Objective:To study the composition and influencing factors of hospitalization expenses of patients with sequelae of ce-rebral infarction caused by the dominant diseases of traditional Chinese medicine(TCM),so as to provide references for the fine management within the hospital and the medical insurance department to improve the payment policy suitable for the characteristics of TCM.Method:A total of 1 261 cases with ICD code 169.3 in the sample of tertiary traditional Chinese medicine hospitals from 2020 to 2022 were collected.Single factor analysis,correlation analysis,multiple linear stepwise regression and other methods were used to analyze the composition and main influencing factors of hospitalization expenses of patients with cerebral infarction sequelae.Re-sults:The average length of hospital stay of patients with sequelae of cerebral infarction was 16.71 days per time,the average hospi-talization cost was 24 148.83 yuan per time,and the proportion of TCM treatment cost per time was 54.43％.The results of stepwise regression showed that the length of stay,the condition of admission and the complication of pulmonary infection had a significant im-pact on the hospitalization expenses(P＜0.05),and the length of stay had the greatest impact.Conclusion:It is suggested that the hospital should optimize and improve the clinical pathway of TCM dominant diseases and establish an effective dynamic management mechanism,and the medical insurance department should improve the adjustment mechanism of the auxiliary list of TCM dominant diseases under the disease scoring payment.

Objective:To investigate the characteristics of early motor development in small for gestational age (SGA) infants at high risk of brain injury.Methods:This study retrospectively enrolled a total of 81 SGA infants and appropriate for gestational age (AGA) infants who were at high risk of brain injury and attended outpatient follow-up visits in Xi'an Children's Hospital from February to October 2022. Seventeen SGA infants (SGA group) and 24 AGA infants (AGA group) were assessed for motor development using the Test of Infant Motor Performance (TIMP) at 2-5 weeks of corrected age (CA) and 20 SGA infants (SGA group) and 20 AGA infants (AGA group) were assessed at 14-17 weeks of CA. Independent samples t-test, rank-sum test, and Chi-square test were used to compare the demographic characteristics, high-risk factors of brain injury, and TIMP scores between the two groups. Results:At 2-5 weeks and 14-17 weeks of CA, the birth weights of SGA group were both less than those of AGA group [(1 817.1±440.3) vs. (2 630.0±560.9) g, t=－4.98; (1 752.0±434.4) vs. (2 226.3±699.8) g, t=－2.58; both P<0.05], but there were no significant differences in gestational age at birth or high-risk factors of brain injury between the two groups (all P>0.05). (1) At 2-5 weeks of CA: SGA group had lower total TIMP score [(71.6±13.7) vs. (80.5±11.5) scores, t=－2.26, P=0.029], elicited item score [61.0 scores (41.0-85.0 scores) vs. 69.1 scores (49.0-96.0 scores), Z=－2.15, P=0.037], sitting position score [8.8 scores (3.0-19.0 scores) vs. 11.2 scores (5.0-22.0 scores), Z=－2.07, P=0.038], and prone position score [(9.8±3.1) vs. (12.3±3.1) scores, t=－2.19, P=0.034] when compared with AGA group. (2) At 14-17 weeks of CA: The standing position score of the SGA group was lower than that of the AGA group [6.5 scores (4.0-11.0 scores) vs. 7.7 scores (2.0-11.0 scores), Z=－2.05, P=0.040], but no statistical difference was observed in the total TIMP score or the scores of sitting, supine, prone, turning, and lateral positions between the two groups (all P>0.05). Conclusion:Early motor performance of SGA infants is inferior to AGA infants before five months of age, which is embodied in the poor head control at 2-5 weeks of CA that further affects the stability of standing posture in them at 14-17 weeks of CA.

In this study,the immunological characteristics of the PhoP protein were explored with a two-component system of Mycobacterium tuberculosis(Mtb).Bioinformatics was used to predict the B and T cell epitopes of the PhoP protein.A re-combinant expression plasmid was constructed by PCR analysis of the phoP sequence and cloning into the prokaryotic expres-sion vector pET-28a(+).Competent Escherichia coli BL21 cells were transformed with the recombinant plasmid and expres-sion was induced with IPTG.The recombinant PhoP protein was purified by affinity chromatography.Serum levels of PhoP-specific antibodies in Mtb-infected mice and tuberculosis(TB)patients were analyzed with an ELISA.BALB/c mice were im-munized with the PhoP recombinant protein by intramuscular injection.Sera of mice were collected and antibody titers were detected with an ELISA and specificity was assessed by West-ern blot analysis.Mouse splenocytes were isolated and the pro-portions of IFN-y-positive cells and cytokine levels were detec-ted with an ELISpot and ELISA,respectively.Bioinformatics i-dentified 24 B cell and 11 T cell epitopes of the PhoP protein.A prokaryotic recombinant vector of PhoP was successfully con-structed and the recombinant PhoP protein was obtained by purification.Specific antibody levels to PhoP in sera of Mtb in-fected mice and TB patients increased significantly,with preci-sion of 99.9％and 82.5％,and specificity of 100％,respectively.PhoP protein immunization successfully induced production of specific antibodies in mice.Stimulated by antigens in vitro,IL-2 and IFN-γ levels were significantly increased in the splenocytes of immunized mice.Immunization with the PhoP protein induce a humoral immune response and Thl-dominated cellular immu-nity,indicating that the PhoP protein was immunogenic with diagnostic efficacy for TB.These results lay a foundation to clari-fy the role of PhoP in Mtb infection and application for diagnosis and prevention of TB.

Objective:To assess the effect of mild intraventricular hemorrhage（IVH）on the early motor development of infants at high risk of brain injury,and to guide the intervention according to its characteristics.Methods:A retrospective cohort study was conducted to select neonates discharged from the Neonatal Unit of Xi 'an Children 's Hospital from February 1，2022 to March 31，2023，with one or more high-risk factors of brain injury.The patients were assigned to low-grade IVH group and no IVH group according to ultrasound diagnosis.The research subjects exclucled other brain injury diseases besides mild IVH.Motor development was assessed using test of infant motor performance(TIMP)，reflecting performance in head control，auditory and visual responses，defensive movements，trunk movements，limb movements，and more.Both groups completed TIMP assessment between discharge and 16 weeks of the corrected age(CA).The differences of TIMP scores between two groups were compared . Results:A total of 329 neonates at high risk for brain injury were recruited，including 98 cases with grade Ⅰ-Ⅱ IVH（low-grade IVH group）diagnosed through brain ultrasonography and 231 controls(no IVH group).The Z scores of TIMP in the low-grade IVH group were lower than that in no IVH group（-0.25 ±0.87 vs.0.03 ±0.71， P=0.015）.The risk factors of brain injury were matched for further comparison.At CA2-5 weeks，the scores in low-grade IVH group of TIMP total scores（74.10 ±12.28 vs.84.24 ±7.71），observation items（10.57 ±1.47 vs.11.24 ±1.29），elicitation（63.17 ±12.13 vs.73.00 ±7.36），sitting（9.14 ±2.90 vs.11.65 ±3.26），supine（22.07 ±4.73 vs.24.79 ±3.55），prone position（10.35 ±3.74 vs.12.82 ±3.15）and lateral position（4.00 ±2.85 vs.5.48 ±2.13）were significantly lower than those in no IVH group（ P<0.05）.At CA6-9 weeks，the scores in low-grade IVH group of sitting position（10.44 ±4.01 vs.12.96 ±3.02），supine position（24.04 ±4.60 vs.26.83 ±3.53），lateral position（4.83 ±2.53 vs.6.25 ±2.6）were significantly lower than those in no IVH group（ P<0.05）.At CA12-15 weeks，the low-grade IVH group showed significant differences in TIMP total score（104.00 ±12.98 vs.114.10 ±13.16），elicitation（92.00 ±12.64 vs.102.00 ±13.10），sitting（17.00 ±3.50 vs.19.13 ±3.55）and lateral position（7.35 ±2.14 vs.9.00 ±2.37）compared with those from no IVH group（ P<0.05）. Conclusion:Mild intraventricular hemorrhage affected the early motor development of high-risk infants with brain injury，mainly manifested as a lag in the ability of head control at CA2-5 weeks，and the trend continued until CA12-15 weeks.Early monitoring of motor ability and intervention of head control ability should be carried out in high-risk children with mild intraventricular hemorrhage.

Four new triterpenoids, together with six known analogues, were isolated from an aqueous extract of the Ziziphus jujuba var. spinosa seeds, by multiple column chromatographic separation methods using stationary phases of macroporous adsorption resin, MCI resin, normal phase silica gel, Sephadex LH-20, and Toyopearl HW-40C as well as preparative thin-layer chromatography and reversed-phase HPLC.

The structure of 1 was confirmed by single crystal X-ray diffraction.

Objective:To assess the characteristics and correlation of motor development in preterm infants of different gestational weeks by using the Test of Infant Motor Performance (TIMP) method, and to develop better individualized early interventions based on TIMP test results.Methods:A prospective study involving 43 full-term healthy infants and 77 preterm followed up in 3201 Hospital from June 2019 to July 2021 was conducted.Preterm infants were divided into the early preterm group (39 cases) and late preterm group (38 cases) according to their gestational age at birth.TIMP assessment was performed at the gestational age of 40 weeks and the corrected age of 16 weeks after birth.Similarly, the full-term healthy infants were assessed by TIMP at the postnatal age of 16 weeks.The differences between groups were investigated using ANOVA or Mann- Whitney rank sum test.Correlations were analyzed by the Pearson correlation method. Results:There were no significant difference in TIMP scores between early and late preterm infants at the gestational age of 40 weeks [(65.74±6.52) scores vs.(66.96±8.51) scores] and the corrected age of 16 weeks [(101±10) scores vs.(104±8) scores] (all P>0.05). TIMP scores in the full-term healthy group at the corrected age of 16 weeks [(108±10) scores] differed significantly from those of early and late preterm infants ( P<0.05). Compared with full-term infants, early and late preterm infants had lower TIMP scores in observation, supine position, and supine turning (all P<0.05), but a higher TIMP score in standing position ( P<0.05). For both early and late preterm infants, TIMP scores at the gestational age of 40 weeks were significantly positively correlated with those at the corrected age of 16 weeks ( r=0.565, 0.302, all P<0.01). Conclusions:There were significant differences in motor development between preterm infants of different gestational ages and term infants, which had guiding significance for early intervention.English version TIMP could play a positive role in promoting individualized follow-up and early intervention of preterm infants in China.

Objective: To investigate the diagnosis value of myocardial work (MW) in evaluating left ventricular global systolic function among acute myocardial infarction (AMI) patients with preserved ejection fraction (LVEF). Methods: This study was a diagnostic trial in a prospective case-control design. AMI patients with preserved LVEF were enrolled as AMI(LVEF>50%) group and age and sex-matched healthy individuals undergoing healthy checkup in our hospital were collected as control group. Two-dimensional dynamic images, including standard apical two-chamber, long-axis and four-chamber views in 3 consecutive cardiac cycles were acquired. General clinical data, routine echocardiography and myocardial work parameters were obtained from all subjects. The indices were compared between the two groups. Intra-observer and inter-observer repeatability of myocardial work parameters were evaluated by intra-group correlation coefficient (ICC). Receiver operator characteristic (ROC) curve was used to determine the diagnostic value of global constructive work (GCW), global wasted work (GWW), global work efficiency (GWE) and global work index (GWI) on the reduction of left ventricular global systolic function in AMI(LVEF>50%) group. Results: There were 30 patients in AMI(LVEF>50%) group, the age was (67.3±9.7)years, and 14 cases were female(46.7%). Thirty participants were included in the control group, the age was (68.1±8.6)years, and 12 cases were female (40.0%). Compared with the control group, left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), interventricular septum thickness (IVSD), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), peak early diastolic velocity of mitral orifice/tissue Doppler velocity of posterior mitral annulus (E/e), left ventricular mass (LVM), left ventricular mass index (LVMI) were significantly higher, while E and e values were significantly lower in AMI (LVEF>50%) group (all P<0.05). Compared with the control group, GCW ((1 145.9±440.1)mmHg% (1 mmHg=0.133 kPa) vs. (1 425.7±355.4)mmHg%), GWE ((80.9±9.5)% vs. (87.3±5.5)%), GWI ((1 001.3±416.2)mmHg% vs. (1 247.6±341.7)mmHg%) and the absolute value of long axis integral strain (GLS) ((8.5±3.4)% vs. (11.4±3.7)%) were significantly lower, while peak strain dispersion(PSD)((101.3±66.4)ms vs. (74.7±31.9)ms) was significantly higher in AMI(LVEF>50%) group (P all<0 05). There was no significant difference in GWW((177.2±71.1)mmHg% vs. (155.7±64.6)mmHg%) between the two groups (P>0.05). The reproducibility of GCW, GWW, GWE and GWI within and between observers were satisfactory (all ICC>0.75). ROC curve analysis showed that all four parameters, GCW, GWW, GWE, and GWI, could be used for the diagnosis of reduced left ventricular systolic function in patients with AMI (LVEF>50%), and their areas under the ROC curve were 0.896,0.929,0.808,0.862. Conclusion: Myocardial work assessment is valuable on diagnosing left ventricular global systolic function reduction in AMI patients with preserved LVEF.

Aim To discuss the potential key mechanism of mogroside V in relieving pulmonary inflammation in asthmatic mice based on transcriptomics and proteomics. Methods Ovalbumin(OVA)was chosen to induce female BALB/C mouse asthma model, and the mice were treated with mogroside V to observe the pathological changes of lung tissues. Lung tissues in groups of natural control, ovalbumin control and mogroside V control were chosen for transcriptomic and proteomic analysis, and differential genes and proteins were screened for tendency analysis, followed by KEGG enrichment analysis for the potential genes and proteins. Results The results of lung morphological observation and HE revealed that mogroside V attenuated the OVA-induced pulmonary inflammation. Differential genes and proteins were selected from RNA-seq and DIA analysis. In the analysis of omics 454 genes increased in comparison between groups of natural control with ovalbumin control and decreased in comparison between groups of mogroside V control with ovalbumin control in 1 122 potential genes, and 111 genes were of opposite features. A total of 238 proteins increased in comparison between groups of natural control with ovalbumin control and decreased in comparison between groups of mogroside V control with ovalbumin control in 497 potential proteins, and 91 proteins were of opposite features. The PI3K/Akt signaling pathway was enriched from KEGG and tendency analysis of transcriptomics and proteomics. The key factors of Igha, Ighg1, PI3K and Akt increased in ovalbumin control group and decreased in mogroside V control group by the validation of molecualr biology experiments. Conclusions Transcriptomic and proteomic analysis exhibits that mogroside V relieves asthma in mice through inhibiting the activation of key factors including Lgha, Lgh1, PI3K and Akt, depressing the signaling pathway, attenuating pulmonary inflammation to reach the goal of moistening lung and relieve cough, which provides a reference for drug development of asthma.
