Homeostasis between the host and viruses is naturally maintained.On the one hand,the immune system activates the immune re-sponse to kill or eliminate viruses;on the other hand,the immune system controls the immune response to maintain immune homeostasis. The cause of persistent infections with hepatitis viruses such as HBV and HCV is that viral molecules damage the immune system of the host and their variants escape immune clearance.Long-term coexistence of the host and viruses is the process involving various immune cells and molecules and is the result of homeostasis maintenance in antiviral immune response.The immune homeostasis maintained during persis-tent infections with hepatitis viruses is analyzed by the cellular and molecular mechanisms.

Objective To discuss the effect of health education to family members of patients with chronic heart failure. Methods 150 patients with family members as accompanies were divided into the observation group and the control group with 75 patients in each group. Health education was given to patients as well as their family members in the observation group, while health education was given only to the patients in the control group. The mastering of disease-related knowledge by family members of the observation group was observed after 15 days. The rehospitalization of the two groups by telephone follow-up was carried out six months after discharge. Results The mastering of disease-related knowledge by family members of the observation group was better compared with before health education. The rehospitalization rate of the observation group was 13.3%, which was lower than 44.0% of the control group. Conclusions Health education to family members of patients with chronic heart failure can increase treatment effect of patients, decrease disease relapse and lower rehospitalization rate.

Objective: To establish a rapid method for the simultaneous determination of seven yellow pigments (tartrazine, sunset yellow, brilliant yellow, orange II, auramine O, astrazon orange G, and basic orange) which were illegally added into Chinese materia medica (CMM). Methods: The sample was extracted with ultrasonic by 70% ethanol, separated on a reversed phase C18 chromatographic column by gradient elution using a mobile phase made up of acetonitrile and 0.05 mol/L ammonium acetate solution, and then detected by diode array detector in the wavelength of 432 nm and mass spectrometry detector with ESI+ ion source. Results: Under the condition of the above chromatography and mass spectrometry, the separating degree, specificity, and durability of the seven yellow pigments were good. RSD of precision was between 0.4%-1.8%. Above pigment solution was stable in 24 h and RSD < 1.9%. The recovery rates of accuracy were between 95.1%-102.9%. The limits of detection (LODs) were in the range of 2-31 μg/kg, and the RSD of repeatability was in the range of 0.3%-1.4%. Auramine O was detected in three batchs of CMM for sale. Conclusion: This method is simple, rapid, reproducible and has high sensitivity, which can be used for the determination of seven yellow pigments illegally added into dyed CMM, and it can provide the reference or help for relative company and State Food and Drug Administration in controlling the quality of CMM.

Objective: Based on the advantages of representation of herb components group clustering by characteristic spectrum integrity, to study the in vitro dissolution behavior of Daidai Flavones Dropping Pills (DFDP), and to evaluate the synchronization release situation of group clustering. Methods: Rotating basket method and HPLC characteristic spectrum were employed to evaluate the group clustering dissolution and the release characteristics of DFDP in different dissolution media (pH 1.2 hydrochloric acid solution, pH 4.5 acetic acid-sodium acetate buffer, pH 6.8 phosphate buffer, and distilled water). The single exponential, logarithmic distribution and Weibull equation model were applied to fit the dissolution curves. Results: The similarity factor (f2) of the dissolution curves of nine common peak components in characteristic spectrum of DFDP was over 50; In addition the f2 of neohesperidin and naringin was 94.86, which indicated that the group clustering of DFDP had similar dissolution curves and synchronization release characteristics. Meanwhile the dissolution mechanism of group clustering of nine common peak activity composition was following the Weibull equation model. Conclusion: The established method is simple, rapid, and stable, which provides an experimental basic for in vitro analysis and quality evaluation of DFDP.

In recent years,stem cell transplantation for the treatment of ischemic stroke has become a hot topic.However,since embryonic stem cells (ESCs) transplantation is limited by the ethics and law,stem cell research was once in trouble.Induced pluripotent stem cells (iPSCs) are a class of cells by introducing the specific transcription factors into somatic cells,which have the similar characteristics with ESCs,and also avoid the ethical issues and immunological rejection,making them become the most ideal replacer of ESCs.Although the current research on iPSCs has made some progress,their induction efficiency and safety issues remain to be resolved.This article reviews the status quo,mechanisms,and problems faced in clinical practice for iPSCs transplantation in the treatment of ischemic stroke.

Objective To summarize the value of early mechanical ventilation plus continuous vacuum suction in treatment of serious pulmonary contusion.Methods Forty-eight cases of severe pulmonary contusion were assigned to mechanical ventilation plus continuous vacuum suction (observation group,n =20) and mechanical ventilation plus discontinuous vacuum suction (control group,n =28)according to the random number table.Modes of mechanical ventilation were synchronized intermittent mandatory ventilation (SIMV),pressure support ventilation (PSV),and positive and expiratory pressure (PEEP).Changes in blood gas analysis,mechanical ventilation time,and associated complications were compared between groups.Results At ventilation time of 6 and 24 hours,PaO2 in observation group was (100.36 ± 5.90) mmHg and (105.34 ± 7.40) mmHg respectively,with significant differences from (75.36 ± 8.95) mmHg and (76.36 ± 8.35) mmHg in control group (P ＜ 0.01).At ventilation time of 24 hours,PaO2/FiO2 was (283.50 ± 15.20) mmHg in observation group and (201.50 ± 10.20) mmHg in control group (P ＜0.01).Mechanical ventilation time and PEEP at ventilation time of 48 hours in observation group was (3.2 ± 1.1) days and (4.5 ± 2.3) cmH2 O,with significant differences from (6.5 ± 2.8) days and (8.5 ± 2.5) cmH2O in control group (P ＜ 0.01).Associated complications of the two groups revealed no significant difference (P ＞ 0.05).Conclusion Early mechanical ventilation with sustained vacuum suction is effective to keep airway clear,improve oxygenation index,decrease PEEP level,and control the duration of mechanical ventilation,but may not lower the risks of ventilator-associated pneumonia and pulmonary atelectasis.
