Objective To analyze the clinical features of acute leukemia(AL) with positive mixed lineage leukemia(MLL)fusion gene in children,and explore their treatment protocols,prognosis factors,and so on.Methods Clinical features,treatment protocols,and prognosis factors were studied retrospectively among 51 AL patients with MLL fusion gene.MLL fusion gene was detected by morphology immunology,cytogenetics,molecul arbiology and reverse transcrption polymerase chain reaction(RT-PCR).Results Fifty-one AL patients with MLL fusion gene positive,included 37 cases of acute lymphoblastic leukemia(ALL) and 14 cases of acute myelocytic leukemia(AML).Forty-two patients exhibited abnormal clonal chromosome 11.MLL fusion gene rearrangements and MLL fusion gene partial tandem duplication were found among 36 cases and 15 cases,respectively.Thirty-two cases who received regular chemotherapy were followed up.Twenty-four cases including 19 cases of ALL and 5 cases of AML had achieved complete remission(CR).Six cases including 5 cases of ALL and 1 cases of AML had achieved more than 2 years CR.Sixteen cases were alive update including 12 cases of ALL and 4 cases of AML.Ten cases of positive MLL fusion gene were turning negative.Up to now,6 cases relapsed and 6 cases were dead.Conclusions The incidence of AL children with positive MLL fusion gene is low.It has some features,such as,high replapse rate and poor prognosis.A few patients sensitive to chemotherapies can achieve CR.They live with constant negative MLL fusion gene.

Objective To investigate the diagnostic value of non-invasive cardiac output parameters:cardiac index (CI) and minute distance (MD), in premature infants with patent ductus arteriosus (PDA) and determine the cut-off value. Methods Clinical data of 98 premature infants admitted to the neonatal intensive care unit from January 2015 to June 2015 were collected. These premature infants were divided into the treated PDA group (n=30),the untreated PDA group (n=28) and the normal premature group (n=40) based on the results of echocardiogram in the first three days after birth and the use of drugs. Non-invasive cardiac output parameters were measured in the first three days after birth. The data were analyzed by t test, analysis of variance and SNK-q test. The diagnostic value of CI and MD for PDA was analyzed by the receiver operating characteristic curve. Results By preliminary analysis of the ROC curve,CI and MD were the most representative parameters for the diagnosis of PDA which need to be treated clinically, we thus chose CI and MD in this study. The aortic and pulmonary arterial CI and MD in the treated PDA group were significantly higher than in the untreated PDA group and the normal premature group (all P<0.05). There were no significant differences between the untreated PDA group and the normal premature group in the aortic and pulmonary arterial CI and MD (all P>0.05). The cut-off value of the aortic CI and MD was 2.95 L/(min·m2) and 21.50 m/min, respectively, while that of the pulmonary arterial CI and MD was 4.55 L/(min·m2) and 26.50 m/min, respectively. The sensitivity and specificity of the combined aortic CI and MD for the treated PDA group were 0.90 and 0.82, and those of combined pulmonary arterial CI and MD were 0.87 and 0.82;and those of combined aortic and pulmonary arterial CI and MD were 0.80 and 0.88, respectively. Conclusions The non-invasive cardiac output parameters CI and MD have good diagnostic value for the PDA needing clinical treatment, and the combined use of the two parameters can improve specificity, and help formulate the early treatment strategy for premature infants with PDA. When aortic CI was ≥ 2.95 L/(min·m2) and MD was ≥ 21.50 m/min, a preliminary diagnosis of the PDA needing clinical treatment, can be made, and simultaneously when the pulmonary arterial CI was ≥4.55 L/(min·m2) and MD was≥26.50 m/min, the arterial duct should be closed timely.

To research the structure-activity relationship (SAR) of glycinamide-bearing compounds that used as inhibitors of dipeptidyl peptidase IV (DPP-IV), P32/98 and compound A were chosen as the leading compounds, heterocycles containing nitrogen atom were introduced to form amide, and different residues on a-position of carbonyl were designed. The nineteen designed compounds were synthesized by a simple route and were evaluated as inhibitors of DPP-IV. All of the structures were characterized by 1H NMR and HRMS. The preliminary SAR result was obtained.

OBJECTIVETo observe the effect of Shenshuaining Granule (SG) combined telmisartan on serum creatinine (SCr) levels and urinary albumin contents in diabetic nephropathy (DN) patients, and to explore its efficacy.

METHODSTotally 204 DN patients were recruited, and further assigned to 3 groups, i.e., the early DN group, the clinical stage of DN with normal renal function group, the clinical stage of DN with insufficient renal function group. Patients in the same group were randomly allocated to the telmisartan treatment group, the SG treatment group, and the combination of SG and telmisartan treatment group, 68 in each group. Patients in the telmisartan treatment group took telmisartan tablet, 80 mg per day, once daily. Those in the SG treatment group took SG, 5 g each time, 3 times per day. Those in the combination of SG and telmisartan treatment group took telmisartan tablet (80 mg per day, once daily) and SG (5 g each time, 3 times per day). The therapeutic course for all was 3 successive months. SCr levels, serum urea nitrogen (BUN),24 h urine microalbumin (24 h U-MA) were detected before and after treatment. Results In three different treatment groups, 24 h U-MA decreased after treatment in the telmisartan treatment group; SCr and BUN decreased after treatment in the SG treatment group; and 24 h U-MA, SCr and BUN decreased after treatment in the combination of SG and telmisartan treatment group (P<0.05). In the clinical stage of DN with insufficient renal function group, SCr obviously increased after treatment in the telmisartan treatment group (P <0. 05). In the 3 DN stages, SCr and 24 h U-MA obviously decreased in the combination of SG and telmisartan treatment group, when compared with the telmisartan treatment group and the SG treatment group (P<0.05). Compared with the telmisartan treatment group, SCr and BUN obviously decreased in the SG treatment group, but 24 h U-MA quantitation obviously increased (P<0.05). BUN obviously decreased in the combination of SG and telmisartan treatment group (P<0. 05).

CONCLUSIONThe combination of SG and telmisartan could decrease urinary albumin, and stabilize SCr levels.

To study the effect of steaming and baking process on contents of alkaloids in Aconite Lateralis Radix (Fuzi), 13 alkaloids were analyzed by UPLC-MS/MS equipped with ESI ion source in MRM mode. In steaming process, the contents of diester-diterpenoid alkaloids decreased rapidly, the contents of monoester-diterpenoid alkaloids firstly increased, reached the peak at 40 min, and then deceased gradually. The contents of aconine alkaloids (mesaconine, aconine and hypaconine) increased all the time during processing, while the contents of fuziline, songorine, karacoline, salsolionl were stable or slightly decreased. In baking process, dynamic variations of alkaloids were different from that in the steaming process. Diester-diterpenoid alkaloids were degraded slightly slower than in steaming process. Monoester-diterpenoid alkaloids, aconine alkaloids and the total alkaloids had been destroyed at different degrees, their contents were significantly lower than the ones in steaming Fuzi at the same processing time. This experiment revealed the dynamic variations of alkaloids in the course of steaming and baking. Two processing methods which can both effectively remove the toxic ingredients and retain the active ingredients are simple and controllable, and are valuable for popularization and application.

OBJECTIVETo evaluate factors predictive of blood loss in radical cystectomy in a contemporary series.

METHODSFrom December 1996 to December 2008, clinical data of 233 patients who underwent radical cystectomy were reviewed retrospectively. Various preoperative and operative factors were assessed for their association with blood loss using univariate, multivariate regression and correlation analysis.

RESULTSOne hundred eighty-one patients underwent open radical cystectomy and 52 cases were treated by laparoscopic radical cystectomy. Overall mean operative time was (339 ± 84) minutes, and mean blood loss was (818 ± 756) ml. On univariate analysis, body mass index (F = 9.039), history of pelvic operation (t = -4.365), anesthetic techniques (t = 3.125), surgical type (t = 6.643), use of Ligasure (t = 6.923), and urethra resection (t = -1.984) correlated with blood loss. However, multiple linear regression showed that body mass index (R(2) = 0.256, P < 0.001), history of pelvic operation (R(2) = 0.222, P < 0.001), use of Ligasure (R(2) = 0.172, P < 0.001), and surgical type (R(2) = 0.271, P = 0.027) were significant predictors of blood loss. The transfusion was required in 176 of 233 patients (75.5%) with a median requirement of (649 ± 569) ml. Likewise logistical regression analysis revealed that older age (OR = 3.2, P = 0.010), female gender (OR = 33.7, P = 0.013), anemia (OR = 6.6, P = 0.039), increased blood loss (OR = 14.3, P < 0.001), open radical cystectomy (OR = 6.4, P = 0.036) and nonuse of Ligasure (OR = 10.1, P < 0.001) were predictors of transfusion need.

CONCLUSIONSIncreased body mass index, history of pelvic operation, open radical cystectomy, and non-use of Ligasure were independent predictors of increased blood loss during radical cystectomy. Such a prediction formula has an important role in identifying high risk patient for increased blood loss and transfusion need before radical cystectomy.
