BACKGROUND:As a commonly used tissue adhesive in China, histoacryl can produce transient polymerization and rapidly solidify biological tissue, and it has good prospect in treatment of esophageal and gastric varicose bleeding. OBJECTIVE: To explore the short- and long-term clinical efficacy of endoscopic histoacryl injection combined with ligation for the treatment of esophageal and gastric varices. METHODS: Ninety patients with esophageal and gastric varices were treated by endoscopic adhesive injection and dense ligation. There were 64 males and 26 females, aged 22-75 years. At 2-4 weeks post-treatment, patients were re-checked under an endoscope. The short-term efficacy and adverse reactions, such as the hemostasis rate, varicose vein, varicose vein diameter, red color sign and portal hypertension gastropathy were observed. Al patients were folowed up for 3-39 months after varicose vein was eradicated, to monitor the middle- and long-term clinical efficacy, including varicose vein, tissue adhesive discharging and local proliferation, rebleeding, recurrence and complications. RESULTS AND CONCLUSION: (1) Short-term efficacy: The number of varicose veins significantly reduced, red color signs reduced, and portal hypertension gastropathy improved (P< 0.01), but three cases appeared early rebleeding. The adhesives began to discharge from 2 weeks to 3 months post-treatment, no case appeared esophageal stenosis, perforation, severe infection, heterotopic embolism and other injection-related complication. (2) Middle- and long-term efficacy: varicose vein recurred in nine cases and five cases developed long-term rebleeding. Experimental findings indicate that, endoscopic histoacryl injection combined with ligation is effective to treat severe esophageal varices or (and) bleeding, with high success rate and good hemostasis effect, and it also prevents long-term rebleeding and recurrence.

Objective To improve the diagnostic accuracy of ovarian endometrioma and to discriminate it from other adnexal masses by analyzing its CT manifestations. Methods The CT images of 57 patients with 77 ovarian endometriomas proved by surgery and pathology were studied retrospectively.Results The cysts ranged in diameter from 2 to 14 cm with the mean size of 6.2 cm?5.1 cm. The margins of the cyst were sharp in 39 and ill defined in 38 endometriomas. Thin and thickened walls were found respectively in 40 and 37 of 77 endometriomas. Unilocular, bilocular and multilocular forms were seen respectively in 29(37.7%), 23(29.9%) and 25(32.5%) of 77 endometriomas. Gourd and sister forms were present respectively in 15 and 8 of 23 bilocular cysts, and sister loculi, outer son loculi, inner son loculi, and mixed forms in 10, 9, 1 and 5 of 25 multilocular endometriomas. The density of the cyst fluid varied from 11～65 HU with the mean of 28.5 HU. New hemorrhage inside cyst was found in 6 cysts. Slight or intermediate enhancement of the cyst wall of endometriomas in 42, and significant enhancement in 35 were demonstrated. 54 cysts, 13 cystadenomas with 18 lesions and 4 malignant tumors with 5 lesions were diagnosed by preoperatively by CT. The accurate rate of CT characterization was 71.4%. Conclusion The certain morphologic characteristics of the ovarian endometrioma can be showed by CT in higher extent. It is critical to familiar with these characteristics to improve the diagnostic accuracy, and to avoid misdiagnosis.

Objective To improve the diagnostic accuracy by analyzing the CT manifestations of ovarian cystadenoma .Methods The CT images of 57 patients with 62 ovarian cystadenomas proved by surgery and pathology were studied retrospectively . Results Of 62 ovarian cystadenomas, 26 cases with 31 tumors were serous,another 31 cases were mucinous . Unilocular and multilocular forms were seen respectively in 19(61.3%)and 12(38.7% ) of 31 serous cystadenomas, and in 3(9.7%)and 28(90.3%) of 31 mucinous cystadenomas.22 (71.0%) tumors were benign, and 9(29.0%)were of borderline and/or malignant transformation in 31 serous cystadenomas.23 (74.2%) tumors were benign, and 8 (25.8%) were of borderline and/or malignant transformation in 31 cases of mucinous cystadenomas.Benign cystadenomas were frequently round or oval cysts with thin regular wall and septa.Borderline or malignant transformation cystadenomas demonstrated predominately thick irregular wall or septa with projections.The overall preoperative accuracy of characterization was 48.4% in serous and 77.4% in mucinous cystadenomas.Conclusion Multilocular cystadenomas have the typical CT manifestations and CT is a high valuable procedure for imaging them, whereas unilocular cystadenomas, having similar CT findings with some other benign cystic lesions, are lack of enough characteristic features for CT correct characterization.

Objective In view of the schizophrenia risk factors during the recovery,to explore a supportive intervention program suitable for the rehabilitative schizophrenic patients.Methods Totally 64 rehabilitative schizophrenic patients were divided into the experimental group and the control group with 32 cases in each group.All the patients received the same treatment with antipsychotic drugs.The patients in the control group received the routine health education.In addition,the patients in the experimental group received supportive intervention for 4 months.The patients were assessed by IBS,APGAR,GSES and SDSS before and after intervention.Results Main effect of group factor and time factor of GSES,SDSS,APGAR and IBS had statistical significances.There were significant interaction in the scores of SDSS,APGAR and IBS.Simple effect analysis demonstrated the scores of GSES,SDSS,APGAR and IBS in the experimental group were higher than those of the control group after the intervention.Except the score of GSES,there was no differences in other scales before and after the intervention of the control group.Conclusions Supportive intervention program for the rehabilitative schizophrenic patients have good practice guidance.It can improve the patients' self-efficacy,family function and social function,also can correct irrational beliefs and to help patients better adapt to society.

Objective To explore the relative importance of factors of sleep quality in predicting the anxiety and depression emotion. Methods Sleep quality and emotional condition of 112 patients with coronary heart disease were investigated with Pittsburgh sleep quality index(PSQI), self-rating anxiety scale (SAS)and self-rating depression scale (SDS). The relation between sleep quality and emotional condition was analyzed deeply by dominance regression analysis. Results After controlling the demographic vari-able of the sex,factors of the sleep quality such as sleep efficiency and function in the daytime had predict-ing effect on depression emotion;factors such as function in the daytime, sleep quality, sleep efficiency and sleep time possessed predicting effect on anxiety emotion. Conclusions According to different contribu-tion of various factors of sleep quality to anxiety and depression emotion, we should implement selective medical and nursing intervention during clinical work.

Objective To know the point prevalence rate of social anxiety disorder(SAD) in Daqing University,and explore the influence factors about growth environment.Methods Data came from a large representative sample of 1878 university students,who were selected by stratified random cluster sampling methods according to the constituent ratio of students.They finished general situation questionnaire,interaction anxiety scale (IAS),adolescent self-rating life events check list(ASLEC),Egma Minnen av Bardndosnauppforstran(EMBU) respectively.According to the score of IAS,they were divided into 3 groups of high,mid and low.And then all of the high group,the 50％ and 10％ randomly of the mid and the low group respectively accepted the face-to-face interviews with 6 trained psychiatrists referred to SCID-I/P.Results Among 1878 Daqing university students,191 of them were diagnosed as SAD,with a point prevalence rate of 8.89％.The rate of rural students was higher than that in urban students(12.3％ vs.8.5％,x2 =7.966,P=0.017),and the rate of non-only child was higher than only child (12.0％ vs.9.1％,x2 =4.055,P=0.044).There were significant differences between SAD and No-SAD on many factors of ASLEC and EMBU.Logistic regression analysis showed that study stress in ASLEC(B=0.206),father's warm (B =-0.070),father's overprotection (B =0.286),mother's punishment (B =0.159),only child or not (B =-0.685) entered into regression equation.Conclusion The point prevalence rate of SAD in Daqing university students is 8.89％ and influenced by several growth environmental factors.Only child or not,father's warm,father's overprotection,mother's punishment,study stress in ASLEC can forecast SAD occurrence.

Objective To investigate the value of ultrasound-diffuse optical tomography(US-DOT) in evaluation of the response to neoadjuvant chemotherapy (NCT) in patients with breast cancer.Methods Fifty women with breast cancer confirmed by biopsy-pathology scheduled to undergo NCT were enrolled.US-DOT was performed and the total hemoglobin concentration(HbT) prior to and at the end of NCT.According to the response to treatment in solid tumors,patients were divided into complete response(CR) group,partial response (PR) group,stable disease (SD) group and progressive disease (PD) group.The analysis of variance compared the differences of HbT before and after NCT in each group; Pearson correlation analyzed the relationship between the relative HbT variation and the tumor size changes;Mixedeffects model analyzed the relationship between HbT and tumor size.Results After NCT,CR group had 8 cases,PR group 30 cases,SD group 12 cases and no PD cases.Before and after NCT,the mean relative variations of HbT before and after NCT were-0.525 ± 0.222,-0.328 ± 0.180 and-0.173 ± 0.167 in CR,PR and SD groups,respectively.The differences of HbT before and after NCT were statistically significant in each group (P ＜0.05).There was significant difference among tumor diameter and HbT in CR group and PR group (P ＜0.001);while in the SD group,there was no difference among tumor diameter and HbT (P ＞ 0.05).The change of HbT after NCT showed positive correlation with the change in tumor size (r =0.6).Mixed-effects model also showed that HbT change was associated with tumor size.Conclusions USDOT marker HbT is closely related to tumor size of breast cancer before and after NCT and may be applied to evaluate the response of breast cancer to NCT.

AIM:To investigate the activity of NF-?B in peripheral blood mononuclear cells (PBMCs) from patients with Graves disease (GD) and the significance in immunopathogenesis of GD.METHODS:Peripheral blood was collected from 22 untreated GD,20 treated GD with tapazole more than 1 year,and 25 healthy volunteers. PBMCs were isolated from the blood by histopaque-1077 density-gradient centrifugation. The activity of NF-?B in PBMCs was analyzed using gel electrophoretic mobility shift assay (EMSA). The contents of IL-1?,IL-6 and TNF-? were tested by radioimmunoassay.RESULTS:The activity of NF-?B in PBMCs of untreated GD group was increased remarkably,compared with that in the treated group and control (P
