Uric acid as a mediator in the correlation between white blood cells and preeclampsia severity: a retrospective cohort study.

This study aimed to analyze the independent risk factors for predicting preeclampsia severity and explore its underlying mechanism. Clinical data of patients with preeclampsia were collected from the Medical Information Mart for Intensive Care (MIMIC)-IV database. Univariate and multivariate analyses were employed to assess the significant factors associated with preeclampsia severity. Additionally, we performed multivariate logistic regression analysis and mediation analysis to investigate the potential regulatory path. Based on inclusion and exclusion criteria, 731 participants were enrolled: severe preeclampsia (n = 381) and mild to moderate preeclampsia (n = 350). Age, white blood cells (WBC), platelet, creatinine, albumin, uric acid, aspartate aminotransferase, alanine aminotransferase, international normalized ratio, and prothrombin time were significantly related to preeclampsia severity. Besides, hospital length of stay was significantly higher in the severe group. Notably, age and uric acid were independent predictors for preeclampsia severity. Further, WBC and creatinine were significantly associated with uric acid. Finally, the mediation analysis showed that uric acid was a mediator of the relationship between WBC and preeclampsia severity. In conclusion, WBC might affect preeclampsia severity and progression via the mediation of uric acid. This study might provide novel insight into preventing preeclampsia development.

[Clinical curative effects of preoperative neoadjuvant chemotherapy on cervical cancer: analysis of 62 patients].

OBJECTIVE: To explore the clinical curative effects of preoperative neoadjuvant chemotherapy (NACT) on locally advanced cervical cancer. METHODS: A total of 62 patients of stage Ib2-IIb cervical cancer received neoadjuvant chemotherapy of paclitaxel plus cisplatin for 2 - 3 courses. The clinical curative effects were evaluated according to the changes of lesion size, intraoperative conditions and postoperative pathological reactions. RESULTS: The overall response rate was 90.32% (56/62) and the complete response rate 30.65% (19/62). The tumor volumes decreased after NACT. The differences were significant (P < 0.05). After NACT, 56 patients undergoing radical hysterectomy recovered smoothly. The surgical resection rate was 90.32%. Chemotherapeutic reactions of cancerous tissue and a large number of infiltrated lymphocytes were seen in 50 cases. Lymph nodes were positive in 3 cases. There were parametrial invasion (n = 2) and vascular tumor emboli (n = 2). CONCLUSION: Preoperative neoadjuvant chemotherapy is efficacious in cervical cancer. The parametrium becomes softer and the tumor staging decreases.

[Experimental study on antivirus activity of traditional Chinese medicine].

OBJECTIVE: To investigate the difference of anticytomegaloviral activity of three kinds of traditional Chinese medicines which are the injections of Jinye Baidu, Radix Isatidis and Indigowoa in vitro. METHOD: The inhibitory activity of three traditional Chinese medicines against human cytomeglovirus (HCMV AD169) infected human embryo lung fibroblasts (HELF) was observed by cytopathic effect method (CPE) and MTT method in vitro. According their value of A, anticytomegaloviral activity has evaluated. RESULT: Experimental study in vitro showed that the 50% toxicity dose (TD50) of Jinye Detoxifying, Radix Isatidis root and Indigowoa were 20, 10.23, 20.23 g x L(-1) respectively; the 50% inhibitory concertration (IC50) were 5.65, 3, 5.71 g x L(-1) respectively; the therapeutic index (TI) were 3.54, 3.41 and 3.54 respectively. It suggested that three traditional Chinese medicines had anticytomeglovirus activity and their effect increased with their concentration. CONCLUSION: Three traditional Chinese medicines of the parenteral solution of Jinye Detoxifying, Radix Isatidis root and Indigowoa have antiviral activity when they are diluted in 1:200. They are safe and valuable drug for inhibiting cytomeglovirus infection.
