The conventional acupoint therapy for rheumatoid arthritis often uses traditional Chinese medicine preparations in the dosage forms of powder, ointment, and paste. However, these dosage forms have obvious drawbacks, such as low transdermal absorption, strong skin irritation, and easy detachment. Creating a traditional Chinese medicine acupoint therapy characterized by high penetration, low toxicity, low irritation, and convenient administration is of great significance. With the development of new technology for modern traditional Chinese medicine preparations, modern dosage forms such as microemulsion, microparticle, hydrogel, and liposome are combined with acupoint administration, and the derived therapeutic methods include acupoint application, acupoint injection, microneedle, and nanoporous acupuncture needle. The combination of new dosage forms of traditional Chinese medicine preparations and acupoint administration has the advantages of high drug permeability, high retention, and the formation of drug acupoint storage. The accumulation of drugs in acupoints continuously amplifies the acupoint effect, achieving a synergistic effect of drug treatment and acupoint treatment(1+1>2). This article reviews the relevant research and improvement of new dosage forms of traditional Chinese medicine preparations combined with acupoint administration for the treatment of RA, providing new development ideas for the combination of traditional Chinese medicine acupoint therapy and modern new formulation technologies.

PURPOSE: This study aimed to investigate the characteristics of poisoning drug ingested by younger children, and to compare the clinical outcome by drug forms.METHODS: This was a retrospective analysis based on medical records from the Emergency Department based Injury In-depth Surveillance (EDIIS) registry in Korea from January to December 2015. Patients aged 7 years or younger visiting the emergency department (ED) with drug poisoning were included. We classified the forms of drugs as tablets or syrup, and analyzed the characteristics by size, color, and shape. In addition, clinical outcomes and ED length of stay were compared according to the drug forms.RESULTS: A total of 308 cases were collected, and 202 patients finally were analyzed. Tablets and capsules (TACs) were more common than syrup (67.3% vs. 32.7%). Regarding clinical outcomes, patients who took TACs had higher admission rate (17.6% vs. 7.6%, P = 0.040) without a significant difference in ED length of stay compared to those who took syrups. While commonly ingested drugs in TACs were hormones, sedative and analgesics, frequent drugs in syrup were antihistamines and cold drugs. In 136 case of TACs, median long and short axes were 0.85 cm (interquartile range [IQR], 0.7–1.1 cm) and 0.72 cm (IQR, 0.59–0.82 cm), respectively. Chromatic TACs were 80 cases (58.8%) and more common than achromatic TACs. Round shapes were preferred than angular ones (96.3% vs. 3.7%).CONCLUSION: In younger children poisonings, the TACs showed higher incidence and admission rate compared to syrups. Especially, chromatic TACs and round shapes were preferred. Therefore, drugs with these characteristics need to be stored more carefully.

Nowadays antibiotic resistance is a worldwide serious problem that mainly affects public health. Omadacycline is a unique antibiotic which has two available dosage forms such as intravenous (IV) and oral that development for community-acquired bacterial infectious disease treatment. It is a modified form of older tetracycline at C-9 aminomethyl substituent of 6-member core ring of tetracycline. Modification form shows its activity against efflux pump and ribosomal protein protection mechanism of tetracycline resistance. Generally, omadacycline is effective against methicillin-resistant S. aureus (MRSA), Streptococcus pneumoniae, vancomycin-resistant Enterococcus (VRE), Legionella and Chlamydia spp. Efficacy, safety and tolerability profile of omadacycline those compares with recent antibiotics shows that omadacycline is less resistant than others. One derivative from tetracycline derivatives is 9-neopentylaminomethylminocycline called omadacycline was discovered and ongoing phase III clinical experiments as a therapy for acute bacterial skin and skin structure infections (ABSSSI) as well as community-acquired bacterial pneumonia (CABP). Omadacycline seems to be a strong drug candidate for future promising new antibacterial agent that is effective against ABSSSI and CABP.

The posaconazole tablet formulation was developed to have improved bioavailability compared to the oral suspension. Here, we compared posaconazole plasma concentration (PPC) with the posaconazole oral suspension versus the tablet in Korean patients undergoing remission induction chemotherapy for hematologic malignancies. PPC was measured at 3, 8, and 15 days of treatment with the oral suspension (174 patients) or the tablet (40 patients). At all time-points, mean PPC was significantly higher with the tablet compared to the oral suspension. Our findings suggest that posaconazole tablets generate an optimal PPC earlier and in more patients than the oral suspension among Korean patients.

OBJECTIVETo determine the effective dosage and formulation of agkistrodon in collagen-induced arthritis (CIA) rats.

METHODSCIA was induced by injection of collagen in complete/incomplete Freund's adjuvant. Agkistrodon decoction, agkistrodon powder, and agkistrodon wine were administered daily starting from the onset of arthritis. Paw swelling degree was measured by using a volume-measuring instrument every 7 days after primary immunization. Arthritis index was measured and calculated using the "five scoring method" every 7 days. The levels of serum interleukin-1ß (IL-1ß) and type II collagen IgG antibodies were detected by enzyme-linked immunosorbent assay. Finally, all ankles were removed, and X-ray radiography was performed with In-vivo Imaging System FX. Samples were counterstained with hematoxylin and eosin for analysis.

RESULTSAmong the various dosage formulations of agkistrodon, high-dose powder, which was equivalent to an amount of 6 g/day in adults, showed better effects on the inhibition of joint swelling and reduction of arthritis index score. The relatively low levels of serum IL-1 and anti-type II collagen IgG antibodies, as well as the X-ray radiography and pathology results, further proved the superiority of the high-dose powder over the other formulations. The effect of decoction on inhibiting joint swelling was inversely proportional to the dosage. Other effects, such as reduction of arthritis index score and the levels of serum IL-1 and anti-type II collagen IgG antibodies, were directly proportional to the dosage. While the use of large dose agkistrodon wine led to negative effects.

CONCLUSIONThese data highlight the potential function of high-dose agkistrodon powder, which was equivalent to an amount of 6 g/day in adults. The powder can quickly relieve the symptoms of rheumatoid arthritis and prevent aggravation of disease, especially during the early period.

Bi-yuan-ling granule (BLG) is a traditional Chinese medicine compound composed mainly of baicalin and chlorogenic acid. It has been demonstrated to be clinically effective for various inflammatory diseases such as acute rhinitis, chronic rhinitis, atrophic rhinitis and allergic rhinitis. However, the underlying mechanisms of BLG against these diseases are not fully understood. This study aimed to explore the anti-inflammatory and analgesic activities of BLG, and examine its protective effects on mouse acute lung injury (ALI). The hot plate test and acetic acid-induced writhing assay in Kunming mice were adopted to evaluate the pain-relieving effects of BLG. The anti-inflammatory activities of BLG were determined by examining the effects of BLG on xylene-caused ear swelling in Kunming mice, the cotton pellet-induced granuloma in rats, carrageenan-induced hind paw edema and lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. The results showed that BLG at 15.5 mg/g could significantly relieve the pain by 82.5% (P<0.01) at 1 h after thermal stimulation and 91.2% (P<0.01) at 2 h after thermal stimulation. BLG at doses of 7.75 and 15.5 mg/g reduced the writhing count up to 33.3% (P<0.05) and 53.4% (P<0.01), respectively. Additionally, the xylene-induced edema in mice was markedly restrained by BLG at 7.75 mg/g (P<0.05) and 15.5 mg/g (P<0.01). BLG at 5.35 and 10.7 mg/g significantly reduced paw edema by 34.8% (P<0.05) and 37.9% (P<0.05) at 5 h after carrageenan injection. The granulomatous formation of the cotton pellet was profoundly suppressed by BLG at 2.68, 5.35 and 10.7 mg/g by 15.4%, 38.2% (P<0.01) and 58.9% (P<0.001), respectively. BLG also inhibited lung W/D ratio and the release of prostaglandin E2 (PGE2) in ALI mice. In addition, the median lethal dose (LD50), median effective dose (ED50) and half maximal inhibitory concentration (IC50) of BLG were found to be 42.7, 3.2 and 12.33 mg/g, respectively. All the findings suggest that BLG has significantly anti-inflammatory and analgesic effects and it may help reduce the damage of ALI.

The borneol was included with β-CD and prepared Fufang Danshen intestinal adhesion pellets. GC method for determination of borneol in Fufang Danshen intestinal adhesion pellets was established to study its in vitro dissolution and make a comparison with the Fufang Danshen tablet, in this way, the rationality of dosage form was evaluated. The first method of dissolution determination was used for determining the in vitro dissolution of borneol in Fufang Danshen intestinal adhesion pellets in artificial intestinal juice, and Fufang Danshen tablet in artificial gastric juice and intestinal juice, respectively. Result shows: the concentration of borneol in Fufang Danshen intestinal adhesion pellets and Fufang Danshen tablet was 0.79% and 0.80%, respectively. Its in vitro dissolution was nearly 70% within 12 h in Fufang Danshen intestinal adhesion pellets, and in Fufang Danshen tablet, the dissolution was about 60% within 20 min and more than 90% within 40 min, and in artificial gastric juice, was less than 20% within 40 min but more than 80% till 150 min. Research suggests that in comparison with Fufang Danshen tablet, in vitro dissolution of borneol in the Fufang Danshen intestinal adhesion pellets showed an obvious sustained release behavior. The borneol in Fufang Danshen intestinal adhesion pellets was included with β-CD and prepared enteric preparations. To some extent, the stimulation on stomach and intestinal mucosa can be reduced and safety can be improved.
