleukins (IL-6, IL-1β, IL-10)] and activity of diamine oxidase (DAO) were detected by enzyme linked immunosorbent assay (ELISA). The intestinal mucosa was collected, after hematoxylin-eosin (HE) staining, and Chiu score was performed to assess EHS induced pathological changes under light microscope. Results:The rats in the EHS model group had behavioral, inflammatory and pathological changes, such as delayed withdraw response and righting, decreased forelimb pulling, increased inflammatory index, and obvious intestinal mucosal injury, which indicated that the reproduction of the EHS model was successful. There was no significant difference in above parameters between the H 2O+EHS group and the EHS model group except that the inflammatory index in the RFP+EHS group was improved. Compared with the EHS model group, the withdraw reflex to pain and righting after RFP pretreatment in the RFP+EHS group were significantly improved (righting score: 1.4±0.2 vs. 0.3±0.2, withdraw reflex to pain score: 1.0±0.1 vs. 0.2±0.1, both P < 0.05), the muscle strength was significantly increased (N: 13.0±0.5 vs. 8.2±0.6, P < 0.01). The levels of pro-inflammatory factors in the RFP+EHS group were significantly lower than those in the EHS model group [TNF-α (ng/L): 67.5±9.2 vs. 194.3±13.7, IL-6 (ng/L): 360.0±54.1 vs. 981.2±84.4, IL-1β (ng/L): 33.7±9.0 vs. 88.7±6.1, all P < 0.01], while the level of anti-inflammatory factor IL-10 was higher than that in the EHS model group (ng/L: 208.7±10.5 vs. 103.7±7.0, P < 0.01). The degree of intestinal mucosal injury in the RFP+EHS group was less severe than that in the EHS model group, and the Chiu score and DAO were significantly lower than those in the EHS model group [Chiu score: 1.5±0.2 vs. 3.8±0.0, DAO (U/L): 83.7±6.7 vs. 128.7±10.5, both P < 0.05]. Conclusions:High temperature training can damage the intestinal barrier function, and induce endotoxemia and systemic inflammatory response syndrome (SIRS) in rats. Oral prophylactic RFP can protect the intestinal barrier function, alleviate SIRS, and promote the recovery of basic nerve reflex and muscle strength after the occurrence of EHS in rats.
