Objective To investigate the hand washing state and its influencing factors in patients undergoing infusion in outpatient clinic in order to adopt measures to enhance the patients' consciousness of hand hygiene. Methods 300 adult patients undergoing infusion in outpatient clinic were investigated.The bacteria condition before and after washing hands was observed. The condition and washing apparatus in the infusion room were also evaluated. Results The bacteria amount in the hands of patients undergoing infusion was 20 to 36 times higher than the standard level. The washing apparatus was simple and did not reach the standard requirement. Conclusion We should strengthen the propaganda of hand hygiene knowledge to patients undergoing infusion and improve their recognition of the importance of hand washing. The hospital should improve the washing facilities to reduce hospital infeciton.

Ultrasound, as a mechanical wave with frequencies > 20 kHz, needs an elastic medium to transmit energy, and it can safely penetrate into the tissues without significant attenuation. Sonodynamic therapy is a new noninvasive therapy based on ultrasound, and it mainly uses low-intensity ultrasound to activate sonosensitizers to produce cytotoxic reactive oxygen species to kill cells. Compared with photodynamic therapy, sonodynamic therapy overcomes the limitation of low penetration depth of light for deep tumors. In addition, sonodynamic therapy can be combined with photothermal therapy, chemotherapy, immunotherapy and gas therapy for synergistic therapy of tumors. This review aims to discuss the latest development of sonodynamic therapy in the field of tumor treatment.

OBJECTIVE To investigate the antimicrobial-resistant profile of Staphylococcus aureus isolated from clinical specimens. METHODS The isolates of S.aureus were obtained from all kinds of clinical specimens by routine methods.The identification and susceptibility test of the isolates were determined by Automated Microbiology Analyzer.Disk-diffusion was used for detecting meticillin-resistant Staphylococcus aureus(MRSA). RESULTS The isolates were mainly isolated from sputa and urines.62.1% of isolates were referred as MRSA.All isolates of MRSA were resistant to ampicillin/sulbactam,penicillin G and cefazolin.No isolates of MSSA were resistant to above drugs.All isolates were susceptible to nitrofurantoin and vancomycin.The resistant rates of the isolates of MRSA to clindamycin,erythromycin,gentamicin,tetracycline,rifampin,sulfamethoxazole and levofloxacin were 70.7%,86.6%,87.8%,82.9%,42.7%,30.5% and 91.5%,respectively,those of MSSA were 31.3%,41.7%,20.8%,20.8%,10.4%,29.2% and 6.3%. CONCLUSIONS The antimicrobial resistance of MRSA is serious,but the antibiotics have high activity to the isolates of MSSA except penicillin G in vitro.Vancomycin has very high activity to the isolates of MRSA in vitro.

In addition to the structural genes of the coronavirus genome, S, E, M, and N, there are several additional genes called "group-specific or accessory genes". Their gene products are designated as "accessory proteins", as reports to date make it clear that these proteins are not essential for virus replication in vitro. Nevertheless, many of these genes are still maintained in the virus genome under selective pressure, suggesting that they might play a very important role in the survival of the virus in the natural environment of the infected host. This review will summarize the research progress in the functions of coronavirus accessory genes.

Objective: There is controversy about the prognostic factors for early stage Hodgkin's lymphoma (HL). The aim of this study is to investigate the prognostic factors for HL at early stage. Methods: The clinical data from 188 patients were analyzed retrospectively. One hundred patients (53.2%) received radiotherapy (RT) alone and 88 cases (46.8%) received combined chemotherapy and radiotherapy. The 5-year and 10-year overall survival (OS) and disease-free survival (DFS) rates were estimated by Kaplan-Meier survival analysis with log-rank test. The prognostic factors were determined by COX proportional hazards model. Results: The 5-year and 10-year OS rates were 84.5% and 76.3% for patients who received radiotherapy alone, respectively; they were 96.2% and 96.2% for those patients who received combined chemotherapy and radiotherapy, respectively (P = 0.340). The 5-year and 10-year DFS rates were 84.7% and 76.9% for patients who received radiotherapy alone, respectively; they were 93.4% and 71.8% for patients who received combined therapy, respectively (P = 0.015). Univariate analysis indicated that tumor size and patients' age (with the cut-off of 40 years old) were the prognostic factors for predicting OS (P = 0.002 and 0.001) and DFS rate (P = 0.033 and 0.019). The pathological type had marginal significance in predicting OS rate (P = 0.072) and B symptoms had marginal significance in predicting DFS rate (P = 0.072). Multivariate analysis indicated that five factors including age (P =0.022), gender (P = 0.036), tumor size (P = 0.024), the drainage areas of involved lymph nodes (with the cut-off of 3 areas) (P = 0.060), and clinical stage (P = 0.028) had significance or marginal significance for predicting HL. Conclusion: Being more than 40 years old, male, clinical stage II, bulky disease, and the number of involved mediastinum and lymph node regions ≥3 are the independent prognostic factors for patients with early HL.

Objective To investigate the pathogenesis of hepatogenic diabetes.Methods The fasting and 2-hour postprandial plasma glucose,fasting sertum insulin,glutamate decarboxylase antibody,insulin release index (IRI)and insulin sensitivity index(ISI)Was determined and analyzed in 135 liver cirrhosis patients.Results The incidence of hepatogenic diabetes wag 39.3%(53/135)in liver cirrhosis patients.The incidence of hepatogenic diabetes in post hepatitis C liver cirrhosis patients(53.3%.16/30)was muchh igher than that in post hepatitis B liver cirrhosis patients(37.1%,26/70)and alcohofic liver cirrhosis patients(31.4%.11/35)(P＜0.01).The fasting serum insulin,IRI and the positivity rate of glutamate decarboxylase antibody was much higher in hepatogenic diabetes than that in controls(P＜0.01),and ISl was much lower than that in controls(P＜0.01).Conclusions The development of hepatogenic diabetics is relsted with the etiological factor of liver cirrhosis.Besides impairment of the hepatocellular function and insulin resistance,viral infection and immunologic derangement and so on results in impairment of beta cell of islet function.Relative or absolute deficiency of insulin secretion is an important influential factor in the development of hepatogenic diabetics.
