Transforming growth factor-?(TGF-?) is a kind of multifunctional cytokine that regulates cell growth,differentiation,cellular senescence,apoptosis,wound healing and embryo development.As a tumor suppressor,deregulated or aberrant TGF-? signaling has been strongly implicated in human solid tumors,as well as in normal and malignant hematopoiesis.TGF? exerts an inhibitory role during the whole procedure of hematopoiesis.As a cell cycle inhibitor,it maintains cells in a quiescent state and can downregulate expression of hematopoiesis activators and oncoproteins.In malignant hematopoiesis,altered expression of coactivators or corepressors involve in TGF-?-induced transcriptional responses and loss/disruption of TGF-? target gene expression.Then malignant cells grow and differentiate abnormally.In acute promyelocytic leukemia,PML-RAR? may inhibit TGF-? signaling through inhibition of cPML and nPML.Degradation of PML-RAR? by ATRA restores this signaling pathway.

OBJECTIVETo observe the therapeutic effect and relevant mechanism of shuxuening Injection (SI) in treating patients with active ulcerative colitis (UC).

METHODSTotally 91 patients with active UC were randomly assigned to 2 groups, 44 in the control group and 47 in the treatment group. Patients in the control group received routine treatment, while patients in the treatment group additionally received intravenous injection of SI (15 mL), twice daily for 14 days in total. Colonoscopy was performed before and after treatment. The therapeutic effect was assessed by Mayo scoring system and the grading of activities evaluated by Baron endoscope. Serum levels of IL-6 and TNF-α were detected by ELISA. The activity of SOD was detected by xanthine oxidase method. The content of MDA was detected by thiobarbituricacid (TBA). Besides, 20 healthy subjects were recruited as the healthy control group.

RESULTSTotally 82 patients completed the study (40 in the control group and 42 in the treatment group). There was no statistical difference in serum levels of IL-6, TNF-α, SOD, MDA, the Mayo score and endoscope grading between the two groups before treatment (P >0. 05). Compared with the healthy control group, serum levels of IL-6, TNF-α, MDA significantly increased (P <0.01), and the serum SOD level decreased (P < 0. 05) in the treatment grup and the control group before treatment. Compared with before treatment in the same group, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased in the treatment group and the control group after treatment (P <0. 01, P <0. 05). Compared with the control group after treatment, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased (P <0.01, P <0.05), the serum SOD level increased (P <0.05) in the treatment group after treatment. The serum SOD level was obviously negative correlated with serum levels of IL-6, TNF-a, Mayo score, and endoscope score (r = -0. 621, -0.638, -0. 509, -0.787, P <0.01). The serum MDA level was obviously positive correlated with serum levels of IL-6, TNF-α, Mayo score, and endoscope score (r =0.711, 0. 882, 0. 525, 0. 639, P <0.01).

CONCLUSIONSI could improve inflammatory injury and clinical symptoms of patients with active UC, and its mechanism might be associated with antioxidant and scavenging oxygen free radicals.

Objective To investigate the effects of three laparoscopic bariatric operations on relieving type 2 diabetes in morbid obese patients. Methods From 2005 to 2009, 15 morbid obese patients with type 2 diabetes received bariatric operations in Shengjing Hospital including lapband operation (7 cases) , sleeve gastrectomy (7 cases) and gastric bypass(4 cases). All patients were followed up for more than 1 year. Results All patients recovered without major complications. Body weight decreased and BMI was respectively (27. 6 ± 2. 0) kg/m2, ( 26. 9 ± 1. 4) kg/m2 and (27. 5 ± 3. 0) kg/m21 year after operation. The excess BMI loss in three groups were (76. 4% ± 6. 8% ) , (83. 7% ± 4. 6% ), (85. 7% ±9. 5% ) 1 year after operation. On the other side, the fasting glucose levels and glycohemoglobin in gastric bypass group were much lower than that in other two groups. Conclusion All these operations were effective in controling the weights and fasting glucose levels, while the gastric bypass method is better than other two methods in weight and serum glucose control. Sleeve gastrectomy was better in weight and glucose control than lap band operation.

Objective To investigate the correlation between the plasma unconjugated bilirubin(UCB)and electrical activity of brain in term neonates with hyperbilirubinemia,and explore the parameters that possess the prognostic value and deduce a series of discriminant for prognostic judgment.Methods Thirty-two neonates with hyperbilirubinemia and 31 neonates without hyperbilirubinema(control group)were studied with standard EEG,and they were assessed for their neurological development in 3 and 6 months.A statistical method of Bayes Discriminant analysis was adopted to set up an equation with values of parameters of EEG,clinic datum and consequence.Stepdic and Dis-grim processes were used to pick out the parameters which had great significance for predicting the outcome of nervous system development.A series of discriminant was deduced for prognostic judgment and then cross validation was performed to assess the accuracy of the discriminant.Results 1.The standard EEG and brain electrical activity map records indicated that the hyperbilirubinemia group had longer maximum duration of interburst interval(IBI),longer mean duration of IBI,lower amplitude under all conditions,more anterior dysrhythmia(AD)in wake,and higher incidence of sleep-wake cycle disturbance.2.The plasma concentration of UCB was linear correlated with AD in wake.3.Gestational age,birth weight,plasma concentration of UCB,burst duration of IBI in trace alternate,amplitude in all sleep state,AD in wake,brief burst not in quiet sleep and sleep-wake cycle disturbance might play important roles in predicting the outcome of neonates with hyperbilirubinemia.Conclusions Cerebral electrical activity is an effective tool for predicting neurologic outcome of neonates with hyperbi-lirubinemia.Cerebral electrical activity and clinic data will provide a new method for accurately predicting neurological development and prognosis.

Objective To investigate the prognostic values of serum lactate dehydrogenase(LDH) and beta-2 microglobulin(?2-MG) levels in patients with acute myeloid leukemia(AML). Methods The associations of serum LDH and ?2-MG levels at diagnosis,remission and relapse with treatment and prognosis in 68 patients with AML were retrospectively analysed. Results There were no difference in LDH and ?2-MG between AML subtypes patients.The level of serum LDH and ?2-MG at diagnosis and relapse were much higher than those at remission.Patients with lower level of LDH and ?2-MG got higher CR rate and longer term overall survival and disease-free survival.Patients with higher level of both LDH and ?2-MG got lower CR rate,shorter term of overall survival and disease-free survival than those with higher level of LDH or ?2-MG or those with normal level of LDH and ?2-MG. Conclusion LDH and ?2-MG is a singificant prognostic indicator for AML.While combined LDH and ?2-MG are more definite for the treatment and diagnosis.

ObjectiveTo compare the efficacy and safety of intermittent patient-initiated single-dose antibiotic prophylaxis and continuous antibiotic prophylaxis for the prevention of recurrent urinary tract infection (UTI) in postmenopausal women. MethodsA randomized controlled clinical trial was conducted for the prevention of recurrent urinary tract infection. Single dose of antibiotic was given every night in continuous antibiotic prophylaxis group and every time after exposure to conditions predisposed to UTI in intermittent antibiotic prophylaxis group. The duration of prevention was 12 months in both groups. ResultsThe effective rates of intermittent antibiotic prophylaxis and continuous antibiotic prophylaxis were 71.0% and 81.8% respectively (P＞0.05). The incidence of gastrointestinal adverse reaction in intermittent antibiotic prophylaxis group was significantly lower than that in continuous antibiotic prophylaxis group (7.7% vs 28.6%,P＜0.05). ConclusionsCompared with continuous antibiotic prophylaxis, intermittent patient-initiated single-dose antibiotic prophylaxis is a better prophylaxis with less gastrointestinal adverse reactions for the prevention of recurrent urinary tract infection in postmenopausal women.

OBJECTIVETo study features of brain gray matter injury in cerebral infarction patients and intervention of scalp acupuncture by using voxel-based morphology.

METHODSA total of 16 cerebral infarction patients were recruited in this study, and assigned to the scalp acupuncture group and the control group, 8 in each group. Another 16 healthy volunteers were recruited as a normal group. All patients received scanning of T1 structure. Images were managed using VBM8 Software package. Difference of the gray matter structure was compared among the scalp acupuncture group, the control group, and the healthy volunteers.

RESULTSCompared with healthy volunteers, gray matter injury of cerebral infarction patients mainly occurred in 14 brain regions such as cingulate gyrus, precuneus, cuneus, anterior central gyrus, insular lobe, and so on. They were mainly distributed in affected side. Two weeks after treatment when compared with healthy volunteers, gray matter injury of cerebral infarction patients in the scalp acupuncture group still existed in 8 brain regions such as bilateral lingual gyrus, posterior cingulate gyrus, left cuneus, right precuneus, and so on. New gray matter injury occurred in lingual gyrus and posterior cingulate gyrus. Two weeks after treatment when compared with healthy volunteers, gray matter injury of cerebral infarction patients in the control group existed in 23 brain regions: bilateral anterior cingulum, caudate nucleus, cuneate lobe, insular lobe, inferior frontal gyrus, medial frontal gyrus, precuneus, paracentral lobule, superior temporal gyrus, middle temporal gyrus, lingual gyrus, right postcentral gyrus, posterior cingulate gyrus, precentral gyrus, middle frontal gyrus, and so on. New gray matter injury still existed in 9 cerebral regions such as lingual gyrus, posterior cingulate gyrus, postcentral gyrus, and so on.

CONCLUSIONSBrain gray matter structure is widely injured after cerebral infarction. Brain gray matter volume gradually decreased as time went by. Combined use of scalp acupuncture might inhibit the progression of gray matter injury more effectively.

It is the objective of this study to develop dynamic predictive model for the extraction process of red Ginseng using NIR spectroscopy. NIR spectroscopy was collected online and PLSR models were developed for total quantity of ginsenosides. The performance of NIR prediction model achieved R, RMSEC, RMSEP of 0.996 09, 0.018 9, 0.016 8, respectively. A first order dynamic mass transfer model was combined with NIR prediction of the quality indicator to predict the trajectory of the extraction process based upon the initial 3 or 4 data points. The results showed good agreement with actual measurements indicating reasonable accuracy of the predictive model. It could potentially be used for advanced predictive control of the extraction process.
