Effect and safety of probiotics for treating urticaria: A systematic review and meta-analysis

BACKGROUND

To assess the effect and safety of probiotics for treating urticaria.

METHODS

Randomized controlled trial (RCT) papers on the probiotics treatment published before May 2019 were retrieved from various databases like PubMed, EMbase, MEDLINE (Ovid), SCI-Hub, Springer, ClinicalKey, VIP, and CNKI. The treatment plan that we include are oral administration of single probiotic, multiple probiotics, and the combination of probiotics and antihistamines. Meta-analysis of the data was performed by RevMan 5.3 software.

RESULTS

A total of nine RCT papers were included: four papers for oral administration of single probiotic, three papers for oral administration of multiple probiotics, and two papers for oral administration of a probiotic combined with antihistamines. The results of meta-analysis showed that the therapeutic effect of the probiotic group was significantly higher than the control group (placebo or antihistamines) (RR = 1.09, 95% CI: 1.03-1.16, p = 0.006). And compared with the placebo group, the therapeutic effect of single probiotic group was significantly improved (RR = 1.11, 95% CI: 1.01-1.21, p = 0.03). Regarding therapeutic effect, there was no statistically significant difference between the multiple probiotics group and placebo group (RR = 1.00, 95% CI: 0.94 ~ 1.07, p = 0.91); the therapeutic effect of single probiotic combined antihistamine group was significantly higher than the antihistamine group (RR = 1.13, 95% CI: 1.07-1.19, p < 0.0001). Regarding the incidence of adverse reactions, there was no significant difference between the probiotic group and the control group (p = 0.46).

CONCLUSION

The treatment plan of oral administration of probiotics has significant therapeutic effects on urticaria, but the therapeutic effects of the administration of multiple probiotics and the safety of probiotic therapy are still not yet obvious. Some large-scale, multi-centered RCT studies are needed in the future for clarification.

Potential therapeutic effect and methods of traditional Chinese medicine on COVID-19-induced depression: A review

COVID‐19 (coronavirus) has spread all over the world with a high infection rate. Currently, there are no targeted therapeutic drugs for COVID‐19 as well as for stress induced by COVID‐19. The unpredictable events of COVID‐19 can trigger feelings of fear, worry, or unease in people, leading to stress‐related disorders such as depression and anxiety. It has been reported that individuals, including COVID‐19 patients, medical staff, and ordinary people, are under both physical and psychological pressure, and many of them have developed depression or anxiety during this pandemic. Traditional Chinese medicine (TCM) has been widely used in treating depression with relatively better safety and efficacy and may have an important role in treating stress‐related disorders induced by COVID‐19. In this review, we collected the common TCM treatment methods including Qigong, Acupuncture, Five Elements Musical Therapy, Five Elements Emotional Therapy, and Chinese herbal medicine from the databases of PubMed and the China National Knowledge Internet to illustrate the effect of TCM on depression. The better knowledge of TCM and implementation of TCM in COVID‐19 clinics may help to effectively improve depression induced by COVID‐19, may assist people to maintain a healthy physical and mental quality, and may alleviate the current shortage of medical resources.

EFFECT OF YISHENJIANPI RECIPE ON SEMEN QUALITY AND SPERM MITOCHONDRIA IN MICE WITH OLIGOASTHENOZOOSPERMIA INDUCED BY TRIPTERYGIUM GLYCOSIDES

Background: :

Kidney tonifying - spleen strengthening method being one of the modalities for treatment of astheno-oligozoospermia is currently commonly used in the clinical setting. To investigate the mechanism of YiShenJianPi (YSJP) Recipe, used in Traditional Chinese Medicine to benefit “the kidney” and strengthen “the spleen”.

Materials and Methods:

Oligoasthenozoospermia, male BALB/c mice were randomly divided into normal control, disease model, positive control, low-dosage and high-dosage groups. Oligoasthenozoospermia was induced by tripterygium glucosides intragastric administration before treatment started. Through using computer-aided sperm analysis to test the changes in sperm quality, utilizing flow cytometry to test the percentage of sperm with normal mitochondrial transmembrane potential (JC-1 + %), utilizing X-ray microscopy to observe epididymal sperm ultra-microstructure placing special emphasis and photographing the differences in mitochondria of the flagellum region.

Results:

Compared with DM, sperm quality of the treated mice was significantly better (P<0.05, respectively). Compared with PC, the LD group had significantly better quality sperms, while the parameters in the HD group were numerically better. Compared with NC, all other groups had significantly lower percentage of sperms with normal mitochondrial membrane potential. In PC, LD and HD groups, the percentage of sperms with normal mitochondrial membrane potential was significantly higher than that of D. The 9+9+2 mitochondrial sheath structure was complete in NC but damaged in DM. In the treatment groups, this structure was fairly clear.

Conclusion:

YSJP improved semen quality with oligoasthenozoospermia by improving sperm mitochondrial membrane potential and restoring sperm mitochondrial ultrastructure.

[Effect of acupotomy lysis on hypothalamic POMC mRNA and PPE mRNA expression in rats with 3rd lumbar vertebrae transverse process syndrome]

OBJECTIVE

To observe the effect of acupotomy lysis (AL) on hypothalamic proopiomelanocortin (POMO) mRNA and preproenkephalin (PPE) mRNA expression in rats with the third lumbar vertebrae transverse process syndrome (TLVTPS) so as to study its underlying mechanism in relieving symptoms of lumbar muscle strain.

METHODS

Twenty-four SD rats were randomly divided into normal control group, model group, AL group and electroacupunture (EA) group. The TLVTPS model was established by inserting a piece of gelatin sponge into the posterior of the left 3rd lumbar vertebrae transverse process. AL and EA were applied to the left "Shenshu"(BL 23) and "Yaoyangguan" (GV 3) respectively. The POMC mRNA and PPE mRNA expression levels in the hypothalamus were detected by in situ hybridization.

RESULTS

In comparison with the normal group, the integrated optical density (IOD) values of hypothalamic POMC mRNA and PPE mRNA positive cells in the model group were increased significantly (P < 0.01); while compared with the model group, those of POMC mRNA and PPE mRNA positive cells in both left and right hypothalamus were increased further considerably in both AL and EA groups (P < 0.01). No significant differences were found between AL and EA groups in POMC mRNA and PPE mRNA expression levels (P > 0.05).

CONCLUSION

AL and EA therapies can increase the expression of POMC mRNA and PPE mRNA in hypothalamus in rats with TLVTPS, which may contribute to its effect in relieving pain in the treatment of lumbar muscle strain.

[Expression of AMPA receptors and related protein in immobilization stressed rats and effect of Xiaoyaosan]

AIM

To observe protein expression changes of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor and related regulatory protein in the hippocampus and amygdala in chronic immobilization stressed rat and Xiaoyaosan's regulatory effect.

METHODS

Rats were tied 3 h per day to establish immobilization stress condition and treatment with Xiaoyaosan. After 7 days and 21 days stress, the protein expression of AMPA receptor subunit (GluR2/3), N-ethylmaleimide sensitive factor (NSF) and protein interacting with C-kinase 1 (PICK1) in hippocampus and amygdala were detected by using Western blot techniques.

RESULTS

The expression of GluR2/3, NSF in dentate gyrus (DG) and amygdala were markedly attenuated (P < 0.05) and PICK1 in CA1 region were significantly increased (P < 0.05) in 7 d immobilization stressed rats while 7 days xiaoyaosan treatment showed an effective regulatory result to PICK1's changes. Under 21 days immobilization stressed condition, the expression of GluR2/3, NSF in CA1 region showed an increasing trend, and GluR2/3 showed a markedly increase (P < 0.01), but showed an significantly decreased trend in amygdala, Xiaoyaosan showed an effective result to such changes above (P < 0.05). The expression of PICK1 showed increasing trend in amygdala and xiaoyaosan could lower its expression (P < 0.05).

CONCLUSION

There are different trends of the expression of AMPA receptor in repeat short-term stress versus chronic immobilization stress, and in hippocampal CA1 region versus amygdala. Xiaoyaosan has better regulation effect on the expression of AMPA receptors in the condition of chronic immobilization stress than those of repeat shortterm stress.
