Objective To explore the risk factors for retinopathy in patients with metabolic syndrome.Methods A total of 120 patients with metabolic syndrome admitted to Nanyang Central Hospital from July 2021 to July 2023 were selected as the research subjects,and the patients were categorized into the retinopathy group(n=58)and the non-retinopathy group(n=62)according to the results of fundus examination.The clinical data of patients with metabolic syndrome in both groups were collected and compared.10 mL of blood was collected from the elbow vein of patients in both groups,and the hemoglobin level was measured using a fully automatic blood cell analyzer.The levels of total cholesterol(TC),triacylglycerol(TG),high density lipoprotein-cholesterol(HDL-C),and low density lipoprotein-cholesterol(LDL-C)in the two groups were measured using an automatic biochemical analyzer.The glycosylated hemoglobin(HbA1c)level was determined by high-performance liquid chromatography.The estimated glomerular filtration rate(eGFR)was calculated using the chronic kidney disease epidemiology collaboration equation.Multivariate logistic regression analysis was used to determine the risk factors for retinopathy in patients with metabolic syndrome.Results There were no statistically significant differences in smoking history,drinking history,usage rates of hypoglycemic drugs,lipid-lowering drugs and antihypertensive drugs,systolic blood pressure,cataract,TC,TG,HDL-C,LDL-C,and eGFR between the two groups(P＞0.05).The age,disease duration,insulin usage rate,diastolic blood pressure,HbA1c level,and anemia incidence of patients in the retinopathy group were significantly higher than those in the non-retinopathy group(P＜0.05).Multivariate logistic regression analysis showed that older age,longer disease duration,insulin injection,higher diastolic blood pressure,higher HbA1c level,and lower hemoglobin level were independent risk factors for retinopathy in patients with metabolic syndrome(P＜0.05).Conclusion Old age,long disease duration,insulin injection,high systolic blood pressure,high HbA1c level,and low hemoglobin level are independent risk factors for retinopathy in patients with metabolic syndrome.

Objective To investigate the risk factors and risk prediction model of retinal detachment in patients with myopia.Methods The clinical data of myopic patients treated in our hospital from January 2021 to December 2023 were retrospectively analyzed.A total of 128 patients(128 eyes)with myopic retinal detachment who met the requirements were selected as the retinal detachment group,and 128 myopic patients(128 eyes)without retinal detachment were selected as the control group.The clinical data of patients in the two groups were collected and compared,including age,gender,di-opter,education level,affected side,whether to bear load or not,whether to vibrate or not,whether to have cataract or not,whether to have asthenopia or not,blood pressure,history of diabetes,history of ocular trauma,history of ophthal-mic surgery,and retinal thickness.Risk factors related to retinal detachment in myopia were determined through the multi-variate logistic regression analysis,and based on these factors,the risk prediction model was established.The receiver op-erating characteristic(ROC)curve was used to evaluate the predictive value of the model.Results The age,diopter,systolic blood pressure,cataract incidence,asthenopia incidence,ocular trauma and ophthalmic surgery rates of myopic patients in the retinal detachment group were significantly higher than those in the control group(all P＜0.05).The retinal thickness and choroidal thickness of myopic patients in the retinal detachment group were significantly smaller than those in the control group(both P＜0.05).The risk factors for retinal detachment in myopic patients were older age,higher diopter(absolute value),accompanied by ocular diseases or discomfort such as cataract,asthenopia and ocular trauma,thinner choroid,and thinner retina(all OR＞1,P＜0.05).The areas under the ROC curve(0.95CI)for predication of retinal de-tachment based on age,ocular disease or discomfort,diopter,choroidal thickness,and retinal thickness alone and their combination were 0.668(0.382-0.936),0.645,0.676(0.407-0.942),0.731(0.503-0.933),0.745(0.499-0.983),and 0.844(0.692-0.983),respectively.The area under the curve(0.844),sensitivity,specificity,and accuracy of the prediction model based on the combination of the five indicators were higher,indicating that this model had a better predic-tion effect.Conclusion The risk factors for retinal detachment in myopic patients are older age,higher diopter(abso-lute value),accompanied by ocular diseases or discomfort such as cataract,asthenopia and ocular trauma,thinner cho-roid,and thinner retina.The risk prediction model constructed based on these factors has a high evaluation effect.

Objective: To investigate the expression of lncRNA TUG1 (long non-coding RNA taurine up-regulated gene 1) in gastric cancer and its effect on the proliferation and apoptosis of gastric cancer cells. Methods: Surgically resected gastric cancer tissues and corresponding distal normal tissues (>5 cm away from the margin of tumor) of 40 gastric cancer patients from March 2016 to December 2017 at Ganzhou People's Hospital of Jiangxi Province were collected, and qPCR was used to examine the expression of lncRNA TUG1.AGS gastric cancer cells were transfected with lncRNATUG1 over-expression plasmids and siRNAs, and the effects of lncRNA TUG1 on cell proliferation and apoptosis were assessed by CCK-8, qPCR and Flow cytometry. Results: lncRNATUG1 expression was significantly increased in gastric cancer tissues as compared to normal tissues; and it was not correlated with gender, age, tumor size, infiltration depth of tumor, lymph node-metastasis, tumor differentiation and TNM staging. TUG1 over-expression significantly suppressed the expressions of CDKN1A, BAX and Caspase-3 in AGS gastric cancer cells, and decreased G1 phase proportion and apoptosis rate, but increased S phase proportion and cell viability; in contrast, TUG1 siRNA transfection significantly promoted the expressions of CDKN1A, BAX and Caspase-3, and increased G1 phase proportion and apoptosis rate, but decreased S phase proportion and cell viability. Conclusion: Up-regulated lncRNATUG1 promotes proliferation and inhibits apoptosis of gastric cancer cells.

Objective To investigate the community structure of intestinal bacteria from patients with cirrhosis and its influencing factors. Methods From 2016 to 2017, 24 patients with liver cirrhosis ( the LC group) and 23 healthy family members of patients ( the HC group) were enrolled at the First Hospital of Lanzhou University. A comparative analysis of the community structure of intestinal bacteria was performed using 16S rRNA gene sequencing in LC and HC groups. Combined with LEfSe analysis and NMDS analysis, the differential markers were screened and the factors affecting the intestinal community structure of subjects were studied. Results The dominant six phylum of bacteria in intestines in LC and HC groups included Firmicutes, Bacteroides, Proteobacteria, Actinobacteria, Fusobacteria and Tenericumes. However, in the LC sample, Firmicutes was significantly reduced, while Bacteroides was significantly increased. The diversity of intestinal bacteria was significantly reduced, and the Firmicutes/Bacteroides ratio was significantly decreased, suggesting a variation of the community structure in intestinal bacteria of cirrhosis patients. The LEfSe result indicated that the abundance of Enterococcus, Lactobacillales, Bacilli, and Bacteroidetes showed a significant difference in the LC sample, which may be used as potential marked bacterial groups for cirrhosis. The NMDS analysis revealed a positive relationship between the concentration of Cd and Pb and the abundance of intestinal bacteria in the LC sample. Conclusion The community structure of intestinal bacteria from patients with cirrhosis has changed. Enterococcus, Lactobacillales, Bacilli, and Bacteroidetes are potential marked bacterial groups. The concentration of Cd and Pb in the intestinal tract of cirrhosis patients may interact with the abundance and structure of bacteria, and further affect the occurrence and development of cirrhosis.

Objective To evaluate the impact of the professional knowledge and skills of hospital attendants on the quality of hospital care and its training effect. Methods200 accompanists from a Class ⅢGrade A hospital in Xi'an from January 2017 to December 2018 were selected as the subjects by convenient sampling. 100 accompanists from January to December 2018 were used as observation groups to develop their professional knowledge and skills training; 100 accompanists who did not carry out professional knowledge and skills training during from January to December 2017 were the control group. The professional knowledge and skills, quality of care were compared between the two groups before and after training. ResultsThe scores of basic care, daily life care, psychological care, functional rehabilitation, cleansing care, and communication in the observation group were higher than those in the control group, and the differences between the two groups were statistically significant (P＜ 0.05). After training, the patients' health education awareness rate, complication rate, safety incident rate, and satisfaction were better than before training, and the differences were statistically significant (P＜0.05). ConclusionsDue to the limitation of professional knowledge and skill level, the comprehensive quality of hospital accompanists needs to be improved. Strengthening the training of accompanists can not only improve the comprehensive quality of the accompanists themselves, but also improve the quality of hospital care, which is beneficial to the health and rapidity of the medical care industry.

The final health education program included 2 primary indicators, 11 secondary indicators and 55 tertiary indicators. Conclusions The experts' opinions on the prenatal education program for primiparities and their spouses are consistent. The program is highly scientific and reliable, which provides reference for prenatal health education for primiparities and their spouses based on flipped classroom.

Objective To study the value of score for neonatal acute physiology Ⅱ(SNAP]Ⅱ) and its extension version Ⅱ (SNAPPE-Ⅱ) in predicting neonatal necrotizing enterocolitis (NEC) outcome.Methods We explored 73 NEC patients by statistics who were treated in our hospital from January 2002 to January 2012.The patients were divided into two groups:surgery group and non-surgery group,then they were divided into subgroups:alive group and death group.The general information including birth weight,age,clinical manifestations,treatment of patients were collected.Every patient was checked and scored by the methods SNAP-Ⅱ] and SNAPPE-Ⅱ in time.Results The scores (27.0 ± 2.3,26.5 ± 1.8) of surgery group including SNAP-Ⅱ and SNAPPE-Ⅱ were higher than those (14.0 ± 2.1,15.0 ± 2.5) in the non-surgery group(P ＜ 0.01).The scores(31.0 ± 3.2,31.0 ± 3.4) of the death group including SNAP-Ⅱ and SNAPPE-Ⅱ were higher than those(11.0 ± 2.5,10.0 ± 3.6) in the alive group(P ＜ 0.01).According to the area under the curve(AUC) analyzed by the receiver operating characteristic(ROC) curve for measuring the scores of surgery predicting,AUC was 0.726 for SNAP-Ⅱ and 0.732 for SNAPPE-Ⅱ.The value of predicting surgery risk was 20 and 24 respectively.According to the AUC analyzed by the ROC curve for measuring the scores for surgery predicting,AUC was 0.752 for SNAP-Ⅱ and 0.825 for SNAPPE-Ⅱ.The value of predicting mortality risk was 31 and 33 respectively.All P values were less than 0.01 and there were significant differences.Conclusion The two kinds of score for neonatal acute physiology have an important significance in predicting surgery and mortality risk of NEC.

Objective To study the relationship between umbilical cord leptin levels and fetal growth as well as neonatal birth weight. Methods One hundred and forty - two neonates selected from February 2009 to June 2013 in Shangqiu First People's Hospital according to the different gestational age and birth weight were divided into 3 groups. Group A included 44 cases(small for gestational age,birth weight below the average weight of the 10th percentile at the same gestational age),23 boy cases,21 girl cases;group B included 56 cases(appropriate for gestational age,birth weight at the average weight of the 10th to 90th percentile at the same gestational age),30 boy cases,26 girl cases;group C included 42 cases(large for gestational age,birth weight above the average weight of the 90th percentile at the same gestational age),22 boy cases,20 girl cases. Neonatal body mass index,birth weight,placenta weight and umbilical lep-tin levels of three groups were compared. Results Neonatal birth weight,neonatal body length,body mass index and the placenta weight leptin levels in group A were significantly lower than those of group B,having statistically significant difference(all P ﹤ 0. 001);Neonatal birth weight,neonatal body length,body mass index and the placenta weight leptin levels in group C were significantly higher than those in group B,with statistically significant difference( all P ﹤0. 001). Neonatal birth weight in the boy group was obviously higher than that of the girl group,and the difference was statistically significant(P ﹤ 0. 001). Neonatal leptin levels in the boy group were significantly lower than that of the girl group,and the difference was statistically significant(P ﹤ 0. 001). There were positive correlations between the umbili-cal cord leptin levels and the neonatal birth weight,neonatal length,neonatal weight index and the placenta weight(r =0. 382,0. 276,0. 358,0. 412,all P ﹤ 0. 01). Conclusions The umbilical cord leptin levels are closely associated with neonatal birth weight and intrauterine growth retardation,and it can be used as one of the important indicators for reflec-ting neonatal birth weight and fetal growth.

ObjectiveTo explore the best time for replacing the long-term indwelling catheter in patients with silicone catheter.MethodsDomestic literature were retrieved and analyzed using Cochrane systematic review,and the meta-analysis of randomized controlled trials was conducted in accordance with inclusion criteria and exclusion criteria so as to look into the most suitable time for replacing the indwelling catheter for patients with silicone catheter at clinical trials.The replacement frequency for the catheters of different size together with the relevant infections in urinary tract infection and relative risk(RR)were used as values for effectiveness of interventions.ResultsA total of 11 literature were retrieved. Meta-analysis results suggested that the RR values of urinary tract infections when the catheters were replaced once every two weeks vs. every four weeks,and once every three weeks vs. every four weeks were 0.51[95% CI(0.40,0.66),P <0.001],0.79[95% CI(0.58,1.08),P = 0.14],respectively.The urinary infection rate of replacing a silicone cathether every 2 weeks was higher than that of every 4 weeks,but there was no difference between that of every 3 weeks and 4 weeks.Conclusion According to the nature of silicone catheter material as well as the clinical indexes, it is most reliable to replace a silicone catheter every four weeks to reach a best clinical outcome.

Objective To establish human embryonic stem cells (hESCs) feeder-independent and cell factor-free culture system. Methods Effect of high and low clone densities of hESCs culture was compared and impact of the clone densities to hESCs culture media was analyzed. Results HESCs could maintain their undifferentiated states at high clone density (34 clones/cm2) without cell factors. At the same time,the bone morphology protein (BMP)-like induction of N2 and B27 supplements (NB) medium could be modulated by the clone density,and high level of BMP-like induction was accompanied by high clone density. Conclusion High clone density of hESCs can change the environments by themselves to maintain the undifferentiated states,which provides a new clue to explore the mechanism of undifferentiated states of hESCs and simplify the culture medium.
