Cancer Research and Clinic 2016;28(6):383-387
Objective To explore the value of diffusion-weighted imaging (DWI) on evaluation and prediction of therapeutic outcome in concurrent chemoradiotherapy for cervical squamous carcinoma.Methods 26 cases of cervical squamous carcinoma were examined by MRI before and one month after concurrent chemoradiotherapy.The patients were divided according to tumor response evaluated by Response Evaluation Criteria in Solid Tumors (RECIST).Apparent diffusion coefficient (ADC) values and the receiver operating characteristic (ROC) curve analysis were carried out before and one month after treatment.Results 26 cases had higher mean ADC one month after the concurrent chemoradiotherapy than that before treatment[(1.542±0.189) × 10-3 mm2/s vs (0.898±0.096) × 10-3 mm2/s,P < 0.05].After the treatment,there were 17cases of complete remission (CR) and 9 cases of partial remission (PR).ADC value in PR group was higher than that in CR group [(0.960±0.115) × 10-3 mm2/s vs (0.864±0.067) × 10-3 mm2/s,P < 0.05].ROC curve showed that with 0.927 × 10-3 mm2/s of ADC as threshold to determine the tumor remission,the sensitivity and specificity were 66.7 % and 76.5 %,respectively,and the area under the ROC curve was 0.752 (P < 0.05).At one month after treatment,the tumor volume was decreased in different degrees in CR group and PR group,and the differences of ADC had statistical significance between the two groups [(1.603±0.183) × 10-3 mm2/s vs(1.427±0.146) × 10-3 mm2/s,P< 0.05].ROC curve showed that with 1.444 × 10-3 mm2/s of ADC as a threshold for diagnosing tumor residual,the sensitivity and specificity were 76.5 % and 55.6 % respectively,and the area under the ROC curve was 0.765 (P < 0.05).Conclusions DWI as a useful supplement,can help to precisely evaluate the tumor response after the concurrent chemoradiotherapy and monitor the effects of the treatment.Besides,the ADC before chemoradiotherapy has the predictive value on short-term prognosis in cervical squamous cell carcinoma.

Eighty patients with T2DM hospitalized at Tongren Hospital, Beijing during June to December 2009 were chosen for survey by FFQ (food frequency questionnaire).Their daily food intake and nutrient intake were collected and percentage of energy generated from carbohydrate, protein and fat were estimated for each participant, and analyzed based on the criteria of dietary intake for T2DM, the dietary guidelines and the recommendations for dietary nutritional structure for Chinese residents.Among 80 patients with T2DM, 27 (34%) were found insufficient daily protein intake, 39 (49%) insufficient carbohydrates,40 (50%) excessive fat, and 74 (93%) insufficient dietary fiber, respectively.There was a significant gap between their daily total energy intake and that recommended for patients with T2DM ( P < 0.01 or 0.05 ).No significant difference was found in daily intake of total energy, protein, fat carbohydrate and dietary fiber among T2DM patients with varied body mass index ( P > 0.05 ).Dietary pattern and actions and selfmanagement in the patients with T2DM surveyed are not so reasonable.

Objective To investigate the effect of Zidan decoction containing serum on endometrial receptivity in uterine immunity environment,and then to discuss if it's effect on endometrial receptivity through its controlling the expression of cell factors which related to endometrial receptivity.Methods Mice's endometrium tissue samples and uterine Natural Killer (UNK) cells were obtained from pregnant mice on gd 4.5 days and gd 12.5 days.After endometrial glandular epithelial cells,endometrial stromal cells and UNK cells were separated through primary culture,epithelial cells and endometrial stromal cells at rate of 1 ∶ 1 a certain concentration UNK were mixed together and highly purified-cultured.Different concentrations of Zidan decoction was acted on the culture solution.FBS,black and aspirin control group were setup for contrast.The expression of LIF and VEGF which influenced by Zidan decoction in the immunity environment was assayed by Realtime-PCR.Results The expression of LIF and VEGF was significantly increased in the immunity environment of uterine (in 10% Zidan decoction group,10% aspirin group and 10% blank control group:LIF was 2.10±0.20,1.98±0.14,0.90±0.05 separately,and VEGF was 3.17±0.31,2.52±0.09,0.92±0.06respectively,P<0.05).Conclusion Zidan decoction could improve endometrial receptivity by increasing the expression of cell factor which related to endometrial receptivity with the help ofUNK paracrine.

Objective To analyze HIV/AIDS epidemic characteristics in Henan Province.Methods The database of HIV/AIDS cases information and follow-up information from the national online case reporting were downloaded.Comprehensive analysis was performed.Results 42 879 cases were confirmed and reported HIV positive,69.05% were former paid plasma donors at the end of 2008.Among these cases reported in 2008,26.64% were heterosexual transmission,and 49.59% (1 802) were found via voluntary counseling and testing.Conclusions The epidemic characteristics of HIV/AIDS in Henan Province was mainly among former paid plasma donors.But the transmission through plasma donor had been interdicted.While the proportion of sexual transmission was increasing,this suggested that education and behavior intervention should be strengthened in order to interrupt further transmission.Counseling and testing become main source of detecting HIV infection.

Medical students will be the clinicians in the future.The medical moral education and the moral character formation will directly influence their medical careers.It is extremely important for the medical students to know basic theory of the medical moral and develop their character by strengthening the medical moral and criterion education,especially in the time of increasing conflicts between doctors and patients.

OBJECTIVE:To probe into the characteristics and the general pattern of adverse drug reactions(ADRs)induced by ritodrine and relevant factors. METHODS:26 literatures according with ADR diagnosis standard were retrieved from CNKI from 1999 to 2009. A total of 337 ADR cases induced by ritodrine were analyzed statistically. RESULTS:The incidence of ritodorine-inducing ADRs was 29.96%(337/1 125). Several clinical manifestations appeared simultaneously. ADR of cardiovascular system accounted for 76.55%(n=284). 5.93% of patients with ADR stop taking medicine because of poor drug tolerance. CONCLUSION: Great importance should be attached to ADR monitoring,adjustment of administration route to guarantee the safety of drug use.

Objective To estimate the consistency between the diagnostic criteria for dermatomyositis (DM) and polymyositis (PM) developed by Bohan and Peter criteria (B/P criteria) and ENMC criteria.Methods The clinical,laboratory and pathological data from 86 patients who were initially diagnosed with idiopathic inflammatory myopathy were collected retrospectively.These patients were diagnosed according to B/P criteria and ENMC criteria,and the similarities and differences between these two criteria were compared.The data were analyzed with Mann Whitney U test and Kappa test by SPSS 13.0 software.Results Thirtyseven DM and 49 PM were diagnosed using B/P criteria.Forty-six DM and 14 PM were diagnosed using ENMC criteria,and 1 was diagnosed as eosinophilic myositis,9 were diagnosed as sporadic inclusion body myositis (sIBM),11 cases were diagnosed as limb-girdle muscular dystrophy type 2B,and the diagnosis of 5 patients could not be clarified.Agreement for DM between these two sets of criteria was very good by Kappa test (κ=0.79),but the corresponding between the two tests for PM was poor (κ=0.26).Conclusion Our study has demonstrated that B/P criteria may cause over-diagnosis and misdiagnosing for PM.ENMC criteria involves immunohistochemical pathology,stratified clinical and pathological exclusion criteria.The diagnostic accuracy of ENMC criteria is much improved.
