Objective Pericardiocentesis and drainage are the common measures for the treatment of cardiac temponade and massive pericardial effusion. In this issue, the complications of pericardiocentesis and drainage were discussed. Methods 5 in-hospital cases of cardiac temponade or massive pericardial efiusion who had complications of pericardiocentesis and drainage were reported and analyzed. Results The complications were 2 cases with neural mediated syncope, 1 case with pleural efiusion, 1 case dead of acute right ventricular dilation, and 1 case with acute pulmonary edema and effusion leaking into the subcutaneous tissue. Conclusion The importance of hemodynamic change during pericardiocentesis and drainage could not be over-emphasized, and the patients whose hemodynamic status were unstable should be monitored by bedside hemodynamic monitoring or echocardiography. Also we should pay more attention to the drainage catheter per se, which may cause the complications.

Objective To investigate the characteristics of cerebral vascular imaging and risk factors of stroke in popu?lation with family history of stroke in rural areas of Ji County, Tianjin. Methods The volunteers with family history of stroke were recruited in the study to undergo computed tomography and computed tomography angiography (CTA) of head as well as physical and laboratory examinations. A total of 281 subjects, including 153 male and 128 female, underwent exami?nation, and were divided into stroke group and non-stroke group. Results The detection rates were significantly higher in male subjects than those of female subjects, including smoking rate, drinking rate, educational level, and decreased level of high density lipoprotein cholesterol (HDL-C), whereas the detection rate of high level of triacylglycerol (TG) was significant?ly higher in female than that of male subjects (P<0.05). There were 38 subjects in stroke group. The age, internal carotid ar?tery calcification rate (ICAC) and internal carotid artery tortuosity (ICAT) rate were significantly higher in stroke group than those of non-stroke group (P<0.05) . The results of multivariate Logistic regression analysis indicated that age, hyperten?sion, ICAC, and ICAT were independent risk factors for stroke. Conclusion For population with family history of stroke, age, hypertension, ICAC and ICAT were risk factors of stroke.

Objective The aim of this study was to evaluate whether PRDM16 gene polymorphisms were associated with dyslipidemia. Methods The polymorphisms of rs2651899, rs2236518, rs870171, and rs2282198 in PRDM16 gene in 528 participants were genotyped by the method of snapshot or ligase detection reaction. The genotype differences and the allele differences between the case group and the control group were analyzed. Linkage disequilibrium analysis was performed with SHE-sis online software. The interaction between rs2651899, rs2236518, rs870171, rs2282198 and gender, age, BMI were analyzed by MDR software. Results The frequency of allele A in rs2651899 locus was significantly higher in low HDL-C group compared with that in control group[OR(95%CI)=1.32(1.02-1.71), P=0.033]. The frequency of A/C genotype in rs870171 was significantly different between LDL-C abnormal group and control group[OR(95% CI)=1.97(1.01-3.86), P=0.037]. There may be interaction between rs2236518 and sex, which is a risk factor for low HDL-C[Model Ⅱ: OR(95% CI)=1.958(1.366-2.809), P<0.01]. There may be interactions among rs2651899, rs2236518, rs870171, and rs2282198, which seemed to be risk factors for lower HDL-C[Model Ⅳ: OR(95% CI)=3.991(2.707-5.884), P<0.01]. rs870171, rs2282198 may have interaction with age, which is a risk factor for high LDL-C [Model Ⅶ: OR(95%CI)=3.991(2.707-5.884), P<0.01]. Conclusion Allele A of rs2651899 may be a risk factor to low HDL-C. Under the codominant inheritance patterns, genotype A/C of rs870171 may be a risk factor to high LDL-C. In addition, there may be interaction between SNPs with gender and age.

Objective:To explore the clinical application value of CT-guided methylene blue staining and/or Hookwire localization of pulmonary ground-glass nodule (GGN) before video-assisted thoracoscopic surgery (VATS). Methods: Totally 141 patients with 160 GGN underwent VATS after CT-guided methylene blue staining and/or Hookwire implantation for localization of nodules. The success rate of localization, puncture complications and success rate of surgery were calculated. Results: All GGN were successfully located and resected. Among 160 nodules, 18 were located with stained with methylene blue, 12 with Hookwire implantation, while 130 nodules were located with combination of two methods, and the success rates of methylene blue staining, Hookwire implantation and combination of these two methods were all 100%. Small amount of pulmonary hemorrhage and pneumothorax were observed in 25 and 38 cases respectively during puncture, including 13 cases with both pulmonary hemorrhage and pneumothorax. Postoperative pathology showed that 117 nodules were malignant and 43 were benign nodules. Conclusion: CT-guided methylene blue staining and/or Hookwire implantation before VATS can accurately locate GGN, reduce puncture complications and improve the success rate of resection.
