OBJECTIVETo observe the clinical effects of essential hypertension treated with acupuncture at Siguan [Hegu (LI 4) and Taichong (LR 3)], Quchi (LI 11) and Xingjian (LR 2).

METHODSSixty cases of essential hypertension were randomly divided into an acupuncture group and a medication group, 30 cases in each group. Two groups of acupoint, which were (1) Siguan [Hegu (LI 4) and Taichong (LR 3)] and (2) Quchi (LI 11), Xingjian (LR 2), were selected alternatively in the acupuncture group, once everyday. In the medication group, captopril was prescribed for oral administration 25 mg per time, three times per day. Seven days made one session in both groups and totally three sessions were required.

RESULTS(1) After treatment, the blood pressure were decreased significantly in the two groups (all P < 0.01). Compared with the medication group, the diastolic pressure after 14 days, 21 days of treatment in the acupuncture group was decreased significantly (both P < 0.01). (2) In the terms of TCM syndrome score, the improvement of dizziness, soreness and weakness of waist and knees, palpitations was significant in the acupuncture group compared with that in the medication group(all P < 0.05). (3) The acupuncture group had less adverse reactions compared with the control group (P < 0.05).

CONCLUSIONAcupuncture at Hegu (LI4) and Taichong (LR 3), Quchi (LI 11) and Xingjian (LR 2) can effectively decrease blood pressure; the effect of controlling diastolic pressure is better than captopril. It can also improve the symptoms of dizziness, soreness and weakness of waist and knees, and palpitations.

In recent years a number of qualitative research methods have gained popularity within the health care arena. Despite this popularity, different qualitative analysis methods pose many challenges to most researchers. The present paper responds to the needs expressed by recent Chinese medicine researches. The present paper is mainly focused on the concepts, nature, application of framework analysis, especially on how to use it, in such a way to assist the newcomer of Chinese medicine researchers to engage with the methodology.

OBJECTIVE TNF- related apoptosis- inducing ligand(TRAIL)is a promising cancer therapeutic agent due to its minimal toxicity to normal tissues and remarkable apoptotic activity in tumors. However, most breast cancer cells are resistant to TRAIL- induced apoptosis. Our objectives are to investigate the underlying molecular mechanisms and to develop strategies to overcome such resistance. METHODS To identify modulators of TRAIL-induced apoptosis, we carried out a genome wide siRNA screen. To validate the screening result, we either silenced or overexpressed the identified genes in various breast cancer cells and changes in growth and TRAIL-induced cell apoptosis were determined in vitro and in an orthotopic xenograft mouse model. Finally, we investigated whether small molecules targeting the identified genes improve the effectiveness of TRAIL-therapy. RESULTS We unexpectedly identified androgen receptor (AR) to be responsible for TRAIL resistance. While AR is classically viewed as the key factor in prostate cancer progression, we found that AR expression levels were markedly elevated in human invasive breast cancer specimens including triple- negative breast cancers (TNBC) that are highly aggressive with poor prognosis. Importantly, breast cancer cell lines express different levels of AR that correlated with their TRAIL resistance. AR overexpression in MDA- MB- 231 and MDA- MB- 436 cells suppressed the TRAIL sensitivity whereas knockdown of AR rendered MCF-7 and MDA-MB-453 cells sensitive to TRAIL-induced apoptosis. AR overexpression also induced TRAIL resistance in breast tumors in vivo. Further, we observed an upregulation of the TRAIL receptor, death receptor 5 (DR5) in breast cancer cells, following the removal or inhibition of AR by its antagonists Casodex and MDV3100. Treatment with AR antagonists also enhanced TRAIL- induced breast cancer cell apoptosis. CONCLUSION AR signaling suppresses TRAIL-induced breast cancer cell apoptosis, in part, by suppressing DR5 expression, and a combination of AR antagonists together with TRAIL may be a novel and effective therapy for TNBC.

A method for the determination of Fe, Co, Mn and Ni in synthetic diamonds by inductively coupled plasma atomic emission spectrometry ( ICP-AES) was proposed. The synthetic diamond sample was decomposed completely, while the sample was burned in air at 1000 ℃ for 10 h, and then a mixed acid of H2 SO4 , aqua regia and HClO4 was used for the dissolving the residue of the sample. In this method, the limits of detection of Fe, Co, Mn and Ni were 0. 0147, 0. 0018, 0. 0006 and 0. 0027 mg/L, respectively. Under the optimum condition, Fe, Co, Mn and Ni in synthetic diamond sample were determined. The values of RSDs (n=7) were less than 0. 5%. The recoveries of added standard were 94. 0%-105. 0%.

A method for the simultaneous determination of oxygen and nitrogen in synthetic diamonds by inert gas high temperature extraction-impulse heating method was proposed. The sample weight, the selection of analysis power and the calibration curves of oxygen and nitrogen were discussed. Oxygen and nitrogen in analytical samples are determined. Values of RSDs (n=7) for oxygen and nitrogen were less than 4. 5% and 4. 0% respectively. The analytical results of oxygen and nitrogen obtained by the proposed method were in good agreement with those by inert gas fusion-impulse heating method.

OBJECTIVE: To study the expression of interferon-λ1 (IFN-λ1) in respiratory epithelial cells in children with human rhinovirus (HRV) infection. METHODS: Sputum samples and nasopharyngeal swabs were collected from the children who were hospitalized due to acute respiratory infection from February to October, 2017. Bacterial culture was performed, and nucleic acid test was performed for 11 respiratory pathogens. A total of 90 children with positive HRV alone were enrolled as the HRV infection group, and 95 children with positive respiratory syncytial virus (RSV) alone were enrolled as the RSV infection group. A total of 50 healthy children who underwent outpatient physical examination during the same period of time and had negative results for all pathogen tests were enrolled as the healthy control group. Nasopharyngeal swabs were collected from all groups, and quantitative real-time PCR was used to measure viral load and the mRNA expression of IFN-λ1. RESULTS: In the HRV infection group, there was no significant difference in the mRNA expression of IFN-λ1 between boys and girls and across all age groups (P>0.05). In the HRV infection group, there was no correlation between the mRNA expression of IFN-λ1 and HRV load (P>0.05). The mRNA expression of IFN-λ1 in the HRV infection group was significantly higher than that in the healthy control group (P<0.05), but significantly lower than that in the RSV infection group (P<0.05). CONCLUSIONS HRV can induce the expression of IFN-λ1 in respiratory epithelial cells, suggesting that IFN-λ1 may play an important role in anti-HRV infection in children.

OBJECTIVE: To explore the effect and toxicity profile of recombinant human interleukin 11(rhIL-11) on the platelet after hematopoietic stem cell transplantation in patients with leukemia. METHODS: Twenty-four patients with acute or chronic leukemia treated by allogeneic peripheral blood stem cell transplantation (PBSCT) were randomly divided into a test group and a control group. The patients in the test group were treated with rhIL-11 since the 13th day after PBSCT (1.5mg/d),while the control group were given symptomatic treatment. RESULTS: The average time for the platelet to recover to the level of 20 x 10(9)/L was 20.8 days in the test group, and 26.0 days in control group respectively, there was significant difference (P<0.01). The average time for the platelet to recover to the level of 50 x 10(9)/L was 25.7 days in the test group, and 32.3 days in the control group respectively, there was also significant difference (P<0.01). The average time for the platelet transfusion was 2.2 in the test group, 4.1 in the control group, and there was significantly different (P<0.01). The average number of megakaryocytes was 12.2 in the test group, 4.8 in the control group on 30th day after the transplantation,and there was significant difference(P<0.01). The main side effects of rhIL-11 were nausea, vomit, debility, headache, dizzy and pain of injection site, and the degree was all Iapproximately II grade. CONCLUSION rhIL-11 has definite recuperative effect on the recovery of the platelet after PBSCT. There is little side effect, and it can be accepted.
