Objective: This prospective study evaluated the feasibility of chemical exchange saturation transfer (CEST) MRI for assessing disease activity in thyroid-associated ophthalmopathy (TAO). Materials and Methods: A total of 88 patients with active TAO, 76 with inactive TAO, and 30 healthy controls were enrolled. CEST MRI-derived magnetization transfer ratio (MTR) and MTR asymmetry (MTRasym) at 1 ppm, 2 ppm, and 3.5 ppm were calculated. Clinical data, MTR, and MTRasym values for the extraocular muscles (one representative muscle per eye, yielding two measurements per participant) were compared among the groups. Spearman’s correlation was used to examine associations between imaging parameters and the clinical activity score (CAS) in patients with TAO. Logistic regression analysis was used to identify independent associations between imaging parameters and disease activity in patients with TAO (active vs. inactive). Receiver operating characteristic (ROC) analysis was conducted to evaluate the diagnostic performance for discriminating active from inactive TAO. Results: Patients with active TAO showed lower MTR values (P < 0.001) and higher MTRasym (1 ppm), MTRasym (2 ppm), and MTRasym (3.5 ppm) (all P < 0.001) compared with those with inactive TAO. MTR was negatively correlated with CAS (r = -0.402; P < 0.001), while MTRasym (1 ppm), MTRasym (2 ppm), and MTRasym (3.5 ppm) were positively correlated with CAS (r = 0.369, 0.350, and 0.349, respectively;all P < 0.001). MTR and MTRasym (1 ppm) were independently associated with TAO activity. The areas under the ROC curve (AUCs) for MTR and MTRasym (1 ppm) in discriminating active from inactive TAO were 0.772 and 0.730, respectively. Combining MTR with MTRasym (1 ppm) significantly improved diagnostic performance compared with either parameter alone, achieving an AUC of 0.805 (P = 0.029 and 0.001). Conclusion MTR and MTRasym (1 ppm) were independently associated with TAO activity. Their combination further enhanced diagnostic performance in distinguishing active from inactive TAO, suggesting their potential as quantitative imaging biomarkers to guide treatment in patients with TAO.

A 57-year-old male patient with epilepsy was additionally given topiramate 25 mg orally once at night because of poor curative effect of sodium valproate. Seven days later, the patient developed vision loss with eye pain and swelling. Ocular ultrasonography showed bilateral choroidal detachment, which was considered to be related to topiramate. Topiramate was discontinued and prednisone acetate 60 mg once daily was given, and 8 days later, the patient′s eye pain and swelling were improved. Ocular ultrasonography showed that choroidal detachment disappeared. Fifteen days after drug withdrawal, his ocular symptoms disappeared.

The current outpatient payment method based on fee-for-service induced serious demand, which increased the waste of medical insurance fund. The authors briefly introduced ambulatory patient groups(APG)with the same concept of diagnosis-related groups. According to the current situation of outpatient medical insurance payment and the degree of informatization in China, suggestions are put forward: launch a pilot project first and starting with chronic disease to promote reform; improve the quality of outpatient electronic medical records, and develop APG suitable for China; under the background of aging, cooperate with the total budget to ensure the security of medical insurance.

When facing a sudden danger or aversive condition while engaged in on-going forward motion, animals transiently slow down and make a turn to escape. The neural mechanisms underlying stimulation-induced deceleration in avoidance behavior are largely unknown. Here, we report that in Drosophila larvae, light-induced deceleration was commanded by a continuous neural pathway that included prothoracicotropic hormone neurons, eclosion hormone neurons, and tyrosine decarboxylase 2 motor neurons (the PET pathway). Inhibiting neurons in the PET pathway led to defects in light-avoidance due to insufficient deceleration and head casting. On the other hand, activation of PET pathway neurons specifically caused immediate deceleration in larval locomotion. Our findings reveal a neural substrate for the emergent deceleration response and provide a new understanding of the relationship between behavioral modules in animal avoidance responses.

OBJECTIVETo explore the repair effects of acupuncture for promoting the governor vessel and tranquilizing the mind (acupuncture technique) on cerebral white matter injury of premature infants.

METHODSA total of 56 cases of cerebral whiter matter injury of premature infants, the fetal age less than 35 weeks were selected and randomized into an observation group (27 cases) and a control group (29 cases). The routine basic rehabilitation therapy was used in the two groups. Additionally, in the observation group, the acupuncture technique was added, once a day and the treatment for 15 days was as 1 course. Totally, 3 courses of treatment were required. Before and after treatment, the cranial magnetic resonance imaging (MRI) and the diffusion tensor imaging (DTI) were adopted to observe the location and severity of cerebral white matter injury. The Gesell developmental scale was used to assess the nerve motor development.

RESULTSAfter treatment, the difference was not significant statistically in the severity of cerebral white matter injury in the infants between the two groups (>0.05). The FA value of cerebral white matter in the interesting zone was increased as compared with that before treatment in the infants of the two groups (both<0.05). The result in the observation group was higher than that in the control groups (<0.05). After treatment, DQ value of each function zone in Gesell scale was all increased as compared with that before treatment in the two groups (all<0.05). After treatment, the DQ values of gross motor, fine motor and social adaptability in the observation group were higher than those in the control group (all<0.05). After treatment, the difference was not significant in DQ value of individual-social and speech behaviors between the two groups (both>0.05).

CONCLUSIONAcupuncture technique for promoting the governor vessel and tranquilizing the mind promotes the repair of the function in the premature infants with cerebral white matter injury and further benefits the promotion of the intelligence.

Objective To investigate the effect of complement C3a on mouse podocytes phenotype transformation.Methods Purified C3a recombinant protein was used to stimulate mature mouse podocytes.The expression of the mature podocyte markers synaptopodin,podocin,nephrin,CD2-associated protein (CD2AP) and the mesenchymal cell markers fibroblast specific protein 1 (FSP-1),α-smooth muscle actin (α-SMA) were detected by RT-PCR,Western blotting,immunochemistry and immunofluorescence,respectively.Some podocytes were transfected with integrin-linked kinase (ILK) siRNA before the administration of C3a,the expression of nephrin and α-SMA were accessed by Western blotting,and the expression of Snail and α-actinin 4 were accessed by Western blotting and immunochemical method.The migration ability of podocytes was observed by scratch test.Results Immunocytochemistry and immunofluorescence analysis showed that synaptopodin,podocin,nephrin,CD2AP were highly expressed by mature mouse podocytes.The expression of these podocyte markers could be markedly inhibited after 24 h of C3a (0.1 μmol/L) treatment,and accompanied by the induction of mesenchymal markers FSP-1 and α-SMA.Compared with control group,the mRNA levels of synaptopodin,podocin,CD2AP and nephrin were significantly repressed by the administration of C3a in a dose-dependent manner,whereas the transcription of FSP-1 and α-SMA were remarkably up-regulated by C3a treatment (P ＜ 0.05,respectively).Western blotting analysis also confirmed the decrease of synaptopodin,podocin,nephrin and CD2AP protein and the increase of FSP-1 and α-SMA protein were closely depend on the C3a concentration (P ＜ 0.05,respectively).To further assess the downstream of C3a,some podocytes were transfected with ILK siRNA before the administration of C3a.Compared with C3a group,the protein levels of nephrin and α-SMA were significantly changed by the administration of ILK siRNA (P ＜ 0.05,respectively).The expression of α-actinin 4 and Snail induced by C3a were inhibited by ILK knockdown (P ＜ 0.05,respectively),accompanied by a decline of cell migration potency.Conclusion Complement fragment C3a can induce transformation of mouse podocytes to mesenehymal cells,and ILK signaling pathway is involved in this cell type transformation.

OBJECTIVETo explore the effect of scalp acupuncture for children with cerebral palsy whose video-electroencephalogram(VEEG) showed epileptiform discharges.

METHODSA total of 184 children with cerebral palsy whose VEEG showed epileptiform discharges or those combined with epilepsy were randomly assigned into a combination group (99 cases) and a rehabilitation group (85 cases). All the cases were treated with the original antiepileptic drugs. The conventional physical training and massage were applied in the rehabilitation group for 3 courses with 20 d at the interval, once a day, 5 times a week and 15 times as one course. Based on the treatment as the rehabilitation group, scalp acupuncture was used in the combination group for 3 courses with 15 d at the interval, once the other day and 10 times as one course. Shenting (GV 24), Benshen (GB 13), Sishencong (EX-HN 1) were selected as the main acupoints, combined with motor zone, foot motor-sensory area, balance zone,and temple-three-needle etc. Clinical onset and VEEG results were observed before and after treatment.

RESULTSAfter treatment in the combination group, 27 cases improved; 47 cases had no effect; 25 cases aggravated. While in the rehabilitation group, 11 cases improved; 46 cases had no effect; 28 cases aggravated. There was no statistically significance between the two groups (>0.05). As for the cases with epilepsy onset in the combination group, 8 cases improved; 4 cases had no effect; 4 cases aggravated. In the rehabilitation group, 4 cases had no effect; 7 cases aggravated. The result in the combination group was better than that in the rehabilitation group (<0.05). As for the cases with epileptiform discharges in the combination group, 19 cases improved; 43 cases had no effect; 21 cases aggravated. In the rehabilitation group, 11 cases improved; 42 cases had no effect; 21 cases aggravated. There was no significance between the two groups (>0.05).

CONCLUSIONSScalp acupuncture therapy does not increase the risk of onset or epileptiform discharges in the children with cerebral palsy combined with epilepsy or epileptiform discharges. Scalp acupuncture combined with rehabilitation is better than simple rehabilitation for thosewith cerebral palsy and epilepsy onset.

Objective:To observe the effect of Governor Vessel-unblocking and mind-refreshing needling technique on diffusion tensor imaging (DTI) in cerebral palsy (CP) children with periventricular leukomalacia (PVL) and investigate the underlying mechanism.
Methods:A total of 18 CP children with PVL received modern rehabilitation training and scalp acupuncture. The before-after study was conducted to compare the fractional anisotropy (FA) of the white matter fiber tracts, gross motor function measure (GMFM) score, Gesell developmental scale and changes in muscle tone.
Results:For the comparison before and after the first course of treatment, there were no statistical differences in DTI findings and FA values (both P>0.05); there were statistical differences in GMFM dimensions A and B (bothP<0.05) and no statistical differences in dimensions C, D and E (allP>0.05); and there were statistical differences in six items of Gesell development test (P<0.01 orP<0.05). For the comparison before and after two courses of treatment, there were statistical differences in DTI findings and FA values in 8 cases between before and after 30 and 60 treatments (bothP<0.05); there were statistical differences in GMFM dimensions A, B and C between before and after 30 and 60 treatments and between 30 and 60 treatments (allP<0.05); there were no statistical differences in GMFM dimensions D and E (allP>0.05); and there were statistical differences in six items of Gesell developmental test between before, after 30 and 60 treatments and between 30 and 60 treatments (P<0.05 or P<0.01).
Conclusion:The Governor Vessel-unblocking and mind-refreshing scalp acupuncture has no significant efficacy on the repair and regeneration of white matter fibers in children with PVL and CP in a short period of time; however, it gradually works along with the prolonged treatment time. In addition, it can improve the motor function and mental development and the efficacy is closely associated with the time of treatment.

Objective:To observe the clinical efficacy of Governor Vessel-unblocking and brain-refreshing scalp acupuncture for cerebral palsy (CP) complicated with intellectual disabilities. Methods:A total of 300 CP cases aged between 1 and 5 years were randomly allocated into a treatment group (n=150) and a control group (n=150). Patients in the treatment group were treated with Governor Vessel-unblocking and brain- refreshing scalp acupuncture combined with rehabilitation training, whereas patients in the control group received rehabilitation training alone. The Beijing Gesell developmental (Gesell) scale and gross motor function measure (GMFM) scale were used to assess the motor and intellectual development before and 3 months after the treatment. In addition, the head CT/MRI examination was applied to assess the brain nerve repair before and after the treatment. Results:After the treatment, the total effective rate in the treatment group was 78.0%, versus 42.7% in the control group, showing a statistical significance (P<0.05). As for scores of five subscales in the Gesell scale, there were significant intra-group differences in the treatment group (allP<0.05); and the scores in the treatment group were significantly better than those in the control group (allP<0.05). As for scores of five dimensions in GMFM scale, there were significant intra-group differences in the treatment group (allP<0.05); and the scores in the treatment group were significantly better than those in the control group (allP<0.05). According to the head CT/MRI findings, the total effective rate was 73.3% in the treatment group, versus 62.0% in the control group, showing a statistical significance (P<0.05). Conclusion:When used in combination with rehabilitative training, Governor Vessel-unblocking and brain-refreshing scalp acupuncture can significantly improve the clinical efficacy for cerebral palsy complicated with intellectual disabilities. It can also improve the patients' motor function, intelligence and language ability.
