ABSTRACT

Objective To investigate the infection status of Helicobacterpylori (HP) in the physical examination population and the contents of pepsinogen Ⅰ (PGⅠ),pepsinogen Ⅱ (PGⅡ) and gastrin-17 (G-17) in serumand the association with HP infection.Methods In this study,781 cases of physical examination were included.Serum HP antibody typing,PGl,PGⅡ and G-17 were measured by Helicobacter pylori antibody kit and enzyme-linked immunosorbent assay.The levels of PGⅠ,PGⅡ,PGⅠ/PGⅡ and G-17 were analyzed by SPSS22.0 analysis system,and the difference of HP infection rate between HP infection group and non-infected patients and different types of infection was analyzed.Analysis of the infection rate and the difference of each age group.Results There was no significant difference between the two groups (x2 =0.284,P=0.594),and there was significant difference between different age groups (x2 =8.523,P=0.014).The levels of PGⅠ,PGⅡ,PGR and G-17 in serum were statistically significant (Z=8.616~ 14.125,P=0.000) compared with those of HP positive and negative.There were significant differences in serum PGⅡ and PGR levels between HP Ⅰ type and HP Ⅱ type infection (Z=3.444,3.385,P=0.001).The levels of PGⅠ and PGⅡ in serum were significantly higher than those in other groups (Z=5.012,4.478,P=0.000).PGⅠ and PGⅡ were higher in women than in females (Z=0.444~0.941,P>0.05),with the increase of age,PGⅠ,PGⅡ and G-17 has an upward trend,while PGR showed a downward trend.Conclusion The level of serum PG was closely related to gender,age and HP infection,and was closely related to HP infection classification.The combination of HP antibody typing and serum PG and G-17 as a routine test of gastric function is of great significance in the screening and evaluation of early gastric diseases.

ABSTRACT

Objective To investigate the diagnostic value of the single detection and combined detection of Epstein-Barr virus (EBV) VCA-IgM ,aspartate transaminase (AST) and alanine transaminase (ALT) in EBV current infection .Methods The VCA-IgM positive simples tested by chemiluminescence from January to October 2016 were collected .EBV-DNA was detected by RT-PCR .AST and ALT were detected by using the enzyme rate method .Then samples were divided into the EBV-DNA positive group and EBV-DNA negative group .SPSS22 .0 was used for conducting the non-parametric test .Then each indicator was analyzed by the Logistic regression and receiver operating characteristic (ROC) curve .Results The levels of VCA-IgM ,AST and ALT in the EBV-DNA positive group were higher than those in the EBV-DNA negative group ,the difference was statistically significant (P<0 .05) . VCA-IgM ,AST and ALT showed a correlation with EBV-DNA (P<0 .05) .The areas under curve (AUC) of VCA-IgM ,AST and ALT single indicator detection curve were 0 .803(95% CI:0 .735 -0 .872) ,0 .788(95% CI:0 .708 -0 .868) ,and 0 .752(95% CI:0 .671-0 .832) ,respectively ;AUC of 3-indicator combined detection were 0 .830(95% CI:0 .765 -0 .896) ,which was high than AUC of each single indicator detection .Conclusion Among the indicators in EBV current infection ,VCA-IgM is of great diagnostic value ,and is superior to AST or ALT .Furthermore ,the combined detection of these three indicators is better than single indicator detection ,which contributes to the diagnosis and prevention of EBV infection and other complicating infection .

ABSTRACT

BACKGROUND: It has been reported that glass ionomer sealants have a poor wear resistance and low rupture strength that are easy to fall off on the occlusal surfaces. OBJECTIVE: To observe the effects of high-strength glass ionomer via the atraumatic restorative treatment (ART) on the pit and fissure of deciduous teeth in the young children. METHODS: A self-controlled method was used to compare ART glass ionomer-based pit and fissure seal on unilateral molars with resin sealant on the contralateral side in 89 children aged 3 years. RESULTS AND CONCLUSION: The retention rates of ART glass ionomer sealant after 6 and 18 months were 94.15% and 77.72%, respectively. At 6 months after treatment, ART gliass ionomer sealant was more caducous in mandibular second deciduous molars > mandibular first deciduous molars > maxillary second deciduous molars > maxillary first deciduous molars; at 18 months after treatment, the rank was mandibular second deciduous molars > maxillary second deciduous molars > mandibular first deciduous molars > maxillary first deciduous molars. The second deciduous molar of the lower mandible, but the caducous position of resin sealant was the second deciduous molar of the upper mandible. The caries prevalence rate of the deciduous teeth treated with ART glass ionomer sealant was significantly lower than that without sealant at 6 and 18 months (P < 0.01). These findings indicate that ART glass ionomer pit and fissure sealant is of a lower drop-out rate, easy to operate and of low cost with excellent caries-preventing effect.

ABSTRACT

BACKGROUND: Traditional glass ion sealant has a poor abradability and a low rupture strength. The sealant on the occlusal surfaces easily fell off, and is difficult to replace resin sealant. OBJECTIVE: To observe the effects of traditional resin sealant and atraumatic restorative treatment (ART) glass ionomer-based pit and fissure sealant for the young children. METHODS: Randomized comparison method was used to compare ART glass ionomer-based pit on molars of one side with resin sealant on the opposite side in 89 3-year-old children. RESULTS AND CONCLUSION: The retention rates of ART glass ionomer sealant after 6 and 18 months were significantly lower than those of resin sealant (P < 0.05). The caducous position of ART gliass ionomer sealant was the second deciduous molar of the lower mandible, but the caducous position of resin sealant was the second deciduous molar of the upper mandible. The secondary caries rate of ART glass ionomer sealant was significantly lower than that of resin sealant at 6 months. No significant difference was determined between groups at 18 months. These suggest that ART glass ionomer pit and fissure sealant has lower drop-out rate, simple operation and low cost with excellent caries-preventing effect. Since it is economically superior to resin sealant, the method is worth popularizing in caries-preventing projects.

ABSTRACT

Objective To investigate the relationship between obesity parameters and obstructive sleep apnea-hypopnea syndrome (OSAHS) in aircrew. Methods A questionnaire survey in aircrew members was performed. Outcome measurement included body height, body weight, neck circumference ( NC), waist circumference (WC), and body mass index (BMI). Those with snoring during sleep and/or Epworth sleepiness scale (ESS)score ≥ 9 were screened with pulse oxygen saturation test during overnight sleep. Those with oxygen saturation decrease index ≥ 10 times/h and suspected OSAHS were tested by polysomnography (PSG). The objects were then assigned to three groups: the OSAHS group,the snore group and the normal group. The relationship between obesity parameters and OSAHS was analyzed. Results There were 399 ( 37. 54% ) overweight, 36 ( 3. 39% ) obesity, 130 ( 12. 23% ) increased NC, and 354 (33.30%)increased WC in 1063 aircrew members (OSAHS group > snore group > normal group; P<O. 05). The mean value of BMI, NC and WC in the three groups were dittos. Multiple logistic regression analysis showed that overweight, obesity and increased WC were significantly associated with snoring (P <0.05) and snoring enlarged NC was significantly correlated with OSAHS (P< 0.05). Conclusion Increased BMI, NC and WC may be risk factors of OSAHS among aircrew. Effective prevention and treatment of OSAHS should be needed.

ABSTRACT

The exposure of lead in environment has caused a major public health problem all over the globe.Because of rapid industrialization and constant existence of lead in environment,it is necessary to screen,monitor and intervene in the content of lead of human body during a long time.The toxical and harmful influence of lead on human body,especially on children are expounded.The content index of lead in the body set by international and national standards as well as its evaluation basis are included.The most frequently used testing method of blood lead is also described: atomic absorption spectrometry and its operative process.
