Objective:To evaluate the preventing effects of 4 anti-caries preparations on enamel demineralization in fixed appliance orthodontic treatment.Methods:200 patients treated with fixed appliance were included and randomly divided into 4 groups (n =50),the teeth were treated with fluoride-containing toothpaste,fluoride varnish,fluoride free toothpaste and casein phosphopeptide-amorphous calcium phoaphate(CPP-ACP) respectively.The enamel decalcification incidence was calculated after orthodontic treatment.Results:The incidence of enamel decalcification calculated by tooth number was 16.3％ in fluoride-containing toothpaste group,9.3％ in fluoride varnish group,21.9％ in fluoride free toothpaste and 8.5％ in CPP-ACP group(among groups,P ＜0.05;between CPP-ACP and fluoride varnish,P ＞ 0.05).Conclusion:Fluoride containing preparation can prevent the enamel demineralization during the fixed appliance orthodontic treatment,CPP-ACP and fluoride varnish are more effective.

OBJECTIVE:To investigate clinical efficacy and safety of different dosages of bromocriptine in the treatment pro-lactinoma,and its effects on serum prolactin(PRL)and tumor volume. METHODS:A total of 60 patients with prolactinoma were selected from our hospital during Jan.-Dec. 2015 as research objects,and then divided into group A and B according to random number table,with 30 cases in each group. Both groups were given Bromocriptine mesilate tablets orally during meal. Group A was given medicine with initial dose of 2.5 mg/d,increasing to 3.75 mg/d 3 d later,increasing by 2.5 mg every week after 2-3 d,and then recovering to 3.75 mg/d till serum PRL level had been controlled. Group B was given medicine with initial dose of 1.25 mg/d, increasing to 2.5 mg/d 3 d later,increasing by 1.25-2.5 mg every week after 2-3 d,and then recovering to 2.5 mg/d till serum PRL level recovered to normal. Both groups were treated for consecutive 3 months. Clinical efficacies as well as serum level of PRL and tumor size were observed in 2 groups,and the occurrence of ADR was recorded. RESULTS:The total response rate of group A (83.33％) was higher than that of group B (66.67％),without statistical significance (P>0.05). Before treatment,there was no statistical significance in serum level of PRL and tumor size between 2 groups (P>0.05). After 1,2 months of treatment,serum levels of PRL in 2 groups were decreased significantly,and the group A was significantly lower than the group B,with statistical significance(P<0.05). After 3 months of treatment,serum levels of PRL in 2 groups were decreased significantly compared to be-fore treatment,but there was no statistical significance between 2 groups(P>0.05). After treatment,tumor size of 2 groups were decreased significantly,and large adenoma and giant adenoma size in group A were significantly smaller than group B,with statisti-cal significance(P<0.05). There was no statistical significance in microadenoma size between group A and B(P>0.05). The inci-dence of ADR in group A(12 cases,40.00％)was significantly higher than group B(5 cases,16.67％),with statistical signifi-cance(P<0.05). CONCLUSIONS:Increasing dosages of bromocriptine no significant influence on therapeutic effect of prolactino-ma,but it can shorten the time of serum PRL level back to normal,and reduce the tumor size. The incidence of adverse reactions in-crease with the dosage.

Antihistamines,a group of drugs most commonly used for the treatment of allergic diseases in dermatology,exert favorable efficacy and are well tolerated in most people.Due to their wide application,the safety of medication is particularly important.When they are used in some special populations with allergic diseases,such as children,pregnant and lactating women,the elderly and people with hepatic or renal insufficiency,their pharmacodynamics,metabolic characteristics and interactions with other drugs should be fully considered,and profits of medication and potential adverse effects should be well weighed before choosing relatively safe antihistamines.In addition,decreasing the routine dose or prolonging intervals between the administration of antihistamines may also be attempted to achieve maximum safety.

As important adhesion molecule on cell surface,integrin is a kind of important receptor family. It′s im- portant role is to mediate intercellular adhesion and adhesion between cells and extracellular matrix,also regulate proliferation,differentiation,migration of cells and tissue remodeling,and plays an important role in maintaining cellular form and growth.The present article made a short review about research progress of integrin β1 effect in cardiovascular diseases in recent years.

Partial immunoactivities of peptidoglycan(PG)isolated from lactic acid bacteria were investigated.PG isolated from strain Z8 and Z17 of lactic acid bacteria respectively,had similar immunoactivities.The phagocytic function of M?(macrophage)increased markedly and serum lysozyme activity was significantly enhanced by injection of PG-extracts on mice.Investigation of immuno-enhancing effects of PG on vaccine of Newcastle disease in chickens showed that the hemagglutination inhibition levels of PG were higher than that of the control and the level was maintained for a longer time as compared to the control.

ObjectiveTo probe into the maternal care utilization by minority women, for the purpose of policy recommendations on better maternal care in minority areas. MethodsA combination of stratified random sampling and typical sampling was made on 445 married women of reproductive age in six counties in Yunnan, Guizhou, Qinghai and Tibet provinces, a field survey on their utilization of maternal care services. ResultsTheir average prenatal detection rate is 78.24％, a level lower than the national rural average of 93.7％ and grade-4 rural average of 81.2％ in 2008; their post partook rate is 30.7％, lower than the national rural average of 54.3％ and grade-4 rural average of 58.9％ in the same period; their average coverage rate is 52.18％, a level lower than the national rural average of 87.1％and grade-4 rural average of 64.3％ in 2008. ConclusionThe maternal care utilization is found to be low for women in minority areas. Effective solutions are expected for payment of indirect expenditure of hospital delivery; better health education for enhancing health knowledge and health awareness of minority women; effective incentive mechanism for village doctors, consolidating the base of the three-level healthcare network.

Many microbial pathogens,including those responsible for major enteric infections,exploit oligosaccharides that are displayed on the surface of host cells as receptors for toxins and adhesins. Blocking crucial ligand receptor interactions is therefore a promising therapeutic strategy. One approach is to express molecular mimics of host receptors on the surface of harmless recombinant bacteria that can survive in the gut. These recombinant probiotics bind bacterial toxins in the gut lumen with very high avidity,thereby preventing disease.

Fermentation property and kinetic analysis of the inhibition of in vitro growth of pathogenic Escherichia coli K88, O138 by Lactobacillus intestinalis isolated from porcine intestine mucus were investi-gated. The results of fermentation showed that L1 result in a pH of 3.90 within 12 h and a large amount of lactic acid production, with the concentration of 104.08 mmol/L. Kinetic analysis of the antibacterial activity of L1 metabolic product toward K88, O138 showed that CFUS display strong antibacterial activity toward K88, O138; the antibacterial activity of L1 CFUS was higher than the lactic acid control samples and was mainly due to the production of lactic acid; K88, O138 had the tolerance property toward pH 4.5.

This paper reports 20 patients with cryptococcal meningitis,which were misdiagnosed before anti-fungal therapy,and the majority of them was diagnosed as tuberculous meningitis or viral meningitis.These patients were treated either with amphotericin B or fluconazale alone,or in combina- tion with flucytosine respectively,of the 15 patients could be evaluated,10 were cured(66.7%),2 im- proved(13.3%),3 died(20%),1 relapsed(10%).The mortality rate among the under age group and the aged group was significantly higher than that of the adult group(71.4% vs 23%).It is the authors' experience that in the early stage intrathecal amphotericin B combines with intravenous fluoconazole and changes to oral fluconazole or itraconazole in the later stage may be a valuable approach for cryptococcal meningitis.

Objective To investigate the expression of snrvivin,an anti-apoptosis gene,in breast cancer tissues and its relationship with clinical parameters of breast cancer patients.To investigate the role of survivin in oncogenesis of breast cancer and its relation with prognosis of breast cancer.Methods Western blot was conducted to detect survivin expression in cancerous tissues and adjacent tissues of 50 breast cancer patients.20 normal breast tissue samples were used as control.Results Survivin was expressed in 38 of the 50 breast cancer tissues (76.0%)and in 11 of 50 breast adjacent normal tissues(22.0%)while no expression was found in normal tissues.The positive protein expression of survivin was related to axillary lymph node metastasis of breast cancer while it was not related to expression of PR,ER,Her-2 or ages of patients.Conclusion Survivin may play a role in breast tumorigenesis and is an important predictive parameter in breast cancer patients.
