OBJECTIVE:To improve community pharmaceutical care so as to promote the rational drug use of community resi-dent and improve the quality of life. METHODS:By analyzing the situation of community pharmaceutical care,the pharmaceutical care of community pharmacists was improved by changing pharmaceutical care mode,actively developing the propaganda of ratio-nal drug use,strengthening retraining of clinical pharmacists. RESULTS:With the help of Hongkou district quality control group, many hospitals of the district signed thepharmaceutical linkage assistance agreement. Through the efforts of Hongkou district quality control group and many hospitals,community pharmaceutical care was improved and the propaganda of rational drug use has achieved certain results. CONCLUSIONS:Through exploration and practice,the pharmaceutical care levels of community phar-macists have been improved and the rational drug use of community residents has been promoted.
3.Research progresson the mechanism and safetiness of salvianolic acid injectionin treating cardiovascular disease
International Journal of Traditional Chinese Medicine 2021;43(8):830-833
Salvianolic acid injection play an important role in cardiovascular diseases by promoting angiogenesis, improving hemorheology, anti-platelet aggregation, anti-inflammatory, anti-oxidative stress, improving endothelial cell function, and inhibiting atherosclerosis. However, mechanismstudies focusing on molecular level are quite few. Although there are many adverse reactions and many factors causing adverse reactions, the incidence rate of adverse reactions is low with safety.

Objective To develop a novel skin microdialysis technology in vivo,and to determine the pharmacokinetic of ba-icalin after transdermal administration in rats. Methods An HPLC-MS/MS method used for the determination of baicalin in skin mi-crodialysis samples was established ,SD rats were pretreated with skin microdialysis operation under anesthesia , and then the baicalin gel was applied to the skin surface of probe in vivo.The baicalin concentration of skin microdialysates was determined , the time curve of baicalin concentration was drawn and the topical pharmacokinetics parameters of percutaneous absorption was calculated. Results Baicalin was optimized at the transitions m/z 447.3→271.2.The linearity correlation was good and the assay exhibited good precision and accuracy.The subcutaneous probe recovery of baicalin in vivo was(24.40 ±0.91)%and was stable over the 240 min study peri-od.Baicalin could be detected in the microdialysis samples after transdermal administration , and its concentration continued to rise in 8 h.AUC0-t in skin tissue was(50.04 ±34.17) mg· min· L-1. Conclusion The method of skin microdialysis in vivo could be used in the local pharmacokinetic research of baicalin.

OBJECTIVE To mine adverse drug event (ADE) signals of lacosamide, and to provide references for clinically safe drug use. METHODS ADE data for lacosamide reported to the United States FDA adverse event reporting system from January 1, 2009, to December 31, 2022, were collected. Data mining was conducted using the reporting odds ratio method and Bayesian confidence propagation neural network method. Classification statistics were performed using the system organ class (SOC) and preferred terms (PT) from ADE terminology set of Medical Dictionary for Regulatory Activities (Version 25.0). RESULTS A total of 21 360 lacosamide ADE reports were received, identifying 203 ADE signals across 24 SOCs, with 19 signals not included in the drug’s instruction. The top five PTs ranked by occurrence frequency were medication overdose, technical errors during device use, product use issues, intentional product misuse, and therapy discontinuation. The top five PTs ranked by signal strength were changes in seizure presentation type, congenital hypoplasia of depressor anguli oris muscle, multidrug resistance, brain surgery, and vagus nerve stimulator implantation. ADEs not recorded in the drug instruction included congenital hypoplasia of depressor anguli oris muscle, multidrug resistance, mitochondrial DNA mutation, dissociative identity disorder, and congenital auricular anomaly. CONCLUSIONS For lacosamide-induced ADEs that occur frequently and are already listed in the drug’s instructions, such as bradycardia and atrioventricular block, the clinical application should be careful and attentive, adjusting the dosage timely according to the patient’s condition to avoid severe ADEs. Newly discovered suspect ADEs, such as congenital hypoplasia of depressor anguli oris muscle, mitochondrial DNA mutation, overmature infant, dissociative identity disorder, pigmenturia, behavioral disorders, and dissociative disorders, should be vigilantly recognized to ensure the safety of drug use.

Objective To evaluate the effects of puerarin on bone density in rats and mice through a meta-analysis. Methods The databases, including CNKI, SinoMed, Wanfang data, VIP, PubMed, EMBase, Web of Science, the Cochrane Library, and Scopus from their inception to November 6, 2023, were searched for literature on the effects of puerarin treatment on bone density in rats and mice. Inclusion criteria for the literature were randomized controlled trials with a placebo or blank control group; the subject animals were rats or mice; the intervention was puerarin; and the results included bone density measurements. Exclusion criteria included combination therapy with puerarin; lack of original research data; unpublished studies; and using mandible as the measurement site for bone density. Risks of bias were assessed using SYRCLE's RoB tool. Data analysis was conducted with Stata 16.0 and Rev Man 5.3 software. Results After applying the inclusion and exclusion criteria, a total of 429 records were identified and 42 articles covering 41 studies were ultimately included. 925 animals were involved and the data analysis results indicated that puerarin improved bone density in rats and mice compared to the control group: femur [37 studies, n=824, standardized mean difference (SMD)=2.12, 95% confidence interval (CI)=1.69-2.54, P < 0.000 1], lumbar spine (13 studies, n=271, SMD=2.25, 95% CI=1.49-3.01, P < 0.000 1), tibia (4 studies, n=95, SMD=0.94, 95% CI=0.05-1.83, P=0.04), and the whole body (4 studies, n=94, SMD=1.89, 95% CI=0.50-3.29, P=0.008), with all inter-group differences in bone density being statistically significant. Conclusion Puerarin can improve bone density in rats and mice. This study provides a valuable reference for clinical studies on the prevention and treatment of osteoporosis with puerarin.
