ObjectiveTo evaluate the effects of Tongnaoyin on the blood-brain barrier status and neurological impairment in acute ischemic stroke （AIS） patients with the syndrome of phlegm-stasis blocking collaterals by dynamic contrast-enhanced magnetic resonance imaging （DCE-MRI）. MethodsA total of 63 patients diagnosed with AIS in the Jiangsu Province Hospital of Chinese Medicine from October 2022 to December 2023 were enrolled in this study. According to random number table method，the patients were assigned into a control group （32 cases） and an observation group （31 cases）. The control group received conventional Western medical treatment，and the observation group took 200 mL Tongnaoyin after meals，twice a day from day 2 of admission on the basis of the treatment in the control group. After 7 days of treatment，the patients were examined by DCE-MRI. The baseline data for two groups of patients before treatment were compared. The National Institute of Health Stroke Scale （NIHSS） score and modified Rankin Scale （mRS） score were recorded before treatment and after 90 days of treatment for both groups. The rKtrans，rKep，and rVe values were obtained from the region of interest （ROI） of the infarct zone/mirror area and compared between the two groups. ResultsThere was no significant difference in the NIHSS or mRS score between the two groups before treatment. After 90 days of treatment，the NIHSS and mRS scores declined in both groups，and the observation group had lower scores than the control group （P<0.05）. After treatment，the rKtrans and rVe in the observation group were lower than those in the control group （P<0.01）. ConclusionCompared with conventional Western medical treatment alone，conventional Western medical treatment combined with Tongnaoyin accelerates the repair of the blood-brain barrier in AIS patients，thereby ameliorating neurological impairment after AIS to improve the prognosis.

Objective: Data on syncopal donation-related vasovagal reaction (DRVR) collected from 74 blood centers between 2020 and 2023 was statistically analyzed to provide a reference for developing preventive strategies against syncopal DRVR. Methods: Data on blood donation adverse reactions and basic information of donors from 2020 to 2023 were collected through the information management system at monitoring sentinel sites. Statistical analysis was performed on the following aspects of syncopal DRVR: characteristics of donors who experienced syncope, reported incidence, triggers, duration, presence and occurrence time of syncope-related trauma, clinical management including outpatient and inpatient treatment, and severity grading. Results: From 2020 to 2023, 45 966 donation-related adverse reactions were recorded. Of these, 1 665 (3.72%) cases were syncopal DRVR. The incidence of syncopal DRVR decreased with age, being the highest in the 18-22 age group. Incidence was significantly higher in female donors than male donors, in first-time donors than repeat donors, and in university and individual donors than group donors (all P<0.05). There was no statistically significant difference among different blood donation locations (P>0.05). The top three triggers were tension, fatigue, and needle phobia or fear of blood. Among syncopal DRVR cases, 60.36% occurred during blood collection, 87.63% lasted for less than 60 seconds, and 5.05% were accompanied by trauma. Notably, 57.14% of these traumas occurred after donor had left the blood collection site. Syncope severity was graded based on required treatment: grade 1 (fully recovered without treatment, 95.50%); grade 2 (recovered after outpatient treatment, 4.02%); and grade 3 (recovered after inpatient treatment, 0.48%). Conclusion: By analyzing the data of syncopal DRVR cases, it is possible to provide a reference for formulating blood donor safety policies.

OBJECTIVE: To analyze the distribution characteristics of glucose-6-phosphate-dehydrogenase (G6PD) mutations and their enzyme activity in newborns patients with G6PD deficiency in Guilin region. METHODS: From July 2022 to July 2024, umbilical cord blood samples from 4 554 newborns in Guilin were analyzed for G6PD mutations using fluorescence PCR melting curve analysis. Enzyme activity was detected in 4 467 cases using the rate assay. RESULTS: Among 4 467 newborns who underwent G6PD activity testing, 162 newborns (3.63%) were identified as G6PD-deficient, including 142 males (6.04%) and 20 females (0.94%), the prevalence of G6PD deficiency was significantly higher in males than in females (P < 0.001). Genetic analysis of 4 554 newborns detected G6PD mutations in 410 cases (9%), including 171 males (7.13%) and 239 females (11.09%), with a significantly higher mutation detection rate in females than in males (P < 0.001). A total of nine single mutations and four compound heterozygous mutations were identified. The most common mutations were c.1388G>A (33.66%), c.1376G>T (23.66%) and c.95A>G (16.34%). Among newborns who underwent both enzyme activity and genetic mutation testing, males with G6PD mutations had significantly lower enzyme activity than that of females with G6PD mutations(P < 0.001). Specifically, among newborns carrying the mutations c.1388G>A, c.1376G>T, c.95A>G, c.1024C>T or c.871G>A, males consistently exhibited lower enzymatic activity than females with the same mutations (P < 0.001). Furthermore, in male G6PD-deficient newborns, the enzyme activity levels in those carrying c.1388G>A, c.1376G>T, c.95A>G, c.1024C>T, or c.871G>A were lower than those in both the control group and the c.519C>T group (P < 0.05). CONCLUSION This study provides a comprehensive profile of G6PD deficiency incidence and mutation spectrum in the Guilin region. By analyzing enzyme activity and genetic mutation results, this study provides insights into potential intervention strategies and personalized management approaches for the prevention and treatment of neonatal G6PD deficiency in the region.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective:To investigate associations between cardiac biomarkers with stroke severity and short-term outcome in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to the Affiliated Hospital of Qingdao University from June 2018 to February 2024 whose etiological classification was large artery atherosclerosis (LAA), small vessel occlusion (SVO) or cardioembolism (CE) were included retrospectively. According to the National Institutes of Health Stroke Scale score at admission, patients were divided into mild stroke group (≤8) and moderate to severe stroke group (>8). According to the modified Rankin Scale score at discharge, patients were divided into good outcome group (≤2) and poor outcome group (>2). Multivariate logistic regression analysis was used to determine the independent correlation between cardiac biomarkers and short-term outcome. The predictive value of cardiac biomarkers for poor outcome in patients with AIS and different stroke etiology subtypes were evaluated using receiver operating characteristic (ROC) curves. Results:A total of 2 151 patients with AIS were enrolled, including 1 256 males (58.4%), aged 67.40±11.34 years. 1 079 patents were LAA type (50.2%), 679 were SVO type (31.6%), and 393 were CE type (18.3%); 1 223 were mild stroke (56.86%) and 928 (43.14%) were moderate to severe stroke; 1 357 patients (63.09%) had good short-term outcome, and 794 (36.91%) had poor short-term outcome. Multivariate logistic regression analysis showed that N-terminal pro-B type natriuretic peptide (NT-proBNP), NT-proBNP/creatine kinase (CK) isoenzyme MB (CK-MB) ratio, and CK-MB/CK ratio were independent risk factors for poor short-term outcome. ROC curve analysis shows that the CK-MB/CK ratio had a higher predictive value for short-term poor outcome in patients with AIS (the area under the curve, 0.859, 95% confidence interval 0.839-0.879). Various cardiac biomarkers had a higher predictive value for short-term outcome of CE type and LAA type, but the predictive value for short-term outcome of SVO type was lower. Conclusions:Cardiac biomarkers are associated with the severity and poor outcome of AIS. NT-proBNP/CK-MB and CK-MB/CK ratios have higher predictive value for short-term poor outcome of AIS, especially in patients with CE type.

ObjectiveTo investigate the changes in cerebral blood perfusion in patients with acute cerebral infarction after taking Tongnaoyin， a traditional Chinese medicine， based on head and neck computed tomography （CT） angiography （CTA） combined with brain CT perfusion imaging （CTP）. MethodA total of 240 patients with cerebral infarction of phlegm and blood stasis syndrome treated in Jiangsu Province Hospital of Traditional Chinese Medicine from March 2018 to September 2023 were randomly divided into a control group （99 cases） and a Tongnaoyin group （141 cases）. Based on the guidelines， the control group was treated with conventional treatment such as anti-aggregation， anticoagulation， lipid-lowering and plaque stabilization， brain protection， and supportive treatment. The Tongnaoyin group was treated with Tongnaoyin of 200 mL in warm conditions in the morning and evening on the basis of the control group. Both groups underwent CTA combined with CTP within 24 hours after admission， and they were reexamined by CTA and CTP in the sixth month after admission. The degree of intracranial artery stenosis was determined according to the North American Symptomatic Carotid Endarterectomy Trial （NASCET） method. The relative cerebral blood volume （rCBV）， relative cerebral blood flow （rCBF）， mean transit time （MTT）， and time to peak （TTP） of the lesion area before and after treatment were compared. The adverse outcomes of the two groups within six months after discharge were compared. ResultCompared with the group before treatment， the degree of vascular stenosis in the Tongnaoyin group was significantly reduced， and the difference was statistically significant （Z=105.369，P<0.05）. Compared with the control group after treatment， the improvement rate of vascular stenosis in the Tongnaoyin group was higher （χ²=84.179，P<0.01）， and the curative effect was better.After treatment， the rCBV and rCBF of patients in the Tongnaoyin group were significantly increased， and the difference was statistically significant （P<0.01）. MTT and TTP showed a trend of shortening， but the difference was not statistically significant. There was no statistically significant difference in rCBV， rCBF， MTT， and TTP in the control group. Compared with those in the control group after treatment， the rCBV and rCBF in the Tongnaoyin group were significantly increased， while MTT and TTP were significantly reduced （P<0.01）. After six months of discharge， the risk of poor prognosis in the Tongnaoyin group was significantly reduced compared with the control group （P<0.05）. ConclusionTongnaoyin has a good effect on improving cerebral blood perfusion in patients with acute cerebral infarction. It can be used as an effective supplement for the conventional treatment of ischemic stroke to improve clinical efficacy.

Objective To investigate the clinical efficacy of Xuanfei Tongluo Pingchuan Decoction in treating patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)and to explore its regulatory mechanism on immune function and inflammatory response.Methods A retrospective study was conducted in 122 patients with AECOPD of phlegm-stasis obstructing lung type,and the patients were divided into an observation group and a control group according to the therapy,with 61 patients in each group.The control group was treated with conventional western medicine,and the observation group was treated with Xuanfei Tongluo Pingchuan Decoction on the basis of treatment for the control group.The treatment lasted for 14 days.Before and after treatment,the patients of the two groups were observed in the changes of pulmonary function indicators,6-minute walking distance(6MWD),COPD Assessment Test(CAT)scores,immune function indicators,and serum inflammatory factors.After treatment,the clinical efficacy and the overall occurrence rate of the adverse reactions were compared between the two groups.Results(1)After 14 days of treatment,the total effective rate of the observation group was 95.08%(58/61),and that of the control group was 77.05%(47/61).The intergroup comparison showed that the therapeutic effect of the observation group was significantly superior to that of the control group(P＜0.01).(2)After treatment,pulmonary function indexes such as the forced expiratory volume in one second(FEV1),forced vital capacity(FVC),and peak expiratory flow(PEF)of the two groups were significantly improved compared with those before treatment(P＜0.05),and the effect on improving all pulmonary function indexes in the observation group was significantly superior to that in the control group(P＜0.01).(3)After treatment,the 6MWD of the two groups were significantly higher(P＜0.05)and the CAT scores were significantly lower than those before treatment(P＜0.05),and the observation group was significantly superior to the control group in terms of improving the 6MWD and decreasing CAT scores(P＜0.01).(4)After treatment,the levels of immune function indicators of T lymphocyte subsets CD4+ and CD4+/CD8+ in the two groups were significantly higher than those before treatment(P＜0.05),and CD8+ level was significantly lower than that before treatment(P＜0.05),and the observation group had stronger effect on increasing T lymphocyte subsets CD4+ and CD4+/CD8+ levels and on decreasing CD8+ level than the control group(P＜0.01).(5)After treatment,the serum levels of inflammatory factors C-reactive protein(CRP)and tumor necrosis factor alpha(TNF-α)in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the effect on lowering the levels of serum CRP and TNF-α in the observation group was significantly superior to that in the control group(P＜0.01).(6)During the trial,the total incidence of adverse reactions in the observation group was 3.28%(2/61)and that in the control group was 6.56%(4/61),and the intergroup comparison showed that the difference was not statistically significant between the two groups(P＞0.05).Conclusion Xuanfei Tongluo Pingchuan Decoction can effectively alleviate the symptoms of cough and expectoration in AECOPD patients,improve the lung function and immune function,and reduce the inflammatory response.During the treatment,no obvious adverse reactions occur and the therapy is safe and effective.

Objective:To explore the influencing factors of early postoperative complications after radical resection of congenital choledochal cyst (CCC) in a single center and provide some clinical basis and guidance for reducing postoperative complications.Methods:Case control study.Clinical data of 124 children (29 boys and 95 girls) with CCC diagnosed and radically treated at the Affiliated Hospital of Zunyi Medical University from September 2010 to October 2019 were analyzed.According to postoperative complications (bile leakage, gastrointestinal anastomotic fistula, bleeding, incision dehiscence, cholangitis, abdominal infection, pancreatitis, and lymphatic fistula), these children were divided into the complication group (group A) and non-complication group (group B). Age, laboratory indicators[preoperative white blood cell (WBC) count, hemoglobin, glutamic pyruvic transaminase, prealbumin, and postoperative albumin], and clinical factors, such as operation method, operation time, intraoperative blood loss, cyst type, cyst diameter, hepatic duct diameter, abdominal operation history, biliary sludge and calculus, hepatic duct anatomic variation, and pancreaticobiliary maljunction were statistically analyzed between the two groups.The t-test was performed for normal distribution of the measurement data, and the non-parametric rank sum test for non-normal distribution.Multivariate analysis was made using Logistic regression. Results:Among the 124 children, 25(20.16%) had complications, and 99(79.84%) had no complications.Bile leakage occurred in 14 children (11.29%), of whom 7 received operation again and 7 received conservative treatment.Gastrointestinal anastomotic fistula occurred in 2 children (1.61%), of whom 1 was re-operated and 1 was cured conservatively.One child (0.81%) was complicated with bleeding and cured by re-operation.Two children (1.61%) were complicated with incision dehiscence, of whom 1 was cured by re-operation and 1 was cured by conservative treatment.Cholangitis in 2 children (1.61%), abdominal infection in 2 children (1.61%), pancreatitis in 1 child (0.81%), and lymphatic fistula in 1 child (0.81%) were all conservatively cured.No significant difference was found in non-normal distribution indicators-age and WBC count-between the two groups (all P>0.05). Blood loss volume and cyst diameter were significantly different between the two groups (all P<0.05). Postoperative albumin[(27.84±4.62) g/L vs.(32.45±3.72) g/L] meeting the normal distribution showed a statistically significant difference between the two groups ( t=5.254, P<0.05). Logistic multivariate regression analysis suggested that preoperative anemia ( OR=7.922, 95% CI: 1.468-42.757) and biliary sludge and calculus ( OR=1.295, 95% CI: 1.075-4.359) were independent risk factors for postoperative complications; postoperative albumin ( OR=0.055, 95% CI: 0.012-0.244) was a protective factor for postoperative complications, and the differences were statistically significant (all P<0.05). Conclusions:The larger the cyst diameter, the more the intraoperative bleeding, and the higher the risk of operation.Treating anemia before operation, clearing sludge in the hepatic duct during operation, reducing bleeding, and strengthening the monitoring of albumin and hemoglobin during the perioperative period can prevent and reduce early complications after radical resection of CCC in children.
