Epalrestat is effective in treating diabetic foot infection and can lower serum inflammatory factors in patients.

This study was designed to determine the efficacy of epalrestat on patients with diabetic foot infection (DFI) and its effects on serum inflammatory factors in the patients. METHODS: The data of 80 patients with DFI treated in the First Affiliated Hospital of Jiangxi Medical College from May 2020 to May 2022 were analyzed retrospectively. Among them, patients who received routine comprehensive treatment were enrolled into the control group (n=37), and those who received epalrestat on the basis of routine comprehensive treatment were enrolled into the study group (n=43). The changes of serum inflammatory factors before and after treatment, granulation tissue grading and efficacy in the two groups were analyzed and compared, and the wound healing time, hospitalization time and adverse reactions (including nausea and vomiting, dizziness, headache, pruritus, etc.) of the two groups were statistically analyzed. The prognosis of the patients within 1 year after treatment was analyzed, and the independent risk factors of poor prognosis were analyzed through logistic regression. RESULTS: Before treatment, the two groups were not significantly different in the levels of tumor necrosis factor-α (TNF-α), high sensitivity C-reactive protein (hs-CRP), and interleukin-6 (IL-6), while after treatment, the levels decreased significantly in both groups, with significantly lower levels in the study group than those in the control group. The study group had a significant lower proportion of patients with grade 0/grade 1 granulation tissue than the control group, and had a significantly higher proportion of patients with grade 2/grade 4 granulation tissue than the control group, but the proportion of patients with grade 3 granulation tissue in the two groups was not greatly different. The study group experienced notably shorter wound healing time and hospitalization time than the control group. A notably higher overall response rate was found in the study group than that in the control group. In addition, the total incidence of adverse reactions was not greatly different between the two groups. BMI, diabetes mellitus type, Wagner grading and classification of diabetic foot infection were found to be the risk factors affecting the prognosis of patients, and Wagner grading was an independent risk factor affecting the prognosis of patients. CONCLUSION: Epalrestat is effective in treating DFI, because it can lower the levels of serum inflammatory factors, shorten the time of wound healing and hospitalization, and promote the growth and recovery of granulation, without increasing adverse reactions. Therefore, it is worthy of clinical promotion.

Dynamic electromyography findings of the lower leg muscles during walking in spastic cerebral palsy children with hindfoot valgus.

BACKGROUND: Hindfoot valgus is one of the most prevalent foot deformities in cerebral palsy children. Investigating the muscle activation patterns of cerebral palsy children with hindfoot valgus is crucial to understand their abnormal gait different from typically developing children. METHODS: Electromyography data of 20 cerebral palsy children with hindfoot valgus and 20 typically developing children were recorded for tibialis anterior, peroneal longus, and gastrocnemius medialis. The activation onset and offset times, normalized peak electromyography amplitude, average electromyography amplitude and integral electromyography amplitude for 20 completed cycles were averaged for data analysis. The co-activation index and activation percentage of peroneal longus were used to evaluate the co-activation level for tibialis anterior and peroneal longus muscles. FINDINGS: Compared with typically developing children, the activation onset of tibialis anterior and the activation offset of tibialis anterior, peroneal longus, and gastrocnemius medialis were significantly delayed in cerebral palsy children; moreover, the muscle activation durations of tibialis anterior, peroneal longus, and gastrocnemius medialis were significantly longer, and the normalized average electromyography amplitude of tibialis anterior, peroneal longus and gastrocnemius medialis, and the normalized integral electromyography amplitude of tibialis anterior were significantly lower in cerebral palsy children. Furthermore, for cerebral palsy children, the co-activation index was greater, and the peroneal longus muscles activation percentage was lower in the stance phase and greater in the swing phase than that of typically developing children. INTERPRETATION: The lower leg muscle activation patterns in cerebral palsy children were found to be abnormal.

High-power continuous-wave narrow-linewidth 253.7 nm deep-ultraviolet laser.

A 760 mW stable continuous-wave narrow-linewidth 253.7 nm deep-ultraviolet laser is developed for laser cooling of mercury atoms. It is based on a high-power 1014.8 nm room-temperature fiber laser amplifier and two cascaded efficient frequency-doubling stages. The saturated absorption spectrum of Hg202 on the 6S01-6P13 transition is demonstrated with a high signal-to-noise ratio. This deep-ultraviolet laser has significant applications in quantum optics and laser cooling of mercury atoms in 2D and 3D magneto-optical traps.

[Observation on therapeutic effect of acupuncture on early peripheral facial paralysis].

OBJECTIVE: To observe therapeutic effects of acupuncture at different opportunities on peripheral facial paralysis. METHODS: Fifty-two cases were randomly divided into a treatment group (n=28) and a control group (n=24). The treatment group at the acute stage (1-10 days) were treated with acupuncture at Dicang (ST 4), Jiache (ST 6), Yangbai (GB 14), etc., with less than 4 points selected on the face and with shallow puncture, and 10 days later electroacupuncture were added at acupoints selected routinely; the control group were treated with the same methods as the treatment group but acupuncture was not given at the acute stage. RESULTS: The cured rate of 78.6% in the treatment group was significantly higher than 50.0% in the control group (P < 0.05). CONCLUSION: Early acupuncture is a key for achieving the best therapeutic effect on facial paralysis.
