Probiotics are a class of colonization in the intestine to maintain a balanced intestinal flora and stimulate the mucosal immune tissue,have a major impact on the intestinal mucosal immune beneficial microbial communities.Neonatal development due to their own reasons,have low immune function,intestinal function is not sound,fewer bacterial species and so on.In this paper,probiotics on neonatal intestinal immune regulation,probiotics and neonatal necrotizing enterocolitis,feeding intolerance in premature children,newborn diarrhea,neonatal jaundice,allergic diseases,the safety of probiotics will be reviewed,including the clinical application and research progress of probiotics in neonates.Designed to enable the general pediatrician a better understanding and application of probiotics,so that such drugs more rational clinical application.

Objective To detect nuclear DNA degradation of bone marrows and brains in rat cadavers at different temperatures,and develop a new parameter for estimating early postmortem interval(PMI).Methods The brain and bone marrow were taken out for every 4h,during 0~40h after death at 10℃ and 20℃,respectively.And the single cell gel electrophoresis(SCGE) was carried out to detect the nuclear DNA degradation.Linear regression analysis was used to assay the relationship of the comet parameter HeadDNA%,Tail Length(TL) and Olive TailMoment(TM) with PMI.Results Different decline degrees of comet HeadDNA% were found in both brain cells and bone marrow cells after death,the decline of HeadDNA% in brain cells at 20℃ was faster.Compared with degradation in marrow cells,the linear relation between degradation of brain cells and PMI was better.Conclusion with that of comet parameters TL and TM,the perfect linear relationship between HeadDNA% and PMI was also observed.Conclusion Brain tissues are more suitable for PMI estimation by detecting degradation of DNA with SCGE.The HeadDNA% is more valuable for PMI estimation than TL and TM.

OBJECTIVE To explore the reasons of high wet package rate of the rent surgical instrument and to look for improvement method.METHODS A total of 2872 packages of hospitals in Chongqing city were investigated during the last two years.RESULTS Among 2872 rent surgical instrument packages,1064 packages were found to be damp(37.05%).CONCLUSIONS Unstandardized and too large packaging are the main reasons.After elimination of above two reasons,the damp rate will be decreased.

Objective To evaluate the clinic efficacy of sufentanil and remifentanil by target- controlled infusion (TCI) combined with propofol in patients undergoing endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).Methods Sixty patients,ASA Ⅰ ～ Ⅱ,undergoing elective EBUS-TBNA were randomly divided into group S ( sufentanil group),group R (remifentanil group) and group SR (sufentanil + remifentanil group),each group were twenty patients.The anesthesia of all groups is propofol intravenous anesthesia with 2％ lidocaine topical anesthesia,to controll BIS between 50 and 60 during surgery.Heart rate(HR),mean arterial pressure(MAP) pulse oxygen saturation( SpO2 ) and respiratory rate (RR) were recorded and compared 5mins after entering room(T0),30mins after the beginning of surgery(T1 ) and after surgery(T3).Arterial blood gas and the times of cough during surgery were also recorded and compared in all groups.The use of propofol and lidocaine,the wake-up time,satisfaction with anesthesia and adverse reactions in 6 hrs after surgery were also obtained.Results ( 1 ) RR decreased distinctly in group R and PaCO2 increased distinctly in group S and group R compared with that of group SR (P ＜0.05) during surgery.(2)The times of cough and the wake-up time lessened distinctly in group R and group SR compared with that of group S ( P ＜0.05 ).(3) The use of propofol and lidocaine,satisfaction with anesthesia and adverse reactions in 6 hrs after surgery were similar in all groups ( P ＞ 0.05 ).Conclusion Sufentanil compounded remifentanil by TCI combined with propofol is a safe and feasible anesthesia option for EBUS-TBNA,which provides better efficacy,high satisfaction and less side effects compared with using alone of sufentanil and remifentanil respectively.

Objective To assess the value of combined detection of enterovirus nucleic acid and antibody in early etiological diagnosis for hand-foot-and-mouth disease ( HFMD).Methods A case-control study was conducted.A total of 1 066 cases of children clinically diagnosed with HFMD from Hangzhou Children′s Hospital were involved into the research group from January to June 2014, consisting of 401 common cases and 665 severe cases; Throat swabs and serum samples from these children underwent combined detection for EV71/CA16/EV of enterovirus nucleic acid by fluorescence quantitative RT-PCR and for EV71/CA16-IgM by ELISA.All data were analyzed with SPSS 16.0.Results The total positive rate of enterovirus nucleic acid EV71/CA16/EV by fluorescence quantitative RT-PCR in the 1 066 cases of children clinically diagnosed with HFMD was 75.52%( 805/1 066 ) ( 95%CI: 72.80%-78.05%).But the total positive rate of combined detection was 91.46%( 975/1 066 ) ( 95%CI:89%.58-93.04%).The total positive rate of combined detection is higher than that of RT-PCR test(χ2 =98.338,P=0.000).The positive rate of EV71 type of combined detection was 64.63%(689/1 066)(95%CI:61.67%-67.49%),which is 15.38%higher than that of RT-PCR test 49.25%(525/1 066)(95%CI:46.21%-52.29%)(χ2 =51.453, P=0.000).In 665 severe cases of HFMD, the total positive rate of combined detection was 96.69%(643/665)(95%CI:94.95%-97.87%), which is higher than that of RT-PCR test 79.25%(527/665)(95%CI:75.92%-82.22%)(χ2 =95.607, P =0.000).In the severe cases, the positive rate of EV71 type of combined detection was 87.52%( 582/665 ) ( 95%CI:84.71%-89.89%) , which is 18.95% higher than that of RT-PCR test 68.57%(456/665) (95%CI:64.87%-72.06%) (χ2 =69.665, P=0.000).In the fatal cases, the positive rate of EV71 type of combined detection was 95.92%(94/98) (95%CI:89.28%-98.68%).Conclusions The combined detection of enterovirus nucleic acid and specific IgM antibody can significantly increase the positive rate of HFMD, especially for severe cases.The combine detection increases both the total positive rate and EV71 positive rate.Thus it has a high potential for becoming a new guidelines for laboratory diagnosis of HFMD.

Objective To detect mucin(MUC1,MUC2,MUC5AC) expressions in endoscopic ultrasound guided fine needle aspiration(EUS-FNA) specimens of the pancreatic neoplasms lesions and evaluate their diagnostic value.Methods The expression profile of MUC1,MUC2,MUC5AC from 54 EUS-FNA samples of pancreatic occupying lesions were examined by immunohistochemistry with mono- clonal antibodies.The results were correlated to the eytohistologic and clinical diagnosis of pancreatic cancer.Results Thirty-eight of the 54 patients had pancreatic cancer,6 patients had benign tumor,10 patients had chronic pancreatitis.The sensitivites of cytology and histology in diagnosing pancreatic cancer were 31.6%and 47.4%,respectively.The prevalence of MUC1,MUC2 and MUC5AC expres- sion in EUS-FNA samples of pancreatic cancer were 81.6%(31/38),10.5%(4/38),84.2%(32/38), respectively,and those in benign pancreatic neoplasms were 25%(4/16),31.3%(5/16),43.8%(7/16),respectively.There was statistically significance in MUCland MUCSAC expression between the two groups(P

OBJECTIVE To analyze situation of clearence of rust in the surgical operation apparatus.METHODS 300 surgical operation apparatus were choosed,divided into the A,B,C groups.For group A,soak method was taken to clear the rust,group B with soak and hand scrub in method,group C with soak.hand scrub and lubricant method.RESULTS The method for group C was most effective.The qualified rate and re-rust rate were 99.0% and 2.0%,respectively.CONCLUSIONS Clearence is a better method for operation apparatus maintanance,but daily cleaness is also important to avoid rusting.

OBJECTIVE To analyze the cost performance of small packs of surgical instruments and to look for their optimizing sterilization schemes.METHODS 720 sample from total surgical instruments were sefested,pressuresteam sterilization ethylene Oxide and hydrogen peroxide plasma sferilization were pexformal and compared.Statistics and analyzing finally under the condition of each kind puts The sterilization effect,cost and the period were analyzed.RESULTS All three methods call guarantee the sterilization effect,but the cost of EO and plasma were more than those of pressuresteam method(452% and 960%).CONCLUSIONS Pressuresteam sterilization show advantages in small packing instruments.
