RESUMEN
BACKGROUND: Knee osteoarthropathy is one of the most common degenerative joint diseases in the elderly, total knee arthroplasty (TKA) is the most commonly used treatment for end-stage knee osteoarthropathy. Negative emotions such as anxiety have been extensively documented in knee osteoarthropathy patients. AIM: This study aimed to investigate the Emotional Contagion during hospitalization in patients undergoing TKA. METHODS: Eligible subjects were divided into three case groups according to their anxiety states and bed arrangement. All subjects underwent a unilateral, cemented TKA under general anesthesia. Post-operative recovery outcomes including pain, pain behavior and physical function were recorded pre-operation, 1-day, 1 week, 2-weeks, 1-month and 3-months post-operation. RESULTS: A total of 38 subjects were included in the final analysis. Subjects with anxiety had higher Visual Analogue Scale pain scores, PROMIS-Pain Behavior scores than subjects without anxiety in the Contagion Group preoperation (p ≤ .05). Non-anxiety subjects hospitalized in beds physically adjacent to anxiety subjects experienced more severe pain and poorer function (p ≤ .05). After discharge, all clinical outcomes gradually became lower than anxiety subjects in the Contagion Group, reaching levels similar to non-anxiety subjects in the No Contagion Group within 1 month (p>.05). CONCLUSIONS: This study showed that patients with anxiety may have an "Adjacent Bed Effect" on patients with TKA in the adjacent bed, which may be associated with poorer postoperative recovery, including pain and physical function. We speculate this phenomenon can be effectively avoided by the nursing team through accurately assessing psychological status and reasonable bed arrangements in the inpatient assessment phase.

BACKGROUND: Percutaneous kyphoplasty (PKP) is a minimally invasive technique, and effective treatment, for an osteoporotic vertebral compression fracture (OVCF). Residual back pain is the most common complication of PKP. Medial branch block (MBB) is a treatment option for painful OVCF, it can break the vicious cycle to release short- or long-term pain. OBJECTIVES: We aimed to determine the effects of MBB on postoperative residual back pain in OVCF patients after PKP surgery. STUDY DESIGN: A randomized, controlled, single-center trial. SETTING: Medical university center and local hospitals. METHODS: A total of 198 patients were recruited and randomly assigned to either the MBB or Non-MBB group. In the MBB group, patients received MBB during PKP surgery, the injection contained a mixture of lidocaine and budesonide. The Non-MBB group was injected with normal saline in the target nerve area during PKP surgery. The primary outcome was back pain assessed by the Visual Analog Scale (VAS), and residual back pain was defined as a VAS score greater than or equal to 4. The secondary outcomes included physical function assessed by Patient-Reported Outcome Measurement Information System Physical Function (PROMIS PF) and satisfaction with surgery was assessed using the S6 satisfaction scale. All parameters were measured at baseline, 1 day, 1 week, 1 month, 3, 6, and 12 months after the intervention. RESULTS: A total of 179 patients, including 91 patients in the MBB group and 88 patients in the Non-MBB group, were included for a comprehensive assessment. The VAS score in the MBB group was significantly lower than in the Non-MBB group within a one-month follow-up. PROMIS PF score in the MBB group was significantly higher than in the Non-MBB group within a one-month follow-up. The incidence of residual back pain in the MBB group was lower than the Non-MBB group within a one-month follow-up. The MBB group had a significantly higher satisfaction rate compared with the Non-MBB group at final follow-up. LIMITATIONS: Firstly, patients are from a single institution and the sample size is small. Secondly, some of the potential factors which may lead to back pain, such as infection, new symptomatic compression fracture, and serious cement leakage, did not occur. Thirdly, the conservative treatment group is not included. Finally, we were unable to determine individual differences in pain tolerance. CONCLUSIONS: MBB can effectively relieve back pain and reduce the incidence of residual back pain in OVCF patients after PKP surgery. Besides, it can also significantly improve postoperative physical function and patients' satisfaction with treatment.

To study the SSR loci information and develop molecular markers, a total of 43 683 Unigenes in transcriptome of Andrographis paniculata were used to explore SSR. The distribution frequency of SSR and the basic characteristics of repeat motifs were analyzed using MicroSAtellite software, SSR primers were designed by Primer 3.0 software and then validated by PCR. Moreover, the gene function analysis of SSR Unigene was obtained by Blast. The results showed that 14 135 SSR loci were found in the transcriptome of A. paniculata, which distributed in 9 973 Unigenes with a distribution frequency of 32.36%. Di-nucleotide and Tri-nucleotide repeat were the main types, accounted for 75.54% of all SSRs. The repeat motifs of AT/AT and CCG/CGG were the predominant repeat types of Di-nucleotide and Tri-nucleotide, respectively. A total of 4 740 pairs of SSR primers with the potential to produce polymorphism were designed for maker development. Ten pairs of primers in 20 pairs of randomly picked primers produced fragments with expected molecular size. The gene function of Unigenes containing SSR were mostly related to the basic metabolism function of A. paniculata. The SSR markers in transcriptome of A. paniculata show rich type, strong specificity and high potential of polymorphism, which will benefit the candidate gene mining and marker-assisted breeding.

OBJECTIVE: To investigate the reporting characteristics of case reports of acupuncture therapy with CAse Report (CARE) guidelines, and to explore the applicability of the guidelines for these case reports. METHODS: Case reports published from January 1, 2011 to December 31, 2013, were identified by searching PubMed and the China Biomedicine Database by using MeSH terms. Screening and data extraction of case reports were conducted by two independent researchers. Assessments based on CARE guidelines and data analysis were conducted by using Excel 2003 and RevMan 5.0. RESULTS: A total of 61 case reports published in 19 journals were identified, which involved 16 major types of diseases. Fifteen (24.6%) case reports declared no conflict of interests, and 5 (8.2%) reported funding sources. None of these case reports met all items of CARE guidelines, and only 6 subordinate items were fully reported among 50% of the case reports. Subgroup analysis indicated that case reports published in English or those that did not have competing interests had higher reporting quality. CONCLUSIONS: The reporting quality of case reports of acupuncture therapy is rather low. The reason might be a lack of awareness among authors and the poor dissemination of information regarding CARE guidelines in China. More evaluation studies are needed to promote and improve adherence to CARE guidelines. Moreover, an extended version of CARE guidelines should be developed for cases reports of special interventions such as acupuncture or adverse events caused by interventions.

Two-dimensional (2D) gel electrophoresis is the most common protein separation method in proteomics research. It can provide high resolution and high sensitivity. However, 2D gel methods have several limitations, such as labor-intensive procedures, poor reproducibility, and limited dynamic range of detection. In fact, many investigators have returned to couple the one-dimensional (1D) SDS-PAGE with mass spectrometry for protein identification. The limitation of this approach is the increased protein complexity in each one-dimensional gel band. To overcome this problem and provide reproducible quantitative information, we describe here a 2D method for protein mixture separation using a combination of high performance liquid chromatography (HPLC) and 1D SDS-PAGE. The study shows that the step-gradient fractionation method we have applied provides excellent reproducibility. In addition, high mass accuracy of LC-FTICR-MS can allow more confident protein identifications by high resolution and ultra-high mass measurement accuracy. This approach was applied to comparative proteomics since protein abundance level changes can be easily visualized with side-by-side vertical comparison in one gel. Furthermore, separation of multi-samples in the same gel significantly reduces run-to-run variation, as is shown with differential image gel electrophoresis (DIGE). Finally, this approach readily incorporates immunological methods to normalize relative abundances of multiple samples within a single gel. This paper presents the results of our developments and our initial application of this strategy for mapping protease function of beta amyloid cleaving enzyme (BACE) in biological systems.
