AIM: To study the efficacy and adverse reactions of carnitine on patients with acute cerebral infarction.　METHODS: One hundred and thirty-five patients with acute cerebral infarction diagnosed by CT or MRI were randomly divided into 2 groups, on the basis of conventional therapy. Sixty-eight patients in carnitine group (M37,F31; age 60 a± s 17 a) received carnitine 2-3g, iv, drip, qd for 28 d. The other 67 patients of control group (M39, F28; age 63 a±17 a) received compound salvia miltirrhiza 20 mL in dextran-40 glucose injection 500 mL, iv, drip, qd for 28 d.　RESULTS: The total effective rates of carnitine group and control group for acute cerebral infarction were 80％ and 55％, respectively (P<0.05). No adverse reactions were found.　CONCLUSION: Carnitine is safe and effective in the treatment of acute cerebral infarction.

Objective To observe the curative effect of captopril and metoprolol in the treatment of chronic Keshan disease (CKD). Methods One hundred and ninty-five patients with CKD chosen from Juxian, Wulian, Yishui, Pingyi, Sishui and Zoucheng in Shandong Province were randomly assigned to control group, captopril group and metoprolol group according to NYHA cardiac functional grading. All cases were given diuretics, digitalis and vasodilating agents as routine treatment. On this basis, captopril and metoprolol was administered in captopril group and metoprolol group respectively. After 12 months of follow-up visit, the causes of cardiac death, hospitalization status and the changes of heart size, electrocardiogram, blood pressure and heart rate were all observed. Results It was found that the mortality of captopril group and metoprolo] group was 4.76% (3/63), 5.00% (3/60) respectively, both lower than the control group 10.61%(7/66). But this difference had no statistically significance(P=0.39). Besides, the hospitalization days of each year in captopril group and metoprolol group was respectively (19.12± 20.35) and(18.86±21.52)days, much more reduced than in the control group[(21.45±21.74)days, q=3.17, 3.38, P<0.05]. The detection rate of cardiothoracic ratio decreased in captopril group and metoprolol group [45% (27/60) and 40.4% (23/57)] After treatment showed more pronounced amelioration than the control group [18.6% (11/59), χ2=9.51,6.59, all P<0.0125], still the detection rate of cardiomegaly and invariability had no significant difference among three groups (χ2=2.50,4.75, all P>0.05). The elimination coefficient of ectopic rhythm in metoprolol group [56.5% (13/23)] was pronounced higher than the control group and captopril group [23.8% (5/21), 22.7% (5/22)], but differences had no statistically significance(P=0.0358,0.0331, all P>0.0125). Significant differences were found in systolic blood pressure(SBP), diastolic blood pressure(DBP) and heart rate(HR) in three groups prior and post-treatment(F=47.51,44.23,80.66, all P<0.01). The interaction of therapy and treatment time had influence on SBP and HR (F=3.19,37.44, all P<0.05), but had no influence on DBP(F=2.21, P> 0.05). There was no difference in SBP, DBP or HR among three groups before treatment(F=0.28,0.57,1.80, all P>0.05). After treatment, SBP and DBP in captopril group, metoprolol group and the control group[(109.0±10.9), (112.2±12.8), (114.7±13.2)mm Hg, (69.3±7.2), (72.1±9.5), (73.3±9.3)mm Hg] were all lowered compared with pre-treatment[ (117.1±13.4), (119.0±14.4), (117.6±14.1)mm Hg and (74.2±10.2), (76.3±10.8), (75.4±11.1)mm Hg, t=4.79,4.47,2.08,5.12, 4.32,2.15, all P<0.05]. HR was reduced in metoprolol group, being [(66.2±7.7), (75.9±11.5)times/min] before and after treatment(t=10.81, P<0.01), while it remained unchanged in captopril group and control group[(70.6±8.0), (72.6±10.5) times/min and (71.9±10.4), (73.8± 12.2)times/min, t=1.77,1.74, all P>0.05]. After treatment, both SBP and DBP of captopril group were significantly lower than that in the control group (q=3.52,3.56, all P<0.05); HR was reduced in metoprolol group, lower than that in captopril group and control group(q=5.44,3.73, all P<0.01). Conclusions Having a tendency of depressing mortality, captopril and metoprolol can reverse or delay myocardial remodeling and reduce admission rate in a safe,reliable and economic way, and are worth to be widely used in the treatment of chronic Keshan disease.

As a novel transdermal drug delivery technology of minimally invasive, safe and efficient, microneedles have received increasing attention. The microchannels formation by microneedles onto the skin is a prerequisite and key for microneedles to deliver drugs. However, there is still a lack of systematic evaluation in skin microchannels. This review summarized influencing factors and evaluation methods in microchannels formation and healing by microneedles, including geometric parameters, materials for preparation, drugs, penetration parameters, differences among the skin of subjects, and presence or absence of occlusion. This review provides reference for other scholars to further study the effectiveness and security of microneedle applications.

Objective To investigate the therapeutic action of Taurine in patients with cerebral infarction(CI)induced by hyperhomocysteinemia(Hhcy).Methods The 100 CI patients induced by Hhcy were randomly divided to two therapy groups.One group was administered Taurine,the other group was administered Folacin combined with Vitamine B12 for 8 weeks.Before and after treating,the serum levels of homocysteic acid(Hcy),Folacin and Vitamine B12 were detected,NIHSS and BI were evaluated.Results The serum levels of Hcy were significantly decreased after administering in both two groups(all P

Objective To explore the role of serum S-100B concentration of umbilical cord blood and blood on the 24 h after admission in the early diagnosis and development of newborn hypoxic-ischemic encephalopathy(HIE).Methods Forty-six HIE newborns(31 cases with mild HIE and 15 cases with moderate and severe HIE)were selected as HIE group,and 43 normal full-term newborns were selected as control group.The umbilical cord blood sample and blood sample were aquired on the 24 h after admission.The serum S-100B concentration was detected by enzyme-linked immunosorbent assay(ELISA)analysis.Results 1.There was no significant difference of serum S-100B concentration between the male sub-group and female sub-group of normal group and their birth weight had no significant relative to the serum S-100B concentration.2.The serum S-100B concentration of umbilical cord blood of control group and HIE group were(1.03?0.32)and(2.53?1.1)?g/L,respectively,there was significant difference between two groups(t'=8.848 P

OBJECTIVETo study the dynamic changes in the protein marker expression in the spermatogonial stem cells (SSCs) of mice at different ages by iTRAQ protein mass spectrometry and to screen new markers using the bioinformatic proteome database.

METHODSBased on the postnatal weeks, we divided 80 healthy male C57BL/6 mice into eight age groups of equal number, harvested their testicular tissues, extracted proteins following purification of the SSCs by compound enzyme digestion and magnetic-activated cell sorting. Then we analyzed and identified proteins using two-dimensional electrophoresis, protein mass spectrometry, and protein database information.

RESULTSTotally, 248,510 mass spectra were obtained from the MS experiment and 1132 proteins were identified. By the criteria of >1.2-fold for protein abundance difference and P value <0.05, we identified 298 differentially expressed proteins and 9 currently known makers of SSCs (PCNA, GFRalpha1, CDH1, Annexin A7, UCHL1, VASA, CD49f, CD29, and PLZf). Compara- tive analysis showed different expressions of the proteins in the SSCs of the mice of different ages, and the differences in the expressions of GFRalpha1, CD49f, and CD29 were consistent with the findings in other published literature. Ten proteins (P63, CD71, CD98, K19, ACE, K18, K15, K17, SH2, and SH3) were selected as SSC markers to be further studied.

CONCLUSIONThe proteins in SSCs are differentially expressed in mice of different ages. The technology of iTRAQ protein mass spectrometry can be used to analyze and compare the proteome information of mouse SSCs, obtain differentially expressed proteins in mice of different ages, and thus offers a new ap- proach to further analysis and study of the function and roles of these differential proteins.
