In the past decades, epidemiological trends of the gastric cancer and esophagogastric junction (EGJ) cancer have changed all over the world. The morbidity and mortality of gastric cancer is on the decline, while the incidence and mortality of EGJ cancer is on the rise. This article summarizes the pathological types and the descriptive epidemiology, including the incidence, mortality, survival rate and its tendency in different gastric cancers and EGJ cancer. It also discusses the influencing factors of gastric cancer and EGJ cancer including environmental and genetic factors, which provides new ideas for the further study of the two kinds of cancers.

Objective To observe how brain death affects the hepatic morphology and function of pigs and explore the roles of NF-κB. Methods Under general anaesthesia twelve healthy pigs were allocated randomly to two groups:control group(6 pigs),with non-inflacted Foley balloon catheter placed in the cerebral ventricle for 24 h,and brain death group,6 pigs,with estabhshment of brain death for 24 h.The serum and hepatic tissues in the same locus were taken at 6 h,12 h,and 24 h after the initial conformation of brain death.AST and ALT were determined by automatic biochemistry analyzer.IL-1βwas determined by ELISA.The NF-κB mRNA was determined by Real-time PCR and the NF-κB p65 by immunohistochemistry. Results The AST,ALT,IL-1β in serum,the NF-κB mRNA and the NF-κB p65 in hepatic tissues in brain death group were higher than those in control group and they all increased with the time(P<0.05).In brain death group,hepatocytes were edematous lightly after 12 hours,and the swelling progressively deteriorated after 24 hours,but there were no necrosis. Conclusion The activated NF-κB by brain death promoted the synthesis and release of inflammatory mediators,resulting in the hepatic dysfunction.

Objective:To evaluate the clinical efficacy and safety of SpyGlass-guided laser lithotripsy for large common bile duct (CBD) stones with diameter>2 cm.Methods:From August 2015 to August 2018, a total of 157 patients with large CBD stones at the First Affiliated Hospital of Shandong First Medical University who met the inclusion criteria were randomly divided into SpyGlass group ( n=78, underwent SpyGlass-guided laser lithotripsy) and laparoscopic common bile duct exploration (LCBDE) group ( n=79, underwent LCBDE) by using random numbers. Non-inferiority test was used for rates of one-time stone removal and total stone removal, and the non-inferiority margin was set to 10%. The transform rate, incidence of short-term complications, hospital stay, and quality of life (assessed by the gastrointestinal quality of life index) were compared between the two groups. Results:The total success rates of stone clearance were 92.3% (72/78) and 96.2% (76/79) in the SpyGlass group and LCBDE group, respectively ( P=0.023), with valid non-inferiority hypothesis. The one-time stone removal rates were 83.3% (65/78) and 96.2% (76/79), respectively ( P=0.124), with invalid non-inferiority hypothesis. There were no significant differences in the incidence of transform [7.7% (6/78) VS 3.8% (3/79), P=0.294] or short-term complications [5.1% (4/78) VS 10.1% (8/79), P=0.246] between the two groups. Compared with the LCBDE group, the SpyGlass group had a shorter hospital stay (5.65±0.94 d VS 8.84±1.54 d, P=0.001) and higher scores of gastrointestinal quality of life index (1 month after operation: 99.85±4.36 VS 91.51±5.47, P=0.001; 3 months after operation: 131.24±3.32 VS 112.32±7.77, P=0.001). Conclusion:For large CBD stones, the efficacy of SpyGlass-guided laser lithotripsy is not inferior to LCBDE, and it is less invasive. In the future, SpyGlass-guided laser lithotripsy could be an important option for the treatment of large CBD stones.

Objective To study the efficacy and the safe dosage of high intensity focused ultrasound (HIFU) ablation in pancreatic cancer.Methods From November 2010 to May 2013,21 patients with advanced pancreatic cancer were treated by HIFU at the First Affiliated Hospital of Zhengzhou University.These patients who were randomly divided into two groups (10 and 11 patients respectively),were given a low-power (100~249 W) treatment and a high power (250 ~350 W) treatment.These two groups of 21 patients received a total of 25 times of HIFU treatment (3 patients received twice of low-power treatment,while 1 patient received twice of high-power treatment).The two groups were compared by analyzing the treatment parameters (average power,total treatment time,treatment total energy,treatment volume,etc.) and volume of tumour response as shown on postoperative imaging (CT or MRI) examinations.Also,the complications,degree of pain relief and survival were compared.The energy efficiency factor (EEF) and the ablation ratio were calculated.A preliminary study was conducted on the relationship of the ultrasound dose and the ablation effect of HIFU treatment for pancreatic cancer.Results (1) The EEF of the high-power group (≥250 W) and the low-power group (< 250 W) were (10.39 ± 5.71) J/mm3 and (21.62 ± 9.81) J/mm3,the former group was significantly lower than the latter group (P <0.05) ; the ablation ratio of the high-power group was higher than the low-power group,(91.52 ± 4.18)% versus (51.59 ± 7.66)% respectively,the difference was statistically significant (P < 0.001).(2) The efficiency factor and the ablation volume for the HIFU treatment showed a linear trend,and both were negatively correlated (Pearson correlation coefficient r =-0.485,P < 0.05).(3) There was no serious complication after the HIFU treatment.In the low-power group,six of ten patients were alleviated of his pain (60%) ; the CA19-9 decreased in four of ten patients after HIFU treatment (40%).In the high-power group,nine of eleven patients were significantly relieved of pain after treatment (82%),the CA19-9 decreased in five of nine patients after HIFU treatment (56%).(4) On Kaplan-Meier survival analysis,HIFU treatment of patients with pancreatic cancer,the median survival was 8 months and 9 months in the low-power group and high power group,respectively (Log-rank test x2 =0.05,P =0.944).Conclusion During HIFU treatment of patients with pancreatic cancer,if the ultrasound power was between 250 W and 350 W,there was a higher proportion of tumor ablation,but with no serious complications.Thus,this dose was safe.

AIM: To investigate hemodynamic alterations of retrobulbar vessels in proliferative diabetic retinopathy ( PDR) patients with anterior segment neovascularization, before and 3mo after vitrectomy combined with panretinal photocoagulation and to explore the clinical significance.
●METHODS: Color Doppler flow imaging ( CDFl ) was used for measurement of blood flow velocities and resistive indexes ( Rl ) of the ophthalmic artery ( OA ) , short posterior ciliary arteries ( sPCA ) and central retinal artery ( CRA ) in 21 eyes of 21 PDR patients with anterior segment neovascularization. CDFl parameters were obtained before and 3mo after vitrectomy combined with panretinal photocoagulation ( PRP) .
● RESULTS: Peak systolic velocity ( PSV ) and end diastolic velocity ( EVD ) of CRA were significantly increased after surgeries, Rl were decreased significantly (P<0. 05). Parameters of sPCA and OA have no change after surgeries (P>0. 05).
●CONCLUSION: Vitrectomy combined with panretinal photocoagulation might increase the velocity of CRA, decrease Rl and improve ocular blood supply postoperatively. lt may delay or prevent the process of neovascular glaucoma.

Olfactory neuroblastoma is a rare malignant tumor. Although multiple therapeutic modalities including surgery, radio-therapy, or chemotherapy could be used in patients with olfactory neuroblastoma, no standardized treatment has been achieved. This re-view introduces a case of adult olfactory neuroblastoma treated by a multiple disciplinary team in Tianjin Medical University Cancer In-stitute and Hospital. This review also aims to explore a complete set of diagnostic and treatment practices for the benefit of future pa-tients.
