Objective To explore the anatomy and the adjacent of the medial malleolus,the operative approach of soluting the tibial nerve in endoscopy and the significance of making use of it in operation. Methods The five cadaver feet were dissected,the tibial nerve and the fiber diaphragm in the middle of me- dial and lateral plantar tunnels in the ten cadaver feet were soluted in endoscopic.Results The operative approach was designed on the basis of the anatomy data (the three-portal approach:The perpendicular bisetor which was the medial malleolus pointed to the medial margin of tendon calcaneus insertion was 4.5cm;The midpoint of the medial malleolus pointed to the calcaneus tubercle;The midpoint of the calcaneus tubercle to the medial margin of the first metatarsophalangeal joint).It was succeed that soluted the tibial nerve and the fiber diaphragm in the middle of medial and lateral plantar tunnels.Conclusion The operative approach on the basis of the anatomy data is design,and testfy the feasibility of exploring curved tunnel in endoscopic.

Aim The effect and mechanism of human placental extract(HPE) on the lipoprotein-cholesterol metabolism, peroxidation and the function of platelet aggregation in hyperlipaemia rats were abserved.Methods Wistar rat with hyperlipaemia models were given each HPE 0.4 ml (100 g)-1?d-1 through lavage for 12 days.The serum levels of TG,TC,LDL-C,HDL-C and HDL2-C in its subgroup were measured.The activies of LPO and SOD in both blood and liver tissue were determined .The effect of HPE on lipidosis of liver were abserved by fat dyeing.The levels of 6-keto-PGF1?,TXB2 in plasma and maximum platelet aggregation rate were measured by ELASA. Result The levels of HDL-C and HDL2-C were increased (P

OBJECTIVETo observe the change of Th immunological gene in renal transplant recipients after the treatment of cyclosporine (CsA) and tacrolimus (FK506).

METHODSThe peripheral blood lymphacytes just before and 24 hours after CsA and FK506 treatment were isolated. The total RNA of them were reverse-transcripted and examined by real-time quantity PCR array. The results were analyzed by bioinformatic methods.

RESULTSThe TLR4, CEBPB, IL4R, IL1R1,IL18R1,and IL1R2 genes were remarkably upregulated, whereas IL-2, CCL5, CD27, CCR5, CCR4, CD4, RPL13A, TGFB3, CD86, CCR3, STAT1, NFATC2IP, IL23A, IL15, IRF4, and TFCP2 were downregulated 24 hours after CsA treatment. The IL18, IL7, PTPRC, TNFSF4, SPP1, GFI1, TLR4, IL13RA1, TNF, INHBA, LAG3, IL13, IL1R1, SOCS5, IL10, YY1, TBX21, FASLG, IL18R1, and IL1R2 genes were remarkably upregulated, whereas IL-2, IL-3, IL-4, IL-6,CCR5, CD4, CD27, CD40LG, IL15, CCR3, CD86, CCR4, and IRF4 were obviously downregulated 24 hours after FK506 treatment.

CONCLUSIONCsA and FK506 exert their therapeutic effectiveness by regulating the expressions of a series of target genes.

2cm~2.Conclusions The auto-cranial pedicle flap via endonasal repairing blow-out fractures of or- bital inferior wails is an effective technique.The results are good for improving eye movement especially for fracture ranged≤2cm~2. (Ophthalmol CHN,2007,16:388-390)

Bacillus subtilis B6-1 was used as an original strain for mutagenic treatment and a defined medium was used as the selective medium. A mutant named B. subtilis W003 was isolated after three serial ultraviolet (UV) irradiations and one diethyl sulfate (DES) treatment. The ?-PGA yield on a rotary shaker was enhanced from 10.9 g/L in parental strain to 20.5 g/L in the mutant. It was illustrated by single factor experiments that the optimal carbon and nitrogen sources were glucose and (NH4)2SO4 respectively. The optimal fermentation medium was achieved by orthogonal test. In the optimal medium, a ?-PGA yield of 45.3 g/L was obtained after 36 h cultivation.

Poly ?-glutamate is a biopolymer material that has a good application prospect.The Vitreoscilla hemoglobin(VHb) gene was integrated into the chromosome of Bacillus licheniformis WX-02 by integrative vector pDG1730-vgb.The expression of VHb was confirmed by CO-difference spectra analysis.It was shown by the results of batch cultures in a 3 L bioreactor that biomass and ?-PGA obtained in the recombinant M2 were 25.5 % and 20% higher than those of the control respectively.

Objective To evaluate the effectiveness of arthroscope-assisted surgical technique in treating knee fractures and knee peripheral fractures.Methods From September 2000 to December 2005,there were 46 cases with knee or knee peripheral fractures,in whom artbroseope-assisted surgical technique was performed in 36 cases including 24 males and 12 females,with mean age of 30.5 years (18-52 years).Of 36 cases,26 cases with patella fractures were treated by internal fixation of tension band using cancellous bone screws,four with distal end femoral fractures by retrograde interlocking using intramedullary nail and six with fractures of tibial plateau and tibial condyle crista by internal fixation u- sing cancellous bone screws.Results The mean hospitalization was eight days.A follow up for 3-36 months(average 14 months)in 36 cases showed fracture healing.Of 36 cases,32 cases regained full knee range of motion,four left with terminal flexion,with mean loss of 15?,and had thigh circumference (10 cm above knee)1.1 cm(range 0.6-2.0 cm)shorter than health side and two had slight pain in the knee joint.Lysholm knee joint function score was 86.5+7.6 for patellar fractures,tibial plateau frac- tures and condylar crista fractures.Conclusion As for knee or knee peripheral fractures,arthroscope- assisted surgical technique can provide fine monitoring,decrease trauma and complications,fixate inter- nally and help early ground exercise.

·AIM: To improve our understanding of retinoschisis at the macular area.·METHODS: From January 2003 to January 2005, the patients whose macular retinoschisis was confirmed by optical coherence tomography (OCT) were included in the study. Their data and other results were further analyzed.·RESULTS: During that period, macular retinoschisis was found in 116 eyes which fit the including criteria. Among these, 94 eyes were pathological myopia; 17 were X-linked congenital retinoschisis; and 5 had excavation of optic disk.By analyzing the OCT figures, it was found that retinoschisis could happen at many locations within retinal neural epithelium, including inner, middle and outer part. The retinoschisis caused by different reasons differs in OCT results.·CONCLUSION: Retinoschisis at the macular area was not rare at the clinic, and the retinoschisis may be located at different parts of the retina. OCT was useful in the diagnosis and follow-up of macular retinoschisis.
