Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

BACKGROUND: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m MAIN OUTCOME MEASURES: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

OBJECTIVE: To evaluate the efficacy and safety of Yangyin Yiqi Huoxue Granule (, YYHG) in the treatment of ischemic stroke (IS) patients with qi-yin deficiency and blood stasis syndrome (QYDBSS), and to explore its effective dosage. METHODS: The total of 288 patients were randomly assigned to the YYHG high-dose, YYHG low-dose, positive control (administered Xiaoshuantong Granule, XSTG, ), or placebo control (administered inert granule) groups (72 cases per group) by software-drived competitive block randomization. The trial was conducted for a 28-day period, with a 180-day follow-up period. The primary outcome was the comprehensive curative evaluation, and secondary outcomes were the National Institute of Health Stroke Scale (NIHSS) score, Barthel activities of daily living (ADL) index score, the quality of life index (QLI) score, and the Chinese medicine syndrome (CMS) score. All analyses were done on an intention-to-treat basis. The clinical safety was also assessed. RESULTS: The total of 288 participants were recruited between June 1, 2008 and September 30, 2009, and 287 patients received intervention; the treatment groups were well balanced at baseline. The comprehensive cure rates of YYHG high-dose, low-dose, positive and placebo control groups were 63.38%, 31.94%, 36.11% and 6.14%, respectively; there was a statistical difference between the two groups (P<0.01), while the high-dose YYHG treatment group was significantly higher than the other 3 groups (P<0.01). The improvement of NIHSS, ADL, QLI and CMS scores of the YYHG high-dose and low-dose groups was significantly better than that of the positive control group and the placebo control group (P<0.05). In terms of improving the classification of the NIHSS scale and the assessment of the ADL scale, the YYHG high-dose group was significantly better than the other three groups (P<0.05), and the YYHG low-dose group was better than the placebo control group (P<0.01). At the same time, except for the QLI score, the high-dose group was better than the low-dose group (P<0.05). In terms of safety, adverse reactions after YYHG treatment were generally mild (3.78%), and no serious adverse reactions have been reported. CONCLUSION YYHG is safe and effective in the treatment of IS patients with QYDBSS.

OBJECTIVE: To evaluate whether the efficacy of Getong Tongluo Capsule (, GTC, consisted of total flavone of Radix Puerariae) on improving patients' quality of life and lowering blood pressure are superior to the extract of Ginkgo biloba (EGB) for patients with convalescent-phase ischemic stroke and primary hypertension. METHODS: This randomized, positive-drug- and placebo-controlled, double-blind trial was conducted from September 2015 to October 2017. Totally 477 eligible patients from 18 hospitals in China were randomly assigned in a 2:1:1 ratio to the following interventions, twice a day for 12 weeks: (1) GTC 250 mg plus EGB-matching placebo 40 mg (237 cases, GTC group), (2) EGB 40 mg plus GTC-matching placebo 250 mg (120 cases, EGB group) or (3) GTC-matching placebo 250 mg plus EGB-matching placebo 40 mg (120 cases, placebo group). Moreover, all patients were orally administered aspirin enteric-coated tablets 100 mg, once a day for 12 weeks. The primary outcome was the Barthel Index (BI). The secondary outcomes included the control rate of blood pressure and National Institutes of Health Stroke Scale (NIHSS) scores. The incidence and severity of adverse events (AEs) were calculated and assessed. RESULTS: The BI relative independence rates, the clinical recovery rates of NIHSS, and the total effective rates of NIHSS in the GTC and EGB groups were significantly higher than the placebo group at 12 weeks after treatment (P<0.05), and no statistical significance was found between the GTC and EGB groups (P>0.05). The control rate of blood pressure in the GTC group was significantly higher than the EGB and placebo groups at 12, 18 and 24 weeks after treatment (P<0.01). There were no statistically significant differences in the incidences of AEs, adverse drug reactions, or serious AEs among the 3 groups (P>0.05). CONCLUSION GTC exhibited significant efficacy in improving patients' quality of life as well as neurological function and controlling hypertension. (Registration No. ChiCTR1800016667).

BACKGROUND: Catheter ablation is effective in restoring sinus rhythm and left atrial appendage closure (LAAC) is increasingly used for stroke prevention in patients with atrial fibrillation (AF). We aimed to observe the feasibility and safety of performing AF ablation and LAAC in a single (one-stop) procedure. METHODS: Consecutive AF patients who underwent the combined procedure of AF ablation and LAAC with WATCHMAN device between March 2017 and September 2018 were prospectively enrolled. Baseline and intra-procedural parameters were evaluated. Three-month and subsequent 1-year follow-up were performed in all and earlier-enrolled subjects, respectively. RESULTS: A total of 178 AF patients (94 males, 68.9 ± 8.1 years) underwent the one-stop procedure with CHA2DS2-VASc score 3.3 ± 1.5 and HAS-BLED score 1.6 ± 1.0, respectively. Pulmonary vein isolation was achieved in all patients while additional linear ablation was applied if the operator deemed necessary, yielding immediate ablation success rate of 98.9% (176/178). In the subsequent LAAC, satisfactory seal (residual leak <5 mm) was achieved in all patients. One stroke and four cardiac perforations occurred peri-operatively. At 3-month follow-up, sinus rhythm and satisfactory seal were maintained in 153/178 (86.0%) and 178/178 (100%) patients, respectively. One stroke and one delayed cardiac tamponade occurred, while no device-related thrombus or device migration was observed. During the 1-year follow-up for the earlier enrolled subjects, 52/72 (72.2%) of the patients maintained sinus rhythm. There was no stroke or systemic embolism observed. CONCLUSION Combining catheter ablation and LAAC in a single procedure can be successfully and safely performed in non-valvular AF patients of Chinese population.

Objective:To study the efficacy of integrative medicine on congenital muscular torticollis. Methods:From October, 2017 to September, 2019, 80 children with congenital muscular torticollis were divided into group 1 (n = 40) and group 2 (n = 40) according to different treatment schemes. Group 1 received comprehensive physiotherapy, including passive stretching, head control training, posture correction and family rehabilitation. Group 2 received Tuina in addition. Before and six months after treatment, the root mean square (RMS) of surface electromyography of bilateral sternocleidomastoid muscles in supine neutral position, neck rotation and stretch, and the range of motion of passive neck rotation and lateral flexion, and the angle of head deviation from the midline to the affected side were compared. Results:Before treatment, the RMS of sternocleidomastoid muscle in each position was lower in the affected side than in the healthy side (P < 0.01), and the range of motion of neck when lateral flexion to the healthy side and rotation to the affected side was less than that of the other side (P < 0.01) in both groups; however, no significant difference was found between two groups (P > 0.05). After treatment, the RMS of EMG of sternocleidomastoid muscle in each position, and the range of motion of neck when lateral flexion to the healthy side and rotation to the affected side improved (|t| > 3.290, P < 0.01) in both groups, and were better in group 2 than in group 1 (t > 2.401, P < 0.05); the angle of head deviation from the midline to the affected side significantly decreaed (t > 15.075, P < 0.001) in both groups, and was significantly less in group 2 than in group 1 (t = -4.971, P < 0.001). Conclusion:Integrative medicine is effective on infant with congenital muscular torticollis, which is superior to comprehensive physiotherapy only.

Objective: We aimed to explore the feasibility and perioperative safety of performing catheter ablation and left atrial appendage closure (LAAC) in a single (one-stop) session in patients with atrial fibrillation (AF). Methods: This study is an observational study. Consecutive AF patients who underwent the combined procedure of catheter ablation and LAAC with Watchman device of Xinhua Hospital in Shanghai between March 2017 and May 2019 were prospectively enrolled. Baseline, intra-and peri-procedural parameters were evaluated. Results: A total of 358 AF patients (189 males, (69.0±8.0) years) underwent the one-stop procedure. The CHA₂DS₂-VASc score was 3.2±1.5 and HAS-BLED score was 2.4±1.1, respectively in this patient cohort. Pulmonary vein isolation was achieved in all patients, while additional linear ablation was applied in 180 (50.3%) patients, yielding immediate success rate of 99.7%. Successful Watchman implantation was achieved in all patients. The perioperative serious adverse event occurred in 14 cases (3.9%). including 6 pericardial effusions (1.7%), 1 stroke (0.3%) and 5 vascular complications (1.4%), yielding procedure-related complication rate of 3.4%. In addition, 2 (0.6%) new-onset heart failures occurred postoperatively. There was no major bleeding or death during the perioperative period. Conclusions: Combined catheter ablation and LAAC can be successfully and safely performed in AF patients with high stroke risk. Follow-up data are needed to evaluate the outcome of this one-stop procedure.

BACKGROUND: The current upper-frequency cutoff of 150 Hz sometimes causes loss of pacemaker spike and misdiagnosis. We hypothesized that low-pass filter (LPF) other than 150 Hz could improve the detection of pacemaker spike. This study aimed to examine the effect of different LPF on pacemaker spike detection in remote and bedside electrocardiogram (ECG). METHODS: Patients with permanent pacemaker implantation were included during routine follow-up. Standard 12-lead ECGs at 6 different upper-frequency cutoff (40, 100, 150, 200, 300, and 400 Hz) were collected. All ECGs were then transmitted to the remote clinic center. Ventricular and atrial pacing were analyzed by 2 independent medical practitioners. RESULTS: A total of 88 patients' ECGs were analyzed (mean age 73.8 ± 10.2 years and 85 with dual-chamber pacemakers). About 75.3% (64/85) of patients were diagnosed as atrial pacing by pacemaker programming. Among 6 different upper-frequency cutoff, the 300 Hz turned out to perform best in detecting atrial-paced spike (area under the curve [AUC] = 0.73, 95% confidence interval [CI]: 0.61-0.84 vs. 0.56, 95% CI: 0.61-0.84 at 150 Hz; P = 0.002) on bedside ECGs. Using programming as the golden standard, the 300 Hz LPF has a sensitivity of 59.4%, specificity of 85.7%, positive predictive value of 92.7% and negative predictive value of 40.9% on bedside ECGs. As for the ventricular pacing, the 300 Hz LPF also had a higher accuracy (AUC = 0.93; 95% CI = 0.84-1.00) than that at 150 Hz (AUC = 0.86; 95% CI: 0.77-0.94; P < 0.001) in detecting ventricular-paced spike on bedside ECGs. The results of remote ECGs were similar with bedside ECGs. CONCLUSIONS A filter of 300 Hz cutoff may be recommended for ECG spike detection. With the recommended parameter, remote ECG can perform as well as bedside ECG.

Objective: To detect the expression of non-coding RNA snord105b in gastric cancer (GC) tissues, sera and cell lines, and its correlation with clinicopathological characteristics of patients with GC as well as its effect on the proliferation of GC cells. Methods: One hundred and twenty pairs of GC tissues and corresponding para-cancerous tissues from patients, who underwent surgery at Department of Surgery, the Fourth Hospital of Hebei Medical University between 2016 and 2017, were collected for this study. The presurgical sera samples from GC patients (n=50) and peripheral venous blood samples from healthy donors (n=30), as well as five gastric cancer cell lines (SGC-7901, AGS, MGC-803, BGC-823, HGC-27) and gastric mucosa normal epithelial GES-1 cells were also obtained. qPCR assay was adopted to detect the expression of snord105b in GC tissues, sera and cell lines. The correlation between snord105b and patients’clinicopathological features was investigated. MTS assay was adopted to detect the effect of snord105b silence or over-expressionon in vitro proliferation of four GC cells. Results: qPCR assay demonstrated that the expression of snord105b in GC tissues, sera and cell lines were significantly higher than that of para-cancerous tissues, sera from healthy donors and GES-1 cells (all P< 0.05). Expression level of snord105b was obviously associated with age,tumor size, differentiation and TNM stages of patients (all P<0.05). MTS assay demonstrated that knockdown of snord105b could suppress the proliferation of GC cells (P< 0.05), while forced-expression of snord105b could promote the proliferation of GC cells (P< 0.05). Conclusion: non-coding RNA snord105b aberrantly expressed in GC tissues, sera, and cells, and its expression was obviously correlated with patients’age, tumor size, differentiation and TNM stages. Snord105b could significantly promote the proliferation of GC cells, which may be used as a potential clinical biomaker for early diagnosis and prognosis of GC.

Objective To evaluate the value of interstitial magnetic resonance lymphography (MRL) to identify the sentinel lymph node (SLN) of breast cancer.Methods Totally 58 patients with invasive breast cancer were consecutive collected.15 mL of Gd-DTPA and 2 mL of mepivacain hydrochloride 2% were mixed and 0.5 mL of them was injected into the outside of the subareolar breast tissue.MRI was performed with Siemens 3.0 T Magnetom Trio MRI instrument using volumetric interpolated breath-hold examination sequence.Axillary lymph flow was tracked on maximum intensity projection (MIP) and sentinel lymph nodes were identified by interstitial MRL as M-SLN.All M-SLN were marked by a method of surface capsule localization.During surgery, methylene blue was used as tracer and SLNs stained by it were detected and excised by following the blue lymphatic vessels,these were designated as D-SLN.The numbers of SLNs detected by interstitial MRL and stained by methylene blue during operation were compared by paired samples rank-sum test and the correlation was analyzed by Spearman rank correlation test.Assessing the sensitivity, specificity and accuracy of interstitial MRL for diagnosing M-SLN.Results A total of 75 M-SLNs (average 1.60 ± 0.52) were identified by interstitial MRL.During operation, all M-SLNs were easily resected under the guidance of skin marker.91 D-SLNs (average 1.94±0.63) were stained by methylene blue, which was significant more than those of the M-SLNs.There was a strong correlation (Spearman's rank correlation coefficient 0.69,P<0.001) between the SLNs identified by these two methods.Interstitial MRL in diagnosing D-SLN metastasis of breast cancer had a sensitivity of 95.8%,specificity of 88.9%,and accuracy of 93.3%.Conclusion Interstitial MRL can accurately identify the axillary sentinel lymph node and guide the biopsy.It may have great clinical value in the future.
