Objective To investigate the correlation between inflammatory cells, body temperature changes, and TCM syndromes of deep venous thrombosis (DVT) patients in acute and subacute phases. Methods The data of age, gender, body temperature, blood routine, venous ultrasonography, and four diagnostic information of 130 DVT patients in acute and subcute phases were collected and analyzed in a cross-sectional study. The correlation between inflammatory cells and the changes of body temperature and TCM syndromes were analyzed. Results Among 130 DVT patients, 37 patients had damp-heat syndrome, 64 patients had blood stasis and dampness syndrome, and 29 patients had qi stagnation syndrome. Neutrophils increased most obviously in blood stasis and dampness syndrome (P<0.05), which had close correlation with the skin redness (OR=1.287, 95%CI: 9.412-21.247). The mononuclear cells increased most obviously in the damp-heat syndrome, which has close correlation with nouhof (OR=7.364, 95%CI:1.189–45.603), high skin temperature (OR=6.683, 95%CI:1.791–24.938), skin tightness (OR=6.107, 95%CI:1.423–26.203) and weakness (OR=3.302, 95%CI: 1.002–9.169). The temperature rising was the most common in the damp-heat syndrome, and the increase of mononuclear cells was the most common one. Conclusion DVT is often accompanied with elevated levels of inflammatory cells and body temperature. Damp-heat syndrome has close correlation with body temperature and mononuclear cells increasing. Dampness and blood stasis syndrome and neutrophils are closely related.

Objective To explore the mechanism of cell apoptosis of immortalized human keratinocytes (HaCaT cells) and protein expression related to this process after long term exposure to sodium arsenite (NaAsO2,1.0 μmol/L).Methods Malignant transformation model was set up through long-term exposure of HaCaT cells to 1.0 μmol/L NaAsO2.Cell passage for 0,1,7,14,21,28 and 35 generations in the process of malignant transformation were collected for measurement of cell apoptosis rate by flow cytometry,and apoptosis related proteins by Western blotting,including activation of cysteine protease 3,8 (cleaved-caspase-3,8),C/EBP homologous protein (CHOP),B-cell leukemia/lymphoma 2 (Bcl-2),and Bcl-2 associated X protein (Bax).Results Along with the arsenite treatment,the apoptosis levels were significantly decreased (F =26.770,all P ＜ 0.05),the apoptosis levels (0.307 ± 0.049,0.213 ± 0.055,0.163 ± 0.057,0.147 ± 0.035,0.053 ± 0.012) of the 7th,14th,21st,28th and 35thgenerations of cells after arsenite treatment were lower than that of control group of the 0th generation (0.393 ±0.021,all P ＜ 0.05).Compared between generations,there were statistical differences of the protein expression levels of cleaved-caspase-3,Chop,Bax and Bcl-2 in arsenite group (cleaved-caspase-3:1.000 ± 0.000,1.030 ± 0.027,1.104 ± 0.069,1.016 ± 0.087,0.838 ± 0.075,0.753 ± 0.082,0.677 ± 0.073;Chop:1.000 ± 0.000,1.059 ± 0.018,0.934 ± 0.095,0.976 ± 0.216,0.793 ± 0.136,0.651 ± 0.042,0.564 ± 0.056;Bax:1.000 ± 0.000,1.069 ± 0.037,1.028 ± 0.042,0.954 ± 0.118,0.641 ± 0.135,0.531 ± 0.132,0.429 ± 0.085;Bcl-2:1.000 ± 0.000,1.072 ± 0.023,1.249 ± 0.134,1.334 ± 0.143,1.633 ± 0.221,1.507 ± 0.152,1.461 ± 0.145,F =7.730,7.355,27.802,12.438,all P ＜ 0.05),compared with control group of the 0th generation (1.000 ± 0.000) and the same generation control group (1.000 ± 0.000),after the 21st generation,the differences were statistically significant (all P ＜ 0.05),while there was no difference of the protein expression levels of cleaved-caspase-8 (F =0.832,P ＞ 0.05).Conclusion In the process of malignant transformation,the apoptosis levels of HaCaT cells are inhibited after long term sodium arsenite exposure through mitochondria and endoplasmic reticulum (ER) stress signaling pathways.

Objective To characterize the imaging features of cerebral vascular fenestrations and the clinical features of patients with cerebral infarction.Methods We retrospectively analyzed the magnetic resonance or CT imaging data of 135 cases of cerebral vascular fenestrations from January 2015 to July 2017 in the First Affiliated Hospital of Fujian Medical University.The location,morphology and the other associated vascular diseases were described.The patients who had cerebral infarction were also analyzed.Results One hundred and thirty-five fenestrations were noted at our institution,129 in arteries,and six in veins,the detection rate being 1.1％ (135/12 232).Basilar arteries were most common,which accounted for 53.3％ (72/129) of the fenestrations.Twenty-eight (20.7％) of these patients had other vascular malformations,with a total of 15 aneurysms,two moyamoya diseases,five venous malformations,two arteriovenous fistulas,and four cavernous hemangiomas.Nine patients had cerebral infarctions,of which five patients had fenestration-relevant cerebral infarctions,and no risk factors for cerebral infarctions were found except fenestration in one patient who was diagnosed with cryptogenic stroke.No acute cerebral infarctions or transient ischemic attack occurred in patients with fenestration-relevant cerebral infarctions who had long-term antiplatelet and statin therapy during follow-up.Conclusions Cerebral vascular fenestrations occur most frequently in the basilar artery and may combine with other malformations.Long-term antiplatelet and statin therapy can be used for cerebral infarctions patients with cerebral vascular fenestrations.

Objective To investigate the clinical characteristics, diagnosis, treatment and prognosis of varicella zoster virus myelitis. Methods The clinical data of 7 varicella zoster virus myelitis patients were retrospectively analyzed and clinical follow-up was conducted. Results Seven patients had characteristic skin rash and symptoms of spinal cord injury. The initial symptoms including rash in 5 cases and spinal cord damage symptoms in 2 cases. The affected skin sections were consistent with the spinal cord segment in 4 cases, and below the level of spinal cord injury in 3 cases. All 7 cases were confirmed by spinal MRI with segmental spinal cord lesions as evidenced by long T1and long T2signals in the affected spinal cord including enhancing lesion in 2 cases. Lesions located in thoracic cord in 5 cases and in cervical cord in two cases.All patients received steroid hormone treatment.Among them,5 patients received additional antiviral treatment. After 12~36 months follow-up, 5 cases were cured, 1 case left with sphincter dysfunction and 1 case with slight numbness of hands. Conclusion Varicella zoster virus myelitis is characterized by characteristic rash and spinal cord symptoms.Antiviral drugs and corticosteroid therapy can yield better prognosis.

Objective To investigate the effects of cyclic stretch on migration of MC3T3-E1 cells and its related mechanism. Methods The strain loading system was used to stretch MC3T3-E1 cells cultured in vitro with 15% amplitude, to simulate the mechanical condition in vivo. The wound healing assay was used to detect the migration of MC3T3-E1 cells. Western blotting was used to test Runx2 expression. RNA interfering was used to decrease Runx2 expression. Results Cyclic mechanical stretch with 15% amplitude, 1.25 Hz frequency and lasting for 24 hours could promote the migration of MC3T3-E1 cells and increase the expression level of Runx2. Runx2 interference inhibited the migration of MC3T3-E1 cells in static culture condition. Interference with Runx2 expression in MC3T3-E1 cells could partially reduce the positive effect of cyclic mechanical stretch on cell migration. Conclusions Cyclic stretch can promote the migration of MC3T3-E1 cells, and Runx2 may play an important role in this process. This study provides experimental basis for finding innovative clinical treatment method to promote fracture healing.

Objective: To study the clinicopathological characteristics of lung salivary gland-type tumors (SGT), and to compare with the corresponding primary SGT in salivary glands. Methods: Twenty-three cases of lung SGT were retrieved from the files of Peking University First Hospital from January 2004 to September 2018. The morphology, immunophenotype, genotype and outcome of these cases were analyzed. Results: The 23 patients included 13 males and 10 females, with age range of 13-79 years (median 54 years). There were 11 cases of adenoid cystic carcinoma, 10 cases of mucoepidermoid carcinoma (MEC), one case each of clear cell carcinoma and myoepithelioma. The morphology and immunophenotype of lung SGT were very similar to their counterparts in salivary gland. MYB rearrangement was detected in one of 11 adenoid cystic carcinomas. MAML2 rearrangement was detected in all the MECs. EWSR1 rearrangement was detected in the one case of clear cell carcinoma. Of patients with adenoid cystic carcinoma, the survival time was more than 60 months (three cases), 52 months (one case), and 12-36 months (three cases). There was no recurrence and death in seven cases of MEC with follow-up results. One case of clear cell carcinoma recurred after 52 months of follow-up. Conclusions Although the SGT of lung and their counterparts in salivary gland are very similar in their morphology, immunophenotype, genotype and prognosis, there are also some differences between each other. MYB rearrangement can be detected in most adenoid cystic carcinomas of salivary gland, but rarely in lung adenoid cystic carcinoma. The prognosis of patients with lung MEC is better than that of patients with salivary gland MEC, while the prognosis of patients with lung adenoid cystic carcinoma is worse than that of patients with salivary gland adenoid cystic carcinoma.
