Objective:To compare the changes in pelvic floor electrophysiology and imaging in female patients with myofascial pelvic pain (MFPP), and to explore the characteristics and significance of these changes.Methods:A total of 49 MFPP patients who were admitted to the of Dalian Women′s and Children′s Medical Center (Group) from January 2019 to October 2021 were randomly selected as the research group, and 41 healthy women during the same period were selected as the control group. Both groups filled in the center′s medical history and general condition survey form. French PHENIX series pelvic floor muscle potential detection instrument was used to detect the resting vaginal muscle potential and maximum muscle potential of the two groups. The static tension, dynamic tension and pelvic floor muscle contraction force of the two groups were measured by French PHENIX series electronic tensioning apparatus with 5° and 10° opening respectively. Two dimensional transperineal ultrasound and three dimensional transvaginal ultrasound produced by B-K Company in Denmark were used to measure the length between the lower margin of the bladder neck from the symphysis pubis and the bladder neck and the bladder bottom (BND, BSD), the diameter of the genital tract hiatus and the angle of the anus and rectum. The area, anterior-posterior diameter, transverse diameter and different damage degrees of levator ani levator were measured.Results:The resting muscle potential of the study group was higher than that of the control group: 2 μV vs. 1 μV ( P<0.05); the maximum vaginal myopotential was higher than that of the control group: 7 μV vs. 6 μV ( P<0.05). The static tension, dynamic tension and contractile force: 204 g/m 2 vs. 175 g/m 2, 450 g/m 2 vs. 410 g/m 2 and 237 g/m 2 vs. 51 g/m 2 of pelvic floor muscle in the study group were higher than those in the control group when the tensioner was opened for 5° ( P<0.05). In resting state, BND, BSD and reproductive tract hiatus diameter in the study group were smaller than those in the control group: 14.0 mm vs. 16.7 mm, 15.3 mm vs. 19.7 mm, 46.7 mm vs. 49.5 mm ( P<0.05). The anal angle was greater than that of the control group: 129° vs. 112° ( P<0.05). The anal right angle in the study group was greater than that in the control group: 113° vs. 109° ( P<0.05). In the resting state, the area of levator ANI hiatus: 10.1 cm 2 vs. 11.6 cm 2, anterior and posterior diameters: 44.2 mm vs. 47.4 mm, transverse diameters and the defect scores of levator ani in the study group were all smaller than those in the control group ( P<0.05). Conclusions:MFPP presents with persistent pelvic floor muscle spasm and loss of coordination. MFPP can be treated by spasmolysis of pelvic floor muscle and fascia, which provides reference value for clinical treatment.

Objective:To integrate the best evidence of non-drug intervention of urinary incontinence in elderly women and to formulate practical recommendations.Methods:In this systematic review study, using “elderly woman”,“urinary incontinence”,“bladder training”,“pelvic floor muscle training”,“enuresis”,“leakage of urine” as the key words, the 6S evidence resource pyramid model was used to search in British Medical Journal best practice, Uptodate, World Health Organization, Guidelines International Network, National Institute for Health and Care Excellence, Chinese Medical Association, Scottish Intercollegiate Guideline Network, Registered Nurses Association of Ontario, Cochrane Library, The Joanna Briggs Institute (JBI), New Zealand Guidelines Group, Polish Society of Gynecologists and Obstetricians, PubMed, Embase, Medline, Web of Science, SinoMed, China National Knowledge Infrastructure, WanFang Data, etc. The evidence retrieved included evidence-based knowledge base resources, clinical practice guidelines, expert consensus, systematic review, etc. Data were retrieved from January 1, 2017 to May 1, 2022, and collated from May 2, 2022 to May 25, 2022. Two researchers independently evaluated the quality of literature and extracted data using the AGREE Ⅱ and JBI evidence-based health care center assessment tools. The JBI evidence-based health care center′s evidence pre-rating system and evidence recommendation rating system were applied to rank the evidence; and under the guidance of the evidence structure of JBI, the strength of evidence recommendation was determined and the best evidence was extracted and summarized in combination with the study group discussion and expert opinion.Results:A total of 9 articles were retrieved, including 7 guidelines and 2 systematic reviews; and 6 guidelines were classified as Grade A and 1 as grade B; both 2 systematic reviews were rated as Grade A; 84% (27/32) of the items were evaluated as “Yes”. Evidence were summarized as 34 pieces of best evidence from 6 dimensions, including “overall recommendation, evaluation of type and degree of urinary incontinence, lifestyle change, behavioral therapy, prevention of precipitating factors, intervention in special population”; the flow chart of screening, evaluation, special symptoms, life style and behavior therapy was combed, and the practical suggestions were formed.Conclusions:The overall quality of the literature on non-drug intervention of urinary incontinence in elderly women is high, and the level of evidence is high. Early identification of urinary incontinence types and assessment of disease severity, lifestyle changes, avoidance of predisposing factors and behavioral therapy are the key to non-drug treatment of urinary incontinence in those patients.

Nonalcoholic steatohepatitis (NASH) is a spectrum of chronic liver disease characterized by hepatic lipid metabolism disorder. Recent reports emphasized the contribution of triglyceride and diglyceride accumulation to NASH, while the other lipids associated with the NASH pathogenesis remained unexplored. The specific purpose of our study was to explore a novel pathogenesis and treatment strategy of NASH via profiling the metabolic characteristics of lipids. Herein, multi-omics techniques based on LC-Q-TOF/MS, LC-MS/MS and MS imaging were developed and used to screen the action targets related to NASH progress and treatment. A methionine and choline deficient (MCD) diet-induced mouse model of NASH was then constructed, and Schisandra lignans extract (SLE) was applied to alleviate hepatic damage by regulating the lipid metabolism-related enzymes CES2A and CYP4A14. Hepatic lipidomics indicated that MCD-diet led to aberrant accumulation of phosphatidylethanolamines (PEs), and SLE could significantly reduce the accumulation of intrahepatic PEs. Notably, exogenous PE (18:0/18:1) was proved to significantly aggravate the mitochondrial damage and hepatocyte apoptosis. Supplementing PE (18:0/18:1) also deteriorated the NASH progress by up regulating intrahepatic proinflammatory and fibrotic factors, while PE synthase inhibitor exerted a prominent hepatoprotective role. The current work provides new insights into the relationship between PE metabolism and the pathogenesis of NASH.

AIM: To observe the effect ofacacia honey (AH) on serum uric acid level and renal function in potassium oxonate modelrats after drinking AH aqueous solution. METHODS: Sixty male SD rats were selected and randomly divided into control group (CON group), potassium oxonate model group (OA model group), 10% fructose group (10% F group) and different concentration honey groups (25%, 12.5% and 6.25% AH groups). All rats were fed with normal diet.The rats in CON group were subcutaneously injected with 5% sodium carboxymethyl cellulose (CMC-Na) solution and drunk sterile water every day, while rats in other groups were injected with 100 mg / kg OA solution suspended with 5% CMC-Na subcutaneouslyand drunksterile water orfructose solution or AH solution of different concentrations every day. Before and during the 4-week test, rats were weighed and blood was taken once a week. At the end of test, urine and feces specimens or kidney tissues were collected and blood was taken from the abdominal aorta. The uric acid content in blood, urine, and feces and the levels of serum creatinine (Cre) and blood urea nitrogen (BUN) or inflammatory factors in kidney tissues were measured. Renal function and histology were evaluated. RESULTS: Compared with CON group, AH could significantly reduce the body weight of rats (P<0.05), increase the kidney organ coefficient, the levels of serum uric acid, and uric acid in urine or feces, and reduce the level of fecal uric acid (FUA) in rats. AH can down regulate the level of tumor necrosis factor alpha (TNF-a) (P< 0.05) and up regulate the expression of monocyte chemoattractant protein 1 (MCP-1) and transforming growth factor β - 1 (TGF - β1) in rats kidneys; AH can cause slight to mild dilatation of renal tubules and mild to moderate basophilic lesions of renal rubules in rat kidney in a dose dependent manner. CONCLUSION: In the doses rang of present study, AH can cause hyperuricemia, renal tubular dilatation and basophilic lesions, and lead to renal function damage in rats.

Immune escape mechanisms in non-small cell lung cancer (NSCLC) can disrupt every step of the anti-cancer immune response. In recent years, an increased understanding of the specific mechanisms fueling immune escape has allowed for the development of numerous immunotherapeutic treatments that have been introduced into the clinical practice. The advent of immunotherapy has dramatically changed the current treatment landscape of advanced or metastatic NSCLC because of its durable efficacy and manageable toxicity. In this review, we will first present a brief overview of recent evidence on immune escape mechanisms in NSCLC. We will then discuss the current promising immunotherapeutic strategies in advanced or metastatic NSCLC tumors.

Parkin, an E3 ubiquitin ligase, plays a role in maintaining mitochondrial homeostasis through targeting damaged mitochondria for mitophagy. Accumulating evidence suggests that the acetylation modification of the key mitophagy machinery influences mitophagy level, but the underlying mechanism is poorly understood. Here, our study demonstrated that inhibition of histone deacetylase (HDAC) by treatment of HDACis activates mitophagy through mediating Parkin acetylation, leading to inhibition of cervical cancer cell proliferation. Bioinformatics analysis shows that Parkin expression is inversely correlated with HDAC2 expression in human cervical cancer, indicating the low acetylation level of Parkin. Using mass spectrometry, Parkin is identified to interact with two upstream molecules, acetylase acetyl-CoA acetyltransferase 1 (ACAT1) and deacetylase HDAC2. Under treatment of suberoylanilide hydroxamic acid (SAHA), Parkin is acetylated at lysine residues 129, 220 and 349, located in different domains of Parkin protein. In in vitro experiments, combined mutation of Parkin largely attenuate the interaction of Parkin with PTEN induced putative kinase 1 (PINK1) and the function of Parkin in mitophagy induction and tumor suppression. In tumor xenografts, the expression of mutant Parkin impairs the tumor suppressive effect of Parkin and decreases the anticancer activity of SAHA. Our results reveal an acetylation-dependent regulatory mechanism governing Parkin in mitophagy and cervical carcinogenesis, which offers a new mitophagy modulation strategy for cancer therapy.
