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.

AIM: To evaluate the effect of the chosen incision on corneal astigmatism after implantable collamer lens ( ICL) surgery.
METHODS:The study included 195 eyes of 102 patients, and all eyes were randomly divided into two groups: the chosen incision group ( Group A, 97 eyes) and temporal corneal incision ( Group B, 98 eyes ) . Before the operation, and 1wk, 1mo and 3mo after the operation, each patient was examined with corneal topography to observe the changes of corneal astigmatism.
RESULTS: Preoperative corneal astigmatisms were (1-26±0. 35) D in group A and (1. 28±0. 38) D in group B, thus there was no statistically significant difference ( P>0-05). One week postoperatively, the astigmatism were (0.93±0.29)D in group A and (1.32±0.33)D in group B. One month postoperatively, the astigmatism were (0. 85±0.16)D in group A and (1.27±0.18)D in group B. Three months postoperatively, the astigmatism were ( 0. 80±0-13)D in group A and (1. 25±0. 20) D in group B. The differences between the two groups were statistically significant (P<0. 01).
CONCLUSION: The chosen incision can reduce postoperative astigmatism to a certain extent after ICL surgery.

Background Research showed that exposure of 530 nm monochromatic light can induce myopia in animal,and retinal Müller cells participate in the formation of myopia.However,the effect and mechanism of retinal Müller cells during the formation of monochromatic light induced-myopia is below understood.Objective This study was to investigate biologic characteristics of rat retina Müller cells and the expression of cell factors in Müller cells after being illuminated by the 530 nm monochromatic light,and discuss the role of the retina Müller cells in myopia induced by monochromatic light.Methods Immortalized rat retinal Müller cells were cultured with DMEM containing 10％ fetal bovine serum in a self-made cell incubator with monochromatic light by adjusting luminance of 530 nm LED source.The cells were exposed to 125,250 and 500 lx luminance respectively for 6,12 and 24 hours,and the cells without light-irradiation were used as control.The growth of the cells under the different light time and different illuminations was described by MTT as the absorbance at the wavelength 570 nm (A570),and cell cycle analysis of Müller cells was performed by flow cytometry 48 hours after cultured,and the expression of transforming growth factor-beta 1 (TGF-β1),tyrosine hydroxylase(TH),inducible nitric oxide synthase(iNOS) and basic fibroblast growth factor(bFGF)in the cells were detected by reverse transcription PCR(RT-PCR),respectively.Results The Müller cells were uniform in size with polygonal shape and defined edges.No statistically significant difference was found in the A570 value in the cells of the 125 lx and 250 lx illuminated groups compared with the control group in various time points(P＞0.05).However,significant lowing was seen in the A570 value in the cells of the 500 lx illuminating for 12 hours and 24 hours in comparison with the control group (P =0.013,0.001).Compared with the control group,the ratio of the number between G2 and G1 phase was not significantly declined in 125 lx,250 lx illuminating for 48 hours (P =0.073,0.330),and the ratio in the 500 lx illuminating group was significantly lower than those in the 250 lx illuminated group and the control group (P =0.028,0.038).RT-PCR revealed that the expression of TGF-β1 mRNA in the cells was higher in the 250 lx illuminated group than that of the 500 lx illuminated group (P=0.006).The expression of iNOS mRNA was gradually upregulated in the 250 lx illuminated group compared with the control group (P =0.001),but that in the 500 lx illuminated group was downregulated (P =0.000).The expression of bFGF mRNA was raised in the 125 lx and 250 lx groups but reduced in the 500 lx group when compared with the control group(P=0.002,0.000,0.005).Also,the expression of TH mRNA was significantly increased in the 250 lx group(P=0.000),but decreased in the 500 lx group(P=0.000,P=0.001).Conclusions The monochromatic light of 530 nm can inhibit the growth of rat Müller cells and downregulate the expression of myopia-related cell factors and therefore exert effect in the formation of myopia.

The tail suspension test (TST), forced swimming test (FST) and chronic unpredictable mild stress (CUMS) model were used to evaluate the anti-depressant effect of supercritical CO2 extract from Compound Chaigui Fang (FFCGF). A nuclear magnetic resonance (NMR)-based metabonomics combined with multivariate statistical analysis was performed to explore the mechanism of FFCGF. Rats were conducted by CUMS procedure for 28 days and drugs were administrated at the same time. The body weight, sucrose preference, crossings and rearings in open-field tests were evaluated and the urine was collected simultaneously. The metabonomic profiles of rats' urine were analyzed by NMR and potential biomarkers were searched by multivariate statistical analysis. The results showed that administration of FFCGF significantly decreasing the immobility time in FST and TST and improving rats' body weight, sucrose preference, crossings and rearings in CUMS, which were indication that the anti-depressant effect of FFCGF was abvious. Significant differences in the metabolic profile of the CUMS treated group and the control group were observed, which were consistent with the results of behavioral tests. Decreased levels of acetic acid, succinic acid, 2-oxidation glutaric acid and citric acid and increased glycine and pyruvic acid in urine were significantly affected by the CUMS procedure and the 6 biomarkers were reversed evidently after administration of FFCGF. These changes were suggestion that the anti-depressant mechanism of FFCGF was associated with energy metabolism, lipid metabolism and amino acid metabolism.

OBJECTIVEThe aim of this study was to investigate the value of free anterolateral thigh myocutaneous flap (ALTMF) and computed tomography angiography (CTA) for the reconstruction of mouth-floor defects after the resection of middle-late stage carcinoma of the mouth floor.

METHODSSixteen cases of middle-late stage carcinomas of the mouth floor underwent radical resection, and mouth-floor and tongue defects were reconstructed with ALTMF. CTA was applied to plan the lateral circumflex femoral artery (LCFA) and its perforating vessel, which was verified during the operation.

RESULTSThe position of the perforating vessel in the operation was fully consistent with that designed by the preoperative CTA. All 16 flaps completely survived. The appearance and function of all cases were both satisfactory. All donor sites were primarily closed and healed without functional morbidity. During the follow-up period of 6-36 months, 15 cases survived with acceptable aesthetic and functional results in mouth floor and tongue reconstruction, except for 1 case (T4N2M0) that died of metastasis carcinoma 10 months after operation.

CONCLUSIONCTA can accurately locate the LCFA and artery perforator. Preoperative perforator planning using CTA in ALTMF transplantation is a reliable and useful method thatresults in safe operation with optimal outcome. The ALTMF is an ideal choice for the reconstruction of soft tissue defects after the resection of middle-late staie carcinoma of the mouth floor

Heme oxygenase-1 (HO-1) is a cellular stress protein, and its expression plays an important regulatory role in a lot of physiological and pathological processes. Although the expression of HO-1 in most tissues of body is low, a number of clinical and pharmacological experiments have proved that many compounds can induce HO-1 expression. The increase of HO-1 expression is the result of regulating different signaling pathways and transcription factors, and this induction of HO-1 is suggested to be partially therapeutic efficacy of these compounds. This article summarizes some kinds of compounds in this field of research at home and abroad over the last 10 years, and provides a brief analysis of the mechanism.
