Clinical observation on the treatment of sympathetic cervical spondylosis with meridian acupoint massage combined with curvature traction

Objective:To evaluate the clinical effect of meridian acupoint massage combined with curvature traction on sympathetic cervical spondylosis its influence on heart rate variability and norepinephrine concentration.Methods:80 patients with sympathetic cervical spondylosis were divided into the treatment group and control group randomly,with 40 patients in each group.Patients in the two groups were treated with massage on the basis of curvature traction.Among them,the treatment group was treated with meridian acupoint massage,while the control group was treated with routine massage.Each subject was treated once a day for 2 weeks.Before and after treatment,VAS,NRS,"20 score method",NDI,JOA,and Borden's method were used to evaluate the pain,sympathetic symptoms and cervical function of the two groups.At the same time,the changes of RR interval standard deviation and urine noradrenaline concentration were also observed.Finally the clinical efficacy of the two groups were evaluated.Results:The cure rate of the treatment group was 62.50%,while it was 40.00%in the control group,and the effective rate of the treatment group was 95.00%,the total effective rate of the control group was 80.00%,the treatment group was superior to the control group in both cure rate and total effective rate(P<0.05).During post-therapy,VAS score,NRS score,sympathetic symptom score,cervical physiological curvature,NDI score,and noradrenaline concentration in urine in both groups were lower than those of pre-treatment(P<0.01),JOA score and heart rate variability SDNN value were significantly higher(P<0.01),and the treatment group was superior to the control group(P<0.01).Conclusion:Meridian acupoint massage combined with curvature traction has a significant clinical effect on sympathetic cervical spondylosis,which is worth further promotion and application.

Clinical symptoms of cervical and shoulder MTrPs combined with the "third stage" dialectical traction in the treatment of cervical radiculopathy and its effect on the serum inflammatory factors of patients

Objective:To observe the clinical efficacy of acupotomology in the treatment of cervical and shoulder myofascial pain trigger point for cervical radiculopathy,and to detect its effect on COX-2,PGE2,5-HT,TNF-α and other inflammatory factors.Methods:A total of 110 CSR patients were selected as the research objects and divided into observation group(Acupotomology to release the trigger points of myofascial pain in neck and shoulder combined with"three-stage"dialectical traction method)and control group(conventional acupuncture combined with"Stage 3"dialectical traction)with 55 cases.Before and after treatment,the two groups were compared by improving the efficacy of MacNab,simplifying the SCORE of Mc Gill Pain Scale,measuring cervical curvature and serum levels of inflammatory factors such as COX-2,PGE2,5-HT and TNF-α.Results:After two weeks of treatment,the total effective rate of the observation group was 96.36%,higher than that of the control group(83.63%),and the difference was statistically significant(P<0.05).After the treatment,PRI,VAS,PPI and other scores of the two groups were all lower than those before the treatment,with statistical significance(P<0.05).However,there was no statistically significant difference in PRI,VAS and PPI scores between the two groups after treatment(P>0.05).The serum inflammatory factors of coX-2,PGE2,5-HT and TNF-αin the two groups were significantly lower after treatment than before treatment(P<0.05).However,the comparison of cox-2,PGE2,5-ht and TNF-αbetween the two groups showed no statistical significance(P>0.05).The cervical curvature values measured after treatment were significantly increased compared with those before treatment,and the difference was statistically significant(P<0.05).There was no statistically significant difference between the two groups(P>0.05).Conclusion:The combination of acumotomology and"three-stage"dialectical traction method can significantly improve the pain and discomfort of patients with cervical radiculopathy,significantly reduce the symptoms,restore the physiological curvature of cervical vertebra,and reduce the inflammatory factors in serum.

Triclosan-conjugated,Lipase-responsive Polymeric Micelles for Eradication of Staphylococcal Biofilms

Bacterial biofilms present a significant challenge in treating drug-resistant infections,necessitating the development of innovative nanomedicines.In this study,we introduce triclosan-conjugated,lipase-responsive polymeric micelles designed to exploit biofilm properties and serve as a responsive drug delivery platform.The micelles were created using an amphiphilic block polymer synthesized via ring-opening polymerization ofε-caprolactone(CL)and triclosan-containing cyclic trimethylene carbonate(MTC-Tri).Poly(ethylene glycol)(PEG-OH)acted as the macro-initiator,resulting in micelles with a PEG shell that facilitated their penetration into bacterial biofilms.An important advantage of our micelles lies in their interaction with local bacterial lipases within biofilms.These lipases triggered rapid micelle degradation,releasing triclosan in a controlled manner.This liberated triclosan effectively eliminated bacteria embedded in the biofilms.Notably,the triclosan-conjugated micelles displayed minimal toxicity to murine fibroblasts,indicating their biocompatibility and safety.This finding emphasizes the potential application of these micelles in combatting drug resistance observed in bacterial biofilms.Our triclosan-conjugated,lipase-responsive polymeric micelles exhibit promising characteristics for addressing drug resistance in bacterial biofilms.By harnessing biofilm properties and implementing a responsive drug delivery system,we seek to provide an effective solution in the fight against drug-resistant bacteria.

Responsive Polymeric Nanoparticles for Biofilm-infection Control

With the emergence of multidrug resistance(MDR)in many pathogens,bacterial infections are becoming a growing threat to public health.The frightening scenario is due largely to the formation of biofilms,in which the bacteria are extremely recalcitrant to the conventional antibiotic regimens.To address the emergence of MDR and biofilm-associated infections,numerous polymer-based materials have been designed and prepared recently.The subject of this perspective is the recent development of polymer-based materials that have been applied to combat multidrug-resistant pathogens,to prevent the formation of biofilms,or enhance the eradication efficacy to mature biofilms via killing biofilm-bacteria or dispersing biofilms.The advantages and shortcomings of these polymer-based materials are discussed,as well as the challenges we are facing in the clinical translation of these systems.
