Objective To compare the short-term outcomes and postoperative complications of endoscopic submucosal dissection(ESD)and endoscopic mucosal resection(EMR)in the treatment of early colorectal cancer.Methods A total of 110 patients with early colorectal cancer who were admitted to Suining Central Hospital from June 2020 to June 2022 were prospectively enrolled and randomly assigned to two groups by random number table.Of them,58 patients underwent ESD and 52 patients underwent EMR.Operation related indexes,inflammatory factors(interleukin-6[IL-6],tumor necrosis factor-α[TNF-α],and C-reactive protein[CRP])before operation and 3 days after operation,and postoperative quality of life index(QL-Index)were compared between the two groups.The complications of the two groups were observed.Results The operation time,hospital stay,postoperative exhaust time,defecation time,and intraoperative blood loss in ESD group were lower than those in EMR group,and the rates of complete resection and en bloc resection in ESD group were higher than those in EMR group(P<0.05).The levels of IL-6,TNF-α and CRP were increased 3 d after operation in both groups,but the levels of IL-6,TNF-α and CRP in ESD group were lower than those in EMR group(P<0.05).The total score of QL-Index and the scores of activity,daily activities,health,and overall situation in ESD group were significantly higher than those in EMR group(P<0.05).The incidence of complications in ESD group was higher than that in EMR group,without significant difference(P>0.05).Conclusion The pocket ESD can effectively promote postoperative rehabilitation,increase resection rate,reduce postoperative inflammation,and improve the quality of life of patients with early colorectal cancer,and there is no obvious complication.

ObjectiveTo evaluate the efficacy and safety of transcutaneous electrical acupoint stimulation (TEAS) for muscle atrophy in patients with immobilization after surgical fixation of foot and ankle fractures.MethodsThis was a two-arm randomized controlled trial wherein 80 patients were recruited and divided into control (n = 40) and intervention (n = 40) groups. The control group received conventional orthopedic treatment, whereas the intervention group received TEAS and conventional treatment. The intervention group received TEAS 3 times a week for 30 min each time for 8 weeks. The primary outcomes were muscle thickness (MT) and cross-sectional area (CSA) of the rectus femoris and gastrocnemius muscles, whereas the secondary outcome measure was echo intensity (EI). Data were collected before the fixation operations (baseline assessment) and 4 and 8 weeks after intervention.ResultsCompared with baseline, the MT and CSA were reduced in both groups by the end of treatment, whereas EI increased in both groups. At week 4, the reduction in the rectus femoris CSA in the intervention group was significantly lower than that in the control group (P = .02); however, the between-group differences in the MT and EI (all P .05) were not significant. No serious adverse events were observed in either group.ConclusionOur study showed that TEAS can improve muscle atrophy by attenuating the decline in the muscle CSA. Because this was only a pilot trial, subsequent studies will need longer follow-ups and larger sample sizes.

Objective: To systematically evaluate the incidence and influencing factors of depression in family caregivers of Alzheimer's disease (AD) patients, so as to provide the basis for the prevention and treatment of depression among the family caregivers of AD patients. Methods: Publications pertaining to depression in family caregivers of AD patients were retrieved from CNKI, Wanfang Data, PubMed and other databases from the time of their establishment to June 15, 2023. The evaluation criteria recommended by the Agency for Healthcare Research and Quality (AHRQ) and the Newcastle-Ottawa Scale were used to assess the quality of cross-sectional and cohort studies, respectively. Stata 16.0 and Revman 5.4 softwares were used to conduct a meta-analysis on the incidence and influencing factors of depression in family caregivers of AD patients. Sensitivity analysis and publication bias assessment were also performed on the results. Results: A total of 2 324 articles were retrieved, and ultimately 14 articles were included, with a total sample size of 8 313 individuals. There were 6 high-quality articles and 8 moderate-quality articles. Meta-analysis showed that the incidence of depression in family caregivers of AD patients was 37.5% (95%CI: 30.2%-45.1%). Factors associated with depression included patients' high degree of dementia (OR=1.718, 95%CI: 1.059-2.789), patients' low scores on Activities of Daily Living Scale (OR=1.344, 95%CI: 1.059-1.706), patients' psychobehavioral abnormalities (OR=1.248, 95%CI: 1.155-1.348), long duration of caregiving (OR=1.998, 95%CI: 1.637-2.437), less involvement of other family members in caregiving (OR=1.597, 95%CI: 1.237-2.061), low educational level (OR=1.191, 95%CI: 1.044-1.359), poor caregiving skills (OR=3.060, 95%CI: 2.257-4.149), poor self-rated health (OR=2.536, 95%CI: 1.114-5.771) and social support (OR=0.424, 95%CI: 0.232-0.774). The results of depression incidence demonstrated good stability with no significant publication bias. However, publication bias was observed in the influencing factors for depression, which were patients' high degree of dementia and patients' low scores on Activities of Daily Living Scale. Conclusions The incidence of depression in family caregivers of AD patients ranges from 30.2% to 45.1%. It is primarily influenced by the severity of patients' symptoms and ability to perform daily activities, and caregivers' educational level, caregiving skills, health status, caregiving duration and social support.

Objective To investigate the effects of β-sitosterol on the proliferation and apoptosis of colon cancer cell HCT116,and its regulation of on phosphoinositide 3-kinase/protein kinase B(PI3K/Akt)signaling pathway.Methods Cultivated colon cancer cells HCT116 in vitro and divided them into β-sitosterol High(240μmol/L)、medium(120μmol/L)and low-dose(60μmol/L)groups,set control group(0μmol/L).Applied different concentrations of β-sitosterol treatment of HCT116 cells.And 24h later,the cell proliferation and activity were determined by cell counting kit-8(CCK-8)method,the morphological changes observed under a microscope;Cell apoptosis was observed by Hoechst 33342 nuclear staining;Used cell colony formation assy to detect the colony forming ability of HCT116 cells;and Western blot was used to evaluate the expression of PI3K,p-Akt,Akt,Bcl-2 and Bax in cells.Used AutoDock software for molecular docking of β-sitosterol with Akt and PI3K.Results Compared with the control group,β-sitosterol could inhibit the proliferation of colon cancer HCT116 cells in a concentration dependent manner,inhibit their colony forming ability and promote cell apoptosis and inhibit the expression of p-Akt、PI3K、and Bcl-2 proteins in HCT116 cells and promotes the expression of Bax protein.The binding of β-sitosterol with PI3K and Akt proteins is relatively stable.Conclusion β-sitosterol may regulate the proliferation and apoptosis of HCT116 through inhibiting PI3K/Akt signaling pathway.

The nucleus accumbens (NAc) plays an important role in various emotional and motivational behaviors that rely on heightened wakefulness. However, the neural mechanisms underlying the relationship between arousal and emotion regulation in NAc remain unclear. Here, we investigated the roles of a specific subset of inhibitory corticotropin-releasing hormone neurons in the NAc (NAc^CRH) in regulating arousal and emotional behaviors in mice. We found an increased activity of NAc^CRH neurons during wakefulness and rewarding stimulation. Activation of NAc^CRH neurons converts NREM or REM sleep to wakefulness, while inhibition of these neurons attenuates wakefulness. Remarkably, activation of NAc^CRH neurons induces a place preference response (PPR) and decreased basal anxiety level, whereas their inactivation induces a place aversion response and anxious state. NAc^CRH neurons are identified as the major NAc projection neurons to the bed nucleus of the stria terminalis (BNST). Furthermore, activation of the NAc^CRH-BNST pathway similarly induced wakefulness and positive emotional behaviors. Taken together, we identified a basal forebrain CRH pathway that promotes the arousal associated with positive affective states.

【Objective】 To investigate the value of three hemolysis tests and carboxyhemoglobin (COHb) level in the diagnosis of hemolytic disease of the fetus and newborn (HDFN). 【Methods】 From January 1, 2019 to December 31, 2022, the neonates hospitalized in the Department of Neonatology of Hebei Provincial Children's Hospital with suspected hemolytic disease who had serological testing were retrospectively enrolled in the study. They were distributed into HDFN group and non-HDFN group according to the final diagnosis. Their clinical and laboratory data were collected and analyzed, and the COHb level was detected by blood gas analyzer. 【Results】 A total of 378 neonates with HDFN and 217 neonates without HDFN were included in the study. Most of the neonates in HDFN group were full-term infants (348/378, 92.1%), with median gestational age of 39.1 (38.3, 40.0) weeks. Three hundred and fifty-four cases (354/378, 93.7%) were ABO-HDFN and the rest were Rh HDFN. There were significant differences in the level of serum total bilirubin, hemoglobin, COHb and reticulocyte percentage at admission between the two groups(P<0.05). The positive rate of three hemolysis tests in HDFN group decreased with the increase of the days after birth. The highest positive rate (more than 80%) was observed within 2 days after birth. Correlation analysis showed a negative relationship between the COHb level and the age (rs = -0.434, P<0.001) . Among the three hemolysis tests in HDFN group, the positive rate of antibody release test was the highest (69.0%), followed by the free antibody test (55.6%) and the direct antiglobulin test (DAT) (36.0%). Receiver operating characteristic (ROC) curve analysis showed that the optimal cut-off value of COHb was 1.15%.The sensitivity of COHb ≥ 1.15% was 51.8%, higher than single DAT (36.0%) . The diagnosis effectiveness of three hemolysis tests couldn't be improved when combined with COHb detection(Z = -0.727, P>0.05) . 【Conclusion】 The three hemolysis tests are important in the diagnosis of HDFN, among which the antibody release test has the highest sensitivity. COHb has certain value for the diagnosis of HDFN, but joint testing cannot improve the diagnosis effectiveness of three hemolysis tests. Hemolysis tests and/or COHb detection should be conducted for neonates at risk of hemolysis as early as possible after birth.

Enzalutamide (ENZ) is a second-generation androgen receptor (AR) antagonist used for the treatment of castration-resistant prostate cancer (CRPC) and reportedly prolongs survival time within a year of starting therapy. However, CRPC patients can develop ENZ resistance (ENZR), mainly driven by abnormal reactivation of AR signaling, involving increased expression of the full-length AR (ARfl) or dominantly active androgen receptor splice variant 7 (ARv7) and ARfl/ARv7 heterodimers. There is currently no efficient treatment for ENZR in CRPC. Herein, a small molecule LLU-206 was rationally designed based on the ENZ structure and exhibited potent inhibition of both ARfl and constitutively active ARv7 to inhibit PCa proliferation and suppress ENZR in CRPC. Mechanically, LLU-206 promoted ARfl/ARv7 protein degradation and decreased ARfl/ARv7 heterodimers through mouse double minute 2-mediated ubiquitination. Finally, LLU-206 exhibited favorable pharmacokinetic properties with poor permeability across the blood-brain barrier, leading to a lower prevalence of adverse effects, including seizure and neurotoxicity, than ENZ-based therapies. In a nutshell, our findings demonstrated that LLU-206 could effectively inhibit ARfl/ARv7-driven CRPC by dual-targeting of ARfl/ARv7 heterodimers and protein degradation, providing new insights for the design of new-generation AR inhibitors to overcome ARfl/ARv7-driven CRPC.
