Background:
Gout is the most prevalent form of inflammatory arthritis in the world. Total hip arthroplasty (THA) has emerged as a widely sought-after and highly effective surgical procedure for advanced hip diseases. However, there is a lack of research on the impact of gout on primary THA outcomes in large cohorts. This study aimed to address this gap by primarily investigating complications following THA in patients with or without gout.
Methods:
Patients with records of gout in the 2 years leading up to their primary THA and who also have at least 2 years of follow-up were identified using a national insurance database and compared to a 5:1 matched control. A total of 32,466 patients with gout and 161,514 patients without gout undergoing THA were identified. Multivariable logistic regression analyses were done for medical complications up to 90 days and surgical complications up to 2 years. In addition, 90-day emergency department (ED) visits and inpatient readmission were also documented.
Results:
Patients with gout demonstrated higher rates of medical complications including deep vein thrombosis, transfusion, acute kidney injury, and urinary tract infection than non-gout patients (p < 0.001). Gout patients also showed higher rates of pulmonary embolism (p = 0.017). Increased incidences of surgical complications were identified in gout patients, specifically wound complications and periprosthetic joint infection (p < 0.001). There was an increased risk of revision for gout patients up to 90 days (p = 0.003), 1 year (p = 0.027), and 2 years (p = 0.039). There was also an increased risk of dislocation for gout patients up to 90 days (p = 0.022) and 1 year (p = 0.047), but not at 2 years. No significant difference was observed in aseptic loosening or periprosthetic fracture. Additionally, gout patients also demonstrated a higher likelihood of 90-day ED visits and readmission (p < 0.001).
Conclusions
Primary THA in gout patients is associated with increased risks of multiple medical and surgical complications. Our findings provide insights into the planning and expectation of THA for patients with gout. These insights have the potential to benefit the decision-making process for gout patients considering THA.

OBJECTIVE To investigate the improvement effects and mechanism of imperatorin on cachexia model mice. METHODS Fifteen male C57BL/6J mice were randomly divided into blank control group, model group and imperatorin group, with 5 mice in each group. Except for blank control group, the remaining mice were inoculated with LLC cell suspension subcutaneously on the dorsal surface, and the drug was administered by gavage daily from the 7th day of inoculation. The imperatorin group was gavaged with imperatorin suspension (0.5% sodium carboxymethylcellulose solution as solvent) at 60 mg/kg; blank control group and model group were given an equal volume of 0.5% sodium carboxymethylcellulose solution, for 13 d of continuous administration. During the administration period, food intake and body mass of mice were recorded daily and regularly, tumor long and short diameters were measured every two days, and tumor volume was calculated. The skeletal muscle mass and tumor mass of each group were weighed and the tumor-free body weight was calculated; the pathological changes of skeletal muscle were observed and the cross-sectional area of skeletal muscle fibers was calculated; the phosphorylation levels of signal transduction and activator of transcription 3 (STAT3) (measured as p-STAT3/STAT3 ratio), muscle atrophy box F gene (MAFbx), myostatin (Myog), B-cell lymphoma-2 (Bcl-2), Bcl-2 associated X protein (Bax), Caspase3 protein and mRNA expression were all detected. RESULTS Compared with blank control group, body mass and skeletal muscle mass of model group were decreased significantly (P<0.05), and reduced food intake, loose arrangement of skeletal muscle, large cell space were observed; the cross-sectional area of skeletal muscle fiber was significantly reduced, while p-STAT3/STAT3 ratio, protein and mRNA expressions of MAFbx, Bax and Caspase3 were somo_amour@163.com increased significantly (P<0.05). The protein and mRNA expressions of Myog and Bcl-2 were significantly reduced (P< 0.05). Compared with model group, body weight, tumor-free weight and skeletal muscle weight were increased significantly in imperatorin group (P<0.05); food intake increased, while the expressions of tumor weight and volume were decreased significantly (P<0.05); the expressions of above proteins and genes were improved significantly (P<0.05). CONCLUSIONS Imperatorin can improve the tumor cachexia state, the mechanism of which may be related to the regulation of ubiquitin-proteasome pathway and anti-apoptosis.

PURPOSE: Lung adenocarcinoma (LA) is one of the major types of lung cancer. MicroRNAs (miRNAs) play an essential role in regulating responses of natural killer (NK) cells to cancer malignancy. However, the mechanism of miR-218-5p involved in the killing effect of NK cells to LA cells remains poorly understood. MATERIALS AND METHODS: The expression of miR-218-5p was examined by quantitative real-time polymerase chain reaction (qRT-PCR). Serine hydroxymethyl transferase 1 (SHMT1) level was detected by qRT-PCR or western blots. Cytokines production of interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) were detected by ELISA. The killing effect of NK cells to LA cells was investigated using lactate dehydrogenase cytotoxicity assay kit. The interaction of miR-218-5p and SHMT1 was probed by luciferase activity assay. Xenograft model was established to investigate the killing effect of NK cells in vivo. RESULTS: miR-218-5p was enhanced and SHMT1 was inhibited in NK cells of LA patients, whereas stimulation of interleukin-2 (IL-2) reversed their abundances. Addition of miR-218-5p reduced IL-2-induced cytokines expression and cytotoxicity in NK-92 against LA cells. Moreover, SHMT1 was negatively regulated by miR-218-5p and attenuated miR-218-5p-mediated effect on cytotoxicity, IFN-γ and TNF-α secretion in IL-2-activated NK cells. In addition, miR-218-5p exhaustion inhibited tumor growth by promoting killing effect of NK cells. CONCLUSION: miR-218-5p suppresses the killing effect of NK cells to LA cells by targeting SHMT1, providing a potential target for LA treatment by ameliorating NK cells function.

Mitochondrial diseases are maternally inherited heterogeneous disorders that are primarily caused by mitochondrial DNA (mtDNA) mutations. Depending on the ratio of mutant to wild-type mtDNA, known as heteroplasmy, mitochondrial defects can result in a wide spectrum of clinical manifestations. Mitochondria-targeted endonucleases provide an alternative avenue for treating mitochondrial disorders via targeted destruction of the mutant mtDNA and induction of heteroplasmic shifting. Here, we generated mitochondrial disease patient-specific induced pluripotent stem cells (MiPSCs) that harbored a high proportion of m.3243A>G mtDNA mutations and caused mitochondrial encephalomyopathy and stroke-like episodes (MELAS). We engineered mitochondrial-targeted transcription activator-like effector nucleases (mitoTALENs) and successfully eliminated the m.3243A>G mutation in MiPSCs. Off-target mutagenesis was not detected in the targeted MiPSC clones. Utilizing a dual fluorescence iPSC reporter cell line expressing a 3243G mutant mtDNA sequence in the nuclear genome, mitoTALENs displayed a significantly limited ability to target the nuclear genome compared with nuclear-localized TALENs. Moreover, genetically rescued MiPSCs displayed normal mitochondrial respiration and energy production. Moreover, neuronal progenitor cells differentiated from the rescued MiPSCs also demonstrated normal metabolic profiles. Furthermore, we successfully achieved reduction in the human m.3243A>G mtDNA mutation in porcine oocytes via injection of mitoTALEN mRNA. Our study shows the great potential for using mitoTALENs for specific targeting of mutant mtDNA both in iPSCs and mammalian oocytes, which not only provides a new avenue for studying mitochondrial biology and disease but also suggests a potential therapeutic approach for the treatment of mitochondrial disease, as well as the prevention of germline transmission of mutant mtDNA.

OBJECTIVE:To construct integrated medication decision-making system,and to provide reference for safe,effec-tive,economical and reasonable drug use in clinic. METHODS:The construction of integrated medication decision-making system was introduced in our hospital. RESULTS&CONCLUSIONS:The integrated medication decision-making system included three as-pects as real-time intervention in advance,interactive review in the matter,afterward comment and analysis,as 3 steps before and after the implementation of inpatient medical order and outpatient prescription. The real-time intervention in advance was mainly to control the rationality of medical orders or prescriptions from their source,thus requiring the timely treatment. The interactive re-view in the matter required that pharmacists judged the medical order or prescription and made a decision of refusing prescribing within the fixed time. To make a decision accurately,the clinical information should be highly structured and correlated with drug signs. Afterward comment and analysis required that pharmacists evaluated the medical order or prescription regularly after the im-plementation. The three were not only different,but also coordinated,and they were an organic unity,especially interactive review in the matter needed to be coordinated with the other two processes. After the implementation of integrated medication decision-mak-ing system,the proportion of irrational medical orders or prescriptions in our hospital decreased from 6.07% in the first half of 2016 to 2.56% at corresponding period of 2017. Drug dose errors and incompatibility were greatly reduced,and medication against contraindications was more likely to be found in the review and analysis. The system can improve the efficiency of prescription re-view,improve rational drug use,and effectively ensure the safety,effectiveness,economy and rationality of clinical drug use.

OBJECTIVE:To provide reference and evidence for rational use of clinical nutrition. METHODS:The types of en-teral and parenteral nutrition and the cost of prescription were analyzed statistically in 17 third grade class A general hospitals,3 third grade class A special hospitals and 14 secondary general hospitals from Shanghai area during 2011 to 2013. RESULTS:Nutri-tion preparations were mainly used by hospitalized patients. Total cost of nutrition preparations in outpatient and emergency depart-ment respectively occupied 8.14%,8.77% and 8.89% of total cost of nutrition preparations in the hospital during 2011-2013. The parenteral nutrition was the main form of nutritional support. There were only three kinds of enteral nutrition in top ten nutrition preparations in the list of prescription cost. Although seven out of ten kinds of nutrition preparations were given enterally which was the main mode for outpatients and emergency patients,the cost of prescriptions of parenteral nutrition increased faster compared to enteral nutrition,especially alanyl-glutamine. CONCLUSIONS:Parenteral nutrition is the main mode of nutrition support,especial-ly for inpatients;great attention should be paid to the increase of the cost of prescriptions about parenteral nutrition in outpatients and emergency patients.
