Background Hypertension and dyslipidemia are the 2 important risk factors of cardiovascular affecting the prognosis of cardiovascular disease. However paucity data of characteristics of lipid metabolism and prognosis of cardiovascular diseases in high-risk groups with hypertension are available. Objective To analyze the lipid metabolism level and the relevant risk factors of inpatients with essential hypertension (EH) from 2000 to 2007. Methods Retrospective study was performed based on the clinical characteristic and the relationship between different kinds of hyperlipidemia and target organ damages in inpatient with EH. Results For the level of triglyceride (TG) and the prevalence of hypertriglyceridemia,males(n=3056) were significantly higher than females(n=1932)(P

Objective To study the protective effect of glucocorticoid preconditioning on the myocardial ischemic and reperfused hearts.Methods Totally 18 rabbits were randomly divided into three groups: myocardial ischemia-reperfusion model(model),high-dose glucocorticoid given by one time group(high-dose group) and low-dose glucocorticoid given by several times group(low-dose group),with six rabbits in each group.Myocardial ischemia was induced by left anterior descending coronary artery ligation.ST segments were recorded by the BL-420 biological signal acquisition system.Plasma malondial dehyde(MDA) was examined before ischemia,at 15 min after ischemia and 30 min after reperfusion;ischemic heart muscles were prepared with cryotomy and stained histochemically.Succinic dehydrogenase activity was observed in the ischemic region.Results There was shorter time of ST-segment recovery in the high-dose group and the low-dose group than that in the model group.Serum level of MDA in the high-dose group was lower than in the low-dose group(P

Objective:To analyze the clinical manifestations and laboratory features of brucellosis patients in order to provide help for clinical diagnosis.Methods:The medical records of confirmed brucellosis patients ( n=81) in Kunming Third People's Hospital from 2015 to 2019 were collected. The occupation, contact history, clinical manifestations, laboratory examination characteristics and treatment of the patients were retrospectively analyzed. Results:The 81 cases of brucellosis were mainly farmers (64 cases), most of who had a history of raising sheep or contacting sheep manure or secretions (71 cases). The clinical manifestations were fever (68 cases), low back pain (42 cases), joint pain (22 cases), including 72 cases in acute stage and 9 cases in chronic stage. Laboratory examination showed that liver function index total bilirubin (TB) and direct bilirubin (DB) were generally normal, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma glutamyltransferase (GGT) were increased in about half of the patients; high sensitivity C-reactive protein (HsCRP), procalcitonin (PCT), interleukin-6 (IL-6) and serum amyloid A (SAA) were increased in more than 80% of the patients, and erythrocyte sedimentation rate (ESR) was increased in 64.6% (42/65) of the patients. Doxycycline plus rifampicin was the first-line treatment program.Conclusion:The clinical manifestations of patients with brucellosis are diverse and atypical, and patients with nonspecific clinical manifestations such as fever should be combined with their occupation, contact history, indicators of infection detection, timely blood culture examination to make a clear diagnosis, and patients with abnormal liver function should pay attention to asking about occupation and contact history, so as to reduce misdiagnosis and mistreatment of brucellosis.

OBJECTIVETo verify the linkage of the candidate regions identified in a previous study (markers D2S168, D2S151, D2S142 on chromosome 2) with hypertension in Chinese families.

METHODSA genetic linkage study focused on chromosome 2 was performed on 240 Chinese families containing 856 patients with essential hypertension. A total of 1080 individuals were genotyped using 9 highly polymorphic microsatellite markers around the candidate regions on chromosome 2 with an average spacing of 5 cM. Non-parametric linkage (NPL), parametric linkage analysis and transmission-disequilibrium test (TDT) with the GENEHUNTER software were used to assess evidence for linkage.

RESULTSLinkage of a region on chromosome 2 around D2S151 and D2S142 with hypertension was confirmed by different statistical methods (NPL, LOD score and TDT). However, the linkage of D2S168 could not be replicated in this extension study.

CONCLUSIONSThe data suggest that a region on chromosome 2 at or near the loci of D2S142 and D2S151 may harbor genes responsible for the development of essential hypertension in Chinese.

Compared to conventional cancer treatment, combination therapy based on well-designed nanoscale platforms may offer an opportunity to eliminate tumors and reduce recurrence and metastasis. In this study, we prepared multifunctional microspheres loading I-labeled hollow copper sulfide nanoparticles and paclitaxel (I-HCuSNPs-MS-PTX) for imaging and therapeutics of W256/B breast tumors in rats. F-fluordeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) imaging detected that the expansion of the tumor volume was delayed (<0.05) following intra-tumoral (i.t.) injection with I-HCuSNPs-MS-PTX plus near-infrared (NIR) irradiation. The immunohistochemical analysis further confirmed the anti-tumor effect. The single photon emission computed tomography (SPECT)/photoacoustic imaging mediated by I-HCuSNPs-MS-PTX demonstrated that microspheres were mainly distributed in the tumors with a relatively low distribution in other organs. Our results revealed that I-HCuSNPs-MS-PTX offered combined photothermal, chemo- and radio-therapies, eliminating tumors at a relatively low dose, as well as allowing SPECT/CT and photoacoustic imaging monitoring of distribution of the injected agents non-invasively. The copper sulfide-loaded microspheres, I-HCuSNPs-MS-PTX, can serve as a versatile theranostic agent in an orthotopic breast cancer model.
