Objective To explore the effect of diabetic liaison nurses on controlling blood sugar levels in patients with hyperglycemia in department other than endocrinology. Methods Four hundred diabetic patients with high blood sugar were selected from January to December, 2014 in department other than endocrinology. They were divided randomly into 2 groups equally:the control group and the observation group. The control group received traditional nursing care, while blood sugar management was carried out by diabetic liaison nurse in the observation group. Result Pre-discharge sugar metabolism in the observation group was significantly better than that in the control group (P<0.05). Conclusion The diabetic liaison nurses in other departments than the endocrinology department can help control blood sugar levels in patients with hyperglycemiain.

Abstract: Objective　To analyze the laboratory microscopic re-examination results of malaria cases in Nantong of the National Notifiable Disease Report System from 2014 to 2021 by Nantong Malaria Diagnostic Reference Laboratory, so as to evaluate the malaria diagnosis ability of Nantong Malaria Diagnostic Reference Laboratory. Methods　The blood smear and blood samples of malaria cases in Nantong from 2014 to 2021 of the National Notifiable Disease Report System were collected. Nantong Malaria Diagnostic Reference Laboratory and Jiangsu Institute of Parasitic Diseases carried out the re-examination of municipal and provincial laboratories, taking the results of provincial laboratory as the standard to compare and analyze the re-examination results of Nantong Malaria Diagnostic Reference Laboratory. Results　From 2014 to 2021, the two-level laboratories in Nantong city and Jiangsu Province re-examined the blood samples of 297 malaria cases. The microscopic examination and PCR re-examination results at the provincial level were the same：292 positive cases and 5 negative cases. The qualitative coincidence rate between Nantong microscopic re-examination results and the provincial re-examination results was 100% (297/297), without misjudgment and omission. The coincidence rate of Plasmodium typing was 96.23% (281/292). The coincidence rate of P. falciparum, P. vivax, P. ovale and P. malaria were 99.57% (234/235), 62.50% (5/8), 89.47% (34/38) and 72.73% (8/11) respectively. The consistency test results showed that the Kappa value of Plasmodium typing results between municipal and provincial laboratories was 0.89. The Kappa values of P. falciparum, P. vivax， P. ovale and P. malaria were 0.98, 0.58, 0.87 and 0.79 respectively. Conclusion　The malaria diagnosis ability of Nantong Malaria Diagnostic Reference Laboratory is generally good, and it is necessary to improve the ability of Plasmodium typing.

Objective To investigate insulin resistance and the effect of physical training on it in the pa- tients with chronic heart failure (CHF). Methods One hundred and twenty NYHAⅡ-ⅢCHF patients were ran- domly divided into a training group( n = 65 ) and a routine therapy group (n = 55 ). Another 35 healthy subjects were recruited as control group. All the patients were treated with routine anti-CHF drugs, and the training group patients had received physical training twice a day in addition. The HOMA-IR, insulin sensitivity index (ISI) , left ventricu- lar ejection fraction (LEVF), left ventricular fractional shortening( LVFS), 6-minute walking distance, heart rate and mean blood pressure were compared between the training and routine therapy groups before and after physical ex- ercise in both groups, and a comparison was made between the patients and the controls before the intervention with regard to HOMA-IR and ISI. Results Comparing with control group, ISI was reduced while the HOMA-IR in- creased (P

Objective To investigate the epidemiological characteristics and diagnosis of malaria cases in Nantong City from 2015 to 2020, so as to provide insights into the prevention of re-establishment of imported malaria and consolidation of malaria elimination achievements in the city. Methods The epidemic data of malaria in Nantong City from 2015 to 2020 were captured from the National Notifiable Disease Report System, the Information Management System for Parasitic Disease Control and individual epidemiological survey reports of malaria cases. The malaria parasite species, source of infections, population distribution, temporal distribution, spatial distribution and diagnosis of imported malaria cases were descriptively and statistically analyzed. Results A total of 241 malaria cases were reported in Nantong City from 2015 to 2020, and all were overseas imported cases, including 191 cases with Plasmodium falciparum malaria (79.25%), 8 cases with P. vivax malaria (3.32%), 33 cases with P. ovale malaria (13.69%) and 9 cases with P. malaria malaria (3.73%). Overseas imported malaria cases acquired infections from 34 countries in Asia, Africa and Latin America, and 97.93% of the cases were infected in Africa, and 90.04% (217/241) were reported in Chongchuan District, Hai’an City and Haimen District. Imported malaria cases were aged from 20 to 68 years, and a median age of 45 (13) years, and 97.10% were male. The median duration between returning to China and malaria onset was 7 (9) days among all imported malaria cases, and the median duration from initial diagnosis to definitive diagnosis was 2 (2) days. There were 167 cases that were initially diagnosed as malaria, with a correct rate of 69.29%, and 53.53 (129/241) of malaria cases were diagnosed at city-level medical institutions and 41.49% (100/241) at county-level medical institutions. In addition, the proportion of malaria cases reported by city-level medical institutions increased from 39.62% in 2015 to 81.25% in 2020 (χ² = 6.94, P < 0.01). Conclusions The accuracy of initial malaria diagnosis requires to be improved in Nantong City. Malaria control knowledge should be specially given to migrant workers to shorten the duration of seeking medical care, and malaria training requires to be intensified among healthcare professionals to improve the diagnostic capability of imported malaria cases and the cure of severe P. falciparum malaria cases.

OBJECTIVETo analyze the spatial distribution of hemorrhagic fever with renal syndrome (HFRS) in Haidian district, Beijing and to explore the geographical characteristics of HFRS in highly endemic areas.

METHODSAdministration boundary layer was established under the background of 1:100,000 map in the ArcInfo 8.1 software. The HFRS cases from 1997 to 2002 were positioned on the map. Highly endemic areas were identified by spatial cluster analysis using SaTScan 3.0 software. Distribution of HFRS cases was shown in different colors and contours by spatial analysis of geographic information system (GIS).

RESULTSSpatial Cluster Analysis of confirmed cases of HFRS identified in 1997 - 2002 in Haidian district showed that HFRS patients were not randomly distributed. The highly endemic areas were founded in Sujiatuo township, Yongfeng township, Shangzhuang township, Wenquan town and Bei'anhe township (relative risk = 4.43, P = 0.001). A thematic map of HFRS in haidian district was set up.

CONCLUSIONHFRS infections were not randomly distributed, since the distribution was related to geographic-environmental factors.

Objective To understand the forming cause of the Oncomelania hupensis snail-existent non-endemic areas of schistosomiasis(SENEAS),and to verify the conclusion of previous studies,so as to provide the evidence for schistosomiasis monitoring in such areas in Nantong City,Jiangsu Province. Methods The controlled field tests were carried out to observe the O. hupensis snails artificially infected by schistosome miracidia in SENEAS. The influence of the soil from SENEAS and the en-demic areas on O. hupensis snails artificially infected by miracidia were observed. Results All the experimental snails could be infected by schistosome miracidia except the smooth-shell snails from Tangyuan Village in the controlled field test environment of SENEAS or the endemic areas. The infection rates of the smooth-shell snails were lower than those of the ribbed-shell snails , but there were no statistically significant differences. The mortality rates of the smooth-shell snails were higher than those of the ribbed-shell snails,which were statistically significant (χ2Xindian = 135.118,χ2Shuangdian = 122.836,χ2Baipu =154.436,χ2Dingyan =138.288,χ2Control=151.923,all P<0.01). There were no significant differences in the infection rates of snails between each test group of the soil from SENEAS and the endemic areas(χ2Rugao=0.071,χ2Rudong=0.216,both P>0.05). Also there was no signifi-cant difference between each test group and the control group without soil(χ2=7.148,P>0.05). Conclusion It is likely to form the spread of schistosomiasis in SENEAS in Nantong City with sufficient amount of infection source of schistosomiasis im-ported. It is still necessary to implement the surveillance of schistosomiasis and O. hupensis snails in Nantong City.

Objective To retrospectively analyze the epidemic situation and diagnosis and treatment of severe falciparum malaria in Nantong City, summarize the causes of severe falciparum malaria, and evaluate the effect of diagnosis and treatment, so as to provide the evidence for formulating the practical treatment measures for this disease. Methods All the data of falciparum malaria cases in Nantong City from 2009 to 2016 were collected and analyzed for the onset time, diagnosis process and treatment of the disease. Results A total of 359 malaria cases, including 289 falciparum malaria cases, were reported in Nantong City from 2009 to 2016, including 26 severe falciparum malaria cases. All the severe falciparum malaria cases were imported from Africa, including 57.70% of cases (15/26) from Angola. All of them were male labor exporting personnel. The incidence of malaria was not obviously seasonal. The average time from onset to definite diagnosis was 5.2 days, and 11 cases were diagnosed 5 days after the onset. All the 26 cases were cured by anti-malaria treatment and symptomatic treatment, and there was no death. Conclusions Severe falciparum malaria seriously harm the people’s health and its clinical manifestations are complicated. Therefore, the training of medical staff and health education in residents, especially in labor exporting personnel, should be further strengthened.

The invasive fungal infections (IFI) in immunocompromised patients are associated with a high mortality rate and diagnostic difficulty. Serological methods such as aspergillus galactomannan assay (GM test) and (1, 3)-beta-D glucan (BG) assay (G test) can be used as an adjunctive method for IFI diagnosis based on their characteristics of easy-operating, rapidness and high sensitivity. Compared with GM test, G test can be more widely used except for the diagnosis of aspergillosis. The purpose of this study was to investigate the value of G test in the diagnosis of IFI in patients with hematological disorders. The plasma was collected from 162 suspected IFI patients with hematological disorders in Beijing Daopei Hospital, including 85 patients after chemotherapy and 77 patients after stem cell transplantation from May 2007 to May 2008, BG level was measured with MB-80 Microbiology Kinetic Rapid Reader and the measured results together with the clinical characteristics were retrospectively analyzed. According to the European Organization for Research and Treatment of Cancer/Mycoses Study Group (EORTC/MSG) criteria, there were 2 patients diagnosed as proven IFI, 18 as probable IFI, 75 as possible IFI and 67 as no IFI. The results showed that at a cutoff of 20 pg/ml, the sensitivity and specificity of G test were 75% and 91% respectively, with a positive predictive value (PPV) of 71.4% and a negative predictive value (NPV) of 92.4%. 51 out of the 75 possible IFI patients with elevated BG level were responsive to antifungal treatment but non responsive to broad-spectrum antibiotics, retrospectively were diagnosed as IFI, suggesting that G test improved the IFI diagnostic rate by 31.4%. In conclusion, G test is a rapid and simple method for early diagnosis of IFI in patients with hematological disorders.

Objective To disclose the relationship between current smoking behaviors and household characteristics among adults in Guangdong,in order to provide scientific evidence for household tobacco control strategy. Methods A questionnaire survey was conducted among the adults sampled by four-stage randomized cluster sampling in ten districts of five cities in Guangdong from September to November,2010. The questionnaire included demographic characteristics,smoking behaviors and smoking-related household characteristics. Chi-square test and unconditional logistic regression analysis were employed to explore the relationship between current smoking behaviors and household characteristics. Results This study included 2 150 respondents,with data from 2 121 eligible questionnaires used for analysis. The current smoking rates for respondents with household characteristics including per capita household income below 1 000 Yuan,three or more smokers in the family,no ban of smoking at home and treating visitors with cigarettes were 28.7%,56.5%,34.2%and 43.5%,respectively,and were significantly higher than those for respondents with household characteristics at other levels(P<0.01 for all). After controlling for factors such as gender,age, personal income,education,employment status and residential location,we found that the number of family smokers,smoking restrictions at home and treating visitors with cigarettes had significant association with current smoking behaviors(P<0.01 for all),except for per capita household income (P=0.567). Conclusion Household is one of the effective places in carrying out health education and tobacco control intervention. In order to reduce tobacco use,much effort should be made to create smoke-free homes,encourage smoking cessation and treat visitors with no cigarettes.

BACKGROUNDChromosomal abnormalities have been shown to play an important prognostic role in multiple myeloma (MM). Interphase fluorescence in situ hybridization (i-FISH) has been much more effective to identify cytogenetic aberrations in MM than conventional cytogenetic technique (CC). To clearly determine the cytogenetic features of Chinese MM patients and identify their prognostic implications, we designed a multicenter study based on i-FISH including 672 patients from 52 hospitals in China.

METHODSAll 672 patients were systematically screened for the following genomic aberrations: del(13q), IgH rearrangement, del(p53) and 1q21 amplifications.

RESULTSThe analysis showed that the chromosomal changes were detected in 22.1% patients by CC and in 82.3% patients by i-FISH. The most common abnormalities by CC were chromosome 1 aberrations (48.4%), -13/13q- (37.6%), hyperdiploidy (36.6%), hypodiploidy (30.1%) and IgH rearrangements (23.7%). The most frequent abnormalities by FISH was del(13q), which was found in 60.4% patients, whereas IgH rearrangement, 1q21 amplification and p53 deletions were detected in 57.6%, 49.0% and 34.7% cases, respectively. By statistical analysis, -13/13q- by CC was associated with low level of platelet (P = 0.015), hyperdiploidy was associated with low level of serum albumin (P = 0.028), and IgH rearrangement by FISH was associated with high level of β2 microglobulin (P = 0.019). Moreover, 1q21 amplification and del(p53) by FISH conferred a high incidence of progressive disease (PD) after initial therapy. Metaphase detection of IgH rearrangements and chromosome 1 aberrations concurrently was associated with a short progression free survival (PFS) (P = 0.036). No significant prognostic implications of other cytogenetic abnormalities were found associated with overall survival and PFS.

CONCLUSIONSChinese MM patients had similar cytogenetic abnormalities compared with the previous reported studies. However, the prognostic significance of FISH aberrations were not clearly determined and further study is required.
