Objective To investigate the expression and significance of inducible co-stimulator (ICOS) in experimental autoimmune uveoretinitis (EAU). Methods EAU was induced in 24 Lewis rats (immune group) by immunization with retinal S-antigen (50 ?g) and complete Freund′s adjuvant, and another 4 rats were in the control group. Anterior segment of the rats′ eyes were observed by split microscope every day. Immunohistochemical staining was performed using polyclonal antibodies to ICOS on the sections of the spleen which were obtained from the rats in immune group at the 7th, 12th, 15th and 21st days after immunisation respectively. Western blotting was performed to investigate the dynamic expression of ICOS protein in the spleen. The same procedures were made at the corresponding time points in the rats in control group. Results A few ICOS positive cells were observed in the normal spleen. The number of ICOS positive cells in immune group increased obviously at the 7th and 12th days after immunization, reached the peak at the 15th day, and decreased at the 21st day which was still higher than that in the control group. The result of Western blotting showed that the dynamic changes of ICOS protein was identical with the changes of positive-cell number detected by immunohistochemistry. Conclusions The enhanced expression of ICOS happens before EAU occurs, which increases when the inflammation occurs and deteriorates, and decreases at the alleviative stage of EAU. It suggests that ICOS participates in the formation, development and disappearance of EAU and plays an important role in the incidence of EAU.

OBJECTIVE To investigate the distribution and resistance of commonly encountered pathogens in a General Hospital,and provide reference for antimicrobial agents usage.METHODS All pathogenic bacteria were isolated from the clinical specimens during the last four years and samples were identified.K-B method was performed to test the antibiotic resistance.RESULTS Among 1643 isolates,The Gram-negative bacteria Pseudomonas aeruginosaand Escherichia coli,and the Gram-positive bacteria Staphyococcus epidermidisand S.aureus were the main pathogens.The P.aeruginosa was highly resistant to broad-spectrum penicillins,third-generation cephalosprins,aminoglycosides and quinolones.But impenem showed activity against Gram-negative bacilli,with resistant rates less than

Objective:To elucidate the gene mutation presents in hair follicle cells,just as blood cells,in the aminoglycoside antibiotics induced deaf patients (AAID). Method:Mitochondrial DNA of blood cells and/or hair follicle cells from 8 members of 3 aminoglycoside antibiotics induced deafness families were analysed using PCRSSCP and Alw 26 Ⅰ digestian. Result:Our result showed that a gene mutation at nuleotide 1555 in 12 S rRNA of mitochondrial DNA appeared in blood cells and/or hair follicle cells of 7 subjects among those 8 members. Only a father with normal hearing did＇t exhibit such a mutation. Conclusion:This indicated that hairs could be used as a sample instead of blood to perform gene examination for AAID.

Objective To explore the correlation between cognitive ability and motor ability in stroke patients.Methods 30 stroke patients were assessed with the 3 m Timed Up and Go Test (TUG). The anticipated time by patients and the actual time were recorded, and their difference was caculated, named as the cognitive error. They were also assessed with Trail Making Test-Part A (TMT-A). The actual time of TUG, cognitive error and the time of TMT-A was compared among different groups of Brunnstrom stage of lower limb, and their correlation was analyzed. Results There was a significant difference between the actual time of TUG between Brunnstrom stage Ⅲ and Ⅴ (F=4.600, P<0.05). There was positive correlation between actual time of TUG and cognitive error（r=0.844, P<0.01）, time of TMT-A and cognitive error（r=0.508, P<0.01）, time of TMT-A and actual time of TUG （r=0.414, P<0.05）. Conclusion Motor ability of stroke patients can be influenced by deficient attention and motor cognition.

From June 2008 to December 2012,video-assisted thoracoscopic surgery (VATS group) was performed for 24 cases of thymoma.Their operative procedures,postoperative complications,remission of myasthenia gravis (MG),perioperative mortality and oncological outcomes were compared with 19 cases of trans-sternal open thymectomy (OT group).Compared with OT group,VATS group had significantly shorter operation duration,less blood loss,shorter postoperative hospital stay,shorter chest tube duration and less chest drainage amount (P ＜ 0.05).The total rate of postoperative complications of VATS group was 4％ (1/24) and it was less than OT group (4/19) without significant difference (P ＞0.05).The effective remission rate of thymomatous MG was 7/9 in VATS group and it was similar to that in OT group (6/8,P ＞ 0.05).VATS group had a recurrent or metastatic rate of 0％ (0/23) and it was better than OT group with 1/17.And there was no significant inter-group difference (P ＞ 0.05).The total survival rate of VATS group was 100％ and it was similar to that of OT group (16/17,P ＞ 0.05).Thoracoscopic thymectomy is safe,feasible,efficacious and mini-invasive for thymoma.With fewer complications and a quicker recovery,it has similar short-term outcomes to conventional open thymectomy.

BACKGROUND: Orotracheal intubation with conventional Macintosh laryngoscope often makes strong alterations in hemodynamic responses. Compare with the Macintosh laryngoscope, the Airtraq~((R)) laryngoscope has weak effect on throat irritation. However, the contrast effect on hemodynamics remains still unknown. OBJECTIVE: To compare the hemodynamical responses to orotracheal intubation between Airtraq~((R)) laryngoscope and Macintosh laryngoscope. DESIGN, TIME AND SETTING: A randomized comparative observation was performed at Department of Anesthesiology, Dalian Second People's Hospital between October 2008 and April 2009. PARTICIPANTS: A total of 40 patents scheduled for surgery under general anesthesia requiring orotracheal intubation were randomly divided into Airtraq~((R)) laryngoscope group and Macintosh laryngoscope group, with 20 cases in each group. METHODS: After standard intravenous anesthetic induction, orotracheal intubation was performed with Airtraq~((R)) laryngoscope or Macintosh laryngoscope. Common Airtraq~((R)) laryngoscope was used in the Airtraq~((R)) laryngoscope group, and an endotracheal tube with internal diameter of 8.0 was inserted. No. 3 lens were used in the Macintosh laryngoscope group, and an endotracheal tube with internal diameter of 8.0 was inserted. MAIN OUTCOME MEASURES: Glottic exposure time, tracheal intubation time, noninvasive heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) before (T0) and after (T1) anesthetic induction as well as at 0 minute (T2), 1 minute (T3), 2 minutes (T4), and 3 minutes (T5) after intubation, as well as rate-pressure product (RPP). RESULTS: The glottic exposure time in Airtraq~((R)) laryngoscope group was significantly longer than that in Macintosh laryngoscope group (P < 0.01), while the tracheal intubation time in Airtraq~((R)) laryngoscope group was significantly shorter than that in Macintosh laryngoscope group (P < 0.01). Compared with pre-induction (T0), the SBP, DBP, and RPP of the two groups decreased significantly after anesthetic induction (T1) (P < 0.05), but the HR did not change remarkably (P > 0.05). Compared with T1, all hemodynamical values at T2, T3, T4 and T5 in Airtraq~((R)) laryngoscope group did not increased sign ificantly (P > 0.05). In Macintosh laryngoscope group, HR and RPP at T4, SBP, DBP, HR and RPP at T2 and T3 increased significantly compared with T1 (P < 0.05). In Macintosh laryngoscope group, HR and RPP at T2, T3 and T4 were significant higher than that in Airtraq~((R)) laryngoscope group (P< 0.05). CONCLUSION: In comparison to the Macintosh laryngoscope, tracheal intubation with the Airtraq~((R)) laryngoscope resulted in less alterations in hemodynamical responses.

Objective To investigate the effect of blood pressure management on perihematomai edema in patients with acute hypertensive intracerebral hemorrhage. Methods The retrospective research method was used to conduct logistic regression analysis for the factors of age, number of days, antihypertensive drugs, dehydrating agents, and blood pressure in inpatients with hypertensive intracerebral hemorrhage from June 2005 to December 2007. Results Multivariate analysis found that both amlodipine (OR = 0. 208, 95% CI 0. 063-0. 684) and angiotensin-converting enzyme inhibitor (ACEI) (OR = 0. 280, 95% CI 0. 085-0. 920) were the protective factors for perihematomal edema; both the course of 10 to 20 days (OR =7.413, 95% CI 1. 362-40. 360) and poorly controlled diastolic blood pressure (OR = 6. 449, 95% CI 1. 011-41. 145) were the risk factors for perihematomal edema. Conclusions Amlodipine and ACEI may lower the risk of perihematomal edema in intracerebral hemorrhage, while the poorly controlled diastolic blood pressure and the course of 10 to 20 days are the risk factors for perihematomal edema.

Objective To evaluate the outcome of liver transplantation (LT) or combined liver-kidney transplantation (CLKT) for acute-on-chronic liver failure (ACLF) patients with renal dysfunction.Method From January 2001 to December 2009,133 patients underwent LT for ACLF at our center.Among them,30 had both ACLF and renal dysfunction.Of the 30 patients,12 underwent CLKT for end-stage renal disease (ESRD),and the other 18 with hepatorenal syndrome type 1 (HRS1) underwent LT alone.Their clinical data were reviewed and their survival outcomes were compared.Result The median model for end-stage liver disease scores (MELD) of the patients with ACLF were 28.133 patients received deceased donor liver grafts and 12 patients also received the same deceased donor kidney grafts,The hospital mortality rate was 21.8％ for all patients with ACLF.The 5-year survival rates were 72.8％ for patients without renal dysfunction and 70％ for patients with renal dysfunction.The curative effectiveness of the patients with ESRD who underwent CLKT was better than that of the patients without renal dysfunction or the patients with HRS1 who underwent LT alone.Conclusion LT alone improved renal function in most patients with HRS1.Simultaneous liver-kidney transplantation is an excellent strategy in patients with both ACLF and ESRD.It provides protection to kidney allograft in liver-based metabolic diseases affecting the kidney.

AlM: To explore the clinical therapeutic effect of the integrated traditional Chinese and Western medicine treatment of idiopathic panuveitis.
METHODS: Totally 47 patients ( 69 eyes ) with the idiopathic panuveitis were included in this study, which were randomly divided into control group and treatment group. Twenty-four cases (33 eyes) with the method of Western medicine-glucocorticoid and mydriatic were in control group, while 23 cases (36 eyes) with integrated traditional Chinese and Western medicine were in treatment group. Those patients were followed up 12-36mo, the vision before and after treatment, the therapeutic effects, the complications and the side effects of glucocorticoid were recorded.
RESULTS: Both of two groups' vision after treatment were improved, but the vision of treatment group was better than the control group. The effective rate and the cure rate of the treatment group were increased significantly. Of all of the complications, the incidence rate of complicated cataract and secondary glaucoma of the treatment group were reduced significantly. Of all of the side effects of glucocorticoid, the central excitation, hypertension and central obesity of the treatment group were reduced significantly (P<0. 05).
CONCLUSlON: Dialectical therapy of integrated traditional Chinese and Western medicine has better therapeutic effect than simple Western medicine treatment of idiopathic panuveitis, and could better reduce the side effect of glucocorticoid long-term use. lt is worthy applying in clinical practice.

Objective:To investigate the expression of miR-151a-3p in peripheral blood mononuclear cells (PBMCs) of children with lupus nephritis (LN) and its correlation with activity and vascular damage.Methods:A total of 87 children with LN admitted in Hainan Women and Children′s Medical Center from January 2016 to March 2019 were enrolled, including 16 cases of type Ⅱ, 14 cases of type Ⅲ, 34 cases of type Ⅳ, 17 cases of type Ⅴ and 6 cases of type Ⅵ.Besides, additional 40 children with normal physical examination were selected as the healthy control group.The 87 children with LN were divided into the LN stable group (31 cases) and LN active group (56 cases) by using systemic lupus erythematosus disease activity index (SLEDAI) scores.According to different proportions of the medium membrane, the patients were classified into the mild group (25 cases), moderate group (34 cases) and severe group (28 cases). Real time quantitative PCR (qPCR) was used to detect the expression level of miR-151a-3p in PBMCs of each group.The correlation of the expression level of miR-151a-3p in PBMCs of LN children with the SLEDAI score and renal interstitial damage score was studied by Pearson correlation analysis. Results:The expression levels of miR-151a-3p in the LN group, LN active group and LN stable group (0.47 ± 0.06, 0.30 ± 0.04, and 0.75±0.12, respectively) were significantly lower than that in the healthy control group (1.62±0.35) (all P<0.01), and the expression level of miR-151a-3p in the LN active group (0.30±0.04) was significantly lower than that in the LN stable group (0.75±0.12) ( P< 0.01). The SLEDAI score [(14.35±4.60) points vs.(8.25±2.24) points] and renal interstitial damage score [(52.70±6.30) points vs.(34.80±4.10) points] in the LN active group were significantly higher than those in the LN stable group (all P<0.01). The expression levels of miR-151a-3p (0.18±0.02, 0.41±0.05 vs.0.83±0.16) in type Ⅴ-Ⅵ and type Ⅳ groups were significantly lower than that in the type Ⅱ-Ⅲ group (all P<0.01). The SLEDAI scores [(16.50±5.28) points, (12.36±3.74) points vs.(6.40±1.70) points] and renal interstitial damage scores [(62.70±7.40) points, (47.20±5.80) points vs.(25.80±3.50) points] in type Ⅴ-Ⅵ and type Ⅳ groups were significantly higher than those in the type Ⅱ-Ⅲ group (all P< 0.01). The expression levels of miR-151a-3p (0.20±0.02, 0.39±0.04, 0.86±0.18 vs.1.62±0.35) in severe, moderate and mild groups were significantly lower than that in the healthy control group (all P<0.01), and the expression level of miR-151a-3p decreased with the aggravation of vascular damage.The SLEDAI scores [(15.20±5.10) points, (12.85±3.90) points vs.(6.70±1.82) points] and renal interstitial damage scores [(57.30±6.80) points, (51.60±6.30) points vs.(27.20±3.60) points] in the severe and moderate groups were significantly higher than those in the mild group (all P<0.01). The expression level of miR-151a-3p in LN children was negatively correlated with the SLEDAI score and renal interstitial damage score ( r=-0.682, -0.627, all P<0.001). Conclusions:The expression level of miR-151a-3p in PBMCs of LN children is significantly decreased.The declined miR-151a-3p level is closely related to disease activity and vascular damage, and may be involved in the occurrence and development of LN.
