ABSTRACT
Zhangjiagang Hospital of Traditional Chinese Medicine, as a collaborative unit of the project, participated in the clinical consistency evaluation in project of TCM Practice guidelines for Prevention and Treatment of Biqiu (allergic rhinitis) organized by the State Administration of Traditional Chinese Medicine. The evaluation results showed that the guideline met the clinical practice requirements. This article summarized the clinical evaluation experience from the three aspects: The diagnosis in TCM and Western medicine is clear and definite, but the English translation needs to be considered; The definition of remission phase of Biqiu (allergic rhinitis) is difficult, to interfere by identifying the constitution is innovative; The advantages of "preventive treatment of diseases" in TCM should be fully played in role, improving the satisfaction of patients.
ABSTRACT
Objective To know the immunologic response at different periods with different hepatitis B vaccine(HepB)in infants.Methods From July 1 to December 31 in 2009,the local infants born from hepatitis B virus(HBV)surface antigen (HBsAg)negative mother in Ninghai were selected and received a 0.5 ml of 5 -μg HepB made by recombinant deoxyribonucleic acid (DNA)techniques in saccharomyces cerevisiae yeast (HepB -SCY)and those in Yuyao were selected and received a 0.5 ml of 10 -μg HepB made by recombinant DNA techniques in hansenula polymorpha yeast (HepB -HPY)with a 0 -1 -6 month schedule.The specimens of blood were collected at 7 months,12 months and 18 months after vaccination for testing antibody.Results At 7 months,12 months and 18 months after vaccination,the geometric mean concentration (GMC)of Anti -HBs in HepB -SCY group were 714.79 ±3.50 mIU /mL,259.89 ± 3.87 mIU /mL and 78.38 ±4.04 mIU /mL,respectively.While in HepB -HPY group were 2 420.76 ±3.51 mIU /mL, 703.55 ±3.46 mIU /mL and 171.32 ±3.76 mIU /mL,respectively.There was statistical significant difference of GMC between HepB -SCY group and HepB -HPY group(P <0.01).The percent of antibody <100 mIU /mL in HepB -SCY group were 6.39%,23.33% and 55.42%,and in HepB -HPY group,were 2.17%,5.17% and 31.95%,respectively. The difference between HepB -SCY group and HepB -HPY group had significantly statistical significance (P <0.01 ). Conclusion The immunologic response at different periods of HepB -HPY was better than that of HepB -SCY.

ABSTRACT
Objective To explore the economic burden of chronic hepatitis B -relevant diseases and to understand the factors associated with the economic burden. Methods Economic - related information was collected by questionnaire investigation in Ningbo City. Hospital records and hospitalization expenses were obtained when 630 patients discharged from hospital. Influencing factors of the economic burden were analyzed by stepwise multiple linear regressions. Results The average of the total cost for the diseases was 65 139. 51 Yuan. Direct medicinal and non-medical costs were 61 606. 78 Yuan and 3 532. 73 Yuan respectively. The total annual costs for primary carcinoma of the liver,chronic severe hepatitis B,Hepatitis cirrhosis and chronic hepatitis B were 123 571. 78 Yuan,93 278. 65 Yuan,82 467. 99 Yuan and 21 824. 31 Yuan respectively. The average ratio of direct medical to direct non-medical cost was 17. 44,in which primary carcinoma of the liver,hepatitis cirrhosis,chronic severe hepatitis B,chronic hepatitis B were 19. 17,15. 52,21. 62 and 17. 02 respectively. The total cost was 1. 75 times higher than annual income of individual,as well as 1. 02 times higher than household income. Occupation,complication,income,diagnosis results were the influencing factors for economic burden. Conclusion The economic burden of chronic hepatitis B-relevant diseases was enormous in Ningbo City. The cost of direct medical was larger than direct non -medical. Expenses increased dramatically as the disease progressed to more advanced stage.
ABSTRACT
<p><b>OBJECTIVE</b>To analyze the epidemiological characteristics of hand foot and mouth disease (HFMD) in Ningbo.</p><p><b>METHODS</b>A descriptive analysis was conducted through the surveillance data of HFMD in Ningbo, Zhejiang province, from 2008 to 2011. Genes on EV71 and Cox A16 were amplified with RT-PCT from the stool samples of HFMD patients. Sequences were analyzed by bioinformatics software.</p><p><b>RESULTS</b>37 524 cases of HFMD were reported from 2008 to 2011, including 196 severe cases and 12 deaths. The reported incidence was 145.26 per 100 000 and the case fatality was 0.03%. Cases in children aged 5 or younger accounted for 95.89%, and the scattered cases accounted for 64.10%. Xiangshan and Ninghai counties had the highest incidence rates in Ningbo. The peak of incidence was from April to July. The number of male patients was obviously higher than females. 2394 cases of HFMD were laboratory confirmed and EV71 with the predominant epidemic strain. Data from phylogenetic analysis revealed that EV71 isolated from HFMD patients in Ningbo belonged to C4a evolution branch of C4 sub-genotype, with several transmission chains. Cox A16 belonged to B1 evolution branch. 53.48% of the healthy children in Ningbo showed EV71 antibody positive. The geometric mean of the antibody titer (GMT) was 11.23 (8.33 - 14.98) in healthy children. Cox A16 antibody was detected at 63.18% of the healthy children in Ningbo. GMT in healthy children was 12.61 (6.70 - 16.52).</p><p><b>CONCLUSION</b>HFMD was highly endemic in Ningbo, with children under 5 years old were at high-risk. The major etiologic agent was EV71 which belonged to C4a in the C4 sub-genotypes. Cox A16 belonged to the B1 evolution branch, which were in line with the predominant virus circulating in the mainland of China.</p>

Objective To study the epidemiological and etiological characteristics of typhoid and paratyphoid fever in high epidemic areas. Methods Reported data on typhoid and paratyphoid fever during 1988- 2007 in Ningbo were analyzed epidemiologically. Shellfish from the market was collected for laboratory testing and ,Salmonella typhi strains collected from the patients were also studied. Results Number of reported cases on both typhoid and paratyphoid fever was 19 404 with 7 deaths, from 1988 to 2007. The annual mean incidence was 17.68 per one hundred thousand with the fatality rate as 0.36 per thousand. Most cases were among adults aged 20-50 years and an obvious regional distribution was observed with high incidence seen in winter and spring. Since 1990s, the advantage strain had changed from Salmonella typhi to Salmonella paratyphi A. Etiologic studies showed that raw Anadara subcrenata and oyster were the main risk factors. One Salmonella paratyphi A strain was detected in both Anadara subcrenata and oysters collected from the market, which contained TEM-1 drug resistance gene. PFGE genotyping showed that PFGE-X2 was the strain which causing pandemic in Ningbo. Conclusion Eating contaminated raw shellfish like oysters and hairy clams was the primary risk factor, responsible for the outbreaks. Salmonella paratyphi A was the advantages pandemic strain in Ningbo. Strategies as supervision on personal hygiene and health education should be strengthened.
ABSTRACT
Objective To understand the epidemiological characteristics of age distribution of measles and related policies on measles vaccines (live; MV) in infants through analyzing the antibody levels of comparison in maternal-infant pairs. Transition of immunity in infants was also studied to provide theoretic basis for measles immunization strategy and to reduce the incidence of month-old infants. Methods In cities of Ningbo, Harbin, and Jinan from Zhejiang, Heilongiiang and Shandong provinces, data was collected from 2004 to 2007 and analyzed regarding the epidemic situation of measles. Studies on maternal-transferred measles antibody were carried our sero-epidemiologically. Results Most of the measles cases were found among babies younger than 12 months,and the incidence of < 1 year olds had been increasing.The distribution was dominated by 5-8 month olds in infant measles cases. The positive rate and GRMT of measles antibody in newborns were 89.3 percent and 738.93. The positive rate of the measles antibody and GMRT of the 6-month infant were 6.9 % and 6.89, while 6.7 % and 3.69 in 8-month infant. There wasa declining trend of the positive rate of the measles antibody during the newborns to 8-month infant. The positive rate and GRMT of measles antibody in mothers were 84.3 percent and 516.94. Mother's measles antibodies mainly to be at low and moderate level, which accounted for 50.4 percent and 30.3 percent respectively, the correlation coefficient between mother and infant was 0. 840. Conclusion Maternal-transferred measles antibody decreased as the growth of infants. The positive rates of measles antibody were quite low in 6-month and 8-month olds which were the age range that needs most attention.
ABSTRACT
<p><b>OBJECTIVE</b>To better understand the proportions of reported hepatitis B cases in pilot surveillance cites through investigation and laboratory testing.</p><p><b>METHODS</b>To confirm the reported cases of hepatitis B by collecting blood specimen and laboratory testing on HBsAg, IgM of Anti-HBc, Anti-HAV in 18 pilot surveillance counties.</p><p><b>RESULTS</b>Among 2858 cases of hepatitis B reported in 2006, 23.97% of them were reported as suspected acute cases, 14.87% as acute cases, 20.33% as suspected chronic cases, 34.67% as chronic cases, 4.09% as cirrhosis and 2.06% as HCC. Among 1681 reported hepatitis B cases confirmed by laboratory testing, results showed that 24.16% of them were diagnosed as acute hepatitis B, but only 15.37% were confirmed as acute hepatitis B. Although the proportion confirmed as hepatitis B kept consistent as before, misclassification was found.</p><p><b>CONCLUSION</b>In current surveillance system, reported hepatitis B cases were mainly chronic, only up to one third belonged to acute hepatitis B. The reported incidence of hepatitis B did not reflect the real incidence due to misclassification. To better define the burden on hepatitis B disease, it was necessary and urgent to revise the diagnostic criteria and to conduct surveillance on hepatitis B, under separate reporting categories which including acute and chronic cases of the disease.</p>
