Objective To investigate the effect of Osteoporosis Self-Assessment Tool for Asia(OSTA)index on brachial ankle pulse wave velocity(baPWV)and its predictive value for peripheral atherosclerosis in menopausal women.Methods A total of 1 138 menopausal women who underwent physical examination at our hospital from January 2022 to December 2022 were enrolled in the study.General clinical data were collected,the OSTA index was calculated,and baPWV was measured.Patients were divided into the control group(n=539)and the peripheral atherosclerosis group(n=599)according to the baPWV values(peripheral atherosclerosis occurs with baPWV≥1 400 cm/s).Linear regression and Logistic regression were used to analyze the effect of OSTA index on baPWV in menopausal women.The predictive value of peripheral atherosclerosis was evaluated using the receiver operating characteristic(ROC)curve.Results The OSTA index was lower in the peripheral atherosclerosis group than that in the control group[-0.40(-2.20,1.00)vs.0.40(-0.60,1.40),P＜0.05].Univariate linear regression analysis was used to conclude that the OSTA index was an influencing factor of baPWV,and after correcting for risk factors,multivariate linear regression analysis indicated that OSTA index still affected the value of baPWV(P＜0.05).The linear regression equation was baPWV=-27.911-39.752×OSTA+6.444×SBP+7.008×DBP+11.506×HCY+27.942×Hs-CRP.Logistic regression analysis suggested that increased OSTA index was a protective factor for peripheral atherosclerosis(OR=0.664,95%CI:0.535-0.823,P＜0.001).ROC curve analysis suggested that OSTA index was-1.25 as the optimal cutoff point,which predicted peripheral atherosclerosis with an area under the curve of 0.619,a sensitivity of 36.2%and a specificity of 86.3%.Conclusion In menopausal women,OSTA index is an influential factor for baPWV,and increased OSTA index is a protective factor against peripheral atherosclerosis,which can be used to predict baPWV value.

"Xuanfu",as the microscopic structure in TCM theory of visceral manifestations,spreads all over the human body.The microscopic pathological changes of acute ulcerative colitis are manifested as cryptic abscesses or even structural disorders of the colon.Its damp heat accumulates in the large intestine,and the pathogenic characteristics of the large intestine coincides with the concept of"Xuanfu"that likes opening and avoiding closing.The functions of the mechanical barrier and mucus barrier in the intestinal crypt are very similar to the characteristics of the"Xuanfu",which can provide morphological basis for the"Xuanfu"theory of the intestine.The method of clearing away and opening the"Xuanfu"can inhibit the"Xuanfu closed"state of the intestine caused by the accumulation of damp and heat,and promote the guiding role and theoretical support of the"Xuanfu-crypt"theory in the treatment of early crypt lesions of ulcerative colitis.

Objective:To explore the application effect of parent-child emotional regulation and resilience group training in adolescent depression patients.Methods:From August 2020 to September 2021, a total of 118 adolescent depression patients were enrolled and randomly divided into the intervention group(66 cases) and the control group(66 cases) by a random number table method.The intervention group received medication therapy and parent-child group emotional regulation and psychological resilience training, while the control group received medication therapy and commonly used individual, family or group therapy in clinical practice.The Hamilton Depression rating scale(HAMD-24 version), Herth hope scale(HHS), Connor-Davidson resilience scale(CD-RISC), and family adaptability and cohesion evaluation scale, second edition Chinese version(FACES-Ⅱ-CV) were adopted to investigate participants at baseline, 12-week, 24-week, and 36-week after intervention.SPSS 26.0 statistical software was used to perform repeated measurement analysis of variance on the data.Results:(1)The interaction effect between two groups of HAMD scores( F=54.0, P<0.001), group main effect( F=401.4, P<0.001), and time main effect( F=116.6, P<0.001) were all significant.Further simple effect analysis showed that there were statistically significant differences in HAMD scores at various time points after intervention between the intervention group(26.2±6.5, 19.3±5.9, 11.3±5.6) and the control group(33.1±9.1, 30.3±7.9, 25.0±8.4)(all P<0.05). Intragroup comparison showed the HAMD scores of the intervention group and control group at each time point after intervention were lower than those before intervention (all P<0.05). (2)The interaction effect of CD-RISC scores between two groups of patients( F=72.1, P<0.001), group main effect( F=48.9, P<0.001), and time main effect( F=174.9, P<0.001) were significant.Further simple effect analysis showed that the CD-RISC score of the intervention group at each time point after intervention were higher than those of the control group(all P<0.05). Intragroup comparison showed the scores of CD-RISC at each time point after intervention in the intervention group and the control group were higher than those before intervention(all P<0.05). (3)The interaction effect of HHS scores( F=121.6, P<0.001), group main effect( F=57.4, P<0.001), and time main effect( F=208.1, P<0.001) of the two groups of patients were significant.Further simple effect analysis showed that the HHS scores of the intervention group were higher than those of the control group at all time points after intervention(all P<0.05). Intragroup comparison showed the HHS scores of the intervention group and the control group at each time point after intervention were higher than those before intervention(all P<0.05). (4)The interaction effect of FACES-Ⅱ-CV scores( F=45.0, P<0.001), group main effect( F=20.3, P<0.001), and time main effect( F=154.5, P<0.001) of the two groups of patients were significant.Further simple effect analysis showed that the FACES-Ⅱ-CV scores of the intervention group were higher than those of the control group at all time points after intervention(all P<0.05). Intragroup comparison showed the FACES-Ⅱ-CV scores of the intervention group and the control group at each time point after intervention were higher than those before intervention(all P<0.05). (5)The total effective rate of the intervention group was higher than that of the control group(95.1%, 87.7%)( P<0.001). Conclusion:In adolescents with depression, parent-child group emotional regulation and resilience training can effectively reduce depression emotion, increase the level of hope and resilience of patients and enhance family intimacy and adaptability.

Objective:To investigate the pharmacokinetics of sugammadex in reversal of rocuronium-induced muscle relaxant residual in infants and young children undergoing daytime surgery.Methods:One hundred and four pediatric patients of either sex, aged 3-36 months, of American Society of Anesthesiologists Physical Status classification Ⅱ, with body mass index of 18.5-28.0 kg/m 2, diagnosed with oblique inguinal hernia and/or hydrocele, scheduled for laparoscopic high ligation of hernia sac and/or high ligation of sphingoid surgery, were included in the study. Intraoperative neuromuscle relaxation was assessed by transdermal stimulation of the ulnar nerve in the wrist using a TOF Guard monitor. Rocuronium 0.9 mg/kg, propofol 3 mg/kg, and sufentanyl 0.5 μg/kg were intravenously injected for anesthesia induction, and propofol 6-8 mg·kg -1·h -1 was intravenously infused to maintain anesthesia. The pediatric patients were divided into Ⅰgroup and Ⅱ group according to the degree of postoperative neuromuscular block. In group Ⅰ, sugammadex 2 mg/kg was intravenously injected when TOF returned to T 2 recurrence. In group Ⅱ, sugammadex 4 mg/kg was intravenously injected when the single stimulation count was 1 or 2 after tetanic stimulation. At 2 and 10 min after rocuronium administration, at the end of operation, 2 and 10 min after sugammadex administration, and when the children met the standard of leaving the resuscitation room, venous blood samples were collected for determination of plasma concentrations of rocuronium and sugammadex using ultra-high performance liquid chromatography-mass spectrometry. Pharmacokinetic parameters were determined using the Pheonix WinNonlin software. The onset of rocuronium and time for recovery of TOF ratio to 90% were recorded. Results:The pharmacokinetics of sugammadex was fitted to the nonlinear mixed-effect satrioventricular model.There was no significant difference in the peak concentration, area under the drug concentration-time curve, elimination half-life, apparent clearance, apparent volume of distribution, mean retention time, and time for TOF ratio returning to 90% between the two groups ( P> 0.05). Conclusions:The pharmacokinetics of sugammadex in reversal of rocuronium-induced muscle relaxant residual is fitted to a nonlinear mixed-effect satrioventricular model, and sugammadex 2 and 4 mg/kg have similar pharmacokinetics in infants and young children undergoing daytime surgery.

Objective:To construct a Discharge Preparation Service Demand Assessment Scale for Psychiatric Patients with Depression.Methods:Convenience sampling was used to select 25 experts from fields such as psychiatric nursing, psychiatric management, and rehabilitation treatment as the subject of the consultation. On the basis of literature review and clinical experience, the research group used the Delphi method to conduct two rounds of consultation with 25 experts, forming a Discharge Preparation Service Demand Assessment Scale for Psychiatric Patients with Depression. The enthusiasm of experts was evaluated using the effective response rate of the questionnaires. The authority level of experts was assessed using an authority coefficient. The concentration of expert opinions was evaluated using the mean of item importance assignment and coefficient of variation. The degree of coordination of expert opinions was represented by the Kendall coordination coefficient.Results:The effective response rates of the two rounds of consultation questionnaires were all 100%, with expert authority coefficients of 0.890 and 0.904, and the Kendall coordination coefficients of expert opinions of 0.247 and 0.203 ( P<0.05) . The Discharge Preparation Service Demand Assessment Scale for Psychiatric Patients with Depression was constructed, which included 10 dimensions and 38 items. Conclusions:The Discharge Preparation Service Demand Assessment Scale for Psychiatric Patients with Depression is scientific and reliable, which can provide a basis for clinical nurses to evaluate the discharge preparation service demands of psychiatric patients with depression.

Objective:To investigate the association of osteosarcopenia with falls, risk of fracture, malnutrition among middle-aged and elderly adults.Methods:A total of 253 participants dwelling in Guangzhou community aged 40-90 years were included in this cross-sectional study from December 2017 to December 2019.Bone mineral density(BMD)was detected by dual-energy X-ray absorptiometry(DEXA). Body composition was analyzed by a bioelectrical impedance analysis.Handgrip strength and gait speed were examined.The 10-year probability of a major osteoporotic fracture and hip fracture were evaluated by online WHO fracture risk assessment tool( FRAX?). Results:According to diagnostic criteria of AWGS and EWGSOP2, the incidences of osteosarcopenia varied from 5.1% to 7.6%, 5.1% to 11.4% respectively.After the adjustment for age and gender, Logistic regression analysis showed that osteosarcopenia was correlated with falls, risk of fracture and malnutrition.Osteosarcopenia definited by AWGS criteria was strongly correlated with falls( OR=3.27-5.68, P<0.05), osteosarcopenia definited by non-severe sarcopenia criteria was strongly correlated with the risk of hip fracture( OR=1.14-1.15, P<0.05), and fat-free mass index was strongly correlated with osteosarcopenia with different definitions( OR=0.21-0.48, P<0.05). Conclusions:Osteosarcopenia is associated with higher risk of falls, fracture and malnutrition in the Guangzhou community-dwelling middle-aged and elderly adults, and fat-free mass index is an independent risk factor for osteosarcopenia.

Objective:To investigate the changes of gene or protein expression and activity of matrix metalloprotein9 (MMP9) and tissue inhibitor ofmetalloproteinasel (TIMP1) in the carotid artery (CA) of 4 wk hindlimb unweighted rat.Methods:A 4 weeks(wk) hindlimb unweighted (HU) rat model was used to simulate the effect of weightlessness on the cardiovascular system.Transmission electron microscopy was used to detect the content of ECM.Reverse transcriptase polymerase chain reaction(RT-PCR) was conducted to measure the mRNA content MMP and TIMP1.Immunohistochemistry and Western blot technique were used to measure the protein abundance.Gelatin zymography was carried out to detect the activity of MMP9.Results:Compared to the control group (CON),the area of ECM was enhanced (P＜0.05) and the content of collage fiber was increased (P＜0.05) in the CA of HU rats;moreover,HU did not affect the mRNA expression of MMP9,but significantly reduced the protein content (P＜0.05) or enzymatic activity (P＜0.05).Accordingly,the mRNA or protein expression of TIMP1 in the CA was significantly increased by HU (P＜0.05).Conclusion:Simulated weightlessness caused imbalance between MMP and TIMP1 expression,which might contribute to the ECM aggregation and stiffness of CA.

Objective To investigate the sensitivity of common carotid arteries of the rats to ceramide (Cer) regulation after simulated weightlessness.Methods Fourty-eight male Sprague-Dawley rats that matched for weight were randomly assigned to suspended group (n=24) and control group (n =24).Tail suspension of rats was carried out for 4 wk to simulate the effect of weightlessness.Isometric force recording system was used to detect the vasoconstriction and vasodilation response of common carotid arteries ring.Dihydroethidium fluorescent probe was used to evaluate the level of superoxide anion (O2-·) in arteries.Results Vasoconstriction response and vasodilation response showed insignificant difference between suspended group and control group.Incubation with C6-ceramide (C6-Cer) or Cer antibody (anti-Cer) did not change the vasoconstriction response and O2-· level of CA in control group but increased Cer level,vasoconstriction response to KCl and O2-· level of common carotid arteries in control group,and did not change the vasodilation response of common carotid arteries both in control and suspended group.In suspended group,C6-Cer incubation increased vasoconstriction response of common carotid arteries both to potassium chloride and phenylephrine,as well as the O2-· level (t=6.077-12.630,P＜0.05) but less to acetylcholine and nitroprusside sodium.The anti-Cer incubation decreased response vasoconstriction of common carotid arteries in suspended both to potassium chloride and phenylephrine,as well as the O2-· level (t=11.582 32.130,P＜0.05) but the vasodilation response.The incubation of superoxide dismutase or hydrogen peroxide depressed the changes of vasoconstriction response caused by C6-Cer or anti-Cer.Conclusions Cer regulation increases the sensitivity of common carotid arterial constriction in the simulated weightless rats and the mechanism is concerned with reactive oxygen level.

OBJECTIVE: To evaluate the value of X-ray fluoroscopy in preventing catheter dysfunction during catheterization of peritoneal dialysis. METHODS: A total of 168 patients with end-stage renal failure were nonrandomized into group A (the conventional catheterization group) and group B (the conventional catheterization + bedside fluoroscopy group). All patients were followed up for 1 year after the catheterization. Details of the patients' general information, catheter-related complications and incidence of catheter dysfunction were analyzed. RESULTS: Hemorrhagic complications occurred in 9 patients (5.36%), including 2 incision hematomas, 4 bloody fluid drainages, 1 bladder perforation and 1 intestinal perforation (1.20%). Dialysate leakages occurred in 4 patients (2.38%): 2 right pleural effusion and 2 scrotal edemas. Infection-related complications (2.98%) in 5 patients were observed: 1 infectious peritonitis and 4 catheter exit infections. All peritoneal dialysis-related infections were cured after the treatment. There was no significant difference in the incidence of mechanical and infectious complications between the two groups (P> 0.05). No immediate catheter dysfunction was found in all patients, but late catheter dysfunction was observed in 14 patients (8.33%), including 9 catheter migrations (5.36%), 5 of which were induced by other reasons (2.98%). Catheter dysfunction in 11 out of the 14 patients occurred within 30 days post-catheterization, whereas 2 occurred over 30 days (caused by constipation). In group A, 12 patients developed delayed catheter dysfunction (11.65%), 10 of which (83.33%) were induced by catheter migration and the other 2 by other reasons. In group B, 2 (11.65%) delayed catheter dysfunctions were observed, including 1 catheter migration and 1 constipation. The incidence of catheter dysfunction in group A was significantly higher than that in group B (P<0.05). The success rate of catheterization in group B was 91.3%. CONCLUSION Catheter dysfunction is a common complication in peritoneal dialysis. X-ray fluoroscopy during catheter insertion helps to monitor the location of the catheter, which can effectively prevent late catheter dysfunction and increase the success of catheterization in peritoneal dialysis.
