To observe changes on subsets of splenocytes in mice immunized with the transgenic alfalfa (Medicago sativa) vaccine containing Eg95-EgA31 fusion gene of Echinococcus granulosus dynamically,the leaf protein was extracted from the transgenic alfalfa by heat-coagulation method and prepared for a solution with a concentration of 20 g/ L.The 132 BALB/c mice were divided into 3 groups randomly and immunized intranasally or orally with the leaf protein solution once per 3 days for 2 months.At the same time,the group of intranasal immunization with leaf protein from the non-transgenic alfalfa was set as control group.4 mice randomized from each group were killed to get the spleens at Week 0,2,4,6,8,10,12,14,16,18 and 20 after last immunization,and the splenocytes were separated to measure CD_4~+and CD_8~+T cell subsets by FCM.In the oral group,CD_4~+subset increased significantly from Week 6 to Week 10 after the last immunization and reached the peak at Week 6.While CD+ 8 subset increased obviously from Week 4 to Week 12 and reached the highest level at Week 8.In the intranasal group,the significant increase of the CD_4~+subset was observed from Week 4 to Week 6 and also reached the peak at Week 6.The similar trend of CD_8~+ subset was observed from Week 4 to Week 10 and reached the highest level at Week 8.It was suggested that CD+ 4and CD+ 8subsets played an important role in the protection induced in mice immunized with the transgenic alfalfa vaccine.

Objective To study the clinical efficacy and safety of oxymatrine in auxiliary treatment of hepati-tis B virus(HBV) related primary hepatocellular carcinoma (PHC).Methods 345 patients were divided into treat-ment group (174 cases) and control group (171 cases).The control group was given hepatic artery chemoemboliza-tion therapy.The treatment group added with oxymatrine.The near future curative effect of solid tumor and patients'immune function,liver function,the improvement of the quality of life change,and adverse reaction were observed. Results KPS score of the treatment group was better(Z =-3.296,P <0.05),more significant in the near future curative effect of solid tumor (χ2 =4.676,P <0.01).The immune function of the treatment group was significantly improved [ Within group: t(treatment group:CD3) = 2.544, t(treatment group:CD4) =2.446, t(treatment group:CD8) = 2.745, t(treatment group:CD4 /CD8) =2.873,t(treatment group:NK) =2.542,t(control group:CD3) =2.614,t(control group:CD4) =2.337,t(control group:CD8) =2.545,t(control group:CD4 /CD8) =2.336, t(control group:NK) =2.672, P <0.05; Between groups: t(after treatment:CD3) =2.947, t(after treatment:CD4) =2.846,t(after treatment:CD8) =2.943,t(after treatment:CD4 /CD8) =2.879,t(after treatment:NK) =2.798,P <0.01].In the treatment group,the effect was more significant in the improvement of ALT,HBV -DNA,AFP[Within group:t(treatment group:ALT) =2.676,t(treatment group:HBV -DNA) =2.682,t(treatment group:AFP) =2.611,P <0.01,t(control group:ALT) =2.556, t(control group:AFP) =2.523,P <0.05,t(control group:HBV -DNA) =1.216,P >0.05;Between groups:t(after treatment:ALT) =2.417, t(after treatment:AFP) =2.432,P <0.05,t(after treatment:HBV -DNA) =2.674,P <0.01].Two groups appeared adverse reaction after chemotherapy,digestive system and hematopoietic system anomaly,the incidence rates of adverse events in the treatment group were lower than those in the control group (χ2 2 2 white blood cel s decreased =46.969,χthe pain =46.977,χheating =22.499,χ2nausea,vomiting =88.749,P <0.05).Conclusion The oxymatrine auxiliary treatment for HBV related PHC has curative effect,safe and reliable,and can significantly improve the patients quality of life,it is worth promoting.

Objective To explore the correlation between epidermal growth factor receptor (EGFR) gene mutations and computed tomography (CT) characteristics in lung adenocarcinoma.Methods Chest CT scan results of 200 postoperative lung adenocarcinoma patients were retrospectively studied,the EGFR gene mutations detection results were statistically analyzed,and the correlation between EGFR gene mutations status and CT characteristics was investigated.Results Single factor analysis results showed that non smoking,female patients,air bronchogram sign and small tumor diameter were significantly associated with EGFR gene mutations (P＜0.05),and the incidence of GGO in the EGFR gene mutation group was higher than that in the wild group,but no statistical significance was found (P＞0.05),while other clinical and CT signs,such as age,lobulation,spicule,calcification,cavity and pleural indentation were not associated with EGFR gene mutations (P＞0.05).Logistics regression analysis results showed that non smoking and air bronchogram sign were significantly associated with EGFR gene mutations (P＜0.05),but gender and tumor size were not associated with EGFR gene mutations(P＞0.05).Conclusions Non smoking and air bronchogram sign may be used as predictive factors for EGFR gene mutations in lung adenocarcinoma.

Objective:To examine the features of multislice spiral computed tomography (MSCT) in micropapillary-predominant lung adenocarcinomas to improve the understanding of this type of lung cancer. Methods:The MSCT features of 18 cases with micro-papillary-predominant lung adenocarcinoma (micropapillary component>50%) confirmed by histopathology were analyzed retrospec-tively. Results:Among the 18 cases of lung cancer, 1 was diffuse, 3 were central, and 14 were peripheral lung cancer (PLC). The size of the adenocarcinomas in the 14 PLC cases ranged from 1.3 cm to 8.5 cm, with an average of 3.56 cm, including the size of 8 cases greater than or equal to 3 cm. Among the 18 cases, 13 were lobulated, 9 showed spicule signs, 7 showed pleural indentation signs, 5 had pleural adhesions, 1 had bronchial truncation (i.e., cut-off sign), and 4 were surrounded by obstructive inflammation. In addition, calcifi-cation was observed in one case, uneven density in two large lesions, air bronchus sign in four, and solid and ground-glass mixed densi-ty in two. Among the total number of cases, a variety of the measurable enhanced CT values (ΔCT) of lesions were found in 16, ranging from 13 HU to 80 HU, with an average of 47.5 HU, of which 15 were cases ofΔCT≥15 HU and 15 were cases ofΔCT≥20 HU. Pleu-ral thickening was observed in two cases with pleural effusion, and pleural metastasis in one case was confirmed by histopathology. One case with pleural effusion suffering pleural metastasis was confirmed. Ground-glass density nodules in both lungs were observed in one case, with a few bilateral pleural and pericardial effusions. Eight cases had mediastinal or hilar enlarged lymph nodes with uneven density enhancement, and lymph node metastasis was pathologically confirmed in six cases. Lymph node metastasis was found in four cases, but no apparent enlargement of lymph nodes in MSCT was observed. Conclusion:Micropapillary-predominant lung adenocarci-nomas were common in non-smoking elderly female patients, whose lung cancer cases were mostly PLC. The typical features of PLC include lobulation, spicule, and pleural indentation signs. Solid density ranked first in the PLC cases, with evident enhancement and high rate of lymph node metastasis.

Traditionally, Tripterygium hypoglaucum (Levl.) Hutch (THH) are widely used in Chinese folk to treat rheumatoid arthritis (RA). This study aimed to investigate whether the anti-RA effect of THH is related with the gut microbiota. The main components of prepared THH extract were identified by HPLC-MS. C57BL/6 mice with adjuvant-induced arthritis (AIA) were treated with THH extract by gavage for one month. THH extract significantly alleviated swollen ankle, joint cavity exudation, and articular cartilage destruction in AIA mice. The mRNA and protein levels of inflammatory mediators in muscles and plasma indicated that THH extract attenuated inflammatory responses in the joint by blocking TLR4/MyD88/MAPK signaling pathways. THH extract remarkably restored the dysbiosis of the gut microbiota in AIA mice, featuring the increases of Bifidobacterium, Akkermansia, and Lactobacillus and the decreases of Butyricimonas, Parabacteroides, and Anaeroplasma. Furthermore, the altered bacteria were closely correlated with physiological indices and drove metabolic changes of the intestinal microbiota. In addition, antibiotic-induced pseudo germ-free mice were employed to verify the role of the intestinal flora. Strikingly, THH treatment failed to ameliorate the arthritis symptoms and signaling pathways in pseudo germ-free mice, which validates the indispensable role of the intestinal flora. For the first time, we demonstrated that THH extract protects joint inflammation by manipulating the intestinal flora and regulating the TLR4/MyD88/MAPK signaling pathway. Therefore, THH extract may serve as a microbial modulator to recover RA in clincial practice.ver RA in clincial practice.
