Objective To explore the social economic factors related to depressive in patients with long-term hemodialysis.Methods A total of 122 patients with hemodialysis for more than 3 months from December 1st 2008 to February 1st 2009 in Dongfang Hospital and Wangjin Hospital,were divided into a depression group (41 cases) and a non-depressed group (81 cases).Informations such as economic status,social interaction,education,hobbies,etc were collected by questionnaire and the relationship between these factors and depression was analyzed.Results There was significant difference between the two groups in the factors of economic status,social interaction,education,and hobbies (x2 values were 14.671 、6.256、6.744、6.390,P＜0.05).There was no significant difference in the factors of gender,drinking,relationship of family,profession,the condition of housing,social status,seasons of born,and careers,etc (x2 values were 3.651、0.765、2.034、3.093、0.772、5.956、2.687、5.138,P＞0.05).Conclusion Thepatientswithpooreconomic,lower education,less social communication,fewer hobbies,and no smoking habits are easy to be depressive.

Objective Effects of fucoidan from Cladosiphon okamuranusa (CF)on mice bearing Siso were investigated. Methods Different concentrations of CF were given to mice bearing tumor by ig. The tumor weight, spleen index, thymus index and serum MDA content, serum SOD activity were detected by physical and biochemical methods. Results The growth of S180 tumor was inhibited significantly by CF in different concentrations. The inhibitory rate ranged from 27. 83% to 33. 97%. The highest inhibition rate occurred in the medium dosage. The spleen index, thymus index and leukocyte counts were not influenced obviously. The content of serum MDA was decreased remarkably and the activity of serum SOD was enhanced notably. Conclusion The mechanism of anti -tumor effects of CF may relate with its antioxidation.

Objective Statistically analyze the serum P53 antibody level in lung cancer patients to show its diagnostic values.Methods 53 cases of lung cancer and 32 cases of lung cancer after operation and chemotherapy are used as study group. 34 normal controls and 35 cases of lung benign disease were used as control group. All the serum P53 antibody levels of the testees are measured with a ELISA kit.Results In 53 cases of lung cancer group, the positive rate was 58.5% (31/53), while the average serum P53 antibody level was (4.551?6.074)IU/ml. In 32 cases of lung cancer after treatment including surgical and medical procedures, the positive rate was 25% (8/32), while the average serum P53 antibody level was (1.086?2.836)IU/ml. In 35 cases lung benign disease group, the average serum P53 antibody level was (0.163?0.097)IU/ml. In normal group, the average serum P53 antibody level was (0.162?0.08)IU/mL.The lung cancer group had statistical significance in comparison with the other three groups (P0.05).Conclusion The P53 antibody′s appearance is highly correlated with lung cancer. It can be used as an important marker of lung cancer and be beneficial to the differential diagnosis of lung lesions and the evaluation of the treatment.

Objective : To investigate equity of resource allocation in ophthalmology departments of medical institutions in Shenzhen City, so as to provide insights into the optimization of resource allocation in ophthalmology departments in Shenzhen City. Methods : The numbers of beds and ophthalmologists in ophthalmology departments of medical institutions in Shenzhen City were collected through the Shenzhen Health Statistical Yearbook 2019. The distribution of resources and equity of resource allocation were evaluated in ophthalmology departments of Shenzhen City using Lorenz curve and Gini coefficient. Results : There were 5.95 beds and 4.62 ophthalmologists in ophthalmology departments per 100 000 permanent residents in Shenzhen City in 2019. There were 13.35 beds and 9.51 ophthalmologists in ophthalmology departments per 100 000 permanent residents within the former special zone (Luohu, Futian, Nanshan and Yantian districts), and 2.17 beds and 2.13 ophthalmologists in ophthalmology departments per 100 000 permanent residents outside the former special zone (Guangming, Baoan, Longhua, Longgang, Pingshan districts and Dapeng New Area). The Gini coefficients of beds and ophthalmologists in ophthalmology departments were 0.348 and 0.243 by permanent residents in Shenzhen City, 0.386 and 0.386 within the former special zone and 0.086 and 0.012 outside the former special zone, respectively. The Lorenz curves of beds and ophthalmologists in ophthalmology departments were closer to the equity line outside the former special zone in relative to within the former special zone. Conclusion The gross number of beds and ophthalmologists remains to be increased in ophthalmology departments of medical institutions in Shenzhen City, and the equity of regional resource allocation is poor, which is mainly characterized by resource scarcity in ophthalmology departments outside the former special zone.

Objective To evaluate the effects of B7-H3 gene transfection on 18F-FDG uptake and 18F-FLT uptake in prostate cancer cells.Methods The absorption (A) values of untransfected prostate cancer(RM1) cells and B7-H3 gene-transfected RM1 (RM1-B7-H3) cells were detected at different culturing time points (0.5,1,2,3,4 and 5 d) with cell counting kit-8 (CCK-8) test.Cell cycle phase distribution of RM1 and RM1-B7-H3 cells was measured with flow cytometry.18F-FDG uptake of RM1 and RM1-B7-H3 cells was measured with γcounter and calculated under different conditions:5× 104-5× 106 cells; 0-11.0 mmol/L glucose; 20-120 min incubation in 37 ℃.18F-FLT uptake of RM1 and RM1-B7-H3 cells was measured in 1×106 cells under incubation for 100 min at 37 ℃.After administering anti-B7-H3 monoclonal antibody 4H7,18F-FDG uptake of RM1-B7-H3 cells was measured.The data were analyzed using one-way analysis of variance and two-sample t test.Results The A values of RM1-B7-H3 cells after being incubated for 1,2 and 3 d were higher than those of RM1 cells(1.59±0.23,2.26±0.15 and 2.01±0.60 vs 1.22±0.14,1.10± 0.09 and 1.04±0.15,t=3.923,19.228,4.467,all P＜0.01).There was no statistical significance between the 2 groups at other time points (t=-0.094,0.858,2.000,all P＞0.05).The ratios of RM1-B7-H3 cells in G1,S and G2/M phases were(32.96±2.56) ％,(39.11 ±2.57) ％ and (27.94±0.21) ％,respectively.The ratio of S phase in RM1-B7-H3 cells was higher than that in RM1 cells ((32.76±1.90)％,t=3.442,P＜ 0.05).18F-FDG uptake of the both cell lines decreased with the increase of glucose concentrations,while the uptake went up with the increase of cell number and incubation time.With the cell number of 1.0× 106,incubation time of 100 min and temperature of 37 ℃,the 18F-FDG uptake of RM1-B7-H3 and RM1 cells was (55.07±3.99)％ vs (44.16±3.60)％ (t=4.977,P＜0.01) ; and 18F-FLT uptake of RM1-B7-H3 and RM1 cells was (5.25±0.81)％ vs (3.33±0.64)％ (t=4.567,P＜0.01).After treated with antibody 4H7,18F-FDG uptake of RM1-B7-H3 cells ((45.36±2.92) ％) was lower than that of untreated group (F=10.001,P＜ 0.01).Conclusion B7-H3 gene transfection may promote the metabolism and proliferation of prostate cancer cells,and thereby increase the 18F-FDG uptake and 18F-FLT uptake.

Objective To investigate the correlated factors of pulmonary metastasis of hepatocellular carcinoma (HCC),so as to provide theoretical evidences for the prevention and treatment.Methods The clinical data of 862 patients with HCC who were admitted to the First Affiliated Hospital of Fujian Medical University from January 2008 to March 2012 were retrospectively analyzed.There were 107 patients with pulmonary metastasis.Factors including serum alpha fetoprotein (AFP) level,serum gamma-glutamyl transpeptidase (GGT) level,hepatitis B virus (HBV) infection,presence and treatment of intrahepatic tumor were analyzed to screen out relevant factors of pulmonary infection of HCC.Univariate and multivariate COX regression model analysis were performed for data analysis.Results The results of univariate analysis showed that high level of AFP (≥400 μg/L),ultra-high level of GGT (≥ 150 U/L),presence of HBV infection,the number of intrahepatic tumors ≥2,no radical resection (or radiofrequency ablation) for intrahepatic tumors,combining with tumor thrombi in the vessels,lymph node metastasis were risk factors of pulmonary metastasis of HCC (RR =1.986,3.653,0.365,3.675,0.252,0.379,0.352,P ＜ 0.05).The results of multivariate analysis showed that high level of AFP (≥400 μg/L),HBV infection,the number of intrahepatic tumors ≥2,no radical resection (or radiofrequency ablation) for intrahepatic tumors,combining with tumor thrombi in the vessels were risk factors of pulmonary metastasis of HCC (RR =2.391,3.462,3.425,3.396,2.418,0.638,P ＜ 0.05).Conclusions AFP ≥400 μg/L,HBV infection,the number of intrahepatic tumors ≥ 2,no radical resection (or radiofrequency ablation),tumor thrombi in the vessels and lymph node metastasis are risk factors of pulmonary metastasis of HCC.Anti-hepatitis virus treatment and early treatment are helpful for the prevention and treatment.

Objective To investigate the clinical efficacy of laparoscopic hepatectomy.Methods The clinical data of 258 patients who received laparoscopic hepatectomy at the First Affiliated Hospital of Fujian Medical University from March 2010 to January 2013 were retrospectively analyzed.There were 196 patients with primary hepatic cancer,45 with hepatic hemangioma,13 with hepatic focal nodular hyperplasia,2 with hepatic metastatic cancer,1 with carcinoma of gallbladder and 1 with hepatic hamartoma.All patients were followed up via phone call or out-patient examination till March 2013.Results A total of 142 patients received single hepatic segmentectomy,98 received multiple hepatic segmentectomy,18 received multiple lesions resection.Fifty-one patients received hepatic tumorectomy + cholecystectomy.All the operations were successfully done under laparoscope without conversion to the open surgery.The mean tumor diameter and the operation time were (5 ± 3) cm (range,1.0-11.5 cm) and (113 ± 56) minutes (range,50-310 minutes),respectively.Intraoperative hepatic portal occlusion was performed on 122 patients,and the time for hepatic portal occlusion was (15 ± 7)minutes.The volume of intraoperative blood loss was (211 ± 195)mL (range,10-650 mL),and blood transfusion was not needed.The capsule of the tumor was complete.The distance between the resection margin and the malignant tumor was above 1.5 cm,and there was no residual tumor in the resection margin.The hepatic function was back to the normal level in 1 week after the operation,and no patient had hepatic failure.The duration of postoperative hospital stay was (7.2 ± 1.3)days (range,5-10 days).One patient was complicated with bile leakage,6 with slight peritoneal effusion,and other patients had no postoperative complications.The rate of follow-up was 91.47％ (236/258),and the time of follow-up was (16 ± 10) months.A total of 199 patients with malignant hepatic tumors were followed up.During the follow-up,180 patients had tumor-free survival; 18 patients had postoperative tumor recurrence; 1 patient had omental metastasis and received surgical resection.Thirty-seven patients with benign hepatic tumor survived without complication during the follow-up.Conclusion Laparoscopic hepatectomy is effective for the treatment of hepatic tumors.Multiple hepatic inflow occlusion under laparoscope in a short time may improve the safety of surgery,without prolonging the recovery time of patients.

Objective To observe the effects of hepatic artery reconstruction in rat with orthotopic liver transplantation(OLT)on ultrastructure changes of intrahepatic biliary epithelial cells after ischemia reperfusion iniury and postoperative biliary complications. Methods Male SD rats were divided into sham operation group (SO),OLT with hepatic artery reconstruction group(HA)and OLT without hepatic artery reconstruction group (NA).The liver tissue samples were collected at 0.5,3,6,12,24,36,48 hours after ischemia reperfusion in both HA grouD and NA group.The uhrastructure of intrahepatic biliary epithelial cells was observed by transmission electron microscope,and the morphometric analysis by the computer image analysis system.The postoperative biliary complications were also observed.Results In HA group and NA group,the injury of intrahepatic biliary epithelial cells aggravated gradually along with the reperfusion.The uhrastructure changes,such as enlarged mitochondria,blurred or disappeared cristae and decreased number of microvilli,were most significant at 24 hours and then recovered gradually.The mitochondrial average area and average perimeter were increased and the mitochondrial numerical densitv was decreased gradually along with the reperfusion.At 24,36,48 hours,the mitochondrial average area and average perimeter in NA group were significantly greater than those in HA group(t=-3.566,-7.780,-4.730,-4.610,-2.599,-5.730,P＜0.05).The average numerial density of mitochondia in NA group was significantly less than that in HA group at 36,48 hours(t=-4.619,4.000,P＜0.05).The incidence rate of biliary complications in HA group is significantly lower than that in NA group(x2=4.286,P＜0.05).Conclusions Hepatic artery reconstruction in rat with OLT has an protective effect on the uhrastructure of intrahepatic biliary epithelial cells after ischemia reperfusion.It is beneficial to the recovery of intrahepatic bile duct epithelial cells and can reduce the incidence rate of biliary complications.
