ABSTRACT

Objective: To investigate the prognostic factors of children with congenital heart disease (CHD) who had undergone cardiopulmonary resuscitation (CPR) in pediatric intensive care unit (PICU) in China. Methods: From November 2017 to October 2018, this retrospective multi-center study was conducted in 11 hospitals in China. It contained data from 281 cases who had undergone CPR and all of the subjects were divided into CHD group and non-CHD group. The general condition, duration of CPR, epinephrine doses during resuscitation, recovery of spontaneous circulation (ROSC), discharge survival rate and pediatric cerebral performance category in viable children at discharge were compared. According to whether malignant arrhythmia is the direct cause of cardiopulmonary arrest or not, children in CHD and non-CHD groups were divided into 2 subgroups: arrhythmia and non-arrhythmia, and the ROSC and survival rate to discharge were compared. Data in both groups were analyzed by t-test, chi-square analysis or ANOVA, and logistic regression were used to analyze the prognostic factors for ROSC and survival to discharge after cardiac arrest (CA). Results: The incidence of CA in PICU was 3.2% (372/11 588), and the implementation rate of CPR was 75.5% (281/372). There were 144 males and 137 females with median age of 32.8 (5.6, 42.7) months in all 281 CPA cases who received CPR. CHD group had 56 cases while non-CHD had 225 cases, with the percentage of 19.9% (56/281) and 80.1% (225/281) respectively. The proportion of female in CHD group was 60.7% (34/56) which was higher than that in non-CHD group (45.8%, 103/225) (χ2=4.00, P=0.045). There were no differences in ROSC and rate of survival to discharge between the two groups (P>0.05). The ROSC rate of children with arthythmid in CHD group was 70.0% (28/40), higher than 6/16 for non-arrhythmic children (χ2=5.06, P=0.024). At discharge, the pediatric cerebral performance category scores (1-3 scores) of CHD and non-CHD child were 50.9% (26/51) and 44.9% (92/205) respectively. Logistic regression analysis indicated that the independent prognostic factors of ROSC and survival to discharge in children with CHD were CPR duration (odds ratio (OR)=0.95, 0.97; 95%CI: 0.92~0.97, 0.95~0.99; both P<0.05) and epinephrine dosage (OR=0.87 and 0.79, 95%CI: 0.76-1.00 and 0.69-0.89, respectively; both P<0.05). Conclusions: There is no difference between CHD and non-CHD children in ROSC and survival rate of survival to discharge was low. The epinephrine dosage and the duration of CPR are related to the ROSC and survival to discharge of children with CHD.

ABSTRACT

Objective To Investigate the cause of a food poisoning incident in a city in Dehong Prefecture, determine the scope of the incident, and to formulate effective prevention and control measures. Methods Field epidemiology and case-control study methods were used to formulate case definition; carry out case search; find suspicious food combined with clinical manifestations, dining history and other information; and collect samples from the suspicious food, cases and environment for laboratory testing. Results A total of 160 cases were found and the incidence rate was 26.02% (160/615). The main clinical manifestations were diarrhea, leukocytosis, vomiting, nausea and abdominal pain. The average incubation period was 10.89±5.09 h, with 2 h as the shortest and 28 h as the longest. The epidemiological curve suggested the point source exposure mode. The results of case-control study showed that eating roast pork with green shoots was an independent risk factor (OR=13.09, 95%CI: 3.26‒52.54).16 samples were tested by the local CDC laboratory. Proteus mirabilis was detected in two the anal swabs of two patients He and Chen. Both proteus pani and proteus mirabilis were detected in anal swab of patient Zhou and Proteus pani was detected in roast meat. There was no detection of pathogenic bacteria in other samples. Conclusion Based on the field epidemiological investigation and laboratory test results, we conclude that the food poisoning incident is caused by suspected proteus bacteria. We suggest that the market supervision department should strengthen the supervision of local food hygiene; clarify the sampling rights, responsibilities and technical procedures when medical institutions treat patients with foodborne diseases; ensure finding the causes in time; and take effective prevention and control measures to avoid similar food poisoning events.

ABSTRACT

Objective:To analyze the categories and its relations of recreational physical activities and rehabilitation exercise for adult with disabilities based on the theory and method of International Classification of Functioning, Disability and Health (ICF). Methods:An evidence-based scoping review had been implemented. We had developed the framework and coding approaches for recreational physical activities, rehabilitation exercise and functional improvement for the adults with disabilities based on evidence-based literature review. The literature related to recreational physical activities and rehabilitation exercise of adult with disabilities was searched by subject retrieval method. The retrieval database in Chinese included CNKI and Wanfang database, and the retrieval database in English included PubMed and Web of Science. The retrieval time was from establishment to July 31, 2020. The authors, countries, published time, published journals, research objectives, object of the study and their ages, data collection tool, and the key findings were extracted. Results:A total of 2476 literatures were returned, and 18 of them were enrolled, which were published in 14 countries, and most were published in journals on topics related to medicine, public health, exercise and people with disabilities. They were mainly published from 2010 to 2020, and mainly used questionnaire survey, measurement and interviewing method. There were three typical recreational physical activities: physical fitness activities, skills activities and sports activities, mainly including Taiji Quan, wheelchair basketball, leisure outdoor activities, community recreational sports activities and rehabilitation exercises, etc. According to the framework of ICF, recreational physical activities promote functional rehabilitation for adults with disabilities, including physical functions (b1 mental function; b4 cardiovascular, blood, the function of the immune system and respiratory system; b5 digestion, metabolism and function of the endocrine system; and b7 nerve musculoskeletal function related to movement), and activities and participation (d1 study and application of knowledge; d2 the general tasks and requirements; d4 activity; d5 self-care; d7 interpersonal communication and interpersonal relationship; and d9 community, social and civic life). The evidences showed benefits of improvement in the fields of body mass index, body index, athletic ability, balance ability, and cognitive function. There were more gains at individual levels, including support, coping with stress, self-concept development, life satisfaction, happiness, exercise self-efficacy, health perception, etc. The environmental and personal factors had effects on the performance of activity and participation in recreational physical activities, including e1 products and technologies, e4 attitude, e3 support and interpersonal relationships, e5 service system and policy, as well as attitudes and support of family members and colleagues, interpersonal relationships, social support, transportation, equipment and facilities, and policies. Conclusion:Rehabilitation exercise is an important part of health-related services. We scoped the recreational physical activities and its functional effects for adults with disabilities. The categories and structure of recreational physical activities and rehabilitation exercises were constructed based on ICF. Aligning rehabilitation exercises and relevant factors to ICF, the recreational activities and rehabilitation exercises had been reviewed and discussed and several recommendations for further studies had been drawn.

ABSTRACT

BACKGROUND: Mesenchymal stem cells have been widely applied in autoimmune diseases and graft-versus-host diseases because of their immunomodulatory capabilities. However, mesenchymal stem cells have plasticity in immunomodulation, which leads to heterogeneity and instability when used in vivo. OBJECTIVE: To investigate the polarization of human umbilical cord derived mesenchymal stem cells to an immunosuppressive phenotype (MSC2) in the inflammatory microenvironment induced by interferon-γ and lipopolysaccharide. METHODS: Human umbilical cord-derived mesenchymal stem cells were isolated and cultured in vitro, and then were identified by morphological characteristics, surface markers, adipogenesis and osteoinduction activity. Human umbilical cord-derived mesenchymal stem cells were treated with interferon-γ (10 μg/L), lipopolysaccharide (100 μg/L), or their combination for 24 hours, respectively, and were then co-cultured with phytohemagglutinin pre-treated peripheral blood mononuclear cells for 5 days under direct or Transwell indirect contact. The percentages of regulatory T cells and T helper 1 cells were analyzed by flow cytometry at different times. The mRNA expression levels of Toll-like receptors 2, 3 and 4 were detected by real-time fluorescence quantitative PCR. RESULTS AND CONCLUSION: (1) Human umbilical cord derived mesenchymal stem cells exhibited spindle-shaped or fibroblast-like morphology, highly expressed CD73, CD90 and CD105, and lacked expression of CD34, CD45 and HLA-DR. (2) Under direct or indirect co-culture, human umbilical cord-derived mesenchymal stem cells pre-treated with interferon-γ and lipopolysaccharide could promote the generation of regulatory T cells, which was superior to the interferon-γ, lipopolysaccharid, un-treated and control groups (P < 0.05). (3) The percentage of T helper 1 cells gradually decreased over time. (4) Under indirect co-culture, human umbilical cord derived mesenchymal stem cells pre-treated with interferon-γ and lipopolysaccharide were polarized into immunosuppressive MSC2 phenotype at an earlier period and highly expressed Toll-like receptor 3 (P < 0.05). (5) In conclusion, the combination of interferon-γ (10 μg/L) and lipopolysaccharide (100 μg/L) results in the high-efficient polarization of mesenchymal stem cells toward the MSC2 phenotype under indirect co-culture, and the immunosuppressive capability of MSC2 is independent of intercellular contact, which provides clinical evidence for the MSC2-derived exosome therapy in the future.

ABSTRACT

@#This study aimed to investigate the clinical efficacy of pulsed radiofrequency (PRF) of the dorsal root ganglion (DRG) with pain management as treatment of post-herpetic neuralgia (PHN). A total of 78 patients with PHN in the thoracolumbar region were randomly divided into two groups (n = 39 for each group): Group A, oral drug treatment only; Group B, DRG PRF of the thoracic spinal nerve combined with oral drug treatment. The numerical rating scale (NRS) scores of both groups were observed before treatment and at 1, 4, 8, and 12 weeks after treatment. The results showed that the NRS scores of both groups were significantly decreased after treatment (P < 0.05). In addition, the NRS score in Group B decreased significantly more than in Group A (P < 0.05). In conclusion, DRG PRF with pain management is a safe and effective treatment for elderly PHN patients, and it can quickly alleviate pain symptoms.

ABSTRACT

@#Objective To analyze the epidemic situation and characteristics of spatial autocorrelation and spatiotemporal regular of hand,foot and mouth disease( HFMD) in Yunnan Province during the period from 2014 to 2018,thus to provide theoretical basis for HFMD prevention and control. Methods Descriptive epidemiologic method was used to analyze the epidemic situation of HFMD,spatial autocorrela- tion was used to analyze the spatial cluster aggregation,and discrete Possion model in spatio-temporal in scan was used to detect HFMD's spatio-temporal clustering condition. Results The incidence of HFMD in Yunnan Province had been risen rapidly during the past 5 years. Cases mainly occurred among the group of male,0-4 years old group and scattered children. The predominant pathogen had changed,Other enterovir- us gradually replaced enterovirus 71( EV71) to be the predominant. HFMD cases and pathogen showed sig- nificant spatial clustering aggregation,HFMD cases hot spots mainly concentrated in the central and south- central part of Yunnan Province. The amount of EV71 cases hot spots increased gradually,and the hot spot areas augmented and extended to the central and south-central part of Yunnan Province. There was obvious spatial-temporal aggregation of HFMD,annual scan results detected 3 first-level cluster areas and 1 second -level cluster area. Clustering time was mainly concentrated in April to October of each year. Conclusions Distribution characteristics of HFMD among people in Yunnan Province did not change significantly during the period from 2014 to 2018,while the proportion of pathogenic spectrum changed significantly. The key areas of HFMD control and prevention were still in the central and central-south part of Yunnan Province,while the aggregation and break of HFMD in these areas from April to October should be concerned.

ABSTRACT

Objective@#To investigate the effects of artesunate treatment on chronic graft-versus-host disease (cGVHD).@*Methods@#Recipient BALB/c mice received 8 × 106 bone marrow cells with 8×106 spleen cells from B10D2 mice. Artesunate solubilized in acetone was injected intraperitoneally every day at the dose of 1 mg/kg at Day 28 after BMT. The clinical scores, survival and histopathological damage were analyzed. The frequency of Th17 and Tregs in PB and spleens from the mice were evaluated by flow cytometry. In addition, CD4+ T cells from the spleens of mice were cultured in vitro, then stimulated with artesunate, the frequency of Th17 and Tregs in these splenocytes were evaluated by flow cytometry.@*Results@#Artesunate administration diminished clinical and histopathological damage, and improved the survival of cGVHD mice[(46.57±7.83)% vs (55.71±6.99)%, χ2=5.457, P=0.020]; Artesunate contributed to Tregs development [(4.45±0.04)% vs (8.40±0.23)%, t=15.679, P<0.001; (6.62±0.24)% vs (10.48±0.48)%, t=6.587, P=0.003] while decreased Th17 cells [(1.51±0.18)% vs (0.58±0.19)%, t=7.233, P<0.001; (1.48±0.38)% vs (0.71±0.18)%, t=3.653, P=0.011] expressions in both PB and spleens, and decreased the Th17/Treg ratio (0.34±0.05 vs 0.09±0.03, t=7.621, P=0.002; 0.19±0.03 vs 0.06±0.02, t=6.993, P=0.002). Moreover, artesunate suppressed the Th17 cells expressions [(0.82±0.37) % vs (3.39±1.22) %, t=4.044, P=0.007] and contributed to Tregs development [(34.63±1.29) % vs (14.28±1.69) %, t=19.119, P<0.001], and also decreased the Th17/Treg ratio (0.24±0.09 vs 0.02±0.01, t=4.780, P=0.003) in vitro.@*Conclusions@#Artesunate suppressed the Th17 cells expressions and contributed to Tregs development, which provided new sights into the development of a novel drug for cGVHD, e.g., artemisinin.

ABSTRACT

OBJECTIVE@#To investigate the effects of exosomes from human umbilical cord mesenchymal stem cells on the development of Treg and TH17 cells.@*METHODS@#Exosomes from the serum-free-culture supernatants of hUC-MSC were harvested by ultracentrifugation. The electron microscopy, nanoparticle tracking analysis and western blot were used to identify the hUC-MSC-exosomes, such as the morphology, the paticle chameter, and the protein content. The PBMC stimulated with anti-CD3/CD28 were incubated with the exosomes for five days, and then the percentage changes of Treg and TH17 cells were analyzed by using flow cytometry.@*RESULTS@#The hUC MSC-derived exosomes were saucer-like in morphology the averge diameter was approximately 142 nm. They were identified as positive for CD9 and CD63. Flow cytometry showed that the proportion of CD4CD25Foxp3 Treg cells in the PBMC were significantly higher, but the proportion of CD4IL17A T cells in the hUC-MSC-exosome group was obviously lower than that in the group without the hUC-MSC-exosom (control group) (P<0.05).@*CONCLUSION@#The hUC-MSC-exosomes have an immunomodulatory effect on T cells in vitro by increasing the ratio of Treg and reducing the ratio of TH17 cells, expecting the hUC-MSC-exosom as a novel cell-free target for immunotherapy.

ABSTRACT

Objective@#To understand the epidemiological characteristics of imported acute infectious diseases between 2008 and 2017 in the border areas of Yunnan province.@*Methods@#All the cases occurred between January 2008 and December 2017 and related information was from the Chinese CDC infectious disease report information management system, according to definition of imported cases diagnosed by clinicians. Epidemiological characteristics of the imported cases of related information were gathered.@*Results@#A total of 13 157 imported acute infectious diseases were reported from the border areas of Yunnan province, which accounted for 6.03% (13 157/218 284) of the total number of acute infectious diseases in the same areas from 2008 to 2017. Malaria, dengue fever and hand-foot-mouth disease were accounted for 56.05% (7 374/13 157), 21.82% (2 871/13 157) and 4.62% (608/13 157), of all the case, respectively. The number of imported malaria cases decreased annually. However, dengue fever showed a sharp increase. Peaks of the epidemics appeared as: May for malaria and October for dengue fever. Male patients were accounting for the majority (73.22%, 9 634/13 157), so as the patients with Chinese nationality (54.91%, 7 225/13 157). The age distribution appeared as: 67.12% (8 829/13 157) for the 15-44 year olds and 19.26% (2 535/13 157) were children below 14 years of age. Proportions of occupation appeared as: farmers (45.23%, 5 596/13 157), migrant workers (21.30%, 2 802/13 157) and children living at home (11.12%, 1 463/13 157). Most of the imported cases were coming from Myanmar and appearing in the following three counties: Ruili city, Tengchong city, and Yingjiang of Yunnan province. Cities/counties that with number of imported cases more than 10% of the local reported cases, would include Ruili city, Tengchong city, Zhenkang county and Mangshi of Yunnan province.@*Conclusions@#Imported acute infectious disease was a serious public health problem in Yunnan province, 2008-2017. The main imported acute infectious diseases were malaria, dengue fever and hand-foot-mouth disease. The majority imported cases were accounting for Chinese, male, young adults and farmers. It is also important for immigration workers to carry out surveillance, prevention and control programs on infectious diseases when working in neighboring countries.

METHODS:A total of 68 PAD patients in our hospital from Jan. 2015 to Jan. 2016 were di-vided into observation group(34 cases)and control group(34 cases)according to random number table. Control group was given basical treatment,and Alprostadil injection 2 mL+0.9% Sodium chloride injection 100 mL,ivgtt,qd. Observation group was addi-tionally given Cilostazol tablets 100 mg,po,bid,on the basis of control group. Both groups were treated for 30 days. Clinical effi-cacies of 2 groups were observed. The hemorheology indexes(hematocrit,whole blood high-shearing viscosity,erythrocyte aggre-gation index,erythrocyte deformation index,plasma viscosity),inflammatory factor indexes(TNF-α,IL-6,IL-8, hs-CRP),oxida-tion stress indexes(GSH-Px,SOD,T-Aoc,MDA),arteriosclerosis indexes(ABI,TBI,dorsalis pedis artery blood flow)were de-termined before and after treatment. The occurrence of ADR was recorded. RESULTS:Total response rate of observation group (91.18%)was significantly higher than that of control group(79.41%),with statistical significance(P0.05). After treatment,hematocrit,whole blood high-shearing viscosity,erythrocyte aggregation index,erythrocyte deformation index,plasma viscosity,the levels of TNF-α,IL-6,IL-8,hs-CRP and MDA in 2 groups were de-creased significantly;while the levels of GSH-Px,SOD,T-Aoc,ABI,TBI and dorsalis pedis artery blood flow were increased sig-nificantly;the improvement of above indexes in observation group was significantly better than control group,with statistical signif-icance(P0.05). CONCLUSIONS:For PAD,cilostazol combined with alprostadil can effectively improve hemorheolo-gy indexes,inflammatory factor indexes,oxidation stress indexes and arteriosclerosis indexes with good safety.

ABSTRACT

AIM: To investigate the effect of epidermal growth factor receptor (EGFR) inhibitor erlotinib on kidney injury in diabetic nephropathy (DN) rat and the underlying mechanism.METHODS: The rat model of DN was induced by intraperitoneal injection of streptozotocin (STZ) at dose of 55 mg/kg.One week after STZ injection, the rats with blood glucose level exceeding 16.7 mmol/L were identified as diabetic.Diabetic rats were randomly divided into 2 groups: STZ group and STZ+erlotinib group.In addition, the normal rats were used as control group.The rats in STZ+erlotinib group were treated with erlotinib at 100 mg·kg-1·d-1 for 4 weeks(5th~8th week).The fasting blood glucose (FBG), serum creatinine (SCr) and 24 h urine protein were measured.The pathological changes of the kidney were observed by HE staining and Masson staining.The protein levels of EGFR, p-EGFR, transforming growth factor β1 (TGFβ1), Smad2/3, p-Smad2/3, collagen Ⅳ (ColⅣ) and fibronectin in the kidney tissues were determined by Western blot.The reactive oxygen species (ROS) level and malondialdehyde (MDA) content in the renal tissues were futher analyzed.RESULTS: Compared with control group, the levels of FBG, 24 h urine protein and Scr were significantly increased in STZ group (P<0.01).Compared with STZ group, the levels of FBG, 24 h urine protein and SCr in STZ+erlotinib group were markedly decreased (P<0.05).In additon, the glomerular structure was restored to normal, the proliferative degree of mesangial cells markedly attenuated, and the epithelial cells were in alignment in STZ+erlotinib group.Moreover, erlotinib significantly inhibited the protein levels of p-EGFR, TGFβ1, p-Smad2/3, ColⅣ and fibronectin in the kidney tissues of STZ rats.In addition, erlotinib also significantly inhibited the levels of ROS and MDA in the kidney tissues of STZ rats.CONCLUSION: Erlotinib ameliorates STZ-induced diabetic nephropathy possibly through inhibiting the activation of EGFR/TGFβ1-Smad2/3 signaling pathway in association with suppression of fibrosis and oxidative stress.

ABSTRACT

The Cashmere goat is mainly used to produce cashmere, which is very popular for its delicate fiber, luscious softness and natural excellent warm property. Keratin associated protein (KAP) and bone morphogenetic protein (BMP) of the Cashmere goat play an important role in the proliferation and development of cashmere fiber follicle cells. Bacterial artificial chromosome containing kap6.3, kap8.1 and bmp4 genes were used to increase the production and quality of Cashmere. First, we constructed bacterial artificial chromosomes by homology recombination. Then Tol2 transposon was inserted into bacterial artificial chromosomes that were then transfected into Cashmere goat fibroblasts by Amaxa Nucleofector technology according to the manufacture's instructions. We successfully constructed the BAC-Tol2 vectors containing target genes. Each vector contained egfp report gene with UBC promoter, Neomycin resistant gene for cell screening and two loxp elements for resistance removing after transfected into cells. The bacterial artificial chromosome-Tol2 vectors showed a high efficiency of transfection that can reach 1% to 6% with a highest efficiency of 10%. We also obtained Cashmere goat fibroblasts integrated exogenous genes (kap6.3, kap8.1 and bmp4) preparing for the clone of Cashmere goat in the future. Our research demonstrates that the insertion of Tol2 transposons into bacterial artificial chromosomes improves the transfection efficiency and accuracy of bacterial artificial chromosome error-free recombination.

ABSTRACT

BACKGROUND:The chemical compositions and structure of calcium phosphate bone cement are similar to those of human bone, which can fil the bone colapse caused by fracture and induce osteogenesis, but its degradation rate is slow. OBJECTIVE:To evaluate the biocompatibility of the calcium phosphate cement/fibrin glue and the feasibility of repairing radius defects. METHODS: In vitro cytotoxicity experiment: Mouse fibroblasts were cultured in the calcium phosphate bone cement/fibrin glue extracts, phenol solution, and RPMI 1640 culture medium containing 10% fetal bovine serum, respectively, to detect the cytotoxicity grade. Hemocompatibility experiment: Calcium phosphate bone cement/fibrin glue extracts, normal saline and distiled water were respectively added into the rabbit anticoagulation, to detect the hemolytic rate. Forty-five New Zealand white rabbits were enroled and modeled into bilateral radius defects, folowed by randomly alotted into three groups: blank control group without any intervention, experimental and control groups were given the implantation with calcium phosphate bone cement/fibrin glue and autologous radius, respectively. X-ray, histology, bone mineral density and biomechanical test were performed at postoperative 4, 8 and 16 weeks. RESULTS AND CONCLUSION:The toxicity grade of the calcium phosphate cement/fibrin glue was 0 to 1. The hemolytic rate of the calcium phosphate cement/fibrin glue was 3.15%. At 16 weeks postoperatively, X-ray showed that in the experimental and control groups, the fracture line disappeared completely, pulp cavity was recanalized, and in plastic completely. Histology showed that the reconstructed bone trabecular was obvious, plate layer of bone was mature, and medulary cavity recanalization appeared in the control group; there were a large number of new grid-shaped woven bone tissues growing into the material in the experimental group, with overt degradation, and degradation rate was in paralel to bone ingrowth. The bone density, the maximum load, maximum stress and failure energy in the experimental and control groups were significantly higher than those in the blank control group (P < 0.05), and al above indicators showed no significant differences between the experimental and control groups. These results manifest that the calcium phosphate bone cement/fiber protein glue composite material holding a good biocompatibility can promote bone tissue regeneration for bone defect repair, achieving similar curative effect with autologous bone transplantation.

ABSTRACT

Objective To observe the expression of Klotho and Na+/Pi cotransporter in high phosphorous-induced rats with 5/6 nephrectomy and its relationship with vascular calcification,as well as to investigate the effect of early intervention by sodium thiosulfate (STS) on the progression of vascular calcification.Methods Either 5/6 nephrectomy (n=21) or sham operation (n=14) was conducted on 35 Sprague Dawley rats,who were then fed with high phosphorus (HP) diet or normal phosphorus (NP) diet for 16 weeks respectively.The rats were divided into 5 groups as follows:(1) remnant kidney rats receiving HP diet (NHP,n=7),(2) remnant kidney rats receiving NP diet (NNP,n=7),(3) sham operation rats receiving NP diet (SNP,n=7),(4) sham operation rats receiving HP diet (SHP,n=7),(5) remnant kidney rats receiving HP diet with STS (THP,n=7).The treatment group was given STS intraperitoneally three times a week for 16 weeks.At the end of the 16th week,rats tail artery blood pressures were tested,serum creatinine (Scr),calcium (Ca2+),phosphorus (P3+),FGF23,iPTH and urine protein were examined.Throacic aorta and kidney were then removed.Vascular calcification was confirmed by Von kossa staining.Klotho and Pit-1 expression in aortas were determined by immunohistochemistry.Renal lesion was determined by PASM-Masson staining.Renal Klotho and NaPi-2a mRNA were determined by real time RT-PCR.Results After 16 weeks,Scr,p3+,FGF23,iPTH,uric protein and blood pressure were significantly higher in NHP than those in SNP rats (all P < 0.05).PASM-Masson staining revealed typical renal pathology of chronic renal failure in NHP group.With the treatment of STS,THP rats showed significant decrease in Scr,t3+,FGF23,iPTH,uric protein and blood pressure by comparison with NHP group (all P < 0.05).Significant vascular calcification was found in NHP group while NNP and SHP group occasionally had vascular calcification;THP group had marked alleviation of vascular calcification.The aorta and renal expression of Klotho decreased remarkably while expression of Pit-1 and NaPi-2a increased significantly in NHP compared with SNP group (all P < 0.05).Accordingly,the aorta and renal expression of Klotho increased and Pit-1 and NaPi-2a decreased significantly in THP compared with NHP group (P < 0.05).Conclusions The early intervention of sodium thiosulfate might regulate Klotho and Na +/Pi cotransporter expression in both aorth and kidney,decreasing serum phosphate,delaying progression of vascular calcification and improving renal function.
