OBJECTIVETo evaluate the result of colorectal cancer screening for high-risk groups in Harbin, China from 2012 to 2015.
METHODSAccording to the Project of National Colorectal Cancer Screening in Urban Area, epidemiological investigation and cancer risk evaluation established by National Cancer Center were performed among 40-69 years old residents in Harbin. Questionnaires were issued to assess high-risk groups for clinical screening, including colonoscope examination. The results of colorectal screening were evaluated in detail.
RESULTSProject of Colorectal Cancer Screening in Urban Area was completed successfully from 2012 to 2015 in various districts of Harbin. The accomplishment of high-risk assessment included 3 017 people, while 2 996 people received the clinical screening, including 1 376 males and 1 629 females, from 40 to 69 (53.3±7.1) years old. Among 2 996 people, 1 158 cases of colorectal polyps(38.7%) were screened, including 36.6%(901/2 465) cases of age<60 and 48.4%(257/531) cases of age>60 years old with significant difference (χ=19.19, P<0.01), and 47.6% (651/1 367) cases of male and 31.1%(507/1 629) cases of female with significant difference (χ=85.33, P<0.01). Of 1 158 polyps patients, 141 received the pathological examination and 11 patients were diagnosed as colorectal cancer, accounting for 0.4% of overall screening people (11/2 996). All these 11 patients underwent operation by advice and the postoperative pathology results all indicated early adenocarcinoma. Furthermore, among 141 polyps patients, 97 cases of tubular adenoma were found, which were distributed as follows: 2 cases of cecum (2.1%), 14 cases of ascending colon(14.4%), 12 cases of transverse colon (12.4%), 15 cases of descending colon (15.5%), 35 cases of sigmoid colon (36.1%) and 19 cases of rectum(19.6%).
CONCLUSIONWith the increase in age, the risk of colorectal polyps is significantly elevated. The males have higher incidence of colorectal polyps than the females. Adenoma mainly locates in the distal colon and rectum, especially in the sigmoid colon. Early screening for high-risk group can find out colorectal precancerosis and cancer, so the patients can receive early treatment.

Abstract: To date, the investigation of the functional composition of Centella asiatica (L.) Urban has been mainly focused on the triterpenoid saponins, with little research on the other compositions. The acetic acid-induced writhing, Eddy's hot plate and formalin tests were employed to investigate the anti-nociceptive effects of madecassic acid (MA). The experiment was divided into normal control group, acetylsalicylic acid (ASA) group, and the MA groups of low (10 mg/kg), medium (20 mg/kg) and high (40 mg/kg) dosage. Meanwhile, the anti-nociceptive effect of MA on the acetic acid and formalin-induced nociceptive models in the absence and presence of NAL (naloxone hydrochloride) was evaluated. To have an insight into the anti-nociceptive mechanisms of MA, the capsaicin- and glutamate-induced paw licking tests were also employed to evaluate the involvement of the vanilloid and glutamatergic systems, respectively. Results showed that MA exhibited good anti-nociceptive activity in the acetic acid-induced writhing test and the second phase of formalin test; the anti-nociceptive effect of MA in both the acetic acid and formalin-induced nociception was not effectively removed by NAL; MA (20 mg/kg and 40 mg/kg) effectively reduced the duration of biting/licking the capsaicin-injected paw with inhibition rates of 29.5% and 64.4%, respectively; MA (20 mg/kg and 40 mg/kg) distinctly shortened the time spent in biting/licking the glutamate-injected paw by 30.9% and 56.1%, respectively. In summary, MA induces significant peripheral anti-nociceptive effect, and the anti-nociceptive activities probably involve the modulation of glutamatergic systems and vanilloid systems (TRPV1) instead of the opioidergic system.

Objective: To explore the effectiveness and cost of breast cancer screening strategy that is suitable for the current econom-ic conditions in China. Methods: We collected clinical and cost information of breast cancer screening for Chinese women based on previous screening programs conducted from February 2008 to December 2011 and collected the same information about breast can-cer cases diagnosed in hospitals at the same time. Markov models were developed to analyze the incremental cost-effectiveness ratios (ICER) for 132 breast cancer screening strategies compared to no screening for Chinese women. Results: In 2010, as compared to no screening, the most cost-effective breast cancer screening strategy was biennial screening with clinical breast examination (CBE) and breast ultrasound, in parallel, for women aged between 40 to 64. This screening strategy could save 1,394 quality-adjusted life years (QALY) per 100,000 women, and the cost of saving breast-cancer related QALY would be 91,944 RMB. Sensitivity analysis indicated that in 2016, the most cost-effective breast cancer screening strategy was biennial screening with CBE and mammography (MAM), in parallel, for women aged 40 to 64, with ICER of 159,637 RMB per QALY. Conclusions: Population-based breast cancer screening would be acceptable in the current conditions in China. As the Chinese economy and level of medical care improve, breast cancer screening would be more cost-effective.

Breast cancer is the most common cancer for Chinese women. Early screening is the best way to improve the rates of early diagnosis and early treatment of breast cancer. The peak ages of breast cancer in Chinese women are obviously different from those in the European and American countries. It is imperative to develop a guideline for breast cancer screening that is suitable for Chinese women. Based on the analysis and summary of breast cancer screening data in China, and the latest guidelines and consensus on breast cancer screening in Europe, the United States and East Asia, China Anti-Cancer Association and National Clinical Research Center for Cancer (Tianjin Medical University Cancer Institute and Hospital) has developed a population-based guideline for breast cancer screening in Chinese women. This guideline has provided detailed recommendations on the screening starting age, screening modalities, and screening interval in Chinese women with average risk and high risk of breast cancer, respectively. This article aims to interpret the above guideline, providing references for professionals in breast cancer screening.

Objective:To investigate the clinical efficacy of radical resection of rectal cancer with different surgical approaches and influencing factors of postoperative complications.Methods:The retrospective study was conducted. The clinicopathological data of 3 418 patients who underwent radical resection of rectal cancer in the Second Affiliated Hospital of Harbin Medical University from July 2011 to September 2020 were collected. There were 2 060 males and 1 358 females, aged (61±11)years. Patients meeting the requirements of radical resection and surgical indications underwent surgeries choosing from open radical colorectal cancer surgery, laparoscopic radical colorectal cancer surgery, and natural orifice specimen extraction surgery (NOSES). Observation indicators: (1) intraoperative and postoperative conditions of patients undergoing different surgical approaches; (2) comparison of preoperative clinical characteristics in patients undergoing different surgical approaches; (3) comparison of postoperative histopathological characteristics in patients undergoing different surgical approaches; (4) postoperative complications of patients undergoing different surgical approaches; (5) analysis of influencing factors of postoperative complications. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(range), and comparisons between groups was analyzed using the Kruskal-Wallis rank test. Comparison of ordinal data was analyzed using the non-parameter rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Multivariate analysis was conducted using the Logistic regression model. Results:(1) Intraoperative and postoperative conditions of patients undergoing different surgical approaches. Of the 3 418 patients, 1 978 cases underwent open radical colorectal cancer sur-gery, 1 028 cases underwent laparoscopic radical colorectal cancer surgery and 412 cases underwent NOSES, respectively. The operation time, volume of intraoperative blood loss, cases with permanent stoma, preventive stoma or without fistula, time to postoperative first flatus, time to postoperative liquid food intake, cases transferred to intensive care unit after surgery, duration of postoperative hospital stay were 145(range, 55?460)minutes, 100(range, 30?1 000)mL, 435, 88, 1 455, 72(range, 10?220)hours, 96(range, 16?296)hours, 158, 10(range, 6?60)days, respectively, in patients undergoing open radical colorectal cancer surgery. The above indicators were 175(range, 80?450)minutes, 50(range, 10?800)mL, 172, 112, 744, 48(range, 14?120)hours, 72(range, 38?140)hours, 17, 9(range, 4?40)days, respectively, in patients undergoing laparoscopic radical colorectal cancer surgery and 180(range, 80?400)minutes, 30(range, 5?500)mL, 0, 45, 367, 48 (range, 14?144)hours, 72(range, 15?148)hours, 1, 6(range, 3?30)days, respectively, in patients undergoing NOSES. There were significant differences in the above indicators among the patients undergoing different surgical approaches ( H=291.38, 518.56, χ2=153.82, H=408.86, 282.97, χ2=78.66, H=332.30, P<0.05). (2) Com-parison of preoperative clinical characteristics in patients undergoing different surgical approaches. The gender, age, body mass index, cases with diabetes, cases with hypertension, cases with coronary heart disease, cases with anemia, cases with hypoproteinemia, cases with intestinal obstruction, tumor location, preoperative carcinoembryonic antigen, preoperative CA19-9 showed significant differences among patients undergoing open radical colorectal cancer surgery, laparoscopic radical colorectal cancer surgery and NOSES ( P<0.05). (3) Comparison of postoperative histopathological characteris-tics in patients undergoing different surgical approaches. Tumor histological type, tumor differentiation degree, tumor diameter, number of lymph node detected, nerve invasion, vascular invasion, lymph node invasion, tumor T staging, tumor N staging, tumor M staging, tumor TNM staging showed significant differences among patients undergoing open radical colorectal cancer surgery, laparos-copic radical colorectal cancer surgery and NOSES ( P<0.05). (4) Postoperative complications of patients undergoing different surgical approaches. Cases with postoperative complications as anastomotic leakage, abdominal infection, intestinal obstruction, anastomotic bleeding, incision complications, pulmonary infection, other complications were 52, 21, 309, 8, 130, 51, 59, respectively, in patients undergoing open radical colorectal cancer surgery. The above indicators were 33, 17, 75, 3, 45, 58, 9, respectively, in patients undergoing laparoscopic radical colorectal cancer surgery and 13, 4, 8, 0, 11, 10, 15, respectively, in patients undergoing NOSES. There were significant differences in the intes-tinal obstruction, incision complications, pulmonary infection, other complications among patients undergoing different surgical approaches ( χ2=122.56, 13.33, 20.44, 15.59, P<0.05) and there was no significant difference in the anastomotic leakage, abdominal infection, anastomotic bleeding among patients undergoing different surgical approaches ( χ2=0.96, 2.21, 3.08, P>0.05). (5) Analysis of influencing factors of postoperative complications. ① Analysis of influencing factors of intestinal obstruction in patients with radical resection of rectal cancer. Age as 20?39 years and 40?59 years, surgical approach as laparoscopic radical colorectal cancer surgery and NOSES were independent protective factors of intestinal obstruction in patients with radical resection of rectal cancer ( odds ratio=0.46, 0.59, 0.43, 0.13, 95% confidence interval as 0.21?1.00, 0.36?0.96, 0.33?0.56, 0.06?0.27, P<0.05). ② Analysis of influencing factors of incision complications in patients with radical resection of rectal cancer. Body mass index as 24.0?26.9 kg/m 2, surgical approach as laparoscopic radical colorectal cancer surgery and NOSES were independent protective factors of incision complications in patients with radical resection of rectal cancer ( odds ratio=0.24, 0.63, 0.46, 95% confidence interval as 0.11?0.51, 0.44?0.89, 0.24?0.87, P<0.05). ③ Analysis of influencing factors of pulmonary infection in patients with radical resection of rectal cancer. The surgical approach as laparoscopic radical colorectal cancer surgery was an independent risk factor of pulmonary infection in patients with radical resection of rectal cancer ( odds ratio=2.15, 95% confidence interval as 1.46?3.18, P<0.05), and tumor TNM staging as 0?Ⅰ stage was an independent protective factor ( odds ratio=0.10, 95% confidence interval as 0.01?0.88, P<0.05). ④ Analysis of influencing factors of other complica-tions in patients with radical resection of rectal cancer. Age as 20?39 years, 40?59 years, 60?79 years, body mass index as <18.5 kg/m 2, 18.5?23.9 kg/m 2, 24.0?26.9 kg/m 2, 27.0?29.9 kg/m 2, surgical approach as laparoscopic radical colorectal cancer surgery were independent protective factors of other complications in patients with radical resection of rectal cancer ( odds ratio=0.10, 0.29, 0.37, 0.08, 0.22, 0.35, 0.32, 0.29, 95% confidence interval as 0.01?0.81, 0.13?0.64, 0.17?0.78, 0.02?0.40, 0.09?0.52, 0.15?0.83, 0.12?0.89, 0.14?0.59, P<0.05). Conclusions:Compared to laparoscopic radical colorectal cancer surgery and NOSES, open radical colorectal cancer surgery has wide indication and short operation time, but less perioperative treatment effect. Laparoscopic radical colorectal cancer surgery and NOSES can achieve better surgical result and less postoperative complication when patients meeting surgical indications.
