Objective To observe the efficacy and side effects of Jianpi Qutan Decoction combined with Quetiapine in the treatment negative symptoms of schizophrenia.Methods 60 inpatients with schizophrenia were randomly divided into two groups,with one group treated with Jianpi Qutan Decoction combined Quetiapine and the other group treated with Quetiapine.Effects and side effects were assessed with the Positive and Negative Syndrome Scale (PANSS) and Treatment Emergent Symptoms Scale (TESS) respectively 1,4 and 8 weeks before and after the treatment.Results There was no significant difference in the overall efficacy between the two groups,but the improvement of the negative symptoms and illness provocation was significantly better in the treatment group than that in the control group respectively (P＜0.05).Moreover,the adverse reaction was milder in the treatment group.Conclusion It is suggested Jianpi Qutan Decoction in combination with typical antipsychotics is effective and safe in treating negative symptoms in schizophrenia patients.

In this study, the expression of HSP70 during experimental tooth movement was dynamically observed and the relationship between HSP70 and orthodontic periodontal tissue remodeling were observed. The orthodontic appliance was placed between the right maxillary first molar and maxillary central incisors of adult SD rats to establish a rat molar movement model. Immunohistochemistry was performed 1, 3, 5, 7 and 14 day(s) after orthodontic force application to observe the expression and localization of inducible HSP70. The expression of HSP70 was strongly positive in the early stage of the tooth movement, became gradually less positive, and was weakly positive in the restoration stage. There was difference in staining pattern between different parts of PDL during the same period. These results suggest that the expression of HSP70 and difference in staining pattern among different parts of PDL during orthodontic tooth movement in rats may be implicated in stress response and remodeling of periodontal tissue.

The inter-rater correlation coefficient was 0.85, and the correlations among the items ranged from 0.78 to 0.94. The intra-rater correlation coefficient with the scale was 0.95, with the item correlations ranging from 0.72 to 0.97. Only item b230 Hearing function did not correlate well.Conclusions:The functioning assessment tool based on the ICF rehabilitation set when combined with a numerical rating scale has internal consistency, inter-rater reliability and intra-rater reliability sufficient for use in clinical practice.

Objective ToexploretheapplicationofVasoCT,astentimagingtechnique,instent-assisted coilaneurysmembolization.Methods Twentyconsecutivepatientswith23intracranialaneurysmswere treated with stent-assisted aneurysm embolization in the General Hospital of Armed Police Forces from December 2013 to November 2014 were enrolled. The patients performed VasoCT scan immediately after procedure. Then all the available images were used for stent-optimized reconstruction respectively. Under the XpertCT mode,the available images were observed with both volume imaging and maximum intensity projection. The available images were analyzed and they were divided into very clear,less clear,and not clearaccordingtothestentdevelopingclarity.Results Ofthe22aneurysmstreatedwithstent-assisted embolization,16 were occluded completely,6 were occluded partially. All the stents were expanded completely and were released to the expected locations;11 aneurysm stents developed clearly,9 developed less clearly,and 2didnotdevelopclearly.Conclusion VasoCTcanbeusedinthestent-assistedaneurysmembolization.It can clearly reveal the microscopic structure of the stents,location,relationship with the artery wall,and relationship between stents and coils. The clarity of stent development is associated with the diameters of the packed coils,and the stents are also affected by the metal artifacts projecting direction and the dense degree of the packing coils.

Objective To explore the relationship between thyroid hormone and colorectal adenomatous polyps (CAP) in middle-aged and elderly people.Methods We surveyed 3 042 middle-aged employees and retirees aged 45 years and over at a petrochemical enterprise of Ningbo.Their colonoscopic findings,body mass index,waist circumference and thyroid function were analyzed.Results Age and serum free triiodothyronine (FT3) of females with CAP were higher than those of the corresponding non-CAP group,so were age and waist circumference of males with CAP (P ＜ 0.05).Furthermore,these differences were statistically significant.The detection rate of CAP was significantly higher in males than in females (x2 =49.418,P ＜ 0.01).The detection rate of CAP was higher in females with higher levels of FT3.Multivariate unconditional logistic regression analyses showed the effects of thyroid hormone on the CAP differed by gender.Age and FT3 (OR =1.60,95％ CI:1.12-2.28,P =0.01) were correlated with CAP in females.However,only age and waist circumference were correlated with CAP in males.Conclusion Elevated FT3 may be a risk factor of CAP in elderly females.The detection rate of CAP may not be affected by FT3 levels in males.

ObjectiveTo study the MR Imaging features of breast phyllodes tumor (PT),and to correlate it with pathological results.MethodClinical and MRI findings were retrospectively reviewed in twenty-seven women with 28 PTs lesions confirmed by surgical pathology.Statistical analyses were one-way ANOVA for size analysis,Fisher exact test for analysis of MR appearances and Spearman correlation to study the relationship between MRI findings and BI-RADS categories.Results( 1 ) The histologic findings were benign,borderline and malignant PTs in 14.3％ (4/28),53.6％ (15/28) and 32.1％ (9/28) of lesions,respectively.(2) The mean maximum-diameter were (6.4 ± 3.9) cm,(5.7 ± 2.2) cm in borderline type and (4.8 ± 1.8)cm in benign type respectively.The results showed differences in lesion's size among the three type (F = 287.541,P =0.000),especially between malignant and benign type (P = 0.033 ).(3)Internal non-enhanced septations and silt-like changes on enhanced images,as well as time-signal curve on MRI correlated significantly with the histological grade ( P ＜ 0.05 ).( 4 ) If the category BI-RADS ≥ 4a was considered to be a suspicious sign for malignant lesion,the diagnostic accuracy of MRI would be 96.4％ (27/28),and the BI-RADS category of the MRI could reflect the PT's histological grade with a low correlation coefficient ( r = 0.382,P = 0.045 ).Conclusion The findings of PT on MRI have some characteristics,with tumor size and several MRI features correlating with the histological grade of breast PT.

A reasonable and practicable quality standard was developed for mori liquid extract from different sources by TLC, HPLC and fingerprint technology. In TLC method, the compounds were separated on polyamide film using glacial acetic acid-water (1: 3) as mobile phase at a UV wavelength of 365 nm. All qualified samples had the spots of the same color as the control herb and substance. The RP-HPLC method was used to determine the content of mulberroside A with mobile phase of methanol-water (25: 75) at a wave-length of 326 nm. The mulberroside A was in good linear with a regression equation of Y = 46.965X (r = 0.999 6) in the range of 4.6 - 228 mg x L(-1). In 14 batches of samples, the mulberroside A in 4 batches of them was less than 0.5 g x L(-1), and was more than 2.0 g x L(-1) in the other batches. It was suggested that the content limit of mulberroside A should be no less than 1.5 g x L(-1). The HPLC fingerprints were evaluated by the similarities. It has found that the similarities of different mori liquid extracts were very low and the chemical diversity of mori cortex was the major factor of similarity. Moreover, the process impact was minimal. Thus the fingerprint was not included in this quality standard.
