ABSTRACT

【Objective】 To investigate the clinical characteristics and treatment strategy of giant multilocular prostatic cystadenoma(GMPC). 【Methods】 The clinical data of a GMPC patient treated in our hospital in July 2021 were retrospectively analyzed. The patient was 73 years old. The clinical manifestations were urgent urination and frequent urination. The prostate specific antigen (PSA) increased slightly. MRI showed giant cystic solid space occupying lesion of the prostate. Domestic and foreign cases of prostate cystadenoma from 2000 to 2021 were retrieved for literature review. 【Results】 Transabdominal laparoscopic radical prostatectomy was performed successfully. The postoperative pathological diagnosis was GMPC. Two weeks after operation, the urinary catheter was removed, and there was no discomfort such as urinary frequency or urinary incontinence. After follow-up for more than 8 months, there was no tumor recurrence or metastasis. 【Conclusion】 There are still some disputes about the oncological characteristics and diagnosis and treatment of GMPC, and there is a lack of long-term follow-up results. Laparoscopic prostatectomy is safe and feasible. Most patients have a good prognosis after surgical treatment. It is necessary to formulate an individualized standard treatment plan based on surgery combined with different patients’ conditions to actively improve the prognosis.

ABSTRACT

Aim To explore and verify the possible mechanism of Jiawei Duhuo Jisheng Mixture(JDJM)in the treatment on Knee Osteoarthritis(KOA)via using network pharmacology and animal experiment. Methods The ingredients of JDJM and relevant targets were collected from TCMSP and BATMAN-TCM database. The KOA-related targets were collected from GeneCard, OMIM and GEO databases. The common targets were acquired by intersecting ingredients-related and KOA-related targets, and then the Ingredient-Disease-Target Network and PPI network were constructed by Cytoscape 3.7.2 software and STRING platform. GO and KEGG enrichment analysis were performed based on Metascape database. Finally, the key targets and relevant mechanism were validated via animal experiment. Results In the network pharmacology study, 180 active ingredients related to treatment on KOA by JDJM were collected, and 152 common targets were confirmed. PPI network analysis showed that AKT1 might be the key targets of JDJM in the treatment on KOA. GO and KEGG enrichment analysis revealed that the key target mainly concentrated on inflammatory response and apoptosis. Animal experiment confirmed that JDJM could improve lesion in KOA rabbits, and suppress the expression levels of IL-1β, TNF-α, Caspase 3 and BAX in serum and articular fluid. AKT1 expression(including mRNA and protein)in articular cartilage was also down-regulated. Conclusions Based on the results of network pharmacology and animal experiment, JDJM may relieve KOA severity by anti-inflammatory and anti-apoptotic effects through a variety of molecular signaling pathways.

ABSTRACT

Objective: To explore carnosine dipeptidase 1 (CNDP1) potential value as a diagnostic and prognostic evaluator of hepatocellular carcinoma (HCC). Methods: A gene chip and GO analysis were used to screen the candidate marker molecule CNDP1 for HCC diagnosis. 125 cases of HCC cancer tissues, 85 cases of paracancerous tissues, 125 cases of liver cirrhosis tissues, 32 cases of relatively normal liver tissue at the extreme end of hepatic hemangioma, 66 cases from serum samples of HCC, and 82 cases of non-HCC were collected. Real-time fluorescent quantitative PCR, immunohistochemistry, western blot, and enzyme-linked immunosorbent assay were used to detect the differences in mRNA and protein expression levels of CNDP1 in HCC tissue and serum. Receiver operating characteristic (ROC) curves and Kaplan-Meier survival were used to analyze and evaluate the value of CNDP1 in the diagnosis and prognosis of HCC patients. Results: The expression level of CNDP1 was significantly reduced in HCC cancer tissues. The levels of CNDP1 were significantly lower in the cancer tissues and serum of HCC patients than those in liver cirrhosis patients and normal controls. ROC curve analysis showed that the area under the curve of serum CNDP1 in the diagnosis of HCC patients was 0.753 2 (95% CI 0.676-0.830 5), and the sensitivity and specificity were 78.79% and 62.5%, respectively. The combined detection of serum CNDP1 and serum alpha-fetoprotein (AFP) significantly improved the diagnostic accuracy (AUC = 0.820 6, 95% CI 0.753 5-0.887 8). The diagnostic sensitivity and specificity of serum CNDP1 for AFP-negative HCC patients were 73.68% and 68.75% (AUC = 0.793 1, 95% CI 0.708 8-0.877 4), respectively. In addition, the level of serum CNDP1 distinguished small liver cancer (tumor diameter < 3 cm) (AUC = 0.757 1, 95% CI 0.637 4-0.876 8). Kaplan-Meier survival analysis showed that CNDP1 was associated with a poor prognosis in HCC patients. Conclusion: CNDP1 may be a potential biomarker for the diagnostic and prognostic evaluation of HCC, and it has certain complementarity with serum AFP.

ABSTRACT

OBJECTIVE@#To investigate the regulatory effect of interferon-α (IFN-α) on the apoptosis and killing function of CD56dimCD57+ natural killer (NK) cells in systemic lupus erythematosus (SLE) patients, and to explore the specific mechanism.@*METHODS@#A total of sixty-four newly treated SLE patients and sixteen healthy controls (HC) enrolled in the Second Hospital of Dalian Medical University were selected as the research subjects. And the gene expression levels of molecules related to NK cell-killing function were detected by real-time quantitative polymerase chain reaction. CD56dimCD57+ NK cells were co-cultured with the K562 cells, and the apoptotic K562 cells were labeled with Annexin-Ⅴ and 7-amino-actinomycin D. Peripheral blood mononuclear cells were treated with 20, 40, and 80 μmol/L hydrogen peroxide (H2O2), and treated without H2O2 as control, the expression level of perforin (PRF) was detected by flow cytometry. The concentration of IFN-α in serum was determined by enzyme linked immunosorbent assay. The expression levels of IFN-α receptors (IFNAR) on the surface of CD56dimCD57+ NK cells were detected by flow cytometry, and were represented by mean fluorescence intensity (MFI). CD56dimCD57+ NK cells were treated with 1 000 U/mL IFN-α for 24, 48 and 72 h, and no IFN-α treatment was used as the control, the apoptosis and the expression levels of mitochondrial reactive oxygen species (mtROS) were measured by flow cytometry and represented by MFI.@*RESULTS@#Compared with HC(n=3), the expression levels of PRF1 gene in peripheral blood NK cells of the SLE patients (n=3) were decreased (1.24±0.41 vs. 0.57±0.12, P=0.05). Compared with HC(n=5), the ability of peripheral blood CD56dimCD57+ NK cells in the SLE patients (n=5) to kill K562 cells was significantly decreased (58.61%±10.60% vs. 36.74%±6.27%, P < 0.01). Compared with the control (n=5, 97.51%±1.67%), different concentrations of H2O2 treatment significantly down-regulated the PRF expression levels of CD56dimCD57+ NK cells in a dose-dependent manner, the 20 μmol/L H2O2 PRF was 83.23%±8.48% (n=5, P < 0.05), the 40 μmol/L H2O2 PRF was 79.53%±8.56% (n=5, P < 0.01), the 80 μmol/L H2O2 PRF was 76.67%±7.16% (n=5, P < 0.01). Compared to HC (n=16), the serum IFN-α levels were significantly increased in the SLE patients (n=45) with moderate to high systemic lupus erythematosus disease activity index (SLEDAI≥10) [(55.07±50.36) ng/L vs. (328.2±276.3) ng/L, P < 0.001]. Meanwhile, compared with HC (n=6), IFNAR1 expression in peripheral blood CD56dimCD57+ NK cells of the SLE patients (n=6) were increased (MFI: 292.7±91.9 vs. 483.2±160.3, P < 0.05), and compared with HC (n=6), IFNAR2 expression in peripheral blood CD56dimCD57+ NK cells of the SLE patients (n=7) were increased (MFI: 643.5±113.7 vs. 919.0±246.9, P < 0.05). Compared with control (n=6), the stimulation of IFN-α (n=6) significantly promoted the apoptosis of CD56dimCD57+ NK cells (20.48%±7.01% vs. 37.82%±5.84%, P < 0.05). In addition, compared with the control (n=4, MFI: 1 049±174.5), stimulation of CD56dimCD57+ NK cells with IFN-α at different times significantly promoted the production of mtROS in a time-dependent manner, 48 h MFI was 3 437±1 472 (n=4, P < 0.05), 72 h MFI was 6 495±1 089 (n=4, P < 0.000 1), but there was no significant difference at 24 h of stimulation.@*CONCLUSION@#High serum IFN-α level in SLE patients may induce apoptosis by promoting mtROS production and inhibit perforin expression, which can down-regulate CD56dimCD57+ NK killing function.

ABSTRACT

OBJECTIVE@#To investigate the imaging effect of a near-infrared fluorescent targeted probe ICG-NP41 on the neurovascular bundles (NVB) around the prostate in rats.@*METHODS@#A near-infrared fluorescent targeted probe ICG-NP41 was synthesized. An animal model for NVB imaging was established using Sprague-Dawley rats (250-400 g). Experiments were conducted using a custom-built near-infrared windowⅡ(NIR-Ⅱ) small animal in vivo imaging system, and images collected were processed using ImageJ and Origin. The fluorescence signal data were statistically analyzed using GraphPad Prism. The signal-to-background ratio (SBR) for NVB was quantitatively calculated to explore the effective dosage and imaging time points. Finally, paraffin pathology sections and HE staining were performed on the imaging structures.@*RESULTS@#Except for rats in the control group (n=2), right-sided NVB of the rats injected with ICG-NP41 (n=2 per group) were all observed in NIR-Ⅱ fluorescence mode 2 h and 4 h after administration. At 2 h and 4 h, average SBR of cavernous nerve in 2 mg/kg group in fluorescence mode was 1.651±0.142 and 1.619±0.110, respectively, both higher than that in white light mode (1.111±0.036), with no significant difference (P>0.05); average SBR of 4 mg/kg group in fluorescence mode were 1.168±0.066 and 1.219±0.118, respectively, both higher than that in white light mode (1.081±0.040), with no significant difference (P>0.05). At 2 h and 4 h, the average SBR of 2 mg/kg and 4 mg/kg groups in fluorescence mode were higher than that of the control group (SBR=1), the average SBR of the 2 mg/kg group was higher than that of the 4 mg/kg group, and all the above with no significant difference (P>0.05). The average diameter of the nerve measured by full width at half maxima method was about (178±15) μm. HE staining of paraffin sections showed the right major pelvic ganglion.@*CONCLUSION@#The near-infrared fluorescent targeted probe ICG-NP41 can be used for real-time imaging of the NVB around the prostate in rats, providing a potential feasible solution for localizing NVB in real time during nerve-sparing radical prostatectomy.

ABSTRACT

OBJECTIVE@#To investigate the treatment outcome of laparoscopic partial nephrectomy in the patients with renal tumors of moderate to high complexity (R.E.N.A.L. score 7-10).@*METHODS@#In the study, 186 patients with a renal score of 7-10 renal tumors who underwent laparoscopic partial nephrectomy in Peking University Third Hospital from February 2016 to April 2021 were selected. Laparoscopic partial nephrectomy was performed after examination. The patients were followed-up, and their postoperative hemoglobin, creatinine, complications, and length of hospital stay recorded. The data were represented by mean±standard deviation or median (range).@*RESULTS@#There were 128 males and 58 females in this group, aged (54.6±12.8) years, with body mass index of (25.4 ± 3.4) kg/m2; The tumors were located in 95 cases on the left and 91 cases on the right, with maximum diameter of (3.1±1.2) cm. The patient's preoperative hemoglobin was (142.9±15.8) g/L, and blood creatinine was 78 μmol/L (47-149 μmol/L). According to preoperative CT images, the R.E.N.A.L. score was 7 points for 43 cases, 8 points for 67 cases, 9 points for 53 cases, and 10 points for 23 cases. All the ope-rations were successfully completed, with 12 cases converted to open surgery. The operation time was 150 minutes (69-403 minutes), the warm ischemic time was 25 minutes (3-60 minutes), and the blood loss was 30 mL (5-1 500 mL). There were 9 cases of blood transfusions, with a transfusion volume of 800 mL (200-1 200 mL). Postoperative hemoglobin was (126.2±17.0) g/L. The preoperative crea-tinine was 78 μmol/L (47-149 μmol/L), the postoperative creatinine was 83.5 μmol/L (35-236 μmol/L), the hospital stay was 6 days (3-26 days), and surgical results achieved "the trifecta" in 87 cases (46.8%). In the study, 167 cases were followed up for 12 months (1-62 months), including 1 case with recurrence and metastasis, 4 cases with metastasis, and 2 cases with other tumors (1 case died).@*CONCLUSION@#Laparoscopic partial nephrectomy is safe and effective in the treatment of renal tumors with R.E.N.A.L. score of 7-10. Based on the complexity of the tumor, with the increase of difficulty, the warm ischemia time and operation time tend to increase gradually, while "the trifecta" rate gradually decreases. The complications of this operation are less, and the purpose of preserving renal function to the greatest extent is achieved.

ABSTRACT

OBJECTIVE@#To retrospectively analyze clinical data of patients under 40 years old who underwent surgical treatment for renal tumors with tumor thrombus from January 2016 to December 2022 at Peking University Third Hospital, and to evaluate the surgical effect and investigate the relationship between clinicopathological characteristics and prognosis.@*METHODS@#The clinical data of 17 young patients with renal tumor thrombus were retrospectively analyzed, and the clinicopathological features and prognosis were summarized. The patients were grouped according to the presence or absence of symptoms, 2017 American Joint Committee on Cancer (AJCC) clinical stage, and postoperative combined adjuvant therapy. Kaplan-Meier method was used to plot the survival curve, and Log-rank test was used to compare the differences in postoperative survival time and progression-free survival time between the different groups. The relationship between clinicopathological features and prognosis was analyzed.@*RESULTS@#All the 17 patients received venous tumor thrombectomy, including 16 patients (94.1%) who underwent radical nephrectomy and 1 patient (5.9%) who underwent partial nephrectomy. Twelve patients (70.6%) had symptoms and 5 (29.4%) had no symptoms before operation. A total of 17 renal tumors were observed, with 2 patients (11.8%) identified as benign and 15 patients (88.2%) classified as malignant. Among the malignant tumors, 1 patient (6.7%) was diagnosed as clear cell carcinoma, while the remaining 14 patients (93.3%) were categorized as non-clear cell carcinoma. In terms of tumor stage, 8 patients (53.3%) were classified as stage Ⅲ according to the AJCC classification, while 7 patients (46.7%) were categorized as stage Ⅳ. Additionally, 6 patients (40%) received multiple adjuvant therapy, while 9 patients (60%) did not undergo such treatment. The follow-up period ranged from 2 to 78 months, with a median follow-up of 41 months. During this time, 3 patients (20%) died. The median survival time after surgery was 39.0 (2.3, 77.8) months, and the progression-free survival time was 16.4 (2.3, 77.8) months. There was no significant difference in postoperative survival time and progression-free survival time among young patients with renal tumor with tumor thrombus, based on the presence of symptoms before surgery (P=0.307, P=0.302), clinical stage of AJCC (P=0.340, P=0.492), and postoperative adjuvant therapy (P=0.459, P=0.253) group.@*CONCLUSION@#The pathological types of young patients with renal tumor with tumor thrombus are more complex and varied due to symptoms, and the proportion of non-clear cell carcinoma in malignant tumor with tumor thrombus is higher. Symptomatic and non-clear cell carcinoma may be potentially associated with poor prognosis. Surgical operation combined with adjuvant therapy is a relatively safe and effective treatment for young patients with renal tumor and tumor thrombus.

ABSTRACT

@#Objective    To explore the effect of continuous nursing on lung transplant patients at home based on humanistic care. Methods    According to hospitalization order, patients who received lung transplantation in our hospital from January 2016 to October 2020 were divided into a control group and a nursing group. The control group was treated with routine lung transplantation education and regular follow-up after discharge, and the nursing group received humanistic care during follow-up, health education at discharge, cultural exchange activities, and home care plans. After discharge, the self-management ability at home, medication adherence and satisfaction of home care between the two groups were campared. Results    A total of 60 patients were included in the study. There were 23 patients in the control group, including 16 males and 7 females, with an average age of 58.70±11.00 years. There were 37 pateints in the nursing group, including 25 males and 12 females, with an average age of 57.90±13.20 years. The scores of self-management ability at home of the nursing group (self-concept 27.41±2.37 points vs. 21.78±3.54 points; self-care responsibility 20.73±1.63 points vs. 16.83±2.79 points; self-care skills 41.46±3.77 points vs. 28.26±4.11 points; health knowledge level 57.95±4.10 points vs. 44.87±5.79 points) were higher than those in the control group (all P<0.05). The medication adherence (7.47±0.46 points vs. 6.87±0.28 points) and satisfaction of home care (23.80±1.20 points vs. 20.50±1.90 points) in the nursing group were higher than those in the control group (both P<0.05). Conclusion    Continuous nursing based on humanistic care for lung transplant patients can effectively improve the self-management ability, medication adherence and nursing satisfaction of patients after discharge.

The recommended doses for sunitinib, axitinib, and pazopanib are 50mg qd, 5mg q12h, and 800mg qd, respectively. The primary endpoint of this study was disease-free survival (DFS), and the secondary endpoint was overall survival (OS). Statistical analyses were performed using R v4.2.2. Confounding factors were adjusted using propensity score weighting. Results:The median follow-up time for DFS was 29 months in the adjuvant therapy group and not reached in the control group, while median follow-up time for OS was 28 and 26 months, respectively. In the univariate Cox regression analysis, there were no statistically significant difference in the impact of all baseline characteristics and exposure factors on DFS and OS between the two groups. In survival analysis, there were no significant difference between DFS and OS curves of patients in the adjuvant therapy group and the control group (DFS, P=0.62; OS, P=0.74). The median DFS of patients in the adjuvant therapy group and the control group were 17 and 19 months, respectively, while the median OS was 43 and 27 months. After adjusting for confounding factors, the median DFS of patients in the adjuvant therapy group and the control group were 26 and 12 months, respectively, and the median OS remained 43 and 27 months, with no significant difference (DFS, P=0.81; OS, P=0.40). Conclusion:There is currently a lack of definitive evidence for survival benefit from adjuvant anti-VEGF/VEGFR targeted therapy in patients with cM0 nccRCC-VTT after surgery.

Objective:To investigate the effect of different imaging classifications of prostate cancer seminal vesicle invasion on positive surgical margins (PSM) after laparoscopic radical prostatectomy(LRP).Methods:114 patients with pT 3b stage prostate cancer admitted to Peking University Third Hospital from August 2009 to December 2020 were retrospectively analyzed. The age of the patients was (68.2±7.7) years old, the median pre-biopsy PSA was 20.20 (3.45-186.30) ng/ml, and the patients with biopsy Gleason score of ≤7, and ≥8 was 33 and 81 cases, respectively. The median prostate volume was 33.2 (12.1-155.4) ml. According to the imaging of the seminal vesicle invasion of prostate cancer, the patients were divided into the following types: type Ⅰ, the tumor directly invades the seminal vesicle along the vas deferens; type Ⅱa, the tumor invades the basal capsule of the prostate and invades the seminal vesicle; type Ⅱb, the tumor invades the periprostatic fat and retrogradely invades the seminal vesicles; type Ⅲ, solitary lesions in the seminal vesicles that do not continue with the prostate cancer. All patients underwent LRP, and the PSM were recorded as the base, bilateral, posterior, anterior and apical parts of the prostate. The differences in clinicopathological data of patients with different seminal vesicle invasion imaging types were compared, and the independent risk factors of PSM in pT 3b prostate cancer were evaluated by multivariate analysis. Results:The operative time of 114 cases in this group was (229.4±62.2) min, and the blood loss was 100(20-1 800)ml. The postoperative gross pathological Gleason score was ≤7 in 17 cases and ≥8 in 97 cases. In the imaging classification of prostate cancer with seminal vesicle invasion, there were 28 cases (24.6%) of type Ⅰ, 39 cases (34.2%) of type Ⅱa, 47 cases (41.2%) of type Ⅱb, and no type Ⅲ patients. There was no significant difference in age, body mass index, pre-biopsy PSA, prostate volume, and operation time among patients with type Ⅰ, Ⅱa, and Ⅱb seminal vesicle invasion ( P>0.05). There was a statistically significant difference in blood loss among the three types ( P = 0.001), and the difference in the proportion of lymph node metastasis was statistically significant ( P = 0.013). In the classification of prostate cancer seminal vesicle invasion, the PSM rates of type Ⅰ, Ⅱa and Ⅱb were 28.6% (8/28), 38.5% (15/39) and 70.2% (33/39), and the difference was statistically significant ( P=0.001). The PSM rates of type Ⅰ, Ⅱa, and Ⅱb were 21.4% (6/28), 23.1% (9/39), and 34.0% (16/47), respectively. The results of univariate analysis showed that the biopsy Gleason score ( P = 0.063) and the type of seminal vesicle invasion ( P<0.001) entered into multivariate analysis, and the results of multivariate logistic regression analysis showed that the type of seminal vesicle invasion ( P=0.001) was independent risk factor for PSM after LRP. Conclusions:The PSM rate in patients with type Ⅱb seminal vesicle invasion is significantly higher. The higher imaging type of seminal vesicle invasion is the independent risk factor of PSM after LRP.

ABSTRACT

Objective:By analyzing factors associated with lower urinary tract symptoms in middle-aged and elderly women aged 55-65 years old, a nomogram model for lower urinary tract symptoms was constructed to assist the clinical development of targeted interventions to reduce the incidence of lower urinary tract symptoms in this population.Methods:In the cross-sectional study, 798 middle-aged and elderly women aged 55-65 years receiving physical examination in the Health Management Center of Third Xiangya Hospital from November 2013 to December 2020 were selected as research participants.Univariate regression analysis was used to compare differences in the basic data related to lower urinary tract symptoms in the population.Multivariate Logistic regression analysis was used to identify related influencing factors, and a nomogram model for lower urinary tract symptoms in the population was established.Results:Among 798 middle-aged and elderly women surveyed, the prevalence of lower urinary tract symptoms was 81.08 %(647 cases), and the rate of urinary tract infections was 21.48 %(139 cases). Variables with statistical significance in univariate regression analysis were included in multivariate Logistic regression analysis.The results showed that body mass index, vaginal delivery, strength of pelvic floor type Ⅱ fiber muscle, pelvic and abdominal coordination and mental health were independent influencing factors for lower urinary tract symptoms in middle-aged and elderly women aged 55-65 years( OR=1.099, 2.681, 0.895, 0.658, 1.057, P=0.010, 0.030, 0.040, 0.010, 0.038). The monogram model based on the five risk prediction indexes produced a consistency index(C-index)of 0.651 and a diagnostic sensitivity and specificity of 66.9% and 58.9%, respectively.The correction curve showed that the predicted results of the model were essentially the same as the actual probability of condition. Conclusions:In this study, the independent influencing factors for lower urinary tract symptoms in middle-aged and elderly women aged 55-65 years were screened by univariate regression and multivariate Logistic regression analysis and a nomogram model for risk prediction of the population was constructed, was proved to have a good ability for accurately and effectively predicting the risk of lower urinary tract symptoms in middle-aged and elderly women aged 55-65 years, and will assist clinicians to screen for high-risk patients, formulate targeted interventions, and reduce the incidence of lower urinary tract symptoms in middle-aged and elderly women aged 55-65 years.

ABSTRACT

Objective:To evaluate the effect of high-flow nasal cannula (HFNC) therapy on patients with moderate acute respiratory failure.Methods:This was a randomized controlled trial. The patients with moderate acute respiratory failure in the Intensive Care Unit (ICU) of Changshu Hospital Affiliated to Soochow University from March 2019 to September 2020 were included. Patients with severe asthma or acute exacerbation of chronic respiratory failure, hemodynamic instability, disturbance of consciousness, non-invasive ventilation (NIV) contraindication, urgent need for endotracheal intubation, refusal of intubation, age <18 years and pregnancy were excluded. The patients were randomized to HFNC or NIV. Treatment failure was defined as the need for intubation and invasive ventilation. The vital signs, ROX index, blood gas analysis index, ultrasound parameters and endotracheal intubation rate were recorded at 1, 6, 12, 24 and 48 h after treatment. Kaplan-Meier method was used to draw the survival curve, and multivariate logistic regression was used to analyze the risk factors of treatment failure.Results:A total of 91 patients were included in the study, including 46 patients in the HFNC group and 45 patients in the NIV group. PaO 2/FiO 2 of the two groups were significantly increased after treatment compared with baseline ( P<0.05). The respiratory rate was lower in the NIV group than in the HFNC group at 1 and 24 h ( P<0.05). There were no significant differences in other vital signs, arterial blood gas and ultrasound parameters between the two groups (all P>0.05). The intubation rate was 52.2% in the HFNC group and 48.9% in the NIV group. Kaplan-Meier survival analysis showed that there was no significant difference in intubation rate and mortality between the two groups ( P>0.05). Multivariate logistic regression analysis showed that increased end-diastolic right ventricle/left ventricle ratio ( OR=1.044, 95% CI: 1.012~1.077) and high acute physiology and chronic health evaluationⅡ score ( OR=1.082, 95% CI: 1.006~1.163) at 0 h, lung ultrasound score ( OR=1.353, 95% CI: 1.034~1.772) and end-diastolic RV/LV ratio ( OR=1.097, 95% CI: 1.038~1.159) at 1 h were independent risk factors for non-invasive respiratory strategies failure. Increased diaphragm excursion ( OR=0.341, 95% CI: 0.165~0.704) at 0 h, high PaO 2/FiO 2 ( OR=0.929, 95% CI: 0.884~0.977), increased ROX index ( OR=0.524, 95% CI: 0.332~0.826), and increased diaphragm mobility ( OR=0.119, 95% CI: 0.030~0.476) at 1 h were independent protective factor for successful treatment. Conclusions:HFNC and NIV can improve oxygenation in patients with acute hypoxemic respiratory failure. There is no significant difference in intubation rate and mortality between HFNC and NIV. Ultrasound parameters may be helpful for predicting treatment failure.

ABSTRACT

Aim To investigate the potential mechanism of Jiawei Duhuo Jisheng Mixture regulating intestinal flora in the treatment of knee osteoarthritis(KOA)by 16S rRNA sequencing.Methods Eight-week-old male C57 mice were randomly divided into three groups:sham group,DMM group,and model+Jiawei Duhuo Jisheng Mixture group(Mixture group),6 mice per group.KOA model was induced by destabilization of medial meniscus surgery.16.25 mL·kg-1 dose mixture was given daily to the mixture group,and normal saline was given to the sham and DMM group.After eight weeks,the knee joints and colons of mice were collected,and the knee joints were prepared into paraffin sections,and the cartilage changes were observed with Safranin O-Fast Green and immunohistochemistry staining.16S rRNA sequencing of intestinal contents was performed to observe the changes of intestinal flora.Results Compared with model group,Jiawei Duhuo Jisheng Mixture could significantly reduce cartilage wear and OARSI score(P=0.033 5,P=0.029 5).16S rRNA sequencing showed that Jiawei Duhuo Jisheng Mixtrue could change the intestinal flora richness of KOA model mice,and improve the Alpha diversity(Chao1,Simpson)and Beta diversity(PCoA,NMDS).LefSe analysis showed that there were species with significant difference in abundance among the three groups(P=0.001),mainly including Lactobacillus,Firmicutes,Proteobacteria and other species.MetaCyc analysis indicated that Jiawei Duhuo Jisheng Mixture had effects on various metabolic pathways such as fatty acid,sugar and amino acid of intestinal flora(P<0.05).Conclusions Jiawei Duhuo Jisheng Mixtrue can effectively protect the articular cartilage and delay the progression of KOA.The mechanism may be through regulating the intestinal flora structure,protecting the intestinal barrier and reducing the inflammatory response.

ABSTRACT

Covalently closed circular DNA (cccDNA) of hepatitis B virus (HBV) is the template for HBV replication. Currently, there is a lack of therapeutic drugs that directly target cccDNA. Therefore, blocking cccDNA supplements as fast as possible and reducing the existing cccDNA is the key to achieving a complete cure of chronic hepatitis B. Previous studies have suggested that cccDNA had a long half-life, but a recent study showed that it only took a few months to update cycle of cccDNA pool, and its number was much less than previously predicted. In the future, with the advent of new antiviral drugs that can completely inhibit HBV replication, it is expected that the cccDNA pool will be completely cleared due to its supplement complete blockade, so as to achieve virological cure of chronic hepatitis B.
