Potential Correlation Between Eczema and Hematological Malignancies Risk: A Systematic Review and Meta-Analysis.

Background: Eczema characterized by itch, sleeplessness, and adverse effects on quality of life is associated with a risk of hematological malignancies. However, there is a controversy pertaining to whether this association implies a greater or lesser risk of hematological cancers. We aimed to explore the link between eczema and hematological malignancies risk. Methods: We systematically searched PubMed and Embase databases from their inception to February 17, 2022. Two reviewers independently screened articles, extracted data and assessed study quality, respectively. The odds ratios and 95% confidence intervals (CIs) were pooled by using fixed or random-effects models. Results: 29 studies involving 2,521,574 participants examined the contribution of eczema to hematological malignancies. We found that eczema significantly increased the risk of Hodgkin's lymphoma (1.44; 95% CI, 1.07-1.95), myeloma (1.15; 95% CI, 1.04-1.28), and significantly decreased the risk of lymphocytic leukemia (0.91; 95% CI, 0.84-0.99); however, it is not significantly associated with Non-Hodgkin's lymphoma, and myelocytic leukemia. Conclusion: Eczema has been shown to be associated with the risk of hematological cancer, this association still needs to be verified in large randomized controlled trials.

LncRNA4474 inhibits renal fibrosis by regulating hepatocyte nuclear factor-1ß through miR-615 modulation.

Long noncoding RNAs (lncRNAs) and microRNAs (miRNAs) are involved in the development and progression of renal fibrosis. lncRNAs can regulate target messenger RNAs (mRNAs) by competitively binding to miRNAs. However, research on lncRNA-miRNA-mRNA interactions remains inadequate. Therefore, the aim of the present study was to investigate the possible function of lncRNA-miRNA-mRNA interactions in chronic renal fibrosis. The relationships among the expression levels of lncRNA4474, miR-615, and hepatocyte nuclear factor-1ß (HNF-1ß) mRNAs were determined through RNA sequencing. The biological roles of lncRNA4474, miR-615, and HNF-1ß in renal fibrosis were investigated with gain-of-function and loss-of-function experiments. Results showed that miR-615 expression increased in unilateral ureteral obstruction rats, accompanied by decreased lncRNA4474 and HNF-1ß mRNA expression. The overexpression of HNF-1ß attenuated the development of chronic renal fibrosis, whereas HNF-1ß knockdown promoted the development. Increase in HNF-1ß expression downregulated and upregulated the expression levels of miR-615 and lncRNA4474, respectively, thereby attenuating renal fibrosis progression. Furthermore, lncRNA4474 promoted the expression of HNF-1ß by inhibiting miR-615 expression, whereas miR-615 regulated the expression of HNF-1ß and thus activated the Wnt signaling pathway. This study demonstrated that the overexpression of lncRNA4474 may attenuate fibrosis progression, accompanied by the downregulation of miR-615 and upregulation of HNF-1ß. Hence, this study provides novel information that can be useful in the early diagnosis and treatment of renal fibrosis.

The analysis of acne increasing suicide risk.

ABSTRACT: Acne is associated with depression and anxiety; however, the relationship between acne and suicide is still unclear. This study is aimed to evaluate the association between acne and suicide by conducting a meta-analysis. Studies were identified by electronic searches of the PubMed and EMBASE databases from their inception through Jan 10, 2020. Two authors separately assessed the quality and extracted data from the selected studies. When the heterogeneity was significant, we used a random-effects model to calculate overall pooled risk estimates.Five studies involving a total of 2,276,798 participants were finally included in the meta-analysis; 52,075 participants had acne. Suicide was positively associated with acne in the overall analysis (odds ratio (OR) 1.50, 95% confidence interval (95% CI): 1.09-2.06, P = .004, I2 = 74.1%). Subgroup analyses were performed for suicidal behavior groups (P = .002, I2 = 80.4%), suicidal ideation or thoughts groups (P = .849, I2 = 0.0%), International Classification of Diseases version 9 (ICD-9) groups (P = .137, I2 = 49.6%), non-ICD-9 groups (P = .950, I2 = 0.0%), American groups (P = .311, I2 = 2.4%), and non-American groups (P = .943, I2 = 0.0%). Sensitivity analyses indicated flawed results. No publication bias was detected.Acne may significantly increase suicide risk. Clinicians should actively treat acne and consider suicide screening. Further international studies with high-quality analyses are needed as more data are published.Ethical approval and patient consent are not required because this study is a literature-based study.

Fire needle plus cupping for acute herpes zoster: study protocol for a randomized controlled trial.

BACKGROUND: Acute herpes zoster (AHZ) is a common skin disease caused by invasion of the varicella zoster virus into the ganglia and skin, and the severe pain is the most complaint, which can seriously disturb the normal life of patients. Fire needle plus cupping is a special acupuncture treatment, which is widely used to treat AHZ for its better analgesic effect in China although it has not been fully verified by rigorous randomized controlled trial (RCT). METHODS/DESIGN: To test the effect, a three-arm randomized parallel controlled trial protocol has been designed. A total of 105 AHZ patients suffering pain will be randomly divided into three groups in an equal proportion. The interventions are fire needle plus cupping (FC) in group A, famciclovir plus gabapentin (FG) in group B, and fire needle plus cupping plus famciclovir (FCF) in group C. The length for the trial is set for a week time frame. Precisely speaking, the A group (FC) is to carry out 1 treatment per day for the total of 7 treatment sessions within 1 week period. On the other hand, the B group (FG) will take drugs orally three times a day within the trial 1 week. Meanwhile, with its combination element, the C group (FCF) is due to undertake both treatments and drugs as prescribed for A and B groups within the trial week. As an intra-trial arrangement, analgesic medication will be carefully administered for temporary pain release if the sudden intolerable pain appeared. For the primary outcome, this study is due to apply visual analogue scale to identify pain intensity relief. As the secondary outcomes are concerned, this study is aiming to focus on the issues related to changes in substance P and beta-endorphin concentrations in peripheral plasma, as well as those issues of analgesic needs, side effects, symptoms, and physical signs including pain classification, local itching, burning sensation, fever, local lymphadenopathy, skin lesion area, blisters, herpes clusters, vesicular traits, ulcers, and pimples; all these are taken into account for evaluation. For the final stage, the participants are to be followed up for postherpetic neuralgia. DISCUSSION: The results of this trial aim to provide sufficient evidence on FC treatment over both FG and FCF treatments. It will then give a credible alternative treatment to cut down acute pain and to cure AHZ infection. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR1800015372 .

[Shallow Fire-needle Acupuncture Stimulation Plus Cupping Relieves Neuralgia and Down-regulates Serum Substance P Level in Patients with Acute Herpes Zoster].

OBJECTIVE: To observe the influence of repeated shallow fire-needle acupuncture stimulation plus cupping on local neuralgia and serum substance P(SP)content in patients with acute herpes zoster (AHZ). METHODS: A total of 60 cases of AHZ patients were randomly divided into control (medication) group and treatment (medication plus fire-needle) group (n＝30 in each). Patients of both groups were ordered to take Famciclovir (0.25 g/time, three times a day) and Mecobalamin (0.5 g/time, three times a day) orally for 7 days. In addition, patients of the treatment group were also treated by repeated shallow fire-needle stimulation and cupping, once a day for 7 days. Before and after the treatment, the patient's pain severity was assessed using visual analogue scale (VAS) and serum SP concentration was measured using ELISA. RESULTS: After the treatment, the VAS scores and serum SP concentrations in both groups were significantly decreased in comparison with those of their own pre-treatment (P<0.01), and were significantly lower in the treatment group than in the control group(P<0.01). There was a highly positive correlation between the decreased VAS score and serum SP content in the treatment group(P<0.01). CONCLUSION: Repeated shallow fire-needle stimulation plus cupping can accelerate the relief of local neuralgia in AHZ patients, which may be associated with its effect in down-regulating serum SP level.
