BACKGROUND: Monoclonal antibody therapy for Covid-19 springs up all over the world and get some efficiency. This research aims to explore the treating effect of BRII-196(Ambavirumab) plus BRII-198(Lomisivir) on Covid-19. METHODS: In this retrospective cohort research, patients received standard care or plus BRII-196 /BRII-198 monoclonal antibodies. General comparison of clinical indexes and prognosis between Antibody Group and Control Group was made. Further, according to the antibody using time and patients' condition, subgroups included Early antibody group, Late antibody group, Mild Antibody Group, Mild Control Group, Severe Antibody Group and Severe Control Group. RESULTS: Length of stay(LOS) and interval of Covid-19 nucleic acid from positive to negative of Antibody Group were 12.0(IQR 9.0-15.0) and 14.0(IQR 10.0-16.0) days, less than those(13.0 (IQR 11.0-18.0) and 15.0 (IQR 12.8-17.0) days) of Control Group(p = 0.004, p = 0.004). LOS(median 10days) of Early Antibody Group was the shortest, significantly shorter than that of Control Group (median 13days)(p < 0.001). Interval(median 12days) of Covid-19 nucleic acid from positive to negative of Early Antibody Group also was significantly shorter than that of Control Group(median 15days) and Late Antibody Group(median 14days)(p = 0.001, p = 0.042). LOS(median 12days) and interval(median 13days) of Covid-19 nucleic acid from positive to negative of Mild Antibody Group was shorter than that of Mild Control Group(median 13days; median 14.5days)(p = 0.018, p = 0.033). CONCLUSION: The neutralizing antibody therapy, BRII-196 plus BRII-198 could shorten LOS and interval of Covid-19 nucleic acid from positive to negative. However, it didn't show efficacy for improving clinical outcomes among severe or critical cases.

BACKGROUND: Volume resuscitation is often required in critically ill patients. However, we have no clear consensus on the choice between crystalloid solution and colloidal solution. This study aimed to explore the effect of albumin administration in massive fluid resuscitation. METHODS: This was a retrospective cohort study based on the Medical Information Mart for Intensive Care IV (MIMIC-IV) database (2008 and 2019). The prognosis of patients receiving albumin in combination with crystalloids and those receiving crystalloids alone was compared to assess the benefits of albumin in fluid resuscitation. RESULTS: 4426 patients received crystalloids alone (crystalloids group), 692 patients received albumin in combination with crystalloids within the first 24 h of initiation of crystalloids (early albumin combination group), and 382 patients received albumin after the first 24 h (late albumin combination group). Patients in early albumin combination group were more severe than those in Crystalloids group. Nevertheless, we found no statistically significant difference in mortality between the two groups. Multivariate logistic regression analysis using the propensity-score matched cohort showed that the 28-day and 60-day mortality in the early albumin combination group were lower than those in the crystalloids group (odds ratio: 0.64 [95% CI 0.50-0.82; P < 0.001] and 0.71 [95% CI 0.56-0.90; P = 0.004], respectively. Patients in early albumin combination group lived, on average, 1.16 days (95% CI 0.33-2.00; P < 0.01) and 3.3 days (95% CI 1.15-5.44; P < 0.01) longer than the crystalloids group during 28-day follow-up and 60-day follow-up. CONCLUSION: Administration of albumin within 24 h after the initiation of crystalloids was associated with a lower mortality and a longer restricted mean survival time during 28-day follow-up and 60-day follow-up compared with crystalloid infusion alone. However, administration of albumin 24 h after the initiation of crystalloids was not associated with better prognosis compared to crystalloid infusion alone.

Synthesis of highly stable two-dimensional single-layer assemblies (SLAs) is a key challenge in supramolecular science, especially those with long-range molecular order and well-defined morphology. Here, thin (thickness <2â nm) triangular AuI -thiolate SLAs with high thermo-, solvato- and mechano- stability have been synthesized via a double-ligand co-assembly strategy. Furthermore, the SLAs show assembly-level elastic and anisotropic deformation responses to external stimuli as a result of the long-range anisotropic molecular packing, which provides SLAs with new application potentials in bio-mimic nanomechanics.
ObjectiveTo analyze the distribution of traditional Chinese medicine （TCM） patterns as well as factors related to acute exacerbation in group E of chronic obstructive pulmonary disease （COPD）. MethodsThe general data of 161 COPD patients， including gender， age， body mass index （BMI）， disease course， smoking history， and past history， were collected. In terms of the four examinations of TCM， the differentiated patterns included phlegm-heat obstructing the lung， turbid phlegm obstructing the lung， phlegm stasis obstructing the lung， lung-spleen qi deficiency， and lung-kidney deficiency. The modified British Medical Research Council （mMRC） scale and COPD assessment test （CAT）， the pulmonary function indicators including forced expiratory volume in the first second （FEV1） and ratio of forced expiratory volume to forced vital capacity at second 1 （FEV1/FVC）， GOLD grade， and the patient's acute exacerbations in the previous year were recorded. Multivariate regression analysis was performed using logistic regression model to determine the relevant factors of patients in COPD group E. The distribution of acute exacerbations in different TCM symptom patients in group E was analyzed. ResultsThere were 80 patients （49.69%） in group E and 81 patients （50.31%） in non-group E. In group E， 23 （28.75%） patients had a history of two acute exacerbations， while 35 （43.75%） had three acute exacerbations， and 22 （27.5%） had more than three acute exacerbations. There were 13 （16.25%） cases of phlegm-heat obstructing the lung pattern， 6 （7.5%） cases of turbid phlegm obstructing the lung pattern， 8 （10%） cases of phlegm stasis obstructing the lung pattern， 22 cases （27.5%） of lung-spleen qi deficiency pattern， and 31 （38.75%） cases of lung-kidney deficiency pattern. There were significant differences in smoking history， disease course， TCM pattern， TCM syndrome score， mMRC score， and CAT score between groups （P＜0.05）. A total of 107 of the 161 patients completed pulmonary function tests， and the differences in FEV1， FEV1/FVC and GOLD grades between groups were statistically significant （P＜0.05）. Multivariate regression analysis showed that TCM pattern， TCM syndrome score and CAT score were statistically significant factors for COPD patients in group E （P＜0.05）. There were statistically significant differences in the number of acute exacerbations in different TCM patterns in group E （P＜0.05）. The patients with two acute exacerbations in the past year were mainly phlegm-heat obstructing the lung and lung-spleen qi deficiency patterns， while the three acute exacerbations were mainly seen in lung-spleen qi deficiency and lung-kidney deficiency patterns， and more than three exacerbations were more common with lung -kidney deficiency pattern. ConclusionsPatients in COPD group E were mainly the lung-spleen qi deficiency and lung-kidney deficiency patterns. Deficiency of healthy qi is the main reason for the increase in the number of acute exacerbations， and TCM patterns and CAT score were the main related factors.
ObjectiveTo observe the effect of Chonglian oral liquid on inflammatory and immune markers as well as the clinical outcomes of patients with mild-to-moderate corona virus disease 2019（COVID-19） and comprehensively evaluate its efficacy and safety. MethodA clinical randomized controlled trial （RCT） was conducted， involving 120 confirmed cases of mild-to-moderate COVID-19. The patients were randomly divided into two groups， with 55 cases in the observation group and 56 cases in the control group. According to the updated diagnosis and treatment protocol， the control group received standard western medical treatment， while the observation group received Chonglian oral liquid in addition to standard western medical treatment. Both groups were treated continuously for 10 days. The traditional Chinese medicine （TCM） syndrome scores， syndrome efficacy， fever abatement time， nucleic acid negative conversion time， inflammatory and immune markers， improvement in imaging findings， clinical outcomes， and occurrence of adverse events were compared between the two groups. ResultBoth groups showed a significant decrease in TCM syndrome scores after treatment （P<0.01）. Compared with the control group after treatment， the observation group exhibited a more significant improvement in cough， dry throat， sore throat， fatigue， and muscle pain （P<0.05）. The total effective rate in the observation group was 100% （55/55）， significantly higher than 98.21% （55/56） in the control group （Z=3.707， P<0.01）. The observation group also showed a significantly shorter duration of fever abatement and nucleic acid negative conversion compared with the control group after treatment （P<0.05）. Both groups had a significant increase in lymphocyte count （LYM）， lymphocyte percentage （LYM%）， mature T lymphocytes （CD3+）， and helper/inducer T lymphocytes （CD4+） after treatment （P<0.01）. Compared with the control group after treatment， the observation group showed greater improvement in these markers （P<0.05）. In terms of inflammatory markers， both groups had a significant decrease compared with those before treatment （P<0.01）. The observation group exhibited lower levels of high-sensitivity C-reactive protein （hs-CRP）， interleukin-6 （IL-6）， and procalcitonin （PCT） than the control group after treatment （P<0.05）. There was no statistically significant difference in imaging efficacy evaluation and clinical outcomes between the two groups. No adverse events were reported in either group during the treatment period. ConclusionChonglian oral liquid combined with standard western medical treatment significantly improves clinical symptoms， shortens fever abatement and nucleic acid negative conversion time， regulates immune function， and inhibits inflammatory responses in patients with mild-to-moderate COVID-19， leading to improved clinical efficacy.
Objective: To investigate the factors influencing total bilirubin elevation and its correlation with UGT1A1 gene polymorphism in the early postoperative period of transjugular intrahepatic portosystemic shunt (TIPS). Methods: 104 cases with portal hypertension and esophageal variceal hemorrhage (EVB) treated with elective TIPS treatment were selected as the study subjects and were divided into a bilirubin-elevated group and a normal bilirubin group according to the total bilirubin elevation level during the early postoperative period. Univariate analysis and logistic regression were used to analyze the factors influencing total bilirubin elevation in the early postoperative period. PCR amplification and first-generation sequencing technology were used to detect the polymorphic loci of the UGT1A1 gene promoter TATA box, enhancer c.-3279 T > G, c.211G > A, and c.686C > A. Logistic regression was used to analyze the correlation of four locus alleles and genotypes with elevated total bilirubin in the early postoperative period. Results: Among the 104 cases, 47 patients were in the bilirubin elevated group, including 35 males (74.5%) and 12 females (25.5%), aged (50.72 ± 12.56) years. There were 57 cases in the normal bilirubin group, including 42 males (73.7%) and 15 females (26.3%), aged (51.63 ± 11.10) years. There was no statistically significant difference in age (t = -0.391, P = 0.697) and gender (χ(2) = 0.008, P = 0.928) between the two groups of patients. Univariate analysis revealed that preoperative alanine transaminase (ALT) level (χ(2) = 5.954, P = 0.015), total bilirubin level (χ(2) = 16.638, P < 0.001), MELD score (χ(2) = 10.054, P = 0.018), Child-Pugh score (χ(2) = 6.844, P = 0.022), and postoperative portal vein branch development (χ(2) = 6.738, P = 0.034) were statistically significantly different between the two groups. Logistic regression analysis showed that preoperative ALT level, total bilirubin level, and portal vein branch development after TIPS were correlated with the elevated total bilirubin in the early postoperative period. The polymorphism of the c.211G > A locus of the UGT1A1 gene correlation had elevated total bilirubin in the early postoperative period of TIPS. The risk of elevated total bilirubin was increased in the population carrying allele A (P = 0.001, OR = 4.049) in the early postoperative period. Allelic polymorphisms in the TATA box promoter region and enhancer c.-3279 T > G and c.686C > A had no statistically significant difference between the bilirubin-elevated group and the normal bilirubin group. Conclusion: The preoperative ALT level, total bilirubin level, and portal vein branch development are correlated with the elevated total bilirubin in early postoperative patients. The polymorphisms of the UGT1A1 gene and enhancer c.211G > A are correlated with the occurrence of elevated total bilirubin in the early postoperative period of TIPS. Allele A carrier may have a higher risk of elevated total bilirubin in the early postoperative period.

Objective To rapidly explore the chemical components of Xiaotan Tongfu formula, and to provide scientific basis for the basic research and clinical treatment of the formula. Methods Analysis was performed on an Agilent 1290 ultra-performance liquid chromatography system coupled with an Agilent 6530 accurate quality Q-TOF/MS system, by using a Waters ACQUITY UPLC BEH C18 column (2.1 mm × 100 mm, 1.7 μm), with a gradient elution applying 0.1% aqueous formic acid solution and acetonitrile as a mobile phase. The flow rate was 0.3 ml/min. The column temperature was 30°C. The injection volume was 1 μl, and the detection wavelength was 254 nm. Mass spectrometry (MS) data were collected in both positive and negative ESI ion modes. Components in the formula were identified by using the in-house compound database, and comparing the retention time (tR), MS1 and MS2 data with the standard compounds, and the online compound MS database. Results A total of 55 compounds were identified from Coptis coptidis, Pseudomonas solani, Rhubarb, Araceae artemisiae and Pinellia chinensis. Conclusion The established UHPLC-Q-TOF/MS method could systematically and accurately identify the chemical components from Xiaotan Tongfu formula, and provided a reference for the quality marker selection and the research on the active ingredient.
Eosinophil extracellular traps (EETs), an important pathway of eosinophil to exert its effects, are composed of DNA fibers, histone and eosinophil granule proteins. Recently, many researches have shown that EETs play an important role in the genesis and development of respiratory diseases including asthma, allergic bronchopulmonary aspergillosis and chronic obstructive pulmonary disease. EETs can directly damage airway epithelial cells, promote airway inflammation and airway hypersecretion, increase the stickiness of secretions and induce the generation of autoantibody, helping eosinophils and their products participate in a cascade of events leading to inflammation and disease. Researches on EETs can also be helpful in investigating new targets for the treatment of chronic airway diseases.
Irritable bowel syndrome is a gastrointestinal disorder of unknown etiology characterized by widespread, chronic abdominal pain associated with altered bowel movements. Increasing amounts of evidence indicate that injury and inflammation during the neonatal period have long-term effects on tissue structure and function in the adult that may predispose to gastrointestinal diseases. In this study we aimed to investigate how the epigenetic regulation of DNA demethylation of the p2x7r locus guided by the transcription factor GATA binding protein 1 (GATA1) in spinal astrocytes affects chronic visceral pain in adult rats with neonatal colonic inflammation (NCI). The spinal GATA1 targeting to DNA demethylation of p2x7r locus in these rats was assessed by assessing GATA1 function with luciferase assay, chromatin immunoprecipitation, patch clamp, and interference in vitro and in vivo. In addition, a decoy oligodeoxynucleotide was designed and applied to determine the influence of GATA1 on the DNA methylation of a p2x7r CpG island. We showed that NCI caused the induction of GATA1, Ten-eleven translocation 3 (TET3), and purinergic receptors (P2X7Rs) in astrocytes of the spinal dorsal horn, and demonstrated that inhibiting these molecules markedly increased the pain threshold, inhibited the activation of astrocytes, and decreased the spinal sEPSC frequency. NCI also markedly demethylated the p2x7r locus in a manner dependent on the enhancement of both a GATA1-TET3 physical interaction and GATA1 binding at the p2x7r promoter. Importantly, we showed that demethylation of the p2x7r locus (and the attendant increase in P2X7R expression) was reversed upon knockdown of GATA1 or TET3 expression, and demonstrated that a decoy oligodeoxynucleotide that selectively blocked the GATA1 binding site increased the methylation of a CpG island in the p2x7r promoter. These results demonstrate that chronic visceral pain is mediated synergistically by GATA1 and TET3 via a DNA-demethylation mechanism that controls p2x7r transcription in spinal dorsal horn astrocytes, and provide a potential therapeutic strategy by targeting GATA1 and p2x7r locus binding.

The occurrence and development of colorectal cancer as a complex disease involves the abnormality of multiple signaling pathways. Chinese medicine regulates a variety of biological processes such as tumor cell differentiation， cell proliferation， apoptosis， cell metastasis， cell cycle， and tumor angiogenesis to prevent the occurrence of colorectal cancer （inflammation-cancer transformation）， tumor metastasis （common metastases of colorectal cancer include liver metastasis， lung metastasis， bone metastasis， and lymphatic metastasis）， and multidrug resistance induced by chemotherapy， treat primary tumors， and mitigate the toxic and side effects of chemotherapy. The pathways of Chinese medicine in the treatment of colorectal cancer have been intensively studied. The available studies have demonstrated that Patrinia villosa Juss and Pien Tze Huang can regulate the Notch pathway to inhibit the growth of colorectal cancer cells. Curcumin and Quyu Jiedu decoction regulate Hippo pathway to inhibit the survival， proliferation， invasion， and migration of colorectal cancer cells. Kujin tea and luteolin suppress the proliferation of colorectal cancer cells and protect intestinal barrier by regulating Kelch-like epichlorohydrin-associated protein-1 （Keap1）/nuclear factor E2-related factor 2 （Nrf2）/antioxidant response element （ARE） pathway. Icariin and ginkgolide C can regulate hepatocyte growth factor （HGF）/cellular-mesenchymal to epithelial transition factor （c-Met） pathway to induce apoptosis of colorectal cancer cells and prevent liver metastasis of colorectal cancer. Verbascoside and apigenin regulate p53 protein to promote apoptosis of colorectal cancer cells， reverse thymidylate synthase （TS）， and alleviate the multidrug resistance of colorectal cancer. Resveratrol and lycopene regulate insulin-like growth factor （IGF）/insulin-like growth factor receptor 1 （IGF1R） pathway to inhibit cancer cell metastasis and prolong disease-free survival. Cordycepin and Galla Chinensis water extract activate AMP-activated protein kinase （AMPK） pathway to inhibit the migration and invasion of cancer cells as well as the lung metastasis of colorectal cancer. The above summary aims to provide reference for the in-depth research on the treatment of colorectal cancer with Chinese medicine and inspire new research ideas.
PURPOSE: The efficacy and safety of super-mini percutaneous nephrolithotomy (SMP, 14 Fr) was compared with mini percutaneous nephrolithotomy (MPCNL, 16 Fr) for the treatment of upper urinary tract stones in children (< 14 years old). METHODS: Clinical data of 133 paediatric patients with upper urinary tract stones treated with SMP or MPCNL between May 2012 and May 2019 were retrospectively analysed. The patients were divided into the SMP and MPCNL groups. Age, height, weight, stone size, operation time, stone-free rate (SFR), postoperative complications, tubeless rate, and length of postoperative hospital stay (LOS) were compared. RESULTS: There were 66 patients (49.6%) in the SMP and 67 patients (50.4%) in the MPCNL group. No significant difference in the median age, weight, height and operation time, and SFR existed between the patients of the two groups. Larger stones were removed via SMP compared to those removed with MPCNL (2.0 vs. 1.5 cm, P = 0.001). LOS for SMP patients was significantly lower than that for the MPCNL patients (2 and 6 days, respectively, P < 0.0001). The tubeless rate for SMP was significantly higher than that for MPCNL (100% vs. 0%, P < 0.0001). Total complication rate of MPCNL was significantly higher than that of SMP (25.3% vs. 7.5%, P = 0.006). No patient required blood transfusion, and septicaemia, and other serious complications did not occur. CONCLUSION: SMP is more effective than MPCNL for treating middle-sized upper urinary tract stones in children, and is associated with a shorter LOS and a higher tubeless rate.

Objective:To evaluate the effects of left ventricular remodeling on systolic synchronization in patients with severe preeclampsia(SPE) by full-volume imaging technology.Methods:One hundred and nine patients with SPE were randomly selected as SPE group in the First Hospital of Shanxi Medical University from December 2016 to December 2019, which were further divided into systolic synchrony(SS) group ( n=35) and systolic dyssynchrony(SD) group( n=74). And 34 healthy pregnant women during the same period were selected as normal pregnancy(NP) group. The clinical datas were collected. Parameters including left ventricular end diastolic volume(LVEDV), left ventricular end systolic volume(LVESV), left ventricular ejection fraction(LVEF), spherical index(SpI), left ventricular mass index(LVMI) and systolic dyssynchrony index(SDI) were obtained by full-volume imaging technology. The effects of left ventricular remodeling on systolic synchronization in patients with SPE were analyzed by bivariate correlation, multiple linear stepwise regression analysis and binary Logistic regression analysis, respectively. Results:①Bivariate correlation analysis showed that LVEDV, LVESV, SpI and LVMI were positively correlated with SDI( r=0.335, 0.361, 0.635, 0.680; all P<0.01). ②After adjustment for age, body mass index, systolic blood pressure, course of hypertension, antihypertensive and antispasmodic treatments, gestational diabetes mellitus, subclinical hypothyroidism, LVEF, multiple linear regression analysis showed that SpI and LVMI were independent predictors of SDI (β=0.228, 0.319; all P<0.01). ③Binary Logistic regression analysis showed that SpI and LVMI were independently correlated with left ventricular systolic dyssynchrony [ OR(95% CI)=1.288(1.039-1.598), 1.102(1.019-1.192); all P<0.05]. Conclusions:Left ventricular remodeling in patients with SPE leads to the decrease of left ventricular systolic synchronization, which can reflect subclinical myocardial dysfunction early. Full volume imaging technology can accurately evaluate left ventricular systolic synchronization in patients with SPE.
Objective:To evaluate the clinical efficacy of Xuebijing combined with human immunoglobulin for the treatment of severe and critically ill patients with coronavirus disease 2019 (COVID-19).Methods:A retrospective study was conducted. The clinical data of 65 patients with severe and critical COVID-19 admitted to Chongqing Public Health Medical Center and Chongqing Three Gorges Central Hospital from January 2020 to March 2020 during the period of supporting to combat COVID-19 by the medical team of the Second Affiliated Hospital of Chongqing Medical University and Chongqing Hospital of Traditional Chinese Medicine were analyzed. According to different treatment regimens, patients were divided into conventional treatment group (conventional antivirus, anti-infection and symptomatic support treatments), Xuebijing group (Xuebijing was applied to patients with elevated inflammatory cytokines) and combination group (Xuebijing combined with human immunoglobulin, human immunoglobulin was applied to patients with low immunity indicated by monitoring results of lymphocytes and their subsets). The improvement of blood routine examination, blood gas analysis, myocardial enzyme spectrum, liver and kidney function, lymphocytes and their subsets and cytokines as well as severity score in three groups before and after treatment were observed. Kaplan-Meier method was used to draw the 28-day survival curve of each group, and the cumulative survival rate among the groups was compared.Results:Among the 65 severe and critically ill COVID-19 patients, only 20 patients received conventional treatment, 22 patients were treated with Xuebijing based on conventional treatment, and 23 patients were treated with Xuebijing combined with human immunoglobulin based on conventional treatment. Before treatment, CD4 + T cell count in combination group was higher than other two groups, and interleukin-6 (IL-6) was lower than other two groups, while other indicators showed no statistically significant differences among the three groups, suggesting that the baseline of the three groups was relatively balanced before treatment. The patients in the conventional treatment group were relieved after treatment, and it was characterized by that the acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score and lactate dehydrogenase (LDH) were significantly lower than those before treatment [APACHEⅡ score: 5.20±2.74 vs. 6.20±1.93, LDH (μmol·s -1·L -1): 4.1±1.0 vs. 4.7±0.9, both P < 0.01], but there was still liver damage, which was manifested as higher aspartate aminotransferase (AST) than that before treatment [U/L: 30.5 (23.8, 41.5) vs. 21.0 (17.0, 34.0), P < 0.05]. In Xuebijing group, the respiratory function and immunity of patients were improved after treatment, and the improvement degree of the ratio of CD4 + T cell was more significant than that in the conventional treatment group (4.86±6.31 vs. -0.95±12.38, P < 0.05). However, the patients still lived with an "inflammatory storm" and liver damage after treatment. It was shown that IL-4 was significantly higher than that before treatment (ng/L: 2.57±1.15 vs. 1.92±1.04, P < 0.05), while albumin (ALB) decreased significantly compared with before treatment [g/L: 33.0 (30.5, 35.6) vs. 36.2 (32.1, 41.4), P < 0.01]. While the treatment of Xuebijing combined with human immunoglobulin could improve patients' respiratory function and enhance their immunity more effectively, it was shown that arterial partial pressure of oxygen (PaO 2), oxygenation index (PaO 2/FiO 2), T lymphocyte count, ratio of CD4 + T cell, CD4 + T cell count, CD8 + T cell count and CD4 +/CD8 + ratio were significantly higher than those before treatment, while ALB, IL-6, APACHEⅡ score and sequential organ failure assessment (SOFA) score were significantly lower than those before treatment. T lymphocyte count, the ratio of CD4 + T cell and IL-6 in combination group were improved more significantly than those in conventional treatment group and Xuebijing group [T lymphocyte count (×10 9/L): 310.68±359.28 vs. 46.54±240.01, 81.59±256.76; ratio of CD4 + T cell: 14.53±14.49 vs. -0.95±12.38, 4.86±6.31; IL-6 (ng/L): -25.53±39.05 vs. -1.75±5.45, 12.78±44.81], PaO 2/FiO 2 was improved more significantly as compared with the Xuebijing group [mmHg (1 mmHg = 0.133 kPa): 146.31±109.73 vs. 59.41±87.70], and the differences were statistically different (all P < 0.05). Conclusion:The combination of Xuebijing and human immunoglobulin for the treatment of patients with COVID-19 can improve patients' respiratory function, reduce "inflammatory storm", enhance immunity, and alleviate severity of patients' condition.
Objective:To analyze the correlation between simple thyroid nodule and blood lipid and glucose metabolism and iodine nutrition level.Methods:A cross-sectional study was conducted by collecting data of the population undergoing epidemiological investigation in Jinshan District, Shanghai from July to December 2015, to calculate the prevalence of thyroid nodules and analyze relevant functional indicators.Results:Simple thyroid nodules were detected in 603 subjects, with a prevalence of 22.6% (603/2 669). There were 358 female patients with simple thyroid nodules, with a prevalence rate of 26.9%, and 245 male patients with simple thyroid nodules, with a prevalence rate of 18.3%. The prevalence of simple thyroid nodule in female was higher than that in male, and the difference was statistically significant (χ 2=27.686, P<0.001). In addition, the prevalence of simple thyroid nodules increased with age (13.1% (92/704) and 20.2% (104/514) and 25.1% (145/578) and 24.4% (107/439) and 36.3% (98/270) and 34.8% (57/164), χ 2=83.872,P<0.001). In the ≤30 years group (8.0% (30/704) vs. 18.8% (62/331), χ 2=35.716, P<0.001), >30 to ≤40 years old group (14.1% (37/263) vs. 26.7% (67/251), χ 2=12.683, P<0.001), >60 to ≤70 years old group (26.2% (33/126) vs. 45.1% (65/144), χ 2=10.435, P<0.001), and the 70-year-old group (24.4% (21/86) vs. 46.2% (36/78), χ 2=8.521, P<0.001). The prevalence of simple thyroid nodules in males was lower than that in females. In the simple positive thyroid nodule group, Fasting blood glucose (5.12 (4.80, 5.69) and 5.02 (4.72, 5.48)), total cholesterol (1.24 (0.85, 1.86) and 1.13 (0.77, 1.76)), triglyceride (4.77 (4.09, 5.48) and 4.49 (3.92, 5.16)), low density lipoprotein((2.79 (2.26, 3.36) and 2.63 (2.19, 3.16)), and high density lipoprotein cholesterol (1.41 (1.18, 1.66) and 1.35 (1.13, 1.61)) were higher than those in the negative group ( U values were 554 818, 578 468, 535 622, 556 067 and 567 960, respectively, all P<0.01). The BMI index grade distribution of thyroid nodule positive group was higher than that of negative group, and the difference was statistically significant (3.7% (77/2 066), 50.1% (1 034/2 066), 32.4% (669/2 066), 13.8% (286/2 066), 3.2% (19/603), 43.6% (263/603), 38.1% (230/603), 15.1% (91/603), χ2=9.5201, P=0.023). The prevalence of simple thyroid nodules was significantly lower in the iodized salt group than in the non-iodized salt group (20.7% (436/2 102) vs. 29.5% (167/567), χ 2=19.376, P<0.001). The urinary iodine level in the positive thyroid nodule group was significantly lower than that in the negative group (148.4(100.2, 213.7) vs. 169.5(115.4, 241.75), U=545 129.5, P<0.001). After Logistic regression screening, age ( OR=1.57, 95% CI: 1.292-1.908, P<0.001), gender ( OR=1.278, 95% CI: 1.193-1.368, P<0.001), BMI grade ( OR=1.166, 95% CI: 1.022-1.330, P=0.022), total cholesterol ( OR=1.105, 95% CI: 1.005-1.214, P=0.040), iodized salt ( OR=0.689, 95% CI: 0.556-0.854, P=0.001) were independent influencing factors of thyroid nodule. Conclusion:The prevalence of simple thyroid nodules in Shanghai is relatively low. Age, sex, BMI level, total cholesterol and iodized salt are independent factors causing thyroid nodules. In addition, blood glucose level may also be related to the prevalence of thyroid nodules.
Objective:To investigate the predictive value of postoperative C-reactive protein for serious complications after Da Vinci robotic surgical system radical gastrectomy of gastric cancer.Methods:The retrospective case-control study was conducted. The clinicopathological data of 298 patients with advanced gastric cancer who underwent Da Vinci robotic surgical system radical gastrectomy in the 940th Hospital of Joint Logistics Support Force of Chinese People's Liberation Army from January 2017 to June 2019 were collected. There were 253 males and 45 females, aged from 24 to 86 years, with a median age of 60 years. Of the 298 patients, 275 cases underwent no serious postoperative complications and 23 cases underwent serious postoperative complications. Observation indicators: (1) serious postoperative complications; (2) analysis of risk factors for serious postoperative complications after Da Vinci robotic surgical system radical gastrectomy of gastric cancer; (3) performance evaluation of the predictive indicators. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the rank sum test. Univariate analysis was conducted using the chi-square test. Multivariate analysis was conducted using Logistic regression model. The receiver operating characteristic curve was drawn and the area under curve (AUC) was used to compare and estimate the efficiency of diagnostic criteria. The value of Youden index was used to determine the optimal cut-off point. Results:(1) Serious postoperative complications: of the 298 patients, 23 cases underwent complications classified ≥grade Ⅲa of Clavien-Dindo classifica-tion, including 10 cases with grade Ⅲa complications, 7 cases with grade Ⅲb complications, 4 cases with grade Ⅳa complications, 1 case with grade Ⅳb complications and 1 case with grade Ⅴ complications. (2) Analysis of risk factors for serious postoperative complications after Da Vinci robotic surgical system radical gastrectomy of gastric cancer. Results of univariate analysis showed that operation time, indicators of C-reactive protein concentration and neutrophil count at post-operative day 1, and indicators of C-reactive protein concentration, white blood cells count, neutrophil count and platelet count at postoperative day 3 and pathological stage were related factors affecting serious complications for advanced gastric cancer after Da Vinci robotic surgical system radical gastrectomy ( χ2=7.671, 4.504, 5.045, 48.293, 9.575, 15.436, 13.731, 9.537, P<0.05). Results of multivariate analysis showed that the operation time ≥250 minutes, the concentration of C-reactive protein at postoperative day 3 ≥16.65 mg/dL, the neutrophil count at postoperative day 3 ≥8.167×10 9/L, the platelet count at postoperative day 3 ≥218×10 9/L and the pathological stage of tumor as stage Ⅱ and stage Ⅲ were independent risk factors affecting serious complications for advanced gastric cancer after Da Vinci robotic surgical system radical gastrectomy ( odds ratio=3.721, 16.084, 6.056, 6.893, 12.455, 95% confidence interval: 1.032-13.421, 4.657-55.547, 1.073-34.163, 1.798-26.423, 1.338-115.930, P<0.05). (3) Performance evaluation of the predictive indicators: the C-reactive protein concentration at postoperative day 3 was a high-performance predictor with the AUC as 0.851 (95% c onfidence interval: 0.780-0.921, P<0.05) and neutrophil count and platelet count at postoperative day 3 were low-performance predictors with the AUC as 0.659 and 0.666 (95% confidence interval: 0.570-0.748 and 0.581-0.750, P<0.05). Conclusion:The C-reactive protein concentration ≥16.65 mg/dL at postoperative day 3 is a high performance predictive indicator for serious complications after Da Vinci robotic surgical system radical gastrectomy of gastric cancer.
Objective To investigate the clinical value of alpha-fetoprotein (AFP) combined with gamma-glutamyl transpeptidase (GGT)/aspartate aminotransferase (AST) ratio in the diagnosis of hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC). Methods A total of 352 subjects who received treatment or underwent physical examination in Renmin Hospital of Wuhan University from January 15 to June 15, 2020, were enrolled, among whom there were 86 healthy controls (HC group), 68 patients with chronic hepatitis B (CHB group), 69 patients with liver cirrhosis (LC group), and 129 patients with HCC (HCC group), and a retrospective analysis was performed for the serological test results of all subjects. An analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t -test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of continuous data with skewed distribution between multiple groups, and the Nemenyi method was used for further comparison between two groups. A binary logistic regression analysis was used to calculate predictor variables; a receiver operating characteristic (ROC) curve was plotted for AFP, GGT/AST, and the predictor variables used alone or in combination, and the area under the ROC curve (AUC), sensitivity, and specificity were calculated; the Z test was used for comparison of AUC. Results The HCC group had significantly higher GGT/AST ratio and AFP than the other groups (all P < 0.05). The ROC curve analysis showed that AFP combined with GGT/AST ratio had a significantly higher AUC than AFP alone in the HCC group vs the LC group, the HCC group vs the HC+CHB+LC groups, and the HCC group vs the CHB+LC groups ( Z =2.684, 2.241, and 2.415, P =0.007, 0.025, and 0.016). Conclusion AFP combined with GGT/AST ratio can improve the clinical diagnostic performance of HBV-related HCC and thus has a certain diagnostic value.
Objective:To investigate the diagnostic and prognostic value of the growth differentiation factor 15 (GDF15) and the procalcitonin (PCT) in sepsis.Methods:A total number of 137 patients with sepsis (considered as the sepsis group) and 59 patients with inflammatory infection but not diagnosed as sepsis (the non-sepsis group) received treatment in intensive care unit of Renming Hospital of Wuhan University were collected from July 2020 to January 2021, and 62 cases of healthy physical examination (control group) were simultaneously chosen as control. Sepsis patients were divided into two groups (death group [ n=48] and survival group [ n=89]) according to their 28-day′s survival. The serum levels of GDF15, PCT, C-reactive protein (CRP), interleukin-6 (IL-6) and interleukin-10 (IL-10) were examined, and the levels of each index, was dynamically monitored on the 1st, 3rd and 7th day after admission. The differences of the two indicators between different groups were compared by non-parametric test. The correlation between GDF15 and PCT was analyzed by Spearman correlation test. The receiver operating characteristic (ROC) curve was drawn to evaluate the diagnostic and prognostic value of the two indicators for sepsis. Results:The levels of GDF15 in the sepsis group, non-sepsis group and control group were 3.22 (1.39, 6.31) μg/L, 0.84 (0.21, 1.66) μg/L and 0.11 (0.09, 0.13) μg/L, respectively. The levels of PCT were 13.10 (1.99, 50.25) μg/L, 0.24 (0.13, 0.68) μg/L and 0.05 (0.03, 0.10) μg/L, respectively. The levels of CRP were 115.80 (26.40, 184.07) mg/L, 24.20 (11.30, 53.20) mg/L and 0.50 (0.50, 2.76) mg/L, respectively. The levels of IL-6 were 68.26 (21.59, 255.46) ng/L, 33.20 (10.81, 89.27) ng/L and 8.82 (7.33, 11.23) ng/L, respectively. The levels of IL-10 were 11.30 (5.88, 25.50) ng/L, 9.34 (5.65, 16.90) ng/L and 4.94 (4.31, 5.31) ng/L, respectively. The GDF15, PCT, CRP and IL-6 of the sepsis group were significantly higher than those of the non-sepsis group (The U values were 67.681, 86.034, 44.164 and 38.934, respectively, with P values less than 0.05) and the control group (The U values were 136.475, 138.667, 120.701 and 100.886, respectively, with P values less than 0.001). There was no significant difference in IL-10 between sepsis group and nonsepsis group, but it was higher than that of control group ( U=80.221, P<0.001). There was a positive correlation between GDF15 and PCT in patients with sepsis, and the spearman correlation coefficient was 0.234 ( P=0.006). The GDF15 of the death group and the survival group were 5.49 (3.60, 8.25) μg/L and 2.03 (1.06, 3.69) μg/L, and the PCT levels were 26.45 (11.23, 94.25) μg/L and 9.08 (1.33, 22.75) μg/L, respectively. GDF15 and PCT in the death group were significantly higher than those in the survival group ( U values were 3 305.500 and 3 060.000, respectively, and P values were both less than 0.001). The GDF15 and PCT levels in the death group were higher than those in the survival group on the 1st, 3rd and 7th day of dynamic monitoring ( P<0.05), however, the level of CRP and IL-10 were not significantly different ( P>0.05). The level of IL-6 in the death group was not significantly different from that of the death group on 1st day, but was higher than that of the survival group on the 3rd and 7th day ( P<0.05). The area under the curve (AUC) of GDF15, PCT, CRP, IL-6 and IL-10 alone and in the combined diagnosis of sepsis were 0.899, 0.938, 0.874, 0.789, 0.698 and 0.962, respectively. The combined detection of AUC was better than a single index; the GDF15, PCT, CRP, IL-6 and IL-10 alone and combined detection of sepsis prognosis AUC were 0.774, 0.716, 0.522, 0.623, 0.520 and 0.839, respectively, the combined detection of AUC is also better than single index. Conclusions:GDF15 and PCT have good clinical reference value in the differential diagnosis and prognosis of sepsis. The combination of indicators has a higher clinical value. GDF15 may become a biomarker for the diagnosis and prognosis of sepsis.
Hypertension is a risk factor for cardiovascular diseases. Many studies have found that exercise training, including aerobic exercise, resistance exercise and combined aerobic and resistance exercise, is beneficial for hypertension control. This article reviews the effect of different types of exercise training on hypertension and its underlying mechanism.
Objective:To analyze the equity of community health resource allocation available to the elderly in Shanghai to provide a reference for the optimization of their allocation and to ensure the basic medical needs of the elderly.Methods:116 community health service centers were selected as research objects. Based on the human resources and financial inputs for community health, the Gini coefficient and Theil index were used to analyze the equity of community health resource allocation in Shanghai from the service population and across geographical dimensions.Results:The Gini coefficients of in-service health technicians and total financial compensation, as based upon the dimension of serving the elderly population, were 0.116 and 0.251, respectively, while the Gini coefficients based on the geographical dimension were 0.483 and 0.329 (respectively). The results of the Theil index analysis are relatively consistent with the Gini coefficient. The equity of health human resource allocation is slightly better than that of financial investment, and the equity of health resource allocation population is better than that concerning geography. Regional differences are the main factors regarding the equity of health resource allocation of the elderly community based on geographical factors (71.47%-86.71%), intra-regional differences were the main source of equity differences in community health resources allocation based on the elderly population (52.52%-89.44%).Conclusion:The allocation structure of community health resources for the elderly in Shanghai is, on the whole, fair; but, the differences between population equity and geographical equity, and between and within regional plates, cannot be ignored.
