This article discusses the status quo of mental health,common legal and ethical problems in the diagnosis and treatment of psychological clinical practice,and also puts forward concrete contents and requests for strengthening the self- discipline and right- safeguard in the diagnosis and treatment in psychological clinical practice.

153 TMD patients were randomized to be treated by closed treatment of Kenalog(78 cases)and prednisolone(75 cases)respec-tively.Data were analyzed by SPSS 17.0.4-week-follow-up showed that Kenalog closed treatment was more effective than prednisolone(P<0.05).

Objective To investigate molecular typing and drug resistance patterns of 98 Klebsiella pneumoniae (K.pneumoniae) isolated from type 2 diabetes patients complicated with maxillofacial infection,to research the virulence and resistance mechanisms.Methods The study was a prospective study that adopted the method of continuous sampling from fixed location,from March 2010 to October 2012.The maxillofacial surgery patients diagnosed with type 2 diabetes complicated with maxillofacial infection were chosen in 7 hospitals in Zhengzhou as the research object,and a total of 431 pus sample were collected continuously,in which 98 strains K.pneumoniae were isolated and identified.The Kirby-Bauer disk diffusion test was conducted in 98 strains to determine the resistance to 19 antibacterial agents.K.pneumoniae chromosomal DNA were digested by restriction endonuclease Xba Ⅰ and analyzed by pulsed-field gel electrophoresis (PFGE).PFGE patterns of K.pneumoniae strains were analyzed using Fingerprinting software.The relationship between the molecular types and resistance phenotype was observed.The extended spectrum β-1actamase-producing K.pneumoniae were screened out by the double disc synergy test (DDST)Polymerase chain reaction (PCR) was used to detect resistant genotypes,serotype and virulence genes.The purified PCR products of resistant genes were cloned and sequenced.Hypermucoviscosity phenotype of all strains were determined by string test.Results Much severer drug-resistance for K.pneumoniae was identified and the result of extended-spectrum beta-lactamase producing rate was 57.1 ％.Ninety-eight strains were dispatched into 13 groups by PFGE.No dominant bands and specific extended-spectrum beta-lactamase DNA bands were found.The results of PCR showed that among the 56 strains of extended spectrum β-lactamase-producing K.pneumoniae,40 were positive for blaSHV (accounting for 71.4％),28 positive for blaTEM (accounting for 50.5％),21 positive for blaCTX-M (accounting tor 37.5％).The sequencing results were as follows:TEM-1,CTX-M-3 and a variety of SHV.Serotype K1,K2,K3,K5,K20,K54 and K57 and 3 kinds of virulence genes were detected,but not in strong toxicity-based.Hypermucoviscosity positive rate was 31.6％ (31/98).Conclusion Much severer drug resistance of K.pneumoniae in this study was identified and resistant mechanism was complex,in which strong toxicity serotype and virulence geues exist,which need more attention from clinical.

Objective To study the pathogenesis,diagnosis and treatment of the compression syndrome of the third common plantar digital nerves.Methods Conservative methods were at first used for all the 34 cases of this disease.Treatment methods includes:wearing shoes with soft bottom and metatarsal pad;the administration of Chinese herbs;the application of direct current iontherapy by filtering Chinese herbs and performing local injection therapy with steroid at the tenderness points.15 patients with no effect following conservative methods and other 3 recurrent cases were treated with section of deep transverse metatarsal ligament and relaxing the nerves compression.Of the 18 cases,5 had additional to excision of the neuroma.Results Of the 34 cases treated with conservative methods,19 had effective results,of which 6 cases recurred,and 15 cases had no effect.18 cases treated with operation had no recurrence.Conclusion Toe extending test and forefoot transversely compressing test provide a valuable basis for diagnosis.Conservative treatment are usually effective in earlier phase.If conservative treatment is not effective,the transverse metatarsal ligament should be sectioned,nerves should be relaxed and the neuroma must be excised.The results of operative treatment are satisfactory.

Objective To compare the concentration of 3-nitrotyrosine and tyrosine and the ratio of 3-nitrotyrosine/tyrosine in the cerebrospinal fluid (CSF) of patients with sporadic amyotrophic lateral sclerosis (SALS) and those with healthy nervous system for definiting the role of free radicals oxidative damage in pathogenesis of SALS. Methods Subjects consisted of 15 patients with SALS and 15 patients with norml nervous system who underwent lumbar anesthesia for surgery. Their CSF was analyzed by using high performance liquid chromatography (HPLC). Results The 3-nitrotyrosine concentration was higher in patients with SALS (228.52?124.30 nmol/L) than that in controls (112.86?47.10 nmol/L) (P

Objective To explore the state of the mental health and related factors of Zangzu undergraduates in inland.Methods Two inland typical universities were chosen,according to random whole-class sampling principle from different grades,and 370 Zangzu undergraduates in inland were tested with Symptom Checklist 90(SCL-90),Self-Esteem Scale(SES),Simplified Coping Style Questionnaire (SCSQ) and social support scales,and compared with norm and Hanzu undergraduates.Results The scores of the factors of compulsion,interpersonal relation sensitiveness,depression,anxiety,hostility of Zangzu undergraduates in inland in SCL-90 were higher than 2.The rate of their mental problems(the total average score was higher than 2) was 45.3％,among them the rate of mild mental problems was 42.0％,the rate of secondary mental problems was 3.3％,without undergraduates of serious mental problems.Scores of the 9 factors were higher than that of the norm,and differences were significant (P＜ 0.01).Scores of the 9 factors were higher than that of Hanzu undergraduates,and scores of somatization,compulsion,anxiety,hostility,terror were significantly higher than that of Hanzu undergraduates (P ＜0.01).Rate of their mild mental problems was significantly higher than that of Hanzu undergraduates(P＜0.01).Scores of their self-esteem and positive coping styles were lower than that of Hanzu undergraduates,and differences were significant (P =0.000).The negative coping styles and self-esteem could predict the state of mental health of Zangzu undergraduates in a great extent.Conclusion Zangzu undergraduates in inland have more mild mental problems,which are correlated with their self-esteem and coping styles.

ObjectiveTo explore the role of HSP27 in hepatic ischemia-reperfusion (IR) injury and hepatic ischemic preconditioning (IP).MethodsMale C57BL/6 mice were randomly divided into 3 groups:control group (sham operation),IR group (only hepatic IR),rHSP27 + IR group (rHSP27 injection before IR).The extent of liver injury was evaluated among these 3 groups.Murine HSP27 was silenced by short hairpin RNA and mice were subjected to IR with or without IP after interfering succeeded.Serum ALT and AST levels,hepatic histological damages and mRNA expression levels of pro-inflammatory mediators (TNF-α,IL-1β and IL-6) were measured.Results Silencing hepatic HSP27 aggravated IR injury indicated by higher concentration of serum ALT and AST (P＜0.05),reinforced by severer histological damage and more expression of pro-inflammatory mediators (P＜0.05),while injection of rHSP27 or IP ameliorated hepatic IR injury.Western-blot showed HSP27 expression was significantly higher in IP group than sham group.Silencing HSP27 largely removed the IP-induced hepatoprotection,indicated by restoration of caspase-3 induction.ConclusionHSP27 is an essential endogenous defense of liver against IR injury.Hepatic ischemic preconditioning can improve subsequent IR injury via up-regulation of HSP27,which is related to HSP27-mediated reduction of apoptosis.
