Objective To assess the influence of full-thickness continuous suture method and layer interrupted suture method in emergency abdominal operation closure.Methods Two hundred and thirtyseven patients of emergency abdominal operation were divided into full-thickness continuous suture method group (145 cases) and layer interrupted suture method group (92 cases) according to the suture method.The rate of incision liquefaction and infection,time of incision suture were compared between the 2 groups,the patients with incision liquefaction and infection were given bacterial culture.Results The time of incision suture in full-thickness continuous suture method group was significantly shorter than that in layer interrupted suture method group [(18.37 ± 7.42) min vs.(25.92 ± 5.79) min],there was statistical difference (P ＜0.01).There were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing between the 2 groups (P ＞ 0.05).In full-thickness continuous suture method group,the rate of incision liquefaction and infection in median incision was significantly lower than that in rectus abdominis incision [18.58％ (21/113) vs.31.25％ (10/32)],the rate of incision primary healing was significantly higher than that in rectus abdominis incision [81.42％ (92/113) vs.68.75％ (22/32)],there were statistical differences (P ＜ 0.05).In layer interrupted suture method group,there were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing between median incision and rectus abdominis incision [33.33％ (23/69) vs.26.09％(6/23),66.67％ (46/69) vs.73.91％ (17/23),P ＞ 0.05].The rate of incision liquefaction and infection in median incision of full-thickness continuous suture method group was significantly lower than that in median incision of layer interrupted suture method group,and the rate of incision primary healing was significantly higher than that in median incision of layer interrupted suture method group,there were statistical differences (P ＜ 0.05).There were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing in rectus abdominis incision between the 2 groups (P ＞ 0.05).The bacterial culture result in patients with incision liquefaction and infection showed positive was in 26 cases,in full-thickness continuous suture method group was in 10 cases (6.90％,10/145),in layer interrupted suture method group was in 16 cases (17.39％,16/92),there was statistical difference (P ＜0.05).The mostly bacterial of infection was Escherichia coli.Conclusions The full-thickness continuous suture in median incision can shorten operative time and reduce the rate of incision liquefaction and infection in emergency abdominal operation.Suture technique has important impact on incision healing.

To investigate the relationship between partial esophagectomy with staple anastomosis for carcinoma and gastroesophageal reflux (GER). The pressure in the esophagus and intrathoracic stomach was measured with SG-Ⅱ computer manometer in 45 patients. Twenty-four-hour esophageal pH monitoring, endoscopy and pathological examination were performed in 20 patients. Resting pressure above the esophago-gastric anastomosis was higher than that under the esophago-gastric anastomosis. Twenty-four-hour pH monitoring revealed that GER occurred. Abnormal findings were observed in 80% of patients by endoscopic and pathological examinations. The results showed that GER existed in the patients after esophagectomy and esophagogastrostomy for esophageal cancer. The occurrence of GER with stapling anastomosis were similar to that with manual anastomosis. The occurrence of GER was not related with the length of postoperative period. Sleeping in semirecumbent position was an effective method to prevent GER for postoperative patients. Twenty-four-hour pH monitoring was a reliable method for detecting GER.

Objective To investigate the effects on brain tissue p38 mitogen-activated protein kinase (MAPK) and aquaporin 4 (AQP4) and neuroprotective effect of edarvone after focal cerebral ischemia and reperfusion in mice.Methods A total of 196 healthy male Kunming mice were randomly divided into four groups:a sham operation group,an ischemia-reperfusion group,a saline control group,and an edaravone group (n =49 in each group).A middle cerebral artery occlusion (MCAO) mothod was used to induce a cerebral ischemia-reperfusion model.At 2 h after ischemia,immediately after reperfusion in the edaravone group and the saline control group,edaravone (5 mg/kg) and the same volume of saline were injected intraperitoneally in mice,then repeated once every 24 h.At 2 h after MCAO,the brain water content and infarct volume at different time points after reperfusion (12 h,24 h,48 h,and 3 d) were measured respectively.At 24 h after MCAO,the expressions of AQP4 and p38 MAPK in the brain tissue of ischemic peripheral cortex were measured by Western blotting.Results The volumes of cerebral infarction (all P ＜ 0.01) and the brain water contents (all P ＜0.05) in the edaravone group were decreased than those in the ischemia-reperfusion group and saline control group at different time points,and they were most significant at 48 h.After 24-h reperfusion,the expression levels of AQP4 (0.985 ± 0.129,1.024 ± 0.117,0.713 ± 0.231) and phospho-p38 MAPK (1.123 ± 0.142,1.214 ± 0.096,0.986 ± 0.087) in the brain tissue of ischemic peripheral cortex in the ischemia-reperfusion group,the saline control group,and the edaravone group were upregulated significantly than those in the sham operation group (AQP4:0.265 ± 0.123;phospho-p38 MAPK:0.465 ±0.023;all P ＜0.01),but edaravone group were significantly lower than the ischemia-reperfusion group and the saline control group (all P ＜ 0.05).Conclusions Edaravone can downregulate the expression level of AQP4 and effectively protect cerebral ischemia reperfusion injury in mice,Its mechanism may be associated with the inhibition of p38 MAPK pathway.

BACKGROUND: The expression of main histocompatibility antigen in cornea of rats is similar to that of human. It is verified in early experiments that penetrating corneal transplantation in rats is more repetition and reliability, and the operation difficulty is lower than that in mice.OBJECTIVE: To establish rat model of penetrating corneal transplantation and analyze the reasons of complications during model preparation and the corresponding managements and probe into the method for improving the success rate of rat model of corneal transplantation.DESIGN: Randomized controlled experiment was designed.SETTING: Department of Ophthalmology , Union Hospital, Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: The experiment was performed in Department of Ophthalmology in Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from March to May 2004. Seventysix outbred female Wistar rats of two months old were employed and randomized into experimental group and control group with 38 rats in each,without eye disease, of clean grade, body mass varied from 180 to 200 g and their right eyes were taken as acceptors. Thirty-eight SD female rats were employed and their both eyes were taken as donors. All of the animals were provided from Experimental Animal Center of Tongji Medical College of Huazhong University of Science and Technology.METHODS: Central penetrating corneal transplantation in situ was adopted and the model was established on the right eye of Wistar rat. Ten minutes before operation, tropicamide eye drops was administrated twice to amplify adequately the pupil of the right eye up to 4.0 mm. According to body mass, general anesthesia was done with abdominal injection of 3.0 mL/kg chloral hydrateand dicaine eye drops was applied twice 5 minutes before the operation with 0.1 volume fraction. Routine sterilization was done on the head of rat, the eyes kept in horizontal level and respiration kept smooth. The clip in dental-ophthalmology department was used to fix the posterior of the operated eye and make it to be semiluxated. The ring driller 3.5 mm in diameter was used to collect corneas of both eyes in SD rat as the implant tissue and place in culture dish with endothelial part upward, covered with methyl cellulose of 20 g/L mass weight concentration. The ring driller, 3.0 mm in diameter was used to collect the cornea of the right eye in Wistar rat to be the graft foreman, and the implant tissue was sutured into the graft foreman on the right eye of Wistar rat with 10-0nylon thread intermittently. Eight stitches were done in corneal transplantation in the experimental group and 6 stitches in the control group. After operation, ofloxacin eye drops was administrated and the operated eye was covered with plaster. Corneal rejection was observed and the evaluation was done in 3 items, named, turbidity, edema and neogenetic vessel. The total score of 3 items was taken as the rejection index on the day. Rejection was determined if the rejection index on the day ≥5 or corneal turbidity reached the 3nd grade. x2 and Fisher definite probability methods were used for statistical examination.plant tissue and corneal rejection.RESULTS: Of 76 Wistar rat acceptors, 5 rats were dropped out, among which, 1 rat was died accidentally after operation in the experimental group, 2 rats were died accidentally after operation in the control and 2 rats were injured cornea on the operated eyes due to fighting. But by supcomplications after corneal transplantation: In the experimental group, the number with anterior adhesion of sclera, non-round pupil; limited wound healing and non-formation of anterior chamber was lower than that in the implant tissue and corneal rejection: the survival time of corneal implant tissue was similar basically in both experimental group and the control [(8.9±2.3), (8.6±2.3) days, P ＞ 0.05]. Rejection presented in both groups in 16 days after corneal transplantation and the incidence of rejection was 100%.CONCLUSION: With stitches maintained and without intervention, the acute rejection is similar in rat corneal transplantation and human corneal transplantation. It is explained in the experiment that 8 stitches in corneal transplantation in which the rat implant tissue of 3.5 mm matches graft foreman of 3.0 mm can reduce the complications of rat corneal transplantation and becomes a satisfactory animal model of corneal transplantation.Skillful microscopic operation techniques, satisfactory operation instruments and adequate amplilfied pupil can reduce to the most extent the postoperation complications in rats.
