ObjectiveTo study the clinical characteristics and influencing factors of rheumatoid arthritis （RA） in the patients with cold dampness obstruction syndrome. MethodsThe RA patients treated in the Department of Traditional Chinese Medicine and Rheumatology of the China-Japan Friendship Hospital from August 2022 to June 2024 were selected. The demographic information， clinical data， laboratory test results， and traditional Chinese medicine （TCM） symptom information were collected for syndrome differentiation， on the basis of which the characteristics and influencing factors of cold dampness obstruction syndrome were analyzed. ResultsA total of 258 RA patients were selected in this study， including 88 （34.1%） patients with cold dampness obstruction syndrome， 53 （20.5%） patients with dampness and heat obstruction syndrome， 31 （12.0%） patients with wind dampness obstruction syndrome， 29 （11.2%） patients with liver-kidney deficiency syndrome， 19 （7.4%） patients with Qi-blood deficiency syndrome， 14 （5.4%） patients with phlegm-stasis obstruction syndrome， 15 （5.8%） patients with stasis obstructing collateral syndrome and 9 （3.5%） patients with Qi-Yin deficiency syndrome. The patients were assigned into two groups of cold dampness obstruction syndrome and other syndromes. The group of cold dampness obstruction syndrome had lower joint fever， 28-tender joint count （TJC28）， and 28-joint disease activity score （DAS28）-C-reactive protein （CRP） and higher central sensitization， cold feeling of joints， fear of wind and cold， cold limbs， and abdominal distention than the group of other syndromes （P<0.05）. The binary logistic regression analysis showed that central sensitization （OR 5.749， 95%CI 2.116-15.616， P<0.001） and DAS28-CRP （OR 0.600， 95% CI 0.418-0.862， P=0.006） were the independent factors influencing cold dampness obstruction syndrome in RA. ConclusionCold dampness obstruction syndrome is a common syndrome in RA patients. It is associated with central sensitization， cold feeling of joints， abdominal distension and may be a clinical syndrome associated with central sensitization.

Aldehyde dehydrogenase 2 (ALDH2) is one of important factors against from the damage under oxidative stress in human body. A high proportion of East Asians carry ALDH2 inactive mutation gene. There are many diseases closely related to ALDH2, such as cardiovascular diseases, neurodegenerative diseases and liver diseases. Recent studies also have found that ALDH2 is associated with ferroptosis. Therefore, ALDH2 has becoming a potential target for the treatment of the above related diseases. Several types of small molecule activators with potential value of clinical application have been reported. The research progress on the structure and function of ALDH2 , the relationship with human diseases and its activators were summarized in this paper.

Objective To study the relationship between serum neuron-specific enolase(NSE)and clinical features of pheochromocytoma/paraganglioma(PPGL).Methods Totally 501 PPGL patients diagnosed from January 2019 to December 2022 were divided into normal NSE group(NSE≤16.3 ng/mL)and elevated NSE group(NSE＞16.3 ng/mL).The clinical characteristics were compared between the two groups.Results Compared with normal NSE group,patients in the elevated NSE group had larger diameter in primary tumor(5.00 cm vs.4.60 cm),higher 24-hour urinary norepinephrine(NE)and 24-hour urinary dopamine(DA)levels,and a higher rate of metasta-sis(31.6%vs.13.7%)(P＜0.05).NSE level was positively correlated with the primary tumor size(r=0.131,P＜0.05),24-hour urinary NE level(r=0.195,P＜0.05)and 24-hour urinary DA level(r=0.119,P＜0.05).Conclusions The level of NSE is related to tumor size,secretion function and metastasis in PPGL patients.

Objective:To test the reliability and validity of the general procrastination scale (GPS) in the application of middle school students.Methods:The Chinese version of GPS, the irrational procrastination scale(IPS), and the Maslach burnout inventory(MBI) were utilized to survey 10 825 middle school students in Harbin City through stratified random sampling, and 4 498 students were retested after 4 weeks. Statistical analysis was performed using SPSS 27.0 and Mplus 8.0.Results:The entries were well differentiated.Exploratory and confirmatory factor analysis indicated that GPS was composed of two factors, including active avoidance and lack of planning.The model fit was good (CFI=0.914, TLI=0.901, RMSEA=0.069, SRMR=0.072). GPS was positively correlated with the total scores of IPS and MBI ( r=0.753, 0.677, both P<0.001). The Cronbach's α coefficient of GPS was 0.864, the folded half reliability was 0.870, and the retest reliability after 4 weeks was 0.756. Conclusion:The GPS has good reliability and validity among middle school students, which provides a standard for measuring the procrastination level of middle school students and carrying out related research.

Major depressive disorder (MDD) has become an increasingly serious public health issue, characterized by high incidence and high disability rates. It often coexists with other mental health problems and physical diseases, with a significant negative impact on patients' quality of life. In clinical practice, MDD is considered a heterogeneous disease. The complexity of the pathological mechanisms and the variability in treatment responses lead to a lack of clear therapeutic targets, which complicates the treatment process. In recent years, with advancements in neuroscience, the crucial role of microglia in the pathogenesis of MDD has been revealed. As the main immune cells in the brain, microglia are not only involved in the regulation of neuroinflammation but also play important roles in neurogenesis and neuronal regulation in MDD. This article mainly discusses the role of microglia in the pathophysiological mechanisms of MDD, aiming to provide a theoretical basis for microglia as a potential target for the treatment of MDD.

Neuroimaging is increasingly widely used in the field of ADHD research,and more and more studies have shown that ADHD patients have structural abnormalities such as reduced cortical volume,thinning thickness,and reduced surface area,which are related to complex clinical symptoms and abnormal brain function in patients.However,the use of neuroimaging to identify biomarkers as an objective diagnostic tool for ADHD still faces many challenges.Multimodal studies can be used to explore the relationship between the structure and function of different brain regions in ADHD patients,and to use neuroimaging to reveal the mechanism of the evolution of clinical symptoms in the whole life cycle of ADHD patients.

Objective:To explore a continuing education program of pharmacy suitable for hospital development based on the professional elements of post competency for hospital pharmacists.Methods:Under the guidance of the thinking of continuing medical education in China, the methods of literature analysis and behavioral event interview were used to screen for the typical indicators of post competency for hospital pharmacists, and a questionnaire survey was conducted using the Likert 5-level scale, with the questionnaire revised by the methods of item analysis (such as the correlation test and the t-test) and exploratory factor analysis based on principal component analysis and promax rotation. In addition, the confirmatory factor analysis was performed for the model fitting indexes such as RMSEA and CFI and the reliability and validity of the model, and a continuing education program was implemented for hospital pharmacists based on the revised questionnaire.

The revised questionnaire showed good reliability and validity, and the degree of satisfaction with this program achieved 97.87%(367/375).Conclusions:The continuing education program based on post competency indicators and the need of hospital pharmacists is accurate and effective and can help to continuously and effectively improve the professional technical level and pharmaceutical service of pharmacists.

Objective To investigate the correlation between pre-treatment pan-immune inflammation value (PIV) and clinicopathological features in esophageal squamous cell carcinoma (ESCC) patients with postoperative adjuvant radiotherapy and evaluate its value in prognosis assessment combined with T stage. Methods A retrospective analysis was conducted on data of 85 ESCC patients with postoperative adjuvant radiotherapy in the Department of Radiation Oncology of the Affiliated Hospital of Yangzhou University from January 2019 to January 2023. The receiver operating characteristic (ROC) curve was drew to obtain the optimal cut-off value of PIV and other immune-inflammatory biomarkers. The area under the curve (AUC) and clinical applicability of PIV and other immune-inflammatory biomarkers were compared based on the ROC curve and decision curve analysis (DCA). According to the optimal cut-off value, patients were divided into high PIV group and low PIV group, and the correlation between PIV level and clinicopathological features of ESCC was evaluated. Kaplan-Meier method was used for survival analysis, the Cox proportional hazards model was used for multivariate analysis, and a risk stratification model combining PIV and T stage was established by recursive partitioning analysis (RPA). Results The optimal cut-off value of pre-treatment PIV was determined as 187.22 based on the ROC curve. The AUC of PIV was 0.679, which was greater than 0.640, 0.583, 0.656 and 0.644 of the other four immune-inflammatory biomarkers such as the systemic immune-inflammation index (SII), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and neutrophil-to-lymphocyte ratio (NLR). The 85 patients were divided into low PIV group (< 187.22, n=48) and high PIV group (≥187.22, n=37). The level of PIV was significantly correlated with tumor diameter (P < 0.05). The 3-year overall survival (OS) (75.6% versus 30.6%, P < 0.001) and 3-year disease-free survival (DFS) (56.1% versus 21.0%, P < 0.001) were significantly higher in the low PIV group than the high PIV group. Tumor diameter, T stage and PIV were independent factors affecting OS in ESCC patients (P < 0.05), and T stage and PIV were independent factors affecting DFS in ESCC patients (P < 0.05). A new staging system with three risk groups was established by the RPA stratification model based on T stage and PIV, which further improved the predictive value of prognosis compared with T stage or PIV alone. Conclusion Pre-treatment PIV is helpful in predicting the prognosis of ESCC patients with postoperative adjuvant radiotherapy, and the combination of PIV and T stage can improve the predictive value.

OBJECTIVE To study the pharmacokinetic changes in the plasma and cerebrospinal fluid of bronchial asthma model rats after the complication of Ephedra sinica and Prunus armeniaca. METHODS SD male rats were randomly divided into blank group， model group， E. sinica group （12 g/kg， calculated by raw drug， similarly hereinafter）， P. armeniaca group （6 g/kg） and E. sinica-P. armeniaca drug-pair group （12 g/kg of E. sinica+6 g/kg of P. armeniaca）， with 6 rats in each group. Except for the blank group， the bronchial asthma model was induced by spraying rats in each group with an equal volume mixture of 2% acetylcholine chloride and 0.4% histamine phosphate， once a day， for 7 d. One hour before modeling every time， rats in each group were gavaged with the corresponding drug/normal saline， once a day， for 7 d. After the final administration and provocation of asthma， blood and cerebrospinal fluid collection were performed at different time points. The plasma and cerebrospinal fluid samples were pre-treated （with geranylgeranyl as the internal standard）， and the mass concentrations of ephedrine/pseudoephedrine， methyl ephedrine and amygdalin in both samples were determined by liquid chromatography-tandem mass spectrometry. DAS 2.0 pharmacokinetic software was used to determine the main pharmacokinetic parameters through the non-atrial chamber model and to compare the changes of the pharmacokinetic parameters before and after the combination of the two drugs. RESULTS Compared with E. sinica group， cmax and AUC0-21.33 h （or AUC0-10.67 h） of ephedrine/pseudoephedrine and methyl ephedrine in the plasma and cerebrospinal fluid of rats were significantly reduced in E. sinica-P. armeniaca drug-pair group， while CLZ/F and VZ/F were significantly increased （P＜0.05 or P＜0.01）； tmax of methyl ephedrine in the cerebrospinal fluid was significantly shortened （P＜ 0.05）.Compared with P. armeniaca group， the t1/2 of amygdalin in the plasma of rats in E. sinica-P. armeniaca drug-pair group was significantly shortened， and CLZ/F was significantly increased （P＜0.01）； the tmax of bitter amygdalin in the cerebrospinal fluid was significantly shortened， and the AUC0-10.67 h， CLZ/F， and VZ/F were significantly increased （P＜0.01）. CONCLUSIONS The combination of E. sinica and P. armeniaca accelerates the absorption and elimination of ephedra alkaloids， thus reducing the accumulation of ephedra alkaloids in the bronchial asthma model rats.

AIM: To evaluate the safety and efficacy of ultrasonic cycloplasty(UCP)combined with anti-vascular endothelial growth factor(VEGF)+ panretinal photocoagulation(PRP)in the treatment of advanced neovascular glaucoma(NVG).METHODS: Retrospective study. A total of 45 patients(45 eyes)with advanced NVG who received surgery in our hospital from August 2020 to September 2022 were collected and divided into UCP+ anti-VEGF +PRP group(16 patients, 16 eyes), transscleral cyclophotocoagulation(TCP)+anti-VEGF+PRP group(20 patients, 20 eyes), UCP alone group(9 patients, 9 eyes). The intraocular pressure, pain scores, postoperative medication, effective rate, total success rate and the incidence of complications of the patients in the three groups were compared before surgery and at 1 d, 1 wk, 1 and 3 mo after surgery.RESULTS: There was no significant difference in preoperative intraocular pressure, pain scores and preoperative medication of patients in the three groups(all P>0.05). While there were statistical significance in the intraocular pressure and pain scores at 1 d, 1 wk, 1 and 3 mo after surgery(all P<0.01). The intraocular pressure of the UCP alone group(31.78±10.23 mmHg)was found to be higher than that of both the UCP+ anti-VEGF +PRP group(19.44±8.23 mmHg)and the TCP+ anti-VEGF +PRP group(20.80±10.27 mmHg)at 1 mo postoperatively(all P<0.017). The pain score of the TCP+ anti-VEGF +PRP group at 1 d and 1 wk postoperatively was higher than both the UCP+ anti-VEGF +PRP group and the UCP alone group(all P<0.017). The effective rates of UCP+ anti-VEGF +PRP group, TCP+ anti-VEGF +PRP group and UCP alone group were 81%(13/16), 75%(15/20)and 67%(6/9), respectively,(P=0.675), and the success rates were 69%(11/16), 50%(10/20), and 0(0/9), respectively(P=0.003). There was no significant difference in complications of patients in the three groups(P>0.05).CONCLUSION: UCP combined with anti-VEGF +PRP and TCP combined with anti-VEGF +PRP showed comparable efficacy in reducing intraocular pressure in advanced NVG. UCP combined with anti-VEGF+PRP was more effective in relieving pain and with no serious complications in advanced NVG. UCP alone can effectively control intraocular pressure and alleviate the pain of patients in the early postoperative period, but long-term control still requires anti-VEGF+PRP.
