ABSTRACT

Objective:To investigate the short-term efficacy and safety of albumin-bound paclitaxel combined with nedaplatin followed by concurrent radiotherapy in treatment of stage Ⅲ massive cervical cancer.Methods:The clinical data of 84 patients with massive cervical cancer admitted to Harbin Medical University Cancer Hospital from April 2019 to April 2020 were retrospectively analyzed. According to the different treatment regimens, patients were divided into the observation group and the control group, each with 42 cases. The observation group received albumin-bound paclitaxel combined with nedaplatin followed by concurrent radiotherapy, and the control group received solvent-based paclitaxel combined with nedaplatin followed by concurrent radiotherapy. The short-term efficacy and adverse reactions of the two groups were compared.Results:The partial remission (PR) rate of the observation group and the control group at 1 month of treatment was 92.9% (39/42) and 35.7% (15/42), respectively, and the difference was statistically significant ( χ2 = 29.867, P < 0.01). The complete remission (CR) rate of the observation group and the control group at 1 month after treatment was 59.5% (25/42) and 38.1% (16/42), respectively, and the difference was statistically significant ( χ2 = 3.859, P = 0.049). The incidence of diarrhea of the observation group was lower than that of the control group [33.33% (14/42) vs. 54.8% (23/42)], and the difference was statistically significant ( χ2 = 3.913, P = 0.048). There were no statistical differences in the incidence of hematological adverse reactions and abnormal liver and kidney functions between the two groups (all P > 0.05). Conclusion:The albumin-bound paclitaxel combined with nedaplatin followed by concurrent radiotherapy have a good short-term efficacy in treatment of stage Ⅲ massive cervical cancer, and the adverse reactions are tolerable.

ABSTRACT

Objective:To construct a simple, precise and personalized comprehensive nomogram for prediction the risk of multidrug-resistant tuberculosis (MDR-TB) and to evaluate its prediction value among individuals with previous tuberculosis history (PTBH).Methods:A matched case-control study (1∶2 ratios) was performed in 1 881 patients with PTBH treated in 12 designated tuberculosis hospitals in Hangzhou City between January 1, 2005 and December 31, 2019, and there were 1 719 patients in training set, and 162 in validation set. A multivariable Cox regression analysis was used to evaluate independent predictors for the incident of MDR-TB in individuals with PTBH. A comprehensive nomogram was developed based on the multivariable Cox model. The accuracy of the prediction was assessed using concordance index (C-index), calibration curve and area under the receiver operator characteristic (ROC) curve.Results:The nomogram constructed based on the multivariable Cox regression model incorporated 10 independent predictors of the risk of MDR-TB. A history of direct contact (grade 1, 0-100.0 points) ranked on the top of all risk factors, followed by duration of positive sputum culture (grade 2, 0-84.5 points), unfavorable treatment outcome (grade 3, 0-52.0 points), human immunodeficiency virus infection (grade 4, 0-48.5 points), retreated tuberculosis history (grade 5, 0-40.0 points), non-standardized treatment regimens of retreated tuberculosis (grade 6, 0-32.5 points), duration of pulmonary cavities (grade 7, 0-31.0 points), passive mode of tuberculosis case finding (grade 8, 0-25.0 points), age<60 years (grade 9, 0-17.5 points), and standard frequencies of chest X-ray examination (grade 10, 0-14.0 points). The C-indexes of this nomogram for the training and validation sets were 0.833 (95% confidence interval ( CI) 0.807-0.859) and 0.871 (95% CI 0.773-0.969), respectively, indicating that the nomogram had good fitting effect. The calibration curves for the risk of incident MDR-TB showed an optimal agreement between nomogram prediction and actual observation in the training and validation sets, respectively.The areas under ROC curve of the 1-year, 5-year, and 10-year MDR-TB risk probability of the training set were 0.904, 0.921, and 0.908, respectively, and those of the validation set were 0.954, 0.970, and 0.919, respectively. Conclusion:Through this nomogram model, clinicians could precisely predict the risk of incident MDR-TB among individuals with PTBH in the clinical practice.

ABSTRACT

Objective:To investigate the molecular mechanism of Qiyu Sanlong prescription (QYSL) in inhibiting the "addiction" of lung cancer A549 cells to miRNA21. Method:The human lung cancer A549 cells were routinely passaged and divided into the blank group, blank serum group, QYSL-containing serum group, and siRNA group. The prepared QYSL-containing serum was used for intervention, with the optimal concentration and action time determined in previous studies. The protein and mRNA expression levels of miRNA21 and related molecules in its target phosphatase and tensin homolog deleted on chromosome 10 (PTEN)/phosphatidylinositol 3-kinase (PI3K) signaling pathway were detected by real-time polymerase chain reaction (Real-time PCR) and Western blot assay. Result:The comparison with the blank serum group revealed that the mRNA expression levels of miRNA21 in the QYSL-containing serum group and the siRNA group were decreased, while the PTEN mRNA expression in the QYSL-containing serum group was increased, showing significant differences (<italic>P</italic><0.01). Compared with the blank serum, the QYSL-containing serum and siRNA significantly down-regulated PI3K and mammalian target of rapamycin (mTOR) mRNA expression (<italic>P</italic><0.01), whereas the QYSL-containing serum did not change the mRNA expression of protein kinase B (Akt). The protein expression levels of PTEN in the QYSL-containing serum group and the siRNA group were obviously elevated in contrast to that in the blank serum group (<italic>P</italic><0.05). Meanwhile, the protein expression levels of phosphorylated Akt (p-Akt) and phosphorylated mTOR (p-mTOR) evidently declined in the QYSL-containing serum group (<italic>P</italic><0.05), but there was no significant reduction in total Akt and mTOR protein expression. The PI3K protein expression was slightly down-regulated, with no statistical significance. Conclusion:QYSL inhibits the transcription of miRNA21, increases the expression of PTEN, and reduces the expression of key molecules in PI3K/Akt/mTOR signaling pathway, thus mildly inhibiting the "addiction" of lung cancer cells to oncogenes and blocking their proliferation.

ABSTRACT

Objective:To evaluate the efficacy and long-term effect of functional electrical stimulation (FES) on cerebral palsy. Methods:Literature retrieval was carried out in the electronic databases of PubMed, Embase, Web of Science, Cochrane Library, China Biology Medicine Disc (CBM), CNKI, Wanfang Database and VIP. The time limit was from the establishment of these databases to March 26th, 2020. According to the inclusion and exclusion criteria, randomized controlled trials about FES for children with cerebral palsy were included. At least two evaluators extracted the data independently and used Cochrane 5.1.0 bias risk assessment tool to evaluate the quality of included studies. The data was analyzed with Review Manager 5.3 software. Results:A total of eleven studies with 513 children were included. The Gross Motor Function Measure-88 (GMFM-88) D/E scores (MD = 8.14, 95%CI 6.26 to 10.02, P < 0.001), GMFM-88 B score (MD = 8.77, 95%CI 4.00 to 13.53, P < 0.001), modified Ashworth Scale (MAS) score (MD = -1.05, 95%CI -1.25 to -0.84, P < 0.001), Kyphosis angle (MD = -10.67, 95%CI -12.21 to -9.13, P < 0.001), Cobb's angle (MD = -2.66, 95%CI -3.38 to -1.93, P < 0.001), step length (MD = 3.35, 95%CI 1.81 to 4.90, P < 0.001), walking speed (MD = 0.09, 95%CI 0.05 to 0.14, P < 0.001) and GMFM score at six weeks follow-up (MD = 4.84, 95%CI 1.90 to 7.77, P = 0.001) were better in FES group than in the control group. There was no significant difference in MAS score between two groups after six weeks of follow-up (MD = 0.04, 95%CI -0.30 to 0.37, P = 0.84). Conclusion:FES could improve the lower-limb and trunk function of children with cerebral palsy, however, the long-term effect of relieving muscle spasm was not significant.

ABSTRACT

Objective:To observe the effect of Qiyu Sanlong decoction (QYSL) on the expressions of key molecules in signal axis of mammalian rapamycin target protein (mTOR)/yeast Atg6 homologous (Beclin1)/ microtubule-associated protein1 light chain3 (LC3) in A549 cells. Method:With A549 cells as the research object, the effect of QYSL medicated serum on cell viability of A549 cells were detected by cell counting kit-8 (CCK-8) method. The effect of QYSL decoction on A549 cell apoptosis, autophagosome formation and the expression of autophagy markers were detected by Terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) method, transmission electron microscope (TEM), Real-time polymerase chain reaction (Real-time PCR) and Western blot. Result:QYSL medicated serum could inhibit the viability of A549 cells in a concentration-dependent manner. Compared with the blank serum group, the number of apoptotic A549 cells in the QYSL medicated serum group was significantly increased (P<0.01), and the formation of autophagosome was significantly increased. Compared with the blank serum group, the mRNA and protein expressions of mTOR in A549 cells in the QYSL serum group were significantly decreased (P<0.01), while mRNA and protein expressions of Beclin-1, autophagy related genes 5 (ATG5), autophagy related genes 13 (ATG13) were significantly increased (P<0.01). Conclusion:QYSL decoction can induce autophagy in A549 cells, and its specific mechanism may be related to the down-regulation of mTOR expression, the up-regulation of Beclin1, ATG5, ATG13 and LC3 expression, and the promotion of LC3Ⅰ conversion to LC3Ⅱ.

ABSTRACT

This study aims to investigate metabolic activities of psoralidin in human liver microsomes( HLM) and intestinal microsomes( HIM),and to identify cytochrome P450 enzymes( CYPs) and UDP-glucuronosyl transferases( UGTs) involved in psoralidin metabolism as well as species differences in the in vitro metabolism of psoralen. First,after incubation serial of psoralidin solutions with nicotinamide adenine dinucleotide phosphate( NADPH) or uridine 5'-diphosphate-glucuronic acid( UDPGA)-supplemented HLM or HIM,two oxidic products( M1 and M2) and two conjugated glucuronides( G1 and G2) were produced in HLM-mediated incubation system,while only M1 and G1 were detected in HIM-supplemented system. The CLintfor M1 in HLM and HIM were 104. 3,and57. 6 μL·min~(-1)·mg~(-1),respectively,while those for G1 were 543. 3,and 75. 9 μL·min~(-1)·mg~(-1),respectively. Furthermore,reaction phenotyping was performed to identify the main contributors to psoralidin metabolism after incubation of psoralidin with NADPH-supplemented twelve CYP isozymes( or UDPGA-supplemented twelve UGT enzymes),respectively. The results showed that CYP1 A1( 39. 5 μL·min~(-1)·mg~(-1)),CYP2 C8( 88. 0 μL·min~(-1)·mg~(-1)),CYP2 C19( 166. 7 μL·min~(-1)·mg~(-1)),and CYP2 D6( 9. 1 μL·min~(-1)·mg~(-1)) were identified as the main CYP isoforms for M1,whereas CYP2 C19( 42. 0 μL·min~(-1)·mg~(-1)) participated more in producing M2. In addition,UGT1 A1( 1 184. 4 μL·min~(-1)·mg~(-1)),UGT1 A7( 922. 8 μL·min~(-1)·mg~(-1)),UGT1 A8( 133. 0 μL·min~(-1)·mg~(-1)),UGT1 A9( 348. 6 μL·min~(-1)·mg~(-1)) and UGT2 B7( 118. 7 μL·min~(-1)·mg~(-1)) played important roles in the generation of G1,while UGT1 A9( 111. 3 μL·min~(-1)·mg~(-1)) was regarded as the key UGT isozyme for G2. Moreover,different concentrations of psoralidin were incubated with monkey liver microsomes( MkLM),rat liver microsomes( RLM),mice liver microsomes( MLM),dog liver microsomes( DLM) and mini-pig liver microsomes( MpLM),respectively. The obtained CLintwere used to evaluate the species differences.Phase Ⅰ metabolism and glucuronidation of psoralidinby liver microsomes showed significant species differences. In general,psoralidin underwent efficient hepatic and intestinal metabolisms. CYP1 A1,CYP2 C8,CYP2 C19,CYP2 D6 and UGT1 A1,UGT1 A7,UGT1 A8,UGT1 A9,UGT2 B7 were identified as the main contributors responsible for phase Ⅰ metabolism and glucuronidation,respectively. Rat and mini-pig were considered as the appropriate model animals to investigate phase Ⅰ metabolism and glucuronidation,respectively.

ABSTRACT

BACKGROUNDS@#Cancer is one of the main causes of death worldwide, seriously threatening human health and life expectancy. We aimed to analyze the cancer incidence and mortality rates during 2016 in Zhejiang Province, Southeast China.@*METHODS@#Data were collected from 14 population-based cancer registries across Zhejiang Province of China. Cancer incidence and mortality rates stratified by sex and region were analyzed. The crude rate, age-standardized rate, age-specific and region-specific rate, and cumulative rate were calculated. The proportions of 10 common cancers in different groups and the incidence and mortality rates of the top five cancers in different age groups were also calculated. The Chinese national census of 2000 and the world Segi population was used for calculating the age-standardized incidence and mortality rates.@*RESULTS@#The 14 cancer registries covered a population of 14,250,844 individuals, accounting for 29.13% of the population of Zhejiang Province. The total reported cancer cases and deaths were 55,835 and 27,013, respectively. The proportion of morphological verification (MV%) was 78.95% of the population, and percentage of incident cases identified through death certificates only (DCO%) was 1.23% with a mortality-to-incidence ratio (M/I ratio) of 0.48. The crude incidence rate in Zhejiang cancer registration areas was 391.80/105; the age-standardized incidence rate of the Chinese standard population (ASIRC) and the age-standardized incidence rate of the world standard population (ASIRW) were 229.76/105 and 220.96/105, respectively. The incidence rate in men was higher than that in women. The incidence rate increased rapidly after 45 years of age and peaked in individuals aged 80 to 84 years. The top 10 incidence rates of cancers were lung cancer, female breast cancer, thyroid cancer, colorectal cancer, stomach cancer, liver cancer, prostate cancer, cervical cancer, esophageal cancer, and pancreatic cancer (from highest to lowest). The crude mortality rate in Zhejiang cancer registration areas was 189.55/105; the age-standardized mortality rate of the Chinese standard population (ASMRC) and the age-standardized mortality rate of the world standard population (ASMRW) were 94.46/105 and 93.42/105, respectively. The mortality rate in men was higher than that in women, and the male population in rural areas was higher than that in urban areas. The cancer mortality rate increased rapidly after 50 years of age and peaked in individuals aged 85+ years. The top 10 mortality rates of cancers were lung cancer, liver cancer, stomach cancer, colorectal cancer, pancreatic cancer, esophageal cancer, female breast cancer, prostate cancer, lymphoma, and leukemia (from highest to lowest).@*CONCLUSIONS@#Lung cancer, female breast cancer, thyroid cancer, colorectal cancer, prostate cancer, liver cancer, and stomach cancer were the most common cancers in Zhejiang Province. Effective prevention and control measures should be established after considering the different characteristics of cancers in urban and rural areas.

ABSTRACT

Objective:To analyze the changes in T lymphocyte subsets, B lymphocytes and NK cells in children with active tuberculosis (TB) and their clinical significance.Methods:T lymphocyte subsets, B lymphocytes and NK cells in peripheral blood samples of 106 patients with acute TB (TB group) and 106 healthy children (healthy control group) were detected by flow cytometry and compared between different groups.Results:The percentages of CD3 + T, CD4 + T and NK cells as well as the CD4 +/CD8 + T cell ratio were significantly lower in the TB group than in the healthy control group ( Z=-3.783, P=0.000; Z=-5.401, P=0.000; Z=-3.434, P=0.001; Z=-2.014, P=0.044). The percentages of double negative T (DNT) and B cells in the TB group were significantly higher than those in the healthy control group ( Z=2.765, P=0.006; Z=6.880, P=0.000). No significant difference in the percentage of CD8 + T or double positive T (DPT) cells was observed between the two groups ( P>0.05). The expression of peripheral lymphocyte subsets varied in TB children of different age groups (0-<3, 3-<6, 6-<10 and 10-<16 years old). There were significant differences in CD3 + T, DNT and B cells among the four age groups ( H=10.081, P=0.018; H=14.583, P=0.002; H=8.498, P=0.037). The percentage of CD4 + T cells was significantly lower in children with extrapulmonary TB than in those with pulmonary TB ( Z=-3.068, P=0.002). No statistically significant difference in other lymphocyte subsets was found between children with extrapulmonary and pulmonary TB ( P>0.05). Conclusions:Tuberculosis could lead to immune dysfunction in children. Dynamic monitoring of the changes in peripheral lymphocyte subsets in children with TB could be conducive to better assessment of immune status and providing personalized treatment.

ABSTRACT

Objective:To evalte a novel laparoscopic splenic artery ligation plus devascularization (LSALD) vs. laparoscopic splenectomy and devascularization (LSD) for the treatment of portal hypertention. Methods:From Jan 2014 to Dec 2019, 50 patients undergoing LSALD and 30 patients receiving LSD . We compared the safety and feasibility between LSALD and LSD groups by analyzing the patients′ blood routine, liver function before and after operation, intraoperative condition, postoperative recovery and prognosis.Results:The operation time[(181±72)min vs.(284±72)min , t=-6.205, P<0.01], intraoperative blood loss[(100±50)ml vs.( 700±86 ml), t=-5.166, P<0.01]and blood transfusion rate (28% vs.67%, χ 2=11.471, P<0.01)in LSALD group were significantly more favorite than those in LSD group ( P<0.05). The postoperative exhaust in the LSALD group was earlier than that in the LSD group (2 d vs.3 d, Z=2.361, P<0.05) though the WBC and blood platelet count was higher in LSD group ( P<0.05). Portal vein thrombosis occurred in 10 cases in LSD group and 6 cases in LSALD group (χ 2=5.757, P<0.05). Conclusion:Compared with laparoscopic splenectomy combined with periesophagogastric devascularization, laparoscopic splenic artery ligation combined with periesophagogastric devascularization is less traumatic, helping quick recovery and lower rate of post-op portal vein thrombosis.

ABSTRACT

Objective:To investigate the expression of transcription factor SOX11 in retinoblastoma(RB) and the relation with the genes and cellular pathways.Methods:A public data set gse59983 containing the full mRNA expression profile of cancer tissues in 76 RB patients was downloaded from the GEO Database at the National Center for Biotechnology Information. According to the expression of 15 marker genes, these genes were divided into cell cycle marker genome (group 1, 26 patients), vertebral photoreceptor marker genome(group 2, 4 patients) and rod photoreceptor marker gene (group 3, 46 patients). R2 bioinformatics platform(http://r2.amc.NL) was used to analyze the gse59983 public data set. The SOX11 expression in cancer tissues of patients in 3 groups were observed and the SOX11-related genes were identified. According to the gene correlation, the clustering heat map was drawn, and the related genes and pathways of SOX11 were preliminarily analyzed by Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis tool and Gene Annotation (GO) analysis method.Results:SOX11 expression in cancer tissues of patients in group 1 was significantly higher than that of groups 2 and 3 ( P<0.001). SOX11 expression in cancer tissues of patients in group 3 was significantly higher than that in group 2 ( P<0.001). A total of 4524 genes significantly related to SOX11 expression were detected. Among them, there were 2139 positively correlated genes and 2385 negatively correlated genes. SOX11 and the 16 genes with the strongest correlation were screened and the clustering heat map was drawn. The clustering form of SOX11 and SOX11 significantly correlated genes was roughly the same as the original form. KEGG and GO analysis showed that SOX11 related genes were involved in regulating mitotic cell cycle, cell apoptosis, photoreceptor cell development, photoreceptor cell protection, etc. Conclusion:The expression of SOX11 in RB is significantly different in different types or periods. Its expression is significantly correlated with genes involved in the regulation of cell cycle.

ABSTRACT

Objective:To analyze the epidemiological characteristics of respiratory syncytial virus (RSV)-caused respiratory diseases in children in Hebei Province and the changes in peripheral blood lymphocyte subsets and inflammatory indexes.Methods:A total of 9 491 sputum specimens and 9 491 paired peripheral blood specimens were collected from children admitted to Hebei Children′s Hospital for respiratory infection in 2018. RSV-positive sputum specimens were screened by multiple detection reagents for 13 kinds of respiratory pathogens. Flow cytometry was uses to detect T and B lymphocytes and NK cells in peripheral blood samples of randomly screened RSV-positive children. Procalcitonin (PCT) was measured by Roche E411 luminescence analyzer. Hypersensitive C-reactive protein (hs-CRP) was detected by Roche Cobas 8000 C701 biochemical analyzer. White blood cells (WBC) were measured by Sysmex XN-BN3 hematometer.Results:The positive rate of RSV in children with respiratory diseases was 13.08% in Hebei Province in 2018. There were significant differences in RSV-positive rates among different age groups (χ 2=479.297 6, P<0.000 1). The positive rate of RSV decreased gradually with age (χ 2=-20.282 7, P<0.000 1) and was higher in male than in female (χ 2=34.552 7, P<0.000 1). The incidence of co-infection of RSV with other respiratory pathogens was 29.49% (366/1 241), mainly caused by human rhinovirus (HRV, 150/1 241) and adenovirus (ADV, 40/1 241). The main epidemic seasons of RSV infection were winter and spring. The epidemic trends of simple RSV infection and co-infection were consistent. There were significant differences in inflammatory indexes, WBC ( P<0.01), CD4 + ( P=0.015) and CD4 + /CD8 + cells ( P=0.016) between simple RSV infection and co-infection groups. Conclusions:RSV was a common pathogen causing respiratory diseases in children in Hebei Province. The younger the children were, the more likely they were to be infected with RSV. RSV infection was easily complicated by HRV or ADV infection. The epidemic seasons of RSV infection in Hebei were winter and spring. Both simple infection and co-infection of RSV might result in immune dysfunction.

ABSTRACT

To evaluate the effects of resuscitation with normal saline and sodium potassium magnesium calcium and glucose injection on renal structure and function in septic rats. Rat model of sepsis was established by ligation and perforation of cecum. Male SD rats were divided into four groups: sham operation group, sepsis group, saline resuscitation group, sodium potassium magnesium calcium and glucose injection resuscitation group. Blood gas analysis was performed at the end of resuscitation. The rats were sacrificed 72 hours after resuscitation. Blood samples were taken to measure the plasma levels of blood urea nitrogen (BUN), creatinine, interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factorα (TNFα). Caspase-3 expression was detected by immunohistochemistry in kidney sections. The degree of renal injury was evaluated by regular HE staining and electron microscope. Compared with normal saline resuscitation, sodium potassium calcium magnesium glucose injection resuscitation could decrease the levels of BUN, serum creatinine, IL-1β, IL-6 and TNFα ( P<0.05) , reduce the expression of caspase-3 ( P<0.05) , and improve the renal injury score ( P<0.05) . Sodium potassium calcium magnesium glucose injection resuscitation can significantly improve the renal function of sepsis rats with less pathological damage of the kidney.

ABSTRACT

BACKGROUND: Statins plays a significant role in regulating blood lipids, treating and preventing cardiovascular and cerebrovascular diseases. Studies have shown that statins has certain potential in promoting bone formation and treating osteoporosis. OBJECTIVE: To prepare the drug release scaffolds for the sustained release of atorvastatin calcium, which consist of bovine serum albumin microspheres and polycaprolactone electrostatic spinning fibers, and to investigate the effects of the drug sustained release scaffolds on osteoblast adhesion and proliferation. METHODS: Bovine serum albumin microspheres containing atorvastatin calcium were prepared by desolvation. A layer of chitosan was coated on the surface of the bovine serum albumin microspheres by electrostatic adsorption, which can increase the stability of the microspheres. Bovine serum albumin microspheres were purified and lyophilized for later use. The lyophilized powder of microspheres was dissolved in organic solvent. An appropriate amount of hydroxyapatite was added in the solvent. The nanofiber scaffolds for sustained release of atorvastatin calcium were prepared via electrospinning. The micromorphology, degradation performance, and sustained-release performance of the nanofiber scaffolds were characterized. The prepared nanofiber scaffolds for sustained-release of atorvastatin calcium were co-cultured with MC3T3-E1 cells to observe cell adhesion and proliferation. RESULTS AND CONCLUSION: (1) Transmission electron microscopy revealed that the shape of the bovine serum albumin nanospheres was regular and circular. Bovine serum albumin nanospheres were discarded in the electrostatic spinning fibers. The basic morphology of the microspheres was retained. (2) Scanning electron microscopy revealed that the nanofibers used for preparation of nanofiber scaffolds for sustained-release of atorvastatin calcium were composed of filaments with uniform diameters and continuous smooth surface. Filaments were intertwined to form a network structure. (3) The nanofiber scaffolds exhibited the fastest degradation in the first month. The material was incomplete when degraded for 3 months. (4) The nanofiber scaffolds had the ability to slow down the release of drugs. The effect could last for more than 1 month. The overall process of drug release was similar to the zero-order kinetic process. (5) The nanofiber scaffolds for sustained-release of atorvastatin calcium can promote MC3T3-E1 cell adhesion and proliferation. (6) These results suggest that the nanofiber scaffolds for sustained-release of atorvastatin calcium have good biocompatibility and can promote the adhesion and proliferation of osteoblasts.

ABSTRACT

Hypoxic-ischemic encephalopathy (HIE) is the leading cause of neonatal death and neurodevelopmental disorders in infants. Part of patients have different degrees of neurological sequelae, such as cerebral palsy, cognitive and motor function development disorders. Hypoxia-ischemia may activate JAK2/STAT3 signaling pathway, which leads to the microglia activation and neuroinflammation. Down-Regulating JAK2/STAT3 signaling pathway can inhibit microglia activation and regulate the inflammatory injury of nervous system. At present, the treatment of hypoxic ischemic encephalopathy is limited, so the study of regulatory mechanism about microglia activation has important value for the treatment of hypoxic-ischemic encephalopathy. This paper summarizes the role of JAK2/STAT3 signaling pathway in microglia activation and analyzes the relationship between them, in order to provide new ideas and strategies for treatment on hypoxic-ischemic encephalopathy.

ABSTRACT

Objective: To investigate the predictive value of glycated albumin (GA) in renal transplant recipients (RTRs) with post-transplant diabetes mellitus (PTDM). Methods:We conducted a retrospective study. We recruited patients aged ≥18 years old who had no pre-transplant diabetes and received the first renal transplantation (RT) in The First Affiliated Hospital of Xi'an Jiaotong University from January 2017 to December 2017. Patients with pre-transplant thyroid dysfunction, post-transplant impaired fasting glucose, renal graft failure, transplant nephrectomy, loss of follow-up, or death were excluded. According to the diagnostic criteria of PTDM in 2014, on the basis of the results of fasting plasma glucose (FPG) at least twice after 45 days of RT, the patients were divided into post-transplant diabetes mellitus group (PTDM group) and post-transplant normal fasting glucose group (PTNFG group). Each patient was followed up for one year. After comparison of the clinical data of the two groups, SPSS software was used for analyzing the data. Receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of GA for PTDM. Results: In this study, a total of 282 RTR were screened, and 72 patients were not qualified. We recruited 210 patients, with 21 in PTDM group and 189 in PTNFG group. The levels of body mass and body mass index (BMI) in PTDM group were higher than those in PTNFG group (P0.05). GA in PTDM group was higher than that in PTNFG group at 7 days and 14 days after RT (P<0.05). ROC curve analysis showed that the predictive value of GA was the highest at 14 days after RT, its area under ROC curve (AUC) was 0.749. GA was 14.55% at 14 days after RT. Youden index was the largest, with the sensitivity of 57.1% and the specificity of 87.3%. The positive likelihood ratio was 4.5, the negative likelihood ratio was 0.49, the positive predictive value was 57.1%, and the negative predictive value was 87.3%. Conclusion: GA can predict RTR with PTDM at 14 days after RT.

ABSTRACT

Background and Objectives@#Adipose tissue-derived mesenchymal stem cells (ASCs) are recognized as an advantaged source for the prevention and treatment of diverse diseases including type 2 diabetes mellitus (T2DM). However, alterations in characteristics of ASCs from the aforementioned T2DM patients are still obscure, which also hinder the rigorous and systematic illumination of progression and pathogenesis. @*Methods@#and Results: In this study, we originally isolated peripancreatic adipose tissue-derived mesenchymal stem cells from both human type 2 diabetic and non-diabetic donors (T2DM-ASCs, ND-ASCs) with the parental consent, respectively. We noticed that T2DM-ASCs exhibited indistinguishable immunophenotype, cell vitality, chondrogenic differentiation and stemness as ND-ASCs. Simultaneously, there’s merely alterations in migration and immunoregulatory capacities in T2DM-ASCs. However, differing from ND-ASCs, T2DM-ASCs exhibited deficiency in adipogenic and osteogenic differentiation, and in particular, the delayed cell cycle and different cytokine expression spectrum. @*Conclusions@#The conservative alterations of T2DM-ASCs in multifaceted characteristics indicated the possibility of autologous application of ASCs for cell-based T2DM treatment in the future.

ABSTRACT

OBJECTIVE: To investigate the association of UGTs, ABCC2, SLCO1B1 and IMPDH gene polymorphisms with metabolism and adverse reaction of mycophenolate ester in early renal transplant recipients. METHODS: A total of 233 patients who received tacrolimus+glucocorticoid+mycophenolate mofetil treatment after living kidney transplantation were enrolled. Single nucleotide polymorphisms of 13 gene were detected by matrix-assisted laser desorption ionization time-of-flight mass spectrometry. Kruskal-Wallis H test was used to analyze the effect of 13 single nucleotide polymorphisms on the exposure/dose (AUC/D) and adverse reactions of mycophenolic acid in early recipients after renal transplantation. RESULTS: The AUC/D of mycophenolic acid in UGT2B7 802C>T CC and CT genotype recipients was (36.03±16.19) and (38.06±15.41) mg•h•L-1/g•d-1, which was significantly lower than that in TT genotype recipients (43.63±15.10) mg•h•L-1/g•d-1 (P=0.021). The AUC/D of mycophenolic acid in SLCO1B1 521T > C TT, TC and CC genotype recipients were (36.78±15.70), (41.27±12.92) and (45.10±21.32) mg•h•L-1/g•d-1, respectively. There was significant difference between groups (P=0.036). There was no significant difference between 13 single nucleotide polymorphisms and adverse reactions (P>0.05). CONCLUSION: The AUC/D of mycophenolic acid in early recipients after kidney transplantation are associated with the polymorphism of UGT2B7 802C > T and SLCO1B1 521T > C.

ABSTRACT

Objective:To investigate the effect of nurse-led intervention with nutrition and physical exercise combined on body mass index, body composition and incidence of obesity in adults with overweight.Methods:A total of 103 adults with overweight who met enroll criteria and signed informed consent were consecutively enrolled from health examination center, and were randomized into study ( n=51) and control groups( n=52) to receive a 6-month nurse-led intensive nutrition combined physical exercise intervention (study group) or routine nutrition consultation (control group) respectively. Body mass index (BMI), fat-free mass (FFM), body fat rate (BF%), waist-to-hip ratio (WHR), incidence of obesity and abdominal obesity were measured and compared between the two groups pre- and after the intervention. Results:After 6-month intervention, the average energy intake decreased [(92.4±27.2) vs(143.4±23.8)kJ/(kg·d), P=0.035], while the percent of regular physical exercise increased (41.2% vs 19.2%, P=0.015) in study group. Compared to control group, BMI[(22.9±2.1) vs (27.3±2.3)kg/m 2, P=0.045], body fat rate(25.2%±5.5% vs 32.5%±6.3%, P=0.035), WHR(0.88±0.47 vs 0.93±0.58, P=0.040), incidence of obesity (7.8% vs 23.1%, P=0.033) and abdominal obesity (7.8% vs 25.0%, P=0.019) decreased significantly in study group. Conclusion:Nurse-led nutrition combined physical exercise intervention can improve body weight and body composition, as well as decrease the risk of obesity.
