AIM: To observe the function and morphological change of human umbilical vein endothelial cells(HUVECs) treated with lipopolysaccharide(LPS) and composite salviae dropping pills(DSP).METHODS: HUVECs were cultured and incubated within 10 mg/L LPS for 12 hours.Different final concentrations of composite salviae dropping pills(1 g/L,0.5 g/L,0.25 g/L,0.1 g/L) were added before and after LPS treatment. Cell viability,NO,NOS,ET-1 and intracellular calcium were measured.The cells were observed under inverted microscope,inverted phase contrast microscope,laser confocal scanning microscopy and transmission electron microscope.RESULTS: When given after LPS treatment,different final concentrations of composite salviae dropping pills played a protective role(P0.05).The HUVECs injured by LPS underwent apparent morphological change after treatment with composite salviae dropping pills.CONCLUSION: Composite salviae dropping pills have an evident protective effect on human umbilical vein endothelial cells exposed to LPS.

AIM: To observe the protective effect of composite salviae dropping pills against human umbilical vein endothelial cells(HUVECs) injure induced by hydrogen dioxide(H_2O_2) and discuss the mechanism of its therapeutic action on cardiac and encephalic diseases.METHODS: HUVECs were injured by 0.1 mmol/L H_2O_2 and then different final concentrations of composite salviae dropping pills(0.5 g/L,0.25 g/L,0.1 g/L) were added before and after the injury.Cell viability was measured by MTT assay.TBA method was used to detect the intracellular malonaldehyde. Nitric oxide(NO) in the culture medium was detected by using nitrate reductase assay,and immunocytochemisty was used to observe the expression of NOS2,NOS3 and NF-?B.Morphologic observation was also performed.RESULTS: HUVECs were injured by 0.1 mmol/L H_2O_2.Composite salviae dropping pills increased the cell viability apparently,inhibited the production of MDA induced by H_2O_2,regulated the generation of NO bilaterally and influenced the expression of NOS3 and NF-?B.CONCLUSIONS: Composite salviae dropping pills at concentrations of 0.5 g/L,0.25 g/L and 0.1 g/L protects HUVECs from injury by H_2O_2,no matter it is be added before or affter the injury.The possible mechanism is associated with its regulating the expression of NOS2,NOS3 and NF-?B.

Objective To investigate the clinical value of blood vessel diameter tracking and X-strain technology in evaluating the carotid elasticity in patients with diabetes.Methods Thirty-eight patients who were confirmed as diabetes without complications were enrolled in this study as the patient group and thirtyseven healthy volunteers matched with the patient group with sex,ages were typed as controls.The parameters reflecting common carotid elasticity:pulse wave velocity ( PWV),compliance coefficient (CC),stiffness index ( β),endovascular circumferential strain,strain rate,strain time ( EN _ CS,EN _ CS_ T,EN_CSR,EN_CSR_T),adventitial circumferential strain,strain rate,strain time (EP_CS,EP_CS_T,EP_CSR,EP_ CSR_ T),radial strain ( RS),radial strain rate (RSR) and radial strain time (RST) were measured using blood vessel diameter tracking technique and X-strain technique.Significant difference between the two groups and correlations among these variables were evaluated.Results In patient group,PWV and β were significantly higher than those of the control group,while variables like CC,EN_CS,EN_CSR,EP_CS,EP_CSR,RS and RSR were lower with P ＜0.05.All strain time prolonged in patient group ( P ＜0.05).No significant differences were observed in longitudinal strain index.Furthermore,CC was inversely related with PWV( r =- 0.872,P ＜0.001 ),and age,systolic pressure,β were positively related with PWV ( r =0.322,P =0.005; r =0.384,P =0.001; r =0.927,P ＜0.001) in patients group.Conclusions The stiffness and compliance indexes measured by blood vessel diameter tracking technique and the circumferential and radial strain index obtained by X-strain technique can reflect vessel elasticity change of patient with diabetes objectively.

In the process of conducting implementation research on health service issues, stakeholders' preference for contents related to evidence-based practice (EBP) and implementation strategies is closely related to whether EBP can be effectively implemented.However, multiple preference assessment methods exist, each with their own strengths, weaknesses, and application scenarios, which makes it challenging for researchers to select appropriate and effective preference assessment methods. This paper aims to review the origins, characteristics, and application scenarios of commonly used preference assessment methods, with the hope of providing valuable reference and lessons for domestic scholars to select and apply appropriate preference assessment methods in implementation research.

Primary biliary cholangitis (PBC) is a chronic cholestatic liver disease with unknown etiology, and patients with poor response to ursodeoxycholic acid and obeticholic acid may eventually progress to liver cirrhosis and even liver failure. Liver transplantation is the only effective treatment method for PBC at present. This article elaborates on liver transplantation, survival time after liver transplantation, complications, recurrence of PBC after liver transplantation, and prospects and challenges of liver transplantation in patients with PBC, so as to provide a reference for clinical outcome and treatment after liver transplantation for PBC.

Objective:To learn about the changing trend of iodine deficiency disorders (IDD) and the iodine nutrition level of key populations in Fuzhou.Methods:From March 2017 to October 2019, a cross-sectional survey method was used to carry out IDD monitoring among key populations in 12 counties (cities, districts) of Fuzhou. In each county (city, district), one township/street was selected from five directions: East, West, South, North and Middle. Forty non-boarding children aged 8-10 (age balanced, half male and half female) from one primary school and 20 pregnant women in each township/street were selected as the survey subjects. The edible salt samples and instant urine samples of children and pregnant women were collected to detect the contents of salt iodine and urinary iodine; the thyroid volume of children was measured by B-ultrasound, and the goiter rate was calculated.Results:From 2017 to 2019, a total of 7 479 edible salt samples were collected from children's homes, and the median salt iodine was 23.40 mg/kg, the coverage rate of iodized salt was 94.06% (7 035/7 479), the qualified rate of iodized salt was 97.70% (6 873/7 035), and the consumption rate of qualified iodized salt was 91.90% (6 873/7 479). A total of 3 602 edible salt samples were collected from pregnant women's homes, and the median salt iodine was 23.69 mg/kg, the coverage rate of iodized salt was 94.73% (3 412/3 602), the qualified rate of iodized salt was 97.66% (3 332/3 412), and the consumption rate of qualified iodized salt was 92.50% (3 332/3 602). A total of 7 479 urine samples were collected from children, and the median urinary iodine was 172.70 μg/L. A total of 3 602 urine samples were collected from pregnant women, and the median urinary iodine was 131.21 μg/L. A total of 7 479 cases of thyroid gland in children were examined, including 89 cases of goiter, and the goiter rate was 1.19%.Conclusions:The consumption rate of qualified iodized salt ( > 90%) of key populations, urinary iodine (100-< 200 μg/L) and goiter rate ( < 5%) of children in Fuzhou are all in line with the national standard for elimination of IDD, but pregnant women are at risk of iodine deficiency (urinary iodine < 150 μg/L).

Objective:To investigate the iodine nutrition status of key population in Fuzhou City, and to provide scientific basis for adjusting intervention strategies.Methods:From March to October 2021, a survey was conducted on iodine nutrition status of key population in 12 counties (cities, districts) of Fuzhou City. Each county (city, district) was divided into 5 sampling areas according to the east, west, south, north and middle directions. One township (street) was selected from each area, and 40 non-boarding children aged 8 - 10 (age balanced, half male and half female) from one primary school and 20 pregnant women (early, middle and late pregnancy balanced) were selected as survey subjects. Household salt samples and random urine samples were collected, and the salt iodine and urine iodine levels were tested by direct titration and arsenic and cerium catalytic spectrophotometry, respectively. Children's thyroid volume was measured by B-ultrasonography. At the same time, in cooperation with Fuzhou Maternal and Child Health Hospital, the thyroid stimulating hormone (TSH) testing results of heel blood of full-term natural delivery newborns in Fuzhou City in 2021 were collected.Results:A total of 2 400 children were monitored for salt iodine, urine iodine and goiter. The median salt iodine was 24.40 mg/kg, with an iodine salt coverage rate of 93.04% (2 233/2 400), a qualified rate of iodized salt of 97.40% (2 175/2 233), and a consumption rate of qualified iodized salt of 90.62% (2 175/2 400). The median urine iodine was 181.47 μg/L. The rate of goiter was 1.04% (25/2 400). A total of 1 200 pregnant women were monitored for salt iodine and urine iodine. The median salt iodine was 24.10 mg/kg, the coverage rate of iodized salt was 91.08% (1 093/1 200), the qualified rate of iodized salt was 97.90% (1 070/1 093), and the consumption rate of qualified iodized salt was 89.17% (1 070/1 200). The median urine iodine was 128.10 μg/L. The median TSH level in the heel blood of 14 242 newborns was 3.38 mU/L, and the proportion of TSH level > 5 mU/L was 30.96% (4 410/14 242).Conclusions:In 2021, children in Fuzhou City are at an appropriate level of iodine, but pregnant women are insufficient of iodine. We should continue to maintain comprehensive prevention and control measures mainly based on salt iodization, provide health education for pregnant women, and strengthen monitoring of TSH level in newborns.
