Objective To evaluate the effect of cholecystokinin receptor antagonist proglumide on the pancreatic function of post-ERCP. Methods The frequency and mortality of acute pancreatitis of post-ERCP, and the plasma contents of cholecystokinin-octapeptide(CCK-OP) and amylase were compared among control group(group C),octreotide treatment group(group O) and proglumide treatment group(group P). Results The frequency of acute pancreatitis of post-ERCP in group C was 13.6%(3/20), which was significantly higher than that in Group O(5%,1/20) and group P (4.0%,1/25)(P0.05). The contents of plasma CCK-OP were significantly lower in group P than those in groups O and C 4h after ERCP (P0.05). Conclusion Proglumide could inhibit the action of cholecystokinin-octapeptide, and decreas the hyperamylasemia and the frequency of pancreatitis of post-ERCP as octreotide.

Objective To study the morphologic and structural changes of the pelvic floor and corresponding visceras in patients with outlet obstructive constipation (OOC). Methods We used simultaneous pelvicography and colpocystodefecography (PCCD), including pelvicography, vaginal opacification, voiding cystography and defecography in 38 patients with OCC and 12 healthy volunteers. Anorectal angle, the level of perineum, and bladder were measured. Results Internal rectal prolapse (IRP) in 37 cases, rectocele (RC) in 5 cases and spastic pelvic floor syndrome (SPFS) in 5 cases were diagnosed by PCCD. While common physical examination alone detected only 12 cases, 4 RC cases and one SPFS case, which were confirmed by PCCD. Moreover, PCCD found 9 cases of pelvic floor hernia or peritoneoceles, 6 cases of cystoceles, 3 cases of descending perineum syndromes, and 10 cases of uterine prolapses. Compared with controls, OOC patients had a larger anorectal angle during defecation, abnormal descending of perineum at rest and defecation, and a deep pouch of Douglas during defecation. Some patients with urinary system symptoms have an abnormal descent of bladder during rest and defecation. Conclusion PCCD has a higher detection rate than common physical examination in diagnosing IRP and RC, and provides information for diagnosis of pelvic floor hernia or peritoneocele, cystocele or uterine prolapse. PCCD helps in the selection of a proper surgical procedure for OOC patients.

Objective To classify tibial plateau fractures based on the analysis of the morphology and injury mechanisms of 200 cases of tibial plateau feature.Methods We collected the X-ray and CT images of 200 consecutive cases of tibial plateau fracture in i99 patients who had been treated at our department from January 2010 to April 2011.They were 134 males and 65 females,from 15 to 77 years of age (average,45.7 years).According to the Schatzker classification,9 cases were type Ⅰ (4.5％),105 type Ⅱ (52.5％),19type Ⅳ (9.5％),37type Ⅴ (18.5％),30type Ⅵ (15.0％),and none type m.The fracture morphology and injury mechanism of each case were analyzed to propose a new classification system.Results Fractures of tibial plateau can be classified into the following five types:(a) Lateral condylar fracture and valgus injury (100 cases,50％).The injury mechanism is the axial force on the valgus and extended knee joint.(b) Fracture-dislocation injury (24 cases,12.0％).This type includes typical Schatzker type Ⅳ,and some cases of Schatzker type Ⅵ associated with lateral subluxation.Its mechanism is a compound force of valgus,varus,rotational and axial stresses.The rotational force is the key factor leading to subluxation of the knee joint.(c) Double-condylar fracture (40 cases,20.0％).This type is caused by an axial force on the extended knee,including Schatzker type Ⅴ and some cases of Schatzker type Ⅵ not associated with knee subluxation.(d) Posterior condylar fracture and flexion injury (32 cases,16.0％).This type only involves the posterior condylar plateau,and is caused by an axial force on the flexed knee.Based on the morphology,posterior condylar fractures can be further divided into three subtypes:simple split of posteromedial condyle,simple collapse of posterolateral condyle,and a combination of the two.(e) Frontal plateau compression fracture and hyperextension injury (4 cases,2.0％).This type is caused by an axial force on the hyper-extended knee.It is characterized by significant compression of the anterior plateau and intact posterior plateau.Conclusion Based on the morphological features and injury mechanisms,tibial plateau fractures can be classified into 5 types:lateral condylar fracture,fracture-dislocation injury,double-condylar fracture,posterior condylar fracture,and frontal plateau compression fracture.

Objective:To explore the feasibility and therapeutic efficacy of using the Henry approach to expose and place a metaphyseal bone plate laterally to fixate a proximal radial shaft fracture.Methods:A retrospective analysis was done of the 5 proximal radial shaft fractures (defined as the fracture involving the extent between the radial tuberosity to the insertion of the pronator teres) which had been treated from April 2018 to June 2019 at Department of Traumatology and Orthopedics, Beijing Jishuitan Hospital through the Henry approach to place a metaphyseal plate laterally to the radius for fixation. There were 2 males and 3 females, aged from 16 to 59 years (average, 41.4 years), with 3 cases on the left side and 2 cases on the right side. The imaging data, fracture healing time, forearm pronation-supination, and visual analogue scale (VAS) of the patients were regularly followed up; the therapeutic efficacy was evaluated at the last follow-up using Quick Disabilities of the Arm, Shoulder, and Hand (Quick-DASH), Anderson and Grace-Eversmann evaluations.Results:The 5 patients were followed up for 7 to 16 months (average, 10.6 months). Their fracture healing time averaged 4.6 months, elbow flexion 146°, extension -2°, pronation 77°, and supination 88°. In postoperative VAS, 4 cases scored a 0 point and one case 1 point. At the last follow-up, their Quick-DASH scores averaged 4.1 points; by the Anderson evaluation, 5 cases were excellent; by the Grace-Eversmann evaluation, 4 cases were excellent and one case was good. No postoperative complication was observed.Conclusion:It is an effective treatment of proximal radial shaft fracture to use the Henry approach to expose and place a 3.5mm metaphyseal plate laterally to the radius for fixation.

Objective To evaluate operative effect on internal rectal prolapse. Methods Sixty-two patients with internal rectal prolapse who underwent operation were studied by retrospectively analyzing the treatment and followed up results. Results The total success rate of surgical treatment for internal rectal prolapse is 73%. The rate of symptoms improvement as difficulty in defecation,anal aboating, incomplete defecation,asistation with fingers,and defecating dependent on laxatives were 77%,80%,71%,86%,97% respectively. Conclusion the operative indications of internal rectal prolapse should be strictly controlled. Only those who received standard conservative treatment and failed to improve should be a candidate for surgery.

Objective To observe the effect of somatostatin (SST) on the expression of metalloproteinase-2(MMP-2) and tissue inhibitor matrix metalloproteinase-2(TIMP-2) of implanted tumor in nude mice after partial hepatectomy.Method Nude mice were divided into group A(n=10) implanted by human hepatocellular carcinoma(HCC),group B(n=10, partial hepatectomy) and C(n=10,HCC implantation after liver resection). SST(250 ?g/kg,b.i.d) was given intraperitoneally in group C. Mice were sacrificed on 35th d, tumor was measured, the expression of MVD.MMP-2 and TIMP-2 was detected by immunochemical staining and quantitative image computer-analysis. Results In group B, the weight and volume and expression of MVD.MMP-2 of tumor tissue was markedly incressed than in group A(P

Objective:To analyze the clinical parameters of the patients with femoral neck fracture such as general condition,therapy method,hospitalized expense so as to provide more effective management plan for the clinical work.Methods:The patients with femoral neck fracture above 50 years who received in-patient treatment from 2008 January to 2012 December were admitted into this study.We collected and analyzed the information,such as age,chronic medical disease,therapy method,hospitalized duration and expense and so on.Results:There were 1 794 femoral neck fracture patients above 50 years (male/female=1/2.06)in our hospital in recent 5 years and the annual average rate of increase was 7.3%. The average age of the patients was (69.9 ±10.7)years and the annual average rate of increase was 0.6%.The chronic medical disease diagnosis ratio was 55.0%.The average waiting time for operation was (6.8 ±4.2)days and the average hospitalized duration was (12.9 ±4.9)days which showed down-ward trend in recent years. The most popular operations were cannulated screw internal fixation (41.8%)and artificial femoral head replacement (34.1%).In the study,146 cases (7.9%)received nonsurgical treatment which showed downward trend.The average hospitalized expense was (35 075 .7 ± 1 1 343.2)yuan which showed no obvious change in recent years.The cost for the females was more than that for the males.The expense for hemiarthroplasty and total hip arthroplasty increased while that for cannulated screw internal fixation decreased gradually.Conclusion:The cannulated screw internal fixa-tion and artificial femoral head replacement were the most important operations for the patients with femo-ral neck fracture.The number and the average age of the patients were on the rise while the expense showed no obvious change in recent years.
