Objective To investigate the effects and toxicity of pirarubicin and chemotherapy regimen in treatment of malignant lymphoma in the elderly. Methods 50 cases(over 60 years of age) with non Hodgkin's lymphoma collected in Lishui Central Hospital of Zhejiang province from January 2011 to January 2013 were randomly divided into control group(n=25)and experimental group(n=25). Experimental group were received CTOP chemotherapy, control group were received the standard CHOP chemotherapy, vomiting, stomach, blood pressure, blood glucose control and other appropriate symptomatic treatment were adopted according to the speciifc circumstances of each patient in both two groups. Regular inspection were given to all patients, and bone marrow suppression, treatment of lymphoma, complications and other indicators were observed. Results Complete remission in experimental group after treatment was 13 cases, accounted for 52%within group, partial remission were 9 cases, accounted for 36%. The total effective number was 22, and the rate was 88%. Complete remission in control group after treatment was 8 cases, accounted for 32%within group, partial remission were 5 cases, accounted for 20%. The total effective number was 13 cases, and the rate was 52%. Bone marrow suppression in experimental group was signiifcantly less than control group (P<0.05). Conclusion Elderly patients with malignant lymphoma in chemotherapy plus pirarubicin can improve the therapeutic effect, reduce bone marrow suppression and complications.

Objective To investigate the effect of total glucosides of paeony(TGP) on hepatic dysfunction caused by Methotrexate (MTX) and Leflunomide (LEF) in patients with moderate or severe rheumatoid arthritis (RA).Methods From July 2010 to February 2011,204 cases with definite-diagnosed rheumatoid arthritis were included in three hospitals in Anhui province.All these patients suffered from moderate or severe rheumatoid arthritis and they were divided randomly into two groups,the therapeutic groups were treated with TGP combined with MTX and LEF and the control group were treated without TGP.The incidence of hepatic dysfunction was observed.Statistical anylysis was carried out by using t test and x2 test.Results One hundred and ninty-four patients had completed observation for at least 12 weeks.In the therapeutic group,only 10 of 105 patients had hepatic dysfunction compared to 31 of 89 patients in the control group.The incidence of hepatic dysfunction of the therapeutic group was significantly lower than the control group.After 12 weeks treatment with TGP,the effective respohse rates of the therapeutic group was 81.9％,which was higher than 74.6％ in the control group.The good response rate in the therapeutic group was 21.6％,which was better than 11.7％ in the control group.Although the difference between the two groups was not statistically significant,we could observed the tendency of increasing in effectiveness and the good response rate in the therapeutic group when compared with the control group.Conclusion TGP can decrease the incidence of hepatic dysfunction during the treatment with MTX and LEF,and it may improve the therapeutic effecacy of patients with RA.

AIM: To obtain eukaryotic expression vector of Chinese prostate-specific membrane antigen. METHODS: Chinese prostate-specific membrane antigen (PSMA) cDNA was amplified by RT-PCR from prostate cancer tissues, then cloned into eukaryotic expression vector pcDNA3 0 and sequenced. RESULTS: Seven bases in Chinese PSMA cDNA sequence were found different from those reported by Israeli, which lead to two different amino acids. CONCLUSION: We have obtained the PSMA cDNA, and the recombinant eukaryotic expression vector was successfully constructed. The study lays foundation for DCs vaccine modified by PSMA gene for the treatment of prostate neoplasms.

Objective To evaluate the effects of a traditional Chinese medicine Rubia cordifolia L.aqueous extract (RCAE) on body weight, fat mass and parameters of glucose and lipid metabolism in high fat diet (HFD)-induced obese rats and its mechanism.Methods pGL3-Enhancer-PPARγ2 (625 bp)-Luc plasmid, a luciferase reportergene expression plasmid containing PPARγ2 promoter was constructed and stably transfected 3T3-L1 preadipocytes were established.PPARγ2 promoter`s activities in these cells were detected after administration with different concentration (0.1 mg/L~1 000 mg/L) of RCAE or with 100 mg/L RCAE for different action time.PPARγ2 mRNA expression in human adipocytes were detected after administration with 100 mg/L RCAE.Meanwhile, HFD-induced obese rats were administrated with low or high dose RCAE to investigate the effects of RCAE on serum glucose, lipid and insulin levels, body weight, visceral fat mass and so on.Results 10 mg/L RCAE could increase luciferase expression in 3T3-L1 cells to 1.43 folds of that in control group (P<0.01) and it reached 3.24 folds of that in control group when the concentration of RCAE was 1000 mg/L (P<0.01).With the administration with 100 mg/L RCAE, the luciferase activity of 3T3-L1 cells peaked at 28 h where it was 2.72 folds of that in control group (P<0.01), and the expression of PPARγ2 mRNA in human adipocytes increased to 2.27 folds of that in control group (P<0.01).Compared with HFD group, low dose RCAE significantly reduced the fasting insulin level, HOMA-IR and visceral fat mass (P<0.05).Conclusions Low dose RCAE significantly reduces the visceral fat mass and ameliorates insulin resistance in HFD-induced obese rats.The potential mechanism may be explained by the stimulation of PPARγ2 promoter activities and the increased expression of PPARγ2 gene.

Objective: To understand the satisfaction of the residents in Hangzhou with primary health care services and its influencing factors, so as to provide basis for improving the quality of primary health care services.

A self-designed electronic questionnaire for primary health care services in Hangzhou was used to collect the demographic information, the utilization of primary health care institutions, the scores of the indicators of primary health care services and the satisfaction. The ordinal and multinomial logistic regression model was conducted to analyze the influencing factors for the satisfaction with primary health care services. Results: Totally 1 600 questionnaires were issued, 1 454 valid ones were collected, and the response rate was 90.88%. Five ( 0.34% ) residents were very dissatisfied, 16 ( 1.10% ) residents were dissatisfied, 153 ( 10.52% ) residents were generally satisfied, 780 ( 53.65% ) residents were satisfied, and 500 ( 34.39% ) residents were very satisfied with primary health care services. The ordinal and multinomial logistic regression analysis showed that basic medical insurance for urban employees ( OR=0.514, 95%CI: 0.370-0.714 ) , no health records in primary health institutions ( OR=0.528, 95%CI: 0.331-0.844 ) or unknown ( OR=0.524, 95%CI: 0.331-0.829 ) , the queuing time spent for getting medicines ( OR=0.698, 95%CI: 0.531-0.917 ) , ways of getting medicines (OR=0.639, 95%CI: 0.452-0.903 ) and completeness of testing equipment ( OR=1.315, 95%CI: 1.012-1.710) were influencing factors for the satisfaction with primary health care services. Conclusions The residents in Hangzhou are generally satisfied with the primary health care services, which are associated with the type of medical insurance, the condition of health records in primary institutions, the queuing time spent for getting medicines, the ways of getting medicines and the completeness of inspection equipment.

Objective To test anti-Sa antibody in different autoimmune connective tissue diseases and analyze the relationship between Sa antibody and clinical manifestations and laboratory tests in rheumatoid arthritis.Method Sa antigen was extracted from human placenta. Anti-Sa antibody was tested in 40 normal people and 478 connective tissue disease (CTD) patients using Western Blotting (WB). Conclusion Anti-Sa antibody was a new auto-antibody for the diagnosis of RA. Anti-Sa antibody positive patients seem to have more serious inflammation and more advanced disease process.

Objective:To investigate the current status and influencing factors of kinesiophobia in adult burn patients.Methods:A single center cross-sectional research method was conducted. A total of 170 adult burn patients, meeting the inclusion criteria, were admitted to the Department of Plastic Surgery and Burns of the West China Hospital of Sichuan University from October 2018 to December 2019. On admission, the self-made general information questionnaire was used to investigate the gender, age, education level, marital status, payment method of medical expenses, injury factors, and total burn area of patients. One month after admission or before discharge, the presence and degree of kinesiophobia of patients were evaluated by the Tampa Scale for Kinesiophobia (TSK), their pain degrees (results averaged) at the time of burn, debridement and dressing change, after burn operation, and at rest were evaluated by the Visual Analogue Scale, their social support levels were evaluated by the Social Support Revalued Scale, and their degrees of anxiety and depression were evaluated by the Hospital Anxiety and Depression Scale. According to the TSK score, the patients with score >37 points were included into kinesiophobia group, and the patients with score ≤37 points were included into non-kinesiophobia group. The general information of patients in the two groups, as well as the pain score, social support level score, anxiety score, and depression score mentioned above, were recorded. Data of patients between the two groups were statistically analyzed with unifactor analysis including chi-square test, independent sample t test, and Mann-Whitney U test. The factors with statistically significant differences in unifactor analysis were used as variables for multivariate logistic regression analysis to screen out the independent influencing factors of kinesiophobia in adult burn patients. Results:Questionnaires and scales of 170 patients were collected, and the recovery rate was 100%. The data of two patients complicated with cranial fracture aggravation were removed, and 168 valid data were obtained, with the effective rate of 98.82%. Among the 168 patients, 88 were male (52.38%) and 80 were female (47.62%), aged from 18 to 71 (41±6) years. Most of the patients had secondary school education or below, were married, and with no out-of-pocket medical expenses. The main factors of injury were flame and hydrothermal fluid, and the total burn area was 2%-75% ((28±5)%) total body surface area. The TSK score was (41±5) points, the pain score was 4.0 (2.6, 7.0) points, the social support level score was (40±5) points, the anxiety score was 8.5 (7.0, 13.0) points, and the depression score was 9.5 (6.5, 12.0) points. A total of 98 patients had kinesiophobia, and the incidence of kinesiophobia was 58.33%. There were no statistically significant differences in gender, age, educational level, marital status, or injury factors of patients between kinesiophobia group and non-kinesiophobia group ( P>0.05). The percentage of out-of-pocket expenses, total burn area, pain score, anxiety score, and depression score of patients in kinesiophobia group were significantly higher than those in non-kinesiophobia group ( χ2=6.402, t=2.39, Z=-8.05, -6.68, -7.89, P<0.05 or P<0.01), and the social support level score of patients in kinesiophobia group was significantly lower than that in non-kinesiophobia group ( t=5.22, P<0.01). The multivariate logistic regression analysis showed that total burn area, pain score, social support level score, anxiety score, and depression score were the independent influencing factors for the development of kinesiophobia in adult burn patients (odds ratio=0.79, 1.45, 0.78, 1.15, 1.17, 95% confidence interval=0.80-0.92, 1.24-1.74, 0.65-0.91, 1.06-1.29, 1.03-1.24, P<0.01). Conclusions:The incidence of kinesiophobia in adult burn patients is high, and the degree of kinesiophobia is mainly affected by total burn area, pain, social support level, anxiety and depression degrees, and so on. Thus these factors should be taken into consideration when designing interventions to reduce the incidence and degree of kinesiophobia.

Objective:To explore the psychological experience of front-line nurses combating the COVID-19 epidemic and provide suggestions and evidence for clinical interventions.Methods:From January 25th to 27th, 2020, a semi-structured interview was conducted using phenomenological research methods on 10 front-line nurses combating COVID-19 from a Class Ⅲ Grade A hospital, and Giorgi phenomenological analysis was used to analyze the data.Results:The psychological experience of clinical front-line nurses in this study could boil down to three themes: negative psychological experience (fear, worry, and fatigue) , insufficient ability to cope with public health emergencies (insufficient awareness of disease, and insufficient emergency rescue nursing skills) , and rational understanding of the fight against the epidemic (a sense of mission and confidence) .Conclusions:Clinical front-line nurses have different levels of negative psychological experience and lack the ability to respond to public health emergencies. Hospitals should strengthen psychological assistance and humane care for clinical front-line nurses, promote training for emergency disaster rescue nursing, improve hospital emergency management capabilities, and ensure efficient rescue work.

Objective : To analyze the status and influencing factors of the intention of people aged 18 to 25 years to primary medical institutions and their satisfaction for health services in Zhejiang Province, so as to provide basis for the improvement of health services in primary medical institutions. Methods: During November and December in 2019,the 18-25 year-old people in Zhejiang Province were recruited to investigate the general information, intention to seek medical advice and satisfaction for health services in primary medical institutions through WeChat. Logistic regression was performed to analyze the influencing factors of the intention and the satisfaction. Importance matrix was used to analyze the key drivers of the satisfaction. Results: Among the 620 people surveyed, with a response rate of 93.37%, 142 (22.90%) chose primary medical institutions for advice. Actually 516 (83.23%) people went to primary medical institutions last year, and 384 ( 74.42% ) of them were satisfied with the health services. The results of multivariate logistic regression analysis showed that the people aged 18-25 years who were under the new rural cooperative medical care system ( OR=3.062, 95%CI: 1.745-5.373 ) and who had records in community health centers ( OR=0.547, 95%CI: 0.308-0.970 ) were more likely to go to primary medical institutions for medical advice; the ability of doctors ( OR=1.478, 95%CI:1.168-1.871 ) ,the drug notification by medical staff ( OR=1.308, 95%CI: 1.065-1.606 ) , routine examination items ( OR=1.523, 95%CI: 1.227-1.889 ) , the ways of payment ( OR=1.168, 95%CI: 1.017-1.340 ) , the comfort of environment ( OR=1.785, 95%CI: 1.437-2.219 ) and the bulletin boards of health knowledge ( OR=1.302, 95%CI: 1.086-1.561 ) were associated with the satisfaction. The results of importance matrix analysis showed that the ability of doctors and routine examination items were the priorities to improve, followed by the drug notification by medical staff; the comfort of environment had competitive advantages; the ways of payment and the bulletin boards of health knowledge needed to be further analyzed. Conclusions The 18-25-year-old people in Zhejiang Province were less intended to seek medical advice in primary medical institutions, which was associated with the type of medical insurance and records in community health centers. They were satisfied with the health services, the ability of doctors and routine examination items were the key drivers.
