Objective To establish an accurate method for determining the content of three components in Fufang Buwu Syrup. Methods TLC scanner was selected to detect three components with silica gel G thin layer plate. The sample was separated by using cyclohexane-ethyl acetate-methylenechloride-formic acid (3∶1∶1∶0.2),λS=300 nm. Results The linearity between peak area and ferulic acid was achieved in the range of 0.36-0.84μg, psoralen was achieved in the range of 0.12-0.28 μg, emodin was achieved in the range of 0.01-0.05 μg. The average recovery was 100.7%, 100.8%, 101.0%, and RSD was 1.26%, 1.44%, 1.86%, respectively. Conclusion The method is simple and accurate, which can be used for quality control of Fufang Buwu Syrup.

The aim of this study is to improve liposome encapsulation efficiency of water soluble drug ATP-2Na with hydrophobic ion pairing method, and evaluate its effect on tissues energy state in myocardial ischemia mice. Ion pair complex of ATP-2Na with HTAB was prepared first; then the liposomes were prepared by ethanol injection method. The size and zeta potential of ATP-2Na liposome were investigated. Its effect on tissues energy state in myocardium ischemia mice was evaluated by detecting ATP-2Na concentration in tissues and blood after injection in comparison to ATP-2Na solution. The diameters and zeta potential of ATP-2Na liposomes were (144.0 +/- 2.7) nm and (+16.2 +/- 1.6) mV, respectively. The encapsulation efficiency was (85.02 +/- 2.31) %. The in vitro drug release pattern from liposomes matches with Weibull equation. Compared with ATP-2Na solution, ATP-2Na liposome increased the ATP concentration of blood in myocardial ischemic mice very significantly; compared with blank, ATP-2Na liposome increased ATP content of myocardium and liver in myocaridal ischemic mice significantly, but ATP-2Na solution didn't show this effect. ATP-2Na liposome might have an advantage in improving tissue energy state on myocaridal ischemic animals.

Objective To explore the prediction value of Nottingham hip fracture score(NHFS) on postoperative complications in patients undergoing hip surgery. Methods From January 1st 2015 to January 26th 2018, data of 904 patients who had underwent hip surgery were retrospectively analyzed. According to the NHFS, patients were divided into two groups: NHFS ≤4 scores group (783 cases) and NHFS>4 scores group (121 cases). Patients′sex, age, height, weight, ASA grade, preoperative diagnosis, the modes of operation and anesthesia, hospital length of stay, blood loss and urinary volume, blood transfusion, using vasoactive agents, living in an institution, preoperative nurse, post-operative complications were compared. The relationship between preoperative NHFS and postoperative complications were analyzed. Results There were no significant differences between the two groups in height, weight and blood loss (P>0.05), and 24 patients were transferred to the intensive care unit for further treatment after the operations, and 5 patients were dead during hospital stays. Compared with those in the patient of NHFS≤4 scores group, the post-operative length of stay and total hospital length of stay were significantly prolonged (P<0.05) in the patients of NHFS>4 scores group. Between the two groups, there were significant differences in the proportion of the male gender, body mass index, age, living in an institution, ASA grade Ⅲ- Ⅳ, proportion of fracture, the mode of anesthesia, urinary volume, proportion of blood transfusion and using vasoactive agents (P<0.05). Postoperative renal insufficiency, pulmonary infection, heart failure or myocardial infarction, arrhythmia, deep vein thrombosis (DVT), acute cerebral infarct, electrolyte disturbance, hypoxemia, delirium, further intensive care unit treatment had significant differences between the two groups (P<0.05). Conclusions Postoperative complications are more likely to occur in patients with higher NHFS, which might delay the postoperative length of stay and total hospital length of stay, and lead to further treatment in the intensive care unit or even mortality after the operation.

Objective To investigate the expression and effect of secondary lymphoid tissue chemokine(SLC)in experimental ulcerative colitis(UC)in rats.Methods Thirty Spague-Dawley rats were divided into control group and UC group.SLC expression in colon tissues was detected by RT-PCR and immunohistochemistry,respectively.Results The transcriptional level of SLC in UC tissues was significantly higher than that in the control group(0.846?0.07 vs 0.312?0.12,P<0.01).The positive expression of SLC was concentrated mainly on submucosa,and the positive rate of SLC protein expression in UC group significantly higher than that in control group(P<0.01).Conclusion SLC overexpression could contribute to the pathological processes in UC rats,thus SLC may be an ideal ther- apeutic target for UC.

OBJECTIVEX-linked adrenoleukodystrophy (ALD) is a genetically determined disorder that involves the nervous system white matter, axons, adrenal cortex and testes. The typical clinical manifestations are progressive psychomotor regression, vision and/or auditory impairment and adrenal insufficiency. The clinical manifestation, biochemical change and genetic counseling work of X-linked ALD were analyzed.
METHODSThe clinical features of 29 cases with ALD were summarized and analyzed, including symptoms and signs, measurement of blood very long chain fatty acids (VLCFA), adrenal function, cranial magnetic resonance imaging (MRI) and pedigree investigation.
RESULTSAmong these 29 cases, the clinical phenotype could be classified into childhood cerebral (22 cases), adolescent cerebral (4 cases), adrenomyeloneuropathic (1 case), Addison's disease (1 case) and asymptomatic or presymptomatic (1 case) types. Nine of them had positive family history. Pedigree investigation was consistent with typical sex-linked recessive inheritance. There were 45 ALD patients in these 29 pedigrees. The neurological manifestations varied among members of the same family. Nine cases died during follow up. The causes of death were central respiratory failure or other complications of ALD and so on. Laboratory tests demonstrated abnormally high plasma levels of VLCFA in ALD patients; MRI demonstrated symmetric butterfly-like low T(1) and high T(2) signals in the parieto-occipital white matter. The impairment in the splenium of corpus callosum made the bilateral lesion region converge into one. It could progress anteriorly and injure the bilateral posterior limb of internal capsule and the temporal lobe, and could injure the brainstem inferiorly. Following intravenous injection of contrast material, thin stripe of lacelike enhancement could be observed.
CONCLUSIONSThe atypical initial symptom of ALD was seizures. The MRI showed abnormal signal in the cerebellar white matter. This disease can influence the normal development of children, this was more pronounced in the childhood cerebral ALD type. It tended to progress rapidly with dementia, vegetative state or death. Since antenatal diagnostic method is available now, emphasis should be made on the antenatal examination in order to make an early diagnosis and abort pregnancy if necessary.

OBJECTIVETo explore the incidence of dementia among elderly people in Xi'an and its related risk factors.
METHODSSubjects that had been studied on the prevalence of dementia were follow-up, and the incidence of dementia, Alzheimer disease (AD) , and vascular dementia (VD) were counted by person-years. The clinical diagnosis on dementia,AD and VD were based upon the 3rd Edition of Diagnostic and Statistical of Manual of Mental Disorder, Revised version (DSM-III-R) and NINCDS-ADRDA criteria.
RESULTS2197 subjects of non-dementia being identified in 1998, were re-surveyed in 2001. Out of them, 47 new cases of dementia including 37 cases of AD and 8 cases of VD were identified, with an annual incidence rates of dementia, AD and VD as 0.68%, 0.54% and 0.12% among those of 55 years and over and 0.89%, 0.69% and 0.17% in 65 years and over, respectively. Analysis from single factor logistic regression showed that age and education but not gender were closely related to the occurrence of AD. On the contrary, age, hypertension and stroke were closely related to the occurrence of VD.
CONCLUSIONThe incidence of dementia in the "Xi' an cohort" was similar to that being reported from other countries. AD and VD were an age-related diseases but education seemed to have had great protective effect while lack of formal education served as risk factor to AD.
