Objective To explore the effect of early intervention on patients with severe illness deterioration induced multiple organ dysfunction syndrome(MODS). Methods 184 severe patients were randomly divided into conventional treatment and intervention groups(each,92 cases). Active treatment of primary disease and symptomatic treatment were given to the patients in the control group,and based on the treatment of the above group, low dose heparin was additionally given to the observation group for anticoagulation to change hemorheology. Before and after treatment for 1 week,life signs,blood routine test,blood biochemistry,blood coagulation index,D-dimer, hemorheology,blood gas analysis and acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)score were observed in two groups to judge the overall changes of disease situation. The length of stay in intensive care unit(ICU), the incidence of MODS and mortality after 1 week treatment were compared between the two groups. Results The levels of platelet count(PLT),fibrinogen(Fib),D-dimer,whole blood high shear viscosity,whole blood low shear viscosity,plasma viscosity,white blood cell count(WBC),arterial blood lactate(Lac),alanine aminotransferase (ALT),serum creatinine(SCr),APACHE Ⅱ score in two groups after the treatment were decreased significantly, while oxygenation index(PaO2/FiO2),mean arterial pressure(MAP)were increased significantly,and the observation group improvement was better than that of the control group〔PLT(×109/L):180.74±85.59 vs. 214.33±78.68,Fib (g/L):3.15±0.83 vs. 3.22±1.89,D-dimer(g/L):0.35±0.17 vs. 0.72±0.25,whole blood high shear viscosity (mPa · s):5.54±2.26 vs. 6.73±2.48,whole blood low shear viscosity(mPa · s):8.56±2.12 vs . 11.76±3.45,plasma viscosity(mPa · s):1.35±0.24 vs. 1.82±0.50,WBC(×109/L):10.75±5.53 vs. 14.34±8.66,PaO2/FiO2(mmHg, 1 mmHg=0.133 kPa):288.52±85.34 vs. 216.34±97.72, MAP(mmHg):99.52±20.85 vs. 90.73±21.86, Lac (mmol/L):2.72±1.08 vs. 4.46±2.87, ALT (U/L):89.73±22.45 vs. 125.23±77.48, SCr (μmol/L):110.19±35.26 vs. 140.23±68.96,APACHEⅡscore:13.29±3.74 vs. 18.45±3.52,all P<0.05〕;in the control group,the activated partial thromboplastin time(APTT)after treatment was decreased significantly(s:40.76±9.89 vs. 42.39±12.47),while in the observation group,increased(57.50±7.12 vs. 41.74±13.62). Compared with the control group,the length of stay in ICU was shortered(days:4.1±1.5 vs. 4.6±2.3,P<0.05),the incidence of MODS (22.8% vs. 46.7%,P<0.05)and mortality(6.5% vs. 14.1%,P<0.05)were reduced significantly in observation group. No serious complications occurred in two groups. Conclusion Anti-coagulant used for early intervention can control the disease progress and prevent the patients with severe disease from further deterioration,thus it may reduce the incidence of secondary MODS and mortality,shorten the duration of hospitalization in ICU and save the cost.

Background and Objectives:
Glioblastoma (GBM) is an aggressive primary brain tumor characterized by its hetero-geneity and high recurrence and lethality rates. Glioblastoma stem cells (GSCs) play a crucial role in therapy resistance and tumor recurrence. Therefore, targeting GSCs is a key objective in developing effective treatments for GBM. The role of Parathyroid hormone-related peptide (PTHrP) in GBM and its impact on GSCs remains unclear. This study aimed to investigate the effect of PTHrP on GSCs and its potential as a therapeutic target for GBM.
Methods:
and Results: Using the Cancer Genome Atlas (TCGA) database, we found higher expression of PTHrP in GBM, which correlated inversely with survival. GSCs were established from three human GBM samples obtained after surgical resection. Exposure to recombinant human PTHrP protein (rPTHrP) at different concentrations significantly enhanced GSCs viability. Knockdown of PTHrP using target-specific siRNA (siPTHrP) inhibited tumorsphere formation and reduced the number of BrdU-positive cells. In an orthotopic xenograft mouse model, suppression of PTHrP expression led to significant inhibition of tumor growth. The addition of rPTHrP in the growth medium counteracted the antiproliferative effect of siPTHrP. Further investigation revealed that PTHrP increased cAMP concentration and activated the PKA signaling pathway. Treatment with forskolin, an adenylyl cyclase activator, nullified the antiproliferative effect of siPTHrP.
Conclusions
Our findings demonstrate that PTHrP promotes the proliferation of patient-derived GSCs by activating the cAMP/PKA signaling pathway. These results uncover a novel role for PTHrP and suggest its potential as a therapeutic target for GBM treatment.

Objective To observe the clinical effect of the Bushen-Qiangjin capsule and calcium D in the treatment of aromatase inhibitors-associated bone loss (AIBL) in breast cancer patients. Methods A total of 65 patients were randomized into a treatment group and a control group, 32 in the control group taking calcium D, and 33 in the treatment group taking calcium D and Bushen-Qiangjin capsule. After a 3-month treatment, the bone mineral density T (BMD), bone-specific alkaline phosphatase (BALP), bone gla protein (BGP) and tartrate resistant acid phosphatase (TrACP) of two groups were evaluated. Results The BMD increased significantly after treatment in both groups (P<0.05), and the therapeutic efficacy of the treatment group was better than of the control group (P<0.05). After treatment, the level of BALP (308.76 ± 10.99 U/L vs. 280.00 ± 7.44 U/L, t=8.170) and the BGP (42.21 ± 3.04 ng/ml vs. 34.38 ± 2.06 ng/ml, t=6.818) of the treatment group were significantly higher than those of the control group (P<0.01). The level of TrACP decreased significantly after treatment in both groups (P<0.05), and the TrACP (60.12 ± 4.58 U/L vs. 67.25±4.06 U/L, t=1.653) of treatment group was significantly lower than that of the control group (P<0.05). Conclusions The Bushen-Qiangjin capsule can produce a content efficacy in treating AIBL in breast cancer patients, improving the BMD and bone metabolism.

This article explores the interaction between aspirin and safflower yellow injection from the perspective of pharmacokinetics, combined with pharmacological indicators such as anticoagulation. Quantitative HPLC analysis was performed for the detection of salicylic acid in plasma samples, and the pharmacokinetic effects of aspirin in combination with safflower yellow injection on aspirin’s hydrolyzed product salicylic acid was evaluated. Thromboxane B2 (TXB2) and 6-keto prostaglandin F1 in plasma were determined using enzyme-linked immunosorbent assay and fully automated biochemical analyzer α (6-keto-PGF1) α), and the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), and serum creatinine (Scr) were tested to evaluate the anticoagulant effect and safety indicators after long-term combined use of the two drugs, including liver and kidney function and cardiac pathological examination. The results showed that, compared with the aspirin group, there was no significant difference (P>0.05) in the plasma pharmacokinetic parameters of rats with combined use of safflower yellow injection. In addition, the plasma TXB2 in the combination group was significantly reduced compared to the aspirin group (P<0.01), yet with no significant difference for 6-keto-PGF1 α (P>0.05). There was no statistically significant difference in the levels of serum BUN, Scr, AST, and ALT between the two groups before and after treatment (P>0.05). These results suggest that the combination of aspirin and safflower yellow injection does not cause significant change in the blood concentration of salicylic acid. It does not affect the antiplatelet effect of aspirin.
