[Selection of placement position of support points for early and mid-term mechanical repair of femoral head necrosis].

Objective: To investigate the clinical efficacy of the placement of the main mechanical support points in the early and middle stages of mechanical repair of femoral head necrosis in preventing collapse of the femoral head.

Methods: A retrospective analysis was performed for 17 cases 22 hips of non-traumatic femoral head necrosis in the early and middle stages from June 2018 to June 2019, including 14 males 18 hips and 3 females 4 hips, aged 34 to 47 years old. Among them, 6 cases were hormonal, 8 were alcoholic and 3 were idiopathic.

Copper-catalyzed [3+2] annulation of -acyl ketoximes with 2-aryl malonates for the synthesis of 3-aryl-4-pyrrolin-2-ones.

A copper-catalyzed [3+2] annulation of -acyl ketoximes with 2-aryl malonates for the concise synthesis of 3-aryl-4-pyrrolin-2-ones has been developed. The advantage of this method lies in the use of -acyl oximes as an internal oxidant to generate the nucleophilic enamines and electrophilic -quinone methides concurrently. The subsequent nucleophilic addition undergoes selectively on the α-C of malonates.

Copper-Catalyzed Annulation of -Acyl Oximes with Cyclic 1,3-Diones for the Synthesis of 7,8-Dihydroindolizin-5(6)-ones and Cyclohexanone-Fused Furans.

A copper-catalyzed annulation of -acyl oximes with cyclic 1,3-diones has been developed for the concise synthesis of 7,8-dihydroindolizin-5(6)-ones and cyclohexanone-fused furans through the substituent-controlled selective radical coupling process. 2-Alkyl cyclic 1,3-diones undergo C-C radical coupling, while 2-unsubstituted cyclic 1,3-diones undergo C-O radical coupling.

High levels of serum interleukin-6 increase mortality of hepatitis B virus-associated acute-on-chronic liver failure.

Background: Patients with hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF) present a complex and poor prognosis. Systemic inflammation plays an important role in its pathogenesis, and interleukin-6 (IL-6) as a pro-inflammatory cytokine is related with severe liver impairment and also plays a role in promoting liver regeneration. Whether serum IL-6 influences HBV-ACLF prognosis has not been studied.

MiR-96-5p promotes breast cancer migration by activating MEK/ERK signaling.

Background: Breast cancer is the leading cause of cancer deaths in women worldwide. The purpose of the current study was to investigate the potential role of miR-96-5p in breast cancer.

Methods: Breast cancer tissues and matched para-cancerous tissues were collected.

Achillon versus modified minimally invasive repair treatment in acute Achilles tendon rupture.

Purpose: To date, the best treatment of acute Achilles tendon rupture (AATR) is still inconclusive. Achillon seems to be a promising approach with satisfactory function and low complication rate. We hypothesize a modified minimally invasive repair (MMIR), which provides direct visualization of proximal tendon stump without specialized equipment that could provide comparable results.

Characterization of Nucleobases in Broadband Terahertz Spectra from 0.5 to 10 THz with the Air-Biased-Coherent-Detection Technique.

Terahertz time-domain spectroscopy (THz-TDS) is an effective coherent detection technique for deeply understanding the structures and functions of biomolecules. However, generally not full information in the whole THz range can be obtained due to the limited detection bandwidth (usually less than 5 THz) of the traditional THz-TDS systems. In this paper, effective THz absorption spectra in 0.

Association between the concurrence of pre-existing chronic liver disease and worse prognosis in patients with an herb- thunb. induced liver injury: a case-control study from a specialised liver disease center in China.

Objectives: The present study aimed to evaluate the association between the concurrence of pre-existing chronic liver diseases (CLD) and worse prognosis in patients with HILI.

Design: A case-control study.

Setting: Tertiary hospital specialising in liver diseases in China.

[Autogenous femoral head bone grafting combined with total hip arthroplasty for the treatment of old dislocation of hip joint center in 16 cases].

Objective: To study effects of autogenous femoral head bone grafting combined with total hip replacement for the treatment of old center dislocation of hip joint, and to evaluate the superiority of acetabular defect reconstruction with autogenous bone.

Methods: From March 2008 to December 2013, 16 patients (16 hips) with old center dislocation of hip joint were treated with autologous bone graft combined with total hip replacement. There were 11 males and 5 females, ranging in age from 41 to 72 years old, with an average of 56.

Metabolomic Profiling of Autoimmune Hepatitis: The Diagnostic Utility of Nuclear Magnetic Resonance Spectroscopy.

Autoimmune hepatitis (AIH) is often confused with other liver diseases because of their shared nonspecific symptoms and serological and histological overlap. This study compared the plasma metabolomic profiles of patients with AIH, primary biliary cirrhosis (PBC), PBC/AIH overlap syndrome (OS), and drug-induced liver injury (DILI) with those of healthy subjects to identify potential biomarkers of AIH. Metabolomic profiling and biomarker screening were performed using proton nuclear magnetic resonance spectroscopy (H NMR) coupled with a partial least-squares discriminant analysis.
