Objective To explore the effects of proteasome inhibitor bortezomib alone and in combination with chemotherapeutic agents in acute leukemia cell line HEL. Methods Tumor cell growth inhibition and apoptosis was measured by MTT assay and FACS analysis, respectively. Apoptosis- and cell cycle-associatd protein expression levels were measured by Western blotting assay. Results Bortezomib induced the suppression of tumor cell growth and apoptosis in a dose-dependent manner with an inhibitor concentration IC50 values 7.15 nmol/L in acute leukemia cell line HEL. Further combination treatment with doxorubicin or cytarabine increased tumor cell growth suppression in acute leukemia cell line, as compared to single drug treatment alone. Bortezomib caused an increase in G2/M in a time-dependent manner. Bortezomib alone and in combination with chemotherapeutic agents treatment increased the bax and p27 expression and decreased the bcl-2 expression even without influencing p53 expression levels. Conclusion Bortezomib may be an effective therapeutic drug for patients with acute leukemia. Combining bortezomib with doxorubicin might be more effective for displaying tumor cell growth inhibitor effects in acute leukemia cells through regulation of bcl-2, bax and p27 proteins and independent of p53 status.

Objective To investigate the effect of 12-lipoxygenase (12-LO) on the angiotensinⅡtype 1 receptor(ATlR) expression in mesangial cells (MC).Methods p38 MAPK activation and ECM protein expression were determined using AngⅡ-stimulated MC derived from normal and 12-LO knockout mice.AT1R expression was determined using 12-LO product 12(S)- HETE-stimulated MC,MC transfected with 12-LO gene and microdissected glomeruli derived from 12-LO knockout mice.RT-PCR and Western blot were used for evaluating mRNA and protein expression respectively.Results AngⅡstimulation increased p38 MAPK activation and ECM protein expression in normal MC,but not in MC derived from 12-LO knockout mice.Time-dependent and dose-dependent experiment showed that 12 (S)- HETE increased AT1R protein' expression in MC. Similarly,12 (S)-HETE increased AT1R mRNA expression in MC compared with control MC (P＜0.01). Furthermore,AT1R expression was lower in glomeruli derived from 12-LO knockout mice relative to genetic controls (P＜0.01) and MC stably overexpressing 12-LO had greater AT1R protein and mRNA expression relative to control MC (P＜0.01).Conclusion 12-LO activation can upregulate ATIR expression in MC.

Objective To document the MRI features of renal angiomyolipoma (RAML) containing minimal fat and to explore whether the MR features vary depending on the tumor size. Methods The MR findings of 15 cases of pathologically-proved RAML containing minimal fat were reviewed retrospectively from January 2008 to March 2010. All patients underwent MR in a 1.5 T or 3.0 T scanners. The MR features of the lesions were analyzed, with emphasis on the signal intensity and homogeneity on T2WI, in regards to pseudocapsule, lipid component, hemorrhage, cystic degeneration or necrosis, blood vessels, interface with renal parenchyma and enhancement pattern. All lesions were categorized into 2 groups; those with diameter ＞4 cm and those with diameter ≤4 cm. The difference of imaging characteristics between these two groups was analyzed using Fisher exact test. Results All 15 lesions demonstrated hypointensity on T2WI compared to the renal parenchyma. Homogeneous signal intensity on T2WI was seen in 6 lesions (6/15); peritumoral pseudocapsule in 3 lesions (3/15); cystic degeneration or necrosis, hemorrhage in 5 lesions (5/15); flow void of blood vessels in 2 lesions (2/15); lipid component in 4 lesions (4/15); angular interface with renal parenchyma in 10 lesions (10/15); homogeneous enhancement in 8 lesions (8/15). Fifteen lesions were divided into two groups; 9 categorized into group 1 (the maximum diameter ≤ 4 cm) and 6 into group 2 ( the maximum diameter ＞ 4 cm). Cystic degeneration or necrosis was seen in 0 of 9 in group one and 5 of 6 in group two respectively, hemorrhage(0 of 9 and 5 of 6 respectively) and pseudocapsule(0 of 9 and 3 of 6 respectively. The difference between these findings in the two groups demonstrated statistical significance (P ＜ 0. 05). Conclusion The MR features of RAML containing miminal fat were hypointensity on T2 WI,angular interface with renal parenchyma and homogeneous contrast enhancement, however, these findings can vary depending on the tumor size.

Objective: To learn the characteristics of adolescent pregnancy in Wenzhou from 2015 to 2019, so as to provide basis for protecting adolescent physical and mental health. Methods: Data of demographic characteristics, pregnancy and delivery outcomes of the women aged under 19 years ( adolescent pregnant ) and 20 to 34 years ( right-age pregnant ) who delivered in Wenzhou from 2015 to 2019 were collected from Wenzhou Maternal and Child Health Information Management System. The incidence of pregnancy complication, comorbidity and adverse delivery outcomes of adolescent pregnant women was compared with that of right-age pregnant women. Results: Among 536 753 parturients reported in Wenzhou from 2015 to 2019, there were 22 419 ( 4.18% ) of adolescent pregnancy and 430 163 ( 80.14% ) of right-age pregnancy. The average age of adolescent pregnant women was (18.11±0.82) years ( range, 10-19 years ). The majority of adolescent pregnant women were migrant population (19 437 cases, 86.70%), had an education level of junior high school and below ( 18 594 cases, 82.94% ), and had no occupation (19 192 cases, 85.61%). The incidence rates of anemia, gestational diabetes, postpartum hemorrhage, perineal laceration and premature delivery in adolescent pregnant women increased from 2015 to 2019 ( all P<0.05 ). The incidence rates of gestational diabetes, anemia, gestational hypertension, placental abruption, postpartum hemorrhage, perineal laceration, premature delivery, low birth weight, fetal death and stillbirth were 1.65%, 11.76%, 0.19%, 0.26%, 3.19%, 24.52%, 6.03%, 5.53%, 0.50% and 0.04% in adolescent pregnant women, which were significant different from 5.49%, 8.94%, 0.13%, 0.01%, 0.17%, 23.46%, 4.66%, 3.08%, 0.26% and 0.01% in the right-age pregnant women, respectively ( all P<0.05 ). Conclusions The adolescent pregnant population in Wenzhou are mainly migrant population with lower education level and no occupation. The incidence rates of pregnancy complication, comorbidity and adverse birth outcomes in adolescent pregnant population are higher than those in right-age pregnant population, and are increasing year by year.

Objective To investigate the association between chronic kidney dysfunction and the complexity of coronary artery disease in elderly patients.Methods A prospective study was conducted on 1380 consecutive patients underwent coronary angiography for the first time in our hospital and with angiographically diagnosed coronary artery disease from January 2011 to June 2012.The complexity of coronary artery disease were classified according to the American College of Cardiology/American Heart Association (ACC/AHA) grading system as types A,B1,B2,and C.Estimated glomerular filtration rate (eGFR) was calculated by the simplified Modification of Diet in Renal Disease(MDRD)equation.Patients were classified into 3 stages according to eGFR as follows:normal renalfunction(n=234,eGFR≥90 ml· min-1 · 1.73 m-2),mild renaldysfunction(n=881,60≤eGFR＜90 ml · min-1 · 1.73 m-2,and moderate or severe renaldysfunction(n=265,eGFR＜60ml · min-1 · 1.73 m-2).Ordinal logistic regression was used to analyze the association between chronic kidney dysfunction and the complexity of coronary artery disease.Results Patients with mild,moderate or severe renal dysfunction were older (F=56.82,P＜0.001),more predominantly female (x2 =66.29,P＜ 0.001) and more likely to have history of hypertension (x2 =17.57,P ＜ 0.001),diabetes (x2=20.97,P＜0.001) and hyperlipidemia (x2=10.48,P 0.005) than those with normal renal function.The percentage of lesions of types B2 or C in moderate or severe renal dysfunction group was higher than that in normal renal function group (x2=175.03,P＜0.001).The ordinal logistic regression showed that age,male,hypertension,diabetes,C-reactive protein and eGFR were independent risk factors for the ACC/AHA lesion classification.Conclusions Age,male,hypertension,diabetes,C-reactive protein and eGFR are independent risk factors for the complexity of coronary artery disease.

Objective To investigate the effects of total flavonoids in Gingko Biloba on glucose and lipid metabolism and liver function in rats with insulin resistance. Methods Forty SD rats were randomly divided into normal control group,model group,total flavonoids in Gingko Biloba group and rosiglitazone group(positive drug control group)(n=10).Models of insulin resistance were established by high glucose and high fat diet in model group,total flavonoids in Gingko Biloba group and rosiglitazone group.After treatment for 12 weeks,serum glucose,serum lipids,and parameters of insulin resistance,liver function and anti-oxidation capability were detected in each group,and histologic observations of liver tissues were conducted with adipose staining. Results The serum glucose,insulin resistance index(HOMA-IR),insulin action index(IAI),serum total cholesterol(TC),triglyceride(TG),liver malondialdehyde(MDA) and serum transaminase activity in total flavonoids in Gingko Biloba group were significantly lower than those in model group(P

Objective To investigate the clinical value of ~(99)Tc~m-ethylenedicysteine (EC) diuretic renography (DR) in pre-and post-operative pediatric congenital hydronephrosis.Methods The DR with injection of Furosemide at 15 min of forty children with hydronephrosis was retrospectively studied.The preoperative renal blood perfusion rate (BPR),effective renal plasma flow (ERPF),grade of hydronephrosis,renogram and renal dynamic imaging of pre- and post-operative kidneys were compared.The t-test and Mann-Whitney test were used for data analysis.Results (1) Of 40 pathological kidneys,the BPR increased 5.99% (t=-5.13,P＜0.01)from pre-operative to post-operative:(34.05±11.07)% to (40.04±8.56)%.The ERPF increased 12.48 ml/min(t=-4.35,P＜0.01) from pre-operative to post-operative:(57.81±34.32)ml/min to(70.29±5.37)ml/min.(2)The grade of hydronephrosis of 40 pathological kidneys improved significantly(Z=-2.64,P＜0.01) with the mean sum of ranks of 47.21 pre-operatively to 33.79 post-operatively.(3) As the hydronephrosis worsened,the collecting system became bigger,the renal parenchyma became thinner,the extent of intrarenal parenchymal photopenia became larger and the response to diuretic challenge in pathological kidneys decreased or became totally irresponsive.(4)Thirty-seven cases of obstruction at ureteropelvic junction (UPJO) and 3 cases at ureterovesical junction (UVJO) were diagnosed by DR,which were all confirmed by surgery.Conclusions DR is a reliable method to evaluate pediatric congenital hydronephrosis.It can accurately reflect the grade and (or) severity of the disease,guide therapy and assess the therapeutic success of operation.

ObjectiveTo clarify the influence of human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein 120 V4 region with mutations at amino acid locuses on its abilities to enter target cells.Methods Based on the facts that ADA strains was a CCR5-tropic strain,only had the ability to infect CCR5 cells; that HXB2 strains was a CXCR4-tropic strain,only had the ability to infect CXCR4 cells,serial glycoprotein 120 mutants with alanine substitution in V4 region of ADA and HXB2 strains,were constructed by overlaping PCR.Eukaryotic expression vectors of mutants and expression vectors of HIV framework gene with luciferase reporter gene were cotransfected into eukaryotic cells to produce pseudoviruse.Concentration of HIV-1 gag P24 in pseudoviruses was detected by enzyme-linked immunosorbent assay(ELISA).U87.CD4.CCR5 and U87.CD4.CXCR4 cells were infected with 20 and 40 ng pseudoviruses,with wild ADA and HXB2 strains as control groups,respectively.The ability to infect cells of pseudovirus of each mutant with HIV-1 V4- region mutated at amine acid locuses 386-417 was measured by detecting the luciferase activity (relative light unit,RLU).ResultsTen mutants with alanine substitution in V4 region of HIV-1 ADA and HXB2 strains were successfully constructed,respectively.Mutants of pseudoviruse with 20 ng and 40 ng at locuses 389-391 and 414-417 with alanine substitution of V4 region in both ADA and HXB2 strains lost completely the abilities to enter CCR5 and CXCR4 expressing cells[ (0 ± 0)％].It was found that introduction of alanine to ADAs 400-403 and ADAs 408-410 increased the ability to infect cells to (124 ± 35)％,(182 ± 29)％ and (127 ± 8)％,( 134 ± 16)％ with pseudoviruse of 20 ng and 40 ng,respectively.Likewise,the ability to infect CXCR4 expressing cells also increased to (144 ± 42 )％ and (121 ± 18 )％ with pseudoviruse of 20 ng and 40 ng,respectively by introduction of alanine to HXB2s 395-397.However,other mutants in V4 region of ADA and HXB2 only maintained partial entry abilities( 15％- 84％).ConclusionsMutants of V4 region of HIV-1 envelope glycoprotein 120 with alanine substitution at locuses 389-391 and 414-417 in both ADA and HXB2 strains have been constructed successfully.They completely lost the ability to enter target cells.
