A network pharmacology-based approach to explore mechanism of kaempferol-7 -O -neohesperidoside against prostate cancer / 中国药理学通报

Aim To explore the effect of kaempferol-7- 0-neohesperidoside (K70N) against prostate cancer (PCa) and the underlying mechanism. Methods The effect of K70N on the proliferation of PCa cell lines PC3, DU145, C4-2 and LNCaP was detected using CCK8 assay. The effect of K70N on migration ability of DU145 cells was determined by wound healing assay. The targets of K70N and PCa were screened from SuperPred and other databases. The common targets both related to K70N and PCa were obtained from the Venny online platform, a protein-protein interaction network (PPI) was constructed by the String and Cyto- scape. Meanwhile, the GO and KEGG functional enrichment were analyzed by David database. Then, a "drug-target-disease-pathway" network model was constructed. Cell cycle of PCa cells treated with K70N was analyzed by flow cytometry. The expressions of cycle-associated proteins including Skp2, p27 and p21 protein were detected by Western blot. Molecular docking between Skp2 and K70N was conducted by Sybyl X2. 0. Results K70N significantly inhibited the proliferation and migration of PCa cells. A total number of 34 drug-disease intersection targets were screened. The String results showed that Skp2 and p27, among the common targets, were the key targets of K70N for PCa treatment. Furthermore, GO and KEGG functional en-richment indicated that the mechanism was mainly related to the cell cycle. Flow cytometry showed that K70N treatment induced cell cycle arrest at the S phase. Compared with the control group, the protein expression level of Skp2 was significantly down-regulated, while the protein expression levels of p27 and p21 were up-regulated. The network molecular docking indicated that the ligand K70N had a good binding ability with the receptor Skp2. Conclusions K70N could inhibit the proliferation and migration of PCa cells, block the cell cycle in the S phase, which may be related to the regulation of cell cycle through the Skp2- p27/p21 signaling pathway.

Early Plasma Circulating Tumor DNA as a Potential Biomarker of Disease Recurrence in Non-metastatic Prostate Cancer / Journal of the Korean Cancer Association, 대한암학회지

Purpose@#In non-metastatic prostate cancer (nmPCa) setting, it is important to early identify the patients at risk of biochemical recurrence (BCR) for immediate postoperative intervention. Our study aimed to evaluate the potential clinical utility of circulating tumor DNA (ctDNA) for predicting disease recurrence. @*Materials and Methods@#This real-world observational study evaluated 161 cases of nmPCa undergoing next-generation sequencing at our institution. A total of 139 ctDNA samples and 31 biopsied tumor tissue underwent genomic profiling. The study endpoint was BCR after radical prostatectomy. Relationships between the ctDNA status and the biochemical progression-free survival (bPFS) were analyzed by log-rank test and multivariate Cox regression. @*Results@#Of 161 enrolled patients, 19 (11.8%) harbored deleterious alterations in NCOR2, followed by BRCA2 (3.7%), ATR (2.5%), and CDK12 (2.5%). Of available pre-operative blood samples (n=139), ctDNA was detectable in 91 (65.5%). Until last follow-up, 56 of 68 patients (85.3%) with detectable ctDNA had achieved BCR, whereas only eight of 39 patients (20.5%) with undetectable ctDNA had achieved BCR. Patients who had undetectable ctDNA experienced significantly longer bPFS compared with those who had detectable ctDNA (not available vs. 8.2 months; hazard ratio, 0.14; p < 0.01). Pre-operative ctDNA status was a significant prognostic factor of disease recurrence. @*Conclusion@#Pre-operative ctDNA detection could identify patients at high risk of recurrence and has the potential to inform immediate postoperative interventions, but these approaches remain to be validated in prospective studies. ctDNA studies can provide insights into accurate monitoring and precise treatment rather than simply following routine clinical care.

In recent years, the incidence of DOR has been increasing and the ages of patients are younger. The search for an effective DOR treatment has emerged as one of the preeminent research topics in reproductive health. An effective DOR therapy would improve ovarian function, fertility, and quality of life in patients. In this review we evaluated DOR treatment progress both in Western medicine and Chinese medicine, and elucidated the characteristics of each treatment.

Effect analysis of combined immunological blockade mother-to-child transmission of hepatitis B virus in Hainan Province from 2015 to 2020 / 中国热带医学

@#Abstract: Objective　To analyze the influencing factors of mother-to-child transmission of hepatitis B virus after combined immunological blockade, and to evaluate the effect of mother-to-child blockade, and to provide a basis for health policies and health interventions for preventing mother-to-child blockade of hepatitis B virus. Methods A total of 11 363 pairs of HBsAg positive pregnant women and their infants aged 7-12 months in Hainan Province from 2015 to 2020 were included in the study. The general situation, the situation of health care and delivery in this pregnancy and perinatal period, the detection of hepatitis B markers, the situation of antiviral therapy, the general situation of mother and infant during delivery and the implementation of blockade measures for mother-to-child transmission of hepatitis B were collected and analyzed. Results Among the 11 363 pairs of HBsAg positive pregnant women and their infants delivered in hospitals in Hainan province from 2015 to 2020, the positive rate of HBsAg in children at 7-12 months after birth was 1.47 %, and the difference in HBsAg positive rate of infants born in different years was not statistically significant (P>0.05). There were no significant differences in the positive rate of HBsAg among children born to pregnant women with different nationalities, educational levels, occupations, delivery modes, delivery places, obstetric operations and perineal laceration, abnormal perinatal period, children with different genders and premature delivery and perinatal (all P<0.05). There was significant difference in HBsAg positive rate among infants born to pregnant women of different ages, the positive rate of HBsAg of infants born to young pregnant women was higher than that of older pregnant women (P<0.05). The rate of antiviral therapy was low in HBeAg positive pregnant women, and the positive rate of HBsAg in their infants was 2.54%, which was higher than 0.83% in HBeAg negative pregnant women (P<0.05). Conclusions Combined immunological blockade with hepatitis B vaccine and hepatitis B immunoglobulin can effectively prevent the mother-to-child transmission of HBV. HBsAg-positive women can give birth at the right age, and HBeAg-positive pregnant women can be treated with antiviral therapy to block mother-to-child transmission, providing the important basis for the formulation of hepatitis B prevention and control strategies and measures.

PD-1 inhibitor plus anlotinib for metastatic castration-resistant prostate cancer: a real-world study / 亚洲男科学杂志(英文版)

Management and treatment of terminal metastatic castration-resistant prostate cancer (mCRPC) remains heavily debated. We sought to investigate the efficacy of programmed cell death 1 (PD-1) inhibitor plus anlotinib as a potential solution for terminal mCRPC and further evaluate the association of genomic characteristics with efficacy outcomes. We conducted a retrospective real-world study of 25 mCRPC patients who received PD-1 inhibitor plus anlotinib after the progression to standard treatments. The clinical information was extracted from the electronic medical records and 22 patients had targeted circulating tumor DNA (ctDNA) next-generation sequencing. Statistical analysis showed that 6 (24.0%) patients experienced prostate-specific antigen (PSA) response and 11 (44.0%) patients experienced PSA reduction. The relationship between ctDNA findings and outcomes was also analyzed. DNA-damage repair (DDR) pathways and homologous recombination repair (HRR) pathway defects indicated a comparatively longer PSA-progression-free survival (PSA-PFS; 2.5 months vs 1.2 months, P = 0.027; 3.3 months vs 1.2 months, P = 0.017; respectively). This study introduces the PD-1 inhibitor plus anlotinib as a late-line therapeutic strategy for terminal mCRPC. PD-1 inhibitor plus anlotinib may be a new treatment choice for terminal mCRPC patients with DDR or HRR pathway defects and requires further investigation.

Objective:To compare the efficacy and safety of radium-223 in the treatment of metastatic castration-resistant prostate cancer (mCRPC) patients with and without homologous recombination repair (HRR) gene mutation.Methods:The clinical data of 27 patients with mCRPC bone metastases who received radium-223 therapy from April 2021 to November 2022 in Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine were retrospectively analyzed. Among the 27 mCRPC patients, 18 patients carrying HRR gene mutations belonged to the HRD(+ ) group, and 9 patients without HRR gene mutation belonged to the HRD(-) group. The age of patients in HRD(+ ) group was 69.5 (63.8, 77.0) years old, alkaline phosphatase (ALP) was 243.0 (82.8, 301.3) U/L, prostate specific antigen (PSA) was 71.6 (7.3, 329.8) ng/ml, pain score was 3.0 (1.0, 5.0) points. Eastern Cooperative Oncology Group (ECOG) score ranged from 0 to 1 points in 7 cases, and 2 points in 11 cases. In the HRD(-) group, the median age was 72.0 (64.5, 76.5) years old, ALP was 88.0 (67.5, 260.6) U/L, PSA was 19.1 (1.1, 117.8) ng/ml, and pain score was 2.0 (0, 4.5) points. The ECOG score ranged from 0 to 1 in 4 cases, and 2 in 5 cases in the HRD(-) group. There was no significant difference in the above general data between the two groups ( P>0.05). All patients received radium-223 treatment every 4 weeks, no more than 6 times. The changes of ALP, PSA, pain score and hematological adverse reactions were compared between the two groups. Results:In the HRD(+ ) group, the median number of radium-223 treatment was 4.5 (3.0, 5.3) couses, 4 patients (22.2%) completed 6 courses, and 6 patients died of prostate cancer during follow-up. In the HRD(-) group, the median number of radium treatment was 4.0 (2.5, 6.0) couses, 3 patients (33.3%) completed 6 courses, and 1 patient died of prostate cancer during follow-up. There was no significant difference in the number of radium treatment courses between the two groups ( P=0.320). ALP in HRD(+ ) group was 101.8 (61.3, 147.0) U/L after radium-223 treatment, which was significantly lower than that before treatment ( P=0.002). ALP in HRD(-) group was 73.0 (64.0, 113.5) U/L after radium-223 treatment, and it was not significantly different from that before treatment ( P=0.327). The rate of ALP response (ALP decrease >10%) in HRD(+ ) group was significantly higher than that in HRD(-) group [83.3% (15/18) vs. 44.4% (4/9), P=0.037]. PSA was 105.9(5.2, 798.4) ng/ml in HRD (+ ) group after radium-223 treatment, and was 25.6(0.8, 1 031.0) ng/ml in HRD(-) group, and they were not significantly different from that before treatment ( P=0.145, P=0.386). There were no significant differences in the rate of PSA response (PSA decrease>10%) between HRD(+ ) group and HRD(-) group [38.9% (7/18) vs. 22.2% (2/9), P=0.386]. The median pain score of HRD(+ ) group was 3.0 (0, 4.0) points after treatment, which was significantly lower than that before treatment ( P=0.028). The pain score of HRD(-) group was 1.0(0, 3.0) points after treatment, and it was not significantly different from that before treatment ( P=0.129). There was no significant difference in pain relief rate between HRD(+ ) group and HRD(-) group [66.7% (12/18) vs. 44.4% (4/9), P=0.411]. The incidence of at least one hematological adverse event during radium-223 treatment in the HRD(+ ) group was higher than that in the HRD(-) group [77.8% (14/18) vs. 33.3% (3/9), P=0.039]. There was no significant difference in the incidence of grade 1-2 hematological adverse events between the two groups [72.2%(13/18) vs. 33.3%(3/9), P=0.097]. Only 1 patient in the HRD(+ ) group experienced grade 3 anemia during treatment which was recovered after blood transfusion. Conclusions:Compared to mCRPC patients without HRR gene mutation, patients with HRR gene mutations had better ALP response and bone pain relief after radium-223 treatment. The overall incidence of adverse events in the HRD(+ ) group is higher than that in HRD(-) group, and there was no significant difference in grade 1-2 hematological adverse events between the two goups. It is necessary to expand the sample size to further verify the conclusion.

Efficacy of first-line tyrosine kinase inhibitors plus immune checkpoint inhibitors in metastatic fumarate hydratase-deficient renal cell carcinoma / 中华泌尿外科杂志

Objective:To evaluate the efficacy of first-line tyrosine kinase inhibitors (TKI) plus immune checkpoint inhibitors (ICI) in metastatic fumarate hydratase-deficient renal cell carcinoma (FH-deficient RCC).Methods:The data of 87 metastatic FH-deficient RCC patients from West China Hospital ( n=44), Renji Hospital ( n=27) and Sun Yat-sen University Cancer Center (n=16) from Mar 2019 to Aug 2022 were retrospectively analyzed. The median age was 37(30, 47) years, the male to female ratio was 1.9∶1. The median size of tumor was 7.5(5.0, 10.0) cm. Sixty-one patients (70.1%) had germline FH mutations, and 26 patients (29.9%) had somatic FH mutations. Forty-nine patients (56.3%) metastasis disease at initial diagnosis, and 38 patients (43.7%) had metachronous metastasis. The most common site of metastasis was lymph node (41/87, 47.1%), followed by bone (33/87, 37.9%), liver (22/87, 25.3%), and lung (14/87, 16.1%). Fifteen patients (17.2%) had weak expression of FH protein and 59 patients (67.8%) had positive PD-L1 expression. The most common treatments were sintilimab plus axitinib (52/87, 59.8%), followed by pembrolizumab plus cabozantinib (7/87, 8.0%), tirelizumab plus axitinib (6/87, 6.9%), pembrolizumab plus axitinib (5/87, 5.7%), and toripalimab plus axitinib (4/87, 4.6%). Thirteen patients (13/87, 14.9%) received other ICI plus TKI combination treatments. Statistical analysis was conducted using R 4.2.3 software. Kaplan Meier survival curve was used to evaluate survival data, and log-rank test was used to compare differences between treatment groups. Results:The overall objective response rate (ORR) and disease control rate (DCR) of first-line TKI + ICI were 39.1% and 89.7%, respectively. The median progression-free survival (PFS) and overall survival (OS) were 16.5 months and 71.0 months, respectively. For first-line sintilimab plus axitinib, the ORR and DCR were 44.2% and 92.3%, respectively. The median PFS was 17.3 months and the median OS was not reached for this combination treatment. The efficacy of first-line tirelizumab plus axitinib was inferior to other treatment strategies (median PFS: 4.0 vs. 16.6 months, P<0.001; median OS: 22.0 vs. 71.0 months, P=0.043). Subgroup analyses further showed that the efficacy of ICI+ TKI combination therapy was consistent in patients with different clinicopathologic and genomic features. However, patients with liver metastasis had shorter OS than those without liver metastasis (median OS: 26.3 vs. 71.0 months, P=0.021). Conclusion:First-line TKI + ICI is effective for metastatic FH-deficient RCC and can significantly prolong the survival of the patients.

Effect of different doses of compound sodium chloride injection combined with norepinephrine on prevention of hypotension after lumbar anesthesia in patients undergoing caesarean section / 中华麻醉学杂志

Objective:To evaluate the effect of different doses of compound sodium chloride injection combined with norepinephrine on prevention of hypotension after lumbar anesthesia in the patients undergoing caesarean section.Methods:A total of 150 patients with a singleton fetus, aged 18-45 yr, at ≥37 weeks of gestation, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, with height ≥150 cm, weighing ≤100 kg, with body mass index < 40 kg/m 2, scheduled for elective caesarean section under lumbar anesthesia, were divided into 3 groups ( n=50 each) by the random number table method: compound sodium chloride injection 4, 8 and 12 ml·kg -1·h -1 groups (group A, group B, group C). Compound sodium chloride injection 4 ml/kg was intravenously injected for liquid preload before lumbar anesthesia, and 0.5% hyperbaric bupivacaine 12.5 mg was injected to the subarachnoid space for lumbar anesthesia. Norepinephrine was intravenously injected at a dose of 6 μg immediately after intrathecal injection, followed by an infusion of 0.05 μg·kg -1·min -1, and infusion was stopped at 5 min after delivery. Compound sodium chloride injection was intravenously infused simultaneously at a rate of 4, 8 and 12 ml·kg -1·h -1 in A, B and C groups, respectively. The maximum diameter of inferior vena cava (IVCmax) and the minimum diameter of inferior vena cava (IVCmin) were measured by ultrasound, and inferior vena cava collapse index (IVC-CI) was calculated at 1 min before fluid preload (T 1), immediately after fluid preload (T 2), at 5 min after anesthesia (T 3), at 5 min after fetal delivery (T 4) and immediately before leaving the operating room (T 5). The incidence of intraoperative adverse events (hypotension, severe hypotension, bradycardia, hypertension, nausea, and vomiting) and neonatal outcomes (umbilical artery blood gas index and Apgar score at 1 and 5 min after birth) were recorded. Results:Compared with group A, IVCmin was significantly increased and IVC-CI was decreased at T 5 in group B, and IVCmin and IVCmax were significantly increased and IVC-CI was decreased at T 5 in group C ( P<0.05). There was no significant difference in IVCmax, IVCmin and IVC-CI at each time point between group B and group C ( P>0.05). There was no significant difference in the incidence of hypotension, severe hypotension, bradycardia, hypertension, nausea and vomiting among the three groups ( P>0.05). There was no significant difference in the results of blood gas analysis of the umbilical artery and Apgar score at each time point after birth among the three groups ( P>0.05). Conclusions:Compound sodium chloride injection 4, 8 and 12 ml·kg -1·h -1 combined with norepinephrine can effectively prevent the occurrence of hypotension after lumbar anesthesia in the patients undergoing caesarean section without increasing maternal and infant adverse events, and the effect of 8 and 12 ml·kg -1·h -1 for volume supplementation is better than that of 4 ml·kg -1·h -1.

Effect and influencing factors of prosthesis placement angle on hip replacement for bone fusion of hip joint / 局解手术学杂志

Objective To explore the effect and influencing factors of prosthesis placement angle on hip replacement for bone fusion of hip joint.Methods A total of 100 patients with bone fusion of hip joint who were admitted to our hospital from May 2019 to January 2022 were selected as the research objects and randomly divided into the observation group(n=50)and the control group(n=50).The prosthesis placement angle was 30° to 40° in the observation group and 41° to 50° in the control group.The clinical data,VAS score and Harris score before and after operation,and postoperative complications of the two groups were compared.The improvement of hip joint function of the two groups was compared by random walking model.According to the prognosis of patients,patients were divided into the poor prognosis group(n=32)and the good prognosis group(n=68).Univariate and multivariate Logistic regression analysis were used to analyze the independent influencing factors of the prognosis of hip replacement for bone fusion of hip joint,and a prediction model was constructed and verified.Results The Harris score 6 months after operation in the observation group was significantly higher than that in the control group(P<0.05),and there was no significant difference in VAS score before and after operation and incidence of complications after operation between the two groups(P>0.05).The results of random walking model showed that the improvement of hip joint function in the observation group was better than that in the control group.There were significant differences in age,hyperlipidemia,osteoporosis,prosthesis placement angle,intraoperative blood loss,emotional disorder,postoperative complications,rehabilitation training and postoperative outdoor activity time of patients between the good prognosis group and the poor prognosis group(P<0.05).Multivariate Logistic regression analysis showed that osteoporosis and prosthesis placement angle of 41° to 50° were the independent risk factors of the prognosis of hip replacement for bone fusion of hip joint(P<0.05),and rehabilitation training was the protective factor(P<0.05).A prediction model of the prognosis of hip replacement for bone fusion of hip joint was constructed.The calibration curve of the model fit well with the ideal curve,and the area under the receiver operating characteristic curve(AUC)was 0.854(95%CI:0.830 to 0.871),which indicates that the prediction model had good accuracy.The concordance index(C-index)of the model was 0.849(95%CI:0.817 to 0.868),which indicates that the model had high discrimination.Conclusion The prosthesis placement angle of 30° to 40° can significantly improve the postoperative hip joint function of patients,and the therapeutic effect is significant.Osteoporosis,prosthesis placement angle,and rehabilitation training are the independent influencing factors of the prognosis of hip replacement for bone fusion of hip joint.

Escore Albumina-Bilirrubina para Predizer Desfechos em Pacientes com Cardiomiopatia Dilatada Idiopática / Albumin-Bilirubin Score to Predict Outcomes in Patients with Idiopathic Dilated Cardiomyopathy

Resumo Fundamento: A disfunção hepática é uma variável postulada de prognóstico desfavorável na cardiomiopatia dilatada (CMD). Objetivo: Este estudo teve como objetivo investigar o valor prognóstico do escore albumina-bilirrubina (ALBI), um modelo relativamente novo para a avaliação da função hepática, em pacientes com CMD idiopática. Métodos: Um total de 1.025 pacientes com CMD idiopática foram incluídos retrospectivamente e divididos em três grupos com base nos escores de ALBI: grau 1 (≤ −2,60, n = 113), grau 2 (−2,60 a −1,39, n = 835) e grau 3 (> −1,39, n = 77). Foi analisada a associação do escore ALBI com eventos clínicos adversos maiores (ECAM) intra-hospitalares e mortalidade a longo prazo. Valor de p inferior a 0,05 foi considerado estatisticamente significativo. Resultados: A taxa de ECAM intra-hospitalares foi significativamente maior nos pacientes com grau 3 (2,7% versus 7,1% versus 24,7%, p < 0,001). A análise multivariada mostrou que o escore ALBI foi um preditor independente para ECAM intra-hospitalares (odds ratio ajustada = 2,80, IC 95%: 1,63 - 4,80, p < 0,001). Após seguimento mediano de 27 meses, 146 (14,2%) pacientes morreram. A curva de Kaplan-Meier indicou que a taxa cumulativa de sobrevida a longo prazo foi significativamente menor em pacientes com grau mais alto de ALBI (log-rank = 45,50, p < 0,001). O escore ALBI foi independentemente associado à mortalidade a longo prazo (hazard ratio ajustada = 2,84, IC 95%: 1,95 - 4,13, p < 0,001). Conclusão: O escore ALBI, como modelo de risco simples, pode ser considerado uma ferramenta de estratificação de risco para pacientes com CMD idiopática.

Abstract Background: Liver dysfunction is a postulated variable for poor prognosis in dilated cardiomyopathy (DCM). Objective: This study aimed to investigate the prognostic value of the albumin-bilirubin (ALBI) score, a relatively new model for evaluating liver function, in patients with idiopathic DCM. Methods: A total of 1025 patients with idiopathic DCM were retrospectively included and divided into three groups based on ALBI scores: grade 1 (≤ −2.60, n = 113), grade 2 (−2.60 to −1.39, n = 835), and grade 3 (> −1.39, n = 77). The association of ALBI score with in-hospital major adverse clinical events (MACEs) and long-term mortality was analyzed. P-value less than 0.05 was considered statistically significant. Results: The in-hospital MACEs rate was significantly higher in the grade 3 patients (2.7% versus 7.1% versus 24.7%, p < 0.001). Multivariate analysis showed that ALBI score was an independent predictor for in-hospital MACEs (adjusted odds ratio = 2.80, 95%CI: 1.63 - 4.80, p < 0.001). After a median 27-month follow-up, 146 (14.2%) patients died. The Kaplan-Meier curve indicated that the cumulative rate of long-term survival was significantly lower in patients with higher ALBI grade (log-rank = 45.50, p < 0.001). ALBI score was independently associated with long-term mortality (adjusted hazard ratio = 2.84, 95%CI: 1.95 - 4.13, p < 0.001). Conclusion: ALBI score as a simple risk model could be considered a risk-stratifying tool for patients with idiopathic DCM.

Choice of digestive tract reconstruction in upper gastric cancer / 中华胃肠外科杂志

With the increasing incidence of upper gastric cancer and early gastric cancer, surgeons have gradually paid attention to the selection of appropriate digestive tract reconstruction methods. At present, the safety of surgery is no longer the main aim pursued by surgeons, and the focus of surgery has gradually changed to postoperative quality of life. Surgical procedures for upper gastric cancer include total gastrectomy (TG) and proximal gastrectomy (PG). Roux-en-Y anastomosis is recommended for digestive tract reconstruction after TG. The classic method of digestive tract reconstruction after PG is distal residual stomach and esophageal anastomosis. However, to prevent esophageal reflux caused by PG, a lot of explorations have been carried out over the years, including tubular gastroesophageal anastomosis, double-flap technique (Kamikawa anastomosis), interposition jejunum, double-tract reconstruction and so on. But the appropriate method of digestive tract reconstruction for upper gastric cancer is still controversial. In this paper, based on literatures and our clinical experience, the selection, surgical difficulties and techniques of digestive tract reconstruction after PG are discussed.

TSPAN8 is involved in lipid metabolism in non-alcoholic fatty liver disease in mice / 南方医科大学学报

OBJECTIVE@#To investigate the changes of tetraspanin 8 (TSPAN8) expression levels and its role in lipid metabolism during the development of non-alcoholic fatty liver disease (NAFLD).@*METHODS@#Thirty male C57BL/6J mice were randomly divided into normal diet group and high-fat diet (HFD) group (n=15), and after feeding for 1, 3, and 6 months, the expression levels of TSPAN8 in the liver tissues of the mice were detected with Western blotting. In a HepG2 cell model of NAFLD induced by free fatty acids (FFA), the effect of TSPAN8 overexpression on lipid accumulation was examined using Oil Red O staining and an automated biochemical analyzer, and the mRNA expressions of the key genes involved in lipid metabolism were detected using qRT-PCR.@*RESULTS@#Western blotting showed that compared with that in mice with normal feeding, the expression of TSPAN8 was significantly decreased in the liver tissues of mice with HFD feeding for 3 and 6 months (P < 0.05). In HepG2 cells, treatment with FFA significantly decreased the expression of TSPAN8 at both the mRNA and protein levels (P < 0.01). TSPAN8 overexpression in FFA-treated cells showed significantly lowered intracellular triglyceride levels (P < 0.001) and obviously reduced mRNA expression of fatty acid transport protein 5 (FATP5) (P < 0.01). The expression of FATP5 was significantly increased in FFA-treated cells as compared with the control cells (P < 0.001).@*CONCLUSION@#TSPAN8 is involved in lipid metabolism in NAFLD, and overexpression of TSPAN8 may inhibit cellular lipid deposition by reducing the expression of FATP5.

Abnormal Dynamic Functional Connectivity of the Left Rostral Hippocampus in Predicting Antidepressant Efficacy in Major Depressive Disorder

Objective@#Some pharmacological treatments are ineffective in parts of patients with major depressive disorder (MDD), hence this needs prediction of effective treatment responses. The study aims to examine the relationship between dynamic functional connectivity (dFC) of the hippocampal subregion and antidepressant improvement of MDD patients and to estimate the capability of dFC to predict antidepressant efficacy. @*Methods@#The data were from 70 MDD patients and 43 healthy controls (HC); the dFC of hippocampal subregions was estimated by sliding-window approach based on resting-state functional magnetic resonance imaging (R-fMRI). After 3 months treatment, 36 patients underwent second R-fMRI scan and were then divided into the response group and non-response group according to clinical responses. @*Results@#The result manifested that MDD patients exhibited lower mean dFC of the left rostral hippocampus (rHipp.l) compared with HC. After 3 months therapy, the response group showed lower dFC of rHipp.l compared with the non-response group. The dFC of rHipp.l was also negatively correlated with the reduction rate of Hamilton Depression Rating Scale. @*Conclusion@#These findings highlighted the importance of rHipp in MDD from the dFC perspective. Detection and estimation of these changes might demonstrate helpful for comprehending the pathophysiological mechanism and for assessment of treatment reaction of MDD.

Prostate cancer with lymph node metastasis in anterior prostatic fat: a case report / 中华泌尿外科杂志

Lymphatic metastasis is commonly encountered in prostate cancer. However, prostate cancer along with lymph node involvement in anterior prostatic fat is rarely reported. Here we present one case. Lymphadenectasis was noticed during robot-assisted laparoscopic radical prostatectomy. Histopathologic examinations confirmed lymph node metastasis in anterior prostatic fat. The patient was assigned to adjuvant androgen deprivation therapy. At 16-month follow-up, biochemical recurrence has not occurred. Detection of lymph node metastasis in anterior prostatic fat of prostate cancer patients provides valuable information for adequate postoperative staging and management.

Clinical observation of adjusting middle urethral sling tension through anatomic position during RMUS / 中华泌尿外科杂志

Objective:To investigate the safety and effectiveness of tension adjustment technique using anatomical landmarks during retropubic midurethral synthetic sling.Methods:The data of 36 consecutive female patients with urinary incontinence, who had underwent retropubic midurethral synthetic sling procedure from January to August 2019 were analyzed retrospectively. The mean age was (60.83±7.93) years old and the body mass index was (24.43±2.44) kg/m 2. Among the recruited subjects, 36 had positive stress test and Marshall-Marchetti test. 20 (55.6%) were pure stress urinary incontinence, and 16 (44.4%) were mixed urinary incontinence. The severity of incontinence was classified into mild (5 cases, 13.9%), moderate (14 cases, 38.9%), severe (13 cases, 36.1%) and very severe (4 cases, 11.1%) using one-hour pad tests. Urodynamics were performed in 17 cases, with 5 (29.4%) presented detrusor overactivity, 3 (17.7%) possessed intrinsic sphincter deficiency. For each case, the tension of the sling was adjusted based on the anatomical landmarks, i. e. using an angled clamp attached closely to the pubic symphysis ventrally and the tip parallel to the edge of hymen dorsally. All patients were catheter-free right after the procedure. The subjective and objective effectiveness, and safety (the rate of urinary retension after surgery and postvoid residual volume 3 months later) were evaluated.The subjective cure rate was was defined as complete leakage free or very mild leakage during excessive bladder filling and fierce cough. The subjective effectiveness was defined as over 50% improvement of the leakage symptom. The objective cure rate was defined as a negative stress test. Results:For all 36 patients, the median hospital stays was 8 (5-95)h. No bladder perforation or transfusion cases. All patients were catheter-free right after the procedure, with no incidence of urinary retention. 27 patients completed a 3-month follow-up, with 22 had post-void residual data, 23 had subjective effectiveness data and 23 had objective effectiveness data. The median post-void residual was 7.5 (5-64) ml, subjective cure rate was 91.3% (21/23), and objective cure rate was 95.7% (22/23). 8.7% (2/23) reported difficult urination alleviated without the necessity of clinical interference. No urethra erosion or vagina extrusion was found. At 2-year follow-up, 34 patients completed assessment by phone. The subjective cure rate was 91.2% (31/34), with only 2.9% (1/34) reported difficult urination. Besides, at 3-month follow-up, there was no difference regarding the subjective cure rate [100.0%(12/12) vs. 81.8%(9/11)]or objective cure rate [91.7%(11/12) vs. 100.0%(11/11)] between patients with stress and mixed incontinence. No difference was noted among patients with mild, moderate, severe and very severe leakage[75.0% (3/4) vs. 100.0%(6/6) vs. 90.0%(9/10) vs. 100.0%(3/3)]. Of the 12 cases with urodynamic records, the presence of detrusor overactivity [66.7%(2/3) vs. 88.9%(8/9)] or intrinsic sphincter deficiency [0(0/1) vs. 90.9%(10/11)] did not significantly affected the cure rate of the procedure. At 2-year follow-up, there was no difference regarding the subjective cure rate between patients with stress and mixed incontinence [94.7%(18/19) vs. 86.7%(13/15)]. No difference was also noted among patients with mild, moderate, severe and very severe leakage[80.0%(4/5) vs. 100.0%(13/13) vs. 83.3%(10/12) vs. 100.0%(4/4)]. Of the 16 cases with urodynamic records, the presence of detrusor overactivity [60.0%(3/5) vs. 90.9%(10/11)]or intrinsic sphincter deficiency [66.7%(2/3) vs. 84.6%(11/13)]did not significantly affected the cure rate of the procedure.Conclusions:Tension adjustment using anatomic landmarks during sling procedure is safe and feasible for urinary incontinence, with minimum complications and residual volume, and high subjective/objective cure rate.

Targeted therapy for small cell carcinoma of prostate: a case report / 中华泌尿外科杂志

A patient aged 68 years old presented urinary frequency, urgency, and gross hematuria for 1 month, with initial PSA of 72.72 ng/ml and alkaline phosphatase (ALP)of 114 U/L. Prostate biopsy pathology showed small cell neuroendocrine carcinoma of prostate. The patient was immediately administered 6 cycle of chemotherapy including etoposide and cisplatin combined with medical castration. The CDK4 gene was detected 1.99 times amplification by peripheral blood free DNA (cfDNA)gene analysis. The chemotherapy was followed by parbosini therapy. The number and density of bone metastases continued to decrease significantly by bone scan at 3 and 6 months after treatment, with a continuous decline of ALP and PSA. After 1 year of follow-up, pelvic MRI and bone systemic imaging indicated stable lesions, with PSA of 0.05 ng/ml and ALP of 59 U/L.

A multicenter retrospective study of immunotherapy for metastatic renal cell carcinoma / 中华泌尿外科杂志

Objective:To evaluate the efficacy and side effects of PD-1 monoclonal antibody in the treatment of advanced metastatic renal cell carcinoma in China.Methods:The clinical data of 117 patients with advanced metastatic renal cell carcinoma (mRCC) treated with PD-1 monoclonal antibody from October 2016 to February 2022 were retrospectively analyzed. There were 87 males (74.4%) and 30 females (25.6%), with an average age of (57.9±10.9) years old, BMI of (23.6±3.4) kg/m 2and smoking history of 79 (67.5%). There were 44 cases (37.6%) with hypertension, 19 (16.2%) cases of diabetes. The ECOG score of 59.8% (70/117) patients was 0, 33.3% (39/117) was 1, 4.3% (5/117) was 2, and 2.5% (3/117) was 3. The pathological type of 104 cases were renal clear cell carcinoma (ccRCC), 8 cases of papillary renal cell carcinoma, 2 cases of chromophobe cell carcinoma, 2 cases of collecting duct carcinoma and 1 case of eosinophilic cell carcinoma. The general condition of the overall population and the overall survival (OS) of relevant subgroups were analyzed. Secondary goals included progression free survival (PFS), objective response rate (ORR), adverse reactions, overall survival (OS), and progression free survival (PFS). Results:65.8% (77 / 117) of the patients chose targeted combined with PD-1 monoclonal antibody in the first-line treatment. The main targeted drugs were acitinib (81.8%, 63 / 77), tirelizumab (37.6%, 29 / 77) and cindilimab (25.9%, 20 / 77). After first-line treatment, 19.6.1% (23 / 117) patients needed to be converted to second-line treatment, and 15 patients changed the type of PD-1 antibody during treatment. In addition, the targeted drug of combined therapy was replaced by acitinib in 8 patients. The main causes of drug withdrawal were disease progression (70.7%, 29 / 41) and death (29.2%, 12 / 41). The median OS of the overall population was 35.6 (19-60) months and PFS was 12.1 (1-60) months. The ORR of the overall population was 47.8% (56 / 117). 4.2% (5/117) patients had complete remission, another 17.0% (20/117) patients were in stable condition, and 43.5% (51 / 117) patients were in partial remission. In the first-line treatment, the median PFS time of targeted combined with PD-1 monoclonal antibody was 12.6 (1-30) months, the median PFS time of PD-1 single drug immunotherapy was 10.5 (1-60) months. In the second-line treatment, the PFS of patients treated with PD-1 monoclonal antibody was 10.1 (4-19) months, and that of patients treated with PD-1 monoclonal antibody combined with targeted therapy was 11.7 (1-25) months. The most common adverse reactions were elevated blood pressure (18.5%, 23 / 124), followed by hypothyroidism (15.3%%, 19/124), rash (14.5%, 18 / 124), elevated transaminase (10.5%, 13 / 124) and bone marrow suppression (9.7%, 12/124). 9.4% (11 / 117) patients needed to reduce the related adverse reactions by interrupting the treatment control of PD-1 monoclonal antibody.Conclusions:The safety and efficacy of PD-1 monoclonal antibody in domestic patients are better, and the side effects are less. The efficacy and safety of PD-1 monoclonal antibody combined with targeted therapy in the real world population are consistent with many key clinical trials abroad. PD-1 monoclonal antibody combined with targeted drugs can be popularized in the domestic MRCC population.
