Objective To explore the prognostic factor by analyzing clinical characters, pathologic features and treatment methods of thymic carcinoma. Methods From January 2000 to Deceber 2011, 71 patients received re-section of thymic carcinoma. They were analyzed retrospectively based on Masaoka stage(stageII 7,stageIII 33, stageIV 31). The clinical factors included histological classification, Masaoka stage, treatment and prognosis. Sur-vival rate was calculated and the survival curve was plotted by Kaplan-Meimer and Log-Rank method, Multi-analy-sis was carried out by COX regression. Results For these patients, the median survival time was 57. 2 months, the 5-year survival rate was 47. 9%. 25 patients received complete resection with 5-years survival rate 68%, 46 patients received partial resection with 5-years survival rate 36. 9%. 41 patients whose lump size was greater than or equal to 8 cm with 5-years survival rate 53. 6%, 40% with lower than 8 cm. Histology Masaoka staging with 5-years survival rate was stage II(57. 1%) , stage III(69. 7%) and stage IV(29. 0%) , respectively. Defferent his-tological type with 5-years survival rate squamous carcinoma(55. 1%) , adenocarcinoma (14. 3%) ,small cell car-cinoma ( 28. 6%) , adenosquamous carcinoma ( 33. 3%) , and carcinoid ( 100%) , respectively. The operation method, the maximum diameter, mass Masaoka stage and different pathology types for survival were statistically dif-ferent (P<0. 05). Preoperative treatment, postoperative radiotherapy and differentiation degree of survival had no statistical difference. Conclusion Surgical method, lump size, masaoka stage and histological type are the impor-tant factors affecting prognosis. Adjuvant radiotherapy maybe is not the poor prognosis factor of thymic tumors. Sur-gical method and lump size are the significant independent prognostic factors in patients with thymic tumors.

Objective To observe the clinical efficacy of electroacupuncture plus moxibustion in treating infantile cerebral palsy. Method Eighty eligible patients with infantile cerebral palsy were randomized into a treatment group of 42 cases and a control group of 38 cases. The control group was intervened by physiotherapy (PT), while the treatment group was given electroacupuncture at scalp acupoints, body acupuncture, and moxibustion along the Governor Vessel in addition to the treatment given to the control group. The two groups were treated once a day, 6 months in total. The comprehensive ability and the Gross Motor Function Measure (GMFM) were evaluated before and after the interventions in the two groups, and the clinical efficacies were compared.Result After 6-month treatment, the total effective rate was 92.9% in the treatment group versus 78.9% in the control group, and the total effective rate of the treatment group was superior to that of the control group (P<0.05). The motor function and activities of daily living were significantly improved in both groups after the interventions (P<0.05,P<0.01); after the treatment, there were significant differences in comparing the motor function and activities of daily living between the two groups (P<0.05). The GMFM scores of each domain were significantly changed after the treatment in both groups (P<0.05); after the treatment, there were significant differences in comparing the GMFM scores of each domain between the two groups (P<0.05).Conclusion Compared with being used alone, conventional PT can more significantly benefit the improvement of motor function of cerebral palsy patients when electroacupuncture and moxibustion were added.

Objective: To investigate the effects of dexmedetomidine (DEX) on oxidative stress and systemic inflammatory response syndrome(SIRS) during cardiopulmonary bypass (CPB).Methods: Totally 62 patients scheduled for mitral valve replacement surgery were enrolled in this study and randomly assigned to DEX group with constant infusion of DEX (0.5 μg·kg-1 ·h-1 , n =31) and the control group with the same amount of 0.9% sodium chloride injection(n =31).A volume of 4 ml of jugular vein blood was respectively withdrawn before the induction of anesthesia (T0), at 10 min after aortic-off clamping(T1), the end of bypass(T2), 4h after bypass(T3),12h after bypass(T4) and 24h after bypass(T5).The serum C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6(IL-6), interleukin-8(IL-8) and interleukin-10(IL-10) were determined.Results: The serum CRP in both groups increased remarkably at T1-T5 , while the serum CRP in DEX group was significantly lower than those in the control group at T3-T5.The serum TNF-α increased remarkably in control group at T2-T4, while the serum TNF-α increased remarkably in DEX group at T2-T3;the serum TNF-α in DEX group was significantly lower than those in the control group at T3-T4.The serum IL-6, IL-8, IL-10 in both groups were increased remarkably at T2-T5, T1-T5,T1-T3, respectively.The serum IL-6 and IL-8 in the DEX group were significantly lower than those in the control group at T2-T4 while the serum IL-10 in the DEX group was significantly higher than that in the control group at T1-T3.The serum WBC in both groups at T3-T5 were higher than those at T0, while the serum WBC in the control group was significantly higher than that in the DEX group at T3-T5.However, the differences between the two groups at mechanical ventilation time, ICU observation time, the incidence of postoperative SIRS after 24h, hospitalization days, and the adverse reactions were not statistically significant.Conclusion: DEX has notable protective effects on systemic inflammatory response syndrome during extracorporeal circulation.

AIM: To evaluate the effect of binocular visual function training in pediatric ocular trauma. METHODS: There were 76 patients (76 eyes) that were hospitalized with a primary diagnosis of ocular injury at the Affiliated Hospital of Medical College, Qingdao University between January 2006 and December 2009. Binocular visual function training was given after primary wound repair. Far stereopsis function were checked using AIT-1000 synoptophore fusion, and near stereopsis function was checked using Titmus stereogram.Binocular visual function was compared before and after training. RESULTS: Before binocular visual function training,26 eyes（34%）had no binocular vision, after training there were only 16 eyes（21%） without binocular vision. Before undertaking binocular visual function training with fusion, only 27 eyes (36%) had binocular vision, after the training there were 48 eyes (63%) with binocular vision. Before undertaking binocular visual function training with far stereopsis ,there were 23 eyes (30%) with binocular vision, after the training there were 29 eyes (38%). Before binocular visual function training with near stereopsis, there were 14 eyes (18%) with binocular vision, after the training there were 33 eyes (43%) with binocular vision. There was a significant difference in the number of patients with binocular vision before and after binocular visual function training. CONCLUSION:The training is useful for the reconstruction of binocular visual function in pediatric ocular trauma.

Objective To study the different expressions of receptor activator of nuclear factor-kappa B ligang(RANKL) mRNA in spleens of rats fed with diet of low calcium and high fluoride. Methods A 2× 2×2 factorial design was used and the factors were calcium, fluoride and action time. In the design, 40 Wistar rats [average body mass(118.9±13.5)g] were divided into four groups randomly by weight: control with normal diet (0.790%, calcium), low calcium group with low calcium intake(0.063%, calcium), high fluoride group with normal diet and high fluoride intake(100 mg/L, fluoride) and low calcium and high fluoride group with low calcium and high fluoride intake. After 4 and 8 months, 5 rats of each group were sacrificed and total RNA was extracted from spleen. And the expression levels of RANKL mRNA were determined by reverse transcription polymerase chain reaction (RT-PCR). Results At time of 4 months, the expression level of RANKL mRNA was 0.13± 0.05,0.13± 0.03,0.17±0.02,0.27± 0.05 and at time of 8 months, it was 0.11 ± 0.01,0.16 ± 0.02,0.16± 0.03,0.36 ± 0.07 in control group, low calcium group, high fluoride group, low calcium with high fluoride group, repectively. The factorial design AVONA showed that low calcium and high fluoride had significant effects on RANKL mRNA expression(F = 40.224,56.679, all P < 0.05) while action time had not(F = 2.850, P > 0.05 ). The interactions of low calcium with high fluoride or high fluoride with action time were signifieant(F = 7.247, 18.789, all P < 0.05) while the interaction of high fluoride with action time was not(F = 1.751, P > 0.05). Conclusions Low calcium alone or high fluoride alone or low calcium with high fluoride or low calcium with action time can increase the the RANKL mRNA expression level. High fluoride does not affect the RANKL mRNA level as the action time is prolonged.

Objective To investigate the effect of analgesia with dezocine on CD4+ and CD8+ T lymphocytes in patients after pulmonary lobectomy.Methods Seveuty patients with early non-small-cell lung cancer were selected,and they were scheduled the pulmonary lobectomy.The patients were divided into control group and dezocine group by random digits table method with 35 cases each.The patients in dezocine group were given 0.5 mg/ml dezocine by patient-controlled analgesia (PCA) pump,and the patients in control group were given 0.9％ sodium chloride by PCA pump.The peripheral blood lymphocytes count and percentages of CD4+ T lymphocytes,CD8+ T lymphocytes,natural killer cell (NK cell) before anesthesia induction and 4,24,48 h after operation were detected.Results In control group,the peripheral blood lymphocytes count and NK cell 24 h after operation were (1.08 ± 0.21) × 109/L and 0.141 4 ± 0.021 8,which before anesthesia induction were (1.71 ± 0.33) × 109/L and 0.190 9 ± 0.022 8,and there were statistical differences (P ＜ 0.05).In dezocine group,the peripheral blood lymphocytes count and NK cell 24 h after operation were (1.14 ±0.28) × 109/L and 0.124 9 ± 0.027 6,which before anesthesia induction were (1.69 ± 0.28) × 109/L and 0.198 6 ± 0.027 5,and there were statistical differences (P ＜ 0.05).The CD4+ T lymphocytes 24 h after operation in dezocine group was significantly higher than that in control group (0.355 6 ±0.031 1 vs.0.273 5 ±0.029 4),and there was statistical difference (P ＜0.05).There was no statistical difference in CD8+ T lymphocytes between the 2 groups (P ＞ 0.05).Conclusion Analgesia with dezocine can notably improve immunosuppression in patients after pulmonary lobectomy.

The strain Acidiphilium cryptum DX1-1 producing PHB was irradiated respectively by UV and Co60 to raise PHB production. The results indicated that the effect of UV better than using Co60. One strain of the UV mutagenized called UV60-3 has the highest PHB production yield, showing final PHB concentra- tion of 28.56 g/L, 1.45 times higher than that of original strain. FT-IR spectroscopy analysis shows that the polymers obtained from the strain DX1-1 have the same IR spectra of standard PHB. Further research about the best appropriate C/N ratio of the mutant was done. The optimum ratio of C/N was about 3.76, the final PHB concentration reaches to 30.57 g/L.

OBJECTIVETo observe the effects of polydatin on learning and memory and cyclin-dependent kinase 5 (Cdk5) kinase activity in the hippocampus of rats with chronic alcoholism.

METHODSForty rats were randomly divided into 4 groups: control group, chronic alcoholism group, low and high polydatin group. The rat chronic alcoholism model was established by ethanol 3.0 g/(kg · d) (intragastric administration). The abstinence scoring was used to evaluate the rats withdrawal symptoms; cognitive function was measured by Morris water maze experiment; Cdk5 protein expression in the hippocampus was detected by immunofluorescence; Cdk5 kinase activity in the hippocampus was detected by liquid scintillation counting method.

RESULTSThe abstinence score, escape latency, Cdk5 kinase activity in chronic alcoholism group rats were significantly higher than those of control group (P < 0.05). The abstinence score, escape latency in high polydatin group rats were significantly lower than those of chronic alcoholism group (P < 0.05); Cdk5 kinase activity in high and low polydatin group rats was significantly lower than that of chronic alcoholism group( P < 0.05); immunofluorescence showed that the Cdk5 positive cells of chronic alcoholism group were significantly increased compared with control group (P < 0.05), and the Cdk5 positive cells of polydatin groups were significantly decreased compared with chronic alcoholism group ( P < 0.05).

CONCLUSIONPolydatin-reduced the chronic alcoholism damage may interrelate with regulation of Cdk5 kinase activity.

BACKGROUNDThe aim of this research was to explore quality of life (QOL) and acceptance of disability and social support of colostomy patients as well as the relationship between these factors.

METHODSA descriptive, correlational study was conducted using four scales: the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and European Organization for Research and Treatment of Cancer Colorectal Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-CR38) scales, the Acceptance of Disability Scale (ADS), and the Social Relational Quality Scale (SRQS). A convenience sample of 111 colostomy patients from four hospitals in Guangzhou who underwent colostomy operation at least one month prior to the study and who visited the stoma clinic or association from August 2011 to February 2012 was evaluated for inclusion in the study. All statistical analyses were performed using SPSS 17.0 software (SPSS Inc., Chicago, IL, USA).

RESULTSThe patients' general health status was better than the reference level recommended by European Organization for Research and Treatment of Cancer, and the overall ADS score was average. The SRQS score was similar to that found in a Hong Kong study. The general health status and dimensions of QOL were significantly correlated with ADS and all of its dimensions (P < 0.05). The general health status and dimensions of QOL were also significantly correlated with SRQS and all of its dimensions (P < 0.05).

CONCLUSIONSQOL, acceptance of disability, and social relational quality of colostomy patients were closely related. Our results emphasize that patients should work to form rational values and close bonds with families and friends to achieve a better QOL.
