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 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 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 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 study the clinical significance of early detection of soluble growth stimulating gene 2 protein (sST2) and prealbumin (PAB) in patients with chronic pulmonary heart disease (CPHD) complicated with refractory heart failure.Methods:From September 2017 to June 2019, 112 CPHD patients complicated with refractory heart failure were admitted to Hengshui People's Hospital. The selected patients met the revised guidelines for the diagnosis and treatment of chronic obstructive pulmonary disease (2013 revision) and the cardiac function grade Ⅲ-Ⅳ according to the grading criteria of the New York Cardiology Society. Cardiogenic shock, severe liver and kidney dysfunction, malignant tumors, anemia, and autoimmune diseases were excluded. Patients were divided into the high PAB group (≥200 mg/L) and the low PAB group (<200 mg/L) according to the PAB level on admission. The pulmonary artery systolic blood pressure (PASP), pulmonary artery mean pressure (MPAP), and left ventricular ejection fraction (LVEF) were observed in the two groups before and after the treatment. PAB, total bilirubin (TBIL), hypersensitive C reactive protein (hs-CPR), N-terminal B type brain natriuretic peptide (NT-proBNP) and sST2 levels were detected. Measurement data were expressed in terms of mean ± standard deviation, the counting data were compared using χ 2 test. Correlation analysis was conducted using Spearman correlation test. Results:There were 40 cases in the high PAB group and 72 cases in the low PAB group. There were no statistically significant differences in general data between the high PAB and low PAB groups ( P>0.05). Hospitalization time was significantly different between the two groups ( P<0.05). Before the treatment, there were no significant differences in PASP, MPAP, NT-proBNP and LVEF between the two groups ( P>0.05). High sST2 was significantly different between the two groups ( P<0.05). After the treatment, PASP, MPAP, NT-proBNP and sST2 were decreased in both groups, and the improvement was more obvious in the high PAB group than in the low PAB group, with statistical significance ( P<0.05). Before the treatment, the levels of TBIL and hs-CPR were not statistically different between the high PAB and low PAB groups ( P>0.05). However, the levels of TBIL and hs-CPR were beyond the normal range. After the treatment, TBIL and hs-CPR were decreased in both groups, and there was statistically significant difference between the two groups ( P<0.05). Spearman correlation analysis showed that PAB was negatively correlated with sST2 ( r=-0.778, P=0.001). There was a positive correlation between cardiac function and sST2 ( r=0.569, P=0.034), hospitalization time ( r=0.572, P=0.033) in patients with refractory heart failure. The higher the sST2 of CPHD with refractory heart failure, the longer the patient hospitalization time, and the more serious the heart failure was. The area under the combined ROC curve of PAB and sST2 was 0.756. CPHD patients with refractory heart failure had the greatest predictive value. Conclusion:The combined test of sST2 and PAB can evaluate the condition and outcome of CPHD patients with refractory heart failure, and guide the clinic.

Intangible cultural heritage （ICH） of traditional Chinese medicine （TCM） and cultural anthropology are closely related in terms of research objects， theories and methods. From the five perspectives of cultural anthropo-logy， namely， cultural function， cultural change， cultural relativism， subject-object position， and holism， this article explained the characteristics， current situation and protection of TCM ICH. It is believed that the multiple functions of TCM ICH should be discovered more comprehensively， and should be guided and applied to further enhance its social value； TCM ICH can not only show the diversity and differences of TCM culture， but also enhance confidence in culture； the main body of ICH should be respected， and analysed and researched with the combination of objective and subjective perspective； at the same time， it should be viewed objectively on the changes of TCM ICH in the new era， and grasp the balance between inheritance and innovation. It is proposed that the main research method of cultural anthropology， i.e. the field survey method， can help to improve the depth and breadth of the research on TCM ICH， so as to protect and inherit TCM in a better way.

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.
