Objective To investigate pulmonary function in terms of tidal respiration and the influencing factors on it in ＜ 34 weeks premature infants with RDS at corrected gestational age of 40 weeks.Methods A total of 49 of ＜ 34 weeks premature infants with RDS (RDS group) and 36 of ＜ 34 weeks premature infants without RDS (non-RDS group) followed throughout entire twelve months were collected fromn December 2013 to October 2015.Of them,35 RDS patients and 20 non-RDS patients had the pulmonary function examination.A total of 26 full term infants with hyperbilirubinemia (full term group) were recruited for comparison study.The differences in parameters of tidal respiration were compared among the three groups.The RDS patients were further divided into the mild RDS subgroup and severe RDS subgroup according to the severity of illness.Result ①The TPEF [(0.17 ± 0.04) s vs.(0.23 ± O.09) s],VPEF [(6.74±2.70) mLvs.(9.33±2.92) mL],TPEF/TE [(29.06±4.21)％ vs.(38.27± 7.16) ％],VPEF/VE [(32.54 ± 4.43) ％ vs.(39.64 ± 5.88) ％] in RDS group were significantly lower than those in full term group (P ＜0.05).The TPEF [(0.19 ±0.06) s vs.(0.23 ±0.09) s],TPEF/TE [(30.31 ±11.53)％ vs.(38.27±7.16)％],VPEF/VE [(34.39±8.44)％ vs.(39.64±5.88)％] in non-RDS group were significantly lower than those in full termn group (P ＜ 0.05).The TPEF,TPEF/TE,VPEF/VE in RDS group were lower than those in non-RDS group,but the differences were not significant (P ＞ 0.05).②The TPEF,VPEF,TPEF/TE,VPEF/VE in mild RDS group were higher than those in severe RDS group,but the differences were.not significant (P ＞ 0.05).③ Logistic regression analysis indicated that the gestational age was the protective factor of pulmonary function in premature infants with RDS.Conclusions Small airway resistance in ＜ 34 weeks premature infants with RDS is higher than that in full term infants.There was no significant difference in pulmonary function between RDS premature infants and non-RDS premature infants.The gestational age was the influencing factor of pulmonary function in premature infants with RDS.

Objective To explore how the severity of periventricular-intraventricular hemorrhage (PIVH)impact on physique and neurodevelopment in premature infants.Methods A total of 80 preterm infants with PIVH admitted to NICU of Qingdao Women and Children's Hospital from December 2013 to June 2015 were eligible.According to the Papile classification,the premature infants were divided into 4 groups.They were grade Ⅰ PIVH group,grade Ⅱ PIVH group,grade Ⅲ PIVH group and grade Ⅳ PIVH group.The infants with grade Ⅰ PIVH and grade Ⅱ PIVH belong to the low-grade PIVH group.The infants with grade Ⅲ PIVH and grade Ⅳ belong to the severe-grade PIVH group.All of them were regularly followed up for 12 months.Neurodevelopmental outcomes of infants at 6 and 12-month correction age were assessed by using the 20 items neuromotor assessment applying for 0-1 year old and the Bayley scales of infant development-Ⅱ.The differences in physical and neurophysical development of premature infants among 4 groups were compared.Results There were no significant differences in physical growth indicators such as body weight,body length and the incidence of weight growth retardation among 4 groups (all P＞0.05).The incidence of neurobehavioral abnormalities in infants with grade Ⅲ-Ⅳ PIVH was significantly higher than that of infants with grade Ⅰ-Ⅱ PIVH at 12-month correction age (21.05％ vs 3.28％,x2 =4.284,P=0.038).Physical development index(PDI) of grade Ⅰ-Ⅱ PIVH infants was significantly higher than that of grade Ⅲ-Ⅳ PIVH infants at 6-month correction age(F=11.500,P＜0.05).At 12-month correction age,grade Ⅰ-Ⅱ PIVH infants showed a significant higher mental development index(MDI) scores and PDI scores than those of grade Ⅲ-Ⅳ PIVH infants(F=14.227,16.515,all P＜0.05).Of the 80 cases assessed,infants with grade Ⅲ-Ⅳ PIVH had significantly higher rates of cerebral palsy(21.05％ vs 1.64％,x2 =6.300,P=0.012) and developmental delay (26.32％ vs 4.92％,x2=5.185,P=0.023) compared with grade Ⅰ-Ⅱ PIVH infants.Conclusions The severe PIVH can have negative effect on the neurodevelopmental outcomes of preterm infants and might induce mental retardation,cerebral palsy and other neurodevelopmental disabilities.Therefore,the regular follow-up and early intervention in preterm infants with PIVH should be implemented to improve the quality of their lives.

Objective To investigate pulmonary function of tidal respiration in late premature infants with non-mechanical ventilation treatment at corrected gestational age of full term. Methods A total of 26 late premature infants with non-mechanical ventilation treatment at corrected gestational age of full term were collected from Qingdao Women and Children′s Hospital between April and December 2013,and saved as the late premature infant group. Also, a total of 31 full term infants with hyperbilirubinemia or neonatal ABO hemolytic disease were recruited and treated as the full term group. Then the parameters of pulmonary func-tion of tidal respiration were compared between the two groups. The late premature infant group was equally allocated into extrauterine growth retardation and non-extrauterine growth retardation groups according to the increase in weight and the ratio of time to peak tidal expiratory flow and total expiratory time(TPEF/TE) and the ratio of expiratory volume at peak tidal expiratory flow and total expiratory volume( VPEF/VE) were respectively compared in these two groups. Another correlation analysis between body weight and TPEF/TE was carried out in the non-extrauterine growth retardation group. Results (1)Gestational age difference had no significant significance between late premature infant group and full term group ( P <0. 05 ) . The body weight[(2. 39 ± 0. 44)kg vs. (3. 21 ± 0. 43) kg] and height[(46. 51 ± 3. 22) cm vs. (50. 16 ± 2. 14) cm] in late premature infant group were still lag behind that in full term group and the difference had significant significance(P<0. 05,respectively). (2)The comparison of parameters of pulmonary function of tidal respi-ration:the TPEF/TE [ ( 41. 74 ± 10. 94 )% vs. ( 48. 17 ± 11. 79 )%] , VPEF/VE [ ( 42. 66 ± 9. 66 )% vs. (48. 31 ± 9. 94)%],VPEF[(8. 02 ± 2. 85) ml vs. (10. 23 ± 3. 56) ml] and minute ventilation[(0. 76 ± 0. 23) L/min vs. (1. 00 ± 0. 44) L/min] in late premature infant group were significantly lower than those in full term group(P<0. 05,respectively). (3)The TPEF/TE and VPEF/VE all had significant significance in both late premature infant group and full term group(late premature infant group:r=0. 958,P=0. 000; full term group:r=0. 950,P=0. 000). (4)The TPEF/TE and VPEF/VE in non-extrauterine growth retardation group were closer to those in full term group. The TPEF/TE and VPEF/VE in extrauterine growth retardation group were lower than those in non-extrauterine growth retardation group(t= -2. 775,-2. 109,P=0. 011, 0. 047). Conclusion Airway(especially small airway) resistance of late preterm infant group is higher than that of term infants. Extrauterine growth retardation influences the airway(especially small airway) resist-ance.

Objective To investigate the role of NF-?B signal pathway in the stress of a rat acute colitis model. Methods Acute colitis were induced by 6% intracolonic acetic acid lavation in rats; the spinal I-?B levels were measured by Western blot at L5-S1 and C2-4 levels; the spinal COX-2 mRNA levels were measured by RT-PCR at the same segments; the expressions of spinal COX-2 were also measured by immunohistochemistry. Results There were obvious regional inflammatory responses after intracolonic acetic acid lavation in rats; the extent of inflammation was gradually aggravated with time.The expressions of spinal I-?B at L5-S1 level significantly increased after 0. 5 h in acute colitis group. Expressions of experimental group were significantly higher than that of sham group at half an hour(P

A questionnaire survey was conducted in 114 medical students of 4th year in eight-year program before and after community clerkship of general practice.The survey showed that there were significant differences in the awareness of the function and features of community health service,the doctorpatient relationship and the difference with large hospitals before and after community clerkship (P ＜ 0.05).The willingness of students to work in the community health service was low (P ＞ 0.05).85.1％ students (97/114) thought that the community health service center had a harmonious doctor-patient relationship,65.0％ (74/114) thought that full communication between general practitioners and patients was an important factor to build a harmonious doctor-patient relationship,66.6％ (76/114) felt satisfied,and 72.8％ (83/114) gained a lot in the clerkship.The results indicate that the community clerkship of general practice is conducive for students to understand theory,knowledge of general practice.

OBJECTIVETo investigate the expression of HER2/neu, Ki-67 and TK1 protein in meningiomas in correlation with tumor grades and recurrence.

METHODSTwenty cases of each of the following types of meningiomas were selected for the study, namely: the benign non-recurrent, recurrent benign, atypical and malignant, according to the World Health Organization (WHO) histological classification of nervous system, 2007. Immunohistochemistry study for HER2/neu, Ki-67 and TK1 protein was performed. HER2/neu gene amplification was detected using FISH. Cases with HER2 protein overexpression were studied by immunohistochemistry staining. The results of the biomarker assays were also used to study the correlationship with the tumor grades and tumor recurrency.

RESULTSImmunohistochemistry showed that the positive rates of HER2 expression in non-recurrence benign group, recurrence benign group, atypical group and malignant group were 3 cases (15%), 6 cases (30%), 7 cases (35%), and 10 cases (50%), respectively (P < 0.05). A higher tumor grade was correlated with a higher rate of HER2/neu expression. The Ki-67 and TK1 labeling index (LI) in non-recurrence group were lower than those in the atypical or malignant group (P < 0.05), whereas the atypical group had lower LI than that of the malignant group (P < 0.05). Higher levels of LI of Ki-67 and TK1 were correlated with higher tumor grades and recurrence of the benign meningiomas (P < 0.05). Expression of HER2 was positively correlated with Ki-67 and TK1 (r = 0.445, P < 0.01; r = 0.501, P < 0.01, respectively), and there was a positive correlation between Ki-67 and TK1 (r = 0.450, P < 0.01) as well. HER2/neu gene copy amplification in 7 of 26 cases (26.9%) of HER2 immunopositive meningiomas. The rates of HER2/neu gene amplification were 0 in tumors with 1+ immunopositivity, 4/6 in tumor with 2+ immunopositivity and 3/4 in tumor with 3+ immunopositivity. HER2/neu gene amplification in 3+ and 2+ immunopositive cases had no statistical significance (P > 0.05). Aneuploidy of chromosome 17 existed in 9 of 26 of HER2 immunopositive meningiomas (34.6%). However, the rates of chromosome 17 aneuploidy had no significant difference among tumors with variable HER2/neu imumopositivity (P > 0.05).

CONCLUSIONSHigh levels of HER2 and Ki-67 or TK1 expression correlate with the increase of tumor grades and tumor recurrence. HER2/neu gene amplification is seen in a subset of meningiomas with the protein expression (26.9%). A combination of biomarker study including HER2/neu, Ki-67 and TK1 may be useful in predicting the biological behavior of meningiomas.
