Traditional Chinese medicine ointment combined with tuina therapy in treatment of pain and swelling after total knee arthroplasty

BACKGROUND The most effective treatment for knee joint pain is total knee arthroplasty(TKA),but the risk of pain and swelling in patients after surgery is high.Ice application,ankle pump exercise and non-steroidal anti-inflammatory painkillers are the primary clinical treatments after surgery.However,long-term use of nonsteroidal anti-inflammatory pain relievers can easily cause gastrointestinal damage.Traditional Chinese medicine(TCM)ointments and tuina therapy integrate TCM and manipulation,which effectively promotes the penetration of TCM into the skin lesions,improves local blood circulation and inflammatory reaction and has good long-term effects on patients.AIM To evaluate the efficacy of TCM ointment combined with tuina therapy in the treatment of pain and swelling after TKA.METHODS The randomized controlled clinical trial enrolled 80 patients who underwent TKA via the same procedure.The patients were randomly divided among the treatment group(n=40)and the control group(n=40).The control group was given an analgesia pump in addition to oral painkillers as the postoperative intervention.The treatment group received TCM ointment with tuina therapy in addition to the analgesia pump and oral painkillers in the postoperative period.The following variables were recorded 3 d before surgery and 3 d,7 d and 14 d after surgery:Visual analogue scale(VAS)score;skin temperature;circumferences at 15 cm above and below the patella;maximum active knee flexion angle;and the knee injury and Osteoarthritis Outcome score(KOOS).RESULTS After treatment,VAS was significantly lower in the treatment group than the control group at 7 d(t=7.536,P<0.001)and 14 d(t=8.563,P<0.001).The skin temperature of participants in the treatment group was significantly lower than that in the control group at 7 d(t=2.968,P=0.004)and 14 d(t=4.423,P<0.001).The circumference values of the two positions in the treatment group were lower than those in the control group at 7 d[t=2.315,P=0.023(above);t=2.121,P=0.037(below)]and 14 d[t=2.374,P=0.020(above);t=2.095,P=0.039(below)].After 14 d of treatment,the maximum active knee flexion angle and KOOS of the two groups were significantly improved but were significantly higher in the treatment group(P<0.05 for both).CONCLUSION TCM ointment and tuina therapy have significant advantages over standard care in the treatment of pain and swelling after TKA.This additional treatment may improve knee function but additional studies are needed to confirm our observations.

Effect of Acute Pancreatitis on the Pharmacokinetics of Chinese Herbal Micron Liuhe Pill Ointment (微米六合丹) in Rats

Objective： To explore the effect of acute pancreatitis （AP） on the pharmacokinetics of herbal ointment micron Liuhe Pill （微米六合丹, MLHP） components in anesthetized rats. Methods： Rats were randomly divided into a AP model group （n=6） and a normal group as a control （n=6）. The rat model of AP was induced by intraperitoneal injection of L-arginine in rats （15 mg/kg, twice, interval 1 h）. Chinese herbal ointment MLHP was used externally on the belly after the 2nd injection for 48 h in both groups. Emodin, rhein, aloe emodin, physcion, chrysophanol from MLHP were detected and quantified in rat serum and pancreas （at 48 h） by high performance liquid chromatography-tandem mass spectrometry. Results： Among the five components, only emodin, aloe emodin and physcion from MLHP were detected in all rat serum and most of the rats＇ pancreas. Rhein and chrysophanol were not detected in both serum and pancreas. T1/2α of emodin and physcion in MLHP were obviously shorter in the AP model group than those in the normal group （P〈0.05）, while there was no difference for T/2α of aloe emodin. The peak concentration and area under curve of all three components were much higher in the AP group than those in the normal group with MLHP in external application for 48 h （P〈0.05）. Furthermore, the mean residence time （MRT） and maximum plasma concentration （Tmax） of emodin and aloe emodin were obviously longer in the AP model group than those in the normal control group （P〈0.05）. There was no significant difference for Ka of all components between the two groups. Emodin could be detected in all rats＇ pancreas at 48 h in both groups, while its mean pancreatic concentration was higher in the AP model group than in the normal group （0.61 ± 0.54 ng/mL, 0.42 ± 0.37 ng/mL, respectively, P〈0.05）. Aloe emodin could be detected in all rats＇ pancreas at 48 h in both groups and their mean pancreatic concentration were similar （0.31± 0.24 ng/mL, 0.33 ±0.17 ng/mL, respectively, P〉0.05）. Physcion could be detected in pancreas of most rats in the AP model while only two rats in the normal group. Conclusion： AP could significantly affect the pharmacokinetics of absorbed components of Chinese herbal MLHP ointment in rats.

Heijiangdan Ointment(黑绛丹膏)Relieves Oxidative Stress from Radiation Dermatitis Induced by ^(60)Co γ-Ray in Mice

Objective：To investigate the effects of Heijiangdan Ointment（黑绛丹膏,HJD） on oxidative stress in （60）Co γ-ray radiation-induced dermatitis in mice.Methods：Female Wistar mice with grade 4 radiation dermatitis induced by ^（60）Co γ-rays were randomly divided into four groups（n=12 per group）;the HJD-treated,recombinant human epidermal growth factor（rhEGF）-treated,Trolox-treated,and untreated groups,along with a negative control group.On the 11 th and 21 st days after treatment,6 mice in each group were chosen for evaluation.The levels of superoxide dismutase（SOD）,malondialdehyde（MDA）,and lactate dehydrogenase（LDH） were detected using spectrophotometric methods.The fibroblast mitochondria were observed by transmission electron microscopy（TEM）.The expressions of fibroblast growth factor 2（FGF-2） and transforming growth factor β1（TGF-β1） were analyzed by western blot.Results：Compared with the untreated group,the levels of SOD,MDA and LDH,on the 11 th and 21 st days after treatment showed significant difference（P〈0.05）.TEM analysis indicated that fibroblast mitochondria in the untreated group exhibited swelling and the cristae appeared fractured,while in the HJD group,the swelling of mitochondria was limited and the rough endoplasmic reticulum appeared more relaxed.The expressions of FGF-2 and TGF-β1 increased in the untreated group compared with the negative control group（P〈0.05）.After treatment,the expression of FGF-2,rhEGF and Trolox in the HJD group were significantly increased compared with the untreated group（P〈0.05）,or compared with the negative control group（P〈0.05）.The expression of TGF-β1 showed significant difference between untreated and negative control groups（P〈0.05）.HJD and Trolox increased the level of TGF-β1 and the difference was marked as compared with the untreated and negative control groups（P〈0.05）.Conclusion：HJD relieves oxidative stress-induced injury,increases the antioxidant activity,mitigates the fibroblast mitochondrial damage,up-regulates the expression of growth factor,and promotes mitochondrial repair in mice.
