[Objective] To explore the predictive value of HALP score for prognosis in patients with multiple myeloma (MM). [Methods] A retrospective analysis was conducted on laboratory indicators and related clinical data of newly diagnosed multiple myeloma (NDMM) patients, treated at the Affiliated Hospital of North Sichuan Medical College from January 2016 to October 2023, prior to their first treatment. The HALP score was calculated, and the optimal cutoff value for HALP was determined using X-tile software. Survival analysis was performed using Kaplan-Meier curves for high HALP and low HALP groups. Univariate and multivariate analyses were conducted using the Cox regression model, and a forest plot was generated using Graphpad Prism to illustrate factors that may impact patient prognosis. The predictive ability of HALP score combined with β2-microglobulin and ECOG score for prognosis in MM patients was evaluated using receiver operating characteristic curve (ROC) analysis. [Results] A total of 203 MM patients were included, with the optimal cutoff value for HALP score being 29.15 (P<0.05). Among them, 101 patients were in the low HALP score group, and 102 patients were in the high HALP score group. The results of univariate and multivariate analysis using the Cox regression model showed that a HALP score <29.15 was an independent risk factor for progression-free survival (PFS) and overall survival (OS) (P<0.05). ROC curve analysis indicated that the combination of HALP score with β2-microglobulin and ECOG score had a higher predictive value for prognosis in MM patients compared to using HALP score alone. [Conclusion] The HALP score is closely related to the prognosis of patients with NDMM. A low HALP score indicates a poorer prognosis, while the combination of HALP score with β2-microglobulin and ECOG score provides a higher predictive value when assessed together.

OBJECTIVE To observe the short-term efficacy and safety of venetoclax combined with homoharringtonine and cytarabine in the treatment of acute myeloid leukemia （AML）. METHODS The data of 40 newly diagnosed AML patients admitted to our hospital from October 2022 to November 2023 were retrospectively collected and divided into observation group and control group according to treatment plan， with 20 cases in each group. The patients in the control group were given Daunorubicin hydrochloride for injection+Cytarabine for injection， and the patients in the observation group were given Venetoclax tablets+ Homoharringtonine injection+Cytarabine for injection. The patients in both groups were given relevant medicine， with 28 days as one cycle. The short-term efficacy， negative rate of minimal residual disease （MRD）， duration of granulocyte deficiency， duration of platelet （PLT） ＜20×109 L－1， transfusion volume of suspended red blood cells and platelet， and the occurrence of adverse drug reactions were evaluated in both groups after 1 cycle of induction chemotherapy. RESULTS The complete remission or complete remission with incomplete hematologic recovery （CR/CRi） rate in the observation group was significantly higher than control group （P＜0.05）， and the negative rate of MRD in the observation group was also significantly higher than control group （P＜0.05）. However， in low-， medium- and high-risk patients， there was no statistical significance in CR/CRi rates between the two groups （P＞0.05）. There were no significant differences in the duration of agranulocytosis， the duration of PLT ＜20×109 L－1， the amount of suspended red blood cell transfusion， the amount of platelet transfusion， the incidence of hematologic toxicity and the incidence of non-hematologic toxicity between 2 groups （P＞0.05）. CONCLUSIONS Venetoclax combined with homoharringtonine and cytarabine show good short-term efficacy and safety in the treatment of AML.

Objective To assess the effect of platycodin D(PD)for alleviating pulmonary fibrosis in mice and explore the underlying mechanism.Methods C57BL/6J mouse models of pulmonary fibrosis induced by bleomycin injection into the airway were treated with daily intragastric administration of 10 mg/kg PD for 28 days.The changes of pulmonary fibrosis and the expression and distribution of transient receptor potential cation channel subfamily C member 6(TRPC6)were evaluated with immunohistochemistry,HE staining and Sirius Red staining.Western blotting was used to detect α-SMA expression in the lung tissues of the mice.Primary cultures of mouse lung fibroblasts were pretreated with PD(2.5,5.0,and 10 μmol/L)or larixyl acetate(LA;10 μmol/L)before exposure to 10 ng/mL transforming growth factor-β1(TGF-β1),and the changes in cell survival rate,expressions of collagen I,α-SMA and TRPC6,reactive oxygen species(ROS)production,mitochondrial membrane potential,and cell proliferation capacity were assessed.Network pharmacology analysis was performed to explore the mechanism by which PD alleviated pulmonary fibrosis.Results PD treatment significantly alleviated pulmonary fibrosis and reduced α-SMA expression in BLM-induced mouse models(P<0.05).In TGF-β1-induced primary mouse lung fibroblasts,PD effectively inhibited the cell proliferation,reduced ROS production(P<0.0001),rescued the reduction of mitochondrial membrane potential(P<0.001),and inhibited the expressions of α-SMA and collagenⅠ(P<0.05).Network pharmacology analysis suggested that TRPC6 mediated the effect of PD for alleviating pulmonary fibrosis.Immunohistochemistry showed that PD significantly reduced TRPC6 expression in the lung tissues of BLM-induced mice.In primary mouse lung fibroblasts,PD significantly inhibited TGF-β1-induced TRPC6 expression(P<0.05),and LA treatment obviously lowered the expression levels of TRPC6,α-SMA and collagenⅠ(P<0.05).Conclusion PD alleviated pulmonary fibrosis in mice possibly by down-regulating TRPC6 and reducing ROS production.

Objective To explore the impact of predictive nursing intervention under the guidance of the"5S"management model on the rehabilitation effect and pulmonary infection rate of hypertensive intracerebral hemorrhage patients.Methods A total of 120 patients with hypertensive intracerebral hemorrhage who were treated at the Second Affiliated Hospital of Wenzhou Medical University from January 2022 to January 2023 were selected as the research subjects.Patients were divided into a predictive nursing intervention group and a conventional nursing group using a random number table method,with 60 patients in each group.The routine nursing group received routine care,while the predictive nursing intervention group received predictive nursing intervention guided by the"5S"management model.The modified Rankin scale(mRS)was used to evaluate the patient's neurological function.The mini-mental state examination(MMSE)was used to evaluate the cognitive function of patients.The differences of mRS and MMSE scores between two groups of patients with different nursing interventions were compared,and the incidence of complications,hospital stay,and disability rate were recorded between both groups.Results After the intervention,the cognitive function score of the predictive nursing intervention group was significantly higher than before the intervention,while the neurological function score was significantly lower than before the intervention.After intervention,the cognitive function score of the predictive nursing intervention group was significantly higher than that of the conventional nursing group(28.02±2.03 vs.24.57±2.25,P＜0.05).The neurological function score was significantly lower than that of the conventional nursing group(1.55±0.67 vs.2.20±0.48,P＜0.05).The hospitalization time and disability rate in the predictive nursing intervention group were significantly lower than those in the conventional nursing group[hospitalization time(days):14.94±6.02 vs.25.33±7.03,disability rate:8.33%(5/60)vs.23.33%(14/60),both P＜0.05].The incidence of pressure injury,lung infection,and urinary system infection was significantly lower than that of the conventional nursing group[pressure injury:1.67%(1/60)vs.10.00%(6/60),lung infection:1.67%(1/60)vs.11.67%(7/60),urinary system infection:0%(0/60)vs.6.67%(4/60),all P＜0.05].Conclusions Under the guidance of the"5S"management model,predictive nursing can significantly improve postoperative cognitive and neurological dysfunction in patients with hypertensive cerebral hemorrhage,reduce disability rates,shorten hospital stay,and reduce the incidence of complications such as pulmonary infections.It has good clinical application prospects.

Objective:To investigate the characteristics of multimodal ultrasound imaging in elderly hyperlipidemia patients with statin-related myopathy and to provide a reference of new method for non-invasive quantitative evaluation on statin myopathy.Methods:We collected 20 elderly hyperlipidemia patients with statin-related myopathy(the statin-related myopathy group), 20 elderly hyperlipidemia patients without statin-related myopathy after taking statins during the same period(the non-statin-related myopathy group), and 20 healthy volunteers who matched the age and sex of the above two groups during the same period(the healthy control group)in our hospital.Two-dimensional ultrasound, shear wave elastography and superb microvascular imaging were used to obtain thickness, echo, pinnation angle and shear wave velocity(SWV)values as well as vascular index(VI)values of the medial gastrocnemius during relaxation, dorsiflexion, and plantar flexion for each group, which were then analyzed.Results:There were no significant differences among the three groups in general conditions such as age, height, weight, and body mass index(all P>0.05). The mean thickness of the medial gastrocnemius in the statin-related myopathy group was about(1.04 ± 0.20)cm, which was less than(1.34 ± 0.16)cm in the non-statin-related myopathy group and(1.35 ± 0.15)cm in the healthy control group( F=22.03, P<0.001). The pinnation angle in the statin-related myopathy group was about(12.50 ± 1.10), which was less than(18.55 ± 1.28)in the non-statin-related myopathy group and(18.60 ± 1.35)in the healthy control group( F=158.03, P<0.001). Compared with the non-statin-related myopathy group and the healthy control group, SWV during resting, dorsiflexion and plantar flexion in the statin-related myopathy group decreased( F=61.71, 111.96 and 8.69, respectively, P<0.01). The average value of VI in the statin-related myopathy group was about(0.43 ± 0.12)%, which was less than that in the non-statin-related myopathy group(0.75 ± 0.20)% and in the healthy control group(0.93 ± 0.17)%( F=48.93, P<0.001). However, there was no significant difference in values from the parameters between the non-statin-related myopathy group and the healthy control group(all P>0.05). Conclusions:Multimodal ultrasound imaging of statin-related myopathy in elderly hyperlipidemia patients shows distinct characteristics and can be used to evaluate muscle damage of statin-related myopathy.

Early childhood caries (ECC) is a significant chronic disease of childhood and a rising public health burden worldwide. ECC may cause a higher risk of new caries lesions in both primary and permanent dentition, affecting lifelong oral health. The occurrence of ECC has been closely related to the core microbiome change in the oral cavity, which may be influenced by diet habits, oral health management, fluoride use, and dental manipulations. So, it is essential to improve parental oral health and awareness of health care, to establish a dental home at the early stage of childhood, and make an individualized caries management plan. Dental interventions according to the minimally invasive concept should be carried out to treat dental caries. This expert consensus mainly discusses the etiology of ECC, caries-risk assessment of children, prevention and treatment plan of ECC, aiming to achieve lifelong oral health.

Few studies have described the key features and prognostic roles of lung microbiota in patients with severe community-acquired pneumonia (SCAP). We prospectively enrolled consecutive SCAP patients admitted to ICU. Bronchoscopy was performed at bedside within 48 h of ICU admission, and 16S rRNA gene sequencing was applied to the collected bronchoalveolar lavage fluid. The primary outcome was clinical improvements defined as a decrease of 2 categories and above on a 7-category ordinal scale within 14 days following bronchoscopy. Sixty-seven patients were included. Multivariable permutational multivariate analysis of variance found that positive bacteria lab test results had the strongest independent association with lung microbiota (R² = 0.033; P = 0.018), followed by acute kidney injury (AKI; R² = 0.032; P = 0.011) and plasma MIP-1β level (R² = 0.027; P = 0.044). Random forest identified that the families Prevotellaceae, Moraxellaceae, and Staphylococcaceae were the biomarkers related to the positive bacteria lab test results. Multivariable Cox regression showed that the increase in α-diversity and the abundance of the families Prevotellaceae and Actinomycetaceae were associated with clinical improvements. The positive bacteria lab test results, AKI, and plasma MIP-1β level were associated with patients' lung microbiota composition on ICU admission. The families Prevotellaceae and Actinomycetaceae on admission predicted clinical improvements.
