Objective To investigate the clinical significance and mechanism of WW domain containing oxidoreductase (WWOX) gene and p73 gene abnormal expression in acute lymphocytic leukemia (ALL).MethodsCase-control study was used in the research.Forty-eight cases of bone marrows from ALL patients were collected,including 32 cases newly diagnosed,11 cases with complete remission and 5 case with relapse.Thirty-one cases of bone marrows from non-leukemia patients were used as control group.All the samples were collected from First Affiliated Hospital of Guangxi Medical University from July 2010 to July 2011.The doctors punctured patients' bone marrows 3 milliliters from the left of posterior superior iliac spine.Samples were bottled up with EDTA anti-coagulation tube.1 milliliter bone marrow was used to extract genome RNA with purity from 1.8 to 2.0.And then,the level of WWOX and p73 gene transcripts were tested immediately using reverse transcriptase-polymerase chain reaction (RT-PCR).Meanwhile genome DNA was also extracted from the other 2 milliliter bone marrow with purity from 1.7 to 1.9,which was used to detect the promoter methylation of WWOX gene and the first exon methylation of p73 gene by methylation PCR (MS-PCP).x2 test and Fisher's exact test were used to compare tbe methylation status of WWOX and p73 gene.Results In 31 controls,expression of WWOX and p73 gene mRNA was 94.00％.The total expression frequency of WWOX gene mRNA in 48 ALL samples was 48.00％ (23/48),much lower than control (x2 =17.434,P =0.000 ).There was significant difference (x2 =10.471,P =0.001 ) between newly diagnosed cases 34.38％ ( 11/32),complcte remission cases (90.91％,10/11 ) and control.The total expression frequency of p73 gene mRNA in 48 ALL samples was 56.00％ (27/48),much lower than control (x2 =12.697,P =0.000).There was significant difference (P =0.012 ) between newly diagnosed cases 43.75％(14/32) and complete remission cases 90.91％(10/11).It was unmethylation in 31 controls.The total methylation frequency of WWOX gene promoter region in 48 ALL samples was 44.00％(21/48),much lower than control (x2 =18.473,P =0.000).There was significant difference (P =0.012) between newly diagnosed cases 56.25％ (18/32),complete remission cases 9.09％ (1/11 ) and control.The total methylation frequency of p73 gene the first exon region in 48 ALL samples was 35.00％(17/48),much lower than control (x2 =13.990,P =0.000).There was significant difference (P =0.033) between newly diagnosed cases 46.88％ (15/32),complete remission cases 9.09％ ( 1/11 ) and control.There was a negative correlation between the expression of WWOX gene mRNA and its methylation status(r =- 0.678,P =0.000),the same as p73 gene ( r =- 0.577,P =0.000).ConclusionsThe abnormal methylation of WWOX and p73 gene may be the major mechanism of gene silence in ALL,which leads to no expression of WWOX mRNA or p73 mRNA.And the abnormal methylation of WWOX and p73 gene may be relevant with the process of occurrence and development in ALL.It may be an effective and significant to detect methylation status of WWOX gene and p73 gene for the diagnosis and treatment of ALL patients.(Chin J Lab Med,2012,35:820-825)

In this paper, literature about adverse reaction induced by Puerarin injection published in recent years were reviewed and analyzed. It was reported that Puerarin injection can not only induce adverse reactions on multiple systems, such as immune, blood, urinary, digestive and cardiovascular system, but so far as to cause death. Therefore, it should be administered rationally and strictly according to the direction and the course of medication should be rigorously monitored to prevent the occurrence of adverse reactions.

OBJECTIVE:To evaluate the clinical efficacy of liraglutide and insulin glargine in the treatment of type 2 diabetes mellitus (T2DM) and conduct pharmacoeconomic analysis, and to provide economical and reasonable T2DM treatment plan. METHODS:80 T2DM patients were randomized into liraglutide group and insulin glargine group,with 40 cases in each group. Both groups were given Metformin hydrochloride sustained-release tablet orally 0.5-2.0 g/d,and diabetes mellitus diet and sport training guide after oral antidiabetic drug withdrawal of previous treatment plan. Liraglutide group was given Liraglutide injection hypodermically,0.6-1.2 mg,qd;insulin glargine group was given insulin glargine hypodermically at 22 o’clock,initial dose of 0.2 IU/(kg·d),adjusted according to the levels of PG,FBG,nocturnal blood glucose level till FBG≤7 mmo1/L and 2 h PG ≤10 mmol/L in both group. Treatment course of 2 groups lasted for 12 weeks. The changes of FBG,2 h PG,HbA1c and BMI were ob-served in 2 groups before and after treatment. 2 therapy plans were evaluated and compared by cost-minimization analysis. RE-SULTS:After treatment,the levels of FBG,2 h PG and HbA1c decreased significantly in 2 groups,compared to before treatment, with statistical significance (P<0.05),but there was no statistical significant difference between 2 groups (P>0.05). After treat-ment,BMI of liraglutide group decreased significantly compared with before treatment and insulin glargine group,with statistical significance (P<0.05). There was no statistical significant difference in BMI of insulin glargine group before and after treatment (P>0.05). Cost-minimization analysis showed that the cost of insulin glargine group in reducing FBG,2 h PG and HbA1c were less than liraglutide group,but were more than liraglutide group in reducing BMI. Sensitivity analysis demonstrated the stability and reliability of cost-minimization analysis. CONCLUSIONS:Lira-glutide and insulin glargine have the same clinical efficacy,but insulin glargine need lower cost in blood glucose control,and liraglutide is better therapy plan for body weight control.

Objective:To explore the effect of group psychotherapy on damage of theory of mind (TOM) in patients with early-onset schizophrenia.Methods:Totally 60 patients with early-onset schizophrenia were included and divided into the intervention group (n ＝ 30) and the health education group (n ＝ 30).The patients in the intervention group were offered 10 twice a week 2-hour sessions of group psychotherapy,and those in the control were offered group health education twice a week.All participants completed baseline measures and post-intervention measures with the Eye Emotion Recognition and Theory of mind Picture-sequencing Task (TOM-PST).Results:Totally 23 patients in the intervention group and 29 patients in the health education group finished the post-intervention measures.After 5-week intervention,subscores of sad and fear and total score of emotion recognition,total score of TOM-PST,understanding first order error belief,second order error belief,third order error belief,sense of reality,detecting fraud compared to baseline had statistically significant difference in intervention group.In health education group,subscores of joy emotion recognition,understanding first order error belief,third order error belief,total score of TOM-PST compared to baseline had statstically significant difference.The patients with group psychotherapy got higher scores of total score of TOM-PST and understanding second order error belief and third order error belief than the health education group after 5-week intervention (P ＜ 0.05).Conclusion:This study suggests the group psychotherapy could partially improve theory of mind with early-onset schizophrenia,and promote the recovery of social cognition.

OBJECTIVETo determine the significance of MSCT perfusion scan on differentiation of NSCLC and to investigate its possible mechanisms.

METHODSForty four NSCLC patients underwent CT perfusion scan by MSCT. Among them, 22 cases were selected to detected the two-dimensional tumor microvascular architecture phenotype (2D-TMAP), the relationships between CT perfusion parameters (BF, BV, PEI, TIP), and the differentiation of NSCLC were analysed by using the correlation analysis and trend test. Spearman correlation analysis was used to study the relationships between CT perfusion parameters, differentiation, and 2D-TMAP.

RESULTSThe total BF, BV and PEI decreased with decreasing differentiation of NSCLC (P<0.05). The total PEI showed a positive correlation with the total MVD (P<0.05). There were negative correlations between the surrounding area BF, the total BF, BV, and PEI, the uncomplete lumen of the surrounding area MVD, and expression of PCNA, respectively (P<0.05). There were positive correlations between degree of differentiation and the uncomplete lumen of the surrounding area MVD (P<0.05). It was the same as degree of differentiation and expression of PCNA, VEGF, respectively. There were positive correlations between the uncomplete lumen of the surrounding area MVD and expression of VEGF, ephrinB2, EphB4, and PCNA, respectively (P<0.05).

CONCLUSIONPerfusion parameters reflect the difference of density of vassels with mature functional lumen. Careful evaluation of the differences of blood flow pattern in pulmonary space-occupying lesions by MSCT perfusion scan can be used to identify the degree of NSCLC differentiation.

OBJECTIVETo investigate the role of the expression of ephrinB2 and EphB4 in non-small cell lung cancer (NSCLC), and their relationship with multi-slice spiral CT pulmonary perfusion imaging.

METHODSThirty-one nodules with pathologically proven NSCLC underwent CT perfusion scan. The perfusion parameters including blood flow (BF), blood volume (BV), peak enhancement image (PEI) were collected. The expression of ephrinB2 and EphB4 in tumor cells and interstitial vasculature were detected by immunohistochemistry. Correlation analysis and trend test were used to assess the relationship between ephrinB2/EphB4 expression and clinicopathological features, and between ephrinB2/EphB4 expression and perfusion parameters.

RESULTSPositive expression of ephrinB2 and EphB4 in the NSCLC group was 83.9% and 71.0%, respectively, significantly higher than that in the internal control group (P < 0.01). The expression of ephrinB2 and EphB4 was consistently in tumor parenchyma but differently in tumor vessels. The expressions of ephrinB2 and EphB4 were positively correlated with lymphatic metastasis (P < 0.05). The expression of EphB4 was negatively correlated with blood flow (BF) and blood volume (BV), respectively (P < 0.05). There was a significant positive correlation between ephrinB2 expression and BF (r = 0.516, P = 0.003), and a positive correlation between ephrinB2 expression and BV (r = 0.448, P = 0.013). The expressions of ephrinB2 and EphB4 were not correlated with PEI (P > 0.05). The values of BF and BV in the high and moderate EphB4 expression groups were significantly decreased compared with that in the negative group (P < 0.01). The value of BF in the high ephrinB2 expression group was significantly increased compared with that in the moderately positive group and negative group (P < 0.01). The value of BV in the high ephrinB2 expression group was significantly increased compared with that in the negative group (P < 0.01).

CONCLUSIONThe CT pulmonary perfusion imaging reflects the density difference of blood vessels with functional lumen, and such difference also depends on the quantity and quality of vasculature with functional lumen.

The objective of study was to investigate the in vitro suppressive effect of angelica polysaccharide (APS) on human cytomegalovirus-induced apoptosis via direct infection in CHRF-288-11 cells. HCMV AD169 directly infected CHRF-288-11 were cultured in vitro, APS in different doses were added on day 3 after the infection of virus. Cells of every group were collected at different time points. HCMV DNA of cells were detected by using polymerase chain reaction and the apoptotic cells were examined by using Hoechst staining, MTT assay, DNA fragmentation assay and flow cytometry. The results showed that the APS to some extent inhibited the apoptosis of CHRF cells infected by HCMV in vitro in a dose-dependent manner. The expression of HCMV IEA in CHRF-288-11 cells was found by PCR amplification. Morphology observation, flow cytometry assay and DNA fragmentation assay revealed the existence of apoptosis. With the dose decrease of APS added to the infected CHRF cells, the percentage of apoptotic cells increased. It is concluded that the HCMV AD169 can infect CHRF cells directly in vitro and decrease cell viability. HCMV AD169 infection increases the apoptosis of CHRF cells in time-dependent manner. When APS was added to the CHRF cells infected by HCMV AD169 in vitro, the viability of CHRF cells increase, which indicated that APS to some extent protects the CHRF cells infected by HCMV. APS suppresses the cytomegalovirus-induced apoptosis in CHRF cells directly infected in vitro in dose-dependent manner.
