AlM: To study the trabeculectomy clinical effect of use tunnel knife to make double - deck scleral flap and to cut off the layer scleral flap of glaucoma.METHODS: Using the random grouping method to divide 46 cases (60 eyes) of glaucoma into the treatment group of 24 cases (32 eyes) and control group of 22 cases (28 eyes). The treatment group, tunnel knife was used to make double- deck sclera flap and superficial scleral flap about the size of 5mm×5. 5mm, 1/3 scleral thickness, under the sclera flap made another one about the size of 3. 5mm× 4mm, 1/3 scleral thickness, resected the middle layer of the sclera flap, removed 2mm×2mm trabecular tissue, underwent routine peripheral iridectomy, could adjust suture the superficial scleral flap, sutured Ball fascia and bulbar conjunctiva. ln control group, routine glaucoma trabeculectomy was undergone.RESULTS:Patients were followed up for 1a, the vision in treatment group was obviously better than that in the control group, with a statistically significant difference (P< 0. 05). The postoperative intraocular pressure of the two groups of patients were significantly lower than that of the preoperative one. Postoperative 1 and 3mo, no statistical significant difference of intraocular pressure in two group(P>0. 05). But after 6 and 12mo, the intraocular pressure of the treatment group were significantly lower than that of the control group, with statistically significant difference (P<0. 05). Postopeartive 1a, the cumulative complete success rate and conditions for successful rate were 90. 63% and 96. 88% in the treatment group, and those were 75% and 89. 29% in control group. There was significant difference between two groups(P<0. 05).CONCLUSlON:The trabeculectomy have a good effect to lower the intraocular pressure by use tunnel knife to make double-deck scleral flap and to cut off the layer scleral flap. The scleral flap have uniform thickness, smooth surface, and the function of the filtering bleb maintained for a long time, less postoperative complications, suitable for various types of glaucoma, so it is worthy of clinical promotion.

Objective To investigate the expression of phosphatidylinositol 3-kinase(PI-3K)in adipose tissue of polycystic ovary syndrome patients(PCOS),and explore molecular mechanisms of insulin resistance(IR)in PCOS.Methods Samples from patients with PCOS with IR(n=19),PCOS without IR (n=10)and controls(n=15)were collected.Serum fasting insulin(FIN)and fasting plasma glucose (FPG)were measure& Insulin resistance index was calculated using homeostasis model assessment (HOMA)to analyze the relationship between these markers and IR.Western blot technique was used to detect the PI-3K p85 subunit.Gene expression of PI-3K p85 subunit was detected by reverse transcription polymerase chain reaction(RT-PCR)method.Kinase activity was detected by immunoprecipitation,thin- layer chromatography and gamma scintillation counting.Results(1)The levels of FIN[(25.2?3.8) mU/L]and HOMA-IR(1.6?0.3)in PCOS with IR were significantly higher than those in PCOS without IR[(13.4 +3.8)mU/L,0.9?0.3]and controls[(9.5 +2.6)mU/L,0.5?0.3;all P<0.05).(2) There was no significant difference in the protein(0.65?0.10)and gene expression(0.92?0.12)of PI-3 K p85 subunit in PCOS with IR compared with PCOS without IR(0.72?0.10,1.01?0.10)and control groups(0.73?0.14,1.00?0.12;P>0.05).(3)PI-3K activity in PCOS with IR(81%)and PCOS without IR(89%)was significantly decreased(P<0.01,P<0.05)and negatively correlated with HOMA- IR(r=-0.69,P<0.01;r=-0.62,P<0.05).Conclusions No significant difference in the protein and gene expression of PI-3K p85 subunit in PCOS with IR is found.The decreased PI-3K activity may lead to IR of PCOS.

Objective To explore the best way to diagnose and cure the nephrosis with ureteropelvic junction obstruction(UPJO) in children.Methods The diagnosis of 26 cases of nephrosis with UPJO were confirmed by ultrasonogram and IVU examinations.All patients underwent AndersonHynes procedures.These results were analyzed and summarized.Results All the diagnosis were proved to be correct by operation and pathology examinations,the operations were carried out successfully.Twenty-four cases were followed up for 6 months to 2 years.After the operation,the hematuria,urinary frequency,abdominal mass and distention disappeared,the urine analysis was normal,all cases cured clinically.Ultrasonogram examinations showed the thickness of parenchyma increased and the large kidneys lessened.Significantly improved renal fuoction on IVU examinations was observed in the 24 cases compared with that before the operations.The ureters of 20 cases displayed well.Conclusions The combination of ultrasonogram and IVU is very effective method to diagnose UPJO in children.Anderson-Hynes technique is the best procedure to cure the UPJO.

Objective To explore the effect and action principle of extracorpoporeal shock wave(ESW) combine hyperbaric oxygen(HBO) in bone nonunion treatment .Methods Totally 50 standard New Zealand white rabbits were chosen ,and 48 rabbits were successfully made to models .Then ,they were divided into four groups by using the random number table ,12 in each group . The group A was in ESW combine HBO group ;The group B was in hyperbaric oxygen group ;The group C was in pure ESW group ;The group D was in control group .X‐ray inspected before treatment and after treatment in 4 、8 、12 weeks .The calcium con‐tent was checked ,the osteoblast in bone callus was observed by the optical microscope ,and the data was analyzed by statistics .Re‐sults There was a significant difference in 4 ,8 ,12 weeks between group A and group B ,C ,D in the nonunion gap(P< 0 .05) ,there was significant difference in 4 ,8 ,12 weeks between group A and group B ,C ,D in the generation bone callus(P< 0 .05) .Callus calci‐um content of group A was higher than group C ,the difference was statistical significance(P< 0 .05) ,there was significant differ‐ence in 4 ,8 weeks between group A and group C in callus osteoblast count(P < 0 .05) .Conclusion ESW combine HBO treatment for bone nonunion is better than pure ESW therapy ,simple hyperbaric therapy has no obvious help for the treatment of bone nonun‐ion ,HBO can be used as a good synergy method in the extracorporeal shock wave treatment of bone nonunion .

Objective: To optimize preparation techniques for Herba E pimedii flavonoid phytosomes (EFP) and explore their suitable pharmaceutics. Methods: To optimize the preparation conditions by means of unifo rm design and step regression, prepare Herba Epimedii total flavonoid phytosomes by means of solvent evaporation and investigate the accumulative dissolution of different ratios of EFP-PVP precipitates by means of dissolution release. Resu lt: The optimized preparation conditions are as follows: solvent-tetrahydrofura n, lecithin to PVP-2.5 times, temperature-40 ℃ and reaction-3 hours. Oil/wa ter apparent partition coefficient of icariin was enhanced more than 4 times by phospholipid. The accumulative dissolution of Herba Epimedii flavonoids of EFP- PVP precipitate was significantly higher than that of its physical mixture and H erba Epimedii extract tablet. Conclusion: Phospholipid can ef fectively enhance the oil/water apparent partition coefficient of icariin, and P VP can improve the dissolution of Herba Epimedii phytocomes, but the pharmacokin etics needs further study.
