To explore the relationship between meteorological factors and incidences of fever, thrombocytopenia and leukopenia syndrome (FTLS), incidence data of FTLS in Xinyang City were collected and described. The relationship between FTLS and monthly meteorological factors such as average atmospheric pressure, average temperature, average relative humidity, average wind speed and precipitation was analyzed with simple correlation and multi-stepwise linear regression. The results showed that there was a significant negative correlation between incidence of FTLS and monthly average atmospheric pressure (P<0.01), and there were significant positive correlations between monthly average temperature, monthly average relative humidity, monthly precipitation and incidence of FTLS (P<0.05). The multi-stepwise regression showed that the regression equation was Y (monthly cases) =-12.70 + 0.28X2 (monthly average temperature), and the coefficient of determination was 0.76. The incidences of FTLS are correlated with temperature.

OBJECTIVETo compare the efficacy of telbivudine monotherapy and telbivudine combination therapy with adefovir in patients with nucleos(t)ide-naive chronic hepatitis B, high-level hepatitis B virus (HBV) load and hepatitis B e antigen (HBeAg)-positivity, and to explore the relationship between treatment regimen adherence and treatment outcomes.
METODSA retrospective study was performed with 123 HBeAg-positive, high-level viral load (HBV DNA≥10(7) copies/ml), nucleos(t)ide-naive chronic hepatitis B patients. Fifty-three of the patients received combination therapy with telbivudine and adefovir dipivoxil,while 70 patients received the telbivudine monotherapy. All patients were tested for rates of conversion to HBV DNA-negative status,alanine aminotransferase (ALT) normalization, HBeAg seroconversion, drug resistance, and side effects at treatment weeks 12, 24, and 48. Treatment regimen adherence was assessed through self-reporting, and interviews were used to explore the relationships to treatment outcomes. The chisquare test, t test and Fisher's exact test were used for statistical analyses.
RESULTSThe rates of HBV DNA negative conversion in the combination group at treatment weeks 12, 24 and 48 were 62.3% (33/53), 88.7% (47/53) and 94.3% (50/53) and were significantly different from those in the monotherapy group at weeks 12 and 24.The rates of ALT normalization were significantly different between the two groups at treatment week 12 (94.3% vs. 77.1%). The rate of HBeAg seroconversion in the combination group at treatment week 48 was 39.6%, and significantly different than that of the monotherapy group. The rates of drug-resistance in the combination and monotherapy groups at treatment week 48 were 3.8% and 11.4%, and the proportion of non-adherence to the treatment regimen was 53.3%, which significantly affected treatment outcome. No side effects occurred in either treatment group.
CONCLUSIONTelbivudine combination treatment with adefovir was more effective than telbivudine monotherapy and elicited a low drug resistance rate in nucleos(t)idenaive chronic hepatitis B patients with high-level HBV load and HBeAg-positivity. Adherence to the therapy regimen was a key factor influencing treatment outcomes.

Objective:To analyze the effects of multidisciplinary cooperative nutrition management model in acute stroke patients with dysphagia.Methods:From February 2019 to February 2020, 69 acute stroke patients with dysphagia were enrolled in this study. After exclusion of those unable to complete the trial, patients were randomized into control group ( n=30) and experimental group ( n=30). Patients in the control group were given routine nutrition management, while patients in the experimental group were treated under multidisciplinary cooperative nutrition management model. Nutritional indicators were compared between the two groups on Day 1, 7 and 14 after admission, including levels of albumin (ALB), pre-albumin (PALB), hemoglobin (HB), triceps skin-fold (TSF) thickness on the uninjured side, upper arm muscle circumference etc. Incidence of gastrointestinal complications and infectious complications was also recorded. Results:There was no difference between two groups in the levels of HB, TSF thickness and upper arm muscle circumference on the uninjured side (all P>0.05). However, the serum levels of ALB and PALB on Day 7 and 14 in the experimental group were higher than that in the control group(all P<0.05), The incidence of gastrointestinal complications ( P=0.015)and infectious complications ( P=0.016) in the experimental group was lower than that in the control group. Conclusion:Multidisciplinary collaborative nutrition management improved nutritional indicators, reduced the incidence of gastrointestinal complications and infectious complications in acute stroke patients with dysphagia, making multidisciplinary collaborative nutrition management model worthy of clinical promotion and application.

Objective:
To confirm the laboratory diagnosis of dengue bordline cases reported in Henan Province and trace its origin from molecular level in 2017.
Methods:
The study samples were blood samples (3-5 ml), which came from 8 suspected cases of dengue fever reported in the 2017 direct reporting system of Henan provincial infectious disease monitoring network. Meanwhile, case investigation was conducted according to National dengue fever surveillance programme. Serum were separated from blood samples and tested for Dengue NS1 antigen, IgM & IgG antibodies, and dengue RNA. According to dengue diagnosis criteria, confirmed cases were identified by testing results. Samples carried dengue RNA performed for real-time PCR genotyping and amplification of E gene. Then, the amplicons were sequenced and homological and phylogenetic analyses were constructed.
Results:
8 serum samples of suspected dengue cases were collected in Henan Province, 2017. Six of them were diagnosed as dengue confirmed cases. All the dengue confirmed cases belonged to outside imported cases, 5 of them were positive by dengue RNA testing. Genotyping results showed there were 1 DENV1 case, 2 DENV2 cases and 2 DENV3 cases. A DENV2 case and a DENV3 case of this study were traced its origin successfully. The sequence of Pakistan imported DENV2 case belongs to cosmopolitan genotype, which was the most consistent with Pakistan's DENV2 KJ010186 in 2013 (identity 99.0%). The sequence of Malaysia imported DENV3 case belongs to genotype I, which was the most consistent with Singapore's DENV3 KX224276 in 2014(identity 99.0%).
Conclusion
The laboratory diagnosis and molecular traceability of dengue cases in Henan Province in 2017 confirmed that all cases were imported and did not cause local epidemics.

OBJECTIVETo investigate the inhibitory effects of curcumin against HeLa cell invasion and migration and explore the underlying mechanisms.
METHODSHeLa cells were exposed to curcumin treatment at the concentrations of 0, 10, 25, 50, 100, 150 and 200 µmol/L for 24 h. MTT and TUNEL assays were used to assess the cell proliferation inhibition and apoptosis, respectively. Transwell assay was used to evaluate the invasiveness and migration of the treated cells, and RT-PCR and Western blotting were employed to detect the changes in the expression of inducible nitric oxide synthase (iNOS), and MMP-9 and E-cad, the 2 markers of cell invasion and migration, were detected by Western blotting. The capacity of NO production in HeLa cells was measured by Griess method.
RESULTSCurcumin inhibited the proliferation of HeLa cells by inducing cell apoptosis in a concentration-dependent manner. Curcumin inhibited the invasion and migration of HeLa cells by increasing E-cad expression and decreasing MMP-9 expression, and also decreased the expression level of iNOS and NO production in the cells.
CONCLUSIONCurcumin inhibits the invasion and migration of HeLa cells by decreasing the expression of iNOS.
