BACKGROUND:Traditional bladder repair methods have many problems such as damage to normal organ function and many postoperative complications. Tissue engineering technology provides a new way for bladder repair.
OBJECTIVE:To explore the feasibility of constructing tissue-engineered bladder with vascular endothelial growth factor (VEGF) nanoparticle-bacterial celulose (BC) composite scaffold with rabbit lingual epithelial cels andtonguemuscle cels.
METHODS:Rabbit lingual epithelial cels andmuscle cels were successively implanted onto the BC scaffold (control group) and VEGF-BC scaffold (experimental group). Six rabbits were taken to make bladder defect models and randomized into two groups: experimental group implanted with VEGF-BC scaffold carrying autologous lingual epithelial cels andtonguemuscle cels,and control group implanted with BC scaffold carrying autologous lingual epithelial cels andtonguemuscle cels. Specimens were taken from the two groups for urographic evaluation and histological examination at 3 months after implantation. Meanwhile, the urodynamic tests were performed.
RESULTS AND CONCLUSION:The experimental group showed the relatively complete bladder, and the control group showed a smal-area filing defect of the bladder. The maximum bladder capacity and bladder compliance in both two groups were decreased after implantation, especialy significantly in the control group (P< 0.05). In the control group, it failed to build a complete epithelial cel layer, and the muscle layer and microvessels were formed a little. In the experimental group, the complete epithelial cel layer was formed, and a larger amount of muscle layers and capilaries appeared. These findings indicate that the VEGF-BC scaffold carrying lingual epithelial cels andtonguemuscle cels can be used to construct thetissue-engineered bladder.

"Postpartum Body pain"refers to such symptoms as body pain,numbness,heaviness,arthralgia and even paralysis in a woman during the postpartum period.Besides the above symptoms,the patient may also have other symptoms like sleep disorder,emotional hindrance,somatization symptoms such as fatigue,sleepy,and chest distress,etc.This disease may be considered as somatization symptoms due to postpartum depression,but actually it is a psychogenic disorder.Clinical observation showed there were no clinical changes of objective signs such as red,swelling and fever;Laboratory examinations showed there was no ahnormal manifestation.This article primarily discussed"postpagtum body pain"from medicopsychological angle,hoping to help people get a right recognition of this disease.

Objective To explore the characteristics of polysomnography (PSG) of depressed patients and the correlation between rapid eye movement (REM) and severity degree of depression. Methods Polysomnography was used to assess patients'sleep condition and Montgomery-Asberg depression scale (MADRS) was used to assess the severity degree of depression. 90 patients and 30 healthy controls were included. Results Compared to healthy controls,sleep progress of depressed patients changed as follow:prolonged sleep latency((25.2 ±15.25) minutes) ,lowered sleep efficiency(0.853 ±0.11) ;the architecture of sleep also changed:percentage of stage 1 increased( (27.7 ± 16.38) % ),percentage of REM sleep increased( (22. 8 ± 6. 1 ) % ) , percentage of stage 2 decreased ((40.2±11.3)%), percentage of slow wave sleep decreased ((11.8 ±9. 32)%); REM sleep significantly changed; decreased REM latency((79. 27 ±30. 44) minutes) , increased REM activity((129. 0 ±53. 12) u) .increased intensity of REM((36.7 ±14.0)u/min), increased REM density((159.2 ±57.2)u/min) were observed in depressed patients. There was no obvious correlation between the variance of REM and severity degree of depression. Conclusion There are a series of changes in sleep progress, architecture and REM sleep of depression and the change of REM sleep can be specified to diagnose depression. However,there is no causality between REM variance and severity of depression.

Objective To study the clinical value of acoustic radiation force impulse imaging (ARFI) in patients with ischemic type biliary lesion (ITBL) after orthotopic liver transplantation. Methods Between July 2012 to January 2013, forty-one patients in General Hospital of the People′s Liberation Army were enrolled in this study who were admitted for post-transplantation follow-up. Among them, 15 patients were diagnosed as ITBL by ultrasonography. Besides conventional ultrasonography, ARFI was used to detect the shear wave velocity (SWV) of liver tissue at depth of 4 cm and 5 cm respectively. Simultaneously liver function test was performed. Independent-samples t test was performed to compare the difference of SWV between ITBL and non-ITBL group at the same depth. Paired-sample t test was performed to compare the difference of SWV for the same ITBL patient. Pearson correlation analysis was used in analyzing the relation between SWV and liver function. Results The average SWV in depth of 4 cm was (1.561±0.425) m/s and (1.121±0.160) m/s in ITBL and non-ITBL group, respectively. Signiifcant differences were found among the ITBL and non-ITBL groups (t=-3.173, P=0.01). The average SWV in depth of 5 cm was (1.608±0.545) m/s and (1.175±0.173) m/s in ITBL and non-ITBL group, respectively. Signiifcant differences were found among the ITBL and non-ITBL groups (t=-2.454, P=0.034). There was no signiifcant difference between SWV measurements at different depth for the same ITBL patient. For all patients, SWV at different depths were both strongly correlated with alkaline phosphatase (r=0.656, 0.667, respectively;both P=0.000) andγ-glutamyl transpeptidase (r=0.482, P=0.007;r=0.508, P=0.004). Conclusion The liver stiffness measurement is valuable for the clinical evaluation of post-transplantation ITBL.

Objective: To compare the molecular weight of sodium hyaluronate in the injection determined by three methods. Methods:Viscometry was used to determine the molecular weight of sodium hyaluronate. The molecular weight and its distribution ( Mw/Mn) was measured by size exclusion chromatography ( SEC) and the combination of multi-angle laser light scattering instrument and size exclusion chromatography( MALLS-SEC) . Results:The results of MALLS-SEC were close to those of viscometry, and Mw/Mn was obtained simultaneously. The average value of molecular weight of three batches of samples was 991962, 1007438 and 990232 with RSD of 6. 5%, 4. 6% and 2. 2%, respectively(n=4). The average value of Mw/Mn was 1. 6, 1. 6 and 1. 6 with RSD of 7. 2%, 3. 2% and 3. 2%, respectively(n=4). Conclusion:MALLS-SEC shows better accuracy and precision, and can be used in the quali-ty control of sodium hyaluronate samples.
