Objective To investigate the effects of Schistosoma japonicum infection on selective activation of macrophages and insulin resistance in liver tissues of mice with high-fat diet induced obesity and the possible mechanism. Methods Thirty-six male C57BL/ 6J mice were randomly divided into 3 groups in-cluding normal control group(NC group,n=12),high-fat diet feeding group(HF group,n=12)and high-fat diet feeding with Schistosoma japonicum infection group(HSj group,n=12). Specimens were collected 6 and 12 weeks after high-fat diet feeding. The levels of fasting blood glucose(FBG),fasting plasma insulin (FINS)and homeostasis model assessment for insulin resistance index(HOMA-IR)were detected. The ex-pression of interleukin-6(IL-6),arginase-1(Arg-1)and found in inflammatory zone-1(Fizz-1)at mRNA and protein levels were detected by semi-quantitative reverse transcription polymerase chain reaction(RT-PCR)and immunohistochemistry,respectively. Results The mice from HF group showed higher levels of HOMA-IR than those form NC group and HSj group by the end of 6 and 12 weeks after infection(P﹤0. 05). The levels of HOMA-IR in mice from HF group were increased by the end of week 12 after infection as com-pared with those at week 6(P>0. 05). The levels of IL-6 in mice from both HF group and HSj group were higher than those from NC group by the end of week 6 after infection(P﹤0. 05). Higher levels of IL-6 were detected in mice from HF group as compared with those from HSj group and NC group by the end of week 12 after infection(P﹤0. 05). The expression of Arg-1 and Fizz-1 in mice form HF group were lower than those from NC group by the end of 6 and 12 weeks after infection(P﹤0. 05). Arg-1 was highly expressed in mice form HSj group,followed by those from NC and HF groups 12 weeks after infection. The expression of Fizz-1 in mice from HSj group was the highest among the three groups by the end of week 6 and 12 after infection (P﹤0. 05). Conclusion The proinflammatory effects on mice with diet induced obesity were induced dur-ing acute infection of Schistosoma japonicum cercariae(6 weeks). The chronic infection of Schistosoma ja-ponicum cercariae(12 weeks)might be helpful in reversing hepatic insulin resistance in mice with diet in-duced obesity by changing the polarity of macrophages in liver tissues.

Objective To evaluate the biological characteristics of hip joint in infants with developmental dislocation of the hip (DDH).Methods From January 2013 to June 2016,30 patients (age from 1 to 8 months,25 females and 5 males) who were diagnosed as DDH,underwent ultrasound examination in Shenzhen Children's Hospital,in these patients 20 cases were treated surgically,and 10 cases were treated with non-surgical treatment.There were 34 hips (26 unilateral dislocation and 4 bilateral dislocation) dislocation in 60 hips.All the patients were confirmed by X-ray,magnetic resonance imaging (MRI) examination or operation.All the patients were examined by ultrasound through the coronal and transverse plane of the hip joint.The α angle,femoral head coverage ratio by acetabulum (FHC),femoral head length and width,distance from pubis to femoral head (P-H) and distance from ischium to femoral head (I-H) were measured.The dislocation joints were compared with contralateral joints.Results The α angle in the hip dislocation group was smaller than the contralateral group [(50.5±3.75)° vs (64.8±3.38) °],and there was significant difference between the two groups (t=-15.181,P ＜ 0.001).The FHC,femoral head length and width in the hip dislocation group were all smaller than the contralateral group [(23.4t17.63)％ vs (64.3±6.45)％,(0.98 ±0.15) cm vs (1.19 ±0.11) cm,(1.38±0.21) cm vs (1.61 ±0.16) cm],and there were significant differences between the two groups (t=-12.469,-6.034,-4.568,all P ＜ 0.001).The P-H and I-H in the hip dislocation group were larger than the contralateral group [(0.97±0.45) cm vs (0.27±0.05) cm,(0.75±0.30) cm vs (0.17±0.05) cm],and there were significant differences between the two groups (t=8.805,10.696,both P ＜ 0.001).The α angle,femoral head length and width in bilateral dislocation of hip group were slightly smaller than the unilateral dislocation of hip group [(50.3±2.75)° vs (51.3±4.77)°,(0.90 ±0.15) cm vs (0.97 ±0.12) cm,(1.25±0.20) cm vs (1.37 ±0.17) cm],but there were no significant differences between the two groups.The P-H and I-H in bilateral dislocation of hip group were slightly larger than the unilateral dislocation of hip group [(0.97 ± 0.49) cm vs (0.80±0.31) cm,(0.92±0.26) cm vs (0.68±0.18) cm],but there were no significant differences between the two groups.The value of acetabular index in the ultrasound group was slightly larger than the X-ray group [(33.13 ± 7.82)° vs (31.20 ± 8.31)°],and there were no significant differences between the two groups.Conclusions The characteristics of DDH includes acetabulum and femoral head dysplasia,and femoral head and acetabulum position relationship abnormalities.Quantitative ultrasonography of the hip can be used to quantitatively evaluate the structural features of DDH,and it is helpful to the early diagnosis and follow-up of DDH.

OBJECTIVETo explore the improvement of dendritic cells' (DCs) functions in chronic hepatitis B (CHB) patients by two different drugs plasma, i.e., Shen supplementing and detoxification (SSD) and Pi invigorating and detoxification (PID), thus comparing which method was more effective to activate DCs to improve T lymphocyte functions.

METHODSTotally 30 CHB outpatients were recruited. They were assigned to the immune tolerant group and the immune clearance group, 15 in each group. Totally 60 mL peripheral blood was extracted to isolate and develop mature DCs. Chinese compound containing (Liuwei Ganlu Syrup for SSD) and (Sijun Ganlu Syrup for PID) plasma were added to promote the maturation of DCs on the 7th day. Besides, non-drug plasma was taken as the control. On the ninth day, HBV core 18-27 loaded core peptide and its own T lymphocyte were co-cultivated for 72 h. Then T lymphocytes were collected. The expression levels of CD3, CD28, CD4, and CD8, programmed death-1 (PD-1) were detected using flow cytometry.

RESULTSCompared with non-drug plasma, the expression levels of CD3, CD4, and CD28 could be improved, and the expression levels of CD8 and PD-1 could be reduced by the two methods, showing statistical difference (P < 0.05). Besides, SSD containing plasma showed better effect in improving the molecular CD28 expression rate, and reducing the molecular PD-1 expression rate on the T cell surface, showing statistical difference when compared with that of PID containing plasma (P < 0.05).

CONCLUSIONSIn vitro intervention of DCs by SSD and PID containing plasmas combined co-cultivation of its own T lymphocytes could promote the activation of DCs to improve the function of T cells and the expression of T cell surface molecules. Besides, SSD showed more significant effect on infection immune of HBV patients in the tolerance stage.

Objective To explore the features of autonomic nerve function in reflux esophagitis (RE) patients, and the role of abnormal function in the pathogenesis of RE. Methods Twenty RE patients (RE group) and 18 healthy controls (HS group) all underwent heart rate variability (HRV) with meal stimulation to test the function of autonomic nerve. At same time, the endoscopic Los Angeles (LA) Classification, RE symptom score, Gastroesophageal reflux disease-health related quality of life (GERD-HRQL), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were evaluated in the RE patients. Of those, 12 RE patients were re-examined the function of autonomic never after 2 to 4 months [mean (3.7±0.8) months] of proton pump inhibitors (PPI) treatment. Results In fasting state, the sympathetic activity was higher in RE group than in HS group, while the parasympathetic activity was lower in HS group (P=0.022 and 0.034). Postprandial, the trend of autonomic functional change was the same in RE group and HS group. Postprandial, the sympathetic activity was negatively correlated with symptom score in RE patients; however, the parasympathetic activity was positively correlated with RE symptom score. The influence of meal on the balance of sympathetic and parasympathetic was negatively correlated with RE symptom score (r=-0.48, P=0.022). The influence of meal on the parasympathetic nerve was positively correlated with RE symptom score and GERD-HRQL score. After PPI treatments, RE symptom score, GERD-HRQL score, SAS score and SDS score were all significantly decreased in RE patients. There was no significant difference in autonomic nerve function before and after PPI treatment. Conclusions There is abnormal autonomic nerve function in RE patients, characterized by higher sympathetic activity and lower parasympathetic activity in fasting state. The autonomic nerve function is correlated with RE symptom score. The abnormal autonomic nerve function may be one of the causes of RE.

Objective To study the effects of platelet activation on the metastasis and prognoies of lung cancer. Methods Radio-immunity and ELISA were employed to detect the TXB_2,DH-TXB_2,TSP, β-TG, GMP-140,CGMP and FN of 168 cases of lung cancer patients (lung cancer group) and 80 cases of healthy persons control group. The lung cancer group included two subgroups: earlier and metaphase group (n=51) and advanced group (n=17), 39 cases in the former group underwent operation (after operation group). Results (1)Compared with control group, the levels of DH-TXB2,TSP,β-TG,GMP-140,CGMP in group of earlier and metaphase lung cancer increased and FN decreased. TXB2,DH-TXB2,TSP,β-TG,GMP-140,CGMP in advanced group increased and FN decreased;DH-TXB2 and GMP-140 increased in group of after operation. (2)Compared with group of earlier and metaphase lung cancer,the levels of DH-TXB2,TSP,β-TG,GMP-140,CGMP in group of after operation increased and FN decreased; In advanced group, levels of TXB2, DH-TXB2,TSP,β-TG,GMP-140,CGMP increased and FN decreased. (3)In the lung cancer group, CGMP was positively correlated with DH-TXB2,TSP,β-TG and GMP-140. (4)Compared with control group,TXB2, DH-TXB2, TSP,β-TG,GMP-140 and CGMP in group glandular cancer and small cell carcinoma cases increased,FN decreased;In squamous cancer, the levels of TXB2, DH-TXB2,GMP-140 and CGMP increased and FN decreased. (5)Compared with small cell carcinoma cases, DH-TXB2 decreased in cases of glandular cancer; GMP-140 decreased in squamous cancer. Conclusions Activations of platelet generally emerged with lung cancer patients, platelet activation was severe in advanced cancer patients. Activations of platelet, after operation, is obviously eased. The level of platelet activation marker is possibly related with histological classification of lung cancer.
