OBJECTIVE To identify tortoiseshell glue and antler glue in Qichong zuogui granules， and determine the contents of 12 chemical components. METHODS Identification and content determination were performed by using liquid chromatography- tandem mass spectrometry （LC-MS/MS） method. The identification was performed on Hypersil GOLD column with a mobile phase consisted of acetonitrile-0.1% formic acid solution （gradient elution）； the electrospray ion source was used to scan in the positive ion multi-reaction detection mode. The mass charge ratio （m/z） 631.3→546.4， 631.3→921.4 was the detection ion pair for tortoiseshell glue， and the m/z 765.4→554.0， 765.4→733.0 was the detection ion pair for antler glue. The determination method for 12 chemical components was as follows： Accucore C18 column， methanol-0.1% formic acid as mobile phase （gradient elution）； scanning range of positive and negative ions was m/z 100→1 000 with the electric spray ion source and single ion detection scanning mode. RESULTS Average retention times of the molecular ion peaks for characteristic peptide segments of tortoiseshell glue and antler glue were 6.28 and 6.77 min， respectively； the linear relationship of 12 chemical components was good within their respective concentration ranges， such as astragaloside Ⅳ， calycosin-7-O-β-D-glucoside， calycosin， chlorogenic acid， ferulic acid， betaine， amygdalin， rutin， hydroxysafflor yellow A， hyperoside， loganin， cyasterone （r＞0.999）； RSDs for precision， stability （24 h） and reproducibility tests were all less than 5%. The average sample recovery rates ranged from 98.04% to 101.08%. The average contents of 12 components were 1.83， 25.73， 13.76，56.71， 23.80， 49.82， 807.49， 15.01， 317.02， 60.21， 202.71 and 17.70 μg/g， respectively.

This provides a reference for the quality control of this granule.

Objective: To evaluate the efficacy of ultraviolet-C (UVC) irradiation in inactivating porcine parvovirus (PPV), encephalomyocarditis virus (EMCV), pseudorabies virus (PRV) and vesicular stomatitis virus (VSV) within von Willebrand factor (vWF) preparations. Methods: An ultraviolet inactivator (254 nm primary wavelength) was employed to optimize UV exposure dosages for the samples, and the initial test groups were set at five irradiation gradients: 100, 200, 400, 1 000, and 1 500 J/m gradients. Based on the results of the preliminary experiments, subsequent formal experiments implemented refined dosage parameters at 100, 125, 150, 175, and 200 J/m . Virucidal efficacy against various pathogenic strains was evaluated via cytopathic effect (CPE) observation methodology, while simultaneously quantifying von Willebrand factor antigen levels (vWF∶Ag) and collagen-binding activity (vWF∶CBA) using enzyme-linked immunosorbent assays (ELISA) and automated coagulation analysis systems before and after UVC treatment. Results: The results showed that > 100 J/m UVC irradiation achieved a≥4.0 log reduction factor in vWF. For vWF antigen, retention rates were observed to be 93.67%, 91.72%, 93.54%, 79.05%, and 85.50% at UVC doses of 100, 125, 150, 175, and 200 J/m , respectively. Similarly, the retention rates of vWF collagen-binding activity were 81.11%, 87.81%, 86.15%, 73.73%, and 73.72% under the same dose conditions. Conclusion: Considering both inactivation efficacy and functional preservation while ensuring safety and effectiveness, 100-150 J/m represents the optimal inactivation dose.

OBJECTIVE To establish a clinical pharmaceutical pathway of anti-infective therapy for high-risk populations of antibiotic-associated encephalopathy （AAE）， and analyze its application effects. METHODS Clinical pharmacists developed the “AAE High-Risk Population Screening Form” and “Antibiotic AAE Risk Comparison Form” based on literature and expert opinions， and established the “Clinical Pharmaceutical Pathway of Anti-infective Treatment for AAE High-Risk Population” in our hospital. A prospective， non-randomized controlled study was conducted from May 2023 to April 2024， including 50 cases in the observation group and 50 cases in the control group among patients with pulmonary infections admitted to the Dept. of Internal Medicine in our hospital. The observation group was involved in the development of an anti-infective treatment following the clinical pharmaceutical pathway by clinical pharmacists， while the control group received routine anti-infective treatment by clinical physicians. The occurrence of AAE， the rational antibiotic drug use， and the effectiveness of initial anti-infective treatment in the two groups were observed， and the intervention measures and outcomes of AAE cases were summarized. RESULTS The anti-infective treatment clinical pharmaceutical pathway for AAE high-risk population was preliminarily established in our hospital. The analysis of the application effects showed that there was 1 case of AAE in the observation group and 8 cases in the control group， with a significantly lower incidence of AAE in the observation group than in the control group； the rational antibiotic drug use and the effectiveness of initial anti-infective treatment in the observation group were both significantly superior to those in the control group （P＜0.05）. Drug withdrawal and dressing change were the preferred effective intervention measures for AAE， and encephalopathy treatment drugs could be used as auxiliary measures for symptom relief. Timely and effective intervention was conducive to rapid symptom relief， with a total improvement rate of AAE of 88.89%. CONCLUSIONS The anti-infective treatment clinical pharmaceutical pathway for AAE high-risk population can effectively prevent the occurrence of AAE as well as contribute to promoting rational drug use and the effectiveness of initial anti-infection plans and strengthening treatment outcomes.

Parasitic infection has the characteristics of both endemic and infectious diseases, and its incidence is regional and has the attribute of transmission. Although the incidence of parasitic infection due to blood transfusion is low, it is still reported in developing countries and regions. With the development of society and economy, the travel of blood donors between different countries or regions increases, and the chances of blood recipients being exposed to parasitic infections also increase. Research on transfusion-transmitted parasites is limited compared to transfusion-transmitted viruses and bacteria. Serologic testing is not available in most countries to screen blood donors for transfusion-borne parasites such as Plasmodium, Babesia, Trypanosoma cruzi, Leishmania, Toxoplasma gondii and Microfilariae. In order to have a more comprehensive understanding of transfusion-transmitted parasites, this paper reviews the current situation of transfusion-transmitted parasites from the perspectives of epidemiological characteristics, detection techniques, and prevention and control methods of transfusion-transmitted parasites.

Diabetic peripheral neuropathy (DPN) is the common chronic complication of diabetes, which can lead to foot ulcers, gangrene, and amputation in severe cases, seriously affecting their quality of life. DPN belongs to the category of "arthralgia", "hemorrhoids" and other categories of TCM, and the main pathogenesis is the deficiency of qi and blood, yin and yang, and the obstruction of the meridians by phlegm and stasis. Clinically, DPN is more common with qi deficiency and blood stasis syndrome. Based on the theory of "qi meridian constant communication" in the Huang Di Nei Jing, this article proposed that for patients with DPN with qi deficiency and blood stasis syndrome, the treatment should be based on the principle of "invigorating qi and activating blood circulation, dissolving stasis and arthralgia", so that the patients' qi meridian can be accessible, delay the disease progression, and provide reference for the TCM treatment of DPN.

Objective:To explore the clinical efficacy and safety analysis of a novel laser localization technology assisted percutaneous puncture of trigeminal nerve microsphere capsule compression surgery for the treatment of primary trigeminal neuralgia.Methods:A retrospective selection was conducted on 63 patients with primary trigeminal neuralgia who underwent percutaneous puncture of the trigeminal nerve microsphere capsule compression surgery at the First Hospital of Hunan University of Chinese Medicine from January 2020 to December 2021. According to different surgical methods, they were divided into a new laser localization assisted puncture group (observation group) of 32 cases and a traditional barehanded localization puncture group (control group) of 31 cases. An analysis was conducted on the surgical time, puncture time, puncture frequency, intraoperative exposure to radiation, number of cases of poor balloon formation, and clinical efficacy within 6 months after surgery for two groups of patients. The prognosis of the patients was followed up at 6 months after surgery.Results:The surgical time, puncture time, puncture frequency, and intraoperative exposure of the observation group were all less than those of the control group, and the differences were statistically significant (all P<0.05). There was no statistically significant difference ( P>0.05) in the number of cases of poor balloon angioplasty between the observation group and the control group, as well as the pain score grading of the Barlow Neurological Institute (BNI) on the first day after surgery. Within 6 months after surgery, there was no statistically significant difference in the incidence of facial numbness, diplopia, masseter weakness, perilabial herpes, and recurrent pain between the two groups of patients (all P>0.05). Conclusions:Laser positioning technology can assist in precise puncture of the foramen ovale and accurate placement of balloons based on surgical experience, which helps to improve surgical safety, reduce postoperative complications and intraoperative radiation dose, and achieve satisfactory short-term follow-up results.
