ABSTRACT

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2, is a major public health issue. The epidemic is unlikely to be contained until the global launch of safe and effective vaccines that could prevent serious illnesses and provide herd immunity. Although most patients have mild flu-like symptoms, some develop severe illnesses accompanied by multiple organ dysfunction. The identification of pathophysiology and early warning biomarkers of a severe type of COVID-19 contribute to the treatment and prevention of serious complications. Here, we review the pathophysiology, early warning indicators, and effective treatment of Chinese and Western Medicine for patients with a severe type of COVID-19.

ABSTRACT

OBJECTIVE@#In traditional Chinese medicine, the herbal pair, Radix Achyranthis Bidentatae (RAB) and Eucommiae Cortex (EC), is widely used to treat osteoporosis. Herein, we determined whether this herbal pair can be used to ameliorate glucocorticoid (GC)-induced osteoporosis (GIOP) and find its optimal dosage in zebrafish.@*METHODS@#The characteristics of the aqueous extract of RAB and EC were separately characterized using high-performance liquid chromatography. Osteoporosis was induced in 5-day post-fertilization zebrafish larvae by exposing them to 10 μmol/L dexamethasone (Dex) for 96 h. Seven combinations of different ratios of RAB and EC were co-administered. Treatment efficacy was determined by calculating zebrafish vertebral area and sum brightness, via alizarin red staining, and by detecting alkaline phosphatase (ALP) activity. Multiple regression analysis was conducted to test the optimal dosage ratio.@*RESULTS@#According to the Chinese Pharmacopoeia (2015), β-ecdysone (β-Ecd) is a major bioactive marker in RAB extract, while pinoresinol diglucoside (PDG) is the major marker in EC extract. Both of β-Ecd and PDG content values aligned with the Chinese Pharmacopoeia standards. Treatment with 10 μmol/L Dex reduced zebrafish vertebral area, sum brightness, and ALP activity, but RAB and EC attenuated these effects. Combining 50 µg/mL RAB and 50 µg/mL EC was optimal for preventing GIOP in zebrafish. Reverse transcription-quantitative polymerase chain reaction was used to evaluate the mRNA expression of osteogenesis-related genes. A treatment of 10 μmol/L Dex decreased runt-related transcription factor 2 (Runx2), osteogenic protein-1 (OP-1), bone γ-carboxyglutamic acid-containing protein (BGLAP), and β-catenin levels. This effect was counteracted by RAB and EC co-treatment (P < 0.05). Additionally, the effect of using the two herbal extracts together was better than single-herb treatments separately. These results demonstrated that RAB and EC preserve osteoblast function in the presence of GC. The best mass ratio was 1:1.@*CONCLUSION@#RAB and EC herbal pair could ameliorate GC-induced effects in zebrafish, with 1:1 as the optimal dosage ratio.

ABSTRACT

Objective@#To analyze the etiological characteristics of an outbreak of Campylobacter foodborne disease in a middle school in Suzhou City, so as to provide insights into the identification of pathogenic factors of Campylobacter foodborne disease outbreaks.@*Methods@#Eighteen anal swabs from patients, 10 anal swabs from canteen workers, 43 food samples, 2 drinking water samples, 2 food original material samples and 31 environmental samples were collected, and the pathogens were rapidly screened using the gastrointestinal infection detection strip. The pathogens were isolated and cultured using the double-pore filtration membrane method, and cluster analysis of bacterial isolates was performed using pulsed field gel electrophoresis ( PFGE ). In addition, the susceptibility of Campylobacter isolates to antibiotics was tested using the Campylobacter agar dilution method.@*Results@#A total of 63 cases with Campylobacter infections were reported, and the major clinical symptoms included diarrhea ( 51 cases, 80.95% ) and fever ( 39 cases, 61.90% ), while no inpatients or deaths were found. Twelve Campylobacter-positive samples were detected, including 11 anal swabs sampled from patients and one food original material sample. Among the 11 positive anal swabs, there were 10 samples positive for Campylobacter jejuni and one sample positive for C. coli, and of the one positive food original material, C. coli was identified. PFGE analysis showed that 10 C. jejuni isolates of had 100.0% homology, and these 10 isolates were 100.0% resistant to naphthyridic acid, ciprofloxacin and tetracycline, appearing multidrug resistance.@*Conclusions@#This is an outbreak of foodborne disease caused by C. jejuni infections. Gastrointestinal infection detection strips, double-pore filtration membrane and PFGE typing are rapid and accurate to identify pathogenic factors.

ABSTRACT

Background/Aims@#Antidepressants are effective in patients with functional dyspepsia (FD). However, stigma associated with FD and antidepressants may affect treatment adherence. This study aims to explore possible communication strategies to alleviate stigma and improve adherence in patients with FD. @*Methods@#In this randomized, single-center, and single-blind trial, 160 patients with FD initiating antidepressant treatment were recruited. Different communication strategies were performed when prescribing antidepressants. Participants in Group 1 were told that brain is the “headquarters” of gut, and that antidepressants could act as neuromodulators to relieve symptoms of FD through regulating the functions of gut and brain. Participants in Group 2 were told that antidepressants were empirically effective for FD. Stigma scores, medication-related stigma, treatment compliance, and efficacy were analyzed. @*Results@#After 8-week antidepressant treatment, the proportion of patients with FD with decreased stigma scores in Group 1 was significantly higher than in Group 2 (internalized stigma: 64.10% vs 12.00%; perceived stigma: 55.13% vs 13.33%; P < 0.01). Medication-related stigma was lower in Group 1 than in Group 2 (P < 0.05 for 3 of 4 questions). Concurrently, patients in Group 1 had better treatment compliance (0.71 ± 0.25 vs 0.60 ± 0.25, P < 0.01) and efficacy. In Group 1, participants with decreased post-treatment stigma scores showed better treatment compliance and efficacy than those with non-decreased scores. Decrease in stigma scores positively correlated with treatment compliance. @*Conclusion@#Improving knowledge of patients with FD of the disease and antidepressants via proper communication may be an effective way to alleviate stigma and promote adherence.

ABSTRACT

Background@#Sentinel lymph node (SLN) mapping has been recommended as an alternative staging approach to lymphadenectomy for apparent uterine-confined endometrial cancer (EC). However, the prognostic value of SLN mapping alone instead of systematic lymphadenectomy on EC patients remains unclear. @*Methods@#A multi-center, open label, non-inferiority randomized controlled trial has been designed to identify if SLN mapping alone is not inferior to pelvic lymphadenectomy on prognosis of patients with intermediate-high-risk EC clinically confined to uterus. Eligible patients will be 1:1 randomly assigned to accept SLN mapping or pelvic lymphadenectomy. The primary endpoint is the 2-year progression-free survival (PFS). The second points are the 5-year PFS, 5-year overall survival, surgery-related adverse events and life quality. A total of 780 patients will be enrolled from 6 hospitals in China within 3-year period and followed up for 5 years.

ABSTRACT

Objective:To determine the value of ultrasonographic measurement of submental soft tissue distance in predicting poor ventilation with laryngeal mask airway (LMA).Methods:A total of 272 American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients, aged 25-78 yr, weighing 40-85 kg, with mechanical ventilation time 30-120 min, scheduled for elective lower limb vascular surgery or lithotripsy under general anesthesia with LMA, were selected.The parameters of submental soft tissue of tongue thickness (TT), distance from skin to the hyoid bone (DSHB), distance from skin to epiglottis midway (DSEM) and distance from skin to anterior commissure of the vocal cords (DSAC) were measured using ultrasonography before operation.The type of LMA was chosen according to the instruction book.The development of failure of LMA placement at the first attempt, air leakage around LMA cuff during mechanical ventilation, peak airway pressure >20 cmH 2O and gastric insufflation detected by ultrasonography were recorded.The development of one or more adverse events mentioned above was considered to be poor ventilation.The patients were divided into normal ventilation group (N group) and poor ventilation group (P group) according to whether poor ventilation occurred.The receiver operating characteristic curve for ultrasonographic measurement of submental soft tissue distance in predicting poor ventilation with LMA was drawn, and the area under the curve (AUC) and 95% confidence interval (CI), sensitivity and specificity and cut-off value were calculated.The risk factors of which P values were less than 0.05 would enter the logistic regression analysis to stratify the risk factors for poor ventilation with LMA. Results:The AUC for TT, DSHB, DSEM and DSAC measured using ultrasonography in predicting poor ventilation with LMA (95%CI) was 0.866 (0.813-0.919), 0.755 (0.683-0.827), 0.835 (0.772-0.899) and 0.705 (0.628-0.782) ( P<0.05 or 0.01), respectively.The results of logistic regression analysis showed that TT≥6.140 cm, DSHB≥1.145 cm, DSEM≥2.175 cm and DSAC≥1.075 cm were risks factor for poor ventilation with LMA. Conclusion:Ultrasonographic measurement of TT, DSHB, DSEM and DSAC can predict the development of poor ventilation with LMA.

ABSTRACT

Objective:To explore the necessity of lowering the cut-off value of alanine aminotransferase (ALT) in identifying chronic HBV infection patients with significant liver histological changes.Methods:The clinical data of 123 chronic HBV infection patients with normal ALT according to domestic criteria who underwent liver biopsy in the Department of Hepatology of Taizhou People’s Hospital from June 2016 to March 2021 were analyzed retrospectively. According to the cut-off ALT values recommended by 2018 version of AASLD guidelines (male 35 U/L, female 25 U/L), the patients were divided into two groups: high normal value group (HNALT, ALT≥AASLD and<domestic standard) and normal low value group (LNALT, ALT<AASLD value). The cases with significant liver histological changes (G/S≥2) were compared between the two groups. Univariate and multivariate Logistic regression analysis were used to explore the risk factors of G/S≥2.Results:There were 68(68/123, 55.3%) cases with significant liver histological changes (G/S≥2) in this series. Among 83 patients in the LNALT group, there were 35 case of G≥2 (42.2%), 26 cases of S≥2 (31.3%) and 39 cases of G/S≥2 (47.0%); while among 40 patients in the HNALT group, there were 27 cases of G≥2 (67.5%), 21 cases of S≥2 (52.5%), and 29 cases of G/S≥2 (72.5%), respectively. There were significant differences between the two groups ( χ2=6.928, 5.126 and 7.107, all P values <0.05). Univariate analysis showed that ALT at high normal values ( χ2=7.107), albumin levels ( t=2.248), glutamyltransferase ( Z=-2.885) and international normalized ratio (INR) ( t=-3.152) were significantly associated with liver histological changes in patients ( P<0.05 ro <0.01). Multivariate Logistic regression analysis showed that ALT at high normal value ( OR=3.492, 95% CI 1.369-8.907) and INR ( OR=1.529, 95% CI 1.054-2.218) were independent risk factors of significant liver histological changes. Conclusion:Lowering the cut-off value of ALT may contribute to identify patients who potentially need antiviral treatment. It is recommended that patients with high normal value of ALT according to domestic criteria should undergo liver biopsy or non-invasive liver fibrosis examination to evaluate the histological changes of the liver and treat them if necessary.

ABSTRACT

Objective:To explore the epidemiological characteristics of inpatients with tibial pilon fracture in The Third Hospital of Hebei Medical University from 2016 to 2019.Methods:The data of all the patients who had been hospitalized for pilon fracture from January 2016 to December 2019 in The Third Hospital of Hebei Medical University were collected using the medical image computer archiving and transmission system and the medical record query system. The patients' age, gender, occupation, residence, season, cause of injury, Rüedi-Allg?wer classification, and AO classification were analyzed.Results:A total of 234 inpatients with tibial pilon fracture were collected, including 179 males and 55 females, with a ratio of male to female of 3.3∶ 1. The prevalence age ranged from 41 to 50 years in male patients (31.3%, 56/179) and from 51 to 60 years in female patients (25.5%, 14/55). In the 234 patients, farmers (101 cases, 43.2%), rural area (166 cases, 70.9%) and spring season (77 cases, 32.9%) accounted for a higher proportion. The proportions of high-altitude falling (41.0%, 96/234) and high-energy injury (61.5%, 144/234) were the highest. Of the 234 patients by the Rüedi-Allg?wer classification, 23 (9.8%) had type Ⅰ fracture, 90 (38.5%) type Ⅱ fracture, and 121 (51.7%) type Ⅲ fracture, with type Ⅲ fracture prevalent in males (58.1%, 104/179) and type Ⅱ fracture prevalent in females (16.4%, 9/55). Of the 234 patients by the AO classification, 131 (56.0%) had type 43B fracture and 103 (44.0%) type 43C fracture, with a higher proportion of type 43B fractures in women (67.3%, 37/55) than in men (52.5%, 94/179). In type 43B fractures, type 43B3 (43.5%, 57/131) and type 43B3.3 (75.4%, 43/57) were the most common; in type 43C fractures, type 43C3 (74.8%, 77/103) and type 43C3.3 (51.9%, 40/77) were the most common.Conclusions:In the recent 4 years in The Third Hospital of Hebei Medical University, pilon fractures increased year by year and occurred more frequently in spring. They were more common in farmers and in the rural areas. They prevailed in the patients aged from 41 to 50 years. The Rüedi-Allg?wer type Ⅲ fractures and the AO type 43B fractures were the most common.

ABSTRACT

Objective:To investigate the relationship between antibacterial treatment scheme and prognosis, and to analyze the mortality risk factors of bloodstream infection with carbapenem-resistant Klebsiella pneumoniae(CRKP).Methods:A retrospective case-control study was conducted. The CRKP isolated from clinical venous blood samples in the First Medical Center, Chinese PLA General Hospital between January 1, 2013 and December 31, 2018(not included from January 1, 2016 to December 31, 2017) was collected. According to relevant standards, a total of 50 patients with bloodstream infection with CRKP were included. The patients were divided into death (19 cases) or survival (31 cases) group according to their hospitalization outcomes, and clinical data and antibacterial treatment scheme after infection were collected. The clinical features of the two groups and the correlation between different antibacterial treatment regimens and prognosis were compared. Logistics regression model was used to analyze the risk factors for death in CRKP-infected patients.Results:The all-cause mortality rate of patients with CRKP bloodstream infection during hospitalization was 38%(19/50). The age ((66.89±18.13) vs. (55.06±14.39) years old, t=2.555, P=0.014), charlson's comorbidity index ((6.11±2.87) vs. (3.19±1.97), t=4.256, P<0.001) of the death group was higher than that of the survival group. The proportion of patients with chronic obstructive pulmonary disease (42.1%(8/19) vs. 3.2%(1/31), χ2=9.574, P=0.002), Charlson's comorbidity index ≥5 (68.4%(13/19) vs. 22.6%(7/31), χ2=10.314, P=0.001), septic shock (36.8%(7/19) vs. 6.5%(2/31), χ2=5.456, P=0.020), source of lung infection (36.8%(7/19) vs. 9.7%(3/31), χ2=3.868, P=0.049) was higher in death group than those in survival group. Kaplan-meier survival curve showed that the 30-day mortality of appropriate targeted treatment was lower than that of inappropriate targeted treatment ( χ2=8.138, P=0.004). Multivariate analysis showed that septic shock ( OR=56.363, 95% CI: 4.309-737.273, P=0.002) and charlson's comorbidity index ≥5 ( OR=18.605,95% CI: 1.813-190.896, P=0.014) were independent risk factors for mortality in patients with bloodstream CRKP infection. Conclusion:Appropriate targeted therapy can reduce 30-day mortality in patients with CRKP bloodstream infection. In order to reduce the risk of mortality, we should prevent the occurrence of septic shock and strengthen the diagnosis and treatment of patients with Chalson's comorbidity index ≥5.

ABSTRACT

OBJECTIVE To explore the curative effect and mechanism of Yiqi Huoxue decoction in the treatment of coronary heart disease with Qi deficiency and blood stasis syndrome. METHODS The patients with coronary heart dis?ease of Qi deficiency and blood stasis syndrome were treated with Yiqi Huoxue decoction for 3 months, and the changes of cardiac function were observed. 61 serum samples (including 29 cases of disease group and 32 cases of Yiqi Huoxue expression group) were analyzed by non labeled proteomics. The disease group was used as the control group, and the protein with expression level difference of more than 1.2 folds (P<0.05) was screened. The molecular function, biologi?cal pathway and protein interaction of the different proteins were analyzed by bioinformatics, so as to identify the molecu?lar and biological pathway of Yiqi Huoxue decoction in the treatment of coronary heart disease with Qi deficiency and blood stasis syndrome. RESULTS Clinical treatment found that Yiqi Huoxue decoction can improve TCM syndrome score and left ventricular ejection fraction, regulate blood glucose and blood lipid levels, prolong thrombin time, and improve heart function. The results of proteomic quantitative analysis showed that there were 69 proteins with different expression levels in the disease group. Bioinformatics analysis results showed that Yiqi Huoxue decoction may regulate ApoA1, alpha-2 and other proteins to act on HDL assembly, platelet degradation, PI3K Akt signaling pathway, and then play a therapeutic role in coronary heart disease with Qi deficiency and blood stasis syndrome. CONCLUSION Yiqi Huoxue decoction can effectively improved the heart function decline caused by Qi deficiency and blood stasis syn?drome of coronary heart disease. It mainly act on energy metabolism and platelet activation pathway by activating HDL assembly and platelet degradation signal pathway proteins. This study can provide reference for the follow-up treatment mechanism of Qi deficiency and blood stasis syndrome of coronary heart disease.

ABSTRACT

Objective:To investigate the clinical practice of Chinese respiratory therapists (RTs) participating in the treatment of coronavirus disease 2019 (COVID-19) patients and summarize the experience and role of RTs in the treatment of pandemic infectious diseases.Methods:A self-designed questionnaire was used to investigate the RTs who treated COVID-19 patients in 31 provinces, cities and autonomous regions in China. The survey questionnaire included the basic work of RTs, the specific work of the treatment for COVID-19 patients and problems encountered at work.Results:A total of 126 questionnaires were issued and 40 valid questionnaires were collected from RTs who treated COVID-19 patients at 22 COVID-19 designated hospitals in 8 provinces and municipalities. This included 7 hospitals in Wuhan, the epicenter of the epidemic. In their medical team, RTs accounted for 2.9% (1.5%, 6.7%) of medical staff, the working experience of the RTs was about (6.2±5.4) years, the ratio of RTs to beds was about 1∶11 (1∶5, 1∶26), and 85.0% (34/40) of RTs were transferred from other hospitals. 97.5% (39/40) of RTs were involved in formulating individual respiratory care strategies in their medical teams, and they were all involved in the evaluation of respiratory care and decision-making as well as the early identification of deterioration of respiratory function. All RTs [100% (40/40)] indicated that they would actively monitor patients' respiratory status, increase the means and frequency of the monitoring, implement standardized oxygen therapy, prevent ventilator-associated lung injury (VALI), and standardize the management of artificial airway. However, less than 50% of RTs had carried out stress and strain, transpulmonary pressure, partial pressure of end-tidal carbon dioxide (PetCO 2), end-expiratory lung volume, electrical impedance tomography (EIT) and other respiratory function monitoring. 85% of RTs conducted training and education related to respiratory care and formulated relevant standard operating procedures for their medical teams. More than 90% of RTs led the implementation of high-flow nasal cannula oxygen therapy (HFNC), pulmonary protective mechanical ventilation, prone ventilation, pulmonary rehabilitation, airway management, transfer of critical patients, and other respiratory treatment. Conclusions:RTs performed their professional role fully in the assessment, decision-making, and clinical practice in the treatment of COVID-19 patients. However, the manpower shortage of RTs is extremely prominent, the practical experience has provided the basis for the future treatment of infectious respiratory diseases and effectively promoted the development of respiratory care in China.

ABSTRACT

Objective:To investigate clinicians' compliance with the 2018 Surviving Sepsis Campaign (SSC) update "1-hour sepsis Bundle therapy" (1-hour Bundle) when treating patients with Sepsis 3 in the intensive care unit (ICU), and to analyze its impact on patient outcomes.Methods:A multicenter, prospective observational cohort study was conducted. A total of 153 ICU patients in Ziyang First People's Hospital, Ziyang People's Hospital and Yanjiang District People's Hospital who were diagnosed of sepsis by the definition and diagnostic criteria of Sepsis 3 from January 2019 to December 2020 were selected. Among them, 95 patients who had completed 1-hour Bundle were divided into the Bundle compliance group. 58 patients who did not complete the Bundle within 1 hours were classified as the Bundle non-compliance group. The distribution of pathogenic bacteria and infected sites, 1-hour Bundle compliance and 28-day survival in the 3 hospitals were analyzed. Univariate analysis was used to analyze the risk factors affecting the prognostic between the two groups of sepsis patients. Cox regression model was used to draw a 28-day survival curve to evaluate the survival of the patients in the two groups.Results:Among 153 sepsis patients in 3 hospitals, the detection rate of pathogenic bacteria was 61.44% (94/153), and Gram-negative bacteria accounted for 79.79% (75/94). The top 3 infection sites were respiratory system, gastrointestinal tract and urinary system, accounted for 32.0%, 28.1% and 18.3%, respectively. In the 3 hospitals, 62.09% (95/153) of patients fully implemented the 1-hour Bundle. The poorly implemented indicators in the 1-hour Bundle were 1-hour blood microbial culture [77.78% (119/153)] and 1-hour antimicrobial application [79.74% (122/153)]. There was no significant difference in the baseline indicators between Bundle compliance and non-compliance groups. Univariate analysis showed that the main prognostic indicators: 28-day survival rate in the Bundle compliance group was significantly higher than that in the Bundle non-compliance group [80.00% (76/95) vs. 62.06% (36/58), χ2= 6.447, P = 0.014]. Secondary evaluation indicators: mean arterial pressure (MAP) at 6 hours and 24 hours in the Bundle compliance group were significantly higher than those in the Bundle non-compliance group [mmHg (1 mmHg = 0.133 kPa): 78.22±11.25 vs. 69.86±14.04, 79.78±11.45 vs. 75.35±12.90]. However, the median length of in hospital stay in the Bundle compliance group was significantly longer than that in the Bundle non-compliance group [days: 13 (17) vs. 6 (11)], with statistically significant differences (all P < 0.05). Bivariate Logistic regression analysis showed that 6 hours and 24 hours MAP were risk factors affecting the prognosis of patients with sepsis [odds ratio ( OR), 95% confidence interval (95% CI): 1.064 (0.994-1.102), 1.032 (1.003-1.063), both P < 0.05]. Conclusions:The 1-hour Bundle compliance rate of ICU patients with sepsis in 3 hospitals of Ziyang City was 62.09%, and the compliance is still to be improved, especially for the 2 aspects of empirical antimicrobial use and microbial culture retention before antimicrobial use. The 28-day survival rate in the Bundle compliance group was significantly higher than that in the Bundle non-compliance group, suggesting that the 1-hour Bundle regimen can improve the prognosis of patients with sepsis.

ABSTRACT

Objective:To investigate the effects of fluid resuscitation under pulse-indicated continuous cardiac output monitoring on endothelial function, inflammatory indexes and hemodynamics in patients with traumatic shock.Methods:The clinical data of 62 patients with traumatic shock who received treatment in the First Affiliated Hospital of Zhejiang Chinese Medical University, China between July 2019 and July 2020 were retrospectively analyzed. These patients were divided into observation and control groups ( n = 31/group) according to different fluid resuscitation methods. The control group was given conventional fluid resuscitation and the observation group was subjected to guided fluid resuscitation under pulse-indicated continuous cardiac output monitoring. General treatment and nitric oxide, endothelin-1, C-reactive protein, interleukin-6, interleukin-1β, tumor necrosis factor-α, central venous pressure, mean arterial pressure, and central venous oxygen saturation before and 24 hours after treatment as well as complications were compared between the two groups. Results:Time to early resuscitation, duration of mechanical ventilation, intensive care unit length of stay and the length of hospital stay in the observation group were (5.33 ± 0.51) hours, (37.45 ± 4.84) hours, (8.75 ± 1.20) days, (16.85 ± 2.03) days, respectively, which were significantly shorter than those in the control group [(8.14 ± 1.20) hours, (46.06 ± 4.71) hours, (11.46 ± 1.63) days, (20.01 ± 2.41) days, t = 11.999, 7.098, 7.455, 5.584, all P < 0.01). At 24 hours after treatment, serum level of nitric oxide in the observation group was significantly higher than that in the control group [(52.04 ± 3.91) μmol/L vs. (40.25 ± 4.25) μmol/L, t = 11.367, P < 0.01]. Serum level of endothelin-1 in the observation group was significantly lower than that in the control group [(66.95 ± 4.75) ng/L vs. (78.04 ± 7.92) ng/L, t = 6.686, P < 0.01)]. Serum levels of C-reactive protein, interleukin-6, interleukin-1β, tumor necrosis factor-α in the observation group were (8.32 ± 1.56) mg/L, (113.03 ± 15.74) ng/L, (69.82 ± 6.50) ng/L, (42.80 ± 4.32) ng/L, respectively, which were significantly lower than those in the control group [(11.61 ± 1.74) mg/L, (130.42 ± 20.68) ng/L, (81.33 ± 7.30) ng/L, (56.11 ± 6.36) ng/L, t = 7.838, 3.726, 6.556, 9.639, all P < 0.01)]. Mean arterial pressure, central venous pressure and central venous oxygen saturation in the observation group were (76.64 ± 5.05) mmHg, (10.79 ± 0.53) mmHg, (79.93 ± 5.04) %, respectively, which were significantly higher than those in the control group [(70.32 ± 4.31) mmHg, (9.50 ± 0.62) mmHg, (73.40 ± 4.76) %, t = 5.300, 8.806, 5.245, all P < 0.01]. The incidence of complications in the observation group was significantly lower than that in the control group [9.68% (10/31) vs. 32.26% (8/31), χ2 = 4.769, P < 0.05]. Conclusion:Fluid resuscitation under pulse-indicated continuous cardiac output monitoring has an obvious effect traumatic shock, which can improve vascular endothelial function, inflammatory index and hemodynamic index, and is worthy of popularization and application.

ABSTRACT

Objective:To study the clinical value of induced sputum DKK3 gene methylation in the evaluation of disease condition and prognosis for non-small cell lung cancer (NSCLC).Methods:Eighty NSCLC patients (observation group) and 50 benign lung disease patients (control group) who were treated in Linshu County People′s Hospital of Shandong Province from January 2015 to December 2017 were enrolled. Methylation specific polymerase chain reaction (PCR) was used to detect the induced sputum DKK3 gene methylation. The DKK3 gene methylation rates in different clinicopathological factors were compared.Results:The DKK3 gene methylation rate in observation group was significantly higher than that in control group: 81.3%(65/80) vs. 2.0%(1/50), the difference was statistically significant ( P<0.05). The DKK3 gene was methylated in lung cancer cells, and was unmethylated in normal lung epithelial cells BEAS-2B. The DKK3 gene methylation rates had correlation with pleural effusion, degree of differentiation, tumor diameter, lymph node metastasis, distant metastasis and TNM staging ( P<0.05). The R0 radicalresection, 3-year survival rate and total survival time in patients with DKK3 gene methylated were significantly lower than those in patient with DKK3 gene unmethylated: 53.8%(35/65) vs. 15/15, 28.1% vs. 37.9%, (1.8 ± 0.3) years vs. (2.1 ± 0.6) years, the differences were statistically significant ( P<0.05). Conclusions:The induced sputum DKK3 gene methylation rate in NSCLC patients is significantly higher and is related with prognosis. The induced sputum DKK3 gene methylation may provide basis for evaluating of disease condition and prognosis for NSCLC patients.

ABSTRACT

Objective:To investigate the risk factors for abdominal infection after liver transplantation (LT).Methods:The retrospective case-control study was conducted. The clinical data of 356 patients who underwent LT in the First Affiliated Hospital of Xi′an Jiaotong University from January 2015 to December 2018 were collected. There were 273 males and 83 females, aged from 21 to 67 years, with the median age of 46 years. Observation indications: (1) abdominal infec-tion after LT and distribution of pathogens; (2) analysis of risk factors for abdominal infection after LT; (3) follow-up and survival. Follow-up was performed using outpatient examination and tele-phone interview to detect postoperative 1-year survival rate and cases of death up to June 2020. Measurement data with normal distribution were represented as Mean±SD. Measurement data with skewed distribution were described as M(range). Count data were expressed as absolute numbers or percentages. Univariate analysis was conducted using the chi-square test, t test, Mann-Whitney U test and Fisher exact probability. Multivariate analysis was done using the Logistic regression model. The Kaplan-Meier method was used to calculate sruvival time and survival rates. Log-Rank test was used for survival analysis. Results:(1) Abdominal infection after LT and distribution of pathogens: 63 of 356 recipients had abdominal infection after LT, with the overall incidence of 17.70%(63/356). Of the 63 recipients, 41 cases had abdominal infection within postoperative 2 weeks, 17 cases had multi-drug resistant organism infection. A total of 116 strains of bacteria were isolated from 63 recipients with abdominal infection, 52 of which were gram-negative bacteria, 48 were gram-positive bacteria, 16 were fungi. (2) Analysis of risk factors for abdominal infection after LT: results of univariate analysis showed that preoperative model for end-stage liver disease (MELD) score, preoperative serum albumin, preoperative leukocytes, preoperative prothrombin time, preoperative alanine aminotransferase, preoperative aspartate aminotransferase, operation time, volume of intraoperative blood loss, days of postoperative antibiotic use, postoperative renal failure, postoperative delayed graft function,duration of postoperative intensive care unit stay were related factors for abdominal infection after LT ( Z=-2.456, t=-1.982, Z=-3.193, -2.802, -2.336, -2.276, -2.116, -3.217, χ2=15.807, 10.395, 6.750, Z=-4.468, P<0.05). Liver retransplantaiton and postoperative bile leakage were related factors for abdominal infection after LT ( P<0.05). Results of multivariate analysis showed that preoperative MELD score>20 and liver retransplantation were independent risk factors for abdominal infection after LT ( odds ratio=2.871, 12.875, 95% confidence interval as 1.106-7.448, 1.290-128.521, P<0.05). (3) Follow-up and survival: 356 recipients were followed up for 1-66 months, with a median follow-up time of 32 months. The postoperative 1-year overall survival rate of 63 recipients with abdominal infection and 293 recipients without abdominal infection were 84.60% and 97.03%, respectively, showing a significant difference ( χ2=11.660, P<0.05). During the follow-up, 58 recipients died. Conclusion:Preoperative MELD score>20 and liver retransplantation are independent risk factors for abdominal infection after LT.

ABSTRACT

Objective:To investigate the diagnosis and treatment of hepatic artery thrombosis (HAT) after adult orthotopic liver transplantation.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 411 patients who underwent adult orthotopic liver transplantation in the First Affiliated Hospital of Xi ′an Jiaotong University from December 2011 to July 2018 were collected. There were 328 males and 83 females, aged from 21 to 66 years, with a median age of 46 years. Observation indicators: (1) incidence of HAT and its clinical characteristics; (2) diagnosis of HAT; (3) treatment of HAT; (4) follow-up. Follow-up using outpatient service, telephone interview or WeChat group communication was conducted to detect the incidence of biliary stricture and survival of patients up to August 2018. Measurement data with normal distribution were represented as Mean± SD, measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers or percentages. Survival rate was estimated using the Kaplan-Meier method. Results:(1) Incidence of HAT and its clinical characteristics: 11 of 411 patients had HAT after orthotopic liver transplantation with the incidence of 2.68%(11/411), including 10 males and 1 female, aged 44 years(range, 22-63 years). The time to occurrence of postoperative HAT was 4 days(range, 1-15 days). The etiologies of 11 patients included 6 cases of hepatitis B virus-related cirrhosis, 1 case of hapatitis related cirrhosis, 1 case of hepato-cellular carcinoma, 1 case of liver cirrhosis, 1 case of alcoholic hepatitis related cirrhosis, 1 case of wilson disease. All the 11 patients were ABO compatible. The cold ischemic time and warm ischemic time of donor liver were (316±89)minutes and (13±4)minutes, respectively. Type Ⅰ arterial anasto-mosis was conducted in 11 patients. The clinical manifestations included asymptomatic type in 10 patients and sepsis type in 1 patient. (2) Diagnosis of HAT: all the 11 patients were confirmed with HAT by endovascular angiography, including 7 cases showed no arterial flow under Color Doppler ultrasound, and contrast-enhanced ultrasound indicated HAT. Two patients showed increased hepatic artery resistance index under Color Doppler ultrasound, and contrast-enhanced ultrasound indicated 1 case of HAT and 1 case of anastomotic stenosis. One patient showed slow velocity of hepatic artery blood flow and low resistance index under color Doppler ultrasound, and contrast-enhanced ultrasound indicated HAT. One patient showed slight blood flow signals under Color Doppler ultrasound, and contrast-enhanced ultrasound indicated HAT. (3) Treatment of HAT: 11 patients received endovascular therapy. Six patients had HAT completely disappeared after thrombolytic therapy, 5 patients with residual thrombosis continued thrombolytic therapy with microcatheter urokinase. Six patients with complications were improved after symptomatic treatment. HAT completely disappeared after (6.7±2.6)days of treatment and the clinical success rate was 11/11. (4) Follow-up: 11 patients were followed up for 19-1 722 days, with a median follow-up time of 46 days. During the follow-up, 4 patients had biliary stricture and underwent stent implantation. Nine patients survived with 1-, 3-, 5-year overall survival rates of 75%, 75%, 75%, and 2 patients died.Conclusions:The incidence of HAT after adult orthotopic liver transplantation is low and clinical manifestations are atypical. Contrast enhanced ultrasound can improve diagnosis of suspected thrombosis. Endovascular therapy is safe and effective, which can significantly improve the blood flow of hepatic artery.

ABSTRACT

Isopentenyl diphosphate isomerase (IDI) is a key enzyme in the regulation of triterpenes biosynthesis and plays an important role in ginsenoside biosynthesis. In this study, two IDI genes, PvfIDI1 (GenBank No. MZ736417) and PvfIDI2 (GenBank No. MZ736418) were cloned from Panax vietnamensis var. fuscidiscus. The open reading frame of both PvfIDI1 and PvfIDI2 was 924 bp encoding 307 amino acids. The molecular weights of PvfIDI1 and PvfIDI2 were 34.84 kDa and 34.66 kDa, respectively, with theoretical pIs of 6.01 and 5.66. Bioinformatic analysis indicated that PvfIDI1 and PvfIDI2 contained two conserved sequences: TNTCCSHPL and WGEHELDY. Phylogenetic analysis showed that PvfIDI1 and PvfIDI2 were closely related to Panax notoginseng IDI. Expression analysis showed that both PvfIDI1 and PvfIDI2 genes are expressed in root, rhizome, stem and leaf of P. vietnamensis var. fuscidiscus. However, PvfIDI1 is highly expressed in the rhizome and PvfIDI2 is highly expressed in the stem. PvfIDI1 and PvfIDI2 recombinant proteins were expressed in E. coli; a functional coloration experiment showed that PvfIDI1 and PvfIDI2 could promote the accumulation of lycopene, indicating that both PvfIDI1 and PvfIDI2 encode functional IDI enzymes. The cloning and functional studies on PvfIDI1 and PvfIDI2 provide a foundation for the further study of IDI and the regulation of ginsenoside biosynthesis in P. vietnamensis var. fuscidiscus.

ABSTRACT

Objective To study the impact of brief intervention on HPV cognition of medical students in Xinjiang, and to provide a reference for the development of HPV related education in medical students. Methods Sudents from 20 classes of a medical university in Xinjiang were randomly selected. The first 10 classes were enrolled into group 1, which was a self-controlled study group evaluating the effect before and after intervention. The other 10 classes were included in group 2, in which students in each class were randomly divided into control group (filling in questionnaires before the intervention) and intervention group (filling in questionnaires after the intervention). Medical students were given a 10 minutes presentation on the intervention of HPV by trained personnel. Results (1) For HPV related knowledge, the difference in the awareness rates between the two groups before and after intervention was statistically significant (P < 0.001), and the awareness rate after intervention was higher than that before intervention. Before the intervention, the awareness rates of medical students in group 1 and group 2 were 18.67% and 17.71%, respectively, which increased to 66.75% and 52.85% after the intervention (P<0.01). (2) Regarding HPV-related attitudes and behavioral content, the differences in the response results of the two groups of students before and after the intervention were statistically significant (P<0.05), showing a more positive state after the intervention. Before the intervention, there were 86.19% and 88.02% of the students in group 1 and group 2 willing to publicize HPV-related knowledge to their relatives and friends, and the numbers increased to 94.12% and 94.82%, respectively, after the intervention (P < 0.05). Conclusion Both self-controlled and parallel-controlled studies demonstrated that brief interventions improved medical students' awareness of HPV.

ABSTRACT

Breast cancer is a malignant tumor with a variety of complex mechanisms. Current researchers generally believe that its cause may be related to living environment, daily mood, heredity, behavior habits, et al, but its specific pathogenesis has not yet been studied clearly. With the rapid increase in the number of breast cancer patients worldwide, the clinical treatment methods in most countries have also been continuously improved. At present, the methods such as surgery, radiotherapy and chemotherapy, immunotherapy, and endocrine therapy are mainly adopted in clinical practice. These methods have increased the survival rate of patients, but still with the possibility of recurrence and metastasis, and there are obvious sequelae. Some postoperative patients also experience psychological pressure and burden, which would greatly affect the quality of life. A large number of experiments and clinical experience have proved that due to its unique advantages, traditional Chinese medicine(TCM) has serially improved its current status in the extensive treatment of breast cancer. No matter in post-operative rehabilitation or in the process of co-radiation and chemotherapy, it has played an increasingly prominent role. TCM can improve human immunity, regulate the body's environment, effectively prevent the recurrence and metastasis of breast cancer, improve postoperative recovery, reduce the complications of radiation treatment and iatrochemistry, expressively improve the quality of life of patients, and prolong the survival time of patients. In recent years, the effectiveness of TCM in the treatment of breast cancer has brought more and more great trust from the patients in TCM, and most patients are willing to actively receive TCM treatment, so the mechanisms and approaches of TCM intervention in the treatment of breast cancer still need further research and exploration by our medical workers. By consulting the latest domestic and foreign literature, we reviewed the research progress on five approaches of TCM intervention in the treatment of breast cancer, including signaling pathways, immunotherapy, endocrine therapy, chemotherapy, and radiotherapy. Signal pathway intervention was explained mainly based on wingless-type MMTV integration site family members(Wnt)signaling pathway , B-cell lymphoma-2 (Bcl-2)-associated X protein(Bax)/Bcl-2/cysteinyl aspartate specific proteinase-3(Caspase-3)signaling pathway, phosphatidylinositol 3-kinase(PI3K)/protein kinase B(PKB/Akt)/mammalian target of rapamycin(mTOR)signaling pathway, a highly conserved signal transduction pathway to regulate cell-cell communication(Notch)signaling pathway, mitogen-activated proteinkinase (MAPK) signaling pathway, etc. This article aims to provide reference for the treatment of breast cancer by Chinese medicine.

ABSTRACT

Objective:To investigate the effect of Huoxue Jiedu Runzao prescription on the morphology, apoptosis, and function of submandibular gland in the mouse model of Sjögren's syndrome (SS) and its functioning mechanism, we analyzed the expression of the apoptosis inhibitor Survivin in the submandibular gland cells of SS mice. Method:Female BALB/c57 mice were selected as the normal group. The naive non-obese diabetic (NOD/Ltj) female mice were selected as the SS model, which were randomly assigned into the model group, Paeoniae Radix Alba total glucosides capsule (0.234 g·kg<sup>-1</sup>) group, and low-, medium-, and high-dose (15.6, 31.2, 62.4 g·kg<sup>-1</sup>, respectively) Huoxue Jiedu Runzao prescription groups. Each group had 15 mice. The morphological and functional changes of submandibular gland and the Survivin expression were observed and measured after 8 weeks of drug intervention. Survivin expression was determined by immunohistochemistry (IHC), Western blot, and reverse transcription-polymerase chain reaction (RT-PCR). Result:Compared with normal group, salivary flow and submandibular gland index in model group were significantly decreased (<italic>P</italic><0.01), and histopathological score of submandibular gland was significantly increased (<italic>P</italic><0.01). Western blot showed that Survivin protein expression was significantly decreased (<italic>P</italic><0.05). IHC showed that, Survivin mRNA expression was significantly decreased (<italic>P</italic><0.01), and RT-PCR results showed that Survivin mRNA expression was significantly decreased (<italic>P</italic><0.01). Compared with model group, salivary flow and submandibular gland index of mice in Huoxue Jiudu Runzao prescription groups and Paeoniae Radix Alba total glucosides capsules groups were significantly increased (<italic>P</italic><0.05), histopathological score of submandibular gland was significantly decreased (<italic>P</italic><0.05), IHC results showed that Survivin expression was significantly increased (<italic>P</italic><0.01). Western blot and RT-PCR results showed that Survivin protein and mRNA expression of Huoxue Jiudu Runzao prescription high-dose group and Paeoniae Radix Alba total glucosides capsule group were significantly increased (<italic>P</italic><0.05). Conclusion:Huoxue Jiedu Runzao prescription can improve the secretion function of submandibular acinus, increase the submandibular gland index, and saliva secretion of SS mice by up-regulating survivin in submandibular gland cells of SS mice.
