1.Research advances of human papillomavirus-related head and neck squamous cell carcinoma
Journal of International Oncology 2015;(4):288-291
Recently,the prevalence of human papillomavirus(HPV)infection in head and neck squa-mous cancers has shown an upward trend,especially in the oropharynx squamous carcinoma. This subset of head and neck cancers possesses distinct clinical and laboratory features and outcome,and is particulary com-mon in individuals who lack the traditional risk factors of tobacco and alcohol abuse. The biological markers and treatment of HPV associated head neck cancers are hot topic in current international research.

Chinese Journal of Obstetrics and Gynecology 2000;0(09):-
Objective To summarize the incidence, diagnosis, treatment and prognosis of patients with hemolysis, elevated liver enzymes and low platelet count (HELLP) syndrome. Methods The clinical data of fourteen cases with HELLP syndrome complicated by severe pregnancy-induced hypertension were analyzed retrospectively during the past seven years. Results The incidence of HELLP syndrome was 8% in the patients with severe pregnancy-induced hypertension. According to the diagnosis criteria used by Tennessee University, there were eight cases with complete HELLP syndrome and six cases with partial HELLP syndrome. The major therapeutic way were intensive maternal and fetal monitoring, active management of preeclampsia and eclampsia, administration of corticosteroids and termination the pregnancy as fast as possible. The major complications were DIC, placental abruption, pneumonedema and acute renal failure. The maternal and perinatal mortality were 7% and 29%, respectively. Conclusions HELLP syndrome was a serious life-threatening complication of severe pregnancy- induced hypertension. In order to decrease the maternal and perinatal mortality rate, HELLP syndrome should be diagnosed and treated as fast as possible.

Objective To construct the expression vector and express the recombinant human L-selectin in prokaryotic system, and purify the aimed protein for the preparation of rabbit anti-human L-selectin polyclonal antibody. Methods The partial cDNA of human L-selectin was amplified from the open reading frame (ORF) of N-terminus sequence of L-selectin containing 153 amino acids by PCR, then cloned into the prokaryotic expression vector pQE40 at restriction sites BamH Ⅰ and Hind Ⅲ. The recombinant expression plasmid pQE40-L-selectin was transformed into E. coli M15 for expression. The fusion protein including 6-His-tag was purified by Ni-NTA chromatographic column and analysed by SDS-PAGE. The purified protein was used to immune rabbit for preparing polyclonal antibody. Western blotting analysis and dot immunoblot assay (DIBA) were used to test the titer of the antiserum. Results The expression plasmid pQE40-L-selectin was constructed and confirmed with restriction enzyme digestion. The quantity of the purified protein from E. coli M15 was 600 mg ? L-1. By immuning the rabbit, the polyclonal antibody was successfully prepared. The results of dot immunoblot assay (DIBA) showed that the antiserum had the high titer (1 : 1 000). Conclusion The recombinant human L-seleclin prolein can express with high efficiency in E. coli M15. The prepared polyclonal antibody has a high titer.

lschemic postconditioning(IPo)is a way that after long ischemia on liver graft,animals are given one or several brief reperfusion-ischemia before persistent reperfusion to improve the hepatic tolerance and relieve the ischemie reperfusion injury.It has been proved an effective and controlled method to attenuate the ischemic reperfusion injury.Protective mechanism of ischemic postconditioning on hepatic graft is related with protecting sinus hepaticus endotheliocyte and hepatic microcirculation,relieving hepatic cells injury and inflammatory reaction induced by oxygen free radicals,relieving calcium ovedoad in hepatic cells and mitochondria,regulating apoptosis genes,transforming ion channels condition in mitochondria.This article will makes a brief review on protective mechanism ofhepatic ischemic posteanditioning.

Objective To seek for the best clinical nursing pathway for early limbs activity of patients with high-risk hemiplegia in the department of cerebral surgery and to reduce limbs paralysis and improve their life quality.Methods Patients(112 cases)with high-risk bemiplegia in the department of cerebral surgery from January to December in 2007 were set as the experimental group.They took part in limbs early activity on the first day on admission with application of clinical nursing pathway.Patients(89 cases)of the same kind who took part in limbs activity from January to December in 2006 were set as the control group.The two groups were compared with Brunnstrom scale beth on admission and discharge.Results The Brunnstrom grade of upper limbs,hands and lower limbs of the experimental group was evidently higher than that of the control group(P<0.05).Especially the isolated movement and coordination ability of the hands significantly increased(P<0.01). Conclusions Early limbs activity with clinical nursing pathway for patients with high-risk hemiplegia in the department of cerebral surgery could reach the aim of recovery of limbs functional activity.

Objective:To analyze the clinical materials of the patient with Van Wyk and Grumbach syndrome (VWGS),and to explore the pathogenesis,clinical characteristics,diagnosis,differential diagnosis and treatment method.Methods:The clinical data of a patient with VWGS was analyzed retrospectively.Results:The patient presented autoimmune thyroiditis, sever long-standing hypothyroidism, bilateral ovarian cysts, hyperprolactinaemia and a secondary pituitary adenoma. After thyroxine replacement treatment, the thyroid function and prolactin (PRL)level recovered to the normal levels and the ovarian cyst was shrunk within 1 month. Conclusion:The clinical manifestation of VWGS is special.And it’s easy to misdiagnose this syndrome as pituitary adenoma or ovary cyst and then operation is performed.Thyroid hormone replacement can completely resolve the symptoms and hormone abnormalities.Grasping the clinical characteristics of this syndrome and making correct diagnosis is critical to avoid unnecessary operation.

Aim To study the effects of 2 ,3 ,4 ’ ,5-tet-rahydroxystilbene-2-O-β-D glucoside ( TSG ) on myo-cardial fibrosis ( MF) induced by isoproterenol ( ISO) in mice and its possible mechanism. Methods MF in mice was induced by subcutaneous injection of isoprot-erenol for 14 days. TSG (30,60,120 mg·kg-1 ) and captopril ( 40 mg · kg-1 ) were then administered by gavage to mice. The experiment was stopped 12 h after the last administration of the drugs. Hematoxylin-eosin ( HE) and Masson staining were used to estimate the extent of MF. Level of hydroxyproline in myocardial tissues was measured. Protein expressions of collagenⅠ, collagen Ⅲ and transforming growth factor-β1 (TGF-β1) in myocardial tissues were measured. Lev-els of superoxide dismutase ( SOD ) and glutathione peroxidase ( GSH-Px ) were determined. Results Compared with control mice, the level of hydroxypro-line in myocardial tissues was significantly increased in isoproterenol treated mice. Histological sections of iso-proterenol-treated hearts showed extensive myocardial fibrosis. And protein expressions of collagenⅠand col-lagen Ⅲwere markedly increased in isoproterenol trea-ted mice. However, therapy with TSG decreased the level of hydroxyproline in myocardial tissues, ameliora-ted the degree of myocardial fibrosis, and reduced the collagen expressions induced by isoproterenol adminis-tration. Moreover, treatment with TSG decreased TGF-β1 protein expression and elevated the myocardial SOD and GSH-Px activity. Conclusion TSG can inhibit MF formation induced by ISO in mice which might be due to regulating TGF-β1 protein expression and its an-tioxidant effect.
