Objective To investigate the expression of interleukin-37 (IL-37) in placenta tissue and its relationship with the pathogenesis of severe preeclampsia. Methods All the patients were recruited in Qilu Hospital of Shangdong University from November 2012 to November 2013. Among them, thirty patients with severe preeclampsia were assigned to the preeclampsia group, and thirty-one healthy pregnant women were assigned to the control group. Immunohistochemistry of SP was used to detect the IL-37 protein expression in placenta tissue of the two groups. The expression level of IL-37 in placenta tissue of the two groups was detected by western blot. Besides, reverse transcription(RT)-PCR was used to detect the expression of IL-37 mRNA. The correlation between the expression of IL-37 mRNA and the delivery gestational age, body mass index(BMI)was analyzed. Results (1) IL-37 were detected in the placenta of both the preeclampsia group and the control group, and the expression site mainly located in the syncytiotrophoblast, with a small amount in cytotrophoblast.(2)The expression levels of IL-37 protein in the preeclampsia group and the control group were 0.59 ± 0.39 and 0.88 ± 0.22, respectively. The IL-37 mRNA levels in the preeclampsia group and the control group were 0.55 ± 0.17 and 1.11 ± 0.21, respectively. Both decreased significantly when compared to the control group (P<0.05). (3) Significant correlation between the expression of IL-37 mRNA and the delivery gestational weeks(r=0.209, P>0.05) was seen neither in the preeclampsia group nor in the control group(r=-0.053, P>0.05). In the severe preeclampsia group, the pregnant women′s BMI had no significant correlation with IL-37 mRNA expression of placenta tissue(r=0.102, P>0.05), neither did the control group(r=-0.115, P>0.05). Conclusion IL-37 expression is significantly lower in severe preeclampsia placenta tissue than that in the normal pregnant women, which may play a protective role in the course of severe preeclampsia.

Objective To investigate the expression of growth arrest-specific protein 6 (Gas6) in the placenta and decidua tissues and its relationship with the pathogenesis of preeclampsia. Methods All the patients were recruited in Qilu Hospital of Shangdong University from October 2013 to June 2014. Among them, thirty-two women with early-onset severe preeclampsia who received cesarean section were assigned to the preeclampsia group, and thirty healthy pregnant women who received cesarean section were defined as the control group. Blood glucose, blood lipids, platelet count, D-dimer levels and other clinical indicators of the two groups were detected. Immunohistochemistry of SP was conducted to identify the localization of Gas6 protein in the placenta and decidua tissues. And reverse transcription (RT)-PCR was performed for quantitative analysis of Gas6 RNA expression in placentas. The correlations between placental Gas6 mRNA levels with clinical indicators were analyzed. Results (1) The gestational age at delivery, blood pressure, serum albumin, platelet count and birth weight of fetuses showed statistically significant differences between the two groups(P<0.05). (2) The Gas6 protein expressed in the cytoplasm and nucleus of the syncytiotrophoblasts and decidual cells in the placenta and decidual tissues of the two groups. (3) The Gas6 mRNA expression elevated significantly in the placenta of preeclampsia group (0.60 ± 0.38) when compared to that of the control group (0.34±0.22;P<0.05). (4) The expression of Gas6 mRNA was positively related with body mass index, diastolic blood pressure, systolic blood pressure, free fatty acids and creatinine (P<0.05), while it was negatively associated with serum albumin(P<0.05). Conclusion The high expression of Gas6 in the placenta and decidua tissues may be related to the pathogenesis of severe preeclampsia.

Objective:To investigate the clinic-cytology and histopathology of non-Hodgkin lymphoma (NHL) in breasts. Mothods:Twelve cases of NHL of the breast were studied by fine-needle aspiration biopsy (FNAC), histopathology and immunohistochemistry, and whose clinical data were analysed at the same time. Results:In 12 cases of NHL, 3 cases were T-cell NHL and 9 cases were B-cell NHL. Cytologically, the T-cell NHL cells were mostly arranging in diffuse patterns. The tumor cells were oval and pleomorphism. Some of them had distorted nucleus and thin nuclear envelope.The nucleus showed irregular course chromatin and visible nueleoic. Histopathologically, some of the tumor cells distributed around the blood vessels, and there was an obvious phenomenon of “blood-vessel-closing”. B-cell lymphoma cells were arranginy in diffuse pattern, and showed round and ellipse in shape with a clot and course granular chromatin and visible nueleoic and karyoknesis. Lymphoepithelia lesions were seen. Immunohistochemistry showed that CD3, CD43, and CD 45RO in T-cells NHL were positive.CD20, CD74 and CD79a in B-cells NHL were negative. CK, EMA, ER and PR in NHL were all negative. Conclusion:NHL of breast is extremely rare, and its definite diagnosis depends on various examination methods.

Objective: To explore the cytopathologic features and differential diagnostic essentials of the lung mucosa-associated lymphoid tumor(MALT).Methods: The fine needle aspiration(FNA) tissues and bronchi smears of 4 cases of MALT were examined by cytology,histology and immunohistochemistry respectively.Results: Cytologically,3 of the 4 cases were definitely diagnosed as lymphoid tumor and 1 suspected of small cell undifferentiated carcinoma,while histopathologically,all were diagnosed as MALT.The neoplastic cells were positive for CD20 and CD79a,but negative for CD3,CD5,CD10,CD45RO,CKpan and EMA.Conclusion: MALT is a rare pulmonary lymphoma difficult to be diagnosed.The definite diagnosis of pulmonary MALT depends on the cytology of FNA and bronchi smears,histopathology,and immunohistochemistry.

The clinical data of a child with chemical pneumonia caused by kerosene in Hainan Maternal and Children′s Medical Center in June 2019 were retrospectively analyzed.The patient was a 2 years and 1 month old boy with a history of kerosene inhalation and fever.The clinical features included low breath sounds in the left lung and dry and wet rales in both lungs.The white blood cells (WBC) level, C-reactive protein (CRP) level, and erythrocyte se-dimentation rate (ESR) were significantly increased.Chest CT showed inhalation pneumonia.Chest ultrasound suggested medium pleural effusion on the left side.The patient was given antibiotics, nebulization and other treatment.On the 12 th day of the course of the disease, his temperature returned to normal, and breath sounds on the left side were stronger than before.The WBC level, CRP level and ESR were improved according to the re-check results, but pulmonary ventilation was still obstructed mildly to moderately.Fourteen days after hospital discharge, the patient coughed less.Reexamination of chest CT prompted the lesions were further absorbed, but the mild to moderate obstructive lesions were still observed.With the reduction of kerosene use in daily life, kerosene-induced chemical pneumonia is rare, but due to its diverse and complex clinical manifestations and slow absorption of pulmonary inflammation, attention should be paid to its progression into chronic cough.
