ObjectiveTo study the correlations between traditional Chinese medicine （TCM） syndromes and lipid metabolism in children with Wilson disease （WD）. MethodsClinical data and lipid metabolism indicators ［total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein cholesterol （LDL-C）， high-density lipoprotein cholesterol （HDL-C）， apolipoprotein A1 （ApoA1）， apolipoprotein B （ApoB）， and lipoprotein a （Lpa）］ were retrospectively collected from 341 children with WD. The clinical data were compared among WD children with different syndromes， and the correlations between TCM syndromes and lipid metabolism in children with WD were analyzed. Least absolute shrinkage and selection operator （LASSO） regression was used for variable screening， and unordered multinomial Logistic regression was employed to analyze the effects of lipid metabolism indicators on TCM syndromes. ResultsThe 341 children with WD included 121 （35.5%） children with the dampness-heat accumulation syndrome， 103 （30.2%） children with the liver-kidney Yin deficiency syndrome， 68 children with the combined phlegm and stasis syndrome， 29 children with the spleen-kidney Yang deficiency syndrome， and 20 children with the liver qi stagnation syndrome. The liver-kidney Yin deficiency syndrome， combined phlegm and stasis syndrome， and spleen-kidney Yang deficiency syndrome had correlations with the levels of lipid metabolism indicators （P<0.05）. Lipid metabolism abnormalities occurred in 232 （68.0%） children， including hypertriglyceridemia （108）， hypercholesterolemia （23）， mixed hyperlipidemia （67）， lipoprotein a-hyperlipoproteinemia （12）， and hypo-HDL-cholesterolemia （22）. The percentages of hypertriglyceridemia and hypo-HDL-cholesterolemia varied among children with different TCM syndromes （P<0.05）. Correlations existed for the liver-kidney Yin deficiency syndrome with TG， TC， and HDL-C， the combined phlegm and stasis syndrome with TG， the spleen-kidney Yang deficiency syndrome with TG， TC， and LDL-C， and the liver Qi stagnation syndrome with TC and LDL-C （P<0.05， P<0.01）. ConclusionThe TCM syndromes of children with WD are dominated by the dampness-heat accumulation syndrome and the liver-kidney Yin deficiency syndrome， and dyslipidemia in the children with WD is dominated by hypertriglyceridemia and mixed hyperlipidemia. There are different correlations between TCM syndromes and lipid metabolism indicators， among which TG， TC， LDL-C， and HDL-C could assist in identifying TCM syndromes in children with WD.

Aim To establish a stable hepatic stellate cell ( HSC ) -specific G protein-coupled receptor kinase 2 ( GRK2 ) knockout mice and provide the important animal model for further studying the biological function of GRK2 in HSC. Methods The loxP-labeled Grk2 gene mouse (Grk2

The objective of this study was to analyze the effects on cell viability, apoptosis, and cell cycle of non-small cell lung cancer (NSCLC) A549 cells after intervention with Agrimonia pilosa (AP) and investigate Agrimonia pilosa anti-tumor activity in vitro. Meanwhile, liquid chromatography mass spectrometry (LC-MS) metabolomics technology was used to analyze the changes of cellular metabolites and metabolic pathways. The results of this study will provide a theoretical and experimental basis for investigating the mechanism of the effect of Agrimonia pilosa on non-small cell lung cancer A549 cells. The results showed that the cell nucleus of A549 cells crumpled and apoptosis occurred with the increase of drug concentration. The survival rate of the cells decreased, and the inhibition rate reached 21.5% and 91.74% under the low and high dose conditions, respectively. Lactate dehydrogenase (LDH) content increased (P < 0.05). Metabolomics results showed significant differences in metabolism between groups, thirty-three distinct metabolites including LysoPC(24:0/0:0), LysoPC(17:0/0:0) and PC(O-40:5) were deduced. The pathway enrichment showed that the Agrimonia pilosa plays an anti-tumor role mainly by regulating the metabolism of glycerophosphate and purine in A549 cells, in which the effect on glycerophosphate metabolism pathway was most significant. The results of combined pharmacodynamics suggested that Agrimonia pilosa might induce apoptosis and inhibit the growth of A549 cells by regulating LysoPC(24:0/0:0), LysoPC(17:0/0:0) and PC(O-40:5) metabolites in A549 cells.

Objective To explore the efficacy and safety of recombinant human anti-severe acute respiratory syn-drome coronavirus 2(anti-SARS-CoV-2)monoclonal antibody injection(F61 injection)in the treatment of patients with coronavirus disease 2019(COVID-19)combined with renal damage.Methods Patients with COVID-19 and renal damage who visited the PLA General Hospital from January to February 2023 were selected.Subjects were randomly divided into two groups.Control group was treated with conventional anti-COVID-19 therapy,while trial group was treated with conventional anti-COVID-19 therapy combined with F61 injection.A 15-day follow-up was conducted after drug administration.Clinical symptoms,laboratory tests,electrocardiogram,and chest CT of pa-tients were performed to analyze the efficacy and safety of F61 injection.Results Twelve subjects(7 in trial group and 5 in control group)were included in study.Neither group had any clinical progression or death cases.The ave-rage time for negative conversion of nucleic acid of SARS-CoV-2 in control group and trial group were 3.2 days and 1.57 days(P=0.046),respectively.The scores of COVID-19 related target symptom in the trial group on the 3rd and 5th day after medication were both lower than those of the control group(both P＜0.05).According to the clinical staging and World Health Organization 10-point graded disease progression scale,both groups of subjects improved but didn't show statistical differences(P＞0.05).For safety,trial group didn't present any infusion-re-lated adverse event.Subjects in both groups demonstrated varying degrees of elevated blood glucose,elevated urine glucose,elevated urobilinogen,positive urine casts,and cardiac arrhythmia,but the differences were not statistica-lly significant(all P＞0.05).Conclusion F61 injection has initially demonstrated safety and clinical benefit in trea-ting patients with COVID-19 combined with renal damage.As the domestically produced drug,it has good clinical accessibility and may provide more options for clinical practice.

Objective Recombinase-aided polymerase chain reaction(RAP)is a sensitive,single-tube,two-stage nucleic acid amplification method.This study aimed to develop an assay that can be used for the early diagnosis of three types of bacteremia caused by Staphylococcus aureus(SA),Pseudomonas aeruginosa(PA),and Acinetobacter baumannii(AB)in the bloodstream based on recombinant human mannan-binding lectin protein(M1 protein)-conjugated magnetic bead(M1 bead)enrichment of pathogens combined with RAP. Methods Recombinant plasmids were used to evaluate the assay sensitivity.Common blood influenza bacteria were used for the specific detection.Simulated and clinical plasma samples were enriched with M1 beads and then subjected to multiple recombinase-aided PCR(M-RAP)and quantitative PCR(qPCR)assays.Kappa analysis was used to evaluate the consistency between the two assays. Results The M-RAP method had sensitivity rates of 1,10,and 1 copies/μL for the detection of SA,PA,and AB plasmids,respectively,without cross-reaction to other bacterial species.The M-RAP assay obtained results for<10 CFU/mL pathogens in the blood within 4 h,with higher sensitivity than qPCR.M-RAP and qPCR for SA,PA,and AB yielded Kappa values of 0.839,0.815,and 0.856,respectively(P<0.05). Conclusion An M-RAP assay for SA,PA,and AB in blood samples utilizing M1 bead enrichment has been developed and can be potentially used for the early detection of bacteremia.

Objective: Danshensu, a phenylpropanoid compound, is derived from the dry root and rhizome of Danshen (Salvia miltiorrhiza), a traditional Chinese medicinal herb. Evidence suggests that danshensu protects isolated rat hearts against ischemia/reperfusion injury by activating the protein kinase B (Akt)/extracellular signal-regulated kinase (ERK) pathway or by inhibiting autophagy and apoptosis through the activation of mammalian target of rapamycin (mTOR) signaling. Furthermore, danshensu promotes the postischemic regeneration of brain cells by upregulating the expression of brain-derived neurotrophic factor (BDNF) in the peri-infarct region. However, basic and clinical studies are needed to investigate the antidepressant effects danshensu and determine whether brain mTOR signaling and BDNF activation mediate these effects. The aforementioned need prompted us to conduct the present study. Methods: Using a C57BL/6 mouse model, we investigated the antidepressant-like effects of danshensu and the mechanisms that mediate these effects. To elucidate the mechanisms, we analyzed the roles of Akt/ERK–mTOR signaling and BDNF activation in mediating the antidepressant-like effects of danshensu. Results: Danshensu exerted its antidepressant-like effects by activating the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) of Akt/ERK–mTOR signaling and promoting BDNF release. Treatment with danshensu increased the level of glutamate receptor 1 phosphorylation at the protein kinase A site. Conclusion Our study may be the first to demonstrate that the antidepressant effects of danshensu are dependent on the activation of the AMPAR–mTOR signaling pathway, are correlated with the elevation of BDNF level, and facilitate the insertion of AMPAR into the postsynaptic membrane. This study also pioneers in unveiling the potential of danshensu against depressive disorders.

Purpose::Our previous study in 2009 concluded that glutamine may shorten the length of hospital stay (LOS) in patients with severe burns. Recent large-scale studies have suggested a decline in the effectiveness of glutamine in treating patients with severe burns over the last decade. Therefore, we conducted this systematic review and meta-analysis to update the status of glutamine uses in patients with severe burns.Methods::We retrieved related literature prior to December 2022 from the PubMed, Web of Science, Cochrane Library, Embase, SinoMed, Wanfang, and CNKI databases. Terms such as glutamine, enteral and burn were linked for searching. Adults patients with severe burns were included and non-randomized controlled trials were excluded. Data from studies that compared enteral glutamine for severe burns with a control group were extracted. The primary outcomes of mortality and infectious morbidities were pooled and analyzed. The modified Jadad scale and Cochrane collaboration's tool were used to assess the risk of bias in RCTs, and the Review Manager 5.4 was used to pool and analyze the data.Results::Six randomized controlled trials involving 1398 patients were included in the analysis. There were no significant differences in overall mortality (risk ratio ( RR) =0.37; 95% confidence interval ( CI): 0.06 -2.37; p =0.300) or infectious morbidities ( RR =0.73; 95% CI: 0.41 -1.31; p =0.290). The incidence of multiple organ dysfunction syndrome was similar between the 2 groups ( RR =0.27; 95% CI: 0.03 -2.24; p =0.220). The LOS (mean difference (MD) =-8.97; 95% CI: -15.22 to -2.71; p =0.005) and LOS/total burn surface area (MD =-0.27; 95% CI: -0.54 to 0.00; p =0.050) decreased in the enteral glutamine group. The incidence of wound infection was significantly reduced ( RR =0.42; 95% CI: 0.16 -1.06; p =0.070). Conclusion::Compared to the control group, enteral glutamine administration may not improve the mortality, although it may be associated with a shorter LOS, a lower LOS/total burn surface area ratio, and may reduce the risk of wound infection in patients with severe burns.

Objective To explore the diagnostic value of serum neuronal Per-Arnt-Sim domain protein 4(NPASDP-4)and myelin basic protein(MBP)expression in patients with Parkinson's disease in relation to cognitive impairment(CI)and severity.Methods Selected and 138 Parkinson's disease patients admitted to the 909th Hospital of the Joint Logistics Support Force of the People's Liberation Army of China as the Parkinson's disease group,and 69 healthy people in the physical examination center of the hospital were in the healthy control group.Patients with Parkinson's disease were divided into normal cognitive function group(n=55),mild CI group(n=51)and dementia group(n=32)according to whether CI occurred and its severity.General data of subjects was collected,the serum levels of NPASDP-4 and MBP were detected by ELISA,correlation analysis was adopted by Spearman rank correlation or Pearson linear correlation,diagnostic value was analyzed by ROC curve,and influencing factors were analyzed by multivariate Logistic regression.Results Compared with the healthy control group,the levels of serum NPASDP-4(6.75±0.48 ng/ml vs 2.38±0.31 ng/ml)and MBP(8.34±0.65 μg/L vs 3.54±0.42 μg/L)in the Parkinson's disease group were increased with statistical significance(r=68.751,55.761,all P＜0.05).There were significant differences in H-Y stage among the normal cognitive function group,mild CI group and dementia group(x2=7.788,P＜0.05).Compared with the group with normal cognitive function(47.92±11.63 score),the mild CI group(50.78±13.69 score)and the dementia group(41.95±10.36 score)showed an increase in UPDRS-Ⅲ scores,and the differences were statistically significant(H=6.672,all P＜0.05).In normal cognitive function group,mild CI group and dementia group,the course of disease,and serum NPASDP-4(5.89±0.40,6.83±0.55,8.12±0.54 ng/ml)and MBP(6.65±0.56,8.94±0.69,10.27±0.70μg/L)levels were significantly increased(H=207.950,355.594,allP＜0.05),while MMSE score(28.47±0.94,24.51±1.35,17.09±2.57 score),MoCA score(27.45±1.03,20.18±1.92,11.75±2.53 score)and GPCOG total score(13.47±0.69,10.25±1.04,8.97±0.82 score)were significantly decreased,and the differences were statistically significant(H=515.005,775.933,327.584,all P＜0.05),respectively.The serum levels of NPASDP-4 and MBP in Parkinson's disease patients were significantly positively correlated with the course of disease(r=0.316,0.358),H-Y stage(r=0.345,0.384)and UPDRS-Ⅲ score(r=0.371,0.396),and significantly negatively correlated with MMSE score(r=-0.468,-0.517),MoCA score(r=-0.504,-0.569)and GPCOG total score(r=-0.527,-0.538)(all P＜0.05),respectivey.The areas under the curve(AUC)of the serum levels of NPASDP-4,MBP and their combination in diagnosing of Parkinson's disease were 0.850,0.930 and 0.960,respectively.The AUC of the serum levels of NPASDP-4 and MBP and their combination in diagnosing the severity of CI in patients with Parkinson's disease were 0.866,0.803 and 0.933,respectively.H-Y stage metaphase[OR(95％CI):4.725(1.742～12.814)],H-Y stage advanced[OR(95％CI):5.083(1.919～13.464)],UPDRS-Ⅲ score[OR(95％CI):3.257(1.464～7.246)],NPASDP-4[OR(95％CI):5.324(1.516～18.701)]and MBP[OR(95％CI):5.769(2.459～13.533)]were the influential factors for CI in patients with Parkinson's disease(all P＜0.05).NPASDP-4[OR(95％CI):4.768(2.382～9.543)]and MBP[OR(95％CI);5.846(3.141～10.882)]were the influential factors for the severity of CI in patients with Parkinson's disease(all P＜0.05).Conclusion The serum levels of NPASDP-4 and MBP in patients with Parkinson's disease were high,and they were closely related to CI and its severity,which may have certain clinical diagnostic value.

Neck dissection(ND)is one of the main treatment methods for oral and maxillofacial malignancies.Although ND type is in con-stant improvement,but intraoperative peal-pull-push injury of the accessory nerve,muscle,muscle membrane,fascia and ligament induced shoulder syndrome(SS)is still a common postoperative complication,combined with the influence of radiochemotherapy,not only can cause pain,stiffness,numbness,limited dysfunction of shoulder neck and arm,but also may have serious impact on patient's life quality and phys-ical and mental health.At present,there is still a lack of a systematic evaluation and rehabilitation management program for postoperative SS of oral and maxillofacial malignant tumors.Based on the previous clinical practice and the current available evidence,refer to the relevant lit-erature at home and abroad,the experts in the field of maxillofacial tumor surgery and rehabilitation were invited to discuss,modify and reach a consenusus on the etiology,assessment diagnosis,differential diagnosis,rehabilitation strategy and prevention of SS,in order to provide clinical reference.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
