Objective To study the correlation between hyperinsulinemia (HIns) and arteriosclerosis in one community in Beijing. Methods Subjects who received arteriosclerosis screening in physical examination annually were studied. All subjects were received 75g oral glucose tolerance test (OGTT) to evaluate glucose metabolic level, and brachial-ankle pulse wave velocity (baPWV) examination to evaluate arteriosclerosis. The correlation between hyperinsulinemia and pulse wave velocity was analyzed. Results Among all the 1046 subjects under investigation, baPWV of subjects with HIns was higher than subjects with normoinsulinemia (NIns) in different glucose metabolism status [normal glucose tolerance, ( 1381.2 ±280. 8) cm/s vs ( 1280. 3 ±218. 7) cm/s; imparied glucose regulation, ( 1557. 5 ±319.3) cm/s vs (1474.7 ±305. 1) cm/s; diabetes, (1764.3 ±476.6) cm/s vs (1664.2 ±374.6)cm/s], especially in subjects with normal glucose tolerance ( P < 0.01 ). The prevalence of cardiovascular risk factors in subjects with HIns was much higher than subjects with NIns ( P < 0.01 ). Multiple logistic regression analysis showed that hyperinsulinemia was the risk factor of arteriosclerosis, and the OR (95%CI) of subjects with HIns was 1.91 (1. 169-3. 105, P <0.01 ) as compared to the subjects with NIns. Conclusion The subjects with HIns suffered from much more metabolic risk factors than NIns.Hyperinsulinemia that closely correlated with baPWV was a risk factor of arteriosclerosis.

ObjectiveTo explore the role of BTBD10 overexpression in the proliferation of insulinoma cell line INS-1and its mechanism. MethodsThe recombined expression plasmid of pcDNA4.0-BTBD10 was constructed by gene cloning technique and was transfected into INS-1 cell by lipofectamine 2000. The stable overexpression BTBD10 of INS-1cell was selected at 48th hour after transfection.INS-1 cell proliferation activity was measured by MTT method.The expression of BTBD10,protein kinase B(Akt),phospho-Akt(p-Akt),mammal target of rapamycin (mTOR) and phospho-mTOR (p-mTOR) were determined by Western blot.ResultsThe stable overexpression BTBD10 of INS-1 cell wassuccessfullyconstructed.OverproductionofBTBD10promotedbetacellproliferation.The phosphorylation of Akt and mTOR was increased and the ratio of p-Akt/Akt and p-mTOR/mTOR was enhanced in the INS-1 overexpressed by BTBD10.But the expression of total Akt and mTOR presented no obvious changes. Conclusion The overexpression BTBD10 of INS-1 cell could activate of Akt/mTOR signalling pathway via stimulating phospho-mTOR and Akt,and enhance overall cell protein translation,so as to promote proliferation of INS-1 cell.

This study was aimed to observe the regulating effect of Shen-Xiong Hua-Y u (SXHY) capsule precondi-tioning on the expression of subtypes of nitric oxide synthase (NOS), including endothelial nitric oxide synthase (eNOS), nervous nitric oxide synthase (nNOS), inducible nitric oxide synthase (iNOS), in cerebral ischemia-reperfu-sion injury (CIRI) among rats, and to further clarify the mechanism of protective effect by SXHY capsule on acute CIRI rats. Rats were randomly divided into the sham operation group, CIRI group, and SXHY capsule of high-, medium-, and low-dose preconditioning group (480, 240, 120 mg·kg-1). Each group was further randomly divided into different subgroups, which were the 3, 6, 12, 24, 48, 72 h group after 2 h CIRI (n=6). Intragastric administration was given once a day for 7 days. The middle cerebral artery occlusion (MCAO) and reperfusion model was repro-duced by an intraluminal filament method on the 7th day. The protein expressions of eNOS, nNOS and iNOS were measured by immunhistochemical method. The results showed that compared with the sham operation group, expres-sions of eNOS, nNOS and iNOS in the CIRI group were increased at different time points (i.e., 3, 6, 12, 24, 48, 72 h, P< 0.05 or P< 0.01). Compared with the CIRI group, eNOS expression increased at different time points in SX-HY capsule group (P< 0.05 or P< 0.01). The nNOS and iNOS expression decreased at different time points (P<0.05 or P < 0.01). Among them, the high-dose group was the group with the most obvious effect. It was concluded that SXHY capsule preconditioning had protective effect on CIRI. Its mechanism may be related to the regulation on protein expression of NOS subtypes.

Objective:To understand the current status of subjective symptoms and self-management efficacy in patients with chronic rhinosinusitis and nasal polyps after endoscopic sinus surgery, and analyze the correlation between the two.Methods:This study was a cross-sectional study. From July 2018 to June 2020, a total of 228 patients with chronic rhinosinusitis and nasal polyps who underwent endoscopic sinus surgery in a ClassⅢ Grade A hospital in Beijing were selected as the research object. The survey was conducted using the General Information Questionnaire, Visual Analogue Scale (VAS) , and Chronic Disease Self-Efficacy Scale (CDSES) . Pearson correlation and Spearman rank correlation were used for the correlation analysis.Results:Among 228 patients with chronic rhinosinusitis and nasal polyps, there were still 184 cases (80.70%) of nasal congestion, 134 cases (58.77%) of runny nose, 116 cases (50.88%) of olfactory symptoms, 112 cases (49.12%) of head and face pain symptoms, and 208 cases (91.22%) of general discomfort. Among 228 patients with chronic rhinosinusitis and nasal polyps, the symptom management self-efficacy dimension in CDSES score was (6.19±1.04) , and the disease common management self-efficacy dimension score was (7.42±0.95) , and there were 32 cases with a total score of ≥7, accounting for 14.04% (32/228) . The VAS score of various subjective symptoms was negatively correlated with the total score of CDSES and the score of each dimension, and the difference was statistically significant ( P<0.05) . Conclusions:Patients with chronic rhinosinusitis and nasal polyps still have disease symptoms after endoscopic sinus surgery, and the self-management efficacy needs to be further strengthened. Clinical nurses should pay attention to subjective symptoms of these patients after surgery, teach them how to manage disease symptoms, and improve the patient's self-management efficacy.

Objective:
To explore the relationship between childhood maltreatment and suicide ideation of college students,so as to provide basis for physical and mental health of college students.
Methods:
Students from 6 universities in Shanxi Province(3 854 college students provided eligible questionniare for childhood abuse and 3 882 for suicidal ideation) were selected by multi-stage random cluster sampling from May to July 2018, the Chinese Version of the Childhood Trauma Questionnaire and the Self-rating Idea of Suicide Scale were used in the survey.
Results:
Of all subjects,42.4% had at least one kind of abuse experience in childhood and 3.9% had suicidal ideation in the past week. By chi square test,the detection rate of suicidal ideation of college students who suffered physical abuse,emotional abuse,sexual abuse,physical neglect,emotional neglect in childhood was higher than that of college students without maltreatment (χ2=13.78,12.97,17.10,56.56,66.58,P<0.01);Spearman correlation analysis showed that there was a positive correlation between each type of maltreatment in childhood and college students’ suicidal ideation(r=0.06,0.06,0.07,0.12,0.13,P<0.01);Multivariate Logistic regression model found that after controlling other influencing factors,physical neglect and emotional neglect in childhood were independent risk factors for suicide ideation of college students (OR=2.18,2.07,P<0.05).
Conclusion
Physical neglect and emotional neglect in childhood can increase the risk of college students’ suicidal ideation. Paying enough attention and care to them in early childhood may help to prevent their suicidal ideation in adulthood.

Objective:To detect the expression levels of laboratory of genetics and physiology 2 (LGP2), retinoic acid inducible gene I (RIG-I) and melanoma differentiation associated gene 5 (MDA5) in children with hand, foot and mouth disease (HFMD), and to explore their possible clinical significance in HFMD.Methods:Fifty children with HFMD, who visited Second Affiliated Hospital of Xi′an Jiao Tong University, Xi ′an Children′s Hospital and Xi ′an Central Hospital from May 2020 to May 2021, were selected as the research subjects, and 20 children with physical examination at the same age during the same period were selected as the control group.Children with HFMD were divided into enterovirus 71 (EV-A71) type and coxsackievirus A6 (CV-A6) type according to the results of pathogen detection, and then divided into mild group and severe group according to the severity of the disease.The relative mRNA expression levels of LGP2, RIG-I and MDA5 in each group, and the correlation among the three proteins were compared and analyzed.Results:Among 50 cases of HFMD, 26 cases were EV-A71 type (16 cases were mild and 10 cases were severe) and 24 cases were CV-A6 type (17 cases were mild and 7 cases were severe). There was no significant difference in age and sex between HFMD group and control group ( P>0.05). The relative expression levels of LGP2 mRNA in EV-A71 and CV-A6 HFMD cases were 2.37(1.78, 3.25)% and 1.88 (1.35, 3.13)%, lower than that in control group [2.97(2.61, 3.55)%]. Only the difference between CV-A6 HFMD children and control group was statistically significant ( Z=-2.310, P=0.021). The relative expression levels of RIG-I mRNA in EV-A71 and CV-A6 HFMD cases were 9.95 (7.79, 14.62)% and 9.78(7.04, 15.83)%, lower than that in control group [18.47(13.00, 21.07)%]. The differences were all statistically significant ( P<0.05). The relative expression levels of MDA5 mRNA in EV-A71 and CV-A6 HFMD cases were 4.41(2.82, 5.99)% and 3.98 (2.18, 7.41)%, lower than that in control group [5.10(3.52, 7.71)%], but the differences were not statistically significant.There were no significant differences in the relative expression levels of the three indicators between the mild and severe groups of children with EV-A71 or CV-A6 HFMD.The expression levels of LGP2, RIG-I and MDA5 mRNA were highly correlated( P<0.001). Conclusion:The relative expression levels of LGP2, RIG-I and MDA5 mRNA in children with HFMD are decreased in different degrees than those in normal children.And there is a correlation among them.
