There were Eye 1 (MA-L), Eye 2(MA-L), Liver (MA-SC 5) and Er Shenmen (MA-TF 1) in the first group and Central rim (MA-AT), Eye(MA-L 1), Superior Triangular Fossa (MA-TF) and Cervical Vertebrae (MA-AH 8)points. Then the cervical vertebrae were plucked and moved fore-and-aft circlewise. The result showed that among 45 affected eyes of the 35 cases, the total effective rate was 97.8%, which indicated the therapeutic effect was remarkable.

Objective To evaluate the efficacy and safety of immunosuppressive strategy of leflunomide (LEF) combined with calcineurin inhibitor and prednisone in Chinese renal transplant recipients.Methods Prospective clinical study was performed in 16 stable renal transplant recipients treated with calcineurin inhibitor, prednisone and either mycophenolate mofetil (MMF) or azathioprine (Aza), and MMF or Aza was replaced by LEF afterward. The loading dose of LEF was 50 mg/day for 3-5 days, and the maintenance dose was 20 mg/day. Prednisone was maintained 10 mg/day. The doses of CsA were adjusted according to its blood concentration.Results One patient dropped due to economic reason 1 mouth later, and continued to take Aza. Another one patient switched back to MMF due to a slight increase of serum creatinine (from 130 ?mol/L to 143 ?mol/L) 6 months after conversion. The remaining 14 patients were still on LEF. The mean observation time under LEF was (8.7?7.2) months (1～18 month). The mean serum creatinine was (103?24) ?mol/L before conversion, (95?26) ?mol/L at 6th month, and (108?27) ?mol/L at one year post-conversion. There was one episode of biopsy proved reversible acute rejection. The observed side effect was tolerable alopecia in 2 cases and rash in 1 case, but there were no significant increases in liver function, decrease of blood WBC count, deterioration of anemia, or any serious infection in any of the patients.Conclusion Immunosuppressive strategy of LEF+calcineurin inhibitor and prednisone is effective and safe in stable Chinese renal transplant recipients.

Objective To investigate how to prevent deep-vein thrombosis(DVT) after total knee replace-ment(TKR).Methods Deep vein thrombosis in 87 patients after TKR from 2004 to 2007 in the Third Hospital Affiliated to Suzhou University was retrospectively analyzed.Results Amony the 87 patients,13 were found having deep vein thrombosis,5 of 38 using low-molecular-weight beparin after TKR having deep vein thrombosis,6 of 35 cases using aspirin after TKR having deep vein thrombosis,5 of the 10 eases using mechanical preventive measures having deep vein thrombosis.The difference between low-molecular-weight heparin and aspirin group was not statistically significant.Conclusion Using low-molecular-weight heparin before TKR can prevent the occurrence of deep-vein thrombosis.Using epidural anesthesia,and a low-molee-ular-weight heparin drugs or aspirin after TKR can better prevent the formation of deep-vein thrombosis.

Objective:To explore the association between different urbanization levels and non-commu-nicable diseases (NCDs)in China and provide suggestions on designing relevant health policies in the ur-banization process.Methods:We obtained health-related data from China Health and Retirement Longi-tudinal Study (CHARLS)201 1 .This study used multistage sampling in design stage and covered 1 50 districts/counties,representative at the levels of the country.Geo-information system (GIS)method was used to get district areas data,and in combination with the Sixth National Census population data,we computed the population density which was regarded as the proxy variable of urbanization level in every city.The Logistic model was used to explore the effect of urbanization level on hypertension,diabetes, smoking,drinking,overweight and obesity.Results:Compared with other cities in China,Shanghai and Shenzhen,with the population density of more than 3 000 people per km2 ,were the cities with highest urbanization level.From the map of urbanization distribution across China,it was found that the urbani-zation levels of the northwestern districts were lower than those of the southeastern and coastal districts. The hypertension rate increased with the development of urbanization but there was no statistical signifi-cance.The proportion of patients with diabetes went up first and then saw a decrease trend in the process of urbanization.Drinking rate,overweight rate and obesity rate had similar trends,falling to their lowest point when urbanization level equaled 737,1 1 86 and 1 353 people per km2 respectively and then ex-perienced upward trends.By contrast,smoking rate declined first and then went up (the turning point was 1 029 people per km2 ).Conclusion:Different urbanization levels have different effects on NCDs, health-related behavior,overweight and obesity.Low urbanization level may create negative impact on health while high level can pose positive effect and increase people’s health condition possibly due to the improvement of health care accessibility and the quality of living environment.Policy-makers should spe-cially focus on different residents’health problems in different periods of urbanization,such as the impact of environmental pollution,health resources’allocation and accessibility of health services.It is necessa-ry to reduce or avoid the negative effect of urbanization on NCDs during the local development process to face the NCDs’threat.

Objective To investigate the effect of cerebral ischemic preconditioning (IP) on the expressions of angiopoietin-1 (Ang-1) and its receptor Tie-2 mRNA in cerebral ischemia in rats.Methods Ninety-nine Wistar rats were randomly assigned to three groups:sham operation (n =9),non-ischemic preconditioning (NIP) (n =45),and IP (n =45).The latter two groups were redivided into 5 subgroups:ischemia-reperfusion 1,3,7,14,and 21 days (n =9 in each group).A model of transient middle cerebral artery occlusion (MCAO) was induced by the intraluminal suture method for focal IP (ischemia for 10 minutes and restoring perfusion).Infarct volume was determined by 2,3,5-triphenyltetrazolium staining.The expression levels of Ang-1/Tie-2 mRNA were detected by in situ hybridization.Results The infarct volumes in the 1 -,3-,and 7-day subgroups of the IP group were significantly smaller than those in the relative subgroups of the NIP group (all P＜ 0.05).The expression of Ang-1 mRNA in the 3- and 7-day subgroups of the IP group and the expression of Tie-2 mRNA in the 1-,3-,and 7-day subgroups of the NIP group were upregulated significantly (all P ＜ 0.05).The infarct volume in the 3-day subgroup of the IP group was reduced most significantly (P ＜ 0.05).The expression of Ang-1 mRNA in the 7-day subgroup was upregulated significantly,and the peak expression of its receptor Tie-2 mRNA appeared at day 3 after IP and continued to day 7.Pearson correlation analysis showed that the expression levels of Ang-1/Tie-2 mRNA were significantly negatively correlated with infarct volume (P ＜0.01).Conclusions The expression of Ang-1/Tie-2 mRNA in the IP group was upregulated within the time window of ischemic tolerance (1 - 7 days after preconditioning),in which Ang-1 may mainly act on the later stage of the cerebral ischemic tolerance.
