OBJECTIVETo summarize the clinical characteristics of severe acute respiratory syndrome (SARS) and observe the therapeutic effect with integrative Chinese and western medicine (ICWM) approach in treating patients with SARS.

METHODSForty-eight patients selected from the authors' hospital, whose diagnosis confirmed as SARS were analysed to sum-up the diagnostic type and basic feature of patients and the chief clinical characteristics. All the patients were randomly divided into the trial group and the control group, 24 in each. The control group was treated with the western medical therapeutic program and the trial group was treated with ICWM therapeutic program. The differences between the two groups were compared in terms of development of illness, time of using corticosteroid and absorption time of pulmonary inflammatory lesion, etc.

RESULTSMost patients were youth and adult aged between 18 to 40 years old, the initial symptom was mainly the high fever, accompanied with general soreness, chest stuffiness and cough, etc. The hospitalization time, body temperature fluctuation sustaining time and time of using corticosteroid in the trial group were shorter than those in the control group, showing significant difference (P < 0.05). ICWM treatment showed a better effect in defervescence and inflammatory lesion absorption time, but with no statistical significance.

CONCLUSIONPatients of SARS are mainly youth and adults in the prime of life, fever always appears as the initiation of illness and some accompanying symptoms would appear. As compared with the western treatment, ICWM treatment could evidently shorten the course of illness, prevent the rebounding of fever and reduce the time of using corticosteroid.

Background Glial cells perform specialized function in many aspects of the development,homeostasis,and function of neurons.Retinal ganglion cells (RGCs)and glia interactions are critically important in glaucomatous neurodegeneration.However,the precise mechanisms of glial activation and ganglion cells damage are still remained unclear. Objective This study was to assess the early responses of glial cells in the retina,optic nerve and optic chiasm in rat models of acute high intraocular pressure (IOP),and to examine the expression of nestin,a neuronal progenitor marker,in the reactive glias. Methods Acute high IOP of 110 mmHg was induced in the right eyes of 6 clean adult female Wistar rats by infusing normal saline solution into the anterior chamber for 60 minutes.Three normal matched Wistar rats were used as controls.The rats were sacrificed by overanaesthesia and sections of retina,optic nerve and optic chiasm were collected on 3 days and 7 days after the injection.Rat retina was examined by Nissl staining to illustrate the gross structure changes.Loss of axons of RGCs in the optic nerve was assessed by immunostaining of β Ⅲ-tubulin.Double labeling of glia] fibrillary acidic protein (GFAP) and nestin was performed in sections of retina,optic nerve and optic chiasm to evaluate the glial responses.The use of the animals complied with Statement of Animal Ethic Committee of Peking University Third Hospital. Results In control rats,GFAP-positive glial cells were observed in the retina,optic nerve and optic chiasm,where only weak positive response for nestin was noticed.Three days after acute IOP elevation,thickness of inner plexus form layer was significantlydecreased in comparison with the control rats.A loss of 46％ RGCs was found in the rats with ocular hypertension.Obvious increase of GFAP expression was displayed in the retina,and processes of GFAP-positive glia cells extended into outer retina accompanied with significant up regulation of nestin.Axons in the optic nerve demonstrated a tendency of degeneration.Nestin expression increased significantly in the GFAP-positive glias in the optic nerve.Cross-sectional area of optic chiasm corresponding to the injured retina decreased relative to its countcrpart.Astrocyte like GFAP and nestin-colabeled glials were observed in this part of optic chiasm.The pathological changes of the retina,optic nerve and optic chiasm in hypertensive eyes aggravated on 7 days. Conclusions Acute ocular hypertension induce early onset of RGCs loss and axon degeneration.Neuronal injury is accompanied with glial reaction.Reactive glial cells express neuronal progenitor markers.The structural changes of the optic nerve and optic chiasm occur simultaneously with the high IOP.

OBJECTIVETo investigate the effects of co-exposure of LPS and heat on TNF-alpha expression in rat kidneys.

METHODSMale pathogen-free Wistar rats were randomly assigned in saline-injected normothermic control (C group), saline-injected heat exposure (H group), LPS-injected normothermic control (L group), and LPS-injected heat exposure (HL group). The rats in H and HL groups were exposed in a chamber at an ambient dry bulb temperature (Tdb) of 35.0-/+0.5 degrees, and those in C and L groups were exposed to a Tdb of 26-/+0.5 degrees. The rats in L and HL groups were given an intravenous injection of LPS (10 mg/kg) via the tail vein to induce endotoxemia, and equivalent normal saline was injected in C and H groups. TNF-alpha expression in the kidney was detected by immunohistochemical SABC method, and the renal damage was evaluated histologically at 120 min after the treatment.

RESULTSCo-exposure of the rats with LPS and heat caused significantly enhanced TNF-alpha expression and histopathological damage in the kidneys.

CONCLUSIONLPS combined with heat exposure causes renal toxicity, while is closely associated with the expression of TNF-alpha in the kidneys.
