ObjectiveTo identify the correlation factors for urosepsis shock after endourology surgery and analyze its clinical characteristics.MethodsFifty-eight patients with urosepsis without shock and 15 patients with shock were studied.Factors which may be correlated with the development of sepsis were analyzed including age,sex,ASA physical status,history of urinary tract infection,preoperative leukocyturia,urine bacteria culture,prophylactic antimicrobial treatment,pyonephrosis,type of surgery,duration of operation,blood leukocyte count and concentration of creactive protein at the end of surgery,the time when the signs of infection (shivering,agitation,nausea or vomiting) first appeared.Changes in BP in patients with urosepsis shock,scores for multiple organ dysfunction syndrome as well as treatment and prognosis were also recorded.ResultsFemale sex and early emergence of signs of infection after surgery were correlated with urosepsis shock.Abrupt hypotension was usually the first manifestation of urosepsis shook.The lowest systolic BP was positively correlated with the time when diagnosis of shock was made and negatively correlated with the length of ICU stay and the highest multiple organ dysfunction syndrome scores but not correlated with shock correction time.All patients with urosepsis shock recovered completely when discharged from hospital.ConclusionFemale sex and patients with early emergence of signs of infection are prone to develop urosepsis shock after endourology operation.The prognosis of urosepsis shock is good if diagnosed and treated in time.

OBJECTIVETo compare agitated saline solution (AS) and the mixture of AS with blood (ASb) as the contrast agents in contrast transcranial Doppler (c-TCD) in the diagnosis of patent foramen ovale (PFO).

METHODSWe recruited 248 consecutive patients for c-TCD examination between November 2015 and January 2016, and the sequence of the use of AS (9 mL saline solution mixed with 1 mL air) and ASb (9 mL saline solution and a drop of the patient's blood mixed with 1 mL air) was determined by coin-tossing method. Before the examination, the contrast agent was injected with or without Valsalva maneuvers (VM), and the number of microbubbles within 25 s after the contrast agent injection and the time of first appearance of microbubbles were recorded by observing the TCD spectrum. Each injection was repeated twice and the interval between tests was at least 5 min. We classified PFO according to the number of microbubbles into negative (no microbubble), grade I (1-10 microbubbles), grade II (>10 microbubbles but no curtain), and grade III (with curtain).

RESULTSs The positivity rates in diagnosis with AS without VM, AS with VM, ASb without VM, and ASb with VM tests were 10.9%, 23.8%, 12.1% and 25.8%, respectively. AS with VM test had a higher positive rate than AS without VM test (23.8% vs 10.9%, P=0.001), and ASb with VM test had a higher positive rate than ASb without VM test (25.8% vs 12.1%, P=0.001). The positive rates were similar between ASb without VM and AS without VM test (12.1% vs 10.9%, P=0.250) and between ASb with VM test and AS with VM test (25.8% vs 23.8%, P=0.125).

CONCLUSIONVM can improve the positive rate of PFO diagnosis in c-TCD examination, and the positive rates are comparable between examinations using the contrast agents AS and ASb.

Objective To optimize the method for radiotherapy target delineation after breast cancer surgery, and to observe its advantage in raising work efficiency. Methods Ten physicians in our department were selected, and 20 patients who received breast?conserving surgery were randomly selected. The 10 physicians delineated the targets for these patients with the method in the control group and the method in the study group, and the time required for each delineation was recorded. The method in the control group was commonly used in daily practice and the method in the study group was optimized. The independent?samples t test was applied to compare the differences between the two groups. Results With the optimized method, the average time of delineation in the study group was less than that in the control group ( 51 min vs. 65 min, P=0. 029) . The time curves for delineation in the control group were relatively flat;the time curves for delineation in the study group were high at first, then decreased gradually, and finally became flat. The time for each physician to finish delineation skillfully was relatively stable, while in the study group, the time started to decrease after delineation for the first few patients, with an apparent learning process. Conclusions The optimized method for target delineation in breast cancer is feasible, reliable, and easy to master, and can increase work efficiency, which is more obvious in physicians with rich experience in delineation.

Pancreatic ductal adenocarcinoma (PDAC) is among the most devastating human malignancies. The poor clinical outcome in PDAC is partly attributed to a growth-permissive tumor microenvironment. In the PDAC microenvironment, the stroma is characterized by the development of extensive fibrosis, with stromal components outnumbering pancreatic cancer cells. Each of the components within the stroma has a distinct role in conferring chemoresistance to PDAC, and intrinsic chemoresistance has further worsened this pessimistic prognosis. The nucleoside analog gemcitabine (GEM) is usually the recommended first-line chemotherapeutic agent for PDAC patients and is given alone or in combination with other agents. The mechanisms of intrinsic resistance to GEM are an active area of ongoing research. This review highlights the important role the complex structure of stroma in PDAC plays in the intrinsic resistance to GEM and discusses whether antistroma therapy improves the efficacy of GEM. The addition of antistroma therapy combined with GEM is expected to be a novel therapeutic strategy with significant survival benefits for PDAC patients.

OBJECTIVETo determine the correlation of the CYP1A1 (rs4646422) gene polymorphisms with male infertility in the Chinese Han population.

METHODSUsing the Mass ARRAY iPLEX GOLD technique, we conducted a case-control study on theCYPlA1 (rs4646422) gene polymorphisms in 636 infertile males aged 21-49 years (case group) and 442 normal healthy men aged 23-47 years (control group) of the Chinese Han population. We analyzed the genotypes and allele frequencies in the two groups ofsubjects with the SPSS 20.0 software.

RESULTSCompared with the wild homozygous genotype GG, the heterozygous genotype AG (OR = 1.06, 95% CI 0.81-1.38) and homozygous genotype AA (OR = 1.11, 95% CI 0.56-2.21) showed no correlation with male infertility, nor did the mutant allele A (OR = 1.06, 95% CI 0.85-1.32) in comparison with the wild allele G.

CONCLUSIONThe CYP1A1 (rs4646422) gene polymorphisms might not be correlated with male infertility in the Chinese Han population.

Objective To analyze changes and trends of the mortality and causes of death in the residents of Minhang District of Shanghai from 1996 to 2015.Methods Crude death rates (CDR) and age-standardized death rates (ADR) were calculated,respectively.Joinpoint regression was used to analyze the trends in the leading causes of death.Permutation test was used to find whether the joinpoints were statistically significant based on P value＜0.05.Results The elderly population in Minhang District accounted for 18.07％ of the total population in 2015,which increased by 73.89％ than it in 1996.The CDRs of all causes for resent 20 years gradually increased with the annual percentage change (APC) of 0.62％ (P＜0.05),but decreased significantly after standardization (APC =-3.73％,P＜0.05).In 2015,the top five causes of death were circulatory disease;neoplasms;respiratory disease;endocrine,nutritional and metabolic diseases;injury and poisoning in the total population,males and females registered in Minhang District.ADRs of circulatory disease,neoplasms,respiratory disease and injury and poisoning decreased to-3.16％,-1.86％,-8.03％ and -4.96 ％,respectively (P＜0.05).ADRs of endocrine,nutritional and metabolic diseases significantly increased during 1996 to 2001 (APC=16.58％,P＜0.05) and thereafter remained stable.Conclusions The issue of population aging in Minhang District is getting worse,and chronic non-communicable diseases and injury and poisoning can be identified as major public health concerns at present.

OBJECTIVETo observe the effects of interleukin-8 monoclonal antibody on smooth muscle cell proliferation and balloon inflation-induced abdominal aorta stenosis in rabbits.

METHODSThirty-six New Zealand white rabbits were randomly assigned to balloon inflation group (group A, n = 12), interleukin-8 monoclonal antibody pre-treated rabbits (2 mg/kg for 3 days before balloon inflation, group B, n = 12) and sham-operated control group (group C, n = 12). Peripheral blood was collected before experiment and at 4 h, 1, 3, 7, 14, and 28 days post balloon inflation or sham operation and the levels of IL-8 were measured by enzyme linked immunosorbent assay (ELISA). The ratio of positive and negative masculine cells in the high power microscopic field was determined in proliferating cell nuclear antigen (PCNA) stained slide. Histopathologic examination was performed in abdominal aorta and luminal area, intima and tunica media area were measured.

RESULTSPlasma interleukin-8 began to rise at 4 h and peaked at 1 day and remained increased up to 28 days after balloon inflation in rabbits of group A, plasma interleukin-8 level in group A was significantly higher than in group B and C at 4 h and thereafter post operation. The ratio of positive and negative masculine cells was significantly increased in group A compared to group C and was significantly lower in group B than in group A. Abdominal aorta stenosis, luminal area, intima and tunica media area were significantly reduced in group B than in group A. Correlation analysis indicated that there were positive relations between plasma IL-8 level and intima thickness, area of intima and tunica media, respectively (r = 0.894, 0.783, 0.801, 0.912, all P < 0.01).

CONCLUSIONSPlasma IL-8 level is increased in this abdominal aorta stenosis model and is positively correlated to the severity of abdominal aorta stenosis. IL-8 monoclonal antibody could significantly reduce abdominal aorta stenosis in this abdominal aorta stenosis model.

Objective:To evaluate the long-term efficacy of endoscopic transluminal drainage(ETD) for acute pancreatitis complicated with walled-off necrosis (WON) or pancreatic pseudocyst (PPC).Methods:A total of 79 patients who were diagnosed as having WON or PPC by abdominal CT or ultrasound and treated with ETD in Nanjing Drum Tower Hospital were enrolled. Past medical records and follow-up by phone call after discharge were analyzed for long-term outcomes including endocrine and exocrine functions and long-term quality of life.Results:A total of 50 patients were enrolled, including 31 patients with infected WON/PPC and 19 patients with uninfected WON/PPC. Seventeen patients (54.84%) in the infected WON/PPC group and 11 patients (57.89%) in the uninfected WON/PPC group lost 5% or more of their weight. There were no significant differences in the proportion of cases of weight loss of 5% or more ( P=0.833), or the weight loss between the two groups (12.59±8.89 kg VS 10.91±2.47 kg, P=0.522). Only one patient in the infected WON/PPC group had chronic abdominal pain. There was no significant difference in the Izbicki score between the two groups (23.79±6.74 VS 22.03±3.21, P=0.295). None of the patients developed steatorrhea after discharge. Five patients (16.67%, 5/30) in the infected WON/PPC group and 6 patients (40.00%, 6/15) in the uninfected WON/PPC group developed endocrine insufficiency with no significant difference ( P=0.140). Greater risk of secondary diabetes resulted from higher low-density lipoprotein cholesterol ( HR=1.9, 95% CI: 1.0-3.4, P=0.044)and triglycerides ( HR=1.2, 95% CI: 1.0-1.3, P =0.029). Conclusion:ETD is safe and effective for WON and PPC. But there is possibility that patients develop secondary diabetes. Additionally, greater risk of secondary diabetes results from higher low-density lipoprotein cholesterol and triglycerides.

OBJECTIVEWe observed the therapeutic effectiveness and safety of different antidepressants as well as the correlation between symptomatic improvement of depression and improvement of chest pain in patients with susceptible "angina pectoris" and negative coronary angiogram complicating comorbid depression.

METHODSIn this double-blinded randomized study, a total of 123 eligible patients were allocated into three groups: (1) Group F: fluoxetine 20 mg QN (n = 41); (2) Group P: Placebo 1 tablet QN (n = 40); (3) Group F + O: fluoxetine 20 mg + olanzapine 2.5 mg QN for the former 2 weeks and only fluoxetine 20 mg QN for the latter 2 weeks (n = 42). The total therapy duration was 4 weeks. HAMD, HAMA and self-evaluation table of chest pain were obtained before therapy, at the end of 1 and 2 weeks after therapy.

RESULTSBaseline HAMD and HAMA scores and self-evaluation score of chest pain were similar among 3 groups and all scores were significantly improved post various therapies in the order of group F + O > group F > group P. The rate of score decrease were seen after 1 week treatment in group F + O and after 2 week treatment in group F. There was a significant positive correlation between the rates of self-evaluation chest pain score decrease and HAMD (r = 0.867, P < 0.001) and HAMA (r = 0.854, P < 0.001) score decreases after 4 weeks therapies (P < 0.05). During the whole course of treatment, no serious adverse reaction was found in all patients.

CONCLUSIONIn patients with suspected "angina pectoris" and negative coronary angiogram complicating comorbid depression, the antidepressants were safe and significantly improved the symptoms of depression and anxiety and chest pain. Low dose fluoxetine plus short term olanzapine regimen was superior to fluoxetine alone regimen in terms of stronger and quicker symptom improvement.

Objective To investigate the effect of microRNA-9-5p (miR-9-5p) regulating transient receptor potential melastatin 7 (TRPM7) on myocardial ischemia-reperfusion (MIR) in rats. Methods Thirty-two SD rats were divided into sham operation group, model group, miR-9-5p overexpression group and empty vector control group. The MIR model was established by ligation of left coronary artery. The sham operation group was not ligated. miR-9-5p agomir and agomir NC were injected into tail vein 24 hours before model establishment in miR-9-5p overexpression group and empty vector control group. The myocardial injury was observed by HE staining. The expression of miR-9-5p was detected by Real-time PCR. The serum levels of interleukin(IL)-6, tumor necrosis factor alpha(TNF-α), IL-1β, creatine kinase isoenzyme MB (CK-MB), cardiac troponin Ⅰ (cTnI), lactate dehydrogenase (LDH) and the contents of malondialdehyde (MDA) and superoxide dismutase (SOD) in myocardium were measured were measured by ELISA. Cardiomyocyte apoptosis was detected by TUNEL. Double luciferase assay verified the relationship between miR-9-5p and TRPM7. The protein expressions of TRPM7, Bcl-2, Bcl-2 associated X (Bax), phosphorylated nuclear factor kappa-B 65 (p-NF-κB p65) and toll like receptor 4 (TLR4) were detected by Western blotting. Results The expression of miR-9-5p was low in myocardial tissue of rats (P<0.05). Overexpression of miR-9-5p could reduce the expression levels of CK-MB, cTnI and LDH, and improve the degree of myocardial injury. Compared with the model group, the apoptosis rate, Bax protein expression, MDA, IL-6, TNF-α and IL-1β contents in myocardial cells of miR-9-5p overexpression group decreased, while Bcl-2 protein expression and SOD content increased (P<0.05). The result of dual luciferase assay showed that TRPM7 was the target gene of miR-9-5p, and the protein expressions of TRPM7, p-NF-κB p65 and TLR4 in miR-9-5p overexpression group were lower than those in model group (P<0.05). Conclusion MiR-9-5p can inhibit myocardial cell apoptosis, oxidative stress and inflammation induced by myocardial ischemia-reperfusion, and inhibit TLR4/NF-κB pathway by regulating TRPM7.
