In combination with the experience in teaching practice,we discuss medical lit-erary teaching reform,method and the significance and sparkplug exhibiting the knowledge forming process,cultivate managing the information ability,inspire creative interest,and form the style of study as "to study the phenomena of nature in order to acquire knowledge"and"reasonable doubt".

Objective To explore the effect of Buyang Huanwu decoction(BYHWD)on protein kinase B1 (AKT1)and c-Jun amino terminal kinase 1/2(JNK1/2)in rats after focal cerebral ischemia. Methods According to the random number table method,48 Sprague-Dawley(SD)rats were randomly allocated to four groups:normal control group,sham-operated group,model group,traditional BYHWD group(each n=12). The rat model of right focal cerebral ischemia was established by the method of middle cerebral artery occlusion(MCAO). The rats in BYHWD group were ingested with the decoction of BYHWD 14.2 g/kg after 2 hours of the operation(the main ingredients of BYHWD including astragalus mongholicus 120 g,Chinese angelica 6 g,radix paeoniae rubra 4.5 g, rhizoma ligustici wallichii 3 g,safflower 3 g,peach kernel 3 g,earthworm 3 g),once a day for 7 days. Other groups of animals were given the same amount of normal saline orally. After operation,on the 7th day,the animals were killed,and their brains were taken out. The reverse transcription-polymerase chain reaction(RT-PCR)assay was used to detect AKT1 mRNA expression,and immunohistochemical method was applied to measure JNK1/2 protein expression. Results Compared with normal control and sham-operated groups,the level of AKT1 mRNA expression〔absorbance(A)〕was decreased obviously(0.48±0.08 vs. 0.63±0.11,0.61±0.09,both P<0.05),and the number of JNK1/2 positive cells(cell/mm2)was increased significantly(34.13±4.57 vs. 16.15±1.09,16.23±2.05,both P<0.05)in model group;compared with model group,the AKT1 mRNA expression in brain tissue(0.93±0.11)and the number of JNK1/2 positive cells(45.04±5.68)was increased significantly in BYHWD group,the differences being statistically significant(P<0.05 or P<0.01). Conclusion BYHWD can up-regulate expressions of AKT1 mRNA and JNK1/2 positive cells in ischemic brain tissue that is one of the mechanisms in the protection of brain.

Objective To understand the current distribution and characteristics of advanced schistosomiasis patients who accepted medical assistance in Hunan Province in 2015,so as to provide the evidence for perfecting the policy and measures of the medical assistance to advanced schistosomiasis patients. Methods The patients who had been diagnosed as advanced schis-tosomiasis were verified and confirmed according to the standard of the medical assistance to advanced schistosomiasis patients in Hunan Province in 2015. The epidemiological survey was conducted to investigate the demographic characteristics,history of diagnosis and treatment,and medical assistance to these persons. Results There were 3850 advanced schistosomiasis patients who accepted the medical assistance in Hunan Province in 2015,and among them,2664 patients were male(69.19%),and 1186 were female(30.81%). Most of them(92.82%)came from the main schistosomiasis endemic areas,such as Yueyang, Changde and Yiyang. There were 2369 cases of ascites(61.53%),1466 cases of splenomegaly(38.08%),15 cases of colon proliferation and dwarf(0.39%). The mean age of advanced schistosomiasis patients who accepted the medical assistance was (62.94 ± 11.67)years old,with 64.31% of them being more than 60 years old. The age of initial diagnosis of advanced schistoso-miasis was(53.85 ± 21.32)years old,and it was concentrated in 40-60 years old(68.57%). The mean duration of advanced schistosomiasis was(9.58 ± 10.06)years,and it was mainly distributed in 10 years(75.95%). The mean duration from initial diagnosis of schistosomiasis to advanced schistosomiasis was(22.33 ± 14.20)years. The priority of the medical assistance to ad-vanced schistosomiasis patients was given to the county hospitals(76.57%);and the effective rate of assistance was 94.46%. To-tally 86.57% of the patients with advanced schistosomiasis got the medical insurance(rural cooperative medical care,urban medical care,etc.). Conclusions The burden of the medical assistance to advanced schistosomiasis patients is still heavy be-cause of many patients and low cure rate in Hunan Province. The ascites patients and high age patients should be the important objects of the medical assistance.
