Objective: To observe the clinical efficacy of tuina plus heat-sensitive moxibustion in treating temporomandibular disorders (TMD). Methods:Fifty patients with TMD were randomized into a treatment group and a control group, 25 cases in each group. The treatment group was intervened by tuina plus heat-sensitive moxibustion, while the control group was by medication. The Fricton-Shiffman craniomandibular index (CMI) was observed before and after intervention, and the clinical efficacies of the two groups were also evaluated. Results:There was no significant difference in comparing the CMI score between the two groups before intervention (P>0.05). After a treatment course, there were significant improvements in evaluating the CMI score in both groups (P<0.01), and the improvement was more significant in the treatment group than that in the control group (P<0.01). The total effective rate of the treatment group was significantly higher than that of the control group (P<0.01). Conclusion:Tuina plus heat-sensitive moxibustion is effective in treating TMD, and it’s safe, without adverse reactions, thus worth promoting in clinic.

Objective: To observe the clinical efficacy of warm needling moxibustion plus Tuina (Chinese therapeutic massage) for knee osteoarthritis (KOA).Methods: A total of 60 patients with KOA were randomized into an observation group and a control group by the random number table, with 30 cases in each group. The control group was treated with warm needling moxibustion, and the observation group was treated with additional Tuina treatment. The treatments were performed once every other day, for a total of 10 times. The visual analog scale (VAS) and Western Ontario and McMaster Universities osteoarthritis index (WOMAC) were scored before and after treatment, and the surface electromyography (sEMG) signals of quadriceps femoris were collected. Results: The total effective rate of the control group was 76.7％, and that of the observation group was 90.0％. The difference between the two groups was statistically significant (P<0.05). The WOMAC and VAS scores in both groups after treatment were improved, and the integrated electromyography (iEMG) and median frequency (MF) of quadriceps femoris were increased. The intra-group differences were statistically significant (P<0.05). After treatment, the WOMAC and VAS scores in the observation group were lower than those in the control group, and the differences between the two groups were statistically significant (P<0.05). The improvement of quadriceps femoris function in the observation group was more notable than that in the control group, and the iEMG value and MF were significantly higher than those in the control group (P<0.05). Conclusion: Warming needling moxibustion plus Tuina can effectively relieve the pain in patients with KOA, improve their daily activity function, and increase the sEMG signals of the quadriceps femoris.

Objective:To analyze the viral nucleic acid and cytokines in 12 children with 2019-nCoV infection.Methods:Clinical and laboratory data of the children diagnosed with 2019-nCoV infection in Guangzhou Women and Children′s Medical Center from January to April 2020 were retrospectively analyzed. Throat and anal swabs were collected on alternate days for the detection of 2019-nCoV nucleic acid by fluorescence quantitative PCR. Flow cytometry was used to detect serum cytokines including IFN-γ, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-17A, IL-17F, IL-22, TNF-α and TNF-β during the early (both throat and anal swab tests were positive), the intermediate (throat swab test was negative, while anal swab test remained positive), and the convalescence (both throat and anal swab tests were negative) stages of infection.Results:A total of 12 children were enrolled in this study. The male-to-female ratio was 5∶1. The average age was (7.0±4.3) years. There were two asymptomatic, five mild and five common cases. No severe or critical cases were involved. Initially, throat and anal swab nucleic acid tests were simultaneously positive in nine children newly diagnosed in our hospital and the median time of viral shedding in throat swab was longer than that in throat swab [32 (4.5, 45.0) d vs 3 (2, 9) d, Z=11.0, P=0.010]. The median difference of viral shedding time between anal swab and pharyngeal swab was 25.5 (1.5, 42.8) d. The overall levels of serum cytokines IL-17A, IL -4 and IL-5 in different stages of the disease (early, intermediate and convalescence stage) were statistically different ( Z or F, P values were 8.33, 0.016; 5.36, 0.010 and 6.56, 0.004, respectively), and a significant increase was observed in the intermediate stage of infection. IL-17F, IL-2 and IL-22 were all increased during the infection, but there was no significant statistical difference among the three stages ( P>0.05). Conclusions:It was noted that intestinal viral shedding needed a longer time. Although the infectivity has not been determined, higher requirements have been put forward for disease prevention and control. Cytokines secreted by Th2 and Th17 cells were involved in the immune response in children with non-severe 2019-nCoV infection. Monitoring viral shedding and cytokine changes in pediatric patients would be conducive to disease assessment.
