Objective Inhibitor of growth 1 ( ING1 ) gene has been identified as a novel candidate of tumor suppressor gene .Over-expression of ING1 plays well-established roles in numerous cell processes ,inclu-ding DNA repair and cell apoptosis .Our study is to investigate the clinical significances of expression of ING 1 in colorectal cancer ( CRC) .Methods The mRNA level of ING1 in 82 matched samples comprising primary CRC and paired non-cancerous mucosa were detected and compared by quantitative RT -PCR.Then the correlations of mRNA level of ING1 with the clinicopathological characteristics and prognosis of patients with CRC were ana -lyzed.Results (1)In the same matched tissues,the expression level of ING1 was significantly higher in normal tissues than that in cancer tissues.(2)mRNA expression of ING1 was associated with certain clinical -pathologic variables such as tumor infiltrating level ,lymphatic metastasis,distant metastasis and advancing TNM stage .(3) We obtained the expression levels ratio of cancer tissue and normal tissue and found the lower ratio has a lower Disease-Free Survival(DFS)(P<0.0001).(4)ING1,as a candidate of tumor suppressor gene ,remained a sta-tistically-significant prognostic marker in the Cox regression analysis .Conclusion Down-regulation of ING1 may be correlated tightly with the occurrence and progression of sporadic colorectal cancer .Its expression level can be used to predict prognosis of CRC .
2.Dawn of light: opportunities and challenges in small cell lung cancer immunotherapy
Clinical Medicine of China 2022;38(1):1-4
Small cell lung cancer accounts for about 15% of all lung cancers, and is a highly invasive neuroendocrine tumor. smoking is a major risk factor. SCLC grows rapidly, has a high metastasis rate and has a poor prognosis. For more than 30 years, the treatment of SCLC has progressed slowly, until the emergence of immunodrugs in recent years, which have achieved certain efficacy in a wide range of patients.

Objective:To explore the difficulties and surgical decision of laparoscopic technique in patients with complicated hepatolithiasis.Methods:The clinical data of 13 patients with complicated hepatolithiasis who underwent laparoscopic hepatectomy at Department of Hepatobiliary Surgery, Affiliated Hospital of North Sichuan Medical College from December 2019 to December 2020 were collected. There were 3 males and 10 females with average age of 50.8 years (range: 14 to 67 years). All patients had upper abdominal pain and a history of cholecystectomy, 4 of them had fever.Seven cases underwent laparoscopic left hemihepatectomy+bile duct exploration, 2 cases underwent laparoscopic right hemihepatectomy+bile duct exploration, 2 cases underwent laparoscopic quadrate hepatectomy (liver 4B+Part 5)+hilar cholangioplasty+bile duct exploration, 2 cases underwent laparoscopic quadrate lobe resection (liver 4B+Part 5)+cholangioplasty+cholangiojejunostomy. All patients were re-examined with abdominal ultrasound and choledochoscope 3 months after operation.Results:The median operation time was 5.2 hours (range: 3.6-6.5 hours), blood loss was 278 ml (range: 120-580 ml). During the operation, 1 case had duodenal bulb injury, and the defect area was about 1.0 cm × 1.2 cm. After timely detection, the defect area was carefully evaluated and trimmed. Absorbable suture was used to suture duodenal bulb, and gastrojejunostomy was performed after repair. One case had small intestinal serosa injury, which was intermittently sutured and embedded with absorbable suture. All the patients recovered smoothly without death. Three months after the operation, 12 patients completed abdominal ultrasound and T-tube sinus choledochoscopy. Residual stones were found in 3 patients, stones were removed in 2 patients by T-tube sinus choledochoscopy 3 months after the operation, 1 patient was still in the recovery period (within 3 months after surgery). No residual stones were found in the remaining 10 patients.Conclusion:The three key laparoscopic techniques in operation of complex hepatolithiasis: adhesiolysis and porta hepatis exposure, laparoscopic hepatectomy, and laparoscopic choledochojejunostomy are very important.

Objective To explore the CTV to PTV external expansion boundary and the effect of the dose of normal lung tissue under different fixed modes by a comparative analysis of combined body position and thermoplastic film fixed set-up error of radiation therapy for lung cancer. Methods From October 2016 to March 2018, the patients who received chest radiology at the Tangshan people's hospital were enrolled as subjects retrospectively divided into two groups, including 50 patients with lung cancer radiotherapy with combined body position fixation, and 40 patients with lung cancer with thermoplastic film fixation. The two groups of patients drew the target areas in accordance with the unified standard, and the set-up error of left and right, up and down, front and rear ( x, y, z axis) were recorded respectively after 1 time/week cone CT( CBCT) matched with the planned CT image and analyzed by t test. According to the MPTV =2. 5Σ+0. 7δ, CTV to PTV external expansion boundary in the combined body position group were calculated. And the V5、V20 and V30 of two groups of patients were calculated and analyzed by TPS system. Results The set-up error of the combined body position group and thermoplastic film group were respectively (1. 00 ± 0. 58) mm and (3. 28 ± 0. 43) mm on the x axis, (1. 42 ± 0. 28) mm on the y axis and (4. 03 ± 0. 41) mm, (1. 06 ± 0. 44) mm and (3. 18 ± 0. 34) mm on the z axis. The set-up errors of the two groups were statistically significant on x, y and z axis( t= -20. 740, -35. 596, -25. 015,P<0. 05). There was no significant difference in set-up errors between the central and peripheral lung cancer patients and between left and right lung cancer patients(P>0. 05). Through the MPTV =2. 5Σ+0. 7δ, CTV to PTV external expansion boundary in the combined body position fixation group was 2. 906 , 3. 746 and 2. 958 mm on x, y and z axis respectively. The comparison between group A and B showed that the mean values of V5 , V20 and V30 in group B were reduced by 1. 5%, 3. 1% and 4. 8% respectively compared with group A. Conclusions The combined body position technique can improve the accuracy of lung cancer patients after radiation therapy,and further reduce the boundary of CTV to PTV, which is of certain value to reduce the occurrence of radiation pneumonitis.

Objective To confirm previous effort to identify type 2 diabetes susceptibility genes in a Northern Chinese population by conducting a new genome scan with both an increased number of type 2 diabetes families and a new set of microsatellite markers within the previously localized regions. Methods A genome scan method was applied. After multiplexed PCR, electrophoreses, genescan and genotyping analysis, we obtained size information for all loci , and then a further study was done by both parametric and non-parametric linkage analysis to investigate the P values and Z values of these loci. Results We surveyed 34 microsatellite markers which distributed within 5 regions along chromosome 1, and a total of 12?000 genotypes were screened. Evidence of linkage with diabetes was identified for 8 of the 34 loci. All P values of the 8 loci were lower than 0.05, and the highest Z value was 2.17. A very interesting finding is that all 5 markers at the p- terminal 1p36.3-1p36.23 region, spanning a long range of 16.9?cM, were identified to have a low P value of less than 0.05, which suggests that this region may contain multiple susceptibility genes. Regions 4 and 5 also confirmed the previous findings, and we narrowed these two regions to a 2.7?cM and 2.5?cM regions, respectively. Conclusions We further confirmed the results gained in the previous genome-wide scan using an increased number of NIDDM families and a new set of microsatellite markers lying within the initially localized regions. The fact that all 5 loci at the p- terminal region displayed a low P value of less than 0.05 suggests that more than 1 susceptibility gene may reside in this region.

BACKGROUND/AIMS: Gastrointestinal (GI) symptoms may develop when we fail to adapt to various stressors of our daily life. Central oxytocin (OXT) can counteract the biological actions of corticotropin-releasing factor (CRF), and in turn attenuates stress responses. Administration (intracerebroventricular) of OXT significantly antagonized the inhibitory effects of chronic complicated stress (CCS) on GI dysmotility in rats. However, intracerebroventricular administration is an invasive pathway. Intranasal administration can rapidly deliver peptides to the brain avoiding stress response. The effects of intranasal OXT on hypothalamus-pituitary-adrenal axis and GI motility in CCS conditions have not been investigated. METHODS: A CCS rat model was set up, OXT 5, 10, or 20 μg were intranasal administered, 30 minutes prior to stress loading. Central CRF and OXT expression levels were analyzed, serum corticosterone and OXT concentrations were measured, and gastric and colonic motor functions were evaluated by gastric emptying, fecal pellet output, and motility recording system. RESULTS: Rats in CCS condition showed significantly increased CRF expression and corticosterone concentration, which resulted in delayed gastric emptying and increased fecal pellet output, attenuated gastric motility and enhanced colonic motility were also recorded. OXT 10 μg or 20 μg significantly reduced CRF mRNA expression and the corticosterone concentration, OXT 20 μg also helped to restore GI motor dysfunction induced by CCS. CONCLUSION: Intranasal administration of OXT has an anxiolytic effect and attenuates the hypothalamus-pituitary-adrenal axis in response to CCS, and gave effects which helped to restore GI dysmotility, and might be a new approach for the treatment of stress-induced GI motility disorders.

Objective:To evaluate the teaching effect of Emergency Nursing practice course using scenario simulation teaching combined with formative assessment. Methods:The subjects were selected from vocational nursing students of Batch 2015 (control group, n=49) and Batch 2016 (intervention group, n=40). The control group adopted the scenario simulation teaching method, and the intervention group added formative assessment on the basis of simulation teaching. The end-of-term theoretical scores of Emergency Nursing and the scores of students' general self-efficacy scale were used as evaluation tools. SPSS 22.0 statistical software was used for data processing and analysis. Results:The scores of the intervention group (85.20±8.05) were higher than those of the control group (79.73±8.46), with statistical significance ( P<0.05). The scores of self-efficacy in both groups were improved, while the scores of the control group after the course (2.68±0.42) were higher than those before the course (2.61±0.47), but there was no statistical significance. The scores of the intervention group after the course (2.78±0.43) were higher than those before the course (2.62±0.43), with statistical significance. Conclusion:The application of scenario simulation teaching combined with formative assessment in the practical course of Emergency Nursing can be helpful to improve students' self-efficacy and comprehensive ability of first aid.

Objective? To explore the effects of enhanced recovery nursing on early postoperative vein thromboembolism (VTE) risk after pancreaticoduodenectomy (PD). Methods? Using convenience sampling method, the 45 cases of PD patients with traditional nursing methods from September 2016 to March 2017 were assigned as the control group, and the 66 cases of PD patients with enhanced recovery nursing from March 2017 to June 2018 were assigned as intervention group. The plasma D-dimer level before operation, immediately after operation, and in different postoperative days (POD): POD1, POD2, POD3 and POD7 were collected. The D-dimer level and the incidence rates of symptomatic VTE were compared between two groups. Results? The D-dimer values of the intervention group immediately after surgery, POD1, POD2, POD3 and POD7 were (2.74±2.31), (3.31±2.03), (3.98±3.10), (4.30±2.89) and (7.46±3.90) mg/L·FEU. The D-dimer of the control group at each postoperative time point were (2.88±1.92), (3.77±2.72), (4.37±2.70), (4.08±1.81) and (6.85±4.07) mg/L·FEU. The overall D-dimer value of the two groups showed an upward trend after operation,but there was no significant difference between two groups (P>0.05). Repeated measures analysis of variance showed that there were no differences in between-group effect (F=0.03, P=0.87) or interaction effect (F=1.01,P=0.38) of D-Dimer, while the difference in intra-group effect was statistically significant (F=108.28, P< 0.05). There was no statistical significance in the difference of the incidence rates of symptomatic VTE between two groups (χ2=0.87, P> 0.05). Conclusions? The early postoperative VTE risk after PD gradually increased, and the enhanced recovery nursing show no significantly advantage in VTE risk reduction after PD compared to traditional methods.
