Objective To evaluate the efficacy and safety of aripiprazole treatment for co-morbid attention defi?ciency hyperactivity disorder (ADHD) in children with Tourette syndrome (TS). Methods Forty four TS children with co-morbid ADHD were randomly divided into aripiprazole group and haloperidol group. The aripiprazole group and halo?peridol group received aripiprazole and haloperidol treatment for 12 weeks, respectively. Yale global tic severity scale (YGTSS) and Conners parent symptom questionnaire (PSQ) were used to assess the tic and ADHD symptoms before, 2, 4, 8 and 12 weeks after treatment. Side effects were recorded weekly. Results Repeated measure ANOVA indicated that the main effects of groups was not significant to the YGTSS scores (P>0.05), but significant to the PSQ scores (P<0.05). After 12-week treatment, the YGTSS scores between two groups were not significantly different (P>0.05). The PSQ scores of aripiprazole group were significantly lower than that of haloperidol group. The adverse reactions of aripiprazole group were milder compared with the haloperidol group (P<0.05). Conclusions The present study demonstrates that aripipra?zole has the same efficacy in the treatment of tics as haloperidol, improves co-morbid ADHD symptoms, and its adverse reactions are much less compared with haloperidol.

Objective To explore the effect and mechanism of Kuntai Capsule (KC) on premature ovarian failure in rats.Methods Totally 40 SD female rats were randomly divided into four groups:control group,model group,Kuntai Capsule (KC) group and conjugated estrogens tablets (CET) group.The premature ovarian failure model in rats was made by ig administration of 75 mg/kg tripterygium.After the model was established,rats were continually treated with 0.6 and 0.625 g/kg of KC and CET respectively by ig administration for 36 d.HE staining was used to observe the morphology of ovary and count the number of follicle.The enzyme-linked immunosorbent assay (Elisa) method was used for the detection of follicle stimulating hormone (FSH),luteinizing hormone (LH),serum estradiol (E2),and anti-Mueller tube hormone (AMH) level.The real-time fluorescence quantitative PCR (qRT-PCR) method was used to detect the mRNA expression of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF).Results Compared with control group,the number of primordial follicles,preantral follicles and antral follicles were significantly reduced,the number of atretic follicles was increased (P ＜ 0.05),E2 and AMH significantly decreased (P ＜ 0.05),FSH and LH levels increased significantly (P ＜ 0.05),and the levels of VEGF and bFGF mRNA in model group were significantly decreased (P ＜ 0.05).Compared with model group,the number of primordial follicles,preantral follicles,and antral follicles were significantly increased,the number of atretic follicles was significantly reduced (P ＜ 0.05),E2 and AMH significantly increased (P ＜ 0.05),FSH and LH levels significantly decreased (P ＜ 0.05),and the levels of VEGF and bFGF mRNA in KC group were significantly increased (P ＜ 0.05).Conclusion By regulating the level of hormone and up-regulating the expression of VEGF and bFGF,KC can repair the damaged ovarian tissue and promote the growth and development of the follicle,so as to inhibit the premature exhaustion of mRNA.

Objective To explore the effect of intermittent hypoxia (IH) on RhoA/ROCK pathway in lung and on the muscularization in pulmonary vascular in rat model. Methods Wistar rats (n=40) were randomly divided into two groups:the normal oxygen control group (n=20) and the IH group ( n=20). For 4 weeks, rats in control group and IH group were ex?posed to intermittent normal oxygen (21%O2) or IH (5%-21%O2) respectively. Then, mRNA transcription and protein trans?lation levels of RhoA/ROCK were examined by Real-time PCR and Western blot. Expression of proliferation cell nuclear an?tigen (PCNA) andα-smooth muscle actin (SM-α-actin ) of lung and pulmonary artery were detected by immunohistochemis?try. Results RhoA mRNA transcription level(0.463 ± 0.067 vs 0.182 ± 0.040), ROCK mRNA transcription level(0.384 ± 0.062 vs 0.192 ± 0.052), RhoA protein expression level(0.827 ± 0.065 vs 0.424 ± 0.075)and ROCK protein expression level (0.488±0.088 vs 0.336±0.102)were higher in IH group than those in control group(P<0.05);Levels of PCNA in lung tissue [(54.67±1.80)%vs (9.14±0.91)%], PCNA in pulmonary artery [(49.40±1.21)%vs (8.38±1.13)%], SM-α-actin in lung tis?sue [(42.66±1.63)%vs (35.44±1.41)%] and SM-α-actin in pulmonary artery [(62.62±2.53)%vs (45.54±2.58)%] were also higher in IH group than those in control group(P<0.05). Conclusion Rho/ROCK pathway may play an important role in developing pulmonary hypertension (PH) associated with IH;and IH can promote the muscularization in pulmonary vascular to accelerate PH.

Aim To observate the effect of chemokine receptor(CXCR4) gene transfection on biological behavior of bone marrow mesenchymal stem cells in vitro.Methods Firstly, bone marrow mesenchymal stem cells were divided into three groups:GFP(transfected GFP into MSCs), CXCR4+(transfected CXCR4+ into MSCs) and CXCR4-(transfected CXCR4-into MSCs) group.Then, their capacity of proliferation, differentiation and migration ability (in vitro) was assessed with immunofluorescence cytochemistry method, flow cytometry assay and Transwell cell chemotaxis test.Results The high or low expression of CXCR4 had no effect on their ability of proliferation and differentiation into lung tissue.Compared with GFP group, however, CXCR4+-MSCs group significantly increased the number of migrating cells, while CXCR4——MSCs group showed no change in the number of migrating cells.Conclusions The proliferation and differentiation capacities are not affected by the high or low expression of CXCR4.The high expression of CXCR4 can significantly enhance the migration ability of MSCs to inflammatory lesions, and the low one has no effect on the migration of the cells.After the transplantation of MSCs, CXCR4′s high expression will access to the lesion area to participate in tissue repairing rapidly and largely, significantly enhancing the therapeutic efficacy.

Objective To investigate the abnormal functional connectivity (FC) between the substantia nigra (SN) and the brain motor area in rapid eye movement sleep behavior disorder (RBD) by Unified Parkinson′s Disease Rating Scale (UPDRS), Hoehn-Yahr Scale and resting state functional magnetic resonance imaging (rfMRI).Methods A total of 34 subjects (14 with RBD (RBD group), 12 with Parkinson′s disease (PD group), and 8 age, sex-matched normal controls (control group)) recruited in the Department of Neurology, Henan Provincial People′s Hospital from 2014 to 2015 were enrolled in this study according to international diagnosis criteria.All subjects were examined by UPDRS, Hoehn-Yahr Scale and rfMRI.Results UPDRS scores and Hoehn-Yahr staging were 0.00 (0.00, 3.75) and 0.00 (0.00, 0.50) respectively in the RBD group, which were significantly different from that in the PD group (30.5 (18.75, 33.00) and 1.75 (1.50, 2.50), respectively;Z=-3.782, P<0.05 and Z=-2.963, P<0.05), whereas not significantly different from that in the control group (0.00 (0.00, 0.00),0.00 (0.00, 0.00), respectively;Z=1.16, P>0.05 and Z=1.10, P>0.05).The FC analysis showed alterations from the right SN to bilateral cerebellum respectively among the three groups (Fright cerebellum=12.975, Fleft cerebellum=6.144;P<0.05);furthermore, there were significant increases in the RBD group compared with the PD group (t=-4.602,-5.080, P<0.005).The FC analysis showed reduced correlation from the right SN to the left prefrontal cortex in the RBD and the PD groups compared with the control group (t=-4.899,-3.500, P<0.005), but there was no statistically significant difference between the RBD and the PD groups (t=2.035, P>0.05).Conclusions There was abnormal FC from the SN to motor areas in RBD patients, and partial alterations were similar as PD patients.rfMRI provided an evidence that RBD might be presymptom of PD.

Objective: The cross-sectional study examined associations between gross motor competence and physical fitness in 3-5 years old children. Methods: A convenient sampling method was used to select 201 children aged 3-5 years, to assess gross motor competence, each child accomplished the Test of Gross Motor Development-3(TGMD-3). The level of physical fitness was measured by National Physical Fitness Test, comprising eight different tasks including height, weight, flexibility(sit-and-reach test), balance (walking on a balance beam), explosive force(Standing long jump), strength(Tennis ball throwing), agility(10-shuttle-run test), strength and coordination(Continuous foot jump). Results: With the increase of age, the scores of locomotor skills，object control skills, gross motor competence, height, weight, walking on a balance beam, continuous foot jump, tennis ball throwing and standing long jump were better(P<0.01). Significant differences were not found in the gross motor competence, locomotor skills, 10-shuttle-run test, continuous foot jump, standing long jump and walking on a balance beam(P>0.05). In the object control skills and tennis ball throwing, the boys showed a greater performance(P<0.01). In the sit-and-reach test, girls showed a greater performance(P<0.01). The results revealed a significant relationship between gross motor competence and the following items: 10-shuttle-run test, continuous foot jump, standing long jump, walking on a balance beam, tennis ball throwing(P<0.05). There were no associations among gross motor competence, BMI(r=0.02), sit-and-reach test(r=0.07). There were no associations between gross motor competence and physical fitness in 3-5 years old(r=-0.13-0.21), except for 5 years old children’s object control skills and continuous foot jump(r=0.42). Sex, age, height , BMI (R2=0.05,F=2.62, P>0.05) as well as gross motor competence(△R2=0.04, F=2.00, P>0.05) did not predict physical fitness. Conclusion The results indicated a relationship between motor competence and physical fitness in 3-5 years old. In order to increase the level of physical fitness, the educators should pay attention to the development of children’s gross motor.

Objective:To investigate the mid-term clinical outcomes of arthroscopic vertical mattress suturing for shoulder recurrent anterior dislocation combined with joint laxity.Methods:A retrospective case series study was performed on the clinical data of 11 patients with recurrent anterior shoulder dislocation combined with joint laxity admitted to the First Affiliated Hospital, Army Medical University from January 2018 to September 2021. The patients included 10 males and 1 female, aged 18-38 years [(22.8±5.5)years]. All the patients received treatment with arthroscopic vertical mattress suturing. The Oxford shoulder instability score, Rowe shoulder instability score, and simple shoulder test (SST) score were compared before operation, at 6 months after operation and at the final follow-up. The degree of joint capsule laxity and length of capsular redundancy (evaluated by MRI) were compared before operation and at the final follow-up. The results of the supine apprehension test, re-dislocation and postoperative complications such as iatrogenic vascular and nerve injuries were observed at the final follow-up. Also, the correlation between the radiological changes in the joint capsule and the shoulder function was analyzed by Spearman correlation coefficient.Results:All the patients were followed up for 20-64 months [(40.7±18.6)months]. Before operation, at 6 months after surgery and at the final follow-up, the values of Oxford shoulder instability score were (41.2±4.7)points, (49.5±3.0)points and (57.6±3.0)points; the values of Rowe shoulder instability score were (28.6±9.5)points, (77.7±7.2)points and (94.1±10.9)points; and the values of SST score were (7.6±1.3)points, (9.8±1.0)points and (11.6±0.9)points, respectively. The Oxford shoulder instability score, Rowe shoulder instability score and SST at 6 months after operation and at the final follow-up were significantly better than those before operation, and those at the final follow-up were significantly better than those at 6 months after operation (all P<0.05). The MRI showed that the degree of joint capsular laxity and length of capsular redundancy were 1.5±0.2 and (19.7±2.5)mm before operation and were 1.3±0.2 and (12.9±3.7)mm at the final follow-up, respectively ( P<0.05 or 0.01). The supine apprehension test was negative at the final follow-up, with no re-dislocation or postoperative complications such as iatrogenic vascular or nerve injuries. Correlation analysis showed a negative correlation between the degree of joint capsular laxity and the Oxford shoulder instability score ( r=-0.62, P<0.05) and that of the length of capsular redundancy with the Oxford shoulder instability score ( r=-0.80, P<0.01), the Rowe shoulder stability score ( r=-0.73, P<0.01) and the SST score ( r=-0.75, P<0.01). Conclusions:Arthroscopic vertical mattress suturing has good mid-term clinical outcome for recurrent shoulder anterior dislocation combined with joint laxity, improving the shoulder function and reducing complications, wihch is associated with decreased joint capsule laxity and length of capsular redundancy.
