Background::The association and its population heterogeneities between low-density lipoprotein cholesterol (LDL-C) and all-cause and cardiovascular mortality remain unknown. We aimed to examine the dose-dependent associations of LDL-C levels with specific types of cardiovascular disease (CVD) mortality and heterogeneities in the associations among different population subgroups.Methods::A total of 2,968,462 participants aged 35-75 years from China Health Evaluation And risk Reduction through nationwide Teamwork (ChinaHEART) (2014-2019) were included. Cox proportional hazard models and Fine-Gray subdistribution hazard models were used to estimate associations between LDL-C categories (<70.0, 70.0-99.9, 100.0-129.9 [reference group], 130.0-159.9, 160.0-189.9, and ≥190.0 mg/dL) and all-cause and cause-specific mortality.Results::During a median follow-up of 3.7 years, 57,391 and 23,241 deaths from all-cause and overall CVD were documented. We observed J-shaped associations between LDL-C and death from all-cause, overall CVD, coronary heart disease (CHD), and ischemic stroke, and an L-shaped association between LDL-C and hemorrhagic stroke (HS) mortality ( P for non-linearity <0.001). Compared with the reference group (100.0-129.9 mg/dL), very low LDL-C levels (<70.0 mg/dL) were significantly associated with increased risk of overall CVD (hazard ratio [HR]: 1.10, 95% confidence interval [CI]: 1.06-1.14) and HS mortality (HR: 1.37, 95% CI: 1.29-1.45). Very high LDL-C levels (≥190.0 mg/dL) were associated with increased risk of overall CVD (HR: 1.51, 95% CI: 1.40-1.62) and CHD mortality (HR: 2.08, 95% CI: 1.92-2.24). The stronger associations of very low LDL-C with risk of CVD mortality were observed in individuals with older age, low or normal body mass index, low or moderate 10-year atherosclerotic CVD risk, and those without diagnosed CVD or taking statins. Stronger associations between very high LDL-C levels and all-cause and CVD mortality were observed in younger people. Conclusions::People with very low LDL-C had a higher risk of all-cause, CVD, and HS mortality; those with very high LDL-C had a higher risk of all-cause, CVD, and CHD mortality. On the basis of our findings, comprehensive health assessment is needed to evaluate cardiovascular risk and implement appropriate lipid-lowering therapy for people with very low LDL-C.

Objective:To evaluate the efficacy and safety of Tyrosine Kinase Inhibitors (TKIs) combined with stereotactic body radiation therapy(SBRT) in the treatment of renal cell carcinoma (RCC) patients with bone metastasis.Methods:The clinical data of 80 RCC patients with bone metastasis in Sun Yat-sen University Cancer Center from April 2010 to April 2020 were analyzed retrospectively. Among them, 64 patients were medium or high risk according to the International Metastatic Renal Cell Carcinoma Database Consortium(IMDC) score. Twenty-four patients received TKI therapy alone(Group A), and the other 56 cases received TKIs combined with SBRT to bone metastastic lesions (Group B).Results:The median follow-up period was 20.7 months (4.8-115.6 months), 70 patients received second or third-line targeted drug therapy, and 4 patients in group A and 15 patients in group B received TKI plus immunotherapy. Fifty-four patients had symptoms of bone pain before radiotherapy, 46 patients were satisfied with the analgesic effect after SBRT treatment. Twelve patients got complete response (CR) after bone lesions, and 32 patients achieved partial response (PR). Forty patients died of disease progression during follow-up. The median OS was: 20.7 months vs not reached(Group A vs. Group B), and the 2-y OS and 5-y OS were 50% vs. 62%, and 19% vs. 56%, respectively ( P=0.006). There were only 2 patients (3.6%) had grade 3 SBRT related adverse events. Conclusions:SBRT combined with TKIs improved the quality of life and prolonged the overall survival of RCC patients with bone metastasis.

OBJECTIVE: To explore the cause of inconsistent genotypes for an α-thalassemia carrier by using two commercial genotyping kits. METHODS: GAP-PCR and PCR-reverse dot blotting (PCR-RDB) were employed to determine the genotype of the carrier, while Sanger sequencing was used to verify the results. RESULTS: Sequencing analysis demonstrated that the subject has carried a α1 globin gene with a 3.7 kb heterozygous deletion. In addition, two novel mutations, IVS-II-55(T>G) and IVS-II-119(G>TCGGCCC), were found in intron 2 of α2 globin gene. CONCLUSION The two mutations located in the binding regions of PCR primers have caused failure of PCR amplification and misreading of the genotype. Combination of clinical and hematological phenotypes is indispensible to infer the genotype of carriers for accurate diagnosis.

We sought to explore the feasibility of global area strain to assess left ventricular global systolic function in patients with essential hypertension and normal ventricular geometry. Thirty-five essential hypertensive patients with normal ventricular geometry and 30 normally healthy persons as controls were enrolled in this study. The two groups were comparable for age, sex ratio, height, weight, body mass index (BMI), and heart rate. Blood pressures (BPs) were significantly higher in the hypertension group than the control group. Two-dimensional echocardiography and three-dimensional speckle tracking imaging were performed. Left ventricular global area strain (GAS), global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), LV volumes, ejection fraction (EF), sphericity index (SPI), left ventricular end-diastolic and end-systolic mass (EDmass and ESmass) and LV mass index (EDmassI and ESmassI) were obtained. Compared with those of the controls, GAS, GLS, GCS, GRS were significantly reduced in hypertensive patients Call P < 0.001). GAS (r = 0.672, P < 0. 001), GLS (r = 0.587, P < 0.001), GCS (r = 0.639, P < 0.001) and GRS (r = 0.685, P < 0.001) were correlated with EF in the pooled population. GAS showed an excellent correlation with GCS (r = 0.905, P < 0.001), GLS (r = 0.892, P < 0.001) and GRS (r = 0.990, P < 0.001). EF measured with 3D-STI was significantly lower in group of hypertension (P < 0.001) than that in the controls. There were no significant differences between the two groups in cardiac output, sphericity index, EDmass and ESmass, LV mass index (EDmassI and ESmassI) calculated with 3D-STI. The study showed that GAS could identify early changes of left ventricular global systolic function in hypertensive patients with normal ventricular geometry.
