AIM: To explore the effects of Compound Yi-Zhi (YZC) on learning and memory capacity and free radical metabolism in D-galactose induced mice dementia model. METHODS: The mice dementia model was induced by a daily D-galactose 0.15 g?kg -1 sc for 45 d and after 5 d D-galactose injection, the mice were treated with three doses of YZC once a day for 40 d. In order to find out the influence of YZC on the models learning and memory capability and free radical metabolism system, Y-maze test was introduced for the former and superoxide dismutase (SOD) and malondialdehyde (MDA) tests for the latter. RESULTS: Compared with the D-galactose model group, three doses of YZC administration ( 0.108, 0.217, 0.433 g?kg -1) were all shown to significantly reduced the times of learning/memory in Y-maze test from 31.35? 8.97/ 17.12? 5.57 to 19.67? 8.07/ 11.27? 6.65, to 14.00? 6.84/ 8.29? 5.95, and to 11.41? 5.99/ 6.24? 4.97, respectively. For SOD, the administrations of 0.108 and 0.433 g?kg -1 YZC could increase the activity of SOD from 17.69? 3.14 to 26.94? 4.46, and to 21.33? 3.63 nU?mg -1 pro. While for MDA, all the three doses of YZC could decrease the level of MDA from 4.08? 0.88 to 2.82? 0.75, to 2.10? 0.42, and to 2.35? 0.39 nmol?mg -1 pro in the mice brain tissue, respectively. CONCLUSION: YZC can improve the D-galactose induced learning and memory dysfunction, and the action may be related to the improvement of antioxidase activity in the model mice brains.

Objective To evaluate the efficacy of intravenous methylprednisolone for prevention of tracheal intubation-related laryngopharyngeal complications.Methods Three hundred ASA Ⅰ or Ⅱ patients,aged 20-50 yr,weighing 50-80 kg,undergoing elective surgeries,requiring tracheal intubation under general anesthesia,were included and randomized into 5 groups (n =60 each).Methylprednisolone 40 and 80 mg were injected intravenously at 30 min before induction of anesthesia in groups Ⅰ and Ⅱ,respectively,while the equal volume of normal saline was given instead in group Ⅲ.Methylprednisolone 40 and 80 mg were injected intravenously at 30 min before extubation in groups Ⅳ and Ⅴ,respectively.The sore throat,hoarseness and cough were recorded within 24 h after extubation and the severity was evaluated at 1 and 24 h after extubation.Results There was no significant difference in the incidence and severity of sore throat,hoarseness and cough between the five groups (P ＞ 0.05).Conclusion Intravenous methylprednisolone can not effectively prevent tracheal intubation-related laryngopharyngeal complications in patients.

BACKGROUND: Three-dimensional printing to prepare a digital model can improve the accuracy of orbital fracture repair, and has a good clinical prospect.OBJECTIVE: To evaluate the effect of individualized titanium mesh based on the digital model in the reconstruction of orbital fracture.METHODS: Twelve cases of orbital fracture were admitted at the Hospital of Stomatology, Southwest Medical University from January 2014 to October 2015. CT scanning in axial, coronal, sagittal planes and three-dimensional reconstruction were performed routinely in all cases preoperatively. Digital model was designed by 3D printing technology according to the CT data. Individualized titanium mesh was shaped based on the digital model and used to repair orbital fracture. The accuracy of the reconstructed orbit was assessed based on the postoperative CT scan.RESULTS AND CONCLUSION: Postoperative CT scans showed that the implanted individualized titanium meshes were capable of accurately reconstructing the fractured orbit in all the 12 patients, and there was no infection, and titanium mesh loosening, prolapse, and rejection. With healthy eyes as controls, 11 cases of eyeball retraction were corrected completely, and only 1 case was still under correction. Diplopia symptoms disappeared in the 8 of 9 cases, and relieved in the 1 of 9 cases. Seven cases of eye movement limitation recovered postoperatively. To conclude, the individualized titanium mesh has great accuracy to repair orbital fractures in patients without serious complications,which has achieved good clinical outcomes in the orbital reconstruction.

Objective To investigate the preventing and curative value of endoscopic injectim sclerotherapy underlying endoscopic variceal ligations in the treatment of the patients suffering form esophageal varix recurrence.Methods The endoscopic injection sclerotherapy was performed to the patients whose esophageal varix varnished or nearly varnished after the endoscopic variceal ligation.Results There were sinificant differences (P ＜ 0.05 ) between the group of the endoscopic variceal ligation combining more dose laurornacrogol and the group of the single endoscopic variceal ligation at the recurrence rate of bleeding.No severe complications were observed during the treatments.Conclusion The endoscopic injection clerotherapy of more amount doses lauromacrogol after the endoscopic variceal ligation can signiticantly reduce residual esophageal varix after the endoscopic variceal ligation and dday esophageal varix recurrrence.

Objective To summarize our experience in the prevention and treatment of accessory hepatic duct injury during operation on biliary tract.Methods The clinical data of 26 cases with accessory hepatic duct were retrospectively reviewed.Results Of 26 cases,the accessory hepatic duct were type I in 38.5%(10/26),and no complications including bile leakage,biliary infection and obstructive jaundice developed after division and ligation of the accessory hepatic duct;26.9%(7/26) were type II,among which,the accessory hepatic duct were injured in 3 cases,but no case developecl complications after relevant treatment;23.0%(6/26) were type III,among which,injury of accessory bile duct occurred in 2 cases.Of them,1 case developed bile leakage and was cured by reoperation.7.7%(2/26) were type IV and 3.9%(1/26) was type V.The cases of type IV and V were not damaged.Conclusions To prevent injury of accessory hepatic duct,pre-and intra-operation identification of the condition is very important,and especially by intraoperative cholangiography.Different types of accessory hepatic duct injury should be treated by different approaches. Accessory hepatic duct of type I might be cut and ligated.Type II accessory bile duct which(enters) the cystic duct and should be protected,but,if damaged,different methods of treatment are used,(depending) on the caliber of accessory hepatic duct.Type III and IV also should be protected,but,when damaged,the accessory hepatic duct should be repaired or performed an internal draining.

OBJECTIVEThe aim of this study was to investigate the value of free anterolateral thigh myocutaneous flap (ALTMF) and computed tomography angiography (CTA) for the reconstruction of mouth-floor defects after the resection of middle-late stage carcinoma of the mouth floor.

METHODSSixteen cases of middle-late stage carcinomas of the mouth floor underwent radical resection, and mouth-floor and tongue defects were reconstructed with ALTMF. CTA was applied to plan the lateral circumflex femoral artery (LCFA) and its perforating vessel, which was verified during the operation.

RESULTSThe position of the perforating vessel in the operation was fully consistent with that designed by the preoperative CTA. All 16 flaps completely survived. The appearance and function of all cases were both satisfactory. All donor sites were primarily closed and healed without functional morbidity. During the follow-up period of 6-36 months, 15 cases survived with acceptable aesthetic and functional results in mouth floor and tongue reconstruction, except for 1 case (T4N2M0) that died of metastasis carcinoma 10 months after operation.

CONCLUSIONCTA can accurately locate the LCFA and artery perforator. Preoperative perforator planning using CTA in ALTMF transplantation is a reliable and useful method thatresults in safe operation with optimal outcome. The ALTMF is an ideal choice for the reconstruction of soft tissue defects after the resection of middle-late staie carcinoma of the mouth floor

Pi-dan is a signifi cant conception,which comes from Inner Canon of Huangdi.From the vivid description of Pi-dan in Inner Canon of Huangdi,we consider that the formation and process of Pi-dan is equivalent to metabolic syndrome.They are have the same etiological factor:obesity,the same pathogenesis:abdominal fullness and interior heat,and they can result in diabetes,hypertension,hyperlipidemia,fat liver,gout and a series of severity vascular complication.The theory of Pi-dan exactly points out that obesity the original cause of metabolic syndrome,and suggests that early prevention and treatment for obesity is an important method to prevention metabolic syndrome and its complications.The main pathogenesis of Pi-dan is abdominal fullness and interior heat,and the main therapeutic methods are Xiaogaojiangzhuo,Kaiyuqingre,and Huoxuetongluo.
