RESUMEN
Objective:To analyze the influencing factors for efficacy of microvascular decompression (MVD) in primary trigeminal neuralgia (PTN).Methods:A retrospective study was performed. Clinical data of 178 patients with PTN underwent MVD at Department of Neurosurgery, Affiliated Hospital Affiliated to Nantong University from January 2018 to April 2022 were collected. Efficacy was evaluated according to Brisman's criteria. Differences of MVD efficacy in patients with different clinical characteristics or different neurovascular characteristics were compared. Multivariate Logistic regression was used to analyze the independent influencing factors for MVD efficacy.Results:All patients were followed up for about 2 years; at the last follow-up, 164 patients (92.13%) had good postoperative efficacy (130 were cured, 28 were obvious improved, and 6 were improved); 14 patients (7.87%) had poor postoperative efficacy (10 were ineffective and 4 were relapsed). No significant difference in surgical efficacy was noted among patients with different gender, age, left/right lateral pain, disease courses or pain degrees ( P>0.05). Patients with different contact degrees between the trigeminal nerve and blood vessels, different distances between the trigeminal nerve and blood vessels, and different curvature degrees of the posterior trigeminal nerve had significantly different surgical efficacy ( P<0.05). Multivariate Logistic regression indicated that contact degrees between the trigeminal nerve and blood vessels ( OR=0.233, 95% CI: 0.080-0.675, P=0.007), distances between the trigeminal nerve and blood vessels ( OR=6.991, 95% CI: 3.261-14.984, P=0.000), and curvature degrees of the posterior trigeminal nerve ( OR=0.351, 95% CI: 0.158-0.776, P<0.001) were independent influencing factors for postoperative outcomes. Conclusion:The postoperative efficacy is good in patients with slight contact between the trigeminal nerve and blood vessels, with distance between the trigeminal nerve and blood vessels greater than 1×time median width of the trigeminal nerve (WTN), or with hypotenuse height of the arced trigeminal nerve less than 1/2 WTN.

Objective To construct a training program for retuming to work after delivery based on Morrison's job adaptation theory in operating room nurses and to explore its application effect.Methods On the basis of literature research and Delphi expert consultation method,a training program of postpartum return of operating room nurses was constructed.From August 2021 to December 2022,the preliminary application of this research program was carried out,with 6 cases in an experimental group and 5 cases in a control group.The differences between the 2 groups were compared by Job Adaptation Scale,Psychological Resilience Scale and satisfaction evaluation,and the application effect was evaluated.Results After 2 rounds of correspondence,a training program for postpartum return of operating room nurses was formed,which included 4 first-level indicators(role adaptation,task adaptation,environment adaptation and cultural adaptation),and 32 second-level indicators.The authority coefficients of the 2 rounds of correspondence consultation were 0.908 and 0.917,and the Kendall W coefficients were 0.224 and 0.206,respectively(both P＜0.001).The preliminary application results showed that there were statistically significant differences in job adaptation and satisfaction evaluation between the 2 groups(both P＜0.05).There was no significant difference in psychological resilience score between groups(P＞0.05).Conclusion The postpartum retum training program for operating room nurses established in this study is scientific and practical to a certain extent.In the future,samples can be expanded and multi-center studies can be carried out to further test the practicability and effectiveness of the program.
RESUMEN
Objective:To investigate the clinical value of left ventricular shape index (SI) and eccentricity index (EI) in evaluating left ventricular remodeling.Methods:A retrospective analysis was performed on 324 patients (264 males, 60 females, age (62.5±11.8) years) diagnosed with myocardial infarction (MI) and 113 healthy controls (HC; 47 males, 66 females, age (57.8±10.7) years) who received gated myocardial perfusion imaging (GMPI) in First Hospital of Shanxi Medical University from January 2016 to September 2020. SI (end-diastolic SI (EDSI), end-systolic SI (ESSI)), EI and left ventricular function parameters (end-diastolic volume (EDV), end-systolic volume (ESV), left ventricular ejection fraction (LVEF), summed motion score (SMS), summed thickening score (STS), peak ejection rate (PER) and peak filling rate (PFR)) were obtained by quantitative gated SPECT (QGS) software. Propensity score (PS) inverse probability of treatment weighting (IPTW) was used to balance the intergroup covariates. The differences and correlations of EDSI, ESSI, EI and left ventricular function parameters between patients in MI group and HC group were analyzed. ROC curve analysis was used to evaluate the values of EDV, EDSI, ESSI and EI alone and in combination in the assessment of left ventricular systolic function impairment. Data were analyzed by independent-sample t test, Pearson correlation and Spearman rank correlation analyses, and Delong test. Results:After IPTW, EDSI and ESSI in MI group ( n=319) were higher than those in HC group ( n=133; EDSI: 0.66±0.09 vs 0.60±0.06; ESSI: 0.59±0.11 vs 0.47±0.07; t values: 8.05, 14.67, both P<0.001), and EI was lower than that in HC group (0.81±0.06 vs 0.85±0.03; t=-8.93, P<0.001). In both groups, there were significant correlations between EDSI and ESSI ( r values: 0.928, 0.873), between EDSI, ESSI and EI ( r values: from -0.831 to -0.641), between EDSI, ESSI and LVEF ( r values: from -0.627 to -0.201), between ESSI and EDV, ESV and SMS ( rs values: 0.336-0.584), between ESSI and -PER, PFR ( rs values: from -0.406 to -0.402, r values: from -0.352 to -0.325) (all P<0.01). ROC curve analysis showed that EDV (AUC: 0.895) and ESSI (AUC: 0.839) had the highest efficacy in evaluating left ventricular systolic function impairment in MI group and HC group, respectively. EDV-EDSI-ESSI-(1-EI) had higher efficacy in the assessment of impaired left ventricular systolic function in MI group (AUC: 0.956), which was higher than that of EDV or EDV-EDSI or EDV-ESSI or EDV-(1-EI) ( z values: from -2.64 to -2.18, P values: 0.008-0.029); EDV-EDSI-ESSI-(1-EI) also had high efficacy in HC group (AUC: 0.911), which was higher than that of EDV or EDV-EDSI or EDV-(1-EI) ( z values: from -2.60 to -2.43, P values: 0.009-0.015). Conclusions:In MI patients, the increase of SI and the decrease of EI indicate the increase of left ventricular sphericity and the aggravation of left ventricular remodeling. SI and EI have certain clinical application values in evaluating left ventricular morphology, predicting left ventricular remodeling and left ventricular systolic function impairment.
RESUMEN
Objective: To investigate the effects of duration, temperature and shake on paraquat (PQ) concentration in the blood of PQ-exposed rats during the specinen preservation and transportation. Methods: In March 2021, 60 SD male rats of Specific Pathogen Free class were randomly divided into low-dose group (10 mg/kg PQ) and high-dose group (80 mg/kg PQ). Each group was divided into 5 subgroups (normal temperature group, cold storage group, 37 ℃ storage group, shaking on normal temperature group and shaking on 37 ℃ group), six rats in each subgroup. The rats were given intraperitoneal injection of PQ, 1 h after exposure, the blood samples were obtained by cardiac extraction. After different interventions, the concentrations of PQ were detected and compared before and after the intervention in each subgroup. Results: In the shaking on 37 ℃ group, the results of PQ concentrations in PQ-exposed rats were significantly lower than those before the intervention (P<0.05). In the other subgroups, the results were not significantly different compared with before intervention (P>0.05) . Conclusion: The concentration of PQ in the blood of rats exposed to PQ was decreased by shaking for 4 hours at 37 ℃.

To explore the allergen sensitization status of patients with respiratory allergic diseases in Shanxi Province, and to provide a basis for the diagnosis, treatment and prevention of allergic diseases. It is a cross-sectional study, a total of 1 680 patients with allergic rhinitis and/or asthma diagnosed at the Department of Allergic Reaction of Shanxi Bethune Hospital from July 2021 to June 2023 who underwent allergen sIgE testing and/or skin prick test were retrospectively enrolled.There were 772 males and 908 females.The age range was 3 to 88 years. The median age was 35 years.There were 108 cases in the child group (≤12 years old), 102 cases in the adolescent group (13-17 years old), 819 cases in the youth group (18-40 years old), 498 cases in the middle-aged group (41-65 years old), and 153 cases in the elderly group (>65 years old). There were 333 cases in the allergic rhinitis group, 827 cases in the allergic asthma group, and 520 cases in the allergic rhinitis with asthma group. There were 1 254 urban patients and 426 rural patients.There were 253 cases in the northern Shanxi region, 1 195 cases in the central Shanxi region, and 232 cases in the southern Shanxi region. Statistical analyses were performed using the χ 2 test or Fisher's exact probability method to compare the differences in allergen sIgE positivity rates by sex, age, disease, living environment, and geography. The results showed that 1 027 patients (61.1%) were positive for at least one allergen sIgE, with Artemisia having the highest rate of positivity (603/1 680, 35.9%), followed by ragweed (302/1 680, 18.0%) and dust mite combinations (245/1 680, 14.6%). The number of individuals with single-allergen sIgE positivity was 357 (357/1 027, 34.8%), with the highest number of single-allergen sIgE positive results associated with Artemisia (114/357, 31.9%). The number of multiple-allergen sIgE positive results was 670 cases (670/1 027, 65.2%), with the highest number of patients having 2 allergen sIgE positive results (243/670, 36.3%). The overall positivity rate for allergen sIgE was significantly higher among males than among females (65.7% vs. 57.3%, χ2=12.405, P<0.001). Overall positivity for inhalant allergen sIgE was higher in the child and adolescent groups (88.0% vs. 88.2% vs. 59.8% vs. 40.2% vs. 19.0%, χ2=223.372, P<0.001), and food allergen sIgE positivity was highest in the child group (54.6% vs. 36.3% vs. 26.0% vs. 18.9% vs. 21.6%,χ2=66.383,P<0.001). The sIgE positivity rate of inhalant allergens was significantly higher in the allergic rhinitis group and the allergic rhinitis with asthma group than in the allergic asthma group, except for cockroaches and molds (P<0.05). The overall positive rate of allergen sIgE was significantly higher among urban patients than among rural patients (66.2% vs. 46.2%, χ2=53.230, P<0.001). The difference in the overall positive rate of allergen sIgE among patients from different regions was not statistically significant (56.1% vs. 62.0% vs. 62.1%, χ2=3.140, P=0.208). The sIgE positivity of dust mite combinations was significantly higher in the central Shanxi region and the southern Shanxi region than in the northern Shanxi region (15.5% vs. 18.1% vs. 7.1%,χ2=14.411, P=0.001). In conclusion, artemisia was the most important sensitizer for respiratory allergic diseases in Shanxi Province. The types of allergens and positivity rates were different for different sexes, ages, diseases, living environments, and regions. Therefore, patients with allergic diseases should be tested for allergens to help with the diagnosis, treatment and prevention of allergic diseases.

Objective:To investigate the application value of carbon nanoparticle tracer in lymph node dissection for Siewert type Ⅱ and Ⅲ adenocarcinoma of esophagogastric junction (AEG).Methods:The retrospective cohort study was conducted. The clinicopathological data of 147 patients with Siewert type Ⅱ and Ⅲ AEG who were admitted to Shengli Petroleum Central Hospital from June 2015 to July 2020 were collected. There were 109 males and 38 females, aged (65±9)years. All the patients underwent laparoscopic-assisted radical resection of AEG via esophageal hiatus. Of 147 patients, 61 cases not injected with carbon nanoparticle tracer preoperatively were allocated into control group and 86 cases injected with carbon nanoparticle tracer preoperatively were allocated into experimental group. Observation indicators: (1) surgical and postoperative situations; (2) influencing factors analysis of No.10 lymph nodes metastasis. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Count data were represented as absolute numbers or percentages, and comparison between groups was analyzed by the chi-square test. Univariate analysis was conducted by statistic methods based on data type, and multivariate analysis was conducted by the Logistic step-wise regression model. Results:(1) Surgical and postoperative situations. Patients of the experimental group and control group completed laparoscopic-assisted radical resection of AEG via esophageal hiatus successfully. There was no significant difference in the operation time, volume of intraoperative blood loss, the total number of lymph node dissection, the number of the first station, the second station and positive lymph nodes between the two groups ( P>0.05). For the experimental group, the black staining rate of lymph nodes was 57.937%(1 365/2 356), the black staining rate of the first station and second station lymph nodes was 77.989%(1 024/1 313) and 43.691%(232/531), the black staining rate of Siewert type Ⅱ and Ⅲ AEG patients was 56.855%(423/744) and 58.437%(942/1 612), respectively. The lymph node metastasis rate was 19.091%(815/4 269) of 147 patients, 18.573%(242/1 303)of Siewert type Ⅱ AEG patients and 19.319%(573/2 966) of Siewert type Ⅲ AEG patients. For Siewert type Ⅱ AEG patients, the metastasis rate of No.1, 2, 3, 4sa, 4sb, 7, 8a, 11p lymph nodes was more than 10%, the metastasis rate of No.4d, 5, 6, 9, 10, 11d, 12a lymph nodes was lower than 10%. For Siewert type Ⅲ AEG patients, the metastasis rate of No.1, 2, 3, 4sa, 4sb, 7, 8a, 10, 11p and lower mediastinal lymph nodes was more than 10%, the metastasis rate of No.4d, 5, 6, 9 11d, 12a and lower mediastinal lymph nodes was lower than 10%. There was no significant difference in the Clavien Dindo classification of postoperative complications between the two groups ( P>0.05). (2) Influencing factors analysis of No.10 lymph nodes metastasis. Results of multivariate analysis showed that tumor T staging and degree of tumor differention was an independent influencing factor for No.10 lymph nodes metastasis ( P<0.05). Conclusions:For Siewert type Ⅱ and Ⅲ AEG patients, the application of carbon nano-partide tracer can not increase the number of lymph node dissection. The second station lymph node dissection should be paid attention for Siewert type Ⅱ AEG. Tumor T staging and degree of tumor differentiation are independent influencing factors for No.10 lymph nodes metastasis.

Objective To investigate the role and underlying mechanism of cathepsin B in myocar-dial injury in mice with diabetic cardiomyopathy(DCM).Methods Twenty 8-week-old male SPF C57BL/6 mice were randomly divided into wild-type(WT)group and WT DCM group,with 10 mice in each group.Another 20 8-week-old male SPF-grade mice with cathepsin B knockout(KO)were randomly and equally assigned to KO group and KO DCM group.HE staining was used to observe morphological changes,Prussian blue staining was employed to detect iron deposition,while immunohistochemical staining with 4-hydroxynonenal(4-HNE)was used to assess lipid peroxidation level in the myocardial tissues.Western blotting was performed to detect the expression of heme oxygenase-1(HO-1),superoxide dismutase 2(SOD2),and nuclear factor E2-related factor 2(Nrf2),while RT-PCR was applied to evaluate the expressions of Nrf-2,HO-1,and phospholipid hydroperoxide glutathione peroxidase 4(GPX4).Results Compared to the WT DCM group,the KO DCM group presented improved cell arrangement in cardiac tissues and sig-nificant reduction in inflammatory cell infiltration.Furthermore,the KO DCM group displayed a significant decrease in iron deposition compared to the WT DCM group.Additionally,the KO DCM group exhibited a significant reduction in 4-HNE expression compared to the WT DCM group.The protein levels of Nrf2,SOD2,and HO-1 were significant increased in the KO DCM group than the WT DCM group(0.68±0.21 vs 0.39±0.13,0.59±0.10 vs 0.28±0.09,1.03±0.10 vs 0.48±0.04,P＜0.05).Moreover,elevated mRNA levels of GPX4,Nrf2 and HO-1 were also observed in the KO DCM group than the WT DCM group(0.65±0.09 vs 0.40±0.10,0.61±0.11 vs 0.34±0.11,0.62±0.12 vs 0.39±0.09,P＜0.05).Conclusion Cathepsin B exacerbates myocardial injury in DCM mice through ferroptosis.
RESUMEN
OBJECTIVES@#To explore the relationship between atherogenic index of plasma (AIP) and childhood asthma.@*METHODS@#This retrospective study included 86 children with asthma admitted to the Changzhou Second People's Hospital Affiliated to Nanjing Medical University from July 2020 to August 2022 as the asthma group and 149 healthy children undergoing physical examination during the same period as the control group. Metabolic parameters including total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and blood glucose, as well as general information of the children such as height, weight, body mass index, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, and feeding history, were collected. Multivariable logistic regression analysis was used to study the relationship between AIP, triglycerides, and high-density lipoprotein cholesterol and asthma. The value of AIP, triglycerides, and high-density lipoprotein cholesterol for predicting asthma was assessed using receiver operating characteristic (ROC) curve analysis.@*RESULTS@#The AIP and triglyceride levels in the asthma group were significantly higher than those in the control group, while high-density lipoprotein cholesterol was significantly lower (P<0.05). However, there was no significant difference in total cholesterol and low-density lipoprotein cholesterol between the two groups (P>0.05). Before and after adjusting for height, weight, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, feeding method, and blood glucose, multivariable logistic regression analysis showed that AIP, triglycerides, and high-density lipoprotein cholesterol were associated with asthma (P<0.05). ROC curve analysis showed that the optimal cutoff value for predicting asthma with AIP was -0.333, with a sensitivity of 80.2%, specificity of 55.0%, positive predictive value of 50.71%, and negative predictive value of 82.85%. The area under the curve (AUC) for AIP in predicting asthma was significantly higher than that for triglycerides (P=0.009), but there was no significant difference in AUC between AIP and high-density lipoprotein cholesterol (P=0.686).@*CONCLUSIONS@#AIP, triglycerides, and high-density lipoprotein cholesterol are all associated with asthma. AIP has a higher value for predicting asthma than triglycerides and comparable value to high-density lipoprotein cholesterol.

OBJECTIVE To investigate whether Renqing Changjue has a protective effect on acute respiratory dis?tress syndrome (ARDS) induced by endotoxin lipopolysaccharide (LPS) in rabbits. METHODS Thirty-six healthy male New Zealand white rabbits were randomly divided into six groups: normal control group, model group, dexamethasone group, Renqing Changjue high, middle and low dose group, with six rabbits in each group. LPS was used to replicate the ARDS model after five consecutive days of gavage. Arterial pressure, respiratory rate and anal temperature blood were recorded for arterial blood gas analysis at 0, 0.5, 1, 2 and 4 h, respectively. At the end of the four-hour experiment, rab?bits were killed by bloodletting, and the lung tissue was quickly removed to determine the cytokines, SOD, MDA and pathological examination of rabbit lung. RESULTS Renqing Changjue can significantly reduce the pathological changes of lung in ARDS model group. The expression of AQP1 and MPO in rabbit lung was significantly decreased by immuno?histochemistry (P<0.05) ,reduce the lung wet/dry weight ratio, increase the ratio of PaO2/FiO2, inhibit the release of inflammatory factors and scavenge free radicals and antioxidant effects. CONCLUSION Renqing Changjue can effec?tively protect rabbits with acute respiratory distress syndrome induced by LPS, and may protect the lung by inhibiting the release of cytokines and anti-oxidation.
RESUMEN
@#BACKGROUND: The study aims to illustrate the clinical characteristics and development of septic shock in intensive care unit (ICU) patients confirmed with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, and to perform a comprehensive analysis of the association between septic shock and clinical outcomes in critically ill patients with coronavirus disease (COVID-19). METHODS: Patients confirmed with SARS-CoV-2 infection, who were admitted to the ICU of the Third People’s Hospital of Shenzhen from January 1 to February 7, 2020, were enrolled. Clinical characteristics and outcomes were compared between patients with and without septic shock. RESULTS: In this study, 35 critically ill patients with COVID-19 were included. Among them, the median age was 64 years (interquartile range [IQR] 59-67 years), and 10 (28.4%) patients were female. The median ICU length of stay was 16 days (IQR 8-23 days). Three (8.6%) patients died during hospitalization. Nine (25.7%) patients developed septic shock in the ICU, and these patients had a significantly higher incidence of organ dysfunction and a worse prognosis than patients without septic shock. CONCLUSIONS: Septic shock is associated with a poor outcome in critically ill COVID-19 patients and is one of the hallmarks of the severity of patients receiving ICU care. A dysregulated immune response, uncontrolled inflammation, and coagulation disorders are strongly associated with the development and progression of COVID-19-related septic shock.

Objective:To explore multidisciplinary team (MDT) for the treatment of hip fracture in the elderly.Methods:A retrospective analysis was done of the 196 elderly patients who had been admitted to Department of Joint Surgery, Beijing Shijitan Hospital from September 2017 to December 2018 for hip fractures. They were divided into 2 groups depending on whether MDT had been applied or not. In the MDT group of 102 patients, there were 43 males and 59 females with an age of 81.9±8.4 years, and 63 femoral neck fractures and 39 intertrochanteric fractures. In the traditional treatment group of 94 patients, there were 37 males and 57 females with an age of 81.3±8.6 years, and 55 femoral neck fractures and 39 intertrochanteric fractures. The 2 groups were compared in terms of complications and mortality during hospitalization, interval from admission to surgery, total hospital stay, and Harris hip scores at 6 months after surgery.Results:There were no statistically significant differences in general data before surgery between the 2 groups, indicating comparability ( P>0.05). Eighty-four patients (89.4%) in the traditional treatment group and 98 patients (96.1%) in the MDT group underwent surgery, showing no significant difference between the groups ( χ2=3.327, P=0.068). In the patients undergoing surgery in the MDT group, the incidences of postoperative delirium [12.2% (12/98)], pulmonary infection [11.2% (11/98)], cardiogenic disease [13.3%(13/98)], electrolyte disturbance[12.2%(12/98)] and deep venous thrombosis of lower extremity [6.1% (6/98)] were significantly lower, the interval from admission to surgery (1.9 d±0.9 d) and total hospital stay (10.2 d±0.9 d) significantly shorter, and Harris hip scores (81.3±6.2) at 6 months after surgery significantly higher than those in the patients undergoing surgery in the traditional treatment group [31.0%(26/84), 22.6% (19/84), 25.0% (21/84), 28.6% (24/84), 16.7%(14/84); 3.1 d±1.6 d and 14.1 d±6.2 d; 75.4±7.8; respectively] (all P<0.05). Conclusion:In the treatment of hip fracture in the elderly, multidisciplinary team is effective in reducing complications during hospitalization, shortening the interval from admission to surgery and total hospital stay, and promoting functional recovery of the hip.
RESUMEN
Objective:To investigate the diagnostic value of microRNA-29b(miR-29b)for left ventricular hypertrophy(LVH)in elderly patients with coronary heart disease(CHD).Methods:From January 2015 to December 2018, 140 elderly patients with CHD admitted in our hospital were enrolled, including 70 CHD patients without LVH(the NLVH group)and 70 CHD patients with LVH(the LVH group). Seventy healthy elderly adults without CHD who underwent heart examination at our hospital during the same period were included as the control group.The interventricular septum thickness(IVSD), left ventricular posterior wall thickness(LVPWD) and the relative expression level of microRNA-29b were detected and compared among the three groups.The correlation of microRNA-29b with IVSD and LVPWD was analyzed, and the diagnostic value of microRNA-29b for LVH in elderly CHD patients was analyzed.Results:There were significant differences in IVSD, LVPWD and the relative expression level of microRNA-29b among the three groups( F=22.838, 22.147 and 114.096, all P=0.000). The IVSD, LVPWD and the relative expression level of microRNA-29b were higher in the LVH group than in the NLVH group( t=3.479, 3.206 and 9.852, all P=0.000)and than in the control group( t=3.904, 3.553 and 10.792, all P=0.000). The relative expression level of microRNA-29b was higher in the NLVH group than in the control group( t=2.306, P=0.420). The receiver-operating characteristics(ROC)curve analysis of microRNA-29b for the diagnosis of LVH in elderly CHD patients showed that the maximum entry point of Youden index was 0.80, the optimal critical value was 3.52, the sensitivity and specificity for the diagnosis of LVH was 91.73% and 88.27%.Pearson correlation analysis showed that the expression level of microRNA-29b was positively correlated with IVSD and LVPWD( r=0.63 and 0.61, P=0.000). Conclusions:The expression level of microRNA-29b is significantly increased in elderly CHD patients with LVH, and positively correlated with IVSD and LVPWD.The expression level of microRNA-29b has high sensitivity and specificity in the diagnosis of LVH in elderly CHD patients.
RESUMEN
Background: The proportion of recurrences after discharge among patients with coronavirus disease 2019 (COVID-19) was reported to be between 9.1% and 31.0%. Little is known about this issue, however, so we performed a meta-analysis to summarize the demographical, clinical, and laboratorial characteristics of non-recurrence and recurrence groups. Methods: Comprehensive searches were conducted using eight electronic databases. Data regarding the demographic, clinical, and laboratorial characteristics of both recurrence and non-recurrence groups were extracted, and quantitative and qualitative analyses were conducted. Results: Ten studies involving 2071 COVID-19 cases were included in this analysis. The proportion of recurrence cases involving patients with COVID-19 was 17.65% (between 12.38% and 25.16%) while older patients were more likely to experience recurrence (weighted mean difference (WMD)=1.67, range between 0.08 and 3.26). The time from discharge to recurrence was 13.38 d (between 12.08 and 14.69 d). Patients were categorized as having moderate severity (odds ratio (OR)=2.69, range between 1.30 and 5.58), while those with clinical symptoms including cough (OR=5.52, range between 3.18 and 9.60), sputum production (OR=5.10, range between 2.60 and 9.97), headache (OR=3.57, range between 1.36 and 9.35), and dizziness (OR=3.17, range between 1.12 and 8.96) were more likely to be associated with recurrence. Patients presenting with bilateral pulmonary infiltration and decreased leucocyte, platelet, and CD4+ T counts were at risk of COVID-19 recurrence (OR=1.71, range between 1.07 and 2.75; WMD=−1.06, range between −1.55 and −0.57, WMD=−40.39, range between −80.20 and −0.48, and WMD=−55.26, range between −105.92 and −4.60, respectively). Conclusions: The main factors associated with the recurrence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) after hospital discharge were older age, moderate severity, bilateral pulmonary infiltration, laboratory findings including decreased leucocytes, platelets, and CD4+ T counts, and clinical symptoms including cough, sputum production, headache, and dizziness. These factors can be considered warning indicators for the recurrence of SARS-CoV-2 and might help the development of specific management strategies.

Schisandra is the mature fruit of Schisandra chinensis(known as "north Schisandra") or S. shenanthera(known as "south Schisandra"). S. chinensis contains a variety of lignans, volatile oils, polysaccharides, organic acids and other chemical constituents; among them, lignans are recognized as the characteristic active components. Clinical studies have found that Schisandra and Schisandra-related products have a better effect in the prevention and treatment of viral hepatitis, drug-induced liver injury, liver cirrhosis, liver failure and other liver diseases. Modern pharmacological studies have demonstrated that Schisandra has a variety of pharmacological activities, such as anti-inflammation, antioxidation, anticancer, regulation of nuclear receptor, antivirus, regulation of cytochrome P450 enzyme, inhibition of liver cell apoptosis and promotion of liver regeneration. This paper reviews the studies about the applications and mechanism of Schisandra in the prevention and treatment of liver diseases, in the expectation of providing guidance for the development of hepatoprotective drugs from Schisandra and the clinical applications of Schisandra-related products.
