ABSTRACT

Objective:To explore the efficacy of tracheotomy and nasal intubation in airways management in treatment of patients with respiratory failure caused by severe tetanus.Methods:A respective case series study was conducted to analyze the data of 92 patients with respiratory failure caused by severe tetanus admitted to Jiangxi Chest Hospital from January 2012 to December 2019. There were 60 males and 32 females, aged 23-81 years [(47.5±14.1)years]. Overall 43 patients underwent tracheotomy (tracheotomy group), and 49 patients underwent nasal intubation (nasal intubation group). The blood gas related indexes (PaO 2, PaCO 2), catheter retention time, incidence of complications such as airway bleeding, nasosinusitis, catheter blockage and ventilator-associated pneumonia (VAP), and clinical outcome were compared between the two groups. Results:After mechanical ventilation, the PaO 2 and PaCO 2 in both groups were significantly improved ( P<0.01), with no significant difference between groups ( P>0.05). Both groups were similar regarding the catheter indwelling time, catheter blockage, airway bleeding and nasosinusitis ( P>0.05). The incidences of VAP and catheter blockage after extubation in tracheotomy group [12%(5/43), 12%(5/43)] were significantly different from those in nasal intubation group [0%(0/49), 31%(15/49)] ( P<0.05). There were 3 deaths in each group, with the mortality rate of 7% (3/43) in tracheotomy group and of 6% (3/49) in nasal intubation group ( P>0.05). Both groups of live tetanus patients were cured. After 3-month follow-up, the tetanus was cured in the two groups. Conclusions:The tracheotomy and transnasal tracheal intubation are optional for severe tetanus patients with respiratory failure. The former has airway and tissue trauma, but it is convenient for mechanical ventilation management, especially indicated for patients with severe convulsions, angular arch reflexes, poor sedation, and continuous application of muscle relaxants. Nasal intubation is relatively non-invasive, simple and fast method, but the prevention and monitoring of VAP requires higher requirements.

ABSTRACT

microRNA (miRNA) is a class of endogenous ~21nt non-coding single-strand small RNAs which play important roles in plant growth and development, signal transduction, stress response, and secondary metabolism. In recent years, a large number of miRNAs have been identified in various medicinal plants, and the regulatory effects of these miRNAs have been preliminarily studied. In medicinal plants, most of the active components are secondary metabolites, so it is of great significance to study the regulatory effects of miRNA on the formation of secondary metabolites. In this paper, the general research methods of plant miRNA and the research progress of medicinal plant miRNA and their regulatory effects on the formation of bioactive metabolites were reviewed, and the future direction of medicinal plant miRNA was prospected, so as to provide reference for the future research of medicinal plants.

ABSTRACT

BACKGROUND: Cx43 plays an important role in human congenital heart disease. However, there is still no consistent conclusion about the formation mechanism of cardiac malformation in Cx43 knockout mouse embryos. OBJECTIVE: To investigate the cardiac development defects and the migration and differentiation of progenitor cells of the second heart field and cardiac neural crest in Cx43 knockout mouse embryo. METHODS: Serial sections of Cx43 gene knockout homozygous (Cx43-/-) mouse and Cx43 wild-type (Cx43+/+) mouse embryos from embryonic day (ED) 10 to ED13 were made for immunohistochemical and immunofluorescent staining, and three-dimensional reconstruction of the heart. RESULTS AND CONCLUSION: (1) In Cx43 gene knockout mouse embryos at ED10-ED11, Isl1 positive second heart field cells in the ventral mesenchyme of the foregut extended through the area between the bilateral arch arteries to the dorsal wall of pericardial cavity. Meanwhile, Isl1 positive cells in the core mesenchyme of the branchial arches were continuous with those in the dorsal wall of pericardial cavity and the distal wall of the outflow tract. At ED13, the distribution of Isl1 positive cells was observed in the wall of the ascending aorta and pulmonary trunk as well as the wall of the left and right outflow tracts of the septated ventricles. However, compared with wild-type mouse embryos, fewer Isl1 positive second heart field cells were found in Cx43 gene knockout mouse embryos (P < 0.01). (2) During ED10 to ED11, Ap2α positive neural crest cells were still found in the wall of the arch artery and the dorsal and ventral walls of the aortic sac in Cx43 gene knockout mouse embryos, but the number of neural crest cells was less than that of wild-type mouse embryos (P < 0.01). (3) These results indicate that the migration path and distribution pattern of Isl1 positive second heart field cells and Ap2α positive cardiac neural crest cells are similar between the Cx43 gene knockout and wild-type mouse embryos, but the number of two kinds of migrating cells is reduced after Cx43 gene knockout. This suggests that in addition to cardiac neural crest derived cells, the decrease of second heart field progenitor cells might be involved in the formation of outflow tract malformations in Cx43 knockout mouse embryos.

ABSTRACT

BACKGROUND@#There were few studies on real-world data about autologous hematopoietic stem cell transplantation (auto-HSCT) or allogeneic HSCT (allo-HSCT) in peripheral T-cell lymphoma (PTCL). This study aimed to investigate the clinical outcomes of patients who received auto-HSCT or allo-HSCT in China.@*METHODS@#From July 2007 to June 2017, a total of 128 patients who received auto-HSCT (n  = 72) or allo-HSCT (n  = 56) at eight medical centers across China were included in this study. We retrospectively collected their demographic and clinical data and compared the clinical outcomes between groups.@*RESULTS@#Patients receiving allo-HSCT were more likely to be diagnosed with stage III or IV disease (95% vs. 82%, P = 0.027), bone marrow involvement (42% vs. 15%, P = 0.001), chemotherapy-resistant disease (41% vs. 8%, P = 0.001), and progression disease (32% vs. 4%, P < 0.001) at transplantation than those receiving auto-HSCT. With a median follow-up of 30 (2-143) months, 3-year overall survival (OS) and progression-free survival (PFS) in the auto-HSCT group were 70%(48/63) and 59%(42/63), respectively. Three-year OS and PFS for allo-HSCT recipients were 46%(27/54) and 44%(29/54), respectively. There was no difference in relapse rate (34%[17/63] in auto-HSCT vs. 29%[15/54] in allo-HSCT, P = 0.840). Three-year non-relapse mortality rate in auto-HSCT recipients was 6%(4/63) compared with 27%(14/54) for allo-HSCT recipients (P = 0.004). Subanalyses showed that patients with lower prognostic index scores for PTCL (PIT) who received auto-HSCT in an upfront setting had a better outcome than patients with higher PIT scores (3-year OS: 85% vs. 40%, P = 0.003). Patients with complete remission (CR) undergoing auto-HSCT had better survival (3-year OS: 88% vs. 48% in allo-HSCT, P = 0.008). For patients beyond CR, the outcome of patients who received allo-HSCT was similar to that in the atuo-HSCT group (3-year OS: 51% vs. 46%, P = 0.300).@*CONCLUSIONS@#Our study provided real-world data about auto-HSCT and allo-HSCT in China. Auto-HSCT seemed to be associated with better survival for patients in good condition (lower PIT score and/or better disease control). For patients possessing unfavorable characteristics, the survival of patients receiving allo-HSCT group was similar to that in the auto-HSCT group.

ABSTRACT

Objective:To explore the relationship between breastfeeding knowledge, self-efficacy and exclusive breastfeeding behavior among mothers of one-month old babies. Methods:Random sampling method was conducted for choosing 5 out of 13 community service health centers in Jiading district of Shanghai. A cross-sectional online survey was conducted among the mothers. Results:A total of 456 valid questionnaires were received, the full score of breastfeeding knowledge was set at 60, with an average of 47.17±5.65, ranging from 12 to 60. The full score of self-efficacy was set at 70, with an average of 47.70±14.48, ranging from 14 to 70. The exclusive breastfeeding rate of one-month old infants was 55.3%(252/456). Multivariate logistic analysis showed that mothers with higher scores of breastfeeding knowledge had significantly higher rate of exclusive breastfeeding (OR=1.717, 95%CI 1.034-2.851, P=0.037). Those with higher scores of breastfeeding self-efficacy also had significantly higher rate of exclusive breastfeeding (OR=5.736, 95%CI 3.455-9.522, P=0.001). Conclusions:The breastfeeding knowledge and self-efficacy of mothers of one-month old babies were significantly associated with the rate of exclusive breastfeeding. Medical staff should strengthen the delivery and cultivation of breastfeeding knowledge and skills for mothers to improve breastfeeding self-efficacy, and ultimately promote the rate of exclusive breastfeeding.

ABSTRACT

Sunscreen products have been widely used with the increase in public awareness of sun protection. As sunscreens are structurally stable and resistant to degradation, the concern for their biotoxicity and impact on marine environment has been heightened increasingly, and several countries and regions have successively issued bans on relevant sunscreen products. However, these bans have not yet affected the key international rules and regulations related to sunscreen products. The risks of different sunscreens to marine ecosystems and potential risks to human themselves still need to be evaluated through further multidisciplinary researches.

ABSTRACT

BACKGROUND@#One inevitable shortcoming of non-invasive prenatal screening (NIPS)/cell-free DNA (cfDNA) sequencing is the uninterpretable ("no-call") result, which is mainly caused by an insufficient fetal fraction. This study was performed to investigate the factors associated with a successful second NIPS in these cases and determine the optimal management for women with initial no-call results.@*METHODS@#We retrospectively analyzed the data of women who underwent NIPS with initial no-call results due to an insufficient fetal fraction from 2017 to 2019 in our center. We compared these women's maternal and pregnancy information with the data of women who had attained a successful second NIPS result and women who had received no-call results for a second time.@*RESULTS@#Among the 33,684 women who underwent NIPS, 137 with a no-call result underwent a retest. Comparison between the 87 (63.50%) women with a successful retest and the other 50 (36.50%) women showed a significant difference in both the initial fetal fraction and maternal body mass index (BMI), whereas the other factors showed no significant differences. In addition, with an initial fetal fraction of < 2.00%, the retest success rate was very limited.@*CONCLUSIONS@#We identified two major factors associated with a successful NIPS retest: the initial fetal fraction and the maternal BMI. These findings suggest the need for specialized management for this subset of women and would be instructional for the counseling for these women.

ABSTRACT

In China, the aging of the population is becoming increasingly serious. Common diseases of the elderly, such as sarcopenia and metabolic syndrome, have gradually become key factors affecting their quality of life. Sarcopenia is a decline in skeletal muscle mass and function associated with aging. Metabolic diseases such as obesity, hypertension and diabetes play an important role in the development of sarcopenia. In recent years, the relationship between sarcopenia and metabolic syndrome has also become a research hotspot, but there is still a lack of strong evidence on whether they are a risk factor for each other. This paper summarizes the epidemiological data of the relationship between sarcopenia and metabolic syndrome in the last 5 years, and reviews the epidemiological background, research status and potential links in biological mechanism of sarcopenia and metabolic syndrome. There is a significant correlation between sarcopenia and metabolic syndrome that may share similar biological mechanisms. However, there are still some limitations in this study. In addition, the methods of early screening and diagnosis of sarcopenia should be continuously explored to achieve the purpose of simplicity, rapidity and efficiency. This review aims to raise the population's awareness of chronic syndromes sarcopenia and metabolic syndrome, and to provide theoretical support for further research on their relevance.

ABSTRACT

OBJECTIVE@#To observe the effect of San-Ao Decoction (, SAD) on water metabolism of bronchial asthra model mice.@*METHODS@#Forty-five female BALB/c mice were randomly divided into control, model and SAD groups by a random number table, 15 mice in each group. A composite method with ovalbumin (OVA) sensitization and challenge was developed to establish bronchial asthma model. Mice in the control group were intraperitoneally injected with distilled water without aerosol inhalation challenge. On day 15-22, 0.3 mL SAD was administered via gastric route in SAD group, one time per day, while an equivalent volume of normal saline was used for gastric administration in the control and model groups. Changes in airway resistance in the inspiratory phase (RI-R-Area) were detected using an AniRes2005 system, and 5-h urine output was collected by metabolic cages. Histopathological changes in lung and kidney were observed by hematoxylin-eosin staining. mRNA expressions of aquaporin (AQP) 1 and AQP2 in kidney were detected by reverse transcription-polymerase chain reaction, and the protein expressions of AQP1 and AQP2 in kidney were detected by immunohistochemistry. Enzyme-linked immune sorbent assay was used to detect the OVA-specific endothelium-1 (ET-1), antidiuretic hormone (ADH), atrial natriuretic peptide (ANP), prostaglandin E@*RESULTS@#Compared with the control group, the serum IgE level in model group increased (P<0.01). Following the pathologic changes in lung tissue, no significant change in kidney tissue was observed among 3 groups. Compared with the control group, the mice in the model group showed elevated airway resistance during inhalation phase, higher mRNA and protein expression levels on AQP1 and AQP2 in kidney tissue and higher ET-1 levels in serum, lung and kidney tissues, ADH and ANP in lung and serum, PGE@*CONCLUSION@#San-Ao Decoction can regulate the urine volume through regulating AQP1 and AQP2 expression, and the expression of these in the kidneys might be regulated by ET-1, NO and Ang II.

ABSTRACT

Objective@#To evaluate the efficacy of cell free DNA (cf-DNA) screening in prenatal care by analyzing the follow-up information and pregnancy outcomes.@*Methods@#All cf-DNA cases conducted in Women′s Hospital of Nanjing Medical University from August 2011 to December 2017 were enrolled. The general information of the pregnancies, cf-DNA results, confirmatory testing results, and the follow-up results were collected. The pregnancy outcomes were analyzed in cases with low risk cf-DNA results as well as with high risk results for common trisomies, which were trisomy 21 (T21), trisomy 18 (T18), and trisomy 13 (T13). The sensitivity, specificity, positive predictive value and negative predictive value of cf-DNA screening were calculated.@*Results@#(1) A total of 43 615 cf-DNA cases were involved, with 44 cases (0.10%, 44/43 615) test failure results, 314 cases (0.72%, 314/43 571) high risk results for common trisomies and 43 257 cases (99.27%, 43 257/43 571) low risk results. (2) Among 277 cases (88.21%, 277/314) high risk cases were successfully followed up, and 228 cases (82.31%, 228/277) underwent invasive confirmatory prenatal diagnosis. In the low risk results, 36 826 cases (85.13%, 36 826/43 257) were successfully followed up, and 572 (1.55%, 572/36 826) cases were found to have adverse pregnancy outcomes, among which 4 false negative cf-DNA results were confirmed. (3) In the 37 103 successfully followed up cf-DNA cases, the sensitivity for T21, T18, T13 were calculated as 97.96%, 96.67% and 100.00%, respectively; the specificity for T21, T18, T13 were calculated as 99.96%, 99.95% and 99.95%, respectively. The positive predictive value for T21, T18, T13 were calculated as 90.57%, 63.04% and 17.39%, respectively. The negative predictive value for T21, T18, T13 were calculated as 99.99%, 99.98% and 100.00%.@*Conclusions@#Cf-DNA is effective in detecting common trisomies, with a high sensitivity and specificity. However, the follow-up information revealed several potential limitations in current clinical practice, such as a number of cases with high risk results rejected invasive confirmatory testing, as well as the genetic diagnostic results for most low risk cases with an adverse pregnancy outcome aren′t obtained. Genetic counseling and the follow-up for all the cf-DNA cases should be emphasized in the future.

ABSTRACT

Objective:To investigate the MRI features of progressive multifocal leukoencephalopathy (PML) in acquired immunodeficiency syndrome (AIDS) patients, and to provide evidence for clinical diagnosis, evaluation and staging.Methods:Form Janurary 2016 to April 2018, 11 AIDS patients with clinical diagnosis of PML were enrolled at Zhongnan Hospital of Wuhan University. A total of 25 MRI examination data of 11 patients (5 patients underwent multiple examinations) were reviewed. The distribution, morphology and signal characteristics of the lesions were analyzed, and the changes of the lesions between multiple MRI examinations were compared. The lesions of all 25 MR images were staged according to MR features.Results:Typical image findings of PML included confluent, bilateral but asymmetric distributed, supratentorial white matter abnormal signal lesions. The parietal lobe was most commonly involved, followed by the frontal lobe. The lesions often showed hypointensity on T 1 and hyperintensity on T 2 weighted images. No obvious mass effect or enhancement was found. In advanced stage, multifocal white matter lesions were enlarged in size and more confluent, displaying large patchy abnormal signal intensity, with gradually involving the deep white matter, and occasionally combing with gray matter and cerebellar lesions. The disease showed heterogenous signal intensity due to necrosis in the lesion. The newly appeared lesions showed obvious diffusion restriction, demonstrating high signal intensity on diffusion weighted imaing with low apparent diffusion coefficient value. The main finding of the later stage was necrosis, with focal asymmetric brain atrophy was observed. Conclusions:PML in AIDS patients has characteristic MRI findings, and MRI features varies in different stages. MRI can be helpful in clinical diagnosis, evaluation and staging of PML.

ABSTRACT

Objective:To explore the MRI features of neonatal deep cerebral arterial infarctions.Methods:The medical and MRI datas of 23 neonates with deep cerebral arterial infarctions from January 2011 to December 2018 in Beijing Children′s Hospital, Capital Medical University were retrospectively analyzed. Both 11 males and 12 females with ages between 1-28 d were recruited and MRI were performed within 2-20 d after symptom onset. The MRI featurs including location, morphology, signal characteristics, enhancement features and other accompanied signs were reviewed.Results:A total of 15 cases with arterial infarction and 8 cases with complication of purulent meningitis were identified. The median age at presentation were 2 d and 7 d respectively. The unilateral involvement were demonstrated in all neonates with arterial infarctions. Among them, 11 had deep infarcts and the main branch of the middle cerebral artery was involved in 4 neonates. MRI showed slightly hypo-intensity on T 1WI and slightly hyper-intensity on T 2WI with indistinct boundary and focal punctate hyper-intensity on T 1WI and hypo-intensity on T 2WI. In 8 cases secondary to purulent meningitis, unilateral involvement was found in 5 cases and bilateral involvement in 3 cases. All cases showed hypo-intensity on T 1WI and hyper-intensity on T 2WI with indistinct boundary. Among them, 7 cases were heterogeneous, with small cystic changes which appeared as slightly hyper-intensity on T 1WI and slightly hypo-intensity on T 2WI peripherally, as well as nodular or patchy restricted diffusion. Marked swelling of the lesion was found in 6 cases. Multiple patchy or ring enhancement was revealed in 5 cases. Iso-intensity and restricted diffusion in posterior horn of the lateral ventricle were found in 2 cases. Restricted diffusion in frontotemporal subarachnoid space was found in 5 cases. One case showed subdural effusion. Conclusion:Neonatal deep cerebral arterial infarctions have certain characteristic appearance on MRI. Lesions secondary to purulent meningitis can be bilateral involvement with heterogeneous MRI intensities, and different period of infarction signs could be found concurrently. MRI is beneficial to the differential diagnosis.

ABSTRACT

Resin-containing drugs in Dracaena from four different appearances were analyzed by headspace sampling-gas chromatography-mass spectrometry(HS-GC-MS) metabolomics technique and hierarchical clustering analysis(HCA) chemometrics method. This study was to analyze differential volatile components in resin-containing drugs in Dracaena from different appearance and metabolic pathways. The results of partial least squares discriminant analysis(PLS-DA) and HCA analysis indicated that there was little difference in volatile components between fiber-rich sample and hollow cork cambium sample, however, the volatile components in the two samples compared with whole body resin-containing sample and resin-secreting aggregated sample had a large metabolic difference. Twenty differential metabolites were screened by VIP and P values of PLS-DA. The content of these differential metabolites was significantly higher in whole body resin-containing sample and resin-secreting aggregated sample than in fiber-rich sample and hollow cork cambium sample. Sixteen significant metabolic pathways were obtained through enrichment analysis(P<0.05), mainly involved in terpenoids biosynthesis and phenylpropanoid metabolism. This result provided a reference for further study of resin formation mechanism of resin-containing drugs in Dracaena from different appearances. At the same time, it also provided a reference for establishing a multi-index quality evaluation system.

ABSTRACT

Objective:To observe the effects of sling exercise therapy on muscle strength of pelvic floor in patients with postpartum stress urinary incontinence. Methods:From February, 2018 to February, 2019, 90 patients diagnosed as postpartum stress urinary incontinence 42 days after delivery were randomly divided into control group (n = 45) and observation group (n = 45). The control group received Kegel training, and the observation group received sling exercise therapy, for a month. The electromyogram of pelvic floor was measured before and after treatment, and the clinical efficacy was evaluated at the end of the treatment. Results:The electromyogram of pelvic floor increased in both groups after treatment (t > 3.879, P < 0.01), and increased more in the observation group than in the control group (P < 0.05). The rate of improvement was 93.33% in the observation group, which was more than 75.56% in the control group (χ2 = 13.83, P < 0.05). Conclusion:Sling exercise therapy can more effectively improve the muscle strength of pelvic floor for patients with postpartum stress urinary incontinence, and relieve the symptoms of overfall.

ABSTRACT

Objective To explore the revision strategy of the malunited tibial plateau fracture and to analysis the main points of four common revision operations and the clinical effect. Methods From January 2012 to December 2016, 18 patients (5 males and 13 females) aged 35-60 years (average 49.7 years) underwent tibial plateau revision surgery in our hospital were col?lected. The time from the second revision operation to the first operation was 2-24 months (average 10.4 months). Our revision strategies were as follows: Firstly, to determine whether there is an infection or not. If there was infection, we changed the original internal fixation to external fixator to control infection. Secondly, todetermine whether the patient could suffer re-reduction and in?ternal fixation. If the patient was older (>65 years old) or with severe local bone defect, total knee arthroplasty should be per?formed. Thirdly, patients were divided into four operation modes according to the tibial plateau fracture malunion type: 1. the origi?nal fracture line osteotomy; 2. the tibial tubercle+original fracture line osteotomy; 3. tibial metaphyseal window-rod reduction; 4. the osteotomy of fibula head and original fracture line osteotomy. Results All patients were followed up for 12-30 months (aver?age 16.8 months), and the operation time was 120-300 min (average 185 min). 2 cases were infected before operation and the origi?nal internal fixation were removed to instead of external fixator;1 patient underwent total knee arthroplasty; 3 cases were treated with metaphyseal open window-rod reduction and internal fixation; 6 cases were operated with the original fracture line osteotomy and internal fixation; 4 cases were treated with tibial tubercle osteotomy+original fracture line osteotomy and internal fixation; 2 pa?tients underwent fibular head osteotomy+original fracture line osteotomy and internal fixation. All patients achieved bony union at the last follow?up. The healing time was 3-6 months (mean 3.6 months). The postoperative knee Rasmussen score was 19-29 (aver?age 22.9), compared with average 14.4 points before operation (t=-10.169, P=0.001). The postoperative range of motion of knee joint was 60-110 degrees (mean 94.5 degrees), compared with average 55 degrees before operation (t=-5.773, P=0.001). The post?operative VAS pain score was average 1.1 points, compared with average 4.2 points before operation (t=8.960, P=0.001). Fracture reduction was excellent in 12 cases and good in 5 cases, with the excellent and good rate of 100%. 3 patients still had 2mm col?lapse on the articular surface, while 3 patients still had mild valgus (less than 5 degrees). There were 2 cases of superficial infec?tion of the wound surface after operation. Conclusion It was difficult to revise the malunion of tibial plateau fracture and it was necessary to make a detailed operation plan before the operation. Satisfactory clinical effects could be obtained for the patients by correct revision strategy. The key to success was the proper revision strategy which was adopted according to the different charac?teristics of the tibial plateau fracture malunion of the patients.

ABSTRACT

Objective@#To investigate the detection of thyroid nodules and related risk factors in nuclear power workers, and to provide scientific evidence for thyroid protection of nuclear power workers.@*Methods@#In December 2018, select 295 workers of a nuclear power production enterprise and 238 administrative staff of it, and select 250 staff members of a thermal power generation enterprise 70 kilometers away from the nuclear power station to conduct thyroid ultrasound examination and questionnaire survey for single factor. Analysis and further multivariate logistic regression analysis were used to study the risk factors of thyroid nodules in the population.@*Results@#Women and smoking history were independent risk factors for the increased incidence of thyroid nodules in the study population; three shifts work pattern was an independent risk factor for the increased prevalence of thyroid nodules in nuclear power workers (P<0.05) , and other factors such as the history of nuclear exposure had no significant correlation with thyroid nodules (P>0.05) .@*Conclusion@#Nuclear exposure has little effect on the prevalence of thyroid nodules in nuclear power workers.

ABSTRACT

OBJECTIVE@#To evaluate the effect of zoledronate acid (ZA) on the proliferation and osteogenic differentiation of rat mesenchymal stem cells (BMSCs).@*METHODS@#The BMSCs isolated from the SD rats were cultured with different concentrations of ZA (1, 5, 10, and 20 μmol·L), and the contro1 group received the same volume of culture medium but without ZA. Cell counting kit-8 was used to detect proliferation activity in each group. Alkaline phosphatase (ALP) staining and alizarin red staining were used to detect the osteogenic differentiation ability in each group. The gene expression levels of ALP, bone morphogenetic protein-2 (BMP-2), typeⅠcollagenase (COL-Ⅰ), runt-related transcription factor-2 (Runx-2), zinc finger structure transcription factor (Osx), osteocalcin (OCN), and osteopontin (OPN) were evaluated by real-time quantitative polymerase chain reaction (qRT-PCR).@*RESULTS@#Zoledronate at 1 μmol·L⁻¹ concentration had no effect on the proliferation and osteogenic differentiation of BMSCs. No significant difference was observed between this group and the control group (P>0.05). When the ZA concentration was more than 1 μmol·L⁻¹, ZA inhibited the proliferation and osteogenic differentiation of BMSCs, and the effect was concentration dependent. The difference between each group and the control group was statistically significant (P<0.05). At ZA concentration of 5 μmol·L⁻¹, ZA enhanced the expression of ALP, BMP-2, COL-Ⅰ, Runx-2, Osx, OCN, and OPN (P<0.05). However, at ZA concentration of more than 5 μmol·L⁻¹, the expression levels of osteogenicrelated genes in each group was lower than those of the control group (P<0.05).@*CONCLUSIONS@#Low ZA concentration has no effect on the proliferation and osteogenic differentiation of BMSCs. ZA at 5 μmol·L⁻¹ concentration inhibits the proliferation but promotes the osteogenic differentiation of BMSCs. High ZA concentration inhibits the proliferation and osteogenic differentiation of BMSCs.
