OBJECTIVETo observe the influence of Pilose antler polypeptide on the glycosaminoglycan and type II collagen in the articular cartilage in experimental knee osteoarthritis.

METHODSTotally 64 New Zealand white rabbits of 6 months old were randomly divided into 2 groups:normal group (n = 8) and model group (n = 56). Model group was surgically induced into osteoarthritis model by method of Hulth. After successful modeling, the rabbits of model group were further divided into 2 groups: Pilose antler polypeptide-treatment group and control group, 24 rabbits in each group. Pilose antler polypeptide-treatment group received 0.5 ml intra-articular injection of Pilose antler polypeptide dilution liquid once in per 2 days for 30 days, while control group received 0.5 ml intra-articular injection of physiological saline. On days 7, 15 and 30 after intervention, articular cartilage samples were collected respectively. The content of glycosaminoglycan in articular cartilage was observed by toluidine blue staining and the expression of type II collagen in cartilage matrix was detected by immunohistochemical staining.

RESULTSAlong with the prolonging of time, the content of glycosaminoglycan and type II collagen in cartilage matrix of the Pilose antler polypeptide-treatment group and control group decreased gradually. On days 7, 15 and 30 after intervention, integrated optical density of the type II collagen positive area in cartilage matrix of the Pilose antler polypeptide-treatment group were (312.06 +/- 14.12), (273.31 +/- 12.42) and (248.34 +/- 10.41), which had statistically significant differences. Integrated optical density of the type II collagen positive area in cartilage matrix of the control group were (253.47 +/- 15.53), (215.67 +/- 9.72) and (160.01 +/- 13.23), which had statistically significant differences. At the same period, integrated optical density of the type II collagen positive area in cartilage matrix of the Pilose antler polypeptide-treatment group was higher than that of control group, which had statistically significant difference.

CONCLUSIONPilose antler polypeptide can inhibit reduction of the glycosaminoglycan and type II collagen in cartilage matrix and delay the degeneration of articular cartilage.

OBJECTIVETo investigate the hand hygiene (HH) compliance and its influencing factors in order to improve the HH of healthcare workers (HCWs).

METHODSHH compliance of HCWs in randomly sampled departments in our hospital was observed and recorded single-blindly by specially-trained staffs using a uniform method.

RESULTSThe total compliance rate of HH of HCWs was 30.2%, which varied among different departments and posts, and working areas. It was significantly higher in ward doctors than in outpatient physicians (P < 0.01). However, the compliance was not significantly different among nurses in different departments (P > 0.05). The compliance of HH of HCWs after surgical procedures (40.4%) was significantly higher than that before procedures (19.6%) (P < 0.01).

CONCLUSIONThe compliance of HH of HCWs remains low, which is somehow affected by factors such as departments, posts, and treatment modes.

OBJECTIVETo investigate the effects of microwave radiation on thymocytes in mice at different power densities.

METHODSThe experimental animals were whole-body exposed to microwave radiation with frequency of 2,450 MHz, power density of 1, 5, 15 mW/cm(2) respectively 1 h everyday for 30 days. Then the thymus were taken out after the mice were decapitated. Thymus index, morphological characteristics of thymus were examined. The changes of thymus T-cell subgroups, cell cycle progression in thymocytes and cellular apoptosis were detected with flow cytometry (FCM).

RESULTSThe body weights of animals in 5, 15 mW/cm(2) irradiation groups [(28.10 +/- 1.46), (27.50 +/- 2.52) g] were lower than that of the control [(31.95 +/- 2.51) g] (P < 0.05). Pathological observation showed dark red piece of nucleus, some nuclei inclined to one side, slight increase in hassall body. The expressions of CD8 in 5, 15 mW/cm(2) irradiation groups (29.14% +/- 1.68%, 29.18% +/- 0.81%) were higher than that in control group (26.95% +/- 1.27%) (P < 0.05). The percentages of G(2) + M phase thymocytes in both radiation groups (12.24% +/- 1.82%, 11.19% +/- 1.36%) were lower than that in control group (14.58% +/- 0.64%) (P < 0.01). Thymocytic apoptosis rates in the three experimental groups (7.18% +/- 0.99%, 10.06% +/- 1.58%, 9.45% +/- 0.92%) were higher than that in control (4.25% +/- 1.63%) (P < 0.01), but the evident difference between 5 mW/cm(2) and 15 mW/cm(2) was not found (P > 0.05).

CONCLUSIONSub-chronic microwave exposure (2 450 MHz, 5, 15 mW/cm(2)) could induce thymocyte apoptosis, cause pathological changes in thymus, and affect cell cycle progression, thus may inhibit the immune function of the animal.

OBJECTIVEDescribe the mental health services provided at different types of general hospitals in Beijing.

METHODSDistribute the "Hospital Mental Health Services Survey" to all 508 hospitals in the 18 Beijing districts; the survey covers information for 2001 on the type of mental health services provided, the characteristics of the service providers, the number and diagnoses of first-visit mental health patients, and the prescription of psychotropic medications.

RESULTS73% (373/508) of the hospitals completed the survey, including 75% (325/436) of the general hospitals. Among the 325 general hospitals, 171 (53%) provided one or more types of mental health services; they had a total of 420 staff members who provide these services, but their educational level was relatively low and mental health training limited. 61 general hospitals had mental health outpatient departments that treated 50% (47,151/93,891) of all first-visit mental health patients seen in all hospitals (including psychiatric hospitals) in the municipality; 90% (42,578/47,151) of these first-visit patients in general hospitals were seen at 18 level-3 hospitals. Among the 44,441 first-visit patients for whom diagnostic information was available, the main diagnoses were neurosis (43%) and depression (30%). 103 of the participating general hospitals prescribed 73% of antidepressant medications prescribed at all hospitals in the municipality and 97% of all fluoxetine (Prozac and others).

CONCLUSIONSGeneral hospitals-particularly level-1 and level-2 general hospitals-need to put more emphasis on mental health services, increase training of staff who provide the services and open relevant departments. Monitoring the development of mental health services in general hospitals and increasing the quality of their mental health services will require periodic assessment of the types and range of mental health services provided and of the diagnostic accuracy and treatment standards of the staff providing these services.

To investigate a baculovirus insect cell system for expressing an interferon alpha 2b (IFNa2b)/immunoglobulin G-4 (IgG4) Fc fusion protein, which has long-acting antiviral effects. Human IFNa2b and IgG4 Fc cDNAs were generated by molecular cloning and inserted into a baculovirus shuttle vector, which was then transposed into the DH10 Bac strain to form recombinant Bacmid-IFN/Fc. The Bacmid-IFN/Fc was transfected into High five insect cells, and expression of the IFN/Fc fusion protein was detected by Western blotting and its biological activity was assessed by the cytopathic effect inhibition method. The IFNa2b and IgG4 Fc cDNA fragments were successfully amplified by RT-PCR using human peripheral lymphocytes. After cloning into the baculovirus shuttle vector, pFastBac1, and transforming into DH10 Bac competent cells, screening identified positive clones carrying the recombinant Bacmid-IFN/Fc. A Bacmid-IFN/Fc clone was successfully transfected into the High five insect cells and packaged into the baculovirus for expression of the IFN/Fc fusion protein. Western blotting revealed that the fusion protein expression was specific, and yielded a protein of 45 kD in size. The in vitro antiviral activity of the IFN/Fc fusion protein was 580 IU/mL. A novel IFN/Fc fusion protein was successfully generated using a baculovirus insect cell system, which may prove useful for providing future experimental data for development of a new long-acting interferon to treat chronic viral hepatitis.

OBJECTIVETo study the effect of Tangshenkang Granule (TG) containing serum on renal mesangial cells' (RMCs) proliferation and TGF-β1/Smad2/3 pathway in the high glucose condition.

METHODSTwelve SD rats were randomly divided into four groups, i.e., the low dose TG group, the middle dose TG group, the high dose TG group, and the blank control group, 3 in each group. After 7-day gastrogavage via portal vein blood, rats were sacrificed and their serum samples were collected. RMCs were cultured in common rat serum and TG containing serum respectively. The proliferation of mesangial cells was determined by methly thiazolyl tetrazolium (MTT) assay to determine the optimal TG containing serum concentration. Expression levels of TGF-β1 mRNA and protein were determined by real time quantitative PCR and ELISA. Smad2/3 protein expression and phosphorylation were determined by Western blot and immunofluorescence.

RESULTSTG containing serum at different doses could inhibit high glucose induced RMC cells' proliferation, TGF-β1 over-expression and Smad2/3 phosphorylation.

CONCLUSIONTG containing serum could inhibit high glucose induced RMC cells' proliferation, and its mechanism might be possibly associated with inhibiting TGF-β1/Smad2/3 signaling pathway.
