Objective:This study aims to analyze the differences in the alternative splicing pattern of ADAR2 among glioma cell lines U87, U251, A172, and normal human astrocyte HA1800. Methods:A-to-I editing level at the Q/R-Site of GluR-2 was analyzed by RT-PCR and sequencing. Real-time PCR was performed to detect the expression level of each alternatively splicing variant using a specific primer that was confirmed to amplify only the targeted template and not other alternatively spliced variant fragments. Results:We verified that the Q/R-Site of GluR-2 is under-edited in glioma cell lines. Real-time PCR revealed that the ADAR2 pre-mRNA splic-ing pattern has no significant difference at exons 1a and 2 between glioma cell lines and normal human astrocyte. We also detected that the amount of alternative splicing variants, including exon 5a, was higher than that of alternative splicing variants not including exon 5a in human glioma cell lines. However, the expression of alternative splicing variants, including exon 5a, was lower than that of alterna-tive splicing variants not including exon 5a in human astrocyte. Conclusion:Evident differences in splicing were observed at the site of exon 5a between glioma cell lines and normal human astrocytes. The difference in the alternatively splicing pattern at exon 5a may be attributed to the decreased activity of ADAR2.

·Diabetic Retinopathy ( DR ) has gradually worsening and lingering, which is the leading cause of global young people blindness. With the progression of the disease, patients with diabetes mellitus ( DM) will have different degrees of DR. If you can not prevent and give acute early intervention, once the visual acuity decreased significantly, DR would be difficult to reverse. DR progressively has worsening, the treatment status has no optimistic. Therefore, DR in the early prevention and treatment will be indispensable. This article summarizes some of the early warning of the occurrence and development of biological markers and characteristic indicators in order to provide a basis for the early prevention of DR.

ObjectiveTo observe the efficacy of wrist-ankle acupuncture plus auricular point sticking in treating pre-exam anxiety syndrome.MethodSixty patients with pre-exam anxiety syndrome were randomized into a treatment group to receive wrist-ankle acupuncture plus auricular point sticking (30 cases, 11 cases dropped out) and a control group to receive auricular point sticking (30 cases, 1 dropped out). In the treatment group, the bilateral Upper 1 zones were punctured regarding the wrist-ankle acupuncture, and for the auricular point sticking, Heart (CO 15), ear Shenmen (TF 4), Endocrine (CO 18), Adrenal Gland (TG 2p), Subcortex (AT 4) were selected. In the controlgroup, the same auricular points were treated. For both groups, the intervention began from 1 week prior to the exam, 3 d as a treatment course, and the therapeutic efficacy was evaluated after 2 successive courses. The Sarason Test Anxiety Scale (TAS) and autonomic function test were used to assess the anxiety severity before and after treatment. ResultThe total effective rate was 84.2% (16/19) in the treatment group versus 82.8% (24/29) in the control group, and the difference was statistically insignificant (P>0.05). The TAS score dropped significantly in the control group after intervention (P<0.01).ConclusionWrist-ankle acupuncture plus auricular point sticking and auricular point sticking alone both can effectively improve the symptoms of pre-exam anxietysyndrome.

Ochronosis is a musculoskeletal manifestation of alkaptonuria, a rare hereditary metabolic disorder occurs due to the absence of homogentisic acid oxidase and leading to various systemic abnormalities related to deposition of homogentisic acid pigmentation (ochronotic pigmentation). The present case reports the clinical features, radiographic findings, treatments and results of a cervical spondylotic myelopathy woman patient due to the ochronotic arthropathy of the cervical spine. The patient aged 62 years was presented with gait disturbance and hand clumsiness. Physical examination, X-rays, computed tomography and lab results of the urine sample confirmed the presence of ochronosis with the involvement of the cervical spine. The patient underwent a modified cervical laminoplasty due to multi-segment spinal cord compression. The postoperative follow-up showed a good functional outcome with patient satisfaction. The present study concludes the conditions and important diagnostic and surgical aspects of a patient. It is necessary to identify the condition clinically and if cord compression is observed, appropriate surgical interventions needs to be instituted.

Objective:To observe the effect of warm-unblocking acupuncture plus fluticasone propionate nasal spray on the pulmonary ventilation, level of interferon-γ (IFN-γ) and sleep quality in patients with allergic rhinitis (AR). Methods: A total of 112 AR patients were enrolled between January 2013 and August 2018 and were divided into an observation group and a control group by the random number table method, with 56 cases in each group. Patients in the observation group received warm-unblocking acupuncture plus fluticasone propionate nasal spray, and patients in the control group only received fluticasone propionate nasal spray. The nasal symptom score, pulmonary function indexes, the levels of IFN-γ and interleukin (IL)-4 in serum, and sleep quality in the two groups were compared. Results: After treatment, the total effective rate in the observation group was higher than that in the control group (P<0.05). The nasal symptom score dropped in both groups after treatment (both P<0.05), and the score in the observation group was lower than that in the control group (P<0.05). The pulmonary ventilation indexes all increased significantly after treatment in the observation group (all P<0.05); the forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) ratio (FEV1/FVC) and the forced expiratory flow at 50%, 75% and 25%-75% of the vital capacity (FEF50%, FEF75%, FEF25%-75%) increased after treatment in the control group (all P<0.05); the pulmonary ventilation indexes were higher in the observation group than those in the control group (all P<0.05). The level of IFN-γ increased significantly after treatment in the two groups (both P<0.05) and the level of IL-4 dropped significantly (both P<0.05); the observation group had a higher IFN-γ level (P<0.05) and a lower IL-4 level (P<0.05) compared with the control group. Regarding the Pittsburgh sleep quality index (PSQI), the scores of subjective sleep quality, habitual sleep efficiency and sleep disturbances and the general PSQI score decreased significantly after treatment in both groups (all P<0.05), and the scores in the observation group were significantly lower than those in the control group (all P<0.05). Conclusion: Warm-unblocking acupuncture plus fluticasone propionate nasal spray can effectively control the clinical symptoms and improve pulmonary function in the treatment of AR; this approach can regulate the levels of IFN-γ and IL-4 towards the normal range in AR patients; it can also improve patient’s sleep quality. This method can produce more significant efficacy than fluticasone propionate nasal spray used alone.

Objective To study the differentiation and proliferation ability of the spinal neural stem cells (NSCs) at different gestational ages in fetal rats. Methods Sprague-Dawley fetal rats were divided into group A (12 days of pregnancy), group B (14 days of pregnancy) and group C (16 days of pregnancy). NSCs were separated with enzyme-assisted microdissection. The diameter and numbers of NSCs balls were measured at different time. The cell growth curve was drawn with CCK8 colorimeter. NSCs were identified with BrdU/Nestin immunohistochemical staining. They were induced with 10% fetal bovine serum for 10 days, and the expression of β-tubulinⅢ and glial fibrillary acidic protein was detected with immunocytochemistry. Results There were cells expressed BrdU, Nestin, β-tubulinⅢ and GFAP in all the group. The most cells (22.74±0.79%) expressed β-tubulinⅢ in the group B, but no significant difference between group B and group C. The cell vitality on the 5th day of third-generation neural stem cells was the most in group B. Conclusion For enzyme-assisted microdissection, it may obtain more neurons to isolate the neural stem cells from 14 days of pregnancy pregnant rats.

OBJECTIVETo investigate the proliferation-inhibiting and multidrug-resistant reversing effect of bortezomib on human HL-60 cells, and to explore the mechanism of bortezomib-induced proliferation inhibition in human leukemia cells.
METHODSThe multidrug resistant leukemia cell lines HL-60/DNR and HL-60/VCR cells were used as models, and sensitive HL-60 cells as a control. The cytotoxicity of bortezomib on HL-60, HL-60/DNR, HL-60/VCR cells were measured by MTT method, and the non-cytotoxicity dose was determined as reversible dose. The cells were divided into 4 experimental groups: HL-60/DNR + DNR, HL-60/DNR + DNR + bortezomib, HL-60/VCR + VCR, HL-60/VCR + VCR + bortezomib. The bortezomib resistant reversal fold was calculated. The levels of XIAP, cIAP-1, and cIAP-2 mRNA and proteins expression and the activation of NF-κB of the HL-60/DNR, HL-60/VCR cells were examined by quantitative real time RT-PCR and western blot respectively after treated with gradually increasing concentrations of bortezomib (10, 40, 80 nmol/L) for 48 hours.
RESULTSBortezomib inhibited the cell growth of HL-60, HL-60/DNR, and HL-60/VCR in a concentration-dependent manner. The IC(50) values were (28.90 ± 3.99), (81.19 ± 9.34), and (73.48 ± 8.94) nmol/L, respectively. After treated with 10nmol/L bortezomib for 48 hours, the IC(50) value of DNR to HL-60/DNR decreased from (12.90 ± 1.75) µmol/L to (3.54 ± 0.57) µmol/L (P < 0.01), and that of VCR to HL-60/VCR from (33.25 ± 7.28) µmol/L to (9.97 ± 1.15) µmol/L (P < 0.01). The reversal fold (RF) values were 3.32 ± 0.53 and 2.64 ± 0.28, respectively. Bortezomib down-regulated the levels of XIAP, cIAP-1, and cIAP-2 mRNA and protein expression and inhibited the NF-κB activation in a concentration-dependent manner.
CONCLUSIONBortezomib can inhibit the proliferation of HL-60 cells and reverse multidrug-resistance in the cells. The possible mechanism is associated with down-regulation of IAPs expression.
