Objective To evaluate the tests in differential diagnosis of subtypes in patients with primary aldosteronism. Methods Fifty-seven patients in the past 7 years chnically diagnosed as primary aldosteronism [22cases of aldosterone-producing adenoma (APA), 26 idiopathic hyperaldosteronism (IHA) and 9 primary adrenal hyperplasia (PAH)] were selected. The plasma potassium, basic and upright plasma renin activity, plasma and urinary aldosterone were determined. 19 patients with essential hypertension served as control. All patients with primary aldosteronism underwent adrenal CT, postural stimuhtion test (PST) and adrenal venous sampling (AVS) to differentiate the subtypes. The clinical and laboratory data were followed up during survey. Results (1) The patients with APA had higher blood pressure and aldosterone level in plasma or urine, but lower plasma potassium and plasma renin activity than those with IHA. In PAH group, these parameters were in the ranges between APA group and IHA group. For the diagnosis of APA, IHA and PAH, the coincidences were 86.4%, 73.1% and 22.2% by adrenal CT, 86.4%, 80.8% and 77.8% by the ratio of aldosterone in both sides of AVS and 95.5%,92.3% and 100.0% by the ratio of aldosterone to cortisol in beth sides, respectively. (2) The plasmaaldosterone, systohc and diastolic blood pressure were decreased after operation in the patients of APA and PAH,and no significant changes were found in patients with IHA. Conclusion The abnormal laboratory findings in patients with APA axe more evident than those in IHA. The result of PST is overlapping considerably in cases ofAPA and IHA. Adrenal venous samphng yields a high coincidence, which should be done in patients with negative CT scanning. The ratio of aldosterone to eortisol in AVS is more reliable. The clinical and laboratory data,especially plasma potassium will be improved after operation in patients with APA and PAH. But there is no change in patients with IHA during the follow-up period.

Objective To explore the clinical characteristics of eosinophilic gastroenteritis. Methods The clinical data of 2 children with eosinophilic gastroenteritis was retrospectively analyzed. Results Eosinophilia was found in both cases and path-ological examination indicated eosinophil infiltration in intestinal mucosa. The clinical symptoms were improved after hypoaller-genic diet, amino acid formula and anti-allergy treatment. Conclusions Eosinophilic gastroenteritis is characterized by eosino-phil infiltration with unknown pathogenic factor leading the treatment of eosinophilic gastroenteritis lacking of sound evidence.

Intertrochanteric fracture is the most common hip fracture. Due to severe osteoporosis and high degree of fracture comminution, initial implant failure or nonunion occasionally occurs. It is still controversial how to formulate a more effective strategy for revision and fixation after failed primary operation for patients who have high functional needs and/or long-life expectancy. Common surgical procedures include angle-stabilized extramedullary plate systems (dynamic condylar screw or dynamic hip screw), cephalomedullary nail systems (proximal femoral nail antirotation, InterTAN, and trochanteric fixation nail advanced) with/without medial augmentation plate. For patients with intertrochanteric fracture who have suffered from primary operation failure, the basic principle for revision is to mechanically reconstruct the stable triangular structure of the proximal femur in order to improve the mechanical stability of the fracture ends as much as possible so that fracture healing and early functional exercise can be ensured. This paper reviews the clinical and biomechanical studies published, analyzes the mechanical factors responsible for failure of initial surgery, summarizes revision strategy and clinical prognosis, and provides our clinical experience and technical innovations, hoping to help clinicians in choosing an optimal revision strategy.

Objective To exam the personality traits and self-concept of school phobia patients with different academic achievements.Methods 38 school phobia patients with high academic achievement and 19 school phobia patients with low academic achievement were assessed with Eysenck' s personality questionnaire and Piers-Harris Children' s Self-concept Scale.Results High academic achievement group of psychoticism and neuroticism higher than that of low academic achievement group.High academic achievement group of Self-concept's total scores,behavior,intelligence and the school situation higher than that of low academic achievement group.High academic achievement group of anxiety scale score lower than that of low academic achievement group.The personality traits of school phobia correlated with the self-concept on some level.Conclusion Different academic achievements of school phobia patients have different personality traits and have different self-concept,so they need to individualized treatment options.

Conclusion The major allergens of Metapenaeus ensis purified by ion-exchange chromatography and gel filtration have effective immunoreactivity and can be used as specific antigen in ELISA reagent.

Objective To understand the current status of Toxoplasma gondii(TOX)infection among pregnant women and to explore the risk factors in some areas of Lhasa City,Tibet. Methods From 2015 to 2016,3 districts(counties)of Lhasa City were chosen as the investigation sites,and 200 pregnant women in each district(county)were selected as the investigation objectives. Meanwhile,450 pregnant women from Xuzhou,Yangzhou,Wuxi cities in Jiangsu Province were chosen as the con?trol. Then the blood samples of the pregnant women both in Lhasa and Jiangsu were detected by ELISA for TOX antibodies IgG , IgM,and the detection results were analyzed and compared. In addition,the individual information of the pregnant women in Lhasa City was surveyed by questionnaires,and the related risk factors of TOX infection were analyzed. Results Among 600 pregnant women investigated in Lhasa City,there were 99 pregnant women with positive TOX antibodies,and the positive rate was 16.50%,which was significantly higher than that(5.11%)of the pregnant women in Jiangsu Province(P<0.05). There was no statistically significant difference among the 3 districts(counties)of Lhasa City in the positive rates of pregnant women (P>0.05). The positive rates of the women who preferred raw meat or had the intimate contact with animal were high. Conclu?sions Compared with Jiangsu Province,the infection rate of TOX among pregnant women in Lhasa City is high. Therefore,the comprehensive measures including health education,early examination and treatment should be taken actively,so as to prevent and control TOX infection in this area.
