Objective To investigate effects of early administration of high-dose rosuvastatin(40 mg) on coronary microvascular function and short-term outcome in patients treated with primary percutaneous coronary intervention (PCI) for acute myocardial infarction(AMI). Methods Ninety-four consequent AMI patients treated with primary PCI were divided into rosuvastatin group (50 patients) and control group (44 group). The infarct-related artery flow of epicardium was classified in compliance with the TIMI criteria. Myocardial and microvascular perfusion was assessed using the TMPG. The incidence of the MACE and the cytotoxicity and hepatotoxicity of rosuvastatin was respectively recorded in 30 d follow-up period. Results Either patients in the rosuvastatin group or in the control group showed better TMPG immediately after PCI (P<0.05), compared with that before treatment. However, the post-PCI TMPG of the rosuvastatin group was obviously much better than that of control group (P<0.05). Compared with that in control group, the 30-day composite MACE rate was lower in rosuvastatin group and in the TMPG 3 patients of rosuvastatin group:12.0%(6/50) vs. 34.1%(15/44), P<0.05;11.1%(3/27) vs. 42.9%(6/14). There was no cytotoxicity and hepatotoxicity in two groups. Conclusions Early administration of high-dose rosuvastatin (40 mg) can improve coronary microvascular function and short-term outcome in patients treated with primary PCI for AMI, and it is efficient and safety.

OBJECTIVETo investigate the genome structure variation (SV) related with keloid using the whole-gene resequencing technology.

METHODSWe studied a keloid pedigree containing 4 generation of 27 people. 5 people (4 cases of keloid patients, and 1 case of normal) were selected to extract the genomic DNA. Then the whole-gene resequencing technique was used to check the variations.

RESULTSThrough database comparison and variation annotation analysis, we obtained 2 SVs associated with keloid formation. We used DAVID software to do the gene ontology and pathway analysis. We found a 168 bp inversion in gene tetraspanin 8 (TSPAN8) in all keloid patients, which contained the forth exon of TSPAN8.

CONCLUSIONSThere was no report about SVs related to keloid. In this study, we found 2 SVs associated with keloid, especially TSPAN8. The tumor cells express the TSPAN8 can up-regulate the vascular endothelial growth factor and its receptors, promote the adjacent fibroblasts secrete matrix metalloproteinases and uridylyl phosphate adenosine. So we hypothesis that the inversion of the forth exon in TSPAN8 may lead to the signal transduction disorder in the keloid patients. This study was a preliminary research. It needs a further study containing large sample to confirm.

Objective To study the clinical and genetic characteristics of keloid through investigating on four Han Chinese pedigrees.Methods The pedigree information and clinical data from Han Chinese keloid pedigrees were collected,which consisted of 22 patients in 127 family members,and then the charts of these pedigrees were constructed according to the data.Using the genetic model and pedigree analyses we summarized the clinical features of the disease in the families.Results Four Han Chinese keloid pedigrees were discovered.The three pedigree spans included 3 generations and one was 4 generations.Incidence of KD in the consanguinity family member was 23.7％ (23/93),and 20.8％ (11/53) in male KD,and 27.5％ (11/40) in female.Incidence of anterior chest KD was 40.9 ％.The inheritance pattern observed in these pedigrees was consistent with an autosomal dominant inheritance multi-gene hereditary disease with incomplete penetrance,and its nonpenetrance of KD gene carriers was 12％ (3/25).Conclusions The pattern of inheritance observed in these four Han Chinese keloid pedigrees is similar to previous reports and no gender differences are found in the incidence of disease,but differences in pathogenic site.Pedigree investigation helps to reveal the genetic characteristics of keloid.

ObjectiveTo observe the effect of pulsed electromagnetic fields (PEMFs) on bone mineral density (BMD) of spinal cord injuried (SCI) patients. MethodsThe PEMFs group was composed of 12 SCI patients received regular PEMFs treatment as the treatment group, 12 SCI patients treated without PEMFs were as the control group.BMD of total proximal femur, Ward's trigonum and great trochanter of all patients were detected by dual-energy X-ray absorptiometry before and after treatment.ResultsBMDs of total proximal femur and great trochanter of patients of the treatment group were a little increased after PEMFs treatment, with no significant difference (P>0.05), but BMD change was significantly different compared with the control group (P<0.05～0.01).ConclusionPEMFs treatment along with routine exercise may help to reduce the loss of bone after SCI.

Objectire:To explore and evaluate the predictors for the prognosis of acute besilar artery occlusion(BAO)and the clinical efficacy of intra-arterial thrombolysis and stenting for BAO.Methods:Intra-arterial thrombolysis was administered with recombinant tissue plasminogen activator or urokinase in 52 patients with BAO within 3 to 48 hours.Stenting was performed in patients whose partial recanalization of residual stenosis＞50%after the thrombolysis.National Institutes of Health Stroke Scale(NIHSS)score was measured before the procedure,and the modifled Rankin scale(mRS)score was obtained at 3 months after the procedure.The clinical data were evaluated with the multivariable stepwise logistic regression analysis and Fisher's exact test.Results:Complete recanalization achieved in 24 patients(46.2%),partial recanalization in 16 patients(30.7%),and non-recanalization in 12 patients(23.1%).mRS scores:22 patients(42.3%)had a favorable outcome,32 survived(61.5%),and 20 died (38.5%).The prognosis of BAO was significantly correlated with the NIHSS score(P＜0.01),therapeutic time window (P ＜0.05) and recanalization level (after the thrombolysis and stenting)(P＜0.01 );the good recanalization after the intra-arterial thrombolysis was significantly correlated with the NIHSS score (P ＜0.01) and therapeutic time window (P ＜0.05).Multivariate analysis showed that the NIHSS score ＜ 14 (P ＜ 0.01 ) and good recanalization could independently predict the favorable prognosis of BAO.Conclusions:The NIHSS score ＜ 14 and good recanalization were the independent predictors for good prognosis of BAO.The rapid and timely treatment of BAO with intra-arterial thrombolysis and stenting is a safe and effective measure.

Objective To evaluate the feasibility of precise hepatic segmentectomy or subsegmentectomy using intraoperative image-guided interventional intravascular segmental vessel balloon catheter occlusion of the segmental hepatic artery and portal vein.Methods 6 patients with liver resection carried out from 2011.3-2011.8 were retrospectively analyzed.Results The mean operating time was (270.83±21.31) min,the median of blood loss was 800 ml,the median of intraoperative transfusion volume was 450 ml.The tumors were mainly located in segments Ⅴ,Ⅵ,Ⅶ,Ⅷ.The mean diameter of tumor was (5.67±1.03) cm.Postoperative liver function in the first postoperative day showed the mean alanine aminotranferase (ALT) was (570.00±157.76) U/L,the mean aspirate aminotrarsferase (AST) was (410.00 ±189.94) U/L,and the mean total bilirubin (TBIL) was (10.83± 1.60) mmol/L.Liver function recovered to normal within 7 days.There was intestinal leakage and wound dehiscence in one patient,pleural and effusion in two patients.Conclusion Imageguided interventional intravascular segmental vessel balloon catheter occlusion was a safe and efficacious maneuver.This technique allowed hepatic segmentectomy or subsegmentectomy to be carried out,decreased intraoperative bleeding,and protected the function of the liver remnant.

Objective To explore the utility of cone-beam CT in the evaluation of prostatic arterial embolization (PAE). Methods In a retrospective study, images of DSA and cone-beam CT for PAE in 81 patients with moderate to severe grade benign prostatic hyperplasia were evaluated. In 162 cases of internal iliac arteries (ⅡAs) in 81 patients, images of 6 ⅡAs were excluded due to the technical problems. Therefore, images of 156ⅡAs were included for evaluation. We aim to evaluate the utility of cone-beam CT versus DSA in differentiating PAs and their origins, and demonstrating anastomoses with adjacent arteries. Statistical analyses were performed with Chi-square test to compare the rate of demonstrating vessels between cone-beam CT and DSA. Results One hundred and sixty-one PAs were demonstrated in 156ⅡAs by selective DSA and Cone-beam CT. Cone-beam CT and DSA images demonstrated 158 (98.1%, 158/161) and 130 (80.8%, 130/161) PAs, respectively. The statistical difference was significant (χ2=25.78, P<0.05). PAs were demonstrated by cone-beam CT images alone in 27ⅡAs (17.3%, 27/156) and were demonstrated by DSA images alone in 3ⅡAs (1.9%, 3/161).The statistical difference was significant (χ2=22.31, P<0.05). In 137 PAs that were initially defined by DSA alone, 7 of those (5.1%, 7/137) were eventually proven not to be PAs by further selective cone-beam CT acquisitions. Origins of PAs were shown by Cone-beam CT images alone in 11 ⅡAs. In the remaining 145 ⅡAs (92.9%, 145/156), origins of PAs were shown by both
cone-beam CT and DSA images. The percentage of PA anastomoses demonstrated by cone-beam CT was 42.3%(66/156), which was higher than DSA (31.4%, 49/156). The statistical difference was significant (χ2=3.98, P<0.05). Conclusions Cone-beam CT is useful in demonstrating PAs and their origins fromⅡAs, as well as anastomoses with adjacent arteries.

Objective To evaluate the clinical efficacy and safety of ABO incompatible living kidney transplantation(ABOi-KT). Methods Clinical data of 11 donors and recipients with ABOi-KT were retrospectively analyzed. All the recipients were treated with desensitization before operation. The recovery condition of renal function and blood type antibody titer of the ABOi-KT recipients were monitored after operation. The incidence of complications and clinical prognosis of ABOi-KT recipients were observed. Results The serum creatinine (Scr) of 11 recipients were well recovered after ABOi-KT. No delay in recovery of graft renal function. Among them, 2 recipients experienced a significant increase in the Scr level at postoperative 14 and 45 d respectively, 1 recipient showed criticality cellular rejection after operation and 1 recipient presented with elevated Scr level at postoperative 33 d, accompanied by an increase in blood type antibody titer. The condition became stable after corresponding treatment. The remaining 7 recipients obtained normal graft renal function and postoperative blood type antibody titer did not rebound. During postoperative follow-up until November 2018, no recipient died or graft renal failure occurred. The survival rate of the recipient and graft renal was 100%. Among them, 3 patients suffered from postoperative complications, including pulmonary infection, BK viruria and granulocytopenia, which were cured after symptomatic treatment. Conclusions ABOi-KT is safe, feasible and yields high long-term clinical efficacy, which can increase the source of living donor kidney and relieve the shortage of donor kidney.

The clinical treatment of IgA nephropathy in Traditional Chinese Medicine (TCM) can be treated from theories of Sanjiao, pharynx and kidney, collateral disease and Shaoyang. The Sanjiao theory declaims to clear away damp heat through the whole process of treatment, the upper Jiao lightening the Qi, the middle Jiao clearing away damp heat, and the lower Jiao collecting astringency, strengthening the kidney and cooling blood. The theory of pharynx and kidney focuses on clearing away heat, detoxifying and making benefit of the pharynx, supplemented by tonifying the kidney and strengthening the spleen. In the treatment of collateral diseases, it is considered that the disease is caused by the external invasion of disease pathogens or the damage of the vein caused by the influence of evil Qi. The treatment should be combined with strengthening the right and eliminating evil, and paying attention to promote blood circulation and remove blood stasis. The disease is caused by pooring Qi mechanism of Sanjiao and evil invading Shaoyang. The above TCM systems showed different treatment, but they all improve symptoms, reduce urinary protein quantification, improve quality of life with less adverse events.
