This article reviewed the feature and the advances in the application of micellar electrokinetic capillary chromatography(MECC),an important mean of high performance capillary electrophoresis(HPCE),for the analysis of complicated component of medicine,.The analysis of multi-component of routine medicine,chiral drugs,illicit drugs,Chinese medicine,drug and its metabolites were introduced.

MIC,according to which,the antibiotics frequently used for treating respiratory infections were divided into three groups:Time-dependent(with minimal or no PAE),Concentration-dependent(with PAE),Time-dependent and Concentration-enhanced(with PAE),In addition,the most appropriate antibiotic administration methods are also explored respectively in the article.Finally,several measures of preventing emergence of resistance are proposed based on the theory of MPC.

Objective:To observe the inhibitory effects of survivin-specific siRNA on human lung cancer cell lines with different P53 statuses,and to analyse the relationship between P53 and survivin in vitro.Methods:A549(wild-type P53)and H1299(P53 absent)cells were transfected with chemosynthetic survivin siRNA.The effect of siRNA on cell proliferation was analysed by MTT assay.The changes of cell cycle and apoptosis were examined by flow cytometry.The expression of survivin mRNA was detected by RT-PCR.The protein expression of survivin,P53,P21 and PARP was examined by Western blotting.Results:Endogenous survivin level in A549 cells was lower than that in H1299 cells.The mRNA and protein expression of survivin was significantly lower in siRNA group than in blank control group and non-silencing siRNA group(P

The resection of lateral skull base tumour has always been a crucial and difficult aspect of skull base surgery.Its operation development has experienced several evolutionary phases,including unaided eye-surgery which could result in huge trauma,microsurgery and completely endoscopic surgery.At present,the endoscopic technique known for its panoramic visibility,minimal invasion and extensive scope of operation,has opened up a brand new perspective for the lateral skull base tumour surgery.Currently,the approach of lateral skull base tumour endoscopic surgery can be generalized as endoscopic transmaxillary approach (ETA).And based on different pathways and methods to expose the maxillary sinus,ETAs can be divided into three,endonasal transmaxillary approach(ENTA),endoscopic sublabial transmaxillary approach (ESTA) and combined approach,while ENTA includes ipsilateral endonasal transmaxillary approach (IENTA),prelacrimal recess approach (PRA),contralateral endonasal transseptal approach (CENTA) and transnasal Denker approach.In this paper,on the basis of the summarization of ETAs related historical evolution,anatomical studys and clinical researches,the merit and demerit of all sorts of ETAs are compared and analyzed.We hope this review could act as a reference for selecting the personalized endoscopic surgery approach of lateral skull base tumour.

Objective:To evaluate the clinical efficacy of telmisartan in patients with mild to moderate hypertension by observing the 24 hour mean blood pressure before and after treatment respectively.Methods:Twenty-six patients with mild to moderate hypertension took telmisartan 80mg once daily.After the treatment of telmisartan,ambulatory blood pressure monitoring (ABPM) was done.Results:After administration of telmisartan,24 hour mean blood pressure,blood pressure in the day and night decreased(P

Objective: To study the lung tissue TLR4 expression and airway hyperresponsiveness(AHR) in the mice infected by respiratory syncytial virus(RSV).Methods:16 clean,6 weeks old BALB/c mice were divided into two groups equally(RSV group and control).One week after RSV infection,AHR was detected by inhaling the increased concentration of methacholine,TLR4 mRNA expression was measured by RT-PCR methods,and the correlation between AHR and TLR4 expression was also analyzed.Results:An important difference was detected in two groups' airway resistance when the inhaled concentration of methacholine was 3.2g/L(P

Objective:To investigate the association of a(TA)n dinucleotide repeat polymorphism with unknown aetiology hypomenorrhea.Methods:100 normal menstruation person(control group) and 100 hypomenorrhea patients(case group)were recruited.they all came from southen-western China.The(TA)n dinucleotide repeat in ERa gene upstream hypervariable region were purifed,cloned and sequence analysed.we observe the ERa gene(TA)n dinucleotide repeat polymorphism distribution in the two groups.Results:All samples exhibted 7 different alleles.The(TA)n dinucleotide repeats were 11~17,The most prevalent allele was TA14 repeat in control group.The distribution of the different alleles of the(TA)n dinucleotide repeat sequence in the group and control group has significant difference(?2=13.412,P =0.037).Fisher's exact test was applied to compare the frequency of each a1lele between two groups.The frenquency of the TA13 allele was found to be significantly greater in hypomenorrhea group(P =0.006),and the frenquency of the TA15 allele was less in the group(P =0.033).Conclusion:A(TA)n dinucleotide repeat sequence which is in ERa gene upstream hypervariable region was associated with unknown aetiology hypomenorrhea.The TA13 allele was found to be associated with unknown aetiology hypomenorrhea and may be a risk factor;whereas TA15 allele may be a protective factor for patients.

Objective: To evaluate the quality of Radix bupleuri from different producing areas and make a comparison by using grey correlation analysis(GRA)and principal components analysis(PCA).Methods: Fifteen samples of Radix bupleuri were collected from different producing areas.The percentage of total ash, acid-insoluble ash, extract, saikosaponin a and saikosaponin d of Radix bupleuri from different habitats were determined.The grey correlation quality evaluation model was built for Radix bupleuri from different producing areas and the results were compared with those of PCA.Results: According to the grey correlation analysis on components in the different batches of Radix bupleuri , the samples from Shaanxi province were the most highly correlated with the optimal reference sequence (0.79), which suggested the best quality.Radix bupleuri Fructus from Hebei province was the most poorly correlated with the optimal reference sequence (0.23), which showed the worst quality.The results were basically identical with those of PCA, indicating good repeatability and stability.Conclusion: Grey incidence degree method and the established Radix bupleuri quality evaluation models can be used to evaluate the quality of Radix bupleuri .
