Objective To observe the effect of connect meridians inducing Yin from Yang on muscle-tension after cerebral infarction. Methods 82 patients with cerebral infarction in Second Hospital of Harbin from 2010 to 2014 were divided into observation group (n=41) and control group (n=41) according to hospitalization order. The observation group accepted acupuncture of connecting meridians inducing Yin from Yang, and the control group accepted the traditional acupuncture method for 2 weeks. The situation of spasticity, the motor limb function of limbs, and activities of daily living were evaluated with modified Ashworth Scale (MAS), Clinic Spasticity Index (CSI), Fugl-Meyer Assessment (FMA) and Barthel index (BI), respectively. Results Compared with the control group, the score of MAS decreased (t=2.212, P=0.030), the score of CSI decreased (t=2.514, P=0.014), the score of FMA increased (t=4.288, P<0.001), and the score of BI in-creased (t=2.970, P=0.004) in the observation group after treatment. Conclusion The acupuncture of connecting meridians inducing Yin from Yang can reduce the muscle-tension of limbs, improve the motor function and increase the activities of daily living.

AIM To establish the model of exudative pleurisy induced by alternatively activating complement and to study protection of anti inflammatory drugs on it. METHODS Purified cobra venom factor (CVF) was injected into the pleura, and then exudate volumn, total leukocyte count, protein content and histamine concentration were determined. RESULTS CVF, injected into rat pleura at dose of 0 08～2 mg?kg -1 , induced exudative inflammation in dose dependent and time dependent manner. Both diphehydramine and isoprenaline reduced significantly exudate volume, total leukocyte count, protein content and histamine concentration, while indomethacin, dexamethasone and cyclophosphamide also reduced exudate volume, total leukocyte count and protein content, although they did change the release of histamine. DLF, one of the toxic components in cobra venom, potentiated CVF induced inflammation. CONCLUSION CVF can induce significantly exudative pleurisy sensitive to anti inflammatory agents. DLF has augmentation on CVF induced inflammation.

OBJECTIVE To evaluate the antibacterial activities of cefoperazone combined with sulbactam against Gram negative bacteria,and compare with other antimicrobial agents.METHODS The antibacterial activities of 10 frequently used antibiotics against 1 670 strains of clinical isolated Gram negative bacteria were studied by using agar dilution methods according to the NCCLS 2002.RESULTS The results showed imipenem was the most active tested against Enterobacteriaceae such as Escherichia coli and Klebsiella pneumoniae,followed by cefoperazone-(sulbactam),which had similar activities as imipenem against the non-fermentative strains such as Pseudononas aeruginosa,and Acinetobacter spp,but cefoperazone-(sulbactam) had higher susceptibility to imipenem-(resistant) Stenotrophomonas maltophilia.CONCLUSIONS Cefoperazone-sulbactam has good and broad spectrum(antibacterial) activities especially against Gram negative(bacteria,) and is expected to have a bright prospect in the treatment of severe hospital infections induced by Gram negative bacteria.

OBJECTIVE To study the prevalence,fungal species,therapy and prevention of invasive fungal infections in our Affiliated Hospital.METHODS From Jan 2004 to Dec 2005,all patients with positive results for fungal culture of blood and sterile fluid were reviewed retrospectively.The in vitro activity of antifungal agents against fungal isolates was determined.RESULTS Eighty-eight positive patients were collected in this analysis based on the diagnosis of invasive fungal infection in our hospital for two years,from them the majority were diagnosed as candidal infections(n=72,81.8%),the others were Cryptococcus neoformans(n=8,9.1%),Aspergillus(n=5,5.7%) and other different fungal infections.The most common was C.albicans(n=48,66.7%),C.glabrata(n=12,16.7%),and C.tropicalis(n=8,11.1%),C.parapsilosis and C.krusei were both the same results(n=2,2.8%).CONCLUSIONS Infections caused by Candida are the most common invasive fungal ones in our hospital,and C.albicans is the most common one.Fluconazole remains effective for treament of candidal infections,especially those caused by C.albicans.

Objective:To provide a retrospective analysis of the levels of occupational external exposure of radiation workers in Hubei province from 2009 to 2018 in a way to prevent and control its risks.Methods:The external individual doses were surveyed for 50 070 radiation workers between 2009 and 2018 by the effort of the Hubei Provincial Center for Disease Control and Prevention. Under the relevant national standards, the external radiation doses to radiation workers were conducted by using TLDs.Results:The average annual collective effective dose to radiation workers in a 10 years period was 1.93 man·Sv, the median of average annual effective dose of 0.14 mSv ( P25- P75: 0.06-0.30 mSv), and the average annual effective dose of 0.40 mSv. The annual effective doses received by 46 562 workers were less than 1 mSv, accounting for 92.99% of the total monitored workers. The annual effective dose varied dependent on occupational categories, showing a year-by-year decline trend and staying at a low level after 2012. The relative high radiation doses were seen in nuclear medicine and interventional radiology in medical applications, non-destructive testing and well logging in industrial applications, and other types of radiation applications. Conclusions:The average annual effective dose decreased year in a by year manner and kept at a low level. This indicated that the radiological protection measures taken during the 10 years ensure the health of workers. The continuous monitoring result suggest that much more attention should be paid to such categories workers as nuclear medicine, interventional radiology, non-destructive testing, well logging and others through improving radiation protection measures.
