Objective:To study the changes in long non-coding RNA C2dat1 expression in kidney tissues of rats at different stages of diabetic kidney disease (DKD) and its relationship with renal interstitial fibrosis.Methods:Forty-eight male SD rats were randomly divided into two groups with 24 rats in each group: control group and DKD group. The rats in the control group were fed with ordinary diet, while those in the DKD group were fed with high-fat diet and drank water freely. After eight weeks of feeding, the rats were fasted for 12 h with free access to water. Then, the DKD group was given a one-time intrabitoneal injection of streptozotocin and the control group was given an equal dose of sodium citrate buffer. After 72 h, the random peripheral blood glucose concentration (≥ 16.7 mmol/L for three consecutive days) and urine sugar (positive) were tested to assess the establishment of the diabetes model. Urine, blood and kidney samples were collected at 3, 6, 9 and 12 weeks. The urinary protein excretion rate within 24 h, urinary creatinine and serum total cholesterol were measured by automatic biochemical apparatus. Pathological changes in kidney tissues were observed by HE staining. The expression of calcium/calmodulin-dependent protein kinase Ⅱ delta (CaMK2D), p65, p50, α-SMA and E-cardherin was detected by immunohistochemistry. Quantitative real-time PCR (qPCR) was used to detect the expression of lncRNA C2dat1 and CaMK2D. The relationship of lncRNA C2dat1 with α-SMA, E-cardherin and CaMK2D was analyzed by correlation analysis. In in vitro experiment, renal tubular epithelial cells HK-2 were induced by high glucose. The expression of lncRNA C2dat1 and CaMK2D in HK-2 cells was detected by qPCR after 24, 48 and 72 h of intervention. Results:The rats in the DKD group showed typical symptoms such as polydipsia, polyphagia, significant weight loss and increased blood glucose as compared with the rats in the control group. Results of the biochemical tests revealed that compared with the control group, the DKD group had increased 24 h excretion rate of urinary protein, decreased urinary creatinine and up-regulated total cholesterol. HE staining showed that the rats in the control group had intact glomeruli, normal basement membrane and no mesangial hyperplasia or inflammatory cell infiltration. However, enlarged glomeruli and evenly thickened basement membrane were observed in the DKD group. Immunohistochemistry indicated that the expression of CaMK2D, p50 and α-SMA was higher in the DKD group than in the control group, while the expression of E-cardherin was lower in the DKD group. qPCR results showed that the expression of lncRNA C2dat1 and CaMK2D at mRNA level was higher in the DKD group than in the control group. In in vitro experiment, the expression of lncRNA C2dat1 and CaMK2D at mRNA level was also higher in HK-2 cells induced by high glucose than in the control group. Correlation analysis indicated that lncRNA C2dat1 was positively correlated with α-SMA and CaMK2D, but negatively correlated with E-cardherin. Conclusions:During the progression of DKD, the high expression of lncRNA C2dat1 might promote diabetic renal interstitial fibrosis by regulating the expression of CaMK2D to activate the NF-κB signaling pathway.

Objective:To investigate the clinical characteristics of children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variants, and the impact factors of duration of cycle threshold (Ct) values turning to ≥35 detected by nucleotide test.Methods:Children aged 0 to 14 years with clinical symptoms of Omicron variants infection who admitted to designated hospital in Shanghai City (Renji Hospital, South Branch, Shanghai Jiao Tong University School of Medicine) from April 7 to June 2, 2022 were enrolled. The daily nasopharyngeal swab specimens were used for SARS-CoV-2 nucleic acid detecting by polymerase chain reaction and the results were expressed as Ct values. The T Ct≥ x was defined as from the symptom onset or first positive nucleic acid test results (the earlier data) to Ct≥ x of the open reading frame 1ab ( ORF1 ab) gene, which was the time duration from the initial to a specific Ct value.Clinical data were collected, including age, sex, vaccination and comorbidities.Cox model was performed to analyzed the impact factors of T Ct≥35. Results:A total of 871 pediatric cases with a median age of two years (ranging from one month to 14 years old) were included. Among them, 474 cases (54.4%) were male, and 89 cases (10.2%) had underlying diseases including congenital heart disease, solid tumors and epilepsy. There were 572(65.7%) mild cases, 298(34.2%) common cases, one (0.1%) severe case and no critical cases or deaths. The T Ct≥35 was 12(10, 14) days. Cox model indicated that compared to children aged one to 12 months, children aged 37 to 84 months and 85 to 168 months had shorter T Ct≥35 (hazard ratio ( HR)=1.55 and 1.84, respectively, both P<0.001). After adjusted with age, comparing to unvaccinated patients, patients with one or two shots vaccine had shorter T Ct≥35 (adjected hazard ratio (a HR)=1.49, P=0.011), and common patients had longer T Ct≥35 than mild patients (a HR=0.78, P=0.002), and patients with comorbidities had longer T Ct≥35than patients without comorbidities (a HR=0.38, P<0.001).The duration of T Ct≥28, T Ct≥30, T Ct≥33 and T Ct≥35 in children without underlying diseases were 7(6, 9) d, 9(7, 10) d, 10(8, 11) d and 12(10, 14) d, respectively. Conclusions:Age, vaccination, disease severity and underlying diseases could affect the duration of SARS-CoV-2 nucleotide turning to negative (Ct value≥35) in children infected with Omicron variants.

OBJECTIVE To evaluat e the cost-effectiveness of Keluoxin capsule combi ned with chemical medicine in the treatment of diabetic kidney disease （DKD）from the perspective of the whole society. METHODS Six-state Markov model with 1 year cycle and 40 years time horizon was constructed by means of secondary literature review ，medical record analysis of sample hospital and clinical expert consultation. The cost-effectiveness of Keluoxin capsule combined with chemical medicine versus chemical medicine alone for DKD was evaluated by taking the quality-adjusted life year （QALY）as the output index ，setting the discount rate as 5％，and taking one time domestic gross domestic product （GDP）per capita in 2020 of China as the judgement threshold of incremental cost-effectiveness ratio （ICER）. RESULTS Within 40 years，Keluoxin capsule combined with chemical medicine group spent 8 644.09 yuan per capita more than chemical medicine alone group ，and gained more 0.143 QALYs；ICER was 60 460.25 yuan/QALY，which was less than one times GDP per capita of China in 2020（72 447 yuan）. The results of sensitivity analysis showed that the annual days of using Keluoxin capsule ，the health utility value of DKD at early stage had a great influence on the results of cost-effectiveness analysis. The results of probabilistic sensitivity analysis suggested that the basic analysis results of this study were robust. CONCLUSIONS At the current price level ，Keluoxin capsule combined with chemical medicine is more cost-effective to treat DKD than chemical medicine alone. The dosage of Keluoxin capsule and health utility value should be paid attention in specific decision- bjmu.edu.cn making scenarios.

Objective:To investigate the clinical epidemiological data of children with prolonged mechanical ventilation (PMV) in pediatric intensive care unit(PICU), and analyze the primary disease of children with PMV as well as the disease characteristics and prognosis of children with PMV under different kinds of primary disease.Methods:The clinical data of hospitalized children with PMV in PICU at Children′s Hospital of Fudan University from January 2019 to December 2020 were retrospectively collected.Results:A total of 46 children with PMV were collected.There were 18 males (39.1%) and 28 females (60.9%). The median age was 37 (8, 86) months and the median body weight was 15 (7, 20) kg.The average pediatric critical illness score at admission was 84.2±7.7, PaO 2/FiO 2 was (245.5±99.8)mmHg.The primary diseases leading to PMV were as follows: there were 14 cases of severe pneumonia, eight cases of severe encephalitis, five cases of bronchopulmonary dysplasia, three cases of upper airway obstruction/craniofacial deformity, three cases of myasthenia, three cases of brain stem tumor, three cases of mitochondrial encephalomyopathy, two cases of spinal muscular atrophy, two cases of Prader-Willi syndrome, one case of dermatomyositis, one case of severe brain injury, and one case of central hypoventilation.The causes of unable to withdraw ventilator were respiratory dysfunction in 24 cases, brain dysfunction in 16 cases, and diaphragm dysfunction in six cases.Compared with neuromuscular diseases, children with PMV caused by respiratory diseases had lower month age, higher preterm birth rate, lower PaO 2/FiO 2 ratio, higher parameters for ventilator treatment, and the differences were statistically significant ( P<0.05). Children with PMV caused by neuromuscular diseases had lower Glasgow coma score and higher coma rate, and the differences were statistically significant ( P<0.05). A total of nine (19.6%) cases underwent tracheotomy.A total of 23 (50.0%) cases were successfully extubated from ventilator, six (13.0%) cases were dependent on invasive ventilator, and six (13.0%) cases were breathing with tracheotomy tube.The median mechanical ventilation time was 33 (28, 40) days, the median PICU hospital stay was 42 (34, 56) days, and the median hospital stay was 51 (41, 65) days.A total of 27 (58.7%) cases were improved and discharged, four (8.7%) cases were transferred to rehabilitation hospital, four (8.7%) cases were transferred to local hospital, and 11 (23.9%) cases died in hospital or at home after giving up. Conclusion:The main causes of PMV in PICU children are respiratory dysfunction, brain dysfunction and diaphragm dysfunction.50.0% of the children with PMV could be discharged from the ventilator, and 23.9% died or died after giving up.

ObjectiveTo screen out the mRNAs involved in the resistance of hepatoma cells to anlotinib using ceRNA microarray. MethodsHigh-dose shock combined with low-dose induction was used to culture hepatoma cells resistant to anlotinib, and CCK8 assay was used to verify the difference in the proliferation of drug-resistant hepatoma cells treated by anlotinib. The ceRNA microarray was used to screen out the differentially expressed genes between drug-resistant hepatoma cells and normal hepatoma cells, and real-time PCR was used to verify the differentially expressed genes detected by some microarrays. the independent samples t-test was used for comparison of continuous data between two groups, and the Kaplan-Meier method was used to analyze the overall survival of hepatoma cells samples, and the log-rank test was used to compare survival rates. Fisher’s exact test was used for chip screening. ResultsThere was a significant difference in gene expression between drug-resistant hepatoma cells and normal hepatoma cells, and 10 genes with the greatest difference were screened out for analysis by reducing the range. There were 4 genes associated with drug resistance and tumor growth, i.e., BIRC2, BIRC7, ABCC2, and MAPK8. There were significant reductions in the expression levels of BIRC2, ABCC2, and MAPK8 (P=0001 4, 0001 2, and 0.011 8), and there was a significant increase in the expression of BIRC7 (P＜0.001). The results of real-time PCR were consistent with those of microarray (t=10.74,32.65,18.34, and 2.80; P=0.000 4, 0.000 1, 0.000 1, and 0.044 8). The high expression of BIRC7 and the low expression of MAPK8 were associated with the significant reduction in survival time (P=0.022 0 and 0.005 6). ConclusionBIRC2, BIRC7, ABCC2, and MAPK8 are differentially expressed between anlotinib-resistant hepatoma cells and normal hepatoma cells and may be involved in the resistance of hepatoma cells to anlotinib.

Objective:To explore the significance of serum thyroglobulin (Tg) in the decision-making of response to 131I therapy and subsequent treatment for distant metastatic differentiated thyroid cancer (DM-DTC). Methods:Between January 2018 and December 2019, a total of 62 papillary thyroid cancer (PTC) patients (20 males and 42 females, age: (38.1±15.9) years) with pulmonary metastasis from Peking Union Medical College Hospital were retrospectively analyzed. Patients were divided into two groups (non-radioactive iodine (RAI)-avid group and RAI-avid group) according to the post-treatment whole body scan (Rx-WBS). The serum Tg response to 131I therapy including Tg change and Tg change speed was compared between two groups, and the relationship between serum Tg change speed and structural progression was explored by binary logistic regression analysis. The Tg response to different treatment schemes ( 131I treatment or follow-up) was compared in non-RAI-avid group. χ2 test and Mann-Whitney U test were used to compare data between different groups. Receiver operating characteristic (ROC) curve analysis was used to find the best threshold of Tg change speed to predict the structural progress. Results:After 131I treatment, increased Tg level was found in 60.0% (15/25) patients in non-RAI-avid group ( n=25), while only 21.6%(8/37) patients in RAI-avid group ( n=37; χ2=9.417, P=0.002). Non-RAI-avid group showed an overall increased Tg trend, with a speed of 0.05(-0.16, 0.15) μg·L -1·month -1, while RAI-avid group showed a general decreased Tg trend, with a speed of -0.18(-1.95, 0.01) μg·L -1·month -1 ( U=265.000, P=0.005). A significant correlation between Tg change speed and structural response (odds ratio ( OR)=53.005, P<0.001) was found. When Tg change speed was more than 0.135 μg·L -1·month -1, structural progression could be well predicted with the sensitivity of 87.5% and specificity of 97.1%. In comparison to non-RAI-avid patients with merely follow-up, further 131I treatment for such patients did not yield significant benefit in terms of Tg change and Tg change speed ( χ2=0.071, U=394.000; both P>0.05). Conclusions:The serum Tg monitoring can be more sensitive in evaluating the therapeutic response to 131I for DM-DTC patients in whom response evaluation criteria in solid tumors (RECIST) might not be sensitive enough to reflect the minor change. For patients with non-RAI-avidity, Tg evaluation will offer more sensitive evidence to tailor the necessity of further 131I treatment.

Objective To establish an animal model of neurogenic pulmonary edema (NPE),and to study the role of catecholamine and beta receptors in the occurrence of NPE. Methods The NPE model was established by injecting fibrinogen and thrombin into the cerebellum medullary pool of the rabbits. Twenty-four rabbits were divided into the control group,the saline group and the experimental group by random num-ber table. In the control group,only cerebellar medullary cistern puncture was carried out,and no drug was in-jected. Cerebrospinal fluid was drew out and the same amount of saline was injected into the cerebellum me-dullary pool in the saline group. Fibrinogen and thrombin were injected into the cerebellum medullary pool in the experimental group. The animals were intubated by tracheotomy,the femoral artery and the internal jugu-lar vein were dissected and connected with the PiCCO instrument to detect the blood pressure,heart rate,and respiratory rate before puncture and at 1 min,10 min,30 min after puncture. Serum samples were collected for the determination of epinephrine,norepinephrine,acetylcholine,endothelin-1,cardiac troponin I,brain natri-uretic peptide and neuropeptide Y levels before puncture and at 1 min,10 min after puncture. The rabbits weresacrificed at 3 hours after successful modeling,the pathological examination of lung was performed. Myocar-dial samples were taken to detect adrenergic beta receptors mRNA. Results (1)The heart rate,respiratory rate and mean arterial pressure at 1 min and 10 min after puncture in experimental group were significantly higher than those in control group and saline group. (2) The pathological examination of the rabbits′ lungs in experimental group found that the lung tissue was swollen and dark red in appearance with large areas of con-gestion. Under the microscope,the lung tissue was edema,bleeding,and inflammatory cells were infiltrated in the alveolar cavity,which was consistent with characteristics of NPE. (3)There was no difference in epineph-rine and norepinephrine concentration in all groups before the cerebellar medullary pool puncture. The concen-tration of epinephrine and norepinephrine at 1 min after puncture time were (200. 0 ± 251. 7)μg/ L,(448. 9 ± 356. 7)μg/ L in the experimental group,whcih were significantly higher than those of control group[(15. 4 ± 3. 4)μg/ L,(15. 9 ± 9. 7)μg/ L] and saline group[(17. 1 ± 3. 8) μg/ L,(29. 6 ± 18. 4) μg/ L] (P < 0. 05). The concentration of epinephrine and norepinephrine at 10 min after puncture were (397. 0 ± 797. 7)μg/ L, (221. 4 ± 173. 7)μg/ L in the experimental group,whcih were significantly higher than those of control group [(23. 3 ± 6. 4) μg/ L,(18. 8 ± 3. 9) μg/ L] and saline group[(16. 7 ± 9. 1) μg/ L,(20. 3 ± 6. 5) μg/ L] (P < 0. 05). (4)There was no significant difference in the levels of serum neuropeptide Y,acetylcholine and endothelin-1 among the three groups. (5)The mRNA of adrenergic beta-1 receptor in the experimental group was 0. 37 ± 0. 12,which was significantly lower than those in the control group (0. 54 ± 0. 13) and saline group (0. 56 ± 0. 14) (P < 0. 05). There was no significant difference in adrenergic beta-3 receptor mRNA among the three groups. Conclusion The NPE animal model was constructed by injecting fibrinogen and thrombin into the cerebellum medullary pool of the rabbits. Catecholamine and beta-1 receptor play a role in the occurrence of NPE rabbit model. There is no significant correlation between neuropeptide Y,acetylcholine,en-dothelin-1 and the occurrence of NPE in rabbits.

Objective To investigate the treatment,outcomes and disease burden of severe hand-foot-and mouth diseases(HFMD),and to evaluate the compliance to the 2011 guideline for treatment in regions with a high in-cidence of HFMD.Methods A collaborative study group was established including Children's Hospital of Fudan Uni-versity,Jiangxi Provincial Children's Hospital,Anhui Provincial Children's Hospital,Linyi People's Hospital and the Second People's Hospital of Fuyang City.Clinical manifestation,treatment,prognosis and other data of severe HFMD pa-tients were prospectively collected by filling out a survey form in real time from April 2014 to October 2016. Results Two hundred and twenty-six severe HFMD cases were collected during the research time,including 114 ca-ses in stage 2,75 cases in stage 3,and 37 cases in stage 4.Two hundred and twenty-one cases(97.8%)were given mannitol,with a mortality of 6.2%;91 cases(40.3%)were given mannitol and glycerol fructose,with a mortality of 3.3%;the combined use of mannitol and glycerol fructose might have a better result than the single use of mannitol. One hundred and ninety-eight cases(87.6%)were given intravenous immunoglobulin(IVIG).One hundred and ninety cases(84.1%)were given antiviral drugs.One hundred and forty-five cases(64.2%)were given hormone therapy,and the use of hormone could reduce temperature,but did not reduce the mortality.One hundred and fifty cases (66.4%)needed vasoactive agent,including milrinone,dobutamine,phentolamine and sodium nitroprusside. The vasoactive agent use in stage 3 and 4 were 88.0%(66/75 cases)and 91.9%(34/37 cases),respectively.Sixty-nine cases(30.5%)received continuous positive airway pressure(CPAP),91 cases(40.3%)with mechanical ventila-tion,peak inspiratory pressure(PIP)≥20 cmH2O(1 cmH2O=0.098 kPa)accounted for 61.6%(53/86 cases),po-sitive end-expiratory pressure(PEEP)≥10 cmH2O accounted for 36.3%(33/91 cases).The mean mechanical ven-tilation time was(125.9 ± 101.8)h.Eleven cases(4.86%)died or died after giving up treatment,in which the mortality in stage 3 was 6.7%(5/75 cases),and the mortality in stage 4 was 16.2%(6/37 cases).The death causes were respiratory failure,pulmonary hemorrhage,and circulatory failure. The average time from onset to death was (5.91 ± 5.26)(1-15)d.Length of stay in hospital was(9.18 ± 5.16)(1-37)d in which length of stay in hospi-tal in stage 3 and 4 were(11.3 ± 6.35)d,(11.4 ± 6.62)d,respectively,which were significantly longer than that in stage 2[(7.50 ± 3.04)d],and the difference was statistically significant(P <0.05). The cost was(19 136 ± 12 556)CNY,of which the cost in stage 3 and 4 was(23 121 ± 13 846)CNY,(29 849 ± 16 015)CNY,respectively, which were significantly higher than that in stage 2[(12 961 ± 4 272)CNY],and the difference was statistically sig-nificant(P<0.05). Multivariate analysis found that respiratory rhythm abnormality,capillary refill time more than 3 seconds were risk factors for the deaths in the severe HFMD.Conclusion The 2011 edition of guidelines for treat-ment of children with severe HFMD was well executed.Hormone,IVIG,antiviral drugs did not significantly reduce the mortality of severe HFMD in children.
