5.Analysis of the quality of life of 230 very low birth weight infants followed up to 6 months of corrected age
Journal of Clinical Pediatrics 2016;34(3):176-180
Objective To analyze the short term prognosis of very low birth weight (VLBW) infants. Methods The clinical data of VLBW infants who were hospitalized from December 2013 to December 2014 and followed up to 6 months of corrected age were retrospectively analyzed. Results A total of 230 VLBW infants were enrolled. Thirty infants (13.0%) died during hospitalization, 40 infants (17.4%) were given up the treatment, 60 infants (26.1%) were improved at discharge, and 100 infants (43.4%) were cured at discharge. In the 30 cases of death, causes of death were mainly neonatal respiratory distress syndrome (18 cases), pulmonary hemorrhage (5 cases), and sepsis (3 cases). In the 200 survived infants at discharge, at 6 months of corrected age of follow-up, 13 infants (6.5%) were lost to follow-up, and 54 infants (27.0%) died, among whom 40 infants died because of giving up therapeutic intervention due to economic factor or discharges without permission. At 1, 3, 6 month of follow-up, the length and weight of VLBW infants were gradually approaching normal, and, however, at 6 months of corrected age, the length and weight of VLBW infants were still obviously below the children’s growth standard. The length of VLBW infants was more deeply below the growth standard than the weight. In 109 infants who had fundus ophthalmoscope, 21 cases had retinopathy of prematurity (ROP) I, and 7 cases had ROP II. In 98 infants who had the hearing screening test, 5 cases failed in one ear and 11 cases failed in both ears. In 95 infants who had the head magnetic resonance imaging (MRI) examination, 10 cases had intracranial hemorrhage and 9 cases had premature brain injury. In 49 infants who completed the neonatal behavioral neurological assessment (NBNA) at corrected age of 42 weeks, the scores were all lower than 35. In 36 infants who were assessed by Gesell developmental scale at the 3 months of corrected age, 11 cases had mild developmental delay and 2 cases had moderate developmental delay. In 24 infants who were assessed at the 6 months corrected age, only 2 cases had mild developmental delay. VLBW infants had a rapid progress in social contact, social behavior, and gross motor movement. Conclusions Economic, neonatal respiratory distress syndrome, pulmonary hemorrhage, and sepsis are pivotal factors for the survival and quality of life of VLBW infants. The surviving VLBW infants have catch-up growth and development.
6.Comparison of prognostic factors and outcome of patients with advanced cervical cancer between Han and Uygur in Xinjiang district
Chinese Journal of Radiation Oncology 2012;(6):540-542
Objective To compare the treatment outcome and prognostic factors in patients with advanced cervical cervical cancer between Han and Uygur in Xinjiang district.Methods 204 patients with advanced cervical cancer were retrospectively analyzed.Eighty patients were Han 80 and 124 were Uyghur.100 patients received radiotherapy alone and 49 with concurrent radiochemotherapy,and 55 had brachytherapy followed by surgery.The survival rate was calculated by Kaplan-Meier method and the difference was compared by Logrank test.Multivariate analysis was performed using Cox regression model.Results The follow-up rate was 97.5%.The number of patients with at least 5 years of follow up was 102.The 1-,3-and 5-year overall survival rates in Han and Uygur patients were 81.2%,66.3%,51.4% and 83.4%,62.8%,49.2%,respectively (x2 =3.21,P =0.273).Univariate analysis showed that parity,geographical distribution,pathological type,clinical stage,lymph node involvement and treatment were prognostic factors for overall survival (x2 =2.35,11.34,7.12,6.73,4.79,13.60,P=0.049,0.029,0.031,0.037,0.041,0.021).Multivariate analysis showed that parity,geographical distribution,pathological type,clinical stage,lymph node involvement and treatment were independent prognostic factors for overall survival (x2 =8.36,24.94,10.69,5.63,9.50,P =0.002,0.001,0.021,0.018,0.031).Conclusions There is no significant difference in overall survival rate of patients with advanced cervical cancer between Han and Uighur.Patients with parity more than or equal to 3 times,advanced clinical stage or adenocarcinoma have poor prognoses.
7.The correlation between serum concentration of vitamin A and NRDS in preterm infants
Journal of Clinical Pediatrics 2015;(8):734-737
ObjectivesTo observe correlation between serum vitamin A status and prevalence or severity of NRDS. MethodsRecruited into this study were 166 preterm infants admitted to our neonatal department. The serum concentration of vitamin A was measured, and the prevalence of NRDS at different levels of vitamin A was compared. According to the clinical manifestation and X-rays, there were 30 infants diagnosed as NRDS. Another 30 patients from the rest 133 infants without NRDS were randomly selected as control group according to the gestational ages, then the difference between NRDS group and control group were observed according to gestational ages. The 30 preterm infants with NRDS were divided further into mild group (in-cluding stagesⅠandⅡ,n=18) and severe group (including stageⅢ andⅣ,n=12) according to ifndings chest X-ray, then the difference between these two groups were observed.ResultsIn the 166 preterm infants recruited, 65/166 had serum vitamin A lower than 0.35 μmol/L, in which 14/65 (21.54%) were NRDS patients. Another 93/166 patients had serum vitamin A ranged from 0.35 μmol/L to 0.7 μmol/L, in which 15/93 (16.13%) were NRDS patient. The rest 8/166 had serum vitamin A higher than 0.7 μmol/L, in which 1/8 (12.50%) were NRDS patient. However, the differences between each two groups were not signiifcant. When gestational ages ranged from 34 to 37 weeks, the serum concentrations of vitamin A of NRDS group were lower than that in controls (P<0.05). No signiifcant difference between the serum concentrations of vitamin A and the severity of NRDS were ob-served (P>0.05).ConclusionsThe prevalence of NRDS for those preterm infants lacking of vitamin A was tended to increase. And the late preterm infants (34 w≤ GA <37 w) with vitamin A deifciency are prone to NRDS.
8.Predictors and risk factors of poor outcome in full-term newborns with severe hyperbilirubinemia
Journal of Clinical Pediatrics 2015;(2):136-140
Objective To investigate the risk factors and predictors of poor outcome in full-term neonates with severe hyperbilirubinemia. Methods Data were retrospectively collected from 326 neonates with severe hyperbilirubinemia hospitalized between January 1, 2012 and December 31, 2012. Results A total of 326 full-term neonates with severe hyperbilirubinemia were included in this study (181 males and 145 females). The average gestational age was 39.12±1.17 weeks. Two hundred and sixty (260) cases were followed up successfully by phone while 66 cases were lost to follow-up. Infection (74.40%) and hemolytic disease (51.19%) were the main causes of severe hyperbilirubinemia. Multiple factors regression analysis found that threshold TSB was an independent risk factor of poor outcome (OR=2.02, 95%CI:1.13~3.62, P=0.018). The outcome of neonates with BIND scored between 0-6 had poor prognosis and some of them were reversible, and the outcome in those scored between 7-9 were of worse prognosis. Threshold TSB, USB and B/A ratio in group of poor outcome were signiifcantly higher than those in other groups and their area under the ROC curve evaluating the prognosis was 0.682, 0.671 and 0.698, respectively. With TSB at 474.5 μmol/L, UCB at 449.15 μmol/L and B/A at 0.923 mg/g, Youden index was the higest. The results of BAEP, OSE, MRI and NBNA were not signiifcantly different between groups with or without poor outcome. Conclusions Threshold TSB is an independent risk factor of poor outcome in full-term newborns with severe hyperbilirubinemia. BIND score is a very good predictor of outcome. TSB threshold, USB and B/A ratio are the predictors of outcome, but their diagnostic values are limited. NBNA, hearing screening and hyperintense globus pallidus on T1W1 in the acute phase of jaundice might not related with neurologic prognosis.
9.Effect of acclimation training on physiological changes in a randomized controlled trial in hot-humid environment.
Chinese Journal of Applied Physiology 2014;30(6):544-548
OBJECTIVEThis study was aimed to explore the physiological changes and the effect of heat acclimation training via a randomized control trial study.
METHODSForty healthy male volunteers were chosen and divided into experimental group and control group randomly. Those in experimental group received heat acclimation training including but not limited to meditation, unarmed run, yoga, and stepping in hot lab environment. And then, subjective feeling, rectal temperature, average skin temperature, and sweat electrolytes concentration were detected in order to describe their physiological changes. Before and after the training, both groups received some tests and their 3 000 m run-race time, nervous reaction time and subjective perception scores were recorded to evaluate the effect of acclimation training.
RESULTS(1) There was no difference in 3 000 m between the 2 groups in the same environment. Subjects' 3 000 m race time in experimental group was obviously shortened than that in control group in room temperature environment (t = 2.326, P < 0.05). And subjects' 3 000 m race time in experimental group was obviously shortened than that in control group in hot-humid environment (t = 4.518, P < 0.01). (2) Subjects' reaction time (RT) in experimental group was shortened than that in control group in room temperature environment (Z = 11.258, P < 0.05). And Subjects' RT in experimental group was sharply shortened than that in control group in hot-humid environment (Z = 6.519, P < 0.01). (3) No difference between the experimental and control groups was observed in subjective perception score (SPS) in room temperature environment. But subjects' SPS in experimental group was obviously lowered than that in control group and in hot-humid environment (t = 17.958, P < 0.01).(4) Anal temperature (AT) was lowered during training, while the change of mean skin temperature (MST) was not significant. Sweat sodium concentration (SSC) was lowered during training. SPS continued to decrease and entered plateau on the 13th day after training.(5) After acclimation training, the working capacity of the experimental group in hot-humid environment was over 85% of that in room temperature environment. While subjects' working capacity in control group in hot-humid environment was about 80% of that in room temperature environment.
CONCLUSIONHot-humid environment acclimation training improved the working capacity. After training, subjects' working capacity in hot-humid environment remained over 85% of that in room temperature environment, which was higher than that of those subjects who did not take part in training.

10. Determination methods for in vitro deposition of metered dose inhalers: Differences of three impactors
Journal of International Pharmaceutical Research 2016;43(5):961-970
Objective To analyze and compare fine particle fraction (FPF) and particle size distribution (PSD) measured by twin-stage impactor(TSI), Andersen cascade impactor (ACI) and next generation pharmaceutical impactor(NGI). Methods Selfmade metered dose inhaler(MDI) of fluticasone propionate was selected as the model drug, and the FPF and PSD were determined by TSI, ACI and NGI. Results The device of TSI was simple, and fine particle drug dose with less than 6.4 micrometer aerodynamic diameter size was acquired quickly, and the recovery rate was relatively high under the good seal, but aerodynamic diameter distribution was not obtained. In contrast, both the aerodynamic diameter and particle size distribution were obtained with ACI and NGI. Different from ACI, for NGI it was not necessary to wash the sieves, although NGI is heavy. So, the operation of NGI is simpler. Conclusion NGI can be chosen as the priority for the determination of the aerodynamics related parameters.
