Objective To evaluate the role of microRNA130α on rat bone mesenchymal stromal cells(BMSCs)during chondrogenic differentiation.Methods BMSCs were induced to differentiate into chondroeytes by transforming growth factor-β1(TGF-β1)in vitro,immunofluorescence and immunohistochemistry were performed to evaluate MSCs differentiation.RT-PCR was performed to analyze microRNA130α expression at different time points.Results microRNA130α was down-modulated during chondrogenesis after BMSCs been cultured with TGF-β1 for 7 days (P ＜0.05).Conclusion During the early stage of BMSC chondrogenic differentiation,mciroRNA130a expression was specifically repressed,suggesting its role in differentiation of rat bone mesenchymal stromal cells.

Objective To study the clinical, laboratory, radiological and pathological findings of patients with hypertrophic cranial pachymeningitis (HCP) in Wegner's granulomatosis (WG) to improve the recognition of the disease, even when it occurs in limited form. Methods Three patients were described and English literatures of biopsy-proven pachymeningitis in WG were reviewed. Results The features of WG-associated pachymeningitis included: ① Frequently occurred early in the course of active limited WG; ② Commonly presented with sever headache and cranial neuropathies in the absence of other meningeal irritative signs; ③ Variable cerebrospinal fluid findings with mild predominantly lymphocytic pleocytosis and elevated protein concentration were major laboratorg findings; ④Elevated ESR and positive serum anti-neutrophilic cytoplasmic antibody (ANCA) could be found in most patients; ⑤ Gadolinium-enhanced brain MRI is very senitive in the detection of pachymeningitis; ⑥A dural biopsy showed granulomatous necrotizing inflammation, giant cell, and evidence of vasculitis;⑦ A favorable response to standard treatment with corticosteroid, cyclophosphamide or other cytotoxic drugs could be observed. Conclusion HCP may be the initial or cardinal manifestation of the limited form of WG. Early diagnosis by ANCA, MRI and dural biopsy may facilitate diagnosis Corticosteroid and immunosupressant are the choices of treatment.

ACKGROUND:Autism is a kind of neurobiological disease.The increase of plasma concentration of 5 hydroxytryptamine(5 HT) is considered to be one of study results,which is the most definite and has the best repetition,for the biological investigation of autism. Whether the season of birth and maternal mood during pregnancy are correlated with the occurrence of autism? OBJECTIVE:To compare the differences of the plasma concentration of 5 HT,season of birth and the maternal mood during pregnancy between autistic and normal children,and probe into the cause of increased 5 HT in autism. DESIGN:An observational comparative study taking autistic and normal children as the subjects. SETTINGS:A clinical psychological department of a university hospital;Mental Health Institute of the Xiangya Second Hospital;A rehabilitation center for dumb children of city grade. PARTICIPANTS:Children in the autistic group(n=54),who were in accordance with the diagnostic criteria of autism in Diagnostic and Statistical Manual of Mental Disorders Fourth Edition(DSM IV) and had the total score of social adaptive ability scale(SAAS) over 40, were selected from the Outpatient Clinic for Children of the Mental Health Institute,Xiangya Second Hospital of Central South University and the training class of autism of Shenzhen Special Education School;Children in the normal control group,who had no obvious somatic and neurological diseases,and developing delay detected by physical,neurological and mental status examinations, rough detection of developing level,were selected from the primary school and kindergarten in Changsha and Shenzhen cities. INTERVENTIONS:The plasma level of 5 HT was examined, season of birth and maternal mood during pregnancy were investigated in autistic and normal children.The children with autism were accessed with SAAS. MAIN OUTCOME MEASURES:The plasma level of 5 HT,the season of birth and the maternal mood during pregnancy in both groups. RESULTS:The score of SAAS in children with autism was 67.65± 1.67.The plasma level of 5 HT was(0.78± 0.32) μ mol/L in the autistic group,which was significantly higher than that in the normal control group [(0.62± 0.16) μ mol/L](t=3.17,P=0.002). There were 17 children with autism had increased 5 HT.Compare with normal children,most children with autism were born in winter and spring,and their mother had obvious mood problems during pregnancy. CONCLUSION:The 5 HT level is higher in children with autism than in normal children.Most children with autism were born in winter and spring,and their mother had obvious emotional problems during pregnancy.There are phase of high functioning of 5 HT in mother in key period of fetus cerebra development that may be one of the causes of hyperserotonemia in autism,and that is possibly one of the etiologies of autism.

OBJECTIVE: To evaluate the influence of fewer courses and prolonged intervals of chemotherapy on survival rate of advanced non small cell lung cancer (NSCLC) patients treated by sequential chemo-radiation therapy combined with traditional Chinese medicine (TCM). METHODS: From Jan. 2000 to Dec. 2001, 54 untreated advanced NSCLC patients (2 stage IIIa, 18 stage IIIb, 34 stage IV) were treated by sequential chemo-radiation therapy combined with TCM. The courses of chemotherapy were reduced and the intervals of chemotherapy were longer than that of the standard regimen. The efficacy and survival rate were documented and the prognostic factors were analyzed. RESULTS: Complete remission (CR) was observed in 1 case and partial remission (PR) in 20 cases. The overall objective response rate was 40.4%. Median survival was 15.3 months, 1-, 2- and 3-year survival rate were 53.7%, 28.9% and 9.6% respectively. The median survival of stage III and IV were 21.8 months and 12.5 months respectively. The 1-, 2-, and 3-year survival rates of stage III were 65.0%, 49.5%, 24.7% and that of stage IV were 47.0%, 23.3%, 0%, respectively. The quality of life was improved in most of the patients. Cox's proportional hazards regression showed that improved quality of life and treatment of TCM were the significant prognostic factors of overall survival. CONCLUSION: Chemotherapy and radiotherapy combined with TCM is beneficial to extending the interval of chemotherapy, improving the quality of life, and increasing the survival rate of advanced NSCLC patients.

Objective To analyze the clinical characteristics of pneumomediastinum in patients with dermatomyositis and polymyositis for demonstrating its pathogenesis and for predicting its prognosis. Methods The clinical records of 96 patients with PM/DM were reviewed, focusing on for perdicting its pneumomediastinum. Five patients with pneumomediastinum are described in detail. Case reports of pneumomediastinum in PM/DM in English publications are reviewed. Results Five DM cases complicated by pneumomediastinum all had lung infections. Twenty-nine cases (including our five cases) of DM/PM with pneumomediastinum have taken methylprednisolone, four cases alive, and six died. Nine cases have taken CsA,seven cases alive and two died. Conclusion The infections was strongly suspected as being responsible for the pneumomediastinum. Methylprednisolone has poor effect. CsA can be an effective therapeutic agent in PM/DM.

Objective To investigate the changes of major causes of death in patient with dermatomyositis/polymyositis (DM/PM) and the factors affecting the mortality of DM/PM in the past 28 years.Methods Death cases with DM/PM from 1985 to 2013 were retrospectively analyzed.x2 test and Fisher exact test was used for count data analysis;independent samples t-test measurement was used for data analysis;P＜0.05 was consi-dered statistically significant.Results Out of 1 443 patients with DM/PM, 74 died, in whom 48 were female and 26 were male.The mortality rate was 4.7％ among female and 6.3％ among male cases and the total in-hospital mortality of DM/PM was 5.1％.The two most common causes of death in patients with DM/PM were infection and respiratory involvement, accounting for 62.2％ (46/74) and 14.9％ (11/74) respectively.Death occurred most commonly in the first year after disease onset, accounting for 79.7％(59/74).The leading causes of death in the first year were infection and respiratory involvement.The mortality of DM/PM patients was peaked 12.3％(18/146) from 1996 to 2000;infection was the most frequent cause of death.Conclusion Infection and respiratory involvement are the main causes of death in DM/PM.Death occurrs most commonly in the first year after disease onset.

Objective According to international classification criteria (2002) on Sjogren' s syndrome, labial pathology was still considered as a major criterion for diagnosis. Standard labial biopsy was hard to be carried out in China. This study is to evaluate whether the invasive labial biopsy could be replaced by noninvasive detection of serum anti-SSA antibody. Methods 181 Chinese patients with the initial diagnosis of primary Sjogren's syndrome in Peking Union Medical College Hospital (PUMCH) were enrolled in Sjogren's International Collaborative Clinical Alliance (SICCA). All patients received standard labial biopsies (area of salivary gland tissues≥4 mm~2) and focal score (FS) of focal lymphatic sialadenitis were confirmed by pathologists from school of stomatology,University California of San Francisco (UCSF). Anti-SSA antibodies in sera of all patients were detected by double immunodiffusion (DID), Western blot in PUMCH and by enzyme-linked immunosorbent assay (EIJSA) in central laboratory of SICCA. The correlation between labial pathological findings and serum anti-SSA antibody was studied by X~2 test and the concordance was calculated by unweighted Kappa. Results(1)Bivariate analysis revealed strong associations of FS > 1 with the presence of anti-SSA antibody by DID (83.9% vs 42. 0%, P <0. 0001). The accordance between FS and antibody detection by DID was fine with a kappa value of 0. 432. However, there were 16. 1% false-positive antibody reports and 42.0% false-negative antibody reports. (2)FS > 1 was strongly associated with the presence of anti-SSA antibody by Western blot (83.0% vs 51.7%, P < O. 0001). But the accordance between FS and antibody detection by Western blot was only fair with a kappa value of 0. 316. There were 17.0% false-positive antibody reports and 51.7% false-negative antibody reports. (3)FS > 1 was strongly associated with the presence of anti-SSA antibody by ELISA (81.5% vs 38.6%, P <0. 0001). The accordance between FS and antibody detection by EI,ISA was fine with a kappa value of 0.427. There were 18.5% false-positive antibody reports and 38. 6% false-negative antibody reports. Conclusion In Sjogren's syndrome, labial biopsy with FS > 1 finding is strongly associated with anti-SSA antibody. Positive results of anti-SSA antibodies by DID or ELISA may indicate FS > 1, thus labial biopsy could relatively be avoided, negative results may need further standard labial biopsy procedure to confirm the diagnosis of Sjogren's syndrome.

Objective To explore the application of Trinity new model home nursing on continuous control of blood sugar in patients with type 2 diabetes mellitus. Methods Totally 98 patients with type 2 diabetes were selected from January 2016 to December 2017 in our hospital, who were divided into study group and control group by random number table, and there were 49 cases in each group. The control group was given conventional nursing until the hospital was discharged, and the routine follow-up was given after discharge. The study group was given conventional nursing until the hospital was discharged, and the new type of new home nursing mode was given after discharge. The levels of fasting blood glucose (FBG), postprandial 2h blood glucose (2h PBG) and glycated hemoglobin (HbAc1) were compared between the 2 groups at 1d before discharge, 1 months and 3 months after discharge, and the patients compliance were compared, then the quality of life of patients at discharge and 3 months after discharge were assessed by the diabetes specific quality of life scale (DSQL). Results The levels of FBG, 2h PBG and HbAc1respectively were(7.08 ± 0.58) mmol/L, (10.06 ± 0.72) mmol/L, (6.11 ± 0.40)％of the study group at 1d before discharge, of which the control group respectively were(7.07±0.61) mmol/L, (10.07±0.74) mmol/L, (6.10±0.42)％.The levels of FBG, 2h PBG and HbAc1respectively were(6.13±0.44) mmol/L, (9.51 ± 0.55) mmol/L, (5.51 ± 0.30)％of the study group at 1 months after discharge, of which the control group respectively were (6.58 ± 0.56) mmol/L, (9.75 ± 0.53) mmol/L, (5.82 ± 0.34)％ .The levels of FBG, 2h PBG and HbAc1 respectively were(5.69±0.42) mmol/L, (9.03±0.44) mmol/L, (5.22±0.23)％of the study group at 3 months after discharge, of which the control group respectively were (6.17±0.40) mmol/L, (9.46±0.48) mmol/L, (5.51±0.20)％. The levels of FBG, 2h PBG and HbAc1 had significant differences in the interaction between groups and time (F=2.892-5.749, P<0.05). The complete compliance rate of the study group(79.59％, 39/49) was significantly higher than that of the control group (61.22％, 30/49) (χ2=3.967, P=0.046), and then on-compliance rate of the study group (2.04％) was significantly lower than that of the control group (14.29％) (χ2=4.900, P=0.027).The scores of the physiological function, psychology or spirit, social relationship, treatment and DSQL total score of the study group at discharge respectively were (26.62 ± 4.35), (20.21 ± 3.19), (10.36 ± 2.32), (7.42 ± 0.54), (64.61 ± 9.27),of which the control group respectively were(26.49 ± 4.18), (20.17 ± 3.25), (10.45 ± 2.44,(7.35 ± 0.57), (64.46 ± 10.38).The scores of the physiological function, psychology or spirit, social relationship, treatment and DSQL total score of the study group at3 months after discharge respectively were (17.33±3.96), (11.97±2.84), (5.01±1.14), (4.25± 0.49), (38.07±7.12), of which the control group respectively were (21.72±3.51), (15.46±3.08), (7.18±1.85), (5.13 ± 0.48), (49.49 ± 8.74).The scores of the physiological function, psychology or spirit, social relationship, treatment and DSQL total score of the 2 groups at 3 months after discharge were significantly lower than those at discharge (t = 6.117-30.432, all P<0.01), and the scores of each dimension and total score of the study group were significantly lower than those of the control group at 3 months after discharge (t=5.087-8.981, 7.091, all P<0.01). Conclusion The Trinity new model home nursing can obviously improve the blood sugar indexes of patients with type 2 diabetes after discharge, improve the compliance and the quality of life, which has the value of popularization and application.

Objective: To understand the present situation of physical activity and its influencing factors, and to provide a reference for improving the level of physical activity and making the intervention measures. Methods: The method of random stratification was used to select 4 740 pre school children aged 3-6 from 17 kindergartens in 12 counties and districts of Nanchang City, The questionnaire of physical activities of young children and the questionnaire of parents of physical activities of young children were applied to conduct a survey. Results: Compared with weekday PA and MVPA, preschool children’s weekends decreased, SB increased. The differences in PA, MVPA and SB on weekdays and weekends were statistically significant( P <0.01). The proportion of PA and MVPA reaching the recommended amount during the working day of preschool children were 44.9%-59.2%, 45.4%- 61.7%.The proportion reaching the recommended amount of PA and MVPA on weekends were 24.7%-27.8%, 24.5%-29.9%, and the proportion reaching the recommended amount on weekdays was higher than that on weekends. Conclusion There is still gap between actual amount of physical activity and the recommended amount. There are different modes of activity on weekdays and weekends, and weekends are the least active periods. Parents and teachers should pay enough attention to the establishment of "social campus family" model to improve the lack of physical activity of preschool children.

Objective: To investigate the effects of physical activity (PA) intensity and sedentary behavior (SB) on calcanues bone mineral density (BMD) in preschool children, so as to provide a basis for rationalizing the daily physical activity of preschool children to promote bone health. Methods: A total of 673 pre school children aged 3-6 years from nine kindergartens in Pingxiang City, Ganzhou City and Yingtan City of Jiangxi Province, were selected from September to December 2021 by using the whole stratified cluster random sampling method. The PA levels and SB were measured by using a three axis acceleration sensor, and left calcanues BMD was measured by an ultrasound bone densitometer. Multiple linear regression was used to explore the effects of changes in PA on calcanues BMD in pre school children of all ages. Results: Of the 673 preschoolers surveyed, 498 (74.0%) achieved an average of ≥60 min of moderate to vigorous physical activity (MVPA) per day, there were 265 boys (71.2%), and 233 girls ( 77.4 %). The difference between genders was not statistically significant ( χ 2=2.77, P >0.05). There was no statistically significant difference in the BMD test of the calcaneus bones of preschoolers by gender ( Z=0.42, P >0.05). The difference in BMD results of pre school children with 3, 4, 5 to 6 years was statistically significant ( H=2.65, P <0.05). Correlation analysis revealed a negative correlation between SB duration and calcaneus BMD ( r =-0.13), and a positive correlation between low intensity physical activity (LPA) duration, MVPA duration, and calcaneus BMD ( r =0.14, 0.25 ) ( P <0.05). Multivariate linear regression analysis showed that SB duration negatively correlated with calcaneus BMD, whereas LPA and MVPA duration positively correlated with calcaneus BMD ( P <0.05). Conclusions MVPA duration is positively correlated with the growth of BMD in the heel bone and negatively correlated with SB. The kindergartens can adjust their curricula according to the physical and mental developmental characteristics, gender and age differences of pre school children, increase the time of outdoor activities, and reduce the sedentary time to promote the bone health of young children.
