ABSTRACT
Objective:To explore the efficacy of Tuina combined hot compress in the treatment of lumbar disc herniation (LDH).Methods:A total of 90 patients with LDH low back and leg pain in Shijiazhuang Traditional Chinese Medicine Hospital from January 2019 to June 2020 were divided into two groups, 45 in each group. The control group was treated with Aceclofenac Sustained-release Tablets and Mecobalamin, and the observation group was treated with Tuina combined hot compress. Both groups were treated for 1 month and followed up 6 months. The Visual Analogue Scale (VAS) was used to evaluate the degree of pain. The Oswestry Dysfunction Index (ODI) was used to evaluate the recovery of lumbar function, and the improvement of daily activities of patients after treatment was evaluated. The conduction velocity of tibial nerve motor conduction velocity (TNMCV) and common peroneal nerve motor conduction velocity (CPNMCV) were measured by electromyography. The clinical effect was evaluated.Results:After 6 months of follow-up, the response rate of the observation group was 51.1% (23/45) and that of the control group was 28.9% (13/45) ( χ2=3.98, P=0.046). The VAS score of the observation group was significantly lower than that of the control group ( t=11.26, P<0.01). The ODI scores at 1 month after treatment and 6 months after follow-up were significantly lower than those in the control group ( t values were 7.19, 18.30, respectively, all Ps<0.001). The observation group 1 month after CPNMCV treatment and 6 months of follow-up ( t=2.08, 1.99), 1 month after TNMCV treatment and 6 months of follow-up ( t values were 2.46, 2.12, respectively) were significantly higher than those in the control group ( P<0.05). Conclusion:Tuina combined with hot compress can improve the nerve conduction velocity of lower limbs, relieve the symptoms of low back and leg pain in patients after LDH operation.
ABSTRACT
Objective Two co-crystals of isonicotinic acid hydrazide(INH)-malonic acid and INH-glutaric acid were prepared.The formation mechanism and intermolecular interaction were studied. Methods Three-dimensional structure of 2 co-crystals were obtained though single crystal X-ray diffraction(SXRD), and intermolecular interaction was analyzed using Hirshfeld surface method. Results INH-malonic acid crystalized in stoichiometric ratio of 1:0.5,while INH-glutaric acid in 1:1.Two co-crystals maintain their stable arrangement in space by hydrogen bond and van der Waals force. Conclusion With the existence of pyridine ring and carbohydrazide group in INH,which mainter-molecular interaction in co-crystal can be directly and clearly revealed by Hirshfeld surface analysis.
