ABSTRACT
Paraneoplastic pemphigus is a rare autoimmune bullous dermatosis, which is caused by potential neoplasm, especially the Castleman's disease. Castleman's disease associated with paraneoplastic pemphigus is misdiagnosed frequently and easily in clinical practices. Furthermore, it is reported that the mortality rate for this disease is very high. Bronchiolitis obliterans is the most common complication and the most important cause of death. There was a female patient presenting recalcitrant mucocutaneous erosions, ulcers and scattered erythemas in the body. The patient was diagnosed and treated for pemphigus vulgaris with little success in Xiangya Hospital, Central South University in January 2015. Further investigations confirmed the diagnosis of paraneoplastic pemphigus with retroperitoneal tumor. Subsequently, the patient was treated with tumor resection in combination with intravenous immunoglobulin and corticosteroids. The pathology revealed that it was the Castleman's disease. Her mucocutaneous performance recovered obviously and the bronchiolitis obliteran did not appear in the follow-up. Castleman's disease associated with paraneoplastic pemphigus should be considered when mucosal and skin lesions showing no improvement under corticosteroids. Early and complete removal of the tumor together with immunotherapy could be beneficial to the patient's prognosis.

Objective: To evaluate the clinical characteristics and epidermal barrier function of papulopustular rosacea by comparing with acne vulgaris
Methods: Four hundred and sixty-three papulopustular rosacea patients and four hundred and twelve acne vulgaris patients were selected for the study in Xiangya Hospital of Central South University from March 2015 to May 2016. They were analyzed for major facial lesions, self-conscious symptoms and epidermal barrier function
Results: Erythema, burning, dryness and itching presented in papulopustular rosacea patients were significantly higher than that in acne vulgaris patients [P<0.001]. The clinical scores of erythema, burning, dryness and itching in papulopustular rosacea patients were significantly higher than those in acne vulgaris patients [P<0.001]. The water content of the stratum cornuem and skin surface lipid level were both significantly lower in papulopustular rosacea patients than that of the acne vulgaris patients [P<0.001] and healthy subjects [P<0.001]; Water content of the stratum cornuem and skin surface lipid level were higher in acne vulgaris patients in comparison with that of healthy subjects [P>0.05, P<0.001; respectively]. Transepidermal water loss was significantly higher in papulopustular rosacea patients than that of acne vulgaris patients and healthy subjects [P<0.001]; transepidermal water loss was lower in skin of acne vulgaris patients than that of healthy subjects [P<0.001]
Conclusion: Erythema, burning, dryness and itching are the characteristics of papulopustular rosacea, which makes it different from acne vulgaris. The epidermal barrier function was damaged in papulopustular rosacea patients while not impaired in that of acne vulgaris patients
ABSTRACT
Objective To find out early lesion of rentanl function in elderly patients with dipper essential hyperten-sion and morning blood pressure surge( MBPS) , and to find out the value of homocysteine( Hcy) with high-sensitiv-ity C reactive protein ( hs-CRP) in detecting early lesion of rentanl function in hypertensive patients. Methods Totally 168 elderly paritents with dipper essential hypertension were divided into MBPS group( observation group, n=73) and non-MBPS group (control group, n=95) according to the accompanying MBPS or not. The cystatin C ( Cys C) , urinary microcalbumin ( U-mAlb) ,urinary transferring( U-TRF) ,Hcy, hs-CRP,serum creatinine( SCr) , blood urea nitrogen(BUN), blood glucose(Glu),cholesterol(TCH),triglyceride(TG), high density lipoprotein cholesterol( HDL-C) and low density lipoprotein cholesterol( LDL-C) were tested. The differences in Cys C, Hcy, hs-CRP, the U-mAlb positive incidence and the U-TRF positive incidence between the two groups were analyzed. Results There were no statistical concernments in SCr, BUN, GLu, TCH, TG,HDL-C,and LDL-C between the two groups. The amplitude of variation in morning systolic pressure peak was higher in MBPS group than in non-MBPS group(P=0. 000). The obvious varieties in the Cys C, Hcy,and hs-CRP were higher in MBPS group than in non-MBPS group ( P=0. 000 ) . The U-mAlb positive incidence was higher in MBPS group than in non-MBPS group(χ2 =18. 014,P =0. 000). The U-TRF positive incidence was higher in MBPS group than in non-MBPS group(χ2 =19. 694,P=0. 000). Conclusion MBPS has a great effect on Cys C,U-mAlb,U-TRF,Hcy and hs-CRP. MBPS is apt to cause early lesion of rental function in elderly patients with dipper essential hypertension. And Hcy and hs-CRP can be used to diagnose the early renal insufficiency.
ABSTRACT
Objective To explore the potential association between HLA-DRB1 Alleles and systemic scleroderma (SSc) of the Zhuang Nationality in Guangxi region. Methods Polymerase chain reaction-special sequence primers (PCR-SSP) was used to study the HLA-DRB1 alleles in 58 patients with SSc and 50 healthy controls of the Zhuang Nationalty in Guangxi Province. Comparisons between groups were performed with χ2 test or exact probabilities. Results Sixteen HLA-DRB1 alleles were discovered from the specimens,including 14 in the SSc specimens, and 16 in the control specimens. Among them,the allele frequencies of HLA-DRB1 * 1301 (7.760%, OR=9.000, χ2=4.341, P=0.037), HLA-DRB1 * 1305 (11.207%, OR=3.322,χ2=4.206, P=0.040) and DRB1 * 15 (26.724%, OR=2.679, χ2=6.038, P=0.014) were significantly higher in SSc patients than those of the controls (respectively for 1.000%, 4.000%, 15.000%). Conclusion Our data suggest that the HLA-DRB1 * 1301, HLA-DRB1 * 1305 and HLA-DRB1 * 15 may be the susceptible genes of SSc in Zhuang nationality population.
