OBJECTIVE To explore optimization pathways for the drug traceability code management model in outpatient pharmacy workflows， providing practical evidence for enhancing the efficiency of pharmaceutical service. METHODS Taking the outpatient pharmacy of the First Affiliated Hospital of Sun Yat-sen University as the research subject， a comprehensive drug traceability system was established through three key interventions： upgrading the information system architecture [including integration of the hospital information system （HIS） with the traceability platform]， workflow optimization （reorganizing the inventory-dispensing-verification tripartite process）， and designing a dual-mode traceability data collection mechanism （primary data capture at dispensing stations and supplementary capture at verification stations）. Operational efficiency differences before and after implementation were analyzed using the medical insurance data and service timeliness metrics in September 2024. RESULTS After the implementation of drug traceability code management， in terms of data collection: Mode Ⅰ （verification-stage capture） uploaded 26 144 records， while Mode Ⅲ （inventory-as-sales capture） uploaded 443 061 records， totaling 469 205 entries； in terms of time efficiency： average drug dispensing time increased from 28.74 s to 43.37 s （enhanced by 51%）. Through dynamic staffing adjustments， patient wait time only extended from 8.04 min to 8.67 min （enhanced by 8%）. CONCLUSIONS Drug traceability code management can be effectively implemented via a “system reconstruction-process reengineering-human-machine collaboration” trinity strategy， leveraging informatization （e.g.， dual-mode data capture） to offset manual operation delays， which validates the feasibility of balancing national traceability demands with service efficiency in outpatient pharmacies.

BACKGROUND:Pelvic fractures encompass a range of types,and the utilization of a pelvic reduction frame for restoration often lacks a systematic repositioning method.Instead,it relies on the operator's experience in conjunction with fluoroscopic findings,which can lead to uncertainty and non-reproducibility. OBJECTIVE:To investigate the clinical efficacy of combining computer-simulated repositioning techniques with a pelvic reduction frame for the treatment of anteroposterior compression-III pelvic fractures. METHODS:A retrospective analysis was conducted on 19 patients with anteroposterior compression-III pelvic fractures who underwent preoperative repositioning via computer simulation and intraoperative repositioning with the assistance of a pelvic reduction frame between January 2018 and December 2021.Among them,7 cases were fixed with double plate in anterior ring and 12 cases were fixed with single plate combined with anterior subcutaneous internal fixation(INFIX).All patients received posterior ring fixation with two sacroiliac screws.Operative duration,intraoperative reduction time,the frequency of intraoperative fluoroscopy use,blood loss,and follow-up duration were documented.These data were utilized to monitor fracture healing time and postoperative complications.Fracture reduction quality was evaluated according to the Matta scale,and the Majeed Pelvic Function Score was employed to assess patient function during the final follow-up. RESULTS AND CONCLUSION:(1)Surgery was successfully completed in all 19 patients.The anterior ring was secured with double plates in 7 cases,while a single plate combined with INFIX was utilized in 12 cases.The posterior ring was stabilized with two sacroiliac screws,specifically targeting the S1 and S2 cones.(2)The operation duration ranged from 74 to 147 minutes,with a mean of(101.63±19.55)minutes.Intraoperative repositioning took place over a period of 26 to 41 minutes,with a mean of(38.11±3.31)minutes.The number of intraoperative fluoroscopies conducted ranged from 35 to 81,with a mean of(62.68±13.11)times.Intraoperative bleeding volumes varied from 60 to 130 mL,with a mean of(85.37±20.57)mL.(3)All the patients were diligently monitored for a duration of 12 to 26 months.Fracture healing was observed within a time frame of 12 to 20 weeks,with a mean of(16.37±2.50)weeks.(4)The evaluation according to Matta's criteria one day post-surgery revealed excellent outcomes in 14 cases and good outcomes in 5 cases.At the final follow-up,the Majeed function score indicated excellent results in 16 cases and good results in 3 cases.(5)Two patients experienced localized fat liquefaction phenomena,characterized by redness,swelling,and oozing at the incision site,which gradually resolved with proactive dressing changes.None of the patients encountered complications such as internal fixation loosening,loss of fracture reduction,or nerve injuries post-surgery.It is concluded that the combined approach of using computer-simulated repositioning techniques in conjunction with pelvic reduction frames for the treatment of anteroposterior compression-III pelvic fractures has advantages in enhancing repositioning efficiency and improving pelvic function.

ObjectiveTo establish a geographical origin identification model for Foeniculi Fructus from Haiyuan， providing a new technical reference for the protection of Haiyuan's geo-authentic medicinal materials and its designation as a national geographical indication agricultural product. MethodsSamples of Foeniculi Fructus were collected from eight producing areas， including Minqin （Gansu）， Bozhou （Anhui）， Qingdao （Shandong）， Dezhou （Shandong）， Urumqi （Xinjiang）， Nujiang （Yunnan）， Gutuo （Inner Mongolia）， and Haiyuan （Ningxia）. Gas chromatography-ion mobility spectrometry （GC-IMS） was used to detect the volatile organic compounds （VOCs） in samples from these geographic origins. VOCs were qualitatively analyzed through dual matching with the National Institute of Standards and Technology （NIST） mass spectral database and the IMS drift time database. Using the Reporter module and Gallery Plot visualization tools within the LAV analytical platform， VOC fingerprint profiles characterizing geographic origins were constructed. A non-targeted analytical strategy was adopted， and 97 VOCs detected via GC-IMS were subjected to principal component analysis （PCA） and partial least squares discriminant analysis （PLS-DA） based on their differential distribution patterns to construct an origin identification model for Foeniculi Fructus from Haiyuan region. Key discriminative markers were screened using variable importance in projection （VIP） values greater than 1. ResultsA total of 97 VOCs were identified， including alcohols， aldehydes， ketones， esters， organic acids， terpenoids， ethers， alkenes， and benzenes. The PLS-DA model， based on VOCs data obtained by GC-IMS， effectively distinguished Foeniculi Fructus in Haiyuan region from those of other origins. During cross-validation， the model achieved a prediction parameter （Q²） of 0.976 and a goodness-of-fit parameter （R²） of 0.936， with no overfitting observed in permutation testing. Twelve key flavor markers with VIP > 1 were identified as characteristic indicators of Haiyuan origin. ConclusionA stable and highly predictive origin identification model for Foeniculi Fructus from Haiyuan was successfully established using GC-IMS technology， PLS-DA， and VIP-based marker screening. This model provides a novel technical strategy for accurately distinguishing Foeniculi Fructus in Haiyuan region from other regional varieties and offers new technical support for its protection as a geo-authentic medicinal material and a nationally designated geographical indication agricultural product in China.

Objective:To explore the influencing factors of intracranial hemorrhage in elderly patients with acute occlusion of intracranial arteries after treatment and reperfusion.Methods:A retrospective selection was conducted on elderly patients with acute occlusion of the intracranial artery who were treated at the Hebei Petro China Central Hospital from February 2019 to May 2021. Sixty patients who received mechanical thrombectomy treatment were selected as the observation group, and 60 patients who received combined arterial and venous thrombolysis treatment were selected as the control group. The vascular reperfusion rate and incidence of intracranial hemorrhage were observed and compared between the two groups. Meanwhile, multiple logistic regression analysis was used to identify the influencing factors of intracranial hemorrhage.Results:The reperfusion rate of the observation group′s blood vessels was 85.00%(51/60), significantly higher than the control group′s 68.33%(41/60), and the difference was statistically significant (χ 2=4.658, P=0.031). The National Institutes of Health Neurological Deficit Score (NIHSS) of the observation group after treatment was (10.57±2.23), significantly lower than that of the control group (14.73±2.84), and the difference was statistically significant ( P<0.05). The reperfusion rate of blood vessels in patients under 80 years old in the observation group was significantly higher than that in patients ≥80 years old ( P<0.05). The results of univariate analysis showed that there were statistically significant differences in age, NIHSS at admission, Alberta Stroke Program Early CT Score (ASPECTS), and neutrophil absolute value/lymphocyte ratio (NLR) between patients with and without intracranial hemorrhage (all P<0.05); Multivariate logistic regression analysis showed that age ( OR=1.756, 95% CI: 1.184-2.604) and NIHSS at admission ( OR=2.392, 95% CI: 1.401-4.084) were risk factors for postoperative intracranial hemorrhage in elderly patients with acute occlusion of the large intracranial artery, while ASPECTS ( OR=0.364, 95% CI: 0.190-0.697) was a protective factor. Conclusions:Mechanical thrombectomy has good clinical efficacy in the treatment of elderly patients with acute occlusion of intracranial arteries, and is worthy of clinical use; The intracranial hemorrhage after reperfusion is mainly influenced by the patient′s age, NIHSS at admission, and ASPECTS.

ObjectiveTo observe the protective effect of Didang Xianxiong decoction on the kidneys of diabetic rats， its regulation on the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway， and its influence on podocyte apoptosis and explore the mechanism of Didang Xianxiong decoction in improving diabetic nephropathy. MethodThe diabetic model was established by a single intraperitoneal injection of streptozotocin （STZ） solution of 55 mg·kg^-1. The successfully replicated model rats were randomly divided into the model group， Didang Xianxiong decoction group （8.10 g·kg^-1）， Xiao Xianxiongtang group （4.05 g·kg^-1）， Didangtang group （4.05 g·kg^-1）， and alagebrium （ALT-711） group （3 mg·kg^-1）， with six rats in each group. In addition， six rats were included in the blank group. After continuous administration for eight weeks， hematoxylin-eosin （HE） staining was used to observe the pathological changes in rats' kidney tissue. Masson staining was used to observe the degree of collagen deposition. Periodic acid-Schiff （PAS） staining was used to observe basement membrane lesions， and immunohistochemistry was used to detect the expression of phosphorylation （p）-PI3K and p-Akt proteins in rats' kidney tissue. The terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling （TUNEL） method was used to detect podocyte apoptosis. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of PI3K and Akt in rats' kidney tissue. Western blot was used to detect the protein expression of PI3K， p-PI3K， Akt， p-Akt， B-cell lymphoma 2 （Bcl-2）， Bcl-2-associated X protein （Bax）， phosphorylation glycogen synthase kinase-3β （p-GSK-3β）， and Caspase-3 in the kidney tissue. ResultCompared with the normal group， the model group had compensatory expansion of glomeruli， proliferation of mesangial cells， a large amount of collagen deposition in the mesangial stroma， thickening of the basement membrane， decreased mRNA expression of PI3K and Akt， and inhibition of PI3K and Akt protein phosphorylation （P<0.01）. It also underwent enhanced apoptotic signaling， decreased expression of anti-apoptotic protein Bcl-2 （P<0.01）， and increased expression of Bax， p-GSK-3β， and Caspase-3 （P<0.01）. Compared with the model group， Didang Xianxiong decoction significantly improved kidney tissue pathology， increased mRNA expression of PI3K and Akt （P<0.01）， significantly up-regulated phosphorylation levels of PI3K and Akt proteins （P<0.01） and Bcl-2 expression （P<0.01）， downregulated the expression of Bax， p-GSK-3β， and Caspase-3 （P<0.01）， and weakened podocyte apoptotic signaling. ConclusionDidang Xianxiong decoction may promote the activation of the PI3K/Akt signaling pathway， inhibit podocyte apoptosis， and thus slow down the progression of diabetic nephropathy.

Objective:To construct a novel dual-specific antibody targeting human CD123 (CD123 DuAb) and study its effects in acute myeloid leukemia (AML) .Methods:Based on the variable region of the CD123 monoclonal antibody independently developed at our institution, the CD123 DuAb expression plasmid was constructed by molecular cloning and transfected into ExpiCHO-S cells to prepare the antibody protein. Through a series of in vitro experiments, its activation and proliferation effect on T cells, as well as the effect of promoting T-cell killing of AML cells, were verified.Results:① A novel CD123 DuAb plasmid targeting CD123 was successfully constructed and expressed in the Expi-CHO eukaryotic system. ②The CD123 DuAb could bind both CD3 on T cells and CD123 on CD123 + tumor cells. ③When T cells were co-cultured with MV4-11 cells with addition of the CD123 DuAb at a concentration of 1 nmol/L, the positive expression rates of CD69 and CD25 on T cells were 68.0% and 44.3%, respectively, which were significantly higher than those of the control group ( P<0.05). ④Co-culture with CD123 DuAb at 1 nmol/L promoted T-cell proliferation, and the absolute T-cell count increased from 5×10 5/ml to 3.2×10 6/ml on day 9, and CFSE fluorescence intensity decreased significantly. ⑤ With the increase in CD123 DuAb concentration in the culture system, T-cell exhaustion and apoptosis increased. When the CD123 DuAb was added at a concentration of 1 nmol/L to the culture system, the proportion of CD8 + PD-1 + LAG-3 + T cells was 10.90%, and the proportion of propidium iodide (PI) - Annexin Ⅴ + T cells and PI + Annexin Ⅴ + T cells was 18.27% and 11.43%, respectively, which were significantly higher than those in the control group ( P<0.05). ⑥ The CD123 DuAb significantly activated T cells, and the activation intensity was positively correlated with its concentration. The expression rate of CD107a on T cells reached 16.05% with 1 nmol/L CD123 DuAb, which was significantly higher than that of the control group ( P<0.05). ⑦The CD123 DuAb promoted cytokine secretion by T cells at a concentration of 1 nmol/L, and the concentration of IFN-γ and TNF-α in the supernatant of the co-culture system reached 193.8 pg/ml and 169.8 pg/ml, respectively, which was significantly higher than that of the control group ( P<0.05). ⑧When CD123 DuAb was added at a concentration of 1 nmol/L to the co-culture system of T cells and CD123 + tumor cells, the killing intensity of T cells significantly increased, and the residual rates of CD123 + MV4-11 cells, CD123 + Molm13 cells, and CD123 + THP-1 cells were 7.4%, 6.7%, and 14.6% on day 3, respectively, which were significantly lower than those in the control group ( P<0.05) . Conclusion:In this study, a novel CD123 DuAb was constructed and expressed. In vitro experiments verified that the DuAb binds to CD123 + tumor cells and T cells simultaneously, promotes T-cell activation and proliferation, and facilitates their anti-leukemia effect, which provides a basis for further clinical research.

Objective:To construct a novel chimeric antigen receptor T (CAR-T) cell targeting CD138 and to investigate its cytotoxicity against myeloma cells.Methods:The hybridoma strain that can stably secrete the CD138 monoclonal antibody (mAb) was prepared and obtained through monoclonal antibody screening technology. The hybridoma strain cells were intraperitoneally injected into mice to produce ascites containing monoclonal antibodies, which were then collected and purified to obtain pure CD138 mAb. Further examinations were performed to assess the biological characteristics of CD138 mAb. The variable region sequence of this antibody was amplified through reverse transcription polymerase chain reaction and was used as the antigen recognition domain of CD138 CAR, which was subsequently expressed on the surface of T cells by lentiviral infection. Flow cytometry was employed to assess the phenotype of CD138 CAR-T cells. In vitro cytotoxicity and degranulation assays were performed to evaluate their antitumor effects.Results:① We successfully prepared anti-human CD138 antibody hybridoma cell lines and screened a hybridoma cell strain, 5G2, which could persistently and stably secrete the anti-CD138 antibody. ② The purified CD138 (5G2) mAb can especially recognize CD138 + cells with a binding affinity constant (K D) of 6.011×10 -9 mol/L and showed no significant binding activity with CD138 - cells. ③The variable region sequence of the CD138 (5G2) antibody was obtained using molecular cloning technology, and CD138 (5G2) CAR was successfully constructed and expressed on T cells through lentivirus infection and, concurrently, demonstrated effective binding to recombinant human CD138 protein.④ The proliferation of T cells transduced with the CD138 (5G2) CAR was highly efficient. The phenotype analysis revealed that CD138 (5G2) CAR-T cells exhibited a greater tendency to differentiate into central memory T cells and memory stem T cells, with a reduced proportion of terminally differentiated effector memory subsets. ⑤CD138 (5G2) CAR-T cells demonstrated specific cytotoxicity against CD138 + myeloma cell line H929, whereas CD138 - cell line K562 remained unaffected. The percentage of residual H929 cells was (12.92±8.02) % after co-culturing with CD138 (5G2) CAR-T cells, while (54.25±15.79) % was left in the Vector-T group (E∶T=1∶2; P<0.001). ⑥Results of degranulation assays demonstrated a significant activation of CD138 (5G2) CAR-T cells after co-culture with the H929 cell line, whereas no significant activation was observed in Vector-T cells [ (25.78±3.35) % vs (6.13±1.30) %, P<0.001]. ⑦After co-culturing with CD138 + cells, CD138 (5G2) CAR-T cells exhibited a significant increase in cytokine secretion compared to the Vector-T group [interleukin-2: (1 697.52±599.05) pg/ml vs (5.07±1.17) pg/ml, P<0.001; interferon-γ: (3 312.20±486.38) pg/ml vs (9.28±1.46) pg/ml, P<0.001; and tumor necrosis factor-α: (1 837.43±640.49) pg/ml vs (8.75±1.65) pg/ml, P<0.001]. However, no significant difference was observed in cytokine secretion levels between the two groups after co-culturing with CD138 - cells. Conclusion:This study successfully prepared a novel monoclonal antibody against CD138, and CAR-T cells constructed with the antigen recognition domain derived from this 5G2 mAb demonstrated effective antitumor activity against myeloma cells. This can be used as a new option for the detection of the CD138 antigen and proposes a novel strategy for multiple myeloma immunotherapy.

Epilepsy patients are prone to obesity and metabolic syndrome(MetS),which is a higher risk than the general population.Nonalcoholic fatty liver disease(NAFLD)is a manifestation of a metabolic syndrome,characterized by hepatic steatosis,which can be exacerbated to some extent in patients with epilepsy.Sodium valproate(VPA),a commonly used clinical antiepileptic drug,leads to triglyceride accumulation in liver cells and induces a risk of NAFLD.In adults with epilepsy combined with NAFLD,treatment with VPA can make the liver,which is already affected by steatosis,more sensitive to VPA-induced liver injury and affect VPA drug metabolism.Both VPA and NAFLD induce hepatic steatosis,and can exacerbate each other's induced hepatic steatosis synergistically during epilepsy treatment.In this paper,we reviewed the progress of clinical studies on the use of VPA in adult patients with epilepsy combined with NAFLD to provide references for effective treatment and future studies of VPA.
