Objective To investigate the expression levels of peroxisome proliferator-activated receptor gamma coactivator-1β(PGC-1β),hypoxia-inducible factor-1α(HIF-1α),and resistin(RETN)in gouty arthri-tis(GA),and analyze their correlation with the degree of joint damage.Methods A total of 134 patients with GA in the hospital from January 2022 to October 2023 were selected as GA group,and 134 healthy people who underwent the physical examination in the same period were selected as control group.The serum expression levels of PGC-1β,HIF-1α and Retn were compared between the two groups.The expression levels of PGC-1β,HIF-1α and Retn in serum and synovial fluid of patients with different clinical characteristics in GA group were compared,the degree of joint destruction was graded according to the subjective pain grading method(VAS)and the patients were divided into a severe GA subgroup of 78 cases and a mild GA subgroup of 56 ca-ses.The expression levels of PGC-1β,HIF-1α,RETN,bone destruction factors[β-cross linked degradation products(β-CTX),tartrate resistant acid phosphatase-5b(TRACP5b),receptor activator of nuclear factor kappa B ligand(RANKL)]and inflammatory factors[tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β)]were compared among different degrees of joint destruction,and the correlation between serum and syno-vial fluid PGC-1β,HIF-1α,RETN and the degree of joint destruction,bone destruction factors,and inflamma-tory factors was analyzed.Results The expression level of PGC-1β in serum of GA group was lower than that of the control group,while the expression levels of HIF-1α and RETN in serum were higher than those of the control group(P＜0.05).There were statistically significant differences in serum and synovial fluid PGC-1β,HIF-1α,and RETN levels among GA patients with different clinical stages,affected joints,disease duration,and annual seizure frequency(P＜0.05).The expression levels of PGC-1β in the serum and synovial fluid of the severe GA subgroup were lower than those of the mild GA subgroup(P＜0.05),while the expression lev-els of HIF-1α and RETN were higher than those of the mild GA subgroup(P＜0.05).The expression levels ofβ-CTX and TRACP5b in the severe GA subgroup were higher than those in the mild GA subgroup(P＜0.05),while the expression level of RANKL was lower than that in the mild GA subgroup(P＜0.05).PGC-1βin serum and synovial fluid was negatively correlated with the degree of joint destruction,β-CTX,TRACP5b,TNF-α,and IL-1β,and positively correlated with RANKL.HIF-1α and RETN were positively correlated with the degree of joint destruction,β-CTX,TRACP5b,TNF-α,and IL-1β,and negatively correlated with RANKL.Conclusion PGC-1β,HIF-1α,and RETN are abnormally expressed in patients with GA,and are closely associ-ated with the degree of joint destruction,bone destruction factors,and inflammatory factors.They are expec-ted to become reliable indicators for evaluating the occurrence and progression of GA.

Objective:To explore the effects of visual feedback training based on the mirror neuron theory in upper limb function reconstruction in stroke patients.Methods:From June 2017 to June 2018, totally 61 stroke patients hospitalized in the Rehabilitation Medical Center of the Second Hospital of Jiaxing were selected by convenient sampling and divided into the observation group ( n=31) and the control group ( n=30) according to the random number table. Patients in both groups received routine rehabilitation therapy, while patients in the observation group underwent visual feedback training on this basis. They were evaluated using Barthel Index , Fugl-Meyer Assessment (FMA) (upper limb) , and the latency and amplitude of N9 and N20 were detected using somatosensory evoked potentials (SEP) before and 8 weeks after rehabilitation intervention. Results:After the intervention, the FMA score of the upper limbs in the observation group was (47.91±6.92) , higher than (40.31±7.87) in the control group, the Barthel Index of the observation group was (77.33±11.82) , higher than (66.79±12.31) in the control group, and the differences between the two groups were statistically significant ( P<0.01) . The SEP values of the upper limbs of the hemiplegia side in the observation group were better than those in the control group, and the differences between the two groups were statistically significant ( P<0.05) . Conclusions:The visual feedback training based on the mirror neuron theory can improve the upper limb motor function in stroke patients with early hemiplegia, improve their daily living activities, increase the N9 and N20 amplitudes of SEP, shorten their latency, and enhance the excitement of the upper limb movement related brain area in the mirror neuron system.

Objective To explore the impacts of leukoaraiosls (LA) on the short-term outcome of acute cerebral infarction. Methods 204 patients after acute cerebral infarction were reviewed from January 2012 to August 2014. They were divided into 4 groups according to the brain magnetic resonance imaging: cerebral infarction without LA (LA-0), and with LA (LA-1, LA-2 and LA-3). The Logistic regression analysis was applied with the short-term outcome of cerebral infarction as the dependent variable, and 16 possible factor as independent variables. Results There were 4 independent factors risk to the worse outcome of acute cerebral infarction, including LA, age, hypertension and cerebral infarction size (OR>1, P<0.05). Conclusion LA is an independent risk factors to the worse short-term outcome of acute cerebral infarction.

[Objective] To explore the anti-inflammatory effects of emodin and its therapeutic effect on acute lung injury. [Methods] By means of analyzing the relevant literatures in PUBMED,CNKI,CBM,Wanfang and Vip Da-tabase from 1998 to 2012,summarized the anti-inflammatory effects and mecha-nisms of emodin, as wel as its therapeutic effect on acute lung injury. [Results] A variety of studies have confirmed the anti-inflammatory effects of emodin, whose mechanism is related to emodin inhibiting the activation of NF-kappa B,modulaing various inflammatory factors, etc. In addition, the effect of emodin in the treatment of acute lung injury has been confirmed on celland animal levels. [Conclusion] Emodin has good prospect of clinical application.

OBJECTIVETo identify endophytic fungi bn12 from Cinnamomum camphora chvar, borneol and analysis its volatile metabolites.

METHODThe endophytic fungi bn12 was identified by morphological observation. volatile metabolites of endophytic fungi bn12 was analyzed by gas chromatography/mass spectrography (GC-MS).

RESULTVolatile metabolites of endophytic fungi bn12 contain borneol and much indoles. The ITS sequence of endophytic fungi bnl2 is most similar to the ITS sequence of pleosporaceae fungus, particularly C. nisikadoi.

CONCLUSIONEndophytic fungi bn12 is belong to pleosporaceae fungus. It has the ability of producing broneol.
