Pulmonary hypertension ( PH) is occult, with no distinctive clinical manifestations and poor prognosis.Pulmonary vascular remodelling is an important pathological feature in which pulmonary artery smooth muscle cell ( PASMCs) pheno- typic switching plays a crucial role.MicroRNA (miRNA) is a class of evolutionary highly conserved single-stranded small non-coding RNA.Recently, an increasing number of scholars have found that miRNA can play an important role in the occurrence and development of PH by regulating the phenotypic switching of PASMCs, which is expected to be a potential target for the prevention and treatment of PH.It has been found that miR NA such as miR-221 , miR-24, miR-15b, miR-96, miR-23a.miR-9, miR-214, miR-20a can promote the phenotypic switching of PASMCs, while miRNA such as miR-21, miR-132, miR-182, miR-449, miR-206 .miR-124, miR-30c, miR-140.miR-17-92 cluster can inhibit it.This article aims to review the research progress on miRNA that mediates PASMCs phenotypic switching in PH from both growth factor-related miRNA and hy- poxia-related miRNA.

Objective To evaluate the efficacy of sleep-regulating technique of low resistance thought imprint psychotherapy (TIP3-2) for insomnia. Methods A total of 120 patients with insomnia were enrolled and randomly allocated to either a treatment group (60 patients) or a control group (30 patients). The patients in the treatment group and the control group were treated by TIP3-2 and zopiclone for 4 weeks, respectively. The therapeutic effect was evaluated using the Pittsburgh Sleep Quality Index (PSQI), polysomnography and the self-made sleep confidence scale. Results A total of 79 patients in the treatment group and 28 patients in the control group completed treatment. PSQI scores showed that overall sleep quality (1.3 ± 0.65 vs. 1.8 ± 0.50;t=6.378, P=0.000), daytime function (1.5 ± 0.89 vs. 2.1 ± 0.66;t=13.624, P=0.000) and total score (9.6 ± 3.35 vs. 12.4 ± 2.83;t=22.124, P=0.000) in the treatment group were significantly improved compared with the control group. Polysomnography showed significant difference between two groups in the times of awakening (3.4 ± 2.49 vs. 4.2 ± 4.02;t=4.196, P=0.043), and the percentages of sleep stages 1 and 2 (stage 1:35.0%± 19.42%vs. 43.0%± 23.31%, t=4.593, P=0.034;stage 2:40.3%± 16.47%vs. 34.9%± 16.57%, t=4.255, P=0.042). The total score of the sleep confidence scale in the treatment group showed a significantly improvement compared with the control group (8.6 ± 5.85 vs. 12.8 ± 3.84, t=11.346, P=0.001). Conclusion TIP3-2 can improve sleep confidence, have certain efficacy for insomnia, and may be superior to zopiclone.

Objective To study the mechanisms of Chinese medicine Euphorbia kansui induced liver damage. Methods 40 mices were selected and radomly divided into four groups according to the dose of Chinese medicine Euphorbia kansui used,there were 4 g/kg group(1/8 LD50 ),2 g/kg group(1/16 LD50),1 g/kg group(1/32 LD)50,and control group,which were given saline. After continuous administration for 21 d by ig,the body weight and liver coefficient of mice in all groups were determined,liver histological changes were detected by HE staining. The serum enzymatic activity of alanine aminotransferase (ALT)and aspartate aminotransferase (AST),the levels of superoxide dismutase (SOD)and glutathione peroxidase (GSH-Px),the content of malondialdehyde (MDA),superoxide anion radical (O2-·)and hydroxyl radical (OH·)were all measured by ultraviolet spectrophotometry. The changes of reactive oxygen species (ROS)content were detected by flow cytometry. Results With the increase dose of Chinese medicine Euphorbia kansui,the body weight of rats were decreased,and liver coefficient were increased(P<0.05). The serum ALT,AST activity were significantly increased,SOD and GSH-Px activity were significantly decreased(P<0.05),MDA content were increased significantly,radical O2-·, OH·and intracellular ROS levels were all increased (P<0.05 ). Conclusion Chinese medicine Euphorbia kansui induced liver injury though lipid peroxidation.

Objective To evaluate the efficacy of sleep regulation technique of thought imprint psychotherapy in lower resistant state (TIP) for the treatment of primary insomnia.Methods 45 hospitalized outpatients with primary insomnia from sleep medical clinic of Guang'anmen Hospital were randomized at a 2 ∶ 1 ratio into a therapy group and a control group using random table.In the therapy group,patients received sleep regudation technique of TIP twice per week.In the control group,patients were asked to take zopiclone 3.75mg per night 30 minutes before bedtime.And the maximum dose can be 7.5mg according to their condition.The treatment lasted one month.Pittsburgh sleep quality index (PSQI) was used to assess sleep quality.Results ① After 4 weeks treatment,the clinical efficacy showed significant difference between the two groups (therapy group was 80％,control group was 33.3％).② Inner group comparison:therapy group was significantly improved in PSQI sleep quality (1.20 ± 0.71),sleep latency(1.53 ±1.01),sleep time(1.23 ±0.82),sleep efficiency(0.90±1.21),sleep disorders (1.30±0.65),sleep medication(0.13±1.36),daytime function (1.67±0.99),total score(8.30±3.19),(P＜0.05); the control group was significantly improved in the PSQI sleep quality(1.60±0.91),sleep latency(1.87±0.64),(P＜0.05).③ Inter group comparison:after treatment,compared to the control group,the therapy group was superior in the sleep latency,sleep time,sleep efficiency,sleep medication,daytime function,and total score ofPSQI (P＜0.05).Conclusion Sleep regulation techmique of thought imprint psychotherapy in lower resistant state can improve sleep quality of primary insomniacs.
