BACKGROUND:It has been elucidated that downregulation of nuclear enriched abundant transcript 1(NEAT1)inhibits the progression of keloid fibroblasts,but the exact mechanism is not fully understood. OBJECTIVE:To investigate the influences of long non-coding RNA nuclear enriched abundant transcript 1(lncRNA NEAT1)on the proliferation,apoptosis and migration of keloid fibroblasts by regulating the miR-136-5p/ubiquitin-specific protease 4(USP4)axis. METHODS:Keloid fibroblasts were divided into five groups:si-NC group,control check group,si-NEAT1 group,si-NEAT1+miR-136-5p inhibitor group,and si-NEAT1+inhibitor-NC group.qRT-PCR was performed to measure the expressions of NEAT1 and miR-136-5p;cell counting kit-8 assay and EDU staining were performed to measure cell proliferation;flow cytometry was performed to measure apoptosis;scratch-healing experiment was performed to measure cell migration;western blot assay was performed to measure the protein expressions of USP4,p27,Bax,matrix metalloproteinase-9,α-smooth muscle actin,and type I collagen α1 chain;dual-luciferase assay was performed to examine the relationship of NEAT1 with miR-136-5p as well as the relationship of miR-136-5p with USP4. RESULTS AND CONCLUSION:Compared with the si-NC group,the NEAT1 expression,absorbance value at 450 nm,percentage of EDU positive cells,scratch-healing rate,the protein expressions of USP4,matrix metalloproteinase-9,α-smooth muscle actin,and type I collagen α1 chain decreased in the si-NEAT1 group(P<0.05),while the expression of miR-136-5p,apoptosis rate,and the protein expressions of p27 and Bax increased(P<0.05).miR-136-5p inhibitor reversed the effect of silencing NEAT1 on the biological behavior of keloid fibroblasts.There was a targeted regulatory relationship between NEAT1 and miR-136-5p as well as between miR-136-5p and USP4.To conclude,silencing NEAT1 may inhibit the proliferation and migration of keloid fibroblasts and induce apoptosis by regulating the miR-136-5p/USP4 axis..

Objective:To construct and preliminary evaluate a survival prediction model for immunosuppressant treatment of advanced non-small cell lung cancer (NSCLC) patients with KRAS mutations.Methods:A retrospective cohort study was conducted. Eighty-seven KRAS-mutant advanced NSCLC patients treated with immunosuppressants who were admitted to Shanxi Province Cancer Hospital from May 2017 to May 2020 were selected and followed up until May 2023. Kaplan-Meier overall survival curves were plotted. The patients were categorized into survival and death groups based on survival status at the final follow-up, with 31 and 56 cases in each group respectively, and the clinical data were compared between the two groups. Cox proportional hazards model was used to screen the risk factors affecting the death of patients, and a Cox regression prediction model for the survival of such patients was constructed based on the above risk factors. Using survival status at the final follow-up as the gold standard, receiver operating characteristic (ROC) curves for this predictive model to predict survival in immunosuppressant-treated KRAS-mutant advanced NSCLC patients were plotted.Results:Of the 87 patients, 57 (65.5%) were male and 30 (34.5%) were female, aged (62±8) years. Patients had a median overall survival time of 18.5 months (95% CI: 7.5-37.5 months) and a 3-year cumulative survival rate of 35.63% (31/87). Compared with the survival group, the Eastern Cooperative Oncology Group physical status (ECOG-PS) score, carcinoembryonic antigen (CEA), red blood cell distribution width (RDW), fibrinogen (FIB), D-dimer (D-D), lactate dehydrogenase (LDH), and neutrophil-to-lymphocyte ratio (NLR) in the death group were higher, and the differences were statistically significant (all P < 0.05). Cox regression analysis showed elevated ECOG-PS score ( HR = 1.925, 95% CI: 1.745-2.515, P < 0.001), elevated RDW ( HR = 2.012, 95% CI: 1.820-2.619, P < 0.001), elevated FIB ( HR = 2.060, 95% CI: 1.908-2.678, P = 0.009), elevated D-D ( HR = 2.112, 95% CI: 1.885-2.791, P = 0.012), elevated LDH ( HR = 2.104, 95% CI: 1.901-2.643, P < 0.001), elevated NLR ( HR = 1.998, 95% CI: 1.764-2.580, P < 0.001) were all independent risk factors for death in immunosuppressant-treated advanced NSCLC patients with KRAS mutations. A Cox regression prediction model was constructed based on the above risk factors: prognostic index (PI)=-10.342+0.582×ECOG-PS score+0.605×RDW+0.610×FIB+0.599×D-D+0.612×LDH+0.618×NLR. ROC curve analysis showed that the area under the curve of the model for predicting survival of the patients was 0.885, and the optimal cut-off value was 1.252, as well as the sensitivity, accuracy and positive predictive value were 90.50%, 87.09% and 84.32%, respectively. Conclusions:ECOG-PS score, RDW, FIB, D-D, LDH, and NLR are associated with the survival of KRAS-mutated advanced NSCLC patients treated with immunosuppressants, and the Cox regression model constructed on the basis of the above factors has a good efficacy in predicting the survival of patients.

BACKGROUND: Evidence on the relations of the American Heart Association's ideal cardiovascular health (ICH) with mortality in Asians is sparse, and the interaction between behavioral and medical metrics remained unclear. We aimed to fill the gaps. METHODS: A total of 198,164 participants without cancer and cardiovascular disease (CVD) were included from the China Kadoorie Biobank study (2004-2018), Dongfeng-Tongji cohort (2008-2018), and Kailuan study (2006-2019). Four behaviors (i.e., smoking, physical activity, diet, body mass index) and three medical factors (i.e., blood pressure, blood glucose, and blood lipid) were classified into poor, intermediate, and ideal levels (0, 1, and 2 points), which constituted 8-point behavioral, 6-point medical, and 14-point ICH scores. Results of Cox regression from three cohorts were pooled using random-effects models of meta-analysis. RESULTS: During about 2 million person-years, 20,176 deaths were recorded. After controlling for demographic characteristics and alcohol drinking, hazard ratios (95% confidence intervals) comparing ICH scores of 10-14 vs. 0-6 were 0.52 (0.41-0.67), 0.44 (0.37-0.53), 0.54 (0.45-0.66), and 0.86 (0.64-1.14) for all-cause, CVD, respiratory, and cancer mortality. A higher behavioral or medical score was independently associated with lower all-cause and CVD mortality among the total population and populations with different levels of behavioral or medical health equally, and no interaction was observed. CONCLUSIONS ICH was associated with lower all-cause, CVD, and respiratory mortality among Chinese adults. Both behavioral and medical health should be improved to prevent premature deaths.

Objective:To evaluate the efficacy of Baduanjin combined with mecobalamin tablets in the treatment of type 2 diabetic peripheral neuropathy. Methods:Eighty patients with type 2 diabetic peripheral neuropathy who met the inclusion criteria were randomly divided into two groups with 40 patients in each group ( n=40). The control group took oral mecobalamin tablets and self-management, and the treatment group were treated with Baduanjin on the basis of the control group. All patients were treated for 12 weeks. The clinical symptoms were evaluated by Toronto Clinical Scoring System (TCSS), and the motor nerve conduction velocity (MCV) of tibial nerve and the sensory conduction velocity (SCV) of superficial peroneal nerve were measured by EMG evoked potential instrument. The hemorheological indexes (whole blood low shear viscosity, whole blood high shear viscosity and plasma viscosity) were measured before and after treatment. The clinical efficacy was evaluated and adverse events were recorded. Results:In the course of treatment, 39 patients in each group completed the study with each one dropout. The total effective rate was 87.2% (34/39) in the treatment group and 64.1% (25/39) in the control group. There was significant difference between the two groups ( χ2=5.64, P=0.018). After treatment, the TCSS score of the treatment group was significantly lower than that of the control group ( t=-6.23, P<0.01), the tibial nerve MCV (43.06 ± 4.19 m/s vs. 39.55 ± 4.30 m/s, t=3.65), the superficial peroneal nerve SCV (43.23 ± 4.31 m/s vs. 39.92 ± 3.74 m/s, t=3.62) in the treatment group were significantly higher than the control group ( P<0.001), while the whole blood high shear viscosity, the whole blood low shear viscosity, and the plasma viscosity in the treatment group were significantly lower than the control group ( t value were -10.36, -14.21, -13.88, all Ps<0.001). During the treatment, no serious adverse events occurred in both groups. Conclusion:Baduanjin combined with mecobalamin tablets in the treatment of type 2 diabetic peripheral neuropathy can reduce blood viscosity, promote blood circulation, increase nerve conduction velocity, improve clinical symptoms and signs, and improve clinical efficacy.

Objective:To explore the value of regional cerebral oxygen saturation (rScO 2) and anesthesia depth monitoring in predicting postoperative cognitive dysfunction (POCD) in patients with non-macrovascular surgery. Methods:A retrospective analysis of 147 patients with non-macrovascular surgery under general anesthesia admitted to the First Affiliated Hospital of Xi'an Jiaotong University from August 2017 to June 2019 was performed and divided into the POCD group ( n=37) and the non-POCD group ( n=110) according to the presence/absence of postoperative POCD. The changes of bispectral index (BIS) and rScO 2 in patients before anesthesia induction (T 0), endotracheal intubation (T 1), 2 hours after operation (T 2), after operation (T 3), and at extubation (T 4) were recorded, and the predictive value for the occurrence of POCD was analyzed by receiver operating characteristic (ROC) curve. Results:There was no statistically significant difference in anesthesia time, operation time and operation type between the two groups ( P>0.05). There was no significant difference in BIS and rScO 2 levels between the two groups at T 0, T 1 and T 4 ( P>0.05). BIS and rScO 2 levels in the POCD group at T 2 and T 3 were lower than those in the non-POCD ( P<0.05). Both BIS and rScO 2 of the two groups reached the lowest value at T 2, and the reduction rate of rScO 2 in the POCD group was higher than that in the non-POCD group [(31.84±3.27)% vs (14.81±2.52)%, P<0.05]. The ROC curve of BIS-T 2, rScO 2-T 2, BIS-T 3, rScO 2-T 3, rScO 2 reduction from the baseline value to predict POCD in patients with non-macrovascular surgery was plotted, and the AUCs were 0.514, 0.617, 0.505, 0.633, 0.724, respectively. The highest AUC value of 0.808 was found for combined detection at T 2 (rScO 2 and BIS). Conclusions:The combined detection of intraoperative regional cerebral oxygen saturation and anesthesia depth monitoring is of good clinical application value in predicting postoperative cognitive dysfunction in patients with non-macrovascular surgery.

Objective:To observe the clinical efficacy of electroacupuncture in the treatment of type 2 diabetes mellitus combined with mild and moderate carpal tunnel syndrome.Methods:Eighty patients with type 2 diabetes mellitus combined with mild to moderate carpal tunnel syndrome were randomly divided into two groups with 40 patients in each group ( n=40). In the course of the treatment, 2 patients in each group dropped out, which means 38 patients in each group were included. All patients were instructed to actively control blood glucose The control group was given Mecobalamin tablets orally, while the treatment group was given electroacupuncture of Daling and Neiguan on the affected side based onthe control group for 6 weeks. The degree of pain was assessed by VAS, and the severity of clinical symptoms was assessed by the symptom scale of Boston carpal tunnel questionnaire (BCTQ). The sensory nerve conduction velocity (SCV), the amplitude of sensory nerve action potential (SNAP) and the distal motor latency (DML) were detected by EMG evoked potential instrument. The clinical efficacy was evaluated and adverse events were recorded. Results:The total effective rate was 81.6% (31/38) in the treatment group and 60.5% (23/38) in the control group, and the difference was statistically significant ( χ2=5.094, P=0.024). After the treatment, the scores of VAS and BCTQ in the treatment group were lower than those of the control group ( t=2.639, 2.790, P=0.010, 0.007); DML (3.62 ± 0.19 ms vs. 4.00 ± 0.17 ms, t=68.891) in the treatment group was lower than that of the control group ( P<0.01), while SCV (47.36 ± 0.18 m/s vs. 42.34 ± 0.14 m/s, t=97.163) and SNAP (14.74 ± 0.18 μV vs. 12.10 ± 0.16 μV, t=51.434) in the treatment group were higher than those of the control group ( P<0.01). During the treatment, no serious adverse events occurred in two groups. Conclusions:Electroacupuncture is safe and effective in the treatment of mild and moderate carpal tunnel syndrome with type 2 diabetes. It can reduce the degree of pain and improve the symptoms of wrist joint.

OBJECTIVE: To assess the reliability and validity of Adversity Quotient Scale in evaluating the adversity quotient among nurses. METHODS: A total of 409 nurses were selected as study subjects from three first-class hospitals in Fujian Province by cluster sampling method. The adversity quotient was investigated by Adversity Quotient Scale and its reliability and validity were tested. RESULTS: The Cronbach′s alpha coefficient, Spearman-Brown coefficient, Guttman Split-Harf coefficient and retest reliability of Adversity Quotient Scale were 0.931, 0.826, 0.823 and 0.940, respectively.
