In order to discover the mechanism of Xuebijing oral effervescent tablet (XBJOET) to treat infectious diseases, the effect of XBJOET on endotoxin induced rabbit fever and disseminated intravascular coagulation (DIC) was investigated. Auricle microcirculation in rabbit was detected by laser speckle blood perfusion imager system; coagulation function was measured by coagulation analyzer, fibrinolytic system was quantified by Elisa assay and micro thrombosis in tissues was observed with HE staining under light microscope. The results demonstrated that the body temperature of rabbit decreased significantly at 1-3 h after administration with 4.8, 2.4 and 1.2 g x kg(-1) XBJOET to endotoxin induced DIC rabbit model, the auricle microcirculation blood flow in model group (54.45 +/- 14.53) PU was lower than that in control group (77.18 +/- 12.32) PU. The auricle microcirculation blood flow increased markedly and there was significant difference between model group and 1.2 g x kg(-1) XBJOET group. There was significant difference between model group and control group in the content of PAI1 and FIB. The PAI1 levels in model and control groups were (30.48 +/- 2.46) ng x mL(-1) and (20.93 +/- 3.25) ng x mL(-1), respectively. The FIB levels in model and control group were (3.34 +/- 1.09) g x L(-1) and (4.84 +/- 1.10) g x L(-1), respectively. The content of PAI1 in rabbit plasma decreased notably, there were significant differences between model group and 4.8, 2.4 g x kg(-1) XBJOET groups. On the contrary the content of FIB increased. XBJOET possessed pharmacological activities of curing infectious fever and DIC, the mechanism of which is related to amelioration of microcirculation disturbance, inhibition of fibrinolytic system activation and coagulation and micro thrombosis elimination.

It is to investigate the effect of two kinds of Houttuynia Cordata Injection on preventing and treating H1N1 influenza virus infection in mice. Pneumonia model was set up by intranasal infection of the normal and immunocompromised mice with influenza virus FM1 and PR8. The two injections were administered before and after the administration of virus, separately, and the lung index was observed. The results showed that the two preparations have obvious therapeutic effect on normal mice infected with influenza virus FM1 and PR8. And to FM1, the new injection's effect is better at small dosage. The results also showed that the two preparations have obvious prophylactic effect on immunodepressed mice infected with influenza virus FM1 and PR8. And to PR8, the old injection's effect is better at small dosage. Houttuynia Cordata Injection can improve the mice pneumonia caused by influenza virus H1N1 and decrease the lung index markedly. It has a remarkable preventive and therapeutic effect on H1N1 influenza virus in mice.

This study is to investigate the treatment of Jin Chai antiviral capsule for influenza virus FM1/47 (H1N1) infection. The model of pneumonia was established by dropping influenza virus into the nose of normal mice, real-time PCR and Western blot technique were used to detect the virus load and the interferoninducible transmembrane protein3 (IFITM3) in lung of mice at the 1st day, 3rd day, 5th day and 7th day after affected. The results showed that Jin Chai antiviral capsule in large, middle, small dose groups can decrease virus load significantly at each time point, after being affected (P<0.05, P<0.01), Jin Chai antiviral capsule can increase the interferoninducible transmembrane protein3 in lung of mice, large dose groups are significantly higher in expression of IFITM3 compared with model group at each time point (P<0.05, P<0.01). Middle dose groups are significantly higher in expression of IFITM3 compared with model group at the 3th day and the 5th day (P<0.05), small dose groups are significantly higher in expression of IFITM3 compared with model group at the 3th day (P<0.05). It can be concluded that Jin Chai antiviral capsule exerts antiviral effects against influenzavirus by raised expression of IFITM3.

Objective:Based on the cost-effectiveness,it aimed to assess the health benefits amd economic value of screening,di-agnosis,treatment,and optimal delicacy management of liver disease in hepatocellular carcinoma(HCC)patients.Methods:A Deci-sion tree-Markov model was developed to compare the cost-effectiveness of HCC screening and long-term surveillance versus no screening in population at risk from the health care system perspective.Results:It is found that HCC screening was a cost-effective approach compared to no screening(Incremental Cost-Effectiveness Ratio[ICER]:17 790 yuan/QALY).Scenario analyses suggested that initiating HCC screening at the age of 40,as recommended by clinical guidelines,and implementing long-term surveillance based on risk stratification were more cost-effective.Conclusions:For the implementation of HCC screening programs,attention should be paid to improving participation and compliance among the population at risk,incorporating advanced screening methods,improving management efficiency with digital tools,and introducing innovative payment methods to reduce economic burden.

This paper summarized clinical experience of treating recurrent subacute thyroiditis based on the theory of internal toxin. It is believed that the core pathogenesis of recurrent subacute thyroiditis is the accumulation of internal toxin. The dysfunction of the spleen in transportation leads to the internal retention of turbidity， which serves as the basis for the formation of toxins. The combination of fire， dampness， and toxins is the key to the disease mechanism. Prolonged accumulation of dampness and turbidity leads to the formation of phlegm， fire， and stasis， and prolonged accumulation of pathogenic factors transforms into secondary toxins. For patients with severe fire， dampness， and toxins， the treatment focuses on dispersing stagnated liver qi， invigorating spleen， and differentiation treatment of fire and water， using a self-designed Chaihu Jiedu Decoction （柴胡解毒饮）. For patients with spleen deficiency and toxin accumulation， the treatment focuses on invigorating the spleen， eliminating turbidity， and cutting off the source of toxins， using a self-designed Shiwei Baizhu Powder （十味白术散）. For patients with yang deficiency and toxin stagnation， detoxification is combined with warming yang， nourishing blood， and supporting toxin expulsion， using a self-designed Heyang Baidu powder （和阳败毒散）.
