Through searching domestic and foreign medical journals in CNKI, Wanfang database, VIP database and Pubmed database from January of 2003 to November of 2013, 39 articles regarding musical electroacupuncture (MEA) were analyzed. The result showed that MEA was clinically used to treat neurological and psychotic disorders; because it was combined with musical therapy and overcame the acupuncture tolerability, and MEA was superior to traditional electroacupuncture. However, problems such as low research efficiency and the mechanism of MEA superiority and the musical specificity not being revealed by research design still exist. In future, large-sample multi-center RCT researches should be performed to clarify MEA clinical efficacy. With modern science and technology and optimized study design, guided by five-element theory of TCM, researches on different musical elements and characteristics of musical pulse current as well as MEA's correlation with meridians and organs should be studied, so as to make a further exploration on MEA mechanisms and broaden the range of its clinical application.

Objective To study the effect of injured podocytes on glomerular maturation and its underlying mechanism in neonatal mice.Methods Single i.p.injection with puromycin aminonucleoside (PA,0.1 mg/g BW) was given to ICR neonatal mice at day 1 after birth (1 dpp). Littermates injected with normal saline (NS) were used as control.Animals were examined for urine protein,blood pressure,kidney weight/body weight (KW/BW),renal histology at 2,4,8,12, 30,60 and 90 dpp (n=6～9 for each group).Immunohistochemistry and quantitative RT-PCR were performed to examine the expression of WT-1,CD31,VEGF,Flk-1,Ang-1,Ang-2,Tie-1 and Tie-2.Results Mice with PA injection had lower kidney weight and body weight at all time points as well as lower KW/BW at 4,8,12 dpp when compared with NS controls.Electron microscopy revealed nearly complete foot process effacement and segmental microvillous transformation as early as 1 day after PA injection.PA-injected kidneys showed fewer capillary loops and decreased maturation index as well as less CD31-positive endothelium in cortical glomeruli at 12 dpp. Glomerular mesangial injury and developing glomerulosclerosis along with proteinuria were noted in PA-injected kidneys starting from 30 dpp.Significantly increased systolic blood pressure was detected at 60 dpp in PA mice.Compared with NS injection,PA injection significantly induced decreased mRNA expression of Flk-1 and Tie-2 as well as increased expression of Ang-1,without obvious changes of VEGF at 2 dpp.Conclusions Podocytes in neonatal kidney of ICR mice are susceptible to PA. Such podocyte injury can alter the expression of VEGF and angiopoietin system in glomeruli,leading to abnormal development of glomerular capillaries,and subsequent proteinuria,hypertension and glomerulosclerosis.

Objective To examine the effect of eating behavior and dietary intake on the sleep quality of college students,and to provide basis for improving students' sleep quality.Methods College students from Hangzhou Normal University were randomly selected and they were investigated from October to November,2014.Pittsburgh Sleep Quality Index (PSQI) was used to measure the quality of sleep,and a self-designed questionnaire was used to measure eating behavior and dietary intake.Results A total of 588 college students were investigated.The average score of PSQI was 4.72 ±2.52,and 76 (12.9％) of the respondents have poor sleep quality.Single-factor analyses showed that sleep quality was not associated with gender,BMI,cigarette smoking and academic pressure,but was associated with peer effect,meal regularity,and frequency of fish and poultry intake (P ＜ 0.05).Multi-factor logistic regression showed that frequency of eating-out (OR =3.04,95％ CI:1.58-5.84;P =0.001,4 or more than 4 times vs.less than once per week) irregular dinner (OR =1.96,95％ CI:1.23-3.40;P =0.017,irregular vs.regular) and less fish intake (OR =2.48,95％ CI:1.27-4.85;P =0.01,less than once vs.2-3 times per week) increased the risk of poor sleep quality.Conclusion Eating behavior and dietary intake are closely related to sleep quality of college students and they should concern about meal regularity and nutrition balance.

OBJECTIVETaking Chinese compound medicine Yuchangning as a research model, prepared the pH and time dependent Yuchangning tablets for colon-specific delivery (PT-YT-CSD), and evaluated the releasing property in vitro.

METHODThe coating prescription is filtered by the release extent of matrine and oxymatrine in vitro and the wicking rate of the tablet, which including the category and proportion of film forming agent and porogen, the sort and dosage of fluidizing agent, the increment of weight after coating and so on. The releasing property of the preparation is evaluated by the dissolution tests in vitro through measuring the content of matrine and oxymatrine content.

RESULTThe preparation method of the PYTCSD: After prepared plain tablets, the 95% alcoholic solution of EC and Eudragit II are mixed in a 7:3 EC: Eudragit II ratio and then added in DEP up to 10% of the coating amount, reduced the alcohol concentration to 4% by diluting with ethonal. Tablet was coated by the alcohol solution and the weight of the plain tablet was increased by 3%. The dissolution tests in vitro indicated that matrine and oxymatrine were not dissolved in the simulated gastric juice after 2 h. The accumulative quantities of matrine and oxymatrine were less than 10% in the simulated intestinal juice after 4 h. The quantities of matrine and oxymatrine are 75.7% and 76.8% in the simulated colon juice after 1 h.

CONCLUSIONThe PYTCSD was prepared and the preparation could fulfil the aim of delivering in the specific colon in vitro.

ObjectiveTo evaluate the neurobiological characteristics of human histio-amniotic mesenchymal (hAMCs) and effect of hAMCs transplantation into the brain to treat Parkinson's disease(PD) modle mice.MethodsThe expressions of mesenchymal stem cells, neural stem cells, dopaminergic neurons and markers related to neurogenesis such as Vimentin, STRO-1, nestin, CD133, β-tubulin, TH, DAT, Ngn2 and mash-1 in hAMCs were evaluated through immunocytochemical stain; and the mRNA transcriptions of neural stem cell markers, Vimentin and nestin in hAMCs were detected by RT-PCR. The PD model was induced by MPTP(i.p.) in C57BL/6 mice transplanted with hAMCs into the right striatum. The therapeutical effect of hAMCs on PD mice was evaluated by spontaneous movement, rotating bar test and the immunohistochemistry of anti-human chondrosome and TH antibodies in striatum.ResultshAMCs induced by nerve cells culture medium, expressed mesenchymal stem cells, neural stem cells, dopaminergic neurons and other specific markers related to neurogenesis mentioned above. The frequency of spontaneous movement in PD mice was significantly increased(P<0-05), and the time of rotating bar was obviously prolonged(P<0-05) after transplantation with hAMCs.ConclusionhAMCs possess the characteristics of nerve cells after cultured in vitro and can significantly recover the damage of motor function induced by MPTP after transplantation into striatum in PD model mice.

OBJECTIVETo investigate the prevalence of viral infections and putative association of viral infection with illness severity in young children with severe lower respiratory tract infection (LRTI) in Chongqing.

METHODRespiratory secretion specimens were collected from 119 hospitalized patients with severe pneumonia from December 2006 to March 2008.After being processed, the samples were detected for respiratory viruses including respiratory syncytial virus (RSV), adenovirus (ADV), human metapneumovirus (hMPV), human bocavirus (HBoV), parainfluenza virus 1, 2, 3 (PIV 1, 2, 3), influenza virus A and B (IVA and IVB) either by PCR or RT-PCR. Clinical data were analyzed along with virological data by using appropriate statistical methods.

RESULTViral pathogens were identified in specimens of 86 (72.3%) cases, among which RSV was detected in 49 (41.2%) patients. More than one virus was detected in 23 individual (26.7%) samples, of which 19 were dual positive for RSV and another virus. Bacterial cultures were performed for 69 patients. Both bacterial and viral pathogens were identified in 53 (76.8%) patients. Bacterial and viral coinfection was demonstrated in samples from 41 (59.4%) cases.

CONCLUSIONViral pathogens are the main etiology of severe pneumonia in young children in Chongqing area during the study period. RSV was the most frequent viral pathogens, followed by ADV and hMPV. Coinfection with respiratory common viruses was relatively common, though co-infection with viruses did not appear to aggravate the patients' condition.

Biomacromolecules play an important role in the treatment of many diseases, but as a result of cell membrane serving as the natural barriers, only the small molecular compounds whose molecular weights are smaller than 600 Da can get through cell membrane and enter the cell. In recent years, some short peptides (the length less than 30 amino acids) are found to have the cell-penetrating function, called cell-penetrating peptides (CPPs). They are able to effectively translocate segments of protein, polypeptides, nucleic acid into the cells of many mammal animals with many methods. They have high transduction efficiency and will not lead to cell damage. So, the discovery of CPPs has a very good applicable prospect in such research fields as cell-biology, gene-therapy, drug transduction in vivo, evaluation of clinical medicine and medical immunology. This paper reviews the types and characteristics of CPPs, internalization mechanisms, applications, and their existing problems.
