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 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 provide reference for clinical rational use of anti-epileptic drugs. METHODS:In this retrospective review,serum concentrations of anti-epileptic drugs in a total of 499 patients who were treated with anti-epileptic drugs (such as sodium phenytoin,phenobarbital,carbamazepine and valproate sodium) in our hospital during 2007 were analyzed statistically. RESULTS:Among the patients receiving one kind of anti-epileptic drugs,206 cases (61.49%) were within normal range in blood concentration versus only 45 cases (44.12%) for patients receiving combined drugs. In addition,the above four drugs (sodium phenytoin,phenobarbital,carbamazepine and valproate sodium) were detected in 59.68% of the patients who took Chinese medicines,and among them,3.23% were within normal range in blood concentration. CONCLUSION:Monitoring on serum concentrations of anti-epileptic drugs is conducive to a better control of therapeutic concentration. It is advisable to refrain from using anti-epileptic drugs in combination but to adopt individualized administration. In addition,great importance should be attached to whether there are chemo-synthetic drug components contained in Chinese medicine.

Objective To explore the effect of ischemia-reperfusion injury on the retinal functions of rats. Methods Seventy Wistar rats were selected, 20 of which were selected randomly and divided into two groups (control group and single-irrigated group). The rats were anesthetized and their anterior chambers of the right eyes were cannulated with a 7-gauge needle connected to a reservoir containing ringers balanced salt solution, which was maintained at the same level of the eye for 1 hour. After that, ERG was recorded in both eyes of all rats. All the left rats were divided randomly into 10 groups and they were treated as the single-irrigated group. Retinal ischemia was induced by raising the reservoir to a height of 150 mm Hg. One hour later except the single ischemia group, all of the groups resumed perfusion after 3,6,12,and 24 hours and 3,5,7,14,and 21 days separately. ERG was recorded in both eyes of all rats. Results There was no difference in the results of ERG between left and right eyes in either the control group or the single-irrigated group. All the waves of ERG vanished in the single-ischemia group after 1 hour. In the ischemia-reperfusion groups, the waves of ERG partly recovered and the amplitude reduced persistently and progressively. Conclusion Ischemia-reperfusion injury may affect the function of the retina persistently and progressively.

MicroRNAs (miRNA) are a newly discovered class of endogenous,evolutionarily conserved small noncoding RNAs involved in posttranscriptional gene regulation. Functionally speaking,miRNAs act as key regulators in a wide variety of biological processes,including cell proliferation,cell differentiation,apoptosis,metabolism,developmental timing,signal transduction and tumor. Recent publications have provided compelling evidence that a range of miRNAs are involved in the regulation of immunity,including the innate immunity,proliferation of monocytes and neutrophils,the development and differentiation of B and T cells,infection and immunity,and the release of inflammatory mediators. In this review,we examine what is presently known of the function and mechanism of these miRNAs in the regulation of the innate and acquired immune response.

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.

Objective To evaluate renal plication and nephropexy in the treatment of giant hydronephrosis. Methods 18 patients with giant hydronephrosis underwent relief of the obstruction as well as renal plication and nephropexy were reviewed. Results The patients have been followed up for three months to three years and their hydronephrosis improved a lot.The effected kidney showed some recovery of function on excretory urography. Conclusions Renal plication and nephropexy can promote recovery of renal anatomy and function after the relief of obstruction.
