As an important concept in Chinese medicine theory， "qi sinking" is the inheritance and extension of the thought core of sinking of qi in whole body. This article explored the concept of sinking of pectoral qi， center qi， and kidney qi in the theory of qi sinking， and believed that sinking of pectoral qi， stagnation and sinking of center qi， deficiency and sinking of kidney qi were the core pathogenesis of postoperative injury in malignant tumours. Anchored to the method of reinforcing healthy qi and lifting the sunken， this article recommended to identify pattern and treat by guiding supplement and lifting the sunken. For lung gold impairment， heart yang depletion， and pectoral qi sinking， the treatment is to warm and supplement heart and lung， lift pectoral qi， and restore the respiratory function by modified Shengxian Decoction （升陷汤） plus Guizhi Decoction （桂枝汤）； for spleen depletion and pathways blockage， liver failing to act freely， and center qi stagnation and sinking， the treatment is to warm and supplement center qi， raise yang and lift the sunken， and restore the digestive function by modified Buzhong Yiqi Decoction （补中益气汤）； for source exhausted and essence deficiency， liver qi hiding， and kidney qi deficiency to inward invasion， the treatment is to nourish the kidney and astringe the liver， consolidate the original qi and lift qi， improve the pelvic floor dysfunction， and protect the kidney function by modified Liuwei Dihuang Pill （六味地黄丸） plus Shengma Chaihu Decoction （升麻柴胡汤）. Modification need base on different disease patterns and stages， and new ideas for postoperative traditional Chinese medicine treatment and rehabilitation of malignant tumours were provided.

Thrombosis is a key factor that increases the mortality rate of COVID-19 patients and causes long COVID sequelae. Guanxinning Tablet (GXNT), which is composed of Salvia miltiorrhiza and Ligusticum Chuanxiong, has significant antithrombotic activity, but the similarities and differences between its anti-conventional thrombus and microthrombus induced by COVID-19 remain unclear. In this paper, the main active components, potential targets and mechanisms of GXNT in the treatment of thrombus and microthrombus caused by COVID-19 were preliminarily revealed by using anti-platelet experiments in vitro, network pharmacology analysis, molecular docking technology and molecular biology experiments. The results of platelet aggregation and adhesion experiments in vitro showed that GXNT had significant anti-platelet aggregation and adhesion activities in a dose-dependent manner. Using network pharmacology analysis, it was revealed that salvianolic acid B, tanshinone IIA, caffeic acid and ligustrazine in GXNT could resist thrombus and microthrombus caused by COVID-19 through key targets as the high mobility group box 1 protein (HMGB1), tumor necrosis factor (TNF), interleukin 6 (IL6) and AKT serine/threonine kinase 1 (AKT1). HMGB1 signaling pathway is one of its key common mechanisms. Western blot also indicated that GXNT significantly inhibited the expression of HMGB1 protein in platelets. In summary, this paper explores the similarities and differences between the mechanism of GXNT against conventional thrombus and microthrombus caused by COVID-19 and provides drug reference and theoretical basis for clinical prevention and treatment of long COVID sequelae. The animal experiment has been approved by the Experimental Animal Ethics Committee of Tianjin University of Traditional Chinese Medicine (No. TCM-LAEC2023187g1549).

Objective To explore the current application of high-throughput drug sensitivity(HDS)testing in children with relapsed and refractory acute leukemia(RR-AL)and analyze the feasibility of salvage treatment plans.Methods A retrospective collection of clinical data from children with RR-AL who underwent HDS testing at the Department of Children's Hematology and Oncology of the First Affiliated Hospital of Zhengzhou University from November 2021 to October 2023 was conducted,followed by an analysis of drug sensitivity results and treatment outcomes.Results A total of 17 children with RR-AL underwent HDS testing,including 7 cases of relapsed refractory acute myeloid leukemia and 10 cases of relapsed refractory acute lymphoblastic leukemia.The detection rate of highly sensitive chemotherapy drugs/regimens was 53%(9/17),while the detection rate of moderately sensitive chemotherapy drugs/regimens was 100%(17/17).Among the 17 RR-AL patients with highly and moderately sensitive chemotherapy drugs and regimens,the MOACD regimen(mitoxantrone+vincristine+cytarabine+cyclophosphamide+dexamethasone)accounted for 100%,with the highest inhibition rate for single-agent mitoxantrone(94%,16/17),and the highest inhibition rate for targeted therapy being bortezomib(94%,16/17).Nine patients adjusted their chemotherapy based on HDS testing results,with 4 undergoing hematopoietic stem cell transplantation.Four patients achieved disease-free survival,while 5 died.Eight patients received empirical chemotherapy,with 2 undergoing hematopoietic stem cell transplantation;4 achieved disease-free survival,while 4 died.Conclusions HDS testing can identify highly sensitive drugs/regimens for children with RR-AL,improving the rate of re-remission and creating conditions for subsequent hematopoietic stem cell transplantation.

Objective To evaluate the in vitro effect of combinations of 5 β-lactam antibiotics with different β-lac-tamase inhibitors on the activity of multidrug-resistant Mycobacterium tuberculosis(MDR-TB),and identify the most effective combination of β-lactam antibiotics and β-lactamase inhibitors against MDR-TB.Methods MDR-TB strains collected in Henan Province Antimicrobial Resistance Surveillance Project in 2021 were selected.The mini-mum inhibitory concentrations(MIC)of 5 β-lactam antibiotics or combinations with different β-lactamase inhibitors on clinically isolated MDR-TB strains were measured by MIC detection method,and the blaC mutation of the strains was analyzed by polymerase chain reaction(PCR)and DNA sequencing.Results A total of 105 strains of MDR-TB were included in the analysis.MIC detection results showed that doripenem had the highest antibacterial activity against MDR-TB,with a MIC50 of 16 μg/mL.MIC values of most β-lactam antibiotics decreased significantly after combined with β-lactamase inhibitors.A total of 13.33％(n=14)strains had mutations in blaC gene,mainly 3 nu-cleotide substitution mutations,namely AGT333AGG,AAC638ACC and ATC786ATT.BlaC proteins Ser111 Arg and Asn213Thr enhanced the synergistic effect of clavulanic acid/sulbactam and meropenem on MDR-TB compared with synonymous single-nucleotide mutation.Conclusion The combination of doripenem and sulbactam has the strongest antibacterial activity against MDR-TB.Substitution mutations of BlaC protein Ser111 Arg and Asn213Thr enhances the sensitivity of MDR-TB to meropenem through the synergy with clavulanic acid/sulbactam.

Objective: This meta-analysis aims to refine the understanding of the optimal choice between different cage shapes in transforaminal lumbar interbody fusion (TLIF) by systematically comparing perioperative data, radiological outcomes, clinical results, and complications associated with banana-shaped and straight bullet cages. Methods: A meticulous literature search encompassing PubMed, Embase, Scopus, Web of Science, China Knowledge Network, and Wanfang Data was executed up to October 5, 2023. Inclusion criteria focused on studies comparing banana-shaped and straight bullet cages in TLIF. The quality of included studies was assessed using appropriate tools such as the Newcastle-Ottawa Scale (NOS) for nonrandomized studies. Rigorous evaluations were performed for radiographic outcomes, including disc height (DH), segmental lordosis (SL), lumbar lordosis (LL), subsidence, and fusion rates. Clinical outcomes were meticulously evaluated using visual analogue scale (VAS), Oswestry Disability Index (ODI), and complications. Results: The analysis incorporated 7 studies, involving 573 patients (297 with banana-shaped cages, 276 with straight cages), all with NOS ratings exceeding 5 stars. No statistically significant differences were observed in operative time, blood loss, or hospitalization between the 2 cage shapes. Banana-shaped cages exhibited greater changes in DH (p = 0.001), SL (p = 0.02), and LL (p = 0.01). Despite statistically higher changes in ODI for straight cages (26.33, p < 0.0001), the actual value remained similar to banana-shaped cages (26.15). Both cage types demonstrated similar efficacy in VAS, complication rates, subsidence, and fusion rates. Conclusion Although banana-shaped cages can excel in restoring DH, SL, and LL, straight bullet cages can provide comparable functional improvements, pain relief, and complication rates.
