Objective To investigate the auditory brainstem response (ABR) of newborns in the neonatal intensive care unit (NICU) after hear screening failure.Methods To test ABR of 833 healthy newborns with no perinatal diseases at the clinic,and 425 newborns born in NICU who failed the hearing screening of monaural or both-ear from March 2014 to May 2015.Results 49.6% of children′s wave V response thresholds were ≥30 dB in the NICU group and 36.1% children′s wave V response thresholds were ≥30 dB in healthy group.The hearing abnormality rate of the NICU group was significantly higher than that of the healthy group(P<0.05);The average auditory thresholds healthy of the group[(19.76±6.59)dB] was significantly lower than those of the NICU group[(41.52±20.35)dB](P<0.05);both ear latency for waves Ⅰ,Ⅲ and Ⅴ and interpeak latency for waves Ⅰ-Ⅴ in healthy group were significantly shorter than those in NICU group (P<0.05).Conclusion The hearing loss extent of the NICU group is greater than that of the healthy group.The ABR abnormality reflects auditory pathway is abnormal.

Objective To investigate the role of M3 receptor in the effect of penehyclidine hydrochloride(PHC) upregulating β-arrestin-1 expression in lipopolysaccharide(LPS)-induced human pulmonary microvascular endothelial cell(HPMVEC) injury.Methods.M3 shRNA transfected HPMVEC and normal HPMVEC cells were randomly divided into LPS group(A),LPS+pHC group(B),LPS+ M3 shRNA transfection group(C) and PHC+ LPS+ M3 shRNA transfection group(D).The cytoskeleton change was observed by laser scanning confocal.The LDH level in cellular supernate was detected.The VCAM 1 protein expression was examined by immunofluorescence chemistry.β-arrestin-1 protein expression was determined by Western blot and β-arrestin-1mRNA expression was measured by real-time PCR.Results Compared with the group A or C,F-actin cytoskeleton arrangement in the group B or D was neat,the LDH level and VCAM-1 protein expression were decreased,and β-arrestin-1 expression was increased;compared with group A or B,F-actin cytoskeleton arrangement in the group C or D was neat,the LDH level and VCAM-1 protein expression were decreased,while the β-arrestin-1 expression had no obvious change.Conclusion Silence M3 receptor is conducive to reduce LPS-induced HPMVEC injury.But the role of PHC up-regulating β-arrestin-1 expression has no necessary connection with M3 receptor.

OBJECTIVETo compare the clinical efficacy difference between encircling needling combined with physical factor therapy and simple physical factor therapy for severe pressure sore, and to explore the optimal method for severe pressure sores.

METHODSThirty-four patients with IV-grade pressure sore were randomly divided into an observation group and a control group, 17 cases in each one. Patients in the control group were treated with conventional nursing, ultrasonic wave and short-wave ultraviolet therapy; additionally, the encircling needling was applied in the observation group. All the treatment was given once a day, 5 times a week, and 4-week treatment constituted one session. Totally, two sessions of treatment were performed. Three indices, including the area of pressure sore, 24-h volume of exudates and wound-bed tissue type, were compared between the two groups before and after treatment; the clinical efficacy was evaluated in the two groups.

RESULTSAfter treatment of one session and two sessions, the area of pressure sore, 24-h volume of exudates and wound-bed tissue type were significantly reduced in the two groups (P < 0.01, P < 0.05), which was more obvious in the observation group (all P < 0.05). The total effective rate in the observation group was 76.5% (13/17) after 1 session and 94.1% (16/17) after 2 sessions, which were superior to 35.3% (6/17) after 1 session and 64.7% (11/17) after 2 sessions in the control group (both P < 0.05).

CONCLUSIONEncircling needling combined with physical factor therapy can obviously reduce the pressure sore area and 24-h volume of exudates and improve wound-bed tissue type, which is superior to simple physical factor therapy.

Objective To investigate genotypes and antibiotic resistance of Escherichia coli producing plasmid-mediated AmpC ?-lactamase in Anhui province.Methods A total of 407 clinical isolates of nonrepeated Escherichia coli were collected from different cities in Anhui province.AmpC ?-lactamase producing isolates were identified by cefoxitin three-dimensional test and antibiotic susceptibility was identified by agar dilution test.Plasmid extraction,PCR amplication of corresponding group was performed, followed by sequencing.Results The positive rate of cefoxitin three-dimensional test was 8.1% (33/407), and the prevalence of plasmid-mediated AmpC ?-lactamase was 3.0% (12/407).bla_(CMY-2) gene,bla_(DHA-1) gene and bla_(ACT-2) gene were identified by PCR amplification and confirmed by sequencing in 5 strains,4 strains and 2 strains,respectively.A new CMY genotype was identified,with its sequence revealed 97% identity to the deduced amino acid sequence with previous CMY-2.This is also the first report on ACT-2 genotype in China.The susceptibility test showed that all strains were resistant to cephamycins and piperacillin,and susceptible to imipenem.Two strains of Escherichia coli producing DHA-1 were resistant to fourth-generation cephalosporin.Conclusions CMY-2,DHA-1 and ACT-2 are the most common genotypes in plasmid-mediated AmpC ?-lactamase produced by clinical Escherichia coli isolates in Anhui province. Carbapenems could be the first choice for the treatment of infection caused by AmpC ?-lactamase producers.

OBJECTIVE:To study the effects of Xiaoruzeng capsule on the gastric acid and pepsin in rats. METHODS:Rats were randomized into a blank group (distilled water),a positive control group (3.6 mg/kg omeprazole ) and the groups of low, middle and high doses of Xiaoruzeng capsule [2.25,4.5,9.1 g(crude drug)/kg]. These groups were respectively marked as groups A,B,C,D and E,with 10 rats in each group. All the rats were given corresponding drugs,ig,for consecutive 10 d. Their suc-cus gastricus was collected 3 h after the last administration,and determined for pH value with precision pH test strip and for free acidity and total acidity by acid-base neutralization titration method. The content and activity of pepsin were determined and calculat-ed with the test kit and microplate reader. The pathological change of the stomach was observed under the electron microscope. RE-SULTS:Compared with group A,groups B,C and D had higher pH value of succus gastricus;groups C,D and E had lower free acidity;groups B,C and D had lower total acidity,group E had higher total acidity;groups B,D and E had lower activity of pep-sin;and group C had higher content of pepsin. Compared with group B,group D had lower pH value of succus gastricus;group C had lower total acidity;group E had higher acidity;and groups C,D and E had higher activity of pepsin. There was statistical sig-nificance(P<0.01 or P<0.05). Gastric mucosal erosive haemorrhage was noted in three rats in group E,and other groups demon-strated no obvious pathological change. CONCLUSIONS:Low dose of Xiaoruzeng capsule can slightly inhibit the gastric acid in rats,but will not effect the activity of pepsin.

Objective To evaluate the effects of conscious sedation analgesia during superficial bladder tumor resection for elderly patients. Methods Forty elderly patients who needed 2 μm laser resection for bladder tumors were treated with target controlled infusion (TCI) remifentanil and propofol. The initial target concentration of remifentanil was 2.5 ng/mL and that of propofol was 1 μg/mL. The target concentration of those two agents was adjusted until loss of painfulness to the operative stimulus. The MAP, HR, SpO2, RR and PetCO2, BIS and scores by OAA/S were compared between pre-and post-surgery at different time points (time before anesthesia, T0; time before analgesia, T1; time when the resection began, T2; 5 minutes after the resection began, T3;10 minutes after the resection began, T4; 15 minutes after the resection began, T5; the end of operation, T6;5 minutes after operation). Results All patients lived through the surgery under a conscious sedation. After the anesthesia, blood pressure, heart rate and breathing rate were declined, while oxygen saturation was unchanged. Conclusion TCI with remifentanil and propofol provides better hemodynamic stability, satisfactory sedation analgesia and faster recovery of surgery.

Objective To investigate the changes of the cell cycle regulators ATM, Chk2 and p53 and cell cycle arrest in HeLa cells after cisplatin therapy. Methods The proliferation-inhibiting rates of HeLa cells induced by eisplatin of different concentrations were measured by MTT assays. The mRNA and protein expressions of ATM, Chk2 and p53 of HeLa cells with and withont cisplatin were detected by RT-PCR and Western blot, respectively. The cell cycle analysis was conducted by flow cytometric analysis. Results Cisplatin inhibited the proliferation of HeLa cells in a dose- and time-dependent manner. The mRNA and protein expressions of ATM, Chk2 and p53 were increased in HeLa cells treated with cisplatin. The cell cycle was arrested in G2/M phase in HeLa cells treated with cisplatin. Conclusion Activation of ATM, Chk2 and p53 might be critical in determining whether cells survive or undergo apoptesis. Targeting ATM, Chk2 and p53 pathway might he a promising strategy for reversing chemoresistance to clsplatin in cervical cancer.
