1.Antiapoptotic Interventions in Intracerebrai Hemorrhage
International Journal of Cerebrovascular Diseases 2006;0(11):-
Tne secondary injury may occur in the perihematomal tissue after intracerebral hemorrhage(ICH).Studies have suggested that apoptosis palys an important role in the secondary injury after intracerebral hemorrhage.1he inhibition of apoptosis may significantly improve the neurological deficit after ICH.

Pregnant women with subacute thyroiditis (SAT) are rare.One case was reported and the clinical features and management principles of SAT during pregnancy were reviewed.In pregnant women with SAT,the illness is usually not serious.If subclinical or clinical hypothyroidism develops,L-T4 must be given and thyroid function be monitored routinely,and the medication be adjusted carefully to ensure the maternal-fetal safety.

Objective:To observe the effects of rosiglitazone on transforming growth factor-?1(TGF-?1)/SMADs signal pathway in dia- betic rat myoeardium(DM)and cardiac remodeling. Methods:Thirty male SD rats were randomly divided into normal control,DM and rosiglitazone groups,each having 10 rats.Diabetic rats were induced by a single intrapefitoneal injection of streptozotoein(60mg/kg).A cannula connected to a trans- ducer was inserted into the heart to measure the cardiac function.The body weight,heart weight and heart weight/body weight (HW/BW)were measured.The ultrastruetural changes were evaluated by electron microscope and collagen content was assessed by Van Gieson staining.The mRNA expression level of SMAD3 and SMAD7 were determined by RT-PCR.The protein level of TGF-?1,SMAD3 and SMAD7 were detected by immunohistochemistry. Results:Compared with the normal controls,diabetic rats experienced marked myocardium damage.Cardiac function,espe- cially diastolic function was impaired,HW/BW(P

Objective To explore the diagnosis and treatment of abdominal cocoon. Methods The clinical data of 16 patients with abdominal cocoon were analyzed retrospectively . Result All the 16 patients with abdominal cocoon were treated and confirmed by operation. Before operation, 11 patients were misdiagnosed as mechanical intestinal obstruction, 4 as chronic appendicitis, and 1 as abdominal tumor.All patients were operated on and postoperative complications were found in 2 patients. All patients were curred clinically and followed up for 1-10years. 2 patients were died of relapsing intestinal obstruction 1,5 years after operation. 2 occurred relapsing incomplete intestinal obstruction accompaning with malnutrition, 12 patients were good during the follow up period. Conclusions Preoperative diagnosis of abdominal cocoon is difficult. The diagnosis mainly depends on the upper gastrointestinal radiography, B-ultrasonography and CT. Removal of the membrane and releasing the intestine adhesions is an effective method in treating this disease.

SWI/SNF is an ATP-dependent chromatin remodeling complex .ARID1 A gene is an important subunit of SWI/SNF complex and its dysfunction can cause abnormal chromatin remodeling , resulting in tumorigenesis .AR-ID1A occurs frequently low expression or deletion mutation in a variety of malignant tumors , such as ovarian canc-er, liver cancer, breast cancer, stomach cancer, lung cancer and so on, which indicates that ARID1A is an impor-tant tumor suppressor gene .

OBJECTIVE To investigate the effect of microRNA-129(miR-129)expression on malignant phenotypes of esophageal squamous cell cancer(ESCC) cells and its possible molecular mechanisms. METHODS The constructed miR-129-overexpressed vector (pGCMV/EGFP/miR-129) and negative control vector (pGCMV/EGFP/miR-NC) were stably transfected into ESCC cell lines (Eca109 and EC9706),respectively. Quantitative real-time PCR(qRT-PCR)was performed to detect the expression of miR-129. MTT and flow cytometry(FCM)assays were performed to analyze the effects of miR-129 on proliferation, cell cycle and apoptosis of ESCC cells. Furthermore,a luciferase reporter vector with the putative B-cell lymphoma-2(Bcl-2)3′-untranslated region(pLUC/Bcl-2-3′-UTR-wt and pLUC/Bcl-2-3′-UTR-mut)was constructed to explore whether Bcl-2 was a direct target gene of miR-129 by detecting luciferase activity. Next,Western blotting was performed to detect the expression of Bcl-2, cleaved caspase 3 and total caspase 3 proteins. RESULTS Overexpression of miR-129 significantly inhibited proliferation(P<0.01),induced cell arrest in G0/G1 phase(P<0.05)and enhanced apoptosis (P<0.05)in ESCC cells. Luciferase reporter assay indicated that Bcl-2 was identified as a direct target gene of miR-129. Results of Western blotting showed that overexpression of miR-129 significantly reduced the expression of Bcl-2 protein and increased the expression of cleaved caspase 3 protein,but induced no changes in total caspase 3 protein in ESCC cells. CONCLUSION miR-129 functions as a tumor suppressor in ESCC cells by targeting Bcl-2 gene. Therefore,miR-129 will be a potential molecular target for the treatment of human ESCC.

Anhedonia is the loss of pleasure or lack of reaction to pleasurable stimuli, which is a promising phenotype of depression. In order to explore the potential biological mechanism, the recent ad?vances were summarized from researches focused on depression with anhedonia from neuroanatomy,inflamma?tion and immunology,and molecular genetics. The structural and functional brain imaging showed that the ac?tivity in reward?related brain regions of the depressive disorder with an anhedonia was changed during re?ward?related tasks.In addition,some other genetic studies based on the related neurotransmitter,such as do?pamine, together with the findings from the researches on immunological inflammation, may shed light on finding the potential targets for novel antidepressants,besides the 5?HT.
