BACKGROUND In this randomized controlled trial(RCT)comparing current acupuncture with carbamazepine for trigeminal neuralgia,meta-and sequential analyses were utilized.AIM To guide clinical decision making regarding the treatment of trigeminal neuralgia with carbamazepine.METHODS The RCT literature on needle comparison was searched in various Chinese biomedical databases including Chinese Biomedical Literature Database,Wanfang Data,VIP Database,as well as international databases such as Excerpt Medica Database,Cochrane Library,PubMed,and Web of Science,along with related clinical registration platforms such as World Health Organization International Clinical Trial Registry Platform,ChiCTR,and Clinical Trials up to 1 April 2020.Risk of bias was evaluated using the Cochrane Collaborative Risk Bias tool,primary outcome measures(pain reduction)were analyzed using STATA metaanalysis,outcome measures were analyzed using trial sequential analysis 0.9.5.10 Beta sequential analysis,GRADE was used to assess the evidence,and adverse reactions were documented.RESULTS This study analyzed 16 RCTs with a total of 1231 participants.The meta-analysis revealed a statistically significant difference in pain reduction between acupuncture and carbamazepine[standardized mean difference(SMD)=1.47;95%confidence interval(CI):0.99-1.95],although the quality of evidence was deemed to be of extremely low quality.Cumulative meta-analysis based on the year of publication indicated that carbamazepine treatment first demonstrated a statistically significant difference in pain reduction in 2014 and remained relatively stable over time[SMD=1.84;95%CI:0.22-3.47].Additionally,the number of adverse events associated with acupuncture was significantly lower compared to carbamazepine.CONCLUSION Acupuncture for trigeminal neuralgia is better than analgesia and safer than carbamazepine;however,firm conclusions still require a high-quality,multicenter,large-sample RCT to confirm these findings.
Carbamazepine(CBZ)is an anticonvulsant with very low water solubility,presenting as a white crystalline powder with poor mechanical properties and is hard to bend.To enhance CBZ's physicochemical properties,such as water solubility and mechanical properties,we selected six cocrystal coformers(CCFs):nicotinamide(NIC),benzamide(BZM),salicylic acid(SCA),fumaric acid(FMA),trimesic acid(TMA),and hesperetin(HPE).Six CBZ cocrystals were successfully prepared using the solution method.Fourier transform infrared spectroscopy(FT-IR),powder X-ray diffraction(PXRD),differential scanning calorimetry(DSC),and single crystal X-ray diffraction(SCXRD)were used to characterize the crystal structures and gain comprehensive insights into the six cocrystals.The mechanical,fluorescence,and solubility properties of the six cocrystals were tested.The results reveal that most of the prepared cocrystals exhibit improved water solubility and mechanical properties when compared to CBZ.Among them,the dissolution rate of cocrystals excluded from CBZ-HPE has increased by an average of 3 or 4 times compared to CBZ,while CBZ-HPE exhibits superior mechanical properties.Moreover,all six cocrystals possess better fluorescence performance than CBZ.We thoroughly evaluated the mechanical properties of the cocrystals through both experimental and theoretical approaches.This work provides a new direction for studying drug cocrystals to improve the physicochemical properties of drugs.
Maximizing the sustainable recycling of spent lithium-ion batteries(LIBs)shows economic and environmental significance.This study recovered lithium cobaltate(LiCoO_(2),LCO)from spent LIBs cathode powder.The recovered LCO was then combined with NaHSO_(3)to remove refractory organic pollutants of carbamazepine(CBZ)in water.The degradation of CBZ reached 80.0%within 60 min,by 1O_(2),SO_(4),OH and O_(2)^(-)generated in the LCO/NaHSO_(3)reaction.The electron transfer between Co(III)and Co(II)was beneficial to the generation of free radicals.The LCO/NaHSO_(3)degraded CBZ effectively in both secondary outlet water and tap water.However,high concentrations of inorganic ions(Cl^(−),HCO_(3)^(-),HPO_(4)^(2-),SO_(2)−4,NO_(3)^(-))and natural organic matter(humic acid,HA)could inhibit the degradation of CBZ.After three cycles,the stability of the LCO/NaHSO_(3)system was demonstrated by the maintained high efficiency in the degradation of CBZ.The obtained data indicate that the LCO/NaHSO_(3)system holds great application potential in the field of advanced oxidation degradation of pollutants.

Osteoarthritis(OA)presents a growing health concern,with substantial societal and healthcare burdens.Current management focuses on symptom relief,lacking disease-modifying options.Emerging research suggests the sodium channel Nav1.7 as a pivotal target in OA treatment.Preclinical studies demonstrate carbamazepine's efficacy in Nav1.7 blockade,offering significant joint protection in animal models.However,human trials are needed to validate these findings.Carbamazepine's repurposing holds promise for OA management,potentially revolutionizing treatment paradigms.Further research is essential to bridge the gap between preclinical evidence and clinical application,offering hope for improved OA management and enhanced patient quality of life.
