Objective:To investigate the combined therapeutic role of the AKT inhibitor MK2206 and Ruxolitinib in treating Myeloproliferative Neoplasms (MPN) driven by a calreticulin (CALR) gene mutation.Methods:① Murine bone marrow c-kit + cells were isolated by sacrificing mice and harvesting bone marrow from the femur, tibia, and ilium for subsequent c-kit + cell sorting. ② A CALR transplantation mouse model was established. GFP-tagged retroviral vectors containing either the CALR gene mutation or the migR1 control were constructed, packaged in Platinum-E cells, and used to transduce murine bone marrow c-kit + cells. These transduced cells were then transplanted into lethally irradiated female recipient mice via tail vein injection. ③ Following successful engraftment, the mice were randomly assigned to four treatment groups for intragastric administration. Complete blood counts were monitored periodically, and the spleen size and weight of transplanted mice were measured. ④ Flow cytometry was used to quantify the proportions of GFP + tumor cells, megakaryocytic lineage cells, and hematopoietic stem cells in both splenic and bone marrow tissues. Histopathological examination was performed to evaluate the degree of tumor cell infiltration in these organs. Results:① Following gavage treatment, peripheral blood platelet (PLT) and white blood cell counts were significantly lower in the combined AKT inhibitor MK2206 and Ruxolitinib group compared to the MK2206, Ruxolitinib, and control groups ( P<0.05). ② In comparison with the MK2206 and Ruxolitinib monotherapy groups, the combination therapy group exhibited a significant reduction in spleen weight and a marked improvement in splenomegaly at 30 weeks post-transplantation ( P<0.05). ③ After four weeks of continuous treatment, combined administration resulted in a significant decrease in the proportion of megakaryocytic lineage cells and GFP + tumor cells in the bone marrow and spleen ( P<0.05). Additionally, the proportion of hematopoietic stem cells in the bone marrow was also significantly reduced ( P<0.05). ④ Histopathological analysis (H&E staining) of bone marrow and spleen tissues confirmed that the combined regimen decreased both tumor cell infiltration and the proportion of abnormal megakaryocytes in these organs. Conclusion:The combination of AKT inhibitor MK2206 and Ruxolitinib is effective at significantly ameliorating disease symptoms and reducing tumor infiltration in vivo in mice with a myeloproliferative tumor transplantation driven by a CALR gene mutation.

Cholangiocarcinoma (CCA) is a fatal malignancy with steadily increasing incidence and poor prognosis. Since most CCA cases are diagnosed at an advanced stage, systemic therapies, including chemotherapy, radiotherapy, targeted therapy, and immunotherapy, play a crucial role in the management of unresectable CCA. The recent advances in targeted therapies and immunotherapies brought more options in the clinical management of unresectable CCA. This review depicts the advances of targeted therapies and immunotherapies for unresectable CCA, summarizes crucial clinical trials, and describes the efficacy and safety of different drugs, which may help further develop precision and individualization in the clinical treatment of unresectable CCA.

Sodium-glucose transporter 2 inhibitors (SGLT2i) are currently widely used as a class of hypoglycemic drugs. Due to their unique hypoglycemic mechanism and significant cardio-renal protective effect, SGLT2i have become one of the core drugs in the treatment of type 2 diabetes mellitus. However, in recent years, it has been found that SGLT2i can lead to increased serum creatinine and urea nitrogen in some patients, and the risk of kidney injury has gradually attracted clinical attention. How to effectively prevent and supervise the potential renal injury risk while giving full play to its therapeutic advantages has become an important topic in current clinical practice and drug safety management. Multi-dimensional prevention and supervision strategies should be adopted in clinical practice such as identifying high-risk populations based on the latest evidence, strictly screening patients, dynamically monitoring renal function, optimizing combination medication regimens, and achieving risk warning using biomarkers and artificial intelligence tools.

Objective: This study aimed to determine the predictive performance of non-contrast CT (NCCT) signs for hemorrhagic growth after intracerebral hemorrhage (ICH) when stratified by onset-to-imaging time (OIT). Materials and Methods: 1488 supratentorial ICH within 6 h of onset were consecutively recruited from six centers between January 2018 and August 2022. NCCT signs were classified according to density (hypodensities, swirl sign, black hole sign, blend sign, fluid level, and heterogeneous density) and shape (island sign, satellite sign, and irregular shape) features. Multivariable logistic regression was used to evaluate the association between NCCT signs and three types of hemorrhagic growth: hematoma expansion (HE), intraventricular hemorrhage growth (IVHG), and revised HE (RHE). The performance of the NCCT signs was evaluated using the positive predictive value (PPV) stratified by OIT. Results: Multivariable analysis showed that hypodensities were an independent predictor of HE (adjusted odds ratio [95% confidence interval] of 7.99 [4.87–13.40]), IVHG (3.64 [2.15–6.24]), and RHE (7.90 [4.93–12.90]). Similarly, OIT (for a 1-h increase) was an independent inverse predictor of HE (0.59 [0.52–0.66]), IVHG (0.72 [0.64–0.81]), and RHE (0.61 [0.54– 0.67]). Blend and island signs were independently associated with HE and RHE (10.60 [7.36–15.30] and 10.10 [7.10–14.60], respectively, for the blend sign and 2.75 [1.64–4.67] and 2.62 [1.60–4.30], respectively, for the island sign). Hypodensities demonstrated low PPVs of 0.41 (110/269) or lower for IVHG when stratified by OIT. When OIT was ≤ 2 h, the PPVs of hypodensities, blend sign, and island sign for RHE were 0.80 (215/269), 0.90 (142/157), and 0.83 (103/124), respectively. Conclusion Hypodensities, blend sign, and island sign were the best NCCT predictors of RHE when OIT was ≤ 2 h. NCCT signs may assist in earlier recognition of the risk of hemorrhagic growth and guide early intervention to prevent neurological deterioration resulting from hemorrhagic growth.

OBJECTIVE To explore the effects of ADRB1 Arg389Gly polymorphisms on the efficacy of bisoprolol， thus providing some information for individualized drug therapy. METHODS A systematic search was conducted in PubMed， Embase， Cochrane Library， CBM， CNKI， and Wanfang Data to retrieve and find out all relevant literature about bisoprolol and ADRB1 Arg389Gly polymorphism from the inception to May 2023. The retrieved literature was screened and selected according to the inclusive and exclusive criteria， thereafter quality assessment was conducted. RevMan 5.4 software was utilized to perform the meta- analysis for the outcome index. RESULTS Overall 7 literature with 1 339 cases were included. Among them， 4 studies provided the changes in systolic blood pressure （SBP）， diastolic blood pressure （DBP） （ΔSBP and ΔDBP）； 4 involving the change （ΔLVEF） of left ventricular ejection fraction （LVEF）. Results of the study showed that there was no statistical significance in the improvement of blood pressure between wild-type group （AA） and mutation group （AG+GG） of ADRB1 Arg389Gly treated with bisoprolol {ΔSBP [SMD＝0.17，95%CI （－0.97，1.31）， P＝0.77]， ΔDBP [SMD＝－0.01，95%CI （－0.65，0.62）， P＝0.97]}； there was no statistical significance in the improvement of ΔLVEF [SMD＝－0.61， 95%CI （－2.74，1.53）， P＝0.58] between 2 groups. CONCLUSIONS ADRB1 Arg389Gly gene polymorphism has no significant influence on the improvement of SBP， DBP， and LVEF in cardiovascular patients who use bisoprolol.
