2.Role of probiotics against the infection of parasites in the intestine
Chinese Journal of Zoonoses 2017;33(5):459-464
Probiotics have been defined as living microorganisms exert beneficial effects on the health of the host,which can be effective in the treatment of gastrointestinal tract,respiratory tract infections and allergic diseases.Although it is currently mainly used for the treatment of bacterial and viral infections,there are also studies have shown that probiotics have inhibitory effects on parasites infection.Therefore,probiotics will provide a new way for the prevention and treatment of parasites.
3.Discussion of Inflexion Question in Course of Measuring Surface Tension Coefficient by Force Sensor
Chinese Medical Equipment Journal 1989;0(01):-
Objective To discuss the inflexion question in the course of measuring surface tension coefficient.Methods Metal frames with different lengths,radials and metal cylinders with different inside & outside radials were used to measure the inflexion.Results The inflexion appeared in the course of measuring surface tension coefficient by using force sensor and the inflexion changed with the different radials and lengths of the metal frames.Conclusion The thickness and bending of the fluid membrane results in the change of inflexion,and the inflexion can be avoided with the length and radial chosen properly.

Objective To explore the reporting process of our health risk warning system and its long-term effectiveness.Methods A total of 1 168 individuals who were identified as higher risk populations from July 2011 to June 2012 in our Health Mangement Center were served as the control group,and another 973 adults who were identified as higher risk individuals from July 2012 to May 2013 were assigned to the study group.Diagnosis and treatment were based on our health risk reporting process and follow-up system.Paired t test and paired contingency table x2 test were used for data analysis.Results The rate of follow-up (97% vs 100%,x2=30.503,P<0.05),consultation (83.48% vs 93.63%,x2=52.142,P< 0.05),mean treatment time ((3.0±0.5) vs (1.5±0.5) d,t=69.12,P<0.05) and patient satisfaction (87.84% vs 96.20%,x2=48.361,P<0.05) were significantly different between the two groups,although no statistically significant difference of incidence of adverse events was found (0.26% vs 0.10%,x2 =0.102,P>0.05).Conclusion Our health risk warning system may reduce the time for physical examination and improve disease diagnosis level and patients' satisfaction.Moreover,our health manatement system and health service quality should further be improved in practice.

The influenza A virus (IAV) belongs to the family Influenza Virus and subfamily Orthomyxoviridae. The IAV can cause acute infections of the lower respiratory in human and animals. Recently, many studies have been performed to reveal the lung CD4+ T cells, CD8+ T cells and Tregs via multiple effector and regulatory mechanisms to against IAV. In this paper, we review the state of progress with regards to various strategies of IAV escape from T cell responses, T cells and innate T cells immunity against influenza virus, which will provide a useful reference tool for future related reseach.

Objective To investigate blood level of triglyceride(TG)in community residents of urban and rural Beijing.Methods A total of 10 054 community residents were recruited by cluster samphng for investigation using questionnaire,as well as physical examinations and fasting plasma TG determination for diagnosing hypertriglyceridemia,during June to August,2007.Results Median of plasma level of TG of the participants was 1.17 mmol/L,ranging(0.81-1.78)mmoVL Totally,1234 people were diagnosed as borderline hypertriglyceridemia and 15 12 as hypertriglycefidemia.with prevalence of 12.27%and 15.04%,respectively.There was no significant difference in plasma level ofTG between men andwomen[1.16(0.80-1.84)mmol/L vs.1.18(0.81-1.75)mmol/L,P:0.187].Age-adjusted prevalence of borderline hypertriglyceridemia and hypertriglyeeridemia was higher in men than those in women(11.60% vs.10.90%and 20.32% vs.10.88%,respectively),and the same results were obrained in those less than 50 years old,however,reveraw outcomes were got in those more than 50 years old.Plasma level of TG,as well as prevalence of hypertriglyceridemia,were higher in those living in urban areas than those in rural areas[1.31(0.89-1.95)mmol/L vs.1.05(0.73-1.58)mmol/L].Awareness,proportion of people with hyperglycefidemia under treatment and proportion of those with TG under coutrol were 13.95%.35.92%and 38.51%,respectively.Standardized prevalence of borderline hyperglycefidemia and hyperglycefidemia were higher in those with coronary heart disease than those without it(24.79% vs.11.22%and 25.31% vs.15.35%,respectively).Conclusions Awareness,proportion of treatment and proportion of those under control for hyperglyceridemia were all lower in community residents of Beijing.Education and monitoring on hyperglyeeridemia should especially be strengthened for urban residents,women aged more than 50 years,and these with coronary heart disease.

Total 1 500 subjects aged over 60 years were selected from 10 community health service centers with cluster sampling method.A questionnaire survey and physical examination were performed in all subjects.Sixty five patients with chronic heart failure were detected.The questionnaire showed that 77.6% (38/49)patients were diagnosed in tertiary hospitals,and 12.2% (6/49) were diagnosed in community hospitals.When heart failure occurred,most patients (37.7%,20/53) chose to take a taxi to the tertiary hospital directly,and less patients (17.0%,9/53)contacted community doctors.When a heart attack happened,68.8% (33/48)of the patients could reach the hospital within 30 min,and 55.3% (26/47) within 60 min.45.7% (21/46) elderly patients were hospitalized for heart failure once a year;31.1% (14/45) were in hospital for less than 10 d each time.46.0% (23/50) heart failure patients had received health education and 40.0% (16/40) had taken drugs under supervision;the majority health educators were community doctors and majority supervisors were family members.The results suggest that the confirmed diagnosis and treatment of heart failure patients still rely on tertiary hospitals,community health institutions play an important role in health education and management of heart failure patients outside hospitals.But the utilization of community health services is still not enough in community health service centers.

To explore the clinical manifestation of lymphomatoid granulomatosis (LG) and the early diagnosis. Retrospective analyses of the clinical features of LG and pathology features by open lung bio-psies were conducted. The patient was a 42-year-old female with irregular fever,and her chest X-ray and computed tomography showed nodules with cavity and pleural effusion. Open lung biopsy proved LG. LG is seldom seen in clinic. Open lung biopsy is very important for pathology diagnosis. Early diagnosis and treatment are the key to improving survival in these patients. The therapeutic effect is good.

OBJECTIVE To explore the clinical features for pulmonary cryptococcosis due to Cryptococcus neoformans,and to improve diagnosis and treatment of the disease.METHODS The clinical features of inpatients with pulmonary cryptococcosis were studied retrospectively.RESULTS There were nine cases of pulmonary cryptococcosis from 1999 to 2006 of all inpatients in our hospital.Mals 5(56%),females 4(44%),and 3 cases(33%) were more than 60 years old.Three cases(33%) were immunocompromised hosts,6 cases(67%) had clinical symptoms.Chest X-ray and computed tomography were various included single or poly patching or nodule shadows,some had cavity(33%) and some had pleural effusions(22%).Six cases had positive results with serum cryptococcal antigen test.All nine patients were treated with fluconazole and improved or cured.CONCLUSIONS Pulmonary cryptococcosis is seldom seen in clinic,it can be observed in humans with normal immune responses or immunocompromised hosts and has no significant clinic manifestations,serum cryptococcal antigen test is helpful,definitive diagnosis needs early lung biopsy.The therapeutic effect is well.
