Objective: To observe the clinical efficacy of acupuncture plus auricular point sticking for tension-type headache (TTH). Methods: A total of 90 TTH patients were divided into an acupuncture group, an auricular point sticking group and an observation group by random number table method, with 30 cases in each group. Patients in the observation group received acupuncture plus auricular point sticking for treatment, while those in the acupuncture group only received acupuncture and those in the auricular point sticking group only received auricular point sticking for treatment. The headache attack frequency and the scores of visual analog scale (VAS), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were observed before treatment, after treatment and 3 months after treatment. The clinical efficacy was evaluated at the follow-up of 3 months after treatment. Results: At follow-up, there were significant differences in clinical efficacy among the three groups (P<0.01 or P<0.05), and the clinical efficacy ranking from high to low was the observation group, the acupuncture group and the auricular point sticking group. After treatment and at follow-up, the VAS score, headache attack frequency, SAS and SDS scores in the three groups were significantly lower than those before treatment (all P<0.01). The above four results in the observation group were lower than those in the acupuncture group and the auricular point sticking group at the same time point (all P<0.01); VAS score in the acupuncture group was lower than that in the auricular point sticking group (both P<0.05). At follow-up, the headache frequency in the acupuncture group was lower than that in the auricular point sticking group (P<0.05). Conclusion: Either using acupuncture and auricular point sticking together or separately can reduce the headache degree of TTH patients, reduce the number of headache attacks, and relieve anxiety and depression. The efficacy of acupuncture plus auricular point sticking is most significant.

Objective To investigate the role of Gly82Ser polymorphism of receptor for advanced glycation end-products (RAGE) in the genesis and progression of colon cancer in Chinese population.Methods Using the method of PCR-restriction fragment length polymorphism (PCR-RFLP),the Gly82Ser genotype of RAGE were examined in 90 colon cancer patients and 78 control subjects age and sex matched.Analyses stratified by TNM and tumor differentiation were conducted to check the associations of the Gly82Ser gene polymorphisms in RAGE and development of colon cancer.Results The genotype distribution was in agreement with that predicted under Hardy-Weinberg equilibrium for both patients and controls (both P ＞ 0.05).With the GG genotype as reference,the odds ratio (OR) for heterozygous GG and carriers with S allele (GS and SS) were 2.037 (95％ CI:1.207-3.438) and 2.022 (95％ CI:1.275-3.208),respectively,which had a significantly higher risk of colon cancer.Moreover,the elevated colon cancer risk was especially evident in patients with TNM (Ⅲ + Ⅳ) and/or patients with poor differentiation by stratification analysis (OR,3.575,95％ CI:1.495-8.550 and OR,3.580,95％ CI:1.390-9.217,respectively).Conclusions The RAGE Gly82Ser polymorphism may confer not only an increased risk of colon cancer but also with invasion of colon cancer in the Chinese population.

Objective To study the effects of lead exposure on expression of nerve growth factor(NGF)gene in the rat hippocampus,and explore the molecular toxicological mechanism of the learning and damage induced by lead exposure. Methods Using the reverse transcription-polymerase chain reaction(RT-PCR)and in situ hybridization,NGF mRNA levels in the hippocampus of normal and lead exposure rats were investigated. Results NGF mRNA presented in the normal hippocampus of rats.NGF mRNA levels in the hippocampus were significantly decreased by lead exposure.There was a negative correlativity between the expression of nerve growth factor mRNA in the hippocampus and the time of lead exposure.Conclusion Lead can downregulate the expression of nerve growth factor gene in the rat hippocampus.

Hydrophidae, one of the precious traditional Chinese medicines, is generally drily preserved to prevent corruption, but it is hard to identify the species of Hydrophidae through the appearance because of the change due to the drying process. The identification through analysis on gene barcode, a new technique in species identification, can avoid the problem. The gene barcodes of the 6 species of Hydrophidae like Lapemis hardwickii were aquired through DNA extraction and gene sequencing. These barcodes were then in sequence alignment and test the identification efficency by BLAST. Our results revealed that the barcode sequences performed high identification efficiency, and had obvious difference between intra- and inter-species. These all indicated that Cyt b DNA barcoding can confirm the Hydrophidae identification.

Objective:To analyze the characteristics of hospital infection of hematological disease, so as to provide reference for clinical therapy. Methods: Bacterial strains and antimicrobial resistance of pa-tients with hospital infection in Department of Hematology, Peking University Third Hospital from Jan. 2011 to Dec. 2013 were identified and analyzed retrospectively. The specimens were from their blood, urine, sputum, throat swabs and etc. Results:Among the total of 168 isolates of bacteria,the majority of the bacteria strains were from sputum (42. 9%);114(67. 9%) bacteria strains were gram negative and 54(32. 1%) bacteria strains were gram positive;the pathogen testing showed that 20. 8% were Pseudo-monas aeruginosa,18. 5% Escherichia coli,17. 9% Staphylococcus aureus, 9. 5% Klebsiellar pneumonia, 5. 9% Staphylococcus epidermis and 27. 4% other bacteria ;The gram negative bacilli to cefepime, ami-kacin and carbapenems showed the lowest antimicrobial resistance rates, and S. aureus showed the lowest antimicrobial resistance rates to vancomycin and linezolid. Conclusion:Patients with hemopathy are the main population of hospital infections, the gram negative bacteria are the most common pathogens. It is very important to promptly know the change in distribution of the pathogens in order to rationally select antibiotics and reduce the incidence of bacterial infections.

Objective To evaluate the effects of nerve growth factor-beta (NGF-β) pretreatment on cell apoptosis induced by endoplasmic reticulum stress during ischemia-reperfusion in isolated rat hearts.Methods Male Sprague-Dawley rats,weighing 180-220 g,were anesthetized with intraperitoneal 10％ chloral hydrate 300 mg/kg.The hearts were excised and perfused in a Langendorff apparatus with K-H solution aerated with 95％ O2 and 5％ CO2 at 37 ℃.Thirty-two isolated rat hearts were randomly divided into 4 groups (n =8 each) using a random number table:control group (group C),I/R group,NGF-β pretreatment group (group N) and NGF-β combined with K252a (trkA receptor antagonist) pretreatment group (group N + K).In group C,the hearts were continuously perfused with K-H solution for 195 min.The hearts were perfused with K-H solution for 45 min in group I/R.In N and N + K groups,the hearts were perfused with K-H solution for 15 min,and then with K-H solution containing 0.1 μg/ml NGF-β and 0.1 μg/ml NGF-β mixed with 100 nmol/L K252a,respectively,for 30 min.The perfusion was suspended for 30 min followed by 120 min of reperfusion with K-H solution in I/R,N and N + K groups.HR,left ventricular end-diastolic pressure (LVEDP),left ventricular developed pressure (LVDP) and + dp/dtmax were measured at the end of 15 min equilibration (baseline) and at 5,30,60 and 120 min of reperfusion.Myocardial specimens were obtained at 120 min of reperfusion for detection of myocardial apoptosis (by TUNEL) and expression of glucose-related protein 78 (GRP78),CCAAT/enhancer-binding protein homologous protein (CHOP),and caspase-12 (by Western blot analysis).Apoptosis index was calculated.Results Compared with group C,HR,LVDP and + dp/dtmax were significantly decreased,and LVEDP,apoptosis index and expression of GRP78 and CHOP were increased in I/R and N groups,and the expression of caspase-12 was upregulated in I/R group.Compared with group I/R,HR,LVDP,and + dp/dtmax were significantly increased,and LVEDP,apoptosis index and expression of GRP78,CHOP and caspase-12 were decreased in group N,and the expression of GRP78 was down-regulated in group N + K.There was no significant difference in cardiac function indexes between group I/R and N + K.Compared with group N,HR,LVDP and + dp/dtmax were significantly decreased,and LVEDP,apoptosis index,and expression of GRP78,CHOP and caspase-12 were increased in group N + K.Conclusion NGF-β pretreatment can protect the isolated rat hearts against ischemia-reperfusion injury,and inhibition of the endoplasmic reticulum stress-triggered cell apoptosis after activating trkA receptors is involved in the mechanism.

ObjectiveTo analyse treatments and prognostic factors of T cell non-Hodgkin lymphoma (T-NHL). MethodsNinety-one patients with T-NHL were retrospectively analyzed, and clinical features,histopathology, laboratory data were included in Kaplan-Meier and prognostic analysis. Results Median age was 38 years,58 (63.7 ％) had high-intermediate and high risk by IPI,72 (79.1％) presented with advanced stage disease,extranodal disease was present in 64.8 ％ of patients.The overall response rate (ORR) for the whole group was 63.8 ％,and the estimated 3,5-year ORR were 55.5 ％,41.3 ％ respectively.Compared with CHOP-like regimen, the addition of etoposide could improve the survival of patients, meanwhile radiation therapy could improve the outcome of patients with NK/T cell lymphoma and mediastinal bulky disease, and consolidation chemotherapy with HSCT could improve the survival and reduce the recurrence of patients.Clinical stage,B symptoms,ECOG score,the level of LDH,extranodal involvment,anemia,initial treatment outcome, IPI score, the level of serum albumin and fibrinogen were predictive to overall survival. Cox multivariate analysis showed initial treatment outcome and B symptoms were independent prognostic factors.IPI and m-PIT were useful for stratified patients into different prognostic risk groups. Conclusion T-NHL is a heterogeneous group of malignancies with an inferior long term outcome. New treatment modality needs to be explored for these patients,and new drugs and HSCT may be good choices.

Objective To evaluate the role of 1-phosphatidylinositol 3-kinase (PI3K) signaling pathway in nerve growth factor-beta (NGF-β)-produced mitigation of cell apoptosis induced by endoplasmic reticulum stress during hypoxia-reoxygenation (H/R) in rat cardiomyocytes.Methods H9c2 cells were seeded in 96-well plates at a density of 5× 105 cells/ml (100 μl/well).The wells were randomly divided into 5 groups (n =15 each) using a random number table: control group (group C);group H/R;NGF-β group (group N);NGF-β+NGF receptor trkA antagonist K252a group (group N+K);NGF-β+ PI3K inhibitor LY294002 group (group N+L).The cells were exposed to 95％ N2-5％ CO2 for 4 h in an anaerobic incubator, followed by reoxygenation in a standard incubator for 4 h in H/R, N, N+K and N+L groups.In addition, the cells in N, N + K and N + L groups were incubated in a standard incubator containing NGF-β, the mixture of NGF-β and K252a and the mixture of NGF-β and LY294002, respectively, during reoxygenation, and the final concentrations of NGF-β , K252a and LY294002 were 50 ng/ml, 100 nmol/L and 50 μmol/L, respectively.The cell viability was detected by using CCK-8 assay, and the cell survival rate was calculated.The cell apoptosis was examined by flow cytometry, and apoptosis rate was calculated.The expression of glucose-regulated protein 78 (GRP78), C/EBP homologous protein (CHOP), caspase-12, Akt and phosphorylated Akt (p-Akt) was detected by Western blot.The ratio of p-Akt to Akt was calculated.Results Compared with group C, the cell survival rate was significantly decreased, and the apoptosis rate was increased in H/R and N groups, and the expression of GRP78, CHOP and caspase-12 was significantly up-regulated in group H/R, and p-Akt/Akt was significantly increased in group N (P＜0.05).Compared with group H/R, the cell survival rate was significantly increased, the apoptosis rate was decreased, the expression of GRP78, CHOP and caspase-12 was up-regulated, and p-Akt/Akt was increased in group N (P＜0.05), and no significant change was found in the parameters mentioned above in N+K and N+L groups (P＞0.05).Compared with group N, the cell survival rate was significantly decreased, the apoptosis rate was increased, the expression of GRP78, CHOP and caspase-12 was up-regulated, and p-Akt/Akt was decreased in N+K and N+L groups (P＜0.05).Conclusion NGF-β can mitigate the cell apoptosis induced by endoplasmic reticulum stress during H/R, and activation of PI3K signaling pathway is involved in the mechanism.
