Asiaticoside enhances the effect of propofol on the invasion, ferroptosis and immune escape of bladder cancer.

Bladder cancer is a highly prevalent malignancy. Asiaticoside (AC), a triterpenoid derivative, exhibits antitumor effect on different tumors. This study aimed to explore the role and mechanism of AC on bladder cancer. J82 and T24 cells were treated with AC and/or propofol, and nude mice were subcutaneously administrated with T24 cells. The effect and mechanism of AC and/or propofol were explored by cell counting kit-8, transwell, flow cytometry, enzyme-linked immunosorbent assay, immunohistochemistry and western blot assays both in vitro and in vivo. Cell viability of J82 and T24 cells was inhibited by AC with a IC50 value of 2.43 µM and 2.16 µM, and by propofol with a IC50 value of 42.51 µM and 48.37 µM, respectively. AC or propofol alone decreased cell proliferation, invasion, and immune escape with the increased ferroptosis, as well as downregulating the level of the PI3K/AKT pathway in both animal and cell experiments. The effect of propofol on the above-mentioned indicators was further enhanced with the co-treatment of AC in vitro and in vivo. Taken together, AC promoted the ameliorative effect of propofol on bladder cancer involved in PI3K/AKT pathway.

An evaluation of the effectiveness and safety of the Enhanced Recovery After Surgery (ERAS) program for patients undergoing colorectal surgery: a meta-analysis of randomized controlled trials.

Introduction: The Enhanced Recovery After Surgery (ERAS) protocol reduces surgery-related stress and hospital stays for complicated surgical patients. It speeds recovery, reduces readmissions, and lowers morbidity and mortality. However, the efficacy of ERAS in colorectal surgery is still debatable. Aim: To evaluate the effectiveness and safety of the ERAS program for patients undergoing colorectal surgery. Material and methods: PRISMA-compliant searches were performed on Medline, Embase, PubMed, the Web of Sciences, and the Cochrane Database up to March 2023. The included articles compared ERAS protocol results for colorectal surgery patients to those of conventional care. RevMan was used for the meta-analysis, and the Cochrane RoB Tool was used to assess the study quality. Results: The meta-analysis included 12 randomized controlled trials with a total of 1920 participants. There were 880 individuals in ERAS care and 1002 in conventional care. Weighted mean difference: -1.07 days, 95% confidence interval (CI): -1.53 to -0.60, p = 0.00001), overall length of stay: -4.12 days, 95% CI: -5.86 to -2.38, p = 0.00001), and post-operative hospital stay: -1.91 days, 95% CI: -4.73 to -0.91, p = 0.00001). Readmissions were higher in the ERAS group than in the normal care group (odds ratio (OR) = 1.20, 95% CI: 0.82 to 1.75, p = 0.35). Post-operative complications were lower in the ERAS care group (OR = 0.42; 95% CI: 0.27 to 0.65, p < 0.0001) and SSIs (OR = 0.75; 95% CI 0.52 to 1.08, p = 0.00001) than in the routine care group. Conclusions: Care provided in line with the ERAS protocol has been shown to be successful and beneficial for patients following colorectal surgery, because it minimizes post-operative problems and length of hospital stay, and improves outcomes.

Clinical Observation of General Anesthesia Combined with Spinal Anesthesia in Elderly Patients with Chronic Obstructive Pulmonary Disease.

Objective: This work is aimed at evaluating the efficacy and safety of general anesthesia (GA) combined with spinal anesthesia (SA) (GA+SA) in elderly patients with chronic obstructive pulmonary disease (COPD). Methods and Material. 50 elderly COPD patients were rolled randomly into a control group (simple GA) and observation group (GA+SA). The differences in operation time, postoperative recovery time (PRT), language expression time (LET), anesthetic dosage (AD), catheter extubation time (CET), respiratory circulation indicators (mean arterial pressure (MAP), heart rate (HR), SaO2, and PaO2), postoperative VRS score, pulmonary function (forced vital capacity (FVC)), forced expiratory volume in 1 s (FEV1)/FVC and forced expiratory flow (FEF 25%~75%), serum inflammatory factors (IL-6, IL-8, and TNF-α), Short Portable Mental Status Questionnaire (SPMSQ) score, and the incidence of respiratory system events were analyzed. Results: The results showed that the PRT, LET, AD, and CET of the observation group were all shorter (P < 0.05). The postoperative MAP, HR, SaO2, and PaO2 levels of patients who received GA+SA were much higher than those who received simple GA (P < 0.05). The postoperative VRS score of the observation group was better than that of the controls (P < 0.05). The postoperative pulmonary function of patients in the observation group was better compared with that in the control group (P < 0.05). The postoperative serum inflammatory factors in the observation group were lower in contrast to the patients who received simple GA (P < 0.05). The postoperative cognitive function SPMSQ score of patients who received GA+SA was lower compared with the score of patients who received simple GA (P < 0.05). However, the probability of respiratory system events in the observation group was lower (P < 0.05). Conclusion: In conclusion, GA+SA could significantly shorten the PRT and improve the recovery quality of elderly COPD patients. It can also reduce the postoperative inflammatory response and strengthen the pulmonary function and cognitive function. It also enhances the analgesic which is beneficial to patients' postoperative recovery. Therefore, GA+SA was a highly effective and safe anesthesia method for elderly patients with COPD, and it was worthy of clinical application.

Effect of comprehensive rehabilitation nursing intervention on hemiplegia patients in sequela stage of stroke.

OBJECTIVE: To explore the clinical effect of comprehensive rehabilitation nursing intervention on hemiplegia patients in the sequela stage of stroke. METHODS: Patients with knee reflex after stroke were divided into the treatment group and the control group. Patients in the control group received Activities of Daily Living (ADL) training. Patients in the treatment group received comprehensive rehabilitation training in addition to the ADL training of the control group, including joint flexion and extension training, active resistance training, low-frequency electrotherapy, and standing training. The knee reflex angle and ankle dorsiflexion angle of patients in both groups were measured before and after 4 weeks of treatment. Also, the Manual Muscle Testing (MMT) scale, the modified Ashworth scale, the Fugl-Meyer assessment (FMA), and Barthel index (lower limb) rating scale of patients in both groups were compared. RESULTS: It was found that there was significant difference between the two groups in the changes of knee and ankle joint angles after treatment (P < 0.05). In the Ashworth and MMT (Manual Muscle Testing) grading analysis of patients, it was found that the Ashworth grading of quadriceps femoris and triceps leg improved significantly before and after treatment (P < 0.01). There was significant difference in MMT grade between the two groups after treatment of quadriceps and hamstring muscles (P < 0.05). There was significant difference in satisfaction degree of pain control or relief methods (P < 0.05). In the analysis of Fugl-Meyer and Barthel integral effects of lower limbs for the patients with knee reflex before and after treatment, a significant difference (P < 0.05) was found in the Fugl-Meyer motor function and Barthel index scores of the two groups. CONCLUSIONS: Therefore, the results suggested that comprehensive rehabilitation nursing could promote the treatment of sequelae of hemiplegia. Although there were some shortcomings in the experimental process, it still provided a reliable basis for the clinical treatment of sequelae of stroke.

Promoter methylation and expression of Raf kinase inhibitory protein in esophageal squamous cell carcinoma.

Raf kinase inhibitory protein (RKIP) regulates multiple cellular processes, and its downregulation is associated with distinct human cancers. In the present study, the status of RKIP promoter methylation, as well as its expression and clinical significance in esophageal squamous cell carcinoma (ESCC), were examined. The promoter methylation status in the 5'-CpG island of the RKIP gene and the expression level of the RKIP protein were examined using a modified methylation-specific polymerase chain reaction (MSP) method and immunohistochemical staining, respectively, in 77 ESCC samples and matched paratumor normal tissues. The incidence of RKIP promoter methylation was significantly higher in tumor samples (75.3%) than in the matched normal tissues (27.3%; P<0.001). A higher incidence of promoter methylation was also detected in poorly differentiated cancers (93.5%) compared with well-differentiated cancers (50.0%; P<0.001), as well as in tumor samples with positive lymph node metastasis (86.7%) compared with those with negative lymph node metastasis (59.4%; P<0.001). Consistent with the promoter methylation status, the expression level of RKIP was significantly reduced in cancer tissues (36.4%) compared with matched normal tissues (76.6%; P<0.01), as well as in cancers with positive lymph node metastasis (24.4%) compared with those with negative lymph node metastasis (53.1%; P=0.01). Promoter methylation-induced gene silencing significantly correlated with the down regulation of RKIP and the development of ESCC. The results of the present study suggested that the methylation status of the RKIP promoter, when combined with its expression level, may serve as a biomarker for predicting the biological behaviors of ESCC.

Opioids increase hip fracture risk: a meta-analysis.

The relationship between hip fracture risk and opioid use remains controversial. Thus, we performed a meta-analysis to assess the risk of hip fracture among opioid users. PubMed and EMBASE were searched for studies published from the inception of the databases until June 2015. The information was extracted independently by two teams of authors. When the heterogeneity was significant, the random-effects model was used to calculate the overall pooled risk estimates. Ten studies with 697,011 patients were included in the final meta-analysis. The overall combined relative risk for the use of opioids and hip fracture was 1.54 [95 % confidence interval (CI) 1.34-1.77]. Subgroup analyses revealed sources of heterogeneity, and sensitivity analysis indicated stable results, and no publication bias was observed. This meta-analysis demonstrates that opioids significantly increase the risk of hip fracture.

Effect of dimethyl fumarate on rats with chronic pancreatitis.

OBJECTIVE: To discuss the effect of dimethyl fumarate (DMF) on rats with l-arginine induced chronic pancreatitis (CP). METHODS: Male Wistar rats were given DMF treatment (25 mg/kg) by oral lavage method; then Wistar rats were given the intraperitoneal injection of l-arginine for 5 times (250 mg/100 kg, twice per time, each interval of 1 h) for building of CP model. Rats were divided into control group, CP group, DMF group and CP + DMF group. Rats in CP + DMF group were given the oral intragastric administration of DMF (25 mg/kg), while rats in control group and CP group were given the equal volume of normal saline. The weight of rats was evaluated and the intraperitoneal glucose tolerance test was performed (IPGTT, 2 g/kg). The islet of rats was isolated and then flow cytometry was employed to evaluate the quality and activity of islets. Meanwhile, the histology of non-endocrine tissues and levels of myeloperoxidase (MPO) and malondialdehyde (MDA) were detected. RESULTS: Compared with control group, the weight of rats in CP group was significantly reduced at week 2, 4 and 6; the blood glucose significantly increased, AUC increased, the histopathological scores of pancreatic atrophy, acinar injury, edema and cellular infiltration increased, levels of MDA and MPO increased, the islet equivalent and islet activity decreased at 0, 30, 60, 120 and 180 min. Compared with CP group, the weight of rats in CP + DMF group significantly increased at week 2, 4 and 6; the blood glucose significantly decreased, AUC decreased, the histopathological scores of pancreatic atrophy, acinar injury, edema and cellular infiltration decreased, levels of MDA and MPO decreased, the islet equivalent and islet activity increased at 0, 30, 60, 120 and 180 min. CONCLUSIONS: DMF treatment can improve CP induced by l-arginine and islet function in rats.

Expression of RKIP, E-cadherin and NF-kB p65 in esophageal squamous cell carcinoma and their correlations.

To detect the expression of RKIP, E-cadherin and NF-kB p65 in esophageal squamous cell carcinoma (ESCC) and study their correlations. Steptavidin-peroxidase (S-P) method was employed to detect the expressions of RKIP, E-cadherin and NF-kB p65 in ESCC tissues from 77 cases and paracancerous tissues from 77 cases. The correlations between their expressions and clinicopathological indices and between the expressions of these proteins themselves were analyzed. The expressions of RKIP and E-cadherin in ESCC tissues were obviously lower than those in the paracancerous tissues (P<0.01); the expressions in ESCC tissues from cases with lymph node metastasis were lower than those from cases without lymph node metastasis (P<0.01); the expression of RKIP was positively correlated with the expression of E-cadherin in ESCC tissues (P<0.01). The expression of NF-kB p65 in ESCC tissues was correlated with clinical staging, lymph node metastasis and tumor differentiation (P<0.01); the expression of RKIP was negatively correlated with the expression of NF-kB p65 in ESCC tissues (P<0.05). Downregulation or depletion of RKIP was related to the onset and progression of ESCC, and facilitated the invasion and metastasis of ESCC by downregulating E-cadherin and upregulating NF-kB p65.
