ObjectiveTo identify the active constituents of Kaixuan Jiedu core prescription （KXJD） and investigate its effective components and therapeutic targets in the treatment of common psoriasis. MethodsUltra-performance liquid chromatography-high resolution mass spectrometry （UPLC-Q-TOF MS） was used to identify and analyze the chemical components of KXJD and its blood-entering chemical components. The chemical components of the single decoction were further identified to clarify the source of the chemical components in KXJD. Then， all identified blood-entering compounds were screened for effective active ingredients through the Swiss ADME database. The active ingredient targets of KXJD were searched on the Swiss Target Prediction platform. The targets of common psoriasis were searched in OMIM， GEO， GeneCards， and DISGNET databases to obtain drug-disease intersection targets. The protein-protein interaction network of intersection targets was constructed using STRING， and then the core blood-entering component-intersection target network of KXJD was constructed. The core target proteins in the network were selected for molecular docking with the core components of KXJD. Small molecules and proteins were pretreated， and appropriate docking sites were selected. AutoDock Vina software was used for continuous local search and repeated iterations to find molecular docking conformations. PyMOL software and LigPlot+ software were used for analysis and visualization. Subsequently， the verification was carried out through animal experiments. SPF-grade male C57 mice were randomly divided into a blank group， a model group， a positive drug methotrexate group， and a KXJD group. In the model group， the methotrexate group， and the KXJD group， imiquimod was applied to the backs of the mice for modeling. The blank group and the model group were administered normal saline by gavage， while the methotrexate group and the KXJD group were respectively administered 1 mg·kg^-1 suspension and 30.42 g·kg^-1 decoction of traditional Chinese medicine by gavage. Five days after administration， the mice were sacrificed， and samples were collected. Hematoxylin-eosin （HE） staining was used to observe the skin tissue samples of mice， and the effect of KXJD on the pathological manifestations of psoriasis mice was analyzed. The expression areas of tumor necrosis factor-α （TNF-α）， cyclooxygenase 2 （PTGS2）， interleukin （IL）-1β， and IL-6 in the skin tissue of mice were detected by immunohistochemistry （IHC）. The mRNA expressions of TNF-α， IL-1β， IL-6， and PTGS2 in the skin tissue of mice were detected by real-time fluorescent quantitative polymerase chain reaction （Real-time PCR）. ResultsIn this study， 208 compounds in KXJD were identified by UPLC-Q-TOF MS， and 44 compounds were detected in serum， including 28 prototype components and 16 metabolites. 12 blood-entering active components were screened， and 1 153 active component targets and 1 076 psoriasis-related targets were identified. Eighty-five targets in the intersection set were drug-disease common targets. PPI network analysis showed that TNF-α， IL-1β， IL-6， PTGS2， and ALB were the key target proteins. The results of molecular docking showed that the binding ability of （+）-hexylphenylglycolic acid to key target proteins such as PTGS2 was stable， and PTGS2 showed high stability with a variety of core compounds. Compared with those in the blank group， the stratum corneum and epidermis in the model group mice were significantly thickened， and the pathological Baker score of the mice's skin in the model group was significantly higher than that of the blank group （P<0.01）. The expression areas of PTGS2， TNF-α， IL-1β， and IL-6 proteins in the skin tissue of the model group mice were significantly increased （P<0.01）， and the expression levels of PTGS2， TNF-α， IL-1β， and IL-6 mRNA in the skin tissue of the model group mice were significantly elevated （P<0.01）. Compared with the model group， the pathological Baker scores of the methotrexate group and the KXJD group were both decreased （P<0.01）， and the expression areas in the skin tissue of the methotrexate group and the KXJD group were significantly reduced （P<0.05， P<0.01）. The expression levels of PTGS2， TNF-α， IL-1β， and IL-6 mRNA in the skin tissue of the methotrexate group and the KXJD group were significantly decreased （P<0.01）. ConclusionKXJD can effectively improve the skin lesions of psoriasis model mice and reduce the expression of TNF-α， IL-1β， IL-6， and PTGS2 in the skin tissue of psoriasis model mice. PTGS2 has a stable binding ability with a variety of compounds in the decoction， which may be a key target for the treatment of psoriasis. The compound （+）-hexylphenylglycolic acid may play a key role.

Objective:To gain a deeper understanding of the cognitive differences between lactating women and obstetric nurses regarding their breastfeeding counselling abilities.Methods:This study was a descriptive phenomenology qualitative study. From October 2021 to June 2022, purposive sampling was used to select 11 lactating women who received breastfeeding counselling and 13 obstetric nurses who provided breastfeeding counselling services in Department of Obstetrics at Peking Union Medical College Hospital for semi-structured interviews. Giorgi analysis method was used to extract and analyze data.Results:The cognitive differences between lactating women and obstetric nurses regarding breastfeeding counselling abilities were mainly manifested in four aspects, namely breastfeeding knowledge and skills, counselling practice ability, improving counselling ability, and personality traits.Conclusions:Lactating women and obstetric nurses have cognitive differences in breastfeeding counselling abilities. Obstetric nurses should improve their breastfeeding counselling skills based on the needs of lactating women and provide personalized breastfeeding counselling services.

Objective To investigate the effect of fear-induced stress during pregnancy on the expression of glucose transporters(GLUT)in the placenta,providing evidence for the theory of fetal damage caused by fear-induced stress during pregnancy.Methods Twenty pregnant Wistar rats were randomly divided into a control group and a model group of 10 rats each.In the model group,a fear-induced stress model was established using the modified bystander electroshock method for 20 days.After the experiment,the number of offspring and the weights of the placenta and fetal rats were measured,and the placental efficiency was calculated.Transmission electron microscopy was used to observe the morphological changes of placental cells.Bioinformatics analysis was performed to screen for differential genes in placentas affected by pregnancy stress-phobia,and gene set enrichment analysis was performed.Protein immunoblotting(Western Blot),Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR),and immunohistochemistry were used to detect the expression levels of GLUT1,GLUT3,GLUT6,and GLUT7 proteins and genes.Results The placental efficiency was significantly reduced in the model group compared with that in the control group.The result of transmission electron microscopy in the model group showed that the placental microvilli were sparse and short and that the mitochondria and endoplasmic reticulum were swollen.Gene set enrichment analysis revealed that placental genes were significantly enriched in cellular glucose homeostasis in the model group compared with those in the control group.The result of Western Blot,Real-time PCR,and immunohistochemistry indicated a decrease in both the protein and gene expression levels of GLUT1,GLUT6,and GLUT7 in the placenta of pregnant rats.Conclusions Prenatal exposure to fear-induced stress may lead to adverse pregnancy outcomes.These adverse outcomes are potentially associated with reduced levels of three key GLUTs in the placenta:GLUT1,GLUT6,and GLUT7.

Objective To investigate the effects and mechanisms of five-element music on the social behavior of the children of mothers with fear stress during pregnancy and provide a basis for the early prevention and treatment of clinical fetogenic affective disorders.Methods Forty-five pregnant mice were randomly divided into three groups:a control group,model group,and five-element music group.The model and five-element music group models were established using the bystander electric shock method.Additionally,the five-element music group was exposed to Palace Tune five-element music daily from 17:00 to 19:00 during pregnancy.On the 19th day of pregnancy,ELISA was employed to assess the levels of adrenocorticotropin(ACTH)and cortisol(CORT)in the serum of pregnant mice in each group for modeling evaluation.The offspring were subsequently grouped with their mother and underwent an 8-week-old three-box social experiment to observe their social behavior.We used the immunofluorescence double-labeling method to detect glutamatergic neuron activity in the medial prefrontal cortex(mPFC)of the offspring.High-performance liquid chromatography was employed to measure the total glutamate(Glu)content in the mPFC,while Gorky staining was used to observe changes in the dendritic spines of mPFC neurons in the offspring.Results Compared to those in the blank group,pregnant mice in the model group exhibited a significant increase in the levels of ACTH and CORT in their serum,and there was a significant decrease in the social interaction time and social novelty preference index of their offspring.There was also a significant decrease in glutamate neuron activity,glutamate content,and neuronal dendritic spine density.In contrast,compared with those in the model group,pregnant mice in the five-element music group demonstrated a reduction in the levels of ACTH and CORT in the serum,and there were improvements in the social behavior,glutamate neuron activity,glutamate content,and condition of neuronal dendritic spines in the offspring.Conclusions Intervention with five-element music effectively ameliorated the offspring's social behavior disorder result ing from prenatal fear stress;the mechanism was potentially linked to enhanced glutamate neuron activity in the mPFC region.

Objectives:To explore the feasibility of using hemodynamic phenotypes to guide antihypertensive treatment medication. Methods:This study prospectively included 100 hypertensive patients who received outpatient treatment at Haidian Hospital in Beijing from January 2021 to December 2021.Evaluation of blood pressure was conducted using laboratory and home blood pressure measurements,impedance cardiogram(ICG)detection was performed.Following hemodynamic phenotypes and therapeutic phenotypes were established:hyperkinetic phenotype(increased heart rate)using β-blockers,large artery phenotype(increased large artery resistance index)using calcium antagonists,peripheral vascular phenotype(increased peripheral vascular resistance index)using renin angiotensin system inhibitors,and high-volume phenotype(increased blood volume saturation)using diuretics.Patients were randomly divided into ICG group(n=50,medication treatment based on hemodynamic characteristics)and control group(n=50,treatment based on hypertension guidelines and clinical experience).Patients were followed up for 8 weeks and the blood pressure reduction amplitude and compliance rate were compare between the two groups. Results:There was no statistically significant difference in baseline data such as sex,age,height,weight,and hemodynamic parameters between the two groups(all P＞0.05).There was no statistically significant difference in the types of baseline medication between the two groups(P＞0.05).After medication adjustment,the types of medication increased,but the difference between the two groups was still not statistically significant(P＞0.05).Clinic blood pressure:After 8 weeks,decreases in systolic([8.38±27.78]mmHg,1 mmHg=0.133 kPa)and diastolic([3.94±18.15]mmHg)blood pressure were greater in the ICG group as compared to the control group(both P＜0.05).The blood pressure compliance rate(＜140/90 mmHg)was higher in the ICG group than that in the control group(66.0%vs.42.0%,P＜0.05).Family blood pressure:after 8 weeks,the reduction in systolic([8.22±21.31]mmHg,P＜0.01)and diastolic([4.76±13.88]mmHg,P＜0.05)blood pressure was greater in the ICG group compared to the control group.The blood pressure compliance rate(＜135/85 mmHg)was higher in the ICG group than that in the control group(70.0%vs.48.0%,P＜0.05).Changes in corresponding hemodynamic parameters before and after two different antihypertensive drugs:the heart rate,arterial resistance index,peripheral vascular resistance index,and blood volume saturation of the ICG group all significantly decreased compared to baseline(all P＜0.05).The control group showed a significant decrease in peripheral vascular resistance index compared to baseline(P＜0.05),while there was no statistically significant difference in heart rate,large artery resistance index,and blood volume saturation compared to baseline(all P＞0.05). Conclusions:By using impedance cardiogram to assess hemodynamic phenotypes and accurately guide the selection of antihypertensive drugs based on hemodynamic phenotypes,it is possible to more effectively lower blood pressure and improve blood pressure compliance.

A middle-aged female with abnormal liver function indicators was admitted to hospital with obstructive jaundice. Urine protein of the patient was positive, and the color turned green during the retest with sulfosalicylic acid, which was relatively rare. According to the laboratory examination and other auxiliary diagnosis of the patient, the cause of the discoloration was found to be obstructive jaundice induced by choledochal adenocarcinoma, which impeded the excretion of copper ions through the bile of the patient. Copper enters the urine through the circulation of the bile, causing an increase in urinary copper. This provides a theoretical basis for the discovery of this phenomenon in clinical tests.

Objective:To investigate the effects of anterolateral femoral perforator flaps pedicled with oblique branch of lateral circumflex femoral artery and carrying fascia lata in repairing destructive wounds and rebuilding function of hands or feet.Methods:This study was a retrospective observational study. From January 2022 to March 2023, 16 patients with destructive wounds in hands or feet combined with extensor tendon defects who met the inclusion criteria were admitted to Suzhou Ruihua Orthopedic Hospital, including 12 males and 4 females, aged 3 to 63 years. The wounds were located on the hands in 12 cases and on the feet in 4 cases. The number of defective extensor tendon ranged one to five, and the length of the defect ranged from 2.5 to 6.0 cm. The wound area was 11.0 cm×5.5 cm to 29.0 cm×9.5 cm after debridement. The wounds were repaired with anterolateral femoral perforator flaps pedicled with oblique branch of lateral circumflex femoral artery and carrying fascia lata, and the flap area was 12.0 cm×6.5 cm to 30.0 cm×11.0 cm. The fascia lata was used to repair the extensor tendon defects, and the harvesting area of fascia lata was 8.0 cm×3.0 cm to 12.0 cm×8.0 cm. The wounds in flap donor areas in 15 patients were sutured directly, and the wound in flap donor area in 1 patient was covered with medium-thickness skin graft from lower abdomen. The survival of flaps and the wound healing in donor and recipient areas of flaps were observed within 1 week after operation. The number of patients who underwent thinning and plastic surgery or tenolysis was recorded during postoperative follow-up. At the last follow-up, the recovery of sensory function of the transplanted flaps on hands or feet was evaluated, the efficacy of flap repair was evaluated according to the comprehensive flap evaluation scale, and the function of hands was evaluated according to the trial standards for evaluation of partial function of upper extremity by the Hand Surgery Society of Chinese Medical Association. The following two indexes were compared, including the measured total active motion of the injured fingers and the foot function assessed using Maryland foot function scale between before surgery and at the last follow-up.Results:Arterial crisis occurred in flaps in 2 patients after operation, and the flaps survived after timely exploration; the flaps in the rest patients survived well after operation. No obvious scar hyperplasia or ulceration was observed in donor and recipient areas of flaps after operation. All patients were followed up for 8 to 16 months, of which 6 patients underwent flap thinning and plastic surgery 6 to 7 months after operation, and 4 patients underwent tenolysis 3 to 6 months after operation. At the last follow-up, the recovery of sensory function of flaps reached S1 level in 5 cases and S2 level in 11 cases, and the two-point discrimination only had 1 point. The efficacy of flap repair scored 80 to 91, which were evaluated as excellent in 5 cases, good in 9 cases, and acceptable in 2 cases. The hand function was evaluated as excellent in 5 cases, good in 5 cases, and acceptable in 2 cases. The active extension function of the injured finger/toe was reconstructed successfully, and the total active motion of the injured finger was (225±22)° at the last follow-up, which was significantly higher than (117±20)° before surgery ( t=119.59, P<0.05); the foot function score was 86±7 at the last follow-up, which was significantly higher than 29±7 before surgery ( t=222.68, P<0.05), and the foot function was evaluated as excellent in 2 cases, good in 1 case, and acceptable in 1 case. Conclusions:The operation of harvesting the anterolateral femoral perforator flap pedicled with oblique branch of lateral circumflex femoral artery is relatively simple. After the wounds on hands or feet being repaired with the flaps, the appearance and function are good, with no obvious scar hyperplasia in donor and recipient areas of flaps. The fascia lata carried by the flap can repair the extensor tendon defect at the same time and improve the movement of the finger/toe.

Objective:To prevent postoperative myocardial oedema or other causes of acute heart failure in congenital cardiac disease,anticipating delay sternal closure may reduce the number of children requiring cardiopulmonary resuscitation after surgery.The aim of this study was to describe the rate of delay sternal closure after surgery for congenital cardiac disease and to analyse the risk factors that may be associated with it.Methods:We retrospectively reviewed all surgeries with extracorporeal circulation in the cardiothoracic surgery intensive care unit of Shanghai Children's Medical Center in the past five years,from September 2014 to December 2018.The study cohort was divided into the delay sternal closure group (n=418) and the control group (routine chest closure,n=12 188) according to whether a delay sternal closure was applicated.Risk factors associated with delay sternal closure were identified by multivariate Logistic regression analysis.Results:A total of 12 606 cases were eligible,of which 418 (3.32%) were in the delayed sternal closure group.The most common cardiac diagnosis in the delayed sternal group was transposition of the great arteries (26.8%,112/418),whereas the most common cardiac diagnosis in the control group was ventricular septal defect (45.9%,5 599/12 188).All-cause mortality in children in the delayed sternal closure group was 3.3% (14/418) compared with 0.4% (46/12 188) in the control group,with a statistically significant difference ( P<0.05).Multivariate Logistic regression analysis showed that the need for delayed sternal closure were associated with age ( OR 0.164,95% CI 0.079-0.338, P<0.001),positive intropic support before surgery ( OR 0.42,95% CI 0.252-0.699, P=0.001),sex（ OR 0.742，95% CI 0.648-1.098， P<0.05），mean body weight（ OR 1.192，95% CI 1.078-1.318， P<0.001），positive intropic support before surgery（ OR 0.370，95% CI 0.252-0.699， P<0.001），complicated surgery ( OR 0.241,95% CI 0.159-0.367, P<0.001) and extracorporeal circulation diversion time ( OR 6.412,95% CI 4.339-9.475, P<0.001). Conclusion:Delayed sternal closure is an important management strategy for congenital cardiac surgery in infants and children.Delayed sternal closure is associated with age，sex,mean body weight at the time of surgery,positive intropic support before surgery，complicated surgery and extracorporeal circulation diversion time.

Objective:To investigate the value of ultrasonic measurement of the ratio of optic nerve sheath diameter (ONSD) to eyeball transverse diameter(ETD) in the diagnosis and prognosis of intracranial hypertension in patients with craniocerebral trauma.Methods:A total of 120 patients with craniocerebral trauma treated in the Xingtai General Hospital of North China Medical and Health Group from December 2021 to January 2023 were perspectively selected, and they were divided into normal intracranial pressure group (73 cases) and intracranial hypertension group (47 cases) according to the results of intracranial pressure measurements, and the intracranial hypertension group was divided into good prognosis group (20 cases) and poor prognosis group (27 cases) according to the follow-up prognosis. The efficacy of ONSD, ETD and ONSD/ETD in intracranial hypertension diagnosis and prognosis assessment were analyzed by receiver operating characteristic (ROC) curve. Kaplan-Meier method was used to evaluate the 6-month risk of adverse prognosis of patients, and the comparison was made by Log-rank test.Results:The levels of intracranial pressure, ONSD, ONSD/ETD in the normal intracranial pressure group were lower than those in the intracranial hypertension group: (130.73 ± 23.63) mmH 2O (1 mmH 2O = 0.009 8 kPa) vs. (270.11 ± 35.78) mmH 2O, (5.47 ± 0.29) mm vs. (5.78 ± 0.44) mm, 0.246 ± 0.018 vs. 0.263 ± 0.018, there were statistical differences ( P<0.05). The scores of Glasgow Coma Scale (GCS), intracranial pressure, ONSD, ONSD/ETD in the good prognosis group were lower than those in the poor prognosis group: (5.50 ± 1.24) scores vs. (6.41 ± 1.34) scores, (256.15 ± 30.23) mmH 2O vs. (280.44 ± 36.56) mmH 2O, (5.62 ± 0.40) mm vs. (5.90 ± 0.44) mm, 0.254 ± 0.014 vs. 0.270 ± 0.017, there were statistical differences ( P<0.05). ROC curve analysis results showed that the area under the curve (AUC) of ONSD and ONSD/ETD for diagnosing intracranial hypertension in patients with craniocerebral trauma were 0.718 and 0.765, respectively, and the critical values were 5.87 mm and 0.263, respectively. The AUC of ONSD and ONSD/ETD predicting prognosis of intracranial hypertension patients was 0.677 and 0.763, respectively, and the critical values were 5.90 mm and 0.267, respectively. Grouped by the threshold of ONSD/ETD for the prognosis of intracranial hypertension (0.267), the incidence of adverse prognosis in ONSD/ETD > 0.267 group was higher than that in the ONSD/ETD≤0.267 group, there was statistical difference ( P<0.05). Conclusions:ONSD/ETD can be used as an index for diagnosis and prognosis of intracranial hypertension.
