This study predicts the quality markers(Q-markers) for the cough-relieving and phlegm-expelling effects of Kening Granules based on pharmacodynamics, plasma drug chemistry, network pharmacology, and pharmacokinetics. Strong ammonia solution spray and phenol red secretion assays were employed to evaluate the cough-relieving and phlegm-expelling effects of Kening Granules. Twentysix absorbed prototype components of Kening Granules were identified by ultra high performance liquid chromatography coupled with QExactive Plus quadrupole/Orbitrap high resolution mass spectrometry(UHPLC-Q-Exactive Plus Orbitrap HRMS). Through network pharmacology, 11 potential active components were screened out for the cough-relieving and phlegm-expelling effects of Kening Granules. The 11 components acted on 40 common targets such as IL6, TLR4, and STAT3, which mainly participated in PI3K/Akt, HIF-1, and EGFR signaling pathways. Pharmacokinetic quantitative analysis was performed for 7 prototype components. Three compounds including azelaic acid, caffeic acid, and vanillin were identified as Q-markers for the cough-relieving and phlegm-expelling effects of Kening Granules based on their effectiveness, transmissibility, and measurability. The results of this study are of great significance for clarifying the pharmacological substance basis, optimizing the quality standards, and promoting the clinical application of Kening Granules.

OBJECTIVE: To systematically evaluated clinical efficacy of Kirschner's needle and elastic intramedullary nail fixation in treating proximal humeral fractures in children by Meta-analysis. METHODS: Literature on the treatment of proximal humeral fractures in children with Kirschler needles and elastic intramedullary nails published on Wanfang, VIP, CNKI and China biology medicine (CBM), PubMed, Embase, and Web of Science databases were searched from the establishment of databases to October, 2023. Literature extraction, management and data entry were performed by Endnote X9 and Excel 2019, and Meta-analysis was conducted by RevMan 5.3 software. The operation time, hospital stay, fracture healing time, shoulder joint extension range of motion, disabilities of arm, shoulder and hand(DASH) questionnaire score, Neer score or Constant-Murley score and complications were compared between two groups. RESULTS: A total of 7 literatures were included, 1 was prospective study, 6 were retrospective cohort study. There were 521 children, 264 children in Kirschner wire group and 257 children in elastic intramedullary nail fixation group. The results of Meta analysis showed operation time[WMD=-12.61, 95%CI(-24.89, -0.33), P=0.04], fracture healing time[WMD=-0.26, 95%CI(-0.49, -0.02), P=0.03], total complication rate [OR=6.83, 95%CI(3.33, 14.01), P<0.001], nail tract infection rate[OR=6.77, 95%CI(1.72, 26.69), P=0.006] and displacement fracture rate[OR=3.57, 95%CI(1.35, 9.44), P=0.01] between two groups had statistically differences(P>0.05), while there were no statistically significant difference in comparison of hospital stay, shoulder joint extension range of motion, DASH, Neer score, Constant-Murley score, and incidence of skin irritation between two groups (P>0.05). CONCLUSION Kirschner's needle internal fixation has a short operation time and simple operation, but it has a higher incidence of complications compared with elastic nail internal fixation technique. In terms of efficacy and safety, elastic intramedullary nail fixation is one of the options for the treatment of proximal humeral fractures in children.

OBJECTIVE: To investigate the predictive value of the prognostic nutritional index (PNI) and systemic inflammatory response index (SIRI) for short-term efficacy and prognosis in newly treated patients with peripheral T-cell lymphoma (PTCL). METHODS: The general data, laboratory indicators, disease stage and other clinical data of 91 newly treated PTCL patients admitted to the Affiliated Hospital of Xuzhou Medical University from January 2015 to December 2023 were retrospectively analyzed. The optimal cutoff values for PNI and SIRI were determined using receiver operating characteristic (ROC) curves, and the patients were stratified into groups based on these cutoffs to compare clinical features and short-term efficacy between the different groups. Kaplan-Meier method was used to plot survival curves, and univariate and multivariate analyses were performed to identify the factors affecting overall survival (OS). RESULTS: The optimal cutoff values for PNI and SIRI were 45.30 and 1.74×10⁹/L, respectively. Patients in different PNI groups showed statistically significant differences in age, Ann Arbor stage, lactate dehydrogenase (LDH) level, international prognostic index (IPI), prognostic index for PTCL-not otherwise specified (PIT), pathological subtypes, and complete response (CR) rate (P < 0.05). PTCL patients in different SIRI groups exhibited significant differences in Ann Arbor stage, LDH level, IPI score, PIT score, and CR rate (P < 0.05). Logistic regression analysis showed that age ≥60 years old (OR =2.750), Ann Arbor stage Ⅲ-Ⅳ (OR =5.200), IPI score ≥2 (OR =7.650), low PNI (OR =3.296), and high SIRI (OR =3.130) were independent risk factors affecting treatment efficacy in PTCL patients (P < 0.05). Cox proportional hazards regression model analysis showed that low PNI and elevated β₂-microglobulin (β₂-MG) levels were independent risk factors affecting OS (P < 0.05). CONCLUSION PNI and SIRI have certain application value in evaluating short-term efficacy and prognosis in patients with PTCL. Compared with SIRI, PNI demonstrates greater predictive value for patient prognosis.

Cardiovascular and cerebrovascular diseases, usually result from atherosclerosis, has the highest mortality rate globally. Lipid metabolism disorder is the main cause of atherosclerotic cardiovascular and cerebrovascular diseases, which not only lead to acute diseases such as myocardial infarction, stroke, acute pancreatitis, but also chronic kidney disease. In recent years, the advancement of gene therapy technologies has provided novel means for lipid metabolism study, and has also made it possible to cure patients with congenital lipid metabolism abnormalities. Adeno-associatd virus has a wide host range, high safety, low immunogenicity, and especially the ability of long-term stable expression in vivo, making it the preferred delivery tool for gene therapy of monogenic genetic diseases. Alipogene triprivec, also known as Glybera, was approved by the European Medicines Agency in 2012. It is the first gene therapy drug that uses recombinant AAV1 vector to directly deliver a highly active LPL protein S447X mutant to muscle cells for the treatment of patients with hereditary LPL deficiency. To enhance the targeted transduction efficiency of AAV carriers, recombinantAAV8.TBG.hLDLR utilizes the tissue tropsim of AAV8 to liver, meanwhile utilizes a liver specific thyroxine binding globulin promoter to control gene transcription, thereby achieving liver cell specific high expressionof human low-density lipoprotein receptors (LDLR). In patients with familial hypercholesterolemia,AAV8.TBG.hLDLR treatment effectively lower the level of plasma LDL for a long time, thus preventing the occurrence of atherosclerosis.Proprotein convert subunit kexin 9 (PCSK9) is secreted by liver cells. PCSK9 binds and transports LDLR to lysosomes for degradation, preventing the circulation and regeneration of LDLR, leading to accelerated degradation of LDLR and finally resulting in the accumulation of low-density lipoprotein cholesterol in plasma. Using AAV to deliver Cas9 of Staphylococcus aureus and gRNA targeting the Pcsk9 gene can knock out Pcsk9 in mouse liver, leading to a long-term significant decrease in plasma cholesterol levels in mice. Hepatocyte specific angiopoietin related protein 3 (Angptl3) is an endogenous inhibitor of LPL. Using the AAV9 mediated AncBE4max system and the dCas9 mediated single base gene editing system to introduce early termination codons, the knockout of Angptal3 in liver cells was achieved with an average knockout efficiency of 63.3%. After 2-4 weeks of administration in mice, the Angptl3 protein was completely undetectable in the peripheral blood, and serum triglycerides and total cholesterol decreased by 58% and 61%, respectively. Ring finger containing protein 130 (RNF130) is an E3 ubiquitin ligase. Research has shown that overexpression of RNF130 using AAV2/8 leads to ubiquitination degradation and redistribution of LDLR on the cell membrane, significantly reducing LDLR expression on liver cells and increasing plasma LDLC levels, while knocking out Rnf130 gene using the AAV-CRISPR system results in the opposite effect. This AAV mediated RNF130 function study proves that RNF130 is a posttranslational regulatory protein of LDLR and plays an important role in the regulation of serum LDLC. As mentioned above, recently, various lipid-lowering gene therapy drugs carried by different serotypes of adeno-associated virus have been applied in clinic or are undergoing clinical trials, and adeno-associated virus has emerging to be an important tool for lipid metabolism research.This article reviews the new progress of adeno-associated virus vectors in lipid metabolism study and lipid-lowering gene therapy.

In order to study the compounds from Glechoma longituba (Nakai) Kupr. and explore the substance bases of its dissipating blood stasis, MCI, silica gel, Sephadex LH-20, ODS column chromatography and preparative thin layer chromatography were used to isolate and purify the compounds. The structures were identified by MS, 1D NMR, and 2D NMR spectra analysis, etc. Eight triterpenoids were isolated from dichloromethane fraction of ethanol extract from G. longituba and identified as 2α,3α,16β-trihydroxy-13α,27-cyclours-11-en-28-oic acid (1), 28-norurs-12-ene-3β,17β-diol (2), 28-norolean-12-ene-3β,17β-diol (3), oleanonic acid (4), 3β,13β-dihydroxyurs-11-en-28-oic acid (5), uvaol (6), oleanolic acid (7), ursolic acid (8). Compound 1 is a new hexacyclic triterpene with 13α,27-cyclopropane structure, named euscaphic acid H; compounds 2 and 3 were isolated from Lamiaceae for the first time while compounds 4 and 5 were isolated from this genus. The in vitro anticoagulant activity of triterpenoids was evaluated by four coagulation indexes (activated partial thromboplastin time, APTT; thrombin time, TT; prothrombin time, PT; fibrinogen, FIB). Among them, compounds 1 and 6 showed obvious anticoagulant effects.

OBJECTIVE To investigate whether the microRNA-222(miRNA-222) carried by plasma exosomes can serve as an early warning marker for cognitive impairment induced by shRNA-PCSK9. METHODS The high-fat diet(HFD) was used to prepare a hypercholesterolemic mouse model group. The model group mice were divided into HFD-shRNA control group and HFD-shRNA-PCSK9 group. The shRNA-PCSK9 was constructed, injected intravenously into the body, and the expression of PCSK9 mRNA was detected by real-time PCR(RT-PCR). Tau protein and phosphorylation in brain tissue were observed by immunohistochemistry (IHC). Western blotting was used to detect Tau protein and P-Tau protein. Serum amyloid Aβ1-42Ab levels were determined by ELISA. The kits extracted plasma exosomes step by step, identify the exosome morphology by negative staining electron microscopy, and determined the size of exosomes by NTA technology. RT-PCR technique was used to detect the expression level of miRNA-222 carried in plasma exosomes. RESULTS The model mouse were prepared by feeding HFD for 13 weeks, whose total cholesterol(TC) and low-density lipoprotein(LDL-C) contents in serum were significantly increased. At the same time, the expression of PCSK9 mRNA in the brain tissue of model group was significantly increased. After shRNA-PCSK9 lentivirus interference, PCSK9 mRNA expression was inhibited, and IHC observed that shRNA-PCSK9 induced abnormal expression and hyperphosphorylation of Tau protein in brain tissue, indicating that the pathological changes of neurofibrillary tangles had occurred. However, at this time, serum Aβ1-42Ab had not been significantly increased, and it had not yet been of significance for the diagnosis of cognitive impairment. The miRNA in plasma exosomes was extracted, and RT-PCR results showed that the expression of miRNA-222 carried in the exosomes of the HFD-shRNA-PCSK9 group was significantly lower than that of the HFD-shRNA control group. CONCLUSION Plasma exosomes carried miRNA-222 provides an early warning marker for shRNA-PCSK9- induced cognitive impairment.
