Objective To evaluate the advantages of powder-liquid double-chamber bag products compared with traditional powder injection. Methods The systematic review method was used to collect the literature on powder-liquid double-chamber bag, extract common evaluation indicators, evaluate the use value of powder-liquid double-chamber bag products, and conduct a comprehensive comparison with traditional powder injection products. Results A total of 23 articles were included in the literature. The effectiveness indicators used for evaluation were the stability of the liquid medicine, the accuracy of the preparation concentration, and the residual amount of the liquid medicine; the safety indicators were the incidence of insoluble particles and the incidence of punctures and scratches. The economic indicators were preparation cost, occupied volume of preparation supplies, waste weight, hospitalization cost and incidence of blood infection. The applicability indicators were preparation time, average occupation of medical staff, packaging weight and storage and transportation volume, environmental adaptability, and ease of waste disposal. Accessibility indicators are the number of manufacturers, raw material supply capacity, and patient affordability. Through the evaluation of literature evidence, it was found that the stability and concentration accuracy of the powder-liquid double-chamber bag were higher than those of the traditional powder injection, and the domestic supply had been achieved. The double-chamber bag method can reduce the infusion reaction and shorten the preparation time of the liquid medicine. Conclusion Compared with traditional powder injectabler products, powder-liquid double-chamber bags have advantages in the dimensions of effectiveness, safety, economy, suitability and innovation, and the accessibility dimension meets the requirements.

BACKGROUND: The achievement of an optimal return to sport (RTS) has remained a key goal after sports-related injuries, with the ongoing debate on the effectiveness of different surgical approaches for anterior cruciate ligament (ACL) rupture. This study aims to assess clinical outcomes and RTS across various surgical methods, such as anatomical single-bundle reconstruction (ASBR), central-axial single-bundle reconstruction (CASBR), and double-bundle reconstruction (DBR). METHODS: A randomized clinical trial was conducted, comprising 191 patients who underwent ACL rupture. These patients were divided into three groups based on the ACL reconstruction techniques they received (ASBR, CASBR, DBR). Over the 2-year follow-up period, the study assessed RTS through four single-hop tests, isokinetic extension tests, and limb asymmetry indices. Postoperative graft status was determined using the signal-to-noise quotient (SNQ), while knee function was evaluated using the International Knee Documentation Committee 2000 (IKDC-2000) score, Lysholm score, Tegner score, and degree of knee laxity. A binary logistic regression model was developed to forecast the factors influencing ideal RTS. RESULTS: DBR (67.63%) and CASBR (58.00%) exhibited higher RTS passing rates compared to ASBR (30.39%; χ2 = 19.57, P <0.05). Quadriceps strength symmetry in the lower limbs was identified as the key determinant of RTS ( χ2 = 17.08, P <0.05). The RTS rate was influenced by SNQs of the graft's tibial site (odds ratio: 0.544) and quadriceps strength of the reconstructed knee joint at 60°/s (odds ratio: 6.346). Notably, the DBR group showed enhanced knee stability, evidenced by superior results in the Lachman test ( χ2 = 13.49, P <0.01), objective IKDC-2000 ( χ2 = 27.02, P = 0.002), and anterior instability test ( χ2 = 9.46, P <0.01). Furthermore, DBR demonstrated superior clinical outcomes based on the Lysholm score (DBR: 89.57 ± 7.72, CASBR: 83.00 ± 12.71, ASBR: 83.21 ± 11.95; F = 10.452, P <0.01) and IKDC-2000 score (DBR: 90.95 ± 7.00, CASBR: 84.64 ± 12.68, ASBR: 83.63 ± 11.41; F = 11.78, P <0.01). CONCLUSION: For patients with ACL rupture, more ideal RTS rate and clinical outcomes were shown in the DBR group than in the ASBR and CASBR groups. Autograft status and quadriceps strength are postively related to RTS. TRIAL REGISTRATION ClinicalTrials.gov (NCT05400460).

Objective To investigate the effect of ligustrazine on spinal cord repair from the perspective of macrophage autophagy and its molecular mechanism in a rat model.Methods A rat model of spinal cord injury was established using Allen's method.Successful modeling was indicated by hindlimb spasm,tail twisting,and Basso,Beattie,and Bresnahan(BBB)score of 0.The rats were divided into 4 groups:sham-operation group,model group,low-dose ligustrazine group,and high-dose ligustrazine group,with 10 rats in each group.The low-dose and high-dose ligustrazine groups were administered ligustrazine(150 mg/kg and 200 mg/kg,respectively)via intraperitoneal injection,while the normal and model groups received an equal volume of normal saline once daily for 28 days.At different time points after surgery,the hindlimb motor function of the rats was assessed using the BBB scale.Hematoxylin-eosin(HE)and Nissl staining were used to observe the histopathological changes in the spinal cord tissue and the morphology of neurons.Enzyme-linked immunosorbent assay(ELISA)was employed to detect the expression levels of superoxide dismutase(SOD)and malondialdehyde(MDA)in the spinal cord tissue.TUNEL staining was used to evaluate the apoptosis status of spinal cord neurons.Protein levels of LC3 I,LC3 Ⅱ,Bax,and Bcl-2 in the spinal cord tissue were detected by Western Blot.Electron microscopy was used to observe the formation of autophagosomes in spinal cord macrophages,and immunofluorescence was used to detect the protein expression of LC3 Ⅱ in spinal cord macrophages.Results Compared with the sham-operation group,the model group exhibited impaired hindlimb function and spinal cord tissue morphology(P<0.05),along with decreased levels of SOD,apoptosis,LC3 Ⅱ/Ⅰ,Bcl-2 protein expression,autophagosome number in macrophages,and LC3 Ⅱ protein expression,as well as increased levels of MDA,Bax,and Bax/Bcl-2 protein expression(P<0.05).Compared with the model group,both the low-dose and high-dose ligustrazine groups showed improved hindlimb function and spinal cord tissue morphology(P<0.05),with increased levels of SOD,apoptosis,LC3 Ⅱ/Ⅰ,Bcl-2 protein expression,autophagosome number in macrophages,and LC3 Ⅱ protein expression,as well as decreased levels of MDA,Bax,and Bax/Bcl-2 protein expression(P<0.05).The intervention effect of ligustrazine was dose-dependent.Conclusion Ligustrazine can effectively repair spinal cord injury in rats,and its molecular mechanism may be related to the activation of autophagy in spinal cord macrophages and the inhibition of neuronal apoptosis.

Recent studies have shown that stress can substantially facilitate breast cancer metastasis,which can be reduced by nonselective β1/β2-adrenergic receptor(β1/β2-AR)blocker.However,several side effects were identified.Thus,it is extremely warranted to explore more effective and better-tolerated β2-AR blocker.Currently,we demonstrated that baicalin(BA),a major bioactive component of Scutellaria bai-calensis Georgi,could significantly attenuate stress hormones especially epinephrine(Epi)-induced breast cancer cell migration and invasion in vitro.Mechanistically,we identified that β2-AR was a direct target of BA via the drug affinity responsive target stability(DARTS)combined with mass spectrum assay,and BA photoaffinity probe with pull-down assay,which was further confirmed by a couple of bio-physical and biochemical assays.Furthermore,we demonstrated that BA could directly bind to the Phe-193 and Phe-289 of β2-AR,subsequently inhibit cyclic adenosine monophosphate-protein kinase A-focal adhesion kinase(cAMP-PKA-FAK)pathway,and thus impede epithelial-mesenchymal transition(EMT),thereby hindering the metastatic progression of the chronic stress coupled with syngeneic and xenograft in vivo orthotopic and tail vein mouse model.These findings firstly identify BA as a potential β2-AR inhibitor in the treatment of stress-induced breast cancer metastasis.
