Stem cell therapy provides immense hope for restoring the impaired cardiomyocytes .However, it has been debated on the effectiveness , mechanisms , and survival of the donated cell population in the ischemic myocardial milieu .Protective paracrine effect of stem cells on cardiomyocytes gradually arose great attentions .Exosomes , as typical representative of paracrine effect of stem cells, are 30-100 nm in size and tiny microvesicles released by cells in response to different physiological states , and enriched in pro-teins, messenger RNAs, and miRs characteristic of parental stem cells , represent great potential for treating cardiovascular diseases . Recent studies show that exosomes from different kinds of stem cells can effectively promote cardiac function by means of promoting the donated cell survival , proliferation and angiogenesis in the ischemia heart .The aim of this review is to summarize current research ef-forts on exosomes from different kinds of stem cells , including their potential mechanism to develop a potentially viable therapy for the treatment of impaired cardiomyocytes via promoting cardiomyocytes survival , proliferation and angiogenesis;inhibiting inflammatory re-sponse and cardiac fibrosis after myocardial infarction .

Objective To identify whether soybean isoflavones plays a role in the prevention of chronicallograft nephropathy(CAN)in rats.Methods Forty-five male Lewis rats as receptors were randomly divided into 3 groups,receiving a diet with protein from high isoflavone soy protein fraction (HIS),low isoflavone soy protein fraction(LIS)or casein(CAS)starting one week before renal transplants from fisher donors,and continuing throughout the study.Serial serum and urine samples were collected at the beginning of the study,and at 4th,12th and 24th week.All rats were killed and the grafts were harvested in the 24th week.The functional and histopathogical changes of renal grafts were evaluated.Results In HIS group,arteria caudilis systolic blood pressure(SBP)value,24 h uri- nary protein(Upro)and serum creatitine(Cr)concentrations were significantly lower than those in LIS and CAS groups(all P

Objective To evaluate the effect of laparoscopic myomectomy. Methods Clinical data of 62 cases of laparoscopic myomectomy were analyzed retrospectively. Results Success was achieved in all the operations.Of the 62 cases,intramural myoma was confirmed in 45 cases,and subserous myoma,17 cases (non-pedicled,10 cases; pedicled,7 cases).A total of 101 myomas were removed,with a diameter of 1～9 cm (mean,6 8 cm).The mean operative time was 25～270 min (mean,99 min),and the intraoperative blood loss,10～400 ml (mean,63 ml).The postoperative hospital stay was 2～8 days (mean,4 7 days) and the overall complication rate was 25 8% (16/62).Follow-up observation in 42 cases for 2～36 months (mean,9 months) found recurrence in 2 cases and full-term pregnancy in 2 out of 10 cases with infertility. Conclusions Laparoscopic myomectomy has advantages of safety,quick recovery,short hospital stay and fewer complications.

Objective To analyze the present situation about early screening of developmental dysplasia of the hip( DDH) of infants in Shapingba district of Chongqing,and to explore the methods to improve the rate of diagnosis about DDH. Methods A total of 2 066 infants among 0~6 months old living in Shapingba district of Chongqing,were examined with clinical and ultrasound method on hip. Results Six infants with DDH were discovered among the 2 066 infants,which was more common in the female baby. The deficiency of hospital in which can exam hip with ultrasound method and the deficiency about DDH were the significant factors affecting the low detection rate. Conclusion Necessary measure must be taken to improve the low detection rate of DDH.

Muscle recently has been identified as a good source of adult stem cells that can differentiate into cells of different lineages.Researchers have identified two types of stem cells in skeletal muscle.Further research is necessary to delineate the relationship between different populations of musclederived stem cells(MDSCs)and between MDSCs and other adult stem cells.The methods used to isolate these cells appear to influence the stem cell characteristics.As these efforts continue,the potential for MDSCsbased therapy for other musculoskeletal injuries,as well as for cardiac and smooth muscle injuries,is currently being explored.The behavior,biocharacteristic,isolation,differentiation and the probability of application to regenerate lost or diseased tissue of MDSCs were summarized.

ObjectiveTo observe the effect of digital auditory activation and touching intervention on infants with cerebral dysfunction.Methods388 infants with perinatal high-risk factors and abnormal result of Denver Development Screening Test (DDST) were randomly divided into group A (n=135), group B (n=128) and group C (n=125), and treated with digital auditory activation combined with touching (group A), simple touching (group B) and simple drug (group C) with 10 days as a course. All infants were tested with DDST after one therapeutic course, and tested again with DDST after the infants of group B and group C treated continuously for six therapeutic courses; and all infants were assessed with the Gesell development quotient (DQ) after six months.ResultsAfter one therapeutic course, normal rate of DDST was 71.11% in group A, 26.69% in group B and 20.00% in group C. After six therapeutic courses, that was 90.37 % in group A, 62.50 in group B and 40.00% in group C. After six months, the children with the Gesell DQ over 86 scores was 125 (92.60%) in group A, 90 (70.31%) in group B and 62 (49.60%) in group C. There were significant differences among three groups ( P<0.01).ConclusionThe digital auditory activation combined with touching has short therapeutic course and high efficacy, so it is a good therapeutic method for infants with cerebral dysfunction.

Insomnia has become a threat to public health, and acupuncture has shown an advantage in treatment of insomnia with good efficacy and few side effects.

Bi Qiu in TCM is the equivalent of allergic rhinitis in Western Medicine, its incidence has a close relationship with six exogenous. Many physicians treat this disease from the pathogenic wind and cold, relatively considering about pathogenic heat. This article reviewed and researched literature about ancient physicians’ diagnosis and treatment of allergic rhinitis from the aspects of etiology, pathogenesis, and treatment of allergic rhinitis, with a purpose to provide certain evidence and reference for modern clinical prevention and treatment of allergic rhinitis.
