Objective:To study the effect of insulin like growth factor 1 and insulin on the promoter activity of human ?1(Ⅰ) procollagen (COL1A1) gene and the influence of tumor necrosis factor ?(TNF?), interferon ? (IFN?) and interferon ?(IFN?) on the effect Methods:Two deletion constructs,pCOLH0 27 and pCOLH2 5 ,containing portions of 5' flanking region of the gene ( 268~+42 bp and 2 483~+42 bp respectively) ligated to the chloramphenicol acetyltransferase (CAT) reporter gene ,were transiently transfected into human skin fibroblasts The cells were subsequently treated with IGF 1 or insulin, and TNF? or IFN? or IFN? The CAT activity was assessed 24 h after the cytokines added Results:The results showed that 13 nmol/L IGF 1 caused 3 68 fold and 4 04 fold increase in the CAT activity of pCOLH0 27 and pCOLH2 5 respectively and that 2 5 ?mol/L insulin caused 3 69 fold and 3 93 fold increase in the activity of the two plasmids respectively TNF?,IFN? and IFN? reduced IGF 1 or insulin induced promoter activity of pCOLH2 5 Conclusion:IGF 1 and insulin could increase the promoter activity of the human (COL1A1) gene TNF?,IFN? and IFN? could suppress the promoter activity induced by IGF 1 and insulin

Shanghai Journal of Acupuncture and Moxibustion 2016;35(7):893-898
Objective To analyze the general situation of acupuncture-moxibustion in treating perimenopausal insomnia, as well as the treatment methods and acupoints selection.Method Domestic databases including China National Knowledge Infrastructure (CNKI), Wanfang, VIP, and database of China Biomedical Literature (CBM) were retrieved by using computer, and the literatures related to acupuncture-moxibustion in treating perimenopausal insomnia, published till December of 2014 were recruited. The general data, treatment methods, and acupoints selection of the eligible studies were statistically analyzed.Result Finally 85 studies were enrolled, of which, 76 were clinical trials with acupoints recorded; according to the frequency, the treatment methods were dry acupuncture-moxibustion methods (57.9%), comprehensive treatment of Chinese medicine (23.7%), and integrated method of Chinese and Western medicine (18.4%); the use of body acupuncture ranked the top (51.3%) among the acupuncture-moxibustion methods, followed by auricular point therapy (23.7%), moxibustion (9.2%), abdominal acupuncture (7.9%), and acupoint application (7.9%); the following acupoints ranked the top 10 among the used acupoints: Sanyinjiao (SP 6), Shenmen (HT 7), Baihui (GV 20), Shenshu (BL 23), Taichong (LR 3), Xinshu (BL 15), Taixi (KI 3), Neiguan (PC 6), Pishu (BL 20), and Zusanli (ST 36). The corresponding meridians in order were the Bladder Meridian, Spleen Meridian, Kidney Meridian, Governor Vessel, Liver Meridian, Heart Meridian, Stomach Meridian, Conception Vessel, Pericardium Meridian, Gallbladder Meridian, Large Intestine Meridian, and Triple Energizer Meridian; the used points were mostly distributed on lower limbs, then head and neck, back, upper limbs, and chest and abdomen.Conclusion Currently, the research in this field is focused on clinical prevention and treatment, while the theory and mechanism studies are comparatively less; based on the treatment principle of targeting the fundamental cause, it also presents the principle of selecting points according to meridians and regions in the treatment of perimenopausal insomnia with acupuncture-moxibustion.

The clinical practice in Pediatrics of Chinese medicine is the first step of the students to combine the theory with the clinical practice. The optimization teaching methods for clinical practice in Pediatrics of Chinese medicine was formed by using Delphi method of the extensive consultation from experts in colleges and universities of Pediatrics of Chinese medicine. We used this teaching method in students of Beijing University of Chinese medicine in 2011. Comprehensive evaluation to the implementation of effect was from assessment from students and analysis of exam results. The results showed that based on the survey of the students in the practice, the students in the experimental group give more positive evaluation than the control group on the necessity, satisfaction and harvest in the clinical practice in pediatrics of Chinese medicine.

Objective To investigate the relationship between positive experience and perceived social support of the parents with a cerebral palsy child. Methods 105 parents with a cerebral palsy child who were hospitalized in the Third Affiliated Hospital of Zhengzhou University between November , 2014 and January , 2015 were conveniently selected and investigated about their positive experience and perceived social support with general information questionnaire, positive aspects of caregiving and perceived social support scale. The correlation between the two was analyzed. Results The mean score of the parent′s positive experience was (30.82 ± 5.26); the dimension of self affirmation was (16.71 ± 3.06) and the dimension of life expectation was (14.10 ± 2.85). The scores of the parents′ positive experience were significantly different among gender, education of parents and the age,gender of children. The score of the parents′ positive experience was positively correlated with the total score of perceived social support (r = 0.214, P = 0.029) and the score of other support (r = 0.227, P = 0.020). Conclusions The parents′ positive experience was medium of the high level, which is worth of more attention in order to improve it. The higher perceived social support score is , the more positive experience parents will have.

Objective To explore the inhibitory effect of pulsed ultrasound on skeletal muscle fibrosis after injury.Methods Thirty elderly male rats with gastrocnemius muscle injury were divided into an ultrasound group (UG) and a control group (CG) using a random number table.The injured muscles in the UG were treated using pulsed ultrasound (frequency 1 MHz,average strength 40 mW/cm2,duty cycle 20%) for 10 min daily from day 3 after the injury.The CG was given no treatment.On days 3,7,14,21 and 28 after the injury,histological and immunohistochemical analyses of the gastrocnemius muscles of both groups were performed.Results The collagen fiber mean optical density of the muscles increased gradually after the injury and reached its peak on day 21.It was significantly lower in the UG than in the CG on each test day.The expression of α-SMA increased gradually after the injury,but it too remained significantly lower in UG than that in CG.Conclusion Pulsed ultrasound may reduce collagen formation and α-SMA expression in injured skeletal muscle,and then inhibit muscle fibrosis.

AIM: The purpose of the present study was to detect intracellular Ca 2+ changes in living brain slices during focal cerebral ischemia/reperfusion (I/R) and reveal the role of intracellular Ca 2+ in the cerebral I/R injury. METHODS: The model of focal cerebral I/R was established in rats by reversible inserting a nylon thread, and dynamic change of intracellular Ca 2+ in brain slices was determined using laser confocal imaging system. RESULTS: ① Ca 2+ gradually enhanced with increase in ischemic time in cortex and striatum. ②At 1 h ischemia/ 10 min reperfusion, Ca 2+ increased significantly in striatum, but Ca 2+ decreased at 3 h reperfusion compared with 10 min reperfusion. ③ Ca 2+ markedly enhanced at 6 h ischemia compared with 1 h ischemia, and after 3 h reperfusion Ca 2+ decreased, but was still higher than that in sham-operation group. ④The striatum is more sensitive than cortex to ischemia/reperfusion. CONCLUSION: Ca 2+ overload in the area of cortex and striatum may play an important role in cerebral ischemia/reperfusion injury in rats.
