ABSTRACT
@#Exercise-associated muscle cramps (EAMC) is prevalent among athletes during training or competitions where they are subjected to strenuous activities for a prolonged period. To manage this painful condition, health practitioners have used numerous treatment modalities having massage done with adjunct application such as cold compress or liniment. Studies show that it is debatable which combination of treatment modalities is more effective on people affected by EAMC. Hence, this study aimed to present evidence-based data to show if there is a difference in the effectiviteness of the two modalities in treating EAMC. A total of thirty-two (32) athletic participants were enrolled in this study and a total of 40 treatment trials were included in the analysis of data. Each participant performed strenuous exercises meant to induce muscle cramps. The onset of muscle cramps was identified using a set criteria. After which, treatment was applied and the length of time that the cramp was resolved was recorded. Determining relief from muscle cramps was based on the characteristic of muscle hardness and the level of pain by using a numerical rating scale. Results showed that though majority of the participants verbalized preference for the ice treatment, analysis of data using one-way ANOVA revealed that there is no evidence to prove that there is a difference in the effectivity among the treatment modalities performed. In conclusion, though all modalities performed were able to relieve the EAMC, the use of adjunct treatment in addition to massage and stretching may have a placebo effect component, which improves the patient's perception of greater efficacy.

OBJECTIVE：To observe therapeutic efficacy and safe ty of Huhuang burn liniment on the prevention and treatment of radiation dermatitis patients with nasopharyngeal carcinoma （NPC）. METHODS ：Totally 129 NPC patients were collected from our hospital during Aug. 2018-Feb. 2020. They were numbered according to the order of radiotherapy ，the ones with odd number were included into observation group （65 cases）and the ones with even number into control group （64 cases）. Both groups received routine radiotherapy and skin nursing. Control group were evenly smeared with Shirun shaoshang cream in the radiation field during radiotherapy ，and observation group were smeared with Huhuang burn liniment. The smearing area should be 1 cm beyond the edge of radiation field ，3 times a day until the end of stage 1 radiotherapy（33-38 times in total ）. The skin lesions of the two groups were observed ；the appearance time and healing time of skin lesion ，RTOG score and NRS score were recorded. The levels of serum cytokines （TNF-α，IL-6，IL-8 and IL- 10）were detected in 2 groups at 0，15th and 30th time of radiotherapy. The occurrence of ADR was recorded in 2 groups during treatment. RESULTS ：The appearance time of skin lesion in observation group was significantly longer than control group ；the healing time of skin lesion in observation group was significantly shorter than control group （P＜0.01）. RTOG grading of radiodermatitis in the two groups was mainly grade 1，but no grade 3 or 4 was found. There was no significant difference in the proportion of patients with differen RTOG grades （P＞0.05）.

OBJECTIVE:To investigate transdermal behavior in vitro of total flavonoids and its monomer components in Guyu liniment. METHODS:Vertical Franz diffusion cell was adopted to perform a test on excised mouse skin as transdermal barrier. UV spectrophotometry was used to determine the content of total flavonoids,and HPLC to determine the content of monomer flavo-noid hydroxysafflor yellow A(HSYA)to observe transdermal absorption in vitro within 12 hours. RESULTS:The accumulative per-meation quantity Q of the total flavonoids and HSYA in Guyu liniment increased with time(t),demonstrating a significant correla-tion with t1/2,and transdermal absorption was in conformity with Higuchi equation (r=0.995 6,0.999 5);permeate flux of total flavonoids and HSYA were 126.24,47.516μg/(cm2·h). CONCLUSIONS:The transdermal behavior of total flavonoids in Guyu lin-iment is similar to that of HSYA. Both belong to matrix diffusion-type transdermal drug delivery system,with the characteristic of long-term sustained release.

ABSTRACT
Pain is normally treated with oral nonsteroidal anti-inflammatory agents and opioids. These drugs are dangerous and are responsible for many hospitalizations and deaths. It is much safer to use topical preparations made from plants to treat pain, even severe pain. Topical preparations must contain compounds that penetrate the skin, inhibit pain receptors such as transient receptor potential cation channels and cyclooxygenase-2, to relieve pain. Inhibition of pain in the skin disrupts the pain cycle and avoids exposure of internal organs to large amounts of toxic compounds. Use of topical pain relievers has the potential to save many lives, decrease medical costs and improve therapy.

ABSTRACT
Objective: To compare the electric resistance, stratum corneum thickness, and biochemical composition in acupoint and non-acupoint skin, and the osmotic properties of sinapine by acupoint and non-acupoint administration with Baijiezi Tufang (Baijiezi liniment prescription), to investigate the effect of dermal biophysical characteristics on cutaneous administration of sinapine, and to provide the experimental support of acupoint transdermal of Baijiezi Tufang for the treatment of asthma. Methods: Skin electrical resistance was measured with a specially designed meter, the thickness of stratum corneum was detected through microscope after the skin slice was stained by HE, and the skin biochemistry ingredients were compared by laser Raman spectroscopy. The permeability through acupoint and non-acupoint skin was examined with the modified Franz diffusion cell in vitro and tape-stripping in vivo, using sinapine as index. The content of sinapine was determined by HPLC. In in vivo permeability experiment, the stratum corneum was isolated and the distribution of drugs in various layers of acupoint and non-acupoint was compared. Results: The dermal resistance in acupoint was lower than that in non-acupoint (P < 0.05) and the stratum corneum of acupoint was thinner than that of non-acupoint (P < 0.05). However, the biochemistry ingredients of them were almost the same. The 24 h cumulative amount through the acupoint skin was about 6.8 times as that through the non-acupoint skin, and the steady-state flux of sinapine across acupoint skin was 6.1 times as that across in non-acupoint skin. Sinapine retention in acupoint skin was significantly higher than that in non-acupoint skin (P < 0.05) both in vitro and in vivo after 24 h of administration, and the retention in stratum corenum of acupoint was also higher than that in stratum corneum of non-acupoint at different time points within 24 h. Conclusion: The permeation and retention of sinapine in Baijiezi Tufang through acupoint skin are higher than those through non-acupoint skin, which relates to the lower electrical resistance and thinner stratum corenum of acupoint skin. It suggests the rationale evidence for acupoint administration in clinic application of Baijiezi Tufang.

ABSTRACT
Objectve To study the effect of anti-swelling and alleviating pain of Huzhangtongluo liniment. Method Mice with xylol-induced auricular swelling : the mice of each group were administered three times per day for 3 days. The inflammed mice were killed and punched a patch on left and right ear in 8 mm diameter, the weight margin of two patch was the rate of swelling. Mice with formalin-induced podalic swelling:the inflammed mice of each group were administered after 4 hours, by dislocating their cervical vetebra. The mice posterior feet were cut at the same place and weighed, the weight margin of left and right foot was the rate of swelling. Rat with granulation induced by cotton embedded under dermis:the rat of each group were administered and then killed after 6 hours, the granulation tissue of rat was separated, dried in oven at temperature of 70 ℃ and weighed, the data of dry weight was calculated and processed by statistics. The pain threshold of mice stimulated by heat:the pain threshold of administered mice was determined at 30, 60, 90 min. The threshold value was calculated as 60 s if the mice had no action such as licking foot, jumping or lifting foot after 60 s. Result Huzhangtongluo liniment can obviously inhibit auricular swelling induced by xylol and podalic swelling induced by formalin as well as granulation induced by cotton embeded under dermis. The preparations can clearly enhance pain-threshold value of mice in hot-plate method. Conclusion Huzhangtongluo liniment has the action of anti-swelling and alleviating pain.
