Objective:To evaluate the short-term economic effects of four kinds of premixed insulin in newly diagnosed type 2 dia-betes mellitus. Methods:A total of 120 newly diagnosed patients with type 2 diabetes mellitus were divided into four groups according to the kind of premixed insulin, group A was treated with insulin aspart 30 injection, group B was treated with insulin lispro 25 injec-tion, group C was treated with isophane protamine biosynthetic human insulin injection and group D was treated with protamine zinc re-combinant human insulin injection. The course of treatment was three months. The therapy efficacy was assessed by the remission rate in three months. The short-term economic effect was evaluated by the cost-minimization analysis method. Results:The remission rate of group A, B, C and D respectively was 48. 39%, 48. 28%, 51. 61% and 51. 72% without significant difference (P>0. 05). The average cost per person of the four groups was 1195. 52, 1202. 41, 1220. 69 and 1258. 84 yuan, and the average medicine cost per person was 750. 52, 689. 41, 754. 69 and 764. 34 yuan, respectively. There was no significant difference in cost among the four groups (P >0. 05). Conclusion:All the four kinds of premixed insulin can be used for the starting treatment with the similar total cost, and in relative terms, aspart 30 injection and insulin lispro 25 injection are better for the initial treatment of diabetes.

Objective: To observe the effects of recombinant adenovirus TRAIL (AdS-TRAIL & Ad5F35-TRAIL) on apoptosis of non-small cell lung (NSCLC) cells, so as to assess the value of Ad-TRAIL in gene therapy of NSCLC. Meth-ods: CAR and CD46 expression levels in lung cancer cell lines (A549, Z793, QG56 and NCI-H520) and the primary lung cancer cells from samples of 10 NSCLC patients were assayed by flow cytometry analysis. The lung cancer cell lines and primary lung cancer cells were infected with Ad5-TRAIL & Ad5F35-TRAIL adenoviral vectors at MOI 10 or 50, re-spectively; the percentage of apoptosis cells labeled by Annexin V-FITC in different cells were measured by flow cytometry 48 h after transfection. Results: The expression of CD46 were higher than that of CAR in all the lung cancer lines (A549, Z793, QG56 and NCI-H520) and the primary lung cancer cells. Significant apoptosis was observed in Z793 and QG56 cells transfected with Ad5-TRAIL or Ad5F35-TRAIL at MOI 10, with the apoptosis rate being (1.76±2.10)% (Ad5-TRAIL), (15.96±2.89) % (Ad5F35-THAIL) and (6.05±1.58) % (Ad5-TRAIL), (10.11±1.26) % (Ad5F35-TRAIL), respectively, compared to no adenovirus-transfected cells ([2.33±0.37] % and [5.95±1.89]%, respectively, P < 0.05). Less than 10% of apoptosis cells were detected in NCI-H520 cells transfected with Ad5- or Ad5F35-TRAIL at MOI 50 ([12.89±3.2] % for AdS-TRAIL and [9.08±1.35]% for Ad5F35-TRAIL, respectively) compared to no adenovirus-transfected cells ([7.04±2.17] %, P > 0.05). Moreover, apoptosis induced by Ad5- or Ad5F35-TRAIL transfection in A549 cells was not detected both at MOI 10 and 50. About half of the primary lung cancer cells from 10 patients induced apoptosis after transfected with Ad5-TRAIL or Ad5F35-TRAIL vector. A higher percentage of apoptotic cells were found in Ad5F35-TRAIL group than those in Ad5-TRAIL and control groups. Conclusion: Ad5-TRAIL can induce apoptosis of NSCLC cells in vitro, and Ad5F35-TRAIL is more potent than Ad5-TRAIL, so Ad5F35-TRAIL is more suitable for gene therapy of NSCLC.

Objective To observe the clinical effect ofJiedu-Huayu granule for the Dengue Fever (DF).Methods The patients with DF were randomly divided into the treatment group and control group. Both groups received the conventional treatment, and the treatment group addedJiedu-Huayu granule. The clinical effects were detected.Results At the baseline, the ALT and AST in the treatment were significantly higher than those in the control group (t=2.830,P=0.014;t=2.109,P=0.044). But after treatment, there was no difference between groups. The ALT in the treatment group showed a gradual change and AST recovery time showed short. Compared with control group, the concentration of sVCAM-1 in the treatment group was higher at baseline and the third day (t=2.780,P=0.018;t=2.130,P=0.460), but the concentration of MCP-1 desceased significantly on the 6th day (t=-2.164,P=0.042).Conclusions Compared with the western medicine, the treatment of western medicine andJiedu-Huayu granule could alleviate liver injure, shorten the recovery time, and reduce the concentration of sVCAM-1 and MCP-1.

Objective:To explore the reliability and validity of the community commitment scale (CCS) in community-dwelling elderly people.Methods:From May to August in 2020, a total of 526 community-dwelling elderly were investigated by community commitment scale, community's self-efficacy scale for preventing social isolation (CSES). SPSS 25.0 and AMOS 22.0 softwares were used to analyze the reliability and validity.Results:The overall Cronbach's α coefficient of the community commitment scale was 0.818, and the Cronbach's α coefficients of social and belonging dimensions were 0.750 and 0.777, respectively. The Guttman split-half reliability coefficients were 0.799-0.835, and the test-retest reliability was 0.802. Each item-to-total score correlations were 0.614-0.753 (all P<0.05). The item level content validity index (I-CVI) was 0.830-1.000, the scale level content validity index (S-CVI/UA) was 0.875, and the average content validity index (S-CVI/Ave) was 0.972. Two common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 57.019%. The confirmatory factor analysis all indicators reached the adaptation standard (χ 2/ df=2.638, RMSEA=0.079, GFI=0.957, AGFI=0.918, TLI=0.936, CFI=0.956, IFI=0.957), and standardized regression coefficients were 0.63-0.80.

OBJECTIVETo investigate the effect of adrenomedullin (ADM) on renal arteriole remodeling and phosphorylation of extracellular signal-regulated protein kinases 1/2 (p-ERK1/2) in spontaneous hypertensive rats (SHR).

METHODSMale SHR (4 weeks old) were randomized into hypertensive group (SHR) and ADM-treated group (ADM) to receive subcutaneous saline and ADM injections (daily dose of 1.0 nmol/kg, 5 days a week), respectively, with age-matched Wistar-Kyota (WKY) rats as the blank control. The systolic blood pressure (SBP) was measured at the end of each week, and histological changes of the renal arterioles were observed using HE and Weigert staining; the expression of P-ERK1/2 in the arterioles was detected with immunohistochemistry and Western blotting.

RESULTSAt 16 and 24 weeks of age, the rats in both SHR and ADM groups showed significantly higher SBP levels than WKY rats (P<0.05), and at 24 weeks, SBP was significantly lower in ADM group than in SHR group (P<0.05). The intima thickness/lumen diameter (IT/LD) ratio of the renal arterioles increased in both SHR and ADM groups at 16 and 24 weeks as compared with that of WKY rats (P<0.05), and for arterioles with an outer diameter <40 µm, the IT/LD ratio was significantly lower at 24 weeks in ADM group than in SHR group (P<0.05). The renal expression of p-ERK1/2, which increased significantly in SHR and ADM groups at 16 and 24 weeks (P<0.05), was significantly lower in ADM group than in SHR group at 24 weeks (P<0.05).

CONCLUSIONSLong-term ADM treatment can control SPB elevation in SHR rats and reduce renal arteriole remodeling by inhibiting the phosphorylation of ERK1/2.

Objective:To explore the relationship between self-perceptions of aging and cognitive function, and the mediating and moderating effect of loneliness among them.Methods:A multi-stage stratified sampling was conducted in Jinzhou from September to November 2021, and 318 community-based elderly were included.General data questionnaire, the brief ageing perceptions questionnaire (BAPQ), UCLA loneliness scale(UCLA-LS) and mini-mental state examination (MMSE) were applied to all subjects.IBM SPSS 25.0 software was used to conduct independent sample t-test, analysis of variance and Pearson correlation analysis, and Bootstrap program of AMOS 22.0 was used to analyze the mediation effect.The model in SPSSAU on-line analysis program was used to test the moderating effect. Results:The average scores of self-perceptions of aging, loneliness and cognitive function were (44.85±12.48), (41.70±8.73) and (24.87±3.40) respectively.And 65 of 318 subjects had cognitive impairment, and the detection rate was 20.44%(65/318). Self-perceptions of aging, loneliness and cognitive function scores were significantly correlated between each other(all P<0.05). Self-perceptions of aging had a negative effect on cognitive function ( β=-0.467, P<0.01). Self-perceptions of aging had a positive effect on loneliness ( β=0.585, P<0.01). Loneliness had a negative effect on cognitive function ( β=-0.234, P<0.01). The indirect standardization effect of loneliness between self-perceptions of aging and cognitive function was -0.137, and the mediating effect accounted for 22.68% of the total effect.Loneliness played a moderating role between self-perceptions of aging and cognitive function ( β=-0.114, t=-2.26, P=0.025). Conclusion:Self-perceptions of aging and loneliness can predict the cognitive function in the elderly, and loneliness plays a mediating role between self-perceptions of aging and cognitive function.Early detection of negative senility emotion and loneliness of the elderly will play a positive role in preventing the occurrence of cognitive impairment.

Objective To explore the relationship between the increase of transmural dispersion of repolarization with ventricular arrhythmia,myocardial infarction degree and coronary events in elderly patients with myocardial infarction at T peak-T end interval in order to provide the guidance instruction for the assessment of prognosis of elderly myocardial infarction.Methods One hundred and twenty cases of senile myocardial infarction in the cardiology department of our hospital were selected,including 73 males and 47 females,the average age was (62.37 ± 11.34) years old.In addition,76 elderly cases of other heart disease were selected as the control group,including 42 males and 34 females,the average age was (59.56 ± 12.64) years old.The T peak-T end interval,dispersion and T peak-T end interval and dispersion after correcting the heart ratein different groups were analyzed.Results The T peak-T end interval,dispersion and T peak-T end interval and dispersion after correcting the heart rate had statistical differences between the control group and AMI group at admission and between the acute stage and recovery stage in the AMI group (P＜0.01);the T peak-T end interval and dispersion before and after correcting the heart rate had statistical differences among the patients with different ventricular arrhythmia (P＜0.01);the T peak-T end interval and dispersion before and after correcting the heart rate had statistical differences among the patients with anterior lateral wall,anterior wall,inferior wall,high lateral wall and multiple vessels infarction (P＜0.01);the case death after correcting the heart rate in different degrees and coronary event occurrence at admission had statistical difference (P＜0.01).Conclusion The T peak-T end interval has a close relation with malignant arrhythmia occurrence,which has an important predictive value for the short term prognosis in elderly patients with AMI.

The American Association for the Study of Liver Diseases (AASLD) updated and published the Practice Guidance for the Diagnosis and Management of Nonalcoholic Fatty Liver Disease (NAFLD) in July 2017, which provides recommendations for the accurate diagnosis, treatment, and effective prevention of NAFLD. Related metabolic diseases should be considered during the initial evaluation of patients suspected of NAFLD. Noninvasive diagnostic techniques including transient elastography, magnetic resonance elastography, and serum biochemical models should be used to evaluate the development and progression of liver fibrosis in patients with NAFLD. Clinical liver pathology report should clearly differentiate between nonalcoholic fatty liver (NAFL), NAFL with inflammation, and nonalcoholic steatohepatitis (NASH) and identify the presence or absence of liver fibrosis and its degree. Early medication for NAFLD can only be used in patients with pathologically confirmed NASH and liver fibrosis, and it is not recommended to use pioglitazone and vitamin E as the first-line drugs for patients with NASH which has not been proven by biopsy or non-diabetic NASH patients. Foregut bariatric surgery can be considered for obese patients with NAFLD/NASH who meet related indications. It is emphasized that the risk factors for cardiovascular disease should be eliminated for NAFLD patients. Statins can be used for the treatment of dyslipidemia in patients with NAFLD/NASH, but they cannot be used in patients with decompensated liver cirrhosis. Routine screening or hepatocellular carcinoma surveillance is not recommended for NASH patients without liver cirrhosis. Cardiovascular disease should be taken seriously during liver transplantation evaluation. There is still no adequate clinical evidence for the treatment of NAFLD in children and adolescents, and intensive lifestyle intervention is recommended as the first-line therapy for such patients.
