OBJECTIVE To investigate the effect and mechanism of Panax notoginseng saponins （PNS） on wound healing after anal fistula surgery in rats by regulating the hypoxia-inducible factor-1α （HIF-1α）/vascular endothelial growth factor （VEGF）/ vascular endothelial growth factor receptor-2 （VEGFR2） signaling pathway. METHODS SD rats were selected to establish a postoperative rat model of anal fistula by infecting wound with Escherichia coli. The model rats were randomly grouped into model group， PNS low-dose and high-dose groups （15， 30 mg/cm2）， high-dose of PNS+2-methoxyestradiol （2ME2） group （PNS 30 mg/cm2+HIF-1α inhibitor 2ME2 4 mg/kg）， with 10 rats in each group. Another 10 normal rats were selected for back hair removal treatment as the control group. Each drug group was injected with the corresponding drug solution intramuscularly or （and） intraperitoneally， once a day， for 3 weeks. After the last administration， the wound healing rate （excluding the control group）， microvascular density （MVD）， the expression of collagen Ⅰ and fibronectin （FN） in the wound tissue were detected in each group； the levels of angiogenic factors [VEGF， E-mail：842710813@qq.com angiopoietin-Ⅰ （Ang-Ⅰ）， Ang-Ⅱ] in serum， the levels of inflammatory factors [interleukin-6 （IL-6） and IL-2] in serum binggui7183@163.com and wound tissue as well as the expressions of the related proteins of HIF-1α/VEGF/VEGFR2 signaling pathway in the wound tissue of rats were also detected in each group. RESULTS The MVD， the expression of collagen Ⅰ and FN in the wound tissue， and the levels of IL-6 and IL-2 in serum and wound tissue of rats increased significantly in the model group， compared to the control group （P＜0.05）， while the serum levels of VEGF， Ang- Ⅰ and Ang-Ⅱ decreased significantly （P＜0.05）. The wound healing rate， the MVD in wound tissue， the serum levels of VEGF， Ang-Ⅰ and Ang-Ⅱ， the expressions of collagen Ⅰ and FN in the wound tissue， and protein expressions of HIF-1α， VEGF and VEGFR2 in the PNS low-dose and high-dose groups increased significantly， compared to the model group （P＜0.05）， while the levels of IL-6 and IL-2 in serum and wound tissue decreased significantly （P＜0.05）； the high-dose PNS had a stronger effect （P＜ 0.05）. 2ME2 could weaken the effect of PNS on above indicators of rats after anal fistula surgery （P＜0.05）. CONCLUSIONS PNS can promote the production of angiogenic factors and inhibit the production of pro-inflammatory factors， thereby promoting wound healing in rats after anal fistula surgery. The above effects are related to the activation of HIF-1α/VEGF/VEGFR2 signaling pathway.

A 29-year-old man visited Zhongshan Hospital, Fudan University in December 2021. The patient presented with recurrent coughing, sputum, and wheezing, high level of serum total IgE, positive aspergillus fumigatus-specific IgE and extremely severe mixed ventilatory dysfunction. These features and thoracic CT results scan showed bronchiectasis and allergic bronchopulmonary aspergillosis. In consideration of his clinical characteristics, including low levels of fractional exhaled nitric oxide (FeNO), and nasal nitric oxide (nNO), persistent cough after birth, consanguineous marriage of his parents, etc. we ratiocinated a possibility of hereditary diseases, especially primary ciliary dyskinesia (PCD). From this perspective, whole exome sequencing (WES) was performed and the diagnosis of PCD was ultimately confirmed.

Objective: The registration data of local cancer registries from 2008 to 2012 were collected by National Central Cancer Registry to estimate the incidence and mortality of female breast cancer in China. Methods: Data from 135 registries were qualified and selected in the final analysis, and each registry at least has submitted data from 2010 to 2012. Cancer incidence and mortality analyses were stratified by area (urban/rural, eastern/middle/western areas) and age group. The age composition of standard population of Chinese census in 2000 and Segi′s population were used for age-standardized incidence and mortality in China and worldwide, respectively. Results: A total of 135 registries were recruited in the analysis, covering 629 333 910 person-years (382 669 450 in urban and 246 664 460 in rural). About 13, 258 cases of female breast cancer were diagnosed and 32 205 cases were dead between 2008 and 2012. Female breast cancer incidence was 42.67/100, 000 and age-standardized rate calculated by worldwide standard population was 28.87/100, 000. The crude incidence of urban area was 51.85/100, 000, higher than 28.29/100, 000 of rural area, and the crude incidence of eastern area was 46.35/100, 000, higher than 36.38/100, 000 of middle area and 27.60/100, 000 of western area. The age-specific incidence increased with age and reached the peak at age 55-59 (96.36/100, 000), and declined at age 60. The age-standardized incidence rate by Chinese standard population increased 30.56% from 2003 to 2012. The increase rate of rural area was 72.32%, faster than 23.48% of urban area. Female breast cancer mortality was 10.36/100, 000 and the age-standardized rate calculated by worldwide standard population was 6.61/100, 000. The crude mortality of urban area was 11.64/100, 000, higher than 8.36/100, 000 of rural area, and the crude mortality of eastern area was 10.81/100, 000, higher than 7.38/100, 000 of middle area and 9.90/100, 000 of western area. The age-specific incidence increased with age and reached the peak at age above 85 (61.25/100, 000). Age-standardized incidence rate by Chinese standard population remained stable during the period of 2003-2012 (6.23%). The mortality rate mainly increased in rural area (54.94%), while decreased 2.32% in urban area over the 10 years. Conclusions Although the incidence and mortality of breast cancer in China are comparatively low worldwide, in China the incidence and mortality of female breast cancer have rose to the first and sixth place respectively among all the female cancers. The disease burden of breast cancer is very different between urban and rural area. Therefore, the targeted measure and strategy of control and prevention according to the area difference are needed.

Objective: To analyze the patterns of female breast cancer and their incidence in Shanghai during 2003-2012, and to compare them with international data. Methods: The data of female breast cancer cases diagnosed between 2003 and 2012 were collected from the Shanghai Cancer Registry. The record of cancer cases included the patient's name, gender, date of birth, permanent and residential address, diagnosis site or name, histological type, date of first diagnosis, diagnostic basis and diagnostic stage, etc. Data source of cancer incidence of World, Developed Countries, Developing Countries, East Asia and China in 2012 sourced from GLOBOCAN 2012 database of the WHO International Agency for Research on Cancer (IARC); and the data of USA during 2008-2012 was collected from SEER 18 database from Surveillance, Epidemiology, and End Results Program of the National Cancer Institute (NCI). Incidence indicators of Shanghai female breast cancer were calculated, including the average cases, median age, average age, proportion, crude rate, age-specific rate and age-standardized rate. Results: During 2003-2012, 41 991 new cases of female breast cancer were diagnosed in Shanghai, with an average of 4 199 cases per year, accounting for 17.23% among total new female cancer cases, ranking first in female cancer incidence in Shanghai during 2003-2012, with a crude incidence rate of 60.90 per 100 000 and an age-standardized incidence rate of 33.90 per 100 000. During 2008-2012, an average 4 528 new cases of female breast cancer was diagnosed per year in Shanghai, with 16.97% among total female cancer cases. The median age was 56 years old and the mean age was 57.73 years old. The crude rate was 64.23 per 100 000 and the age-standardized rate was 35.00 per 100 0000, which was higher than those of China (22.1 per 100 000), Eastern Areas (27.0 per 100 000) and Developing Counties (31.3 per 100 000), and lower than that of World (43.1 per 100 000), and Yellow Race Population of USA (68.77 per 100 000). During 2003-2007, on average, 3 869 new cases of female breast cancer were diagnosed per year in Shanghai, accounting for 17.54% of total female cancer cases. The median age was 53 years old and the mean age was 56.44 years old. The crude rate was 57.42 per 100 000 and the age-standardized rate was 32.69 per 100 000. There was a continuing peak stage spanned 25 years old from 50 to 74 years old, during 2008-2012. Compared with those of 2003-2007, the beginning age group of the continuing peak stage was delayed for 5 years old and the ending age group was delayed for 10 years old. Conclusion The age-standardized incidence rate in Shanghai was higher than those of China, Eastern Areas and Developing Counties, and lower than that of World, and that of Yellow Race Population of USA; Compared with 2003-2007, the crude rate and age-standardized rate increased, the median age, mean age and the beginning and ending age group of the continuing peak stage were delayed.

Background and purpose:Head and neck cancer is common worldwide. This article aimed to describe the patterns of incidence of head and neck cancer and their changes in Shanghai from 2003 to 2012, in order to provide reference for prevention programs, research and control strategies on cancer.Methods:The data of lip, oral cavity and pharynx cancer cases were collected by the Shanghai Cancer Registry. The distributions of Shanghai lip, oral cavity and pharynx cancer incidences from 2003 to 2012 were described. The patterns were described according to gender, age, basis of diagnosis, histological type, diagnostic stage in detail. We compared incidences of recent 5 years (from 2008 to 2012) with those of previous 5 years (from 2003 to 2007).Results:On average from 2003 to 2012, 1105 new cases of head and neck cancer were diagnosed in Shanghai each year, with 2.08% among the total cancer cases. The crude rate was 8.01 per 100000 and the age-standardized rate was 4.45 per 100000. Nasopharyngeal cancer was the major subtype of the head and neck cancer, with 50.81% among the total head and neck cases. The crude and age-standardized rates among males were higher than those among females. The histologically verified percentage was 85.77%. The squamous carcinoma was the major histological type, with 57.58% among the total cases. The age-stan-dardized rate of nasopharyngeal cancer was in decline.Conclusion:The incidence of head and neck cancer was low in Shanghai during the past 10 years. Male cases were more than female cases. The major histological type was squamous carcinoma. Half of new cases were nasopharyngeal cancer which appeared to affect patients at a relatively young age. Patients with nasopharyngeal cancer were diagnosed at relatively advanced stages.

Background and purpose: The incidence and mortality of lung cancer ranked first in China. This study aimed to describe lung cancer survival in Shanghai, and provide background information for cancer prevention and treatment evaluation. Methods: Data of lung cancer cases diagnosed during 2002-2006, follow-up information and death report were collected from Shanghai Cancer Registry. Life table method and Ederer Ⅱ were used to calculate observed survival (OS) and relative survival (RS) respectively. Related demographic characteristics and status were also analyzed to present the survival situations of the lung cancer survivors in Shanghai. Results: In this study, 41802 lung cancer cases were included in analysis. The 5-year OS and RS for lung cancer were 13.75% and 20.23% respectively, and median survival time was 318 days. Survival rate was higher among females than males, with the 5-year OS of 15.49% and 13.00% respectively. The 5-year OS was higher among suburban residents (14.25%) than urban residents (13.23%). Survival rates decreased with increasing age and advanced stage. Patients aged 0-34 had a 5-year OS of 38.21%, while patients aged above 75 had a 5-year OS of 5.48%. Patients diagnosed with stage Ⅰ had a 5-year OS of 55.47%, while patients diagnosed with stage Ⅳ had a 5-year OS of 5.27%. Survival of lung cancer patients differed by tumor histological subtype. The 5-year OS of squamous lung cancer (24.40%) was higher than other histological types, followed by adenocarcinoma (22.26%), large cell (20.27%) and small cell lung cancer (12.22%). From 1972-1976 to 2002-2006, the 5-year OS of urban male patients increased from 6.8% to 12.4%, and 5-year OS of urban female patients increased from 7.3% to 14.9%. Analysis of RS gave the similar results. Conclusion: During the past 30 years, survival rate of lung cancer patients in Shanghai improved steadily, and the survival condition is above average among different countries and areas. However, survival rate of lung cancer is still low compared with other types of cancer. Future focus should be placed on the control of tobacco smoking, early detection by low-dose helical computed tomography and targeted therapy to further improve lung cancer survival.

Background and purpose:China is a high incidence area of liver cancer. The latest monitoring data in Shanghai show that liver cancer is one of the most common cancers with very high disease burden. This study aimed to describe and analyze the population-based survival rates of patients with liver cancer in Shanghai.Methods:Data of liver cancer cases diagnosed between 2002 and 2006, including follow-up information and death report, were collected from Shanghai Cancer Registry. Life table and Ederer Ⅱ were used to calculate observed survival (OS) and relative survival (RS). The related demographic characteristics and status were also analyzed to relfect the survival situations of the liver cancer survivors in major areas of Shanghai.Results:In this study, 20 702 liver cancer cases were included in analysis. Five-year OS rate for liver cancer was 11.72%, whereas RS rate was 15.45%. The OS of male liver cancer patients was higher than that of female patients. Patients whose age ranged from 0-34 years had the highest survival rates than patients from other age groups. The survival of patients with hepatocellular carcinoma was higher than that of patients with other histologic types of liver cancer. Signiifcant difference in survival had also been found among patients with various stages of liver cancer. The survival rate of patients with stageⅠliver cancer was much higher than that of patients with stageⅢ andⅣ liver cancers. There was no signiifcant difference in the survival of liver cancer patients between urban and rural residents. Over the past 3 decades, the 5-year OS increased dramatically in Shanghai. Conclusion:The survival of patients with liver cancer in Shanghai is improved signiifcantly. The prognosis is poor compared with other common malignant tumors. It is necessary to strengthen the risk factors and high-risk population control and intervention in the future.

Background and purpose:Incidence and mortality of gastric cancer have increased gradually in China. Population-based cancer survival rate can relfect improvements in cancer diagnosis and treatment, as well as provide evidence for gastric cancer prevention and control.Methods:Data from gastric cancer incidence and follow-up between 2002 and 2006 were collected by the Shanghai Cancer Registry. Life table and EdererⅡ were used to calculate observed survival (OS) and relative survival (RS).Results:A total number of 28 243 gastric cancer cases were documented between 2002 and 2006 in Shanghai. The 5-year OS and RS of gastric cancer were 32.15% and 45.81%, respectively. Survival rates of gastric cancer varied by age, residence, diagnostic stage, and tumor histological type, but not by gender. Patients aged 35-44 years who were diagnosed at stageⅠ or with tubular adenocarcinoma, had the highest survival rates. Moreover, patients in rural areas had higher 5-year OS than those in urban areas. During the period 2002-2006,both 5-year OS and RS of gastric cancer increased dramatically, as compared with 1972-1976. Conclusion:Survival rates of gastric cancer varied by age, residence, diagnostic stage, and tumor histological type. The 5-year OS and RS signiifcantly increased in Shanghai over the past three decades, but are still far below developed countries. Early diagnosis of gastric cancer would be an effective strategy to improve survival and prognosis of patients with gastric cancer.
