ObjectiveTo design a new operation approach:extreme lateral transforaminal lumbar interbody fusion (E-TLIF) via digital technology and to discuss its feasibility in treatment of degenerative lumbar diseases.MethodsCT scan image data of lumbar vertebra were obtained from volunteer (a healthy male of 26 years old,67 kg in weight and 172 cm in height).Mimics was used to read and reconstruct the data into 3D images.We observe the anatomical bone structures of intervertebral foramen and nerve roots through CT scan and 3D reconstruction in Mimics to analysis the feature of this area.Then E-TLIF operation,pedicle screw insertion and cage placement were simulated by computer via digital technology in Mimics.The feasibility of this new approach was proved through operating on lumbar of formalin doused body with E-TLIF approach.ResultsAn incision of 9 cm lateral form the central line and 45° from the sagittal plane is operated to fully expose the foraminal area.Remove superior facet while save inferior facet is feasible with this approach in E-TLIF.There is enough room for fully revealing and excision of intervertebral disc,and cage placement through enlarged foraminal area.Digital technology is a more economic,efficient way to design a new operation approach.The results are in accord with the formalin doused body test.ConclusionMimics is an effectively,reliable and economic method to design an operation approach.And the result suggested that E-TLIF is a safe,less minimal invasive and more efficient operation approach in treatment of degenerative lumbar diseases.

Objective To evaluate the functional outcome after repair of zone V flexor tendon and to identify the relevant factors affecting the outcome.Methods A total of 52 patients ( 163 fingers) with wrist lacerations involving zone V flexor tendon from September 2003 to July 2009 were retrospectively studied.The average follow-up period was 32 months.The lacerated tendons were repaired by using three suture methods of different strands.Functional outcome was assessed by determining the active range of motion (AROM),and grip and pinch strength of the injured fingers,testing the independent flexor digitorum superficialis (FDS) action and employing the disability of arm,shoulder,and hand (DASH) questionnaire.Influencing factors for function of the repaired tendon including laceration section levels,repair methods,surgeons' experience,and injury severity were analyzed statistically.Results Functionally,146 out of 163 fingers (89.6％) achieved excellent or good range of motion and 103 out of 147 fingers with FDS injury (70.1％ ) obtained independent FDS action.Grip and pinch strength recovered to about two-thirds of the uninjured level.The mean DASH score was 11.9.Patients had adverse functional outcorme in tendons repaired with the 2-strand Kessler,in the tendons repaired by the surgeons with low level of expertise,or in the wrists with Spaghetti injuries,but levels of laceration section had no significant influence on the outcomes.ConclusionsFunctional recovery of zone V flexor tendon injuries is generally good,but repair methods,levels of expertise of surgeons,and injury severity have significant influences on the outcome.Thereby,advanced levels of expertise of surgeons can effectively improve the postoperative function.

Objective To explore the content change of Alpha Fetal Protein(AFP) and Alpha Fetal Protein Variants(AFP-L3) pre-and post-liver transplantation operation for liver cancer patients.Methods AFP-L3 was de-termined by micro centrifugal column from twelve cases of successive sera(For each case,one original shale pre-oper-ation,and mole shares post-operation successively),and preserved from patients who were diagnosed as fiver cancer and completed fiver transplantation operation.simultaneously the content of AFP and AFP-L3 in the original serum were also determined.and the ratio of AFP-L3 in AFP was calculated in order to compare the content change of AFP and the ratio of AFP-L3 pre-and post-liver transplantation operation.Results Compared with twelve cases of pre-and post-operation,the AFP in only five cases turned tO negative;The AFP in other cases keeped positive though AFP-L3%tumde to negative.and the content of AFP in some specific cases still keeped in a high level.Regarding AFP-L3,besides two casses turning to negative immediately after operation,the content of AFP-L3 in other patients de-creased gradually after operation,and it approached to negative(AFP-L3%<10%).Through statistical analysis,be-tween the half lives of AFP and AFP-L3%,there waa no statistic significance.Therefore,AFP-L3% could be considered as an independent reference item.Conclusion After a radical cure of liver resection or liver transplantation operation,AFP-L3%usually turned to negative in a rather short period (about 1 to 20 days).The ratio of AFP-L3 in AFP became be-low 10%,and it indicated that the operation would be quite complete,remaining liver would have hepatitis or hepatocirrho-sis.Otherwise,the ratio was not decrease during a long period,and it indicated the operation had not eliminated focuses completdy.

Background Research showed that transforming growth factor-β2 (TGF-β2) promotes scar formation.But its mechanism in scarring after glaucoma filtration surgery is worthy of studying.Objective This study was to investigate the effect of TGF-β2 on myofibroblast transition of human Tenon fibroblasts (HTFs) and scarring after glaucoma filtration surgery.Methods Tenon capsular tissue was obtained from 3 patients with strabismus during the surgery and was incubated in DMEM with 10％ fetal bovine serum (FBS).The cells were collected and passaged in the free-serum medium for 24 hours,and then 1,2,5,10,20 μg/L TGF-β2 was added into the medium respectively,to induce the transformation of HTFs,and 2 μg/L or 5 μg/L TGF-β2 was used to treat the HTFs for 6,24,48 and 72 hours.The control group was not treated with TGF-β2.The expressions of α-smooth muscle actin (α-SMA) and phosphorylation of the signaling proteins (pSmad2) in HTFs were detected by Western blot assay.The expressions of α-SMA and F-actin were located by cell immunofluorescine technique under the confocal immunofluorescence microscopy.Cell contractility was determined by collagen gel contraction assays.This study was approved by Ethic Committee of Institute of Surgery Research of Daping Hospital,and informed consent was obtained from each patient or custodian initial of the study.Results The expression of α-SMA protein in the HTFs was increased significantly after the treatment of TGF-β2 in comparison with the control group and reached a peak at 24-48 hours.The α-SMA expression was gradually weakened in the 10 μg/L TGF-β2 groups.Little of α-SMA and F-actin were expressed in the control group.However,strong staining for α-SMA and F-actin were observed in the 1,2 and 5 μg/L TGF-β2 groups and then the staining weakened at the concentration of 10 μg/L.In addition,pSmad2 showed a stronger expression in the 2 μg/L TGF-β2 group than that in the PBS group and FBS group,with the strongest expression in 30 minutes through 2 hours.The untreated gel contracted (78.00±3.13)％ from its initial size,and contraction in the 1,2,5,10 μg/L TGF-β2 group were (63.88±1.78)％,(20.69±0.65)％,(19.49-±0.54)％,(16.24±0.84) ％,respectively,TGF-β2 increased HTFs contraction significantly (Fgroup =859.400,P =0.000).Conclusions TGF-β2 can induce transdifferentiation of Tenon fibroblast into myofibroblast and increase cell contractility,with a concentration-dependent and time-dependent pattern to an extent.It may be the mechanism of scar formation after glaucoma filter surgery.

Objective To investigate the efficacy and safety of fluid resuscitation with 75 g/L NaCl solution in traumatic hypovolemic shock using Meta-analysis. Methods Based on the inclusion criteria,the randomized controlled trials (RCTs) were identified by retrieving the databases including PUBMED,EMBASE,OVID,Cochrane library and EBSCO.The quality of studies was also evaluated.Indices including systolic blood pressure,hemoglobin,serum Na level and mortality were extracted from the enrolled RTCs and were comparatively analyzed between the 75 g/L NaCl group and the isotonic saline group for evaluating the safety and efficacy of 75 g/L NaCI solution.The extracted data were analyzed by using the Review Manager 5.0.25. Results Six RCTs were eligible for Meta-analysis.The 75 g/L NaCl group displayed remarkable increase in systolic blood pressure and decrease in hemoglobin level,compared with the isotonic saline group ( MD =6.23,95％ CI 2.78-9.69,P ＜ 0.01 ; MD =-6.11,95％CI -8.25-3.96,P ＜ 0.01,respectively).Short-term hyperosmolar state in 75 g/L NaCl group was increased significantly but was considered acceptable ( MD =7.97,95％ CI 7.55-8.38,P ＜ 0.01 ).No significant difference in mortality was found between 75 g/L NaCl group and isotonic saline group ( RR =0.96,95％ CI 0.84-1.10,P ＞ 0.05). Conclusion Fluid resuscitation with 75 g/L NaCl solution is safe and effective for traumatic hypovolemic shock.

Objective To explore a suitable method to estimate the quantity of removing skin in double-fold eyelid operation.Methods Upper eyelid skin gently pulled towards eyebrows was flattened with the eyelash being slightly curved,the double-fold eyelid line that was parallelled to blepharitis was marked at 6-7 mm far from blepharitis.Then opening eyelid and looking upwards,the suprapalpebral fold was formed,and several dots were marked on the fold margin. After slightly closing eyelid the suprapalpebral fold margin line was formed through connecting the dots.The skin between the two line was the quantity to remove in operation.If the two line overlaped,removing skin did not need.Results A total of 89 cases were enrolled in this study.The patients were followed up from three months to one year,and the results showed that 67 cases were satisfactory,22 cases were basically satisfatory,and no one was not satisfactory.Conclusions The designing method for removing skin according to double-fold eyelid line and suprapalpebral fold margin line is a good method to estimate the quantity of removing skin in double-fold eyelid operation.

To developing a simple, rapid and sensitive immunoaffinity method for extracting DNA before amplification by the polymerase chain reaction(PCR). Using monoclonal anti-DNA bound to colloidal-gold beads(which called immunocolloidal-gold ) and extracting DNA from the specimen before amplification by PCR. The immunoaffinity method we use is extremely efficient in extracting DNA at low concentration, also, the beads carrying the DNA/anti-DNA complexes can be added directly to a PCR mixture without elution, and the presence of PCR inhibitors in specimens has no effect on amplification. When applied to serial dilution bacteria suspension, the detection of limit can be 100 CFU/mL, and the sensitivity of detecting artificial soil sample and milk sample were 101 and 100 CFU/mL. The immunoaffinity method described here can sever as a sensitive and practicable method for extracting DNA , particularly where samples have low concentrations of DNA or where the material is in poor condition.
