Objective To discuss clinical effects of early (<48 hours after injury) fraeture exter-nal fixation in treatment of severe traumatic brain injury (TBI) combined with extremity fracture. Meth-ods The study involved patients with no statistical difference in aspects of age, sex, GCS, fracture ,distri-bution and general condition. According to different treatment methods at early stage (<48 hours), the pa-tients with TBI were divided into Group A (early extremity fracture external fixation) and Group B (early extremity fracture traction or cast immobilization). A comparative observation was done on complications in-cluding bedsore, pneumonia and deep venous thrombosis and on duration in ICU, hospitalization, time for fracture healing and mortality in two groups. Results Incidence rate of bedsore, pneumonia, deep ve-nous thrombosis and mortality in Group A was lower than that in Group B (P<0.05), and Group A had shorter time for ICU, hospitalization and fracture healing (P < 0.05). Conclusion For patients with se-vere TBI combined with extremity fracture, early fracture external fixation is more effective to reduce com-plications, shorten the recovery time and reduce mortality, compared with conservative methods.

Objective To investigate the outcomes of unselected peripheral T cell lymphoma (PTCL) patients treated with in-tensive first-line chemotherapy with high-dose therapy followed by autologous stem cell transplantation (ASCT).Methods Here a nonrandom study was reported for 23 PTCL patients treated with first-line intensive chemotherapy followed by autologous stem cell trans-plantation and 23 PTCL patients treated with conventional chemotherapy during January in 2000 to 2011 .All patients had received E-CHOP for 6~8 cycles, and autologous stem cell transplantation group was administrated with intensive chemotherapy followed by ASCT after complete remission or partial remission .Results There was no statistically significant difference in short-term therapeutic effect between two groups( P >0.05), but the 5-year overall survival(OS) of autologous stem cell transplantation group( 58%) was higher than conventional chemotherapy group , as well as 5-year disease-free survival time (DFS) (45%in autologous stem cell transplanta-tion group, and 21%in conventional chemotherapy group ) with both statistical significance ( P <0.05).Only the incidence of Ⅳ° myelosuppression in autologous stem cell transplantation group ( 100%) was higher than that in conventional chemotherapy group ( 13%) ( P <0.01 ) .Conclusions First-line intensive chemotherapy followed by autologous stem cell transplantation for peripheral T cell lymphoma was quietly safe utility , it was better than conventional chemotherapy which would be considered as first -line method.

Objective:To explore the effect of virtual reality (VR)-based baduanjin exercise on the cognition, physical functioning and life quality of elderly persons with mild cognitive impairment (MCI).Methods:Fifty-seven mildly impaired elderly persons were randomly divided into an observation group ( n=29) and a control group ( n=28). Both groups were given routine care and health education in their nursing homes, while the observation group additionally performed 50 minutes of VR baduanjin exercise three times a week for 24 weeks. Both groups were assessed using the Montreal cognitive assessment (MoCA), the Rivermead behavioural memory test (second edition) (RBMT-Ⅱ), a digit-symbol substitution test (DSST) and the Trail Making Test (TMT). The short physical performance battery (SPPB) and Alzheimer′s disease quality of life (QOL-AD) instrument were also administered before and after the 24-week intervention. Results:After the intervention the average MoCA, RBMT-Ⅱ, DSST, TMT-A, SPPB and QOL-AD results of the observation group were all significantly better than before the intervention and better than the control group′s averages. The observation group also performed better on the 5 times sit-to-stand test, the tandem standing test and a walking speed test after the intervention.Conclusions:VR-based baduanjin practice can effectively improve the cognition and physical functioning of mildly impaired elderly persons, as well as improving their quality of life.

Bipolar affective disorder refers to a category of mood disorders characterized clinically by the presence of both manic or hypomanic episodes and depressive episodes.Lithium stands out as the primary pharmacological intervention for managing bipolar affective disorder.However,its therapeutic dosage closely approaches toxic levels.Toxic symptoms appear when the blood lithium concentration surpasses 1.4 mmol/L,typically giving rise to gastrointestinal and central nervous system reactions.Cardiac toxicity is rare but serious in cases of lithium poisoning.The study reports a case of a patient with bipolar affective disorder who reached a blood lithium concentration of 6.08 mmol/L after the patient took lithium carbonate sustained-release tablets beyond the prescribed dosage daily and concurrently using other mood stabilizers.This resulted in symptoms such as arrhythmia,shock,impaired consciousness,and coarse tremors.Following symptomatic supportive treatment,including blood dialysis,the patient's physical symptoms gradually improved.It is necessary for clinicians to strengthen the prevention and recognition of lithium poisoning.

OBJECTIVES: To explore the metabolite characteristics in medial prefrontal cortex (mPFC) by METHODS: A total of 46 patients with the first-episode schizophrenia (FES), 49 people with clinical high risk (CHR), 61 people with genetic high risk (GHR), and 58 healthy controls (HC) were enrolled. The levels of N-acetylaspartylglutamate+N-acetylaspartate (tNAA), choline-containing compounds (Cho) and myo-inositol (MI), glutamate+glutamine (Glx) in medial prefrontal cortex were measured by single-voxel RESULTS: There were significant differences in Glx, tNAA, and MI concentrations among 4 groups (all CONCLUSIONS The decreased levels of MI and Glx in the FES patients suggest that there may be glial functional damage and glutamatergic transmitter dysfunction in the early stage of the disease. The compensatory increase of metabolites may be a protective factor for schizophrenia in the genetic individuals.
