Diabetic cataract is an metabolic-type cataract. Its pathogenesis mechanism is not completely clear. Researches demonstrated that glycosylation plays an increasingly important role in the formation of diabetic cataract,and increased blood glucose level promote the pathogenesis and progression of diabetic disease by accelerate the glycosylation response. Therefore, more researches on advanced glycation end products(AGEs) and its inhibitors is being concerned. The advance in the study of AGEs concept, its effect on diabetic cataract formation, the influence of AGEs inhibitor on diabetic cataract are summarized in this article.

Objective To explore the impact of overweight and obesity on flow mediated dilation (FMD) in adult people.Methods Intact clinical data of 183 healthy people, aged 30~65 in our hosipital were analyzed.According to BMI, all people were divided into obesity group (48 cases), overweight group(75 cases) and normal group (60 cases).FMD was detected by E tracing of ultrasonic.Weight, WC, BFP, baPWV, BP,FPG,CHO,HDL-C,LDL-C,TG and UC were observed at the same time.FMD of three groups were compared and the risk factors of FMD were analyzed.Results The level of FMD in the obesity group and overweight group was significantly higher than that in the normal group[(5.63±2.76)%,(6.45±2.54)% vs.(8.31±3.04)%](F=13.77,P<0.001);there was no statistically significant difference between the obesity group and overweight group (t=1.68,P>0.05).Age(β=0.078,95%CI: 1.004,1.164),BMI(β=0.465,95%CI 1.148,2.208),LDL-C(β=2.294,95%CI: 9.918,1.612) and UC(β=0.007,95%CI 0.986,1.000) were independent risk factors of decreased FMD(P<0.05).Conclusion Age, BMI, LDL-C and UC are independent risk factors of decreased FMD.

ObjectiveTo investigate the clinical efficacy of the fixation of elderly fracture of proximal humerus with locking compression plate(LCP) by mini-incision approach from lateral shoulder.Methods31 elderly patients suffered from elderly fracture of proximal humerus were treated with locking compression plate(LCP) by mini-incision approach from lateral shoulder, male 13 cases, female 18 cases; aged from 56 to 72, average 62-8 years old; fractures according to Neer classification: type Ⅱ(8 cases), type Ⅲ (19 cases), type Ⅳ (4 cases). Cause of injuries: traffic accident (9 cases), falling (20 cases), other injuries(2 cases).ResultsThe patients were followed up 6 to 36 months, an average of about 24 months. Fracture healing time was 2-2 ～ 6-4 months, on average 3-7 months; No wound infection occurred. Post-operative functional score (Neer score) revealed: excellent(18 cases), good (11 cases), fair (2 cases), the ratio of excellent(18 cases), good (11 cases) was 93-5%. ConclusionFixation of elderly fracture of proximal humerus with locking compression plate(LCP) by minimally invasive approach from lateral shoulder is a safe, reliable and minimally invasive procedure with good reduction and stable fixation. Early post-operative functional exercise may be permitted for preventing shoulder joint adhesion.

The clinical features and lung CT findings of 174 heart failure patients,including 85 cases with normal left ventricular ejection fraction (LVEF) and 89 cases with reduced LVEF were reviewed.Patients with normal LVEF had a higher proportion of hypertension,diabetes and obesity than patients with normal LVEF; and cough and dyspnea were more common.The lung CT findings in patients with normal LVEF were frequently presented as interstitial lung edema,increased pulmonary texture,subpleural line,Kerley lines and diffuse ground-glass opacity.Patients with reduced LVEF had a higher proportion of coronary heart disease and clinical manifestations of acute left heart failure,and central alveolar edema presented in lung CT images.Results suggest that heart failure patients with normal LVEF usually have longer clinical history and occult symptoms,and have a different lung CT imaging features from those in heart failure patients with reduced LVEF.

Background With the changes of diet and living style,the diabetes has become the major diseases affecting human health.Diabetic cataract is a common complication of diabetes. Objective The present study was to investigate the difference of lens proteomics between diabetic cataract and age related cataract using two dimensional electrophoresis (2-DE) and mass spectrometry in order to postpone happening of diabetic cataract and offer the effective approach to the prevention and therapy of diabetic cataract. Methods The lenses were obtained from 8 diabetic patients and 12 age-related cataract patients during the surgery to extract the protein by lysis and centrifugation.The lens proteins were separated using immobilized pH gradients 2-DE.Image analysis was carried out using PDQuest Advanced-8.0.1 software package.Significant difference of the crystallines was identified by matrixassisted laser adsorption/ionization time of-flight-mass spectrometry (MALDI-TOF-MS) and peptide mass fingerprint combined with protein database. Results The maps of 2-DE showed that lens proteins of diabetic cataract and age related cataract were in the section of pH 5-9 with the relative molecular weight 14000-97000;while relative molecular weight of more abundant crystalline was localized at 20000-31000.About 3 differential protein spots were detected by image analysis software.Two crystallines,αB and βB1 crystallin,were identified using MALDI-TOF-MS.Conclusions Proteomic analysis of lens can be accomplished and the proteins can be well separated,moreover,differential proteins can be analyzed using 2-DE and mass spectrometry between diabetic cataract and age related cataract.These results indicate that αB and βB1 crystallin proteins accelerate the development of diabetic cataract.This technique offers a new avenue for clarity of lens proteins of diabetic cataract other than age related cataract.

BACKGROUND:In recent years,artificial cervical disc replacement surgery as a new method for the treatment of cervical disease has gradualy been accepted and understood,but relevant complications have gradualy attracted attention.OBJECTIVE:To investigate the clinical outcomes of artificial cervical disc replacement in the treatment of cervical disease and the range of motion of the replacement segment.METHODS: A total of 25 patients with artificial cervical disc replacement in the treatment of cervical spondylosis,who were treated in the Department of Orthopedics,Air Force General Hospital of Chinese PLA from August 2006 to April 2012,were enroled in this study,including 15 males and 10 females,aged 31-76 years,averagely 51.04 years.There were 6 cases of double segments and 19 cases of single segment.They were folowed up for 24 to 93 months.Clinical results were assessed using the Japanese Orthopaedic Association score,cervical dysfunction index and pain visual analog scale scores.Imaging was used to observe range of motion,cervical curvature,heterotopic ossification,and degeneration of adjacent segments.RESULTS AND CONCLUSION:Neurological function in al patients was improved to different degrees.One case suffered from mild heterotopic ossification,but no clinical symptoms were found.No significant difference in range of motion of surgical segment,and range of motion of upper and lower adjacent segments was detected between pre-replacement and final folow-up results (P＞0.05).No significant difference in range of motion of C2-C7 was found between pre-replacement and final folow-up results (P＞0.05).Japanese Orthopaedic Association score,cervical dysfunction index and pain visual analog scale scores were significantly improved during final folow-up compared with pre-replacement (P＜0.05).These results indicated that artificial cervical disc replacement in the treatment of cervical disease can achieve better clinical efficacy,can keep the range of motion of replacement segment and avoid the accelerated degeneration of adjacent segments.

16 and the distribution of severe trauma more than 2 anatomic parts.They were randomly divided into two groups:intensive insulin treatment group(n=31)and control group(n=31).Intensive insulin treatment group received insulin with insulin pump in order to maintain blood glucose levels at 4.0-6.1 mol/L,while the control group received routine insulin treatment in order to mmaintain blood glucose levels at 10.0- 11.0 mol/L.Plasma levels of TNF-?,IL-1,IL-6, CRP,APACHEⅡscores and cure rate were analyzed before and after the treatment.Data was expressed as mean?standard deviation.Two- tailed T test and ANOVA were used for comparison in SPSS 10.0,and changes were considered as statistically significant if P value was less than 0.05.Results After the intensive insulin treatment, patient's hemodynamic parameter apparently improved,APACHEⅡscores descended,and the levels of TNF-?, Ib-1,IL-6,CRP all declined,in comparison with control group,there were significant differences. Intensive insulin treatment might improve patient's general condition and decrease complications and mortality of severe multiple trauma.

31 patients with cysticercosis of cerebral ventricles verified by operation or pathological investigation were reported. All patients were between 7 and 64 years of age and 14 were females. All had a single cyst. Since 29 patients (94%) were without a history of intestinal taeniasis, it was proposed that most patients of cysticercosis of cerebral ventricles were caused by hetero-infection and the entrance of Cysticercus into brain ventricle was through choroid plexus along the cerebro-spinal fluid. This is probably the reason why it occurs mostly in the 4th ventricle. The clinical manifestation of cysticercosis of cerebral ventricles were paroxysmal headache and vomiting caused by increased intracranial pressure. Ventricu-lography and CT scanning have considerable diagnostic value. Removal of Cysticercus by surgical operation is successful (Figs. 1 - 8).

Objective:To explore the effect of weight loss on endothelial function and cerebrovascular risk factors in obese and overweight people.Methods:A total of 127 obese or overweight subjects received 6-month body weight management. Subjects who lost 3 kg or more than 5% of their body weight prior to the 6-month intervention were defined as achievement group. Endothelial function (FMD) and other cerebrovascular risk factors were measured before and after intensified lifestyle management.Results:The achievement group comprised 57 (44.9%) cases and the non-achievement group 70 (55.1%) cases. After 6-month intervention, FMD (6.98±2.88% vs 7.90±2.96%, P<0.05) and HDL-C increased in the achievement group. Significant decreases were observed in the achievement group in BMI, SBP, DBP, FPG, TC, LDL-C, TG and uric acid. However, only DBP and FPG decreased in the non-achievement group. Conclusion:Weight loss can reverse endothelial dysfunction and metabolic dysfunction. Decrease of body fat ratio contributes to the improvement of endothelial function.
