SUMMARY To explore the clinical pathological characteristics and improve the recognition in the diag-nosis and treatment of basal cell carcinoma (BCC)of prostate.Three cases of BCC of prostate were re-ported and the relevant literature was reviewed to investigate the diagnosis and treatment of this disease. We analyzed three cases of prostatic BCC.Their ages were within a range of 57 to 83 years.One of them complained of hematuria and two complained of dysuria.All of them presented with prostatic hyperplasia. Two of them presented with high prostate specific antigen (PSA)and one with normal PSA.Case 1 had prostate cancer invasion of bladder,rectal fascia,with lymph node metastasis,bone metastasis and lung metastases.The patient received bladder resection +bilateral ureteral cutaneous ureterostomy +lymph node dissection on November 2,2014 .Postoperative pathological diagnosis showed BCC.Reexamination of pelvic enhanced MRI in January 8,2015 suggested pelvic recurrence.Abdominal enhanced CT showed multiple liver metastases and pancreatic metastasis on July 11,2015.Prostate cancer specific death occurred in October 2015.Case 2 was diagnosed as BCC in prostate biopsy on March 27,2015. Positron emission tomography and computed tomography (PET-CT)showed pulmonary metastasis and bone metastasis.Then the patient received chemotherapy,endocrine therapy and local radiation therapy. Reexamination of PET-CT on January 11,2016 showed that the lung metastase tumors and bone metas-tase tumors were larger than before.Up to January 10,2016,the patient was still alive.Postoperative pathological changes of transurethral resection of prostate (TURP)in case 3 showed BCC might be con-sidered.The PET-CT suggested residual prostate cancer,which might be associated with bilateral pelvic lymph node metastasis.In April 20,2016,the review of PET-CT showed pelvic huge irregular hybrid density shadow,about 14.5 cm ×10.0 cm ×12.9 cm in size,and tumor recurrence was considered. Then the patient received local radiation therapy.The patient survived in the followed upon January 10, 2016.BCC of prostate is a rare subtype.Due to the local infiltrative and distant metastatic potentiality, active management is preferred and a life-long follow-up is necessary.

The main purpose of this paper is to explore the applicability of multivariate multilevel models for bioequivalence evaluation. Using an example of a 4×4 cross-over test design in evaluating bioequivalence of homemade and imported rosiglitazone maleate tablets,this paper illustrated the multivariate-model-based method for partitioning total variances of In (AUC) and In (C_(max)) in the framework of multilevel models. It examined the feasibility of multivariate multilevel models in directly evaluating average bioequivalence (ABE),population bioequivalence (PBE) and individual bioequivalenc (IBE). Taking into account the correlation between In (AUC) and In (C_(max)) of rosiglitazone maleate tablets,the proposed models suggested no statistical difference between the two effect measures in their ABE bioequivalence via joint tests,whilst a contradictive conclusion was derived based on univariate multilevel models. Furthermore,the PBE and IBE for both In (AUG) and In(C_(max)) of the two types of tablets were assessed with no statistical difference based on estimates of variance components from the proposed models. Multivariate multilevel models could be used to analyze bioequivalence of multiple effect measures simultaneously and they provided a new way of statistical analysis to evaluate bioequivalence.

OBJECTIVE:
To investigate the change of carotid intima-media thickness (IMTc) and serum matrix metalloproteinases-9 (MMP-9) levels in newly diagnosed Type 2 diabetic patients, and to analyze the relationship between MMP-9 and IMTc; at the same time, to assess the effect of rosiglitazone on IMTc and MMP-9 levels.
METHODS:
Fifty-eight patients with Type 2 diabetes mellitus were selected in our study, and 25 healthy adults served as normal controls. Diabetic patients were divided into 2 groups: Group A (31 subjects) were treated with rosiglitazone (4 mg/d), and Group B (27 subjects) were treated with metformin alone (500 approximately 1,500 mg/d). They all received the treatment for 3 months. The IMTc was measured by high resolution ultrasonography, and the serum MMP-9 was determined by enzyme linked immunosorbent assay (ELISA) to assess the relationship between IMTc and MMP-9.
RESULTS:
The mean level of serum IMTc and MMP-9 in Type 2 diabetic patients was significantly higher than that in healthy adults (P < 0.05). After treatment with rosiglitazone and metformin, IMTc and serum MMP-9 levels decreased significantly (P < 0.05). There was no obvious change in IMTc and serum MMP-9 levels in group B before and after the treatment (P = 0. 071, P = 0.065). Using multiple linear stepwise regression analysis, the significant correlation between IMTc and HbA1C, BMI, WHR, HDL-C, MMP-9 were discovered.
CONCLUSION
IMTc and MMP-9 levels increase in newly diagnosed Type 2 diabetic patients, suggesting that there is closely relationship between serume MMP-9 levels and early diabetic macrovascular disease. IMTc and MMP-9 can be reduced significantly in the newly diagnosed diabetic patients after being treated with rosiglitazone, which may be one of the protective mechanisms of vascular vessels.

OBJECTIVETo understand the changing trend of occupational hazard of industries in Shunde area and to provide the scientific evidence for the prevention of occupational diseases.
METHODSThe pre-evaluation of occupational hazard was carried out for the construction projects. The data about employee number scale, industry species, occupational hazard factors, hazard levels and prevention measures for construction projects were collected and analyzed. The data of Shunde Occupational Health Survey in 2011 served as the control data.
RESULTSThere were 258 construction projects in 2010 and 2011, in which the proportions of medium and large scales increased to 8.1% and 2.4% respectively, the proportions of the furniture and chemical industries decreased from 25.6% or/and 5.1% to 2.7% or/and 1.8%, the proportions of the high-tech industries increased from 1.8% to 9.2%. The proportions of the projects with serious, medium and slight occupational hazard levels were 4.3%, 67.8% and 27.9%, respectively. The proportions of the projects with harmful chemicals, dusts and physical factors were 34.2%, 46.8%, 42.6%, respectively.
CONCLUSIONThe feature of occupational hazard in Shunde industries has changed at upgrading stage. We should pay attention to the prevention of occupational diseases in high-tech industries.

OBJECTIVETo investigate the protective effect and mechanism of curcumin derivatives B06 on myocardium from type 2 diabetic rats.
METHODSThirty-five male SD rats were randomly divided into 5 groups, normal control group (NC group), high fat group (HF group), high fat treatment group (FT group), diabetes mellitus group (DM group) and diabetes treatment group (DT group) (n = 7). The late four groups were fed with high fat food, after four weeks of high fat feeding, the rats from DM group and DT group were injected with low dosage of streptozocin intraperitoneally to induce diabetes mellitus, FT group and DT group were gavaged with curcumin derivatives B06 at the dosage of 0.2 mg/kg x d. The blood glucose and lipid were detected biochemically, blood insulin was assayed by ELISA and the insulin resistance index was calculated, the morphology of myocardium was observed by light and transmission electron microscopy, the protein expression of AMP-activated protein kinase alpha (AMPKalpha) and phosphorylated AMP-activated protein kinase alpha (p-AMPKalpha) in myocardium were tested by Western blot.
RESULTSThe level of blood glucose, lipid, insulin and the insulin resistance index were increased in HF group and DM group, but they were decreased after the treatment with B06. The expression of AMPKalpha and p-AMPKalpha were decreased, but they became increased after the treatment of B06. There were increased collagen fibers in interstitium and expansion of mitochondria in cytoplasm of myocardium from DM group, but they were ameliorated in B06 treatment group.
CONCLUSIONIt is suggested that B06 may relieve the damage of myocardium from type 2 diabetic rats and the increased expression of AMPKalpha and p-AMPKalpha may be involved in it.

BACKGROUNDThe blood supply to the eye comes from the retinal central vascular system of the ophthalmic artery and the ciliary vascular system. The ophthalmic artery stems from the ipsilateral internal carotid artery. If occlusion or stenosis occurs in the carotid artery, the blood perfusion to the ophthalmic artery becomes insufficient, leading to signs and symptoms of anterior and posterior ocular ischemia. The objective of this study was to evaluate the clinical characteristics and risk factors of ocular ischemic diseases caused by carotid artery stenosis.
METHODSThis study was a retrospective review of 145 patients with carotid artery stenosis. Fifty-eight patients who had symptoms of ocular ischemic disease caused by carotid artery stenosis formed group A and the other 87 patients who only had carotid artery stenosis formed group B. We analyzed the causes and course of disease, and relative risk factors, by comparing the two groups.
RESULTSThe degree of carotid artery stenosis in group A was higher than that in group B. And group A had a greater decrease of ophthalmic artery flow. Male, hypertension, hyperlipidemia, and smoking were significantly related to carotid artery stenosis. Amaurosis fugax was the most common ocular symptom in group A. The ocular ischemic diseases mainly included ischemic optic neuropathy, central/branch retinal artery occlusion, ophthalmoplegia externa, and ocular ischemic syndrome.
CONCLUSIONSCarotid artery stenosis correlates with ocular ischemic diseases. Ophthalmologists must observe for ocular symptoms, which were the onset symptoms in some patients.
