Objective To investigate the relationship between interleukin-1β (IL-1β) and miR-185-5p in the process of joint injury in acute gouty arthritis (AGA). Methods The serum miR-185-5p levels of 89 AGA patients and 91 healthy volunteers were detected by real-time quantitative PCR. The correlation between miR-185-5p expression level and VAS score or IL-1β expression level was evaluated by Pearson correlation coefficient method. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of miR-185-5p in AGA. THP-1 cells were induced by sodium urate (MSU) to construct an in vitro acute gouty inflammatory cell model. After the expression level of miR-185-5p in THP-1 cells was upregulated or downregulated by transfection of miR-185-5p mimics or inhibitors in vitro, inflammatory cytokines of THP-1 cells, such as IL-1β, IL-8 and tumor necrosis factor α (TNF-α), were detected by ELISA. The luciferase reporter gene assay was used to determine the interaction between miR-185-5p and the 3'-UTR of IL-1β. Results Compared with the healthy control group, the expression level of serum miR-185-5p in AGA patients was significantly reduced. The level of serum miR-185-5p was negatively correlated with VAS score and IL-1β expression level. The area under the curve (AUC) was 0.905, the sensitivity was 80.17% and the specificity was 83.52%. Down-regulation of miR-185-5p significantly promoted the expression of IL-1β, IL-8 and tumor necrosis factor (TNF-α), while overexpression of miR-185-5p showed the opposite results. Luciferase reporter gene assay showed that IL-1β was the target gene of miR-185-5p, and miR-185-5p negatively regulated the expression of IL-1β. Conclusion miR-185-5p alleviates the inflammatory response in AGA by inhibiting IL-1β.

Objective:To evaluate percutaneous mechanical thrombectomy (PMT) using Aspirex device for treating acute iliofemoral deep vein thrombosis (IFDVT).Methods:The clinical and follow-up data of 68 patients with IFDVT at our institution from Jan 2019 to Jun 2021 was retrospectively analyzed.Results:Twenty-six patients who had received PMT combined with auxiliary catheter directed thrombolysis (CDT) were included into group A, and 42 patients received CDT alone were into group B.The final thrombus clearance rates were more than 50%, and the clinical efficacy of thrombolysis was achieved. Group A associated a significant reduction in lysis duration and UK dosage and hospital days and degree of detumescence after 24 h compared with group B,and all aforementioned differences were statistically significant. Hospitalization costs in group A were more than group B. At one year follow-up, there were no significant differences between the two groups in the cumulative prevalence post-thrombotic syndrome (PTS) and the Villalta score and primary patency (92.0% vs. 90.0% , χ2=0.059, P=0.807). Conclusions:The application of PMT using the Aspirex device for acute IFDVT was safe and effective, which could accelerate the clearance of thrombus, and reduce UK dosage, lysis duration, hospital days. However, it increased the hospitalization costs.

Recessive dystrophic epidermolysis bullosa (RDEB) is caused by loss-of-function mutations in the COL7A1 gene encoding the α-1 chain of type Ⅶ collagen, leading to reduced or absent expression of basement membrane type Ⅶ collagen (C7) . Currently, there is no effective treatment for this rare disease, and the management is mainly palliative and supportive. Gene therapy is expected to be an effective treatment of RDEB. This review summarizes current strategies of gene therapy in clinical trials for RDEB, as well as their progress, pros and cons, and prospects.

Objective    To evaluate the clinical effects of segmentectomy versus lobectomy under single utility port video-assisted thoracic surgery on inflammatory factors and immune cells in peripheral blood of non-small cell lung cancer patients, and to analyze the effect of changes of postoperative inflammatory factors and immune cells on the prognosis of the patients. Methods    The clinical data of 256 patients who underwent segmentectomy or lobectomy under single utility port video-assisted thoracic surgery for non-small cell lung cancer in the First Affiliated Hospital of Hebei North University from January 2016 to October 2020 were retrospectively collected. According to the operation method, they were divided into a segmentectomy group (126 patients with 79 males and 47 females at an age of 63.4±6.2 years) and a lobectomy group (130 patients with 91 males and 39 females at an age of 62.9±5.6 years). The change of inflammatory factors (C reactive protein, interleukin-6, interleukin-8, tumor necrosis factor-α) and immune cells (CD4+T cells, CD8+T cells and natural killer cells) were recorded and analyzed before operation (T0) and 1 day (T1), 3 days (T2), 7 days (T3), 1 month (T4) after the operation between the two groups. According to postoperative recurrence situations, they were divided into a recurrence group and a non-recurrence group, multivariate logistic regression analysis was used to analyze the relationship between the change of postoperative inflammatory factors, immune cells, and the prognosis of patients with non-small cell lung cancer. Results    (1) There was no statistical difference in sex ratio, underlying diseases, body mass index, levels of preoperative inflammatory factors or immune cells between the two groups (all P>0.05). (2) The changes of postoperative inflammatory factors in the segmentectomy group were significantly less than those in the lobectomy group at T1-T3 (all P<0.05), and the changes of postoperative immune cells in the segmentectomy group were significantly less than those in the lobectomy group at T1-T4 (all P<0.05). (3) The changes of postoperative inflammatory factors and immune cells on postoperative day 3 in the recurrence group were significantly more than those in the non-recurrence group (all P<0.05). (4) Multivariate logistic regression analysis showed that the changes of postoperative inflammatory factors and immune cells on postoperative day 3 may be the risk factors for postoperative recurrence and metastasis in patients with non-small cell lung cancer (all P<0.05). Conclusion    Single utility port video-assisted thoracic surgery segmentectomy for the treatment of non-small cell lung cancer can reduce the inflammatory response and protect body's immune function, and the change of postoperative inflammatory factors and immune cells in postoperative day 3 may be the risk factors for postoperative recurrence and metastasis in patients with non-small cell lung cancer.

Drug-drug interactions (DDI) of tyrosine kinase inhibitors (TKIs) mediated by metabolic enzymes and transporters have become an important issue in clinical practice recently. In addition to CYP450 enzymes, uridine diphosphate glucuronidases (UGTs) are another class of metabolic enzymes involved in the metabolism of TKIs, and most TKIs can inhibit the UGTs in vitro. Potential clinically meaningful DDIs may occur with the co-administration of TKIs and substrates or inhibitors of UGTs. This paper will mainly focus on the UGTs-mediated drug-drug and the effect of UGT1A genotype on the drug interactions of TKIs and explores strategies to address, aiming to provide clinicians and pharmacists with references for the safe and rational application of TKIs.

Objective To study the effects of excitation source, intraocular pressure and material parameters on frequency response of human eye under acoustic excitation. Methods Based on the three-dimensional (3D) finite element model of the whole eye, as well as the deformation and stress distribution of human eye, the effects of various parameters on frequency response of human eye were quantitatively analyzed. Results When other parameters were fixed and only the position and size of the excitation source changed, the amplitude at resonance of human eye (the acoustic excitation source was placed directly above the cornea, at an offset of 45°, and at larger excitation) at 134 Hz was 35, 48 and 133 μm, respectively. When only the intraocular pressure changed, the first-order resonance frequency was almost unaffected by the intraocular pressure, and the resonance frequencies of other orders would shift slightly to the left as the intraocular pressure increased. When only the scleral elastic parameters changed, the resonance frequency of eye tissues increased with the increase of the scleral elasticity. Conclusions The position and size of the excitation source have no effects on resonance frequency of human eye, but they have a greater effect on the resonance amplitude. The material parameters of human eye tissues have a greater effect on the frequency response, and there is a linear relationship between the intraocular pressure and resonance frequency. The results provide the theoretical basis for clinical development of high-performance intraocular pressure monitoring technology.

Sudden sensorineural hearing loss (SSNHL) refers to the sudden and unexplained sensorineural hearing loss within 72 h and a decrease in hearing of ≥30 dB affecting at least 3 consecutive frequencies. It is one of the common emergencies in neurology and otolaryngology. Early etiological evaluation and systematic and targeted treatment are very important for delaying the progression of SSNHL and restoring hearing. Recent studies have shown that SSNHL overlaps with vascular risk factors of ischemic stroke, and may predict the risk of ischemic stroke. SSNHL may be one of the clinical manifestation and even the prodromal symptoms of ischemic stroke, especially the infarction of the blood supply area of the anterior inferior cerebellar artery or its branch internal auditory artery. Although these factors can not fully reveal the relationship between SSNHL and ischemic stroke, they are enough to warn clinicians that they should consider the possibility of ischemic stroke when receiving patients with SSNHL. Screening of vascular risk factors for patients with SSNHL as early as possible is helpful to avoid the risk of recurrence of ischemic stroke.

Objective:To explore the advantages of the novel individualized 3D printing artificial vertebral body in spine reconstruction and to evaluate its clinical effect.Methods:From January 2017 to December 2018, the 15 patients who underwent total vertebrectomy and spine reconstruction with individualized 3D printing artificial vertebral body were analyzed retrospectively. There were 8 males and 7 females, with the mean age 39.5 years (range: 20-57), including 12 primary tumors and 3 metastatic tumors. According to tumor location and surrounding soft tissue invasion range, simple posterior or combined anterior and posterior approach were used for total vertebral resection, and the defection was reconstructed by 3D printing artificial vertebral body. The operation time, intraoperative bleeding volume, postoperative stability of artificial vertebral body and bone ingrowth of adjacent vertebral body, preoperative and postoperative neurological changes, preoperative and postoperative VAS score, local control and survival of patients were analyzed.Results:The mean operation time was 412.0 min (range: 135-740 min), and the mean blood loss was 4 140.0ml (range: 100-14 000 ml). The mean follow-up time was 23.2 months (range: 12-35 months), and no one loss to follow-up. One case had pleural rupture, one case had cerebrospinal fluid leakage and one case had L5 nerve root palsy. All patients recovered after active symptomatic treatment. Compare with the preoperative VAS score (4.7±1.1), the differences of VAS score at 7 d postoperative and last follow-up (1.6±0.6 and 1.0±0.5) were significantly reduced ( P<0.001). Three patients with Frankel grade C gradually recovered to grade D, and no change were found in grade D and Grade E patients, there was no significant improved at last follow-up. Preliminary bone growth was found between the artificial vertebral body and the adjacent vertebral body 3 months after operation. The bone growth was more obvious at 12 months post-operation, and the artificial vertebral body fused with the adjacent vertebral bodies to form bone integration. At 24 months post-operation, the integration of the artificial vertebral body was more accurate. During the follow-up period, there was no loosening or displacement of the artificial vertebral body and no failure of internal fixation. A case of hemangioendothelioma and a case of epithelioid angiosarcoma died at 33 months and 35 months postoperatively. One patient with chondrosarcoma had local recurrence at16 months post-operation. After treated with arotinib, the tumor did not progress. The other 12 patients had no tumor recurrence or distant metastasis. Conclusion:After spinal tumor resection, individualized 3D printing artificial vertebral body can be used to accurate restoration of spinal continuity, and provide nice interface matching and bone growth between artificial vertebral body and the adjacent vertebral endplates. Moreover, the immediate and long-term stability of the artificial vertebral body can meet the needs of spinal reconstruction.
