The expression of proliferating cell nuclear antigen (PCNA) was studied in 50 cases of squamous cell carcinoma of the skin using immunohistochemistry and PCNA cyclin monoclonal antibody. PCNA staining was found in the nuclei of tumour cells, two types of staining were seen, a granular pattern and a more diffuse nuclear staining. The expression of PCNA showed a significant positive correlation with degrees of differentiation of the carcinoma cells and lymph node metastasis (P

The expressions of p53 protein, PCNA and macrophage count in 50 cases of skin squamous cell carcinoma were studied by LSAB immunostaining of monoclonal antibodies (PC-10, CD68 and Do-7). The relationship between the proliferation of cancer cell and the count of stroma macrophage to the degree of differentiation was studied and observed in situ. The results showed that the positive rates of expression of both p53 protein and PCNA in the squamous cell carcinoma were 56% and 100%, respectively. The distribution and strength of the expression of p53 protein and PCNA were positively correlated to the degree of cell differentiation. Macrophoge regularly located in the margin of cancer nest. The macrophage count was reversely correlated to the degree of differentiation. It is concluded that the degree of differentiation is parallel to the expression of p53 protein and PCNA, whereas, the macrophages in the stroma to some extent inhibits the cancer cell proliferation.

Objective To evaluate the effects of desamethasone in pregnancy on fetal pituitary-adrenal functions.Methods From May 2003 to November 2003 24 cases of intrahepatic cholestasis of pregancy(ICP) in the third trimester were treated with dexamethasone.The levels of ACTH and cortisone in the umbilical blood were detected after delivery.The pregnant Wistar rats were intramuscularly injected of dexamethasone(1 mg?kg-1?d-1) from the pregnancy day 15 for 5 days as group B,while the rats in group A received no dexamethasone as control group.The levels of ACTH and cortisone of the rat fetus as well as the ACTH in fetal pituitary gland by immunohistochemistry were examined.Results The ACTH level in the umbilical blood of the fetus increased and the cortisone level decreased as compared to that of the control group.Treatment with desamethasone to pregnant rats resulted in enhanced expression of ACTH,increased serum ACTH concentration,and decreased concentration of cortisol in the rat fetal pituitary gland.Conclusion Treatment with dexamethasone in pregnancy causes some impact on the adrenal gland of the newborn rats in the near future.

OBJECTIVE:To provide reference for clinical rational drug use.METHODS:The content of Levocarnitine Injection from two manufactories in 3 different dissolvants(5%Glucose,0.9%Sodium Chloride Injection,and Fructose Injection) within 6 h was determined by HPLC.The change of microparticle was measured by light blockage method in accordance with China Pharmacopeia(2005 edition),and the appearance and pH of the mixtures were observed as well.RESULTS: The changes in appearance,turbidance,pH value,content and microparticle were not significant.CONCLUSION: Levocarnitine Injections from two manufactories were stable within 6 h after mixing with 3 different dissolvants(5%Glucose, 0.9%Sodium Chloride Injection,and Fructose Injection).

Objective To investigate the immune protective effect of recombinant growth hormone on chronic obstructive pulmonary disease ( COPD) patients with typeⅡin respiratory failure during the application of ventilator.Methods 52 patients with COPD with respiratory failure in Taizhou City Hospital from July 2014 to November 2015 in this study who were treated with ventilator therapy were divided into two groups.The control group received routine treatment, and the treatment group received more with recombinant growth hormone 8 U/d subcutaneous injected.Before and after treatment 14 days,determination of nutritional indicators,immune function,inflammatory markers and indicators of oxidative stress.Results Compared with before treatment,levels of total protein,albumin,transferrin and fibronectin in 2 groups after treatment increased,levels of IgM,IgG,CD4 +,CD8 +and CD4 +/CD8 +increased,levels of TNF-α,IL-8 and CRP decreased,levels of MDA,GSH and TAO decreased,levels of SOD increased(P<0.05), compared with the control group,levels of total protein,albumin,transferrin and fibronectin in the treatment group were higher,levels of IgM,IgG,CD4 +, CD8 +and CD4 +/CD8 +were higher,levels of TNF-α,IL-8 and CRP were lower,levels of MDA,GSH and TAO were lower,levels of SOD were higher (P<0.05).Conclusion Recombinant growth hormone has immune function protective effect on the COPD patients with type II respiratory failure in the process of breathing machine, which can improve the nutritional index and reduce the inflammatory reaction.

Objective:To investigate the expression of latent membrane protein-1(LMP-1),NET-1,and vascular endothelial growth factor(VEGF)in non-keratin nasopharyngeal carcinoma(NK-NPC)and its clinical significance.Methods :Sixty biopsy specimens from pathologically-confirmed NK-NPC patients,who were treated in the Affilitated Hospital of Nantong University from May 1999 to May 2003,were included in the present study.Using immunohistochemical techniques (Envison two-step),we examined the expression of LMP-1,NET-1 and VEGF protein in the specimens.The relationship between their expression and elnicopathological parameters and the prognosis was anayzed.Ten specimens of chronic nasopharyngitis served as control.Results:(1)The positive rates of LMP-1,NET-1 and VEGF in NK-NPC were significantly higher than those in the chronic nasopharyngitis(P0.05).(3)NET-1 and VEGF expression in NK-NPC specimens were positively correlated with lymph node metastasis and distant metastasis(P

Objective s To investigate the value of Doppler ultrasound in diagnosing active sacroiliitis of axial spondyloarthropathy (axSpA) patients.Methods The Doppler ultrasound and MRI data of 51 patients with early axSpA was retrospectively analyzed.According to MRI results,axSpA patients were divided into active sacroiliitis (active group) and inactive sacroiliitis (inactive group).The color flow display and blood flow resistance index (RI) were compared.Considering MRI as the diagnostic standard,ROC curve was used to evaluate the diagnostic efficacy of RI in detecting active sacroiliitis.Results There were 32 cases wth 58 joints (6 cases were single active sacroiliitis) in activity group and 19 cases with 38 joints in inactivity group.The flow signals demonstration rate of sacroiliac joint in activity group (51/58,87.93％) was higher than that in inactive group (26/38,68.42％;x2 =5.505,P=0.019).There was no statistical difference of the indegree of blood flow between the two groups (Z=-1.93,P=0.053).RI in active group (0.59±0.08) was lower than that in inactive group (0.71±0.09;t=-6.04;P＜0.001).Taking RI=0.64 for diagnosis of active sacoriliitis in axSpA patients,the sensitivity,specificity and accuracy rate were 80.8％,74.5％ and 78.7％,respectively.Conclusion Through observing abnormal blood flow signals around and internal the sacroiliac joints,ultrasonography can response active sacroiliitis in axSpA patients with higher accuracy.

Objective To explore the effect of time management on the on-time rate of implementation of the first selective operation.Methods Five hundred and two selective operations from January to May of 2013 without time management were set as control group, while another five hundred and twenty with time management as experiment group. The two groups were compared in terms of on-time rate of the first selective operation, time for nurse’s extra shift, number of nurses at extra shift, numbers of operations and satisfaction level.Results After time management, the experiment group was significantly better than the control in terms of the on-time rate of operations, time for nurse’s extra shift, number of nurses at extra shift, numbers of operations and satisfaction level (all P<0.01).Conclusion Time management used in the operation room can significantly improve the on-time rate of selective operations and doctors’satisfaction and work efficiency, thus decrease nurses’overworking time.
