Objective To evaluate the effects of 6-week atypical antipsychotics treatment on serum brain-derived neurotrophic factor (BDNF)level,and the correlation between BDNF level and clinical efficiency in first-episode antipsychotic-na?ve schizophrenia.Methods We recruited 39 hospitalized patients with first-episode antipsychotic-na?ve schizophrenia that met with Diagnostic and Statistical Manual of Mental Disorders—4th Edition (DSM-IV).Both Positive and Negative Syndrome Scale (PANSS)and the level of serum BDNF were measured before and after 6 weeks’treatment with atypical antipsychotics.We also studied 30 healthy controls.Serum BDNF was assayed at baseline.Results Pre-treatment BDNF level was significantly lower in the schizophrenic patients than in the controls [(6.82±2.1 5 )μg/L vs .(1 1.6 ± 3.32 )μg/L,t = 7.239,P < 0.001 ].Although BDNF level increased with treatment (t =2.349,P =0.021)in the schizophrenics,post-treatment BDNF level was still lower than in the normal controls (t =4.634,P <0.001).After 6 weeks’treatment for schizophrenia,the total score of PANSS,the scores of positive and negative symptoms,and the score of general psychopathology scale were all decreased (t =6.1 64,P < 0.001;t = 4.520,P < 0.001;t = 4.132,P < 0.001;t = 5.142,P < 0.001 ).Pre-treatment BDNF levels were directly correlated not only with the rate of decreased PANSS total score (r =0.348, P <0.05),but also with the rate of decreased negative symptoms score (r = 0.35 1,P < 0.05 ).However,pre-treatment BDNF levels were not correlated with improved positive symptoms,general psychopathology (r =0.204, 0.186,P >0.05),or duration of illness (r = - 0.058,P > 0.05 ).Changes in BDNF levels with treatment were correlated with the duration of illness (r =-0.345,P <0.05),but not with psychiatric improvement (r =0.036-0.1 74,P >0.05).Conclusion BDNF level is significantly lower in patients with first-episode antipsychotic-na?ve schizophrenia than in normal controls.It could be improved by using antipsychotics.Higher pre-treatment BDNF level may predict better response to antipsychotics.

Objective To study the features of treatment on neurochemical metabolites in prefrontal lobe and thalamus by proton magnetic resonance spectroscopy (1H-MRS) in first-episode drug-naive patients with early-onset schizophrenia (EOS).Methods Forty-two EOS (study group) met with Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-Ⅳ) were recruited.Prefrontal lobe and thalamus were evaluated by multi-voxel 1H-MRS before and 4-week after treatment with a single atypical antipsychotic.The levels of N-acetylaspartate (NAA),creatine compounds (Cr) and choline-containing compounds (Cho) were measured.The patients also received Positive and Negative Syndrome Scale (PANSS).Forty normal controls (normal control group) underwent the same 1H-MRS detection.Results Before treatment,the NAA/Cr ratios in left prefrontal lobe,right prefrontal lobe and lefi thalamus in study group were lower than those in normal control group (1.45 ± 0.26 vs 1.60 ± 0.34,t =2.251,P =0.027;1.43 ±0.26 vs 1.60 ±0.35,t =2.505,P=0.014;1.48 ±0.27 vs 1.65 ±0.35,t =2.470,P =0.016).After 4-week treatment,the NAA/Cr ratios in both left prefrontal lobe and left thalamus of study group were significantly increased compared with those before treatment (1.58 ± 0.30 vs 1.45 ± 0.26,t =2.122,P =0.037;1.62 ± 0.32 vs 1.48 ± 0.27,t =2.167,P =0.033).After 4-week treatment in study group,the total score,positive symptom score,negative symptom score and general pathologic score of PANSS,and the total score of Clinical Global Impression (CGI) were significantly lower compared with those before treatment (59.1 ± 10.2 vs 82.0 ± 13.2,t =8.896,P=0.000;15.3 ±5.1 vs 22.9 ±7.1,t =5.634,P =0.000;16.4 ±5.2 vs 21.1 ±7.8,t =3.249,P =0.002;27.4 ±7.6 vs 38.1 ± 8.8,t =5.963,P =0.000;3.6 ± 0.4 vs 4.4 ± 0.5,t =8.097,P =0.000).There was no correlation between the changes of neurochemical metabolite levels such as NAA/Cr and Cho/Cr both in prefrontal lobe and left thalamus,and the clinical symptoms changes,such as total score and every score of PANSS,the total score of CGI in study group after treatment (all P ＞ 0.05).Conclusions The ratios of NAA/Cr are decreased not only in bilateral prefrontal lobe,but also in left thalamus,and the ratios may increase both in left prefrontal lobe and left thalamus after 4 weeks' treatment with atypical antipsychotics in EOS.The treatment outcomes of NAA/Cr do not agree with the improvement of the clinical symptoms.

By repeated column chromatography, including silica gel, macroporous resin, and preparative HPLC, a new compound (1) was isolated and purified. On the basis of spectroscopic methods, the structure of 1 was elucidated as ( - ) -epiafzelechin-3, 5-di-O-beta-D-apiofuranoside (1). In the bioassay screening experiments, glucose consumption assays in IR HepG2 cells and colorimetric assay of surface GLUT4myc translocation were used to assess the effects on glucose metabolism of compound 1. Both compound 1 and its derivatives--naringin could improve glucose consumption in IR HepG2 cells and enhance GLUT4 translocation in skeletal muscle cell L6myc in a dose-dependent manner, indicating that these two compouds showed potential anti-diabetic activities in vitro.

The purpose of this study was to investigate the feasibility and clinical outcome of granulocyte colony stimulating factor (G-CSF)-mobilized haploidentical bone marrow transplantation combined with peripheral blood stem cells (hiBM+PBSCT) for therapy of leukemia. 125 leukemia patients underwent G-CSF primed haploidentical stem cell transplantation without ex-vivo T cell depletion. All haploidentical donors were injected with G-CSF at dose of 5 microg/(kg.d) for 7 days. The patients were divided into groups A and B. 29 patients in group A underwent hiBM+PBSCT at 7th and 8th days of mobilization in donors with G-CSF respectively; 96 patients in group B underwent hiBMT. All patients received the same GVHD prophylaxis regimen, the clinical outcomes were investigated. The results showed that all patients except one CML-myelofibrosis patient achieved trilineage engraftment. Engraftment median times were 15 and 19 days for neutrophil and platelet in group A respectively, while engraftment median times were 18 and 23 days for neutrophil and platelet in group B respectively. The incidences of grade II-IV aGVHD were 31.03% in group A and 12.5% in group B respectively (p<0.05). The incidences of grade III-IV aGVHD was 13.79% and 10.41% in group A and group B (p>0.05). The aGVHD-related death incidence was 3.45% and 5.21% in group A and group B (p>0.05). The incidence of grade II-IV cGVHD was 48.2% and 35.4% in group A and group B respectively (p>0.05). The incidence of extensive cGVHD was 23.3% and 15.6% in group A and group B respectively (p>0.05). The disease relapse rate was 6.8% (2/29) and 18.75% (18/96) in group A and group B respectively (p<0.05). It is concluded that the G-CSF-mobilized allogeneic haploidentical BM plus peripheral blood HSCT without T cell depletion provides a rapid and sustained engraftment without increase of severe GVHD, furthermore, the relapse rate of disease is reduced remarkably, thus this method can be used in clinic.

OBJECTIVETo investigate the protective effects of Shengui tablet (Chinese Traditional Medicine) on experimental cerebral ischemia by acute cerebral ischemia hypoxia in mice and bilateral ligation of the carotid artery in rats.

METHODSIn the acute cerebral ischemia hypoxia model, the mice were randomly divided into control group, low-, middle- and high-dose (0.16, 0.33 and 1.00 g/kg) groups of Shengui tablet, after oral treatment for 30 d, gasping time of isolated heads of mice were observed. In bilateral ligation of the carotid artery cerebral ischemia model, the rats were randomly divided into control group, model group and low-, middle-, high-dose (0.072, 0.149 and 0.450 g/kg) groups of Shengui tablet. After oral treatment for 7 d, the cerebral index, superoxide dismutase (SOD) activity and the content of malondialdehyde (MDA) were measured.

RESULTSCompared with the control model, Shengui tablet middle- and high-dose could significantly prolong gasping time of isolate heads of mice. Compared with model group, Shengui tablet low-, middle- and high-dose could significantly decrease the cerebral index and enhance SOD activity in brain tissue; only high-dose could reduce the content of MDA.

CONCLUSIONShengui tablet has significant protective effect on the cerebral ischemia.

THE causes of Cushing's syndrome are mainly divided into adrenocorticotropic hormone (ACTH) dependent and independent. ACTH dependent hypercortisolism represents excess ACTH se-creting by the pituitary or tumor outside the pituitary; and the latter one is also called as ectopic ACTH syndrome. Thorax is the most common location of causative lesions for ectopic ACTH syndrome, and the size of lesion is too small to be detected in some cases.1, 2 Cryptococcal pneumonia usually occurs in immunocompromised patients and excess cortisol production can theoretically produce a state of immunodeficiency. Development of cryptococcal pneumonia concomitant with Cushing syndrome (CS) was rare. Here, we report a case of pulmonary nodule in a patient with CS differentiated with ectopic ACTH-producing tumor. Cryptococcal pneumonia was diagnosed following lung resection.

OBJECTIVETo evaluate the efficacy, toxicity and survival of intraoperative 125I brachytherapy combined with chemotherapy for advanced pancreatic cancer.

METHODSThirty-six patients with advanced pancreatic cancer were randomized to two groups: brachy-chemotherapy group (n = 18) and control group (n = 18). For the combined group, intraoperative 125I implantation and gemcitabine, 5-Fu were given. For the control group, intratumoral injection of absolute alcohol was done.

RESULTSThe CR + PR rate of brachy-chemotherapy group was 38.9% with pain relief in 77.8%, while that of control group was 0 with pain relief in 22.2% (P < 0.05). Although there were some toxicity in brachy-chemotherapy group, treatment was well tolerated. The 6-, 12-month survival rates of brachy-chemotherapy group were 71.4% and 21.4% and those of control group were 38.5% and 7.7%, respectively. The median survival time was 10.6 months and 5.2 months for the two groups, between which the difference was significant (P < 0.05).

CONCLUSIONInteroperative 125I brachytherapy combined with chemotherapy for advanced pancreatic cancer can control tumor, relieve pain and improve quality of life. It is safe and effective.

Objective To study the anatomical features of medial wall of the glomus jugulare to provide the theoretical direction for surgery of the glomus jugulare. Methods Fifteen (30 sides)formalin-fixed adult cadaveric specimens were dissected under the operating microscope, and their structural features of the medial wall of the glomus jugulare and their anastomosis of nerves were observed; and 5 dry skull specimen were also employed to observe the bone landmark of medial wall of the glomus jugulare. Results The medial wall of the glomus jugulare is composed of endocranial opening of the jugular foramen, jugular process of the temporal bone and occipital bone, cerebral dura mater and the Ⅸ, Ⅹ and Ⅺ cranial nerves. A curve line was marked on medial wall of the glomus jugulare, finding that the cranial nerves and the cerebral dura mater are at the anteroinferior position and the posterior-up part is composed of the well of the jugular vein adhered to the petrous bone and cerebral dura mater. Cranial nerve Ⅸ travels at the anterosuperior part of its own fibrous sheath and the inferior petrosal sinus ostium separates it from cranial nerves Ⅹ and Ⅺ; cerebral dura mater separates the cranial nerves Ⅸ and Ⅹ. The cranial nerve Ⅹ and the accessory nerve are closely related. Interval of cerebral dura mater between cranial nerve Ⅸ and Ⅹ is clearly seen in 86.67％ (26/30) patients and illegible in 13.33％ (4/30). Hypoglossal canal travels of the bottom of the medial wall of the glomus jugulare. Conclusion The medial wall of the glomus jugulare is composed of endocranial opening of the jugular foramen,jugular process of the temporal bone and occipital bone, cerebral dura mater and the Ⅸ, Ⅹ and Ⅺ cranial nerves, and this information can help the clinicians during the operations of the jugulare foramen, so that the operation complications can be reduced.

Objective We have summarized the clinical characteristics of inappropriate antidiuresis(SIAD).Methods We adopted retrospective analysis to analyze the clinical and lab data of 40 cases.Results The most common causes of SIAD were malignant tumor,lung disease,and central nervous system disease.The five major abnormal lab data were:hypochloraemia,hypouricemia,hyponitremia,hypocalcemia,and low hematocrit.Conclusion It is important to diagnose SIAD as soon as possible,and patient presented hyponatremia combined with hypouricemia must be suspected to have SIAD.

Objective To evaluate the effect of repetitive transcranial magnetic stimulation (rTMS) on serum brain-derived neurotrophic factor (BDNF) level in patients with schizophrenia.Methods Eighty hospitalized schizophrenics with refractory negative symptoms,admitted to our hospital from September 2012 to October 2013 and met the diagnostic and statistical manual of Mental Disorders-4th Edition (DSM-Ⅳ),were randomly divided into study group (n=40) and sham-operated group (n=40).The rTMS of 10 Hz on left prefrontal lobe was performed in study group and sham stimulation was used in sham-operated group; and the kinds and dosages of antipsychotics were preserved as before; other 40 healthy subjects were used as control group.Positive and Negative Syndrome Scale (PANSS) was performed and serum BDNF level was measured before and 4 weeks after treatment in all patients.Results BDNF level in both study group and sham-operated group before and after treatment was significantly lower than that in the control group (P＜0.05).The total PANSS scores and negative symptom scale scores in the study group after treatment were significantly decreased as compared with those before treatment (71.2±13.8 vs.63.3±11.4,t=2.721,P=0.008; 18.4±5.9 vs.22.8±6.6,t=3.064,P=0.003),and the BDNF level was statistically increased (8.74±2.76 vs.6.78±2.16,t=3.447,P=0.001).After treatment,the study group had significantly lower negative symptom scale scores and higher BDNF concentration than sham-operated group (t=2.470,P=0.016; t=3.180,P=0.002).For total PANSS scores,negative symptom scale scores and general psychopathology scale scores,the changed values before and after treatment of study group were all significantly higher than those in the sham-operated group (7.8±3.5 vs.2.0±0.9,t=9.893,P=0.000; 4.4±1.9 vs.0.5±0.2,t=12.584,P=0.000; 2.8±1.0 vs.0.9±0.4,t=10.875,P=0.000).For the study group,the changes of BDNF concentration showed no obvious correlation with the total PANSS scores or negative symptom scale scores (r=-0.156-0.247,P＞0.05).Conclusions The rTMS of 10 Hz on the left prefrontal lobe can increase the serum BDNF concentration of the schizophrenia.There is no correlation between the changes of BDNF concentration and improved negative symptoms.
