Objective To observe the therapeutically effect of kangnao liquid on Pi3k mRNA and Aktm RNA ex-pressions in rats with focal cerebral ischemia-reperfusion (I/R) injury. Methods 180 male SD rats were randomly divided into 6 groups:sham operated group, model group, three kangnao liquid groups (high-dose, medium-dose and low-dose) and nimodipine group. Rats in kangnao liquid groups were administrated with kangnao liquid of 24 g/(kg · d), 12 g/(kg · d) and 6 g/(kg · d), orally once a day. Rats in nimodipine group were given nimodipine 1 mg/(kg · d). Rats in model group and sham group were treated with the same volume of distilled water for 7 days. The animal model of middle cerebral artery occlusion (MCAO) was established by a monofilament method from right internal carotid artery. The neurological evaluation was per-formed 24 h after reperfusion. The in situ hybridization was used to investigate the expression levels of Pi3k mRNA and Akt mRNA in rats on 12 h, 24 h, 48 h, 72 h and 168 h after ischemia for 2 h. Results Compared with model group, neurological functions were improved significantly in kangnao liquid groups. The expression levels of Pi3k mRNA and Akt mRNA were al-so significantly higher in kangnao liquid groups than those of model group. The expression levels of Pi3k mRNA and Akt mRNA were significantly higher in nimodipine group than those of model group, but which were lower compared with those of high-dose and medium-dose kangnao liquid groups. Conclusion Kangnao liquid can protect nerve cells by enhancing the expressions of Pi3k mRNA and Akt mRNA in rats with cerebral ischemia-reprefusion injury.

Objective To investigate the relationship between neurokinin B (NKB), endothelin-1 (ET-1) and the pathogenesis of hypertensive disorder complicating pregnancy (HDCP). Methods 22 HDCP, who received antenatal examination in the Department of Obstetrics and Gynecology of Union Hospital of Tongji Medical College in Huazhong University of Science and Technology from March to July in 2005, were selected for the study, including 12 gestational hypertension (gestational hypertension group) and 10 preeclampsia (preeclamptic group); 22 normal pregnant women in the same period were served as control. At different gestational weeks, maternal plasma levels of NKB and ET-1 in three groups were detected by enzyme-linked immunoassay technique, the expression and location of NKB in placenta were examined by immunohistochemical SP, and mRNA expressions of NKB and ET-1 in placenta were measured with RT-PCR method. Results (1) At 10 - 14, 20 - 24, and 30 - 34 gestational weeks, the plasma levels of NKB and ET-1 in preeclamptic group were ( 35. 6±5.2), ( 17. 9±4. 3), (39. 5±4. 3 ), (22. 7± 3.6), (47. 1±3. 3) and (27.5±3.5) μg/L, respectively; in the control group they were (22. 9±3. 3), (10.7±5.3), (30.2±3.4), (13.2±4.1), (34.6±4.3) and (16.6±4.8) μg/L, respectively. There was a significant difference between preeclamptic group and control group ( P < 0. 05), while there was no significant difference between gestational hypertension group and control group (P>0.05).(2) Immunohistochemical staining for NKB protein was observed in all groups and was located in the villous syncytintrophoblast and villous vascular endothelial cells as well as cytoplasm of stromal cells, mostly located in villous syncytiotrophoblast. The expressions of NKB in placenta of preeclamptic group (0.244±0.020) was significantly higher than that in control group (0. 160±0. 012), with a significant difference between the two groups (P<0.05 ). However, there was no significant difference between gestational hypertension group (0.162±0.019) and control group (P>0.05). (3) The transcription levels of the NKB mRNA (0. 97±0. 36) and ET-1 mRNA (0. 90±0. 36) in preeclamptic placentas were both significantly higher than those in control groups (0. 78±0. 54, 0. 65±0. 47, respectively ), with a significant difference between the two groups( P <0. 05 ). But there was no significant difference between gestational hypertension group (0. 80±0. 40, 0. 70±0. 32, respectively) and control group (P >0. 05). (4) There was an evident positive correlation between plasma NKB and ET-1 levels in preeclampsia ( r =0. 79, P < 0. 05 ). Conclusions The significantly increased maternal plasma levels of NKB and ET-1 of patients with preeclampsia occur at early pregnancy (10 -14 gestational weeks) before the onset of clinical symptoms. The change of maternal plasma levels of NKB and ET-1 is closely related to pathogenesis of HDCP.

This report presented the endemic status of schistosomiasis in the People’s Republic of China at a national level in 2015,and analyzed the data collected from the national schistosomiasis prevention and control system and 457 national schis?tosomiasis surveillance sites. Among the 12 provinces(municipality,autonomous region)endemic for schistosomiasis japonica in P. R. China,5 provinces(municipality,autonomous region),i.e.,Shanghai,Zhejiang,Fujian,Guangdong and Guangxi, had achieved transmission interruption,and 7 provinces of Sichuan,Yunnan,Jiangsu,Hubei,Anhui,Jiangxi and Hunan had achieved transmission control by the end of 2015. There were 453 endemic counties(city,district)covering 252 million peo?ple,specifically including 29 980 endemic villages of 68.61 million people at risk of infection. Among the 453 endemic counties (city,district),75.72%(343/453)and 24.28%(110/453)reached the criteria of transmission interruption and transmission control,respectively. By the end of 2015,it was estimated of 77 194 cases of schistosomiasis,which were decreased by 33.23%compared with 115 614 cases in 2014. No acute schistosomiasis cases were reported in 2015. There were 30 843 advanced schis?tosomiasis cases documented in 2015. A total of 8 736 036 individuals received schistosomiasis examinations and 3 606 individu?als were parasitologically diagnosed,which were decreased by 56.40%compared with 8 270 cases in 2014. An Oncomelania hu?pensis snail survey was performed in 19 965 endemic villages and the snails were found in 5 609 villages,accounting for 28.09%of total villages,with 31 newly detected villages with snails. The snail survey covered an area of 593 572.66 hm2 and snails were found in an area of 173 462.50 hm2,including a newly detected area of 666.04 hm2. No infected snails were found in 2015. A to?tal of 879 373 bovines were raised in the schistosomiasis endemic regions. Of them,526 062 bovines received stool examina?tions,resulting in 315 infected bovines. There were 170 438 schistosomiasis cases receiving drug treatment in 2015,with 2 449 696 individuals undergoing expanded chemotherapy. There were 318 bovines with schistosomiasis receiving drug treatment,with 483 213 bovines undergoing expanded chemotherapy. A total of 144 305.52 hm2 area was subject to snail control by using mollus?cicides,with an actual molluscicide?treated area of 69 221.57 hm2,and 4 572.06 hm2 snail habitats were treated by environmen?tal modification. Based on the data from the 457 national schistosomiasis surveillance sites,the mean Schistosoma japonicum in?fection rate was 0.05% and 0.04% in humans and bovines,respectively. No infected snails were found in all the surveillance sites. The results demonstrate a decline in the endemicity of schistosomiasis in P. R. China and the country reached the criteria of transmission control at the national level. However,the endemic situation of schistosomiasis is unstable in some regions with newly?reached transmission control,and further control and effective surveillance should be strengthened to consolidate the achievements and reduce the endemic situation of schistosomiasis in P. R. China.
