ABSTRACT
Background:Chronic atrophic gastritis(CAG)is a common disease of digestive system and is a precancerous lesion of the intestinal type gastric cancer. Serum pepsinogens(PGs)and gastrin 17(G17)are biological markers of gastric mucosal lesions,which have a prominent role in diagnosis of CAG and screening of early gastric cancer. Aims:To study the correlation of serum PGs and G17 with age in patients with CAG. Methods:A total of 582 CAG patients admitted from Jan. 2016 to Sep. 2017 at the Baoding First Central Hospital were enrolled. The levels of serum PGⅠ,PGⅡ and G17 were determined by ELISA,and the PGⅠ/ PGⅡ ratio(PGR)was calculated. The correlations of these indices with the clinical data of CAG patients were analyzed. Results:The levels of serum PGⅠ and PGⅡ were increased with age(P<0.01),and the levels of PGR and G17 were decreased with age(P <0.05). Spearman rank correlation coefficient analysis showed that the levels of PGⅠ and PGⅡ were positively correlated with age(rs=0.374,P<0.01;rs=0.559, P<0.01),and the levels of PGR and G17 were negatively correlated with age(rs= -0.649,P<0.01;rs= -0.141, P<0.05). Conclusions:The levels of serum PGⅠ,PGⅡand G17 in patients with CAG were correlated with age. When serum PGs and G17 are used as serological indicators for diagnosis of CAG and screening of early gastric cancer,the impact of age on these indices should be taken into account.
ABSTRACT
OBJECTIVE:To study the effect of paroxetine combined with low dose of olanzapine on sleep process and architec-ture of depression patients with insomnia. METHODS:84 depression patients with insomnia were randomly divided into control group and observation group. Control group was given 20 mg Paroxetine tablet,once every morning;observation group was addi-tionally given 2.5 mg Olanzapine tablet,once before going to bed. Sleep quality [Pittsburgh Sleep Quality Index(PSQI)],depres-sion scores [Hamilton Depression Scale (HAMD)],sleep process [sleep latency (SL),awakening times (AT),the actual total sleep time (TST),sleep efficiency (SE),rapid eye movement (REM) sleep latency (RL)] and sleep architecture [sleep stage 1 (S1),2(S2),3(S3)and the proportion of REM to sleep] in 2 groups before and 3,6 months after treatment and the incidence of adverse reactions(ADR)were observed. RESULTS:After treatment,PSQI and HAMD scores in 2 groups were significantly lower than before,and gradually decreased by time,and observation group was lower than control group;TST in observation group was significantly higher than before and control group,S1 in observation group was significantly lower than before,SE,S3 and REM in 2 groups were significantly higher than before,and observation group was higher than control group,SL,AT,RL and S2 were significantly lower than before,and observation group was lower than control group,the differences were statistically significant (P<0.05). There were no obvious ADR in 2 groups. CONCLUSIONS:Paroxetine combined with low dose of olanzapine can sig-nificantly relieve depression,optimize sleep process and sleep architecture,then impove sleep quality.
