ObjectiveTo assess the therapeutic effectiveness and safety of the traditional Chinese medicine compound Shenlong decoction in addressing the symptoms of pulmonary deficiency and stasis in patients with idiopathic pulmonary fibrosis （IPF）. MethodsSixty eligible patients with lung deficiency and collateral stasis syndrome of IPF were randomly assigned to the observation （30 patients） and control groups （30 patients）. All patients underwent standard Western medical therapy. Additionally，the observation group received Shenlong decoction granules，while the control group received a placebo. Both treatments were packaged in four doses of 10.5 g each，taken twice daily for three months. The indexes of the patients during the treatment cycle were observed，and the main indexes include traditional Chinese medicine （TCM） syndrome scores and 6 min walk test （6MWT）. The secondary indexes include pulmonary function test ［actual value/expected value of total lung volume （TLC%），actual value/expected value of vital capacity（FVC%），actual/predicted diffusing capacity of the lung for carbon monoxide（DLCO%），actual/predicted forced expiratory volume in one second （FEV₁%），and FEV₁/ forced vital capacity （FVC）］，blood gas analysis ［arterial blood diathesis partial pressure of oxygen （PaO₂），partial pressure of carbon dioxide （PaCO₂），and arterial oxygen saturation （SaO₂）］，serum inflammatory factors ［transforming growth factor-β₁ （TGF-β₁），interleukin-4 （IL-4），interleukin-13 （IL-13），interleukin-12 （IL-12），and gamma-interferon （IFN-γ）］，and quality of survival evaluation ［St George's Respiratory Questionnaire （SGRQ） score］. The patients' clinical manifestations were determined at the end of the treatment， and the occurrence of adverse events was recorded. ResultsA total of 53 patients completed the study，comprising 27 in the control group and 26 in the observation group. Upon completion of the treatment period，the control group achieved a total effective rate of 33.33% （9/27），whereas the observation group demonstrated a total effective rate of 53.85% （14/26），which was statistically superior to the control group （χ²=4.034，P<0.05）. After the treatment，the TCM syndrome scores，6MWT，DLCO%，FEV₁%，PaO₂，PaCO₂，TGF-β₁，IL-4，IL-13，IL-12，and IFN-γ in the two groups were all significantly improved （P<0.01）. Compared with those in the control group after treatment at the same period，the TCM syndrome scores，6MWT，PaO₂，and PaCO₂ were significantly improved in the observation group after 60 days and 90 days of medication （P<0.01）. Three months after the end of medication，the SGRQ score in the observation group showed significant improvement when compared to that in the control group （P<0.05），and no severe adverse events were reported during the follow-up period. ConclusionCompound Shenlong decoction can alleviate clinical symptoms such as shortness of breath and wheezing in patients with lung deficiency and collateral stasis syndrome of IPF，enhance exercise tolerance，improve the quality of life，and have certain potential advantages in improving pulmonary function.

Objective To explore the efficacy and safety of evolocumab in elderly patients with high-risk cardiovascular diseases.Methods A total of 153 patients with poor lipid control after conventional statin therapy who were hospitalized in the cardiologic departments in the First,Sec-ond,Sixth and Eighth Medical Centers of Chinese PLA General Hospital from November 2019 to November 2022 were included,and divided into non-elderly group(＜60 years old,46 cases),eld-erly group(60-74 years old,66 case)and very elderly group(≥75 years old,41 cases).They were all given evolocumab treatment according to guidelines.Another 50 over-75-year-old patients with high-risk cardiovascular diseases and poor lipid control who were hospitalized in the above cardiologic departments during the same period were treated with a statin drug combined with ezetimibe,and served as conventional treatment group(control group).The baseline clinical data and the blood indicators at 4th and 12th week after drug administration,and the occurrence of ad-verse drug reactions and major adverse cardiovascular events(MACE)within 12 weeks were com-pared among the groups.Results The levels of LDL-C and TC were significantly decreased in the three evolocumab treatment groups at 4 and 12 weeks after medication when compared with the baseline values(P＜0.05,P＜0.01),but there were no obvious differences in the 2 levels among the 3 groups at 12 weeks(P＞0.05).At the time point,no statistical difference was observed in the incidence of adverse events in the three groups(2.2％vs 3.0％vs 2.4％,P＞0.05).The levels of LDL-C and TC were decreased significantly in the very elderly group and the conventional treatment group at the 12th week when compared with the baseline levels(P＜0.05,P＜0.01),and the LDL-C level at the week was notably lower in the very elderly group than the convention-al treatment group(1.36±0.44 mmol/L vs 1.87±0.56 mmol/L,P＜0.01).But no difference was seen in the incidence of MACE between the 2 groups(12.2％vs 16.0％,P＞0.05),either in sur-vival rate between them(P=0.576).Conclusion For patients of all ages,evolocumab has good short-term efficacy in lipid control,and for those over 75 years old,the drug also shows good effi-cacy and sound safety.

Objective To investigate the anti-fatigue effect of PTR-SeNPs in vivo by measuring the muscle relative length of hindlimb,load-bearing swimming time as well as serum and liver indexes of mice.Methods 48 male C57/BL6 mice were randomly assigned into 4 groups with 12 mice in each group,including vehicle control group(control group),swimming training exercise group(EC group)with vehicle treatment,swimming training exercise with low dose of PTR-SeNPs group(LPTR-SeNPs)and high dose of PTR-SeNPs group(HPTR-SeNPs).The mice were intragastrically administrated with normal saline in both control group and EC group,as well as 2.5 and 10 μmol/(kg·bw)PTR-SeNPs in LHPTR-SeNPs group,respectively,once per day for consecutively 21 days.After swimming training exercise,the muscle structures in the hind limb of mice were examined by magnetic resonance imaging.Furthermore,the burdened swimming time was measured,the serum content of blood lactic acid(BLA),urea nitrogen(BUN),alanine aminotransferase(ALT),glutamic oxalate aminotransferase(AST)and lactate dehydrogenase(LDH),as well as the hepatic level of glycogen(HG),malondialdehyde(MDA)and activity of catalase(CAT)and superoxide dismutase(SOD)were determined.Results Compared with the control group,the serum contents of BLA,BUN,ALT,AST and LDH in EC group(P<0.05 or P<0.01)and hepatic CAT in HPTR-SeNPs group(P<0.01)were significantly increased.The muscle relative length of hind limbs and the burdened swimming time were extended by HPTR-SeNPs markedly(P<0.05).There was no significant difference in MDA level in LHPTR-SeNPs group.Compared with EC group,the burdened swimming time of mice was significantly prolonged(P<0.01),the contents of BLA and BUN were obviously decreased in the HPTR-SeNPs group(P<0.05 or P<0.01),the level of HG was significantly increased in the LHPTR-SeNPs groups(P<0.05 or P<0.01),the serum content of ALT,AST and LDH were markedly decreased in the HPTR-SeNPs group(P<0.05 or P<0.01).Hepatic SOD activity was remarkably increased in LPTR-SeNPs group(P<0.05),the level of CAT was evidently increased(P<0.01)and AST was decreased(P<0.05)in the HPTR-SeNPs group.Conclusion PTR-SeNPs could improve the liver physiological function,increase glycogen storage,reduce the accumulation of metabolites and enhance the body's antioxidant capacity to ameliorate fatigue significantly,which could present the potential to be developed into health care products or drugs.

Objective:To investigate the reasons for the weak expression of RHCE gene in a patient whose mimicking anti-Ce combined with anti-Jkb caused cross-matching non-combination.Methods:ABO,Rh,and Kidd blood group antigens were identified by test tube method and capillary centrifugation.Antibody screening and antibody specificity identification were performed using saline,polybrene and antiglobulin in tri-media association with multispectral cells.RHCE gene sequencing and haploid analysis were performed by multiplex PCR technique and RHCE protein modeling was performed using Swiss-Model.Results:The serum of the patient contained anti-Ce mimicking autoantibodies along with anti-Jkb antibodies.c.48G＞C,c.150C＞T,c.178C＞A,c.201A＞G,c.203A＞G,and c.307C＞T mutations were detected in the RHCE triple-molecule sequencing.A 109 bp insertion sequence was found in intron 2,with fragment loss from intron 5-8.The Rh-group genotype was DCe/DCe,and phenotype was CCDee.Conclusion:Genotyping techniques can assist in deducing the molecular mechanisms of some weakly expressed RhC,c,E,and e in patients'sera to aid in the identification of difficult antibodies and thus ensure the safety of patients'blood transfusion.

Aim To explore the effect of total flavonoid extract(TFE)of Ampelopsis megalophylla on the pro-liferation and apoptosis of human breast cancer cells and its mechanism in autophagy inhibition.Methods For human cervical cancer cell Hela,human lung cancer cell A549,human liver cancer cell SMMC-7721,human breast cancer cell MCF-7,MDA-MB-231 and human normal liver cell L-02,MTT method was used to select sensitive cell lines.The inhibitory effect of TFE combined with autophagy inhibitor 3-methylade-nine(3-MA)on sensitive cell proliferation was detec-ted using MTT assay.The morphological changes of cells were observed using transmission electron micros-copy and Hoechst 33258 single staining method.The changes in cell apoptosis rate were detected using An-nexin V-FITC/PI dual staining method.The expression levels of apoptosis related proteins and pathway pro-teins(death receptor pathway,mitochondrial pathway,endoplasmic reticulum stress pathway)were detected uisng Western blot.The expression of the key protein Cyt-c in mitochondrial pathway was determiend by im-munofluorescence,and the autophagy agonist rapamy-cin was selected for reverse validation.Results TFE could inhibit the proliferation of human breast cancer cells in a concentration-dependent manner,and MCF-7 cells were sensitive cell lines.Compared with the TFE group,the TFE+3-MA group significantly increased the inhibition rate of MCF-7 cells at 24,48,and 72 h(P＜0.01).The number of cells decreased,the gap increased,the number of apoptotic bodies increased,and the apoptosis rate increased(P＜0.01).The ex-pression levels of Bax/Bcl-2(P＜0.01),cleaved-caspase3(P＜0.01),Cyt-c(P＜0.05),FADD,and cleaved-caspase-12 all increased,and the expres-sion of apoptotic protein Cyt-c in nucleus increased.The fluorescence of the TFE+RA group decreased,re-versing the mitochondrial pathway apoptosis induced by TFE.Conclusions TFE can significantly inhibit the proliferation of human breast cancer cells.When inhib-iting autophagy,it may promote the apoptosis of MCF-7 cells through the mitochondrial pathway,and activa-ting autophagy can reverse apoptosis.

Tissue regeneration is an important engineering method for the treatment of oral soft and hard tissue defects.Growth factors,as one of the three elements of tissue regeneration,are a necessary condition for tissue regeneration.Concentrated growth factor(CGF)is a new generation of blood extract prepared by changing the centrifugal speed on the basis of the preparation of platelet-rich plasma(PRP)and platelet-rich fibrin(PRF).It contains abundant growth factors and a fibrin matrix with a three-dimensional network structure,being capable of activating angiogenesis and promoting tissue regeneration and healing.CGF has been widely used in the repair and regeneration of oral soft and hard tissues.This paper introduces the preparation and composition of CGF and reviews the application of CGF in oral implantation and the regeneration of oral bone tissue,periodontal tissue,and dental pulp tissue.

A comprehensive analytical method based on ultra-fast liquid chromatography coupled with triple quadrupole/linear ion trap tandem mass spectrometry(UFLC-QTRAP-MS/MS) was established for simultaneous determination of the content of 45 bioactive constituents including flavonoids, alkaloids, amino acids, phenolic acids, and nucleosides in Epimedium brevicornum. The multiple bioactive constituents in leaves, petioles, stems and rhizomes of E. brevicornum were analyzed. The gradient elution was performed at 30 ℃ in an XBridge~® C_(18) column(4.6 mm×100 mm, 3.5 μm) with 0.4% formic acid aqueous solution-acetonitrile as the mobile phase at a flow rate of 0.8 mL·min~(-1). Single factor experiment and response surface methodology were employed to optimize the extraction conditions. Multivariate statistical analyses including systematic cluster analysis(SCA), principal component analysis(PCA), partial least squares discriminant analysis(PLS-DA), and one-way analysis of variance(One-way ANOVA) were carried out to classify the samples from different parts and identify different constituents. Grey relation analysis(GRA) and entropy weight-TOPSIS analysis were performed to build a multi-index comprehensive evaluation model for different parts of E. brevicornum. The results showed that there was a good relationship between the mass concentrations of 45 constituents and the corresponding peak areas, with the correlation coefficients(r) not less than 0.999 0. The precision, repeatability, and stability of the established method were good for all the target constituents in this study, with the relative standard deviations(RSDs) less than 5.0%(0.62%-4.9%) and the average recovery of 94.51%-105.7%. The above results indicated that the bioactive constituents varied in different parts of E. brevicornum, and the overall quality followed the trend of leaves > petioles > rhizomes > stems. This study verified the rationality of the Chinese Pharmacopoeia(2020 edition) stipulating that the medicinal part of E. brevicornum is the leaf. Moreover, our study indicated that the rhizome had the potential for medicinal development. The established method was accurate and reliable, which can be used to comprehensive evaluate and control the quality of E. brevicornum. This study provides data reference for clarifying the medicinal parts and rationally utilizing the resources of E. brevicornum.
