ABSTRACT
OBJECTIVE To systematically evaluate the safety of paroxetine in the treatment of pregnant patients with depression in the second and third trimesters of pregnancy， and provide reference for rational clinical use of it. METHODS Retrieved from Cochrane Library， PubMed， Embase， VIP， CNKI， Wanfang database and SinoMed database， by manual search， randomized controlled studies or observational studies were collected on depression patients who were given paroxetine vs. selective serotonin reuptake inhibitor （SSRI） in the second and third trimesters of pregnancy during the inception to Aug. 2022. Methodological qualities of the included studies were assessed by Cochrane Handbook 5.1.0 or Newcastle-Ottawa Scale （NOS）. Meta-analysis was performed with RevMan 5.4.1 software. RESULTS Finally， 9 observational studies were included， and all included studies were of high quality in NOS scale. Meta-analysis was performed on 8 cohort studies. Meta-analysis showed that the total incidence of adverse pregnancy outcomes of mothers and infants [RR＝0.99， 95%CI（0.89，1.10），P＝0.87]， total incidence of maternal adverse pregnancy outcomes [RR＝0.98， 95%CI （0.87，1.10）， P＝0.69] and premature birth [RR＝0.89， 95%CI （0.43， 1.83）， P＝0.75] in the second and third trimesters of pregnancy were lower than that with other SSRI， without statistical significance. The incidence of neonatal complications with paroxetine in the second and third trimesters of pregnancy was higher than that with other SSRI， but the difference was not statistically significant [RR＝1.02， 95%CI （0.82，1.29）， P＝0.84]. One study reported that the incidence of neonatal pulmonary hypertension in paroxetine group was higher than that in other SSRI group （0.4% vs. 0.3%）. CONCLUSIONS The safety of peroxetine in the second and third trimesters of pregnancy is comparable with that of other SSRI， but it is necessary to be alert to the occurrence of neonatal pulmonary hypertension.
ABSTRACT
OBJECTIVE: To study the compatibility of inner surface of anatomy bottle and Caffeine citrate injection.METHODS: After treated with high temperature (60 ℃, 10 days), light (5 000 Lx, 10 days), freezing and thawing (2 days for freezing at -18 ℃ and 2 days for thawing at 40 ℃ as a circulation, and repeat for 3 times), sterilizing (121 ℃, 2 h), Caffeine citrate injection packed in anatomy bottle was tested in respects of pH value, insoluble particle, glass stripping tendency before test and under the above conditions. The contents of arsenic, cadmium, lead, cobalt, manganese, vanadium, copper, lithium, barium, chromium, antimony, aluminum, boron, calcium, iron, potassium, magnesium, silicon and titanium that may dissolve by inner surface of anatomy bottle were tested by ICP method, and compared with analysis evaluation threshold (AET) of each element. RESULTS: Before the test, under high temperature, light, freezing and thawing, sterilization, and pH values of Caffeine citrate injection installed with ampoule were 4. 58, 4. 60, 4. 61, 4. 58, 4. 58. The insoluble particles were all in line with 0903 provisions stated in (four) general provisions of Chinese Pharmacopoeia (2015 edition). The inner surface of ampoule bottle glass had no stripping tendency. The arsenic, cadmium, lead, cobalt, manganese, vanadium, copper, lithium, barium, chromium, antimony, iron, magnesium and titanium were not detected in caffeine citrate injection, and the contents of aluminum, boron, calcium, potassium and silicon were far below its AET value. CONCLUSIONS: Caffeine citrate injection has no effect on inner surface of ampoule bottle.
ABSTRACT
Objective To evaluate the value of acoustic radiation force impulse (ARFI) elastography in assessment of nonalcoholic fatty liver disease (NAFLD) and hepatic fibrosis in rats.Methods Models with various degrees of NAFLD severity were conducted in 110 rats by feeding high fat emulsion.The right liver lobe of rat models were processed and embedded in a fabricated gelatin solution to measure the shear wave velocity (SWV) by ARFI.And the other liver lobes were used for histologic assessment.Based on NAFLD activity score (NAS),the final pathologic NAFLD diagnosis were considered as normal group (NAS=0),simple steatosis (SS) group (1≤NAS≤2),borderline (3≤NAS≤4) group and nonalcoholic steatohepatitis (NASH) group (NAS≥5).The diagnostic accuracy of the SWV parameters in evaluating NAFLD severity and fibrosis stages was studied using ROC curves.Results The difference of SWV values among normal group,SS group,borderline group and NASH group was statistically significant (F=31.53,P＜0.001).Taking SWV≥ 2.54 m/s as the diagnostic standard to differentiate normal rats from rats with SS,and SWV≥2.90 m/s to differentiate SS from NASH in rats,the area under ROC curve (AUC) was 0.922 (95％CI [0.871,0.973],P＜0.001) and 0.882 (95％ CI [0.807,0.956],P＜0.001) respectively.The sensitivity and specificity were 93.5 ％ and 100 ％ for differentiating normal and SS groups,83.3 ％ and 84.2 ％ for differentiating SS and NASH groups.Taking SWV≥3.48 m/s as cutoff to predict fibrosis (≥F2 stage),the AUC was 0.963 (95％CI [0.909,1.000],P＜0.001),the sensitivity was 92.9％ and the specificity was 97.6％.Taking SWV≥3.61 m/s as cutoff to predict severe fibrosis (≥F3 stage),the AUC was 0.997 (95％CI [0.990,1.000],P＜0.001),sensitivity was 100％ and specificity was 98.9％.The same high validity was maintained as in the prediction of cirrhosis (F4 stage) with the cutoff as SWV≥4.50 m/s,and the AUC was 0.993 (95％CI [0.982,1.000],P＜0.001),the sensitivity was 100 ％ and the specificity was 96.8％.Conclusion ARFI elastography is a promising method for differentiating the different severity of NAFLD and staging the degree of hepatic fibrosis with NAFLD in rat models.
ABSTRACT
