Objective To examine the induction effects of bone marrow mesenchymal stem cells(BMSCs) transfected with bone morphogenetic protein 7 (BMP7) gene differentiating into chondrocytes. Methods We observed the phenotype of cells which were stained with alcian blue and HE climbing to the six pore plate with invert microscope. The glycosaminoglycan (GAG) value in culture medium was detected in control group,BMP7 transfect and culture medium induced groups after 7,14 and 21 days using standard curve method. Standard curve was described using galacturonic-acid as reference substance. The content of collagen Ⅱ was detected by ELISA method. Results HE and Alcian blue staining showed that BMP7 gene transfection group and the group induced by fluid possess the characteristics of chondrocyte. BMP7 induced BMSCs differentiation to chondrocyte which secrete specific protein called collagen Ⅱ and GAG. Content of GAG were (17.1±3.4),(39.5±5.4),(40.8±6.1)mg/L in control group,BMP7 gene transfected group and induced group,collagen Ⅱ were (89.7±14.3),(152.8±14.5),(155.5± 19.3)μg/L in these three groups separately. Comparing with control group,GAG and collagen Ⅱ of BMP7 gene transfected group and culture medium induced group increased obviously(all P < 0.05),but there was no significant difference between BMP7 gene transfeeted group and culture medium induced group (P > 0.05). Conclusion This active protein induces BMSCs differentiating into chondrocyte,in a level similar to that of inducing medium.

BACKGROUND:For patients in intensive care unit (ICU), mechanical ventilation is an effective treatment to survive from acute illness and improve survival rates. However, long periods of bed rest and restricted physical activity can result in side effects. This study aimed to investigate the feasibility of early rehabilitation therapy in patients with mechanical ventilation. METHODS:A randomized controlled trial was carried out. Sixty patients, with tracheal intubation or tracheostomy more than 48 hours and less than 72 hours, were admitted to the ICU of the Affiliated Hospital of Medical College, Qingdao University, from May 2010 to May 2012. These patients were randomly divided into a rehabilitation group and a control group. In the rehabilitation group, rehabilitation therapy was performed twice daily, and the training time and intensity were adjusted according to the condition of the patients. Early rehabilitation therapy included heading up actively, transferring from the supine position to sitting position, sitting at the edge of the bed, sitting in chair, transferring from sitting to standing, and ambulating bedside. The patient's body mass index, days to first out of bed, duration of mechanical ventilation, length of ICU stay, APACHE Ⅱ score, highest FiO2, lowest PaO2/FiO2 and hospital mortality of patients were all compared between the rehabilitation group and the control group. The differences between the two groups were compared using Student's t test. RESULTS:There was no significant difference in body mass index, APACHE Ⅱ score, highest FiO2, lowest PaO2/FiO2 and hospital mortality between the rehabilitation group and the control group (P>0.05). Patients in the rehabilitation group had shorter days to first out of bed (3.8±1.2 d vs. 7.3±2.8 d; P=0.00), duration of mechanical ventilation (5.6±2.1 d vs. 12.7±4.1 d; P=0.005) and length of ICU stay (12.7±4.1 d vs. 15.2±4.5 d; P=0.01) compared with the control group. CONCLUSION:Early rehabilitation therapy was feasible and effective in improving the outcomes of patients with mechanical ventilation.

OBJECTIVETo establish a rat model of low calcium diet related hyperoxaluria and explore its features.

METHODSBy means of randomized blocks design, totally 24 SD male rats were divided into low calcium diet group, medium calcium diet group, and high calcium diet group. Each group was sequentially fed on different calcium diets for 3 days. The urinary volume within 24 hours was recorded, the consistency of urinary oxalate by high-efficiency liquid chromatography, and the consistency of urine creatinine by automatic biochemical analyzer. The consistency was corrected to the output of urinary oxalate of rats in 24 hours, and the results were evaluated by repeated measurement of variance analysis and multivariate analysis of variance.

RESULTSThe output of urinary oxalate of rats in 24 hours varied with time (F=7.893, P0.05). The output of urinary oxalate of rats in 24 hours varied with group division (F=3.565, P<0.05). The output of urinary oxalate in 24 hours in three groups on the third day was significantly higher than that on the first day (P<0.05).

CONCLUSIONBy controlling the calcium intake, we successfully established the model of low calcium diet related hyperoxaluria in rat.

Objective To investigate the level and clinical significance of D-dimer(D-D) and fibrinogen(Fib) in patients with first-episode schizophrenia.Methods The 83 patients with first-episode schizophrenia from March 2014 to December 2016 were selected as the study group,meanwhile 58 healthy subjects without mental illness and major somatic diseases were selected as control group.Two groups of subjects were collected from fasting sodium citrate anticoagulated plasma to detect level of D-D and Fib.Resuits The level of D-D in the first-episode schizophrenia group was(240.42±245.78)μg/L,which was significantly higher than that in the control group(76.53±71.25)μg/L,and the difference was statistically significant(P＜0.05).While the level of Fib in the first-episode schizophrenia group (2.62 ± 0.49) g/L was significantly lower than that of the control group (2.87 ± 0.65) g/L,and the difference was statistically significant(P＜0.05).The increase in D-D levels and the reduction in Fib levels in patients with firstepisode schizophrenia were not related to gender.Conclusion he patients with first-episode schizophrenia in acute stage may have hypercoagulable status and secondary fibrinolysis.

OBJECTIVETo investigate the effect of FK506 on the cavernous nerve regeneration after injury and to discuss its possible action mechanisms.

METHODSFifty-four male adult Sprague-Dawley rats were randomized into three groups: Group 1 (sham control), Group 2 (unilateral cavernous nerve ablation), and Group 3 (unilateral cavernous nerve ablation with subsequent injection of FK506). Electrostimulation of the cavernous nerve was performed at 1 and 3 months after surgical injury. The intracavernous pressure was continuously detected and the rats were followed by nicotinamide adenine dinucleotide phosphate diaphorase (NADPH-d) staining to identify NOS in the penile nerve fibers of the penile shaft.

RESULTSAt 1 month, the number of NOS-positive nerve fibers significantly decreased with no statistical difference among the three groups except the sham controls (P > 0.05). At 3 months, electrostimulation revealed greater maximal intracavernous pressure in Group 3 than in Group 2 (P < 0.01). Furthermore, the number of NOS-positive nerve fibers showed a significant increase (P < 0.01), but not in Group 2 (P > 0.05).

CONCLUSIONFK506 injection enhances the regeneration of cavernous nerves after injury and the recovery of erectile function in rats.

OBJECTIVETo evaluate the roles of cell adhesion, multidrug resistance and cell proliferation in short-term recurrent cases with superficial bladder cancer, and the prognostic value of the three indexes.

METHODSImmunohistochemical staining for E-cad, P-gp and Ki-67 was performed on the tumors of 100 patients with stage T0-T1 transitional cell carcinoma of the bladder who had been included in a retrospective research by follow-up.

RESULTSE-cad and P-gp expression was positive in 51 (43.2%)and 17 (14.4%) of the tumors, respectively and mean proliferation index (PI) was 22.1%. The decrease in E-cad expression was accompanied with the increasing recurrent episodes (P < 0.05), while increase of P-gp expression and PI were accompanied with the increasing recurrence episodes (P < 0.05). There was significant difference according to E-cad, P-gp positivity and between T(1)G(3) patients and no-T(1)G(3) patients (P < 0.05). There was negative correlation of E-cad expression with P-gp expression and PI.

CONCLUSIONSMinimum adhesion, strong drug resistance and maximum proliferation are the main factors that promote short-term recurrence of superficial bladder cancer and also the inherent reasons for easy recurrence and high malignancy of T(1)G(3) tumors. During this course, the three aspects may interact.

Neurotrophins play significant roles in the development, differentiation and regeneration of many neurons. The abnormal changes of neurotrophins are one of the nosogenesis of diabetic peripheral neuropathy. Erectile dysfunction (ED) in diabetes is multifactorial and one of the most important causes is the injury of pelvic splanchnic nerves. Neurotrophins therapy shows exact effects on ED with pelvic splanchnic nerves injured. Recent researches indicates that the same treatment has the similar therapeutic effects on the ED animals with diabetes. Neurotrophins therapy develops a new way for us to cure the ED with diabetes.

OBJECTIVETo observe the effect of reducing the incidence of CAUTI by spraying the long-acting antibacterial material JUS on the surface of catheter and urethral orifice.

METHODSSixty male patients, aged from 68 to 79, with indwelling catheter after TURP were divided randomly into two groups (control group and treated group), each consisting of 30 patients. For the control group, their urethral orifice was treated conventionally twice a day; while for the treated group, in addition to the conventional treatment of their urethral orifice, the catheter and their urethral orifice were sprayed with the long-acting antibacterial material JUS twice a day.

RESULTThe number of cases of urinary tract infection in the treated group during catheterization was evidently less than those of the control group (P < 0.01), so the difference was of remarkable significance.

CONCLUSIONThe long-acting antibacterial material, after spraying on the wall of catheter and urethral orifice of the patients with indwelling catheter, may form a layer of physically antibacterial molecular film to prevent the formation of a bacterial biological film and effectively reduce the incidence of CAUTI.
