One hundred and sixty non-diabetic patients with cerebral ischemia of primary onset were enrolled in the study. The patients were divided into impaired glucose tolerance (IGT) group and normal glucose tolerance (NGT) group according to the oral glucose tolerance test (OGTT). Carotid atherosclerosis and carotid artery stenosis were examined with vascular Doppler ultrasonic detection. The incidence rates of carotid atherosclerosis in IGT group and NGT group were 87. 5% (70/80)and 63.8% (51/80)respectively (χ2= 12.240,P <0.001);the incidence rates of carotid stenosis in IGT group and NGT group were 63.8% (51/80) and 47. 5 % (38/80), respectively(χ2 =4. 279, P =0. 039);the degree of carotid artery stenosis in IGT group was higher than that in NGT group(χ2= 21.95, P < 0. 01). The results indicate that IGT may be related to atherosclerosis and stenosis of carotid artery in cerebral ischemic patients.

Objective To investigate the expression and role of β-catenin in small-for-size liver grafts during early stage of liver regeneration after liver transplantation in rats.Method The livers of male Sprague-Dawley rats were reduced to 30％ or 50％ of their original sizes and transplanted.The experiment was divided into 3 groups:small-for-size graft group (SSG),half-size graft group (HSG) and sham-operated group.Liver samples were harvested at various time points after transplantation (n =6 per time point) for Western blotting and immunohistochemistry.Six rats in each group were sacrificed at 3rd day after liver transplantation for estimating liver regeneration rate.Result Liver regeneration rate in SSG group was lower than that in HSG group.The expression of β-catenin was down-regulated in liver graft of both groups after being stored in cold Ringer solution for 2 h.The expression of β-catenin was significant up-regulated in HSG group from 5 min to 12 h after operation,while the down-regulated expression of β-catenin was persisted in SSG group at 5 min after operation,and mildly increased expression of β-catenin occurred at 2 h and 6 h,which was significantly lower than that in HSG group at the corresponding time points.The expression of active-β-catenin was low in each group before transplantation.Significant expression of active-β-catenin was found at 5 min in HSG group and persisted until 12 h after operation,mildly increased expression of active-β-catenin in SSG group was only found at 2 h,which was lower than that in HSG group at the same time points.Immunohistochemical staining revealed that β-catenin was mainly expressed on the hepatocyte membrane and in cytoplasm in the sham-operative group,many hepatocytes exhibited nuclear localization of β-catenin in HSG group from 5 min to 24 h,while only some hepatocytes exhibited nuclear localization of β-catenin in SSG group.The expression of Cyclin D1 in SSG group was significantly lower than that in HSG group,which was similar to the expression of C-Myc.Conclusion Attenuated activation of Wnt/β-catenin signaling and down-regulated expression of target genes during early regeneration of small-for-size liver grafts may be involved in the inhibition of liver regeneration of small for size liver grafts.

Objective:To analyze the mental health status of men who have sex with men (MSM) population among acquired immunodeficiency syndrome (AIDS) patients.Methods:A face-to-face questionnaire survey was conducted to investigate the general information, symptom check list-90 (SCL-90) questionnaire and scale of 269 MSM patients with AIDS in the Eighth Hospital of Xi'an city from November 2015 to May 2016.Results:Among the 269 cases of MSM with human immunodeficiency virus (HIV)/AIDS, the majority were 20-40 years old, with higher education level, mostly unmarried and nonsingleton. The scores of each factor of SCL-90 were significantly higher than that of the norm, among which diet and sleep, interpersonal relationship, anxiety and depression were the most prominent; regression analysis showed that the main reason affecting the scores of each factor among AIDS patients was the low quality of life, and the patients with high education were more likely to have depression and anxiety.Conclusions:MSM has its own special characteristics among AIDS patients, and there are many psychological problems. Necessary psychological intervention measures should be given.

Objective:To compare the efficacy and safety of oral terbinafine versus itraconazole in the treatment of pediatric tinea capitis.Methods:From January 2021 to December 2021, a randomized clinical trial was conducted among 53 children with tinea capitis in Beijing Children′s Hospital. These patients were randomly divided into 2 groups by using a random number table: terbinafine group treated with oral terbinafine at different doses (weight <20 kg, dose: 62.5 mg/d; weight 20 - 40 kg, dose: 125 mg/d; weight >40 kg, dose: 250 mg/d), while itraconazole group treated with oral itraconazole at doses of 3 - 5 mg·kg -1·d -1. Statistical analysis was performed using the SPSS 23.0 software, and enumeration data were compared between groups by using chi-square test or Fisher′s exact test. Results:Totally, 27 patients were treated with oral terbinafine, including 17 with tinea alba and 10 with kerion; 26 were treated with oral itraconazole, including 17 with tinea alba and 9 with kerion. After treatment, 14 (51.85%) patients were cured in the terbinafine group, including 5 with tinea alba and 9 with kerion, while 25 (96.15%) were cured in the itraconazole group, including 16 with tinea alba and 9 with kerion. The response rate was significantly higher in the itraconazole group than in the terbinafine group ( χ2 = 13.37, P < 0.001) . Conclusion:The efficacy of itraconazole was superior to that of terbinafine in the treatment of pediatric tinea alba, but their efficacy was equivalent in the treatment of pediatric kerion.

OBJECTIVE： To investigate the situation and problems of clinical microecological preparations in pediatrics department of China， and to provide reference for rational application of microecological preparations in children. METHODS： Outpatient/emergency prescriptions of microecological preparations during Jan.-Mar. 2019 were retrieved from information system of 5 “Third Grade Class A” children hospitals， and were investigated and analyzed in respects of the type of microecological agents， age distribution， clinical diagnosis， drug combination， off-label medication， etc. RESULTS： A total of 74 210 outpatient/emergency prescriptions were collected， involving 18 kinds of microecological preparations. Among them， Clostridium butyricum combined viable powder ranked first （31 146， accounting for 41.97％）， followed by Brucella yeast powder （14 289， accounting for 19.25％） and Compound Lactobacillus acidophilus tablets （10 281， 13.85％）. The age of children was less than 18 years old， and the proportion of children aged 1-＜3 years old was the highest （33 753， 45.48％）. The most common clinical diagnosis     was digestive tract diseases （54 009， 72.78％）， followed    by respiratory infectious diseases （11 744， 15.83％）. In combination with microecological agents， there were Chinese patent medicine for invigorating the spleen and stomach     （18 546， 24.99％）， antibacterial medicine （10 595， 14.28％） and oral rehydration salt Ⅲ （8 238， 11.10％）. Off-label drug use was found in 19 532 prescriptions （26.32％）， mainly manifesting as super-indications （15 590， 21.01％）， super-usage and dosage （8 098， 14.52％）， super crowd medication （48， 3.91％） was found in a few prescriptions. CONCLUSIONS： There is a high incidence of off-label use of microecological agents in children. Medical staff should standardize prescription behavior and promote rational use of drugs. At the same time， the improvement of the information of children’s medication in drug instructions to ensure the safety and effectiveness of children’s medication should be encouraged.

OBJECTIVETo explore the effect of the autoantibody against the β3-adrenoceptor on rats with experimental heart failure.

METHODThe peptide corresponding to the sequence of β3 adrenoceptor was synthesized to actively immunize the rats, ELISA was used to detect the serum level of autoantibody against the β3-adrenoceptor (β3AA). Total IgGs were extracted from the serum containing β3AA in immunized rats. Aortic banding surgery was used to establish the heart failure model in male Wistar rats and rats were divided into the sham group (n = 8), heart failure group(n = 8),β3AA-immunized heart failure group (HF+β3AA, n = 8) and corresponding negative IgG-immunized heart failure group (HF+ IgG, n = 8).In 6 weeks and 8 weeks after aortic banding surgery, the serum levels of NT-pro brain natriuretic peptide (NT-proBNP) were assayed with ELISA assay and cardiac function was assessed by echocardiography.

RESULTSβ3AA was used to immunize rat with heart failure, the serum level of β3AA was stable at 50 days post immunization. At 8 weeks after aortic banding surgery, heart failure group showed significantly increased LVEDD [(6.92 ± 0.22) mm vs.(5.62 ± 0.19) mm, P < 0.001], LVESD [(4.63 ± 0.23) mm vs.(3.50 ± 0.20) mm, P < 0.01] and IVS [(2.44 ± 0.06) mm vs.(2.28 ± 0.05) mm, P < 0.05], and decreased LVEF[(62.07 ± 3.99)% vs.(79.63 ± 3.02)%, P < 0.01] and LVFS [(31.46 ± 3.22)% vs.(43.65 ± 2.68) %, P < 0.05] compared with the sham group.HF+β3AA IgG group showed decreased LVEDD [(6.07 ± 0.30) mm vs.(6.92 ± 0.24) mm, P < 0.05] and LVESD [(3.92 ± 0.22) mm vs.(4.68 ± 0.23) mm, P < 0.05], and higher LVEF [(70.29 ± 1.78)% vs.(61.95 ± 3.03)%, P < 0.05] and LVFS [(38.08 ± 2.32)% vs.(30.50 ± 1.82)%, P < 0.05] compared to the HF+ IgG group.In addition, compared with the HF+ IgG group, HF+β3AA IgG group showed decreased serum levels of NT-proBNP [(196.43 ± 6.56) pg/ml vs.(242.13 ± 7.86) pg/ml, P < 0.01].

CONCLUSIONOur results demonstrate that β3AA can improve cardiac function and reduce the serum levels of NT-proBNP in rat with heart failure.

OBJECTIVE：To investigate the effects of dexmedetomidine on regional cerebral oxygen saturation and cerebral function in patients undergoing intracranial aneurysm embolization. METHODS ：Totally 44 patients undergoing intracranial aneurysm embolization in the First Affiliated Hospital of Hunan University of TCM during Jun. 2017-Aug. 2019 were collected and randomly divided into group D （22 cases）and group C （22 cases）. Ten minutes before anesthesia induction ，group D was given intravenous injection of Dexmedetomidine hydrochloride injection 1 μg/kg；group C was given buffered normal saline 20 μL. Both groups were induced with Propofol emulsion injection+Midazolam injection+Fentanyl citrate injection+Cisatracurium besylate for injection. During the operation ，group D was given Dexmedetomidine hydrochloride injection 0.5 μg（/ kg·h）+Fentanyl citrate injection+Benzsulfosum atracurium for injection+Propofol emulsion injection to maintain anesthesia ；group C was continuously pumped with buffered normal saline 0.5 μg（/ kg·h）+Fentanyl citrate injection + Benzsulfosum aratracurium for injection Propofol emulsion injection to maintain anesthesia. Before anesthesia induction （T0）， immediately after anesthesia。induction （T1）， 1 min after tracheal intubation （T2）， immediately after operation finished （T3），immediately afte extubation（T4），the mean arterial pressure（MAP），heart rate 中国药房 2021年第32卷第7期 China Pharmacy 2021Vol. 32 No. 7 ·865· （HR），regional cerebral oxygen satur ation（rSO2）were observed in 2 groups. The levels of neuron specific enolase （NSE）and S100 β protein in serum were measured at T1，T3，6 h after operation （T6）. The recovery time ，intraoperative blood loss ， nitroglycerin amount and the occurrence of ADR were recorded. RESULTS ：MAP and HR of group D at T 2-T4 were significantly lower than those at T 0；MAP and HR of group C at T 2-T4 were significantly higher than those at T 0；the group D were significantly lower than the group C at the same period （P＜0.05）；there was no statistical significance in rSO 2 between 2 groups at T 0-T4（P＞ 0.05）. The levels of serum NSE and S 100β protein in 2 groups at T 3 were significantly higher than at T 1；those in 2 groups at T 6 were significantly lower than at T 3，but those of group D were significantly lower than the group C at T 3（P＜0.05）；there was no statistical significance in the levels of serum NSE or S 100β protein between 2 groups at T 1（P＞0.05）. The recovery time of anesthesia，the amount of nitroglycerin ，the incidence of tachycardia ，nausea and vomiting ，restlessness，shivering and cough in group D were significantly shorter or lower than group C （P＜0.05）；there was no statistical significance in the intraoperative blood loss between 2 groups（P＞0.05）. CONCLUSIONS ：Dexmedetomidine can maintain the hemodynamic stability of patients with intracranial aneurysm embolization during the perioperative period ，has little effect on rSO 2 and brain function ，and has good safety.
