OBJECTIVE: To observe the efficacy of "Buqi Yixue "needling on clinical symptoms, neurological function and nerve conduction velocity in patients with diabetic peripheral neuropathy. METHODS: Eighty-six patients with diabetic peripheral neuropathy numbness and pain were equally randomized into control group and treatment group. The patients of the control group received basic treatment and oral administration of Cilostazol (50 mg/time, 2 times/d) and Epalrestat (50 mg/time, 3 times/d). The patients of the treatment group received acupuncture stimulation of Danzhong (CV17), Qihai (CV6), Pishu (BL20), Quchi (LI11), etc., for 30 min, once every day, on the basic treatment. The treatment was conducted for 8 successive weeks. The scores of Traditional Chinese Medicine (TCM) symptoms, Toronto clinical scoring system (TCSS) and nerve conduction velocity (NCV) were detected before and after the treatment. RESULTS: After the treatment, the scores of TCM symptoms and TCSS were considerably decreased (P<0.05), and the NCV was significantly increased (P<0.05) in both groups compared with those of their own pre-treatment. The the-rapeutic effect of the treatment group was significantly superior to that of the control group in lowering the scores of TCM symptoms and TCSS, and in up-regulating the NCV (P<0.01). CONCLUSION: "Buqi Yixue" needling is effective in improving clinical symptoms and increasing NCV in patients with diabetic peripheral neuropathy.

Objective To analyze the frequency of mixed lineage leukemia (MLL) gene rearrangement,the frequent types of fusion genes and clinical characteristics of childhood acute leukemia (AL) with MLL gene rearrangement.Methods Morphological and molecular characteristics of 87 AL patients with MLL gene rearrangement were studied and analyzed.MLL fusion gene was detected by way of reverse transcription polymerase chain reaction (RTPCR).Results Eighty-seven cases with MLL gene rearrangement were found in 1209 AL patients with incidence of 6.41％ and 9.36％ respectively in ALL and in acute myelocytic leukemia (AML) respectively.Fifty-eight cases of ALL were all B-ALL,28 cases of AML included 17 cases of M5,5 cases of M4,4 cases of M2,1 case of M3 and 1 case of M6.While there was 1 case of mixed of lineage leukemia and myeloid and T-lymphoblastic antigen presentation.The clonal chromosomal aberration was detected in 45 out of 76 cases (59.21％),and chromosome 11q23 aberration were observed in 28 cases (36.84％).There were 7 different kinds of fusion genes,including MLL-AF9 in 25 cases,dupMLL in 25 cases,MLL-AF4 in 17 cases,MLL-AF10 in 9 cases,MLL-ENL in 8 cases,MLL-AFlq in 2 cases,and MLL-AF6 in 1 case.Among the cases of MLL-AF4,MLL-AF9,MLL-AF10,MLL-ENL and dupMLL,there were statistical differences in lineage,age and initial white blood cell count (WBC) (all P ＜ 0.05).Conclusions In childhood AL with MLL gene rearrangement,B-ALL is more common in ALL,whereas M5 and M4 are more common in AML.The common types of fusion genes are dupMLL,MLL-AF9 and MLL-AF4.Patients with the different kinds of MLL fusion gene may present different clinical characteristics.The most common ALL cases are those with MLL/AF4 and MLL/ENL who may be younger with higher WBC than the others.

OBJECTIVETo identify the gene mutation for two Chinese families with autosomal dominant non-syndromic hearing impairment(NSHI).

METHODSTwo NSHI pedigrees with common ancestor were identified by clinical examination and family investigation. Linkage analysis was performed for all known NSHI loci, and all exons and exon-intron boundaries of the non-muscle myosin heavy chain 14 (MYH14) gene were amplified by PCR and sequenced.

RESULTSThe disease-causing gene of these 2 pedigrees was fine mapped to the DFNA4 locus on 19q13.33. A heterozygous transition of c. 359T>C (p.S120L) in MYH14 gene was identified. The mutation was detected in all patients but not in normal members in the two families.

CONCLUSIONIt is the first report that mutation in MYH14 gene can cause dominant non-syndromic hearing impairment in Asian population, suggesting that MYH14 gene can be a disease-causing gene of Chinese patients with hearing impairment.

Objective: To evaluate the plaque distribution on the fitting surface of fixed implant prostheses which were supported by multi-unit abutment. Methods : 21 patients with maxillary full-arch implant-supported fixed prostheses were collected. Plaque accumulation at the fitting surfaces were evaluated 3 months after restoration, by analyzing the digital photographs recorded by Imag e J 2.1.4.7. Results: The average percentage of area covered with plaque was (46.13 ± 7.23)%. Plaque accumulation on the buccal and palatal area were (41.53 ± 3.08) and (53.76 ± 3.07)% respec⁃ tively, with a significant difference (t = 16.750, P < 0.001). The free area (71.86 ± 2.00) % was significantly higher than the anterior area (48.85 ± 2.09)% (t = 40.445, P < 0.001), andalso the middle area (49.33 ± 0.98)% (t = 47.124 , P < 0.001). The plaque percentage was higher when the distance between the implants was shorter. Conclusion To Minimize the palatal extension and free area of the prostheses, and to maximize the distances between the implants, were helpful to improve the oral hygiene control. It might be the key to keep a good outcome of the maxillary full-arch implant-supported fixed prostheses.

Objective:To investigate the differential expression and gene functions of up-regulated genes in rats with spinal cord injury. Methods:Female Sprague-Dawley rats' model of spinal cord injury was established with the modified Allen's method. Gene chip technology was used to detect the variation of differentially expressed genes in the spinal cord after spinal cord injury in rats. The differences in genes, functional localization and pathways were analyzed with gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway database. Results:The results of total RNA quality in spinal cord segment were qualified. Gene chip results showed that there were 1874 differentially up-regulated genes and 2348 differentially down-regulated genes. Bioinformatics was used to analyze differentially up-regulated genes in terms of biological processes, cellular components, and molecular functions. The differentially up-regulated genes were involving apoptosis, immune response, inflammation, etc., pathway analysis mainly showed the differentially up-regulated genes involved phosphoinositide 3-kinase protein kinase B signaling pathway and Toll-like receptor signaling pathways. Conclusion:Differentially up-regulated genes may be involved in secondary reactions following spinal cord injury, such as inflammation, immune response and hypoxia, and then further affect motor function and sensory function.

Objective: To evaluate the safety and effectiveness of a vaccine based on latent membrane protein 2 (LMP2) modified dendritic cells (DCs) that boosts specific responses of cytotoxic T lymphocytes (CTLs) to LMP2 before and after intradermal injection in patients with nasopharyngeal carcinoma (NPC). Methods: DCs were derived from peripheral blood monocytes of patients with NPC. We prepared LMP2-DCs infected by recombinant adenovirus vector expressing LMP2 (rAd-LMP2). NPC patients were immunized with 2 × 10 Results: We demonstrated that DCs derived from monocytes displayed typical DC morphologies; the expression of LMP2 in the LMP2-DCs vaccine was confirmed by immunocytochemical assay. Twenty-nine patients with NPC were enrolled in this clinical trial. The LMP2-DCs vaccine was well tolerated in all of the patients. Boosted responses to LMP2 peptide sub-pools were observed in 18 of the 29 patients with NPC. The follow-up data of 29 immunized patients from April, 2010 to April 2015 indicated a five-year survival rate of 94.4% in responders and 45.5% in non-responders. Conclusion In this pilot study, we demonstrated that the LMP2-DCs vaccine is safe and effective in patients with NPC. Specific CTLs responses to LMP2 play a certain role in controlling and preventing the recurrence and metastasis of NPC, which warrants further clinical testing.

Malocclusion is one of the three most common oral diseases reported by World Health Organization(WHO). In China, its incidence rate is rising. Malocclusion seriously affects the dental and maxillofacial function, facial appearance and growth development of nearly 260 million children in China, and what is more, it affects their physical and mental health development. Malocclusion occurrence is related to genetic and environmental factors. Early treatment of malocclusion can create a good dental and maxillofacial development environment, correct abnormal growth and control the adverse effects of abnormal genetic factors. It can effectively reduce the prevalence of children's malocclusion and enhance their physical and mental health. This is an urgent need from the economic perspective of our society, so it has great practical and social significance. Experts from the project group "standard diagnose and treatment protocols for early orthodontic intervention of malocclusions of children" which initiated by China National Health Institute of Hospital Administration wrote the "China Experts' Consensus on Preventive and Interceptive Orthodontic Treatments of Malocclusions of Children", which aims to guide and popularize the clinical practice, improve the clinical theory and practice level, and accelerate the disciplinary development of early treatment of children's malocclusion in China. The consensus elaborates the harmfulness of malocclusion and the necessity of early treatment, and brings up the principles and fundamental contents. Based on the law of dental and maxillofacial development, this paper puts forward the guiding suggestions of preventive and interceptive treatments in different stages of dental development ranging from fetus to early permanent dentition. It is a systematic project to promote and standardize the early treatment of malocclusion. Through scientific and comprehensive stratified clinical practice and professional training, the clinical system of early treatment of malocclusion in China will eventually be perfected, so as to comprehensively care for children's dental and maxillofacial health, and improve their oral and physical health in China.
