Experience in application of modified sling in treatment of Moderate Stress Urinary Incontinence.

OBJECTIVE: To observe the clinical significance of modified sling in the treatment of moderate stress urinary incontinence (SUI). METHODS: From January 2016 to January 2019, eighty patients with moderate urinary incontinence who were hospitalized in our hospital were randomly divided into two groups. 40 patients in the experimental group underwent modified sling transvaginal tension-free mid-urethral suspension. Modification method of the sling: cut the sling to a remaining length of about 6~7cm, properly connect the barbed sutures (V-LOCK) on both sides of the sling, and insert the urinary incontinence sling from the urethra to the obturator membrane, from the obturator membrane to the thigh. The inner skin area is replaced by the V-LOCK line. The 40 patients in the control group were unmodified ordinary slings. The operation time, the local pain of the inner thigh after the operation, and the improvement of postoperative urinary incontinence symptoms were compared and analyzed between the two groups. RESULTS: Both groups of patients were successfully operated. The operation time was 16.36 minutes in the experimental group and 27.18 minutes in the control group. The difference in operation time between the two groups was statistically significant (p=0.00); the catheter was pulled out on the third day after the operation. One patient in the group had urinary effort, four patients still had urinary incontinence symptoms, the remaining 35 patients had good urinary control (effective rate 87.5%), five patients in the control group still had urinary incontinence, two patients had urinary effort, and the remaining 33 patients had urinary control Good, (effective rate 87.5%), there was no significant difference in surgical effectiveness between the two groups (p=0.53); follow-up for 12 to 36 months, no significant long-term complications occurred, the pain score of the inner thigh of the experimental group was significantly lower than that of the control group ,statistically significant (p=0.04). CONCLUSION: The efficacy of the modified sling in the treatment of moderate SUI is the same as that of the traditional sling, but the operation time is shorter, the operation is simpler, and the local pain is significantly reduced.

[Transurethral resection of the prostate for urinary retention after seed implantation for prostate cancer: report of 2 cases].

OBJECTIVE: To investigate the effect of transurethral resection of the prostate (TURP) in the treatment of urinary retention following seed implantation for prostate cancer. METHODS: We treated 2 cases of urinary retention following seed implantation for prostate cancer by TURP, and analyzed their clinical data. RESULTS: The operations were successful in both of the cases, with mean operation time of 60 min. Postoperative nocturnal urination of the patients averaged 2 times per night as compared with 5 - 6 times per night preoperatively, and their scores on IPSS and quality of life were significantly improved after surgery. CONCLUSION: TURP affords satisfactory results in the treatment of urinary retention following seed implantation for prostate cancer patients.

[A review of spatial epidemiology with malaria surveillance and control in China].

The monitoring and control of malaria depends largely on the spatial analysis technology and mathematical models. Visualization of malaria situation is the most popular way to present how malaria transmits. In this paper, the malaria epidemic situation and the application of spatial epidemiology of malaria in China are summarized, so as to provide the systematic epidemiological information for malaria elimination in China.

[Spatial and temporal characteristics of distribution of Oncomelania hupensis in Eryuan County from 2005 to 2012].

OBJECTIVE: To study the spatial and temporal characteristics of Oncomelania hupensis in Eryuan County, Yunnan Province from 2005 to 2012, so as to provide the scientific evidence for snail surveillance and control. METHODS: Based on the geographic database of O. hupensis snail distribution from 2005 to 2012, the spatial and local autocorrelation analysis and "hot spots" analysis were applied to analyze the spatial and temporal characteristics of the snails. RESULTS: Percent of frames with O. hupensis snails in Eryuan County decreased as a whole from 2005 to 2012. The spatial clustering of global autocorrelation (Moran's I) was increasing from 2007 to 2012 and all Moran's I values showed statistically significance. The local spatial autocorrelation analysis indicated that the number of villages of High-High type of correlation model increased from 2 in 2005 to 7 in 2012, which mainly clustered in plateau canyon areas. The infected snails with High-High type mainly distributed in plateau basin region in 2007. Further "hot spot" analysis found that the living snails gathered in Xinzhuang, Liantie, Xipo and Taiping nearby areas. CONCLUSIONS: The snail distribution in Eryuan has global and local spatial autocorrelations. The number of villages of High-High type of correlation increased. These findings provide the basis for target control of O.hupensis in the future.

[Surveillance of schistosomiasis in a national surveillance site of Yangzhong City, 2005-2009].

A longitudinal survey of schistosomiasis was carried out in Shicheng Village, Yangzhong City, Jiangsu Province, a national schistosomiasis surveillance site, from 2005 to 2009. The results showed that the infection situation of schistosomiasis in residents, and the status of snails, in general, remarkably decreased from 2005 to 2009. However, the snails still existed, so the comprehensive control in marshland and surveillance of infectious sources should be strengthened.

[Impact of different temperatures on development of Anopheles anthropoghagus in Jiangsu Province].

OBJECTIVE: To observe the development and breeding of Anopheles anthropophagus in Jiangsu Province under different temperatures, so as to provide theoretical evidence for malaria epidemiology research and vector control. METHODS: Anopheles anthropophagus was maintained under different temperatures of 16, 19, 22, 25, 28 and 31 degrees C in cultivator, and the development of egg stage, larva, pupal stage and reproductive and vegetative cycle were observed. Then the time of entire developmental cycle of Anopheles anthropophagus at different temperatures was calculated. RESULTS: Anopheles anthropophagus could not complete its entire life cycle under the temperature of 16 degrees C, and it took 30.68, 23.31, 15.46, 13.60 and 12.41 d to finish its life cycle at the temperatures of 19, 22, 25, 28 and 31 degrees C, respectively. CONCLUSIONS: In the temperature range of 16 to 31 degrees C, the developmental cycle of Anopheles anthropophagus in Jiangsu Province will be shortened when the temperature goes up, but whether the result can be extrapolated to other regions still needs to be verified.

[Study on schistosomiasis control measures in mobile boat fishermen. III. Construction and application of regional joint mechanism for schistosomiasis examination and treatment in boatmen].

OBJECTIVE: To construct the regional joint mechanism for schistosomiasis examination and treatment and the examination protocol among mobile boatmen, so as to provide effective measures for control of mobile infectious sources of schistosomiasis in the Yangtze River basin. METHODS: According to the characteristics of the cargo frequent mobility of ships with fixed anchor points, the health, maritime and transport sections were jointly cooperated to set up sites for schistosomiasis examination and treatment in ship locks, wharfs and harbors. The infection of schistosomiasis was detected by means of rapid immunological screening and stool examination, and the regional joint mechanism was constructed. The sero-positives were traced for further parasitological examinations and treatment by using the regional joint network for schistosomiasis examination and treatment. The schistosome infections in boatmen were analyzed and compared between different examination and treatment sites and among different navigation coverage. RESULTS: A total of 16 sites for examination and treatment of schistosomiasis, including 5 fixed sites and 11 mobile sites, were set up in 12 townships of 6 districts (counties) of Yangzhou City. During a period between June and August, the examination of schistosomiasis was conducted in 40 sites, and of the 1 225 boatmen from 967 boats detected, 19 cases were sero-positive, with a positive rate of 1.55%. Among the 14 sero-positives examined, no stool positive patients were found. Among the 1 225 boatmen detected, 820 were from fixed sites and 405 from mobile sites, and 4 and 15 cases were found, respectively, with positive rates of 0.49% and 3.70%, respectively, and the sero-positive rate was higher in mobile sites and that in fixed sites. A total of 898 boatmen from the Yangtze River basin and 305 from the local inland rivers were examined, and 3 and 16 sero-positive cases were detected, respectively, with positive rates of 0.33% and 5.25%, respectively, and the sero-positive rate was significantly higher in the boatmen from the local inland rivers than that from the Yangtze River basin. CONCLUSION: Regional joint mechanism is an effective strategy for examination and treatment of schistosomiasis among mobile boatmen, which provides a new approach to control mobile infectious sources of schistosomiasis in the Yangtze River basin.
