Objective To find the differences of bladder and urethra dysfunction between sacral spinal cord injury and Thoracolumbar spinal cord injury.Methods According to the criteria of inclusion and exclusion, we collected 30 patients in the study group.There were 22 males and 8 females, aged 17 -74 ( mean, 47 ) years, with duration between 7 - 36 ( mean, 18) months.There were nineteen cases of thoracolumbar spinal cord injury and 11 cases of sacral spinal cord injury in the study group.We conducted a retrospective analysis of the urodynamic data of the 30 patients in the group.They were divided into a sacral spinal cord injury group and a thoracolumbar spinal cord injury group according to the location of the site of injury.The urodynamic findings of the two groups were comparable.SPSS 16.0 was used to compare the differences between the groups by ANOVA/rank sum test.Results We measured the free flow rate parameters between thoracolumbar and sacral spinal cord injury groups.The maximum free flow rate was ( 13.0 ±5.1 ) vs ( 13.0 ±5.8) ml/s, the free flow rate at 2 s was (6.5 ±5.1 ) vs (6.9 ±6.4) ml/s, the mean free flow rate was (5.4± 2.4) vs ( 3.4 ± 0.5 ) ml/s, urine output volume was ( 279.1 ±131.1 ) vs (450.0 ± 26.6) ml and the residual urine volume was (209.5 ± 180.7 ) vs (434.0 ± 215.0) ml.The residual urine volume and urine output volume of sacral the spinal cord injury group was higher than the thoracic spinal cord injury group (P ＜ 0.05).We also measured the the cystometric parameters.The maximum urinary flow rate was (16.0±23.3) vs (7.1 ±3.3) ml/s, average flow rate was (4.6 ±2.3) vs (3.9 ± 2.3) ml/s, the flow rate after voiding 2 s was (4.6 ± 3.1 ) vs (2.2 ± 3.2) ml/s, urine output volume was (268.4 ± 113.9) vs ( 129.0 ± 97.9) ml, detrusor pressure of maximum flow rate was (58.8 ± 22.0) vs (56.5 ± 14.5) cm H2 O, flow rate of maximum detrusor pressure was (4.8 ± 2.0) vs (4.8 ± 4.4) ml/s,the maximum detrusor pressure was (68.0 ± 31.0) vs (54.6 ± 20.2) cm H2O and the average pressure of voiding period was (47.4 ±20.0) vs (42.6 ± 13.9) cm H2O.The urine output volume of the thoracolumbar spinal cord injury group was lower than sacral spinal cord injury group ( P ＜ 0.05 ).There were no significant differences in bladder sensation and coordination of bladder/urethra between the thoracolumbar spinal cord injury group and the sacral spinal cord injury group (P ＞ 0.05).The incidence of low compliance bladder in the thoracolumbar spinal cord injury patients (4/11) was higher than the sacral spinal injury group, the incidence of high compliance bladder in the sacral spinal cord injury patients (11/19) was higherthan the thoracolumbar group.Conclusions The urodynamics' difference between the sacral spinal cord injury group and thoracolumbar spinal cord injury group was observed in bladder compliance and bladder detrusor contractility changes.Relatively, the incidence of decreased detrusor contractility and high compliance bladder in sacral spinal cord injury patients was higher, and the cidence of detrusor hyperreflexia and low compliance bladder in thoracolumbar spinal cord injury patients was higher.

Objective To evaluate the surgical characteristics and clinical effect of percutaneous reduction with kirachner wire assisted by a small lateral incision approach for poking reduction and allngraft bone transplantation in treating compressive intra-articular calcaneal fractures. Methods A retrospective analysis was performed among 17 patients with compressive intra-articular calcaneal fractures (Sanders Ⅱ to Ⅲ ) treated by percutaneous reduction with kirachner wire assisted by a small lateral incision approach for poking reduction and allograft bone transplanta-tion. Results All the patients were followed-up for an average time of 13.5 months. The wound of 15 feet achieved primary healing, the acute rejection was found in 2 patients. The Bohler's angle was (9.58±5.25)° and Gissane an-gle was (101.15±13.83)° preoperation and was (33.55±4.17)° and (113.25±12.17)° immediate postopera-tion, showing statistically significant differences pre-and postoperation(P < 0.05). By the lately follow-up, the Bohler angle was (31.65±7.72)° and Gissane angle was (111.15±8.68)°, also showing statistically significant differ-ences when compared to preoperation (P < 0.05), there was no statistically significant differences (P > 0.05) when compared with normal X-ray. Conclusion That percutaneous reduction with kirschner wire assisted by a small lateral incision approach for poking reduction and allograft bone transplantation in treating the compressive intra-articular cal-caneal fractures (Sanders Ⅱ to Ⅲ) is minimally invasive, less complication, and it enables satisfactory recoastruc-tion of bone defects and allows metanatomic reduction and functional recovery, also maintaining restoration of calcane-al height and anatomic reduction of the posterior facet.

In order to advance the public hospital reform, the performance tests and management were strengthened to promote the rapid development of the hospital. The status of average daily bed ocupation, the number of outpatients and the natural birth rate increased while the drug proportion declined. Some departments were the top level in Hebei, departments of gynaecology and pediatrics were in the leading level in Tangshan.

Objective To explore the reliability of patients' sensation of the need to urinate,and to investigate the optimal volume and duration of bladder filling and training method for the stability of bladder filling. Methods From 2014 to 2015,Fifty patients with pelvic tumor were divided into group A and group B,according to whether they had the history of diseases or surgery in the pelvis or urinary system. Both groups received training of the sensation of the need to urinate. The training required patients to drink a fixed volume of water every time they emptied the bladder. The bladder capacity was measured by a bladder scanner ( BladderScan BVI 9400) ,and a rating scale of the sensation of the need to urinate was completed at 30 min,45 min,1 h,and over 1 h when the patient sensed the limit for bladder capacity. The optimal volume and duration of bladder filling or optimal frequency for the training were explored. The paired t-test method was performed for the difference between the predictive value and the measured value,Pearson method was performed for correlation between the sensation of the need to urinate and the measured value. Results In the A and B groups,there was no significant difference between the predicted value and measured value ( A:predicted value and measured value P=0. 777,B:predicted value and measured value P=0. 061) ,suggesting that the measured value could be used to reflect the predictive value. Compared with group B,group A had a higher correlation between the sensation of the need to urinate and the measured value ( rA=0. 812, rB=0. 762).The correlation between the predictive value and the measured value became the highest at 45 min and 1 h ( r=0. 858 and 0. 916) ,and the corresponding bladder filling volume and score of the sensation of the need to urinate were 330-450 ml and 4-6,respectively. The correlation between the predictive value and the measured value increased with the frequency of the training ( r2=0. 914, r3=0. 917, r4=0. 930, r5=0. 951,r6=0. 962) . Conclusions Before radiotherapy,patients with pelvic tumor should received at least 4-6 rounds of the training of bladder filling. Patients should drink 800-1 400 ml of water every time they empty the bladder,and the optimal bladder filling volume and the reliable and stable sensation of the need to urinate will be achieved after 45 min-1 h. For the patients with the history of urinary system diseases or pelvic surgery,the bladder filling volume needs to be measured using a bladder scanner ( BladderScan BVI 9400) during the training before radiotherapy.

Objective To investigate the application of stroke volume variation (SVV) in directing management of elderly septic shock patients. Methods Patients who were diagnosed with elderly septic shock and supported with mechanical ventilation were in?cluded (n=28). They were divided into control group (n=13) and SVV group (n=15). Volume recovery was directed by CVP (central ve?nous pressure ) in control group and by SVV and CO (cardiac output) in SVV guoup respectively. Blood lactate, oxidation index, CVP , MVP, NT-proBNP, time of recovery, the length relying on mechanical ventilation and Vigileo parameters were compared after volume resuscition. During the period of treatment, the incidence of acute left ventricle dysfunction within 24 hours, MODS within 28 days and mortality rates of all causes were compared between these two groups. Changes in SVV, cardiac output (CO) and systemic vascular re?sistance (SVR) in SVV group before and after resustation were recorded. Results Blood lactate acid and NT-proBNP were significant?ly lower in SVV group compared with those in control group whereas oxidation index in SVV group were significantly higher than that of control group. The time of resuscitation and the duration relying on mechanical ventilation were shorter in SVV group than those in control group. On the contrary, the incidence of acute left ventricle dysfunction,MODS and all mortality rates were not significantly different between these two groups. There were significant differences between hemodynamic variables such as SVV, CO in SVV group before and after resuscitation. Conclusion SVV may direct volume resuscitation more effective in elderly septic shock than CVP does.

[Objective] To evaluate clinical effect of total hip arthroplasty(THA)with a short-neck and straight stem in patients with osteoarthritis secondary to developmental dysplastic hip with high dislocation.[Methods]From June 2002 to October 2007,total hip arthroplasties with a short-neck and straight stem were performed for 11 patients(12 hips)with osteoarthritis secondary to developmental dysplastic hip with high dislocation.All were females with an average age of 51 years(range from 41 to 68 years).The operations were performed through a posterolateral approach.All the acetabular cups were reconstructed at the original anatomic location,and structural autogenous bone-grafting was performed if the cup was not covered enough by host bone.Short-neck and straight femoral stems were used with cement fixation.During operation,the soft tissue around hip was released extensively.[Results]After surgery,the center of the hip had an average distal translation of 4.5cm(range from 3.8 to 4.8 cm)and the limb length had an average increase of 3.9cm(range from 3.6 to 4.3 cm).All the patients were followed up for a mean time of 36 months(range from 10 to 66 months).All structural autografts united and none of acetabular and femoral components showed loosening.No radiolucent line was observed at the bone-cement and at the implant-cement interface around femoral stem.No patient had sciatic or femoral nerve palsy.The mean Harris score increased from preoperative 41.8 points to postoperative 86.2 points.[Conclusion]THA with a short-neck and straight stem for treatment of osteoarthritis secondary to developmental dysplastic hip with high dislocation avoids femoral shortening osteotomy and greater trochanter osteotomy when the center of hip had a distal translation less than 5cm in preoperative plan,and this choice provides satisfactory results at early-term follow-up.

Chronic obstructive pulmonary (COPD) has significant extra pulmonary effects, which could induce atrophy of peripheral skeletal muscle and respiratory muscles, and significantly influence the respiratory function and quality of life. Muscle nuclear factor (NF)-κB activation plays a key role in the skeletal muscle atrophy. This article discussed the potential mechanisms on how NF-κB signaling pathway increasing protein breakdown and reducing muscle regeneration. On this basis, we explored the role of NF-κB in skeletal muscle at-rophy in patients with COPD during exercise.

Objective To summarize our preliminary experience and evaluate the clinical value of laparoscope diagnosis and treatment for annular pancreas in neonates.Methods A retrospective review of laparoscope diagnosis and treatment for annular pancreas in 9 children from September 2009 to January 2013 was performed.Among them,5 were male,4 were female.The age was ranging from 1 to 13 d.A lowerpressure pneumoperitoneum of 5 ～ 8 mm Hg (1 mm Hg =0.133 kPa) was used.Eight cases of diamond duodenal anastomosis were performed under laparoscope after the diagnosis was established,and 1 case underwent procedure through slightly enlarged umbilical port site.Results Eight cases of diamond duodenal anastomosis were performed under laparoscope,and the operation time was 80 ～ 140 min (mean 105 min),in 1 case it was performed through umbilical port incision,the operation time was 64 min,and the length of incision was about 2.5 cm.Feedings were started at postoperative day 4 to 7 (mean 5 d),and patients were discharged at postoperative day 8 to 14 (mean 10 d).The cases were followed-up for 3 ～ 20 months (mean 6.7 months),and I case complicated with anal atresia died of pneumonia 6 months later.Other cases were uneventfully recovered and symptoms were alleviated with normal gastroenterological function,no preoperative symptoms recurred,and the nutrition and growth status was excellent.Conclusions Annular pancreas can be diagnosed through laparoscopy.Laparoscope diagnosis and treatment for annular pancreas has the advantages of small incision,micro-invasion and faster recovery,can be safely performed in neonatal period.

Objective To evaluate the clinical efficacy of ureteroscopy for the diagnosis and treatment of renal colic. Methods A total of 50 cases of renal colic were diagnosed and treated by ureteroscopy. Stones with size smaller than 0 5 cm were removed, but lithoclasty was performed on those stones with size bigger than 0 5 cm. In addition, J shaped catheters or ureteral catheters were indwelt for drainage. Results Successful removal of stones and lithoclasty were achieved in 12 and 30 cases, respectively. No urolithiasis and other lesions were found in 3 cases. Improvement was found in those cases with indwelt catheters. The average stay was 4-5 d. Correlative etiological factors were found in 2 patients by ureteroscopy. Conclusion Transurethral ureteroscopy is an effective and safe method for the diagnosis and treatment of renal colic.
