1.Prevention and treatment of low temperature of early newborn infants
Chinese Journal of Applied Clinical Pediatrics 2017;32(2):158-160
Early newborns,especially premature and very low birth weight infants (VLBWI)are vulnerable to low environmental temperature and/or other factors at birth,they may be insufficient to maintain core body and can cause hypothermia which leads to a variety of disease,affecting their life quality.As the birth rate of premature newborns and VLBWI are increasing in China these years,newborns temperature management have become significant for decreasing newborn's mortality.The main causes for hypothermia are low environmental temperature,insufficient calorie intake,premature newborns,low birth weight and other diseases.Studies shown that the prevention strategies of neonatal hypothermia include:(1) thermal neutral zone;(2) incutators and radiant warmers;(3) plastic hoods and plastic blankets;(4) kangaroo care;(5) breast feeding.

Cerebellum connects with each part of the auditory pathway directly or indirectly, forming the anatomical basis for a cerebellar role in auditory process. Functional imaging studies and clinical observations provide more abundant support for this view. Tinnitus is one of the most common clinical manifestations when the auditory system is impaired and remains unsolved. Basic science researches in neurotransmitter chemistry and molecular biochemistry, together with functional imaging studies, indicate that cerebellum might contribute to the pathophysiology of tinnitus. In this review we summarize the current understanding of cerebellar role in auditory process and tinnitus.

Objective To detect the expression of type Ⅰ collagen, type Ⅲ collagen, prolyl-4-hydroxylases (PH4) and matrix metalloproteinase 1 (MMP-1) in sacral ligament fibroblasts under stress, to understand the collagen synthesis and metabolism in stress situations change. Methods Eight patients who underwent abdominal hysterectomy for uterine benign disease were enrolled in this study. Primary sacral ligament fibroblasts were isolated by explant. After mechanical loading, gene expression of type Ⅰ , Ⅲ collagen, PH4 and MMP-1 were measured. Results Stress of 8% continuing for 24 hours, collagen Ⅰ (1. 13 ± 0.24), collagen Ⅲ (1.05 ± 0. 31) mRNA expression and PH4 expression (1.11 ± 0. 31) compared with static groups (1) showed increasing trends;when the stress were 4% and 12%, collagen Ⅰ (0. 86 ± 0. 26 and 0. 85 ± 0. 25), collagen Ⅲ showed increasing trends (0. 74 ± 0. 29 and 0. 83 ± 0. 38) mRNA expression were decreased. After removal of the stress, in the stress of 4% for 1 hour, collagen Ⅰ (0.79±0.40, 0.97±0.24 and 1.46 ±0.75), collagen Ⅲ (0.86±0.40, 0.99±0.60 and 1.59±0.82) and PH4 (1.11 ±0. 51, 1.17 ±0. 54 and 1.37 ±0. 39) mRNA expression increased gradually. In 8% stress group, collagen Ⅰ mRNA expression (1.16 ± 0. 62, 1.01 ± 0. 51 and 1.05 ± 0. 80) reached the peak in day 1, and collagen Ⅲ (0.99 ±0.69, 1.59 ±0.55 and 1.03 ±0.91) and PH4 (1.05 ±0.31, 1.07 ±0. 80 and 0. 85 ±0. 31) mRNA expression reached the peak in day 2, then decreased. 4% and 8% of the stress with time after the change, MMP-1 mRNA expression have peaked at day 1. Conclusions Moderate stress could contribute to pelvic floor collagen synthesis, too much or too little stress is not conducive to the synthesis of collagen. Collagen Ⅰ and collagen Ⅲ on the stress response may be different, the former have faster reaction than the latter. PH4 were involved in the synthesis of collagen, while MMP-1 may play a role in collagen degradation.

Objective To investigate the prevalence, clinical characteristics and antibiotic resistance of Haemophilus influenzae (HI) in children with acute respiratory tract infection in Suzhou. Methods Data of sputum culture of 3 167 hospitalized childhood patients with acute respiratory tract infection from January 2006 to December 2007 were collected. The incidence of positive HI and the rate of resistance to different antibiotics were calculated and beta-lactamases of the strains were detected. Results About 4.4% of total 3 167 eases were infected with HI. The infection rate was related with season and sex, more frequent between February and June, more common in boys than girls. Children younger than three years old were likely to be infected by HI, eompared with other age groups. The beta-lactamase positive rate of HI was 31.4%. The resistance rates to ampicillin, SMZ + TMP, chloramphenicol, cefaclor, ceftazidime, tetracycline and ampicillin/sulbactam were 29.6% ~ 31.9%, 66.2% -73.9%, 19.7% ~ 15.9%, 2.8% ~ 14.5%, 2.8% ~0、 28.2% ~ 2.9% and 4.2% ~ 1.4% respectively. Isolates resistance to cefuroxime、 ceftriaxone、 imipenem、azithromycin and ciprofloxacin were not found. Conclusions The infection of HI in children with actue respiratory tract infection is closely related with season and sex in Suzhou. Children younger than three years old are at high risk. The beta-lactamase positive rate of HI was high and increased rapidly. Resistance rate to azithromycin, SMZ + TMP and chloramphenicol was high, some isolates were resistant to the second, third generation of cephalosporin. Monitoring the antibiotic resistance of H! should be emphasized.
