ABSTRACT

OBJECTIVE@#To evaluate the effects of acupuncture on hypoglycaemic outcomes in type 2 diabetes mellitus (T2DM).@*METHODS@#PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were searched from inception up to July 2020, to identify randomised controlled trials (RCTs) that enrolled patients with T2DM and compared acupuncture combined with antidiabetic drugs to antidiabetic drugs alone. The primary outcomes were haemoglobin A1c (HbA1c) and fasting blood glucose (FBG). The secondary outcomes included 2-h blood glucose (2hBG), fasting insulin (FINS), homeostatic model assessment for insulin resistance (HOMA-IR), and acupuncture-related adverse events. Mean difference (MD) and 95% confidence interval (CI) were used as the effect measure in the meta-analysis. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation tool.@*RESULTS@#Twenty-one RCTs (n=1,188) were included. The meta-analytic results showed that the acupuncture group had greater reductions in FBG (MD -6.46 mg/dL, 95% CI -11.95 to -0.98; moderate-quality evidence) and HOMA-IR (MD -1.23, 95% CI -2.16 to -0.31; low-quality evidence), but comparable changes in HbA1c (MD -0.39%, 95% CI -0.84 to 1.61; very-low-quality evidence), 2hBG (MD -4.99 mg/dL, 95% CI -20.74 to 10.76; low-quality evidence), and FINS (MD -1.32 µIU/mL, 95% CI -3.76 to 1.12; low-quality evidence). No data on the incidence of diabetic complications were found. All acupuncture-related adverse events reported were mild.@*CONCLUSIONS@#The current evidence suggests that acupuncture, as a complementary therapy to antidiabetic drugs, has a small but statistically significant effect on decreasing FBG and improving insulin resistance. The effects of acupuncture on HbA1c, 2hBG, and FINS remain uncertain. Acupuncture is generally safe in patients with mild diabetes. More evidence for the long-term effects of acupuncture on T2DM is needed. (Trial registration No. CRD42018115639).

ABSTRACT

OBJECTIVE@#To explore the expression characteristics of antigens and functional markers of natural killer (NK) cells in patients with acute myeloid leukemia (AML).@*METHODS@#Multi-parameter flow cytometry was used to detect NK cell surface markers and their functional indicators in 56 newly diagnosed AML patients and 24 healthy controls, including activating receptors NKG2D, NKP46, DNAM-1, and killing indicators granzyme B, perforin.@*RESULTS@#Referring to the WHO hematopoiesis and lymph tissue tumor classification criteria, 56 cases were roughly divided into three types: AML M1, M2, and M4/M5. However, there was no differences about NK cells among the three types, so it was no longer subdivided. NK cells were divided into two groups: CD3-CD56hiCD16- (CD56hiNK) and CD3-CD56dimCD16+ (CD56dimNK). Compared with CD56dimNK cell population, except for NKP46, the positive expression levels of NKG2D and other receptors of CD56hiNK cells in AML patients decreased (P<0.001). Compared with healthy controls, the proportion of CD56hiNK cells in AML patients increased, while the number and proportion of NK cells and proportion of CD56dimNK cells significantly decreased (P<0.05). The proportion of perforin in CD56hiNK cells significantly increased (P<0.05). The expression of DNAM-1 in CD56hiNK cells, NKG2D, DNAM-1, and perforin in CD56dimNK cells decreased significantly (P<0.05). There was no statistically significant difference in expression of other functional indexes in AML patients compared with corresponding indexes of healthy controls. In addition, the proportion of CD56hiNK cells was positively correlated with the expression of CD34+ in AML (r=0.303).@*CONCLUSION@#Compared with CD56dimNK, the ratio of CD56hiNK and the expression of functional markers in AML patients are lower. Compared with healthy controls, the number and expression ratio of NK cells in AML patients decrease and the expression of functional markers is abnormal, indicating that its function is impaired.

ABSTRACT

OBJECTIVE@#This study aimed to investigate the effects of caprylic acid (C8:0) on lipid metabolism and inflammation, and examine the mechanisms underlying these effects in mice and cells.@*METHODS@#Fifty-six 6-week-old male C57BL/6J mice were randomly allocated to four groups fed a high-fat diet (HFD) without or with 2% C8:0, palmitic acid (C16:0) or eicosapentaenoic acid (EPA). RAW246.7 cells were randomly divided into five groups: normal, lipopolysaccharide (LPS), LPS+C8:0, LPS+EPA and LPS+cAMP. The serum lipid profiles, inflammatory biomolecules, and ABCA1 and JAK2/STAT3 mRNA and protein expression were measured.@*RESULTS@#C8:0 decreased TC and LDL-C, and increased the HDL-C/LDL-C ratio after injection of LPS. Without LPS, it decreased TC in mice ( P < 0.05). Moreover, C8:0 decreased the inflammatory response after LPS treatment in both mice and cells ( P < 0.05). Mechanistic investigations in C57BL/6J mouse aortas after injection of LPS indicated that C8:0 resulted in higher ABCA1 and JAK2/STAT3 expression than that with HFD, C16:0 and EPA, and resulted in lower TNF-α, NF-κB mRNA expression than that with HFD ( P < 0.05). In RAW 264.7 cells, C8:0 resulted in lower expression of pNF-κBP65 than that in the LPS group, and higher protein expression of ABCA1, p-JAK2 and p-STAT3 than that in the LPS and LPS+cAMP groups ( P < 0.05).@*CONCLUSION@#Our studies demonstrated that C8:0 may play an important role in lipid metabolism and the inflammatory response, and the mechanism may be associated with ABCA1 and the p-JAK2/p-STAT3 signaling pathway.

ABSTRACT

Objective@#To investigate adolescent haze weather health protection behavior, and to provide scientific basis for behavioral intervention and health guidance for adolescents in haze weather.@*Methods@#From June 2015 to April 2016, 1 025 adolescents were selected from 22 classes in two middle schools of Baoding City, Hebei Province, by stratified cluster sampling method. General information questionnaire and the Brief Haze Weather Health Protection Behavior Assessment Scale Adolescent Version (BHWHPBAS AV) were used. Multiple linear regressions were conducted to explore factors affecting adolescent haze weather health protection behavior. Different models were used to confirm associations between influencing factors and BHWHPBAS AV scores.@*Results@#Adolescents had a low overall score of BHWHPBASAV (45.81±13.16). The score rate of self adjustment after haze weather was the highest (64.54%). The score rate of obtaining relevant knowledge before haze weather was the lowest (50.28%). Compared with adolescents in urban area, rural adolescents had a lower BHWHPBAS AV score ( β=-3.20, P <0.01). Compared with students (living with parents), those living without parents had a lower BHWHPBAS AV score ( β=-4.16, P =0.01). Compared with students never receive physical examination,those had received physical examination during the past years had a higher BHWHPBAS AV score ( β=4.44,5.66,9.04, P <0.01). Compared with students with no knowledge of respiratory system diseases, those with moderate to sufficient knowledge had a higher BHWHPBAS AV score ( β=9.34,12.19,P <0.01). These associations were stable and consistent.Multiple linear regression analysis showed that residence, residence with parents, physical examination and knowledge of respiratory diseases were the relevant factors of BHWHPBAS AV score ( P <0.05).@*Conclusion@#Adolescent haze weather health protection behavior level is low and is affected by many factors. Cooperation should be strengthened to conduct behavioral interventions and health guidance on haze health protection for adolescents, so as to promote healthy growth of adolescents.

ABSTRACT

BACKGROUND: Bladder cancer stem cells could promote the recurrence and drug resistance of bladder cancer. Numerous studies have shown that keratin 6B (KRT6B) is involved in the production and progression of tumors, and is closely related to the prognosis of tumors. OBJECTIVE: To observe the expression of keratin 6B in CD44+ bladder cancer stem cells and to show the influence of keratin 6B on proliferation, migration, and self-renewal of bladder cancer stem cells, and to further explore the effect of keratin 6B expression on the prognosis of bladder cancer patients. METHODS: (1) CD44+ 5637 bladder cancer stem cells were isolated by magnetic active cell sorting. Cancer stem cell-related gene expression of SOX2, OCT4, and NANOG was detected via real-time polymerase chain reaction. The spheroid formation assay was used to detect the ability of self-renewal of cancer stem cells in CD44+ cells. Keratin 6B expression was detected in CD44+ bladder cancer stem cells by real-time polymerase chain reaction. (2) The CD44+5637 bladder cancer stem cells were divided into two groups. In the keratin 6B siRNA group, keratin 6B small interfering RNA was transfected into CD44+ bladder cancer stem cells. Untransfected CD44+ bladder cancer stem cells were used as the black control group. Cells were collected at 2 days post-transfection. The proliferation, migration, and self-renewal capacity of keratin 6B siRNA CD44+ bladder cancer stem cells were detected by the colony and wound healing assay and spheroid formation respectively. (3) Totally 24 bladder cancer tissues were used by immunohistochemistry to analyze the expression of CD44v6 and keratin 6B. (4) ONCOMINE database was used to analyze the effect of keratin 6B expression on the overall survival of bladder cancer. RESULTS AND CONCLUSION: (1) Cancer stem cell-related genes (SOX2, OCT4, NANOG) and keratin 6B expression was higher in CD44+ cells isolated by magnetic active cell sorting compared with CD44- cells (P < 0.05). Cell proliferation, migration, and in vitro spheroid formation were significantly increased (P < 0.05). Keratin 6B small interfering RNA down-regulated the expression of keratin 6B in CD44+ bladder cancer stem cells (P < 0.05). (2) Compared with the blank control group, the proliferation and migration of CD44+ bladder cancer stem cells after transfection of keratin 6B small interfering RNA (P < 0.05), and the number of tumorsphere significantly diminished (P < 0.05); the expression of Notch1 and Hes1 mRNA increased (P < 0.05). (3) Keratin 6B and CD44v6 were significantly different in bladder cancer tissue (P=0.006). The overall survival rate of bladder cancer patients with high expression of keratin 6B was lower than that of patients with low expression of keratin 6B. (4) The results showed that keratin 6B was highly expressed in CD44+ bladder cancer stem cells, and could promote the proliferation, migration, and self-renewal capacity of bladder cancer stem cells. The high expression of keratin 6B contributes to improving the survival of bladder cancer patients.

ABSTRACT

Ossifying fibroma (OF) and fibrous dysplasia (FD) are two fibro-osseous lesions with overlapping clinicopathological features, making diagnosis challenging. In this study, we applied a whole-genome shallow sequencing approach to facilitate differential diagnosis via precise profiling of copy number alterations (CNAs) using minute amounts of DNA extracted from morphologically correlated microdissected tissue samples. Freshly frozen tissue specimens from OF (n = 29) and FD (n = 28) patients were obtained for analysis. Lesion fibrous tissues and surrounding normal tissues were obtained by laser capture microdissection (LCM), with ~30-50 cells (5 000-10 000 µm

ABSTRACT

Objective:To observe the effect of Qigesan on the proliferation and apoptosis of the human esophageal cancer cell EC9706, and the effect on miR-133a/protein kinase B(Akt)/mammalian target of rapamycin (mTOR) signaling pathway. Method:The effective constituent of Qigesan was extracted by ethyl acetate. Thiazolyl blue tetrazolium bromide(MTT) colorimetric assay was used to determine the dosage of Qigesan on cells and to detect the effect of Qigesan on the proliferation of EC9706 cells. The effect of Qigesan on apoptosis of EC9706 cells was detected by flow cytometry. The effect of Qigesan on miR-133a and insulin-like growth factor 1 receptor(IGF-1R) mRNA expression was detected by Real-time quantitative polymerase chain reaction (Real-time PCR) . The protein expression of Akt and mTOR in EC9706 cells was detected by Western blot. Result:Qigesan can inhibit the proliferation of EC9706 cells in a dose-dependent manner(<italic>P</italic><0.01). Inhibitory concentrations 30% inhibition concentration(IC<sub>30</sub>) 40 mg·L<sup>-1</sup> and median inhibition concentration(IC<sub>50</sub>) 80 mg·L<sup>-1</sup> were selected for follow-up experiments. Compared with the blank group, both the inhibitor group and the combination drug group can inhibit the proliferation of EC9706 cells (<italic>P</italic><0.01). The inhibitor at 0.25 μmol·L<sup>-1</sup> was selected for subsequent experiments. Compared with the blank group, Qigesan 80 mg·L<sup>-1</sup> dose group could significantly promote the late apoptosis rate and total apoptosis rate of EC9706 cells(<italic>P</italic><0.05), and the 40 mg·L<sup>-1</sup> dose group could significantly promote the late apoptosis rate of EC9706 cells(<italic>P</italic><0.05), which shows synergistic effect after concomitant use with Akt/mTOR inhibitor(<italic>P</italic><0.05). Compared with the blank control group, each group can effectively increase expression of miR-133a(<italic>P</italic><0.05). The combination of inhibitor and traditional Chinese medicine(TCM) has obvious promotion effect. Compared with blank control group, the expressions of Akt and mTOR were significantly decreased in each group(<italic>P</italic><0.05). Compared with single medication, the expressions of Akt and mTOR were decreased in combination of inhibitor and TCM group. Conclusion:Qigesan can inhibit the growth of EC9706 cells and promote apoptosis, and its inhibitory mechanism may be related to the Akt/mTOR signaling pathway by regulating the expression of miR-133a.

ABSTRACT

Objective@#Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children and adolescents. The present study investigated the cortical morphology features and their relationship with working memory (WM). @*Methods@#In the present study, a total of 36 medication naïve children with ADHD (aged from 8 to 15 years) and 36 age- and gendermatched healthy control (HC) children were included. The digit span test was used to evaluate WM. The magnetic resonance imaging (MRI) was used to examine the characteristics of cortical morphology. Firstly, we compared the cortical morphology features between two groups to identify the potential structural alterations of cortical volume, surface, thickness, and curvature in children with ADHD. Then, the correlation between the brain structural abnormalities and WM was further explored in children with ADHD. @*Results@#Compared with the HC children, the children with ADHD showed reduced cortical volumes in the left lateral superior temporal gyrus (STG) (p=6.67×10-6) and left anterior cingulate cortex (ACC) (p=3.88×10-4). In addition, the cortical volume of left lateral STG was positively correlated with WM (r=0.36, p=0.029). @*Conclusion@#Though preliminary, these findings suggest that the reduced cortical volumes of left lateral STG may contribute to the pathogenesis of ADHD and correlate with WM in children with ADHD.

ABSTRACT

Objective:To investigate the expression pattern of TCR variable region subfamily (Vβ and Vδ) in patients with mature T-cell lymphoma (TCL), and to compare the diagnostic value of TCRVβ and TCRVδ analysis in TCL.Methods:The TCRVβ flow cytometry kit was used to detect the expression of Vβ subtypes of αβT cell in 199 patients with αβ TCL and 398 patients with non-TCL, who hospitalized in Jiangsu Provincial People Hospital from 2011 to 2020. Among them, 185 cases of αβ TCL and 355 cases of non-TCL also underwent TCRβ and TCRγ gene rearrangement detection. The TCRVδ based 10-color protocol was used to detect the expression of Vδ subtypes in 24 cases of γδTCL, 10 cases of normal controls, and 15 cases with reactively higher CD4 and CD8 double-negative ratio from 2017 to 2020, and 24 cases of γδTCL and 15 cases with reactively higher CD4 and CD8 double-negative ratio underwent TCRβ, TCRγ and TCRδ gene rearrangement detection. The diagnostic performance and degree of coincidence for detecting malignant clonality were compared between TCRVβ and TCRVδ analysis and the TCR gene scanning method.Results:In the 199 cases of αβ TCL, 182 cases (91.5%) showed restricted expression or the sum of the positive percentages of the subgroups was less than 30% for the 24 TCRVβ subtypes. Among them, the subfamily members with the highest incidence of clonal T lymphocytes were TCRVβ13.2 (12.6%, 23/182) and TCRVβ3 (8.2%,15/182); the TCRVβ subtypes showed nonclonal results in 99.0% (394/398) of non-TCL. All 24 cases of γδTCL (100%) showed abnormal distribution patterns of Vδ1 and Vδ2, of which 19 cases showed restricted expression of Vδ1, and the remaining 5 cases had negative expression of either Vδ1 or Vδ2, and the positive rate of Vδ1 cells was significantly higher than that of Vδ2 cells (79.9%±10.8% vs 0.7%±0.3%, P<0.001). Among the normal control and cases with reactively higher CD4 and CD8 double-negative ratio, the positive rate of Vδ2 cells was significantly higher than that of Vδ1 cells (73.7%±6.7% vs 15.6%±4.2%, P<0.001), and all cases (25/25) showed a normal distribution pattern. In terms of the diagnostic performance of TCL, there was no significant difference of sensitivity and specificity between TCR variable region subfamily detection by flow cytometry and TCR gene scanning technology (the sensitivity was 92.4% and 91.4% respectively; the specificity was 99.0% and 95.9% respectively, P=0.065), and the coincidence rate of the two diagnostic methods is high (Kappa=0.809, P<0.001). Conclusion:Detection of TCR variable region subfamily by flow cytometry could quickly and effectively diagnose mature TCL.

Objective:To explore the differences in imaging characteristics and risk factors for mortality between the young and middle-aged and elderly patients with aortic dissection.Methods:The data from 1 220 patients with aortic dissection from January 2007 to December 2015 were successively collected. They were divided into young and middle-aged and elderly groups according to their ages. The basic information, computer comography angiography and echocardiogram results, hospital admissions and surgical details were collected and compared between the two groups using single variable regression analysis.Results:The ratio of female patients in the middle-aged and elderly group (>45 years old) was significantly higher than that of the young group (≤45 years old) (24.9% vs 18.7%, P=0.014), the ratio of hypertension patients was also significantly higher than that in the young group (77.5% vs 68.1%, P<0.001). Echocardiographic parameters showed that the prevalences of left ventricular enlargement (39.9% vs 26.9%) and left ventricular dysfunction (22.3% vs 14.1%) in the young group were significantly higher than in the middle-aged and elderly group (all P<0.001). The prevalences of ascending aorta dilation [(43.04±9.12)mm vs (41.69±10.99)mm] and thrombosis (39.1% vs 28.5%) were higher ( P<0.05). Although there was no statistically significant difference in mortality within 60 days after admission between the two groups (12.0% vs 15.1%, P=0.164), univariate regression analysis showed that aortic branch involvement was the main independent risk factor for mortality in young patients. Left ventricular remodeling (left atrial enlargement, ascending aortic dilation, aortic regurgitation) and decreased heart function were the main independent risk factors for death in the elderly patients. Conclusions:The mortality rate of young and middle-aged and elderly patients with aortic dissection are comparable, but the influencing factors are different. Screening out the relevant risk factors that affect the survival rate of the two groups, and conducting targeted prevention and intervention on them areof great significance to improve the survival rate of patients.

ABSTRACT

Migraine is a neurological disorder characterized by attacks of moderate or severe headache and various neurological symptoms. Acupuncture, as a commonly used non-pharmacological therapy, has the advantage of obvious therapeutic effect and few side effects in the prevention and treatment of migraine. But the underlying mechanism of acupuncture on migraine remains unclear. Recently, advances in neuroimaging technology have helped to objectively assess the effect of acupuncture on treating migraine and offered new opportunities to explore the central mechanism of acupuncture on treating migraine. In order to better understand the current status of neuroimaging studies on the therapeutic mechanism of acupuncture on migraine and shed light on future research, this review aims to overview the neuroimaging studies in recent 10 years from two aspects: (1) Central mechanism of acupuncture on treating acute migraine attack; (2) Central mechanism of acupuncture on preventing migraine attack.
