Objective To study the incidences of falls in patients with Parkinson's disease and analyze the related factors.Methods The clinic data of 100 Parkinson's patients were retrospectively analyzed to investigate the fall incidence and the related factors.Results The fall incidence was 46.0%during hospitalization in the patients with Parkinson's disease.The single factor analysis showed that the falls incidence were higher in male patients,dizziness from drug factors,a history of falls and non-presence of their families during hospitalization than those in the non-fall group(P<0.05).Logistic regression analysis showed that male patients,dizziness from drug factors,a history of falls and non-presence of their families during hospitalization were risk factors for Parkinson's patients during hospitalization.(all P<0.05). Conclusions The high risk factors for the falls in Parkinson's patients include male patients,dizziness from drug factors,a history of falls and non-presence of their families during hospitalization.Therefore,the assessment of the risk factors for falls should be done so as to carry out fall factors control and fall risks classification management for the purpose of reducing falls.

To explore the clinical application and value of small incisions in the treatment of benign thyroid diseases with endoscopic assistance.A total of 57 cases with thyroid nodules were operated under the assistance of ultrasonic scalpel and endoscope with the lifting-up of special instrument and small neck incisions.However one malignant case was converted iuto open surgery according to frozen sections.The other 56 cases were successfully operated.The mean operative duration was 42 min and postoperative stay 2 -3 days.All incisions achieved primary healing and the length range was 1.5 - 3.5 cm.Except for transient hoarseness in 1 case,there was no such complications as choking,lip paralysis or hemorrhage,etc.All were discharged uneventfully.This surgical approach shall be recommended for its merits of miniinvasiveness,less hemorrhage,fewer complications and wider applications.

Objective:To study the antimicrobial properties of CaO/ZnO core-shell nanoparticles.Methods:The CaO/ZnO core-shell nanoparticles were prepared via precipitation method.The pH and calcium ion release from the samples which composed of eugenol and nanoparticles were examined respectively.The form of the particles was observed under electron microscope,the ions were analysed by inductively coupled plasma(ICP).The antibacterial activities against Streptococcus mutans,Enterococcus faecalis,Escherichia coli and Staphylococcus aureus were evaluated by agar diffusion test (ADT).Results:CaO/ZnO core-shell nanoparticles were spherical with core-shell structure and with the diameter of 80-90 nm.The calcium ion release and pH were gradually increasing from the nanoparticles in PBS.The antibacterial activity of CaO/ZnO core-shell nanoparticles-eugenol was significantly greater than that of iRoot SP and zinc oxide-eugenol sealer(P<0.01).Conclusion:CaO/ZnO core-shell nanoparticles possess antibacterial activity.

Objective To explore the clinical efficacy and safety of betaquiline fumarate tablets in the treatment of multi drug resistant pulmonary tuberculosis.Methods Patients with multidrug-resistant tuberculosis(MDR-TB)admitted to the Third People's Hospital of Kunming from March 2019 to September 2022 were selected as the research objects.They were divided into two groups by random number table method.The observation group(n = 93)received anti tuberculosis treatment with a regimen containing bedaquiline fumarate tablets,while the control group(n = 90)received anti tuberculosis treatment with a regimen without bedaquiline fumarate tablets.The lesion absorption rate,sputum negative conversion rate,cavity reduction rate,treatment efficiency,and adverse drug reactions during treatment were collected at the end of 24 weeks.Results At the end of the 24th week of treatment,the differences between the observation group and the control group in the rates of lesion absorption rate(85.7%,63.3%),negative conversion of sputum smears(89.7%,71.4%),negative conversion of sputum cultures(82.1%,68.6%),cavity shrinkage rate(88.2%,69.4%),and total treatment efficacy(81.9%,60.2%)were statistically significant(P<0.05).The difference in the incidence of adverse drug reactions between the observation group and the control group(69.9%and 83.4%)was statistically significant(P<0.05),but the difference in the severity of adverse reactions was not statistically significant(P>0.05).Conclusion The regimen containing betaquiline fumarate tablets has good efficacy and is safe in the treatment of multidrug-resistant pulmonary tuberculosis.

Objective: To investigate the association between APOB gene R532W polymorphism and the risk of coronary heart disease (CHD) in patients without lipid-lowering treatment and to analyze the interactions between the variation of R532W and different risk factors of CHD. Methods: CHD and non-CHD were diagnosed according to coronary artery angiography (CAG) and/or coronary computed tomography angiogram (CTA) results, as well as clinical features. Blood samples from 771 CHD patients and 772 age- and sex-matched non-CHD controls, who never accepted any lipid-lowering treatments, were collected. R532W was genotyped by HumanExome BeadChip at BGI and strict quality control was made. Firstly, the association between R532W polymorphism and the risk of CHD in 3 genetic models (GA+ AA vs.GG, AA vs. GG+ GA, AA vs. GA vs. GG) after adjusting confounding factors was explored. Then, the interactions between the variation of this loci and risk factors related to CHD were investigated. Results: (1) Total cholesterol (TC) levels were significantly lower in AA genotype than in GA genotype in the total cohort and non-CHD controls, but was similar among the 3 genotypes in CHD patients. (2) R532W GG, GA and AA distribution was 80.7%, 18.2% and 1.2% in CHD patients, and 74.6%, 23.8% and 1.6% in non-CHD controls (P<0.05). (3) R532 polymorphism was related to the incidence of CHD in the dominant model, and A-allele carriers were related to about 35% reduced risk of CHD (OR=0.653, 95% CI 0.502-0.849, P=0.001) after adjusting for confounding factors. (4) R532W polymorphism had positive interactions with hypertension (1.452) and smoke (1.077), while negative interaction with diabetes (0.553) in the occurrence of CHD. Conclusions APOB gene R532W polymorphism is related to TC levels in Chinese north Han population. A-allele carries of R532W loci is linked with reduced risk of CHD in the absence of lipid-lowering treatment. R532W polymorphism has a positive additive interaction with hypertension and smoke, while a negative additive interaction with diabetes mellitus in the occurrence of CHD.

FimA has been characterized as an important virulence factor for Porphyromonas gingivalis (Pg). These structures play a major role in the mechanisms of adhesion and invasion of Pg to host cells, and can induce cellular activation and cytokines release. FimA can also promote biofilm formation and induce immuno-inflammatory response of host cells. Many studies have characterized FimA to be associated with periodontitis and cardiovascular disease. Pg strains are classified into six types based on divergent nucleotide sequences of the fimA gene (types Ⅰ、Ⅰb、Ⅱ、Ⅲ、Ⅳ andⅤ). The expression of fimbriae is regulated by the fimA gene, which may be the key factor that leads to virulence diversities of Pg, At present, the research on the pathogenesis of FimA mainly focuses on periodontitis and atherosclerosis, which is of great significance for the prevention and treatment of diseases. This paper reviewed the pathogenic effect of FimA in the development of above mentioned two diseases and its application in the prevention.
