Objective To investigate the effects of health management on risk factors of cardiovascular diseases in community residents.Methods A total of 208 adults from one single community who visited our health check-up center were randomly assigned to the control group(receiving routine consultation,n =104)and health management group(receiving health management intervention,n =104).At 1-year follow-up,fasting blood glucose(FBG),lipid profiles,and blood pressure(BP)were measured and risk factors of cardiovascular were surveyed.t or x2 test was used for data analysis.Results No difference of clinical data was found between the two groups at baseline.Follow-up results indicated that absolute risk of cardiovascular diseases,number of risk factors,health satisfaction,sick leave,daily vegetables intake and physical exercise,and BP were significantly improved in the health management group.Ten-year absolute risk of cardiovascular diseases(0.8 ± 0.4 vs 1.3 ± 0.5),number of risk factors(172 vs 283),and sick leave per year(118 d vs 264 d)were significantly decreased in the health management group when compared to the control group(all P < 0.05).Furthermore,health satisfaction(83.7%(87/104)vs 52.9%(55/104)),and daily vegetables intake(520.5 g vs 348.3 g)and physical exercise(1.2 h vs 0.3h)were significantly improved in the health management group(all P < 0.05).Conclusion Health management may be effective in decreasing risk factors of cardiovascular diseases in community residents.

The initiation and operation of the tissue repair program between the broken ends after fracture is very important for fracture healing, which goes through three intertwined and gradual evolution stages: hematoma inflammatory organization stage, primitive callus formation stage and callus remodeling stage. It is completed by a variety of tissues, cells and cytokines in the bone marrow cavity. In the study of the mechanism of fracture healing, it is found that there are many signal pathways and molecules regulating bone repair, including bone formation, bone remodeling and neovascularization. At the cellular level, it regulates osteoblasts, chondrocytes, osteoclasts and endothelial cells. Hippo signaling pathway is a signal pathway that maintains the size of organs and the balance between cell proliferation and apoptosis, and also plays an important role in maintaining bone homeostasis and bone metabolism. In the process of regulating bone development and repair, it regulates the physiological activities of cells in microenvironment through protein kinase cascade reaction and transcriptional coactivator. The upstream and downstream effectors of Hippo signal pathway directly or indirectly regulate the proliferation, differentiation and apoptosis of bone metabolic cells, and the interaction with Wnt signal pathway, Notch signal pathway and other important pathways related to bone repair show that Hippo signal pathway plays an important role in the regulation of fracture healing and may become a new target to promote fracture healing. This article reviews the regulatory mechanism of Hippo signaling pathway and its regulatory role in the process of fracture healing, and looks forward to the research prospect of promoting bone healing by using it as a target.

Objective To research the visualization of congenital heart disease by three-dimensional echocardiographic(3DE) virtual endoscopy(VE) system. Methods Datasets.from 10 healthy children and 22 patients with congenital heart disease were collected (10 patients with atrial septal defects, 6 patients with ventricular septal defects and 6 patients with tetralogy of Fallot). 3DE heart models were reconstructed by virtual reality computing techniques and visualization in scientific computing techniques. The VE system was programmed under the C++ 6.0 language condition,the visualization toolkit (VTK) platform was employed to carry out the graphics and visualization utilities. The virtual eye can move along the navigation paths in the heart by manual camera movements. Results The VE can provide special information in aspects of intracardiac anatomy, The visible heart models show precisely complex anatomy structure and spatial relationships. 3DE intracardiac endoscopic imaging can thus be visualized and navigated successfully by the VE system. Conclusions 3DE VE is a new system for the visualization of congenital heart disease.

OBJECTIVE To study the distributive properties and susceptibility of yeasts to six antifungal agents. METHODS To analyze the distributive properties of 264 clinical Candida spp isolates and study the susceptibility to amphotericin B,nystatin,fluconazole,ketoconazole,miconazole and clotrimazole.The susceptibility of yeasts was tested according to the National Committee for Clinical Laboratory Standards guideline(NCCLS M27-A2). RESULTS Strains of Candida albicans were the most frequent organism isolated accounted for 62.5% of all the isolates.C.tropicalis,C.glabrata,and C.parapsilosis accounted for 20.8%,12.5%,and 1.9%,the others accounted for only 2.3%.The main infected organs were lungs,urinary tract,and digestive tract;the susceptibility tests showed strains of Candida spp to nystatin,amphotericin B,and fluconazole were more active than to the other antifungal agents.The resistance to triazole antifugal agents could be shown. CONCLUSIONS We should strengthen the diagnosis of Candida spp and strengthen the surveillance on susceptibility of clinical isolates Candida spp so as to help the doctors choose the antifungal agents reasonably.

The maximum frequency waveforms of Doppler ultrasound blood flow signals were analyzed using a multi-scale wavelet transform. The variation of maxima of wavelet transform modulus under various scales was extracted from the time-scale representation. This novel approach was applied to the analysis of Doppler signals from carotid blood flow. It was found that the shape of this variation from cases with normal cerebral vessels differed from those associated with abnormal cases. The curve was fitted by a polynomial, and its coefficients were put into a back-propagation (BP) neural network to make a classification. The clinical experiments showed that this approach got good performance and could be a new means in the clinical diagnosis of cerebral vascular disease.

Objective To explore the demographic factors and the risk of the pedicle screw insertion of the narrow pedi?cles. Methods Thoracolumbar spine thin?section CT image data of 312 adults from September 2014 to September 2015 were ana?lyzed. The pedicle width,medial and lateral cortical thickness, spongy bone thickness, spongy bone thickness/cortical thickness, e angle and screw path length of each pedicle were measured. The incidence and the distribution characteristics of the narrow pedi?cle were analyzed. Anatomic parameters and age, gender and stature were compared between the narrow pedicle group and non?narrow pedicle. The risk of the pedicle screw insertion of the narrow pedicle was assessed. Results Among the 3 081 pedicles, 74 narrow pedicles were determined as their pedicles width were less than 5 mm, and the proportion of narrow pedicle was 2.40%. Among the 312 subjects, 26 subjects were found having narrow pedicles, and the proportion of individuals with narrow pedicles in the population was 8.33% (26/312). The incidences of narrow pedicle in thoracolumbar spine were T10 0.32%, T11 0.32%, T12 0.98%, L1 7.54%, L2 2.92%. The spongy bone thickness, spongy bone thickness/cortical thickness of narrow pedicle were lower than non?narrow pedicle. However, there were no significant differences of medial and lateral cortical thickness, e angle and screw path length between the narrow pedicle and non?narrow pedicle. Difference of the mean age between the two subjects groups had no statistical significance. The percentage of female in narrow pedicle subjects group was 84.6%(22/26), which was higher than that in non?narrow pedicle subjects group (49.7%, 142/286). The mean stature of the male and female of stenosis pedicle group subjects were 163.8±1.3 cm and 152.5±4.3 cm, which were shorter than those of non?narrow subjects pedicle group (169.5±5.6 cm, 160.1±6.6 cm). The percentage of the cortical bone breakthrough by the pedicle screws of narrow pedicle group was (84.6%, 27/32), which was higher than that of non?narrow pedicle group (14.7%, 33/224). Conclusion L1 is the most common segment of thoracolumbar spine that narrow pedicle exist, which is the result of reduction of the spongy bone thickness. Narrow pedicle mostly appears in short stature female. There is high risk of cortical bone breakthrough by insertion of the posterior pedicle screws in the narrow pedicle.
