Objective To investigate the sensitivity of BIOMED-2 primer system in adult acute lymphoblastic leukemia (AIJ,) patients Ig gene rearrangement, and to analyze their frequency, corearrangement pattern, utilization of V, D and J genes and composition of junctional regions. Methods Amplification of rearranged IgH (complete and incomplete), IgK, IgK-Kde and IgL was performed in standard PCR in 29 adult ALL patients. Monoclonal PCR products were subjected directly to DNA sequencing. Sequences were identified by comparison with all known human Ig germline sequences to analyze the recombination patterns, somatic mutations and germline gene segments usage. Results IgH, incomplete IgH, IgK, igK-Kde and Igl, rearrangements were found with positive rate of 70.8%, 12.5% , 29.2% , 25.0% and 0 of B-ALL patients, respectively. All B-ALL patients displayed at least one pattern of Ig gene rearrangements. In TALL, one of five patients was found with incomplete IgH rearrangement, two patients were found with IgK rearrangements and two patients were PCR-negative. The sequence analysis showed that the most frequently used V, D, J segments in adult B-ALL patients were from VH3/VH4 families, DH3 family and JH6 family, respectively. Four of five IgK rearrangement used VκI family. 23.5% B-ALL IgH contained scattered replacement mutations with replacement to silent substitution ratio < 1 in complementarity determining regions. Conclusion BIOMED-2 multiplex PCR analysis strategy is a reliable and useful technique in the adult BALL patients.

Objective To evaluate the quality of life (QOL ) of chronic hepatitis B (CHB) patients and to explore its related factors .Methods SF‐36 questionnaire was used to evaluate the QOL of 626 CHB patients visited or hospitalized in China‐Japan Friendship Hospital from July 2014 to June 2015 .And the residents around the hospital were included as control group .Sociological characteristics ,clinical data , health related behaviors and nutritional status were collected .Logistic regression analysis was used to analyze the factors related to quality of life . Results Six hundred and twenty‐six participants were enrolled in each group ,including 424 males and 202 females .The average age of CHB group and control group were 44 .2 ± 13 .9 and 44 .2 ± 13 .9 ,respectively .The average QOL score of the CHB patients was 72 .25 ± 16 .06 ,and 8 dimensions and 2 domains of CHB group were lower than those of control group (both P < 0 .05 ) . In multivariate analysis , factors independently associated with higher physical component summary (PCS) score were younger age (18—45 years old:OR=0 .27 ,95% CI:0 .13—0 .54 ;45—60 years old :OR= 0 .47 ,95% CI:0 .23—0 .95) ,high‐quality sleep (OR= 0 .20 ,95% CI:0 .12—0 .33) ,frequent exercise (OR=0 .37 ,95% CI:0 .19—0 .73) or occasional exercise (OR=0 .49 ,95% CI:0 .30—0 .77) ,and mild hepatitis symptoms (mild:OR=0 .19 ,95% CI:0 .05 -0 .76 ;moderate :OR=0 .20 ,95% CI:0 .06—0 .68 ) , while disease duration was associated with lower PCS score ;factor independently associated with higher mental component summary (MCS) score was high quality sleep (OR=0 .25 , 95% CI:0 .16—0 .41) ,while longer duration (OR= 14 .04 ,95% CI:1 .81—109 .38) and lower weight (OR=2 .72 ,95% CI:1 .48—4 .98) were associated with reduced MCS score ( all P<0 .05) .Conclusions The QOL of CHB patients is damaged universally .More attention should be paid to the health related life behavior and nutritional status of CHB patients in the future management .

7% (OR=4.640,95%CI=1.064 to 20.239,P=0.041) were the high risk factors for myocardial ischemia in patients with type 2 diabetes.Conclusion Poor control of the 4 factors is the high risk factor for myocardial ischemia in patients with type 2 diabetes.Overall and effective control of such risk factors can decrease the incidence of myocardial ischemia and improve its treatment.

Corneal endothelial cell(CEC)is the most critical part for the cornea, of which activity can influence the postoperative vision.It is very important for the clinical cornea preservation considering the function and its self-purification of donor cornea.There are a variety of classical methods, which can significantly prolong the saving time of donor cornea with its good quality of CEC.We reviewed the published papers about present preservation methods of cornea, which can give us many suggestions for the clinical cornea preservation.

Knee osteoarthritis (KOA) is a common degenerative joint disease. Biomechanics of lower extremity plays an important role in KOA. Foot progression angle, with the advantages of non-invasive, convenience, has been attached great importance by people gradually. Changing foot progression angle may effect the knee adduction torque, tibia rotation, muscle activity, which leads to change the load of the knee joint, and alleviate the pain, improve the function of knee joint and the quality of life of the patients.

The impact of acupuncture for the pregnancy of in vitro fertilization-embryo transfer (IVF-ET) is discussed in the paper. Nowadays there are various conclusions about the impact of acupuncture for IVF-ET, and it may result from the differences in research designs. The effect is closely related to the demographic and clinical characteristics of subjects, such as age, the diagnosis of barrenness, blood flow index of uterine spiral arteries, the cycle of IVF, etc. Besides, the efficacy is influenced by treatment based on syndrome differentiation or not, the frequency and course of acupuncture in both the treating group and the control group, etc. If more reasonable design is achieved in the further study based on them, more reliable evidence will be provided for the effect and mechanism of the pregnancy of IVF-EF by acupuncture.

This study discusses the effects of Shenlian extracts (SL) on M1 macrophages in atherosclerosis. The MTT assay was used to detect the growth inhibition rates of RAW264.7 cells. RAW264.7 cells were stimulated with murine interferon-gamma (IFN-gamma) plus lipopolysaccharide (LPS) to induce M1 macrophages. The different concentrations of SL extracts (high-dose 50 mg x L(-1), moderate-dose 25 mg x L(-1), low-dose 12.5 mg x L(-1)) were added. The CD86 of M1 macrophages in cell membrane was measured by flow cytometry. The mRNA expression of iNOS and TNF-alpha gene was detected by reverse transcription PCR (RT-PCR). And the supernatants were collected, the content of IL-6 and TNF-alpha were detected with ELISA kits. The results of this experiment show that the expression of the cell membrane molecule CD86, iNOS and TNF-alpha gene, the content of IL-6 and TNF-alpha was obviously increased in M1 macrophages by IFN-gamma and LPS. The different doses of SL extract could reduce the expression of the above indicators. The above experimental results demonstrate that IFN-gamma combined LPS can induce RAW264.7 cell to type into M1 macrophages, and SL extracts can inhibit M1 macrophages.
