Objective To summarize the clinical presentation, pathology features, and treat-ment principle for primary testicular non-Hodgkin's lymphoma. Methods Twelve patients were di-agnosed with primary testicular lymphoma. The mean age was 62 years (36-78). Of the patients, unilateral primary testicular tumors were found in 11 cases and bilateral tumors were found in 1 case. All cases had swollen testes, 3 cases had mild pain and 1 had low-grade fever. Ultrasonic examination detected solid mass in all 12 cases. CT scan revealed retroperitoneal enlarged lymph nodes in 3 cases. Nine patients were diagnosed with disease of stage Ⅰ E, 2 of stage Ⅱ E, and 1 of stage Ⅲ E. All of the patients underwent radical orchiectomies. Postoperative treatment included: CHOP chemotherapy for 10 cases, radiotherapy after chemotherapy for 5 cases, and surgery alone for 2 cases. Results Post-operative pathology results were non-Hodgkin's lymphoma in all cases. One patient lost in follow up, one died within 2 years because of other disease. The 1, 3 and 5 year actual survival rates were 82% (9/11) ,40%(4/10),20% (2/10), respectively. The relapsed organs included contralateral testis(3/ 11), central nervous system(3/11), liver(1/11)and retroperitoneal lymph node(1/11). Conclusions The prognosis of the primary testicular non-Hodgkin's lymphoma is very poor. Chemotherapy must be used after surgery for any stage. Stage Ⅰ E and Ⅱ E patient should be treated by surgery combined with radiotherapy and chemotherapy. Contralateral testis should be irradiated prophylactically. Pa-tients beyond stage Ⅱ E should accept chemotherapy after surgery and radiotherapy according to the patient's status.

AIM To determine the antagonistic activities of new endothelin receptor antagonist CPU0214 on the left ventricle membranes and the aorta ring contraction in normal rat and its reduction effect on the mean arterial pressure in conscious DOCA salt hypertensive rats. METHODS Left ventricle membranes of normal rat hearts achieved for competition binding assay was used to investigate the antagonistic effects of CPU0214. Aorta ring contraction induced by ET 1 in normal rat was used to investigate the antagonistic activity of CPU0214. DOCA salt hypertensive rats were induced by injection of deoxycorticosterone acetate (DOCA, sc) following with 1% NaCl as drinking for 4 wk. A multiple physiological recorder was used to record the mean arterial pressure of femoral artery. The endothelin receptor change in the left ventricle membranes of DOCA salt hypertensive rat was measured by binding assays. Intraperitoneal injection of CPU0214 was used to investigate its effect on reduction of mean arterial pressure. RESULTS In the left ventricle the IC 50 of endothelin receptor antagonist CPU0214 is 16 nmol?L -1 and CPU0214 (10 ?mol?L -1 ) inhibited the ET 1 induced isolated aorta rings contraction in normal rats. Mean arterial pressure as well as B max and K d of left ventricle were increased significantly in DOCA salt hypertensive rat. CPU0214 (60 mg?kg -1 ip) significantly reduced the mean arterial pressure of conscious DOCA salt hypertensive rats especially during 60～90 min after administration. CONCLUSIONS CPU0214 has significantly antagonistic effects on the left ventricle membrane and the isolated aorta ring contraction in normal rat, which is verified by CPU0214 as a strong endothelin receptor antagonist. Furthermore its effect on the mean blood pressure reduction in conscious DOCA salt hypertensive rats, which is manifested as an abnormal endothelin system, shows its prosperity of drug development value as a new endothelin receptor antagonist.

Objective To discuss the efficacy of retroperitoneal laparoscopic dismembered pyeloplasty for pediatric ureteropelvic junction obstruction(UPJO). Methods Retroperitoneal laparoscopic dismembered pyeloplasty was performed on 24 patients with UPJO.The age of the patients ranged from 3 to 14 years(mean,7 years).The diagnosis was set up by ultrasonography,IVU,CT or magnetic resonance urography.All the patients had hydronephrosis,with 4 cases mild,10 cases moderate and 10 severe ones. Results All operations were completed laparoscopieally,without conversions to open surgery during operation.The mean operative time was 180 min(range 150 to 200).The mean blood loss was 60 ml(range 40 to 100)and the mean postoperative hospital stay was 7 d (range 5 to 9).All 24 patients were followed-up for 6 to 24 months(mean,1 4 months).There was no stricture at UPJ.Eighteen patients had complete resolution of hydronephrosis and 6 patients showed obvious alleviation in hydronephrosis. Conclusion Retroperitoneal laparoseopie dismembered pyeloplasty could be a mini-invasive,safe,and effective procedure for the treatment of UPJO in pediatric patients.

OBJECTIVETo survey the acceptance and willingness-to-pay for colorectal cancer colonoscopy screening among high risk populations in urban China.

METHODSFrom 2012 to 2013, a Cancer Screening Program in Urban China (CanSPUC) was initiated in 9 provinces, the current survey was conducted among those participants who were evaluated as "high risk for colorectal cancer" by a risk-factor-evaluation-model (community-based) and then went through a colonoscopy screening procedure (hospital-based). All the data were obtained through a questionnaire-based interview (face-to-face or self-completed), mainly focusing on the acceptance and willingness-to-pay of the participants for colorectal colonoscopy screening.

RESULTSThe current analysis included a total of 1 624 participants, with an median age of 55.0 years (P25 = 49.0, P75 = 61.0 years) and an annual income per capita of 17 thousand (range: 10-25 thousand) Chinese Yuan (CNY), 42.8% (695/1 624) of whom were males. Of all the participants, 87.0% (1 414/1 624) could totally or substantially accept the colonoscopy screening, particularly in those at higher education level (junior high school: OR = 0.34, 95% CI: 0.22-0.52; high school OR = 0.41, 95% CI: 0.26-0.66; college or over OR = 0.35, 95% CI: 0.20-0.59). Of all the participants, 13.0% (210/1 624) could not or hardly accept it, particularly in those with older age (60-69 years) (OR = 1.48, 95% CI: 1.06-2.07), not in marriage (OR = 2.15, 95% CI: 1.25-3.70) or with family member(s) to raise (OR = 1.60, 95% CI: 1.17-2.20). 1 388 (85.5%) of all the participants had willingness-to-pay for a long-term colonoscopy screening service, particularly in those working in public (OR = 0.61, 95% CI: 0.44-0.84) or enterprise sectors (OR = 0.60, 95% CI: 0.38-0.94), but 82.3% (1 141/1 386) of whom would only pay less than 100 CNY; 14.5% (236/1 624) of total had no willingness-to-pay, particularly in those living in areas with moderate (OR = 4.08, 95% CI: 2.75-6.33) or high GDP per capita (OR = 3.26, 95% CI: 2.11-4.92), or with an absence of willingness-to-pay for colonoscopy screening (OR = 3.98, 95% CI: 2.81-5.65).

CONCLUSIONSAlthough a larger community-based colorectal cancer screening program was warranted to examine the extrapolation of these findings, it suggested that the acceptance for colorectal cancer colonoscopy screening among the selected high-risk populations was considerable. The willing-to-pay was relatively high but the amount of payment was limited, the indicated subgroups with potentially less acceptance or willingness need to be more focused in the future to reach a higher participation rate. The data will also be informative in integrating the screening service into the local health insurance system.

Objective:The transjugular or transfemoral approach is used as a common method for hepatic venous pressure gradient (HVPG) measurement in current practice. This study aims to confirm the safety and effectiveness of measuring HVPG via the forearm venous approach.Methods:Prospective recruitment was conducted for patients with cirrhosis who underwent HVPG measurement via the forearm venous approach at six hospitals in China and Japan from September 2020 to December 2020. Patients' clinical baseline information and HVPG measurement data were collected. The right median cubital vein or basilic vein approach for all enrolled patients was selected. The HVPG standard process was used to measure pressure. Research data were analyzed using SPSS 22.0 statistical software. Quantitative data were used to represent medians (interquartile ranges), while qualitative data were used to represent frequency and rates. The correlation between two sets of data was analyzed using Pearson correlation analysis.Results:A total of 43 cases were enrolled in this study. Of these, 41 (95.3%) successfully underwent HVPG measurement via the forearm venous approach. None of the patients had any serious complications. The median operation time for HVPG detection via forearm vein was 18.0 minutes (12.3~38.8 minutes). This study confirmed that HVPG was positively closely related to Child-Pugh score ( r = 0.47, P = 0.002), albumin-bilirubin score ( r = 0.37, P = 0.001), Lok index ( r = 0.36, P = 0.02), liver stiffness ( r = 0.58, P = 0.01), and spleen stiffness ( r = 0.77, P = 0.01), while negatively correlated with albumin ( r = -0.42, P = 0.006). Conclusion:The results of this multi-centre retrospective study suggest that HVPG measurement via the forearm venous approach is safe and feasible.

Objective: To understand the consciousness of the cancer early detection among urban residents and identify the influencing factors from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. Self-designed questionnaires were used to collect population, socioeconomic indicators, self-cancer risk assessment, regular participation in physical examination and other information. The multivariate logistic regression model was used to identify the factors of people who had not regularly participated in the regular physical examination in the past five years. Results: The self-assessment results of 32 357 residents showed that there were 27.54% (8 882) of total study population with self-reported cancer risk, 45.48% (14 671) without cancer risk and 26.98% (8 704) with unclear judgement on their own cancer risk. Among population with cancer risk, 79.84% (7 091) considered physical examination accounted. In the past five years, there were 21 105 (65.43%) residents participated in regular physical examination and 11 148 (34.56%) participated in non-scheduled one, respectively. The multivariate logistic regression analysis showed that compared with unmarried and western region residents, divorced, middle and eastern region residents had a stronger consciousness to participate in the regular physical examination (P<0.05). Compare with residents with annual household income less than 20 000 CNY in 2014, cancer risk assessment/screening intervention population, and self-assessment with cancer risk, residents with annual household income between 20 000 CNY and 59 000 CNY in 2014, occupational population, community residents, cancer patients, self-reported cancer-free risk, and self-assessment with unclear judgement of cancer risk were less likely to participate in the regular physical examination (all P values <0.05). Conclusion From 2015 to 2017, the Chinese urban residents had a acceptable consciousness of the cancer early detection. The marital status, annual household income, population group and self-assessment of cancer risk were related to the consciousness of the cancer early detection of people who had not participated in the regular physical examination in the past five years.

Objective: To understand the consciousness of the cancer early diagnosis among urban residents and identify the related factors from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The general demographic characteristics, the consciousness of the cancer early diagnosis (whether people would have a willingness or encourage their relatives/friends to confirm the abnormal results once which were detected from the physical examination) and other information were collected by using the self-designed questionnaire. The non-conditional logistic regression model was used to identify the relateol factors related to the consciousness of the cancer early diagnosis. Results: As for residents with abnormal result from the physical examination, 89.29% (28 802) of residents would choose to seek medical treatment for further diagnosis. If their relatives/friends had abnormal results from the physical examination, 89.55% (28 886) of residents would encourage their relatives/friends to confirm the diagnosis in time. The non-conditional logistic regression model analysis showed that compared with the public institution staff/civil servants, annual household income less than 20 000 CNY, the western region and the cancer risk assessment/screening intervention population, the company staff, annual household income about 40 000 CNY and more, and the residents from the middle and eastern region had a stronger consciousness to seek further diagnosis; while the unemployed residents and community residents were less likely to seek further diagnosis (P<0.05). Conclusions From 2015 to 2017, the Chinese urban residents had a good consciousness of the cancer early diagnosis. Occupation, annual household income, residential region and population group were related to the consciousness of the cancer early diagnosis.

Objective: To investigate the demand and access to the cancer prevention and treatment knowledge and related factors among urban residents in China from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of general demographic characteristics, the demand and access to cancer prevention and treatment knowledge, and the influencing factors of the attitude. The Chi-square test was used to analyze the difference of the demand of the cancer prevention knowledge among different groups and the corresponding factors of the cancer prevention and treatment knowledge were analyzed by using the logistic regression model. Results: The proportion of residents who need the cancer prevention and treatment knowledge was 79.5%. The demand rate of the inducement, symptom and diagnosis methods of cancer in the occupational population was highest, about 66.8%, 71.0% and 20.8%, respectively. The demand rate of treatment methods and cost in current cancer patients was the highest, about the 45.9% and 21.9%, respectively. The top three sources to acquire the cancer prevention and treatment knowledge were "broadcast or television" (69.5%), "books, newspapers, posters or brochures" (44.7%) and "family and friends" (33.8%). The multivariate analysis showed that compared with public institution personnel/civil servants, unmarried/cohabiting/divorced/widowed and others, annual household income less than 20 000 CNY, from the eastern region, people without cancer diagnosis and people with self-assessment of cancer risk, the demand rate of cancer prevention and treatment knowledge was higher in enterprise personnel/workers, married, annual household income between 60 000 CNY and 150 000 CNY, from the central region, people with cancer and people with unclear cancer risk (all P values <0.05). Conclusion There was a high demand for the cancer prevention and treatment knowledge among urban residents in China from 2015 to 2017. The main access to the knowledge is from the radio or television. The occupation, marital status, annual household income, residential region, health status and risk of disease were the main factors of the demand of the cancer prevention and treatment knowledge.
