Efficacy of acupuncture at ghost points combined with fluoxetine in treating depression: A randomized study.

BACKGROUND: Depression affects more than 350 million people worldwide. In China, 4.2% (54 million people) of the total population suffers from depression. Psychotherapy has been shown to change cognition, improve personality, and enhance the ability to cope with difficulties and setbacks. While pharmacotherapy can reduce symptoms, it is also associated with adverse reactions and relapse after drug withdrawal. Therefore, there has been an increasing emphasis placed on the use of non-pharmacological therapies for depression. The hypothesis of this study was that acupuncture at ghost points combined with fluoxetine would be more effective than fluoxetine alone for the treatment of depression. AIM: To investigate the efficacy of acupuncture at ghost points combined with fluoxetine for the treatment of patients with depression. METHODS: This randomized controlled trial included patients with mild to moderate depression (n = 160). Patients received either acupuncture at ghost points combined with fluoxetine (n = 80) or fluoxetine alone (control group, n = 80). Needles were retained in place for 30 min, 5 times a week; three treatment cycles were administered. The Mann-Whitney U test was used to compare functional magnet resonance imaging parameters, Hamilton depression rating scale (HAMD) scores, and self-rating depression scale (SDS) scores between the acupuncture group and control group. RESULTS: There were no significant differences in HAMD or SDS scores between the acupuncture group and control group, before or after 4 wk of treatment. The acupuncture group exhibited significantly lower HAMD and SDS scores than the control group after 8 wk of treatment (P < 0.05). The acupuncture group had significantly lower fractional Amplitude of Low Frequency Fluctuations values for the left anterior wedge leaf, left posterior cingulate gyrus, left middle occipital gyrus, and left inferior occipital gyrus after 8 wk. The acupuncture group also had significantly higher values for the right inferior frontal gyrus, right insula, and right hippocampus (P < 0.05). After 8 wk of treatment, the effective rates of the acupuncture and control groups were 51.25% and 36.25%, respectively (P < 0.05). CONCLUSION: The study results suggest that acupuncture at ghost points combined with fluoxetine is more effective than fluoxetine alone for the treatment of patients with mild to moderate depression.

Effectiveness of herb-partitioned moxibustion combined with electroacupuncture on polycystic ovary syndrome in patients with symptom pattern of kidney deficiency and phlegm-dampne.

OBJECTIVE: To observe the effect of herb-partitioned moxibustion combined with electroacupuncture on polycystic ovary syndrome (PCOS) in patients with symptom pattern of kidney deficiency and phlegm-dampness. METHODS: Totally 62 PCOS patients who met the inclusion criteria were randomly divided into intervention group and control group. In the intervention group, acupoints were subjected to (43 ± 1) ℃ herb-partitioned moxibustion and electroacupuncture treatment. In the control group, acupoints were subjected to (37 ± 1) ℃ herb-partitioned moxibustion and sham electroacupuncture treatment. Treatment was provided 3 times per week for 12 weeks, and the treatment was stopped during menstruation. After the treatment, the clinical efficacy, the Traditional Chinese Medicine (TCM) symptom pattern score, basal body temperature (BBT) levels, menstrual cycle, and related sex hormone levels of the two groups were evaluated. RESULTS: Sixty patients were eventually included in the study (30 in the intervention group and 30 in the control group). There were not obvious between-group differences in the baseline efficacy parameters (all P > 0.05). (a) After treatment, the two groups have improved in terms of clinical efficacy, TCM symptom pattern score, menstrual cycle and, BBT (P < 0.01, < 0.05), and the intervention group was better than the control group (P < 0.01, < 0.05). (b) In the intervention group, the estradiol (E2) and P450 aromatase (P450arom) levels were increased (all P < 0.05), the testosterone (T) level was decreased (P < 0.05), and the luteotropic hormone (LH) and anti-Müllerian hormone (AMH) levels were significantly decreased (P < 0.01). In the control group, E2 level was increased (P < 0.05), and LH level was decreased (P < 0.05). After treatment, the T, LH, and AMH levels of the intervention group were decreased compared with those of the control group (all P < 0.05), and the P450arom level was increased (P < 0.05). CONCLUSIONS: Herb-partitioned moxibustion combined with electroacupuncture can effectively improve the related clinical symptoms of PCOS patients with kidney deficiency and phlegm-dampness. Herb-partitioned moxibustion combined with electroacupuncture may inhibit the overexpression of AMH to increase the expression level of P450arom in ovarian granulosa cells, thereby reconstructing the dependence of follicular development on FSH, and finally improving abnormal follicular development and hyperandrogenism in PCOS patients with kidney deficiency and phlegmdampness.

Herb-partitioned moxibustion regulated the miRNA expression profile in the thyroid tissues of rats with experimental autoimmune thyroiditi.

OBJECTIVE: To observe the effect of herb-partitioned moxibustion (HPM) on the miRNA expression profile of thyroid tissue in experimental autoimmune thyroiditis (EAT) rats. METHODS: Rats were randomly divided into normal control (NC) group, EAT model (EAT) group, HPM group and western medicine (Med) group. EAT model rats were prepared by a combined immunization with complete and incomplete Freund's adjuvant emulsified with porcine thyroglobulin and iodine. Rats in the HPM group were treated with HPM, while rats in the Med group were treated with levothyrocine (1 µg/2 mL) by gavage. HE staining was used to observe the pathological morphological changes of thyroid tissue, ELISAs was uaed to detect the serum concentrations of TGAb, TPOAb, FT3, FT4, TSH. We then performed high-throughput miRNA sequencing to analyse the miRNA expression profiles in the thyroid tissues, followed by a bioinformatics analysis. RT-qPCR was used to verify the identified differentially expressed miRNAs. RESULTS: HPM improved the thyroid tissue morphology and reduced serum TPOAb, TGAb, TSH concentration in EAT rats (P < 0.05), but with no obvious effect on FT3 and FT4 concentration. While the TSH, FT3 and FT4 concentration was significantly changed in the Med group (P < 0.01 or P < 0.05) compared with that of EAT group. Sequencing results showed that a total of 17 miRNAs were upregulated, and 4 were downregulated in the EAT rats, in which the expression levels of miR-346 and miR-331-5p were reversed by HPM. The target genes of the miRNAs that regulated by HPM were associated with a variety of immune factors and immune signals. RT-qPCR verification showed that the expression of miRNA-346 and miRNA-331-5p was consistent with the sequencing results. CONCLUSIONS: HPM could regulate the the expression of miRNA-346 and miRNA-331-5p, then act on their target genes to immune and inflammation-related pathways, which may be one of the mechanisms of HPM on EAT rats.

Effect of iterative reconstruction techniques on image quality in low radiation dose chest CT: a phantom study.

PURPOSE: We aimed to evaluate the quality of chest computed tomography (CT) images obtained with low-dose CT using three iterative reconstruction (IR) algorithms. METHODS: Two 64-detector spiral CT scanners (HDCT and iCT) were used to scan a chest phantom containing 6 ground-glass nodules (GGNs) at 11 radiation dose levels. CT images were reconstructed by filtered back projection or three IR algorithms. Reconstructed images were analyzed for CT values, average noise, contrast-to-noise ratio (CNR) values, subjective image noise, and diagnostic acceptability of the GGNs. Repeated-measures analysis of variance was used for statistical analyses. RESULTS: Average noise decreased and CNR increased with increasing radiation dose when the same reconstruction algorithm was applied. Average image noise was significantly lower when reconstructed with MBIR than with iDOSE4 at the same low radiation doses. The two radiologists showed good interobserver consistency in image quality with kappa 0.83. A significant relationship was found between image noise and diagnostic acceptability of the GGNs. CONCLUSION: Three IR algorithms are able to reduce the image noise and improve the image quality of low-dose CT. In the same radiation dose, the low-dose CT image quality reconstructed with MBIR algorithms is better than that of other IR algorithms.
