Objective: To understand the epidemiological characteristics of viral hepatitis B in Shaoxing from 2008 to 2018,so as to provide basis for formulating the viral hepatitis B prevention and control strategy. Methods: The data of viral hepatitis B cases in Shaoxing from 2008 to 2018 were collected from infectious diseases reporting and management system. Descriptive epidemiological method was employed to analyze the time,place and population characteristics of viral hepatitis B cases in Shaoxing. Annual percentage change（APC）was calculated to analyze the development trend of viral hepatitis B. Results : From 2008 to 2018,a total of 22 764 cases of viral hepatitis B were reported in Shaoxing,with an average annual incidence rate of 42.24/100 000 and a standardized incidence rate of 39.19/100 000. The incidence rate of viral hepatitis B decreased from 2008 to 2018,among which the APC from 2012 to 2018 was -18.00% with a significantly downward trend（P<0.05）. Six counties,cities or districts in Shaoxing reported cases of viral hepatitis B,of which Zhuji（49.40/100 000）,Yuecheng（44.17/100 000）and Xinchang（43.28/100 000）ranked top three in average annual incidence rate. The incidence rate of viral hepatitis B in men was 57.07/100 000,which was higher than 27.33/100 000 in women（P<0.05）.The age of onset was mainly 25-59 years old,with 16 941 cases（74.42%）reported. The top three occupations were farmers,workers and migrant workers,with 15 013（65.95%）,2 730（11.99%）and 1 121（4.92%）cases reported,respectively. Conclusions The incidence of viral hepatitis B in Shaoxing from 2008 to 2018 showed a downward trend. Farmers,workers and migrant workers aged 25-59 years were at high risk of hepatitis B infection.

Objective To explore the clinical significance of early invasive mechanical ventilation for acute respiratory distress syndrome (ARDS) caused by thoracic trauma.Methods We retrospectively analyzed the clinical data of 93 patients of invasive mechanical ventilation in those with ARDS caused by thoracic trauma,and divided them into delayed invasive mechanical ventilation group (n =45) and timely invasive ventilation group (n =48) by the time of invasive mechanical ventilation.We compared the blood gas analysis,oxygen index,heart rate,lactic acid,muscle use score of the two groups before and after invasive mechanical ventilation and the differences of mechanical ventilation time,incidence of complications,mortality and length of hospital stay between the two groups.Results Each index of the delayed invasive mechanical ventilation group and the timely invasive ventilation group was calculated:PaO2 (63.2 ± 12.3,74.2 ± 12.1)mm Hg,PaCO2 (39.4 ±8.7,38.9 +7.6) mm Hg,PaO2/FiO2 (196.2 ± 17.8,231.4 ± 18.2),respiratory rate (27.4 ±3.7,21.1 ± 3.4) beats/min,heart rate (117.2 ± 26.8,96.0 ± 25.1) beats/min,accessory muscle use score (2.69 ± 0.15,1.67 ± 0.10),lactic acid (4.23 ± 1.70,2.12 ± 0.80) mmol/L Except for PaCO2,the differences of each index were statistically significant (t values were respectively 4.346,9.420,3.949,5.436,38.809,7.736; P ＜ 0.05).The duration of mechanical ventilation treatment (10.21 ± 1.50,6.47 ± 1.20) d and the length of hospital stay (21.53 ± 1.90,16.32 ±2.10) d of the delayed group and the timely group were significantly different (t values were respectively 12.518,13.318; P ＜ 0.01).The timely group had significantly lower mortality rate (26.7％ (12/45),14.6％ (7/48)),VAP (46.7％ (21/45),22.9％(11/48)),acute gastric mucosal lesions (33.3％ (15/45),12.5％ (6/48)),MODS (40.0％ (18/45),16.7％ (8/48)) than the delayed group (x2 values were respectively 3.86,5.81,4.49,5.70; P ＜ 0.05).There is no significant difference on the incidence of pneumothorax between the two groups (11.1％ (5/45),8.3％ (4/48)).Conclusion Invasive mechanical ventilation is an effective treatment of ARDS caused by chest trauma.Early invasive mechanical ventilation can reduce the mortality rate and shorten the duration of mechanical ventilation and hospital stay of the patients with ARDS after severe thoracic trauma.

Objective: To analyze the epidemiological characteristics of coronavirus disease 2019 ( COVID-19 ) in Shaoxing from January 23 to March 31, 2020, so as to provide basis for the prevention and control of COVID-19. Methods: The information of the COVID-19 cases in Shaoxing were collected from the National Diseases Prevention and Control Information System and the field investigation by CDCs. A descriptive analysis was used for the epidemiological characteristics, including time, spatial and population distribution, clinical features and exposure history. Results: Totally 42 confirmed cases of COVID-19 were reported by March 31, without deaths. The first case was reported on January 23 and the last one was on February 13. The onset of cases peaked in mid-to-late January. All the counties ( cities or districts ) had confirmed cases, 14 cases were reported in Yuecheng District. Twenty-five ( 59.52% ) cases were 45 years old or over. Thirteen ( 30.95% ) cases were engaged in business and eight ( 19.05% ) cases were unemployed. No cases were found among medical staff. The main clinical symptoms were fever, dry cough, fatigue and imaging features of pneumonia, with nine ( 21.43% ) severe cases and three ( 7.14% ) critical cases. There were 34 ( 80.95% ) imported cases, who mainly came from Hubei Province. Totally 1 955 close contacts were tracked down, among whom 4 cases were confirmed, with the infection rate of 0.20%. Conclusions The COVID-19 cases reported in Shaoxing were mainly aged 45 years or over, severe and imported from Hubei Province. There was no continuous transmission in the community, and no infection in medical staff or deaths.

This study was aimed to investigate the mechanism of leukemia cell apoptosis induced by histone deacetylase inhibitor (HDACI). Flow cytometry was used to detect the apoptosis of leukemia cell lines NB4, U937 and Jurkat, and the changes of mRNA and protein expressions of TRAIL, DR4 and DR5 were detected by Western blot and RT-PCR respectively. The results showed that both TRAIL and DR5 protein and mRNA expressions in NB4, U937 and Jurkat cells increased after treated with sodium butyrate (SB) and in time-dependent manner. However, DR4 mRNA in leukemia cells was not significantly changed after treated with SB. It is concluded that the apoptosis mechanism of leukemic cell lines NB4, U937 and Jurkat induced by SB is closely related to the protein and mRNA expressions up-regulating TRAIL and DR5, but the DR4 may not participate in the apoptosis induced by SB.

Objective Evaluating the effects of Bushen-Gufeigao and breathing movements on the patients with chronic obstructive pulmonary disease of Lung and kidney deficiency TCM pattern. Methods The patients with chronic obstructive pulmonary disease of lung and kidney deficiency TCM pattern were recruited and randomly divided into two groups the treatment group (32 cases) and the control group (34 cases). The control group was treated with the conventional medicine, and the treatment group were added Bufei-Gushengao and breathing movements based on the treatment of control group. Both groups were treated for 1 month. The changes of the clinical symptoms, lung function and frequency of attack and duration of each attack in 10 months after treatment were observed. Results After the treatment, compared with the control group, the TCM patterns scores (5.32 ± 2.67 vs. 9.12 ± 4.11, t=4.424) of the treatment group significantly decreased, while the FVC (3.00 ± 0.49 L vs. 2.71 ± 0.47 L, t=2.408), FEV1 (2.27 ± 0.44 L vs. 1.85 ± 0.54 L, t=3.496), and the percentage of FEV1%(75.62 ± 6.84 vs. 66.86 ± 9.32, t=4.333) increased significantly. In the 10 mouths after the treatment, the treatment group showed significantly fewer patients who had attacked more than 6 times than that in the control group, and the duration of attacks showed significantly fewer minutes in the treatment group than the control group (5.56 ± 1.45 d vs. 8.06 ± 1.80 d, t=6.190). Conclusion Bushen-Gufeigao and breathing movements can effectively improve patient's lung function and symptoms.

Objective To explore the changes and significance of Klotho protein levels in different stages of chronic kidney disease (CKD). Methods From March 2015 to December 2017,176 patients with CKD admitted to nephrology department of Inner Mongolia People＇s Hospital were selected as the study object (CKD group), and 80 healthy patients in our hospital were selected as the control group in the same period. The serum Klotho levels of CKD patients and control group at different stages were detected by double antibody sandwich ELISA, and the differences between each group were compared. Results The serum Klotho level of CKD group (( 4. 84 ± 1. 87) μg／L) was significantly lower than that of the control group ((9. 11± 3. 14) μg／L) ( t＝ 13. 82, P＜0. 01) . One-way anova showed that estimated renal glomerular filtration rate (eGFR),serum albumin (ALB),hemoglobin ( Hb),blood calcium ( Ca) and serum Klotho were gradually decreased,while phosphorus (P) and creatinine (Cr) in serum were gradually increased,and the difference was statistically significant among the five stages( all P＜0. 01). Spearman correlation analysis showed that Klotho level was positively correlated with eGFR and Ca,and negatively correlated with CKD stage,Cr and P (r＝0. 369,0. 160,－0. 200,－0. 250,－0. 230,all P＜0. 05). The multiple linear regression equation showed that Klotho level was positively and independently correlated with eGFR ( t＝ 3. 89, P＜0. 001),and negatively correlated with CKD staging independently (t＝－4. 12,P＜0. 001). Conclusion The expression level of serum Klotho protein in patients with CKD is lower than that of healthy people,and it decreases with the increase of CKD stages,which is closely related to the deterioration of renal function. It can be used as a reference index to evaluate the incidence and severity of CKD.
