To investigate the CT appearances in early stage of clustering lung paragonimiasis,9 cases of two clustering lung paragonimiasis caused by eating raw stone-crab and laboratory examination were included in the study.Eight cases consulted by doctors in the hospital and their appearances were retrospectively analyzed.There were pleural effusion of varying degree (n=8) and random distribution sub-pleural pulmonary infiltrative lesions (n=7).The accompany appearances of the latter had lunar halo sign,characteristic tunnel sign (n=1) and peri-bronchitis (n=1).If CT detects pulmonary infiltrative lesions of random distribution within sub-pleura or tunnel sign,combining with the history of eating raw stone crabs and other freshwater fishes,with the rise of eosinophilic granulocytes in peripheral blood,the diagnosis of paragonimiasis should be suggested.

Objectives:To evaluate the learning curve of transcatheter aortic valve replacement(TAVR)in a single center by single operator using Venus A valve. Methods:A total of 150 patients with severe aortic stenosis who underwent TAVR using Venus A valve in Fujian Provincial Hospital from July 2018 to May 2022 were selected.According to the time order of TAVR,the 1st-50th patients were included in group A,the 51st-100th patients were included in group B and the 101st-150th patients were included in group C.The basic clinical data,perioperative parameters and postoperative follow-up data of the three groups were analyzed. Results:All high-risk patients with severe aortic stenosis had an average STS score(7.9±1.5)and were treated with Venus A valve.The total operation time of group A,group B and group C was(226.2±86.3)min,(115.2±47.1)min,(108.2±38.1)min;the peripheral path operation time was(45±10)min,(20±7)min,(18±6)min;the valve release time was(13.0±2.3)min,(5.0±2.1)min,(3.0±1.7)min;the X-ray fluoroscopy time was(24±8)min,(11±5)min,(10±3)min;the radiation dose was(1 266±227)mGy,(532±132)mGy,(519±108)mGy;and the total incidence of perioperative adverse events was 46%,18%,16%,respectively.The differences were statistically significant(all P<0.05).The total incidence of adverse events during follow-up within 6 months for patients in group A,group B,and group C were 6%,2%,and 0%(P>0.05).With the increase of TAVR cases,the correlation curve of each time node of TAVR and radiation dose tended to be stable after the 50th-60th cases. Conclusions:With the increase of procedural experience,the total operation time,operative time nodes,radiation dose and perioperative adverse events of TAVR with Venus A valve decreases gradually,and the operator usually needs 50-60 cases to cross the TAVR learning curve.

Objectives:To investigate the effect of body mass index(BMI)on perioperative and long-term prognosis of patients with severe aortic stenosis(AS)after transcatheter aortic valve replacement(TAVR). Methods:This retrospective study imcluded 180 patients with severe AS who received TAVR in Fujian Provincial Hospital from January 2019 to January 2022.According to the BMI,patients were divided into four groups:low weight group(BMI<18.5 kg/m2,n=23),normal weight group(18.5 kg/m2≤BMI<24.0 kg/m2,n=65),overweight group(24.0 kg/m2≤BMI<28.0 kg/m2,n=57),obesity group(BMI≥28.0 kg/m2,n=35).The general clinical characteristics,imaging parameters,perioperative indexes,all-cause death and the incidence of other adverse cardiac events during(18.0±6.8)months follow-up were compared among different groups.Risk factors for the perioperative complications and long-term outcomes of TAVR were evaluated. Results:The prevalence of hypertension and diabetes,left ventricular end-diastolic diameter,ventricular septal thickness and left ventricular posterior wall thickness were significantly higher in the obese group than in normal weight group(all P<0.05).The level of prealbumin in low weight group was lower than in normal weight group(P<0.05).The total perioperative complications in low weight group were higher than in normal weight group(60.9%vs.12.3%,P=0.042).During(18.0±6.8)months follow-up,the incidence of all-cause death in the low weight group was significantly higher than that in normal weight group,overweight group and obese group(17.4%vs.4.6%vs.3.5%vs.5.7%,P=0.003).Kaplan-Meier survival analysis evidenced higher mortality rate in low weight group at 18 months after TAVR(log-rank P<0.01).Multivariate Cox regression analysis showed that the risk of long-term adverse cardiovascular events was significantly higher in low weight group than in normal weight group(HR=7.633,95%CI:1.012-57.564,P=0.049). Conclusions:Low weight patients with severe AS have a higher incidence of perioperative complications and a poor long-term prognosis.Such patients should appropriately strengthen their nutritional intake and adjust their body weight to normal levels before performing TAVR.

Globally, colorectal cancer (CRC) is a substantial public health burden, and it is increasingly affecting populations in Asian countries. The overall prevalence of CRC is reported to be low in Asia when compared with that in Western nations, yet it had the highest number of prevalent cases. This review described the prevalence of CRC in Asia according to the International Agency for Research on Cancer from World Health Organization (WHO) database and summarized its major risk factors. Non-modifiable factors include genetic factors, ethnicity, age, gender, family history and body height; smoking, alcohol drinking, weight, Westernized diet, physical inactivity, chronic diseases and microbiota were involved in environmental factors. These risk factors were separately discussed in this review according to published literature from Asian countries. CRC screening has been playing an important role in reducing its disease burden. Some recommendations on its screening practices have been formulated in guidelines for Asia Pacific countries.

Objective To investigate the CT features of early infection stage of thoracic and pulmonary paragonimiasis. Methods Medical records of 56 patients with thoracic and pulmonary paragonimiasis from January 2010 to June 2017 were collected, and the patients were diagnosed and treated at Yongjia County People's Hospital, and the results of laboratory examination and CT imaging features were analyzed retrospectively. Results The absolute value of eosinophils in peripheral blood of 56 patients was (5.61 ± 3.18) × 109/L, and the percentage of eosinophils was (35.90 ± 19.16)％, all of which increased to varying degrees. Forty-two patients had different degrees of pleural effusion and 52 cases with lung lesions. Lung lesions demonstrated one or several kinds of foci at the same time, randomly distributed in the lung field, mostly located in the sub-pleural lung tissue. There were 12 cases with pulmonary ground glass shadow, 4 cases with peribronchitis, 31 cases with pulmonary invasive lesions and 28 cases with pulmonary nodular/strip shadow. The size of most nodules were 0.5 - 1.0 cm, accompanied with halo sign. Conclusions The CT features of early infection stage of thoracic and pulmonary paragonimiasis are diverse. The size of 0.5 - 1.0 cm lung nodules with halo sign has certain characteristics in the diagnosis of paragonimiasis. Peribronchitis, infiltrative lesions, pleural effusion and increased peripheral blood eosinophil percentage can suggest diagnosis.
