OBJECTIVE To summarize the current situation of pharmaceutical clinic service in our hospital over the past five years， and explore sustainable development strategies for service models of pharmaceutical clinics. METHODS A retrospective analysis was conducted on the consultation records of patients who registered and established files at the pharmaceutical clinic in our hospital from January 2019 to December 2023. Statistical analysis was performed on patients’ general information， medication- related problems， and types of pharmaceutical services provided by pharmacists. RESULTS A total of 963 consultation records were included， among which females aged 20-39 years accounted for the highest proportion （66.04%）； obstetrics and gynecology- related consultations accounted for the largest number of cases. Additionally， 80 patients attended follow-up visits at our hospital’s pharmaceutical clinic. A total of 1 029 medication-related issues were resolved， including 538 cases of drug consultations （52.28%）， 453 medication recommendations （44.02%）， 22 medication restructuring（2.14%）， and 16 medication education （1.55%）； the most common types of medication-related problems identified were adverse drug events（70.07%）. CONCLUSIONS Although the pharmaceutical clinic has achieved recognition from clinicians and patients， challenges such as low awareness among healthcare providers and the public persist. Future efforts should focus on strengthening information technology construction， enhancing pharmacist training， and establishing various forms of outpatient pharmaceutical service models.

The writing of pharmacist-managed clinics documents （hereinafter referred to as “outpatient medication record”） is a necessary part of pharmacist-managed clinics service. Outpatient medication record is an important carrier to reflect the quality of pharmacist-managed clinics service. The Chinese Hospital Association Pharmaceutical Specialized Committee was entrusted by the Pharmaceutical Administration Department of the National Health Commission to lead the formulation of the Guidelines for the Pharmacist-managed Clinics Service and Document Writing and Usage （Reference） （hereinafter referred to as Guidelines） according to the compilation method of group standards and the technical route of “documentation combing→framework establishment→draft writing→opinion collection→Guidelines formation”. The Guidelines standardizes the basic requirements of pharmacist-managed clinics record management and the basic content of record， and provides a general template and two specialized templates including pregnant and lactating pharmacist-managed clinics record template and cough and asthma pharmacist-managed clinics record template， which provides a reference for medical institutions to write pharmacist-managed clinics record. This paper introduces the formulation process of Guidelines and analyzes the key contents of Guidelines， which is helpful for the application practice of Guidelines and further improves the quality of pharmacist-managed clinics work.

Objective: To investigate prevalence of hepatitis E virus (HEV) infection among voluntary blood donors in Dalian and provide evidence for enhancing blood screening strategies. Methods: A total of 3 277 blood donor samples collected between December 2023 and February 2024 at Dalian Blood Center underwent routine blood screening (ALT, HBsAg, anti-HCV, HIV Ag/Ab, anti-TP, and HBV/HCV/HIV NAT). Subsequently, HEV antigen (Ag) was detected using chemiluminescence immunoassay (CLIA). HEV-Ag reactive samples were further tested for HEV RNA, IgM and IgG antibodies. Blood donors with repeated reactive HEV Ag results were followed up to clarify the status of infection. Results: Among the 3 277 blood donor samples, 6 (0.18%) were repeatedly reactive for HEV Ag. However, supplemental testing for HEV RNA, anti-HEV IgM, and anti-HEV IgG on these samples yielded non-reactive results. One of these six blood donors was successfully followed up. On day 218 after the initial detection of HEV Ag reactivity, HEV Ag, HEV RNA, HEV IgM and IgG antibody were found to be non-reactive. Conclusion: The reaction rate for HEV antigen screening among voluntary blood donors in Dalian is low. CLIA method for detecting HEV antigen is easy to operate and cost-effective, but demonstrates some false reactivity. Improving the specificity of the assay and combining it with nucleic acid testing (NAT) would be valuable for implementing a selective HEV screening strategy for blood donors.

BACKGROUND: Immunosuppression is closely related to the pathogenesis of sepsis, but the underlying mechanisms have not yet been fully elucidated. In this study, we aimed to examine the role of the Sterile Alpha Motif, Src Homology 3 domain and nuclear localization signal 1 (SAMSN1) in sepsis and elucidate its potential molecular mechanism in sepsis induced immunosuppression. METHODS: RNA sequencing databases were used to validate SAMSN1 expression in sepsis. The impact of SAMSN1 on sepsis was verified using gene knockout mice. Flow cytometry was employed to delineate how SAMSN1 affects immunity in sepsis, focusing on immune cell types and T cell functions. Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9)-mediated gene editing in RAW264.7 macrophages enabled interrogation of SAMSN1 's regulatory effects on essential macrophage functions, including cell proliferation and phagocytic capacity. The mechanism of SAMSN1 in the interaction between macrophages and T cells was investigated using the RAW264.7 cell line and primary cell lines. RESULTS: SAMSN1 expression was significantly increased in patients with sepsis and was positively correlated with sepsis mortality. Genetic deletion of Samsn1 in murine sepsis model improved T cell survival, elevated T cell cytolytic activity, and activated T cell signaling transduction. Concurrently, Samsn1 knockout augmented macrophage proliferation capacity and phagocytic efficiency. In macrophage, SAMSN1 binds to Kelch-like epichlorohydrin-associated protein 1 (KEAP1), causing nuclear factor erythroid 2-related factor 2 (NRF2) to dissociate from the KEAP1-NRF2 complex and translocate into the nucleus. This promotes the transcription of the coinhibitory molecules CD48/CD86/carcinoembryonic antigen related cell adhesion molecule 1 (CEACAM1), which bind to their corresponding receptors natural killer cell receptor 2B4/CD152/T cell immunoglobulin and mucin domain-containing protein 3 (TIM3) on the surface of T cells, inducing T-cell exhaustion. CONCLUSIONS SAMSN1 deletion augmented adaptive T cell immunity and macrophage phagocytic-proliferative dual function. Furthermore, it mediates the KEAP1-NRF2 axis, which affects the expression of coinhibitory molecules on macrophages, leading to T-cell exhaustion. This novel immunosuppression mechanism potentially provides a candidate molecular target for sepsis immunotherapy.

OBJECTIVE: To investigate the effectiveness of TiRobot-assisted minimally invasive treatment for fragility fractures of the pelvis (FFP) in elderly patients. METHODS: A retrospective analysis was conducted on the clinical data of 176 patients with FFP who were admitted between July 2018 and July 2024 and met the selection criteria. Among them, 95 patients underwent TiRobot-assisted closed reduction and minimally invasive cannulated screw fixation (robot group), while 81 patients underwent traditional open reduction and plate screw fixation (control group). There was no significant difference in baseline data such as gender, age, fracture classification, disease duration, and preoperative visual analogue scale (VAS) pain scores between the two groups ( P>0.05). The following parameters were recorded and compared between the two groups, including operation time, intraoperative blood loss, intraoperative transfusion rate, volume of intraoperative blood transfusion, maximum incision length, hospital stay, maximum residual displacement, reduction quality, fracture healing time, incidence of complications, VAS scores, Majeed pelvic function scores, and functional grading. RESULTS: All surgeries in both groups successfully completed. The robot group exhibited significantly shorter operation time, reduced intraoperative blood loss, lower intraoperative transfusion rate, smaller volume of intraoperative blood transfusion, shorter maximum incision length, and shorter hospital stay compared to the control group ( P<0.05). In the robot group, a total of 14 INFIX internal fixation frames and 280 cannulated screws were implanted, among which 250 screws were rated as excellent, 17 as good, and 13 as poor, resulting in a screw placement excellent and good rate of 95.36%. Radiological review revealed that the excellent and good rate of reduction quality was in 91.58% (87/95) in the robot group and 81.48% (66/81) in the control group, with no significant difference in postoperative maximum residual fracture displacement or reduction quality between the two groups (P>0.05). All patients in both groups were followed up 12-66 months, with an average of 28.9 months, and there was no significant difference in follow-up time between the two groups ( P>0.05). The fracture healing time in the robot group was significantly shorter than that in the control group ( P<0.05). At last follow-up, both groups showed significant improvement in VAS scores compared to preoperative values ( P<0.05); the change values of VAS scores, Majeed scores, and the excellent and good rate of Majeed pelvic function were significantly higher in the robot group than in the control group ( P<0.05). Regarding postoperative complications, there was no significant difference between the two groups in terms of gait changes, secondary surgeries, heterotopic ossification, incision infections, walking difficulties, internal fixation failure, or mortality rates ( P>0.05); however, the incidence of delayed wound healing was significantly lower in the robot group than in the control group ( P<0.05). CONCLUSION TiRobot-assisted minimally invasive treatment of elderly FFP is superior to traditional open reduction and internal fixation in terms of surgical trauma control, postoperative rehabilitation speed, and functional recovery.

BackgroundGenetic factor plays an important role in the pathogenesis of panic disorder. Previous studies have revealed that immune system dysregulation is closely related to mental disorders such as panic disorder， while the relationship between panic disorder and immune-related gene expression remains unclear. ObjectiveTo explore the relationship between the expression of CXCL8， IL6R， JUN， PTGS2， TGFBR1， TLR2， CCR4 genes and panic disorder， providing references for the diagnosis and treatment of panic disorder. MethodsA total of 52 patients who met the diagnostic criteria for panic disorder according to the Diagnosed and Statistical Manual of Mental Disorders， fourth edition （DSM-IV） were enrolled at the Psychosomatic Medicine Center of Sichuan Provincial People's Hospital from January 2020 to March 2021. Another 72 healthy individuals matched for age and gender from Chengdu were concurrently recruited as control group. The Panic Disorder Severity Scale （PDSS） was used to assess the severity of symptoms in panic disorder patients. Quantitative real-time polymerase chain reaction （PCR） was used to detect gene expression levels in two groups. Spearman correlation analysis was adopted to determine the correlation between PDSS score and immune-related gene expression in research group. ResultsThe expression of the JUN， PTGS2 and TGFBR1 genes were significant higher in panic disorder patients than those in control group （Z=-4.172， -2.086， -3.018， P<0.05 or 0.01）. After false discovery rate （FDR） correction for multiple testing， the differential expression of JUN and TGFBR1 genes remained statistically significant between two groups （P<0.05）. There was no significant difference in the expression of CCR4， CXCL8， IL6R and TLR2 genes between two groups （P>0.05）. Correlation analysis revealed that the expression of the JUN gene in panic disorder patients was positively correlated with PDSS score （r=0.360， P<0.01）， while the CCR4， CXCL8， IL6R， PTGS2， TGFBR1 and TLR2 genes showed no statistically significant correlation with the PDSS score （P>0.05）. ConclusionThe expression of the JUN and TGFBR1 genes may be associated with panic disorder， and the expression of the JUN gene correlated with the severity of panic disorder. ［Funded by Science and Technology Plan Project of Sichuan Provincial Department of Science and Technology （number， 2021YJ0440）］

Objective To summarize the clinical characteristics of children with drug-induced hypersensitivity syndrome(DIHS)complicated with herpesvirus reactivation,and to promote the early and accurate identification,diagnosis,and treatment of DIHS in children.Methods The medication history,clinical manifestations,treatment,and prognosis of 12 children confirmed DIHS complicated with herpesvirus reactivation in Guangzhou Women and Children's Medical Center between January 2018 and March 2023 were retrospectively analyzed.The changes in hematological parameters,inflammatory indexes,and hepatic and renal function within 5 d before the eruption,5 d,and 6-10 d after eruption were compared.Results Of the 12 patients,the male-to-female ratio was 5∶1,with a median age of 27(interquartile range 20.50-34.75)months.Two or more antibiotics were used at least two to six weeks before onset,with a combination of 3 or more antibiotics in 7 children,and a combined or sequential application of 2 antibiotics in 5 children.The antibiotics included cephalosporins(n=12),semisynthetic penicillins(n=5),vancomycin(n=4)and azithromycins(n=7).All 12 patients presented fever,rashes,and multiple organ involvement.The rashes were red maculopapules in the early stage and then gradually developed into massive fusion exceeding 50%of the whole body.Among them,seven children were accompanied by facial edema,and two had purplish-red facial rashes.11 children suffered from exfoliative dermatitis in the later stage.12 children presented obviously enlarged lymph nodes.Liver involvement was the most common(100%,simple increase of transaminase in four children,cholestasis in six children,and hepatic failure in two children),and lung involvement was found in nine children.Laboratory examination showed no significant increase in leukocytes or eosinophils within 5 d before the eruption,but low levels of atypical lymphocytes.After the eruption,leukocytes,eosinophils,and atypical lymphocytes increased progressively.Inflammatory indexes of hypersensitive C-reactive protein(CRP),procalcitonin(PCT)increased dramatically before and after the eruption.All the children received intravenous immunoglobulin(IVIG)and methylprednisolone,two children were given antiviral therapy,and nine children were treated with multiple plasma exchanges.After treatment,nine children were cured,one developed immune reconstitution syndrome,and two died of hepatic failure.Conclusions Antibiotics are common allergenic drugs for DIHS in children.Its clinical manifestations include fever and rashes,accompanied by multiple organ involvement,such as the liver and lung.When leukocytes,eosinophils,and atypical lymphocytes are progressively elevated after the eruption,DIHS should be highly suspected,herpesvirus activation should be monitored,medication history should be traced,and early active immunotherapy and antiviral therapy should be conducted if necessary.

Objective To obtain the range of anatomical parameters of healthy knee joints in Chinese males and validate a statistical shape model(SSM)based on the geometric shape of a healthy knee to provide references for the design of knee SSM-based prostheses.Methods Computed tomography(CT)images of knee joints from 112 healthy males were acquired to build three-dimensional(3D)knee joint models.Each model was the target model separately,and the remaining models were used as the training set for principal component analysis(PCA).The obtained knee SSM was fitted to the target model to predict the SSM.The exact anatomical measurement points were marked on the sample and SSM prediction models,and 17 linear and 3 angular parameters were derived.The values of the anatomical parameters were statistically tested using an independent samples t-test and Mann-Whitney U-test,and the validity of the SSM in terms of geometric shape was demonstrated if the resulting P-values were all greater than 0.05.Results Qualitative and quantitative comparative analyses of anatomical parameters showed that the mean deviation of linear parameters was less than 6 mm,and that of angular parameters was less than 2.5°.The results of statistical tests showed P＞0.05 for all anatomical parameters,proving that the knee SSM prediction model was not statistically different from the true healthy model in terms of geometric shape.Conclusions This study derived a reference range of anatomical parameters for a healthy knee and demonstrated that the knee SSM model was consistent with the real healthy model in terms of shape.The results provide a reference for the design of knee SSM-based prostheses.

Objective To explore the carrier rate of thalassemia in Laibin city,Guangxi Province,and provide a theoretical basis for the prevention and control of thalassemia.Methods From January 2020 to December 2021,88 152 patients were screened for thalassemia in the outpatient department of the Women's and Children's Hospital of 4 counties,1 city and 1 district in Laibin by blood cell detection and hemoglobin electrophoresis.The common and rare genes in initially screened positive individuals were detected by gap polymerase chain reaction(Gap-PCR)and reverse dot blot(RBD),and the results were conducted by statistical analysis.Results ① There were 22 553 positive cases in the preliminary screening and 8 327 positive cases received the diagnosis of thalassemia gene.A total of 4 944 thalassemia carriers of thalassemia genes were detected,deducing that the total thalassemia carrier rate in the population of childbearing age in this region was 15.19%,including 3 200 cases of α-thalassemia carriers(64.73%),1 424 cases of β-thalassemia carriers(28.80%),and 320 cases of were carriers α-thalassemia combined with β-thalassemia(6.47%).② There were 3 168 cases of common thalassemia(99.00%)and 32 cases of rare thalassemia(1.00%)among α-thalassemia gene carriers.A total of 13 mutant genes and 34 genotypes were detected,and genotype SEA/αα was the comes first.③ Among the β-thalassemia gene carriers,there were 1 411 cases of(99.09%)common thalassemia and 13 cases(0.91%)of rare thalassemia.A total of 19 mutant genes and 25 genotypes were detected,with CD41-42(-CTTT)being the most common.④ A total of 53 different genotypes were detected in the carriers of α-thalassemia combined with β-thalassemia,and the top genotype was--SEA/αα βCD41-42M/βN.⑤ The carrier rates of Yao and Han nationality were comparable,and the differences were not significant(χ2=0.300,P=0.584).The differences in carrying rates between Zhuang and Yao(χ2=23.66,P＜0.001),and between Zhuang and Han(χ2=116.98,P＜0.001)were significant.⑥ The carrier rate in Xiangzhou County was the highest(20.04%),while the carrier rate in Heshan City was the lowest(12.38%).⑦ The carrier rate of females was higher than that of males,and the difference was significant(χ2=182.03,P＜0.001).Conclusion The variants genotypes of thalassemia in Laibin were complex.This study was the first to investigate the carrier rate and gene mutation spectrum of thalassemia in Laibin Area,which provides valuable baseline data for genetic counseling and prenatal diagnosis.
