OBJECTIVE:To explore the potential correlation between clinical efficacy of pemetrexed in the treatment of ad-vanced breast cancer and TS mRNA expression. METHODS:Patients with advanced breast cancer were recruited in our study. Three cycles of pemetrexed was given to these patients,TS mRNA expression of their tumor tissues were detected. The relationship of ther-apeutic efficacies of different chemotherapy with TS mRNA expression were observed and compared during the study period. RE-SULTS:58 patients received pemetrexed chemotherapy and therapeutic efficacies of them were evaluated. One patient (1.7%) had complete response,19 patients(32.8%)had partial response,31 patients(53.4%)had stable response and 7 patients(12.1%)has progressive disease. Objective response rate was 34.5%,and disease control rate was 87.9%. TS mRNA expression level of 55 pa-tients with completed TS mRNA expression analysis varied from 0.04 to 5.11,with a median of 0.62. Mann-Whitney rank test showed that,responders had lower TS mRNA expression than nonsponders at all visits,there was statistical significance (P<0.05). Chi-square test showed that patients with low expression level of baseline(before chemotherapy)TS mRNA had significantly higher objective response rate(63.3%)than those with high expression(36.7%),there was statistical significance(P<0.05). CON-CLUSIONS:TS mRNA expression level is related to therapeutic efficacy of pemetrexed,which may be useful for predicting thera-peutic efficacy of pemetrexed therapy in patients with advanced breast cancer.

Objective To evaluate the efficacy and safety of short-term sensor-augmented insulin-pump (SAP) therapy for poorly controlled patients with type 1 diabetes mellitus (T1DM).Methods Sixty T1DM patients with glycosylated hemoglobin (HbA1c)>9.0% were randomly assigned to 2 groups treated with SAP or multiple daily insulin injection ( MDI) for 6 days, then all patients converted to MDI therapy. Results Compared with MDI group and before therapy, the mean blood glucose concentration ( MBG) , SD of blood glucose, mean amplitude of glycemic excursion ( MAGE) and 24-h area under curve at 10.0 ( AUC10.0 ) levels in SAP group significantly decreased after 6-day therapy ( compared with MDI group:t=1.761,P=0.028, t=2.569,P=0.037, t=2.712,P=0.020, t=2.985,P=0.014, compared with before therapy:t=3.128,P=0.006, t=2.689,P=0.024, t=2.966,P=0.013, t=3.076,P=0.009);while there was no difference in 24-h area under curve at 3.9 (AUC3.9) between groups (P>0.05).After 1 month follow-up HbA1c levels decreased in SAP group (t=2.344,P=0.023) and were significantly lower than those in MDI group (t=1.844, P=0.035).There was no difference in daily insulin dosage, fasting C peptide (FCP) and postprandial 2h C peptide (2hCP) between two groups (P>0.05).Age (t=2.125, P=0.012) and SAP therapy (t=3.376, P=0.009) were independently correlated with the HbA1c after 1 month.Conclusion Short-term SAP therapy is effective and safe for poorly controlled T1DM patients with rapid glucose lowering and glycemic excursions reduction.

Objective To evaluate the role of gliocytes in the spinal cord in the development of inflammatory pain (IP) in rats. Methods Adult male SD rats weighing 180-220 g were used in this experiment. A catheter was implanted in the subarachnoid space according to the method described by Yang. Animals with abnormal motor function of the hindlimb after intrathecal (IT) catheter implantation were excluded. IP was induced by subcutaneous (sc) injection of complete Freund's adjuvant (CFA) 50 μl at the lateral side of the ankle joint of the right hindpaw. Sixty-five rats were randomly divided into 5 groups ( n = 13 each): group I IP control normal saline (NS) 50μl was injected sc instead of CFA; group II IP; group IE PC (IT) + IP control fluorinated citric acid (FC, a gliocyte metabolism inhibitor) 1 nmol/10μl was injected IT at 15 min before NS 50 μl sc injection; group IV NS (IT) + IP and group V FC (IT) + IP. The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured 2 d before induction of IP (T_0, baseline) .before and at 2, 4, 6, 8, 10, 12, 24 and 26 h (T_(1-9)) after sc NS or CFA injection. Five enimals in each group were killed at T_5 (8 h after sc NS/CFA injection) and the lumbar segment (L_(4,5)) was removed for determination of glial fibrillary acidic protein ( CFAP) and OX-42 expression by immuno-histochemistry. Results In group Ⅱ and Ⅳ sc CFA significantly decreased MWT and TWL. Mechanical and thermal hyperalgegia induced by sc CFA was significantly suppressed by intrathecal FC in group V . IP significantly increased GFAP and OX-42 expression in the spinal cord. Intrathecal FC significantly attenuated IP-induced up-regulation of GFAP and OX-42 expression in the spinal cord. Conclusion The activation of gliocytes in the spinal cord is involved in the development of CFA-induced hyperalgesia in rats.

Objective To investigate the impacts of phillyrin on exudates and lung injury in rats with acute pleurisy by regulating the NLRP3 inflammatory pathway.Methods Ninety rats were randomly divided into the control group,the model group,the low-dose phillyrin(PH-L,5 mg/kg)group,the medium-dose phillyrin(PH-M,10 mg/kg)group,the high-dose phillyrin(PH-H,20 mg/kg)group and the NLRP3 pathway inhibitor(PJ34,10 mg/kg)group.FVC,FEV 0.1 and FEV 0.3 were detected by lung function analyzer.Electronic balance was used to weigh the mass of chest exudate.The number of white blood cells in exudate was detected by Wright staining.Contents of prostaglandin E2(PGE2),monocyte chemoattractant protein-1(MCP-1),interleukin(IL)-6 and tumor necrosis factor-α(TNF-α)in exudate were detected by ELISA.Automatic blood gas analyzer was used to detect p(CO2)and p(O2)of rats.HE staining was used to observe pathological changes of lung tissue.The expression levels of NLRP3 and Caspase-1 protein were detected by immunohistochemistry.Western blot assay was used to detect the expression of NLRP3 pathway protein.Results Compared with the control group,the quality of pleural exudate and the number of white blood cells,the contents of PGE2,MCP-1,IL-6,TNF-α,the expression of p(CO2)and NLRP3 pathway proteins in exudate of the model group increased obviously,FVC,FEV 0.1,FEV 0.3 and p(O2)decreased obviously,and the lung tissue showed obvious pathological damage(P＜0.05).Compared with the model group,the quality of pleural exudate and the number of white blood cells,the contents of PGE2,MCP-1,IL-6,TNF-α,the expression of p(CO2),NLRP3 pathway proteins in the exudate of rats decreased obviously in the PH group and the PJ34 group,FVC,FEV 0.1,FEV 0.3 and p(O2)increased obviously,the pathological injury of lung tissue was obviously improved(P＜0.05).Compared with the PH-H group,there were no significant differences in the above indexes in the PJ34 group(P＞0.05).Conclusion PH can improve lung injury induced by acute pleurisy in rats by inhibiting the activation of NLRP3 pathway and inhibiting inflammatory reaction.

The aging of the population has led to a sharp increase in the demand of the elderly for long-term care services. How to ensure the quality of long-term care services is a hot topic of widespread concern in society. In developed countries, long-term care services have been carried out early, a perfect service quality evaluation system has been formed, and the evaluation results have been effectively used. Long-term care services in China started late, there is no unified evaluation standard for the quality of long-term care services, and the evaluation indicators are diversified. It is necessary to explore a long-term care service quality evaluation system with Chinese characteristics based on foreign experience, covering the whole process of long-term care services. In addition, core indicators need to be selected to reflect the quality of long-term care services, strengthen the application of evaluation results, improve the effectiveness of long-term care service quality evaluation, and promote the sustainable development of long-term care in China.

Objective:To explore the construction of evaluation criteria for long-term care ability of the elderly suitable for China's national conditions.Methods:The evaluation criteria were initially established through literature research and field semi-structured interviews. Through the Delphi method, 15 experts were consulted and the evaluation criteria for the long-term care ability of the elderly were finally established.Results:The effective rate of the two rounds of expert consultation questionnaires was 100%, and the expert authority coefficients were 0.91 and 0.92 respectively. The evaluation criteria for long-term care ability of the elderly were established, including two first-level indicators of self-care ability and disease severity, four second-level indicators of abilities of daily living, mental state and social participation, perception and communication, and disease severity, as well as 39 third-level indicators including recumbent status, cognitive function, level of consciousness, illness and so on.Conclusions:The evaluation criteria for long-term care ability of the elderly are scientific and reliable, which can provide a reference for the classification of long-term care services for the disabled elderly in China.

OBJECTIVETo explore the efficacy and prognostic factors of induction therapy combined with autogenetic peripheral blood stem cells transplantation (APBSCT)in patients with multiple myeloma (MM).

METHODSFrom January 1998 to May 2015, 201 patients with MM were enrolled. All patients received APBSCT after induction therapy. With the follow up to 20 June 2015, the overall survival (OS), progression free survival (PFS)and prognostic factor were analyzed.

RESULTS① With a media follow up of 36.67 months, the median PFS and OS were 22.87 (17.48- 28.26)and 69.63 (63.57- 75.69)months, 5-year PFS and OS were 17% and 49%, respectively. ②After APBSCT, when the subgroup (n= 112) achieved complete response (CR)compared with the subgroup (n=89) not achieved CR, the median PFS were 32.93 (21.03-44.83) and 18.13 (14.46-21.80) months (P<0.001), respectively; And the media OS were 96.77 (71.79- 121.75)and 54.70 (49.53- 59.87) months (P=0.004), respectively. The risks for disease progression and death declined in CR subgroup. ③ Two subgroups included or not included bortezomib/thalidomide at induction therapy (123 patientsvs 21 patients), the media PFS were 31.67 (24.36- 38.98)and 15.20 (10.11- 20.29) months (P=0.013), respectively; And the media OS were 76.30 (55.44- 97.15)and 52.03 (33.76- 70.30) months (P=0.014), respectively. ④According to the ISS stage, the media OS of stageⅠ, Ⅱ, Ⅲ were 99.47 (59.58-139.36), 66.77 (52.17-81.37), 53.97 (28.71-79.23) (P< 0.001), respectively. The risk for death of stage Ⅱ, Ⅲ were 2.16 and 3.04 times higher than stage Ⅰ, with no difference in terms of PFS. ⑤ The media PFS in IgD (n=22) and IgG (n=101) type MM were 11.17 (10.27- 13.13)and 35.43 (22.69- 48.17)months (P=0.007) , respectively; The media OS were 30.83 (0.24-61.42)and 70.70 (53.52-87.88) months (P=0.039), respectively. The risk for disease progression of IgD type was 2.47 times higher than IgG type. ⑥ Patients received 1 line induction therapy (n=132) compared with more than 1 line (n=69), the media PFS were 25.43 (16.09- 34.77)and 20.27 (15.04- 25.50) months (P=0.042). ⑦Cox analysis showed that CR after APBSCT and ISS stage were independent prognostic factors for OS. IgD type MM and CR after APBSCT were independent prognosis factor for PFS.

CONCLUSIONCR after APBSCT and ISS stage were independent prognostic factors for OS in MM. CR after APBSCT was independent prognostic factor for PFS in MM. However, disease progression more likely occurred in IgD type MM, which was independent negative prognostic factor for PFS in MM.
