ABSTRACT
Objective To observe the effect of Huoxue-Yixin decoction combined with atorvastatin on NT-pro and QTd in patients with chronic heart failure (CHF). Methods A total of 120 patients with chronic heart failure in our hospital from December 2016 to June 2017 were enrolled in this study. The subjects were randomly divided into the control group (n=60) and the treatment group (n=60). The control group were treated with conventional treatment,and the treatment group were treated with Huoxue-Yixin decoction combined with atorvastatin. The two groups were treated for 30 days. The NT-ProBNP, QTd, QTcd and LVESD, LVEDD, LVEF of the two groups before and after treatment were compared.Results The QTd at 2 d(45.6 ± 8.9 ms vs.64.0 ± 18.2 ms,t=-7.029),14 d(44.3 ± 6.8 ms vs.55.7 ± 12.8 ms,t=-6.092)in the experiment group were significantly lower than those of control group(P<0.01).The level of QTcd at 2 d(50.8 ± 10.1 ms vs.71.2 ± 19.8 ms,t=7.109), 14 d(48.1 ± 9.7 ms vs.63.1 ± 13.1 ms,t=7.128)of the experiment group were significantly lower than those of control group(P<0.01).After treatment,the NT-ProBNP(494.58 ± 331.61 ng/L vs.594.71 ± 382.65 ng/L,t=-1.532), LVESD(40.23 ± 3.13 mm vs.49.72 ± 3.99 mm,t=-14.495)and LVEDD(58.22 ± 3.30 mm vs.65.11 ± 3.95 mm, t=-10.720)of the treatment group were significantly lower than those of the control group(P<0.01).The LVEF (69.82% ± 4.72% vs. 50.34% ± 4.02%, t=-10.720) of the treatment group was significantly higher than the control group(P<0.01).Conclusions The Huoxue-Yixin decoction combined with atorvastatin can reduce the level of NT-ProBNP, QTd and QTcd in patients with CHF, can significantly improve cardiac function.
ABSTRACT
The incidence of osteoporotic vertebral fractures (OCVF) has increased year by year.MRI is noninvasive and nonradiative,which can be used to observe the type,pathological stage and severity of OCVF.In recent years,MRI has become an important method to evaluate OCVF,which can provide imaging basis for clinical choice of treatment.The research progresses of MRI in OCVF were reviewed in this article.
ABSTRACT
Objective To investigate th grade of CT in colonic diverticulitis and the value in predicting clinical treatment.Methods CT data of totally 41 patients with colonic diverticulitis were analyzed retrospectively.According to the imaging signs,the grading of diverticulitis cases was performed.Patients with level 1 to 3 were considered as only need non-operative treatment,those with level 4 or 5 were considered as need surgical treatment.The consistency of predictive treatment plans were contrasted with clinical practical treatment results.Results The CT features of colonic diverticulitis were saclike protrusions bulged outside of the bowel wall with colon wall thickening in 40 cases (40/41,97.56％) and fuzzy pericolonal fat space in 39 cases (39/41,97.12％).The diagnostic accuracy of preoperative CT grading in predictive treatment plan was 85.37 ％ (36/41).Conclusion Colonic diverticulitis have certain characteristic CT findings.CT grading of diverticulitis is helpful to formulate appropriate clinical treatment.
ABSTRACT
Objective To evaluate the value of CT Angiography (CTA)in the diagnosis of cerebral aneurysms in patients with a-cute subarachnoid hemorrhage (SAH )with Meta analysis.Methods A systematic search in PubMed,MEDLINE,EMBASE, CNKI,CBM,WANFANG databases was performed.Criteria for inclusion were established based on validity criteria for diagnostic research published by the Cochrane Methods Group on Screening and Diagnostic.The methodological quality of each study was eval-uated by QUADAS.Meta-Disc Version 1.4 software were used for heterogeneity test and the pooled weighted sensitivity,specifici-ty,positive likelihood ratio,negative likelihood ratio and 95% confidence intervals were calculated,receiver operating characteristic (SROC)and area under the curve(AUC)were obtained with random-effects models.Stata12.0 was used for the funnel plot to ana-lyze publication bias.Results Fourteen studies were included with a total of 1 332 patients and 1 149 ruptured cerebral aneurysms. The pooled weighted sensitivity and specificity of CTA with 95% confidence interval was 0.96(0.95-0.97)and 0.99(0.97-1.00) respectively.The AUC and the Q value of SROC was 0.99 and 0.958 4 respectively.Conclusion CTA has high sensitivity and spe-cificity in the diagnosis of cerebral aneurysms in patients with SAH,can be proposed as an important imaging diagnostic method.
ABSTRACT
ObjectiveTo establish rabbit knee joint cartilage injury models to evaluate effects of the type Ⅱ collagen sponge in repair of the articular cartilage.MethodsThe type Ⅱ collagen sponge was prepared according to previous method and the pore size of the sponges was measured based on the collagen autofluorescence characteristics.The type Ⅱ collagen sponge was transplanted into the injury lesions of the animal model for experimental study.The regeneration of the cartilage defects was observed by using MRI, histologic HE staining, Safranin O, sirius red polarized light staining, areas determination of the newly grown cartilage and immunohistochemistry of type Ⅱ collagen.ResultsAutofluorescent images of confocal microscope layer scanning showed that the pore size was (93.26 + 38.40) μm in diameter, suitable for chondrocyte growth.Comparison between MRI and H&E staining results showed quicker effusion absorption in the treatment groups than that in the control group, while the level of inflammatory response in the treatment group was lower than that in the control group.The sporadic cartilage signals first appeared at the 6th week.The newly formed cartilage with the expression of glycosaminoglycan and type Ⅱ collagen matrix was confirmed by Safranin O staining and immunohistochemical analysis.The sirius red polarized light staining showed that areas of the newly formed cartilage were significantly larger in the treatment group than that in the control group (P ＜ 0.01).Conclusion The type Ⅱ collagen sponge developed from purification can effectively repair the damaged cartilage tissues of the rabbit knee joints, as has been verified either by MRI or histology.
