Academic Journal of Second Military Medical University 2014;35(6):676-680
Objective: To assess, the safety and early oncologic results of minimally invasive esophagectomy (MIE) combined with super-extended two-field lymph node dissection for treating esophageal squamous cell carcinoma. Methods A total of 49 patients who underwent MIE through McKeown approach (right chest, left neck, and abdomen) between May 2012 and Dec. 2013 were enrolled in this study. Lymph node dissection fields included whole mediastinum, lower para-esophagus via thoracoscope route, and abdomen. Results: The patients included 44 males and 5 females, with an age range of 45-78 years old and a median of 58 years old. Sixteen (32. 7%) patients were at Stage I. Forty-eight (98. 0%) patients received complete resection, and 18 (36. 7%) patients had post-operation complications, including 9(18. 4%) with neck leakage and 7 (14. 3%) with vocal cord paralysis. Post-operative early death occurred in one case. The mean number of removed lymph nodes was 18 and the lymph node metastasis rate was 42. 9% (21/49); 28. 6% (6/21) of the positive nodes were found in the upper mediastinum and lower para-esophagus areas. Seven of the 18 patients who were followed up had recurrence, with a recurrent rate of 38. 9%. The 7 cases included 5 in the locoregional areas and 2 in distant organs. Conclusion: MIE combined with super two-field dissection can achieve the lymphadenectomy effect recommended by National Comprehensive Cancer Network (NCCN), with satisfactory safety. Short-term follow-up indicates that the locoregional recurrence is more frequent than distant metastases, demanding more thorough mediastinal lymph node dissection.

OBJECTIVETo compare the safety and efficacy of RevoLix 120 W 2 µm continuous-wave (cw) laser enucleation of the prostate with transurethral resection of prostate (TURP) in patients with symptomatic benign prostatic hyperplasia (BPH). And to evaluate clinical value of 120 W 2 µm cw laser enucleation.
METHODSAll 168 patients with BPH underwent 2 µm cw laser enucleation (n = 88) or TURP (n = 80) between January 2010 and January 2011. The operative time, drop in hemoglobin, drop in serum sodium, indwelling catheterization time and operative complications were recorded. International prostate symptom score (IPSS), quality of life (QOL), urinary peak flow rate (Qmax) and post-voiding residual urine (PVR) were also compared.
RESULTSThe mean operative time was slightly longer in the 2 µm laser group ((63.2 ± 21.6) min) than the TURP group ((59.4 ± 18.6) min) (P > 0.05). Transfusions were not necessary in 2 µm laser group. Catheter indwelling time were (1.8 ± 0.6) days vs. (3.5 ± 2.6) days in 2 µm laser group than in TURP group (t = 3.912, P < 0.05). All cases were followed up for 3 - 12 months, the IPSS, QOL, Qmax and PVR were 6.1 ± 2.0, 4.4 ± 1.6, (18.8 ± 4.8) ml/s and (21.6 ± 16.5) ml in the 2 µm laser group, and were 6.3 ± 2.4, 1.9 ± 1.1, (18.4 ± 4.2) ml/s, (23.2 ± 14.6) ml in TURP group respectively. All the markers were improved significantly compared with that of preoperative in both groups (t = 12.453 - 26.213, P < 0.01), but no statistical differences could be found between the two groups. Perioperative complications were less in the 2 µm laser group.
CONCLUSIONSThe 120 W 2 µm cw laser enucleation is an novel excellent treatment for BPH as well as TURP, and has the advantage of significantly less blood loss, shorter hospitalization, shorter catheter indwelling time and rapid recovery after surgery.

OBJECTIVETo evaluate the optimal timing of hepatectomy for intrahepatic lithiasis complicated with acute cholangitis.
METHODSOne hundred and twenty-six patients with hepatolithiasis who had a history of acute cholangitis and underwent hepatectomy were reviewed retrospectively. According to the period between the surgery and last attack of acute cholangitis, 126 patients were divided into 3 groups: > 3 months (group A, n = 73), 1 approximately 3 months (group B, n = 28), < 1 month (group C, n = 25). The operation time, blood loss, hospital stay, postoperative complications and stone residual rate were compared among the groups.
RESULTSThe intraoperative blood loss of C group was (644.0 +/- 625.7) ml, which was significantly higher than those of A and B group [(409.2 +/- 250.7) ml and (423.2 +/- 237.1) ml, respectively]. The numbers of patients who needed transfusion and the amount of blood transfusion in group C were also higher than those of group A and B. The incidence rate of complications, residual stone in group C were all markedly higher than those of group A and B. The period of hospital stay in group C was much longer than that in group A and B.
CONCLUSIONSThe optimal timing of hepatectomy for hepatolithiasis complicated with acute cholangitis is at least one month after subsidence of cholangitis.

OBJECTIVETo evaluate the preliminary clinical outcomes of coccygectomy in patients with coccydynia after a failure of conservative treatment.
METHODSFrom May 2002 to January 2010, 31 patients with coccydynia were treated by coccygectomy in our department after conservative measures had failed to produce significant relief. A questionnaire, which included the extent of relief in the painful area, improvement in quality of life, intensity of pain in the sitting position, and pain score during daily activities, was used to evaluate the results.
RESULTSAll patients were followed up for 1 to 6 years (mean 3.3 years). The results were excellent in 20 patients (64.5%), good in 7 patients (22.6%), moderate in 3 patients (9.7%) and poor in 1 patient (3.2%). The excellent and good rates amounted to 87.1%. All patients except one had complete resolution of their symptoms and were subjectively highly satisfied with the outcomes of the surgery. Only 2 cases of superficial infection were observed postoperatively.
CONCLUSIONCoccygectomy is a feasible management option for patients with coccygodynia that has no response to conservative treatments.

OBJECTIVETo study the indoor environmental factors associated with the prevalence of asthma and related allergies among school children.
METHODSA cluster sampling method was used and the ISAAC questionnaire was conducted. A total of 4612 elementary students under Grade Five of 7 schools were enrolled in the survey for the impact of indoor environmental factors on the prevalence of asthma and related allergies in several urban and suburban schools of Beijing.
RESULTSA total of 4060 sample were finally analyzed including 1992 urban and 2068 suburban. The prevalence of wheeze, allergic rhinoconjunctivitis and atopic eczema in the past 12 months was 3.1% (61/1992), 5.3% (106/1992), 1.1% (22/1992) among urban children while 1.3% (27/2068), 3.1% (65/2068), 1.0% (22/2068) among suburban children respectively. The prevalence of wheeze and allergic rhinoconjunctivitis of the past 12 months in urban were both significantly higher than that in suburban (χ(2) = 14.77, 11.93, P < 0.01). The incidences of having asthma and eczema ever among urban children (5.3% (105/1992), 29.4% (586/1992)) were significantly (χ(2) = 39.03, 147.22, P < 0.01) higher than that among suburban (1.7% (35/2068), 13.8% (285/2068)). Although the distributions of indoor environmental factors were similar in both areas, passive smoking and interior decoration had different influence on the prevalence of asthma and related allergies among school children in the two areas. The significant impact of passive smoking on having asthma ever among suburban children was observed (OR = 2.70, 95%CI = 1.17 - 6.23) while no significant result in urban (OR = 1.06, 95%CI = 0.71 - 1.58); the percentage of interior decoration was 84.0% (1673/1992) among urban children and 80.0% (1655/2068) among suburban children, there was significant impact of interior decoration on the prevalence of having eczema ever among urban children (OR = 1.57, 95%CI = 1.17 - 2.10) but no significant results were found in suburban sample (OR = 1.06, 95%CI = 0.76 - 1.48).
CONCLUSIONThe prevalence of asthma and related allergies among school children is much higher in urban areas than that in suburban areas and the indoor environmental factors such as passive smoking and interior decoration may differently explain the prevalence of asthma and related allergies in the two areas.

To investigate the induction method and function of dendritic cells (DC) derived from acute myelogenous leukemia (AML) blasts in vitro, cytokine-supplemented suspension cultures of leukemia blasts in 25 AML patients were performed. Mononuclear cells were cultured for 8 to 12 days using recombinant human granulocyte-macrophage colony stimulating factor (rhGM-CSF), recombinant human interleukin-4 (rhIL-4) and recombinant human tumor necrosis factor-alpha (rhTNF-alpha). Morphology, phenotype, cytogenetics, and function of induced cells were studied. The results showed that after culture for 3 days, cells in 20/25 AML cases demonstrated an increase in size with dendritic morphology. After culture for 8 - 9 days, the percentage of such cells reached peak. When cultured for 12 days, the total number of cells and the number of cells with DC morphology decreased greatly. Phenotypic analyses of cells (11/20 cases) were measured by flow cytometry before and after culture. Before culture, cells did not express CD1a, CD80 and CD83, while expressed CD54, CD86 and HLA-DR with low frequency. After culture, cells upregulated CD1a, CD80, CD83, CD54, CD86 and HLA-DR significantly. A marked increase of the T-cell stimulatory capacity could be generated in Allo-MLRs. FISH confirmed the leukemic origin of generated cells. In conclusion, leukemia-derived DC can be generated from AML blasts using cytokine combination (GM-CSF, IL-4, and TNF-alpha) in vitro.

BACKGROUNDC-reactive protein (CRP) is a lowly expressed marker for inflammatory response. This study aimed to evaluate the prognostic value of baseline CRP levels in patients undergoing coronary revascularization in the context of modern medical treatment.
METHODSThis was a retrospective study in a single center. Four hundred and fourteen patients were enrolled, who underwent coronary revascularization and received adequate medication for secondary prevention of coronary heart disease. The study compared the follow-up clinical outcomes between high level CRP group (CRP > 5 mg/L) and low level one. The median follow-up time was 551 days.
RESULTSCompared with low CRP group, the relative risk (RR) of the major adverse cardiovascular and cerebral events (MACCE) in high CRP group was 5.131 (95%CI: 1.864-14.123, P = 0.002). There were no significant differences in death, myocardial infarction and stroke during the follow-up between two groups, but a higher risk of re-revascularization was found in high CRP group (RR 6.008, 95%CI: 1.667-21.665, P = 0.006). Cox regression analysis showed that only CRP level could contribute to MACCE during the follow-up. MACCE-free rate was much lower in high CRP group (Kaplan-Meier log-rank P < 0.001).
CONCLUSIONIn the context of modern medical treatment, the baseline level of CRP is an independent predictor for long-term prognosis in patients with coronary revascularization.

BACKGROUNDThe optimal revascularization strategy in patients with heart failure with preserved ejection fraction (HFPEF) remains unclear. The aim of the present study was to compare the effects of percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in patients with HFPEF.
METHODSFrom July 2003 through September 2005, a total of 920 patients with coronary artery disease (CAD) and HFPEF (ejection fraction ≥ 50%) underwent PCI (n = 350) or CABG (n = 570). We compared the groups with respect to the primary outcome of mortality, and the secondary outcomes of main adverse cardiac and cerebral vascular events (MACCE), including death, myocardial infarction, stroke and repeat revascularization, at a median follow-up of 543 days.
RESULTSIn-hospital mortality was significantly lower in the PCI group than in the CABG group (0.3% vs. 2.5%, adjusted P = 0.016). During follow-up, there was no significant difference in the two groups with regard to mortality rates (2.3% vs. 3.5%, adjusted P = 0.423). Patients receiving PCI had higher MACCE rates as compared with patients receiving CABG (13.4% vs. 4.0%, adjusted P < 0.001), mainly due to higher rate of repeat revascularization (adjusted P < 0.001). Independent predictors of mortality were age, New York Heart Association (NYHA) class and chronic total occlusion.
CONCLUSIONAmong patients with CAD and HFPEF, PCI was shown to be as good as CABG with respect to the mortality rate, although there was a higher rate of repeat revascularization in patients undergoing PCI.

OBJECTIVETo evaluate the risk factors related to mortality in old patients with coronary heart disease after revascularization.
METHODSA total of 675 patients (498 males) with age >or= 70 years old who received revascularization during July 2003 to June 2004 and followed up > 30 days after discharge were included in this study. Clinical characteristics, death and major adverse cardiac and cerebral events (MACCE) during follow up were recorded.
RESULTSThe patients were followed up for a mean period of (754 +/- 355) days. 27 patients (4.0%) died and MACCE developed in 50 patients (7.4%) during follow up. Female and patients with anemia took a significantly higher risk of mortality (RR = 2.750, 95% CI 1.116 - 6.779, P = 0.028, RR = 0.385 95% CI 0.164 - 0.904, P = 0.028, respectively); Creatinine level is positively related to mortality rate. When comparing patients with Cr > 115 micromol/L and Cr > 177 micromol/L with patients with Cr < 115 micromol/L, the hazard rate was 2.963 and 10.785, respectively (95% CI 1.114 - 9.952, P = 0.035 and 95% CI 2.659 - 78.097, P = 0.000) after adjustment for other risk factors.
CONCLUSIONPreexisting anaemia (male Hb < 120 g/L, female Hb < 110 g/L), renal insufficiency (Cr > 115 micromol/L) and female gender were found to be independent risk factors for mortality in old patients with coronary heart disease post revascularization.
