Objective To compare the efficacy of sequential therapy combined with probiotics,pure sequen-tial therapy and standard triple therapy for Helicobacter pylori eradication.Methods Selected the clinical data of 240 patients admitted.The 240 patients were randomly divided into 3 groups.Group A received standard triple thera-py,group B received sequential therapy and Group C received sequential therapy in combination with probiotics. Then,we compared the eradication rate,the score of gastrointestinal tract symptoms before and after treatment,and the side effects among 3 groups.Results The eradication rate was 72.5% in groupA,87.5% in group B,and 96.3% in group C.The eradication rate of group C was significantly better than group A and group B (χ2 =18.531,P <0.001).There was no difference in the score of gastrointestinal tract symptoms before treatment(F =0.206,P >0.05),but they all significantly decreased after treatment among 3 groups(P <0.05),with group C a better result(F =25.581,P <0.05).The side effects of 3 groups were 16.3%,13.8%,3.8%,respectively.There were a significantly differencec between group C and the other 2 groups(χ2 =7.011,P =0.030).Conclusion Sequential therapy in combination with probiotics can achieve a higher eradication rate,improve the score of gastrointestinal tract symptoms, and decrease side effects.

ObjectiveTo evaluate the changes of left atrialsize and function after transeatheter closurein adults with atrial septal defect(ASD).Methods Forty-nine adults with ASD received transcatheter closure successfully were chosen.Transthoracic echocardiogram examination was performed to detect the diameter and volume of left atrium before treatment and in 2 days,1,3 and 6 months after treatment.ResultsLeft atrial diameter in 2 days,1 and 3 months after treatment compared with that before treatment had no statistical significance (P ＞ 0.05),and the data in 6 months after treatment was shorter than that before treatment [ (32.06±4.78 ) mm vs.(34.63±5.60) mm,P ＜ 0.05 ].Left atrial total volume reduced in 2 days after treatment compared with that before treatment [ (30.84±4.24) ml vs.(32.43±4.30) ml,P ＜0.05],and further reduced in 3 and 6 months after treatment [(30.51±4.97),(28.94±5.97) ml vs.(32.43±4.30) ml,P ＜ 0.05 or ＜0.01 ].Left atrial active emptying volume before and after treatment had no statistical significance(P ＞ 0.05 ).Left atrial passive emptying volume in 2 days and 1 month after treatment showed no statistical significance compared with that before treatment (P ＞ 0.05),and reduced significantly in 3 and 6 months [ (10.28± 5.51 ),(10.27± 4.82) ml vs.(12.31± 3.51 ) ml,P ＜ 0.01 ].Compared with that before treatment,left atrial ejection fraction in 2 days after treatment had no significant difference(P＞0.05 ),and had statistical significance in 1,3 and 6 months after treatment [(41.70± 7.00)％,(45.47±5.23 )％,(48.55± 7.86)％ vs.(37.39± 4.84 )％,P ＜ 0.01 ].ConclusionThe formation and function of left atrium of adults with ASD would be significantly improved after transcatheter closure.

Objective:To assess the possibility of suicide in setting condition among urban and rural residents samples in northern China.Methods:By randomly sampling,1007 persons aged 18 years or older were selected from 10 urban neighborhoods in Beijing and from 10 rural village in Hebei province.The Survey Schedule of Atti-tudes in China in which 24 negative life events were listed,and the possibility of committing suicide was asked to the subjects when they encountered the supposed events.Results:The rates of thinking about committing suicide when encountered the supposed life events were 65.2% of incurable illness,62.0% of burden on other and no future hope,61.2% of drug dependence,57.3% of large debt due to gambling,54.2% of being raped, 51.6% of severe depression,50.7% of being elderly and no family to provide support.Only 14.6% of the ur-ban and rural residents would not consider suicide when encountered any type of supposed problems.Conclusion:There is higher possibility of considering suicide in urban and rural residents when encountered negative life events, so it is important to give support to the residents with one or more life events.

Objective To study influences of intervention in pregnant women with positive thyroid autoantibodies on the thyroid function of babies. Methods A total of 55 pregnant women were enrolled with positive thyroid peroxidase antibody (TPOAb) and/or thyroglobulin antibody (TgAb) during prenatal checkup. They were randomly divided into two groups: intervening group( n= 36, newborn group A) was treated with levothyroxine ( L-T4 ), and non-intervening group ( n= 19, newborn group B) was not treated. 30 cases of pregnant women with negative thyroid autoantibodies served as a normal population control group (newborn group N). Serum TSH, TPOAb, TgAb, TT3, TT4, FT3 and FT4 were measured by high-sensitive immunochemiluminescent assay ,and urinary iodine was also examined in the pregnant women. Fetal plasma TSH, TT3, TT4, FT3, and FT4 levels were measured after cutting the umbilical cord from placenta, and repeated measurements were made by 3-4 weeks and 8-10 weeks postpartum. Results At baseline, serum TSH levels of the pregnant women in intervening and nonintervening groups were significantly higher than that in control group ( P＜0.05 ). Non-intervening group had higher TSH and lower TT3, TT4, FT4 compared with the other two groups (P＜0. 05 or P＜0.01 ). The cord blood TSH levels of the neonates in both group B [(7.06 ± 1.31 ) mIU/L] and group A [(6.23 ± 1.26 ) mIU/L] were significantly higher than that of group N [(5.48±1. 17) mIU/L, P＜0.01 and 0. 05]. By 3-4 weeks postpartum,the serum TSH level [(3.21±0.70)mIU/L] in group B was significantly higher than those in group N [(2.72±0.51)mIU/L] and group A [(2.78±0.42) mIU/L, all P＜0.05]. The serum TSH level in group B [(2.99±0.57) mIU/L] was still higher than those in group N [(2.48±0.68) mIU/L] by 8 to 10 weeks postpartum (P＜0.05 ). Multiple stepwise regression analysis revealed that TSH, TPOAb, and urine iodine levels of mothers were independently related to TSH of their infants. Conclusion When differences in thyroid function exist in pregnant women, these differences also reside in their offspring. The thyroid function in neonates correlates with both the thyroid autoantibodies and thyroid function of their mothers.

Platypnea orthodeoxia syndrome is associated with dyspnea and arterial oxygen desaturation accentuated by an upright posture. It can be secondary to an intracardiac shunt. We report a case of platypnea-orthodeoxia syndrome (POS) in a 58-year old male patient who had a pre-existing patent foramen ovale (PFO) and substantial pulmonary pathologies. He was successfully treated by percutaneous transcatheter closure of the PFO. Our case highlights the importance of recognition of this rare syndrome in patients who present with unexplained hy-poxia for whom transcatheter closure of the interatrial shunt can be safely carried out.

Objective: To compare the efficacy and safety of Cardi-O-fix patent foramen ovale (PFO) occluder and Amplatzer PFO occluder for the treatment of patients with PFO. Methods: A total of 246 consecutive patients (105 males and 141 females) with PFO were prospectively enrolled from May 30, 2013 to March 30, 2015 in our hospital. PFO interventional closure was applied according to the anatomical structure of the disease and patients′ wishes.Cardi-O-fix PFO occluder was used in 180 cases (COF group), Amplatzer PFO occluder was used in the remaining 66 cases (Amp group). Post-procedure safety including recurrent stroke, transient ischemic attack, death, and complete closure rate, and efficacy including procedure related complications of different devices were compared during the 12 months follow-up. Results: (1) Rate of transient ischemic attack was similar between COF group and Amp group at 12 months after procedure(1.1%(2/180) vs. 1.5%(1/66), P=1.000). There was no recurrent stroke and death during the 12 months follow-up period.Complete closure rate was similar between COF group and Amp group at 12 months after the procedure(90.6%(163/180)vs. 86.4%(57/66), P=0.355). (2) Three cases(1.7%) of paroxysmal atrial fibrillation were observed in COF group during the 12 months follow-up period, 1 patient converted spontaneously to sinus rhythm and 2 patients received successful pharmacologic conversion and converted to sinus rhythm. One patient(1.5%)developed paroxysmal atrial fibrillation and was pharmacologically converted to sinus rhythm in the Amp group. There was no significant difference in rate of paroxysmal atrial fibrillation between the two groups(P=1.000). There was no complications such as occluder translocation, erosion, pericardial effusion and puncture site bleeding in the 2 groups during the 12 months follow-up. Conclusion Efficacy and safety are similar for PFO treatment with Cardi-O-fix PFO occluder or Amplatzer PFO occluder in this patient cohort.

OBJECTIVETo observe the effect of oversized occluder on endothelialization post percutaneous closure of experimental atrial septal defect (ASD) in dogs.

METHODSASD was established with the help of transthoracic echocardiography in 18 dogs. ASD size was (6.0 ± 0.2) mm. Dogs were randomly divided into normal size group (implanted with 8 mm occlude, n = 9) and oversized group (implanted with 12 mm occluder, n = 9). Dogs were randomly killed at 3, 6 and 14 months after percutaneous closure. The endothelialization process on device surface was observed by scanning electron microscope.

RESULTSFour animals died around 1 month post procedure. Microscopic sections from normal group showed nearly complete endothelialization at 3 months after device implantation and complete endothelialization at 6 and 14 months after device implantation. While microscopic sections showed lack of endothelialization at 3 months post implantation, nearly endothelialization at 6 months, and complete endothelialization at 14 months after device implantation in oversized group.

CONCLUSIONIncomplete endothelialization of occluder surface is observed at 6 months after implantation of an oversized ASD occluder device in this model.

Objective:To explore the effect of sports training guidance based on Internet platform on the limb function and quality of life in home rehabilitation of stroke hemiplegic patients.Methods:Eighty patients with stroke and hemiplegia admitted to Beijing Rehabilitation Hospital Affiliated to Capital Medical University from June 2018 to December 2019 were selected and divided into observation group and control group with 40 cases in each group by random digits table method. The control group was given routine rehabilitation training. In addition to the regular rehabilitation training, the observation group was supplemented with home rehabilitation based on the WeChat platform for modified constraint-induced movement therapy. The limb motor function Fugl-Meyer Assessment (FMA) score, Upper Extremity Function Test (UEFT) score, Stroke-Specific Quality of Life scale (SS-QOL) score before and after intervention, and patients′ satisfaction and cares′ satisfaction score were compared between the two groups.Results:There was no significant difference in the score of FMA, UEFT, SS-QOL before intervention between the two groups( P>0.05). After discharge, the FMA score, UEFT score and physical function, physiological function, mental health, social function of SS-QOL score were (68.87±6.64),(72.38±7.33), (35.28±4.13), (36.55±4.23), (37.22±3.84), (38.23±3.44) points in the observation group and (55.25±6.20), (61.24±6.47), (28.72±4.56), (30.85±5.30), (31.28±4.63), (31.02±5.16) points in the control group, and the differences were statistically significant between the two groups( t values were 5.316-9.482, P<0.01). During the nursing period, the patients′ satisfaction and cares′ satisfaction score were 92.50%(37/40), 87.50%(35/40) in the observation group and 72.50%(29/40), 67.50%(27/40) in the control group, and the differences were statistically significant between the two groups( χ 2 values were 5.541, 4.588, P<0.05). Conclusions:The home rehabilitation based on the Internet platform for modified constraint-induced movement therapy helps to promote the recovery of limb motor function in stroke hemiplegic patients, improve the nursing satisfaction of patients and their families, and has a positive effect on improving the quality of life of patients.
