Short-term efficacy of Shenmai injection combined with FOLFOX chemotherapy in the treatment of advanced gastric cancer and its effects on immune function and tumor markers / 中国基层医药

Objective:To investigate the short-term efficacy of Shenmai injection combined with FOLFOX chemotherapy in the treatment of advanced gastric cancer and its effects on immune function and tumor markers. Methods:Eighty-two patients with advanced gastric cancer who received treatment in Shengzhou Hospital of Traditional Chinese Medicine, China between June 2018 and June 2020 were included in this study. They were randomly assigned to receive either FOLFOX chemotherapy (control group, n = 41) or Shenmai injection combined with FOLFOX chemotherapy (observation group, n = 41). All patients received three 21-day courses of treatment. Short-term efficacy of chemotherapy and improvement in quality of life were compared between the two groups. Immune function, expression of tumor markers (carcinoembryonic antigen and carbohydrate antigen 724) and adverse reactions were determined before and after three courses of treatment. Results:Total effective rate in the observation group was significantly higher than that in the control group [70.73% (29/41) vs. 46.34% (19/41), χ2 = 5.025, P < 0.05]. The proportion of patients had improved quality of life in the observation group was significantly higher than that in the control group [78.05% (32/41) vs. 56.10% (23/41), χ2 = 4.473, P < 0.05]. After three courses of treatment, the proportion of CD 3+ and CD 4+ cells and the ratio of CD 4+/CD 8+ cells in the observation group were (58.39 ± 3.14)%, (38.79 ± 2.35)% and (1.54 ± 0.17), respectively, which were significantly higher than those in the control group [(48.10 ± 3.01)%, (30.10 ± 1.78)%, (0.92 ± 0.15), t = 15.148, 18.875, 17.511, all P < 0.05]. After three courses of treatment, serum carcinoembryonic antigen and carbohydrate antigen 724 levels in the observation group were (6.98 ± 1.45) μg/L and (7.85 ± 1.76) μg/L, respectively, which were significantly lower than those in the control group [(15.47 ± 3.21) μg/L, (18.97 ± 3.25) μg/L), t = 15.434, 19.265, both P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:Shenmai injection combined with FOLFOX chemotherapy in the treatment of advanced gastric cancer exhibits good short-term efficacy, can improve the immune function, and reduce the levels of carcinoembryonic antigen and carbohydrate antigen 724.

Effect of polydatin on dynamic changes of excitatory amino acids in cerebrospinal fluid of cerebral hemorrhage rats / 中国中药杂志

<p><b>OBJECTIVE</b>To observe the effects of polydatin on dynamic changes of excitatory amino acids in cerebrospinal fluid and water content of brain tissue of cerebral hemorrhage rats. And to discuss the therapeutic action and mechanisms of polydatin on brain hemorrhagic injured rats.</p><p><b>METHOD</b>A quantitative determination method of Asp and Glu was established by microdialysis-HPLC. The cerebral hemorrhage model in rats was induced by local injection of type VII collagenase. The dynamic changes of Asp and Glu in cerebrospinal fluid were observed on 0, 6, 12, 24, 36, 48, 60, 72, 84, 96, 108 h of cerebral hemorrhage rats, and then the water content of brain tissue was detected.</p><p><b>RESULT</b>The content of Asp and Glu increased rapidly within 24 h after cerebral hemorrhage, and to the highest in 24 h, then decreased gradually. Compared with the cerebral hemorrhage model group, the content of Asp and Glu increased slowly in polydatin group, and there were significant differences in 12-72 h and 6-84 h (P < 0.01, P < 0.05), but there was no significant difference after 84 h and 96 h. Compared with sham group, water content of brain tissue significantly higher in model group, while significantly lower (P < 0.01) in polydatin group.</p><p><b>CONCLUSION</b>Polydatin can inhibit increasing content of Asp and Glu in cerebrospinal fluid dynamics, and significantly inhibit cerebral edema of cerebral hemorrhage rats. It shows that the mechanisms of anti-cerebral hemorrhage injury of polydatin may be related to increasing of excitatory amino acids after cerebral hemorrhage.</p>

Dual- direction effect of crenulatin on apoptosis of cerebral microvascular endothelial cells and it's mechanism / 中国病理生理杂志

AIM: To study the effect and the mechanism of crenulatin, an effective constituent of Chinese traditional medicine, on apoptosis of cerebral microvascular endothelial cells. METHODS: The following terminal concentrations of crenulatin were used in the study: 25 mg/L and 100 mg/L. Apoptosis of mouse cerebral microvascular endothelial cells (bEnd. 3 cell line) was evaluated by flow cytometer, immunocytochemical assay (Fas, Bcl - 2) and Western blotting (caspase - 3) after culture for 24 h. RESULTS: Compared with control group, apoptosis of bEnd. 3 cells in 25 mg/L group was significantly inhibited ( P ＜0.05), but apoptosis in the 100 mg/L group was significantly increased (P ＜ 0.05). In apoptosis inhibited group, the Fas immunocytochemical staining was weaker, the positive cells were significantly decreased ( P ＜ 0.05) and caspase - 3 expression was decreased compared with control group; however, the Bcl - 2 staining was stronger and the positive cells were significantly increased ( P ＜ 0.05). On the other hand, in apoptosis increased group ( 100 mg/L group), the changes were just opposite. CONCLUSIONS: The effect of crenulatin on apoptosis of mouse cerebral microvascular endothelial cells possesses a dual - direction change, inhibitive effect in 25 mg/L and stimulative effect in 100 mg/L group, respectively. The mechanism is related to the alterations of Fas/Bcl - 2 expression and caspase - 3 activity.
