Objective:To analyze the differences in routine blood tests and infection markers among elderly AIDS patients with other opportunistic infections, to explore their immune status and inflammatory responses, and to provide new molecular markers for clinical diagnosis.Methods:The study included general indicators, routine blood tests, and infection markers of older HIV patients with other opportunistic infections admitted to Beijing You'an Hospital, Capital Medical University, from January 1, 2014, to December 31, 2024.Statistical analysis was performed using SPSS 27.0 software, with a significance level set at P<0.05. Results:A total of 94 elderly AIDS patients with various opportunistic infections were included in this study.Among them, the majority were co-infected with tuberculosis, accounting for 60 cases(63.83%), followed by 23 cases(24.47%)of AIDS patients co-infected with syphilis.Additionally, there were 7 cases of AIDS co-infected with amoebiasis(7.45%)and 4 cases of AIDS co-infected with monkeypox(4.26%).Almost all cases of combined infections were male, with males comprising 91.3% of AIDS patients co-infected with syphilis and 100% in the other co-infected groups.There were 9 blood routine and infectious markers that exhibited significant differences between patients with HIV co-infected with tuberculosis and those with other opportunistic infections.These markers included lymphocytes(LYM), hemoglobin(HGB), erythrocyte sedimentation rate(ESR), C-reactive protein(CRP), procalcitonin(PCT), T lymphocytes, CD4 + T cells, CD8 + T cells, and the CD4/CD8 ratio( P<0.05).Specifically, the levels of LYM, HGB, T lymphocytes, CD4 + T cells, CD8 + T cells, and the CD4/CD8 ratio in elderly AIDS patients with tuberculosis were significantly lower than those in patients with other co-infections(all P<0.05).Conversely, the levels of inflammatory factors such as PCT, ESR, and CRP were notably higher in the former group(all P<0.05).The receiver operating characteristic(ROC)curve analysis revealed that when LYM was utilized as an individual indicator for the differential diagnosis between AIDS patients with tuberculosis and those with other opportunistic infections, the area under the curve(AUC)amounted to 0.832.However, the CRP/LYM ratio demonstrated the optimal diagnostic performance in differential diagnosis, with an AUC reaching 0.866. Conclusions:The immune function of elderly AIDS patients is further compromised following co-infection with tuberculosis, which is accompanied by a severe inflammatory response.The CRP/LYM ratio shows promise as a hematological molecular marker for differentiating between AIDS patients with tuberculosis and those with other opportunistic infections.

There is significant inter-individual variation of pharmacokinetics and pharmacody-namics in patients receiving tacrolimus(TAC)for an-ti-rejection therapy,which cause the rejection or toxic action.Based on results of therapeutic drug monitoring and pathophysiological index of trans-plant patients,the individualized dosing regimen can be designed and adjusted by using model in-formed precision dosing(MIPD).The patients'clini-cal outcome can be improved.In the consensus,the different methods of MIPD used for patients re-ceived TAC for anti-rejection therapy were intro-duced,which can be used for the designing and ad-justing doing regimen,predicting adverse drug reac-tion,improving medication adherence and econom-ics during therapy.

The incidence rate of metabolic associated fatty liver disease(MAFLD)is gradually increasing,and it has become a common chronic liver disease globally.MAFLD is closely associated with metabolic dysfunction,with dietary and exercise interventions as the primary treatment method,among which dietary control is of particular importance.This article summarizes related articles on the prevention and treatment of MAFLD through different fasting patterns in recent years,and the analysis showed that by restricting food intake and controlling calorie consumption,fasting therapy can help to reduce body weight and improve metabolic disorders.Further studies and clinical practice are needed to explore and validate the value of different fasting patterns in the prevention and treatment of MAFLD.

Canine mammary tumors are one of the most common causes of cancer-related death in female dogs,challenging traditional surgical therapies due to their high recurrence and metastasis.The natural compound Ole is strongly associated with a variety of phenomena,such as increased longevity,reduced disease incidence and mortality.However,its effect on canine mammary tumors is unclear.Therefore,the following experiments were conducted to investigate whether Ole has an effect on the development of canine mammary tumors:The effects of Ole at different concentra-tions on CHMm cell viability,migration ability,apoptosis,expression levels of corresponding pro-teins Bax and BCL-2 and mRNA expression of tumor-related genes were detected by scratch test,flow cytometry,RT-qPCR and protein western blot,and the mechanism of action was also ex-plored.The results showed that Ole activated the PI3K/AKT signaling pathway,induced phospho-rylation of related proteins,and significantly inhibited the expression levels of p-PI3K and p-AKT after applying OLE to CHMm of canine mammary tumor cells.At the same time,Ole significantly inhibited the survival,migration and proliferation of canine mammary tumor cells.In addition,the expressions of proteins Bax and BCL-2,which are closely related to apoptosis,and mRNA expres-sions of some tumor-related genes were significantly regulated,suggesting that Ole mediated PI3K/AKT signaling pathway effectively induced apoptosis of canine mammary tumor cells.This study suggests that Ole has the potential to become a key drug in the treatment of mammary canc-er,and provides a key target for the development of effective therapies against canine mammary tumors.

Objective:To investigate the effects of a single intravenous injection of low-dose esketamine during cesarean section on postpartum depression in primiparas.Methods:This study is a prospective randomized controlled trial involving 106 primiparas who underwent scheduled intrathecal anesthesia for cesarean section at Xi'an International Medical Center Hospital from January 2021 to December 2023. The participants were randomly assigned to either the control group or the observation group, with 53 women in each group, using a random number table method. Both groups received the same type and method of anesthesia. In the observation group, 5 minutes after the delivery of the fetus and the clamping of the umbilical cord, a low dose of esketamine (0.2 mg/kg, dissolved in 10 mL of 0.9% sodium chloride injection) was administered intravenously. The control group received an equivalent volume of 0.9% sodium chloride injection as a placebo. The score of the Edinburgh Postnatal Depression Scale at various postpartum time intervals (3, 7, 14, 30, and 42 days), the incidence of postpartum depression, and any adverse drug reactions occurring within 3 days postoperatively were compared between the two groups. Additionally, the score of the Visual Analog Scale (VAS) for contraction pain was assessed.Results:The scores of the Edinburgh Postnatal Depression Scale in the observation group at 3, 7, 14, 30, and 42 days postpartum were (6.23 ± 1.21), (5.82 ± 1.77), (6.14 ± 1.20), (5.33 ± 1.19), and (6.01 ± 1.23), respectively. These scores were significantly lower than those in the control group [(8.99 ± 1.28), (8.91 ± 2.11), (9.03 ± 1.94), (10.40 ± 2.68), (9.28 ± 1.84), t = 11.40, 8.16, 9.22, 12.58, 10.75, all P < 0.001]. The incidence of postpartum depression in the observation group at 7 and 14 days postpartum was significantly lower than that in the control group [3.77% (2/53) vs. 16.98% (9/53), 3.77% (2/53) vs. 15.09% (8/53), χ2 = 4.97, 3.97, P = 0.026, 0.046]. There was no statistically significant difference in the incidence of adverse drug reactions within 3 days postoperatively between the two groups of women who underwent scheduled intrathecal anesthesia for cesarean section [15.09% (8/53) vs. 11.32% (6/53), χ2 = 0.32, P = 0.566]. The scores of the Visual Analog Scale for contraction pain in the observation group at 3, 6, 12, and 24 hours postoperatively were (2.13 ± 0.28), (2.55 ± 0.33), (2.73 ± 0.35), and (3.06 ± 0.37), respectively. These scores were significantly lower than those in the control group [(4.35 ± 0.46), (5.43 ± 0.36), (5.68 ± 0.35), (5.26 ± 0.43), t = 30.01, 42.93, 43.38, 28.23, all P < 0.001]. Conclusions:A single intravenous injection of low-dose esketamine during cesarean section can effectively alleviate emotional distress in primiparas in the short term after surgery, which has significant clinical implications for reducing the incidence of postpartum depression.
