Chinese Journal of Behavioral Medicine and Brain Science 2015;24(5):477-480
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.

Proteolytic cleavage is one of the post-translational modifications and plays important roles in many biological processes, such as apoptosis and tumor cell metastasis. The identification of the cleavage events can improve our understanding of their biological functions in these processes. Although proteomic approaches using N-terminal labeling have resulted in the discovery of many proteolytic cleavages, this strategy has its own inherent drawbacks. Labeling of protein C-termini is an alternative approach. Here, we optimized the labeling procedure in the profiling protein C-termini by enzymatic labeling (ProC-TEL) and improved the labeling efficiency for the positive isolation of protein C-terminal peptides and mass spectrometric identification. We applied this approach to a complex protein mixture from Escherichia coli and identified many C-terminal peptides and internal cleaved peptides from more than 120 proteins. From the identified cleavages, we found several previously known internal proteolytic cleavage sites and many novel ones which may play roles in regulating normal biological processes. This work provides a potential new way, complementary to the N-terminomics, for the identification of proteolytic cleavages in complex biological systems.

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.

Objective To investigate the protective effect of sevoflurane on acute intracranial hemorrhage craniotomy patients. Methods 60 acute intracranial hemorrhage craniotomy surgery patients were randomly divid?ed into control and experimental group of 30 patients under general anesthesia to have craniotomy. The patients in control group was operated by propofol and remifentanil as a inhalation anesthesia ,while patients in experimental group received sevoflurane ,propofol and remifentanil as a mixed anesthesia. Then intracranial pressure ,serum C?reactive protein(CRP),serum S?100β,NSE,IL?6 and TNF?α levels of different time points were deternmined. Results Serum CRP in experimental group were significantly decreased than the control group(P<0.05)1 d af?ter operation. T0~T3 levels of serum S?100β,NSE,IL?6 and TNF?α in two groups were both increased(P <0.05),and the experimental group was significantly lower than the control group(P < 0.05). The intracranial pressure of control group was significantly higher than the experimental group(P < 0.05). Conclusion Sevoflu?rane has a brain protective role in inhibiting acute inflammation in intracranial hemorrhage craniotomy patients.

Objective To explore the clinical features of meningeal carcinomatosis (MC). Methods The clinical data of 3 male patients with MC, administered to the authors' hospital within one-year period, were retrospectively analyzed. The pathological mechanism, clinical manifestations, diagnosis, treatment and the prognosis were summarized and relevant literature was reviewed. Results All the three patients presented neurological symptoms at the onset. Case 1, 52-year-old having a history of radical resection for gastric cancer 3 years ago, suffered from headache for 2 months without apparent digestive symptoms. Case 2, 71-year-old, presented diplopia for 2 months. Case 3, 46-year-old, complained diplopia for 3 months, followed by left hip pain and urinary retentions. For case 1, examinations after admission suggested no signs of local recurrence or systemic metastasi. For case 2 and 3, lung tumors were detected and then pulmonary carcinoma was diagnosed. Cerebrospinal fluid (CSF) of the three patients showed similar changes, including mild increase of protein, decrease of glucose and chlorides. Carcinous cells (heterocyst, signet-ring cell and large round heterocyst) were found and cells with positive tumor markers were found in the CSF of all the three patients. MRI also showed specific enhancement on meninges. All these patients, died on day 7, 47 and 24 respectively, after the diagnosis was established. Conclusions Neurological symptoms might be the earliest or the exclusive clinical features of meningeal carcinoma metastasis. A detailed neurological and oncological examination is necessary for the patients with progressive neurological lesions without obvious precipitating cause.

[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.
