Objective To investigate knowledge of cervical cancer,human papillomavirus (HPV) and HPV vaccine and attitude to HPV vaccine among employed urban women in China,and to assess willingness to vaccinate their children.Methods This study was conducted in women from 16 factories or companies in Beijing,Hangzhou,Changsha,Chcngdu and Guangzhou.A questionnaire on cervical cancer,HPV knowledge and HPV vaccine acceptability was administered to participants before and after educational intervention.Results A total of 1 146 women were surveyed from August to November,2011.The awareness rates of cervical cancer,HPV and HPV vaccine were 95.06 ％,27.98 ％ and 12.82 ％,respectively.Only 20.68 ％ knew that HPV was related to cervical cancer.After educatioual instruction,89.26 ％ understood the relationship between HPV and cervical cancer (x2 =93.414,P ＜ 0.001).Only 19.25 ％ women were unwilling to allow their children to be vaccinated.The main reasons were as follows:worried about vaccine safety (23.52 ％),belief that their child was not at risk (21.92 ％),lack of scientific evidence for the vaccine (13.01％),and worricd about vaccine efficacy (12.79 ％).Conclusions In general,there is a high acceptability of HPV vaccine to prevent cervical cancer among employed urban Chinese women after educational intervention.However,some women remain reluctant to vaccinate their children due to concern about vaccine safety and efficacy.

Objective To observe the efficacy and adverse reaction of raltitrexed combined with irino-tecan as first-line chemotherapy for recurrent or metastatic gastric cancer.Methods From January 201 4 to March 201 5,39 patients of recurrent or metastatic gastric cancer who received treatment in the First People′s Hospital of Zhangjiagang of Jiangsu Province were collected.All patients received raltitrexed (3.0 mg/m2 , 1 5 min intravenous drip)on the first day and irinotecan (1 80.0 mg/m2 ,90 min intravenous drip)on the first day.One cycle lasted 21 days.The efficacies were evaluated every 2-cycle.Adverse reactions were evaluated every cycle.Results The efficacies and adverse reactions could be evaluated in 39 patients.The study received 0 complete remission,1 6 partial remission,1 1 stable disease,1 2 progression disease.The objective response rate was 41 .03% (1 6 /39).The disease control rate was 69.23% (27 /39).The median overall sur-vival time was 9.3 months (95%CI:8.8-1 1 .1 months).The median progression-free survival time was 6.0 months (95%CI:5.1 -6.8 months).The adverse reactions were mainly neutropenia,anemia,liver dysfunc-tion,the incidence of them were 35.90%,33.33% and 28.21 % respectively.Conlusion Raltitrexed com-bined with irinotecan as first-line chemotherapy for recurrent or metastatic gastric cancer acquires an definite efficacy,and the adverse reactions can be tolerated,which is worthy of further clinical research.

AIM: To re-identify the special motif regulating osteoclast(OC)differentiation in receptor activator of nuclear factor kappa B(RANK)to provide evidences for studying the mechanism of OC differentiation.METHODS: Eight amino acids were mutated(from DIIVVYVS into ELLAAFAA)in the fragment between the 533th and the 540th amino acids in RANK cytoplasmic domain.Eight mutant TNFR1/RANK chimeras,each consists of TNFR1(tumor necrosis factor receptor 1)extracellular domain linked to transmembrane domain and cytoplasmic domain of RANK with one amino acid mutated in cytoplasmic domain was constructed by point mutation method.After the eight mutant chimeras were finished,they were packed with plat E cell line to produce the retrovirus expressing mutant TNFR1/RANK.The bone marrow macrophages(BMMs),isolated from TNFR1/R2 double knockout mice,were infected with retrovirus derived from different mutants and infected BMMs which did not differentiated into OCs were inspected after stimulated by TNF-? and M-CSF.The fragment consisted of different amino acids in TNFR1/RANK chimeras,which couldn't induce OC formation after mutated,may be the special motif regulating OC differentiation.RESULTS: We found that all BMMs transfected by TNFR1/RANK-533,TNFR1/RANK-539 or TNFR1/RANK-540 differentiated into OCs,indicating that none of amino acids D533,V539 or S540 had an effect on OC differentiation.A fewer of BMMs transfected by TNFR1/RANK-534 differentiated into OCs,indicating that I534 had a partial effect on OC formation.Most importantly,BMMs transfected TNFR1/RANK-535,TNFR1/RANK-536,TNFR1/RANK-537 or TNFR1/RANK-538 did not differentiated into OCs,indicating each of amino acids I535,V536,V537 and Y538 played a pivotal role in OC differentiation.CONCLUSION: The amino acid fragment consists of I534,I535,V536,V537 and Y538 may be the special motif regulating OC differentiation in RANK.

Objective:To describe the cancer incidences and mortalities in Henan cancer registries in 2013.Methods:Registration data were evaluated according to the criteria of quality control of cancer registry,and the qualified data were analyzed based on areas(urban/rural), gender,age and cancer sites.The age-standardized rates were applied according to Segi's population and the fifth Chinese population census in 2000.Results:The total coverage of population from 19 qualified cancer registries data was 16,225,815(15.13%),Among which,8,370, 772(51.59%)were males and 7,855,043(48.41%)were females;and 2,819,817(17.38%)live in urban areas and 13,405,998(82.62%) live in rural areas.The crude incidence rate in Henan was 250.34/105(males:264.35/105,females:235.42/105),whereas the age-standardized incidence rates by Chinese standard population and by world standard population were 208.66/105and 207.25/105,respectively.The cumulative incidence rate(0-74 years old)was 24.31%.The cancer mortality in Henan was 161.05/105(males:185.50/105,females:134.98/105),whereas the age-standardized mortality by Chinese standard population and by world standard population were 131.18/105and 131.52/105,respectively.The cumulative mortality rate(0-74 years old)was 15.05%.Cancer incidence and mortality rates were increasing by age, reaching the peak values at 80 age group and 85 plus age group,respectively.Lung cancer,gastric cancer,esophageal cancer,liver cancer and colorectal cancer were the most common cancers ranked by the incidence rate,and the most common cause of cancer death was lung cancer,followed by gastric cancer,esophageal cancer,liver cancer and colorectal cancer.Incidence rate and mortality rate of breast cancer ranked the first and the fifth among the females,respectively.Conclusion:Cancer incidence and mortality rates were higher in the rural areas and in males than in the urban areas and in females.Lung cancer,digestive system cancers,and female breast cancer are the major cancer types that require attention for the prevention and control in Henan.

Objective: To investigate the effect of fried food intake on the pathogenesis of gastric cancer and precancerous lesions. Methods: From 2005 to 2013, the residents aged 40-69 years from 11 counties/cities where cancer screening of upper gastrointestinal cancer were conducted in rural areas of Henan province as the subjects (82 367 cases). The information such as demography and lifestyle was collected. The residents were screened with endoscopic examination. The biopsy sampleswere diagnosed pathologically, according to pathological diagnosis criteria, the subjects with high risk were divided into the groups with different pathological degrees. The multivariate ordinal logistic regression analysis was used to analyze the relationship between the frequency of fried food intake and gastric cancer and precancerous lesions. Results: The study coverd 46 425 males and 35 942 females, with a age of (53.46±8.07)years. The study collected 6 707 cases of normal stomach, 2 325 cases of low grade intraepithelial neoplasia, 226 cases of high grade intraepithelial neoplasia and 331 cases of gastric cancer. Multivariate logistic regression analysis showed that, compared with those whoeat fried food less than one time per week, fried foods intake (<2 times/week: OR=1.89, 95%CI: 1.57-2.28; ≥ 2 times/week: OR=1.91, 95%CI: 1.66-2.20) were a risk factor for gastric cancer and precancerous lesions after adjustment for age, sex, marital status, educational level, body mass index (BMI), smoking and drinking status. Conclusion The intake of fried food is a risk factor for gastric cancer and precancerous lesions. Therefore, reducing the intake of fried food can prevent the occurrence of gastric carcinoma and precancerous lesions.

Objective To evaluate the therapeutic effects and safety of acitretin for severe inherited keratodermas in children and adolescents. Methods Acitretin was given to 23 children and adolescents with either lamellar ichthyosis, bulbous ichthyosiform erythroderma, pityriasis rubra pillars, progressive sym- metrical erythrokeratoderma, keratitis ichthyosis deafness syndrome, generalized porokeratosis, inflammatory liner verrucous epidermal nevus, ichthyosis hystrix and non-bullous ichthyosiform erythroderma. The thera- peutic dosage was 0.67-1.07 mg/(kg?d),and maintenance dosage 0.08-0.94 mg/(kg?d).The effects on the patients' growth and development of the drug were evaluated based on the changes of body weight and height in the children. The total follow-up period was 6-35 months in an interval of 1-3 months. Results The considerable overall improvement was achieved after 1-6 months' treatment, with an overall clinical cure rate of 82.6%. Only one case responded poorly to the therapy. The excellent responses were observed in patients with bulbous ichthyosiform erythroderma, lamellar ichthyosis, and pityriasis rubra pillars, etc, and the much poor responses in ichthyosis hystrix. The most frequent adverse reaction was mild to moderate dry lips (65.2%),the next were pruritus(39.1%),skin fragility(34.8%),and dry mouth(30.4%).The less frequent adverse reactions were alopecia(13%),anorexia(8.7%),headache (4.3%) and hypoacusis (4.3%).No effects on the growth and development were found in those children during the follow up period. Conclusions The considerable overall improvement is achieved with the acitretin therapy for children and adolescents with inherited keratodermas, with only mild to moderate adverse reactions and no effects on the growth and development in the children.

OBJECTIVETo evaluate effect of screening of esophageal cancer at rural areas in Henan province.

METHODSAt rural areas with high incidence of upper gastrointestinal carcinoma in Henan province total of 88,263 persons with 40 to 69 years old were set to the target population of the screening by the 12 cities and countries and endoscope and pathology diagnosis were performed during 2009-2013. For patients with precancerous lesions, follow-up visits were conducted and defined as follows: once in three years for patients with mild dysplasia, once per year for moderate hyperplasia patients, the patients with severe intraepithelial neoplasia/carcinoma in situ should be treat, at least once per year for those one who didn't under treatment. The result data of screening were summarized and detection rates of esophagus hyperplasia, carcinoma in situ, early and middle-late cancer were calculated, as well as the early diagnosis rate. The result between first round and follow-up screening was compared.

RESULTSTarget population were examined in first round screening. There were 8,434 persons with above mild dysplasia and the detection rate was 9.56%, among them there were 7,224 (8.18%) cases with light-middle hyperplasia, 789 (0.89%) cases with serious dysplasia or cancer in situ, 239 (0.27%) cases with early cancer and 182 (0.21%) cases with middle-late cancer. The sum of serious dysplasia or cancer in situ and early cancer was 1 028 and the early detection rate was 84.96% (1,028/1,210). From 2012 to 2013, the follow-up screening for persons with light-middle hyperplasia which should be followed 4,230 cases, there were 2 853 people to take in screening and compliance was 67.45%. Total of 94 cases were diagnosed with cancer in situ or early cancer. The detection rate and the early detection rate were 3.29% and 100%, respectively. The rates of detection and early detection in phase of follow-up screening were statistically significantly higher than that in first round screening respectively (P<0.001).

CONCLUSIONAt rural areas of high incidence upper gastrointestinal carcinoma in Henan province, the screening with endoscope had good effect and strengthening the follow-up screening could increase the effect.

The purpose was to optimize the vitrification for porcine embryos cryopreservation. Blastocyst/Morula (5-6th day-embryos) were collected from superovulated Bama mini-pigs (sows/gilts). We compared different cryopreservation methods, cryopreservation tools, thining of zona pellucida (ZP) and recipient breeds on the efficiency of porcine embryo cryopreservation. The results showed that: in embryo survival rate and blastocyst cell number, there were no significant differences between cryopreservation method I [embryos were vitrified by two step method with open pulled straw (OPS) and glass micropipette (GMP) in solution 1 (TCM199 + 20% FBS + 10% EG + 10% DMSO) for 3 min, and solution 2 (TCM199 + 20% FBS + 20% EG + 20% DMSO + 0.4 mol/L SUC) for 1 min, stored in liquid nitrogen] and method II[Blastocysts were cultured for 25 min in NCSU23 + 7.5 microg/mL cytochalasin B, centrifuged at approximately 13 000 xg for 12-13 min, and recovered back into pNCSU23. They were then equilibrated for 5 min in 2 mol/L ethylene glycol in pNCSU23, washed quickly in the vitrification medium, 8 mol/L ethylene glycol, 7% polyvinylpyrrolidone (PVP) in pNCSU23, loaded into OPS/GMP, and plunged into liquid nitrogen]. GMP vitrification method was more suitable and efficient than OPS method (P < 0.05) in embryo survival rate (83.8% vs 77.6%) and blastocyst cell number (53.1 vs 47.5) after thawing. Thining of ZP did not increase the survival rate, but significantly improved blastocyst cell number in the survival blastcysts (60.1 and 46, P < 0.01). Local pig breeds (Fengjing sows) were more suitable as recipients for embryo transfer of vitrified/warmed blastcysts, which can improve pregnant rate and embryo efficiency.
