Abstract
BACKGROUND Early screening and accurate staging of diabetic retinopathy (DR) can reduce blindness risk in type 2 diabetes patients. DR's complex pathogenesis involves many factors, making ophthalmologist screening alone insufficient for prevention and treatment. Often, endocrinologists are the first to see diabetic patients and thus should screen for retinopathy for early intervention. AIM To explore the efficacy of non-mydriatic fundus photography (NMFP)-enhanced telemedicine in assessing DR and its various stages. METHODS This retrospective study incorporated findings from an analysis of 93 diabetic patients, examining both NMFP-assisted telemedicine and fundus fluorescein angiography (FFA). It focused on assessing the concordance in DR detection between these two methodologies. Additionally, receiver operating characteristic (ROC) curves were generated to determine the optimal sensitivity and specificity of NMFP-assisted telemedicine, using FFA outcomes as the standard benchmark. RESULTS In the context of DR diagnosis and staging, the kappa coefficients for NMFP-assisted telemedicine and FFA were recorded at 0.775 and 0.689 respectively, indicating substantial intermethod agreement. Moreover, the NMFP-assisted telemedicine's predictive accuracy for positive FFA outcomes, as denoted by the area under the ROC curve, was remarkably high at 0.955, within a confidence interval of 0.914 to 0.995 and a statistically significant P-value of less than 0.001. This predictive model exhibited a specificity of 100%, a sensitivity of 90.9%, and a Youden index of 0.909. CONCLUSION NMFP-assisted telemedicine represents a pragmatic, objective, and precise modality for fundus examination, particularly applicable in the context of endocrinology inpatient care and primary healthcare settings for diabetic patients. Its implementation in these scenarios is of paramount significance, enhancing the clinical accuracy in the diagnosis and therapeutic management of DR. This methodology not only streamlines patient evaluation but also contributes substantially to the optimization of clinical outcomes in DR management.

Abstract
Objective: To understand the basic characteristics of previously reported patients with hepatitis C and analyze the related factors affecting their antiviral treatment. Methods: A convenient sampling method was adopted. Patients who had been previously diagnosed with hepatitis C in the Wenshan Prefecture of Yunnan Province and Xuzhou City of Jiangsu Province were contacted by telephone for an interview study. The Andersen health service utilization behavior model and related literature were used to design the research framework for antiviral treatment in previously reported hepatitis C patients. A step-by-step multivariate regression analysis was used in previously reported hepatitis C patients treated with antiviral therapy. Results: A total of 483 hepatitis C patients, aged 51.73 ± 12.06 years, were investigated. The proportion of male, agricultural occupants who were registered permanent residents, farmers and migrant workers was 65.24%, 67.49%, and 58.18%, respectively. Han ethnicity (70.81%), married (77.02%), and junior high school and below educational level (82.61%) were the main ones. Multivariate logistic regression analysis results showed that married patients with hepatitis C (OR = 3.19, 95% CI: 1.93-5.25, compared with unmarried, divorced, and widowed patients) with high school education or above (OR = 2.54, 95% CI: 1.54-4.20, compared with patients with junior high school education or below) were more likely to receive antiviral treatment in the predisposition module. Patients with severe self-perceived hepatitis C in the need factor module (compared with patients with mild self-perceived disease, OR = 3.36, 95% CI: 2.09-5.40) were more likely to receive treatment. In the competency module, the family's per capita monthly income was more than 1,000 yuan (compared with patients with per capita monthly income below 1,000 yuan, OR = 1.59, 95% CI: 1.02-2.47), and the patients had a high level of awareness of hepatitis C knowledge (compared with patients with a low level of knowledge, OR = 1.54, 95% CI: 1.01-2.35), and the family members who knew the patient's infection status (compared with patients with an unknown infection status, OR = 4.59, 95% CI: 2.24-9.39) were more likely to receive antiviral treatment. Conclusion: Different income, educational, and marital statuses are related to antiviral treatment behavior in hepatitis C patients. Family support of hepatitis C patients receiving hepatitis C-related knowledge and their families knowing the infection status is more important in promoting the antiviral treatment of patients, suggesting that in the future, we should further strengthen the hepatitis C knowledge of hepatitis C patients, especially the family support of hepatitis C patients' families in treatment.

Abstract
Objective: To verify the efficacy and safety of daily oral minodronate in postmenopausal women with established osteoporosis. Methods: In this randomized, double-blinded, placebo-controlled trial, 262 postmenopausal women were enrolled. Patients were randomized to receive daily oral minodronate 1 mg with supplements of 500 mg calcium and 200 U vitamin D3 (n=130) or placebo (n=132) with daily supplements of 500 mg calcium and 200 U vitamin D3, for 48 weeks. The primary endpoint was the average bone mineral density (BMD) change in the lumbar vertebrae 48 weeks post-treatment. Secondary outcome measures was the incidence of vertebral fractures. Safety assessments included the rate of adverse events. Results: At the end of 48 weeks treatment, the average BMD change rate from baseline were: full analysis set results: (3.52±4.82)% in the minodronate group and (2.00±5.74)% in the placebo group; per-protocol set results: (3.99±5.05)% in the minodronate group and (2.07±6.20)% in the placebo group; the differences were all significant (all P<0.05). Vertebral fracture occured in 3 patients (2.3%, 3/132) in the placebo group, and 1 case (0.8%, 1/130) in the minodronate group (P>0.05). The incidence of adverse events was 71.5% (93/130) in the minodronate group and 78.0% (103/132) in the placebo group (P>0.05). Conclusion: Minodronate is effective and safe in the treatment of postmenopausal osteoporosis without severe side effects.

Abstract
BACKGROUND Atherosclerosis is a major cause of mortality worldwide and is driven by multiple risk factors, including diabetes, which results in an increased atherosclerotic burden, but the precise mechanisms for the occurrence and development of diabetic atherosclerosis have not been fully elucidated.
AIM To summarize the potential role of retinol binding protein 4 (RBP4) in the pathogenesis of diabetic atherosclerosis, particularly in relation to the RBP4-Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling pathway.
METHODS Male Wistar rats were randomly divided into three groups, including a control group (NC group), diabetic rat group (DM group), and diabetic atherosclerotic rat group (DA group). The contents of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-c), triglycerides (TG), low-density lipoprotein cholesterol (LDL-c), fasting insulin (FINS), fasting plasma glucose, and hemoglobin A1c (HbA1c) were measured. Moreover, the adipose and serum levels of RBP4, along with the expression levels of JAK2, phosphorylated JAK2 (p-JAK2), STAT3, phosphorylated STAT3 (p-STAT3), B-cell lymphoma-2 (Bcl-2), and Cyclin D1 in aortic tissues were also measured. Besides, homeostasis model assessment of insulin resistance (HOMA-IR) and atherogenic indexes (AI) were calculated.
RESULTS Compared with the NC and DM groups, the levels LDL-c, TG, TC, FINS, HOMA-IR, RBP4, and AI were upregulated, whereas that of HDL-c was downregulated in the DA group (P < 0.05); the mRNA levels of JAK2, STAT3, Cyclin D1, and Bcl-2 in the DA group were significantly increased compared with the NC group and the DM group; P-JAK2, p-JAK2/JAK2 ratio, p-STAT3, p-STAT3/STAT3 ratio, Cyclin D1, and Bcl-2 at protein levels were significantly upregulated in the DA group compared with the NC group and DM group. In addition, as shown by Pearson analysis, serum RBP4 had a positive correlation with TG, TC, LDL-c, FINS, HbA1C, p-JAK2, p-STAT3, Bcl-2, Cyclin D1, AI, and HOMA-IR but a negative correlation with HDL-c. In addition, multivariable logistic regression analysis showed that serum RBP4, p-JAK2, p-STAT3, and LDL-c were predictors of the presence of diabetic atherosclerosis.
CONCLUSION RBP4 could be involved in the initiation or progression of diabetic atherosclerosis by regulating the JAK2/STAT3 signaling pathway.

Abstract
BACKGROUND p.Tyr329fs is a cytochrome P450c17 mutation among Chinese individuals. However, data on 17-α-hydroxylase deficiency caused by cytochrome P450c17 p.Tyr329fs homozygous mutation are lacking. This paper is a case report of three patients homozygous for p.Tyr329fs who were diagnosed with 17-α-hydroxylase deficiency between 2005 and 2019.
CASE SUMMARY Case 1 presented with hypertension, hypokalemia, sexual infantilism and delayed bone age. The patient had a 46, XY karyotype, was homozygous for p.Tyr329fs and was recently treated with dexamethasone 0.375 mg qn. Case 2 presented with hypokalemia, sexual infantilism, osteoporosis and delayed bone age. The patient had a 46, XY karyotype, was homozygous for p.Tyr329fs and was treated with dexamethasone 0.75 mg qn at the last follow-up. Serum potassium and blood pressure could be maintained within normal range for cases 1 and 2. Case 3 presented with amenorrhea, sexual infantilism, osteopenia and delayed bone age. The patient had a 46, XX karyotype, was homozygous for p.Tyr329fs and was treated with dexamethasone 0.75 mg qn and progynova 1 mg qd. Outpatient follow-up revealed an adrenocorticotropic hormone (8 AM) of < 5.00 pg/mL.
CONCLUSION The homozygous p.Tyr329fs mutation usually manifests as a combined deficiency, and definitive diagnosis depends primarily on genetic testing.

Abstract
Objective: To understand the hepatitis C diagnosis type, progression and treatment in medical institutions. Methods: Monitoring posts were set up in the secondary and tertiary-level hospitals in some parts of the country. Reported infectious diseases cases of hepatitis C in sentinel hospitals during the three consecutive years from 2017 to 2019 were investigated to understand their general demographic characteristics, diagnosis, liver fibrosis degree, and treatment. The diagnosis, treatment and related factors were analyzed by chi square test and trend. Results: A total of 16 241 cases of hepatitis C were investigated in three years. Among them, 7 538 cases were clinically diagnosed (46.41%) and 8703 cases (53.59%) were confirmed as hepatitis C. Among the confirmed cases, 60 cases (0.69%) were acute and 8643 cases (99.31%) were chronic. In the past three years, the proportion of cases diagnosed by liver diseases related departments decreased from 62.23% to 40.01%, while the proportion of medical and surgical cases of non-liver diseases increased from less than 30% to nearly 60%. The proportion of confirmed cases in secondary hospitals (26.27%) was significantly lower than that in tertiary hospitals (62.48%), and the difference was statistically significant (χ (2) = 1594.833, P < 0.001). There were also differences in the proportion of confirmed cases in different regions (P < 0.001). The cases with FIB-4 > 3.25 accounted for 35.78%, and the proportion was increased significantly with age (χ (2) trend = 1159.624, P < 0.001). The average proportion of antiviral treatment was less than 10%, and the proportion of antiviral treatment in secondary hospitals was very low (2.13%); however, the proportion of liver-protective monotherapy treatment was decreased from 30.40% in 2017 to 11.14% in 2019, and the difference was statistically significant (P < 0.001). Conclusion: The large-scale screening of hepatitis C by medical institutions is increasing year by year, but only about half of the cases can be diagnosed, and the diagnostic capacity of secondary hospitals is particularly unsatisfactory. Most of the confirmed cases are chronic hepatitis C, and more than one third of them have abnormal liver fibrosis indicators, and the proportion increases with age. The proportion of antiviral treatment for hepatitis C is lower in secondary than tertiary-level hospitals. Therefore, there is an urgent need to raise the attention of both parties (doctors and patients) to enhance diagnostic capabilities and expand the coverage of antiviral treatment for hepatitis C.

Abstract
The effect of intensive insulin therapy on hyperglucagonemia in newly diagnosed type 2 diabetes (T2DM), and its associations with β-cell function, has not been elucidated. This study assessed the effect of 12 weeks of intensive insulin therapy on hyperglucagonemia in newly diagnosed T2DM and its associations with β-cell function, with reference to the effects of 12 weeks of oral hypoglycemic agents (OHAs).One hundred eight patients with newly diagnosed T2DM were enrolled from January 2015 to December 2015. The patients were randomly divided to receive, for 12 weeks, either intensive insulin therapy or OHAs. Meal tolerance tests were conducted at baseline before treatment (0 week), at 12 weeks (end of treatment), and 12 months after the initiation of treatment. The levels of glucagon, proinsulin, C-peptide (CP), and blood glucose were measured at timepoints 0, 30, and 120 minutes during the meal tolerance test.Intensive insulin treatment was associated with a decrease in glucagon levels (at 0, 30, and 120 minutes) and proinsulin/CP, and an increase in the insulin-secretion index ΔCP30/ΔG30 and ΔCP120/ΔG120, at 12 weeks and 12 months during the follow-up, compared with the corresponding effects of OHAs. Intensive insulin therapy could reduce but failed to normalize glucagon levels at 12 weeks. There were no correlations between the change of percentages in total area under the curve of glucagon and other glycemic parameters (proinsulin/CP; ΔCP30/ΔG30; or ΔCP120/ΔG120). Patients who received intensive insulin therapy were more likely to achieve their target glycemic goal and remission, compared with those who received OHAs.Short-term intensive insulin therapy facilitates the improvement of both β-cell and α-cell function in newly diagnosed T2DM mellitus. Decline of β-cell secretion and concomitant α-cell dysfunction may both be involved in the pathogenesis of T2DM.

Abstract
Objective: To analyze the deaths with antiretroviral treatment among adult HIV/AIDS patients in Liangshan Yi Autonomous Prefecture from 2005 to 2015, in order to understand the epidemiological characteristics and to further reduce the mortality rate in Liangshan Prefecture. Methods: The relevant information was collected through the Management Database of Antiretroviral Treatment from the National AIDS Comprehensive Prevention Information System. Results: From 2005 to 2015, a total of 14 219 adult HIV/AIDS patients received antiretroviral treatment and 1 425 death cases were reported during the treatment. The cause of death was mainly AIDS-related diseases (58.9%), and the cumulative mortality rate was 10.02%. Gender, age, the way of infection, duration of antiretroviral therapy, clinical stage when received antiretroviral therapy, and CD(4)(+) T lymphocyte levels were factors for the mortality rate (P<0.001). The mortality increased with older age, higher initiation clinical stage and lower level of CD(4)(+) T lymphocyte. Among the death cases, 82.6% were male, 1 182 (82.9%) were married or cohabited, most aged between 30-39 years old (48.6%). At the initial point of receiving antiretroviral therapy, 49.7% of the cases with CD(4)(+)T lymphocytes levels< 200/μl, 61.2% of the deaths cases were>1 000 copies/ml during the last viral load test, and 16.2% of deaths were ≥500/μl in the last CD(4)(+)T lymphocyte test; 44.5% of deaths were received antiretroviral treatment within one year. Conclusion: Early and timely antiretroviral therapy should be carried out. It is necessary to strengthen the propaganda of antiretroviral therapy and to improve the management quality of follow-up information of antiretroviral therapy case files, and to improve the medication compliance of patients.

Abstract
BACKGROUND Epidemiological studies have identified an association between thyroid dysfunction (TD) and various kidney diseases. In this study, the prevalence of TD in type 2 diabetic mellitus (T2DM) patients with diabetic kidney disease (DKD) was evaluated to analyse the potential association between TD and DKD in T2DM patients. METHODOLOGY A total of 2108 T2DM patients from Anhui Provincial Hospital were recruited in this study. Demographic and clinical characteristics were collected from 834 T2DM patients with DKD and 1274 T2DM patients without DKD (non-DKD). All patients were stratified into a number of groups based on UACR (urine albumin-to-creatinine ratio) or eGFR (estimated glomerular filtration rate): (a) A1: normoalbuminuria (<30), A2: microalbuminuria (30-300) and A3: macroalbuminuria (>300); (b) F1: normal filtration (60-139), F2: hyper filtration (≥140) and F3: low filtration (<60). RESULTS Significant differences were observed between the non-DKD and DKD groups (P < .05) in age, sex ratio, duration, systolic blood pressure, total cholesterol, low density lipoprotein cholesterol, serum creatinine, blood urea nitrogen, free triiodothyronine (FT3), free thyroxine (FT4) and sensitive thyrotropin hormone (sTSH). The macroalbuminuira and low filtration groups had the lowest levels of FT3 and FT4 and the highest level of sTSH, compared with all other groups (P < .0167). The prevalence of subclinical hypothyroidism in the DKD group was significantly higher than that in the non-DKD group (χ2 = 13.92, P < .01). Logistic regression analysis showed that hypothyroidism was associated with increased UACR or reduced eGFR in T2DM patients. Compared with controls, T2DM patients with hypothyroidism exhibited a higher UACR and urinary excretion of transferrin, as well as a lower excretion of urinary Tamm-Horsfall protein (THP) (P < .0167). CONCLUSION Subclinical hypothyroidism is more prevalent in T2DM patients with DKD than in T2DM patients without DKD. Hypothyroidism is associated with albuminuria and decreased eGFR in T2DM patients.

Abstract
Objective: To understand the prevalence of hepatitis C virus (HCV) infection in 5 populations in China during 2016-2017 and provide evidence for the estimation of prevalence trend of hepatitis C and evaluation on the prevention and control effect. Methods: A total of 87 national sentinel surveillance sites for hepatitis C were set up in 31 provinces (autonomous regions and municipalities) of China to obtain the information about HCV infection prevalence in 5 populations, including volunteer blood donors, people receiving physical examination, patients receiving invasive diagnosis and treatment, patients receiving hemodialysis, and clients visiting family planning outpatient clinics. From April to June, 2016 and 2017, cross-sectional surveys were repeatedly conducted in the 5 populations and blood samples were collected from them for HCV antibody detection. Results: In 2016, 86 sentinel sites completed the surveillance (one sentinel site was not investigated), and 115 841 persons were surveyed. The overall HCV positive rate was 0.38% (442/115 841, 95%CI: 0.23%-0.53%). In 2017, all the 87 sentinel sites completed the surveillance, and 120 486 persons were surveyed. The overall HCV positive rate was 0.37% (449/120 486, 95%CI: 0.23%-0.52%). In 2016 and 2017, the anti-HCV positive rates were 4.46% (223/5 005, 95%CI: 2.18%-6.73%) and 4.39% (216/4 919, 95%CI: 2.29%-6.50%) respectively in hemodialysis patients, 0.85% (44/5 200, 95%CI: 0.27%-1.42%) and 0.70% (36/5 150, 95%CI: 0.15%-1.24%) respectively in patients receiving invasive diagnosis and treatment and remained to be ≤0.25% in volunteer blood donors, people receiving physical examination and clients visiting family planning outpatient clinics. Results for the comparison of the anti-HCV positive rates in the 5 populations indicated that the differences were significant (F=23.091, P<0.001 in 2016 and F=20.181, P<0.001 in 2017). Conclusions: Data from the sentinel surveillance of HCV infection on prevalence in China showed that the anti-HCV positive rates varied in the 5 populations during 2016-2017. The anti-HCV positive rate appeared the highest in the hemodialysis patients, followed by that in the patients receiving invasive diagnosis and treatment, and the prevalence of HCV infection in other 3 populations were at low levels.

Abstract
Objective: To analyze the related factors of diabetic nephropathy in inpatients with type 1 diabetes mellitus (T1DM). Methods: A total of 300 patients with T1DM who were treated in the Department of Endocrinology of Anhui Provincial Hospital between 2014 and 2016 were analyzed retrospectively. All the patients were divided into two groups according to their urine albumin-to-creatinine ratio: non-diabetic nephropathy group (n=193) and diabetic nephropathy group (n=107). Multivariate logistic regression analysis was adopted to analyze the factors related to diabetic nephropathy in T1DM, including the age, diabetic duration, body mass index (BMI) and glycosylated hemoglobin (HbA1c) of the two groups. Results: Age, diabetes duration, HbA1c, systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol, triglyceride and uric acid (UA) of diabetic nephropathy group were higher than those of non-diabetic nephropathy group (all P<0.05). The total bilirubin, hemoglobin (Hb) and albumin in non-diabetic nephropathy group were higher than those in diabetic nephropathy group (P<0.05). The proportion of women in diabetic nephropathy group was higher than non-diabetic nephropathy group (62.6% vs 42.0%, P=0.001). Multivariate logistic regression analysis showed that diabetes duration (OR=2.142, 95% CI: 1.011-4.539), HbA1c (OR=1.262, 95% CI: 1.090-1.462), DBP (OR=1.048, 95% CI: 1.001-1.096), UA (OR=1.005, 95% CI: 1.001-1.009) and Hb (OR=0.952, 95% CI: 0.929-0.975) were independent related factors for diabetic nephropathy. Conclusions: Positive controlling of blood pressure, blood glucose, hyperuricemia and correcting anemia may reduce the incidence of diabetic nephropathy in T1DM patients.

Abstract
The purposes of this study were to evaluate the expression of retinol-binding protein 4 (RBP4) in diabetic rats with atherosclerosis and to investigate the role of vitamin D intervention. Male Wistar rats were randomly divided into 4 groups, including the control group (NC), the diabetic rats (DM1), the untreated diabetic atherosclerosis rats (DM2), and the vitamin D-treated diabetic atherosclerosis rats (DM3). The levels of serum and adipose RBP4, fasting insulin (FINS), fasting plasma glucose (FPG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-c), triglycerides (TG), low-density lipoprotein cholesterol (LDL-c), 25-hydroxyvitamin D [25(OH)D], C-reactive protein (CRP), and systolic blood pressure (SBP) were measured. Homeostasis model assessment of insulin resistance (HOMA-IR), homeostasis model assessment β-cell function index (HOMA-β), and atherogenic indexes (AI) were calculated. Compared with group NC, the levels of RBP4, TG, LDL-c, FPG, FINS, CRP, AI1, AI2, SBP, and HOMA-IR increased, while the levels of HDL-c, 25(OH)D, and HOMA-β decreased in groups DM1 and DM2. After 8 weeks of vitamin D supplementation in group DM3, the levels of 25(OH)D and HOMA-β increased and the levels of LDL-c, TC, HOMA-IR, FINS, CRP, RBP4, AI1, AI2, and SBP decreased significantly when compared with group DM2 (P < 0.05); Pearson analysis showed that serum RBP4 was positively correlated with TG, FINS, HOMA-IR, SBP, CRP, and AI and negatively correlated with 25(OH)D. In addition, multivariable logistic regression analysis showed that serum RBP4, SBP, and HDL-c were predictors for the presence of diabetic atherosclerosis. These findings suggested that RBP4 could involve in the improvement of diabetic atherosclerosis; vitamin D had the ability to decrease the level of RBP4 and eventually played an important role in preventing atherosclerosis in diabetes.

Abstract
Objective: To analyze factors influencing antiretroviral therapy (ART) adherence among human immunodeficiency virus (HIV) patients receiving ART at the town level in Ili Kazakh Autonomous Prefecture (Ili) in May 2015 and to document enhanced ART for acquired immunodeficiency syndrome (AIDS) cases. Methods: A cross-sectional survey was conducted using one-on-one interviews and data collection from the system of AIDS follow-up management in three ART services centers at the town level of Ili. The subjects were HIV-infected individuals, aged 18 years or older, who were receiving ART during the survey. The surveys collected demographic characteristics, information related to ART and status of engaging ART, smoking and drinking behavior, depression, and quality of life. Results: A total of 412 participants completed the survey. The age was (41.1±8.0) years (range, 19-67 years). Approximately 60.9% (251) were male and 39.1% (161) were female. The survey showed that 75.0% (309) of participants were in good adherence and the P(50) (P(25), P(75)) of quality of life was 56.31 (50.55, 59.42). Females demonstrated better adherence to ART (82.6% (n=133)) than males (70.1% (n=76)) (χ(2)=8.16, P=0.005). The compliance rate of participants (78.0% (n=54)) with depression was higher than non-depressed participants (63.5% (n=255)) (χ(2)=7.52, P=0.008). Multivariate logistic regression analyses showed that the probability of good adherence to ART increased with increasing quality of life (OR=1.06, 95%CI:1.02-1.09). Moreover, participants who consumed alcohol or disclosed their HIV infection status to families were less likely to have good adherence to ART (OR=0.26, 95% CI:0.13-0.53 and OR=0.31, 95% CI:0.13-0.72, respectively). Additionally, employed participants were also less likely to have good adherence to ART compared with unemployed participants (OR=0.45, 95% CI:0.21-0.97). Conclusion: HIV/AIDS patients primarily showed good adherence to ART. Factors related to ART adherence included alcohol consumption, informing family of infection, work status, and quality of life.

Abstract
OBJECTIVE To investigate adherence and the influence factors among patients who are on antiretrovirus therapy (ART) of 3 provinces in China. METHODS This study selected 18-year-old and older AIDS patients as the survey objects who initiated anti-retrovirus therapy between April and September of 2014 and kept on the treatment for one year in Yunnan,Sichuan,and Hu'nan province. Information of demography, treatment and social support was collected by questionnaires. Adopt SSRS questionnaire to calculate the information of objective support, subjective support and utilization of social support. χ(2) test and logistic regression were performed to examine relationships between factors and adherence. RESULTS A total of 386 patients with medication were investigated. Among them, there were 365 (94.6%) cases who were compliant to the ART, and 357 (92.5%) cases can take their pills on time, and 29 (7.5%) cases take their medication in excess of the prescribed time more than two hours. Social support score was 27.2 ± 7.3, including objective support score (5.6 ± 2.7), subjective support score (16.1 ± 4.8), and utilization of social support (5.5 ± 1.9). Multivariate logistic regression analysis revealed that adherence was significantly associated with the correct cognition of medication (OR (95%CI): 3.24 (1.17-9.00)), the self-awareness of the drug regimen was not complexity (OR (95%CI): 9.34 (3.27-26.68)), taking medication 1 time a day (OR (95%CI): 4.00 (1.35-11.84)), and the batter utilization of social support (OR (95%CI): 1.49 (1.06-2.01)). Married/cohabiting or farmers tend to be nonadherenced, while the OR (95%CI) was 0.24 (0.08-0.67) and 0.23 (0.08-0.69), respectively. CONCLUSION The patients among these provinces were compliant to the ART, and most of them can take their pills on time. The social support score of these patients was lower than normal person. Participants who have correct cognition of medication, thinking their drug regimen was not complexity; Taking medication 1 time a day or have high level of utilization of social support showed a significantly higher level of self-reported adherence.

Abstract
The aim of the current study was to investigate the effects and mechanism of metformin in oxidative stress and p38 mitogen-activated protein kinase (p38MAPK) expression in rat glomerular mesangial cells (MCs) cultured in a high glucose medium. Rat glomerular MCs (HBZY-1) were cultured in complete medium and divided into the following five groups: Normal control (NC), high glucose (HG), metformin-treated, SB203580-treated (SB) and N-acetylcysteine-treated (NAC). The production of intracellular reactive oxygen species (ROS) in rat glomerular MCs was measured using flow cytometry. Superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in the supernatant was detected using colorimetric analysis and an ELISA, respectively. p22phox mRNA levels in rat glomerular MCs were determined using reverse transcription-quantitative polymerase chain reaction. The levels of p22phox protein and phosphorylated p38 mitogen-activated protein kinase (p-p38MAPK) protein in rat glomerular MCs were determined by western blot analysis. Compared with the NC group, the activity of SOD in the supernatant was significantly reduced, whereas the levels of MDA in the supernatant, intracellular p22phox mRNA and protein, p-p38MAPK protein in addition to ROS production in rat glomerular MCs were significantly increased in the HG group (P<0.05). When metformin was added to the high glucose medium, the activity of SOD in supernatant fluid was increased significantly, whereas a significant reduction (P<0.05) was observed in the levels of MDA in the supernatant, intracellular p22phox mRNA and protein, p-p38MAPK protein in addition to ROS production in rat glomerular MCs. These results were similar to those obtained when SB203580 or N-acetylcysteine was added to the high glucose medium (P<0.05). In conclusion, metformin was suggested to alleviate high glucose-induced oxidative stress and p-p38MAPK protein expression in rat glomerular MCs, which may contribute to its reno‑protective abilities in diabetes.

Abstract
The aim of this study was to explore the relationship between serum 25-hydroxyvitamin D [25(OH)D] concentrations and lower extremity arterial disease (LEAD) in type 2 diabetes mellitus (T2DM) patients and to investigate the intervention effect of vitamin D. 145 subjects were assigned to a control group (Group NC), T2DM group (Group DM1), and T2DM complicated with LEAD group (Group DM2); then Group DM2 were randomly divided into Group DM3 who received oral hypoglycemic agents and Group DM4 who received oral hypoglycemic drugs and vitamin D3 therapy. Compared to Group NC, 25(OH)D was significantly lower in Group DM2 and marginally lower in Group DM1. In contrast to baseline and Group DM3, 25(OH)D rose while low density lipoprotein (LDL), retinol binding protein 4 (RBP4), and HbA1c significantly lowered in Group DM4. Statistical analysis revealed that 25(OH)D had a negative correlation with RBP4, duration, HbA1c, homeostasis model assessment for insulin resistance (HOMA-IR), and fasting plasma glucose (FPG). LDL, systolic blood pressure (SBP), FPG, and smoking were risk factors of LEAD while high density lipoprotein (HDL) and 25(OH)D were protective ones. Therefore, we deduced that low level of 25(OH)D is significantly associated with the occurrence of T2DM complicated with LEAD.

Abstract
BACKGROUND AND AIMS The objective of this study is to observe the effect of alpha-lipoic acid (ALA) on Pod injury by anti-inflammation and explore its possible renal protective mechanism. METHODS A total of 36 cases with type 2 diabetes with microalbuminuria and fasting plasma glucose (FPG) levels less than 9 mmol/L and glycated hemoglobin A1c (HbA1c) ≤9.0 % were recruited to be treated with ALA (600 mg, daily) for 6 months (group DA). Another 30 healthy individuals were chosen as normal controls (group NC). The levels of serum creatinine (Cr), FPG, and HbA1c were detected; blood pressure was recorded; and early morning urine samples (corrected for urinary Cr) were collected for the examination of urinary monocyte chemoattractant protein-1 (MCP-1), transforming growth factor-β1 (TGF-β1), podocalyxin (PCX), nephrin, albumin and Cr in group NC and group DA at the baseline and the sixth month. RESULTS The excretions of urinary MCP-1, TGF-β1, PCX, nephrin and albumin to Cr ratio (abbreviated as UMCR, UTCR, UPCR, UNCR and UACR respectively) were significantly increased in group DA compared with group NC (all P < 0.01), and after 6-month treatment, all indexes mentioned above decreased markedly (P < 0.05), while FPG and HbA1c had no obvious changes. Additionally, there was a positive correlation between UMCR, UTCR with UPCR, UNCR and UACR, respectively (all P < 0.01). CONCLUSIONS Anti-inflammation of ALA in vivo and local kidney is implicated in the protection of glomerular Pod injury in patients with type 2 diabetes.

Abstract
BACKGROUND Oxidative Stress and p38 mitogen-activated protein kinase (p38MAPK) play a vital role in renal fibrosis. Pioglitazone can protect kidney but the underlying mechanisms are less clear. The purpose of this study was to investigate the effect of pioglitazone on oxidative stress and whether the severity of oxidative stress was associated with the phosphorylation level of p38MAPK. METHODS Rat mesangial cells were cultured and randomly assigned to control group, high glucose group and pioglitazone group. After 48-hour exposure, the supernatants and cells were collected. The protein levels of p22(phox), p47(phox), phosphorylated p38MAPK, total p38MAPK were measured by Western blotting. The gene expressions of p22(phox), p47(phox) were detected by RT-PCR. The levels of intracellular reactive oxygen species (ROS) were determined by flow cytometry. The levels of superoxide dismutase (SOD) and maleic dialdehyde (MDA) in the supernatant were determined respectively. RESULTS Compared with the control group, the expression levels of p22(phox), p47(phox), phospho-p38 and ROS significantly increased, activity of SOD decreased in high glucose group, while the level of MDA greatly increased (P < 0.01). Pioglitazone significantly suppressed p22(phox), p47(phox) expressions and oxidative stress induced by high glucose. The expressions of p22(phox), p47(phox), phospho-p38MAPK and ROS generation were markedly reduced after pioglitazone treatment (P < 0.05). The activity of SOD in the the supernatant increased (P < 0.05), while the level of MDA decreased greatly by pioglitazone (P < 0.05). The level of oxidative stress was associated with the phosphorylation level of p38MAPK (P < 0.01). CONCLUSION Pioglitazone can inhibit oxidative stress through suppressing NADPH oxidase expression and p38MAPK phosphorylation.

Abstract
Cathepsin S (CatS), a proteolytic enzyme, which belongs to the cysteine proteinase family, is associated with atherosclerosis, coronary heart disease, cancer and other diseases. The present study aimed to explore the correlation between serum CatS and insulin resistance (IR) in patients with type 2 diabetes. A total of 51 patients with type 2 diabetes (Group DM) were recruited for this study and 49 healthy individuals were selected as normal controls (Group NC). Blood pressure and body mass index (BMI) were recorded, and serum creatinine, CatS, glycosylated hemoglobin (HbA1c), lipid and insulin levels, and fasting plasma glucose (FPG) levels were measured in all the participants. The homeostatic model assessment index of IR (HOMA-IR) was calculated according to FPG and serum insulin levels. Serum CatS, very low density lipoprotein (VLDL) and triglyceride (TG) levels in Group DM were significantly higher compared with those in Group NC (P=0.000, 0.014 and 0.020, respectively). Significantly positive correlations were identified between CatS levels and VLDL and TG levels, respectively (P<0.05 for both); however, no significant correlations were determined between CatS levels and age, course of disease, blood pressure, cholesterol, BMI, FPG, HbAc1 and HOMA-IR (P>0.05). Further stratification analysis showed that CatS had no association with IR at different HOMA-IR and HbA1c levels. The present study demonstrated that serum CatS, which was significantly increased in patients with type 2 diabetes, had no correlation with IR. This indicates that CatS and IR are independent of each other; however, the precise mechanisms require further investigation.

Abstract
Aspirin and its main metabolite salicylate are widely used to relieve pain, treat inflammatory diseases, and prevent ischemic stroke. Multiple pathways are responsible for the therapeutic actions exerted by these drugs. One of the pathways is targeting neuronal receptors/ion channels in the central nervous system. Correspondingly, increasing evidence has implicated acid-sensing ion channels (ASICs) in the processes of the diseases that are medicated by aspirin and salicylate. We therefore employed whole-cell patch-clamp recordings to examine the effects of salicylate as well as aspirin on ASICs in cultured cortical neurons of the rat. We recorded rapid and reversible inhibition of ASIC current by millimolar concentrations of aspirin and salicylate and found that salicylate reduced acidosis-induced membrane depolarization. These data suggest that ASICs in the cortex are molecular targets of high doses of aspirin and salicylate. In addition, the results from lactate dehydrogenase release measurement showed that high doses of aspirin and salicylate protected the cortical neuron from acidosis-induced neuronal injury. These findings may contribute to a better understanding of the therapeutic mechanisms of aspirin and salicylate actions in the brain and provide new evidence on aspirin and salicylate used as neuroprotective agents in the treatment of ischemic stroke.

Abstract
OBJECTIVE To observe the effects of hydrochloride pioglitazone on urinary cytokine excretion in type 2 diabetes and to explore its possible reno-protective mechanisms. DESIGN Subjects and Methods. Ninety-eight patients with type 2 diabetes and a fasting blood glucose (FBG) levels between 7.0 and 13.0 mm and glycated haemoglobin A1c (HbA1c) ≥ 7.0% were assigned randomly to receive either the pioglitazone (DP group) or a sulphonylurea (DS group). Another 49 healthy individuals were chosen as normal controls (group NC). At the start of the study and after 12 weeks of treatment, urinary cytokines including monocyte chemoattractant protein-1 (MCP-1), transforming growth factor-β1 (TGF-β1) and vascular endothelial growth factor were measured and were expressed as a ratio of urinary creatinine excretion. Urinary albumin/creatinine ratio, FBG and HbA1c were determined at the same time. RESULTS The excretion of each urinary cytokine, corrected for urinary creatinine, was significantly increased in both groups of patients with diabetes, compared with normal controls, and after a 12-week treatment were significantly decreased by both therapies but the effect of pioglitazone was statistically greater than with sulphonylureas. Urinary albumin/UCr and both systolic and diastolic blood pressure were decreased significantly by pioglitazone (P < 0.01 or P < 0.05) but not by sulphonylurea treatment (P < 0.05), while there was no significant difference in FBG or HbA1c between two groups. There was a positive correlation between the excretion of cytokines and urinary albumin /UCr (all P < 0.01). CONCLUSIONS This study indicates that pioglitazone reduces urinary albumin excretion by a mechanism that is at least partly independent of blood sugar control. The correlation of urinary albumin excretion with improvement in urinary cytokines suggests that this reno-protective effect of piogliazone in diabetes may be related to local reduction in cytokine activity within the kidney.

Abstract
BACKGROUND Thiazolidinediones (TZDs) exert a number of direct reno-protection beyond its hypoglycaemic effect in type 2 diabetics, which may be partly related to its anti-fibrosis and anti- inflammatory action. MATERIALS AND METHODS A total of 98 type 2 diabetics with fasting blood glucose (FBG) between 7.0 and 13.0 mmol L(-1) and glycated haemoglobin A1c (HbA1c) > or = 7.0% were randomly assigned to add pioglitazone (group DP) or sulfonylurea (group DS) for 12 weeks. FBG, HbA1c, serum creatinine (SCr) and blood urea nitrogen (BUN), and urinary TGF-beta1, albumin (UALB) and creatinine (UCr) were determined at the basal and the 12th week. RESULTS Fasting blood glucose, HbA1c and urinary TGF-beta1/UCr ratio (UTCR) were obviously decreased in both groups after 12 weeks treatment; UALB/UCr ratio (UACR) decreased obviously in group DP (P < 0.01), while slightly in group DS. UACR and UTCR in group DP were significantly lower than those in group DS after treatment, while FBG and HbA1c had no statistical differences between the two groups. In addition, UTCR had positive correlation with UACR (r = 0.367, P < 0.01). CONCLUSIONS Pioglitazone decreases urinary TGF-beta1 excretion in type 2 diabetics, which may be partly contributed to its direct reno-protection.

Abstract
BACKGROUND Nowadays, intensive insulin treatment has been widely used in type 2 diabetics who have poor control of blood glucose, to reduce the risk of chronic complications of diabetes. Recently, some scholars have paid more attention to the pivotal role of inflammation involved in type 2 diabetes and its complications. Monocyte chemoattractant protein-1 (MCP-1) and intercellular adhesion molecule-1 (ICAM-1), which are two important inflammatory chemokines, have been documented to participate in the onset and development of type 2 diabetes and its complications, such as diabetic nephropathy (DN). DESIGN In the current study, we recruited 30 type 2 diabetics with microalbuminuria to be treated with multiple insulin injections daily for 2 weeks. Random spot urine samples (corrected for creatinine-Cr) were collected for the examination of urinary MCP-1, ICAM-1 and albumin (Alb) levels before and after the intensive insulin therapy. Changes in their levels were observed to test the hypothesis that type 2 diabetes with microalbuminuria is associated with elevated urinary concentrations of MCP-1 and ICAM-1, and intensive insulin therapy can result in a decline of Alb by reducing the inflammatory reaction. RESULTS The urinary MCP-1/Cr and urinary ICAM-1/Cr ratios in type 2 diabetic patients with microalbuminuria were much higher than those in normal controls, and intensive insulin treatment could decrease significantly the urinary MCP-1/Cr, ICAM-1/Cr and Alb/Cr ratios in type 2 diabetics with microalbuminuria. CONCLUSION Intensive insulin treatment may protect against renal injury in early DN by reducing the urinary MCP-1 and ICAM-1 excretions.

Abstract
A novel solid-state fermentation apparatus, namely an upright multi-tray conidiation chamber, was developed to facilitate the production of aerial conidia of fungal biocontrol agents, such as Beauveria bassiana. The chamber with 25 bottom-meshed metal trays had a capacity of > or =50 kg rice with each tray holding > or =2 kg. In repeated trials, a mean yield of 2.4 (1.8-2.7) x 10(12) conidia kg(-1) rice was harvested from the 7-day cultures of B. bassiana in a fully loaded chamber. The new apparatus has a high potential for bulk production of fungal conidia.

Abstract
This study aimed at the exploration of the relationship between Na(+)-H+ exchange system and myocardial ischemia-reperfusion injury (MRI) in an attempt to provide a theoretic basis for the prevention and treatment of MRI. We used the isolated working guinea pig hearts as the experimental model to mimick cardiopulmonary bypass, which included 120 min hypothermic ischemic cardioplegic arrest followed by 60 min normothermic reperfusion. The hearts were divided into 2 groups: the control group receiving St. Thomas' Hospital Solution (STS) and the treated group receiving STS + amiloride, a Na(+)-H+ exchange blocker. The results showed that during reperfusion, [Na+]i and [Ca2+]i overloads, poor recovery of cardiac function, increases in CPK release and OFR generation, reduction of ATP content and serious damage of ultrastructure were seen in group 1; whereas there were no [Na+]i and [Ca2+]i overloads and better recovery of cardiac function accompanied by improved results of biochemical assay and less damage of ultrastructure was found in group 2. Our study indicates that amiloride can inhibit Na(+)-H+ exchange system in cardiac cells during early reperfusion period, which prevents [Na+]i overload produced by Na(+)-H+ exchange, and stops Na(+)-Ca2+ exchange activated by high level of [Na+]i, thus attenuating [Ca2+]i overload caused by Na(+)-Ca2+ exchange and myocardial injury. Therefore, we conclude that Na(+)-H+ exchange blocker, amiloride, can exert significant protective effects on MRI and its use may prove to be a new clinical approach to prevention and cure of MRI.

Abstract
The present study was undertaken to evaluate the improved protection of antegrade aortic root perfusion combined with intermittent coronary sinus occlusion (APCSO) for the 1-hour ischemic myocardium in the presence of left anterior descending artery occlusion, 12 dogs were divided into 2 groups: anteperfusion (AP) alone (n = 6) and APCSO (n = 6). The experimental results showed that APCSO provided a better cardioplegic distribution and a lower hypothermia (15.6 degrees C versus 17.2 degrees C) in the occluded LAD region, compared with AP. After ischemia, cardiac index and left ventricular stroke index recovered excellently in APCSO (128% to 141% and 115% to 158% of preischemic values, respectively), and much worse in AP (69% to 82% and 53% to 73% of preischemic values, respectively). Our study has confirmed that APCSO is superior to AP in myocardial protection in the presence of coronary artery occlusion.
