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.

AIM: To evaluate the effect of carbon monoxide(CO) on the permeability of brain blood barrier(BBB) in cerebral ischemic rats. METHODS: SD rats were divided into three groups. Saline, hemin or ZnPP were injected intraperitoneally 12 h before middle cerebral artery occlusion (MCAO), respectively. The concentration of blood CO and the permeability of BBB at 24 h after MCAO were measured. RESULTS: The CO concentration in blood in hemin group was higher than that in saline group( P 0.05). CONCLUSION: CO reduced the permeability of BBB as a messenger gas molecular when its intrinsic concentration was elevated.

OBJECTIVETo partially clone and compare the quantitative expression of tooth development-related gene Barx1 in different teeth of the mini-pig embryo at embryonic day 40, and to investigate the relationship between Barx1 spatial quantitative expression and tooth morphogenesis.

METHODSThe mini-pig Barx1 genes was partially cloned and the mRNA sequences of human Barx1 genes was aligned with expressed sequence tags (EST) of pig by basic local alignment search tool (BLAST), which were assembled with DNAman v5.2.2. With designed primers, Barx1 was partially cloned in use of reverse transcription polymerase chain reaction (PCR), and tested by BLAST with all the species in NCBI database and confirmed as one part of target gene. Laser capture microdissection was used to collect tooth samples from frozen sections which were prepared before in -80°C freezer. Real-time PCR was carried out to analyze quantitative expression in different teeth.

RESULTSPartial mini-pig Barx1 gene of 698 bp was cloned. Real-time PCR showed that, glyceraldehyde-3-phosphate dehydrogenase used as loading control, the figures of 2(-ΔCT) of lower deciduous incisor, canine, the third premolar and molar were 0.000 249, 0.000 715, 0.026 096 and 0.112 656, respectively. There was a trend of increasing expression from anterior to posterior teeth.

CONCLUSIONSBarx1 gene could be related to the number or differentiation of tooth cusps.

OBJECTIVETo study the clinical efficacy and adverse reaction of compound Duzhong Jiangu granule (CDJG) on knee joint osteoarthritis (KJO) of Gan-Shen deficiency with stasis in tendon and muscle syndrome.

METHODSThe randomized controlled method was adopted in this study, comparative study was conducted in 400 patients in the treated group treated with CDJG and 200 patients in the control group treated with Zhuanggu Guanjie pill (ZGP).

RESULTSThe total effective rate in the treated group was 92% and the curative-markedly effective rate was 47%, which were higher than those in the control group respectively. Moreover, CDJG showed superiority in improving symptoms and with shorter initiating time of action as compared with ZGP. However CDJG had the effect more favourable for patients of mild condition.

CONCLUSIONCDJG is a kind of effective and safe medicine for treatment of KJO.

Objective To investigate the polymorphism of human cytomegalovirus（HCMV）UL146 gene in clinical strains,and to evaluate its clinical diagnostic and therapeutic value of gene.Methods The UL146 gene of clinical strains was examined by quantitative polymerase chain reaction（Q-PCR）or general polymerase chain reaction（PCR）.Positive samples of PCR amplification were sequenced and analyzed.Results High variability of UL146 gene was found among 28 HCMV strains.According to phylogenetic analysis,all sequences of UL146 in clinical strains could be divided into three types and four subtypes.Chemokine ELRCXC region was highly conserved in all sequences.Conclusion HCMV-UL146 genes showed a high degree of polymorphism,and its encoded chemokine ELRCXC region was highly con-served.The relationship between HCMV-UL146 gene′s polymorphism and different clinical symptoms of HCMV infection was unclear.

BACKGROUNDOur previous study confirmed that oligodendrogliomas had higher frequency of chromosome 1p/19q deletion. In order to improve the diagnostic criteria and to predict the prognosis of oligodendroglioma patients, the status of chromosome 1p/19q deletion, the methylation of O(6)-methylguanine-DNA methyltransferase (MGMT), and the expression of p53 protein were evaluated and investigated in relation to patients' outcomes.

METHODSMethylation of MGMT in 73 cases was analyzed by nested methylation-specific PCR (MSP). The levels of MGMT and p53 protein were tested with immunohistochemistry. Pearson's chi-square test and Fisher's exact test were used. Multivariate and Kaplan-Meier analysis were performed to determine patients' outcomes.

RESULTSBoth oligodendrogliomas and astrocytic gliomas exhibited frequent methylation of MGMT. However, the results of MSP did not completely correspond to that of the immunohistochemical staining for MGMT. The expression of p53 protein was more frequently observed in patients without a 1p or 19q deletion in anaplastic oligodendrogliomas (P = 0.032, 0.025). In low-grade oligodendrogliomas, methylation of MGMT was more frequent in patients with 1p/19q deletion than in patients with 1p/19q intact (P = 0.038). Patients with oligodendrogliomas with 1p/19q loss of heterozygosity and p53-negative showed a longer progression-free survival.

CONCLUSIONDetection of chromosome 1p/19q status combined with p53 protein immunohistochemistry might be beneficial to improve the pathological diagnosis and to determine the prognosis of patients with oligodendrogliomas.

Objective To develop the method of 16S rRNA gene clone library for tick bacterial flora analysis, and to analyze the detection effective of pathogens in tick and capacity of bacterial flora diversity. Methods Primers were designed according to the specific gene of Borrelia burgdorferi, Bartonella henselae, Anaplasma phagocytophilum, Ehrlichia chaffeensis and templates were choosen by positive PCR result to amplify the DNA extracted from the ticks. One set of primers targeting 16S rRNA gene conserved region were chosen to amplify certain fragments, DNA extraction, PCR reaction, cloning and sequencing. Nucleotide sequences were compared with GenBank database. Calculated Coverage values of clone library and Shannon-Wiener diversity index. Results Sixteen defined genus-or species-bacteria were detected in 103 valid sequences. Eight species were edge type (Clone No. > 5). Three kinds of pathogens were identified (Borrelia burgdorferi, Bartonella henselae and Rickettsia sp). Three kinds of pathogens were not edge type(Clone No. < 5). Coverage value was 96.11%, and Shannon-Wiener index was 2.40. Analysis results of cloning sequence showed that tick-parasitic bacteria mainly were α and γ deformation mycetes which accounted for 56.25% (9/16). Conclusions The 16S rRNA gene sequences technology could make relative quantitative of bacterial flora, and detect many kinds of pathogens in tick. It's a good method for detection of pathogens and bacterial flora analysis.
