Postoperative epidural adhesion is one of the most common causes of failed back surgery syndrome (FBSS), which can lead to back and leg pain or neurological deficit. Prevention of epidural adhesion after laminectomy is critical for improving the outcomes of lumbar surgery. The main origins of epidural fibrosis are raw surface of erector muscles and rupture fibers of intervertebral disc. The main current preventive methods for epidural adhesion include the usage of implants, chemicals and low dose radiation. However, most of them are still in experiment period. There are still controversies on the clinic usage of autograft free fat, ADCON-L, and Mitomycin C (MMC). The optimal implants are characteristics of better biocompatibility, degradable absorption and capability of existing for a certain period in body. The optimal medicine should have good effect on anti-desmoplasia, less side effects and long half-life. Besides, the combination of biodegradable medical film and drug and the mixture of two or more medical films are also the research frontlines of epidural adhesion. Further researches are required to explore new materials and drugs with stable and most favorable effect in preventing epidural adhesion.

AIM:To perform a new method for orbital implant and contracted socket through one time and its results. ·METHODS:Totally 114 patients 114 eyes, from January 2008 to June 2014, with contracted socket participated in this study. We incised the bulbar conjunctiva horizontally and excised scar tissue, then implanted the hydroxyapatite in the four extraocular muscles and tightly sutured the Tenon ' capsule. After that, we put the superior and inferior conjunctival petals backwards and sutured them to the Tenon ' s capsule. All the patients were divided into four groups according to the vertical diameter length of the conjunctival defect area:GroupⅠ:≤5mm; Group Ⅱ: 6-10mm; Group Ⅲ: 11-15mm; and Group Ⅳ: ≥16mm. These patients were followed up for 6mo to 3y to observe the conjunctival sac shaping and growth of conjunctiva. ·RESULTS:There were 64 cases in GroupⅠ, 31 cases in Group Ⅱ, 16 cases in Group Ⅲ and 3 cases in Group Ⅳ. All patients ' conjunctival defect was covered by new conjunctiva and scar tissue 4 to 6wk after surgeries. Ten cases had contracted socket; 2 cases had orbital implant exposure, requiring reoperation. Of the 114 cases, 8 had contracted socket and could use a smaller conformer, 106 could use a normal size conformer. ·CONCLUSION: When the conjunctival defect was ≤15mm, this new method can address the orbital implant and contracted socket at the same time. While it was ≥16mm, flap transplantation is necessary.

Objective To study the antitumor effect of toremifene on MCF7 cell lines,and investigate the role of mitogen-activated protein kinase pathway. Methods Inhibitory effect of toremifene alone or combined with MEK inhibitor PD98059 on MCF7 cells was measured by SRB test,and that on phosphorylated ERK was detected by Western blotting.Results Toremifene exhibited a concentration-dependent inhibitory effect on the activity of MCF7 cells.Phosphorylated ERK was significantly inhibited by 5,10 and 20 mmol/L toremifene.Combined with PD98059,toremifene had a significantly enhanced cytotoxity effect,which exceeded that of application alone. Conclusion Mitogen-activated protein kinase pathway may play an important role in the antitumor effect of toremifene which is independent of estrogens.Combined with PD98059,the antitumor effect of toremifene can be reinforced,indicating a synergistic effect of these two drugs.

Objective To evaluate the short-term therapeutic effect and radiation reaction of stereotactic radiotherapy for early stage non-small cell lung cancer in the elderly patients. Methods Thirty-one patients with stage Ⅰ - Ⅱ non-small cell lung cancer were treated with stereotactic radiotherapy. Patients aged 70-88 years, median age 76; 21 were stage I patients, and 10 stage Ⅱ ; 14 patients had tumor

Objective:To observe the effect of electroacupuncture (EA) at Jiaji (EX-B 2) points plus hydro-acupuncture with sinomenine hydrochloride for low back pain caused by compression fractures in the elderly.Methods:Ninety-five elderly in-patients with low back pain caused by compression fractures were randomly divided into an observation group and an EA group according to the visit sequence.Both groups received the same basic treatment.In the EA group,48 cases were treated with EA at Jiaji (EX-B 2) points plus the basic therapy;47 cases in the observation group received the basic treatment plus EA and hydro-acupuncture with sinomenine hydroch｜oride at Jiaji (EX-B 2) points.The levels of osteoprotegerin (OPG) and interleukin-1β (IL-1β) in peripheral blood were measured by enzyme-linked immunosorbent assay (ELISA) before and at the 21st day of treatment in both groups.Oswestry disability index (ODI) and visual analog scale (VAS) scores were used to analyze the clinical efficacy.Results:After treatment,the OPG content in the observation group was higher with statistical significance compared with that before treatment in the observation group and after the treatment in the EA group,respectively (both P＜0.05);the content of IL-1β,ODI and VAS scores were lower than those before treatment in the observation group and after treatment in the EA group with statistical significances (all P＜0.05).Conclusion:The combination of EA and hydro-acupuncture with sinomenine hydrochloride at Jiaji (EX-B 2) points is effective for low back pain caused by compression fractures in the elderly,and is superior to EA at Jiaji (EX-B 2) points alone.

Proteins extracted from two varieties of Chinese roses leaves were separated by two- dimensional polyacrylamide gel electrophoresis (2-DE) with immobilized pH gradient (IPG). Many difference proteins were isolated with molecular weights ranging 10-30 kDa and pI5-6. Three proteins of high levels observed in a gel were excised and identified using peptide mass fingerprinting and MS-MS. A summary of the identified proteins and their putative functions are presented. They are identified as eIF-5A、LEA protein and Hsp17. 5. Functions of these proteins in plant tolerance to high temperature were discussed.

Herpes simplex virusⅠ(HSVⅠ) regulating the pathway of transcription and translation modify in host cell is a very systematic and complicate system. A clear understanding of the concrete mechanisms of infection will greatly help to comprehend the virus replication and the interaction with the host cell. By the analysis of 2-DE, the heterogeneous nuclear ribonucleoprotein H2 in human fetal liver cell represent distinction after the HSVⅠinfection.Utilization of Northern blot and Western blot technologies verified the expression of hnRNP H2 in different stage of virus infection is varied.

Objective To observe transient receptor potential melastatin 7-like (TRPMTL) expression changes post myocardial infarction (MI) in mouse cardiac fibroblast (CF).Methods TRPM7 expression and Ca2+ influx in CF from MI and control mice were quantified by mRNA RT-PCR and whole cell patch clamp technique.Results (1) TRPM7 expression was significantly upregulated post MI and Ca2+ influx of CF were significantly increased post MI [ (7.4 ± 0.7 ) pA/pF vs.( 16.2 ± 1.7) pA/pF, P < 0.01 ] and Ca2+ influx of CF increased 3-fold under lower pH condition; (2) These effects could be blocked by knock-out TRPM7 gene with SiRNA.conclusion TRPM7L upregulation post MI and under lower pH condition are responsible for increased Ca2+ influx in CF.
