ABSTRACT

Objective To compare the clinical efficacy between traditional laparoscopic surgery and laparoscopic surgery under the guidance of membrane anatomy with complete mesangectomy in the treatment of rectal cancer. Methods A retrospective cohort study was conducted on 60 patients with rectal cancer who were randomly divided into control group (n=30) and observation group (n=30) in accordance with the principle of randomization.The control group received traditional laparoscopic radical resection of rectal cancer, and the observation group received laparoscopic radical resection of rectal cancer under the guidance of membrane anatomy with complete mesangectomy.The different clinical application effects of the two groups were analyzed by comparing the general data, operation time, intraoperative blood loss, and postoperative rehabilitation. Results All the 60 patients underwent the laparoscopic radical resection of rectal cancer.No operation-related complications, conversion to laparotomy, or perioperative death cases were reported.No statistically significant differences in age, gender, operation time, postoperative exhaust time, drainage tube removal time, or postoperative complications were found between the two groups (all P > 0.05).Compared with the control group, the observation group had significantly less intraoperative blood loss and more lymph node dissected (P < 0.05). Conclusion Laparoscopic radical resection of rectal cancer guided by the membrane anatomy with complete mesangectomy can completely remove the mesorectum, enlarge and clear the surgical field, reduce intraoperative bleeding, thoroughly remove lymph nodes, and improve the quality of surgery.

ABSTRACT

Objective To observe the effects of amarogentinon liver cancer stem cells (LCSCs) after insufficient thermal ablation and its mechanism. Methods A insufficient thermal ablation model of HepG2 cells was established by water bath method.The percentage of CD133-positive LCSCs and the mRNA and protein levels of CD133 were detected by flow cytometry, qRT-PCR and Western blot.The insufficient thermal ablation model of HepG2 cells was treated with variable doses of amarogentin for 24 h; the percentage of CD133-positive LCSCs, the proliferation and apoptosis of liver cancer cells, and the mRNA and protein levels of CD133, TBC1D15, and p53were detected by flow cytometry, qRT-PCR and Western blot. Results The percentage of CD133-positive HepG2 cells and the mRNA and protein levels of CD133 and TBC1D15in the insufficient thermal ablation model were significantly higher than those in the normal HepG2 cells.Amarogentin then markedly decreased the percentage of CD133-positive LCSCs, the proliferation rate of HepG2 cells, and the mRNA and protein levels of CD133 and TBC1D15 in the insufficient thermal ablationresidual model (all P < 0.05);inversely, the apoptosis rate of HepG2 cells and the phosphorylated levels of p53 in the insufficient thermal ablation model were significantly increased (all P < 0.05). Conclusion Amarogentin could reduce the proportion of LCSCs after insufficient thermal ablation, inhibit the proliferation, and promote the apoptosis of LCSCs, which maybe associated with increasing the phosphorylation of p53 and inhibiting the expression of TBC1D15.

ABSTRACT

Objective@#To explore the association between maternal pre pregnancy and pre delivery overweight with overweight and obesity among offspring during adolescence in Guangzhou, and to provide evidence for child obesity prevention.@*Methods@#Based on the routine physical examination of primary and secondary school students in Guangzhou, random sampling was used to 6 middle schools and questionnaire survey was conducted among 3 384 students and their parents. Students with overweight and obesity were included in the case group, and the other students were included in the control group. Propensity Score Matching (PSM) was adopted to reduce selection bias. Logistic regression model and χ 2 test were used to analyze the data before and after PSM.@*Results@#The result of univariate analysis showed that there were statistically significant differences between overweight/obese group and the control group by gender, schooling stage (middle and high schools), picky eater, family history of obesity, family monthly income, delivery mode, high birthweight, and gestational weight gain before PSM( χ 2=42.38, 10.64, 14.47, 26.85, 10.58, 13.59 , 15.53, 20.64, P <0.05). After PSM, results showed that there were no statistically significant differences between overweight/obese group and the control group in middle and high schools, and mother delivery mode( P >0.05). Logistic regression analysis showed that the risk of overweight and obesity of maternal pre pregnancy on adolescent offspring was 1.54 times higher than control group (95% CI =1.01-2.36) before PSM, and the overweight and obesity of maternal predelivery also increased the risk of overweight and obesity of adolescent offspring( OR=2.35, 95%CI =1.67-3.31). After PSM, maternal overweight and obesity pre pregnancy ( OR=2.17, 95%CI =1.41-3.34) and maternal overweight and obesity pre delivery( OR=2.99, 95%CI =2.08-4.31) significantly increased the risk of overweight and obesity in adolescent offspring.@*Conclusion@#Maternal overweight and obesity pre pregnancy and pre delivery are associated with increased risk of overweight and obesity in adolescent offspring.

ABSTRACT

Pancreatic cancer is one of the most malignant digestive cancer with high morbidity and mortality. Surgical treatment is considered the only way to cure pancreatic cancer. For resectable pancreatic cancer, the principles of "artery-frst approach" and "systematic mesopancreas dissection" have improved the increase the local radicality and reduce the local recurrence rate. For borderline resectable pancreatic cancer and locally advanced pancreatic cancer, neoadjuvant chemotherapy can be used before surgical resection. Although there are no targeted and immunotherapeutic drugs for pancreatic cancer, clinical studies on monoclonal antibodies are ongoing. Chimeric antigen receptor T cell therapy and irreversible electroporation are emerging therapies in the treatment of pancreatic cancer. In the present study, the status and progress of comprehensive treatment for pancreatic cancer are reviewed.

ABSTRACT

Pancreatic duct stones are closely related to chronic pancreatitis. Although the incidence is low, they can cause intractable abdominal pain and may lead to pancreatic cancer. Changes in the composition of pancreatic juice are the essential causes for the formation of pancreatic duct stones, while local inflammation and pancreatic ductal stenosis are the direct causes of the progression of stones and the recurrence of the symptoms, and they are also the main targets of treatment. Endoscopic treatment combined with extracorporeal shock-wave lithotripsy has a good therapeutic effect on most pancreatic duct stones. More complex stones require surgical intervention. The choice of specific surgical methods is related to the size and distribution of the stones. Treatment schemes should aim at reducing long-term stones or pain recurrence, and preserving more endocrine and exocrine functions of the pancreas, in order to bring greater benefits to patients.

ABSTRACT

Pancreatic cancer is highly malignant, and surgical resection is the only cure method at present. In recent years, neoadjuvant therapy has enabled some patients to be successfully downgraded with surgical treatment, which increased the R0 surgical resection rate and prolonged the survival time of patients, has become an important part in the treatment of pancreatic cancer. However, the applicability and standardization of neoadjuvant therapy for pancreatic cancer still need more advanced evidence. This article reviews whether neoadjuvant therapy should be used for resectable pancreatic cancer, the choice of neoadjuvant chemotherapy, and the progress, advantages and disadvantages of neoadjuvant chemoradiotherapy.

ABSTRACT

Purpose@#Pancreatic duct decompression relieves pancreatic duct stone (PDS)-associated abdominal pain, though a consensus indication for the drainage procedure of the main pancreatic duct (MPD) is lacking. Moreover, major prognostic factors for postsurgical long-term pain relief and recurrence are largely unknown. @*Methods@#The clinical outcomes of 65 consecutive PDS patients undergoing surgery from 2008–2012 with 3+ years of follow-up were assessed. @*Results@#At postsurgical follow-up (median, 4.5 years; range, 3–7 years; procedure: Partington, n = 32; Frey, n = 27; pancreatoduodenectomy, n = 3; distal pancreatectomy, n = 3), the early complication and complete stone clearance rates were 29.2% and 97%, respectively. Long-term, complete and partial pain relief were 93.9%, 83.1%, and 10.8%, respectively. The risk of pancreatic fistula was higher in the 8 mm group (P < 0.05), and 80% of the pancreatic fistula cases occurred in the <8 mm group. A shorter pain duration (P = 0.007), smaller MPD diameter (P = 0.04), and lower Izbicki pain score (P < 0.001) predicted long-term pain relief. Pain recurrence after initial remission occurred in 5 patients and was only related to pain duration (P = 0.02). Stone recurrence and pancreatic exocrine functional and endocrine functional deterioration occurred in 2, 5, and 11 patients, respectively. @*Conclusion@#Surgery provides excellent stone clearance, long-term pain relief, and acceptable postoperative morbidity. Using 8 mm as the criterion for drainage surgery can minimize the postoperative pancreatic fistula risk. Individualized and timely surgical treatment may improve the effect of surgery.

ABSTRACT

Hepatic ischemia-reperfusion injury is the most common complication after liver transplantation. Oxidative stress, autophagy, and inflammatory response caused by excessive reactive oxygen species production are significant steps that cause liver ischemia-reperfusion injury. What′s more, nuclear factor erythroid 2-related factor 2 is considered to be a major regulator of the antioxidant response, the PI3K-Akt-mTOR signaling pathway is considered to be an important pathway of autophagy, and the HMGB1-TLR4-NF-κB signaling pathway is considered to be a key signaling pathway which leads to inflammation. Based on the above signaling pathways and regulatory factor, this article shows that the antioxidant, anti-inflammatory and autophagy regulation effects of genes, molecules and drugs on hepatic ischemia-reperfusion cells, to explore the protective effects on hepatic ischemia-reperfusion cells.

ABSTRACT

Platelets,which are derived from the multifunctional hematopoietic stem cells in the hematopoietic system of bone marrow,are small pieces of cytoplasm which was partially exfoliated from the bone marrow megakaryotic cells,and play an important role in the physiological hemostasis and coagulation process.Tumor cells transfer biomolecules (such as RNA) to platelets by direct contact or exosomes release,resulting in changes in platelet precursor RNA.Through the effect of tumor cells and microenvironment,precursor RNA of platelet is spliced to mature RNA and then transformed into functional protein to responds to external stimulation,which is forming tumor-educated platelets.The detection of tumor-educated platelets of peripheral blood of patients is expected to be used in clinical tumor diagnosis.The novel liquid biopsy method can be a replacement or supplement for current tumor detection methods.Further study of the role of tumor-educated platelets in the diagnosis of tumors will provide a new theoretical basis for clinical diagnosis of tumors.
