Benign Multicystic Peritoneal Mesothelioma: A Case Report

Benign multicystic peritoneal mesothelioma(BMPM)is a rare tumor originating from peritoneal mesothelial cells.Here,we present a case of an 18-year-old male with right lower abdominal pain.Physical examination revealed a palpable mass with unclear boundaries.Laboratory tests showed elevated levels of monocytes and high-sensitivity C-reactive protein.CT scan revealed a cystic mass in the ileocecal region with multiple septations.Laparoscopic surgery confirmed a cystic solid mass resembling beads on the colon’s right side.Immunohistochemistry confirmed BMPM diagnosis.BMPM,especially in the ileocecal region,is uncommon and presents diagnostic challenges.Differential diagnosis includes lymphangioma,peritoneal metastasis,and malignant mesothelioma.CT findings,such as thin cyst walls and septations,aid in diagnosis.Recognition of BMPM’s imaging features improves diagnostic accuracy.Surgical resection remains the primary treatment.This case underscores the importance of considering BMPM in young male patients with abdominal pain and emphasizes the value of imaging modalities in accurate diagnosis and management.

Ultrasound-guided paravertebral nerve block anesthesia on the stress response and hemodynamics among lung cancer patients

BACKGROUND Thoracic surgery for radical resection of lung tumor requires deep anesthesia which can lead to an adverse inflammatory response,loss of hemodynamic stability,and decreased immune function.Herein,we evaluated the feasibility and benefits of ultrasound-guided paravertebral nerve block anesthesia,in combination with general anesthesia,for thoracic surgery for lung cancer.The block was performed by diffusion of anesthetic drugs along the paravertebral space to achieve unilateral multi-segment intercostal nerve and dorsal branch nerve block.AIM To evaluate the application of ultrasound-guided paravertebral nerve block anesthesia for lung cancer surgery to inform practice.METHODS The analysis was based on 140 patients who underwent thoracic surgery for lung cancer at our hospital between January 2018 and May 2020.Patients were randomly allocated to the peripheral+general anesthesia(observation)group(n=74)or to the general anesthesia(control)group(n=66).Patients in the observation group received ultrasound-guided paravertebral nerve block anesthesia combined with general anesthesia,with those in the control group receiving an epidural block combined with general anesthesia.Measured outcomes included the operative and anesthesia times,as well as the mean arterial pressure(MAP),heart rate(HR),and blood oxygen saturation(SpO;)measured before surgery,15 min after anesthesia(T1),after intubation,5 min after skin incision,and before extubation(T4).RESULTS The dose of intra-operative use of remifentanil and propofol and the postoperative use of sufentanil was lower in the observation group(1.48±0.43 mg,760.50±92.28 mg,and 72.50±16.62 mg,respectively)than control group(P<0.05).At the four time points of measurement(T1 through T4),MAP and HR values were higher in the observation than control group(MAP,90.20±9.15 mmHg,85.50±7.22 mmHg,88.59±8.15 mmHg,and 90.02±10.02 mmHg,respectively;and HR,72.39±8.22 beats/min,69.03±9.03 beats/min,70.12±8.11 beats/min,and 71.24±9.01 beats/min,respectively;P<0.05).There was no difference in SpO;between the two groups(P>0.05).Postoperative levels of epinephrine,norepinephrine,and dopamine used were significantly lower in the observation than control group(210.20±40.41 pg/mL,230.30±65.58 pg/mL,and 54.49±13.32 pg/mL,respectively;P<0.05).Similarly,the postoperative tumor necrosis factor-αand interleukin-6 levels were lower in the observation(2.43±0.44 pg/mL and 170.03±35.54 pg/mL,respectively)than control group(P<0.05).There was no significant difference in the incidence of adverse reactions between the two groups(P>0.05).CONCLUSION Ultrasound-guided paravertebral nerve block anesthesia improved the stress and hemodynamic response in patients undergoing thoracic surgery for lung cancer,with no increase in the rate of adverse events.

MiR-205 mediated APC regulation contributes to pancreatic cancer cell proliferation

BACKGROUND Pancreatic cancer is a deadly malignancy with aggressive properties. MicroRNAs (miRNAs) participate in the pathogenesis of a variety of diseases and molecular processes by targeting functional mRNAs. Nevertheless, the regulatory role of miRNAs in signaling pathways involved in pancreatic cancer remains largely unknown. AIM To explore the molecular regulation involved in pancreatic cancer and potential mechanisms of miR-205. METHODS Microarray analysis was performed to investigate the expression profile of miRNAs in pancreatic cancer. Expression of miR-205 was validated by qRT-PCR. Target prediction and functional enrichment analysis were employed to seek potential target genes of miR-205 and potential functions of these genes. The target binding of miR-205 and adenomatous polyposis coli (APC) was validated by luciferase reporter assay. APC protein expression in pancreatic cancer was validated by qRT-PCR and Western blot. Proliferation was evaluated by MTT and colony formation assays. RESULTS A large number of miRNAs with altered expression were identified in pancreatic cancer. MiR-205 was significantly up-regulated. APC was found to be a validated target of miR-205 and down-regulated in pancreatic cancer. Proliferation experiments showed that miR-205 could promote cell proliferation in pancreatic cancer by targeting APC. CONCLUSION The above findings suggested that miR-205 mediated APC regulation contributes to pancreatic cancer development, which could be considered as a novel prognostic biomarker for clinical care.

The relationship between acceptance of illness and quality of life among men who have sex with men living with human immunodeficiency virus:A cross-sectional study

Objectives To explore the relationship between acceptance of illness and quality of life(QOL),and factors associated with acceptance of illness among men who have sex with men(MSM)living with human immunodeficiency virus(HIV).Methods Three hundred and one MSM were recruited from an HIV clinic between August and December 2018.The battery of measurements consisted of the Acceptance of Illness Scale,World Health Organization Quality of Life Questionnaire for HIV brief version,HIV Cognitive Appraisal Scale and a self-designed questionnaire used to collect general information.Pearson correlation test was used to examine the relationship between acceptance of illness and QOL.Univariate and multivariate ordinal logistic regression analyses were used to examine whether the general data(demographic and HIV-related clinical data)and HIV cognitive appraisal were associated with acceptance of illness levels.Results Descriptive analysis showed the acceptance level among MSM living with HIV was moderate(Mean=26.29,SD=5.28).Those with a better acceptance of illness had a better QOL(r=0.69,P<0.01).In the multivariate ordinal logistic regression model,education level,threat appraisals(OR:1.09;95%CI[1.06–1.13]),and controllability appraisals(OR:0.82;95%CI[0.71–0.94])were significantly associated with acceptance of illness.Conclusions Results showed acceptance level was moderate and had a positive correlation with QOL.High level of education,low threat appraisals and high controllability appraisals were related to high illness acceptance.This finding highlights the importance of focusing on HIV-infected MSM with low education and on their perceptions of threat and controllability about HIV-related issues when designing interventions to promote illness acceptance in this vulnerable population.

Atorvastatin ameliorated myocardial fibrosis in db/db mice by inhibiting oxidative stress and modulating macrophage polarization

BACKGROUND People with diabetes mellitus(DM)suffer from multiple chronic complications due to sustained hyperglycemia,especially diabetic cardiomyopathy(DCM).Oxidative stress and inflammatory cells play crucial roles in the occurrence and progression of myocardial remodeling.Macrophages polarize to two distinct phenotypes:M1 and M2,and such plasticity in phenotypes provide macrophages various biological functions.AIM To investigate the effect of atorvastatin on cardiac function of DCM in db/db mice and its underlying mechanisms.METHODS DCM mouse models were established and randomly divided into DM,atorvastatin,and metformin groups.C57BL/6 mice were used as the control.Cardiac function was evaluated by echocardiography.Hematoxylin and eosin and Masson staining was used to examine the morphology and collagen fibers in myocardial tissues.The expression of transforming growth factor-β1(TGF-β1),tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),M1 macrophages(iNOS^(+)),and M2 macrophages(CD206^(+))were demonstrated by immunohistochemistry and immunofluorescence staining.The levels of TGF-β1,IL-1β,and TNF-αwere detected by ELISA and real-time quantitative polymerase chain reaction.Malondialdehyde(MDA)concentrations and superoxide dismutase(SOD)activities were also measured.RESULTS Treatment with atorvastatin alleviated cardiac dysfunction and decreased db/db mice. The broken myocardialfibers and deposition of collagen in the myocardial interstitium were relieved especially by atorvastatin treatment.Atorvastatin also reduced the levels of serum lactate dehydrogenase, creatine kinase isoenzyme, and troponin;lowered the levels of TGF-β1, TNF-α and IL-1β in serum and myocardium;decreased the concentration of MDAand increased SOD activity in myocardium of db/db mice;inhibited M1 macrophages;and promoted M2macrophages.CONCLUSION Administration of atorvastatin attenuates myocardial fibrosis in db/db mice, which may be associated with theantioxidative stress and anti-inflammatory effects of atorvastatin on diabetic myocardium through modulatingmacrophage polarization.

Role of LM23 in cell proliferation and apoptosis and its expression during the testis development

LM23, a gene expressed specifically in the testis in a stage-specific manner, has a diverse range of functions that are important in both the life and death of spermatogenic cells. The aim of this study was to further investigate the expression of LM23 in the developing rat testis and the biological function of LM23 in proliferation and antiapoptosis in vitro. Semiquantitative reverse transcription （RT）-PCR and real-time PCR were used to examine the expression of LM23 in testis at different developmental stages. The results suggested that LM23 mRNA levels in the testis increased progressively after birth. The role of LM23 in proliferation was analyzed with cell counting kit-8 （CCK8）, colony-forming efficiency （CFE） and flow cytometry assays. The results indicated that ectopic expression of LM23 in 293T cells significantly promoted cell proliferation by increasing cell numbers in S phase. Several methods were used, including CCK8, annexin V and propidium iodide staining and western blotting, to determine the role of LM23 in apoptosis. The results showed that LM23 played a protective role in H202-induced apoptosis of 293T cells, mediated at least in part through the Akt/PI3K signal pathway. Taken together, these results provide new insights into the role of LM23 in the development of the testes andspermatogenesis.

Static analysis of tympanic membrane in aero-otitis media by three-dimensional model of the middle ear

The three-dimensional(3D)model of the middle ear is of great significance to the research of middle ear related diseases.The particular focus of this work is to simulate the impact of aircraft altitude and speed changes on the tympanic membrane(TM)during the descent phase,so as to analyze the pathogenesis of aero-otitis media and the mechanical response characteristics of TM under static pressure.The simulations showed that the stress and strain of TM increase as the altitude difference and speed of the aircraft increase,and the maximum stress and strain areas are consistent with the clinical observation of TM hyperemia.Therefore,among many prevention and treatment measures of aero-otitis media,it is a therapeutic method to directly balance the pressure difference between the inner and outer TM.

Real world effectiveness of PCSK-9 inhibitors combined with statins versus statins-based therapy among patients with very high risk of atherosclerotic cardiovascular disease in China(RWE-PCSK study)

BACKGROUND The efficacy and safety of proprotein convertase subtilisin/kexin type 9(PCSK-9) inhibitors were confirmed by several clinical trials, but its effectiveness in routine clinical practice in China has not been evaluated. This study aims to describe the real world effectiveness of PCSK-9 inhibitors combined with statins compared with statins-based therapy among patients with very high risk of atherosclerotic cardiovascular disease(ASCVD).METHODS This is a multi-center observational study, enrolled patients from 32 hospitals who underwent percutaneous coronary intervention(PCI) from January to June in 2019. There are 453 patients treated with PCSK-9 inhibitors combined with statins in PCSK-9 inhibitor group and 2,610 patients treated with statins-based lipid lowering therapies in statins-based group. The lipid control rate and incidence of major adverse cardiovascular events(MACE) over six months were compared between two groups.A propensity score-matched(PSM) analysis was used to balance two groups on confounding factors. Survival analysis using Kaplan-Meier methods was applied for MACE.RESULTS In a total of 3,063 patients, 89.91% of patients had received moderate or high-intensity statins-based therapy before PCI, but only 9.47% of patients had low-density lipoprotein cholesterol(LDL-C) levels below 1.4 mmol/L at baseline. In the PSM selected patients, LDL-C level was reduced by 42.57% in PCSK-9 inhibitor group and 30.81%(P < 0.001) in statins-based group after six months. The proportion of LDL-C ≤ 1.0 mmol/L increased from 5.29% to 29.26% in PCSK-9 inhibitor group and 0.23% to 6.11% in statins-based group, and the proportion of LDL-C ≤ 1.4 mmol/L increased from 10.36% to 47.69% in PCSK-9 inhibitor group and 2.99% to 18.43% in statins-based group(P < 0.001 for both). There was no significant difference between PCSK-9 inhibitor and statins-based treatment in reducing the risk of MACE(hazard ratio = 2.52, 95% CI: 0.49-12.97, P = 0.250).CONCLUSIONS In the real world, PCSK-9 inhibitors combined with statins could significantly reduce LDL-C levels among patients with very high risk of ASCVD in China. The long-term clinical benefits for patients received PCSK-9 inhibitor to reduce the risk of MACE is still unclear and requires further study.
