ABSTRACT

The mammalian target of rapamycin (mTOR)-sterol regulatory element-binding proteins (SREBPs) signaling promotes lipogenesis. However, mTOR inhibitors also displayed a significant side effect of hyperlipidemia. Thus, it is essential to develop mTOR-specific inhibitors to inhibit lipogenesis. Here, we screened the endogenous inhibitors of mTOR, and identified that FKBP38 as a vital regulator of lipid metabolism. FKBP38 decreased the lipid content

ABSTRACT

@#To improve the standard of quality control of tazobactam and its preparations in China, national reference standard of tazobactam impurity A was developed. After tazobactam impurity A was synthesized, its structure was validated by infrared (IR), mass spectrometry (MS) and nuclear magnetic resonance (NMR), and its content uniformity and short-term stability were measured and investigated. Then, water content and residue on ignition of impurity A were determined, and its purity was determined using high performance liquid chromatography (HPLC) with 10 mmol/L ammonium acetate solution-acetonitrile (98∶2) as the mobile phase. Mass balance method was used to determine the content of the first batch of tazobactam impurity A national standard substance. Meanwhile, nuclear magnetic quantitative method was used to calculate the content, which was mutually verified with the mass balance method. The developed reference material of tazobactam impurity A is consistent with the maximum degradation impurity in tazobactam system applicability solution and the reference material of tazobactam related substance A contained in USP41. Within the 95% confidence range, the ratio of inter- and intra-bottle variance of impurity A after separation was 0.61 (< F0.05(11,12)), proving that the uniformity was satisfying. The contents of organic impurity, water content and inorganic impurity in impurity A were 0.90%, 1.24% and 0.25%, respectively. The content of impurity A was determined to be 97.6% by mass balance method, which was basically consistent with the result of nuclear magnetic quantitative method (97.1%). Under the condition of 25 °C, the area normalized purity of impurity A was 99.1% at 0, 3, 5 and 10 days, proving that the sample was stable at room temperature for 10 days. Finally the first batch of national standard substance of tazobactam impurity A was established successfully.

ABSTRACT

BACKGROUND@#The pathogenesis of osteosarcoma (OS) is still unclear, and it is still necessary to find new targets and drugs for anti-OS. This study aimed to investigate the role and mechanism of the anti-OS effects of miR-296-5p.@*METHODS@#We measured the expression of miR-296-5p in human OS cell lines and tissues. The effect of miR-296-5p and its target gene staphylococcal nuclease and tudor domain containing 1 on proliferation, migration, and invasion of human OS lines was examined. The Student's t test was used for statistical analysis.@*RESULTS@#We found that microRNA (miR)-296-5p was significantly downregulated in OS cell lines and tissues (control vs. OS, 1.802 ± 0.313 vs. 0.618 ± 0.235, t = 6.402, P < 0.01). Overexpression of miR-296-5p suppressed proliferation, migration, and invasion of OA cells. SND1 was identified as a target of miR-296-5p by bioinformatic analysis and dual-luciferase reporter assay. Overexpression of SND1 abrogated the effects induced by miR-296-5p upregulation (miRNA-296-5p vs. miRNA-296-5p + SND1, 0.294 ± 0.159 vs. 2.300 ± 0.277, t = 12.68, P = 0.003).@*CONCLUSION@#Our study indicates that miR-296-5p may function as a tumor suppressor by targeting SND1 in OS.

ABSTRACT

Objective:To investigate the protective effect of glycyrrhizic acid (GA) from tumor necrosis factor-α+actinomycetes ketone (TNF-α+CHX) induced apoptosis in rat small intestine crypt epithelial cell line (IEC-6) via AU rich element mRNA binding protein HuR mediated posttranscription of p21 and the potential mechanism. Method:The cultured IEC-6 cells were observed. The experiment was divided into blank group, GA (60 μmol·L-1) group, TNF-α+CHX group and GA+TNF-α+CHX group. Cytoplasmic and nuclear HuR were measured by Western blot. The interaction of HuR and p21 mRNA was detected by biotin pull down and RNA IP. Luciferase activity was measured after transfection with construct with p21 3'-UTR cloned into downstream of luciferase reporter. Cell apoptosis was detected by real-time dynamic cell analyzer, p21 and cysteine proteinas-3 precursor protein(proCaspase-3) association was analysised by CO-IP. Result:After GA treatment for 48 h, cytoplasmic HuR protein expression increased(P<0.05),the binding between HuR and p21 mRNA expression up regulated(P<0.05), luciferase activity increased(P<0.01), and p21 mRNA and protein expression also increased(P<0.05), while these results were abolished by HuR silencing with siRNA. GA enhanced p21 and procaspase3 interaction(P<0.05), and attenuated TNF-α+CHX induced apoptosis in IEC-6 cells. Conclusion:GA protected IEC-6 cells from TNF-α/CHX induced apoptosis via HuR mediated p21 posttranscription, which due to GA enhanced HuR binding to endogenous and recombinant p21 mRNA and increased p21 interaction with proCaspase3.

ABSTRACT

Objective:To explore the significance of empathy and executive function indexes in the diagnosis and classification of autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD).Methods:According to DSM-Ⅴ diagnostic criteria, 33 children with ASD, 30 children with ADHD and 39 typical development (TD) children and adolescents were enrolled as the research subjects.The empathy and executive function characteristics were compared and analyzed in the subjects.Based on empathy and executive function indicators, the three groups of subjects were diagnosed and classified by machine learning method.Results:The total score of Griffith empathy measure parent ratings(GEM-PR)(ASD: (0.67±0.64), ADHD: (1.00±0.79), TD: (0.98±0.73)) and each factor score ( F=3.595-10.363, all P<0.05) and the total score of behavior rating inventory of executive function(BRIEF)(ASD: (62.79±7.45), ADHD: (59.47±8.77), TD: (49.08±7.91)) and each factor score of the three groups were different ( F=6.557-33.205, all P<0.01). Among them, the scores of empathy and executive function in ASD and ADHD groups were generally higher than those in TD children (all P<0.05). When combined with BRIEF scale and GEM scale, the classification accuracy of the three groups reached 62.75%. Conclusion:Both ASD and ADHD children have damages in empathy and executive function.Combining empathy and executive function indexes are more helpful for diagnosis and classification than single index.

ABSTRACT

Congenital myasthenic syndrome (CMS) is a group of clinical and genetic heterogeneous diseases caused by impaired neuromuscular transmission due to genetic defects. At present, it has been reported that more than 30 genes can cause CMS. All CMS subtypes have the clinical features of fatigue and muscle weakness, but age of onset, symptoms, and treatment response vary with the molecular mechanisms underlying genetic defects. Pharmacotherapy and symptomatic/supportive treatment are the main methods for the treatment of CMS, and antisense oligonucleotide technology has been proven to be beneficial for CHRNA 1-related CMS in animals. Since CMS is a group of increasingly recognized clinical and genetic heterogeneous diseases, an understanding of the latest knowledge and research advances in its clinical features, genetic research, and treatment helps to give early diagnosis and treatment as well as gain a deeper understanding of the pathogenesis of CMS, so as to make new breakthroughs in the treatment of CMS.

ABSTRACT

OBJECTIVE@#To conclude of the technical notes of percutaneous transforaminal endoscope-assisted lumbar interbody fusion (PT-Endo-LIF), and to investigate its safety and efficacy for treatment of degenerative lumbar disease.@*METHODS@#Twenty-four patients were treated by PT-Endo-LIF combined with posterior percutaneous pedicle screws fixation from October 2017 to April 2018. There were 16 males and 8 females, ranging in age from 39 to 72 years old, with a mean of (59.6±9.5) years old. There were 15 cases diagnosed with lumbar intervertebral disc herniation combined with degenerative disc, the other 9 cases were diagnosed as low level lumbar spondylolistheses w/o segmental instability. Single segmental fusion was performed for 22 cases(one for L₂,₃, 3 for L₃,₄ and 18 for L₄,₅) and 2 segmental fusion was performed for the other 2 cases (both for L₃,₄ and L₄,₅). PT-Endo-LIF was performed under local anesthesia with conscious sedation, followed by decompression through endoscopic technics. After that, end-plate preparation and autogenous bone and expandable cage implantation were performed. Finally, percutaneous screws and rod instrumentation were used. The visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to evaluate the clinical efficacy. The operation time, intraoperative bleeding volume, intraoperative and postoperative complications were recorded. All patients underwent X-ray, CT plain scan, three-dimensional reconstruction and MRI examination to evaluate the stability of the implants and fusion rate before 3 days and 1, 3, 6, 12 and 18 months after operation.@*RESULTS@#All patients were followed up, and the duration ranged from 12 to 18 months. The operation time of single-segment fusion was (192.3±22.7) min, and that of double-segment fusion was (272.5±24.7) min. The estimated intraoperative bleeding volume was less than 50 ml per segment, and no blood transfusion was performed in all patients. The VAS improved from preoperative 7.4±1.1 to postoperative 2.3±0.8 (=-19.65, <0.000 5). The ODI improved from preoperative (41.2±3.3)% to the final follow-up (12.3±2.5)%(=-35.76, <0.000 5). Postoperative complications occurred in 4 cases, and contralateral radicular symptoms occurred in 2 cases. After contralateral foraminoscopic decompression, the symptoms were completely alleviated. One case had neurological symptoms related to percutaneous screw placement, and the symptoms were alleviated after removal of the lateral screw rod internal fixation. The other cases had surgical incision infection and improved after debridement and suture. At the latest follow-up, no displacement or loosening of the fusion cage and screw rod system occurred in all patients, and 14 cases showed signs of fusion.@*CONCLUSIONS@#PT-Endo-LIF is a minimal invasive, safe and efficient surgical procedure for treatment of degenerative lumbar disease. Nevertheless, the long-term results still need to be confirmed by a multi-center and lagre sample follow-up study.

ABSTRACT

Objective@#To evaluate the utility of the BRAFV600E mutation detection in different cytoloy categories and to determine if the VE1 antibody can serve as a screening tool for the detection of BRAFV600E mutation in thyroid fine needle aspiration (FNA) specimens.@*Methods@#A total of 273 FNA residual specimens were collected. BRAFV600E testing was performed on these liquid-based specimens. And also 78 specimens with enough residual cells were stained with VE1 antibody. Comparisons of molecular and immunocytochemistry results with clinicopathological outcomes were performed. SPSS 17.0 software was used to analyze the data.@*Results@#There were 70 indeterminated diagnoses in 273 cases with FNAs. Fifty-eight cases were proven to be papillary thyroid carcinoma (PTC) by histology, including 9 cases of atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS), 3 cases of follicular neoplasm/suspicious for follicular neoplasm (FN/SFN), and 46 cases of suspicious for malignancy (SM). BRAFV600E analysis detected PTC in 3 of 9 cases with AUS/FLUS, and in 31 (67.4%) of 46 cases with SM. The sensitivity of immunostaining with VE1 antibody was 62.8%(27/43) and the specificity was 91.4% (32/35). VE1 expression showed moderately concordance with the molecular mutation (κ=0.524, P<0.001).@*Conclusions@#Additional BRAFV600E detecting can improve the diagnostic efficacy for PTC in AUS/FLUS and SM. VE1 expression may be an alternative method for BRAFV600E detecting when molecular detecting is unavailable.

ABSTRACT

Objective To observe the effect of sodium acetate Ringer solution on serum levels of electrolytes, blood glucose (Glu) and lactic acid (Lac) in peri-operational stage of children undergoing neurosurgery. Methods Forty cases of children prepared to undergo neurosurgery admitted into Hunan Children's Hospital from December 2018 to April 2019 were enrolled, and according to the criteria of American Society of Anesthesiologists (ASA), they were classified into Ⅰ-Ⅱ grade. They were divided into a sodium acetate Ringer solution group and a sodium lactate Ringer solution group by random number table method, 20 cases in each group. Sodium acetate Ringer solution group was given the sodium acetate Ringer solution; sodium lactate Ringer solution group was given the sodium lactate Ringer solution, and both groups used intravenous infusion of their own respective solution at a rate of 10 mL·kg-1·h-1. Arterial blood gas detections were measured after anesthesia induction (T1), 1 hour after administration (T2), 2 hours after administration (T3) and at the end of surgery (T4); the changes in serum levels of electrolyte concentrations, blood Glu and Lac were observed in the patients of two groups. Results With the prolonged operation time, the levels of Glu and Lac in the two groups showed an increasing trend, compared with the levels at T1 and T2 , the levels were increased at T3 and T4 [the sodium lactate ringer solution group: Glu (mmol/L) were 5.85±1.02, 6.95±1.21 vs. 5.28±0.72, 5.20±0.62, and Lac (mmol/L) were 1.53±0.74, 1.91±1.41 vs. 1.23±0.71, 1.38±0.69; sodium acetate ringer solution group: Glu (mmol/L) was 5.44±0.86, 5.85±1.12 vs. 5.05±0.85, 5.14±0.74, Lac (mmol/L) were 1.58±1.31, 1.61±1.23 vs. 1.14±0.65, 1.28±0.95, all P < 0.05], the Lac and Glu levels at T4 in sodium acetate Ringer solution group were significantly lower than those in sodium lactate Ringer solution group (both P < 0.05). There were no statistically significant differences in pH value, Na+, K+ and residual base (BE) levels between the two groups at different time points (all P > 0.05). Conclusion Sodium acetate Ringer solution used in pediatric neurosurgery for more than 2 hours can reduce the blood lactic acid level without rising blood glucoselevel. Therefore, it is more suitable for infusion during pediatric neurosurgery.

ABSTRACT

Objective Children with autism spectrum disorder(ASD) who participated in the " Play-based Communication and Behavior Intervention(PCBI) " were studied in order to evaluate the impact of caregiver factors on the efficacy of the PCBI very early intervention model systematically.Methods Seventy-six children with ASD aged 8-30 months were recruited in this study at Brain Hospital Affiliated to Nanjing Medical University form December 2017 to June 2018,and they were trained for PCBI very early intervention.The Autism Treatment Evaluation Checklist (ATEC) and the Gesell Developmental Schedules were used to evaluate the efficacy of the PCBI very early intervention.Parenting Stress Index Short Form,General Self-Efficacy Scale and the self-developed Caregiver Training Course Evaluation Scale and the Homework Completion Level Scale were used to assess the level of parental stress,self-efficacy,curriculum satisfaction and acceptance.A pair of sample t-test was used to analyze the ASD symptoms,developmental level and caregiver factors of ASD children before and after intervention.Multivariate regression analysis was used to analyze the caregiver factors and the effects of PCBI very early intervention.Results (1) At the end of 12 weeks of PCBI very early intervention,the score of the ATEC (17.36 ± 15.98) was lower than that before intervention (78.43± 22.84),and the difference was statistically significant (P < 0.05);the adaptive developmental quotient (5.90 ± 15.45),the fine action developmental quotient (5.13 ± 19.89),the language developmental quotient (12.43 ± 20.60) and the personal social developmental quotient (4.79 ± 16.02) scores of the Gesell Developmental Schedules were higher than those before intervention (73.08 ± 20.54,77.33 ± 23.63,52.24 ± 19.12,71.79 ± 20.81),and the differences were statistically significant (all P < 0.05).(2) At the end of PCBI very early intervention,there was a significant decrease in the scores of Parenting Stress Index Short Form,and the differences were statistically significant (4.84 ± 14.69 vs.94.05 ± 29.67,P < 0.05).(3) Acceptance of the intervention model,and mastery of the skills in the caregiver factors had a positive predictive effect on the effect of PCBI very early intervention (t =3.068,10.468,all P < 0.05).Conclusions PCBI very early intervention can effectively reduce the parenting pressure of the caregivers,and in the PCBI very early intervention,the better the mastery of skills and the completion of homework,the better the efficacy of intervention.

ABSTRACT

OBJECTIVE@#To investigate the correlation of IgG subclasses with blood cell parameters in the patients with autoimmune hemolytic anemia (AIHA).@*METHODS@#Thirty-four patients with AIHA (except C3d types) of immune complex type (IgG+C3d) and single IgG type, including 26 cases of primary AIHA and 8 cases of secondary AIHA from December 2010 to August 2016 in our hospital were selected and enrolled in AIHA group; 30 healthy persons were selected and enrolled in healthy control group. The levels of IgG subclasses in blood plasma were detected by double antibody sandwich ELISA in healthy persons and AIHA patients, at the same time. The levels of IgG subclasses in of RBC diffuse fluid were detected as well. The relation of IgG subclass level with some parameters of blood cells was analyzed in the hight of partial parameters of blood cells in patients. The independent sample test was used for comparison of data in 2 groups, the Spearman method was used for correlation analyziz.@*RESULTS@#The average value of IgG1-4 in AIHA group was higher than that in healthy control group, there was statisticad difference between 2 groups (IgG1: t=-4.88, P0.01) the ratio pf IgG1, IgG2 and IgG3 all had the statistical differences (IgG1: t=4.03, P<0.01; IgG2: t=7.38, P<0.01; IgG3: t=3.03, P<0.01). The spearmen analysis of corrclation of IgG subclass in blood plasma of patients with partial parameters of blood cells showed that the IgG4 positivety correlated with Hb level, the RBC count and HCT (Hb: r=0.358, P<0.05; RBC: r=0.426, P<0.05; HCT: r=0.363, P<0.05); the IgG1 and IgG2 negatively correlated with WBC count (IgG1: r=0.437, P<0.05; IgG2: r=-0.487, P<0.01); the IgG2 negatively correlated with count (r=-0.436, P<0.05). The comparison of IgG subclass ratio in plasma and RBC diffuse fluid of patients showed that in addition to IgG2 (t=1.544, P>0.05), the rest IgG1, 3 and 4 all had statistical differences (IgG1: t=6.528, P<0.01; IgG3: t=-9.488, P<0.05; IgG4: t=-9.434, P<0.05).@*CONCLUSIONS@#The AIHA relates with IgG1 and IgG3, the detection of IgG subclasses may have a certain significance for studying the diagnosis, treatment and pothogenesis of AIHA.
