OBJECTIVE: To analyze the pathogens distribution in patients with ventilator-associated pneumonia (VAP), and their association with anti-β-glucan receptor-1 (Dectin-1)/spleen tyrosine kinase (Syk) signaling pathway, and to provide scientific basis for formulating more effective treatment strategies and preventive measures. METHODS: A prospective study was conducted. 160 patients with VAP admitted to the department of critical care medicine of Xingtai People's Hospital from January 2021 to March 2023 were enrolled. The respiratory secretions of patients were collected for Candida colonization analysis, and then the bacteria in the respiratory secretions were identified by automatic microbial identification instrument. The expression levels of Dectin-1 and Syk in peripheral blood mononuclear cells were detected by fluorescent immunopolymerase chain reaction. Clinical pulmonary infection score (CPIS) was performed based on imaging, clinical and microbiological criteria. The basic data, pathogen distribution, Dectin-1 and Syk expression levels and CPIS score of the two groups were compared. Spearman test was used to analyze the correlation between the expression levels of Dectin-1 and Syk and respiratory Candida colonization and CPIS score. RESULTS: 160 VAP patients, 97 were Candida colonized (colonized group) and 63 were not (non-colonized group). There were significantly differences in gender (males: 57.73% vs. 41.27%, P = 0.042) and age (years: 57.98±12.46 vs. 62.09±10.61, P = 0.029) between the colonized group and the non-colonized group, while there were no significantly differences in the data of duration of mechanical ventilation, underlying diseases and primary diseases. The distribution of pathogenic bacteria showed that the infection rate of Staphylococcus aureus in the colonized group was significantly higher than that in the non-colonized group (24.74% vs. 7.94%, P < 0.05), and there was no significantly difference in the infection rate of other G-positive and G-negative bacteria between the two groups. The CPIS score in the colonized group was significantly higher than that in the non-colonized group (8.73±0.43 vs. 7.31±0.39, P < 0.01), and the expression levels of Dectin-1 and Syk in peripheral blood mononuclear cells were significantly higher than those in the non-colonized group (Dectin-1/U6: 0.86±0.22 vs. 0.47±0.16, Syk/U6: 0.77±0.18 vs. 0.42±0.11, both P < 0.01). The expression levels of Dectin-1 and Syk in peripheral blood mononuclear cells of VAP patients were significantly positively correlated with the colonization of respiratory Candida (r values were 0.754 and 0.631, respectively, both P < 0.05), and were significantly positively correlated with CPIS score (r values were 0.594 and 0.618, respectively, both P < 0.05). CONCLUSION The proportion of Staphylococcus aureus in VAP patients with respiratory Candida colonization is higher, and Dectin-1/Syk signaling pathway is significantly positively correlated with respiratory Candida colonization and CPIS score.

The feasibility and barriers to pharmacists providing these services were examined. Results The involvement of pharmacists in smoking cessation positively impacted public health and the economy. Endowing pharmacists with the authority to prescribe smoking cessation medications, providing training in this service, and bolstering their potential through interprofessional collaboration can effectively address the barriers to their role in smoking cessation. Conclusion It is advisable to consider integrating smoking cessation services led by pharmacist into healthcare and public health policy guidelines ,which could enhance the efficacy and sustainability of smoking cessation initiatives.

Caveolin-1(CAV1)is a structural protein of caveolae on the plasma membrane and is an important regulatory factor for liver function.CAV1 regulates hepatic lipid deposition,lipid and glucose metabolism,mitochondrial function,and hepatocyte proliferation through various molecular pathways.Therefore,CAV1 plays a crucial role in maintaining liver physiology during the metabolic regulatory processes such as hepatic steatosis and hepatocyte proliferation.Furthermore,CAV1 is also involved in the development and progression of different types of liver injury,hepatitis,and liver cirrhosis.This article reviews the role of CAV1 in liver-related diseases and its mechanism in the regulation of liver macrophages,so as to provide a theoretical basis for targeting CAV1 in the treatment of liver-related diseases.

Objective To rationally allocate pharmaceutical and healthcare human resources,and to explore the feasibility of implementing the system of licensed assistant pharmacists in retail pharmacies.Methods Through literature review,questionnaire surveys,and statistical analysis of exam scores,the training status of pharmacy technicians with secondary vocational education,the employment situation in retail pharmacies,and the results of the licensed pharmacist qualification examination were deeply understood.Results Every year,a certain number of graduates with a secondary vocational education in pharmacy entered society,and retail pharmacies were willing to recruit pharmacy technicians with this educational background,their professional competence were recognized.Pharmacy technicians with secondary vocational education can obtain the professional qualification of practicing pharmacists through hard work,and demonstrated the basic competency for working as licensed assistant pharmacists.Conclusion The implementation of the licensed assistant pharmacist system among pharmacy technicians with secondary vocational education in retail pharmacies is feasible.This system can fully leverage the role of pharmacy technicians with secondary vocational education,make up for the shortage of professional personnel in certain regions,promote the construction of the pharmaceutical care system in retail pharmacies,and ensure drug quality and medication safety.

Objective:To investigate the clinical therapeutic effect of ultrasound-guided paravertebral nerve block combined with platelet rich plasma (PRP) injection on patients with postherpetic neuralgia (PHN).Methods:Sixty PHN patients diagnosed at the First Affiliated Hospital of Bengbu Medical University from August 2023 to June 2024 were selected and randomly divided into a control group and an observation group using a random number table. The control group received ultrasound-guided paravertebral nerve block, while the observation group received PRP injection in addition to the control group. The two groups were compared before treatment (T 0), 1 week after treatment (T 1), 2 weeks after treatment (T 2), 3 weeks after treatment (T 3), 4 weeks after treatment (T 4), and 8 weeks after treatment (T 5), pain Visual Analogue Scale (VAS), Pittsburgh Sleep Quality Index (PSQI), Dermatology Quality of Life Index (DLQI) scores, and incidence of adverse reactions at each time point. Results:The pain VAS, PSQI, and DLQI scores of both groups of patients at T 1, T 2, T 3, T 4, and T 5 time points were reduced compared to T 0, and the pain VAS, PSQI, and DLQI scores of the observation group at T 1 to T 5 time points were lower than those of the control group (all P<0.05). The incidence of adverse reactions in the control group was 26.6%(8/30), while in the observation group it was 6.6%(2/30), with a statistically significant difference between the two groups (χ 2=4.320, P<0.05). The total effective rate of the control group [70.0%(21/30)] was lower than that of the observation group [93.3%(28/30)], with a statistically significant difference between the two groups (χ 2=5.454, P<0.05). Conclusions:The combined application of ultrasound-guided paravertebral nerve block and PRP injection for the treatment of PHN can significantly alleviate patients′ pain symptoms, improve their sleep and quality of life, with relatively few side effects and high safety.

OBJECTIVE To predict the development trends of licensed pharmacist staffing in retail pharmacies within the western China and provide reference for the formulation of policies related to licensed pharmacists. METHODS Based on the data of retail pharmacies and licensed pharmacists in the western China from 2016 to 2022， a grey model was constructed to analyze and predict the number development trends of retail pharmacies and licensed pharmacists in the western China from 2023 to 2026. RESULTS Currently， the 1∶1 staffing requirement for licensed pharmacists and retail pharmacies had been met in Shaanxi， Guangxi and Gansu. Based on current trends， Inner Mongolia， Chongqing， Yunnan， and Qinghai were expected to meet the 1∶1 staffing requirement for licensed pharmacists and retail pharmacies between 2023 and 2026. Sichuan and Xinjiang were also expected to meet this requirement in the future. However， there was still a significant gap in Guizhou， Xizang， and Ningxia towards achieving the above goals. CONCLUSIONS There is still a discrepancy between the deployment of licensed pharmacists and the national requirements in certain western provinces. Local authorities should formulate relevant policies according to local circumstances. Regions that have already met or will soon achieve the staffing requirement for licensed pharmacists should continue to enhance the quantity and quality of their licensed pharmacist workforce. In areas where meet this criterion in the short term is not feasible， it is necessary to strengthen the development of the licensed pharmacist workforce， and control the number of new retail pharmacies.

This paper summarized the implementation of the pharmacist examination outline of the seventh edition of the national professional qualification examination for licensed pharmacists, and pointed out the existing problems and deficiencies: unclear definition between disciplines, insufficient organic integration of knowledge, lack of practicability in the content selection of professional basic disciplines and so on. At the same time, corresponding revision suggestions are put forward for the revision ideas and contents of the syllabus of pharmaceutical examination: increase the degree of professional integration between disciplines and the breadth of relevant professional knowledge, start with clinical medication, emphasize people-centered pharmacy services, and pay attention to comprehensiveness and practicability. It is hoped to provide references for further improving the outline of the national licensed pharmacist qualification examination.

Objective:To evaluate the efficacy and safety of modified FC/ATG pretreatment in the treatment of severe aplastic anemia(SAA).Methods:From June 2012 to June 2020, clinical data of 64 patients with severe aplastic anemia undergoing allogeneic hematopoietic stem cell transplantation with modified FC/ATG(Flu 30 mg·m -2·d -l, -5~-2 d、CTX 50 mg·kg -1·d -1~-2 d、ATG: 2.5 mg·kg -1·d -1, -5~-2 d) pretreatment were retrospectively analyzed.There were MSD-HSCT ( n=29) and Haplo-HSCT ( n=35). Results:One patient died of intracerebral hemorrhage before transplantation and the remainders were completely implanted.During a median follow-up period of 14.5(1-95) months, overall survival (OS) rate of 92.2%.It was significantly higher than OS rate of 67.2% in the treatment of SAA by foreign pretreatment regimens containing low-dose TBI.And pretreatment scheme containing FC+ BU/TBI had an OS of slightly >91.3% in the treatment of SAA.The 3-year OS rates were 85.7% and 93.5% in Haplo-HSCT and MSD-HSCT groups ( P=0.058). The OS rate of SAA Haplo-HSCT/MSD-HSCT group was similar to that of " Beijing Protocol" (BU/CY+ ATG) (89%, 91%). The viral infection rates of EB and CMV were significantly higher in haplo-HSCT group than those in MSD-HSCT group and inter-group difference was statistically significant ( P<0.05). However, univariate analysis showed that two groups had no effect on survival time ( P=0.403, P=0.132). Univariate analysis showed that survival time was significantly associated with the presence of Ⅲ-Ⅳ° aGVHD and the presence of severe complications ( P=0.007, P=0.001). Further multivariate analysis revealed that severe complication was an independent risk factor for survival ( P=0.003). Conclusions:The efficacy of improved FC/ATG pretreatment in the treatment of SAA in MSD-HSCT or Haplo-HSCT is higher than other domestic and international pretreatment schemes in OS rate, safety and effectiveness.Onset of severe complication and association with Ⅲ ~ Ⅳ ° aGVHD are the influencing factors for patient survival.The efficacy of Haplo-HSCT group is similar to that of MSD-HSCT group.It may be employed as an alternative donor for SAA patients without fully congruent donors.

Objective:To analyze any changes in the functional connectivity between the seed points of the dorsolateral prefrontal cortex (DLPFC) and the whole brain, as well as any fluctuations in the low-frequency amplitude among persons with post-stroke depression (PSD). The aim was to develop correlations among functional imaging results, clinical scales, and inflammation indicators including high-sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6), interleukin 2 (IL-2), interleukin 10 (IL-10), interleukin 17a (IL-17a) and interferon-γ (IFN-γ).Methods:Between 2016 and 2020, 55 ischemic stroke survivors were tested. The 28 scoring 7 or more on the Hamilton Depression Scale (HAMD-17) formed the PSD group, while the 27 others formed the control group. Functional magnetic resonance images were collected, and serum inflammation indicators were determined.Results:When seed points in the left DLPFC were used, in the PSD group the frontal cortex (FC) decreased in one cluster, with a voxel of 129mm3 and the MNI coordinates (x=9, y=30, z=33) indicating that the anatomical automatic labeling (AAL) brain regions were the Cingulum_Ant_L, Cingulum_Mid_R and the frontal_Sup_Medial_L. When the right DLPFC was used as the seed point the FC again decreased in one cluster, with voxels of 44mm 3 and the MNI coordinates (x=-27, y=12, z=47) referring to the AAL brain region of the frontal_Mid_L. In the PSD group, the FC value of abnormal brain areas with the R-DLPFC as the seed point was positively correlated with time since stroke. In the control group, the FC value of abnormal brain areas with L-DLPFC as the seed point was negatively correlated with MoCA, while with R-DLPFC as the seed point it was positively correlated with IFN-γ. The FC values of abnormal areas of the brain showed no significant correlation with other clinical scales, inflammation indicators or lesion volume. Conclusion:Abnormal functional connections within the executive control network and between the salience networks may participate in the mechanism of PSD, and may be related to the time since stroke, cognitive functioning, and IFN-γ levels.

OBJECTIVES: To explore the application of random forest algorithm in screening the risk factors and predictive values for postpartum depression. METHODS: We recruited the participants from a tertiary hospital between June 2017 and June 2018 in Changsha City, and followed up from pregnancy up to 4-6 weeks postpartum.Demographic economics, psychosocial, biological, obstetric, and other factors were assessed at first trimesters with self-designed obstetric information questionnaire and the Chinese version of Edinburgh Postnatal Depression Scale (EPDS). During 4-6 weeks after delivery, the Chinese version of EPDS was used to score depression and self-designed questionnaire to collect data of delivery and postpartum. The data of subjects were randomly divided into the training data set and the verification data set according to the ratio of 3꞉1. The training data set was used to establish the random forest model of postpartum depression, and the verification data set was used to verify the predictive effects via the accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and AUC index. RESULTS: A total of 406 participants were in final analysis. Among them, 150 of whom had EPDS score ≥9, and the incidence of postpartum depression was 36.9%. The predictive effects of random forest model in the verification data set were at accuracy of 80.10%, sensitivity of 61.40%, specificity of 89.10%, positive predictive value of 73.00%, negative predictive value of 82.80%, and AUC index of 0.833. The top 10 predictive influential factors that screening by the variable importance measure in random forest model was antenatal depression, economic worries after delivery, work worries after delivery, free triiodothyronine in first trimesters, high-density lipoprotein in third trimester, venting temper to infants, total serum cholesterol and serum triglyceride in first trimester, hematocrit and serum triglyceride in third trimester. CONCLUSIONS Random forest has a great advantage in risk prediction for postpartum depression. Through comprehensive evaluation mechanism, it can identify the important influential factors for postpartum depression from complex multi-factors and conduct quantitative analysis, which is of great significance to identify the key factors for postpartum depression and carry out timely and effective intervention.
