METHODS:210 AD patients were divided into donepezil group,rivastigmine group,galantamine group,Compound haishe capsule group,donepezil + Compound haishe capsule group,rivastigmine + Com-pound haishe capsule,and galantamine + Compound haishe capsule group,30 cases in each group according to visiting order. Donepezil group received Donepezil hydrochloride tablet 5 mg(<1 month)before going to bed,10 mg(≥1 month),po,qd;riv-astigmine group received Rivastigmine hydrogen tartrate capsule 1.5 mg(<1 month)before going to bed,3.0 mg(≥1 month), po,bid;galantamine group received Galantamine hydrobromide tablet 2 mg (<2 weeks),4 mg (2-4 weeks),6 mg (>4 weeks),po,bid;Compound haishe capsule received Compound haishe capsule 3 casuples,po,tid;donepezil + Compound haishe capsule group received Donepezil hydrochloride tablet 5 mg,po,qd + Compound haishe capsule 3 casuples,po,tid;galantamine+ Compound haishe capsule group received Rivastigmine hydrogen tartrate capsule 1.5 mg,po,bid + Compound haishe capsule 3 casuples,po,tid;galantamine+Compound haishe capsule group received Galantamine hydrobromide tablet 4 mg,po,bid+Com-pound haishe capsule 3 casuples, po, tid. The treatment course for all groups was 3 months. Mini-mental state examination (MMSE),AD dementia rating scale (ADAS-cog) and ability of daily life (ADL score) before and after treatment,and TESS score after treatment in all groups were observed,and the occurrence of ADR was observed. RESULTS:There was no statistical significance in MMSE, ADAS-cog and ADL score between 2 groups before treatment (P>0.05).After treatment, MMSE, ADAS-cog and ADL score in all groups were obviously improved;MMSE scores in ChEI combined with Compound haishe cap-sule groups were obviously higher than appropriate ChEI alone groups and Compound haishe capsule alone group,ADAS-cog and ADL scores were obviously lower than appropriate ChEI alone groups and Compound haishe capsule alone group;TESS scores in-cidence of adverse reactions in Compound haishe capsule alone group or combined with ChEI groups were obviously lower than ap-propriate ChEI alone groups and Compound haishe capsule group,the differences were statistically significant (P<0.05). CON-CLUSIONS:ChEI combined with Compound haishe capsule can effectively improve the mental state of AD patients,cognitive function and life activity,with higher safety.

Objective To identify the pathogenic microorganism by MALDI-TOF MS.Methods A total of 560 strains were resuscitated,which included 260 gram-positive bacteria strains,180 gram-negative bacteria strains,60 yeast-like-fungi strains and 60 enteropathogenic bacteria strains.Comparing MALDI-TOF MS with Vitek2 Compact,the discordant results were validated by 16S rDNA sequencing.Results Comparing MALDI-TOF MS with Vitek2 Compact,the coincidence rate was 94.6％ (246/260) for gram-positive bacteria,96.7％ (174/180) for gram-negative bacteria,95％ (57/60) for yeast-like-fungi,and 93.3％(56/60) for enteropathogenic bacteria Fifteen strains were validated by 16S rDNA gene sequencing.Comparing with sequencing,the coincidence rate of two methods was 66.7％ ( 10/15 ) for MALDI-TOF MS and 26.7％(4/11 ) for Vitek2 Compact,respectively.Conclusion MALDI-TOF MS shows rapid turnaround time and modest reagent costs,and it will be another effective tool for microorganism diagnosis.

Objective To evaluate the symptom improvement of anxiolytics and antidepressant to hemifacial spasm(HFS)patients with anxiety and depression. Methods A total of 60 HFS patients with anxiety and depression were enrolled for the study and divided into experimental group and control group. Experimental group were treated with escitalopram and BTX-A ,and control group only received BTX-A. SAS and SDS were used to test all the patients before and after treatment. Results Both experimental group and control group were significantly improved after BTX-A therapy. There was no different between two groups at 1 week and 1 month,respectively. At 2 weeks and 3 months,more obvious improvement was seen in experimental group. The SAS and the SDS standard average scores of experimental group were significantly decreased compared with the control group. There was statistical significance in control group after 1 month and 3 months treatment(P<0.05),and in experimental group,the differences appeared after 2-week treatment(P<0.05). Additionally,after 1 month treatment,there were statistical differences between the two groups(P<0.05),and experimental group shown a longer effective period compared with control group. Conclusion Anxiety and depression state serves as a complication of HFS ,which is positively correlated with HFS. HFS patients with anxiety and depression benefit better from escital-opram and BTX-A combination therapy than BTX-A alone.

Objective: To compare the effectiveness of less invasive surfactant administration (LISA) and intubate surfactant extubation (INSURE) on respiratory distress syndrome (RDS) among premature infant, so as to provide insights into improving treatment effects and reducing complications of RDS among premature infants. Methods: A total of 71 premature infants with RDS in Anhui Provincial Maternity and Child Health Hospital were randomly assigned into the LISA and INSURE group, and pulmonary surfactant (PS) administration was carried out by LISA and INSURE with basic support therapy and respiratory support therapy. The general information, arterial blood gas analysis before and after treatment, respiratory support time and incidence of complications were collected and compared between the two groups. Results: There were 31 cases in the LISA group, with a gestational age of (29.81±0.99) weeks and 22 male cases, and 40 cases in the INSURE group, with a gestational age of (30.02±1.13) weeks and 26 male cases. There were no significant differences in basic characteristics (including gestational age, birth weight, gender, etc.) between the two groups (all P>0.05). After administration, the level of PaO2 was lower in the LISA group than in the INSURE group [(78.35±6.55) mmHg vs. (87.68±8.21) mmHg, P<0.05], the level of PaCO2 was higher in the LISA group than in the INSURE group [(43.03±6.34) mmHg vs. (38.68±9.69) mmHg, P<0.05], and the incidence of bronchopulmonary dysplasia was lower in the LISA group than in the INSURE group (48.39% vs. 72.50%, P<0.05). Linear regression analysis showed that with the duration of LISA administration increase (2-7 min), the minimum heart rate of premature infants increased linearly (β=13, P<0.05). Conclusions Compared with INSURE, LISA administration could slowly improve ventilation oxygenation, reduce hyperventilation and incidence of bronchopulmonary dysplasia among premature infants with RDS. The incidence of slow heart rate may be reduced by appropriately prolonging the administration duration.

Insolinoma is a rare disease,but with an increased incidence in recent years.From March 2003 to October 2010,16 patients with insulinoma had been admitted to the Nanfang Hospital,and the results of imaging investigation were compared with histopathological examination after operation.All cases had typical Whipple's triad,low plasma glucose and high plasma insulin concentrations. Sixteen tumors were found in total.The detection rate of ultrasonography was 44％ (7/16),and the detection rate of enhanced computed tomography (CT)and magnetic resonance imaging (MRI) were 67％ (8/16) and 75％ (6/8) respectively.The detection rate reached 88％ by combination of CT and MRI.Two patients had no abnormal findings in ultrasonography,CT and MRI,while positive results were found in the arterial stimulation procedure with venous sampiing (ASVS) in both patients.CT or MRI is the preferred approach for localization diagnosis of insulinoma. The ASVS achieves a distinct advantage in localization of insulinoma.

Objective To investigate the changes of PTX3,NT -ProBNP level and the correlation between them and the prognosis of the patients with AMI combined T2DM.Methods 143 patients with primary AMI were enrolled,of which 63 patients with type 2 diabetes (observation group)and 80 patients with no diabetes (control group).Plasma PTX3 values were measured with ELISA method and NT -ProBNP was detected by the electrochemi luminescence method.All patients were observed for the occurrence of MACE during hospitalization and 12 months after discharge.The correlation between PTX3,NT -ProBNP concentration and occurrence of MACE in observation group were analyzed.Results The PTX3,NT -ProBNP concentration[(8.95 ±5.06)ng/mL,(1 609 ±1 049)pg/mL]in the observation group were significantly higher than those in the control group[(7.03 ±3.70)ng/mL,(1 198 ± 809)pg/mL](P =0.010,P =0.009);The number(n =26)of patients with occurrence of MACE in the observation group was significantly higher than 15 cases in the control group(P =0.003).In the observation group,the PTX3, NT -ProBNP concentration[(10.98 ±5.45)ng/mL,(2 007 ±1 097)ng/mL]in patients with MACE were signifi-cantly higher than those in patients without MACE[(7.53 ±4.28)ng/mL,(1330 ±930)ng/mL](P =0.007,P =0.010),and in MACE group,the PTX3,NT -ProBNP concentration[(13.88 ±6.84)ng/mL,(2 596 ±1 333)ng/mL] in patients with death weresignificantly higher than those in patients without death[(9.18 ±3.52)ng/mL,(1 639 ± 751)ng/mL](P =0.029,P =0.023).Conclusion More strong chronic inflammatory reaction and serious myocar-dial injury might occur in the patients with AMI combined and T2DM,and those patients would have poorer prognosis. The combined detection of PTX3,NT -ProBNP has an important significance in evaluating of the degree of myocardial damage and the prognosis of the patients with AMI combined T2DM.
