Objective To investigate the relationship between plasma D-lactate levels and prognosis in newborns with neonatal necrotizing enterocolitis (NEC).Methods One hundred and four premature infants with NEC (stase Ⅱ and Ⅲ ) and another 104 premature infants without NEC admitted into Quanzhou Children's Hospital for other diseases from January 2007 to October 2010 were selected into this case control study.The gestational age,gender and birth weight of patients in the two groups were matched.NEC patients' bloods were collected within 24 hours after NEC was confirmed and blood samples of the control group were collected at the corresponding age.Enzymelinked immunosorbent assay was used to detect the plasma D-lactate level.Receiver operating characteristic curve was used to confirm the criteria of D-lactate positive,according to which,the NEC group was divided into high D-lactate group and normal D-lactate group,and the mortality and complication rate of the two groups were compared with x2 test.And NEC group was subdivided into death group and survive group according to the prognosis of the patients,and the difference of D-lactate level between the two groups were compared with t test.Results Among the NEC group,there were 63 cases (60.6％) of stage Ⅱ and 41 (39.4％) cases of stage Ⅲ ; 88 (84.6％) survived infants and 16 (15.4％) dead infants.D-lactate level was (35.4 ± 29.1) μg /ml in stage Ⅲ NEC group,(29.5±16.2) μg/ml in stage Ⅱ NEC group and (3.7±18.4) μg/ml in control group; there were statistical differences between each other(F=5.97,P＜0.05).Receiver operating characteristic curve analysis showed that if 6 μg/ml was set as the borderline,there were 87 cases(83.7％,87/104) with high D-lactate patients in NEC group,whose neonatal critical illness scoring (NCIS) was 80.9±22.6,significantly lower than that of normal D-lactate patients ( 95.8 ± 20.5) (t =2.417,P＜ 0.05),and higher neonatal septicemia rate (48.3％,42/87) and mortality (27.6％,24/87) compared with those [(5.9％,1/17) and (5.9％,1/17)] of normal D-lactate patients(x2 =11.539 and 7.146,P＜0.05,respectively).In NEC group,compared with the survived infants,the D-lactate level [(43.2±13.5) μg/ml vs (21.9 ± 22.9) μg/ml,t =4.572,P＜0.05] and the rate of septicemia [68.8％ (11/16) vs 38.6％ (34/88),x2 =3.445,P＜0.05] were higher in dead patients,and NCIS (82.4± 29.1 vs 90.6 ± 21.3,t =2.409,P＜0.05) was lower.Conctusions The level of plasma D-lactate related to the prognosis of neonatal NEC and which might be a good indicator for its prognosis and severity.

Objective To study the activation effect of HBV RNase H protein on the transcription of cellular apoptosis susceptibility gene (CAS). Methods The promoter of DNA sequence of CAS gene was identified in GenBank by bioinformatics and amplified from HepG2 genome by PCR using sense (5′-GGTACCCGATTACATGTTGTACATGAAGG-3′) and antisence (5′-CTCGAGGCTGAGTTCCATTGCTATAG-3′) primers. As these primers contained Kpn I and Xho I recognition sites on their respective 5′-ends, the amplified DNA fragments were tested by sequencing and then subcloned into Kpn I/Xho I sites of pCAT3-Basic reporter vector by routine molecular biological methods. The reconstructed plasmid named pCAT3-CASp was identified by enzyme digestion of Kpn I/Xho I, in which the expression of chloramphenical acetyltransferase (CAT) was under the control of the promoter of CAS. The HepG2 cells were transfected by pCAT3-CASp, and then co-transfected by pCAT3-CASp and pcDNA3.1(-)-RH plasmids. At the same time, the empty pCAT3-basic and pCAT3-TXNRD1p were transfected (self-contructed by the authors) as controls. After 24h culturing, cells were collected and the expression of CAT activity was detected by ELISA according to the manufacturer′s protocol. Results The optical density of expression of CAT of pCAT3-CASp was 0.043 by ELISA, in contrast, the optical density of expression of pCAT3-Basic was 0.024. The expression of CAT in co-transfection of pCAT3-CASp and pcDNA3.1(-)-RH(0.065) was 1.5 times as higher as pCAT3-CASp plasmid (0.043), and 2.7 times as higher as pCAT3-Basic. Conclusions The CAS gene promoter identified in present study has transcription activity and HBV RNase H protein may activate the expression of CAS gene.

Objective To study the clinical features of primary biliary cirrhosis (PBC) in order to improve the clinical diagnosis. Methods Clinical data of fifty patients with PBC were retrospectively studied. The clinical features, results of laboratory tests, pathological findings of all the fifty patients were analyzed. Results forty-four patients were female (88%), and the mean age was 44.94?12.33 years at the time when definite diagnosis was made. The most frequent symptoms complained were fatigue (34/50, 68%), anorexia (24/50, 48%) and pruritus (13/50, 26%).The major signs included jaundice (32/50, 64%), splenomegaly (24/50, 48%) and liver palms (14/50, 28%). Serum alkaline phosphatase (ALP) and r glutamyl transpeptidase (r-GT) levels were markedly elevated in most patients, and the levels of ALP and GGT declined during the advanced stage. The levels of ALT and AST were elevated slightly. The total level of serum bilirubin was elevated in thirty-two patients (64%). Positive anti-mitochondrial antibody (AMA)/AMA-M2 were found in forty-one patients (82.0%). Pathological examination was done in 32 patients, it was shown that 28 patients (87.5%) were in early stage and 4 patients (12.5%) in advanced stage. Conclusion PBC occurs mainly in middle- and old aged women. The main clinical manifestations are fatigue, anorexia and pruritus. The elevated level of ALP, r-GT and positive AMA/AMA-M2 may be crucial to diagnosis of PBC.

Objective To assess the efficacy of postoperative adjuvant interferon (IFN) therapy on patients with hepatitis B virus (HBV) related hepatocellular carcinoma (HCC).Methods An electronic search for articles published from January 2000 to January 2013 was conducted to identify English language comparative studies evaluating IFN therapy on recurrence and survival after surgical treatment of HCC.Results A total of five trials consisting of 694 patients were included in the Meta-analysis.The estimated odds ratios (OR) for the 1-,2-,3-,and 5-year overall survival rates of HBV-related HCC were 3.37 (95％CI:1.18-6.27,P=0.000),2.36 (95％ CI:1.45-3.83,P=0.001),1.81 (95％ CI:1.21-2.72,P=0.004),and 1.93 (95％ CI:1.35-2.75,P=0.000),respectively.The OR for the 1-,2-,3-,and 5-year recurrence rates were 0.63 (95％ CI:0.44-0.91,P=0.014),0.84 (95％ CI:0.60-1.18,P=0.322),0.88 (95％ CI:0.63-1.22,P=0.431),and 0.78 (95％ CI:0.56-1.07,P=0.120),respectively.Conclusion This Meta-analysis shows that IFN therapy had a significant clinical effect in improving overall survival rates but not in decreasing recurrence rates of HBV infected HCC patients postoperatively.

Objective:To develop a new method of manufacture of presurgical nasal stent by computer-aided design and manufactur-ing(CAD/CAM)technique for infants with cleft palate and nasal deformity.Methods:A neonate with unilateral lip and palate cleft and nasal deformity was recruited.The nose-lip area was scanned by a 3D human body scanner and transformed into 3D digital model by the reverse engineering software.The nasal data of the normal side was mirrored to cover the deformed side and processed by the re-verse engineering software,which became the original data of the presurgical nasal stent.Nasal stent was manufactured by rapid proto-typing machine.The stent was applied for the patient to correct the nasal deformity.Results:The original data of the nose-lip area were obtained via scanning within 0.1 second,and the 3D model was reconstructed by the reverse engineering software.The nasal stent made by CAD/CAMtechnique matched perfectly with the models and fitted well when tried on the patient's face.The appearance of the deformed nose was obviously improved by the nasal stent.Conclusion:CAD/CAMtechnologies can be used in the design and manu-facture of individual nasal stent for infants with cleft palate and nasal deformity.

Objective To investigate the distribution and drug resistance of bacterial pathogens isolated from peritonsillar abscess .Methods Data on bacterial pathogens isolated from peritonsillar abscess in Wenzhou Central Hospital from January 2010 to December 2014 were retrospectively analyzed .Strains were identified with Vitek 32 identification system and the drug susceptibility test was performed with K-B method.Chi-square test for linear trend was performed to reveal the changes of distribution and drug resistance of the strains .Results A total of 2 864 bacterial strains were isolated in five years , in which 1 786 strains were Gram-negative bacilli (62.4%), and 1 078 (37.6%) strains were Gram-positive cocci. The positive rate of Gram-negative bacilli was on the rise during year 2010-2014 (χ2 =84.74, P<0.01), and the top three Gram-negative bacilli were Pseudomonas aeruginosa, Acinetobacter baumannii and Haemophilus influenzae, which accounted for 72.5%(1 295/1 786) of the total Gram-negative strains, and the positive rates of first two bacilli were on the rise (χ2 =83.75 and 24.74, P<0.01).Gram-positive cocci were mainly Staphylococcus aureus and Hemolytic streptococcus, which accounted for 83.2% ( 897/1 078) of the total Gram-positive strains.Resistance rates of Pseudomonas aeruginosa to ceftazidime, cefoperazone, piperacillin/tazobactam were on the rise (χ2 =16.17, 13.48 and 11.44, P<0.05), while resistance rates to gentamicin and amikacin were on the decline (χ2 =16.54 and 16.63, P <0.05). Resistance rates of Acinetobacter baumannii to ceftazidime, cefoperazone/sulbactam and piperacillin/tazobactam were on the rise (χ2 =12.52, 10.85 and 14.14, P<0.05).Resistance rates of Haemophilus influenzae to ampicillin were on the rise (χ2 =10.21, P<0.05), and the positive rate of β-lactamase producing strains was also on the rise (χ2 =10.38, P<0.05).Resistance rates of Staphylococcus aureus to cefazolin and methicillin were on the rise (χ2 =15.44 and 12.53, P<0.05), but no vancomycin resistant strain was found .Hemolytic streptococcus were sensitive to all commonly used antibiotics .Conclusions Peritonsillar abscess in Wenzhou Central Hospital is mainly induced by Gram-negative bacilli infection . Pseudomonas aeruginosa, Acinetobacter baumannii and Staphylococcus aureus are the top three bacterial pathogens , and are highly resistant to most antibiotics .

OBJECTIVE: To investigate the correlation between tongue body MRI measurements and the lingual region obstruction in patients with obstructive sleep apnea hypopnea syndrome (obstructive sleep apnea hypopnea syndrome, OSAHS), and the relationship of two diagnosis methods in positioning obstructive level, in order to improve the preoperative diagnostic accuracy of obstructive level in OSAHS patients . METHOD: Fifty-nine patients with OSAHS definited by the AG200 sleep apnea monitoring and obstruction plane positioning system was included. They all underwent tongue MRI scan, after three-dimensional reconstruction, the tongue body length to diameter, relative thickness, basal diameter, wide around central about wide diameter and tongue body volume were measured. The lower blocking (mainly composed of lingual region) constituent ratio P established by AG200 was correlated with tongue parameters measured by MRI. At the same time, To analysis of differences of P in patients with different degree of OSAHS. RESULT: Among these patients with OSAHS in different degree, the coefficient correlation between tongue parameters(tongue length, relative thickness, basal diameter, wide middle diameter, tongue body volume) and lower blocking constitute ratio P werer LP = 0.051,rHP = 0.069, r1 = 0.215, r2 = 0.147, rVP = 0.259, respectively. lower obstruction of form than the differences had statistical significance. The measured tongue parameters and value P(the lower blocking constituent ratio) were negatively correlated, which demonstrated that exclusing of the larynx and hypopharynx airway obstruction, the lower airway obstruction detected by AG200 was related with tongue parameters measured by MRI, and was strongestly related with the tongue body volume. CONCLUSION The volume of tongue and AG had correlation in judgement of lower blocking. In OSAHS patients the lower blocking constituent ratio varies between the defferent severity groups of the disease, the combina tion of the two method can be used to predict the obstructive plane in OSAHS patients with upper airway obstruction, and provide the basis for the individual treatment of patients with OSAHS.
