Lower lip recurrent keratoacanthoma: A case report.

Background: This paper introduces a case of recurrent keratoacanthoma (KA). KA is a self-healing disease. Recurrence after surgical resection is rare.

Comparison of transcatheter closure, mini-invasive closure, and open-heart surgical repair for treatment of perimembranous ventricular septal defects in children: A PRISMA-compliant network meta-analysis of randomized and observational studies.

Objective: Our study was aimed to comprehensively compare the relative efficacy, safety, and the cost of transcatheter closure, mini-invasive closure, and open-heart surgical repair to treat perimembranous ventricular septal defects (pmVSDs) in children using network meta-analysis method.

Methods: Five databases were systematically searched including Chinese Biomedical Literature Database, China National Knowledge Infrastructure, PubMed, EMBASE.com, and the Cochrane Central Register of Controlled Trials from the starting date of each database to February 2017.

Transcatheter closure, mini-invasive closure and open-heart surgical repair for treatment of perimembranous ventricular septal defects in children: a protocol for a network meta-analysis.

Introduction: Both transcatheter device closure and surgical repair are effective treatments with excellent midterm outcomes for perimembranous ventricular septal defects (pmVSDs) in children. The mini-invasive periventricular device occlusion technique has become prevalent in research and application, but evidence is limited for the assessment of transcatheter closure, mini-invasive closure and open-heart surgical repair. This study comprehensively compares the efficacy, safety and costs of transcatheter closure, mini-invasive closure and open-heart surgical repair for treatment of pmVSDs in children using Bayesian network meta-analysis.

Effect of statins on blood pressure: Analysis on adverse events released by FDA.

Objective: As a class of cholesterol-lowering drugs, statins have been reported to cause unexpected decrease in blood pressure (BP). However, most studies in this issue were subject to inadequate study design or very small sample size. The present study was designed to examine the BP-lowering effect of various statins.

[Spatio-temporal characteristics of coupling coordination between the quality of population urbanization and land urbanization: The case of 12 central cities in Gansu Province, China].

According to the theory of system science, the paper took 12 central cities in Gansu Province as an example, and respectively built the quality assessment index system of population urbanization and land urbanization on the basis of scientific definition of the quality of population urbanization and land urbanization. Then the coupled coordination model was introduced to calculate the comprehensive development index and coupling coordination degree between quality of population urbanization and land urbanization by the dimension of time and space during 2005-2013. The results showed that population urbanization and land urbanization could only represent the speed of urbanization, it could not measure the quality of urbanization.

[Preliminary study on the value of 99Tc(m)-HL91 imaging in predicting sensitivity to radiotherapy in patients with nasopharyngeal carcinoma].

Objective: To investigate the feasibility of 9Tc(m)-HL91 imaging in prediction of 34 radiotherapy sensitivity of naqsopharyngeal cancer( NPC) and its relationship with prognosis.

Methods: patients with NPC confirmed by pathology, staging from II-IVa, underwent 99Tc(m)-HL91 SPECT imaging one week before radiotherapy. 18 of them received adjuvant chemotherapy.

[Experimental study of differentiation of canine bone marrow mesenchymal stem cell into fibroblasts in vitro].

Objective: To explore the way of stably inducing canine bone marrow mesenchymal stem cells (BMSCs) to differentiate into fibroblasts and myofibroblasts in vitro, and provide seed cells for fabricating tissue engineering heart valves (TEHV).

Methods: Adult canine BMSCs were separated by a gradient centrifugation on Percoll (density 1.073 g/ml), then the cells were incubated in low-glucose Dulbecco Eagle's minimum essential medium (LG-DMEM) with 10% bovine calf serum.

[Effects of modified acellularization process on porcine endogenous retroviruses in porcine aorta valves].

Objective: to study the effect of modified acellularization process on porcine endogenous retrovirus (PERV) in porcine aorta valves (PAVs).

Methods: Twenty aortic valves of pig were put into 0.1% trypsin solution, hypotonic and hypertonic TritonX-100, DNAse solution, RNAse solution, and Hanks solution in succession so as to remove the cells.

[Clinical value of combined therapy with 188Re-HEDP and pamidronate in breast cancer with bone metastasis].

Objective: To evaluate the clinical therapeutic value of (188)Re-HEDP combined with pamidronate in breast cancer with bone metastasis.

Methods: Forty-eight patients with breast cancer with multi-bone metastases were randomly divided into three groups:15 patients received (188)Re-HEDP (group A), 15 patients received pamidronate (group B) and 18 patients were treated by (188)Re-HEDP plus pamidronate (group C).

Results: The overall pain relief rate was 73.
