ABSTRACT
OBJECTIVE:With the popularity of simulated barefoot running,minimalist shoes have become a new way of foot exercise.As an important muscle group of the foot,the maintenance of foot muscle morphology is important for the execution of foot functions.In this paper,by combing the literature about the effect of minimalist shoes on foot muscle morphology in recent years,we systematically evaluate the effect of minimalist shoes on foot muscle morphology compared with traditional running shoes. METHODS:The relevant articles published from 2012 to 2022 were searched in Chinese and English databases(PubMed,Web of Science,ProQuest,CNKI and WanFang databases)with"minimal shoes,minimal footwear,minimalist shoes,minimalist footwear,foot muscle,feet muscle"as Chinese and English keywords,respectively.Meta-analysis,sensitivity tests were performed on the included literature using Review Manager 5.4.1 and Stata 14 software,the Egger method was used to test for publication bias in the literature,and Meta-regression was used to identify the subgroups with heterogeneity. RESULTS:Compared with traditional running shoes,minimalist shoes increased muscle circumference of the abductor hallucis[standardized mean difference=2.034,95%confidence interval(1.192,2.877),Z=4.73,P＜0.001].And the results were not reversed after clipping and patching,with a more robust combined effect size(P＜0.05).For the toe short flexors,the total combined effect size did not show a difference between traditional running shoes and minimalist shoes[standardized mean difference=0.470,95%confidence interval(-0.45,1.39),Z=1.00,P=0.318]. CONCLUSION:Compared with traditional running shoes,minimalist shoes intervention can effectively improve muscle circumference of the abductor hallucis,but the promoting effect on the flexor digitorum brevis muscle is not obvious.Running in minimalist shoes has positive implications for the maintenance of the medial longitudinal arch,but it is necessary to enrich the research content of minimalist shoes on different foot muscles and different populations in order to further explore the mechanisms by which minimalist shoe interventions promote foot function.
ABSTRACT
Objective:To analyze the clinical characteristics and risk factors of impaired liver and renal function in hospitalized patients with gout.Methods:A total of 494 hospitalized patients with confirmed gout were selected and divided into four groups according to liver and renal function, control(Con), impaired liver function (ILF), impaired renal function (IRF), and both function impaired (ILRF) group. Multivariate logistic regression was used to analyze the risk factors related with impaired liver and renal function.Results:Compared to Con group, ILF group were younger with shorter gout duration, higher body mass index, waist circumference, homeostasis model assessment for insulin resistance (HOMA-IR), serum uric acid, low density lipoprotein-cholesterol (LDL-C), total cholesterol, triglycerides, C reactive protein, higher prevalence of dyslipidemia, obesity, fatty liver, and monosodium urate crystal (MSU) deposition (all P<0.05). IRF group were older and with higher serum uric acid, serum creatinine, C reactive protein, and hypertension, MSU deposition prevalence, with lower prevalence of fatty liver (all P<0.05). Compared to ILF group, IRF group were older, with longer gout duration, lower level of body mass index, waist circumference, HOMA-IR, LDL-C, total cholesterol, triglycerides, lower prevalence of obesity, fatty liver, and higher prevalence of hypertension and type 2 diabetes (all P<0.05). The univariate logistic regression analysis showed that age( OR=0.941, 95% CI 0.906-0.977, P<0.001), serum uric acid ( OR=1.002, 95% CI 1.000-1.005, P=0.043), HOMA-IR ( OR=1.147, 95% CI 1.024-1.285, P=0.018), and MSU deposition ( OR=1.959, 95% CI 1.154-3.326, P=0.013) were the independent risk factors of impaired liver function, while the independent risk factors of impaired renal function were age ( OR=1.104, 95% CI 1.048-1.162, P<0.001), serum uric acid ( OR=1.007, 95% CI 1.004-1.010, P<0.001), and MSU deposition ( OR=2.393, 95% CI 1.191-4.805, P=0.014). Conclusions:Serum uric acid and MSU deposition are the common independent risk factors for impaired liver and renal function in patients with gout. Younger patients with insulin resistance are susceptible to impaired liver function, older patients with hypertension and diabetes are susceptible to impaired renal function.
ABSTRACT
To assess the clinical application of video head impulse test (vHIT) for vestibular function in vestibular neuritis (VN) and benign paroxysmal positional vertigo (BPPV) patients.Thirty-three patients with VN and 43 patients with BPPV were enrolled from Sir Run Run Shaw Hospital and Ningbo Second Hospital from March 15 to September 10, 2015; and 50 healthy controls were also enrolled in the study. vHIT was used to quantitatively test the vestibulo-ocular reflex (VOR) gains of a pair of horizontal semicircular canals. VOR gains two pairs of vertical semicircular canals, and the corresponding asymmetrical value of three VOR gains. The saccades information was also recorded.Compared with the healthy control group and BPPV patients, the affected horizontal and vertical VOR gains were declined and the corresponding asymmetries were increased in VN patients (all<0.01). BPPV group also showed higher vertical VOR gain asymmetries compared with the healthy control group (all<0.01), but no significant difference was observed in VOR gains and horizontal VOR gain asymmetry (all>0.05). The sensibility of vHIT in diagnosis of VN was 87.9%. Among 33 VN patients, 22 were diagnosed with superior vestibular nerve dysfunction, 7 were found with inferior vestibular nerve dysfunction and 3 were with both dysfunction; and 1 case was not distinguished.Video head impulse test can quantitatively evaluate the vestibular dysfunction of VN and can help early diagnosis of VN, which may be widely used in clinic.

OBJECTIVE:To observe the efficacy and safety of mirtazapine in the treatment of perimenopausal syndrome with sleep disorders. METHODS:100 perimenopausal patients with sleep disorders were randomly divided into study group(52 cases) and control group(48 cases). Study group was given Mirtazapine tablet with initial dose of 15 mg,once a day,taking 1-2 hours before going to bed,increased and maintained to 30 mg after 1 week. The control group was given Oryzanol tablet 10 mg after meals,3 times a day. Both groups were treated for 8 weeks. Scores of HAMD-17 and PSQI before and after treatment were ob-served,efficacy of depression and sleep were evaluated and and incidence of adverse reactions in 2 groups was observed. RE-SULTS:After treatment,HAMD-17 scores and PSQI scores in 2 groups were significantly lower than before,and study group was lower than control group,8 weeks0.05). CONCLUSIONS:Mirtazapine can improve the sleep disorders of peri-menopausal syndrome with rapid onset,but the adverse reactions need futher observation.
