Objective To investigate the situation and demands of the nursing services for both urban and rural elderly people with chronic diseases in China,so as to provide basis of establishing the new elderly care mode. Methods 1902 urban and rural elderly with chronic diseases in almost 29 provinces had been enrolled by the convenience and stratified sampling method to complete the investigation. Results The utilization of relevant nursing care and the demand of psychological counseling and hospice care in cities and towns were higher than those of villages.The demand of common chronic diseases in towns were all higher than that in cities and villages.The demand of pain management in cities wee lower than that in towns and villages.73.3％ of elderly in the survey will choose community to subsequent recovery after discharge.The physical,psychological health and economic status might be the pivotal factors. Conclusions At present,endowment in community becomes an inevitable trend in China.Meanwhile,there are still lots of problems in our community health care services,so it remind relevant staffs that some measures should be taken to change such situations.

Objective To observe the effect of stageⅢdiabetic nephropathy(DN)treated by Qizhi Jiangtang capsule and explore its potential mechanism. Methods According to digital table method,the patients who conformed to the diagnostic criteria of stageⅢDN were randomly divided into two groups:an experiment group and a control group. All the patients in the two groups took elution treatment for 2 weeks,and then were treated with western basic therapy. The patients in the experiment group were administered orally with Qizhi Jiangtang capsule(2.5 g once, 3 times a day),while those in the control group treated with valsartan 80 mg,once a day. Urine microalbumin(mALB), mALB/urine creatinine(UCr),β2-microglobulin(β2-MG),α1-microglobulin(α1-MG)were observed in the two groups,endothelin-1(ET-1),nitric oxide(NO),thromboxane B2(TXB2),6-keto prostaglandin F1α(6-keto-PGF1α) were also determined. Serum creatinine(SCr),blood urea nitrogen(BUN),serum cystatin-C(Cys-C),retinol-binding protein(RBP),β2-MG were detected in the blood biochemistry automatic analyzer. These laboratory markers were inspected before treatment and at the 4th,8th and 12th week after treatment. Results Ninety-six patients in the experiment group and 95 patients in the control group were effectively included in the end. Before treatment,there were no statistic significant differences in urine mALB,mALB/UCr,β2-MG,α1-MG and blood ET-1,NO,TXB2, 6-keto-PGF1α between two groups(all P>0.05). Along with the prolongation of treatment,urine mALB,mALB/UCr,β2-MG,α1-MG and ET-1,TXB2 were significantly reduced,while NO,6-keto-PGF1α were significantly raised in the two groups after treatment,and the above changes in the experimental group were more obvious. There were statistic significant differences of mALB,mALB/UCr,β2-MG,α1-MG and TXB2,6-keto-PGF1αbetween two groups at the 12th week after treatment〔mALB(mg/L):36.6±9.2 vs. 78.6±16.5,mALB/UCr(mg/mmol):3.90±1.97 vs. 9.70±2.90,β2-MG(mg/L):0.25±0.10 vs. 0.40±0.12,α1-MG(mg/L):8.40±2.26 vs. 12.50±3.21,TXB2 (ng/L):75.8±18.7 vs. 94.7±21.7,6-keto-PGF1α(ng/L):73.4±15.2 vs. 65.2±11.5,P<0.05 or P<0.01〕. But there were no statistic significant differences of ET-1 and NO between experimental group and control group at the same time-points〔ET-1(ng/L):57.6±6.9 vs. 59.1±6.2,NO(μmol/L):68.9±11.6 vs. 65.4±10.7,both P>0.05〕. In each of the two groups,the comparisons of the levels of SCr,BUN before and after treatment,there was no statistical significant difference at any time point;the same comparisons between the two groups,there was also no statistic significant difference before treatment and at each of the same time-point after treatment(all P>0.05). The levels of Cys-C,RBP andβ2-MG of the control group after treatment had the tendency of decreasing,but no statistic significant differences were found(all P>0.05). The levels of Cys-C,RBP,β2-MG of the experimental group at the 12th week after treatment were significantly lower than those before treatment〔Cys-C(mg/L):0.72±0.07 vs. 0.89±0.12,RBP (mg/L):53.0±14.2 vs. 66.1±16.5,β2-MG(mg/L):1.86±0.71 vs. 2.79±0.82,all P<0.05〕. Conclusions Qizhi Jiangtang capsule can significantly reduce the levels of urine mALB and mALB/UCr of patients with stageⅢDN and stabilize their renal functions;its therapeutic effect is better then that of valsartan. Its mechanisms are related to the reduction of ET-1,elevation of NO,maintenance of dynamic equilibrium of thromboxane A2/prostacycline(TXA2/PGI2) and protection of vascular endothelial cells.

The anti-hepatitis B virus (HBV) effects and its mechanisms of the ethanol extracts of Hypericum perforatum L. (EHP) in vitro were explored. HepG2 2.2.15 cells, a stable HBV-producing cell line, were cultured as the model system to observe the anti-HBV effect. The viral antigens of cellular secretion, HBsAg and HBeAg, were determined by enzyme linked immunosorbent assay (ELISA). The quantity of HBV-DNA released in the supernatant was assayed by real-time PCR. In order to understand the mechanisms of the suppression of HBV replication, all HBV promoters (Cp, Xp, S1p, S2p and Fp) with luciferase reporter gene were transfected into HepG2 cells respectively. Then the activities of viral promoters were examined by luciferase reporter assay. It was found EHP effectively suppressed the secretion of HBsAg and HBeAg from HepG2 2.2.15 cells in a dose-dependent manner, as well as the extracellular HBV DNA. And EHP could selectively inhibit the activity of HBV promoter Fp. Our data suggest that EHP exerts anti-HBV effects via inhibition of HBV transcription, which helps to elucidate the mechanism underlying the potential therapeutic value of EHP.

Objective To explore the incidence and imageological features of patients with the hippocampal sclerosis-associated medial temporal lobe epilepsy. Methods Seventy-eight patients with the medial temporal lobe epi?lepsy were recruited from our hospital during February 2012 to December 2013. Magnetic resonance imaging (MRI) and resonance spectroscopy (MRS) analysis were conducted in patients with with the hippocampal sclerosis-associated medial temporal lobe epilepsy, patients with epilepsy without the medial temporal lobe diseases and healthy controls. Results The incidence of hippocampal sclerosis was 58.97%among patients with medial temporal lobe epilepsy which were significantly higher compared with either healthy control group or patients with epilepsy without the medial tempo?ral lobe diseases. The average hippocampal volume of the medial temporal lobe epilepsy group(2305.68±814.61 mm3、2456.71±743. 60 mm3)was significantly smaller compared with either healthy controls or patients with epilepsy without the medial temporal lobe diseases. MRI revealed increased T2WI signal and hippocampal atrophy in 74.55%of patients with hippocampal sclerosis-associated medial temporal lobe epilepsy. Sclerosis was detected on the left side (52.17%) and bilateral hippocampus (19.57%). MRS showed that NAA/(Cr ± Cho) significantly reduced (0.58± 0.19) in the hip?pocampal sclerosis. Conclusions Hippocampal sclerosis may be the main imaging features of the medial temporal lobe epilepsy which are characterized by the hippocampal atrophy and high T2WI signal.

Allogeneic hematopoietic stem cell transplantation is an effective method for treating various hematological diseases. Membranous nephropathy is the second leading cause of novo glomerular disease after transplantation. Protocadherin FAT1 is a target antigen for diagnosing membranous nephropathy, primarily related to hematopoietic stem cell transplantation. Here we report a rare case of membranous nephropathy after hematopoietic stem cell transplantation. The target antigen of membranous nephropathy was confirmed to be FAT1 by pathology combined with mass spectrometry analysis. The nephrotic syndrome achieved partial remission after corticosteroid combined with cyclosporine treatment, and the patient's condition was stable during follow-up.

Objective To observe the effect of Danshen injection (DSI) on pulmonary fibrosis in silicosis mice, and to analyze the differential metabolic pathway on pulmonary fibrosis in silicosis using DSI by urine metabolomics. Methods The specific pathogen free C57BL/6J mice were randomly divided into control group, silicosis model group, DSI prevention group and DSI treatment group. The mice in the last three groups were given 1 mL silica suspension with a mass concentration of 50 g/L by the one-time non-exposed tracheal method, and the mice in the control group were not given any treatment. Subsequently, mice in the DSI prevention group and the DSI treatment group were given intraperitoneal injection of DSI with a dose of 5 mL/kg body weight from 24 hours after exposure to dust and from the 29th day after exposure to dust, respectively, once per day until the 56th day after exposure. Mice in the other two groups were not treated. After DSI intervention, the lung histopathological changes of mice in all groups were evaluated. The components of mouse urine metabolites were analyzed using ultra-high performance liquid chromatography-quadrupole-time-of-fight mass spectrometry method. Human Metabolome Database was used to screen the potential differential metabolites (DMs). The related metabolic pathways were analyzed using MetaboAnanlyst 5.0 Web analytics platform. Results The result of hematoxylin-eosin staining and Van Gieson staining of mouse lung tissues showed that the pulmonary alveolar structure destroyed, typical fibrotic nodules appeared, collagen fiber deposition increased, and clumpy accumulation in the silicosis model group, compared with the control group. Compared with the silicosis model group, the degree of pulmonary alveolar inflammation and fibrosis in the lung tissues of mice in the DSI prevention group was obviously reduced to close to the control group, while pulmonary alveolar inflammation and fibrosis in the lung tissues of mice in the DSI treatment group were also reduced, although the outcome was not as good as that in the DSI prevention group. The result of urine metabolomics analysis identified four DMs in the model group and control group, seven DMs were identified in the DSI prevention group and silicosis model group, seven DMs were identified in the DSI treatment group and silicosis model group. A total of three DMs pathways related to pulmonary fibrosis in silicosis model group and the protective effect of DSI prevention group were identified, including D-arginine and D-ornithine metabolism, folic acid biosynthesis and metabolism, pantothenate and succinyl coenzyme A biosynthesis pathways (all P<0.01). Conclusion DSI treatment in any time point can interfere the process of pulmonary fibrosis in the silicosis mice, while the interference is more effective in the DSI group treated right after dust-exposure. DSI interferes with the urinary metabolism pathway of silicosis mice, and the D-arginine and D-ornithine metabolism, folic acid biosynthesis and metabolism, pantothenate and succinyl coenzyme A biosynthesis pathways may participate in the inhibiting process of early pulmonary fibrosis in silicosis mice by DSI.

Objective:To explore the relationship between input and output of occupational health funds, and to provide basis for relevant departments to make decisions.Methods:In September 2018, a state-owned iron ore in Hebei Province (mining history of more than 10 years, which can represent the general type of iron ore) was selected as the research object. Through the investigation and collection of enterprise general situation, occupational health input, loss and output related indicators, the iron mine occupational health expenditure input-output table and model were established, and the digital relationship between the investment and output was solved by MATLAB software.Results:The labor consumption in the departments of underground mining, open pit mining, crushing and rock discharging, transportation, tailings and mineral processing (taking labor wages as reference) were 756.46, 1.281.78, 987.61, 1 570.71, 50.956 and 18.9116 million yuan/year respectively. The output value of each sector is 11 207.19, 18 989.95, 15 176.40, 25 294.00, 7.704.94 and 280.1797 million yuan/year respectively. The ratio of health input to total output was 0.004 5, and the ratio of occupational health input to output was 1/0.046.Conclusion:The input-output table model of occupational health in iron mine can reflect the relationship between input and output of occupational health funds. The input situation of the coal mine is poor, and the input does not bring obvious occupational health benefits.
