BACKGROUND:A number of studies have been conducted on the prevention of enamel demineralization in orthodontic treatment, but no work has been carried out on the comparative studies addressing manual toothbrush, orthodontic fur V brush and interdental brush. OBJECTIVE:To compare the efficacy of manual toothbrush, orthodontic fur V brush and interdental brush on enamel decalcification during orthodontic treatment. METHODS:Adolescents, aged 12 to 17 years old, were randomly and averagely divided into three groups: manual toothbrush, orthodontic fur V brush, and interdental brush groups. Enamel decalcification index and augmenter of enamel decalcification index were examined and calculated by the same orthodontist before treatment and 1 year later. RESULTS AND CONCLUSION: There was no statistical difference in the enamel decalcification index among the three groups at the beginning (P > 0.05). After 1 year of treatment, the enamel decalcification index of each group was higher than that at the beginning (P < 0.05); the enamel decalcification index and augmenter of enamel decalcification index in the three groups were ranked as folows: orthodontic Fur V toothbrush group < manual toothbrush < interdental toothbrush group , and there was a statistical significant difference among the three groups (P < 0.05). Orthodontic fur V brush is proved to have advantages over manual toothbrush and interdental brush in the respect of controling enamel decalcification, and interdental brush has no good effect on preventing enamel demineralization while it is used alone.

Objective To observe the clinical effect of Danggui Sini decoction for treatment of patients with chronic non-atrophic gastritis and spleen-stomach deficiency cold syndrome.Methods A prospective randomized control trial was conducted, including 126 in- and out-patients with chronic non-atrophic gastritis diagnosed by gastroscopy and spleen-stomach deficiency cold syndrome differentiated by traditional Chinese medicine (TCM) method admitted to Chinese Medicine Hospital of Haikou City. They were randomly assigned to an observation group (65 cases) and a control group (61 cases). The patients in observation group were given Danggui Sini decoction with addition or/with subtraction of ingredients according to individual situation (ingredients: angelica 15 g, ramulus cinnamomi 15 g, paeonia 15 g, asari 5 g, glycyrrhizae 10 g, Chinese jujube 12, medulla tetrapanacis 10 g ). The warm 200 mL (one dose) decoction was divided into two parts, one part was taken orally before a meal, twice daily, the therapeutic course was 4 weeks and in one week only 6 doses were applied; while the patients in control group, omeprazole capsules (dissolved in intestine), each time 20 mg, once a day combined with domperidone (bite phenanthroline) 10 mg each time, 3 times a day were given. After 4 weeks of treatment, the clinical efficacy, the total integral of symptoms, the therapeutic effect of TCM symptoms score, the improvement of the therapeutic effect of mucosal histological and changes of the number of patients with the patholoyical changes of mucosa under gastroscopy were observed.Results The total effective rate in the observation group was significantly higher than that in the control group [96.9% (63/65) vs. 86.9% (53/61),P < 0.05]. After treatment, the total integral of symptoms and the integrals of main TCM symptoms after treatment were lower than those before treatment, the degree of decrease in the observation group being more marked (the total integral of symptoms score: 12.36±2.11 vs. 15.94±2.37, epigastric distention integral score: 1.23±0.72 vs. 2.12±0.78, epigastric pain score: 1.18±0.67 vs. 2.25±0.94, thermophilic and like pressure integral score: 1.03±0.46 vs. 1.62±0.79, anorexia: 1.06±0.57 vs. 1.43±0.53, integral of loose stools score: 1.36±0.43 vs. 1.67±0.58, lassitude integral score: 1.24±0.32 vs. 1.65±0.42, allP < 0.05). Under gastroscope, the efficacy of mucosal histological change was significantly higher in observation group than that in control group [90.77% (59/65) vs. 81.97% (50/61),P < 0.05]. After treatment, the numbers of patients with chronic inflammatory cell infiltration (47 cases vs. 54 cases), erythema exudation (28 cases vs. 30 cases), flat erosion (8 cases vs. 15 cases), swelling erosion (5 cases vs. 6 cases), bile reflux (2 cases vs. 3 cases) and positive pylorus spirobacteria (20 cases vs. 29 cases) were significantly lower in the observation group than those in the control group (allP < 0.05).Conclusion The therapeutic effects of Danggui Sini decoction for treatment of patients with chronic non-atrophic gastritis and TCM syndrome of spleen-stomach deficiency-cold are remarkable.

Strict measures to keep patients sleeping in face-up supine position, timely observation and treatment of complications should be important to ensure the success of the operation.

Anthocyanin biosynthesis is one of the thoroughly studied enzymatic pathways in biology, but little is known about the molecular mechanisms of its final stage: the transport of the anthocyanins into the vacuole. A clear picture of the dynamic trafficking of flavonoids is only now beginning to emerge. So far four different models have been proposed to explain the transport of anthocyanins from biosynthetic sites to the central vacuole, and four types of transporters have been found associated with the transport of anthocyanins: glutathione S-transferase, multidrug resistance-associated protein, multidrug and toxic compound extrusion, bilitranslocase-homologue. The functions of these proteins and related genes have also been studied. Although different models have been proposed, cellular and subcellular information is still lacking for reconciliation of different lines of evidence in various anthocyanin sequestration studies. According to the information available, through sequence analysis, gene expression analysis, subcellular positioning and complementation experiments, the function and location of these transporters can be explored, and the anthocyanin transport mechanism can be better understood.

Objective To explore a new method for lacrimal passage irrigation after laser dacryocystoplasty surgery. Method One-hundred patients (104 eyes), which underwent laser dacryocystoplasty surgery combined with lacrimal drainage tube indwelling, were divided into two groups. In Group A (50 patients, 52 eyes), lacrimal passage irrigation was performed by traditional No.5 needle. While in Group B (50 patients, 52 eyes), it was done by No.7 blunt round needle designed by the researchers. Lacrimal passage irrigation was performed three times, each at the 3rd day, 1 week and 1 month after surgery. The silicone tube was removed 3 months after surgery and the treatment was evaluated. Results The total effective rate was 64% (32/50) in Group A and 92%(46/50) in Group B. The difference was statistically significant (χ2=18.537, P < 0.01). Conclusions The No.7 blunt round needle showed better effect when used for lacrimal passage irrigation after laser dacryocystoplasty surgery. It could improve the efficiency of lacrimal passage irrigation, thus decreasing irrigation times and reducing psychological pressure for the patients, which is worthy of clinical application.

OBJECTIVE:To observe the efficacy and safety of Guizhi fuling capsule combined with mifepristone in treatment of uterine fibroids. METHODS:116 patients with uterine fibroids were randomly divided into control group and observation group. Control group was orally given Mifepristone tablet 25 mg,2 h before meal in the first day of menstrual period,once a day,for con-tinuous 10 d;observation group was additionally given Guizhi fuling capsule 3 pills in non-menstrual period,3 times a day. 3 months was regarded as a treatment course,it lasted 2 courses. Clinical efficacy,and E2,FSH,SHBG,uterine volume,menstrual blood volume,uterine fibroid volume and incidence of adverse reactions in 2 groups before and after treatment were observed. RE-SULTS:Total effective rate in observation group was significantly higher than control group,the difference was statistically signifi-cant(P<0.05). After treatment,the FSH,E2,uterine volume,menstrual blood volume and uterine fibroid volume in 2 groups were significantly lower than before,and observation group was lower than control group,the differences were statistically signifi-cant(P<0.05);but there were no significant difference in the SHBG and adverse reactions between 2 groups(P>0.05). CONCLU-SIONS:The clinical efficacy of Guizhi fuling capsule combined with mifepristone in treatment of uterine fibroids is more signifi-cant than mifepristone alone,with good safety.

Objective To investigate the respiratory pathogen distribution characteristics in children with acute respiratory disease(ARD).Methods Distribution of respiratory pathogen in 28 600 children with ARD,treated from January 2011 to December 2014 in this hospital,were analyzed.Results Among the 28 600 children,12 162 cases were pathogen positive,including 7 704 cases(63.34%) with single pathogen infection and 4 458 cases(36.66%) with more than two kinds of pathogens infection.Time,season,sex and age distribution of pathogen infection were with statistical difference(P<0.05).There was significant difference in infection rate of pathogens between different time(P<0.05).Infection rate of Mycoplasmal pneumonia(MP) was the highest,and the infection rate of MP and influenza B virus(IFB) increased year by year.Except Legionella pneumophila(LP),the season distribution of infection rate of MP,Coxiella burneti(COX),Chlamydia pneumoniae(CP),adenovirus(ADV),respiratory syncytial virus(RSV),influenza A virus(IFA),IFB and parainfluenza virus(PIVs) were with statistical difference(P<0.05).The infection rate of MP and IFB were higher in the whole year.Conclusion Distribution of respiratory pathogen in children with ARD might be related with the changes of gender,age and season.Detection of respiratory infection pathogen could be with guiding value for clinical diagnosis and drug selection.

[Objective] To analyze the image findings of MR enterography (MRE) and diffusion weighted imaging (DWI) in Crohn disease (CD) and to discuss the diagnostic value of MRI for evaluating the activity of CD.[Methods] 26 patients proved by clinical,imaging and pathological data were enrolled in this study.The intra-/extra-intestinal image features of CD were retrospectively analyzed,and the intestinal lesions were evaluated by MRE+DWI scoring system.The differences in image features of active and inactive CD were compared.[Results] 26 bowel segments were evaluated and included active (n =20) and inactive CD (n =6).The intestinal performance of CD included wall thickening,T2WI hyperintensity and hyperenhancement.The pathological changes of active CD were more serious when comparing with that of inactive CD.DWI showed hyperintensity in the affected bowel wall.ADC of active C D [(0.9 ± 0.2) × 10-3 mm2/s] was significantly lower than that of inactive CD [(1.5 ± 0.4)× 10-3 mm2/s] (P ＜ 0.001).Extra-enteric performance of active CD included comb sign,lymphadenectasis of mesentery,mesenteric exudation,fistula and abdominal abscess.[Conclusion] MRE combined with DWI can accurately assess CD activity and diagnose extra-enteric complications.
