Objective:To evaluate the influence of prophylactic intra-coronary injection nitroglycerin with diltiazem in patients of acute ST segment elevation myocardial infarction(STEMI) Methods:This study was conducted in 212 patients with acute STEMI who underwent primary percutaneous coronary inter- vention(PCI)in our center from January 2001 to December 2006.The patients were randomly assigned to receive intra-coronary nitroglycerin with dihiazem(n = 87)or none of them(125)before intervention.The clinical data,coronary angiography data after intervention,ST-segment resolution,area under the curve of CK-MB,ejection fraction(EF)and left ventricular end-diastolic di- mension several days alter operation and the major adverse cardiac events(MACE)were analyzed systemically. Results:Ten(11.5%)patients in study group and 28(22.4%)in control group had MACE(P = 0.042).The difference of re-hospitalization was also significant(19.5% vs 37.6%,P = 0.008).No/slow reflow occurred less in study group than in con- trol group,but the difference was not significant.Corrected TIMI frame count was lower(34.4?11.3 vs 38.9?17.2,P = 0.034) and myocardial blush grade was higher(2.65?0.6 vs 2.41?0.7,P =0.018)in study group.ST-segment resolution,area under the curve of CK-MB in 5 days after operation,EF and left ventricular end-diastolic dimension in study group were more significant than those in control group(P

ObjectiveTo investigate the effects of acupuncture on the serum leptin and IGF-1 in patients with post-stroke depression (PSD).MethodsBy using Hamilton rating scale for depression (HAMD),94 patients with PSD were recruited and randomly divided into 2 groups:acupuncture group and control group.All patients were given routine clinical treatments and second level medical prevention.Patients in the acupuncture group received Linggui Ba fa acupuncture treatment and oral administration of Sertraline and patients in the control group were treated with oral administration of Sertraline only.Serum levels of letpin and insulin growth factor (IGF-1) were measured by enzyme linked immunosorbent assay (ELISA) before and after treatments in all patients.ResultsThe levels of leptin and IGF-1 in patients of acupuncture group were significantly lower than that of the control group after treatment[(17.06 ± 12.38) ng/ml vs (32.27 ± 15.09)ng/ml,P<0.01; (52.61±24.74)ng/ml vs (77.15±20.83)ng/ml,P<0.01 respectively].The scores of HAMD in acupuncture group were significantly lower than that of control group after the treatment[(8.06±3.32)、(13.67±8.05)]and 6 month later[(6.52±2.08)、(10.26±6.16)].ConclusionThe serum levels ofleptin and IGF-1 were significantly lower and depression symptoms were improved after acupuncture in elderly patients with post-strok depressin.

The study aimed to establish a population pharmacokinetic/pharmacodynamic (PPK/PD) model of warfarin. PCR-RFLP technique was used to genotype the CYP2C9 and VKORC1 polymorphisms of 73 patients. RP-HPLC-UV method was used to determine the 190 plasma concentrations of warfarin. Application of NONMEM, the clinical information and 263 international normalized ratio (INR) monitoring data were used to investigate the effect of genetic, physiological, pathological factors, other medication on clearance and anticoagulant response. The final model of warfarin PPK/PD was described as follows: CL = θCL · (WT/60)θWT · θCYP · eηCL (if CYP2C9*1/*1, θCYP = 1; if *1/*3, θCYP = 0.708); EC50 = θEC50 · θVKOR · eηEC50 (if VKORC1- 1639AA, θVKOR = 1; if GA, θVKOR = 2.01; V = θV; K(E0) = θK(E0); Emax = θEmax; E0 = θE0 · eηE0. Among them, the body weight (WT), CYP2C9 and VKORC1 genotype had conspicuous effect on warfarin PK/PD parameters. The goodness diagnosis, Bootstrap, NPDE verification showed that the final model was stable, effective and predictable. It may provide a reference for opitimizing the dose regimen of warfarin.

Objective To investigate the relationship between the expression of MMP-7 in peripher- al blood and esophageal cancer.Methods By using Real time RT-PCR, blood samples from 82 cases with postoperative esophageal cancer were detected.Results 37.8 %(32/82)patients were positive for MMP-7 mRNA expression.MMP-7 mRNA positivity significantly correlated with lymph node metastasis,stage,and hematogeneous metastasis.Recurrent disease was found in 28 of 82 cases. Of 28 patients experiencing re- lapse,15 patients were serially follow-up in every three months.The number positive of MMP-7 mRNA be- fore detection by imaging,at the same time of detection by imaging,and after detection by imaging was 5 cas- es,8 cases and 2 cases respectively.Conclusion Examination of MMP-7 mRNA in peripheral blood during follow-up is useful for early detection of occult recurrence.

Objective To analyze the clinical characteristics of juvenile myelomonocytic leukemia(JMML) and the PCNA levels of the hyperoxia -exposure group (6 h)decreased,and the difference in PCNA protein expres-sion levels was significant of gene diagnose for JMML.Methods Clinical data were retrospectively analyzed in 21 pa-tients suffering from JMML based on new 2009 World Health Organization diagnostic criteria from January 201 3 to June 201 4 in Beijing Children′s Hospital,Capital Medical University.Results There were 85.7% (1 8 /21 cases)patients within 4 -year -old children,and the median age was 23 months (2 -86 months).Fever and abdominal symptoms were the prominent clinical symptoms,52.4% (1 1 /21 cases)with fever,38.1 % (8 /21 cases)with abdominal dis-tention,diarrhea and other abdominal symptoms,80.5% (1 9 /21 cases)had splenomegaly (mild 1 9.1 %,middle 33.3%,severe 38.1 %),and some patients had other tissue infiltration,such as rash,yellow tumor and lymphnode enlargement.Peripheral blood cell count showed that the white blood cells increased because of anemia or thrombocyto-penia,ranging from 1 0.40 ×1 09 /L to 82.1 4 ×1 09 /L(median,26.1 0 ×1 09 /L),and the monocyte counts ranged from 1 .46 ×1 09 /L to 21 .60 ×1 09 /L(median,3.79 ×1 09 /L),characteristics of JMML gene abnormality was detected in 1 7 cases:including 1 1 single gene mutation,and 6 cases with double gene mutations.PTPN11 was the highest frequency of occurrence,accounting for 52.9% (9 /1 7 cases),and NF1 mutation was 35.3% (6 /1 7 cases).All the patients were followed up by phone call,the median follow -up time was 371 days (57 -562 days),6 patients were lost to follow -up,7 patients died,2 patients were alive after hematopoietic stem cell transplantation,1 patient converted to acute non lymphocytic leukemia,and 5 patients were still alive after receiving symptomatic treatment.Among dead cases,PTNT11 gene mutation and NF1 gene mutation were detected in 6 patients;among living children after hematopoietic stem cell transplantation,RAS and PTNT11 mutations were detected in 2 patients;among living children after symptomatic treat-ment,RAS mutation was detected in 2 patients and PTPN11 +CBL mutation in 1 case.Conclusions The symptom and laboratory examination of JMML have no specificistics,with poor prognosis,gene diagnose has guiding significance for JMML diagnose and for selecting therapy.

OBJECTIVETo evaluate the affection of crushing technology on quality. The dissolution of Pills of Six Herbs with Rehmunnia prepared by different crushing technology was determined by taking the dissolution of Paeonol as test marker.
METHODThe Pills was prepared with the fine powder which was crushed by normal crusher or super fine crusher. The rotatory-basket method was used, and the cumulative dissolution percentage was determined by UV.
RESULTStatistics indicated there was a significant difference in dissolution parameter (T50) between super fine crushing powder Pills and normal fine-crushing powder Pills (P < 0.01), and there was a difference in dissolution of different batches of Pills of Six Herbs with Rehmunnia prepared by the normal crush technique (P < 0.05).
CONCLUSIONThe determination of dissolution of Pills of Six Herbs with Rehmunnia is necessary. In order to improve the quality of drugs, we should adopt the technique of super fine crushing in the preparation procedure.
