BACKGROUND: There is still recrudescent risk in the convalescence stage of the acute myocardial infarction and the living condition is relatively poor. The study proved that it has relation to that the patients haven't mastered the scientific conformable life style for the myocardial infarction recovery.OBJECTIVE: Take the rehabilitation education to help the patients set up conformable life style so as to improve the quality of life.DESIGN: The patients in the convalescence stage of the acute myocardial infarction were chosen for the control study.SETTING: Nursing Institute of Beijing Medical University and two university hospitals.PARTICIPANTS: The cases were taken from the Cardiology Departm ents of the Second and Third Affiliated Hospital of Beijing Medical University from April 1999 to November 1999. Inclusive standard: the first onset of the acute myocardial infarction and voluntary for this study. Exclusive standard: not the first onset of the acute myocardial infarction. The control group contained 35 patients hospitalized from April 1999 to June 1999 conforming to the including standard. The experimental group contained 40 patients hospitalized from August 1999 to November 1999 conforming to the including standard. After eliminating the special unmatched cases and missed follow-up cases in the experimental group, the final 30 cases were respectively involved in the both groups. There were 23 male cases and 7 female cases in the control group with the mean age of(60 ± 14), and 22 male cases and 8 female cases in the experimental group with the mean age of(62 ± 10) . There was no significant difference in the age and sex in these two groups.METHODS: The Neuman health care system pattern was taken as the theoretical frame for the rehabilitation education of the patients in the convalescent stage of the acute myocardial infarction. That is the conver genceteaching and personal illustration accompanied the rehabilitation education hand books were adopted for the rehabilitation education in the experimental group before their leaving. Then the telephone education was taken for further direction and consultation during the first three months after being discharged. The evaluation information was obtained through the follow-up after the first three months.MAIN OUTCOME MEASURES: The quality of life and dimensions in the two groups.RESULTS: Compared with the control group, the scores of the quality of life, the dimensions of the body, the psychology, the duty role and the health consciousness in the experimental group were all significantly higher(t= 11.03,3.26,3.62,2.05,15.48, P < 0. 05), while there was no significant difference in the social degree( P > 0.05) .CONCLUSION: The rehabilitation education can significantly improve the quality of life of the patients in the convalescence stage of the acute myocardial infarction.

Objective To investigate the therapeutic effect and the immune function impacts of high intensity focused ultrasound(HIFU) for the treatment of hepatocellular carcinoma.Methods Twenty-five cases with primary liver cancer and 6 cases with metastatic liver cancer were treated with HIFU.The clinical symptoms,AFP levels,color Doppler ultrasound detection,CT and changes of T-cell subsets ( CD3 +,CD4 +,CD8 +,CD4 +/CD8 + ) were recorded before and after treatment.Results After HIFU treatment,among 31 patients,the clinical remission rate was 89.7％ ( 25/29 ).AFP was decreased in 83.3％ ( 15/18 ) of the patients.Color Doppler showed reduced tumor sizes and reduced or disappeared blood supply in most of the patients.CT scan displayed that the density of the target region was decreased and necrosis of the lesions occurred.The percentage of CD3 + and CD4 + cells and the ratio of CD4 +/CD8 + were significantly increased after a period of treatment( P ＜0.05 ).The proportion of CD8 + cells was decreased significantly after a period of treatment ( P ＜ 0.05 ).Conclusion HIFU is an effective technique for the treatment of hepatocellular carcinoma.Meanwhile,it can improve human immune function to certain extend.

Objective To explore the correlation of data obtained through three dimensional reconstruction and measurement of mandibular angle related angles and bigonial breadth.Methods Sixty cases of adult female head spiral CT data were involved in this study.By the three dimensional reconstruction,mandibular angle related angles and bigonial breadth were measured.Through SPSS13.0 software their correlation was analyzed,including among mandibular angle related angles and these with bigonial breadth.Results The related data of the mandibular angle were measured on the image of three dimensional reconstruction; the mandibular angle was (124.28-±-4.12)°,the mandibular elevated angle was (25.52±2.22)°,the valgus angle of mandibular angle was (9.35±7.85)°,the mandiblular included angle was (77.32 ± 2.34)°,and the tangent angle of mandible was (105.53 ± 1.79)°.The correlation analysis of the related angles of mandibular angle and bigonial breadth showed that there was a significant correlation between the angles.Conclusions Three dimensional reconstruction and measurement of mandibular angle related angles and their correlation analysis can provide theoretical foundation and basis for the preoperative design and effect evaluation of mandibular angle plastic surgery.

Objective To investigate the effects of different wavelength (595 nm,755 nm and 1064 nm) lasers on the mRNA expression of types Ⅰ and Ⅲ procollagen in cultured fibroblasts.Methods Fibroblasts from Kunming mice were cultured in vitro.They were divided into 595 nm laser group,755 nm laser group,1064 nm laser group and no laser irradiating group.The mRNA expression of the types Ⅰ and Ⅲ procollagen was detected by RT-PCR.Results The mRNA expression level of type Ⅰ procollagen in 1064 nm group was higher than that of 755 nm group,595 nm group and control group (P＜0.05).The expression levels of 755 nm group and 595 nm group were higher than that of control group (P＜0.05).But the difference between 755 nm group and 595 nm group was not statistically significant (P＞0.05).The mRNA expression level of type Ⅲ procollagen in 1064 nm group was higher than that in 755 nm group,595 nm group and control group (P＜0.05).755 nm group had higher expression than 595 nm group and control group (P＜0.05).But the difference between 595 nm group and the control group was not statistically significant (P ＞ 0.05).Conclusions Three wavelength lasers can directly promote mRNA expression of types Ⅰ and Ⅲ procollagen in fibroblasts.595 nm laser mainly promotes mRNA expression of type Ⅰ procollagen,and 755 nm laser promotes more mRNA expression of type Ⅲ procollagen than 595 nm laser.The most mRNA expression of types Ⅰ and Ⅲ procollagen is promoted by 1064 nm laser.

Objective To evaluate the efficacy and safety of minor endoscopic sphincterotomy (EST)with endoscopic papillary large balloon dilation(EPLBD)for common bile duct stones(CBDS)in elderly patients and to study the influence of the periampullary diverticula on efficacy. Methods Data of 209 patients with CBD stones(more than 1. 0 cm)over the age of 70 were retrospectively analyzed. The pa-tients were divided into EST group(103 cases)and the EST with EPLBD group(106 cases),which was further divided into two subgroups with and without periampullary diverticula.Operation time,complete stone removal rate in the first session,mechanical lithotripsy usage rate and complications were compared between the two groups. Results Compared with EST group,the EST with EPLBD group had shorter operation time [(25. 65±8. 76)min VS(35±6. 67)min,P= 0. 000],a higher success rate of the complete stone removal in the first session( 90. 57% VS 83. 50%,P = 0. 030),lower rate of mechanical lithotripsy( 8. 50% VS 55. 34%,P= 0. 000),but with a higher incidence of hyperamylemia(18/ 106 VS 7/ 103,P = 0. 044).The o-verall stone removal rates showed no difference(96. 23% VS 95. 14%,P= 0. 700).In the EPLBD group,di-verticulum had no effects on the results and complications of ERCP( P> 0. 05). Conclusion EST with EPLBD is a safe and effective method for CBDS in elderly patients. Periampullary diverticula does not affect the therapeutic effects of this method.

OBJECTIVETo explore the clinical significance of vasohibin-1 expression in colorectal cancer tissues and its correlation with vascular endothelial growth factor A(VEGF-A) and microvessel density (MVD).

METHODSTumor tissues and paired adjacent normal tissue (distance to cancer >5 cm) from 60 colorectal cancer patients undergoing resection in the Second Hospital of Tianjin Medical University from June 2013 to November 2013 were included in this study. The protein expressions of vasohibin-1, VEGF-A and MVD were detected by immunohistochemical staining. The mRNA expressions of vasohibin-1 and VEGF-A were detected by RT-PCR. The protein expressions of vasohibin-1 and VEGF-A were observed by Western blot. Correlation among parameters was examined.

RESULTSVasohibin-1 expression was mainly localized in the cytoplasm of tumor cells and endothelial cells. VEGF-A expression was mainly localized in the cytoplasm and membrane of tumor cells. The expressions of vasohibin-1, VEGF-A and MVD in colorectal tumor tissues were significantly higher than those in corresponding adjacent tissues [43.3% (26/60) vs. 16.7% (10/60), 51.7%(31/60) vs. 18.3% (11/60), (39.67 ± 16.80)/mm² vs. (17.85 ± 6.43)/mm², all P<0.05]. Higher vasohibin-1 expression was significantly associated with TNM stage and metastasis (P<0.05). Vasohibin-1 expression was positively correlated with VEGF-A and MVD (r=0.378, 0.628, all P<0.05). Vasohibin-1 and VEGF-A mRNA expressions and protein expressions in colorectal cancer tissues were significantly higher than those in corresponding adjacent tissues (all P<0.05).

CONCLUSIONVasohibin-1 expression in colorectal cancer tissues is significantly higher as compared to corresponding adjacent tissues. Vasohibin-1 expression is positively correlated to VEGF-A and MVD, and associated to TNM stage and metastasis. Positive vasohibin-1 expression indicates a poor prognosis of patients with colorectal cancer.

OBJECTIVETo study the efficacy of community management model of bronchial asthma in children.

METHODThrough community outreach and clinic, 120 cases of children with asthma were enrolled from the 11 000 children aged 0 to 14 in Zhanlanlu area, and a community management model of asthma was established according to the Global Initiative for Asthma requirements combined with the actual situation of the community, both physicians and patients participated in case identification, file creation, and long-term standardized management. Through repeated medical education, the telephone hotline and interactive network of asthma among physicians, children and parents, a physician-patient relationship was established. The data of standardized medication, scheduled re-visit to the hospital, frequency of asthma attacks, antibiotic use, medical expenses, the loss of parents work hours etc. before and after the implementation of community management model were analyzed and compared.

RESULTAfter implementation of community management model, the use of systemic corticosteroids (19.4%), oral medication (31.6%) was significantly lower than those before implementation (68.3% and 90.0%) (χ(2) = 51.9, 41.1, P < 0.01), use of inhaled corticosteroids (76.5%) and oral leukotriene receptor antagonist (79.6%) was significantly higher compared with control and before management level (10.0%), χ(2) = 106.0, P < 0.01. The days of attacks of asthma (4.6 ± 2.3), the use of antibiotics (16.2 ± 6.1), (5.7 ± 2.9) and the cost of treatment significantly decreased. In 16 cases (13.3%) two-way referral was applied. In this study, the dropout rate was 18.3%, by telephone and network supervision of lost cases, re-education, made some children return to management, eventually the dropout rate was 9.2%.

CONCLUSIONEnrollment of children with bronchial asthma into community management model made the children adhere to the management regularly and a standardized management was achieved.

Objective:To investigate the expression and clinical significance of thymidine kinase 1 (TK1), carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 19-9, CA15-3 and CA72-4 in colorectal tumors.Methods:Enzyme-linked immunosorbent assay (ELISA) and electrochemiluminescence immuno assay (ECLIA) were used to determine the serum TK1 levels and serum CEA, CA19-9, CA15-3, CA72-4 levels in 124 patients with colorectal cancer, 52 patients with colorectal precancerous lesions, 154 patients with benign colorectal lesions, and 106 health subjects. The relationship between serum TK1 and its clinicopathological characteristics in patients with colorectal cancer were analyzed. The diagnostic efficacy of TK1, CEA, CA19-9, CA15-3 and CA72-4 alone and combined detection for colorectal cancer was investigated.Results:The serum expression level of TK1 in patients with colorectal cancer was related to tumor stage, degree of differentiation, lymph node metastasis, distant metastasis and age (all P<0.05), but not related to the patient's gender ( P>0.05). The serum TK1 level decreased sequentially in colorectal cancer patients, precancerous lesions patients, benign lesions patients and healthy subjects. Colorectal cancer patients with high TK1 expression have a shorter survival time. The sensitivity, specificity and accuracy of the combined detection of TK1, CEA, CA19-9, CA15-3 and CA72-4 were 93.5%, 93.0%, and 93.1%, respectively. Conclusions:Serum TK1 is expected to become an independent marker for the diagnosis and prognosis of colorectal cancer. The combined detection of TK1, CEA, CA19-9, CA15-3 and CA72-4 has clinical significance in the diagnosis of colorectal cancer.

The incidence of colorectal cancer is high threatening human health. About 60％～70％cases of CRC are derived from colorectal polyps, which can be treated by endoscopic electrotomy to prevent the possibility of canceration. Therefore, in the prevention and treatment of CRC, the role of screening is of great significance. CRC screening methods include the most commonly used fecal occult blood test ( FOBT ) and the more sensitive fecal immunochemical test (FIT), cost-effective fiber sigmoidoscopy and colonoscopy, CT colonoscopy (CTC), and fecal DNA testing and immature CRC hematology screening. In this paper, the CRC screening technologies were reviewed, including the principles, characteristics and the latest research progress to provide a theoretical basis for the application and development of CRC screening technology.
