BACKGROUND:The rabbits were widely used as experimental animal models in the research on etiology and pathological mechanism of steroid-induced osteonecrosis of the femoral head. It is stil a valuable and realistic research topic to improve and to innovate the modeling technology nowadays. OBJECTIVE:To improve the modeling technology on osteonecrosis of the femoral head in rabbits induced by glucocorticoid combined with lipopolysaccharide, with the focus on its reduced mortality and the guaranteed successful rate of modeling. METHODS:A total of 28 New Zealand white rabbits were randomly divided into the control group (n=10) and improvement group (n=18). Models of steroid-induced osteonecrosis of the femoral head were established according to different methods. In the improvement group, rabbits were injected with sodium penicilin (5.0 mg/kg) and amikacin sulfate (1.63×104 U/kg) in the left gluteus muscle. Twenty-four hours later, al rabbits were injected with prednisolone acetate (20 mg/kg) in the right gluteus muscle. Forty-eighthours later, 5.0 μg/kg of lipopolysaccharide was intravenously injectedvia the ear. From then on, two injections of prednisolone acetate (20 mg/kg) were respectively performed alternately in the left and right gluteal muscle at an interval of each 24 hours. Sodium penicilin (5.0 mg/kg) and amikacin sulfate (1.63×104 U/kg) were intraperitonealy injected for 2 consecutiveweeks. In the control group, 10 μg/kg lipopolysaccharide was injectedvia the ear vein of rabbit. From then on, prednisolone acetate (20 mg/kg) was intramuscularly injected at an interval of each 24 hours, totaly three times. Benzylpenicilin sodium 20×104 U/rabbit was intramuscularly injected once a week. RESULTS AND CONCLUSION:Rabbit models of steroid-induced osteonecrosis of the femoral head were successfuly established in both groups. Compared with the control group, the mortality was significantly reduced after model establishment in the improvement group, and the bone lacuna and osteonecrosis of the femoral head were apparent. These findings indicated that the improved technology of model establishment of steroid-induced osteonecrosis of the femoral head could be used to aleviate the damage degree on the gluteal muscles, to guarantee the successful rate of modeling, and to noticeably reduce the mortality of rabbits.

Objective To explore the long-term effect of bronchial artery, embolization (BAE) in patients with massive hemoptysis and the factors associated with prognosis. Methods Ninety six patients underwent BAE from 2002 to 2008 for the management of mass hemoptysis were retrospectively analyzed. Of them, BAE was successfully performed in 94 patients (mean age 43 years, age range 21 to 80 years), including active or inactive tuberculosis (89 cases), bronchiectasis (2 cases) and pulmonary carcinoma (5 cases). Results BAE resulted in an immediate cessation of hemoptysis in 94 of the initial 96 patients (97.9%). The rate of hemoptysis controlling at 30 d, 90 d, 1 year and 2 year after the BAE was 93.6% (88/94), 86. 2% (81/94), 81.9% (77/94) and 78.7% (74/94) respectively. Haemoptysis recurred in 9 patients in 30 days after the BAE due to missing of target vessel or recanalization. Five patients had recurrence of haemoptysis after 30 days and 2 patients recurrent after 90 days due to development of systemic collateral, progress in primary lesions and secondary infection. Conclusion BAE is an effective technique in the emergency treatment of massive hemoptysis. Avoiding missing target vessel, selecting the appropriate embolic material, paying attention to treatment of the primary disease after BAE, and preventing infection would improve the effects of BAE for massive hemoptysis.

Objective: To evaluate the application of panning axial turnover in placement of surgical positions before thoracic surgery. Methods: From June 2017 to September 2017, altogether 140 patients who underwent thoracic surgery were enrolled in and randomly divided into two groups: the observation group and the control group. The control group was treated with traditional turnover method, while the observation group were treated with axial turnover. Results: No significant changes were found in blood pressure, heart rate and respiratory rate (P>0.05) after turning over. There was no significant difference between the observation group and the control group about turn over time, (7.06±0.78)s vs. (7.01±0.81)s (P>0.05). The subjective evaluation results of the medical staff in the observation group were significantly better than those of the control group (Z=-7.111, P<0.01) and the shift rate of double-lumen endotracheal tube in the observation group was 3.7% (2/54), which was significantly lower than 21.6% (11/51) of the control group (χ²=6.158, P<0.05). Conclusions The panning axial turnover properly guided the turn-over work with the principle of human body mechanics, which was more labor-saving and requires less operators. Besides, the panning axial turnover effectively reduced the double-lumen tracheal intubation shift rate. It′s worthy of clinical promotion.

[Summary] Four patients with hyperthyroid-associated exophthalmos, myxedema, acropachy ( EMA ) syndrome, including three male patients and one female patient were diagnosed with Graves′diseases and treated by 131 I therapy. Complaints of thyrotoxicosis were presented at the onset. Tibia myxedema and acropathy appeared, and eye symptoms aggravated in two patients after anti-thyroid drug therapy and 131 I therapy. Four cases were all given clobetasol propionate, miconazole nitrate, neomycin sulfate and urea cream alone or in combination with compound betamethasone local injection treatment, and three cases were given low-dose oral prednisone treatment. Complaints of tibia myxedema and eye symptoms were significantly improved after the treatment. Therefore, we should be wary of the occurrence of hyperthyroid-associated EMA syndrome after 131 I therapy. Corticosteroid might be the effective therapy for myxedema and eye symptoms of EMA syndrome.

Objective To investigate the prevalence of and predisposing factors of atopic dermatitis (AD ) in 0 - 6 year-old children in rural and urban area of Tianjin. Methods The subjects were chosen by cluster sampling from kindergartens in Tianjin's urban and rural districts. Questionnaires were designed based on the International Study of Asthma and Allergies in Children (ISAAC ) and distributed to the children's parents via the teachers. Results In this survey, 3 749 questionaires were returned, of which 3 708 were valid. The response rate was 82.7% in total, 79.3% in the rural area, and 84.9% in the urban area. The age and gender distributions were similar in the urban and rural area. The prevalence rate of AD in these children was 2.9% in total, and it was higher in the urban area than in the rural area (3.5% vs 2.4%, x2 = 3.98, P

OBJECTIVETo summarize the clinical characteristics of alternating hemiplegia of childhood (AHC).

METHODSThe clinical data of 13 children with AHC were analyzed. Cranial MRI, EEG, analysis of serum amino acids and urinary organic acids, measurement of plasma lactate and pyruvate levels were done in all patients. Other laboratory examinations such as magnetic resonance angio-imaging (MRA), digital subtraction arteriography (DSA) and Video-EEG were also performed in some patients.

RESULTSOf the 13 patients, 12 were male, and 1 was female. The age of onset was from 2 days to 55 months (average 13.1 months). The initial symptoms were abnormal ocular movements (AOMs) consisting of ocular deviation, gaze or nystagmus in 2 cases, AOMs and dystonic posturing in 9 cases, hemiplegia in 2 cases. All patients had recurrent alternating hemiplegic episodes. The hemiplegic attacks lasted from a few minutes to 10 days. The occurrence of the attacks ranged from 8 times daily to one time every 2 months. In 10 patients the abnormal eye movements or dystonic posturing, at times, recurred intermittently during the hemiplegic attack. Choreoathetosis was present in 2 cases. Ataxia was present in 1 case; 7 patients also had the episodes of quadriplegia. During the episodes of quadriplegia, dysarthria or aphasia was present in 4 cases, dyspnea and dysphagia was present in 2 cases, respectively. Sleep could relieve both weakness and associated paroxysmal symptoms. Mental retardation was present in 9 cases, seizures in 3 cases. Except for EEG or Video-EEG was abnormal in 3 patients, other laboratory investigations were normal in all patients. Twelve patients received flunarizine therapy. Flunarizine reduced the severity, duration, or frequency of hemiplegic attacks in 8 patients.

CONCLUSIONThe results suggest that AHC is characterized by frequent episodes of alternating hemiplegia with extrapyramidal symptoms and mental retardation, flunarizine is effective in treating some AHC patients.
