0.05).Conclusion SjvO_2 and OEF may objectively reflect brain oxygen metabolism and cerebral blood flow after acute cerebral infarction. Furthermore, they are valuable indicators for predicting prognosis.

This paper emphasizes constitution factor,the chief pathogenesis of repeated respiratory tract infection(RRI) of children;the main pathogenesis are Qi deficiency of spleen-lung and retention of phlegm.According to children's physiology feature,spleen is frequently insufficient and RRI Children are given too much antibiotic and bitter-cold herbs,that causes damage to stomach.Regulating spleen is expected to figure prominently in prevention and treatment of RRI children.Regulating spleen not only means reinforcing the spleen,but also promoting digestion to eliminate stagnation and regulating Qi and eliminating phlegm to restore the normal physiological function of spleen and stomach,strengthen children's constitution and immunity.There are 4 therapeutic principles of RRI children: activating spleen,promoting lung and resolving phlegm during the acute phase;reinforcing the spleen,eliminating stagnation and eliminating phlegm;reinforcing the spleen and promoting lung during the deferment period;reinforcing the spleen and enriching Qi for prevention.

Objective To investigate the clinical characteristics and diagnosis of some patients with cryptococcus neoformans meningitis(CNM).Methods The clinical features were analyzed and summarized for the findings of 16 CNM cases.Results The clinical cachexia manifestations were not found in the 16 CNM cases.The higher intracranial hypertension and the slight elevation of CSF protein content were found in the earlier period.The cryptococcus neoformans could be found in CSF through lots of lumbar puncture usually.Conclusion The symptom in the earlier period of cryptococcus neoformans meningitis is not typical.It is difficult to find the cryptococcus neoformans.In order to definite the diagnosis,more examinations of CSF must be done.

Objective In order to control the organic pollution in surface water sources in Jiaxing area, deep water treatment method was applied to treat drinking water. The effectiveness and correlative hygiene issues of the constructive project were pre,assessed. Methods On the basis of selecting and comparing some water factories in domestic and abroad which were similar with this constructive project, the assessment was synthetically carried out by surveying on the spot, checking blueprint, examining technological process and equipments layout, worked technique and materials, after experimental deep water,treatment was pup in to pilot scale test. Results The drinking water deep treatment method could eliminate organic substances effectively from original water. The results of the pilot test showed that the removed rates of CODMn, TOC, color degree and NH3,N through this measure were respectively 95.57%, 25.35%, 32.80% and 37.40% higher than those through route drinking water treatment measures. The measure could translate Ames test result into negative. The dosage of alum and chlorine could be reduced 33% and 50% respectively. Water purity and taste could be improved. The arrangement and layout of the facilities of this constructive project was advanced and reasonable, which was conformed to the hygienic requirements. Conclusion This constructive project could effectively solve the serious pollution problem of organic substances in water source in Jiaxing area and improve the purification effectiveness of drinking water and water quality. The occupational hazards that possibly present in the productive process of this project could be prevented. From the view of hygiene, this constructive project was feasible.

Objective To explore the effects of osteoblasts on the recovery of hematopoiesis and angiogenesis in acute irradiation injury mice.Methods The femurs of 18 male BALB/c mice were used to prepare the bone marrow osteoblasts, and the rest mice were divided into 3 groups as normal group, saline group and osteoblast group.The mice in normal group received no treatment, and the other two groups were received 6.0 Gy 60Co γ-ray irradiation.After irradiation each mouse of osteoblast group was administered with 2 × 106 osteoblasts through tail vein injection, and equal volume saline was given to each mouse of saline group by the same way.The following factors were measured at 7, 14, 21 d after irradiation, they were the counts of peripheral blood cells and bone marrow mononuclear cells ( BMMNC ) , the percentage of CD34 + cells in BMMNC, the histology changes and micro vascular density (MVD) of bone marrow tissue.Results The counts of peripheral blood cells, BMMNC and hematopoietic tissue area in osteoblast group were higher than those in saline group.The percentage of CD34 + cells in BMMNC and the MVD of bone marrow in osteoblast group were also higher than those in saline group at 7, 14, 21 d after irradiation ( t = 2.46 - 64.51, P ＜ 0.05 ).Conclusions Osteoblasts could significantly promote the recovery of hematopoiesis and angiogenesis in mice after acute irradiation injury.

Objective To present the authors' initial experience of treating auricular arteriovenous malformations (AVMs) with ethanol embolization and to assess the clinical effectiveness of this therapeutic method. Methods Twenty-two patients with AVMs were enrolled in this study. Through local puncturing or super-selective catheterization the absolute ethanol, or diluted alcohol (based on the pattern of the AVMs), was manually injected into the abnormal vascular plexus of the auricular lesion. The clinical results were estimated with physical examination or angiography at intervals of 3 ～ 4 month, and telephone questionnaire was made at monthly intervals for all patients. Results Thirty-eight ethanol embolization procedures were performed, the amount of ethanol used during the procedure ranged from 4 ml to 65 ml. After the treatment the clinical symptoms were improved, which were manifested as healing of the ulceration, stop of bleeding, disappearing or alleviation of tinnitus. Angiographic examination showed that the abnormal vascular lesion was completely vanished in 9 cases, decreased by 50% -75% in 8 cases and decreased less than 50% in remaining 5 cases. The common complications included irreversible local necrosis and vesiculation. Conclusion For the treatment of auricular AVMs ethanol embolization is an effective and safe method, which might become the therapy of first choice.

Objective To investigate the effect of penehyclidine (PHCD) on Toll-like receptor 4 (TLR4)mRNA and Toll-like receptor 2 (TLR2) mRNA expression in the lung tissue in rats with acute lung injury induced by lipopolysaccharide (LPS) .Methods Sixty healthy SD rats of both sexes weighing 200-220 g were randomly divided into 5 groups ( n = 12 each) :control group (group C) , LPS group and P1-3 groups. Acute lung injury was induced by intraperitoneal (IP) LPS 8 mg/kg in LPS and P1-3 groups. PHCD 0.3, 1.0 and 3.0 mg/kg were given IP after LPS administration in P1-3 groups. The animals were anesthetized at 6 h after IP LPS. Blood samples were collected for determination of serum TNF-α and IL-6 concentrations ( by ELISA) and then sacrificed, the lungs were immediately removed for determination of TLR4 mRNA and TLR2 mRNA expression (by RT-PCR), and microscopic examination. Results LPS significantly increased TLR4 mRNA and TLR2 mRNA expression in the lung tissue and serum TNF-α and IL-6 concentrations. PHCD 1.0 or 3.0 mg/kg significantly inhibited LPS-induced increase in TLR4 mRNA and TLR2 mRNA expression in the lung tissue and serum TNF-α and ILr6 concentrations.The lung histopathologic damage was significantly ameliorated in P2 and P3 groups as compared with group LPS.Conclusion PHCD can protect the lungs against LPS-induced acute lung injury through inhibiting TLR4 mRNA and TLR2 mRNA expression in the lung tissue and reducing the inflammatory response.

Objective To observe any changes in spinal cord hemodynamics after spinal cord injury and to investigate their mechanism. Methods Twenty female Sprague-Dawley rats were divided into a control group and a moderate injury group,10 rats in each group.A rat model of spinal cord injury caused by moderate compression was established using Nystrom's method.Changes in the velocity and volume of blood flow and in the diameters of vessels of the spinal cord were monitored for 6 hours using laser speckle imaging. Results No changes in the velocity or volume of blood flow or in the diameter of vessels were observed in the control group,but all of these indices diminished significantly in the injury group. Conclusions Laser speckle imaging can be used to monitor changes in spinal cord hemodynamics.Such changes after acute spinal cord injury indicate progressive post-injury ischemia.The occlusion of veins may be an important contributor to post-injury ischemia.
