Objective To investigate the change of serum CD62p of coronary heart disease (CHD) patients after different doses of clopidogrel administration.Methods One hundred and ninety-one patients with CHD were selected as our subjects.Of which,95 cases were with SAP and 66 cases were with non ST segment elevation acute coronary syndrome (NST-ACS).SAP patients were randomly given clopidogrel at dose of 75 mg/d or 150 mg/d and served as A and B groups.NST-ACS patients were randomly given 300 mg clopidogrel,then randomly divided into C and D groups with sequentially taking clopidogrel at dose of 75 mg/d or 150 mg/d respectively.Thirty healthy peoples were served as E group without drug intervention.Concentrations of serum CD62p were detected by Elisa before taking clopidogrel,24 h and the fifty day of after taking clopidogrel.Results (1) Before taking clopidogrel,the serum concentrations of CD62p in CHD patients were higher (A group:(7.62 ± 2.99) ng/L,B group:(8.48 ± 3.13) ng/L,C group:(9.50 ± 3.32) ng/L,D group:(10.22 ± 5.14) ng/L than that of healthy control group ((5.49 ± 1.99) ng/L,P ＜ 0.05).The Serum CD62p levels in SAP patients were lower than that of NST-ACS patients (P ＜ 0.05).(2)The serum concentrations of CD62p in A and B groups at before taking clopidogrel were (7.62 ±2.99) ng/L and (8.48 ±3.13) ng/L respectively,higher than that four days after taking clopidogrel ((6.79 ± 2.51) ng/L,(6.37 ± 1.80) ng/L;t =2.390,4.520;P ＜0.05 or P ＜0.01).There was no statistical significant difference between A and B groups(P ＞0.05).(3) In C and D groups,the serum CD62p at before taking clopidogrel were (9.50 ±3.32) ng/L and (10.22 ±5.14) ng/L,higher than that after taking clopidogrel for four days ((8.21 ± 2.62) ng/L,(8.17 ± 2.37) ng/L; t =2.084,2.157 ; P ＜ 0.05).No significant difference was seen between C and D groups (P ＞ 0.05).Conclusion The serum CD62p in patients with CHD was higher than that in the healthy control.Clopidogrel administration can decrease serum CD62p in CHD patients.

Polysaccharides are important large molecules in the body. It has many functions such as activting the lymphocytes like T,B, NK and M? cells, promoting the secretion of cytokines and antibodies through binding to the CR 3 receptor of lymphocytes, affecting the concentrations of cellar [Ca 2+ ] i, cAMP, cGMP, NO and PGE 2, and promoting the gene expression of cytokines. Its function also relate to its molecule weight and structure.

Objective To compare the effects of nonsurgical spinal decompression system (SDS) cervical traction and common cervical traction using surface electromyography (sEMG).Methods Twenty-two volunteers' sEMG signals were recorded before,during and after two modes of cervical traction:the conventional traction in sitting and SDS traction in supine.The interval between the two modes of traction was no shorter than 24 hours.The mean and peak amplitudes of their sEMG signals were observed before,during and after traction.The sEMG signals of the posterior cervical muscle while sitting or lying were compared at different stages of the traction.Results There was no statistically significant difference in sEMG signals between the subjects' right and left posterior cervical muscles.The sEMG signals decreased significantly during both traction trials.With common cervical traction the mean and peak amplitudes of the left posterior cervical muscle pre-and post-traction were higher than during traction,and the same as that of the right posterior cervical muscle.In the SDS trials the sEMG signals during traction and post-traction were significantly lower than those pre-traction.After traction the sEMG signals while sitting (common cervical traction) were significantly higher than those post-traction while lying (SDS cervical traction),and the sEMG signals post-traction while either lying or sitting were stronger than during traction while lying.The post-traction signals in sitting were stronger than those in lying.Conclusions Both nonsurgical SDS and common cervical traction can relax the posterior cervical muscles.The effect of nonsurgical SDS was better than that of common cervical traction.

Objective To study military medical graduates' psychological elastic characteris-tics and the key influencing factors. Methods A comparative study of 817 graduate students and 597 undergraduate students in a military academy was conducted by using positive negative emotions, pos-itive and negative cognitive bias and Mental Resilience Scale. Independent sample t-test, single factor analysis of variance, correlation analysis, and step-wise regression analysis were conducted by SPSS 18.0 for data analysis. Results ①Resilience scores of postgraduate students were significantly lower than those of undergraduate students (76.01 ±11.43 vs. 80.00 ±10.26, t=-6.76, P<0.01). Resilience scores of military postgraduates were significantly higher than those of local postgraduates (77.18 ± 11.59 vs. 74.97±11.19, t=2.77, P<0.05). Resilience scores of female postgraduates were significantly lower than those of males (74.79 ±10.83 vs. 76.94 ±11.78, t=2.68, P<0.05), reflected in factors of tenacity and strength. ②Resilience and its factors were positively related to positive affect and atten-tion to positive information (r=0.448~0.625, P<0.01), while negatively related to negative affect and attention to negative information (r=-0.206~-0.448, P<0.01). ③Regression analysis showed that posi-tive and negative emotion, attention to positive and negative information can significantly predict re-silience, accounting for the variance of 53.7%. ④Positive and negative affect partially mediated the relationship between attention to positive information and positive affect and resilience. Conclusion Attention to positive information and positive affect may be potential targets for intervention to enhance the level of resilience among military medical postgraduate students.

OBJECTIVE: To observe the clinical effect of perforated bovine amnion combined with recombinant bovine basic fibroblast growth factor (rb-bFGF) on degree Ⅱ burn wounds.METHODS: A total of 43 patients with small and medium-size thermal burn were collected, and the area of testing wound was 1% -2%. The wounds with the same nature were divided into three groups: perforated bovine amnion (treatment group), bovine amnion (control 1 group), and vaseline gauze dressing (control 2 group). All the three groups combined with rb-bFGF. RESULTS: Compared with control 1 group (P < 0.01) and control 2 group (P < 0.05), the treatment group could obviously decrease the healing time of deep degree Ⅱ burn wounds. For superficial degree Ⅱ burn wounds, compared with the control 2 group, the treatment group could also decrease the healing time; however, there was no significant difference between treatment group and control 1 group (P > 0.05). Dressing was not changed frequently, and the pain was relieved. Rash or other adverse effects were not detected in the three groups.CONCLUSION: The combination of perforated bovine amnion and rb-bFGF can obviously promote the healing of burn wounds.

Objective: To study the clinical effect of video-assisted thoracoscopic surgery in the treatment of early non-small cell lung cancer(NSCLC). Methods: 130 cases with early NSCLC were selected.According to random number table, the patients were divided into the observation group and the control group, 65 cases in each group.The observation group was treated with video-assisted thoracoscopic surgery, while the control group was treated with thoracotomy.The perioperative period of the two groups was compared, 24h before operation and 24h after operation, the changes of T lymphocyte subsets(CD₃⁺ , CD₄⁺ , CD₄⁺ /CD₈⁺ ) were measured, and the postoperative complications were recorded.The patients were followed up for one year, the survival rate and recurrence rate were recorded. Results: There was no statistically significant difference in the number of lymph node dissection between the two groups(t=1.023, P>0.05). The operation time of the observation group was significantly longer than that of the control group(t=6.479, P<0.05), the amount of bleeding of the observation group was significantly less than that of the control group, the postoperative drainage time and ambulation time of the observation group were significantly shorter than those of the control group, the pain score of the observation group was lower than that of the control group, the differences were statistically significant(t=17.081, 16.040, 39.443, 21.237, all P<0.05). After operation, the CD₃⁺ , CD₄⁺ , CD₄⁺ /CD₈⁺ in the two groups were significantly reduced compared with before operation(observation group: t=5.591, 5.300, 4.300; the control group: t=10.450, 10.735, 4.883, all P<0.05), the CD₃⁺ , CD₄⁺ , CD₄⁺ /CD₈⁺ of the observation group were significantly higher than those of the control group[(58.95±7.58)% vs.(52.42±7.52)%, (34.83±3.75)% vs.(30.07±3.12)%, (1.21±0.17) vs.(1.15±0.13), t=4.931, 7.867, 2.260, all P<0.05]. The incidence rate of complications of the observation group was significantly lower than that of the control group[6.15%(4/65) vs.18.46%(12/65), χ²=4.561, P<0.05]. The patients were followed up for 1 year, there were no statistically significant differences in survival and recurrence between the two groups(χ²=0.367, 0.208, all P>0.05). Conclusion Video-assisted thoracoscopic surgery is well for early NSCLC patients, with advantages of small trauma, quick recovery, and it can help to protect the immune function of the organism, the clinical value is high.
