Objective To study the effects of the numbers of the canalith repositioning procedure on the treatment of benign paroxysmal positional vertigo(BPPV).Methods A clinical study was conducted on 68 BPPV patients using randomized controlled methods.The canalith repositioning procedure was performed on 34 patients in the treatment group only a day for 3 consecutive days,whereas it was performed on 34 patients in the control group once only,patients in both groups took betahistine mesylate tablets and flunarizine hydrochloride on the basis of ma-nipulative reduction.After one week and three months,the efficacy was evaluated,and the recovery situation was observed.ResuIts After 1 week of treatment,the cure rate was 82.4% in the treatment group,and 58.8% in the control group.The difference was statistically significant (P<0.05).After 3 months,the cure rate was 91.2% in the treatment group,and 85.3% in the control group,showing no significant difference (P>0.05 ).ConcIusion Based on the classifications of BPPV ,several times of manipulative reduction combined with drug treatment can im-prove short-term cure rates of BPPV and shorten healing time.

Objective To find the mutation of disease-causing genes of sudden unexplained death syn-drome (SU D S ) in the young by whole exome sequencing in one case. Methods O ne SU D S case was found no obvious fatal pathological changes after conventional autopsy and pathological examination. The whole exome sequencing was performed with the Ion Torrent PGMTM Systemwith hg19 as reference se-quence for sequencing data. The functions of mutations were analyzed by PhyloP, PolyPhen2 and SIFT. A three-step bioinformatics filtering procedure was carried out to identify possible significative single nu-cleotide variation (SN V ), which was missense mutation with allele frequency <1% of myocardial cell. Results Four rare suspicious pathogenic SN V were identified. C ombined with the analysis of convention-al autopsy and pathological examination, the mutation MYOM 2 (8_2054058_G/A ) was assessed as high-risk deleterious mutation by PolyPhen2 and SIFT, respectively. Conclusion Based on the second genera-tion sequencing technology, analysis of whole exome sequencing can be a newmethod for the death cause investigation of SU D S. The gene MYOM2 is a newcandidate SU D S pathogenic gene for mecha-nismresearch.

In view of the difficulties and blind spots of western medicine, how to make scientific decisions to standardize the treatment of breast cancer in traditional Chinese medicine and improve the participation of traditional Chinese medicine in the treatment of breast cancer is an important focus of innovative breakthroughs in breast cancer treatment. Based on the clinical experience of Professor LIN Yi, a master of traditional Chinese medicine, and on the basis of "disease identification and syndrome differentiation", this paper summarizes and refines the status of qi and blood imbalance, accumulation of phlegm and blood stasis, viscera deficiency, and cold heat cementation in breast cancer, and further proposes the "six views" of breast cancer balanced treatment: the pathogenesis view focuses on "evil invasion due to vital qi deficiency, and the proliferation of tumors", and the pathogenesis view focuses on "cancer toxin and imbalance of yin and yang", the diagnostic view focuses on "examining the underlying factors and understanding the causes and effects", the differentiation view focuses on "balancing qi, blood, yin, and yang to achieve harmony", the therapeutic view focuses on "supporting vital qi and eliminating evil, and considering the root cause and syndromes", and the rehabilitation view focuses on "adjusting balance to maintain a stable state". We are committed to holistic syndrome differentiation and treatment, balancing yin, yang, qi, and blood, thereby harmonizing the internal environment of the human body, and mobilizing the immune and rehabilitation functions of the body.

OBJECTIVETo analyze linkage disequilibrium of 12 short tandem repeat loci on chromosome X (X-STR) among an ethnic Han population from Guilin, Guangxi, and to study the genetic linkage and haplotype distributions of such loci in 2 linkage groups.

METHODS12 X-STR loci including DXS8378, DXS10159, DXS10162, DXS10164, DXS981, DXS6789, DXS7424, DXS101, DXS7133, GATA165B12, GATA31E08 and DXS7423 were genotyped using an AGCU X12 STR PCR Amplification kit. A total of 119 pedigrees were analyzed for linkage and linkage disequilibrium.

RESULTSTwo mutations were found at DXS7424, and 1 mutation was found at DXS10164. A total of 93 haplotypes of DXS10159-DXS10162-DXS10164 were constructed for 261 unrelated males and females, in addition with 167 haplotypes of DXS6789-DXS7424-DXS101-DXS7133. The values of recombination fraction between DXS10159 and DXS10162, DXS10162 and DXS10164, DXS6789 and DXS7424, and DXS7424 and DXS101 were 0.0269, 0.0236, 0.0505 and 0.0438, respectively.

CONCLUSIONLinkage disequilibrium of X-STR does not only depend on physical and genetic distances. There was incomplete linkage relationship between loci on DXS10159-DXS1016-DXS10164 and DXS6789-DXS7424-DXS101 linkage groups.
