Pharmaceutical cocrystals is an advanced technology to improve the physicochemical and biological properties of drugs. However, there are few studies on the in vivo metabolism of pharmaceutical cocrystals. In this study, the pharmacokinetics of wogonin cocrystal in normal rats was further studied on the basis of the previous preparation of wogonin-aloperine cocrystal. Firstly, an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was established for simultaneous determination of wogonin and its metabolite wogonoside in rat plasma, and to investigate the methodology. The method was applied to the pharmacokinetic study of wogonin-aloperine cocrystal (Wog-Alop) in rats. The results showed that wogonin and its metabolite wogonoside had a good linear relationship in the range of 1-800 ng·mL^-1, and the precision, accuracy, matrix effect and stability in this range met the requirements of biological analysis. Compared with direct administration of wogonin, the C_max of wogonin and its metabolite in rats increased to 7.44-fold and 9.15-fold, AUC_0-t increased to 1.67-fold and 3.72-fold, and oral bioavailability of wogonin increased to 187.66% after cocrystal administration. Wog-Alop cocrystal can significantly improve the C_max, AUC, and oral bioavailability of wogonin and its metabolite, which provides a new perspective for the clinical application of wogonin. This study was approved by the Experimental Animal Ethics Review Committee of Beijing University of Chinese Medicine (approval number: BUCM-2023032307-1148).

Objective To investigate the attributable risk(AR)of Acinetobacter baumannii(AB)infection in criti-cally ill patients.Methods A multicenter retrospective cohort study was conducted among adult patients in inten-sive care unit(ICU).Patients with AB isolated from sterile body fluid and confirmed with AB infection in each cen-ter were selected as the infected group.According to the matching criteria that patients should be from the same pe-riod,in the same ICU,as well as with similar APACHE Ⅱ score(±5 points)and primary diagnosis,patients who did not infect with AB were selected as the non-infected group in a 1:2 ratio.The AR was calculated.Results The in-hospital mortality of patients with AB infection in sterile body fluid was 33.3％,and that of non-infected group was 23.1％,with no statistically significant difference between the two groups(P=0.069).The AR was 10.2％(95％CI:-2.3％-22.8％).There is no statistically significant difference in mortality between non-infected pa-tients and infected patients from whose blood,cerebrospinal fluid and other specimen sources AB were isolated(P＞0.05).After infected with AB,critically ill patients with the major diagnosis of pulmonary infection had the high-est AR.There was no statistically significant difference in mortality between patients in the infected and non-infec-ted groups(P＞0.05),or between other diagnostic classifications.Conclusion The prognosis of AB infection in critically ill patients is highly overestimated,but active healthcare-associated infection control for AB in the ICU should still be carried out.

Objective To observe the clinical effect of Dongjing Tiaoshen Comprehensive Therapy combined with computerized cognitive behavioral therapy for insomnia(CCBT-I)in the treatment of chronic insomnia patients with liver depression and spleen deficiency syndrome.Methods A total of 60 patients with chronic insomnia of liver depression and spleen deficiency type were randomly divided into observation group and control group,30 cases in each group.Both groups of patients were treated with CCBT-I as the basic treatment,the observation group was additionally treated with Dongjing Tiaoshen Comprehensive Therapy,i.e.,mind-regulating acupuncture therapy combined with regular aerobic exercises and Dantian Qigong exercises,and the control group was additionally treated with cranial electrotherapy stimulation.The course of treatment for the two groups covered 4 weeks.The changes of Pittsburgh Sleep Quality Index(PSQI)score,Self-rating Anxiety Scale(SAS)score and Self-rating Depression Scale(SDS)score in the two groups were observed before and after treatment,and the clinical efficacy of the two groups was evaluated after treatment.Results(1)After 4 weeks of treatment,the total effective rate of the observation group was 86.67%(26/30),and that of the control group was 70.00%(21/30).The intergroup comparison(tested by rank sum test)showed that the curative effect of the observation group was significantly superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)After treatment,the PSQI scores of the two groups were significantly lower than those before treatment(P＜0.05),and the decrease of PSQI scores in the observation group was significantly superior to that in the control group,the difference being statistically significant(P＜0.05).(3)After treatment,the SAS and SDS scores of the two groups were significantly lower than those before treatment(P＜0.05),and the decrease of SAS and SDS scores in the observation group tended to be superior to that in the control group,but there was no significant difference between the two groups(P＞0.05).Conclusion For the treatment of chronic insomnia of liver depression and spleen deficiency type,the combination of Dongjing Tiaoshen Comprehensive Therapy with CCBT-I can significantly improve the sleep quality,relieve anxiety and depression,and improve the quality of life of the patients,which exerts significant efficacy.

Objective:The incidence of infections in patients with malignant hematologic diseases is extremely high and significantly affects their prognosis.Identifying early and precise biomarkers for infection is crucial for guiding the treatment of infections in these patients.Previous studies have shown that procalcitonin(PCT)can serve as an early diagnostic marker for bloodstream infections in patients with malignant hematologic diseases.This study aims to compare serum PCT levels in these patients with different pathogens,disease types,infection sites,and severity levels. Methods:Clinical data and laboratory results of infected patients with malignant hematologic diseases treated at the Department of Hematology,the Third Xiangya Hospital of Central South University from January 2018 to August 2023 were collected.General patient information was retrospectively analyzed.Serum PCT levels were compared among patients with different pathogens,types of malignant hematologic diseases,infection sites,and infection severity;Receiver operator characteristic(ROC)curves were used to determine the cut-off values and diagnostic value of serum PCT levels in diagnosing bloodstream infections versus local infections and severe infections versus non-severe infections.Mortality rates after 4-7 days of anti-infective treatment were compared among groups with rising,falling,and unchanged PCT levels. Results:A total of 526 patients with malignant hematologic diseases were included.The main pathogens were Gram-negative bacteria(272 cases,51.7%),followed by Gram-positive bacteria(120 cases,22.8%),fungi(65 cases,12.4%),viruses(23 cases,4.4%),and mixed pathogens(46 cases,8.7%).The main types of malignant hematologic diseases were acute myeloid leukemia(216 cases,41.1%),acute lymphoblastic leukemia(107 cases,20.3%),and lymphoma(93 cases,17.7%).Granulocyte deficiency was present in 68.3%(359 cases)of the patients during infection,with severe infection in 24.1%(127 cases).Significant differences in serum PCT levels were found among patients with different types of pathogens(P<0.001),with the highest levels in Gram-negative bacterial infections.Significant differences in serum PCT levels were also found among patients with different types of malignant hematologic diseases(P<0.05),with the highest levels in lymphoma patients.Serum PCT levels were significantly higher in systemic infections and severe infections compared to local infections and non-severe infections(both P<0.001).ROC curve analysis showed that the cut-off values for diagnosing bloodstream infections and severe infections were 0.22 and 0.28 ng/mL,with areas under the curve of 0.670 and 0.673,respectively.After 4-7 days of anti-infective treatment,the mortality rates of the PCT declining,PCT unchanged,and PCT rising groups were 11.9%,21.2%,and 35.7%,respectively,and pairwise comparisons were statistically significant(all P<0.05). Conclusion:PCT can be used as an auxiliary indicator for early identification of different pathogens,infection sites,and severity levels in patients with malignant hematologic diseases combined with infections.Dynamic monitoring of PCT levels after empirical antibiotic treatment provides important guidance for assessing patient's prognosis.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To investigate the changing distribution and antibiotic resistance profiles of clinical isolates of Staphylococcus in hospitals across China from 2015 to 2021.Methods Antimicrobial susceptibility testing was conducted for the clinical isolates of Staphylococcus according to the unified protocol of CHINET(China Antimicrobial Surveillance Network)using disk diffusion method and commercial automated systems.The CHINET antimicrobial resistance surveillance data from 2015 to 2021 were interpreted according to the 2021 CLSI breakpoints and analyzed using WHONET 5.6.Results During the period from 2015 to 2021,a total of 204,771 nonduplicate strains of Staphylococcus were isolated,including 136,731(66.8％)strains of Staphylococcus aureus and 68,040(33.2％)strains of coagulase-negative Staphylococcus(CNS).The proportions of S.aureus isolates and CNS isolates did not show significant change.S.aureus strains were mainly isolated from respiratory specimens(38.9±5.1)％,wound,pus and secretions(33.6±4.2)％,and blood(11.9±1.5)％.The CNS strains were predominantly isolated from blood(73.6±4.2)％,cerebrospinal fluid(12.1±2.5)％,and pleural effusion and ascites(8.4±2.1)％.S.aureus strains were mainly isolated from the patients in ICU(17.0±7.3)％,outpatient and emergency(11.6±1.7)％,and department of surgery(11.2±0.9)％,whereas CNS strains were primarily isolated from the patients in ICU(32.2±9.7)％,outpatient and emergency(12.8±4.7)％,and department of internal medicine(11.2±1.9)％.The prevalence of methicillin-resistant strains was 32.9％in S.aureus(MRSA)and 74.1％in CNS(MRCNS).Over the 7-year period,the prevalence of MRSA decreased from 42.1％to 29.2％,and the prevalence of MRCNS decreased from 82.1％to 68.2％.MRSA showed higher resistance rates to all the antimicrobial agents tested except trimethoprim-sulfamethoxazole than methicillin-susceptible S.aureus(MSSA).Over the 7-year period,MRSA strains showed decreasing resistance rates to gentamicin,rifampicin,and levofloxacin,MRCNS showed decreasing resistance rates to gentamicin,erythromycin,rifampicin,and trimethoprim-sulfamethoxazole,but increasing resistance rate to levofloxacin.No vancomycin-resistant strains were detected.The prevalence of linezolid-resistant MRCNS increased from 0.2％to 2.3％over the 7-year period.Conclusions Staphylococcus remains the major pathogen among gram-positive bacteria.MRSA and MRCNS were still the principal antibiotic-resistant gram-positive bacteria.No S.aureus isolates were found resistant to vancomycin or linezolid,but linezolid-resistant strains have been detected in MRCNS isolates,which is an issue of concern.

A total of 360 healthy 26 week old Huaixiang hens were randomly divided into 10 groups,of which,five groups were reared at normal temperature(NC,NT1,NT2,NT3,NT4)and other five groups were reared at high temperature(HC,HT1,HT2,HT3,HT4),all chickens were feed with 0,4,6,8,10 mg/kg canthaxanthin(CX)respectively.The pre-test period was 2 weeks and the main test period was 9 weeks.The results showed that high temperature reduced the egg pro-duction rate(P＜0.05),led to damage and hemorrhage in the ovaries,decreased the activity of su-peroxide dismutase(SOD),glutathione peroxidase(GSH-Px)in the serum and the ovaries(P＜0.05),decreased the levels of FSH,LH,P4,and E2(P＜0.05),decreased the expression of FSHR,LHR,ER,and PR(P＜0.05),and increased the levels of malonaldehyde(MDA)(P＜0.05)in the ovaries.Addition of CX increased the egg production rate(P＜0.05),increased the activity of serum and ovarian SOD and GSH-Px enzymes(P＜0.05),decreased the content of serum and ovarian MDA(P＜0.05)),increased the ovarian levels of FSH,LH,P4,E2(P＜0.05),and increased the o-varian expression of FSHR,LHR,ER,and PR(P＜0.05)in Huaixiang chickens at normal and high temperature environmental conditions,respectively.Among them,the highest egg production rate,the strongest antioxidant capacity of serum and ovarian tissues,the best integrity of ovarian tis-sues,ovarian reproductive hormone secretion and expression of reproductive hormone receptors were observed in Huaixiang chickens when 6 mg/kg of CX was added to the diet under normal temperature and when 8 mg/kg CX was added to the diet under high temperature conditions.The results showed that under normal and high temperature conditions,adding CX to the diet signifi-cantly increased the antioxidant capacity of serum and ovaries,alleviated the damage of ovary,pro-moted the secretion of reproductive hormone and the expression of reproductive hormone recep-tors,and increased egg production rate.Dietary supplemented with CX could not restore the dam-age and repair of ovarian tissue,the secretion of reproductive hormone and receptor to normal tem-perature level.The effects of CX on egg production rate,ovarian tissue structure,reproductive hor-mone and receptor expression in chickens were affected by the environmental temperature.When the egg production rate,antioxidant capacity of ovarian tissues,reproductive hormone levels and receptor expression of Huaixiang chickens were optimal,the amount of CX in high temperature en-vironment was more than that of the dose in normal temperature environment.

Objective:To explore the effect of shikonin on autophagy and apoptosis of human promyelocytic leukemia cells and its possible mechanism.Methods:Human promyelocytic leukemia cells NB4 in the logarithmic growth phase were divided into control group(untreated NB4 cells),shikonin group(0.3 μmol/L shikonin treatment),740Y-P group(15 μmol/L PI3K/Akt/mTOR pathway activator 740Y-P treatment),shikonin+740Y-P group(0.3 μmol/L shikonin and 15 μmol/L 740Y-P co-treatment),after 24 hours of treatment,the cells were used for subsequent experiments.CCK-8 method was used to detect cell viability,monodansylcadaverine(MDC)staining to detect the aggregation of autophagic vesicles,flow cytometry to detect cell apoptosis,and Western blot to detect the expression of Beclinl,LC3,p62,Bax,cleaved caspase-3,Bcl-2 and PI3K/Akt/mTOR pathway related proteins.Results:Compared with the control group,the purple punctate fluorescence intensity,apoptosis rate,Beclinl,LC3-Ⅱ/LC3-Ⅰ,cleaved caspase-3,and Bax protein expression in NB4 cells were increased in the shikonin group,while OD450 value(24,48 h)and the expressions of Bcl-2 and p62 proteins were decreased(all P＜0.05).Compared with the control group,the purple punctate fluorescence intensity,apoptosis rate,Beclin1,LC3-Ⅱ/LC3-1,cleaved caspase-3,and Bax protein expression in NB4 cells were decreased,while OD450 value(24,48 h)and the expressions of Bcl-2 and p62 proteins were increased in the 740Y-P group(all P＜0.05).Compared with the shikonin group,the purple punctate fluorescence intensity,apoptosis rate,Beclinl,LC3-Ⅱ/LC3-1,cleaved caspase-3,and Bax protein expression in NB4 cells were decreased,while OD450 value(24,48 h)and the expressions of Bcl-2 and p62 proteins were increased in the shikonin+740Y-P group(all P＜0.05).Compared with the control group,the expression of PI3K/Akt/mTOR pathway related proteins p-PI3K,p-Akt,and p-mTOR in NB4 cells were significantly decreased in the shikonin group,while those in the 740Y-P group were increased(all P＜0.05).Compared with the shikonin group,the expressions of p-PI3K,p-Akt,and p-mTOR proteins in NB4 cells were significantly increased in the shikonin+740Y-P group(all P＜0.05).Conclusion:Shikonin may promote autophagy and apoptosis of NB4 cells by inhibiting PI3K/Akt/mTOR pathway.

AIM To investigate the effects of Xinyue Capsules on the expression of glycerophospholipid metabolizing enzymes in isoproterenol(ISO)-induced rat heart tissue and primary myocardial cells of neonatal rats.METHODS The SD rats were randomly divided into the normal group,the model group,the Xinyue Capsules intervention group and Xinyue Capsules control group,with 8 rats in each group.The rat model of cardiac hypertrophy was established by 14 days consecutive intraperitoneal injection of ISO(30 mg/kg).Prior to the modeling,once daily administration of 0.393 g/kg Xinyue Capsules was given by gavage from 3 days in advance to the end of the experiment.After the last administration,the procurement of blood from abdominal aorta,the left and right ventricles were processed.And the rats had their indices levels of the heart,the left ventricle and the right ventricle measured;their pathomorphological changes of myocardial tissue observed using HE staining;their expressions of cardiac hypertrophy-related myocardial embryonic genes ANP,β-MHC and α-SKA mRNA detected using RT-qPCR method;and their serum TC,TG,LDL-C and HDL-C levels detected by biochemical method.In in vitro experiment,the neonatal rat model of myocardial hypertrophy was induced by exposure to ISO 1 μmol/L for 24 h.The investigation of the effect of Xinyue Capsules 12.5 μg/mL on ISO-induced myocardial hypertrophy was conducted by detection of myocardial cell area,embryo genes related to cardiac hypertrophy and myocardial cells protein cuntent.The further anti-cardiac hypertrophy mechanism of Xinyue Capsules research was conducted using RT-qPCR and Western blot to detect the gene and protein expressions of phospholipase A2(PLA2G6),phospholipase A1 member A(PLA1A)and lecithin cholesterol acyltransferase(LCAT)in left ventricle tissue and myocardial cells of each group.RESULTS The in vivo experimental result showed that compared with the normal group,the model group displayed increased indices levels of the heart,the left ventricle and the right ventricle and cross-sectional area of left ventricular myocytes(P＜0.05);and up-regulated expressions of ANP,β-MHC,α-SKA mRNA and PLA2G6,PLA1A and LCAT mRNA and proteins in the left ventricle(P＜0.05);and increased levels of serum TC,TG and LDL-C(P＜0.05);and decreased HDL-C level(P＜0.05).However,the intervention of Xinyue Capsules inhibited the changes of the aforementioned indices(P＜0.05).The in vitro experimental result revealed that Xinyue Capsules inhibited the ISO-induced increases of myocardial cell surface area and myocardial cell protein level,the up-regulation of ANP,β-MHC,α-SKA mRNA expressions and the PLA2G6,PLA1A,LCAT mRNA and protein expressions as well(P＜0.05).CONCLUSION Xinyue Capsules can improve the ISO-induced cardiac hypertrophy in rats,and its mechanism may be associated with its regulation upon the expressions of glycerophospholipid metabolism-related enzymes PLA2G6,PLA1A and LCAT.
