OBJECTIVE: To investigate the early clinical efficacy of single-position O-arm navigation-assisted oblique lateral interbody fusion(OLIF) combined with minimally invasive percutaneous pedicle screw fixation(PPS) in the treatment of lumbar spondylolisthesis. METHODS: A retrospective analysis was conducted on 22 patients with lumbar spondylolisthesis who underwent OLIF-PPS surgery including 11 males and 11 females with a mean age of (64.6±1.5) years old ranging from 49 to 80 years old between April 2021 and June 2023. All patients presented with lumbosacral pain, lower limb radiating pain, numbness, and had poor responses to conservative treatment. Surgical time, intraoperative blood loss, hospital stay, and postoperative complications were recorded. Clinical outcomes were evaluated using the visual analogue scale(VAS) and Oswestry disability index(ODI) preoperatively at 3 days after operation and the final follow-up. Standing lumbar anteroposterior and lateral X-rays were performed to measure disc height(DH), slippage degree, vertebral reduction rate, pedicle screw accuracy, and cage subsidence. RESULTS: All surgeries were successfully completed with a mean follow-up of (27.1±2.2) months (range 18 to 36 months). The mean surgical time was (76.1±12.2) min (range 60 to 93 min), intraoperative blood loss was (86.3±32.2) ml (range 40 to 113 ml), and hospital stay was (7.1±1.2) days. Postoperative VAS significantly improved from (7.2±0.7) preoperatively to (2.3±0.5) at 3 days after operation and (1.7±0.2) at the final follow-up (P<0.05). ODI decreased from (68.5±7.2)% preoperatively to (30.3±3.1)% at 3 days after operation and (16.6±1.6)% at the final follow-up (P<0.05). DH increased from (8.5±1.7) mm preoperatively to (18.1±1.4) mm at 3 days after operation and (17.2±1.1) mm at the final follow-up (P<0.05). Slippage degree improved from (24.1±4.6)% preoperatively to (10.3±4.2)% at 3 days after operation and (10.1±3.2)% at the final follow-up (P<0.05). A total of 88 pedicle screws were implanted with an excellent rate of 98% (86/88). Complications included transient left hip flexion weakness (2 cases) and left anteromedial thigh pain (1 case), all resolved during follow-up. No incision hematoma, infection, screw loosening, or cage subsidence occurred. CONCLUSION Single-position O-arm navigation-assisted OLIF combined with PPS demonstrates satisfactory early clinical efficacy for lumbar spondylolisthesis, with advantages including minimal invasiveness, significant pain relief, effective vertebral reduction, and low complication rates.

OBJECTIVE: Evaluate the clinical application effect of low-field infant MRI. METHODS: Using literature review, expert consultation, and two rounds of Delphi to determine the evaluation index system. Then retrospectively analyze and compare the data of low-field infant MRI and high-field MRI from January 2023 to December 2024. RESULTS: There is a certain gap between low-field infant MRI and high-field MRI in terms of signal-to-noise ratio, image uniformity, software system reliability, scanning time, user interface friendliness and image result consistency. However, there was no difference in terms of spatial resolution and image quality. The noise, hardware system reliability, mean time between failure and the rate of examination completed without sedation are better than that of high-field MRI. CONCLUSION Low-field infant MRI meets needs of clinical diagnostic and has stable performance. It can be used as a routine screening tool for brain diseases near the bed.

A new method for simultaneous determination of 23 kinds of per-and polyfluoroalkyl substances(PFASs)(13 kinds of perfluoro carboxylic acids,4 kinds of perfluoro sulfonic acids,and 6 kinds of new substitutes)in plant leaf tissue by ultra-high performance liquid chromatography-tandem mass spectrometry(UHPLC-MS/MS)using automatic online solid phase extraction(SPE)to remove the matrix interference components in plant crude extracts was developed.The plant leaf samples were extracted twice with 1%formic acid-methanol solution,then evaporated to dry,redissolved with 70%methanol solution,and directly injected for analysis.After 23 kinds of target PFASs were purified automatically by online SPE with a WAX column,the six-way valve was switched to rinse PFASs onto an alkaline mobile phase system-compatible C18 analytical column.Then,the 23 kinds of target PFASs were separated within 16 min by gradient elution using a binary mobile phase system of methanol/water(Containing 0.4%ammonium hydroxide).Tandem mass spectrometry was performed in multiple reaction monitoring(MRM)mode for online detection of various PFASs,and quantification was carried out by internal standard method.The results of the method validation showed that satisfactory average recoveries of 23 kinds of PFASs in plant leaf samples(64.2%-125.5%),precision(relative standard deviations(RSDs)of 0.7%-12.8%),linearity(R2＞0.990),and sensitivity(the detection limits(S/N=3)were in the range of 0.02-0.50 μg/kg)were achieved.Finally,this method was used to detect PFASs in the marine green tide algae(Enteromorpha prolifera)and several tree leaves,and a total of 6 kinds of PFASs were detected,in which PFBA was the main contaminant.Compared with the reported offline SPE methods,the proposed online SPE technique significantly simplified the sample pretreatment process and provided an automatic,simple,and environment-friendly method for the routine monitoring of legacy and emerging PFASs in plant tissues.

Zuoguiwan， one of the classic formulas of traditional Chinese medicine （TCM）， has the effects of nourishing genuine Yin， supplementing essence， and replenishing marrow， and it is widely used in the clinical treatment of diseases caused by congenital essence deficiency. This article systematically reviewed the ancient books involving congenital deficiency and the modern research reports on the treatment of congenital deficiency with Zuoguiwan. From the formulation principle of Zuoguiwan and the TCM concept of congenital deficiency， this article discussed the theoretical basis of treating congenital deficiency with Zuoguiwan based on the modern research results. Ancient physicians have discovered that the deficiency of parents can lead to abnormal physical development and weakness of the offspring. ZHANG Jingyue divided congenital essence Qi into genuine Yin and primordial Yang and formulated Zuoguiwan based on the principle of Yin-Yang mutual assistance for supplementing congenital genuine Yin. Experimental studies have shown that Zuoguiwan can up-regulate the expression of connexin 43 （Cx43） protein and improve gap junction intercellular communication （GJIC） function to promote osteogenic differentiation and maturation of bone marrow mesenchymal stem cells and ameliorate abnormal bone development caused by congenital essence deficiency. Zuoguiwan can enhance the expression and activity of Reelin to ameliorate abnormal brain development. It can upregulate the expression of Cx43 protein to intervene in the phosphatidylinositol 3 kinase/protein kinase B （PI3K/Akt） pathway， thus repairing the reproductive functions. Zuiguiwan can promote the development and maturation of T cells and activate the Wnt/β-catenin signaling pathway in the thymus to improve immune functions. In addition， it can promote the expression of β-catenin and inhibit the expression of microtubule-associated proteins 1 light chain 3 （LC3） to attenuate skin dysfunctions. Moreover， Zuoguiwan can guide the differentiation of stem cells via the correlation between essence and vitality in TCM. Zuoguiwan has demonstrated significant therapeutic effects on some diseases in the pediatric， andrological， gynecological， geriatric， internal medicine， orthopedic and skin disease departments. On the basis of the results of experiments and clinical applications， this paper analyzes the specific connotation of congenital deficiency proposes that congenital deficiency should be subdivided into the four aspects of essence， Qi， Yin， and Yang. Congenital essence deficiency as the deficiency of genuine Yin can lead to deficiency of kidney essence in the offspring and dysfunction of kidney storing essence. Pharmacological studies have discovered that Cuscutae Semen， Lycii Fructus， and Achyranthis Bidentatae Radix in Zuoguiwan contain active components such as quercetin and kaempferol， which act on the targets such as recombinant prostaglandin endoperoxide synthase 2 （PTGS2）， interleukin-6 （IL-6）， mitogen-activated protein kinases （MAPK14）， tumor necrosis factor （TNF）， TP53， Vascular permeability factor A （VEGFA）， and albumin （ALB） to play a role in reproductive system development and hormone responses. Zuoguiwan has unique advantages over Liuwei Dihuangwan in nourishing congenital genuine Yin in the kidney and can achieve better therapeutic effects on the syndromes and diseases caused by congenital essence deficiency. This review is expected to enrich the knowledge about the efficacy and clinical application of Zuoguiwan， provide new perspectives and methods for the prevention and treatment of congenital deficiency and congenital essence deficiency， and give insights into the application of Zuoguiwan in modern healthcare， especially in the nurturing of offspring.

Human brain banks use a standardized protocol to collect,process and store post-mortem human brains and related tissues,along with relevant clinical information,and to provide the tissue samples and data as a resource to foster neuroscience research according to a standardized operating protocols(SOP).Human brain bank serves as the foundation for neuroscience research and the diagnosis of neurological disorders,highlighting the crucial rule of ensuring the consistency of standardized quality for brain tissue samples.The first version of SOP in 2017 was published by the China Human Brain Bank Consortium.As members increases from different regions in China,a revised SOP was drafted by experts from the China Human Brain Bank Consortium to meet the growing demands for neuroscience research.The revised SOP places a strong emphasis on ethical standards,incorporates neuropathological evaluation of brain regions,and provides clarity on spinal cord sampling and pathological assessment.Notable enhancements in this updated version of the SOP include reinforced ethical guidelines,inclusion of matching controls in recruitment,and expansion of brain regions to be sampled for neuropathological evaluation.

Nanomaterial matrices have unique advantages in small molecule analysis by matrix-assisted laser desorption ionization mass spectrometry(MALDI-MS).On the basis of comparing different surfactants,a method for pre-coating nanocarbon sodium dodecyl sulfate(SDS)composite matrix was established,which could alleviate the issue of aggregation of nanocarbon particles as a matrix.The experimental results showed that the nanocarbon-SDS composite pre-coated matrix effectively suppressed the background ion peak of the nano matrix,significantly improved the MS peak intensity and signal-to-noise ratio of the tested substance.Under the optimal conditions,cholesterol,1,2-dipalmitoyl-sn-glyceryl-3-phosphorylcholine(DPPC),and triglyceride standards were analyzed,with intra-point repeatability(RSD)of MS peak intensity≤5%and inter-point repeatability≤7%.As to measurement of cyclic adenosine monophosphate and DPPC samples in the range of 0.05?1.0 mg/mL,linear correlation coefficient(R2)between peak intensity and concentration was greater than 0.993,indicating good quantitative analysis potential.The nanocarbon-SDS composite pre-coating matrix was used for MALDI-MS imaging of pig brain tissue,and the differences in component distribution between pig brain white matter and gray matter were observed,demonstrating the potential of nanocarbon-SDS composite pre-coating matrix for MALDI-MS imaging.

OBJECTIVE To explore the effect of Huangqin decoction on improving peritubular fat inflammatory microenvironment and protecting vascular endothelial function in obese hypertensive rats by regulating the NEK7-NLRP3/IL-1β inflammatory axis.METHODS Fifty 4-week-old male Wistar rats were selected,10 of which were randomly selected as the control group,and the oth-er 40 were fed a high-salt and high-fat diet to establish an obese hypertension model.The rats with successful modeling(20 rats)were randomly divided into the model group,normal-dose Huangqin decoction group,high-dose Huangqin decoction group,and IL-1β in-hibitor group,with 5 rats in each group.From the 12th week,the normal-dose group was gavaged with Huangqin decoction 2.835 g·kg-1,the high-dose group was gavaged with Huangqin decoction 5.67 g·kg-1,and the IL-1β inhibitor group was intraper-itoneally injected with 1.5 mg·kg-1 AS101,3 times a week,for 8 weeks.The rats were weighed and blood was collected 12 h after the last administration,and the thoracic aorta and perivascular fat tissue were isolated.Serum inflammatory factors were detected,patho-logical changes were observed,eNOS expression was detected by immunofluorescence,and NEK7,NLRP3,Caspase-1,ASC,and IL-1β expression levels were detected by Western blot and qPCR.RESULTS The rats in the model group had a significant increase in body weight,an increase in the area of peritubular fat lipid droplets,and severe endothelial injury;systolic blood pressure,diastolic blood pressure,serum IL-1β,IL-6,and TNF-α were significantly elevated in the model group,and the expression of eNOS was sig-nificantly reduced,and the expression levels of NEK7,NLRP3,Caspase-1,ASC,and IL-1β proteins and mRNAs were significantly elevated.Compared with the model group,rats in the Huangqin decoction and IL-1β inhibitor groups had lower body weights,reduced endothelial damage,lower systolic and diastolic blood pressures,lower serum IL-1β,IL-6,and TNF-α,and higher eNOS expression.NEK7,NLRP3,Caspase-1,ASC and IL-1β protein expression was significantly reduced in the high dose group of Huan-gqin decoction and the IL-1β inhibitor group.In addition,Huangqin decoction protected the endothelial function of obese hypertensive vessels in a dose-dependent manner,with the effect being more pronounced in the high-dose group.CONCLUSION Huangqin de-coction can improve the inflammatory microenvironment of perivascular fat and protect the vascular endothelial function in obese hyper-tension by regulating the NEK7-NLRP3/IL-1β inflammatory axis.

OBJECTIVE: To investigate the clinical effect of aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban for lower extremity venous thrombosis after total knee arthroplasty and the influence on hypercoagulation. METHODS: Seventy-three patients of knee osteoarthritis with lower extremity venous thrombosis after total knee arthroplasty (KOA) were randomly divided into an observation group (37 cases, 2 cases dropped off) and a control group (36 cases, 1 case dropped off). The patients in the control group took orally rivaroxaban tablets, 10 mg a time, once a day. On the basis of the treatment as the control group, the aconite-isolated moxibustion was applied to Yongquan (KI 1) for the patients of the observation group, once daily and 3 moxa cones were used in each treatment. The duration of treatment was 14 days in both groups. Before treatment and 14 days into treatment, the ultrasonic B test was adopted to determine the conditions of lower extremity venous thrombosis in the two groups. Before treatment, 7 and 14 days into treatment, the coagulation indexes (platelet [PLT], prothrombin time [PT], activated partial prothrombin time [APTT], fibrinogen [Fib] and D-dimer[D-D]), the blood flow velocity of the deep femoral vein and the circumference of the affected side were compared between the two groups separately, and the clinical effect was evaluated. RESULTS: Fourteen days into treatment, the venous thrombosis of the lower extremity was relieved in both groups (P<0.05), and that of the observation group was better than the control group (P<0.05). Seven days into treatment, the blood flow velocity of the deep femoral vein was increased compared with that before treatment in the observation group (P<0.05), and the blood flow rate in the observation group was higher than that in the control group (P<0.05). Fourteen days into treatment, PT, APTT and the blood flow velocity of the deep femoral vein were increased in the two groups compared with those before treatment (P<0.05); and PLT, Fib, D-D and the circumference of the limb (knee joint, 10 cm above the patella and 10 cm below the patella) were all reduced in the two groups (P<0.05). Compared with the control group 14 days into treatment, the blood flow velocity of the deep femoral vein was higher (P<0.05), PLT, Fib, D-D and the circumference of the limb (knee joint, 10 cm above the patella and 10 cm below the patella) were all lower in the observation group (P<0.05). The total effective rate was 97.1% (34/35) in the observation group, higher than 85.7% (30/35) in the control group (P<0.05). CONCLUSION Aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban can effectively treat lower extremity venous thrombosis after total knee arthroplasty, relieve hypercoagulation, accelerate the blood flow velocity and alleviate swelling of the lower extremity in the patients with knee osteoarthritis.

MAGED4B belongs to the melanoma-associated antigen family; originally found in melanoma, it is expressed in various types of cancer, and is especially enriched in glioblastoma. However, the functional role and molecular mechanisms of MAGED4B in glioma are still unclear. In this study, we found that the MAGED4B level was higher in glioma tissue than that in non-cancer tissue, and the level was positively correlated with glioma grade, tumor diameter, Ki-67 level, and patient age. The patients with higher levels had a worse prognosis than those with lower MAGED4B levels. In glioma cells, MAGED4B overexpression promoted proliferation, invasion, and migration, as well as decreasing apoptosis and the chemosensitivity to cisplatin and temozolomide. On the contrary, MAGED4B knockdown in glioma cells inhibited proliferation, invasion, and migration, as well as increasing apoptosis and the chemosensitivity to cisplatin and temozolomide. MAGED4B knockdown also inhibited the growth of gliomas implanted into the rat brain. The interaction between MAGED4B and tripartite motif-containing 27 (TRIM27) in glioma cells was detected by co-immunoprecipitation assay, which showed that MAGED4B was co-localized with TRIM27. In addition, MAGED4B overexpression down-regulated the TRIM27 protein level, and this was blocked by carbobenzoxyl-L-leucyl-L-leucyl-L-leucine (MG132), an inhibitor of the proteasome. On the contrary, MAGED4B knockdown up-regulated the TRIM27 level. Furthermore, MAGED4B overexpression increased TRIM27 ubiquitination in the presence of MG132. Accordingly, MAGED4B down-regulated the protein levels of genes downstream of ubiquitin-specific protease 7 (USP7) involved in the tumor necrosis factor-alpha (TNF-α)-induced apoptotic pathway. These findings indicate that MAGED4B promotes glioma growth via a TRIM27/USP7/receptor-interacting serine/threonine-protein kinase 1 (RIP1)-dependent TNF-α-induced apoptotic pathway, which suggests that MAGED4B is a potential target for glioma diagnosis and treatment.

Abstract OBJECTIVE To analyze the characteristics of drug poisoning in children, and to explore the diverse pharmaceutical services that pharmacists can provide in the process of prevention and treatment. METHODS The 47 children diagnosed as drug poisoning in Ningbo Women and Children's Hospital from January 1, 2020 to June 30, 2023 were retrospectively enrolled. Combined with the actual situation of Ningbo Women and Children's Hospital, pharmaceutical services were discussed. RESULTS The majority of children with drug poisoning were adolescent girls. The main cause of poisoning was intentional drug ingestion for suicide, accounting for 33 cases(70.21%). Additionally, 12 cases(25.53%) were accidental ingestion by children and 2 cases(4.26%) of drug overdose were caused by parents misreading the dosage of drugs. The clinical symptoms included drowsiness and/or lethargy(28 cases), dizziness(16 cases), nausea and/or vomiting(14 cases), and abdominal pain(11 cases). The majority of toxic substances were psychiatric drugs, accounting for 39 cases(82.98%). After hospitalization, 40 patients(85.11%) were treated with gastric lavage, and 11 patients(23.40%) were treated with blood purification. Diuresis and catharsis were also applied to remove poison. In addition, specific drug antidotes were selected according to the type of poisons. Meanwhile, symptomatic and supportive therapies were used. Finally, all 47 patients improved or cured after hospitalization. CONCLUSION Based on the characteristics of drug poisoning in children, pharmacists can actively participate in prevention and treatment, in order to reduce the occurrence of drug poisoning and improve the prognosis of poisoned children. In terms of prevention, pharmacists should provide medication instructions and education when dispensing drugs, especially for psychotropic drugs and drugs with easily confused dosage. In the treatment, clinical pharmacists can provide comprehensive pharmaceutical care for poisoned children from various aspects such as drug detection and analysis, removal of toxics, selection of specific antidotes, and inquiry of drug dosage for children.
