Non-invasive transcutaneous monitoring(TCM) of oxygen and carbon dioxide,with continuous,non-invasive characteristics,is in common use and significant in the neonatal intensive care unit (NICU),which can directly reflect critically ill newborns'changes of respiratory and circulatory function.This review describes how to use TCM appropriately,compares the advantages and disadvantages of TCM with other monitoring devices,introduces its application in neonatal transport and NICU.

Purpose:To study the salvage treatment of recurrent intermediate—high grade non Hodgkin lymphoma(NHL). Methods:24 cases of recurrent intermediate—high NHL were divided into two groups: 10 cases with poor prognostic factors in group one(G1), 14 cases without poor prognostic factors in group two(G2).All cases were treated with ifosfamide(IFO), mitoxantrone(Mx), pingyangmycine(PYM), prednisone(Pred) (IMPP). IFO 1.5 g/m 2 iv on days 1 to 4, and mesna iv at hours;0, 4, 8 Mx 8 mg/m 2 on day 1; PYM 5mg/m 2 im on days 8 and 15; and Pred 100mg/d po on days 1 to 5. Every 4 weeks as one cycle. Assessment was given after 2 cycles. Results:The total CR rate was 58.3%(14/24), RR 79.2%(19/24). The CR rate was 30%(3/10), RR 60%(6/10) in G1 and the CR rate was 78.5% (11/14), RR 92.8%(13/14) in G2 ,respeetively. The difference of the two groups in CR and RR was significant( P

Objective: To explore the efficacy and mechanism of warm needling moxibustion plus percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture (OVCF) due to kidney deficiency and blood stasis. Methods: A total of 70 OVCF patients were randomized into a control group and an observation group, with 35 cases in each group. The control group was given PKP treatment, and the observation group was treated with warm needling moxibustion on the basis of the treatment in the control group. The visual analog scale (VAS) and Oswestry disability index (ODI) were scored and the Cobb angle of fractured vertebrae was measured before and after treatment. The re-fracture rate of the adjacent vertebrae was recorded at 1-year follow-up. The serum levels of transforming growth factor (TGF)-β1 and omentin-1 were measured before and after treatment. Results: After treatment, the VAS and ODI scores in both groups decreased (all P<0.05), and all the scores in the observation group were lower than those in the control group (both P<0.05). After treatment, the Cobb angle of fractured vertebrae in both groups decreased (both P<0.05), and the Cobb angle in the observation group was smaller than that in the control group (P<0.05). At 1-year follow-up, the re-fracture rate of the adjacent vertebrae in the observation group was lower than that in the control group (P<0.05). After treatment, the serum levels of TGF-β1 and omentin-1 in both groups increased significantly (all P<0.05), and the serum levels of TGF-β1 and omentin-1 in the observation group were higher than those in the control group (both P<0.05). Conclusion: The treatment of warm needling moxibustion plus PKP can relieve pain, improve dysfunction, promote healing of the injured vertebrae, and reduce the re-fracture rate of the adjacent vertebrae in patients with OVCF due to kidney deficiency and blood stasis, which may be related to the increase of serum TGF-β 1 and omentin-1 levels.

In the scientific,systematic,practical and feasible principles,the quality control needs and management needs of health authorities and medical institutions were analyzed.The study probed into the real-time monitoring functions of existing hospital information systems and information products of IT technology firms,and the feasibility of setting up key monitoring points during medical service processes.685 real-time monitoring indicators have been set up for real-time monitoring of medical process quality.

Spermatogenesis is a process consisting of spermatogonial proliferation, spermatocytic meiosis, and spermiogenesis, and is also considered to be a process in which heterochromatins gradually aggregate and finally reach a highly condensed formation in the sperm head. Recent studies show that epigenetic regulation plays a key role in spermatogenesis. This review discusses the mechanisms of epigenetic regulation in spermatogenesis in three aspects, DNA methylation, histone modification, and noncoding RNAs. These factors are essential for spermatogenesis, fertilization, and embryogenesis by mutual regulation as well as by gene expression regulation, transposon activation, sex chromosome inactivation, and genome imprinting.

Objective To establish a new kinetic fluorimetry method for the determination of trace nickel in human hair samples. Methods The method was based on the catalysis of nickel on the oxidation of fluorescein(CF) by hydrogen peroxide in an almost neutral medium. As nickel is present, the fluorescence intensity of the solution decreases. Results The wavelength of excitation was 492 nm and the wavelength of emission was 516 nm. The reaction was optimized at 100 ℃ for 10 min. The linear range of determination was 4.0-80.0 ?g/L and the detection limit was 2.2 ?g/L . The RSDs and recovery rates of the method were 2.6%-3.2%, and 96.7%-102.8% respectively. Conclusion This method is simple, rapid and sensitive for the determination of trace nickel in human hair samples.

Objective:The study focused on detecting the expression of Twist,HIF-1? and HBx in primary liver cancer(PLC) and assessment their relativity.Methods:The expression of Twist,HIF-l? and HBx in 33 cases of PLC and thein paracancerous tissues were examinated with immunohistochemical location technique.Seventeen health control subjects were included in the study. Results:The incidence of Twist,HIF-1?and HBx expression was 93.9%,72.7% and 81.8% in 33cases of PLC,respectively.The positive percentage of Twist in paracancerous tissues was 54.5%.A significant difference was found between the expression of tumor and paracancerous tissures (P

Objective To study the effects of multi frequency tympanometry and acoustic stapedius reflexes on the diagnosis of the middle ear functions of infants.Methods Tympanometries with 226,678 and 1 000 Hz probe tones and 500 and 1 000 Hz acoustic stapedius reflexes were performed on infants at age 0~1 year.128 normal infants(256 ears) and 104 abnormal infants(168 ears) were tested with GSI Tympstar middle ear analyzer.Results The patterns of 226 Hz tympanograms were non-peaked,single-peaked and W-shaped.There were no significant differences between two groups of infants aged 0～6 months.The patterns of 678 Hz and 1 000 Hz tympanograms showed significant differences between two groups of infants aged 0～1 year.The outcomes of 500 Hz and 1 000 Hz acoustic stapedius reflexes showed no differences between the same age groups.There were significant differences between normal group and abnormal group.Conclusion Tympanometry with 678 Hz and 1 000 Hz probe tones can yield accurate diagnostic results in the assessment of the middle ear functions for infants younger than six months.The tympanometry with three frequency probe tones is sensitive to infants aged 6～12 months.The outcomes of acoustic stapedius reflexes at 500 and 1 000 Hz show no differences between the same age groups,but presences become more noticeable as a function of ages.
