ABSTRACT

OBJECTIVE@#To explore if acupoint injection can improve analgesic effects or delivery outcomes in parturients who received combined spinal-epidural analgesia (CSEA) and patient-controlled epidural analgesia (PCEA) for labor analgesia.@*METHODS@#A total of 307 participants were prospectively collected from July 2017 to December 2019. The participants were randomized into the combined acupoint injection with CSEA plus PCEA group (AICP group, n=168) and CSEA plus PCEA group (CP group, n=139) for labor analgesia using a random number table. Both groups received CSEA plus PCEA at cervical dilation 3 cm during labor process, and parturients of the AICP group were implemented acupoint injection for which bilateral acupoint of Zusanli (ST 36) and Sanyinjiao (SP 6) were selected in addition. The primary outcome was Visual Analogue Scale (VAS) score, and the secondary outcomes were obstetric outcomes and requirement of anesthetics doses. Safety evaluations were performed after intervention.@*RESULTS@#The VAS scores were significantly lower in the AICP group than in the CP group at 10, 30, 60, and 120 min after labor analgesia (all P<0.05). The latent phase of the AICP group was shorter than that of the CP group (P<0.05). There were less additional anesthetics consumption, lower incidences of uterine atony, fever, pruritus and urinary retention in the AICP group than those in the CP group (all P<0.05).@*CONCLUSION@#Acupoint injection combined CSEA plus PCEA for labor analgesia can decrease the anesthetic consumption, improve analgesic quality, and reduce adverse reactions in the parturients.

ABSTRACT

@#AIM: To investigate the difference of the optic vessel density in early primary open angle glaucoma(POAG), ocular high tension subjects and healthy subjects. <p>METHODS: A cross-sectional study. From January 2019 to April 2021, patients were selected in the Department of Glaucoma in Fuzhou Southeast Eye Hospital. There were 45 patients(70 eyes)of early POAG group, including 32 males(49 eyes)and 13 females(21 eyes)with age of 48.50(26.75, 64.50)years. There were 37 patients(65 eyes)of ocular high tension group, including 17 males(29 eyes)and 20 females(36 eyes)with age of 37.00(27.00, 47.00)years. There were 51 patients(94 eyes)of healthy group, including 23 males(39 eyes)and 28 females(55 eyes)with age of 46.00(34.50, 56.50)years. Ophthalmic examinations including best-corrected visual acuity(BCVA), intraocular pressure, central corneal thickness(CCT), mean deviations(MD), retinal nerve fiber layers thickness(RNFL)were measured in three groups. The center area, the inner circle area, the outer circle area, and the whole area of the optic vessel density in three groups were measured <i>via</i> optical coherence tomography angiography(OCTA)device.<p>RESULTS: The difference of the intraocular pressure in early POAG group-ocular high tension group was not significant(<i>H</i>=146.876,<i>P</i><0.001), while significantly in early POAG group-healthy group and ocular high tension group-healthy group(all <i>P</i><0.01). Significant differences in BCVA, MD, and RNFL were observed in early POAG group-ocular high tension group(<i>P</i>=0.005, <i>P</i>=0.01, <i>P</i><0.01)and early POAG group-healthy group(<i>P</i>=0.013, <i>P</i><0.01, <i>P</i><0.01), while the difference was not found in ocular high tension group-healthy group(<i>P</i>=1.000, <i>P</i>=0.660, <i>P</i>=1.000). There was no difference of CCT in early POAG group-healthy group(<i>P</i>=0.074), and significant differences were observed in early POAG group-ocular high tension group and ocular high tension group-healthy group(<i>P</i>=0.006, <i>P</i><0.01). The optic vessel density comparison in the center area, the inner circle area, and the whole area were significantly different in early POAG group-ocular high tension group(all <i>P</i><0.01)and in early POAG group-healthy group(all <i>P</i><0.01), which indicated that the optic vessel density was obviously less in the early POAG group than the other two groups. The optic vessel density had no significant difference in ocular high tension group-healthy group in these areas(all <i>P</i>=1.000). In the outer circle area, there were no significant differences of the optic vessel density in early POAG group-ocular high tension group and early POAG group-healthy group(<i>P</i>=0.067, <i>P</i>=0.877), while significant difference was observed in early POAG group-healthy group(<i>P</i>=0.001).<p>CONCLUSION: The optic vessel density was decreased in early POAG comparing with ocular high tension subjects and healthy subjects, which was agree with the changes of MD, RNFL. The optic vessel density decreased firstly from the center area and the inner circle area for early POAG.

ABSTRACT

Objective:To explore the clinical features and treatment strategies of the transsyndesmotic ankle fracture dislocation.Methods:Data of 26 patients of transsyndesmotic ankle fracture dislocation who were treated in our hospital from December 2013 to November 2020 were retrospectively analyzed. There were 16 men and 10 women with an average age of 49.54±12.81 years (range, 26-68 years). Open injuries in 17 cases, of which the Gustilo-Anderson II type in 6 cases, IIIA type in 11 cases, closed injuries in 9 cases. According to the AO/OTA fracture classification, 44B type in 4 cases, 44C type in 22 cases. According to the Lauge-Hansen classification, there were 16 cases of pronation-abduction, 10 cases of pronation-external rotation, including 4 cases of Maisonneuve fractures, and of the 4 cases of Maisonneuve fractures, there were 3 cases of double Maisonneuve fracture. The talar dislocation was anterior, neutral, and posterior within the distal tibiofibular joint in 10 cases, 7 cases, and 9 cases. Fibular fractures in 26 cases, medial malleolar fractures in 24 cases, deltoid ligament rupture in 2 cases, posterior malleolar fractures in 13 cases, and anterior malleolar fractures in 8 cases. All closed injuries were closed reduction and plaster fixation and all open injuries were emergently debridement and reduced under the tibial plafond in the emergency department. Surgical treatment was taken until the soft tissue conditions to be allowed. The reduction quality was assessed by postoperative radiography according to the criteria proposed by Burwell-Charnley. The function of the ankle joint was assessed by the ankle-hindfoot rating system of the American Orthopaedic Foot and Ankle Society (AOFAS), and the posttraumatic arthritis and objectively quantified was assessed using the Kellgren-Lawrence grading scale.Results:There were 4 cases were unreduced due to the tibial posterior tendon to flip through the ankle joint and dislocate anterior to the tibia through the interosseous membrane. Stabilization of fibular fractures were achieved with plate in 25 cases. There were 24 cases of medial malleolar fractures, and the fixation were achieved with cannulated screws in 23 cases and with K-wire fixation in 1 case. There were 12 cases of posterior malleolar fractures treated with open reduction and internal fixation including cannulated screws in 9 cases and antiglide plates in 3 cases. There were 7 cases of anterior malleolar fractures treated with open reduction and internal fixation including suture anchors in 1 case and cannulated screws in 6 cases. Stabilization of syndesmosis was achieved with syndesmotic screws in 14 cases and with TightRope in 2 cases. All patients were followed up for 20.23±9.70 months (range, 12-60 months). According to the Burwell-Charnley criteria of reduction quality, anatomic reduction was obtained in 22 cases, and satisfactory reduction was gained in 4 cases. All fractures healed in 16.31±3.64 weeks (range, 10-24 weeks). Functional examination of the ankle joint (angle measurement method): dorsiflexion average angle 10.38°±6.66°, plantarflexion average angle 34.04°±7.20°. At latest follow up, the AOFAS score was 83.30±13.94 (range, 24-100). Ten (38%) of 26 patients had radiographic evidence of posttraumatic ankle arthritis. According to the Kellgren-Lawrence grading scale criteria, there were grade I in 5 cases, II in 2 cases, III in 2 cases, and IV in 1 case. 2 cases of wound dishence were recovered through changing dressing and 2 cases of skin necrosis were recovered by skin graft and flap transposition respectively. There were no significant complications such as infection, nonunion, or implant failure.Conclusion:The transsyndesmotic ankle fracture dislocation, represents an exceptional pattern of high-energy fractures with significant syndesmotic disruption, and potential soft tissue compromise. Careful attention to radiographic findings can identify unique fracture characteristics relative to operative decision-making. Tibialis posterior tendon dislocation, a rare complication in the transsyndesmotic ankle fracture dislocation injuries, can impede anatomical reduction of the ankle mortise. The open reduction and internal fixation may be an optimal approach to treat transsyndesmotic ankle fracture dislocation injuries. However, the rate of posttraumatic arthritis is relatively high.

ABSTRACT

Objective:To explore the changes of peripheral blood Th17/Treg and serum cytokines in AECOPD patients with secondary pulmonary fungal infection.Methods:Selected the clinical data of 27 AECOPD patients who were admitted between January 2018 to March 2020 in the Department of Respiratory Medicine, Hai'an People's Hospital Affiliated to Nantong University with fungal infection (fungal infection group), and 58 AECOPD patients without fungal infection (non-fungal infection group) who received treatment in the hospital during the same period. Compared the general clinical data, peripheral blood Th17 and Treg cell levels, Th17/Treg ratio, interleukin-17 (IL-17), interleukin-23 (IL-23), interferon-γ (interferon-γ, IFN-γ), and transforming growth factor-β (TGF-β) levels. Meanwhile, compared the levels of Th17 and Treg cells in peripheral blood, the ratio of Th17/Treg and serum cytokines in patients with different infection severity in fungal infection group. The measurement data with normal distribution were compared by independent samplet t-test between the two groups, one-way ANOVA between multiple groups, LSD-t test for pairwise comparision, and χ 2 test for counting data. Results:In the 27 AECOPD patients with fungal infection group, the pathogen distribution was 65.52% (19/27) of candida albicans, 10.34% (3/27) of candida tropicalis,10.34% (3/27) of candida albicans, and 6.90% (2/27) of Aspergillus. The level of Th17 [(16.18±3.15) % and (12.34±2.64) %, t=5.87, P<0.001)], the ratio of Th17/Treg [(4.70±0.85) and (2.41±0.51), t=22.87, P<0.001] in Patients with fungal infection group were higher than those in the non-fungal group. The level of Treg [(3.42±0.42) % and (5.13±0.51) %, t=20.77, P<0.001] in Patients with fungal infection group was lower than those in the non-fungal group. The levels of IL-17 [(85.67±21.51) μg/L and (53.64±14.36) μg/L, t= 8.12, P<0.001], and IL-23 [(61.38±16.58) μg/L and (38.29±12.60) μg/L, t=7.10, P<0.001] in Patients with fungal infection group were higher than those in non-fungal infection group, but the levels of IFN-γ ((47.75±17.72) μg/L and (62.37±19.06) μg/L, t=3.37, P=0.001) and TGF-β ((110.34±26.03) μg/L and (131.40±35.03) μg/L, t=2.87, P=0.007) were lower than those in non-fungal infection group, and the differences were statistically significant. There were statistically significant differences in the ratio of Th17/Treg, and the levels of Th17, Treg cells and cytokine among patients with different infection severity in the fungal infection group. With the increase of infection severity, the levels of Th17 ((13.06±1.98)%, (15.94±2.11)%, (17.75±2.20)%, F=10.19, P<0.001), the ratios of Th17/Treg ((5.01±0.60), (5.66±0.69), (6.52±0.65), F=10.77, P<0.001), the levels of IL-17 ((63.39±11.64) μg/L,(78.66±12.82) μg/L, F=9.01, P=0.001), and IL-23 ((42.52±13.11) μg/L, (59.97±15.25) μg/L, (69.75±14.30) μg/L, F=7.41, P=0.003) were increase, the levels of Treg ((4.33±0.39)%, (3.32±0.42)%, (2.50±0.35)%, F=44.42, P<0.001), IFN-γ ((57.78±10.52) μg/L, (48.82±10.39) μg/L, (38.90±10.56) μg/L, F=6.50, P=0.006), TGF-β ((126.62±18.94) μg/L, (115.34±13.66) μg/L, (102.52±17.73) μg/L, F=4.25, P=0.026) were significantly decreased. Conclusion:The imbalance of Th17/Treg ratio and related serum cytokines play an important role in the process of lung fungal infection in AECOPD patients, and their imbalance is related to the severity of fungal infection. Therefore, the levels of Th17/Treg and serum cytokines should be closely monitored in AECOPD patients.

ABSTRACT

Objective To investigate the effect of compound Fufangteng mixture-containing serum on the proliferation of bone marrow mesenchymal stem cell (BMSC) and its mechanism. Methods Rat BMSC were isolated, cultured and purified in vitro by direct adherence method. Cell morphology was observed. Surface markers were identified by flow cytometry. The rats were treated with compound Fufangteng mixture at a dose of 3 mL/(kg·d) by gavage for 14 d, and then the drug-containing serum was collected. BMSC were divided into the blank control group, drug-containing serum group, Notch1 small interfering ribonucleic acid (siRNA) group and Notch1 siRNA+drug-containing serum group. The proliferation rate of BMSC was detected and the relative expression levels of Notch1 signaling pathway-associated messenger ribonucleic acid (mRNA) and proteins were measured in each group. Results Microscopic observation showed that the first generation BMSC were seen in the long spindle shape, and grown in the parallel or spiral pattern. The third generation BMSC positively expressed CD90 and CD44, whereas were negative for CD45. Compared with the blank control group, the proliferation rate of BMSC in the drug-containing serum group and Notch1 siRNA+ drug-containing serum group was significantly increased, whereas that of BMSC was significantly decreased in the Notch1 siRNA group (all P < 0.05). Compared with the Notch1 siRNA group, the proliferation rate of BMSC was significantly increased in the Notch1 siRNA+drug-containing serum group (P < 0.05). Compared with the blank control group, the relative expression levels of Hey1 and Delta-like ligand (DLL)1 mRNA and proteins were significantly up-regulated in the drug-containing serum group, whereas those were significantly down-regulated in the Notch1 siRNA group and Notch1 siRNA+drug-containing serum group (all P < 0.05). Compared with the Notch1 siRNA group, the relative expression levels of Hey1 and DLL1 mRNA and proteins were significantly up-regulated in the Notch1 siRNA+drug-containing serum group (all P < 0.05). Conclusions Compound Fufangteng mixture-containing serum may promote the proliferation of rat BMSC, and its mechanism is probably associated with the activation of Notch1 signaling pathway.

ABSTRACT

Objective:To measure the microdosimetric spectrum of carbon ion beam and calculate the relative biological effect (RBE) distribution, so as to provide reference for radiotherapy microdosimetric research.Methods:A silicon on insulator (SOI) microdosimeter was used to measure the microdosimetric spectrum of 12C ion beam, at 260 MeV/u, provided by Lanzhou Heavy Ion Accelerator National Laboratory. The measured pulse amplitude spectrum was converted to obtain the dose distribution. The microdosimetric spectra and RBE values at different polymethyl methacrylate depths were measured by the combination of different thickness PMMA. Results:The microdosimetric spectra of 12C ion beam at 260 MeV/u were measured at different PMMA depths, and the relationship between dose line energy yD and RBE and different PMMA depths was also obtained. The measurement result showed that the RBE value reached a peak of 2.6 at the PMMA depth of 116.5 mm, and decreased rapidly after the Bragg peak. However, the RBE value was still 1.3 at the trailing point, which was about twice as much as the entrance of the flat zone. Conclusions:This paper provides basic data for carbon ion beam microdosimetric spectroscopy through measurement. The RBE value of 12C ion beam gradually rises and reaches a peak with the increase of PMMA depth. After the Bragg peak position, it drops rapidly, but the biological effect at the tail cannot be ignored. At the same time, it reflects the dose fraction caused by different line energy intervals, and provides a reference for assessing the risk of heavy ion therapy for secondary cancer.

ABSTRACT

Objective:To estimate the physical dose of an over exposed person working for industrial radiography.Methods:The main exposure parameters were obtained. The exposure duration was 8 min. The exposure pattern was external exposure by isotropic point radioactive source. The radioactive activity was 2.183 TBq. In the present calculation, the Chinese reference adult voxel phantom was used, and the Monte Carlo simulation was performed using the program based on the secondary development of Geant4 to obtain the absorbed dose of each part of the victim.Results:The dose distribution in the victim′s hands was obtained. The doses to most areas of the palm were 2-10 Gy, and the doses to the fingers were 10-20 Gy. The equivalent doses to 23 tissues or organs of the exposed person were estimated to be in the range of 0.012-0.207 Gy.Conclusions:The physical dose estimation method could evaluate rapidly the local dose distribution of the victim′s key exposed body parts, and thus provide an important reference for medical treatment.

ABSTRACT

Organoids are tissue structures, generated from pluripotent stem cells and cultured in vitro, which form self-organize and recapitulate tissues with similar structure and function to the original organs. Organoids have similar appearance and function to the original tissues, and have been widely applied in basic research and clinical trial. At present, the organoids of liver, kidney, islet, brain, intestine and other organs have been successfully cultivated. The use of islet organoid is a hotspot in the field of organoid research. However, islet organoid is currently applied in basic research because rejection after organ transplantation and other issues remain unresolved. In this article, the origin, development and basic application of islet organoid were reviewed, aiming to provide reference for the transformation from basic research of islet organoid into clinical application as well as the treatment of diabetes mellitus.

ABSTRACT

Ulcerative colitis (UC) is a chronic refractory non-specific intestinal inflammatory disease that is difficult to be cured. The discovery of new ulcerative colitis-related metabolite biomarkers may help further understand UC and facilitate early diagnosis. It may also provide a basis for explaining the mechanism of drug action in the treatment of UC. Compound Sophorae Decoction (CSD) is an empirical formula used in the clinical treatment of UC. Although it is known to be efficacious, its mechanism of action in the treatment of UC is unclear. The purpose of this study was to investigate the changes in endogenous substances in UC rats and the effects of CSD on metabolic pathways using the metabonomics approach. Metabolomics studies in rats with UC and normal rats were performed using LC-MS/MS. Rats with UC induced using TNBS enema were used as the study models. Metabolic profiling and pathway analysis of biomarkers was performed using statistical and pathway enrichment analyses. 36 screened potential biomarkers were found to be significantly different between the UC and the normal groups; it was also found that CSD could modulate the levels of these potential biomarkers. CSD was found to be efficacious in UC by regulating multiple metabolic pathways.

ABSTRACT

Objective:To investigate the efficacy of modified Zhigancao decoction on Qi/ Yin-deficiency acute viral myocarditis and its effect on serum level of high mobility group box chromosomal protein 1 (HMGB-1). Methods:Eighty-eight patients with Qi/ Yin-deficiency acute viral myocarditis who received treatment in Chun'an Hospital of Traditional Chinese Medicine from July 2017 to December 2018 were included in this study. They were randomly assigned to undergo either standard conventional intervention (control group, n = 43) or treatment with modified Zhigancao decoction based on standard conventional intervention (observation group, n = 45) for 4 weeks. After treatment, serum levels of cardiac troponin I (cTnI) and HMGB1, traditional Chinese medicine symptom score, and clinical efficacy were compared between the two groups. Results:After 2 and 4 weeks of treatment, serum level of cTnI in the observation group was (590.22 ± 78.42) ng/L and (461.36 ± 52.44) ng/L, respectively, which was concurrently significantly lower than that in the control group, respectively [(621.41 ± 86.12) ng/L, (587.62 ± 67.94) ng/L, ( t2 weeks = 1.574, t4 weeks = 9.785, both P < 0.05). After treatment, traditional Chinese medicine symptom score in the observation group was significantly lower than that in the control group ( tfever = 27.650, tsore throat = 27.210, tpalpitation = 14.560, tvexation and chest tightness = 15.370, all P < 0.01). Total effective rate in the observation group was significantly higher than that in the control group [93.33% (42/45) vs. 72.09% (32/43), χ2 = 8.41, P < 0.05). After 2 and 4 weeks of treatment, serum level of HMGB1 in the observation group was concurrently significantly lower than that in the control group ( t2 weeks = 9.144, t4 weeks = 11.534, both P < 0.01). Conclusion:Modified Zhigancao decoction combined with conventional western medicine intervention for the treatment of Qi/ Yin-deficiency acute viral myocarditis exhibits great therapeutic effects possibly through downregulating serum level of HMGB1.

ABSTRACT

Objective To explore the prevalence and epidemiological characteristics of bronchial asthma in people over 40 years old in Hai'an. Methods The stratified random sampling method was used in this study. A questionnaire survey was conducted and pulmonary function measurement was performed among the residents over 40 years old in Hai'an, ​Jiangsu Province to analyze the prevalence and epidemiological characteristics of asthma. Results A total of 2 237 valid questionnaires were collected in the survey, and 116 patients with bronchial asthma were found, with an incidence rate of 5.19%. The prevalence of asthma was related to gender, age, family history, active and passive smoking, occupational exposure, childhood history of lung disease, history of respiratory allergies, and exposure to cooking fumes (P<0.05). Multivariate logistic regression analysis showed that being male (OR=0.637, 95%CI: 0.499~0.691) was a protective factor for asthma, while advanced age (OR=1.438, 95%CI: 1.207~1.972), active smoking (OR=1.795, 95%CI: 1.423~2.399), passive smoking (OR=2.098, 95%CI: 1.423~2.399), occupational exposure (OR=3.446, 95% CI: 2.175~6.290), childhood history of lung disease (OR=2.228, 95%CI: 1.337~4.491), history of respiratory allergies (OR=2.287, 95%CI: 1.535~5.219) were risk factors for asthma (P<0.05). Conclusion The prevalence rate of bronchial asthma in people over 40 years old in Hai'an was high. Advanced age, active and passive smoking, occupational exposure, a history of lung disease in childhood, and a history of respiratory allergies were related to asthma development. It is necessary to strengthen the prevention and treatment of asthma among high-risk population in clinical practice to reduce the incidence of asthma.

ABSTRACT

OBJECTIVE@#To investigate specific technique and clinical effects of closed folding top consolidation maneuver combined with splint fixation maneuver for consolidation and cedar bark external fixation splint for the treatment of double fractures of distal ulna and radius in children.@*METHODS@#From January 2017 to December 2019, 17 children with double fractures of distal ulna and radius were treated with closed folded apex consolidation maneuver, including 13 males and 4 females, aged from 4 to 11 years old with an average of (7.29±2.34) years old. The fractures were fixed with cedar bark splint and followed up for 6 months, and alignment of fracture was evaluated according to the latest X-rays by follow up, and function of the affected limbs was evaluated by Anderson forearm function evaluation criteria.@*RESULTS@#Fifteen of 17 children were successfully reset immediately, and 2 children were successfully reset again. The average fixed time was (25.00±3.35) days. At 6 months of follow up, 12 patients got excellent results, 3 good, 2 fair, and 0 poor according to Anderson forearm function evaluation criteria. The position of all children were larger than 3/4, and 10 children were received anatomical reduction, alignment of 4 children was less than 10°, 3 children was less than 15°. No complications such as fracture displacement, nonunion, compartment syndrome, and forearm rotation dysfunction occurred.@*CONCLUSION@#Restoration of distal radius double fracture in children with the combination of the closed folding and top fixation maneuver and splint fixation maneuver has advantages of higher success rate, lower complications, which could reduce operating difficultyand pain of patients.

ABSTRACT

Objective@#This study aimed to investigate the effects of @*Methods@#In this study, 0.1% DMG was supplemented in 20% casein diets that were either folate-sufficient (20C) or folate-deficient (20CFD). Blood and liver of rats were subjected to assays of Hcy and its metabolites. Hcy and its related metabolite concentrations were determined using a liquid chromatographic system.@*Results@#Folate deprivation significantly increased pHcy concentration in rats fed 20C diet (from 14.19 ± 0.39 μmol/L to 28.49 ± 0.50 μmol/L; @*Conclusion@#DMG supplementation exhibited hypohomocysteinemic effects under folate-sufficient conditions. By contrast, the combination of folate deficiency and DMG supplementation has deleterious effect on pHcy concentration.

ABSTRACT

Synaptic cell adhesion molecules (CAMs) are a type of membrane surface glycoproteins that mediate the structural and functional interactions between pre- and post-synaptic sites. Synaptic CAMs dynamically regulate synaptic activity and plasticity, and their expression and function are modulated by environmental factors. Synaptic CAMs are also important effector molecules of stress response, and mediate the adverse impact of stress on cognition and emotion. In this review, we will summarize the recent progress on the role of synaptic CAMs in stress, and aim to provide insight into the molecular mechanisms and drug development of stress-related disorders.

ABSTRACT

Objective:To investigate the effects of different concentrations of Astragali Radix containing serum on the expression of 24-hydroxylase(CYP24A1),1α-OHase(CYP27B1) mRNA and protein in rat bone marrow mesenchymal stem cells (BMSCs), and to explore the mechanism of primary osteoporosis (OP). Method:The experiment was divided into 6 groups,like normal group, model group, low ,middle and high dose group of Astragali Radix containing serum(20%,40%,60%),Vitamin D group. Cell proliferation toxicity assay(CCK-8) was used to detect the effect of different concentrations of Astragali Radix containing serum on survival rate of aging BMSCs.Real-time quantitative PCR(Real-time PCR) and Western blot was used to detect the expression of CYP24A1 CYP27B1 mRNA and protein in senile BMSCs osteogenic differentiation cells by different concentrations of Astragali Radix containing serum. Result:Compared with normal group, the proliferation and survival rate of BMSCs osteoblasts induced by D-galactose in model group was significantly lower than that in normal group (P<0.01). Compared with model group, medium and high dose groups and Vitamin D group could improve the proliferation and differentiation of aging BMSCs into osteoblasts in different degrees(P<0.01). The relative expression of CYP27B1 mRNA and protein in model group was significantly lower than that in normal group, while the relative expression of CYP24A1 mRNA and protein in model group was significantly higher than that in normal group. Compared with model group, high dose Astragali Radix containing serum group could increase the relative expression of CYP27B1 mRNA and protein, and decrease the relative expression of CYP24A1 mRNA and protein in a dose-dependent manner(P<0.01). Conclusion:The mechanism of different concentrations of Astragali Radix containing serum in the treatment of osteoporosis may be related to the regulation of CYP24A1, CYP27B1 mRNA and protein in the osteogenic differentiation of aging BMSCs.

ABSTRACT

OBJECTIVE@#To investigate the risk factors for cow's milk protein allergy (CMPA) among infants through a multicenter clinical study.@*METHODS@#A total of 1 829 infants, aged 1-12 months, who attended the outpatient service of the pediatric department in six hospitals in Shenzhen, China from June 2016 to May 2017 were enrolled as subjects. A questionnaire survey was performed to screen out suspected cases of CMPA. Food avoidance and oral food challenge tests were used to make a confirmed diagnosis of CMPA CMPA. A multivariate logistic regression analysis was used to investigate the risk factors for CMPA.@*RESULTS@#Among the 1 829 infants, 82 (4.48%) were diagnosed with CMPA. The multivariate logistic regression analysis showed that maternal food allergy (OR=4.91, 95%CI: 2.24-10.76, P6 months (OR=0.38, 95%CI: 0.17-0.86, P<0.05) were protective factors.@*CONCLUSIONS@#The introduction of complementary food at an age of <4 months, maternal food allergy, and antibiotic exposure during pregnancy are risk factors for CMPA in infants.
