Objective To evaluate the effect of a new schistosomiasis control strategy based on the infection source control in four-lake regions of Hubei Province. Methods The new strategy based on the infection source control included the safe water sup-ply,feces harmless treatment,replacing cattle with machine,captive livestock,chemotherapy,Oncomelania hupensis snail con-trol in susceptible areas,hardening ditches,etc,and the new control strategy was implemented for 7 years in 9 counties(cities or districts)of the four-lake regions. The schistosomiasis situations were investigated before and after the intervention of the new strat-egy. Results The coverage rates of feces harmless toilets(three format toilets),biogas digesters,and safe water supply were 42.00%,23.16% and 93.76%,respectively. The number of ditch hardening was 1 960;the area of eliminating snails was 1 378.42 hm2;the number of persons who received the health education was 3 524 818 accounting for 92.17%of the total popula-tion;the number of person-time of taking active protection measures was 516 636 963. The average annual decline rates of schisto-some infection were 24.42%and 38.38%in residents and cattle,respectively. The endemic villages decreased by 4.77%,the vil-lages with snails decreased by 7.05%,and the villages with snails accounted between 63.19%and 66.21%of the total endemic vil-lages. The area with snails decreased by 90.35%,and the advance schistosomiasis patients decreased by 5.55%,and the fatality rate of advanced schistosomiasis patients decreased by 1.24%. No acute schistosomiasis patients occurred. Type One and Two en-demic(heavy endemic)villages decreased to zero;Type Three endemic(moderate endemic)villages decreased by 10.22%;but Type Four endemic(mild endemic)villages increased by 66.38%;and Type Five endemic(no endemic for 5 years)villages de-creased by 0.22%. The standards of schistosomiasis transmission controlled have achieved on schedule. Conclusion The imple-mentation of the new schistosomiasis control strategy based on the infection source control in four-lake regions of Hubei Province can effectively control schistosomiasis.

Alcoholic liver disease ( ALD ) , a chronic progres-sive disease, threatens human health seriously. An increasing number of studies have shown that gut flora dysbiosis plays an important role in the development of ALD. Intestinal microbiota maintains a steady state under normal conditions, regulating gut flora normal physiological function. However, chronic alcohol consumption produces intestinal bacteria overgrowth and dysbio-sis, including the alteration of the composition of intestinal mi-croflora, the increment of gut permeability and bacterial translo-cation. Subsequently, the host immune is activated, promoting the production of inflammatory cytokines in liver, which plays a central role in the development of ALD. Notably, the supple-ment of prebiotics or probiotics reverses the intestinal flora disor-der,ameliorating the clinical symptoms effectively in ALD pa-tients. The evidence impies that the modulation of dysbiosis may be effective in the prevention and treatment of ALD. This review summarizes the research progress on the mechanism of the devel-opment of dysbiosis-mediated ALD, to provide a theoretical basis for the research on intestinal flora and ALD.

Objective To explore the characteristic and clinical value of Somatosensory Evoked Potential SEP and event?related potential P300 in patients with Juvenile Myoclonic Epilepsy (JME), trying to provide neuroelectrophysiological evidence for the pathogenesis, diagnosis and antiepileptic drug efficacy of this disease . Methods 28 patients with JME and 30 healthy controls were enrolled in the research. They were applied the SEP and P300 before and after one year treatment. Results (1) The amplitude of SEP in patients with JME was significantly higher than those in the control group(P=0.000), the abnormal rate was 75%(21/28), while the latency of SEP was no significant difference (P>0.05); The latency of P300 in patients with JME was significantly longer (P = 0.000), 2 out of 28 cases were poorly differentiated, 9 cases were longer (11/28, 39%), while the P300 amplitude was no significant difference(P=0.110). (2) After treatment, the amplitude of SEP was significantly lower (P<0.05), the latency of P300 was significantly shorter (P=0.001). (3) The amplitude of SEP had a positively linear relationship with the latency of P300 (r = 0.818, P = 0.000). Conclusions The SEP amplitude was significantly higher in patients with JME, often accompanied by a huge SEP, so SEP can provide electrophysiological evidence for the pathogenesis and diagnosis of this disease.And P300 may give a chance to find the subclinical cognitive abnormalities and to intervent it early. The SEP had a positively linear relationship with the P300, simultaneously dynamic monitoring the change of SEP amplitude and P300 latency may become an objective evaluation for the antiepileptic drug efficacy.

Objective To explore a simpler, more economic and reproducible method to reproduce a model of high oxygen induced acute lung injury (HALI) in rats. Methods An animal feeding box equipped with a controllable high oxygen was designed. 100 Sprague-Dawley (SD) rats were divided into normal control group and HALI group by random number table method, with 50 rats in each group. Each group was randomly subdivided into five subgroups according to the duration of exposure to high oxygen, namely 0, 24, 48, 72 and 96-hour subgroups, with 10 rats in each subgroup. The rats in normal control group were kept in cages with ambient air, and the rats in HALI group were kept in an oxygen tank in which the oxygen concentration was higher than 90% volume ratio, with the temperature maintained at 25-27 ℃, humidity of 50%-70%, and CO2 concentration < 0.5% for 23.5 hours every day. The arterial blood of rats was collected for analysis of blood gas at all time points, and the oxygenation index (OI) and respiratory index (RI) were calculated. Then the rats were sacrificed and the right lung was harvested, which was sectioned and stained with hematoxylin and eosin (HE). The changes in histopathology were observed with light microscopy, and pathological score was recorded. The left lung was harvested for the measurement of the wet/dry weight ratio (W/D). Results With the prolongation of high oxygen exposure time, the degree of lung injury in HALI group was gradually increased, and the degree of derangement of alveolar structure appeared in an increasing degree, with destruction of the alveolar wall, widening of alveolar space, and appearance of edema, and inflammatory cell infiltration. A small quantity of red blood cells exudation could be found in some rats. The pathologic changes were most obvious at 48-72 hours after exposure. With the prolongation of high oxygen exposure time (0, 24, 48, 72, 96 hours), the OI (mmHg, 1 mmHg = 0.133 kPa) in HALI group was gradually decreased (446.67±29.93, 306.19±37.23, 269.70±29.00, 253.81±43.40 and 245.58±35.25), RI, pathological score of lung tissue and W/D ratio were gradually increased [RI: 0.25±0.04, 0.31±0.06, 0.38±0.06, 0.46±0.07 and 0.44±0.03; pathological score of lung tissue: 0.00±0.00, 0.90±0.74, 2.90±1.20, 4.70±1.57 and 4.80±1.23; lung W/D ratio: 3.84±0.61, 4.14±0.46, 4.56±0.34, 5.32±0.27 and 5.18±0.25]. Statistically significant differences were found in 72-hour group as compared with that of other groups (all P < 0.05), while no significant difference was found between 96 hours and 72 hours groups (all P > 0.05). There were significant differences in changes between 24, 48, 72, and 96 hours as compared with those of the normal control group: OI (mmHg): 24 h 306.19±37.23 vs. 435.65±25.34 and 96 h 245.58±35.25 vs. 465.42±24.75; RI: 24 h 0.31±0.06 vs. 0.24±0.04 and 96 h 0.44±0.03 vs. 0.24±0.06. The same as true in pathological scores of lung tissue: 24 h 0.90±0.74 vs. 0.00±0.00 and 96 h 4.80±1.23 vs. 0.00±0.00; lung W/D ratio: 24 h 4.14±0.46 vs. 3.79±0.44 and 96 h 5.18±0.25 vs. 4.12±0.91, all P < 0.05. Conclusions A self-designed high oxygen box is simple, easy to operate and reproduction of HALI model can be attained. Sustained exposure to high concentrations of oxygen (≥ 90%) for 24 hours can replicate the HALI model successfully, and the most serious injury appears at 48-72 hours after exposure.

Objective To explore the correlation between TOP2A gene expression and TCM constitutional types of patients with triple-negative breast cancer.Methods The questionnaire for constitution of Chinese medicine was used to identify the TCM constitutional types of 71 patients with triple-negative breast cancer and TOP2A gene alterations were quantified by real-time PCR. 2-ΔΔCt was used to analyze the expressions of each group. SPSS17.0 was employed to analyze the correlation between TOP2A gene amplification and TCM constitutional types.Results Totally 71 patients were divided into general type (0 case), Qi deficiency type (18 cases), Yang deficiency type (10 cases), Yin deficiency type (12 cases), Qi stagnancy type (7 cases), blood stasis type (10 cases), phlegm wet calculus type (8 cases), damp-heat type (6 cases), and special type (0 case). All of them were biased constitutional types, of which Qi deficiency constitution (25.35%), Yin deficiency constitution (16.90%), blood stasis constitution (14.08%) took the majority. TOP2A gene amplification was negative correlated with each constitutional type (P<0.05).Conclusion Biased constitutional types were the main types of TCM constitutional type of patients with triple-negative breast cancer. The main three biased constitutional types of triple-negative breast cancer were Qi deficiency constitution, Yin deficiency constitution and blood stasis constitution. TOP2A gene expression in patients with triple-negative breast cancer was normal or less expressed, which predicted low chemotherapy sensitivity and poor prognosis.
