To observe the clinical efficacy of Artisan iris-clip intraocular lens ( lOL) implantation on cataract with a wide range of lens dislocation.
●METHODS: Twenty-four hospital patients (28 eyes) of cataract with lens subluxation by trauma (20 patients, 20 eyes) and Marfan's syndrome (4 patients, 8 eyes) during May 2007 to December 2011 were selected. All of them underwent phacoemulsification or an anterior vitrectomy and Artisan iris - clip lOL implantation at stage Ⅰ. Postoperative visual acuity, corneal endothelial cell count, intraocular lens position and postoperative complications were observed. Follow-up time was 6mo.
●RESULTS: Compared with the preoperative, postoperative best corrected visual acuity improved to varying degrees, visual acuity of 0. 1-0. 5 was in 20 eyes, 0. 5-1. 0 in 8 eyes. After followed up 1-6mo, no artificial lens shift, iris inflammation, iris atrophy and corneal decompensation and other complications were observed.
●CONCLUSlON: Cataract surgery with a wide range of lens dislocation is difficult, but as long as surgeons who have a wealth of clinical experience and superb skills, still can carry out phacoemulsification surgery or anterior vitrectomy and Artisan iris - clip lOL implantation and obtain a better outcome.

Objective: To identify the active ingredients, potential targets, and mechanism of Rhizoma coptidis by bioinformatics method, and to explore the hypoglycemic effect of Rhizoma coptidis by in vitro experiments. Methods: The chemical components of Rhizoma coptidis were collected through database search, and oral bioavailability and drug-likeness were used for preliminary screening. The targets of Rhizoma coptidis and diabetes-related targets were collected by database retrieval and reverse docking techniques, and the biological process of cross-set proteins was analyzed. The inhibitory effects of Rhizoma coptidis on α-glucosidase, α-amylase activity, and advanced glycation end products (AGEs) were determined via in vitro experiments. In addition, the effects of Rhizoma coptidis on pre-adipocyte differentiation, absorption of glucose by adipocytes, and the level of intracellular triglyceride were investigated using the adipocyte differentiation model. Results: There were 11 potentially active ingredients in Rhizoma coptidis. IL-6, caspase-3, epidermal growth factor receptor (EGFR), MYC, and estrogen receptor 1 were considered as the key genes. The bioinformatics analysis showed that Rhizoma coptidis played an anti-diabetic role mainly via biological processes and signaling pathways including hormone receptor activity, glutathione binding, steroid binding, etc. In vitro experiments showed that the extract of Rhizoma coptidis inhibited the activities of α-glucosidase and α-amylase, and the generation of AGEs; meanwhile, the extract promoted the absorption of glucose by adipocytes. In addition, the extract of Rhizoma coptidis decreased triglyceride level. Conclusions: Our network pharmacology and in vitro experiments demonstrate the anti-diabetic effects and possible underlying mechanisms of Rhizoma coptidis extract.

OBJECTIVETo observe the expression of urotensin II (UII) on the lung of patients with pulmonary hypertension (PH) with congenital heart disease and investigate the meaning of this phenomenon.

METHODThirty eight patients with CHD were divided into three groups according to pulmonary arterial systolic pressure (PASP) measured in cardiac catheterization and surgery: normal pulmonary pressure group (N group, PASP < 30 mm Hg, n = 10), mild PH group (M group, PASP ≥ 30 mm Hg, n = 15), severe or moderate PH group (S group, PASP ≥ 50 mm Hg, n = 13). The expression of UII protein and UII mRNA in pulmonary arterioles were measured separately by immunohistochemical (IHC) analysis and in situ hybridization (ISH) analysis.

RESULT(1) The results of UIIIHC staining: The UII protein expression of group M was higher than that of group N (20.22 ± 3.58 vs. 14.34 ± 2.18, P < 0.01), but less than group S (20.22 ± 3.58 vs. 28.92 ± 3.22, P < 0.05). (2) The results of UIIISH mRNA staining were similar to IHC staining, the A value of group M was higher than group N (12.51 ± 2.02 vs. 8.85 ± 1.41, P < 0.05), less than that of group S(12.51 ± 2.02 vs. 25.35 ± 4.33, P < 0.01). (3) Correlation study: there was a positive correlation between the A values of UIIIHC and pulmonary hypertension (r = 0.64, P < 0.01, n = 38), a positive correlation between the A values of UIIISH and pulmonary hypertension (r = 0.58, P < 0.01, n = 38).

CONCLUSIONThere was the expression of Urotensin II protein and mRNA in the lung of pulmonary hypertension patients with congenital heart disease, and these expression may involve the formation of pulmonary hypertension of congenital heart disease.

The objective of this study was to analyze the relationship between some chemokines and the pathogenesis of GVHD and to find some biomarkers with diagnostic significance through observing and comparing the changes of some chemokine levels in samples from patients with or without aGVHD after allogeneic hematopoietic stem cell transplantation (allo-HSCT). 26 plasma samples were obtained from 26 patients undergoing allo-HSCT at various time points after transplantation, of which 13 samples from patients with aGVHD were served as investigating group and 13 samples from patients without GVHD after Allo-HSCT were used as control group. The patient characteristics between the two groups were compared, the levels of 40 chemokines in these samples were detected by ELISA, the changes of chemokine levels in samples of 2 groups were analyzed by means of significance analysis microarray (SAM), clustering method and c-test. The results showed that there were significant differences in levels of 6 chemokines including HCC-1, MIF, IP-10, ITAC, TARC and NAP-2 between 2 groups, in which the level of MIF in plasma samples after HSCT was the highest, the difference of TARC level between 2 groups was over 10-fold. It is concluded that the level changes of chemokines mentioned above can be used as a indicator of GVHD presence, but their pathogenetic role in occurrence of aGVHD remains to be determined.

Objective: To investigate whether insulin stimulates the translocation of glucose transporter-4 (GLUT4) and glucose uptak e in ischemic myocardium. Methods: Plasma concentration of gluc ose, lactate, free fatty acid and insulin were determined by autoanalyser, and G LUT4 was studied by Western blotting analysis. Results: Insulin increased GLUT4 significantly in sarcolemma of ischemic myocardium ［(25±4)% vs (40±6)%］, and GLUT4 content in intracellular membrane decreased proporti onally. The glucose uptake increased significantly in insulin-ischemic myocardi um. The uptake of insulin-ischemic myocardium was almost 2 times that of ischem ic myocardium. Conclusion: Insulin stimulation results in GLUT4 translocation and increases glucose uptake in ischemic myocardium. When myocardi al ischemia occurs, insulin is helpful in increasing myocardial glucose uptake a nd utilization.

BACKGROUNDWide application of umbilical cord blood transplantation (UCBT) in adult patients is limited by low cell-dose available in one umbilical cord blood (UCB) unit. The aim of this study was to investigate the safety and long-term outcomes of UCBT from unrelated donors in adult and adolescent patients with leukemia.

METHODSThirteen patients with leukemia received double-unit UCBT with human leukocyte antigen (HLA) mismatched at 0 - 2 loci. We analyzed the engraftment, graft-versus-host disease (GVHD) and survival.

RESULTSTwelve evaluable patients (92.3%) had neutrophil and platelet engraftment at a median of 21 days (range, 16-38 days) and 34 days (range, 25 - 51 days), respectively. At day 30, engraftment was derived from one donor in 8 patients (66.7%, 95%CI 40.0% - 93.4%), and from both donors in 4 patients (33.3%, 95%CI 6.7% - 60.0%) with 1 unit predominated. Unit with larger nucleated cell (NC) dose would predominate in engraftment (P = 0.039), whereas CD34(+) cell dose or HLA-match failed to demonstrate any relationship with unit predominance. Only one patient developed grade II acute graft-versus-host disease (aGVHD). Chronic GVHD (cGVHD) was observed in 2 of 11 patients who survived more than 100 days, and both were limited. The median follow-up after transplantation for the 13 patients was 45 months (range 1.5 - 121.0 months) and 72 months (range 41.0 - 121.0 months) for the 8 alive and with full donor chimerism. The 5-year cumulative disease free survival (DFS) was (61.5 ± 13.5)%. Of the 13 patients, 5 patients died in 1 year and 1-year transplantation related mortality (TRM) was 23.1% (95%CI 0.2% - 46.0%).

CONCLUSIONDouble-unit UCBT from unrelated donors with HLA-mismatched at 0-2 loci may overcome the cell-dose barrier and be feasible for adults and adolescents with leukemia.

OBJECTIVETo explore the comprehensive program of integrated Chinese and western medicine in the treatment of cognitive impairment in earthquake brain injury.

METHODSThe multi-central randomized controlled trial was adopted. The qualified subjects were randomized into an acupuncture + rehabilitation group (38 cases) and a rehabilitation group (35 cases). In the acupuncture + rehabilitation group, acupuncture, hyperbaric oxygen (HBO) and cognitive rehabilitation training were combined as the comprehensive program of integrated Chinese and western medicine in the treatment. In the rehabilitation group, HBO and cognitive rehabilitation training were adopted. The efficacy and safety were assessed.

RESULTS(1) After treatment of 2 months, the intelligent state, cognitive function and activity of daily life of patients were improved in the both groups (all P < 0.01). (2) After treatment of 2 months, the score of MMSE and the score of activity of daily life were (24.11 +/- 4.08) and (75.45 +/- 13.95) in the acupuncture + rehabilitation group, which were more significant as compared with (17.05 +/- 43.84), (66.06 +/- 12.75) in the rehabilitation group, respectively (both P < 0.01). In 6-month follow-up visit after treatment, the cognitive function and activity of daily life were improved continuously in the acupuncture + rehabilitation group, which was more significant as compared with the rehabilitation group (P < 0.01, P < 0.05).

CONCLUSIONThe integrated Chinese and western medicine of acupuncture, HBO and cognitive rehabilitation training is safe and effective in the treatment of cognitive impairment in earthquake brain injury. The therapeutic effect is more advantageous as compared with the simple rehabilitation program of western medicine.

OBJECTIVETo investigate the association of Apa I polymorphism in vitamin D receptor (VDR) gene with bone mass in men.

METHODSThe VDR Apa I genotype was determined by PCR-restriction fragment length polymorphism (RFLP) in 388 unrelated healthy men aged 46-80 years of Han nationality in Shanghai city. Bone mineral density (BMD) and bone mineral content (BMC) at lumber spine 1-4 (L1-4) and at any sites of proximal femur including to femoral neck (Neck), trochanter (Troch) and Ward's striangle (Ward's) were measured by duel-energy X-ray absorptiometry.

RESULTSFrequencies distribution of VDR Apa I genotype were aa for 48.1%, Aa for 44.2% and AA 7.7%. The allele frequencies of Apa I polymorphism were in Hardy-Weinberg equilibrium. No significant association was found between Apa I genotype and BMD or BMC in group of all population or in subgroup of men below 60 years. In men above 60 years, the significant association was found between VDR Apa I genotype and BMD or BMC at L1-4, Neck and Ward's (P < 0.05, P < 0.01) and compared with Aa and aa genotype, AA genotype had significantly higher mean BMD and BMC at L1-4, Neck and Ward's (P < 0.05, P < 0.01). But Apa I genotype is not associated with BMD and BMC at Troch.

CONCLUSIONSApa I polymorphism is associated with bone mass in men above 60 years, and AA genotype has higher bone mass. Apa I polymorphism in VDR gene possibly influence loss of trabecular and cortical bone mass in old men.

OBJECTIVETo investigate the relationship of Msp AI polymorphism in the promoter region of cytochrome P450c 17alpha (CYP17) gene with bone mass and bone size in Shanghai men of Han nationality.

METHODSThe CYP17 Msp AI genotype was determined by polymerase chain reaction-restriction fragment length polymorphism in 397 unrelated men (324 healthy men, 73 osteoporosis patients) aged 46-80 years of Han nationality in Shanghai. Bone mineral density (BMD), bone mineral content (BMC), and bone cross-section area (CSA) at lumber spine 1-4 and at any sites of proximal femur, including femoral neck, trochanter and Ward's triangle were measured by duel-energy X-ray absorptiometry.

RESULTSFrequency distributions of CYP17 genotype were TC (51.1%), CC (33.8%), and TT (15.1%). The allele frequencies T and C were 40.7% and 59.3%, respectively. Allele frequencies did not deviate from Hardy-Weinberg equilibrium. The frequencies of CYP17 Msp AI genotype did not show difference between osteoporosis cases and healthy controls. In group of all population, or in subgroups of osteoporosis patients and healthy men, CYP17 Msp AI genotype was not significantly associated with BMD, BMC, and CSA at lumber spine 1-4 and at any sites of proximal femur after having been adjusted for age, weight, and height with analysis of covariance.

CONCLUSIONMsp AI polymorphism of CYP17 gene is not a genetic factor that influence the variation of bone mass and bone size in Shanghai men of Han nationality.
