OBJECTIVETo observe the effects of Rubiae Radix et Rhizoma (RRR) and carbonized Rubiae Radix et Rhizoma (CRRR) on the acute blood stasis rat model, and reveal their differences in efficacy.
METHODThe acute blood stasis model was induced by subcutaneously injecting adrenaline hydrochloride and soaking in ice water. Yunnan Baiyao was used as the positive control drug, and administered for consecutively seven days. This model was adopted to observe the effect of high, middle and low dose RRR and CRRR groups on hemorheology, thrombin activity, and blood platelet system.
RESULTRRR could significantly reduce the wholeblood viscosity and plasma viscosity of blood stasis rats under different shear rates, and showed certain two-way regulating function in hemostasis. It also showed certain effect on ADP-induced platelet aggregation rate, but which was lower than CRRR. CRRR achieved the main hemostatic mechanism by stimulating intrinsic and extrinsic blood coagulation and fibrinogen, and could significantly enhance the platelet aggregation rate of rats in the acute blood stasis model (P <0. 01).
CONCLUSIONRRR had the effect of removing blood stasis and hemostasis, while CRRR mainly has the hemostatic effect. This further demonstrates the traditional processing theory of "promoting blood circulation with crude herbs and stopping bleeding with processed herbs".

Objective To analyze the surveillance results of schistosomiasis and understand the transmission situation in Hu?bei Province in 2014. Methods According to the Scheme of Schistosomiasis Surveillance in Hubei Province(the 2009 edi?tion),207 endemic sites were selected,where the schistosome infections of residents and livestock,and the distribution of On?comelania hupensis snails were investigated. Results In the 207 sites,there were 27 sites without positive results of the blood tests and 129 sites without positive results of the stool tests. The infection rates of residents and cattle were 0.17%and 0,respec?tively. The density of living snails was 0.339 3 snails/0.1m2,the rate of living snails was 10.12%,and the infection rate of snails was 0. The infection rate of residents in the inner embankment type was 0.22%,higher than the rates in the other types. In differ?ent age groups,the infection rate in the 50-59 years age group was higher than the rates in other age groups. The infection rates of residents in farmer and fisherman were higher than those in the other occupation groups. The infection rate of floating people was 0,and no acute schistosomiasis patients were found. Conclusion The endemic situation of schistosomiasis has decreased obviously in Hubei Province,and the whole province has achieved the criteria for transmission control of schistosomiasis.

Objective To grasp the distribution and epidemiology of confirmed cases of schistosomiasis in Hubei Province, so as to provide the evidence for promoting the prevention and control work. Methods The confirmed cases of schistosomiasis in Hubei Province from 2010 to 2014 were epidemiologically investigated,and the prevalence characteristics and main influenc?ing factors were analyzed. Results A total of 10 102 confirmed cases from 2010 to 2014 were surveyed. There were 1 062 local infected patients,accounting for 10.51%and including 354 repeated infections and 17 newly infected. There were 290 foreign?infected patients,accounting for 2.87%,with 206 repeated infection cases and 84 newly infected. There were 8 750 historical patients,including 2 229 patients who leaked the former schistosomiasis investigations,accounting for 22.06%;570 patients missed treatment,accounting for 5.64%;3 640 patients were treated with non?standard therapy,accounting for 36.03%;2 311 patients were treated with poor medication efficacy,accounting for 22.88%. The multivariate non?conditional Logistic regres?sion,targeting at confirmed cases in 2014,showed that,for the leaking investigations,the potential risk factors included the age,educational level,and latrine renovation(b>0,OR>1),the protective factors were the times of previous treatment,cat?tle feeding in villager team,and Oncomelania hupensis snails in surroundings(b<0,OR<1);for the treatment?missing,the age,educational level,snails in the surroundings of residence were risk factors(b<0,OR<1);for the substandard treat?ment,the risk factors included the occupation and snails in the surroundings of residence(b>0,OR>1),and the educational level and snails in the own field were protective factors(b<0,OR<1). Conclusion The epidemiological investigation on the confirmed cases of schistosomiasis could grasp the epidemic factors so as to improve the management and carry out the scientific control.
