Objective To know the rural doctors' knowledge,belief and practice on iodine deficiency disorders(IDD),as well as their capability on health education communication in Ye County,Henan Province.Methods Semi-structured interviews were conducted among 50 rural doctors in Ye County,Henan Province.Topics covered include:sales of salt purchases,daily supervision and monitoring activities of salt,the health effects of salt,the situation of rural doctors trained,the situation of rural doctors participated in health education and related recommendations.Results ①Twenty-nine of the rural doctors knew exactly the advantage of salt iodization.②Thirty-nine of the rural doctors had taken part in the half quantitative detection of salt once or twice a year and 15 of them knew the supervision activities of salt industry department.③Forty-nine of the rural doctors believed salt iodization was beneficial to health and 48 of them were willing to participate in health education on IDD.④The major ways of their acquiring health knowledge were promotional materials [54.0％ (27/50)],TV [50.0％ (25/50)],and lecture/training [24.0％ (12/50)].⑤Thirty-seven of the rural doctors had taken part in health education on IDD.They were used to use booklets [68.0％ (34/50)],promotional slogan [36.0％ (18/50)],broadcast [24.0％ (12/50)],and doctor consultation [24.0％ (12/50)].⑥Twenty-eight of the rural doctors thought the current health education on IDD was better.They hoped to reduce the price of salt,strengthen supervision,receive more training and health education on IDD.Conclusions The rural doctors remain relatively lack of knowledge on IDD.Rural doctors have the initiative and responsibility to conduct health education on IDD,but their pattern is still a one-way propagation.

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.

Qingkailing injection, Shuanghuanglian injection, baicalin, chlorogenic acid as sample, guinea pig as control, to observe the specificity of allergic response to traditional Chinese medicine (TCM) injection in BN rats and establish a suitable animal model to evaluate applicability of allergic response in BN rats and guinea pigs induced by TCM. BN rats were sensitized by TCM injection, the symptoms, the rate and degree of allergic response were observed, the level of histamine in serum and tissues were determined by ELISA assay, the rate and degree of pathological changes in target organs were observed by HE staining under light microscope. There were significant symptoms of allergic response can be in BN rats, the level of histamine in serum, lung and trachea tissues increased significantly and there were significant pathological changes in lungs and tracheas. Meanwhile, the similar symptoms of allergic response can be induced by penicillin and trichosanthin. The rate and degree of allergic response, the rate and degree of pathological changes was higher in BN rats than in guinea pigs. Compared with guinea pig, BN rat is probably more suitable animal model in evaluating allergic response to injection of TCM.
