OBJECTIVE: To evaluate characteristics and security of artificial synthetic material for repairing incisional hernia of abdominal wall. METHODS: Articles about randomized controlled studies which were focus on repairing incisional hernia of abdominal wall were collected from CNKI from 2001 to 2009 with the retrieval words of "repairing materials for hernia,polypropylene patch, and incisional hernia ofabdominal wall". And then, those articles were summed up and analyzed. RESULTS: Among 24 tests, a total of 1 393 patients who had incisional hernia of abdominal wall, abdominal-wall defect, andinguinal hernia were included in the final analysis. Polypropylene patch and polytetrafluoroethylene patch could reconstruct integrity of abdominal wall during repairing large and huge incisional hernia, characterizing by less trauma, simple operation, rapid recovery, and low relapse rate. However, import patches were expensive. Home-made dacron materials for repairing hernia has been compared with import polypropylene patch, and the results indicated that dacron materials had light foreign body sensation and good complaisance after implantation; additionally, there was no significant difference in security and adverse reaction between dacron materials and import patches. CONCLUSION: Artificial synthetic materials characterize by great biocompatibility, strong anti-tensile strength, excellent tolerance to inflexion, optional cutting, beneficial for abdominal-wall defect at differential sizes, no comfortlessness, rapid recovery, low relapse rate, and less complication. Thus, artificial synthetic materials are extensive prospect.

BACKGROUND:Internal fixation is the main treatment of humeral shaft fractures, especial y for cases accompanied several injuries. According to the fracture reduction method and fixation methods, the commonly used repair methods include intramedul ary nail and minimal y invasive plate. How to choose a safe and effective method of internal fixation is a hot issue in the repair of humeral shaft fractures. OBJECTIVE:To explore the clinical effect of different fixations of intramedul ary nail and plate in the treatment of adult humeral shaft fracture. METHODS:A total of 252 patients with humeral shaft fracture recruited from Heze Municipal Hospital from May 2010 to May 2013 were randomly divided into two groups, with 126 cases in each group. Patients in the two groups were treated with intramedul ary nail fixation and plate fixation, respectively. The average operation time, intraoperative blood loss, hospital stays, and healing time of fracture in the two groups were recorded. Al patients were fol owed up for 1 year postoperatively, the incidence of radial nerve injury, infection and non-union was compared. The recovery of shoulder joint and elbow joint of patients was assessed with Neer method and Mayo method, respectively. RESULTS AND CONCLUSION:After treatment, the rate of primary success of internal fixation showed no significant differences between the two groups (χ2=0.399 7, P>0.05). The average operation time, intraoperative blood loss, the healing time of fracture and hospital stays in the intramedul ary nail group were significantly shorter than that in the plate group B, the difference of the results were extremely significant in two groups (t=15.442 5, 21.713 4, 8.217 6, 1.214 8, P<0.01). After 1-year fol ow-up, the incidence of radial nerve injury showed extremely significant differences between the two groups (χ2=8.262 3, P<0.01);the incidence of nonunion in the intramedul ary nail group was significantly lower than that in the plate group, with extremely significant differences (χ2=3.947 2, P<0.05). The overal incidence of complications in intramedul ary nail group was significantly lower than that in the plate group, with extremely significant difference (χ2=11.977 9, P<0.01). Besides, the Neer scores of shoulder joint and the Mayo scores of elbow joint between the two groups had no statistical y significant difference (χ2=0.235 4, 0.273 0, P>0.05). Both intramedul ary nail and plate fixations show good clinical effect in treatment of adult humeral shaft fracture, and each technique has their advantages and disadvantages, we should choose the proper technique according to the patient’s condition.

Objective To investigate the features of magnetic resonance imaging(MRI)in the brain of patients with multiple system atrophy(MSA)and compare with that in Parkinson Disease(PD).Methods Thirteen patients with MSA-C,12 patients with MSA-P,and 30 patients with Pakinson disease(PD)were retrospectively studied in terms of MRI data.Results The area of the pons in the patients with MSA-C(386.4±74.2)mm2 was significantly smaller than in those with PD(528.5±40.8)mm2,as well as the average of the pons transverse diameter([17.9±1.8]mm in the patients with MSA-C and[20.2±1.4 lnun in PD patients)(t=6.5 and 4.7,Ps<0.01).The area of the pons in MSA-P patients(474.1±88.0)mm2 and the average of the pons tranverse diameter(19.3±2.4)mm were similar to those of PD patients(Ps>0.05).The average width of middle cerebellar pedncles(MCP)in MSA-C(6.1±1.6)mm and MSA-P(6.5±1.2)mm were smaller than those in PD patients(9.1±1.0)mm(t=6.2 and 7.1,Ps<0.01),whereas there was no significant difference between MSA-C and MSA-P group(P>0.05).In the MRI findings,cerebellar atrophy was the highest sensitive,and cruciform hyperintensity and hyperintensity of MCP followed.The MBI profiles were more specific for hyperintensity of cruciform and MCP than for cerebellar atrophy in MSA-C population.For MSA-P population,MRI was relatively sensitive for hyperintensity of rim of the putamen and putamen,but less specific.Conclusion The assessment of MRI may be useful to diagnose and distinguish MSA from PD.

Objective To explore the lesion distribution pattern of poststroke pathological laughing or crying (PSPLC) by using MRI,and to discuss its pathogenesis. Methods All 24 cases selected from stroke patients who were treated in the department of neurology from May 2012 to December 2015 and had complete follow?up information after their discharge through 6 months were screened for pathological laughing and crying( PLC) . MRI characteristics of cases were analyzed retrospectively to identify lesion distribution. 28 cases with acute isolated pontine infarction who did not demonstrate PLC were enrolled as a comparison group. Lesion pattern difference between 14 cases of the pontine infarction with PLC and 28 cases of acute i?solated pontine infarction without PLC was compared. Results In these 24 cases,the highest occurrence rate of PLC was 41.67% in the second month. 15 cases had forced crying (62.5%),3 cases had forced laughing (12.5%),6 cases had pathological laughing or crying (25%). MRI studies showed lesion location in the left side were 3 cases,in the right side were 1 case,in the bilateral brain were 20 cases,in the basal ganglia were 9 cases,in the thalamus were 8 cases,in the corona radiata were 6 cases,in the semioval center were 5 cases, in the cerebral cortex were 4 cases,in the cerebellum were 4 cases and in the brain stem were 14 cases. In the cases of PLC with brain stem lesion,only 1 case was isolated pontine infarction,the other patients all combined with lesions of other parts. Compared with the pontine infarction with PLC,the isolated pontine in?farction without PLC was more likely to suffer with unilateral brain lesions(71%vs 50%),but there was no significant difference (χ2=0.844, P=0.358) . Conclusion PSFLC is not a rare complication after stroke, which is associated with multiple site of brain involvement especially pontine infarction.
