Objective:To determine the clinical application value of transcranial sonography (TCS) in the diagnosis of attention deficit hyperactivity disorder (ADHD) in children.Methods:A total of 50 children aged 6-12 years diagnosed with ADHD (ADHD group) and 45 age-matched healthy children (control group) who presented to Suzhou Municipal Hospital and Children′s Hospital of Soochow University from August 2021 to August 2022 were prospectively enrolled for TCS examination. ADHD was diagnosed in accordance with the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-Ⅴ) criteria established by the American Psychiatric Association.Based on clinical symptom characteristics, ADHD was further classified into 3 subtypes, including 14 cases of predominantly inattentive, 3 cases of predominantly hyperactive/impulsive, and 33 cases of combined presentation. The substantia nigra(SN) hyperechoic area and the ratio of SN hyperechoic area to midbrain area (S/M) were measured and compared between the two groups. The examination of the correlation was performed between SN hyperechoic area, S/M ratio, and DSM-Ⅴ scores within the ADHD group.Results:Semi-quantitative analysis: the proportion of the SN grade Ⅲ or more in ADHD group was significantly higher than that in control group [96.00%(48/50) vs 13.3%(6/45), P<0.05]. Quantitative analysis: the area of SN hyperechogenicity and the ratio of S/M were significantly larger in ADHD group than in control group [0.32(0.22, 0.38)cm 2 vs 0.00(0.00, 0.00)cm 2, 7.08(5.11, 8.75)% vs 0.00(0.00, 0.00)%, all P<0.05]. Correlation analysis: The SN hyperechoic area and S/M ratio showed no significant correlations with DSM-Ⅴ scores in the ADHD group ( r=0.144, 0.142, all P>0.05). Conclusions:TCS can detect the SN echo enhancement of ADHD children, and the proportion of SN echo enhancement, SN hyperechoic area and S/M ratio are significantly higher than those of normal children, but the SN hyperecho area and S/M ratio are not significantly correlated with DSM-Ⅴ scores.

As an important complementary form of decoction pieces of traditional Chinese medicine（TCM）， TCM dispensing granules has the advantages of being free of decoction， easy to take， easy to carry and easy to be dispensed， which greatly improves the capacity of emergency services of TCM and is more in line with the needs of modern society. With the end of the pilot project of TCM dispensing granules， the market has been fully liberalized， the competition has been intensified， and it is in the transition period of switching between the new standard and the old one， and there are some problems such as the shortage of varieties， the change of specifications and the difference of quality， and the production enterprises are facing new opportunities and challenges. Based on this， the authors intend to systematically sort out the policies and regulations， enterprise layout and standard formulation since the pilot of TCM dispensing granules. In view of the problems in the post-pilot stage and from the perspective of survival and development of enterprises， it is suggested that enterprises should establish a quality control system for the whole industry chain of TCM dispensing granules to reduce process costs and increase enterprise competitiveness， further increase the investment in scientific research， overcome the key technical problems of difficult varieties， actively and orderly promote the research of national standards， in order to ensure the integrity of clinical formula varieties， and establish and improve the efficacy evaluation mechanism of TCM dispensing granules， build a consistency evaluation system between TCM dispensing granules and decoction pieces. Government departments should strengthen the guidance， fully mobilize the enthusiasm of scientific research institutions， enterprises and hospitals， and explore the establishment of "government-industry-study-research-application" mode to promote the development of TCM dispensing granule industry.

OBJECTIVE: We propose a sparse-view helical CT iterative reconstruction algorithm based on projection of convex set tensor total generalized variation minimization (TTGV-POCS) to reduce the X-ray dose of helical CT scanning. METHODS: The three-dimensional volume data of helical CT reconstruction was viewed as the third-order tensor. The tensor generalized total variation (TTGV) was used to describe the structural sparsity of the three-dimensional image. The POCS iterative reconstruction framework was adopted to achieve a robust result of sparse-view helical CT reconstruction. The TTGV-POCS algorithm fully used the structural sparsity of first-order and second-order derivation and the correlation between the slices of helical CT image data to effectively suppress artifacts and noise in the image of sparse-view reconstruction and better preserve image edge information. RESULTS: The experimental results of XCAT phantom and patient scan data showed that the TTGVPOCS algorithm had better performance in reducing noise, removing artifacts and maintaining edges than the existing reconstruction algorithms. Comparison of the sparse-view reconstruction results of XCAT phantom data with 144 exposure views showed that the TTGV-POCS algorithm proposed herein increased the PSNR quantitative index by 9.17%-15.24% compared with the experimental comparison algorithm; the FSIM quantitative index was increased by 1.27%-9.30%. CONCLUSIONS The TTGV-POCS algorithm can effectively improve the image quality of helical CT sparse-view reconstruction and reduce the radiation dose of helical CT examination to improve the clinical imaging diagnosis.

Objective To follow up the rehabilitation, education, and assistive devices utilization of school age children with cerebral palsy. Methods From 2012 to 2015, 80 children with cerebral palsy were called their parents with telephone and filled in the questionnaires. Results 69 children (85.25%) continued to receive rehabilitation, 11 children (13.75%) stopped rehabilitation. 42 children (56.25%) received education in ordinary schools, 15 children (18.75%) received education in special schools, 4 children (5.00%) were nursed in nursing institu-tion, 16 children (20.00%) stayed at home and did not receive any education. The main problem and needing at present were receiving reha-bilitation, receiving school education, relief the rehabilitation cost of more than one institution, etc. 61 children (76.25%) ever applied for as-sistive devices, 19 children (23.75%) did not. The feedback of application process in order were smoothly;applied, but didn't get;the assis-tive devices that received was inappropriate. 29 children (73.75%) needed assistive devices currently, 21 children (26.25%) did not. When asked the category of needed assistive devices at present, 19 parents (20%) answered that they did not know the category of assistive devices well or they did not know which kind of assistive devices they needed. Conclusion It is important to provide quality and quantity rehabilita-tion and education service, popularize the knowledge of assistive devices and their clinical application for cerebral palsy children. Assistive devices providing departments should do more communication with cerebral palsy children and their parents, in order to reduce the waste of resources, and increase the rational use of resources, and provide more benefits for children with disabilities.

Objective To evaluate the efficacy and safety of domestic human recombinant FSH (rhFSH) in women with anovulation of WHO groupⅡ. Methods A randomized, blind, parallel-controlled, non-inferiority and multicenter study was performed. A total of 534 admitted to 13 hospitals from May 2008 to August 2009. There were 531 women with ovulatory disorder was included in the statistical analysis, were randomly divided into test group (domestic rhFSH, n=352) and control group (imported rhFSH, n=179). Percentage of cycle with mature follicle, ovulation rate, clinical pregnancy rate, multiple pregnancy rate, ovarian hyperstimulation syndrome (OHSS) and adverse events were observed. Results No statistical significant differences (P>0.05) were observed between the two groups in terms of the efficiency on mature follicle [91.8%(323/352) versus 88.8%(159/179)], ovulation rate [91.3%(295/323) verus 90.6%(144/159)], clinical pregnancy rate [19.2%(62/323) verus 18.2%(29/159)], the number of the follicles<14 mm, the level of serum LH and progesterone, the thickness of endometrium on the day of hCG administration. The number of follicle≥18 mm and 14 mm≤follicle<18 mm and the level of serum estradiol on the day of hCG in the test group were significantly higher than those in the control group (P<0.05). The number of days of rhFSH administration in the test group was significantly less than that in the control group [(9.8±2.2) versus (11.4± 0.6) days, P<0.05], the dosage of rhFSH was significantly lower than that in the control group [(879 ± 419) versus (1 043 ± 663) U, P<0.05]. The multiple pregnancy rate in the test group was significantly higher than that in the control group [21% (13/62) versu 10% (3/29), P<0.05]. The incidence of OHSS and adverse events were similar between the two groups (P>0.05), and no other adverse events were observed in test group during treatment. Conclusion Ovarian stimulation with domestic rhFSH is effective, safe and economical in women with anovulation of WHO groupⅡ.

BACKGROUNDBone damage around the joints is one of the major pathophysiological mechanisms that leads to rheumatoid arthritis (RA) chronic disability. Serum tartrate-resistant acid phosphatase 5b (TRACP-5b) is secreted by osteoclasts, its activity can be used as a clinically relevant bone resorption marker. The aim of this study was to test whether the measurement of serum levels of TRACP-5b in patients with RA would correlate with measures of disease activity and with responses to therapy.

METHODSFifty-six patients were randomly assigned to receive recombinant human cytotoxic tlymphocyte-associated antigen-4 immunoglobulin (RhCTLA4-Ig), infliximab or methotrexate (MTX). The clinical and serologic indicators of RA activity were evaluated at baseline and at 24 weeks. Serum TRACP-5b was measured by Enzyme-linked Immunosorbent Assay (ELISA) at 0, 12 and 24 weeks. Hand X-rays were obtained at baseline.

RESULTSAt baseline, the levels of TRACP-5b correlated with the severity of X-ray damage, disease duration (r = 0.332, P = 0.012), and tender joint count (r = 0.408, P = 0.002). The 24 weeks values of TRACP-5b for RhCTLA4-Ig group and infliximab group differed significantly from the baseline values in each group (P < 0.05; P < 0.05), whereas only the value for RhCTLA4-Ig group differed significantly from the 24 weeks value for the MTX group (P < 0.01). Considering the two biologics-treated groups together, the TRACP-5b levels at 24 weeks differed significantly from the baseline values only in those patients who reached an ACR70 level (P < 0.05).

CONCLUSIONSMeasurement of serum TRACP-5b in RA patients reflects clinical and radiological measures of disease activity, treatment with certain biologics, and degree of response to therapy. TRACP-5b should be investigated further as a potential biomarker to predict response to therapy, including slowing of radiographic progression.

[Objective]To study the effect of curcumin on the cholesterol metabolism of nonalcoholic fatty liver disease(NAFLD) cells model induced in vitro and its potential mechanism. [ Methods]The cellmodel of nonalcoholic fatty liver disease(NAFLD) was established by oleic acid and treated with curcumin. The method of oil red O staining was used to observe accumulation of intracellular lipid while the intracellular content of TG, FC and TC was detected by enzymatic method. Meanwhile, the mRNA levels of SR-BΙand HMGCR were detected with qPCR.[ Results] The NAFLD cellmodel was successful y established by culturing with 30 μg·mL-1 oleic acid. After curcumin intervention, TG, FC and intracellular lipid accumulation levels were significantly reduced in NAFLD cellmodel. Meanwhile, curcumin can reduce HMGCR mRNA expression and raise SR-BΙ mRNA expression. [Conclusion] Curcumin can decrease FC level in NAFLD cellmodel and the mechanism might be related with its capacity of restraining endogenous cholesterol biosynthesis and promoting foreign cholesterol transfer into the liver cells for metabolism.
