Objective To investigate the effect of Liuwei Dihuang decoction combined with Taohong Siwu decoction in the treatment of traumatic renal contusion and laceration with long time no absorption of hematoma.Methods 166 patients with traumatic renal contusion and laceration with long time no absorption of hematoma from the department of urinary surgery from June 2014 to July 2016 in our hospital were selected and divided into two groups,83 cases in the control group treated with routine conservative treatment,83 cases in the experiment group received Liuwei Dihuang decoction combined with Taohong Siwu decoction on the basis of the control group,hematoma absorption,the scope of the hematoma of the kidney,the hemodynamic parameters of renal artery,the level of serum inflammatory factors,and the clinical effect were compared after the treatment.Results After treatment,the effective rate in the experiment group 93.98% was higher than the control group 77.11% (P<0.05);Compared with the control group,the beginning of absorption time of kidney hematoma,disappearance time of microscopic hematuria and the hospitalization time were shorter in the experiment group after treatment, the scope of perirenal hematoma was smaller after 2,4,12 weeks of treatment,the levels of Vmax and Vmin in renal aorta were higher,levels of AT and RI were lower after treatment, serum levels of TNF-α, IL-8, IL-1, IL-6 were lower after treatmentwith significant difference ( P <0.05 ). Conclusion Liuwei Dihuang decoction combined with Taohong Siwu decoction can significantly promote the absorption of hematoma in patients with traumatic renal contusion and laceration,improve the blood flow of renal artery,reduce the inflammatory reaction index, promote the recovery of renal injury,shorten the length of hospital stay.

Objective To investigate the mixed protamine zinc recombinant human insulin lispro injection on glucose metabolism, immune function in patients with type 2 diabetes and its inflammatory mechanisms.Methods 125 patients enrolled were randomly divided into two groups according to the random number table: control group (n =61) and observation group (n =64).The control group were received conventional treatment, observation group were received mixed protamine zinc recombinant human insulin lispro injection on the basis of control group, with a course of three months of both groups.The fasting blood glucose (FBG), 2h post prandial blood glucose (2hPG), glycated hemoglobin (HbA1c), fasting insulin, insulin resistance index ( IRI) , CD4 +, CD8 +, CD4 +/CD8 +changes and inflammatory cytokines levels were compared before and after treatment between two groups. Results The level of FBG, 2hPG, HbA1c after treatment was respectively lower than that before treatment in both groups (P<0.05), and the above indexes of observation group after treatment was respectively lower than that of control group (P<0.05).The level of fasting insulin, IRI after treatment was respectively lower than that before treatment in both groups (P<0.05), and the above indexes of observation group after treatment was respectively lower than that of control group (P<0.05).The level of CD8 +was lower, CD4 +, CD4 +/CD8 +was higher after treatment than that before treatment in both groups, respectively (P<0.05), and the CD8 +level of observation group after treatment was lower, CD4 +, CD4 +/CD8 +was higher than that of control group, respectively (P<0.05).The level of TNF-α, IL-6, CRP after treatment was respectively lower than that before treatment in both groups (P<0.05), and the above indexes of observation group after treatment was respectively lower than that of control group (P<0.05).Conclusion The mixed protamine zinc recombinant human insulin lispro injection can significantly improve glucose metabolism in patients with type 2 diabetes, and enhance immune function, reduce inflammation, thereby reducing the incidence of cardiovascular events.

Objective To compare the efficacy of tibial tuberosity osteotomy (TTO) combined with medial patellofemoral ligament reconstruction (MPFLR) with simple TTO in treatment of recurrent patella dislocation associated with patella alta.Methods From July 2010 to December 2015,50 patients with recurrent patella dislocation and patella alta were included in this study.There were 15 males and 35 females with an average age of 20.6 years.These patients received surgical treatment and their clinical data were collected and retrospectively analyzed by case-control study.According to surgical methods,patients were divided into TTO group (32 cases) and MPFLR + TTO group (18 cases).The differences between preoperative status and postoperative status were evaluated by knee function scores including Tegner,international knee documentation committee (IKDC),Kujala scores,knee injury and osteoarthritis outcome score (KOOS).Patellar stability was checked at the last follow-up visit.Results The TTO group and MPFLR + TTO group were followed up for (50.9 ± 17.8) months and (22.3± 10.1)months,respectively.Two patients occurred recurrent dislocation in TTO group,who showed positive in both extrapolation test and extrapolation apprehension test at 0°flexions of knee.All patients in MPFLR + TTO group did not occur recurrent dislocation,who showed negative in both extrapolation test and extrapolation apprehension test at 0° flexions of knee.There was no significant difference between preoperative and postoperative results in TTO group in Tegner score (P ＞ 0.05),KOOS scores in pain and daily life activities subdomains (P ＞ 0.05),while differences in the rest of scores were statistically significant (P ＜ 0.05).Compared with TFO group,the differences of all scores were statistically significant (P ＜ 0.05) and KOOS scores in the pain and daily life activities subdomains were significantly improved postoperatively in MPFLR + TTO group P ＜0.05).Conclusions For patients with recurrent patellar dislocation associated with patella alta,both surgical methods are found to be effective.Postoperative improvements in pain and daily life activities are less obvious in TTO.While postoperative improvements in pain and daily life activities in MPFLR + TTO are superior to those of TTO.

Total knee arthroplasty (TKA) is an effective treatment for end-stage knee disease, with the postoperative alignment, component position, soft tissue balance, and prosthesis matching being key factors for the success of TKA. In order to achieve more accurate postoperative alignment and component position, better soft tissue balance and prosthesis matching for longer prosthesis longevity, better postoperative function and higher patient satisfaction, various intelligent accuracy technological aids such as computer assisted navigation (CAN), patient specific instrumentation (PSI), surgical robots, microsensors, customized implants (CI) and personalized 3D preoperative planning have emerged and are given high expectation. In this paper, the authors review the application and research progress of the above technological aids mainly from aspects of alignment, component position, clinical outcomes and cost analysis, so as to provide a reference for the application of related technological aids in TKA.
