Objective To explore the clinical features and urgent treatment strategies of open stabbing and penetrating wound of the heart. Methods In recent five years, 22 cases of cardiac trauma patients were sent to our emergency department, among them 19 sustained penetrating wounds produced by sharp instruments, 3 with perforating wounds, produced by firearm in 2 and sharp instrument in one. Emergent thoracotomy was performed in all the patients. The injury involved right auricle in 4, left auricle in 1, right ventricle in 11, left ventricle in 3, and perforating wounds of both right and left ventricles in 3 patients. Results Among them 19 survived, and their cardiac and pulmonary recovered 2 weeks after the operation. Three patients with injury of the great vessel died, one of them died 8 hour after the operation. Conclusion When the patients who presented open wounds on the anterior or posterior chests, showing a low or undetectable blood pressure, which could not raised even with fluid resuscitation with two venous lines or in some of them displaying signs of Beck's triad, open cardiac injury should be seriously suspected, and emergent thoracotomy should be taken in order to rescue the patients.

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.

Objective To assess the diagnostic significance of T cell receptor gamma gene rearrangemerits in mycosis fungoides (MF), so as to develop a sensitive diagnosis tool. Methods A total of 50 specimens were collected, including 33 skin lesion specimens and 2 lymph specimens from 30 patients with MF,15 skin lesion specimens from 15 patients with inflammatory dermatoses. PCR was performed with specific primers targeting TCR V gamma 8, 9, 10, 11 to detect T cell receptor gamma gene rearrangement. 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 explore the clinical manifestations, electroencephalographic characteristics and therapeutic effect of drugs in children with Jeavons syndrome. Methods The clinical and electroencephalographic characteristics and thera-peutic effect of drugs were analyzed in 4 children with Jeavons syndrome. Results Among the four children there were 3 female and 1 male. The age at the onset of the disease was from 1 to 6 years. The typical clinical manifestations of this disease were brief, fast and repeated eyelid myoclonia (EM) with or without absence seizure. The typical electroencephalography (EEG) in two patients showed 3-6 Hz generalized spike and waves and polyspikes burst, and the eye closure and intermittent photic stimu-lation helped to induce discharges and clinical events. The typictal EEG in the other two patients showed 3.0-3.5 Hz generalizedδslow wave rhythm burst. The drugs of choice for treatment was sodium valproate monotherapy in two cases, levetiracetam in one case, sodium valproate combined with levetiracetam in one case. During the follow-up, seizures were controlled in one case, decreased in frequency in two cases and were still frequent in one case. Conclusions Jeavons syndrome is one of the idiopathic and generalized epileptic syndromes and characterized by EM with or without absence seizure. Video EEG monitoring plays an important role in the diagnosis of this disease. Sodium valproate and levetiracetam were effective for this disease.

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.

Objective To investigate the expression of serum platelet factor 4 (CXCL4) in high-grade intraepithelial neoplasia (HGIN) of gastric cardia and its clinical significance. Methods Sixty-four HGIN patients and 29 patients with advanced cardiac cancer (ACC) from January 2010 to December 2011 in the Fourth Hospital of Hebei Medical University were selected as the research objects. Forty healthy people treated with endoscope screening were chosen as the control group. Enzyme linked immunosorbent assay (ELISA) was used to detect the expression of CXCL4 in serum. The expression differences were compared by using variance analysis and LSD-t. Results The CXCL4 detection showed that the expression levels of CXCL4 were(0.75±0.37)ng/ml,(0.87±0.33)ng/ml,(1.13±0.51)ng/ml respectively in HGIN group,ACC group and the control group (F = 10.77, P < 0.05). The CXCL4 expression levels in HGIN and ACC group were lower than that in the control group (t = 4.80, t = 2.67, both P < 0.05). There was no difference between the CXCL4 expression levels in HGIN and ACC group(t =1.27,P >0.05).Conclusions The expression level of CXCL4 in HGIN patients with gastric cardia is significantly decreased. CXCL4 may be related with the occurrence and angiogenesis of gastric cardia cancer, which can be considered as an important serum marker for early screening of gastric cardia cancer.

Aim To explore the role of ERO1 αand its DNA methylation in homocysteine (Hcy)-induced in-hibition of hepatocytes proliferation.Methods The hepatocytes stimulated with 0 μmol·L -1 Hcy were set as the normal group (NC group)and the hepatocytes stimulated with 1 00 μmol·L -1 Hcy as the experimen-tal group (Hcy group).Methyl thiazolyl tetrazolium (MTT)reduction assay was used to reflect the prolifer-ation of the hepatocytes;qRT-PCR and Western blot were used to detect the mRNA and protein levels of ERO1 α;the expression of green fluorescence protein was observed in hepatocytes after the recombinant plas-mid of ERO1 α was constructed,which was used to confirm if the recombinant plasmid into hepatocytes was successful,then the mRNA and protein levels of ERO1 αwere assayed and the proliferation of the hepa-tocytes was also detected;ntMSP was used to detect the change of ERO1 αDNA methylation.Results The mRNA and protein levels of ERO1 αwere decreased in Hcy group compared with NC group,and the prolifera-tion activity of hepatocytes in Hcy group was de-creased.Sequencing result showed that the recombi-nant plasmid of ERO1 αwas constructed successfully. QRT-PCR and Western blot revealed that ERO1 αwas overexpressed. The result of MTT suggested that ERO1 αoverexpression restored hepatocyte proliferation inhibited by Hcy.Hcy caused ERO1 αDNA hyperm-ethylation.Conclusions Hcy inhibits hepatocyte pro-liferation by downregulating the expression of ERO1 α, and methylation of ERO1 αpromoter may play a role in this process.
