The patient,a 11-year-old boy,presented with a 4-year history of erythema and vesicles on the face and arms as well as a 4-month history of tumor and ulcer on the extremities,accompanied by progressive fatigue and intermittent fever.The patient had a body temperature of 37.7℃.No lymph node involvement was observed.Cutaneous examination revealed minimally indurated pink-red patches on the face and nose and dusky red firm nodules and tumors of varying sizes on the extremities.The nodules ranged from 2.0 cm to 18 cm in diameter,some had necrosis and black crusts on the surface.Ulcers were observed in some of the larger nodules;many of the ulcers extended into the muscle layer.White purulent discharge was seen on the surface of many of the nodules.The lesions were sharply demarcated,firm,tender, and surrounded by small satelite nodules.Histologically,there were large quantities of irregularly shaped, middle-sized tumor cells with clear cytoplasm,large twisted nuclei and prominent chromatin,infiltrating from the epidermis to subcutaneous tissue.The tumor cells infiltrating the follicles and eccrine sweat glands were either distributed perivascularly in a nest shape,or dispersed.There were broken nuclei and reactive histio- cytic infiltration in the dermis and subcutaneous tissue.Immunohistologically,the tumor cells were positive for cytoplasmic CD3 around the nuclei,for CD56,CD45RO and T cell intracellular antigen-l,and partly for CD30,CD8 and Ki67.Epstein-Barr virus-encoded nuclear RNA was positive with in situ hybridization. TCR?-2 gene rearrangement was positive in these tumor cells.A diagnosis of hydroa vacciniforme-like primary cutaneous NK/T-cell lymphoma was made.Therefore,this is a case report of hydroa vaccini- forme-like primary cutaneous NK/T-cell lymphoma with primary involvement in the skin;the condition was slowly progressive over 51 months.

Abstract?AlM: To compare the in- the- bag lOL stability of different size of continuous curvilinear capsulorhexis ( CCC) in super high myopic eyes with cataract underwent phacoemulsification.?METHODS: A total of fourteen cataract patients with bilateral super high myopia were included, Phaco+lOL implantation were performed on both eyes, one eye was randomly classified into 5mm diameter CCC observation group, the fellow eye was 6mm diameter CCC observation group. Cataract extraction combined with in-the-bag intraocular lens implantation ( lOL ) with the type of hydrophilic acrylic aspheric intraocular lens ( MCX11 ) by well experienced surgeon. The operation was running smoothly, the next day after operation, all patients were confirmed by lmage-pro plus6. 0 image analysis software for the measurement of main meridian sac diameter with target capsulorhexis diameter no more than ±0. 2mm. Slit lamp examination of lOL shape and position, changes of anterior capculorhexis edge, refraction, anterior chamber depth was measured and observed of all eyes after operation 1wk;1, 3, 6mo.? RESULTS: Compared with postoperation 1wk, the former sac diameter of two groups were slightly smaller at postoperation 1mo, with no statistically significant difference between two groups. 5mm diameter CCC observation group had slightly hyperopic shift in follow-up 1-3mo, 6mm diameter CCC observation group had hyperopic shift in follow-up 1mo, and getting stable after 1mo. Refraction change was related to anterior chamber depth changes. 5mm diameter CCC observation group had 3 minor loop folding in follw-up 3mo.?CONCLUSlON:Relatively smaller continuous curvilinear capsulorhexis in super high myopic eyes underwent cataract surgery may cause a tendency of uneven construction or effective lens position change of in-the-bag lOL. Unusual refraction change or shift after operation 1mo could suggest instability of lOL, early noticing or interruption could prevent further complications.

OBJECTIVETo explore the effect of Bushen Tiaojing Recipe (BTR) on the quality of oocytes, reproductive hormones, and the expression of bone morphogenetic protein-15 (BMP15) of in vitro fertilization-embryo transfer (IVF-ET) patients.
METHODSSixty infertility patients who prepared for IVF-ET were assigned to two groups according to the treatment order, the treatment group [20 cases, treated with BTR + controlled ovarian hyperstimulation (COH)] and the control group (treated with COH alone, 40 cases). Age, the time limit for infertility, basal follicle-stimulating hormone (bFSH) concentration, usage days and the dosage of gonadotropins (Gn), serum levels of estradiol (E2), luteotropic hormone (LH), and progesterone (P) on the HCG injection day, the number of retrieved occytes, the fertilization rate, the number of embryos, the high quality embryo rate, and the clinical pregnancy rate were compared. Concentrations of follicle-stimulating hormone (FSH), LH, E2, testosterone (T), and P in the follicular fluid were detected via chemiluminescence microparticle immunoassay. The mRNA and protein expression of BMP-15 in mature granulosa cells was detected by real-time fluorescent PCR and Western blot.
RESULTSThirty-two patients were pregnant and the total pregnancy rate was 53.3%. Of them, 19 were pregnant and the total pregnancy rate was 47.5% in the control group, while 20 were pregnant and the total pregnancy rate was 65.0% in the treatment group. But there was no statistical difference between the two groups (P > 0.05). Compared with the control group, the Gn dosage was lower and the high quality embryo rate was higher in the treatment group, showing statistical difference (P < 0.05). There was no statistical difference in serum concentrations of E2, LH, or P on the HCG injection day, the number of retrieved oocytes, or the fertilization rate (P > 0.05). Compared with the control group, FSH concentrations in the follicular fluid were significantly lower and LH concentrations were significantly higher in the treatment group (P < 0.05). The LH concentrations in the follicular fluid were significantly higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).There was no statistical difference in E2, T, or P concentrations (P > 0.05). The mRNA and protein expression of BMP-15 in granulosa cells was higher in the treatment group than in the control group (P < 0.05). It was also higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).
CONCLUSIONDuring the IVF-ET process, BTR could elevate the quality of oocytes, and increase the sensitivity of ovarian follicles to exogenous Gn, which was correlated with the mRNA and protein expression of BMP-15 in granulosa cells, and changing concentrations of FSH and LH.
