Effect of Wenjingtang on Levels of Serum Platelet Activating Factor and β-endorphins in Primary Dysmenorrhea Patients with Cold Stagnation and Blood Stasis Syndrome / 中国实验方剂学杂志

Objective::To explore the effect of Wenjingtang on the levels of serum platelet activating factor (PAF) and β-endorphins in primary dysmenorrhea patients with cold stagnation and blood stasis syndrome. Method::The 120 cases of dysmenorrhea treated at Second Affiliated Hospital, Heilongjiang University of Chinese Medicine from March 2016 to December 2017 were selected as the observation subjects, and divided into control group and observation group according to the random number table method, with 60 cases in each group. The control group was treated with ibuprofen capsules, while the observation group was treated with Wenjingtang and ibuprofen capsules. Dysmenorrhea symptom scores, clinical efficacy, recurrence condition and serum levels of platelet activating factor and β-endorphins were compared before and after treatment. Result::After treatment, the dysmenorrhea symptom scores decreased significantly in both groups, and the scores of patients in observation group were lower than those in control group (P<0.05). After treatment, the total efficiency in observation group was 95%, which was significantly higher than 83.33% in control group (P<0.05). The level of serum PAF decreased significantly in two groups, and the serum PAF in observation group was significantly decreased compared with control group (P<0.05). The level of serum beta-endorphins in observation group was significantly higher than that of control group (P<0.05). After half a year, the recurrence rate of the observation group was 5%, which was significantly lower than 30% of control group (χ2=12.987, P<0.01). Conclusion::Wenjingtang contributes to the reduction of dysmenorrhea symptoms scores in primary dysmenorrhea patients with cold stagnation and blood stasis syndrome, and can improve the clinical efficacy, reduce the serum PAF level and increase the concentration of β-endorphins, reduce the recurrence rate, improve the quality of life of patients, and it is worth promoting.

Expression of Elf-1 and survivin in non-small cell lung cancer and their relationship to intratumoral microvessel density / 癌症

<p><b>BACKGROUND AND OBJECTIVE</b>The expression of transcription factor Elf-1 and inhibitor of apoptosis survivin in non-small cell lung cancer (NSCLC) is correlated with the angiogenic factor vascular endothelial growth factor (VEGF), and are both factors affecting the cell cycle. This study investigated the expression of Elf-1, survivin, and intratumoral microvessel density (iMVD) assessed by monoclonal antibody CD105 in NSCLC, and explored their correlations with clinicopathologic features and angiogenesis of NSCLC.</p><p><b>METHODS</b>PowerVision(TM)-9000 immunohistochemistry was used to evaluate the expression of Elf-1, survivin, and CD105 in tissue microarrays containing 60 specimens of NSCLC and 9 specimens of normal tissue. Western blot analysis was used to evaluate the protein levels of Elf-1 and survivin in 17 specimens of NSCLC and 5 specimens of normal tissue.</p><p><b>RESULTS</b>Elf-1 and survivin were detected in 1 of the 9 normal tissues. The positive rates of Elf-1 and survivin in NSCLC were 70.0% and 65.0%, respectively. The expression levels of both Elf-1 and survivin were significantly related to tumor differentiation, lymphatic metastasis, clinical stage, and postoperative survival time (P < 0.05). Overexpression of both were related to poor prognosis: the survival rates were significantly lower in patients with positive expression than in those with negative expression (P < 0.01). Elf-1 expression was positively correlated with survivin expression (r = 0.769, P < 0.01). Elf-1 and survivin expressions were positively correlated with iMVD (r = 0.446, P < 0.01; r = 0.435, P < 0.01).</p><p><b>CONCLUSIONS</b>The expression of Elf-1 and survivin in NSCLC is related to differentiation, lymphatic metastasis, clinical stage, and prognosis, and both are positively correlated with iMVD. Detection their combined expression can help to predict the malignant behavior of NSCLC. Blocking the activity of Elf-1 and survivin may be a new way to inhibit angiogenesis in NSCLC.</p>

Comparative study on the efficacy of Yiweining and Gestrinone for post-operational treatment of stage III endometriosis / 中国结合医学杂志

<p><b>OBJECTIVE</b>To observe the clinical efficacy and safety of Yiweining (YWN) and gestrinone (GT) in treating post-operational patients of stage III endometriosis (EM-III).</p><p><b>METHODS</b>Fifty-two patients of EM-III after operation were randomly assigned into three groups, the YWN group (20 patients) was treated through oral intake of YWN 200 ml, twice a day; the GT group (19 patients) treated with gestrinone 2.5 mg, twice every week, with the medication starting from the 7th post-operational day and lasting for 6 months. The control group (13 patients) was untreated. Six months was one therapeutic course, and follow-up study was carried out in the 6 - 30 months after the end of the medication.</p><p><b>RESULTS</b>The recurrence rate in the YWN group and the GT group were 5.0% and 5.3% respectively, showing insignificant difference between the two groups, but they were lower than that in the control group (30.7%, P < 0.05). Besides, the adverse reaction rate in the YWN group was lower than that in the GT group (10.0% vs 31.6%, P < 0.05).</p><p><b>CONCLUSION</b>Application of YWN to prevent the post-operational recurrence of endometriosis is effective and safe, and its efficacy is similar to that of GT.</p>
