Objective:To investigate the changes and clinical significance of body mass index (BMI), blood lipid and fat soluble vitamin levels in patients with different types of severe preeclampsia.Methods:Sixty-eight pregnant women with severe preeclampsia who received antenatal examination in Lishui Maternal and Child Health Care Hospital, China from February 2017 to February 2019 were included in the study group. According to the onset time, the pregnant women were divided into an early onset group (≤ 34 weeks of gestation, n = 38) and a late onset group (> 34 weeks of gestation, n = 30). An additional 50 healthy pregnant women who concurrently received antenatal examination in the same hospital were included in the control group. Serum levels of triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), vitamin A (VA), vitamin E (VE) and vitamin D 3 (VD 3) were determined in all pregnant women. Logistic regression was used to analyze severe preeclampsia-related influential factors. Results:There were no significant differences in age, number of births and number of pregnancies among the three groups (all P > 0.05). BMI and serum levels of VA, VE, TC, TG, and LDL-C were (22.99 ± 4.39) kg/m 2, (0.48 ± 0.08) ng/mL, (11.91 ± 1.74) ng/mL, (4.93 ± 0.34) mmol/L, (1.57 ± 0.26) mmol/L, (2.68 ± 0.27) mmol/L, respectively, which were significantly higher than those in the control group [(20.68 ± 3.68) kg/m 2, (0.40 ± 0.07) ng/mL, (10.32 ± 2.56) ng/mL, (4.12 ± 0.67) mmol/L, (1.25 ± 0.32) mmol/L, (2.15 ± 0.32) mmol/L, t = 3.725, 6.698, 4.352, 8.731, 6.282, 10.512, all P < 0.05]. Serum levels of HDL-C and VD 3 in the study group were (1.51± 0.32) mmol/L and (16.16 ± 2.37) ng/mL, respectively, which were significantly lower than those in the control group [(1.88 ± 0.57) mmol/L, (17.86 ± 2.39) ng/mL, t = - 6.959, - 4.520, both P < 0.05]. BMI and serum levels of TC, TG, LDL-C, VA and VE in the early onset group were (23.13 ± 4.13) kg/m 2, (5.05 ± 0.34) mmol/L, (1.62 ± 0.27) mmol/L, (2.95 ± 0.32) mmol/L, (0.52 ± 0.06) ng/mL, (12.16 ± 1.80) ng/mL, respectively, which were significantly higher than those in the control group ( t = 6.507, 17.462, 11.217, 16.593, 9.075 and 4.142, all P < 0.05). Serum levels of HDL-C and VD 3 in the early onset group were (1.43 ± 0.28) mmol/L and (15.76 ± 2.42) ng/mL, respectively, which were significantly lower than those in the control group ( t = 14.635, 5.871, both P < 0.05). BMI and serum levels of TC, TG and VE in the late onset group were (22.70 ± 4.32) kg/m 2, (4.67±0.32) mmol/L, (1.49 ± 0.25) mmol/L and (11.45 ± 1.61) ng/mL, respectively, which were significantly higher than those in the control group ( t = 5.821, 12.857, 8.059, 3.482, all P < 0.05). Serum level of VD3 in the late onset group was (16.72 ± 2.31) ng/mL, which was significantly lower than that in the control group ( t = 4.319, P = 0.01). There were no significant differences in serum levels of LDL-C, HDL-C and VA between late onset group and control group (all P > 0.05). There were no significant differences in BMI, and serum levels of TC, TG, HDL-C, LDL-C, VA, VD 3 and VE between early onset and late onset groups (all P > 0.05). Logistic regression analysis results revealed that BMI and serum levels of TG, TC, HDL-C, LDL-C, VA, VD 3 and VE are independent influential actors of early onset severe preeclampsia ( P = 0.000, 0.008, 0.032, 0.043, 0.032, 0.002, 0.041, 0.009). BMI and serum levels of TG, TC, VD 3 and VE are independent influential actors of late onset severe preeclampsia ( P = 0.002, 0.016, 0.013, 0.031, 0.042). BMI, blood lipid and fat soluble vitamin in combination are of high value for the prediction of early onset severe preeclampsia (sensitivity 87.81% and specificity 76.67%), but they are not of high value for the prediction of late onset severe preeclampsia (sensitivity 52.51% and specificity 55.10%). Conclusion:BMI, serum lipid and fat soluble vitamin in combination are of high value in the prediction of early-onset severe preeclampsia.

Objective To detect the infection rate of human papillomavirus (HPV) types in keratoacanthoma (KA) tissue, and to study the distribution of HPV DNA-positive cells. Methods In situ hybridization was performed to detect HPV subtypes 6/11, 16/18, and 31/33 in paraffin-embeded tissue samples from 46 patients with KA and 34 nomal human controls. Results Mucosal HPV DNA was positive in 31 (67.39%)of the 46 KA samples, and mixed infection rate of HPV amounted to 83.87% (26/31) in these positive samples.The DNA of tested mucosal HPV types existed mainly in episomal status. Positive reactions were observed within or at the edge of nuclei. HPV infected cells showed a stripe-, slice-like or focal distribution mainly in superficial middle lamina of spinous layer at the bottom or lateral margin of crater-shaped epidermal depression. No mucosal HPV DNA was noted in normal control samples. Conclusions Compared with normal controls, patients with KA are infected with mucosal HPV at a higher frequency, and mucosal HPV DNA mainly exists in episomal status in KA tissue, hinting that HPV infection play a certain role in the pathogenesis of KA.

Results Monoclonai rearrangements of TCR gene was observed in 88% (29/33) of specimens from patients with MF and 33% (5/15) of samples from patients with inflammatory dermatoses. Conclusions The detection of TCR gene rearrangements, as an ancillary test, is useful in the diagnosis and differential diagnosis of MF.

Objective: To examine the effect of SiO2 exposure on the airway surface microenvironment and NIMA-related kinase 7 (NEK7)/nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 (NLRP3) inflammasome in rats. Methods: Twenty-four specific pathogen-free male rats of the SD strain were randomly divided into the control group and the model group, of 12 rats in each group. Rats in the model group were given SiO2 suspensions through disposable tracheal intubation perfusion to model silicosis in rats, while rats in the control group was perfused with the same amount of physiological saline. The pH value and glucose level were measured in the rat bronchoalveolar lavage fluid (BALF) 14 and 28 days after modeling. Lung tissues were stained with HE and Masson and the distribution of inflammatory cells and the deposition of pulmonary interstitial collagens were observed in lung tissues under a light microscope. The expression of transforming growth factor β1 (TGF-β1), collagen type Ⅰ(ColⅠ), collagen type Ⅲ (Col Ⅲ), interleukin-1β (IL-1β), NLRP3, N-terminal domain of Gasdermin D (GSDMD-NT), caspase-1, and NEK7 was quantified in lung specimens using immunohistochemistry. Results: Lower pH values were measured in rat BALF in the model group than in the control group 14 [(6.38±0.05) vs. (6.68±0.08), P<0.05] and 28 days after modeling [(6.63±0.14) vs. (6.86±0.05), P<0.05], while higher glucose levels were seen in the model group than in the control group 14 [(0.39±0.06) vs. (0.31±0.04) mg/dL, P<0.05] and 28 days after modeling [(0.39±0.08) vs. (0.31±0.06) mg/dL, P<0.05]. HE and Masson staining showed mild to moderate alveolitis and pulmonary fibrosis in rats 14 days post-exposure to SiO2, and showed moderate to severe alveolitis and pulmonary fibrosis 28 days post-exposure. Immunohistochemistry detected higher TGF-β1, ColⅠ, Col Ⅲ, IL-1β, NLRP3, GSDMD-NT, caspase-1 and NEK7 expression in rat lung tissues in the model group than in the control group (all P<0.05). Conclusions SiO2 exposure may cause changes in rat airway surface microenvironment, including BALF acidification and elevated glucose. Pyroptosis induced by activation of NEK7-associated NLRP3 inflammasome may be an important mechanism of pulmonary fibrosis caused by silicosis.

Objective:To determine the relationship between serum resistin levels and carotid intima media(IMT)thickness in patients with essential hypertension. Methods:This study consisted of 272 patients with essential hypertension. The patients were divided into three groups according to their serum resistin levels. Group 1,n=91,serum resistin level 1.233-3.701 ng/ml;Group 2,n=91,serum resistin level 3.728-8.777 ng/ml;and Group 3,n=90,serum resistin level 8.809-28.658 ng/ml. Results:The carotid IMT and maximum carotid IMT of Group 3 were the highest in three groups.(P＜0.05).As shown in multivariate analysis for factors affecting carotid IMT,serum resistin level(β=0.220,t=5.793,P=0.000)was independently associated with the carotid IMT after controlling the age,blood glucose,uric acid,low-density lipoprotein cholesterol,systolic blood pressure and diastolic blood pressure. Serum resistin level(β=0.189,t=4.733,P=0.000)was independently associated with the maximum carotid IMT after controlling the age,blood glucose,body mass index,diastolic blood pressure,diabetes mellitus,high sensitivity C reactive protein,total cholesterol and triglyceride. Conclusion:Serum resistin was independently associated with the increased carotid IMT in essential hypertension patients.

Aim To investigate the role of miR-125 b and its DNA methylation in homocysteine ( Hcy )-in-duced vascular smooth muscle cells( VSMCs) prolifera-tion. Methods VSMCs were stimulated with 0,50, 100, 200, 500 μmol · L-1 Hcy respectively. Then qRT-PCR was used to detect the mRNA levels of miR-125b,and nested-touchdown methylation-specific PCR ( ntMS-PCR) was used to detect the methylation levels of miR-125b. VSMCs were transfected with miR-125b precursor or the inhibitor of miR-125b ,then 3-(4,5-dimethylthiazol-2-yl)-2-5-diphenyl tetrazolium bromide ( MTT ) assay was used to reflect the proliferation of VSMCs. The distribution of CpG islands of miR-125b promoter region was analyzed by bioinformatics meth-ods. VSMCs were stimulated with 100 μmol·L-1 Hcy and transfected with or without DNA methylation inhib-itors 5-nitrogen impurity cytidine ( AZC) , then the ex-pression of miR-125b was detected by qRT-PCR. Re-sults The mRNA levels of miR-125 b were decreased in 100,200,500 μmol·L-1 Hcy group compared with 0 μmol·L-1 Hcy group. The precursor of miR-125b could inhibit the proliferation activity and the inhibitor of miR-125 b could increase the proliferation activity of VSMCs cells. Bioinformatics analysis indicated that MiR-125 b promoter region had a CpG island whose length was 792 bp ( 1881-2672 ) . The miR-125 b pro-moter region methylation levels increased after Hcy in-tervention ( P <0. 01 ) . The expression level of miR-125 b increased after AZC intervention ( P <0. 05 ) . Conclusions ① Hcy promotes vascular smooth mus-cle cell proliferation maybe by down-regulating the ex-pression of miR-125b. ② Hcy down-regulates the ex-pression of miR-125 maybe by up-regulating the methy-lation levels of miR-125b promoter region.
