Characteristics and driving forces of the soil microbial community during 35 years of natural restoration in abandoned areas of the Daxin manganese mine, China.

The restoration of mining wastelands, particularly in karst regions contaminated by heavy metals, is an environmental challenge in need of urgent attention. Soil microbes play a vital role in nutrient cycling and ecosystem recovery, yet the long-term evolution of soil microbial communities in such settings remains poorly understood. This study explored the dynamics and influencing factors of soil microbial communities during 35 years of natural restoration in abandoned manganese (Mn) mine areas in Guangxi Province, China. The results revealed that the concentrations of Mn, Cd, Zn, and Cu were significantly (p < 0.05) reduced by 80.4-85.3%, 55.3-70.0%, 21.0-38.1%, and 29.4-49.4%, respectively, in the mid-late restoration periods (R19 and R35) compared with R1. The α diversities of the bacterial and fungal communities significantly increased in the middle-late restoration periods (R19 and R35), indicating increased microbial diversity as restoration progressed. The bacterial community structure exhibited more pronounced changes than did the fungal community structure, with significant shifts observed in dominant phyla such as Proteobacteria, Actinobacteria, Acidobacteriota, and Ascomycota. Notably, the relative abundances of Rhizobiales, Burkholderiales, and Hypocreales increased gradually with succession. Co-occurrence network analysis revealed that bacterial interactions became stronger over time, whereas interactions between bacteria and fungi weakened. Mantel tests and partial least squares path modeling (PLS‒PM) identified soil pH, heavy metals (Mn, Cd, Zn, and Cu), and nutrients (SOM and TN) as key drivers shaping the microbial community composition. These factors were more strongly correlated with bacterial communities than with fungal communities, underscoring the different responses of microbial groups to environmental changes during natural restoration. These findings enhance our understanding of the ecological processes governing microbial community succession in heavy metal-contaminated soils undergoing natural restoration.

[Auricular pressure beans combined with Compound Tung-Leaf Burn Oil relieve perioperative anxiety and pain in patients undergoing circumcision].

OBJECTIVE: To observe the effect of auricular pressure beans (APN) combined with Compound Tung-Leaf Burn Oil (CTBO) on perioperative anxiety and pain in patients undergoing circumcision. METHODS: This study included 100 patients undergoing circumcision with the disposable circumcision anastomosis stapler in our hospital from August 2023 to November 2023, of whom 50 received routine circumcision nursing care (the control group) and other 50 APN combined with compound CTBO in addition (the observation group). We compared between the two groups the anxiety scores before any intervention, 30 minutes before and 24 hours and 10 days after operation, the pain scores 24 hours postoperatively and at the first change of wound dressing, the frequency of 3-day postoperative sleep awakenings, the incidence of complications, and the satisfaction of the patients. RESULTS: Totally, 94 patients completed the study, 46 in the observation and 48 in the control group. The anxiety scores exhibited no statistically significant difference between the two groups of patients before any intervention (P > 0.05), but were markedly lower in the observation than in the control group at 30 minutes before and 24 hours and 10 days after surgery (P<0.05), and so were the pain scores 24 hours after surgery and at the first change of wound dressing (P<0.05), and the frequency of 3-day postoperative sleep awakenings (P<0.05). The satisfaction rate of the patients was remarkably higher (P<0.05) while the incidence of complications significantly lower in the observation group than in the control (P<0.05). CONCLUSION: Auricular pressure beans combined with Compound Tung-Leaf Burn Oil can effectively alleviate perioperative anxiety, reduce postoperative pain and improve satisfaction of the patients undergoing circumcision.

Status of traditional Chinese medicine healthcare services in nursing homes across China.

This study aimed to elucidate the status of traditional Chinese medicine (TCM) healthcare services provided in nursing homes across China. We investigated 484 nursing homes using self-compiled questionnaires with a convenient sampling method. Chi-squared and Wilcoxon rank-sum tests were used for univariate analysis and binary logistic regression for multi-factor analysis. Of the 443 nursing homes finally included, 215 (48.5%) provided TCM healthcare services. Nursing home leaders majored in integrated TCM and Western medicine, leaders with a better understanding of TCM and government policies, nursing homes charging over 5,000 CNY/month, and those with ≥500 beds were more likely to provide improved TCM healthcare services. Massage, moxibustion, cupping or scraping, plaster therapy, decocting pieces, and acupuncture were the most prevalent and popular TCM services. Lack of professionals, financial investment, and policy support were the most common factors limiting the provision of TCM healthcare services in Chinese nursing homes.

Overexpression of Kin of IRRE-Like Protein 1 (KIRREL) in Gastric Cancer and Its Clinical Prognostic Significance.

BACKGROUND The aim of this study was to examine the expression level of IRRE-like protein 1 (KIRREL) in gastric cancer (GC) and to explore its prognostic significance. MATERIAL AND METHODS Bioinformatics methods were used to predict the differential expression levels of KIRREL mRNA in GC and normal gastric tissues by mining cancer-related databases (TCGA and Oncomine). Immunohistochemistry was done to verify the KIRREL protein expression levels in 71 cases of GC tissues combined with matched normal tissues. The relationship between clinicopathologic parameters and KIRREL differential expression levels in GC was investigated by the chi-square test. Kaplan-Meier univariate and Cox multivariate survival analyses were performed to explore the prognostic significance of KIRREL expression in GC patients. RESULTS TCGA and GEO data analyses showed that KIRREL mRNA expression level was remarkably higher in GC than that in normal gastric tissues (both P<0.05). KIRREL mRNA levels were dramatically increased from stage I to stage IV (P=0.037). Immunohistochemical results showed that the high positive rate of KIRREL staining in GC was 61.97% (44/71). Moreover, GC patients with KIRREL mRNA or protein high levels had significantly shorter overall survival times than those with KIRREL mRNA or low protein levels (All P<0.05). Additionally, Cox multivariate survival analysis revealed that KIRREL differential expression levels (low vs. high) were the only independent parameter predicting the prognosis of GC patients (P=0.000). CONCLUSIONS KIRREL was overexpressed in GC and the overexpression of KIRREL could serve as an independent predictor of poor prognosis in GC patients.

Promoter methylation of DAPK gene may contribute to the pathogenesis of nonsmall cell lung cancer: a meta-analysis.

We performed a meta-analysis of cohort studies to determine whether promoter methylation of the death-associated protein kinase (DAPK) gene contributes to the pathogenesis of nonsmall cell lung cancer (NSCLC). A range of electronic databases were searched: MEDLINE (1966 ∼ 2013), the Cochrane Library Database (Issue 12, 2013), EMBASE (1980 ∼ 2013), CINAHL (1982 ∼ 2013), Web of Science (1945 ∼ 2013), and the Chinese Biomedical Database (CBM; 1982 ∼ 2013) without any language restrictions. Meta-analysis was conducted using the STATA 12.0 software. Crude odds ratio (OR) with 95 % confidence interval (95 % CI) was calculated. Our meta-analysis integrated results from 12 clinical cohort studies that met all inclusion criteria with a total of 1,027 NSCLC patients. We observed that the frequency of DAPK gene methylation in cancer tissues were significantly higher than that in the adjacent normal and benign tissues (cancer tissues vs. benign tissues: OR=8.50, 95 % CI=5.88 ∼ 12.28, P<0.001; cancer tissues vs. adjacent tissues: OR=5.95, 95 % CI=4.11 ∼ 8.60, P<0.001; cancer tissues vs. normal tissues: OR=4.75, 95 % CI=3.28 ∼ 6.87, P<0.001; respectively). Subgroup analysis by ethnicity demonstrated that DAPK gene methylation was closely associated with the development and progression of NSCLC among both Asians and Caucasians (all P<0.05). Furthermore, we conducted a subgroup analysis based on sample source and discovered that DAPK gene methylation was implicated in the pathogenesis of NSCLC in both blood and tissue subgroups (all P<0.05). Our results suggest that DAPK promoter methylation may be involved in NSCLC carcinogenesis. Thus, the detection of aberrant DAPK methylation may be helpful in the diagnosis and prognosis of NSCLC.

Analysis of biopsy pathology and risk factors of lymph node metastasis in prostate cancer.

OBJECTIVE: To explore the relationship between biopsy pathology and lymph node metastasis in patients with prostate cancer (PCa), and to identify risk factors of lymph node metastasis (LNM). PATIENTS AND METHODS: Patients diagnosed with prostate cancer were respective screened between Jan 2015 and May 2022. Patients diagnosed PCa via 13-core ultrasound-guided biopsies and underwent radical prostatectomy and lymph node dissection were identified. The clinicopathological characteristics of the patients were recorded. Relationships between LNM and non-LNM were analyzed using chi-square and independent samples t-test. Logistic regression model was fitted to analyze the risk factors of lymph node metastases. RESULTS: Two hundreds and fifteen patients were included, sixty-seven patients had lymph node metastasis. Gleason scores in LNM group were higher than that in non-LNM group (8.5 ± 0.9 VS 7.5 ± 1.5, p < 0.001), positive biopsy in non-LNM group was significantly lower than that in LNM group (p < 0.001), Binary logistic regression analysis indicated number of positive biopsy and number of removed lymph nodes increased the risks of LNM (odds ratio, OR = 1.28, 95% confidence interval, CI = 1.16-1.42, p < 0.001; OR = 1.11, 95% CI = 1.06-1.17, p < 0.001; respectively). Number of positive biopsy in internal gland but not external gland was significant associated with LNM (OR = 1.66, 95% CI = 1.34-2.06, p < 0.001; OR = 1.19, 95% CI = 0.88-1.61, p = 0.262; respectively). The patients with lymph nodes dissection more than 13 were about four times more likely to detect lymph node metastasis than those fewer than 13 (OR = 3.92, 95% CI = 2.10-7.33, p < 0.001). CONCLUSIONS: The risk of lymph node metastasis increased with the number of positive prostate biopsy cores, and tumors in the internal gland were more likely to cause lymph node metastasis. In addition, lymph node metastasis was more likely to be found when the number of lymph nodes dissection was greater than 13.

Clinical implications of serum miR-34a in breast cancer and its predictive value for the efficacy of neoadjuvant chemotherapy.

OBJECTIVES: This study aims to explore the implications of serum miR-34a in breast cancer (BC) and its predictive value for the efficacy of neoadjuvant chemotherapy (NACT). METHODS: A retrospective analysis was performed on 102 female BC patients (research group) admitted to The Second Affiliated Hospital of Anhui Medical University between January 2016 to March 2018 and 102 concurrent female health controls who underwent physical examinations (control group). Serum samples from both groups were subjected to quantitative reverse transcription polymerase chain reaction to measure miR-34a expression. The correlation of miR-34a with BC patients' clinical parameters was analyzed, and the implications of miR-34a for diagnosing BC and predicting NACT efficacy were assessed by receiver operating characteristic curves. Logistic regression analysis was employed to determine whether miR-34a independently influenced treatment effectiveness and patient outcomes. RESULTS: The data showed significantly lower miR-34a levels in the research group than in the control group (P<0.05). The area under the curve (AUC) of miR-34a for differentiating BC was 0.888. In BC patients, miR-34a was strongly correlated with tumor staging and differentiation degree. Following NACT, BC patients showed an evident rise in miR-34a expression, with higher levels in patients with effective treatment compared to those with treatment failure (P<0.05). The AUC values of serum miR-34a in predicting the efficacy of neoadjuvant chemotherapy from FD to SD and from SD to TD were 0.880 and 0.861, respectively (P<0.001). Furthermore, patients with favorable prognosis exhibited markedly higher serum miR-34a expression than those with poor prognosis (P<0.05). The AUC of miR-34a expression for predicting adverse prognosis was 0.825. Decreased miR-34a was identified as an independent risk factor for treatment failure and poor prognosis. CONCLUSIONS: Taken together, serum miR-34a is downregulated in BC and can predict the clinical progression of BC patients and the therapeutic efficacy of NACT.

Dexamethasone inhibits androgen receptor-negative prostate cancer cell proliferation via the GR-FOXO3a-GAS5 axis.

Background: Studies have shown that glucocorticoid receptor (GR) has inconsistent effects on the proliferation of prostate cancer cells, we found dexamethasone inhibited the proliferation of androgen receptor-negative prostate cancer cells, but the underlying mechanisms remain to be illustrated. Methods: GR expression and its prognosis role were analyzed based on the TCGA dataset. Bioinformatic analysis was performed to identify the candidate of GR downstream, which includes FOXO3a. After overexpressing FOXO3a in PC-3 cells, cell counting kit-8 (CCK-8) and migration assays were performed to evaluate cell proliferation and migration ability. Regulation of FOXO3a on GAS5 was also analyzed by JASPAR and PCR. Results: GR had low expression in prostate cancer and predicted poor prognosis. FOXO3a was identified as the downstream of GR to inhibit the proliferation of prostate cancer cells. Moreover, FOXO3a directly induces GAS5 expression, forming the GR-FOXO3a-GAS5 signaling pathway. Conclusion: Our study showed that GR played a role as a tumor suppressor gene in androgen receptor-negative prostate cancer cells via the GR-FOXO3a-GAS5 axis. Our results suggested patients with prostate cancer should be classified and develop a treatment plan according to the expression of AR and GR.

Efficacy and safety of nanoparticle albumin­bound paclitaxel compared with solvent­based paclitaxel in adjuvant therapy for breast cancer: A retrospective study.

The current evidence for the use of nanoparticle albumin-bound paclitaxel (nab-PTX) for adjuvant breast cancer chemotherapy is insufficient. The present study aimed to assess the efficacy and toxicity of nab-PTX in comparison with solvent-based paclitaxel (sb-PTX) in postoperative adjuvant breast cancer treatment. A total of 345 patients were included in the study and separated into nab-PTX (n=289) and sb-PTX (n=56) groups based on the type of taxane used in the adjuvant chemotherapy regimen. The study evaluated the baseline characteristics in both groups and the risk factors for postoperative recurrence of mammary cancer. Furthermore, data concerning disease-free survival (DFS) and adverse effects were obtained and analyzed, and group confounding variables were addressed using 1:2 propensity score matching (PSM). Comparisons before PSM revealed significant differences in baseline characteristics including age, underlying disease, lymph node involvement, vascular invasion, human epidermal growth factor receptor 2 and axillary surgery (P<0.05). Following PSM, there were 90 patients in the nab-PTX group and 56 in the sb-PTX group, with no significant differences in the baseline differences (P>0.05). Before PSM, the 73-month DFS rate was 97.9% in the nab-PTX group compared with 91.1% in the sb-PTX group. However, there were no significant differences between the groups before or after PSM (P=0.15 and P=0.49, respectively). Additionally, Cox regression analysis demonstrated a significantly lower chance of recurrence in patients aged >45 years [hazard ratio (HR), 0.197; 95% confidence interval (CI), 0.052-0.753; P=0.018], whereas underlying disease (HR, 5.352; 95% CI, 1.310-21.854; P=0.019) and lymph node infiltration (HR, 8.930; 95% CI, 1.121-71.161; P=0.039) significantly increased the risk of recurrence. Regarding safety, the sb-PTX group had a significantly greater incidence of anaphylaxis, whereas the nab-PTX group had significantly increased rates of anemia and peripheral neuropathy (P<0.05). In summary, the 73-month DFS rate of the nab-PTX cohort exceeded that of the sb-PTX cohort, but no significant difference was detected between them. Underlying disease, lymph node metastasis and an age of ≤45 years are significant predictors of postoperative recurrence of breast cancer.

Molecular cloning, expression, purification and characterization of thioredoxin from Antarctic sea-ice bacteria Pseudoalteromonas sp. AN178.

Thioredoxin (Trx) is a highly conserved and multi-functional protein that plays a pivotal role in maintaining the redox state of the cell and in protecting the cell against oxidative stress. Trx gene from Antarctic sea-ice bacteria Pseudoalteromonas sp. AN178 was cloned and expressed as soluble protein in Escherichia coli (designated as PsTrx). Trx gene consisted of an open reading frame of 324-bp nucleotides encoding a protein of 108 amino acids with a calculated molecular mass of 11.88 kDa. The deduced protein included the conserved Cys-Gly-Pro-Cys active-site sequence. After purification by a single step Ni-NTA affinity chromatography, recombinant PsTrx with a high specific activity of 96.67 U/mg was obtained. The purified PsTrx had an optimal temperature and pH of 25 °C and 7.0, respectively, and showed about 55 % of the residual catalytic activity even at 0-10 °C. It had high tolerance to a wide range of NaCl concentrations (0-2 M NaCl) and was stable in the presence of H2O2. This research suggested that PsTrx displayed unique catalytic properties.

Effectiveness of mHealth management with an implantable glucose sensor and a mobile application among Chinese adults with type 2 diabetes.

INTRODUCTION: This study aimed to evaluate the effectiveness of mHealth management with an implantable glucose sensor and a mobile application among patients with type 2 diabetes mellitus (T2DM) in China. METHODS: A randomised controlled trial was carried out to compare the effectiveness of usual health management to mHealth management based on a model that consisted of the network platform, an implantable glucose sensor and a mobile app featuring guidance from general practitioners (GPs) over a four-week period. Patients (N=68) with T2DM were randomly divided into an intervention group and a control group. Before the intervention, there was no difference in body mass index (BMI), fasting blood glucose (FBG), postprandial two-hour blood glucose (2hPG) and glycosylated haemoglobin (HbA1c) between the intervention group and the control group (p>0.05). Patients in the control group received their usual health management, while patients in the intervention group received mHealth management. RESULTS: After health management, the mean BMI, FBG, 2hPG and HbA1c of the intervention group patients were all lower than those of the control group patients (p < 0.05), and the quality of life and self-management of the intervention group patients had significantly improved. DISCUSSION: mHealth management effectively showed significant reductions in BMI, FBG, 2hPG and HbA1c and improved quality of life and self-management among patients, which may be related to real-time feedback from an implantable glucose sensor and guidance from GPs through a mobile app. mHealth management is a very promising way to promote the health management of T2DM in China, and this study provides a point of reference for mHealth management abroad.

Social capital and loneliness among older adults in community dwellings and nursing homes in Zhejiang Province of China.

Background: Loneliness is an important problem afflicting the health of older adults, and has been proven to be associated with social capital. Previous research in China rarely investigated the differences of social capital and loneliness between older adults living in community dwellings and nursing homes. This study aims to examine the status of social capital and loneliness among older adults living in community dwellings and nursing homes, and analyze the relationship between them. Methods: A total of 1,278 older adults were recruited for the study from the cities of Hangzhou, Huzhou, and Lishui in Zhejiang Province of China from July to October 2021 by using multi-stage stratified random sampling. Questionnaires were used to collect data on the participants' sociodemographic characteristics, social capital, and loneliness. Hierarchical multiple regression was used to examine the relationship between social capital and loneliness. The interaction of social capital and institutionalization on loneliness was also explored. Results: Compared with community-dwelling older adults, institutionalized older adults had higher levels of loneliness and lower degrees of social support, social connection, trust, cohesion, and reciprocity. A further analysis of the social capital showed that low levels of social support, trust, and cohesion were related to high levels of loneliness among adults in both community dwellings and nursing homes. Social connection was negatively correlated with loneliness among older adults living in community dwellings. Institutionalization itself demonstrated a strong effect on loneliness. Conclusion: Health-related policies should help older adults gain more social support, trust and cohesion to alleviate their loneliness. This is particularly crucial for older adults living in nursing homes, as they have higher levels of loneliness and lower levels of social capital than noninstitutionalized older adults.

The Effectiveness of a Specialized Nursing Team Intervention in the Unplanned Interruption of Continuous Renal Replacement Therapy.

Background: To explore the application of specialist nursing teams in patients undergoing unplanned interruptions in continuous renal replacement therapy. Methods: Sixty-six patients admitted to the intensive care unit of Jiangsu Province Hospital, China for continuous renal replacement therapy (CRRT) and experienced unplanned interruptions from Aug 2020 to Mar 2021 were enrolled as study subjects. Twenty four patients with conventional care were taken as the control group, and 42 patients in the specialized nursing team were taken as the experimental group. The age, type of disease, and degree of illness of the two groups were statistically processed and the differences were not significant (P>0.05) and were comparable. The control group received routine CRRT care after CRRT rescue, and the experimental group received CRRT care model from a specialized nursing team. Results: Patients in the group with specialized nursing care had 49 instances of CRRT unplanned interruptions, and the routine care group had 79 instances of CRRT unplanned interruptions. The number of unplanned interruptions in the experimental group was less than that of the control group, and the difference was statistically significant (P<0.001). The incidence of complications in the experimental group were lower than that of the control group (P<0.05). The satisfaction and quality of life of nurses in the specialist nursing group were clearly lower than those of the control group, and the difference was statistically significant (P<0.05). Conclusion: Specialist nursing teams could reduce the occurrence of unplanned interruptions in CRRT patients in intensive care and allow patients to receive continuity of care.

Analysis of the Incidence of Euthyroid Sick Syndrome in Comprehensive Intensive Care Units and Related Risk Factors.

Objective: A low concentration of plasma triiodothyronine (T3) indicates euthyroid sick syndrome (ESS), which could be associated with a poor outcome in patients in intensive care units (ICUs). This study evaluated the relationship between ESS and prognostic indicators in patients admitted to an ICU and examined the free T3 (FT3) cut-off points that could be associated with 28-day mortality. Methods: This prospective observational study included patients admitted to the ICU of The Third Hospital of Hebei Medical University between February and November 2018. Baseline variables and data on the occurrence of low FT3 were collected. The patients were divided into ESS (FT3 < 3.28 pmol/L) and non-ESS groups. The relationship between ESS and prognostic indicators in patients admitted to the ICU was evaluated, and the FT3 cut-off points that could be associated with 28-day mortality were examined. Results: Out of a total of 305 patients, 118 (38.7%) were in the ESS group. Levels of FT3 (P < 0.001) and FT4 (P = 0.001) were lower, while the 28-day mortality rate (P < 0.001) and hospitalization expenses in the ICU (P = 0.001) were higher in the ESS group. A univariable analysis identified ESS, FT3, free thyroxine (FT4)/FT3, the APACHE II score, the sequential organ failure (SOFA) score, the duration of mechanical ventilation, creatinine (CREA) levels, the oxygenation index (HGB), white blood cells, albumin (ALB) levels, age, and brain natriuretic peptide (BNP) levels as factors associated with 28-day mortality (all P < 0.05). The cut-off value of FT3 for 28-day mortality was 2.88 pmol/L, and the 28-day mortality rate and hospitalization expenses in the ICU were higher in patients with ESS. The syndrome was confirmed to be independently associated with 28-day mortality. Conclusion: This study determined the incidence of ESS in the comprehensive ICU to be 38.7%. APACHE II, SOFA, BNP, APTT, HGB, PLT, CREA, ALB, FT4, SBP, and DBP are closely related to ESS, while BNP, PLT, and ALB are independent risk factors for the syndrome.

Percutaneous vs Laparoscopic Treatment for Simple Renal Cysts: A Meta-analysis.

Objective: To compare the percutaneous and laparoscopic treatment for renal cyst to determine the optimal therapy for patients with renal cyst. Materials and Methods: A systematic search of PubMed, Cochrane Library, Web of Science, and EMBASE databases was conducted for articles published through June 3, 2020, using the preferred reporting items for systematic reviews and meta-analyses guidelines. Results: We found 493 studies from databases, and 6 were considered for the evidence synthesis. A total of 1631 cases were included. Of these patients, 488 cases underwent laparoscopic treatment and 1143 cases underwent percutaneous treatment. Symptomatic and radiologic success were higher for laparoscopic treatment (odds ratio [OR], OR = 3.59, confidence interval [95% CI], 1.45-8.88, p = 0.006; and OR = 7.46, 95% CI 3.99-13.94, p < 0.00001, respectively). Minor or severe complications were similar between the two treatments (OR = 1.54, 95% CI 0.40-5.98, p = 0.53; OR = 3.13, 95% CI 0.03-359.76, p = 0.64, respectively). Conclusion: Laparoscopic treatment for renal cyst was associated with better symptomatic and radiologic success, and its complication was no more than percutaneous treatment.

Standard versus mini-percutaneous nephrolithotomy for renal stones: a meta-analysis.

OBJECTIVES: To compare the standard percutaneous nephrolithotomy and mini-percutaneous nephrolithotomy in order to determine the optimal tract size for patients with renal stones. METHODS: A systematic search of Web of Science, EMBASE, Cochrane Library, and PubMed databases was conducted for articles published through 20 August 2019, reporting on a comparison of the standard percutaneous nephrolithotomy and mini-percutaneous nephrolithotomy using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS: Of 763 studies, 14 were considered for the evidence synthesis. A total of 1980 cases were included. Of these patients, 897 cases underwent standard percutaneous nephrolithotomy, and 1083 cases underwent mini-percutaneous nephrolithotomy. Stone-free rates were 87.6% (786 of 897 patients) for standard percutaneous nephrolithotomy and 87.8% (951 of 1083 patients) for mini-percutaneous nephrolithotomy (p = 0.57). Tract sizes of 30F and 22-26F in standard percutaneous nephrolithotomy group shorten operation time compared with mini-percutaneous nephrolithotomy (p = 0.02; p = 0.004; respectively). Leakage (p = 0.04), bleeding (p = 0.01), blood transfusion (p < 0.00001), and renal pelvis perforation (p = 0.02) were more common in standard percutaneous nephrolithotomy group than in mini-percutaneous nephrolithotomy group. Subgroup analysis showed only blood transfusion for 30F and 22-26F standard percutaneous nephrolithotomy group was more common than mini-percutaneous nephrolithotomy (p < 0.0001, p = 0.005, respectively). CONCLUSIONS: Standard percutaneous nephrolithotomy was associated with higher leakage, bleeding, blood transfusion, and renal pelvis perforation, but had a shorter operation time. Tract size of 30F improved the stone-free rate compared with mini-percutaneous nephrolithotomy, but led to more complications. Tract size of 22-26F was no better than 30F or mini-percutaneous nephrolithotomy.

Analysis of related factors of radiation pneumonia caused by precise radiotherapy of esophageal cancer based on random forest algorithm.

The precise radiotherapy of esophageal cancer may cause different degrees of radiation damage for lung tissues and cause radioactive pneumonia. However, the occurrence of radioactive pneumonia is related to many factors. To further clarify the correlation between the occurrence of radioactive pneumonia and related factors, a random forest model was used to build a risk prediction model for patients with esophageal cancer undergoing radiotherapy. In this study, we retrospectively reviewed 118 patients with esophageal cancer confirmed by pathology in our hospital. The health characteristics and related parameters of all patients were analyzed, and the predictive effect of radiation pneumonia was discussed using the random forest algorithm. After treatment, 71 patients developed radioactive pneumonia (60.17%). In univariate analyses, age, planning target volume length, Karnofsky performance score (KPS), pulmonary emphysema, with or without chemotherapy, and the ratio of planning target volume to planning gross tumor volume (PTV/PGTV) in mediastinum were significantly associated with radioactive pneumonia (P < 0.05 for each comparison). Multivariate analysis revealed that with or without pulmonary emphysema (OR = 7.491, P = 0.001), PTV/PGTV (OR = 0.205, P = 0.007), and KPS (OR = 0.251, P = 0.011) were independent predictors for radiation pneumonia. The results concluded that the analysis of radiation pneumonia-related factors based on the random forest algorithm could build a mathematical prediction model for the easily obtained data. This algorithm also could effectively analyze the risk factors of radiation pneumonia and formulate the appropriate treatment plan for esophageal cancer.

Prognostic value of serum aquaporin-1, aquaporin-3 and galectin-3 for young patients with colon cancer.

BACKGROUND: This study aimed to investigate the long-term prognosis value of serum galectin-3, aquaporin (AQP)-1 and AQP-3 in young patients with colon cancer. METHODS: A total of 100 young patients with colon cancer, 100 cases of benign colon and 100 healthy people were collected. All colon cancer patients were followed up for 42 months. RESULTS: Compared with the benign lesion group and the control group, preoperative serum galectin-3, AQP-1 and AQP-3 concentrations were significantly increased in patients with colon cancer (P < 0.05). The immunohistochemistry scores of galectin-3, AQP-1 and AQP-3 in colon cancer patients were positively correlated with serum galectin-3, AQP-1 and AQP-3 concentrations (P < 0.05). Serum galectin-3, AQP-1 and AQP-3 concentrations were positively correlated with TNM staging (galectin-3: rPearson = 0.502, P < 0.001; AQP-1: rPearson = 0.415, P < 0.001; AQP-3: rPearson = 0.454, P < 0.001) and differentiation (galectin-3: rPearson = 0.377, P = 0.004; AQP-1: rPearson = 0.411, P = 0.001; AQP-3: rPearson = 0.483, P < 0.001). Receiver operator characteristic curve (ROC) analysis showed that the area under ROC curve (AUC) of the combination of galectin-3, AQP-1 and AQP-3 in distinguishing colon cancer was 0.907. The sensitivity in the parallel mode was 87.6%, and the specificity in the serial mode was 98.2%. Compared with the low galectin-3 group, low AQP-1 group and low AQP-3 group, the survival time of patients in the high galectin-3 group (χ2 = 13.929, P < 0.001), high AQP-1 group (χ2 = 10.157, P = 0.001) and high AQP-3 group (χ2 = 4.364, P = 0.037) were significantly shortened. CONCLUSION: Galectin-3 combined with AQP-1 and AQP-3 had important value in the identification of young patients with colon cancer and was of great value in evaluating long-term prognosis.

Prognostic Value of Thyroid Hormone FT3 in General Patients Admitted to the Intensive Care Unit.

Low plasma triiodothyronine (T3) concentration indicates nonthyroidal illness syndrome (NTIS), which might be associated with a poor outcome in patients in the intensive care unit (ICU). This study evaluated the relationship between NTIS and prognostic indicators in patients admitted to the ICU and examined the fT3 cut-off points that could be associated with 28-day mortality. This prospective observational study included patients admitted to the ICU of The Third Hospital of Hebei Medical University from February to November 2018. The baseline variables and the occurrence of low free T3 (FT3) were collected. The patients were divided into the NTIS (FT3 < 3.28) and non-NTIS groups. Among 305 patients, 118 (38.7%) were in the NTIS group. FT3 (P < 0.001) and FT4 (P = 0.001) were lower, while the 28-day mortality rate (P < 0.001) and hospitalization expenses in ICU (P = 0.001) were higher in the NTIS group. The univariable analyses identified NTIS, FT3, free thyroxine/FT3, APACHEII, sequential organ failure score, duration of mechanical ventilation, creatinine, oxygenation index, white blood cells, albumin, age, and brain natriuretic peptide as being associated with 28-day mortality (all P < 0.05). The cut-off value of FT3 for 28-day mortality was 2.88 pmol/L. The 28-day mortality rate and hospitalization expenses in the ICU were higher in patients with NTIS. NTIS was independently associated with 28-day mortality.

Loss-of-function variants in FSIP1 identified by targeted sequencing are associated with one particular subtype of mucosal melanoma.

BACKGROUND: Mucosal melanoma is a tumor caused by the malignant transformation of pigment-producing cells and can arise from any mucosal tissue where melanocytes are present. Due to its rarity, the mucosal melanoma subtype is poorly described, and its genetic characteristics are infrequently studied. The discovery or confirmation of new mucosal melanoma susceptibility genes will provide important insights for the study of its pathogenesis. MATERIALS AND METHODS: We performed deep targeted sequencing of 100 previously reported melanoma-related genes in 39 mucosal melanoma samples and a gene-level loss-of-function (LOF) variant enrichment analysis for mucosal melanoma from different incidence sites. RESULTS: We detected 7,589 variants in these samples, and 484 were LOF variants (gain or loss of a stop codon, missense, and splice site). Four different gene-level enrichment analyses revealed that FSIP1 (fibrous sheath interacting protein 1) is a susceptibility gene for oral mucosal melanoma (OR = 0.33, PChi = 4.05 × 10-2, Pburden = 3.06 × 10-2, Pskat = 3.01 × 10-2, Pskato = 3.01 × 10-2), whereas the different methods did not detect a significant susceptibility gene for the other subtypes. CONCLUSIONS: In our study, a susceptibility gene for oral mucosal melanoma was confirmed in a Chinese Han population, and these findings contribute to a better genetic understanding of mucosal melanoma of different subtypes.
