AIM:To evaluate the feasibility and advantages of two-port 27-gauge pars plana vitrectomy for treatment of recurrent retinal detachment in silicone oil dwelling eyes.METHODS:A retrospective study.Two-port 27-gauge pars plana vitrectomy was performed in 7 eyes with recurrent retinal detachment without remove of silicone oil.Proliferative membrane peeling, endolaser treatment, and drainage of subretinal fluid were performed.Scleral bulking was performed if necessary.RESULTS:Sucessful retina re-attachment was accomplishied in all eyes.No visually significant intraoperative complication occurred.All eyes expericend quick recoveray of visual acuity and mild postoperative irritation.One eye developed a recurrent inferior retinal detchment in 20d after the surgery using non-remove technique, and recovered after conventional silicone oil removal and retinal reattachment surgery.CONCLUSION:Two-port 27-gauge pars plana vitrectomy is an efficacious (and potentially cost-efficient) method to treat early stage recurrent retinal detachment in silicone oil dwelling eyes.

OBJECTIVETo apply single nucleotide polymorphism (SNP) microarray for delineation of small supernumerary marker chromosome (sSMC) in two newborns.

METHODChromosome karyotyping was performed on newborns who were born in Jan. 2013 and Jan. 2014 in Haidian Maternal and Child Health Hospital because of the abnormalities found in pregnancy checkups. SNP microarray analysis was carried out on 2 newborns with de novo sSMCs (one was mos 47,XY, + mar[45]/46,XY[5] and the other was mos 47, XY, + mar [30]/46, XY [20]), which could not be determined by conventional banding techniques. Genomic DNA was extracted from cord blood samples, amplified, tagged and hybridized following the manufacturer' s protocol. Data were collected and analyzed.

RESULTThere was a 78. 6 Mb duplication in chromosome 8 for Newborn A, which was associated with 8p22 duplication syndrome; and a 32. 7 Mb duplication in chromosome 13 for Newborn B, which was not yet reported definitely as pathogenic. The newborn A was identified with agenesis of the corpus callosum, obvious right eyelid drooping, the onset of low muscle tone and mental developmental lag behind their peers, while the newborn B had normal findings on physical and mental evaluation.

CONCLUSIONSNP-array can identify sSMCs of newborns at the DNA level, and can be used as an important supplement to the conventional karyotype analysis, but the pathogenicity of positive outputs need further verification.

AIM: To study the effects of CIK cocultured with DC that pulsed with RCC antigen on renal carcinoma cells.METHODS: DC and CIK cells were generated respectively by cytokines from PBMC of healthy blood donor.Cell surface markers were analyzed by flow cytometry.Then CIK were cocultured with autologous DC that was(or not) pulsed with RCC antigen(786-0 cells).Cytotoxic activity against 786-0 or PC3 cells was measured by MTT assay under three different conditions: CIK cocultured with DC which was pulsed with 786-0 antigen(group A);CIK cocultured with DC which is not pulsed with 786-0 antigen(group B);CIK without DC(group C).RESULTS: The cytotoxic activity of three groups against 786-0 cells was(70.64?8.26)%,(53.40?7.33)%,(46.64?6.01)%,respectively(E/T=(20∶1)).Significant differences between group A and group B or between group A and group C were observed(P

OBJECTIVETo observe the effects of Danlou Tablet (DT) on inflammatory reaction, and expressions of lipoprotein-associated phospholipase A2 (LP-PLA2), secretory phospholipase A2 (sPLA2), and to analyze potential mechanisms.

METHODSForty male Wistar rats were randomly and equally divided into five groups, i.e., the normal control group, the model group, the Western medicine (WM) group, the low dose DT group, the high dose DT group, 8 in each group. Rats in the normal control group were fed with basic forage for 12 successive weeks, while AS rat model was established in rats of the other four groups by feeding high fat and sugar forage plus intraperitoneal injection of vitamin D₃. Normal saline, atorvastatin calcium suspension (at the daily dose of 1.8 mg/kg), low dose DT suspension (at the daily dose of 450 mg/kg), and high dose DT suspension (at the daily dose of 900 mg/kg) were administered to rats in the model group, the WM group, the low dose DT group, the high dose DT group respectively by gastragavage for 8 successive weeks. The general condition of all rats was observed. Rats were sacrificed after gastric administration and their serum collected. Serum levels of lipids (TC, TG, HDL-C, LDL-C) and inflammatory factors [IL-6, TNF-α, monocyte chemoattractant protein 1 (MCP-1), oxidized low-density lipoprotein (ox-LDL), lipoprotein-associated phospholipase A2 (LP-PLA2), secretory phospholipase A2 (sPLA2)] were detected. Pathological changes of thoracic aorta were observed by HE staining. Protein and gene expressions of LP-PLA2 and sPLA2 in thoracic aorta were measured by Western blot and real-time fluorescent quantitative PCR respectively.

RESULTSCompared with the normal control group, rats in the model group were in low spirits and responded poorly. Typical atherosclerotic plaque could be seen in thoracic aorta of rats in the model group. Serum levels of TC, TG, LDL-C, IL-6, TNF-α, MCP-1, ox-LDL, LP-PLA2, and sPLA2 significantly increased (P < 0.05); protein and gene expressions of LP-PLA2 and sPLA2 in rat thoracic aorta increased (P < 0.05) in the model group. After 8 weeks of intervention, rats in 3 medication groups appeared active, and HE staining showed subsidence of plaque in rat thoracic aorta. Compared with the model group, serum levels of TC, TG, LDL-C, IL-6, TNF-α, MCP-1, ox-LDL, and LP-PLA2 decreased in 3 medication groups (P < 0.01, P < 0.05); serum sPLA2 level decreased, protein and mRNA expressions of LP-PLA2 and sPLA2 in rat thoracic aorta decreased in the WM group (P < 0.01, P < 0.05); protein and mRNA expressions of LP-PLA2 in rat thoracic aorta significantly decreased in the low dose DT group (P < 0.01, P < 0.05), and those of LP-PLA2 and sPLA2 decreased in the high dose DT group (P < 0.01, P < 0.05).

CONCLUSIONDT could fight against inflammatory reaction and AS possibly through inhibiting LP-PLA2 expression and reducing ox-LDL production.

OBJECTIVE: Aimed to analyse the clinical features of the patients with sphenoid sinus mucocele, achieve earlier diagnosis and more timely intervention and decrease the occurrence of misdiagnoses. METHOD: A retrospective study was first conducted in patients with sphenoid sinus mucoele treated in Xiangya hospital from Jan 2000 to Jan 2015. Then literature reports on this disease were collected and analyzed from China National Knowledge Infrastructure (CNKI) and Wan Fang database. RESULT: We collected 82 patients with sphenoid sinus mucocele treated in Xiangya hospital. There were 52 patients presented with headache, 31 patients presented with visual impairment, 10 patients presented with cranial nerve palsy, 2 patients presented with exophthalmos, 15 patients presented with nasal symptoms, and 5 patients with no obvious symptoms. There was no significant difference for symptoms distribution between male and female patients (P > 0.05). Among 45 patients with headache as first symptom and 10 patients with ethmoid sinus mucocele, there were 18 patients and 8 patients subsequently suffering from visual impairment, respectively. We also collected 161 patients in literature except for enrolling, the 82 patients treated in Xiangya hospital, and found that headache was the most common symptom, followed by visual impairment, in the two independent cohorts. CONCLUSION To the best of our knowledge, this is the study of maximum sample for sphenoid sinus mucocele in China. Headache and visual impairment are the most common symptoms for sphenoid sinus mucocele. Surgical treatment should be early performed when the desease accompanied with headache or ethmoid sinus mucocele, to avoid other complications such as visual impairment and even blindness.

Objective To investigate the impact of chronic disease self-management on motor function, activities of daily living, quality of life, and depression of patients in poststroke rehabilitation in community. Methods 120 stroke patients living in Gangdu community, Wuhan city were selected and randomly divided into self-management group (n=60) and control group (n=60). The control group experienced home rehabilitation and functional training by themselves, meanwhile they were asked to have regular outpatient referral and do the followup clinic when feeling indisposed. Self-management mode was used in the self-management group instructed by the professor and under the rehabilitation assessment by community doctors, therapist and family members. Also group separated instruction, individualized rehabilitation plan, home visit processes and patients' group activity had been organized. They were evaluated with Fugl-Meyer Assessment (FMA), modified Barthel Index (MBI), Hamilton Depression Rating Scale (HAMD) and the World Health Organization Quality of Life (WHOQOL-100) before and 6 months after intervention. Results There were no difference in FMA upper and lower limbs scores as well as the MBI score, HAMD score and WHOQOL-100 score before intervention (P>0.05). The FMA upper and lower limbs score, MBI score and WHOQOL- 100 score significantly improved in the self-management group and were better than in the control group 6 months after intervention (P<0.05). The control group also improved in the above items, however, the differences were not statistically significant (P>0.05). HAMD score significantly reduced in the self-management group and less than in the control group 6 months after intervention (P<0.05). The control group also reduced in the above scores, however, the differences were not statistically significant (P>0.05). Conclusion Chronic disease self-management for stroke patients in community can significantly improve their motor function, activities of daily living and quality of life, and reduce depression caused by stroke.

To observe the morphological features of endothelial cells and cardiac explants cultured in two- or three-dimensional culture systems, several three-dimensional collagen type I culture systems, such as the in gel, on gel, sandwich model, and the microscope slide model, were used to examine the growth patterns of the cells and explants from heart by using immunofluorescence staining and microscopic observation in the presence or absence of vascular endothelial growth factor (VEGF). In two-dimensional cultures the primary cardiac endothelial cells arrayed into a cobblestone-like structure. When cultured in three-dimensional matrix, the cells were elongated and migrated into the gel, with a phenotype similar to that in the process of angiogenesis and vasculogenesis in vivo. VEGF promoted the process of the endothelial cells transforming into tube-like structure. Cardiac explants grew well in the collagen gel. Adjacent explants were connected to each other by the migrating cells with the occurrence of autorhythmic beating of the explants. Thin-layer collagen gel, microscope slide chamber and aorta-strip model were also tested and proved to be good tools for vasculogenesis or angiogenesis studies. Three-dimensional culture systems enable the endothelial cells to proliferate, migrate, and anchor to three-dimensional vascular structures, showing advantages for observing the feature of angiogenesis. Different three-dimensional culture models may be used for variable research purposes.
