S-Beta-hydroxybutyric acid compositions for oral delivery are effective in rapidly raising blood ketone levels without causing acute acidosis or gastrointestinal (GI) distress when consumed in sufficiently dilute form and / or as a gel or suspension. By limiting added beta-hydroxybutyrate salts containing alkali or alkaline earth metal ions, beta-hydroxybutyric acid solutions, gels, or suspensions can deliver exogenous ketone bodies without significantly altering electrolyte balance. Although aqueous beta-hydroxybutyric acid solutions are moderately acidic with a pH of about 3.5 to 4, when diluted with sufficient water, the water acts as a pseudo buffering agent that offsets otherwise harsh acidic effects when consumed orally. Gels and suspensions can also ameliorate acidic effects by partially encapsulating the beta-hydroxybutyric acid. Beta-hydroxybutyric acid can be pure S-beta-hydroxybutyric acid or a non-racemic mixture enriched with S-beta-hydroxybutyric acid relative to R-beta-hydroxybutyric acid.

Embodiments of the present invention include methods of targeting acidosis (low pH) within the tumor microenvironment (TME) through the use of cathodic electrochemical reactions (CER). Low pH is oncogenic by supporting immunosuppression. Electrochemical reactions create local pH effects when a current passes through an electrolytic substrate such as biological tissue. Electrolysis has been used with electroporation (destabilization of the lipid bilayer via an applied electric potential) to increase cell death areas. However, the regulated increase of pH through only the cathode electrode has been ignored as a possible method to alleviate TME acidosis, which could provide substantial immunotherapeutic benefits. Here, ex vivo modeling shows that CERs can intentionally elevate pH to an anti-tumor level and that increased alkalinity promotes activation of naïve macrophages. Embodiments of the invention include pairing CER treatment protocols with existing electric field-based cancer therapies or use as a stand-alone therapy.

A traditional Chinese medicine compound for nourishing yin, clearing heat and removing blood stasis for treating primary Sjögren's syndrome combined with renal tubular acidosis and its preparation method, belonging to the field of traditional Chinese medicine compound preparations. The traditional Chinese medicine compound for nourishing yin, clearing heat and removing blood stasis is composed of Achyranthes bidentata, Rhizoma Alismatis, Radix Rehmanniae, Radix Angelicae Sinensis, Fructus Cuscutae, Fructus Rosae Laevigatae, Fructus Cuscutae, Rhizoma Gentianae, Rhizoma Phragmites, Cortex Moutan, Solanum nigrum, Astragalus, Plantago, Dendrobium, Atractylodes, Fructus Corni, Leonurus japonicus, and Licorice. This disease is a syndrome of deficiency in the root and excess in the superficial, or a mixture of deficiency and excess, with kidney yin deficiency as the root and damp-heat and blood stasis as the superficial, the two being mutually causal. Kidney yin deficiency leads to the internal generation of virtual fire, burning body fluid and causing dryness. In addition, due to the internal heat of yin deficiency, the body fluid is refined into phlegm, which accumulates in the three energizers, obstructing the qi flow, generating internal damp heat. The damp heat is long-term trapped in the kidney meridians, causing qi stagnation and blood stasis, forming a state of "dampness, heat, and blood stasis" obstruction, ultimately presenting a syndrome of deficiency in the root and excess in the superficial, or a mixture of deficiency and excess. Therefore, the present invention combines these drugs to produce a synergistic effect on the efficacy of each drug, thereby achieving the effects of nourishing yin and tonifying the kidney, clearing away heat and dampness, and promoting blood circulation and removing blood stasis.
