The clinical and pathological diagnosis of oral submucous fibrosis depended on clinical and pathological diagnostic standards. The oral submucous fibrosis involving different portions and size in the mouth was observed and recorded. The portions of oral cancer, clinical findings and symptoms, cancerous size, the conditions of the local lymphatic nodes and of oral submucous fibrosis correlated with squamous cell carcinoma in the mouth, oral leukoplakia, lichen planus were also observed and recorded. In twenty-nine patients with oral squamous cell carcinoma, duration from oral submucous fibrosis transformed into oral cancer ranged from 2 to 15 years with an average year of 6.69. The serious degrees of oral submucous fibrosis in the patients with oral cancer were that the moderately advanced stage was found in 3 cases (10.34%) and the advanced stage was found in 26 cases (89.65%). The cancerous portion was that the buccal mucosa was found in 9 cases (31.03%);the tongue was found in 14 cases (48.27%);the other portion was found in the rest 6 cases (20.68%). Among the twenty-nine patients twenty-three patients with squamous cell carcinoma were associated with leukoplakia (79.31%), five patients were associated with lichen planus (17.24%). Twenty-seven patients (93.1%) had habits of betel quid chewing, smoked cigarette and drank alcohol, the rest two patients had habits of betel quid chewing and cigarette smoking. The present study demonstrates that oral submucous fibrosis is a real precancerous lesion and may transform into squamous cell carcinoma in the mouth.展开更多

The patients in the control group were given multipoint injection of triamcinolone acetonide (40 mg/time) in the basal region of oral mucosal regions. On this basis, the patients in the observation group were given additional Danshen injection (4 mL/time), 1 time/week, for 12 times. VAS was used for evaluation. The oral mucosa lesion area and mouth opening were measured. The morning fasting peripheral venous blood before and after treatment in the two groups was collected. The blood rheometer was used to detect the whole blood viscosity [high shear (HS), moderate shear (MS), and low shear (LS)], plasma viscosity (PV), and fibrinogen (FIB). ELISA was used to detect the serum TGF-β1 and IL-6 levels.Results: VAS score in the observation group was significantly reduced (P<0.05), mucosal lesion area was significantly less than that in the control group (P<0.05), and mouth opening was significantly greater than that in the control group (P<0.05). LS, MS, PV, and FIB after treatment in the observation group were significantly reduced when compared with before treatment (P<0.05), while LS, MS, HS, PV, and FIB after treatment in the control group were not significantly changed (P>0.05). TGF-β1 and IL-6 levels after treatment in the observation group were significantly lower than those in the control group (P<0.05).Conclusions: Danshen injection in combined with local injection of triamcinolone acetonide in the treatment of OSF can effectively reduce the serum TGF-β1 and IL-6 levels, inhibit the connective tissue fibrosis, and improve the pain, oral mucosal lesion area, and mouth opening, with a satisfactory clinical effect.展开更多

Eight mice from each group were sacrificed every 4 weeks since 8 weeks post treatment. Changes in histopathologic features, levels of collagen type Ⅰ and collagen type Ⅲ, and angiogenesis were measured.Results: In the 8th week, epithelium atrophy, collagen cumulation and micrangium pathologic changes in the lamina propria were observed in the oral mucosa. In the 20th week, hyaline degeneration of the connective tissues was observed on the tongue and palate mucosa. The angiogenesis and collagen type Ⅰ changed significantly as the diseases advanced(P < 0.05); however, collagen type Ⅲ was not statistically different.Conclusions: An OSF model involving mice can be rapidly induced by drinking a highdose of arecoline. OSF angiogenic changes in mice primarily decrease and collagen accumulation is mainly collagen type Ⅰ.展开更多

The results indicated that the cell dimensions (area, perimeter, all kinds of diameter) and nuclear cytoplasmic ratio in OSF were between normal mucosa and dysplasia as well as carcinoma. The former showed a progressive decrease (P<0.01), and the latter showed a progressive increase (P<0.01). The dimensions of the nuclei did not show considerable differences among the groups (P>0.05). A series of discriminant functions had been developed with stepwise discriminant analysis, the agreement ratio for OSF was 93.75%. The decrease of cell area and the increase of nuclear cytoplasmic ratio could reflect a malignant progress. The cell morphometric model could discriminate OSF well from other groups, suggesting that the change of the epith展开更多

A healthy oral cavity enables person to perform daily activities without any limitations. However, any disturbance may result in impaired QoL. The oral health-remains an essential element of people's health and well-being. In recent years, the tradition of clinical practice and research has been changed by incorporating QoL assessment, as it helps in assessment of patients' needs and monitoring treatment responses. Oral potentially malignant disorders(OPMDs) are a group of chronic disorders including oral leukoplakia(OL), oral lichen planus and oral submucous fibrosis(OSF). It is evident that patients with OPMDs experience significant health-related symptoms, functional limitations and psycho-social impairment, compromising their Qo L. Moreover, the worsening of Qo L has been associated with advanced stages of OPMDs. Despite of increasing number of OPMD cases in recent decades, limited literature is available regarding QoL in this population. Although, there is higher prevalence of habit-related OPMDs, particularly OSF and OL in Southern Asian countries, only a few studies have been performed in these populations. Moreover, these studies administered generic Qo L instruments, which offer less sensitivity to clinical changes. However, condition-specific instruments are more sensitive and allows better measurement of QoL. As the impacts of different conditions on OHRQoL may vary, the development and validation of a QoL instrument specific to each clinical entity of OPMDs is currently needed.展开更多
