Henoch-Schonlein purpura(HSP)is the most common vasculitic disease affecting children,which is a multisystem immunoglobulin A mediated vasculitis with a self-limited course affecting the skin,joints,gastrointestinal tract and kidneys.Antiphospholipid syndrome(APS)is a systemic autoimmune disorder characterized by a combination of arterial or venous thrombosis and recurrent fetal loss,accompanied by elevated titers of antiphospholipid antibodies.Both HSP and APS are multisytem diseases and are thought to result from immunologically mediated processes.It was known that APS can associated with HSP,but the relationship between the 2 diseases is unclear.The literature on HSP associated with APS was reviewed and the possible mechanism was analyzed.

Objective To explore the effective therapeutic methods for hepatolithiasis.Methods We retrospectively analyzed the clinical material of 178 hepatolithiasis patients who underwent surgical therapy.Among the 178 patients,107 patients were treated with T-tube drainage(including 7 patients with left hepatic lobe or quadlrate lobe resection),and 71 patients were treated with bile duct-intestinal anastomosis(including 11 patients with left hepatic lobe or quadrate lobe resection).Results Recurrence rate of postoperative angiocholitis in the two groups was 49.5 % and 24 % respectively,and the reoperation rate was 28.7 % and 8 % respectively.Conclusions The key to prevent recurrent angiocholitis and reduce the reoperation rate is to relieve biliary tract stricture,remove the focus of infection and provide unobstructed bile duct drainage.

AIM:To observe the clinical effect of femtosecond laser assisted penetrating keratoplasty.
METHODS: Twenty-four cases ( 24 eyes ) with corneal lesions were performed with femtosecond laser assisted penetrating keratoplasty. Preoperative and postoperative endothelial cell density and visual quality were compared.RESULTS: One week after operation, corneal grafts were clear in 21 eyes (87. 5%), mild cloudy in 3 eyes (12.5%);visual acuity ≥0. 5 in 18 eyes (75. 0%), 0. 2 ~0.4 in 6 eyes ( 25. 0%). After 3mo the mean corneal astigmatism was 2. 16±0. 21D ( range 2. 25 ~ 3. 09D). Compared to conventional penetrating keratoplasty which mean corneal astigmatism was average 3. 67±0. 38D after operation, there was significant difference between two groups ( P< 0. 05 ). There were significant differences between preoperative and postoperative visual acuity and astigmatism (both P<0. 05).
CONCLUSION: Femtosecond laser assisted penetrating corneal transplantation operation can improve patient's visual quality. And compared to traditional penetrating keratoplasty astigmatism decreased significantly, incision can be made in individual shape more precisely and neatly.

Objective To evaluate the cost-effectiveness of early enteral nutrition (EEN) in elder patients undergoing gastrectomy for gastric carcinoma. Methods An outcome-based retrospective review of 52 patients who had undergone gastrectomy for gastric carcinoma between July 1999 and June 2002 was performed .There were 27 patients in the EEN group, and 25 in the TPN group. Results The mean postoperative hospital days of the EEN group was significantly less than that of the TPN group (16.3 d vs. 21.3 d, t =4.6814, P

Objective To evaluate the efficacy and safety of ustekinumab in the therapy of plaque psoriasis.
Methods Literatures published up to November 2013 were collected from Cochrane library, MEDLINE, and PubMed which were related with ustekinumab for plaque psoriasis. The efficacy was estimated using relative risk of Psoriasis Area and Severity Index (PASI) 75 response rate at the week 12 endpoint in clinical trials, and adverse effects were also analyzed. Meta-analysis was carried out by using Review Manager 5.1.
Results Six randomized control trials consistent with the inclusion criteria were selected and reviewed. Ustekinumab 45 mg group and 90 mg group could get better therapeutic effect compared with the placebo group (all P<0.00001). Furthermore, ustekinumab 90 mg group was more effective than ustekinumab 45 mg group (P=0.01). Adverse effects in the 6 trials were mentioned including headache, upper respiratory tract infection, nasopharyngtis, infection, serious infection, cardiovascular events, and malignant tumors. There were no statistically significant differences of these adverse effects among three groups (all P>0.05), except that infection rate in ustekinumab 45 mg group was higher than the placebo group (P=0.02).
Conclusions Ustekinumab is an effective and safe therapeutic method for plaque psoriasis. However, further longer time analysis of safety is needed.

Objective To investigate the expression and significance of CDK4 and cyclin D1 in gastric carcinoma,and to discuss their correlation with WHO histological classification,TNM stages and lymph node metastasis.Methods Forty paraffin wax specimens from patients with gastric carcinoma were collected and expression of CDK4 and cyclin D1 proteins were detected by immunohistochemistry.Results Immunohistochemistry demonstrated that the positive rates for CDK4 and cyclin D1 protein were 65% and 55%,respectively.There was positive correlation between CDK4 and cyclin D1 proteins(P0.05).Conclusion CDK4 and cyclin D1 proteins are frequently overexpressed in gastric carcinoma and there is a positive relationship between the two proteins,which may be involved in the development of gastric carcinoma.

The spores suspension of Streptomyces roseosporus D-38 irritated with 20mW He-Ne laser for 20 min were incubated on G1 medium plates containing 1. 9?g/mL of streptomycin. Ten percent of mutants increased the potency of daptomycin by streptomycin-resistance method, including the mutant LC-54, which could produce daptomycin 81. 2 mg/L, which was 39% higher than that of the beginning strain by flask fermentation.

Hydrogen is an ideal energy due to its high conversion efficiency, recyclability and nonpolluting nature. Compared with conventional methods, biological hydrogen production process is found to be less energy intensive and more environmental friendly, and nowadays more and more attentions are being paid on its fermentative way. A survey of fermentative bio-hydrogen production process was provided, followed by its new approaches in the future development.

BackgroundThe meibomian gland carcinoma is an eyelid malignant tumor with a domestic incidence after basal cell carcinoma.Meibomian gland carcinoma is not sensitive to radiation therapy and chemotherapy,and the related factors with its recurrence and metastasis are rarely reported.ObjectiveThis study was to investigate the clinical and pathologic features of meibomian gland carcinoma with multiple operations and the effectiveness of histologically controlled excision.MethodsThe clinical data and the histopathologic sections of 34 cases of the meibomian gland carcinoma diagnosed by pathology were retrospectively analyzed at Zhongshan Ophthalmic Center in September 2003 to April 2011,and the treating effectiveness of histologically controlled excision was evaluated. ResultsIn this group of cases,the appearing rate of the meibomian gland carcinoma was resemble in both lateral eyes.A higher morbidity was on the upper eyelid (26/34,76.5％) and then the lower eyelids (5/34,14.7％ ) and both (3/34,8.8％).The average ages of these cases were 57.5 years old.Sixteen of 21 misdiagnosed cases were identified as chalazion at the first visit,and no histopathological examination was performed in 11 cases after initial operation.Twenty-six cases(76.5％ )were identified as meibomian gland carcinoma in initial histopathologic diagnosis.Two cases had histologically controlled excision and 16 cases had simple excision while 16 cases had chalazion enucleation in the first operation.All the patients had histologically controlled excision in Zhongshan Ophthalmic Center with 58.8％ of the patients having pagetoid invasion.Sixteen cases were followed up for 5 months to 8 years after histologically controlled excision,in which none died of recurrence and metastasis of meibomian gland carcinoma.No significant differences were found in the pathological feature between 16 lost patients and 18 followed-up patients(P ＞ 0.05 ).Conclusions Misdiagnosis of meibomian gland as chalazion is a main cause of repeat operations of meibomian gland carcinoma.Histologically controlled excision is a feasible therapy for the recurrence and metastasis of meibomian gland carcinoma.
