Objective:To examine the validity and reliability of the Chinese version of the Body Acceptance by Others Scale-2(BAOS-2)in adults.Methods:Totally 616 adults(aged 18-56 years)were selected to test the structural validity,and internal consistency reliability of the scale.The Body Appreciation Scale-2(BAS-2),Func-tionality Appreciation Scale(FAS),Self-Compassion Scale(SCS),Self-Esteem Scale(SES)and Satisfaction with Life Scale(SWLS)were used as criteria to test criterion validity.A sample of 55 adults was retested 2 weeks later for the test-retest reliability.Results:The exploratory factor analysis extracted one factor,and the factor loading range of each item was 0.59-0.76.The confirmatory factor analysis showed that the factor model fit indices were acceptable(x2/df=2.99,CFI=0.91,GFI=0.90,TLI=0.89,RMR=0.04,RMSEA=0.08).The scores of the Chinese version of BAOS-2 were positively correlated with the scores of BAS-2,FAS,SCS,SES and SWLS(r=0.43-0.66,Ps＜0.001).The Cronbach a of the Chinese version of BAOS-2 was 0.90,and the test-retest reliabili-ty(ICC)was 0.65.Conclusion:The Chinese version of the Body Acceptance by Others Scale-2(BAOS-2)has i-deal validity and reliability.

Objective:To evaluate the efficacy of perioperative analgesia with esketamine in the patients undergoing thoracoscopic surgery.Methods:A total of 90 patients of either sex, aged 18-64 yr, with body mass index of 18-30 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, scheduled for elective thoracoscopic lobectomy under general anesthesia, were divided into 3 groups ( n=30 each) by a random number table method: control group (C group) and different doses of esketamine groups (S 1 group, S 2 group). Before induction of anesthesia, esketamine 0.1 and 0.2 mg/kg were intravenously injected in S 1 group and S 2 group, respectively, while esketamine was not given in group C. Anesthesia was routinely induced in all the three groups. During anesthesia maintenance, esketamine 0.1 and 0.2 mg·kg -1·h -1 were intravenously infused in group S 1 and group S 2, respectively, and the remaining drugs used for anesthesia maintenance were the same in the three groups. Patient-controlled intravenous analgesia (PCIA) was used after operation, and PCIA solution contained sufentanil 2 μg/kg in group C, and esketamine 1 mg/kg was mixed on the basis as previously described in S 1 and S 2 groups. Aminotriol ketorolac was given as rescue analgesia to maintain numeric rating scale score at rest ≤3. The total amount of propofol and remifentanil during operation, effective pressing times of PCIA in postoperative 0-24 h and >24-48 h periods, and requirement for rescue analgesia were recorded. The occurrence of adverse reactions such as respiratory depression, nausea and vomiting, dizziness and salivation, and emergence time were recorded after surgery. The serum interleukin-6 (IL-6) concentration was measured by enzyme-linked immunosorbent assay at 30 min before and after surgery, and the malondialdehyde (MDA) concentration in serum was measured by thiobarbituric acid colorimetric analysis. The postoperative recovery was assessed using the 50-item quality of recovery scale at 1 and 2 days after surgery. The development of chronic pain was followed up by telephone within 1-3 months after surgery. Results:Compared with group C, the intraoperative consumption of remifentanil, effective pressing times of PCIA in postoperative 0-24 h and >24-48 h periods, rate of rescue analgesia, and postoperative serum IL-6 concentration were significantly decreased, and the 50-item quality of recovery scale score was increased in S 1 and S 2 groups, and the postoperative serum MDA concentration was significantly decreased in group S 2 ( P<0.05). Compared with group S 1, the consumption of intraoperative remifentanil was significantly decreased ( P<0.05), and no significant change was found in postoperative serum IL-6 and MDA concentrations in group S 2 ( P>0.05). Compared with group S 2, the postoperative emergence time was significantly shortened in S 1 and C groups ( P<0.05). There was no statistically significant difference in the intraoperative consumption of propofol, incidence of adverse effects and incidence of chronic pain among the three groups ( P>0.05). Conclusions:Esketamine for perioperative analgesia (dose before anesthesia induction 0.1 mg/kg, dose for maintenance of anesthesia 0.1 mg·kg -1·h -1, dose for postoperative PCIA 1 mg/kg) can raise the quality of analgesia and improve the quality of early postoperative recovery in the patients undergoing thoracoscopic lobectomy.

Objective:To investigate the effect of nuclear transcription factor kappa B (NF-κB)/NOD-like receptor family pyrin domain containing protein 3 (NLRP3) pathway on lipid deposition and autophagy related protein expressions in aortic atherosclerosis mice.Methods:Ten 6-week-old male C57BL/6 mice were used as control group, and 20 male apolipoprotein E gene knockout ( ApoE-/-) mice at the same age were randomly divided into AS group and bortezomib (BTZ) group ( n=10). Mice in the AS group and BTZ group were fed with high-fat diet for 8 weeks; and then, mice in the BTZ group were injected intraperitoneally with 50 μg/kg BTZ (twice a week, for 4 weeks), while mice in the AS group were injected with same amount of saline. The general states of mice in each group were observed during the experiment process. Twelve weeks after intervention, the body weight and the levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) were measured; the pathological morphology and lipid deposition of plaques at the aortic roots were observed by oil red O staining and HE staining; the expressions of NF-κB and NLRP3 were detected by immunohistochemistry; the expressions of Beclin-1, P62, and Atg12 were measured by Western blotting. Results:After 12 weeks of intervention, the body weight, contents of TC and LDL, pathological degrees, proportion of lipid deposition, positive expressions of NF-κB and NLRP3, and P62 protein expression in the AS group and BTZ group were significantly higher than those in the control group, while these indexes in the BTZ group were significantly lower than those in the AS group ( P<0.05); HDL content, protein expression levels of Beclin-1 and Atg12 in the AS group and BTZ group was significantly lower than that in the control group, while these indexes in the BTZ group were significantly higher than those in the AS group ( P<0.05). Conclusion:Inhibition of NF-κB/NLRP3 pathway can reduce lipid deposition by regulating lipid content and mediate the autophagy related protein expressions to promote autophagy, thereby inhibiting the process of AS.

Background and Objectives: RUNX2 plays an essential role during the odontoblast differentiation of dental pulp stem cells (DPSCs). RUNX2 Exon 5 is an alternative exon and essential for RUNX2 transcriptional activity. This study aimed to investigate the regulatory mechanisms of RUNX2 exon 5 alternative splicing in human DPSCs. Methods: and Results: The regulatory motifs of RUNX2 exon 5 were analyzed using the online SpliceAid program. The alternative splicing of RUNX2 exon 5 in DPSCs during mineralization-induced differentiation was analyzed by RT-PCR. To explore the effect of splicing factor YBX1 on exon 5 alternative splicing, gaining or losing function of YBX1 was performed by transfection of YBX1 overexpression plasmid or anti-YBX1 siRNA in DPSCs. Human RUNX2 exon 5 is evolutionarily conserved and alternatively spliced in DPSCs. There are three potential YBX1 binding motifs in RUNX2 exon 5. The inclusion of RUNX2 exon 5 and YBX1 expression level increased significantly during mineralization-induced differentiation in DPSCs. Overexpression of YBX1 significantly increased the inclusion of RUNX2 exon 5 in DPSCs. In contrast, silence of YBX1 significantly reduced the inclusion of exon 5 and the corresponding RUNX2 protein expression level. Knockdown of YBX1 reduced the expression of alkaline phosphatase (ALP) and osteocalcin (OC) and the mineralization ability of DPSCs, while overexpression of YBX1 increased the expression of ALP and OC and the mineralization ability of DPSCs. Conclusions Human RUNX2 exon 5 is conserved evolutionarily and alternatively spliced in DPSCs. Splicing factor YBX1 promotes the inclusion of RUNX2 exon 5 and improves the mineralization ability of DPSCs.

Objective:To investigate the clinical characteristics of the coronavirus disease 2019 (COVID-19) with liver injury and to provide evidence for clinical diagnosis and treatment.Methods:The clinical data of 107 cases of COVID-19 with liver injury admitted to Guangzhou Eighth People′s Hospital from January 20, 2020 to February 17, 2020 were retrospectively analyzed. SPSS 20 was used for statistical analysis. Comparison of data between the two groups was performed by Mann-Whitney U test, and P<0.05 was statistically significant. Results:The proportion of COVID-19 patients with liver injury was 38.5%. Among the 107 patients, 53 were males and 54 were females, with a median age of 57 years. Among the 52 cases with basic diseases, 20(38.5%) cases had chronic liver diseases(including fatty liver and viral hepatitis). Patients had clinical manifestations of fever (86.0%), cough (92.5%), nausea and vomiting (29.0%), and diarrhea (21.5%). All the indexes of liver function were abnormal in different degree, 31.8% of patients had the total bilirubin (TB) increased, while 60.7% and 63.6% of patients had alanine aminotransferase (ALT) and aspartate aminotransferase (AST) increased respectively. The serum albumin (ALB), prealbumin (PAB), cholinesterase (CHE), prothrombin activity (PTA) decreased in 86.9%, 88.8%, 17.8% and 7.5% of patients, respectively. The level of TB, ALT, AST was higher in patients with severe or critical disease than in patients with light or common disease( Z=-2.3089, P=0.037; Z=-2.611, P=0.009; Z=-3.298, P=0.001), while ALB, PAB, CHE, PTA decreased more significantly( Z=5.527, P=0.000; Z=-2.324, P=0.020; Z=-3.119, P=0.002). Compared with the patients without basic chronic liver disease, the transaminase of the patients with basic chronic liver disease increased more significantly ( Z=-2.218, P=0.027; Z=-1.982, P=0.047). The TB level of patients treated with LPV/r was significantly higher than that of patients without LPV/r ( Z=-3.079, P=0.002). Conclusions:Liver injury is one of the common complications of COVID-19. Patients in severe or critical condition and with basic chronic liver diseases have severe liver injury. We should pay more attention to the liver injury effect of drugs.

OBJECTIVE: To compare the accuracy of five warfarin-dosing algorithms and warfarin stable dose model (2.5 mg/day) for Shandong population. METHODS: One hundred and twenty five patients who achieved stable warfarin dose were enrolled. Clinical and genetic data were used to evaluate the value of each algorithm by calculating the percentage of patients whose predicted warfarin dose was within 20% of the actual stable therapeutic dose and mean absolute error (MAE). RESULTS: The frequency of patients with CYP2C9*1/*1, CYP2C9*1/*3 and CYP2C9*1/*2 genotype was 92.00%, 7.20%, 0.80%, respectively. That of VKORC1-1639 AA, AG and GG genotype was 82.40%, 15.20%, 2.40%, respectively. CYP4F2*1/*1, *1/*3, *3/*3 genotype was 50.40%, 39.20%, 10.40%, respectively. With the same genotypes for other loci, patients who carried at least one VKORC1-16398G mutant allele had increased warfarin stable daily dose compared with VKORC1-1639AA. Compared with CYP4F2*1/*1, those carrying at least one CYP4F2*3 mutant allele had warfarin stable daily dose increased by 5.9%-13.00%. The percentage of ideal prediction calculated from IWPC model (59.20%), Huang model (57.60%) and Ohno model (52.80%) were higher than others. The MAE were 0.35 (95%CI: 0.11-0.49), 0.15 (95%CI: 0.10-0.32), 0.39 (95%CI: 0.12-0.51), respectively. CONCLUSION The polymorphisms of CYP2C9, VKORC1 and CYP4F2 genes can influence the stable dose of warfarin in Shandong population. IWPC algorithm is suitable for guiding the use of warfarin in this population.

The outbreak of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 has rapidly spread globally. Cancer patients are at a higher risk of being infected with the coronavirus and are more likely to develop severe complications, as compared to the general population. The increasing spread of COVID-19 presents challenges for the clinical care of patients with gynecological malignancies. Concerted efforts should be put into managing gynecological malignancies in an orderly manner by strictly implementing the measures that are specifically developed for controlling the spread of COVID-19. We have drafted Recommendations on Management of Gynecological Malignancies during the COVID-19 Pandemic based on our experience on controlling COVID-19 pandemic in China. We recommend that patients with gynecological malignancies should be managed in hierarchical and individualized manners in combination with local conditions related to COVID-19. Medical care decision should be balanced between controlling COVID-19 pandemic spread and timely diagnosis and treatment for gynecologic oncology patients.

This study measured the in vitro inhibitory effects of α-amylase(AM), α-glycosidase(AG)and aldose reductase(AR)extraction from Potentilla fruticosa in three solvents: water extract(WE)and 95% methanol extraction of petroleum ether part(MEP), 95% methanol extraction of ethyl acetate part(MEE)and 95% methanol extraction of water part(MEW)through α-amylase inhibitors(AMI), α-glycosidase inhibitors(AGI)and aldose reductase inhibitors(ARI)activity screening models. In vivo effects of different solvents from Potentilla fruticosa on impaired glucose tolerance of mice were also measured. Among them, WE, MEP and MEE exhibited against AMI activity with IC50 values of 0. 432, 1. 193 and 0. 507 mg/mL, respectively. Three solvents against AGI activity with IC50 values of 0. 164, 0. 768 and 0. 466 mg/mL, respectively. Three solvents against ARI activity with IC50 values of 0. 742, 2. 158 and 1. 098 mg/mL, respectively. The study suggests that Potentilla fruticosa in water extract and 95% methanol extraction of ethyl acetate part demonstrated a stronger inhibitory effect on AM, AG and AR. Meanwhile, Potentilla fruticosa in water extract and 95% methanol extraction of ethyl acetate part can be significantly decreased the postprandial blood glucose in mice.
