China Journal of Chinese Materia Medica 2015;40(6):1212-1218
In the situation of global completion, collaborative innovation is becoming increasingly important because its advantage in risk avoiding and innovation efficiency. In order to explore the model of collaborative innovation and its evolution in traditional Chinese medicine of China, the cooperation in traditional Chinese medicine patents of China from 1985 to 2013 has been analyzed by using the method of scientometrics and social network analysis. It is proved that, though the number of grated cooperative patents has increased sharply during the last thirty years, the degree of cooperation innovation in traditional Chinese medicine of China is still not high. Moreover, in spite of the individual subject' s leading role in the past domestic collaborative innovation in traditional Chinese medicine of China, the institutions have been more and more powerful and achieved great improvement. At last, core institutions, represented by universities have played an important role in the collaborative innovation of domestic institutions, because they are key links between many institutions and promote the transferring and diffusion of knowledge.

To investigate whether accelerated blood clearance (ABC) phenomenon could be induced after repeated injection of mitoxantrone thermosensitive liposomes, LC-MS/MS and enzyme linked immunosorbent assay (ELISA) were used to measure the concentration of mitoxantrone and the anti-polyethylene glycol (PEG) IgM levels in rat plasma, separately. The drug was rapidly cleared away after the second administration. The anti-PEG IgM was detected after the first dose which was neutralized quickly after the second dose. It is proved that repeated administration of mitoxantrone thermosensitive liposomes in rat caused the ABC phenomenon.

OBJECTIVETo observe the inhibitory effect of gefitineb on the proliferation and its inducing effect on the apoptosis of mouse I-10 Leydig testicular cancer cells in vitro.
METHODSWe treated I-10 Leydig testicular cancer cells of mice with gefitineb at 0, 1.25, 2.5, 5, 10, 20, and 40 µmol/L. Then we determined the inhibitory effect of gefitineb on the growth of the cells by MTT, detected their early and late apoptosis by Annexin V-FITC/propidium iodide double staining and Hoechst 33258 nuclear staining, respectively, and observed the expressions of apoptosis-related proteins Bcl-2, Bax and caspase 3/9 by Western blot.
RESULTSCompared with the blank control group, gefitineb significantly inhibited the proliferation of the I-10 cells at 10 and 20 µmol/L (P < 0.05). The survival rate of the cells was (32.4 ± 2.8)% (P < 0.01) and their early and late apoptosis rates were (26.7 ± 4.2)% and (59.33 ± 10.2)% in the 40 µmol/L group, significantly different from those in the control (P < 0.05 and P <0.01). In comparison with the blank control group, gefitineb at 10, 20, and 40 µmol/L increased the expression of pro-apoptotic protein Bax by (41.9 ± 7.1), (60.1 ± 9.8), and (69.0 ± 11.3)% (all P < 0.05), decreased that of apoptosis-inhibitory protein Bcl-2 by (50.3 ± 8.9), (63.9 ± 6.9), and (88.7 ± 13.9)% (all P < 0.05), and elevated that of the cleft proteins caspase-3 by (69.0 ± 6.9)% (P < 0.05), (71.5 ± 8.1)% (P < 0.05), and (110.9 ± 14.2)% (P < 0.01) and caspase-9 by (51.8 ± 4.9), (54.7 ± 6.7), and (43.8 ± 11.8)% (all P < 0.05).
CONCLUSIONGefitineb can increase the cytotoxicity of I-10 Leydig testicular cancer cells of mice and induce their apoptosis via the mitochondria-mediated apoptosis signaling pathway.

BACKGROUND: Patients with acute stroke mostly receive treatment in the integrative hospital, but quite a large part of them were treated only with medication during the earlier stage.OBJECTIVE: To probe the influence of earlier integrative rehabilitations on emotions and daily life capability of patients with acute stroke with the outcomes compared with those unexposed to rehabilitative treatment.DESIGN: Randomized controlled study.SETTING: Neurological Department of a municipal Hospital.PARTICIPANTS: Eighty patients who received treatment due to the first onset of acute stroke of internal carotid system were selected from the Neurological Department of the First People's Hospital of Lianyungang City, Jiangshu Province between January 2002 and August 2003. Totally 51 males and 29 females aged (63.42±7.47) years were randomly divided into rehabilitation control group with 40 cases each.METHODS: Patients of the two groups received routine neurological medication in the hospital. When stroke was controlled, patients in the rehabilitative group (including patients with cerebral infarction who were hospitalized for less than 1 week and patients with cerebral hemorrhage who were hospitalized for less than 2 weeks) were subjected to rehabilitative treatment, including rehabilitative training of insulted limbs (physical treatment and/or exercise therapy), physical therapy, acupuncture and psychological consultation. Rehabilitative treatment was given 1-2 times a day and 45 minutes for each time. Physical therapy and acupuncture were given once a day and 20 minutes for each time. In contrast, patients in the control group were only asked in the doctor's round to do exercise themselves or with the assistance of others. Psychological states of all the patients were assessed with Symptom Self Rating Scale before treatment and discharge and daily life capability was also assessed with Barthel index (totally 10 items with scores of 0-15, full mark was 100, and patients who scored for < 60were considered of self-incapability).MAIN OUTCOME MEASURES: Scores for symptom checklist (SCL)and Barthel index of the two groups before treatment and when patients were discharged.Scores for each symptom factors in SCL were significantly improved in the rehabilitation group when patients were discharged from the hospital (P < 0.05-0.01), and somatization, obsessive-compulsive, depression, anxiety and psychoticism, etc. were also obviously improved in the control group (P < 0.05); moreover scores for somatization, obsessive-compulsive,depression, anxiety phobic anxiety and psychoticism in the rehabilitation group after treatment were significantly lower than those in the control group [(1.55±0.43), (1.80±0.35); (1.48±0.39), (1.68±0.55); (1.54±0.43),(1.83±0.37); (1.32±0.39), (1.56±0.36); (1.46±0.43), (1.66±0.52); (1.12±0.38),creased aftertreatment (P < 0.05-0.01), but those of the rehabilitation group were significantly higher than those of the control group [(73.24±4.64),(52.44±2.86), P < 0.05].CONCLUSION:Scores for symptomatic factors in SCL and Barthel indexes were improved after treatment, especially in patients who received rehabilitative treatment, suggesting that earlier integrative rehabilitative treatment may play active influence on the emotions and daily life capability of patients following acute stroke.

Objective The aim of our study is to investigate the prevalence of Carbapenem-resistant Klebsiella pneumoniae (CRKP) and the genetic characteristics of the class 1 integron in CRKP on multi-drug resistance.Methods Clinical Klebsiella pneumoniae strains were collected from multiple departments of a hospital in central China. CRKP strains were identified among the isolates, and antibiotics susceptibility of CRKP strains was analyzed. The polymerase chain reaction (PCR) was adopted to amplify the class 1 integron variable area. The integron genetic structure was analyzed with enzyme digestion and DNA sequencing technology. The relation between class 1 integron and drug resistance was analyzed statistically.Results Totally 955 strains of Klebsiella pneumoniae were isolated from varied sites of the hospital, and 117(12.3%) of them were identified as CRKP, with a separation rate of 8.9% (26/292) in 2013, 11.3% (38/336) in 2014 and 16.2% (53/327) in 2015, which shows an increasing trend by year. 44.4% (52/117) of CRKP strains were separated from specimen of ICU, and 61.5% (72/117) were from sputum. Over 95% CRKP strains were resistant to ampicillin/sulbactam, aztreonam, imipenem, meropenem, ceftazidme, cefotaxime, cefepime,and piperacillin, while relatively low resistant rates were found in tigecycline (12.8%) and colistin (35.9%). The class 1 integron was detected in 77.8% (91/117) of CRKP strains. Class 1 integron of CRKP was significantly correlated with the antibiotic resistance to the tobramycin, gentamicin and amikacin (all P<0.01). The gene cassette analysis of variable area of class 1 integron showed that aadA2 accounts for 64.8% (59/91), aacA4-catB8-aadA1 23.1% (21/91), and aadA2-dfrA25 12.1% (11/91).Conclusions CRKP has an increasing trend in a clinical setting in China, and most of them were resistant to multiple antibiotics. Class 1 integron in CRKP has strong ability to capture the genes resistant to aminoglycosides antibiotics from environment, with the aadA2 gene as the most popular one.
