Objective To investigate the effect and safety of a low-dosed urokinase combined with fosinopri plus leflunomide and prednisone on treatment of moderate and severe IgA nephropathy (IgAN).Methods Fifty-seven patients with IgAN confirmed by biopsy combining with clinical presentations were enrolled,with their ages ranged from 15 to 55,proteinuria excretion ≥ 1.0 g/24 h,serum creatinine (SCr) ≤ 265.20 μmol/L,grade Ⅲ or above in Hass histologic grading systems for renal biopsy.The patients were randomly divided into trial group( n =28 ) and control group( n =29 ) and received treatment for six months.The patients in trial group were treated with a low-dosed urokinase combined with fosinopri plus leflunomide and prednisone,while those in control group were treated with prednisone and fosinopril.Results ( 1 ) After 6 months of treatment,the rates of complete remission (CR) and partial remission (PR) were 52.0％ and 40.0％ respectively in trial group,and 20.8％ and 54.2％ respectively in control group.The total remission rate(TR)and CR in trial group were significantly higher than those in control group ( TR x2 =0.47,P ＜ 0.05 ; CR x2 =5.11,P ＜ 0.05 ).( 2 ) The SCr level was decreased in trial group ( [ 115.83 ± 16.78 ] μmol/L v.s.(93.29 ±12.41 ) μmol/L,P ＜ 0.05 ),while increased in control group ( [ 112.79 ± 12.79 ] μmol/L v.s.( 136.99 ±25.97 )μmol/L,P ＜ 0.05 ).The two groups had significant difference on SCr clearance rate after treatment( P ＜0.05).There was no significant difference between the two groups on the endogenous creatinine clearance rate (Ccr) ( P =0.52 ),and no significant difference within trial group ( [ 79.34 ± 6.09 ] ml/min v.s.[ 85.12 ±12.26] ml/min,P =0.05)and within control group( [80.18 ±6.51 ] mi/min v.s.[84.22 ±8.39] ml/min,P =0.67 ).The levels of 24-hour proteinuria excretion after 6 months were decreased in both groups ( trial group:[1.93 ±0.55]g/24 hv.s.[0.78 ±0.42]g/24 h,P＜0.05;control group:[1.85 ±0.51]g/24 h v.s.[1.30±0.35 ] g/24 h,P ＜ 0.05 ),and the treatment effect was better in trial group ( P =0.04 ).Conclusion Treatment of moderate and severe IgA nephropathy with low-dosed urokinase combined with fosinopri plus leflunomide and prednisone is effective and safe by improving renal function and decreasing proteinuria.

Objective To investigate the incidence and influencing factors of aldosterone escape in patients with non-diabetic nephropathy by RASI-therapy. Methods A total of 104 patients with non-diabetic nephropathy were treated with ARB or combination therapy of ACEI and ARB in a mean follow-up period of 12 months. Aldosterone escape was determined according to the change of plasma aldosterone concentration before and after treatment during 6-month and 12-month ACEI/ARB treatment, while the influencing factors of aldosterone escape in patients with non-diabetic nephropathy was also analyzed after therapy with RASI . Results In 12 months, the incidence of aldosterone escape was significantly higher than that in 6 months (26.92% vs. 14.42%, P = 0.007). After 12-month treatment, the difference was statistically significant in incidence of aldosterone escape among different stages of CKD (P = 0.027). Compared with 6-month incidence of aldosterone escape in the losartan group, 12-month incidence increased evidently (P = 0.020). The Ald level was positively correlated with urinary protein excretion and the Scr level (r = 0.431, P = 0.003 and r = 0.336, P = 0.009, respectively), and negetively correlated with levels of the eGFR (r = -0.275, P = 0.006). Univariate Logistic regression demonstrated that risk factors of aldosterone escape included pre-treatment values of the urinary protein excretion (OR = 3.671, P = 0.028) and the eGFR (OR = 0.972, P = 0.019). Multivariate Logistic model revealed pre-treatment values of the eGFR was positively associated with aldosterone escape (OR = 0.970, P = 0.012). Conclusion The incidence of the aldosterone escape increases along with the time of treatment. Renal function has correlated with aldosterone escape and pre-treatment value of the eGFR is an independent risk factor of aldosterone escape.

BACKGROUND: In China, although microscope-assisted anterior cervical decompression has been performed by many spine surgeons in recent years, the application of microscope still needs to be further promoted in China. Therefore, it is necessary to systematically evaluate and analyze the clinical efficacy of cervical spondylopathy by comparing patients under microscope-assisted anterior cervical approach to traditional anterior cervical approach. As a result, it can provide the evidence for clinical decision in these cervical spondylopathy patients. OBJECTIVE: To systematically evaluate the effect between microscope-assisted anterior cervical approach and traditional anterior cervical approach in cervical spondylopathy patients. METHODS: Databases such as Medline, Embase, PubMed, Web of science, CBM, Wangfang databases, VIP, and CNKI were searched from inception to July 2019 to find literature related to microscope-assisted anterior cervical approach and traditional anterior cervical approach in treatment of cervical spondylopathy. Two investigators evaluated the researches independently and compared the operative time, intraoperative blood loss, the preoperative and postoperative Japanese Orthopedic Association score, neurological success rate, the preoperative and the postoperative visual analogue scale score, and the complication rates between two groups. The quality of the included literature was evaluated by the modified Jadad scale, the modified Newcastle Ottawa score and the methodological index for non-randomized-studies. The correlative clinical outcome in inclusive research was analyzed systematically by using Stata 12.0 Software. RESULTS AND CONCLUSION: (1) Twelve studies were accorded with the inclusion criteria, containing 892 cases (438 cases in the microscope-assisted group, while 454 cases in the traditional group). (2) There were no significant differences in the preoperative Japanese Orthopedic Association score (WMD=-0.100, 95%C/(-0.459, 0.259), P=0.585), operative time (WMD=6.852, 95%C/(-0.446, 14.149), P=0.066), the preoperative and postoperative visual analogue scale score (WMD=0.293, 95%C/(-0.023, 0.608), P=0.069; WMD=-0.T\8, 95%C/(-1.495, 0.059), P=0.070) between two groups. (3) Postoperative Japanese Orthopedic Association score (WMD= 1.310, 95%C/(0.621, P < 0.001), the rate of neurological success (WMD-4.639, 95%C/(0.294, 8.984), P=0.036) in the microscope-assisted group were higher than those in the traditional group. The intraoperative blood loss (l/MMD=-18.068, 95%C/(-24.504, -11.632), P< 0.001) and the rate of complication (RR=1.068, 95%C/(1.012,1.126), P=0.002) in the microscope-assisted group were significantly lower than those in the traditional group. (4) Performing anterior cervical approach under microscope has a better clinical effect than using traditional anterior cervical approach in the treatment of cervical spondylopathy, but more high-quality clinical studies are needed to verify it.

A PP plastic film for food packaging (0. 1 mm) was prepared by adding two antioxidants of 2,6-di-tert-butyl-4-methyl-phenol(BHT) and pentaerythritol tetrakis ( 3-( 3, 5-di-tert-butyl-4-hydroxyphenyl ) propionate)(Irganox 1010) with different concentrations into polypropylene (PP) resin, then mixing extrusion granulate by the double screw plastic extruder and hot pressing the film at 190℃. The migration amount of the two antioxidants in food simulants (95% ethanol) was determined by high performance liquid chromatography (HPLC) with diode array detector (PDA) (detection wavelength is 282 nm). The migration of BHT was detected and Irganox 1010 was not detected. Based on the large amount of experimental data, the migration model was fitted by a software, then the migration model of antioxidant BHT was established, the applicability of the two migration model was compared with the actual data. The results showed that the fitting degree ( R2 ) of Weibull model to the actual migration result was greater than 0. 99 and better than Piringer model. It was found that there was a mathematical relationship as τ≈12. 2 ( L2/D) between parameters of Weibull model and Piringer model.

Objective To report the clinical effect of repair of significant tongue defect after tongue cancer radical resection using anterolateral thigh perforator free flap with CTA three-dimensional reconstruction technique assistance.Methods From January,2012 to November,2015,13 cases were performed using anterolateral thigh perforator free flap in the repair of significant tongue defect after tongue cancer radical resection.Preoperation CT scan of the free flap donor site was done to obtain the three-dimensional images of arterial blood area by Digital Three-dimensional Reconstruction CT Technique to determine the origin of the anterolateral thigh flaps,direction,classification,length,diameter and the position of pedicle perforator.According to the condition of the defect of the tongue,flap of area from10 cm×9 cm to 8 cm×6 cm was design,the flap arteries and veins were anastomosed with the external maxillary artery or the superior thyroid artery,anterior vein,internal jugular vein or external jugular vein respectively.The shape and recovery of function of the reconstructed tongue were observed regularly after operation.Results All the flaps in the 13 cases survived,in the postoperative 4 to 18 months followed up,the appearance of the reconstructed tongue was close to the normal one,the patients were satisfied with the mastication and feeding function.Conclusion CTA three-dimensional reconstruction technique assisted anterolateral thigh perforator free flap technique is useful in obtaining good clinical effect,and it is one of the most best methods for repairing significant tongue defect after tongue cancer radical resection.

Objective To explore the clinical value of applying digital technology to make the course of toe vein clear before toe free flap transplantation for thumb reconstruction.Methods Before operation,scan the donor and recipient site by CT,and apply digital three-dimensional CT angiography reconstruction technology to got threedimensional images of the arteries and veins in the donor site for 22 various defected thumbs which were going to have toe free flap transplantation operation,thus indentifyed the types of FDMA and the distribution and course of the toe vein from June,2012 to March,2013.Used computer assisted anatomical modeling to analyze three-dimensional images of blood supply of the donor site and degree of defect of the recipient site and guide the operative design in the donor site according to the digital three-dimensional reconstruction technology.Conducted toe free flap transplantation for thumb reconstruction in accordance with the design.Results It shows that 64-slice dual-source spiral CT could well display the size,distribution and course of toe vein.The toe veins were clarified to two groups,deep one and superficial one whose diameter was larger and was the main reflux vein of the toe.Dorsal vein of the toe origind from venous plexus in the nail bed and it travels along the back of the toe to reach to the near side of metatarsophalangeal joint.And then it beeomes three to four dorsal metatarsal veins to infused dorsal venous arch of foot.The rule of its course was:centralize-decentralize-connect-decentralize again.The great saphenous vein origins from the inner side of dorsal venous arch of foot,rises along the crus before malleolus medialis and collect three larger tributaries:medial malleolar branches-anterior crural branch-outside crural branch.The small saphenous vein derives from the outside of dorsal venous arch of foot and winds behind lateral malleolus up to the back of the curs and infuses to the vein.Conclusion It is useful for venous return,reducing the incidence of vascular crisis by applying toe flap to reconstruct thumbs and clarifying the course and distribution of toe vein with the aid of digital three-dimensional technology to design operation,thus improving the survival rate of toe flap transplantation.
