In order to develop safe training intensity and training methods for the passive balance rehabilitation train- ing system, we propose in this paper a mathematical model for human standing balance adjustment based on T-S fuzzy identification method. This model takes the acceleration of a multidimensional motion platform as its inputs, and human joint angles as its outputs. We used the artificial bee colony optimization algorithm to improve fuzzy C--means clustering algorithm, which enhanced the efficiency of the identification for antecedent parameters. Through some experiments, the data of 9 testees were collected, which were used for model training and model results validation. With the mean square error and cross-correlation between the simulation data and measured data, we concluded that the model was accurate and reasonable.

BACKGROUND: Long noncoding RNAs play a role In transcription and post-transcrlptlonal levels, participate in the regulation of bone regeneration, and are closely related to osteoarthritis as well.  OBJECTIVE: To review the research progress of long noncoding RNAs in bone regeneration and osteoarthritis. METHODS: A computer-based search of CNKI, PubMed, and Elsevier was performed for relevant articles regarding long noncoding RNAs in bone regeneration and osteoarthritis published from January 2000 to June 2019, including review, basic research and clinical research. The search terms were “LncRNA; bone; bone regeneration; osteoarthritis” in Chinese and English. After preliminarily reading titles and abstracts, irrelevant articles were excluded. According to the inclusion and exclusion criteria, 64 articles were finally included in result analysis. RESULTS AND CONCLUSION: Bone regeneration is a complex process involving the interaction of osteoblasts and osteoclasts. Long noncoding RNAs are involved in the differentiation of osteoblasts and the production of osteoclasts, which play an important role in the balance of osteoblasts and osteoclasts. Therefore, it is a key molecule of bone regeneration. Long noncoding RNAs are involved in the occurrence and development of osteoarthritis and differentially expressed in osteoarthritis patients and healthy people, some of which are elevated and some are decreased in osteoarthritis patients. Thus, defining their respective expression differences and functions is of great significance for the prevention and treatment of osteoarthritis.

OBJECTIVETo study the clinical effect of the Gartland III humerus supracondylar fractures in children by manipulative reduction and Kirschner wire percataneous internal fixation.

METHODSFrom July 2010 and July 2013, 60 patients with Gartland III humerus supracondylar fracture were selected and divided into treatment group and control group. In the treatment group 32 patients were treated with traditional bone setting tetradeca-manipulative reduction and percataneous Kirschner wire internal fixation,included 18 males and 14 females with an average age of (7.8 +/- 2.7) years old ranging from 5 to 11; in the control group 28 patients were treated with open reduction and Kirschner wire internal fixation,included 16 males and 12 females with an average age of (7.2 +/- 3.0) years old ranging from 4 to 12. The motion range of the elbow joint,the time of fracture clinical healing, and the effect after 6 months of Flynm clinical functional assessment standards were observed and compared.

RESULTSThe average fracture healing time of the control group (5.01 +/- 0.43) weeks was longer than that of the treatment group (4.29 +/- 0.29) weeks (t = 7.49, P = 0.00). At 6 months after treatment,the elbow motion range of the treatment group (146.02 +/- 2.28) was more than that of the control group (140.76 +/- 4.42) (t = -5.67, P = 0.00). At 6 months after treatment, according to Flynn evaluation, in the control group,there were 7 cases as excellent, 16 as good, 4 fair, 1 poor; in the treatment group, excellent in 21, good in 9, fair in 2 (U = 3.09, P = 0.002).

CONCLUSIONManipulative reduction and Kirschner wire percataneous internal fixation for treatment of children's Gartland III humerus condyle fractures can shorten fracture clinical healing time and the clinical curative effect is better.

The standard treatment for colorectal cancer still have not been unified,especially the treatment for patients with locally advanced rectal cancer (T3 or T4 stage) is controversial,and multidisciplinary comprehensive treatment is recommended by most of the scholars.Precise preoperative diagnosis and staging for locally advanced rectal cancer is very important.Currently,transrectal ultrasound (TRUS),multi-slice spiral computed tomography,magnetic resonance imaging (MRI) are playing important roles in the preoperative diagnosis and staging,while controversies on the efficacies of different imaging diagnosis on the evaluation of rectal cancer exist between domestic and overseas scholars.From October 2010 to October 2012,the imaging data of 30 patients with locally advanced rectal cancer who were admitted to the Tumor Hospital of Yunnan Province were retrospectively analyzed.The results showed that TRUS,computed tumography and MRI had guidance value in preoperative tumor staging and evaluation of neoadjuvant therapy for patients with locally advanced rectal cancer,which provide a more reliable basis for the selection of appropriate treatment programs.

Objective:Mutation in the gap junction beta 6 (GJB6) gene has been reported to be associated with an autosomal dominant disorder hidrotic ectodermal dysplasia (HED), characterized by congenital nail clubbing, alopecia and palmoplantar keratoderma. The aim of this study is to investigate relationship between genetic mutation in GJB6 and HED in an affected Chinese family.
Methods:We selected a Chinese HED family consisting of a total of 17 individuals including 8 HED patients (5 males and 3 females). The whole coding region of GJB6 was amplified by polymerase chain reaction and sequenced.
Results:Sequence analysis identified a heterozygous missense mutation c.31G>A (p.G11R) in GJB6 gene of affected individuals, but not in healthy individuals.
Conclusion:A c.31G>A (p.G11R) missense mutation in GJB6 gene is the genotypic characteristic for HED in Chinese population.

Objective To explore the dynamic changes and clinical significance of relative pituitary hormones in children after craniocerebral injury.Methods The quantitative analysis and dynamic observation were performed in 125 children after craniocerebral injury and 20 voluntary healthy children of relative pituitary hormones including serum prolactin(PRL),cortisol(PTC),three free triiodothyronine (FT3),free thyroxine (FT4),thyroid stimulating hormone (TSH),growth hormone (GH) by applying electrochemical luminescence method.Tbe hormone variational characteristics were analyzed according to posttraumatic time,Glasgow Coma Scale(GCS) scores on admission and Glasgow Outcome Scale (GOS) scores on discharge,and the relationship between hormone variational characteristics of 58 cases was followed up over 2 years and the activities of daily living (ADL) were also investigated.Results The serum PRL was significantly increased on the first,third and fifth day compared with the healthy control group (P =0.000 0,0.000 0,0.006 7),respectively.There was significant difference between mild,moderate and severe groups within 30 days after suffering from craniocerebral injury (P ＜ 0.05).PTC was heavily increased within 3 days,and significant difference existed among mild and moderate groups mild and severe groups (all P ＜ 0.05) ; TSH,FT3,FT4 decreased slightly after injury and gradually rose in later;GH change wasn't significant;and the larger variation of relative pituitary hormones was responsible for lower GCS scores;FT3,FT4,TSH,and GH decreased in different degrees,which were found in parts of children with craniocerebral injury,and the significant difference of serum PRL existed between GOS scores 4-5 and GOS scores 1-3 groups (P =0.000 1).Conclusions The changes of relative pituitary hormones were associated with the posttraumatic time and the severity of craniocerebral injury.The PRL in serum can aid in prediction of outcome for the children with craniocerebral injury.

Objective To investigate changes of relative pituitary hormones in adults with traumatic brain injury (TBI) and the related clinical significance.Methods Quantitative analysis and dynamic observation of relative pituitary hormones were performed in 158 TBI patients by electrochemical luminescence method.Measured indices included plasma total cortisol (PTC),free triiodothyronine (lT3),free thyroxine (FT4),thyrotropin (TSH),growth hormone,follicle stimulating hormone (FSH),luteinizing hormone (LH),estradiol,testosterone,and prolactin.Results Prolactin and PTC increased in the acute phase,but gradually reduced three days after trauma.TSH,FT3,and FT4 slightly decreased after trauma,followed by a gradual return.While there were no significant changes in FSH,LH,estradiol,testosterone,and growth hormone after trauma.Changes in relative pituitary hormones were more profound in patients with a lower GCS.Some patients presented different degree of reduced hormones in recovery period and needed hormone replacement therapy.Among the patients with poor activity of daily living (ADL),lvothyroxine replacement therapy was applied in 2 patients (2/6),prednisone acetate in 1 (1/6),and eleven acid testosterone in 2 (2/6).Among patients with mild ADL,levothyroxine replacement therapy was applied in 2 patients (11％),prednisone acetate in 1 (6％),and eleven acid testosterone in 3 (17％).Among patients with good ADL,levothyroxine replacement therapy was applied in 2 patients (4％) and eleven acid testosterone in 3 (6％).Persistent prolactin elevation was found in patients with poor outcome.Conclusions Changes of relative pituitary hormones in adult patients with TBI are associated with severity and duration of trauma.Abnormal prolactin level can affect outcome of the patients.
