Objective To investigate the changes of plasma levels of glucagon in cirrhotic patients and its effect in the pathogenesis of portal hemodynamics.Methods Plasma levels of glueagon were measured by radioimmunoassay(RIA)in 42 patients with liver cirrhosis and 20 healthy controls.The max diameters,mean flow velocity,flow rate of the portal vein trunks(PV)and splenic veins(SV)were detected by Color Doppler Ultrasound.Results Plasma levels of glucagon in cir- rhotic patients were significantly higher than those in controls and were increased with the severity of hepatic function im- pairment as assessed by Child-Pugh grade.Patients with ascites showed signifieanthigher plasma glucagon levels than those without ascites.Plasma levels of glueagon were positively correlated with portal vein diameters,splenic vein diame- ters and splenic vein flows.Conclusion The increase of plasma glucagon levels reflects,in part,the severity of impair- ment of hepaticfunction.In addition,it may contribute to the pathogenesis of portal hypertension.

Objective To explore the efficacy and prognostic factors of postoperative intensity?modulated radiotherapy ( IMRT) with or without chemotherapy in rectal cancer. Methods A retrospective analysis was performed on the clinical data of 218 patients with rectal cancer, who underwent postoperative IMRT in our hospital from January 2009 to December 2013. The Kaplan?Meier method was used to calculate survival rate;the log?rank test was used for survival difference analysis and univariate prognostic analysis;the Cox regression model was used for multivariate prognostic analysis. Results The follow?up rate was 97. 7%. The 1?and 3?year overall survival rates were 90. 8% and 75. 2%, respectively, the 1?and 3?year disease?free survival rates were 85. 3% and 70. 5%, respectively, and the 1?and 3?year locoregional recurrence?free survival rates were 96. 7% and 88. 1%, respectively. The incidence of grade 3?4 acute adverse reactions was 28. 4%, mainly manifested as leukopenia ( 13. 8%) and diarrhea ( 11. 0%) . Univariate prognostic analysis showed that preoperative carcinoembryonic antigen ( CEA) and CA199 levels, maximum tumor diameter, tumor location, degree of differentiation, depth of tumor invasion, number of lymph node metastases, TNM stage, perineural invasion, surgical procedure, total mesorectal excision, preoperative bowel obstruction, and preoperative anemia were the predictors of survival ( P=0. 006, 0. 000, 0. 000, 0. 017, 0. 000, 0. 016, 0. 000,0. 011,0. 001,0. 006,0. 037 and 0. 010) . Multivariate prognostic analysis showed that preoperative CEA level, tumor location, TNM stage, preoperative bowel obstruction, and preoperative anemia were the predictors of survival ( P=0. 000,0. 000,0. 000,0. 001 and 0. 001) . Conclusions Postoperative IMRT with or without chemotherapy is an effective method for rectal cancer with mild adverse reactions and high compliance. Preoperative CEA level, tumor position, TNM stage, preoperative bowel obstruction, and preoperative anemia are independent prognostic factors for the overall survival.

Objective To investigate the clinical curative result of the new method of postermedial deepen of the fibular groove in the treatment of chronic peroneal tendon subluxation.Methods From March 2006 to October 2012,21 patients (15 male,6 female) with chronic peroneal tendon subluxation via a novel method of postermedial deepen of the fibular groove.In this group:Ⅰ grade 5 cases;Ⅱ grade 9 cases;Ⅲ grade 5 cases;Ⅳ grade 2 cases.All patients were followed up for at least 24 months.The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale score and visual analogue score (VAS) were used to evaluate the clinical outcomes.Operation time,time to heal and complications were also recorded.Results The average operation time was 50 minutes (30-70 minutes).The blood loss was 30-60 ml,average 40 ml.All incisions healed after operation,no case of incision infection,skin necrosis and sural nerve,vascular injuryed.Mean AOFAS score was significantly increased from (55.2±7.1) preoperative to (93.6±5.6) postoperative.15 patients with excellent,good for 1 cases.The excellent and good rate was 100％ (16/16).VAS score by an average of (5.3±2.1) points down to (1.2±1.1) points postperative.All the patients can wear normal shoes postoperative,waking with normal gait.No patients had peroneal tendon tenosynovitis,tendon adhesion,fracture of lateral malleolus and other serious complications,no dislocation recurrent,strength of the peroneal muscle returns to normal.Conclusion The novel method of postermedial deepen of the fibular groove in the treatment of chronic peroneal tendon subluxation was safe and effective for ankle instability with a relatively short time.

To evaluate the application of intracavitary three-dimensional ultrasonography in the diagnosis of polycystic ovary syndrome ( PCOS). The three-dimensional volumes of ovary were measured by intracavitary ultrasonography in 40 PCOS patients and 40 normal controls. The diagnostic value of parameters derived from three-dimensional ultrasonography was evaluated by using the receiver operating characteristic (ROC) curve. The ovarian volume, stromal volume, and the stromal/total volume ratio in PCOS group were significantly higher than those in control group (both P ＜ 0. 05 ) ; the area under ROC curve ( AUC ) of them were 0. 876, 0. 926, 0. 886 respectively. Among these parameters, stromal volume had the highest diagnostic value for PCOS, the cut-off value of which was 7.52 cm3 with a sensitivity of 88% and a specificity of 90%. Volume parameters of ovary measured by intracavitary three-dimensional ultrasonography can offer quantitative information for the diagnosis of PCOS.

Objective To study dIe ESBLs and plasmid-mediated AmpC enzymes in E.Coli and Klebsiella spp. with CLSI ESBL-screening test positive,confirmation test negative but cefepime susceptible.Methods Antimierobial susceptibility testing were performed by Kirby-Bauer(K-B)method.The genes encoding ESBLs and plasmid-mediated AmpC enzymes were detected by PCR Transfer of ESBLs or plagmid-mediated AmpC resistance was studied by conjugation experiments.The homology of donor (E.coli),recipient(E.coli J53)and their transconjugants were analyzed by ERIC-PCR DNA fingerprints of E.coli and Klebsiella pneumoniae were analyzed by PFGE as recommended bv PulseNet protocoL Results Of 18 isolates from Huashan Hospital,11 were E.coli.6 were Klebsiella pneumoniae and 1 was Klebsiella oxytoca.Antimicrobial susceptibility testing indicated all of 18 isolates were positive on the CLSI ESBL screening test but negative on the confirmation test.and all of isolates were susceptible to cefepime(a zoneof-inhibition diameter of≥18 mm wag considered to indicate susceptible).PCR results indicated that 9 of the 11 E.coli isolates predued CMY-2 AmpC enzyme.TEM,SHV,CTX-M,PER,VEB or SFO type β-lactamages were not identified.Of 6 Klebsiella pneumoniae isolates.5 were DHA-1 AmpC-producing strains.4 of the 5 DHA-1 AmpC-producing strains were coexistence of broad-speetrumβ-lactamaae or extended-spectrumβ-lactamase.including two producing SHV-11 and two producing CTX-M-14 and SHV-62 type ESBL respectively.One Klebsiella oxytoca wag also DHA-1 AmpC producing strain.Conjugation experiments indicated that both ESBLs and AmpC enzymes could be transfefred from donor to recipient.PFGE indicated that the DNA fingerprints of K.pneumoniae were difierent but seven CMY-2 AmpC-producing E.coli isolates from general surgieal ward were similar.Concluslons The main mechanism of antibiotic resistance in CLSI ESBLs-screening test-positive but eefepime.susceptible E.coli and KIebsiellaspp.is production of plagmid-mediated AmpC enzymes.Some strains produce both AmpC enzyme and ESBLs.Such strains should be reported as resistant to cefepime.The results suggest that laboratories should routinely conduct research on the ESBLs and plnsmid.mediated AmpC enzymes in Enterobacteriaceae in order to report antimicrobial susceptibility testing results more correcdy.

Objective To evaluate the significance of weight-bearing lateral radiographs in evaluation of malunited frac-tures of the ankle. Methods 17 patients with malunited fractures of the ankle were treated by different reconstructive operations be-tween March 2010 and October 2012, including 9 females and 8 males, aged from 17 to 64 years. According to the Takakura classifi-cation of ankle arthritis, there were 7 patients in grade 1, 4 in grade 2 and 6 in grade 3. Simple open reduction and internal fixation were performed in 5 patients, supramalleolar tibial osteotomy in 5, lengthening osteotomy of the fibula in 2, supramalleolar tibial and fibular osteotomy in 5. Tibiofibular clear space on the anteroposterior radiograph. Medial clear space, tibiofibular clear space and tib-iofibular overlap on ankle mortise radiographs were compared preoperatively and at last follow-up. Tibial lateral surface angle (TLS), the offset of the center of talar rotation from the tibial axis, and the displacement of tibiotalar articular surface center on weight-bear-ing lateral X-ray were also compared preoperatively and at last follow-up. AOFAS score was used to evaluate the function of the ankle. Results The duration of follow-up was 9 to 32 months. Bone healing was observed in all patients, and the average healing time was 11 to 14 weeks. Ankle joint degeneration grade had no exacerbation. The medial clear space, tibiofibular clear space and tibiofibular overlap had no significant difference between the pre and postoperative. Statistically significant change was seen postoperatively in the values of TLS (76.9°±4.1° vs 80.9°±5.2°). The offset of the center of rotation from the tibial axis and the displacement of tibiotalar articular surface center were changed from 10.8 ± 2.1 mm to 2.0 ± 0.5 mm and 4.5 ± 1.5 mm to 2.2 ± 1.0 mm, respectively. The average AOFAS score was improved from 45.7 ± 15.9 points preoperatively to 82.0 ± 9.9 points postoperatively. Conclusion Weight-bearing lateral radiographs can be used to judge the ankle restoration. Even if the mortise radiograph had relative good realignment, it may ap-pear obvious deformity on lateral radiographs. Good reduction of lateral radiographs requires that the mid axis of the tibia should pass through the center of talar rotation and tibiotalar articular surface be parallel on the lateral radiograph.

Objective To evaluate the efficacy of using dual laser system in off clamp nephronsparing surgery.Methods We used dual laser system in the patients who underwent off-clamp NSS between Jan 2016 and Apr 2016 in our institution.There were 16 males and 8 females with average age of 49 years.Mean tumor size was 1.9 cm (range 0.8-3.2 cm).The mean R.E.N.A.L.score was 3.8 (range 3-6).The mean Zhongshan score was 3.5(range 3-5).The mean ZⅡ(zero ischemia index)was 1.6(range 1-4).The Evolve Dual (980 nm/1 470 nm) laser system set at 60 W in continuous mode was used.Results Offclamp NSS was successfully performed in 22 patients except for renal artery occlusion in 2 case.Mean operative time was 74 min(range 50-100 min);The average estimated blood loss was 52.9 ml(range 10-200 ml);Mean postoperative drainage was 65.4 ml(range 20-150ml);Mean postoperative hospital stay was 5.2 days (range:4-7days).No severe post-operative complication was found.The mean pre-and postoperative serum creatinine levels were 76.2 μmol/L(range:48-112μ mol/L) and 81.5μ mol/L(range:54-122 μ mol/L) with no significant difference(P ＞0.05).The postoperative pathology indicated that 20 cases of clear cell carcinomas,3 cases of chromophobe renal cell carcinomas,one case of papillary carcinoma.Conclusions Dual laser system can be used in off clamp nephron-sparing surgery safely and effectively.
