[Effect of self-made Qingyuan Shenghua decoction on coagulation dysfunction in patients with sepsis].

OBJECTIVE: To observe the effects of self-made Qingyuan Shenghua decoction on coagulation dysfunction in patients with sepsis, and to explore its possible mechanism. METHODS: Eighty patients with sepsis and coagulation dysfunction admitted to the department of critical care medicine of Chengdu First People's Hospital from March 2018 to April 2020 were enrolled. The patients were divided into control group and observation group according to random number table method, with 40 cases in each group. Patients in both groups received basic treatment for sepsis. On this basis, the observation group was administrated with self-made Qingyuan Shenghua decoction, one dose a day, 100 mL in the morning and 100 mL in the evening; the control group was given the same amount of normal saline. Both groups were treated for 7 days. Prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR), fibrinogen (Fib), D-dimer, platelet count (PLT), white blood cell count (WBC), C-reactive protein (CRP), and procalcitonin (PCT) were measured before and after treatment, and acute physiology and chronic health evaluation II (APACHE II) and sequential organ failure assessment (SOFA) were calculated. The length of intensive care unit (ICU) stay, the incidence of multiple organ dysfunction syndrome (MODS) and 28-day mortality was recorded. RESULTS: The indexes of coagulation function and inflammation in the two groups were significantly improved after treatment, the improvement of various indexes in the observation group were better than those in the control group [PT (s): 16.01±1.08 vs. 19.21±1.38, APTT (s): 55.33±15.29 vs. 79.41±12.69, INR: 1.30±0.21 vs. 1.65±0.22, Fib (g/L): 2.87±0.89 vs. 5.44±1.13, D-dimer (mg/L): 2.56±1.67 vs. 6.41±2.42, PLT (×109/L): 125.79±18.51 vs. 95.46±18.50, WBC (×109/L): 7.50±0.78 vs. 12.75±4.09, CRP (mg/L): 21.27±9.32 vs. 65.44±13.40, PCT (µg/L): 1.15±0.58 vs. 6.31±1.29], and the differences were statistically significant (all P < 0.05). After treatment, APACHE II and SOFA scores in the two groups decreased significantly compared with those before treatment, and the decrease in the observation group were more obvious than those in the control group (APACHE II score: 10.29±1.86 vs. 15.35±2.06, SOFA score: 5.51±1.08 vs. 7.65±1.58, both P < 0.05). The length of ICU stay was shortened in the observation group than that in the control group (days: 12.22±9.48 vs. 20.22±15.35, P < 0.05). The incidence of MODS [35.0% (14/40) vs. 47.5% (19/40)] and the 28-day mortality [45.0% (18/40) vs. 47.5% (19/40)] was lower than that of the control group, but there was no statistical difference (both P > 0.05). CONCLUSIONS: Self-made Qingyuan Shenghua decoction can effectively improve the prognosis of patients with coagulation dysfunction and sepsis, and its mechanism may be related to inhibition of inflammatory reaction and improvement of coagulation function.

Tetramethylpyrazine reduces prostate cancer malignancy through inactivation of the DPP10­AS1/CBP/FOXM1 signaling pathway.

Tetramethylpyrazine (TMP), a Chinese herbal medicine, has been reported to possess anticancer effects. Emerging evidence suggests that various long noncoding RNAs (lncRNAs) serve important roles in cancer initiation and progression. In the present study, the tumor­suppressive effects of TMP in human PCa cells was examined and the underlying mechanisms of its actions were determined. The data showed that TMP treatment reduced cell viability and increased apoptosis in a dose­dependent manner. Reverse transcription­quantitative PCR showed TMP treatment increased the expression of lncRNA DPP10­AS1 in PCa cells. Furthermore, DPP10­AS1 was also upregulated in TMP­resistant PCa cells. Knockdown of DPP10­AS1 reversed TMP resistance, whereas increased expression of DPP10­AS1 abrogated the TMP­mediated cytotoxicity in PCa cells. In addition, forkhead box M1 (FOXM1) was verified as the functional target of DPP10­AS1, and knockdown of FOXM1 reversed the TMP/DPP10­AS1­induced cell cytotoxicity. Mechanistically, DPP10­AS1 was associated with CREB binding protein, thereby induced H3K27ac enrichment at the promoter region of the FOXM1 gene. In conclusion, the present study showed that TMP may be a promising treatment agent for PCa and lncRNA DPP10­AS1 may be a promising therapeutic target for TMP treatment.
