This paper presents 332 cases of traumatic intracranial hematoma treated at Shenyang command general hospital during the period from October 1980 to October 1987. Among them, 111 cases had brain hernia at the time of admission. The overall mortality was 16.9%, of which 'supra-acute type' (brain hernia occurred within 3 hours after trauma) was 57.1%, acute type 9.3%, and subacute type was zero. The mortality of epidural, subdural, intracerebral, multiple and intraventricular hematoma, were 3.8%, 39.1%. 7.5%, 27.9% and 50%, respectively. The authors believe that CT scan playsa decisive role in the diagnosis of intraventricular, intracerebellar, and basal ganglionic hemaloma, since without CT it can not be diagnosed. In addition, the authors hold that successive observation of patients with CT scans is also of utmost importance, particularly for those with delayed and multiple he-matomas. Furthermore, take every measures to prevent complications and adequate management of brain iniury itself were other two factors in decreasing the mortality of traumatic intracranial hematoma.

Objective To investigate traditional Chinese medicine (TCM) syndrome differentiations and glycosylated hemoglobin (HbA1c) levels in the young and middle-aged type 2 diabetic patients with heart failure and preserved ejection fraction (HF-PEF), and to evaluate the correlations between them.Methods 235 out- and hospitalized patients with type 2 diabetes from Department of Cardiology of Affiliated Fuzhou Second Hospital of Xiamen University were enrolled. They were divided into HF-PEF group (120 cases) and non-HF-PEF (HF-NPEF) group (115 cases) according to the diastolic function results of echocardiography. In the HF-PEF group, according to the TCM differentiation of syndromes, the patients were subdivided into four types: heart Qi and Yin deficiency, Yang deficiency of heart and kidney, Qi deficiency and blood stasis and edema syndrome due to Yang deficiency syndromes. The HbA1c levels of different TCM syndromes in HF-PEF and HF-NPEF groups were determined by high performance liquid chromatography. The patients of HF-PEF were further divided into two groups according to serum HbA1c levels > 7.0% or ≤ 7.0%, and the relationships between different serum HbA1c levels and different severity of TCM syndrome types of patients with HF-PEF were compared.Results The level of serum HbA1c in HF-PEF group was significantly higher than that in HF-NPEF group in patients with type 2 diabetes [(7.02±0.74)% vs. (6.79±0.91)%,P < 0.05]. There was no significant difference in HbA1c levels between heart Qi and Yin deficiency type and Yang deficiency of heart and kidney type in HF-PEF group [(6.70±0.66)% vs. (6.70±0.68)%,P > 0.05], while the HbA1c levels of Qi deficiency and blood stasis and edema syndrome due to Yang deficiency syndromes were significantly higher than those of heart Qi and Yin deficiency and Yang deficiency of heart and kidney types [(7.15±0.70)%, (7.55±0.62)% vs. (6.70±0.66)%, (6.70±0.68)%], and the HbA1c levels of edema syndrome due to Yang Deficiency was obviously higher than that of Qi deficiency and blood stasis (P < 0.01). In group of HbA1c > 7.0%, the incidence rate of Qi deficiency and blood stasis and edema syndrome due to Yang Deficiency types was higher than that of the group of HbA1c ≤ 7.0% [61.97% (44/71) vs. 38.78% (19/49),P < 0.05]. Pearson correlation analyses indicated that the number of patients with HF-PEF was positively correlated with HbA1c level in HF-PEF group (r = 0.610,P < 0.05); the HbA1c level was positively correlated with the number of patients with Qi deficiency and blood stasis and edema syndrome due to Yang Deficiency in HF-PEF group with HbA1c > 7.0% (r = 0.683,P < 0.05).Conclusion Clinically using serum HbA1c level to assess the prognosis of HF-PEF has obtained consistent results, and the level is positively correlated to the development of TCM syndrome types in young and middle-aged HF-PEF patients with type 2 diabetes.

A method of solid phase extraction coupled with ultra performance liquid chromatography-tandem mass spectrometry ( SPE-UPLC/MS/MS) was developed for the determination of 15 phthalate esters. Drinking water samples were concentrated by C18 SPE cartridge. The fifteen phthalate esters were separated on a phenyl column with gradient elution using methanol and water as mobile phases. Multiple reaction monitoring ( MRM) acquisition under positive ion mode was performed. The external matrix standard solutions were used for the quantitative determination. The linear range of Di-n-butyl phthalate was 0. 63-1000 μg/L. The other 14 phthalate esters showed good linearity in the range of 0 . 002-500 μg/L with the correlation coefficients more than 0. 9970. The limits of quantification ( LOQ) were 2. 2-632 ng/L. The spiked recoveries ranged from 81 . 3% to 109%. The relative standard deviations were less than 14%.
