Objective To morphologically evaluate the bone marrow (BM) smear specimens collected from the patients with chronic myelogenous leukaemia (CML) in accelerated phase and blastic phase receiving a short term Gleevec therapy, and to determine its clinical significance in evaluating the changes in disease condition to guide the treatment. Methods Sequential BM smear specimens of 16 Ph positive CML patients, including 9 in accelerated-phase and 7 in blastic-phase, were examined before and 3,6 and 9 weeks after Gleevec treatment (0.4/d or 0.6g/d, PO) with routine method. Periodic acid-Schiff reagent (PAS) staining was performed for a proper identification of abnormal erythroid precursor cells. Results The treatment rapidly caused following conspicuous BM changes in the process: both cellular proliferation and neutrophil granulopoiesis decreased significantly, while the accumulation of erythroid precursor cells increased obviously, and megakaryocytes decreased markedly at 3rd week. A few patients showed no such changes, but an accumulations of erythroid precursor cells, leading to misdiagnosis in some one third of the patients. In 21 percent of patients, in whom no erythroid cells were found, were classified into accelerated phase and blast phase based on both WHO classification system and FAB system. In fact the increase in red system was a bone marrow response to anemia caused by Gleevec therapy. If a condition of severe cellular proliferation of BM with a lower WBC and platelets appeared, most patients could not tolerate the therapy, then it should be ceased. Conclusion Initial treatment with Gleevec therapy exerts pronounced changes in BM morphology, which can be used as a simple and effective method to evaluate the outcome of the patients.

To clarify the origin and development of the traditional Chinese medicine "Duhuo" and "Qianghuo" with medicinal literatures. Medical literatures of past dynasties were analysed and combined with the modern material. The "Duhuo" in Herbal writing Shen Nong Ben Cao Jing include traditional Chinese medicine "Duhuo" and "Qianghuo", "Qianghuo" was separated from "Duhuo" due to the distinguish of clinical application. The origin of "Qianghuo" is Notopterygium incisum and N. forbesii, However, The origin of "Duhuo" is very complex, Angelica pubescens f. biserrata as authentic "Duhuo" was used from Song Dynasty. "Qianghuo" was originated from "Duhuo".

Objective:To investigate the variations in ocular biometry and its influencing factors in adult Tibetans of Lhasa.Methods:A cross-sectional study was adopted.A total of 100 consecutive adult Tibetans (100 eyes) with cataract, who were treated in Tibet Autonomous Region People's Hospital from March 2017 to July 2017 were enrolled, including 51 males and 49 females, with an average age of (63.38±12.80) years.The subjects were divided into two groups, with 57 subjects (57 eyes) older than 60 years in the elder group and 43 subjects (43 eyes) younger than 60 years in the youth group.Corneal curvature, corneal astigmatism, anterior chamber depth and axial length of subjects were measured and compared with those of Beijing population which were used as standardized data of Han Chinese.The differences in ocular parameters associated with age and gender were analyzed.This study adhered to the Declaration of Helsinki.The study protocol was approved by an Ethics Committee of Tibet Autonomous Region People's Hospital (No.ME-TBHP-21-KJ-005).Written informed consent was obtained from each subject prior to any examination.Results:The mean corneal curvature, corneal astigmatism, anterior chamber depth and axial length of the 100 Tibetans were (43.68±1.62)D, 0.750 (0.375, 1.000)D, (3.05±0.41)mm, (23.07±0.86)mm, respectively.The axial length of Tibetan was shorter than that of Beijing Han people and the difference was significant ( t=2.65, P<0.01).Corneal astigmatism of the elder group was higher than that of youth group and the difference was significant ( t=2.11, P<0.05).There were no significant differences in corneal curvature, anterior chamber depth and axial length between the elder group and youth group (all at P>0.05).The anterior chamber depth and axial length of males were much longer than those of females, and the differences were significant ( t=2.71, 2.25; both at P<0.05). Conclusions:In adult Tibetan population, the axial length is short, and the anterior chamber is deep.The corneal astigmatism increases with age and there is a gender difference in axial length and anterior chamber depth.

Objective To determine the effects of urapidil on L-type calcium current(I_(Ca-L))in rat cardiomyocytes.Methods Ventricular myocytes were isolated from SD rats of either sex(250-280g)by retrograde perfusion of the hearts via aorta with calcium-free Tyrode solution containing enzyme as described elsewhere.Rod shaped cells with clear borders and striations were selected.Eighteen cells were randomly divided into 3 groups(n =6 each):A urapidil group;B urapidil+methysergide group and C methysergide group.All the cells in the three groups were peffused first with Tyrode solution for 1 min(T_1).In group A and C cells were then peffused with Tyrode solution containing 0.4 ?mol?L~(-1) urapidil(A)or 40 nmol?L~(-1) methysergide(C)for 1 min(T_2) while in group B cells were perfused fwst with Tyrode solution containing 0.4 ?mol?L~(-1) urapidil for 1 min (T_2) then with Tyrode solution containing methysergide 40 nmol?L~(-1) for 1 min (T_3).Finally the cells were again perfused with regular Tyrode solution for 1 min(T_4)to wash out the drugs.The peak of I_(Ca-L) was recorded at T_(1-4) by means of the whole cell patch clamp technique with use of Axo patch 200B.Results In group A,B and C the peak of I_(ca-L) at T_2 was significantly lower than that at T_1 but there was no significant difference between the peak of I_(ca-L) at T_1 and T_4.In group B the peak of I_(Ca-L) at T_3 was significantly lower than that at T_2.Conclusion Urapidil inhibits L-type calcium current in rat isolated cardiomyoeytes.It's inhibitory effect may not be mediated by 5-H_(1A) receptor.

Objective To investigate the effects of supported employment(SE) on the vocational rehabilitation for schizophrenic rehabilitants.Methods 108 schizophrenic rehabilitants with stable conditions were recruited and randomly allocated into the control group and experimental group.Fifty-four cases in the control group received the general outpatient service and follow-up service with drug maintenance therapy and 54 cases in the experimental group received SE with drug maintenance therapy.At the baseline and the end of the sixth month,all of the 108 cases were assessed by the Positive and Negative Syndrome Scale (PANSS) and Work-related Social Skills Scale (WSSS) respectively.The competitive employment rate and average working days of the two groups were evaluated at the end of the sixth month.Results There was no significant difference in the total score of WSSS,and the total score of PANSS and its sub-scores on the Positive Scale,Negative Scale and General Psychopathological Scale betweeu the two groups at the baseline(P＞ 0.05).At the cnd of the sixth months,significant differences (P＜0.01 ～ 0.05) were found in the total score of WSSS,the sub-score of the Negative Scale,the competitive employment rate and the average working days((35.11 ± 12.71) d vs(20.15 ± 8.04) d) between the experimental and control groups.Conclusion SE can increase the employment rate of schizophrenic rehabilitants,improve their abilities to acquire and maintain competitive employment,and meanwhile relieve their negative symptoms.
