目的 探讨45°半坐卧位对良性前列腺增生患者膀胱压力容积测定的影响。方法 按照入选标准和排除标准选取临床确诊为良性前列腺增生(Benign Prostatic Hyperplasia,BPH)患者。按照二阶段交叉设计的方法将入选患者随机分入A、B两组。A组患者先进行45°半坐卧位膀胱压力容积测定(Cystometry,CMG),再进行平卧位CMG,B组患者先进行平卧位CMG,再进行45°半坐卧位CMG。统计以下CMG参数:膀胱初始感觉容量、膀胱初始尿意容量、膀胱最大容量及逼尿肌过度活动发生率。结果 与平卧位相比,45°半坐卧位对膀胱初始感觉容量、膀胱初始尿意容量、膀胱最大容量的测定无影响,且能提高逼尿肌过度活动的检出率(45°半坐卧位37.21% vs.平卧位11.63%,P=0.006)。结论 45°半坐卧位能代替平卧位作为CMG的检查体位。

Objective To investigate influence of 45 degree semi-reclining position in cystometry in patients with benign prostatic hyPerplasia(BPH). Methods Patients with BPH were enrolled according to the inclusion and exclusion criteria. They were divided into two groups randomly by two stage cross-over design. Group A took the 45 degree semi-reclining position firstly then supine position, while group B used a reverse order.CMG parameters included volume of first sensation to void (FS), volume of first urge to void (FU), maximum cystometric capacity (MCC) and detrusor overactivity(DO). Results 45 degree semi-reclining position had no effect on volume of FS、volume of FU、MCC, and could increase the detection rate of DO(45 degree semi-reclining Position 37.21% vs. supine 11.63%,P=0.006). Conclusion 45 degree semi-reclining position may be used as a substitution for supine in FC.

目的 探讨妇女阴道健康状况及阴道分泌物清洁度、线索细胞及唾液酸酶法检测细菌性阴道病(BV)的相关性。方法 随机抽取2013年4月—2014年6月本院妇科疑似细菌性阴道病患者标本835例,分别采用生理盐水直接涂片及分泌物直接涂片进行革兰氏染色两者相结合检查清洁度、线索细胞;唾液酸酶法检测BV。结果 清洁度Ⅰ～Ⅱ占27.55%,BV阳性率为2.40%,线索细胞检出率1.32%;清洁度Ⅲ～Ⅳ占72.45%,病原菌阳性率为46.23%,其中BV阳性率为30.55%,线索细胞检出率为23.48%。结论 清洁度异常率比正常率偏高;清洁度正常不一定没有细菌性阴道病; BV的出现严重威胁妇女身体健康,正确的诊断有重要意义,唾液酸酶法检测BV虽有快速、操作简单、显色结果易判断,但温度、时间、取材问题等受多种因素影响。

Objective To explore the correlation between the health of women's vagina and vaginal cleanness, clue cells and bacterial vaginosis(BV)which is tested by the sialic acid enzymatic method. Methods Randomly select 835 suspected cases of bacterial vaginosis in our hospital gynecology department in April 2013-June 2014. Every case was respectively done saline direct smear and vaginal secretion direct smear gram staining to check vaginal cleanness and clue cells. BV is tested by sialic acid enzymatic method. Results The cleanness of I-II accounted for 27.55%, BV positive rate was 2.40%, the positive rate of clue cells was 1.32%;the cleanness of degree III-IV accounted for 72.45%, the positive rate of pathogenic bacteria was 46.23%, the positive rate of BV was 30.55%, the positive rate of clue cells leads to 23.48%. Conclusion The rate of abnormal vaginal cleanness is higher than the normal.The nomal vaginal cleaness does not show no bacterial vaginosis. The emergence of BV seriously affects women's health, so the correct diagnosis is of great importance. Although the of the saliva acid enzyme to test BV is fast, operates easily and the color results are easily to be judged, but it can be influenced by other factors such as temperature, time, materials issues.

目的 分析经直肠彩超引导下不同前列腺穿刺方式的阳性率及其相关因素,探讨安全的穿刺方案。方法 回顾性分析接受经直肠彩超引导下前列腺穿刺的701例患者临床资料,所有患者均接受系统性13点穿刺活检,并假设13点穿刺中减少前列腺中线3个穿刺点为10点穿刺术式,加之标准的6点穿刺术式。比较上述穿刺术式的阳性率,分析T-PSA、前列腺体积、PSA体积密度(PSAD)、有无前列腺结节对穿刺阳性率的影响。结果 随前列腺穿刺针数的增加,活检阳性率增高。同一穿刺方式,不同T-PSA组间、不同前列腺体积组、不同PSAD组阳性率有差异。T-PSA>100 ng/mL时,三种穿刺方式的阳性率无差异;T-PSA<100 ng/mL时,6点穿刺法阳性率较低,而10点穿刺、13点穿刺阳性率无差异。前列腺体积>80 mL时,不同穿刺法阳性率有差异。PSAD<0.5 ng/mL²时,10点、13点穿刺阳性率无差异。结论 前列腺穿刺活检阳性率随穿刺针数增多而增加,可根据PSA水平、前列腺体积、PSAD选择个体化穿刺方案。

Objective Exploring the impact of establishing a tracking and management model for important abnormal results of health check ups based on quality control circle activities on improving telephone follow-up rates. Methods A total of 328 subjects with important abnormal results in Health Management Center of Sun Yat-sen Memorial Hospital of Sun Yat sen University from May 2022 to April 2023 were selected. The quality control circle activity group was set and the tracking management mode was carried out. The post intervention period was from November 2022 to April 2023, during which intervention measures 1-4 and comprehensive implementation measures were implemented for different samples. The number of successful follow-up after 1 month of follow-up was analyzed. Changes in the comprehensive ability of the circle staff before and after the intervention and the patients’ satisfaction with the health management center were compared. Results The telephone follow-up rate after intervention 1 was 85. 02%, 88. 59% after intervention 2,90. 23% after intervention 3,95. 27% after intervention 4 and 95. 80% after all intervention,which was higher than 75. 91% before intervention implementation. Among the single intervention individuals, the re-visit rate was 84. 34%（210/249）, and after the comprehensive implementation of measures, the re-visit rate among the successfully intervened individuals was 94. 74%（216/228）. After the intervention,the problem solving ability,responsibility, communication and coordination,team cohesion, enthusiasm,quality control techniques,self-confidence,and sense of harmony all significantly increased（P<0. 05）. The patient satisfaction rate before intervention was 85. 37%, and after intervention it was 87. 80%. The satisfaction rate increased after intervention, and the difference was statistically significant（P<0. 05）. Conclusions Through the quality control circle activities, the telephone follow-up rate of important abnormal results is significantly improved,which is conducive to improving the service quality and service capacity of physical examination institutions,is conducive to the early detection and early intervention of diseases.
