Objective To investigate the difference in occurrence of pneumothorax and bleeding under lung biopsy between the elderly and the non-elderly. Methods A total of 297 consecutive patients were involved in the study and divided into non- elderly group (＜ 60 yrs,122 cases),and elderly group (≥60 yrs,175 cases).Eighteen gauge (18G) cutting needles were used for biopsy with computed tomography (CT) guidance. Biopsy samples were detected by histology and cytology pathology. Results Pneumothorax occured in 108 of 297 biopsies (36.4％),pneumothorax rate was higher in elderly group (76 cases,43.4％) than in non-elderly group(32 cases,26.2％) (x2=9.19,P＜0.01).No statistical significance was found in different degrees of pneumothorax between the two groups.Perifocal hemorrhage occured in 156 of 297 biopsies (52.5％),higher frequency of hemorrhage occurred in elderly group (105 cases,60.0％) than in non-elderly group(51 cases,41.8％)(x2=9.55,P＜0.01),and the more flake bleeding vas found in elderly group than in nonelderly group(x2 =20.28,P＜0.01). Conclusions In CT guided coaxial cutting needle biopsy,the incidence of pneumothorax and considerably bleeding are higher in the elderly than in non-elderly.

Objective: To investigate the trends in mortality of injury among elderly populations at ages of 60 years and greater in Huzhou City from 2010 to 2020, so as to provide the evidence for proposing preventive and control interventions of injury among the elderly. Methods : The death of injury among registered residents at ages of 60 years and older in Huzhou City from 2010 to 2020 were collected from Zhejiang Provincial Information Management System for Chronic Disease Surveillance. The mortality and main causes of injury were descriptively analyzed among the elderly, and the trends in mortality were analyzed using annual percent change ( APC ). Results: Totally 13 360 deaths occurred due to injury among elderly populations in Huzhou City from 2010 to 2020, and the mortality of injury appeared a tendency towards a rise with years ( APC=3.87%, P<0.05 ). The annual mean mortality and standardized mortality of injury were 199.89/105 and 192.68/105 among elderly populations in Huzhou City from 2010 to 2020. The overall mortality of injury was higher in men than in women during the period from 2010 to 2017, and higher mortality was seen in women than in men in 2020 ( P<0.05 ). The injury mortality in men and in women, and the overall mortality of injury all appeared a tendency towards a rise with ages ( P<0.05 ). The five most common causes of injury included fall ( 82.89/105 ), motor vehicle traffic accidents ( 26.45/105 ), suicide ( 18.52/105 ), drowning ( 16.88/105 ) and shipping accidents except motor vehicle ( 13.77/105 ), which accounted for 79.30% of all deaths due to injury. The mortality of fall in women ( APC=8.87%, P<0.05 ) and the overall mortality of fall ( APC=10.63%, P<0.05 ) both appeared a tendency towards a rise with years. Conclusion The mortality of injury appeared a tendency towards a rise and increased with ages among the elderly in Huzhou City from 2010 to 2020. Fall is the leading cause of death due to injury among the elderly.

Objective To explore the methods of embolism in simple and complex arteriovenous malformation of body.Methods Ten cases with the body arteriovenous malformations treated with interventional embolization were retrospectively analysed. Coil or detached bollon were used in simple arteriovenous malformations which could be embolized directly, while IBCA were used in complex ones, which could embolize the abnormal vascular group, blocking blood supply of multiple arteries and preventing construction of collateral circulation which could lead to recur. Results The abnormal vasculars were embolized completely in all ten cases, and there were no recurrent followed-up for 1～6 years.Conclusion Interventional embolization is a simple and credible therapeutic method for arteriovenous malformations of body , and it should be the primary plan.

Objective To study different e mbolization methods in various aneurys ms with metallic coils. Methods In 6 spherical aneurysms, the e mbolization was p erformed with coils in their bodies, discontinuing the total or part of the bloo d supply to the corresponding viscera. While in 6 diverticulum aneurysms, the em bolization with coils was conducted in their bodies only, maintaining the blood supply of the corresponding viscera. For some pseudoaneurysms, both afferent and efferent arteries were embolized and collateral arterial supplies were prevente d. Results All 19 cases 20 aneurysms, of aneurysms were success fully embolized. Among 8 cases of pseudoaneurysms, bleeding had been stopped in 7 cases. Putting coils in the b odies of aneurysms or embolizing both afferent and efferent arteries improved su ccessful rate. Conclusion Embolizing aneurysms with metallic co ils is an efficient, reliable, and simple interventional method for stopping bleeding.

Objective To study the correlation of the incidence of diverticula in the upper gastrointestinal tract and the age increasing among the people without any symptom in digestive system. Methods Six hundred and fourty-five elderly and pre-elderly people(age from 50 to 79 years)with asymptom diverticula were divided into 3 groups basing on their age:50 to 59 years group(206 cases),60 to 69 years group(201cases) and 70 to 79 years group(238 cases).Difference in numbers and locations of the diverticula in each group were analysed. Results The patients with diverticula in each group were found to be 37 cases(18.0%)、56 cases(27.9%)and 68 cases(28.6%), respectively, showing that among these 3 groups, the incidence of diverticula increased with ages (P

Objective: To investigate the mortality and years of life lost due to drowning in Huzhou City from 2012 to 2021, so as to provide insights into drowning prevention and control. Methods: The mortality surveillance data on drowning in Huzhou City from 2012 to 2021 were collected from the Zhejiang Chronic Disease Surveillance Information Management System. The crude mortality and standardized mortality of drowning by the 2010 population census data in 2010, years of potential life lost (YPLL) and working years of potential life lost (WYPLL) due to drowning were calculated. In addition, the annual percent change (APC) was used to analyze the trends in drowning mortality and the rate of YPLL and WYPLL in Huzhou City from 2012 to 2021. Results: A total of 1 681 deaths occurred due to drowning in Huzhou City from 2012 to 2021, accounting for 9.11% of total injury deaths. The overall mortality and standardized mortality of drowning were 6.35/105 and 4.70/105, respectively, and mortality and standardized mortality of drowning were 6.95/105 and 5.44/105 in men and 5.76/105 and 3.98/105 in women, respectively. The highest mortality of drowning was found in residents at ages of 65 years and older (16.04/105 to 27.02/105), followed by in residents at ages of less than 5 years (2.54/105 to 16.37/105). The overall mortality of drowning was 5.29/105 to 7.21/105 among residents in Huzhou City from 2012 to 2021, and no significant change tendency was seen (APC=-2.18%, t=-2.085, P=0.071). The standardized mortality of drowning reduced from 6.10/105 to 3.69/105 (APC=-4.88%, t=-4.215, P=0.003). In addition, the YPLL and rate of YPLL, and WYPLL and the rate of WYPLL due to drowning mortality were 22 620.50 person-years, 0.10%, 17 956.50 person-years and 0.08% in Huzhou City from 2012 to 2021, respectively, and the rates of YPLL (APC=-6.95%, t=-3.203, P=0.016) and WYPLL (APC=-7.60%, t=-3.126, P=0.014) both appeared a tendency towards a decline from 2012 to 2021. Conclusions The standardized mortality of drowning and rate of YPLL appeared a tendency towards a decline among residents living in Huzhou City from 2012 to 2021, and residents at ages of 65 years and older and less than 5 years are high-risk populations for management of drowning mortality.

Objective To study the CT features of thoracic sarcoidosis in senile and pre senile patients. Methods The findings in 25 patients(14 elderly patients and 11 pre senile patients) manifesting thoracic sarcoidosis were reviewed. Results Nine patients with typical findings and sixteen patients with atypical findings were reported at retrospective presentation. The atypical patterns at CT included mediastinal adenopathy with unilateral hilar adenopathy( n =3, 3/25), mediastinal adenopathy alone ( n =7, 7/25), unilateral hilar adenopathy alone ( n =1, 1/25), and lung abnormal findings without any mediastinal and/or hilar adenopathy ( n =5, 5/25). The latter 5 patients were misdiagnosed at the first clinical consultation. Conclusions The thoracic sarcoidosis in the elderly often manifests atypical patterns, and the recognition of the key point is of importance and helpful for the definite diagnosis.

Objective To study the CT appearances in the atypical thoracic sarcoidosis Methods Chest CT findings of 43 patients with proven sarcoidosis were reviewed retrospectively Results 22 cases (51 16%) had atypical thoracic sarcoidosis findings at presentation The atypical patterns on CT included mediastinal adenopathy alone ( n =9) or in combination with unilateral hilar adenopathy ( n =6), and unilateral hilar adenopathy alone ( n =1) 6 patients had abnormal findings in the lung alone without adenopathy, and they all had been misdiagnosed 18 atypical cases (81 82%) occurred in patients older than 50 years, whereas 4 atypical cases (18 18%) occurred in patients younger than 50 years Conclusion Half patients with thoracic sarcoidosis have atypical CT appearances, it frequently occurs in elderly patients, and the diagnosis is easily mistaken on CT scan

To explore the therapeutic effect of micro-traumatic surgery of loose seton and cutting seton by rubber bands in the treatment of high anorectal fistulae.Application of cutting seton (truss rubber bands) implemented the high part of fistulae and loose seton (ligation rubber band but non-fastened) for the low part of fistulae.133/136 patients undergoing micro-traumatic surgery were cured by one operation,2 cases had pseudo-healing and there was 1 recurrent case.And the curative rate was 97.8％.The microtraumatic surgery of loose seton and cutting seton by rubber bands in the treatment of high anorectal fistula has such multiple advantages as small incision,minor trauma,lesser pain,faster healing and a shorter course of treatment.And it may preserve the proper anal function and the integrity of anal skin.And its clinical efficacy is satisfactory.
