Objective To investigate the clinical efficacy of a new-type moxibustion box in treating cervical spondylotic radiculopathy.Methods Sixty patients with cervical spondylotic radiculopathy were randomly allocated to treatment and control groups, 30 cases each. The treatment group received nape-eight-needle acupuncture plus new-type moxibustion box therapy and the control group, nape-eight-needle acupuncture plus conventional moxibustion box therapy. After 10 treatments, the NPQ score, the symptom and sign score and the VAS score were recorded in the two groups and the clinical therapeutic effects were compared between the two groups.Results The total effective rate was 100.0% in the treatment group versus 83.3% in the control group, and the difference was statistically significant (P<0.05). There were statistically significant pre-/post-treatment differences in the NPQ score, the symptom and sign score and the VAS score in the two groups (P<0.01,P<0.05). There were statistically significant post-treatment differences in the NPQ score, the symptom and sign score and the VAS score between the treatment and control groups (P<0.05).ConclusionNape-eight-needle acupuncture plus a new-type moxibustion box is an effective way to treat cervical spondylotic radiculopathy.

Mitochondria play a key role in cell metabolism. In addition to synthesizing ATP, they also participate in many physiological and pathological processes, including apoptosis, inflammation, oxidative stress, neuronal disease, tumor development, and aging. Most gene transcription of mitochondrial proteins occurs in the nucleus, so the biogenesis of mitochondria and the maintenance of mitochondrial homeostasis mainly depend on the expression of nuclear genes (nDNA) and mitochondria-nucleus interactions. Conversely, mitochondria can affect the expression of nuclear genes through nuclear transcription factors, a process called mitochondrial retrograde signaling. This review summarizes the research progress on mitochondria-nucleus retrograde signaling and its regulation, including the ways by which mitochondria regulate nuclear genes and affect biological processes, and discusses new strategies for the treatment of diseases that involve mitochondrial retrograde signaling in disease pathology.

Objective To observe the pronunciation characteristics of vowels' tone in prelingual hearing-impaired children accepted cochlear implant (CI). Methods 8 prelingual hearing-impaired children accepted CI aged 3~4 years (group CI) and 8 normal-hearing children (group NH) with the same age were asked to pronounce the vowels of /a/, /o/, /e/, /i/, /u/, and /ü/ in four tones with the direction of speech training teacher. The sounds were recorded and analyzed with Praat software extract Formants (F1, F2) and duration of the sounds. Results The error of vowels in four tones was more in group CI than in group NH, but difficult level was almost the same between groups. There was significant difference in the F1 of /e/, F2 of /i/ and /u/ in tone 2, F2 of /e/ and duration of /o/, /e/, and /ü/ in tone 3 between groups (P<0.05). Conclusion Pronouncing the four tones of vowels is more difficult for the hearing-impaired children. For vowels articulation training,it is important to focus on the mouth and breath training.

Objective To investigate the feature,pathological diagnosis and differential diagnosis of blastic plasmacytoid dendritic cell neoplasm (BPDCN).Methods The clinical and histological findings,immunophenotype,treatment and prognosis of one case with BPDCN were evaluated with review of the relevant literature.Results The female patient with age of 32 years presented as cutaneous lesions.Pathologic findings showed skin and bone marrow were involved.Microscopically,the tumors were composed of diffuse blasts with small to medium size,scant cytoplasm,highly irregular nuclear contours,dispersed nuclear chromatin and faint indistinct nucleolus.Immunohistochemical characteristics of the tumors were the positive expression of CD4,CD56 and CD123,and negative expression of CD3,CD20,CD34,TdT,MPO.Conclusion BPDCN is a rare and highly aggressive hematopoietic neoplasm.Except for the skin,bone marrow and lymph node can also be involved.The differential diagnosis is necessary from other haematopoietic and lymphoid tumors.

Objective To evaluate the expression and relationship of miR-100 and FZD-8, one of the major compo?nents of Wnt signaling pathway, and the correlation of their expressions with lymph node metastasis in patients with breast cancer. Methods The expression of miR-100 was determined in 50 samples of human breast cancer tissues and adjacent normal tissues by in situ hybridization. The correlation of miR-100 expression with lymph node metastasis was analyzed by Mann-Whitney U test. The expression of FZD-8 was measured in 50 samples of human breast cancer tissues and adjacent normal tissues by immunohistochemistry. The correlation of the miR-100 expression with the protein expression of FZD-8 was evaluated by Pearson rank analysis. Results The expression of miR-100 was significantly lower in human breast can?cer tissues than that in adjacent normal breast tissues [2.00 (1.00, 3.00) vs. 6.00 (3.50, 8.00)]. The miR-100 expression was lower in patients with lymph node metastasis than that in patients without lymph node metastasis [1.50 (1.00, 2.75) vs. 3.00 (2.00, 4.00)]. The expression of FZD-8 was significantly higher in human breast cancer tissues than that in adjacent normal breast tissues [8.00 (6.00, 9.00) vs. 6.00 (3.75, 9.00)]. The miR-100 expression was negatively correlated with the FZD-8 pro?tein expression in human breast cancer tissues (rs=-0.592, P<0.001). Conclusion The miR-100, as an anti-metastasis-miRNA, may involve in the metastasis of breast cancer, which may be related with the regulation of the expression of FZD-8.

Aim To investigate the role of mitochondrial aldehyde dehydrogenase 2 ( ALDH2) in the cardio-protection of ischemic postconditioning in isolated rat hearts. Methods Hearts isolated from male Sprague-Dawley rats were perfused on a langendorff apparatus and subjected to 30 min of regional ischemia( occlusion of left anterior descending artery) followed by 120 min reperfusion. Ischemic postconditioning was achieved by 6 cycles of 10 s reperfusion/10 s global ischemia starting at the beginning of reperfusion. The ventricular hemodynamic parameters and lactate dehydrogenase ( LDH) release during reperfusion were measured. The infarct size was measured by TTC staining method. The expressions of ALDH2,Bcl-2 and Bax at mRNA level of left anterior myocardium were detected by RT-PCR analysis. Results In contrast to ischemia and reperfusion,ischemic postconditioning improved the recovery of left ventricular developed pressure,rate pressure product during reperfusion,and reduced LDH release and infarct size. The expressions of ALDH2 mRNA level and the ratio of Bcl-2 /Bax were increased. Adminis-tration of ALDH2 antagonist cyanamide at the beginning of reperfusion attentuated the role of ischemic postconditioning. Conclusion Ischemic postconditioning plays a role in the cardioprotection partially through increasing mitochondrial ALDH2 mRNA expression.

Objective To construct single chain antibody specific to membrane protein of Schistosoma japonicum by gonetic engineering technique. Methods The V\-H (heavy-chain variable region) and V\-L (light-chain variable region) genes were amplified by PCR from the genomic DNA of NP11-4 cell line, and sequenced by Sanger's method. The ScFv was constructed in pTHA90 vector using V\-H and V\-L genes, then expressed by IPTG. Results The V\-H and V\-L genes were obtained through PCR. The DNA sequences showed that V\-H and V\-L were new variable region genes of antibody. They were registered by GenBank. A ScFv gene with (Gly4Ser) 3 intralinker in the pTHA90 vector was successfully constructed. The ScFv was expressed as thioredoxin-fused proteins about 36\^2 kDa. Conclusion A specific ScFv against the membrane protein of Schistosoma japonicum was constructed and expressed.
