1. Preparation of HBc virus-like particle vaccine harboring sequences of gastric inhibitory peptide and its immune effects
Academic Journal of Second Military Medical University 2010;30(11):1230-1235
Objective: To design and prepare HBc virus-like particle vaccine (VLP) harboring the specified epitope of gastric inhibitory peptide (GIP), and to study its immune effects, so as to cast new lights on immune therapy of obesity. Methods: GIP cDNA was cloned and was fused with HBc VLP (1-144aa) cDNA. Through prokaryotic expression and purification processes, a GIP vaccine linked to the HBc-derived VLP carrier was constructed. We also cloned the fusion gene into eukaryotic vector pVAX1 to prepare GIP nuclear acid vaccine. And the two kinds of vaccines were tested in rats for their immunological parameters. Results: GIP vaccine linked to HBc-derived VLP carrier was successfully prepared. We also prepared the genetic vaccine pVAX1-HBc-GIP. The combined vaccination with both vaccines could obtain high titer and peptide-specific IgG antibody, displaying a satisfactory immunogenicity. Conclusion: GIP protein vaccine using HBc as immune-enhancing vaccine carrier can effectively induce GIP-specific humoral immunity, disrupting the tolerance to self antigens in rats. The vaccine is worth studying as a new drug for control of obesity.

Objective To explore the effect of community comprehensive rehabilitation on quality of life in patients with stroke sequelae under the family medical service mode. Methods From October, 2013 to October, 2014, 51 patients with stroke sequelae received compre-hensive rehabilitation intervention for three months, including rehabilitation training, rehabilitation guidance, health education and psycho-logical counseling. They were assessed with modified Barthel index (MBI), WHO-Disability Assessment Schedule (WHO-DASⅡ), Short Form 36 Health Survey Questionnaire (SF-36), Brain Injury Community Rehabilitation Outcome Scales (BICRO-39), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) before and after intervention. Results The scores of physical functionning, role physical, general health, mental health, social functioning and the total score in SF-36 increased after intervention (t>2.072, P<0.05). The scores of so-cial contact, locomotivity, self handling transaction ability and the total score in BICRO-39 decreased after intervention (t>2.434, P<0.05), as well as the scores of getting along with people, housework and society and participation in WHO-DAS II (t>2.507, P<0.05). Conclusion In the community health service, comprehensive rehabilitation guided by multidisciplinary rehabilitation team can facilitate to improve the quality of life in patients with stroke sequela.

OBJECTIVETo analyze effects of fracture of processus styloideus ulnae on prognosis in the treatment of distal radial fracture of type C according to AO classification.
METHODSThis was a retrospective case-control study, and the information was got ten through case evaluation and follow-up, including sex, age, patient satisfaction, Gartland & Werley score and radiographic score. There were 76 patient treated with open reduction and plate fixation in People's Hospital Affiliated to Peking University from July 2006 to July 2011. All the patients were divided into two groups: no combination with fracture of processus styloideus ulnae (group A, 56 cases), combination with fracture of processus styloideus ulnae (group B, 20 cases). The patients in group A and B were treated with open reduction and internal fixation; however the fracture of processus styloideus ulnae was not fixed. The indexes such as clinical data, bone grafting, joint movement, Gartland & Werley score and radiographic score were compared between two groups.
RESULTSThe ulnaris pain of patients in group B was more obvious than that in group A. The local VAS, palmar and dorsal flexion degree of wrist joint, motion VAS, patients satisfaction score, radial and ulnar deviation degree, pronation and supination of forearm degree, Gartland & Werley score and radiographic score were separately 0.1 ± 0.1, (51.1 ± 1.9)°, (60.2 ± 1.9)°, 0.6 ± 0.1 (23.1 ± 0.9)°, (28.7 ± 1.3)° (81.5 ± 2.6)°, (68.2 ± 2.7)° 1.9 ± 0.3, 89.6 ± 12.3 in group A; and separately 0.3 ± 0.3, (51.4 ± 2.3)°, (66.6 ± 1.7)°, 0.5 ± 0.2, (24.5 ± 2.0)°, (26.9 ± 1.8)°, (80.3 ± 2.5)°, (70.3 ± 3.7)°, 1.2 ± 0.4, 92.5 ± 7.5 in group B; there were no statistical differences in above indexes between two groups.
CONCLUSIONWhether the distal radial fracture with a concomitant unrepaired ulnar styloid fracture or not exerts no influence on mainly outcomes including function, radiography and motion of the wrist.

Objective Through detecting the expression of erbB-2 and erbB-3 of epithelial growth factor receptor family in clinical specimens of salivary adenoid cystic carcinoma, to explore the role of erbB-2 and erbB-3 in the carcinogenesis and development of salivary adenoid cystic carcinoma. Methods Thirty-four specimens of adenoid cystic carcinoma were tested with immunohistochemical assay. Then the relationship between the expressions of erbB-2, erbB-3 and the gender, age of patients, TNM staging, tumor size and nerve invasion were analyzed.Results The positive expression ratios of erbB-2 and erbB-3 were 64. 7% and 32.4% respectively. And 29.4% of tumors were positively stained both by erbB-2 and erbB-3. The expression of erbB-3 was significantly correlated with TNM staging of tumors (P = 0. 026). The correlationship between the expressions of erbB-2 and erbB-3 was also found. Conclusions erbB-3 and erbB-2 may play important roles in the carcinogenesis and development of salivary adenoid cystic carcinoma. The positive expression of erbB-3 was associated with the biological behavior of tumors and prognosis of patients, and might become one of markers to evaluate the prognosis of patients.

OBJECTIVETo study the effect of Feiji Recipe (FR) intervening indoleamine 2,3-dioxygenase (IDO) induced immune escape on the murine model of Lewis lung carcinoma. Methods Totally 48 C57BL/6 mice inoculated with Lewis lung cancer cells transfected with human (enhanced green fluorescent protein,EGFP)-IDO gene were divided into four groups according to radom digit table, i.e., the model group (administered with normal saline by gastrogavage) , the Chinese medicine group (treated with FR Decoction at the daily dose of 100 mg/g by gastrogavage), the 1-methyl-D-trytaphan (1-MT) group (administered with 1-MT mixed liquor at the daily dose of 100 mg/kg by gastrogavage), and the Paclitaxel group (treated with Paclitaxel at the daily dose of 15 mg/kg by peritoneal injection), 12 in each group. The intervention was started from the 2nd day of modeling. The survival time was observed in 24 of them. Ratios of CD4+ CD25+ FoxP3+ regulatory T cells (Treg) in the spleen were detected in the rest 24 mice by flow cytometry respectively.
RESULTSCompared with the model group, the survival time was significantly prolonged in the Chinese medicine group and the 1-MT group (P < 0.01); ratios of Treg cells remarkably decreased in the Chinese medicine group, the 1-MT group, and the Paclitaxel group (P < 0. 01). Compared with the Paclitaxel group, the survival time was significantly prolonged in the Chinese medicine group and the 1-MT group (P < 0.01); ratios of Treg cells decreased significantly in the 1-MT group (P < 0.05).
CONCLUSIONFR could inhibit the proliferation of lung cancer cells and immune eseape, improve the immune function, and prolong the survival of tumor-bearing mice.

This study is to investigate the effect and mechanism of puerarin on DNA damage of HaCaT cells induced by UVB. Puerarin pre-treated cells were irradiated with UVB at 30 mJ x cm(-2). Twenty four hours after irradiation, DNA damage was detected by comet assay, ceramide was measured by thin layer chromatography and gas chromatography, intracellular free calcium ion was analyzed by flow cytometry, the phosphorylation level of p38 protein was examined by Western blotting method. Levels of DNA damage, ceramide, free calcium ion and p-p38 protein were elevated in UVB model cells. Contrary to the model group, all indicators above were reduced in all groups pre-treated by puerarin. Puerarin restrains the ceramide accumulation to block downstream p38 MAPK pathway and calcium ion rising, therefore reduces DNA damage in HaCaT cells induced by UVB.
