[Evaluation of efficacy of denture occlusal plate combined with comprehensive physical therapy for temporomandibular joint disc displacement without reduction].

PURPOSE: To explore the efficacy of denture occlusal plate combined with comprehensive physical therapy for temporomandibular joint disc displacement without reduction(ADDwoR). METHODS: Sixty patients of ADDwoR and dentition defect or severely worn teeth who visited the Department of Orthodontics and Prosthodontics of Hengshui People's Hospital from January 2019 to December 2020 were selected and randomly divided into denture occlusal plate group (group A) and denture occlusal plate + comprehensive physical therapy group (group B) according to the treatment methods. Maximum mouth opening (MMO) and visual analog pain score(VAS) among all patients were recorded before treatment and every three weeks during three months of treatment. Cone-beam CT(CBCT) was taken before and 3 months after treatment. The changes in clinical efficacy indicators before and after treatment and CBCT data between the two groups were analyzed. Statistical analysis was performed with SPSS 26.0 software package. RESULTS: The differences of VAS of group A and B were statistically significant from before treatment to three weeks after treatment(P＜0.05), and group B decreases more. From 3 weeks after treatment, there was a significant difference of group B for MMO and VAS before treatment (P＜0.05). From 9 weeks after treatment, there was a significant difference of group A for MMO before treatment (P＜0.05), but there was no significant difference in MMO and VAS between group A and B(P＞0.05). CBCT showed narrowed anterior joint space, widened posterior joint space, enlarged superior joint space, decreased horizontal angle of the condyle and increased slope of joint nodules (P＜0.05). The difference between joint depth, anteroposterior diameter of the condyle, internal and external diameter was not significant (P＞0.05). There was significant differences in anterior, superior, and posterior joint space, condylar level angle, and slope of joint nodules of group B compared with group A(P＜0.05). CONCLUSIONS: Denture occlusal plate can effectively improve symptoms of ADDwoR, and denture occlusal plate combined with comprehensive physical therapy can quickly improve mouth opening and reduce pain in the joint area.

Therapeutic Effects of a Traditional Chinese Medicine Formula Plus Tamoxifen vs. Tamoxifen for the Treatment of Mammary Gland Hyperplasia: A Meta-Analysis of Randomized Trials.

As a common disorder that accounts for over 70% of all breast disease cases, mammary gland hyperplasia (MGH) causes a severe problem for the quality of patients' life, and confers an increased risk of breast carcinoma. However, the etiology and pathogenesis of MGH remain unclear, and the safety and efficacy of current western drug therapy for MGH still need to be improved. Therefore, a meta-analysis was conducted by our team to determine whether a TCM formula named Ru-Pi-Xiao in combination with tamoxifen or Ru-Pi-Xiao treated alone can show more prominent therapeutic effects against MGH with fewer adverse reactions than that of tamoxifen. Studies published before June 2017 were searched based on standardized searching rules in several mainstream medical databases. A total of 27 articles with 4,368 patients were enrolled in this meta-analysis. The results showed that the combination of Ru-Pi-Xiao and tamoxifen could exhibit better therapeutic effects against MGH than that of tamoxifen (OR: 3.79; 95% CI: 3.09-4.65; P < 0.00001) with a lower incidence of adverse reactions (OR: 0.35; 95% CI: 0.28-0.43; P < 0.00001). The results also suggested that this combination could improve the level of progesterone (MD: 2.22; 95% CI: 1.72-2.71; P < 0.00001) and decrease the size of breast lump (MD: -0.67; 95% CI: -0.86 to -0.49; P < 0.00001) to a greater extent, which might provide a possible explanation for the pharmacodynamic mechanism of Ru-Pi-Xiao plus tamoxifen. In conclusion, Ru-Pi-Xiao and related preparations could be recommended as auxiliary therapy combined tamoxifen for the treatment of MGH.

A randomized trial of Chinese medicine Lirukang Granule combined with psychological intervention for cyclomastopathy and menoxenia.

OBJECTIVE: To observe the influence of therapy with Chinese medicine Lirukang Granule (, LRKG) combined with psychological intervention on anxiety states and sex hormones in patients with cyclomastopathy and menoxenia. METHODS: A total of 470 subjects were randomly assigned to three groups by the net-central randomization system, the treatment group (161 patients, treated with LRKG and psychological intervention), the Chinese medicine group (157 patients, treated with LRKG), and the psychological intervention group (152 patients, treated with psychological intervention). The dose of LRKG was 12 g three times per day; psychological intervention included establishing relations, cognitive intervention and psychological persuasion, 30-40 min per session, once a week. The therapy duration for all groups was three months. The efficacy was compared and anxiety state/State-Trait Anxiety Invertory (STAI) scoring was measured before and after treatment. The serum estradiol (E2), progesterone (P), prolactin (PRL) and follicle stimulating hormone (FSH) levels of 60 patients selected randomly from each group during the luteal phase were measured before and after treatment, and a group of 20 healthy women were evaluated for comparison. A follow-up was arranged for one year after treatment. RESULTS: Thirty subjects were lost to follow-up. (1) Comparison of efficacy: the markedly effective rate and the total effective rate of the treatment group were 86.67% (131/150) and 98.00% (147/150), respectively; of the Chinese medicine group, 64.58% (93/144) and 90.27% (130/144), respectively; and of the psychological intervention group, 0% (0/146) and 3.42% (5/146), respectively. The markedly effective rate and the total effective rate in the treatment group were significantly higher than those in the Chinese medicine and psychological intervention groups (P < 0.05). (2) Comparison of STAI scoring: STAI scoring was decreased dramatically in the treatment group after treatment compared with that of the Chinese medicine group (P < 0.01), but there was no significant difference compared with the psychological intervention group. (3) Comparison of levels of sex hormones: E2, P, PRL and FSH of the three patient groups were disordered before treatment, and significantly different from healthy women (P < 0.01). After treatment, the levels of P and FSH of the treatment group were significantly increased (P < 0.01), E2 and PRL were significantly reduced, which were also significantly decreased compared with the psychological intervention groups (P < 0.01). (4) FOLLOW-UP: the markedly effective rate and the total effective rate of the treatment group remained higher than those of the other two groups after one year of treatment (P < 0.05). (5) Adverse reactions: no obvious adverse reactions were found among the three groups. CONCLUSIONS: Therapy with Chinese medicine combined with psychological intervention was effective for short-term and long-term treatment of cyclomastopathy and menoxenia. The mechanism might be related to the regulation of sex hormones.
