Objective To investigate the morbidity rate of hyperuricemia and its association with hypertriglyceridemia and hypertension in elderly people in Fujian Quanzhou.Methods A crosssectional population survey for hyperuricemia was performed in Fujian Quanzhou.Questionnaire and physical examination were conducted in 1358 subjects.The levels of serum UA and lipid-profile as well as blood pressure were measured.Results In the same aged group,the level of blood uric acid was significantly higher in male (371.7±83.6) μmol/L than in female (294.8±66.5) μmol/L (t=15.8,P＜0.01).Blood uric acid concentration was gradually increased with aging in the group at age 40-70 years,but was gradually decreased with aging in female group aged over 70 years (F=12.1,P＜0.01).The total morbidity rate of hyperuricemia was 18.6％.The incidence of hypertriglyceridemia or hypertension in female with hyperuricemia was higher than those with normouricemia (22.1％ vs.10.5％,59.1％ vs.26.2％,x2=16.3,65.0,all P＜0.01).The incidence of hypertension in male with hyperuricemia was higher than those with normouricemia (54.6％ vs.42.8％,x2=4.0,P＜0.05).Conclusions The morbidity rate of hyperuricemia in elderly people is higher in south China coast than other region of China.The incidence of hypertriglyceridemia and hypertension in people with hyperuricemia is significantly higher than those with normouricemia.

OBJECTIVETo assess the accuracy of immunological fecal occult blood test (iFOBT) for detection of colorectal cancer (CRC).

METHODSA total of 1 197 studies published before June 2014 were selected from PubMed and Embase and 17 of which were finally included in this meta-analysis. A bivariate mixed-effects models was used for overall value merging and heterogeneity testing. In addition to the overall sensitivity and specificity, the analyses were also performed among certain subgroups, including a "colonoscopy group" (all were referred for colonoscopy diagnosis regardless screening results) and a "follow-up group" (only the screening positive were referred and all were then followed up), a qualitative group and a quantitative group (classified by the way of iFOBT result reading).

RESULTSA total of 161 502 subjects aged from 48 to 63 years were included in the analysis. IFOBT had an overall integrated sensitivity of 0.85 (95% CI: 0.79-0.89) (heterogeneity test: Q = 59.67, P < 0.001) and an overall integrated specificity of 0.93 (95% CI: 0.92-0.94) (heterogeneity test: Q = 1 722.53, P < 0.001) for detection of CRC. In the subgroup analysis, it was found that in the "colonoscopy group" and in the "follow-up group", the sensitivity were 0.81 (95%CI: 0.73-0.87) and 0.88 (95% CI: 0.81-0.92), respectively; the specificity were 0.92 (95% CI: 0.89-0.93) and 0.95 (95% CI: 0.94-0.96), respectively. It was also found that in the qualitative group and the quantitative group, the sensitivity were 0.84 (95% CI: 0.76-0.90) and 0.86 (95% CI: 0.78-0.92), respectively; the specificity were 0.94 (95% CI: 0.91-0.96) and 0.93 (95% CI: 0.91-0.94), respectively.

CONCLUSIONIFOBT had high overall sensitivity and specificity for detecting colorectal cancer.

Objective:To systematically summarize and comparatively analyze the development, establishment and usage of oncology drugs speedy review approaches in China and in the United States between 2012 and 2021.Methods:Based on National Medical Products Administration (NMPA) and Food and Drug Administration (FDA) websites, the development and current status of the speedy review approaches were consulted and summarized. Approved oncology drugs in China and in the United States (87 in China, 118 in the United States) over the past decade were analyzed using chi-square test for group comparison.Results:Five speedy approaches have been established in China and in the United States, three of which are the same, priority review, conditional approval or accelerated approval and breakthrough therapy. The rest two are special review and approval, special examination and approval in China, and fast track and real-time oncology review in the United States. Compared to the United States, speedy review approaches in China set up late (1992 vs. 2005). The overall utilization rates of the oncology drugs speedy review approaches were similar between the China and United States (90.8% vs. 92.4%, P=0.800) in the previous 10 years, and priority review have highest utilization rates in both China and the United States without significant group difference (77.0% vs. 82.2%, P=0.381); relatively low utilization rates of conditional approval (31.0% vs. 44.9%, P=0.041) and breakthrough therapy (2.3% vs. 50.0%, P＜0.001) were seen in China. 52.9% of new drugs applied for special examination and approval in China and 40.7% of new drugs applied for fast track in the United States. Overall, the priority review both in China and the United States are stable, with a similar average annual utilization rate (84.8% vs. 83.7%); accelerated approval and breakthrough therapies in the United States fluctuate wildly, but the situation is tending towards stability in the last 3 years. Conclusions:Both China and the United States have established a relatively complete accelerated review system, with an overall utilization rate over 90%; China's accelerated review started late, although the overall utilization rate is close to that of the United States. The utilization rates of conditional approval and breakthrough therapy are still relatively low. Flexible usage of speedy review approaches, gaining regulatory recognition to use alternative endpoints, achieving real-time review and guidance are keys to accelerate new drug development in China.

Burden of colorectal cancer is rising in China. More attention and financial input have been paid to it by central government that colorectal cancer screening program has been carried out recently in many areas in China. Diversity of screening strategies and limited health resources render selecting the best strategy in a population-wide program a challenging task that economy was also required to be considered except safety and efficacy. To provide a reference for the subsequent further economic evaluation, here we reviewed the evidence available on the economic evaluation of colorectal cancer screening in China. Meanwhile, information related to screening strategies, participation and mid-term efficacy of screening, information and results on economic evaluation were extracted and summarized. Three of the four studies finally included evaluated strategies combining immunochemical fecel occult blood test (iFOBT) with high-risk factor questionnaire as initial screening, colonoscopy as diagnostic screening. There was a consensus regarding the efficacy and effectiveness of screening compared to no screening. Whereas the lack and poor comparability between studies, multi-perspective and multi-phase economic evaluation of colorectal cancer screening is needed, relying on current population-based screening program to conduct a comprehensive cost accounting.

Background and objective Lung cancer is the most common malignancy and screening can decrease the mortality. High quality screening guideline is necessary and important for effective work. Our study is to review and evalu-ate the basic characteristics and methodology quality of the current global lung cancer screening guidelines so as to provide useful information for domestic study in the future.Methods Electronic searches were done in English and Chinese databases including PubMed, the Cochrane Library, Web of Science, Embase, CNKI, CBM, Wanfang, and some cancer offcial websites. Articles were screened according to the predeifned inclusion and exclusion criteria by two researchers. hTe quality of guidelines was assessed by AGREE II.Results At last, a total of 11 guidelines with methodology were included. hTe guidelines were is-sued mainly by USA (81%). Canada and China developed one, respectively. As for quality, the average score in the “Scale and objective” of all guidelines was 80, the average score in the “Participants” was 52, the average score in the “rigorism” was 50, the average score in the “clarity” was 76, the average score in the “application” was 43 and the average score in the “independence”was 59. hTe highest average score was found in 2013 and 2015. Canada guideline had higher quality in six domains. 7 guidelines were evaluated as A level.Conclusion hTe number of clinical guidelines showed an increasing trend. Most guidelines were issued by developed countries with heavy burden. Multi-country contribution to one guideline was another trend. Evidence-based methodology was accepted globally in the guideline development.

Objective To determine the acceptance and willingness to pay for breast cancer screening among populations at high risk of breast cancer in urban China. Methods From 2012 to 2014, a cancer screening program in urban China (CanSPUC) was carried out in 13 provinces. The current survey was conducted among participants who were evaluated as having"high?risk for breast cancer"using a Harvard model (community?based) and then underwent breast mammography or ultrasonography screening procedure (hospital-based). The study mainly focused on their acceptance and willingness to pay under certain self?payment assumption for breast cancer screening. Results A total of 3 049 participants, with a mean age of 52.4±7.0 years, were included. The group aged 45 to 55 years accounted for 50% of the patients, and the median annual income per capita in the recent 5 years was 22 000 (15 000-34 000) Chinese yuan (CNY). Educational level, occupation, and marital status may affect their full acceptance and voluntary payment (P<0.05). Of all the participants, 99% (3 016 participants) could totally or substantially accept the breast cancer screening. When the breast cancer screening was assumed to be conducted every 3 years in the low?cost self?paid context, 85% (2 581 participants) of the participants had the willingness to pay, while only 17% were willing to pay >100 CNY. The remaining 15% of the residents showed no willingness to pay, and the unaffordable expenditure (70%, 438 participants) and unnecessary screening (24%, 112 participants) were the primary considerations. Significant differences in acceptance, willingness to pay, and payment were found among the provinces. Conclusion Almost all high?risk populations for breast cancer could accept breast cancer screening. The willingness to pay was relatively high, but the amount of payment was limited and low.
