Currently, the herbal prescription therapy for corresponding constitutional diseases is a common constitution regulating method. This method has an obvious effect in treating and regulating constitution-related diseases. However, for people who do not have disease, they prefer to regulate constitution with dietary therapy. In this paper, the researchers came up with a design method of constitution regulating and healthcare foods based on medicinal property combination mode of clinical empirical formulas. With "Yupinfeng San", a common formula for Qi-insufficiency constitution and specific endowment constitution, as the example for constitution regulating and healthcare foods, the researchers proved the effectiveness and rationality of healthcare food schemes in terms of the efficacy of single herb and the modern pharmacological study.

OBJECTIVETo analyze the incidence rate, animal hosts, and human inapparent infection rate from surveillance data collected in Jiangsu province from 1996 to 2000 and the risk factors of hemorrhagic fever with renal syndrome (HFRS).
METHODSData on the incidence rate was collected from the whole province to describe the epidemiologic characteristics of HFRS. Data on the density of rats, proportion of rats with virus, index of rats with virus and the human inapparent infection rate were collected in special areas according to the standardised protocol in the project.
RESULTSThe incidence rate of HFRS reduced continuously in Jiangsu province, with a 42.17% reduction from 1996 to 2000. The ratio between the incidence rate of autumn-winter peak and spring peak had also reduced. The main host in spring was Rattus norvegicus (with a density of 3.07%), while that in autumn was Apodemus agrarius (with a density of 4.64%). The density of main hosts and mixed species of rats had all reduced during the five years of observation. The proportions of Rattus norvegicus, Apodemus agrarius, Mus musculus with virus were relatively high in spring and autumn. The index of Rattus norvegicus and Mus musculus with virus in spring were 0.025 5 and 0.028 4 respectively, while that of Apodemus agrarius with virus in autumn was 0.030 2. The average human inapparent infection rate was 4.73% in the five years.
CONCLUSIONThe incidence rate of HFRS in Jiangsu reduced significantly from 1996 to 2000, but the risk factors still widely existed. Suggesting that the surveillance program needs to be carried out steadily in Jiangsu.

Objective To find out the data sources of respiratory syndromes and their components from the outpatients of general hospitals and to describe the time distribution and mutual relations of different respiratory syndromes. Feasibility of respiratory syndromes used for early warning surveillance on respiratory infectious disease was also under research. Methods Retrospective investigation on Hospital Information System (HIS) was implemented in a general hospital in Guangzhou, 2005, and data of outpatients was collected and classified into different syndromes. The respiratory syndromes with its time distribution similar to influenza like illness (ILI),were selected, and cross-correlation analyses were conducted to inveshgate the feasibility of respiratory syndromes for early warning surveillance on respiratory infection diseases (influenza as an example). Results Primary sub-classification of respiratory syndromes in outpatient department would include upper respiratory infection(URI)(51.20%), trachitis/bronchitis (18.80%), asthma ( 17.52% ), etc. Pulmonary infection accounted for only 2.26%. Time distributions of URI, trachitis/bronchitis, pulmonary infection, cough and asthma in outpatient department, X-ray tests and pneumonia/acute respiratory distress syndromes (ARDSs) in outpatient X-ray room were similar, with two peaks observed. Cross-correlation functions were calculated with the data sets of 1st-28th week.The most significant correlation was detected between the time series of outpatient pulmonary infections and ILIs moved 4 weeks backward (r=0.739, P<0.01 ), and that was detected between URIs and ILIs moved 5 weeks backward (r=0.714, P<0.01 ). Correlation between X-ray tests,pneumonia/ARDSs in outpatient X-ray room and ILIs was the strongest when ILIs time series moved 1 week backward (r=0.858, P<0.001; r=0.821, P<0.001 ). Conclusion Outpatient data from HIS system in general hospital could be applied to syndromic surveillance on respiratory diseases. For early warning epidemics or outbreaks of influenza or other respiratory infectious diseases, data of outpatient pulmonary infection appeared to be the most feasible for its specificity and timeliness, followed by URI and cough. X-ray tests and pneumonia/ARDSs in outpatient X-ray findings were important supplementary to verify the respiratory disease epidemics or outbreaks for its good specificity, but with no advantage for early warning.

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.

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.
