OBJECTIVE:To systematically review the related evidence-based guidelines of purulent meningitis in children,and to provide evidence-based reference for clinical treatment. METHODS:Retrieved from PubMed,EMBase,CBM,Wanfang Data-base,CJFD and VIP,NGC,GIN,TRIP and websites of domestic and international medical associations and industry bodies,the treatment guidelines about purulent meningitis in children were collected. Evidence-based evaluation was performed after data extrac-tion and quality evaluation. RESULTS:Finally 3 guidelines were enrolled in total,with development time ranging from 2004 to 2012,from USA,Britain and Australia,respectively. All of the recommendations were level B,scope and purpose and clarityshowed the higher scores in AGREEⅡ,more than 70%,and applicability showed generally low scores. Penicillin and cefotaxi-me were recommended in purulent meningitis of neonates,and vancomycin combined with cefotaxime or ceftriaxone were recom-mended for infants and children(it was combined with vancomycin when Streptococcus pneumoniae infection was suspected). The dose and duration of each guideline were certain different,and the period of treatment should be longer in neonates. In addition, the glucocorticoid was recommended in all guidelines. CONCLUSIONS:The recommendations of medicines for the treatment of pu-rulent meningitis are basically unanimous,with no regional difference,but there are some differences about dose and the course of treatment. In addition,the classification criteria of the levels of evidence and recommendation are still suboptimal,which needs fur-ther improvement. And guidelines on purulent meningitis should be improved inrigourandapplicabilityin future.

This study was aimed to establish a qualitative model of near-infrared spectroscopy in order to accurately and rapidly identify several mineral Chinese medicinals from fossil including Os Draconis, Dens Draconis, Fossil Shell of Spirifer, and Fossil Crabs. The near-infrared diffuse reflectance spectroscopy combined with OPUS software was used to analyze the spectral characteristics of these samples. The pattern recognition method was explored through cluster analysis. And the accuracy of the model was verified. The results showed that these mineral Chinese medicinals from fossil had their characteristics absorption so that they can be quickly and accurately differentiated from each other through pattern recognition method. It was concluded that based on near-infrared spectroscopic mod-eling, these mineral Chinese medicinals from fossil including Os Draconis, Dens Draconis, Fossil Shell of Spirifer, and Fossil Crabs can be quickly and accurately identified.

Objective:To develop a qualitative analysis model for the fast identification of Dens Draconis and its adulterants by NIR correlation coefficient method. Methods:On the basis of the traditional morphological identification, the spectra were collected u-sing the fiber accessory of a near-infrared spectroradiometer. The reference spectra were set up using the NIR spectra of certified Dens Draconis. The characteristic spectral section was chosen and the appropriate threshold was set to establish a qualitative analysis model for the rapid identification of Dens Draconis and its adulterant. Results:The spectral section of 5 000-4 200 cm-1 was selected as the characteristic spectral section, the correlation coefficient of Dens Draconis and its adulterant was calculated in training set samples, and 92. 67% was used as the threshold. Totally 10 batches of validation set samples were validated the qualitative analysis model, and the prediction accuracy was 90%. Conclusion:The method has good prediction ability, and can be used in the rapid identification of Dens Draconis and its adulterant.

Objective To study the clinical efficacy of the injection Salvia (freeze-dried, abbr: Salvia powder needle), with fallopian tube recanalization on the treatment of oviduct obstructive infertility. Methods One hundred and ninety-five patients of oviduct obstructive infertility were enrolled in this study and divided into drug group and control group. Salpingography with modified catheter, recanalization and perfusion operation were performed in both two groups. Salvia powder, gentamicin, α-ACT and dexamethasone were injected into test group, while Gentamicin, α-ACT and dexamethasone were injected into control group. Recanalization rate of fallopian tube, rate of intrauterine gestation and rate of ectopic pregancancy were measured and compared between two groups. Results Twelve months after operation, recanalization of fallopian tube of test group and control group was 94.39% and 85.87%, respectively. Twenty-four months after operation, intrauterine gestation rate of test group and control group was 50.00% and 35.71%, respectively. Conclusion Salvia powder combined with modified recanalization operation is helpful to improve the rate of intrauterine gestation.

Objective To investigate the effects of interferon alpha?2b(IFNα?2b)on serum Hepcidin in hepatitis C patients and its mechanism. Methods Hepatitis C patients were divided evenly into treatment group and control group according to whether they had received treatment with IFNα?2b in the past 3 months. The serum hepci?din was compared between the two groups. HepG2 cells and LO2 cells were treated for 24 hours at varied levels of IFNα?2b(0,50,100,200,400μL)and real?time PCR was used to detect the hepcidin,interleukin?6(IL?6)and signal transduction and transcription activator 3(STAT3)mRNA expression of cells. The protein levels of STAT3 and phosphorylated STAT3(pSTAT3)were measured by Western blot. The changes of these indexes were observed with the gradual increase of IFNα?2b levels. Results Serum Hepcidin level in the treatment group was significantly lower than the control(P<0.05). IFNα?2b inhibited the Hepcidin mRNA in HepG2 cells and LO2 cells. pSTAT3 was significantly decreased with the increased levels of IFNα?2b(P<0.05),and the expression of IL?6 and STAT3 had no significant changes with the increase of IFNα?2b. Conclusion The serum Hepcidin levels can be decreased because IFNα?2b suppresses the expression of Hepcidin,and its mechanism may be related with inhibited STAT3 pathway activation.

Objective To identify the efficacy and safety of aspirin in reducing the serum high sensitivity C reactive protein(hsCRP)level and preventing the internal arteriovenous fistulas(AVF)embolism in maintenance hemodialysis patients. Methods One hundred and ten hemodialysis patients using AVF more than 3 months were randomly divided into 2 groups,the intervention group(n=55,received aspirin 100 mg/d)and the control group(n=55).Examinations were performed at baseline and 6-month after treatment.Serum hsCRP level,platelet aggregates ratio(PAR),coagulation and inflammation indicators were measured.AVF embolism and the adverse events were monitored. Results Six months later.PAR and hsCRP level of the intervention group patients aged≤60 years decreased significantly [(68.14±8.45)%vs (82.37±9.12)%;(4.79±4.81)mg/L vs(6.94±10.26)mg/L,all P＜0.05],and were significantly lower as compared to.the control group[(68.14±8.45)%vs(74.7±11.50)%,(4.79±4.81)mg/L vs(5.12±9.25)mg/L,all P＜0.05].There were 2 cases of AVF embolism occured in both groups,which showed no statistical difierence (P=0.676).The incidence of adverse effeets was higher in the intervention group than that in the control group but no statistical significance was found (20.0%vs 7.2%,P=0.052),while the mortality rate had no difference between 2 groups (3.6%vs 0,P=0.495).Conclusion Use of aspirin 100 mg/d for 6 months can significantly reduce the serum hsCRP level and PAR in hemodialysis patients under 60-year-old without serious adverse reactions.

Objective To establish a quantitative measurement of flow field uniformity of mitral valve in vivo and investigate the correlation between the parameter of flow field uniformity and the degree of mitral stenosis. Methods The flow field uniformity downstream of mitral valve in normal cases and patients with mitral stenosis were studied using vector flow mapping(VFM) technique. Results The flow field uniformity parameter of standard deviation of velocity (Vsd) in patients with mitral valve stenosis was significantly higher than that in control group ( P <0. 05). There was a negative linear correlation between Vsd and effective orifice area(EOA) in patients with mitral valve stenosis (parasternal long-axis: r = - 0. 816, P = 0.000; apical four chamber: r = - 0. 825, P = 0. 000). Conclusions VFM can really reflect the flow field uniformity of normal cases and patients with mitral stenosis.

Objective To investigate the correlation between intima-media thickness(IMT)and elasticity of carotid in patients with type 2 diabetes accompanied hyperlipidemia by quantitative intima-media thickness(QIMT)and quantitative arterial stiffness(QAS)technique.Methods Fifty-six patients with type 2 diabetes accompanied hyperlipidemia were involved into the study as case group.Forty-eight healthy volunteers were supplied as normal control group in the same period.IMT,compliance coefficient(CC),distensibility coefficient(DC)and stiffness index(β)of carotid were acquired through QIMT and QAS.Case group was divided into case group 1(IMT＜0.9mm)and case group 2(IMT≥0.9 mm),and analysis was performed furtherly.Results β,triglyceride(TG),lowdensity lipoprotein(LDL),cholesterol(Ch),glycosylated hemoglobin(GHb)and IMT had significant differences in case group 1,case group 2 and control group(P＜0.05),control group＜case group 1＜case group 2.DC and CC had significant differences in case group 1,case group 2 and control group(P＜0.05),control group＞case group 1＞case group 2.There was significant positive correlation between β and age,GHb,LDL and IMT of carotid respectively(r=0.811,r:0.764,r=0.732,r:0.729,respectively,P=0.000).Conchmions IMT of carotid could be measured accurately by QIMT.Structure imaging and functional imaging of carotid might be combined organically through QIMT and QAS.Depth study about early change of carotid in structure and function could be performed with these two techniques.
