BACKGROUND: The change of the axial angle of the lower limb is related to the occurrence and development of osteoarthritis.OBJECTIVE: To analyze the correlation between the change of lower limb power line and pain area in the knee osteoarthritis patients.METHODS: Totally 65 knee osteoarthritis patients were selected as pain group and 30 healthy people were selected as control group. All the participants took anteroposterior and lateral knee radiographs through PACS imaging systems to collect six imaging indexes, including install index, the degree of tibiofemoral joint subluxation, tibiofemoral inside and outside joint clearance ratio, femoral angle, tibial angle and tibiofemoral angle. Knee osteoarthritis patients in pain group were divided into two common clinical pain areas which were proparea and medial area.RESULTS AND CONCLUSION: (1) The insall index, the degree of tibiofemoral joint subluxation, tibiofemoral inside andoutside joint clearance ratio between knee osteoarthritis patients in pain group and people in healthy control group hadsignificant differences. There was no statistical significance in the femoral angle, tibial angle and tibiofemoral angle. (2) In terms of the comparison between proparea and medial area in knee osteoarthritis patients in pain group, tibiofemoral joint subluxation degree was statistically different. (3) These findings suggest that there was a higher patella in knee osteoarthritis patients who were in pain, more severe in the degree of tibiofemoral joint subluxation, and more limited in tibiofemoral inside and outside joint clearance ratio. The degree of tibiofemoral joint subluxation of proparea was more severe than medial area in pain group.

The diagnostic value of glutamic acid decarboxylase antibody (GAD 65-Ab) was more valuable than islet cell antibody (ICA) in type 1 diabetes mellitus by receiver-operating characteristic (ROC) curves; likelihood ratios of different regions of GAD 65-Ab and ICA could reflect the probability of type 1 diabetes mellitus.

Objective To introduce a new major autoantigen and autoantibody in insulin-depenent diabetes mellitus.Meothds An English-lanuage literature was searched using MEDLINE (1992-1997.6). After independently reviewed by three observers, 19 of 30 originally indentified articles were selected that specifically indentified articles were selected that sepcifically addressed the stated purpose. Three observers independently asessed the biological properites and relationship with insulin-dependent diabetes meliitus of ICA512.Results ICA512 is a new member of the protein typrosine phosphatase family. Sixty-six percent of patients with insulin-dependent diagbetes mellitus have autoantibodies to ICA512. The positive prdictive value of ICA512 autoantibodies is 74.5%, in first-degree relatives of insulin-dependent diabetes mellitus. The combination of antibodies may increase the sensitivity to 100%. First-degree relatives with all three autoantiodies to insulin, glutamate acid decarboxylase, ICA512 had a risk of diabetes within 5 years estimated to be 100%.Conclusions Autoantibodies to ICA512 alone or combinedly with other autoantibodies are of great importance in the prediction and diagnosis of insulin-dependent diabetes mellitus.

The effects of glipizide on SI、SG、KG、Iarea 0～20min、FBG、FINS with minimal model in non-insulin-dependent diabetes meIlitus were observed.The results showed SI、SG、KG、Iarea 0～20min were lower and FBG was higher in NIDDM than these in normal subjects before glipizide therapy.After two weeks of glipizide therapy,FBG was decreased and SI、SG、KG、Iarea 0～20min were increased.These data suggested that glipizide not only had the effect on stimulating islet ?-cell secretion,but also improving insulin sensitivity and glucose effectiveness.

Objective To study the characteristics of ? cell function change and to explore the predictive value of glutamic acid decarboxylase (GAD)-Ab and other factors for ? cell function in the patients with latent autoimmune diabetes of adults (LADA). Methods Sixteen LADA patients (positive GAD-Ab) and 24 type 2 diabetic patients (negative GAD-Ab) were followed-up at 0, 6th, 12th, 30th, 36th, 42th and 48th months respectively. Their fasting and postprandial 2h C-peptide and glycemic control were measured. GAD-Ab was determined by radioimmunoprecipitation assay and C-peptide by RIA. Results Decreased fasting C peptide (FCP) levels (Month 30, 36, 42, 48 compared with Month 0, P

Objective To investigate whether the median(50%)effective effect-concentration(EC50)of propofol inducing loss of consciousness (LOC) varies. Methods 56 patients undergoing gastroscopy under general anaesthesia were enrolled on the study. Anaesthesia was conducted with a target-controlled infusion(TCI) of propofol. The initial target effect-site propofol concentration (Ceprop) was 5.00 μg/mL and was adjusted stepwise by 0.50μg/mL by an up-down sequential method to reach no-movement. Results Propofol EC50 to induce no-movement was higher in patients with anxiety than those without anxiety(6.46μg/mL vs. 5.75μg/mL,P<0.05). Conclusions During general anaesthesia ,patients with anxiety had a higher propofol EC50 for no-movement compared with those without anxiety. Differences in preoperative anxiety levels may reduce anaesthetic effects.

Objective To investigate the effects of light acute hypervolemic hemodilution on early postop-erative cognitive function in elderly patients. Methods A total of 60 patients treated by radical surgery were equally randomized to an AHH and a non-AHH control group.Using the Mini-Mental State Examination scale (MMSE),we evaluated the cognitive function of the patients.We made comparisons between the two groups in the plasma S100β levels at T0(before anesthesia induction),T1(immediately after hemodilution),T2(immediately after operating),T(36 hour after operating)and T(424 hour after operating).Results The S-100β lever at T2、T3 and T4were markedly higher than T0in both groups(P<0.05);At T3and T4,the S-100β lever was higher in non-AHH control group than AHH group(P<0.05).There was no significant difference in the incidence of postopera-tive cognitive dysfunction between the two groups(P>0.05)There was no significant difference in the incidence of postoperative cognitive dysfunction between the two groups(P > 0.05). Conclusions AHH can significantly reduce plasma S100β in elderly patients,but there is no effect on early postoperative cognitive function.

Objective To evaluate the etiology,epidemiological characteristics,clinical diagnosis,and outcomes of hospitalized patients with AKI in Xinjiang,analyzing the risk factors of their clinical prognosis.Methods A multicenter retrospective survey was conducted,investigating adult patients admitted to four hospitals in Xinjiang in January and July 2013.Patients with AKI were screened out based on KDIGO's inclusion and exclusion criteria.Clinical variables of patients with AKI including demographics,clinical data,laboratory tests,treatment measures and prognosis were collected.Results Among 32,157 adult hospitalized patients,there were 722 AKI patients.Excluding those with incomplete data,719 patients were enrolled in this study.The detection rate of AKI was 2.25％ (722 of 32,157) by KDIGO criteria.The main cause for AKI was pre-renal injury,led mainly by cardiac output,low blood volume,and the use of nephrotoxic drugs.The non-recognition rate of AKI was 72.4％ (407/557).Multivariate binary logistic regression analysis showed that AKI stage,peripheral vasodilation and renal parenchyma were protective factors of the omission diagnosis.In the short-term prognostic analysis,the overall mortality rate was 12.8％(92/719).Among the 323 patients with AKI who survived discharge,43.7％(141) had renal function recovery;40.2％(130) did not fully recover their renal function but ceased maintenance dialysis;16.4％ (53) were still on dialysis at discharge.Multivariate Cox regression model suggested that DIC,shock and department of obstetrics were independent risk factors for death during hospitalization of AKI.In addition,the risk of death for AKI from department of obstetrics and gynecology patients was higher than that of other departments.Conclusions The most common reason for AKI in hospitalized patients in Xinjiang was pre-renal injury.The main risk factors were low cardiac output and low blood volume.The omission diagnosis of AKI was serious;AKI stage,peripheral vasodilation and renal parenchymal injury however were its protective factors.Poor-DIC,shock,hospitalization in obstetrics were independent risk factors for death in patients with AKI.

Objective To investigate the effect of preoperative anxiety on propofol EC50 for nomovement during Painless gastroscopy.Methods Thirty-one patients (without anxiety) and twenty-seven patients (with anxiety) undergoing gastroscopy under general anesthesia were enrolled on the study.Anesthesia was conducted with a target-controlled infusion (TCI) of propofol.The initial target effect-site propo fol concentration (Ceprop) was 5.0 μg/ml and was adjusted stepwise by 0.5 μg/ml by an up-down sequential method to reach no-movement.Results Propofol EC50 to induce no-movement was higher in patients with anxiety than those without anxiety (5.32 μg/ml,95％ CI:4.75-5.88 μg/ml vs 4.75 μg/ml,95％ CI:4.48-5.01 μg/ml,P ＜ 0.05).Conclusions During painless gastroscopy,patients with anxiety had a higher propofol EC50 for no-movement compared with those without anxiety when intravenous injected of fentanyl 0.1 μg/kg.

Ferroptosis is a novel iron-dependent mode of programmed cell death characterized by iron deposition and accumulation of lipid peroxidation. More and more studies have found that ferroptosis is closely related to the pathogenesis of type 2 diabetes mellitus （T2DM）. The yin-fire theory is an important part of LI Gao's spleen-stomach theory， and it is believed that qi-fire imblance and yin-fire internal generation is the main pathogenesis of T2DM. Abnormal iron metabolism may be an important prerequisite for T2DM yin-fire internal generation， while oxidative stress is the specific manifestation of T2DM qi-fire imbalance. Reactive oxygen species （ROS） is the end product of qi-fire imbalance， and lipid peroxide is the pathological products of T2DM yin-fire internal generation. This study intends to explore the pathological mechanism of qi-fire imbalance and yin-fire internal generation from the perspectives of iron metabolism， oxidative stress and lipid peroxidation， enriching the modern connotation of yin-fire theory， and benefiting traditional Chinese medicine to target against ferroptosis， and prevent and treat T2DM precisely.
