Abstract
Hereditary pulmonary alveolar proteinosis (hPAP) is a rare interstitial lung disease caused by mutation in CSF2RA/CSF2RB, characterized by the deposition of pulmonary surfactant due to the alveolar macrophage dysfunction. The whole lung lavage can effectively alleviate the symptoms but is associated with potential complications. Cell therapy is a novel approach with advances that provide a new therapeutic strategy for the treatment of hPAP.

Abstract
OBJECTIVE To identify and characterize read-through RNAs and read-through circular RNAs (rt-circ-HS) derived from transcriptional read-through hypoxia inducible factor 1α (HIF1α) and small nuclear RNA activating complex polypeptide 1 (SNAPC1) the two adjacent genes located on chromosome 14q23, in renal carcinoma cells and renal carcinoma tissues, and to study the effects of rt-circ-HS on biological behavior of renal carcinoma cells and on regulation of HIF1α. METHODS Reverse transcription-polymerase chain reaction (RT-PCR) and Sanger sequencing were used to examine expression of read-through RNAs HIF1α-SNAPC1 and rt-circ-HS in different tumor cells. Tissue microarrays of 437 different types of renal cell carcinoma (RCC) were constructed, and chromogenic in situ hybridization (ISH) was used to investigate expression of rt-circ-HS in different RCC types. Small interference RNA (siRNA) and artificial overexpression plasmids were designed to examine the effects of rt-circ-HS on 786-O and A498 renal carcinoma cell proliferation, migration and invasiveness by cell counting kit 8 (CCK8), EdU incorporation and Transwell cell migration and invasion assays. RT-PCR and Western blot were used to exa-mine expression of HIF1α and SNAPC1 RNA and proteins after interference of rt-circ-HS with siRNA, respectively. The binding of rt-circ-HS with microRNA 539 (miR-539), and miR-539 with HIF1α 3' untranslated region (3' UTR), and the effects of these interactions were investigated by dual luciferase reporter gene assays. RESULTS We discovered a novel 1 144 nt rt-circ-HS, which was derived from read-through RNA HIF1α-SNAPC1 and consisted of HIF1α exon 2-6 and SNAPC1 exon 2-4. Expression of rt-circ-HS was significantly upregulated in 786-O renal carcinoma cells. ISH showed that the overall positive expression rate of rt-circ-HS in RCC tissue samples was 67.5% (295/437), and the expression was different in different types of RCCs. Mechanistically, rt-circ-HS promoted renal carcinoma cell proliferation, migration and invasiveness by functioning as a competitive endogenous inhibitor of miR-539, which we found to be a potent post-transcriptional suppressor of HIF1α, thus promoting expression of HIF1α. CONCLUSION The novel rt-circ-HS is highly expressed in different types of RCCs and acts as a competitive endogenous inhibitor of miR-539 to promote expression of its parental gene HIF1α and thus the proliferation, migration and invasion of renal cancer cells.

Abstract
Background Vigabatrin (VGB) is currently the most widely prescribed first-line medication for individuals with infantile spasms (IS) and especially for those with tuberous sclerosis complex (TSC), with demonstrated efficacy. Meanwhile, its adverse events, such as vigabatrin-associated brain abnormalities on magnetic resonance imaging (MRI; VABAM), have also been widely reported. Objectives The objectives of this study were to observe the occurrences of VABAM in patients with IS caused by TSC (IST) and further explore the associated risk factors. Methods Children with IS receiving VGB were recruited from our institution; clinical, imaging, and medication data were collected. Cerebral MRI was reviewed to determine the occurrence of VABAM. Group comparisons (IS caused by TSC and other etiologies) were performed; subgroup analyses on IST were also performed. Next, a retrospective cohort study of children taking VGB was conducted to explore risk/protective factors associated with VABAM. Results The study enrolled 172 children with IS who received VGB. VABAM was observed in 38 patients (22.1%) with a peak dosage of 103.5 ± 26.7 mg/kg/day. Subsequent analysis found the incidence of VABAM was significantly lower in the 80 patients with IST than in the 92 patients with IS caused by other etiologies (10% versus 32.6%, p-value < 0.001). In subgroup analyses within the IST cohort, VABAM was significantly lower in children who received concomitant rapamycin therapy. Univariate and multivariate logistic regression analysis of the 172 IS children showed that treatment with rapamycin was the independent factor associated with a lower risk of VABAM; similar results were observed in the survival analysis. Conclusion The incidence of VABAM was significantly lower in IST patients. Further research is needed to examine the mechanisms that underlie this phenomenon and to determine if treatment with rapamycin may reduce the risk of VABAM.

Abstract
Objective: To investigate the clinical and pathological features and prognosis of patients with microfocal prostate adenocarcinoma. Methods: Clinical and pathological data of the patients diagnosed with microfocal adenocarcinoma on prostate biopsy at the West China Hospital from 2013 to 2019 were collected. Microfocal adenocarcinoma was defined as follows: Gleason score of 3+3=6, total number of the cores ≥10, number of the positive cores ≤2, and proportion of the tumor in each positive core<50%. Clinicopathological parameters, treatment plans and follow-up data were collected. Pathological information of the biopsy and radical resection specimens was used to analyze the correlation between pathological parameters in the biopsy report and adverse pathological features of radical resection specimens, including increased Gleason score, capsule invasion, positive surgical margin and perineural invasion. Results: A total of 206 cases of microfocal adenocarcinoma were diagnosed on prostate biopsies from 2013 to 2019, accounting for 6.7% of all adenocarcinoma cases. There were 139 cases of 1 positive core and 67 cases of 2 positive cores. Patients with microfocal adenocarcinoma were younger than those with non-microfocal adenocarcinoma (69 years versus 71 years, P<0.001). Compared with patients with non-microfocal adenocarcinoma, the pre-biopsy total prostate specific antigen (tPSA) and free prostate specific antigen (fPSA) levels in patients with microfocal adenocarcinoma were both lower (11.2 μg/L2 versus 23.7 μg/L2; 1.4 μg/L2 versus 3.0 μg/L2, P<0.001), the fPSA/tPSA level was higher (12.9% versus 10.7%, P<0.05), the prostate volume was larger (38.9 mL versus 34.3 mL, P<0.05), and the PSA density was lower (0.3 μg/L2 versus 0.8 μg/L2, P<0.001). 130 patients underwent radical prostatectomy, 30 patients chose active monitoring, 31 patients chose endocrine or radiation therapy, and 15 patients were lost to follow-up. Three patients in the active surveillance group underwent radical prostatectomy for disease progression after 21-39 months observation. Biochemical relapses occurred in two patients in the radical prostatectomy group. The remaining patients have no disease progression or recurrence at present. Compared with radical prostatectomy specimens, Gleason score in the biopsy material was increased in 64/115 patients (55.7%). Among resection excision specimens, 14 cases (12.2%) had extraprostatic extension (EPE), 35 cases (30.4%) had perineural invasion, and 16 cases (13.9%) had a positive margin. Univariate and multivariate analyses showed that low fPSA/tPSA ratio and 2 positive cores were independent risk factors for Gleason score increase in the radical prostatectomy specimens. A low fPSA/tPSA ratio was an independent risk factor for perineural invasion. Low fPSA/tPSA ratio and low prostate volume were associated with a positive margin in radical prostatectomy specimens. Conclusions: In this study, patients diagnosed with microfocal adenocarcinoma on prostate biopsy account for a high proportion of the patients with increased Gleason score in the radical prostatectomy specimens, and there is a certain proportion of adverse pathological features in the radical specimens. Therefore, for the patients with only a small amount of low-grade adenocarcinoma found in biopsy, PSA levels and PSA density should be taken into consideration in treatment selection.

Abstract
With the acceleration of regional economic integration, human activities have played an increasingly crucial role in regional sustainable development. In this study, MODIS remote sensing data and ecological footprint of net primary productivity (EF-NPP) were leveraged to calculate the equivalence factor and yield factor of the six major biologically productive land areas in the Pearl River Delta Urban Agglomeration. We analyzed the changes in per capita ecological footprint, per capita ecological carrying capacity, natural resource utilization efficiency and ecological moderate population from 2000 to 2020. Results showed that the per capita ecological footprint in the Pearl River Delta Urban Agglomeration continued to rise from 2000 to 2020. The ecological occupation of energy land was the highest. The ecological footprint was high in west, low in middle, and higher in northwest of the study area. The per capita ecological carrying capacity was relatively high in Zhaoqing and Jiangmen and low in Shenzhen, Dongguan, Foshan and Zhongshan. The gap between the ecological moderate population and the regional actual population widened over time, reaching 30.62 million in 2020. The regional actual population was much larger than the ecological moderate population, indicating huge population pressure. The natural resource utilization efficiency of the three main industries was high. The economic benefits created by the per capita ecological footprint increased by 36800 yuan·hm-2 during the research period, with an average annual growth rate of 1800 yuan·hm-2. The growth rate of the tertiary industry was the highest. Therefore, the results could provide reference for the study on natural resource utilization efficiency in medium and small-scale regions.

Abstract
Autism spectrum disorder (ASD), a highly hereditary and heterogeneous neurodevelopmental disorder, is influenced by genetic and environmental factors. Tuberous sclerosis complex (TSC) is a common syndrome associated with ASD. Cytomegalovirus (CMV) infection is an environmental risk factor for ASD. The similarities in pathological and mechanistic pathways of TSC and CMV intrigued us to investigate whether CMV and TSC interacted in ASD's occurrence. We detected CMV IgG seroprevalence of 308 TSC patients from our prospective cohort (September 2011 to March 2021) and 93 healthy children by magnetic particle indirect chemiluminescence immunoassay. A total of 206 TSC patients enrolled were divided into ASD and non-ASD groups, and the relationship between ASD and CMV seroprevalence was analyzed. Nested PCR and Western blot were used to detect CMV DNAs and proteins in cortical malformations of seven TSC patients with and without ASD. No difference was found in CMV seroprevalence between TSC patients and healthy children (74.0% versus 72.0%, P = 0.704). Univariate analysis showed the seroprevalence in TSC patients with ASD was higher than that in TSC patients without ASD (89.2% versus 75.1%, P = 0.063), and multifactorial analysis showed that CMV seroprevalence was a risk factor for ASD in TSC patients (OR = 3.976, 95% CI = 1.093 to 14.454). Moreover, CMV was more likely to be detected in the cortical malformations in TSC patients with ASD but not in those without ASD. The findings demonstrated that CMV may increase the susceptibility of TSC to ASD. IMPORTANCE CMV is an environmental risk factor for ASD, but its role in syndromic autism with known genetic etiology has been rarely studied. The pathogenesis of ASD is related to the interaction between environmental and genetic factors. This study demonstrated that CMV can contribute to the occurrence of ASD related to TSC, a common genetic syndrome associated with ASD. Our findings provided support for the theory of gene-environment interaction (G × E) in pathogenesis of ASD and a new perspective for the prevention and therapy for TSC related ASD.

Abstract
PURPOSE There was no evidence whether the mammalian/mechanistic target of rapamycin pathway hyperactivation and long-term use of mTOR inhibitors have any effects on the physical development of children. The aim was to evaluate these effects by comparing the physical development of children with TSC and normal children. METHODS A total of 120 eligible children were enrolled. They were administered sirolimus and followed for at least 12 months. Height, weight, BMI and lipid metabolism index were collected during treatment. Pearson's chi-square and Fisher's exact test were used for comparison of proportions of patients exhibiting normal and abnormal physical growth before and after 1 year of treatment. Logistic regression was used to evaluate the influence of age, sex and abnormal lipid metabolism on the increased BMIs of TSC patients after treatment. RESULTS Most of the enrolled TSC children were in the normal height, weight and BMI ranges at baseline (91.7%, 95.8% and 78.3%, respectively). Most remained in the normal height, weight and BMI ranges after 1 year of sirolimus treatment (94.2%, 95% and 76.7%, respectively). There was no significant difference in the proportion of physical development before and after treatment (p > 0.05). Thirty-eight (38/106, 35.8%) patients had increased BMIs after 1 year of treatment, but there was no significant correlation between age, sex and lipid metabolism and increased BMI. CONCLUSIONS Overactivation of the mTOR pathway and long-term administration of sirolimus does not affect the physical development of children with TSC.

Abstract
OBJECTIVE To evaluate whether sirolimus treatment could relieve the later burden of new-onset seizures in patients with tuberous sclerosis complex (TSC) prior to epilepsy. METHODS A real-world matched case-control study was nested in another registry cohort study. Infants with TSC (<12 months old) without seizures whose parents agreed on sirolimus treatment for other symptoms were eligible for inclusion to the early sirolimus (ES) group. These patients were enrolled from 2015 to 2018. Controls in the late sirolimus (LS) group were matched from the registry cohort database for 2015-2018. Age and genotype were used as the initial stratifying criteria and other symptoms as the greedy matching criteria at a matching ratio of 1:4. None of the preventive drugs were introduced before seizure onset or before 2 years of age in the LS group. Both groups were followed up until June 2020. The primary objective was a comparison of the characteristics of the first seizure between the two groups. The secondary objective was the assessment of the final seizure status at the endpoint. RESULTS There were 42 and 168 patients with TSC in the ES and LS groups, respectively. Early sirolimus treatment significantly reduced the seizure onset, especially in the patients aged <6 months. The mean onset-age was significantly delayed by sirolimus treatment (11.34±7.93 months vs. 6.94±6.03 months, P<0.001). The subtype of seizures that benefited the most was spastic (onset) seizures (all were infantile spasms) [5/42 (11.90%) vs. 73/168 (43.45%), P<0.001]; these seizures were either eliminated or alleviated. The sirolimus treatment addition prior to seizures was more effective than its addition after seizures in reducing drug-resistant epilepsy [10/42 (23.81%) vs. 70/147 (47.62%), P=0.004]. CONCLUSION Early sirolimus treatment for TSC effectively modified the disease by preventing infantile spasms, delaying seizure onset, and relieving its severity. The anti-epileptogenic effect of sirolimus may be time- and dose-dependent.

Abstract
Objective: To use Meta analysis to understand the prevalence of the heritability of body mass index (BMI) in twins. Methods: All studies on the heritability of the twins' BMI published before December 31, 2020 were retrieved through the China National Knowledge Network, Wanfang, VIP, PubMed and Web of Science databases. The literature quality was evaluated by using Joanna Briggs Institute Critical Appraisal tools. Stata 16.0 was used to perform subgroup analysis on the outcome indicators (heritability, 95%CI) to explore the source of heterogeneity. The local weighted regression method was used to fit the trend of heritability with age. The publication bias test and the sensitivity analysis of included literatures were also performed by using Stata 16.0. Results: A total of 10 articles meeting the inclusion and exclusion criteria were included with 79 twins' independent estimates of heritability for BMI. Meta-analysis showed that the combined value of BMI heritability was 0.69 (95%CI: 0.65-0.71), the combined value of BMI (0.68, 95%CI: 0.65-0.70) in males was lower than that (0.70, 95%CI: 0.68-0.72) in females. The heritability of BMI (0.72, 95%CI: 0.68-0.76) in childhood and adolescence was higher than that (0.68, 95%CI: 0.66-0.70) in adulthood. The gender specific difference in BMI heritability in twins ≤18 years old was even greater, which was lower in males (0.68, 95%CI: 0.61-0.76) than in females (0.75, 95%CI: 0.69-0.81). The heritability increased with age in childhood, reached peak at about 18 years old, and then slowly decreased with age. Conclusions: The heritability of BMI varied with population characteristics, especially age and gender. In view of the high estimated value of BMI heritability in female children and adolescents, more attention should be paid to the start time of health intervention.

Abstract
Objective: To quantitatively analyze the effects of population aging and other risk factors on the burden of atherosclerosis cardiovascular disease (ASCVD) in China from 1990 to 2019. Methods: Disability adjusted life years (DALY) and age-standardized rates obtained from the Global Burden of Disease Study 2019 (GBD2019) were used to describe the temporal trend of a burden on ASCVD. And a decomposition method established by Gupta was applied to quantify the burden related to population growth, aging, age-specific prevalence, and the severity of the disease. Results: In 2019, 61.00% of the burden of cardiovascular disease in China was caused by ASCVD. The DALY of ischemic heart disease increased by 133.66% compared with that in 1990, with 29.57% of the increase attributed to population growth, 108.74% due to population aging, and 8.87% due to the rise of age-specific prevalence and -13.53% benefited from changes in disease severity. The DALY of ischemic stroke increased by 138.64% compared with 1990, and the proportions attributable to the above four parts were 30.95%, 123.38%, 55.80%, and -71.49%, respectively. Hypertension remained the leading risk factor for ASCVD in 2019, followed by high LDL cholesterol. The age-standardized DALY rate attributable to drinking had the most significant increase (486.01%) from 1990, with an average annual growth of 10.93%. Conclusions: Aging population seems responsible for the main reason for the considerable increase in the burden of ASCVD in China. Still, the adverse trends of other avoidable risk factors, especially metabolic risk factors, can not be ignored.

Abstract
Temperature-induced structural variations of retrograded starch gel during long-term storage were investigated in a real food system (wet starch noodles). Fresh starch noodles presented a B-type XRD pattern containing 8.82% crystallinity and 16.04% double helices. In the first 2 weeks, double helices of starch chain formed long-range ordered structure leading to increased crystallinity, and such structural transformation was positively correlated with increasing storage temperature (from 4 °C to 35 °C) and storage time. However, with the extension of storage time to 12 weeks, the disorganization of supra-molecular structure was likely to be observed by decreased crystallinity, double helix and water mobility. Besides, we propose that the area and intensity of Raman band at 2910 cm-1 can be a good indicator for evaluating perfection of crystallinity in starch noodles. These results contributed to a better understanding of mechanisms underlying molecular order changes of retrograded starch gel product during long-term storage.

Abstract
OBJECTIVES To investigate the efficacy and safety of sirolimus in the treatment of cardiac rhabdomyomas associated with tuberous sclerosis complex and the specific benefits in different subgroups. STUDY DESIGN The study was a prospective cohort and self-controlled case series study. Based on the prevalence of cardiac rhabdomyoma at different ages, we estimated the natural tumor disappearance rate. The subgroup analysis was done by Cox regression. Self-controlled case series method was used to assess the magnitude and duration of the drug effect. Adverse events were described. RESULTS A total of 217 patients were included in the cohort study. Tumor disappearance rate was higher in younger age groups (hazard ratio = 0.99, P = .027) and female patients (hazard ratio = 2.08, P = .015). The age-adjusted incidence ratio showed that the disappearance of rhabdomyomas between 3 and 6 months was more related to sirolimus. Adverse events were observed 60 times in 42 of 217 children, mainly stomatitis. CONCLUSIONS Sirolimus can increase the disappearance rate of cardiac rhabdomyoma in the tuberous sclerosis complex population. Efficacy varies by sex and age: female and younger patients have higher tumor disappearance rate. Sirolimus is well-tolerated.

Abstract
Cooking performance, micro- and molecular structure, storage stability and shelf-life prediction of high-moisture wet starch noodles (SN) were investigated. SEM images revealed that compared to dried SN, cooked wet SN had more evenly honeycomb-like network with smaller size of pores, indicating stronger interaction among molecules and causing favorable cooking performance. XRD and ATR-FTIR results evidenced that wet SN contained more complete crystallites and higher proportion of crystalline region. During storage, the quality decay of wet SN was mainly associated to the increment of total aerobic viable count (TAVC), titrable acidity and amylase, as well as the decreased textural hardness, overall acceptability and lightness. Based on TAVC, titrable acidity and overall acceptability, predicted shelf-life of vacuum-packed wet SN at 25 °C was 15.31, 21.54 and 16.65 weeks respectively, with relative error all within 20%, proving that the validated model could be an effective tool for monitoring the shelf-life of wet SN.

Abstract
Objective: To investigate the clinicopathological and molecular characteristics of the epithelioid glioblastoma (eGBM) with BRAF V600E mutation. Methods: Sixteen cases of eGBM with BRAF V600E mutation diagnosed at the West China Hospital of Sichuan University, China from 2012 to 2019 were collected. Their clinicopathological and molecular characteristics were analyzed. Results: The range of patients' age was from 7 to 61 years (median 31.5 years). There were 4 males and 12 females, with a male to female ratio of 1∶3. Eleven cases were newly diagnosed eGBM and five cases had a previous history of astrocytomas. Most of the tumors were located in the cerebral hemisphere, often in the frontal lobe, with an average diameter of 4.6 cm (2.0-8.0 cm). The tumors were composed of relatively uniform, closely packed epithelioid cells, some showing discohesion, with distinct cell membrane, eosinophilic cytoplasm, eccentric nuclei, distinct nucleoli and mitotic activity. Palisaded/coagulative necrosis was seen in all cases. Glomerular microvascular proliferation was seen in most of the cases, while mono-or multi-nucleated tumor giant cells were seen in some cases. Focal sarcomatoid area was seen in 2 cases, and focal pleomorphic xanthoastrocytoma (PXA)-like area was seen in 3 cases. Immunohistochemistry showed variable positivity for GFAP, Olig2 and p53. The median Ki-67 index was 30% (10%-50%). Only one case lost ATRX protein expression. Sanger sequencing identified the BRAF V600E mutation in all sixteen patients. Five cases also had mutations in the TERT gene promoter. No IDH1 (R132) or IDH2 (R172) mutation was detected. Surgical resection of the tumors was performed for all patients, and 3 patients also received adjuvant radiotherapy and chemotherapy. Follow-up data were available for 15 patients, with a follow-up time of 1-89 months (median 10 months). Among the 15 patients, 7 patients died of disease and another 5 patients had recurrences. The overall survival time of the patients under 35 years of age was significantly longer than that of the patients aged 35 years or older (P=0.014), but their progression-free survival was not statistically different (P=0.232). Conclusions: eGBM with BRAF V600E mutation is more commonly detected in young women than other the populations (i.e. elderly or male). The epithelioid morphology should include rhabdoid meningioma, anaplastic PXA, atypical teratoid/rhabdoid tumor, metastatic tumors, and melanoma in its differential diagnosis. PXA-like area is observed in some eGBM cases, suggesting a relationship of these two types of tumor. eGBM is a high-grade malignant tumor and most of the cases show recurrences or deaths in a short-period time. The younger patients have a relatively better prognosis than the older ones.

Abstract
Objective: To preliminarily explore the treatment effect of nivolumab on Chinese non-small-cell lung cancer (NSCLC) patients with brain metastases, and further enrich the evidences of programmed death-ligand 1 (PD-1) monoclonal antibody in the treatment of NSCLC patients with brain metastases. Methods: The clinical and pathological data of 22 NSCLC patients with brain metastases treated with nivolumab were collected. The electronic imaging data were collected to confirm the treatment effect and time point of disease progression, and the survival data of the patients were obtained through follow-up. Results: Twenty-one patients were evaluated for the intracranial treatment effect. The intracerebral objective response rate (IORR) was 28.6%, the intracranial disease control rate (IDCR) was 47.6%. The median intracranial progression-free-survival (iPFS) of all the 22 patients was 5.2 months. Both the 1-year and 2-year survival rates were 56.7%. Conclusions: The treatment effect of PD-1 monoclonal antibody on NSCLC patients with brain metastases is similar as those without brain metastases.

Abstract
Developmental and epileptic encephalopathy (DEE) is a severe encephalopathy in infants and early childhood. In this study we reported a recurrent de novo variant (c.3985C>T, p.R1330W) in HECW2 (HECT, C2 and WW domain containing E3 ubiquitin protein ligase 2) (MIM# 617245) identified by screening 240 patients with DEE and summarized clinical features of published DEE patients with HECW2 variants. Functionally, transcriptional knockdown of zebrafish hecw2a led to early morphological abnormalities in the brain tissues. These results suggest a potential functional link between HECW2 dysfunction and brain development.

Abstract
OBJECTIVE Tuberous sclerosis complex (TSC) is a rare autosomal dominant genetic disease with many manifestations, and it involves any organ. In this study, we report a TSC patient with new type skin lesions. METHODS A 7-month-old TSC boy with multiple cutaneous nodules was admitted in our hospital. We collected the clinical data of the patient. We performed biopsy of cutaneous nodules and whole-exome sequencing in both paraffin block tissue and blood samples. RESULTS The patient presented with a 2 month history of gradual growth multiple cutaneous nodules. He had cardiac rhabdomyoma, subependymal giant cell astrocytoma (SEGA) and hypomelanotic macules. The pathological finding of cutaneous nodules was consistent with juvenile xanthogranuloma (JXG). After 3 months of sirolimus treatment, the multiple nodules disappeared. The whole-exome sequencing identified TSC1 (c.2356C > T, p.R786*) mutation in both paraffin block tissue and blood samples. We overturned the original pathological diagnosis and finally identified JXG as a new type of skin lesions in TSC. CONCLUSION This is the first report on the occurrence of JXG skin lesions in TSC patient. Genetic testing is necessary in JXG. These findings expand the phenotype of skin in patients with TSC and contribute to the elucidation of JXG pathogenesis and treatment.

Abstract
Collagen type IV, alpha-1 (COL4A1) variants can cause cerebrovascular diseases, such as porencephaly and cerebral hemorrhage, in addition to other autosomal dominant hereditary diseases. Patients with COL4A1 variants can present with epilepsy, most commonly focal epilepsy. In this paper, we present five patients, three of whom were examined by the authors, and two who were previously reported. Clinically, these five patients were characterized by the presence of West syndrome (WS), periventricular leukomalacia (PVL), and microcephaly, but none had a history of premature birth or hypoxic ischemic encephalopathy (HIE). Genetic testing results indicated that all patients had heterozygous variants of COL4A1. Genetic testing for the COL4A1 variants should be considered when a patient without a history of prematurity or HIE develops WS with PVL and microcephaly.

Abstract
Objective: To investigate the efficacy and safety of rapamycin in children with tuberous sclerosis complex (TSC) associated renal disease. Methods: A prospective self-control study was conducted. The clinical data of 92 children diagnosed with tuberous sclerosis complex associated kidney disease at the People's Liberation Army General Hospital from January 2011 to January 2019 were collected. The long-term rapamycin treatment for all patients initiated at 1 mg/(m(2)·d), which was gradually adjusted to reach a blood concentration of 5-10 μg/L. The changes of the maximum diameter of renal lesions in children after rapamycin treatment were observed and analyzed with Wilcoxon test. Results: Ninety-two children, including 52 males and 40 females, who met the criteria were analyzed. Sixty patients had only renal angiomyolipoma(RAML), while 24 patients had only multiple renal cysts(MRC), and 8 patients had both lesions. The age of TSC diagnosis was 16.0 (7.0, 42.0) months, and the age of initial treatment with rapamycin was 63.5 (21.0, 103.0) months. The follow-up lasted for 12.0 (4.0, 23.0) months. Sequencing of TSC1 and TSC2 genes was performed in 54 children with TSC, including 3 patients (6%) with mutations in TSC1 gene and 51 patients (94%) with mutations in TSC2 gene. The maximum RAML diameter before treatment was 7.0 (4.0, 9.0) mm. The best effect reached at 3 months of treatment, with the diameter of 4.0 (0,7.0) mm. The maximum diameters at 6 months, 1 year and 1-2 years were 5.0 (0,9.8) mm, 5.0 (1.5, 8.5) mm, 5.5 (3.0, 9.0) mm, respectively, and were significantly different from the baseline (Z=-2.404,-2.350,-2.750,P=0.016,0.019,0.006, respectively). The maximum diameter after 2-3 years, and ≥3 years were 5.0 (3.9,7.0) mm and 6.0 (1.0, 11.0) mm, without significant difference from the baseline (Z=-0.856,-0.102,P=0.393,0.919, respectively).The maximum diameters of MRC after 3 months, 6 months, 1 year,1-2 years, 2-3 years, and ≥3 years were 11.0 (5.0, 14.0) mm,3.0 (0.0,11.0) mm,5.0 (0,21.0) mm,0 (0,14.0) mm,0 (0,10.0) mm, and 0 (0,18.3) mm, respectively, but were not significantly different rom the baseline (7.0 (5.0, 15.7) mm)(Z=-0.944,-1.214,-1.035,-1.896,-1.603,-1.214,P=0.345,0.225,0.301,0.058,0.109,0.225, respectively).Twenty-nine patients (32%) had oral ulcers during the entire treatment period, and no serious adverse reactions were observed. Conclusions: Rapamycin could decrease the diameter of TSC-related RAML, but could not inhibit the growth of cysts. It is well tolerated in the treatment of renal diseases associated with tuberous sclerosis complex.

Abstract
Objective: To investigate the clinical effects of first generation epithelial growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) compared with platinum-based chemotherapy as first-line therapy in advanced lung adenocarcinoma patients with uncommon EGFR mutations. Methods: Clinical data of 4 276 patients diagnosed as advanced lung adenocarcinoma (ⅢB/Ⅳ) underwent EGFR gene detection at the Affiliated Cancer Hospital of Zhengzhou University from January 2012 to February 2018 were collected and 99 cases with uncommon EGFR mutations were selected. The clinical pathological features, treatment outcomes, treatment options and prognosis after first-line treatment of the 99 cases were analysed and compared with other patients with common EGFR mutations. Results: The objective response rates of patients with uncommon EGFR mutations receiving EGFR-TKIs or platinum-based chemotherapy were 33.0% and 27.1%, respectively. The disease control rates were 76.5% and 87.5%, respectively. The progression-free survival (PFS) of patients treated with EGFR-TKIs was 7.2 months, significantly superior than 4.9 months of patients receiving chemotherapy (P=0.009). The overall survival of patients treated with EGFR-TKIs was 14.3 months, significantly worse than 20.7 months of patients receiving chemotherapy (P=0.034). Multivariate analysis showed that distant metastases (P=0.001) and smoking history (P=0.013) were independent prognostic factors for OS of lung adenocarcinoma patients with EGFR uncommon mutations. Conclusions: Compared with chemotherapy, the usage of first generation of EGFR-TKIs as first-line therapy can improve the short-term efficacy of advanced lung adenocarcinoma patients with EGFR uncommon mutations. However, platinum-based chemotherapy shows a longer overall survival.

Abstract
Background The diagnosis of paroxysmal events in infants is often challenging. Reasons include the child’s inability to express discomfort and the inability to record video electroencephalography at home. The prevalence of mobile phones, which can record videos, may be beneficial to these patients. In China, this advantage may be even more significant given the vast population and the uneven distribution of medical resources. Objective The aim of this study is to investigate the value of mobile phone videos in increasing the diagnostic accuracy and cost savings of paroxysmal events in infants. Methods Clinical data, including descriptions and home videos of episodes, from 12 patients with paroxysmal events were collected. The investigation was conducted in six centers during pediatric academic conferences. All 452 practitioners present were asked to make their diagnoses by just the descriptions of the events, and then remake their diagnoses after watching the corresponding home videos of the episodes. The doctor’s information, including educational background, profession, working years, and working hospital level, was also recorded. The cost savings from accurate diagnoses were measured on the basis of using online consultation, which can also be done easily by mobile phone. All data were recorded in the form of questionnaires designed for this study. Results We collected 452 questionnaires, 301 of which met the criteria (66.6%) and were analyzed. The mean correct diagnoses with and without videos was 8.4 (SD 1.7) of 12 and 7.5 (SD 1.7) of 12, respectively. For epileptic seizures, mobile phone videos increased the mean accurate diagnoses by 3.9%; for nonepileptic events, it was 11.5% and both were statistically different (P=.006 for epileptic events; P<.001 for nonepileptic events). Pediatric neurologists with longer working years had higher diagnostic accuracy; whereas, their working hospital level and educational background made no difference. For patients with paroxysmal events, at least US $673.90 per capita and US $128 million nationwide could be saved annually, which is 12.02% of the total cost for correct diagnosis. Conclusions Home videos made on mobile phones are a cost-effective tool for the diagnosis of paroxysmal events in infants. They can facilitate the diagnosis of paroxysmal events in infants and thereby save costs. The best choice for infants with paroxysmal events on their initial visit is to record their events first and then show the video to a neurologist with longer working years through online consultation.

Abstract
Background Posterior reversible encephalopathy syndrome (PRES) is a complication that occurs during various diseases’ treatment. Imaging examination is the gold standard for diagnosis. PRES frequently occurrence in patients with hematological malignancies results in poorer prognosis and higher mortality. We aim to establish a practical and operable scale for early prediction, assessment of the severity of the Posterior Reversible Encephalopathy Syndrome, and timely intervention for better prognosis. Methods The scale designed by reviewing the literature and by referring to clinical practice. We assessed the reliability and validity of the scale. Scale-based assessment of children undergoing chemotherapy for acute lymphoblastic leukemia conducted as early warning and intervention for those who may have PRES. Results Establishment of Posterior Reversible Encephalopathy Syndrome early warning scoring (PEWS) scale included three parts, as follows: (1) risk factors, including underlying disease, hypertension, Infection, and drug toxicity; (2) clinical features, including high cranial pressure, visual symptoms, seizure, and disturbance of consciousness; and (3) EEG features, including slow wave and epileptiform discharges. Utility assessment of PEWS scale showed that in 57 patients with acute lymphoblastic leukemia, 54 scored less than 10 and none of them detected as PRES. The other two had scores of 12 and 13 both diagnosed with PRES by brain MRI scan. Conclusions PEWS scale can predict PRES early. PRES was highly suspected when the score was 10 points and more. Thus, prophylactic intervention can give to improve the prognosis of PRES.

Abstract
Objective: To investigate the status and prognostic significance of TERT and IDH1/2 genes mutations in diffusely infiltrating gliomas. Methods: Hot spot mutations of TERT and IDH1/2 genes were detected by DNA sequencing in 236 cases of gliomas at West China Hospital from 2012 to 2016, including pilocytic astrocytoma (WHO grade Ⅰ, 16 cases), diffuse astrocytoma and oligodendroglioma (WHO grade Ⅱ, 89 cases), anaplastic astrocytoma and oligodendroglioma (WHO grade Ⅲ, 72 cases) and glioblastoma (WHO grade Ⅳ, 59 cases). The prognostic significance of TERT and IDH1/2 hot spot mutations was evaluated. Results: No IDH or TERT mutations were detected in pilocytic gliomas. TERT promoter mutation frequency was higher in patients aged ≥40 years(60.8%, 93/153) than in patients aged <40 years (32.8%, 22/67; P<0.01). TERT promoter mutation rate was also significantly higher in oligodendroglioma (87.5% , 56/64) than that in astrocytoma(37.8%, 59/156; P<0.01). Young age (<40 years), oligodendroglioma and IDH1 mutation were favorable prognostic factors for diffusely infiltrating astrocytic and oligodendroglial tumors. TERT mutation alone was not of prognostic significance. Diffusely infiltrating astrocytic and oligodendroglial tumors were divided into four molecular subtypes according to TERT and IDH1 mutation status: IDH(+ )/TERT(+ ), IDH(+ )/TERT(-), IDH(-)/TERT(-) and IDH(-)/TERT(+ ). There was significant prognostic difference among the 4 subtypes. Conclusions: Combined IDH and TERT gene mutation analysis may be useful for prognostic subgrouping. Notably, IDH1 wild-type cases can be further subdivided into TERT(+ ) or (-) subgroups with significant prognostic difference.

Abstract
PURPOSE Tuberous sclerosis (TSC) is an autosomal dominant inherited disease caused by mutations in the TSC1 or TSC2 gene and results in the over-activation of the mammalian target of the rapamycin (mTOR) signaling pathway. Rapamycin, an mTOR inhibitor, is clinically used to treat hamartomatous lesionsas in TSC and its effect on controlling epilepsy is also reported in many studies. This study aims to evaluate the risk factors of pharmacoresistant epilepsy in patients with TSC receiving long-term rapamycin treatment. METHOD A total of 108 patients with TSC taking rapamycin for over 1 year were enrolled in this study. Factors that might influence seizure control were statistically analyzed by multiple factor analysis. A subgroup analysis was also conducted to access the relationship between calcified epileptic foci and pharmacoresistant epilepsy. (Clinical trial registration number: ChiCTR-OOB-15006535(2015-05-29)). RESULTS Seizure was controlled in 53 patients but was not managed in 55 patients considered to be drug resistant. Logistic regression analysis showed that calcification in the cerebral parenchyma was a risk factor of pharmacoresistant epilepsy [P = 0.006, odds ratio (OR) = 4.831 (1.577, 14.795)]. Fifteen of 17 patients with calcified epileptic foci suffered from pharmacoresistant epilepsy (88.2%). Seizures in patients with calcified epileptic foci were probably pharmacoresistant (P = 0.010). CONCLUSION Calcification in epileptic foci strongly indicates pharmacoresistant epilepsy in patients with TSC even when treated with appropriate anti-epilepsy drugs (AEDs) and rapamycin. Calcification can be used to evaluate pharmacoresistant epilepsy in patients with TSC.

Abstract
Background In previous study, we have found intermittent oral levetiracetam (LEV) can effectively prevent recurrence of febrile seizure (FS). This study aimed to analyze the effects of the preventive on the patients with frequent FS accompanied with epileptiform discharge. Methods Patients with frequent FS were assigned to undergo Electroencephalogram (EEG). At the onset of fever, the patients who presented epileptiform discharge were orally administered with LEV with a dose of 15–30 mg/kg per day twice daily for 1 week, thereafter, the dosage was gradually reduced until totally discontinued in the second week. The seizure frequency associated with febrile events and FS recurrence rate during a 48-week follow-up were analyzed. Results among the 19 patients presented epileptiform discharge on EEG, 31.58% (6 of 19) had complex FS, 68.42% (13 of 19) had simple FS. Up to 57.89% (11 of 19) had a family history of seizure disorder and 36.84% (7 of 19) had a family history of FS in first-degree relatives. 42.11% (8 of 19) happened the first FS episode at the age < 18 months. 36.84% (7/19) presented generalized spikes, 63.16% (12/19) showed focal spikes. During the 48-week follow-up period, the patients experienced 26 febrile episodes, none of them presented seizure recurrence. Conclusion Intermittent oral LEV can prevent the seizure recurrence of FS accompanied with epileptiform discharge in 48-week. However, further randomized controlled trials should be conducted. Trial registration ChiCTR-IPR-15007241; Registered 1 January 2014 - Retrospectively registered.

Abstract
RATIONALE Blue rubber bleb nevus syndrome (BRBNS) is a rare disease characterized by multiple venous malformations. The gastrointestinal bleeding and secondary iron deficiency anemia are the most common complications. There are currently no effective treatments for BRBNS. Here, we report a case of successful treatment with a small dose of sirolimus of a BRBN patient with a de novo gene mutation. PATIENT CONCERNS A 12-year-old female was admitted to our hospital with multiple hemangiomas for 12 years. The patient often displayed melena; she recently received transfusion of 2 units of red blood cells once every 2 weeks. Multiple fist-sized hemangiomas were piled up on both sides and back of the neck, and were also noted on the arms, legs, chest, back, and on the tip of the tongue. The laboratory findings demonstrated severe anemia. Blood sample sequencing detected a heterozygous de novo mutation c.2545C > Tin the TEK gene. DIAGNOSES Based on these findings, final diagnosis of Blue rubber bleb nevus syndrome (BRBNS) was made. INTERVENTIONS After the diagnosis, low-dose sirolimus was orally administered. OUTCOMES The patient's hemoglobin was increased after treatment with sirolimus for 1 month. Since the initial treatment with sirolimus, she had not received any blood transfusions. The skin and mucosal hemangioma decreased significantly, and new digestive tract hemorrhage, muscle hematoma, or adverse drug reactions were not observed. LESSONS we report a case of a mutation in exon 15 of the TEK gene leading to BRBN. It was successfully treated with a small dose of sirolimus as an alternative to blood transfusion in order to save the of BRBN patient's life.

Abstract
Mouse VD-hemopressin(α) (VD-Hpα) is an undecapeptide that selectively activates CB1 cannabinoid receptor in in vitro functional tests, and exerts CB1-mediated central antinociception in the mouse tail-flick assay. The aim of the present study was to further investigate the analgesic properties of supraspinal mouse VD-Hpα in a range of preclinical pain models. Our results indicated that the classical cannabinoid agonist WIN 55,212-2 produced supraspinal analgesia in preclinical pain models, which was selectively antagonized by the CB1 antagonist/inverse agonist AM251, but not by the CB2 antagonist AM630. In contrast, in post-operative pain model and phase I of formalin test, intracerebroventricular administration of mouse VD-Hpα induced dose-related analgesia in mice, which were markedly reduced by pretreatment with the CB1 neutral antagonist AM4113, but not AM251, AM630 and the selective antagonists of opioid and Transient Receptor Potential Vanilloid Type 1 (TRPV1) receptors. Furthermore, in the acetic acid-induced visceral pain model, supraspinal administration of mouse VD-Hpα dose-dependently produced analgesic activities and the effects were significantly antagonized by both AM4113 and the TRPV1 receptor antagonist SB366791, but not AM251, AM630 and naloxone. In addition, central injection of mouse VD-Hpα did not have significant effect in phase II of formalin test. Taken together, the present work suggests that the CB1 receptor peptidic agonist mouse VD-Hpα produces supraspinal analgesia in preclinical pain models via a novel CB1 receptor-mediated mechanism, in a manner pharmacologically dissociable from WIN 55,212-2. In addition, TRPV1 receptor might also be involved in mouse VD-Hpα-induced analgesia in a visceral pain model.

Abstract
Mental retardation (MR) is one of the most common cognitive comorbidities in children with tuberous sclerosis, and there are enormous studies about its risk factors. The genetic difference and the severity of epilepsy are the two main factors, but their weight in the occurrence of MR is still unclear. Two hundred twenty-three patients with tuberous sclerosis who received intelligence assessment, genetic mutation analysis, and the epilepsy severity assessment were included in our study. Genotype-neurocognitive phenotype correlations and epilepsy-neurocognitive phenotype correlations were analyzed by binary logistic regression analysis. No statistical significant result was found on genotype-neurocognitive phenotype correlations, which contrasted the previous report. The prevalence of MR was 50.0% for the patients with tuberous sclerosis complex-1 (TSC1) mutation, 54.5% for TSC2 (p=0.561), 54.7% for patients with protein-truncating (PT) and 50.0% for patients with nontruncating (NT) (p=0.791), and 54.3% for patients with family history and 53.7% for patients without family history (p=0.748). Statistical significant results were found on epilepsy-neurocognitive phenotype correlations, both on E-chess score (p=0.01) and the occurrence of infantile spasms (p=0.014), which was consistent to the previous study. For children with tuberous sclerosis, instead of genetic factors, epilepsy may play the main role for the presence of mental retardation. Patients with mental retardation tend to have earlier seizure attack, take more AEDs, have more seizure types, and have higher seizure frequency. Among the four cognitive functions in Denver II, social ability and language ability are more vulnerable to be influenced than fine and gross motor ability.

Abstract
Hemopressin and related peptides have shown to function as the endogenous ligands or the regulator of cannabinoid receptors. Moreover, hemopressin and its truncated peptides were also reported to produce a slight modulatory effect on opioid system. In the present work, based on the amino acid sequence analyses of hemoglobin subunit α, rat VD-hemopressin(α) [(r)VD-Hpα] was predicted as a cannabinoid peptide derived from rat α-hemoglobin. Furthermore, (r)VD-Hpα was synthesized and characterized in a series of in vitro and in vivo assays. Our results demonstrated that (r)VD-Hpα induced neurite outgrowth in Neuro 2A cells via CB1 receptor. In the tail-flick assay, (r)VD-Hpα dose-dependently exerted central antinociception through CB1 receptor, but not CB2 and opioid receptors. In mice, supraspinal administration of (r)VD-Hpα produced dose-dependent hypothermia, which was partially reduced by the CB1 receptor antagonist AM251, but not by the antagonists of CB2 and opioid receptors. In addition, (r)VD-Hpα caused hypoactivity after intracerebroventricular injection, and this effect was insensitive to the antagonists of cannabinoid and opioid receptors. Further assessment of the side-effects demonstrated that (r)VD-Hpα evoked the limited effects on gastrointestinal transit at antinociceptive doses, but repeated i.c.v. injection of (r)VD-Hpα induced development of antinociceptive tolerance. Taken together, these data suggest that the predicted peptide (r)VD-Hpα produces antinociception, hypothermia and hypoactivity via different pharmacological mechanisms, at least partially, which may offer an attractive strategy for separating cannabinoid analgesia from hypoactivity. Moreover, it implies that (r)VD-Hpα has therapeutic potential in pain management with limited side-effects.

Abstract
We investigated the clinical phenotypes and genetic mutations in Chinese children diagnosed with tuberous sclerosis complex (TSC). Sequencing of TSC1 and TSC2 genes was performed in 117 children with TSC and their parents. Association of TSC gene mutations with clinical manifestations was investigated. All gene mutations were heterozygous including in 16 patients (13.7%) with mutations in TSC1 gene and 101 patients (86.3%) with mutations in TSC2 gene. Among the 16 patients with TSC1 gene mutations, 15 different types of mutations were found, which included 5 novel mutations; all patients had skin manifestations and epilepsy. Among the 101 patients with TSC2 mutations, 85 different types of mutations were found, which included 25 novel mutations; 97 patients (96.0%) had skin manifestations; 97 (96.0%) had epilepsy; 74 (73.3%) had intellectual disability and 25 patients (24.8%) were autistic. The clinical phenotype of the 14 children with familial TSC was more severe than that of their parents.

Abstract
Objective: To investigate the status of immunization of National Immunization Program (NIP) and its adverse reaction rate in children with tuberous sclerosis. Method: Questionnaire survey was adopted to identify the vaccination coverage and its adverse events; 72 cases of children with tuberous sclerosis and 78 normal controls (healthy children completing age-appropriate NIP) admitted to Chinese People's Liberation Army General Hospital from December 2014 to November 2015 were involved into this study. Result: The age-appropriate NIP coverage rate of tuberous sclerosis was 36%(26/72). The coverage rate of bacillus calmette-guerin (BCG), hepatitis B vaccine 1st to 3rd doses (HepB1-3), oral poliovaccine 1st dose (OPV1), diphtheria, pertussis and tetanus 1st dose (DPT1), DPT1-3, meningococcal polysaccharide vaccine group A (MPVA), measles amd rubella vaccine/measles vaccine 1st dose (MRV/MCV1), and Japanese encephalitis vaccine 1st dose (JEV1) were 100%(72 cases), 75%(51 cases), 97%(66 cases), 91%(62 cases), 82%(56 cases), 66%(45 cases), 69%(42 cases), and 61%(37 cases) respectively. The reasons why the children did not complete the vaccination plan were that parents were concerned about vaccination-induced seizures or seizures had not been controlled. Among 72 children with TSC, the rate of adverse events or suspected adverse events after vaccination was 17% (12 cases), which was higher than the normal control children (2 cases, 3%) (χ2=8.799, P<0.05). The main adverse events were seizure events, which accounted for 92%(11 cases). Conclusion: The age-appropriate NIP coverage rate among children with tuberous sclerosis is low. The high incidence of adverse events may be associated with a fact that there are some nervous system abnormalities in cases with tuberous sclerosis. TSC children vaccination is relatively safe, with no serious adverse events.

Abstract
Neurite outgrowth is an important process in neural regeneration and plasticity, especially after neural injury, and recent evidence indicates that several Gαi/o protein-coupled receptors play an important role in neurite outgrowth. The neuropeptide (NP)FF system contains two Gαi/o protein-coupled receptors, NPFF1 and NPFF2 receptors, which are mainly distributed in the central nervous system. The aim of the present study was to determine whether the NPFF system is involved in neurite outgrowth in Neuro 2A cells. We showed that Neuro 2A cells endogenously expressed NPFF2 receptor, and the NPFF2 receptor agonist dNPA inhibited cyclic adenosine monophosphate (cAMP) production stimulated by forskolin in Neuro 2A cells. We also demonstrated that NPFF and dNPA dose-dependently induced neurite outgrowth in Neuro 2A cells, which was completely abolished by the NPFF receptor antagonist RF9. Pretreatment with mitogen-activated protein kinase inhibitors PD98059 and U0126 decreased dNPA-induced neurite outgrowth. In addition, dNPA increased phosphorylation of extracellular signal-regulated kinase (ERK) in Neuro 2A cells, which was completely antagonized by pretreatment with U0126. Our results suggest that activation of NPFF2 receptor stimulates neurite outgrowth in Neuro 2A cells through activation of the ERK signaling pathway. Moreover, NPFF2 receptor may be a potential therapeutic target for neural injury and degeneration in the future.

Abstract
In this investigation, a model of type 2 diabetes mellitus (T2DM) was used on Sprague-Dawley (SD) rats to clarify more details of the mechanism in the therapy of T2DM. D-chiro-inositol (DCI) was administrated to the diabetic rats as two doses [30, 60 mg/(kg·body weight·day)]. The biochemical indices revealed that DCI had a positive effect on hypoglycemic activity and promoted the glycogen synthesis. The rats in DCI high-dosage group had a blood glucose reduction rate of 21.5% after 5 weeks of treatment, and had insulin content in serum about 15.3 ± 2.37 mIU/L which was significantly decreased than diabetes control group. Real-time polymerase chain reaction (RT-PCR) results revealed that DCI gave a positive regulation on glycogen synthase (GS) and protein glucose transporter-4 (Glut4). Western blotting suggested that DCI could up-regulated the expression of the phosphatidylinositol-3-kinase (PI3K) p85, PI3Kp110, GS as well as the phosphorylation of protein kinase B (Akt) both in the liver and the skeletal muscle. The results also revealed that DCI enhanced the Glut4 expression on skeletal muscle. Above all, DCI played a positive role in regulating insulin-mediated glucose uptake through the PI3K/Akt signaling pathway in T2DM rats.

Abstract
OBJECTIVE To assess the efficacy and safety of mammalian target of rapamycin (mTOR) inhibitor rapamycin in treatment of children with cardiac rhabdomyoma, associated with tuberous sclerosis complex (TSC). METHOD The clinical data of children with cardiac rhabdomyomas, who had received a diagnosis of TSC previously, were collected between September 2011 and November 2015 from Pediatric Department of the People's Liberation Army General Hospital.Patients in line with the inclusion criteria received long-term treatment with sirolimus.The starting doses of sirolimus was 1 mg/ (m(2)·d), and the plasma concentration was maintained at 5-10 μg/L.The size and number of cardiac rhabdomyomas were analyzed after treatment with rapamycin, and the efficacy and safety were assessed. The Wilcoxon test was used to analyze data. RESULT All the 51 children met the inclusion and exclusion criteria, including 30 males and 21 females.The median age for rapamycin treatment was 15.0 months (7.0-35.0 months). Tumors disappeared in 26 (51%) children, decreased by more than 50%(including 50%) in 15 (29%) children, decreased by less than 50% in 5 (12%) children, and had no change or progressed in 4 (8%) children.The number of tumors decreased by 77(72%). The median maximum diameter of tumor was 8.7 (5.9-11.3) mm before treatment, 0.0 (0.0-4.0) mm after treatment, and the median decrease of tumor size were 6.7 (3.9-10.0) mm (Z=-8.817, P<0.01). The median disappearance time was 3.26 (2.92-5.37) months.Among different age groups, after treatment by rapamycin, the rate of tumor's disappearance was 50% (12/24) in 0-1 years group.Tumors disappeared in 10 of 16 patients in >1-3 years group and in 4 of 11 patients in >3 years group.The rate of tumor's disappearance was the highest after 3 months of treatment as compared with 6 and 12 months of treatment.Ten children had adverse event that was related to rapamycin.Canker sore was reported in one child and dyslipidemia was reported in 9 children. CONCLUSION Rapamycin is efficacious and well tolerate in treatment of cardiac rhabdomyomas associate with TSC, and lead to a reduction in tumor size and number, in addition, significantly shorten the duration of cardiac rhabdomyoma.

Abstract
BACKGROUND AND PURPOSE Neuropeptide FF (NPFF) behaves as an endogenous opioid-modulating peptide. In the present study, the opioid and NPFF pharmacophore-containing chimeric peptide BN-9 was synthesized and pharmacologically characterized. EXPERIMENTAL APPROACH Agonist activities of BN-9 at opioid and NPFF receptors were characterized in in vitro cAMP assays. Antinociceptive activities of BN-9 were evaluated in the mouse tail-flick and formalin tests. Furthermore, its side effects were investigated in rotarod, antinociceptive tolerance, reward and gastrointestinal transit tests. KEY RESULTS BN-9 acted as a novel multifunctional agonist at μ, δ, κ, NPFF1 and NPFF2 receptors in cAMP assays. In the tail-flick test, BN-9 produced dose-related antinociception and was approximately equipotent to morphine; this antinociception was blocked by μ and κ receptor antagonists, but not by the δ receptor antagonist. In the formalin test, supraspinal administration of BN-9 produced significant analgesia. Notably, repeated administration of BN-9 produced analgesia without loss of potency over 8 days. In contrast, repeated i.c.v. co-administration of BN-9 with the NPFF receptor antagonist RF9 produced significant antinociceptive tolerance. Furthermore, i.c.v. BN-9 induced conditioned place preference. When given by the same routes, BN-9 had a more than eightfold higher ED50 value for gastrointestinal transit inhibition compared with the ED50 values for antinociception. CONCLUSIONS AND IMPLICATIONS BN-9 produced a robust, nontolerance-forming analgesia with limited inhibition of gastrointestinal transit. As BN-9 is able to activate both opioid and NPFF systems, this provides an interesting approach for the development of novel analgesics with minimal side effects.

Abstract
OBJECTIVE To study the clinical characteristics of post-traumatic endophthalmitis following open-globe injury and identify factors affecting its frequency in order to gain further knowledge about possible risk factors for the development of endophthalmitis. METHODS All consecutive records of open globe injury cases (4968 eyes in 4865 inpatients) in 15 tertiary referral hospitals in China over 5 years (January 2001 to December 2005) were retrospectively reviewed. The information was collected from a standardised database of eye injuries from which a detailed analysis of factors influencing the incidence of endophthalmitis was performed. RESULTS 173 eyes (one bilateral rupture of a male) removed within 24 h after trauma were excluded. It was observed that 571 eyes (571 patients) out of a total of 4795 eyes (4693 patients) developed endophthalmitis, and the rate of incidence was 11.91%. Laceration was an independent risk factor for open globe injury. Primary repair within 24 h, intraocular tissue prolapse and self-sealing of wounds seemed to impart protective effects against the development of endophthalmitis. However, gender, age, lens breach and posterior zone of wounds were not significant. Intravitreal antibiotic and corticosteroid therapy was administered to 53 eyes (9.28%), and vitrectomy was performed on 305 eyes (53.42%). At discharge or follow-up, the proportion (16.81%) of enucleation/evisceration of eyes with endophthalmitis was higher than that (8.71%) without endophthalmitis. CONCLUSIONS Laceration was associatied with a significantly higher risk of endophthalmitis for open globe injuries. Early primary repair, intraocular tissue prolapse and self-sealing of wounds were independent protective factors against the development of endophthalmitis.

Abstract
The intact liver exists in a state of replicative quiescence. The factor(s) responsible for maintaining this state and their tissue sources have yet to be identified. Because the colon synthesizes and/or absorbs numerous agents that inhibit hepatocyte proliferation, the principle purpose of this study was to determine whether total colectomy would result in the conversion of quiescent livers to a state of replicative competence. Thus, adult, male Sprague-Dawley rats (250-300 g) were randomized to undergo either total colectomy with ileostomy or sham surgery. Thereafter, rats were sacrificed (N=3-6/group) at times 15 and 30 min and 1, 2, 6, and 24 hr and the livers analyzed by Northern blot analyses for mRNA of the following immediate-early proto-oncogenes (IEP genes): c-fos, c-jun, and c-myc. Rats sacrificed at 24 hr also had hepatic regenerative activity documented by [3H]thymidine incorporation into hepatic DNA. The results of the study revealed that within 15 min, c-fos and c-jun mRNA expression increased in colectomized rats, with peak expression occurring at 30 and 60 min, respectively. c-myc mRNA expression was more delayed, with peak expression occurring at 6 hr post-colectomy. IEP gene expression also increased somewhat in sham-colectomy controls but the increases were not as prompt and, in general, were of lower magnitude than those in the colectomy group. Despite the differences in IEP gene expression between the two groups, [3H]thymidine incorporation at 24 hr was similar (mean+/-SE: colectomy group, 17.2+/-2.6 dpm/microg DNA; sham-colectomy controls, 14.8+/-1.4 dpm/microg DNA). To determine whether the increases in IEP gene expression expedite or augment the hepatic regenerative response to partial hepatectomy (PHx), rats that had undergone colectomy or sham colectomy 1 hr earlier and rats with no previous abdominal surgery then underwent a 70% PHx and were sacrificed at 8, 16, and 24 hr thereafter. At each time interval, [3H]thymidine incorporation was documented and found to be similar in the three groups. In conclusion, the results of this study indicate that total colectomy, and to a lesser extent abdominal surgery, induces the conversion of an intact, quiescent liver to a state of replicative competence. The results also suggest that, in addition to colectomy, the presence of mitogens and/or co-mitogens is required for further progression of hepatocytes through the cell cycle. Finally, a "primed" liver does not respond more promptly or vigorously to a regenerative stimulus than a "resting" liver.

Abstract
Immediate-early protooncogenes (IEP) are thought to play an important role in hepatocyte replication. Whether the extent of their expression correlates with the strength of the proliferative stimulus and subsequent regenerative activity has yet to be documented in vivo. Data are also lacking with respect to the level at which liver disease is associated with biochemical evidence of hepatic dysfunction. Thus, the objectives of this study were to determine whether a correlation exists between IEP gene mRNA expression and varying extents of partial hepatectomy (PHx) and to document the extent of resection required to result in increases in serum bilirubin levels. Eighty-nine adult, male Sprague-Dawley rats underwent either sham surgery or 20%, 35%, 55%, 70% or 90% PHx. Postoperatively, rats were killed (N = 3-6/group) at 15 and 30 mins and 8 and 24 hrs for c-fos, c-jun, and c-myc mRNA expression by northern blot analyses. Rats killed at 24 hrs also had hepatic regenerative activity documented by [3H]thymidine incorporation into hepatic DNA and serum bilirubin determinations. While c-fos mRNA expression at 15 mins and c-myc mRNA expression at 8 hrs after PHx did not correlate with the extent of PHx (r2 = 0.478 and 0.018, respectively), a weak correlation existed between c-jun mRNA expression at 30 mins and the extent of PHx (r2 = 0.662, P < 0.05). In terms of IEP mRNA expression and hepatic regenerative activity, a strong correlation existed between c-fos mRNA expression and [3H]thymidine incorporation (r2 = 0.851, P < 0.01) but not c-jun or c-myc mRNA expression. Compared to sham operated controls, [3H]thymidine incorporation was 2.0x, 3.4x, 3.2x, 7.8x, and 2.2x increased following 20%, 35%, 55%, 70%, and 90% PHx, respectively. Serum bilirubin levels remained unchanged until 70% PHx, when they increased from baseline values of 0.54+/-0.05 mg/dl to 1.02+/-0.15 mg/dl (P < 0.05). A further increase occurred following 90% PHx (1.83+/-0.30 mg/dl, P < 0.01). In conclusion these findings indicate that c-fos mRNA expression 15 mins after PHx correlates with hepatic regenerative activity but not the strength of the regenerative stimulus and that hepatic parenchymal loss of 55-70% must occur prior to the detection of elevated serum bilirubin levels. The results also indicate that relative to a 70% PHx, 90% PHx is associated with decreased rather than increased hepatic regenerative activity.

Abstract
The purpose of this study was to identify the mechanism(s) whereby acute ethanol exposure inhibits hepatic regenerative activity in the rat. Adult, male, Sprague-Dawley rats (200-250 g) were randomized to receive either ethanol (1 g/kg i.p. q 4 h) or an equal volume of saline (controls) for 24 h beginning 1 h prior to a 70% partial hepatectomy (PHx). At 0, 3, 6, 12 and 24 h post-PHx, rats were sacrificed (N = 4-6/group), and the expression of the following genes associated with inhibition of hepatocyte proliferation were documented; p53, p21, transforming growth factor-beta1 (TGF-beta1) and gamma aminobutyric acid transport protein (GABA-TP). Inhibition of hepatic regenerative activity was confirmed by 3H-thymidine incorporation into hepatic DNA at 24 h post-PHx. The results of the study revealed that in ethanol-treated rats, DNA synthesis was inhibited by 37% when compared to saline-treated controls (p < 0.01). Regarding suppressor gene expression, both p21 and TGF-beta1 mRNA expression in ethanol-treated rats were similar to those obtained in saline-treated controls. Although p53 mRNA expression differed in the two groups, in the ethanol-treated group, p53 mRNA expression was decreased rather than increased (relative to controls) at 24 h post-PHx, a finding not in keeping with inhibition of DNA synthesis. GABA-TP mRNA was strongly expressed prior to PHx in both ethanol- and saline-treated rats. Following PHx, GABA-TP mRNA expression decreased in both groups but remained low in the saline-treated group while returning to pre-PHx values in ethanol-treated rats. In summary, the results of this study indicate that the inhibitory effects of ethanol on hepatic regeneration are not associated with significant or the appropriate changes in mRNA expression of the p53, p21 or TGF-beta1 suppressor genes. On the other hand, transcriptional changes in GABA-TP gene expression post-PHx are in keeping with an inhibitory effect of GABA on hepatic regeneration.

Abstract
Expression of hepatic fatty acid binding protein (FABP) mRNA is regulated by growth hormone. In the absence of growth hormone, there is a 60% reduction in FABP mRNA levels (S.A. Berry, J.-B Yoon, U. List, and S. Seelig. J. Am. Coll. Nutr. 12:638-642. 1995). Previous work in our laboratory focused on the role of extracellular binding proteins in the hepatic uptake of long chain fatty acids. In the present study we were interested to determine the role of FABP in the transmembrane flux of long chain fatty acids. Using hepatocyte monolayers from control (n = 9) and hypophysectomized (n = 6) rats, we investigated the uptake of [3H]palmitate in the presence and absence of albumin. In the absence of albumin, total hepatocyte [3H]palmitate clearance rates from control (17.2 +/- 1.5 microL.mg-1 protein.s-1; mean +/- SEM; n = 9) and hypophysectomized (15.5 +/- 2.1 microL.mg-1 protein.s-1; n = 6) animals were similar (p > 0.05). In the presence of 2 microM albumin the total [3H]palmitate clearance rate from control hepatocytes (1.63 +/- 0.11 microL.mg-1 protein.s-1; n = 9) was significantly larger (40%) than from hepatocytes obtained from hypophysectomized (0.97 +/- 0.15 microL.mg-1 protein.s-1; n = 6; p < 0.01) animals. SDS-PAGE electrophoresis revealed that plasma membrane FABP levels from control and hypophysectomized animals were similar. However, there was a 49% decrease in the cytosolic FABP levels of hepatocytes isolated from hypophysectomized as compared with control animals. The decreased cytosolic FABB levels paralleled the decrease in palmitate uptake. We conclude that in the absence of extracellular binding proteins the rate-limiting step in the overall uptake of long chain fatty acids is diffusion to the cell surface. However, in the presence of albumin, the rate of palmitate uptake is determined primarily by cytosolic FABP levels.

Abstract
Plasma motilin concentration were determined by radioimmunoaction from 180 women during pregnancy and early postpartum period as compared with 20 healthy non-pregnant women. The results showed that mean plasma motilin concentration (384.40 +/- 110.30 ng/L) was higher in the first trimester of pregnancy than that of healthy non-pregnant women (366.12 +/- 96.23 ng/L), however, this difference did not reach statistical significance (P > 0.05). The mean plasma motilin concentration (323.90 +/- 125.10 ng/L) was lower in the second trimester of pregnancy than in the first trimester of pregnancy (P < 0.05), while the mean plasma motilin concentration in the third trimester of pregnancy (121.04 +/- 27.00 ng/L) was significantly lower than in second (P < 0.01) and the mean plasma motilin concentration in 3-5 d after delivery (443.05 +/- 140.79 ng/L) reached an even higher value (P < 0.01). Our results suggests that pregnancy appears to have a profound inhibitory effect on plasma motilin and this may in part be responsible for the gastrointestinal hypomotility during pregnancy.
