ABSTRACT
Objective@#To explore the characteristics of pain sensitivity of autism spectrum disorder (ASD), and to provide reference for clinical comprehensive intervention of ASD.@*Methods@#A case-control study was conducted to investigate the characteristics of pain sensitivity in 142 ASD children and 142 normal children using the items related to pain sensitivity in the Autism Treatment Evaluation Checklist (ATEC). In addition, two recognized ASD model mice (BTBR mice and model mice induced by VPA) were selected as experimental group. The thermal pain threshold and mechanical pain threshold of BTBR mice were measured by electroshock seizure threshold and Von Frey filament test, and the differences of pain characteristics between BTBR mice and control mice were compared, the thermal pain threshold of model mice induced by VPA (VPA rats) was measured by electroshock seizure threshold, and the differences between BTBR mice and control mice (Con) were compared.@*Results@#There was significant difference in pain sensitivity between ASD group and control group (χ 2=0.81，P<0.05), and the sensitivity of ASD children to pain was significantly lower than that of normal control children. The pain sensitivity of BTBR mice and C57BL/6 mice on the 42 nd day after birth was measured. The T-test analysis showed that the time taken for BTBR and C57BL/6 mice to retract their feet on the 42 nd day after birth (3.62±0.38,3.02±0.33)s (t=3.28,P<0.01), and the mechanical pain threshold (9.75±3.58,0.55±0.93)s (t=7.44,P<0.01). The detection of thermal stinging pain in VPA rats and con rats on the 9 th, 11 th, 13 th and 15 th day after birth was detected. The results of t test were as follows:P9(11.34±1.38,9.81±1.64)g, P11(11.37±1.98,9.36±1.11)g, P13(11.53±1.38,9.51±1.01)g and P15(12.05±2.91,8.74±1.60)g (t=-2.79,-2.25,3.95,3.95,P<0.05).@*Conclusion@#Compared with normal control children, ASD children show insensitivity to pain which is further supported by two types of animal models for ASD.
ABSTRACT
Objective To investigate the correlation between the severity of alcoholic fatty liver disease and the amount of fat in the abdominal cavity and the serum inflammatory factor IL-18 and IL-8. Methods From October 2016 to October 2017,one hundred and twenty patients with AFLD in the First Hospital of Hebei Medical University were divided into light,medium,heavy groups according to the severity of fatty lesions by color Doppler Ultrasound. There were 40 mild patients,50 moderate patients and 30 severe patients. Forty healthy subjects were selected as controls. All the participants underwent CT scanning. The intra-abdominal fat area (VAT),abdominal subcutaneous fat area (SAT) and total abdominal fat area (TA) were measured. The liver function was measured by biochemical analyzer and enzyme-linked immunoassay (ELISA). (ELSIA) IL-18 was detected and IL-8 was detected by radioimmunoassay. Results The VAT of the healthy control group and the mild,medium and severe AFLD group were (70. 28±10. 19),(114. 38 ± 9. 97),(146. 73±10. 19),(163. 38±12. 69) cm2. The TA of the healthy control group and the mild, medium and severe AFLD group were ( 256. 72± 34. 56),( 332. 19 ± 33. 28),( 387. 49± 32. 28),( 478. 19 ±31. 02) cm2.

Aspartate aminotransferase (AST) of the healthy control group and the mild,medium and severe AFLD group were (18. 50±1. 12),(23. 50±1. 21),(25. 50±1. 24),(29. 50± 1. 43) U/L. Alanine aminotransferase (ALT) of the healthy control group and the light, medium and severe AFLD group were ( 18. 50 ± 2. 14), ( 26. 50 ±2. 22),(35. 50±2. 34),(38. 50±2. 11) U/L. γ-glutamyltransferaseof the healthy control group and the light,medium and severe AFLD group were ( 16. 50 ± 2. 11), ( 32. 50 ± 2. 23), ( 47. 50 ± 2. 31), ( 48. 00 ±2. 43) U/L,respectively. Compared with the healthy control group,VAT,TA,SAT,AST,ALT andγ-GT in the light,medium and heavy AFLD group showed statistically significant differences ( P＜0. 05) . Compared with the mild AFLD group, VAT, TA, SAT, AST, ALT and γ-GT in the medium and heavy AFLD group showed statistically significant differences ( P＜0. 05) . Compared with the moderate AFLD group,the VAT, TA,SAT, AST, ALT, and γ-GT of the severe AFLD group showed statistically significant differences ( P＜0. 05). The data of the three AFLD groups showed that the concentration of all indicators were increasing as the severity of fat deepened. IL-18 of the healthy control group and the light,medium and severe AFLD group were (45. 67±4. 51),(52. 18±5. 09),(59. 87±4. 98),(64. 18±5. 12) ng/L; IL-8 of the healthy control group and the light, medium and severe AFLD group were ( 78. 92 ± 5. 07), ( 115. 62 ± 4. 89), ( 223. 76 ± 6. 78),(286. 42±7. 02) g/L. Compared with every group,IL-18 and IL-8 of light,medium and severe AFLD group showed statistically significant differences (F＝1035. 67,2. 93×105,P＜0. 001); compared with mild AFLD group,IL-18 and IL-8 of medium and heavy group showed statistically significant differences;compared with moderate AFLD group,IL-18 and IL-8 of severe group AFLD showed statistically significant differences ( P＜0. 001) . The levels of inflammatory factors IL-18 and IL-8 increased with the severity of steatosis. The severity of AFLD was significantly positively correlated with VAT,TA,SAT,IL-18 and IL-8 ( r 0. 415(P＜0. 001), 0. 435 ( P＜0. 001), 0. 512 ( P＜0. 001), 0. 274 ( P＜0. 001 ), 0. 689 ( P ＜0. 001). Conclusion Fat control is an important measure to prevent AFLD. IL-18 and IL-8 can reflect the severity of liver injury in AFLD and have important significance in judging prognosis.
ABSTRACT
BACKGROUND:Umbilical cord mesenchymal stem cells are plentifully and conveniently obtained with a high proliferative ability, and have opened up a new way to treat patients with liver failure as they can differentiate into hepatocyte-like cells.OBJECTIVE:To observe the safety and efficacy in the treatment of chronic liver failure by transplanting umbilical cord mesenchymal stem cells.METHODS:Using parallel contrast method, 50 patients with chronic liver failure were divided into two groups, namely a stem cell group and a control group, containing 25 patients in each group. For the first group, transplantation of umbilical cord mesenchymal stem cells, (1.4-2.3)×106/kg, 100 mL, was given on the basis of medical comprehensive treatment,while for the second group only simple medical comprehensive treatment was given. The injection was done every 15 days, totally three times. Liver functions, prothrombin activity, Model for End-Stage Liver Disease (MELD) score, clinical symptoms, survival and side effects of the patients were observed before and 2, 4, 12 and 24 weeks after the treatment.RESULTS AND CONCLUSION:Compared with the control group, the albumin level and prothrombin activity were significantly increased in the stem cell group 12 and 24 weeks after treatment (P 0.05). Four weeks after treatment, clinical symptoms of the stem cell group improved significantly in comparison with the control group (P < 0.05).During the 24-week follow-up, the survival rate in the stem cell group was significantly higher than that in the control group (P < 0.05). Additionally, there were no adverse reactions and liver cancer associated with the stem cell therapy.Results show that it is safe and effective to treat patients with chronic liver failure through the transplantation of umbilical cord mesenchymal stem cells, and the cell transplantation can significantly improve patients' survival rate.

ABSTRACT
BACKGROUND:How to make more transplanted bone marrow stem cel s stay and differentiate in the liver is an important issue, which is also crucial for treatment of liver cirrhosis via the hepatic artery. OBJECTIVE:To investigate the therapeutic effect of autologous bone marrow stem cel transplantation via the hepatic artery on liver cirrhosis. METHODS:Thirty New Zealand white rabbits were equivalently randomized into normal control, stem cel transplantation and model groups. Animal models of liver cirrhosis were made in the latter two groups. Then, model rabbits in the stem cel transplantation group were subjected to autologous bone marrow stem cel transplantation via the hepatic artery. Liver function of rabbits was detected in 1, 2, 4, 8, 10 weeks after cel transplantation, and pathological detection of the liver was performed in the 10th week. RESULTS AND CONCLUSION:At 10 weeks after cel transplantation, the liver function of the rabbits was improved significantly compared with the model group, including reduced activities of serum alanine aminotransferase, total bilirubin and aspartate aminotransferase, shortened activated partial thromboplastin time, and increased albumin level (P<0.05). Pathological examination of the liver showed that the liver cel s in the stem cel transplantation group were intact with no obvious edema and stil had the structure of the pseudolobule, and compared with the model group, the degree of liver fibrosis was significantly reduced in the stem cel transplantation group. Our experimental results show that the transplantation of autologous bone marrow stem cel s via the hepatic artery has a certain therapeutic effect on liver cirrhosis by increasing the body albumin content in a short time and improving the liver function.
