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 (LEX,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.

Objective:
The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.
Methods:
The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.
Results:
A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).
Conclusion
An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

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.
