Retrospective analysis of 35 burn patients in different stages of pregnancy / 中华烧伤杂志

Objective: To summarize the clinical outcomes of burn patients in different stages of pregnancy and explore a rational therapeutic scheme for burns during pregnancy. Methods: A retrospective observational study was conducted. From June 2010 to June 2020, 21 patients who met the inclusion criteria were admitted to the Department of Burns of Wuhan Third Hospital and 14 patients who met the inclusion criteria were admitted to the Department of Burns of the First Affiliated Hospital of Nanchang University. Based on the pregnancy period when patients suffered burns, the 35 patients were divided into early pregnancy group with 18 patients (aged (26±4) years, with 8 (4, 11) weeks of gestation), middle pregnancy group with 10 patients (aged (26±3) years, with 21 (14, 27) weeks of gestation), and late pregnancy group with 7 patients (aged (30±5) years, with 32 (29, 35) weeks of gestation). All the patients received treatment including fluid resuscitation, anti-infection, wound treatment, and multidisciplinary comprehensive managements. The burn-related complications during the treatment, maternal outcomes, fetal outcomes, fetal delivery mode, gestational weeks at delivery, and newborn weight of patients in the 3 groups were recorded. Data were statistically analyzed with one-way analysis of variance, Kruskal-Wallis test, and Fisher's exact probability test. Results: During the treatment, there were 4, 4, and 2 patients who suffered wound infections and 1, 3, and 2 patients who developed shock symptoms, respectively, in early pregnancy group, middle pregnancy group, and late pregnancy group. There were no statistically significant differences in them among the 3 groups (P>0.05). One patient in late pregnancy group developed into multiple organ dysfunction syndrome after debridement. At last, all the pregnant women survived, and no statistically significant difference existed among the 3 groups (P>0.05). In early pregnancy group, middle pregnancy group, and late pregnancy group, the survived fetus cases were 9, 8, and 6, respectively, and the differences between them were not statistically significant (P>0.05). Variables including stillbirth and full-term birth were close in patients in the 3 groups (P>0.05), while the preterm birth and miscarriage in patients in the 3 groups were statistically different (P<0.05 or P<0.01), with the early pregnancy group having the most miscarriage cases and the fewest preterm birth cases. There were no statistically significant differences in fetal delivery mode, gestational weeks at delivery, and newborn weight among the patients with survived fetus in 3 groups (P>0.05). Conclusions: For patients suffering burns during early, middle, and late pregnancy, superior rates of maternal and fetal survival can be achieved after timely and adequate treatments including fluid resuscitation, anti-infection, wound treatment, and multidisciplinary comprehensive managements.

Expressions of bFGF and PTEN in cervical carcinoma and their clinical significance / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the expressions of bFGF and PTEN in cervical carcinoma and their clinical significance.</p><p><b>METHODS</b>Tissue microarray technique and immunohistochemistry SP method were used to detect the expressions of bFGF and PTEN in 143 cases of invasive carcinoma of cervix (ICC) and 20 cases of normal cervical epithelium remote from tumor (NCE). The relationship between the expressions of bFGF and PTEN in ICC and some factors relating to clinical pathology of cervical carcinoma such as histopathological grading, lymph node metastasis, stroma involvement and FIGO staging were analyzed.</p><p><b>RESULTS</b>The rate of the positive expression of bFGF in ICC was significantly higher than that in NCE 88.8% (127/143) vs. 25.0% (5/20, P = 0.000). The rate of positive expression of PTEN in ICC was significantly lower than that in NCE 67.1% (96/143) vs. 100.0% (20/20, P = 0.000). The expression of bFGF was positively correlated with lymph node metastasis and histopathological grading (r = 0.239, P = 0.004 and r = 0.369, P = 0.000, respectively). The expression of PTEN was negatively correlated with FIGO staging, histopathological grading and lymph node metastasis (r = -0.189, P = 0.024; r = -0.211, P = 0.011; r = -0.321, P = 0.000, respectively). The expression of bFGF was negatively correlated with the expression of PTEN in ICC (r = -0.261, P = 0.002).</p><p><b>CONCLUSION</b>The overexpression of bFGF and underexpression of PTEN are closely related to the invasion and growth of cervical carcinoma. Detection of the expression of both bFGF and PTEN may be of value in further understanding the biological behavior and predicting the prognosis of cervical carcinoma.</p>
