Abstract
BACKGROUND The number of pediatric cases of infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant has increased. Here, we describe the clinical characteristics of children in a tertiary children's medical center in Shanghai. METHODS A total of 676 pediatric coronavirus disease 2019 (COVID-19) cases caused by the Omicron variant who were admitted to the Shanghai Children's Medical Center from March 28 to April 30, 2022 were enrolled in this single-center, prospective, observational real-world study. Patient demographics and clinical characteristics, especially COVID-19 vaccine status, were assessed. RESULTS Children of all ages appeared susceptible to the SARS-CoV-2 Omicron variant, with no significant difference between sexes. A high SARS-CoV-2 viral load upon admission was associated with leukocytopenia, neutropenia, and thrombocytopenia (P = 0.003, P = 0.021, and P = 0.017, respectively) but not with physical symptoms or radiographic chest abnormalities. Univariable linear regression models indicated that comorbidities (P = 0.001) were associated with a longer time until viral clearance, and increasing age (P < 0.001) and two doses of COVID-19 vaccine (P = 0.001) were associated with a shorter time to viral clearance. Multivariable analysis revealed an independent effect of comorbidities (P < 0.001) and age (P = 0.003). The interaction effect between age and comorbidity showed that the negative association between age and time to virus clearance remained significant only in patients without underlying diseases (P < 0.001). CONCLUSION This study describes the clinical characteristics of children infected with the Omicron variant of SARS-CoV-2 and calls for additional studies to evaluate the effectiveness and safety of vaccination against COVID-19 in children.

Abstract
Objectives: To analyze the relationship between etiology and morphological classification of benign central airway stenosis and its prognosis. Methods: We performed a retrospective study of the medical records of 453 patients initially diagnosed with benign airway stenosis at Department of Respiratory Diseases in Beijing Tiantan Hospital affiliated to Capital Medical University from January 2003 to October 2019. Of 453 patients, 260 were male. The age of the study population was 12-86(44.0±24.5) years. Results: Among the 453 patients diagnosed with benign central airway stenosis, 161 case (35.5%, including 113 post-tracheostomy tracheal stenosis and 48 post-intubation tracheal stenosis) were iatrogenic; 88 cases were from benign tumors (19.4%), 77 cases from tracheal or bronchial tuberculosis (17.0%), 71 case from tracheal foreign bodies (15.7%). Disease causes varied among different gender or age groups. The main type of stenosis was structural stenosis, of which 241 cases (53.2%) were intra-luminal and 183 cases (40.4%) were scar contracture type. The site of stenosis showed a certain relationship with the causes of stenosis. The stenosis degree was mainly from grade 2 to grade 4 (76.4%), and the length was mainly within 3 cm (84.8%). Single factor analysis on the relationship between disease cause, morphological classification and prognosis of benign central airway stenosis showed statistically better prognosis in groups that were caused by benign tumor, intraductal stenosis or stenosis that were 3-4 in degree and 1-2 degree in length. Conclusion: The common causes of central airway stenosis included iatrogenic stenosis, benign tumor, tracheal or bronchial tuberculosis and tracheal foreign bodies. Benign airway stenosis with different disease causes and morphological classification had different prognosis after bronchoscopic interventional treatment. Clinicians should know the disease causes, morphological characterization and risk factors for benign airway stenosis for earlier diagnosis, treatment or prevention.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Taraxacum mongolicum Hand.-Mazz. has been used in lung cancer treatment in Chinese medicine. However, its specific mechanism of action has not yet been reported, and developing pharmaceutical anti-cancer resources is important. Here, we aimed to elucidate the anti-tumor effects of dandelion in vitro and in vivo and assess its effects on immune function in lung cancer patients. AIM OF THE STUDY In the present study, we mainly observed the therapeutic effects of total flavonoids from Taraxacum mongolicum Hand.-Mazz. (TFTM) on non-small cell lung cancer and its influence on the body's immune function. MATERIALS AND METHODS In vitro experiments on A549 and H1299 cells were performed using the CCK8 method; the proliferation and migration of cells were observed to investigate the wound healing effects of TFTM, and flow cytometry was used to detect the apoptotic rate of TFTM on lung cancer cells. In vivo experiments were preformed to establish a non-small cell lung cancer mouse model using subcutaneously transplanted Lewis cells, and the body weight and tumor growth of the mice were recorded. Hematoxylin and eosin staining was performed for tumor tissue to assess pathological changes. The thymus, spleen, and lungs were isolated for to calculate organ index. The CD4+, CD8+, and CD4+/CD8+ levels were detected in mouse spleen using flow cytometry, and IL-2, IL-3, IFN-γ, and TNF-α levels were determined in serum using enzyme-linked immunosorbent assay. Expressions of IL-2, IL-3, IFN-γ, and TNF-α were detected using quantitative real-time PCR in tumor tissues, and Ki67 expression was observed by immunofluorescence. RESULTS At 24 h, TFTM (100 and 200 μg/mL) had the best inhibitory effect on the proliferation of A549 and H1299 cells. The cell migration rate significantly reduced (P < 0.01), and the tumor inhibition rate increased (P < 0.01) and promoted apoptosis (P < 0.01). The mouse thymus index significantly increased (P < 0.05) and mouse spleen index reduced (P < 0.05). The CD4+, CD8+, and CD4+/CD8+ levels in Lewis lung cancer mouse model increased, as did the levels of IL-2, IL-3, IFN-γ, and TNF-α in the serum and tumor of mice; Ki67 expression in tumor tissues significantly reduced (P < 0.01). CONCLUSION TFTM has an inhibitory effect on lung cancer. The mechanism may be that it improves the host's protective immune response by having a milder tumor growth inhibitory effect than cyclophosphamide.

Abstract
Mechanical force-induced external root resorption is a major clinical side effect of orthodontic treatment. Recent work has revealed that M1 macrophages play a vital role in promoting orthodontic root resorption (ORR), but the mechanism of how mechanical force stimulation increases the M1/M2 macrophage ratio in periodontal tissue is poorly understood. In the current study, we showed that C-X-C motif chemokine 12 (CXCL12)+ periodontal ligament cells (PDLCs) and C-X-C chemokine receptor type 4 (CXCR4)+ monocytes in the periodontal ligament (PDL) were significantly increased after force application with ongoing root resorption, and these effects were partially rescued after force removal in mice. The expression of CXCL12 in PDLCs was increased by force stimulation in a time- and intensity-dependent manner in vitro. Blockage of the CXCL12/CXCR4 axis using CXCR4 antagonist AMD3100 was sufficient to alleviate ORR and reverse the force-enhanced M1/M2 macrophage ratio. Further mechanism exploration showed that Ly6Chi inflammatory monocytes homed in a CXCL12/CXCR4 axis-dependent manner. The number and proportion of CD11b+ Ly6Chi inflammatory monocytes in cervical lymph nodes were significantly increased by force loading, accompanied by decreased CD11b+ Ly6Chi monocytes in the blood. These changes were blunted by intraperitoneal injection of AMD3100. In addition, blockage of the CXCL12/CXCR4 axis effectively reversed M2 suppression and promoted M1 polarization. Collectively, results indicate that force-induced CXCL12/CXCR4 axis mediates ORR by increasing the M1/M2 ratio in periodontal tissues through attracting Ly6Chi inflammatory monocytes and modulating macrophage polarization. The results also imply that AMD3100 is potentially inhibitory to root resorption.

Abstract
Objective: To analyze the clinical and prognosis of children with kidney retransplantation. Methods: Clinical data of 11 children who underwent kidney retransplantation from January 2011 to December 2020 in Department of Nephrology, Children's Hospital of Fudan University were retrospectilely analyzed. The clinical data including demographic parameters, primary diagnosis, characteristics in the follow-up of renal allograft were analyzed. Results: Totally 11 cases received secondary renal transplantation (male 6, female 5). They were initially diagnosed with chronic kidney disease at the age of 11.9 (7.4, 13.3) years. The median duration of dialysis was 22.1 (3.5, 36.5) months. In the first transplantation, recipient age was 13.9 (11.1, 15.2) years. Ten cases received donation from cardiac death donor (DCD) (9 cases received donors aged less than one year, 5 of them received whole kidney transplantation and one case received donor aged one to three years) and 1 case with living-related donor. Ten graft failures occurred within 1 month after renal transplantation and the other one occurred at the fifth month after transplantation. The causes included vascular factors (9 cases), rejection (1 case) and primary non-function (1 case). In the second transplantation, recipient age was 14.7 (11.7, 16.2) years. All the 11 children received dialysis (7 with PD and 4 with HD) and successfully completed the second transplantation. The median time between the two transplants was 210 (16, 1 041) days. Donors were all DCD donors from 3 years of age or older. The mean follow-up duration was (42±15) months. The estimated glomerular filtration rate was (85±34)ml/(min·1.73 m2) when the last investigation after kidney retransplantation with the kidney and patient all survived. Conclusions: Kidney retransplantation may have better prognosis in children. Dialysis transition during waiting period and DCD donor from 3 years of age or older can effectively ensure the success of kidney retransplantation.

Abstract
BACKGROUND Primary vesicoureteral reflux (VUR) is a common congenital anomaly of the kidney and urinary tract (CAKUT) in childhood. The present study identified the possible genetic contributions to primary VUR in children. METHODS Patients with primary VUR were enrolled and analysed based on a national multi-center registration network (Chinese Children Genetic Kidney Disease Database, CCGKDD) that covered 23 different provinces/regions in China from 2014 to 2019. Genetic causes were sought using whole-exome sequencing (WES) or targeted-exome sequencing. RESULTS A total of 379 unrelated patients (male: female 219:160) with primary VUR were recruited. Sixty-four (16.9%) children had extrarenal manifestations, and 165 (43.5%) patients showed the coexistence of other CAKUT phenotypes. Eighty-eight patient (23.2%) exhibited impaired renal function at their last visit, and 18 of them (20.5%) developed ESRD at the median age of 7.0 (IQR 0.9-11.4) years. A monogenic cause was identified in 28 patients (7.39%). These genes included PAX2 (n = 4), TNXB (n = 3), GATA3 (n = 3), SLIT2 (n = 3), ROBO2 (n = 2), TBX18 (n = 2), and the other 11 genes (one gene for each patient). There was a significant difference in the rate of gene mutations between patients with or without extrarenal complications (14.1% vs. 6%, P = 0.035). The frequency of genetic abnormality was not statistically significant based on the coexistence of another CAKUT (9.6% vs. 5.6%, P = 0.139, Chi-square test) and the grade of reflux (9.4% vs. 6.7%, P = 0.429). Kaplan-Meier survival curve showed that the presence of genetic mutations did affect renal survival (Log-rank test, P = 0.01). PAX2 mutation carriers (HR 5.1, 95% CI 1.3-20.0; P = 0.02) and TNXB mutation carriers (HR 20.3, 95% CI 2.4-168.7; P = 0.01) were associated with increased risk of progression to ESRD. CONCLUSIONS PAX2, TNXB, GATA3 and SLIT2 were the main underlying monogenic causes and accounted for up to 46.4% of monogenic VUR. Extrarenal complications and renal function were significantly related to the findings of genetic factors in children with primary VUR. Like other types of CAKUT, several genes may be responsible for isolated VUR.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The traditional use of Prunella vulgaris is for the treatment of liver cancer in a few areas of China. At present, it is used primarily for the treatment of thyroid cancer, throat cancer, and lymphosarcoma among others. However, there are few current scientific reports regarding its use for the treatment of liver cancer. In this paper, the effective treatment for liver cancer is studied to provide an experimental basis for the application of Prunella vulgaris, which is related to preparations in the treatment of liver cancer. AIM OF THE STUDY To study the anti-hepatocarcinoma effect of Prunella vulgaris total flavonoids and explores the possible molecular mechanism. METHODS The effects of Prunella vulgaris total flavonoids on the proliferation of SMMC-7721 cells were respected by RTCA analysis system. The tumor volume and weight were found in H22 tumor bearing mice. ELISA was used to observe the apoptosis and autophagy protein expressions in tumor tissue homogenate, along with the immune serum factor. Tumor tissue apoptosis was respected by the TUNEL method. And Bax, Bcl2, PI3K, Akt, mTOR, Beclin-1 and LC3-I/LC3-II expression were observed through Western blot. We also observed the expression of Beclin-1 and LC3-I/LC3-II through immunohistochemistry. RESULTS The total flavonoids of Prunella vulgaris inhibited the activity of SMMC-7721 cells, and reduced the tumor volume and weight in H22 tumor bearing mice. HE staining showed that the Prunella vulgaris total flavonoids inhibited liver metastasis of H22 tumor. The Prunella vulgaris total flavonoids significantly made the expressions of IL-6, TNF-α and IFN-γ immune factors increasing in the serum of tumor bearing mice, and the contents of caspase-3 and caspase-9 increase as well in tumor tissue homogenate. TUNEL showed that the mean density in the intervention group was significantly higher than that in the control group. P62 content in tumor tissue homogenate increased and ATG5 decreased after intervention. Immunohistochemistry showed Beclin-1 expression decreased and LC3-I/LC3-II increased in the tumor tissue. Western blot showed Bcl2, Beclin-1 expression decreased and Bax, PI3K, Akt, mTOR, LC3-I/LC3-II increased in the tumor tissue. CONCLUSION Prunella vulgaris total flavonoids have an obvious anti-hepatocarcinoma effect, and the mechanism may be linked to the inhibition of autophagy and promotion of apoptosis in liver cancer cells. The inhibition of autophagy may be related to activation of the PI3K/Akt/mTOR pathway.

Abstract
Ceramic implants have superior performance due to the excellent wear resistance and biocompatibility. However, the poor machinability limits their applications. Plasma sprayed ceramic coating on the additively manufactured metal substrate not only provides a 3-dimensional conformal implant coating and but also forms a highly wear-resistant surface layer. In this paper, three types of ceramic coatings of Al2O3, ZrO2, and Al2O3-ZrO2 composite have been fabricated by atmosphere plasma spray on the CoCrMo alloy substrate prepared by selective laser melting (SLM). It has been found that the Al2O3-ZrO2 composite coating has better corrosion and wear resistance compared with the ceramic coating (Al2O3, ZrO2) and the CoCrMo substrate. The adhesion strength between the Al2O3-ZrO2 composite coating and the substrate reaches 238 MPa. In addition, the wear and corrosion resistance increase with wear progression for all the fabricated ceramic coatings. The highly dense microstructure, fewer microcracks, and the amorphous phases are deterministic factors responsible for the superior tribological and corrosion performance of the Al2O3-ZrO2 composite coating. The fabrication route has been proved very promising to manufacture high-performance implants with ceramic coating.

Abstract
The objective of this study was to determine the ileal digestible energy (IDE), ME, and MEn of rice, broken rice, and rice bran. The birds were fed a standard starter diet from day 0 to 14 and experimental diets from day 15 to 21 after hatching. A total of 336 birds were grouped by BW and assigned to 7 diets, each diet comprised 8 replicates with 6 birds per replicate. The diets comprised a reference diet (RD) and 6 test diets (TD). The TD contained 2 levels of rice, broken rice or rice bran that partly replaced the energy sources in the RD at 120 or 240 g/kg (rice and broken rice) or 150 or 300 g/kg (rice bran). Addition of rice or broken rice to RD linearly increased (P < 0.01) ileal digestibility of DM, energy, as well as total tract metabolizability of DM, energy, and N-corrected energy in the TD. The inclusion of rice bran in the TD linearly decreased (P < 0.01) energy digestibility and utilization in the test diet. Regressions of rice-associated, broken rice-associated, or rice bran-associated IDE, ME, or MEn intake in kcal against rice, broken rice, or rice bran intake were as follows: IDE = Y = 2 (6) + 3,185 (73) × Rice + 3,199 (72) × Broken Rice + 2,562 (61) × Rice Bran, r2 = 0.98; ME = Y = 8 (6) + 3,103 (72) × Rice + 3,190 (71) × Broken Rice + 2,709 (60) × Rice Bran, r2 = 0.98; MEn = Y = 4 (5) + 3,014 (68) × Rice + 3,092 (101) × Broken Rice + 2,624 (57) × Rice Bran, r2 = 0.98; Based on the regression equations, the IDE, ME, MEn values (kcal/kg of DM) of rice were 3,185, 3,103 and 3,014, respectively, while for broken rice, the values were 3,199, 3,190, and 3,092 and for rice bran, the values were 2,562, 2,709, and 2,624, respectively.

Abstract
BACKGROUND AND OBJECTIVES During the coronavirus disease 2019 outbreak, the treatment of families with children on long-term KRT is challenging. This study was conducted to identify the current difficulties, worries regarding the next 2 months, and mental distress experienced by families with children on long-term KRT during the coronavirus disease 2019 outbreak and to deliver possible management approaches to ensure uninterrupted treatment for children on long-term KRT. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A multicenter online survey was conducted between February 10 and 15, 2020, among the families with children on long-term KRT from five major pediatric dialysis centers in mainland China. The primary caregivers of children currently on long-term KRT were eligible and included. Demographic information, severe acute respiratory syndrome coronavirus 2 infection status, current difficulties, and worries regarding the next 2 months were surveyed using a self-developed questionnaire. The Patient Health Questionnaire-9 and the General Anxiety Disorder Scale-7 were used to screen for depressive symptoms and anxiety, respectively. RESULTS Among the children in the 220 families included in data analysis, 113 (51%) children were on dialysis, and the other 107 (49%) had kidney transplants. No families reported confirmed or suspected cases of coronavirus disease 2019. Overall, 135 (61%) and 173 (79%) caregivers reported having difficulties now and having worries regarding the next 2 months, respectively. Dialysis supply shortage (dialysis group) and hard to have blood tests (kidney transplantation group) were most commonly reported. A total of 29 (13%) caregivers had depressive symptoms, and 24 (11%) had anxiety. After the survey, we offered online and offline interventions to address their problems. At the time of the submission of this paper, no treatment interruption had been reported. CONCLUSIONS The coronavirus disease 2019 outbreak has had physical, mental, logistical, and financial effects on families with children on long-term KRT.

Abstract
BACKGROUND This study analysed children with end-stage renal disease treated with automated peritoneal dialysis (APD) in our centre to explore the risk factors associated with residual renal function (RRF) loss. METHODS Children treated with APD as the initial renal replacement therapy regimen from January 2008 to December 2016 were included. All the children had a daily urine volume of ≥100 ml/m2 when APD was initiated and a dialysis follow-up time of ≥12 months. A daily urine volume of <100 ml/m2 after 12 months of APD treatment was defined as loss of RRF. Possible risk factors that may be associated with RRF loss were analysed. RESULTS A total of 66 children were included in the study. After 12 months of APD treatment, the daily urine volume decreased by 377.45 ± 348.80 ml/m2, the residual glomerular filtration rate decreased by 6.39 ± 3.69 ml/min/1.73 m2 and 29 of the patients (43.9%) developed RRF loss. The higher risk of RRF loss after 1 year of APD treatment was most pronounced in patients with daily urine volume of ≤400 ml/m2 before treatment, higher glucose exposure and higher ultrafiltration volume, while the lower risk of RRF loss was in patients with administration of diuretics. Each increase of 1 g/m2/day glucose exposure was associated with a 5% increase in RRF loss (odds ratio (OR) 1.05, p = 0.023) and each increase of 1 ml/m2/day ultrafiltration volume was associated with a 1% increase in RRF loss (OR 1.01, p = 0.013). CONCLUSION In children undergoing APD, the risk for loss of RRF is associated with low urine volume at the start of APD, high glucose loading and high peritoneal ultrafiltration volume, while preservation of RRF is associated with the usage of diuretics.

Abstract
Due to the increasing incidence of central nervous system diseases,especially the increasing incidence and mortality of stroke,brain-targeted drug delivery has attached more and more attention. Nasal administration,as one of the ways of brain-targeted administration,can effectively make the drug delivered to the brain in a targeted way after by passing the blood-brain barrier,providing a new idea for the treatment of central nervous system diseases. Therefore,it is a promising administration way. In recent years,the treatment of encephalopathy by nasal administration of traditional Chinese medicine has become a hot topic in the research of traditional Chinese medicine. Ischemic stroke is one of the most important diseases endangering human health. Nasal administration has a history of thousands of years in treatment of stroke. Modern medical research has proved that there is a subtle connection between the nasal cavity and the brain,and the complex and ingenious structure of the nasal cavity provides the possibility for drugs delivery to the brain through the nose. Drug administration through nasal cavity has obvious advantages in treatment of central nervous system diseases represented by ischemic stroke. Nasal administration is characterized by non-invasion,low infection,rapid absorption and brain targeting. The author will expound the theoretical basis of brain targeting of nasal administration from the aspects of anatomy and physiology,and summarize the transport pathway of drugs through the nose into the brain,the in vitro and in vivo experimental research basis of the " nose-brain"pathway,and the clinical nasal administration of traditional Chinese medicine to prevent cerebral ischemia. It provides a reference for better research of drugs to prevent and treat cerebral ischemia injury through the " nose-brain"pathway and lays a foundation for further research of the " nose-brain" pathway.

Abstract
Depression is a highly prevalent mental disease and increasingly become a global public health problem. Recent studies have shown that the dysfunction of liver was associated with depression. However, the previous studies have not been fully explained the relationship between depression and liver injury. The present study was aimed to investigate whether chronic liver injury could induce depressive-like behavior. Chronic liver injury was induced by intraperitoneal injection of carbon (CCl4), D-galactosamine (D-GalN) and thioacetamide (TAA), respectively. And the results showed that the serum activities of ALT in CCl4, D-GalN and TAA groups were significantly increased in both male and female mice compared with the control group, while the activities of AST increased only in CCl4 group. Meanwhile, H&E staining showed that CCl4, D-GalN and TAA induced hepatocytes injury in both male and female mice. Moreover, the sucrose preference was significantly decreased and the immobility time in forced swimming test and tail suspension test were significantly prolonged in CCl4 and D-GalN group compared with control group. Our findings demonstrated that chronic liver injury induced by CCl4 and D-GalN could induce depressive-like behaviors in mice.

Abstract
Icariin is a prenylated flavonol glycoside isolated from Epimedium herb, and has been shown to be its main bioactive component. Recently, the antidepressant-like mechanism of icariin has been increasingly evaluated and demonstrated. However, there are few studies that have focused on the involvement of the phosphatidylinositol 3-kinase (PI3K)/serine-threonine protein kinase (AKT) signaling in mediating the perimenopausal depression effects of icariin. Perimenopausal depression is a chronic recurrent disease that leads to an increased risk of suicide, and poses a significant risk to public health. The aim of the present study was to explore the effect of icariin on the expression of the PI3K-AKT pathway related to proteins in a rat model of perimenopausal depression. Eighty percent of the left ovary and the entire right ovary were removed from the model rats. A perimenopausal depression model was created through 18 days of chronic unpredictable stimulation, followed by the gavage administration of target drugs for 30 consecutive days. We found that icariin administered at various doses significantly improved the apparent symptoms in the model rats, increased the organ indices of the uterus, spleen, and thymus, and improved the pathological changes in the ovaries. Moreover, icariin administration elevated the serum levels of female hormone estradiol (E2), testosterone (T), and interleukin (IL)-2, decreased those of follicle stimulating hormone (FSH) and luteotropic hormone (LH), promoted the expression levels of estrogen receptor (ER) and ERα in the hypothalamus, and increased those of serotonin (5-HT), dopamine (DA), and noradrenaline (NA) in the brain homogenate. Furthermore, icariin elevated the expression levels of AKT, phosphorylation-akt (p-AKT), PI3K (110 kDa), PI3K (85 kDa), and B-cell lymphoma 2 (Bcl-2) in the ovaries, and inhibited those of Bax. These results show that icariin administration rebalanced the disordered sex hormones in perimenopausal depression rats, regulated the secretion of neurotransmitters in the brain, boosted immune function, and improved the perimenopausal syndrome. The mechanism of action may be related to the regulation of the expression of PI3K-AKT pathway-related proteins.

Abstract
Objective: To analyze the spatial-temporal characteristics of other infectious diarrhea (OID) in Jiangsu province from 2010 to 2017, and to provide evidence for setting up prevention and control programs of the disease. Methods: Data was from the Chinese Center for Disease Control and Prevention and the Statistics Bureau of Jiangsu province. Descriptive methods were used to illustrate the epidemiological characteristics of OID from 2010 to 2017. Global autocorrelation statistics method (Moran's I) was used to detect the spatial autocorrelation of OID, annually. Kulldorff M spatiotemporal scan statistics was used to analyze the spatial-temporal clustering of OID. ArcGIS 10.0 software, SaTScan 9.4 software and Excel 2017 software were also applied. Results: A total of 126 341 OID cases were found in Jiangsu province from 2010 to 2017 with an average annual incidence as 19.96/100 000. Children under five accounted for 55.08% (69 590/126 341) of the total cases. Obvious seasonal backshift with the increasing trends of the OID was noticed. There appeared four areas with high incidence of OID in the whole province, including Wuxi, Suzhou, Yancheng and Xuzhou. OID showed positive spatial autocorrelation at the county level with higher Moran's I from 0.19 to 0.33 (P<0.01). There appeared four positive clusters, all occurred in the high incidence period of OID, including the cluster area from the intersection areas of Changzhou and Wuxi (RR=7.61, LLR=2 605.80, P<0.01), respectively. Conclusion: With the increasing trends and the seasonal backshift of OID cases, pathogen surveillance programs set for those scattered children under five, in clustered regions and epidemic seasons should be strengthened.

Abstract
OBJECTIVE To explore the role of Ter cells in the development of the collagen-induced arthritis (CIA), we detected their quantity changes in the spleen of different stages of CIA mice and analyzed the correlation between Ter cells and the joint scores, and we also analyzed the correlation between Ter cells and the frequencies of T and B cell subsets, so as to further understand the pathogenesis of rheumatoid arthritis. METHODS The six to eight weeks DBA/1 mice were used to prepare CIA model. After the second immunization, we began to evaluate the joint score. According to the time of CIA onset and the joint score, the CIA mice were divided into three stages: early, peak and late stages. According to the final joint score, the CIA mice at the peak stage were subdivided into the high score group (score>8) and the low score group (score≤8). The frequencies of Ter cells in the spleen of the naïve mice and the CIA mice at various stages and the frequencies of T and B cell subsets in the spleen of the CIA mice at the peak stage were detected by flow cytometry, then we carried on the correlation analysis. RESULTS The frequencies of Ter cells in the spleen of the CIA mice was significantly higher than those of the naïve mice (8.522%±2.645% vs. 1.937%±0.725%, P<0.01), the frequencies of Ter cells in the spleen of the high score group mice was significantly lower than those of the low score group (6.217%±0.841% vs. 10.827%±0.917%, P<0.01). The frequencies of Th1 cells in the spleen of the high score group mice was significantly higher than those of the low score group mice (1.337%±0.110% vs. 0.727%±0.223%, P<0.05). The frequencies of Th17 cells in the spleen of the high score group mice was higher than those of the low score group mice (0.750%±0.171% vs. 0.477%±0.051%, P=0.099). The frequencies of germinal center B cells in the spleen of the high score group mice was significantly higher than those of the low score group mice (1.243%±0.057% vs. 1.097%±0.015%, P<0.05). Correlation analysis results showed that the frequencies of Ter cells in the spleen of the CIA mice at the peak stage was strongly negatively correlated with the frequencies of CD4+ T, Th1, Th17, and germinal center B cells, and was strongly positively correlated with the frequencies of B10 cells, indicating that these cells might have a protective effect in CIA. Studies on dynamic changes showed that the frequencies of Ter cells in the spleen of the CIA mice at the late stage was significantly lower than those at the peak stage (0.917%±0.588% vs. 8.522%±2.645%, P<0.001), suggesting the protective effect of these cells in arthritis. CONCLUSION Ter cells were significantly increased in the spleen of the CIA mice at peak stage, and were negatively correlated with joint scores and pathogenic immune cells, and positively correlated with protective immune cells. Ter cells were significantly decreased in the spleen of the CIA mice at the late stage. What we mentioned above suggests that Ter cells might be involved in the progression of rheumatoid arthritis as an immunomodulatory cell,but further in vivo and in vitro experiments are needed to verify its specific effects and mechanism.

Abstract
BACKGROUND Obesity and depression both individually contribute to the risk of Type II Diabetes (T2DM). The extent to which obesity can be set-off by depression is unknown. METHODS In a sample of 9340 participants followed for 15.4 years (79,372 person-years) from the prospective MONICA/KORA population-based cohort conducted in Southern Germany, we investigated the impact of obesity, defined as Body Mass Index (BMI) ≥ 30, and depression on the incidence of T2DM using Cox Proportional Hazards Regression. RESULTS The relative risk of T2DM was over 6 fold higher among obese participants in comparison to normal weight participants (HR 6.05; 95% CI 4.82 to 7.59; p < .0001). Nonetheless, among participants with obesity, comorbidity of depression was associated with an additional 2 fold risk T2DM (HR 8.05, 95% CI 5.90-10.98; p < .0001). This finding corresponded to an increase in the 15.4-year absolute risk of T2DM from 15.9 cases per 1000 person-years (py) in participants with obesity but not depression, to 21.4 cases per 1000 py for participants with obesity and depression. Further analysis of joint effects and Relative Excess Risk due to Interaction disclosed that depressed mood is associated with significantly higher risk of T2DM in participants with obesity, and to a lesser extent in overweight participants, however an association was not found in normal weight participants. CONCLUSIONS The present investigation discloses that despite the overreaching importance of obesity as a risk factor for T2DM, there is room for depressed mood to add measurable risk prediction.

Abstract
Secondary injury of brain tissue following cerebral infarction exhibits a complicated pathogenesis that is attributed to the induction of apoptosis and inflammatory response. The present study aimed to investigate the polydatin neuroprotective effects and their mode of action in cerebral ischemic injury. A total of 80 healthy adult male Sprague-Dawley rats were randomly divided into a Sham operated group, a permanent middle cerebral artery occlusion (MCAO) group, a Polydatin low dose group and a Polydatin high dose group. A total of 20 rats were used in each group. The right MCAO model of rats was established using the modified Longa suture method. The animals in the intervention group were injected intraperitoneally with 12.5mg/kg and/or 50mg/kg of polydatin following infarction. The expression levels of p53 and Notch 1 were measured by immunohistochemical techniques. The degree of left limb hemiplegia in the MCAO group was different compared with that of the low and high dose group of polydatin. The score for the neurological function in the high-dose group of polydatin was lower than that in the MCAO group (High vs MCAO: 2.4±0.31 vs 3.9±0.23, P less than0.05). The results indicated that high dose polydatin could reduce brain edema following cerebral infarction and improve the behavioral score in rats.

Abstract
Biodegradable magnesium-calcium (MgCa) alloy is a very attractive orthopedic biomaterial compared to permanent metallic alloys. However, the critical issue is that MgCa alloy corrodes too fast in the human organism. Compared to dry cutting, the synergistic dry cutting-finish burnishing can significantly improve corrosion performance of MgCa0.8 (wt%) alloy by producing a superior surface integrity including good surface finish, high compressive hook-shaped residual stress profile, extended strain hardening in subsurface, and little change of grain size. A FEA model was developed to understand the plastic deformation of MgCa materials during burnishing process. The measured polarization curves, surface micrographs, and element distributions of the corroded surfaces by burnishing show an increasing and uniform corrosion resistance to simulated body fluid.

Abstract
The development of medicine experienced a long history, and the origin of medicine is not appeared overnight. Due to the lack of historical data, the question of the origin of medicine has not been agreed upon. As an ancient primitive religion, Shamanism retains the use of hallucinogenic drugs in its early religious activities rather well, providing a guidance for exploring the cognition on drugs in early human. Through the review of the hallucinogenic plants used by shaman religious activities in different countries and areas, it was found that hallucinogenic drugs can be classified into two categories: single and mixed, which came mainly from plants and fungi, and the origin of hallucinogenic drugs has a high fitting degree with Shaman location. The study result suggests that, based on the worldwide research literature on the application of such hallucinogens with local characteristics in the shamanistic religious activities, it is very likely that important clues can be found to understand the facts of discovery and application of natural drugs, thus providing a new approach for the studies on the origin of drugs.

Abstract
Objective: To summarize the clinical manifestation and molecular characteristics of COQ6 mutation induced nephrotic syndrome, and to evaluate efficacy of CoQ(10) therapy. Method: Clinical data of the case with infantile nephrotic syndrome was summarized, including clinical manifestations, laboratory findings and family investigation. The patient received CoQ(10) 30 mg/(kg·d) therapy. Urine protein/creatinine ratio, serum albumin and creatinine were detected to assess the efficacy of the therapy. Result: (1) The 10 months old boy was presented with nephrotic level proteinuria and hypoalbuminemia. Extra-renal manifestations included cardiovascular abnormality, motor and mental retardation and unilateral ptosis. The patient had no consanguinity. A novel homozygous p. R360W mutation in COQ6 gene was identified and confirmed by next-generation sequencing and Sanger sequencing, respectively. Family analysis showed that homozygous p. R360W mutation in COQ6 gene was inherited from his parents. Missense p. R360W mutation was damaging by prediction online PolyPhen and SIFT software. After 2 months of CoQ(10) complementary therapy, the patient's urine protein/creatinine ratio declined from 7.2 to 1.3, and decreased further to 0.01 mg/mg with normal albumin level and renal function within 3 months. Nephropathy remission was maintained and growth retardation improved significantly during the last follow-up. Nevertheless, the patient manifested with sensorineural deafness at the age of 2 years. (2) There were 6 different mutations in coenzyme Q(10) biosynthesis monooxygenase 6 (COQ6) in 13 individuals from 7 families by homozygosity mapping in the whole world. Each mutation was linked to early-onset SRNS with sensorineural deafness. Renal biopsy revealed FSGS in 7 cases and DMS in 1 case. Other manifestations included ataxia, seizures, facial dysmorphism, nephrolithiasis and growth retardation. Four patients received CoQ(10) supplementation and responded to the treatment. Conclusion: Renal disease caused by recessive COQ6 gene mutation was nephrotic syndrome. The patient benefited from early CoQ(10) complement and reached nephropathy remission.

Abstract
Based on the clinical symptom characteristics of transient ischemic attack in Chinese and Western medicines, the existing models of transient ischemic attack were summarized and analyzed. Then the advantages and disadvantages of each model, the diagnostic criteria of traditional Chinese and Western medicine and clinical symptoms compliance were analyzed to put forward the evaluation method and improvement method of the corresponding animal models. It was found that there were many modeling methods of transient ischemic attack, but they can not reflect the transience, reversibility, recurrence and other typical characteristics of the disease, with significant differences with clinical symptoms. Moreover, there is lack of reasonable quantitative criteria for the success of the animal model. By combining the existing single factor animal models, a composite animal model that was more closely related to the clinical symptoms of transient ischemic attack was established to replicate an animal model that was more compatible with the characteristics of clinical symptoms. It is the future development directions of the transient ischemic attack animal models to establish reasonable quantitative standards, reflect the causes of Chinese and Western medicine symptoms and improving a series of systematic and complete model evaluation methods.

Abstract
OBJECTIVE During an acute myocardial infarction, patients often use denial as a coping mechanism which may provide positive mood regulating effects but may also prolong prehospital delay time (PHD). However, empirical evidences are still sparse. METHODS This cross-sectional study included 533 ST-elevated myocardial infarction (STEMI) patients from the Munich Examination of Delay in Patients Experiencing Acute Myocardial Infarction (MEDEA) study. Data on sociodemographic, clinical and psycho-behavioral characteristics were collected at bedside. The outcome was assessed using the Cardiac Denial of Impact Scale (CDIS) with the median split as cutoff point. A total of 206 (41.8%) STEMI patients were thus classified as deniers. RESULTS Deniers were less likely to suffer from major depression (p=0.04), anxiety (p=0.01) and suboptimal well-being (p=0.01) compared to non-deniers during the last six months prior to STEMI. During STEMI, they were less likely to perceive severe pain strength (p=0.04) and racing heart (p=0.02). Male deniers were also less likely to perceive shortness of breath (p=0.03) and vomiting (p=0.01). Denial was not associated with overall delay time. However, in the time window of 3 to 24h, denial accounted for roughly 40min extra delay (356 vs. 316.5min p=0.02 n=196). CONCLUSIONS Denial not only contributes to less suffering from acute heart related symptoms and negative affectivity but also leads to a clinically significant delay in the prevalent group.

Abstract
Chronic glucocorticoid exposure is known to cause depression and metabolic disorders. It is critical to improve abnormal metabolic status as well as depressive-like behaviors in patients with long-term glucocorticoid therapy. This study aimed to investigate the effects of resveratrol on the depressive-like behaviors and metabolic abnormalities induced by chronic corticosterone injection. Male ICR mice were administrated corticosterone (40 mg/kg) by subcutaneous injection for three weeks. Resveratrol (50 and 100 mg/kg), fluoxetine (20 mg/kg) and pioglitazone (10 mg/kg) were given by oral gavage 30 min prior to corticosterone administration. The behavioral tests showed that resveratrol significantly reversed the depressive-like behaviors induced by corticosterone, including the reduced sucrose preference and increased immobility time in the forced swimming test. Moreover, resveratrol also increased the secretion of insulin, reduced serum level of glucose and improved blood lipid profiles in corticosterone-treated mice without affecting normal mice. However, fluoxetine only reverse depressive-like behaviors, and pioglitazone only prevent the dyslipidemia induced by corticosterone. Furthermore, resveratrol and pioglitazone decreased serum level of glucagon and corticosterone. The present results indicated that resveratrol can ameliorate depressive-like behaviors and metabolic abnormalities induced by corticosterone, which suggested that the multiple effects of resveratrol could be beneficial for patients with depression and/or metabolic syndrome associated with long-term glucocorticoid therapy.

Abstract
OBJECTIVE To explore the feasibility and clinical significance of pediatric renal transplantation using organ donations from pediatric patients donors. METHOD Clinical data of children who underwent renal transplantation using organ donations from pediatric patients between September 2011 and December 2014 were retrospectively analyzed, including diagnosis and treatment before transplant, transplant operation, immunosuppression, complication and prognosis. RESULT Totally 39 cases received pediatric organ donation-pediatric kidney transplantation. The median age at transplantation was 10.5 years. Before transplantation, 37 cases received chronic dialysis. The median waiting time for transplantation was 15 months. The 39 cases received kidneys from 29 donors who were aged from 9 days to 7 years (median 13 months). The median duration of follow-up after the transplantation was 19 months. At 3 month after transplantation and latest follow-up, the length of graft increased (11.3±6.4) mm and (17.5±10.8) mm, respectively. At 6 month and 12 month after transplantation, the height of the recipients increased (5.8±3.5) cm and (15.0±3.5) cm, respectively. At latest follow-up, the serum creatinine level was (80.3±31.9) μmol/L and the eGFR was (94.4±32.9) ml/(min·1.73 m(2)). The recipient survival rate was 100% and grafts survived in 34 cases; 3 cases lost graft function due to thrombosis of renal vessels and the other 2 cases due to bleeding and chronic allograft nephropathy. Donor age of less than 12 months carried higher risk of thrombosis/hemorrhagic complication (P=0.042) and graft dysfunction (P=0.017). CONCLUSION Favorable outcome can be obtained from pediatric organ donation-pediatric kidney transplantation. Patient survival rate reached 100% at one-year and three-year graft survival rate was 87%. The size of the allograft would increase and the height of the recipients would improve after transplantation.

Abstract
BACKGROUND Idiopathic nephrotic syndrome is the most common glomerular disease in children. This study was undertaken to observe the efficacy and side-effects of rituximab (RTX) in treating children with different types of refractory primary nephrotic syndrome. METHODS Twelve patients with steroid dependent nephrotic syndrome (SDNS), frequently relapsing nephritic syndrome (FRNS), and steroid resistant nephrotic syndrome (SRNS) were enrolled in our study. There were obvious drug side-effects, and proteinuria remained difficult to control. RTX was administered at a dose of 375 mg/m(2) body surface area, once or twice weekly. RESULTS The male to female ratio was 3:1, and the onset age was 1.6-8.9 years. There were 9 patients with steroid sensitive nephrotic syndrome (SDNS or FRNS), and 3 patients with SRNS. There were 7 patients with minimal change disease (MCD), 3 patients with focal segmental glomerular sclerosis (FSGS), 1 with focal proliferative glomerulonephritis, and 1 without renal biopsy. The total effective treatment rate of RTX was 91.67%, and for 77.78% of the patients, steroid dosage could be reduced. Six months before and after RTX infusion, the mean steroid dosage was significantly decreased (P=0.014) and the recurrence number was significantly reduced (P<0.001). The results were better in MCD patients than in FSGS patients (P=0.045). There was no significant difference between FRNS/SDNS and SRNS patients (P=0.175). During RTX administration, 3 patients developed skin rashes, 1 developed hypotension, and 1 developed a fever. One patient experienced a persistent decrease in serum immunoglobulin level but without serious infection. CONCLUSION RTX was effective in the treatment of refractory nephrotic syndrome, and it could significantly reduce the use of steroid and immunosuppressants.

Abstract
We studied a case of recurrent PV-B19-associated anemia in a renal transplant child with long-term remission induced by baseline immunosuppression adjusted and intensive IVIG therapy. This was a 15-yr-old boy. Seven wk after transplantation, he experienced acute rejection, which was treated with high-dose steroids, ATG, and plasmapheresis. Ten wk after transplantation (three wk after rejection), his hemoglobin dropped to 54 g/L and serum PV-B19 PCR was positive. After therapy with IVIG and conversion from mycophenolate mofetil to rapamycin, anemia resolved. But the patient had fever on the fourth day of IVIG with mild pulmonary edema and rise in serum creatinine. Two months after the first course of IVIG, anemia recurred and a second course of IVIG (preadministration methylprednisolone) was given, which was followed by the resolution of anemia without side effect and recurrence two months later again. Baseline immunosuppression was adjusted with dual immunosuppression and low doses including prednisolone and tacrolimus. At the same time, monthly course of IVIG was repeated four times. Within the next 23 months, anemia did not recur and renal function remained stable. In conclusion, PV-B19-associated anemia can be recurrent in immunocompromised children and baseline immunosuppression should be carefully adjusted to control PV-B19 infection.

Abstract
Snow lotus (Saussurea involucrata (Kar. & Kir.) Sch. Bip.) is an economically important medicinal herb increasingly grown in China in recent years. During the summer and autumn of 2005, 2006, and 2007, a necrosis of unknown etiology was observed on leaves in commercial production areas in Xinjiang Province of China. Disease incidence was approximately 40 to 50% of the plants during the 2005 and 2007 growing seasons. Initial symptoms consisted of pronounced water-soaked, dark brown-to-black spots that were 1 to 2 mm in diameter on young, expanding leaves. Later, some leaf spots on older leaves enlarged and coalesced, causing leaf desiccation. Leaf samples were collected in 2005, 2006, and 2007 from the affected hosts. Bacterial streaming was evident from these samples, and 28 strains were isolated on nutrient agar or King's medium B (KMB). All strains were gram negative and fluoresced bluegreen under UV light after 48 h of growth at 28°C on KMB. On the basis of LOPAT tests, the strains were identified as Pseudomonas syringae (1). The identity of two strains was confirmed by sequencing the 16S rDNA gene, which revealed 98% similarity to P. syringae strains in NCBI (Accession Nos. FJ001817 and FJ001818 for XJSNL 111 and 107, respectively). Infiltration of tobacco leaves with bacterial suspensions resulted in typical hypersensitivity reactions within 24 h. Pathogenicity of the strains was confirmed by spray inoculating five snow lotus leaves of a six-leaf stage plant with 108 CFU ml-1 bacterial suspensions in sterile water and five plants sprayed with sterile distilled water served as controls. Inoculated and sterile water-sprayed controls were maintained in the growth chamber with 90% relative humidity for 15 days at 15 ± 2°C. Symptoms similar to the original symptoms were observed on inoculated plants after 2 weeks. No symptoms developed on controls. Bacteria reisolated from inoculated plants were identified as strains of P. syringae. Isolates were deposited at the Key Laboratory for Oasis Crop Disease Prevention and Cure, Shihezi University. Rust caused by Puccinia carthami and leaf spot disease caused by Alternaria carthami of snow lotus have been reported (2,3). To our knowledge, this is the first report of P. syringae as the cause of bacterial leaf spot on snow lotus in China. References: (1) A. Braun-Kiewnick and D. C. Sands. Pseudomonas.

Abstract
PURPOSE To determine whether intravitreal irrigation with Ca(2+)-free and Mg(2+)-free BSS Plus (Alcon Laboratory, Fort Worth, Texas) solution alters the adhesiveness between the retinal pigment epithelium and the retina of rabbits. METHODS Thirty-four eyes of 34 Dutch pigmented rabbits underwent lensectomy and vitrectomy. Subsequently, the vitreous cavity of 24 eyes was irrigated with Ca(2+)-free and Mg(2+)-free BSS Plus solution for 10 or 20 minutes. The other 10 eyes were irrigated with BSS Plus solution for 20 minutes as controls. To determine the adhesiveness between the retinal pigment epithelium and retina, a retinal detachment was produced in 12 of the 34 eyes. The apical surface of the retinal pigment epithelium and the photoreceptor outer segments were examined by scanning electron microscopy. Retinal physiology was assessed by electroretinography and retinal morphology by light microscopy. RESULTS After retinal detachment was produced, the number of cone sheaths on the apical surface of the retinal pigment epithelium after irrigation with Ca(2+)-free and Mg(2+)-free BSS Plus solution for 20 minutes (33 +/- 15, mean +/- SD) was significantly less than the number of cone sheaths on the apical surface of the retinal pigment epithelium of eyes after irrigation with BSS Plus solution for 20 minutes (120 +/- 50) or the number of cone sheaths on the apical surface of the retinal pigment epithelium of eyes after 10 minutes of irrigation with Ca(2+)-free and Mg(2+)-free BSS Plus solution (115 +/- 49; P =.02). The b-wave amplitudes in the eyes irrigated with Ca(2+)-free and Mg(2+)-free BSS Plus solution for 20 minutes were depressed compared with the b-waves in eyes irrigated with BSS Plus solution for 20 minutes on the first postoperative day (P =.03). After the third postoperative day, there was no significant difference in the b-waves (P >.06). Light microscopy demonstrated no morphologic abnormalities after the use of both solutions. CONCLUSIONS Intravitreal irrigation with Ca(2+)-free and Mg(2+)-free BSS Plus solution for 20 minutes altered the adhesion between the retinal pigment epithelium microvilli and retinal outer segments and made the creation of retinal detachment less traumatic. These results suggest that Ca(2+)-free and Mg(2+)-free BSS Plus solution may be of clinical value for the creation of an intentional retinal detachment for foveal translocation surgery.
