AIM: To investigate whether hypercapnia is protective against acute lung injury (ALI) in a rabbit model, and study it's potential mechanisms. METHODS: Twenty-two healthy New Zealand white rabbits were involved in this study, and randomly allocated to control group (group C), normocapnic group (group N) and hypercapnic group (group H). Oleic acid (0 1 mL/kg) was injected intravenously to establish ALI model. Lung mechanics, hemodynamics, blood-gas analysis, the content of malondialdehyde (MDA) and superoxide dismutase (SOD) activity in lung tissue were measured. Apoptosis was analyzed after 3h mechanical ventilation. RESULTS: (1) Peak airway pressure in group H was significantly lower than that in group N (P

Objective To improve the diagnosis and treatment of testicular masses associated with congenital adrenal hyperplasia(CAH).Methods A 25-year-old man presented with bilateral testicular nodules.Physical examination revealed palpable multiple nodules in the bilateral testes and epididymides as well as enlarged and hard right testis with uneven surface.Biochemical examination showed testosterone(T) of 18.7 nmol/L,17?-(OH)P＞20.0 ng/ml,positive results of rapid ACTH stimulation test and dexametha- sone suppression test.B-ultrasound demonstrated diffuse testicular lesions with nodules in parts of the bilater- al testes.Bilateral testicular nodules were biopsied,and pathological diagnosis was interstitial cell hyperplasi- a.Positive staining for?-inhibin was observed immunohistochemically.The clinical characteristics of testicular masses associated with CAH were reviewed in combination with the literature.Results Based on medical history,imaging,laboratory and pathologic examinations,the patient was diagnosed with testicular masses as- sociated with CAH.He received oral cortisol at dose of 40 mg daily for 2 weeks,and then at dose of 30 mg daily as maintenance therapy.After treatment of 8 months,B-ultrasound showed complete regression of the testicular tumors.Follow-up of 24 months showed no recurrence of the tumor.Conclusions For patient with bilateral testicular masses,endocrinological evaluation and clinical history taking are indicated to exclude testicular interstitial cell hyperplasia associated with CAH.By oral steroid replacement therapy,hormone-sen- sitive testicular masses can regress.

Objective To investigate the protective effects of hypereapnia on acute lung injury(ALI)in an model of rabbits in vivo,and to observe its effect on oxygen free radicals in the lung tissue in order to uncover the potential mechanisms.Method In the laboratory of pharmacology,China Medical Univereity,twenty-two healthy New Zealand white rabbits were randomly assigned to control group(Group C,n=6)with the injection of normal saline(0.1 ml/kg),and sixteen rabbits were injected with oleic acid(0.1ml/kg)intravenously,and then were randomly dirided into normocapnia group(Group N,n=8)and hypercapnia group(Group H,n=8,FiCO2=8%).Then tracheostomy was performed,and the experimental animals were ventilated for 3 hours after oleic acid or sterile normal saline administration.Lung mechanics,hemodynamics,blood-gas analysis were monitored.The rabbits were exsangninated.and the lungs and heart were taken out from the thorax.The concentration of superoxide dismutase(SOD)and malondialdehyde(MDA)in the lung tissue were assayed.Lung tissue wet/dry ratio and pulmonary permeability index were measured and histologic damage was assessed after three hours'mechanical ventilation.Results Peak airway pressure in Group H was significantly lower than that in Group N and the dynamic lung comphance Was significantly higher than that in Group N(P＜0.05).PaO2 in Group H was significantly higher than that in Group N(P＜0.05).The concentration of MDA in the lung tissue in group H was significantly lower than that in Group N(P＜0.05),and SOD in group H was significantly higher than that in Group N(P＜O.05).Lung tissue wet/dry ratio and pulmonary permeability in group H were significantly lower than that in Group N(P＜0.05).Histological tissus damage in Group N wassignificantly severer than that in Group H.Conclusions Hypercapnia induced by inhalation of high concentration of carbon dioxide(8%)plays protective role in this in vivo model of ALI.The mechanisms may be associated with enhanced SOD activity and the attenuation of lipid peroxidation in the lung tissue.

ObjectiveTo study the protection of Chinese herbs on the ischemic brain of rats. Methods 75 Wistar rats were divided into 5 groups, Group 1 for false operation. For the other four groups, the common carotid artery was exposed then was ligatured and cut off, Group 2 for model. From the 20th hour after operation on,Group 3, 4, 5 were fed with complex prescription of Chinese medicine named Prescription 1, 2 and 3 once a day respectively. 3 hours after taking medicine, Groups 2-5 were put in the hypoxia environment for 1 hours, then taking the medicine for 7 days. On the 7th day after operation,the blood was taken from R. atria then the rats were killed and the whole right brains were cut off. Malonaldehyde (MDA), notric oxide synthetase (NOS) and superoxide dismutase (SOD) in the brain tissue and serum, and calcium in the brain were measured respectively. ResultsThe three prescriptions can decrease the quantity of MDA both in brain tissue and serum and the calcium in brain tissue(P<0.05-0.001).Prescription 1 can enhance the activity of SOD in brain tissue while the others can decrease the activity of NOS. The hippocampus cells show tidy, and the number of the necrotic cells decrease greatly among them, Groups 4 and 5 are better than Group 3.Conclusions Prescriptions 1-3 can protect the brain tissue of the rat form ischemic brain injury.

Objective To investigate the expression of osteopontin(OPN)and osteonectin(ON) in breast cancer and its relationship with formation of microcalcification.Methods Acoording to the number of microcalcification of breast cancer in mammography,93 cases were divided into three groups:non- microcalcification group,little microcalcification group,and much microcalcification group.The relationship between expression of OPN\ON and microcalcification was studied.At the same time,breast cancer with microcalcification was observed in 3 cases by using patho-histological method and transmission electron microscopy(TEM).Results Microcalcification was detected not only in necrosis foci,but also in nest of breast cancer without necrosis.Microcalcification was found in intracytoplasm of breast cancer cells through TEM.Expression of OPN\ON was significant related with the presence and number of microcalcification. There was obviously different expression between microcalcification group and non-microcalcification group (x~2=11.454,5.540,P

Objective To investigate the effect and significance of microglia/macrophage activation prior to cerebral ischemic preconditioning (CIP) in regulating toll-like receptors 2 (TLR2)/nuclear factor-kappa B (NF-κB) inflammatory signaling pathway in early stage after ischemic brain injury in rats.Methods Thirty healthy male SD rats were selected and divided into normal control group,sham operation group,ischemia group,intervention group and treatment group according to random number table,with six rats per group.A rat model of focal permanent cerebral infarct was established by occlusion of middle cerebral artery (MCAO).CIP was performed by local ischemia-reperfusion.Minocycline was used to inhibit microglia/macrophage activation after CIP.Features of microglia/macrophage activation after CIP were detected by immunofluorescence; mRNA expressions of predominant factors (NF-κB inhibitor α,IκB-α;tumor necrosis factor α,TNF-α) of TLR2/NF-κB inflammatory signaling pathway in parietal cerebral cortex by in situ hybridization method; death rate by Kaplan-meier survival curves; neurological deficits by a 5-point neurological scale; brain infarct size by triphenyl tetrazolium chloride (TTC) staining.Results Microglia/macrophage started activation at one hour after cerebral ischemic injury in preconditioning group and presented a significant increase at 12 hours.Speed and range of activation were higher in preconditioning group than in ischemic group.IκB-α mRNA in preconditioning group started expression at one hour.TNF-α mRNA in preconditioning group remained a low expression in 12 hours and had a significantly lower peak value as compared with that in ischemic group (P ＜ 0.05).CIP increased rat survival rate significantly,improved nerve function and reduced infarction size when compared with the ischemia group (P ＜ 0.05).Minocycline inhibited nerve protection by CIP significantly (P ＜0.05).Conclusion CIP induces rapid activation of microglia/macrophage in early period of rat cerebral ischemic injury and provides brain protection probably via inhibition of TLR2/NF-κB activity and inflammatory overreaction to cerebral ischemia.

This study investigated the "homing" phenomenon in hepatocellular carcinoma (HCC). The "homing" specificity of endothelial progenitor cells (EPC) by establishing an orthotopic implantation model in nude mice. EPCs harvested from the marrow cells were separated by density gradient centrifugation. Fluorescence microscope, flow cytometry (FCM) and double fluorescence staining with FITC-UEA-I and DiI-ac-LDL, were employed to identify the cells. 4',6-diamidino-2-phenylindole (DAPI) labelling and real-time PCR were used for detecting the expression of CD133 and chemokines to trace and observe the distribution of EPCs. Our results showed that the distribution rate of EPCs was obviously higher than that in other important organs and the negative control group. Detection of CD133 and chemokines yielded similar results in difference tissues. Our experiment confirmed that the chemotaxis of EPCs does exist in HCC. Moreover, HIF-1α, SDF-1 and VEGF might play important roles in the "homing" of EPCs in HCC. EPCs might be a potential candidate for targeting vector of HCC for gene therapy.
