Objective: To study the antibacterial activity in vitro of Xiyanping injection combined with cefoxitin, cefuroxime, ceftriaxone, cefmenoxime, amikacin, levofloxacin and meropenem against staphylococcus aureus, escherichia coli, klebsiella pneumoniae, pseudomonas aeruginosa and acinetobacter bauman.Methods: Minimum inhibitory concentration (MIC) of the 7 kinds of antimicrobial agents used individually or combined with Xiyanping injection on germs were determined respectively on 96 plates by using the agar dilution method and the checkerboard method.Fractional inhibitory concentration index (FICI) was calculated to evaluate the antibacterial activity of Xiyanping injection combined with the 7 kinds of antimicrobial agents in vitro.Results: MIC of Xiyanping injection combined with cefoxitin was the same as that of cefoxitin used individually on escherichia coli.MIC of levofloxacin combined with Xiyanping injection showed no difference with that of levofloxacin used individually on klebsiella pneumoniae.Besides, Xiyanping injection could increase the MIC of the other antimicrobial agents on germs.Conclusion: Xiyanping injection combined with antimicrobial agents on staphylococcus aureus, escherichia coli, klebsiella pneumoniae shows antagonistic and irrelevant relationship.

Objective:To study the genetic profiles and clinical characteristics of neonatal-onset genetic epilepsy.Methods:From July 2016 to May 2021, patients with neonatal-onset genetic epilepsy admitted to our hospital and received second-generation genetic sequencing were enrolled in this study. According to the types of genetic variations, the patients were assigned into ion channel group and non-ion channel group. Clinical characteristics, treatments and prognosis of the two groups were compared.Results:A total of 36 patients with identified genetic variations were enrolled, involving 15 epilepsy-related genes. KCNQ2, SCN2A and STXBP1 were the most common pathogenic genes. 20 cases (55.6%) were in the ion channel group and 16 cases (44.4%) in the non-ion channel group. No significant differences existed in their general status, seizure types, EEG characteristics, treatments and outcomes between the two groups ( P>0.05). Among all 36 cases, the age of onset ranged from 10 min to 24 d after birth and 28 cases (78.8%) developed epilepsy within 1 week after birth. Developmental and epileptic encephalopathies were diagnosed in 20 patients. 7 patients were diagnosed with self-limited neonatal epilepsy, 2 were pyridoxine dependence, 2 were Zellweger syndrome and 1 case of self-limited familial neonatal-infantile epilepsy, Turner type mental retardation with epilepsy, PURA syndrome, Rett syndrome and 22q11.2 deletion syndrome, each. The patients received antiepileptic drugs including phenobarbital, levetiracetam, oxcarbazepine, topiramate, valproic acid, benzodiazepines (nizepam/clonazepam /clobazam/midazolam), lacosamide and lamotrigine. 5 patients died after giving up treatment. 31 patients were followed up for 6 to 50 months. 22 cases (71.0%) were controlled at 1- to 35-month-old including 21 cases (56.7%) with developmental delay. 6 cases (19.4%) had ineffective seizure control and 3 cases (9.7%) showed reduced seizures, all with varying degrees of developmental delay. Conclusions:Neonatal-onset epilepsy is correlated with multiple genes. KCNQ2, SCN2A, STXBP1 are the common pathogenic genes with multiple variants of KCNQ2 gene. Most patients have seizures within 1 week after birth. More than half of patients have ion channel related gene variations. Sodium channel blockers have certain effects as treatment.

ObjectiveTo investigate the impact of yang deficiency syndrome on the progression to end-point events of diabetic kidney disease (DKD). MethodsA retrospective study among patients with stage Ⅳ DKD admitted to Dongzhimen Hospital of Beijing University of Chinese Medicine from September 1st, 2016 to September 30th, 2021 was conducted. Data on the patients' general information, clinical indicators including duration of diabetes, duration of proteinuria, history of smoking and drinking, hemoglobin (HGB), fasting blood glucose (FBG), albumin (ALB), serum creatinine (Scr), urea nitrogen (BUN), uric acid (UA), cholesterol (TC) , triglycerides (TG), low-density lipoprotein (LDL), 24-hour urine protein quantification (24h-UTP) and estimated glomerular filtration rate (eGFR), and TCM syndromes including symptoms, tongue and pulse, and syndrome scores were collected. The patients were divided into exposure group (yang-deficiency group) and non-exposure group (non-yang-deficiency group). The general information, clinical indicators and incidence rates of end-point events were compared, and the impact of yang deficiency syndrome on the end-point events of stage Ⅳ DKD was analyzed. Survival analysis was performed using Kaplan-Meier method, and multivariate Cox proportional risk models were used to identify independent predictors of end-point events. ResultsA total of 160 patients with stage Ⅳ DKD were included in the study, including 43 cases of yang deficiency syndrome and 117 cases of non-yang deficiency syndrome. Compared to those in the non-yang deficiency group, the waist circumference, BUN and the incidence of end-point events in the yang deficiency group were significantly higher (P<0.05 or P<0.01). Spearman correlation analysis showed that yang deficiency syndrome was positively correlated with incidence of end-point events of stage Ⅳ DKD (r = 0.167, P = 0.035). Furthermore, 24h-UTP and BUN levels were also positively correlated with end-point events in stage Ⅳ DKD patients (P<0.01), while ALB and HGB levels were negatively correlated (P<0.01). Kaplan-Meier survival curves showed that yang deficiency syndrome was associated with an increased risk of end-point events (Log Rank P = 0.011). Moreover, 24h-UTP levels ≥3500 mg, BUN level ≥8 mmol/L, ALB level <30 g and HGB level <11 g were all associated with the increase of the risk of end-point events (P<0.05 or P<0.01). Multivariate Cox regression analysis showed that yang deficiency syndrome was an independent risk factor for patients with stage Ⅳ DKD to progress into end-point events (HR = 2.36, 1.32 to 4.21; P = 0.004), as well as 24h-UTP ≥ 3500 mg, BUN ≥ 8 mmol/L, HGB<11 g and ALB<30 g (P<0.05 or P<0.01). ConclusionsFor stage Ⅳ DKD, patients with yang deficiency syndrome are more likely to have end-point events, which is an independent risk factor for the progression into end-point events.
