Objective To analyze the level and change trends of cancer mortality in the media focused area,Yingcheng of Hubei Province,to further support the authenticity and reliability of the information from media report.Methods Use the data of the first national retrospective death survey and the third national retrospective sampling death survey to describe cancer mortality and change trends in Yingcheng of Hubei Province.Results Crude cancer mortality in Yingcheng was 148.26/100 000.In the past 30 years,cancer mortality significantly increased by 9.27 times.Among 100 000 people in the county,each year 43 cases of malignant tumor death occurred more than the national average level.A variety of malignant tumors' mortality change in the county is significantly different from those of the country,such as esophageal cancer,stomach cancer did not fall but rise;liver cancer,lung cancer,leukaemia and colorectal cancer increased 5.84 times,5.61 times,5.07 times and 17.91 times more than the national average,respectively.The excess mortality rate of stomach cancer,liver cancer,lung cancer and colorectal cancer were 15.32/100 000,16.78/100 000,8.32/100 000 and 3.98/100 000 respectively.Negative binomial distribution fitting results suggest that death of stomach cancer exists village aggregation.Conclusions The level of historical cancer mortality in Yingcheng was low,but increase quickly,presently it is on the national high-incidence level.It presents the phenomenon that a variety of malignant tumors is generally on high-incidence level and stomach cancer exists village aggregation.

Objective To investigate the clinical manifestation, diagnosis, therapies and medical economics of cesarean scar pregnancy (CSP). Methods From Jan. 2005 to Dec. 2008, 96 patients with CSP treated in Obstetrics and Gynecology Hospital of Fudan University were studied retrospectively. Those cases were divided into 3 groups. Thirty-three patients were treated with methotrexate (MTX) 50 mg/m2 intravenously guttae in group A. Among that 18 cases were treated with MTX, after 5 - 10 days they underwent dilation and curettage of uterus; 15 cases were given by dilation and curettage first if the level of serum human chorionic gonadotrophin-β(β-hCG) descent less than 30% in every 48 hours for 3 times after curettage, then MTX (50 mg/m2) intravenously guttae. Sixty patients were treated with MTX 100 mg bilateral uterine artery injection and embolization in group B. After 2 days, they underwent curettage.Group C: 3 patients were treated with laparotomy lesion excision. The following clinical parameters were compared, including blood loss( M), lesion diameter (-x±s), blood β-hCG level (M)before treatment, the number of cases with myometrial thickness anterior to the CSP ≤3 mm, the resistant index (RI) ≤0. 5,expense(-x ± s), hospital days(-x ±s) in those 3 groups. The correlation of blood loss with lesion diameter and blood β-hCG level was studied. Results ( 1 ) Clinical manifestation: bleeding loss were 20 ml in MTX +curettage of group A, 10 ml in curettage + MTX of group A, 12 ml in group B and 200 ml in group C. The volume of bleeding loss in group C was significantly higher than those in group A or group B ( P ＜ 0. 01 ).The lesion diameter were ( 23 ± 15 ) mm in curettage + MTX of group A and ( 30 ± 14 ) mm of group B ,which were higher than ( 16 ± 8 ) mm of MTX + curettage of group A (P ＜ 0. 01 ). The lesion diameter of (52 ± 7 )mm in group C were significantly bigger than those in the other groups ( P ＜ 0. 01 ). The level of blood β-hCG levels were 21 592 U/L in MTX + curettage of group A, 979 U/L in curettage + MTX of group A,which reach statistical difference ( P ＜0. 05). The level of blood β-hCG levels were 11 312 U/L in group B and 101 U/L in group C. Among 28 cases with Rl≤0. 5,there was 8 cases in group A (24% ,8/33),18 cases in group B ( 30%, 18/60) and 2 cases in group C (2/3). Among 23 cases with myometrial thickness anterior to the CSP ≤ 3 mm, there was 21 cases in group B (35%, 21/60 ), which were significantly higher than 2 in group A (6%, 2/33 ) and none in group C ( P ＜ 0. 05 ). The expense were ( 5578 ± 3679) yuan in MTX + curettage of group A and (5346 ± 2765 ) yuan in curettage + MTX of group,which did not reach statistical difference (P＞0. 05). The expense were (7860 ±2104) yuan in group B,which were significantly higher than those in group A and (5004 ± 421 ) yuan in group C (P ＜ 0. 05 ). The hospital days were ( 15 ±8) days and ( 19 ± 14) days of group A, ( 16 ± 10) days in group B and ( 17 ±8)days in group C, there was no significant difference among those treatments ( P ＞ 0. 05 ). (2) Correlatin:there was positive correlation between bleeding loss and lesion diameter( r = 0. 31, P ＜ 0. 05 ) or blood β-hCG level ( r = 0. 35, P ＜ 0. 05). Conclusions MTX intravenously guttae, MTX uterine artery injection and embolization, and laparotomy lesion excision were all properly used in treatment of CSP. MTX uterine artery injection and embolization was recommended for those with big lesion, high β-hCG level, less myometrial thickness anterior to the CSP or plentiful blood supply of the lesion but the expense might be high.

Advertisement, which has strong association with the interest of media and the development of enterprise, can benefit both. The rampancy of illegal medical advertisement infringed on the interest of consumer, violated the social economic order, and even affected the image and the public trust of media. Hence, as the watchdog of medical advertisement, media should deal with the relation of the economic profit and social responsibility properly, and play a role as the transmitter of civilization.

Objective: To describe the status and trend of dietary energy, protein and fat pattern of Chinese residents. Method : 23 470 households including 68 962 subjects were randomly sampled from 132 counties in 31 provinces, autonomous regions and the municipalities. The 24 h dietary recall method for 3 consecutive days was used in dietary survey and weighing method was used for condiment intake. Results: The average energy intake per reference man per day was 9.42 MJ (2 250.5 kcal), 11.8% and 29.6% from protein and fat respectively. The percentages of energy from fat of big city residents arrived 38.4%. The percentages of energy from cereals, animal food and pure energy food were 57.9%, 12.6% and 17.3% respectively. The average protein intake per reference man per day was 65.9 g, 52%, 7.5% ,25.1% and 15.3% from cereals, bean and bean product, animal food and other foods respectively. The average fat intake per reference man per day was 76.3 g, 39.2% from animal food. Conclusion: The dietary change of Chinese residents represents the characteristics of the transition period, including the decrease of energy and protein intake per capita, decrease of the percentage of dietary energy supplied by cereals and increase of fat intake per capita,especially from animal foods, and the proportion of energy contributed by fat.

Objective To investigate the enhancing effect of apolipoprotein C3 (APOC3) on THP-1 cell adhesion to aortas of mice.Methods Microsurgery was performed to separate the aorta of C57BL/6 mice in sterile condition.After stimulated by APOC3 (100 △g/ml) in vitro for 16 h,the aorta was allowed to adhere for 1 h with CFSE labeled THP-1 cells (1 ×106/ml).Then the adhesion effect was observed,and the expressions of vascular adhesion molecule 1 (VCAM-1) and intercellular adhesion molecule 1 (ICAM-1) were detected by immunohistochemical method.Results Adhesion effect of the mice aorta with THP-1 cells in the APOC3 stimulated group was stronger than the control group.Both the expressions of VCAM-1 and ICAM-1 in aortas were increased by APOC3,but the former was significantly up-regulated than the latter.Conclusion Apolipoprotein C3 could enhance THP-1 cell adhesion to aortas of mice.

Objective To examine the variation of protein expression in nasopharyngeal carcinoma cell lines with different biological characteristics and to identify the radiobiological associated proteins. Methods Biological characteristics of 5-8F and 6-10B were compared by flow cytometry assay after irradia- tion. The total proteins of 5-8F and 6-10B were separated by immobilized pH gradient(IPG) IEF-SDS two- dimensional gel electrophoresis technique. The differentially expressed proteins were cut from the gel and di- gested into peptides for MALDI-TOF MS and the Q-TOF mass spectrometric analysis. Identification of pro- tein was made through searching in protein sequence database. Protein expressions were examined by western blot and immunohistochemistry method. Results Nine most differentially expressed proteins between 5-8F cell and 6-10B cell were identified, p73 and CK19 expression examined by western blot were conformal with that by proteomic method, p73 expression in 5-8F cell was higher than in 6-10B cell. CK19 expression in 6- 10B cell was higher than in 5-8F cell. Conclusion Differentially expression of proteins exist in nasopha- ryngeal carcinoma cell lines with different biological characteristics. These proteins may be associated with cell radiobiological characteristic with the p73 as a potential biomarker.

Objective To investigate the expression of sialic acid-binding immunoglobulin-like lectin-1 (Siglec-1) in the peripheral blood mononuclear cells (PBMCs) in patients with rheumatoid arthritis (RA),osteoarthritis (OA) and healthy controls and to explore the relationship between Siglec-1 expression and disease activity in RA.Methods Siglec-1 protein and mRNA levels were measured by flow cytometry and real-time quantitative reversetranscription-polymerase chain reaction (qRT-PCR) in 42 RA patients,28 OA patients and 26 healthy controls,respectively.The correlation studies between Siglec-1 and disease activity score 28 (DAS28) or C-reactive protein were performed.T-test was used for comparisons between groups and Pearson's correlation test was used for correlation analysis.Results The percentage of Siglec-1 positive cells of PBMCs in RA group [(15.2±7.6)％] was significantly higher than that in the OA group [(2.3 ±2.6)％] or healthy controls [(2.1±1.6)％,t=8.615,8.661; all P＜0.01].And the major cell type in PBMCs that expressed Siglec-1 was monocytes.The relative Siglec-1 mRNA expression in PBMCs in the RA group (3.4±1.5) was also significantly higher than that in the OA group (1.2±0.4) or healthy controls [(1.0± 0.4),t=3.446,3.966; all P＜0.05].But no significant differences of Siglec-1 protein and mRNA between the OA group and healthy controls were found.Furthermore,positive correlations between Siglec-1 protein and DAS28 or hs-CRP were found in RA patients (r=0.89,P＜0.01; r=0.48,P＜0.01).Conclusion PBMCs are activated which are characterized by elevated expression of Siglec-1 in RA patients.Circulating Siglec-1 may be considered as a potential noninvasive biomarker for monitoring disease activity in RA.

OBJECTIVEThe purpose of this study was to study the methods of how to puncture the temporomandibular joint (TMJ) cavity of rabbits and get the synovia.

METHODSThe authors punctured joint cavity and withdrew the synovia from bilateral TMJ cavities of 12 New Zealand rabbits with different methods, such as the traditional puncture method, improved puncture, puncture under X ray, puncture guided by ultrasonography and spiral CT, and withdrawing synovia by micropump.

RESULTSOnly one cavity was successfully punctured using the traditional puncture method. A total of 4 cases were successfully punctured using the improved method. X ray and ultrasonography did not locate the TMJ cavity precisely. The spiral CT helped observation and puncture. However, the above methods did not work in collecting synovia. The method of micropump withdrew synovia successfully.

CONCLUSIONThe improved method and spiral CT are efficient methods to precisely puncture TMJ cavity. The technique of micropump successfully resolves the problem of withdrawing synovia.

Objective To evaluate the application effect of IKAP nursing model on primipara with postpartum hypogalactia.Methods A total of 108 primiparas with hypogalactia who had delivered their babies in Quzhou Hospital of Traditional Chinese Medicine, Zhejiang province, from Feburary to August 2016 were selected and divided according to random number table into observation group (with IKAP nursing model) and control group (with routine nursing), each with 54 cases. Nursing effect, serum prolactin and nursing satisfaction were compared between the two groups.Results Total effective rate was 81.48% in the observation group, with 28 cases cured, 16 effectively treated, and 10 ineffectively treated; while total effective rate in the control group 59.26%, with 16 cases cured, 16 cases effective and 22 ineffectively treated. Before the nursing care, differences in serum prolactin levels of primiparas in the two groups were not statistically significant (t=1.205,P>0.05), while after the nursing care, the serum prolactin level of primiparas in the observation group was significantly higher than that in the control group (t=2.357,P<0.05). Among 54 cases in the observation group, 39 were very satisfied, 13 basically satisfied, and 2 dissatisfied; while in the control group, 21 were very satisfied, 22 basically satisfied, and 11 dissatisfied.Conclusions The IKAP nursing model can effectively solve hypogalactia of primiparas, improve the serum prolactin level, with high satisfaction from primiparas, which makes it worth promoting in clinic.
