Objective To explore the clinical characteristics, treatment and outcomes of patients with panniculitis. Methods Clinical data of patients with panniculitis admitted to our hospital were analyzed and followed up. The disease was classified into two sub-types: cutaneous type and systemic type. The clinical profile and treatment as well as the outcomes were compared. Results The mean follow up time of 61 in-patients with panniculitis was 49.2 months (range: 2～216 months). Remission could be achieved in 17 patients, recurrent episodes happened in 26 patients. Eighteen patients turued out to be diffuse connective tissue disease (CTD), hematological disorders, malignant tumors and tuberculosis during follow-up. The age at sympton onset was 33±17 years old in 43 patients with primarily panniculitis which eutaneoua sub-tye was 12 patients and systemic sub-tye was 31 patients. The male: female ratio was 1:15. Patients with systemic sub-type were associated with liver (25 patients), spleen (23 patients), respiratory system (11 patients), kidney (12 patients), and circulatory (3 patients) system involvement. Nine patients with systemic sub-type presen-ted white blood cell decrease while none of in the cutaneous sub-type. The difference was significant (P=0.044). Biopsy of the lesions had shown nuclear dust in 16.3% of primarily panniculitis patients. Conclusion Pannieulitis can associate with systemic rheumatic diseases, malignant tumors, hematological disorders and tuberculosis. The main systemic involvements with systemic sub-type are liver and spleen, and may have whiteblood cell decreasing. Some patients could achieve remission when treated with corticosteroids and/or immunosuppressive drugs. However,the majority of patients will have recurrences when corticosteroids is tapered.

The expressions of estrogen receptor (ER) α,ERβ1,and ERβ2 in thyroid carcinoma,thyroid adenoma,and adjacent normal thyroid tissue were determined by RT-PCR and immunohistochemistry,and the relationship of expression levels of three ERs and the main clinical pathologic parameters were evaluated.The result showed that ERα mRNA expression in papillary thyroid carcinoma(PTC) tissues was significantly higher than adjacent normal tissue,while,ERβ2 mRNA expression in PTC tissues was significantly lower than normal tissue ( P＜0.05 ).The positive expression of ERβ1 and ERβ2 in the thyroid carcinoma was related with the histological variant of carcinomas; the ERβ2 expressions were related with the lymph node metastasis and TNM staging of the carcinomas.These results suggest that the decreased ERβ2 expression may induce proliferation and carcinogenesis of thyroid follicular epithelial cells as well as progression of the carcinoma,and is a powerful prognostic indicator.

Objective: To study the role of basic fibroblast growth factor (bFGF) during human tooth germ development.Method: bFGF expression was exmined with immmunohistochemical technique in bud stage,cap stage and bell stage of human tooth germ from aborted embryo of 7,8,10 and 14 weeks.Results: At the bud stage of human tooth development, bFGF was expressed in most dental epithelium cells,and few condensed mesenchymal cells.At the cap stage ,bFGF was weakly expressed.At the bell stage,bFGF was strongly expressed in the inner enamel epithelium layer and dental papillary cells near inner enamel epithelia,weakly in the stellate reticulum.Conclusion:During human tooth development,bFGF plays an important role in the proliferation and differentiation of dental epithelium.

Objective To investigate if pretreatment with repeated electroacupuncture (EA) at Baihui acupoint could increase HSP 70 expression after cerebral ischemia-reperfusion injury in rats.Methods Twenty male SD rats weighing 280-320 g were randomly divided into 2 equal groups of ten : control group received no pretreatment and EA group received pretreatment with EA at Baihui acupoint 30 min a day for 5 days. The animals in both groups were anesthetized with isoflurane. Right common carotid artery (CCA) , external and internal carotid artery (EGA, 1C A) were exposed through a longitudinal incision in the neck. EGA was ligated and a 3-0 nylon monofilament (Ethicon) with rounded tip was inserted into ICA and threaded cephalad until resistance was felt. In this way middle-cerebral artery was occluded for 120 min in both groups. The nylon filament was then withdrawn to allow reperfusion. The animals were allowed to recover. At the end of 24 h reperfusion, the animals were anesthetized with intraperitoneal pentobarbital 40 mg?kg-1 and killed. Brain was immediately removed. Two pieces of brain tissue were obtained from right parietal lobe for microscopic examination (HE staining) and determination of expression of heat shock protein (HSP) 70 using immuno-histochemistry technique.Results In EA group the levels of HSP 70 expression were significantly increased (1.94?0.57) compared with those in control group (0.86?0.35) ( P

Objective To prepare human anti-postsynaptic neurotoxin monoclonal antibody from phage antibody library using recombined postsynaptic short-chain neurotoxins ofLapemis curtus.Methods The three postsynaptic neurotoxins were expressed inEscherichia coli and phage antibodies against neurotoxins were screened. The obtained scFvs were further constructed to full antibodies. The antigen binding ability, biochemical and pharmacokinetic characteristics of the depurated antibodies were evaluated, and the anti-toxin effects of the antibody drugs were verifiedin vivo.Results Two positive scFvs with specific binding ability to all the three neurotoxins were obtained after 4 rounds of panning, and then the full antibodies were generated, expressed and purified. Antibody binding specificity was further confirmed. Pharmacokinetics of these two antibodies, SM-SD-911 and SM-SD-861 were similar to a conventional IgG molecule. SM-SD-911 and SM-SD-861 also showed strong antitoxin effectin vivo. Conclusionfull human anti-postsynaptic neurotoxin antibody has been successfully obtained by using recombinant neurotoxin technology and a large phage antibody library which may achieve clinical efficacy in navy medical applications.

Objective To observe the clinical effect of treating advanced esophageal carcinoma with three-dimensional conformal radiotherapy combined with chemotherapy and traditional Chinese medicine.Methods 36 cases with advanced esophageal carcinoma were randomly divided into a eontrol group and a treatment group.The control group was treated with conventional radiotherapy combined with chemotherapy,and the treatment group was treated with three-dimensional conforrnal radiotherapy combined with chemotherapy and traditional Chinese medicine.The short-term effect,toxicity and long-term effect were observed,and cause of death was analyzed.Results The complete remission rate in the treatment group was significantly higher than that of the control group(P＜0.05).The toxicity of the treatment group was markedly decreased.One and three years'survival rate between the two groups had a significant difierent(P＜0.05),but five years'survival rate between the two groups had no significant difference(P＞0.05).Local uncontrolled rate and recurrence rate in the treatment group were significantly lower than those in the control group(p＜0.05).Conclusion The treatment of three-dimensional conformal radiotherapy combined with chemotherapy and traditional Chinese medicine on advanced esophageal carcinoma was better than conventional radiotherapy combined with chemotherapy.

Prepulse inhibition ( PPI) is the suppression of the startle reflex when the startling stim-ulus is preceded by a non-startling stimulus ( the prepulse) . It is an operational measurement of sensorimotor gating mechanism to help the brain adapt to the complex environment,which could be top-down modulated by attention and other higher cognitive processes. Deficits of PPI and the top-down modulation of PPI are closely related to psychiatric diseases. Research papers published from January 2001 to October 2016 related to PPI in psychiatric disorders were searched in the Chinese and English databases. Results showed that schizo-phrenic patients and their relatives showed deficits in baseline PPI as well as the attentional modulation of PPI,and more importantly,the attentional modulation of PPI rather than the baseline PPI was more related to the symptom severity. Patients with Tourette'' s syndrome showed PPI impairment,while patients with obsess-ive compulsive disorder had lower levels of PPI. PPI deficits in bipolar disorder patients were gender-depend-ent. Studying PPI and the top-down modulation of PPI could provide a basis to study the interaction of senso-ry processing and attention,and facilitate the researches of neural mechanism underlying the deficits of senso-ry gating. To establish advanced paradigms of PPI,new cognitive components could be introduced,such as at-tention,emotion,motor control,compulsivity and so on,thus improving the specificity of PPI test and promo-ting the PPI test as new biomarker and endophenotype in various psychiatric disorders.
