Objective To observe the therapeutic effect of low molecular weight heparin calcium (LMWHC) in treating unstable angina pectoris.Methods 78 hospitalized patients of unstable angina pectoris were randomly divided into two groups:32 as control group who were treated with routine method,and 46 as treatment group who were treated with routine method plus LMWHC.Results The clinical therapeutic effect in the treatment group was 91.3%,which compared with the control group (62.5%) was obviously of great significance (P

Objective To research the effects of tianeptine and lithium on expression of pCREB in hippocampus of chronic stress depression rats. Methods All the experimental rats were divided by random into : Group of depression,Group of tianeptine,Group of lithium and Group of control. The rats of Group of depression, Group of tianeptine and Group of lithium were applied stress for 21 days,and meanwhile Group of control had no stress. The rats of Group of tianeptine were fed with tianeptine (50 mg/kg) , Group of lithium were fed with lithium (60 mg/kg) , while another groups were fed with normal sodium of the same volume. The ethology examination was performed by using method of open-field and experiment of fluid consumption. The expression of pCREB was detected by Western-blotting method. Results After the chronic stress,the horizontal crossing numbers,the erection times,the modification times and the percentage of sacchar-consumption of the rats of Group of depression were 23.2±23.0;8. 1 ±7.2; 3.6 ±3.5 and (55.4 ±11.7)% respectively, which were less than Group of control (46.0±18.9;20.3±11.3;8.4±2.7 and (68.5 ±8.2)% ; P＜0.01). The horizontal crossing numbers(28. 1 ±23.0) ,the erection times(12. 1 ± 9.4) and the modification times(5.5 ±3.2) of Group of tianeptine are less than those of Group of control (P ＜ 0. 05), but no significant difference compared with Group of depression; the percentage of sacchar-consumption(62.7 ± 10.6) % ,Group of tianeptine was more than Group of depression (P＜ 0.05 ) , but no obvious difference with Group of control. The horizontal crossing numbers, the erection times, the modification times and the percentage of sacchar-consumption of Group of lithium were less than those of Group of control (P ＜ 0.05), more than those of Group of depression but no significant difference (P ＞ 0.05). In Westernblotting method,the level of pCREB in the hippocampus of Group of depression was less than that of Group of control (P＜ 0.01); that of Group of tianeptine was more than that of Group of depression (P ＜ 0.01) but no obvious difference with Group of control; that of Group of lithium was less than that of Group of control (P＜0. 01) and more than Group of depression (P＜0.01). Conclusion Tianeptine could reverse the reduction of expression of pCREB in hippocampus of chronic stress depression rats and lithium partly did it.

Medical psychology and psychiatry is the obligatory courses for five-year and seven-year medical students. With the rapid changes of society and continuous improvement of medical services , it is necessary to adjust and integrate the teaching content of these two courses. Teaching order of some chapters in the teaching syllabus was not helpful for students to understand the teaching content. Some teaching content was repetitive. Part of the self-study content urgently needs to teach with the development of the society and changes in disease spectrum. After the adjustment , the teaching content of the curricu-lum with strong pertinence was clear and coherent. It improved the teaching efficiency and knowledge of students;therefore, the curriculum is widely praised by the students.

Objective To summarize the clinical experience of laparoscopic cholecystectomy(LC) for acute cholecystitis.Methods Clinical records of 58 cases of acute cholecystitis treated by LC from March 1998 to May 2004 were respectively reviewed.Results Intraoperative cholangiography was conducted in 6 cases,5 of which were found to have common bile duct stones.Of the 5 cases,2 underwent LC combined with choledoscopic choledochotomy, stone removal and T tube drainage; the other 3 cases had ill defined relationship of Calot′s triangle and underwent conversion to open choledochotomy with stone removal and T tube drainage.In 52 cases were diagnosed as simple gallbladder stones, LC was successfully accomplished in 50 cases and conversion to open surgery was required in 2 cases because of serious inflammatory adhesions.In this study 1 case had jaundice after operation and 3 cases had leakage of bile,and all recovered on conservative treatment . Conclusions LC can be performed safely in the majority of cases of acute cholecystitis.

Objective To research the changes of regional gray matter volumes in first-episode, medication naive females with major depressive disorder. Methods Magnetic resonance imaging and voxel-based mor-phometry were used to compare regional gray matter volumes between 14 medication-naive female participants with a first episode of major depressive disorder ( MDD) ( age( 29. 5 ±6.8) years, number of education years(11.4 ± 2. 7) years, duration of iIIness(5.4 ±5. 2 ) months, H AMD score(27.6 ±5.5)) and 14 female healthy comparison participants (HC) (age(29.5 ±6.9)years,number of education years( 12. 2 ±3. 3)years,HAMD score(2. 1 ± 1.9)). Results Volumes of bilateral anterior cingulate cortex ( ACC) and right amygdala were significantly smaller in the MDD group than those in the HC group. Conclusion These results suggest that volume reductions in ACC and amygdala in females with MDD are present at illness onset.

ObjectiveTo explore the magnitude of the deformation of Durom cup after press-fit implantation in cadaver models and to investigate which part of the cup would deform the most.Methods Three fresh adult cadaver pelves were harvested and were cleaned of soft tissue,preserving the sacrospinous and sacrotuberous ligaments.Bilateral acetabular replacements in all cadaver pelves were performed by a senior surgeon.All acetabulums were reamed with corresponding reamers,and the direction of reaming was 40°to 45° of abduction and 15° to 20° of anteversion.Larger reamers were used sequentially until the anterior and posterior walls were firmly engaged.Six Durom cups were implanted.The deformation of each cup was detected by 3D Digital Image Correlation (3D DIC) method,and the magnitude and the parts of the deformation were recorded.ResultsThe diameters of cups were 50 mm in 2,52 mm in 2 and 54 mm in 2,respectively.All cups generated different degree of deformation,which were mostly located in the posterior-superior quadrant and the areas of the ramus of ischium.After measuring the maximum deformed areas for three times,it was found that the localized depression deformation occurred in all cups.The average deformation value was (41.73±8.86) μm (range,29.91-49.43 μm).There was no significant change in deformation value 24 hours after press-fit implantation and 7 days after removing the cups.ConclusionDurom large diameter metal acetabular component will generate deformation during the press-fit implantation.And the deformation may play an important role in more wear and more ions release.

Objective To evaluate the findings of computerized tomography (CT) imaging in patients with primary pulmonary fungal infections.Methods CT findings and clinical data of 18 cases of primary pulmonary fungal infections from 2004 to 2012 were retrospectively analyzed.The diagnoses of all patients were confirmed by pathology or serology.Results The CT of primary pulmonary fungal infections showed soft tissue density nodules in 15 out of 18 cases,and masses in 3 out of 18.By pathology or serological examination,there were 12 cases of Aspergillus infections,3 cases of cryptococcal infections and 3 cases of coccidioidomycosis.The CT findings of all of the 12 cases of Aspergillus infection showed quasi-circular shaped lesions,with lobulation and spiculation (6/12),bronchial through syndrome (3/12),the air crescent sign (6/12),or mediastinal/hilar lymphadenopathies (3/12).Six cases presenting air crescent sign were all diagnosed with primary pulmonary aspergillosis.Among 12 aspergillosis cases,6 cases underwent CT enhancement scan,among which 3 showed no enhancement and 3 showed slight enhancements.The CT findings of all eases of Cryptococcus neoformans infections were cauliflower-like shape,with lobulation,spiculation,and no focal point calcification or mediastinal/hilar lymphadenopathies.After enhancement,all of the lesions were enhanced heterogeneously.The CT findings of all the coccidioidomycosis were irregular shaped lesions with halo sign and mediastinal/hilar lymphadenopathies.All 3 cases of halo signs were diagnosed with primary coccidioidal infections.Conclusions The CT findings of primary pulmonary fungal infections have certain characteristics.Diagnosis could be made based on CT imaging together with clinical manifestations before pathological results are available.

Objective To evaluate the effectiveness of three neurological assessments in experimental autoim?mune encephalomyelitis. Methods Thirty-two female C57BL/6 mice (18-20g) were randomly divided into normal group (n=15) and immune group (n=17). Immune group were induced subcutaneously in the flank by emulsion consisted of MOG33-35 and complete Freund’s adjuvant. Mice were assessed by two investigators for 35 days after immunization in a blinded manner using Kono’s 5-point criterion, Weaver’s 15-point criterion and improved 15-point criterion. Based on H&E staining, we analyzed the accuracy, sensibility and dependency of three assessments. Results 35-day clini?cal-score plots revealed that the fluctuation of symptoms was more obvious in improved 15-point criterion compared with the other two criteria. 15-point criterion and improved 15-point criterion are more accurate than 5-point criterion in atypical-onset EAE. 15-point criterion and improved 15-point criterion could detect the neurological deficits much earli?er than 5-point criterion (P<0.001). Neurological scores assessed by improved 15-point were well correlated with the pathological findings during the peak and remission stage. Conclusion Improved 15-point criterion is better neurological score system than Kono’s 5-point criterion and Weaver’s 15-point criterion because of its accurate assessment of the neurological deficits in experimental autoimmune encephalomyelitis.

Objective To explore the relationship between human papilloma virus (HPV) infected population and disease occur‐rence in order to provide evidence and some reasonable suggestions for people understanding this disease .Methods A total of 2 508 suspected patients in our hospital from August 2012 to August 2013 were performed the HPV subtype detection by using PCR‐re‐verse dot blot(RDB) ,including 18 kinds of high risk HPV subtypes(HPV16 ,18 ,31 ,33 ,35 ,39 ,45 ,51 ,52 ,53 ,56 ,58 ,59 ,66 ,68 ,73 , 83 ,MM4) and 5 kinds of low risk HPV subtypes (HPV6 ,11 ,42 ,43 ,44) .Finally ,the patients condition was tracked through the hospital information management system and the clinical laboratory information systems .Results The HPV detection rate was 12 .26% ,in which the high risk type was mainly HPV 52 ,accounting for 12 .66% ,followed by HPV 58 ,16 .The low risk types were mainly HPV 43 ,6 ,11 ,accounting for 14 .61% ,10 .39% and 8 .44% respectively .By the follow up observation of clinical outcomes , the homotype positive phenomena were repeatedly appeared in the patients infected by HPV 52 ,16 within 2 years .At the same time ,the thinprep cytologist test(TCT) results in 157 cases of high risk HPV infection (genotype 52 ,58 ,16 ,18 ,66 ,33 ,56 ,68) were performed the tracking analysis ,indicating that high risk HPV infection was closely associated with cervical intraepithelial ne‐oplasia (CIN)Ⅰ ,CIN Ⅱ and canceration .Meanwhile ,their leucorrhea routine detection were followed up ,which manifested by mild to moderate inflammation .Conclusion High risk HPV subtype infection is closely associated with CIN Ⅰ ,CIN Ⅱ and canceration , while the leucorrhea routine shows mild ,moderate inflammation .Therefore ,only conducting the simple leucorrhea routine analysis can not really reflect the infection status ,it is necessary to look for the ways to cooperate with the superior hospital for timely detec‐ting HPV infection situation ,moreover regular follow up of people with HPV positive is the effective pathway to prevent CIN and cervical cancer .
