[Comparing hydroxyapatite coated versus non hydroxyapatite coated femoral stems in primary total hip arthroplasty: a meta analysis of randomized controlled trial].

Objective: To evaluate the difference of clinical outcomes and radiological outcomes through meta-analysis on the total hip arthroplasty (THA) between hydroxyapatite(HA) coating and non-HA coating femoral stems.

Methods: We searched the MEDLINE, Embase, Cochrane library and CBM for published randomized controlled trial (RCT) comparing HA coating and non-HA coating femoral stems in primary THA clinical outcomes with Harris hip score and incidence postoperative thigh pain, radiological outcomes with presence of endosteal condensation and radioactive line on the prothesis, heterotopic ossification. Data analysis were performed using RevMan 5.

Hydroxyapatite-coated femoral stems in primary total hip arthroplasty: a meta-analysis of randomized controlled trials.

Background: Controversy exists over the use of hydroxyapatite (HA)-coated femoral stems in primary total hip arthroplasty (THA). We conducted a meta-analysis of randomized controlled trials (RCT) to compare the clinical and radiologic outcomes of primary THA using HA-coated versus non-HA-coated femoral stems.

Methods: Databases including MEDLINE, EMBASE and the Cochrane Library were searched to find relevant RCTs comparing HA-coated versus non-HA-coated femoral stems in primary THA.

A systematic review of randomized controlled clinical trials comparing hamstring autografts versus bone-patellar tendon-bone autografts for the reconstruction of the anterior cruciate ligament.

Objectives: Controversies exist over which type of graft is best for the reconstruction of the anterior cruciate ligament (ACL). The purpose of this systematic review was to evaluate the effectiveness of ACL reconstruction using either hamstring (HT) autografts or bone-patellar tendon-bone (BPTB) autografts.

Methods: We searched the Cochrane Library, MEDLINE and EMBASE for published randomized controlled trials (RCT) comparing HT autografts with BPTB autografts for ACL reconstruction.

Response surface methodology to optimize enzymatic preparation of Deapio-Platycodin D and Platycodin D from Radix Platycodi.

In the present work, we reported the enzymatic preparation of deapio-platycodin D (dPD) and platycodin D (PD) optimized by response surface methodology (RSM) from Radix Platycodi. During investigation of the hydrolysis of crude platycosides by various glycoside hydrolases, snailase showed a strong ability to transform deapio-platycoside E (dPE) and platycoside E (PE) into dPD and PD with 100% conversion. RSM was used to optimize the effects of the reaction temperature (35-45 °C), enzyme load (5-20%), and reaction time (4-24 h) on the conversion process.

Clinical and pathologic comparison of simple left-to-right shunt congenital heart disease and transposition of the great arteries with ventricular septal defect.

Background: This study aimed to compare clinical and pathologic data for selected patients with congenital heart disease (CHD) and severe pulmonary hypertension (PH) treated with a diagnostic-treatment-and-repair strategy and to compare results for patients with pulmonary vascular disease (PVD) with simple left-to-right shunt CHD with patients with transposition of the great arteries (TGA) and ventricular septal defect (VSD).

Methods: Group I comprised 38 patients with simple left-to-right shunt CHD and severe PH; group II included 11 older patients with TGA with VSD and severe PH; and group III comprised 6 autopsy cases of individuals with a normal circulation. The nature of the pulmonary arteries was determined by the Heath-Edwards classification system.

Fast and sensitive LC-DAD-ESI/MS method for analysis of saikosaponins c, a, and d from the roots of Bupleurum Falcatum (Sandaochaihu).

In the present study, we developed a liquid chromatography-diode array detector-electrospray ionization/mass spectrometric (LC-DAD-ESI/MS) method for analysis of saikosaponins in Bupleurum falcatum. The LC method employed a ZORBAX SB-Aq analytical column (150 x 4.6 mm i.

Systematic review of patellar resurfacing in total knee arthroplasty.

Controversies existing over resurfacing the patella in total knee arthroplasty remain in the literature. The purpose of this review was to evaluate the effectiveness of resurfacing versus nonresurfacing the patella in total knee arthroplasty. We searched the Cochrane Library, MEDLINE and EMBASE for published randomised clinical trials relevant to patellar resurfacing.

Attenuation of portal hypertension by natural taurine in rats with liver cirrhosis.

Aim: To investigate the inhibitory effect of natural taurine (NTau) on portal hypertension (PHT) in rats with experimentally-induced liver cirrhosis (LC).

Methods: Experimentally-induced LC Wistar rats (20 rats/group) were treated with either oral saline or oral NTau for 6 consecutive weeks. Evaluation parameters included portal venous pressure (PVP), portal venous resistance (PVR), portal venous flow (PVF), splanchnic vascular resistance (SVR) and mean arterial pressure (MAP).

Bis(triphenyl-stann-yl) thio-phene-2,5-dicarboxyl-ate.

Mol-ecules of the title compound, [Sn(2)(C(6)H(5))(6)(C(6)H(2)O(4)S)], lie on inversion centres with the central thio-phene ring disordered equally over two orientations. The carboxyl-ate groups are approximately coplanar with the thio-phene ring [dihedral angle = 4.0 (1)°] and the Sn-O bond distance of 2.
