OBJECTIVEBy using orthogonal design method to optimnize prescription of pulsed electric field at Jiaji (EX- B 2) points for spinal cord injury (SCI).
METHODSFifty six patients of SCI were selected, in which 36 cases were divided into orthogonal design trial and 20 cases were into clinical verification. With 36 patients who received orthogonal design trial, Frankel grading scale was used as observation index to screen optimal prescription of pulsed electric field. Pulse frequency (factor A) included low frequency (factor A(I), 10(2) Hz). moderate frequency (factor A(II), 10(4) Hz) and high frequency (factor A(III), 10(3) Hz); pulse amplitude (factor B) included 0-30 V (factor B ), 0-60 V (factor B(II)) and 0-90 V (factor B(III)); pulse width (factor C) included 0.1 ms (factor C(I)). 0.6 ms (factor C(II)) and 0.9 ms (factor C(III)); acupuncture time (factor D) included one month (DI), three months (D(II)) and five months (D(III)). Twenty patients were used for clinical efficacy observation and the effects of screened optimal pre scription of pulsed electric field at Jiaji (EX-B 2) points combined with regular rehabilitation training on spasm se- verity, score of sensory and motor functions, Barthel index and Frankel score were observed.
RESULTS(1) As results of orthogonal design trial, the optimal prescription was A(III) B(III), C(I), D(III), which were high frequency (10(3) Hz), 0-90 V of pulse amplitude, 0.4 ms of pulse width and 5 months of treatment time. (2) As results of 20 patient clinical verification, Ashworth score, tendon reflex and clonus were all significantly improved (P<0.001, P<0.01), the scores of sensory and motor functions were evidently improvedtl (P<0.001, P<0.05), and Barthel in dex and Frankel score were also enhanced (P<0.001, P<0.05).
CONCLUSIONThe optimal prescription of pulsed electric field at Jiaji (EX-B 2) points for spinal cord injury is high frequency (10& Hz), 0-90 V of pulse amplitude, 0.4 ms of pulse width and 5 months of treatment time. The optimal prescription of pulsed electric field at Jiaji (EX-B 2) points combined with regular rehabilitation could obviously improve spasm severity, enhance senso- ry and motor functions, and ameliorate activity of daily life and Frankel score.

Objective To compare the consistency and correlation of multiple breath-hold (BH) with respiratory-triggered (RT) 1H-MRS for quantification of hepatic lipid content. Methods Sixty subjects were underwent RT 1H-MRS of the liver (Couinaud segment VII) and BH 1H-MRS at 1.5 Tesla Magnetic Resonace Imaging (MRI). The peak areas of water and methylene obtained on RT and BH 1H-MRS were recorded respectively and the liver fat fraction was calculated. Pearson correlation coefficient , Bland-Altman 95% limit of agreement, and concordance correlation coefficient were calculated. Results Mean liver fat fraction measured in RT and BH 1H-MRS were (8.6 ± 8.7)% and (9.4 ± 9.3)% respectively. There was a strong correlation between RT and BH 1H-MRS(r = 0.973, P < 0.000 1, concordance correlation coefficient = 0.95). With the Bland-Altman method, 91.7% data points were within the 95% limits of agreement. Conclusion RT and BH 1H-MRS are alternative tools for intrahepatic lipid quantification. These two methods have a strong correlation and perfect consistency.

Type Ⅰ sialidosis is a neurosomatic disorder related to the storage of lysosomal and induced by shortage of neuraminidase. It is an autosomal recessive disorder, maybe heterogeneous in its onset, clinical manifestations and prognosis. A case of type Ⅰ sialidosis with a missense mutation in the α-N-acetyl-neuraminidase (NEU1) gene is reported. The patient was characterized by reduced visual acuity, ataxia and subcortical myoclonus. Although the macular cherry red spots were not detected in the male patient, his bilateral visual evoked potential showed severely prolonged latencies of P100, which was consistent with continuous decline of his visions. Finally, he was treated with carbamazepine and clonazepam with moderate improvement in the symptom of myoclonus. In order to make the definite diagnosis, the importance of a clinical history integrating all the patient′s clinical manifestations and the mutation in NEU1 gene was highlighted. Regardless of being an uncommon disorder, the burden for those patients with sialidosis was significant. Therefore, this diagnosis in the relevant setting should always be considered.

OBJECTIVETo compare the differences in the clinical efficacy on depression differentiated asdeficiency between the combined therapy of ginger-isolated moxibustion and escitalopram and the simple application escitalopram.
METHODSEighty patients of depression differentiated asdeficiency were randomized into an observation group and a control group, 40 cases in each one. In the control group, escitalopram was prescribed for oral administration, 10 mg a day, after each breakfast. In the observation group, on the basis of the treatment as the control group, the ginger-isolated moxibustion was supplemented at Dazhui (GV 14) and bilateral back-points of fiveorgans[Xinshu (BL 15), Ganshu (BL 18), Pishu (BL 20), Feishu (BL 13) and Shenshu (BL 23)]. Moxibustion was used 5 times a week. Twenty times of moxibustion were taken as one session and totally 3 sessions were required (totally 84 days). After 3 sessions of treatment, the concentration of serum 5-hydroxytryptamine (5-HT) before and after treatment and clinical efficacy were observed in the two groups. After 3 sessions of treatment, escitalopram was taken continuously, 10 mg a day for 9 months in the two groups and the recurrent rate was observed in a half year after discontinuity of medication in the two groups.
RESULTSThe total effective rate was 97.5% (39/40) in the observation group and was 92.5% (37/40) in the control group. The total effective rate was similar between the two groups (both>0.05). The curative and remarkably effective rate was 82.5% (33/40) in the observation group, better than 62.5% (25/40) in the control group (<0.05). The serum 5-HT after treatment was increased as compared with that before treatment in the patients of the two groups (both<0.05), but the diffe-rence was not significant statistically between the two groups (>0.05). The recurrent rate of depression was 7.7% (3/39) in the observation group, lower than 27.0% (10/37) in the control group (<0.05).
CONCLUSIONSThe combined therapy of ginger-isolated moxibustion and escitalopram achieves the better curative and remarkably effective rate as compared with the simple western medicine and it significantly reduces the recurrence of depression.

Gene therapy has been considered as a promising method for treatment of many diseases, such as acquired and genetic diseases. At present, there are two major vehicles for gene delivery including viral vectors and nonviral vectors. Viral vectors appear as high gene transfection efficiency, but some deficiencies such as inflammatory responses, recombination and mutagenesis have limited their use. On account of low pathogenicity, safety and cost-effectiveness, nonviral vectors have been attracted much attention. Cationic polymers are one of the nonviral vectors which have been widely studied. This review focuses on the structure of the cationic polymers and the interaction mechanism between the vector and DNA. We try to provide a framework for the future design and synthesis of nonviral vectors with high transfection efficiency and low toxicity for gene therapy.

Objective:To explore the value of a radiomics nomogram based on T 1WI for prediction of the relapse of osteosarcoma after surgery within 1 year from multicenter data. Methods:The imaging and clinical data of 107 patients with pathologica1ly confirmed osteosarcoma who received neoadjuvant chemotherapy before surgery from 6 hospitals from January 2009 to October 2017 were retrospectively analyzed. A training cohort consisted of 75 patients from firstly enrolled 4 hospitals and an independent validation cohort of 32 patients from other 2 hospitals. Pretreatment T 1WI was used to extract radiomics features. Least absolute shrinkage and selection operator (LASSO) regression was applied to reduce the dimension and then the radiomics signature was constructed to predict the relapse of osteosarcoma after surgery within 1 year in training cohort. Independent clinical risk factors were screened using one-way logistic regression, and then a radiomics nomogram incorporated the radiomics signature and MRI characteristics was developed by multivariate logistic regression. The predictive nomogram was evaluated using receiver operating characteristic (ROC) curve in the training cohort, and validated in the independent validation cohort. The calibration curve was used to evaluate the agreement between prediction and actual observation and the decision curve was used to demonstrate the clinical usefulness. Results:Based on T 1WI from multicenter institutions, the radiomics signature was built using 2 valuable selected features that were significantly associated with relapse within 1 year. Two selected features included 1 gray-level co-occurrence matrices (GLCM) feature (L_G_1.0_GLCM_homogeneity1, LASSO coefficient 3.122) and 1 gray-level run length matrix (GLRLM) feature (GLRLM_RP, LASSO coefficient -2.474). The prediction nomogram including radiomics signature and MRI characteristics (joint invasion and perivascular involvement) showed good discrimination with the area under the ROC curve of 0.884 and 0.821 in the training and validation cohorts, respectively. The calibration curve showed that the nomogram achieved good agreement between prediction and actual observation. Decision curve analysis demonstrated that the radiomics nomogram was clinically useful when the threshold probability was greater than 21%. Conclusion:The radiomics nomogram based on T 1WI can be used as a non-invasive quantitative tool to predict relapse of osteosarcoma within 1 year before treatment, which provides support for clinical decision-making in osteosarcoma.

SAM pointed domain containing E26 transformation-specific transcription factor (SPDEF) plays dual roles in the initiation and development of human malignancies. However, the biological role of SPDEF in head and neck squamous cell carcinoma (HNSCC) remains unclear. In this study, the expression level of SPDEF and its correlation with the clinical parameters of patients with HNSCC were determined using TCGA-HNSC, GSE65858, and our own clinical cohorts. CCK8, colony formation, cell cycle analysis, and a xenograft tumor growth model were used to determine the molecular functions of SPDEF in HNSCC. ChIP-qPCR, dual luciferase reporter assay, and rescue experiments were conducted to explore the potential molecular mechanism of SPDEF in HNSCC. Compared with normal epithelial tissues, SPDEF was significantly downregulated in HNSCC tissues. Patients with HNSCC with low SPDEF mRNA levels exhibited poor clinical outcomes. Restoring SPDEF inhibited HNSCC cell viability and colony formation and induced G0/G1 cell cycle arrest, while silencing SPDEF promoted cell proliferation in vitro. The xenograft tumor growth model showed that tumors with SPDEF overexpression had slower growth rates, smaller volumes, and lower weights. SPDEF could directly bind to the promoter region of NR4A1 and promoted its transcription, inducing the suppression of AKT, MAPK, and NF-κB signaling pathways. Moreover, silencing NR4A1 blocked the suppressive effect of SPDEF in HNSCC cells. Here, we demonstrate that SPDEF acts as a tumor suppressor by transcriptionally activating NR4A1 in HNSCC. Our findings provide novel insights into the molecular mechanism of SPDEF in tumorigenesis and a novel potential therapeutic target for HNSCC.
