Jiuwei Xifeng Granules have become a Chinese patent medicine in the market. Because the formula contains Os Draconis, a top-level protected fossil of ancient organisms, the formula was to be improved by replacing Os Draconis with Ostreae Concha. To evaluate whether the improved formula has the same effectiveness and safety as the original formula, a randomized, double-blind, parallel-controlled, equivalence clinical trial was conducted. This study enrolled 288 tic disorder(TD) of children and assigned them into two groups in 1∶1. The treatment group and control group took the modified formula and original formula, respectively. The treatment lasted for 6 weeks, and follow-up visits were conducted at weeks 2, 4, and 6. The primary efficacy endpoint was the difference in Yale global tic severity scale(YGTSS)-total tic severity(TTS) score from baseline after 6 weeks of treatment. The results showed that after 6 weeks of treatment, the declines in YGTSS-TSS score showed no statistically significant difference between the two groups. The difference in YGTSS-TSS score(treatment group-control group) and the 95%CI of the full analysis set(FAS) were-0.17[-1.42, 1.08] and those of per-protocol set(PPS) were 0.29[-0.97, 1.56], which were within the equivalence boundary [-3, 3]. The equivalence test was therefore concluded. The two groups showed no significant differences in the secondary efficacy endpoints of effective rate for TD, total score and factor scores of YGTSS, clinical global impressions-severity(CGI-S) score, traditional Chinese medicine(TCM) response rate, or symptom disappearance rate, and thus a complete evidence chain with the primary outcome was formed. A total of 6 adverse reactions were reported, including 4(2.82%) cases in the treatment group and 2(1.41%) cases in the control group, which showed no statistically significant difference between the two groups. No serious suspected unexpected adverse reactions were reported, and no laboratory test results indicated serious clinically significant abnormalities. The results support the replacement of Os Draconis by Ostreae Concha in the original formula, and the efficacy and safety of the modified formula are consistent with those of the original formula.

Acute kidney injury (AKI) is a common clinically critical syndrome in hospitalized patients with high morbidity and mortality. At present, the mechanism of AKI has not been fully elucidated, and no therapeutic drugs exist. As known, glycolytic product lactate is a key metabolite in physiological and pathological processes. The kidney is an important gluconeogenic organ, where lactate is the primary substrate of renal gluconeogenesis in physiological conditions. During AKI, altered glycolysis and gluconeogenesis in kidneys significantly disturb the lactate metabolic balance, which exert impacts on the severity and prognosis of AKI. Additionally, lactate-derived posttranslational modification, namely lactylation, is novel to AKI as it could regulate gene transcription of metabolic enzymes involved in glycolysis or Warburg effect. Protein lactylation widely exists in human tissues and may severely affect non-histone functions. Moreover, the strategies of intervening lactate metabolic pathways are expected to bring a new dawn for the treatment of AKI. This review focused on renal lactate metabolism, especially in proximal renal tubules after AKI, and updated recent advances of lactylation modification, which may help to explore potential therapeutic targets against AKI.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) can result in fatigue and post-exertional malaise; however, whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection exacerbates lower urinary tract symptoms (LUTS) is unclear. This study investigated the association between prenatal SARS-CoV-2 infection and postpartum LUTS. METHODS: A multicenter, retrospective cohort study was conducted at two tertiary hospitals in China from November 1, 2022, to November 1, 2023. Participants were classified into infected and uninfected groups based on SARS-CoV-2 antigen results. LUTS prevalence and severity were assessed using self-reported symptoms and the Incontinence Impact Questionnaire-Short Form (IIQ-7). Pelvic floor muscle activity was measured using electromyography following the Glazer protocol. Group comparisons were performed to evaluate the association of SARS-CoV-2 infection with LUTS and electromyography parameters, with stratified analyses conducted using SPSS version 26.0. RESULTS: Among 3,652 participants (681 infected, 2,971 uninfected), no significant differences in LUTS prevalence or IIQ-7 scores were observed. However, SARS-CoV-2 infection was an independent factor influencing the electromyographic activity of the pelvic floor muscles (mean tonic contraction amplitudes), regardless of delivery mode ( P = 0.001). CONCLUSION Prenatal SARS-CoV-2 infection was not significantly associated with an increased risk of postpartum LUTS but independently altered pelvic floor muscle electromyographic activity, suggesting potential neuromuscular effects.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective To investigate the relationship between serum programmed cell death 4(PDCD4),platelet-derived growth factor-BB(PDGF-BB)levels and atherosclerotic cardiovascular disease(ASCVD)in patients with type 2 diabetes mellitus(T2DM).Methods A total of 238 T2DM patients admitted to 3201 Hospital from January 2022 to August 2024 were selected as the T2DM group,and 120 healthy volunteers who visited the hospital for physical examination during the same period were selected as the control group.T2DM patients were divided into ASCVD group(82 cases)and non-ASCVD group(156 cases)according to the presence or absence of ASCVD.The serum levels of PDCD4 and PDGF-BB were detected by enzyme-linked immunosorbent assay.Multivariate unconditional Logistic regression was used to analyze the relationship be-tween serum PDCD4 and PDGF-BB levels and ASCVD in T2DM patients.Receiver operating characteristic curve was used to analyze the predictive efficiency of serum PDCD4 and PDGF-BB levels for ASCVD in T2DM patients.Results Compared with the control group,the serum levels of PDCD4 and PDGF-BB were signifi-cantly increased in the T2DM group(P<0.05).The incidence of ASCVD in the 238 patients with T2DM was 34.45%(82/238).Compared with the non-ASCVD group,the ASCVD group had significantly higher serum levels of PDCD4 and PDGF-BB(P<0.05).Hypertension,hyperlipidemia,high glycosylated hemoglobin,high PDCD4 and high PDGF-BB were independent risk factors for ASCVD in T2DM patients(P<0.05).The area under the curve of serum PDCD4 and PDGF-BB levels combined to predict ASCVD in T2DM patients was 0.873,which was larger than 0.790 and 0.780 predicted by serum PDCD4 and PDGF-BB levels alone(P<0.05).Conclusion The serum levels of PDCD4 and PDGF-BB are increased in patients with T2DM,which are independent risk factors for ASCVD.The combination of PDCD4 and PDGF-BB has a high predictive efficiency for ASCVD in patients with T2DM.

Objective To report a case of tibial synovial sarcoma and review relevant literature to enhance understanding of this disease.Methods The clinical data of a patient with tibial synovial sarcoma treated at Kaifeng Central Hospital were retrospectively analyzed.A literature search was conducted in domestic and international databases,including China National Knowledge Infrastructure(CNKI),Wanfang Data,PubMed,Web of Science,and Embase,up to July 2024.Relevant literature was comprehensively reviewed to summarize the imaging and pathological characteristics,treatment,and prognosis of synovial sarcoma.Results A 29-year-old female patient was admitted with left lower extremity pain.X-ray examination revealed a proximal tibia space-occupying lesion suggestive of malignancy,and a mid-tibial space-occupying lesion considered benign.Contrast-enhanced computed tomography(CT)and plain magnetic resonance imaging(MRI)of the proximal tibial lesion also suggested malignancy.Ultrasound-guided biopsy of the proximal tibial tumor revealed a poorly differentiated malignant tumor.Immunohistochemistry results indicated monophasic synovial sarcoma,requiring genetic testing for definitive diagnosis.The patient underwent wide resection of the proximal left tibial malignancy with tumor-type artificial joint replacement,combined with curettage and bone cement filling for the left mid-tibial lesion under anesthesia.Postoperative pathology of space-occupying lesions in the proximal tibia confirmed monophasic synovial sarcoma,and fluorescence in situ hybridization(FISH)demonstrated a rupture of the synovial sarcoma translocation gene(SYT)(i.e.,SS18 positive).There was no recurrence or metastasis found in the patient during the reexamination 6 months after postoperative chemotherapy.As of July 2024,15 cases of genetically confirmed primary intraosseous synovial sarcoma have been reported internationally.Symptoms included pain and swelling,with a medical history of 1-2 years.The X-ray and CT findings showed osteolytic destruction with bone cortical discontinuity.In 13 cases,the intraosseous masses extended to the extraosseous area;in 2 cases,punctate calcifications were detected within the masses.Plain MRI scan showed iso-signal or hypo-signal on T1WI and hyper-signal,iso-signal,and hypo-signal on fat-suppressed T2WI,and enhanced MRI scan demonstrated heterogeneous enhancement.Pathological examination showed spindle-shaped cells under microscopy.Immunohistochemistry results showed positive epithelial membrane antigen(EMA),broad-spectrum cytokeratin(AE1/AE3),Ewing's sarcoma marker(CD99),and transducin-like enhancer of Split 1(TLE1).Twelve patients underwent surgical treatment;6 patients received adjuvant chemotherapy after surgery,of whom 4 developed local recurrence or distant metastasis at initial diagnosis,and 3 died during follow-up.Among the 6 patients who did not receive adjuvant chemotherapy,3 suffered from recurrence or distant metastasis.Conclusions Primary intraosseous synovial sarcoma is a rare malignant tumor with non-specific clinical manifestations.Imaging features typically include osteolytic destruction and intraosseous masses extending extraosseously,suggesting an intraosseous origin.Pathology and immunohistochemistry aid diagnosis,but definitive confirmation relies on further genetic testing.At present,the main treatment regimens for synovial sarcoma involve comprehensive therapies such as surgery and adjuvant chemotherapy,and the prognosis of patients is poor.

For the treatment of atrial fibrillation,Professor WU Wei innovatively put forward the theory of heart-blood-vessels trinity and the theory of stasis-toxin causing palpitation.It is believed that atrial fibrillation is caused by stasis and toxin,and affects the heart,blood and vessels.The core pathogenesis of atrial fibrillation is due to qi stagnation,blood stasis and toxin.The treatment for atrial fibrillation should be closely based on the pathogenesis,the therapeutic principles of treating from the perspective of stasis and together by removing toxin gradually is advocated.And the therapy of regulating qi,activating blood and removing stasis is also the way to remove toxin.The medication is based on the modified Taoren Honghua Decoction,which is mainly composed of Persicae Semen,Carthami Flos,Chuanxiong Rhizoma,Corydalis Rhizoma,Rehmanniae Radix,Paeoniae Radix Rubra,Salviae Miltiorrhizae Radix et Rhizoma,Jujubae Fructus,Puerariae Lobatae Radix,Nardostachyos Radix et Rhizoma,Ostreae Concha,Poria,and Polygonati Odorati Rhizoma.According to the characteristics of Lingnan climate and atrial fibrillation mostly being easy to affect the emotions,the pungent drugs in the prescription are usually removed,and the specific herbal pair of Puerariae Lobatae Radix-Nardostachyos Radix et Rhizoma is added to remove toxin according to the differentiation of disease.Moreover,for the treatment of atrial fibrillation,Professor WU Wei also adopts traditional Chinese medicine(TCM)external treatment such as foot bath,acupuncture and moxibustion,and physical-breathing exercise as well as health-care methods for comprehensive regulation,relieving the toxin and restoring the original qi.During the treatment atrial fibrillation,Professor WU Wei follows the principle of precise intervention and comprehensive regulation with Chinese medicine,so as to achieve the purpose of eliminating symptoms,restoring sinus rhythm and improving physical constitution.The thoughts of Professor WU Wei for the syndrome differentiation and treatment of atrial fibrillation will provide reference for the treatment of atrial fibrillation with TCM.

Objective To explore the correlation of traditional Chinese medicine(TCM)syndrome types with endoscopic features and pathological types of gastric polyps.Methods A total of 1 746 patients with gastric polyps admitted to the Department of Spleen and Stomach Diseases,Dongguan Hospital of Guangzhou University of Chinese Medicine were enrolled.The clinical data of the patients were collected,including gender,age,information obtained by four diagnostic methods of TCM,and pathological types and predilection sites of gastric polyps as well as their number and size.The distribution of TCM syndromes in the patients with gastric polyps and their correlation with endoscopic features and pathological types of the polyps were analyzed.Results(1)Of the 1 746 patients,1 107(63.40%)were female and 639(36.60%)were male,with the male to female ratio being 1∶1.73.The incidence of gastric polyps was positively correlated with the age(P＜0.01):the older the age,the higher the incidence rate.The middle-aged and elderly people were the predilection population for gastric polyps,and the patients aged over 40 years old accounted for 87.40%.(2)The TCM syndrome types of patients with gastric polyps were predominated by spleen-stomach qi deficiency syndrome(418 cases,23.94%),and then came cold-damp obstruction syndrome(394 cases,22.57%),damp-heat in the spleen and stomach syndrome(353 cases,20.22%),qi stagnation and phlegm obstruction syndrome(311 cases,17.81%)and phlegm blended with blood stasis syndrome(70 cases,15.46%).(3)There was a statistically significant difference in the distribution of TCM syndromes between the genders(P＜0.01):spleen-stomach qi deficiency syndrome,cold-damp obstruction syndrome,qi stagnation and phlegm obstruction syndrome and phlegm blended with blood stasis syndrome were more common in the female,while damp-heat in the spleen and stomach syndrome was more common in the male.The distribution of TCM syndromes varied in different age groups(P＜0.01):patients aged over 30 years old were more likely to suffer spleen-stomach qi deficiency syndrome,patients aged 30-39 and 40-49 years old were more likely to suffer damp-heat in the spleen and stomach syndrome,patients aged 50-59 years old were more likely to suffer qi stagnation and phlegm obstruction syndrome,and patients aged 60 years old or above were more likely to suffer cold-damp obstruction syndrome.(4)The pathological types of gastric polyps were predominated by fundus gland polyps(1 327 cases,76.00%),followed by hyperplastic polyps(266 cases,15.23%),inflammatory polyps(146 cases,8.36%),and adenomatous polyps(7 cases,0.40%).There was a statistically significant difference in the distribution of TCM syndromes among various pathological types(P＜0.01):fundus gland polyps were common in the patients with spleen-stomach qi deficiency syndrome,hyperplastic polyps were common in the patients with qi stagnation and phlegm obstruction syndrome,inflammatory polyps were common in the patients with cold-damp obstruction syndrome,and adenomatous polyps were common in the patients with phlegm blended with blood stasis syndrome.(5)Gastric polyps were characterized by multiple polyps(1 120 cases,64.15%),single polyp was rare(626 cases,35.85%).The distribution of TCM syndromes varied in the patients with different number of polyps(P＜0.05):patients with multiple polyps were predominated by spleen-stomach qi deficiency syndrome(25.45%),patients with single polyp were predominated by damp-heat in the spleen and stomach syndrome(24.28%).(6)Gastric polyps frequently appeared in the gastric body and gastric fundus,with the diameter being or less than 0.5 cm.And the differences of the distribution of TCM syndromes in the patients with various favored sites and polyp size were not statistically significant(P＞0.05).Conclusion TCM syndrome types of patients with gastric polyps are correlated with gender and age of the patients and with the pathological types and number of gastric polyps.The incidence is positively correlated with the age,and middle-aged and elderly people are the predilection population of gastric polyps.The female incidence is significantly higher than that of the male,and damp-heat in the spleen and stomach syndrome is more common in the male while the rest of syndrome types are more common in the female.The patients with gastric fundus gland polyps usually suffer spleen-stomach qi deficiency syndrome,patients with hyperplastic polyps usually suffer qi stagnation and phlegm obstruction syndrome,patients with inflammatory polyps usually suffer cold-damp obstruction syndrome,and patients with adenomatous polyps usually suffer phlegm blended with blood stasis syndrome.
