ABSTRACT
Objective To explore serum long stranded noncoding RNA (lncRNA) transcript 1 (PCAT-1) expression level of patients with multiple myeloma (MM) and clinical value.Methods 72 cases of patients with MM treated in the Second People's Hospital of Zhaoqing City were selected as the study objects,and 60 cases of normal subjects undergoing physical examination in the same period were as the control group.Serum lncRNA PCAT-1 expression was detected by RT-PCR method.The relationship between lncRNA PCAT 1 expression and clinical pathological parameters,treatment effect was analyzed,and 5 years survival was analyzed by using Kaplan-Meier,and survival difference was detected by using Log-Rank method.Results Serum PCAT-1mRNA expression in MM group (2.65 ± 0.64) was significantly higher than that in the control group (1.06 ± 0.23,t=18.276,P=0.000).There were no significant differences in sex,clinical stage and pathological types of hemoglobin,plasma cells,platelets,albumin,β2-MG and CRP between PCAT 1 mRNA high expression group and low expression group (x2 =0.001 ～ 3.345,all P ＞ 0.05).Ca2+ ≥ 10 mg/dl in the PCAT-1 high expression group (57.14％) was significantly higher than that in the low expression group (27.27％,x2 =5.229,P=0.022).There was no significant difference in treatment effect between PCAT-1 mRNA high expression group and low expression group (88.64 ％ vs 75.00％,x2 =2.291,P=0.130).PFS and OS expression in PCAT-1 high expression group were lower than that in the low expression group (x2 =7.269,P =0.007;x2 =9.190,P =0.002).COX risk regression multiple factor analysis showed that age and PCAT-1mRNA expression were independent prognostic factors influencing patients (OR =3.275,P =0.025,95％CI:2.691～3.761;OR=2.136,P=0.046,95％CI:2.034～2.685).Conclusion LncRNA PCAT-1 is highly expressed in serum of patients with multiple myeloma,and correlated with the prognosis of patients.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the clinical effect and safety of chiropractic in treating cervicogenic sudden hearing loss.</p><p><b>METHODS</b>From January 2011 to October 2013, 90 patients with cervicogenic sudden hearing loss were randomly divided into treatment group and control group according to the random number table produced by SPSS 19.0 software. In the treatment group, there were 17 males and 28 females, aged from 31 to 62 years old with an average of (47.57±9.43) years; course of disease was from 1 to 3 days with an average of (1.43±0.68) days; pure-tone audiometry score was from 46.5 to 77.8 dB with the mean of (61.20±9.83) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 17 to 31 scores with an average of (23.46±7.18) scores. In the control group, there were 15 males and 30 females, aged from 28 to 64 years old with an average of (45.77±6.99) years; course of disease was from 1 to 3 days with an average of (1.50±0.73) days; pure-tone audiometry score was from 48.1 to 75.0 dB with the mean of (63.91±8.05) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 20 to 29 scores with an average of (25.61±10.43) scores. The patients of control group were treated with dexamethasone intravenous drip of 10 mg, 3 days later, decreased to 5 mg, 3 days again. And with the methycobal intravenous drip of 500 μg, treatment continued for 10 days. The patients of treatment group were treated with chiropractic additionally except for the therapeutic methods of control group. Chiropractic included local muscle loosening, attacking point, bilateral pulling atlanto-axial joint, and continuous treatment for 10 days. The pure-tone audiometry score and NPQ score were compared between two groups after treatment.</p><p><b>RESULTS</b>After the treatment, pure-tone audiometry score and NPQ score in treatment group improved to (40.23± 8.14) dB and (12.70±8.29) scores respectively, which were obviously better than that of control group's (37.70±10.61) dB and (21.24±11.13) scores (P<0.05).</p><p><b>CONCLUSION</b>Compared with routine method for cervicogenic sudden hearing loss, additional chiropractic can improve hearing and relieve neck pain effectively.</p>

<p><b>OBJECTIVE</b>To study the instructional significance of HBV-DNA load in maternal milk on breastfeeding of postpartum women infected with HBV.</p><p><b>METHODS</b>HBV-DNA levels in serum and breast milk were detected by FQ-PCR in 152 postpartum women infected with HBV, and HBV-DNA ≥ 1.0 × 10(3) U/ml was defined as HBV positive. Correlation analysis was also conducted to estimate if there were relations in HBV levels in serum and breast milk.</p><p><b>RESULTS</b>HBV-DNA positive rate were 50.66% (77/152) and 36.18% (55/152) in serum and breast milk, respectively. When HBeAg was positive, HBV-DNA positive rate were 95.38% (62/65) and 76.92% (50/65) in serum and breast milk; however when HBeAg was negative, HBV-DNA positive rate were 17.24% (15/87) and 5.75% (5/87) in serum and breast milk. When the concentration of HBV-DNA was 3-4 lg U/ml in serum, HBV-DNA positive rate was 20.00% (5/25) in breast milk; However, when the concentration of HBV-DNA was higher than 5 lg U/ml in serum, HBV-DNA positive rate was 96.15% (50/52) in breast milk.</p><p><b>CONCLUSION</b>The HBV-DNA level in breast milk in postpartum women infected with HBV increased with the HBV-DNA levels in serum. Breastfeeding should be avoided when the concentration of HBV-DNA is higher than 1.0 × 10(3) U/ml in milk.</p>
