Hepatic cavernous hemangioma is the most common benign tumor of liver.Hepatic artery embolism chemotherapy is one of the commonly used treatment methods,but more and more related complications and sequelae have been reported recently,including obstructive jaundice caused by damaged biliary tract.Because the symptoms are not typical,obstructive jaundice might be misdiagnosed as malignant biliary tumor,which brought troubles to subsequent treatment.In this article,the clinical data of 2 patients with obstructive jaundice following transcatheter hepatic arterial chemoembolization for hepatic cavernous hemangioma were retrospectively analyzed,and the experience in the diagnosis and treatment of this disease was summarized.

Objective To investigate the effect of Huangqikeli on immune function of mice. Methods 30 mice were randomly divided into 3 groups. The mice in A and B group were administrated with distilled water,C group were administrated with Huangqikeli. On the tenth day,all groups except A group were injected with cyclophosphamide to induce the model. The effects on the phagocytic function of Huangqikeli to macrophage in abdominal cavity of mice,delayed hypersensitivity induced by DNCB,and production of hemolysin antibody in mice that CRBC sensitized were observed. Result Compared with immuno-suppressive models given distilled water (B group),phagocytic function of macrophage in abdominal cavity of mice and delay hypersensitivity leaded by DNCB were enhanced (P

Objective To investigate the effects of continuous hemofihration on gastrointestinal dysfunction for treating patients with intra-abdominal hypertension.Methods A total of 37 patients were divided into two groups randomly (random number),namely control group (n =17) and continuous blood filtration (CBF) group (n =20).The patients of control group were treated with routine treatment,and the patients of CBF group were given CBF for 72 hours in addition to the routine treatment.The intra-abdominal pressure (IAP),gastrointestinal (GI) symptoms,and SOFA score were documented at 0 hour,24 hours,72 hours and 7 days after treatment.Results The MAP of patients in the CBF group was not significantly changed (P =0.218),while the IAP was decreased significantly (P =0.001) and the abdominal perfusion pressure (APP) increased significantly after CBF (P =0.036).Compared with the control group,there were more than 2 GI symptoms markedly relieved after CBF for 24 hours (P =0.049).The SOFA score of CBF group decreased significantly (P =0.037).There were no differences in 28-day and 60-day mortality between two groups.Conclusions The CBF can decrease IAP,increase APP,improve splanchnic blood circulation,and ameliorate gastrointestinal dysfunction.But CBF does not reduce the mortality in comparison with routine treatment.

Objective To construct and express a chimeric gene with T-/B-cell epitopes of the major allergen group 1 from Dermatophagoides farina(Der f 1). Methods Two chimeric genes,Der f 1A and Der f 1B,were synthesized as B1-T1-B2-T2-B3-T3-B4-T4-B5-T5-B6 and B1-B2-B3-B4-B5-B6-T1-T2-T3-T4-T5 pattens. Two recombinant vectors,pET-28a(+)-Der f 1A and pET-28a(+)-Der f 1B,were constructed for prokaryotic expression. These chimeric genes were induced by 1 mmol/L IPTG (final concentration),digested with restriction enzymes and sequenced. The chimeric proteins were analyzed by SDS-PAGE and Western blotting. Results After digestion by restriction enzymes and sequencing,the recombinant vectors were constructed successfully. The specific bands for chimeric proteins were visible by SDS-PAGE and Western blotting,suggesting that these proteins were purified successfully. Further analyses were performed for IgE-binding properties of Der f 1A and Der f 1B to sera from patients sensitized to house dust mite. Compared with the parental allergens Der f 1,Der f 1A and Der f 1B had reduced IgE-binding capacity(both P<0.05),whereas the difference between Der f 1A and Der f 1B was not statistically significant(P>0.05). Conclusion Two chimeric proteins are expressed successfully,which contain T-/B-cell epitopes of Der f 1 and provide a basis for specific immunotherapy.

Objective To investigate the effect of immunotherapy of recombinant chimeric epitopes of major allergen group 1 from Dermatophagoides farina on asthma of mice. Methods Forty mice were randomly divided into 4 groups:a negative con?trol group,an asthma group,an immunotherapy group of Der f 1,and an immunotherapy group of Der f 1A. On the 1st,7th and 14th day,the mice in the asthma group,immunotherapy group of Der f 1,and immunotherapy group of Der f 1A were injected intraperitoneally with the extract of D. farina 3 times to sensitize;and on the 21st day,the atomized inhalation was carried out for 7 days. In the control group,phosphate buffer solution(PBS)was applied for sensitization and inhalation. In the immunother?apy groups,Der f 1 and Der f 1A were applied to carry out the specific immunotherapy respectively for 30 min before the inhala?tion. Then,the leukocytes in the bronchoalveolar lavage fluid(BALF)were numbered and the pathological sections of lung tis?sues were observed;IL?5 and IFN?γin BALF and spleen cell culture supernatants(SCCS)as well as the specific IgE,IgG2a in the sera were detected. Results Compared with the asthma group,the lung inflammation of mice in the immunotherapy groups was lightened,and the total numbers of leukocytes in BALF were significantly reduced;IL?5 was significantly reduced and IFN?γwas significantly increased in BALF and SCCS of mice in the immunotherapy groups;and the specific IgE was significantly re?duced and IgG2a was significantly increased in the sera of mice in the immunotherapy groups(all P<0.01). Conclusion The recombinant chimeric epitopes of major allergen group 1 from D. farina could effectively relieve the symptom of asthma in mice, so as to provide the evidence for specific immunotherapy.

Objective To study the appropriate neck irradiation volume for neck lymph nodenegative nasopharyngeal carcinoma patients by Meta-analysis.Methods The related references published from Jan 1990 to Jun 2013 were searched in Pubmed,Embase,Cochrane and Wangfang Databases.The qualified references for enrollment criteria were screened and the relative data were collected.The OR (Odds ratio) value by fixed effect model was used to evaluate the data for patients who received radiotherapy between the upper neck and whole neck irradiation.The endpoints including 5-year neck local control rate (LCR),neck-in-irradiation LCR,and neck-outsides-irradiation LCR.Results Five qualified references were screened and belonged to respective research.There enrolled 1 333 patients,including 970 patients who received the upper neck irradiation and 363 patients who received the whole neck irradiation,respectively.The forest plots revealed that there were no significant differences for 5-year neck LCR,neckin-irradiation LCR,and neck-outsides-irradiation LCR for patients received radiotherapy between the upper neck and whole neck irradiation.These OR values were 0.89 (95％ CI:0.41-1.94),1.29 (95％ CI:0.58-2.88) and 0.42 (95％ CI:0.07-2.36),respectively.Conclusions The Meta-analysis results suggest that irradiation to the upper neck for neck lymph node-negative nasopharyngeal carcinoma can be appropriate.

Objective To detect beta-human papilloma virus (HPV) and determine its genotype in actinic keratosis (AK) lesions.Methods Tissue specimens were collected from the lesions of 39 patients with AK and normal skin of 40 healthy controls.A nested PCR was performed to detect alpha-HPV and beta-HPV DNA in these specimens.The genotype of beta-HPV was determined in beta-HPV DNA-positive specimens by a common PCR using specific primers targeting 12 HPV genotypes,including HPV 5,8,15,17,19,20,21,23,36,38,49 and 80.Results The detection rate of beta-HPV DNA was 84.6％ (30/39) in the patients with AK,and 30.0％ (12/40) in the healthy controls (x2 =6.76,P ＜ 0.05),while no significant difference was observed in the detection rate of alpha-HPV DNA between the two groups (12.8％ vs.7.5％,x2 =0.91,P ＞ 0.05).HPV 38 was the predominant genotype of beta-HPV in these patients with a detection rate of 36％ (12/33),followed by HPV36.The prevalence of all the 12 genotypes of HPV was consistently low in the healthy controls.Mixed HPV infections were observed in 10 AK lesions,but in none of the healthy controls.No statistical difference was noted in the positivity rate of beta-HPV among patients at different ages,of different genders,with different occupations or clinical courses (x2 =0.53,0.94,0.81,0.73,respectively,all P ＞ 0.05).Conclusions Compared with healthy controls,the patients with AK showed a higher beta-HPV infection rate,with HPV38 as the predominant genotype.
