Objective Calcified epithelioma is a rare benign tumor in head and face. It is seldomly seen canceration. But it has local invasion behavior. The aim of this study was to explore the methodology in the diagnosis and treatment of calcified epithelioma in head and face, and to improve the accuracy of clinical diagnosis. Methods A retrospective analysis was carried out in 26 patients with calcified epithelioma in head and face. Results 53. 8 % patients with calcified epithelioma were less than 13-year-old. The disease was easily misdiagnozed. In this group of patients the misdiagnosis rate reached to 42. 3 %. Btype ultrasonographic diagnosis possessed a high level of concordance with histological diagnosis. There were three major types of calcified epithelioma: type 1, a mass with internal echoic foci; type 2, a hyperechoic mass with high beam; type 3, no calcification in the parenchyma. Piomatricoma was described as a skin tumour histologically composed of shadowcells, basophillic cells, foreign body giant cells and intracellular and stromal calcification. The treatment was excision and no recurrences were found by followup. Conclusions It is important for clinicians to know the clinical features of calcified epithelioma. Imaging studies including ultrasonography would help establish the diagnosis. Surgical excision with clear margins is recommended for this tumor.

Objective To investigate the action of interlukin-2(IL-2),interlukin-6(IL-6) and its soluble receptors (sIL-2R,sIL-6R) in the first episode of depression in the patients of Uyghur nationality and the differences in IL-2,IL-6 and sIL-2R,sIL-6R levels between the responsive depressed patients and the refractory depressed patients treated with venlafaxine.Methods A case-control study design was conducted.57 first-episode patients with depression (patient group) and 55 healthy people matched with gender and age (control group) were recruited in the study.An intervention with sustained-releasing venlafaxine tablets at fixed dose of 150 mg/d was performed in the patient group.The severity of the illness was evaluated by using the Hamilton's depression scale (HAMD-17) before and after the therapy.And by calculating the reduction rate of HAMD-17 (≥ 50％ or ＜50％),the patients were divided into the responsive or refractory groups.The serum levels of IL-2,IL-6,sIL-2R and sIL-6R in patients and controls were tested by ELISA,and a re-test was done with the patients after treatment.Results There were statistical significant differences of the levels of serum IL-2,IL-6 and sIL-2R,sIL-6R between the patients and the control group (P ＜ 0.01).After treatment,the levels of serum IL-2,IL-6,sIL-2R and sIL-6R in responsive patients were significantly decreased when compared with those before the treatment(P＜ 0.01).The four indexes of refractory patients didn' t alter after venlafaxine treatment (P ＞ 0.05).There were positive correlations between HAMD,serum IL-2 (r =0.677 ; P =0.000) and IL-6 (r =0.197 ; P =0.033) before treatment in all patients.Conclusion Serum IL-2 and IL-6 may play a role in the onset of the depression.The efficacy of venlafaxine is negatively correlated with the levels of serum IL-2 and IL-6.Regulating the imbalanced inflammatory cytokines and the immune system may be one of the mechanisms of drug therapy of depression.

Objective To purify asprosin protein expressed in Escherichia coli expression system and to study its effect on cardiac function.Methods Coding sequence of asprosin was obtained from GenBank.Codon optimization was performed according to the codon preference of E.coli.After gene synthesized, recombinant plasmid was made.Asprosin was then induced and purified by Ni-affinity purification.The mouse model of impaired cardiac function was established by ligating and relaxing the left anterior descending coronary artery.30 mice were randomly divided into 3 groups: sham operation group (sham), cardiac dysfunction group (MI/R) and cardiac dysfunction plus injection of recombinant asposin protein group (MI/R+rAsp).The left ventricular function was detected by echocardiography to determine the improving effect of recombinant asprosin protein on cardiac function.Results After prokaryotic expression and purification, the purity of the target protein was higher than 95%, and the endotoxin content was less than <0.1 EU/μg protein, which was suitable for cell and animal studies.After the recombinant asprosin protein was given, the left ventricular function of the mice was improved significantly (P<0.05).Conclusions Asprosin acts as a myocardial protective molecule to improve cardiac function.

Objective To study the sectional anatomy of the cardiac septum to provide the reference for clinical imageology and surgery. Methods Sixteen normal adult hearts without organic lesions were verified macroscopically. After vascular perfusion, the specimens were embedded with gel, fixed with 5% formalin, and cryopreserved for a week, and then were sectioned with the Digital Sectioner. Results A total of 1 608 slices (thickness: 0.2 mm) of the heart were obtained. Cardiac septum and the surrounding structures were shown clearly. The demarcation of connective and muscular tissues was clear. The diameters of the cardiac apex, fossa ovalis, brawny intraventricular septum, left ventricle, right ventricle, left and right fibrous trigone were measured with Photoshop6.0. Conclusion The clear images can display tiny structures that could be measured, which could provide anatomical references clinical imageology and surgery.
