The construction of a medication safety culture is important for medication safety management and rational drug use.The construction of medication safety culture standards is formulated based on relevant national policies and regulations,accreditation standards for hospitals,expert opinions,the current situation,and the development trend of the healthcare industry.With scientificity,general applicability,instructive guidance,and practicality,they standardized basic requirements,management processes,and improvement of the construction of medication safety culture.To facilitate understanding and the implementation of the standards,we describe the process of standards formulation and explain the key points of the standards.

Objective:To study cerebral oxygen metabolism and cerebral blood flow in etomidate and sevoflurane anesthesia effects of perfusion and postoperative delusions.Methods:A prospective study was used. The 96 elderly patients who underwent elective spinal surgery in Guang′anmen Hospital, China Academy of Chinese Medical Sciences from March 2020 to May 2021 were selected as the study subjects. All patients were divided into sevoflurane group and etomidide group by random numbers table, each with 48 cases. The sevoflurane group was treated with sevoflurane inhalation for analgesia, with etomidate intravenous-controlled analgesia in the etomidate group. The recovery time of spontaneous respiratory, wake time, awake extubation time, numerical rating score (NRS; 1, 3, 6, 12, 24 and 48 h), incidence of postoperative delusion, internal jugular vein oxygen saturation (SjvO 2) were recorded. Arteriovenous oxygen content (AVDO 2) and cerebral oxygen intake rate (CERO 2) were calculated. The peak cerebral artery constriction rate (Vs-MCA), diastolic velocity (Vd-MCA) and mean flow rate (Vm-MCA) pre-induction of anesthesia (T 0), loss of consciousness (T 1), after fentanyl injection (T 3), endotracheal intubation (T 4), 30 min (T 5), 60 min (T 6) and postoperative (T 7) were recorded. Results:There were no significant differences in the recovery time of spontaneous breathing, wake time and awake extubation time between the two groups ( P>0.05). The resting NRS in sevoflurane group at 1, 3, 6, 12, 24 and 48 h after operation were (1.27 ± 0.12), (2.13 ± 0.22), (3.26 ± 0.23), (3.29 ± 0.22), (2.52 ± 0.11) and (2.02 ± 0.11) points, respectively. Etomidate group was (1.27 ± 0.13), (2.02 ± 0.21), (2.13 ± 0.13), (2.11 ± 0.26), (2.08 ± 0.17) and (1.02 ± 0.17) points, respectively. The results of repeated measurement ANOVA showed that there was significant difference in NRS between the two groups ( P<0.05). There were significant differences in postoperative resting NRS between the two groups at different time points ( P<0.05). The incidence of postoperative delusion in etomidate group was lower than that in sevoflurane group: 4.17% (2/48) vs. 16.67% (8/48), and the difference was statistically significant ( P<0.05). Postoperative SjvO 2 in sevoflurane group and etomidate group was higher than that before surgery: (69.96 ± 4.17)% vs. (58.26 ± 4.16)%, (61.22 ± 4.19)% vs. (58.25 ± 4.17)%. In addition, both AVDO 2 and CERO 2 were lower than those before operation: (60.23 ± 5.22)% vs. (64.22 ± 4.17)%, (50.23 ± 6.19)% vs. (64.23 ± 4.19)%, (37.22 ± 6.23)% vs. (40.23 ± 5.16)%, (31.26 ± 5.17)% vs. (40.27 ± 4.18)% ( P<0.05), postoperative SjvO 2 in etomidate group was higher than that in sevoflurane group, and AVDO 2 and CERO 2 were lower than that in sevoflurane group. The difference was statistically significant ( P<0.05). The results of repeated measurement ANOVA showed that there were statistically significant differences in cerebral blood perfusion indexes of Vs-MCA, Vd-MCA and Vm-MCA between the two groups ( P<0.05). There were statistically significant differences in Vs-MCA, Vd-MCA and Vm-MCA between two groups at different time points ( P<0.05). There were significant differences in Vs-MCA, Vd-MCA and Vm-MCA between the two groups at different time points ( P<0.05). Conclusions:Compared with sevoflurane, etomidate can reduce the postoperative delusion rate, improve cerebral oxygen metabolism and reduce cerebral blood flow perfusion.

Objective To compare the safety and efficacy of direct and remedial rotational atherectomy in the treatment of heavily calcified coronary artery lesions.Methods We retrospectively reviewed 58 patients admitted in the Shanghai Chest Hospital and Liaocheng People Hospital from May 2012 to July 2015 who had received stent implantation and rotational atherectomy.The 58 patients were divided into two groups which were the direct atherectomy group (n =27) and the remedial atherectomy group (n =31).General clinical date,lesion and procedural characteristics,intraoperative complications,in-hospital and follow-up MACCE were compared between the two groups.Results There were no differences between the two groups in general clinical date intraoperative complications,amount of contrast agent used,proceduraltime,rates of in-hospital and follow-up MACCE.Nevertheless,compared with the direct artherectomy group,the remedial group had more number of balloon dilations during procedure [3 (1,5) vs.2 (1,2),P ＜ 0.001] and higher peak cardiac troponin levels [1.1 (0.3,3.0) μg/L vs.0.5 (0.1,2.3) μg/L,P =0.032].Conclusions Remedial rotational atherectomy with drug-eluting stent had the same safety and efficacy as direct atheretomy with drug-eluting stent in treating patients with heavily calcified coronary lesions.It is reasonable and safe to transform routine PCI to remedial rotational atherectomy when the 2.0 mm semi compliant balloon or/and 2.5 mm non-compliant balloon cannot pass through or dilate the lesions.

AIM: To study the action of Shugan Pills (SHGP) (Fructus Toosendan, Rhizoma corydalis, Radix Paloniae Albe, Radix Aucklandiae, Cortex Magnoliae Officinalis, Fructus Aurantii, etc.) on treatment of epigastralgia. METHODS: The analgesic effect was tested by the hot plate test and writhing method. The anti gastric ulcer action of SHGP was observed on the gastric ulcer induced by water immersion stress, reserpine and absolute ethyl alcohol. The effect on gastric secretion in rats was studied with pylorus ligation. The effect on gastrointestinal motility was observed by determination of gastric emptying and small intestinal propulsion ability in mouse. RESULTS: SHGP enhanced hot pain threhshold and decreased the number of twisting body in mouse. SHGP markedly inhibited gastric ulcer induced by water immersion stress, reserpine and absolute ethyl alcohol. SHGP significantly inhibited the secretion of gastric acid and pepsin and promoted the secretion of gastric mucus. SHGP markedly delayed gastric emptying in normal mouse and when gastric emptying and small intestinal propulsion was stimulated by neostigmine. SHGP faintly strengthed the effect of atropine on inhibition of gastrointestinal motility. CONCLUSION: Shugan Pills could have analgesic effect, anti gastric ulcer action, it inhibited the secrection of gastric juice and the activity of gastric smooth muscle. These effects might be the pharmacological mechanisms of SHGP on treatment of epigastralgia.

AIM:To investigate the effects of Zhouluotong (Radix Astragali, Ramulus Cinnamomi, Radix Angelicae Sinensis, Radix Rchmannia, Herba Asari, etc.) on nerve function and polyol pathway in streptozotocin diabetic rats. METHODS: Streptozotocin diabetic rats were administrated with Zhouluotong for 8 weeks. Effects of drugs on sciatic never morphological alterations, sciatic never conduction velocity, aldose reductase activity, Na +,K + ATPase activity and sciatic nerve polyol contents were determined. RESULTS: Compared with diabetic group, sciatic never morphological alterations was improved, sciatic never conduction velocity was increased, aldose reductase activity was depressed and Na +,K + ATPase activity was increased in each administrated group. Sorbitol and gloucose contents were decreased in Zhouluotong groups. CONCLUSION: Zhouluotong could improve metabolism and function of peripheral nerve issue in streptozotocin diabetic rats. As a result of that, it could prevent diabetic peripheral neuropathy in streptozotocin diabetic rats.

Objective To study the protective action of Shuganwan on liver injury and its cholagogue action. Methods Acute liver injury was induced by carbon tetrachloride in rats. The biochemical indexes and pathological changes were used for evaluation. The cholagogue action was studied by biliary drainage method. Results Compared with those of the CCl 4 control group, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and bilirubin levels of Shuganwan group declined significantly, and albumin/ globulin (A/G) inversion was obviously improved. The pathological changes revealed that liver injury was relieved. There was no change in bile secretion after administration of Shuganwan. Conclusion Shuganwan has protective action on acute liver injury by carbon tetrachloride, but no promotive action on bile secretion.
