RESUMO

We herein describe the synthesis of a new class of axially chiral aza/boracyclophanes (BDN1, BXN1, BDB1 and BXB1) using binaphthyls as chiral building blocks and the main-group (B/N) chemistry with tunable electronic effects. All macrocycles substituted with triarylamine donors or triarylborane acceptors are strongly luminescent. These macrocycles showed two distinct meta and para π-conjugation pathways, leading to the formation of quasi figure-of-eight and square-shaped conformations. Interestingly, comparison of such structural models revealed that the former type of macrocycles BXN1 and BXB1 gave higher racemization barriers relative to the other ones. The results reported here may provide a new approach to engineer the optical stability of π-conjugated chiral macrocycles by controlling π-substitution patterns. The ring constraints induced by macrocyclization were also demonstrated to contribute to the configurational persistence as compared with the open-chain analogues p-BTT and m-BTT.

RESUMO

We herein describe the synthesis of two axially chiral systems (HBN and BBN) by the incorporation of B centers into binaphthyl derivatives (HPy and BPy). Heteroatom-doped chiral polycyclic aromatic hydrocarbons were thus formed by fusion of the azaboroles to binaphthyls with the formation of B-N dative bonds. The resulting B-N Lewis pairs that serve as attractive fluorophores enabled modulation of the chiroptical properties both in solution and in the solid state.

RESUMO

BACKGROUND: Our study aimed (1) to describe the proportion of psychological distress among Chinese outpatients at general hospitals, (2) to compare cognitive and behavioral characteristics of patients with different distress patterns, and (3) to investigate the discriminant function of the analyzed variables in indicating the affinity towards the different distress patterns. METHODS: This multicenter cross-sectional study was conducted at ten outpatient departments at Chinese general hospitals. The somatic symptom severity scale (PHQ-15), the nine-item depression scale (PHQ-9), and the seven-item anxiety scale (GAD-7) were employed to classify patients in terms of four distress patterns. RESULTS: A total of 491 patients were enrolled. Among them, the proportion of patients with high psychological distress was significantly higher within those with high somatic distress (74.5% vs. 25.5%, p < .001). Patients with psychological distress alone and mixed distress were significantly younger and with lower monthly family income, while the proportion of female patients (80.9%) was highest in the somatic distress group. Patients with mixed distress had the most negative cognitive and behavioral characteristics [highest health anxiety (5.0 ± 1.9), lowest sense of coherence (35.5 ± 10.0), the worst doctor-patient relationship from both patients' (36.0 ± 7.3) and doctors' perspectives (23.3 ± 7.0)], as well as most impaired quality of life (41.6 ± 7.4 and 31.9 ± 10.3). In addition, compared with patients with somatic distress alone, those with psychological distress alone had lower sense of coherence, worse doctor-patient relationship, and more impaired mental quality of life, but less doctor visits. Discriminant analysis showed that gender, mental quality of life, health anxiety, sense of coherence, and frequent doctor visits were significant indicators in identifying patients with different distress patterns. CONCLUSIONS: Our study found that (1) psychological distress was not rare in the Chinese general hospital outpatients, especially in those with high somatic distress; (2) patients with psychological distress alone sought less help from doctors, despite their severe psychosocial impairment; and (3) gender, health anxiety, sense of coherence, mental quality of life, and frequent doctor visits could help to identify different distress patterns.

RESUMO

Objective To explore the characteristics of illness attribution of outpatients with multiple somatic symptoms in Peking Union Medical College Hospital. Methods It was a cross-sectional study conducted from March to October,2012. A total of 150 outpatients were recruited from the departments of Gastroenterology,Traditional Chinese Medicine and Psychological Medicine by convenience sampling. Somatic symptom scale of the Patient Health Questionnaire (PHQ-15) was used to screening each patient in the waiting list. With the cut-off value of 10,patients were divided into the somatic symptom positive (SOM+) group and somatic symptom negative (SOM-) group. Sociodemographic characteristics were compared between these two groups. All the subjects completed interviews including questions about illness attribution. All the answers of illness attribution were concluded into three major groups as physical factors,situational factors and psychological factors. Results The proportion of female was significantly higher in SOM+ group than in SOM-group (69.3% vs. 53.3%;χ2=4.048,P=0.044). In SOM+ group,significantly more patients contributed their illness to psychological factors (64.0% vs. 45.0%;χ2=5.273,P=0.022). There was no significantly difference between SOM+ group and SOM-group on the phenomenon of multiple illness attribution (41.0% vs. 32.0%;χ2=1.407,P=0.236). However,in the Department of Gastroenterology,there were significantly more outpatients in SOM+ group with multiple illness attribution (60.0% vs. 32.0%;χ2=3.945,P=0.047).Conclusions The outpatients in general hospital with multiple somatic symptoms are more likely to contribute their illness to psychological factors. The phenomenon of multiple illness attribution is common among patients. Clinicians should increase their awareness and knowledge of illness attribution,so as to provide better holistic health services.

RESUMO

OBJECTIVE: To investigate the neuroprotective etfect of puerarin on rat hippocampal neurons cultured in high glucose medium, and to examine the role of the p38 mitogen activated protein kinase (p38 MAPK) and c-Jun N-terminal kinase (JNK) signaling pathways in this effect. METHODS: Primary cultures of hippocampal neurons were prepared from newborn Sprague Dawley rats. Neuron-specific enolase immunocytochemistry was used to identify neurons. The neurons were cultured with normal medium (control group) or with high-glucose medium (high-glucose group), and puerarin (puerarin group), a p38 MAPK inhibitor (SB239063; p38 MAPK inhibitor group) or a JNK inhibitor (SP600125; JNK inhibitor group) were added. After 72 h of treatment, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay was performed to detect apoptosis, and western blotting was used to assess protein levels of p-p38, p38, p-JNK and JNK. RESULTS: In the high-glucose group, the neuronal apoptosis rate and the p-p38/p38 and p-JNK/JNK ratios were higher than in the control group. The p38 MAPK and JNK inhibitors prevented this increase in the apoptosis rate. The apoptosis rates in the puerarin group, the p38 MAPK inhibitor group and the JNK inhibitor group were significantly decreased compared with the high-glucose group. Moreover, protein levels of p-p38 and p-JNK were significantly reduced, and the p-p38/p38 and p-JNK/JNK ratios were decreased in the puerarin group compared with the high-glucose group. In addition, compared with the high-glucose group, p-p38 levels and the p-p38/p38 ratio were reduced in the p38 MAPK inhibitor group, and p-JNK levels and the p-JNK/JNK ratio were decreased in the JNK inhibitor group. CONCLUSION: Puerarin attenuates neuronal apoptosis induced by high glucose by reducing the phosphorylation of p38 and JNK.

RESUMO

The environmental transport and fate of nanoscale zero-valent iron particles (nZVI) in soil and groundwater can be altered by their hetero-aggregation with clay mineral particles (CMP). This study examines the interactions between bare or carboxymethyl cellulose (CMC)-coated nZVI with typical CMP, specifically kaolinite and montmorillonite. Methods include co-settling experiments, aggregation kinetic studies, electron microscopy, Derjaguin-Landau-Verwey-Overbeek (DLVO) and extended DLVO (EDLVO) energy analysis, and density functional theory calculations, focusing on the pH dependency of these interactions. The EDLVO theory effectively described the interactions between nZVI and CMP in aquatic environments. Under acidic conditions (pH 3.5), the interfacial interaction between bare nZVI and kaolinite is regulated by van der Waals forces, while complexation, van der Waals forces, and electrostatic attraction govern the interaction of bare nZVI with montmorillonite, primarily depositing on the SiO face. In contrast, the positively charged AlO face and edge of CMP are the main deposition sites for CMC-coated nZVI through hydrogen bonding, van der Waals forces, and electrostatic attraction. At neutral (pH 6.5) and alkaline (pH 9.5) conditions, both bare and CMC-coated nZVI predominantly attach to the AlO face and edge, facilitated by complexation or hydrogen bonding, alongside van der Waals forces. The attachment of CMC-coated nZVI to CMP surfaces shows reversible aggregation or deposition due to the steric repulsion from the CMC coating. These findings hold significant implications for the environmental applications and risk of nZVI.

RESUMO

Tu-Xian decoction (TXD), a traditional Chinese medicine (TCM) formula, has been frequently administered to manage diabetic cognitive impairment (DCI). Despite its widespread use, the mechanisms underlying TXD's protective effects on DCI have yet to be fully elucidated. As a significant regulator in neurodegenerative conditions, death-associated protein kinase-1 (DAPK-1) serves as a focus for understanding the action of TXD. This study was designed to whether TXD mediates its beneficial outcomes by inhibiting DAPK-1. To this end, a diabetic model was established using Sprague-Dawley (SD) rats through a high-fat, high-sugar (HFHS) diet regimen, followed by streptozotocin (STZ) injection. The experimental cohort was stratified into six groups: Control, Diabetic, TC-DAPK6, high-dose TXD, medium-dose TXD, and low-dose TXD groups. Following a 12-week treatment period, various assessments-including blood glucose levels, body weight measurements, Morris water maze (MWM) testing for cognitive function, brain magnetic resonance imaging (MRI), and histological analyses using hematoxylin-eosin (H&E), and Nissl staining-were conducted. Protein expression in the hippocampus was quantified through Western blotting analysis. The results revealed that TXD significantly improved spatial learning and memory abilities, and preserved hippocampal structure in diabetic rats. Importantly, TXD administration led to a down-regulation of proteins indicative of neurological damage and suppressed DAPK-1 activity within the hippocampal region. These results underscore TXD's potential in mitigating DCIvia DAPK-1 inhibition, positioning it as a viable therapeutic candidate for addressing this condition. Further investigation into TXD's molecular mechanisms may elucidate new pathways for the treatment of DCI.

RESUMO

Stable organic radicals with unique luminescence show great importance in photoelectromagnetic materials. We herein report two unusual radical-based systems (P5N-TTM and P5B-TTM) using the concerted effects of planar chiral pillar[5]arenes and tris(2,4,6-trichlorophenyl)methyl (TTM) radicals. The steric effect and electronic doublet-spin character of these radicals allowed the optical resolution and the first red emissions (∼650 nm) for pillar[5]arene derivatives. Notably, cross-coupling with macrocyclic pillar[5]arene, in turn, considerably enhanced the configurational stability of TTM radicals.

RESUMO

OBJECTIVE: To assess the efficacy and safety of mulberry twig alkaloids (Sangzhi alkaloids, SZ-A) for treatment of type 2 diabetes in a randomized, double-blind, placebo-controlled multicenter clinical trial. METHODS: A total of 200 patients were randomized to receive SZ-A (n=100) or placebo (n=100) for 16 weeks. The data analysis system for electronic data capture clinical trial central randomization system was used for randomization and dispensing of drugs. The primary outcome was the change in glycosylated hemoglobin (HbA1c) level. The secondary outcome included the proportions of cases with HbA1c <7.0% and HbA1c <6.5%, fasting blood glucose (FBG), postprandial blood glucose (PBG), area under curve for the PBG (AUC0-2h), body weight, and body mass index (BMI). Adverse events (AEs), severe adverse events (SAEs), treatment-related adverse events (TAEs), gastrointestinal disorders (GDs), blood pressure, routine blood tests, and liver and kidney function were monitored. RESULTS: Compared with baseline, the change of HbA1c at week 16 was -0.80% (95% CI: -0.98% to -0.62%) and -0.09% (95% CI: -0.27% to 0.09%) in SZ-A group and placebo group, respectively. The proportion of patients with HbA1c <7% and <6.5% was higher in the SZ-A group than in the placebo group (46.8% vs. 21.6% and 29.9% vs. 10.8%). The observed values and changes in FBG, 1 h-PBG, 2 h-PBG, and AUC0-2h differed significantly between groups (P<0.001), but differences were not significant in body weight and BMI (P>0.05). The incidence rates of AEs, TAEs, and GDs differed significantly between groups (P=0.010, P=0.005, and P=0.006, respectively), whereas the incidence rates of SAEs showed no significant differences between groups (P=1.000). CONCLUSION: SZ-A are effective and safe for treatment of type 2 diabetes. The protocol was registered in http://www.chictr.org.cn/showproj.aspx?proj=60117 (ChiCTR2000038550).

RESUMO

OBJECTIVE: To investigate the effect of quercetin, oleanolic acid, icariin and their compatibility on the apoptosis of hippocampal neurons of Sprague-Dawley (SD) rats cultured with high glucose medium and the possible mechanism. METHODS: The extracts were purchased from China Food and Drug Control Institute and Sellect. Hippocampus was obtained from newborn 24 h SD rats. After culturing the hippocampus in different medium for 72 h, flow cytometry was used to detect the apoptosis of hippocampal neurons, and Western blot was utilized to test the expressions of p-p38, p38, p-c-Jun N-terminal kinase (JNK) and JNK. RESULTS: Compared with the control group (CG), the neuronal apoptosis rate and the ratios of p-p38/p38 and p-JNK/JNK were significantly increased in the high glucose group (GG) (P < 0.01); Compared with the GG, the apoptosis rate and the ratios of p-p38/p38 and p-JNK/JNK were significantly decreased in other drug groups (P < 0.01); Compared with the monomer groups respectively, the apoptosis rate and the ratios of p-p38/p38 and p-JNK/JNK in the two-drug groups and the three-drug group all decreased (P < 0.01); Compared with the two-drug groups, the neuronal apoptosis rate and the ratio of p-JNK/JNK of the three-drug group decreased (P < 0.05). CONCLUSION: Under the condition of high glucose, the quercetin, oleanolic acid and icariin can alleviate the apoptosis of hippocampus neurons, reduce the phosphorylation of p38 and JNK in p38 mitogen-activated protein kinases and JNK signaling pathway. And the efficacy of the three drugs in combination with each other can be strengthened.

RESUMO

The AMPK/PGC-1α pathway-mediated mitochondrial dysfunction has been supposed to play a crucial role in pathogenesis of diabetic peripheral neuropathy (DPN). The present study investigated the neuroprotective potential of quercetin, a natural AMPK activator. Streptozotocin (STZ)-induced diabetic rats that developed DPN phenotype were orally administrated with quercetin (30 and 60 mg/kg per day) for 6 weeks. The morphologic changes in the sciatic nerves (SN), the pathological structure of neurons in dorsal root ganglion (DRG), and the expressions of myelin proteins were assessed. The ATP content and the mitochondrial ultrastructure were measured. Furthermore, key proteins in the AMPK/PGC-1α pathway were determined. As a result, quercetin administration at both doses improved the paw withdrawal threshold, nerve conduction velocity, and the pathologic changes in SN and DRG of DPN rats. The expressions of myelin basic protein and myelin protein zero were also increased by quercetin. The oxidative stress, decreased ATP generation, and morphological changes of mitochondria were corrected by quercetin. In vitro study found that quercetin treatment significantly decreased the high-glucose-induced generation of reactive oxygen species, as well as attenuated the mitochondrial morphologic injuries and oxidative DNA damages of RSC96 cells. Quercetin treatment promoted the expressions of phosphorylated AMPK, PGC-1α, SIRT1, NRF1, and TFAM under hyperglycemic state in vivo and in vitro. This study revealed that the neuroprotective effect of quercetin was mainly related to mitochondrial protection by activation of the AMPK/PGC-1α pathway for the first time and proved quercetin as a potential therapeutic agent in the management of diabetic neuropathy.

RESUMO

OBJECTIVE: This study aimed to evaluate the efficacy and safety of mulberry twig alkaloids (Sangzhi alkaloids [SZ-A]) in the treatment of type 2 diabetes (T2D). RESEARCH DESIGN AND METHODS: This was a multicenter, randomized, double-blind, double-dummy, and parallel controlled noninferiority clinical trial that was conducted for 24 weeks. A total of 600 patients were randomly allocated to the SZ-A group (n = 360) or acarbose group (n = 240). The primary efficacy end point was the change of glycosylated hemoglobin (HbA1c) compared with baseline. In addition, adverse events (AEs), severe AEs (SAEs), treatment-related AEs (TAEs), and gastrointestinal disorders (GDs) were monitored. RESULTS: After treatment for 24 weeks, the change in HbA1c was -0.93% (95% CI -1.03 to -0.83) (-10.2 mmol/mol [-11.3 to -9.1]) and -0.87% (-0.99 to -0.76) (-9.5 mmol/mol [-10.8 to -8.3]) in the SZ-A and acarbose groups, respectively, and the least squares mean difference was -0.05% (95% CI -0.18 to 0.07) (-0.5 mmol/mol [-2.0 to 0.8]) between the two groups, with no significant difference on the basis of covariance analysis (P > 0.05). The incidence of TAEs and GDs was significantly lower in the SZ-A group than the acarbose group (P < 0.01), but no differences for AEs or SAEs between the two groups were observed (P > 0.05). CONCLUSIONS: SZ-A exhibited equivalent hypoglycemic effects to acarbose in patients with T2D. Nevertheless, the incidence of TAEs and GDs was lower following SZ-A treatment than acarbose treatment, suggesting good safety.

RESUMO

Curcumin, a polyphenolic compound, is the active component of Curcuma longa and has been extensively investigated as an anticancer drug that modulates multiple pathways. Eukaryotic initiation factors (eIFs) have been known to play important roles in translation initiation, which controls cell growth and proliferation. Little is known about the effects of curcumin on eIFs in lung cancer. The objective of this study was to exam the curcumin cytotoxic effect and modulation of two major rate-limiting translation initiation factors, including eIF2α and eIF4E protein expression levels in lung adenocarcinoma epithelial cell line A549. Cytotoxicity was measured by MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay and protein changes were determined by Western blot. A549 cells were treated with 0-240 µM curcumin for 4-96 h. The inhibitory effects of curcumin on cytotoxicity were dose- and time-dependent (P < 0.001). The 50% inhibitory curcumin concentrations (IC50s) at 24, 48, 72, and 96 h were 93, 65, 40, and 24 µM, respectively. Protein expressions of eIF2α, eIF4E, Phospho-4E-BP1 were down-regulated, while Phospho-eIF2α and Phospho-eIF4E were up-regulated after A549 cells were treated with 20 and 40 µM curcumin for 24 h. In addition, the effects of curcumin on these protein expression changes followed a significant dose-response (P < 0.05, trend test). These findings suggest that curcumin could reduce cell viability through prohibiting the initiation of protein synthesis by modulating eIF2α and eIF4E.

RESUMO

OBJECTIVE: To observe the effects of Bushen Huoxue Formula (Formula for reinforcing the kidney and activating blood circulation) on the learning and memory function and the cerebral neurotransmitters in diabetic mice. METHODS: Forty ICR mice were randomized into the normal control group, model group, Nimotop group and Chinese medicine group, 10 mice in each group. Tail intravenous injection of alloxan was applied to prepare diabetic model. Four weeks later, intragastric administration of Bushen Huoxue Formula for the Chinese medicine group, Nimotop for the Nimotop group, and isometric distilled water for the other two groups were respectively given for 8 weeks. The changes in the blood sugar level were observed; the learning and memory function was detected by Morris labyrinth test; and the contents of norepinephrine (NE), dopamine (DA), 5-hydroxyltryptamine (5-HT) and 5-hydroxyl indole acetic acid (5-HIAA) in cerebral cortex were determined in mice of all the groups. RESULTS: The blood sugar levels in the diabetic model mice significantly increased as compared with those of the normal control group determined 72 h and 12 weeks later (P < 0.05 or P < 0.01). Latencies for Morris labyrinth test in the Nimotop group and the Chinese medicine group were significantly shortened as compared with that in the model group (P < 0.01). The contents of cortical NE in the Chinese medicine group was significantly higher than that in the model group (P < 0.01). CONCLUSION: Bushen Huoxue Formula can improve the learning and memory function in the diabetic mice, and the mechanism is possibly related with change of the cortical NE content.

RESUMO

BACKGROUND: Numerous studies suggested that chronic pain and depression were closely related and widespread in the population. When patients have symptoms of chronic pain and depression, the corresponding treatment will become difficult. Acupuncture, a unique therapeutic method of traditional Chinese medicine, has been reported to potentially serve as an alternative treatment for patients with comorbid chronic pain and depression by many research studies. METHODS: A comprehensive search was conducted through the online database, including the Cochrane Library, PubMed, EMBASE, SinoMed, CNKI, and Wanfang database. Trials were RCTs published in the English or Chinese language, recruiting participants with chronic pain and depression comorbidity. The primary outcomes were the Visual Analogue Scale (VAS) and Hamilton Depression Scale (HAMD). Statistical analyses were conducted using Review Manager 5.3. Each trail was quality appraised with the five-point Jadad Score. RESULTS: 7 eligible RCTs involving 535 patients were included. Better therapeutic effect and safety could be observed in the experimental group compared with the control group. There was a significant decrease in the VAS (mean difference (MD) = -0.68 (-1.24, -0.12), P=0.02) and HAMD (MD = -2.18 (-3.09, -1.26), P < 0.00001) scores and the incidence of adverse events between two groups. CONCLUSION: In the treatment of chronic pain with depression, acupuncture could not only get better clinical efficacy, but also have higher security compared with medicine therapy, which can be used in patients with poorer response to the conventional medication or suffering from serious side effects.

RESUMO

Objective: To investigate the association between serum adiponectin levels and diabetic peripheral neuropathy (DPN) in Chinese type 2 diabetes (T2D) patients. Design and Methods: Two hundred nineteen T2D patients aged 40-79 years were divided into two groups according to whether they had DPN. The systemic levels of five biomarkers were measured using a human adipokine multiplexed bead-based immunoassay. Diabetic peripheral neuropathy diagnostic criteria included both common DPN symptoms and neurological screening tests. Results: Most features of DPN (n=98) and non-DPN patients (n=121) are similar, but the DPN patients were slightly older, had longer diabetes duration, higher hemoglobin (Hb) A1c, lower estimated glomerular filtration rates (eGFR), less exercise, and used lipid-lowering drugs more often. Serum adiponectin levels of DPN patients were higher than that of non-DPN patients (8.13 vs. 9.63 mg/ml, P = 0.004). Serum adiponectin levels were positively associated with DPN after adjusting for age, gender, body mass index, hypertension, HbA1c, alcohol intake, smoking status, physical activity, log-transformed low density lipoprotein cholesterol, lipid-lowering drug usage, eGFR, and diabetes duration {odds ratio (OR) 1.72 [95% confidence interval (CI) 1.02-2.89], P = 0.041}. The OR refers to a doubling in biomarkers. Conclusions: Serum adiponectin levels were higher in DPN patients compared to non­DPN patients in this Chinese T2D population. Serum adiponectin levels were positively associated with DPN presence, independent of multiple confounders.

RESUMO

Lung cancer has been the leading cause of cancer death in the world. It is a health threat of human being. The clinical observations confirmed that there are some advantages by using traditional Chinese medicine (TCM) to treat lung cancer. TCM can improve symptoms and the quality of life, and extend lifespan of lung cancer patients as well. However, the specific mechanism of TCM treatment is unclear. Many scholars in the world have done a lot of research about the treatment of lung cancer with TCM. In this paper, the experimental study on treatment of lung cancer with TCM was reviewed over the past 10 years from the following aspects: inhibiting proliferation and inducing apoptosis of lung cancer cell, impact on the tumor cell matrix, inhibiting the angiogenesis and regulation the immune system. This review summarizes the research results in recent years and provides a reference for further study.

RESUMO

OBJECTIVE: To observe the effect of Ningzhi Capsule (NZC) on blood lipid spectrum in type 2 diabetes mellitus patients complicated with hyperlipemia (DM-HL). METHODS: Adopting randomized, parallel and controlled trail method, a total of 70 DM-HL patients of qi-yin deficiency and phlegm-blood stagnant syndrome type were randomized into two groups. The original medication for lowering blood sugar and blood pressure was unchanged, the trial group received oral administration of NZC 5 tablets, 3 times a day, while the control group received Lipanthgl or Simvastatin depending on their different constituents of blood lipids. After 6 months of treatment, sixty subjects completed the trail while two patients dropped out due to side effect and 8 patients lost follow-up (4 in each group). Levels of blood lipids, blood routine, liver and kidney function and symptoms in patients were detected and compared. RESULTS: After treatment, levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C), apoprotein B, and lipoprotein a (LPa) lowered, while levels of high-density lipoprotein (HDL-C) and apoprotein A raised in the trial group as compared with those before treatment (P < 0.05, P < 0.01), but showed no difference between the two groups after treatment except HDL level (P > 0.05). Scores of symptoms were also lowered significantly in the trial group (P < 0.01). In the observation period, no abnormal findings in blood and urine routine examination as well as in liver and renal function were found. CONCLUSION: NZC could lower the blood lipid spectrum and improve the TCM symptoms in DM-HL patients without any adverse reaction.

RESUMO

BACKGROUND: Diabetic cognitive impairment (DCI), a serious complication of diabetes mellitus (DM), is gaining more acceptance and attention. The learning and memory function of diabetics always decreases. Traditional Chinese medicine (TCM) has been demonstrated to be effective in treating the symptoms in China, and thereinto Chinese medicinal herbs (CMH) are the most widely used. The objective of the present study was to review and analyze the existing data about reducing the symptoms in CMH treatment for DCI. METHODS: Electronic literature databases (PubMed, EMBASE, CNKI, SinoMed, and Wan fang) were searched for randomized controlled trials conducted in China, comparing CMH with western medicines in the treatment of DCI, up to April 1, 2018. We applied standard meta-analytic techniques to analyze data from papers that reached acceptable criteria. RESULT: Nine randomized controlled trials (n = 576) on CMH were included. We found moderate evidence that CMH used alone or in combination with western medicines was more effective than western medicines alone in reliving the symptoms for DCI (total effective rate, odds radio (OR) = 4.64 (2.60, 8.29), and 95% confidence interval, P<0.00001). Besides, CMH along or in combination with western medicines showed more beneficial effects on Montreal Cognitive Assessment (MoCA) scale (mean difference (MD) = 1.31(0.75, 1.87), P<0.00001), Mini-Mental State Examination (MMSE) scale (MD = 2.07 (0.86, 3.28), P<0.00001, and TCM symptom score (TCMSS) (MD = -4.89 (-8.44, -1.34), P = 0.007). Most of the included studies showed that there was not a significant difference in the adverse events. CONCLUSIONS: These findings demonstrated that CMH used alone or in combination with western medicines were apparently better than western medicines alone in the treatment of DCI. Because of the poor quality of the studies that were available for the present meta-analysis, further researches are still needed to support these early findings.
