Objective To investigate the clinical effect of improved nursing intervention in blood glucose control of critical patients. Methods By means of historical control, 258 critical patients undergone intense insulin therapy were divided into the control group (n = 126) and the test group (n = 132). The control group was given conventional intensive insulin therapy. The test group was given improved guidelines on the use of insulin and improved nursing intervention. The following indexes of the two groups were documented and compared: the time required to achieve target blood glucose level [(11.95 ± 1.97) h vs (18.85 ± 3.59) h, t =19. 237 3 ,P ＜0. 01]; frequency of blood glucose measuring in four days, the range of everyday blood glucose and the occurrence of hypoglycemia during therapy. Results The test group had shorter time required to achieve target blood glucose level, lower frequency of blood glucose measuring, less fluctuation range of blood glucose and reduced occurrence of hypoglycemia during therapy than the control group (P ＜ 0. 01). Conclusions The use of improved guidelines on the use of insulin and improved nursing intervention in intensive insulin therapy of critical patients can effectively control blood glucose, reduce frequency of hypoglycemia and improve prognosis.

Objective: To investigate the relationship between P27，P53 and PCNA expression in human gastric carcinoma tissues and clinicopathological parameters. Methods: The expression of P27，P53 and PCNA in 62 human gastric carcinoma tissues was examined with immunohistochemistry SP method. Results: Positive rates of P27，P53 and PCNA expression were 37.1％, 40.4%，83.9％. P27 expression was related with Bormann type, infiltrative depth, lymph node and distant metastasis and clinical stage. P53 expression was related with sex of patients, distant metastasis and clinical stage. PCNA expression was related with age of patients and infiltrative depth of tumor. P27 positive expression group was higher than negative group as to 5-year survival. P27 expression was in reverse relation with PCNA expression. Conclusion: The expression of P27, P53 and PCNA may be regarded as an important marker in judging malignant degree of gastric carcinoma,distant metastasis and prognosis.

OBJECTIVETo explore whether there could be proliferative cells in the cochlea of the newborn rat or not and what kinds of cells should be differentiated from the proliferative cells while to study the effect of the growth factors on the proliferative cells and the ultrastructure of the proliferative cells.

METHODSThe Corti's organ were dissected from the cochlea of newborn SD rats and cultured. The proliferative condition of cells was tested by infusing the 5-bromo-2-deoxyuridine (BrdU) into the culture medium. And the variety of the spheres and differentiated cells were identified by immunohistochemistry. Corti's organ from forty-eight surface preparations was randomly divided into 4 groups: control group; epidermal growth factor (EGF) group; basic fibroblast growth factor (bFGF) group and EGF + bFGF group, with each group including 12 Corti's organ, and then the number of cell spheres of each Corti's organ was counted. The data was statistically analysed with ANOVE. Finally, the proliferative cells were observed under scanning electron microscope and transmission electron microscope.

RESULTS(1) The cell spheres can be observed in the cell culture of the Corti's organ. In present experiment, 90.1% of cells in spheres were labeled by BrdU, while nestin of spheres, the marker of hair cells--myosin 7A, espin, and phalloidin of the differentiated cells were positive. The marker of neuron-microfilament-M was also positive, and some differentiated cells were labeled by myosin 7A and BrdU, espin and BrdU, NF-M and BrdU at the same time. (2) The average number (x +/- s) of spheres from single Corti's organ was: 45.3 +/- 23.00 in control group, 86.2 +/- 34.1 in EGF group, 96.5 +/- 33.6 in bFGF group and 131.2 +/- 47.00 in EGF + bFGF group. There were significant differences between other groups respectively (P < 0.05) but there was no significant differences between EGF group and bFGF group (P > 0.05). (3) Scanning electron microscopy and transmission electron microscopy showed that cells of the spheres were round and had the same size and many short and thin microvilli on the surface of these cells. The cytoplasm were rich of organellae such as endoplasmic reticulum, mitochondrion, and cytoskeleton such as microfilament, microtube, et al. Tight junction, desmosomes and gap junctions between two adjacent cells were seen.

CONCLUSIONSThe proliferative cells are observed in the cochlea of the newborn rats and proliferative cells could differentiated into hair cells with bundles-like structure and neuron. Both EGF and bFGF possess the promoting effects for proliferation on the proliferative cells while the proliferative cells have characters of earlier immature cells.

OBJECTIVESTo understand the relation between nitric oxide (NO) level in seminal plasma and male fertility.

METHODSThe levels of NO in seminal plasma of 174 fertile males and 217 abnormospermia patients were measured by using the reductase of nitric acid, Greiss reagent and spectrophotometry.

RESULTS1. NO was found in all 174 samples (20-49 years) of fertile males which was (27.78 +/- 5.81) mumol/L. The NO level in seminal plasma in fertile males was became higher after age 40, and there was no significant difference between 20-29-year-old [(26.25 +/- 5.52) mumol/L] and 30-39-year-old[(28.11 +/- 5.87) mumol/L]. But the group of 40-49-year-old[(30.17 +/- 6.14) mumol/L] had a higher level of NO in seminal plasma than 20-29-year-old (P < 0.05). 2. The seminal plasma samples from nine types of abnormospermia were measured, which all had a higher level of NO than fertile males. In abnormospermia, the level of NO in seminal plasma of the patients with single abnormality increased slightly, two abnormality obviously increased, and the highest level of NO in seminal plasma appeared in three abnormality.

CONCLUSIONSThis results confirmed that proper level of NO in seminal plasma may regulate the spermatogenesis.
