BACKGROUND:Different operation approaches can be selected during the repair of thoracolumbar fractures. Traditional posterior median approach wil cause great wound on patients, and easily induces some adverse consequences. OBJECTIVE: To compare the effects and biocompatibility of conventional posterior median approach and paraspinal approach fixation for treatment of thoracolumbar fractures. METHODS: A retrospective analysis was performed on clinical data of 53 cases of thoracolumbar fracture in the Shaanxi Province Nuclear Industry 215 Hospital from December 2012 to December 2013. They were divided into two groups according to approach method. The control group (n=27) received pedicle screw placement fixation through conventional posterior median approach. The observation group (n=26) underwent pedicle screw placement fixation through paraspinal muscle approach. After repair, they were folowed up for 12 months. Imaging results, pain score and perioperative relevant indexes were observed and compared in both groups. RESULTS AND CONCLUSION: Imaging examination was conducted before repair, immediately after repair and during final folow-up in both groups. The height of vertebral anterior border and kyphosis correction effect were good after different therapies in both group, but no significant difference was detectable between the two groups (al P > 0.05). These findings suggest that height of vertebral anterior border and kyphosis correction effect were identical between the two groups. Pain visual analog scale score was significantly lower in the observation group than in the control group at 24 hours and 3 days after repair and during final folow-up (al P < 0.05). Perioperative relevant indexes were analyzed in both groups. Intraoperative bleeding amount, drainage and bed time after repair were observed in the observation group, which showed significant advantages as compared with the control group (al P < 0.05). These results confirmed that compared with the traditional posterior median approach surgery, minimaly invasive pedicle screw placement through paraspinal muscle approach for thoracolumbar fractures can obtain better repair effects and biocompatibility.

Objective To investigate the blood glucose changes in critically ill patients taken continuous renal replacement therapy(CRRT)before treatment and at different time points after treatment. Methods Sixtyseven critically ill patients were enrolled in the study,of whom 13 cases were treated conventionally and assigned as pre-treatment control group,while the other 54 cases undertook CRRT were assigned as CRRT group. The CRRT group were further sub-divided into four groups according to CRRT time((CRRT time ＜6 h group(n = 18),CRRT time of 6 - 12 h group(n = 18),CRRT time ＞ 12 h group(n = 18);or sub-divided into two groups according to circulating blood temperature(≤ 36. 5 ℃ group(n =27)and ＞ 36. 5 ℃ group(n =27));or sub-divided into two groups by sugar substitute fluid replacement solution as the formula group(the standard level of sugar content was 6. 9 mmol/L(n = 27)and sugar-free replacement fluid group(n = 27);or sub-divided into two groups according to the Glasgow Coma score(GCS)(GCS ≤ 8 points group(n = 24)and GCS ＞ 8 group(n = 30). Blood glucose level at different time points were measured. Results The longer CRRT cycle time,lower temperature,sugar substitute fluid replacement fluid worse GCS score corresponded to more dramatic blood glucose fluctuation at different time points in CRRT group,and it took longer time for them to recover to normal blood sugar level Conclusions During the CRRT process insulin secretion was suppressed and led to increase of blood sugar. In most cases the blood glucose returns to normal after CRRT treatment over time,but a small number of cases require clinical intervention.

A growing body of evidence has indicated the important role of autophagy receptors in directing ubiquitinated or non-ubiquitinated cargos towards autophagy. Autophagy receptors bind to LC3 (microtubule-associated protein 1 light chain 3) on phagophore and autophagosome membranes, and recognize signals on cargoes in the delivery system of autophagy. However, the diverse domains in the receptor structures determine that their roles would never be limited to autophagy. Up to date, increasing numbers of the receptor proteins have been demonstrated to serve as a molecular link or switch participating in autophagic degradation, apoptosis or cell survival signals. Here, we highlight the non-autophagic roles of these receptor proteins to draw attention to this growing research topic.

Objective To discuss the clinical features and treatment of hepatogenous diabetes. Method Retrospective analysis was conducted in January 2002-April 2009 170 cases of clinical data in patients with liver cir-rhosis. Result 170 cases of liver cirrhosis 40 cases of diabetes, the incidence was 23.5% ,various types of cirrhosis may occur;typical "over three" obvious symptoms; 10 cases admitted tohospital when fasting blood glucose≥7.0 mmol/L, postprandial 2 hours blood glucose were ≥1.1 mmol/L;high level of total bilirubin,serum albumin,cholin-esterase,total cholesterol low. Given to diabetic diet and small doses of ct-glucosidase, short-acting insulin treatment; 26 cases of normal blood glucose, improvement in 8 cases (blood glucose 6. 1～11.1 mmol/L) ;6 deaths. Conclusion Prone to occur in patients with liver cirrhosis glucose metabolism disorders, its clinical features, treatment of liver damage and the need to take into account two aspects of diabetes, the use of insulin as the main.

[Objective] To study the methods of inducing bone mesenchymal stem cells(BMSCs)of rabbits into chondrocytes in vitro and the interaction of transforming growth factor ?1(TGF-?1),insulin-like growth factor-Ⅰ(IGF-Ⅰ)and basic fibroblast growth factor(bFGF).[Methods]BMSCs of rabbits were primarily cultured and subcultured in vitro,and then divided into four groups according to the difference of factors:group A receiving TGF-?1 and bFGF;group B receiving TGF-?1 and IGF-Ⅰ;group C receiving TGF-?1;group D receiving no cell growth factor.After three weeks all the four groups were detected by methyl thiazolyl tetrazolium(MTT)assay,measurement of glycosaminoglycan(GAG)and immunohistochemistry.[Results]Immunohistochemical detection of collagen Ⅱ was positive in groups A,B and C.The results of the MTT assay and the GAG content in groups A and B were obviously higher than those in groups C and D.[Conclusion]Rabbit BMSCs can be induced into chondrocytes under certain conditions.TGF-?1,IGF-Ⅰ and bFGF have synergy effect in the differentiation from BMSCs into chondrocytes.
