Objective To explore the relationship of monocyte chemoattractant protein-1(MCP-1)and oxygen-induced retinopathy(OIR).Methods Thirty-six newborn SD rats were divided into 2 expanded litters,18 of which were exposed to 50 mL/L oxygen and then 10 mL/L oxygen in alternating 24-hour periods(experiment group),an additional 18 rats as control rats were raised simultaneously in room air(control group).On postnatal 14 days(P14),oxygen-exposed rats were removed to room air.The eyeballs of 6 rats from each group were enucleated and fixed by formaldehyde at postnatal 14 days(P14),postnatal 17 days(P17),and postnatal 21 days(P21)respectively,and then cross sectioned.The nuclei of proliferative retinal vessels were counted through the crosssections to measure the average retinal capillary density index(RCDI)when stained with hematoxylin and eosin(HE)under light;the expression of MCP-1 was measured by immunohistochemistry.Results There existed obviously differencc between 2 groups in the field of both RCDI and the expression of MCP-1 at the same time point [t(P14)=6.69 P=0.001,t(P17)=3.43 P=0.006,t(P21)=2.37 P=0.039;t(P14)=40.45,t(P17)=43.44,t(P21)=17.45 Pa=0],when RCDI and the expression of MCP-1 were compared among the different time points with in the same group,there existed obviously difference among three time points in the experiment group(F=17.74 P=0.0001;F=421.5 P=0),but no differencc in control group(F=0.016 P=0.984;F=0.006 P=0.994).There existed positive correlation between the expression of MCP-1 and the value of RCDI in experiment group(r=0.822 P=0).Conclusions Neovascularization resulting from OIR occurs before room air recove-ry.MCP-1 is upregulated and subsequently downregulated in OIR.Neovascularization in the OIR model appear to be associated with increased retinal MCP-1.

Objective To evaluate the clinical effects of emergency neoplasty on corneal penetrating injury. Methods A total of 102 cases of corneal penetrating injury were investigated.The patients underwent micro-trauma technique suture,optical iridectomy,extraction of anterior segment foreign bodies,nepheloid lens removal,and artificial lens implantation.The vision of pre-and post-surgery was compared and relationship between injury location and recovery was analyzed. Results The injury of cornea repaired completely 1 month after surgery.Cross infection was not found in the patients with one-year long follow-up(80% of all patients).The vision of all patients raised.The injury in center and nasal side affected vision significantly. Conclusion Timely surgery to corneal penetrating injury may be considered in order to improve the recovery of the traumatic eyes.

Objective To understand the prevalence and Influencing factors of Metabolic Syndrome(MS) of 40~74 year-old non-diabetes population in Minhang District.Methods A population-based sample(diabetes screening of Minhang District in 2007) of 3 947 individuals aged 40~74 years was investigated by cluster random sampling.They completed a questionnaire and underwent triglyceride,high density lipoprotein measured cholesterol and an oral glucose tolerance test.Results The standardized prevalence rate of MS,overweight,diabetes,impaired glucose regulation(IGR),hypertension,high triglyceride and low HDL were 15.67%,2.45%,5.60%,17.72%,16.47% and 2.00%.The male with MS,overweight or obese,diabetes and hypertension were higher than the female in terms of incidence.The prevalence of MS was increased with age,the highest rate at the ages of 50 years and above.There was no significant difference between male and female at the ages of 45 years and above.The incidence of MS in people with BMI or hypertension or abnormal blood glucose or hige TG or low HDL-C was obviously higher than that of normal population.The OR value were 15.71,28.21,10.09,30.31 and 3.14 respectively.The prevalence of diabetes,coronary heart disease and stroke in people with MS was higher than that of people with out MS.The OR value were 10.09,9.94 and 2.40.Multiple factor analysis showed that the factors related to MS were male,the aged,family history of diabetes and having no physical activity.Conclusions MS and realated diseases are a serious threat to population of 40 years old and above in Minhang District.

The effects of betulinic acid (BA), a pentacyclic lupane-type triterpene, on the cell viability, cell cycle and apoptosis in human leukemia K562 cells were investigated. The effects of BA on the growth of K562 cells were studied by MTT assay. Apoptosis was assayed through Annexin V/propidium iodide (PI) double-labeled cytometry. The effects of BA on the cell cycle of K562 cells were studied by a PI method. The expression of Bax and capase-3 was detected by using Western blot. The results showed that BA was cytotoxic to K562 cells with an IC(50) of 21.26 mug/mL at 24 h. After treating K562 cells with 10 mug/mL BA for 72 h, the number of cells was reduced by 58%. BA induced apoptosis of K562 cells in a time- and dose-dependent manner. The proportion of cells in G(0)/G(1) and G(2)/M phases was decreased and that in S phase was increased after K562 cells were treated with BA for 24 h. BA treatment also increased the expression of the pro-apoptotic proteins Bax and caspase-3. It suggested that BA could inhibit the proliferation of K562 cells through the induction of cell cycle arrest and apoptosis. The antitumor effects of BA were related with up-regulation of the expression of Bax and caspase-3 proteins. BA may qualify for the development of new therapies for leukemia.

Objective To study the factors influencing the curative effect of one-stage bihteral total hip arthroplasty in a sequential procedure.Methods Thirty-six patients were indicated for one-stage bilateral total hip arthroplasty from February 1998 to March 2008.All cases were made with Smith-Peterson incision.Results The operative time was(3.2±1.2)h.The volume of blood transfusion during operation was (620 4±120)ml.All the 36 patients were followed up for(22.0±6.0)months.Except for 1 case of deep venous thrombosis of lower limbs,1 case of limb length discrepancy,there were no severe complications,such as postoperative infection,pulmonary embelism,dislocation,loosening or subsiding of components.Postoperative Harris scoreg of the joint function[(88.0±3.6)points]was significantly improved compared with their preoperative Harris scores[(28.0±4.2)points](P<0.05).Conclusions One-stage bilateral total hip arthroplasty is an effective method.However.the satisfactory effects can only be achieved by strict case selection,sufficient preoperative preparation,attention to operation procedures,prevention of complications and active recovery after operations.

ObjectiveTo investigate the test-retest reliability and inter-rater reliability of ASIA2000 scale.MethodsTwenty-five hospitalized spinal cord injury volunteers were chosen according to the selective criteria. The items were retested by the same examiner one week later to determine the scale's test-retest reliability. Another doctor did the same work 24 h later to determine the scale's inter-rater reliability.ResultsThe Pearson correlation coefficients of the pin prick score, light touch score and motor score of the test-retest reliability were all above 0.90 (P<0.05), and the Kappa values of the ASIS impairment scale (AIS) and completeness of the injury were 0.787 and 0.756 (P<0.05). The Pearson correlation coefficients of the pin prick score, light touch score and motor score of the inter-rater reliability were all above 0.85 (P<0.05), and the Kappa values of the AIS and completeness of the injury were 0.802 and 0.764 (P<0.05).ConclusionThe ASIA2000 scale has good test-retest reliability and inter-rater reliability.

ObjectiveTo investigate the application of ASIA2000 classification in prognosis of spinal cord injury patients' neurological function. MethodsConsecutive observation was done to the 42 patients using ASIA2000 classification 1 month, 3 months and 12 months after injury respectively. ResultsTo the incomplete SCI patients, motor score, pin prick score and light touch score were significantly improved 3 months after injury compared with that in 1 month after injury (P<0.05), but no significant improvement was observed in the complete ones, nor did in all the patients between 3 months and 12 months after injury. ConclusionThe Standard Neurological Classification is more sensitive than Standard Impairment Classification in ASIA2000. Individuals within 3 months after injury got better neurological recovery than those more than 3 months after injury. Incomplete injuried individuals may get better neurological prognosis than complete ones.
