The Psychosomatic Traits of "People with the Five Elements in Traditional Chinese Medicine": A Qualitative Study.

Objective: To identify the representative attributes of the five elements of a person with a qualitative methodology and provide the basis for the clinical diagnosis and treatment of "people with the five elements in traditional Chinese medicine (TCM)." Methods: Data collected from the literature review, two sessions of brainstorming of experts with related experience in "people with the five elements in TCM" from October 2020 to December 2020, and six rounds of in-depth interviews with 30 participants who had various attributes of the five elements from March 2021 to October 2021 were analyzed. Triangulation was used in this study, and theming and synthesizing were used to analyze the data. Results: A total of 31 experts and 30 interviewees participated in this study. The median age of the experts and interviewees were 48.0 and 38.5 years, respectively; 51.66% and 54.8% of experts and interviewees, respectively, were men. The descriptors of facial diagrams of "people with the five elements in TCM" were complexion, shape, distribution state of facial bones, convergence trend of facial muscles, and facial expression. A theoretical model of "people with the five elements in TCM" was shaped based on these findings. Conclusion: The study suggests a possibility for bridging the gap between personality and bodily state, identifying an avenue for personality research from the perspective of TCM.

Acupuncture for metabolic syndrome: systematic review and meta-analysis.

BACKGROUND: Metabolic syndrome (MetS) is a cluster of conditions associated with an increased risk of cardiovascular disease and diabetes mellitus. Acupuncture may have benefits in the treatment of MetS. This systematic review with meta-analysis aimed to determine the effectiveness and safety of acupuncture therapy in the treatment of MetS. METHODS: Large-sample randomized controlled trials (RCTs) of acupuncture treatment for MetS were extracted from multiple Chinese and English databases and analyzed using meta-analysis to evaluate the efficacy/effectiveness of acupuncture with respect to various MetS indices in comparison with control treatments including conventional medications (CMs) and lifestyle intervention (LI), together and separately. RESULTS: A total of 13 RCTs were identified with 423 subjects undergoing acupuncture regimens and 411 receiving control interventions. Active acupuncture yielded better outcomes than sham acupuncture with respect to improving multiple MetS indices. Acupuncture monotherapy had similar effectiveness in controlling triglyceride levels and high-density lipoprotein levels compared to CMs. The overall effects of adjunctive acupuncture were markedly greater than those of controls (CMs + LI, CMs, and LI) with respect to waist circumference with a mean difference of -5.11 cm (Z = 4.57, p < 0.001) and body mass index with a mean difference of -2.54 (Z = 5.38, p <0.001), and improvements were observed in most hyperlipidemia indices and fasting blood glucose. An evidence-based acupuncture regimen was identified as a future treatment strategy for MetS. CONCLUSION: Acupuncture is beneficial in the treatment of MetS and could serve as an alternative therapy for MetS-associated conditions. Larger-scale RCTs are needed to confirm the efficacy/effectiveness of our recommended evidence-based acupuncture regimen in MetS.

Different effects of isolation-rearing and neonatal MK-801 treatment on attentional modulations of prepulse inhibition of startle in rats.

RATIONAL: Prepulse inhibition (PPI) is suppression of the startle reflex by a weaker sensory stimulus (prepulse) preceding the startling stimulus. In people with schizophrenia, impairment of attentional modulation of PPI, but not impairment of baseline PPI, is correlated with symptom severity. In rats, both fear conditioning of prepulse and perceptually spatial separation between the conditioned prepulse and a noise masker enhance PPI (the paradigms of attentional modulation of PPI). OBJECTIVES: As a neurodevelopmental model of schizophrenia, isolation rearing impairs both baseline PPI and attentional modulations of PPI in rats. This study examined in Sprague-Dawley male rats whether neonatally blocking N-methyl-D-aspartate (NMDA) receptors specifically affects attentional modulations of PPI during adulthood. RESULTS: Both socially reared rats with neonatal exposure to the NMDA receptor antagonist MK-801 and isolation-reared rats exhibited augmented startle responses, but only isolation rearing impaired baseline PPI. Fear conditioning of the prepulse enhanced PPI in socially reared rats, but MK-801-treated rats lost the prepulse feature specificity. Perceptually spatial separation between the conditioned prepulse and a noise masker further enhanced PPI only in normally reared rats. Clozapine administration during adulthood generally weakened startle, enhanced baseline PPI in neonatally interrupted rats, and restored the fear conditioning-induced PPI enhancement in isolation-reared rats with a loss of the prepulse feature specificity. Clozapine administration also abolished both the perceptual separation-induced PPI enhancement in normally reared rats and the fear conditioning-induced PPI enhancement in MK-801-treated rats. CONCLUSIONS: Isolation rearing impairs both baseline PPI and attentional modulations of PPI, but neonatally disrupting NMDA receptor-mediated transmissions specifically impair attentional modulations of PPI. Clozapine has limited alleviating effects.

Characterization of resting-state fMRI-derived functional connectivity in patients with deficiency versus excess patterns of major depression.

OBJECTIVE: Patients with major depression (MD) experience a variety of emotional and mental problems accompanied by characteristic clinical symptoms. Based on traditional Chinese medicine (TCM) notions, the clinical appearance of MD can be divided into two syndromes, namely a deficiency pattern (DP) and an excess pattern (EP), depending on the patient's clinical symptoms, pulse, and lingual signs. Brain functional neuroimaging has demonstrated cerebral activity abnormalities in MD patients. However, such abnormalities have not been linked to particular symptoms of MD. The objective of this work was to compare functional connectivity of the posterior cingulate cortex (PCC) across MD patients with DP, MD patients with EP, and normal control (NC) subjects in a resting-state functional magnetic resonance imaging (rs-fMRI) study. METHODS: Participants (24 DP patients, 21 EP patients, and 20 NCs) underwent rs-fMRI scans. Whole-brain functional connectivity of a seed in the PCC was then mapped for each subject. Functional connectivity differences among the three studied groups were analyzed statistically. RESULTS: Compared to the NC group, DP patients had decreased functional connectivity of the PCC with the right middle temporal gyrus and bilateral precuneus, as well as increased functional connectivity of the PCC with the bilateral middle frontal gyrus. Meanwhile, compared to the NC group, the EP group had decreased functional connectivity of the PCC with both the middle temporal gyrus and bilateral precuneus, as well as increased functional connectivity of the PCC with the bilateral superior frontal gyrus. Relative to the DP group, the EP group had reduced functional connectivity of the PCC with the bilateral cerebellum and left superior frontal gyrus. CONCLUSION: Functional connectivity changes differ between MD patients with different TCM syndrome types, suggesting that the TCM clinical syndromes of MD are associated with correlates in cerebral functional activity.

[Treatment of refractory depression patients of yin deficiency inner heat syndrome by jieyu granule combined paroxetine: an efficacy observation].

OBJECTIVE: To explore the efficacy of jieyu granule (JG) combined Paroxetine in treating refractory depression (RD) patients of yin deficiency inner heat syndrome (YDIHS). METHODS: Seventy RD patients of YDIHS were randomly assigned to the experimental group (JG combined Paroxetine) and the control group (Chinese medical placebo combined Paroxetine), 35 cases in each group. Hamilt Depression Rating Scale and Hamilton Anxiety Scale were used before treatment, and at the weekend of the 2nd, 4th, and 8th week, respectively. RESULTS: In the experimental group, 32 patients completed the trial and 3 patients dropped out. In the control group, 33 patients completed the trial and 2 patients dropped out. At the end of the 8th week of the treatment, the total score of Hamilt Depression Rating Scale was (14.75 +/- 7.85) in the experimental group, lower than that of the control group (19. 06 +/- 8. 31, P <0.05). At the end of the 2nd, 4th, and 8th week of the treatment, the score of Hamilton Anxiety Scale was 17.03 +/- 4.25, 14.50 +/- 5. 13, and 11.03 +/- 4.88, respectively in the experimental group, lower than that of the control group at each corresponding time point (19. 60 +/-3. 96, 17. 12 +/- 4.14, 14.64 +/- 4.47, P <0.05, P <0.01). CONCLUSION: The efficacy of JG combined Paroxetine for treating RD patients of YDIHS was superior to that of using Paroxetine alone.
