This study was aimed to explore the clinical effect of San-Jiao (SJ) acupuncture combined with Chinese medicine and Cisapride tablets in the treatment of senile constipation. A total of 118 patients were selected according to the inclusion criteria. According to the visiting sequence, patients were randomly divided into the acupuncture with Chinese medicine group of 60 cases and drug group of 58 cases. In the acupuncture with Chinese medicine group, SJ acupuncture was combined with Huang-Di (HD) powder in the treatment. In the drug group, Cisapride tablets were applied. Both groups were treated for 20 times. The scale was used in the comprehensive evaluation of integral effect evaluation of main symptoms, psychological evaluation before and after the treatment. The results showed that there was significant difference on the integral before and after treatment in both groups (P< 0.01). The posttreatment integral showed that the acupuncture with Chinese medicine group was better than the drug group (P<0.01). There was no significant difference on total effective rate between two groups. However, comparison on good improvement rate showed that the acupuncture with Chinese medicine group was better than the drug group (χ2 =28.25, P < 0.01). It was concluded that the acupuncture with Chinese medicine group had better effect on the im-provement of clinical symptom integral, psychological integral, and comprehensive effect evaluation. SJ acupuncture combined with HD powder was a safe treatment method with good effect.

Aim To investigate the effects of paclitaxel(PTX) on the expression of CD69, CD25 and proliferation of T cells by polyclonal stimulas in vitro, and explore the molecular mechanism of paclitaxel. Methods Fluorescence conjugated monoclonal antibodies and flow cytometry were used to detect the express of CD69 and CD25 by activated T cells in vitro in response to Concanavalin(Con A) and Phorbol 12,13-dibutyrate(PDB) or T cell proliferation index stained by CFDA-SE in response to PDB+Ion or Con A. Results Paclitaxel had no effect on the expression of CD69, but inhibited the expression of CD25 in activated T cells in response to Con A or PDB in a concentration-dependent manner. Paclitaxel caused a dose-dependent suppression of T cell proliferation to Con A as well as to PDB+Ion. Whether added at the beginning or after 24 h of stimulation by Con A or PDB+Ion, paclitaxel had identical effects. Conclusion The mid and later activation and proliferation of murine T cells stimulated by Con A or PDB+Ion were significantly inhibited by paclitaxel, suggesting that paclitaxel acts on the downstream signaling pathways of PKC?,and not act on the intitial activated associated proteins such as PTK and PKC?.

Objective: To explore the mechanisms of acupuncture in improving osteoporosis. Methods: In this study, the expression of OPG and BMP-2 proteins of femur in SAMP6 control group, SAMP6 acupuncture group, SAMP6 sham-acupuncture group and SAMR1 control group were determined by Western Blot technique. Results: Compared with SAMR1 control group, the expression of OPG and BMP-2 proteins of the femur in SAMP6 control mice decreased obviously. Acupuncture could stimulate the expression of OPG and BMP-2 and no differences were detected between the SAMR1 control group and SAMP6 acupuncture group. Conclusion: Osteoporosis observed in SAMP6 was correlated with low expression of OPG and BMP-2. After acupuncture treatment, both of them showed increased expression, it suggested that the curative effects of acupuncture on osteoporosis were partly due to stimulating skeleton formation, inducing the production of some local factors of bone metabolism and decreasing the bone turnover rate.

Objective To investigate the effects of siRNA targeting decoy receptor 3 on the cell proliferation of ovarian carcinoma cell CAOV3. Methods We constructed siRNA targeting decoy receptor 3,which was transfected into ovarian carcinoma cells CAOV3 , and observed the effects of DcR3 siRNA on the cell proliferation of CAOV3 cell by MTT experiment. The experiment contained 3 groups, including the normal control group (CAOV3 cell was not transfected), the negative control group (CAOV3 cell was transfected with blank vector) and the experimental group (CAOV3 cell was transfected with DcR3 siRNA). The expression levels of DcR3 mRNA were detected by Real-time PCR. Results DcR3 siRNA recognized and degraded DcR3 mRNA in CAOV3 cells of the experimental group. DcR3 mRNA of the experimental group was significantly decreased. The proliferation of CAOV3 cell was significantly decreased by DcR3 siRNA comparing with the normal control group and negative control group (P < 0.01). Conclusion DcR3 siRNA can inhibit the proliferation of ovarian cancer cell line CAOV3 by recognized and degraded DcR3 mRNA.

Objective To study carbapenem-resistant genes in a Myroides odoratimimus strain and clinical therapy.Methods A strain of Myroides odoratimimus was isolated from nephrostomy drainage fluid of a patient with urinary tract infection in Xinhua Hospital in May 2013.MicroflexTM MALDI-TOF MS and 16S rDNA sequencing were performed for strain identification.Vitek-2 Compact combined with E-test method was used for antibiotic susceptibility test.Modified Hodge test and imipenem/imipenem-inhibitor (IP/IPI)E-test were performed for drug-resistant phenotype screening.Carbapenemase genes blaMUS-1,blaVIM-1,blaVIM-2,blaIMP-1,blaIMP-2,blaNDM-1,blaOXA-48 and blaGESwere amplified by PCR,and the positive products were sequenced and analyzed.Results The isolated strain was identified as Myroides odoratimimus.The strain was resistant to 17 antibacterial agents,and the minimum inhibitory concentration (MIC) of imipenem was ≥ 16 μg/mL,while it was sensitive to minocycline (MIC =0.38 μg/mL) and intermediate to meropenem (MIC =6 μg/mL).It was negative in modified Hodge test but positive in IP/IPI E-test (IP/IPI≥ 8).blaMUS-1 gene was detected by PCR,and further confirmed by sequencing.Meropenem combined with minocycline was effective for the patient.Conclusion Carbapenem-resistance in this Myroides odoratimimus strain may be related to blaMUS-1 gene,and appropriate therapy for its infection should be based on the result of antibiotic susceptibility test.

Purpose:To evaluate the efficacy, toxicity and side effects of the combination of gemcitabine and cisplatin in the treatment of patients with non small cell lung cancer(NSCLC).Methods:35 patients with NSCLC diagnosed by pathology or cytology were enrolled into the study. The patients received gemcitabine 1 000 mg/m 2 on d 1,8 and 15 and cisplatin 80 mg/m 2 on d 1 of 28 day cycle (4 week regiment), or received gemcitabine 1 200 mg/m 2 on d 1,8 and cisplain 80 mg/m 2 on d 8 of the 21 day cycle (3 week regiment). Results:28 of all the cases could be evaluated. The total response rate was 53.6% (all of them were partial response). Response rate of 4 week regiment and 3 week regiment were 58.3% and 50.0%, there was no significant difference between the two groups. The major toxicity and side effects included leucopenia and thromasthenia, but they were acceptable. Conclusions:The combination of gemcitabine and cisplatin is an effective and tolerable regiment in the treatment of NSCLC. Further study on the efficacy, toxicity and side effects in the treatment of NSCLC with different regimens should be carried out in the future.

BACKGROUND:Neural stem cells have self-renewal and multidirectional differentiation potential, but under normal circumstances, the number of neural stem cells is less, and most cells are in the resting state. Thus, to promote the proliferation of neural stem cells is the key to the treatment of neurodegenerative diseases. OBJECTIVE:To investigate the effects of osthole on the proliferation of neural stem cells cultured in vitro, and to analyze its mechanism underlying promoting the proliferation. METHODS:Neural stem cells were cultured in vitro, and passage 3 cells were cultured with different concentrations of osthole(10, 50 and 100μmol/L). After 24 hours, cellvitality was determined by cellcounting kit-8. After 3, 5, 7 days of further culture, the radius of neurospheres was measured, and Ki67-positive cells were counted by immunofluorescence staining. Meanwhile, after 3 days of further culture, the gene expression of Notch 1, Hes 1 and Mash 1 in neural stem cells was detected by RT-PCR. RESULTS AND CONCLUSION:Compared with the control group, 50, 100μmol/L osthole could obviously promote the proliferation ability of neural stem cells. 100μmol/L osthole had the most significant effect and increased the expression of Notch 1 gene, Hes 1 gene, but it had no effect on Mash 1 gene. These results suggest that osthole can promote proliferation of neural stem cells cultured in vitro and its mechanism may be associated with activation of Notch 1 gene and Hes 1 gene in Notch signaling pathway.

Objective To study the effects of one finger massage on sciatic nerve injury rats. Methods The sciatic nerves were exposed, and the sciatic nerve was held by micro needles to make the sciatic nerve injury model. SD rats were randomly divided into sham-operation group, model group and massage group. In the sham-operation group, the sciatic nerves were exposed but not held. 7 d after the establishment of modeling, rats in massage group received one finger massage for 30 d. After 30 d, SFI and BBB of sciatic nerves were detected. HE staining, transmission electron microscope and immunochemistry assay were used to measure the changes of sciatic nerves. Results Compared with model group, massage group could speed up the recovery of SFI and increase BBB, promote the recovery of sciatic nerve morphology, increased protein level of S-100β, and enhance ultrastructure of newborn nerve growth and recovery. Conclusion One finger massage can effectively promote neurological and functional recovery after sciatic nerve injury in rats.

Objective To investigate the effects of osthole on neural stem cells ( NSCs) differentiation and explore the potential mechanism. Methods Brain-derived NSCs from newborn mice were isolated and cultured in vitro and determined by immunofluorescence. The P5 generations of NSCs were placed in culture solution with osthole at concentrations of (0,10,50, 100 μmol·L-1 ) . The neuron, astrocyte and oligodendroglia cell differentiation were determined by immunofluorescence. The mRNA expression of Notch 1 and its target genes Mash 1 and Neurogenin 2 were assessed by RT-PCR. Results The neurosphere displayed Nestin and Sox 2-postive by immunofluorescence, suggesting that the cultured cells were NSCs. Osthole promoted NSCs differentiating into more neuron(P<0. 01) and oligodendrocyte(P<0. 05), but not astrocyte. Meanwhile, osthole significantly reduced the mRNA expression of Notch 1(P<0. 01) and increased Ngn 2(P<0. 01)at the dose of 100 μmol·L-1. Conclusion Osthole enhances NSCs differentiating into more neuron and oligodendrocyte via probablly inhibiting Notch signal pathway.
