Oncomelania hupensis is the only intermediate host of Schistosoma japonicum, and O. hupensis control is an important measure for schistosomiasis control. With the progress of national schistosomiasis control program, the prevalence of schistosomiasis is low in China; however, there are still multiple challenges for O. hupensis breeding and schistosomiasis transmission risk. Considering the target of the national schistosomiasis elimination program and environmental protection in the new era, the introduction of precision identification, precision interventions and precision assessment into O. hupensis control may facilitate the progress towards elimination of schistosomiasis in China.

Bioinformatics screening and analysis of key differentially expressed genes characteristics in nonalcoholic fatty liver disease / 中华肝脏病杂志

Objective: To screen and analyze the key differentially expressed genes characteristics in nonalcoholic fatty liver disease (NAFLD) with bioinformatics method. Methods: NAFLD-related expression matrix GSE89632 was downloaded from the GEO database. Limma package was used to screen differentially expressed genes (DEGs) in healthy, steatosis (SS), and nonalcoholic steatohepatitis (NASH) samples. WGCNA was used to analyze the output gene module. The intersection of module genes and differential genes was used to determine the differential genes characteristic, and then GO function and KEGG signaling pathway enrichment analysis were performed. The protein-protein interaction network (PPI) was constructed using the online website STRING and Cytoscape software, and the key (Hub) genes were screened. Finally, R software was used to analyze the receiver operating characteristic curve (ROC) of the Hub gene. Results: 92 differentially expressed genes characteristic were obtained through screening, which were mainly enriched in inflammatory response-related functions of "lipopolysaccharide response and molecular response of bacterial origin", as well as cancer signaling pathways of "proteoglycan in cancer" and "T-cell leukemia virus infection-related". 10 hub genes (FOS, CXCL8, SERPINE1, CYR61, THBS1, FOSL1, CCL2, MYC, SOCS3 and ATF3) had good diagnostic value. Conclusion: The differentially expressed hub genes among the 10 NAFLD disease-related characteristics obtained with bioinformatics analysis may become a diagnostic and prognostic marker and potential therapeutic target for NAFLD. However, further basic and clinical studies are needed to validate.

Discussion of novel mode of acupuncture and moxibustion based on identifying the acupoint sensitization / 中国针灸

On the base of the paradigms of clinical studies on modern moxibustion by identifying the acupoint sensitization, the records of ancient literature in successive dynasties were collected on "identifying the sensitization" of acupoints in acupuncture. In association with acupoint detection of acupuncture recorded in current textbooks, a novel concept, "exerting acupuncture by identifying the acupoint sensitization" is proposed. Acupoint sensitization is the common initial link of effect achieved by both acupuncture and moxibustion. Hence, on the basis of the routine acupoint selection by differentiating syndrome, the state of acupoint must be considerably emphasized in either acupuncture or moxibustion. The clinical curative effect may be improved by selecting the sensitized points and identifying sensitization. This novel mode of diagnosis and treatment focuses on identifying acupoint sensitization by unifying acupuncture with moxibustion and in coincidence with the modern clinical characteristics of either acupuncture or moxibustion.

Angiotensin Ⅱ receptor antagonist EMA401 used for sciatic nerve constriction-induced neuropathic pain in rats: behavior assessment and anaIgesic mechanisms / 中国组织工程研究

BACKGROUND: Chronic pain is characterized as high morbidity, long course and poor curative efficacy, and the underlying mechanism still remains unclear. The research on analgesics and analgesic mechanisms is an issue of concern. OBJECTIVE: To explore the effect of angiotensin Ⅱ receptor antagonists EMA401 on the mechanical withdrawal threshold in a rat model of sciatic nerve constriction-induced neuropathic pain and the underlying mechanisms. METHODS: Sprague-Dawley rats were randomized into five groups: the rat sciatic nerve was exposed without ligation (sham group), and NaCl solution was given via gastric lavage;the model of sciatic nerve constriction was established in the remaining rats,followed by treatment with 2,5 and 10 mg/kg EMA401,and NaCl solutions(model group)via gastric lavage,respectively.As a behavioral indicator,mechanical withdrawal threshold was detected at 1 preoperative day, 3, 7 and 14 postoperative days. Subsequently, the spinal dorsal root ganglion was removed, and the expression levels of glial fibrillary acidic protein, brain-derived neurotrophic factor and activating transcription factor 3 were detected by western blot assay. RESULTS AND CONCLUSION: Compared with the model group, EMA401 significantly improved the mechanical withdrawal threshold of the rats with sciatic nerve constriction (P < 0.05). Moreover, EMA401 significantly upregulated the expression levels of glial fibrillary acidic protein, brain-derived neurotrophic factor and activating transcription factor 3 in the dorsal root ganglion (P < 0.05); the expression levels in the 5 and 10 mg/kg EMA401 groups were significantly lower than those in the 2 mg/kg EMA401 group at 3, 7 and 14 days postoperatively (P < 0.05). These findings implicate that EMA401 exerts obvious analgesic effect on the rat model of sciatic nerve constriction,which may be via inhibiting astrocyte activation in the spinal dorsal root ganglion, downregulating the expression level of brain-derived neurotrophic factor, and further inhibiting the dorsal root ganglion neuron activation that appears with an increase in activated transcription factor 3 expression.

<p><b>OBJECTIVE</b>To analyze the clinical features idiopathic ventricular tachycardia (IVT) and evaluate the effect of radiofrequency ablation therapy for their management.</p><p><b>METHODS</b>An retrospective analysis was conducted in 165 IVT patients who received radiofrequency ablation therapy. IVT was classified into 3 types according to the site of origin, namely the right ventricular outflow tract (RVOT-IVT, 86 cases), left ventricular septum (LV-IVT, 75 cases), and left Valsalva sinus (4 cases).</p><p><b>RESULTS AND CONCLUSION</b>RVOT-IVT was more frequent in female patients than in male patients (60 vs 26, M/F ratio of 0.43). In LV-IVT, male patients prevailed (54 vs 21, M/F ratio of 2.57), suggesting a gender difference in the incidence of IVT. IVT occurred mainly in young and middle-age patients. Most RVOT-IVT occurred in the third to fourth decade of life (mean 36-/+12 years), and LV-IVT occurred at a younger age than did RVOT-IVT (mean 26-/+15 years, P<0.01). Twelve-lead ECGs revealed left bundle branch block morphology in RVOT-IVT, and most of them presented with frequent premature ventricular contraction and/or non-sustained ventricular tachycardia. All the RVOT-IVT patients were successfully ablated by radiofrequency energy in pace mapping. LV-IVT patients with right bundle branch block morphology presented sustained ventricular tachycardia for most of the time, and 97% of the patients were successfully managed with radiofrequency ablation in activation mapping. Four IVT patients were characterized by atypical bundle branch block, an inferior axis, and an R/S ratio >1 in lead V3 or V2, and their tachycardia was ablated successfully in the left sinus of Valsalva using pace mapping. Radiofrequency ablation is currently an effective procedure for IVT management.</p>
