To investigate clinical features of somatization disorder. Methods Seventy-nine paeeeeee with somatization disorder (SD), diagnosed based on the Chinese Classification and Diagnostic Criteria of Mental Disorders, version 3 ( CCMD-3 ) during September 2006 to August 2008, were selected and assessed by serf-edited somatic symptom list ( SSSL), symptom checklist-90 ( SCL-90 ), Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD). Results Sixty-two symptoms in two to six systems were involved in SDs, with a mean and standard deviation of 12.4 ± 6.6 symptoms in 4.2 ± 0.9 systems. The skin, nervous system, gastrointestinal system, respiratory and circulatory systems were the most involved in those symptoms. Depression, anxiety and hostile mood, number and total score of somatic symptoms all correlated positively with the total scores of HAMA and scores of somatic anxiety and mental anxiety (P < 0.01 ), but not with the total score of HAMD (P > 0.05 ). Conclusions Multiple systems were involved in SD, usually with complicated symptoms including depression and anxiety, which was prone to inappropriate medical diagnoses. Number and severity of somatic symptoms positively correlated with severity of anxious symptoms.

AIM To establish an HPLC method for the simuhaneous content determination of five flavonoids in Duchesnea indica (Andr.) Focke at five picking time (April,May,June,July and August).METHODS The analysis of D.indica methanol extract was performed on a 25 ℃ thermostatic Agilent ZORBAX SB-C18 column (250 mm×4.6 mm,5 μm),the mobile phase comprising of acetointrile-0.1％ methanoic acid flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelength was set at 350 nm.RESULTS Rutin,hyperoside,isoquercitrin,celereoin and kaempferol showed good linear relationships within their own ranges (R2 ≥0.998 6),whose average recoveries were 97.1％-101.5％ with the RSDs of 1.37％-2.37％.The contents of five constituents in samples at different picking time exhibited obvious differences,among which lutin and hyperoside contents were the highest in June,isoquercitrin content was the highest in July,and celereoin and kaempferol contents were the highest in August.CONCLUSION The suitable picking time of D.indica is June and July.

Objective To study the expression and role of galanin in the hypothalamus of rat with the drug-induced hyperprolactinemia.Methods Hyperprolactinemia was induced by daily intraperitoneal injections 50 mg/kg sulpiride solution.The protein in the hypothalamus of rat was extracted to determine the expression levels of galanin with Western Blot.The expression and colocalization of galanin and dopamine in model and control group were observed with immunofluorescence.Results The model group showed a significant increase of serum prolactin (PRL) level and a significant decrease of serum estradiol (E2) level,as compared to the control group ((15.74±2.49) ng/ml vs (10.25±1.29) ng/ml and (4.24±0.69)pg/ml vs (9.56±3.25) pg/ml,respectively,P＜0.05).Both the expression level of galanin and the number of neurons coexisting with galanin and dopamine were decreased in the hypothalamus of the hyperprolactinemia rat compared with the control group.Western Blot revealed that,compared to the control group,the sulpiride model group had a significant increase of galanin but not TH (0.405±0.112 vs 0.985±0.158,P＜0.05 and 0.871 ± 0.046 vs 0.890±0.054,P＞ 0.05,respectively).Conclusion Galanin expression level has decrease in the hypothalamus of the hyperprolactinemia rat,which contributes to the reduction of dopaminergic neurons.

Objective To study the variables of behavioral function and TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling) figure in Bcl-2 transgenic (TG) mice and control mice after spinal cord injury (SCI), thus to find new ideas and ways for diagnosing and treating SCI. Method The genesis of Bcl-2 overexpression transgenic (TG) mice were produced by injection of Bcl-2 plasmid into the fertilized ova of mice.Nine Bcl-2 TG mice and nine control mice were subjected to SCI of moderate severity at T10, with the use of weight dropping (WD) method (impact force 2.5～3.0 g·cm). Up to 1 day , 7 days, and 14 days after SCI,functional deficits were evaluated with BBB scales, and the apoptosis of neurons was investigated by using TUNEL method. Another three mice of control group were only treated with laminectomy without SCI for comparison. Results The mean functional scores in the control mice were lower than those in the Bcl-2 TG mice, although the unpaired T -test revealed no significant differences. On the other hand, the number of TUNEL positive neurons and IOD(Integrated Optical Density)score in the Bcl-2 TG mice were both significantly lower than those in the control mice. Conclusions This experiment suggests that overexpression of Bcl-2 may suppress neuronal apoptosis after SCI. The Bcl-2 may be an important factor in relieving the damage within CNS after trauma.

Objective To investigate the effect of hypoxic preconditioning on anti-inflammatory responses of bone marrow mesenchymal stem cells (BMSCs) in rats through in vitro and in vivo experiments.Methods In vitro experiment The isolated rat BMSCs were cultured by whole bone marrow adherence method.The cells at passage 3 were seeded in 24-well plates at a density of 1 × 106 cells/ml and randomly divided into 5 groups (n =8 wells each) using a random number table:control group (group C),normoxia-incubated group (group N),hypoxic preconditioning group (group H),hypoxia preconditioning + STAT3 inhibitor Stattic group (group HS) and hypoxia preconditioning + anti-IL-10 monoclonal antibody group (group HA).In group C,BMSCs were incubated in DMEM culture medium.In group N,BMSCs were exposed to21％ O2-74％ N2-5.0％ CO2 for48 h.In group H,BMSCs were exposed to 0.5％ O2-94.5％ N2-5.0％ CO2 for 24 h followed by 24 h exposure to normoxia.In HS and HA groups,500 μg/ml Stattic and 100 μg/rnl anti-IL-10 monoclonal antibody were added to the culture medium before hypoxia preconditioning,respectively.The expression of phosphorylated STAT3 (p-STAT3) and IL-10 was determined by Western blot.In vivo experiment Healthy male Sprague-Dawley rats,weighing 300-350 g,in which intrathecal catheters were successfully implanted without complications,underwent spinal cord ischemia by occlusion of the thoracic aorta combined with controlled hypotension.Three hundred rats with spinal cord I/R injury were randomly divided into C,N,H,HS and HA groups (n =60 each) using a random number table.Immediately after onset of reperfusion,DMEM medium 300 μl was injected intrathecally in group C,and BMSC suspension 300 μl (1 × 106 cells/ml) was injected intrathecally in N,H,HS and HA groups.Neurological function was scored before ischemia and at 4,12,24 and 48 h of reperfusion (T0-,).The animals were then sacrificed and the lumbar segment of spinal cord was removed for detection of the content of IL-10,TNF-α,IL-1β,IL-6,monocyte chemotactic protein-1 (MCP-1),and macrophage inflammatory protein-1 α (MIP-1 α) (by ELISA) and the number of activated microglia (by immuno-histochemistry).Results Compared with C and N groups,the expression of pSTATβ and IL-10 was significantly up-regulated,the neurological function score and IL-10 content were increased,the content of TNF-α,IL-1β,IL-6,MCP-1 and MIP-1α and the number of activated microglia were decreased in group H (P ＜ 0.05).Compared with group H,the expression of p-STAT3 and IL-10 in group HS and expression of IL-10 in group HA was significantly down-regulated,and the neurological function score and IL-10 content were decreased,and the content of TNF-α,IL-13,IL-6,MCP-1 and MIP-1α and the number of activated microglia were increased in HS and HA groups (P ＜ 0.05).Conclusion Hypoxic preconditioning can enhance anti-inflammatory effects of BMSCs,thus increasing BMSCs-induced reduction of spinal cord ischemia-reperfusion injury in rats.

Objective To investigate the value of prenatal ultrasound in diagnosis and treatment of twin reverse arterial perfusion (TRAP) syndrome. Methods A retrospective study was performed in 5 TRAP cases, including ultrasound images, clinical data and pregnancy outcomes. The sonographic characteristics were summarized. Results Five TRAP cases were diagnosed during 13 to 28 weeks' gestation and confirmed after birth. Color Doppler unltrasonography revealed retrograde umbilical artery perfusion towards acardiac twin. Two of 5 cases ended up in induced abortion, 1 in spontaneous abortion, 1 was delivered at 37 weeks' gestation after ultrasound-guided feticide of the acardiac twin and 1 was monitored closely with ultrasound and delivered alive at 32~(+4) weeks' gestation. Conclusion Prenatal ultrasonography has great applicative value for TRAP syndrome in early diagnosis, choosing optimal treatment and prognosis assessment.

Objective To investigate the correlation between enlarged perivascular space (EPVS) and post-stroke depression (PSD) in patients with ischemic stroke. Methods Consecutive patients with acute cerebral infarction admitted to hospital from March 2010 to March 2014 were enroled prospectively. The patients completed head MRI examination after admission and performed EPVS grading. At 3 months after symptom onset, they performed PSD assessment according to Hamilton Depression Scale (HAMD) and Classification and Diagnostic Criteria of Mental Disorders in China, 3rd edition (CCMD-3). The relationship between EPVS and PSD was analyzed. Results A total of 249 patients were enroled; including 62 patients (4. 9% ) experienced PSD at 3 months. There were significant differences in the proportions of the EPVS classification patients of the baseline National Institutes of Health Stroke Scale score ( the median [interquartile range]; 4 [3 - 6] vs. 3 [2 - 5]; Z = - 2. 950, P = 0. 003), centrum semiovale (χ2 = 14. 370, P = 0. 001), and periventricular (χ2 = 11. 590, P = 0. 003)between the PSD group and the non-PSD group. Multivariable logistic regression analysis showed that centrum semiovale EPVS grade 2 (odds ratio [OR] 3. 89, 95% confidence interval [ CI] 1. 59 - 9. 56) and grade 3 (OR 3. 28, 95% CI 1. 04 - 10. 33) were significantly correlated with PSD; periventricular EPVS grade 2 (OR 0. 72, 95% CI 0. 27 - 1. 91) and grade 3 (OR 2. 24, 95% CI 0. 68 - 7. 37) were not correlated with PSD. Conclusions Centrum semiovale EPVS is independently associated with PSD, and periventricular EPVS is not.
