ObjectiveTo investigate the effects of moxibustion on the expression of tryptophan hydroxylase 2(TPH2) mRNA in median raphe nuclei and the activity of monoamine oxidase (MAO) in serum and cortex in depression model rats and to explore its mechanism.MethodsFemale SD rats were randomly divided into control group(n=6),model group(n=7) and moxibustion group(n=7).The rat depression model was induced by giving isolation-housing in combination with chronic unexpected mild stress(CUMS) for 21 days.The hemi-quantitative reverse transcription-polymerase chain reaction(RT-PCR) was employed to detect the relative expression of TPH2 mRNA,colorimetry was used to test the activity of MAO.ResultsThe expression of TPH2 mRNA in median raphe nuclei in rats of the moxibustion group was higher than that in the model group( relative dentisty value:(0.3759 ± 0.0272)vs(0.2573 ± 0.0581 ),P ＜ 0.05 ).The activity of MAO in serum and cortex was reduced in rats of the moxibustion group( ( 1.919 ± 1.243 ) U/ml,( 1292.048 ± 90.072 ) U/mg protein,respectively) compared with that in the model group ( (4.117 ± 2.727 ) U/ml,( 1441.345 ± 117.050 ) U/mg protein,respectively).ConclusionMoxibustion has the effects of improving depression,increasing the expression of TPH2 mRNA in median raphe nuclei and reducing the activity of MAO in serum and cortex might be one of its mechanisms.

The reproductive toxicity of environmental estrogens(EEs)has become an extensively studied subject in environmental science and reproductive medicine nowadays.Many epidemiology data and experimental evidences indicated that EEs may significantly cause the disorders of male sex differentiation such as microphallus,hypospadia,cryptorchidism and masculinization behavior disorder and so on.The mechanism includes estrogenic activity,anti-androgenic activity as well as other feedback regulation and signal transmission which influence hormones metabolism.

Objective To investigate the effects of children's mentality on mental symptoms during recovery period of ketamine anesthesia. Methods According to the mentality, forty-five children undergoing smalminor surgery were assigned into active group, stable group and fretful group with 15 cases each. Child was anaesthetized by ketamine alone. RP, BP, HR and SpO_2 were recorded at the end of operation, 5,10 and 30 min after operation. Meanwhile the expression, feeling, behavior, talking and activity were observed. Results RR, BP, HR in active group and fretful group were significantly higher than those in stable group. There was a significant difference in the expression, feeling, behavior, talking and activity among three groups. Conclusion Children's mentality has a significant effect on mental symptoms and hemodynamics during recovery period of ketamine anesthesia.

Nonaqueous capillary electrophoresis-chemiluminescence (NACE) method was developed for the determination of five phenolic environmental estrogens including bisphenol A (BPA),4-nonylphenol(4-NP) ,4-tert-octylphenol(4-tOP),4-tert-butylphenol(4-tBP) and tetrabromobisphenol A(TBBPA) in food packaging material. Target compounds in soaking solution of food packaging material samples were separated by NACE-CL after derivatization with 4-(4,5-diphenyl-lH-imidazol-2-yl) benzoyl chloride ( DIB-Cl) ,reacted with per-oxyoxalate chemiluminescence system,and then detected through magnifying light signal with photomultiplier. With 17β-E_2 as internal standard,qualitative and quantitative analysis of the target compounds were performed by relative migration time and the ratio of relative chemiluminescence intensity,respectively. Several influence factors on separation with NACE,such as the composition and proportion of organic solvent,the concentration of electrolyte,temperature surrounding of the capillary,the concentration of acetic acid and work voltage,were investigated. And the peroxyoxalate chemiluminescence system was optimized. Under these conditions,4-tBP,BPA,4-OP,4-NP and TBBPA were all separated and showed good linearities in the ranges of 0.0095-3.0 mg/L,0.0087-3.0 mg/L,0.0085 -3.0 mg/L,0.011 -3.0 mg/L,0.009-3.0 mg/L,respectively,with correlation coefficients over 0. 9947. The RSDs of relative migration time and relative chemiluminescence intensity ratio were 0.9% -3.0% and 6.5% - 8.6%. Recoveries for the spiked samples ranged from 86.7% to 98. 8%. Five common food packaging material samples were analyzed. The proposed method is simple and sensitive for the quantitative determination of phenolic environmental estrogens in food packaging material samples.

A case of methamphetamine-related cerebral infarction was reported and the relevant databases of CBMdisc and Medline were searched.Among 14 cases of ischemic stroke , the ratio of male:female was 9∶5 and the age range 19-45 years.There were anterior circulation lesions ( n=13,92.8%) and 10 of them (71.3%) had cerebral vascular occlusion or stenosis.And the predominant manifestation was hemiplegia (85.7%);among 34 cases of hemorrhagic stroke ,the ratio of male: female was 12∶5 and the age range 16-60 years.And 28 cases (82%) were≤45 years.Cerebral hemorrhage was the most common (85%).The major manifestations were headache ( n =26, 76%) and disturbance of consciousness (n=21,62%).The methamphetamine-related stroke occurs frequently in young males.And ischemic stroke tends to involve anterior circulation and cause hemiplegia.Yet hemorrhagic stroke has extensive attack sites and headache and disturbance of consciousness are quite common.

Objective To investigate prevalence of resistance genes for β-lactams in clinically isolated multidrug-resistant Acinetobacter baumannii (MDRAB)in a hospital.Methods 22 clinically isolated MDRAB strains were performed antimicrobial susceptibility testing,resistance genes forβ-lactams (TEM,SHV,CTX-M,PER,DHA, IMP ,VIM ,SIM,OXA-23,OXA-24,and OXA-58)in these strains were detected with polymerase chain reaction. Results The resistant rates of 22 isolates of MDRAB to ceftazidime,cefotaxime,cefepime,gentamycin,amikacin, ciprofloxacin,and compound sulfamethoxazole were all 100.00%;to imipenem,meropenem,and cefoperazone/sul-bactam were 50.00%,40.91 %,and 31 .82% respectively,intermediated rates were 31 .82%,36.36%,and 31 .82% respectively.The carriage rates of OXA-23,TEM,IMP ,and PER were 100.00% (n =22),72.73 %(n=16),54.55% (n = 12),and 18.18% (n =4)respectively.Detection results of SHV,CTX-M,DHA,VIM , SIM,OXA-24,and OXA-58 were all negative.Conclusion Carriage of IMP ,TEM,PER,and OXA-23 resistance genes are the major resistance mechanisms of MDRAB to β-lactamase antimicrobial agents in this hospital.

Objective:To explore the utility of psychiatric service of clients having online counseling for anxiety or depression. Methods:The anxiety group was consisted of clients (n=107) who were positive in the Self-rating Anxiety Scale (SAS) online, similarly the depression group was consisted of clients (n=102) with positive results in Self-rating Depression Scale (SDS) online screening. Both groups were investigated with the questionnaires include issues related to the clinical features, diagnostic categories and treatment vs professional advice on clients. Results:In the anxiety group (male 69/female 38), the average age was 28+8, 88(82.2%) with more than 15 years education. In the depression group (male 57 vs. female 45), the average age was 29+8, 81(79.4%) with more than 15 years education. None was illiterate. For the age, sex, education and occupation, there was no significant difference between the two groups. 81(79.4%) clients in the anxiety group and 89(87.2%) clients in the depression group were advised to visit psychiatrists or psychologists. A few were advised to counseling online only and there was no significant difference between the two groups. The main diagnoses were mood disorders, neurosis and psychogenic disorders. Actually, 29(27.1%) in the anxiety group were treated with anxiolitics, 31(30.2%) in the depression group were treated with antidepressants at local clinics. Conclusion:Most of the clients should visit psychiatrists or psychologists, and a few may have their psychological counseling online only. Health education and psychological counseling online may be helpful to improve the rate of diagnosis and treatment of mental disorders in local clinics.
