OBJECTIVE To provide a reference for the selection of anti-infection schemes and pharmaceutical monitoring of pulmonary infection due to Alternaria alternata after renal transplantation. METHODS The clinical pharmacist was involved in the anti-infective treatment of a patient with pulmonary infection caused by A. alternata after renal transplantation. After considering the patient’s clinical symptoms， laboratory test results， and pertinent literature， clinical pharmacists determined that the patient may have developed pulmonary infection as a result of respiratory allergy due to A. alternata. The potential for infections from both Legionella and adenovirus remained a possibility. Oral administration of Voriconazole tablets was recommended for fungal therapy， while Moxifloxacin tablets were suggested for treating Legionella. Additionally， it was advised to lower the dosage of tacrolimus and stop using ganciclovir. The pharmacists meticulously tracked the patient’s voriconazole trough levels and any adverse effects that might arise during the therapy. RESULTS The physician endorsed the clinical pharmacist’s recommendations， and the patient’s status was steady， permitting discharge. CONCLUSIONS A. alternata is a potential pathogen for immunosuppressed patients， particularly when they also experience respiratory allergic reactions. Voriconazole can serve as the first-line treatment for anti-infection therapy. Clinical pharmacists ensure the patient medication safety by adjusting the dosage of voriconazole， extending the treatment course， monitoring liver and visual functions， and being vigilant about the interaction between voriconazole and immunosuppressants.

ObjectiveTo investigate the influence of histone deacetylase 3 (HDAC3) on the occurrence, development of psoriasis-like inflammation in mice, and the relative immune mechanisms. MethodsHealthy C57BL/6 mice aged 6-8 weeks were selected and randomly divided into 3 groups: control group (Control), psoriasis model group (IMQ), and HDAC3 inhibitor RGFP966-treated psoriasis model group (IMQ+RGFP966). One day prior to the experiment, the back hair of the mice was shaved. After a one-day stabilization period, the mice in Control group was treated with an equal amount of vaseline, while the mice in IMQ group was treated with imiquimod (62.5 mg/d) applied topically on the back to establish a psoriasis-like inflammation model. The mice in IMQ+RGFP966 group received intervention with a high dose of the HDAC3-selective inhibitor RGFP966 (30 mg/kg) based on the psoriasis-like model. All groups were treated continuously for 5 d, during which psoriasis-like inflammation symptoms (scaling, erythema, skin thickness), body weight, and mental status were observed and recorded, with photographs taken for documentation. After euthanasia, hematoxylin-eosin (HE) staining was used to assess the effect of RGFP966 on the skin tissue structure of the mice, and skin thickness was measured. The mRNA and protein expression levels of HDAC3 in skin tissues were detected using reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot (WB), respectively. Flow cytometry was employed to analyze neutrophils in peripheral blood and lymph nodes, CD4⁺ T lymphocytes, CD8⁺ T lymphocytes in peripheral blood, and IL-17A secretion by peripheral blood CD4⁺ T lymphocytes. Additionally, spleen CD4⁺ T lymphocyte expression of HDAC3, CCR6, CCR8, and IL-17A secretion levels were analyzed. Immunohistochemistry was used to detect the localization and expression levels of HDAC3, IL-17A, and IL-10 in skin tissues. ResultsCompared with the Control group, the IMQ group exhibited significant psoriasis-like inflammation, characterized by erythema, scaling, and skin wrinkling. Compared with the IMQ group, RGFP966 exacerbated psoriasis-like inflammatory symptoms, leading to increased hyperkeratosis. The psoriasis area and severity index (PASI) skin symptom scores were higher in the IMQ group than those in the Control group, and the scores were further elevated in the IMQ+RGFP966 group compared to the IMQ group. Skin thickness measurements showed a trend of IMQ+RGFP966>IMQ>Control. The numbers of neutrophils in the blood and lymph nodes increased sequentially in the Control, IMQ, and IMQ+RGFP966 groups, with a similar trend observed for CD4⁺ and CD8⁺ T lymphocytes in the blood. In skin tissues, compared with the Control group, the mRNA and protein levels of HDAC3 decreased in the IMQ group, but RGFP966 did not further reduce these expressions. HDAC3 was primarily located in the nucleus. Compared with the Control group, the nuclear HDAC3 content decreased in the skin tissues of the IMQ group, and RGFP966 further reduced nuclear HDAC3. Compared with the Control and IMQ groups, RGFP966 treatment decreased HDAC3 expression in splenic CD4⁺ and CD8⁺ T cells. RGFP966 treatment increased the expression of CCR6 and CCR8 in splenic CD4⁺ T cells and enhanced IL-17A secretion by peripheral blood and splenic CD4⁺ T lymphocytes. Additionally, compared with the IMQ group, RGFP966 reduced IL-10 protein levels and upregulated IL-17A expression in skin tissues. ConclusionRGFP966 exacerbates psoriatic-like inflammatory responses by inhibiting HDAC3, increasing the secretion of the cytokine IL-17A, and upregulating the expression of chemokines CCR8 and CCR6.

OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.

Rhegmatogenous retinal detachment(RRD)is a vision-threatening ocular emergency with the potential risk of blindness. Pars plana vitrectomy(PPV)is the treatment of choice for RRD, especially for complex retinal detachments such as posterior pole retinal tears, grade B or higher proliferative vitreoretinopathy, and concomitant choroidal detachment. Although most patients achieve good anatomical restoration after surgery, some patients may still experience postoperative symptoms such as distorted vision, abnormal color perception, and lack of improvement in corrected visual acuity. Epiretinal membranes(ERM), as one of the most common complications after RRD, occur in 4% to 13% of cases, which not only affect the recovery of patients' postoperative vision, but also are frequently associated with visual distortion. In severe cases, a second surgical intervention may be required. In recent years, internal limiting membrane peeling(ILMP)has been introduced as an adjunctive procedure in the treatment of RRD, to facilitate retinal reorientation, reduce postoperative complications, and improve patients' postoperative visual quality and quality of life. However, previous studies on the effects of combined intraoperative ILMP on retinal anatomy and visual function recovery are limited. Therefore, this article reviews the mechanism, clinical application, challenges and research progress of ILMP in RRD, providing a reference for surgical decision making, disease assessment, and prognosis evaluation.

Conclusion Midazolam induced mitochondrial autophagy in IS rats by activating the PINK1/PARKIN signaling pathway, neuronal apoptosis was reduced and neuronal damage were improved in IS rats.

Background Indoor air quality directly affects people's health, especially the impact of chemical pollutants in residential indoor air on children and the elderly is more significant. Objective To understand the pollution status of common chemical pollutants in residential indoor air in Shijiazhuang, evaluate the health risks of chemical pollutants to school-age children and the elderly, and provide reference for controlling indoor pollution in residential environment. Methods Using stratified random sampling, a total of 60 households were selected from 2 urban areas and 1 surrounding rural area in Shijiazhuang City, specifically in July 2023 (non-heating season) and December 2023 (heating season), respectively. Relevant data was collected through on-site sampling [including CO, CO₂, PM₁₀, PM_2.5, NO₂, SO₂, O₃, ammonia, formaldehyde, benzene, toluene, xylene, total volatile organic compounds (TVOC), trichloroethylene, and tetrachloroethylene] and survey questionnaires. The pollutant concentrations were evaluated following the Standards for indoor air quality of GB/T 18883-2022, and the inhalation exposure risks of the target population were assessed based on the health risk assessment method. Results In the indoor air of the urban and rural residence in Shijiazhuang City, except for CO, NO₂, SO₂, toluene, and xylene, which did not exceed the standard limits, other pollutants showed varying degrees of exceedance. The non-qualified rates of PM₁₀, PM_2.5, and CO₂ in the urban areas were higher than those in the rural areas (P < 0.05). The seasonal difference analysis showed that the non-qualified rates of PM_2.5, PM₁₀, CO₂, trichloroethylene, and tetrachloroethylene in the urban areas were higher in the heating season than in the non-heating season (P<0.05); the non-qualified rates of ammonia and formaldehyde in the rural areas increased significantly in the non-heating season(P<0.05). The health risk assessment indicated that the maximum hazard quotient (HQ) of tetrachloroethylene for the elderly exceeded 1, while the HQ values for ammonia, formaldehyde, benzene, toluene, xylene, and trichloroethylene remained below 1 for either children or the elderly. For carcinogenic risks, the median carcinogenic risk (CR) of formaldehyde for school-aged children or the elderly fell within the range of 10⁻⁶-10⁻⁴, whereas the median CR values for benzene, trichloroethylene, and tetrachloroethylene were all below 10⁻⁶. Conclusion The primary indoor air pollutants exceeding the national standard limits in residential areas of Shijiazhuang City include CO₂, PM₁₀, TVOC, PM_2.5, formaldehyde, ammonia, trichloroethylene, and tetrachloroethylene. The levels of these pollutants exhibit significant urban-rural and seasonal variations. Special attention should be paid to the non-carcinogenic risk of tetrachloroethylene to the elderly and the carcinogenic risks of formaldehyde to school-age children and the elderly.

ObjectiveTo analyze the epidemiological trends and characteristics of brucellosis in humans (hereinafter referred to as brucellosis) in Tangshan City, Hebei Province from 2016 to 2023, and to provide a scientific basis for formulating brucellosis prevention and control strategies in the region. MethodsThe incidence data of human brucellosis in Tangshan City from 2016 to 2023 were collected from the China Disease Prevention and Control Information System. The diagnosis time, infection route, and clinical characteristics of the cases were obtained from the case investigation reports. Descriptive epidemiological methods were used to analyze the temporal, spatial, demographic distributions, and clinical characteristics of human brucellosis. Brucella species were identified using agglutination tests with bacterial suspension and A/M antigen-positive serum. ResultsA total of 2 193 cases of human brucellosis were confirmed and clinically diagnosed in Tangshan City from 2016 to 2023, with the peak incidence occured from March to August, and which exhibited distinct geographic distribution patterns. The highest incidence rate was found in people aged 60‒<70 years. The occupation of cases were primarily farmers. The incidence rate in males (528/100 000) was higher than that in females (184/100 000). All cases had confirmed exposure to infected animals or contaminated animal products. ConclusionThe epidemic of human brucellosis in Tangshan exhibited an overall steady downward trend from 2016 to 2023, except for a slight increase in 2016 and 2021, with the incidence rate controlled at 289/100 000‒335/100 000. The prevention and control situation of human brucellosis still remains severe, with the highest incidence rate in the eastern region of Tangshan, which are characterized by the breeding, slaughtering, and processing of cattle and sheep. Therefore, it it is necessary to enhance the prevention and control of human brucellosis among the personnel engaged in these industries in the eastern areas.

OBJECTIVE To explore the improvement effect and mechanism of salidroside on radiation-induced parotid gland injury in rats. METHODS Rats were randomly assigned into normal group， radiation group， salidroside low-dose （salidroside-L， 50 mg/kg） group， salidroside high-dose （salidroside-H， 100 mg/kg） group， and salidroside-H+inhibitor （100 mg/kg salidroside+0.1 µmol/kg H-89） group， with 10 rats in each group. Except for the normal group， rats in the other groups were subjected to radiation exposure to establish a model of radiation-induced parotid gland injury. Rats in each group were intraperitoneally injected with the corresponding drug or normal saline， once a day， for 40 consecutive days. After the last administration， the levels of reactive oxygen species （ROS）， cyclic adenosine monophosphate （cAMP）， superoxide dismutase （SOD）， and amylase in serum were detected； the pathological changes of parotid gland tissue were observed； the apoptosis rate of parotid gland tissue cells， the expression levels of B-cell lymphoma-2 （Bcl-2） and its associated X protein （Bax）， mRNA expression levels of interleukin-6 （IL- 6） and tumor necrosis factor-α （TNF-α）， the protein expression levels of type Ⅲ collagen （Col Ⅲ）， vasoactive intestinal peptide （VIP）， and the phosphorylation level of protein kinase A （PKA） in parotid gland tissue were determined. RESULTS Compared with normal group， the levels of ROS， amylase， apoptosis rate， Bax expression level， mRNA expression levels of IL-6 and TNF- α， and protein expression level of Col Ⅲ in the radiation group were significantly increased， while the levels of cAMP， SOD， Bcl-2 expression level， VIP protein expression level and PKA phosphorylation level were significantly decreased （P＜0.05）. Compared with radiation group， the above indicators in the salidroside-L group and salidroside-H group were significantly improved （P＜0.05）， and the improvement in the salidroside-H group was more significant （P＜0.05）； inhibitor H-89 significantly reversed the changes in the above indicators of the salidroside-H group （P＜0.05）. CONCLUSIONS Salidroside can effectively alleviate radiation-induced parotid gland injury in rats， and its mechanism may be related to the activation of the VIP-cAMP pathway.

AIM: To investigate the correlation of serum C-reactive protein(CRP)-to-albumin(ALB)ratio(CAR)and neutrophil-to-lymphocyte count ratio(NLR)with pathological staging and prognosis of retinopathy of prematurity(ROP), and the predictive value of its combined testing for the prognosis of infants.METHODS:Prospective study. A total of 147 children with ROP who were born in our hospital from March 2022 to September 2024 were served as the ROP group, and 100 premature infants without ROP were served as the control group in the same period. Fully automatic biochemical analyzer was used to detect serum CRP and ALB; the flow cytometry nucleic acid fluorescence staining was used to count neutrophils and lymphocytes, and the CAR and NLR were calculated. Spearman correlation was used to analyze the relationship of serum CAR and NLR with ROP staging. Logistic regression was used to analyze the factors affecting the prognosis of children with ROP. ROC curve was drew to analyze the predictive value of serum CAR and NLR for the prognosis of ROP.RESULTS: There was comparability between the ROP group and the control group. The ROP group had significantly higher serum CRP, CAR, neutrophil count, and NLR than the control group, and clearly lower ALB and lymphocyte count than the control group(all P<0.05). Children with stage IV ROP had clearly higher serum CAR and NLR than stages I, II, and III, and the differences among stages I, II, and III were significant(all P<0.05). Serum CAR and NLR were positively correlated with ROP staging(r=0.529, 0.587, all P<0.05), and there was a positive correlation between serum CAR and NLR(r=0.546, P<0.05). The poor prognosis group had clearly higher serum CAR and NLR than good prognosis group(all P<0.001). Elevated serum CAR and NLR were risk factors affecting the prognosis of children with ROP(all P<0.05). The AUC of serum CAR, NLR, and joint detection in predicting the prognosis of ROP children was 0.803, 0.825, and 0.938, respectively. The joint detection showed better predictive performance(Zcombinatoion-CAR=2.637, Zcombinatoion-NLR=2.528, all P<0.05).CONCLUSION:Serum CAR and NLR are elevated in children with ROP, and they are closely related to pathological staging and prognosis. The joint detection has a higher predictive value in evaluating the prognosis of ROP.
