RESUMEN

Glucagon-like peptide-1 ( GLP-1 ) is secreted by gut enteroendocrine cells. GLP-1 receptor agonists ( GLP-1 RAs) control glucose-related augmentation of insulin and suppress glu-cagon secretion. GLP-lRAs also inhibit gastric emptying, food intake and limit weight gain. In the past decade, significant progresses have been made in the investigation on the effects of GLP-1 RAs on cardiovascular system. The potential advantages of oral small-molecule GLP-1 RAs could improve the application of this class of drugs. This review highlights the multiple cardiovascular profiles of GLP-1 RAs in the treatment of cardiovascular diseases to provide new insights into cardiovascular benefits of GLP-1 RAs.

RESUMEN

PURPOSE: This study was designed to explore the effects of interleukin 33 (IL-33) on the progression of atherosclerosis and the possible mechanism. METHODS: The adhesion assay was performed on isolated peripheral blood mononuclear cells (PBMCs) and human umbilical vein endothelial cells (HUVEC). The expression of proteins and messenger RNA (mRNA) were detected by western blot and quantitative real-time polymerase chain reaction (PCR), including intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and P-selectin. The effect of IL-33 on the interaction of growth stimulation expressed gene 2 (ST2) with myeloid differentiation factor 88 (MyD88) and interleukin-1 receptor-associated kinase (IRAK) 1/4 were investigated using co-immunoprecipitation assay. An apolipoprotein (Apo) E-/- mice model was used to confirm the effect of IL-33 on atherosclerosis progression. Area of plaques was recorded by hematoxylin-eosin (H&E) staining. The severity of atherosclerosis plaque was evaluated using immunohistochemistry assay, and lipid accumulation was measured by an oil red O staining. In contrast, western blot was performed to detect the expression levels of VCAM-1, extracellular signal-regulated kinase (ERK) 1/2, and interferon regulatory factor 1 (IRF1). RESULTS: Our study observed that IL-33 suppressed cell adhesion and the expression of VCAM-1 in tumor necrosis factor-α (TNF-α) exposed HUVEC. Moreover, the addition of IL-33 significantly inhibited the expression of IRF1 and the binding level of IRF1 to VCAM-1 and also promoted the phosphorylation level of IRAK1/4 and ERK1/2 compared to TNF-α-stimulated HUVEC. The ST2 neutralizing antibody or ERK pathway inhibitor SCH772984 reversed the regulatory effects of IL-33 on HUVEC, suggesting that IL-33 suppressed IRF1 and VCAM-1 dependent on binding to ST2 and activating the ERK1/2 signaling pathway. Further investigation in vivo confirmed that IL-33 decreased the expressions of IRF1 and VCAM-1 by activating the phosphorylation of ERK1/2 in the thoracic aorta of Apo E-/- mice. CONCLUSION: In conclusion, our results demonstrated that IL-33 plays a protective role in the progression of atherosclerosis by inhibiting cell adhesion via the ERK1/2-IRF1-VCAM-1 pathway. This study may provide a potential therapeutic way to prevent the development of atherosclerosis.

RESUMEN

The highly conserved ribosomal protein L34 (RPL34) has been reported to play an essential role in the progression of diverse malignancies. RPL34 is aberrantly expressed in multiple cancers, although its significant in colorectal cancer (CRC) is currently unclear. Here, we demonstrated that RPL34 expression was higher in CRC tissues than in normal tissues. Upon RPL34 overexpression, the ability of proliferation, migration, invasion, and metastasis of CRC cells were significantly enhanced in vitro and in vivo. Furthermore, high expression of RPL34 accelerated cell cycle progression, activated the JAK2/STAT3 signaling pathway, and induced the epithelial-to-mesenchymal transition (EMT) program. Conversely, RPL34 silencing inhibited the CRC malignant progression. Utilizing immunoprecipitation assays, we identified the RPL34 interactor, the cullin-associated NEDD8-dissociated protein 1 (CAND1), which is a negative regulator of cullin-RING ligases. CAND1 overexpression reduced the ubiquitin level of RPL34 and stabilized RPL34 protein. CAND1 silencing in CRC cells resulted in a decrease in the ability of proliferation, migration, and invasion. CAND1 overexpression promoted CRC malignant phenotypes and induced EMT, and RPL34 knockdown rescued CAND1-induced CRC progression. In summary, our study indicates that RPL34 acts as a mediator, is stabilized by CAND1, and promotes proliferation and metastasis, in part, through the activation of the JAK2/STAT3 signaling pathway and induction of EMT in CRC.

RESUMEN

Objective: This study explored the relationship between college students' physical activity motivation and exercise behavior and constructed a chain mediation model through the mediating roles of exercise climate and exercise self-efficacy. Methods: By random sampling, 1,032 college students were investigated using the Exercise Motivation Scale, Physical Exercise Rating Scale, Exercise Climate Scale, and Exercise Self-Efficacy Scale. Results: (1) There was a huge positive correlation between exercise motivation and exercise behavior (r = 0.240, p < 0.01), and the immediate ways of linking exercise motivation to exercise behavior were critical (ß = 0.068, t = 0.040, p < 0.01). (2) Exercise motivation could positively predict exercise climate (ß = 0.373, t = 0.061, p < 0.01) and exercise self-efficacy (ß = 0.174, t = 0.039, p < 0.01), and exercise climate could emphatically foresee exercise behavior (ß = 0.302, t = 0.051, p < 0.01). Exercise self-efficacy could foresee exercise behavior decidedly (ß = 0.190, t = 0.048, p < 0.01). (3) Exercise climate and exercise self-efficacy play a critical intervening role between exercise motivation and exercise behavior. The intercession impact is explicitly made out of aberrant impacts created in three ways: exercise motivation → exercise climate → exercise behavior (mediating effect value: 0.113); exercise motivation → exercise self-efficacy → exercise behavior (mediating effect value: 0.033); exercise motivation → exercise climate → exercise self-efficacy → exercise behavior (mediating effect value: 0.027). Conclusion: (1) Exercise climate, exercise self-efficacy, and exercise behavior can all be significantly predicted by exercise motivation, suggesting that exercise motivation may help to enhance these variables. (2) In addition to having a direct impact on exercise behavior, exercise motivation can also have an indirect impact through the separate mediating effects of exercise climate and exercise self-efficacy as well as the chain mediating effect of exercise climate and exercise self-efficacy, which is crucial for encouraging college students to engage in physical activity.

RESUMEN

BACKGROUND: A magnetic ball is a toy for children that can cause physical injury when used improperly. The injury of urethra and bladder caused by magnetic ball is rarely reported. CASE: Here we present a case of self-inflicted intravesical insertion of 83 magnetic balls by a 10-year-old boy. Preliminary diagnosis was made by a plain radiograph of the pelvis and ultrasonic examination of bladder and all the magnetic balls were removed under cystoscopy successfully. CONCLUSIONS: For children with recurrent bladder irritation, the possibility of bladder foreign body should be considered. Surgery is an effective method. For patients without serious complications, cystoscopy is the gold standard for diagnosis and treatment.

RESUMEN

Epigenetics, as a discipline that aims to explain the differential expression of phenotypes arising from the same gene sequence and the heritability of epigenetic expression, has received much attention in medicine. Epigenetic mechanisms are constantly being discovered, including DNA methylation, histone modifications, noncoding RNAs and m6A. The immune system mainly achieves an immune response through the differentiation and functional expression of immune cells, in which epigenetic modification will have an important impact. Because of immune infiltration in the tumor microenvironment, immunotherapy has become a research hotspot in tumor therapy. Epigenetics plays an important role in autoimmune diseases and cancers through immunology. An increasing number of drugs targeting epigenetic mechanisms, such as DNA methyltransferase inhibitors, histone deacetylase inhibitors, and drug combinations, are being evaluated in clinical trials for the treatment of various cancers (including leukemia and osteosarcoma) and autoimmune diseases (systemic lupus erythematosus, rheumatoid arthritis, systemic sclerosis). This review summarizes the progress of epigenetic regulation for cancers and autoimmune diseases to date, shedding light on potential therapeutic strategies.

RESUMEN

Objective: To investigate surgical strategies and the corresponding benefits for patients with perihilar cholangiocarcinoma(pCCA). Methods: A total of 81 patients with pCCA who underwent radical excision in the Department of Biliary and Pancreatic Surgery of Sun Yat-Sen Memorial Hospital between January 2014 and December 2021 were retrospectively collected.The cohort consisted of 50 male and 31 female patients,with an age of (62.5±11.5)years(range:26 to 83 years).Seventy-five cases were diagnosed with jaundice,60 of whom received preoperative biliary drainage,while 20 patients received portal vein embolization.Their serum bilirubin level within one week before the operation(M(IQR)) was 44.3 (41.9) μmol/L(range:8.0 to 344.2 μmol/L).Preoperative imaging examinations were performed to evaluate the Bismuth-Corlette type of pCCA,showing 3,6,21,27,and 24 cases of Bismuth-Corlette type Ⅰ,Ⅱ,Ⅲa,Ⅲb,and Ⅳ,respectively.The primary outcome was overall survival (OS),and the secondary outcomes were relapse-free survival (RFS),90-day postoperative morbidity and 90-day postoperative mortality.OS and RFS were estimated using the Kaplan-Meier method and compared by the Log-rank test.Significant prognostic factors were determined using univariate and multivariable Cox proportional hazard regression analyses. Results: In the cohort of 81 pCCA patients,67 cases(82.7%) underwent major hepatectomy while 3 cases received major hepatectomy combined with pancreaticoduodenectomy.Thirty-four patients underwent hepatectomy combined with vascular resection and reconstruction(18 cases of portal vein resection and reconstruction alone;9 cases of hepatic artery resection and reconstruction alone;7 cases of combination of portal vein and hepatic artery resection and reconstruction).Margin negative(R0 excision) were achieved in 53.1%(43/81) of these patients.The operation duration was (627±136)minutes(range:565 to 940 minutes),and the intraoperative blood loss was 400(455)ml(range:200 to 2 800 ml).The 90-day postoperative mortality was 3.7%(3/81).Grade 3-4 postoperative morbidity was 23.4% (19/81) according to the Clavien-Dindo classification of surgical complications.Up to the last follow-up at September 2022,the follow-up time was 34.0(24.2)months (range:0.4 to 103.6 months).Three patients who died within 90 days after surgery were excluded from the survival analysis.The median OS was 36.10 months (95%CI:18.23 to 42.97 months) and the 1-,3-and 5-year OS rates were 85.3%,46.8% and 27.3%,respectively.The median OS of 41 patients with negative margins was 47.83 months(95%CI:36.90 to 58.80 months) and that of 37 patients with positive margins was 20.47 months(95%CI:10.52 to 30.58 months).The median RFS of 70 patients with R0 and R1 resection was 24.50 months(95%CI:12.15 to 31.85 months)and the 1-,3-and 5-year RFS rates were 65.2%,45.7% and 29.9%,respectively.The median RFS of 41 patients with R0 resection was 38.57 months(95%CI:21.50 to 55.63 months) and that of 29 patients with R1 resection was 10.83 months(95%CI:2.82 to 19.86 months). Conclusions: The primary therapy for pCCA is radical surgical resection.A precise preoperative evaluation and sufficient preparation can reduce postoperative morbidity.Surgical treatment can achieve a better survival outcome by increasing the radical resection rate.

RESUMEN

Objective: To explore the feasibility and application value of intraoperative direct immunohistochemical (IHC) staining in improving the diagnosis accuracy in difficult cases of bronchiolar adenoma (BA). Methods: Nineteen cases with single or multiple pulmonary ground-glass nodules or solid nodules indicated by imaging in Cancer Hospital of Chinese Academy of Medical Sciences from January to July 2021 and with difficulty in differential diagnosis at frozen HE sections were selected. In the experimental group, direct IHC staining of cytokeratin 5/6 (CK5/6) and p63 was performed on frozen sections to assist the differentiation of BA from in situ/micro-invasive adenocarcinoma/adenocarcinoma/invasive mucinous adenocarcinoma. In the control group, two pathologists performed routine frozen HE section diagnosis on these 19 cases. The diagnostic results of paraffin sections were used as the gold standard. The sensitivity and specificity of BA diagnosis, consistency with paraffin diagnosis and time used for frozen diagnosis were compared between the experimental group and the control group. Results: The basal cells of BA were highlighted by CK5/6 and p63 staining. There were no basal cells in the in situ/microinvasive adenocarcinoma/adenocarcinoma/invasive mucinous adenocarcinoma. In the experimental group, the sensitivity and specificity with aid of direct IHC staining for BA were 100% and 86.7%, respectively, and the Kappa value of frozen and paraffin diagnosis was 0.732, and these were significantly higher than those in the control group (P<0.05). The average time consumption in the experimental group (32.4 min) was only 7 min longer than that in the control group (25.4 min). Conclusions: Direct IHC staining can improve the accuracy of BA diagnosis intraoperatively and reduce the risk of misdiagnosis, but require significantly longer time. Thus frozen direct IHC staining should be restricted to cases with difficulty in differentiating benign from malignant diseases, especially when the surgical modalities differ based on the frozen diagnosis.

RESUMEN

Brain delivery of drugs remains challenging due to the presence of the blood-brain barrier (BBB). With advances in nanotechnology and biotechnology, new possibilities for brain-targeted drug delivery have emerged. Biomimetic nano drug delivery systems with high brain-targeting and BBB-penetrating capabilities, along with good biocompatibility and safety, can enable 'invisible' drug delivery. In this review, five different types of biomimetic strategies are presented and their research progress in central nervous system disorders is reviewed. Finally, the challenges and future prospects for biomimetic nano drug delivery systems in intracerebral drug delivery are summarized.

RESUMEN

As a natural product with a long history of medicinal use, parthenolide has aroused great interest of chemists and biologists. Existing studies have shown that it has anti-inflammatory, antitumor and other pharmacological activities, and also revealed its action on NF-κB signaling pathway, DNMT1 enzyme and Wnt/β-catenin signaling pathway. But its biological targets remain to be elucidated systematically. Proteolysis Targeting Chimeras (PROTAC) provides a new strategy for target discovery of natural products, which can be used to explore the panorama of protein changes in cells through proteomic investigation, so as to analyze their potential targets. Based on this idea, current study designed and synthesized 20 parthenolide-derived degraders. After measured their antitumor activity in vitro, selected compounds were carried out the proteomic experiment. Finally, 139 down-regulated differentially expressed proteins were identified and the discovery of parthenolide interacting protein was preliminarily explored.

RESUMEN

ObjectiveTo explore the effect of core stability training on dynamic balance and surface electromyography (sEMG) after anterior cruciate ligament reconstruction (ACLR), and to analyze the correlation between balance index and sEMG. MethodsFrom March to December, 2022, 32 patients with ACLR in Yantai Affiliated Hospital of Binzhou Medical University were randomly divided into control group (n = 16) and experimental group (n = 16). The control group accepted routine rehabilitation treatment, and the experimental group added core stability training, for six weeks. They were evaluated with American Hospital for Special Surgery Knee Score (HSS) and International Knee Documentation Committee Knee Score (IKDC), and the dynamic balance function and sEMG were measured before and after treatment, and the correlation between dynamic balance index and root mean square (RMS) of sEMG was analyzed. ResultsAfter treatment, the scores of HSS and IKDC increased significantly in both groups (|Z| > 3.526, |t| > 63.544, P < 0.001), and were better in the experimental group than in the control group (Z = -2.392, t = 2.650, P < 0.05); the length of gait line and single support line increased significantly, the medial-lateral displacement displacement decreased (|t| > 2.368, Z = -3.516, P < 0.05), and they were better in the experimental group than in the control group (|t| > 2.497, Z = -3.091, P < 0.05); the RMS of gluteus maximus and gluteus medius increased in the experimental group (t = -5.900, Z = -2.741, P < 0.01), and were better than those in the control group (t = 3.930, Z = -3.260, P < 0.01). After treatment, the RMS of gluteus maximus and gluteus medius in both groups were positively correlated with gait line length and single support line length, and were negatively correlated with medial-lateral displacement (|r| > 0.502, P < 0.01). ConclusionCore stability training could significantly improve knee joint function and dynamic balance, and enhance the activation of gluteus maximus and gluteus medius. Dynamic balance is highly correlated with sEMG.

RESUMEN

Objective A program-controlled flexible multi-point temperature measurement device was self developed for collection and analysis of skin temperature signals of diabetic patients and healthy subjects under resting and heating conditions so as to assess vasodilation function of the microcirculation, Methods With reference to the endothelial regulation spectrum of human body, wavelet analysis was performed on skin temperature signals, and the temperature fluctuation amplitudes in diabetic group and healthy control group were compared at different time periods after thermal stimulation. Results The temperature fluctuation amplitude in endothelial spectrum of diabetic group was smaller than that of healthy control group, and the decrease in skin temperature fluctuation after the power-off of thermal stimulation was remarkably smaller than that of control group, indicating that the response to thermal stimulation for diabetic patients was slower. Conclusions Vasodilation function can be quantitatively evaluated by using the fluctuation of skin temperature signals in endothelial spectrum band. Skin temperature monitoring is a potentially easy-implemented method for the health management and early diagnosis of microvascular diseases in diabetic patients.

RESUMEN

AIM: To analyze the effects of aromatase inhibitors(AIs)on the ocular surface microenvironment of the users.METHODS: A cross-sectional observational study was conducted. The study included postmenopausal women who received AIs treatment at galactophore department of our hospital from November 2022 to May 2023. Participants were divided into two groups based on the mechanism of AIs: the steroidal group and the non-steroidal group. The control group consisted of age-matched women who underwent occupational health examinations. All participants completed the ocular surface disease index(OSDI)questionnaire and underwent detailed ophthalmic examinations, including best-corrected visual acuity, intraocular pressure, axial length, corneal curvature, radius of curvature of curved lacrimal river surface, tear osmolarity, tear film break-up time, corneal fluorescein staining score, Schirmer Ⅰ test, and meibomian gland infrared score.RESULTS: There were no statistically significant differences in age, best-corrected visual acuity, intraocular pressure, axial length, and corneal curvature between control group and steroidal and non-steroidal group(P&#x003E;0.05). The duration of drug treatment between the steroidal group and the non-steroidal group also showed no statistically significant difference(P&#x003E;0.05). However, statistically significant differences were observed between the control group and the steroidal and non-steroidal group in OSDI scores, radius of curvature of curved lacrimal river surface, tear osmolarity, tear film break-up time, corneal fluorescein staining score, Schirmer Ⅰ test, and meibomian gland infrared score(P&#x003C;0.05). The Schirmer Ⅰ test also showed statistically significant differences between the steroidal group and the non-steroidal group(P&#x003C;0.05), while other data showed no statistically significant differences(P&#x003E;0.05).CONCLUSION: Postmenopausal patients receiving AIs treatment experienced significant changes in the ocular microenvironment, with both decreased tear secretion and excessive tear evaporation contributing to the occurrence of dry eye. Notably, patients receiving non-steroidal AIs treatment showed a more significant reduction in main lacrimal gland secretion.

RESUMEN

BackgroundInternet-based cognitive behavioral therapy (ICBT) is progressively emerging as an efficacious alternative to alleviate anxiety and depression in cancer patients. To date, no Meta-analysis has been conducted specific to the effect of ICBT on anxiety, depression, distress and quality of life in cancer patients. ObjectiveTo assess the effect of ICBT on distress, depression, anxiety and quality of life in cancer patients through a systematic review of the literature. MethodsOn March 28, 2022, PubMed, PsycINFO, Embase, Cochrane Library, Web of Science, CNKI, VIP, Wanfang Data and CBM were retrieved for the randomized controlled trials (RCTs) involving ICBT targeting either distress, depression, anxiety, quality of life or all in cancer patients. After the risk of bias assessment, Stata 17.0 software was used for Meta-analysis. ResultsA total of 12 RCTs with a total sample size of 1 686 patients were included. Meta-analysis revealed that the superiority of ICBT over controls was evident for interventions targeting distress in cancer patients (SMD=-0.547, 95% CI: -1.090~-0.145, P<0.01), while appeared to be less evident for the interventions targeting depression (SMD=-0.652, 95% CI: -1.734~0.002, P=0.051), anxiety (SMD=-1.045, 95% CI: -3.656~0.101, P=0.088) and quality of life (SMD=0.234, 95% CI: -0.064~0.449, P=0.112) in cancer patients,and dropout rate was higher in ICBT group than that in control group (OR=1.795, 95% CI:1.358~2.374, P<0.01). ConclusionICBT is reported to be effective in alleviating distress in cancer patients, whereas results inconsiderable improvements over depression, anxiety and quality of life in cancer patients.

RESUMEN

OBJECTIVES@#At present, there are many reports about the treatment of cricopharyngeal achalasia by injecting botulinum toxin type A (BTX-A) into cricopharyngeal muscle guided by ultrasound, electromyography or CT in China, but there is no report about injecting BTX-A into cricopharyngeal muscle guided by endoscope. This study aims to evaluate the efficacy of endoscopic BTX-A injection combined with balloon dilatation in the treatment of cricopharyngeal achalasia after brainstem stroke, and to provide a better method for the treatment of dysphagia after brainstem stroke.@*METHODS@#From June to December 2022, 30 patients with cricopharyngeal achalasia due to brainstem stroke were selected from the Department of Rehabilitation Medicine, the First Hospital of Changsha. They were randomly assigned into a control group and a combined group, 15 patients in each group. Patients in both groups were treated with routine rehabilitation therapy, while patients in the control group were treated with balloon dilatation, and patients in the combined group were treated with balloon dilatation and BTX-A injection. Before treatment and after 2 weeks of treatment, the patients were examined by video fluoroscopic swallowing study, Penetration-aspiration Scale (PAS), Dysphagia Outcome Severity Scale (DOSS), and Functional Oral Intake Scale (FOIS) were used to assess the swallowing function.@*RESULTS@#In the combined group, 1 patient withdrew from the treatment because of personal reasons. Two weeks after treatment, the scores of DOSS, PAS, and FOIS in both groups were better than those before treatment (all P<0.01), and the combined group was better than the control group (all P<0.001). The effective rate was 85.7% in the combined group and 66.7% in the control group, with no significant difference between the 2 groups (P>0.05).@*CONCLUSIONS@#BTX-A injection combined with balloon dilatation is more effective than balloon dilatation alone in improving swallowing function and is worthy of clinical application.

RESUMEN

BACKGROUND@#The benefits of healthy lifestyles are well recognized. However, the extent to which improving unhealthy lifestyles reduces cardiovascular disease (CVD) risk needs to be discussed. We evaluated the impact of lifestyle improvement on CVD incidence using data from the China-PAR project (Prediction for Atherosclerotic Cardiovascular Disease Risk in China).@*METHODS@#A total of 12,588 participants free of CVD were followed up for three visits after the baseline examination. Changes in four lifestyle factors (LFs) (smoking, diet, physical activity, and alcohol consumption) were assessed through questionnaires from the baseline to the first follow-up visit. Cox proportional hazard models were used to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs). The risk advancement periods (RAPs: the age difference between exposed and unexposed participants reaching the same incident CVD risk) and population-attributable risk percentage (PAR%) were also calculated.@*RESULTS@#A total of 909 incident CVD cases occurred over a median follow-up of 11.14 years. Compared with maintaining 0-1 healthy LFs, maintaining 3-4 healthy LFs was associated with a 40% risk reduction of incident CVD (HR = 0.60, 95% CI: 0.45-0.79) and delayed CVD risk by 6.31 years (RAP: -6.31 [-9.92, -2.70] years). The PAR% of maintaining 3-4 unhealthy LFs was 22.0% compared to maintaining 0-1 unhealthy LFs. Besides, compared with maintaining two healthy LFs, improving healthy LFs from 2 to 3-4 was associated with a 23% lower risk of CVD (HR = 0.77, 95% CI: 0.60-0.98).@*CONCLUSIONS@#Long-term sustenance of healthy lifestyles or improving unhealthy lifestyles can reduce and delay CVD risk.

Objective:To observe the effects of sparrow-pecking moxibustion at Shenque(CV8)and Guanyuan(CV4)on the writhing reaction and score,the temperature and blood flow perfusion of moxibustion point area and uterus,the serum levels of arginine vasopressin(AVP),prostaglandin(PG)F2α,and thromboxane(TX)B2 in rats with primary dysmenorrhea(PD)due to cold-dampness stagnation,and to explore the possible mechanism of sparrow-pecking moxibustion in treating PD.Methods:Thirty-two healthy non-pregnant female Wistar rats were randomly divided into a normal group,a model group,an ibuprofen group,and a sparrow-pecking moxibustion group,with 8 rats in each group.Except for the normal group,the other three groups were subjected to modeling with cold water bath combined with estradiol benzoate and oxytocin injection.Rats in the sparrow-pecking moxibustion group were treated with sparrow-pecking moxibustion at Shenque(CV8)and Guanyuan(CV4)on the 8th day of modeling,30 min/time,once a day for 3 d;those in the ibuprofen group were treated with 0.8 mL ibuprofen solution(a specification of 125 mg in 10 mL)on the 8th day of modeling,once a day for 3 d;those in the normal group and the model group were given 0.8 mL normal saline,once a day for 3 d.On the 11th day,rats in each group were intraperitoneally injected with oxytocin(2 U/rat),and the writhing incubation period and writhing score in 20 min were observed;the temperature and the blood perfusion of Shenque(CV8),Guanyuan(CV4),and uterus in vivo were detected;the serum levels of AVP,PGF2α,and TXB2 were determined.Results:The writhing incubation period was significantly longer(P<0.01)and the writhing score was significantly lower(P<0.01)in the sparrow-pecking moxibustion group and the ibuprofen group than in the model group;compared with the ibuprofen group,the writhing incubation period was prolonged(P<0.01)and the writhing score was decreased(P<0.01)in the sparrow-pecking moxibustion group;compared with the normal group,the temperature and the blood perfusion of Shenque(CV8),Guanyuan(CV4),and uterus were significantly decreased,while the serum PGF2α,AVP,and TXB2 levels were significantly increased(P<0.01)in the model group;compared with the model group,the temperature and the blood perfusion of Shenque(CV8),Guanyuan(CV4),and uterus were significantly increased,and the serum levels of PGF2α,AVP,and TXB2 were significantly decreased in the ibuprofen group and the sparrow-pecking moxibustion group(P<0.05 or P<0.01);compared with the ibuprofen group,the temperature and the blood perfusion of Shenque(CV8),Guanyuan(CV4),and uterus were significantly increased(P<0.05),the serum AVP and TXB2 levels were significantly decreased(P<0.05),while the serum PGF2α level had no statistical difference in the sparrow-pecking moxibustion group(P>0.05).Conclusion:Sparrow-pecking moxibustion had a remarkable analgesic effect on the rats with PD due to cold-dampness stagnation,and the mechanism may be related to the increased temperature and blood perfusion of the moxibustion point area and uterus,as well as the decreased serum PGF2α,AVP,and TXB2 levels.

RESUMEN

Objective:To investigate the treatment of preterm and low birth weight infants with congenital diaphragmatic hernia (CDH) and to share the experience.Methods:This retrospective study enrolled 117 newborns with CDH who underwent major surgery at Children's Hospital, Capital Institute of Pediatrics from May 1, 2011, to March 31, 2022. Based on gestational age and birth weight, the infants were divided into the preterm and/or low birth weight group (gestational age < 37 weeks and/or birth weight less than 2 500 g, n=41) and the control group (gestational age ≥ 37 weeks and birth weight ≥ 2 500 g, n=76). Furthermore, the preterm and/or low birth weight infants were divided into the thoracoscopic surgery subgroup ( n=31) and the open surgery subgroup ( n=10) according to the surgical approach. Statistical analysis of the data was performed using two independent sample t-tests, rank sum tests, Chi-square test, or Fisher's exact probability test. Results:Preoperative data showed that the Apgar scores at 1 min [7.0 (6.0-8.0) vs 9.0 (8.0-9.8), Z=-4.03] and 5 min [9.0 (8.0-10.0) vs 9.0 (9.0-10.0), Z=-2.13] of the preterm and/or low birth weight infants were both lower than those in the control group (both P<0.05), while the proportion of infants with moderate to severe pulmonary hypertension was higher [68.3% (28/41) vs 38.2% (29/76), χ 2=9.68, P<0.05]. There were no statistically significant differences between the two groups in terms of the proportion of thoracoscopic surgery, operation time, right diaphragmatic hernia, presence of hernia sac, grading of the defect, presence of liver herniation, and application of mesh (all P>0.05). Regarding the postoperative outcomes, the death rate in the preterm and/or low birth weiht group was higher compared to the control group [36.6% (15/41) vs 13.2% (10/76), χ 2=8.70, P<0.05]. Additionally, the time required to resume full enteral nutrition after surgery was longer in the preterm and/or low birth weight group than that in the control group [25 d (18-29 d) vs 16 d (10-25 d), Z=2.31, P<0.05]. The thoracoscopic subgroup had a lower mortality compared to the open surgery subgroup [25.8% (8/31) vs 7/10, P<0.05]. The thoracoscopic surgery subgroup had a higher Apgar score at 1 min after birth [(7.4±1.6) vs (6.0±2.2), t=2.20, P<0.05], later age at operation (hours after birth) [31.0 h (23.0-48.0 h) vs 17.0 h (4.7-24.5 h), Z=2.57, P<0.05], a lower proportion of infants operated within 24 hours after birth [32.3% (10/31) vs 8/10, P<0.05], and longer duration of operation [170.0 min (122.0-200.0 min) vs 110.0 min (87.3-120.0 min), Z=3.65, P<0.05]. Conclusions:In this study, a higher mortality in the preterm and/or low birth weight group compared to the control group was observed, which may be attributed to the higher proportion of neonates with moderate-severe pulmonary hypertension. The thoracoscopic diaphragmatic repair can be attempted for preterm and low birth weight infants who have relatively stable respiratory and circulatory functions.

RESUMEN

Objective:To evaluate the necessity, safety and efficacy of endovascular treatment for cerebral infarction caused by middle cerebral artery (MCA) stenosis with hypoperfusion in the blood supply area of the lenticulostriate artery.Methods:The clinical and surgical data of patients with MCA atherosclerotic disease who underwent endovascular treatment in the First Affiliated Hospital of Zhengzhou University from January 2014 to October 2021 were retrospectively analyzed. A total of 6 patients with cerebral infarction caused by MCA stenosis with hypoperfusion in the blood supply area of the lenticulostriate artery were selected. The preoperative and postoperative clinical imaging characteristics, perioperative complications and follow-up of these 6 patients were summarized and evaluated.Results:After the endovascular treatment, the imaging of the lenticulostriate artery in all the 6 patients was clearer than that before the operation, and the number of main trunks of the lenticulostriate artery shown by imaging in 2 patients was more than that before operation. The computer tomography perfusion of 6 patients after the endovascular treatment showed that perfusion in the supply area of the lenticulostriate artery was significantly improved compared with pre-operation. No stroke, transient ischemic attack (TIA) and death occurred during the perioperative period. The time of clinical follow-up was 360 (322, 495) days, and there were no stroke, TIA or death occurring in the corresponding artery. All the 6 patients underwent imaging follow-up, of which 3 patients underwent digital subtraction angiography and 3 underwent CT angiography. The lumen of the target vessels showed patency in all patients.Conclusions:With rigorous imaging evaluation, endovascular treatment may be safe and effective for cerebral infarction caused by MCA stenosis with hypoperfusion in the blood supply area of the lenticulostriate artery.

RESUMEN

Cellular senescence is a state in which cells enter permanent cell cycle arrest, which is characterized by senescence-associated secretory phenotype secretion, macromolecular damage, metabolic dysregulation and so on. Recent studies have shown a close relationship between cellular senescence and type 2 diabetes. On the one hand, the glycolipotoxic microenvironment of type 2 diabetes can accelerate cell senescence and accumulation. On the other hand, cellular senescence can promote the development of type 2 diabetes. For example, senescence of pancreatic β-cells leads to β-cell dysfunction and adipocytes senescence results in the secretion of pro-inflammatory cytokines, causing disturbances in lipid metabolism and exacerbating insulin resistance. Moreover, senescence of endothelial cells, retinal endothelial cells, and other cell types contributes to the occurrence of chronic complications in diabetes. Cellular senescence is not only an important factor in the onset of type 2 diabetes but also a consequence of its progression. Targeting cellular senescence holds promise as a new strategy for the treatment of type 2 diabetes.
