Objective To design and test the reliability and validity of patient admission nursing assessment sheet of integrated Chinese and westem medicine ward.Methods On the basis of literature research,with traditional Chinese medicine"look,hear,ask and pulse-taking"as the basic framework,physical discrimination as the evaluation outcome,combined with the general nursing evaluation points of patients admitted to hospital,we designed the patient admission nursing assessment sheet of integrated Chinese and westem medicine ward,and then we adopted the Delphi method to conduct an inquiry on the draft of the admission sheet.In April 2022,3 clinical nurses were selected to evaluate 160 admitted patients from Integrated Traditional Chinese and Western Medicine Department of a tertiary A comprehensive hospital in Hubei Province,and Fleiss'Kappa coefficient and content validity coefficient were used to test the reliability and validity.Results The recovery rates of the 2 rounds of expert correspondence questionnaires were 95.45％and 100％.The authority coefficients were 0.931 and 0.957;the Kendall harmony coefficients were 0.101 and 0.106(P＜0.01);the importance scores of articles were 4.13～4.82;the coefficient of variation was 0.07～0.19 in 2nd round of expert correspondence.The final nursing assessment list for inpatients in the integrated Chinese and Western medicine ward included 3 parts:general demographic data assessment,four-Chinese medicine diagnosis assessment/physical discrimination,and nursing risk assessment,and there are 32 evaluation contents in the assessment sheet.The Fleiss'Kappa coefficient of this assessment sheet was 0.602(P＜0.001);the item content validity index was 0.857～1.000,and the overall content validity index was 0.920.Conclusion The admission nursing assessment sheet for inpatients in integrated Chinese and Westem medicine wards has good reliability and validity,and it is suitable for the integrated Chinese and Westem medicine wards.

AIM:To explore the molecular mechanism by which leukemia inhibitory factor(LIF)enhances the stemness characteristics of colorectal cancer(CRC)cells by regulating the expression of the molecular marker CD44 in cancer stem cells(CSCs).METHODS:The expression of LIF in CRC tissues was analyzed using the TCGA public data-base and RNAscope in situ hybridization method.Stable knockdown of LIF was constructed in CRC cell lines(HCT116 and Caco2 cells)using a lentiviral infection system.The experiment was divided into 4 groups:CRC cells control group,CRC cells plus LIF group,CRC cells knockdown control group,and CRC cells knockdown LIF group.The impact of exog-enous LIF on CRC cells' capacity for spheroidization was assessed through stem cell spheroidization assays.The ability of CRC cells to proliferate and migrate was evaluated using MTT,RTCA,plate cloning,and migration tests following the ad-dition or removal of LIF.The impact of LIF on the expression of the transcription factor ELF3 and CD44 in CRC tumor cells was determined using RT-qPCR,a fully automated protein expression analysis system,and Western blot.RT-qPCR was used to identify changes in CD44 splicing variant expression following LIF knockdown.RESULTS:The results dem-onstrated that the expression level of LIF in CRC tissue was higher than that in neighboring cancer tissue(P<0.01),and that patients with CRC who had high expression of LIF had a shorter disease-free survival time(P<0.05).While LIF knockdown can decrease CRC cells' capability to proliferate and migrate(P<0.05),exogenous LIF can boost CRC cells' sphericity,proliferation,and migration capacity(P<0.05).Exogenous LIF can raise(P<0.05)CD44 expression in CRC tumor cells,however LIF reduction can lower(P<0.01)CD44 expression and lower the transcription level of CD44 splic-ing variants.Exogenous injection of LIF or LIF knockdown can cause a significant change(P<0.05)in the expression lev-el of the transcription factor ELF3.CONCLUSION:LIF improves the stemness characteristics of colorectal cancer cells by upregulating the transcription factor ELF3,which also promotes the development of malignancy by increasing CD44 ex-pression in CRC cells.

Further evidence is needed to explore the impact of high-altitude environments on the neurologic function of neonates.Non-invasive techniques such as cerebral near-infrared spectroscopy and amplitude-integrated electroencephalography can provide data on cerebral oxygenation and brain electrical activity.This study will conduct multiple cerebral near-infrared spectroscopy and amplitude-integrated electroencephalography monitoring sessions at various time points within the first 3 days postpartum for healthy full-term neonates at different altitudes.The obtained data on cerebral oxygenation and brain electrical activity will be compared between different altitudes,and corresponding reference ranges will be established.The study involves 6 participating centers in the Chinese High Altitude Neonatal Medicine Alliance,with altitude gradients divided into 4 categories:800 m,1 900 m,2 400 m,and 3 500 m,with an anticipated sample size of 170 neonates per altitude gradient.This multicenter prospective cohort study aims to provide evidence supporting the impact of high-altitude environments on early brain function and metabolism in neonates.[Chinese Journal of Contemporary Pediatrics,2024,26(4):403-409]

Objective To evaluate the value of rs61330082 and rs4730153 polymorphisms of Visfatin locus for the diagnosis of type 2 diabetes mellitus(T2DM)in a high-risk population.Methods SNPscanTM high-throughput single nucleotide polymorphism typing technique was used to genotype Visfatin gene loci rs61330082 and rs4730153 in 346 T2DM patients(T2DM group)and 1426 normal controls(NC group).Logistic regression analysis was used to analyze T2DM risk factors.ROC curves were used to analyze the optimal cut-off values of Visfatin gene rs61330082 and rs4730153 for the diagnosis of T2DM.Results The proportion of women,age,obesity,smoking,hypertension,FPG,HbA1c and TG were higher in T2DM group than those in NC group(P<0.01)and HDL-C was lower than in NC group(P<0.01).The frequency of G allele and GG genotype was higher in T2DM group compared with NC group(P<0.05).Logistic regression analysis showed that age,female,obesity,hypertension,TG,and GG genotype at rs4730153 locus were risk factors for T2DM,HDL-C was a protective factor for T2DM.The area under the ROC curve of GG genotype at Visfatin rs4730153 mutation for diagnosis of T2DM was 0.668 and the optimal cut-off point for predicting T2DM was 20.04%,with sensitivity 60.1%and specificity 66.1%,respectively.Conclusion The GG genotype of Visfatin gene rs4730153 locus is associated with the risk of T2DM and can beused as a candidate gene for predicting phenotype of T2DM.

In this study, an established ultra-high performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) method was combined with multivariate statistical analysis to investigate the commonality and difference of main chemical components in the medicinal parts of Paeonia lactiflora from different cultivars; in addition, a high performance liquid chromatography(HPLC) method was established to simultaneously determine the content of eight active components in Paeoniae Radix Alba. Non-targeted analysis was carried out by UPLC-Q-TOF-MS on a Waters ACQUITY UPLC BEH C_(18)(2.1 mm×100 mm, 1.7 μm) column with a gradient elution of 0.1% aqueous formic acid(A)-acetonitrile(B) as the mobile phase at a flow rate of 0.2 mL·min~(-1). The column temperature was 30 ℃, and an electrospray ionization source was used to acquire mass spectrometry data in positive and negative ion modes. According to the accurate molecular weight and fragment ion information provided by multi-stage mass spectrometry and by comparison with reference substances and literature reports, thirty-six identical components were identified in Paeoniae Radix Alba from different cultivars with positive and negative ion modes. In the negative ion mode, two groups of samples were well separated; specifically, seventeen components with significant differences in content were screened and identified, and one component unique in "Bobaishao" was obtained. Quantitative analysis was conducted by high-performance liquid chromatography(HPLC) on an Agilent HC-C_(18)(4.6 mm×250 mm, 5 μm) column with a gradient elution of 0.1% aqueous phosphoric acid(A)-acetonitrile(B) as the mobile phase at a flow rate of 1.0 mL·min~(-1). The column temperature was 30 ℃ and the detection wavelength was at 230 nm. An HPLC method was developed for the simultaneous determination of eight active components(gallic acid, oxypaeoniflorin, catechin, albiflorin, paeoniflorin, galloylpaeoniflorin, 1,2,3,4,6-O-pentagalloylglucose, benzoyl-paeoniflorin) in Paeoniae Radix Albaa from different cultivars. Satisfactory linearity was achieved within the investigated linear ranges and with fine coefficients(r>0.999 0), and the methodological investigation showed that the method had good precision, repeatability and stability. The mean recoveries were 90.61% to 101.7% with RSD of 0.12% to 3.6%(n=6). UPLC-Q-OF-MS provided a rapid and efficient qualitative analytical method for the identification of the chemical components in Paeoniae Radix Alba, and the developed HPLC method was simple, rapid and accurate, which could provide a scientific basis for the evaluation of the germplasm resources and herbal quality of Paeoniae Radix Alba from different cultivars.

Background::At present, a large number of chronic obstructive pulmonary disease (COPD) patients are undiagnosed in China. Thus, this study aimed to develop a simple prediction model as a screening tool to identify patients at risk for COPD.Methods::The study was based on the data of 22,943 subjects aged 30 to 79 years and enrolled in the second resurvey of China Kadoorie Biobank during 2012 and 2013 in China. We stepwisely selected the predictors using logistic regression model. Then we tested the model validity through P-P graph, area under the receiver operating characteristic curve (AUROC), ten-fold cross validation and an external validation in a sample of 3492 individuals from the Enjoying Breathing Program in China.Results::The final prediction model involved 14 independent variables, including age, sex, location (urban/rural), region, educational background, smoking status, smoking amount (pack-years), years of exposure to air pollution by cooking fuel, family history of COPD, history of tuberculosis, body mass index, shortness of breath, sputum and wheeze. The model showed an area under curve (AUC) of 0.72 (95% confidence interval [CI]: 0.72-0.73) for detecting undiagnosed COPD patients, with the cutoff of predicted probability of COPD=0.22, presenting a sensitivity of 70.13% and a specificity of 62.25%. The AUROC value for screening undiagnosed patients with clinically significant COPD was 0.68 (95% CI: 0.66-0.69). Moreover, the ten-fold cross validation reported an AUC of 0.72 (95% CI: 0.71-0.73), and the external validation presented an AUC of 0.69 (95% CI: 0.68-0.71).Conclusion::This prediction model can serve as a first-stage screening tool for undiagnosed COPD patients in primary care settings.

Abstract: Objective　To evaluate the potential transmission risk of schistosomiasis in Yunnan Province, and to provide strategic basis for the prevention and control. Methods　Based on the prevalence of schistosomiasis, the social and environmental factors that may lead to the epidemic, 1-3 villages from 3 provincial-level and 15 county-level counties (cities and districts) were selected as the evaluated villages in 2021. The risk of schistosomiasis spread was analyzed comprehensively by consulting, reviewing and collecting routine surveillance data of schistosomiasis in the villages, combined with snail and wild feces survey. The risk level was evaluated for the positive snails, positive wild feces, resident infection, average density of live snails and snail frame occurrence rate. Results　Totally 7 snail counties schistosomiasis transmission was blocked of 18 epidemic counties and the rest were eliminated counties. A total of 152 447 snail frames were investigated and 3 043 frames with snails, 15 895 snails were captured and included 15 727 live snails in the 32 evaluated villages. The total area of snail was 58.87 hm2 and the area of reoccurrence was 34.19 hm2 with snail frame occurrence rate of 2.00% and average density of live snails 0.103 2/0.11 m2, and no positive snails were found by loop-mediated isothermal amplification (LAMP) assay. A total of 1 374 wild feces were collected in 27 evaluated villages of 14 epidemic counties, mainly from cattle, dogs, sheep, equine animals, pigs and so on, all of which were negative. According to the risk assessment of epidemic spread, Yongle Village and Yongsheng Village in Eryuan County, Zhiming Village in Chuxiong City were Ⅱ risk, and the rest were Ⅲ risk. Conclusions　Although the risk of transmission is low in Yunnan Province, the risk of transmission and spread still exists. It is necessary to strengthen the risk monitoring, control of snail and effective management of livestock to prevent the rebound of the epidemic.

Objective To compare the functional status of diabetic patients with and without nephropathy and identify the items that diabetic patients with nephropathy are more likely to develop dysfunction than diabetic patients without nephropathy based on the international classification of functioning,disability and health rehabilitation set(ICF-RS).Methods A cross-sectional study was conducted.A total of 320 diabetic patients hospitalized in Guangdong Provincial Hospital of Chinese Medicine from August 2021 to February 2022 were selected and assigned into a group with nephropathy and a group without nephropathy.The general characteristics,clinical examination,and laboratory findings were compared by the t test,rank sum test,and Chi-squared test.The functional status of the patients was compared between the two groups by the t test based on the ICF-RS.Logistic regression was employed to control interferential factors between the two groups and identify the association between nephropathy and ICF-RS problematic items among diabetic patients.Results The diabetic patients with nephropathy had more problematic items in ICF-RS(P<0.001),the body function dimension(P=0.003),the activity dimension(P<0.001),and the participation dimension(P<0.001)than those without nephropathy.Moreover,the diabetic patients with nephropathy experienced severer problems in 5 body function items(energy and drive functions,sleep functions,sexual functions,exercise tolerance functions,and muscle power functions),10 activity items(transferring oneself,walking,moving around using equipment,moving around,washing oneself,caring for body parts,toileting,dressing,doing housework,and looking after one's health),and 4 participation items(using transportation,assisting others,basic interpersonal interactions,and recreation and leisure)(all P<0.05).The Logistic regression results showed that compared with the diabetic patients without nephropathy,the diabetic patients with nephropathy were more likely to develop problems in energy and drive functions(aOR=4.35,95%CI=1.28-14.79,P=0.019),emotional functions(aOR=1.88,95%CI=1.06-3.34,P=0.031),sexual functions(aOR=3.39,95%CI=1.82-6.34,P<0.001),moving around(aOR=3.11,95%CI=1.76-5.52,P<0.001),doing housework(aOR=17.48,95%CI=3.57-85.60,P<0.001),looking after one's health(aOR=1.97,95%CI=1.13-3.43,P=0.017),using transportation(aOR=2.59,95%CI=1.38-4.88,P=0.003),and recreation and leisure(aOR=2.52,95%CI=1.46-4.35,P<0.001).Conclusion Compared with the diabetic patients without nephropathy,the patients with nephropathy suffer more ICF-RS problematic items and are more likely to develop dysfunction in certain items in all the three dimensions.

Objective: To investigate the relationship between body mass index (BMI) and sexual development in Chinese children. Methods: A nationwide multicenter and population-based large cross-sectional study was conducted in 13 provinces, autonomous regions and municipalities of China from January 2017 to December 2018. Data on sex, age, height, weight were collected, BMI was calculated and sexual characteristics were analyzed. The subjects were divided into four groups based on age, including ages 3-<6 years, 6-<10 years, 10-<15 years and 15-<18 years. Multiple Logistic regression models were used for evaluating the associations of BMI with sexual development in children. Dichotomous Logistic regression was used to compare the differences in the distribution of early and non-early puberty among normal weight, overweight and obese groups. Curves were drawn to analyze the relationship between the percentage of early puberty and BMI distribution in girls and boys at different Tanner stages. Results: A total of 208 179 healthy children (96 471 girls and 111 708 boys) were enrolled in this study. The OR values of B2, B3 and B4+ in overweight girls were 1.72 (95%CI: 1.56-1.89), 3.19 (95%CI: 2.86-3.57), 7.14 (95%CI: 6.33-8.05) and in obese girls were 2.05 (95%CI: 1.88-2.24), 4.98 (95%CI: 4.49-5.53), 11.21 (95%CI: 9.98-12.59), respectively; while the OR values of G2, G3, G4+ in overweight boys were 1.27 (95%CI: 1.17-1.38), 1.52 (95%CI: 1.36-1.70), 1.88 (95%CI: 1.66-2.14) and in obese boys were 1.27 (95%CI: 1.17-1.37), 1.59 (95%CI: 1.43-1.78), and 1.93 (95%CI: 1.70-2.18) (compared with normal weight Tanner 1 group,all P<0.01). Analysis in different age groups found that OR values of obese girls at B2 stage and boys at G2 stage were 2.02 (95%CI: 1.06-3.86) and 2.32 (95%CI:1.05-5.12) in preschool children aged 3-<6 years, respectively (both P<0.05). And in the age group of 6-10 years, overweight girls had a 5.45-fold risk and obese girls had a 12.54-fold risk of B3 stage compared to girls with normal BMI. Compared with normal weight children, the risk of early puberty was 2.67 times higher in overweight girls, 3.63 times higher in obese girls, and 1.22 times higher in overweight boys, 1.35 times higher in obese boys (all P<0.01). Among the children at each Tanner stages, the percentage of early puberty increased with the increase of BMI, from 5.7% (80/1 397), 16.1% (48/299), 13.8% (27/195) to 25.7% (198/769), 65.1% (209/321), 65.4% (157/240) in girls aged 8-<9, 10-<11 and 11-<12 years, and 6.6% (34/513), 18.7% (51/273), 21.6% (57/264) to 13.3% (96/722), 46.4% (140/302), 47.5% (105/221) in boys aged 9-<10, 12-<13 and 13-<14 years, respectively. Conclusions: BMI is positively correlated with sexual development in both Chinese boys and girls, and the correlation is stronger in girls. Obesity is a risk factor for precocious puberty in preschool children aged 3-<6 years, and 6-<10 years of age is a high risk period for early development in obese girls.

Objective To investigate the morphological variation of Oncomelania hupensis shells in Yunnan Province, so as to provide insights into the understanding of O. hupensis genetic evolution and control. Methods According to the O. hupensis density, geographical location, altitude, water system and environmental type, 12 administrative villages were sampled from 10 schistosomiasis-endemic counties (districts) in 3 prefectures (cities) of Yunnan Province as snail collection sites. From December 2021 to January 2022, about 200 snails were collected from each collection site, among which thirty adult snails (6 to 7 spirals) were randomly selected from each site, and the 11 morphological indexes of snail shells were measured and subjected to cluster analysis and principal component analysis. Results Of O. hupensis snails from 12 localities of Yunnan Province, the longest shell (7.33 mm) was detected in snails from Yongle Village, Eryuan County, with the shortest (4.68 mm) in Dongyuan Village, Gucheng District, and the largest angle of apex (59.47°) was measured in snails from Caizhuang Village, Midu County, with the smallest (41.40°) in Qiandian Village, Eryuan County. The mean coefficient of variation was 9.075% among O. hupensis snails from 12 localities of Yunnan Province, with the largest coefficient of variation seen in the thickness of the labra brim (29.809%). Among O. hupensis snails from 12 localities of Yunnan Province, the mean Euclidean distance was 2.26, with the shortest Euclidean distance seen between O. hupensis snails from Qiandian Village of Eryuan County and Wuxing Village of Dali City (0.26), and the largest found between O. hupensis snails from Caizhuang Village of Midu County and Cangling Village of Chuxiong County (8.17). Cluster analysis and principal component analysis classified O. hupensis snails from 12 localities of Yunnan Province into three categories, including the O. hupensis snail samples from Caizhuang Village of Midu County, O. hupensis snail samples from Cangling Village of Chuxiong County, and O. hupensis snail samples from Qiandian Village of Eryuan County, Wuxing Village of Dali City, Yangwu Village of Yongsheng County, Xiaoqiao Village of Xiangyun County, Yongle Village of Eryuan County, Xiaocen Village of Dali City, Anding Village of Nanjian County, Dongyuan Village of Gucheng District, Lianyi Village of Heqing County, and Dianzhong Village of Weishan County. The variations in these three categories of snail samples were mainly measured in the principal component 2 related to the angle of apex and the thickness of the labra brim. Conclusions The variations in the Euclidean distance and morphological features of shells of O. hupensis from 12 localities of Yunnan Province gradually rise with the decrease in the latitude of the collection sites. The angle of apex is an indicator for the growth of O. hupensis whorl.
