1.Progress of nuclear transcription factor Sp1 regulating angiogensis of tumor
Journal of International Oncology 2012;39(1):18-21
Sp1 is one of the nuclear transcription factors which are widely expressed in human body.It plays an important role in human growth and physiological activities,and is highly expressed in many kinds of tumors'tissue.Sp1 participates in regulating growth,invasion,angiogensis actions of tumor by regulating downstream gene(s) transcription.Some grow factors and tumor suppressor genes can regulate the expression of VEGF by Sp1,and then participate in angiogensis of tumor by two main mechanisms:kinases inducing Sp1 phosphorylation and the interact of Sp1 and other proteins.

Objective To observe the preventive effect of dexmedetomidine on penile erection(PE) after general anesthesia induction and urinary bladder irritation during recovery(UBIR) with urethral catheterization in male patients.Methods A total of 1000 male patients with ASA grade Ⅰ ~ Ⅱ were randomly divided into control group(group C) and dexmedetomidine group (group D,n =500).Dexmedetomidine (1 μg/kg) was intravenous pumped in group D and saline was given in group C 15 minutes before anesthesia induction.Both groups started catheterization within 10 minutes after endotracheal intubation.The incidence and grade of PE before infusion(To),before induction(T1),before catheterization(T2) and during catheterization (T3) were observed.The degree and extent of UBIR were observed and recorded.Results The incidence and grade of PE at T3 time-point in group C were highest (Compared with T2 and other time-points,P < 0.05),but there was no statistically differences in incidence and grade of PE in group D between at T3 and T2time points (P > 0.05).The incidence of PE at T2 and T3 time-points were 4.0% and 5.6% in group D,which was significantly lower than those in group C (15.4%,77.8%,P<0.05).The incidence of PE at grade 1,2 and3 was 4.4%,1.0% and0.2% respectively in group D,which was significantly lower than those in group C (62.6%,11.4%,3.8%,P < 0.05).The incidence of UBIR was significantly lower (28.4% vs 63.0%,P < 0.05),among which the incidence of UBIR at grade 1,2 and 3 were 15.6%,10.4% and 2.4%,which was significantly lower in group D than those in group C (22.0%,21.0%,20.0%,P < 0.05).Conclusion 1μg/kg dexmedetomidine pumped before anesthesia induction could prevent the occurrence of PE during catheterization and UBIR,which can improve patients' comfort.

Autophagy is a crucial biological process in eukaryotes, which is involved in cell growth, survival and energy metabolism. It has been confirmed that autophagy mediates toxicity of anticancer drugs, especially in heart, liver and neuron. It is important to understand the function and mechanism of autophagy in anticancer drugs-induced toxicity. Given that autophagy is a double-edged sword in the maintenance of the function of heart, liver and neuron, the autophagy-mediated toxicity are very complicated in the body. We provide a review on the concept of autophagy and current status about autophagy-mediated toxicity of anticancer drugs. The knowledge is crucial in the basic study of anticancer drugs-induced toxicity, and provides some strategies for the development of alleviating the toxicity of anticancer drugs.

Objective To evaluate anesthesia efficacy of sevoflurane combined midazolam and remifentanil and propofol in patients undergoing short surgery. Methods Fifty ASA Ⅰ or Ⅱ patients who scheduled for elective surgery under general anesthesia were enrolled in study. The anesthesia was induced with intravenous injection of midazolam 0.03 mg/kg and sevoflurane inhalation. Induction of anesthesia was started with 6% sevoflurane and fresh gas flow rate of 6 L/min. The inspired concentration of sevoflurane was reduced to 2% as soon as eyelash reflexes of these patients were abolished. At the same time, remifentanil 2 μg/kg was injected slowly over 1 min,and 30 s later,patients were mechanically ventilated after tracheal intubation. 2% sevoflurane was kept inhaling, and remifentanil and propofol were kept pumping for anesthesia maintenance. The mean arterial pressure (MAP), heart rate, pulse oxygen saturation (SpO_2) and bispectral index (BIS)were recorded before administration,at the time of the disappearance of eyelash reflex, immediately before tracheal intubation,and immediately after tracheal intubation. The time period from sevoflurane inhalation to the disappearance of eyelash reflex was also recorded. And conscious recovery, spontaneous breathing recovery,the endotracheal extubafion time and OAAS score were recorded. Results All patients were successfully intubated at the first attempt. The satisfactory intubation conditions were found in 82% (41/50) of cases. The time period from sevoflurane inhalation to the disappearance of eyelash reflex was (73 ± 12) s. MAP,heart rate and SpO_2 remained stable and BIS was maintained at 45-55 before and after tracheal intubation, and all patients were quick recovery. Conclusion The anesthesia efficacy of sevoflurane combined midazolam and remifentanil and propofol without muscle relaxant in patients undergoing short surgery is smooth, safe and reliable.

ObjectiveTo define the difference of urine analysis result,α1-microglobulin (α1-MG) and β2-microglobulin ( β2-MG) between those patients suffering from calcium oxalate stone,non-calcium oxalate stone and non-urolithiasis controls at the same time period.MethodsData from 100 patients admitted to the Department of Urology,First Affiliated Hospital of Anhui Medical University from July,2010 to September,2010 were reviewed.66 patients (45 men,21 women) suffered from urolithiasis,and 34 patients (22 men,12 women) were non-urolithiasis.Patients' ages in urolithiasis group varied from 13 to 78 years and the male to female ratio was 2.1∶1.0.The patients in non-urolithiasis controlgroup aged from 12 to 80 years and the male to female ratio was 1.8∶1.0.Blood and urine were taken from the patient the next morning after admission.The biochemistry from blood and 24 h urine were measured by automatic biochemistry analyzer.The α 1-MG and β2-MG content were measured by radioimmunoassay.The stone compositions were analyzed by infrared spectroscopy.ResultsThere was difference in the levels of serum creatinine and blood urea nitrogen among three groups ( P < 0.05).In controls,those with calcium oxalate stone had higher level of urinary α1-MG and β2-MG,but there were no differences in the urinary electrolyte levels.Group of non-calcium oxalate stones urinary uric acid levels were higher than calcium oxalate and control groups,the difference was statistically significant.ConclusionsIn the formation of uric acid stones,uric acid increased as independent risk factors.α1-MG,β2-MG may promote the formation of calcium oxalate stones.

Objective To investigate the diagnostic value of hyperenhancement sign on ultrasound,CT and their combination in diagnosis of thyroid benign and malignant nodules.Methods The contrast-enhanced ultrasound and enhanced CT datas of 172 thyroid nodules in 144 cases confirmed by operation and pathology were retrospectively analyzed,including 97 benign nodules and 75 malignant nodules.According to the degree of enhancement,these nodules were divided into iso-or low-enhancement and hyperenhancement.The distributions of ultrasound hyperenhancement,CT hyperenhancement and both of them in thyroid benign and malignant nodules,adenomatoid lesions and nodular goiters were analyzed,followed byx2 test for statistical analysis.Results In 172 thyroid nodules,the proportions of ultrasound hyperenhancement,CT hyperenhancement and both of them in thyroid benign and malignant nodules were 53.6%(52/97) and 20.0%(15/75)(x2=20.090,P<0.05),34.0% (33/97) and 4.0% (3/75) (x2=23.033,P<0.05),31.0% (30/97) and 0% (0/75) (x2=28.096,P<0.05),respectively.Their sensitivity and specificity of diagnosing benign nodules were 53.6% (52/97) and 80.0% (60/75),34.0% (33/97) and 96% (72/75),30.9% (30/97) and 100% (75/75),respectively.The proportions of ultrasound hyperenhancement,CT hyperenhancement and both of them in adenomatoid lesions and nodular goiters were 96.9%(31/32) and 32.3%(21/65)0x2=35.946,P<0.05),65.6%(21/32) and 18.5%(12/65)(x2=21.250,P<0.05),65.6%(21/32) and 13.8% (9/65)(x2=26.912,P<0.05).Their sensitivity and specificity of diagnosing adenomatoid lesions were 96.9%(31/32) and 67.7%(44/65),65.6%(21/32) and 81.5%(53/65),65.6%(21/32) and 87.2%(56/65).Conclusions Ultrasound hyperenhancement,CT hyperenhancement for diagnosing thyroid benign nodules are of significant value.Especially for adenomatoid nodules,ultrasound hyperenhancement has a higher sensitivity,while CT hyperenhancement has a higher specificity.Their combination can further improve the diagnostic specificity,thus reducing the unnecessary surgical trauma.
