Objective: To analyze the epidemiological characteristics of notifiable infectious diseases reported in Zhejiang Province in 2020 for prevention and control. Methods: Data of notifiable infectious diseases reported in Zhejiang Province in 2020 were extracted from China Information System for Disease Control and Prevention. The incidence and death of notifiable infectious diseases were analyzed and compared with the averages from 2015 to 2019; then the characteristics of some key diseases such as coronavirus disease 2019 ( COVID-19 ), influenza and other infectious diarrhea were summarized. Results: Totally 487 271 cases of 30 kinds of infectious diseases were reported. The incidence and mortality rate was 832.94/100 000 and 0.615 4/100 000, which were 7.05% and 14.60% lower than the average value of 2015-2019.The weekly morbidity of Class A and Class B infectious diseases fluctuated between 1.24/100 000 and 3.68/100 000, and hit the bottom in the sixth to eighth week. The morbidity of Class C infectious diseases was 154.19/100 000 in the first week, then dropped to 4.83/100 000 in the second to sixth week and maintained at a low level. High morbidity of infectious diseases were reported in Hangzhou ( 1 412.62/100 000 ), Jinhua ( 960.35/100 000 ) and Ningbo ( 921.25/100 000 ). The morbidity of class C infectious diseases in Hangzhou was 1 248.80/100 000, which was far higher than that of other ten prefecture-level cities. The diseases with high reported morbidity were influenza (438.45/100 000), other infectious diarrhea (140.29/100 000 ), hand-foot-and-mouth disease ( 99.64/100 000 ), pulmonary tuberculosis ( 41.92/100 000 ), syphilis (41.37/100 000) and viral hepatitis ( 30.48/100 000 ). More deaths were reported in AIDS and pulmonary tuberculosis, and the mortality were 0.482 1/100 000 and 0.116 2/100 000. A total of 1 306 confirmed cases, 302 asymptomatic infections and 1 death of COVID-19 were reported. Conclusion In 2020, the incidence rate of notifiable infectious diseases in Zhejiang decreased compared with the average value of 2015-2019. Pulmonary tuberculosis, syphilis and hepatitis B still have high morbidity, and the COVID-19 epidemic spread widely. The morbidity of some respiratory infectious diseases and imported infectious diseases have dropped significantly compared with previous years.

OBJECTIVE: To study ApoB gene genetic polymorphism of Han nationality and Mongolian nationality in midwest area of Inner Mongolia. METHODS: Some unrelated individuals of Han nationality and Mongolian nationality in midwest area of Inner Mongolia were selected. Polymerase chain reaction-restriction fragment length polymorphism technology was used to check the presence of Xba I (X+) and EcoR I (E-) sites of rare alleles. The genotype frequency, allelic frequency and population genetics parameters were calculated. RESULTS: The frequencies of Xba I (X+) and EcoR I (E-) rare alleles were 2% and 4.6% in Han population. There was no Xba I (X+) or EcoR I (E-) rare alleles found in Mongolian nationality. CONCLUSION The allelic frequencies of ApoB gene Xba I and EcoR I sites are very different in different races. These sites may be used in identification of ethnicity.

Objective To explore the effects of different doses of topiramate (TPM) on the expression of nerve cell adhesion molecule (NCAM) and growth-associated protein 43 (GAP- 43) mRNA in hippocampus of rats with epilepsy. MethodsForty-eight rats were randomly divided into normal control group, kainic acid (KA) group, 10 mg/kg TPM group, 40 mg/kg TPM group, 100 mg/kg TPM group and 400 mg/kg TPM group (n=8). The models of rats with epilepsy treated by different doses of TPM were established. The behavior of rats was observed, and the expression of NCAM and GAP- 43 mRNA in hippocampus of rats was determined by Real-time PCR. Results The expression of NCAM and GAP- 43 mRNA in KA group was significantly higher than that in normal control group (P<0.01), while there was no significant difference between 10 and 40 mg/kg TPM groups and KA group, that in 100 and 400 mg/kg TPM groups was significantly lower than that in KA group (P<0.01), and that in 400 mg/kg TPM group was significantly lower than that in 100 mg/kg TPM group (P<0.01). Conclusion KA can up-regulate the expression of NCAM and GAP- 43 mRNA in hippocampus of rats with epilepsy. Higher dose of TPM can inhibit the expression of NCAM and GAP- 43 mRNA, and the inhibitory effect is related with the dose of TPM.

Objective To explore the prognostic value of arterial blood lactate (Lac) levels and lactate clearance rate (LCR) in the patients with septic shock.Methods A retrospective study was conducted.Clinical data of 94 septic patients admitted in the Department of Critical Care Medicine in Subei People's Hospital from January 2011 to June 2014 were analyzed.The arterial blood Lac levels at the moment of diagnosis of septic shock (incipient value,0 hour) and early-stage after treatment (3,6 and 24 hours) were reviewed,and individual LCR was calculated at 3,6,24 hours for each patient.According to the outcome in intensive care unit (ICU),patients were divided into survival group (n =48) and death group (n =46).The Lac and LCR at different time points in two groups were analyzed,and the relationships between them and outcome were analyzed.The receiver-operating characteristic (ROC) curve was plotted to assess the value of Lac and LCR at different time points for predicting the outcome.Results Lac level after treatment in survival group was significantly lower than incipient value,but there was no obvious change in death group.Compared with death group,early Lac levels (mmol/L) in survival group were significantly reduced (0 hour:3.80 ± 2.14 vs.5.75±3.21,3 hours:2.05± 1.04 vs.5.03±2.53,6 hours:1.80±0.77 vs.4.40±2.02,24 hours:1.35±0.43 vs.4.90 ± 2.72,P ＜ 0.05 or P ＜ 0.01),the LCR was significantly increased [3 hours:50.00 (72.35)％ vs.13.51 (20.67)％,6 hours:41.43 (58.42)％ vs.22.00 (22.31)％,24 hours:58.73 (29.94)％ vs.18.92 (47.28)％,P ＜ 0.05 or P ＜ 0.01].The Lac levels at all time points were positively correlated with the outcome,and 6-hour and 24-hour LCR were negatively correlated with the outcome.According to the incipient Lac level,patients were divided into low Lac group (Lac ＜ 2 mmol/L),mild Lac group (Lac 2-3 mmol/L) and high Lac group (Lac ≥ 4 mmol/L).The mortality in low Lac group,mild Lac group,high Lac group was gradually increased [23.07％ (6/26),50.00％ (8/16),61.54％ (32/52),x2=10.270,P =0.006].ROC curves demonstrated that the area under ROC curve (AUC) of 24-hour Lac was the largest,0.944,and it was more sensitive and specific in the prognosis evaluation (100％ and 78.3％,respectively).According to the cut-off value of 24-hour Lac as 2.35 mmol/L,patients were divided into high Lac and low Lac groups,and mortality rate in high Lac group was significantly higher than that in low Lac group [100.0％ (36/36) vs.17.24％ (10/58),x2=30.441,P =0.000].The AUC of 24-hour LCR was the largest,0.865,and it was more sensitive and specific for the prognosis evaluation (83.3％ and 91.3％,respectively).According to the cut-off value of 24-hour LCR as 36.8％,patients were divided into high LCR group and low LCR group,and mortality rate in low LCR group was significantly higher than that in high LCR group [84.00％ (42/50) vs.9.09％ (4/44),x2=26.278,P =0.000].Conclusion Early high Lac in patients with septic shock prompts a poor prognosis,and 24-hour Lac levels and LCR are indicators of assessment of clinical therapeutic effect and prognosis of patients with septic shock.
