BACKGROUND: Studies in recent years have suggested the involvement of chemoattractant cytokines in the recruitment of peripheral blood cells to the injured spinal tissue. Monocyte chemoattractant protein-1(MCP-1) belongs to the CC-type chemokines and is capable of specific chemotactic attraction of the macrophages.OBJECTIVE: To observe MCP-1 expression in the serum of patients with acute spinal cord injury and explore the possible mechanism of secondary spinal cord injury.DESIGN: A non-randomized and controlled concurrent pilot study.SETTING and PARTICIPANTS: Eight patients with acute incomplete spinal cord injury and 8 with compression fracture of the spine were treated in the Department of Orthopaedics, Renmin Hospital of Wuhan University during the period from January 2001 to December 2002. Another 8 healthy subjects were included as the controls.METHODS: In the next morning after hospitalization, totally(8-10) mL of fasting peripheral venous blood was collected from the patients and the serum separated for determination of MCP-1 level with enzyme-linked immunosorbent assay(ELISA) . Serum MCP-1 level was also measured in the healthy subjects in the same manner.MAIN OUTCOME MEASURES: Serum level of MCP-1 in each group.RESULTS: Serum levels of MCP-1 in the healthy subjects, patients with compression fracture of the spine and those with acute incomplete spinal cord injury were(124 ± 15), (184 ±21) and(428 ± 11) ng/L, respectively, with significant differences between any two groups( P < 0.01 ).CONCLUSION: MCP-1 may induce secondary inflammation by recruiting inflamnatory cells to the injury site and thus aggravate the spinal cord injury.

Background:The efficacy of standard triple therapy for eradication of Helicobacter pylori(Hp)is decreasing in recent years,and bismuth-containing quadruple regimen becomes the first-line therapy for Hp infection. However,the application of bismuth has some limitations. Aims:To investigate the efficacy of proton pump inhibitor(PPI)-based standard triple therapy combined with teprenone for Hp eradication. Methods:A total of 155 Hp-infected chronic gastritis patients were enrolled from Jan. 2013 to Dec. 2014 at Aerospace Center Hospital,and were randomly assigned into standard triple therapy group,bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group. Patients in standard triple therapy group were given rabeprazole sodium 20 mg + amoxicillin and clavulanate potassium 914 mg +clarithromycin 500 mg bid for 10 days. Patients in bismuth-containing quadruple therapy group were given standard triple therapy combined with bismuth potassium citrate 0. 6 g bid for 10 days. Patients in teprenone-containing quadruple therapy group were given standard triple therapy combined with teprenone 50 mg bid for 10 days. Symptoms of patients were evaluated before and after eradication therapy. Four weeks after the end of therapy,13 C-urea breath test( UBT)was reexamined to assess the status of Hp infection. Results:One hundred and fifty-two patients completed the treatment course. By ITT analysis,the eradication rates of standard triple therapy group,bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group were 69. 8%(37 / 53),86. 5% (45 / 52)and 88. 0% (44 / 50), respectively;by PP analysis,the eradication rates of the three groups were 71. 2%(37 / 52),88. 2% (45 / 51)and 89. 8%(44 / 49),respectively. Eradication rates analyzed by ITT and PP in bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group were significantly higher than those in standard triple therapy group(P <0. 05),but no statistically significant difference was found between these two groups( P > 0. 05). Relieving rates of abdominal pain,abdominal distention and belching in bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group were higher than those in standard triple therapy group,but statistically significant difference was only found in relieving of abdominal pain between teprenone-containing quadruple therapy group and standard triple therapy group(88. 9% vs. 70. 3% ,P < 0. 05). Adverse effects included transient and mild nausea,diarrhea and black stool, etc. Conclusions:Teprenone-containing quadruple regimen are effective for Hp eradication and symptoms relieving with no severe adverse effects,the efficacy is comparable with bismuth-containing quadruple regimen.

BACKGROUND: Urological complication is one of common surgical complications following transplantation and severely threatens renal function, even patient's lives. Urological complications following renal transplantation mainly contain urinary fistula,ureteral obstruction and ureter backflow.OBJECTIVE: To retrospectively analyze the incidence and management of urological complications following kidney transplantation.METHODS: A total of 1 223 patient times following kidney transplants were selected at the Department of Urology, Institute of Surgery Research, Daping Hospital, Third Military Medical University of Chinese PLA from December 1993 to April 2007.According to ureter of donor kidney and the urinary tract of recipients, ureteroneocystostomy was used for urinary tract reconstitution in 948 patient times, and end-to-end ureteroureterostomy in 275 patient times. Urological complications such as urinary fistula, ureteral obstruction and vesicoureteral reflux (VUR) were treated by the different methods on the basis of the different causes, mainly by surgical procedures. Reason of urological complications, surgical management of urologicalcomplications and its clinical outcome, the 3-year survival rate of grafted kidney were measured.RESULTS AND CONCLUSION: In a total of 1 223 patients, urological complications were encountered in 92 cases (7.5%), including 43 cases of urinary fistula (3.5%), 35 ureteral obstruction (2.9%), 14 VUR (1.1%). 35 cases of urinary fistula, 29 ureteral obstruction, 6 VUR were cured by surgical procedures including ureteroureterostomy in 35 patients (50%), revision of ureteroneocystostomy in 18 (25.7%), endourology in 11 (15.7%) and other operation in 6 (9.6%). All recipients with urological complications regained normal graft function except one undoing transplanted nephrectomy due to the pelvis and urteral necrosis. There was no grafted kidney and recipient loss secondary to these complications in the present series. The 3-year survival rate of graft with urological complications and without urological complications did not show significant difference (P > 0.05). These indicated that most of urological complications following kidney transplantation request surgical management, and ureteroureterostomy are frequently used. The long-term graft survival is not affected by a correctly treated urological complication.

Objective To establish the standards for classification of urinary fistula after kidney transplantation. Methods From December 1993 to February 2009, 1313 cases of renal transplanta-tions were operated, out of which 102 cases of urinary fistulas occurred (7.8%). Based on the princi-ple of the urethral injury classification method, we divide urinary fistula into simple and complex clas-ses by the cause, location, and the severity of the disease. Results There were 81 cases (79.4%) of simple urinary fistulas, of those 76 cases were ureteral end necrosis,4 cases were due to ureter blad-der anastomosis suture,1 case was anastomotic problem caused by wound infection. There were 21 ca-ses(20.6%) of complex urinary fistulas, of these 2 cases had fistulas at renal pelvis, 11 cases at ure-ter-bladder interface and 6 cases had ureteral necrosis longer than 2 cm. For the 81 cases urinary fistu-las patients, 34 patients conservative treatments were cured and 47 patients need surgeries. For all complex urinary fistulas need surgeries: 11 cases had surgery once, 5 cases had 2 times, 3 cases had 3 times and 2 cases had 4 times. Among the 2 groups, three patients (2.9%) died of urinary fistulas which led to severe lung infection. Conclusions A "Five Steps Procedure" could be used for diagno-sis and treatment of post renal transplantation fistula. The urinary fistulas are divided into simple and complex types after renal transplantation. This provides a guidance for the best choice of treatment.
