Objective To investigate the survival rates of main malignant tumors in Nanhui district. Methods Total 5 783 cases, registered as new cases with malignant neoplasm from 2002 to 2004 in Nanhui, were followed up. Data was studied by survival analysis with SPSS 13.0 of life table and Kaplan -Meier. Results The average annual crude incidence of malignant tumors was 267.57 / 100 000, the World standardized incidence rate of 209.98 / 100 000. Cancer Incidence in the top five ranks followed by lung, liver, stomach, colon and esophageal cancer, the incidence was 43.06 / 100 000, 28.65 / 100 000, 26.82 / 100 000, 18.63 / 100 000 and 9.57 / 100 000, respectively. The difference of the survival rates between the top five cancers was remarkable. Survival rates of cancers among males from the lowest to the highest were liver, lung, esophagus, stomach and intestines. Survival rates of cancers among females from the lowest to the highest were of liver, lung, esophagus, stomach, intestines, cervical and breast. The male or female main cancer's relative survival rate droped along with the age rising. Conclusion The survival status was better in the patients with intestine cancers and female patients with breast cancer, but worse in patients with liver, ung and esophageal cancer.

AIM: To investigate the possibility of 3T3 fibroblast growth on blood fibrin clot in culture medium with recombinant human basic fibroblast growth factor (rhbFGF). METHOD: Growth of the cells on blood fibrin clot was studied by phase-contrast, scanning and transmission electron microscopy and by Giemsa stain and MTT assay. RESULTS: The optimal concentration of rhbFGF for proliferation and survival of the cells was 100 ng/mL. The cells also grew on blood fibrin clot scaffold in the low-serum medium containing 100 ng/mL rhbFGF, and a greater number of the cells survived after 48 hours incubation compared to that after 24 hours. The elongated filopodia appeared to bridge the gaps among the fibroblasts after 24 hours incubation. Further incubation to 72 hours, a greater number of platycytes were found to be joined together by lamellopodia. CONCLUSION: 3T3 fibroblasts could grow and survive on blood fibrin clot in the low-serum medium containing rhbFGF, and a combination of blood fibrin clot and rhbFGF may have over proportional effects on wound healing.

ConclusionThe giant pelvis's application can enhance the teaching effect enormously in the childbirth turning point teaching, and this method has the application and the promoted value.

AIM: To investigate the behaviour of 3T3 fibroblast and macrophage co-culture on blood fibrin clot or adipose tissue with recombinant basic fibroblast growth factor (rhbFGF). METHODS: MTT method, inverted contrast microscopy, Giemsa staining as well as scanning electron microscope were used in the present study. RESULTS: The effect of rhbFGF on co-culture of 3T3 fibroblast and mouse macrophage on blood fibrin clot in low-serum DMEM with rhbFGF were monitored, and 3T3 fibroblast and macrophage growed well on the blood fibrin blot in low-serum DMEM with rhbFGF. CONCLUSION: The blood fibrin clot, with its low immunogenicity, could be used as a bionic support for three-dimensional tissue culture, and also a physiological carrier to distribute the growth factor rhbFGF for the cells.

Objective:To explore the efficacy and prognostic factors of intensity-modulated radiotherapy (IMRT) in elderly patients with locally advanced esophageal cancer.Methods:The clinical data of 87 elderly patients with locally advanced esophageal cancer who received IMRT and 79 elderly patients with locally advanced esophageal cancer who received three-dimensional conformal radiotherapy (3DCRT) from January 2005 to December 2015 in Changzhou Cancer Hospital Affiliated to Soochow University were retrospectively analyzed, and their efficacy and adverse reactions were observed. The log-rank test and Cox proportional hazards model were used for univariate and multivariate analyses to analyze the prognostic factors of patients receiving IMRT.Results:In the IMRT group, 27 cases (31.0%) achieved complete remission, and 60 cases (69.0%) achieved partial remission; in the 3DCRT group, 18 cases (22.8%) achieved complete remission, and 61 cases (77.2%) achieved partial remission. There was no statistical difference in the short-term efficacy (CR+PR) between the two groups ( χ2 = 1.43, P = 0.232). The 1-, 3-, and 5-year overall survival rates in the IMRT group were 77.0%, 46.0% and 23.0%, respectively, and the 3DCRT group were 70.1%, 40.5% and 10.1%, respectively. There was a statistical difference in the overall survival between the two groups ( χ2 = 4.89, P = 0.027). For elderly patients with locally advanced esophageal cancer who received IMRT, univariate analysis showed that gender, lesion location, T stage, gross tumor volume, and short-term efficacy were prognostic factors (all P < 0.05); multivariate analysis showed that lesion location, T stage, gross tumor volume, and short-term efficacy were independent prognostic factors (all P < 0.05). In the IMRT group, the incidence rate of ≥ grade 2 radiation pneumonitis was 10.3% (9/87), the incidence rate of ≥ grade 2 radiation esophagitis was 32.2% (28/87), the incidence rate of leukopenia was 18.4% (16/87), and the incidence rate of hemoglobin reduction was 7.0% (6/87), and there was no statistical difference in the incidence of acute adverse reactions between the IMRT group and the 3DCRT group (all P > 0.05). Conclusions:IMRT has more advantages than 3DCRT in the treatment of elderly patients with locally advanced esophageal cancer, especially those with upper cervical and thoracic lesion, T 1-3 stage, gross tumor volume ≤40 cm 3, and complete remission in a short term can benefit from it, and the adverse reactions are mild.

Objective:To compare the efficacy and safety of stone extraction with a single peroral choledochoscopy system under direct visualization and conventional X-ray endoscopic retrograde cholangiopancreatography (ERCP) for non-difficult common bile duct stones.Methods:A total of 164 patients with common bile duct stones who underwent stone extraction by using the single peroral choledochoscopy system under direct visualization (the observation group, n=82) and conventional X-ray endoscopic retrograde cholangiopancreatography (ERCP) (the control group, n=82) from January 2018 to April 2022 in Dongfang Hospital, Beijing University of Chinese Medicine were enrolled. The observation group was directly selected from the database, while the control group was randomly matched by age stratification with baseline data validated. The success rates of intubation, stone removal, postoperative complication incidence, and radiation exposure between the two groups were compared. Results:There was no significant difference between the baseline data of the observation group and the control group ( P>0.05). The number of patients with detected stones≥2 in the observation group and the control group were 59 (71.95%) and 37 (45.12%) respectively with significant difference ( χ 2=12.16, P=0.001). The success rates of bile duct intubation in the observation group and the control group were both 100.00% (82/82). The success rates of stone extraction were 98.78% (81/82) and 100.00% (82/82) respectively with no significant difference ( P>0.05). The one-time stone removal rates of the two groups were 93.90% (77/82) and 92.68% (76/82) respectively with no significant difference ( χ2=0.10, P=0.755). There was no significant difference in the incidence of postoperative complications between the observation group and the control group ( P>0.05). The amount of intraoperative ray exposure volume in the observation group was significantly lower than that of the control group [10.20 (6.69, 18.94) mGy VS 15.41 (10.70, 22.77) mGy, U=2 462.00, P=0.003]. Conclusion:The efficacy and safety of stone extraction with single peroral choledochoscopy system under direct visualization are comparable to those of traditional X-ray ERCP for non-difficult common bile duct stones, but it can significantly reduce the intraoperative ray exposure volume during therapeutic ERCP stone extraction.

Objective: To analyze the status of dietary sodium intake of Chinese adult residents in fifteen provinces in 2015. Methods: Data were collected from 2015 China Nutrition Transition Cohort Study. This cohort study used a three consecutive 24-h retrospective method to record food intake and weighing method to record household condiment consumption. In this study, 14 847 residents aged 18 years and over with complete data from 15 provinces in 2015 were selected for the comparison of dietary sodium intake (median) with different characteristics. Results: Among the 14 847 residents, 47.1% were males, and the rural and northern residents accounted for 60.1% and 37.7%, respectively. Median sodium intake was 3 960.0 mg/d among residents in 2015. The sodium intake of males (4 272.1 mg/d) was higher than that of females (3 716.6 mg/d). Across age subgroups, sodium intake was highest among residents aged 45-59 years (4 257.0 mg/d; 18-44 years old, 3 867.1 mg/d; ≥60 years old, 3 799.0 mg/d). Sodium intake was higher in rural area (4 042.9 mg/d) than in urban area (3 866.8 mg/d), higher in north (4 229.2 mg/d) than in south (3 806.8 mg/d) (all P values <0.05). 11.8% of residents with dietary sodium intake were below 2 000 mg/d. The main sources of dietary sodium were condiments (79.4%), regular cooking foods (11.9%) and processed foods (8.7%). Among the condiments, the salt and soy sauce accounted for 63.6% and 10.4%, respectively. Conclusion In 2015, Chinese adult residents had higher dietary sodium intake with gender and regional differences. Condiments were the main source of dietary sodium.
