Objective To explore the clinical effect of ligament advanced reinforcement system ( LARS) artificial ligament reconstruc-tion of the anterior cruciate ligament ( ACL) in the operation. Methods Sixty patients with ACL injury in our hospital from September 2011 to May 2013 were randomly divided into LARS group and autologous hamstring tendon ( group ST/G) group with 30 cases in each group,the Lysholm score,IKDC score,the difference of clinical effect and bone tunnel of patients in two groups before treatment and at 3rd,6th,9th, 18th months after treatment were compared. Results The time of walking with crutch,ambulation and restore movement in LARS group were obviously shorter than those in ST/G group(P<0. 05). The Lysholm score,IKDC score,the difference of clinical effect and bone tunnel of patients in two groups after treatment were better than those before treatment(P<0. 05). The difference of Lysholm score and IKDC score be-tween two groups before operation was not significant (P>0. 05). The Lysholm score and IKDC score of LARS group at 3rd,6th,9th months after operation was higher than that of ST/G group,and at 18th months after operation,the difference of Lysholm score and IKDC score be-tween two groups was not significant (P>0. 05). At the last follow-up,the distribution effect of LARS group was higher than that of ST/G group (P<0. 05). The excellent and good rate of LARS group (93. 33%) was higher than that in ST/G group(76. 67%),but the difference was not significant (P>0. 05). There were 6 cases of patients with bone tunnel enlargement in LARS group,14 patients had bone tunnel en-largement in ST/G group. The bone tunnel enlargement rate was significantly higher than that of the LARS group (P<0. 05). Conclusion Ligament advanced reinforcement system of artificial ligament in anterior cruciate ligament reconstruction with autologous hamstring tendon re-construction can significantly speed up the recovery of the patients,and improve the postoperative curative effect and reduce the incidence of postoperative bone tunnel enlargement.

Objective To investigate the effect of curcumin on chronic pancreatitis in rat.Methods Eighteen one-month old male SD rats were randomly divided into control group,ANP group and curcumin group with 6 rats in each group.After fed by 25％ alcohol for twelve weeks,the rats in ANP group were intraperitoneally injected with lipopolysaccharides ( LPS,2 mg/kg body weight) once a week for 4 weeks.The rats in curcumin group were fed with curcumin when they were intraperitoneally injected with lipopolysaccharides.Seventeen weeks later,the rats were sacrificed.Serum glucose was measured,pancreatic morphology was routinely examined,collagen deposition was determined by Masson stain,and the amylase and lipase in pancreatic tissue were evaluated,TGF-β1 mRNA was determined by using RT-PCR.Results The pathological score of control group,ANP group and curcumin group was 1.17 ±0.41,7.33 ±2.58 and 3.50 ± 1.05,and the score in curcumin group was lower than that of ANP group (P ＜ 0.01 ),but which was higher than that in control group (P ＜ 0.05 ).There was no difference in the serum glucose among the groups.The levels of amylase and lipase in pancreatic tissue were (7348 ± 102 ),( 14135 ± 1272) U/g,which were significantly higher than those in ANP group[( 5428 ± 547 ) and (9123 ± 1250 ) U/g,P ＜ 0.05].The expressions of TGF β1 mRNA in control group,ANP group and curcumin group were 0.618 ± 0.019,0.818 ±0.012,0.745 ±0.088,and the values in ANP group were significantly higher than those in control group and curcumin group (P ＜ 0.01 ).Conclusions On the basis of long term ethanol intake,repeatedly intraperitoneal injection of LPS can induce chronic pancreatitis,and curcumin has anti-fibrosis effect possibly by its inhibitory effect on the expression of TGF-β1.

[Summary] This retrospective analysis showed that the level of apolipoprotein E was significantly higher in diabetic nephropathy group compared with normal albuminuria group [50.4 (40.8,65.9) vs 46.2 (38.6,56.8)mg/L,P＜0.01].Difference in urinary albumin to creatinine ratio (ACR) among the groups based on the tertile of apolipoprotein E were significant (P＜ 0.01).Multiple linear regression analysis demonstrated that apolipoprotein E was independently associated with ACR (β =0.14,P＜0.05).

Objective To assess the effect of rhein on diabetic nephropathy in rats with type 2 diabetes mellitus. Methods Diabetes was induced by high-lipids and high-sucrose diets (20% sucrose, 10% lard, 2.5% cholesterol, 1% cholic acid and 66.5 % regular chow, w/w) for 1 month and then intraperitoneal injection with 25 mg/kg streptozoticin(STZ) in female inbred Wistar rats. Rhein was continuously given 100 mg?kg-1?day-1 for 6 months 1 week after STZ injection in rhein-prevented group, and 1 month after STZ injection in rhein-treated group. Blood and urinary biochemistry and renal morphology were evaluated at divers times. Results Rhein ameliorated hypertriglyceridemia and hypercholesterolemia, but had few effect on the level of plasma glucose in both rhein-prevented group and rhein-treated group. Excretion of urinary protein reduced markedly and stable-state plasma glucose (SSPG) level decreased in both groups as compared with diabetic group. Examination of kidney sections from both rhein-prevented group and rhein-treated group showed that the structural lesions of glomeruli including mesangial expansion, diffuse glomerulosclersis and thickening of glomerular basement membrane, as well as artery injury such as arteriolar hyalinosis, atherosclerosis were markedly improved as compared with diabetic group. Morphometry of glomeruli from both rhein-prevented group and rhein-treated group showed that glomerular grow and mesangial hypertrophy occurred in diabetic group were ameliorated. The accumulation of fibronectin examined by immunostaining in glomeruli was reduced in both groups. Conclusion Therapeutic intervention with rhein can halt the progression of diabetic nephropathy and prevent the development of glomerulosclerosis and vascular injuries in this animal model of type 2 diabetes mellitus.

Objective To investigate the relationship between serum uric acid ( SUA) concentration and urinary albumin excretion rate ( UAER) and carotid intima-media thickness (CIMT) in patients with type 2 diabetes mellitua (T2DM). Methods The clinical data of 372 patients with T2DM. including 184 males and 188 females, were collected. The correlations between SUA and the other clinical indexes were analysed by Pearson method, and multiple regression analysis was employed to examine the effects of various factors on UAER and CIMT. Results SUA concentration was higher in males than in females with T2DM (P <0. 01). and was positively correlated with UAER both in males and females with T2DM, even after adjustment for the creatinine clearance (r = 0.24, P < 0.01 for males; r = 0. 29, P < 0.01 for females). Positive correlation was found between SUA concentration and CIMT in females (r =0. 29, P < 0. 01). Multiple regression analysis demonstrated that SUA concentration was an independent determinant of UAER for males as well as females (β=0.16, P<0.05 for males; β=0. 20, P < 0. 05 for females), and was also an independent determinant of CIMT for females (β =0.16, P <0.05). Conclusion SUA plays an important role in the progression of diabetic nephropathy and cardiovascular diseases in patients with T2DM. SUA control may provide a novel approach for the treatment of diabetic nephropathy and vascular complications.

Background Laser assisted in situ keratomileusis (LASIK) for myopia will change corneal asphericity and further affect the quality of vision.However,how operating parameters such as ablation depth and optic zone diameter affect corneal asphericity is still rarely reported.Objective Aim of this study was to investigate the influence of corneal ablation depth and optic zone diameter on corneal asphericity after LASIK for myopia.Methods This prospective study comprised 175 eyes of 89 patients with the spherical equivalent of (-5.93± 1.98)D and the best corrected visual acuity (BCVA) ≥ 1.0.The flap creation with the femtosecond laser combine iris recognize guided LASIK was performed on the patients who were available for the evaluation at postoperative 6 months.Corneal aspherical index (Q value) at the central corneal 6.0 mm were measured with Orbscan IIz-corneal topography before and 6 months after operation.Corneal ablation depth and optic zone diameter were recorded in operation.The changes of visual acuity and spherical equivalent before and after surgery were compared by self-control method,and the correlations between corneal ablation depth or optic zone diameter with alteration of Q value (AQ) after LASIK were assessed using multiple regression analysis.Results The mean spherical power,cylinder diopter and spherical equivalent were (-5.57 ± 1.89) D,(-0.71 ±0.55) D and (-5.93 ± 1.98) D before surgery,and those after surgery were (-0.25 ±0.30),(-0.14±0.22)D and (-0.32±0.37)D,showing significant differences between before and 6 months after LASIK (t=-32.39,-23.91,-35.18,all at P＜0.01).The Q values at the central corneal 6.0 mm were -0.13 ± 0.09 (-0.47-0.08) in preoperation and 1.09 ± 0.54 (0.22-2.51) in postoperation,with a significant increase in postoperation (t=29.37,P＜0.01).Corneal ablation depth was (95±28) μm and optic zone diameter was (6.32±0.26)mm.Ablation depth appeared to be positive correlation with AQ (β =0.803),and optic zone diameter showed a negative correlation with AQ (β =-0.149),with a multiple regression formula AQ =1.517+0.015×ablation depth-0.3 ×optic zone diameter.Conclusions LASIK for myopia increase corneal Q value.The increase of corneal ablation depth and decrease of optic zone diameter contribute to enlargement of corneal Q value.

ObjectiveTo analyze the CT appearances of primary pulmonary non-Hodgkin lymphoma(PPNHL)in order to improve its diagnosis.MethodsCT manifestations of 19 cases with PPNHL confirmed by pathology and clinical follow-up were retrospectively analyzed.ResuitsNodules 7 cases and masses 8 cases in PPNHL were ill-defined and markedly enhanced,in which air bronchogram was commonly seen.Muhiple patchy areas distributed in the bilateral lungs were found in 9 cases.Consolidation 7 cases was lobar and markedly enhanced,in which air bronchogram was commonly seen.Interstitial change manifested as bilateral diffuse ground-glass opacities and reticular shadow was found in 1 case.Mixed imaging manifestations were detected in 10 cases.Pleural effusion 4 cases was uncommon.Conclusion CT manifestations of PPNHL are varied,but some specific imaging features still exist,CT examination combined with clinical manifestations is helpful for the diagnosis of PPNHL.

Background: Endoscopic surgery of Western medicine has developed rapidly in treating ureteral calculi while traditional Chinese medicine (TCM) therapy also has its advantage, thus the integrated traditional Chinese and Western medicine therapy may have an even better efficacy in dealing with this problem. Objective: To observe the clinical effects of sequential therapy of Quantong Recipe, a compound traditional Chinese herbal medicine, combined with ureteroscopic laser lithotripsy on ureteral calculi. Design, setting, participants and interventions: A total of 151 patients with ureteral calculi (stone diameter of 3 to 21 mm) from Department of Urology, Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine were included, of which 106 patients with stone diameter of 3 to 10 mm were treated with Quantong Recipe for the first two weeks. Twenty patients with unexpelled stones and 45 patients with stone diameter of more than 10 mm were treated with ureteroscopic laser lithotripsy. The 65 patients except one open operation were divided into regular treatment group (32 cases) and regular treatment combined with Quantong Recipe group (32 cases) after lithotripsy. The efficacy was assessed after one week. Main outcome measures: Cure rate in the patients with stone diameter of less than 10 mm after two-week Quantong Recipe treatment was calculated, and clearance rate in the patients with residual stone for ureteroscopic laser lithotripsy after one-week Quantong Recipe treatment was also observed. Results: After taking Quantong Recipe for two weeks, the stones in 86 patients were completely discharged, and the stones in 6 patients were not completely discharged, but the unexpelled stones had moved down more than one segment of ureteral stenosis; the total response rate was 86.79% (92/106). The 64 patients with stones unexpelled or with stone diameter of more than 10 mm were treated with ureteroscopic laser lithotripsy, and the clearance rate of residual stone was 93.8% in regular treatment combined with Quantong Recipe group, and was 71.9% in regular treatment group, and there was a significant difference between the two groups (P<0.05). Conclusion: Sequential therapy of Quantong Recipe integrated with ureteroscopic laser lithotripsy demonstrates a significant advantage of integrated traditional Chinese and Western medicine therapy in treating ureteral calculi.

Objective: Vacuum-assisted closure(VAC) is a new technique for wound treatment,whose clinical application at home is but at the initial stage.The aim of this study was to investigate the procedure,therapeutic course and the effectiveness of the technique in the treatment of chronic wounds.Methods: This study included 12 cases of chronic or infected wound,which were more than 100 cm2 in size,either undermined,or drainage-obstructed,or difficult to heal despite over a month of previous treatment.We used the Freedom Negative Pressure Wounds Therapy Machine and the Ten-Step Management Procedure for a regular course of 30-50 days.We recorded and analyzed the pre-and post-treatment PUSH(pressure ulcer scale for healing) scores,healing modes,healing time and cure rate of all the cases.Results: The 12 cases were treated by VAC for(27.7 ? 22.6) days,of which 9 were cured,1 improved and 2 healed after moisture therapy followed by further treatment in the surgical department.The average healing time was(59.36 ? 22.88) days and the total cure rate was 91.7%.Age is positively correlated with healing time,but other factors showed no significant correlation with healing time and cure rate.Conclusion: The VAC technique is applicable to chronic wounds in patients of all ages,and the best therapeutic course is 30-50 days,which helps to raise the cure rate of intractable wounds.
