Objective To study on postpartum obsessive compulsive disorder at home and abroad,and to provide new idea of diagnosis,evaluation and treatment on postpartum obsessive compulsive disorder.Method A search using Medline,Embase,EBSCO,Cochrane Library,Web of Science (ISI),Pubmed databases and Google Scholar was carried out using the key words:obsessive compulsive disorder (and derivatives),perinatal,pregnancy,postnatal,postpartum,mothers (and derivatives),anxiety disorders and subtypes. These articles and their references were reviewed.Results Twenty-seven papers were incorporated,but no Chinese paper.The life prevalence of postpartum OCD was 2.3％-11.0％.The most common obsessions were aggressive,contamination and miscellaneous,and compulsion for washing/cleaning and checking.Cognitive behavioural therapy and SSRIs have been suggested as a fist-line treatment of postpartum OCD.Conclusion OCD is more prevalent in the postpartum period.The evidence that OCD in the postpartum period presents a distinctive clinical picture with specific symptomatology and course is more compelling.Collaborative,international,prospective studies that take into account the methodological and definitional issues raised in this review are necessary to provide clarification.

The paper covered the selection of clinical trial diseases in the clinical pathway experiment in the hospital in the recent two years.It also introduced such management measures as making clinical pathway texts,the rate of cases into clinical pathways,emphasis of variation management,and enhanced clinical pathway data analysis.A comparison between the groups before and after clinical pathway management,found that the clinical pathway can reduce the average days of stay and total patient costs by 3.4 days and 1519 yuan respectively.Both patients and hospitals benefit from clinical pathways.The paper also advocates continuous and dynamic management at various stages of clinical pathway management.

Neoadjuvant chemotherapy is widely used in the therapy of locally advanced breast cancer.In the recent studies,the expressions of ER,PR and C-erbB-2 in tumor may change in different scheme preand post-neoadjuvant chemotherapies for breast cancer.It is obviously changed in the neoadjuvant chemotherapy scheme of anthracyclines and paclitaxel/docetaxel,but hardly changed in anthracycline-based neoadjuvant chemotherapy scheme.

[Objective]To evaluate the efficacy of nerve transfer for reconstructing the sensory function of the sole.[Method](1)Select saphenous nerve as donor nerve for the patients with the sensory loss beneath ankle level:dissect and cut off the saphenous nerve at the medialposterior aspect at upper-middle 1/3 of the leg and divide the gastrocnemius to expose the tibial nerve at the medialposterior aspect of the tibia, cut off partly nerve fibre of the tibial nerve and then end-to-end anastomose to the proximal end of the saphenous nerve. (2) Select sural nerve as donor nerve for the patients with sensory loss of sole only:dissect and cut off the sural nerve at the posterior aspect of the lateral malleolus, expose the tibial nerve at the posterior aspect of the medial malleolus and then cut off partly nerve fibre of the tibial nerve. The sural nerve was comdicted from the subcutaneous tunel at the anterior aspect of the Achilles's tendon to the posterior aspect of the medial malleolus and end-to-end anastomose to the partial nerve fibre of the tibial nerve. [Result]All the 9 cases were followed up from 1.5 to 2 years(mean 2 l months). The SCV(sensory conduction velocity) of the tibial nerve was ranged from 36.1 to 41.2 m/s, mean 38.3 m/s and the amplitude of wave (peak-to-peak amplitude) was a range from 7 to 15.3?V, mean 11.2 ?V by orthodromic electrophysiologic techniques. All 9 cases regained the sense of pain and touch of the sole.Three cases restored their sense of two point discrimination. All the patients expressed their satisfaction with their ability of walk and no muscles atrophy of the foot. The sensory loss in donor region was oberserved only lateral part of the foot beneath the lateral malleolus (sural nerve as donor nerve) and a small part of the anterior aspect of the ankle(saphenous nerve as donor nerve).[Conclusion]Nerve transfer can reconstruct the sensory function of the sole effectively.

Objective To evaluate the reliability of colony PCR in identifying the recombinant clones selected from phage antibody libraries. Methods The digested pComb3 vector and Lc fragments, Lc library plasmid, and Fd fragments were ligated successively. The ligation product was transformed into Escherichia Coli strain XL 1-blue bacilli by electroporation and thus murine Fab phage antibody library was constructed.The transformed recombinant clones selected randomly from libraries were identified simultaneously by colony PCR, plasmid PCR and restriction enzyme digestion. The identification consistency was analyzed. The interference was excluded by control PCR using the relevant constituents as template. Results The educed library content of Lc library was 1.175?10 6 CFU and the content of Fab antibody library was 1.02?10 6 CFU. Different recombinant percentages were obtained through three different identification methods (the Lc positive recombinant percentages by colony PCR, plasmid PCR and enzyme digestion were 100%, 78% and 78%, respectively; the Fd positive recombinant percentages by three methods were 90%, 66% and 66%, respectively; the dual positive recombinant (Fd and Lc insert simultaneously) percentages by three methods were 90%, 50% and 50%, respectively). A high frequency of false-positives appeared in colony PCR identification. Nonspecific amplification of control PCR was presumably induced by some intracellular components in XL 1-blue bacilli. Conclusion The identification of the recombinant clones selected from phage antibody libraries by colony PCR remains ambiguous. So it is our assertion that the traditional identification methods such as plasmid PCR or enzyme digestion are more accurate and will less false positive results.

Objective To evaluate the efficacy and safety of oral ibuprofen for closure of patent ductus arteriosus (PDA) in preterm infants.Methods The related literatures till December 31st,2011 in Cochrane Library,PubMed,EMBASE,Ovid,Springer,China Academic Journal Full-text Database,Wanfang Database,VIP Database and China Biological Medical Literature Database were searched.The inclusion criteria were:(1) the subject of the research was preterm infants with birth weight less than 2500 g and/or gestational age less than 37 weeks; (2) randomized or semirandomized controlled trial; (3) the intervention group received oral ibuprofen,while the control group received oral placebos / intravenous indomethacin or ibuprofen; (4) the main outcome was the failure rate of PDA closure; (5) hemodynamic changes with PDA were detected by ultrasonography.Meta-analysis was performed by Review Manager 4.22 software.Results Eleven randomized controlled trials were included,among which,three were high quality reports.Meta-analysis showed lower failure rate of PDA closure in subjects received oral ibuprofen than in those received placebos orally (RR =0.22,95 ％ CI:0.14-0.35),while the number of infants required operative closure of PDA decreased significantly (RR =0.16,95％ CI:0.03-0.86).Further analysis showed the effect of oral ibuprofen was similar to intravenous indomethacin (RR =0.93,95 ％ CI:0.57-1.53),but better than intravenous ibuprofen (RR=0.42,95％CI:0.26-0.67).However,oral ibuprofen did not reduced the ratio of patients required operation compared with intravenous indomethacin or ibuprofen (RR=0.58,95％CI:0.24-1.41).The incidence of gastrointestinal hemorrhage was higher in oral ibuprofen group than that in placebos(RR=1.99,95％CI:1.13-3.50).The serum level of creatine was lower in oral ibuprofen group than in intravenous indomethacin or ibuprofen group (weighted average=-19.10,95％ CI:-25.12-12.31).Compared with intravenous indomethcin group,less necrotizing enterocolitis cases were identified in oral ibuprofen group,but no statistical significance was found (RR=0.57,95％ CI:0.30-1.09).No long-term outcome was reported in any selected literature.Conclusions Oral ibuprofen for PDA closure in preterm infants appears to be as effective as intravenous or indomethacin,and more effective than intraveous ibuproten.Oral ibuproten represents better safety.

BACKGROUND: Neurasthenia is commonly believed attributing to the complex influence of psychological, social and biological factors.OBJECTIVE: To probe the correlation of neurasthenia with personality,life events and the positive rate of serum Epstein-Barr (EB) virus.DESIGN: Case-controlled observation and prospective paired analysis.SETTING: Mental Health Institute of Second Xiangya Hospital Affiliated to Central South University.PARTICIPANTS: From May to October 2000, patients with neurasthenia,selected from the Clinical Ward of Mental Health Institute of Second Xiangya Hospital Affiliated to Central South University for medical treatment,19 males and 11 females, with mean age of (27±8), the course of disease ranged from 0.5 to 20 years with the average of 4.0 years, enrolled in this study. According to 1:1 paired principle, 30 matched volenteers, their relatives, or students of Xiangya Hospital were randomly selected as controls.Two groups were matched in age, sex and education, patients with psychological and physical disease were excluded. All participants were given written informed consent.METHODS: The level of serum EB virus IgG and IgM of two groups were determined by using ELISA methods. Blood samples were colleted before and after treatment in experimental group, while blood samples were only collected once in control group. Patients in experimental group were given routine medication and integrative psychotherapy according to their state of illness, and Eysenck personality questionnaire (EPQ) were filled in before and after treatment (including four dimensionalities: neuroticism, psychoticism, extroversion/introvision and lie, amongst which higher scores for extroversion/introvision dimensionality represented extroversion and lower dimensionality represented introvision; higher scores of neuroticism dimensionality suggested anxiety and worry. Higher scores for psychoticism suggested solitude and inadaptability to the outer environment), life events scale (including the total score for life events, positive events value and negative events value), and symptom checklist 90 (SCL-90) (consists of 10 factors scored of 0-4, representing non-symptom to severer symptom) were used to assess the clinical symptom. EPQ and SCL-90 were adopted on patients at four months after treatment for self-comparison. EPQ and life events scale were taken on healthy controls, the scores compared with that of experimental group before treatment.for EPQ, the total scores for SCL-90 and positive rate of EB virus in patients with neurasthenia before and after treatment.RESULTS: Totally 27 patients were followed up at 4 months after treatment, and 3 cases lost due to long distance from hospital, thereby 27 cases in experimental group and 30 cases in control group were remained in the roticism in neurasthenia group was significantly higher than that of control group (57.59±10.79, 40.58±8.68, t=6.536, P ＜ 0.01), scores of extroversion/introvision were obviously lower than that of control group (46.31 ±10.79, 53.50±11.28, t=3.203, P ＜ 0.01). In neurasthenic group, scores for neuroticism was obviously decreased after treatment in contrast to before events scale: The total scores and negative scores in neurasthenia group was significantly higher than that of control group (19.73±17.25, 18.93 tal scores for SCL-90: The total scores for SCL-90 was obviously declined after treatment comparing to that of before treatment in neurasthenia of EB virus IgG and IgM: The positive rate in neurasthenia group was significantly higher than that of control group (76.67% vs 26.67% );and positive rate of serum EB virus were proved to be two important pathogenic factors for neurasthenic patients.CONCLUSION: Patients with neurasthenia possess susceptible personality, such as neuroticism and introvision, and commonly experienced negative life events before illness. Moreover the positive rate of EB virus in neurasthenic patients is higher, which might be associated with the higher glucocorticoidinduced EB virus activation under stress state.

BACKGROUND: Small conductance,Ca2+-activated potassium(SK)channel,presents in various cell types and plays a crucial role in action potential profile.However,coupling and modulation of calcium and associated molecules to SK2 channel remains unclear.OBJECTIVE: To construct the recombinants of pGBAT7 and target fragments of SK2 gene,so as to observe the coupling and regulation of SK2 channel gene to calcium and other molecules.METHODS: Three pairs of primers of the target fragments of SK2 gene were designed and synthesized based on the full-length sequences of SK2.After being identified,they were individually sub-cloned into the yeast expressive plasmid pGBKT7 to construct pGBKT7-SK2 vectors.The recombinant pGBKT7-SK2 vectors were transformed into yeast AH109 by electroporation,and their activation was tested.The recombinants were extracted from yeast AH109 and verified by electrophoresis and sequencing.RESULTS AND CONCLUSION: The target fragments of SK2 gene by PCR were 411,546 and 729 bp,respectively.Three sub-clones of pGBKT7-SK2 were successfully constructed.Electrophoresis and sequencing showed that the constructed sub-clones of pGBKT7-SK2 met the expected requirements.The recombinant pGBKT7-SK2 vectors transformed into the yeast could be activated.The successful construction of the sub-clones of SK2 gene provides an important material basis for further study in the SK2 channel and function-associated molecules.
