Objective To observe and investigate the effects of the case-based learning assisted with WeChat software in the teaching of nursing constitution regulating theory. Method The two classes of nursing undergraduate Grade 2013 were randomized into the case-based learning (CBL) group and the traditional teaching group (LBL). WeChat group combined with CBL group made preparation before class, including teachers writing the cases and thinking questions, WeChat sending teaching information, students discussing problems in group and collecting information. In class, students gave presentation and made speech, and the teachers made comments, did summary and gave scores to students' performance. In LBL group teacher prepared a lesson, and taught lessens assisted by multimedia PPT. After class, we used the test of nursing constitution regulating and teaching effect questionnaire to compare the differences between the two groups, using SPSS 21.0 for data statistics, and t test for measurement data. Results The single choice score, multiple choice score and the total score of the test of nursing constitution regulating in the CBL group were (52.46±4.35), (33.42±3.11), and (85.88±5.72), higher than the LBL group which were (47.63±5.84), (29.88±4.55), and (77.50±7.88). The difference was statistically significant. Scores of self-study ability, interest in learning, literature retrieval ability, communication and cooperation ability, TCM differentiation and the examination scores in CBL group were significantly higher than that in LBL group. Conclusion The case-based learning assisted with WeChat software can inspire the interest of learning, cultivate the self-study ability and practice the ability of TCM differentiation. It is worthy of being generalized.

Objective:To observe the change of CD4+CD25+regulatory T cells and Th17 cells in mice with experimental anti-phospholipid antibody syndrome ( EAPS ) .Methods: EAPS model was established by immunizing BALB/c mice with recombinant humanβ2 glycoprotein 1 (rhβ2GP1).The levels of serum anti-β2 glycoprotein 1 (anti-β2GP1),anti-cardiolipin antibody (aCA),IL-17,IL-2,IL-6 and TGF-βwere tested by ELISA.The rate of abortion,activated partial thromboplastin time (APTT) and platelet count were also detected.Flow cytometry was applied to detect the percentages of the CD4+CD25+regulatory T cells and Th17 cells in peripheral blood mononuclear cells.Results:Compared with the control group,the levels of anti-β2 GP1,aCA,IL-17,IL-2 and IL-6 were significantly increased,the rate of abortion was increased,APTT time was prolonged and the levels of TGF-βand platelet count were de-creased in model mice (P<0.05).No significant difference was detected of percentage of Treg cells in PBMC at the eighth weeks in model group (P>0.05),but percentage of Treg cells was lower than that in control group after 12 weeks (P<0.05);the percentage of Th17 cells in model group was higher than that in control group (P<0.05).In addition,the ratio of Treg/Th17 cells was lower in model mice than that in control group.Conclusion: The imbalance of CD4+CD25 Treg/Th17 cells may participate in the pathogenesis of EAPS.

To alleviate the shortage of excellent talents of traditional Chinese medicine (TCM), the State Administration of Traditional Chinese Medicine has decided to cultivate a group of talents with strong theoretical foundation, rich practical experience and exquisite skills who would like to devote themselves to TCM technology research. The national talent training program for inheritance of characteristic TCM technology is a major breakthrough in the history of new China in the cultivation of high-level TCM technology talents. A retrospective analysis was performed on the national talent training program for inheritance of characteristic TCM technology hold in training bases from Beijing, Shanghai, Guangdong Province, Jiangsu Province, Anhui Province, Xinjiang Uygur Autonomous Region, Inner Mongolia Autonomous Region, Heilongjiang Province, Yunnan Province, Sichuan Province, Shaanxi Province and Fujian Province. Based on the completion assessment work of 2014 and 2015 national talent training program for inheritance of characteristic TCM technology, and after knowledge exchange and discussion with the training subjects from 30 provinces and some teaching experts in the field of characteristic TCM technology, this paper summarizes the work of the national talent training program for inheritance of characteristic TCM technology. After trained in bases in China, training subjects' theoretical knowledge and practical skills as well as their comprehensive capacity have been greatly promoted. At the same time, there are also some problems and shortages. For example, characteristic TCM technology in some training bases is not prominent enough, some characteristic TCM technologies are not well inherited, and the affiliations of some training subjects do not pay enough attention to it. All of these problems should be solved and improved in future work.

BACKGROUNDTo evaluate the efficacy and safety of homemade human rh-endostatin (YH-16) combined with NP regimen (vinorelbine+cisplatin) for stage IIIB-IV non small cell lung cancer (NSCLC), and to compare with NP regimen alone.

METHODSEighteen NSCLC patients were divided into two groups. Group A ( n =9) received YH-16 combined with NP plan. Group B ( n =9) received NP regimen. They were treated with 2 or 3 cycles of chemotherapy. The overall response, time to progression (TTP), quality of life (QOL) and safety were observed.

RESULTSThe overall response was 22.2% in group A, and 0% in group B ( P > 0.05). The clinical benefit rate was 100% in group A, and 44.4% in group B ( P < 0.05). There was no significant relationship between response and clinical pathological characteristics of patients ( P > 0.05). The TTP was 178.8±70.8 days in group A and 85.4±48.2 days in group B ( P < 0.05). The main toxicities of the two groups were hematological toxicities, nausea and vomiting. No significant difference in incidence of toxicity was observed between the two groups ( P > 0.05).

CONCLUSIONSThe rh-endostatin combined with NP regimen for NSCLC tends to show a better chemotherapeutic effect and less toxicity than NP regimen alone. It is worthy of extensive clinical trial.

BACKGROUNDTo evaluate the activity and toxicity of paclitaxel as second-line treatment for advanced non-small cell lung cancer (NSCLC).

METHODSForty patients with recurrent advanced NSCLC were enrolled. Thirty-six patients were managed with regular regimen. Paclitaxel 135 mg/m², 3 h, on day 1; DDP 75 mg/m² or carboplatin 300-350 mg/m² on day 2. Four patients were managed with weekly regimen. Paclitaxel 60 mg/m²,3 h, on days 1,8,15; DDP 75 mg/m² on day 2. It was repeated every three or four weeks, up to two to four cycles.

RESULTSThirty-six cases were evaluated for response and 27 for survival. The objective response rate was 13.9% (5/36). At least one tumor-related symptom relief was observed in 21 patients (58.3%). The median survival duration was 26.4 weeks and 1-year survival rate was 8% (4/36). The main toxicities included myelosuppression, fatigue and myalgia-arthralgia neuropathy.

CONCLUSIONSPaclitaxel has advantage to be well-tolerated and improve tumor-related symptom. Further studies with standardization of dose and regimen will be needed to clarify its role in the second-line treatment.

Objective To investigate the role of cathepsin B(CTSB)inhuman cervical cancer HeLa cellswith Brucella infections.Methods The ctsb knockout(KO)HeLa cell line was constructed using CRISPR/Cas9.The effects of ctsbKO on cell proliferation and survival of intracellular bacteria in case of Brucella infection were detected by CCK-8 assay and intracellular bacteria count while the molecular mechanism of ctsb regulation on Brucella infection was revealed by Western blotting.Results The ctsbKO cell line was constructed.CCK-8 results showed that KO of ctsb had no impact on cell proliferationwith or without Brucella infection.The results of intracellular bacteria count showed a significant decrease in intracellular Brucella four days after infection in the KO cell line.Western blotting assay suggested that the expression levels of autophagy-related proteins were significantly down-regulated in the KO cell line with long-term Brucella infection.Conclusion KO of ctsb inhibits the intracellular survival of Brucella in long-term infections,providing a potential target for the treatment of chronic brucellosis.

BACKGROUNDUroacitides is a group of cell differentiation inducers, which is purified from fresh human urine. Preclinical studies of Uroacitides have showed that cancer cells could be induced to differentiate, and the growth of cancer cells could be inhibited by Uroacitides. The aim of this study is to compare the efficacy and toxicity between Uroacitides combined with NP regimen and NP alone in treatment of advanced non-small cell lung cancer (NSCLC).

METHODSForty-two cases of advanced NSCLC were randomized into Uroacitides+NP and NP groups. NP group: NVB 25mg/m² on days 1 and 8, DDP 75mg/m² on day 1. Uroacitides combined with NP group: Uroacitides of 300mL was given through subclavian catheter daily for 7 days prior to the NP chemotherapy, then concurrently with NP regimen for 2 cycles, except the days of administration of chemotherapy.

RESULTSIn the Uroacitides+NP group, the overall response rate was 44.4%, and 20.0% in the NP group (P > 0.05). The median survival time was 9 months in the Uroacitides+NP group and 6 months in the NP group (P=0.0287). The main toxicities were myelosuppression, gastrointestinal reaction and alopecia, and there was no significant difference in incidences of toxicities between the two groups (P > 0.05).

CONCLUSIONSUroacitides combined with NP regimen shows a good curative effect and low toxicity, and may significantly prolong the median survival time for advanced NSCLC.

BACKGROUNDTo evaluate the efficacy, side-effects, median survival duration and survival rate of vinorelbine (NVB) combined with cisplatin (DDP) in the treatment of non-small cell lung cancer (NSCLC).

METHODSA total of 220 patients with inoperable NSCLC received NVB and DDP combined chemotherapy: NVB 25-30 mg/(m²*d) on days 1 and 5 (or 8), DDP 60-80 mg/(m²*d) on day 2. The schedule was repeated every 28 days. The efficacy and side-effects were analysed and followed-up after at least two cycles of chemotherapy.

RESULTSThe overall response rate (CR+PR) was 30.9% (68/220). The response rate was 31.3% (51/163) in initial treatment group, and 29.8% (17/57) in retreatment group. The median survival duration was 8.3 months. The 1-, 2- and 3-year survival rates were 39.23%, 19.31% and 6.32%, respectively. The main side-effects were myelosuppression and digestive tract reactions.

CONCLUSIONSVinorelbine plus cisplatin is an effective and well-tolerated regimen for non small cell lung cancer and myelosuppression is its dose-limiting toxicity.
