Objective To investigate the duration for silicon gastric tube to indwell in stomach of aged patients.Methods One hundred elderly patients needing long-term nutrition support were equally randomized into two groups: control group and observation group.The former had the gastric tubes indwelled in the stomach for 4 weeks and the latter for 3 weeks.The two groups were compared about the used tubes in terms of the color of tube at the length of the first 10cm,the indentation by reflection for 10 seconds at the tube of first 10 cm,the hardness of the tube at the length of the first 10 cm and the springback angle of tube at the first 10cm after reflection.Results The tubes in the observation group were significantly better than those in the control group in terms of color,indentation,hardness and springback angle(all P<0?01).Conclusion The duration of indwelling silicon gastric tubes in stomach can be three weeks for old patients needing long-term nutrition support via indwelling silicon tubes in their stomach.

Objective To explore disinfection efficacy of anerdian using swab and spray disinfection methods.Methods Hands of 30 subjects were randomly divided into the swab group and the spray group.The samples of before and after disinfection in each group were collected separately and observed their disinfection effect.Results The number of bacteria showed no significant difference between the two groups.The passing rate of disinfection reached 100％.The time of disinfection in the spray group was (2.58±0.32)s,significantly less than that in the swab group,(12.26±1.48)s,however,the drying time in the spray group was (42.37±1.79)s,significant longer than that in the swab group,(26.24±1.46)s.A subject hand disinfection used 0.5ml 0.2％ anerdian in the spray group,and 0.75ml 0.2％ anerdian and two cotton buds was used in the swab group.Conclusions There is identical disinfection efficacy between spray and swab methods.Spray disinfection method has short operating time,less use of disinfectant without using cotton buds,it is able to replace swab disinfection and will play an important role to reduce medical waste and health care costs.

Objective To investigate the current status of type 2 diabetic patients who failed to achieve the glycemic control target, and provide theoretic evidences for making corresponding strategies. Methods The 2 diabetic patients who failed to reach the glycemic target were recruited from 181 hospitals in 26 cities and received a standard questionnaire, the conditions of their blood glucose level, lifestyle intervention, blood sugar monitoring, and drug therapy were recorded. Totally 3 861 questionnaires with complete information were collected. And the causes which account for glycemic control status were analyzed. Results Among these patients, the mean HbA1c was 7.9%, the mean fasting plasma glucose was 8.2 mmol/L, and the mean postprandial plasma glucose was 11.5 mmol/L. Only 25.6% of patients take their diet control strictly as prescribed and 44. 5% of patients have little exercise. 35. 8% and 47.8% of patients did not monitor their fasting and postprandial plasma glucose,respectively. Glycemic control in the patients aged ＞ 60 years was similar to the younger patients, but the hypoglycemia incidence in the elder group reached 35.5%, which was higher than those in the other 2 groups (20.8% and 21.4%, both P＜0. 05 ). The proportion of patients with mono-therapy and combination therapy was 46. 1% and 51.7%, while the proportion with combination therapy rose in the patients aged ＞60 years (58.7%;Compared with the other age-groups, all P＜0.05 ). 75 % of patients have adjusted their drug administration regimen since initial treatment. Conclusions Inadequate or inappropriate drug therapy regimen is a major cause responsible for this poor glycemic control status. In addition, the unhealthy life styles, insufficient blood sugar monitoring, and poor compliance were also important causes. Thus, for these patients, it is necessary to further enhance patients' education, to improve life style intervention, as well as to select more effective, safer, and compliant drug therapy regimens. Finally, the glycemic control target for the elder patients should be more flexible.

Objective:To investigate the correlation between serum concentration of vasohibin-1 (VASH-1) and urinary albumin creatinine ratio (UACR) in patients with type 2 diabetes mellitus (T2DM) and diabetic nephropathy.Methods:The clinical data of 196 patients with T2DM from February 2017 to December 2020 were analyzed retrospectively. According to whether diabetic nephropathy (DN) was combined, 33 patients without DN of T2DM were divided into the control group,and 163 patients with DN of T2DM were divided into the case group, and the case group was divided into four groups:normal albuminuria group (groupⅠ, UACR <30 mg/g, 21 cases),microalbuminuria group (groupⅡ, UACR ≥30-≤300 mg/g, 50 cases), clinical albuminuria group (group Ⅲ, UACR>300 mg/g, 43 cases), and clinical albuminuria hypertensive group (groupⅣ, UACR >300 mg/g with hypertension, 49 cases). Serum levels of VASH-1,C-reactive protein(CRP), erythrocyte sedimentation rate (ESR) and transforming growth factor β1 (TGF-β1) with other biochemical indicators were measured. T-test was used for comparison between measurement data groups in accordance with normal distribution, one-way ANOVA was used for comparison between multiple groups, q-test was used for pairwise comparison, and χ2 test was used for comparison between counting data groups. The influencing factors were analyzed by multivariate Logistic regression.Pearson correlation analysis was used to analyze the correlation between vash-1 and UACR. Results:UACR((1 175.9±120.4) mg/g), CRP((9.80±2.01) mg/L), ESR((20.61±2.20) mm/h),TGF-β1((16.75±2.05) μg/L), VASH-1((645.3±183.5) ng/L) in case group were higher than that in the control group((11.5±2.0) mg/g, (4.77±1.34) mg/L, (8.33±1.56) mm/h, (10.63±1.97) μg/L, (416.3±162.1) ng/L), and there were significant differences between the two groups ( t=123.39,13.76,30.54,15.75,6.66; all P<0.001). Multivariate logistic regression analysis showed that VASH-1 ( OR=1.881,95% CI 1.146-3.089), UACR( OR=1.511,95% CI 1.064-2.146), TGF-β1( OR=1.846,95% CI 1.135-3.001)were all risk factors for DN of T2DM ( P values were 0.009, 0.022 and 0.012). Serum VASH-1 ((693.5±201.4), (709.8±214.7) ng/L] in group Ⅲ and group Ⅳ were higher than those in group Ⅰ and group Ⅱ ((585.3±162.1), (632.9±165.5) ng/L). There was significant difference between the two groups ( F=129.46, P<0.001). The CRP ((7.08±1.36), (8.99±3.72), (10.58±3.48), (11.64±3.50) mg/L), ESR ((17.36±1.76), (19.05±4.12), (21.45±5.74), (22.69±9.13) mm/h) and TGF- β1 ((14.75±1.97), (16.50±1.90), (17.06±1.23), (18.39±1.46) μg/L) of groupⅠ, groupⅡ, groupⅢ and groupⅣ increased gradually, and there were significant differences between the four groups ( F values were 73.48, 156.61, 25.83; all P<0.001). Pearson correlation analysis showed that there was a significant positive correlation between VASH-1 and UACR ( r=0.532, P=0.008). Conclusion:The concentration of VASH-1 in serum of patients with T2DM complicated with DN increased with the increase of UACR. VASH-1 may become a new marker for predicting early DN of T2DM.

Objective:To conduct a systematic review of clinical manifestations, treatment, and associated genotyping of Sorsby fundus dystrophy (SFD).Methods:An evidence-based medicine study. Sorsby fundus dystrophy, anti-vascular endothelial growth factor therapy, choroidal neovascularization, macular neovascularization, and TIMP3 gene were hereby used as search terms. Relevant literature was searched in CNKI, Wanfang, PubMed of the National Library of Medicine, and Embase of the Netherlands. The time span for literature searching ranged from the establishment of the database to April 2022, and two reviewers independently screened the literature and extracted relevant data, with duplicates, incomplete or irrelevant articles, and review articles excluded. SPSS26.0 software was used for analysis. The 95% confidence interval ( CI) was used as an estimate of the effect size. The clinical manifestations, treatment and related pathogenic genes of SFD were counted and recorded. Results:According to the search strategy, 157 pieces of literature were initially retrieved, and 49 eyes of 35 patients from 16 articles were finally included for analysis, among which, 17 patients were male, 13 patients were female, and 5 patients were unknown gender; 16 involved left eyes, 19 involved right eyes, and 14 involved unidentified eyes. The age of the disease onset was 42.33±2.19 years (28-59) years old. There were 19 cases with a positive family history, and the total positive rate was 54.3% (19/35, 95% CI 36%-72%). There were 31 cases of gene mutation, all of which were TIMP3. In the included literature, there were 2 and 2 cases with no mutation and unreported loci, respectively, with a total positive rate of 93.9% (31/33, 95% CI 85%-100%). Among the 31 cases with gene mutation, 22, 4, 1, and 4 cases were in the UK, Germany, Switzerland, and Chinese, respectively, and the detection rates were all 100% (22/22, 4/4, 1/1, 4/4). The clinical manifestations of SFD were mainly yellow-white deposits in the fundus and choroidal neovascularization (CNV) in the macula, thereby leading to a decrease in central vision, followed by the expansion of the deposits to the periphery, the further development of CNV, and a severe decline in vision caused by peripheral retinal and choroidal atrophy. The treatment methods for SFD include photodymatic therapy, anti-VEGF drugs, glucocorticoids, vitamin A, etc., among which, anti-VEGF drugs were considered the first-line treatment, and the combined treatment was provided with a better prognosis than a single treatment. Conclusions:Variations in the TIMP3 gene cause SFD, the fundus characteristic manifestations of which, are yellowish-white deposits and CNV, which develop from the center to the periphery, thus resulting in progressive decline of visual acuity. Current studies have shown that combined therapy presents a better prognosis than monotherapy.

Objective The aim of this study was to investigate the prognostic value of body composition indicators in evaluating the development risk of gestational diabetes mellitus(GDM).Methods A total of 1431 pregnant women who were registered and underwent prenatal examinations in the Clinical Nutrition Department of Guizhou Hospital of Beijing Jishuitan Hospital were selected in this study from January 2018 to September 2021.Among them,263 participants were diagnosed with GDM(GDM group),and 1168 healthy individuals underwent physical examinations were enrolled as Con group.Results The GDM detection rate was 18.38%(263/1431).Logistic regression analysis showed that age and percent body fat were risk factors for the development of GDM.The area under the ROC curve of percent body fat for GDM prediction was 0.732,with sensitivity,specificity of 67.7%,68.3%.Conclusions High percentage of body fat during pregnancy is a risk factor for the development of GDM in late pregnancy,and the risk of developing diabetes during pregnancy can be predicted by the percentage of body fat index.
