Effects of Acupuncture upon cerebral hemodynamics in cerebral small vessel disease: A pilot study.

Background and aims: Recent preclinical studies and meta-analysis of clinical trials suggested that acupuncture may improve cognition in cerebral small vessel disease (CSVD). We investigated the cerebral hemodynamics of acupuncture in subjects with CSVD and compared its impact upon the cerebral hemodynamics in normal elderly subjects. Methods: 10 subjects with CSVD (CSVD group) and 10 aged-matched control subjects who had no or insignificant CSVD (control group) were recruited. A single session of acupuncture was applied for 30 min in both groups. We assessed the effect of our acupuncture intervention on cerebral hemodynamics by transcranial Doppler ultrasound (TCD). Peak systolic velocity (PSV) and pulsatility index (PI) of the middle cerebral artery (MCA) were assessed. Results: We observed that PSV increased by a maximum of 39% at 20 min (p<0.05), while there was no significant change in PI in the CSVD group during the acupuncture session. In the control group, although we observed no significant change in PSV during the acupuncture session, there was a significant decrease in PI by a maximum of 22% at 20 min (p<0.05). No adverse events were reported during or after the procedure. Conclusion: This study suggested that our acupuncture prescription was associated with an increase in cerebral blood flow in subjects with established moderate to severe CSVD yet without apparent impact on distal vascular resistance. While, in subjects with no or insignificant CSVD, it may reduce cerebral small vessel distal vascular resistance. A larger study is needed to confirm our findings.

The regulatory roles of socio-economic status, social and intellectual activity in the relationship between alcohol consumption and cognitive decline trajectory in middle-aged and elderly Chinese: A prospective cohort study.

OBJECTIVES: To determine the relationship between alcohol consumption and cognitive decline, and to further explore the potential regulatory role of education, socio-economic status (SES), and social or intellectual activity in this relationship. METHODS: 6197 participants aged 45-75 years with four repeated measures data from 2011 to 2018 were included. A mixed-effect model was used to explore the relationship between alcohol consumption and the rate of change in cognitive decline, a latent class growth mixed model (LCGMM) was applied to determine the potential trajectory of cognitive decline, and finally, the mediating and moderating analyses were used to determine the regulatory effect of all four variables on the relationship between alcohol consumption and potential trajectory. RESULTS: Compared to never-drinkers, moderate alcohol consumption was a protective factor for overall cognitive function (ß = 0.13, 95% CI: 0.04-0.20, p < 0.001), but there was no statistical correlation with the decline rate of cognitive function. And this protective effect was no longer significant after additional adjustments for education, SES, social and intellectual activity. The LCGMM model divided participants into two trajectories, a high-level-to-decline group including 79.75% of participants (quadratic: ß [SE]: -0.90 [0.07], p < 0.001), and a low-level-to-decline group including 20.25% participants (linear: ß [SE]: -3.05 [0.49], p < 0.001). With the latter as the reference, SES played a reverse regulation role in the harmful effect of heavy drinking on cognitive trajectories (odd ratio [OR] = 0.46, 95% CI: 0.23-0.93, p < 0.05). Social and intellectual activities played a negative mediating role in the harmful effect of alcohol consumption on cognitive trajectories (light: OR = 0.96, p < 0.001; moderate: OR = 0.96, p < 0.001; heavy: OR = 0.97, p < 0.01). CONCLUSIONS: Alcohol itself has no protective effect on the decline of longitudinal cognitive trajectory. But the regulatory effect of SES, social and intellectual activities slows down the harm of alcohol consumption on the decline of cognitive function. CLINICAL TRIAL REGISTRATION: The data used in this study are from publicly available databases. They are retrospective cohort studies without any intervention. Therefore, no clinical trial registration has been conducted.

Comparing the efficacy of thyroglobulin and thyroglobulin/ thyroid-stimulating hormone ratio models in predicting a successful response to radioactive iodine therapy.

BACKGROUND: The thyroglobulin (Tg)/ thyroid-stimulating hormone (TSH) ratio has manifested to be a reliable marker for predicting prognosis in patients with differentiated thyroid carcinoma (DTC). The objective of this study was to compare the efficacy of Tg and Tg/TSH ratio models in predicting a successful response to radioactive iodine therapy. METHODS: One thousand six hundred forty-two DTC patients receiving 131I radiotherapy were finally enrolled in this retrospective study. The patients were divided into a training set (n = 973) and a validation set (n = 669) by the patient consultation time (July 2019). A receiver-operating characteristic curve was constructed for Tg and the Tg/TSH ratio to establish their cutoffs. Then, the variables were screened by univariate logistic regression and incorporated into logistic prediction models by stepwise regression, where Tg/TSH was excluded from model 1 and Tg was excluded from model 2. RESULTS: In 1642 enrolled DTC patients, the first 131I radiotherapy had an excellent response in 855 patients. The cut-offs for Tg level and Tg/TSH ratio were 3.40 ng/ mL [area under the curve (AUC): 0.789] and 36.03 ng/mIU (AUC: 0.788), respectively. In addition, the AUC of the model including Tg was higher than that of the model including Tg/TSH in both the training set (0.837 vs 0.833) and the testing set (0.854 vs 0.836). CONCLUSIONS: Both Tg and Tg/TSH ratios could be considered predictors of the effects of the first 131I ablative therapy. However, the prediction model including Tg performed better than the model including Tg/TSH.

Associations Between Abdominal Obesity Indices and Nonalcoholic Fatty Liver Disease: Chinese Visceral Adiposity Index.

Non-alcoholic fatty liver disease (NAFLD) is a common chronic liver metabolic disease worldwide. Up to 70%-80% of patients with NAFLD were obese, especially abdominal obesity. Many indicators of abdominal obesity have been reported, including waist circumference (WC), visceral obesity index (VAI), lipid accumulation (LAP), and Chinese VAI (CVAI). However, few studies investigated the associations between these indices with NAFLD. This present study aims to explore the associations between abdominal obesity indices with NAFLD. A total of 7,238 participants were involved in the cross-sectional study, and 1,584 participants were included in the longitudinal study from Jidong communities. NAFLD was assessed by abdominal ultrasonography. The trajectory of WC, VAI, LAP, and CVAI during 2013-2016 was identified by a group-based trajectory model. The logistic regression and Cox proportional hazards models analyzed the correlations and causality between abdominal obesity indices with NAFLD. In this study, the prevalence and incidence of NAFLD are approximately 44% and 26%, respectively. In the cross-sectional study, WC, VAI, LAP, and CVAI are associated with NAFLD. After adjustment for potential confounders, the moderate-rising and high-rising groups of CVAI had the highest risk of NAFLD in longitudinal analysis (hazard ratio (HR): 3.903, 95%CI: 2.434-6.259; HR: 5.694 95%CI: 3.098-10.464, respectively). Receiving operating characteristic curves show that CVAI has the best diagnostic value for NAFLD (area under the curve (AUC) = 0.868). CVAI is independently associated with the risk of NAFLD and may also have an important value to the diagnosis of NAFLD.

Burden of Thyroid Cancer From 1990 to 2019 and Projections of Incidence and Mortality Until 2039 in China: Findings From Global Burden of Disease Study.

Projecting the burden of thyroid cancer (TC) over time provides essential information to effectively plan measures for its management and prevention. This research obtained data from the Global Burden of Disease (GBD) Study from between 1990 and 2019 to model how TC will affect China until 2039 by conducting the Bayesian age-period-cohort analysis. The number of new TC cases in China was 10,030 in 1990, 39,080 in 2019, and is projected to be 47,820 in 2039. This corresponds to 3,320, 7,240, and 4,160 deaths, respectively. Disability-adjusted life years (DALYs) cases increased from 103,490 in 1990 to 187,320 in 2019. The age-standardized rate (ASR) of incidence increased from 1.01 to 2.05 during 1990-2019 and was projected to increase to 3.37 per 100,000 person-years until 2039. The ASR of mortality (ASMR) remained stable during the study period and was projected to have a mild decline from 0.39 to 0.29/100,000 during 2020-2039. Although the ASMR in male patients has maintained increasing at a rate of 2.2% per year over the past 30 years, it is expected to decline at a rate of 1.07% per year in 2019-2039. The most significant increase in crude incidence occurred in people aged 45-65 from 1990 to 2019, however, this will shift into young people aged 10-24 from 2020 to 2039. In addition, the proportion of deaths and DALYs caused by obesity increased from 1990 to 2019 and affected men more than women. In conclusion, a substantial increase in counts of incidence of TC in China is projected over the next two decades, combined with the slightly declining mortality, indicating that rational health policies are needed in the future to cope with the increasing number of TC patients, especially among males and adolescents.

Preablative Stimulated Thyroglobulin and Thyroglobulin Reduction Index as Decision-Making Markers for Second Radioactive Iodine Therapy in Patients with Structural Incomplete Response.

PURPOSE: The aim of this study was to evaluate the value of preablative stimulated thyroglobulin (presTg) and thyroglobulin reduction index (TRI) to predict the different responses to second radioactive iodine (RAI) therapy in differentiated thyroid cancer (DTC) patients with structural incomplete response (SIR). PATIENTS AND METHODS: A single-center retrospective study analyzed the different clinical outcomes after second RAI therapy in 206 patients with SIR. PresTg1 and presTg2 were measured before first and second RAI management and TRI was the reduction index of presTg1 and presTg2. Cut-off values of presTg and TRI were obtained using receiver operating characteristic analysis. The univariate logistic regression analysis was performed to confirm these parameters as prognostic factors to predict different responses to second RAI therapy. RESULTS: Only ATA risk stratification, the post-therapy whole-body scanning (Rx-WBS) findings, presTg1, presTg2, TRI, were different in patients with SIR. After second RAI therapy, 28.2% (58/206) of patients with SIR initially were reclassified as excellent response (ER). PresTg1 <6.6 ng/mL, presTg2 <1.2ng/mL, and TRI >74.2% were excellent indications to predict ER from non-ER after second RAI treatment. PresTg1 >14.9 ng/mL, presTg2 >1.8ng/mL and TRI <66.5% were well markers to predict poor outcome (SIR). High risk and distant metastases could still be considered as risk factors. CONCLUSION: DTC patients with SIR could benefit through second RAI treatment. PresTg before each RAI therapy and TRI could be considered as effective decision-making markers for second RAI therapy and as predictive indications for clinical outcomes.

Shame and Suicidal Ideation among Undergraduates in China: The Mediating Effect of Thwarted Belongingness and Perceived Burdensomeness.

Undergraduate students with shame are more likely to experience suicidal ideation, but there remains a lack of research investigating the factors underlying this relationship. The interpersonal theory of suicide posits that suicidal ideation is influenced by the simultaneous presence of thwarted belongingness and perceived burdensomeness. We examined the prevalence of suicidal ideation among undergraduate students in China and examined the association between shame and suicidal ideation mediated by perceived burdensomeness and thwarted belongingness. A survey was conducted in July 2018 involving 2320 undergraduate students, and the twelve-month prevalence of suicidal ideation was 8.95%. Shame played a crucial role in predicting suicidal ideation, and the mediating effects of perceived burdensomeness and thwarted belongingness between shame and suicidal ideation were significant. Suicidal ideation is common among undergraduate students in China and merits greater attention. Shame, perceived burdensomeness, and thwarted belongingness may be important factors to assess among undergraduate students in suicide risk assessment and psychological intervention.

Noneffectiveness of electroacupuncture for comorbid generalized anxiety disorder and irritable bowel syndrome.

BACKGROUND AND AIM: Comorbid generalized anxiety disorder and irritable bowel syndrome are common and therapeutically challenging. We aimed to assess the effectiveness of electroacupuncture in relieving anxiety and bowel symptoms in Chinese adults with this form of comorbidity. METHODS: In a single-blind randomized sham-controlled trial, subjects with comorbid generalized anxiety disorder and irritable bowel syndrome were randomly assigned to receive 10 weekly sessions of electroacupuncture or sham electroacupuncture. Patients were assessed at baseline, immediately after intervention and at 6-week follow-up. Primary outcome was anxiety (7-item Patient Health Questionnaire section for anxiety). Secondary outcomes included bowel symptoms (bowel symptoms questionnaire), depressive symptoms (9-item Patient Health Questionnaire), somatic symptoms (15-item Patient Health Questionnaire), and health-related quality of life (EuroQol-5 Dimensions). RESULTS: Eighty subjects, 40 in each arm, were randomized. All but two in the sham group completed 10 weekly sessions. There was no significant difference in the proportion of patients experiencing significant (≥ 50%) reduction of anxiety symptoms between the two groups immediately after intervention (32.4% vs 21.6%, P = 0.06) and at 6-week follow-up (25.7% in electroacupuncture vs 27% in sham, P = 0.65). Anxiety, depressive symptom, and bowel symptom severity did not differ significantly between electroacupuncture and sham groups. CONCLUSIONS: Findings failed to support the effectiveness of electroacupuncture for comorbid generalized anxiety disorder and irritable bowel syndrome. Further studies are needed to identify effective acupuncture treatment protocols for such comorbidity.

Effects of auricular stimulation in the cavum conchae on glucometabolism in patients with type 2 diabetes mellitus.

OBJECTIVE: To investigate the effect of auricular stimulation in cavum conchae on the glycemic control for patients with type 2 diabetes mellitus. METHODS: Seventy-one cases were treated with auricular electrical stimulator in the cavum choncha for 30 min, once daily for consecutive 3 months. The changes on the fasting plasma glucose (FBG), 2-h postprandial blood glucose after a 75 g oral glucose load (P2BG), glycated hemoglobin (HbA1c), blood urea nitrogen (BUN), serum creatinine (SCr), total cholesterol (TC) and aspartate transaminase (AST) were compared before and after the treatment. RESULTS: The level of the HbA1c was significantly decreased (P<0.05), and there were also statistically significant decreases in BUN, SCr, TC and AST after the treatment (P<0.05). A few patients (n=7) reduced the dose of the hypoglycemic agents in response to repeated hypoglycemia during the treatment. CONCLUSION: The stimulation in the cavum conchae of patients with types 2 diabetes mellitus may help decrease HbA1c, BUN, SCr, TC and AST, and may be an effective treatment for type 2 diabetes mellitus.

[Migraine without aura treated by comprehensive auricular acupuncture: a multicentral controlled study].

OBJECTIVE: To assess objectively the efficacy of migraine without aura treated by comprehensive auricular acupuncture. METHODS: Ninty patients of migraine without aura from three centers were selected as the observation subjects. Thirty cases from each center were treated with the comprehensive auricular acupuncture. This therapy included the retroauricular venous bleeding on the ears, the autologous blood injection at Fengchi (GB 20) and Yanglingquan (GB 34) and bleeding at the Nie (temporal), Zhen (occiput), Yidan (pancreas), Shenmen, Pizhixia (subcortex) and Neifenmi (endocrine) of auricular point. The therapy was applied once every 7-10 days. The continuous 3 treatments made one session. RESULTS: At the end of one session for the patients in three centers, the headache scores were reduced apparently as compared with those before treatment (all P< 0.05). There was no statistically significant difference in comparison among three centers (all P>0.05). The clinical total effective rates were 93.3% (28/30), 90.0% (27/30) and 93.3% (28/30) in three centers separately. There was no obvious difference in the efficacy in comparison among three centers (P>0.05). CONCLUSION: The comprehensive auricular acupuncture reduces apparently the headache score for migraine without aura and relieves the clinical symptoms of migraine. It is the simple and effective therapy for migraine without aura.

[Effects of stimulating in the cavum concha on glucometabolism in patients with diabetes].

OBJECTIVE: To explore the intervention effect of the auricular stimulator in the cavum concha for diabetes. METHODS: Forty-five cases were treated with auricular simulator in the cavum concha for 30 min, once daily for consecutive 3 months. The changes of the fasting plasma glucose (FBG), blood glucose load after 2-hour 75 g oral glucose tolerance test (P2 BG)and glycosylated hemoglobin (HbA1c) were compared before and after treatment. RESULTS: The level of the HbA1c was obviously decreased (P < 0.05, P < 0.01), and there were also statistically significant differences in FBG and P2 BG after the treatment (P < 0.05, P < 0.01). CONCLUSION: With the auricular stimulator, the stimulation in the cavum concha is benefit for the improvement of HbA1c of the diabetes.
