Diastolic and systolic dysfunction of cerebral artery is an important pathophysioiogical basis of the occurrence and development of cerebrovascular diseases, and is also the presence of decreased cerebrovascular reserve capacity. Cerebrovascular myogenic and metabolic regulation abilities can be evaluated by different methods so as to reflect cerebrovascular reserve capacity, of those, transcranial Doppler ultrasonography is the most widely used one. Various diseases, such as hypertension, diabetes mellitus, and carotid atherosclerosis also have great effect on cerebrovascular reserve capacity.

To review the research of block copolymer micelles as delivery system for poorly soluble(antineoplastic) carrier over the last 10 years,including the composition,preparation methods and factors which influence the loading efficiency,physicochemical properties,and targeting characteristics of block copolymer micelles.Block copolymer micelles are self-assembled structures formed from amphiphilic block copolymers by dispersing in aqueous media.The hydrophilic blocks of the copolymer form the outer shell of the micelle,while the hydrophobic blocks form the inner core,and the proper coreshell micellar architecture was constituted.Block copolymer micelles have a whole set of unique properties,such as small sizes,narrow particle size distribution,high drug loading capacities,and available disposition characteristics in the body.Block copolymer micelles have been found as promising drug carriers due to making poorly soluble antineoplastic lysis,toxicities and side effects decrease,bioavailability increase,and targeting the drugs to specific sites in a passive way or attaching ligands in an active way,which can be specifically(recognized) by receptors onto the surface of copolymers.

ObjectiveTo explore the effects of insomnia on heart rate variety(HRV) in aged hypertension patients. Methods259 subjects were divided into healthy group (74 cases),simple hypertension group (71 cases),coexisting hypertension and insomnia group (114 cases) which was sub-grouped to ＜5 years,5-9 years and ≥-10 years according to the duration of insomnia.All subjects had 24 h recordings of ECG.The data of HRV time domain (SDNN,SDANN and ASDNN) were collected and compared.ResultsHRV time domain was lower in healthy group than in the other two groups (F=12.02,10.54 and 4.27,P＜0.01),and decreased more significantly in coexisting hypertension and insomnia group compared with simple hypertension group(P＜0.01).The values of SDNN and SDANN in 5-9 years and ≥ 10 years subgroups decreased as compared with ＜ 5 years subgroup (F=8.63 and 4.54,P＜0.01),and these values further lower in ≥10 years subgroup than in 5-9 years subgroup (P＜ 0.01 ). ConclusionsInsomnia may lead to more serious disorder of automatic nervous system and further aggravated disorders appear in the elderly with hypertension along with increasing years of insomnia.

Objective To observe the suppressing effect of topical nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids on ultraviolet ray (UV)-induced erythema.Methods A solar simulator and an UV phototherapy device were used as light sources,respectively.Erythema reaction was induced on the back skin of 30 healthy volunteers by 1,2 and 3 minimal erythema doses (MED) of irradiation.Five preparations including butyl flufenamate 2.5％ ointment,butyl flufenamate 5％ ointment,the base of butyl flufenamate ointment,halometasone ointment,and diclofenac 1％ ointment,were applied to the irradiation sites respectively half an hour before or immediately after the irradiation.One irradiation site remained untreated and served as the control.The degree of erythema was evaluated by a chromameter at 4,24,and 48 hours after the irradiation.Intragroup and intergroup comparisons were done by t test and analysis of variance,respectively.Results When applied half an hour before solar-simulated irradiation,both 2.5％ and 5％ butyl flufenamate ointment totally suppressed the erythema reaction induced by 1-3 MED of UV irradiation,with no significant increase in erythema index at all the three time points after irradiation (all P ＞ 0.05); diclofenac 1％ only inhibited the erythema induced by 1 MED of UV irradiation at 4 and 48 hours,with no difference observed in erythema index between the baseline and these time points after irradiation; however,halometasone significantly aggravated the erythema reaction (P ＜ 0.05).Neither NSAIDs nor corticosteroids applied immediately after solar-simulated irradiation showed statistical effect on the degree of UV-induced erythema.When applied immediately after irradiation using the phototherapy device,butyl flufenamate 2.5％ ointment,butyl flufenamate 5％ ointment and halometasone ointment all induced a significant reduction in erythema reaction at 4 hours after 1 MED of irradiation (all P ＜ 0.05),and diclofenac caused a statistical decrease in erythema reaction at all the time points after 1-3 MED of irradiation (all P ＜0.05).Conclusions Topical use of butyl flufenamate before UV irradiation can effectively inhibit erythema reaction induced by 1-3 MED of irradiation.When applied immediately after irradiation,diclofenac shows the strongest erythema-suppressive effect,followed sequentially by butyl flufenamate and halometasone.

Objective To explore the thyroid function changes of episodes period and remissions period in children with primary nephrotic syndrome (NS).Methods The urinary protein quantitation and serum albumin,total cholesterol,thyroid hormone level [total triiodothyronine (TT3),total thyroxine (TT4),free triiodothyronine (FT3),free thyroxine (FT4) and thyroid stimulating hormone (TSH)] of episodes period and remissions period in 15 children with primary NS were retrospectively analyzed.Results There were statistical differences in urinary protein quantitation and serum albumin,total cholesterol in children with NS between episodes period and remissions period (P ＜ 0.05).The TT3,TT4,FT3,FT4 in episodes period were significantly lower than those in remissions period [(0.6 ± 0.3) μ g/L vs.(1.3 ± 0.3) μ g/L,(40.0 ± 23.0)μ g/L vs.(68.0 ± 15.0) μ g/L,(1.6 ± 0.3) pmol/L vs.(3.3 ± 0.3) pmol/L,(8.6 ± 2.5) pmol/L vs.(12.2 ± 2.0) pmol/L],TSH was significantly higher than that in remissions period [(5.6 ± 2.1) mU/L vs.(2.5 ± 1.1) mU/L],there were statistical differences (P ＜ 0.05).Conclusions Thyroid function of episodes period in children with primary NS is decreased temporarily,associated with heavy proteinuria leads to thyroid hormone missing from urine.Detecting thyroid function plays an important role in estimating the state and guiding the treatment of primary NS.

Objective To investigate whether genotypes of CYP3A5,MDR1 and cyclooxygenase-2 are associated with the sensitivity of vinorelbine-platinum to NSCLC.Methods The genotypes of CYP3A5(*3),MDR1 (2677G>T at exon 21 and 3435C>T at exon 26 and their haplotypes),cyclooxygenase-2 (-1 195G>A) were determined by RFLP-PCR and chemotherapy responses were analyzed in 69 non-small-celllung cancer (NSCLC) Chinese Han patients.They received a combination chemotherapy of vinorelbine-cispla-tin.Chi-square test was used to investigate the potential association of genotype with chemotherapy response.OR and 95% C1 were calculated.Results The 3435 CC genotype was associated with a significantly betterchemotherapy response compared with the combined 3435 CT and 1Tr genotypes(P=0.033).The 2677 GG genotype was also associated with a significantly better chemotherapy response compared with the combined 2677 GT and IT genotype(P=0.012).Moreover.patients with the 2677 G-3435 C haplotype seemed to have a better response to chemotherapy compared with those with the other haplotypes(P=0.063).CYP3A5*3 was not likely to correlate with sensitivity of vinorelbine-platinum to NSCLC.Cyclooxygenase-2-1195G>A was likely to have better response to vinorelbine but not statistically significant(P=0.067).Conclusion Polymor-Dhisms of MDR1 3435 C>T and MDR1 2677 G>A/T can be used for predicting treatment response to vinorel-bine-cisplatin chemotherapy in NSCLC patients.

Aim: To observe the effect of ursolic acid(UA)on the proliferation of rat vascular smooth muscle cell(VSMC)induced by high-level glucose and explore its relationship with p38MAPK signal transduction pathway.Methods: The proliferation of VSMC induced by high-level glucose(25 mmol/L glucose)was adopted as model,the inhibition of UA on the proliferation of VSMC was measured by MTT assay,and the expression lev-els of phospho-p38MAPK was detected by cell-based ELISA as well as the expression of c-fos protein was exam-ined by SABC method.Results: UA(20 μmol/L and 40 μmoL/L)inhibited glucose-induced proliferation of VSMC(P <0.05).Compared with the group subjected to glucose induction,UA decreased the expression levels of phosphorylated p38MAPK(P < 0.05),and also inhibited c-fos expression.Conclusion: UA suppressed glucose induced proliferation of VSMC,which might be related to the suppression of the activation of p38MAPK signal transduction pathway,and thereby down-regulated c-fos expression.
