Objective To study the protein expressions of Fas-associated death domain protein (FADD) and caspase-8 in rats with intracerebral hemorrhage ,and the effects of erythropoietin tp reveal the mechanism of neu-m-protection by EPO. Methods 126 male SD rats were randomly divided into three groups: Sham-operated group, intracerebral hemorrhage group, and EPO group. Each group was divided into seven subgroups according to the differ-ent time points (3,6,12,24,48,72 h and 7 d). The model of intracerebral hemorrage was established in rats by in-tracerebral injection of autogenous blood. The protein expressions of FADD and caspas-8 in rats tissue around the hemorrhagic and the normal brain tissue were detected by immunohistochemistry. Results The protein expressions of FADD and caspase-8 were increased [(4.66±0.46 ) and ( 15.89±1.81)] at 3 h after intracerebral hemorrhage, and peaked at 48 h [ (35.88±4.24 ) and (45.04±3.99)], the expressions of FADD and caspas-8 in the region around hematoma in EPO group significantly decreased compared with model group[ (3.92±0.64) and (28.24±1.90), (13.32±2.01 ) and (35.08±2.82)] at 3 h and 48 h. Conclusion The protein expressions of FADD and easpase-8 are markedly increased after intracerebral hemorrhage. EPO can protect the neurons by signifi-cantly reducing the expressions of FADD and caspase-8.

Anopheles minimus was once a main malaria vector in Hainan Island and had been e-liminated basically through the campaign of indoor residual spraying launched in 1959. It again became an incriminated vector of some focal malaria outbreaks in recent years. The present study was conducted in a selected county-Danxian and a typical hilly area-Feibar in the west part of Danxian county in 1989-1990.An. minimus was found in 50% and 62. 5 % of the surveyed sites at mountainous and hilly area of Danxian county,but not found in coastal region. An. minimus was found in all 18 sites surveyed in Feibar district constituting 52% of anopheline composition. Man-biting rate made by human-baited collection was 3. 2 before midniaght and 38. 2 when collected through whole night in some sites. However, the behaviour characteristics of An. minimus has changed. It has become exophilic,exophagic, and has an equal preference for man and cattle. The vectorial capacity of An. minimus estimated by quantitative data was in accord with malaria infection rate in Feibar district ,and the malaria infection rate among the inhabitants in three types of residential quarter with different socioeconomic conditions. Malaria infection rates of residential quarter of land-reclamation outcomers, villagers and state farm residents were 10%,2. 9% and 0. 5% respectively during 40 days from July to August,1990.Owing to the fact that An. minimus has become a secondary vector only next to An. dirus, with a wide range of distribution and a considerable different characteristics in behaviour compared to that before spraying campaign , it is suggested that a malaria control programme must be seriously planned to adjust the new problem of malaria epidemiology in Hainan Province.

OBJECTIVE: To investigate the rationality of TLC identification method (3) of (R,S)-epigoitrin in Isatis indigotica stated in 2015 edition of Chinese Pharmacopeia (partⅠ) (later abbreviated as pharmacopeia), and make some improvements. METHODS: Three batches I. indigotica were collected and prepared into decoction pieces according to the processing method of I. indigotica in pharmacopoeia. TLC identification of (R,S)-goitrin in I. indigotica decoction piece and medicinal material were conducted according to identification method (3) in pharmacopeia (80% ethanol as solvent for sample treatment, ultrasound extraction); the rationality of pharmacopoeia method was investigated. Then the method was improved by changing the extraction solvent and pretreatment method (method one: using water as solvent, ultrasound extraction; method two: soaking in water for 1 h, then adding into methanol, ultrasound extraction; method three: the sample was wetted and then dried, using 80% methanol as solvent, ultrasound extraction) of samples, and the optimal method was verified. According to the optimal method, the TLC identification of (R,S)-goitrin was detected by using chromatographic plates from different manufacturers, under the conditions of low temperature and low humidity (7 ℃, relative humidity 48%) and high temperature and high humidity (35 ℃, relative humidity 75%) respectively,to investigate the durability of the method. RESULTS: According to the method of pharmacopeia, in the chromatograms of decoction pieces, the same color spots appeared at the corresponding chromatographic positions of reference substance, but no corresponding spots appeared in the medicinal material chromatograms. After the samples were treated by three improvement methods, in medicinal material chromatograms, the same color spots appeared in the corresponding chromatographic positions of reference substances. There were single chromatographic spot after medicinal materials were treated with method one, and there were more spots after medicinal materials were treated with method two and three, and method two consumed less time than method three. The results of validation tests and method durability tests showed that after the treatment of I. indigotica and its decoction pieces according to method two, the same color spots appeared in the corresponding positions of the decoction pieces and the medicinal materials chromatograms as those of the control. CONCLUSIONS: The improved TLC identification method is effective, the chromatographic spots are clear, and the repeatability is good.
