Objective:To determine the derivative chromosome 9 by the method of detecting the ASS gene,and to explore the relationship between the deletion of derivative chromosome 9 and the efficacy and prognosis of the chronic myeloid leukemia (CML)patients. Methods:The materials of 34 CML patients with positive BCR-ABL fusion gene whose ASS genes were detected were retrospectively analyzed. All patients were treated with Extra-signal (ES)probe to detect the derivative chromosome 9.All patients were divided into two groups according to whether they carried the derivative chromosome 9.The blastic phase or the accelerated phase rates in two groups were compared by using Fisher exact probability. Results:All patients were detected by FISH (BCR-ABL ES probe),and all the BCR-ABL fusion signals were positive.6 of 34 patients were found the deletion of ASS gene, among them 1 case blonged to chronic phase,and 5 cases developed into blastic phase or accelerated phase. In the patients without ASS gene deletion,there were 22 cases in chronic phase,and 6 cases in plastic phase or accelerate phase,there was significant difference of blastic phase rate/accelated phase rate between them (P<0.05).A total of 26 patients were treated with tyrosine kinase inhibitors (TKI).5 of 26 patients belonged to the ASS gene deletion group,1 of 5 patients treated with TKI got molecular remission,4 of 5 patients developed into blastic phase or accelerated phase.21 of 26 patients belonged to the group without ASS gene deletion,and among them,19 cases got molecular remission,2 cases developed into plastic phase or accelerated phase after treatment of TKI,there was significant difference between them (P < 0.05 ). 6 patients were treated with traditional chemotherapy (hydroxyurea,interferon);1 of 6 patients belonged to the ASS gene deletion group,finally developed into the blastic phase or accelerated phase;5 of 6 patients belonged to the group without ASS gene deletion,2 cases got the hematological remission,and 3 patients developed into blastic phase or accelerated phase after treatment,and there was no significant difference of blastic phase rate/ accelerated phase rate between them (P > 0.05 ). Conclusion:The CML patients with derivative chromosome 9 (ASS gene deletion)prone to get disease progression, and have a higher proportion in the blastic phase or accelerated phase patients.Derivative chromosome 9 is related to the bad treatment efficacy of TKI and the poor prognosis of CML.

Hemopexin (HPX) is a plasma protein with the strongest binding capacity to heme and widely involved in modulation of a variety of physiological and pathological processes. The main physiological function of HPX is to bind and transport free toxic heme. Recent studies indicate that HPX also plays roles of anti-oxidant, anti-apoptosis, immune regulation and organic protection. In addition, HPX participates in regulation of cell differentiation and extracellular matrix reconstruction. In recent years, a great deal of progress has been made in studies of the mechanisms of HPX protective effects and on possible clinical application. In the past few years, especially, a number of proteomic studies have demonstrated that HPX could be served as positive molecular biomarkers for cancers of lung, liver, kidney, colon, and uterine myoma as well as osteoarthritis. In this review, recent progress in the biochemical characteristics and function of HPX and its possible clinical applications are summarized.

Objective To study the characteristic of inhibition on platelet P2Y12 and short-term change after clopidogrel intake in patients with cardiovascular disease. Methods Thirty-two patients with cardiovascular disease were enrolled. Samples at baseline, 10 h and 36 h after 300 mg loading dose and 75 mg/d maintenance dose of clopidogrel with 100 mg/d Aspirin intake were measured respectively. Platelet aggregation (PAgT) was measured on thromboelastograph(TEG) induced by ADP/AA. INH was detected and calculated activated by Kaolin, AA, ADP and Activator((R)) in the TEG reagent. CD62p and VASP phosphorylation (PRI), platelet activation markers were tested with FACSCalibur Flow Cytometry, and platelet secretion activity and suppression of P2Y12 receptor were detected respectively. The changes of indicators were compared before and after clopidogrel intake, and evaluate their function in platelet receptor activation. Results INHADP at baseline was (11.5 ±9.3)%, and increased to (42.5 ±29.1)% statistically (t =3.155, P<0.05) after taking the P2Y12 at 10 h, but decreased to (20.4±13.1)% at 36 h, non-statistical to baseline (t = 2.078, P > 0. 05) , INHAA increases from baseline level (56. 6 ± 36. 6) % to (83.0 ±27. 3)% at 10h(t=2.086,P>0.05) and (85. 4 ±20. 8)% at 36 h (t= 1. 888, P>0.05), no statistical defferences were found. Inhibition on platelet activativation induced by ADP function well till 36 h after 300 mg loading dose. PAgTADP decrease from (53. 7 ± 14. 1)% at baseline to (49. 2 ±22. 8)% at 10 h non-statistically (t=0.656, P>0.05), and (40.7±12.8)% at 36 h statistically (t=2.418, P<0.05), however PAgTAA decrease at both 10 h and 36 h statiscally, from (34. 3 ± 18. 1) % to (17.4 ± 13. 1) % , (t=3.134, P<0.05) and (14.6±5.1)%, (t=2.532, P<0.05), respectively. Data of PAgT was not corresponding to that from TEG for the difference in sample type partly. PRI in VASP assay was (78. 6 ± 22.3)% before loading dose, and decreased to (70.7 ±9.4)% at 10 h without significance (t = l. 194, P>0.05) and (59.6 ±28.0)% at 36 h (t=1.930,P<0.05) statistically, similarly to INHADP,indicating that within 36 h clopidogrel did not have strong inhibitory effect on the ADP receptor. On the contrary, CD62p changed from (7. 5 ± 1. 4) % at baseline to (4. 2 ± 1. 1) % statistically (10 h, t = 18. 027, P < 0. 05) and ( 4. 3 ± 0. 2 ) % non-statistically (36 h, t = 2. 908, P > 0. 05 ). Inhibition of secretion activity reflected by CD62p was significant. In contrast, it was more obvious inhibition in COX-1 passway, while the inhibition of P2Y12 receptor varied due to assay difference. Conclusions AA-induced platelet activation is significantly decreased in the inhibition of clopidogrel and aspirin, while ADP receptor is significantly inhibited until 36 h after the loading dose of clopidogrel. Platelet function in whole blood reflects total activity of platelet interaction with other components, in which no significant inhibition could be witnessed within 10 h.

OBJECTIVETo compare the difference in the clinical efficacy on premature ovarian failure (POF) between the acupoint catgut implantation combined with artifical periodic therapy and the simple artificial periodic therapy and explore its effect mechanism.
METHODSSixty-five patients of POF were randomized into the two groups. In a western medication group, 32 cases were treated with the artificial periodic therapy with the oral administration of medroxyprogesterone acetate tablets. In a catgut implantation + western medication group, 33 cases were treated with the acupoint catgut implantation combined with artificial periodic therapy. The acupoints of Neiguan (PC 6), Zusanli (ST 36), Guanyuan (CV 4) and Sanyinjiao (SP 6) were selected. The treatment was lasted for half a year and the follow-up visit was for another half a year in the two groups. Kupperman index was used to assess the improvements in the clinical symptoms. The levels of serum sexual hormones such as follicle stimulating hormone (FSH) and estradiol (E2) were evaluated of the patients in the two groups before and after treatment. The efficacy was compared between the two groups.
RESULTSThe scores of the clinical symptoms were all significantly improved after treatment and in the follow-up in the two groups (P < 0.01, P < 0.05). In the 6-month follow-up visit after treatment, the result in the catgut implantation + western medication group was better than that in the western medication group (8.17 +/- 1.19 vs 13.68 +/- 1.08, P < 0.01). FSH was reduced after treatment in the two groups (all P < 0.01) and E2 was increased (all P < 0.05). The curative and remarkably effective rates were 75.8% (25/33) and 81.8% (27/22) after treatment and in the follow-up visit in the catgut implantation + western medication group, which were better than 67.9% (19/28) and 53.6% (15/28) in the western medication group separately (P < 0.05, P < 0.01).
CONCLUSIONThe acupoint catgut implantation combined with artificial periodic therapy achieve the remarkable improvements in the clinical symptoms of POF in the patients and the better results as compared with the simple western medication therapy. The combined therapys efficacy is stable and the long-term efficacy is apparently superior. The effect mechanism is related to the improvements in the serum sexual hormone levels.

During the washing process of coarse bear gall powder extracts, it is necessary to adjust the amount of ethyl acetate according to the properties of raw materials, which aims to improving the yield and purity of the final product. In the research, using NIR spectra to reflect the comprehensive properties of coarse bear gall powder extracts, the process is optimized in a flexible way. Forty batches experiments are designed according to the weight ratio of ethyl acetate and coarse extracts of bear gall powder. The NIR spectra of the coarse extracts of bear gall powder are collected and processed using principal component analysis (PCA) method. The first 8 principal components combined with the amount of the ethyl acetate are used as the input variables, and calibration models are established to predict the yield and purity of the final product 30 batches are used as calibration set, which is used to establish the models, and other 10 batches are used as validation set, which is used for the performance appraisal of the established models. The correlation coefficients of the calibration, inner cross-validation and external validation for the purity model are 0.902, 0.896 and 0.883, respectively, and the RMSEC, RMSECV and RMSEP are 1.22%, 1.48% and 1.59%, respectively. The correlation coefficients of the calibration, inner cross-validation and external validation for the yield model are 0.921, 0.859 and 0.916, respectively, and the RMSEC, RMSECV and RMSEP are 1.39%, 1.65% and 1.53% respectively. This work demonstrated that NIR spectra combined with technology parameter could be used to predict the yield and purity of the final product. Using the established models, the most appropriate amount of the ethyl acetate can be determined according to the properties of the coarse bear gall powder extracts, and the yield and purity of the final product can be improved.
