Objective To investigate the relationship between microtubule damage and mitochondria damage in hypoxic cardiomyocytes.Methods Cardiomyocytes from neonatal Wistar rat were isolated and cultured for 3-5 d,then divided into three groups: normal control,hypoxia(cultured in hermetic container containing 1%O_(2),5%CO_(2),95%N_(2)),hypoxia with microtubule depolymerization(by adding 4 ?mol/L colchicine).The fluorescence intensity of ?-microtubule was determined by flow cytometry,the morph and distribution of ?-microtubule and mitochondria were checked by confocal laser scanning microscopy(CLSM) at 30 min,1 h after the cadiomyocytes being oxygen deficit.Results As compared with the normal control cells,the fluorescence intensity of ?-microtubule decreased and the microtubule ruptured and distributed confusedly,and the mitochondria changed into disorder in hypoxic cells.As compared with the hypoxic cells,the distribution of mitochondria confused and the fluorescence intensity decreased in the cells of hypoxia with microtubule depolymerization.Conclusion Microtubule damage occurred at the early stage of hypoxia(30 min).Microtubule damage may lead to mitochondria damage in hypoxic cardiomyocytes.

[Objective] To explore the curative effect of Chaishao Liujunzi Decoction for Chronic Gastritis(Liver Stagnation and Spleen Deficiency Syndrome).[Method] 90 cases were allocated to 2 groups(each group 45 cases) randomly.The treatment group was treated by the Decoction,the control group by Motilium and NexiumTablets.2 weeks constituted the course of treatment.The curative effect,improvement of symptoms and signs,manifestation of endoscopy before and after treatment were observed.[Result] The curative effect in treatment group was significantly different as compared with control group after treatment(P

Positron emission tomography (PET) is a highly sensitive and low invasive technology for cancer biological imaging. Integrated PET/computed tomography (PET/CT) cameras combine functional and anatomical information in a synergistic manner that improves diagnostic interpretation. The role of 18F FDG PET/CT in differentiated thyroid cancer (DTC) is well established, particularly in patients presenting with elevated thyroglobulin (Tg) levels and negative radioactive iodine scan. This review presents the evidence supporting the use of 18F FDG PET/CT throughout the diagnosis and management of thyroid cancer, and provides suggestions for its clinical uses.

Objective To study the features of hippocampal atrophy (HA) by MRI in mild Alzheimer's disease(AD) patients. Methods Fifteen mild AD patients and 30 healthy controls were included in this study and all subjects were examined by both MRI and MMSE. The differences in the hippocampal volume between the mild AD and the control were analysed, and relationships between the hippocampal volume and age, MMSE scores were evaluated. Results The hippocampal volume of the mild AD was decreased significantly than that of the controls 〔(2 08?0 46)cm 3 vs (3 11?0 19)cm 3, t =2 71, P 0 05). Conclusions MRI-based HA could be used to differentiate the mild AD patients effectively from the healthy subjects and could also be regarded as a status marker for the early clinical diagnosis of AD.

Objective To explore the methodology of repairing secondary nasal deformity of congenital unilateral cleft lip after operation and clinical outcome of the patients. Methods The repairing operation were performed in 46 cases,in which polyterafluoroethylene (PTFE) implants were inserted into a pocket under the nasal dorsum, ala or base through a small incision. Results The flat nasal dorsa, tips and hollow nosal base were elevated. The profile view of noses was improved apparently. The outcome was satisfactory. Conclusion PTFE is a optimal plastic material,which is compatible perfectly with circumferential tissues. The outcome of filling is excellent. Therefore, this technique is one of the efficient methods to repair secondarynasal deformity of unilateral cleft lip.

Pleuritis rat model was adopted to observe the influence of Eryngium foetidun L . on in- flammatory cell factors (TNF-a, IL- 6 and NO) . The results showed that Eryngium foetidum L. can decrease the contents of TNF-a , IL- 6 and NO in serum. It is indicated that the anti- inflam- matory effect of Eryngium foetidum L. is probably related to the decrease of the contents of the above factors.

Objective To explore indications, ablated targets, efficacy and complications of microelectrode-guided thalamotomy and pallidotomy for treating Parkinson's disease(PD). Methods The clinical date of 225 PD patients underwent microelectrode guided thalamotomy and/or pallidotomg were retrospectively analyzed with UPDRS scores. Results The outcome of operation was excellent.The rate of improvement for tremor, rigidity, gait, balance and bradykinesia were 98 0%, 89 0%, 72 8%, 70 5% and 47 8% respectively. Postoperative motor UPDRS scores of both "on"/"off"states significantly decreased by 54 4% and 62 6% respectively. The frequency of post-operative complications was such as the following: bleeding caused by puncturing (0 48%),transient hiccup(6 7%), temporary dysarthria(5 5%), transient somnolence(10 0%) and mental disorder(4 5%). There were no severe and permanent complications. Conclusions The thalamotomy and/or pallidotomy guided by the microelectrode were the effective and safe method for treatment of PD, but the indications of this surgery should be well familiarize. The ablated target selection and its precise localization were of key importance for a better outcome.

Objective:To investigate the values of immunophenotype and the Collagen type1 alpha1/Proto-oncogene Proteins c-sis (COL1A1/PDGFB) fusion gene in the diagnosis of dermatofibrosarcoma protuberans (DFSP). Methods:IHC markers and the COL1A1/PDGFB fusion gene were detected by IHC staining and interphase fluorescence in situ hybridization (FISH) in 73 cases previously diagnosed as DFSP. A total of 85 and 10 non-DFSP cases were also included as controls for IHC staining and FISH, respectively. Results:In the 73 DFSP cases, the positive detection rates for immunohistochemical marker vimentin, CD34, CD99, S100, desmin and SMA were 100%, 91.78%, 61.64%, 0, 0, and 6.85%, correspondingly. Protein expression levels in these cases varied from the control group, and CD34 ex-pression was significantly different among the differential diagnoses. The positive detection rate for the COL1A1/PDGFB fusion gene was 86.96%(60/69), whereas the gene expression in the control group was negative. Conclusion:The COL1A1/PDGFB fusion gene is a highly specific and sensitive marker in the diagnosis of DFSP. CD34 is a suitable marker for DFSP.

Objective To observe the clinical efficacy of acupuncture by stages in treating post-stroke swallowing dysfunction. Method Sixty eligible patients were randomized into a staging-acupuncture group and an ordinary-acupuncture group, to respectively receive acupuncture by the stage of swallowing and ordinary acupuncture in addition to the basic treatments. Function estimation was conducted before and after intervention in both groups to compare the therapeutic efficacies.Result According to the water drinking test, the total effective rate was 83.3% in the staging-acupuncture group versus 53.3% in the ordinary-acupuncture group, and the difference was statistically significant by rank sum test (P＜0.05), and the staging-acupuncture group was superior to the ordinary-acupuncture group especially in the pharyngeal stage (P＜0.05); the differences were statistically insignificant in the oral stage and esophageal stage (P>0.05); regarding the video fluoroscopic swallowing study (VFSS), the staging-acupuncture group was significantly better than ordinary-acupuncture group in improving swallowing function (P＜0.05).Conclusion Acupuncture by swallowing stages is effective in treating post-stroke swallowing dysfunction, especially in improving the swallowing function in pharyngeal stage.
