Objective To assess the risk of secondary transmission induced by imported malaria in Jiangxi Province，so as to provide the evidence for adjustment of malaria surveillance strategies in the key groups and areas. Methods The Delphi method was used to establish the secondary transmission risk indicator system and the weight of each index was obtained. The data of malaria prevalence，vector distribution and intervention capacity were collected in 100 counties of Jiangxi Province from 2012 to 2015. The transmission potential index（TPI），intervention capacity index（ICI），and malaria risk index（MRI）were calculated for each county. The risk map was drawn with GIS software. Results The top ten counties with highly potential risk indicators were Linchuan District（2.131），Xinzhou District（1.609），Jiujiang County（1.404），Zhanggong District（1.365）， Fengcheng City（1.225），Qingshanhu District（1.184），Yudu County（1.171），Dingnan County（1.018），Xunyang District（1.015）and Zhushan District（1.006）. The high risk areas were mainly distributed in the regions of the capitals of their prefectures and in counties with more floating population. Conclusions There are the risk of the secondary transmission induced by imported malaria in Jiangxi Province. The high risk of the secondary transmission is shown in the areas with more floating population and weaker intervention capacity.

OBJECTIVETo evaluate the clinical effects of single posterior debridement, bone grafting, internal fixation and local chemotherapy in treating thoracolumbar spinal tuberculosis.

METHODSFrom February 2009 to September 2012,11 patients with thoracolumbar spinal tuberculosis were treated by single posterior debridement, bone grafting, internal fixation and local chemotherapy. There were 7 males and 4 females, aged from 27 to 65 years old with an average of 53.7 years. The courses of disease was from 3 months to 2 years with the mean of 9 months. According to ASIA standard of spinal cord injury, 3 cases were grade C and 8 cases D. After treatment, clinical effects were evaluated by ASIA grade, visual analogue score (VAS) and Oswestry Disability Index (ODI); kyphosis Cobb angle change was observed by X-rays.

RESULTSEleven patients were followed up from 12 to 29 months with an average of 18 months. ASIA grade of spinal cord injury, 3 patients with grade C improved to grade D in 2 cases and grade E in 1 case 8 patients with grade D improved to grade E in 7 cases and unchanged in 1 case. VAS decreased from preoperative 6.10 ± 1.30 to 1.70 ± 0.80 at 3 d after operation (P < 0.05). ODI improved from preoperative (68.36 ± 10.41)% to (14.55 ± 8.99)% (P < 0.05) at 3 d after operation. Kyphotic Cobb angle was corrected from preoperative (22.64 ± 4.84)° to (4.27 ± 1.49)° (P < 0.05) on the 3rd day after operation, and angle loss was mild at final follow-up, there was no significant difference between postoperative at 3 d and final follow-up.

CONCLUSIONSingle posterior debridement, bone grafting, internal fixation and local chemotherapy for the treatment of thoracolumbar spinal tuberculosis can effectively remove the lesion, improve nerve function and correct deformity, has advantage of single incision, little trauma, and low recurrence rate. But it still need long-term and systemic treatment with anti-TB drugs.

It's difficult to diagnose precancerous lesion and early cancer for a long time, because both of them haven't typical morphological characteristics. As a novel diagnostic modality, fluorescence endoscopy can accurately reflect minimal changes in human's tissue, thus making a meaningful progress for cancer diagnosing. 200 patients were examined by fluorescence endoscopy to evaluate the diagnostic value. The overall accuracy, sensitivity and specificity for detecting malignant gastrointestinal tumor was 94.0%, 94.6% and 93.5%, respectively. Thus, fluorescence endoscopy can be used to diagnose malignant gastrointestinal tumors with high validity and reliability, and is advantageous over conventional white light endoscopy especially in detecting the atypical and suspicious lesions. Furthermore, fluorescence endoscopy can also guide target biopsy, is significant to improve the early cancer detection rate, has a broad development prospect.

This paper is aim to investigate the pharmacokinetics and absolute bioavailability of neoline in Beagle dogs, and provide a theoretical basis for further study. Ethyl acetate was used for liquid-liquid extracting after 10% ammonia alkalizing. The method of UPLC-Q-TOF-MS was established for the determination of neoline plasma concentrations. Beagle dogs were orally or intravenously administered with neoline for pharmacokinetic and absolute bioavailability study. Good linear relationship of neoline was found over the range of 0.1-4 mg x L(-1) (R2 = 0.9982) and 2-100 microg x L(-1) (R2 = 0.9945). Intra-and inter-day precision, expressed as the relativestandard (RSD) were less than 5.0%. Accuracy, expressed as the relative error (RE) was within 90.0%-115%. The recovery of neoline in dog plasma was more than 80%. After 6 mg x kg(-1) for ig and 1 mg x kg(-1) for iv administration of neoline, the main pharmacokinetic parameters were analyzed with Winnonlin software. t(1/2) were (313.88 +/- 63.18), (236.33 +/- 229.84) min, and AUC(0-infinity) were (58,027.40 +/- 14,132.69), (473,578.02 +/- 82,333.08) min x microg x L(-1) for ig and iv administration respectively. The absolute bioavail ability was (73.15 +/- 10.29) %. The method of UPLC-Q-TOF-MS described in the report was sensitive, reliable and specific, and suitable for pharmacokinetic study of neoline in Beagle dog. The high absolute bioavailability of neoline in dog suggested good absorption of neline which was worth of further investigation.

Oxidative stress could induce apoptosis and autophagy process simultaneously, but the role of autophagy is still not clear. Beclin 1, a key gene regulating the preautophagosome formation, is involved in the injury induced by oxidative stress. To observe the role of autophagy in H2O2-induced injury of U251 cells, the recombinant plasmid Psilencer3.1-siRNA-Beclin 1 was transfected into U251 cells by eukaryotic cell transfection technique. Plasmid vector and cell culture medium were used as negative and control groups respectively. The cells were collected 24 h later, and the cell total protein was extracted to detect Beclin 1, Bcl-2 and Bax protein expressions by Western blot. After the Beclin 1-siRNA cells were treated with 1 mmol/L H2O2, the autophagic vacuoles in the cells were stained with monodansylcadaverine (MDC), and the cell apoptotic ratio was determined with PI/Annexin V-FITC staining by flow cytometry analysis. The results showed that the synthetic siRNA decreased the expression of Beclin 1 protein significantly, but had no obvious effect on the levels of Bcl-2 and Bax protein expressions. Compared with those in the control group, the autophagic vacuoles, the level of LC3-II protein expression and the percentage of apoptotic cells increased (P < 0.05) in 1 mmol/L H2O2 group. In Beclin 1-siRNA + H2O2 group, autophagic vacuoles and the levels of LC3-II protein expression decreased obviously, the percentage of apoptotic cells increased significantly compared with that in 1 mmol/L H2O2 group (P < 0.05). H2O2 and autophagy inhibitor 3-methyladenine (3-MA) combination also increased the percentage of apoptotic cells obviously (P < 0.05). These results revealed that the transfection of Psilencer3.1-siRNA-Beclin 1 effectively inhibited the expression of Beclin 1 protein expression, degraded the autophagy level and increased the apoptotic rate in U251 cells under oxidative stress, which was coincident with the effect of autophagy inhibitor 3-MA. This study suggests that autophagy is a cell protective role in oxidative stress process, and the inhibition of autophagy may enhance apoptosis.
