ObjectiveTo investigate the regulatory effects of Ginkgolide B on the biological characteristics of brain T cells and their interactions with glial cells during the recovery phase of ischemic stroke in mice. Methods36 adult C57BL/6 mice were randomly assigned to three groups: sham-operated group (Sham group), control group (PBS group), and Ginkgolide B treatment group (GB group). The Sham group underwent only sham surgeries, whereas the PBS and GB groups were subjected to a middle cerebral artery occlusion (MCAO) model using the filament method, followed by intranasal administration of an equivalent volume of either PBS or Ginkgolide B solution for 14 days post-injury. Neurological function changes were evaluated in all three groups using the rotarod test and a neurological scoring system. On day 15, single-cell sequencing was performed on fresh tissues from the brain injury areas, surrounding cortex, corpus callosum, and striatum of mice in the PBS and GB group to assess the biological characteristics of T cells and their subpopulations, and further explore the interactions and mechanisms among T cells, microglia, and oligodendrocytes. ResultsCompared with the Sham group, both PBS and GB group exhibited significant improvements in neurological scores and reduced pre-fall motor durations (P < 0.001). Compared with the PBS group, the GB group showed a downward trend in neurological scores and an upward trend in pre-fall motor durations on days 5, 10, and 15 post-ischemic brain injury, with a significant increase in pre-fall motor duration on day 15 (P < 0.05). Compared with the PBS group, the GB group exhibited a significant increase in T cell proliferative activity in the brain 15 days post brain injury (P < 0.05). The number of proliferative T cells and the levels of lipid metabolism were significantly elevated (P < 0.05), and there was a significant increase in extracellular matrix remodeling in all T cells (P < 0.05). Additionally, the interactions between T cells and both microglia and oligodendrocytes, as well as among the microglia themselves and between microglia and oligodendrocytes, were significantly enhanced in the GB group. This was primarily evident in the strengthened interactions between CD74 and macrophage migration inhibitory factor (MIF), as well as colony stimulating factor 1 receptor (CSF1R) and colony stimulating factor 1 (CSF1) (P < 0.05). However, the inflammatory levels of T cells showed no significant differences compared with the PBS group. ConclusionA mouse model of ischemic stroke can be successfully established by MCAO operation. Ginkgolide B may promote neurological recovery post-brain injury in mice by modulating the biological characteristics of T cells within the brain and their interactions with glial cells.

Objective:To investigate the effects of ginkgolide B on neurological function recovery and the Wnt/β-catenin pathway after ischemic stroke in mice.Methods:Fifty-five C57/BL6 mice were selected, of which 10 mice were kept as the sham group and the remaining 45 mice were constructed as the ischemic stroke model. There were 40 mice who finally completed the modeling, and then they were randomly divided into the blank control group (GB0w), short-course administration group (GB1w), long-term administration group (GB2w), and long-term administration+antagonist group (GB2w+PRI-724), with 10 mice in each group. There was no drug intervention after MCAO in GB0w. The mice in GB1w were given ginkgolide B (10 mg/kg) 0.1 ml within 1 week after MCAO; in GB2w were given ginkgolide B (10 mg/kg) 0.1 ml within 2 weeks after MCAO; and in GB2w+PRI-724 were nasally fed ginkgolide B (10 mg/kg) 0.1 ml within 2 weeks after MCAO; and selective antagonist PRI-724 was given 3 h before administration of ginkgolide B on days 8 to 14. Neurological function scores, walking on rotor bar test scores, expression of transforming growth factor-β1 (TGF-β1), fibroblast growth factor 4 (FGF4), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), Wnt, β-catenin, and glycogen synthase kinase-3β (GSK-3β) were compared among the groups.Results:Compared with the sham group, the expressions of MDA, TNF-α, IL-6, FGF4, and GSK-3β in GB0w, GB1w, GB2w, and GB2w+ PRI-724 were increased, and the expressions of GSH-Px, SOD, TGF-β1, β-catenin, and Wnt were decreased (all P < 0.001). Compared with GB0w, the expressions of SOD, GSH-Px, TGF-β1, Wnt, and β-catenin were increased in GB1w, GB2w, and GB2w+PRI-724, and the expressions of MDA, TNF-α, IL-6, FGF4, and GSK-3β were decreased (all P < 0.001). Compared with GB1w, the expressions of GSH-Px, SOD, TGF-β 1, Wnt, and β-catenin were increased in GB2w and GB2w+PRI-724, and the expressions of IL-6, TNF-α, MDA, FGF4, and GSK-3β were decreased (all P < 0.001). Compared with GB2w, the neural function score, walking on the stick test score, and expressions of IL-6, TNF-α, FGF4, MDA, and GSK-3β were increased in GB2w+PRI-724, while the expressions of GSH-Px, TGF-β1, SOD, Wnt, and β-catenin were decreased (all P < 0.001). Conclusions:Ginkgolide B can effectively improve the neurological function of ischemic stroke mice and may be related to the Wnt/β-catenin pathway.

To develop a caregiver parenting behavior scale for children aged 2 to 6 years, and to verify its reliability and validity. This study recruited 1 350 caregivers of children aged 2 to 6 years. The item discrimination analysis and exploratory factor analysis were used to analyze the structure, dimensions and items of the scale. Homogeneity reliability, split-half reliability and test-retest reliability were used to analyze the reliability of the scale. Content validity and construct validity were used to analyze the validity of the scale. The results showed that the final scale contained 7 dimensions and 45 items. Cronbach's α coefficient of the total scale was 0.945; the coefficient of split half was 0.899; the test-retest reliability analysis showed that the correlation coefficients between the two tests were 0.893 (total score), 0.854 (social), 0.832 (language), 0.871 (gross motor), 0.893 (fine motor), 0.862 (cognitive), 0.832 (self-care), and 0.872 (sensory). The content validity analysis was carried out by two rounds of expert argumentation using Delphi expert consultation method. The Kendall coefficient of the items score in two rounds of Delphi expert consultation was 0.813 (P<0.01). The structure validity analysis showed that there were significant correlations between each dimension and the total scale, also between each dimension of the scale, and the extracted average variance values of each dimension was greater than the correlation coefficients between this dimension and other dimensions. In conclusion, the reliability and validity of the scale are qualified. It can be used as a tool to evaluate and guide the parenting behavior of caregivers of children aged 2 to 6 years.

Objective:To investigate whether vestibular-evoked myogenic potentials (VEMP) can be used to assess brainstem and its supplementary diagnostic value in patients with early-stage Parkinson′s disease (PD).Methods:A total of 123 patients with early-stage PD (PD group) diagnosed in the Department of Neurology of the Second Affiliated Hospital of Soochow University from January 2019 to January 2022 were consecutively enrolled, and 122 healthy controls (healthy control group) were included. Cervical VEMP (cVEMP) and ocular VEMP (oVEMP) examinations were performed on all subjects. VEMP parameters between the 2 groups were compared, and receiver operating characteristic curve was used to evaluate the auxiliary diagnostic efficacy of VEMP for early-stage PD. Correlations between VEMP parameters and motor and non-motor symptoms such as autonomic dysfunction were analyzed in the PD group using Spearman correlation analysis.Results:Bilateral latencies of cVEMP [left P1 latency (Lp13): 19.0 (16.4, 20.9) ms vs 13.1(12.0, 14.2) ms, Z=-11.18, left N1 latency (Ln23): 27.4 (24.6, 29.9) ms vs 21.2 (19.8, 23.0) ms, Z=-10.14; right P1 latency (Rp13): 18.8 (16.2, 20.9) ms vs 13.0 (11.7, 14.1) ms, Z=-10.84, right N1 latency (Rn23): 27.7 (24.3, 29.7) ms vs 21.1 (19.6, 22.9) ms, Z=-10.50] and bilateral latencies of oVEMP [left N1 latency (Ln10): 12.7 (10.7, 14.4) ms vs 10.4 (9.7, 11.4) ms, Z=-8.02, left P1 latency (Lp15): 16.5 (15.1, 18.3) ms vs 14.5 (13.4, 15.3) ms, Z=-7.96; right N1 latency (Rn10): 12.8 (11.4, 14.0) ms vs 10.5 (9.7, 11.5) ms, Z=-8.85, right P1 latency (Rp15): 16.7 (15.3, 18.3) ms vs 14.4 (13.3, 15.1) ms, Z=-9.39] of the PD group significantly prolonged compared to the healthy control group (all P<0.001). Compared to the healthy control group, the area under the curve (AUC) values of Lp13, Ln23, Rp13 and Rn23 of cVEMP in the PD group were all greater than 0.7, and the AUC values of Lp13 and Rp13 in the PD group were greater than 0.9 (all P<0.001); the AUC values of Ln10, Lp15, Rn10, and Rp15 of oVEMP in the PD group were all greater than 0.7 (all P<0.001). The Rn10-p15 corrected amplitude in PD patients was positively correlated with levodopa equivalent dose ( r=0.21, P=0.020). The Rn10 in PD patients was positively correlated with the Non-Motor Symptoms Questionnaire scores ( r=0.21, P=0.023). The Lp13-n23 corrected amplitude was negatively correlated with the Scale for Outcomes in Parkinson′s Disease-Autonomic scores ( r=-0.20, P=0.023). There was no significant correlation between VEMP parameters and Unified Parkinson′s Disease Rating Scale part Ⅲ score ( P>0.05). Conclusion:VEMP, especially cVEMP, as a non-invasive neuroelectrophysiological index, is an objective marker for brainstem damage and could be used for screening early-stage PD patients.
摘要
Liver organoids are three-dimensional cellular tissue models in which cells interact to form unique structures in culture. During the past 10 years, liver organoids with various cellular compositions, structural features, and functional properties have been described. Methods to create these advanced human cell models range from simple tissue culture techniques to complex bioengineering approaches. Liver organoid culture platforms have been used in various research fields, from modeling liver diseases to regenerative therapy. This review discusses how liver organoids are used to model disease, including hereditary liver diseases, primary liver cancer, viral hepatitis, and nonalcoholic fatty liver disease. Specifically, we focus on studies that used either of two widely adopted approaches: differentiation from pluripotent stem cells or epithelial organoids cultured from patient tissues. These approaches have enabled the generation of advanced human liver models and, more importantly, the establishment of patient-tailored models for evaluating disease phenotypes and therapeutic responses at the individual level.

Indirect immunofluorescence was used to detect 8 common respiratory pathogens, including influenza virus A (FluA), influenza virus B (FluB), parainfluenza virus (PIV), respiratory syncytial virus (RSV), adenovirus (ADV), Mycoplasma pneumoniae (MP), Chlamydia pneumoniae (CP), and Coxsackie virus group B (CoxB) IgM antibodies. χ2 test was used to analyze the results. The results showed that 1 497 of 8 710 children with ARI were positive, with a positive rate of 17.19%. The detection rate of MP among 8 common respiratory pathogens was 11.34%, accounting for 66.0%, followed by FluB, CoxB, PIV, RSV, ADV, FluA and CP, accounting for 13.83%, 9.55%, 6.01%, 2.61%, 1.47%, 0.40% and 0.13%, respectively. Respiratory tract viruses (FluA, FluB, RSV, ADV, PIV, CoxB) accounted for 33.86%.There were significant differences in the detection rates of PIV, ADV and MP among children of different genders (χ2=6.814, 5.154 and 17.784, P<0.05). The detection rate of school-age children (6-17 years old) was the highest, accounting for 33.27% (184/553). The detection rates of 8 common respiratory pathogens in patients with ARI were higher in spring and winter and lower in summer and autumn. To sum up, from 2021 to 2022, MP and FluB infection were dominant in ARI patients in our hospital. The peak period of 8 common respiratory pathogens was in spring and winter. The physical examination rate of 8 common respiratory pathogens in ARI patients aged 6-17 years old was the highest.

This cross-sectional study aimed to investigate the quality of care of diabetes in Shanghai, China. A total of 173 235 patients with type 2 diabetes in 2017 were included in the analysis. Profiles of risk factors and intermediate outcomes were determined. The patients had a mean age of 66.43 ± 8.12 (standard deviation (SD)) years and a mean diabetes duration of 7.95 ± 5.53 (SD) years. The percentage of patients who achieved the target level for HbA1c (< 7.0%) was 48.6%. Patients who achieved the target levels for blood pressure (BP) < 130/80 mmHg and low-density lipoprotein-cholesterol (LDL-c) < 2.6 mmol/L reached 17.5% and 34.0%, respectively. A total of 3.8% achieved all three target levels, and the value increased to 6.8% with an adaptation of the BP target level (< 140/90 mmHg) for those over 65 years. Multivariable analysis identified the factors associated with a great likelihood of achieving all three target levels: male, young age, short diabetes duration, low body mass index, macrovascular complications, no microvascular complications, prescribed with lipid-lowering medication, and no prescription of antihypertensive medication. In conclusion, nearly 50% and one-third of the patients with diabetes met the target levels for HbA1c and LDL-c, respectively, with a low percentage achieving the BP target level. The percentage of patients who achieved all three target levels needs significant improvement.

Objective: To evaluate the effectiveness of therapeutic massage (tuina) for treating knee osteoarthritis (KOA). Methods: Six English and Chinese databases, including Chinese National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), Cochrane Library and PubMed databases, were independently searched to identify appropriate randomized controlled trials (RCTs) studying therapeutic massage for KOA compared to oral non-steroidal anti-inflammatory drugs (NSAIDs) alone. The main outcome measures were total effectiveness and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score. Results: A total of 8 RCTs were included and they were of average quality. The results showed that therapeutic massage was more effective than NSAIDs comparing total effectiveness [risk ratio (RR)=1.14, 95％ confidence interval (CI) (1.07, 1.21), P<0.0001]; compared with NSAIDs, therapeutic massage produced more significant improvements in pain [mean difference (MD)=-2.06, 95％CI (-2.75, -1.36), P<0.00001], stiffness intensity [MD=-0.90, 95％CI (-1.05, -0.75), P<0.00001] and joint function [MD=-12.48, 95％CI (-13.91, -11.05), P<0.00001]. Conclusion: Therapeutic massage was more effective than oral NSAIDs in treating KOA. In relieving pain and stiffness and improving the function of knee joint, therapeutic massage was superior to NSAIDs.
摘要
BACKGROUND@#Little was known about the association among time in range (TIR), time above range (TAR), time below range (TBR), and cancer mortality among patients with type 2 diabetes. We aimed to investigate the association among TIR, TAR, TBR, and the risk of cancer mortality among patients with type 2 diabetes.@*METHODS@#A total of 6225 patients with type 2 diabetes were prospectively recruited in Shanghai, China. TIR was measured with continuous glucose monitoring at baseline and was defined as the average percentage of time in the target glucose range during a 24 h period. Cox proportion hazard regression analysis was used to determine the association between TIR and the risk of cancer mortality.@*RESULTS@#During a mean follow-up of 7.10 years, we confirmed 237 death events related to cancer. The multivariable-adjusted hazard ratio (HR) for cancer mortality was 1.32 (95% confidence interval [CI]: 1.01-1.75) in patients with TIR ≤70% compared with those with TIR >70%. When TIR was considered as a continuous variable, the multivariable-adjusted HR for cancer mortality associated with each 10% decrease in TIR was 1.07 (95% CI: 1.02-1.14). In the site-specific analysis, a significant association between TIR as a continuous variable and the risk of hepatocellular cancer was found (HR: 1.24; 95% CI: 1.09-1.41). However, no relationship between hemoglobin A1c and cancer mortality was observed (HR: 1.04; 95% CI: 0.97-1.10).@*CONCLUSIONS@#The present study found an inverse association of TIR with the risk of cancer mortality among patients with type 2 diabetes. New evidence of TIR was added into the clinical practice that TIR may be an optimal target of glycemic control among patients with type 2 diabetes.

AIM: To analyze the effects of salvianolic acid on autophagy and apoptosis of skeletal muscle ischemia-reperfusion injury mice through AKT/mTOR/p70S6K signaling pathway. METHODS: A total of 45 SPF male rats were randomly divided into sham operation group, model group, salvianolic acid group. Model group and salvianolic acid group were prepared for skeletal muscle ischemia-reperfusion injury model. At 72 h, 48 h, 24 h and 15 min before reperfusion, 1 mL of salvianolic acid solution was administered intraperitoneally at a dose of 30 mg/kg. Rats in the sham operation group and the model group were intraperitoneally injected with 1 mL of normal saline. The pathological morphology of the gastrocnemius muscle, the contents of serum CK and LDH, the expression of Akt, p-Akt, p70S6K, p-p70S6K, mTOR and p-mTOR in the gastrocnemius muscle and the expression of Bcl-2 and Bax in the gastrocnemius muscle were observed. RESULTS: At the 0 h, 4 h and 24 h within reperfusion, the W/D ratio of gastrocnemius muscle in the model group were higher than those in the sham operation group. The W/D ratio of the gastrocnemius muscle in the salvianolic acid group was lower than that in the model group (P<0.05). The levels of serum LDH and CK in the model group were higher than those in the sham operation group at 0 h, 4 h and 24 h after reperfusion. The serum levels of LDH and CK in the salvianolic acid group were lower than those in the model group (P<0.05). The expression of Akt protein in the gastrocnemius of the model group was lower than that in the sham operation group, and the expression of p-Akt protein was higher than that in the sham operation group. The protein expressions of Akt, p-Akt, p70S6K, p-p70S6K, mTOR and p-mTOR in the salvianolic acid group were significantly higher than those of the model group (P<0.05). The IOD value quantified the expression of Bax and Bcl-2 protein in the gastrocnemius muscle cells. The Bcl-2 IOD value and Bcl-2/Bax ratio in the model group were lower than those in the sham operation, whlie the Bax IOD value in the model group was higher than that in the sham operation group. The Bcl-2 IOD value and Bcl-2/Bax ratio in the salvianolic acid group were higher than those in the model group, and the Bax IOD value was lower than that in the model group, the difference was statistically significant (P<0.05). CONCLUSION: Salvianolic acid can maintain the homeostasis of Bax and Bcl-2 in bone cells of rats with skeletal muscle ischemia-reperfusion injury and inhibit cell apoptosis. The mechanism may be related to the activation of AKT/mTOR/p70S6K signaling pathway.
摘要
Given the increasing incidence of neurodegenerative disease (ND), recent research efforts have intensified the search for curative treatments. Despite significant research, however, existing therapeutic options for ND can only slow down the progression of the disease, but not provide a cure. Light therapy (LT) has been used to treat some mental and sleep disorders. This review illustrates recent studies of the use of LT in patients with ND and highlights its potential for clinical applications. The literature was collected from PubMed through June 2020. Selected studies were primarily English articles or articles that could be obtained with English abstracts and Chinese main text. Articles were not limited by type. Additional potential publications were also identified from the bibliographies of identified articles and the authors' reference libraries. The identified literature suggests that LT is a safe and convenient physical method of treatment. It may alleviate sleep disorders, depression, cognitive function, and other clinical symptoms. However, some studies have reported limited or no effects. Therefore, LT represents an attractive therapeutic approach for further investigation in ND. LT is an effective physical form of therapy and a new direction for research into treatments for ND. However, it requires further animal experiments to elucidate mechanisms of action and large, double-blind, randomized, and controlled trials to explore true efficacy in patients with ND.

BACKGROUND@#Many Parkinson disease (PD) patients complain about chronic fatigue and sleep disturbances during the night. The objective of this study is to determine the relationship between fatigue and sleep disturbances by using polysomnography (PSG) in PD patients.@*METHODS@#Two hundred and thirty-two PD patients (152 with mild fatigue and 80 with severe fatigue) were recruited in this study. Demographic information and clinical symptoms were collected. Fatigue severity scale (FSS) was applied to evaluate the severity of fatigue, and PSG was conducted in all PD patients. FSS ≥4 was defined as severe fatigue, and FSS <4 was defined as mild fatigue. Multivariate logistic regression and linear regression models were used to investigate the associations between fatigue and sleep disturbances.@*RESULTS@#Patients with severe fatigue tended to have a longer duration of disease, higher Unified Parkinson Disease Rating Scale score, more advanced Hoehn and Yahr stage, higher daily levodopa equivalent dose, worse depression, anxiety, and higher daytime sleepiness score. In addition, they had lower percentage of rapid eye movement (REM) sleep (P = 0.009) and were more likely to have REM sleep behavior disorder (RBD) (P = 0.018). Multivariate logistic regression analyses found that the presence of RBD and proportion of REM sleep were the independent predictors for fatigue. After the adjustment of age, sex, duration, body mass index, severity of disease, scores of Hamilton Rating Scale for Depression, Hamilton Anxiety Rating Scale, and other sleep disorders, proportion of REM sleep and degree of REM sleep without atonia in patients with PD were still associated with FSS score.@*CONCLUSION@#Considering the association between fatigue, RBD, and the altered sleep architecture, fatigue is a special subtype in PD and more studies should be focused on this debilitating symptom.

BACKGROUND@#Several recent genome-wide association studies suggested insomnia and anemia may share some common genetic components. We thus examined whether adults with anemia had higher odds of having insomnia relative to those without anemia in a cross-sectional study and a meta-analysis.@*METHODS@#Included in this cross-sectional study were 12,614 Chinese adults who participated in an ongoing cohort, the Kailuan Study. Anemia was defined as hemoglobin levels below 12.0 g/dL in women and 13.0 g/dL in men. Insomnia was assessed using the Chinese version of the Athens Insomnia Scale (AIS). A total AIS score ≥6 was considered insomnia. The association between anemia and insomnia was assessed using a logistic regression model, adjusting for potential confounders such as age, sex, chronic disease status, and plasma C-reactive protein concentrations. A meta-analysis was conducted using the fixed effects model to pool results from our study and three previously published cross-sectional studies on this topic in adult populations.@*RESULTS@#Individuals with anemia had greater odds of having insomnia (adjusted odds ratio [OR]: 1.32; 95% confidence interval [CI]: 1.03-1.70) compared with individuals without anemia. A significant association persisted after we excluded individuals with chronic inflammation, as suggested by C-reactive protein levels >1 mg/L (adjusted OR: 1.68; 95% CI: 1.22-2.32). The meta-analysis results, including 22,134 participants, also identified a positive association between anemia and insomnia (pooled OR: 1.39; 95% CI: 1.22-1.57).@*CONCLUSIONS@#The presence of anemia was significantly associated with a higher likelihood of having insomnia in adults. Due to the nature of the cross-sectional study design, results should be interpreted with caution.

Electronic health (medical) records, which are also considered as patients' information that are routinely collected, provide a great chance for researchers to develop an epidemiological understanding of disease. Electronic health records systems cannot develop without the advance of computer industries. While conducting clinical trials that are always costly, feasible and reasonable analysis of routine patients' information is more cost-effective and reflective of clinical practice, which is also called real world study. Real world studies can be well supported by big data in healthcare industry. Real world studies become more and more focused and important with the development of evidence-based medicine. These big data will definitely help in making decisions, making policies and guidelines, monitoring of effectiveness and safety on new drugs or technologies. Extracting, cleaning, and analyzing such big data will be a great challenge for clinical researchers. Successful applications and developments of electronic health record in western countries (eg, disease registries, health insurance claims, etc) have provided a clear direction for Chinese researchers. However, it is still at primary stages in China. This review tries to provide a full perspective on how to translate the electronic health records into scientific achievements, for example, among patients with diabetes. As a summary in the end, resource sharing and collaborations are highly recommended among hospitals and healthcare groups.

Background@#and Purpose The association between hemoglobin A1c (HbA1c) and stroke risk along with its subtypes is rarely reported. We aimed to investigate the association between HbA1c and the risk of incident stroke in patients with type 2 diabetes based on real world data from three healthcare systems. @*Methods@#We performed a retrospective cohort study of 27,113 African Americans and 40,431 whites with type 2 diabetes. Demographic, anthropometric, laboratory, and medication information were abstracted from the National Patient-Centered Clinical Research Network common data model. Incident stroke events including both ischemic and hemorrhagic stroke were defined. @*Results@#During a mean follow-up period of 3.79±1.68 years, 7,735 patients developed stroke (6,862 ischemic and 873 hemorrhagic). Multivariable-adjusted hazard ratios across levels of HbA1c at baseline (<6.0%, 6.0% to 6.9% [reference group], 7.0% to 7.9%, 8.0% to 8.9%, 9.0% to 9.9%, and ≥10%) were 1.07, 1.00, 1.13, 1.23, 1.27, and 1.37 (Ptrend <0.001) for total stroke, 1.02, 1.00, 1.13, 1.20, 1.24, and 1.35 (Ptrend <0.001) for ischemic stroke, and 1.40, 1.00, 1.14, 1.47, 1.47, and 1.51 (Ptrend=0.002) for hemorrhagic stroke. When we used an updated mean value of HbA1c, the U-shaped association of HbA1c with stroke risk did not change. This U-shaped association was consistent among patients of different subgroups. The U-shaped association was more pronounced among patients taking antidiabetic, lipid-lowering, and antihypertensive medications compared with those without these medications. @*Conclusions@#These data suggest that diabetes management may have to be individualized according to the guideline recommendations rather than intensively attempting to lower HbA1c.

OBJECTIVE@#To investigate the effect of a modified Wuzi Yanzong Pill (, WZYZP) on the male rats' testis after microwave radiation, as well as its potential mechanism.@*METHODS@#Forty-five male rats were randomly assigned to three groups: the control group, the radiation group, and the WZYZP group. The rats in the radiation group and WZYZP group were exposed to microwave radiation for 15 min once, while the rats in the control group were not exposed to any radiation. The rats in the WZYZP group were given a modified of WZYZP by gavage daily for 7 days. Apoptosis in the testis was evaluated using terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) assay. Histopathological alterations of the testis were observed by haematoxylin-eosin (HE) staining. Tat-interactive protein, 60kD (Tip60) and p53 expressions were determined by Western blotting.@*RESULTS@#The apoptosis index (AI) in the radiation group was higher than that of the WZYZP group and control group on day 1 (D1), day 7 (D7) day 14 (D14) after radiation (P<0.05). The seminiferous tubules were of normal morphology in the control group. In the radiation group, the partial seminiferous tubules were collapsed, basement membranes of the seminiferous epithelia became detached. WZYZP could restore the morphological changes. There was no expression of Tip60 among the three groups on D7 and D14. The expression of p53 was higher in the radiation group than in the control group (P<0.05). WZYZP could down-regulate the rising p53 induced by radiation on D7 and D14 (P<0.05).@*CONCLUSION@#A modified WZYZP may affect germ cells, and its protective effects may partly result from its ability to intervene in Tip60 mediated apoptosis.

Objective To investigate the effect of flash glucose monitoring (FGM) on ambulatory glucose profile of only oral antidiabetic drugs treated patients with type 2 diabetes mellitus. Methods Twenty-eight type 2 diabetic mellitus patients with only oral antidiabetic drugs treatment from August 2017 to January 2018 were enrolled. All the patients were exposed to FGM for 14 d without changing the original treatment and encouraged to manage self-behavior by adjusting diet and activity based on the blood glucose data obtained from the real-time scanning. The changes in glucose profile during the FGM period were observed, including estimated glycated hemoglobin (HbA1c), standard deviation of blood glucose, variable coefficient of blood glucose, mean amplitude of glycemic excursions, time in range (blood glucose 3.9 to 10.0 mmol/L), area under the curve hyperglycemia (blood glucose> 10.0 mmol/L) and area under the curve hypoglycemia (blood glucose<3.9 mmol/L). The blood glucose levels on second day and thirteenth day were used as baseline and end point respectively. Results All of the 28 patients did not change their anti-diabetic drug therapy and there were no adverse events occurred. The estimated HbA1c was significantly lower than the baseline HbA1c: (6.90 ± 1.48)% vs. (7.57 ± 1.35)%, and there was statistical difference (P = 0.004). The standard deviation of blood glucose, variable coefficient of blood glucose, mean amplitude of glycemic excursions, area under the curve hyperglycemia and area under the curve hypoglycemia at end were significantly lower than those at baseline: (2.07 ± 0.86) mmol/L vs. (2.44 ± 0.86) mmol/L, 0.26 ± 0.11 vs. 0.30 ± 0.11, (5.32 ± 2.75) mmol/L vs. (6.76 ± 3.06) mmol/L, 265 (0, 1 310) vs. 351 (107, 2 177) and 0 (0, 0) vs. 0 (0, 19), the time in range at end was significantly higher than that at baseline: (1 069 ± 386) min vs. (921 ± 449) min, and there were statistical differences (P＜0.05 or＜0.01). The rate of scanning was (12.92 ± 4.87) times/d. Conclusions FGM could be applied by type 2 diabetic mellitus patients to make self-glycemic management without changing therapy, reduce the estimated HbA1c,and hypoglycemia, and improve the glucose fluctuations, which may result from real-time scanning to find abnormal glycemia and adjust daily behavior.
