ABSTRACT

Background and Objectives@#This study aims to clarify the systems underlying regulation and regulatory roles of hydrogen combined with 5-Aza in the myogenic differentiation of adipose mesenchymal stem cells (ADSCs). @*Methods@#and Results: In this study, ADSCs acted as an in vitro myogenic differentiating mode. First, the Alamar blue Staining and mitochondrial tracer technique were used to verify whether hydrogen combined with 5-Aza could promote cell proliferation. In addition, this study assessed myogenic differentiating markers (e.g., Myogenin, Mhc and Myod protein expressions) based on the Western blotting assay, analysis on cellular morphological characteristics (e.g., Myotube number, length, diameter and maturation index), RT-PCR (Myod, Myogenin and Mhc mRNA expression) and Immunofluorescence analysis (Desmin, Myosin and β-actin protein expression). Finally, to verify the mechanism of myogenic differentiation of hydrogen-bound 5-Aza, we performed bioinformatics analysis and Western blot to detect the expression of p-P38 protein. Hydrogen combined with 5-Aza significantly enhanced the proliferation and myogenic differentiation of ADSCs in vitro by increasing the number of single-cell mitochondria and upregulating the expression of myogenic biomarkers such as Myod, Mhc and myotube formation. The expressions of p-P38 was up-regulated by hydrogen combined with 5-Aza. The differentiating ability was suppressed when the cells were cultivated in combination with SB203580 (p38 MAPK signal pathway inhibitor). @*Conclusions@#Hydrogen alleviates the cytotoxicity of 5-Aza and synergistically promotes the myogenic differentiation capacity of adipose stem cells via the p38 MAPK pathway. Thus, the mentioned results present insights into myogenic differentiation and are likely to generate one potential alternative strategy for skeletal muscle related diseases.

ABSTRACT

Objective To analyze the equity and efficiency of resource allocation for management and treatment of severe mental disorders in Shanghai in 2020, and to provide a foundation for making relevant policies. Methods Data on resource allocation for the management and treatment of severe mental disorders in 17 district-level mental health institutions in 2020 were collected. The Gini coefficient was used to evaluate the equity of resource allocation by population and geographic area, and data envelopment analysis was carried out to analyze the equity of resource allocation. Results The Gini coefficients of special funds, psychiatric medical staff and actual open beds according to population were 0.24, 0.25 and 0.27, respectively. The Gini coefficients according to area were 0.54, 0.62 and 0.64, respectively. The average efficiency of resource allocation was 0.865. There were 5 institutions where DEA was effective, accounting for 29.41%. There were 12 institutions where DEA was non-effective, accounting for 70.59%. Conclusion The equity of resources allocation for the management and treatment of severe mental disorders according to population is good, but the equity of allocation based on geographic area is not high. The efficiency of resource allocation needs to be further improved. It is suggested that the resource allocation should be optimized to promote the fairness and efficiency of resource allocation for the management and treatment of severe mental disorders.

ABSTRACT

ObjectiveTo evaluate the clinical efficacy of TDP (specific electromagnetic wave) combined with Osteoking in the treatment of knee osteoarthritis of Qi stagnation and blood stasis type. MethodA total of 104 patients with knee osteoarthritis of Qi stagnation and blood stasis type, who received conservative therapy in The Third People's Hospital of Xinjiang Uygur Autonomous Region from July 2019 to December 2021, were randomized into the control group and study group with the random number table method, 52 cases in either group. The control group was treated with TDP, and the study group with TDP and Osteoking. The treatment lasted 1 week for both groups, with 1-month follow-up. Subjective indexes of visual analog scale (VAS) score and Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) score, and objective indexes of visual tenderness index and visual knee range of motion were determined before and after treatment to evaluate the pain and functions of patients. Traditional Chinese medicine (TCM) syndrome score was calculated. The serum erythrocyte sedimentation rate (ESR) and high sensitivity C-reactive protein (hs-CRP) were detected before and after treatment, and the total clinical effective rate was calculated. ResultBefore treatment, the baseline information and all the scores of the two groups were comparable. After treatment, the VAS score, WOMAC score, tenderness index, knee range of motion, and TCM syndrome score were improved in both groups (P<0.01). After the treatment, the VAS score and WOMAC score of the study group were lower than those of the control group (P<0.01) and the improvement of tenderness index in the study group was better than that in the control group (P<0.05). The knee range of motion in the study group was better than that in the control group (P=0.061). The TCM syndrome score of study group was lower than that of control group (P<0.01) after treatment. The post-treatment serum ESR and hs-CRP level in the two groups decreased significantly after treatment, and the study group were lower than those of the control group (P<0.01). The total clinical effective rate of the study group was 90.4%(47/52), as compared with the 53.8%(28/52) in the control group (P<0.05). No obvious adverse events occurred during treatment in both groups. ConclusionThe clinical efficacy of TDP combined with Osteoking in the treatment of knee osteoarthritis of Qi stagnation and blood stasis type is remarkable, which can improve knee pain and functions, alleviate TCM syndrome, and reduce inflammatory indexes, with high safety.

ABSTRACT

ObjectiveTo observe the effects of Qingzao Jiufeitang on the expression of adenosine 5′-monophosphate (AMP)-activated protein kinase (AMPK), mammalian target of rapamycin (mTOR), and UNC-51-like kinase 1 (ULK1) in lung cancer cells after the application of AMPK inhibitor (compound C). MethodMale C57BL/6J mice were randomly divided into a model group, a cyclophosphamide (CTX) group (50 mg·kg-1), a Qingzao Jiufeitang group (11 g·kg-1), an AMPK inhibitor group (10 mg·kg-1), and a Qingzao Jiufeitang combined with AMPK inhibitor group (combination group) (11 g·kg-1+10 mg·kg-1). Lewis lung cancer cells were subcutaneously injected into the right axilla to induce a tumor-bearing model. 24 hours after modeling, the mice in the CTX group were intraperitoneally injected once every other day for seven times in total. The mice in the AMPK inhibitor group and the combination group received intraperitoneal injection of compound C, once a day for 14 days. The mice in the Qingzao Jiufeitang group and the combination group were administered orally at the set dose for 14 days before and after modeling. At the end of the experiment, the mice in each group were sacrificed. The tumor-bearing tissues were collected, and the tumor weight of each group was counted. Transmission electron microscopy (TEM) was used to observe the formation of autolysosomes in lung cancer tissues of each group. Western blot was used to detect the protein expression of AMPK, phosphorylated AMPK (p-AMPK), mTOR, phosphorylated mTOR (p-mTOR), ULK1, phosphorylated ULK1 (p-ULK1), microtubule-associated protein 1 light chain 3B (LC3B), and p62. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of lung cancer in each group. ResultCompared with the model group, the Qingzao Jiufeitang group showed decreased tumor weight (P<0.01), the formation of autolysosomes under the electron microscope, increased protein expression of p-AMPK, p-ULK1, LC3B, LC3B-Ⅱ, and p-AMPK/AMPK, p-ULK1/ULK1, and LC3B-Ⅱ/LC3B-Ⅰratios (P<0.01, P<0.05), and reduced protein expression of p-mTOR, p62, and p-mTOR/mTOR ratio (P<0.05). Compared with the Qingzao Jiufeitang group, the combination group showed no autolysosomes formation under the electron microscope, decreased protein expression of p-AMPK, p-ULK1, LC3B, LC3B-Ⅱ, and p-AMPK/AMPK, p-ULK1/ULK1, LC3B-Ⅱ/LC3B-Ⅰ ratios (P<0.05, P<0.01), and increased p62 protein expression (P<0.05). HE staining results showed that the pathological changes of lung cancer tissues in the groups with drug intervention were improved compared with those in the model group. ConclusionQingzao Jiufeitang can promote the elevation of LC3B-Ⅱ and decrease the expression of p62 protein, thus inducing autophagy. The mechanism of autophagy initiation may be achieved by the AMPK/ULK1 pathway instead of the mediation by the AMPK/mTOR/ULK1 pathway.

ABSTRACT

ObjectiveTo explore the mechanism of Fangji Fulingtang in the treatment of acute kidney injury (AKI) induced by ischemia-reperfusion based on network pharmacology and experimental verification. MethodActive components of Fangji Fulingtang were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and previous report and targets of these components were predicted by SwissTargetPrediction. The targets of AKI were searched from GeneCards, Online Mendelian Inheritance in Man (OMIM), the database of gene-disease associations (DisGeNET), and Therapeutic Target Database (TTD). Protein-protein interaction (PPI) network was constructed by STRING. Metascape was used for Gene Ontology (GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment of core targets. Cytoscape was employed to construct the "medicinal-active component-target-disease" network and “active component-target-pathway” network. AutoDock was applied for molecular docking. Finally, animal experiment was carried out to validate the mechanism of Fangji Fulingtang in treatment of AKI. ResultA total of 137 active components and 858 targets of Fangji Fulingtang, 1 294 targets of AKI, and 267 targets of Fangji Fulingtang in the treatment of AKI were screened out. Phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1), phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA), proto-oncogene tyrosine protein kinase (SRC), protein kinase B1 (Akt1), and mitogen-activated protein kinase 3 (MAPK3) were the key anti-AKI targets of Fangji Fulingtang, which were involved in 1 609 GO terms, particularly cell response to lipids, membrane rafts, and protein kinase activity, and 140 KEGG pathways such as PI3K/Akt signaling pathway, chemokine signaling pathway, and Toll-like receptor signaling pathway. Molecular docking showed that the core active components had strong binding affinity to the key targets. The hematoxylin and eosin (HE) staining results indicated that Fangji Fulingtang can significantly improve the pathological state and the serological results suggested that the levels of serum creatinine (SCr) and blood urea nitrogen (BUN) were significantly reduced. ConclusionThis study clarified the mechanism of Fangji Fulingtang in the treatment of AKI and found that Fangji Fulingtang had the multi-component, multi-target, and multi-pathway characteristics in the treatment of AKI. The result lays a foundation for further study of its specific mechanism.

ABSTRACT

Objective:To explore the effect of potentially inappropriate medication (PIM) on frailty among community-dwelling elderly patients with mild cognitive impairment (MCI).Methods:From March to July 2021, a total of 252 elderly patients with MCI in Hefei community were selected.The data of basic information and PIM of subjects were collected.All subjects were assessed by the comprehensive frailty assessment instrument (CFAI), Montreal cognitive assessment scale-basic (MoCA-B), and the Barthel index (BI). The subjects were divided into PIM group ( n=136) and non-PIM group ( n=94) according to whether there was PIM.Taking the confounding factors as the matching condition, the subjects of the two groups were matched with 1∶1 propensity score.After matching, there were 52 in the PIM group and 52 in the non-PIM group.SPSS 23.0 was used for data analysis.Multivariate Logistic regression analysis was performed to analyze the effect of PIM on frailty of subjects. Results:(1)Before matching, the incidence of frailty in PIM group and non-PIM group were 80.9% and 19.1%, respectively, with statistically significant differences ( P<0.01). Logistic regression analysis revealed that PIM was a risk factor for the frailty ( β=1.704, OR=5.495, 95% CI=2.539-11.892). (2)After matching, the confounders of age, hearing status, chewing function, activities of daily living, Charlson comorbidity index, handgrip strength, and cognitive function were balanced and comparable between the two groups.The incidence of frailty in PIM group and non-PIM group were 67.9% and 32.1%, respectively.The differences remained statistically significant ( P<0.01). PIM remained a risk factor for frailty ( β=1.791, OR=5.998, 95% CI=2.393-15.032). Conclusion:PIM is a risk factor for the occurrence of frailty in elderly patients with MCI.Therefore, the accurate screening and standardized management of PIM will provide a new target for the frailty management of elderly patients with MCI.

ABSTRACT

As a new form of medical industry, internet medicine has not only the endogenous risk of internet industry, but also the blind area and exogenous risk because of lagging regulation. With the continuous progress of internet information technology, online diagnosis and treatment will gradually integrate and reconstruct the traditional medical service. In the history of medical development, the emergence of new technologies generally has the characteristics of risk. Therefore, the supervision of internet medicine should adhere to the rule of inclusiveness and prudence, and take into account the cultivation of the market and standardized development. It should also build a regulatory community, coordinate governance from the four dimensions of legitimacy, compliance, rationality and superiority. Taking the law as the bottom line, we should make full use of early online warning monitoring, off-site supervision, online supervision, reputation mechanism and other measures to promote the innovative development of internet medicine under the framework of legal compliance.

ABSTRACT

The penetration and integration of internet with medical industry is apparently falling behind its interaction with other industries in terms of speed and scale. The main reason is due to the high risk and difficult supervision of internet medicine. Based on the regulatory context, this paper analyzes the endogenous and exogenous risk of internet medicine. The inherent characteristics of the internet (such as openness, diversity, multi subjectivity, virtuality, transparency, and high aggregation) lead to endogenous risks, including jurisdiction disputes, uncertainty of rights and obligations, security of personal information and medical information, monopoly. The lag of specific law in internet medicine, the lack of extensibility and synergy of traditional hierarchical regulatory system, the uncertainty of internet hospital regulatory policy details, the lack of technical specifications/operating procedures and other external system coverage in internet diagnosis and treatment lead to regulatory blind areas and exogenous risks. Based on the risk analysis, this paper discusses further construction of the mechanisms of risk assessment and regulation for internet medicine.

ABSTRACT

Internet medicine is not a concept of jurisprudence. China's current medical law system mainly focuses on main qualifications of the participants who conduct diagnosis and treatment. This paper focuses on several business models of the core element (diagnosis and treatment) in internet medicine, namely: online health consultation provided by internet medical platform, online diagnosis and treatment by internet hospital, and certain artificial intelligence(AI) medicine products that are specialized for diagnosis and treatment. This paper summarizes the development of these three business models, and analyzes the main problems in their development, including the legitimacy identification of online consultation, the dilemma of the development of internet hospitals, the impact of insufficient sample data on the development of medical AI, and the reverse restriction of regulatory difficulties to the development of internet medicine. The next step of developing internet medicine is to broaden the scope of internet diagnosis and treatment on the premise of medical safety, which will be based on the improvement of current regulatory system. It is urgent to build early risk warning system and supervision/ management mechanism for internet medicine.

ABSTRACT

In the fifth scientific and technological revolution, information technology is the first productivity, which has a great impact on the supply and demand of medical services. Generally, internet medicine is equivalent to the combination between health industry and information technology. "Healthy China" strategy is China's "priority development strategy", which adheres to the principle of health equity, emphasizes the integration of health into all policies, and takes co-construction and sharing as the basic path. With implementing internet medicine, "Healthy China" strategy promotes the mobility of medical service with three tools: interconnection, data and artificial intelligence. This enhances the operation efficiency of overall medical and health system, and optimizes the allocation of medical resources. The future development of internet medicine follows the double helix mode driven by technology and policy, and the policy determines the development boundary of the industry. On the basis to ensure medical safety, we should explore the possibility of internet diagnosis and treatment further, and pay attention to the fairness of resource allocation while improving efficiency, so as to realize the co-construction and sharing of health services.

ABSTRACT

Objective:To investigate the expression levels of matrix metalloproteinase-9 (MMP-9), procalcitonin (PCT), soluble triggering receptor expressed on myeloid cells (sTREM-1) and soluble cell differentiation 14 (sCD14) in pregnant women with premature rupture of membranes (PROM) and their predictive value for chorioamnionitis.Methods:A total of 132 pregnant women with PROM who received treatment in Tengzhou Central People's Hospital from January 2016 to June 2017 were included in the study group. These women were assigned to pre-term PROM group (gestational age < 37 weeks, n = 58) and full-term PROM group (gestational age > 37 weeks, n = 74). A total of 106 concurrent full-term healthy pregnant women were included in the control group. Pregnant women in the PROM group were also assigned into an infection group ( n = 51) and a non-infection group ( n = 81). Serum levels of MMP-9, PCT, sTREM-1 and sCD14 were compared between study and control groups, and their value in the diagnosis of PROM complicated with chorioamnionitis was analyzed. Results:The expression levels of MMP-9 [(271.42 ± 34.16) ng/L], PCT [(54.57 ± 8.16) pg/mL], sTREM-1 [(0.51 ± 0.11) ng/mL] and sCD14 [(60.23 ± 9.49) ng/mL] in the study group were significantly higher than those in the control group [(54.97 ± 10.08) ng/L, (26.04 ± 1.98) pg/mL, (0.19 ± 0.04) ng/mL, (42.04 ± 10.33) ng/mL, t = 27.064, 13.767, 14.831, -13.342, all P < 0.01). The expression levels of MMP-9 [(314.05 ± 45.37) ng/L], PCT [(0.61 ± 0.18) ng/mL], sTREM-1 [(63.12 ± 10.12) pg/mL] and sCD14 [(68.07 ± 11.05) ng/mL] in the pre-term PROM group were significantly higher than those in the full-term PROM group [(238.01 ± 40.45) ng/L, (47.87 ± 8.90) pg/mL, (0.43 ± 0.14) ng/mL, (54.09 ± 10.33) ng/mL, t = 9.103, 8.862, -10.538, 6.494, all P < 0.05). The expression levels of MMP-9 [(343.74 ± 43.74) ng/L], PCT [(69.88 ± 8.83) pg/mL], sTREM-1 [(0.67 ± 0.16) ng/mL], sCD14 [(70.41 ± 8.89) ng/mL] in the infection group were significantly higher than those in the non-infection group [(230.09 ± 49.82) ng/L, (45.82 ± 11.04) pg/mL, (0.42 ± 0.19) ng/mL and (54.41 ± 12.42) ng/mL, t = 23.655, 12.014, 9.382, 11.306, all P < 0.01]. The sensitivity (94.23%), specificity (93.75%), positive predictive value (92.45%) and negative predictive value (96.20%) of combined detection of these indexes in the diagnosis of PROM complicated by chorioamnionitis were significantly higher than those of other indexes detected alone (all P < 0.05). Conclusion:Combined detection of serum levels of MMP-9, PCT, sTREM-1 and sCD14 can be used as an effective auxiliary index for the diagnosis of early premature rupture of membranes complicated with chorioamnionitis.

ABSTRACT

Objective:To explore the protective effect of emodin on D-galactosamine (D-GalN)/lipopolysaccharide (LPS)-induced acute liver injury and its mechanism.Methods:A total of 40 male BALB/c mice were randomly (random number) divided into 5 groups ( n=8 in each group): the control group, the emodin group, the D-GalN/LPS group, the emodin+D-GalN/LPS group and the 3-MA+emodin+D-GalN/LPS group. D-GalN (700 mg/kg) and LPS (10 μg/kg) were intraperitoneally injected to induce acute liver injury in mice. Autophagy inhibitor 3-MA (15 mg/kg) and/or emodin (20 mg/kg) were intraperitoneally injected 30 min before the liver injury model. The animals were sacrificed under anaesthesia 6 h after D-GalN/LPS challenge, blood samples and liver tissues were collected. The levels of alanineaminotransferase (ALT) and aspartateaminotransferase (AST) in serum, and myeloperoxidase (MPO) activity of liver tissues were determined by colorimetric quantitative method; the levels of tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were measured by ELISA; the expression of LC3-II and Beclin 1 in the liver tissues were evaluated by Western blot; the pathological changes of liver was evaluated by HE staining. Animal survival rate was also analyzed. The one-way ANOVA was use to compare quantitative data, SNK- q test was used for pairwise comparison between two groups, and Games-Howell test was used when homogeneity of variance were not met. Results:Compared with the control group, the levels of ALT, AST, TNF-α, IL-6 and MPO activity [(2 476.80 ± 263.14) U/L, (271.71 ± 47.15) U/L, (537.92 ± 89.35) pg/mL, (169.74 ± 25.52) pg/mL, and (1.37 ± 0.22) U/mg] were obviously increased in the D-GalN/LPS group ( P<0.05). Compared with the D-GalN/LPS group, the levels of ALT, AST, TNF-α, IL-6 and MPO activity [(1 248.01 ± 380.70) U/L, (142.59 ± 34.63) U/L, (288.91 ± 67.21) pg/mL, (61.83 ± 13.64) pg/mL, and (0.80 ± 0.21) U/mg] were obviously decreased in the emodin+ D-GalN/LPS group ( P<0.05). Compared with the D-GalN/LPS group, the histopathological abnormalities in liver tissue were significantly alleviated and the survival rate of mice was improved in the emodin+ D-GalN/LPS group. Compared with the control group, the expression of LC3-II and Beclin1 was decreased in the liver tissue in the D-GalN/LPS group, while compared with the D-GalN/LPS group, the expression of LC3-II and Beclin1 was increased in the emodin+ D-GalN/LPS group. With co-administration of 3-MA, the protective effects of emodin in acute liver injury were reversed, the levels of AST, ALT, TNF-α, IL-6, and MPO [(2 398.78 ± 233.57) U/L, (242.79 ± 43.46) U/L, (505.07 ± 67.89) pg/mL, (151.46 ± 14.11) pg/mL, and (1.27 ± 0.15) U/mg] were increased, and the pathological damage of liver tissue was aggravated. Conclusions:Emodin alleviates D-GalN/LPS-induced acute liver injury in mice, which may be related to the activation of protein LC3-II, Beclin1 and restored autophagy.

ABSTRACT

The global morbidity and mortality of cardiovascular diseases remain high. Atherosclerosis is an important pathological basis of cardiovascular diseases, and its pathogenic mechanism has not been fully clarified. It was reported that pathogenic mechanism of atherosclerosis is related to vascular endothelial cell injury, lipid metabolism disorder, inflammatory reaction, imbalance between autophagy and apoptosis, et al. Traditional Chinese medicine(TCM) formula has shown good effects in the prevention and treatment of atherosclerosis. There are a lot of studies that showed the anti-atherosclerosis effect and the mechanism of TCM formula. In this paper, we reviewed the mechanism of anti-atherosclerosis action of TCM formula by summarizing the research literatures in the past five years, and provide reference for the further systematic study of anti-atherosclerosis effect of TCM formula.

ABSTRACT

@#Objective    To investigate the perioperative results and safety of minimally invasive direct coronary artery bypass grafting (MIDCAB) treatment of anterior descending artery disease through a small left thoracic incision assisted by thoracoscopy. Methods    The clinical data of 92 patients who received MIDCAB in our hospital from May 2014 to October 2018 were retrospectively analyzed, including 72 (78.26%) males aged 42-78 (61.2±7.48) years, and 20 (21.74%) females aged 30-80 (61.30±12.26) years. The perioperative complications, blood product use, left heart function changes, ventilator use time, ICU stay, hospital stay and other indicators were analyzed. Results    Two (2.17%) patients were transferred to thoracotomy, 5 (5.43%) patients received blood products during the operation, 2 (2.17%) were subjected to secondary thoracotomy to stop bleeding, 4 (4.34%) had postoperative hypoxemia and 1 (1.08%) was reintubated. The ventilator use time was 3-227 (22.35±35.39) hours, the ICU stay was 16-777 (78.85±108.62) hours, and the postoperative hospital stay was 2-36 (8.86±6.05) days. One (1.08%) patient died in hospital. Conclusion    MIDCAB for anterior descending artery disease has good perioperative results, especially for solitary anterior descending artery disease, which can reduce the use of blood products, and shorten the time of ventilator use after operation, ICU stay and hospital stay.

ABSTRACT

Objective:To investigate the clinical efficacy of Dog-Bone double button in the treatment of acute acromioclavicular dislocation under shoulder arthroscopy.Methods:A retrospective analysis was conducted of the 20 patients with acute acromioclavicular dislocation who had been treated at Department of Sports Medicine, Northern Jiangsu People's Hospital of Jiangsu Province from November 2018 to December 2020 by Dog-Bone double button under shoulder arthroscopy. They were 11 males and 9 females, aged from 31 to 63 years. Recorded were their visual analogue scale (VAS), Constant-Murley shoulder function score and range of shoulder anteflexion at preoperation and the last follow-up, as well as complications and the X-ray parameters at one month postoperation and the last follow-up [including coracoclavicular distance (CCD), distance between the upper and lower Dog-Bone titanium plates (DDD), angle between the coracoid process tunnel and the tangent line of the superior clavicle (CTCA), and widths of the clavicle tunnel and the coracoid process tunnel].Results:The 20 patients were followed up for 6 to 12 months (average, 10.5 months). Their preoperative VAS score, Constant score, and range of shoulder anteflexion were 3.0 (3.0, 4.0), 57.0 (54.3, 61.5) and 130° (110°, 140°), which were significantly improved to 0 (0, 0.8), 90.0 (86.5, 91.0) and 170° (170°, 180°) at the last follow-up ( P<0.05). Their CCD, DDD, CTCA, and widths of the clavicle tunnel and the coracoid process at one month postoperation were (5.0±1.0) mm, (32.4±3.5) mm, 91.7° (88.5°, 104.9°), 3.0 (3.0, 3.0) mm and 3.0 (3.0, 3.0) mm, which were significantly improved to (6.3±1.3) mm, (32.8±3.7) mm, 84.8° (81.8°, 92.0°), 3.5 (3.4, 3.6) mm and 3.2 (3.1, 3.3) mm with the exception of DDD at one month postoperation ( P<0.05). The last follow-up observed postoperative reduction loss in only one patient. Conclusion:For acute acromioclavicular joint dislocation, the Dog-Bone fixation technique under shoulder arthroscopy can lead to fine surgical efficacy and patient satisfaction, because it has advantages of limited trauma, good functional recovery of the shoulder, and effective prevention of reduction loss.

ABSTRACT

The aim of the present study was to investigate the effects of dexmedetomidine (DEX) on acute liver injury induced by lipopolysaccharide (LPS)/D-galactosamine (D-Gal) and the underlying mechanism. Male BALB/c mice were intraperitoneally injected with LPS/D-Gal to induce acute liver injury model, and pretreated with DEX or in combination with the autophagy inhibitor, 3-methyladenine (3-MA) 30 min before injection. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activity, as well as myeloperoxidase (MPO) activity in liver tissue were determined with the corresponding kits. Serum tumor necrosis factor α (TNF-α) and interleukin-6 (IL-6) levels were determined by ELISA. The protein expression levels of LC3-II and P62 in liver tissue were determined by Western blot. Liver histopathological changes were detected by HE staining. The results showed that, compared with control group, LPS/D-Gal enhanced ALT and AST activity, increased TNF-α and IL-6 levels, as well as MPO activity, up-regulated LC3-II and P62 protein expression levels, and significantly induced pathological damage in liver tissue. DEX reversed the above changes in the LPS/D-Gal group, whereas these protective effects of DEX were blocked by 3-MA. The above results suggest that DEX alleviates LPS/D-Gal-induced acute liver injury, which may be associated with the up-regulation of LC3-II protein expression and the activation of autophagy.

ABSTRACT

Objective:To investigate the causes of secondary glaucoma after vitrectomy for familial vitreous amyloidosis associated with transthyretin (TTR) gene Gly83Arg mutation.Methods:A retrospective case study. From January 2008 to January 2020, 13 cases (23 eyes) with hereditary vitreous amyloidosis and treated by vitrectomy in the Affiliated Hospital of Zunyi Medical University were collected. Among them, there were 7 males with 12 eyes and 6 females with 11 eyes. The average age was 43.0±4.8 years. All the affected eyes underwent standard three-channel vitrectomy through the flat part of the ciliary body. According to whether complete vitreous detachment (PVD) was formed during the operation, it was divided into complete PVD group and incomplete PVD group; according to the occurrence time of secondary glaucoma and vitreous amyloidosis after surgery, it was divided into 1-12 months group and 13-36 months group, >37 months group. The average follow-up time after surgery was 36.7±6.0 months. The incidence of secondary glaucoma and the recurrence rate of vitreous amyloidosis between groups were compared by χ2 test; the correlation between recurrence of vitreous amyloidosis and secondary glaucoma after surgery was analyzed by Spearman rank correlation analysis. Results:Among the 23 eyes, there were 8 eyes in the complete PVD group and 15 eyes in the incomplete PVD group, respectively. Vitreous amyloidosis recurred in 15 eyes (65.22%, 15/23) after surgery. There were 14 (93.30%, 14/15) and 1 (6.70%, 1/15) eyes in the incomplete PVD group and the complete PVD group, respectively; the comparison of the recurrence rate of vitreous amyloidosis between the two groups was statistically significant ( χ2=11.676, P<0.01). 1-12 months group, 13-36 months group, >37 months group included 1 (4.35%, 1/23), 12 (52.17%, 12/23), 2 (8.70%, 2/23) Only eye. The recurrence rate in the 13-36 months group was significantly higher than that in the 1-12 months group and >37 month group. Secondary glaucoma occurred in 11 eyes (47.80%, 11/23) after surgery. 1-12 months group, 13-36 months group, above 37 months group were 1 (4.35%, 1/23), 8 (34.78%, 8/23), 2 (8.70%, 2/23) eyes. The incidence of secondary glaucoma in the 13-36 months group was higher than that in the 1-12 months group and >37 months group. Among 11 eyes with secondary glaucoma, 10 eyes had recurrence of vitreous amyloidosis after surgery, and 1 eye had no recurrence. The results of Spearman rank correlation analysis showed that there was a positive correlation between the recurrence of vitreous amyloidosis and the occurrence of secondary glaucoma ( rs=0.516, P=0.012). Conclusion:The incidence of secondary glaucoma after vitrectomy in a family with vitreous amyloidosis caused by the Gly83Arg mutation of TTR gene is higher, and its occurrence is significantly positively correlated with the recurrence of vitreous amyloidosis.
