Recent studies suggest that astrocyte elevated gene 1 ( AEG-1 ) is almost highly expressed in all types of malignant solid tumors and correlates with poor prognosis,which becomes a prognostic marker for many kinds of tumors.As a strongly basic protein,AEG-1 possesses a transmembrane domain and multiplenuclear localization signals.It is present in the cell membrane,cytoplasm and nucleus.As an oncogene,AEG-1 palys an important role in a virety of malignant biological behaviors of cancer,which range from cell proliferation,apoptosis,migration,adhesion,invasion to tumor angiogenesis and chemotherapy resistance.Its critical role in tumor genesis and progression has made it a potential therapeutic target.

[Summary] Laparoscopic sleeve gastrectomy ( LSG) as a sole and definitive bariatric surgery has achieved well results in terms of decreasing the body mass index ( BMI ) and percentage of excess weight loss (%EWL ) , therefore reducing the obesity-related complications , but the mechanism remains unclear .As a restrictive surgical procedure , the most important mechanism of LSG might be the reduction of the volume of the stomach resulting in a limited food intake .Therefore, to achieve the best weight loss after surgery , measuring the gastric volume is an indispensable technology .Currently, gastric capacity measurement methods include imaging measurements and intraoperative direct measurement . Imaging methods include upper gastrointestinal radiography , CT three-dimensional reconstruction , MRI and radionuclide scanning , with each having its advantages and disadvantages .In this article, the measurement methods of gastric capacity before and after LSG were reviewed .

Objective Evaluating the effect of Shugan-Jieyu capsule combined with pramipexole on depressive symptoms in parkinson's disease(PD) patients.MethodsAccording to the criteria of including and excluding, we collected 63 PD depression cases who visited doctors at neurological outpatient room between June 2014 and April 2016.35 cases only treated with pramipexole, designed as pramipexole group, and 28 cases treated with pramipexole and Shugan-Jieyu capsule, designed as combined treatment group.The Hamilton depression scale(HAMD), activities of daily living scale(ADL) and unified Parkinson's disease rating scale-part III(UPDRS-III) were assessed at baseling, week 6 and week 9.ResultsAt week 9, HAMD was (17.71±6.78) in pramipexole group versus (14.32±4.81) in combined treatment group, there was significant difference between the two groups(P=0.029), As for HAMDΔ9, analysis did show a significant difference(pramipexole group (-11.06±3.27) vs combined group (-14.93±6.24);P=0.002).Analysis showed a significant difference as for ADLΔ6(pramipexole group (-2.37±1.31) vs combined group (-3.57±2.04);P=0.006) at week 6.There was no significant difference between groups for the reduction in total UPDRS-III scale.No serious adverse event was recorded during treatment of depression.ConclusionShugan-Jieyu capsule combined with pramipexole did have significant effects versus pramipexole on depressive symptoms in PD patients.

NDUFS3 is an essential subunit of mitochondrial NADH:ubiquinone oxidoreductase (complex Ⅰ ) and plays a critical role in the mitochondrial typeⅠ respiration chain.Mutations in this gene are shown to cause neurodegenerative disease such as Leigh syndrome (subacute necrotizing encephalopathy).In recent years,many evidences show that the expression of NDUFS3 proteins are lower in many cancerous cells compared to the corresponding normal cells.It comes to the conclusion that NDUFS3 may play a role in the tumorigenesis.

Thioredoxin-related protein 14 (TRP14),a new member of Trx family,is a novel disulfide reductase with conservative CPDC motif.Its structure and function are comparable to Trx,which is the representative member of Trx family.However,there are many differences.When tumor necrosis factor-α (TNF-α) induced cells to produce the active oxygen,TRP14 can change oxidatin state of dynein light chain(its substrate),act as a sensor of the intracellular redox state to regulate NF-κB signaling pathways induced by TNF-α,MAPK and apoptosis signaling pathways.

Objective To detect P0.1 and respiratory function of patients with cerebral infarction(CI)and analyze the effect of cerebral infarction on respiratory function. Methods Arterial blood gases, respiratory drive and lung function were measured in 35 cases with CI and 15 healthy controls. The figures were analyzed by SPSS 10.0. Results The PaO0.2 (mm Hg, 75.80±4.12, 1 mm Hg=0.133 kPa), SaO2(%,94.97±0.78) and Plmax(kPa,4.076±2.443) were lower than those in the healthy control group (88.68±3.77, 96.40±0.48 and 7.747±0.599,t=-8.310,-5.731,-5.439,all P=0.000). P0.1 max and P0.1/MV in the CI group were lower than those in the healthy control group;the P0.1 did not have significant difference in these two group; the P0.1/P0.1max and P0.1/Plmax in the CI group were significantly higher than those in the healthy control group; the PImax was correlated with PO2, O2sat, P(A-a) O2, P0.1max, P0.1, P0.1,/PImax, P0.1/P0.1max, FVC, FEV1.0 and PEF; the PEmax was correlated with P0.1/ PImax, FVC, FEV1.0 and PEF. Conclusion The respiratory function of patients with CI has been impaired, the oxygenated index is cut down and the respiratory drive and respiratory drive store are decreased.

Results The discriminating power of the integral and mostly integral thyroid cartilags was 100 % , while the incomplete thyroid cartilages 90 % . Conclusion This method can be used for sex discrimination of the thyroid cartilage in adult Chinese Han population.

Objectives To investigate the process and the result of the repair of the sciatic nerve in rat by chitosan tube and polyglycolic fiber Methods The left sciatic nerves of rats were transected with 10 mm gap, then repaired with the nerve grafts in combination of NRF Walking track analysis, immunohistochemical and transmission electron microscopic examinations were carried out at different time after the operation Results Fibrous membrane and capillary could be observed on the surface of the grafts at the first week after the operation; at the 4th week, the regenerated nerve fibers grew more than half of the distances of the gap; at the 8th week, regenerated nerve fibers overcame the gap, many myelinated nerve fibers and thick myelin sheathes could be observed; at the 16th week, the grafts almost degraded and were substituted by the regenerated nerve Walking track analysis showed that sciatic nerve function recovery appeared at the 8th week, and that at the 16th week, approximately 60% of the sciatic nerve function was recovered Conclusion The nerve graft with NRF can stimulate the growth of vessels and the formation of the fibrous membrane, and is useful to the migration of Schwann cells and regeneration of axons, and degrade after the nerve regeneration

Objective To compare the analgesia and side-effects of different concentrations of sufentanil combined with 0.125% ropivacaine for postoperative epidural analgesia after general thoracic surgery.Methods Thirty-six ASA Ⅰ-Ⅲ patients (25 males, 11 females) ages 21-64 yrs weighing 42-79 kg undergoing elective general thoracic surgery under general anesthesia were randomly assigned to receive patient-controlled epidural analgesia (PCEA) with 0.125% ropivacaine combined with sufentanil 0.4 (group A, n = 12) , 0.5 (group B, n = 12) or 0.6 ?g?ml-1 (group C, n = 12) . Epidural catheter was placed at T7,8 or T8,9 interspace. The PCEA pump was set up with back ground infusion of 2 ml?h-1 , a3ml bolus dose and a 30-min lock-out period. VAS scores was used to assess analgesia at rest and during movement. The total bolus doses, PCEA button pressing times (effective/actual), vital signs including MAP, HR, respiratory rate, SpO2 and side effects (nausea, vomiting, pruritus and dyspnea) were recorded. Results During the 48 hours after operation the VAS scores in group C were significantly lower than those in group A and B ( P

Objective To analyze the variation in CTL epitope of hepatitis B virus (HBV) popular in China. Methods Amino acid sequences of 13 cytotoxic T lymphocyte (CTL) epitopes previously reported abroad were taken as reference sequences, and comparison was made draw between these reference sequences and both the 45 CTL-epitopic sequences obtained from the Genbank and also 5 CTL-epitopic sequences from native patients with chronic hepatitis B, using Vector NTI software. Results Sequence variations were observed frequently within several CTL eptitopes of HBV genotype B and C compared with the reference sequences. In the 13 analyzed CTL epitopes, 4 showed variation accounting over 70% in genotype B, and 2 have variance over 70% in occurrence in genotype C. Among these, C18-27 (FLPSDFFPSV), HBcAg-derived CTL epitope which was the most frequently studied previously, is showed in variation more frequently in HBV genotype B and C popular in China, reaching 71% and 97%, respectively. Conlusion Some CTL epitopic sequences of HBV genotype B and C popular in China have their own charactiristic difference from previously reported ones, which should be considered in the study of CTL response of Chinese subjects.
