Objective To discuss peer education on the rehabilitation in schizophrenia recovery.Methods According to the order of admission,108 cases of hospitalized recovery of schizophrenia patients were divided into observation group and control group,each group in 54cases.The observation group received psychiatric conventional treatment and care at the same time add peer educations,the control group only accepted psychiatric conventional treatment and care.The observation group was given for a period of 20 weeks peer education.The nurse brief mental scale (N -BPRS),self -knowledge and treatment attitude questionnaire scale (ITAQ)were assessed in the two groups at the beginning,10 weeks,20 weeks.Results The difference of N -BPRS score between the two groups was not statistically significant (t =0.191,P =0.850).In the observation group,the scores had significant differences between 10 weeks and 20 weeks peer education (t =2.757,P =0.069;t =4.000,P =0.000).The ITAQ scores of the observation group at the beginning,20 weeks peer education were (11.22 ±3.55)points,(17.22 ±4.31)points, the difference was statistically significant (P <0.01).In control group,ITAQ scores before and after treatment were (10.84 ±5.19)points,(13.12 ±6.12)points,the difference was not statistically significant (P >0.05).Conclusion Schizophrenia convalescence patients accept peer education is helpful to rehabilitation.

Objective To establish a three-dimensional finite element model of thoracolumbar fractures treated by mono-segmental instrumentation in the fractured part for testing effect of such fixation mode on adjacent segments.Methods CT scanning data of T10-L2 were used to build a normal model at T10-L2 region,a fracture model at T12 segment as well as a mono-segment fixation or short-segment fixation model.Stress of discs and vertebral body adjacent to the fixed vertebrae were tested in axial compression,anteflexion,extention,lateroflexion,and axial rotation.Results The fracture model presented significant increase concerning stress of nucleus pulposus and annular fibrosus at T10-T11 segments and annular fibrosus at L1-L2 segments in anteflexion,extention,and lateroflexion when compared with the normal model.General raise range of the stress reached around 75％,but was dropped to 23％ after short-segment fixation and to 18％ after mono-segmental fixation.And again,stress of nucleus pulposus at L1-L2 segments was increased by 46％ or so,which was declined to 12％ after short-segment fixation and to 8％ after mono-segmental fixation.Stress at lower endplate of T10 and at upper endplate of L2 in the fracture model group were increased by 24％ and 43％ respectively when compared to the normal model,but both presented a notable drop after internal fixation.The latter was decreased to a level slightly higher than that of model group,namely 8％ more after short-segmental fixation and 4％ more after mono-segmental fixation; the former was decreased to a level even lower than that of control group,namely 2％ less after short-segmental fixation and 8％ less after mono-segmental fixation.Conclusion Mono-segmental fixation reduces adjacent disc stress in contrast to conventional short-segmental fixation and hence is an effective alternative treatment of monosegmental thoracolumbar fractures.

Objective To investigate whether nimodipine could reduce complications after microvascular decompression in patients with hemifacial spasm. Methods 220 patients with hemifacial spasm , admitted into our hospital from May 2011 to Oct. 2013 , were all treated by microvascular decompression. They were divided randomly into two groups. Patients in the treatment group were treated with nimotop 50 mg/d after the operation for the first 3 days, then was orally taken 30 mg/d for a week. Patients in the control group were treated with the same after the operation without nimodipine. The postoperative complications including hearing deficit and peripheral facial paralysis were closely observed within three months after operation. Results The total effective rate was 100% in both groups. The incidence rate of peripheral facial paralysis and hearing deficit in treatment group was significant lower than that of the control group (P < 0.05). Conclusion Nimodipine has significant effect on reducing the incidence rate of peripheral facial paralysis and hearing deficit after microvascular decompression in patients with hemifacial spasm.

ObjectiveTo discuss the diagnosis and treatment of spontaneous carotid artery dissection (SCAD).Methods Clinical diagnosis and treatment data of 9 patients with SCAD were analyzed retrospectively.ResultsVascular ultrasound showed stenoses or occlusions of carotid artery.Angiography showed “flame-shaped ” sign in totally occluded proximal section and free intimal flap in stenoses section.One patient with total occlusion of bilateral internal carotid artery and 6 patients with total occlusion of unilateral internal carotid artery were treated with antiplatelet therapy.Two patients with incomplete occlusion of the carotid were operated with stent implantation in carotid arteries,and the clinical effect of both operations was satisfactory.ConclusionAngiography remains the gold standard in diagnosing SCAD,and stent implantation is an effective treatment of this disease.

Objective:To observe the therapeutic effects of Tongyushu capsules on dysmenorrhea. Methods:With the intravenous injection of oxytocin in rats, the influence of Tongyushu capsules on rat uterine smooth muscle was observed in vivo. With the intraper-itoneal injection of oxytocin to replicate the mouse model of dysmenorrhea, the effect of Tongyushu capsules on dysmenorrhea was ob-served. Using acetic acid writhing method, the effect of relieving pain Tongyushu capsules in mice was observed. By the method of ear swelling induced by xylene in mice, the anti-inflammatory effect of Tongyushu capsules was observed. By the method of ice water bath and subcutaneous injection of adrenaline, the influence of Tongyushu capsules on the acute blood stasis model in rats was observed. Results:Compared with those of the model group, the contraction of uterine smooth muscle of the groups treated with Tongyushu cap-sules at various dosage was decreased obviously (P<0. 05), the number of body torsion reaction induced by oxytocin and acetic acid in mice was obviously decreased in 15 min (P<0. 05), the degree of ear swelling in mice treated with Tongyushu capsules was signifi-cantly reduced (P<0. 05), and the whole blood viscosity, plasma viscosity, hematokrit, erythrocyte sedimentation rate and erythro-cyte electrophoresis time were significantly decreased (P<0. 05). Conclusion:Tongyushu capsules have obvious effects of the inhibi-tion of excessive contraction of uterine smooth muscle, dysmenorrhea alleviation, anti-inflammation and relieving pain, which show good therapeutic effect on dysmenorrhea.

Objective To investigate the risk factors for prognosis of severe acute pancreatitis (SAP).Methods The clinical data of 563 patients with acute pancreatitis (AP) treated from January 2008 to December 2014 were analyzed retrospectively.There were 334 patients with mild acute pancreatitis (MAP),and 198 patients with moderately severe acute pancreatitis (MSAP),and 31 patients with severe acute pancreatitis (SAP).Risk factors associated with MAP and MSAP + SAP group,MSAP and SAP group were determined by univariate logistic regression,and multivariate analysis was used to determine the risk factors for severity of AP.Results Univariate logistic regression analysis showed that age,WBC,serum glucose,calcium,urea nitrogen arterial partial pressure of oxygen (PaO2),SIRS,pleural effusion,peripancreatic fluid collection were associated with severity of AP in MAP and MSAP + SAP patients;age,serum calcium,PaO2,SIRS,pleural effusion,peripancreatic fluid collection were associated with severity of AP in MSAP and SAP patients.Multivariate logistic regression analysis showed that age,serum calcium,PaO2 and peripancreatic fluid collection were risk factor of MSAP and SAP;age,serum calcimm and SIRS were risk factors of SAP patients for persistent organ failure and pancreatic necrosis.Conclusions For elderly AP patients,measurement of arterial partial pressure of oxygen and serum calcium,peripancreatic fluid collection can help evaluate the severity of AP and early recognition.For SAP patients,the presence of SIRS,high serum urea nitrogen,and low serum calcium and peripancreatic fluid collection raise the concerns of persistent organ failure and pancreatic necrosis.
