ABSTRACT

Sclerostin, a protein secreted from osteocytes, negatively regulates the WNT signaling pathway by binding to the LRP5/6 co-receptors and further inhibits bone formation and promotes bone resorption. Sclerostin contributes to musculoskeletal system-related diseases, making it a promising therapeutic target for the treatment of WNT-related bone diseases. Additionally, emerging evidence indicates that sclerostin contributes to the development of cancers, obesity, and diabetes, suggesting that it may be a promising therapeutic target for these diseases. Notably, cardiovascular diseases are related to the protective role of sclerostin. In this review, we summarize three distinct types of inhibitors targeting sclerostin, monoclonal antibodies, aptamers, and small-molecule inhibitors, from which monoclonal antibodies have been developed. As the first-in-class sclerostin inhibitor approved by the U.S. FDA, the monoclonal antibody romosozumab has demonstrated excellent effectiveness in the treatment of postmenopausal osteoporosis; however, it conferred high cardiovascular risk in clinical trials. Furthermore, romosozumab could only be administered by injection, which may cause compliance issues for patients who prefer oral therapy. Considering these above safety and compliance concerns, we therefore present relevant discussion and offer perspectives on the development of next-generation sclerostin inhibitors by following several ways, such as concomitant medication, artificial intelligence-based strategy, druggable modification, and bispecific inhibitors strategy.

ABSTRACT

Acupoint autohemotherapy at bilateral Zusanli (ST36) and Xuehai (SP10) was used to treat a 26-year-old female patient who had suffered from recalcitrant atopic eczema (AE) for five years. The treatment was applied at a frequency of once per week for the first month, followed by a three-month period of once every other week. At the end of treatment, the patient's AE symptoms were entirely resolved, and by the end of a six-month follow-up her immunoglobulin E level had returned to the normal range. Further, there was no relapse of AE symptoms during the six-month follow-up. Therefore, we hypothesized that after the repeated treatments the local inflammatory reaction induced by autologous blood injection triggered a local immune response, followed by a systemic immune response after the repeated treatment, finally leading to the anti-inflammation and immunomodulation effects. This case suggests that acupoint autohemotherapy could be used as an effective complementary treatment for recalcitrant AE, especially in cases where other treatments have failed. Further comparative studies are needed to corroborate the value and mechanisms of this therapy.

ABSTRACT

OBJECTIVE: To analyze the relationship between the neurobehavioral functions of individuals exposed to low-level lead and the levels of serum copper-related proteins glutathione S-transferase M1(GSTM1), hypoxia inducible factor-1 alpha(HIF1α), cyclooxygenase 1(COX1) and metallothionein(MT), and to screen biomarkers for changes in neurobehavioral function caused by occupational lead exposure. METHODS: A total of 194 workers who exposed to low-level lead(lead-exposed group) and 120 workers without lead exposure(control group) were selected from a battery factory as the research subjects by judgment sampling method. The inductively coupled plasma-mass spectrometry was used to determine blood lead levels of the two groups, and the State of Mood Scale(POMS) was investigated to assess the emotional state. The computerized neurobehavioral evaluation system in Chinese version 3(NES-C3) was used to test the neurobehavioral ability index(NAI) of related indicators of learning memory and mental activity. Enzyme-linked immunosorbent assay was used to detect the levels of copper-related protein in serum. After using principal component analysis to extract the principal components of emotional state, learning memory and mental activity, multiple linear regression was used to analyze the influencing factors of neurobehavioral function. RESULTS: The blood lead level of the lead-exposed group was increased [(57.15±11.12) vs(177.86±80.04) μg/L, P<0.01], and the incidence of symptoms such as dizziness, memory loss, sleep disturbance, fatigue, weakness, cold sweats in extremities, cold extremities, tingling of extremities, tingling sensation in the distal extremities, tetany, instability of holding things, metallic taste in the mouth, nausea and vomiting, anorexia, constipation, abdominal distension, abdominal pain, toothache/tooth loosening were increased(all P<0.01) compared with the control group. Meanwhile, the scores of tension-anxiety, depression-dejection, fatigue-inertia, anger-hostility, confusion-bewilderment of POMS were increased(all P<0.01), and the scores of vigor-activity were decreased(P<0.01). The NAI of the lead-exposed individuals in the NES-C3 test of 6 indicators(series addition and subtraction, visual retention, memory scanning, listening to digital breadth, visual simple reaction time, target tracking) were lower than that of the control group(all P<0.01). The serum levels of GSTM1 and HIF1α of the lead-exposed group decreased(all P<0.01), and the COX1 and MT levels increased(all P<0.01) compared with the control group. The serum GSTM1, HIF1α, COX1 and MT of the lead-exposed group were correlated with their emotional state, learning and memory and mental activity to varying degrees(all P<0.05). The results of multiple stepwise linear regression showed that serum COX1 level was an independent influencing factor of emotional state(P<0.01), serum GSTM1, COX1 and lead working years were independent influencing factor of learning and memory(all P<0.05), and work length with lead exposure and alcohol consumption was an independent influencing factor of mental activity(all P<0.05). CONCLUSION: Low-level lead exposure can cause central nervous system symptoms in workers, and the change in neurobehavioral function and serum levels of copper-related proteins GSTM1, HIF1α, COX1 and MT. Serum levels of GSTM1 and COX1 can be used as candidate biomarkers for indicating neurobehavioral function caused by lead exposure.

ABSTRACT

OBJECTIVE@#To detect pathogenic variants in a pedigree affected with propionic acidemia (PA).@*METHODS@#The proband was subjected to high-throughput next-generation sequencing. Suspected variants were validated by Sanger sequencing of his family members. mRNA was extracted from peripheral blood lymphocytes from the proband's father in order to verify the impact of the splicing variant by RT-PCR combined with Sanger sequencing. The pathogenicity of the missense variant was predicted by using PolyPhen-2, Mutation Taster, SIFT, COBALT and HOPE software.@*RESULTS@#The proband was found to harbor compound heterozygous variants of the PCCB gene, namely c.184-2A>G and c.733G>A (p.G245S), which were respectively inherited from his father and mother. RT-PCR combined with Sanger sequencing confirmed skipping of exon 2 during transcription. Bioinformatic analysis indicated the c.733G>A (p.G245S) variant to be damaging.@*CONCLUSION@#The two variants of the PCCB gene probably underlay the disease in this patient. Above findings have enriched the spectrum of PCCB gene variants.

ABSTRACT

Circular RNAs (circRNAs), a novel type of non-coding RNAs (ncRNAs), are generated from pre-mRNA by covalently backsplicing of a downstream 5′ splice donor site onto an upstream 3′ splice acceptor site. Recent studies have shown that circRNAs have diverse biological functions, such as acting as a miRNA sponge to repress miRNA function, participating in splicing of target genes and translating genes into protein. These functions are involved in pathogenesis and progression of many diseases, including viral infection. In this review, we provided a brief introduction on the biological characteristics and functions of circRNAs, and summarized recent findings on the emerging roles of circRNA in viral infections, which might provide a new angle to study pathogenic characteristics and to understand the virus-host interaction mechanism.

ABSTRACT

Objective:To explore the role of interleukin (IL)-9 and other T helper (Th) cell-related cytokines in the pathogenesis of acute anterior uveitis.Methods:A cross-sectional study was conducted.Thirty-six patients (36 eyes) with acute anterior uveitis who were treated at Gansu Provincial Hospital from May 2018 to May 2019 and 40 matched healthy subjects (40 eyes) who had no eye diseases or systemic diseases in the same period were enrolled as the acute anterior uveitis group and healthy control group, respectively.The disease severity of the subjects in the acute anterior uveitis group was graded and the subjects were divided into mild, moderate and severe groups according to the grading.Serum of all subjects was collected to determine the concentration of serum IL-9, IL-17, transforming growth factor-β 1 (TGF-β 1), interferon-γ (IFN-γ), IL-4, IL-35 and IL-22 by enzyme linked immunosorbent assay (ELISA) method.Spearman rank correlation analysis was used to evaluate the relationship between IL-9 concentration and other Th cell-related cytokines.This study adhered to the Declaration of Helsinki.The study protocol was approved by an Ethics Committee of Gansu Provincial Hospital (No.2019-204). Written informed consent was obtained from each subject prior to any medical examination. Results:The serum levels of IL-9, IFN-γ, IL-4, TGF-β 1, IL-35 and IL-22 in the acute anterior uveitis group were significantly higher than those in the healthy control group, and the differences were statistically significant (all at P<0.05). There was no statistically significant difference in the concentration of IL-17 between the two groups ( U=704.500, P=0.872). The IL-9 concentration of patients with acute anterior uveitis in the mild, moderate and severe groups was 57.24 (47.47, 65.10), 71.68 (67.55, 78.91) and 114.01 (74.78, 139.30) ng/L, respectively, and the overall difference was statistically significant ( Z=8.766, P=0.012), and the IL-9 concentration of the mild group and the moderate group was significantly lower than that of the severe group (both at P<0.05). The concentration of IL-9 in the patients with acute anterior uveitis was positively correlated with the concentration of IL-17, TGF-β 1 and IL-35 ( rs=0.449, 0.517, 0.400; all at P<0.05), and no significant correlations were found between the concentration of IL-9 and the concentration of IFN-γ, IL-4 and IL-22 ( rs=0.293, 0.286, 0.316; all at P>0.05). Conclusions:IL-9 plays a role in promoting the immune inflammatory response in the occurrence and development of acute anterior uveitis, and it is closely related to Th17 and Treg cell-related cytokines (TGF-β 1, IL-35).

ABSTRACT

BACKGROUND@#Perioperative neurocognitive disorders (PND) are a series of severe complications in the perioperative and anesthetic periods with a decline in memory, execution ability, and information processing speed as the primary clinical manifestation. This study aimed to evaluate the impact of edaravone (EDA) on PND and peripheral blood C-X-C motif chemokine ligand 13 (CXCL13) levels in elderly patients with hip replacement.@*METHODS@#A total of 160 elderly patients undergoing hip arthroplasty in Affiliated Dongguan People's Hospital of Southern Medical University (from March 2016 to March 2018) were randomly and double-blindly categorized into an EDA group and a control group (CON). Group EDA was administered intravenously EDA 30 min before surgery, and group CON was administered intravenously saline. The cognitive function of the two groups was evaluated 1-day before the operation and at 1 and 12 months after surgery, and the incidence of post-operative delirium was tested on days 1, 3, and 7 after surgery using the Chinese version of the confusion assessment method. Serum CXCL13 and interleukin (IL)-6 concentrations were measured before anesthesia, during surgery (30 min after skin incision), and on days 1, 3, and 7 after surgery. The continuous variables in accordance with normal distribution were tested using the Student's t test, the continuous variables without normal distribution using the Mann-Whitney U test, and categorical variables by the χ2 test or Fisher exact test.@*RESULTS@#The incidence of post-operative delirium within 7 days after surgery was significantly higher in group CON than that in group EDA (31.3% vs. 15.0%, t = -5.6, P < 0.001). The modified telephone interview for cognitive status and activities of daily life scores were significantly higher in the group EDA than those in the group CON at 1 month (39.63 ± 4.35 vs. 33.63 ± 5.81, t = -2.13, P < 0.05 and 74.3 ± 12.6 vs. 61.2 ± 13.1, t = -1.69, P < 0.05) and 12 months (40.13 ± 5.93 vs. 34.13 ± 5.36, t = -3.37, P < 0.05 and 79.6 ± 11.7 vs. 65.6 ± 16.6, t = -2.08, P < 0.05) after surgery; and the incidence of neurocognitive dysfunction was significantly lower in the group EDA than that in the group CON (P < 0.05). Serum CXCL13 and IL-6 concentrations were significantly lower in the group EDA than those in the group CON during and after surgery (P < 0.05).@*CONCLUSION@#EDA can significantly reduce the serum concentrations of CXCL13 and IL-6 and improve the PND of patients.

ABSTRACT

OBJECTIVE: To e stablish modified aqueous two-phase extraction (ATPE) system of polyphenols from Archidendron clypearia. METHODS :Taking the polyphenol content ,extraction efficiency and partition coefficient of A. clypearia as indexes ,the solid-liquid ratio ,ethanol mass fraction and ultrasonic time of ATPE system were selected by single factor tests . The aqueous two-phase extracts from different polar parts of A. clypearia was prepared. The modifier was selected by taking polyphenol content and antioxidant activity [IC 50 of 1,1-diphenyl-2-trinitrophenylhydrazine (DPPH), 2,2′-hydrazine bis (3-ethylbenzothiazole-6-sulfonic acid ) diammonium salt (ABTS)] as indicators ,combined with the grey correlation analysis between polyphenols and antioxidant activity. The effects of modified ATPE system with different mass fraction (0-90%)of modifier on the extraction of polyphenols from A. clypearia were investigated and compared with traditional extraction technology (ultrasonic extraction and heating reflux extraction ). RESULTS :The optimal ATPE system included solid-liquid ratio of 1 ∶ 45, ethanol mass fraction of 40%,(NH4)2SO4 mass fraction of 11%,ultrasonic extraction time of 20 min,at room temperature. In 3 validation tests ,polyphenol content ,extraction efficiency and partition coefficient were (28.35±1.01)%(RSD=3.56%,n=3), (98.87±0.19)%(RSD=0.19%,n=3)and 13.25±0.71(RSD=5.39%,n=3),respectively. The modifier was ethyl acetate. When the mass fraction of ethyl acetate in the ethyl acetate-ethanol mixed solvent was 70%,there was no significant difference in the content and anti-oxidant activity of polyphenols from A. clypearia of modified ATPE (P>0.05). The yield and transfer rate of it were si gnificantly higher than those of ultrasonic extraction and heating reflux extraction (P<0.05). CONCLUSIONS :The modified ATPE system with better extraction yield and transfer rate than the traditional extraction technology is successfully established,which can extract polyphenols from A. clypearia 1048214903@qq.com in one step.

ABSTRACT

Type 1 diabetes (T1D) is an autoimmune disease that resulted from the severe destruction of the insulin-producing β cells in the pancreases of individuals with a genetic predisposition. Genome-wide studies have identified HLA and other risk genes associated with T1D susceptibility in humans. However, evidence obtained from the incomplete concordance of diabetes incidence among monozygotic twins suggests that environmental factors also play critical roles in T1D pathogenesis. Epigenetics is a rapidly growing field that serves as a bridge to link T1D risk genes and environmental exposures, thereby modulating the expression of critical genes relevant to T1D development beyond the changes of DNA sequences. Indeed, there is compelling evidence that epigenetic changes induced by environmental insults are implicated in T1D pathogenesis. Herein, we sought to summarize the recent progress in terms of epigenetic mechanisms in T1D initiation and progression, and discuss their potential as biomarkers and therapeutic targets in the T1D setting.

ABSTRACT

Objective:To study the distribution of ischemic stroke treatment with data mining technology and evaluate its clinical efficacy. Method:China National Knowledge Infrastructure Database(CNKI),China Science and Technology Reader's Digest Database(VIP),Wanfang Data,Chinese Biomedical Literature Database(Sino Med)were retrieved from January 1978 to December 2018. The clinical observation and study literatures on the treatment of ischemic stroke with the combination of traditional Chinese medicine and Western medicine were retrieved in the four databases. After standardized and hierarchical collection and processing of all syndromes,treatment methods,prescriptions and other information in the literatures,a database of syndrome elements and treatment of ischemic stroke was established. Syndrome factors and treatment methods were analyzed by scale evaluation and hierarchical classification methods. Kendall's tau-b correlation analysis,principal component analysis and other statistical methods were used to describe the correlation and distribution of syndrome factors and treatment methods of ischemic stroke. Result:The results of heterogeneity analysis showed that the included literatures were homogeneous and could be combined with subsequent statistics. A total of 450 syndromes and treatment methods were included in this study,and 1 287 single syndrome elements and 1 562 single treatment methods were obtained after unified and standardized splitting. Besides the corresponding syndrome elements and treatment methods,phlegm-dampness-invigorating Qi(-0.52) and Qi deficiency-invigorating Qi(-0.56) were also highly correlated. The study team represented the importance of syndrome and treatment elements with class Ⅰ,Ⅱ,Ⅲ from high to low. Qi deficiency,blood stasis and fire heat,phlegm,viscera excess were class Ⅰ syndrome elements;Yin deficiency,endogenous wind were class Ⅱ syndrome elements;Yin deficiency and Yang deficiency were class Ⅲ syndrome elements;Removing phlegm dampness,clearing heat,clearing the hollow viscera and extinguishing wind,promoting blood circulation to remove blood stasis,tonifying Qi were class Ⅰ treatment of ischemic stroke,and removing phlegm dampness,clearing heat,clearing the hollow viscera were more likely to appear simultaneously; and extinguishing wind,activating blood circulation and removing blood stasis,and benefiting Qi were more likely to appear simultaneously. Nourishing Yin and regulating Qi were class Ⅱ therapies of ischemic stroke,which were highly correlated and often appear simultaneously. Inducing resuscitation,tonifying Yang and dredging collaterals were class Ⅲ,Ⅳ,Ⅴ therapies. Conclusion:Qi deficiency,blood stasis,phlegm dampness,fire heat and viscera excess were the main syndromes of ischemic stroke,while Qi deficiency and blood stasis,phlegm heat and viscera excess were the main syndromes. Eliminating phlegm and dampness,clearing heat,clearing the hollow viscera,promoting blood circulation and removing blood stasis,extinguishing wind and benefiting Qi were the main therapies for the treatment of ischemic stroke. In clinical treatment for ischemic stroke,the therapies for relieving phlegm and dampness,clearing heat and relieving organs are often used in combination,and the therapies for promoting blood circulation and removing blood stasis were often used in combination with the therapies for invigorating Qi and extinguishing wind for the synergistic effect.

ABSTRACT

ObjectiveCasitas B-lineage lymphoma proto-oncogene (CBL) expression in different types of breast cancer and its role in the diagnosis and prognosis evaluation of breast cancer patients have been rarely reported. Here, we aimed to analyze the expression levels of CBL in breast cancer tissues and its difference in different molecular types, pathological types, TNM grades and clinical stages. Additionally, the role of CBL in the diagnosis and clinical prognosis evaluation in breast cancer patients was researched.MethodsData were downloaded from the USCS Xena database, and the expression of CBL genes in breast cancer tissues (1104 cases) and adjacent tissues (113 cases) were analyzed. CBL gene expression of different molecular types (triple negative, HER2+, Luminal A, Luminal B) and different pathological types (invasive ductal cancer, invasive lobular cancer, mixed tissue breast cancer, mucinous cancer, others) in breast cancer tissue samples were analyzed. It is divided into T1, T2, T3, T4, and Tx according to the tumor volume and the affected area of adjacent tissues. It is divided into N0, N1, N2, N3, and Nx according to the regional lymph node involvement. It is divided into cM0 (i+), M0, M1, Mx according to whether there is a distant transfer. According to different clinical stages, it is divided into stage I, stage II, stage III, stage IV, and others. Expression of CBL gene in different TNM grades and clinical stages of breast cancer was compared.Correlation between CBL gene expression and different TNM grades, clinical stages of breast cancer was examined. The ROC curve was used to evaluate the value of CBL in the diagnosis of breast cancer. According to the median value of gene expression 2.152, it was divided into high expression group (≥2.152) and low expression group (<2.152). Survival analysis was performed to verify whether CBL gene is associated with survival prognosis gene. The expression level of CBL protein in breast cancer tissues was further detected by immunohistochemistry.ResultsIn breast cancer tissues with different molecular types, the expression of CBL gene was highest in triple-negative breast cancer tissues (P<0.05). The expression of CBL gene in Luminal B breast cancer tissues was lower than that of Luminal A (P<0.05). The expression level of CBL gene in invasive ductal carcinoma, invasive lobular carcinoma and mucinous carcinoma tissues was lower than that in mixed tissue breast cancer (P<0.05). The expression level of CBL gene in invasive ductal carcinoma was higher than that of invasive lobular carcinoma (P<0.05). The expression of CBL gene from T1 to T3 gradually decreased (P<0.05). The expression of CBL gene in N0 was higher than that in N1 (P<0.05). The expression of CBL gene gradually decreased from stage Ⅰ to Ⅲ (P<0.05). The area under the ROC curve of CBL mRNA in breast cancer tissues for diagnosis was 0.768. The survival rate of the CBL gene high expression group was higher than low expression group (P<0.05). The CBL gene is a prognosis-related gene, and high expression of CBL is positively correlated with the good prognosis of breast cancer patients (P<0.05).ConclusionCBL is a good prognosis-related gene in breast cancer patients, and it is expected to become a new clinical diagnostic and prognostic marker for breast cancer patients.

ABSTRACT

Background and Objectives@#Preimplantation QRS-T morphology screening (TMS) is a composite tool for selecting subcutaneous implantable cardioverter defibrillator (S-ICD) candidates. However, its role in predicting the patient's response to cardiac resynchronization therapy (CRT) is uncertain. @*Methods@#A total of 55 consecutive de novo CRT candidates were enrolled between January 2016 and March 2017. Electrocardiogram (ECG) and TMS were performed before and soon after implantation. The ECG parameters were recorded, including QRS duration and morphology (such as ΔQRS_Index, QTc during biventricular pacing mode [BiV pacing QTc], and QRS/T ratio during biventricular pacing mode [BiV pacing QRS/T ratio]). TMS monitored three sensory vectors of the S-ICD. Six months after implantation, the responses to CRT were evaluated. @*Results@#Thirty-nine patients (70.9%) passed the TMS during biventricular pacing mode. At the six-month follow-up, the number of responders and super-responders was significantly higher in the passing group than in the non-passing group (responders: 31/39 [79.5%] vs.5/16 [31.3%], p<0.001; super-responders: 9/39 [23.1%] vs. 1/16 [6.3%], p=0.020). The superresponse rate was higher among patients who passed all three vectors than among those who passed 1 or 2 vectors (3 vs. 2 vectors, p=0.018; 3 vs. 1 vector, p=0.003). A smaller left atrial diameter, vectors that passed TMS during biventricular pacing mode, and larger ΔQRS_Index values were independently associated with good CRT response. @*Conclusions@#Our study demonstrated that patients on CRT who pass the TMS during biventricular pacing mode are more likely to respond and super-respond to CRT.

ABSTRACT

OBJECTIVE: To explore the relationship between adversity quotient and professional values in standardized-trained nurses. METHODS: OBJECTIVE: sampling method was adopted, 502 nurses who received standardized training from third class A hospitals were selected as research subjects. Questionnaire survey was carried out by Adversity Quotient Scale and Weis Nurses Professional Values Scale-Revised to calculate standardized scores of adversity quotient and professional values. RESULTS: The standardized scores of adversity quotient and professional values in the standardized-trained nurses were(3.2±0.4) and(3.8±0.6). The standardized scores of professional values, care provision, activism, responsibility, freedom and safety, and trust in standardized-trained nurses were positively correlated with the standardized score of adversity quotient(correlation coefficients were 0.192, 0.160, 0.179, 0.227, 0.166, P<0.01). Multiple linear regression analysis results showed that the higher the score of freedom and safety in standardized-trained nurses, the higher the level of adversity quotient(P<0.01). The level of adversity quotient of those who are satisfied with their position was higher than those who are indifferent to their position(P<0.01). CONCLUSION: The adversity quotient of standardized-trained nurses is positively correlated with their professional values. The level of adversity quotient of standardized-trained nurses can be improved by cultivating good professional values to stabilize the clinical nursing team.

ABSTRACT

Objective:To evaluate the effect of edaravone on long-term cognitive function in elderly patients undergoing hip replacement.Methods:A total of 160 patients, aged≥65 yr, undergoing elective hip replacement, were divided into 2 groups ( n=80 each) using the random sequence generated by the McLeod-modified Wichmann-Hill pseudo-random number generator: edaravone group (group E) and control group (group C). Spinal-epidural anesthesia was applied in two groups.Edaravone 60 mg (in 100 ml of normal saline, infusion rate 200 ml/h) was intravenously infused from the time point immediately after achieving the anesthesia plane until the following 30 min.Serum chemokine ligand 13 (CXCL13) and interleukin-6 (IL-6) concentrations were detected by enzyme-linked immunosorbent assay before anesthesia, during surgery (30 min after skin incision), and at postoperative days 1, 3 and 7.The Confusion Assessment Method Scale in Chinese was used to detect the postoperative delirium at postoperative days 1, 2, 3 and 7, and the Telephone Interview for Cognitive Status-Modified and ADL score were adopted to assess the cognitive function and quality of daily living, respectively, and the occurrence of cognitive impairment was recorded at 1 and 12 months after surgery. Results:Compared with group C, the total Telephone Interview for Cognitive Status-Modified score and ADL score were significantly increased, the incidence of postoperative delirium and cognitive impairment was decreased, and the serum CXCL13 and IL-6 concentrations were decreased during surgery and at each time point after surgery in group E ( P<0.05). Conclusion:Edaravone can reduce inflammatory responses and improve long-term cognitive function in elderly patients undergoing hip replacement.

ABSTRACT

OBJECTIVE:To optimize the formul ation of Polygala japonica cream,and to evaluate the quality of prepared cream. METHODS :With centrifugal stability ,heat resistance stability and viscosity as evaluation indexes ,the weight coefficient was determined by analytic hierarchy process (AHP),criteria importance through intercriteria correlation (CRITIC)method and mixed weighted AHP-CRITIC ,and the comprehensive score was calculated. The amount of octadecyl alcohol ,hexadecanol and mixed emulsifier (polysorbate 60 mixed with glycerin monostearate at the mass ratio of 2.82)in the formulation of P. japonica cream were screened by central composite design-response surface methodology. The optimized formulation was validated. P. japonica cream prepared by the optimal preparation was evaluated in terms of apperance ,particle,pH,stability and rheological characteristics. RESULTS :The weight coefficients of centrifugal stability ,heat resistance stability and viscosity were 0.428 5, 0.415 6 and 0.155 9 respectively,according to the mixed weighted AHP-CRITIC. The optimal formulations were 1.96 g of hexadecyl alcohol ,5.17 g of octadecyl alcohol ,2.48 g of mixed emulsifier ,1.83 g of polysorbate 60,0.65 g of glyceride monostearate,1 g of benzyl alcohol ,5 g of propylene glycol ,6 g of isopropyl myristate and 5 g of P. japonica extract,and then added water to 100 g. Prepared cream was a light yellow fluid paste with particle size of 0.5-2.5 μm and pH value of 6.5;the results of centrifugal test ,heat resistance test and cold resistance stability test showed that the cream had no oil-water separation or thickened paste. The prepared cream was shear-thinning non-Newtonian fluid. CONCLUSIONS :P. japonica cream is prepared successfully,which shows good apperance ,particle,acidity and stability.

ABSTRACT

Objective Recently, the incidence of breast cancer has been the highest among female malignant tumors. Therefore, potential biomarkers are urgently needed to predict and prevent breast cancer. This study was aimed to explore the expression and clinical significance of differential miRNAs and their target genes in breast cancer by establishing miRNA expression profile in breast cancer tissues. Methods From January 2015 to December 2018, a total of 137 cases of breast cancer tissues with paired paracancerous tissues and 20 cases of breast fibroadenoma tissues were collected from the department of breast surgery, affiliated hospital of Guizhou Medical University. The tissues were divided into breast cancer group, paracancerous group, breast fibroadenoma group and lymph node metastasis group. High-throughput sequencing technique was used to detect the miRNAs in breast cancer tissues and paired paracancerous tissues. Real-time PCR verified the expressions of the three miRNAs with the most significant expression differences in different groups. Finally, bioinformatics analysis was used to predict the target genes and investigate the expression of miRNAs and proteins of target genes in different breast diseases. Results A total of 157 upregulated and 162 downregulated miRNAs were screened by high-throughput sequencing. Mir-hsa-miR-532-3p and hsa-miR-1260b were the most significant in upregulated miRNAs while has-let-7c-5p was the most significant in downregulated miRNAs. Meanwhile, bioinformatics analysis showed that their target gene was EZH2. Compared with para-cancerous group, expressions of hsa-miR-532-3p and hsa-miR-1260b were significantly upregulated while hsa-let-7c-5p was significantly down-regulated in breast cancer group and lymph node metastasis group (all P<0.05). The miRNA expressions of target gene EZH2 in breast cancer group, breast fibroadenoma group and lymph node metastasis group (1.24±0.01, 4.02±0.01, 15.97±0.01, respectively) were upregulated when compared with the para-cancerous group (1.00±0.00), and the similar conclusion could be drawn in EZH2 protein expression. Conclusion Hsa-miR-532-3p, hsa-miR-1260b and hsa-let-7c-5p were closely related to breast cancer, which may promote the occurrence and development of breast cancer by inducing the transcriptional expression of EZH2. HsamiR-532-3p, hsa-miR-1260b, hsa-let-7c-5p and EZH2 may be potential tumor biomarkers of breast cancer.
