ABSTRACT
Objective To compare the performance of Mandarin screening version of hearing handicap inven-tory in elderly (HHIE-S)and the single question of hearing loss in the hearing screening in the old adults.Methods A total of 570 participants,aged from 50~85 years,of native Mandarin speakers were tested with standard pure tone audiometry (PTA),HHIE-S and single questionAre you now having difficulty in hearing?.HHIE-S>8 was taken as an indicator of hearing handicap.Sensitivity,specificity,negative predictive values and positive predic-tive values of both HHIE-S and single question inquiry when 0.5~4 kHz PTA average > 25 dB,>40 dB and >60 dB were compared.Results The prevalence was 83.9% (478)measured by PTA.The prevalence was 55.3%and 52.5% for HHIE-S and positive answer for single question,respectively.The sensitivity of HHIE-S when the participants grouped with 0.5~4 kHz PTA average > 25 dB,>40 dB and > 60 dB was 61%,85% and 96%, respectively,whereas the sensitivity of single question of the above 3 conditions was 58%,81% and 100%,respec-tively.The specificity of HHIE-S decreased with greater hearing loss.It was 72%,88% and 47% respectively for HHIE-S and 75%,61% and 50% for the single question.There was no significant difference either for sensitivity and specificity between the HHIE-S and the single question.Conclusion Both the Mandarin version of HHIE-S and single question are effective in the hearing screening of old adults.Depending on the purpose and availability of resources,one or both of them can be adopted.
ABSTRACT
Objective To investigate the expression of β-catenin and PCNA,and its relationship with clinical parameters and prognosis.Methods Tissue microarray technology and immunohistochemical method were used to detect the expression of β-catenin and PCNA in gastric carcinoma and normal tissue collected from January 2000 to December 2006.Data were analyzed by SPSS 19.0.Results The percentage of expression of β-catenin and PCNA in gastric carcinoma is 96.7％,99.2％,respectively,and higher than the normal gastric tissue (x2 =41.082,P =0;x2 =97.692,P =0).ROC curve was used to find that PCNA was better than β-catenin to discriminate gastric carcinoma from normal gastric tissue in sensitivity,specificity,coincidence rate(84.4％,87.5％,84.6％).The expression of β-catenin is related to lymph node metastasis in gastric cancer (x2 =6.107,P =0.04).The expression of PCNA is related to pathological type (x2 =9.71,P =0.02).The expression of β-catenin and PCNA in gastric carcinoma were positively correlated (r =0.24,P =0.005).Multivariate analysis showed that TNM staging and both positive β-catenin and PCNA were independent factors impacting on the overall survival rate of patient with gastric cancer.Conclusions The expression of β-catenin and PCNA in gastric carcinoma is signifrcandy high.PCNA is more important than β-catenin in discriminating gastric carcinoma from normal gastric tissue.Combined detection of the two kinds of protein have some clinical significance in predicting the prognosis of patients with early gastric cancer.
ABSTRACT
Objective To evaluate the safety and efficacy of one-stage endoscopic sphincterotomy plus laparoscopic cholecystectomy for the treatment of patients who have concurrent gallstones and CBD stones.Methods We conducted a prospective study from Mar 2008 to Nov 2011 in our department.A total of 63 consecutive patients of concurrent gallstones and CBD stones were included and divided into two groups:31 patients in test group first underwent ERCP and EST to remove CBD stones,and then during the same general anesthesia underwent laparoscopic cholecystectomy (LC) ; while 32 patients in control group first underwent ERCP and ES,and then LC 3-5 days later.Results The stone clearance rate in test group and control group were 96.9％ and 96.7％ (P ＞ 0.05),respectively.The postoperative lung infection rate in the test group and the control group were 7.1％ and 16.1％ (P ＜0.05),respectively.The length of hospital stay (LOS) of the two groups was (7.5 ± 1.7) days and (12.6 ±2.5) days,respectively (P ＜ 0.05).The total expense of hospitalization was (￥) (2 356 ± 126) and (￥) (37 056 ± 152),respectively (P ＜ 0.05).Conclusions One-stage laparoendoscopic management of patients with concurrent gallstones and CBD stones is safe,effective and more economic approach than two-stage treatment for patients suffering from concurrent gall stone and choledocholithiasis.
ABSTRACT
ObjectiveTo investigate the etiology, diagnosis and choice of treatment for massive hemobilia. MethodsA retrospective analysis was made on the clinical data of 20 patients with massive hemobilia treated from August 1998 to August 2008. ResultsInitially conservative therapy was used on 20 patients and bleeding stopped in 4 patients. For the seven patients who were treated with hepatic artery angiography and embolization, bleeding stopped in 6 patients. 10 patients were treated by operation and bleeding stopped in all these patients. No patient died in this series. ConclusionsHepatic artery angiography and embolization should be used to treat patients with massive hemobilia. Surgery should be offered if conservative therapy and hepatic artery embolization fail.
ABSTRACT
Objective In this retrospective study, we analyzed the magnetic resonance imaging (MRI)and computed tomography(CT)scans of patients with prostate cancer to investigate the relationship between the apex of prostate and the anatomic structures visible in CT, and to provide evidence for localizing the prostatic apex in radiation treatment planning. Methods MRI and CT scans from 108 patients with prostate cancer were analyzed to measure the distance between the prostatic apex and the bottom of ischial tuberosities,the bottom of obturator foramen, the bottom of pubic symphysis and the bulb of the penis. The volume of prostate was calculated and the relationship between the size of the prostate and the localization of the prostatic apex was analyzed. Results The prostatic apex is located 13. 1 mm ±3. 3 mm superior to the bulb of the penis, 11.0 mm ± 5.4 mm superior to the bottom of obturator foramen, 31.3 mm ± 5.5 mm superior to the bottom of ischial tuberosities, and 7. 1 mm ± 4. 7 mm superior to the bottom of obturator foramen. There was no correlation between the size of prostate and the localization of the prostatic apex(R =0. 07、-0. 33, all P ＞ 0. 05). Conclusions Ninety-five percent of patients had a prostatic apex that is above the bulb of the penis 6 mm, and 100% of patients had a prostatic apex that is above the bottom of obturator foramen.
ABSTRACT
Objective To study the function of Contour stapler in the sphincter-preserving surgery in 121 cases with low rectal cancer. Methods One hundred and twenty-one cases enrolled were divided into 2 groups randomly and accepted Contour or other kinds of staplers after operation respectively. Further comparison were performed on the rate of sphincter-preserving,anastomosis stricture and leakage,infection of incision and stool frequency between two groups. Results We found no significant differences in the comparison of rate of anastomosis stricture or leakage,stool frequency,but the Contour group had significant higher rate of sphincter-preserving (98. 3%)than other stapler group(68. 9%),and lower rate of infection of incision(3.94%)than control(11.9%)(P ＜0. 05 respectively). Conclusions It is secure,reliable and practical to use Contour stapler in operation on low rectal cancer,which can increase the opportunity of sphincter-preserving,decrease the the rate of infection of incision.
ABSTRACT
Objective To observe the fixity of 125I seed after implantation in parotid region. Methods Ten patients treated with 125I seed interstitial brachytherapy in parotid were randomly selected. Within one week after the treatment, two plane radiographs were taken by radiotherapy simulator and 125I seed was counted. All plane dosimetry analysis were performed by treatment planning system. The areas surrounded by 50%, 100% and 150% of prescription dose curve and dose equality index were calculated. Two months after the treatment, the same examination were repeated and were compared with t test. Results The number of seeds was equal in two examination. There were no signifieant differences in two examinations either for the areas surrounded by 50%, 100% and 150% of prescription dose curve or for the dose equality index. Conclusions The position of 125I seed after implantation in parotid region is quite fixable, which can ensure the curative effect.
