Objective To investigate the association of urinary albumin-to-creatinine ratio (UACR) and the diameter of retinal vessel in population with essential hypertension in Fujian coastal area.Methods Central retinal artery and vein equivalents (CRAE and CRVE) were measured from the avoiding mydriatic digitized photographs and semi-automatic fundus analysis software,as well as albumin and urine creatinine.Results There were significant differences in CRAE levels among the normal control group,normoalbuminuria with essential hypertension group and microalbuminuria with essential hypertension group [(135.68 ± 10.10) μm,(129.79 ± 10.48) μm,(125.29 ± 11.17) μm,all P values ＜0.01].The CRAE levels were significantly negative correlated with UACR (r =-0.29,P ＜ 0.01).Linear regression analysis showed CRAE was associated with UACR in the patients with hypertension(β =-5.0,P ＜ 0.01).Logistic regression analysis showed,systolic blood pressure (β =1.08,P =0.02) was risk factor for CRAE abnormality.The CRAE abnormality was increased in turn in the normal control group,normoalbuminuria with the essential hypertension group and microalbuminuria with essential hypertension group (P ＜ 0.01).Conclusion The reduction of central retinal artery diameter are associated with the hypertensive renal damage.UACR and CRAE could be used to evaluate the microvascular lesions and be used as an indicator to assess the target organs damage in essential hypertension patients.

Quinolones are broad-spectrum antibacterial agents used in human and veterinary medicine, and their extensive use have been associated with a rise of the quinolone resistance. In the present study, the quinolone resistance of avian E.coli and Salmonella isolates was evaluated and compared, in which 344 avian E.coli and 224 Salmonella isolates from 1990s were serogrouped with antisera and thc antimicrobial susceptibility test to 10 quinolones was carried out by using the Kirby-Bauer method recommended by Clinical and Laboratory Standards Institute (CLSI). It was demonstrated that the 344 isolates of avian E.coli distributed in 27 serogroups and 68.90% (237/344) of the isolates belonged to four O-serogroups: i.e. O1, O2, O18, O78, and the 224 isolates of avian Salmonella were all determined to be Salmonella pullorum. The drug-resistance rate of avian E. coli isolates to nalicixic acid from 1993-1999 was more than 60%(64.43%,131/181), whereas those of isolates to 9 antibiotics from 2000-2008 had a drug-resistance rates of more than 60%, namely,nalicixic acid(92.02%), fleroxacin(79.75%), pipemidic acid(79.14%), enrofloxacin(78.53%), enoxacin(76.07%), lomenfloxacin(74.85%), ciprofloxacin(69.33%), norfloxacin(63.80%) and ofloxacin(61.35%). For the 4 O-serogroups of the avian E.coli isolates, the drug-resistance rates of more than 50% to antimicrobials were as follows: O78 isolates to 7 antimicrobials;O18 isolates to 5 antimicrobials, and O1 and O2 isolates just to 3 antimicrobials. The quinolone resistance of Salmonella isolates was much lower than E.coli, in which 101 salmonella isolates from 1993-1999 were all susceptible to quinolones. Nalicixic acid resistance of salmonella isolate firstly appeared in 2000, and the drug-resistance rate of salmonella isolates from 2000-2008 was found to be more than 60% for nalicixic acid(83.74%), but those to other quinolones were comparatively lower. These results indicated that the quinolone resistance of avian E.coli and salmonella were increasing in the past two decads because of the over-use of antibiotics.

Objective:Multidrug-resistant tuberculosis(MDR-TB)has a high mortality and is always one of the major challenges in global TB prevention and control.Analyzing the factors that may impact the adverse outcomes of MDR-TB patients is helpful for improving the systematic management and optimizing the treatment strategies for MDR-TB patients.For follow-up data,the Cox proportional hazards regression model is an important multifactor analysis method.However,the method has significant limitations in its application,such as the fact that it is difficult to deal with the impacts of small sample sizes and other practical issues on the model.Therefore,Bayesian and conventional Cox regression models were both used in this study to analyze the influencing factors of death in MDR-TB patients during the anti-TB therapy,and compare the differences between these 2 methods in their application. Methods:Data were obtained from 388 MDR-TB patients treated at Lanzhou Pulmonary Hospital from November 1,2017 to March 31,2021.Survival analysis was employed to analyze the death of MDR-TB patients during the therapy and its influencing factors.Conventional and Bayesian Cox regression models were established to estimate the hazard ratios(HR)and their 95% confidence interval(95% CI)for the factors affecting the death of MDR-TB patients.The reliability of parameter estimation in these 2 models was assessed by comparing the parameter standard deviation and 95% CI of each variable.The smaller parameter standard deviation and narrower 95% CI range indicated the more reliable parameter estimation. Results:The median survival time(1st quartile,3rd quartile)of the 388 MDR-TB patients included in the study was 10.18(4.26,18.13)months,with the longest survival time of 31.90 months.Among these patients,a total of 12 individuals died of MDR-TB and the mortality was 3.1%.The median survival time(1st quartile,3rd quartile)for the deceased patients was 4.78(2.63,6.93)months.The majority of deceased patients,accounting for 50%,experienced death within the first 5 months of anti-TB therapy,with the last mortality case occurring within the 13th month of therapy.The results of the conventional Cox regression model showed that the risk of death in MDR-TB patients with comorbidities was approximately 6.96 times higher than that of patients without complications(HR=6.96,95% CI 2.00 to 24.24,P=0.002)and patients who received regular follow-up had a decrease in the risk of death by approximately 81% compared to those who did not receive regular follow-up(HR=0.19,95% CI 0.05 to 0.77,P=0.020).In the results of Bayesian Cox regression model,the iterative history plot and Blue/Green/Red(BGR)plot for each parameter showed the good model convergence,and parameter estimation indicated that the risk of death in patients with a positive first sputum culture was lower than that of patients with a negative first sputum culture(HR=0.33,95% CI 0.08 to 0.87).Additionally,compared to patients without complications,those with comorbidities had an approximately 6.80-fold increase in the risk of death(HR=7.80,95% CI 1.90 to 21.91).Patients who received regular follow-up had a 90% reduction in the risk of death compared to those who did not receive regular follow-up(HR=0.10,95% CI 0.01 to 0.30).The comparison between these 2 models showed that the parameter standard deviations and corresponding 95% CI ranges of other variables in the Bayesian Cox model were significantly smaller than those in the conventional model,except for parameter standard deviations of receiving regular follow-up(Bayesian model was 0.77;conventional model was 0.72)and pulmonary cavities(Bayesian model was 0.73;conventional model was 0.73). Conclusion:The first year of anti-TB therapy is a high-risk period for mortality in MDR-TB patients.Complications are the main risk factors of death in MDR-TB patients,while patients who received regular follow-up and had positive first sputum culture presented a lower risk of death.For data with a small sample size and low incidence of outcome,the Bayesian Cox regression model provides more reliable parameter estimation than the conventional Cox model.

Objective To investigate the clinical application on Wechat for health education in discharged patients with PICC catheter.Methods Totals of 120 discharged patients with PICC catheter were selected from January to December in 2013,they were divided into the Wechat group (68 cases) and control group (52 cases) by random numerical table method.Before discharging from hospital,both groups received health education of PICC catheter and self-nursing instruction.The control group was given the telephone visits regularly and outpatient PICC consultation in hospital.Besides,the Wechat group was aggregated in a group,in which the self-nursing education and maintenance knowledge of PICC catheter were provided,and the questions from patients were answered timely as well.The awareness of self-nursing of PICC catheter and rate of patients' satisfaction for health education were compared between the two groups.Results The awareness self-nursing of patients in the Wechat group was 95％,while the control group was 77％.There was significant difference between the two groups (x2 =11.73,P ＜ 0.01).The rate of patients' satisfaction in the Wechat group was 97％,while the control group was 75％.There was significant difference between the two groups(x2 =8.23,P＜0.01).Conclusions Setting up a Wechat group can increase self-nursing education of the discharged patients with PICC catheter as well as the rate of patients' satisfaction.

Objective:To observe the changes of skeletal muscle indexes in elderly patients with type 2 diabetes complicated with sarcopenia treated with sitagliptin and acarbose.Methods:A total of 60 patients over 60 years old with type 2 diabetes complicated with sarcopenia in Dalian Municipal Central Hospital from January 2019 to January 2020 were selected and divided into two groups by random number table method.One group received sitagliptin and metformin,and the other group received acarbose and metformin. The changes of skeletal muscle indexes, glucagon-like peptides-1 (GLP-1), insulin resistance index (HOMA-IR) and inflammatory indexes were compared between the two groups at baseline and 36 weeks after treatment.Results:After treatment, the skeletal muscle index (SMI) of sitagliptin group was increased (5.94 ± 1.52 vs. 5.99 ± 1.52), and the difference was statistically significant ( P<0.05). Muscle strength and SMI decreased in acarbosse group (18.75 ± 4.64 vs. 17.72 ± 4.44, 6.09 ± 1.74 vs. 6.00 ± 1.71), with statistical significance ( P<0.05). GLP-1 increased in sitagliptin group, 0 min: (10.65 ± 1.68) pmol/L vs. (12.41 ± 1.88) pmol/L; 60 min: (22.79 ± 2.85) pmol/L vs. (25.51 ± 2.79) pmol/L; 120 min: (24.26 ± 2.94) pmol/L vs. (29.49 ± 2.91) pmol/L; 180 min: (11.68 ± 1.84) pmol/L vs. (12.88 ± 1.83) pmol/L. There were significant differences ( P<0.05). HOMA-IR and CRP decreased: 4.73 ± 3.04 vs. 3.16 ± 2.41, (2.39 ± 0.50) mg/L vs. (2.33 ± 0.43) mg/L, and the differences were statistically significant ( P<0.05). HOMA-IR in acarbose group decreased after treatment (5.80 ± 3.94 vs. 4.00 ± 1.63), and the difference was statistically significant ( P<0.05). Comparison between the two groups after treatment, the decreased value of muscle strength in sitagliptin group was less than that in acarbose group, and the difference was statistically significant ( P<0.05). GLP-1 and overall GLP-1 area under the curve in sitagliptin group were higher than those in acarbose group (67.64 ± 6.81 vs. 58.98 ± 6.72), with statistical significance ( P<0.05). HOMA-IR and CRP in sitagliptin group were lower than those in acarborose group: 3.16 ± 2.42 vs. 4.00 ± 1.63, (2.33 ± 0.43) mg/L vs. (2.41 ± 0.70) mg/L, with statistical significances ( P<0.05). Conclusions:Sitagliptin therapy improves muscle mass and protects muscle strength in elderly patients with type 2 diabetes mellitus and sarcopenia.

Objective:To design an oral methotrexate auxiliary device and explore the effect of methotrexate in patients with rheumatoid arthritis.Methods:Totally 30 patients with rheumatoid arthritis were selected and observed continuously for 12 months, from January to June in 2021, in the Affiliated Changzhou No. 2 People ′s Hospital of Naijing Medical University. The subjects took the medicine routinely in the first 6 months after entering the group, and the methotrexate oral drug assistant device was given in the latter 6 months to remind them to take the medicine correctly. Medication administration of patients before and after using the auxiliary device was compared, and the evaluation indexes such as disease activity, medication compliance and anxiety were observed. Results:Without the auxiliary device, there were 14 cases (46.67%) of medication error, 13 cases (43.33%) of medication time error, 9 cases (30.00%) of missed administration, while after the use of the auxiliary device, there were 4 cases (13.33%) of medication error, 2 cases (6.67%) of medication time error and 2 cases (6.67%) of missed administration, and the differences were statistically significant ( χ2=8.10, 9.09, 5.14, all P<0.05). Moreover, before using the auxiliary device, the scores of disease activity and medication compliance were 3.92 ± 0.95, 84.97 ± 6.49, respectively, while with the help of the auxiliary device, those scores changed to 3.29 ± 0.83, 92.40 ± 4.17 respectively. All the differences were statistically significant ( t=10.06, -10.37, both P<0.01). 16 cases (53.33%) were anxious after using the assistive device, which was also better than 26 cases (86.67%) before using the device. The difference was statistically significant ( χ2=8.10, P<0.01) . Conclusions:Oral administration aid for methotrexate can help rheumatoid arthritis patients to take methotrexate correctly and safely, reducing disease activity and anxiety, improving drug compliance. It is worthy to clinical promotion.
