IrritabIe boweI syndrome( IBS)is caused by muItipIe factors,and the pathogenesis has not yet been cIarified. RecentIy,the roIe of brain-gut axis based bio-psycho-sociaI medicaI modeI in the pathogenesis of IBS has been wideIy accepted. Brain-gut axis forms a nerve-endocrine-immune network mediating bidirectionaI reguIation pathway,which pIays an important roIe in maintaining homeostasis between centraI nervous system and gut. Brain-gut axis abnormaIities may Iead to imbaIance of the homeostasis and subsequentIy induce the occurrence of IBS. This articIe reviewed the advances in study on brain-gut axis dysfunction in pathogenesis of IBS.

Aim To investigate the effect of TRPV4 on hepatic fibrosis of rats . Methods Liver fibrosis model of rats was induced by 50% CCl4 twice a week for 12 weeks. HE and Masson staining were used to evaluate the degree of hepatic fibrosis, and the levels of α-smooth muscle actin(α-SMA) and TRPV4 were detec-ted in fibrotic liver tissue by Western blot. HSC-T6 cells were activated by transforming growth factor β1 (TGF-β1),and the protein levels of α-SMA, TRPV4 were detected by Western blot. After using Ru and transfected with TRPV4-siRNA, HSC-T6 was stimula-ted with TGF-β1, the levels of α-SMA, TRPV4 and phosphorylation level of Akt were determined by West-ern blot. Results TRPV4 was highly expressed in model liver tissues and in activated HSC-T6 induced by TGF-β1 . The levels of α-SMA and phosphorylation of Akt decreased in TGF-β1-induced HSC, used with Ru or transfected with TRPV4-siRNA. Conclusions The expression of TRPV4 increases in fibrotic livers and ac-tivated hepatic stellate cells. Knockdown of TRPV4 can suppress the activation of hepatic stellate cells in-duced by TGF-β1 , and decrease the phosphorylation levels of Akt.

Objective To establish the acute hind limb ischemia on Wistar rat with diabetes mellitus.MethodsThirty diabetes rats were induced by intraperitoneal STZ (50 mg/kg) injection, as well as the blood glucose level tested over 16.8 mmol/L. The rats were ligated on the left femoral artery, then the blood perfusion on the hind limbs ischemia was measured by LDPI after the operation. Results The fasting plasma glucose level on 22 Wistar rats(81.5%) was kept above 16.8 mmol/L, and the hind limb blood perfusion would recover slowly to the level of the right side from 1 to 14 day (P

Objective To explore the effective method for preserving laryngeal function in the treatment of laryngeal cancer of T3 lesions. Methods Utilizing unilateral pedicled muscle-periosteal flap, 32 cases with laryngeal carcinoma of T3 lesions underwent extended vertical partial laryngectomy for laryngeal cavity structure after one-stage reconstruction. Results With 1-3 years postoperative follow-up, the patients had good pronunciation, unobstructed respiration and no tumor recurrence, with extubation rate of 100%. Conclusion It showed that treating patients with laryngeal carcinoma of T3 lesions with extended vertical partial laryngectomy using unilateral pedicled muscle-periosteal flap reconstruction for laryngeal cavity structure can remove tumor effectively and obtain the satisfactory respiratory pronunciation function. The method has a good clinical application prospect.

Diabetic retinopathy is one of the serious complications of diabetes, is currently the world's second largest blinding disease. Early epidemiological data showed that the development is related to blood sugar level, diabetes duration, blood lipids, and other factors. In recent years, the correlation of gene polymorphism with DR received widespread attention. Accurately grasp the genetic mechanism in the process of development in the DR and the differences of expression, is of great significance to DR early diagnosis and prevention. So in this article, the progress of gene of DR were reviewed.

To study the clinical application of Jintian'ge capsule in treatment of vertebral compression fracture in senile osteoporosis patients. In the study, 69 senile osteoporotic vertebral compression fracture patients hospitalized in our hospital between January 2012 and June 2014 were selected and randomly divided into the control group and the treatment group. Patients in the control group were treated by percutaneous kyphoplasty (PKP), while those in the treatment group were given Jintian'ge capsule in addition to PKP. Efforts were made to visit the patients before the surgery and in three month after that, observe and compared the vertebral height, Cobb's angle, bone density, visual analogue scale (VAS) and Oswestry disability index between patients in the two groups. According to the findings, compared with before the treatment, patients in the two groups showed significant improvements in the vertebral height, Cobb's angle, bone density, VAS and Oswestry disability index three months after the surgery (P < 0.05); During the visit three months after the treatment, compared with the control group, the treatment group showed notable increases in all parameters (P < 0.05), particularly in the vertebral height, VAS and Oswestry disability index (P < 0.05). Based on the above findings, Jintian'ge capsule is applicable in adjuvant therapy after the osteoporotic vertebral compression facture PKP surgery.

Objective To study the preparation and properties of alkalized shikonin liposome.Methods Alkalized shikonin was purified from extracts of radix lithospermi with an alkali solution and acid formulation, and then the alkalized shikonin liposome was prepared by ethanol injection.The morphology, particle size and Zeta potential were determined, and the encapsulation efficiency and the in vitro release property were investigated.The content of L-shikonin was also measured by High Performance Liquid Chromatography.Results Alkalized shikonin liposome presented even sphere and normal distribution with particle size of 104.2nm.The Zeta potential was-14.8mV.L-shikonin was linear in the range of 5-50mg/L with the correlation coefficient 0.999 9.The encapsulation efficiency was 43.67％.The final release rate was 65.82％.Conclusion Alkalized shikonin liposome was prepared successfully with good entrapment efficiency and in vitro release property.

OBJECTIVETo investigate the differential plasma protein profiles in patients with hyperlipidemia & atherosclerosis (H&A) of different patterns of phlegm-stasis syndrome (PSS) for seeking their biomarker proteins.

METHODSTwo-dimensional gel electrophoresis and gel screening graphical analysis were performed on plasma proteins got from 146 patients; corresponding protein spots were fetched from the gel for two-stage mass-spectrometric analysis by quadruple time-of-flight mass spectrometry; then the differential proteins for PSS were discriminated by Fisher discriminate analysis.

RESULTSExcepting two uncertain proteins, 7 differential proteins were screened out from the 11 differentially expressed plasma protein spots with variability over 100% in the inter-block matching. Classic analysis found that haptoglobin precursor and fibrinogen gamma chain were possibly the plasma biomarker proteins for H & A; fibrinogen beta chain and apolipoprotein A-I precursor were that set apart PSS from non-PSS; fibrinogen gamma chain, albumin and apolipoprotein A-I precursor were for phlegm syndrome; haptoglobin precursor, adrenomedullin binding protein precursor, albumin and complement component C4 were for stasis syndrome; albumin and adrenomedullin binding protein precursor were for the phlegm-stasis mutual blocking syndrome. Moreover, the above mentioned expressions of possible marker proteins had their own special rule of changing in the transforming progress of PSS.

CONCLUSIONThis study reported, for the first time, the existence of evident variation of functional protein constitution in different patterns of PSS, and definite compatibility being detected in some functional proteins, which may be the marker proteins for making diagnosis and prognosis of PSS in H&A. Besides, preliminary proof for the transformation of PSS has gained at the functional protein level.
