Extramedullary plasmacytoma (EMP) is a rare tumor characterized by proliferation of monoclonal plasma cells,often occurs in the head and neck,followed by gastrointestinal and skin.Diagnosis is based on biopsy,which is the only accurate and reliable method.EMP is needed to discriminate with similar diseases.Radiotherapy is the preferred treatment method of EMP,because it has a higher radiation sensitivity.Sometime we can choose comprehensive treatment because of illness need.Hematopoietic stem cell transplantation is not as the preferred treatment option because of transplant rejection.

Previous studies have found that 40% of patients with acute ST-segment elevation myocardial infarction(STEMI) combine with multiple vascular lesions(MVD), which is known as one of the main risks for poor prognosis in patients with myocardial infarction.However,the management of non-IRA remains controversial, and there is no consensus on the management of non-IRA in STEMI. FFR could be a new criteria in non-IRA PCI,since it could evaluate coronary flow reserve more intuitively than coronary angiography alone.

Migration of adventitial fibroblasts (AF) is involved in the neointimal formation which is one of the common pathological processes in several vascular diseases. The observation of whether the migratory response of AF from hypertensive animal is different from that of controls may provide an explanation of vascular remodeling in hypertension. We examined whether there is any difference between the migratory activity of AF derived from spontaneously hypertensive rat (SHR) and that from their normotensive counterpart Wistar-Kyoto rats (WKY). In addition, the role of osteopontin (OPN) in cell migration was also examined. Primary cultures of aortic adventitial fibroblasts were derived from SHR and age-matched WKY. Migration of fibroblasts was determined with the Transwell method. The mRNA expression level of OPN was measured by a real-time quantitative PCR. When compared with WKY-derived cells, migration of adventitial fibroblasts from SHR exhibited an increased response when stimulated by 10% serum (cell number per field 35.20+/-5.26 vs 22.2+/-3.27, p<0.05). Chemotaxis induced by 10 ng/ml bFGF showed a similar difference (cell number per field 30.23+/-4.54 vs 19.20+/-4.47, p<0.05). We also found that SHR-derived fibroblasts expressed a higher level of OPN mRNA than the cells from WKY (1863.23+/-43.91 vs 326.24+/-68.29, p<0.01). To verify if OPN is associated with the enhanced migratory ability in AF from SHR, we designed the antisense oligonucleotide of OPN. The results showed that the antisense OPN oligonucleotide significantly inhibited AF migration (cell number per field 38.60+/-5.98 vs 26.61+/-3.84, p<0.05), while sense and mismatch OPN oligonucleotide had no effect on cell migration. Therefore, the migration of adventitial fibroblasts appeared to be enhanced in cultures derived from SHR. OPN might be involved in the difference observed.

Long-segment lichen sclerosus (LS) urethral stricture is a challenge for urologists. Limited data are available for surgeons to make a surgical decision between Kulkarni and Asopa urethroplasty. In this retrospective study, we investigated the outcomes of these two procedures in patients with LS urethral stricture. Between January 2015 and December 2020, 77 patients with LS urethral stricture underwent Kulkarni and Asopa procedures for urethroplasty in the Department of Urology, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine (Shanghai, China). Of the 77 patients, 42 (54.5%) underwent the Asopa procedure and 35 (45.5%) underwent the Kulkarni procedure. The overall complication rate was 34.2% in the Kulkarni group and 19.0% in the Asopa group, and no difference was observed ( P = 0.105). Among the complications, no statistical difference was observed in the incidence of urethral stricture recurrence ( P = 0.724) or glans dehiscence ( P = 0.246) except for postoperative meatus stenosis ( P = 0.020). However, the recurrence-free survival rate between the two procedures was significantly different ( P = 0.016). Cox survival analysis showed that antiplatelet/anticoagulant therapy use ( P = 0.020), diabetes ( P = 0.003), current/former smoking ( P = 0.019), coronary heart disease ( P < 0.001), and stricture length ( P = 0.028) may lead to a higher hazard ratio of complications. Even so, these two techniques can still provide acceptable results with their own advantages in the surgical treatment of LS urethral strictures. The surgical alternative should be considered comprehensively according to the patient characteristics and surgeon preferences. Moreover, our results showed that antiplatelet/anticoagulant therapy use, diabetes, coronary heart disease, current/former smoking, and stricture length may be contributing factors of complications. Therefore, patients with LS are advised to undergo early interventions for better therapeutic effects.

OBJECTIVETo evaluate and compare standard sperm parameters and sperm DNA fragmentation in seminal ejaculates from men whose partners had a history of recurrent pregnancy loss (RPL) and a control group of men who had recently established their fertility.

METHODSSemen samples from 85 patients with a history of RPL and 20 men with proven fertility were analyzed according to World Health Organization guidelines. Sperm DNA fragmentation was detected by sperm chromatin dispersion test (SCD).

RESULTSA significant difference (P< 0.05) was observed in sperm motility but not other parameters between the two groups. The mean number of sperm cells with fragmented DNA, represented as DNA fragmentation index, was significantly increased in the RPL group [(34.99± 14.62)%] compared with controls [(10.82± 4.80)%].

CONCLUSIONThis study has indicated that sperm from men with a history of RPL have a higher incidence of DNA damage and poor motility compared with fertile males.

OBJECTIVETo evaluate the exploratory development of bone graft by titanium mesh with bone allograft in treatment of cervical spinal tuberculosis.

METHODSThirty two cases of cervical spinal tuberculosis treated with anterior radical debridement, decompression and inter fixation from January 2002 to January 2007 were included (at least two years follow-up). 18 male and 14 female, age from 18 to 72, mean 41.3 years old. 0.5 - 15.0 months before visit, mean 6.9 months. There were 13 cases in initial treatment group and 19 cases in retreatment group. All cases were divided into two groups (group A and group B) by resource of bone graft. Group A, titanium mesh with bone allograft, 17 cases. Group B, autograft with ilium, 15 cases. Operation time, blood loss, curing conditions, cervical curvature (absolute rotation angle, ARA), function of spinal cord and the rate for bone graft fusions in two groups were compared. The mean follow-up was 3.5 years (range 2 - 5 years).

RESULTSThe primary healing rate of incisions was 93.8% (30/32), and total healing rate was 96.9% (31/32). There were no significant differences in operation time or in blood loss between two groups (P > 0.05). Operation time and blood loss, 72 min/121 ml in group A and 90 min/198 ml in group B, there were significant differences between two groups (P < 0.05). In each group, there were significant differences in the function of spinal cord between preoperative and immediately post operative, between preoperative and follow-up, and between immediately post operative and follow-up (P < 0.05), and there were significant differences in ARA between preoperative and immediately post operative, and between preoperative and follow-up (P < 0.05), and there were no significant differences between immediately post operative and follow-up (P > 0.05). On preoperative, immediately post operative and follow-up, there were no significant differences in the function of spinal cord or in ARA between two groups (P > 0.05).

CONCLUSIONFor cervical spinal tuberculosis followed by effective individual chemotherapy, a good effect can be obtained by treated with radical debridement and bone allograft with titanium mesh.

OBJECTIVETo compare the differences on onset timing of acute ST segment elevation myocardial infarction (STEMI) in young and aged patients.

METHODSThe exact onset time of symptoms was obtained from 1024 consecutive patients with STEMI admitted to our hospital between January 2000 and May 2010. Patients were classified as the middle-aged group [< 65 years old, mean (52.2 ± 8.0) years, n = 536] and old group [≥ 65 years old, (72.2 ± 5.5) years, n = 488], the difference of the onset months, weeks, weekdays and hours between two groups was compared.

RESULTSThe high onset timing of STEMI in middle-aged group was October and February, Friday, Saturday and Wednesday, at 10 A.m. and 10 P.m. The high onset timing of STEMI in old group was October, January and March, Friday, Sunday and Monday, at 6 A.m. and 2 A.m. The incidences of STEMI in the old group were significant higher than in the middle-aged group in March (11.89%), on Sunday (15.97%) and Monday (17.42%), at 6 A.m. (6.35%) and 2 A.m. (5.74%) (all P < 0.05) while the onset rate was significant higher in February (9.89%), On Saturday (16.98%), At 8 P.m. (4.86%) and 10 P.m. (5.78%) in the middle-aged group than old group (all P < 0.05).

CONCLUSIONThe onset timing of STEMI in old patients was significant different from the middle-aged patients suggesting the onset timing of STEMI changes with aging.

To establish the water dynamics model for drying process of Angelicae Sinensis Radix, the Weibull distribution model was applied to study the moisture ratio variation curves, and compared the drying rate and drying activation energy with the drying methods of temperature controllable air drying, infrared drying under different temperatures (50, 60, 70 degrees C). The Weibull distribution model could well describe the drying curves, for the moisture ratio vs. drying time profiled of the model showed high correlation (R2 = 0. 994-0. 999). The result proved that the drying process of Angelicae Sinensis Radix belonged to falling-rate drying period. For the drying process, the scale parameter (a) was related to the drying temperature, and decreased as the temperature increases. The shape parameter (β) for the same drying method, drying temperature had little impact on the shape parameter. The moisture diffusion coefficient increase along with temperature increasing from 0.425 x 10(-9) m2 x s(-1) to 2.260 x 10(-9) m2 x s(-1). The activation energy for moisture diffusion was 68.82, 29.60 kJ x mol(-1) by temperature controllable air drying and infrared drying, respectively. Therefore, the Weibull distribution model can be used to predict the moisture removal of Angelicae Sinensis Radix in the drying process, which is great significance for the drying process of prediction, control and process optimization. The results provide the technical basis for the use of modern drying technology for industrial drying of Angelicae Sinensis Radix.
