ABSTRACT

Objective:To investigate the protective effects and related mechanisms of Astragaloside Ⅳ(ASⅣ)alleviating Angiotensin II-induced cardiomyocyte hypertrophy.Methods:H9c2 cardiomyocytes were divided into six groups: normal control group, ASⅣ group(ASⅣ 100 μmol/L), AngⅡ group(AngⅡ 1 μmol/L), and three ASⅣ dose experiments(AngⅡ 1 μmol/L + ASⅣ 25 μmol/l group, AngⅡ 1 μmol/L+ ASⅣ 50 μmol/l group, AngⅡ1 μmol/L+ ASⅣ 100 μmol/L group), and simultaneously cultured for 24 hours.Cardiomyocyte viability was assessed by CCK8 assay, and surface area of culturedcardiomyocytes in each group was assessed by immunofluorescence assay.Atrial natriuretic peptide(ANP)mRNA expression was assessed by fluorescence real-time quantitative RT-PCR.And LC3 protein expression, an autophagy related protein, was assessed by Western blotting as well as immunofluorescence.Results:(1)AngⅡ decreased cardiomyocyte H9c2 viability in a dose-dependent manner( P<0.05). ASⅣ could inhibit the decrease of cardiomyocyte H9c2 viability in response to AngⅡ in a dose-dependent manner( P<0.05). (2)H9c2 cardiomyocytes induced by AngⅡ showed a significantly larger cell area and significantly higher ANP mRNA and ANP protein expression compared with controls.Different concentrations of ASⅣ intervention could reverse the increase of cardiomyocyte H9c2 area induced by AngⅡ and also decreased the expression of ANP protein induced by AngⅡ in a dose-dependent manner(all P<0.05). (3)Compared with the control group, the autophagy level and the expression of autophagy marker LC3II/I of H9c2 cardiomyocytes induced by AngⅡ were significantly increased(all P<0.05). ASⅣ could inhibit AngⅡ-activated autophagy, and the difference was statistically significant( P<0.05). ASⅣ inhibited the expression of LC3II/I in H9c2 cardiomyocytes stimulated by AngⅡ, and the difference was statistically significant( P<0.05). Conclusions:ASⅣ inhibits AngⅡ-induced cardiac hypertrophy by inhibiting autophagy of cardiomyocytes.

ABSTRACT

ObjectiveTo investigate the inhibitory effect of hederasaponin B on gastric cancer HGC-27 cell and the mechanism. MethodMethyl thiazolyl tetrazolium (MTT) assay, hematoxylin-eosin (HE) staining, 4',6-diamidino-2-phenylindote (DAPI) staining, colony formation assay, scratch assay, and flow cytometry were employed for the analysis of apoptosis and cell cycle. Thereby, the inhibitory effect of hederasaponin B on gastric cancer HGC-27 cell was investigated. Then the Pharm Mapper, UniProt, Swissdock, STRING, and Metascape were used for target screening, gene annotation, molecular docking, protein-protein interaction (PPI) network construction, Gene Ontology (GO) term and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis to explore the mechanism. ResultHederasaponin B (15, 30, 60, 120 μmol·L-1) can significantly reduce the survival rate of HGC-27 cell (P<0.01) in a time-dependent and dose-dependent manner compared with the blank group. It had no significant toxicity to normal GES-1 cell at concentration below 120 μmol·L-1. Compared with the blank group, hederasaponin B (30, 60, 120 μmol·L-1) induced cytoplasmic vacuolization, and nuclear deformation and karyopyknosis, inhibited the migration of HGC-27 cell (P<0.01), and brought about the apoptosis (P<0.05, P<0.01) and cell cycle arrest of HGC-27 cell (P<0.05, P<0.01). Hederasaponin B (10, 20, 30 μmol·L-1) also suppressed the independent survival ability and proliferation ability of HGC-27 cell (P<0.01). The possible action targets were kinesin-like protein KIF11, cGMP-specific 3,5 cyclic phosphodiesterase, caspase-3, serine/threonine protein kinase Chk1, proto-oncogene tyrosine protein kinase, epidermal growth factor receptor, and mitogen-activated protein kinase (MAPK) 8. The mechanism may be related to MAPK signaling pathway (pathways in cancer), adhesion connection, focal adhesion and proteoglycans in cancer (epithelial cell signaling pathways in Helicobacter pylori infection). ConclusionHederasaponin B exerts significant inhibitory effect on gastric cancer HGC-27 cell through multiple targets and multiple pathways.

ABSTRACT

Tumor microenvironment (TME) is a dynamic network distributed around tumor cells. Cancer-associated fibroblasts (CAFs), as an important component of the TME, are not only closely related to normal fibroblasts, but also can secrete a variety of substances to participate in the regulation of the TME. Exosomes, one of the substances from CAFs, can promote the formation and development of lung cancer, including promoting the formation of TME, increasing pulmonary tumor cell invasion and metastasis, mediating pulmonary tumor immunosuppression and participating in radiotherapy and chemotherapy resistance. This article reviews the current research status and progress of cancer associated fibroblasts-derived exosomes in lung cancer.

ABSTRACT

The incidence rate of lung cancer is one of the highest incidence of malignancies in China. The gold standard for diagnosis requires pathological examination or cytological examination of biopsy. The invasive and sensitive nature of the two limits their use. Sputum contains a large number of nucleic acids and proteins, which is a good reflection of lung function. Lung cancer tissue will also affect the biological components in sputum. The detection of bioactive substances in sputum can contribute to the diagnosis of lung cancer. Based on the current research results at home and abroad, this paper reviews the bioactive substances in sputum that can be used for the diagnosis of lung cancer.

ABSTRACT

OBJECTIVE@#To evaluate urinary continence recovery time and risk factors of urinary continence recovery after robot-assisted laparoscopic radical prostatectomy (RARP).@*METHODS@#From January 2019 to January 2021, a consecutive series of patients with localized prostate cancer (cT1-T3, cN0, cM0) were prospectively collected. RARP with total anatomical reconstruction was performed in all the cases by an experienced surgeon. Lymph node dissection was performed if the patient was in high-risk group according to the D'Amico risk classification. The primary endpoint was urinary continence recovery time after catheter removal. Postoperative and pathological variables were analyzed. Continence was rigo-rously analyzed 48 hours, 1 week, 4 weeks, 12 weeks, and 24 weeks after catheter removal. Continence was evaluated by recording diaper pads used per day, and all the patients were instructed to perform the 24-hour pad weight test until full recovery of urinary continence. The patient was defined as continent if no more than one safety pad were needed per day, or no more than 20-gram urine leakage on the 24-hour pad weight test. Time from catheter removal to full recovery of urinary continence was recorded, and risk factors influencing continence recovery time evaluated.@*RESULTS@#In total, 166 patients were analyzed. The mean age of the enrolled patients was 66.2 years, and the median prostate specific antigen (PSA) was 8.51 μg/L. A total of 59 patients (35.5%) had bilateral lymphatic dissection, and 28 (16.9%) underwent neurovascular bundle (NVB) preservation surgery. Postoperative pathology results showed that stage pT1 in 1 case (0.6%), stage pT2 in 77 cases (46.4%), stage pT3 in 86 cases (51.8%), and positive margins in 28 patients (16.9%). Among patients who underwent lymph node dissection, lymph node metastasis was found in 7 cases (11.9%). Median continence recovery time was one week. The number of the continent patients at the end of 48 hours, 1 week, 4 weeks, 12 weeks, and 24 weeks were 65 (39.2%), 32 (19.3%), 34 (20.5%), 24 (14.5%), and 9 (5.4%). Two patients remained incontinent 24 weeks after catheter removal. The continence rates after catheter removal at the end of 48 hours, 1 week, 4 weeks, 12 weeks, and 24 weeks were 39.2%, 58.4%, 78.9%, 93.4%, and 98.8%, respectively. Univariate COX analysis revealed that diabetes appeared to influence continence recovery time (OR=1.589, 95%CI: 1.025-2.462, P=0.038). At the end of 48 hours, 4 weeks, 12 weeks, and 24 weeks after catheter removal, the mean OABSS score of the continent group was significantly lower than that of the incontinent group.@*CONCLUSION@#RARP showed promising results in the recovery of urinary continence. Diabetes was a risk factor influencing continence recovery time. Bladder overactive symptoms play an important role in the recovery of continence after RARP.

ABSTRACT

Objective:To evaluate the feasibility, safety and efficacy of the magnetic resonance imaging guided focused ultrasound surgery (MRgFUS) in the treatment of localized prostate cancer (PCa).Methods:The data of 5 patients treated by MRgFUS from August 2020 to June 2021 in our institution were retrospectively analyzed. The median age was 73 (58-80) years, with the median PSA of 7.34 (5.19-8.40) ng/ml, and a median prostate volume of 27.96 (21.50-37.91) ml. The median pretreatment international prostate symptom score (IPSS) was 13(0-18). Of the 3 patients with intention of erectile function preservation, the pretreatment international index of erectile function-15 (IIEF-15) score was 12, 23 and 3, respectively. All patients had histopathology-proven PCa of grade group ≤ International Society of Urological Pathology (ISUP) 3, pre-operative PSA level <20 ng/ml, and a clinical stage ≤T 2b. A total of 6 lesions was confirmed by biopsy, with 3 of ISUP grade group 3 and 3 of ISUP grade group 1. All 5 patients underwent MRgFUS which was guided by a real-time magnetic resonance imaging (MRI). PSA, MRI and repeated biopsy were conducted to monitor recurrence. Questionnaires consisted of IPSS, IIEF-15, and the International Consultation on Incontinence-questionnaire-Short Form (ICI-Q-SF) were recorded before and after MRgFUS to evaluate the impact on functional preservation. Results:A total of 5 patients received MRgFUS. In total, 5 of the 6 lesions were treated. 1 lesion unvisible on MRI was not clinically significant and was left untreated. The median time in MRI scanner was 190 (140-355) min, and the median sonication time was 64 (35-148) min with the median sonications of 8 (5-13). The median catheter indwelling time was 1 (1-8) days. No other adverse effects were reported. The PSA level of all 5 patients decreased, with the nadir PSA of 1.196 ng/ml, 4.398 ng/ml, 4.135 ng/ml, 1.562ng/ml and 1.350ng/ml, respectively. 4 of the patients had a PSA decrease over 50%. No PCa lesion was seen on MRI at 3-month follow-up visit. As for functional preservation, the post-MRgFUS IPSS declined compared with the baseline score, and the IPSS of last follow-up was 5(0-14). Of the 3 patients with intention to preserve the erectile function, the erectile function score of IIEF-15 were 12, 30 and 9 three months after the treatment, respectively. No incontinence occurred postoperatively.Conclusions:MRgFUS is a feasible and safe way for the treatment of low- to intermediate-risk localized PCa, with satisfactory performance on functional preservation and low incidence of complications. The oncological outcomes still need to be establised with longer follow-up time and larger sample studies.

ABSTRACT

Objective:To evaluate the risk factors of clinical cure and biochemical recurrence (BCR) after radical prostatectomy (RP).Methods:The clinical data of 896 patients who underwent RP at Peking University First Hospital from April 2001 to December 2020 were retrospectively analyzed. Average age was (65.90±6.3) years, median preoperative prostate specific antigen (PSA) was 10.75 (0.36-264.20) ng/ml, median prostate volume was 40.0 (12.0-220.9) ml, median PSA density (PSAD) was 0.27 (0.02-3.42) ng/(ml·g). Clinical staging: 432 cases in T 1c stage, 333 cases in T 2a/bstage, 76 cases in T 2c stage, and 55 cases in ≥T 3 stage. Preoperative Gleason score of biopsy: 193 cases in 3+ 3, 315 cases in 3+ 4, 162 cases in 4+ 3, 226 cases in ≥8. The RP surgery was operated by open or laparoscopic or robot-assisted approach. Clinical cure and BCR were used as the end points for analysis. Clinical cure was defined as a decrease in serum PSA level below 0.03 ng/ml 6 weeks after surgery. BCR was defined as the 2 consecutive serum PSA >0.2ng/ml during the follow-up after RP. Multivariate logistic regression was used to analyze the independent risk factors of clinical cure. The Kaplan-Meier method was used to draw the biochemical recurrence-free survival curve, the log-rank method was used for univariate analysis of BCR, and the Cox regression analysis was used for multivariate analysis. Results:All 896 patients were followed-up for 58 (5-241) months, 678 cases (75.7%) achieved clinical cure. Based on univariate analysis and multivariate analysis, among the preoperative indicators, whether the proportion of positive biopsy needles ≥33% ( P=0.007) and preoperative Gleason score of biopsy ( P=0.041) were independent risk factors of clinical cure. A total of 890 cases were included in the analysis of risk factors of BCR, of whom 172 cases (19.3%) had BCR. The 1-, 5-, and 10-year biochemical recurrence-free survival(BFS)rates were 98.1%, 83.1% and 68.4% respectively. The median BFS has not been reached, and the average BFS was 181 months (95% CI 172-189). The results of univariate and multivariate analysis showed that whether achieved clinical cure ( P=0.001) and postoperative pathological staging ( P<0.001) were independent risk factors of BCR. Conclusions:Whether the proportion of positive biopsy needles≥33% and preoperative Gleason score of biopsy were independent risk factors of clinical cure. Postoperative pathological staging and whether achieved clinical cure may be independent risk factors of BCR.

ABSTRACT

The good results of enhanced recovery after surgery (ERAS) combined with minimally invasive surgery are reflected in reducing the incidence of perioperative complications and shortening the length of hospitalization (LOS). It has been widely used in surgical fields of different specialties. The implementation of the day surgery mode can shorten the waiting time for patients and reduce the financial burden. Especially in thoracic surgery, the shorter the waiting time in the hospital, the more beneficial for the patient's physical and psychological recovery. With the widespread implementation of minimally invasive technology and accelerated rehabilitation procedures, the application of ERAS in thoracic surgery has made it possible for some thoracic surgery to be completed in the day surgery. This article summarizes the current application of ERAS in the field of thoracic surgery and the development prospects of day surgery models in China.

ABSTRACT

Objective:To summarize the experience of robotic and thoracoscopic segmentectomy in Daping Hospital, Army Medical University, and comparison analysis the clinical application value for early-stage lung cancer.Methods:A retrospective cohort study was conducted to continuously enroll 190 patients, 100 who received robotic(33 males and 67 females, median age of 51 years)and 90 who received VATS(34 males and 56 females, median age of 54 years), who underwent segmentectomy between June 2018 and October 2019. Perioperative outcomes(the operation time, intraoperative blood loss, postoperative thoracic drainage volume and time, pain score, complications, postoperative hospital stay and survival and mortality) were compared.Results:All the patients successfully completed the surgery and recovered from hospital, with no perioperative death.The baseline characteristics(sex, age, clinical symptoms, smoking status, underlying disease, tumor size, pathological type) and type of segmentectomy were comparable. There was significant difference in operative time[120(interquartile range, IQR 60-225)min vs. 155( IQR 75-330)min, P<0.001], blood loss[30( IQR 20-400) ml vs. 100( IQR 20-1 600) ml, P<0.001] between the robotic and VATS groups, respectively. But there was no significant difference in postoperative thoracic drainagevolume[4( IQR 1-15) days vs. 4( IQR 2-29) days, P=0.547], postoperative thoracic time[755( IQR 200-3 980)ml vs. 815( IQR 280-3 920)ml, P=0.902], pain score[2.33( IQR 0.88-4.75) points vs. 3.13( IQR 0.95-5.29)points, P=0.199], complications[7.4%(14/190) vs. 6.3%(12/190), P=0.303], postoperative hospital stay[7( IQR 3-19) days vs. 6( IQR 4-21) days, P=0.405] , number of lymph nodes[(4.83±3.18) vs.(6.15±4.1), P=0.255] between the robotic and VATS groups, respectively. The follow-up time was 6.5( IQR 1-26) months in the two groups, without recurrence, metastasis or death. Conclusion:Robotic lung segmentectomy is safe and feasible. This approach might lead to a better in operative time and blood loss. The short-term efficacy is similar with thoracoscopy, and the long-term efficacy needs further follow-up time.

ABSTRACT

Propolis is a bee wax rich in various phytocomponents and traditionally used to treat various ailments. Propolis is reported to possess an array of biological properties including anti-inflammatory, antioxidant, anti-cancer, and anti-diabetic as well as cardioprotective, hepatoprotective, renoprotective, and derma protective activities. A plethora of studies confirmed that propolis is effective against various types of cancer including head and neck, lung, liver, brain (glioma), pancreas, kidney, prostate, skin (melanoma), breast, oral, esophagus, gastric, colorectal, and bladder cancers. However, many researchers have demonstrated that propolis displays potent chemoprotective/chemopreventive or anti-cancer activity against only a few types of cancers like oral, gastrointestinal, dermal (melanoma), breast, and prostate cancers. Therefore, this mini-review only summarizes the chemopreventive/chemotherapeutic activities of propolis and its updated underlying mechanisms. Taken together, propolis displays potent chemoprotective or anti-cancer effect due to the presence of various phytocomponents which contribute to pro-apoptotic, cytotoxic, anti-proliferative (cell cycle arrest), anti-metastatic, anti-invasive, anti-angiogenic and anti-genotoxic or anti-mutagenic properties along with antioxidant, immunomodulatory, and anti-inflammatory functions. Hence, propolis could be used as an adjuvant for treating various cancers along with standard chemotherapeutic drugs. However, many large-scale clinical studies are needed to justify such applications.

ABSTRACT

@#Objective    To explore the clinical value of three-dimensional computed tomography bronchography and angiography (3D-CTBA) in robotic lung segmentectomy. Methods    A non-randomized control study was performed and continuously enrolled 122 patients who underwent robotic lung segmentectomy in our hospital from January 2019 to January 2020. 3D-CTBA was performed before operations in 53 patients [a 3D-CTBA group, including 18 males, 35 females, with a median age of 52 (26-69) years] and not performed in the other 69 patients [a traditional group, including 23 males, 46 females, with a median age of 48 (30-76) years]. The clinical data of the patients were compared between the two groups. Results    All the patients were successfully completed the surgery and recovered from hospital, with no perioperative death. The baseline characteristics of the patients were not significantly different between the two groups (P>0.05). No significant difference was found in the operative time [120 (70-185) min vs. 120 (45-225) min, P=0.801], blood loss [50 (20-300) mL vs. 30 (20-400) mL, P=0.778], complications rate (17.0% vs. 11.6%, P=0.162), postoperative hospital stay [7 (4-19) d vs. 7 (3-20) d, P=0.388] between the two groups. In the 3D-CTBA group, 5 (9.4%) patients did not find nodules after segmentectomy, and only 1 (1.9%) of them needed lobectomy, but in the traditional group, 8 (11.6%) patients did not find nodules and had to carry out lobectomy, the difference was statistically significant (P<0.05). The follow-up time was 10 (1-26) months, and during this period, there was no recurrence, metastasis or death in the two groups. Conclusion    3D-CTBA is helpful for accurate localization of nodules and reasonable surgical planning before operations, and reducing wrong resections in segmentectomy, without increasing the operation time, blood loss and complications. It is safe and effective in anatomical lung segmentectomy.

ABSTRACT

BACKGROUND@#Cardiac remodeling after acute myocardial infarction (AMI) is an important process. The present study aimed to assess the protective effects of astaxanthin (ASX) on cardiac remodeling after AMI.@*METHODS@#The study was conducted between April and September 2018. To create a rat AMI model, rats were anesthetized, and the left anterior descending coronary artery was ligated. The rats in the ASX group received 10 mg·kg·day ASX by gavage for 28 days. On the 1st day after AMI, but before ASX administration, six rats from each group were sacrificed to evaluate changes in the heart function and peripheral blood (PB) levels of inflammatory factors. On the 7th day after AMI, eight rats from each group were sacrificed to evaluate the PB levels of inflammatory factors and the M2 macrophage count using both immunofluorescence (IF) and flow cytometry (FC). The remaining rats were observed for 28 days. Cardiac function was examined using echocardiography. The inflammatory factors, namely, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-10, were assessed using enzyme-linked immunosorbent assay. The heart weight/body weight (BW), and lung weight (LW)/BW ratios were calculated, and myocardial fibrosis in the form of collagen volume fraction was measured using Masson trichrome staining. Hematoxylin and eosin (H&E) staining was used to determine the myocardial infarct size (MIS), and TdT-mediated dUTP nick-end labeling staining was used to analyze the myocardial apoptosis index. The levels of apoptosis-related protein, type I/III collagen, transforming growth factor β1 (TGF-β1), metalloproteinase 9 (MMP9), and caspase 3 were assessed by Western blotting. Unpaired t-test, one-way analysis of variance, and non-parametric Mann-Whitney test were used to analyze the data.@*RESULTS@#On day 1, cardiac function was worse in the ASX group than in the sham group (left ventricular end-systolic diameter [LVIDs]: 0.72 ± 0.08 vs. 0.22 ± 0.06 cm, t = -11.38; left ventricular end-diastolic diameter [LVIDd]: 0.89 ± 0.09 vs. 0.48 ± 0.05 cm, t = -9.42; end-systolic volume [ESV]: 0.80 [0.62, 0.94] vs. 0.04 [0.03, 0.05] mL, Z = -2.89; end-diastolic volume [EDV]: 1.39 [1.03, 1.49] vs. 0.28 [0.22, 0.32] mL, Z = -2.88; ejection fraction [EF]: 0.40 ± 0.04 vs. 0.86 ± 0.05, t = 10.00; left ventricular fractional shortening [FS] rate: 0.19 [0.18, 0.20] %FS vs. 0.51 [0.44, 0.58] %FS, Z = -2.88, all P < 0.01; n = 6). The levels of inflammatory factors significantly increased (TNF-α: 197.60 [133.89, 237.94] vs. 50.48 [47.21 57.10] pg/mL, Z = -2.88; IL-1β: 175.23 [160.74, 215.09] vs. 17.78 [16.83, 19.56] pg/mL, Z = -2.88; IL-10: 67.64 [58.90, 71.46] vs. 12.33 [11.64, 13.98] pg/mL, Z = -2.88, all P < 0.01; n = 6). On day 7, the levels of TNF-α and IL-1β were markedly lower in the ASX group than in the AMI group (TNF-α: 71.70 [68.60, 76.00] vs. 118.07 [106.92, 169.08] pg/mL, F = 42.64; IL-1β: 59.90 [50.83, 73.78] vs. 151.60 [108.4, 198.36] pg/mL, F = 44.35, all P < 0.01, n = 8).

ABSTRACT

The good results of enhanced recovery after surgery (ERAS) combined with minimally invasive surgery are reflected in reducing the incidence of perioperative complications and shortening the length of hospitalization (LOS). It has been widely used in surgical fields of different specialties. The implementation of the day surgery mode can shorten the waiting time for patients and reduce the financial burden. Especially in thoracic surgery, the shorter the waiting time in the hospital, the more beneficial for the patient's physical and psychological recovery. With the widespread implementation of minimally invasive technology and accelerated rehabilitation procedures, the application of ERAS in thoracic surgery has made it possible for some thoracic surgery to be completed in the day surgery. This article summarizes the current application of ERAS in the field of thoracic surgery and the development prospects of day surgery models in China.

ABSTRACT

The acupuncture and moxibustion of TCM was introduced into Malaysia since fourteenth century. After several centuries of precipitation and accumulation, acupuncture and moxibustion showed vigorous vitality in Malaysia. This article provides an overview of the development of acupuncture in Malaysia from a full-time education in acupuncture, association, policy support for acupuncture, clinical application and scientific research, etc. With the frequent exchanges between the traditional medical community in Malaysia and the Chinese medicine community in mainland China, the spread of acupuncture in Malaysia has been greatly promoted.

ABSTRACT

The good effect of enhanced recovery after surgery is reflected in reducing the incidence of perioperative complications and shortening the hospital stays. However, the concern for the management of perioperative patients and the quality of life of patients after surgery is not high enough. Evaluating clinical efficacy from the perspective of patient-reported data has received increasing attention. Combining the current domestic and foreign research results on the outcome of patient reports, this article systematically discusses the concept connotation, research significance, and clinical application of thoracic surgery for the outcome of patient reports with proposing a clinical outcome research model that draws on foreign patient reports to develop Chinese characteristics. Combine the related research of discipline characteristics, and summarize and analyze the existing literature reports.
