Background and purpose: Cervical cancer is one of the most common malignant tumors and poses a great threat to women's fitness. Monitoring its present status and variations over the past 3 decades could provide scientific basis for prevention and control strategies of cervical cancer in China. Methods: This study collected the mortality rates of cervical cancer data in Chinese women from 1987 to 2014, described the features and trends of age-standardized rates and truncated rates, and estimated the variations via joinpoint regression models. Results:The mortality rates of cervical cancer for rural women were roughly higher than those for urban women. It showed downward trends for both urban and rural women, and the average rate of decrease for rural women (AAPC=3.94％, P<0.01) was higher than that for urban women (AAPC=1.79％, P<0.01). The gap between urban and rural areas was narrowing, with urban rates exceeding rural rates after 2010. The mortality rates of cervical cancer increased with time for urban women aged from 30 to 54, decreased with time for the elderly urban women and all the rural women. Conclusion: The overall mortality rates of cervical cancer took a desirable turn in China over the past 3 decades, while the status for the middle-aged urban women was getting worse as well as the elderly in both urban and rural areas during the past 10 years.

To discuss clinicopathological features and molecular genetic change of congenital mesoblastic nephroma (CMN).Methods Nine cases diagnosed as CMN were analyzed retrospectively in this study.Histological features,immunohistochemical profiles and ETV6 gene rearrangement status were assessed.Results All patients were within two years of age and eight of them were within one year.The average diameter of tumors was 9.5 cm (3.2-15.0 cm).These series cases included 3 classic CMN,5 cellular CMN and 1 mixed CMN.Cystic degeneration was found in 5 cases,and cartilage islands were observed in 2 cases.Compared with classic CMN,tumor size was bigger,and hemorrhage,necrosis and mitotic figures were easily to see in cellular CMN.All the tumor cells were positive for vimentin and negative for WT-1 by immunohistochemistry.ETV6 gene rearrangement was detected in 5 cases (including 4 cellular CMN and 1 classic CMN).Three cellular CMN harbored ETV6 gene translocation,1 mixed CMN and 1 cellular CMN were negative for ETV6 gene translocation by FISH analysis.The follow up data were obtained in 7 cases and 2 cases were lost.All the 7 patients were alive without evidence of recurrence and metastasis from 5 to 46 months.Conclusion CMN is a rare infant renal tumor with unique clinicopathological characteristics.Most of cellular CMNs harbor ETV6 gene translocation.The prognosis of CMN is relative good and needs to be differentiated from other malignant renal tumors.

Purpose To quantitatively evaluate the severity of brain damage in the acute phase of CO poisoning using intravoxel incoherent motion imaging.Materials and Methods MRI scans were performed in 26 patients with CO intoxication of acute stage and 18 healthy controls with matched age and gender.The difference of D value,D* value and f value in different ROIs between the poisoning and the control groups were compared,and the best cut-off values were determined.The correlation between the consciousness state and the D value as well as f value in the vulnerable area of the brain (globus pallidus) was analyzed.Results Compared with control group,the D and F value of the poisoning group were decreased in multiple ROIs,of which statistical significance was observed in the f values in the centrum semiovale,globus pallidus and thalamus,and the D values in the centrum semiovale,lateral ventricle,globus pallidus and corpus callosum splenium (P＜0.05).The best cut-off value,sensitivity and specificity were as follows:fcs=51％,77％,73％;fga=61％,77％,83％;ft=80％,85％,64％;D,=0.69×10-3 mm2/s,85％,83％;Dlv=0.65× 10-3 mm2/s,73％,89％;Dga=0.68× 10-3 mm2/s,62％,83％;Dccs=0.70× 10-3mm2/s,81％,89％.The disturbance of consciousness was positively correlated with decrease of D value and f value (rD=0.828,rf=0.745,P＜0.05).Conclusion The D and f values of intravoxel incoherent motion imaging can quantitatively evaluate the brain damage severity in acute CO poisoning.

Objective: To evaluate the potential dosimetric beneifts and optimal indications of intensity modulated radiation therapy (IMRT) and hybrid intensity modulated radiation therapy (Hybrid IMRT) for the left side breast cancer patients after breast-conservation therapy.
Methods: Eight patients with left breast carcinoma who received breast-conservation surgery were selected for this study. Two plans were designed in 3-dimensional treatment planning system. The dose distributions of target volume and normal tissues, conformal index (CI) and heterogeneous index (HI) were analyzed by dose-volume histogram (DVH).
Results: The PTV coverage was the same in the two radiotherapy plans. A better dose uniformity throughout the whole breast in Hybrid IMRT plan was achieved. The CI, the percentage of PTV receiving more than 105% prescribed dose (V105%), the percentage of PTV receiving more than 110% prescribed dose (V110%), and the Dmax, Dmin and Dmean of PTV were similar in the two plans. We compared the Hybrid IMRT with IMRT: V13of the ipsilateral lung decreased from 27.66% to 20.7%, V5 of the contralateral lung decreased from 8.01% to 2.25%, V10 and V20 of the heart decreased from 35.23% and 16.77% to 19.22% and 10.6% respectively, V5 and V10 of the contralateral breast decreased from 35% and 10.39% to 20.38% and 5.7% respectively, all with significant difference. V30 and V40 of the ipsilateral lung and V40 of the heart increased by 1.28%, 1.48%, and 2.48%, with signiifcant difference.
Conclusion: Hybrid IMRT is a better choice for patients whose treatment position is inaccurate or cannot be repeated well.

To investigate physicians' knowledge about chronic obstructive pulmonary disease (COPD) in tertiary hospitals in northeast China.Physicians from 77 tertiary hospitals in northeast China were surveyed with a questionnaire,which included questions such as risk factors,symptoms,exacerbations,comorbidities and diagnostic criteria of COPD.Besides cigarette smoking,air pollution and pulmonary infections,only 22.5％ (40/178) physicians recognized that the biomass fuels may induce COPD.Totally 59.0％ (105/178) physicians recognized the importance of spirometry to the diagnosis of COPD.Besides dyspnea,cough,sputum production,wheezing and chest tightness,only 23.7％ (42/177)of physicians considered that limitation of activity was an important symptom of COPD.65.5％ (116/177)physicians believed that recurrent lung infections was one of the most important comorbidities of COPD.However,less than 30％ [20.9％ (37/177)-28.8％ (51/177)] physicians were aware of the other important comorbidities.The physicians of tertiary hospitals in northeast China need to be systematically educated on COPD to meet the new guideline.

Objective To explore the expression of Metastasis-associated in colon cancer-1 (MACC1) in patients with nasopharyngeal carcinoma (NPC), and its relationship with clinical pathologic characteristics and prognosis Methods The expression of MACC1 was detected in 130 cases of NPC and the relationship among the MACC1 expressions, clinical pathologic characteristics and prognosis of NPC was analyzed. Results Positive expression rate of MACC1was 68.5% in the NPC and MACC1 expression was associated with advanced T stages, lymph node metastasis and advanced clinical stages of NPC (P < 0.05). The results of Kaplan-Meier survival analysis showed that the five year overall survival rate in patients with positive expressions of MACC1 (45.9%) was significantly lower than that of those with negative expressions (73.7%) and the difference was statistically significant (P < 0.05), Cox multi-factor analysis results showed that MACC1 expression was an independent prognostic factor for NPC (P = 0.004). Conclusion MACC1 abnormal expression is closely related to the invasion and metastasis of NPC and it is expected to become a new target for gene therapy of NPC.

Objective To compare the features of OCT angiography (OCTA) between neovascular agerelated macular degeneration (nAMD) and myopic ehoroidal neovascularization (mCNV) patients before and after intravitreal anti-VEGF treatment.Methods A prospective cohort study.Twenty-nine patients (37 eyes) with nAMD (19 males and 10 females,aged 68.20±8.76) and 31 patients (34 eyes) with mCNV (9 males and 22 females,aged 43.10± 11.80,with the mean diopter of-9.71 ± 1.20 D) from Department of Ophthalmology,West China Hospital of Sichuan University during May and December 2017 were included in this study.Ranibizumab or Conbercept (0.5 mg/0.05 ml) was intravitreally injected in all eyes.The patients were follow-up for 3-6 months.The OCTA was conducted before treatment and 1 day,1 week,1 month and 3-6 months after treatment.In order to ensure that the scanning position was the same,the tracking mode was adopted for each scanning.According to the OCTA images,the lesion area,parafoveal superficial vessel density and perfusion area were measured and analyzed contrastively between nAMD and mCNV patients.Results The mean lesion area before and 1 month after treatment in nAMD patients were 0.38± 1.87 mum2 and 0.06±0.12 mm2,while in mCNV patients,those were 0.26± 1.06 mm2 and 0.03 ± 0.05 mm2,respectively.There were statistically significant differences (Z=4.181,4.475;P＜0.001) in CNV lesion area before and 1 month after treatment between nAMD and mCNV patients.Compared with those before treatment,the absolute change (Z=1.853,P=0.064) and the percentage changes (t=2.685,P=0.010) of CNV lesion area l month after treatment in nAMD and mCNV patients show a statistical meaning.There were significantly decreases in both parafoveal superficial vessel density (F=8.997,P=0.003) and perfusion area (F=7.887,P=0.015) 3 months after treatment in nAMD patients,while decreases in parafoveal superficial vessel density (F=11.142,P=0.004) and perfusion area (F=7.662,P=0.013) could be detected 1 day after treatment in mCNV patients,before rising 1 month after treatment.Conclusions There are significantly differences in lesion area before and after the treatment of intravitreal anti-VEGF between nAMD and mCNV patients by OCTA examination.Moreover,the changes of both parafoveal superficial vessel density and perfusion area after anti-VEGF treatment are statistically different in two groups.

Objective:To observe different efficacies of low-frequency electroacupuncture (EA) on pancreatic endocrine system in male and female patients with simple obesity due to spleen deficiency-related dampness.Methods:A total of 80 simple obesity patients were assigned to a male group (n=37) and a female group (n=43). Both groups received a 30-minute low-frequency EA at Yinlingquan (SP 9), Sanyinjiao (SP 6), Zusanli (ST 36), Fenglong (ST 40), Quchi (LI 11), Tianshu (ST 25), Zhongwan (CV 12), Shuifen (CV 9), Qihai (CV 6) and Guanyuan (CV 4). The treatment was done once a day, and 10 times made up a course of treatment. Patients in both groups were treated for 2 courses. Then the changes in body mass index (BMI), serum insulin, insulin antibodies and leptin level in the two groups were observed and analyzed.Results:After treatment, the BMI, serum insulin, insulin antibodies and leptin levels were significantly reduced in both groups (P<0.01 orP<0.05); the BMI and serum insulin concentration were more significantly reduced in the male group than those in the female group (bothP<0.01); and the leptin level was more significantly reduced in the female group than that in the male group (P<0.01).Conclusion: EA can significantly regulate BMI and pancreatic endocrine system in both men and women with simple obesity; however, there is a gender difference: better effect for men in reducing BMI and serum insulin and better effect for women in reducing serum leptin level.

Objective:To study the relationship between cytotoxic T lymphocyte antigen 4 (CTLA-4) gene + 49A/G polymorphism and the risk of periodontitis.Methods:A comprehensive literature research was electronically performed to retrieve currently published studies regarding the association of CTLA-4 gene +49A/G polymorphism with periodontitis susceptibility.The individual OR with 95％ CI was pooled to calculate the strength of the association using RevMan 5.2 software.Results:4 out of 18 seached studies satisfied the standard for Meta-analysis.A total of 702 cases and 926 controls were finally included in the Meta-analysis.Overall,no significant association of CTLA-4 gene + 49A/G polymorphism with the risk of periodontitis was observed (P ＞ 0.05).In the subgroup analysis by ethnicity,the results showed a significant association of CTLA-4 gene + 49A/G polymorphism with increased risk of periodontitis in Asian population(P ＜ 0.05) but not in Caucasian population(all P ＞ 0.05).The stratification analysis by subtypes of periodontitis revealed no significant association of the polymorphism with chronic and aggressive periodontitis respectively (all P ＞ 0.05).Conclusion:The present studies suggest that CTLA-4 gene + 49A/G polymorphism may be not associated with the risk of periodontitis in the overall population,but correlated with an increased risk of periodontitis in Asian population.
