Objective:The study aimed to validate the Neuroception of Psychological Safety Scale (NPSS) in terms of reliability and validity among individuals with mental disorders in China.Methods:The Study followed Brislin′s translation principles to adapt the scale into Chinese. From February to June 2023, a total of 638 hospitalized patients with mental disorders (477 with schizophrenia and 161 with mood disorders) were selected through gender-stratified simple random sampling from the Shanghai Pudong New Area Mental Health Center and the Shanghai Baoshan Mental Health Center. The Chinese version of the NPSS and the Security Questionnaire (SQ) were administered. The reliability of the scale was measured using split-half reliability and test-retest reliability. Validity was assessed through content validity, structural validity, convergent validity, and discriminative validity analyses. In addition, SQ was used as a criterion tool to test the validity of the criterion through Pearson correlation analysis.Results:The Chinese version of the NPSS contained 29 items, with total scores ranging from 29 to 145. Higher total scores indicated greater psychological safety. Item analysis showed a decider value of 10.58 to 20.80 (>3), and the correlation between items and total scores ranged from 0.579 to 0.749 (all P<0.05). The item-level content validity index (I-CVI) for the items ranged from 0.86 to 1.00, while the average scale-level content validity index (S-CVI/Ave) was 0.99. Exploratory factor analysis extracted three common factors: social participation, empathy, and bodily sensations, which is consistent with the structure of the original scale, explaining a cumulative variance contribution rate of 62.551%. Confirmatory analysis revealed a satisfactory model fit, with average variance extracted (AVE) values for the three dimensions ranging from 0.523 to 0.645, and composite reliability(CR) ranging from 0.905 to 0.938. The standard loading coefficients for the items ranged from 0.608 to 0.859, and inter-factor correlation coefficients were all smaller than the square roots of their respective AVE values. Pearson correlation analysis indicated significant positive relationships between the Chinese NPSS and SQ ( r=0.822-0.846, P<0.01). Reliability analysis showed Cronbach′s alpha coefficients of 0.903-0.959 for the total scale and subscales. After a 3-week interval, test-retest reliability (70 patients) ranged from 0.874 to 0.983, and split-half reliability was 0.869-0.969. All model fit indices met established criteria. Conclusions:The Chinese version of the NPSS demonstrates good reliability and validity, making it suitable for both research and clinical applications in assessing psychological security among individuals with schizophrenia and mood disorders.

To explore the prevalence and related risk factors of osteoporosis (OP) in the elderly ≥60 years old in Jiuting Town, Songjiang District, Shanghai City. A total of 2 175 local residents aged ≥60 years old who participated in the questionnaire survey at the physical examination center of Jiuting Community Health Service Center, Songjiang District, Shanghai City from July 2021 to December 2022 were selected by a cross-sectional study with multi-stage sampling method. Questionnaire survey, blood test and bone mineral density (BMD) test were conducted.The differences in all the parameters among the elderly with different bone mass level were analyzed using t-test, chi-square test, binary logistic regression was used to screen the potential risk factors of OP.The results showed that the prevalence of OP in the elderly aged≥60 years old in Jiuting Town was 45.89%.The prevalence of OP increased gradually with the advanced age. The prevalence rate of male was significantly lower than that of female( χ2=211.94, P<0.01).Single factor analysis showed that Dairy products( χ2=9.01, P<0.05), taking calcium( χ2=42.88, P<0.05), physical exercise( χ2=24.73, P<0.05), exercise time( χ2=76.40, P<0.05) and sun exposure( χ2=55.71, P<0.05) were the protective factors for osteoporosis. Multifactor analysis showed that female( wald χ 2=71.46, P<0.001) were the risk factors for osteoporosis. The age of the osteoporosis group was older than that of the non-osteoporosis group [osteoporosis group (72.47±6.89) years old, non-osteoporosis group (68.73±6.34) years old, and the difference was statistically significant, t=-11.67, P<0.05]. The waist circumference, alanine aminotransferase (ALT), creatinine (CR), blood urea nitrogen (BUN) and uric acid (UA) in the non-osteoporosis group were higher than those in the osteoporosis group, and the difference was statistically significant (all P<0.05). The levels of high-density lipoprotein (HDL)[osteoporosis group (1.34±0.35) mol/L, non-osteoporosis group (1.41±0.35) mol/L, t=-4.51, P<0.05] and alkaline phosphatase (ALP)[osteoporosis group (88.46±25.65) mol/L, osteoporosis group (94.56±32.32) mol/L, t=-4.79, P<0.05] in the osteoporosis group were lower than those in the non-osteoporosis group.Low awareness of the knowledge of osteoporosis risk factors(smoking, drinking coffee, high salt and drinking alcohol are 47.28%, 24.15%, 47.79% and 44.90%, respectively), diagnosis and treatment(The symptoms, prognosis, screening methods, medication time and follow-up screening time of osteoporosis were 26.87%, 17.88%, 21.77%, 6.65% and 15.99%, respectivel) and prevention(exercise mode, high calcium food, optimal age of calcium supplementation, the effect of vitamin D on OP, and the appropriate amount of milk to prevent osteoporosis were 33.16%, 42.01%, 13.27%, 12.07%, 9.01%, respectively) were in Jiuting Town. In conclusion, the prevalent rate of OP in the elderly ≥60 years old in Jiuting Town is 45.89%.The main risk factors are female and advanced age. Drinking tea, dairy products, combination of meat and vegetable, taking calcium, physical exercise and sun exposure were the protective factors for osteoporosis. The awareness rate of osteoporosis related knowledge is low, and health education should be strengthened in order to control and prevent the occurrence and development of osteoporosis.

Objective To investigate the effects of Chinese medicine prescription Yiqi Congming Decoction on the expressions of matrix metalloproteinase-2(MMP-2)and phosphorylated c-Jun N-terminal kinase(p-JNK)in the scleral tis-sues of rats with lens-induced myopia(LIM).Methods A total of 60 male and female specific-pathogen-free 21d Sprague Dawley rats without eye disease were included.The right eye was selected.These rats were randomly divided into the blank(BG)group,model(MG)group,low-dose traditional Chinese medicine(LG)group,medium-dose traditional Chi-nese medicine(MD)group,high-dose traditional Chinese medicine(HG)group and western medicine(WG)group,with 10 rats in each group.The-5 D myopic defocus lens was polished to a circle with a diameter of about 1.7 cm with small holes made on both sides and sewed on the upper and lower eyelid skin of the right eye of rats in the MG,LG,MD,HG and WG groups to build a LIM model.Intragastric administration was initiated 4 weeks after molding.Rats in the WG group were given 0.1 g·L-1 atropine eye drops,rats in the BG group did not receive any intervention,rats in the LG,MD and HG groups were administered with Yiqi Congming Decoction intragastrically,and rats in the MG and BG groups were given normal saline by intragastric administration.The axial length of rats in each group was recorded before,4 weeks and 8 weeks after modeling.The rats were sacrificed after 8 weeks of modeling.Hematoxylin-eosin(HE)staining was used to observe the histomorphological changes of sclera in rats.The protein expressions of MMP-2 and p-JNK in the sclera of rats were detected by Western blot.The positive expression of MMP-2 in the scleral tissues of rats was detected through immu-nohistochemistry.The diameter of the scleral collagen fibers of rats in each group was observed by a transmission electron microscope.Results At 4 weeks and 8 weeks after modeling,compared with the BG group,the axial length of rats in the MG group significantly increased(both P＜0.001);compared with the MG group,the axial length of rats showed a sig-nificant decrease in the WG,LG,MD and HG groups(all P＜0.05).At 8 weeks after modeling,the scleral collagen fibers of rats in the BG group were arranged regularly and ran normally.Compared with the BG group,the scleral collagen fibers of rats in the MG group were distributed sparsely with obvious fiber gaps and arranged irregularly;compared with the MG group,the arrangement of scleral collagen fibers in the MD and HG groups was more regular,and the space between fibers was smaller,while the collagen fibers between scleral layers in the LG and WG groups were relatively clear and compact.Compared with the BG group,the expressions of MMP-2 and p-JNK in the sclera of rats in the MG group significantly in-creased(both P＜0.001);compared with the MG group,the expressions of MMP-2 and p-JNK in the sclera of rats in the WG,LG,MD and HG groups significantly decreased(all P＜0.05).Compared with the BG group,the positive expression of MMP-2 protein in the sclera of rats in the MG group increased(P＜0.001);compared with the MG group,the positive expression of MMP-2 protein in the sclera of rats in the WG,LG,MD and HG groups decreased(all P＜0.05).Under a transmission electron microscope,the scleral collagen fibers were arranged orderly and compactly with uniform size in rats of the BG group;compared with the BG group,scleral collagen fiber dissolution was found in the MG group;compared with the MG group,the scleral collagen fiber dissolution decreased and the density increased in the WG and LG groups.Com-pared with the MG group,the diameter of scleral collagen fibers was more uniform in the MD and HG groups with fewer in-terspaces and no fiber dissolution.Conclusion Yiqi Congming Decoction can regulate the expressions of MMP-2 and p-JNK in the sclera of LIM rats,and slow down the occurrence and development of myopia.

AIM:To explore the mechanism of PX-12 induced apoptosis of hepatocellular carcinoma cells.METHODS:Human hepatoma cell line Huh7 was se-lected as the main research object.After the cells were treated with thioredoxin inhibitor PX-12,the cell viability was detected by CCK8 method,the cell mi-gration ability was detected by cell scratch test,the cell proliferation ability was detected by cell prolif-eration kit,the levels of intracellular reactive oxygen species and apoptosis were detected by flow cy-tometry,and the expression of apoptosis-related proteins were detected by Western blot.RESULTS:Compared with the control group,the cell viability,migration ability and proliferation ability of PX-12 treatment group were significantly decreased(P＜0.05),and the level of intracellular reactive oxygen species was increased(P＜0.05)in a concentration-dependent manner.Apoptosis inhibitor Z-VAD-FMK and antioxidant NAC could restore the cell viability,and NAC could reduce the accumulation of intracel-lular reactive oxygen species induced by PX-12 and restore the apoptosis induced by PX-12(P＜0.05).CONCLUSION:PX-12 induces apoptosis of hepato-cellular carcinoma cells through oxidative stress.

OBJECTIVE: To explore the effect of auricular point pressure on anesthetic recovery in the patients undergoing laparoscopic cholecystectomy. METHODS: One hundred and forty patients undergoing laparoscopic cholecystectomy were randomized into a trial group (52 cases, 2 cases dropped out) and a control group (52 cases, 2 cases were eliminated). In the control group, the conventional anesthesia program and recovery intervention were adopted. In the trial group, on the basis of the regimen as the control group, the intervention of auricular point pressure was supplemented. The auricular points on the right side were selected, including sympathetic (AH_6a), brain (subcortex, AT₄), thalamus, exciting point, heart and sore center. One day before operation, the auricular point pressure started; and the auricular points were stimulated specially before anesthesia (T0), at the moment of operation ending (T1), when entering the recovery room, at the moment of the tube removal (T2) and in 10 min of the tube removal (T3), respectively; each auricular point was pressed for 1 min a time. The recovery time of spontaneous breathing, the time of eye opening, the removal time of endotracheal tube, the recovery time of orientation, and the time of exiting recovery room were compared between the two groups. The score of pain visual analogue scale (VAS) and that of Richmond agitation-sedation scale (RASS) at T2, T3 and when exiting recovery room (T4), and the relevant circulatory indexes (heart rate [HR], systolic blood pressure [SBP], diastolic blood pressure [DBP] and mean arterial pressure [MAP]) at T0, T1, T2 and T3 were observed in the two groups. RESULTS: In the trial group, the recovery time of spontaneous breathing, the time of eye opening, the removal time of endotracheal tube, the recovery time of orientation, the time of exiting recovery room were shorter than those of the control group (P<0.01, P<0.05). The pain VAS and RASS scores at T2, T3 and T4, as well as HR, SBP, DBP and MAP at T0, T1, T2 and T3 were not different statistically between the two groups (P>0.05). CONCLUSION Auricular point pressure can shorten the recovery time from anesthesia in the patients undergoing laparoscopic cholecystectomy.

Adipose progenitor cells(APCs) represent a prominent stromal cellular component of adipose tissue and are now identified as highly heterogenous populations. However, the role of APCs in regulating systemic metabolism remains unknown. Using single cell RNA-sequencing, we investigated the role of the APC subpopulations in regulating development of type 2 diabetes. CD9 + CD55 low APCs are the novel subset identified in this study, which is significantly increased in type 2 diabetic patients. Transplantation of these cells from type 2 diabetic patients into adipose tissue caused glycemic disturbance in mice. Depletion of pathogenic APCs improved obesity-related glycemic disturbance. Collectively, our data provide deeper insights into human APC functionality and highlights APCs as a potential therapeutic target to combat type 2 diabetes. This study has been published in Nature Communications, 2024, 15(1): 4827.

Objective:To explore the clinical effect of perforator pedicled propeller flap (PPPF) in reconstruction of soft tissue defect in ankle and foot, as well as the role of preoperative ultrasonography in assistance of the location of perforators in donor site.Methods:From January 2017 to June 2023, the Department of Microorthopedics of the Second Affiliated Hospital of Luohe Medical College of Higher Education applied PPPF to reconstruct small and medium-sized soft tissue defects in the ankle and foot for 26 patients. The patients were 17 males, 9 females, aged 18 to 68 years old with 46 years old in average. The defect sites were 3 in forefoot and 6 in midfoot and combined with different degrees of tendon and bone exposure, 17 in ankle and heel and combined with various degrees of bone exposure, 12 with ankle open injury and 5 with Achilles tendon exposure. The area of soft tissue defects ranged from 2.5 cm×1.5 cm to 16.0 cm × 6.5 cm. The width of injury was measured before surgery, and a HHD was used to detect the perforators proximal to the defect site, and then high-frequency CDU was used to locate and confirm the location of the perforator and its alignment, blood flow and diameter. The line drawn between the 2 perforators was set as the axis of flap. The donor site was assessed by a "pinching and lifting" method to determine a direct closure of donor site or to have it closed by a flap transfer. The sizes of flap were from 2.8 cm×1.5 cm to 24.0 cm×7.5 cm. Twenty-two donor sites were directly closed and 4 received flap transfers. Four flaps had sutures with the skin nerves in the recipient site. Masquelet technique was performed in 6 patients with bone defects in the surgery. Patients received outpatient reviews with 1-2 weeks of intervals in the first 2 months after surgery, and X-ray reviews per 1-2 months for those with bone implants until bone healing.Results:All flaps survived successfully without any special treatment after surgery, except 1 flap that had blood vessel congestion and showed swelling and poor blood supply to the distal flap at 24 hours after surgery. The blood vessel congestion was revised by removal of part of the suture at the tip of flap pedicle. One week later, the tip of the flap remained with a small area of necrosis, which was then healed after dressing changes. A total of 21 patients were included in postoperative follow-up with 4 months to 3 years. All of the flaps had satisfactory appearance, colour and texture, and without any ulceration. Three cases of nerve suture were also included in follow-up. According to the assessment criteria of British Medical Research Council (BMRC), the sensory recovery of the flaps was found of S 2 in 1 flap and S 3 in 2 flaps. According to the American Orthopaedic Foot and Ankle Society (AOFAS), the ankle-hindfoot function scores, there were excellent in 16 patient and good in 5 patients. Conclusion:With the assistance of ultrasound, the PPPF can be effectively used in reconstruction of soft tissue defects in ankle and foot.

Objective:To study the neurodevelopmental prognosis and risk factors for adverse outcomes of neonatal seizure.Methods:From December 2019 to November 2020, infants with neonatal seizure diagnosed in our hospital were enrolled in this retrospective study. Based on survival or not, mental development index (MDI), psychomotor development index (PDI) and seizure episodes at the age of 12 months, the infants were assigned into adverse outcome group and normal outcome group. The risk factors for adverse outcomes were statistically analyzed.Results:A total of 75 infants were enrolled,including 39 cases in adverse outcome group and 36 in normal outcome group. 69 cases showed abnormal amplitude-integrated electroencephalogram(aEEG), including 38 mildly abnormal cases,23 moderately abnormal cases and 8 severely abnormal cases, The incidences of adverse outcomes and mortality rates were significantly different ( P<0.05) among infants with different severity levels of aEEG abnormalities and the severity levels of aEEG abnormalities were positively correlated with adverse outcomes ( r=0.367, 0.471, P<0.05).Univariate analysis showed that adverse outcome group had significantly higher incidences of chorioamnionitis, seizure onset age ≤3 d, 5 min Apgar score ≤3, cranial ultrasound abnormalities, brain MR abnormalities and aEEG abnormalities than normal outcome group ( P<0.05).Logistic regression analysis showed that seizure onset age ≤3 d ( OR=3.988, 95% CI 1.376-11.674), abnormal brain MR ( OR=3.296, 95% CI 2.383-17.377) and bilirubin encephalopathy ( OR=3.792,95% CI 2.110-13.216) were independent risk factors for adverse outcomes of neonatal seizure. Conclusions:For neonatal seizure, the infants with more severe abnormal aEEG will have higher incidences of adverse outcomes and mortality. Seizure onset age ≤3 d, brain MR abnormalities and bilirubin encephalopathy were independent risk factors for adverse outcomes of neonatal seizure.
