Objective To evaluate the impact of the eastern healthy diet pattern (EHDP) on body weight, blood pressure, blood lipids, and glucose in type 2 diabetes mellitus (T2MD) patients and compare it with the effect of traditional diabetes diet (TDD). Methods A total of 140 inpatients with T2DM admitted to Chenzhou First People's Hospital from May 2022 to December 2022 were selected and randomly assigned to EHDP (n = 70) group or TDD group (n = 70). Both groups were served with three meals a day by the dietitian department of the hospital for 8 weeks. The TDD group followed the guidelines of the Chinese diabetes society, while the EHDP group optimized diversified food intake and increased aquatic products, olive oil, and dairy products. Results There was no statistically significant difference between the two groups of patients in baseline data including age, gender, blood pressure, blood glucose, and hypoglycemic and lipid-lowering treatment between the two groups (P value 0.238~0.795). After 8 weeks of dietary intervention, compared with before the intervention, the body weight, fasting blood glucose, 2-hour postprandial blood glucose, glycosylated hemoglobin, blood lipids and blood pressure of both groups showed statistically significant decreases (P<0.05). The reductions in weight, BMI, blood lipids, blood pressure and fasting blood glucose in the EHDP group were greater than those in the TDD group (P<0.05). Conclusion EHDP is better than the traditional diabetic diet in reducing blood glucose, weight, blood pressure, and blood lipids compared to traditional diets. Both diet patterns effectively improve 2h PG and HbA1c with no significant difference.

@#Abstract: Objective To understand the density changes and seasonal fluctuation of larvae and adults of Aedes albopictus in Hainan Province from 2017 to 2021, and to provide a scientific basis for the prevention and control of dengue fever and other vector-borne diseases in Hainan Province. Methods The Breteau index method was used to monitor the larvae of Aedes mosquitoes, and the breeding sites of all small indoor and outdoor water containers and their larvae was checked and recorded. The adult mosquitoes were monitored by double lamination and light trap. Results A total of 1 962 adult female Aedes albopictus mosquitoes were captured in Hainan Province from 2017 to 2021, accounting for 2.17% of the total captured mosquitoes. There were significant differences in mosquito species composition in different habitats in different years (χ2=312.258, P<0.01). In 2017, the density of mosquitoes in livestock sheds was the highest (9.71 per lamp·night), but the composition ratio of Aedes albopictus was the lowest (1.29%). In 2020, the mosquito density in hospitals was the lowest (2.22 mosquitoes per lamp·night), and in 2019, the proportion of Aedes albopictus in residential areas and hospitals was the highest (3.27% on average).The mosquito density in different habitats was the lowest in 2020. The proportion of Aedes albopictus in residential areas and livestock sheds showed an increasing trend from 2017 to 2021, while the proportion of other habitats showed significant fluctuations. The proportion of Aedes albopictus in hospitals showed an obvious decreasing trend in 2020. From 2017 to 2021, the average mosquito density was 5.97, 4.26, 3.82, 3.39 and 3.68 mosquitoes per lamp·night, respectively, showing a decreasing trend year by year except 2021. Except for 2019, the lure index also showed a decreasing trend, with an average value of 1.5/(hour·net), showing a decreasing trend year by year. From 2017 to 2021, the annual average density of Aedes albopictus in Hainan Province was 0.09 mosquitoes per lamp·night, showing obvious seasonal fluctuation. The Breteau index showed a slow decline from 2017 to 2021, and its annual peak was between June and August, which was 1-2 months later than the peak of adult mosquito density. Conclusions The population density of Aedes albopictus in Hainan shows obvious seasonal characteristics. Mosquito control activities should be carried out according to the seasonal characteristics of mosquitoes to reduce the risk of dengue fever and other infectious diseases.

Objective:To systematically evaluate the correlation between C-reactive protein (CRP) and postmenopausal osteoporosis.Methods:PubMed, EMbase, Cochrane library, China biomedical literature database, China HowNet and Wanfang database were searched by computer to collect the clinical research literature related to CRP and postmenopausal osteoporosis. The retrieval period was from the establishment of the database to April 1, 2021. The two researchers screened the literature according to the inclusion and exclusion criteria, extracted the data and evaluated the quality, Revman5.3 software was used for meta-analysis.Results:A total of 12 studies were included, including 778 cases in postmenopausal osteoporosis group and 933 cases in non osteoporosis group. The results of combined analysis showed that the level of CRP in postmenopausal osteoporosis group was higher than that in non osteoporosis group, and the difference was statistically significant (standardized mean difference (SMD)=0.55, 95% CI (0.03, 1.07), P=0.04). Further subgroup analysis according to different grouping criteria and CRP detection methods showed that the level of CRP in patients with osteoporosis was higher than that in normal bone group ( SMD=0.88, 95% CI (0.07,1.69), P=0.03). There was no significant difference in CRP level between osteoporosis group and osteopenia Group (SMD=0.13, 95% CI (-0.05, 0.31), P=0.15). There was no correlation between CRP levels detected by automatic analyzer, chemiluminescence immunoassay and enzyme-linked immunosorbent assay and postmenopausal osteoporosis. The level of CRP in postmenopausal osteoporosis group detected by immunoturbidimetry was higher than that in non osteoporosis group (SMD=1.50, 95% CI (1.10,1.90), P<0.01). Conclusion:CRP level is related to postmenopausal osteoporosis. High CRP level may be a risk factor for postmenopausal osteoporosis.

BACKGROUND: With the increasing aesthetic pursuit of patients, an aesthetic abutment with certain strength has aroused people's attentions either in the anterior or posterior tooth repair. OBJECTIVE: To evaluate the effects of titanium abutment and zirconia abutment on peri-implant tissue in anterior teeth.METHODS: A total of 40 anterior teeth from 34 patients were selected and received single crown restoration with Ankylos implants. Among them, titanium abutments were used in 20 teeth, and zirconia abutments in the other 20 teeth. All the patients were re-visited at 12 months after crown restoration. Peri-implant marginal bone resorption length (MBL), periodontal probing depth (PD), modified plaque index (mPLI), modified sulcus bleeding index (mSBI), and papilla index (PP) were detected; patient satisfaction investigation was carried out; and aesthetic assessment was done based on the pink esthetic score (PES).RESULTS AND CONCLUSION: There were no differences between two groups in MBL, PD, mPLI, mSBI, PP. Patients in both groups were satisfied with the treatment outcomes with insignificant difference (P > 0.05). The PES value in the zirconia abutment group was significantly higher than that in the titanium abutment group (P < 0.05). Overall, titanium and zirconia abutments show the similar effects on the peri-implant tissues and both can achieve good clinical outcomes. However, zirconia abutments have certain advantages in the aesthetic restoration for anterior teeth, and further investigation on long-term effects is warranted.

<p><b>OBJECTIVE</b>To explore the effects of chronic exposure to trace chromium (VI) as a result of metal-on-metal hip arthroplasty on oxidative stress in mouse liver cells.</p><p><b>METHODS</b>Eighty NIH mice were randomly divided into 4 groups and subject to intraperitoneal injection of CrO(3) at the dose of 0, 5, 10 or 20 mg/kg every other day for 16 weeks. Five mice from each group were selected every 4 weeks for determining the content of chromium (VI) in the whole blood and the levels of reactive oxygen species (ROS), malondialdehyde (MDA), glutathione (GSH), glutathione reductase (GR) activity, and glutamate cysteine ligase (GCL) expression in the liver cells. The ultrastructural changes of the liver cells were also observed using transmission electron microscopy.</p><p><b>RESULTS</b>Exposure to 5 and 10 mg/kg CrO(3) caused significantly increased blood chromium concentration and ROS level, which reached the peak level at 8 weeks and became stabilized, whereas at the dose of 20 mg/kg, CrO(3) exposure resulted in progressive, time-dependent increase of blood chromium concentration and ROS level. MDA showed no significant changes in the 4 groups. With the prolongation of the exposure time, GSH content and GR activity were decreased in these groups. In 5 and 10 mg/kg CrO(3) groups, GCL expression increased at each time point of measurement, but in 20 mg/kg group, GCL expression decreased gradually with a prolonged exposure. Transmission electron microscopy revealed apoptotic changes of the liver cells in 20 mg/kg group.</p><p><b>CONCLUSION</b>The slow accumulation of trace chromium (VI) after metal-on-metal hip arthroplasty may cause oxidative stress and changes in the oxidative stress system in the liver cells.</p>
