ObjectiveBased on network pharmacology and transcriptomics， the mechanism of Zishen Qinggan prescription （ZSQGF） in improving glucose and lipid metabolism in type 2 diabetes （T2DM） model rats was explored. MethodBased on network pharmacology analysis of the differential genes between ZSQGF and T2DM， gene ontology（GO）analysis and Kyoto encyclopedia of genes and genomes（KEGG） analysis were conducted， and molecular docking analysis was used to verify the binding between components and targets. A T2DM rat model was established by high-fat feeding and injection of streptozotocin （STZ）. The rats were randomly divided into the control group， model group， metformin （Met， 72 mg·kg^-1） group， and ZSQGF high-， medium-， and low-dose groups （ZSQGF-H， ZSQGF-M， and ZSQGF-L， with 4.8， 2.4， and 1.2 g·kg^-1 raw drug in the solution）. The living status of rats was monitored and the levels of total cholesterol （TC）， total triglycerides （TG）， high density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， aspartate aminotransferase （AST）， and alanine aminotransferase （ALT） in rat serum were detected. The liver tissues were subjected to Hematoxylin eosin（HE） staining and oil red O staining. The differential genes were analyzed through transcriptomics， GO and KEGG analysis， and the protein-protein interaction（PPI） network was obtained to screen key targets. With network pharmacology and transcriptomics analysis results， the protein pathways were identified. The expression levels of nuclear factor-κB （NF-κB）， matrix metalloproteinase（MMP）-1 and MMP-9 proteins in liver tissues were detected by Western blot. The mRNA expression of B-cell lymphoma-2（Bcl-2） modifying factor（BMF）， nicotinamide adenine dinucleotide phosphate （NADPH） oxidase 4 （NOX4）， and fatty acid synthase（FASN） was detected by real-time polymerase chain reaction（Real-time PCR）. The expression of MMP-1 and MMP-9 in the liver was detected by immunofluorescence staining. ResultTranscriptomics and network pharmacology analysis suggested that ZSQGF may protect the liver through the glucose and lipid metabolism pathway and the inflammation pathway. Experiments showed that after 8 weeks of administration， the body weight， blood sugar， serum indicators， and pathological staining results of rats were improved. Western blot results indicated a decrease in the relative expression levels of NF-κB， MMP-1 and MMP-9 proteins in the liver. Real-time PCR results showed a decrease in the transcriptional expression of BMF， NOX4， and FASN in the ZSQGF-H group， while immunofluorescence staining results present decreased expression of MMP-1 and MMP-9 in the ZSQGF groups. ConclusionZSQGF can improve the glucose and lipid metabolism by inhibiting the expression of FASN， reducing lipid synthesis， and regulating the NF-κB signaling pathway.

ObjectiveTo evaluate the effectiveness and safety of Qiaoqi Formula （翘芪组方） for mild influenza. MethodsA randomized controlled study was designed， recruiting 74 patients with mild influenza， who were randomly divided into trial group and control group. The trial group took Qiaoqi Formula orally， 40ml each time， twice a day； the control group took Lianhua Qingwen Capsules （连花清瘟胶囊） orally， 1.4 g each time， three times a day. Both groups were treated for 3 consecutive days and follow-up for 4 consecutive days after treatment. The time for fever reduction including onset of fever reduction， complete fever reduction time， fever reduction rates at 24， 48 and 72 hours， improvement of influenza symptoms， total traditional Chinese medicine （TCM） symptom score， and safety indicators in two groups after treatment were recorded. ResultsSixty-five patients were ultimately included， including 36 in the trial group and 29 in the control group. Onset time of fever reduction in the trial group was （15.49±23.47） h， the complete fever reduction time （21.37±30.06）h， and the 24 h， 48 h， 72 h， fever reduction rate was 77.14%， 88.57%， 91.42% respectively. The above indicators of the control group showed as （17.58±20.38）h， （24.30±21.87）h， 61.29%， 90.32%， 96.77% respectively， with no statistically significant differences （P＞0.05）. On the 7th day after treatment， the total score of TCM syndromes in trial group and control group decreased compared to those before treatment （P＜0.05）. There was no statistically significant difference in the cure rate， significant effective rate， effective rate， and total effective rate of TCM syndromes between groups （P＞0.05）. On the 4th day， the lymphocyte ratio of patients in the control group was higher than before treatment， while alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， urea， and creatinine of both groups before and after treatment were within the normal range. The main adverse reactions in both groups were mild headache and dizziness， and no serious adverse reactions observed. ConclusionThe therapeutic effect of Qiaoqi Formula in treating mild influenza is equivalent to Lianhua Qingwen Capsules， which can shorten the fever reduction time， improve clinical symptoms， and no adverse events observed during the study.

Objective To explore the application value of echocardiography in the differential diagnosis of transthyretin cardiac amyloidosis(ATTR-CA)and immunoglobulin light chain cardiac amyloidosis(AL-CA).Methods We conducted a retrospective analysis of echocardiographic parameters of 50 confirmed CA patients diagnosed between November 2021 and January 2024 at The First Affiliated Hospital of Xi'an Jiaotong University,including 6 cases of ATTR and 44 cases of AL.Parameters that could potentially distinguish between the two subtypes were selected using t-tests and x2 tests,and the diagnostic capabilities of these parameters for the two subtypes were analyzed using receiver operating characteristic(ROC)curves.Results There were no statistically significant differences in general characteristics,global longitudinal strain(GLS),ratio of apical to basal strain,ejection fraction to GLS ratio(EFSR),maximum thickness of left ventricular myocardium,relative thickness of left ventricular wall,presence of thickened atrioventricular valves,or presence of enlarged atria between ATTR and AL groups(P＞0.05).The interventricular septal thickness was greater than in ATTR group than in AL group(P＜0.05),and the E/e'ratio(ratio of spectral Doppler early diastolic peak velocity to tissue Doppler early diastolic peak velocity)was greater in ATTR group than in AL group(P＜0.05).ROC curve analysis showed that the areas under the curve for distinguishing between the two subtypes based on interventricular septal thickness and E/e'ratio were 0.891(95％CI:0.792-0.991)and 0.826(95％CI:0.698-0.955),respectively,with a sensitivity of 100.00％and specificity of 95.24％for combined diagnosis.Conclusion Echocardiographic parameters,including E/e'ratio and interventricular septal thickness,may have clinical significance in distinguishing between the two main subtypes of CA in patients.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

Objective:This study aims to obtain the prevalence and features associated with Violence Against Children (VAC) in China and, thus, formulate a prevention strategy.Methods:The mortality-related data of VAC was sourced from the National Disease Surveillance Points System (DSP) during 2013-2021. We analyzed the DSP data regarding children aged 0-17 years old who died from violence. The hospital cases of VAC was sourced from the National Injury Surveillance System (NISS), 2013-2021. We analyzed the data from NISS with the parameter of "intentional injury" caused by VAC in children aged between 0-17 years. Using robust linear regression, we analyze the time trend in the proportion of violence incidence. To understand the variations in the incidence of different types of violence across genders, we apply the chi-square test and adjusted Pearson residuals.Results:The overall trend of death caused by VAC has declined; it was reduced to 0.14/100 000 in 2021 from 0.33/100 000 in 2013. In 2021, male VAC mortality (0.15/100 000) was higher than females (0.13/100 000). The proportion of VAC cases to all injury cases has declined from 3.34% in 2013 to 2.29% in 2021. Among 9 344 VAC cases supervised by hospitals in 2021, the number of males (7 503 cases) was around 4 times that of females (1 841 cases), and the top three modes of violence were blunt tools (64.77%), falls (7.46%) and sharp instruments (6.18%), and 45 cases of sexual violence included 38 girls and 7 boys.Conclusions:The declining death rate due to VAC may be related to the benign development of Chinese society. Prevention strategies targeting training in parenting skills and problem-solving should be prioritized.

Objective:To explore the clinical manifestations of two fetuses harboring heterozygous deletions of the SHOX gene. Methods:Two pregnant women who had presented at the Prenatal Diagnosis Center of Nanjing Drum Tower Hospital respectively on June 24, 2022 and July 27, 2022 were selected as the study subjects. In case 1, prenatal ultrasonography had shown short femur and intrauterine growth retardation of the fetus. Case 2 had a history of spontaneous abortions due to structural chromosomal aberrations. Fetus 1 had undergone a test for the FGFR3 gene, and both fetuses were subjected to single nucleotide polymorphism-based microarray (SNP array) analysis. Results:Affter excluding the influence of FGFR3 gene Fetus 1 was found to harbor a heterozygous 883 kb deletion at Xpter or Ypter, whilst fetus 2 was found to harbor a 5.75 Mb deletion in the Xpter region. Both deletions have encompassed the SHOX gene. The origin of the deletion in fetus 1 was unknown, whilst that in fetus 2 was inherited from its mother. Fetus 1 has been delivered at term with a normal phenotype, and fetus 2 was not born yet. Conclusion:The intrauterine and postnatal phenotypes of fetuses may be predicted by combining the ultrasound finding, parental phenotype and results of CMA, variant, and the results can facilitate genetic counseling and decision making over the pregnancy.

Objective:To explore the genetic characteristics of three fetuses with regions of homozygosity (ROH).Methods:Three fetuses with ROH diagnosed at Nanjing Drum Tower Hospital on December 2, 2020, March 19, 2021, and May 27, 2022, respectively were selected as the study subjects. Clinical data of the fetuses were collected. Chromosomal microarray analysis (CMA) was used to detect the ROH, and tandem repeat sequences (STR)-based multiplex PCR assay was used to identify the mosaicism status in fetus 1.Results:Partial maternal isodisomy (iUPD) (16) was found in fetus 1, for which trisomy rescue may be accountable. Meanwhile, the fetus also has confined placental mosaicism (CPM) but not true mosaicism. The formation mechanism of ROH for fetus 2 was identity by descent. Partial maternal iUPD (7) was found in fetus 3, which may be due to gametic recombination.Conclusion:The ROH of the three fetuses were inherited from both parents or the mother. Above findings suggested that it is justified to detect ROH on imprinting disorder-related chromosomes when potential uniparental disomy is suspected.

Objective:To explore the correlation between structural chromosomal abnormality and clinical characteristics of a child featuring gonadal dysplasia.Methods:A 13-year-old child who was admitted to Lianyungang Maternal and Child Health Care Hospital on February 7, 2023 for primary amenorrhoea and occasional abdominal pain was selected as the study subject. Clinical data of the child was collected, and peripheral blood samples of the child and her parents were collected. G-banding chromosomal karyotyping and copy number variation sequencing (CNV-seq) were carried out. "Pseudodual centromere isochromosome X" and "psu idic(X)" were used as keywords to search the CNKI, Wanfang and PubMed databases, and the search period was set as from January 1, 2002 to June 1, 2023. Relevant literature on the structural abnormality of X chromosome was searched and analyzed retrospectively.Results:The child has a height of 153 cm and weighed 45 kg. She has no obvious facial dysmorphism. Laboratory tests showed that she had higher FSH and luteinizing hormone, and lower E2. Ultrasonography showed that she had small ovaries and rudimentary uterus. She was found to have a karyotype of 46, X, psu idic(X)(q21.3)[40]/mos 45, X[3], whilst both of her parents had a normal karyotype. CNV-seq showed that she had a 63.27 Mb deletion in Xq21.32q28 and a 91.59 Mb duplication in Xp22.33q21.32 (mosaicism rate = 74%). A total of 11 relevant literature were retrieved. Clinical phenotypes of patients with similar structural chromosomal abnormalities were diverse, which was closely related to the mosaicism rate of the 45, X karyotype and the location of the breaking point.Conclusion:46, X, psu idic(X)(q21.3)/45, X probably underlay the dysplasia of uterus and ovary and sex hormone abnormalities in this child, while her height was spared. Deletion of Xq21.32q28 is a key factor leading to Turner syndrome-like phenotype such as rudimentary uterus and ovarian dysplasia.

Objective To explore the predictive effect of empowerment and theory of planned behavior(TPB)on the four core behaviors of type 2 diabetes mellitus(T2DM)self-management,and analyze the influence path of TPB model and behavioral intention on the four core behaviors.Methods A total of 500 T2DM patients who were hospitalized in the Endocrinology Department of three tertiary general hospitals in different provinces from December 2022 to May 2023 were selected for investigation.Hierarchical multiple regression analysis was used to explore the predictive effects of empowerment and TPB models on self-management behaviors.Bootstrap method was used to analyze the influence path of TPB model and behavior intention on self-management behaviors.Results Empowerment had a predictive effect on self-management behavior,which was improved after the addition of TPB,with medication R2=0.194,blood glucose monitoring R2=0.308,regular diet R2=0.337 and regular exercise R2=0.343,respectively.Mediation effect analyses revealed that attitude,subjective norm,and perceived behavioral control were observed to predict behavior intention across the four behaviors,and the three except through the behavior intention indirectly affect behavior,can also directly affect the behavior.Conclusions Empowerment can predict self-management behavior,and adding TPB to this can improve the prediction effect.Attitude,subjective norms and perceived control can indirectly or directly affect self-management behavior through behavioral intention.

Purpose To investigate the difference of cerebral blood flow between sleep deprivation and rest wakefulness.Materials and Methods Fifty subjects were recruited from universities in Xi'an from October 2020 to December 2021.The psychomotor vigilance test(PVT)task was used to measure sustained attention.Arterial spin labeling technique was used to analyze and compare the relative cerebral blood flow(rCBF)between sleep deprivation and rest wakefulness.The correlation between altered rCBF of specific brain regions and PVT task performance after sleep deprivation was analyzed.Results Compared with rest wakefulness,rCBF in bilateral dorsolateral prefrontal lobe,bilateral parietal lobule,left orbital middle frontal gyrus,bilateral middle temporal gyrus,right posterior central gyrus,and bilateral angular gyrus was significantly decreased after sleep deprivation.The rCBF of bilateral thalamus,left precuneus,right medial prefrontal lobe,left posterior cingulate gyrus,and left inferior temporal gyrus was significantly increased(FDR corrected,P<0.05,cluster size≥20 voxels).The changes of rCBF in left dorsolateral prefrontal lobe and right parietal lobule were significantly negatively correlated with the PVT task performance(r=-0.56,P<0.001;r=-0.64,P<0.001),and the change of rCBF of left precuneus was significantly positively correlated with the PVT task performance(r=0.72,P<0.001).Conclusion The abnormal changes of CBF in default mode network,frontoparietal network-related brain regions and thalamic may be the important neural mechanism of sustained attentional decline after sleep deprivation.
