1.Review on identification and prevention-control strategies for public health risks in pharmacy intravenous admix-ture services
China Pharmacy 2026;37(2):268-272
Pharmacy intravenous admixture serves as a core link in the clinical medication supply chain. Its operational quality is directly related to drug safety and patient medication safety. This paper examines the challenges and measures for public health risk prevention and control in practical operational aspects of intravenous drug preparation, including prescription verification, drug compounding, drug management, and finished product distribution and traceability. Grounded in the “prevention-control-emergency response” full-chain management framework, it proposes systematic prevention and control strategies, including establishing a “public health-oriented” pharmacy intravenous admixture service management system, strengthening risk intervention measures throughout the entire process, improving risk monitoring and emergency response mechanisms, promoting technological empowerment, and refining pharmacist training and personnel qualification control mechanisms. These efforts aim to establish a comprehensive public health safety system that shifts from a “passive response” to an “active prevention and control” approach, thereby ensuring patient medication safety.

N,N-Dimethylglycine (DMG) is a glycine derivative, and its sodium salt (DMG-Na) has been demonstrated to possess various biological activities, including immunomodulation, free radical scavenging, and antioxidation, collectively contributing to the stability of tissue and cellular functions. However, its direct effects and underlying mechanisms in wound healing remain unclear. In this study, a full-thickness excisional wound model was established on the dorsal skin of mice, and wounds were treated locally with DMG-Na. Wound healing progression was assessed by calculating wound closure rates. Histopathological analysis was conducted using hematoxylin-eosin (HE) staining, and keratinocyte proliferation, migration, and differentiation were evaluated using CCK-8 assays, scratch wound assays, and quantitative reverse transcription PCR (qRT-PCR). Inflammation-related cytokine expression in keratinocytes was analyzed via ELISA and qRT-PCR. Results revealed that DMG-Na treatment significantly accelerated wound healing in mice and improved overall wound closure quality. The wound healing rates on days 3, 6, and 9 were 49.18%, 68.87%, and 90.55%, respectively, with statistically significant differences compared to the control group ( P<0.05). DMG-Na treatment downregulated the mRNA levels of keratinocyte differentiation markers while enhancing cell proliferation and migration ( P<0.05). Furthermore, DMG-Na decreased the secretion of LPS-induced keratinocyte inflammatory cytokines, including IL-1β, IL-6, IL-8, TNF-α, and CXCL10 ( P<0.05). These findings indicate that DMG-Na regulates inflammatory responses and promotes keratinocyte proliferation and migration, thereby facilitating the healing of skin wounds.

Yi He Rehabilitation,which is based on traditional Chinese rehabilitation treatments and rehabilitation principles from modern medicine,is effective in staging treatment of post-stroke hemiplegia.This paper systematically discusses the origin and annotation of Yi and He from the perspectives of traditional Chinese medicine and modern medicine.The medicinal connection between Yi and the body and its function is related to unobstructed attunement.Based on the connotation of Yi and He,we believe that the pathogenesis of post-stroke hemiplegia is the comprehensive result of abnormal effects of Yi on the organism at the microscopic level and abnormal effects of He on function at the macroscopic level,featured as tense muscle movement and a pathological process of abnormal motion,including the disturbance of yang qi with body dysfunction,the disorder of spirit with sinews and vessels with diversion,and the variation of brain collateral with physical and mental inconsistency.By inducing relaxation and calmness,Yi He rehabilitation takes effect in staging treatment of post-stroke hemiplegia with characteristic mechanisms.First,by calming ascending yang and relaxing the disordered body in periods of relaxation,it can achieve the maintenance function of the kinematic chain peripherally with passive rehabilitation.Second,by calming the disordered spirit and relaxing the inhibited meridian sinews in spasmodic periods,it can reconstruct the neural plasticity of motor function centrally with assistive rehabilitation.Third,by calming damaged brain collateral and relaxing the impassable zang organs in the recovery period,it can close the central-peripheral-central loop of rehabilitation with active rehabilitation.

Objective:
To clarify the specific mechanisms of action of raw Phellodendron chinense Schneid. (RPC) and saltwater-processed PC (SPC) in the treatment of rats with a kidney-yin deficiency pattern (KYDP).
Methods:
Healthy rats were administered hydrocortisone to establish a KYDP model. The rats were divided into seven groups: blank control, model, positive control (Liuwei Dihuang pills), high-dose RPC, low-dose RPC, high-dose SPC, and low-dose SPC. Enzyme-linked immunosorbent assay was used to measure the levels of cAMP, cGMP, TRH, TSH, T3, T4, IFN-γ, TNF-α, and testosterone in the serum and the levels of Na+-K+-ATPase and Ca2+-Mg2+-ATPase in the liver. TRH mRNA expression in the rat hypothalamus was measured using RT-PCR. THRα1+2 protein expression in the hypothalamus of rats was measured using Western blot. Immunohistochemistry was performed to determine the expression levels of FAS, FasL, and TSHR. Flow cytometry was used to determine CD4+ and CD8+ T lymphocyte levels. Illumina MiSeq sequencing technology was used to evaluate the diversity of intestinal flora in KYDP rats.
Results:
The cAMP/cGMP ratio was significantly higher in the model group than in the blank control group (P = .048). Compared with the model group, after administration, the levels of the above-mentioned serum and liver indexes decreased, except that of testosterone. The CD4+/CD8+ ratio also decreased. Compared with the RPC group, the levels of T3, IFN-γ, FAS, FasL, and TSHR in the SPC group decreased whereas that of testosterone increased. Additionally, immune function and intestinal flora diversity improved in the SPC group. SPC proved to be more effective in improving liver energy metabolism in KYDP rats than RPC.
Conclusion
SPC had a better therapeutic effect on KYDP than RPC. The underlying mechanism of action may be related to improvements in liver energy metabolism, immune function, and intestinal flora diversity.

Ghrelin, a hormone mainly produced and released by the stomach, has numerous functions, including releasing growth hormones, regulating appetite, and processing sugar and lipids. Researchers have made great efforts to study the relationship between ghrelin and metabolic diseases. It is believed that human butyrylcholinesterase (hBChE) could hydrolyze ghrelin to the inactive form (desacyl-ghrelin). However, the low catalytic activity of wild hBChE against ghrelin hinders the clinical application. Recently, a soluble catalytically active hBChE mutant was successfully expressed in Escherichia coli for the first time. We then adopted HotSpot Wizard 3.0 to analyze the mutant structure and rationally selected 10 mutants. Furthermore, we determined the catalytic activities of the mutants against several substrates and the thermostability of these mutants. The results showed that the mutants E197D and A199S improved catalytic activity against ghrelin by 4.6 times and 3.5 times, respectively. The findings provide clues for treating endocrine diseases with the agents for regulating ghrelin.

In addition, echinococcosis was screened in sheep and cattle in designated slaughterhouses in Tianzhu Tibetan Autonomous County. The trends in the prevalence of echinococcosis in humans and livestock and the positive rate of Echinococcus coproantigens in dogs were examined with the Cochran-Armitage trend test. In addition, individuals screened for echinococcosis were randomly sampled from 2007 to 2022 for survey on the awareness of echinococcosis control knowledge. Results A total of 290 356 person-times were screened for echinococcosis among residents at ages of 12 years and older in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 1 094 residents detected with cystic echinococcosis, and the detection of echinococcosis appeared a tendency towards a gradual decline over years (χ2 = 358.602, P < 0.001). A total of 32 931 person-times were screened for echinococcosis among children at ages of 12 years and older in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 296 children detected with echinococcosis, and the detection of echinococcosis appeared a tendency towards a gradual decline over years (χ2 = 267.673, P < 0.001). A total of 33 230 domestic dog stool samples were tested for Echinococcus coproantigens in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 1 777 Echinococcus coproantigens-positive samples tested, and the positive rate of Echinococcus coproantigens appeared a tendency towards a decline in domestic dogs over years (χ2 = 2 210.428, P < 0.001), while the positive rate of Echinococcus coproantigens showed a tendency towards a rise in domestic animals from 2016 to 2022 (χ2 = 37.745, P < 0.001). The positive rate of Echinococcus coproantigens remained relatively stable in stray dogs in Tianzhu Tibetan Autonomous County, Gansu Province from 2019 to 2022 (χ2 = 0.315, P = 0.575). A total of 10 973 sheep were screened for echinococcosis in Tianzhu Tibetan Autonomous County from 2007 to 2022, with 334 sheep detected with echinococcosis, and the detection of echinococcosis appeared a tendency towards a decline in sheep over years (χ2 = 53.579, P < 0.001); however, there was no significant change in the detection of echinococcosis during the period from 2015 through 2022 (χ2 = 1.520, P = 0.218). A total of 2 400 cattle were screened for echinococcosis in Tianzhu Tibetan Autonomous County from 2017 to 2022, with 231 cattle detected with echinococcosis, and the detection of echinococcosis showed a tendency towards a decline over years (χ2 = 5.579, P < 0.05). The awareness of echinococcosis control knowledge increased from 44.37% in 2007 to 94.00% in 2022 among residents at ages of 12 years and older and from 52.50% in 2007 to 92.50% in 2022 among children at ages of 12 years and older in Tianzhu Tibetan Autonomous County, respectively. Conclusions There has been a reduction in the detection of echinococcosis in humans and domestic animals and the positive rate of Echinococcus coproantigens in dogs and a rise in the awareness of the echinococcosis control knowledge following the implementation of the central government-funded echinococcosis control programme in Tianzhu Tibetan Autonomous County, Gansu Province; however, integrated echinococcosis control measures are still required for further control of the prevalence of echinococcosis.

Objective:To investigate the amyloid precursor protein (APP) expression in brain glioma tissues and cerebrospinal fluid of glioma patients and their significances.Methods:(1) Fifty-six brain glioma specimens surgically resected and pathologically confirmed in our hospital from January 2015 to December 2020 were collected, including 9 with WHO grading I, 14 with WHO grading II, 18 with WHO grading III, and 15 with WHO grading IV. In addition, the necrotic brain tissues of 4 patients with hypertensive intracerebral hemorrhage during hematoma removal at the same time period were collected as controls. Western blotting and real-time quantitative PCR (RT-qPCR) were used to detect the APP protein and mRNA expressions in glioma tissues and control brain tissues, respectively. (2) The cerebrospinal fluid of above 56 patients with glioma, 4 patients with viral meningitis, 4 patients with bacterial meningitis, 4 patients with autoimmune encephalitis, 5 patients with epilepsy, 3 patients with migraine and 3 normal subjects were collected at the same time period, and the APP content in the cerebrospinal fluid of all subjects were detected by ELISA.Results:(1) Western blotting and RT-qPCR showed that the APP protein and mRNA expressions in glioma tissues of WHO grading I, II, III and IV were significantly higher than those in control brain tissues, and the APP protein and mRNA expressions in glioma tissues of WHO grading I, II, III and IV increased successively, with statistical differences ( P<0.05). There were no significant differences in APP protein and mRNA expressions between first-onset glioma and recurrent glioma in glioma tissues of WHO grading I and II ( P>0.05); while in glioma tissues of WHO grading III and IV, APP mRNA expression in recurrent glioma was statistically higher than that in first-onset glioma ( P<0.05). (2) ELISA results showed that APP content in patients with viral meningitis, bacterial meningitis, autoimmune encephalitis, epilepsy or migraine was not significantly different as compared with that in normal controls ( P>0.05). The APP content in cerebrospinal fluid of patients with WHO grading I, II, III and IV gliomas was significantly higher than that in normal controls, and the APP content in cerebrospinal fluid of patients with WHO grading I, II, III and IV gliomas increased successively, with statistical differences ( P<0.05). Conclusion:APP is highly expressed in glioma tissues and cerebrospinal fluid of patients with glioma, and its expression is significantly correlated with the pathological grades of glioma; the detection of APP expression in cerebrospinal fluid can be used as a new screening method for glioma patients.
