Methods The screening programme targeted colorectal cancer in old people was conducted on 1 100 participants aged 60-92 years (mean was 81.3 years). All subjects received OC-Hemodia and COB examinations. Positive subjects were examined by colonoscopy and/or barium enema. Out of 1 100 subjects 1 046 were followed up in the next five years. Results Among 1 100 subjects, 231 subjects (21.0%) were positive by OC-Hemodia test and 159 subjects (14.5%) were positive by COB. There was a significant difference in positive rate between OC-Hemodia test and COB (P

Objective: To seek the optimal acupuncture time for primary dysmenorrhea and provide clinical basis for optimal acupuncture treatment protocol. Methods:A total of 90 eligible cases were randomly allocated into three groups, 30 cases in each group. Points Guanyuan (CV 4), bilateral Zusanli (ST 36) and Sanyinjiao (SP 6) were selected for patients in all three groups, with a different treatment duration: 15 min in group A, 30 min in group B and 45 min in group C. Then the clinical efficacy in each group was evaluated by pain symptom scoring. Results:As for the pain symptom scores, there were statistically significant intra-group differences between before and after treatment in three groups (allP<0.05); coupled with statistically significant inter-group differences between group B and the other two groups (bothP<0.05). As for clinical efficacy, there were statistical differences between group B and the other two groups (bothP<0.05), indicating that 30 min of acupuncture is the optimal duration in the treatment of dysmenorrhea. Conclusion:With the same needling manipulation, 30 min of acupuncture treatment achieves a better efficacy for primary dysmenorrhea.

Objective To observe effects of ganoderma lucidum triterpenoids(GLT) on learning and memory function and anti-oxidative ability of aging model mice induced by D-galactose. Methods Senile model mice were established by D-galactose hypodermic injection for 8 weeks.GLT had been administered to two therapy groups.All the mice of different groups were tested with Morris water maze.Then the mice were killed and biochemically assayed of total anti-oxidative capacity(T-AOC),superoxide dismutase(SOD) and malondialdehyde(MDA) in the brain. Results The model mice showed worse ability in learning and memory in comparison with control mice.The T-AOC activity and SOD activity in the brain decreased and the MDA content increased in model rats in comparison with control.GLT significantly improved the changes mentioned above. Conclusion GLT improved the learning and memory dysfunction in aging model mice by modulation of the anti-oxidative ability.

Photothermal therapy (PTT) has attracted significant attention due to minimal side effects and high treatment specificity. However, it often requires very high temperature to achieve complete tumor ablation under a single PTT. Such high temperature brings obvious thermal damage and inflammatory response to the body, affecting the therapeutic effect. In recent years, nitric oxide (NO) has been used to significantly inhibit tumor growth and enhance the sensitivity of tumor cells of temperature and drugs, thus enhancing the therapeutic effect. However, compounds as NO donors often have some disadvantages such as poor biocompatibility and untargeted delivery, etc., therefore, this medical application based on NO therapy is limited. In conclusion, the organic combination of NO donors and photothermal agents (PTAs) is expected to overcome the shortcomings of single therapy and achieve the antitumor effect of "1 + 1 > 2". In view of the rapid development of NO combining with PTT in tumor therapy, this review firstly introduces the antitumor mechanisms of different types of NO donors. Then the treatment strategy based on NO combined with PTT is discussed. Finally, the prospects and challenges of this combination therapy strategy in the clinical treatment of cancer are discussed.

AIM: To investigate the alterations of tear film after sutureless large incision manual cataract extraction (SLIMCE). METHODS: Sixty-eight SLIMCE operation eyes were studied with slit-limp microscope, break- up time (BUT), SchirmmerⅠtest (SⅠt),and fluorescence(FL) to observe the alterations of tear film at different time points in postoperation. Impression cytology and microphoto-analyses technique were also applied to observe the goblet cells at different time points postoperation(7,14,30,60,90 days). RESULTS: Subjective complaint of dry eye within 90 days after the operations were significantly increased compare with preoperations(5-27,23,19,16,13; 2-16,14,8,6,3). The schirmmer Ⅰ test were greatly increased in 14 days postoperation(10.1±4.5;15.0±4.7,13.8±5.7),the mean scores of fluorescence increased (0-17,9,5;0-8,3,1) and the mean break-up time decreased in 30 days post-operation(10.3±2.2;5.5±2.3,7.0±2.4,7.9±2.2) (P<0.05). CONCLUSION: SLIMCE operation have effect on the stability of tear film.

Objective:To evaluate the validity and reliability of the Chinese version of the Eating Disorder Examination Questionnaire 6.0 (EDE-Q 6.0) in female patients with eating disorders.Methods:A total of 239 patients with eating disorder and 142 healthy controls who were recruited consented to participate in the study and completed Chinese EDE-Q 6.0.Confirmatory factor analysis was used in patients to compare the original 4-factor model,1-factor model and 3-factor model.The criterion validity was tested with the Eating Disorder Inventory (EDI).Mann-Whitney U analysis was used to compare the differences of EDE-Q 6.0 scores on the two samples to test the empirical validity,and ROC analysis was used to determine the cut-off value.The internal consistency of the scale was tested in two samples.Among all participants,89 patients and 31 healthy controls were retested 1 month later.Results:The original 4-factor model fit better than the other two.The EDE-Q 6.0 total score and the EDI total score had a high consistency in the total sample,patients and controls,respectively (ICC =0.88,0.87,0.73).Patients had higher scores on the EDE-Q 6.0 than controls (Ps ＜0.01).The mean area under the curve (AUC) of EDE-Q 6.0 was 0.91,the optimal cut-off point of EDE-Q 6.0 was total score ≥ 1.27,sensitivity and specificity were 79.4％ and 88.2％ respectively.The Cronbach α coefficients were 0.95,0.91,and 0.88 for the total sample,patients and controls respectively.The test-retest reliabilities were 0.73 for the total scale,0.58,0.68,0.69 and 0.71 for the 4 factors.Conclusion:The Chinese version of the Eating Disorder Examination Questionnaire 6.0 have good psychometric properties and diagnosis accuracy,and it could be used to assess the severity of clinical symptoms.

OBJECTIVETo investigate the result of hip arthroplasty for failed internal fixation of femoral neck fractures.

METHODSFrom June 2007 to January 2014, 29 cases who underwent hip arthroplasty for failed of internal fixation of femoral neck fractures were reviewed. There were 12 males and 17 females. The mean age was 60.3 years (ranged 43 to 83 years) at the time of the fracture. Left hip was in 16 cases, right hip was in 13 cases. The average interval from fracture to arthroplasty was 23.3 months (ranged, 3 to 48 months).

RESULTSAll of 29 cases were performed total hip arthroplasty. There were 20 cases of cementless cup,7 cases of cementless cup with bone graft, 2 cases of cemented cup with bone graft; 13 cases of cementless stem, 16 cases of cemented stem. There were no complications occurred such as intraoperative fracture of the greater trochanter. The average operative time was (115 ± 38) minutes,the mean intraoperative blood loss was (420 ± 175) ml, the average postoperative drainage volume (240 ± 119) ml, intraoperative blood transfusion was (200 ± 220) ml, intraoperative fluid volume was (2,200 ± 400) ml, the average postoperative blood transfusion was (300 ± 200) ml. There was 1 case get postoperative dislocation. All patients were followed up for 14.7 months in average (ranged, 5 to 24 months). There was no revision for mechanical failure. Harris Hip Score significantly was improved from 51.1 ± 7.5 before the conversion to 88.5 ± 6.4 points at the final follow-up.

CONCLUSIONThe effect of the hip replacement for patients with failed internal fixation of femoral neck fractures was confirmed. This method can shorten the time on the bed and reduce the complications. It benefits the patients earlier functional recovery, but it must control operation indication. The long term efficacy is necessary to further observation.

Objective To identify the risk factors of delirium in ICU by Meta-analysis. Methods Quality of the studies was assessed in terms of study design, definitions of main variables, statistics, and bias control. Analysis of sensitivity and heterogeneity were performed and cumulative effects were calculated using either fixed or random effects models by RevMan 4.2.Results Ten studies met all inclusive and exclusive criteria. Simple sizes range from 100 to 3308. Twenty-one risk factors of delirium in ICU were involved, but only alcohol abuse, respiratory disease, infection, APACHE Ⅱ,elevated level of serum urea nitrogen, hyponatremia, hyperbilirubinemia and using sedatives were identified as having a cumulative effect on delirium in ICU. Conclusions Infection, abnormality or disturbance of metabolism and intoxication or acute withdrawal from drug or alcohol are independent predictors of delirium in ICU, while advanced age and hypoxemia, which are commonly considered as independent risk factors of delirium in ICU, are still inconclusive.
