Objective To evaluate clinical efficacy of extracorporeal shock wave lithotripsy (ESWL) for treating patients with double J (DJ) stent extubation difficulties.Methods A retrospective analysis were conducted from July 1999 to December 2013,total 30 cases (18 male and 12 female) were accepted the ESWL therapy for treating the DJ extubation difficult due to the stone scales surface.The average age in those patients was 46 years (range 24 to 83 years).The average duration of DJ stents indwelling was 8.3 months (range 1.5 to 36.0 months).There were 10 cases with single stone and 20 cases with multiple stones.The distribution of stone location included left kidney in 14 cases,right kidney in 6 cases,left ureter in 3 cases and right ureter in 7 cases.The ureteral stone scales around the DJ stent showed tubular distribution.The distribution of imaging characteristic included kidney stones around the DJ stent joint in 20 cases and surface coarse in 10 cases.The diameter of the stone ranged from 0.7 to 3.2 cm (mean 1.8 cm).All the 30 cases were treated by ESWL with the 2 000-3 300 times frequency (mean 2 800 times).Treatment voltage was 4-8 KV.Results Gravel time ranged from 40 to 70 min (mean 45 min).No intraoperative and postoperative complications occurred.Their DJ stents were easily extubated immediately after ESWL.One week after ESWL,all the patients reported the flushing of the stone.Conclusion ESWL is a simple,convenient and efficacy way to solve the DJ stent extubation difficulties due to the scales surface.

Objective To explore the clinical effect of extracorporeal shock wave lithotripsy (ESWL) for the treatment of horseshoe kidney stones.Methods A total of 42 cases of horseshoe kidney stones from March 1987 to January 2015 were enrolled.Among them,33 cases were male and 9 cases were female.Their age range was 19 to 71 years,average age was 42 years old.25 cases got left renal pelvis stone,17 cases were on the right renal pelvis side.The diameter range of stone was 0.4-3.7 cm,the average was 1.8cm.ESWL was applied to treat whole group.The prone position was used to removing calculus.The frequency of treatment was 2000-2700 times,with an average of 2500 times;the treatment voltage was 4-7KV.The gravel time of the treatment was 30-45min,the average was 35min.Results One time for ESWL was 29 cases,two times for ESWL was 8 cases,three times for ESWL was 3 cases,four times for ESWL was 2 cases.The first discharge stones time was 3 to 10 days.There was no special discomfort after operation.40 cases got hematuria after operation,which occurred in 1 to 3 days after ESWL Renal colic was in 7 cases which happened on 1-3 days after ESWL.Condusions Calculi in horseshoe kidney may be treated by ESWL.It is a safe and simple operation.The prone position may bring satisfactory effect.

Objective This study aimed to define research status of age -related hearing loss ,and provide the basis and direction for future research .Methods We have retrieved all relevant literatures on age -related hearing loss from Pubmed ,and conduct an objective analysis of the existing literatures by Bibliometric analytics and co -word analysis method using co -occurrence bibliographic information mining system and SPSS22 .0 software for data analysis .Results There were a large number of articles and journals about presbycusis and age -related hearing loss .Many countries were involved in the research .Literatures and core authors were mainly from developed coun‐tries such as Europe and the United States .The quantity and quality of Chinese literatures were in a leading position in Asia .The researches focused on the common characteristics of patients ,the epidemiology ,characteristics of hear‐ing ,treatment and laboratory studies .There were some new research directions in recent 5 years ,such as factors as‐sociated with the younger ages before developing presbycusis ,standard design and use of questionnaires ,prevention and control .Conclusion Age-related hearing loss will continue to be a hot topic with growing focus on micro and macro development of multi -disciplinary cooperation .The penetration will be the trend for the future research while the prevention will become a new focus of research .

Objective:To investigate the expressions of human epidermal growth factor receptor 2 (HER2) in recurrent patients after radical gastrectomy and its correlation with clinicopathologic features and prognosis.Methods:The clinical data of 116 recurrent patients after radical gastrectomy between December 2011 and March 2019 in Fujian Cancer Hospital were retrospectively analyzed. The relationship between HER2 expression of the tissues after radical gastrectomy and clinicopathological features as well as prognosis was also analyzed.Results:HER2 positive rate was 19.8% (23/116) in gastric cancer specimens of 116 patients after radical gastrectomy. HER2 positive rate in highly and moderately differentiated patients with gastric cancer was higher than that in those with poorly differentiated gastric cancer [33.3% (11/33) vs. 14.5% (12/83), χ2 = 5.292, P < 0.05]. HER2 positive rate in patients with lung metastasis was higher than that in patients without lung metastasis [42.1% (8/19) vs. 15.5% (15/97), χ2 = 5.517, P < 0.05]. There were no statistical differences in HER2 positive rate among gastric cancer patients with different gender, age, tumor location, recurrent site, TNM stage, number of metastasis, neurovascular invasion, liver metastasis, local recurrence (all P > 0.05). HER2 expression was not associated with disease-free survival time ( P > 0.05). Conclusion:HER2 expression is associated with the differentiation degree of gastric cancer and the location of distant metastasis, but it can not be used as a predictor for recurrence of gastric cancer.
