OBJECTIVE To conduct a rapid and comprehensive evaluation of commonly used oral dihydropyridine calcium channel blockers (DHP CCBs) in Guangxi, and provide scientific basis for clinical medication and drug selection in medical institutions. METHODS Based on the actual drug use data of public medical institutions at the second level and above in Guangxi Zhuang Autonomous Region, and based on the national centralized collection catalog, commonly used oral DHP CCBs were selected. The Professional Committee of Evidence-based Pharmacy of the Guangxi Pharmaceutical Association organized relevant experts from multiple medical institutions in the region to conduct a quantitative scoring of the selected oral DHP CCBs from five key dimensions of pharmaceutical characteristics, effectiveness, safety, economy, and other attributes, by referring to the Quick Guideline for Drug Evaluation and Selection in Chinese Medical Institutions (the Second Edition), combined with the latest evidence-based medical research results, and widely soliciting suggestions from clinical and pharmaceutical experts. Finally, the Guangxi Expert Consensus on Rapid Comprehensive Evaluation of Oral Dihydropyridine Calcium Channel Blockers in the Treatment of Cardiovascular Disease was formulated. RESULTS A total of 30 commonly used oral DHP CCBs were selected. Among them, Amlodipine besylate tablets (Huizhi) demonstrated superior comprehensive performance (81.79 points), excelling particularly in pharmaceutical properties, effectiveness and other attributes. The compound scores of Amlodipine besylate tablets (Chongqing Yaoyou) and Amlodipine besylate tablets (Suzhou Dongrui) ranked second and third respectively, with scores of 81.66 and 81.60 points. CONCLUSIONS This consensus can provide guidance and decision-making support for the rational clinical application of oral DHP CCBs in Guangxi Region and the selection of drug directories in medical institutions.

ObjectiveTo explore the effect of timosaponin BⅡ (TBⅡ) combined with icariin (ICA) on osteoclast (OC)-osteoblast (OB) coupling and decipher the mechanism from the cellular level. MethodsThe cell counting kit-8 (CCK-8) was used to assess the effects of different concentrations of TBⅡ and different concentrations of TBⅡ+ICA on the growth of RAW264.7 cells. Soluble receptor activator of nuclear factor-κB ligand (sRANKL) was used to induce the differentiation of RAW264.7 pre-osteoclasts into osteoclasts. The cells were allocated into sRANKL, TBⅡ (1, 5, 10 μmol·L-1), and TBⅡ+ICA groups. Tartrate-resistant acid phosphatase staining was performed to assess the effects of TBⅡ and TBⅡ+ICA on osteoclast differentiation. Real-time quantitative polymerase chain reaction (Real-time PCR) was conducted to examine the effects of TBⅡ+ICA on the expression of key genes involved in osteoclast differentiation and osteoclast-derived coupling factors. The osteogenic differentiation conditioned medium mixed with osteoclast supernatant was used to induce osteogenic differentiation of MC3T3-E1 cells. Alkaline phosphatase staining and alizarin red S staining were employed to determine the effect of TBⅡ+ICA on osteogenic differentiation. Real-time PCR was employed to evaluate the effects of conditioned medium on key genes involved in osteogenic differentiation. ResultsTBⅡ at 1, 5, 10 μmol·L-1 had no significant effect on the cell survival rate. Compared with the sRANKL group, TBⅡ inhibited osteoclast differentiation in a dose-dependent manner and achieved the best effect at 10 μmol·L-1 (P<0.01). Compared with the sRANKL group, different concentrations of TBⅡ down-regulated the mRNA levels of osteoclast differentiation-related genes c-Fos, RANK, and RANKL (P<0.05). None of 10 μmol·L-1 TBⅡ, 10 μmol·L-1 TBⅡ+10-4 μmol·L-1 ICA, or 10 μmol·L-1 TBⅡ+10-3 μmol·L-1 ICA affected the viability of RAW264.7 cells. TBⅡ and/or ICA inhibited osteoclast differentiation (P<0.01), and TBⅡ + ICA had the best effect (P<0.01). Compared with the sRANKL group, TBⅡ and/or ICA down-regulated the mRNA levels of c-Fos, RANK, and RANKL (P<0.05). The single application of TBⅡ and ICA had no significant effect on the mRNA levels of Wnt10b, Cthrc1, and C3a, while TBⅡ+ICA exerted up-regulating effects (P<0.05). Compared with those in the blank group, the bone differentiation and mineralization abilities of the normal osteogenic induction group and each osteogenic induction + osteoclast supernatant group were improved (P<0.01). Compared with the blank group, the normal osteogenic induction group and the osteogenic induction + osteoclast supernatant group showed up-regulated mRNA levels of Runx2 and OCN (P<0.01). ConclusionTBⅡ+ICA can inhibit osteoclast differentiation, maintain the normal osteoclast-osteoblast coupling, and promote osteogenic differentiation.

BACKGROUND:
The role of inflammation in the development of gestational diabetes mellitus (GDM) has recently become a focus of research. The systemic immune-inflammation index (SII) and systemic inflammation response index (SIRI), novel indices, reflect the body's chronic immune-inflammatory state. This study aimed to investigate the associations between the SII or SIRI and GDM.
METHODS:
A prospective birth cohort study was conducted at Beijing Obstetrics and Gynecology Hospital from February 2018 to December 2020, recruiting participants in their first trimester of pregnancy. Baseline SII and SIRI values were derived from routine clinical blood results, calculated as follows: SII = neutrophil (Neut) count × platelet (PLT) count/lymphocyte (Lymph) count, SIRI = Neut count × monocyte (Mono) count/Lymph count, with participants being grouped by quartiles of their SII or SIRI values. Participants were followed up for GDM with a 75-g, 2-h oral glucose tolerance test (OGTT) at 24-28 weeks of gestation using the glucose thresholds of the International Association of Diabetes and Pregnancy Study Groups (IADPSG). Logistic regression was used to analyze the odds ratios (ORs) (95% confidence intervals [CIs]) for the the associations between SII, SIRI, and the risk of GDM.
RESULTS:
Among the 28,124 women included in the study, the average age was 31.8 ± 3.8 years, and 15.76% (4432/28,124) developed GDM. Higher SII and SIRI quartiles were correlated with increased GDM rates, with rates ranging from 12.26% (862/7031) in the lowest quartile to 20.10% (1413/7031) in the highest quartile for the SII ( Ptrend <0.001) and 11.92-19.31% for the SIRI ( Ptrend <0.001). The ORs (95% CIs) of the second, third, and fourth SII quartiles were 1.09 (0.98-1.21), 1.21 (1.09-1.34), and 1.39 (1.26-1.54), respectively. The SIRI findings paralleled the SII outcomes. For the second through fourth quartiles, the ORs (95% CIs) were 1.24 (1.12-1.38), 1.41 (1.27-1.57), and 1.64 (1.48-1.82), respectively. These associations were maintained in subgroup and sensitivity analyses.
CONCLUSION
The SII and SIRI are potential independent risk factors contributing to the onset of GDM.

OBJECTIVE:
To explore the construction method of a resistant multiple myeloma (MM) patient-derived xenotransplantation (PDX) model.
METHODS:
1.0×107 MM patient-derived mononuclear cells (MNCs), 2.0×106 MM.1S cells and 2.0×106 NCI-H929 cells were respectively subcutaneously inoculated into NOD.CB17-Prkdcscid Il2rgtm1/Bcgen (B-NDG) mice with a volume of 100 μl per mouse to establish mouse model. The morphologic, phenotypic, proliferative and genetic characteristics of PDX tumor were studied by hematoxylin-eosin staining, immunohistochemical staining (IHC), cell cycle analysis, flow cytometry and fluorescence in situ hybridization (FISH). The sensitivity of PDX tumor to bortezomib and anlotinib monotherapy or in combination was investigated through cell proliferation, apoptosis and in vitro and in vivo experiments. The effects of anlotinib therapy on tumor blood vessel and cell apoptosis were analyzed by IHC, TUNEL staining and confocal fluorescence microscope.
RESULTS:
MM PDX model was successfully established by subcutaneously inoculating primary MNCs. The morphologic features of tumor cells from MM PDX model were similar to those of mature plasma cells. MM PDX tumor cells positively expressed CD138 and CD38, which presented 1q21 amplification, deletion of Rb1 and IgH rearrangement, and had a lower proliferative activity than MM cell lines. in vitro, PDX, MM.1S and NCI-H929 cells were treated by bortezomib and anlotinib for 24 hours, respectively. Cell viability assay showed that the IC50 value of bortezomib were 5 716.486, 1.025 and 2.775 nmol/L, and IC50 value of anlotinib were 5 5107.337, 0.706 and 5.13 μmol/L, respectively. Anlotinib treatment increased the apoptosis of MM.1S cells (P < 0.01), but did not affect PDX tumor cells (P >0.05). in vivo, there was no significant difference in PDX tumor growth between bortezomib monotherapy group and control group (P >0.05), while both anlotinib monotherapy and anlotinib combined with bortezomib effectively inhibited PDX tumor growth (both P < 0.05). The vascular perfusion and vascular density of PDX tumor were decreased in anlotinib treatment group (both P < 0.01). The apoptotic cells in anlotinib treatment group were increased compared with those in control group (P < 0.05).
CONCLUSION
Bortezomib-resistant MM PDX model can be successfully established by subcutaneous inoculation of MNCs from MM patients in B-NDG mice. This PDX model, which retains the basic biological characteristics of MM cells, can be used to study the novel therapies.

OBJECTIVE:
The relationship between fish consumption and stroke is inconsistent, and it is uncertain whether this association varies across predicted stroke risks.
METHODS:
A cohort study comprising 95,800 participants from the Prediction for Atherosclerotic Cardiovascular Disease Risk in China project was conducted. A standardized questionnaire was used to collect data on fish consumption. Participants were stratified into low- and moderate-to-high-risk categories based on their 10-year stroke risk prediction scores. Hazard ratios ( HRs) and 95% confidence intervals ( CIs) were estimated using Cox proportional hazard models and additive interaction by relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (SI).
RESULTS:
During 703,869 person-years of follow-up, 2,773 incident stroke events were identified. Higher fish consumption was associated with a lower risk of stroke, particularly among moderate-to-high-risk individuals ( HR = 0.53, 95% CI: 0.47-0.60) than among low-risk individuals ( HR = 0.64, 95% CI: 0.49-0.85). A significant additive interaction between fish consumption and predicted stroke risk was observed (RERI = 4.08, 95% CI: 2.80-5.36; SI = 1.64, 95% CI: 1.42-1.89; AP = 0.36, 95% CI: 0.28-0.43).
CONCLUSION
Higher fish consumption was associated with a lower risk of stroke, and this beneficial association was more pronounced in individuals with moderate-to-high stroke risk.

Objective:To summarize the best evidence for exercise intervention in elderly patients with sarcopenia in intensive care unit (ICU) through literature search, and provide a reference for clinical implementation of early exercise intervention in this population through evidence-based practice.Methods:① Summary of best evidence: relevant literature on exercise intervention for elderly patients with sarcopenia in ICU, including guideline, evidence summary, expert consensus, systematic review, and original study [quasi-experiment and randomized controlled trial (RCT)] from UpToDate Clinical Advisor, Ovid database, National Guideline Clearinghouse (NGC), National Institute for Health and Care Excellence (NICE), Cochrane Library, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed/Medline, SinoMed, CNKI, Wanfang Database, VIP, and Yimai Tong Guideline Network were systematically searched. The search period covered from the establishment of these databases up to August 24, 2023. The quality of the literature was evaluated by two researchers with methodological expertise in evidence-based medicine, and the evidences were extracted and summarized. ② Evidence-based practice: the elderly patients with high risk of sarcopenia who had been hospitalized in the ICU for more than 7 days from January to April 2024 were enrolled as the research subjects, and they were divided into a control group and an intervention group using convenience sampling method. The control group received routine intensive care nursing. The intervention group implemented exercise intervention based on the actual situation of the patients, the baseline review was conducted before evidence application, and the effectiveness of evidence application at 7 days and 14 days was evaluated.Results:① A total of 19 pieces of literature were included, including 4 guidelines, 1 summary of evidence, 4 expert consensuses, 4 systematic reviews, and 6 original studies (1 quasi-experiment, 5 RCT). After literature quality evaluation, all 19 articles were enrolled. Finally, 31 pieces of best evidence were extracted from eight aspects, including assessment and diagnosis, multidisciplinary cooperation, indication, preparation before intervention, intervention program, safety monitoring, post-intervention evaluation, and special task. ② Finally, a total of 30 patients were enrolled in the intervention group, of which 17 completed 14 days of rehabilitation exercise, and 13 completed 7 days of rehabilitation exercise. Twenty-seven patients were enrolled in the control group, of which 17 completed 14 days of monitoring, and 10 completed 7 days of monitoring. Clinical evidence application results showed that the patients in the intervention group did not experience adverse events such as increased heart rate, extubation, or physical discomfort. The skeletal muscle mass index (SMI) in both groups was gradually decreased with the prolongation of intervention duration, but the 7-day SMI in the intervention group was significantly higher than that in the control group (kg/m 2: 8.61±2.66 vs. 6.65±1.50, P < 0.01). Conclusion:By summarizing the best evidence and evidence-based practice of exercise intervention for elderly patients with sarcopenia in ICU, this study confirmed the feasibility due to safe and effective of implementing early exercise intervention for elderly sarcopenia patients in ICU.

Objective:To investigate and analysis of the occurrence and influencing factors of sarcopenia in elderly critically ill patients in the intensive care unit (ICU).Methods:A prospective cohort study was conducted. Elderly patients (aged ≥ 60 years) admitted to the ICU of Tianjin Medical University General Hospital from November 2023 to June 2024 were enrolled. Clinical records were collected, and conduct muscle mass and strength measurements, as well as upper arm circumference and calf circumference were measured. Appendicular skeletal muscle index (ASMI) of less than 7.0 kg/m 2 for males and less than 5.7 kg/m 2 for females was defined as reduced muscle mass, grip strength of less than 28 kg for males and less than 18 kg for females was defined as decreased muscle strength, patients meeting both low muscle mass and low muscle strength criteria were diagnosed with sarcopenia. According to the diagnostic criteria for sarcopenia, patients were divided into sarcopenia group and non-sarcopenia group. Multivariate Logistic regression analysis was applied to identify risk factors for sarcopenia in the elderly and to develop a predictive model for the occurrence of sarcopenia. The predictive value of various risk factors for sarcopenia in elderly critically ill patients were evaluated by receiver operator characteristic curve (ROC curve). The Kaplan-Meier curve for the length of ICU stay of two groups patients were drawn. Results:Finally, 540 elderly critically ill patients were included, including 43 patients with sarcopenia, and the incidence of sarcopenia was 8.0%. Univariate analysis showed that there were significantly differences in body mass index (BMI), number of hospitalizations in the past year, the length of ICU stay, ventilation mode, duration of mechanical ventilation, pre-admission exercise habits, nutritional support methods, upper arm circumference, calf circumference, and albumin infusion between the sarcopenia group and the non-sarcopenia group. Multivariate Logistic regression analysis showed that BMI [odds ratio ( OR) = 0.79, 95% confidence interval (95% CI) was 0.67-0.93, P = 0.004], calf circumference ( OR = 0.64, 95% CI was 0.54-0.76, P < 0.001), and duration of mechanical ventilation ( OR = 1.06, 95% CI was 1.01-1.12, P = 0.034) were associated with an increased risk of sarcopenia in elderly critically ill patients. The ROC curve results showed that the area under the curve (AUC) and 95% CI of BMI, calf circumference, and duration of mechanical ventilation for predicting sarcopenia in elderly critically ill patients were 0.828 (0.767-0.888), 0.889 (0.844-0.933), and 0.397 (0.299-0.496), respectively, with cut-off values of 22.95 kg/m 2, 28.25 cm, and 50.50 days, respectively. The Kaplan-Meier curve showed that the cumulative survival rate of patients with sarcopenia was significantly lower than that of the non-sarcopenia group (Log-Rank test: χ 2 = 5.619, P = 0.018). Conclusion:Lower BMI, smaller calf circumference, and longer duration of mechanical ventilation are associated with an increased risk of sarcopenia in critically ill elderly patients.
