OBJECTIVE: To explore the therapeutic effect of multiple small diameter drilling combined with extracorporeal shock wave therapy (ESWT) under C-arm X-raylocalization in patients with early osteonecrosis of the femoral head (ONFH). METHODS: A total of 106 cases of early ONFH patients admitted from May 2015 to May 2017 were retrospectively selected as the study subjects. According to different treatment methods, the patients were divided into observation group and control group, 53 cases in each group. The observation group was treated with multiple small-diameter drilling combined with ESWT under C-arm positioning in the observation group, including 41 males and 12 females with an age of (45.85±6.01) years old (22 to 70 years old);and the control group was treated with ESWT, including 34 males and 19 females with an age of (45.12±5.83) years old(20 to 68 years old) in the control group. The modified Harris hip scores(mHHS), visual analog scale(VAS), hip flexion range, hip abduction and adduction range, ONFH area ratio and clinical efficacy were compared between twe groups before and after treatment. Kaplan-Meier method was used to draw a survival curve to compare the femoral head survival rate between two groups during the 3-year follow-up period after treatment. RESULTS: There were no complications such as poor wound healing and infection. All of 106 patients were followed up for 28 to 36 months with an average of (31.06±4.28) months. MHHS score, hip flexion range and hip abduction and adduction range in the observation group were increased from (63.85±5.42) scores, (23.79±2.21) °, (32.40±4.19) ° before treatment to (85.51±5.69) scores, (34.65±2.73)°, (43.32±5.71)° at 2 years after treatment, respectively(P<0.05). The above indicators in the control group increased from (64.73±5.64)°, (23.82±2.18)°, (32.45±4.13)° before treatment to (81.65±5.48) scores, (32.79±2.87)°, (39.75±5.68)°at two years after treatment, respectively(P<0.05). VAS score and ONFH area ratio in the observation group decreased from (5.76±1.41) scores and (35.07±4.96)% before treatment to (3.39±1.02) scores and (22.04±3.23)% at 2 years after treatment, respectively(P<0.05). The above indicatiors in control group decreased from (5.73±1.45) scores and (35.24±5.18)% before treatment to (4.43±1.21) scores and (28.32±3.76)% at 2 years after treatment, respectively(P<0.05), and the improvement in the observation group was significantly higher than that in the control group(P<0.05). At 3 years after treatment, the femoral head survival rate in the observation group was higher than that in the control group (P<0.05). CONCLUSION Multiple small diameter drilling combined with ESWT under C-arm positioning can significantly improve the clinical symptoms of patients with early ONFH, relieve pain and improve clinical efficacy.

Aim To explore the mechanism of grape seed proanthocyanidins (GSPs) targeting astrocytes (AS), so as to regulate the phenotype and function of AS and maximize their neuroprotective effect. Methods The effects of GSPs on the phenotype, secretion of pro-inflammatory factors and neurotrophic factors of Al AS induced by TNF-α, IL-1α and Clq were investigated by RT-PCR, Elisa and Western blot in vitro. And JNK phosphorylation was determined using Western blot. Results GSPs significantly reduced the expression of C3d and Clq of Al AS markers and inhibited the phosphorylation of JNK. Moreover, compared with the model group, GSPs could significantly inhibit the release of pro-inflammatory cytokines IL-6, IL-1 α, IL-17 and H

Amyloid β-protein(Aβ) deposition in the brain is directly responsible for neuronal mitochondrial damage of Alzheimer's disease(AD) patients. Mitophagy, which removes damaged mitochondria, is a vital mode of neuron protection. Ginsenoside Rg_1(Rg_1), with neuroprotective effect, has displayed promising potential for AD treatment. However, the mechanism underlying the neuroprotective effect of Rg_1 has not been fully elucidated. The present study investigated the effects of ginsenoside Rg_(1 )on the autophagy of PC12 cells injured by Aβ_(25-35) to gain insight into the neuroprotective mechanism of Rg_1. The autophagy inducer rapamycin and the autophagy inhi-bitor chloroquine were used to verify the correlation between the neuroprotective effect of Rg_1 and autophagy. The results showed that Rg_1 enhanced the viability and increased the mitochondrial membrane potential of Aβ-injured PC12 cells, while these changes were blocked by chloroquine. Furthermore, Rg_(1 )treatment increased the LC3Ⅱ/Ⅰ protein ratio, promoted the depletion of p62 protein, up-regulated the protein levels of PINK1 and parkin, and reduced the amount of autophagy adaptor OPTN, which indicated the enhancement of autophagy. After the silencing of PINK1, a key regulatory site of mitophagy, Rg_1 could not increase the expression of PINK1 and parkin or the amount of NDP52, whereas it can still increase the LC3Ⅱ/Ⅰ protein ratio and promote the depletion of OPTN protein which indicated the enhancement of autophagy. Collectively, the results of this study imply that Rg_1 can promote autophagy of PC12 cells injured by Aβ, and may reduce Aβ-induced mitochondrial damage by promoting PINK1-dependent mitophagy, which may be one of the key mechanisms of its neuroprotective effect.

Purpose: This study aimed to compare the ability of B-mode ultrasonography and magnetic resonance imaging (MRI) to predict the repairability of large-to-massive rotator cuff tears (RCTs). Methods: This cross-sectional study included participants with large-to-massive RCTs who underwent arthroscopic repair. B-mode ultrasonography and MRI were conducted prior to arthroscopic repair. B-mode ultrasonography was used to evaluate the echogenicity of the rotator cuff muscle using the Heckmatt scale. Intra-rater and inter-rater reliabilities were examined for two independent physicians. MRI was used to evaluate the degrees of tendon retraction, fatty infiltration of rotator cuff muscles, and muscle atrophy. Finally, two experienced orthopedic surgeons performed surgery and decided whether the torn stump could be completely repaired intraoperatively. Results: Fifty participants were included, and 32 complete repairs and 18 partial repairs were performed. B-mode ultrasonography showed good intra-rater reliability and inter-rater reliability for assessment of the muscle echogenicity of the supraspinatus and infraspinatus muscles. The correlation coefficients between B-mode ultrasound findings and MRI findings showed medium to large effect sizes (r=0.4-0.8). The Goutallier classification of the infraspinatus muscles was the MRI predictor with the best discriminative power for surgical reparability (area under the curve [AUC], 0.89; 95% confidence interval [CI], 0.81 to 0.98), while the Heckmatt scale for infraspinatus muscles was the most accurate ultrasound predictor (AUC, 0.85; 95% CI, 0.74 to 0.96). No significant differences in AUCs among the MRI and ultrasound predictors were found. Conclusion B-mode ultrasonography was a reliable examination tool and had a similar ability to predict surgical reparability to that of MRI among patients with large-to-massive RCTs.

There is a rare case of an elderly diabetic with diabetic foot infection at Hainan General Hospital in September 2021, which was diagnosed as Corynebacterium diphtheriae infection incidentally on routine culture with conventional methods and molecular biological approaches, to aid in diagnosis in clinical practice. Owing to smear staining, Albert staining and VITEK 2 system, automated identification systems viz matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) confirmed combing with 16S ribosomal RNA (16S rRNA) gene has been used for the taxonomic classification of bacteria. Otherwise, toxin gene tox was done for diphtheria toxin synthesis. The isolate was Gram-stain-positive, rod-like arrangement with irregular thickness, with characteristic metachromatic granules, ferment most sugars and homology of 16S rRNA analyses with C. diphtheriae NCTC11397^T (MW682323.1) was greater than a 100% possibility, toxin gene tox was negative. The findings lay the foundation to clinical identify and trace of non-toxigenic C. diphtheriae. Moreover, this work provides insights into the non-toxigenic C.diphtheriae that contribute to recognized risk of non-toxigenic C.diphtheriae infections.

Asthma is one of the common chronic respiratory diseases, and its incidence has been increasing worldwide in recent years. In the context of climate change, the frequency and intensity of extreme weather events are increasing. A large body of evidence suggests that exposure to extreme temperatures can increase the risk of asthma attacks, but the underlying mechanisms that trigger asthma attacks are still unclear. This study aims to systematically review the research progress on the association between extreme temperature and asthma attacks, and to elucidate the synergistic effects of extreme temperatures, indoor/outdoor environments, and individual vulnerabilities on asthma attacks. Additionally, this review discusses the potential mechanisms of asthma attacks triggered by extreme temperature, and highlights the important role of immune regulation and neuroregulation in the inflammatory response of asthma induced by extreme temperature. Moreover, we propose a potential mechanism framework to explain the disease pathogenesis of asthma which is induced by the interactions between extreme temperature and environmental factors, in order to provide a scientific basis for addressing the adverse impacts of extreme weather events and climate change.

Objective:To explore the value of iterative decomposition of water and fat with asymmetry and least squares estimation-quantitative fat imaging (IDEAL-IQ) in quantitative evaluation of thigh muscle fat content and its correlation with muscle strength in middle-aged and elderly volunteers.Methods:From December 2020 to April 2021, 30 volunteers aged 45 to 70 were recruited prospectively, including 15 males and 15 females with 52.5 (49.0, 56.3) years old. All subjects were scanned at 3.0 T MR, including axial T 1WI, IDEAL-IQ and coronal T 2WI of the left thigh. The region of interest of the knee extensors (quadriceps femoris) and knee flexors (hamstrings) in the left mid-thigh were delineated, and muscle cross-sectional area (CSA), skeletal muscle index (SMI), intermuscular fat fraction (FF) and intramuscular FF were obtained. In addition, isokinetic muscle strength measurement was performed on the left knee joint of all subjects at angular speeds of 60°/s and 180°/s to obtain peak torque (PT) and total work (TW) of knee flexors and extensors. Independent sample t-test, paired t-test or Mann-Whitney U test were used to compare the differences of CSA, SMI, intermuscular FF, intramuscular FF, PT and TW between different genders and muscle groups. Pearson or Spearman correlation analysis, and multiple linear regression analysis were used to analyze the correlation between CSA, SMI, intermuscular FF, intramuscular FF and PT, TW of thigh muscles. Results:The CSA, PT and TW of thighs in males were higher than those in females ( P<0.05), while the intermuscular FF in males was lower than that in females ( P=0.005). The CSA, SMI and PT of the thigh extensors were higher than those of the flexors ( P<0.001), while the intramuscular FF and intermuscular FF were lower than those of the flexors ( P<0.001). Intramuscular FF of flexors and extensors were moderately negatively correlated with PT ( r=-0.635, P<0.001; r=-0.546, P<0.001), and highly, moderately negatively correlated with TW ( r=-0.718, P<0.001; r=-0.616, P<0.001). Intermuscular FF of flexors and extensors were moderately negatively correlated with PT ( r=-0.519, P=0.003; r=-0.443, P=0.014), and negatively correlated with TW ( r=-0.363, P=0.049; r=-0.552, P=0.002). There was no significant correlation between CSA, SMI and PT, TW in flexors and extensors of thigh ( P>0.05). Multiple linear regression analysis showed that intramuscular FF was still significantly correlated with PT and TW of flexors and extensors (flexors: R 2adj=0.505, P=0.001; R 2adj=0.540, P<0.001; extensors: R 2adj=0.351, P=0.006; R 2adj=0.470, P=0.002). Conclusion:FF based on IDEAL-IQ technology can accurately quantify the intramuscular and intermuscular fat content of thighs, and there are negative correlations between intramuscular FF, intermuscular FF and isokinetic muscle strength measurements including PT and TW. Among them, intramuscular FF is more significant.
