Musashil is an evolutionarily conserved RNA binding protein. It plays an important role in the aspects of maintaining stem cell state, differentiation and tumorigenesis. Notch signal pathway plays an important role in the proliferation of neural stem cells after cerebral ischemia. This article briefly introduces the structure and molecular characteristics of Musashil and Notch, and reviews the interaction in the neurogenesis of Musashil and Notch signaling pathway after cerebral ischemic reperfusion.

Neuronal apoptosis is one of the important forms of neuronal death in ischemic stroke.N-methyl-D-aspartate (NMDA) receptor-mediated excitatory amino acid toxicity plays an important role in neuronal apoptosis. It is the initiator and executor of apoptosis in neuronal cells. NR2B is the major regulatory subunit of this receptor, its transmembrane segment M2 is a reflexed membrane loop region facing cytoplast toward intramembrane, forming the inner wall of ion channel, which determines the permeability of the NMDA receptor ion channel to calcium. Glutamate mediates cell injury mainly through calcium overload, therefore, NR2B subunit plays a vital role in the neuronal apoptosis in ischemic stroke.

Autosomal dominant polycystic kidney disease(ADPKD),a common inherited disease,is characterized by massive enlargement of fluid-filled renal cysts.Progressively enlarging cysts compromise normal renal parenchyma,reduce renal function and lead to renal failure.Up to now,the treatment options for ADPKD have been limited to renal replacement therapy by dialysis or by transplantation for patients with end-stage renal failure.Inhibition of cyst fluid secretion,suppression of cyst epithelial cell growth and prevention of renal failure are new approaches to treat PKD.

patients with chronic alcoholic polyneuropathy (CAPN ) were described. They were all male with age rainging from 33 to 70 years (mean age 53. 7). The cardinal symptoms are. pain and numbness in the extremities, stocking and glove decreased of pain and temperature sense in the legs and arms, the loss of vibration sense and muscule atrophy. The motion nerve conducting velocity (MCV) and sensory nerve conduction velocity (SCV) all are slowed in varying degrees. Superficial peroneal nerve biopsy identified myelin degeneration of myelinated nerve fibers, axonal degeneration or disappearance, degeneration of Schwann cell and also involved perineurium. The change was due to avitaminosis for long-term drinking.

Objective To observe the effects of recombinant plasmid of rat's interstitial collagenase on experimental liver fibrosis. Methods We constructed the recombinant plasmid of rat's interstitial collagenase fused Flag peptide which can be expressed in eucaryotic cells. After bound to galactose terminal glyco poly L lysine(G PLL), we transferred the recombinant plasmid to the rat's fibrotic liver in vivo by intravenous injection, then observed the effects of the plasmid on the fibrotic liver by RT PCR, immunohistochemistry and the observation of pathology. Results The recombinant plasmid of interstitial collagenase could be expressed in rat liver, the expression of the plasmid could increase the degradation of type Ⅰ and type Ⅲ collagen in the rat's fibrotic liver compared with fibrotic modal group ( P 0.05). Conclusion The recombinant plasmid of interstitial collagenase have some effects on liver fibrosis, but this effects is limited.

Objective To observe the clinical effect of early diabetic nephrosis treated with Danhong injection and Losar- tan Potassium Tablets.Methods 60 patients were randomly divided into treatment group (n=30) and control group (n=30).Both grougs take orally medicine or insulin for normal blood sugar,the control group were treated with con- ventional treatment.On the basis of conventional treatment,the treatment group were treated with Danhong injection and Losartan Potassium.Results After treated for 28 days,the UAER,BUN,SCr and hemorheology were significantly improved in the treatment group than in the control group (P

Objective To certify the linear range of WBC measured by CD3700.Methods Use the white stratum of blood after centrifugation.Then,the high value specimens were diluted with saline to get a series of samples with different concentrations.Every specimen was measured twice in order to keep the sequence of specimens randomly.The perform outlier test,polynomial regression analysis,and the random error estimation were carried out.Results There was no outlier in the results.It was demonstrated by polynomial regression to be linear from(0～219)?109 L-1.The random error was within the allowable limit of 1/4CLIA'88(3.75%).Conclusion The linear range of WBC measured by CD3700 is just like that of the manufacturer claims.

OBJECTIVETo observe the immediate antihypertensive effect of guasha combined with bleeding therapy for mild (grade I) hypertension.

METHODSThirty patients with mild (grade I) hypertension and 30 cases with normal blood pressure were compared. Areas and acupoints in governor vessel, meridian of foot-taiyang, meridian of hand-yangming and meridian of foot-yangming were scraped for 3 times, which was followed by bleeding therapy. The blood pressures after each guasha and bleeding therapy were recorded as well as the skin temperature in Dazhui (GV 14) after each guasha. The treatment was given once a week and totally 4 treatments were given.

RESULTSThere were significant antihypertensive effects after the first guasha, the second guasha and the third guasha and bleeding therapy (all P<0.01), in which guasha combined with bleeding therapy had the most significant antihypertensive effect (P<0.01). The skin temperature in Dazhui (GV 14) was obviously increased after three times of guasha (all P<0.01).

CONCLUSIONGuasha or combined with bleeding therapy has better antihypertensive effect for mild hypertension, which is likely to be related with warming stimulation on meridians and acupoints.

The efectienes of acpuncture for smoking cessation was systematically evaluated in this paper. By using computer retrieval in Chinese national knowledge infrastructure (CNKI), WANFANG database, VIP database, PubMed, ScienceDirect and Springer, the randomized controlled trials (RCTs) regarding acupuncture for smoking cessation from January of 1983 to December of 2013 were collected; by using Table of Standardized Report Factors for Acupuncture RCTs, each inclusive RCT was evaluated; and by using RevMan 5. 2 software, the Meta-analysis was performed. Totally 24 RCTs were included, involving 3084 cases of smoking. The result of literature quality assessment showed that the average score was 25. 71 points without low-quality RCT which had a score of less than 16 points. The Meta-analysis showed that acupuncture could significantly increase the short-time abstinence rate [RR=1. 48, 95% CI (1. 18,1. 84), Z=3. 47, P<0. 0005] and number of cigarettes smoked daily [RR=4. 35, 95% CI (2. 03, 6. 66), Z=3. 68, P<0. 001] and FTND [RR=2. 37, 95% CI (1. 88, 2. 86), Z= 9. 44, P<0. 00001], however, it could not increase the long-time abstinence rate [RR=1. 40, 95% Cl (0. 90, 2.17), Z=1. 49, P>0. 05]. Compared with other treatment, acupuncture has positive advantages on short-time abstinence rate, however, its effect on long-time abstinence rate needs to be verified by high-quality, large-sample and multi-center RCT in the future.

Objective To research the expression of the estrogen receptor alpha ( Erα) and estrogen receptor beta ( Erβ) in uvea tissues of the female rats, and to provide molecular biology data for further studies of the relation estrogen to uvea diseases. Methods Twenty-two adolescent SD female rats were selected. All rats were killed by dislocation of cervical vertebra, the eyeballs were in paraffin imbedding and made to a series of sections, using immunohistochemical method;Erα and Erβ distribution were investigated in uvea tissue of rats;and quantitied by Tanaka scores analytical method. The uteri of rats was used as positive control and PBS as negative control. The level of estradiol in serum of the rats were examined by radioimmunoassay. Results The expression level of Erβ was moderate or highter in stroma cell, anterior pigment epithelium as well as pasterior pigment epithelium of the iris, unpigmented epithelium, pigmented ciliary epithelium and vascular endocemet of the choroid layers. But Erα was not obviously expressed in uvea tissues. The expression rate of Erβ was higher than Erα in these tissues(P＜0.05). Immnoreactivity positive substance was granule, which was distributed in the cytoplasm or in the nucleus. The level of estradiol in serum of the rats was (22.13±3.54)ng/L.Conclusion The expression of either Erα or Erβ in uvea tissues of rats is mainly in Erβ. The results indicate that uvea tissue is regulated directly by estrogen throught Erβ.
