Kui was first recorded in The Rites of Zhou and is the earliest domesticated wild vegetable in China. In the Qi Min Yao Shu, Kui was called “the master of all vegetables” and has a long history of application in China. As a medicine, Kuizi was first recorded in Shen Nong’s Herbal Classic, which has a history of more than 2 000 years of medicinal use and a long history of clinical application. By researching the ancient and modern herbal literature, the first herbs texts of Kui were examined, various recorded texts, confused products and the history of the original medicinal use were clarified. It was concluded that the ancient herbal texts recorded the base plant of Kui as Malva verticillata L. belonging to family Malvaceae, which provided scientific basis for the development and utilization of Kui.

Objective To explore the role of the brief visuospatial memory test-revised(BVMT-R)in predicting the clinical conversion to psychosis in subjects with clinical high-risk for psychosis(CHR-P).Methods A total of 217 CHR subjects were recruited and assessed using BVMT-R at baseline.Participants were followed up for three years to determine whether they converted to psychosis.The relationship between BVMT-R total score and CHR-P conversion probability was analyzed using generalized additive model,and the cutoff values of BVMT-R total score for predicting CHR-P conversion were calculated by maximally selected rank statistics.Then,the total BVMT-R score was stratified into different intervals based on the cutoff values obtained as previously described.Finally,the positive likelihood ratios and the conversion rates at different time points were calculated for each interval.Results A total of 168 subjects with CHR-P completed the 3-year follow-up assessment.According to the results of the generalized additive model,the relationship between the BVMT-R total score and CHR-P conversion probability exhibited the characteristics of a piecewise function model.The cutoff values identified using the maximally selected rank statistics method were 18 and 29,which divided the BVMT-R total scores into three intervals:0-18,19-29,and 30-36.The positive likelihood ratios of the three intervals for predicting CHR-P psychosis conversion were significantly different(all P<0.01).All three intervals had significantly different rates of psychosis conversion at different follow-up time points(all P<0.01).Conclusion The total BVMT-R score can be divided into three intervals,each associated with a distinct positive likelihood ratio for predicting psychosis conversion in CHR-P individuals.Accordingly,the BVMT-R total score may serve as a preliminary indicator for estimating the probability of psychosis conversion in the CHR-P population.

Aim To explore the mechanism by which the compound Chaijin Jieyu formula(CCJJY)regulates the TLR4/NLRP3 signaling pathway to inhibit central oxidative stress and improve hippocampal synaptic plasticity damage in depression.Methods SD rats were randomly divided into the control group,chronic unpredictable mild stress group,sleep deprivation group,chronic unpredictable mild stress combined with sleep deprivation group,positive drug group(venlafax-ine+melatonin),low-dose group of CCJJY,medium dose group of CCJJY,and high-dose group of CCJJY,with nine rats in each group.Except for the control group,a rat model of depression complicated with in-somnia was established using chronic unpredictable mild stress combined with sleep deprivation.Depres-sion-like and sleep behaviors in rats were evaluated through weight,food intake,water maze,and pento-barbital sodium tests.ELisa was used to detect ROS,AANAT,and HPLC-EC was used to detect 5-HT con-tent,while Western blot/RT-PCR was used to detect the expression of IL-1β,TLR4,NLRP3,PSD-95,and SYN related proteins and mRNA.HE and Golgic stai-ning were used to observe the pathological changes in the third ventricle,hippocampus,and neuronal synap-ses.Results Compared with the control group,the depression-like behaviors of the model group rats were significant.The expression of IL-1β,TLR4,and NL-RP3 in the hippocampus increased,while the expres-sion of PSD-95 and SYN decreased.Activation of NL-RP3 inflammasomes led to "sleeve like" pathological changes in the third ventricle,with hippocampal neu-rons undergoing apoptosis and significant damage to neuronal synaptic plasticity.Compared with the model group,after intervention with CCJJY,the expression of ROS,IL-1β,TLR4,and NLRP3 decreased,while the expression of AANAT,5-HT,PSD-95,and SYN in-creased.Pathological damage to the third ventricle and hippocampal neurons was repaired.Conclusion The CCJJY improves hippocampal synaptic plasticity dam-age in depression by regulating the TLR4/NLRP3 sig-naling pathway to inhibit central oxidative stress.

Objective To analyze the association between lifestyle and the risk of type 2 diabetes(T2D)among adult residents.Methods The data was sourced from the Shanghai Suburban Adult Cohort and Biobank.A total of 42 096 adult residents who had not developed T2D were recruited from four districts of Shanghai(Songjiang,Jiading,Minhang,and Xuhui)between 2016 and 2019.The follow-up ended on Feb 28,2023.A structured questionnaire was used to collect information on six lifestyle-related items,including smoking,alcohol consumption,BMI,waist circumference(WC),physical activity,and diet.The unhealthy lifestyle scores(UHLS)were calculated by counting the number of all the unhealthy lifestyle items,with a range of 0-6.New-onset T2D events diagnosed by physicians were obtained through the medical information system.Cox proportional hazards regression model and restricted cubic spline model were utilized to evaluate the association between unhealthy lifestyles and the risk of T2D incidence.Results About 28.1%of the participants led 4-6 unhealthy lifestyles.A total of 1 752 new T2D cases were identified during 218 513.4 person-years of follow-up.Analysis of single unhealthy lifestyle showed that abnormal WC(HR=1.5,95%CI:1.4-1.7)and abnormal BMI(HR=1.3,95%CI:1.2-1.5)were associated with an increased risk of T2D.Compared with individuals with a UHLS of 0-1,those with a UHLS of 3 and 4-6 had 30%(95%CI:1.1-1.6)and 50%(95%CI:1.2-1.8)higher risks of T2D,respectively.Each additional unhealthy lifestyle was associated with a 10%increase in T2D incidence risk(HR=1.1,95%CI:1.1-1.2).Conclusion The risk of T2D in adult residents increases with the cumulative number of unhealthy lifestyles.Adult residents with abnormal WC or BMI,or have three or more unhealthy lifestyles accumulated,will increase the risk of new-onset T2D.

Objective:To investigate the effects of wheat-grain moxibustion at the Guanyuan point on testosterone(T)synthe-sis and the hypothalamic-pituitary-gonadal(HPG)axis in naturally aged mice.Methods:We fed 40 twelve-month-old SPF male C57BL/6J mice with a normal diet for 3 months,randomized them into a moxibustion and an aged group of an equal number,and se-lected 7 four-month-old ones as young controls.We treated the animals of the moxibustion group by wheat-grain moxibustion at the Guanyuan point,once 5 moxibustion sticks,qd,5 times a week,and fed those of the aged group normally,all for 12 weeks.After treatment,we obtained the testicular index of the mice,observed the histomorphology of the testis tissue by HE staining,measured the contents of T in the testis,gonadotropin-releasing hormone(GnRH)in the hypothalamus and total T(tT),free T(fT),luteinizing hormone(LH)and follicle-stimulating hormone(FSH)in the serum by ELISA,and determined the expressions of silence information regulator-1(SIRT1),P53,glutathione peroxidase(GPX4)and cholesterol side-chain?cleavage enzym e(CYP11A1)in the testis by Western blot.Results:Compared with the young controls,the mice in the aged group showed obviously losing and dull hair,energy declination,loose structure of the spermatogenic tubule with different degrees of cell loss and rupture,reduced testicular index,and ev-ident aging phenotype.In comparison with the aged mice,the animals of the moxibustion group were fairly energetic and exhibited dis-tinct structure of the spermatogenic tubules,orderly arranged and highly differentiated cells at all levels,significantly increased T lev-el,up-regulated expressions of SIRT1,GPX4 and CYP11 A1,and down-regulated expression of P53 in testis tissue,and elevated levels of GnRH,FSH,LH,tT and fT in the HPG axis.Conclusion:Wheat-grain moxibustion at the Guanyuan point protects testosterone synthesis in the testis tissue of naturally aged mice,promotes negative feedback regulation of the HPG axis,and improves low testoster-one.

Objective:To explore the intervention effect of health nutrition model based on digital management on patients with gestational diabetes mellitus, and to provide reference for blood sugar control and pregnancy outcome improvement of gestational diabetes mellitus.Methods:Using a randomized controlled study method, totally 80 cases of gestational diabetes mellitus admitted to Langfang People's Hospital from October 2021 to March 2023 were prospectively selected and randomly divided into control group and experimental group according to the random number table method, with 40 cases in each group. The control group was given routine management, and the experimental group was combined with the health nutrition model based on digital management on this basis. Both groups began to intervene after the diagnosis of gestational diabetes mellitus, and the intervention lasted until one week before the patient's expected delivery. Follow-up to delivery. The delivery mode, weight gain during pregnancy, insulin use during pregnancy, pregnancy outcome and neonatal outcome of the two groups were statistically analyzed. The blood glucose level of the two groups before and after intervention were compared.Results:The age of the control group was 20-31 (26.25 ± 1.98) years old, while the age of the experimental group was 20-33 (25.93 ± 2.11) years old. The cesarean section rate in the experimental group was 32.50% (13/40), which was lower than that in the control group (57.50%, 23/40) ( χ2=5.05, P<0.05). The weight gain during pregnancy in the experimental group was (6.03 ± 0.89) kg, which was lower than (7.93 ± 1.36) kg in the control group ( t=7.39, P<0.05). After intervention, the levels of serum glycosylated hemoglobin, fasting blood glucose and 2 h postprandial blood glucose in the two groups were lower than those before intervention, and those in the experimental group were (5.19 ± 0.54) %, (4.98 ± 0.49) mmol/L, (6.04 ± 1.15) mmol/L, which were lower than (5.67 ± 0.75) %, (5.37 ± 0.54) mmol/L, (7.16 ± 1.36) mmol/L in the control group ( t=3.28, 3.42, 3.96, all P<0.05). The proportion of macrosomia in the experimental group was 2.50% (1/40), which was lower than 20.00% (8/40) in the control group ( χ2=4.51, P<0.05). The experimental group had no abnormal pregnancy outcome and neonatal outcome respectively as 92.50% (37/40) and 92.50% (37/40), which were 70.00% (28/40) and 57.50% (23/40) in the control group, their difference was statistically significant ( χ2=6.65, 13.07, both P<0.05). Conclusions:The application of health nutrition model based on digital management to intervene in patients with gestational diabetes could effectively improve their blood glucose control effect, improve pregnancy outcome and neonatal outcome, and hada good intervention effect.

Objective:To assess the level of moral distress among pediatric nurses in China and explore its influencing factors, providing a reference for future interventions.Methods:A cross-sectional survey was conducted using a convenience sampling method from May 2022 to March 2023. Pediatric nurses meeting the inclusion and exclusion criteria were selected from children′s specialized hospitals, general hospitals, and maternal and child health hospitals across 16 provinces in China. Moral distress was assessed using the Chinese version of the Moral Distress Scale-Revised (MDS-R). Data analysis included descriptive statistics, non-parametric analysis, and multiple linear regression.Results:A total of 509 pediatric nurses participated in the survey, including 10 males and 499 females. Among them, 45 were aged ≤25 years, 268 were aged 26-35 years, 172 were aged 36-45 years, and 24 were aged >45 years.The median moral distress score was 58.00 (26.00, 77.50). Factors independently associated with higher levels of moral distress included having a master′s degree ( t = 2.33), working in a ward with more than 40 beds ( t = 3.38), working in a ward without parental accompaniment ( t = 2.60), being passively assigned to the nursing profession ( t = 2.63), and considering resignation but not leaving the job ( t = 3.85) (all P<0.05). Conclusions:Pediatric nurses in China experience a moderate level of moral distress. Further research is needed to understand its underlying causes and to develop preventive and intervention strategies.

Objective To explore the correlation between the proximal angle of carotid atherosclerotic plaques and neovascularization scores,and their clinical application value in predicting recurrent cerebral infarction.Methods A total of 88 patients who underwent carotid plaque ultrasound examination in our hospital were selected.According to CT/MRI results,patients were divided into the non-cerebral infarction group(45 cases)and the cerebral infarction group(43 cases).Conventional ultrasound examination was performed followed by contrast-enhanced ultrasound.Plaque length,thickness and proximal angle were measured,and the neovascularization score of the proximal end was evaluated using contrast-enhanced ultrasound,and the results were compared and analyzed.Results In the cerebral infarction group,plaque thickness,proximal angle,and neovascularization score were significantly higher than those in the non-cerebral infarction group(P＜0.05),while there was no significant difference in plaque length.The proportion of plaques with a proximal neovascularization score of 2 or 3 was higher in the cerebral infarction group than those of the non-cerebral infarction group(79.1%vs.24.4%,P＜0.01).A positive correlation was found between the proximal angle and neovascularization score in all patients(rs=0.374,P＜0.01).There was no significant difference between the area under the ROC curve for neovascularization score in predicting recurrent cerebral infarction and the proximal angle(P＞0.05).The optimal cutoff value of the proximal angle was 18.8,and the sensitivity and the specificity for predicting recurrent cerebral infarction were 93.0%and 62.2%.In the cerebral infarction group,seven patients(16.3%)had recurrent infarction within one year,and these patients had higher proximal neovascularization scores,with angles greater than 18.8°.Conclusion There is a strong correlation between proximal angle of carotid plaques and neovascularization score,which has a positive predictive role in the recurrence of cerebral infarction,providing a reliable auxiliary diagnostic basis for clinical practice.
