OBJECTIVE: To explore the effect of cadmium on bone formation and its mechanism in male mice. METHODS: i) The specific pathogen-free C57 BL/6 J wild-type male mice were divided into control group and cadmium exposure group, with 10 mice in each group. Mice in the cadmium exposure group were intraperitoneally injected with 2 mg/kg body weight cadmium chloride twice a week for eight weeks, and mice in the control group were intraperitoneally injected with the same amount of 0.9% sodium chloride solution. After that, the bone mineral density and bone microstructure of the femur of mice were detected by a high-resolution microcomputed tomography scanner. ii) Human SV40-transfected osteoblast cells(hFOB1.19) were divided into control group and cadmium exposure group. The cadmium exposure group was treated with 0.5 μmol/L cadmium chloride solution, cells in the control group were given an equal volume of α-low-limit minimal medium. After culture, the differentiation and mineralization ability of hFOB1.19 cells were analyzed by alkaline phosphatase(ALP) and alizarin red staining, respectively. Cell viability was examined by CCK-8 assay. The protein expression of Janus kinase 2(JAK2), total signal of transducers and activator of transcription 3(tSTAT3) and phosphorylated signal transducers and activator of transcription 3(pSTAT3) was detected by Western blotting. The expression of osteoblastic marker genes ALP, Runt-related transcription factor 2(RUNX2) and osteocalcin(OCN) was detected by real-time quantitative polymerase chain reaction.RESULTS: Compared with the control group, the average bone mineral density decreased(P<0.01), bone volume fraction decreased(P<0.05), the bone trabecula thickness became thinner(P<0.01), the number of bone trabecula decreased(P<0.05), trabecular bone spacing increased(P<0.05) in the femur of mice in cadmium exposure group. The viability of hFOB1.19 cells was decreased [(100.0±10.8)% vs(49.1±8.2)%, P<0.01]. The differentiation ability of osteoblasts was reduced and the mineralization was inhibited. The relative expression levels of JAK2 and pSTAT3 in cells decreased(all P<0.05) and the relative expression levels of osteoblast marker genes ALP, RUNX2 and OCN decreased(all P<0.01).CONCLUSION: Cadmium can induce mice bone loss, which may be due to its inhibition of osteoblastic function by reducing the expression of JAK2 and STAT3 proteins.

BACKGROUND: Stem cells intra-articular injection stagey indicated a potential therapeutic effect on improving the pathological progress of osteoarthritis (OA). However, the long-term effect of stem cells intra-articular injection on the cartilage regeneration remains unclear. miR-29a-3p is predicted to be a critical target for inhibiting insulin-like growth factor-1 expression and may aggravate the progression of OA. METHODS: In this study, we investigated the therapeutic efficacy of intra-articular injection of bone marrow mesenchymal stem cells (BMSCs) transfected with miR-29a-3p inhibitor in OA. RESULTS: miR-29a-3p inhibitor transfection did not influence cell viability of BMSCs, while the chondrogenic differentiation potential of BMSCs was significantly improved. Interestingly, intra-articular injection of BMSCs with miR-29a-3p inhibition significantly prevented articular cartilage degeneration by up-regulating the expression of Sox 9, Col-2a1, aggrecan and down-regulating the expression of matrix metalloproteinase, as well as relieved pain in OA. CONCLUSION The double effects on cartilage protection and pain relief indicated a great potential of intra-articular injection of miR-29a-3p inhibitor-transfected BMSCs for the treatment of OA.

【Objective】 To investigate the willingness of whole blood donors to donate apheresis platelets and analyze its influencing factors. 【Methods】 A total of 400 whole blood donors from Kunshan Blood Station and Leshan Blood Station from January to May, 2023 were surveyed by random sampling, and their willingness to donate apheresis platelets were analyzed by univariate analysis and binary logistic regression analysis. 【Results】 A total of 386 valid questionnaires were collected, with a recovery rate of 96.5%. Among the 386 whole blood donors, 177 were willing to donate apheresis platelets, accounting for 45.9%.

BACKGROUNDMost of the studies on traditional Chinese medicine (TCM) 'spleen' deficiency syndrome in the recent 30 years were conducted only on the basis of single functional index, neglecting the study on the pathophysiologic internal relationship between spleen deficiency syndrome and gastric diseases in modern medicine. But it was at the subcellular molecular biological level that we explored the pathophysiologic basis of classification of spleen deficiency in chronic gastritis by detecting the bioactive substances in gastric mucosa nuclei and mitochondria.

METHODSBy means of optical microscope, scanning electron microscope (SEM), transmission electron microscopy (TEM) and histochemical staining, we conducted histopathological, subcellular ultrastructural analysis and nuclei and mitochondrial ultrastructural analysis of gastric mucosa of 188 spleen deficiency patients and of 42 voluntary blood donors. At the same time, bioactive substances were measured by means of X-ray energy dispersive analysis system (EDAX) image analysis system, radioimmunoassay method and chemiluminescence method.

RESULTSThe content of cAMP, superoxide dismutase (SOD), Zn and Cu in gastric mucosa, and the content of Zn and Cu in mitochondria decreased progressively in order of groups: healthy control (HC), spleen Qi deficiency without organic lesion (F-SQD), spleen Yang deficiency without organic lesion (F-SyangD), disease without symptoms group, spleen Qi deficiency with organic lesion (G-SQD), spleen Yang deficiency with organic lesion (G-SyangD), spleen Yin deficiency (SyinD) and spleen deficiency with Qi stagnation (SDQS), chronic spleen deficiency gastritis (CSG) and chronic atrophic gastritis (CAG); decreased in order of HC, intestinal metaplasia (IM)Ia, IMIb, IMIIa and IMIIb, P < 0.05. The content of DNA, Zn and Cu in nuclei progressively increased in order mentioned above, P < 0.05.

CONCLUSIONSThe quantitative changes of gastric mucosal cAMP, SOD, Zn, Cu, of mitochondrial Zn, Cu and of nuclear DNA, Zn and Cu are not only the substance base on which the lesion of gastric mucosa tissue structure occurs, but also the substance base on which spleen deficiency is classified. G-SQD and G-SyangD were more likely to be found in low-grade or middle-grade CSG and CAG, while SyinD and SDQS in middle-grade or high-grade CSG, CAG and IMIIb.

Objective: To investigate current status and associated factors of preschool children’s physical fitness, in order to provide scientific basis for improving preschool children’s physical fitness. Methods: A total of 3 240 preschool children aged 3-6 years old in Kunshan city were selected through cluster sampling method. They were surveyed about physical fitness and influencing factors. Results: The number of excellence of preschool children’s physical fitness was 269, and the rate was 8.30 percent. The excellence rates of preschool children’s physical fitness in girls, high grade, non-residency in Jiangsu Province were higher(10.87%, 10.96%, 14.88%), and the excellence rate of preschool children’s physical fitness in premature group was lower(4.31%)(P<0.05). Further unconditioned logistic regression analysis found that girls, middle and high grade and non-residency in Jiangsu Province were the protective factors for the excellence of preschool children’s physical fitness, OR values were 1.96, 1.94, 2.45 and 1.87, respectively; premature was a risk factor for the excellence of preschool children’s physical fitness, OR value was 0.47. Conclusion Preschool children in Kunshan have poor physical fitness, especially in boys, low grade and premature groups. Education department and health department should work together to improve the preschool children’s physical fitness.

ObjectiveTo evaluate and compare the curative effect and the safety of sclerotherapy of venous malformation in children using absolute ethanol and pingyangmycin.MethodsEighty children with venous malformation were treated by sclerotherapy with absolute ethanol or pingyangmycin under general anesthesia during February of 2009 to May of 2011. Diagnostic criteria included the presence of a bluecolored lesion at birth,with gradual increase in its size associated with a positive postural test.MRI showed characteristic imaging features.Eighty patients were divided into two groups by randomization.Forty patients were treated with absolute ethanol,and the remaining 40 patients with pingyangmycin. The therapeutic effects and side effects were observed and recorded during a follow-up period of 6 to 24 months ( average 15 months).Treatment results weredividedinto four categories: cure, basiccure, effective, and ineffective,and the former three categories were considered effective in treatment.Chi-square test was used to compare the rate of effective treatment and rate of complications in these two groups.ResultsThe effective patients treated with absolute ethanol was 38 (95.0％,38/40),and the effective patients with pingyangmycin was 26(65.0％,26/40),x2 test ( x2 =11.25,P ＜ 0.01 ) difference was statistically significant.Eight patients developed skin necrosis; 4 patients serious local swelling,2 patients muscle fibrosis,1 patient cerebral embolism in the absolute alcohol group.Two patients developed postoperative fever and vomiting and 2 skin necrosis in the pingyangmycin group,the difference was statistically significant (x2 =12.29,P ＜0.01 ). ConclusionsSclerotherapyiseffectiveforthetreatmentofvenousmalformationsin children.Absolute ethanol is more effective,but associated with more complications,such as skin necrosis or as serious as cerebral embolism,than pingyangmycin.

Objective To explore the effect and safty of interventional embolization of congenital arteriovenous fistula (CAVF) in the common femoral profounda artery in children.Methods Eight children (aged 6 to 14 years ;6 males and 2 females) with CAVF underwent interventional embolization From January 2006 and December 2010.Color Doppler sonography and DSA were performed on all patients.Arterial duplex imaging revealed the arteriovenous fistula in the common femoral profounda artery and DSA further confirmed the presence of an AVF over the common femoral profounda artery via the other vein.All children were treated with interventional embolization therapy by the injection ofcoils or ethanol through a microcather.It was necessary to performed repeated interventional embolization if the lesion was not obliterated in 4 weeks.All patients were followed-up from 6 months to 2 years and the clinical symptoms were observed.Results Arteriograpy can clearly demonstrate the femoral profounda artery and its branches as well as the fistula.Ten interventional embolization procedures were performed.Forty seven coils were deployedduring the procedure and seven ethanol embolization procedures were performed.Post-procedural angiography revealed complete occlusion in 8 patients.No major complications such as ectopic coil embolization,tissue necrosis,peripheral nerve palsy or cardio-pulmonary collapse were found.The abnormal AVFs were embolized completely in 7 cases after only one therapy and there was no recurrent disease in the 6 months to 2 years follow-up.Some tiny AVFs were still found in another case which underwent three additional treatments.However,the clinical symptoms were under control.Conclusion Interventional embolization is a safe and effective therapeutic method for CAVF of the common femoral profounda artery in children and it might become the primary treatment option.
