AIM To establish an ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for the simultaneous content determination of gallic acid,matrine,danshensu,hydroxysafflor yellow A,caffeic acid,paeoniflorin,ferulic acid and cynaroside in Xuebijing Injection (Carthami Flos,Paeoniae Radix Rubra,Chuanxiong Rhizoma,etc.).METHODS The analysis of 5％ acetonitrile extract of this drug was performed on a 40 ℃ thermostatic ACQUITY UPLC(C) BEH C18 column (2.1 mm × 50 mm,1.8 μm),with the mobile phase comprising of acetonitrile-0.1％ formic acid flowing at 0.2 mL/min in a gradient elution manner,after which cluster analysis was applied to the determined contents.RESULTS Eight constituents showed good linear relationships within their own ranges (r ＞ 0.996 0),whose average recoveries were 95％-104％ with the RSDs of less than 3％.Generally the contents of various constituents in ten batches of samples were found to be stable except the certain differences contributed by gallic acid and paeoniflorin.CONCLUSION We should pay attention to the quality of different batches of Xuebijing Injection due to their uneven performance.

Objective To investigate the changes of serum cardiac troponin I(cTnI)and brain natriuretic peptide(BNP)in heart failure of children with pneumonia and their relationship with heart function.Methods Thirty healthy children aged from 5 months to 3 years old were randomly selected with 17 male and 13 female(healthy group).Thirty children with severe heart failure aged from 3 months to 2 years old were selected at the same time with 21 male and 9 female(heart failure group).Thirty children with ordinary pneumonia aged from 3 months to 3 years old were also sampled with 16 male and 14 female(ordinary pneumonia group).The peripheral bloods of 2-3 mL of all children were taken.The BNP level were measured by enzyme-linked immunosorbent assay and the cTnI level was determined by micro-particle enzyme immunoluminescent.Left ventricular ejection fraction(LVEF) and left ventricular fractional shor-tening(LVFS)were detected by echocardiography.SPSS 11.0 software was used to analyze the data.Results The levels of cTnI [(0.389?0.030) ?g/L] and BNP [(0.572?0.090) ?g/L] of heart failure group increased significantly compared with healthy and ordinary pneumonia group,while their LVEF and LVFS decreased significantly(Pa

Objective To compare and analyze the effect of prophylactic postoperative radiotherapy for esophageal carcinoma.Methods 102 such patients were treated with prophylactic radiotherapy after radical resection,to a total dose of 50-60 Gy.The extensive portal included supraclavicular region on both sides,entire mediastinum,the site of anastomosis and left gastric lymph node region in 43 patients.The re- gional portal range was different according to the different location of primary lesion in 59 patients.Results The 1-,3- and 5-year survival rate was 76%,51% and 43% respectively,with a median survival of 30 months.The 1-,3- and 5-year survival rate was 77%,52% and 41% in the extensive portal and 76%, 49% and 45% in the regional portal,respectively(P=0.884).According to multivariate analysis,N stage, number of metastatic lymph nodes and tumor length were independent prognostic factors.Conclusions Regional portal does not lower the survival rate when prophylactic postoperative radiotherapy is used in e- sophageal carcinoma.

Background and Objective: The role of adjuvant radiotherapy to the regional nodes in women with T1-T2 breast cancer and one to three positive nodes is controversial.This study compared and analyzed the prognosis of patients with T1-T2 breast cancer with one to three positive nodes after modified radical mastectomy with or without postoperative radiotherapy.Methods: The cases of 434 women patients with T1 to T2breast cancer with one to three positive lymph nodes after modified radical mastectomy were reviewed,of which 196 patients received postoperative radiotherapy and 238 patients did not.The ipsilateral chest wall and supraclavicular fossa were irradiated with doses of 46-50 Gy in 23-25fractions.Results: For all patients,the 3-and 5-year rates of overall survival(OS)were 94.7% and 85.7% respectively,local control(LC)96.5% and95.6% respectively,and disease-free survival(DFS)89.3% and 82.3%respectively.The 3-and 5-year OS rates for patients without radiotherapy were 92.7% and 97.1% and for those with radiotherapy were 82.4% and89.2%,both with significant differences(P=0.039).The 3-and 5-year LC rates for patients without radiotherapy were 94.8% and 98.4% and for those with radiotherapy were 93.6% and 97.7%,again with significant differences(P=0.041).The 3-and 5-year DFS rates for patients without radiotherapy were 87.8% and 91.3% and for patients with radiotherapy were 78.5% and86.1%(P=0.047).Conclusion: Postoperative radiotherapy confers better rates of OS,LC,and DFS in patients with T1-T2 breast cancer with one to three positive nodes after modified radical mastectomy.

Objective:To investigate the relationship between Creactive protein(CRP)/albumin ratio (CAR) and lymph node metastasis of gastric cancer. Methods:A total of 96 cases of gastric cancer were included in the study. The clinical pathological stage and lymph node detection in patients with gastric cancer were analyzed, with the preoperative CAR as the dependent variable. Results:1) The pa-tients with preoperative CAR>0.04 has higher transfer rate and metastasis than the patients with preoperative CAR≤0.04, and the dif-ference was significant (P<0.05). The lymph node stage of patients with preoperative CAR>0.04 was significantly higher than that of the patients with preoperative CAR≤0.04, and the difference was significant (P<0.05). 2) The mean CAR of patients with Borrmann typesⅠ,Ⅱ,Ⅲ, andⅣgradually increased;with the progression of the pathological stage of gastric cancer, the mean value of CAR in-creased. 3) During the operation, the total number of lymph node dissections was high and the mean value of CAR before the opera-tion was high. Conclusion:The correlation between preoperative CAR and lymph node metastasis in patients with gastric cancer may reflect the degree of lymph node metastasis to a certain extent.

Objective To define the maximum-tolerated dnse(MTD)and observe the side effect of escalating cisplatin with 5-fluorouracil in concurrent chemoradiotherapy for esophageal carcinoma in Chinese,with toxicity studied.Methods Previously untreated fifteen Chinese patients suffering from esophageal carcinoma received conventional fractionafiun radiotherapy,with 5 daily fractions of 2.0 Gy per week.The total radiation dose was 60 Gy.Concurrent chemotherapy dose escalation was given by the relatively safe and kidney-sparing modified Fibonacci sequence.The starting dose was cisplatin 37.5 mg/m~2 D1 and 5-fluorouracil 500 mg/m~2 D1-5, respectively.This regimen was repeated 4 times every 28 days.Escalation dose was eisplatin 7.5mg/m~2 and 5- fluorouracil 100mg/m~2.Every cohort contained at least 3 patients.If no dose-limiting toxicity(DLT)was observed, the next dose level was opened for entry.These courses were repeated until DLT appeared.MTD was declared as one dose level below which DLT appeared.Results DLT was defined as grade 3 radiation-induced esophngitis at the level of cisplatin 60 mg/m~2,5-fluorouracil 700 mg/m~2.MTD was defined as eisplafin 52.5 mg,/m~,5- fluorouracil 700 mg/m~2.The major side effect were radiation-induced esophagitis,leucopenia,nausea,vomiting and anorexia.Conclusion Maximun tolerated dose of cisplatin with 5-fluorouracil in concurrent chemoradiotherapy in the Chinese people with esophageal carcinoma were eisplatin 52.5 mg/m~2 D1,5-fluorouracil 700 mg/m~2 D1-5,repeated 4 times every 28 days.

Objective To evaluate the associations of oral contraceptives (OC) exposure,angiotensin-converting enzyme(ACE) gene polymorphism and their joint actions with the risk of stroke in Chinese women.Methods A case-control study,based on a set cohort,was carried out.Incident cases of stroke identified between July 1 1997 and June 30 2009 were enrolled.One hospital control and healthy community control were matched on region and age ( ± 3 years).A total of 453women with stroke and 919 controls were recruited.I/D genepolymorphism was detected by polymerase chain reaction (PCR) and amplification fragment length polymorphism (AFLP),A-240T polymorphism were detected by TagMan.Results ( 1 ) The risk of stroke gradually increased with the cumulative time of OC being used in women (P＜0.0001).Compared with non-users,the risk of stroke significantly increased among those with cumulative time of using OC longer than 20 years (adjusted OR was 2.07,with 95％ CI as 1.30-3.29).(2) ID/DD genotype of I/D locus indicated significantly an increased risk of hemorrhagic stroke (adjusted OR,2.37; 95％CI,1.46-3.84).(3)Women with ID/DD genotype of I/D locus or with TA/TT genotype of A-240T locus and using OC could significantly increase the risk of hemorrhagic stroke (adjusted OR was 4.59; with 95％ CI as 2.21-9.51 and OR was 2.50; with 95％CI as 1.42-4.38).(4) Data from multivariate analyses showed that both OC and ID/DD genotypes were important risk factors for hemorrhagic stroke.Conclusion ID/DD and TA/TT genotypes of ACE gene,OC and their joint action might increase the risk of stroke,especially on hemorrhagic stroke in Chinese women.

OBJECTIVETo study the expression levels of ERCC2, UDG, and PCNA in cisplatin-treated A549 cell line.

METHODComet assay, RT-PCR, and western blot were used to study the mRNA and protein expression levels of ERCC2, UDG, and PCNA.

RESULTSWhen treated with IC(20) cisplatin, the DNA damage level increased as the cisplatin treated time increased within 24 h of cisplatin treatment. The tail state 12 h and 24 h after treatment was 5.02 +/- 0.68 and 7.22 +/- 0.53 respectively, which was significantly higher than those of the controls (2.73 +/- 0.29). The tail state 24 h after treatment was not significantly different from that of the controls. The DNA damage level decreased to normal after cisplatin treatment in 24 h (tail state 3.64 +/- 0.7). The expression levels of ERCC2, UDG, PCNA protein (4.37 +/- 0.57, 5.47 +/- 0.46, 2.21 +/- 0.47 respectively) and mRNA (0.71 +/- 0.08, 0.74 +/- 0.06, 0.82 +/- 0.09) were increased significantly within 24 h exposure and decreased to normal 24 h after cisplatin treatment. The 3 enzymes' mRNA and protein expression increased when treated with cisplatin, but the changes of protein level were slower than those of mRNA levels.

CONCLUSIONSThe DNA repair capability in A549 cells increases after cisplatin treatment. Cisplatin was a positive regulation of ERCC2, UDG, PCNA expression levels, which causes the increase of mRNA, and protein. The positive regulation only works in a short time and returns normal after 24 h of cisplatin treatment.

Objective: To observe the clinical effect of Shengxue Mixture (SXM) in treating aplastic anemia and study the possible mechanism. Methods: Eighty-four patients in the treated group with Spleen-Kidney Yang deficiency syndrome and Spleen-Kidney Yin deficiency syndrome were treated with SXM-Ⅰ and SXM-Ⅱ respectively, and 30 patients in the control group were treated with Stanozolol. The clinical effect and several experimental parameters were also observed. Results: The basic cure was gained in 18 cases, remission in 23, markedly improved in 32, ineffective 11, total effective rate and cure remission rate of the treated group were 86.90% and 48.81% respectively, which were obviously better than those of the control group (P<0.05) with no obvious side-effect. While the patient's symptoms were alleviated, the peripheral blood cells increased, the ratio of T lymphocyte subsets tended to balance, the level of natural killer cell activity increased, interleukin-2 reduced, and reproduction of the bone marrow were markedly improved in most of the patients treated by SXM. Conclusions: SXM is an effective and safe drug for aplastic anemia. Its mechanism might be likely due to its regulating the immune function, which facilitates the recovery of the bone marrow hematopoiesis function.

This study compared and analyzed the prognosis of patients with T1-T2 breast cancer with one to three positive nodes after modified radical mastectomy with or without postoperative radiotherapy.

METHODSThe cases of 434 women patients with T1 to T2 breast cancer with one to three positive lymph nodes after modified radical mastectomy were reviewed, of which 196 patients received postoperative radiotherapy and 238 patients did not. The ipsilateral chest wall and supraclavicular fossa were irradiated with doses of 46-50 Gy in 23-25 fractions.

RESULTSFor all patients, the 3- and 5-year rates of overall survival (OS) were 94.7% and 85.7% respectively, local control (LC) 96.5% and 95.6%;, and disease-free survival (DFS) 89.3% and 82.3% respectively. The 3- and 5-year OS rates for patients without radiotherapy were 92.7% and 97.1% and for those with radiotherapy were 82.4% and 89.2%, both with significant differences (P = 0.039). The 3- and 5-year LC rates for patients without radiotherapy were 94.8% and 98.4% and for those with radiotherapy were 93.6% and 97.7%, again with significant differences (P = 0.041). The 3- and 5-year DFS rates for patients without radiotherapy were 87.8% and 91.3% and for patients with radiotherapy were 78.5% vs 86.1% (P = 0.047).

CONCLUSIONSPostoperative radiotherapy confers better rates of OS, LC, and DFS in patients with T1 to T2 breast cancer with one to three positive nodes after modified radical mastectomy.
