Objective To analyze the imaging appearances of the deep-lobe parotid tumors involving the parapharyngeal space (PPS).Methods The CT and MRI data of 23 cases with deep-lobe parotid tumors involving PPS were analyzed retrospectively.The neoplasms included pleomorphic adenomas (n=1 9),basal cell adenomas (n =2),neurilemmomas(n = 1 )and malignant myoepi-thelioma(n=1).Results The lesions presented as oval(n=1 7)or irregular (n =6)masses.None of the 23 cases showed visible fat space between the tumors and deep-lobe of parotid glands.Fat Cap Sign was found in 9 cases.Parotid Pedicle Sign was demonstrated in 8 cases.The styloids were displaced posteriorly(n=4)or surrounded(n=4)by the tumors.Five masses were found to be situated at the superficial side to the posterior belly of the digastric muscle.Carotid sheaths were shifted anteromedially (n=7)or postero-medially(n= 1 1 )by the tumors.Conclusion The deep-lobe parotid tumors involving PPS have some imaging features which are helpful in the differential diagnosis between the deep-lobe parotid tumors and PPS primary tumors.

Objective To explore the molecular basis of vascular endothelial cell's injury by cellular S-adenosylhomocysteine (SAH) accumulation, and the mechanism for cardiovascular disease induced by dietary high methionine intake. Method After human umbilical vein endothelial cells (HUVEC) were treated without (normal) or with different concentrations of potent S-adenosylhomocysteine hydrolase (SAHH) inhibitor 3-deazaadenosine (DZA) for 24, 48 or 72h, the level of intracellular inflammatory monocyte chemoattractant protein-1 (MCP-1) was measured with enzyme linked immunosorbent assay (ELISA). Then, the relative expression of MCP-1 mRNA was detected with quantitative reverse transcription polymerase chain reaction (qRT-PCR). Furtheremore, the methylated state of MCP-1 gene promoter was analyzed with methylation special PCR (MSP) method. Results The level of intracellular MCP-1 was increased in HUVEC incubated with DZA than normal (P

Objective To study the result of DSA for 56 cases with large liver cancer that there is bloody supply from arteria musculophrenica right and the clinical value of super selective interventional embolization,so that to improve the clinical curative effects of interventional therapy. Methods Employ 4F, 3F catheter super selectively into arteria musculophrenica that supply blood to cancer. Result 56 cases(21.7% )were discoverod that there was bloody supply from arteria musculphrenica right to cancer in 258 cases with large liver cancer, liver neoplastic size of all cases wasin 5～15cm,22 cases(8.6% ) were discovered in the first interventional operation,34 cases ( 13.3% )were discovered in the second or the third interventional operation. Obvious tumor shrinking in all cases: the 6month survival as 56 cases(100 % ), the 1-year survival as 45 cases (80.4%), the 2-year survival as 21 cases(37.5%). Conchssion Arteria musculophrenica right supply blood to cancer is common in large liver cancer eases, super selectively embolized the supply blood from the arteria musculophrenica right is very important for acquiring success by interventional operation.

Open hepatectomy(OH) is a effective treatment for benign and malignant liver lesions. However, OH has major abdominal trauma and many postoperative complications. How to reduce OH-induced trauma is still a big problem for liver surgeon. Fortunately, the emergence of laparoscope provides a route to solve this problem. But the technology of laparoscopic liver resection is not yet mature. This article reviews some relevant circumstances about laparoscopic hepatectomy.

Objective To evaluate the effect of Qizhong Granules(QG) on preventing upper respiratory tract infection(URTI) in the elderly through clinical observation.Methods One hundred and forty-nine qualified aged patients were randomized into 3 groups: group A(N =50) received QG,group B(N =49) received Jade Screen Powder(JSP),and group C(N =50) was the blank control group.The treatment lasted 7 continuous days.We observed the incidence of URTI as well as the changes of symptoms and signs on the 7th and 14th day of treatment.Results(1) URTI occurred in 1(2.00%),2(4.08%) and 11(22.00%) patients of groups A, B and C,respectively.The differences between groups A and C,and those between groups B and C were significant(P

Objective To analyze the effect of aspirin combined with clopidogrel in the treatment of patients with cerebral infarction of middle cerebral artery stenosis.Methods 88 patients with cerebral infarction of middle cerebral artery stenosis were selected and divided into group A and B based on the methods of treatment,44 patients in each group.Patients in group A were given aspirin, and patients in group B were given aspirin combined with clopidogrel.The effects of the group A and B were observed and compared.Results The total effective rate of group B was 90.91%,which was higher than 75.00%(33/44) of group A,the difference was statistically significant(χ2 =3.938,P<0.05).The progression rate and relapse rate of group B were 6.82%and 4.55%,which were lower than 27.27%and 20.45%of group A,and the differences were statistically significant(χ2 =7.639,5.091,all P<0.05). The scores of modified Barthel Index and modified Fugl-Meyer in group B were all better than the scores in group A after treatment,and the differences were statistically significant(all P<0.05).Conclusion It is effective for aspirin combined with clopidogrel to treat the patients with cerebral infarction of middle cerebral artery stenosis,which can decrease the rate of progression and relapse,and worthy of clinical application.

[Objective] To investigate the effect of Dengzhan Xixin Injection (DXI) combined with photon-autotransfusion therapy in treating diabetic peripheral neuropathy (DPN). [ Methods ] Sixty-one cases of DPN were randomized into 2 groups. Group A ( n=31) was given DXI 30 - 40 mL (intravenous drip, qd) and photon-autotransfusion therapy (once every 2-3 days). Group B (n = 30) was treated with anisodamine 10 - 20 mg (intravenous drip, qd) and vitamin B] 100 mg and B12 500 ?g (intramuscular injection, qd) . Changes of symptoms and signs and neural conductive velocity were observed to evaluate the curative effect after treatment. [ Results ] The markedly effective rate and total effective rate were 58.07% and 93.55% respectively in group A, which were higher than those in group B (16.67% and 63.34% respectively) , the difference being significant ( P

Objective To investigate the levels of creatine kinase (CK-MB), brain natriuretic peptide (BNP), and neu-ropeptide Y (NPY) in severe pneumonia pediatric patients combined with heart failure (HF). Methods Pneumonia pediatric patients admitted from December 2010 to December 2014 had been enrolled and divided into pneumonia group (P) (n=32), se-vere pneumonia group (SP) (n=20) and severe pneumonia combined HF group (HF) (n=36). Twenty healthy children served as control group (C). Serum level of CK-MB was detected by enzyme rate method and were measured by ELISA. BNP and NPY were measured again during the recovery period in 18 cases in HF group. Results The serum levels of CK-MB, BNP and NPY were signiifcantly different among the four groups, (F=25.19~277.94, P<0.01). The serum levels of CK-MB, BNP and NPY were signiifcantly higher in HF group than in SP, P and C group (P<0.05). The serum level of CK-MB was signiifcantly higher in SP group than that in P and C group (P<0.05) and there was no difference between P and C group (P>0.05). The serum levels of BNP and NPY were not statistically signiifcant between SP and P and C group (all P>0.05). In HF group, the serum levels of CK-MB, BNP, and NPY were signiifcantly decreased in 18 cases after treatment. The serum level of BNP was positively correlat-ed with CK-MB and NPY (r=0.681, 0.525, all P<0.01) and the NPY and CK-MB levels were also positively correlated (r=0.545, P<0.01). Conclusions The Detection of the serum levels of CK-MB, BNP and NPY can help diagnose severe pneumonia com-bined with HF. The BNP maybe the most sensitive indicator.
