Objective To investigate the efficacy of percutaneous laser disc decompression(PLDD)combined with injection of collagenase through a target location for treatment of lumbar intervertebral disc protrusion.Methods Ninety patients with lumbar intervertebral disc protrusion scheduled for discolysis,aged 31-52 yr,weighing 58-70 kg,were randomly divided into 3 groups: PLDD group(group P,n = 29),collagenase injection group(group C,n = 31),PLDD combined with injection of collagenase through a target location group(group PC,n = 30).The puncture was performed under the guidance of CT.Group P was treated using PLDD.Group C was treated with collagenase injection.Group PC was treated with injection of collagenase after PLDD was completed.The therapeutic effect was assessed before operation and on day 7,30,60 and 90 after operation using M-JOA score.Results M-JOA grade was significantly higher at the each time point after operation in group P and PC,and on day 30,60 and 90 after operation in group C than that before operation(P ＜ 0.05).M-JOA grade was significantly lower on day 30 after operation in group P,while higher on day 30,60 and 90 after operation in group C and PC than that on day 7 after operation(P ＜ 0.05).M-JOA grade was significantly lower at the each time point after operation in group P and C than in group PC.Conclusion The therapeutic effect of PLDD combined with collagenase injection through a target location is stable for treatment of lumbar intervertebral disc herniation and better than that of PLDD or collagenase injection alone.

The aim of this investigation was to determine whether a PPARgamma2 Pro12Ala polymorphism was associated with insulin resistance, beta-cell function and hypertension in Chinese populations. 289 unrelated Chinese subjects first diagnosed Type 2 diabetes (HbAC1 < 6.0) were investigated, including 132 hypertensive diabetic (HTD) subjects, 157 normotensive diabetic (NTD) subjects. Blood pressure and anthropometric measurements were collected from all participants, as well as several venous blood samples during oral glucose tolerance test (OGTT). Biochemical measurements (high-density lipoprotein (HDL) and low-density lipoprotein-cholesterol (LDL), triglycerides) and PPARgamma2 Pro12Ala genotype were also determined. And insulin resistance and beta-cells function was assessed by HOMA-IR and HOMA-beta respectively. The frequency of subjects bearing the Pro12Ala was lower in the hypertension group (3.03%) than in the non-hypertension group (5.7%) (P < 0.05) after adjusted for age, BMI and gender. Hypertensive diabetic Pro12Ala subjects had lower fasting plasma glucose level (P = 0.0127), and better glucose tolerance 60 min after oral glucose (P = 0.0361). Moreover, plasma insulin concentrations at 60 min was lower than those without A variant (P = 0.0275), and both hypertensive Ala/Pro in HOMA-beta (P = 0.0455) and AUC for insulin (P = 0.0473) were higher, and HOMA-IR was lower (P = 0.0375) as compared with hypertensive Pro/Pro subjects. No association was observed between Pro12Ala genotype and BMI, total cholesterol, HDL- cholesterol or triglycerides in either group. Our findings suggested that the Ala 12 allele of the PPARgamma2 gene may improve insulin resistance and ameliorate beta-cell function reserves in T2DM with hypertension, and protect patients from hypertension in T2DM. As an important thrifty gene, environment factors may exerts an effect of PPAR gamma2 on glucose homeostasis and insulin resistance.

Objective To evaluate the efficacy of minimally invasive percutaneous intervertebral disc approach for treatment of sympathetic cervical spondylosis. Methods Fifty?six patients diagnosed as having sympathetic cervical spondylosis from January 2009 to August 2014, aged 22-64 yr, with the dis?ease course ranged from 6 months to 15 yr and a follow?up period of 6 months, were enrolled in the study. The related minimally invasive approach was selected according to the height of the diseased intervertebral space. When the ratio of the height of diseased intervertebral space∕normal intervertebral space≤1∕3, per?cutaneous radiofrequency ablation was used ( groupⅠ, n=19); when the ratio within the range of 1∕3-2∕3, percutaneous laser disk decompression was used ( groupⅡ, n=12); when the ratio≥2∕3, low?tem?perature plasma radiofrequency ablation was used ( group Ⅲ, n=25) . Before operation, at 2 weeks after operation, and at 1, 3 and 6 months after operation, the sympathetic symptoms were evaluated using the 20?point score. At 2 weeks and 6 months after operation, the patients′ subjective satisfaction was assessed and graded ( excellent, good, medium and poor ) . Results All the patients were followed up for 6 months. The sympathetic symptom scores were significantly lower at each time point after operation in Ⅰand Ⅲ groups and at 2 weeks and 3 and 6 months after operation in group Ⅱ than those before operation
( P<0.05) . The excellent and good rate of patients′subjective satisfaction was 67.9% at 2 weeks after op?eration, and 76.8% in the last follow?up period at 6 months after operation. Conclusion The minimally invasive percutaneous intervertebral disc approach has a marked short?term effect on sympathetic cervical spondylosis.

Objective To explore the effects of motor training in sulfureted hydrogen miniral spring on neurological function after spinal cord injury (SCI). Methods 80 SCI patients were divided into treatment (n=40) and control group (n=40). They all accepted comprehensive rehabilitation, while the treatment group accepted motor training in sulfureted hydrogen miniral spring in addition. They were assessed with ASIA scale, modified Barthel index (MBI), Ashworth scale, visual analogue scale (VAS) and limbs circumference. Results There was not significant difference between both groups after treatment in ASIA scores of motor and sense, but was in Ashworth scale (P<0.05), VAS (P<0.01), limbs circumference (P<0.01), MBI (P<0.01, not in walk), which the treatment group improved more. Conclusion Motor training in sulfureted hydrogen miniral spring can further improve the activities of daily living and neurological function
