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: This study aims to investigate the associations between genetic variations of pyroptosis pathway related key genes and adverse events (AEs) of postoperative chemoradiotherapy (CRT) in patients with rectal cancer. Methods: DNA was extracted from the peripheral blood which was collected from 347 patients before CRT. Sequenom MassARRAY was used to detect the genotypes of 43 haplotype-tagging single nucleotide polymorphisms (htSNPs) in eight pyroptosis genes, including absent in melanoma 2 (AIM2), caspase-1 (CASP1), caspase-4(CASP4), caspase-5 (CASP5), caspase-11 (CASP11), gasdermin D (GSDMD), gasdermin E (GSDME) and NLR family pyrin domain containing 3 (NLRP3). The associations between 43 htSNPs and AEs were evaluated by the odd ratios (ORs) and 95% confidence intervals (CIs) by unconditional logistic regression models, adjusted for sex, age, clinical stage, tumor grade, Karnofsky performance status (KPS), surgical procedure, and tumor location. Results: Among the 347 patients with rectal cancer underwent concurrent CRT with capecitabine after surgery, a total of 101(29.1%) occurred grade ≥ 2 leukopenia. rs11226565 (OR=0.41, 95% CI: 0.21-0.79, P=0.008), rs579408(OR=1.54, 95% CI: 1.03-2.29, P=0.034) and rs543923 (OR=0.63, 95% CI: 0.41-0.98, P=0.040) were significantly associated with the occurrence of grade ≥ 2 leukopenia. One hundred and fifty-six (45.0%) had grade ≥ 2 diarrhea, two SNPs were significantly associated with the occurrence of grade ≥ diarrhea, including CASP11 rs10880868 (OR=0.55, 95% CI: 0.33-0.91, P=0.020) and GSDME rs2954558 (OR=1.52, 95% CI: 1.01-2.31, P=0.050). In addition, sixty-six cases (19.0%) developed grade ≥2 dermatitis, three SNPs that significantly associated with the risk of grade ≥2 dermatitis included GSDME rs2237314 (OR=0.36, 95% CI: 0.16-0.83, P=0.017), GSDME rs12540919 (OR=0.52, 95% CI: 0.27-0.99, P=0.045) and NLRP3 rs3806268 (OR=1.51, 95% CI: 1.03-2.22, P=0.037). There was no significant difference in the association between other genetic variations and AEs of rectal cancer patients (all P>0.05). Surgical procedure and tumor location had great impacts on the occurrence of grade ≥2 diarrhea and dermatitis (all P<0.01). Conclusion: The genetic variants of CASP4, CASP11, GSDME and NLRP3 are associated with the occurrence of AEs in patients with rectal cancer who received postoperative CRT, suggesting they may be potential genetic markers in predicting the grade of AEs to achieve individualized treatment of rectal cancer.

Objective To evaluate the risk of hearing loss of assembly workers in an automobile manufacturing factory. Methods An 8-hour equivalent sound level monitoring was carried out for assembly posts in an automobile factory. The risk of noise-induced hearing loss of assembly workers was measured using the method specified in ISO 1999:2013(E). The risk of noise-induced hearing loss was assessed in a graded manner according to the Guidelines for the Management of Occupational Disease Hazards from Noise. The results were statistically analyzed using Pearson correlation analysis. Results The average 8-hour equivalent sound level of the assembly work post in this automobile manufacturing factory was 89.5 dB (A). At 4000 Hz, the hearing loss N₅₀ (dB) of assembly workers reached the maximum. The longer the exposure time, the higher the risk of high-frequency standard hearing threshold shift. The risk of high-frequency standard hearing threshold shift was at a relatively high level at 30 years of work, while the risk of noise deafness reached a higher level after 40 years of work. Conclusion The 8-hour equivalent sound level (L_EX,8h) of assembly workers in the automobile factory exceeds the occupational exposure limit. With the increase of exposure years, the risk of high-frequency standard hearing threshold shift and noise deafness increases.

Objective:To evaluate the effect of oxygen supply via the transnasal self-made pharyngeal oxygen catheter on the safe apnea time in pediatric patients undergoing tonsil surgery. Methods:Sixty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients of either sex, aged 2-6 yr, weighing 10-20 kg, scheduled for elective tonsillectomy under general anesthesia, were divided into 2 groups ( n=30 each) using a random number table method: transnasal self-made pharyngeal oxygen catheter for oxygen supply group (group NO) and control group (group C). Anesthesia was induced with intravenous midazolam, propofol, fentanyl and cis-atracurium, and then ventilation was performed with a mask, and the mask was removed when the exhaled oxygen concentration (C ETO 2) reached more than 90%.In group NO, the self-made oxygen catheter was implanted into the oropharynx through the nose, and the 100% oxygen at 10 L/min was aspirated through the humidification bottle until the intubation was successful.In group C, the transnasal self-made oxygen catheter was not implanted, and the rest of the protocol was similar to those previously described in group NO.The visual laryngoscope was implanted to simulate difficult airways.When SpO 2 ≤ 95% or the safe apnoea time reached 600 s, the observation of apnea was stopped, and mechanical ventilation was started after successful rapid endotracheal intubation.The safe apnea time (from removing the mask until SpO 2 decreased to 95%), value of C ETO 2 at the end of mask ventilation, and the minimum value of SpO 2 after stopping mask ventilation were recorded.Heat rate and mean arterial pressure were observed and recorded on admission to the operating room, immediately after onset of apnea and immediately after successful endotracheal intubation.The SpO 2, P ETCO 2 and cross-sectional area of gastric antrum were also recorded immediately after onset of apnea and immediately after successful endotracheal intubation, and the rate of increase in P ETCO 2 was calculated.The nasal bleeding, nasal dryness, postoperative pharyngeal discomfort and other adverse reactions were recorded when the self-made pharyngeal oxygen catheter was placed. Results:Compared with group C, the safe apnea time was significantly prolonged, the rate of increase in P ETCO 2 was decreased, the minimum value of SpO 2 after stopping mask ventilation was increased, and the heat rate, mean arterial pressure, SpO 2 and P ETCO 2 were increased immediately after successful intubation ( P<0.05), no significant change was found in C ETO 2 after stopping mask ventilation and cross-sectional area of gastric antrum at each time point in group NO ( P>0.05). No adverse reactions such as nasal bleeding, nasal dryness and postoperative pharyngeal discomfort were found when the self-made pharyngeal oxygen catheter was inserted in group NO. Conclusions:The oxygen supply with the transnasal self-made pharyngeal oxygen catheter technique can prolong the safe apnea time in the pediatric patients undergoing tonsil surgery.

To identify Glycyrrhizae Radix et Rhizoma from different geographical origins, spectrum and image features were extracted from visible and near-infrared(VNIR, 435-1 042 nm) and short-wave infrared(SWIR, 898-1 751 nm) ranges based on hyperspectral imaging technology. The spectral features of Glycyrrhizae Radix et Rhizoma samples were extracted from hyperspectral data and denoised by a variety of pre-processing methods. The classification models were established by using Partial Least Squares Discriminate Analysis(PLS-DA), Support Vector Classification(SVC) and Random Forest(RF). Meanwhile, Gray-Level Co-occurrence matrix(GLCM) was employed to extract textural variables. The spectrum and image data were implemented from three dimensions, including VNIR and SWIR fusion, spectrum and image fusion, and comprehensive data fusion. The results indicated that the spectrum in SWIR range performed better classification accuracy than VNIR range. Compared with other four pre-processing methods, the second derivative method based on Savitzky-Golay(SG) smoothing exhibited the best performance, and the classification accuracy of PLS-DA and SVC models were 93.40% and 94.11%, separately. In addition, the PLS-DA model was superior to SVC and RF models in terms of classification accuracy and model generalization capability, which were evaluated by confusion matrix and receiver operating characteristic curve(ROC). Comprehensive data fusion on SPA bands achieved a classification accuracy of 94.82% with only 28 bands. As a result, this approach not only greatly improved the classification efficiency but also maintained its accuracy. The hyperspectral imaging system, a non-invasively, intuitively and quickly identify technology, could effectively distinguish Glycyrrhizae Radix et Rhizoma samples from different origins.

To systematically evaluate the clinical efficacy and safety of Lianhua Qingwen in the treatment of adult pneumonia. The randomized controlled trial of Lianhua Qingwen combined with conventional Western medicine in the treatment of pneumonia were retrieved from PubMed, EMbase, Wanfang database, VIP database, and CNKI from the establishment of database to March 2020. Two researchers independently conducted literature screening and data extraction, and the third researcher was in charge of arbitration in case of any disagreement. Outcome indicators included total clinical effective rate, symptom improvement time, and incidence of adverse events. R 3.6.1 was used for Meta-analysis, and RevMan 5.3 was used for quality evaluation. Twenty-two studies were included, with a total of 2 007 patients, including 1 017 patients in the experimental group and 990 patients in the control group. The results showed that the total clinical effective rate of the experimental group was higher than that of the control group(RR=1.11, 95%CI[1.08, 1.15], P<0.001), and the antifebrile time(MD=-1.81, 95%CI[-2.42,-1.21], P<0.001), cough duration(MD=-2.32, 95%CI[-2.89,-1.76], P<0.001), rale duration(MD=-2.19, 95%CI[-2.74,-1.63], P<0.001), imaging recovery time(MD=-2.17, 95%CI[-2.76,-1.58], P<0.001) and post-treatment CRP(MD=-4.07, 95%CI[-6.39,-1.75], P<0.001] were all significantly lower than those of the control group. However, it did not proved that the experimental group was safer than the control group(RR=0.84, 95%CI[0.57, 1.24], P=0.382). The results confirmed that Lianhua Qingwen combined with conventional Western medicine in the treatment of pneumonia could improve the clinical treatment efficiency, shorten the time of fever, cough, rale disappearance and imaging recovery, improve CRP index and accelerate the recovery of pneumonia patients. However, the literatures included in this study had a low quality, and the conclusions still need to be further confirmed by more high-quality, multi-center, rigorously designed randomized controlled trial.

In order to establish a rapid and non-destructive evaluation method for the identification of Armeniacae Semen Amarum and Persicae Semen from different origins, the spectral information of Armeniacae Semen Amarum and Persicae Semen in the range of 898-1 751 nm was collected based on hyperspectral imaging technology. Armeniacae Semen Amarum and Persicae Semen from different origins were collected as research objects, and a total of 720 Armeniacae Semen Amarum samples and 600 Persicae Semen samples were used for authenticity discrimination. The region of interest(ROI) and the average reflection spectrum in the ROI were obtained, followed by comparing five pre-processing methods. Then, partial least squares discriminant analysis(PLS-DA), support vector machine(SVM), and random forest(RF) method were established for classification models, which were evaluated by the confusion matrix of prediction results and receiver operating characteristic curve(ROC). The results showed that in the three sample sets, the se-cond derivative pre-processing method and PLS-DA were the best model combinations. The classification accuracy of the test set under the 5-fold cross-va-lidation was 93.27%, 96.19%, and 100.0%, respectively. It was consistent with the confusion matrix of the predicted results. The area under the ROC curve obtained the highest values of 0.992 3, 0.999 6, and 1.000, respectively. The study revealed that the near-infrared hyperspectral imaging technology could accurately identify the medicinal materials of Armeniacae Semen Amarum and Persicae Semen from different origins and distinguish the authentication of these two varieties.

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.
