Objective To evaluate the change of elasticity of rabbit liver following portal inflow vessels occlusion using acoustic radiation force impulse (ARFI). Methods Twelve Japanese white big ear rabbits were used to establish total hepatic vascular exclusion animal models by occluding the portal inflow vessels. The elasticity of rabbits' right liver was detected during the stages of baseline(T0), 5 min(T1),20min(T2) ,30min (T3)after occluding the portal inflow vessels using ARFI respectively. The elasticity of rabbit liver, levels of serum's aspartate aminotransferase (AST), alanine aminotransferase (ALT) and historical results of hepatic tissue during different stage were compared. Results Shear wave velocity(Vs)of rabbits' right livers in T2 was significantly higher than that in T0 ( P <0.05) and Vs of rabbits' right livers in T3 was significantly higher than that in T2 ( P <0.05). No significant differences of serum's AST,ALT levels between T2 and T0 were found,while the Vs of rabbit live in T2 was slightly higher than that in T0 (P>0.05), serum's AST, ALT levels in T3 were significantly higher than that in T2 ( P <0.05).Historical changes of liver ischemia and injury were observed in T2 and T3 with light microscopy. Conclusions The liver ischemia and injury severity can be accurately and objectively evaluated using ARFI.

Hepatocellular carcinoma(HCC)is the fourth leading cause of cancer-related death,following lung cancer,colorectal cancer and gastric cancer.Chemoresistance is currently the major challenge in clinical treatment of HCC patients,and it is also the primary cause of the poor prognosis and high recurrence rate of patients.There are multiple factors and complex mechanisms in the occurrence of HCC drug resistance.Recent research has shown that non-coding RNA(ncRNA)is closely related to HCC chemoresistance.By regulating the expression of target genes and protein translation,ncRNA affects the occurrence,metastasis,and prognosis of HCC and is expected to become a therapeutic biomarker and potential drug therapeutic target for HCC.Therefore,this study reviews several common ncRNAs,including long non-coding RNAs(LncRNAs),miRNAs and transferRNA(tRNAs),in the molecular mechanisms and research progress of HCC chemoresistance,providing new ideas for solving the problem of HCC chemoresistance.

OBJECTIVETo compare the effects between acupuncture with regulating mind and spleen and wes-tern medication for diarrhea irritable bowel syndrome (IBS-D).
METHODSEighty-one patients were randomly at the ratio of 2 to 1 assigned into an acupuncture group (54 cases) and a western medication group (27 cases). Acupuncture with regulating mind and spleen was applied in the acupuncture group for 6 weeks at Baihui (GV 20), Yintang (GV 29), Tianshu (ST 25), Zusanli (ST 36), Shangjuxu (ST 37), Sanyinjiao (SP 6), and Taichong (LR 3), once every other day, 3 times a week. Pinaverium bromide tablet was used orally in the western medication group for 6 weeks, 50 mg a time, 3 times a day. IBS symptom severity score (IBS-SSS) were observed before and after 1-week, 6-week treatment. Pittsburgh sleep quality index (PSQI) was applied before and after 6-week treatment. Also, clinical efficacy was evaluated in the two groups.
RESULTSThree patients dropped out in the acupuncture group, and 1 in the western medication group. Except abdominal distension score after 1-week treatment in the western medication group, single scores and total scores of IBS-SSS apparently reduced in the two groups after 1-week and 6-week treatment (<0.01,<0.05). After 1-week treatment, the abdominal pain score of the acupuncture group was obviously lower than that of the western medication group (<0.05). After 6-week treatment, with abdominal pain relief advantage, other results including the number of pain days, defecation satisfaction,life disturbance degree and total score of the acupuncture group were obviously lower than those of the wes-tern medication group (<0.01,<0.05). After 6-week treatment, the PSQI score and its change before and after treatment in the acupuncture group were superior to those in the western medication group (both<0.05). The relief rate and relief plus obvious effective rate in the acupuncture group were higher than those in the western medication group[51.0% (26/51) vs 19.2% (5/26),<0.01; 64.7% (33/51) vs 34.6% (9/26),<0.05].
CONCLUSIONSAcupuncture with regulating mind and spleen for diarrhea irritable bowel syndrome can more effectively relieve abdominal pain than pinaverium bromide tablet at the early stage. Its total effect and single effects are better at the later stage on abdominal pain, seizure frequency, defecation satisfaction, life disturbance, and sleep quality.

AL3810, a molecular dual inhibitor of the vascular endothelial growth factor receptor (VEGFR) and fibroblast growth factor receptor (FGFR), has earned the permission of phase II clinical trial for tumor treatment by China FDA. As a reversible ATP-competitive inhibitor, AL3810 targets ATP-binding site on intracellular region of VEGFR and FGFR, whereas, AL3810 lacking interplay with extracellular region of receptors rendered deficient blood-brain tumor barrier (BBTB) recognition, poor brain penetration and unsatisfactory anti-glioma efficacy.
