Objective To preliminarily explore the expresssion of the Hedgehog signaling pathway (HH) after different liver trauma, and provide basis for the blockaded effection of HH and the potentiality of new traditional Chinese medicine exploition. Methods After adaptive breeding for one week, a cohort of 140 male SPF Fisher 344 rats were randomly divided into Retrorsine injection (R) indicated the toxical of chemical damage of liver, partial hepatectomy (PH) indicated the acute liver trauma, retrorsine/partial hepatectomy (R/PH) for the hepatic stem cells regeneration, and normal control (N) groups. The administering of retrorsine or placebo, and PH or sham operation were performed as Gordon’s matheds. RT-PCR, real-time PCR and immunohistochemistry were performed to detect the expression of the constituents related to HH after liver damage. Results RT-PCR demonstrated that the mRNA expression of IHH, PTCH, Smo, Gli1, Gli2, Gli3 were all activated in primary liver cells after different kinds of liver damage. The results of real-time PCR analysis indicated an interaction effect existing between the treatment and the time in 3 Hedgehog-related constituents (signaling molecule IHH, indicators of the HH activation Ptc, Gli1) (all P<0.001). The protein expression of PTCH in liver tissue section was confirmed by immunohistochemistry, which differed in the duration in PH and R/PH groups. Conclusion The HH was abnormally activated during the different liver trauma. It’s maybe an important signaling pathway during the liver’s reaction after damage.

Objective The anterior-lateral defect of foot that lost one of the three supporting point of foot can lead to collapse of the lateral longitudinal arch, overload of the first metatarsal heads, and painful callus formation. It is meaningful to investigate the effect of reconstructing the lateral forefoot defect with pedical fibular osteoseptocutaneous flap. Methods From March 1989 to June 2008, there were 38 patients with anterior-lateral defect of foot were constructed. The supporting point with the local distal based pedical fibular osteoseptocutaneous flap was constracted. Results All the 38 flaps survived. All 38 patients had been followed up from 6 months to 10 years (mean 23.5 months) postoperatively. The constructed supporting point of the foot was functional. The patients could walk freely with no pain, and was satisfied with the operation. Assessed with the rating system for foot and ankle established by the American Orthopaedic Foot And Anke Society, 8 patients got a score above 85, 23 patients between 75 to 85, 7 patients between 60 to 75. Conclusion It is effective that transferring local distal based pedical fibular osteoseptocutaneous flap to repair the anterior-lateral defect of foot.

Objective To evaluate the clinical effect of acupuncture on Parkison disease (PD) with systematic review in view of evidence-based medicine (EBM).Methods Articles on clinical effect of acupuncture on Parkinson disease published from the database-established year to May of 2017 we searched from China National Knowledge Internet (CNKI),Wanfang,VIP,Chinese Biomedical Literature Database (CBM),PubMed,and Cochrane Library databases without language limitation.Quality evaluation and data extraction were carried out according to the tool for assessing risk of bias provided by the Cochrane Handbook for Systematic Reviews of Interventions (Version 5.1.0).All statistical analyses were performed with Reviewer Manager Software (Version 5.3;Cochrane Collaboration,Oxford,UK).Assessments were performed with the total effective rate,the scores of each scale (the unified Parkinson disease rating scales-UPDRS and the Webster scale),and the improvement of different clinical manifestation.Results In all,12 randomized controlled trials (RCTs) met our inclusion criterion,a total of 892 patients,including 468 cases in the experimental group (acupunctuer with or without medicine) and 424 cases in the control group (medicine only).Meta-analysis showed favorable results for the experimental group compared to control group in the total effective rate,the total scales of UPDRS and the modified Webster scale [OR =2.16,95％ CI (1.57,2.97),P＜0.01;OR =7.20,95％ CI(4.02,10.37),P＜0.01;OR=3.33,95％ CI(2.13,4.53),P ＜0.01].The experimental group was effective in relieving partial symptoms of PD such as rigidity,postural,gait,bradykinesia compared to the control group,while there was no significant difference in tremor at rest and sit-stand up movements (P ＞ 0.05).Conclusions Acupuncture had certain clinical effect on Parkinson disease,it can relieve the clinical symptoms of Parkinson disease to some extent,and postpone the progression of PD,which improves the quality of life of PD patients.Acupuncture can be recommended as a combination treatment for Parkinson disease.

The delta-opioid receptor (DOR),which is a classic analgesic drug widely existed in the central system and peripheral system,is a kind of inhibitory G-protein coupled receptor with seven transmembrane regions.In addition to pain modulation,the opioid receptors are involved in various physiological and pathological activities through gene or cytokines.This review addresses the influence and possible mechanisms of the delta-opioid receptor in ischemic brain injury,analgesia,anti-anxiety and depression,learning and memory,and Parkinson's disease.

Parkinson's disease (PD) is a neurodegenerative disease characterized by degeneration and deletion of dopaminergic neurons in the substantia nigra and a pathological feature of the Louis body.The clinical manifestations including non motor symptoms and motor symptoms.Cognitive impairment (CI)is one of the most common non motor symptoms in patients with PD,Which includes mild cognitive impairment (MCI) and dementia.MCI is an early manifestation of dementia in PD.Therefore,early diagnosis and treatment of MCI are very important for the prognosis of PD.The epidemiology,risk factors,heredity,biomarkers,imaging,diagnosis and treatment of MCI in PD are reviewed in this paper.

Ceramide (Cer) is a second messenger produced by the degradation of plasma membrane phospholipids in cells. It is an essential lipid mediator for normal cellular function, composed of sphingosine and different chains of fatty acids. Its receptors are widely present in red blood cells, endothelial cells, glial cells, immune cells, and nerve cells, and participate in various pathophysiological processes such as oxidative stress, inflammatory response, signal pathway transduction, and immune regulation. Many studies have confirmed that the increase of Cer level is related to cardiovascular disease, type 2 diabetes and lipid metabolism. Ceramide score can be used as a tool to evaluate the severity and prognosis of cardiovascular events. However, there is limited research on the impact of Cer on acute ischemic stroke (AIS). This article aims to elucidate the role of Cer and its impact on the occurrence, development, and prognosis of AIS.
