Unilateral tubal twin pregnancy is a relatively rare ectopic pregnancy. This paper reported the diagnosis and treatment of two cases of unilateral tubal twin pregnancy admitted to Jiaozhou Central Hospital of Qingdao in 2015 and 2023, respectively, and the relevant literatures were reviewed. This paper summarized the risk factors, clinical case characteristics, clinical diagnosis and treatment methods of unilateral tubal twin pregnancy, in order to provide useful reference for early recognition, accurate diagnosis and timely treatment of unilateral tubal twin pregnancy, and reduce its incidence rate and mortality.

Objective To study the main risk factors related to the incidence of tuberculosis in China and to provide di -rections and basis for the protection of tuberculosis .Methods The results of 25 studies on the main risk factors of tubercu-losis of Chinese people from 2000 to 2012 were analyzed by meta-analysis method .Results The pooled odds radio values and 95%CI of history of exposure to pulmonary tuberculosis , smoking, marriage, contact with people, Bacille Calmette-Guerin (BCG)vaccination scar, BCG vaccination, low body mass index(BMI) , family history of tuberculosis, exposure to dust and to chemical fumes under working conditions were as follows:3.14(2.74-3.59),1.23(1.14 -1.33),3.05 (2.10-4.45),2.08(1.76-2.26),0.39(0.32 -0.47),0.58(0.46 -0.73),2.95(2.40 -3.64),2.56(1.82 -3.59),2.58(2.04-3.26),and 4.81(1.99-11.60).Conclusion Then History of exposure to pulmonary tuberculosis , smoking, marriage, contact with people , low BMI, family history of tuberculosis , exposure to dust and to chemical fumes under working conditions are considered to be the risk factors of pulmonary tuberculosis .While BCG vaccination scar and BCG vaccination are considered to be the protective factors of pulmonary tuberculosis .

Objective To investigate the characteristics of attention networks impairment in patients with lesion in the cerebellum.Methods The attention network test was used to compare patients with lesion in the cerebellum(n=28)with normal controls(n=3.1)on the efficiency of three anatomically defined attention networks:alerting,orienting,and executive control. Results The orienting network effect was significantlyworse(Z=-2.309,P＜0.05)in patients with lesion in the cerebellum((36.32±30.58) ms)than in normal controls((54.39±22.17)ms).The executive control network in patients((160.05± 83.25)ms)with lesion in the cerebellinn was worse than those of controls((93.42±37.41)ms,Z= -3.500,P＜0.01).The alerting networks effects was higher in patients((35.14±45.59)ms)than in normal controls((28.81±26.09)ms),without significant difference.The average reaction time was longer in patients than in normal controls,but there was no significant difference.The wrong rate of attention network testwas significantly higher(Z=-2.119,P＜0.05)in patients(6.57%±9.84%)than in normal controls(3.38%±5.42%).Conclusion The patients with lesion in the cerebellum may be selectively impaired of the orienting and executive networks,while the alering network is spared.
