ObjectiveTo investigate the short-term effect of health education intervention on the recovery of new schizophrenia patients. Methods82 patients were randomly divided into observation group, in which patients accepted routine antipsychotic medication, general nursing and system health education intervention, and control group, in which patients accepted antipsychotic medication and general nursing. Brief psychiatric Rating Scale (BPRS) and Positive And Negative Syndrome Scale (PANSS) were used to assess the effects. ResultsThere was no difference in the score of every factor before intervention (P>0.05), but it became different after intervention (P<0.01 or P<0.05). ConclusionHealth education intervention can improve the effect on schizophrenia.

Objective:To study the change of immunological response and cell proliferation in breast tissues augmented by polyacrylamide hydrogel injection(PHI).Methods:The expression of CD68,CD25 and PCNA in 20 breast tissues with indurations,12 without indurations after breast augmentation by PHI,and 10 normal breast tissues was examined by immunohistochemistry P-V6000; analysis was also done by H-E staining.Results:Hyperplasia of fibrous tissue and infiltration of inflammatory cells and macrophages were found in the breast and adjacent tissues 3-8 years after PHI.Positive cells of CD68,CD25 and PCNA hardly existed in the normal tissues,but the breast tissues around the polyacrylamide hydrogel had many positive cells of CD68 and PCNA,especially in cases with indurations;there were significant differences between the 3 groups(P

20?g/L) after surgery in one month.The survival rate for 1,3,5yr were 100%(n=17),91.5%(n=16) and 84.7% (n=14) respectively in the therapy group,and in the control group 95.45% (n=21),72.7% (n=16),40.91%(n=9) respectively.Sur- vival rate between two groups showed significant difference (P

Objective To explore the morphological characteristics of Barrett's esophagus under confocal laser endomicroscopy (CLE).Methods A total of 112 patients with suspected Barrett's esophagus (BE) under endoscopy were enrolled in this study.The lower esophageal columnar mucosa was examined with CLE to real-time forecast the histological type and extent of intestinal metaplasia of BE,followed by mucosal biopsies and histopathological examination in inspected area.The relationship between the features under common endoscopy or CLE and histopathological diagnosis was analyzed.Results A total of 94 patients were diagnosed as BE.Island type is the most common type under common endoscopy (54.3％),and the incidence of short-segment BE was higher than that of longsegment BE (86.2 ％ vs 13.8 ％).Specialized intestinal metaplasia,cardiac and fundic epithelium can be distinguished under CLE,and the accuracy was 94.7％,89.4％ and 91.5％ respectively.The histopathological examination in targeted biopsy specimens indicated that the proportion of intestinal metaplasia was higher in long-segment BE (9/13) than that of short-segment BE (33.3 ％,x2 =4.684,P=0.039),and the proportion of intestinal metaplasia was higher in circumferential(11/17) and tongue-like BE (65.4％) than that of island type (15.7％,x2 =15.217 and 19.399 respectively,P＜0.01).There were no significant difference in the extent of intestinal metaplasia among island type,circumferential type and tongue-like type in short-segment and long-segment BE.Conclusions The histological type of BE can be accurately distinguished with CLE.The most common type of BE is island type.The incidence of intestinal metaplasia is higher in circumferential and tongue-like type.The incidence of intestinal metaplasia is higher in long-segment BE than that of short-segment BE.

Objective To observe the efficacy of combinated inhaled glucocorticosteroid and long- ?2 - agonist for asthmatic children. Methods Forty- seven children with moderate or severe persistent asthma were treated with inhalation of the fluticasone pro-pionate and salmeterol. The PEF value and the mark according the symptom of asthma before and after treatment( week and month respectively) were recorded. At the same time the days of treatment the patient with the short - ?2 - agonist in the first week and the forth week respectively were noted. The subjective feeling and accident of patients also should be paid attention. Results There was significant difference (P

Objective To assess the impact of respiratory motion on the displacement of target area and to analyze the discrimination between free breathing and active breathing control (ABC) in patients with gastric cancer treated with post-operative radiotherapy. Methods From January 2005 to November 2006, 22 patients with post-operatively confirmed gastric cancer were enrolled in this study. All diseases were T_3/ N +, staging Ⅱ - Ⅳ. Patients were CT scanned and treated by radiation with the use of ABC. Image J software was used in image processing, motion measurement and data analysis. Surgical clips were implanted as fiducial marks in the tumor bed and lymphatic drainage area. The motion range of each clip was measured in the resultant-projection image. Motions of the clips in superior-inferior (S-I), right-left (R-L) and anterior-posterior (A-P) directions were determined from fluoroscopy movies obtained in the treatment position. Results The motion ranges in S-I, R-L and A-P directions were 11.1 mam, 1.9 mm and 2.5 mm (F = 85.15, P = 0. 000) under free breathing, with 2.2 mm, 1.1 mm and 1.7 nun under ABC (F = 17.64, P = 0. 000), and the reduction of motion ranges was significant in both S-I and A-P directions (t = 4.36, P = 0. 000;t = 3.73,P = 0.000). When compared with under free-breathing, the motion ranges under ABC were kept unchanged in the same breathing phase of the same treatment fraction, while significant increased in different breathing phase in all three directions (t = - 4.36, P = 0. 000; t = - 3.52, P = 0.000; t =-3.79, P = 0. 000), with a numerical value of 3.7 mm, 1.6 mm and 2.8 mm, respectively (F = 19.46, P = 0. 000) . With ABC between different treatment fractions , the maximum displacements were 2.7 mm, 1.7 mm and 2.5 mm for the centre of the clip cluster (F =4.07,P =0. 019), and were 4.6 mm, 3.1 mm and 4.2 mm for the clips (F =5.17 ,P =0.007). The motion ranges were significant increased in all the three directions (t = - 4.09, P=0.000 ; t =-4.46, P = 0.000 ; t = - 3.45, P =0.000). Conclusions In the irradiation of post-operative gastric cancer, the maximum displacement of organ motions induced by respiration is in S-1 direction and the minimum in R-L direction under free breathing. The use of ABC can reduce the motions significantly in S-I and A-P directions, and the same changes exist in both inter-and intra-fraction treatment.

Objective To establish diagnostic standards of confocal laser endomiroscopy (CLE) in pathological classifications of gastric cancer and evaluate the diagnostic value of CLE in vivo. Methods The confocal images of 36 patients, who were diagnosed as gastric cancer with confirmation of pathology, were collected and analyzed to establish diagnostic standards of CLE for pathological classifications of gastric cancer. The sensitivity, specificity and accuracy of CLE were determined with reference to histopathologic findiugs retrospectively. Results According to changes of glandular architecture and microvessels under CLE, gastric cancers were divided into differentiated and undifferentiated type. The sensitivity, specificity and accuracy of CLE in diagnosing differentiated carcinoma were 85.7%, 92. 3% and 90. 5%, respectively, which were 85.7%, 92. 3% and 90. 5%, respectively, in undifferentiated carcinoma. Conclusion CLE is a new tool to make pathological classifications of gastric cancer during routine endoscopic examination procedure, which correlates well with histopathologic fingdings.

Objective To estimate the value of confocal laser endomicroscopy (CLE)for differential diagnosis of gastric ulcer. Methods Patients diagnosed as gastric ulcer by conventional endoscopic mode of CLE were enrolled. The eonfocal endoscopic mode of CLE was used to observe the borderline and/or the surface of the ulcers. Biopsy specimen was taken for histopathological examination and the result of CLE was compared with histopathological finding. Results A total of 12 769 CLE images were obtained from 150 sites of 43 patients. The sensitivity and specificity of CLE for phlegmonosis process were 83.54% and 85.92%, respectively, with positive predictive value of 86.84% and negative predictive value of 82.43%. Whereas the sensitivity and specificity of CLE for intraepithelial neoplasia were 53.57% and 88.52%, respectively, with positive predictive value of 51.72% and negative predictive value of 89.26%. As for diagnosis of gastric cancer, the sensitivity and specificity of CLE were 88.37% and 93.46%, respectively, with positive predictive value of 84.44 % and negative predictive value of 95.24%. The kappa values for agreement of histopathological findings and CLE for diagnosis of phlegmonosis process, intraepithelial neoplasia and gastric cancer were 0.69,0.42 and 0.81, respectively. Conclusions CLE can provide a real-time histopathological diagnosis of the gastrointestinal tract with high sensitivity, specificity, positive and negative predictive values. Targeted biopsy can be done under CLE and the detective rates of precancerous lesions and tumors will be increased.

OBJECTIVETo study the ability of bone marrow mesenchymal stem cells (BMSCs) to repair the internal environment of the testis in male azoospermia rats.

METHODSWe established azoospermia models in 22 six-week-old male SD rats by intraperitoneal injection of busulfan at 20 mg per kg body weight. We transplanted allogeneic rat BMSCs (rBMSCs) into the testicular seminiferous tubules of the model rats and, 30 days after transplantation, observed the composition and structure of the seminiferous tubular cells by HE staining and detected the expressions of CD44, CD106, and c-kit in the rBMSCs by immunohistochemistry.

RESULTSThe number of epididymal sperm was significantly reduced in the model rats as compared with the normal controls (P < 0.01). CD44 and CD106, but not c-kit, were expressed in the isolated rBMSCs. At 30 days after transplantation of rBMSCs, lots of new cells were observed in the seminiferous tubules, some expressing CD106 and some expressing the germ cell surface marker c-kit.

CONCLUSIONBMSCs can transdifferentiate into germ cells and repair the damaged seminiferous tubules of sterile rats.
