Objective To investigate the preventive and therapeutic effects of lamivudine and entecavir on hepatitis B virus (HBV)reacti-vation among non-Hodgkin lymphoma (NHL)patients with chronic HBV infection during chemotherapy.Methods From January 2008 to April 2013,a total of 94 NHL patients with HBV infection were recruited from our hospital and divided into lamivudine treatment group and entecavir treatment group.The lamivudine treatment group received chemotherapy with lamivudine (100 mg/d),and the entecavir treatment group received chemotherapy with entecavir (0.5 mg/d).The rates of virological breakthrough,primary non -response,and virological breakthrough-related hepatitis flare were compared between groups.The t-test was used for comparison between two groups of independent samples;one-way analysis of variance was conducted for comparison between three groups of independent samples;the chi -square test was used to conduct intergroup comparison.Results For the patients with HBV DNA levels lower than 103 copies/ml before anti -HBV treatment,no significant difference was found in the rate of virological breakthrough or rate of hepatitis flare between lamivudine treatment group and entecavir treatment group (χ2 =1.03,P>0.05).For the patients with HBV DNA levels higher than 103 copies/ml before anti-HBV treatment,the lamivudine treatment group had a virological breakthrough rate of 37.5%,a primary non-response rate of 9.4%,a hepatitis flare rate of 28.1%,and a liver failure rate of 3.1%,and the aforementioned rates for entecavir treatment group were 3.1%,0, 0,and 0,respectively;there were significant differences in the rates of virological breakthrough and hepatitis flare between the two groups (χ2 =11.68,P<0.05;χ2 =10.47,P<0.05).Conclusion Among NHL patients with HBV infection whose HBV DNA levels are lower than 103 copies/ml,the preventive and therapeutic effects of lamivudine and entecavir on HBV reactivation are similar;among NHL patients with HBV infection whose HBV DNA levels are higher than 103 copies/ml,those treated with entecavir have lower rates of virological break-through and hepatitis flare than those treated with lamivudine,which helps patients have a smoother progress of chemotherapy.

Epilepsy is one of the five major neuropsychiatric diseases on which the World Health Organization focuses. New treatment methods are emerging, such as neuromodulation and radiofrequency ablation to remove lesions and precise treatment for gene mutation. However, antiepileptic drug therapy is still the first choice mostly. Since potassium bromide was applicated in epilepsy in 1857, which opened the prelude to the development of modern antiepileptic drugs, more than 20 kinds of antiepileptic drugs have been used in clinical practice. This article reviews the present status and future development of antiepileptic drugs at home and abroad.

Falling in the elderly is a major health problem and may cause severe consequences. Fall risk assessment is important for preventing and intervening fall incidence. Inertial Measurement Unit (IMU) has been introduced to evaluate motion/balance function and fall risk among the older people. Some researches indicated that it might have advantages over the usual tools, and can be used in the hospitals, communities, nursing homes, etc. IMU is a good way to measure gait variability, which may be strongly related with the risk of falls.

Coronary heart disease (CHD) is a common gerontal disease, and percutaneouse coronary interangioplasty (PCI) has already become a main treatment in CHD. However, restenosis to some extend has limited clinical application of PCI. The advent of drug eluting stents brings optimistic prospect in preventing restenosis.

With the information section of the 187th Central Hospital of PLA as an example , the paper introduces the application of the PDCA cycle model in the quality management of its information services .As a result, it finds that the service satisfaction degree after the implementation of the PDCA cycle is significantly higher than that before the implementation .It indicates that the management method with the PDCA cycle can optimize the information service process and promote the continuous improvement of information service quality .

Objective The purpose of this study was to determine and compare the hemodynamic effects of desflurane and enflurane in children.Methods Twenty-eight ASA Ⅰ-Ⅱ patients, aged 1-5 years were randomly assigned to receive either desflurane (group D) or enflurane (group E) for maintenance of anesthesia.Cardiac output was continuously monitored by transesophageal Doppler (TECO1).The stroke volume index (SVI), cardiac index (CI),heart rate (HR) and blood pressure(SBP,DBP,MAP) were determined before and during inhalation of desflurane and enflurane at 0.5,1.0 and 1.5 MAC.Results At 0.5 MAC of both agents SVI, CI and HR remained unchanged, but SBP, DBP and MAP were slightly reduced as compared to the baseline values.At 1.0 MAC of desflurane CI was increased and was higher than that in the group E. SVI and HR were significantly higher in group D than those in group E at 1.0 MAC.SBP, MAP and DBP were further reduced and the magnitude of reduction was similar between both groups.At 1.5 MAC CI and SVI were unchanged in group D but greatly reduced in group E.HR increased significantly in group D but remained unchanged in group E.There was further decrease in BP in both groups but SBP and MAP decreased more markedly in group E than in group D .Conclusions Desflurane causes less hemodynamic changes in children of 1-5 years than enflurane.

Objective To investigate the change in heat shock protein 70(HSP7O) in the brain tissue of fetal and newborn rats after prenatal hypoxic adaptation and the possible mechanism of the protective effect. Methods Twenty-two 22d pregnant Wistar rats were randomly divided into two groups: GroupⅠ(hypoxic adaptation group) and group Ⅱ(control group). The animals in group Ⅰ were placed in a tightly closed hypoxic adaptation chamber, of which the oxygen and carbon dioxide concentrations were monitored. The pregnant rats were taken out and exposed to fresh air for 5 mm when the 02 % in the chamber was reduced to 15 %, then the pregnant rats were placed back in the chamber and the above process was repeated once. The animals were then left for their natural labor. In control group the pregnant rats underwent the same process but the chamber was not tightly closed(O2 %= 21 %). Prenatal rats were delivered by cesarean section at lb. 3h, 8h, 24h, 48h, 72h, 120h and 168h after hypoxic adaptation and decapitated and brain was removed. Seven newborn rats from each group were decapitated and brain was removed for determination of HSP70 expression with immunohistochimical technique. Results No HSP7O expression was observed in the brain tissue of normal prenatal and newborn rats. HSP70 was observed in the different regions of hippocampus and cortex from 8h to 168h after hypoxic adaptation. Strongest HSP70 expression was observed in hippocampus CAl . Conclusions HSP70 plays a role in the formation of prenatal hypoxic adaptation.

[Objective]To observe the biological properties of a novel collagen/hydroxyapatite composite scaffold in vitro and to evaluate the possibility of application being used in tissue engineering for osteochondral repair.[Method]The scaffolds were constructed of collagen I and hydroxyapatite.The pore size and interpores of the scaffold were observed by scanning electronmicroscopy(SEM).The porosity was measured by liquid displacement method.Rabbit bone marrow stromal cells(BMSCs) were isolated and amplified,then inoculated onto the scaffold.By SEM scanning,the condition of the cells adhering onto the scaffold was observed.The proliferation of the cells on the scaffolds was examined using MTT method,and the growth curve was drawn.[Result]The scaffold possessed high porosity and proper pore size.The pore diameter of the collagen layer was about 90?m,the pore diameter of the HA layer was about 120?m,and the overall porosity of the composite scaffold was 75%.The proliferation of the cells on the scaffold was good.[Conclusion]The novel collagen/hydroxyapatite composite scaffold possesses desirable pore structure and good biocompatibility,and it can be used in tissue engineering for osteochondral repair.
