Objective To investigate the effect of immunoglobulin G (IgG) in bullous pempbigoid (BP) blister fluid on the secretion of chemokines by human keratinocytes. Methods IgG was obtained from the blister fluid of patients with bullous pemphigoid and sera of normal human controls, then purified by sequential precipitation with caprylic acid and ammonium sulfate. The immunological activity of blister fluid was tested before and after the purification by BP180 ELISA kit. Keratinocytes were isolated from the foreskin tissue of yong adults, and subjected to primary culture. After 3 passages, the primary keratinocytes were harvested and subcultured in the presence of purified IgG of 0.5, 1, 2, 4 and 8 g/L, respectively, for 24 hours, or IgG of 4 g/L for 3, 6, 12, 24 hours, respectively, followed by the detection of levels of eotaxin, monocyte chemoattractant protein (MCP)-1 and interleukin (IL)-8 in the supemate of keratinocytes by ELISA. Results The valence of IgG remained unchanged after the purification with caprylic acid and ammonium sulfate. Compared with IgG from the sera of normal controls, that from bullous pemphigoid blister fluid sig- nificantly enhanced the secretion of IL-8 by keratinocytes in a time- and dose-dependent manner (both P < 0.01 ). Neither eotaxin nor MCP-1 was detected in the supemate of control IgG-treated, BP IgG-treated or untreated keratinocytes. Condusions The IgG in BP blister fluid has been proved to stimulate the secretion of IL-8 by cultured human keratinocytes, which may be involved in the pathogenesis of BP.

OBJECTIVE: Understand the changes before and after treatment in patients with severe OSAHS serum S100β protein, NSE levels and cognitive function. To investigate the molecular mechanisms of cognitive dysfunction in patients with severe OSAHS. Serum S100β protein, NSE levels and cognitive function were examined before and after the therapy. METHOD: Select one hundred patients diagnosed as severe OSAHS were included, by polysomnography (PSG) diagnosis of severe OSAHS patients. Determination of serum S100β protein, and NSE levels and theat the same time be MoCA score were checked at after the day after admission, CPAP treatment for the 7th days after CPAP treatment and the 90th day after, comprehensive treatment in these patients for 3 months. Assessment of severe OSAHS patients with serum S100β protein, NSE basic level and MoCA score situation. Comparison of three groups serum S100β protein, NSE levels and MoCA score changes. Serum S100β protein, NSE detection assay (ELISA) method using enzyme-linked immunosorbent. RESULT: (1) Severe OSAHS patients with serum S100β protein, and NSE levels in severe OSAHS patients were positively correlated with AHI, but negatively correlated with lowest oxygen saturation (LSaO2); (2) MoCA score in patients with severe OSAHS was significantly negatively correlated with AHI, but positively correlated with LSaO2; (3) S100β protein, NSE levels were negatively correlated with MoCA score; (4) Compared with admission, serum S100β protein, and NSE levels in these patients have declined after 7 days CPAP therapy, compared with admission the difference was statistically significant (P < 0.05). After 3 months of comprehensive treatment, patients' serum S100β protein and, NSE levels were significantly decreased, compared with the admission and the 7th days after CPAP treatment. The difference was statistically significant (P < 0.05). (5) After CPAP treatment for 7 days, the MoCA scores were slightly higher, but have there was no statistically significant difference compared with the admission (P > 0.05). After 3 months of comprehensive treatment, MoCA score improved significantly, compared with the admission and 7 days after CPAP treatment the difference was statistically significant (P < 0.05). CONCLUSION Comprehensive treatment can reduce serum S100β protein, and NSE levels, and improve MoCA score. Disease severity in patients with OSAHS have a correlation some relative.with the serum S100β protein, NSE levels and MoCA score. Long-term hypoxemia and the structure of sleep disorders may be the cause of elevated serum S100β protein, NSE levels elevated and causes of cognitive dysfunction. Comprehensive treatment can improve patient hypoxemia, correct disorders of sleep structure ,and can improve cognitive function and to improve the quality of life of patients.

Objective To investigate the characteristics and treatment effects in patients with spinal fractures associated with dural tears.Methods A retrospective analysis was made on 185 patients with spinal fractures presenting to hospital from February 2013 to February 2015.There were 103 males and 82 females,aged 17-73 years (mean,58 years).Causes of injury were high falls in 72 patients,traffic collisions in 58,hitting by heavy objects in 41,ground-level falls in 12,and collision events in two.Cervical spine fractures were seen in 65 patients,thoracic vertebra fractures in 51,and lumbosacral vertebral fractures 69.Neurologic deficit was assessed using the American Spinal Injury Association (ASIA) score,including grade A in 24 patients,grade B in 22,grade C in 26,grade D in 37 and grade E in 76.Eighty patients were managed by simply anterior surgery,97 by posterior surgery,and eight by anterior-posterior surgery.Twenty-one patients were found with dural tears (group A) and 164 patients without dural tears (group B).Incidence of dural tears in cervical,thoracic and lumbosacral vertebral fractures were recorded and compared.Preoperative neurologic deficit,laminar fracture and spinal canal encroachment rate were compared between groups.Neurological function and complications associated with dural repair were detected.Results In group A,ten patients were rated ASIA grade A,five grade B,three grade C,one grade D and two grade E.In group B,14 patients were rated ASIA grade A,17 grade B,23 grade C,36 grade D and 74 grade E.Group A accounted for 11％ (7/65) of cervical,10％ (5/51) of thoracic,and 13％ (9/69) of lumbosacral spine fractures (P ＞ 0.05).Nineteen patients (91％) in group A were complicated with neurological deficit,compared to ninety patients (54.9％) in group B (P ＜ 0.01).Eighteen patients (86％) in group A had laminar fractures,compared to fifteen patients (9.1％) in group B (P ＜ 0.01).In group A,rate of spinal canal encroachment was (62.3 ± 12.1)％ and 17 patients (81％) showed spinal canal encroachment of greater than 50％.While in group B,rate of spinal canal encroachment was (36.2 ± 15.6)％ and 25 patients (15.2％) showed spinal canal encroachment of greater than 50％ (P ＜ 0.01).For dural tears in group A,11 patients were treated by direct suturing,four by thoracolumbar fascia repair,three by artificial dural coverage and three by fibrin glue sealing.In group A,19 patients were followed up and one of them presented persistent cerebral spinal fluid leak that necessitated an irrigation and debridement to cure.ASIA score was improved from grade A to B in two patients,grade B to C in one,grade C to D in one and grade D to E in one at the final follow-up.Conclusions Majority patients with spinal fractures associated with dural tears exist severe neurologic deficit,spinal canal encroachment and laminar fractures.Incidence of dural tear in cervical,thoracic and lumbosacral vertebral fractures is similar.Incidence of complications related to dural tear repair is low,but the neurological function recovery is poor after operation.

Objective To fabricate a novel tissue-engineered cartilage with adipose-derived stem cells (ADSCs) seeded on the chitosan hydrogel scaffold to repair articular cartilage defect.Methods Adipose tissue and costal cartilage were harvested from New Zealand rabbits,and ADSCs in passage one and chondrocytes were obtained after the samples were digested and cultured in vitro.ADSCs were digested,suspended,seeded onto the sterile chitosan gel,and cultured in vitro for 1 week to fabricate the tissue-engineered cartilage.The defects were respectively filled with the tissue-engineered cartilage (composite group),chondrocyte suspension (cell group),chitosan gel (material group) and nothing at all (control group).At postoperative 12 weeks,cartilage repair was evaluated using the gross examination,histological staining,immunohistochemical staining and international cartilage repair society (ICRS) histological score.Results Effect of cartilage repair in composite group was significantly better compared to other groups.The regenerated tissue in composite group seemed tightly bound in normal tissue,with similar structure and extracellular matrix secretion.ICRS histological score in composite group was (13.89 ± 0.14) points,which differed significantly from (7.06 ± 0.19) points in control group,(7.14 ± 0.22) points in cell group and (7.46 ± 0.26) points in material group (P ＜0.01).Conclusion The tissue-engineered cartilage with ADSCs seeded onto the chitosan hydrogel is effective for repair of articular cartilage defect.

Objective To determine the feasibility and safety of transprostatic utricle seminal vesiculoscopy in the treatment of hemospermia. Methods Totally 11 patients with hemospermia, mean age of (46.6 ± 3.5) years, ranging from 38 to 68 years, for 3 months admitted from September 2012 to August 2015 were enrolled, Their main manifestations were hemospermia. Painful ejaculation was observed in 7 patients, and perineal and testicular pain occured in 4 patients. They all underwent transprostatic utricle seminal vesiculoscopy, and then were followed up for 3 to 6 months. Results Ten patients were operated successfully, but 1 patient failed. The operation revealed that the causes of hemospermia were seminal vesiculitis in 8 cases, seminal vesiculitis accompanied with seminal calculi in 2 cases, and ejaculatory duct cyst in 1 case. Operation time was (29.2 ± 3.2) min ( ranging from 25 to 37 min) , and hospital stay was 2 d ( from 2 to 4 d). Hemospermia disappeared in 10 patients within 1 month of surgery, and hemospermia recurrence was observed in 1 patient within 6 months. The patient was treated with transprostatic utricle Holmium laser incision, then hemospermia was dispeared,Two cases of postoperative epididymitis were cured after one week of antibiotic treatment. Conclusions Seminal vesiculoscopy is a safe and effective to treat hemaospermia.

Objective To investigate the value of ultrasound elastosonography in the diagnosis of liver fibrosis. Methods One hundred and twenty patients with chronic hepatitis B were examined by ultrasound elastosonography and given elasticity scores,the correlation coefficient between the elasticity scores and the histologic fibrosis stage was evaluated and its difference in the diagnosis of liver fibrosis was compared.

OBJECTIVETo study the effects of inhalation enflurane (Enf) before aortic clamping on myocardial reperfusion injury in cardiac surgery with cardiopulmonary bypass (CPB).

METHODShirty patents undergoing selective cardiac valve replacement were randomly allocated to three groups. Group I and group II inhaled 1.0 MAC and 0.5 MAC Enf before clamping aorta, respectively. Group III was the control group interval administration with Fentanyl.

RESULTSImmediately upon aortic clamp release (T2), the value of CK-MB, MDA and SOD of all the groups was significantly increased, however,their concentration did not peak significantly until T3 and T4(10 and 30 min after clamp aorta release). The levels at 60 min (T5) and 24 hours (T6) aorta were lower than T4 but still higher than T(0). At T3 and T4, CK-MB levels in group I were significantly higher than those in II and III groups (P=0.0220, 0.0108 and 0.0202, 0.0295). At T6, the CK-MB level of group II was significantly higher than that of group III (P<0.0001). At T4 and T5, the MDA value of group I was higher than that of group II (P=0.0060 and 0.0364). Meanwhile, the SOD level in group I was also higher than that of group II and group III at the T4 point (P<0.0001 and 0.0084). There was a correlation between the CK-MB value and the aorta clamping time,correlation coefficient range being 0.55 - 0.81,(P<0.05). However, there was no correlation between the CK-MB and MDA, SOD.

CONCLUSIONThere is ischemia reperfusion injury during cardiac surgery CPB with the increase of OFR production and elevation of the antioxidant reserve. Inhalation of large dose of enflurane may result in increased myocardial ischemia reperfusion injury manifested by elevated levels of myocardial enzymes and OFR production.

Objective To observe the effect of T-2 toxin on growth and development of rat epiphyseal plate of left knee and metaphyseal bone of femur and tibia in normal and low nutritional status, to find out possible pathogenic factors of Kashin-Beck disease and provide experimental basis for early intervention. Methods Ninety 3-week-old Wistar rats, weighing 60 - 70 g, were randomly divided into three groups: control group(general feed), T-2 toxin + general feed group, T-2 toxin + low nutrition feed group, thirty rats in each group with equally sex ratio. T-2 toxin (1.0 mg/kg) was administered orally 5 times a week via a gavage needle for 4 weeks. The change of hair, activity and body weight was observed. After 1, 2, 4 weeks, the epiphyseal plate of left knee and metaphyseal bone of femur and tibia (including distal femur and proximal tibia) were collected. Specimens were processed with HE and Masson staining. The morphology of chondrocytes and matrix collagen content in epiphyseal plate was observed. Trabecular bone volume fraction in tibial metaphyseal bone was analyzed by Image-Pro Plus 6.0 software. Results In the control group, rats were in good movement and hair with light, but in T-2 toxin + general feed group and T-2 toxin + low nutrition feed group, rats were found with reduced activities and hair with dark color. Body weights(g) of the control group, the T-2 toxin + general feed group and the T-2 toxin + low nutrition feed group were 81.0 ± 6.2, 79.0 ±5.1, 77.0 ± 7.5, respectively, by the end of first week; 101.8 ± 6.7, 97.0 ± 6.8, 93.0 ± 5.3, respectively, by the end of second week; 151.1 ± 15.7, 126.5 ± 11.9, 106.5 ± 11.5, respectively, by the end of fourth week. There was significant difference in groups by second week and the fourth week (F = 9.72, 41.65, all P ＜ 0.05 ). There was significant difference among multi-groups by the fourth week(all P ＜ 0.01 ). Under light microscope, at the second weeks, coagulative necrosis of chondrocytes was found in hypertrophic zone in the two groups with T-2 toxin; at the fourth weeks, cell necrosis increased. Masson staining showed collagen staining in the two groups with T-2 toxin significantly turned to clear pale coloration, indicating that the collagen matrix was significantly reduced. Image analysis showed there was significant difference in groups at the second and fourth week(F= 9.72, 41.65, all P＜ 0.05)in tibial metaphyseal trabecular bone volume fraction. There was significant difference between T-2 toxin + low nutrition feed group[(0.55 ± 0.12)％, (0.21 ± 0.0)％] and control group[(0.67 ± 0.09)％, (0.51 ± 0.14)％] by the second and fourth week(all P ＜ 0.01 ). Conclusions Under normal nutritional status, T-2 toxin can induce hypertrophic epiphyseal cartilage necrosis, collagen content decreased in epiphyseal plate, metaphyseal trabecular bone formation disorders; in the low nutritional status, T-2 toxin can lead to rat epiphyseal necrosis and significant metaphyseal bone disorder, but whether the performance is related to Kaschin-Beck disease needs to be studied further.
