ABSTRACT
OBJECTIVE To establish a database of rational drug use for children in our hospital， and to provide reference for ensuring the safety of drug use in children. METHODS The construction and filling of the knowledge base of rational drug use for children were performed by establishing the basic structure of the knowledge base， formulating reference standards for the quality level of pediatric medication evidence， and refining evidence-based evidence of pediatric medication. The rule base of rational drug use for children was designed and built from four aspects： preliminary determination rules for patient information， basic drug information rules， prescription suitability review rules， result labeling and post-processing rules. The database was embedded into prescription review system of our hospital and was applied online to test its effectiveness. RESULTS A set of database containing 672 commonly used pediatric medicines and more than 15 000 rules for rational drug use for children was initially constructed. The average interception rate of unreasonable medical orders for hospitalized children after database application（from December 2021 to May 2022）was 2.03%， and was higher than 0.80% before database application（from June 2021 to November 2021）（χ 2＝5 784.389， P＜0.001）； after post-sampling and prescription review， the average qualified rate of medication orders in discharged medical records for children after the application of the database was 99.10%， and was higher than 94.58% before the application of the database （χ 2＝301.237， P＜0.001）. CONCLUSIONS Self-constructed evidence-based rational drug use database for children is close to the actual clinical needs of pediatrics in medical institutions， which can effectively reduce clinical irrational drug use behaviors in pediatrics， improve the pass rate of prescriptions， and ensure the safety of children’s drug use.
ABSTRACT
Objective To compare the lymph node dissection of left chest single incision and neck-right chest-abdomen incision in esophageal cancer surgery,and to explore the reasonable range of lymph node dissection in esophageal cancer surgery.Methods We retrospectively analyzed the clinical data of 72 patients with esophageal cancer radical surgery.According to the surgical approach,the patients were divided into left chest single-incision group (32 cases) and three-incision group (40 cases).The surgery time,number of lymph node resected,drainage tube time,length of hospital stay,lymph node dissection status and incidence of postoperative complications were analyzed.Results In left chest single-incision group and three-incision group,the operative time [(225.44 ± 11.98) min vs (265.42 + 13.15) min],lymph node dissection number[(8.031 ± 1.153) vs (11.821 ± 1.138)],length of stay [(13.212 ± 1.294) d vs(15.691 ± 1.404) d] and other aspects had statistically significant differences (t =24.201,25.302,14.010,all P ＜ 0.05).There were no significant differences between two groups in the chest tube indwelling time and the incidence of postoperative complications (P ＞ 0.05).Conclusion Both surgical radical resection of esophageal cancer have their own characteristics in terms of surgical difficulty,risks,efficacy and complications.In clinical,these must be carefully evaluated in patients with lesions and body affordability flexibility to choose the surgical approach in order to achieve the best therapeutic effect.
ABSTRACT
Objective To explore a positive Ji treatment clinical application and effect before the mouth cavity repairs,analyzing and providing a reference method for positive Ji treatment. Methods To analyze 80 adult's sufferers, all adopt to fixedly correct and cure a machine to correct and cure,match square silk bow or keep silk bow to correct and cure technique and assistance device, the treatment is 7～33 months. Carry on an analysis discussion to the treatment method and effect, clinical characteristics of adult positive Ji at the same time. Results In 80 sufferers,show effect 65 people,have 81.25%;Effective 14 people have 17.5%;Invalid one person has 1.25%.In addition to invalid,the rest sufferer all has better pronunciation and beautiful effect after the positive Ji cures and all have never taken place bad reaction. Conclusion The mouth cavity repairs ex-positive Ji the treatment not only create a condition for repair treatment and promote repair the treatment attain better clinical effect, can also make mouth cavity organize to keep healthy betterly and obviously improve a sufferer the tooth image and noodles permits of beauty.
ABSTRACT
Aim To study the anti-inflammator y and antiallergic effects of polysaccharide nucleic acid fraction of bacillus cal mette guerin (BCG-PSN). Methods Effect of BCG-PSN on itch thr eshold of guinea pigs caused by phosphoric acid histamine, ear oedema of mice ca used by xylene, carrageenan-induced hind paw oedema in rats, delayed hypersensi tivity reaction induced by 2,4-dinitroflurobenzene in mice, homologous passive cutaneous anaphylaxis in rats and heterologous passive cutaneous anaphylaxis in mice were investigated. BCG-PSN was administered intramuscularly every other d ay for three weeks. Results BCG-PSN(0.1,0.2,0.4 mg?kg -1) had no effect on itch threshold of guinea pigs caused by phosphoric aci d histamine. In mice, BCG-PSN(0.15,0.30,0.60 mg?kg -1) significant ly inhibited ear oedema caused by xylene and heterologous passive cutaneous anap hylaxis in a dose-dependent manner. BCG-PSN at the dose of 0.60 mg?kg -1 also significantly inhibited delayed hypersensitivity reaction induced by 2,4 -dinitroflurobenzene in mice. In rats, BCG-PSN(0.1,0.2,0.4 mg?kg -1 )significantly inhibited carrageenan-induced hind paw oedema and homologous passive cutaneous anaphylaxis. Conclusion BCG-PSN inhibites ac ute inflammation, immediate type allergy and delayed type allergy.
