BackgroundWhether the peeling of the inner limiting membrane (ILMP) increase the closure rate of idiopathic macular hole is still in controversy.Some ophthalmologist recommend vitrectomy combined with inner limiting membrane peeling for the treatment of idiopathic macular hole.However,the removal of ILMP is difficult because of its similar appearance to adjacent tissues.Objective This study was to investigate the efficacy of triamcinolone acetonide(TA) and indocyanine green(ICG) double staining-assisted vitrectomy combined with ILM peeling during the surgery.Methods A consecutive case- observational study was designed.The standardized vitrectomy was performed in 25 eye of 23 cases with IMH.During the vitrectomy,TA and ICG were injected into posterior pole vitreous to visualize and assist the ILM peeling.The dying effectiveness was observed,and the closure rate of macular hole,visual acuity,intraocular pressure and complications were evaluated after surgery.Written informed consent was obtained from each patient prior to operation.Results Posterior vitreous cortex and ILM were visible and the residual vitreous and cortex were removed clearly after dying of TA and ICG in all the 25 eyes.During the following-up duration of 3-8 months,the completely anatomical reattachment of the macular area was in 22 eyes ( 88.0％ ) and partially reattachment in 3 eyes( 12.0％ ).The best corrected vision was 0.07-0.60 in all of the operated eyes 2 months after surgery.Conclusions TA and ICG- assisted vitrectomy combined with ILM peeling appears to be a safe and effective method for IMH repair.

Objective To construct the eukaryotic expression plasmids of short hairpin RNA (shRNA) specific for mouse Bcl-2-assoeiated athanogene 1 (BAG-1) and to observe their inhibitory effects on the expression of BAG-1 gene in mouse melanoma B16FI0 ceils. Methods Plasmids named pRNAT-U6.1/Neo-BAG-1, were designed and constructed to target the mouse BAG-1 mRNA coding region. LipofectaminTM 2000 was used to transfect plasmids into BI6F10 cells. Negative plasmid-transfected and tmtransfected B16F10 cells served as negative and blank controls respectively. Forty-eight hours following transfection, G418 was used to select the resistant cells. The mRNA and protein expression of BAG-1 gene was measured by reverse transcription-PCR and Western blot respectively about 1 month after the transfection. Results The eukaryotic expression plasmids, pRNAT-U6.1/Neo-BAG-1, were constructed, and verified by restriction enzyme digestion and DNA sequencing. The transfection rate in B16F10 cells was 20% -30%. Compared with the blank control, the mRNA and protein expression of BAG-1 in BI6FI0 cells was significantly inhibited by BAG-1 shRNA (both P<0.05), and the inhibition rates were (77±4)% and (62 ±2)%, respectively. Conclusions These results indicate that the eukaryotic expression vectors containing shRNA against BAG-1 gene, pRNAT-U6.1/Neo-BAG-1, are successfully constructed, and can significantly inhibit the expression of BAG-1 gene in mouse melanoma B16F10 cells.

Objective To explore the operative methods and clinical outcomes in emergency or sube- mergency repair for the complicated tissue defects in hand in first stage applying microsurgical technique. Methods From Jan.,2000 to Aug.,2005,49 emergency cases of complicated hand tissue defects were re- paired in the first stage with replantation,reconstruction,free flaps,combined finger reconstruction and flap transplantation,including 21 cases in mini tissue mass replantation or reconstruction,15 cases in replantation combined with free flap transplantation,8 cases in replantation and reconstruction combined with free flap transplantation,5 cases in combined multiple digits reconstruction with free flap transplantation.The free flap transplantation included the anterolateral femoral flap,the latissimus dorsi myocutaneous flap,the dorsalis pe- dis flap,the media pedis flap and the instep flap.Results All the flaps,the replanted and reconstruceted finger survived uneventfully except for one replanted finger necrosis.45 cases healed in the first stage and the other 4 cases healed in the second stage.During a follow-up from 6 months to 3 years postoperatively,a satis- factory appearance and function of the reconstructed hand was achieved.The excellent and good rate was 85.7% assessed with provisional functional assessment criterion for upper limbs issued by Chinese Society of Hand Surgery.Conclusion The emergency or subemergency repair for the complicated tissue defects in hand has the advantage of short-term treatment and desirable functional outcome.The emergency replantation and reconstruction combined with various flaps or tissue mass can be applied to repair tissue defect in hand in the first stage according to the position and area of the defect along with the technique level of the surgeon, having been proved to achieve desirable clinical outcomes.And the key points leading to a successful operation is the correct treatment for the raw surface of the defects,suitable choice for various flaps,logical design of combination pattern and prevention and timely treatment for vessel crisis.

Objective:To evaluate the effect and mechanism of davallia mariesil flavones (DMF) improving osteoporosis via Notch signaling pathway.Methods:(1) 120 cases patients with osteoporosis in our hospital from January 2016 to January 2017 were analyzed,and divided into experiment group (60 cases) and control group (60 cases) using digital random grouping method.Experiment group was treated with DMF combined with D-calfor.Control group was treated with D-calfor only.After treatment, the levels of serum calcium,serum phosphor,TNF-α,MCP-1 and IL-6 in serum were detected to evaluate the clinical efficacy.(2) Bone marrow stromal cells were separated and cultivate.NC group:DMEM(contain 10% FBS).RA group:RA(0.4 mmol/L).DMF+RA group:DMEM(contain DMF)+RA(0.4 mmol/L).Jaggedl+RA group:Jaggedl(1 000 μg/L)+RA(0.4 mmol/L).Jaggedl+DMF+RA group:Jaggedl(1 000 μg/L)+DMEM(contain DMF)+RA(0.4 mmol/L).DAPT+RA group:DAPT(16 μmol/L)+RA(0.4 mmol/L). DAPT+DMF+RA group:DAPT(16 μmol/L)+DMEM(contain DMF)+RA(0.4 mmol/L).Western blotting assays and PCR were performed to assess mRNA and protein levels of Notch-1,Hes-1.Results: (1) In clinical study,the effective rate in treatment group was obviously higher than control group (91.67%>76.67%,P<0.05).The levels of serum calcium and serum phosphor in the experiment group was higher than in the control group (P<0.05).The levels of TNF-α,MCP-1 and IL-6 in the experiment group was lower than in the control group (P<0.05).(2) In experimental study,compared with the RA group,the expressions of Notch-1,Hes-1 mRNA and protein were upregulated in Jaggedl+RA group,but were downregulated in DAPT+RA group,DMF+RA group (P<0.05). Compared with the Jaggedl+RA group,the expressions of Notch-1,Hes-1 mRNA and protein were downregulated in Jaggedl+DMF+RA group (P<0.05).Compared with the DAPT+RA group,the expressions of Notch-1,Hes-1 mRNA and protein were downregulated in DAPT+DMF+RA group (P<0.05).Conclusion:DMF could improve the condition of osteoporosis.The mechanism may be associated with inhibiting the Notch signaling pathway by DMF.

Objective To observe the effect of human immunoglobulin on elderly head and facial post herpetic neuralgia (PHN) and peripheral blood TNF-α.Methods One hundred and twenty-two inpatients with PHN aged ≥65 years old were selected and divided into the observation group (52 cases) and control group (70 cases) by the systematic sampling method.The control group was given the early conventional combined therapy,while on this basis the observation group was intravenously dripped by human immunoglobulin.The incidence rate of PHN and pain visual analog scale(VAS) score at 1,2,3 months after recovery discharge from hospital were recorded in the two groups.Other 20 healthy elderly people were selected as the healthy control group.The TNF-α level was determined in the two patients groups before and after treatment and in the healthy control group.Results The PHN occurrence rate at 1,2,3 months after discharge in the observation group was significantly lower than that in the control group(P＜0.05);the VAS score after treatment and at 1,2,3 months after discharge in the observation group was significantly lower than that in the control group (P＜0.05);serum TNF-α level after treatment in the observation group was significantly lower than that in the control group (P＜0.01),moreover which was close to the level in the healthy control group(P＞0.5).Conclusion Human immunoglobulin can reduce the PHN occurrence in the old people with head and facial herpes zoster and reduce the peripheral blood TNF-α level.

OBJECTIVETo study the evidence-based therapy of edema in nephrotic syndrome by analyzing the literatures systematically.

METHODSThe literatures related to the treatment of nephrotic edema were retrieved from the following: Chinese Biological Medicine Database (CBM-disk), Chinese Journals Full-text Database (CNKI, 1994-2006), Chinese Technological Periodicals Database (VIP, 1989-2006), Chinese Evidence Biological Medicine/Cochrane Central Database (CEBM/CCD), Cochrane Library Database, MEDLINE (1966-2006), EMBASE (1975-2006), MEDLARS, SCI (1985-2006) and OVID by electron and craft search with the following key words: nephrotic syndrome, edema, recalcitrant edema, refractory edema or resistant nephrotic edema, and treatment, diuretic therapy or human albumin treatment. The relevant literatures on randomized controlled trials (RCT) that met the criteria were statistically analyzed by the Coorporative network software RevMan 4.2.

RESULTSA total of 113 articles were searched (60 in Chinese and 53 in English), of which 12 were RCT. Three of the 12 articles were included for Meta analysis. Meta analysis showed that dextran-40 together with furosemide was effective for nephrotic edema. Human albumin solution could be used in nephrotic edema patients with coexistent severe hypoalbuminemia. A combination of diuretics by intravenous drip infusion was effective for diuretic-resistant nephrotic edema.

CONCLUSIONSThe treatment for nephrotic edema should be individualized. The evidence of treatment of nephrotic edema has not been fully elucidated. Further multicentre, large sample, and randomized controlled trials are needed.
