Objective To study clinical features and its diagnosis and treatment of alcoholic cirrhosis.Methods 68 cases with alcoholic cirrhosis were retrospectively analyzed,with cirrhosis from hepatitis B as control.Results Alcoholic cirrhosis accounted for 8.5% of in-patient cirrhosis in the correspomding period,mean age being(53.5?14.6),and with more than 135g alcohol intake per day which persisted over 10 years.Such signs significantly increased as dark complexion,liver palms,spider naevi,hepatomegaly,ynecomastia,hypertrophy of parotid gland,?-glutamyltansferase(GGT),ratio of aspartate aminotransferase(AST) to alanine aminotransferase(ALT),mean corpuscular volume(MCV),uric acid(UA),serum ferritin(SF) rose apparently,usually combined with hepatogenic diabetes,peptic ulcer,hyperuricemia,hyperlipemia.Peculiar complication were alcohol withdrawal syndrome,gort,gouty arthritis,aseptic necrosis of femur.Among them,53 cases(77.9%) improved clinically,9 cases(13.2%) showed no effect,6 cases(8.8%) died.Conclusions Occurrence of dark complexion,liver palms,spider naevi,hepatomegaly,ynecomastia,hypertrophy of parotid gland and test of GGT,AST/ALT,MCV,UA,SF are helpful to clinic and differentiation diagnosis of alcoholic cirrhosis,abstinence are not able to prevent its development.Long-term therapy aiming at endotoxin toxemia might improve prognosis of alcoholic cirrhosis.

Objective To construct prokaryotic cell expression vector of human Eotaxin mutants.Methods By point mutation,eight amino acid residues in the N-terminal(residues of 3-7)and N-loop(residue 14)regions of Eotaxin were individually mutated to methionine and residue 14 was delleted or methiomine was inserted after the residue 14,and then cloned respectively into prokaryotic cell expression vector-PET30a+.Results Eight N-terminal and N-loop mutants of human Eotaxin and their prokaryotic cell expression vector-PET30a+ were gained.Conclusion The successful construction of prokaryotic cell expression vector of human Eotaxin mutants lays a foundation for their expression and biological activity and for filtering antagonists of CCR3.

The afferent connections to the periaqueductal gray in the rat were examined by means of retrograde axonal transport method using horseradish peroxidase (HRP).The microinjection syringe needle or micro-electrophoretic pipette was inserted stereotaxically by an oblique approach through the cerebellum. HRP was introduced into the dorsal, lateral, ventrolateral areas of periaqueductal gray or periventricular gray of ventriculus Ⅲ at posterior commissure level respectively.The results were as follows:1. Injections of HRP in the dorsal area of periaqueductal gray(PAG).Numerous labeled cells were consistently found in the paraventricular nucleus, dorsomedial and ventromedial hypothalamic nuclei, posterior hypothalamic nucleus, medial mamillary nucleus, zona incerta, lateral and ventral nuclei of periaqueductal gray, superior colliculus, inferior colliculus, dorsal raphe nucleus and periventricular gray of ventriculus Ⅳ. In some cases, a smaller number of cells was found in the zona reticulata of the substantia nigra, and lateral hypothalamic nucleus. In one case, the enzyme was injected into the dorsal area of PAG, which diffused to the superior and inferior colliculi, resulted in labeling of Forel's field and reticular nucleus of thalamus.2. Injection of HRP in the lateral area of PAG.HRP-positive cells were observed within the bed nucleus of the stria terminalis, paraventricular nucleus, anterior hypothalamic nucleus, ventro-medial hypothalamic nucleus, medial thalamic nucleus, nucleus interstitialis magnocellularis, commissural posteriors, zona incerta, ventral nucleus of PAG, zona reticulata of substantia nigra, formatio reticularis of mesencephalon, dorsal raphe nucleus, and periventricular gray of ventriculus Ⅲ and Ⅳ. In some cases, a small number of cells was found in the supraoptic nucleus, superior and inferior colliculi.3. Injection of HRP in the ventrolateral area of PAG.In all cases the greatest number of HRP-positive neurons was shown in the supraoptic nucleus, paraventricular nucleus, periventricular gray of ventriculus Ⅲ, lateral nucleus of PAG, zona reticulata of substantia nigra, dorsal raphe nucleus and locus coeruleus. The labeled cells were mainly located ipsilaterally. But the labeling of supraoptic nucleus was observed bilaterally. In one case the enzyme diffused to the reticular formation, a smaller number of cells was found in nucleus cuneifomis and mesencephalic reticular formation of more caudal position.4. Injection of HRP in the periventricular gray of ventriculus Ⅲ.Following the injections of HRP in the periventricular gray of ventriculus Ⅲ, numerous HRP-positive cells were consistently observed in the bed nucleus of the stria terminalis, supraoptic nucleus, paraventricular nucleus, ventromedial nucleus of hypothalamus, medial nucleus pars medialis of thalamus, zona incerta, ventral nucleus of PAG, zona reticulata of substantia nigra, dorsal raphe nucleus and locus coeruleus.

This paper is the first to report skin infection of baby panda caused by Trichophyton gy-pseum, Chorioptes panda and Demodex ailuropodae. The clinical manifestation and laboratory examination of this disease were also reported. We took a comprehensive measure for the prevention and treatment of this disease. Marked efficacy was obtained

0% Azone. Conclusion Azone can promote the transdermal absorption of the Matrine in Compound Kushen Gelatum. The effect of promoting penetration of 2% Azone is the best.

OBJECTIVE:To explore the protective effect of the extracts from Radix et Rhizoma Rhei and Alisma orientalis against acute kidney injury induced by diethylene glycol (DEG) and its action mechanism. METHODS: The acute kidney injury model of mice was induced by intragastric administration of DEG. Then the model mice were administered intragastrically with the extracts of Radix et Rhizoma Rhei and Alisma orientalis. Serum levels of creatinine(Cr) and blood urea nitrogen (BUN), the activities of superoxide dismutase (SOD) and glutathione peroxidase(GSH-PX) and the content of malonaldehyde(MDA) were determined. RESULTS: After administration of DEG, the mice presents with obvious toxic reactions including the increase of the ratio of kidney to body weight, the increase of serum levels of BUN and Cr, the decrease of the activities of SOD and GSH-PX in kidney tissue, the increase of the content of MDA. However, after treatment with the extracts of Radix et Rhizoma Rhei and Alisma orientalis, the toxic symptoms in mice were attenuated markedly, the ratio of kidney to body weight decreased, serum levels of BUN and Cr decreased significantly, the activities of SOD and GSH-PX in renal tissues increased and the content of MDA decreased. CONCLUSION: The remarkable protective effect of the extracts from Radix et Rhizoma Rhei and Alisma orientalis against DEG-induced acute kidney injury in mice might be related to its actions of improving the activity of antioxidase of kidney while inhibiting lipid peroxidation.

The present study, using the different catecholamines, observed the effects on plasminogen activator (PA) activity release in the vascular wall of rat hindlegs. The results showed that adrenaline perfusion induced the highest PA activity in three different catecholamines. Propranolol completely blocked PA activity induced by isoprenaline. PA activity induced by adrenaline or noradrenaline was completely inhibited by propranolol combined with phentolamine. During physiological stress the increase of plasma noradrenaline level was accompanied with higher PA activity. These data indicated that exogenous catecholamines produced a increase of PA activity via ?-adrenoreceptors stimulation mainly, as well as ?-receptors partially. The endogenous increase of catecholamines showed the same effect on fibrinolytie system.

Laparoscopic minimally invasive surgery technology is rapidly developing in the tumor treatment field. Due to the lack of space perception of the previous 2 D laparoscopic surgery, it has been unable to meet the current needs, and then 3 D laparoscopic technology emerged and got widely development. This paper summarizes the difference between the 3 D laparoscopic technique and traditional 2 D laparoscopic technology, and then analyzes the classification of 3 D signal display technology and common format. At the same time, this paper introduces the integration operating room structure with 3 d technology, signal format, and signal transmitting method. Finally, this paper prospected the application foreground for 3 D laparoscopic technology in the operating room.
