ABSTRACT
Objectives@#Understanding the lingual nerve’s precise location is crucial to prevent iatrogenic injury. This systematic review seeks to determine the lingual nerve’s most probable topographical location in the posterior mandible. @*Materials and Methods@#Two electronic databases were searched, identifying studies reporting the lingual nerve’s position in the posterior mandible.Anatomical data in the vertical and horizontal dimensions at the retromolar and molar regions were collected for meta-analyses. @*Results@#Of the 2,700 unique records identified, 18 studies were included in this review. In the vertical plane, 8.8% (95% confidence interval [CI], 1.0%-21.7%) and 6.3% (95% CI, 1.9%-12.5%) of the lingual nerves coursed above the alveolar crest at the retromolar and third molar regions. The mean vertical distance between the nerve and the alveolar crest ranged from 12.10 to 4.32 mm at the first to third molar regions. In the horizontal plane, 19.9% (95% CI, 0.0%-62.7%) and 35.2% (95% CI, 13.0%-61.1%) of the lingual nerves were in contact with the lingual plate at the retromolar and third molar regions. @*Conclusion@#This systematic review mapped out the anatomical location of the lingual nerve in the posterior mandible, highlighting regions that warrant additional caution during surgeries to avoid iatrogenic lingual nerve injuries.

ABSTRACT
Brain-computer interface (BCI) is a revolutionizing human-computer Interaction, which is developing towards the direction of intelligent brain-computer interaction and brain-computer intelligent integration. However, the practical application of BCI is facing great challenges. The maturity of BCI technology has not yet reached the needs of users. The traditional design method of BCI needs to be improved. It is necessary to pay attention to BCI human factors engineering, which plays an important role in narrowing the gap between research and practical application, but it has not attracted enough attention and has not been specifically discussed in depth. Aiming at BCI human factors engineering, this article expounds the design requirements (from users), design ideas, objectives and methods, as well as evaluation indexes of BCI with the human-centred-design. BCI human factors engineering is expected to make BCI system design under different use conditions more in line with human characteristics, abilities and needs, improve the user satisfaction of BCI system, enhance the user experience of BCI system, improve the intelligence of BCI, and make BCI move towards practical application.

Standards for Prescription Review in Medical Institutions puts forward higher requirements for the pharmacists' ability to review prescriptions, and the dispensing pharmacist should review the legality, standardization, and suitability of the prescription. Centralized training helps to improve the pharmaceutical care capacity and promote the rational use of drugs in hospitals. The centralized training course system designed by our hospital includes four modules: laws and regulations, prescription suitability review for drugs commonly used in each department, prescription suitability review for drugs used in the special population, and prescription suitability review for specialty drugs. The training system has the characteristics of homogeneity and standardization. A combination of theoretical courses and practical exercises, as well as the introduction of problem-based learning and case-based learning, holds promise for application in the training of dispensing pharmacists.
ABSTRACT
OBJECTIVE:To explore the role of clinical pharmacists in the treatment of critical patients at perinatal stage. METHODS:During the treatment process of 4 critical patients at perinatal stage,according to the patients'special pathophysiolog-ic status (such as urea cycle disorder,dyslipidemia,severe infection,can not recover circulating blood volume rapidly,etc.), weighing the order of priority,based on relevant guidelines and literatures,clinical pharmacists provided individual medication ad-vices in respects of drug selection,medication timing,treatment course,drug combination and dosage adjustment,such as using cefuroxime,reduced glutathione,ursodesoxycholic acid,etc.,stopping drugs timely or adjusting antibiotics therapy plan. They al-so provided pharmaceutical care as lab index determination and ADR monitoring. RESULTS:Physicians adopted clinical pharma-cists'advices,and then 4 critical patients were all recovered. CONCLUSIONS:During the treatment course of critical patients at perinatal stage,clinical pharmacists should select safe and effective drugs as much as possible and adjust therapy plan in time ac-cording to clinical symptoms. When the security runs counter to effectiveness,clinical pharmacists should fully weigh the advantag-es and disadvantages and guarantee the maximum safety of pregnant or delivery women and fetuses.

ABSTRACT
Objective: To determine the pharmacokinetics of ephedrine hydrochloride in rats after intragastric administration of Shegan mixtures. Methods:Shegan mixtures (1. 0 ml/100 g) were administered to each rat by gavage. Blood samples were collected after the administration. Plasma concentration of ephedrine hydrochloride was determined by LC-MS/MS. The pharmacokinetic parame-ters of ephedrine hydrochloride were obtained using the pharmacokinetic software. Urine and fecal samples were collected in 24 hours after the administration using metabolic cage to determine the recovery of ephedrine hydrochloride. Results: The pharmacokinetic pa-rameters of ephedrine hydrochloride were as follows:Tmax of (1. 30 ± 0. 23)h,T1/2 of (21. 17 ± 1. 35)h, Cmax of (278. 86 ± 46. 41)ng ·ml-1,AUC0~∞ of (1221.98 ±412.64)ng·ml-1 and Vc/F of (1.70 ±0.15)L. Totally 85.66% ephedrine hydrochloride could be recovered from urine in 24 hours after the administration;however, it was not detected in the fecal samples. Conclusion: Most of e-phedrine hydrochloride is excreted through kidney in 24h,therefore, Shegan mixtures can't cause the accumulation of ephedrine hydro-chloride in rats.
