ABSTRACT

Objective:To evaluate the effects of the nadirs of neutrophils and lymphocytes during concurrent chemoradiotherapy (CCRT) on clinical prognosis of patients with cervical cancer, aiming to provide reference data for clinicians.Methods:Clinical data of FIGO (2018)Ⅰ B1-Ⅳ A cervical cancer patients treated with radical CCRT in the University of Hong Kong-Shenzhen Hospital, from January 2015 to September 2019 were analyzed. Routine blood test was performed weekly. The overall survival (OS) was calculated by Kaplan- Meier method and analyzed by log-rank test. Univariate and Multivariate prognostic analysis were performed by Cox proportional hazards model. Results:A total of 87 patients were included. The cutoff values of absolute neutrophil count nadir (ANC n) and absolute lymphocyte count nadir (ALC n) for predicting OS were determined by receiver operating characteristic curve. Compared with the ANC n of ≤2.14×10 9/L ( n=76), patients with the ANC n of > 2.14×10 9/L ( n=11) had lower 2-year OS rate (54.5% vs. 88.9%, P=0.035). Compared with ALC n of > 0.2×10 9/L ( n=49), patients with ALC n of ≤0.2×10 9/L ( n=38) obtained lower 2-year OS rate (75.3% vs. 90.8%, P=0.008). Multivariate analysis showed that ANC n (>2.14×10 9/L vs. ≤2.14×10 9/L)( HR=4.487, 95% CI: 1.404-14.344, P=0.011), ALC n (≤0.2×10 9/L vs. >0.2×10 9/L)( HR=5.814, 95% CI: 1.822-18.554, P=0.003), concurrent chemotherapy cycle (5-6 cycles vs. 0-4 cycles)( HR=0.204, 95% CI: 0.060-0.696, P=0.011) and the mean body radiation dose ( HR=1.296, 95% CI: 1.125-1.493, P<0.001) were significantly associated with OS. Patients with the ANC of > 5.19×10 9/L before CCRT were more likely to have ANC n of > 2.14×10 9/L during CCRT and those with the ALC of < 2.05×10 9/L before CCRT was more likely to have ALC n of ≤0.2×10 9/L during CCRT. Conclusions:Peripheral ANC n and ALC n during CCRT have different prognostic effects and influencing factors. Clinical prognosis of cervical cancer patients may be improved by closely monitoring routine blood parameters and optimizing treatment modality during CCRT.

ABSTRACT

Objective:To investigate the expression changes at the transcriptional level in normal lung tissues of mice after exposure to heavy ion radiation for different durations at different doses, aiming to provide evidence for exploring sensitive genes of heavy ion radiation, heavy ion radiation effect and the damage mechanism.Methods:Experiments on the temporal kinetics: the whole thorax of mice was irradiated with 14.5Gy carbon-ions and the total RNA of lung tissue was extracted at 3days, 7days, 3 weeks and 24 weeks. In dose-dependent experiment, the total RNA of lung tissue was extracted at 1 week after irradiated with a growing thoracic dose of 0, 7.5, 10.5, 12.5, 14.5, 17.5 and 20Gy. Protein-to-protein interaction (PPI) analysis and gene-ontology biological process enrichment analysis were performed on significant differentially expressed genes (DEGs).Results:A clearly differential expression patterns were observed at 3-day (acute stage), 1-week (subacute stage), 3-week (inflammatory stage) and 24-week (fibrosis stage) following 14.5Gy carbon-ions irradiation. Among those, the 3-day time point was found to be the mostly different from the other time points, whereas the 7-day time point had the highest uniformity with the other time points. Cellular apoptosis was the main type of cell death in normal lung tissues following carbon-ions exposure. The interactive genes of Phlda3, GDF15, Mgmt and Bax were identified as the radiosensitive genes, and Phlda3 was the center ( R=0.76, P<0.001). Conclusion:The findings in this study provide transcriptional insights into the biological mechanism underlying normal lung tissue toxicity induced by carbon-ions.

ABSTRACT

Objective@#To investigate the safety and feasibility of proximal partial gastrectomy with Cheng's Giraffe esophagogastric reconstruction for the treatment of early Siewert II adenocarcinoma of esophagogastric junction (AEG).@*Methods@#Indication of Cheng's Giraffe esophagogastric reconstruction: (1) Siewert II AEG or Siewert III AEG with diameter < 4 cm; (2) preoperative staging as cT1-2N0M0. A descriptive case series study was carried out. Clinical data of 34 patients with Siewert II AEG undergoing proximal partial gastrectomy and Cheng's Giraffe esophagogastric reconstruction at Department of Abdominal Surgery of Zhejiang Cancer Hospital and Department of Gastrointestinal Surgery, The First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine from February to July 2018 were retrospectively collected and analyzed, including 14 cases in IA stage, 11 cases in IIA stage and 8 cases in IIB stage. Brief procedure of Cheng's Giraffe esophagogastric reconstruction was as follows: Firstly, 12 cm long tubular stomach was formed by longitudinal incision 4 cm away from the great curvature of the stomach. Secondly, the gastric fundus and His angle were formed. Finally, the distance from His angle to esophagal-tubular gastric anastomosis should be more than 5 cm. The reflux disease questionare (RDQ) scores, radionuclide gastric emptying scintigraphy, and 24-hour multichannel intraluminal (MII)-pH monitoring technology were used to evaluate postoperative gastric emptying and gastroesophageal reflux.@*Result@#All 34 patients successfully completed proximal partial gastrectomy with Cheng's Giraffe esophagogastric reconstruction, including 13 cases by open surgery and 21 cases by laparoscopic surgery. The operation time was (144.6±39.8) minutes, the blood loss during operation was (35.4±17.2) ml. No laparoscopic case was converted to open surgery and no postoperative complication was observed. The postoperative hospital stay was (8.4±2.5) days. The postoperative RDQ score was 4.4±3.1 one month after operation, and 3.3±2.5 six months after operation. Gastric-half emptying time was (67.0±21.5) minutes, and the residual ratio was (52.2±7.7)% in 1 hour, (36.4±3.1)% in 2 hours and (28.8±3.6)% in 3 hours at postoperative 1-month. The 24-hour MII-pH monitoring at postoperative 2-month revealed the frequency of acid reflux was (12.6±7.9) times, frequency of non-acid reflux was (19.6±9.7) times, DeMeester score was 5.8±2.9.@*Conclusion@#Cheng's Giraffe esophagogastric reconstruction is safe and feasible in the treatment of Siewert type II AEG, and has good dynamic and anti-reflux effects.

ABSTRACT

Objective@#To investigate the effect of triptolide, a specific inhibitor of heat shock protein 70 (HSP70), on apatinib resistance in gastric cancer cells line MKN45.@*Methods@#The apatinib-resistant cells (MKN45/AR) and MKN45 parental cells were treated with apatinib, triptolide and apatinib combined with triptolide, respectively. CCK-8 assay was performed to determine the half maximal inhibitory concentration (IC50) of MKN45/AR and MKN45 cells in the presence of different treatment. The mRNA expression of heat shock protein gene (HSPA1A and HSPA1B) was detected by RT-PCR, while the protein expression of heat shock protein 70 was analyzed using Western blot in MKN45/AR and MKN45 cells.@*Results@#The IC50 values of apatinib-sensitive and apatinib-resistant MKN45 cells were 10.411 μmol/L and 70.527 μmol/L, respectively, showing a significant difference (P<0.05). The mRNA expression of HSPA1A and HSPA1B in MKN45/AR cells was significantly higher than that in MKN45 cells (P<0.001). The protein expression of heat shock protein 70 was significantly decreased after 0.25 μmol/L triptolide treatment in MKN45/AR cells (P<0.01). When heat shock protein 70 was inhibited by triptolide, the IC50 value of apatinib in MKN45/AR cells was reduced to 11.679 μmol/L, which was significantly lower than cells treated with apatinib alone (P<0.05).@*Conclusions@#The apatinib-resistant MKN45 cells have high levels of heat shock protein 70. Low doses of triptolide can significantly inhibit heat shock protein 70, leading to reverse the resistance phenotype of MKN45/AR cells. Therefore, inhibition of heat shock protein 70 provides a new therapy strategy for patients with apatinib resistance.

ABSTRACT

<p><b>OBJECTIVES</b>To study the correlation between MRI apparent diffusion coefficient (ADC) and expression of Ki-67 in gastric cancers, and to investigate the application of ADC value in diagnosing the malignance of gastric cancer.</p><p><b>METHODS</b>A retrospective cohort analysis was performed on 87 gastric cancer patients who received MRI examination and radical resection at Zhejiang Provincial Hospital of Traditional Chinese Medicine from November 2014 to August 2015. All the postoperative resected samples were confirmed as gastric cancer. Preoperative MRI examination was performed by using Siemens 3.0-T Verio MRI with following parameters: section thickness 3 mm, gap 1 mm, matrix 182×320, field of view 40 cm. Plain scan was followed by T1-weighted fat suppression technique VIBE 3D(TR3.92/TE1.39,90degree) scans at arterial phase (the 30th second), portal venous phase (the 60th second), lag period (the 90th second), axial planes and coronal planes (the 180th second), and sagittal planes (the 210th second), respectively. ADC value of tumor was measured at b-factor of 800 s/mmand ADC map was generated from DWI data on the work station. The expression of Ki-67 in cancer tissue was detected by routine immunohistochemical (SP) staining after surgery. Correlation between ADC value and the expression of Ki-67 in gastric cancer was analyzed.</p><p><b>RESULTS</b>Irregular thickening of the gastric wall and inhomogeneous enhancement of the tumor after injection of the contrast material appeared in gastric cancer. Gastric cancer tissue presented hyperintensity and normal gastric wall presented isointensity in DWI image (b=800 s/mm). Compared with normal gastric tissue, mean ADC value of gastric cancer tissue was significant lower [(1.114±0.265)×10mm/s vs. (2.032±0.202)×10mm/s, t=26.209, P=0.000]. The ADC values of high-middle differentiation group, middle-low differentiation group, low differentiation group and signet ring cell carcinoma/mucinous adenocarcinoma group were (1.347±0.234)×10mm/s, (1.179±0.257)×10mm/s, (0.996±0.185)×10mm/s and (1.082±0.230)×10mm/s, respectively. The difference of mean ADC value among different tumor stages was significant(F=8.498, P=0.000). Along with the Ki-67 expression up-regulated, the ADC value decreased in cancer tissue. The Ki-67 expressions in cancer tissue was negatively correlated with cancer ADC values (r=-0.570, P=0.000). Furthermore, negative correlations of Ki-67 expressions with ADC values of high-middle differentiation group (r=-0.627, P=0.016), low differentiation group (r=-0.787, P=0.000) and signet ring cell carcinoma/mucinous adenocarcinoma group (r=-0.792, P=0.000) were observed respectively, while Ki-67 expression was not correlated with ADC value of middle-low differentiation group.</p><p><b>CONCLUSION</b>The ADC value of gastric cancer can reflect the level of tumor differentiation, and is negatively correlated with Ki-67 expression in cancer tissues.</p>

ABSTRACT

Cholesterol is an essential nutrient for human body.Dietary cholesterol comes from animal sources,including eggs,pork and others.A number of epidemiological and experimental studies showed that too much intake of cholesterol or consumption of more than 1 egg per day would slightly elevate blood cholesterol level.Results of studies in different areas and populations suggested that there is a lack of sufficient evidence to support the association between cholesterol intakes or egg consumption and cardiovascular disease incidence or deaths.

ABSTRACT

Objective:To investigate if in vitro chemotherapy can induce the EMT progress in gastric cancer (GC) cells. Method:The GC cell line, SGC7901, was treated using 5-Fu at a concentration of 30 μg/mL. The residual cells after four cycles of 5-Fu therapy were named as SGC7901/Fu. The morphological changes and malignant biological features, including the invasiveness and clone formation ability and the characteristics of cancer stem cell and biomarkers of EMT between SGC7901 and SGC7901/Fu, were compared. Results:The SGC7901/Fu cells displayed a mesenchymal appearance, decreased the expression of epithelial markers, and increased the expression of mesenchymal markers. The 50% inhibitory concentrations in the SGC7901/Fu and SGC7901 cells were (43.8 ± 7.2) and (64.6 ± 5.5)μg/mL, respectively. The number of cells that migrated through the basement-membrane of the Transwell chamber was 51.4 ± 8.7 and 93.2 ± 9.5, respectively. The rate of clone formation was 5.2%± 1.0%and 13.2%± 2.2%, respectively. The portions of the CD44+/CD24-cells were 4.13%±0.81%and 7.97%±0.50%, respectively. All differences were statistically significant (P<0.05). Conclusion:The residual GC cells underwent EMT progress after 5-Fu treatment, with increased chemoresistance and ability of invasiveness and acquired the property of cancer stem cells.

ABSTRACT

Objective To introduce the application of double liver hanging maneuver in anatomical right hemihepatectomy and share our own experience. Methods Twenty-four patients underwent right hemihepatectomy using double liver hanging maneuver, and the data were collected prospectively after operation. Another 49 patients underwent right hemihepatectomy using the traditional methods,serving as the control group. Results Retrohepatic tunnel was constructed in 27 patients, double liver hanging maneuver was successfully performed in 24 anatomical right hemihepatomy and failed in 3 patients due to the near proximity between the tumor and the middle line. Compared with the control group, blood loss was much less (t=3. 191 ,P<0.05), ALT and liver function recovered more quickly postoperatively and the difference in operative duration between the 2 groups was not significant (t=-1. 695,P>0. 05). There was about 1-2 cm wide space located between retrohepatic IVC and dorsal liver when the 2 tapes were tracted, and no injury in hepatic short veins and retrohepatic IVC occurred during the operation. Conclusion The double liver hanging maneuver can make anatomical right hemihepatectomy more accessible and safe.

ABSTRACT

Objective To analyze the clinical characteristics of autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and AIH/PSC or/PBC overlap syndrome in order to further understand the autoimmune liver diseases (AILD). Methods One hundred and nine patients with AILDs confirmed pathologically were collected between Jan. 2004 and June 2006. Of 109 patients, AIH was found in 27 eases, PBC in 67 cases, PSC in 4 eases, AIH-PSC overlap syndrome in 1 case and AIH-PBC overlap syndrome in 10 cases. The clinical and laboratory data of all patients were assessed retrospectively. Results The AILD was predominantly found in middle-aged women (73.3% ,80/109), and the main clinical manifestations were jaundice, malaise, anorexia and pruritus. The age distribution of patients with AIH showed a single peak at 50 years. Elevated serum gamma globulin and IgG were found in patients with AIH, of whom 62.9% (17/27) were positive for anti-nuclear antibody (ANA) and 3 were positive for liver-kidney microsomes type 1 antibody. The main histological changes in severe AIH cases included interface hepatitis (77.7 %) and bridging necrosis. Most of the PBC patients were presented with elevated serum alkaline phosphatase, glutamyl transpeptidase and IgM. Fifty patients (74.6%) were positive for anti-mitochondrial antibody (AMA) and AMA-M2. The pathological examination showed that 28. 3% of the cases were in Ⅰ or Ⅱ stage and 71.7% in Ⅲ or Ⅳ stage in patients with PBC who received liver biopsy. The pathologic change of reduction or even disappearing of bile ducts was found in 62. 6% patients with PBC. The clinical and pathological manifestations in patients with AIH-PBC overlap syndrome had both characteristics of PBC and AIH. Three out of 10 patients with AIH-PBC overlap syndrome were positive for ANA and AMA/AMA-M2. Conclusion Since AILD is not rare in Chinese, its diagnosis should be based on the clinical presentation, biochemical, immunological and histologic changes.
