Objective Explore the feasibility of minute cells STR typing.Methods Minute cells which were obtained by micromanipulation method were amplified with MiniFiler kit,and detected by ABI 3130 genetic analyzer.Results Ten cells can be successfully genotyped.Complete genotyping results can be obtained for one,three or five cells but with stochastic effect.Conclusion Instability is observed in minute cells genotyping,so it can not be used in actual case work.Maybe increase the quantity of DNA template can improve the success rate.

Objective To explore the expression and mechanisms of MMP-9 in vascular remodeling of two-kidney and one-cliped hypertension rats. Methods Male Wistar rats were randomly divided into sham operation group( n = 10), two-kidney and one-clip model (2KIC) group ( n = 10) and telmisartan group ( n = 7 ). Telmisartan group were injected with telmisartan every day. The blood pressure was determined every week. The morphologic change of carotid artery and thoracic aorta was observed with HE stainning 8 weeks after treatment with telmisartan.Arteries was performed to evaluate the expression of MMP-9 with immunohistochemisty. Results The blood pressure,vessel wall,and the expression of MMP-9 in model group were significantly higher than that of control group.Telmisartan nearly normalized arterial pressure and suppressed all these changes. Conclusion MMP-9 was related to vascular remodeling and Telmisartan could regulate vascular remodeling in 2-kidney and 1-cliped hypertension rats by inhibiting the pathway of MMP-9.

Objective To investigate the staging significance of PET-CT in multiple myeloma,and to observe the relationship between baseline PET-CT and clinical parameters in multiple myeloma.Methods 78 cases newly diagnosed MM patients were selected from the Department of Hematology,the Xinjiang Uygur Autonomous Region people's Hospital from March 2007 to February 2014,with average age 61.24 years old.The levels of hemoglobin,albumin,beta 2 microglobulin and lactate dehydrogenase were detected before the treatment.PET-CT was performed to measure SUVmax in the spine,pelvis and rib with an average of the SUVmax in each case,and the number of FDG-avid focal lesions in every patient was counted.The difference of the SUVmax or FLS in different stages and the relationship between SUVmax or FLS and clinical parameters in MM were observed.Results All the patients were divided into 3 stages depending on ISS staging.The average SUV values in 10 cases of stage Ⅰ,45 cases of stage Ⅱ and 23 cases of stage Ⅲ were 1.84±0.28,3.74±0.42 and 6.02±0.93,respectively,and SUV values was significantly different among different groups (P ＜ 0.05).SUV values were positively correlated with levels of beta 2 microglobulin (r =0.862,P ＜ 0.001) and lactate dehydrogenase (r =0.592,P ＜ 0.001),and negatively correlated with albumin (r =-0.762,P ＜ 0.001) and hemoglobin levels (r =-0.685,P ＜ 0.001).The number of lesions had a correlation with low hemoglobin,high lactate dehydrogenase and high beta 2 microglobulin (P ＜ 0.05).Conclusion PET-CT can reflect tumor burden to some extent,and has the guiding significance for MM stage,which contributes to developing individualized treatment programs.

Objective To evaluate the cytogenetic, molecular responses and safety of generic imatinib in newly diagnosed patients with chronic myelogenous leukemia in chronic phase (CML-CP) in 1-year at different stages. Methods From January 2014 to November 2014, 50 CML-CP patients received oral generic imatinib 400 mg/d. The cytogenetic examinations, bcr-abl transcript levels and safety were monitored after 3, 6, 9 and 12 months respectively. Results 46 of 50 patients insisted on oral generic imatinib and followed up 1 year. At 3-month, 52.0 % (26/50) patients reached the complete hematologic responses (CHR) rate, and patients at least achieved minor cytogenetic response (mCyR) and bcr-ablIS≤10 % were 84.0 % (42/50) and 42.0 % (21/50). At 6-month, patients at least achieved part cytogenetic response (PCyR) and bcr-ablIS≤10 %were 73.5 % (36/49) and 59.2 % (29/49). At 12-month, patients achieved complete cytogenetic response (CCyR), bcr-ablIS≤1 % and bcr-ablIS≤0.1 % were 60.9 % (28/46), 63.1 % (29/46) and 45.7 % (21/46). The grade 3 leukopenia, thrombocytopenia and anemia rates were 34 % (17/50), 40 % (20/50) and 30 % (15/50), respectively. No grade 4 hematologic toxicity occurred. The common non-hematologic toxicities included edema [84 % (42/50)], nausea [46 % (40/50)], muscle pain [20 % (10/50)], rash [16 % (8/50)], and impaired liver function [8 % (4/50)]. Conclusion Generic imatinib has a favorable effect in treatment of patients with CML-CP, and without serious adverse reactions.

Granulocyte colony-stimulating factor (G-CSF) has been demonstrated to have neuroprotective effects in rat model with focal cerebral ischemia through anti-apoptotic pathways and by promoting proliferation of neural stem cells. In the present study, we examined the neuroprotective effect of G-CSF in an acute focal cerebral ischemia rat model with lipid metabolism disorder. Eighty male SD rats were randomly divided into normal diet control group (NC group) and high-fat diet group (HFD group) (n = 40 in each). In HFD group, rats were fed on high fat diet to induce atherosclerosis. After 29 days, 4 rats from each group were sacrificed to evaluate the effects of different diets, and the middle cerebral artery occlusion (MCAO) was performed in the rest of the rats. MCAO rats received either G-CSF (50 μg·kg(-1)·mL(-1)) or phosphate buffered saline (PBS) injection through the external jugular vein for 5 days, which was followed by 5-bromo-deoxy uridine (BrdU, i.p., 50 mg/kg) injection for another 7 days. To evaluate the effects of G-CSF treatment on neurological function, the modified neurological severity score (mNSS) was calculated. The vascular distribution, ischemic cells proliferation, cell apoptosis and the expression of vascular endothelial growth factor (VEGF) were measured to determine the effects of G-CSF treatment. Our results showed that G-CSF-treated rats had a lower mNSS than PBS-treated rats in both NC group and HFD group. G-CSF injection promoted endothelial cell proliferation and vascular regeneration, and inhibited cell apoptosis. The serum and tissue levels of VEGF were significantly increased after G-CSF treatment. It is concluded that G-CSF exerts its neuroprotective effect in focal cerebral ischemia rats with hyperlipidemia by enhancing angiogenesis, promoting cells proliferation, decreasing cell apoptosis, and increasing local VEGF expression.

Objective To analyze the ABCD1 gene mutations in 5 cases of X-linked adrenoleukodystrophy(X-ALD) patients and 2 cases of their mothers.Methods Of 5 patients with X-ALD,10 exons and flanking intronic sequences of ABCD1 gene were amplified by polyme-rase chain reaction,and then sequenced directly.The outcomes were compared with normal ABCD1 sequencings to identify the mutation type and site.Thirty normal men were examined in the mean time as control for the confirmation of mutations and gene polymorphisms.Results Three patients showed ABCD1 gene mutations,1 had a point mutation in exon 6,Arg518Gly(CGG→GGG);2 patients showed the same novel mutation in exon 1 with 8 bases deletion(134del8).Four gene polymorphisms were identified in exon 7.They were Gly551X(GGC→GGT),Arg554His(CGT→CAT),Gln567Arg(CAA→CGA) and Val582Ile(GTC→ATC).ABCD1 gene mutation was not found in 2 mothers from 2 unrelated fa-milies with X-ALD.Conclusions Three cases of 5 were detected for ABCD1 gene mutations.Between them,the 134del8 mutation is a novel one.Four new gene polymorphisms were detected in exon 7 in normal Chinese people,which were Gly551X,Arg554His,Gln567Arg and Val582Ile.
