BACKGROUND: The prevalence of obesity and the related factors may be different among different nationalities, and different types of obesity have different influence on cerebrovascular and cardiovascular diseases.OBJECTIVE: To investigate the characteristics and related factors of obesity in Korean and Han populations in rural Yanbian.DESIGN: A randomized controlled observation.SETTING: Antu County Hospital of Jilin Province.PARTICIPANTS: The survey was carried out in 4 towns of Tumen city and Antu county in Yanbian area from August 2004 to August 2005. Totally 1 786 Korean and Han residents above 30 years old were randomly selected, the proportion of nationalities in each area was close. In order to accurately compare the prevalence of obesity among different nationalities, family members of mixed blood were excluded, as well as patients with severe cardiovascular disease and other organic diseases. Informed contents were obtained from all the subjects.METHODS: The information related to this survey was collected by means of home visit and physical examination in the selected community and health center. All the investigators were strictly trained to standardize the contents, procedure and methods before the survey. Related information was collected by means of face-to-face inquisition with uniform questionnaire. ② All the examinees accepted the physical examination in the morning under fasting and resting states by uniform device and examiners. The physical examination included measurements of body height, body mass, waistline,hip circumference, blood pressure. Fasting venous blood (2 mL) was collected to determine serum levels of total cholesterol, triglyceride, high density lipoprotein-cholesterol (HDL-C) and fasting plasma glucose with automatic biochemical analyzer. ③The crude prevalence rate was calculated. The age adjusted prevalence rate was calculated directly by using the sample survey data of Yanbian Korean National Minority Autonomous Prefecture in 2000. ④ The enumeration data were compared with the Chi-square test and u test.MAIN OUTCOME MEASURES: Prevalence and related factors of different types of obesity between different nationalities.RESULTS: ① The age adjusted prevalence was 19.9% and 24.7% in Korean and Han males respectively, whereas 26.3% and 29.7% in females, and it was obviously higher in Han than in Korean population (P < 0.01). The age adjusted prevalence of abdominal obesity, taking waist-to-hip ratio as the diagnostic standard, was 33.9% and 31.6% in Korean and Han males respectively, whereas 53.4% and 51.1% in females, and it was obviously higher in Korean than in Han for both males and females (P < 0.01). The age adjusted prevalence of abdominal obesity, taking waistline/body height ratio as the diagnostic standard, was 48.8% and 44.0% in Korean and Han males respectively, whereas 63.7% and 60.3% in females, and it was obviously higher in Korean than in Han for both males and females (P < 0.01). ② The prevalence of hypertension, hyperglycemia, low HDL-C and metabolic syndrome were markedly higher in Korean than in Han for both males and females (P< 0.01); The prevalence of hypertriglycerdemia, smoking and drinking rates were obviously higher in Korean males than in Han ones (P < 0.01); The smoking rate was markedly higher in Han females than in Korean ones (P < 0.01). ③ The occurrences of different types of obesity were associated with hypertension,hyperglycemia, low HDL-C, hypertriglyceridemia and metabolic syndrome in both Korean and Han population.CONCLUSION: ① The different types of obesity and the distribution of influencing factors are different between Korean and Han population in rural Yanbian. ② Different types of obesity are all associated with hypertension, hyperglycemia,low HDL-C, hypertriglyceridemia, metabolic syndrome.

Objective To observe the impacts of sulforaphane on proliferation, apoptosis and Wnt/β-catenin pathway of cultured retinoblastoma cells. Methods Retinoblastoma Y79 cells were cultured with varying concentrations of sulforaphane (10, 20, 40 mg/L) for 24 and 48 h. Cell proliferation and apoptosis were measured by CCK8 assay and flow cytometry. Apoptosis related proteins Bax and Bcl-2, as well as the expression levels of related proteins in Wnt/β-catenin signaling pathway were determined using Western Blot. Results Sulforaphane suppressed cell proliferation and stimulate apoptosis (12.47% ± 2.24%, 24.63% ± 3.44%, 57.49% ± 5.41% vs. 3.47% ± 0.74%) in a dose- and time-dependent manner, respectively. Furthermore, 40 mg/L of sulforaphane increased the expression of Bax (0.57 ± 0.03 vs. 0.12 ± 0.01), but decreased the Bcl-2 (0.16 ± 0.01 vs. 0.81 ± 0.03) protein expression. The results of Western Blot displayed that sulforaphane decreased the expression levels of Wnt (0.19 ± 0.01 vs. 0.74 ± 0.02), β-catenin protein (0.22 ± 0.02 vs. 0.82 ± 0.03), indicating that sulforaphane can inhibit the activation of Wnt/β-catenin signaling pathway. Conclusions The sulforaphane could inhibit the proliferation and induce the apoptosis of retinoblastoma Y79 cells, probably regulating by the Wnt/β-catenin signaling pathway.

Objective:To investigate the application of magnetic resonance imaging (MRI) in clinical staging and classification of adult Japanese encephalitis.Methods:The clinical data and craniocerebral MRI findings of 35 adult patients with Japanese encephalitis admitted in General Hospital of Ningxia Medical University from August to September 2018 were analyzed retrospectively. The MRI imaging characteristics were compared among patients with different stages and types, the apparent diffusion coefficient (ADC value) of thalamic lesions in patients of different stages was analyzed. SPSS 23.0 software was used to analyze the data.Results:Six moderate cases all had lesions involving the thalamus, and the number of intracranial lesions was <2. In 11 severe cases, 8 had lesions involving thalamus and 5 had lesions involving hippocampus; the number of intracranial lesions was <2 in 3 cases, the number of intracranial lesions was 2-4 in 3 cases, and the number of intracranial lesions was >4 in 5 cases. In 18 cases critical cases, the lesions involved thalamic in 14 cases, hippocampus in 14 cases, cerebral cortex in 14 cases, cerebral feet in 9 cases, basal ganglia area in 6 cases, and brain stem in 2 cases, respectively; 2 cases had the intracranial lesions <2, 6 cases had intracranial lesions 2-4, 10 cases had intracranial lesions >4. In 11 preliminary stage patients, 9 cases had DWI high signal and 2 had FLAIR slightly high signal; in 19 extreme stage patients, 16 cases had DWI high signal, 11 cases had FLAIR slightly high signal, 3 cases had T1WI high signal and 6 cases had T2WI high signal. In 5 recovery stage patients, 1 case had DWI slightly high signal, 5 cases had FLAIR high signal, and 1 case had T2WI high signal. The ADC values of thalamic lesions in recovery and extreme patients were higher than those in the preliminary stage ( q=3.931 and 4.012, P<0.05). The ADC value of thalamic lesions in the recovery period was higher than that in the extreme period ( q=3.372, P<0.05). Conclusions:The number of lesions and the range of involvement are associated with disease severity in adult Japanese encephalitis. The DWI sequence is easy to detect at early stage, and the FLAIR sequence shows a long time span of lesions; and the DWI and FLAIR sequences are of great significance for the early clinical staging and classification of adult encephalitis patients. At the same time, the ADC value shows a trend of disease progresses, which can be used as a supplement for the clinical staging in adult encephalitis patients.

Objective:To evaluate the efficacy and safety of enteral extended biliary stenting for biliary stricture.Methods:A multicenter retrospective cohort study was conducted on data of 550 patients with obstructive jaundice due to extrahepatic bile duct stricture between February 2006 and April 2020. Patients were assigned to conventional group (undergoing conventional biliary stent placement) and extended group (undergoing enteral extended biliary stent placement). Propensity score was used to match the basic data of patients of the two groups. Then the stent patency time, bilirubin difference before and after 1 week operation, incidence of complications and hospital stay were compared between the two groups.Results:Among the 550 patients, clinical data of 20 cases were missing and 35 failed to be followed up. Finally, 326 patients were enrolled to the study after propensity score matching with 163 cases in each group. The patency time of extended group was 111.0 (82.0, 192.0) days, which was longer than that of conventional group with patency time of 93.0 (70.0, 141.8) days ( Z=3.260, P=0.001). Total bilirubin difference value of pre-operation and post-operation was less in extended group [51.2 (26.0, 114.7) μmol/L VS 46.0 (13.9, 81.1) μmol/L, Z=2.095, P=0.036]. The rate of early adverse events [4.3% (7/163) VS 3.7% (6/163), P=0.079] and median in-patient days (10.0 days VS 10.0 days, P=0.379) were similar in the two groups. Conclusion:Enteral extended biliary stent is effective and safe for treatment of biliary stricture, which can prolong the patency time without increasing postoperative complications and hospital stay.

ObjectiveTo prepare oral nanoemulsions encapsulating essential oil from Alpinia zerumbet fructus(EOFAZ) and to investigate its pro-absorption effect in vitro and distribution in vivo. MethodThe proteoglycan conjugate polysaccharides of vinegar-processed Bupleuri Radix-bovine serum albumin(VBCP-BSA) was prepared by Maillard reaction of VBCP and BSA. Taking VBCP-BSA as emulsifier, vitamin B12(VB12) as absorption enhancer, and medium chain triglycerides mixed with EOFAZ as oil phase, the nanoemulsions loaded with EOFAZ was prepared by high energy emulsification method. The particle size, particle size distribution, surface Zeta potential, EOFAZ content and appearance and morphology of the nanoemulsions were characterized, and fluorescein tracer method was used to investigate the absorption effect of fluorescein-labeled EOFAZ nanoemulsions in vitro and their distribution in vivo. ResultVBCP-BSA was formed by Maillard reaction for 48 h with high grafting rate. Using VBCP-BSA as emulsifier, the homogeneous pink nanoemulsions was prepared and denoted as EOFAZ@VBCP-BSA/VB12. The particle size of the nanoemulsions was less than 100 nm and the particle size distribution was uniform. The surface of the nanoemulsions was a weak negative charge, and the shape was spherical. The encapsulation rate of the nanoemulsions for EOFAZ was greater than 80%, which had a good absorption effect in vitro and could enhance liver accumulation after oral administration. ConclusionThe designed proteoglycan nanoemulsions can effectively load EOFAZ, promote oral absorption and enhance liver distribution, which can provide experimental basis for the development of oral EOFAZ liver protection preparations.
