Objective To discuss the effective measures for skin allergy caused by hyaline mem-brane after deep venous catheterization. Methods Patients (102 eases) were divided into the control group(50 cases) and the test group(52 cases).3M hyaline membrane was patched on the skin directly to fix the catheter after successful puncture in the control group.While in the test group 3M hyaline membrane was patched on the skin after 3M painless protective membrane was sprayed on the skin. Results The incidence of skin allergy in the test group was lower than that of the control group. Conclusions Spray of 3M painless protective membrane before usage of hyaline membrane to fix the catheter could prevent the incidence of skin allergy after deep venous catheterization.

Objective To evaluae possible association between interleukin-1 beta (IL-1?) gene exon 5 polymorphism and childhood asthma.Methods The study was conducted in two different groups: asthmatic children(n=55) and healthy children(n=35). The IL-1? gene exon 5 polymorphism was genotyped by polymerase chain reaction-restriction fragment length polymorphism analysis (PCR-RFLP). Results Frequencies of CC,CT and TT genotypes were 92.7%,7.3%,0, and frequencies of C,T allele were 96.4%,3.6% in asthmatic group. However, frequencies of CC,CA and AA genotypes were 85.7%,14.3%,0, and frequencies of C,T allele were 92.9% ,7.1% in healthy group. There were no significant difference in distribution of genotypes and allele frequencies between two groups.Conclusion IL-1? gene exon 5 polymorphism may not be associated with childhood asthma.

0.05).Conclusion PAF-AH-Ala379Val gene mutation is unrelated to bronchial asthma in children.

Objective To investigate the polymorphism of glutathione S-transferease P1 gene(GSTP1) and the association between the mutation and susceptibility in childhood asthma.Methods The distribute frequency of Ile105/Ile105,Ile105/Val105 and Val105/Val105 ge-notype in GSTP1 of 51 children with asthmatic and 40 normal children were studied with polymerase chain reaction-restriction tragment length polymorphism(PCR-RFLP).Results The frequencies of Ile/Ile Ile/Val,Val/Val genotype were 66.7%,27.4% and 5.9%,the frequencies of Ile,Val allele were 80.4% and 19.6% in the asthmatic group.But the frequencies of Ile/Ile,Ile/Val,Val/Val genotype were 90.0%,7.5% and 2.5%,the frequencies of Ile,Val allele were 93.8%,6.2% in control group.The frequencies Ile/Val,Val/Val genotype and Val allele in asthmatic group were more than that in control group.A significant difference was found in the frequency distribution of GSTP1 genotypes between two groups(?2=6.947 P

OBJECTIVETo investigate effects of the variation of immune function in high humidity environment in different time, and lay a foundation for further study of the related mechanism.

METHODThirty SD rats were divided into 3 groups (n = 10): 20 day group, 40 day group in 90% relative humidity chamber and control group in normal relative humidity. Peripheral blood and spleens were collected to detect the levels of T lymphocyte subsets by Flow Cytometery.

RESULTSIn peripheral blood of the 20 day group rats, the CD3+ %, CD4+ %, CD8+ % and CD4+/CD8+ were 52.91 +/- 6.27, 37.80 +/- 4.11, 14.85 +/- 3.73 and 2.72 +/- 0.82 separately. Expect CD3+ %, they all had significant differences (P < 0.05). In addition, the data of the 40 day group rats showed no diversity in statistics. In spleen, CD8+ % of the 20 day group rats was 6.23 +/- 2.87 with significant differences (P < 0.05) and IgG, IgA and IgM did not change a lot in blood serum of the high humidity groups except C3 of the 20 days group (P < 0.05).

CONCLUSIONIn high humidity environment, the immune function of the rats increased in the initial stage. As time went on, the immune function gradually went to normal level through the self adjustment.

OBJECTIVETo summarize the clinical manifestation and diagnosis of ganglioneuroma in spine and investigate the clinical effect of surgical treatment.

METHODSThe clinical data of 6 patients underwent a surgery for ganglioneuroma in spine from January 2008 to January 2015 were retrospectively analyzed. There were 4 males and 2 females, aged from 2 to 63 years old with an average of 34.6 years. The courses of disease were from 3 days to 17 years. Five patients complicated with superficial hypesthesia in correlative level of tumor, and the muscle strength under tumor plane had decreased at different levels, with the strength of grade II-IV. Two cases complicated with hypermyotonia and positive bilateral Hoffmann's and Babinski sign. Five cases were sporadic lesion in correlative spinal canal and one case complicated with the giant occupying lesion in thoracic cavity.

RESULTSSix operations had been performed including 5 en bloc and 1 subtotal resection. Postoperative pathological results showed tumor cells scattered or fasciculated inserted into Schwann cells in the stroma. In 2 patients complicated with radiculalgia before operation, 1 case was relieved and 1 was invariant after operation. All 4 patients with preoperative dyscinesia in the limbs obtained improvement after operation. All the patients were followed up from 0.3 to 6.8 years with an average of 2.5 years. At the final follow-up, according to ASIA grade, 5 cases were good and 1 case was invariant. During the follow-up, only 1 patient experienced chemoradiation because of merging ganglioneuroblastoma and receiving subtotal resection. No recurrence in other 5 cases.

CONCLUSIONGanglioneuroma is a benign and rare tumors in spine. Clinically, radicular pain and sensory-motor disorders are the main manifestations. Its diagnosis depends on pathological examination. Prognosis of surgical treatment is good.

pH, affects of different alkaline materials KOH, K 2CO 3, NaOH, Na 2CO 3 on the growth, and NaCl, KCl tolerance of 29 isolates from the saline and alkaline soils in Xinjiang and Qinghai Provinces of China and 1 type strain were studied. Results showed that only a few alkaliphilic actinomycetes were Na +-obligately dependent, and K +-sensitive. Some alkaliphilic actinomycetes were CO 3 2- -sensitive, and NaCl, KCl could inhibit their growth. 4 kinds of alkaline materials had no affect on growth of alkaliphilic Nocardiopsis, and these strains showed high tolerance to NaCl, KCl. So it was presumed that only K + and CO 3 2- obligately dependent alkaliphilic Actinomycetes maybe exist in alkaline environments.
