Objective:
To investigate the changes of microorganisms and metabolites in joint effusion of patients with Rheumatoid arthritis(RA), Osteoarthritis(OA) and Urarthritis(UA). To provide new ideas for the study of the effect of microbiota on the pathogenesis of arthritis.
Methods:
Joint effusion samples were collected from 20 patients with RA, 20 patients with OA, and 20 patients with UA. 16S rRNA gene sequencing and untargeted ultra-high performance Liquid chromatography-mass spectrometry(LC-MS) were used to explore the differences in microorganisms and metabolites among the three groups. Pearson correlation analysis was used to detect the correlation between effusion microbiota and metabolites.
Results:
There were differences in microbial diversity and microbiota composition among the three groups. Combined with VIP>1 from OPLS-DA andP<0.05 from two-tailed Students t-test, 45 differential metabolites(Between RA and OA groups), 38 differential metabolites(Between UA and OA groups) and 16 differential metabolites(Between RA and UA groups), were identified. GO analysis and KEGG pathway analysis showed that the differential metabolic pathways among the three groups were mainly concentrated in citric acid cycle(TCA cycle), nucleotide metabolism, amino acid metabolism and glycolysis pathway. Correlation analysis of joint effusion microbiota and metabolites suggested that bacteria enriched in the three groups of joint effusion, such asPrevotella,Clostridium ruminosus,Prevotellaceae_UCG-001, were related to many key metabolites such as lysozyme, uric acid, glucose, and L-glutamine.
Conclusion
This study shows that there are a variety of bacterial flora in joint cavity effusion of RA, OA, and UA patients, and the differential metabolites produced by them are involved in the pathogenesis of the three types of arthritis by affecting a variety of metabolic pathways.

BACKGROUND:
Type 2 diabetes mellitus (T2DM) is an independent risk factor for colorectal cancer (CRC), and the patients with CRC and T2DM have worse survival. The human gut microbiota (GM) is linked to the development of CRC and T2DM, respectively. However, the GM characteristics in patients with CRC and T2DM remain unclear.
METHODS:
We performed fecal metagenomic and targeted metabolomics studies on 36 samples from CRC patients with T2DM (DCRC group, n = 12), CRC patients without diabetes (CRC group, n = 12), and healthy controls (Health group, n = 12). We analyzed the fecal microbiomes, characterized the composition and function based on the metagenomics of DCRC patients, and detected the short-chain fatty acids (SCFAs) and bile acids (BAs) levels in all fecal samples. Finally, we performed a correlation analysis of the differential bacteria and metabolites between different groups.
RESULTS:
Compared with the CRC group, LefSe analysis showed that there is a specific GM community in DCRC group, including an increased abundance of Eggerthella , Hungatella , Peptostreptococcus , and Parvimonas , and decreased Butyricicoccus , Lactobacillus , and Paraprevotella . The metabolomics analysis results revealed that the butyric acid level was lower but the deoxycholic acid and 12-keto-lithocholic acid levels were higher in the DCRC group than other groups ( P < 0.05). The correlation analysis showed that the dominant bacterial abundance in the DCRC group ( Parvimonas , Desulfurispora , Sebaldella , and Veillonellales , among others) was negatively correlated with butyric acid, hyodeoxycholic acid, ursodeoxycholic acid, glycochenodeoxycholic acid, chenodeoxycholic acid, cholic acid and glycocholate. However, the abundance of mostly inferior bacteria was positively correlated with these metabolic acid levels, including Faecalibacterium , Thermococci , and Cellulophaga .
CONCLUSIONS
Unique fecal microbiome signatures exist in CRC patients with T2DM compared to those with non-diabetic CRC. Alterations in GM composition and SCFAs and secondary BAs levels may promote CRC development.

OBJECTIVES:
To evaluate myocardial injury in neonates born to pregnant women with pregnancy complicated by severe preeclampsia by myocardial work indices.
METHODS:
A prospective cohort study was performed on 25 preterm infants born to the pregnant women with severe preeclampsia from June 2020 to April 2021 (severe preeclampsia group), and 25 preterm infants born to the pregnant women without severe complications in pregnancy were enrolled as the control group. Echocardiography was performed within 24 hours and at 48-72 hours and 14-28 days after birth to measure conventional parameters. Two-dimensional speckle-tracking echocardiography was performed to construct a noninvasive left ventricular pressure-strain loop based on two-dimensional myocardial strain and left ventricular systolic pressure noninvasively measured, so as to calculate myocardial work indices.
RESULTS:
Compared with the control group, the severe preeclampsia group had significant reductions in left ventricular global work index and global constructive work within 24 hours after birth (P<0.05), a significant reduction in left ventricular global work efficiency and a significant increase in global waste work at 48-72 hours after birth (P<0.05), and a significant reduction in left ventricular global work efficiency at 14-28 days after birth (P<0.05).
CONCLUSIONS
Subclinical myocardial injury persists in the neonatal period in preterm infants born to pregnant women with severe preeclampsia.

BACKGROUND:
Core muscle functional strength training (CMFST) has been reported to reduce injuries to the lower extremity. However, no study has confirmed whether CMFST can reduce the risk of low back pain (LBP).
OBJECTIVE:
This study identified the effects of CMFST on the incidence of LBP in military recruits.
DESIGN, SETTING, PARTICIPANTS AND INTERVENTION:
We performed a prospective, open-label, randomized, controlled study in a population of young healthy male naval recruits from a Chinese basic combat training program. Participants were randomly assigned to either the core group or the control group. In additional to normal basic combat training, recruits in the core group underwent a CMFST program for 12 weeks, while recruits in the control group received no extra training.
MAIN OUTCOME MEASURES:
At the beginning of the study and at the 12th week, the number of participants with LBP was counted, and lumbar muscle endurance was measured. In addition, when participants complained of LBP, they were assessed using the visual analog scale (VAS) and Roland Morris Disability Questionnaire (RMDQ).
RESULTS:
A total of 588 participants were included in the final analysis (295 in the core group and 293 in the control group). The incidence of LBP in the control group was about twice that of the core group over the 12-week study (20.8% vs 10.8%, odds ratio: 2.161-2.159, P < 0.001). The core group had better lumbar muscle endurance at 12 weeks than the control group ([200.80 ± 92.98] s vs [147.00 ± 84.51] s, P < 0.01). There was no significant difference in VAS score between groups, but the core group had a significantly lower RMDQ score at week 12 than the control group (3.33 ± 0.58 vs 5.47 ± 4.41, P < 0.05).
CONCLUSION
This study demonstrated that the CMFST effectively reduced the incidence of LBP, improved lumbar muscle endurance, and relieved the dysfunction of LBP during basic military training.

ObjectiveTo observe the clinical efficacy and safety of Chinese medicinal mixture for dispelling stasis and resolving phlegm combined with western medicine in the treatment of epilepsy combined with cognitive impairment by randomized, double-blind, placebo-controlled, parallel-group trial. MethodA total of 123 inpatients and outpatients with epilepsy complicated with cognitive impairment admitted to the department of neurology at Longhua Hospital from October 2020 to October 2021 were randomly assigned into a control group (62 cases, carbamazepine + placebo) and a treatment group (61 cases, carbamazepine + Quyu Dingxian Zhengtong mixture) by random number table method. In the treatment group, 4 cases were exfoliated and eliminated. In the control group, 3 cases fell off. Finally, 57 cases in the treatment group and 59 cases in the control group were included. The total course of treatment for both groups was 12 weeks. The clinical efficacy, efficacy for traditional Chinese medicine (TCM) syndromes, and incidence of adverse reactions were compared between two groups. The changes of seizure frequency, abnormal rate of electroencephalogram (EEG), cognitive function score, serum homocysteine (HCY), folic acid, and vitamin B12 (B12) were measured and compared before and after treatment. ResultAfter 12 weeks of treatment, the treatment group had higher clinical efficacy [92.98% (53/57) vs 79.66% (47/59), χ2=4.327, P<0.05] and efficacy for TCM syndromes [96.49% (55/57) vs 84.75% (50/59), χ2=4.660, P<0.05] than the control group. The treatment group was superior to the control group in reducing the seizure frequency (Z=-3.938, P<0.01) and improving the Montreal cognitive assessment (MoCA) score (t=4.333, P<0.01) and mini-mental state examination (MMSE) score (t=9.531, P<0.01). The variations in serum HCY, folic acid, and B12 in the treatment group were less than those in the control group (t=-7.233, t=-7.972, t=-6.871, P<0.01). After treatment, the abnormal rate of EEG in the treatment group was lower than that in the control group (χ2=4.437, P<0.05). The incidence of adverse reactions in the treatment group (1.75%, 1/57) was lower than that (13.56%, 8/59) in the control group (corrected χ2=4.116, P<0.05). ConclusionChinese medicinal mixture for dispelling stasis and resolving phlegm in combination with western medicine had better efficacy and safety than western medicine alone in the treatment of epilepsy complicated with cognitive impairment. Specifically, the combination outperformed western medicine alone in terms of clinical efficacy, efficacy for TCM syndromes, reduction in seizure frequency, abnormal rate of EEG, adverse reactions, improvement of cognitive function, and variations in serum folic acid, B12, and HCY values. Chinese medicinal mixture for dispelling stasis and resolving phlegm may improve the clinical efficacy and safety by changing the metabolism of folic acid, B12, and HCY in serum of the patients with epilepsy complicated with cognitive impairment.

Objective:To examine the survival rates and clinical characteristics of people with newly discovered non-M 3 acute myeloid leukemia (AML) who carry the ASXL1 gene mutation. Methods:From January 2016 to April 2021, the clinical information of patients with newly diagnosed non-M 3 AML at Shandong University's Qilu Hospital was retrospectively examined, and their clinical characteristics and survival were compared and analyzed. Gene mutation was detected by next-generation sequencing. Results:① The study included 256 AML patients who were initially diagnosed and had complete data, including 47 cases of ASXL1 gene mutation-positive (ASXL1 +) patients and 209 cases of ASXL1 gene mutation-negative (ASXL1 -) patients. All patients were divided into three groups: elderly (≥60 years old, n=92) , middle-aged (45-59 years old, n=92) , and young (≤44 years old, n=72) . ②WBC, and age were higher in patients with ASXL1 mutations compared to ASXL1 - patients, while complete response after the first round of treatment (CR 1) was lower ( P<0.05) . In the elderly group, WBC and the proportion of aberrant cells in nuclear cells in ASXL1 + patients were higher than those in ASXL1 - patients ( P<0.05) . In the young group, the WBC of ASXL1 + patients was higher than that of ASXL1 - patients ( z=-2.314, P=0.021) . ③IDH2 mutation and ASXL1 mutation was related ( P=0.018, r=0.34) . In ASXL1 + patients, the proportion of peripheral blasts in the high VAF group (VAF>40% ) was higher than that in the low VAF group (VAF<20% ) , and the proportion of aberrant nuclear cells was higher in the duplication and replacement mutation patients than in the deletion mutation patients ( P<0.05) . ④The overall survival (OS) and progression-free survival (PFS) of ASXL1 + patients were shorter than those of ASXL1 - patients (median, 10 months vs 20 months, 10 months vs 17 months; P<0.05) . The proportion number of aberrant cells in nuclear cells (≥20% ) , complex karyotypes, and TET2 mutation were all independent risk variables that had an impact on the prognosis of ASXL1 + patients, according to multivariate analysis ( P<0.05) . Conclusion:ASXL1-mutated non-M 3 AML patients have higher WBC in peripheral blood, a higher proportion of aberrant cells in nuclear cells, lower CR 1 rate, and shorter OS and PFS. Additionally, a poor prognosis is linked to higher VAF, duplication, and substitution mutations in the ASXL1 gene, as well as the high proportion of aberrant cells in nuclear cells, complex karyotype, and TET2 mutation.

Objective:To explore the effect of precision nursing based on evidence-based concept in the perioperative period of patients with total knee arthroplasty (TKA) .Methods:From January 2018 to December 2020, 200 TKA patients admitted to the First Affiliated Hospital of Zhengzhou University were selected as the study subject by convenience sampling. The patients were divided into the control group and the observation group according to simple random sampling with 100 cases in each group. The control group adopted routine nursing, while the observation group conducted precise nursing based on evidence-based concept on the basis of the control group. The incidence of postoperative complications and knee function between the two groups were compared.Results:The incidence of complications in the observation group was lower than that in the control group, with a statistically significant difference ( P<0.05) . At one, three and six months after operation, the knee function score of New York Hospital for Special Surgery (HSS) in both groups showed an upward trend. The HSS scores of the observation group at one, three, six months after operation were higher than those of the control group, and the difference was statistically significant ( P<0.01) . Conclusions:The precision nursing based on the evidence-based concept has a definite effect in the perioperative nursing of patients with TKA, which can reduce complications and improve the knee function.

BACKGROUND:
The basis of individualized treatment should be individualized mortality risk predictive information. The present study aimed to develop an online individual mortality risk predictive tool for acute-on-chronic liver failure (ACLF) patients based on a random survival forest (RSF) algorithm.
METHODS:
The current study retrospectively enrolled ACLF patients from the Department of Infectious Diseases of The First People's Hospital of Foshan, Shunde Hospital of Southern Medical University, and Jiangmen Central Hospital. Two hundred seventy-six consecutive ACLF patients were included in the present study as a model cohort (n = 276). Then the current study constructed a validation cohort by drawing patients from the model dataset based on the resampling method (n = 276). The RSF algorithm was used to develop an individual prognostic model for ACLF patients. The Brier score was used to evaluate the diagnostic accuracy of prognostic models. The weighted mean rank estimation method was used to compare the differences between the areas under the time-dependent ROC curves (AUROCs) of prognostic models.
RESULTS:
Multivariate Cox regression identified hepatic encephalopathy (HE), age, serum sodium level, acute kidney injury (AKI), red cell distribution width (RDW), and international normalization index (INR) as independent risk factors for ACLF patients. A simplified RSF model was developed based on these previous risk factors. The AUROCs for predicting 3-, 6-, and 12-month mortality were 0.916, 0.916, and 0.905 for the RSF model and 0.872, 0.866, and 0.848 for the Cox model in the model cohort, respectively. The Brier scores were 0.119, 0.119, and 0.128 for the RSF model and 0.138, 0.146, and 0.156 for the Cox model, respectively. The nonparametric comparison suggested that the RSF model was superior to the Cox model for predicting the prognosis of ACLF patients.
CONCLUSIONS
The current study developed a novel online individual mortality risk predictive tool that could predict individual mortality risk predictive curves for individual patients. Additionally, the current online individual mortality risk predictive tool could further provide predicted mortality percentages and 95% confidence intervals at user-defined time points.
