Metabolic-associated fatty liver disease (MAFLD) and osteoporosis (OP) are two very common metabolic diseases. A growing body of experimental evidence supports a pathophysiological link between MAFLD and OP. MAFLD is often associated with the development of OP. Rutaecarpine (RUT) is one of the main active components of Chinese medicine Euodiae Fructus. Our previous studies have demonstrated that RUT has lipid-lowering, anti-inflammatory and anti-atherosclerotic effects, and can improve the OP of rats. However, whether RUT can improve both fatty liver and OP symptoms of MAFLD mice at the same time remains to be investigated. In this study, we used C57BL/6 mice fed a high-fat diet (HFD) for 4 months to construct a MAFLD model, and gave the mice a low dose (5 mg·kg^-1) and a high dose (15 mg·kg^-1) of RUT by gavage for 4 weeks. The effects of RUT on liver steatosis and bone metabolism were then evaluated at the end of the experiment [this experiment was approved by the Experimental Animal Ethics Committee of Institute of Medicinal Biotechnology, Chinese Academy of Medical Sciences (approval number: IMB-20190124D₃03)]. The results showed that RUT treatment significantly reduced hepatic steatosis and lipid accumulation, and significantly reduced bone loss and promoted bone formation. In summary, this study shows that RUT has an effect of improving fatty liver and OP in MAFLD mice.

Aim To anticipate the mechanism of zuka- mu granules (ZKMG) in the treatment of bronchial asthma, and to confirm the projected outcomes through in vivo tests via using network pharmacology and molecular docking technology. Methods The database was examined for ZKMG targets, active substances, and prospective targets for bronchial asthma. The protein protein interaction network diagram (PPI) and the medication component target network were created using ZKMG and the intersection targets of bronchial asthma. The Kyoto Encyclopedia of Genes and Genomics (KEGG) and gene ontology (GO) were used for enrichment analysis, and network pharmacology findings were used for molecular docking, ovalbumin (OVA) intraperitoneal injection was used to create a bronchial asthma model, and in vivo tests were used to confirm how ZKMG affected bronchial asthma. Results There were 176 key targets for ZKMG's treatment of bronchial asthma, most of which involved biological processes like signal transduction, negative regulation of apoptotic processes, and angiogenesis. ZKMG contained 194 potentially active components, including quercetin, kaempferol, luteolin, and other important components. Via signaling pathways such TNF, vascular endothelial growth factor A (VEGFA), cancer pathway, and MAPK, they had therapeutic effects on bronchial asthma. Conclusion Key components had strong binding activity with appropriate targets, according to molecular docking data. In vivo tests showed that ZKMG could reduce p-p38, p-ERKl/2, and p-I

Objective To analyze serum characteristics and determine the reference range for thyroid function among healthy 11～16 year-old teenagers in Xi'an in order to offer a theoretical basis for clinical diagnosis and therapy.Methods A sum of 1 378 healthy 11～16 year-old teenagers who met the inclusion criteria from the First Affiliated Hospital of the Air Force Medical University(Xijing Hospital)between January 2020 and December 2022 were selected as research subjects,including 628 males and 750 females.They were divided into three groups based on age:Group 1:11～＜13 year-olds(433 cases),Group 2:13～＜15 year-olds(425 cases),and Group 3:15～≤16 year-olds(520 cases).Differences in serum thyroid function indices among different genders and age groups were analyzed,the reference ranges for these indices were established,and 99 healthy 11-16 year-old teenagers who met the inclusion criteria were chosen for verification.Results There were no significant differences between different genders in thyroid stimulating hormone[TSH,2.56(1.80,3.63)μIU/ml vs 2.43(1.68,3.48)μIU/ml]and total thyroxine[TT4,97.84(85.34,111.00)nmol/L vs 98.20(87.16,111.23)nmol/L],the differences were statistically significant(Z=-1.881,-0.638,all P＞0.05).Meanwhile,the differences in free thyroxine[FT4,16.93(15.49,18.60)pmol/L vs 16.26(14.80,17.83)pmol/L],free triiodothyronine[FT3,6.21(5.66,6.80)pmol/L vs 5.59(4.98,6.19)pmol/L],and total triiodothyronine[TT3,2.24(1.96,2.55)nmol/L vs 2.04(1.78,2.34)nmol/L]between different genders were significant(Z=-5.368,-11.994,-6.417 all P＜0.01).The differences in thyroid function indices were significant among different age groups(Z=10.649～261.003,all P＜0.05).The reference ranges for thyroid function indices across different age groups and genders were established,in which thyroid function indicators were verified to be within the established reference range by 99 samples.Conclusion Teenage hormone secretion varies greatly,and the secretion of thyroid hormones is influenced by various factors.Thus,the diagnosis and treatment of teenage thyroid diseases cannot fully rely on the reference ranges provided by adults or manufacturers.This study established the reference range of the thyroid function indices of 11～16 year-old teenagers in Xi'an,offering clinical doctors'diagnosis and treatment data support.

Objective:To investigate the incidence of radiation pneumonitis (RP) induced by 125I seed implantation for the treatment of malignant lung tumors and analyze related dosimetric parameters. Methods:A retrospective analysis was conducted on 31 cases of malignant lung tumors treated with 125I seed implantation from January 2017 to December 2022 at Hebei Provincial Tumor Radioactive Seeds Implantation Diagnosis and Treatment Center. These cases consisted of eight patients with squamous cell carcinoma, 10 patients with adenocarcinoma, and 13 patients with metastatic cancer in other sites. At 1-6 months after treatment, these patients received postoperative chest CT scans, with the efficacy evaluated based on the Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1), including the objective response rate (ORR) and the disease control rate (DCR). The efficacy of RP was evaluated using the Radiation Therapy Oncology Group (RTOG) criteria. Postoperative dosimetric parameters, including D90 (minimum peripheral dose received by 90% of the target volume), V8 (percentage of lung volume receiving 8 Gy), V32 (percentage of lung volume receiving 32 Gy), and Dmean (mean radiation dose) of the affected lung, were statistically analyzed. The relationships of the RP occurrence with postoperative D90, V8, V32, and Dmean were analyzed by comparison with relevant external radiotherapy data, to identify the parameters that are correlated closely with RP occurrence. Results:All the patients underwent successful surgeries. The postoperative efficacy evaluation after six months showed complete response (CR) in 11 cases, partial response (PR) in 11 cases, stable disease (SD) in eight cases, and progressive disease (PD) in one case, with an overall response rate (ORR) of 71.0%, and a disease control rate (DCR) of 96.8%. Three patients suffered RP, with an incidence rate of 9.7%. Postoperative V8, V32, and Dmean could not serve as predictive indicators for RP. Follow-up observation revealed that three RP cases (3/5) exhibited postoperative D90 exceeding 170 Gy and no RP cases (0/26) showed postoperative D90 below 170 Gy. Conclusions:In the treatment of malignant lung tumors with 125I seed implantation, there is a certain correlation between RP and postoperative D90, while there is no correlation between it and V8, V32, and Dmean.

Objective:To investigate the value of systemic inflammatory response syndrome (SIRS), pediatric sequential organ failure assessment (pSOFA) and pediatric critical illness score (PCIS) in predicting mortality of pediatric sepsis in pediatric intensive care units (PICU) from Southwest China.Methods:This was a prospective multicenter observational study. A total of 447 children with sepsis admitted to 12 PICU in Southwest China from April 2022 to March 2023 were enrolled. Based on the prognosis, the patients were divided into survival group and non-survival group. The physiological parameters of SIRS, pSOFA and PCIS were recorded and scored within 24 h after PICU admission. The general clinical data and some laboratory results were recorded. The area under the curve (AUC) of the receiver operating characteristic curve was used to compare the predictive value of SIRS, pSOFA and PCIS in mortality of pediatric sepsis.Results:Amongst 447 children with sepsis, 260 patients were male and 187 patients were female, aged 2.5 (0.8, 7.0) years, 405 patients were in the survival group and 42 patients were in the non-survival group. 418 patients (93.5%) met the criteria of SIRS, and 440 patients (98.4%) met the criteria of pSOFA≥2. There was no significant difference in the number of items meeting the SIRS criteria between the survival group and the non-survival group (3(2, 4) vs. 3(3, 4) points, Z=1.30, P=0.192). The pSOFA score of the non-survival group was significantly higher than that of the survival group (9(6, 12) vs. 4(3, 7) points, Z=6.56, P<0.001), and the PCIS score was significantly lower than that of the survival group (72(68, 81) vs. 82(76, 88) points, Z=5.90, P<0.001). The predictive value of pSOFA (AUC=0.82) and PCIS (AUC=0.78) for sepsis mortality was significantly higher than that of SIRS (AUC=0.56) ( Z=6.59, 4.23, both P<0.001). There was no significant difference between pSOFA and PCIS ( Z=1.35, P=0.176). Platelet count, procalcitonin, lactic acid, albumin, creatinine, total bilirubin, activated partial thromboplastin time, prothrombin time and international normalized ratio were all able to predict mortality of sepsis to a certain degree (AUC=0.64, 0.68, 0.80, 0.64, 0.68, 0.60, 0.77, 0.75, 0.76, all P<0.05). Conclusion:Compared with SIRS, both pSOFA and PCIS had better predictive value in the mortality of pediatric sepsis in PICU.

Objective Based on the theory of five circuits and six qi,the characteristics of circuit-qi indicators of the date of birth of hospitalized patients with pneumonia of Shaoyin-disease syndrome were explored.Methods The data collection was conducted in 422 hospitalized patients with pneumonia of shaoyin-disease syndrome admitted to the Department of Classical Chinese Medicine,Fangcun Hospital of Guangdong Provincinal Hospital of Chinese Medicine from January 20,2012 to June 30,2022.And then statistical analysis was performed for circuit-qi indicators of the date of birth of the patients.Results The goodness of fit by chi-square test showed that there were statistically significant differences in the distribution of the heavenly-stem year,earthly-branch year,yearly circuit,recombinant yearly circuit,predominant qi,and sitian-zaiquan(circuit qi of the first and second half of a year)at birthdate of hospitalized patients with pneumonia of shaoyin-disease syndrome(P＜0.05 or P＜0.001).And the results indicated that a higher risk of suffering from pneumonia of shaoyin-disease syndrome existed in the population born in the heavenly-stem ji year and earthly-branch chou year,in the yearly circuit being deficient earth circuit,in the recombinant yearly circuit being wind,in the predominant qi being taiyin damp earth,and in the sitian-zaiquan being taiyin damp earth and taiyang cold-water.Conclusion There is a correlation between the incidence of pneumonia of shaoyin-disease syndrome and the circuit-qi indicators of the date of birth of the patients,and the pathogenesis of circuits and qi at birth date is probably related with yang deficiency of spleen and kidney,and cold interweaved with dampness.

Aim To establish limited sampling strategy to esti-mate area under the drug concentration versus time curve(AUC0-t)of lymphoma patients treated with autologous stem cell transplantation(ASCT)who had busulfan intravenous infu-sion.Methods Twelve lymphoma patients treated with ASCT received a conditioning regimen containing busulfan 105 mg·m-2,Ⅳ infusion for 3 h.Blood samples were obtained 1 h after the start of the first dose of the busulfan infusion,at 5 min,1 h,2 h,4 h,6 h and 18 h after the end of the drug administration.LC-MS/MS was used to determine the busulfan serum concentra-tion.After obtaining the clinical pharmacokinetic parameters of busulfan by traditional pharmacokinetic method,multiple linear stepwise regression analysis was used to establish the AUC0-t es-timation model of busulfan based on limited sampling method.The model was further verified by Jackknife and Bootstrap meth-od.Bland-Altman plots were used to evaluate the consistency between the limited sampling method and the classical pharma-cokinetic method.Results The multiple linear regression equa-tion analysis of C60min,C180min and C300min was obtained by the limited sampling method.The regression equation was AUC0-t=295.003C60min+233.050C180min+273.163C300min-1202.713,r2=0.995,MPE=-0.87％,RMSE=2.40％.Conclusion The limited sampling model with three-point estimation can be used to estimate the AUC0-t of busulfan exposure in lymphoma patients with ASCT to provide reference for clinical application of busulfan.

Objective:To investigate the curative effect of transvaginal sacrospinous ligamentopexy combined with traditional per-vaginam surgery in the treatment of moderate and severe pelvic organ prolapse.Methods:A total of 125 patients with moderate to severe pelvic organ prolapse admitted to the Third People′s Hospital of Yancheng from June 2021 to May 2023 were retrospectively selected as the study objects. They were divided into two groups according to the surgical methods. The observation group (73 cases) received transvaginal sacrospinous ligamentopexy combined with traditional per-vaginam surgery, and the control group (52 cases) received traditional Yin surgery. The primary outcome was anatomic cure rate between the two groups, and the secondary outcome was surgical index, quality of life and recurrence.Results:There were significant differences in the anatomical cure rate [78.1%(57/73) vs 61.5%(32/52)] and postoperative hospital stay between the observation group and the control group at 6 months after surgery (all P<0.05). There was no significant difference in operation time, amount of blood loss and pain degree 24 h after operation between the two groups ( P>0.05). There was no significant difference in Pelvic Floor Distress Inventory-Short Form 20 (PFDI-20) scores between the two groups before operation ( P>0.05). PFDI-20 scores in both groups were lower than those before surgery 6 months after surgery, and PFDI-20 scores in the observation group were lower than those in the control group, with statistical significance ( P<0.05). After follow-up, 3 cases (8.3%) recurred in the observation group and 6 cases (13.3%) in the control group. There was no statistical significance in the recurrence rate between the two groups ( P>0.05). Conclusions:Transvaginal sacrospinous ligamentopexy combined with traditional per-vaginam surgery can effectively treat moderate and severe pelvic organ prolapse, improve the quality of life of patients, and have a good long-term effect.
