ABSTRACT

Background/Aims@#Metabolic risk factors could accelerate hepatitis B virus (HBV)-related mortality; however, their impacts on disease severity in HBV-related acute on chronic liver failure (HBV-ACLF) patients remain unexplored. In this study, we assessed the effects of metabolic risk factors on the outcome of HBV-ACLF patients. @*Methods@#This study retrospectively enrolled antiviral therapy naïve HBV-ACLF patients from a single center in China. Patients were evaluated according to Child-Turcotte-Pugh score, Model for End-Stage Liver Disease (MELD) score, 30-day, 90-day mortality and survival rate to estimate the prognosis of HBV-ACLF. The impacts of different metabolic risk factors were further analyzed. @*Results@#A total of 233 patients, including 158 (67.8%) with metabolic risk factors and 75 (32.2%) without metabolic risk factors, were finally analyzed. Patients with metabolic risk factors had significantly higher MELD score (22.6±6.1 vs 19.8±3.8, p<0.001), 90-day mortality rate (56.3% vs 38.7%, p=0.017), and shorter median survival time (58 days vs 75 days: hazard ratio, 1.553; 95% confidence interval, 1.061 to 2.274; p=0.036) than patients without them. Moreover, metabolic risk factors were independently associated with patients’ 90-day mortality (hazard ratio, 1.621; 95% confidence interval, 1.016 to 2.585; p=0.043). Prediabetes/diabetes and hypertension were related to higher rates of infection and worse renal function in HBV-ACLF patients. @*Conclusions@#HBV-ACLF patients with metabolic risk factors, especially prediabetes/diabetes or hypertension, could have more severe disease and lower survival rates. In addition, the existence of metabolic disorder is an independent risk factor for HBV-ACLF patients’ 90-day mortality.

ABSTRACT

@#Objective    To compare the short-term and long-term effects of minimally invasive esophagectomy (MIE) and traditional open esophagectomy (OE) in patients with stage T1b esophageal squamous cell carcinoma (ESCC). Methods    We retrospectively analyzed the clinical pathology data of 162 patients undergoing thoracic surgery at Northern Jiangsu People's Hospital from 2015 to 2018 whose pathological diagnosis was stage pT1b ESCC. According to the surgical approach, they were divided into MIE group and OE group. There were 55 males and 21 females in the OE group, with an average age of 63.3±5.6 years, and 60 males and 26 females in the MIE group, with an average age of 64.7±6.1 years. The preoperative, intraoperative and postoperative data of the two groups were compared and followed up. Survival data were compared using Kaplan-Meier and log-rank tests between the two groups, and Cox proportional hazard regression models were used to analyze prognostic factors. Results    Compared with the OE group, the intraoperative bleeding volume of the MIE group was less (119.8±70.0 mL vs. 210.5±136.2 mL, P<0.001), and the lymph nodes dissected during the operation were more (19.1±7.4 vs. 13.8±5.9, P<0.001), the rate of postoperative pulmonary infections was lower (9.3% vs. 21.1%, P=0.036), but the operation time was longer (240.0±52.4 min vs. 179.5±35.7 min, P<0.001). Twenty-one patients had lymph node metastasis, and the lymph node metastasis rate was 13.0%. At the end of the follow-up, 19 patients died, and the overall survival (OS) at 1 year, 3 years, and 5 years after operation were 97.5%, 88.8% and 82.9%, respectively; 31 patients had recurrence and metastasis, and the disease-free survival (DFS) rate at 1 year, 3 years, and 5 years after operation was 95.1%, 80.9% and 75.6%. There was no significant difference in OS and DFS between the two groups. Multivariate Cox regression analysis of OS found that lymph node metastasis, anastomotic fistula and chylothorax were independent risk factors for OS. Multivariate Cox regression analysis of DFS found that lymph node metastasis, anastomotic fistula, chylothorax, and vascular cancer thrombus were independent risk factors for OS. Conclusion    MIE can achieve the same long-term effects as OE, with less intraoperative bleeding, more lymph nodes dissected, and lower incidence of postoperative pulmonary infections, but it takes longer operation time.

ABSTRACT

Objective:To investigate the 2 years’ efficacy of intravesical instillation of domestic BCG versus epirubicin in the prevention of recurrence of intermediate-risk or high-risk non-muscular invasive bladder cancer and predictive factors of BCG instillation.Methods:From July 2015 to June 2020, 18-75 years old patients with moderate to high-risk non muscle invasive bladder cancer (NMIBC) confirmed by pathological examination were involved. The ECOG score was 0-2. Exclusion criteria included ①immune deficiency or impairment (such as AIDS), using immunosuppressive drugs or radiotherapy, suspected allergic to BCG or epirubicin or excipients of the two drugs, fever or acute infectious diseases including active tuberculosis or receiving anti tuberculosis treatment, with severe chronic cardiovascular and cerebrovascular diseases or chronic kidney disease; ②combined with other urogenital system tumors or other organ tumors; ③combined with muscle invasive bladder urothelial carcinoma (≥T 2); ④undergoing chemotherapy, radiotherapy or immunotherapy within 4 weeks (immediate instillation after surgery not included); ⑤ pregnant or lactating women; ⑥ comfirmed or suspected bladder perforation; ⑦gross hematuria; ⑧cystitis with severe bladder irritation that may affect the evaluation; ⑨participat in other clinical trials within 3 months; ⑩alcohol or drug addiction; ?any risk factors that may increasing the risk of patients. Epirubicin 50 mg was irrigated immediately after the operation(TURBT or laser resection). The patients were randomly divided into BCG15 group, BCG19 group and epirubicin group by the ratio of 2∶2∶1, and the patients were maintained intravescical instillation for 1 year. The recurrence and adverse events of the three groups were compared. Univariate and multivariate analysis was performed to predict the risk factors of BCG irrigated therapy failure. Result:By June 15, 2020, the median follow-up duration was 22.1 months(12.1, 32.3), and there was no statistical difference between the groups ( P=0.9024). There were 274 patients enrolled in BCG19 group, 277 patients enrolled in BCG15 group and 130 patients enrolled in the epirubicin group. The drop-off rate was 16.6%(113 cases)and made no difference between groups( P=0.6222). There were no significant difference in age, gender, BMI, or ECOG score( P>0.05). During the follow-up, 116 cases was detected recurrence or progression. The recurrence rate of the three groups was 14.2% and 14.8% in BCG19 group and BCG15 group, and 27.7% in the epirubicin group. There was no difference in recurrence rate between BCG19 and BCG15 group( P=0.9464). The recurrence rate of BCG19 group was lower than that of the epirubicin group ( P=0.0017). The recurrence rate of BCG15 group was lower than that of the epirubicin group ( P=0.0020). There was no difference in the cumulative recurrence free survival rate between BCG19 and BCG15 group (95% CI0.57-1.46, P=0.7173). The cumulative recurrence free survival rate of BCG 19 group was better than that of the epirubicin group( HR=0.439, 95% CI0.26-0.74, P=0.0006), and the cumulative recurrence free survival rate of BCG15 group was better than that of the epirubicin group ( HR=0.448, 95% CI0.29-0.80, P=0.0021). The total incidence of adverse events in 19 BCG19, BCG15 and epirubicin group were 74.5%, 72.6% and 69.8% respectively. There was no difference in the incidence of adverse events between BCG19 and BCG15 group( P=0.6153). The incidence of adverse events in epirubicin group was lower than that of BCG19( P=0.0051) and BCG15( P=0.0167) groups.There was no significant difference in the incidence of serious adverse events (SAE) among the three groups ( P=0.5064). Log rank test univariate analysis and Cox risk regression model multivariate analysis showed that the history of bladder cancer recurrence( HR=6.397, 95% CI1.95-20.94, P=0.0001)was independent risk factor for BCG irrigation failure. Conclusions:The 2 years’ efficacy of intravesical instillation of domestic BCG is better than than of epirubicin with good tolerance and safety. There is no difference between BCG19 and BCG15 group. BCG doesn’t increase SAE compared with epirubicin. Recurrence status was an independent prognostic factor regarding recurrence-free survival.

ABSTRACT

@# The concept of enhanced recovery after surgery (ERAS) was firstly demonstrated in practice by the Danish scholar Henrik Kehlet in the early 2000s. At present, the ERAS concept has been widely used in a variety of surgical fields, but its application in esophageal cancer surgery is still limited. The new esophageal ERAS guidelines issued by ERAS Association bring new opportunities for the application and promotion of esophageal cancer surgery. Combined with the current situation of esophageal cancer surgery in China and related literature, in this paper we discuss the specific measures of ERAS concept in perioperative application of esophageal cancer in China.

ABSTRACT

@#Objective    To investigate the clinical value of 3D CT combined with CT-guided Hookwire for localizing small pulmonary nodules in thoracoscopic pulmonary segmentectomy. Methods    From December 2017 to February 2019, 39 patients received thoracoscopic pulmonary segmentectomy in our hospital, including 14 males and 25 females with a mean age of 51.33±11.17 years. Before operation, we used Mimics Medical 20.0 to re-establish the anatomy of lung and locate the small pulmonary nodules with Hookwire guided by CT. Based on the position of Hookwire needle, 3D CT images and simulated surgical methods, thoracoscopic pulmonary segmentectomy was performed accurately. Results    The surgery was successfully completed in 39 patients without a transfer to open procedure. The mean operation time, mean intraoperative blood loss, mean postoperative hospital stay, mean thoracic tube drainage time were 148.97±28.56 min, 27.95±17.57 mL, 6.95±1.68 d, 4.21±1.95 d, respectively. Postoperative complications occurred in 5 patients (12.82%), including atrial fibrillation in 1, pulmonary infection in 1, chylothorax in 1, intrathoracic hemorrhage in 1 and pneumothorax in 1. All actual surgical margins were larger than 3.0 cm. Conclusion    The application of preoperative 3D CT combined with CT-guided Hookwire to localize small pulmonary nodules is helpful for accurate anatomical segmental resection of the lung, making the operation safe .

ABSTRACT

OBJECTIVE:To study the effects and mechanism o f apigenin on cisplatin sensitivity of NSCLC A 549 cells by regulating RAD51 gene. METHODS :Human lung cancer cisplatin-resistant cells A 549/DDP were selected and divided into control group(blank culture medium ),cisplatin group (5 g/L),apigenin low-dose and high-dose groups (10,20 μmol/L). MTT assay was used to detect the growth of A 549/DDP cells ,while the Annexin Ⅴ/PI double staining combined with flow cytometry were used to detect the apoptosis. A 549/DDP cells were collected and divided into cisplatin alone group (1,2,4,8,16 μg/mL), apigenin combination group (10 μmol/L,based on cisplatin ). MTT method was used to determine and calculate inhibitory rate of cell proliferation. IC 50 values of drugs were calculated by regression model ,and reversion index of apigenin was calculated. 18 nude mice were randomly divided into control group ,cisplatin alone group and apigenin combination group ,with 6 mice in each group. After A 549/DDP cells were inoculated to form the transplanted tumor ,normal saline ,cisplatin(2 mg/kg,once every other day ), cisplatin(the same dosage and usage )+apigenin solution (30 mg/kg,once a day )were injected intraperitoneally respectively. After 18 days of continuous administration ,the body weight of mice and the mass of the transplanted tumor were detected and the tumor inhibition rate was calculated. Human lung cancer cells A 549 and A 549/DDP were collected and divided into normal group (A549 cells),control group (A549/DDP cells ),cisplatin group (5 g/L,A549/DDP cells )and apigenin low-dose and high-dose groups (10,20 μmol/L,A549/DDP cells ),respectively. mRNA and protein expression of RAD51 were detected by real-time fluorescence quantitative PCR and Western blotting assay.

After combined with apigenin ,proliferation inhibition rate of A 549/DDP cells was increased significantly ,compared with cisplatin alone group with the same concentration (P<0.05). The IC 50 in the apigenin combination group was (5.81±0.47)μg/mL,significantly lower than (14.44±0.52)μg/mL in cisplatin alone group(P<0.05),and reversal index of apigenin was 2.49. The results of nude mice tumor inhibition experiment showed that after combined with apigenin,tumor inhibition rate of A 549/DDP bearing nude mice was 68.72%,significantly lower than 33.82% in cisplatin alone group. Compared with A 549 cells of normal group ,relative expression of RAD51 mRNA and protein were increased significantly in A549/DDP cells of control group (P<0.05). Compared with A 549/DDP cells of control group ,relative expression of RAD51 mRNA and protein in A 549/DDP cells were decreased significantly in apigenin low-dose and high-dose groups (P<0.05). Compared with cisplatin group ,relative expression of RAD51 mRNA and protein in A 549/DDP cells of apigenin low-dose and high-dose group were decreased significantly (P<0.05). CONCLUSIONS :Apigenin can effectively reverse drug resistance of cisplatin-resistant A 549/DDP cells in human lung cancer. The mechanism may be related to the reduction of RAD51 gene transcription and protein expression.

ABSTRACT

Objective To investigate the efficacy and safety of intravesical instillation of BCG vaccine in the prevention of early recurrence of middle and high risk non-muscle invasive bladder cancer.Methods From July 2015,patients with non-muscle invasive bladder cancer aged 18-75 years with informed consent were screened and underwent transurethral resection of bladder tumor (TURBT).Immediately intravesical instillation of epirubicin 50 mg was given postoperatively.After pathology was comfirmed,patients was enrolled in group 1 (BCG15) or group 2 (BCG 19) or the control group (epirubicin 18) randomly with SAS 9.3 software.Data of follow-up and Adverse event was collected and analyzed.Results By May 31,2019,531 patients were enrolled in the study.The drop-off rate was 20.1%.167 patients (143 males and 24 females)in group 1,172 patients (141 males and 31 females)in group2 and 84(75 males and 9 females) in the control group with follow-up data were analyzed.There were no significant differences in age,gender,BMI,ECOG score,risk stratification between the three groups (P =0.8641,P =0.2906,P =0.9384,P =0.6126).The median follow-up time makes no statistical difference between the groups (P =0.9251),12.0 (6.0,22.5) months,13.0 (6.0,22.3) months,and 13.0 (7.0,22.3) months.The median recurrence time of the three groups was 4.0 (3.0,6.0) months,4.5 (3.0,9.8) months,4.5 (3.0,8.8) months.There was no statistical difference between the three groups (P =0.2852).Risk stratification in the patients got no significant difference between the three groups (P > 0.05).The 1-year recurrence-free survival rates were 80.0% in the group 1 and 88.3% in the group 2 and 73.7% in the control group.The group 2 was superior to the group 1 and the control group (P =0.0281,P =0.0031).There was no significant difference between group 1 and control group (P =0.2951).There was no significant difference in the cumulative recurrence-free survival between the experimental group 1 and the experimental group 2,(95% CI 0.80-2.43,P =0.2433).The cumulative recurrence-free survival in the group 1 and the group 2 was better than the control group (95 % CI 0.31-0.92,P =0.0266;95 % CI 0.20-0.65,P =0.0008).All the cases underwent instillation were analyzed for adverse events.The incidence of overall AE(adverse events) in group 1 was 68.5% (152/222),the incidence of grade Ⅰ-Ⅱ AE was 53.2% (118/222),the incidence of grade Ⅲ-Ⅳ AE was 15.3% (32/222).The incidence of overall AE in the group 2 was 71.8% (160/223),the incidence of grade Ⅰ-Ⅱ AE was 60.1% (134/223),and the incidence of grade Ⅲ-Ⅳ AE was 11.7% (26/223).The overall AE rate in the control group was 53.2% (59/111),of which the incidence of grade Ⅰ-Ⅱ AE was 42.4% (47/111),and the incidence of grade Ⅲ-Ⅳ AE was 10.8% (12/111).There was no difference in the incidence of overall AE between the group 1 and the group 2 (P =0.4497).The incidence of AE in the two experimental groups was higher than that in the control group (P =0.0062,P =0.0008).There was no difference in the incidence of grade Ⅲ-Ⅳ AE between the three groups (P =0.3902).Conclusions BCG(19 instillation schedule) has a better effect on preventing recurrence after 1 year of bladder surgery,which is superior to epirubicin group.The long-term efficacy of BCG in preventing recurrence and the efficacy of different schedules need to be further followed up.The lower urinary tract symptoms,which are mainly urinary frequency,are one of the causes of case fallout and should be fouced in future.Compared with epirubicin,BCG perfusion does not increase the incidence of grade Ⅲ-Ⅳ adverse reactions,and is safe to use.

ABSTRACT

BACKGROUND@#The pathogenesis of a ciliated muconodular papillary tumor (CMPT) of the lung is extremely rare which is difficult to distinguish from other lung lesions and it is easy to cause misdiagnosis and missed diagnosis. By collecting CMPT data, its clinical and pathological features can provide medical treatment ideas for the majority of medical workers and reduce medical errors.@*METHODS@#The clinical data, pathological features, immunophenotype of a typical CMPT patient and related literature were analyzed.@*RESULTS@#The chest computed tomography (CT) showed there was a mixed density nodule in the right lower lung near the pleura with a diameter of about 9 mm. We performed a wedge resection on the patient. The pathological results showed that the nodule was composed of proliferated ciliated cells, mucous cells, and basal-like cells. The ciliated cells were lined on the surface of papillary structures. The basal-like cells were located in the outer layer, while the mucous cells were located between the two. The cell atypia was not obvious. Immunohistochemistry: epithelial cells CEA (+), CK7 (+), CA125 (+), weakly positive for TTF-1, CK20 (-), Ki67 (1%+), CK5/6 (+), and basal cells P63 (+).@*CONCLUSIONS@#CMPT is a rare pulmonary neoplasm. There is no definite conclusion about its biologic nature, but most experts prefer a benign to a malignant tumor. CMPT can show many malignant tumor signs on imaging and is often mistaken for lung adenocarcinoma. According to its typical histopathological characteristics and immunohistochemical phenotype, it can be differentiated from other pulmonary diseases. Whether gene mutation is the driving factor is still unknown. Surgical resection for the tumor reveals a good prognosis.

ABSTRACT

Objective To investigate the expression of Parkin protein in colorectal cancer and its clinical significance. Methods Immunohistochemistry was used to detect the expression of Parkin protein in normal and cancerous tissues of 50 patients with colorectal cancer from 2012 to 2015. The relationship between clinicopathological characteristics and Parkin protein expression was analyzed. Results The positive expression rate of Parkin protein in cancerous tissues was significantly lower than that in normal tissues: 36% (18/50) vs. 72% (36/50), and there was statistical difference (P<0.01). The positive expression of Parkin protein was correlated with the degree of tissue differentiation (P < 0.01);but it was not correlated with sex, age, tumor diameter, tumor type, tumor infiltration, lymph node metastasis and clinical stage (P>0.05). Conclusions In colorectal cancer tissues, the expression of Parkin gene is absent and decreased. The abnormal expression of Parkin gene may be related to the occurrence and development of colorectal cancer.

ABSTRACT

Objective@#To evaluate left ventricular (LV) dysfunction in patients with esophageal cancer (EC) during concurrent chemoradiotherapy (CCRT) using real-time three-dimensional speckle tracking echocardiography (3D-STE) and analyze its influence factors.@*Methods@#Thirty-one patients with EC who received CCRT were enrolled in the study.Conventional echocardiography and 3D-STE were performed pre-CCRT and during CCRT (radiotherapy dose reached 40Gy). Three-dimensional parameters including LV end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), left ventricular ejection fraction (LVEF), global longitudinal strain (GLS) as well as global circumferential strain (GCS) were compared between pre-CCRT and during CCRT. The independent factors on left ventricular function parameters were analyzed.@*Results@#There was no change on LV diameters, LV volumes and LVEF during CCRT (all P>0.05), while LV diastolic function indexes were impaired compared with those of pre-CCRT, demonstrated by the decreased E/A, Em/Am, and increased E/Em(all P<0.05). 3DGLS was also significantly decreased during CCRT compared with that of pre-CCRT (P<0.05), but no significant difference was found in 3DGCS (P>0.05). Multivariate linear regression analysis manifested that cardiac V40(the percentage of cardiac volume as radiotherapy dose reached 40Gy) was an independent determinant of LV 3DGLS in patients with esophageal cancer during CCRT (P<0.05).@*Conclusions@#LV GLS provided by real-time 3D-STE could sensitively detect CCRT-induced myocardial injury. Cardiac V40 is independently associated with LV 3DGLS during CCRT, representing the impact of radiotherapy on the subclinical LV function change.

ABSTRACT

PURPOSE: The transforming growth factor β1 (TGF-β1)/SMAD family member 3 (SMAD3) pathway, and hypoxia-inducible factor 1α (HIF-1α) are two key players in various types of malignancies including breast cancer. The TGF-β1/SMAD3 pathway can interact with HIF-1α in some diseases; however, their interaction in breast cancer is still unknown. Therefore, our study aimed to investigate the interactions between the TGF-β1/SMAD3 pathway and HIF-1α in breast cancer. METHODS: Expression of HIF-1α in serum of breast cancer patients and healthy controls was detected by quantitative reverse transcription polymerase chain reaction, and the diagnostic value of HIF-1α for breast cancer was evaluated by receiver operating characteristic curve analysis. Breast cancer cell lines overexpressing SMAD3 and HIF-1α were established. Cell apoptosis and proliferation following different treatments were detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, and cell counting kit-8, respectively. Expression of related proteins was detected by western blot. RESULTS: Serum levels of HIF-1α were higher in breast cancer patients than in normal controls. Both SMAD3 and HIF-1α overexpression inhibited cell apoptosis and promoted cell proliferation. Treatment with inhibitors of HIF-1α and SMAD3 promoted apoptosis in breast cancer cells and inhibited their proliferation. Overexpression of HIF-1α promoted the expression of TGF-β1 and SMAD3, while SMAD3 overexpression did not significantly affect expression of HIF-1α or TGF-β1. CONCLUSION: HIF-1α serves as an upstream regulator of the TGF-β1/SMAD3 pathway and promotes the growth of breast cancer.

ABSTRACT

Objective To observe the clinical efficacy of umbilical compress with anti-cancer Xiaogu formula in managing malignant ascites. Methods A total of 56 patients with malignant ascites who met the inclusion criteria were randomized into 28 patients in the treatment group and 28 patients in the control group. The control group was treated with one type of diuretic, and the treatment group was given umbilical compress using Anti-Cancer Xiaogu formula and diuretics. Both groups were treated for 14 days. The changes of abdominal girth, 24 h urine volume, ascites efficacy, TCM syndrome scores, quality of life and adverse reactions were observed. Results The decrease in the maximum depth difference of the ascites in the treatment group was significantly greater than that of the control group (1.16 ± 1.29 vs. 0.00 ± 1.34, Z=-2.553). The difference was statistically significant (P<0.05). The decrease in abdominal girth in the treatment group was significantly larger than that in the control group (0.57 ± 0.55 vs. 2.61 ± 0.28, Z=-2.264). The difference was statistically significant (P<0.05). The in 24-hour urine volume in the treatment group after intervention (-800.18 ± 64.12 vs.-683.57 ± 55.38, Z=-1.770) was no statistically significant (P>0.05). The response rate in the treatment group was 92.9% (26/28), while that of the control group was 89.3% (25/28).treatment group was 71.4%, while that of the control group was 35.7%. The difference was statistically significant (P<0.05). The increase in KPS in the treatment group was significantly higher than that of the control group. The difference was statistically significant (P<0.05). Conclusions Anti-cancer Xiaogu umbilical cord combined with diuretic can reduce the degree of malignant ascites, alleviate clinical symptoms, improve quality of life and decrease the occurrence of adverse reactions when used concomitantly with diuretics in the management of malignant ascites.
