We analyzed the surveillance data of measles from January 1999 to October 2000 in Jiangxi Province for the aim of measles control. The results showed that 3*!184 measles cases were reported from the province and 1 reported case died. Most of the reported measles cases were under 15 years old. The incidence of measles in age group between 7-10 years old was higher than that in other age groups and most of the reported cases having vaccination histroy were 4-10 year old children. Both the sporadic and epidemic measles in some districts existed at the same time and the reported measles cases extensively distributed in all districts of Jiangxi Province. The outbreaks of measles in some districts had affected the morbidity of measles of the whole province To prevent and control measles outbreak are the main effective measures to control this disease.

Objective:To test the effects and differences of gratitude,indebtedness and happiness on people's helping behaviors. Methods:Totally 190 college students from 3 classes in Henan Province were selected. Three sit-uational experiments of gratitude,indebtedness and happiness were used to inspire participants'mood according-ly. Each class randomized to receive a situational experiment,the altruism subscales of Philosophies of Human Na-ture(PHN),the assessment tool of helping others and helping others voluntarily were used to measure the college students'altruistic idea,helping others and helping behavior voluntarily,and the methods of descriptive statistics,co-variance analysis and regression analysis was adopted. Results:In helping others and helping others voluntarily,ac-cording to the results of covariance analysis,the effect of covariate altruistic ideas was significant [F(1,186)=9. 24,10. 52;Ps<0. 01],and the main effect of emotional state was also significant[F(2,186)=3. 50,3. 45;Ps<0. 05 ]. The scores of helping others and helping others voluntarily were higher in the gratitude group than in the happiness group[(4. 21 ±0. 10)vs. (3. 86 ±0. 09),(4. 22 ±0. 09)vs. (3. 90 ±0. 08)]. Regression analysis showed that gratitude could positively predict helping others and helping others voluntarily(β=0. 33,0. 20),and happiness could positively predict helping others voluntarily(β=0. 16). Conclusion:Excluding the effect of altruism idea to helping others and helping others voluntarily,the effects of emotional state to helping others and helping others vol-untarily are all significant. It suggests that participants under the state of gratitude could show more helping others and helping others voluntarily than participants under happiness,that is to say,comparing with happiness,gratitude may be more conducive to the cultivation of helping behavior.

Objective: To examine the expression of glucocorticoid receptor in human colon cancinoma tis-sues and call lines and to explore the survival of colon cancer cell lines treated with dexamethasone alone or in combination with 5-Fu and L-OHP in a way of dexamethasone pretreatment or co-administration in vitro.Methods: The expression of glucocorticoid receptor was detected in 61 cases of colon cancer tissue samples and 4 types of colon cancer cell lines by immunohistochemistry. Apoptosis was detected by Hoechst33342 staining and flow cytometry. MTT assay was employed to detect the chemosensitivity of colon carcinoma cells to L-OHP and 5-Fu with dexamethasone pretreatment for 24 hours or co-administretion. Results: Positive GR expression was found in 57.3% colon cancer tissue samples and in Lovo and HCT-116 cell lines, not in HT-29 and SW-480. Apoptosis was detected in GR-expressed Lovo and HCT-116 cells at 72 hours after 1×10~(-4)mol/L Dex treatment, and the rates of apoptosis were higher than those in the control groups without Dex (P<0.01),GR-negative cells, HT-29 and SW-480 even treated with 1 × 10~(-4)mol/L Dex for 72 hours. Pretreatment and co-administration for Lovo cells with 1×10~(-4)mol/L Dex could decrease the IC50 of L-OHP from 13.7±1:1.3μg/mL to 5.9±0.6μg/mL and 4.8±0.7μg/mL, respectively. IC50 of 5-Fu was decreased from 72.2±8.1 μg/mL to 21.1±4.1μg/mL and 18.6±4.0μg/mL, respectively. Conclusion: There is expression of glucocorticoid receptor in part of colon carcinoma tissue samples and cell lines. Apoptosis does occur in GR-expressed Lovo and HCT-116 cells induced by dexamethasone in vitro. Pretreatment for 24h and co-administration with Dex can increase the chemosensitivity of Lovo cells to L-OHP and 5-Fu.

Objective To observe the efficacy and safety of intravitreal injection of ranibizumab in the treatment of retinopathy of prematurity (ROP).Methods Data from 49 consecutive ROP patients (95 eyes) including type Ⅰ pre-threshold,threshold and aggressive posterior ROP who had received anti-VEGF treatment for the first time in our hospital from June 2014 to August 2015 were collected.60 eyes from the 95 eyes were confined as the zone Ⅰ disease group,while the remaining 35 eyes as zone Ⅱ disease group.The difference of birth weight,gestational age,corrected gestational age,treatment effects,recurrence and re-treatment time between two groups were compared.0.025 mL ranibizumab (10 mg · mL-1) was injected through 1.5 mm puncture after corneal limbus by using 30G 1 mL injection syringe.At the end of the injection,tobramycin and dexamethasone ophthalmic ointment eye bag was used.After the injection of 3 days,the portable slit lamp and tonometer were used to observe the intraocular pressure,intraocular hemorrhage and endophthalmitis.The indirect ophthalmoscope was used to observe the retinal vascular tortuosity and ridge regression of lesion expansion at 1 week after treatment.At the same time,the systemic adverse reactions related to treatment were observed.Results After receiving ranibizumab treatment for the first time,93 eyes (95.9％) exhibited ROP regression after single injection,including 58 eyes in zone Ⅰ disease group,35 eyes in zone Ⅱ disease group.There was no statistical difference between two groups (P ＞ 0.05).22 eyes required additional anti-VEGF injection or laser treatment for ROP recurrence,including 17 eyes in zone Ⅰ disease group,5 eyes in zone Ⅱ disease group.There was statistical difference between two groups (P ＜0.05).The time from recurrence to re-treatment was (6.50 ±2.54) weeks,which in zone Ⅰ disease group was (6.44 ± 2.74) weeks and in zone Ⅱ disease group was (6.67 ± 2.31)weeks,there was no statistical difference between two groups (P ＞ 0.05).No local or systemic adverse events associated with the treatment or drug was observed within the following period.Conclusion Intravitreal injection of ranibizumab is an effective and well tolerated method for zone Ⅰ and zone Ⅱ ROP,but the recurrence rate is high.There Is no local or systemic adverse events associated with the treatment or drug.

OBJECTIVE To established a viable and convenient method for human nasoseptal chondrocyte culture in vitro and study the biological characters of the chondrocyte. METHODS The chondrocytes were obtained by incomplete enzyme digestion of cartilage and were seeded with small piece of cartilage in 25 ml culture flasks coated with polylysine previously. This study determines the biologic synthesis of the chondrocytes by toluidine blue and type Ⅱcollagen immunohistochemistry reaction. The proteoglycan synthesis efficiencies of human nasoseptal chondrocytes cultured in vitro were measured by using 35S-Na2SO4 incorporation. The modified method and the conventional method in proteoglycan synthesis were also compared. RESULTS The results suggested that human nasoseptal chondrocytes cultured by modified method still show the normal structure and morphology, and maintain the function of metabolism and self duplication. With the modified method, we can get a higher cell survival rate and more cells. CONCLUSION The modified method is a viable and convenient method.

Objective:To observe the influences of functions of chemokine receptor 9(CCR9) on leukemia patients,we analyzed 38 typical T cell lymphocytic leukemia cases.Methods:The functions of T ALL and T CLL CD4+T cells towards TECK/CCL25 were determined by chemotaxis assay and adhesion assay.Results:Almost in all of the T ALL patients,TECK/CCL25(a ligand for CCR9)could induce a high chemotactic migration of T ALL CD4+ cells as well as a high adhesion.Conclusion:It indicates that CCR9 and its ligands may promote survival or proliferation of T ALL cells.

Objective To investigate the application value of combination of thinprep cytologic test (TCT),human papilloma virus (HPV),c-MYC and human chromosome telomerase gene (hTERC) genes to screen cervical cancer.Methods A total of 230 cases of the study objects was detected with TCT and HP,respectively.Amplification of c-MYC and hTERC genes was tested with fluorescence in situ hybridization (FISH) method.The histopathological results were the gold standard,and the sensitivity,specificity and accuracy of cervical intraepithelial neoplasia (CIN) Ⅱ / Ⅲ and squamous cell carcinoma (SCC) were compared with the four combined detection.Results Of 230 screened patients,there were 124 cases of TCT positive,155 cases of HPV positive,c-MYC gene amplified in 118 cases,and hTERC gene amplified in 128 cases.When TCT,HPV,c-MYC,and hTERC were used alone,the highest sensitivity was HPV (84.5％),the highest specificity was c-MYC (97.6％),and the highest accuracy was hTERC (85.2％).When the three indexes were used in coordination with each other,the sensitivity and accuracy of TCT + HPV + hTERC were the highest (98.6％ and 90.9％),and the specificity of TCT + c-MYC + hTERC was the highest (79.3％).When the four indexes were used together,the sensitivity was 98.6％,the specificity was 72.0％,and the accuracy was 89.1％.Conclusions Combined examination can improve the sensitivity and accuracy of screening cervical lesions,and the three combination of TCT + HPV + hTERC had the best effect,and c-MYC gene detection had the highest specificity.

Objective: To investigate the picky eating behavior among school-age children and to analyze its association with their health status, providing scientific basis for health promotion of school-age children in China. Methods: A total of 796 students of grade 3 to grade 6 from two primary schools in Hongshan, Wuhan were selected through cluster sampling. Statistical analysis was conducted according to the results of the 3-day food record and questionnaire survey on children and their caregivers. Results: In the current study, 40.58% of the children had picky eating problems, the incidence of picky eating behaviors of migrant children was higher than that of local children(χ2=3.92, P<0.05). Most of the picky eaters(23.87%) tended to reject vegetables. Compared to the others, picky eaters had lower intake of vitamin B 2 [(0.49±0.01)(0.46±0.01)mg] and vitamin C [(57.35±0.76)(54.32±0.90)mg] (t=2.03, 2.57, P<0.05) and had a higher risk of stunting(OR=1.42, P<0.05). Conclusion Picky eating behaviors are common among school-age children, which is significantly associated with stunting. Nutritional education for children (especially migrant children) are urgently needed to improve their dietary structure and promote healthy growth and development.

Objectives:To design a self-control training program based on the recent findings of self-control and self-regulation after taking full consideration of the unique characteristics of depression disorder,with an emphasis on behavioral activation and reinforcement.Methods:Totally 46 students who were diagnosed with major depression were randomly assigned to one of the two groups:Group 1 (n =23),and Group 2 (n =23).Participants in the Group 1 received 24-week self-control training program,as compared to Group 2 who received only baseline and post-24-week-intervention measurements,the measurements included Self-control Scale (SCS) and Beck Depression Inventory (BDI-Ⅱ).The self-control training included eight-week training modules and 16-week consolidation module.Results:In Group 1,the SCS scores were higher in post-intervention than in baseline measurement [(38.0 ± 6.3) vs.(34.7 ± 8.2),P ＜ 0.01],and the BDI-Ⅱ scores were lower in post-intervention than in baseline measurement [(19.0 ± 6.1) vs.(21.8 ± 4.8),P＜0.01] in Group 1.Whereas in Group 2,there were no significant differences between baseline and post-24-week-intervention measurements of SCS and BDI-Ⅱ scores (Ps ＞0.05).Conclusion:The study provides new evidence for the self-regulation model of depression.Self-control training could be an effective intervention strategy for the treatment of depression.

Objective: To analyze the relationship between single nucleotide polymorphisms (SNP) of Notch signaling pathway and susceptibility to lung cancer. Methods: The present study was a hospital-based case-control study. All 1 121 patients of lung cancer diagnosed by histopathology three hospitals in Fujian and Nanjing were selected as cases from January 2006 to December 2012. At the same time, 1 121 healthy population from other departments of the hospital to visit patients or community, excluding those with tumor, chronic disease, and immediate family members of lung cancer, were enrolled in control group. A uniform questionnaire was used to collect general information. Matrix-assisted laster desorption ionization time of flight mass spectrometry (MALDI-TOF-MS) was used to identify the polymorphisms of 9 SNP (Notch3 rs3815188, Notch4 rs915894, Notch4 rs520692, DLL1 rs1033583, JAG1 rs8708, JAG2 rs9972231, HEY1 rs1046472, HEY2 rs3734637, HES2 rs11364) in 1 121 lung cancer patients and 1 121 healthy controls. The association between SNP and lung cancer was analyzed by χ² and logistic regression model. Results: The average age of cases and controls was (58.70±10.73) and (58.98±10.85) years old. The OR for genotype AC carriers of HEY1 rs1046472 was 0.80 (95%CI: 0.66-0.97) when comparing with genotype CC. The OR for genotype AC+AA carriers of HEY1 rs1046472 was 0.81 (95% CI: 0.67-0.98) when comparing with genotype CC. The OR for genotype AC carriers of HEY2 rs3734637 was 0.82 (95%CI: 0.67-0.99) when comparing with genotype AA.
