Clinical Applications of Bee Venom Acupoint Injection

Round 1

Reviewer 1 Report

Although there is an article in the Toxins magazine with similar information [Moreno et al, 2015_Three Valuable Peptides from Bee and Wasp Venoms for Therapeutic and Biotechnological Use: Melittin, Apamin and Mastoparan_Toxins 7 (4): 1126–1150], the review proposed by the authors brings more diverse and broader content about the different Clinical Applications and Pharmacological Mechanism of Bee Venom Acupoint Injection.

This reviewer believes that this review is very relevant to encourage researchers to develop biotechnological products and processes with potential for human and animal health.

This reviewer suggests that the authors indicate in the introduction of this article that, despite the clinical complications (toxicity and/or anaphylaxis) caused by multiple bee stings, bee venom and/or its isolated components have interesting pharmacological properties from a biotechnological point of view.

Bearing in mind that there are other minority components in bee venom, the ideal would be to highlight in the title of the topic "Potential Pharmacological Mechanisms of BV Components" that only the Pharmacological Mechanisms of the most abundant components of bee venom will be addressed in this topic (line 34).

#RESPONSE:

• Thank you very much for the reviewer’s comments.
• As the reviewer’s comments.
• Safety: “People concern about the safety and side effects of BVA, since this treatment may lead to sensitization and even fatal anaphylactic reactions. In some cases, after the BV treatment, patients developed acute anaphylactic shock, Guillaume-Barre syndrome or irreversible ulnar nerve injury [20]. Ahn et al. [106] reported administered BVA (0.2ml) became more redness and itching after few minutes. However, purified essential BV (0.2ml) presented less allergic than original BV. Both of these pharmacopuncture showed similar anti-inflammatory effects [106]. A study of dose toxicity test in 30 Sprague-Dawley rats treated repeatedly with SBV (0.28 mg/kg) or normal saline (0.2 mL/kg) for 4 weeks showed no significant adverse effect for BV injection after 13 weeks [11]. Comparably, a 13-week repeated research suggested that the dose of BV under approximately 0.07 mg/kg is relatively safe without observed adverse effect [10].” had been added. (Line 375-386)

Reviewer 3 Report

Comments:

1. The article should focus only on clinical applications as it is titled. The tile is not 100% right in terms of its contents. The article's title can be modified, or the summary should focus on the clinical applications and limitations of the available clinical studies. The preclinical studies data can connect the clinical observations, and then the title can be the same. It will depend on how the authors present the review.
2. The authors should separate the results from preclinical studies from the clinical studies. I found, in most cases, the information obtained from preclinical studies. The number of clinical studies is recorded less than preclinical studies, and it is expected. 
3. The list of abbreviations can be added as separated block after abstract as these are so many and often hard to remember. 
4. It is a narrative review. Figure 3 and relevant information can be deleted from the main manuscript and can be added as a supplementary document.
5. In the main text, some information may be rewritten to make it more specific. For example: Line 94 of page 3. “Because of substantial limitations of conventional therapy….”. The limitations were never mentioned in the article.
6. “3. Clinical Applications of BV Injection:” Some sections have no clinical data, but these are presented under the main caption of clinical applications. For example: “3.1.5. Intervertebral Disc Disease”, “3.1.2. Neuropathic Pain” There is no separation between the experimental and clinical studies. It will be straightforward to understand if the authors put the preclinical and clinical studies separately under each caption. 
7. The limitations and adverse events are not recorded in the manuscripts and not adequately discussed. It should be included in the article to understand the overall situation of bee venom treatment.
