Objective: The survival of colorectal cancer in Qidong City, Jiangsu Province from 1972 to 2016 was analyzed to provide a basis for the evaluation of prognosis and the formulation of prevention and control measures. Methods: Colorectal cancer data were obtained from the Qidong Cancer Registration and Reporting System, and the follow-up was up to December 31, 2021. The observed survival rate (OSR) and relative survival rate (RSR) were calculated by SURV 3.01 software, and the trend test was performed by Hakulinen's likelihood ratio test. The Joinpoint regression model was used to calculate the average annual percentage change (AAPC) of survival, and the ARIMA model was used to predict the trend of colorectal cancer survival. Results: There were 8 637 new cases of colorectal cancer in Qidong from 1972 to 2016. Dividing 1972-2016 into 9 periods at 5-year intervals, the 5-year OSR from 1972-1976 to 2012-2016 increased from 21.86% to 48.86%, and the 5-year RSR increased from 26.45% to 59.91%. The increasing trend of RSR was statistically significant (χ(2)=587.47, P<0.001). From 1972 to 2016, the survival rates of colorectal cancer in different sexes in Qidong were similar, and the 5-year RSR was 44.63% for men and 44.07% for women. Since the 1990s, the 5-year OSR and RSR for men have been lower than those for women. From 1972 to 2016, the 5-year RSR of colorectal cancer in Qidong was significantly improved in the 65-74 and ≥75-year-old groups, but the survival rate of the ≥75-year-old group was still the lowest (36.78%), followed by the 35-44-year-old group ( 43.04%). The time trend showed that the overall AAPC of colorectal cancer 5-year RSR in Qidong from 1972 to 2016 was 2.50% (t=16.45, P<0.001). The upward trend of different sexes was consistent, and the increase was greater in women (AAPC for males=2.18%, AAPC for females=2.54%, both P<0.05). The 5-year RSR of colorectal cancer in each age group showed an upward trend, and the AAPCs of the 35-44, 45-54, 55-64, 65-74, and ≥75-year-old groups were 1.54%, 1.83%, 2.00%, 3.51% and 4.35%, respectively (all P<0.05). The prediction results of colorectal cancer survival rate showed that the 5-year RSR of colorectal cancer in Qidong will increase to 71.62% by 2026. Conclusions: The overall survival rate of colorectal cancer patients in Qidong has been greatly improved, but there is still room for improvement. We should continue to pay attention to the early diagnosis and early treatment of colorectal cancer.

OBJECTIVE:To observe effect and safety of continuous renal replacement therapy (CRRT) combined with differ ent doses of xuebijing sepsis patients with acute kidney injury (AKI).METHODS:One hundred and four patients diagnosed as sepsis complicated with AKI were collected from ICU of our hospital during Jun.2012 to Aug.2015.They were divided into small-dose group,medium-dose group,large-dose group and control group according to random number table,with 26 cases in each group.Four groups received routine treatment.Small-dose group was given Xuebijing injection 50 mL added into 0.9％ Sodium chlo ride injection (NS) 100 mL,ivgtt,bid;medium-dose group was given Xuebijing injection 100 mL added into NS 100 mL,ivgtt,bid;large-dose group was given Xuebijing injection 100 mL added into NS 100 mL,ivgtt,qid.All patients were treated for 1 week.The levels of IL-6,TNF-α and hs-CRP were observed in 4 groups before and after treatment;renal function indexes as BUN,SCr and CysC,blood coagulation function indexes as PT,APTT and Fib were also observed as well as APACHE Ⅱ score and Marshall score.The occurrence of ADR were recorded during treatment.RESULTS:Ninety-five cases meeting the criteria were finally included in the study after 9 cases withdrew from the study,and there were 23,24,25,23 cases in small-dose group,medium-dose group,large-dose group and control group,respectively.Before treatment,there was no statistical significance in above indexes among 4 groups (P＞0.05).After treatment,the serum levels of IL-6,TNF-α,CRP,PT and APTT,APACHE Ⅱ score and Marshall score in 4 groups were all decreased significantly,while the serum levels of BUN,SCr,CysC and Fib were increased significantly;the improvement of above indexes in small-dose group,medium-dose group and large-dose group were all better than in control group,and the large-dose group was significantly better than the small-dose group and medium-dose group,with statistical significance (P＜0.05).There was no statistical signifi cance in the incidence of ADR among 4 groups (P＞ 0.05).CONCLUSIONS:Large-dose xuebijing combined with CRRT can effectively inhibit inflammatory reaction in sepsis patients with AKI,improves renal function and coagulation function,and dose not increase the risk of ADR.

A series of 5-amino-2-( benzylthio ) thiazole-4-carboxamide derivatives were designed and synthesized to discover novel compounds with anti-tumor activity. Compounds DDO-5401-DDO-5416 were synthesized using 2-amino-2-cyanoacetamide as the start material. The structures of the synthesized compounds were confirmed by IR, 1 H NMR and ESI-MS. The in vitro anti-tumor activities of the synthesized compounds were determined by MTT assay in HCT116 , HepG2 , A549 , MDA-MB-231 and MCF-7 cell lines. Target compounds showed good anti-tumor activity especially in A549 cell line. SAR study showed that electron donating groups were more favorable than electron absorption ones. Compound DDO-5413 exhibited noteworthy activity in MDA-MB-231 and MCF-7 cell lines with IC50 value lower than the positive reference dasatinib. It suggested that DDO-5413 might be the candidate for further investigation.

Glucocorticoid receptor (GR),a member of the steroid receptor superfamily,can mediate the signal pathway of ligands like glucocorticoids,regulate the transcription of target genes,and exert biological activity.GR is expressed in different degrees in three major kinds of urological malignant tumors including renal cancer,bladder cancer and prostate cancer.It also affects the metabolism of tumor cells,and is closely related to the occurrence,development and prognosis of tumors.GR provides an important clue for targeted therapy and endocrine therapy of urological malignant tumors.

Objective: To evaluate the patients′ survival and effectiveness of the live cancer screening for population at high risk for liver cancer in Qidong. Methods: According to the Expert Scheme proposed the Expert Committee of Early Detection and Early Treatment, China Cancer Foundation, diagnostical screening by using combined methods of alpha-fetoprotein and B ultrasound monitoring were carried out biannually in individuals with positive HBsAg who were screened from Qidong area. The evaluation indices of the effectiveness are task completion rate of screening, detection rate of liver cancer, early diagnosis rate, and treatment rate. The deadline of the follow-up for the surviving outcome was March 31, 2016. The life-table method was used to calculate the observed survival, and to make comparison and significant tests between survival rates in Group A (those found via repeated periodic screening) and Group B (those diagnosed without periodic screening). Results: Since 2007, 38 016 target population have been screened, and 3 703(9.74%) individuals with positive HBsAg were found. Except for 29 patients with liver cancer at the initial screening, 3 674 persons in the cohort were followed up; 268 patients with liver cancer were detected from the 33 199 person-times screening, with an annual detection rate of 1.61%. Of them, 186 patients were found in Group A(1.12%), in which 149 patients were the early cases, with an early detection rate of 80.11%; 167 out of 186(89.78%) patients received treatment after diagnosis. The incidence of liver cancer in this HBsAg (+ ) cohort of 25 452 person-years was 1 052.96 per 100 000 annually, 187 cases in males(1 488.45/100 000)and 81 cases in females(628.46/100 000). The 1-, 3-, 5-, and 8-year survival of all patients with liver cancer were 64.55%, 40.50%, 32.54%, and 19.65%, respectively. The 1-, 3-, 5-, and 8-year survival rates were 77.16%, 49.04%, 38.53%, and 24.25% in Group A, and were 36.25%, 21.21%, 21.21%, and 0% in Group B, respectively, with significant differences between two groups (P<0.05). Conclusion The findings show that screening of individuals at high-risk of development of liver cancer, with semiannual AFP and B ultrasound, according to the Expert Scheme, is effective not only in increasing detection rate but also in detecting liver cancer at early stage, and in improving patients′ survival as well.

Objective To compare the difference of ultrasound and digital subtraction anginography (DSA) in diagnosing carotid atheriosclerosis. Methods A total of 340 patients of ischemic cerebrovascular disease with carotid atheriosclerosis were examined with ultrasound and DSA. They were divided into cerebral infarction group (n=235) and transient ischemic attack (TIA, n=105), and also were divided into the young-aged group (n=54), middle-aged group (n=137) and old-aged group (n=149) by age. Results Both of the ultrasound and DSA found that the incidence of carotid artery stenosis in cerebral infarction was higher than that in TIA (P<0.05);the incidence that of carotid artery stenosis in old-aged group were higher than that in middle-aged and young-aged group (P<0.05), and in middle-aged group was higher than that in young-aged group. Taking DSA as standard, the accordance rate of ultrasound in diagnosing stenosis, clot and both of them were 89.39%, 80.85%, 87.15%, respectively. Conclusion Carotid artery ultrasound has high sensitivity in diagnosis of carotid atheriosclerosis. Either carotid artery ultrasound or DSA has advantages. With combination of two methods, there will be an important significance in the diagnosis, clinical treatment, assess before operation and follow-up after operation in patients with carotid atheriosclerosis.

Objective To investigate whether microRNA-34a (miR-34a) participates in lipopolysaccharide (LPS) mediated sepsis related renal function impairment via Kruppel-like factor 4 (KLF4). Methods Thirty healthy male Sprague-Dawley (SD) rats, weighing 180-200 g, were randomly divided into two groups: control group and model group, with 15 rats in each group. The SD rats from model group were injected with LPS 7.5 mg/kg to induce sepsis related renal function impairment model, the SD rats from control group were injected with normal saline. The serum creatinine concentration (SCr) and blood urine nitrogen (BUN) content was detected by multifunction biochemical analyzer; the morphological changes of renal tissue were observed by hematoxylin and eosin stain (HE) staining; the expression of miR-34a and KLF4 gene in plasma and renal tissue were detected by real-time quantitative reverse transcriptase polymerase chain reaction (qRT-PCR); the protein expression of KLF4 in renal tissue was detected by Western Blot; the target gene of miR-34a was verified by double luciferase reporter gene analysis. Results Compared with control group, inflammatory cell infiltration in renal tissue was increased in model group, the SCr and BUN were significantly increased [SCr (μmol/L): 142.5±10.6 vs. 46.4±5.6, BUN (mmol/L): 31.6±6.2 vs. 8.5±1.2, both P < 0.01], the gene expression of miR-34 in plasma and renal tissue were significantly increased (2 -ΔΔCt: 2.26±0.11 vs. 1.14±0.05 in plasma, 4.23±0.12 vs. 1.12±0.04 in renal tissue, both P < 0.01), the gene and protein expressions of KLF4 were significantly decreased [KLF4 gene (2 -ΔΔCt): 0.52±0.03 vs. 1.21±0.06, KLF4 protein (A value): 0.72±0.03 vs. 1.05±0.04, both P < 0.01], which indicated that kidney injury occurred in rats. Pearson correlation analysis showed that plasma miR-34a was positively correlated with SCr and BUN (r value were 0.678, 0.721, respectively, both P < 0.05). Double luciferase reporter assay confirmed that KLF4 was the target gene of miR-34a. Conclusion The miR-34a participates in LPS mediated sepsis related renal function impairment via KLF4.

Objective The application of nano-carbon tracer technique in radical antegrade modular pancreatosplenectomy (RAMPS) to treat malignant tumors of pancreatic body and tail.To investigate whether radical anterograde modulization of pancreatic body and tail combined with nano-carbon tracer technique is more beneficial to the prognosis of patients.Methods From January 2014 to September 2018,a retrospective analysis was performed in 48 patients in Linyi Central Hospital,all patients underwent RAMPS,all of whom were pathologically proved to be pancreatic carcinoma of the body and tail.Based on whether the nano-carbon lymph node tracer was performed during the operation,the patients were divided into two groups:nano-carbon group (nano-carbon lymph node tracing) and conventional operation group (no nano-carbon lymph node tracer).The differences between the two groups were analyzed,including operative time,intraoperative blood loss,postoperative complications (pancreatic fistula),postoperative hospitalization time,postoperative pathological lymph node status (number of dissection,number of positive lymph nodes,the positive rate of lymph node black staining in nano-carbon group) and survival time after operation.The measurement data were expressed as mean ± standard deviation (Mean ± SD),t-test were used for comparison among groups;Chi-square test was used for comparison of counting data,and Kaplan-Meier test was used for comparison of survival rate.Results There was no significant difference in the time of operation [(4.45 ± 0.59) h vs (4.41 ±0.65) h],the amount of blood lost during operation [(447.39 ± 109.51) ml vs (434.8 ± 76.38) ml] and the time of hospitalization after operation [(16.52 ± 4.12) d vs (16.56 ±2.92) d] between the two groups (P＞0.05).There were 1 case of pancreatic fistula in the nano-carbon group and 2 cases of pancreatic fistula in the convertional operation group,but the difference was not statistically significant (P =0.55).The number of lymph nodes dissected and positive lymph nodes in nano-carbon group were significantly higher than those in conventional operation group [(18.26 ± 2.49) vs (12.16 ± 2.19);(5.52 ± 1.50) vs (3.32 ± 0.85).The difference was statistically significant (P ＜ 0.05).The positive rate of lymph nodes in black stained lymph nodes (38.10％,96/252) was significantly higher than that in non-stained lymph nodes (18.45％,31/168),and the difference was statistically significant (P ＜ 0.05).The average survival time in the nano-carbon group [(25.48 ± 11.74) months] was significantly longer than that in the conventional operation group [(15.80 ± 11.64) months],and the difference was statistically significant (P ＜ 0.05).Conclusions It is safe,effective and feasible to treat malignant tumors of pancreatic body and tail by RAMPS combined with nano-carbon tracer technique.The positive rate of lymph node dissection and the detection rate of total lymph nodes are increased,and the prognosis of patients is improved,to improve the survival time of patients after operation is improved.
