OBJECTIVE: To analyze the subcellular localization of GTPase of immunity-associated protein 2 (GIMAP2) for the further functional study. METHODS: In the study, we first obtained the protein sequences of GTPase of immunity-associated protein 2 (GIMAP2) from National Center for Biotechnology Information (NCBI) database, and then performed a prediction analysis of its transmembrane structure, nuclear localization signal (NLS), nuclear export signal (NES) and subcellular localization through bioinformatics online tools. GIMAP2 gene amplified by PCR was inserted into the expression vector pQCXIP-mCherry-N1 and positive clones were selected by ampicillin resistance. After using methods to extract and purify, the sequenced recombinant plasmid pQCXIP-GIMAP2-mCherry, together with the retroviral packaging plasmids VSVG and Gag/pol, was transferred into HEK293FT cells by liposomes for virus packaging. The virus supernatant was collected 48 h after transfection and directly infected the human breast cancer cell line MDA-MB-436. Immunofluorescence staining was constructed to detect the localization of endogenous and exogenous GIMAP2 in MDA-MB-436 cells. Meanwhile, green fluorescent chemical dyes were used to label mitochondria, endoplasmic reticulum, and lipid droplets in living MDA-MB-436 cells stably expressing the GIMAP2-mCherry fusion protein. Images for the three dye-labeled organelles and GIMAP2-mCherry fusion protein were captured by super-resolution microscope N-SIM. RESULTS: Bioinformatics analysis data showed that GIMAP2 protein composed of 337 amino acids might contain two transmembrane helix (TM) structures at the carboxyl terminus, of which TMs were estimated to contain 40-41 expected amino acids, followed by the residual protein structures toward the cytoplasmic side. NES was located at the 279-281 amino acids of the carboxyl terminus whereas NLS was not found. GIMAP2 might locate in the lumen of the endoplasmic reticulum. Sequencing results indicated that the expression vector pQCXIP-GIMAP2-mCherry was successfully constructed. Fluorescent staining confirmed that GIMAP2-mCherry fusion protein, co-localized well with endogenous GIMAP2, expressed successfully in the endoplasmic reticulum and on the surface of lipid droplets in MDA-MB-436 cells. CONCLUSION GIMAP2 localizes in the endoplasmic reticulum and on the surface of LDs, suggesting potential involvement of GIMAP2 in lipid metabolism.

Objective To explore the effect of meteorological factors on the incidence of hand foot and mouth disease (HFMD) in Jiangyin City. Methods The distributed lag non-linear model (DLNM) was used to estimate the delayed and cumulative effects of meteorological factors on incidence of HFMD in Jiangyin from 2012 to 2017. Results A total of 21 791 HFMD cases were reported in Jiangyin City during 2012-2017. We observed significant correlations between the daily incidence of HFMD and daily mean temperature (rs=0.402, P<0.001), daily mean pressure (rs=-0.453, P<0.001), and daily mean relative humidity (rs=0.075, P<0.001), respectively. It was indicated that the maximum cumulative effect of daily mean temperature on the incidence of HFMD was 11 ℃ (RR=1.473, 95% CI: 1.99-1.974), and the impact on the onset of HFMD was acute and hightest at the first day (RR=1.090, 95% CI: 1.045-1.136). The cumulative effect on incidence of HFMD was highest at 85% daily relative humidity (RR=1.346, 95% CI: 1.154-1.571), and the impact on HFMD peaked on the 6th day (RR=1.023，95% CI: 1.015-1.031); The maximum cumulative effect of daily mean pressure with the incidence of HFMD was 1010.0 hpa (RR=1.221, 95% CI: 1.020-1.463), but no lag effect was observed at this level. Conclusions Meteorological factors have significant impact on the incidence of HFMD in Jiangyin City, and the effects of temperature and humidity are lagged.

BACKGROUND: iRegene collagen sponge exhibits stable physical and chemical properties, and has passed the test by the State Food and Drug Administration of China. OBJECTIVE: To study the hemostatic effect and the biocompatibility of the iRegene collagen sponge on a liver wound by means of rat models. METHODS: Liver trauma bleeding models were made in 21 Sprague-Dawley rats. These model rats were randomized into three groups (n=7 per group): experimental group with implantation and external application of iRegene collagen sponge; positive control group with implantation of medical collagen sponge and external application of iRegene collagen sponge; blank control group with external application of medical gauze. The bleeding time and amount on the liver wounds were observed. Histological observation on the liver wound was performed at 7, 14, 28 days after intervention. RESULTS AND CONCLUSION: The bleeding time was shorter in the experimental group than the positive control group (P ≤ 0.05). Beyond that, there was no difference in the bleeding amount and time among the three groups. Histological findings on the liver wound showed that the iRegene collagen sponge in the experimental group was completely wrapped with fibrous connective tissues and began to degrade at 7 days after intervention, the Inflammatory cell infiltration mainly occurred in neutrophils, and new capillaries were observed in peripheral connective tissues; at 14 days after intervention, the fibrous connective tissues became remarkably thickened, the number of neurophils was reduced, and the number of macrophages was increased; at 28 days after intervention, the iRegene collagen sponge degraded completely, most of the liver tissues recovered, and there were macrophages, monocytes, fibroblasts and capillaries in the inflammatory connective tissues adjacent to a part of liver tissues. Similar findings were observed in the positive control group. In the blank control group, there were obvious connective tissues on the wound and red blood cells in the liver sinus, and occasionally liver tissue bleeding and vacuolar degeneration were visible; at 28 days after intervention, there were thickened connective tissues on the wound, red blood cells in the liver sinus and reversed hepatic stellate cells. To conclude, the iRegene collagen sponge possesses effective hemostatic effects on liver wounds and shows good histocompatibility.

Aconite has the efficacy of reviving yang for resuscitation, dispelling cold and relieving pain, which is widely used in clinic, and shows unique efficacy in treating severe diseases. However, aconite has great toxicity, with obvious cardio-toxicity and neurotoxicity. Its toxicological mechanism main shows in the effect on voltage-dependent sodium channels, release of neurotransmitters and changes in receptors, promotion of lipid peroxidation and cell apoptosis in heart, liver and other tissues. Aconite works to reduce toxicity mainly through compatibility and processing. Besides traditional processing methods, many new modern processing techniques could also help achieve the objectives of detoxification and efficacy enhancement. In order to further develop the medicinal value of aconite and reduce its side effect in clinical application, this article gives comprehensive comments on aconite's toxicity characteristics, mechanism and detoxification methods on the basis of relevant reports for aconite's toxicity and the author's experimental studies.

OBJECTIVETo analyze the etiological and epidemiological characteristics of hand-foot-and-mouth disease (HFMD) seen in Jiangsu province from 2008 to 2010, and provide evidence for its prevention and control.

METHODSBased on the requirement of supervision program of HFMD, surveillance and report were done according to National Disease Supervision Information Management System. Descriptive epidemiological method, performed between 2008 and 2010, was used to analyze the time, region and population distribution and results of etiologic analysis of HFMD. Nucleic acid of enterovirus (EV) genome was detected by real-time RT-PCR.

RESULTSThe average incidence rate of HFMD was 86.70 per million between 2008 and 2010, the peak incidence occurred in April to July. There were significant differences among the incidence in different districts (P<0.05), and the highest incidence was seen in the densely inhabited southern areas of Jiangsu province. Most of the cases were infants and children aged less than 5 years. The number of male cases (2008: 17,008, 2009: 48 768, 2010: 50,231) was much larger than that of the female cases 2008: 9662, 2009: 29 151, 2010: 30,655. The HFMD cases with mild symptoms were caused mainly by enterovirus 71 (EV71) and coxsackievirus A16 (Cox A16) and there was difference among different years. The severe HFMD cases and deaths were mainly caused by EV71 infection.

CONCLUSIONSThe epidemiologic characteristics of HFMD in Jiangsu province from 2008 to 2010 had close relationship with season, population and region. The mild cases of HFMD were mainly infected with EV71 and Cox A16. However, EV71 illness seemed to be more severe and had significantly greater frequency of serious complications and fatality than the illness caused by Cox A16.

Objective To study the source of infection,the scope of epidemic and control measures in an outbreak involving students having symptoms as fever,dizziness,headache,vomiting and nausea.Methods The suspected-case was defined as fever (armpit temperature ≥37 ℃) and with one or more of the following symptoms:dizziness,headache,vomiting and nausea,among students and teachers at school from Mar 1,2012.Confirmed-case was among suspected case accompanied by both throat and rectal swabs enterovirus positive by RT-PCR.All the cases were collected through checking the medical records from 4 hospitals as well as through the absence records of students and teachers,from Mar 1,2012.We conducted a case-control study with ratio of 1 ∶ 2 and data on the exposures to water among students and teachers was collected prior to the illness.27 cases' throat and rectal swabs were collected and analyzed by RT-PCR and PCR sequence methods.2 warm-water samples were collected for testing the counts on total bacteria and E.coli.Results 103 students' cases were identified in school L,with the attack rate as 4.6％ (103/2255).Students from Grade three had the high attack rate as 18.1％ (72/397) and 77.7％ (80/103) of the cases located in the building with ' multiple-functions'.Epidemic curve of the outbreak showed a pattern with continuous common source of infection.It seemed that the exposure to warm-water appeared to be the major risk factor (OR =18.3,95％CI:2.0-169.5) together with the intake of un-boiled water (OR =15.5,95 ％CI:1.7-141.8).Specimens from 27 students (81.5％,22/27) were identified enterovirus positive by RT-PCR,and 7 of the 9 students were confirmed carrying Echo 30.Bacteria and coli were negative from the 2 warm-water samples.Conclusion This viral meningitis-outbreak was caused by Echo 30,with drinking water as the major risk factor.

OBJECTIVEThis research aimed to explore the application of ARIMA model of time series analysis in predicting influenza incidence and early warning in Jiangsu province and to provide scientific evidence for the prevention and control of influenza epidemic.

METHODSThe database was created based on the data collected from monitoring sites in Jiangsu province from October 2005 to February 2010. The ARIMA model was constructed based on the number of weekly influenza-like illness (ILI) cases. Then the achieved ARIMA model was used to predict the number of influenza-like illness cases of March and April in 2010.

RESULTSThe ARIMA model of the influenza-like illness cases was (1 + 0.785B(2))(1-B) ln X(t) = (1 + 0.622B(2))ε(t). Here B stands for back shift operator, t stands for time, X(t) stands for the number of weekly ILI cases and ε(t) stands for random error. The residual error with 16 lags was white noise and the Ljung-Box test statistic for the model was 5.087, giving a P-value of 0.995. The model fitted the data well. True values of influenza-like illness cases from March 2010 to April 2010 were within 95%CI of predicted values obtained from present model.

CONCLUSIONThe ARIMA model fits the trend of influenza-like illness in Jiangsu province.
