Objective To explore the preventive effect of the supplemental dietary boron on bone damage of rats with excess fluoride (EF) ingestion. Methods Twenty-four Sprague-Dawley rats aged 4-5 weeks old were divided into the control (C group, treated with distilled water and the elementary dietary), the excessive fluoride dose group (EF group, treated with distilled water with 100mg/L F-from 221.0g NaF per liter and the elementary dietary) and the boron prevention group (P group, treated with 100mg/L F-distilled water and the supplemental boron dietary). Three months after the experiment, fluorine, boron contents and AKP activities in serum, total RNA and fluorine contents in bone, vertical and transverse diameter and dry weight of tibias of rats were assayed, and bone biomechanics of femur and bone mineral density (BMD) were determined. Results Compared with those in the C group, fluorine contents in serum and bone, AKP activities in serum of rats in the EF group significantly increased; total RNA in bone and BMD of the bone of whole body and tibia decreased, vertical and transverse diameter of tibias was shortened, dry weight was decreased; peak load of femur increased but maximum deformation decreased. Compared with those in EF group, fluorine contents in serum and bone, AKP activities in serum of rats in the P group obviously decreased; total RNA in bone and BMD of whole body, lumbar vertebrae and tibias notably increased, vertical and transverse diameters and dry weight of tibia were enhanced, peak load of femur was obviously raised. Boron contents in serums of rats in three groups had no significant differences. Conclusion Bone damage obviously occurred in rats with EF intake, and the supplemental dietary boron had a preventive effect on these changes.

Objective To investigate the health-related quality of life(HRQOL)of the recovered patients with depression and its influential factors.Methods From March 2008 to April 2009,150 depressive patients andergoing the following up treatment were recruited,and finally 124 patients rocovered,and quality of life for patients recovered were compared to published norms for the general Chinese people.The general demography material seale.Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),personality traits(Eysenck personality Inventory-EQP)the short form 36 item(SF-36)questionnaire and social support scale(SSS)were applied to an subjects.The SPSS 13.0 software for data processing,the group t test and the multiple linear regression analysis was adopted.Results ①The average score of seven domains of quality of life(RP,BP,GH,VT,SF,RE,MH )for the recovered patients were better than that of the pre-treatment patients(P<0.01),except the PF(89.23±14.09,87.23±16.81,t=1.044,P>0.05).But the average score of seven domains of quality of life for the re-covered patients were worse than that of the healthy people(P<0.01),except the PF(89.23±14.09,89.01±15.73,t=1.266,P>0.05).②The quality of life 0f the recovered patients remarkably related with the anxiety level, neuroticism, extraversion, recurrent depression,economic condition and social support(P<0. 01) . Conclusion The recovered depressive patient s health-related quality of life were improved significantly afer treatment, what were influenced by neuroticism,extraversion,anxiety as a trait,recurrent depression,economic condition and social support.Above mentioned factors should be taken into account when rehabilitation.

Objective To investigate the metabolite changes in the preschool children with autism spectrum disorder (ASD) using MR spectroscopy (MRS) and explore the associations between image findings and clinical variables, which may provide a noninvasive brain biochemical method for the early diagnosis and prevention of autism. Methods Twenty one cases of preschool ASD children (3-6 years old) and age-and sex-matched 20 preschool healthy controls underwent single voxel short (SVS) short TE (TE=30 ms) MRS. The absolute metabolite concentrations in the anterior cingulate cortex (ACC) , anterior middle anterior cingulate cortex (aMCC) and posterior cingulate (PCC) were quantitatively analyzed using LCModel software. Two independent sample t tests were used for analysis. The relationships between metabolite concentrations and diagnostic and statistical manual of mental disorders (DSM-IV) , childhood autism rating scale (CARS) and autism behavior checklist (ABC) were analyzed by Pearson correlation analysis. Results Compared to control subjects, ASD patients had significantly lower N-acetylaspartate (NAA) values (4.35 ± 0.80, 6.34±0.82, 8.04±0.97 mmol/L respectively) in ACC, aMCC and PCC (t=2.640, P=0.012;t=2.182, P=0.035;t=3.343, P=0.002) , had significantly lower choline (Cho) 1.32±0.22 mmol/L (t=2.905, P=0.006) and glutamine and glutamate complex (Glx) 10.02 ± 0.88 mmol/L (t=2.090, P=0.043) in PCC. Cho, total creatine (tCr) , myo-Inositol (MI) and Glx levels did not differ between groups in other aforementioned regions (P>0.05). Negative correlations between the NAA ualues in the PCC and CARS (r=-0.504, P=0.020) were detected, and no significant correlation among DSM-IV, CARS, ABC and other metabolite values (P>0.05). Condnsions The biochemical changes in the preschool children with ASD in cingulate reflect the neuronal loss, structural or functional damage and cell membrane enzyme metabolic dysfunctions, may reveal the pathological basis of ASD. These results may provide noninvasive and quantitative methods for the diagnosis and prognosis evaluation of ASD child.

Objective? To expLore the status quo of cLinicaL traditionaL Chinese medicine (TCM) nursing training between 2007 and 2017, and to provide a reference and guidance for further standardizing TCM nursing training and conducting reLevant research. Methods? The articLes reLated to TCM nursing training which were pubLished between 2007 and 2017 were retrieved from CNKI, CBM and VIP databases and anaLyzed using bibLiometric methods. ResuLts? TotaLLy 109 vaLid articLes were found, and the number of articLes pubLished over the past ten years tended to increase; the articLes were pubLished on 54 journaLs in which those incLuded in Chinese core journaLs of Peking University accounted for 1.8%; most of the first authors were from Guangdong, Zhejiang and Jiangsu provinces; the research mainLy focused on the appLication of various training methods in TCM nursing training and the discussion of TCM nursing skiLLs; the degree of cooperative authorship was 2.7 persons, and the funding rate was 32.1%; junior and intermediate nurses accounted for 61.9% of the training subjects, and there were a few senior and speciaLized nurses, with community nurses accounting for onLy 3.7%;and the top 5 evaLuation indicators were theoreticaL performance, operationaL performance, nurse's satisfaction, patient's satisfaction and quaLity of nursing. ConcLusions? TCM nursing has become increasingLy important, but the quaLity of reLevant research is Low. There is no in-depth and extensive research in this regard, nor standardized study design and training modeL. Few studies have used mobiLe information pLatforms, and the evaLuation indicators are not objective or uniform.

OBJECTIVETo observe clinical efficacy of intra-articular injection of Sodium hyaluronate (SH) accompanied with external application of Sanhua ointment (SHO) for knee osteoarthritis.

METHODSOne hundred and twelve patients with osteoarthritis were randomly divided into two groups, Group I was treated with SH and Group II was treated with SH plus SHO. The entire condition of knee joint in the two groups were compared before and after treatment according to Lysholm's function scoring.

RESULTSThe functional score in the two groups at the 2nd week, 5th week, 3rd month and end of 1st year of the treatment course were significantly higher than that before treatment (P < 0.05), and the scores continuously increased within the first 3 months of treatment. Comparison of scores between the two groups showed that scores in Group II was significantly higher than those in Group I at the corresponding period. The total effective rate after 1 year treatment in Group lI was higher than that in Group II (81.5% vs 96.6%, P < 0.05). In Group II , the initial time of symptom improving was earlier and the adverse effect disappeared more quickly than those in Group I markedly.

CONCLUSIONThe efficacy of combined therapy of intra-articular injection of SH and SHO for knee osteoarthritis was superior to that of intra-articular injection of SH only.

Osteosarcoma is a kind of primary malignant tumor of bone originated from mesenchymal tissue, which mainly occurs in children and adolescents, and presents the characteristics of high malignancy, rapid growth, early metastasis and poor prognosis. Currently, most of the studies at home and abroad mainly focused on therapeutic procedures. However, reliable prediction indices or evaluation systems are also pivotal for monitoring disease change, guiding treatment and evaluating prognosis. Multiple clinical predictors have been reported to be related to the prognosis of osteosarcoma, which can be roughly divided into 9 categories according to their characteristics. Each kind of predictor owns its inherent advantage and disadvantage, and full understanding of them and their characteristics can be helpful to improve the prognosis of osteosarcoma.

Objective: This study aimed to investigate the clinicopathological characteristics and prognosis of adult rhabdomyosarcoma (RMS) patients. Methods: The clinical data of 34 adult RMS patients were retrospectively analyzed. Based on their intervention and treatment, patients were divided into operation group (n=7), chemotherapy group (n=8) and operation plus chemotherapy group (n=19). The clinical characteristics and treatment outcomes of the three groups were compared. Results: A statically significant difference was found in IRSG surgical-pathological stage among the three groups (P=0.026), while no significant difference existed in gender, age of disease onset, primary site, tumor size, pathological subtypes and IRSG risk group in the three groups (all P>0.05). In the operation group, three CR, one PR, one SD and two PD were achieved and one CR, one PR, one SD and five PD were obtained in the chemotherapy group. While in the chemotherapy plus operation group, four CR, twelve PR, one SD and two PD were achieved. A significant difference was found in response (P=0.043) and median overall survival (OS) (P=0.036) among the three groups, which were 44.7, 26.9 and 53.6 months, respectively. Conclusions Pleomorphic RMS was the main histological subtype for adult RMS patients, and the prognosis for adult RMS was usually poorer than that for pediatric RMS patients. Single therapeutic approach could not achieve satisfactory outcomes, while multimodal treatment consisted of surgery, chemotherapy and radiotherapy are helpful to improve the prognosis of adult patients with RMS.
