ObjectiveTo study the effect of electromygraphic biofeedback on upper extremity function in patients with hemiplegia after stroke.Methods79 patients were randomly divided into experimental group(40 cases) and control group(39 cases).Patients in each group were given clinical treatment and regularly physical therapy, while those in experimental group were given electromygraphic biofeedback training. All patients were evaluated with electromyography amplitude and active range of motion(AROM) of wrist dorsiflexion and upper extremity Fugl-Meyer assessment pre-treatment and 3 months after stroke.ResultsAll the patients gained improvement after treating(P<0.05).Compared with the controls, patients in experimental group significantly improved their function in all measured item(P<0.01).ConclusionThe electromygraphic biofeedback can improve the arm function of hemiplegic patients.

Objective To investigate the neuroprotective effect of ginkgolide B (BN52021) o n the histopathology of brain tissue after traumatic brain injury in rats. Methods Forty-eight healthy SD rats, weighing 250 g, were evenly randomized into 4 groups: sham control group, model group, low dose BN52021 group and high dose BN52021 group. Rats in the latter 3 groups were made into fluid percussion brain injury models. After operation, the rats in the low and high dose BN52021 groups were treated with BN52021 (low dose: 1 mg/kg, ip, high dose: 5 mg/kg, ip, once daily for 7 days). On the 7th day after treatment, cerebral tissues were harvested from each group, and the histopathological changes of brain tissue were observed by Fast blue, electron microscope and immunohistochemical method. Results Compared with sham control group, model group had significantly decreased neurons (P<0. 05), increased OX-42 immunoreactive microglial cells and astrocytes (P<0. 05), and cells positive for caspase-3 (P<0. 05). Electron microscope found chromatin aggregation, nuclear fragmentation, rounder and larger mitochondria, void formation and disappeared cristae of mitochondria, endoplasmic reticulum hypertelorism, increased lysosomes, and nuclear membrane folding. Compared with model group, the low and high dose BN52021 groups had significantly decreased proportions of microglial cells and astrocytes (P<0. 05), significantly decreased caspase-3 positive cells (P<0. 05), and improved ultrastructure, with the improvement in the high dose group being more notable than that in the low dose group. Conclusion BN52021 has protective effect on the morphology of brain tissue in rats with traumatic brain injury.

Objective To investigate the infection of Chlamydia (CT) Untie urea mycoplasma (UU) and person type mycoplasma (MH) in urology outpatients clinic and sexually transmitted diseases clinic and drug resist-ance. Methods A British UNIPATH Clean View Chlamydia rapid immunoassay kits and Tianyang Zhongshan City electronic biosensor Limited production of mycoplasma culture and identification of susceptibility kit were used for the detection of secretion from 3,280 cases of non-gonococcal urethritis (GNU). Results Of 3,280 cases of GNU, only 241 cases were detected with positive CT, accounting for 7.35%, 1163 cases with simply UU positive, ac-counting for 35.46%, only 14 cases with MH positive, accounting for 0.43% ,. Overall detection rate of UU and CT was 42.77% and 11.59% respectively. 122 cases were detected with positive UU + MH, accounting for 3.72%. Female infection rate was higher than that of males (P < 0.01 ) ; UU, MH, MH + UU were more sensitive to azithremycin, Josamycin, doxycycline, roxithromycin, Minocycline. Conclusion The infection rate of urogenital mycoplasma and ehlamydia is higher and drug resistance rate is different. Azithromycin and Josamycin are the best to treat mycoplasma infection, followed by doxycycline, Pyronine Doxycycline, Minocycline.

By means of a comprehensive coverage of the numbers,distribution,makeup and efficiency of health human resources in China,a comparative study was made as to the deployment for the present stage.It reveals the following findings:sufficient human resources in general,with its growth lagging behind economic development; out-of-balance deployment; irrational makeup as shown in the inverse ratio between doctors and nurses; good efficiency of the health professionals.Based on these findings,the researchers put forward the feasible policy suggestions as to optimizing the mechanisms of the introduction,training,evaluation and incentives for these professionals.

In order to achieve real-time data acquisition and process, a signal acquisition and process system was designed based on USB2.0., in which DSP (Digital Signal Processor) acted as the core. Utilizing the powerful data processing capability of DSP, this system can extract biomedical signals from weak signals and then analyze them. At the same time, it realizes a high-speed and dependable transmission of data between DSP and PC.

Objective To evaluate the feasibility and efficacy of optical coherence tomography (OCT) in interventional diagnosis and treatment of borderline coronary artery disease. Methods Sixteen 40%-70% angiographically stenotic lesions from 15 patients were enrolled in the current study. Intravascular OCT was applied to each lesion after informed consent was obtained to evaluate stenosis percentage, size of lipid core, thickness of fibrous cap, existence of plaque rupture, and presence of thrombosis or calcification. Therapeutic strategies were made according to OCT outcomes as well as clinical symptoms and electrocardiographic changes. Stent coverage, apposition, and tissue prolapse between stent struts were determined in the patients undertaken percutaneous coronary intervention(PCI). Results Qualitative OCT images were obtained in 14 lesions. Ten lesions were greater than 50% stenosis, with large lipid core and fibrous cap thinner than 65 ?m, and plaque ruptures were noted in 2 of the lesions. PCI were performed in these 10 lesions. Two lesions underwent predilatation and significant intima tearings and dissections were detected with OCT. Repeated OCT after stent implantation showed complete coverage in all 10 lesions. Focal incomplete apposition were noted in 2 lesions. Significant tissue prolapse occurred in 3 lesions and segmental incomplete deployment of stent in 2 lesions. The remaining 4 lesions had small lipid cores, thick fibrous caps but with no plaque ruptures, thus PCI was not performed. Conclusion Intracoronary OCT is an effective tool to determine features of coronary lesions. It plays an important role in diagnosis of vulnerable lesions, strategy-making in treating borderline coronary artery disease and evaluation of immediate result of PCI.

180 U/L.CK-MB raised in only 5 cases(15.6%),and the highest was 28 U/L.Of the 218 MPP patients,only the 5 patients(2.3%) with raised CK-MB levels could be diagnosed as myocardial damage complicated with MPP.Conclusions The abnormal ECG is more important than myocardial zymogram in the diagnosis of myocardial damage complicated with MPP.Only higher level of certain myocardial zymogram without abnormal ECG can not be diagnosed as myocardial damage if lack of clinic and other objective evidences for myocardial damage.In watching out for myocardial damage,excessive examinations and treatments shall be avoided if possible.

The fast transmission and large range of emergence of infectious diseases jeopardize human health, social and economic development, which is a great threat to global public health. World Health Organization for the new features of infectious diseases on theInternational Health Regulations was revised to help member countries improve the ability to respond to public emergencies. Our government promptly revised theCommunicable Disease Prevention Act, enacted a series of laws and strategies to promote the establishment of infectious disease surveillance and response systems. Chinese medicine was included in the country infectious disease prevention and control system. After nearly 10 years of development, the prevention and treatment of Chinese medicine on emergence of infectious diseases, the clinical medicine and research capacity of respond infectious diseases has been significantly improved, and become an important part of our system of infectious disease prevention and control.
