Objective:To retrospectively analyze the changes in the proportion of refined lymphocyte subsets in peripheral blood of patients with Graves disease (GD), and their correlation with the clinical characteristics and efficacy of GD, and to explore the immunological pathogenesis of Graves disease for seeking new therapeutic targets.Methods:A total of 97 newly diagnosed GD patients (GD group), 27 patients after treatment (treatment group), and 31 healthy individuals (control group) who visited the Fifth Medical Center of the PLA General Hospital from 2018 to 2021 were included in this study. The data of refined lymphocyte subsets, thyroid function, blood routine and clinical treatment of the three groups were compared and analyzed. The t-test and rank sum test were used to compare the proportions of lymphocyte subsets among different groups, and Pearson correlation analysis was used to analyze the correlation between the proportions of lymphocyte subsets and thyroid function indicators.Results:The proportion of B cells in GD group was higher than that in the control group [16.2%(11.8%, 21.8%) vs 10.2%(8.1%,13.6%)], while the proportion of natural killer (NK) cells was lower [9.4%(4.9%, 13.6%) vs 14.6%(12.1%,18.8%)], and the differences were statistically significant ( P<0.05). Abnormal T cell differentiation: the proportions of functional cells, including activated T cells, memory T cells, clustering antigen(CD)4+memory T cells, Th1 cells, and Tc1 cells, were lower than that in the control group [3.2%(2.1%, 5.7%) vs 5.8%(3.0%, 9.3%), P<0.05; 36.7% (29.9%, 48.1%) vs 48.0%(39.2%,57.7%), P<0.05; 23.1%(17.4%, 30.1%) vs 28.9%(23.3%,34.6%), P<0.05; 16.4% (11.8%, 23.6%) vs 24.3%(16.9%,28.5%), P<0.05; 28.5% (14.7%, 39.2%) vs 46.3%(21.6%,69.2%), P<0.05]. The proportion of activated T cells in the treatment group was higher than that in the GD group [6.5% (4.6%, 13.6%) vs 3.2% (2.1%, 5.7%), P<0.05]. The total triiodothyronine results showed positive correlations with B cells ( r=0.356, P<0.01) and negative correlations with NK cells ( r=?0.416, P<0.01), while the total thyroxine values showed negative correlations with NK cells and activated T cells ( r=?0.318,?0.335; P<0.01). Thyroid stimulating hormone and CD8+initial T cells were positively correlated ( r=0.382, P<0.01). The proportion of B cells, cytotoxic T cells and suppressor T cells in CD8+cells of patients with complications [such as Graves orbitopathy (GO), thyroid toxic cardiomyopathy, etc.] was significantly different from that of the simple GD patients [18.3% (14.1%, 27.1%) vs 14.6% (10.8%, 21.4%), Z=2.54, P<0.05; 73.4%(65.6%,83.6%)vs 65.0%(50.3%,79.3%), Z=2.93, P<0.05; 26.6%(16.4%, 37.5%)vs 35.0%(20.7%,49.7%), Z=?2.74, P<0.05]. The proportion of suppressor T cells in GO patients was lower than that in non-GO patients [6.1% (3.4%, 8.1%) vs 8.5% (4.9%, 13.6%), Z=?3.20 P<0.05]. Conclusion:There are significant alterations in the circulating immune cells of GD patients, suggesting that immunological abnormalities play a crucial role in the onset and progression of the disease.

Objective To investigate the protective effect and regulatory mechanism of ciprofol on Parkinson's disease(PD)rats based on the adenosine monophosphate-activated protein kinase(AMPK)/silent information regulator 1(SIRT1)/peroxisome proliferator-activated receptor gamma coactivator 1α(PGC1α)signaling pathway.Methods Wistar rats were divided into blank control group,model group,ciprofol group,and ciprofol+AMPK inhibitor dorsomorphin group(ciprofol+Dor group),with 10 rats in each group.Except for the blank control group,PD models were estab-lished in the other three groups.Behavioral experiments were used to assess the motor and cognitive functions of rats in each group.Enzyme-linked immunosorbent assay(ELISA)was employed to de-tect the levels of dopamine(DA)and 5-hydroxytryptamine(5-HT)in the rat brain striatum.Immu-nofluorescence staining was conducted to measure the level of tyrosine hydroxylase(TH)in the rat brain substantia nigra.Real-time fluorescence quantitative polymerase chain reaction(RT-qPCR)was applied to detect the relative mRNA expression levels of ULK1,beclin1,LC3,Bcl-2,and Bax in the rat brain striatum.Western blot was used to determine the relative protein expression levels of ULK1,beclin1,Bcl-2,Bax,phosphorylated(p)-AMPK,SIRT1,PGC1α,and the ratio of LC3 Ⅱ to LC3 Ⅰ(LC3 Ⅱ/LC3 Ⅰ)in the rat brain striatum.Results Compared with the blank control group,the motor and cognitive functions of rats in the model group were reduced,the levels of DA and 5-HT in the brain striatum decreased,the fluorescence intensity of TH in the brain substantia nigra weakened,and the relative mRNA expression levels of ULK1,beclin1,LC3,Bcl-2,as well as the relative protein expression levels of ULK1,beclin1,Bcl-2,p-AMPK,SIRT1,PGC1α,and LC3 Ⅱ/LC3 Ⅰ in the brain striatum were reduced.In contrast,the relative mRNA expression level of Bax and the relative protein expression level of Bax increased,with statistically significant differ-ences(P＜0.05).Compared with the model group,the motor and cognitive functions of rats in the ciprofol group were improved,the levels of DA and 5-HT in the brain striatum increased,the fluo-rescence intensity of TH in the brain substantia nigra strengthened,and the relative mRNA expres-sion levels of ULK1,beclin1,LC3,Bcl-2,as well as the relative protein expression levels of ULK1,beclin1,Bcl-2,p-AMPK,SIRT1,PGC1α,and LC3 Ⅱ/LC3 Ⅰ in the brain striatum were elevated.Meanwhile,the relative mRNA expression level of Bax and the relative protein expression level of Bax decreased,with statistically significant differences(P＜0.05).The comparison between the ciprofol+Dor group and the ciprofol group revealed that the AMPK inhibitor dorsomorphin could re-verse the effects of ciprofol(P＜0.05).Conclusion Ciprofol may exert neuroprotective effects for PD rats by promoting autophagy through activating the AMPK/SIRT1/PGC1α signaling pathway.

Objective To investigate the effects and related molecular mechanisms of esket-amine on the proliferation,epithelial-mesenchymal transition(EMT),and stem cell properties of colorectal cancer(CRC)cells.Methods CRC cell line SW480 was cultured with varying concentra-tions of esketamine,and the cells were divided into blank group(0 μmol/L),low-concentration group(1 μmol/L),medium-concentration group(5 μmol/L)and high-concentration group(10 μmol/L).Cell proliferation activity was assessed using the EdU proliferation assay,cell spheroid-forming ability was evaluated via the spheroid formation assay,cell migration capacity was measured using the scratch assay,cell invasion ability was determined through the transwell assay,and the expression levels of tumor stem cell property markers[NANOG homeobox(NANOG),SRY-box transcription fac-tor(SOX)2,SOX4],the neurogenic locus Notch homolog protein 1(Notch1)receptor and the Notch1 intracellular domain(Notch1 ICD)were detected by western blot.A recovery test was con-ducted by adding the Notch1 receptor agonist Jagged1 to the culture groups with different concentra-tions of esketamine.Results Compared with the blank group,esketamine significantly inhibited the proliferation activity,spheroid-forming ability,migration ability,and invasion ability of CRC cells in a concentration-dependent manner.The intracellular expression levels of SOX2,SOX4,NANOG,and Notch1 ICD proteins were significantly decreased,while the expression level of the Notch1 recep-tor was significantly increased in the esketamine groups(P＜0.05).After the addition of Jagged1,the inhibitory effects of esketamine on the proliferation activity,metastatic ability,and stem cell properties of CRC cells were alleviated.Conclusion Esketamine inhibits CRC cell proliferation,metastasis,EMT,and stem cell properties by reducing the activation level of the Notch1 receptor,demonstrating a potential for clinical anti-tumor applications.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective　To analyze the causes of death of one case of imported falciparum malaria in Guangxi Zhuang Autonomous Region in January 2023, to provide a reference for the prevention of fatal malaria cases. Methods Interviews were conducted with the doctors who received and consulted the patient, as well as the family members of the patient. Clinical data from the patient's diagnosis and treatment process were collected, and the patient's clinical records and epidemiological investigation data were analyzed. Results The patient, Mr. He, a 53-year-old male from Pingnan County, Guigang City, Guangxi Zhuang Autonomous Region, returned from working in Côte d'Ivoire, Africa, and entered Guangxi on December 26, 2022. He returned home after his centralized quarantine was lifted on January 3, 2023. On January 4th, 2023, the patient developed dizziness and vomiting, considering himself to a possible COVID-19 infection, he did not seek treatment. On the morning of January 6, the patient developed a fever (peak body temperature of 40 ℃), accompanied by fatigue and sore throat, and the preemptive symptoms were aggravated. The patient was admitted to the Guancheng Town Health Center with "Pneumonia" and treated with ribavirin, dexamethasone, ceftriaxone sodium, etc. On January 7, the patient again experienced a high fever (40 ℃) and was discharged to the Emergency Department of the First Affiliated Hospital of Guangxi Medical University. Upon admission, the patient's blood pressure was measured at 78/53mmHg, further comprehensive examination showed a decrease in platelets and abnormalities in liver and renal function, procalcitonin levels at 49.9 ng/mL. Chest CT showed pneumonia, and fluid supplements and antibiotics were given. On January 8, malaria parasites were found in the patient's blood smear, and the patient was diagnosed with malaria (not classified, confirmed as falciparum malaria on January 9th). The patient was recommended to transfer to the provincial malaria-designated hospital, but his family refused. On January 8 at 13:27, the patient excreted approximately 700 g of dark red bloody stools accompanied by blurred consciousness and received hemostasis treatment. After coordinating with multiple parties, four doses of "artemisinin injection " (60 mg/dose) were taken for treatment. At 18:59 on January 8, intravenous administration of 60 mg injectable Artesunate was given, accompanied by symptomatic treatment for fever reduction and rehydration. At 19:40, the patient developed severe hypoglycemia, and severe metabolic acidosis, and blood pressure continued to decrease despite the use of vasopressors. After comprehensive treatment at 3:00 am on January 9, the patient's condition continued to deteriorate, the patient's shock could not be corrected, he lapsed into a coma, and the family requested to be discharged from the hospital. The patient returned home at 7:00 am and died of multiple organ failure at 7:30 am. Conclusions For imported malaria, early and precise diagnosis based on epidemiological history, clinical symptoms, laboratory test results, early antimalarial treatment, and management of organ dysfunction are the keys to avoiding fatal outcomes.

OBJECTIVE：To explore the role of clinical pharm acists in anti-infective therapy in patients with septic shock in the ICU. METHODS ：A total of 180 patients with septic shock were retrospectively collected from ICU of Chongqing Qianjiang Central Hospital during Jan.-Dec. 2018. According to whether clinical pharmacists participated in anti-infective therapy in the whole process，the patients were divided into intervention group （92 cases）and control group （88 cases）. Both groups were given routine treatment according to clinical diagnosis ；on this basis ，clinical pharmacists participated in the whole anti-infective therapy of the intervention group ，including participating in pharmaceutical rounds ，formulating anti-infective programs ，guiding nurses to implement anti-infective plan ，and providing pharmaceutical care for patients. The effectiveness ，safety and antibiotics clinical use indexes（such as proportion ，treatment course and cost of key monitored drugs ）were evaluated in 2 groups. RESULTS ：The cure rate of intervention group （98.91％）was significantly higher than that of control group （93.18％），while the incidence of ADR in the intervention group （8.70％）was significantly lower than control group （23.86％）. The use of antibiotics types was more rational（the proportion of carbapenems used in intervention group and control group were 20.65％，36.36％；those of quinolones were 15.22％，28.41％，respectively）；the duration of antibiotics use in the intervention group [ （15.18±2.25）d] was significantly shorter than control group [ （19.84±3.81）d]. The cost of antibiotics per capita [ （2 846.99±712.48）yuan] was significantly lower than control group [ （3 991.26±577.82）yuan]，with statistical significance of all above （P＜0.05 or P＜0.01）. CONCLUSIONS ： Clinical pharmacists participating in the anti-infective treatment of ICU patients with septic shock and providing pharmaceutical care，can improve the anti-infective effect ，reduce adverse drug reactions and drug-induced diseases ，optimize the use of antibiotics and reduce medical cost.
