Objective:To investigate the efficacy of fruquintinib in the treatment of advanced colorectal cancer, and to analyze the risk factors for all-cause death of fruquintinib.Methods:The clinical data of 82 patients with advanced colorectal cancer in the First Affiliated Hospital of Bengbu Medical College from December 2020 to April 2022 were retrospectively analyzed. The basic clinical data, efficacy and adverse reactions were recorded. The patients were followed up to October 2022, and all-cause death was recorded. Multivariate Logistic regression was used to analyze the risk factors of all-cause death in patients with advanced colorectal cancer treated with fruquintinib.Results:After treatment, partial remission was found in 9 cases, stable disease in 42 cases, disease progression in 31 cases. The objective remission rate was 10.98% (9/82), and the disease control rate was 62.20% (51/82). The incidence of adverse reactions was 75.61% (62/82), mainly hypertension and hand-foot syndrome. By the end of follow-up, 19 patients died and 63 survived. The incidences of body mass index (BMI)≥24 kg/m 2, lymph node metastasis, tumor located in the right colon and lactate dehydrogenase >200 U/L in all-cause death patients were significantly higher than those in survival patients: 36.51% (23/63) vs. 16/19, 39.68% (25/63) vs. 13/19, 44.44% (28/63) vs. 15/19 and 41.27% (26/63) vs. 14/19, and there were statistical differences ( P<0.01 or <0.05); there were no statistical differences in gender composition, age, smoking history, hypertension and postoperative complications between the two groups ( P>0.05). Multivariate Logistic regression analysis result showed that BMI≥24 kg/m 2, lymph node metastasis, tumor located in the right colon and lactate dehydrogenase >200 U/L were independent risk factors for all-cause death in patients with advanced colorectal cancer treated with fruquintinib ( OR = 9.275, 3.293, 4.687 and 3.985; 95% CI 2.440 to 35.265, 1.106 to 9.806, 1.398 to 15.715 and 1.277 to 12.430; P<0.01 or <0.05). Conclusions:Fruquintinib is effective in the treatment of advanced colorectal cancer. The BMI≥24 kg/m 2, lymph node metastasis, tumor located in the right colon and lactate dehydrogenase >200 U/L are independent risk factors for all-cause death in patients with advanced colorectal cancer treated with fruquintinib.

Objective:To investigate the prevalence of hyperuricemia (HUA), patients′ awareness of HUA, and related factors among elderly in community.Methods:The health check-up data of 6 897 residents aged over 65 years in Gumei Community of Shanghai were collected from January 2019 to January 2020. There were 1 156 subject with increased serum uric acid levels (HUA group) and 5 741 with normal uric acid levels (non-HUA group). The differences of clinical indicators between HUA group and non-HUA group were analyzed and the risk factors of HUA was determined by multivariate logistic stepwise regression. A questionnaire survey on the knowledge of HUA and the adoption of relevant health behaviors was conducted among HUA patients.Results:The overall prevalence was 16.8% (1 156/6 897) in this population. The prevalence in males was significantly higher than that in females[26.4%(842/3 195) vs. 8.5%(314/3 702), P<0.001); and the prevalence in females increased with age (χ 2=7.56, P=0.023). Body mass index(BMI), waist circumference(WC), total cholesterol(TC), triglyceride(TG), serum creatinine, alanine aminotransferase(ALT) and albumin/urine creatinine ratio(UACR) in the HUA group were significantly higher than those in the non-HUA group, while estimated glomerular filtration rate(eGFR) and high-density lipoprotein(HDL) were lower than those in the non-HUA group (all P<0.01). The prevalence of hypertension, decreased renal function, overweight or obesity, abdominal obesity, fatty liver and renal cyst in HUA group was significantly higher than that in non-HUA group (all P<0.01). High values of TG, low-density lipoprotein(LDL), WC, hypertension and fatty liver were risk factors for HUA( OR=1.14, 1.20, 1.03, 1.43, 2.19; P<0.01); while female gender, eGFR, HDL and glycosylated hemoglobin A1c(HbA1c) were protective factors for HUA( OR=0.32, 0.94, 0.65, 0.78; P<0.01). The questionnaire survey was conducted among 1 090 HUA patients, and the results showed that 73.2% (798 cases) were aware of the disease after the health check-up results released; only 30.9% (337 cases) knew the diagnostic criteria of HUA, 21.1% (230 cases) knew that HUA needed life-long follow-up care, 56.3% (614 cases), 49.2% (536 cases) and 47.9% (522 cases) thought that HUA should eat less seafood, broth and soya bean products, 17.0%(185 cases) were atcohol drinker and the awareness rates of above questions in patients with gout were higher than those in patients without gout ( P<0.05). Conclusion:The study shows that the prevalence of HUA among the elderly in Gumei community of Shanghai is high, and the HUA related knowledge levels and health behavior performance are not ideal, especially for HUA patients without gout, therefore health education should be strengthened for elderly residents in the community.

Objective: To evaluate the accuracy of endoscopic titanium clip localization combined with CT three-dimensional reconstruction for the control of incision margin in early gastric cancer under laparoscopy. Methods: A prospective analysis was made for gastric cancer whose lesions were located in the middle of the stomach and T stage was 1 to 2 from October 2017 to January 2019 at Department of Gastrointestinal and Pancreatic Surgery, Zhejiang Provincial People′s Hospital. Totally 25 patients were eventually enrolled in the study. There were 17 males and 8 females aging of (63.6±7.2) years (range: 48 to 77 years). All cases were treated with titanium clip localization under endoscope combined with CT three-dimensional(3D) reconstruction to construct a virtual panorama of gastric cavity and lesions, and to design surgical margins. Laparoscopic surgical resection was performed according to the surgical margins designed before operation. The distance from the gastric angle to the origin of the minor curvature of the incisional margin, the distance from the gastric angle to the the center of lesion and the distance of the upper incision margin were measured under three-dimensional CT reconstruction and under actual specimen. Paired t test was used to compare the three distances measured by two methods. Results: The measured distances from the gastric angle to the center of the lesion and the proximal incisional margin under 3D reconstruction CT were according to the measured values of actual specimens ((2.67±1.38) cm vs. (2.83±1.56) cm, t=1.51, P=0.14; (5.23±0.60) cm vs. 5 cm, t=1.93, P=0.07); the measured distances from the gastric angle to the origin of the minor curvature of the incisional margin under CT 3D reconstruction were different with the measured values of solid specimens ((5.94±0.94) cm vs. (6.37±0.90) cm, t=3.52, P=0.00). Conclusion The method of titanium clip localization combined with CT 3D reconstruction can provide a feasible laparoscopic localization method and incision edge solution for T1 to T2 gastric central cancer.

Nonalcoholic steatohepatitis (NASH) is an important pathological stage of nonalcoholic fatty liver disease characterized by hepatocyte fatty degeneration, liver injury, and liver inflammation and can further develop into liver cirrhosis and hepatocellular carcinoma. The NOD-like receptor family, pyrin domain-containing protein 3 (NLRP3) inflammasome is a multi-protein complex in cells and can induce cell apoptosis and expand inflammatory response by activating caspase-1 and releasing mature inflammatory factors such as interleukin-1β and interleukin-18. Recent studies have found that NLRP3 inflammasome may participate in the development and progression of NASH. Therefore, this article summarizes the role of NLRP3 inflammasome in NASH, so as to provide a theoretical basis for future research and treatment.

Liver cancer is a malignant tumor with the characteristics of high morbidity and mortality.However,the routine detection methods for the liver cancer such as imaging tests and pathological detection are with low specificity and sensitivity.And it's also hard to detect the condition of patients dynamically.Cell-free DNA (cfDNA) is the DNA fragment that is away from the extracellular and exists in the blood,which contains genetic information from the organism.The related disease information could be reflected on the cfDNA in patients with liver cancer,indicating that cfDNA has great potential in the screening,diagnosis,treatment and prognosis of liver cancer.The clinical applications of cfDNA can make up for the deficiency of existing detection methods and achieve noninvasive and dynamic monitoring of liver cancer.This article will present a review on the progress of clinical applications of cfDNA in liver cancer.

Objective To investigate the factors affecting the efficacy of leflunomide combined with medium/low dose corticosteroids in the treatment of progressive IgA nephropathy (IgAN).Methods Clinical and pathological parameters were collected retrospectively in patients of primary IgAN with proteinuria＞ 1.0 g/24 h and chronic kidney disease (CKD) stage 1-3 treated with leflunomide combined with medium/low dose corticosteroids in Ren Ji Hospital,School of Medicine,Shanghai Jiao Tong University from Jan 2005 to Dec 2010.According to the treatment effects,patients were divided into complete remission group and non-complete remission group.The biochemical and pathological indexes of the two groups were compared.Results A total of 42 patients were included.The remission rates at 3,6,9 and 12 months were 62％,64％,67％ and 74％,respectively.Seventeen (40.5％) and fourteen (33.3％) patients achieved complete and partial remission after one-year treatment,and the remission rate remained stable within one year after withdrawal of drugs.The 24hour proteinuria was 1.50 (0.67,2.66) g,which was significantly reduced compared with the baseline 2.44 (1.36,3.74) g (P ＜ 0.01).The decrease rate was 31.3％.There was a slight decrease in proteinuriawithin one year after withdrawal of drugs.Estimated glomerular filtration rate (eGFR) remained stable during the treatment and a year of follow-up.No serious adverse event was observed during the followup period.Among 31 responder patients,6(19.4％) patients relapsed.Logistic multivariate regression analysis suggested that the degree of renal interstitial inflammatory infiltration was an independent predictor of complete remission with one-year treatment of leflunomide combined with medium / low dose corticosteroids (HR=0.067,95％ CI 0.008-0.535,P=0.011).Conclusions IgAN treated with leflunomide and medium/low dose corticosteroids can achieve remission in early stage,and the remission rate remains stable after withdrawal of drugs.It is a safe option for the treatment of IgAN.Renal interstitial inflammatory infiltration is an independent predictor of complete remission.

Objective: To evaluate the safety and feasibility of laparoscopic radical antegrade modular pancreatosplenectomy(Lap-RAMPS) for left-sided pancreatic adenocarcinoma. Methods: Clinical data of total 12 patients underwent Lap-RAMPS for left-sided pancreatic adenocarcinoma at Department of Gastrointestinal and Pancreatic Surgery, Zhejiang Provincial People′s Hospital from March 2016 to August 2017 were reviewed retrospectively.There were 7 male patients and 5 female patients, with median age of 60.5 years old(47-68 years old). Abdominal enhanced CT, pancreatic MRI, PET-CT were performed on all patients to evaluate the lesion and exclude metastasis.Follow-up were done with out-patient clinic or telephone consultancy until October 2017. Results: All patients underwent pure Lap-RAMPS.The medium operative time was 250 minutes(180-445 minutes), and the blood loss was 150 ml(50-500 ml). The medium first flatus time and diet resumption time were 3.0 days(1-5 days) and 3.5 days(1-7 days) respectively.The medium postoperative hospital stay was 9 days(4-18 days). Morbidity occurred in 8 patients with gastric empty delay(n=1), bleeding(n=1), fluid collection(n=3). There was no mortality.The medium overall number of retrived lymph nodes was 15.6 and the positive rate was 41.7%. The R0 rate was 100%.The medium follow-up was 10 months.One patient was diagnosed as liver metastasis after 8 months and accepted chemotherapy.One patient died after 14 months for tumor recurrence and metastasis.Others survived without tumor recurrence or metasitasis. Conclusion Lap-RAMPS is safe and feasible with accepted oncological outcomes for selected left side pancreatic adenocarcinoma under skilled hands.
