ObjectiveTo analyze the burden and incidence of thyroid cancer in the world and in China based on the 2018, 2020 and 2022 editions of the Global Cancer Statistical Report jointly compiled by the World Health Organization (IARC) and the American Cancer Society. MethodsThe global cancer registry data of GLOBOCAN in 2018, 2020 and 2022 were compiled and analyzed, and the crude and age-standardized rates of thyroid cancer incidence in the world and China were extracted, and the incidence characteristics of thyroid cancer in the world and China were compared. ResultsIn 2022, the number of new thyroid cancers in the world was estimated to be about 821 000, ranking 7th among all cancers, with a crude incidence rate of 10.4 per 100 000. The number of new cases of thyroid cancer in China will be about 466 000, ranking third, with a crude incidence rate of 33.0 per 100 000. There are significant differences in the incidence of thyroid cancer among different genders: in 2022, the number of new cases of thyroid cancer in women is about three times that of men, and the crude incidence rate in women is significantly higher than that in men. From 2018 to 2022, the incidence of thyroid cancer increased year by year in the world and China. ConclusionsThe disease burden of thyroid cancer in China is still heavy and higher than the global level, and the prevention and treatment of thyroid cancer is still facing great challenges.
Objective To provide basis to improve the ability of primary care services in Chengdu by comparatively analyzing inpatient medical service of primary medical institutions (community health service centers and township health centers). Methods From October to November 2016, the data of inpatient services in primary medical institutions in Chengdu, including 390 primary medical institutions in 22 districts (cities) and counties, were investigated by questionnaire. SPSS 19.0 was used for data collection and analysis, while the univariate logistic regression and multiple logistic regression were used to analyze the influencing factors. Results It was more common for rural primary medical institutions to carry out inpatient medical services than urban (96.18% vs. 53.84%). The coverage rate of insurance in urban areas was higher than rural areas (98.41% vs. 90.87%), while the rate of adopting clinical pathway of single disease was quite low both in urban areas (23.81%) and rural areas (18.25%). Primary medical institutions in urban areas launched more special projects of inpatient services than those in rural areas (14.29%–17.46% vs. 3.57%–7.54%). The total amount of inpatient medical services in 2015 in rural areas was larger than urban areas (529 611 vs. 103 912), the total number of inpatient services in rural was 5.09 times that in urban primary medical institutions, the average inpatient services in 2015 per one rural primary medical institution was 1.27 times that in urban, per 10 000 residents in rural areas consumed 3.01 times more inpatient medical services than those in urban areas in average, the median beds utilization efficiency in rural areas was better than in urban areas (74.47% vs. 22.47%); work intensity of inpatient medical service in rural areas was greater than in urban areas (234.57 vs. 81.74 cases per year per doctor). The number of inpatient services was positively related to population in service (when less than 100 000 residents), inpatient beds, the number of drugs, the number of medical staff. Conclusions For inpatient medical service, there are obvious differences between urban and rural areas in Chengdu. Therefore, above differences should be taken into full consideration in the allocation of resources in primary medical institutions. Thus more targeted management measures should be formulated.

ObjectivesTo systematically review the value of cross-linked carboxy-terminal telopeptide of type I collagen (ICTP) in the diagnosis of bone metastases of lung cancer.MethodsThe Cochrane Library, PubMed, EMbase, WanFang Data and CBM databases were electronically searched to collect studies on ICTP in the diagnosis of lung cancer bone metastases from inception to November 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies by QUADAS-2 standard. Meta-analysis was performed by using Meta-Disc 1.4 software.ResultsA total of 8 studies involving 781 patients were included. The results of meta-analysis showed that the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnosis odds ratio and area under the curve of summary receiver operating characteristics were 71% (95%CI 0.65 to 0.76), 80% (95%CI 0.76 to 0.84), 3.79 (95%CI 2.31 to 6.21), 0.35 (95%CI 0.25 to 0.49), 14.67 (95%CI 6.99 to 30.81) and 0.860 3, respectively.ConclusionsICTP cooperate with imaging tests may be accurate and practical in diagnosis of bone metastases of lung cancer. Due to the limited quality and quantity of included studies, the above results should be validated by more studies.
Stroke is one feared complication after transcatheter aortic valve replacement (TAVR). It affects the prognosis of TAVR, leading to a decline in the survival rate and quality of life of patients, while increasing the economic burden of patients. In recent years, a variety of cerebral embolic protection devices have been used to reduce the incidence of stroke during TAVR and improve the prognosis, some of which have been approved for clinical use. However, there are many controversies about their safety and effectiveness. This article reviews the definitions, short-term and long-term incidences, and risk factors of TAVR-related stroke, and elaborates on recent large-scale studies of different cerebral embolic protection devices.
ObjectiveTo explore the preoperative evaluation result of multidetector computed tomography (MDCT) in aortic stenosis (AS) patients with bicuspid aortic valve (BAV) undergoing transcatheter aortic valve replacement (TAVR) in order to summarize relevant experience.MethodsA total of 33 consecutive AS patients who underwent TAVR in Department of Cardiology, First Affiliated Hospital of Xinjiang Medical University from March 2016 to June 2020 were enrolled, and the preoperative evaluation characteristics of MDCT were compared between tricuspid aortic valve (TAV) and BAV.ResultsIn the 33 patients, whose mean age was (74±6) years, 22 were male and 11 were female, 17 were with BAV and 16 were with TAV. The medium (lower quartile, upper quartile) of calcification score was 360 (192, 1 034) mm3. There were 12 cases of artificial valve model to be speculated Downsize, including 9 calcific BAV cases (75%).ConclusionThe calcific BAV has a higher ratio of Downsize in the TAVR procedure.
Objective To investigate the effectiveness of the suture anchor technique without knots for reconstruction of the anterior talofibular ligament (ATFL) combined with the reinforcement of the inferior extensor retinaculum in treating chronic lateral ankle instability (CLAI). Methods The clinical data of 31 patients with CLAI who were admitted between August 2017 and December 2023 and met the selection criteria were retrospectively analyzed. There were 18 males and 13 females, with an age range from 20 to 48 years (mean, 34.6 years). All patients had a history of repeated ankle sprain, with a disease duration of 6-18 months (mean, 9.65 months). The anterior drawer test and inversion stress test were positive, and tenderness was present in the ligament area. Stress X-ray films of the ankle joint showed a talar tilt angle of (10.00±2.78)° and an anterior talar displacement of (9.48±1.96) mm on the affected side. MRI revealed discontinuity, tortuosity, or disappearance of the ATFL structure. Preoperatively, the visual analogue scale (VAS) score was 5.2±2.1, and the American Orthopaedic Foot and Ankle Society (AOFAS) score was 62.9±7.1. All patients underwent arthroscopic debridement of the ankle joint followed by reconstruction of the ATFL using the suture anchor technique without knots combined with reinforcement of the inferior extensor retinaculum. Postoperatively, pain and function were assessed using the VAS and AOFAS scores. Stress X-ray films were taken to measure the talar tilt angle and anterior talar displacement to evaluate changes in ankle joint stability. Patient satisfaction was assessed according to the Insall criteria. Results All 31 surgeries were successfully completed. One case had wound exudation, while the remaining surgical incisions healed by first intention. Two cases experienced numbness on the lateral aspect of the foot, which disappeared within 1 month after operation. All patients were followed up 15-84 months (mean, 47.2 months). No complication such as anchor loosening, recurrent lateral ankle instability, superficial peroneal nerve injury, rejection reaction, or wound infection occurred postoperatively. The anterior drawer test and inversion stress test were negative at 3 months after operation. Stress X-ray films taken at 3 months after operation showed the talar tilt angle of (2.86±1.72)° and the anterior talar displacement of (2.97±1.32) mm, both of which were significantly different from the preoperative values (t=12.218, P<0.001; t=15.367, P<0.001). At last follow-up, 2 patients had ankle swelling after exercise, which resolved spontaneously with rest; all 31 patients returned to their pre-injury level of sports or had no significant discomfort in daily activities. At last follow-up, 25 patients were pain-free, 4 had mild pain after exercise, and 2 had mild pain after walking more than 2 000 meters. The VAS score was 0.8±0.9 and the AOFAS score was 91.6±4.1, both of which were significantly different from the preoperative scores (t=10.851, P<0.001; t=−19.514, P<0.001). According to the Insall criteria, 24 patients were rated as excellent, 4 as good, and 3 as fair, with a satisfaction rate of 90.3%. Conclusion The suture anchor technique without knots for reconstruction of the ATFL combined with reinforcement of the inferior extensor retinaculum provides satisfactory short- and mid-term effectiveness in treating CLAI.
Severe symptomatic native aortic regurgitation (AR) is associated with poor prognosis. Surgical aortic valve replacement is presently the main choice of treatment according to current guidelines. The data of safety and efficacy of transcatheter aortic valve replacement (TAVR) for patients with pure native AR were limited. In this paper, a case of AR patient with heart failure was reported. After preoperative CT evaluation and operation plan, the postoperative symptoms improved significantly. Bundle branch block and retroperitoneal hematoma appeared during hospitalization. After the treatment, the patient’s condition improved. Before the discharge, cardiac ultrasound indicated that the reflux was significantly improved, no perivalvular leakage was observed, and cardiac function was improved. AR remains a challenging pathology for TAVR. TAVR is a feasible and reasonable option for carefully selected patients with pure AR.
It has been 20 years since the first transcatheter aortic valve replacement (TAVR) was performed internationally in 2002, and the development of TAVR technology in China has also been more than 10 years. The reliability of TAVR has been clinically proven, and it has also brought good benefits to patients with aortic stenosis. With the gradual progress of technology, TAVR has a trend to surpass surgical aortic valve replacement and become the mainstream surgery for patients with aortic stenosis. This article will review the relevant issues in the development of TAVR technology in recent years, based on existing research, and provide certain clinical references for the future development of TAVR technology.
