Vitamin D adjusts the body′s absorption and utilization of calciumand phosphorus. Vitamin D deficiency is closely related to incidence of many disease. Several disorders,both systemic and those of the nerv-ous system,have been linked with vitamin D deficiency. Neurological disorders with a vitamin D link include but are not limited to multiple sclerosis,Alzheimer and Parkinson disease,as well as cerebrovascular disorders. In re-cent years,studies have found that the vitamin D may play a critical role in the pathogenesis of epilepsy and pos-sess certain anticonvulsant effects. This article summarized the role of vitamin D in the nervous system and epi-lepsy,the level of serum vitamin D and the correlation of the polymorphism of its receptor genes with epilepsy. The review also summarizes the interaction between antiepileptic drugs and vitamin D.

Hepatocellular carcinoma(HCC) is the fifth most common cancer and the third cause of cancer-related death worldwide;meanwhile,it is also one of the fastest growing malignancies.The causes of HCC are multiple;HBV is the most important cause in China,with about 25%-30% of HBV infection patients finally develop hepatic cirrhosis and liver cancer.At present,large scale epidemiological studies revealed that the metabolic syndrome(MS) was closely related to liver cancer,and it even served as an independent risk factor for the occurrence and progression of liver cancer.Non-alcoholic fatty liver disease is a metabolic syndrome clinically manifested in the liver;recently it has been indicated to be closely related with HCC development and progression.This paper reviews the recent researches on metabolic syndrome and liver cancer,so as to provide literature for preventive and therapeutic studies on non-virus-related liver cancer.

Objective To investigate ulnar impaction syndrome imaging characteristics and wrist arthroscopy in the diagnosis and treatment effects.Methods From September 2006 to April 2014,41 patients with ulnar impaction syndrome were treated.Of all 41 patients,28 were male and 13 female with an average age of 34.5±3.9 years old (ranging from 15 to 52 years old).The preoperative values of wrist range of motion (ROM) were 44.17°±6.22° at volar flexion,42.72°±3.37° at dorsal extension,17.45°±4.11° at radial deviation,19.12°±3.70° at ulnar deviation,66.81°±4.28° at pronation,and 70.27°±5.30° at supination.Arthroscopic exploration was conducted in all patients,aiming to observe the ulnar variance,wrist osteonecrosis,articular cartilage damage and triangular fibrocartilage complex tear.Arthroscopic synovectomy were performed in all cases;33 cases of articular cartilage injury were treated with arthroscopic chondroplasty;16 cases of osteonecrosis were treated with arthroscopic drilling decompression;30 cases with tear of TFC were treated with arthroscopic repair;26 cases with ulna positive mutation were treated with arthroscopic distal ulna resection.Patients were followed at 3,6,and 12 months after operation.At 12 months follow-up,the values of wrist range of motion was evaluated for volar flexion,dorsal extension,radial deviation,ulnar deviation,pronation,and supination.GreenO'Brien method was used to evaluate the function of wrist joint.Results Primary healing was presented in all patients without neurovascular injury and joint infection.All patients were followed up 12-36 months (mean,17.5 months).At 12 months followup,the values of ROM compared with that preoperative increased with significant difference,49.13° ±3.47° at volar flexion,47.13°±2.39° at dorsal extension,19.33°±3.29° at radial deviation,25.17°±4.89° at ulnar deviation,75.73°±7.66° at pronation,and 77.22°±4.89° at supination.According to Green-O'Brien standard,the results were excellent in 21 case,good in 17 cases and fair in 3 case,with 93％ excellent and good rate.Conclusion Wrist arthroscopy dose not only contribute to the diagnosis in ulnar impingement syndrome but also can be used in treating inflammatory synovium and cartilage lesions,bone drilling decompression,TFC repair and arthroscopic distal ulna resection with improvement in the range of motion of the wrist joint and function.

Objective To explore the mechanism and characteristics of MRI of acute patellofemoral joint impingement syndrome as well as its arthroscopic diagnosis and treatment.Methods There were a total of 46 cases (9 males and 37 females)with acute patellofemoral joint impingement syndrome from September 2005 to October 2012 in our department,and their average age was 21.6 years old (ranging from 15 to 31 years old).The Q angle,lateral patellofemoral angle (LPA) and lateral shift distance (LSD) of all cases were measured by X-ray and MRI preoperatively.MRI checked the medial patellar retinaculum injury by 4 degrees:15 cases of degree Ⅰ,18 cases of degree Ⅱ,8 cases of degree Ⅲ,and 5 cases of degree Ⅳ.All operations were monitored under arthroscopy.Firstly,the hemarthrosis was cleared,and secondly arthroscopy was used to explore all around inside joints,the free cartilage and osteochondral fragment were taken out,and the impaired surface of cartilage was repaired.Medial patellar retinaculum was treated arthroscopically with radio frequency ablation in degree Ⅰ injury.Lateral patellar retinaculum was released when the time of injury was longer than 2 weeks (9 cases),and medial capsule and retinaculum structure were reefed with modified arthroscopy assistance for patients with medial patellar retinaculum injury of degree Ⅱ to Ⅲ with obvious patellar shift.The medial capsule and retinaculum structure were strengthened by open surgical method for patients with degree Ⅳ injury.Results Constant findings under arthroscopy were haemarthrosis (46 cases),chondral lesions involved in the lateral femoral condyle and medial marginal of patella (37 cases),osteochondral fragments (28 cases),and tear of the medical retinaculum (46 cases).All patients were available at follow-up,the average duration of follow-up was 18.2 months (ranging from 12-36 months).No infection,nerve and blood vessel injury,redislocation or other complications happened.Lysholm,Tegner and AAOS scores were used both preoperatively and postoperatively,and LPA and LSD were compared.Statistically,the difference between these two scores was significant (P＜0.05).The sport ability was improved among all patients.Conclusion Acute patellofemoral joint impingement syndrome can be treated effectively by modified suture of medial capsule and retinaculum structure combined with release of lateral retinaculum.The function of knee joint recovered well after operation with satisfactory objective and subjective effects.

Objective To investigate the effect of leucine-rich-repeat-containing G-protein-coupled receptor 5 (LGR5 )on the proliferation and drug resistance of HeLa cells and its possible mechanism.Methods LGR5 expression was interfered using shRNA,and LGR5 knockdown HeLa cells were constructed.The effect of LGR5 on the proliferation and drug resistance of HeLa cell was evaluated by cell count,clone formation and MTT;the expressions of LGR5 and β-catenin in HeLa cells were detected by Western blot method.Results LGR5 knockdown HeLa cell line was successfully constructed;the cell growth rate and clone formation rate in shLGR5 group were markedly decreased compared to those in shCon group (P<0 .01 ).Drug resistance of HeLa to cisplatin differed significantly between shLGR5 group and shCon group (P<0.01 ).Moreover,the LGR5 knockdown inhibited the expression ofβ-catenin in HeLa cells.Conclusion LGR5 plays an important role in cell proliferation and drug resistance of HeLa cells,and its mechanism is related to Wnt/β-catenin signaling pathway.

Histone acetyltransferases (HATs) are involved in the regulation of gene transcription in eukaryotic cells and their inhibitors could be a promising class of drugs due to their ability to modulate transcription and exert antiviral, anti-inflammatory as well as antioxidant effects. Nonradioactive spectrophotometric HAT assay is an alternative method to the widespread radioactive assay but suffers from drawbacks as lack of sensitivity and accuracy. A simple, non-radioactive fluorescent assay that measures the production of CoASH was established by its facile reaction with O-phthalaldehyde and 2-amino-ethanol. This method gives much higher accuracy compared to spectrophotometric assay, and allows screening of various compounds with potential HAT inhibition. The novel assay should be a valuable tool in transcriptional research and especially drug discovery.

Objective The changes of thyroid hormone and cyclic nucleotides levels in rats with spleen-kidney deficiency syndrome were observed to evaluate the preventive and therapeutic effect of Yougui Wan(YW) for spleen-kidney deficiency syndrome,and to explore the relationship between the spleen and the kidney at microscopic level.Methods Male SD rats were randomly divided into normal control group,model group,and YW group.Rat models of spleen-kidney deficiency syndrome were established by gavage firstly with rhubarb(4g for each rat) decoction and then with hydrocortisone(25 mg?kg-1?d-1,im).The model group and YW group were treated with distilled water and YW(5.8 g?kg-1?d-1) respectively.The general status of rats was observed,and the plasma cyclic adenosine monophosphate(cAMP) and cyclic guanosine monophosphate(cGMP) levels as well as serum thyroid hormones(T3,T4 and rT3) and thyroid-stimulating hormone(TSH) contents were determined in all rats by radioimmunoassay(RIA).Results Compared with the normal control group,the serum contents of T3,T4,rT3 were decreased significantly(P
