Objective To investigate the diagnosis and treatment outcomes of testieulax endodermal sinus tumor. Methods Twenty-four cases diagnosed with testieular endodermal sinus tumors from November 1996 to April 2007 were retruspeetively reviewed. Eighteen patients presented with stage Ⅰ disease, 4 presented with stage Ⅰ , and 2 presented with stage Ⅲ. Inguinal radical or-chieetomy were performed in all patients. Retroperitoneal lymph node dissection was performed in 8 ea-ses. Results The histological structures were rather complicated in 24 tumors. Twenty-three eases (96%) were found with reticular pattern, 22(92%) with hyaline body, 20(83%) with glandlike structure, 16(67%) with Shiller-Dural body, and 13(54%) with solid formation. The former 3 kinds were regarded as the main diagnostic criteria. Twenty-one eases were followed up for 20 months to 12 years. During the follow-up, 2 patients died of the disease. Condesions Early diagnosis and combi-nation therapy, including radical orehieetomy and chemotherapy, are the keys to improve the curative effect of testieular endodermal sinus tumors. Active surveillance of AFP is critical for monitoring the recurrence and metastasis of this tumor.

AIM: To study the regulatory effect of curcumin on expression of heme oxygenase-1 (HO-1) in the lung of rat treated with LPS. METHODS: Eighteen rats were divided into three groups injected with different agents via lingua vein: control group (animals received equivalent saline) , LPS group (animals received a bolus dose of LPS 5 mg?0.5 mL-1?kg-1) and LPS+ curcumin group (animals received AP- 1 inhibitor curcumin 20 mg?0.5 mL-1?kg-120 min before the injection of LPS 5 mg ?0.5 mL-1?kg-1) . The expression of HO-1 mRNA and protein in the lung were examined 7 h after LPS administration by reverse transcribed polymerase chain reaction (RT- PCR) and Western blotting, respectively. Carboxyhemoglobin (HbCO) formation within pulmonary tissue was measured to represent CO content. RESULTS: The results showed that HO- 1 mRNA and protein expression as well as CO content in the lung of rats in LPS group were significantly higher than those in control group (P

AIM To investigate the improving effects of epigallocatechin gallate (EGCG) on rat kidney injury induced by cisplatin and its mechanism of action.METHODS Fifty male SD rats (10 rats/group) were randomly divided into blank control group,kidney injury group,EGCG low-,middle-and high-dose (25,50 and 100 mg/kg) groups.The kidney injury group and the drug administration group were treated with 7.5 mg/kg cisplatin by intraperitoneal injection to build the kidney injury model,and the blank control group was intraperitoneally injected with normal saline.After fourteen days of administration,the general condition and morphological changes of kidney tissue by HE staining were observed;BUN,Cr,Cys-c contents in serum,and IL-18,KIM-1 contents in urine were detected by ELISA;MDA,GSH and T-SOD contents in renal cortex were determined by kit;Western blot method was used to determine the contents of Nrf2 protein in renal contex cytoplasm and nucleus,and the expression level of HO-1 protein.RESULTS EGCG intervention could improve the pathological structural changes of rat kidney injury induced by cisplatin,decrease kidney index,and decrease serum Cr,Cys-c contents and urine IL-18,KIM-1 contents.Moreover,renal cortex MDA concentration decreased,and renal cortex GSH concentration,T-SOD activity increased.At the same time,renal cortex cytoplasm Nrf2 content reduced,but nucleus Nrf2 and total cell HO-1 contents increased.CONCLUSION EGCG plays a role in the improvement of rat kidney injury induced by cisplatin through the activation of Nrf2/HO-1 signal pathway.

Objective To investigate the clinical and head CT imageological features features in 276 cases of intracranial tubercu‐losis .Methods The clinical and CT features in 276 inpatients with confirmed intracranial tuberculosis were analyzed .Results These 276 cases of intracranial tuberculosis all were complicated by pulmonary tuberculosis ,among them blood‐borne type accoun‐ted for 49 .6% ; young and middle‐aged cases were predominant (72 .5% ) ; the majority manifested by the symptoms of fever (70 .0% ) and headache(66 .2% ) ;the summer and autumn had the higher incidence rate ,which were 167 cases(80 .7% ) .The posi‐tive detection rate of head CT plain scanning was 63 .4% ,which of enhanced scanning was 98 .6% .Among them ,236(85 .5% ) cases were tuberculous meningitis lesions ,158 cases(57 .2% ) were tuberculous encephalitis ,144 cases (52 .2% ) were tuberculoma and 133 cases (48 .2% ) were tuberculous vasculitis .Conclusion The clinical menifestations of intracranial tuberculosis are atypical ,but the head CT plain scannig displays multiple abnormalities .Moreover ,the enhanced scanning increases the positive detection rate . The lesions of meninges ,brain vessels and brain parenchyma often occur together .Therefore ,the diagnosis basis should be combined with clinic ,laboratory tests and head CT ,especially the clinical application of head CT enhanced scanning should be paid attention to .
