Surgical treatment of coronal shear fractures of the distal humerus with an intact lateral epicondyle by the lateral combined approach.

Background: Coronal shear fractures of the distal humerus are not only rare and prone to misdiagnosis, but their surgical treatment can be challenging. We aimed to investigate the feasibility of exposing distal humeral coronal shear fractures with a combined lateral approach that preserves the extensors and lateral ulnar collateral ligament (LUCL) and to analyze the clinical efficacy of open reduction and internal fixation in the treatment of these injuries.

Methods: We included 45 patients who sustained coronal shear fractures of the distal humerus with the lateral epicondyle intact and were treated with open reduction and internal fixation from January 2013 to August 2020.

Arthroscopic Medial Bi-portal Extra-articular Debridement for Recalcitrant Medial Epicondylitis.

Medial epicondylitis, or golfer's elbow, is characterized by pain and tenderness at the tendon insertion points of the pronator teres and flexor carpi radialis. Conservative treatment is sufficient for most patients, whereas surgical treatment is the best choice for intractable medial epicondylitis. With open surgery or arthroscopic surgery, good clinical results have been reported.

Catalytic performance and mechanism study of the isomerization of 2,5-dichlorotoluene to 2,4-dichlorotoluene.

This work investigates the influence of catalyst HZSM-5 on the isomerization of 2,5-dichlorotoluene (2,5-DCT) to produce 2,4-dichlorotoluene (2,4-DCT). We observe that hydrothermal treatment leads to a decrease in total acidity and Brønsted/Lewis ratio of HZSM-5 while generating new secondary pores. These characteristics result in excellent selectivity for post-hydrothermal modified HZSM-5 in the isomerization reaction from 2,5-DCT to 2,4-DCT.

Acupuncture for musculoskeletal pain: A meta-analysis and meta-regression of sham-controlled randomized clinical trials.

The aims of this systematic review were to study the analgesic effect of real acupuncture and to explore whether sham acupuncture (SA) type is related to the estimated effect of real acupuncture for musculoskeletal pain. Five databases were searched. The outcome was pain or disability immediately (≤1 week) following an intervention.

Objective: To observe the clinical characteristics of triceps brachii tendon rupture at olecranon ending.

Methods: From June 2005 to November 2011,19 patients with triceps brachii tendon rupture at olecranon ending were treated with surgical technique. Among the 19 patients, 7 patients were male, with an average age of 24.

[Typing and identification of non-polio enterovirus from acute flaccid paralysis cases in Ningxia, 1997-2011].

Objective: To identify the serotype of 73 non-polio enterovirus (NPEV) strains from acute flaccid paralysis (AFP) cases in Ningxia province, during 1997 - 2011.

Methods: Partial sequencing of the VP1 region was amplified by RT-PCR with degenerate primers and sequenced while sequences were compared with the database of GenBank by the BLAST algorithm. Evolution was analyzed by constructing phylogenetic tree using Mega 5.

Improvement of drought and salt tolerance in Arabidopsis and Lotus corniculatus by overexpression of a novel DREB transcription factor from Populus euphratica.

A novel DREB (dehydration-responsive element binding) gene, designated PeDREB2a, was isolated from the desert-grown tree, Populus euphratica Oliv. PeDREB2a is classified into the A-5 group of DREB subfamily based on multiple sequence alignment and phylogenetic characterization. Using semi-quantitative RT-PCR, we found that the PeDREB2a was greatly induced by drought, NaCl, low temperature, 1-naphthaleneacetic acid (NAA), 6-benzyl aminopurine (6-BA) and gibberellic acid (GA3) treatments in P.

[Genetic characteristics of entervirus 71 isolated in Ningxia Hui Autonomous region in 2009].

Objective: To analyze the genetic characteristics of EV71 strains isolated from HFMD cases in Ningxia Hui Autonomous Region in 2009.

Methods: In 2009, totally 385 specimens from 344 HFMD cases were collected from Ningxia. Enterovirus isolation was performed in RD cell line from all the specimens.

Objective: To study the genetic characterization of coxsackievirus A16 (CVA16) strains isolated during an epidemic of hand, foot, and mouth disease (HFMD) in Ningxia Hui Municipality in 2008.

Methods: Clinical samples were collected from HFMD patients in Ningxia Hui Municipality and CVA16 strains were isolated by viral isolation methods. Reverse transcription-polymerase chain reactions (RT-PCR), specific for CVA16 were performed with these CVA16 strains.

[Clinical observation on percutaneous autologous bone marrow grafting for treatment of fracture nonunion].

Objective: To observe the effectiveness of percutaneous bone marrow grafting for treatment of fractures nonunion.

[Secreted expression of nonstructural protein gene 3ABC of foot-and-mouth disease virus in Sf9 cells and activity analysis].

Entire 3ABC sequence of FMDV containing a 6 x his tag coding sequence at the N-terminal was obtained through PCR amplification using a pair of specific primers, subcloned into shuttle plasmid of pMelBac-B with a melittin secretion signal sequence and finally constructed recombinant plasmid of pMel-3ABC. After co-transfected the recombinant plasmid and linearized Bac-N-Blue DNA into Sf9 insect cell under intermediary agent of the Cellfectin, the result showed that we have already acquired recombinant baculovirus by screen of plaque assay and identification of PCR. Though the recombinant baculovirus infecting the Sf9 cells again, experiments indicated that 3ABC gene could express in insect cells and the expressed protein was secreted in the supernatant of Sf9 cell culture possessing favourable biological activities detected by adopting two methods of SDS-PAGE and Western blot.
