AIM:To study the effect of different surgeries for vision and postoperative complications in leprosy patients with lagophthalmos.METHODS:A retrospective analysis.Totally 68 leprosy patients (97 eyes) with lagophthalmos were selected who treated with different surgeries during May 2007 to September 2015 in our sanatorium.The surgeries included nylon thread correction surgery, tarsorrhaphy, temporalis transposition surgery.We observed and compared the best corrected visual acuity(BCVA) and the rate of postoperative complications, such as epiphora, lacrimal duct injury, hard to open eyes, infection at the inner and lateral canthus and scar formation of lacrimal apparatus.RESULTS:The effect on BCVA of patients treated with nylon thread correction surgery and tarsorrhaphy:the preoperative and postoperative BCVA was significantly different of the two groups (Z=-4.193,-4.213;P<0.05);the preoperative and postoperative BCVA was not significantly different of the patients underwent temporalis transposition surgery (Z=-1.532, P >0.05).The postoperative complications:(1) epiphora:there was 91% in patients underwent nylon thread correction surgery, 89% in patients underwent tarsorrhaphy, 59% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=12.198, P<0.05);(2) lacrimal duct injury:there was 66% in patients underwent nylon thread correction surgery, 95% in patients underwent tarsorrhaphy, 41% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=22.415, P<0.05);(3) hard to open eyes:there was 56% in patients underwent nylon thread correction surgery, 55% in patients underwent tarsorrhaphy, 22% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=8.795, P<0.05);(4) infections:there was 84% in patients underwent nylon thread correction surgery, 3% in patients underwent tarsorrhaphy, 11% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=60.858, P<0.05).CONCLUSION:There are certain clinical efficacy for lagophthalmos caused by leprosy after surgery, especially patients after temporalis transposition surgery can close eyes by oneself.And their vision does not change significantly, which suggests that this surgery may prevent exposure injury for cornea.But the iatrogenic injury, the vision decrease in patients underwent other surgeries and the ocular tissue damage, such as epiphora, lacrimal duct injury, hard to open eyes, infection at the inner and lateral canthus and scar formation of lacrimal apparatus should be pay more attention to.

Purpose To describe the clinical and pathological features of atypical vascular lesions (AVLs) after conservative surgery and radiation of the breast cancer,and to discuss the association with post-radiation angiosarcoma.Methods The clinical and pathological features in one case of AVLs was evaluated.The literatures were reviewed.Results The patient is a 57-yeAR~-old female who underwent a conservative surgery of the right breast because of a carcinoma.She received standard dose of radiation as adjuvant therapy.Three years later, multiple erythematous plaques developed around the former scar, which radiated to the nipple.Clinically,the plaques were considered as relapses of the carcinoma.However, fine needle aspiration gave negative results.Biopsy of one large plague revealed a circumscribed vascular lesion confined to the superficial dermis.It was composed of thin-walled anastomosing lymphatic vessels lined by attenuated endothelial cells.In focal areas, the vessels extended to the mid-dermis.Immunohistochemically, the endothelial cells were positive for CD31, CD34 and D2-40,with absent of α-SMA positive pericytes.Review of the breast tumor sections showed an invasive micropapillary carcinoma.Conclusions AVLs is a rare vascular lesion related with conservative surgery and post-radiation therapy of the breast.AVLs may represent as a precursor of breast angiosarcoma.Being familiar with the clinicopathologic characteristics of AVLs is important not only for the pathologists but also for the clinicians.

OBJECTIVETo evaluate the clinical efficacy and safety of phosphodiesterase 5 (PDE-5) inhibitors for erectile dysfunction (ED) in patients with diabetes mellitus and provide some evidence for the clinical treatment of the disease.

METHODSWe searched MedMed, EMbase, Cochrane Library, CNKI, Wan Fang Data, VIP and ZADL for randomized controlled trials on PDE-5 inhibitors for ED in diabetic men and evaluated the methodology of the included trials with the Jadad scale. We used the erectile function domain in the IIEF (IIEF-EF), IIEF questions (IIEF-Q) 3 and 4, SEP-2 and -3, and Global Assessment Questions (GAQ) as the main evaluation indexes and employed the Review Manager 5. 1. 0 software for meta analysis.

RESULTSA total of 13 studies were included, which were all high quality trials with Jadad score > 3. The IIEF-EF scores in 10 of the included studies were subjected to meta analysis using the random-effect model (REM), with a weighted mean difference (WMD) of 5.64 (95% CI 4.41 - 6.83, P < 0.001). The fixed-effect model (FEM) analysis of the IIEF-Q scores in 6 of the studies showed the WMD to be 0.96 (95% CI 0.83 -1.08, P < 0.001) for IIEF-Q3 and 1.11 (95% CI 0.98 - 1.25, P < 0.001) for IIEF-Q4. FEM analysis of the SEP-2 scores showed WMD = 17.67 (95% CI 12. 38 - 22. 97, P < 0.001) in 2 of the studies, and that of the SEP-3 scores WMD = 23.64 (95% CI 17. 49 - 29.79, P < 0.001) in 5 of the studies. The GAQ scores in 11 of the studies were subjected to REM analysis, with OR = 6. 20 and 95% CI 3.65 - 10.52 (P < 0.001). REM analysis was performed on the adverse reactions in 11 of the studies, with OR = 7.43 and 95% CI 4.11 - 13.44 (P < 0.001).

CONCLUSIONPDE-5 inhibitors can effectively and safely improve erectile function in patients with diabetes mellitus.

OBJECTIVETo study the relationship between serum testosterone levels and the plaque formation of the carotid artery in a population-based cohort of independently living healthy women above 60 years of age.

METHODSAnalysis of the healthy elders from a population-based cohort study in 9 communities of Beijing. Carotid intima-media thickness and atherosclerotic plaques were determined ultrasonographically. Serum testosterone levels were measured by immunoassay. The data were analyzed with ANOVA and logistic regression analysis.

RESULTSThere was an inverse correlation between testosterone and plaque formation in old females (P < 0.01), while no association was found in males. Female with testosterone levels in the lowest quartile (< 0.49 nmol/L) had more risk of plaque formation (OR = 3.805, P < 0.01) after adjusted with age and other traditional factors of atherosclerosis.

CONCLUSIONTestosterone concentrations are negatively associated with carotid artery atherosclerosis in old women in Beijing, experimental and prospective studies are needed to determine the possible therapeutic role of testosterone in atherosclerosis.

We have developed a sensitive and rapid lateral-flow immunoassay (LFIA) for WSSV,using colloidal gold as an indicator.The fusion protein,VP (19+28),was expressed in E.coli,purified and used to prepare polyclonal antibodies.The purified anti-VP (19+28) IgG were conjugated with colloidal gold.Unconjugated anti-VP (19+28) IgG and goat anti-rabbit IgG were immobilized on nitrocellulose membranes.After assembly,three groups (5 individual animals in each group) of shrimp samples were tested which included healthy,moribund and dead shrimps.For each group,three different tissues (body juices,gills and hepatopancreas) were tested at the same time.In parallel,all the samples were also analyzed using PCR for comparison.Out of 45 samples tested,30 were detected as positive while 15 were classified as negative.The results of LFIA correlate with those obtained by the PCR analysis,indicating that these two detection methods have the same efficacy in the limited number of samples tested in this preliminary study.

Objective To investigate the characteristics and essential points of diagnosis and treatment of double trisomy 47,XXX/48,XXX,+8 combined Behcet disease, a rare inherited immunodeficiency disorder. Methods The clinical manifestations, karyotype analysis and gene test results of the patients were analyzed, and relevant literatures were reviewed. Results A 11-year-old girl presented repeated fever for more than 6 years, accompanied with recurrent genital herpes infection and oral apthosis, was clinically diagnosed with Behcet disease. Cytogentic and molecular karyotyping on peripheral lymphocytes demonstrated 47,XXX[12]/48,XXX,+8[18]. Conclusions Conventional karyotype analysis and chromosomal microarray analysis have a complementary role in the diagnosis of the disease. We conclude that patients with constitutional trisomy 8 and those with trisomy 8 confined to the bone marrow are both at increased risk of developing features of Behcet disease. The mechanism may relate to increased gene dosage of candidate genes for Behcet's disease on chromosome 8.

[Summary] Microcephalic or Majewski's osteodysplastic primordial dwarfism type Ⅱ ( MOPD Ⅱ) is an extremely rare genetic disease mainly caused by pericentrin ( PCNT) gene mutations. This paper reported one 13-year-old boy, who was admitted because of the slow growth for more than 13 years and deepened skin color over six months. He was diagnosed as MOPD Ⅱ associated with a combination of growth hormone deficiency, type 2 diabetes, hypertension, acanthosis nigricans, multiple café-au-lait spots. On magnetic resonance imaging of brain, no vascular malformations such as aneurysms were shown. There were novel compound heterozygous mutations of PCNT gene in the patient, with the nonsense mutations of c. 502C > T ( p. Gln168 * heterozygous variation) and c. 3103C > T (p. Arg1035* heterozygous variation). His father carried a nonsense mutation c. 3103C > T ( p. Arg1035 *heterozygous variation ) and his mother had a nonsense mutation c. 502C > T ( p. Gln168 * heterozygous variation). After treatment with metformin for three months, his blood glucose returned to normal, and acanthosis nigricans was improved. It seems critical to evaluate the abnormal condition of blood vessels regularly for MOPD Ⅱpatients with PCNT gene mutations.
