BACKGROUND: Hallux valgus is a common orthopedic disease, and its causes are complex and treatment is varied. The mechanical analysis of hallux valgus is an issue of concern. The finite element analysis makes it predictable to treat hallux valgus. OBJECTIVE: To explore the clinical application of finite element analysis in biomechanical study of hallux valgus.METHODS: The first author searched CNKI and PubMed databases from January 1980 to March 2017 using the key words of "finite element, hallux valgus" in English and Chinese, respectively. The repetitive, irrelevant and low-quality articles were excluded. Finally 33 eligible articles were included in accordance with the inclusion criteria, and the critical issues of finite element analysis applied in hallux valgus were reviewed. RESULTS AND CONCLUSION: (1) There are many researches concerning finite element of hallux valgus, which mostly require physicians to work with engineers. These methods are already very mature, but most of the model and material properties of the data come from foreign researches. (2) The finite element analysis is important and reliable for the etiology of hallux valgus, preoperative planning and prognosis. (3) The finite element model of the hallux valgus is only used on static analysis and gait cycle analysis, the modeling details and definition of material properties still need to be improved.

A case of adrenal ganglioneuroblastoma is presented here. This adrenal ganglioneuroblastoma was found in a 27-year-old female 7 months after delivery. CT clarified that the tumor originated retroperitoneally and was large in size (11.4 cm x 9.4 cm). The tumor was surgically removed together with pancreatic body and tail, left kidney and spleen, and pathological diagnosis was adrenal ganglioneuroblastoma-intermixed. Adrenal ganglioneuroblastoma is extremely rare in adults, with only about 9 cases documented including this case.

OBJECTIVETo develop a high-throughput screening assay for Farnesoid X receptor (FXR) agonists based on mammalian one-hybrid system (a chimera receptor gene system) for the purpose of identifying new lead compounds for dyslipidaemia drug from the chemical library.
METHODScDNA encoding the human FXR ligand binding domain (LBD) was amplified by RT-PCR from a human liver total mRNA and fused to the DNA binding domain (DBD) of yeast GAL4 of pBIND to construct a GAL4-FXR (LBD) chimera expression plasmid. Five copies of the GAL4 DNA binding site were synthesized and inserted into upstream of the SV40 promoter of pGL3-promoter vector to construct a reporter plasmid pG5-SV40 Luc. The assay was developed by transient co-transfection with pG5-SV40 Luc reporter plasmid and pBIND-FXR-LBD (189-472) chimera expression plasmid.
RESULTSAfter optimization, CDCA, a FXR natural agonist, could induce expression of the luciferase gene in a dose-dependent manner, and had a signal/noise ratio of 10 and Z' factor value of 0.65.
CONCLUSIONA stable and sensitive cell-based high-throughput screening model can be used in high-throughput screening for FXR agonists from the synthetic and natural compound library.

Acute graft-versus-host disease (GVHD) following liver transplantation is a rare but fatal complication. The correct diagnosis and management of GVHD after liver transplantation are still major challenges. Herein, we reported successful salvage treatment of acute GVHD by withdrawal of immunosuppression in a patient who presented with fever, skin rashes, and decreased blood cell counts after liver transplantation. This case highlights the need for awareness of drug-induced liver injury if liver function tests are elevated during treatment, especially in patients taking multiple potentially hepatotoxic drugs, such as broad-spectrum antibiotics. When occurs, an artificial liver support system is a useful tool to provide temporary support of liver function for the patient in the event of drug-induced liver injury.

OBJECTIVETo study the changes in sciatic nerve blood flow and the expression of collagen type I after electric injury of rabbit nerve with different voltages.
METHODSThirty-six healty rabbits were randomized into 3 groups before receiving injury with electricity in voltages, i.e. 50 v, 75 v, and 100 v groups. The changes in blood flow of sciatic nerve were observed with Laser Doppler Flowmeter immediately after injury and 1, 4, 8 weeks after injury. The changes in the expression of collagen type I was observed by immunohistochemical method, and the positive expression rate was calculated.
RESULTSThe sciatic nerve blood flow increased in all groups immediately after electric injury. In the 75 v and 100v groups, the nerve blood flow [(53 +/- 3 ), (48 +/- 5) PU] was obviously lower than that of normal value [(62 +/- 4) PU, P < 0.05]. There was little collagen type I deposition in 50 v group, while brown collagenous fibers in epineurium and perineurium were observed in 75 v and 100v groups 4 and 8 weeks after injury. The expression of collagen type I in all groups were obviously higher than that of normal value, and that in 75v and 100 v groups were higher than that in 50 v group at bachl time-point (P < 0.01).
CONCLUSIONThe restoration of sciatic nerve blood flow is postponed following by the injury with increase of the electrical voltage. The collagen deposition after electrical injury may be one of the reasons for nerve blood flow decrease.

OBJECTIVETo assess the clinical efficacy and safety of Shuxuetong injection against progressive ischaemic stroke.
METHODRandomized controlled trials (RCTs) and quasi randomized controlled trials (quasi-RCTs), which focused on treating patients with progressive ischaemic stroke using Shuxuetong injection were identified from Cochrane library, Medline, EMbase, CBM database, CNKI database, VIP database and Wanfang database. Data was extracted and evaluated with designed form. RevMan 5.1 software was used for data analysis.
RESULTEleven RCTs with 972 patients were included in this review. Only one research reported the mortality rate. None of the trials mentioned dependency of the patients during the follow-up period. The results of Meta analysis were listed as follows. Compared with normal treatment measures, total effective rate of 11 RCTs suggested that Shuxuetong were more effective with OR 4.46, 95% CI [3.02-6.59]. A greater difference in patients using Shuxuetong injection was found in 7 RCTs about the NDS with MD 5.86, 95% CI [4.80-6.93], compared with normal treatment measures. Researches with ADR/AE information of Shuxuetong injection showed that the symptoms of ADR/AE were moderate.
CONCLUSIONConclusions from this review may have a high risk of bias because of the low quality of the researches, hence it was not adequate to draw any reliable conclusions about the efficacy of Shuxuetong injection in progressive ischaemic stroke. More trials with high quality are required in the following researches.
