Objective:To investigate the number and distribution of macrophages (Mφ) and natural killer(NK) cells in hepatocellular carcinoma (HCC), paraneoplastic,cirrhosis and normal liver tissues and their relationship with the prognosis of HCC patients.　Methods:Surgical specimens from 60 cases of HCC, 62 cases of cirrhosis and 23 cases of normal liver tissues were investigated by immunohistochemical staining of CD68 and CD57 with a streptavidin-horseradish peroxidase detective system.The correlation of the number of Mφ and NK cells in different tissues with the clinical tumor parameters was also studied.　Results:①The order of the number of Mφ from the highest to the lowest was:paraneoplastic,cirrhosis, normal, HCC(P<0.05)；and the number of NK cells from the highest to the lowest was:HCC, paraneoplastic, normal, cirrhosis(P<0.05).②The number of Mφ decreased successively with the decrease of the HCC differentiation(P<0.05)；There was no relationship between the number of NK cells in HCC and histological grade. ③There was no relationship between the number of Mφ in HCC and clinical TNM stage ；The number of NK cells in HCC had degressive tendency with the clinical TNM stage(P<0.05). ④The number of Mφ and NK cells in HCC in the cases with metastasis in 15 months was significantly lower than that without metastasis(P<0.05, 0.01）.⑤There was a linear positive correlation between the number of Mφ and NK cells in HCC (r＝0.344, P<0.05).　Conclusion:The number of Mφ and NK cells in HCC in the cases with metastasis is significantly lower than that without metastasis；The number of Mφ has a close correlation with the HCC differentiation, and positive correlation with the number of NK cells；The number of Mφ and NK cells might be important markers to estimate the immune status and useful factors to predict the prognosis of HCC patients.

Objective To study the effect of continuing flushing with heparin on the prevention of tube obstruction after vacuum sealing drainage(VSD).Methods Seventy-four patients with large area of skin defects treated by VSD were randomly divided into experiment group and control group. The experiment group were managed by continuous infusion with saline at 250 mL and heparin at 12500 U (50 U/mL)in 24 h after operation,with 20 to 30 drops per minute and two times a day. The control group included 33 cases was injected with 20 mL saline when the drainage tube blocked until the VSD tube was unobstructed. The two groups were compared in terms of drainage time, drainage tube,wound healing time,rate of un-obstruction of tubes and histopathological scores.Results The drainage time and wound healing time of experiment group were significantly shorter than that of control group(P<0.05). The rate of un-obstruction of tubes was higher than the control group and so it was with the score in histopathology.Conclusion Continuous flushing with heparin can effectively reduce the incidence of VSD obstruction and promote wound healing.

Objective To investigate the correlation between the expression of peripheral blood CD8 + T lymphocytes and the severity degree of hand,foot and mouth disease( HFMD)in children infected by enterovirus( EV)71 at different ages,and further to predict the role of the expression of CD8+ T lympho-cytes played in the occurrence of neurological complications infected by EV71. Methods A total of 138 pe-ripheral blood samples derived from the confirmed HFMD cases were collected in the department of infectious disease at Kunming Children′s Hospital between March and September in 2014,including 33 mild cases,45 severe cases,and 60 critical cases. Patient ages were 9 months to 5 years old. Flow cytometry was used to detect the expression of peripheral blood CD8 + T lymphocytes in all of above patients. Results Compared to the reference value of CD8 + T lymphocytes in normal healthy children at different age groups,the percentage of peripheral blood CD8 + T lymphocytes elevated or increased slightly in patients of all ages,except the obvi-ously increasing expression in the age group of ~2 years and decreasing expression in critical cases of the age group of ~5 years. The expression of peripheral blood CD8+ T lymphocytes significantly increased in mild and severe patients but slightly increased in critical patients of the age group of 9 to 15 months,gradually de-creased in the age group of ~2 years and slightly increased in mild and severe cases but decreased in critical patients of the age group of ~5 years. There were significant differences between the patients in mild condi-tion and in severe condition or critical condition respectively within the age group of ~2 years( P﹤0. 05 ), and there were no significant differences in other age groups between different severity of disease. Conclusion
There are correlations between the expression of CD8+ T cells and the severity of HFMD in patients at different ages. Especially,the patient′s condition developing into severe degree is associated with the rapid decreasing of CD8 + T cells in HFMD patients of the age group of ~2 years. CD8+T cells play an important role in antiviral immune response in HFMD patients of ~2 years old.

Objective To investigate the impact of sputum suction under laryngoscope in stroke patients on the occurrence and prognosis of ischemic stroke-associated pneumonia (SAP).Methods A total of 127 cases with acute ischemic stroke (AIS) with Glasgow Coma Scale 6-12 scores,non-artificial airway and need for intensive care were enrolled.According to the suction practice,the cases were divided into laryngoscope euthyphoria group (practice group,PG,n =59),and conventional oral or nasal sputum suction group (control group,CG,n =68).The PG was perspectively studied,while the CG were analyzed retrospectively.All patients were cared with the Guidelines for the management of adult with hospitalacquired ventilator-associated and healthcare-associated pneumonia set by American Thoracic Society/Infectious Diseases Society of America in 2005 and the Guidelines for the early management of patients with acute ischemic stroke set by American Heart Association/American Stroke Association in 2013 including patting on the back of patients in prone position routinely in order to facilitating expectoration,phlegm elimination with physical vibration and apophlegmatic agent application during their stay in ICU.Incidences of SAP and 28-day mortality were calculated.Levels of inflammatory markers (white blood cell,WBC;highsensitive C-reaction protein;procalcitonin,PCT) in serum were detected.Adverse events related to laryngoscopy were documented.Results There were no significant differences in incidences of SAP and 28-day mortality between PG and CG groups (32.20％ vs.41.18％,P ＞ 0.05;47.37％ vs.53.57,P ＞ 0.05,respectively).However,there was statistically significant difference (P ＜ 0.05) in the ICU stay length and inflammatory markers,and the sputum suction process in PG did decrease the incidence of artificial airway establishment and mechanical ventilation (18.64％ vs.35.29％,P ＜ 0.05),and the laryngoscope euthyphoria method was proved to be a protective factor (HR =0.515;95％ CI 0.281-0.057,P =0.038).WBC and PCT were lower in PG group than in CG group (P ＜ 0.05).Conclusion Sputum suction under laryngoscope can reduce the probability of artificial airway establishment and invasive ventilator employment in patients with AIS,shortening ICU stay length and down-regulating levels of WBC and PCT.

Objective To investigate the effect of 4-phenylbutyric acid(4-PBA)on the renal pathogenesis of rats with streptozotocin-induced diabetes and its mechanism. Methods Fifty-four male SD rats were randomly divided into three groups:normal control group(NC group,n=18),diabetic nephropathy group(DN group,n=18),diabetic nephropathy plus 4-PBA treatment group(4-PBA group,n=18).At the end of 4,8 and 12 weeks,index of kidney weight/body weight ratio(KI)were measured and calculated.Serum creatinine (Scr),blood urea nitrogen(BUN),urinary MDA levels,urinary SOD activity,and 24 hour urinary protein excretion ram(UAER)were detected by HITACHI automatically.Morphology of kidney wag examined by special staining of periodic acid-schitt (PAS).The p47phox and nitrotyrosine (NT) expression in kidney were determined by real-time fluorescence PCR and Western blotting. Results Compared with the NC group, the DN group rats showed a significant increase of KI(P＜0.05), UAER(mg/24 h) (4.92±0.70 vs 0.26±0.07, 5.29±0.83 vs 0.28±0.08, 5.54±0.81 vs 0.29±0.04,respectively, P＜0.05]for indicated time, mesangial cells proliferation and mesangial matrix expansion at 12 week. However,4-PBA treatment could significantly inhibit the increase of KI (P＜0.05), decrease UAER (mg/24 h) (3.71±0.37, 3.47±0.36, 3.28±0.40, respectively, P＜0.05]for indicated time, and prevent the glomeruler pathological alteration induced by diabetes. Moreover, the mRNA expression of p47phox in the kidney of DN group was 154.72%, 148.60% and 91.95% more than that of NC group (all P＜0.05) for indicated time. The protein expression of p47phox was 118.00%, 140.10% and 177.82% more than that of NC group (all P＜0.05), and the protein expression of NT was 45.29%,59.13% and 89.28% more than that of NC group (all P＜0.05). In addition, urinary MDA levels in DN group were 2.05-, 2.26- and 2.43- folds of NC group, and urinary SOD activities were decreased by 64.78%, 71.29% and 79.32% of NC group. Compared with the DN group, the mRNA and protein expression of p47phox, and protein expression of NT in 4-PBA group were decreased markedly (all P＜0.05) at the end of 8 and 12 weeks. The urinary MDA level was decreased, and the urinary SOD activity was increased significantly in rats with diabetes after 4-PBA treatment for indicated time (all P＜0.05). Conclusion 4-PBA treatment can significantly inhibit the renal pathogenesis of rats with diabetes through inhibition of oxidative stress.
