RESUMO

PURPOSE: We aimed to evaluate the safety and efficacy of hyperthermic intraoperative thoraco-abdominal chemotherapy (HITAC) and cytoreductive surgery (CRS) for peritoneal carcinomatosis (PC) patients who underwent diaphragm resection. METHODS: PC patients who underwent CRS with diaphragm resection were selected from a prospectively established database and were divided into hyperthermic intraperitoneal chemotherapy (HIPEC) and HITAC groups. The clinicopathological characteristics, treatment-related variables, perioperative adverse events (AEs), and survival outcomes were compared between the two groups. RESULTS: Of 1168 CRS + HIPEC/HITACs, 102 patients were enrolled-61 HITAC patients and 41 HIPEC patients. In the HITAC and HIPEC groups, the incidence of grade III-V AEs was 29.5% versus 34.1% (p = 0.621). The pleural progression rates were 13.2 versus 18.9% (p = 0.462) and the median overall survival (OS) was 50.5 versus 52.7 months (p = 0.958). Median time to progression (TTP) in thoracic disease was not reached. There was no significant difference in perioperative AEs, TTP, and OS for total patients and the completeness of cytoreduction (CC) score subgroups (p > 0.05). Age ≥ 60 years (hazard ratio [HR] 4.162, p = 0.026) was an independent risk factor influencing pleural progression, and primary malignant peritoneal mesothelioma (MPM; HR 2.749, p = 0.016) and the presence of two or more serious AEs (SAEs; HR 7.294, p = 0.001) were independent risk factors influencing OS. CONCLUSIONS: HITAC can be performed in carefully selected PC patients who underwent diaphragm resection, with no worsening of the safety profile and a possible benefit for pleural progression. In those patients, age ≥ 60 years is associated with a shorter TTP of thoracic disease, while primary MPM and two or more perioperative SAEs are associated with worse OS.

RESUMO

AIM: To evaluate the effect of secondary cytoreductive surgery (SeCRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) in recurrent epithelial ovarian cancer patients. METHODS: This retrospective study analyzed a prospective database. We collected information of 389 patients who were diagnosed with recurrent epithelial ovarian cancer. All patients underwent SeCRS with or without HIPEC. Overall survival and progression-free survival (PFS) were used to evaluate the treatment effectiveness. RESULTS: Of the 389 patients collected, 123 underwent primary or interval cytoreductive surgery at initial treatment and SeCRS at recurrence (Group A), 130 underwent primary or interval cytoreductive surgery at initial and SeCRS plus HIPEC at recurrence (Group B), and 136 underwent primary or interval cytoreductive surgery plus HIPEC at initial and SeCRS plus HIPEC at recurrence (Group C). The median overall survival for Groups A, B, and C were 49.1 months (95% confidence interval [CI]: 47.6-50.5), 56.0 months (95% CI: 54.2-57.7), and 64.4 months (95% CI: 63.1-65.6), respectively. The median PFS for Groups A, B, and C were 13.1 months (95% CI: 12.6-13.5), 15.0 months (95% CI: 14.2-15.7), and 16.8 months (95% CI: 16.1-17.4), respectively. There were no significant difference in incidence and grade of adverse events among groups. CONCLUSIONS: This study suggested that SeCRS plus HIPEC followed by chemotherapy resulted in longer overall survival and PFS than only SeCRS followed by chemotherapy in patients with recurrent ovarian cancer, especially in patients who were treated with repeat HIPEC.

RESUMO

BACKGROUND: Breast cancer (BC) has the highest morbidity and the fifth-highest mortality rate among women in China. Peritoneal metastases from BC are rare, and presently, there are no guidelines or international consensus on its treatment. Patients with a prognosis of peritoneal carcinomatosis (PC) have poorer survival rates than patients with other regional metastases from BC. METHODS: Four BC PC patients, who had undergone cytoreductive surgery (CRS) + hyperthermic intraperitoneal chemotherapy (HIPEC), participated in this study. Clinicopathologic characteristics and overall survival (OS) data were collected and analyzed. RESULTS: Patients' average age when they underwent CRS + HIPEC was 59.8 years. The average time of CRS + HIPEC was 8.8 h. The median number of resected organ areas was 7. Following CRS + HIPEC, each of the 4 patients survived for 31, 28, 16 and 52 months, respectively. There were no serious adverse events during the perioperative period. CONCLUSIONS: The study examined the detailed process of CRS + HIPEC and found that patients with BC PC may benefit from this treatment. The 4 cases provided evidence that the integrated therapy of CRS + HIPEC is a promising strategy that could improve outcomes for BC PC patients. Further, no serious adverse events (SAEs) occurred during the CRS + HIPEC perioperative period.

RESUMO

BACKGROUND: Pleural effusion (PE) is one of the most common complications of advanced recurrent ovarian cancer. However, no studies have revealed the risk factors for PE after surgery. The purpose of this study is to observe the incidence and risk factors of PE after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with late-stage and recurrent ovarian cancer. METHODS: A retrospective analysis of 77 patients with late-stage and recurrent ovarian cancer after CRS + HIPEC was conducted. According to the presence of PE within 7 days after operation, two groups were formed. The basic information, surgical process, and laboratory examinations of the two groups were analyzed and compared to conduct a regression analysis. RESULTS: The incidence of postoperative PE was 57.1% (44/77 patients). Among these patients, the prevalence of grade I-II and grade III-IV PE was 42.8% (33/77 patients) and 14.3% (11/77 patients), respectively. There were statistically significant differences between the two groups in terms of preoperative PE, the duration of surgery, intraoperative blood loss, postoperative level of albumin, intestinal involvement, and diaphragmatic involvement. Among these, preoperative PE and diaphragmatic involvement were identified as independent risk factors of postoperative PE. CONCLUSIONS: Patients with late-stage and recurrent ovarian cancer invariably develop postoperative PE after CRS + HIPEC. Preoperative PE and diaphragmatic involvement are independent risk factors of postoperative PE. It is estimated that the incidence of postoperative PE among patients with these two independent risk factors is approximately 100%. Hence, we should promote the prevention and treatment of PE to improve its prognosis.

RESUMO

BACKGROUND: Wogonoside, an effective component of Scutellaria baicalensis extract, has recently become a hot topic for its newly discovered anticancer efficacy, but the underlying pharmacological mechanism is still unclear. In this study, we tested the inhibitory effects of wogonoside in human prostate cancer PC3 cells in vitro and vivo. METHODS: The effects of wogonoside on cell viability, cycle progression, invasion, migration, and apoptosis were assessed in vitro. The levels of proteins in related signaling pathways were detected by western blotting assay. Finally, nude mouse tumorigenicity assay was conducted to detect the anticancer effect of wogonoside in vivo. RESULTS: Wogonoside inhibited cell viability, invasive and migratory ability in a time- and dose-dependent manner. Flow cytometry indicated that wogonoside could induce cell apoptosis and S phase cell-cycle arrest. Mechanically, wogonoside suppressed the Wnt/ß-catenin signaling pathway, and the level of p-glycogen synthase kinase-3ß (GSK-3ß; Ser9) was inhibited by wogonoside. The epithelial-mesenchymal transition (EMT) process was also reversed in PC3 cell line after wogonoside treatment. In vivo experiments showed that wogonoside inhibited tumor growth in xenograft mouse models. CONCLUSION: These findings revealed that wogonoside could suppress Wnt/ß-catenin pathway and reversing the EMT process in PC3 cells. GSK-3ß acts as a tumor suppressor in prostate cancer. Wogonoside may serve as an effective agent for treating prostate cancer.

RESUMO

BACKGROUND: Treatment of psoriasis is always difficult, which requires intensive scientific research. OBJECTIVE: Tripterygium wilfordii Hook F (TwHF) with acitretin(TwHF + acitretin) is normally used in treating psoriasis. This study aimed to investigate the correlation of plasma miR-126 expression with risk and severity of psoriasis, and its predictive value of response to TwHF + acitretin treatment in psoriasis. METHODS: MiRNA-126(MiR-126) expression in plasma was analyzed in psoriasis patients at month 0 (M0), M1, M3 and M6 and in health controls (HCs) at enrollment by qPCR. Psoriasis-affected body surface area (BSA) and Psoriasis Area and Severity Index (PASI) score were used to assess severity and treatment response. RESULTS: Plasma miR-126 levels were decreased in psoriasis patients compared with HCs (P < 0.001), with area under the curve (AUC) of 0.771. MiR-126 expression was negatively correlated with PASI score (P = 0.001), and negatively associated with psoriasis-affected BSA (P = 0.825). At M6, 65.3% and 36.1% patients achieved PASI 50 and 75, respectively. MiR-126 increased at M1, M3 and M6 after TwHF + acitretin treatment when comparing with M0 (all P < 0.001). Meanwhile, miR-126 expression baseline in PASI 50 group declined when comparing with non-PASI 50 group (P < 0.001). Additionally, data revealed that the cause of high miR-126 baseline level was due to unsuccessfully achieving PASI 50 at M6 after TwHF + acitretin treatment (P < 0.001). However, miR-126 baseline expression was not a predictive factor for PASI 75 achievement (P > 0.05). CONCLUSION: Plasma miR-126 expression is negatively correlated with psoriasis risk and severity, and its high baseline level can be used as a biomarker to predict worse clinical response to TwHF + acitretin treatment in psoriasis.

RESUMO

OBJECTIVE: The purpose of the current work was to comparatively assess 1470 nm diode laser enucleation of the prostate (DiLEP) and plasmakinetic resection of the prostate (PKRP) for treating benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: From January 2016 to March 2017, 157 individuals with bladder outflow obstruction caused by BPH were randomized to DiLEP and PKRP groups, for prospective analysis. Of these, 152 cases were evaluated before operation and at 3, 6, and 12 months postsurgery. Patient baseline properties, presurgery data, and postsurgical outcomes were comparatively assessed, as well as complications. RESULTS: There were no significant preoperative differences between surgical groups. DiLEP-treated cases showed remarkable reduced operative time, postsurgical bladder irrigation time, catheterization duration, and hospital stay compared with the PKRP group (P < 0.001). Hemoglobin amount decrease was markedly less pronounced after DiLEP (P = 0.004). However, no patients needed blood transfusion in either group. The decrease in sodium level showed no marked differences between the DiLEP and PKRP groups (P = 0.380). In addition, complications were comparable and no significant differences in both groups. At 3, 6, and 12 months, International Prostate Symptom Score (IPSS), quality of life (QoL), maximum flow rate (Qmax), and postvoid residual (PVR) were similar in both groups (P > 0.05). CONCLUSIONS: DiLEP and PKRP are similar in efficacy and safety for relieving obstruction and low urinary tract symptoms. Compared with PKRP, DiLEP has decreased risk of hemorrhage, operative time, bladder irrigation time, catheterization duration, and hospital stay. However, IPSS, QoL, Qmax, and PVR were similar for both procedures within 12 postoperative months.

RESUMO

BACKGROUND: Trametes robiniophila Murr (Huaier) has been used as an adjuvant therapy of tumor in traditional Chinese medicine for many years, but the underlying mechanisms are largely unknown. In the present study, we tested the inhibitory effect of Huaier extract on renal cancer 786-O cells and explored the possible mechanisms. METHODS: 786-O cells were treated by gradient concentrations of Huaier extract, cell viability, invasion, migration and apoptosis were assessed by cell counting kit 8, cell scratch, transwell, and flow cytometry assay in vitro. The changes in protein level were detected by western blot analysis. Finally, the anticancer effect of Huaier was tested in vivo by nude mouse tumorigenicity assay. RESULTS: Viability of 786-O cells was suppressed by Huaier in a time- and dose-dependent manner; cell invasion and migration were also dramatically inhibited. Flow cytometry assays showed that Huaier could induce cell apoptosis. Western blotting analysis indicated that Huaier suppressed the activation of PI3K/AKT/mTOR/p70S6K/4E-BP1 signaling pathway. We also found that Huaier could partly reverse the epithelialmesenchymal transition (EMT) process. In vivo experiment indicated that tumor growth in the xenograft mouse model was suppressed by Huaier. CONCLUSION: Huaier plays an anticancer effect partially through the suppression of the PI3K/AKT/mTOR/p70S6K/4E-BP1 pathway and by reversing the EMT process. Huaier may act as an effective agent for treating renal cell carcinoma.

RESUMO

This retrospective comparative study aims to explore the time courses of serum myoglobin (Mb) changes, and summarize our experience in treating patients with hypermyoglobinemia after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC).This study covered 60 patients with peritoneal carcinomatosis treated with CRS + HIPEC as the study group, and another 25 cancer patients treated with conventional extensive surgery without HIPEC as the control group from February to October 2016. In the study group, patients with postoperative hypermyoglobinemia were on a comprehensive treatment regimen consisting intravenous injection of sodium bicarbonate solution according to the Mb level. In the control group, patients were recorded and treated with the same regimen except for special sodium bicarbonate solution. The preoperative and postoperative serum Mb, blood urine nitrogen (BUN), and creatinine (Cr) levels were evaluated.There were no significantly difference between the 2 groups in serum Mb, BUN, and Cr levels before surgery. Postoperative serum Mb levels were elevated in both groups and significantly higher on postoperative 0 to 2 days (P < .05) in the study group than the control group. The peak value of serum Mb levels (426.65 ±â€Š108.386 µg/L) occurred on the surgery day. The serum Mb change rate was much bigger in the study group than the control group. Serum BUN levels in both groups revealed a slow increase during the early postoperative period and were significantly lower in the study group than the control group on days 1 and 2. The serum Cr levels were similar and stable between the 2 groups after surgery. The serum Cr change rates changed synchronously with same tendency in both groups, and on postoperative day 1 the increase rate was bigger in the control group than the study group.Hypermyoglobinemia is a common and prominent lab abnormality after CRS + HIPEC, and serum Mb levels could be an early and sensitive indicator for dramatic disturbances in the internal milieu after CRS + HIPEC. Adequate treatment with sodium bicarbonate could accelerate the reduction in serum Mb levels and reduce the risk for major organ damages.

RESUMO

We discuss the role of Salvianolic acid A(SAA), one of the main effective components in Salvia Miltiorrhiza (known as 'Danshen' in traditional Chinese medicine), in apoptotic factors, the production of oxidative products, and the expression of Akt and NF-κB in angiotensin II (Ang II)-mediated murine macrophages. In the present study, Ang II was added to mice abdominal macrophages with or without addition of SAA. After cell identification, apoptosis was measured by DNA strand break level with TdT-mediated dUTP nick-end labeling (TUNEL) staining, and the expression of Bcl-2 and Bax. Intracellular concentrations of superoxide dismutase (SOD) and malondialdehyde (MDA) were also measured. Western blotting determined the expression of Akt, p-Akt, NF-κB and p-NF-κB. Ly294002 (the inhibitor of PI3K) was used to determine the mechanism of SAA. Ang II (1 µM) significantly increased the number of TUNEL-positive cells and Bax expression, but reduced Bcl-2 expression. These effects were antagonized when the cells were pretreated with SAA. SAA decreased MDA, but increased SOD in the cell lysis solution treated with Ang II. It markedly reduced the level of p-NF-κB, as also p-Akt, which was partly blocked by Ly294002. SAA prevents Ang IIinduced apoptosis, oxidative stress and related protein expression in the macrophages. It also inhibits the activation of Akt.

RESUMO

The flavonoid luteolin exists in many types of fruits, vegetables, and medicinal herbs. Our previous studies have demonstrated that luteolin reduced ischemia/reperfusion (I/R) injury in vitro, which was related with sarcoplasmic reticulum Ca(2+)-ATPase (SERCA2a) activity. However, the effects of luteolin on SERCA2a activity during I/R in vivo remain unclear. To investigate whether luteolin exerts cardioprotective effects and to monitor changes in SERCA2a expression and activity levels in vivo during I/R, we created a myocardial I/R rat model by ligating the coronary artery. We demonstrated that luteolin could reduce the myocardial infarct size, lactate dehydrogenase release, and apoptosis during I/R injury in vivo. Furthermore, we found that luteolin inhibited the I/R-induced decrease in SERCA2a activity in vivo. However, neither I/R nor luteolin altered SERCA2a expression levels in myocardiocytes. Moreover, the PI3K/Akt signaling pathway played a vital role in this mechanism. In conclusion, the present study has confirmed for the first time that luteolin yields cardioprotective effects against I/R injury by inhibiting the I/R-induced decrease in SERCA2a activity partially via the PI3K/Akt signaling pathway in vivo, independent of SERCA2a protein level regulation. SERCA2a activity presents a novel biomarker to assess the progress of I/R injury in experimental research and clinical applications.

RESUMO

BACKGROUND: Chrysanthemi indici Flos, a traditional herbal medicine is used to clearing heat-toxicity, removing the liver fire, and improving eyesight. In our preliminary work, an active extract of CTC in C. An indici Flos with anti-hepatitis B virus and liver protective activity was found by HepG2.2.1.5 test and experiment of protein synthesis in mice's injured liver. In this work, we aimed to study the active faction CTC further by qualitative and quantitative analysis method. MATERIALS AND METHODS: High performance liquid chromatography time of flight electrospray ionization mass spectrometry (HPLC TOF ESI-MS) analysis method of the CTC was established. Cumambrin A and angeloylcumambrin B in CTC were analyzed by high performance liquid chromatography-ultraviolet-evaporative light scattering detector (HPLC-UV-ELSD) analysis methods. A binary gradient elution program was conducted for chromatographic separation with acetonitrile (A) and ultrapure water (B) as follows: 0-10 min, 42-46% A; 10-20 min, 46-55% A; 20-25 min, 55-60% A; and 25-35 min, 60-75% A. The column temperature and UV wavelength were set at 30°C and 205 nm. RESULT: Ten constituents including (3R, 5R, 6S, 7S, 10R)-7-(2-hydroxy-2-propyl)-10-methyl-4-methyleneperhy, dronaphthal-ene-3, 5, 6-triol acetone solvate; (+)-edusmance-4, (14)-ene-11, 13-diol; linarin; luteolin; apigenin; tricin; 5, 3',4'- trimethyl-6,7-dimethoxy flavones; cumambrin A; acacetin; and angeloylcumambrin B in CTC were identified by HPLC TOF ESI-MS. The contents of sesquiterpenes in CTC were decreased by storing years. CONCLUSIONS: The results showed that both UV and ELSD methods were feasible, accurate, and the determination results were in good consistency. The contents of two sesquiterpenes decreased with storing years. Two sesquiterpenes could be used as quality control for C. indici flos CTC.

RESUMO

Triple negative breast cancer (TNBC) presents clinical challenges due to unknown etiology, lack of treatment targets, and poor prognosis. We examined combined genetic and nutritional risk models of TNBC in 354 breast cancer cases. We evaluated 18 DNA-repair nonsynonymous single nucleotide polymorphisms (nsSNPs) and dietary/nutritional intakes. Multivariate Adaptive Regression Splines models were used to select nutrients of interest and define cut-off values for logistic regression models. Our results suggest that TNBC was associated with 6 DNA-repair nsSNPs, ERCC4 R415Q (rs1800067), MSH3 R940Q (rs184967), MSH6 G39E (rs1042821), POLD1 R119H (rs1726801), XRCC1 R194W (rs1799782), and XPC A499V (rs2228000) and/or deficiencies in 3 micronutrients (zinc, folate, and ß-carotene). Combined analyses of these 6 nsSNPs and 3 micronutrients showed significant association with TNBC: odds ratios = 2.77 (95% confidence interval = 1.01-7.64) and 10.89 (95% confidence interval = 3.50-33.89) for 2 and at least 3 risk factors, respectively. To the best of our knowledge, this is the first study to suggest that multiple genetic and nutritional factors are associated with TNBC, particularly in combination. Our findings, if validated in larger studies, will have important clinical implication that dietary modulations and/or micronutrient supplementations may prevent or reverse TNBC phenotype, so tumors can be treated with less toxic therapeutic strategies, particularly in genetically susceptible women.

RESUMO

A series of oxadiazole derivatives containing 1,4-benzodioxan (4a-4s) have been first synthesized for their potential immunosuppressive activity. Among the compounds, compound 4i showed the most potent biological activity against RAW264.7 cells (inhibition=37.66±2.34% for NO overproduction and IC(50)=0.05µM for iNOS). Docking simulation was performed to position compound 4i into the iNOS structure active site to determine the probable binding model. RT-PCR experiment results demonstrated that some of these compounds possessed good immunosuppressive activity against iNOS, especially for compound 4i. Therefore, compound 4i with potent inhibitory activity may be a potential agent.
