ABSTRACT
OBJECTIVE To compare the efficacy and safety of parecoxib and ketorolac tromethamine for perioperative analgesia， and to provide evidence-based reference for clinical drug use. METHODS Retrieved from PubMed， Embase， the Cochrane Library， CNKI， VIP， Wanfang Data， Baidu and Google， randomized controlled trials （RCT） about parecoxib （trial group） versus ketorolac tromethamine （control group） for perioperative analgesia were collected from the inception to Jun. 17th， 2022. After screening the literature and extracting the data， the quality of the included literature was evaluated using the bias risk assessment tool recommended by Cochrane system evaluator manual 5.1.0. Meta-analysis， sensitivity analysis and publication bias analysis were performed with RevMan 5.4 software. RESULTS A total of 12 RCTs were included， with 1 118 patients. Meta- analysis results showed that at the time of administration before anesthesia induction， there was no statistically significant difference between the 2 groups in visual analogue scale （VAS） [MD＝－0.16， 95%CI （－0.41， 0.09）， P＝0.20]， numerical rating scale （NRS） [MD＝0.01， 95%CI （－0.36， 0.38）， P＝0.97]， postoperative bleeding [MD＝0.15， 95%CI （－0.63， 0.93）， P＝0.71]， and consumption of opioid analgesics [MD＝0.12， 95%CI （－0.77， 1.01）， P＝0.79]. At the time of postoperative administration， VAS and bleeding volume at 48 h after operation of trial group were significantly lower than control group （P＜0.05）. The results of subgroup analysis by different com assessment time points showed that the VAS of patients in trial group at 0 h after operation were significantly lower than control group at the time of administration before anesthesia induction； at the time of postoperative administration， VAS of patients in the trial group at 12 h and 48 h after operation were significantly lower than control group （P＜0.05）. There was no statistical significance in the incidence of ADR between 2 groups [RR＝0.93，95%CI （0.78，1.11），P＝0.43]. The results of subgroup analysis according to different types of adverse reactions showed that the incidence of nausea and vomiting of trial group was significantly lower than control group， and the incidence of other adverse reactions was significantly higher than control group （P＜0.05）. Results of sensitivity analysis showed that study results were stable and reliable. Results of publication bias analysis showed that there was great possibility of publication bias in this study. CONCLUSIONS The efficacy of parecoxib is equivalent to that of ketorolac tromethamine for perioperative analgesia before operation； at the time of administration after operation， parecoxib has better analgesic effect and less postoperative bleeding； the incidence of nausea and vomiting caused by parecoxib is lower at any time of administration.
ABSTRACT
OBJECTIVE: To evaluate the economics of pharmaceutical care for pediatric inpatients provided by pediatric clinical pharmacists. METHODS: The cost-benefit analysis method was adopted. Randomized controlled trial data about pediatric clinical pharmacists intervening in drug treatment of pediatric inpatients were collected. The research objects were 0-18 years old children who were hospitalized for respiratory system disease, nervous system disease and digestive system disease in a hospital. Trial group additionally received pharmaceutical care provided by pediatric clinical pharmacists on the basis of routine medical service, and control group only received routine medical service. Cost indexes were clinical pharmaceutical care cost, and benefit indexes were the decrease of hospitalization cost and drug cost. Benefit-cost ratio was calculated in 2 groups, and sensitivity analysis was also conducted. RESULTS: Compared with control group, hospitalization cost and drug cost of trial group decreased by 30. 0％ and 33. 7％; clinical pharmaceutical care cost was 184. 1 yuan/person; benefit-cost ratio were 9. 45 and 4. 61 (both higher than 1), with economics. The results of cost-benefit analysis were supported by sensitivity analysis. CONCLUSIONS: The pediatric clinical pharmacists providing pharmaceutical care for pediatric inpatients shows active economic effects.
ABSTRACT
Objective@#To further understand the interaction protein spectrum of heterogeneous ribonucleoprotein AB (hnRNP AB), and to investigate their clinical significance in hepatocellular carcinoma (HCC).@*Methods@#We carried out mass spectrometry to reveal the specific peptides of KRAB-associated protein 1 (Kap1) and hnRNPAB, and verified their interaction by immunocoprecipitation and western blotting. Expression of hnRNPAB/Kap1 proteins were detected by immunohistochemical staining in the tissue microarrays. Categorical data were analyzed by the chi square test or Fisher exact test; enumeration data between groups were compared using Student t-test or Wilcocon signed rank test; the cumulative recurrence and survival rates were evaluated using the Kaplan-Meier method and the differences were assessed using the log-rank test.@*Results@#We identified Kap1 as a molecular partner for hnRNPAB in HCCLM3 cells and HepG2 cells as well. We found that the 5-year survival rate of the Kap1high patients was significantly lower than the survival rate of those of the Kap1low group (36% vs 59% , HR = 1.67, P < 0.001). Similarly, Kap1high HCC patients had the poorest prognosis at 5-years, with higher cumulative recurrence rate than Kap1low patients (72% vs 54%, HR = 1.66, P = 0.001). Univariate and Multivariate analyses revealed that hnRNPAB /Kap1 alone (HR = 1.35 /1.28, P = 0.001) or in combination with Kap1 (HR =1.24 /1.27, P < 0.05) were independent prognostic indicators for overall survival and time to recurrence.@*Conclusion@#In HCC cells, hnRNPAB and Kap1 form protein complexes. The expression levels of hnRNPAB alone or in combination with Kap1 in HCC patients are important because they provide not only a predictor for HCC prognosis but also a therapeutic target for future studies.

ABSTRACT
In the present study we measured the lipid peroxide content in plasma and lung homogenate by Yagi's method, and analyzed the composition of surfactant phospholipid and surface activity of pulmonary surfactant by thin layer chrom-otography and by Wilhelmy's film balance.The results showed that the lipid peroxide level was increased in plasma and lung homogenate; licithine,tysopho-spholipidcholine and phosphatidylethanolamine were decreased in bronchial-alveolar lavege fluid; and pulmonary surfactant surface activity was lowered.The findings suggest that decreased surface activity may result from the decrease of disaturated phospholipidcholine, which may be due to its impaired synthesis.
