Objective To evaluate the efficacy and safety of efavirenz-based therapy in patients with human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infection. Methods Fiftythree HIV/HCV co-infected patients received efavirenz-based therapy were followed up for 7 years.The changes of CD4+ T lymphocyte count, HIV virus load, hepatic function, hepatic fibrosis index,blood lipid, blood glucose, blood uric acid and blood routine were observed. The comparison of means before and after treatment was performed by t-test. Results The HIV RNA levels at baseline and endpoint were (4. 56±0. 88) lg copy/mL and (1.70±1.10) lg copy/mL, respectively (t=14. 781, P<0.01). The peripheral blood CD4+ T lymphocyte counts were ( 188.37±151.14)×106/L and (445.18±314.25)×106/L, respectively (t=5.362, P<0.01).The alanine aminotransferase (ALT) levels were (36.6±16.3) U/L and (57.2±9.9) U/L, respectively (t=7.864, P<0. 01).The glycocholic acid levels were (444.22±476.74) mg/L and (556.88±733.05) mg/L, respectively (t=0.938, P<0.05). The Ⅳ-collagen(Ⅳ-C) levels were (45.13±8.25) ng/mL and (47.88±4.51) ng/mL, respectively (t= 2.129, P<0.05). The riacylglycerol levels were (1.57±0.65)mmol/L and (2.51±1.29) mmol/L, respectively (t=4.737, P<0.01). The blood uric acid levels were (298.5±48.2) mmol/L and (495.1±89.4) mmol/L, respectively (t= 14.092, P<0.01).Conclusions The efavirenz-based therapy is efficacious in HIV/HCV co-infected patients, but it could cause liver injury and metabolic disorder.

Objective:To observe the effects of intervention based on self-regulation mode on illness perception, medical coping styles and quality of life of patients with psoriasis.Methods:Eighty patients with psoriasis from February 2018 to August 2019 in Qinhuangdao First Hospital were selected and divided into two groups by random digits table method, 40 patients in each group. The control group was given routine intervention, and the experimental group was given intervention based on self-regulation mode. The Illness Perception Questionnaire-Revised (IPQ-R) scores, Medical Coping Modes Questionnaire (MCMQ) scores, dermatologylifequalityindex (DLQI) scores and compliance of the two groups were compared before and after intervention.Results:There was no significant difference in the score of IPQ-R, MCMQ, DLQI before intervention between the two groups( P>0.05). After intervention, scores of symptoms, disease perception and causes of the disease in IPQ-R were (7.24±0.75), (162.34±20.35), (76.23±8.65) points in the experimental group and (6.08±0.72), (123.26±18.57), (52.79±7.84) points in the control group, there were significant differences between the two groups ( t values were 7.057, 8.972, 12.699, P<0.01). In the MCMQ, facing score,avoidance score and yielding score were (25.67±2.83), (12.26±1.84), (9.12±1.24) points in the experimental group, (21.76±3.89), (14.35±2.48), (10.45±1.68) points in the control group, there were significant differences between the two groups ( t values were 5.141, -4.280, -4.028, P<0.01). The DLQI scores of experimental group were significantly higher than those of control group ( t values were 2.648-8.244, P<0.05 or 0.01), and compliance of experimental group (97.5%, 39/40) was significantly better than control group (80.00%, 32/40) with statistically significant( Z value was 40.000, P<0.01). Conclusions:Intervention based on self-regulation mode can effectively reduce negative emotions of patients with psoriasis, increase their illness perception and compliance, improve their medical coping styles, self-management ability and quality of life, with positive application value.

Objective:To study the changes in long non-coding RNA C2dat1 expression in kidney tissues of rats at different stages of diabetic kidney disease (DKD) and its relationship with renal interstitial fibrosis.Methods:Forty-eight male SD rats were randomly divided into two groups with 24 rats in each group: control group and DKD group. The rats in the control group were fed with ordinary diet, while those in the DKD group were fed with high-fat diet and drank water freely. After eight weeks of feeding, the rats were fasted for 12 h with free access to water. Then, the DKD group was given a one-time intrabitoneal injection of streptozotocin and the control group was given an equal dose of sodium citrate buffer. After 72 h, the random peripheral blood glucose concentration (≥ 16.7 mmol/L for three consecutive days) and urine sugar (positive) were tested to assess the establishment of the diabetes model. Urine, blood and kidney samples were collected at 3, 6, 9 and 12 weeks. The urinary protein excretion rate within 24 h, urinary creatinine and serum total cholesterol were measured by automatic biochemical apparatus. Pathological changes in kidney tissues were observed by HE staining. The expression of calcium/calmodulin-dependent protein kinase Ⅱ delta (CaMK2D), p65, p50, α-SMA and E-cardherin was detected by immunohistochemistry. Quantitative real-time PCR (qPCR) was used to detect the expression of lncRNA C2dat1 and CaMK2D. The relationship of lncRNA C2dat1 with α-SMA, E-cardherin and CaMK2D was analyzed by correlation analysis. In in vitro experiment, renal tubular epithelial cells HK-2 were induced by high glucose. The expression of lncRNA C2dat1 and CaMK2D in HK-2 cells was detected by qPCR after 24, 48 and 72 h of intervention. Results:The rats in the DKD group showed typical symptoms such as polydipsia, polyphagia, significant weight loss and increased blood glucose as compared with the rats in the control group. Results of the biochemical tests revealed that compared with the control group, the DKD group had increased 24 h excretion rate of urinary protein, decreased urinary creatinine and up-regulated total cholesterol. HE staining showed that the rats in the control group had intact glomeruli, normal basement membrane and no mesangial hyperplasia or inflammatory cell infiltration. However, enlarged glomeruli and evenly thickened basement membrane were observed in the DKD group. Immunohistochemistry indicated that the expression of CaMK2D, p50 and α-SMA was higher in the DKD group than in the control group, while the expression of E-cardherin was lower in the DKD group. qPCR results showed that the expression of lncRNA C2dat1 and CaMK2D at mRNA level was higher in the DKD group than in the control group. In in vitro experiment, the expression of lncRNA C2dat1 and CaMK2D at mRNA level was also higher in HK-2 cells induced by high glucose than in the control group. Correlation analysis indicated that lncRNA C2dat1 was positively correlated with α-SMA and CaMK2D, but negatively correlated with E-cardherin. Conclusions:During the progression of DKD, the high expression of lncRNA C2dat1 might promote diabetic renal interstitial fibrosis by regulating the expression of CaMK2D to activate the NF-κB signaling pathway.
