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.

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.

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 evaluate the diagnostic efficacy of FibroScan combined with various noninvasive diagnostic models for liver fibrosis in patients with chronic hepatitis B (CHB) complicated with nonalcoholic fatty liver disease (NAFLD), and to establish a new predictive model with common clinical indicators.Methods:From January 2016 to May 2024, the clinical data of 118 CHB patients complicated with NAFLD from the First Affiliated Hospital of Zhengzhou University, who underwent liver biopsy and FibroScan examination were respectively analyzed. According to the Scheuer scoring system, different diagnostic endpoints were set based on the degree of liver fibrosis (S0 to S1, ≥S2, ≥S3, and S4), fibrosis stage ≥S2 was designated as the criterion for significant liver fibrosis. Fibrosis-4 (FIB-4), γ-glutamyl transpeptidase (GGT) to platelet ratio (GPR), GGT-age-platelet-international normalized ratio (GAPI) model, S index, King index and Forns index were calculated according to the common clinical indicators. The independent t test or Mann-Whitney U test was used to compare the two groups. Spearman rank correlation was used to analyze the correlation between each noninvasive diagnostic method and the degree of liver fibrosis. Receiver operating characteristic curve (ROC) was plotted, and the DeLong test was performed to compare the area under the curve (AUC), and to evaluate the predictive value of FibroScan combined with various noninvasive diagnostic models for the diagnosis of liver fibrosis. The laboratory indicators were compared between patients with non-significant liver fibrosis and patients with significant liver fibrosis. And the indicators with statistically significant differences ( P<0.05) in the univariate analysis were further analyzed by multivariate logistic regression to establish a new predictive model for liver fibrosis. Hosmer-Lemeshow test was used to assess the model′s goodness of fit. Results:The results of Spearman rank correlation showed that FIB-4, GPR, FibroScan, GAPI model, S index, King index, and Forns index were positively correlated with the stage of liver fibrosis ( r=0.413, 0.458, 0.512, 0.473, 0.533, 0.380 and 0.478, all P<0.001). The results of ROC analysis indicated that among combination of FibroScan and other diagnostic models, the AUC values of FibroScan+ FIB-4, FibroScan+ Forns index were relatively high in ≥S2 and ≥S3, which were 0.804 and 0.907, respectively. The platelet count ((200.65±50.89)×10 9/L vs. (169.96±63.68)×10 9/L), total cholesterol ((4.69±0.77) mmol/L vs. (4.32±1.00) mmol/L), high-density lipoprotein (HDL) (1.28 (1.05, 1.46) mmol/L vs. 1.08 (0.92, 1.21) mmol/L), total protein (74.00 (70.63, 77.08) g/L vs. 68.80 (64.60, 73.55) g/L), albumin (47.06 (44.65, 48.81) g/L vs. 44.70 (41.55, 46.20) g/L), and globulin (26.80 (24.48, 29.70) g/L vs. 25.80 (23.05, 27.60) g/L) of the non-significant liver fibrosis group were higher than those of the significant liver fibrosis group, and the differences were statistically significant ( t=2.74, 2.09; Z=-3.30, -3.88, -3.95, -2.01; P=0.007, =0.040, =0.001, <0.001, <0.001, =0.044). GGT (27.50 (17.00, 41.75) U/L vs. 37.00 (22.50, 87.00) U/L), the liver stiffness measurement (LSM) in the non-significant hepatic fibrosis group was lower than the significant liver fibrosis group (6.85 (5.60, 9.26) kPa vs. 11.60 (7.08, 17.26) kPa), and the differences were statistically significant ( Z=-2.73, -4.39; P=0.006, <0.001). The result of multivariate logistic regression analysis revealed that globulin, albumin, HDL, and LSM were independent factors of liver fibrosis ( OR (95% confidence interval)=0.865 (0.759 to 0.985), 0.804 (0.691 to 0.935), 0.128 (0.023 to 0.711), and 1.251 (1.091 to 1.433), respectively; P=0.029, 0.025, 0.019, 0.001). A novel model, GLAH, was established with globulin, LSM, albumin, and HDL. The AUC for diagnosing liver fibrosis degree ≥S2, ≥S3, and S4 was 0.847, 0.938, and 0.909, respectively, which were higher than those of the above models. The positive predictive value for diagnosing liver fibrosis degree ≥S2 with GLAH>1.12 as the cutoff value was 95.8%. The negative predictive value for excluding fibrosis stage ≥S2 with GLAH<-1.41 was 92.3%. This approach could reduce the number of liver biopsies by 48.3% (57/118), with an accuracy of 94.7% (54/57). Conclusions:The clinical value of FibroScan combined with FIB-4 or Forns index is better in the diagnisis of fibrosis stage ≥S2 and ≥S3. The GLAH model has higher diagnostic value and can accurately predict the degree of liver fibrosis in CHB patients complicated with NAFLD, thus reducing the need for liver biopsy.

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.
