OBJECTIVE:
To analyze the nutritional status and nosocomial infection of nasopharyngeal carcinoma patients before and after the chemoradiotherapy treatment.
METHOD:
An analysis was made for the nutritional and nosocomial infection status of 82 cases before and after chemoradiotherapy treatment.
RESULT:
Statistically significant differences were revealed between indexes related with nutritional status such as body mass, hemoglobin, serum albumin before and after the treatment. Sixty-three patients occurred nosocomial infection. The infection rate was 76.83%. The main risk factor was oropharynx mucosal lesion and the rate is 92.68%. Isolates of 39 bacteria were found, of which Gram-negative organisms were 58.97%, Fungi were 30.77%, Gram-positive ones were 7.69%, Herpes zoster were 2.56%.
CONCLUSION
Chemoradiotherapy has negative influence on nutritional status of patients. Medical personnel should pay attention to patients' nutritional status and do a good job of nutritional status monitoring, nutrition support, dieting guidance, reducing side effects, in order to improve the patient's tolerability and quality of life. The nosocomial infection rate of Gram-negative bacteria of oropharyngeal mucosal is the highest in patients with advanced nasopharyngeal cancer during chemoradiotherapy. It is very important for us to prevent and control nosocomial infection.

Objective To explore the relationships between the sleep/wake-up patterns and temperament in preterm infants.Methods The developmental characteristics of sleep/wake-up patterns and temperament in preterm infants aged 4 months at corrected gestational age in their own home environments were described.The 23 relatively low-risk preterm infants were enrolled in this study.The sleep/wake-up data was collected with actigraphy.The temperament was assessed by Chinese Infant Temperament Questionnaire.Results Among the 23 infants,there were 13 coordinated difficult(D) type and 10 coordinated easy(E) type.The number of night wake-up in the coordinated D-type preterm infants[(2.78 ±0.01) times] were significantly more than that of coordinated E-type ones[(2.60 ± 0.03) times] (t =3.285,P =0.001).The longest continuous sleep time of coordinated D-type preterm infants [(4.20 ± 1.21) h] was significantly less than that of coordinated E-type ones[(4.41 ± 1.14) h] (t =3.374,P =0.001).There were no significant differences in daytime sleep duration,the number of naps,bedtime,sleep latency,nighttime sleep duration,the 24 hour sleep duration and morning awaking time between the two groups (all P > 0.05).After the sex factor was controlled,there was a positive correlation between emotional nature and sleep latency at night (r =0.599,P =0.032).There was also positive correlation between persistence and the number of naps in daytime (r =0.439,P =0.035).Conclusions Preterm infants with different temperament types have different number of night wake-ups and the longest continuous sleep time.The emotional nature and persistence are associated with sleep latency at night and number of naps in daytime respectively.The parents of preterm infants should change their child rearing behaviors to improve sleep quality of the preterm infants.

Objective To investigate the effects of perfusion pressure with a cardioplegic solution on endothelium-dependent relaxation and smooth muscle function of porcine coronary artery. Methods The hearts were infused with a modified St.Thomas’ hospital solution at the pressures of 40, 60 and 80 mmHg. The distal part of porcine left anterior descending coronary artery (LAD) having a diameter of 1.0-1.5 mm, was dissected free from the surrounding tissue, cut into 1 mm long segments, immediately transferred to organ baths for the evaluation of endothelial and smooth muscle function. Results Smooth muscle function was not affected after cardioplegic flushing at the pressures used in this study. The maximal endothelium-dependent relaxations of the vessels in 40 and 60 mmHg groups were not reduced compared to fresh segments . The maximal EDR was significantly reduced to (90.8?2.2)% (P

AIM:To explore whether histamine can regulate the expression of early growth response factor-1 (Egr-1) in the cerebral cortex astrocytes.METHODS:Normal wild-type (WT) mice, histidine decarboxylase knockout ( HDC-KO) mice and histamine treated HDC-KO mice were sacrificed for extracting the total RNA of the cerebral cortex. Primary cultured rat cortical astrocytes were treated with histamine at concentrations of 10 -8 , 10 -7 , 10 -6 , 10 -5 or 10 -4 mol/L for 15, 30, 60, 120 or 240 min.H1 or H2 receptor antagonists were pretreated for 15 min before histamine treat-ment.After histamine treatment, the cell total RNA or protein was extracted.The expression of Egr-1 at mRNA and protein levels was determined by real-time PCR and Western blot.RESULTS:The mRNA level of Egr-1 in cerebral cortex of HDC-KO mice was significantly lower than that in WT mice, while exogenous histamine induced the mRNA expression of Egr-1 in HDC-KO mice.In cultured astrocytes, histamine induced the mRNA expression of Egr-1.The maximum increase in the mRNA level of Egr-1 was produced by histamine at concentration of 10 -5 mol/L.In addition, histamine-induced Egr-1 mRNA accumulation peaked at 30 min after commencing stimulation, while histamine significantly increased Egr-1 protein expression at 60 min.Furthermore, histamine-induced Egr-1 expression was inhibited by H1 receptor antagonist but not H2 receptor antagonist.CONCLUSION:Histamine up-regulates the Egr-1 expression in cerebral cortex and cultured astrocytes, which may attribute to H1 receptor activation.

To establish the quality standard for Pingyou granules. Methods: Paeoniae radix, Carthamus tinctorius, Coicis semen and Nutgrass galingale rhizome were qualitatively identified by TLC. The content of peoniflorin was determined by HPLC. The separation was performed on a Lichrospher-C18 (250 mm × 4. 6 mm, 5 μm) column with the mobile phase of methanol-acetic acid (24∶76). The detection wavelength was 232nm. Results:Paeoniae radix, Carthamus tinctorius, Coicis semen and Nutgrass galingale rhizome could be identified by TLC without any interference from the negative control. The linear range of peoniflorin was 6. 560-104. 920 μg·ml-1(r=0. 999 9) with the average recovery of 98. 77%(RSD=2. 73%,n=9). Conclusion:The qualitative identifi-cation is specific and reproducible, and the quantitative method is simple, accurate and reliable, which can be used in the quality con-trol of Pingyou granules.
