Rheumatic heart disease is still highly prevalent in .developing countries where the incidence of coronaryartery disease （CAD） is also arising. Consequently the occurrence of coexistent CAD and mitral stenosis （MS） dominantly caused by rheumatic fever is more frequent in these countries. Comorbidities such as pulmonary and renal dysfunction occur frequently in these aging populations. Off-pump surgery is widely applied in patients with concomitant CAD and severe comorbidities due to lower incidence of postoperative morbidity. Closed mitral commissurotomy （CMC） is a well established treatment for patients with mitral stenosis. We report here a case of moderate stenosis combined with seriously diffuse 3-vessel CAD and severe chronic obstructive pulmonary disease （COPD） in an elder male treated with off-pump coronary artery bypass （OPCAB） plus CMC.

IM To study the anticancer mechanism of yangwei Kangliu (YWKL) granules from the viewpoint of red blood cell (RBC) immunity and the relationship between the red blood cell immunity and T lymphocyte immunity.METHODS We treated advanced gastric carcinoma by combination of YWKL granules and chemotherapy (n=50). Before treatment and after one course treatment, blood samples from vein were obtained, the rosette rate of c3b receptor (RBCC3bRR), tumor and red cell (RRTR) and RBC immune complex (RBCICR) were measured by counting the rosette formed by sensitivated yeast or tumor cell or unsentivated yeast adhering blood cell under microscopy. The T lymphocyte subset was observed by the method of APAAP. Chemotherapy alone was used as controls (n=20). In addition, the dynamic changes of RBCC3bRR, RRTR and RBCICR of mice with tumor after treated by YWKL granules (n=30) were observed. The chemotherapy (n=30) and water (n=30) were used as controls.RESULT Clinical therapeutic effect of combination of YWKL granules and chemotherapy (the treatment group) was markedly superior to that of chemotherapy alone (the control group) (P<001). In the treatment group, the rosette rate of c3b receptor (RBCC3bRR) and the rosette rate of tumor and red cell (RRTR) were significantly increased (P<001) after treatment, the rate of RBC immune complex (RBCICR) was markedly decreased (P<001), and the ratio of CD4 to CD8 was obviously elevated (P<001). CD8 was much lower (P<001), and the ratio of CD4 to CD8 was much higher (P<001), than the control group. The RRTR rate was positively correlated with the ratio of CD4 to CD8. Experiment in mice showed on the ninth day of bearing cancer, the tumor weight in the YWKL granules alone group was much lighter than that of chemotherapy alone group or water alone group respectively, the RBC immune function of YWKL granules alone group was higher than the other two groups, and on the thirteenth day, there wer

AIM: To investigate hepatitis B virus(HBV) prevalence in the general population in ***: A total of 148931 individuals were investigated by multistage random sampling in Eastern China. Data were collected on demographics and hepatitis B vaccination history, and serum was tested for hepatitis B surface antigen(HBs Ag) by ELISA. RESULTS: A total of 11469 participants(7.70%, 95%CI: 7.57%-7.84%) were positive for HBs Ag. HBs Ag prevalence was 0.77% among children < 5 years old but increased progressively from adolescents(1.40%-2.55%) to adults(5.69%-11.22%). A decrease in HBs Ag prevalence was strongly associated with vaccination and familial history of HBV among both children and adult groups. Meanwhile, HBs Ag risk in adults was associated with invasive testing and sharing needles. The HBV immunization rate among participants aged < 20 years was 93.30%(95%CI: 93.01%-93.58%). Significant difference in HBs Ag prevalence appeared between vaccinated and unvaccinated participants(3.59% vs 10.22%). CONCLUSION: Although the national goal of HBs Ag prevalence < 1% among children < 5 years old has been reached, immunization programs should be maintained to prevent resurgence.

In Iran,the prevalence of hepatitis C virus(HCV) infection is relatively low according to the populationbased epidemiological studies. However,the epidemiology of HCV is changing and the rate of HCV infection is increasing due to the growth in the number of injecting drug users in the society. In addition,a shift has occurred in the distribution pattern of HCV genotypes among HCV-infected patients in Iran. Genotype 1a is the most prevalent genotype in Iran,but in recent years,an increase in the frequency of 3a and a decrease in 1a and 1b have been reported. These variations in the epidemiology of HCV reflect differences in the routes of transmission,status of public health,lifestyles,and risk factors in different groups and geographic regions of Iran. Health policy makers should consider these differences to establish better strategies for control and prevention of HCV infection. Therefore,this review was conducted to present a clear view regarding the current epidemiology of HCV infection in Iran.

In this paper, a fuzzy neural model is proposed for face recognition. Each rule in the proposed fuzzy neural model is used to estimate one cluster of pattern distribution in a form, which is different from the classical possibility density function. Through self-adaptive learning and fuzzy inference, a confidence value will be assigned to a given pattern to denote the possibility of this patterns belongingness to some certain class/subject. The architecture of the whole system takes structure of one-class-in-one-network (OCON), which has many advantages such as easy convergence, suitable for distribution application, quick retrieving, and incremental training. Novel methods are used to determine the number of fuzzy rules and initialize fuzzy subsets. The proposed approach has characteristics of quick learning/recognition speed, high recognition accuracy and robustness. The proposed approach can even recognize very low-resolution face images (e.g., 7x6) well that human cannot when the number of subjects is not very large. Experiments on ORL demonstrate the effectiveness of the proposed approach and an average error rate of 3.95% is obtained.

The traditional strategy of 3D model reconstruction mainly concentrates on orthographic projections or engineering drawings. But there are some shortcomings. Such as, only few kinds of solids can be reconstructed, the high complexity of time and less information about the 3D model. The research is extended and process card is treated as part of the 3D reconstruction. A set of process data is a superset of 2D engineering drawings set. The set comprises process drawings and process steps, and shows a sequencing and asymptotic course that a part is made from roughcast blank to final product. According to these characteristics, the object to be reconstructed is translated from the complicated engineering drawings into a series of much simpler process drawings. With the plentiful process information added for reconstruction, the disturbances such as irrelevant graph, symbol and label, etc. can be avoided. And more, the form change of both neighbor process drawings is so little that the engineering drawings interpretation has no difficulty; in addition, the abnormal solution and multi-solution can be avoided during reconstruction, and the problems of being applicable to more objects is solved ultimately. Therefore, the utility method for 3D reconstruction model will be possible. On the other hand, the feature information in process cards is provided for reconstruction model. Focusing on process cards, the feasibility and requirements of Working Procedure Model reconstruction is analyzed, and the method to apply and implement the Natural Language Understanding into the 3D reconstruction is studied. The method of asymptotic approximation product was proposed, by which a 3D process model can be constructed automatically and intelligently. The process model not only includes the information about parts characters, but also can deliver the information of design, process and engineering to the downstream applications.
