OBJECTIVE To investigate the equivalence of different decoction processes based on rat model of hypertension with liver-yang hyperactivity. METHODS Inductively coupled plasma mass spectrometry （ICP-MS） was used to compare the dissolution differences of inorganic elements in the powder-directly-decocted decoction versus the pieces-decocted-first decoction of Ostreae Concha- Haliotidis Concha- Margaritifera Concha drug pair. Six SD rats were included in the normal group. The spontaneously hypertensive rats were given Aconite decoction for six weeks to induce the hypertension model with liver-yang hyperactivity. After successful modeling， 48 rats were randomly divided into the model group， the captopril group [positive control， 8 mL/（kg·d） ] ， as well as low-， medium-， and high-dose groups of pieces decocted first or directly powder decocted [2.02， 4.05， 8.10 mL/（kg·d） ] ， with 6 rats in each group. Each group received the corresponding drug or equal volume of pure water intragastrically， once a day， for two consecutive weeks. After the last administration， the degree of irritability， facial temperature， pressure pain threshold， blood pressure， and pathological changes of the thoracic aorta were observed in each group. Serum nitric oxide （NO） and plasma angiotensin Ⅱ （Ang Ⅱ）， renin， and aldosterone （ALD） levels were also measured. RESULTS ICP-MS analysis results showed statistically significant differences in the contents of macroelements Li， Na， Mg， Ca， Mn， Ga， Sr， Mo， Cd， Sn， and Sb， between the powder-directly-decocted decoction and the pieces-decocted-first decoction （ P ＜0.05） ，the elements P， Cr， Fe， Ni， Zn， Hg， Tl， and Pb were not detected in either decoction. Animal experiments showed that after two weeks of administration， compared with the model group， the facial temperature， and blood pressure decreased in all treatment groups， while the pressure pain threshold increased； plasma levels of Ang Ⅱ， renin and ALD， as well as the serum level of NO were all decreased， and thoracic aortic media thickness was significantly reduced， most of the differences in the above indicators were statistically significant （ P ＜0.05 or P ＜0.01 or P ＜0.001）. Pathological observation showed improvement in thoracic aortic pathological injury. CONCLUSIONS The powder-directly-decocted process for the Ostreae Concha- Haliotidis Concha- Margaritifera Concha drug pair significantly promotes the dissolution of key elements such as Ca， Mg， and Sr without increasing the dissolution of harmful elements. It is equivalent to the traditional pieces-decocted-first in alleviating liver-yang hyperactivity syndrome， lowering blood pressure， and protecting the vascular endothelium， and even shows better performance in some indicators.

OBJECTIVES: To evaluate the clinical utility and translational potential of a remote jaundice monitoring system for home-based screening of neonatal hyperbilirubinemia. METHODS: A prospective self-controlled study was conducted, enrolling 538 newborns with gestational age ≥35 weeks, birth weight ≥2 000 g, and postnatal age ≤14 days at the Women's Hospital of Nanjing Medical University from March to October 2023. Four screening protocols with different predictive indicators were developed based on the Chinese Neonatal Transcutaneous Hourly Bilirubin Nomogram. The effectiveness of the system was evaluated, and the feasibility of using the remote jaundice monitoring system in actual home settings was analyzed. RESULTS: A total of 538 paired transcutaneous bilirubin (TcB) and total serum bilirubin (TSB) measurements showed a strong correlation (r=0.85, P<0.001), with 95.0% (511/538) of samples within the 95% limits of agreement. Using TcB ≥ the 95th percentile as the predictive indicator, the system achieved 100% sensitivity, 46.2% specificity, and an area under the receiver operating characteristic curve of 0.731 (95%CI: 0.682-0.780). This approach could reduce unnecessary hospital visits by 41.4% (221/538). CONCLUSIONS The system integrates the QBH-801 transcutaneous bilirubinometer, intelligent early warning, and remote guidance services, establishing a closed-loop "hospital-to-home" management model. It demonstrates high safety and feasibility, with significant clinical translational value.

Aim To investigate the anti-acute lung injury(ALI)effect of Sterculiae Lychnophorae Semen(SLS)and its mechanism.Methods The main ac-tive components of SLS and their core targets and path-ways of action against ALI were obtained by network pharmacology methods.Subsequently,molecular doc-king technology and in vitro cellular experiments were applied for validation.Results A total of 19 core tar-gets were obtained,including HSP90AA1,CASP3,TNF,MAPK8 and MAPK14.The mechanisms may in-volve signaling pathways such as cancer,PI3K/Akt and MAPK.Molecular docking confirmed that the key targets of SLS formed a better binding activity with the relevant active ingredients.The in vitro results showed that SLS was able to protect the PM2.5-contaminated BEAS-2B cells,inhibit their NO,IL-1β and TNF-αlevels,and reduce the expression of p-p38 MAPK and p-JNK proteins.Conclusions The study successfully predicts the active ingredients,targets and signaling pathways of SLS against ALI,and in vitro experiments demonstrate that SLS might protect BEAS-2B cells from PM2.5 stimulus-induced inflammation and apoptosis by inhibiting the over-activation of p38 MAPK and JNK signaling pathways.

Objective To investigate the application value of peripheral blood soluble human leukocyte antigen-G(sHLA-G)combined with immune cytokines in the differential diagnosis of renal transplant rejection.Methods This case-control study retrospectively analyzed 81 renal transplant patients hospitalized in the Department of Organ Transplantation,the Second Affiliated Hospital of Naval Medical University from April 2020 to December 2023,due to elevated serum creatinine.Among them,32 patients were diagnosed with acute rejection(acute rejection group),29 with chronic rejection(chronic rejection group),and 20 with elevated creatinine due to non-rejection causes(non-rejection group).Fifty renal transplant inpatients and outpatients with normal and stable serum creatinine were selected as control group during the same period.Clinical data such as gender,age,serum creatinine,estimated glomerular filtration rate(eGFR),and urine protein positive rate,etc.were collected.Peripheral blood of patients was sampled to measure the levels of plasma sHLA-G and immune cytokines[interferon-γ(IFN-γ),tumor necrosis factor-β(TNF-β),interleukin(IL)-2,IL-4,IL-10,IL-5,IL-6,IL-17]using enzyme-linked immunosorbent assay(ELISA).Stratify and compare the differences in sHLA-G levels among different groups and all renal transplant inpatients by gender.Results Compared with control group,serum creatinine levels and urine protein positive rate were significantly higher in acute rejection group,chronic rejection group,and non-rejection group,while eGFR was significantly lower,serum creatinine levels in chronic rejection group and non-rejection group were higher than those in acute rejection group,while eGFR was lower than that in acute rejection group,with statistically significant differences(P<0.05).No statistically significant differences were observed in gender,age,blood type,body mass index,transplantation duration,and immunosuppressive agent use among acute rejection,chronic rejection,non-rejection,and control groups(P>0.05).Plasma sHLA-G levels in acute rejection and chronic rejection groups were significantly lower than those in control group[(19.665±11.233)U/ml vs.(24.785±21.668)U/ml vs.(44.918±39.898)U/ml,P<0.05].The sHLA-G/IL-2 ratio in chronic rejection group was significantly higher than that in acute rejection group(5.844±6.248 vs.1.825±1.574,P<0.05),and the sHLA-G/IFN-γ ratio in non-rejection group was significantly higher than that in chronic rejection group(3.452±3.283 vs.1.543±2.030,P<0.05).Among 131 renal transplant inpatients,female sHLA-G levels were significantly higher than male(P<0.05).Within each group,female sHLA-G levels in chronic rejection group were significantly higher than male(P<0.05).Although female sHLA-G levels in acute rejection,non-rejection,and control groups were higher than those of male,the gender difference was not statistically significant(P>0.05).Conclusions Peripheral blood sHLA-G levels are correlated with renal transplantation rejection.The application of sHLA-G/IL-2 and sHLA-G/IFN-γ ratios has potential value in the diagnosis and differentiation of elevated creatinine caused by acute/chronic rejection,chronic rejection and non-rejection causes,respectively.

Objective:To investigate factors influencing frequent episodes (≥ 4 episodes within 1 year) in children with moderate-to-severe atopic dermatitis (AD) in China.Methods:A national multicenter cross-sectional study was conducted. Patients under the age of 18 years diagnosed with moderate-to-severe AD were enrolled at dermatology clinics in 18 medical institutions across 12 provinces and municipalities in China between June 12 and August 8, 2023. At the time of the visit, their guardians completed a structured questionnaire covering demographic characteristics, clinical features of AD, personal and family history, factors associated with frequent episodes of moderate-to-severe AD, compliance with treatment, and disease awareness. Statistical analyses included t tests, one-way analysis of variance, rank-sum tests, and chi-square tests, with multiple-response analysis applied for multiple-choice questions. Results:A total of 965 valid questionnaires were collected, and 965 children with moderate-to-severe AD were included. Among them, there were 531 males and 434 females, 678 (70.3%) were aged 2 - < 12 years, 837 (86.7%) were from urban areas, the age at onset was 2.47 ± 3.03 years, and the median frequency of AD episodes in the past year was 4 times. These children were divided into 2 groups based on the median episode frequency: < 4-episode group (439 cases, 45.5%) and ≥ 4-episode group (526 cases, 54.5%). Compared with the < 4-episode group, children in the ≥ 4-episode group showed younger ages at onset (2.22 ± 2.98 years vs. 2.76 ± 3.06 years, P = 0.006) and higher proportions of patients with comorbid allergic diseases in both the children themselves (82.9% [436/526] vs. 69.7% [306/439], χ2 = 23.42, P < 0.001) and their relatives (66.0% [347/526] vs. 57.4% [252/439], χ2 = 7.46, P = 0.006). Children in the ≥ 4- episode group also had higher monthly usage of moisturizers (150 [30, 300] g vs. 60 [6, 200] g) and daily frequency of moisturizer use, greater disease awareness, but more severe fear of medication use (all P < 0.05). The region and the human development index level were both significantly associated with the episode frequency (both P < 0.001), with the highest proportion of children from South China in the ≥ 4- episode group (36.3%, 191/526). Children in the ≥ 4-episode group also had a longer duration of topical glucocorticoid use than those in the < 4-episode group ( Z = -2.21, P = 0.027). External triggers associated with AD episodes mainly included heat exposure (50.36%, 486/965), hot water bathing (40.73%, 393/965), seafood (23.52%, 227/965), and dust mites (33.37%, 322/965) . Conclusion:In children with moderate-to-severe AD in China, factors influencing frequent episodes may include residence in southern or economically developed regions, earlier age at onset, having a personal or family history of allergic diseases, and fear of medication use.

Objective:To explore the current status and influencing factors of intrinsic capacity in elderly patients with Parkinson's disease.Methods:Convenience sampling was used to select 306 elderly patients with Parkinson's disease who attended Xuanwu Hospital of Capital Medical University from March to September 2024 for the study. Influencing factors were screened based on the health ecology model. Elderly patients with Parkinson's disease were surveyed using the General Information Questionnaire, Connor-Davidson Resilience Scale, Family APGAR Scale, Social Support Rating Scale, and Intrinsic Capacity Assessment Tool. Multiple linear regression was used to analyze the factors influencing the total score and the scores of each dimension of intrinsic capacity in elderly patients with Parkinson's disease.Results:A total of 306 questionnaires were distributed and 301 valid questionnaires were recovered, with a valid recovery rate of 98.37% (301/306). The total intrinsic capacity score of 301 elderly patients with Parkinson's disease was (67.21±11.47), of which 297 elderly patients with Parkinson's disease had impaired intrinsic capacity, and the rate of impaired intrinsic capacity was 98.7% (297/301). The dimensions in descending order of impairment were motor [89.7% (270/301) ], mental [76.1% (229/301) ], sensory [70.4% (212/301) ], vitality [38.2% (115/301) ], and cognitive [25.6% (77/301) ]. Multiple linear regression analysis showed that age, Hoehn-Yahr staging, levodopa equivalent dosage, activity of daily living, history of falls, regular exercise, psychological resilience, social support, and monthly income were the factors influencing the total intrinsic capacity score of elderly patients with Parkinson's disease ( P<0.05) and heterogeneity of influencing factors in each dimension. Conclusions:Elderly patients with Parkinson's disease have a high rate of impaired intrinsic capacity, with the motor dimension being the most severely impaired. Healthcare professionals should pay attention to the assessment of the intrinsic capacity of elderly patients with Parkinson's disease, and customize interventions according to the influencing factors to promote the functioning of elderly patients so as to reduce the burden of care on families and society.
