Objective:To understand the epidemic characteristics and risk factors of severe fever with thrombocytopenia syndrome (SFTS) in Zhaoyuan City, and to provide basis for the improvement of prevention and control strategies.Methods:Retrospective analysis was performed to collect the SFTS surveillance data and epidemiological investigation results of confirmed cases in Zhaoyuan City from 2011 to 2018 from the "Infectious Disease Report Information Management System of the China Disease Prevention and Control Information System", and the general situation and epidemiological characteristics, onset and treatment, clinical manifestations and contact history of SFTS cases were analyzed by descriptive epidemiology method; 60 cases of SFTS confirmed cases and 120 healthy people in the same village, same sex, and same age group as the confirmed case were selected by case-control study to analyze the risk factors of SFTS.Results:A total of 140 confirmed SFTS cases were reported in Zhaoyuan City from 2011 to 2018, with a fatality rate of 18.57% (27/140); the onset time was mainly from May to August, accounting for 83.57% (117/140); the age of onset was mainly 50 - 80 years old, accounting for 90.00%(126/140); the sex ratio of men to women was 1.06 ∶ 1.00 (72 ∶ 68); the occupation distribution was dominated by farmers, accounting for 92.14% (129/140). In 140 cases of SFTS, the average time intervals from onset to first visit and from first visit to confirmation of diagnosis were 4 and 6 days, respectively; and the average medical visit history from onset to diagnosis was 2 times, 60.71% (85/140) of the cases were first diagnosed by township medical institutions, 86.43% (121/140) of the cases were diagnosed by municipal hospitals; the first symptom was fever, which accounted for 92.86% (130/140). The logistic regression analysis showed that domestic animals [odds ratio ( OR)=9.209, 95% confidence interval ( CI): 2.064-41.083] and tick bites ( OR = 16.818, 95% CI: 1.553 - 182.164) were risk factors for SFTS. Conclusions:The onset time of SFTS is mainly from May to August in Zhaoyuan City, and farmers over 50 years old are the key population; domestic animals and tick bites are the risk factors for the onset of SFTS. The publicity and health education of SFTS prevention and control knowledge for key populations should be strengthened.

Objective To observe the clinical therapeutic effect of oral solution of Huaixue Shenshu for treatment of patients with IgA nephropathy and explore its mechanism. Methods A prospective study was conducted. Forty patients with IgA nephropathy diagnosed by pathology were selected, and they were randomly divided into treatment group and control group, 20 cases in each group. The two groups were subjected to the routine treatment, and on this base, the control group also received cozaar 50-100 mg, while the treatment group additionally received oral solution of Huaixue Shenshu decoction (drug composition:Centellae herba 15 g, Sophorae Flos 20 g, Ecliptae Herba 20 g, Ligustri Lucidi Fructus 15 g, Cicadae Periostracum 15 g, Pyrolae Herba 20 g, Saposhnikoviae Radix 10 g, Astragali Radix 15 g, the above ingredients were immersed in water and boiled to form 200 mL decoction, as a dose, and then divided into two parts to take orally one of them each time, twice a day). Both groups took two therapeutic courses in total, 3 months constituting one course. After treatment, the integral changes of clinical symptoms and clinical efficacy were observed, and before treatment and 3 months and 6 months after treatment, the 24-hour urine protein, serum creatinine (SCr), and albumin (Alb) were measured in the two groups. Results Before treatment, there was no significant difference in integral of clinical symptoms between treatment group and control group (score: 18.42±5.41 vs. 19.95±6.25, P>0.05);after treatment, the integrals of two groups were significantly lower than those before treatment, and the degree of decrease in treatment group was more obvious (score: 6.35±2.11 vs. 9.45±3.55, P < 0.05). After treatment the total effective rate in treatment group was significantly higher than that in control group [75.0% (15/20) vs. 40.0% (8/20), P<0.05]. Before treatment, the differences in 24-hour urinary protein, SCr and Alb were not significant between the two groups (all P > 0.05); with the prolongation of treatment, the 24-hour urinary protein was decreased gradually, and Alb was increased gradually, reaching its peak after 6 months of treatment, and the changes were more obvious in treatment group [24-hour urinary protein (g):0.71±0.58 vs. 1.31±0.55, Alb (g/L):37.8±6.1 vs. 35.5±5.2, both P<0.01]. No significant difference in SCr was found before and after treatment between the two groups (both P > 0.05). Conclusion The effect of oral solution of Huaixue Shenshu in treatment of IgA nephropathy is good.

Objective To assess the effects of fluid resuscitation in elderly patients with septic shock by right ventricular end-diastolic volume index (RVEDVI). Method Thirty elderly patients with septic shock with-in 6 hours after onset, admired to intensive care unit of Zhejiang Hospital from January 2007 to October 2008, were randomly divided into control group (n = 15) and experimental group (n = 15). Homodynamic profile of the right ventricular was monitored by using modified Swan-Ganz catheter. Fluid resuscitation was given to the patients of control group monitored by right atria pressure (RAP). The expected efficacy of treatment was the RAP elevated to 8 ～ 12 mmHg. The goal of fluid resuscitation in patients of experimental group was 100～ 200 mL/m~2 RVEDVI corrected by right ventricular ejection fraction (RVEF). RAP, pulmonary artery occlusion pressure (PAOP), RVEF, RVEDVI, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and mixed venous oxygen sat-uration (SvO_2) were recorded before and after the treatment for 6 hours in both groups. The concentration of lactate and the lactate clearance rate of patients in both groups after fluid resuscitation were detected. The relationship between lactate clearance rate and ARVEDVI was evaluated by using correlation analysis. Results The percentage of patients reaching goal of resuscitation in experimental group (86.7%) was higher than that in control group (80%), however, there was no significant difference statistically. In goals-achieving group, RVEDVI, △RVEDVI, RVEF(%), RAP and lactate clearance rate(%) of the patients in experimental group were signifi-cantly higher than those in control group [(119.92 ± 15.65) mL/m~2, (38.54 ± 6.63) mL/m~2, (36.08 ± 3.40), (14.46±1.13) mmHg,(58.31 ± 13.36) vs. (99.92±11.71) mL/m~2,(21.00±11.01) mL/m~2,(32.42± 2.47),(13.08±1.08) mmHg,(43.99±16.26); P <0.05]. However, there was no significant difference in PAOP, APACHE Ⅱ and SvO_2 between two groups (P >0.05). The lactate clearance rate in goals-achieving pa-tients with septic shock has a significant correlation with RVEDVI and △RVEDVI (P < 0.01). Conclusions Fluid resuscitation guided by RVEDVI in elderly patients with septic shock is safe and more effective than that guided by RAP.
