ObjectiveTo investigate the effect on improving immune function by hemofiltration combined with hemoabsorption in septic patients with low human leukocyte antigen DR (HLA-DR) expression.Methods A prospective randomized controlled trial was conducted. Sixty sepsis patients aged over 18 years, with HLA-DR expression lower than 30% were enrolled, and they were randomly divided into experimental group and control group, n = 30 in each group. The patients were treated with standard operating procedure for sepsis, and hemofiltration combined with hemoabsorption were added in addition in the experimental group within 1-3 days. The continuous veno-venous hemofiltration (CVVH) mode was performed, with former dilution volume 4 L/h, and the hemofilter HF2000 was carried out with blood absorber HA-330H. The expression of HLA-DR in peripheral blood mononuclear cells was determined before the treatment and 3, 5, 7 days after treatment. Acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, duration of mechanical ventilation, length of intensive care unit (ICU) stay, and 28-day survival rate were evaluated in both groups.Results The HLA-DR expression before treatment in experimental group and control group was both lower than 30%, and there was no statistical difference [(25.9±7.3)% vs. (26.4±6.7)%,P>0.05]. The HLA-DR expression at 3, 5, 7 days after treatment in experimental group was gradually increased, and it was significantly higher than that of the control group [3 days: (38.9±8.6)% vs. (29.3±7.1)%, 5 days: (42.7±9.2)%vs. (31.4±6.5)%, 7 days: (40.9±8.5)% vs. (29.4±6.7)%, allP< 0.05]. There was no significant difference in APACHEⅡ score before treatment between experimental group and control group (22.4±5.3 vs. 21.7±6.2,P>0.05). APACHEⅡ score at 3, 5, and 7 days after treatment was gradually decreased in experimental group, and it was obviously lower than that of the control group (3 days: 18.6±3.6 vs. 20.5±4.3, 5 days: 15.8±3.9 vs. 21.1±4.4, 7 days: 14.9±4.2 vs. 19.8±3.7, allP< 0.05). Compared with the control group, the duration of mechanical ventilation (days: 13.3±3.4 vs. 19.8±3.7,t = 6.432,P = 0.003) and length of ICU stay (days: 20.7±3.9 vs. 26.8±4.7,t = 5.452, P = 0.006) in experimental group were significantly shortened, and the 28-day survival rate was significantly elevated (83.3% vs. 73.3%,χ2 = 3.121,P = 0.016).Conclusion Hemofiltration combined with hemoabsorption can improve the expression of HLA-DR in sepsis patients with low expression of HLA-DR, and it can improve immune function and prognosis of sepsis patients in certain degree.

Objective To evaluate whether an early change in 18F-fluorodeoxyglucose (18F-FDG) uptake can predict tumor response to epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) and prognosis in patients with non-small cell lung cancer (NSCLC). Methods From August 2009 to April 2015, 22 patients with NSCLC who were eligible to EGFR-TKI treatment were enrolled. PET-CT scan was performed before (baseline) and 1 month after EGFR-TKI administration. Up to 5 hottest single tumor lesions (no more than 2 per organ) were considered to be target lesions. Maximum standardized uptake values (SUVmax) were measured, and post-treatment percentage changes in SUVmax (ΔSUV%) were calculated. PET responses were classified using PET response criteria in solid tumors (PERCIST). Then conventional CT scan was performed every 2 months for follow-up. Kappa statistic was used to compare agreement between the RERCIST recommendations-based therapeutic response evaluation and those based on RECIST1.1 criteria. Fisher exact test was used to compare the probability of disease progression in the early metabolic response and non-response groups. Predictive accuracy of ΔSUV% with respect to response or non-progression at CT scan was evaluated by ROC analysis. Progression-free survival (PFS) was determined by Kaplan-Meier survival analysis, and between-group comparison was performed by log-rank test. Results After 1 month of EGFR-TKI treatment, 12 patients (55%) showed partial metabolic response (PMR), 6 (27%) had stable metabolic disease (SMD), and 4 (18%) had progressive metabolic disease (PMD). There was a moderate agreement(Kappa=0.506,P<0.05) between PET response at 1 month based on PERCIST recommendations and CT response at 3 months according to RECIST 1.1. Non-progression was significantly more frequent in patients with an early PMR (χ2=11.941, P=0.005). Progression had been confirmed later during therapy in all patients with PMD . By using ROC analysis, the area under the curve for prediction of response was 0.906 (95% CI, 0.766—1.000; P=0.002), corresponding to a sensitivity of 88.9% and specificity of 84.6% at a cut-off of 40.36% in ΔSUV%. Using a cut-off value of 25.84% in ΔSUV%, highΔSUV% group (ΔSUV% ≥ 25.84%) had significantly longer PFS than low ΔSUV% group (ΔSUV%<25.84%). Conclusion Early assessment of PET-CT at 1 month of EGFR-TKI treatment could be useful to predict tumor response and clinical outcome in patients with NSCLC.

To explore the efficacy of managing benign prostatic hyperplasia (BPH) by family doctor system service in a local community.Among 132 BPH patients recruited from January 2012 to December 2013,74 of them received family doctor system service while the remainder medications only.After 6 months,international prostate symptom score (10.3 ± 5.6) and quality-of-life (2.98 ± 0.95) significantly improved in management group versus control group.And there were significant statistical differences (P ＜ 0.05).The intervention management of family doctor system service is effective for improving the symptoms and quality-of-life of BPH patients.

Objective To compare the efficacy of stents 7 F and 10 F in drainage of pancreatic pseudocyst via EUS-FNA.Methods A retrospective analysis of patients with pancreatic pseudocyst who received endoscopic ultrasonography guided puncture drainage by using 7 F and 10 F double pigtail plastic stent respectively in Drum Tower Hospital of Nanjing University Medical School from 2010 to 2014 was conducted.Patients' hospitalization period, the time for 50％ cyst reduction, removal time, infection rate, and recurrence rate were compared.Results Twenty three patients with pancreatic pseudocyst were included, among whom 14 were male and 9 were female.The age ranged from 13 to 70 with an average of 45.1 years.Eleven patients were treated with 7 F pigtail plastic stents whereas 12 patients with 10 F pigtail plastic stents.All patients were treated with additional 8.5 F joint nose cyst drainage.Four cases in 7 F group got fever, 3 of whom were successful in anti-infection and 1 failed, having to change the stent.One case (9.1％) relapsed without symptoms after 52 months during the follow-up and received no intervention.Five cases in 10 F group got fever, 4 of whom were successful in anti-infection and 1 failed, having to change the stent.One case (8.3％) was identified as mild hemorrhage, and replantation needed to be performed in 1 case (8.3％) because stent was found to slip after 12 days.Two cases (16.7％) relapsed without symptoms after 11 and 24 months respectively and no intervention was received.There was no significant difference in patients' age, cyst size, removal time, infection rate and recurrence rate between the two groups.However, patients in group 10 F had a markedly shorter hospitalization period and time for cyst reduction by at least 50％ than those in group 7 F (P ＜ 0.05).Conclusion 10 F double pigtail plastic stents can drain the cyst faster, shorten the hospital stay, but there is no significant difference in infection or recurrence rate of cyst compared with 7 F stents.

Objective To analyze the overall deployment of Class-A large medical equipments in China.Methods Data of Class A large medical equipments deployed from 2007 to 2015 were collected and classified regionally,for the purpose of measuring the overall deployment,growth level and plan performance.Results There were 403 large medical equipments in China,a rapid rise of deployment,yet still far below developed countries in terms of per capita deployment.Regional differences were significant.With PET-CT as an example,the plan performance in the east(92.19%)was much higher than the west of China(68.57%);plan performance of Class-A equipments was better,conducive to regulating the increase and distribution.Conclusions The deployment level of Class-A equipments in China is low in general,and calls for better regulation regardless of the planning and management progress.

Objective To investigate the clinical efficacy of combination therapy of ambroxol with vibration? expectoration machine on ventilator-associated pneumonia Methods A total of 96 patients from the Department of Critical Care Medicine were selected and randomly divided into 3 groups:control group,ambroxol group and ammonia ambroxol + vibration expectoration machine group (n=32,each).The ventilator-associated pneumonia (VAP) was randomly divided into three groups (n =32,each).All patients were treated with conventional therapy including anti-inflammatory,suction,airway humidification,nutritional support.On this basis,ambroxol group was given ambroxol 30 mg in 100 ml normal saline,intravenously dripped 3 times a day.On the basis of treatment in the ambroxol group,ammonia ambroxol + expectoration machine were given G5 vibration expectoration machine to expectorate sputum 2 times every other day.Results There were significant differences in acute physiology and chronic health evaluation (APACHE Ⅱ),PaO2/FiO2,respiratory rate (RR),heart rate (HR) before versus after the treatment of the three groups (F =5.736,9.432,6.361,5.862,respectively,all P＜0.05).After treatment in the three groups,APACHE Ⅱ,PaO2/FiO2,RR and HR showed statistically significant differences inter-group among three groups (F=4.674,8.665,7.351,6.562,respectively,all P＜0.05).Clinical effective rates of the three groups were 71.9％,84.4％,93.8％ respectively,and showed statistically significant differences inter-group among three groups (all P＜0.05).Conclusions Combination therapy of ambroxol and vibration expectoration machine shows significant effects on VAP,and it is better than ambroxol alone.

Objective To evaluate the efficacy and safety of endoscopic therapy in the treatment of symptomatic pancreatic divisum (PD).Methods Data of 8 patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) with the diagnosis of pancreas divisum at our institution from June 2006 to June 2013 was retrospectively analyzed.Results The patients were identified as pancreatic divisum with 28 ERCP procedures.All patients received stent placement,7 underwent minor papilla sphincterotomy,6 pancreatic duct stricture dilatation,and 1 stone extraction.Post-endoscopic retrograde cholangiopancreatography pancreatitis occurred in 1 patient,and no other complications occurred.After a follow-up of 2-47 months,1 patient died of pancreatic carcinoma,3 patients removed the stents,3 patients were followed up regularly,and 1 was unavailable for the interview.The episode of chronic pancreatitis and the extent of abdominal pain decreased after the operations.Conclusion Endoscopic therapy is effective and safe for the pancreatic divisum patients.It can reduce the episode of chronic pancreatitis and relieve the chronic abdominal pain in PD patients with low incidence of complication.

Objective To investigate the feasibility and plan quality of the image-guided volumetric modulated arc therapy (VMAT) based voluntary deep exhale breath-holding technique in the stereotactic ablative body radiotherapy (SABR) for liver tumors.Methods Fifteen patients with liver tumors were involved in this study.All patients were immobilized with voluntary deep exhale breath hold (vDEBH) combined with real-time position management (RPM) respiratory gating system.Treatment was planned using VMAT with 2 modified partial arc and re-planned using intensity modulated radiation therapy (IMRT) technique for comparison.Dosimetric parameters were calculated for plan quality assessment.Quality assurance studies included absolute dose and multiple planar dose verifications,total monitor units and delivery time analysis.Daily cone beam computed tomography imaging was used to verify the motions.Results There were no significant dosimetric differences between VMAT and conventional IMRT plans (P ＞0.05).Both techniques were able to minimize doses to organs at risk including normal liver,kidneys,spinal cord,and stomach.However,the average monitor units with VMAT were significantly lower 28.1％ than those with IMRT(t =3.064,P ＜0.05).The average beam-on time in VMAT plans was 31.6％ shorter than that in IMRT plans(t =2.278,P ＜ 0.05).Conclusions The utilization of VMAT in the treatment planning of SABR for liver tumors under breath control mode has better dosimetrics.In comparison to conventional IMRT plans,VMAT plans have higher efficiency and feasibility.

Objective To analyze the clinical features of patients with IgG4-associated biliary and pancreatic diseases,and to improve the understanding of these diseases.Methods Nine cases of patients with IgG4-associated pancreatitis and cholangitis were analyzed retrospectively,which included clinical manifestations,serological examination,imaging test,pathology,treatment and prognosis.Results Of the 9 patients,8 were male,1 was female,the average age was 61 years old.Four cases were presented with jaundice,2 cases with jaundice and abdominal pain,2 cases with abdominal pain,and 1 case with diabetes.Serum IgG4 levels were 3.46-21.3 g/L (mean 9.743 g/L) in 6 cases,and which were higher than normal value,3 patients did not undergo blood test of IgG4.Nineteen auto-antibodies (including ANCA) were all negative in 9 cases.CA19-9 was increased in 4 cases.CT manifestations showed 5 cases with low density pancreas mass (2 cases with biliary tract dilatation);1 case had pancreas swelling with dilatation of bile duct,and 2 cases with bile duct dilatation only,and CT findings in 1 case were negative.Four patients underwent EUS-FNA,and EUS features included hypoechoic lesions without peripancreatic lymph nodes.FNA results indicated 2 cases with IgG4 related chronic inflammation,2 cases with chronic inflammation with negative IgG4.Seven cases were confirmed to have IgG4 related pancreatitis,and 2 cases with IgG4 related cholangitis.Six patients received glucocorticoid treatment,and the dose ranged from 8-40 mg;3 patients underwent surgery and the surgical pathology indicated IgG4 positive plasma cell.Follow-up showed the serum IgG4 returned to normal,clinical symptoms improved remarkably,and pancreatic mass decreased.Conclusions IgG4 positive plasma cell infiltration is the main feature of IgG4-associated cholangitis and pancreatitis.The diagnosis should combine image,serology with pathology.Glucocorticoid is an effective treatment.
