A longitudinal study of sexual activity and influencing factors in breast cancer patients during treatment in the Southwest of China: a trajectory analysis model.

PURPOSE: The aim of this study was to describe the longitudinal developmental trajectories and its influencing factors of sexual activity in patients with breast cancer during treatment. METHODS: A prospective longitudinal study was conducted, including 225 newly diagnosed breast cancer patients in A tumor specialty three-class hospital in Southwest China. We measured sexual activity at the time of admission and diagnosis (T0) and one month (T1), three months (T2), six months (T3), and nine months (T4) after diagnosis. A trajectory analysis model (GBTM) was used to explore the changes in sexual activity in breast cancer patients. Multivariate binary logistic regression analysis was used to analyse the factors that affected the classification of sexual activity trajectories. RESULTS: The ratio of sexual activity abruptly declined from 100% at baseline to 39.1% at T1. The percentage of sexual activity was improved, from 51.4% at T2 to 63.1% at T4. The optimal model was a 2-group trajectory of sexual activity in breast cancer patients,36.6% in the "low activity group" and 63.4% in the "high activity group." The multivariate binary logistic regression analysis revealed statistically significant and positive correlations between sexual activity and age (ß = 0.085, OR = 1.089, 95%CI 1.035 ∼ 1.145, P = 0.001),libido(ß = 0.774, OR = 2.168, 95%CI 1.337 ∼ 3.515, P = 0.002), vaginal lubrication(ß = 1.254, OR = 33.503, 95%CI 2.000 ∼ 6.137, P<0.001). CONCLUSIONS: Breast cancer patients exhibited varying levels of sexual activity during treatment; higher age was associated with increased sexual activity, which can contribute to the recovery of sexual function. Therefore, it is crucial to provide appropriate guidance on sexual health for younger patients.

Effect of diquafosol sodium combined with sodium hyaluronate on dry eye after pterygium surgery / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To observe the clinical efficacy of 3% diquafosol sodium eye drops combined with sodium hyaluronate eye drops in the treatment of dry eyes after pterygium surgery with lacrimal insufficiency.METHODS: A total of 64 cases(64 eyes)of pterygium patients with lacrimal insufficiency were treated with pterygium resection combined with limbal stem cell transplantation, and they were given routine anti-inflammatory and infection prevention treatment postoperatively. In terms of postoperative dry eye treatment, all patients were randomly divided into two groups. The observation group was treated with 3% diquafosol sodium eye drops combined with sodium hyaluronate eye drops, and the control group was treated with sodium hyaluronate eye drops. The break-up time of tear film(BUT), fluorescein(FL), Schirmer's Ⅰ test(SⅠt), ocular surface disease index(OSDI)score, central corneal thickness(CCT)changes, adverse reactions and complications were observed and compared between the two groups at different times postoperatively.RESULTS: Both groups of pterygium patients were accompanied with mild to moderate dry eyes with insufficient tear secretion preoperatively. At 2 wk after operation, both groups showed shorter BUT and higher FL score compared with those preoperatively(P&#x003C;0.05). There was no significant difference between the two groups(P&#x003E;0.05). At 4 wk after operation, BUT in the observation group was prolonged, OSDI score was decreased(both P&#x003C;0.05), and FL score in both groups was decreased compared with those at with 2 wk after operation(P&#x003C;0.05). The observation group was better than the control group(P&#x003C;0.05). At the first day after operation, the CCT of the two groups was thicker than that preoperatively(P&#x003C;0.05), and there was no significant difference in SⅠt between the two groups before and after operation(P&#x003E;0.05).CONCLUSION: In the treatment of dry eye after pterygium surgery with lacrimal insufficiency, 3% diquafosol sodium eye drops combined with sodium hyaluronate eye drops can effectively reduce the postoperative dry eye symptoms, and its clinical effect is better than that of sodium hyaluronate eye drops alone.

Contrasting effects of DOM and lisuride on impul-sive decision-making in delay discounting task / 中国药理学与毒理学杂志

OBJECTIVE The 5-HT2A receptor is the major target of classic hallucinogens.Both DOM(2,5-dimethoxy-4-methylamphetamine)and lisuride act at 5-HT2A receptors,and lisuride shares comparable affinity with DOM and acts as a partial agonist at 5-HT2A recep-tors.However,not like DOM,lisuride lacks hallucinogenic properties.Impulsive decision-making refers to the prefer-ence for an immediate small reinforcer(SR)over a delayed large reinforcer(LR).The current study aims to compare the effects of DOM and lisuride on impulsive decision-making and further to investigate the possible receptor mechanisms responsible for the actions of the two drugs.METHODS Impulsive decision-making was evaluated in male Sprague-Dawley rats by the percent-age of choice for the LR in delay discounting task(DDT).Delay to the LR changed in an ascending order(0,4,8,16,and 32 s)across one session.RESULTS DOM(0.3 and 0.5 mg·kg-1)increased impulsive decision-making,and the effects of DOM(0.5 mg·kg-1)was blocked by the 5-HT2A receptor antagonist ketanserin(1.0 mg·kg-1)rather than the 5-HT2C receptor antagonist SB-242084(1.0 mg·kg-1).Contrarily,lisuride(0.1,0.3 and 0.5 mg·kg-1)decreased impulsive decision-making.The effects of lisu-ride(0.3 mg·kg-1)were not antagonized by ketanserin(1.0 mg·kg-1),selective 5-HT1A antagonist WAY-100635(1.0 mg·kg-1)or selective dopamine D4 receptor antagonist L-745870(1.0 mg·kg-1),but were attenuated by the selec-tive dopamine D2/D3 receptor antagonist tiapride(40 mg·kg-1).CONCLUSION DOM and lisuride have contrasting effects on impulsive decision-making via distinct recep-tors.DOM-induced increase of impulsivity is mediated by the 5-HT2A receptor,while lisuride-induced inhibition of impulsivity is regulated by the dopamine D2/D3 receptor.

Comparison of efficacy and safety of TACE and DEB-TACE in treatment of patients with unresectable hepatocellular carcinoma / 中华肝胆外科杂志

Objective:To compare the clinical efficacy and safety of conventional transcatheter arterial chemoembolization (TACE) with drug-eluting bead transcatheter arterial chemoembolization (DEB-TACE) in treatment of patients with unresectable hepatocellular carcinoma.Methods:The data of patients with unresectable hepatocellular carcinoma who underwent hepatic artery chemoembolization at General Hospital of Ningxia Medical University from July 2019 to April 2020 were retrospectively analyzed. Of 282 patients who were enrolled, there were 233 males and 49 females, aged (55.9±10.0) years. The groups were divided into the conventional TACE group ( n=179) and the DEB-TACE group ( n=103) based on the treatments. The efficacy of the two groups was compared according to the modified response evaluation criteria in solid tumors. Postoperative adverse effects and liver function between the two groups were compared. Results:The differences in comparing the preoperative and postoperative liver function indexes between the two groups were not statistically significant. Patients who died and were lost to follow-up at 6 months after surgery were excluded and 240 patients were excluded in the efficacy analysis, with 148 patients in the conventional TACE group and 92 patients in the DEB-TACE group. At 6 months after treatment in the conventional TACE group, there were 64 patients (43.2%) with complete remission, 18 patients (12.2%) with partial remission, 27 patients (18.2%) with stable disease, and 39 patients (26.4%) with disease progression. In the DEB-TACE group, the corresponding figures were 38 patients (41.3%), 17 patients (18.5%), 26 patients (28.3%), and 11 patients (12.0%), respectively. The efficacy of DEB-TACE was better than conventional TACE with statistically significant differences between the 2 groups (χ 2=8.96, P=0.030). The incidence of postoperative embolic syndrome was 53.1% (95/179) in the conventional TACE group, which was significantly higher than the 34.0% (35/103) in the DEB-TACE group (χ 2=7.34, P=0.007). Conclusion:The efficacy and safety of DEB-TACE for unresectable hepatocellular carcinoma were superior to those of the conventional TACE group.

Association between triglyceride glucose index and impairment of renal function in community-dwelling middle-aged and elderly population / 中华全科医师杂志

Objective:To explore the relationship between the triglyceride glucose (TyG) index and impairment of renal function in community-dwelling middle-aged and elderly population.Methods:A total of 4 988 residents aged ≥45 years undergoing health check-up in Yongshun Health Service Center from January 2016 to December 2021 were enrolled and followed up. According to the quartile of the baseline TyG index, all subjects were divided into Q1, Q2, Q3 and Q4 groups. The medical history, physical examination and laboratory test results were documented. Participants were followed up through regular health check-up until March 31, 2023. The outcomes were rapid decline of estimated glomerular filtration rate (eGFR) (a loss in eGFR>3 ml·min -1·1.73 m -2 per year) and the new-onset of chronic kidney disease (CKD) during the follow-up period. Linear regression model, multivariate logistic regression model, restricted cubic spline fitting logistic regression model and ROC curve analysis were used to analyze the association between the TyG index and the impairment of renal function. Results:Among 4 988 residents, 1 396 (28.0%) were males and the age was (59.76±6.28) years. There were 1 247 participants in Q1, Q2, Q3 and Q4 groups, respectively. After 56 months of follow-up, the incidence of rapid eGFR decline and new-onset CKD was 21.9% (1 294/4 988) and 4.0% (200/4 988), respectively. Multivariate logistic regression model analysis showed that TyG index was correlated positively with rapid eGFR decline and new-onset of CKD ( OR=1.34, 95%CI: 1.17-1.52, P<0.001, and OR=1.57, 95%CI:1.19-2.06, P=0.001). Taking group Q1 as a reference, higher levels of TyG index ( Q2, Q3 and Q4 groups) was an independent risk factor for rapid eGFR decline ( P<0.05), which has a dose-response relationship (for trend P=0.002). Compared with the lowest quartile, the adjusted OR of new-onset CKD in the highest quartile was 1.85 ( 95%CI:1.13-3.03, P=0.014). The results of restricted cubic spline fitting logistic regression analysis showed a linear association between TyG index and both outcomes (both P>0.05). The area under ROC curve ( AUC) of the TyG index for predicting the two adverse outcomes were 0.536 ( 95%CI: 0.516-0.556, P<0.001) and 0.588 ( 95%CI:0.548-0.627, P<0.001), respectively. Conclusion:The elevated levels of TyG index may be used as an independent predictor of rapid eGFR decline and new-onset CKD.

Efficacy and safety of glucokinase activators for type 2 diabetes mellitus therapy：a meta-analysis / 中国药房

OBJECTIVE To systematically evaluate the efficacy and safety of glucokinase activators in the treatment of type 2 diabetes mellitus. METHODS PubMed， Cochrane Library， Web of Science， Embase and CNKI databases were searched from the inception to March 2022. Randomized controlled trials about glucokinase activators versus placebo （or other oral hypoglycemic agents） in the treatment of type 2 diabetes were included， data were extracted and meta-analysis was analyzed using RevMan 5.4 software. RESULTS A total of 9 studies with 215 0 patients were included. In terms of hypoglycemic effect， compared with control group， glucokinase activators significantly reduced glycosylated hemoglobin （HbA1c） [MD＝－0.40， 95%CI（－0.53， －0.26）， P＜0.000 01]， fasting blood glucose[MD＝－0.53， 95%CI（－0.85， －0.20）， P＝0.001] and 2 h postprandial blood glucose [MD＝－2.28， 95%CI（－2.68， －1.88）， P＜0.000 01] in diabetic patients. In terms of safety， the incidence of hypoglycemia caused by glucokinase activators was higher than control group on the whole [RR＝1.55， 95%CI（1.20，2.01）， P＝ 0.000 8]. According to the subgroup analysis of organs activated by glucokinase activator， the incidence of hypoglycemia in the pancreas-liver dual activator group [RR＝1.44， 95%CI（1.11，1.89）， P＝0.007] and liver-selective activator group [RR＝2.26， 95%CI（1.02，5.03）， P＝0.05] was higher than that in the control group， the difference was statistically significant. CONCLUSIONS Glucokinase activators can effectively reduce HbA1c， fasting blood glucose and 2 h postprandial blood glucose in patients with type 2 diabetes， but the risk of hypoglycemia remains to be addressed.

Pharmacoeconomic evaluation of clopidogrel versus aspirin for secondary prevention of ischemic stroke / 中国药房

OBJECTIVE To evaluate the cost-effectiveness of clopidogrel versus aspirin monotherapy regimens for secondary prevention of ischemic stroke and to provide economic evidence and reference for clinical medication and decision-making. METHODS Based on the CAPRIE trial， a Markov model was constructed； the probabilities of risk events， health utility values， and costs of risk event management were obtained from relevant literature. The cycle length was 6 months， and the time horizon was 10 years. A discount rate of 5% per year was applied. The primary outcomes were total costs， quality-adjusted life-years （QALYs）， and incremental cost-effectiveness ratio （ICER）. Cost-utility analysis was performed for above 2 regimens by using TreeAge Pro software. The one-way sensitivity analysis， probabilistic sensitivity analysis and scenario analysis were conducted to validate the robustness of the analyses. RESULTS Compared with the aspirin regimen （325 mg/d of CAPRIE trial dose）， the ICER values of clopidogrel regimen for secondary stroke prevention for 10 years， 20 years and 30 years were 4 284.06， 4 201.20 and 3 986.78 yuan/QALY， respectively， which were E-mail：liuxiaoyanrj@sjtu.edu.cn all less than the willing-to-pay （WTP） threshold of one time 。 China’s per capita gross domestic product （GDP） in 2021. E-mail：scilwsjtu-wb@yahoo.com Compared with the aspirin regimen （clinically recommended dose in China， 100 mg/d）， the ICER values of clopidogrel regimen for stroke secondary prevention for 10 years， 20 years and 30 years were 58 238.27， 42 164.72 and 36 164.77 yuan/QALY， respectively， which were all less than WTP threshold. When comparing with aspirin regimen of 325 mg/d， results of one-way sensitivity analysis showed that the cost of clopidogrel and aspirin， probability of the first recurrence of ischemic stroke were sensitive factors of model. Results of probabilistic sensitivity analysis showed that when WTP was set at one time GDP per capita in China in 2021， clopidogrel had a probability of being cost- effective of about 66.5%. Results of scenario analysis showed that neither changing the time horizon to 10， 20 or 30 years nor using different doses of aspirin （50， 100， 150， 200 or 250 mg/d） would not alter any conclusions. CONCLUSIONS Compared with aspirin monotherapy， clopidogrel monotherapy is more cost-effective for secondary prevention of ischemic stroke.

Anti-tumor Mechanisms of Bruceine D： A Review / 中国实验方剂学杂志

Malignant tumors seriously threaten human life and health. Radiotherapy and chemotherapy are the conventional methods for the clinical treatment of advanced tumors. The prognosis and efficacy are still far from satisfactory due to the radiotherapy has serious adverse effects on the body and the chemotherapy often causes problems such as tumor resistance and cell proliferationinhibition. Therefore， the search for new， safe， and effective anti-tumor drugs and the elucidation of their molecular mechanisms are effective measures for clinical treatment of tumors and improvement of patients' quality of life. Active ingredients derived from Chinese herbal medicines and natural products have gradually become a hot spot in the research and development of anti-tumor drugs due to their multi-target and multi-channel anti-tumor pharmacological activity characteristics and their advantages such as less adverse reaction on the body. Bruceine D is a class of tetracyclic triterpenoids extracted from the fruit of the Chinese herbal medicine Bruceae Fructus， with anti-inflammatory， anti-malarial， anti-parasitic， and other pharmacological activities， and its anti-tumor activity is particularly significant. Pharmacological studies have found that bruceine D can regulate various cellular physiological activities such as proliferation， apoptosis， invasion， and migration of lung cancer， liver cancer， pancreatic cancer， intestinal cancer， and other cancer cells by targeting different signaling pathways. Bruceine D can be used in combination with other chemotherapeutic drugs to improve the sensitivity of tumor cells to chemotherapeutic drugs， thereby reducing the adverse effect of chemotherapy. Clinical application practice has shown that Bruceae Fructus oil emulsion injection containing bruceine D has significant advantages in the efficacy and safety of tumor treatment. Although there are many studies on the antitumor pharmacological activity of bruceine D and its clinical efficacy is significant， the specific antitumor molecular mechanism of bruceine D is still unclear， and there is a lack of systematic review on the existing antitumor mechanism of bruceine D. Therefore， based on the research on bruceine D in China and abroad in recent years， this paper reviewed the anti-tumor effect and related molecular mechanisms of bruceine D from six aspects， namely， tumor cell proliferation， apoptosis， metastasis and invasion， glucose metabolism process， autophagy， and chemotherapy sensitivity. This paper is expected to provide a pharmacological basis and scientific reference for the antitumor drug development and clinical application of bruceine D.

Predicting Pathological Complete Response in Breast Cancer After Two Cycles of Neoadjuvant Chemotherapy by Tumor Reduction Rate: A Retrospective Case-Control Study / 한국유방암학회지

Purpose@#We aimed to identify effectiveness-associated indicators and evaluate the optimal tumor reduction rate (TRR) after two cycles of neoadjuvant chemotherapy (NAC) in patients with invasive breast cancer. @*Methods@#This retrospective case-control study included patients who underwent at least four cycles of NAC at the Department of Breast Surgery between February 2013 and February 2020. A regression nomogram model for predicting pathological responses was constructed based on potential indicators. @*Results@#A total of 784 patients were included, of whom 170 (21.68%) reported pathological complete response (pCR) after NAC and 614 (78.32%) had residual invasive tumors. The clinical T stage, clinical N stage, molecular subtype, and TRR were identified as independent predictors of pCR. Patients with a TRR > 35% were more likely to achieve pCR (odds ratio, 5.396; 95% confidence interval [CI], 3.299–8.825). The receiver operating characteristic (ROC) curve was plotted using the probability value, and the area under the ROC curve was 0.892 (95% CI, 0.863–0.922). @*Conclusion@#TRR > 35% is predictive of pCR after two cycles of NAC, and an early evaluation model using a nomogram based on five indicators, age, clinical T stage, clinical N stage, molecular subtype, and TRR, is applicable in patients with invasive breast cancer.

Skin lesions manifested as acute urticaria in 25 cases (41.0%), eruptive/maculopapular lesions in 10 cases (16.4%), facial vascular edema in 6 cases (9.8%), urticarial vasculitis in 5 cases (8.2%), pityriasis rosea and erythema multiforme each in 4 cases (6.6%), purpura in 2 cases (3.3%), mixed skin lesions in 2 cases (3.3%), and folliculitis, erythema nodosum, as well as angioedema of the limbs each in 1 case (1.6%). The age of children with different skin manifestations significantly differed ( F = 4.67, P < 0.001). Forty-eight patients (78.69%) presented with generalized skin lesions, while 13 (21.31%) with localized skin lesions; 10 (16.4%) had itching, 3 (4.9%) had a burning sensation, while 48 (78.7%) showed no symptoms. Skin lesions persisted for ≤ 3 days in 36 cases (59.0%) and for > 3 days in 25 cases (41.0%), and all lesions persisted for less than 2 weeks. All 61 patients had fever up to 38.5 ℃; 1 (1.6%) developed skin lesions before the fever, 41 (67.2%) developed lesions during the fever, and 19 (31.2%) developed lesions after the fever. The skin manifestations significantly differed among various groups divided by patients with different lesion distribution, self-reported symptoms, duration of lesions, and sequence between fever and lesion onset (all P < 0.05). No recurrence was observed after recovery, and skin lesions subsided without pigment changes or scaring. Conclusion:COVID-19 was often accompanied by various skin lesions in children, which mainly manifested as urticaria and eruptive/maculopapular lesions.

Liraglutide ameliorates palmitic acid-induced insulin resistance in L6 skeletal muscle cells by regulating Sestrin2 / 中华内分泌代谢杂志

Objective:To investigate the role of stress-inducible protein Sestrin2 (Sesn2) in the improvement of insulin resistance in rat L6 skeletal muscle cells treated with liraglutide.Methods:The establishment of insulin resistance model of rat L6 skeletal muscle cells was induced by palmitate. The experimental cells were divided into control group(Con group), palmitate 0.6 mmol/L treatment group(PA group), palmitate 0.6 mmol/L+ liraglutide 10 nmol/L treatment group(PA+ Lir10 group), palmitate 0.6 mmol/L+ liraglutide 100 nmol/L treatment group(PA+ Lir100 group), and palmitate 0.6 mmol/L+ liraglutide 1 000 nmol/L treatment group(PA+ Lir1000 group). The cell counting kit 8(CCK8) method was used to detect the cell activity in each group. Western blotting was used to detect the expression levels of glucose transporter 4(GLUT4), protein kinase B(Akt), phosphorylated protein kinase B(p-Akt), and Sesn2 protein in L6 cells. L6 cells were transfected with siRNA to inhibit the expression of Sesn2. The cells were treated with palmitate and liraglutide. Western blotting was used to detect the expression levels of Sesn2, Akt, p-Akt, and GLUT4 protein in L6 cells.Results:Compared with Con group, the cell survival rate, p-Akt/Akt ratio, Sesn2, and GLUT4 protein expression in PA group decreased significantly( P<0.05). After liraglutide intervention, the cell activity, p-Akt/Akt ratio, Sesn2, and GLUT4 protein expression of PA+ Lir100 and PA+ Lir1000 groups was increased( P<0.05). After inhibiting the expression of Sesn2, p-Akt/Akt ratio and GLUT4 protein in transfected si-Sesn2 and treated with 0.6 mmol/L palmitate group(PA+ si-Sesn2 group) and transfected si-Sesn2 and treated with 0.6 mmol/L palmitate+ liraglutide 100 nmol/L group (Lir100+ PA+ si-Sesn2 group) were significantly lower than those in transfection negative group (si-Con group; P<0.05). Even after liraglutide intervention, compared with PA+ si-Sesn2 group, p-Akt/Akt ratio and GLUT4 protein expression level were not significantly increased in Lir100+ PA+ si-Sesn2 group ( P>0.05). Conclusions:Palmitate could induce the decrease of p-Akt/Akt ratio and GLUT4 protein expression in L6 cells. Liraglutide upregulates the expression of Sesn2, which leads to the increase of p-Akt/Akt ratio and GLUT4 protein expression and contributes to the improvement of insulin resistance.

Epidemiology, pathogenesis and early identification of coronary artery lesions in Kawasaki disease / 国际儿科学杂志

Coronary artery lesions are the most serious complications of Kawasaki disease.The incidence of Kawasaki disease is still on the rise in recent years, and the proportion of children with coronary artery dilatation increased in parallel with the incidence of Kawasaki disease.But the incidence of severe coronary artery lesions, such as giant coronary aneurysms, coronary artery stenosis and even occlusion is stable or declining.The pathological changes of coronary artery disease are different with the severity and duration of the disease.Early recognition of coronary artery lesions should not be limited to the observation of luminal dimensions, but also should be explored in depth about the changes of coronary artery structure and function.

Advances in Kawasaki disease combined with giant coronary aneurysm / 国际儿科学杂志

Kawasaki disease coronary artery lesions have become one of the common acquired cardiovascular diseases in children in some countries and regions.Giant coronary artery aneurysms are a severe type of Kawasaki disease coronary artery lesion with less likelihood of complete recovery at a later stage, and their cardiovascular event rate and mortality are significantly higher than those of other children with Kawasaki disease.Children with giant coronary aneurysms are at higher risk of cardiovascular disease in adulthood and are closely associated with sudden cardiac death in young adulthood and the development of coronary atherosclerosis in adulthood, with serious implications for the long-term prognosis and quality of life of the child.This article reviews the clinical features and prognosis of Kawasaki disease combined with giant coronary aneurysms.
