Totally 1136 individuals aged over 40 underwent health check up in March to May 2009. Fasting blood glucose, 2-h post-challenge blood glucose, glycated hemoglobin A1c ( HbA1c), total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and serum uric acid were measured. The diagnosis of metabolic syndrome was based on the International Diabetes Federation Criteria. The results shows that total body fat, region body fat indices, blood pressure, blood glucose and serum uric acid levels increased with the age ( P < 0.01) . The prevalence rate of metabolic syndrome in this group of individuals were 15. 1% (171/1136) , and increased with age (P<0.01). The most common combination of metabolic syndrome was central obesity-hypertension-dyslipidemia (40. 9% , 70/171). Unconditional logistic regression revealed that waist-hip-ratio, body mass index and uric acid were the risk factors for metabolic syndrome.

Objective To summarize our experience in the diagnosis and management of popliteal artery entrapment syndrome (PAES). Methods This is a retrospective study on 10 patients (13 limbs)who were admitted for symptoms of claudication and the diagnosis of popliteal entrapment was established either with angiography,computed tomographic angiography,magnetic resonance angiogram or during the operation in recent 7 years (2002-2009).All patients were treated surgically. Results The mean age at the time of presentation was (25 ±7) years old (range,17-41 years).Claudication was the most frequent presenting symptom (12 limbs).The surgical procedures consisted of simple musculotendinous dissociation in 1 limb,thrombectomy with balloon angioplasty in 1 limb,musculotendinous dissociation plus thromboendarterectomy with autogenous saphenous vein (ASV)patch angioplasty in 2 limbs,ASV graft interposition or bypass in 6 limbs and graft interposition or bypass in 3 limbs.At a median follow-up of (35 ±27) months (range,2 months-7 years),there were no intraoperative or long-term postoperative complications and all the patients were cured. Conclusions PAES is an unusual but important cause of peripheral vascular insufficiency especially in young patients.A combined approach is necessary for diagnosis.Popliteal artery release alone or with vein bypass or reconstruction is the treatment of choice.

The human cytomegalovirus (HCMV) is a widespread herpesvirus. Virus reactivation from latency can lead to stillbirth, miscarriage, fetal anomalies, and intrauterine growth retardation. During latent infection with the HCMV, the virus can be cleared by the immune response or apoptosis of host cells. However, the HCMV has developed several strategies to manipulate expression of its genes and the microenvironment of host cells. Recent studies have shown that latent infection with the HCMV is associated with viral: regulation of early expression of genes; evasion of cell death; evasion of the immune response; regulatin of non-coding RNAs. This review summarizes recent research progress on the mechanisms underpinning latent infection with the HCMV.

AlM: To evaluate the application of phacoemulsification of different nucleus density using ozil and traditional mode.METHODS: A total of 89 eyes (72 patients ) ( visual acuity was of 0. 6 and above after 1mo follow - up) of different nucleus density level (LOCS Ⅱ criteria grade Ⅲ 46 eyes, grade Ⅳ and more 43 eyes ) were randomly assigned into 2 groups: ozil group (group A), grade Ⅲ 22 eyes (torsional energy 80% lP on);grade Ⅳ and more 17 eyes (torsional energy 100% lP on); Traditional mode group(group B), grade Ⅲ 24 eyes (energy 50% ), grade Ⅳ and more 26 eyes (energy 60% ~ 70% ) . All surgeries were performed by the same experienced surgeon,who use the chop to split the nucleus in the application of phacoemulsification. lntraoperative parameters were total equivalent pawer ( TEP ), cumulative dissipated energy ( CDE ) and effective phaco time ( EPT ) and surgical complications. The effectiveness of the two modes in dealing with hard - core cataract phacoemulsification were compared.RESULTS: GradeⅢ nucleus dealing: TEP of ozil group was significantly higher than that of the traditional mode group [(24.58±7.78)% vs (13.84±1.97) %]and EPT of ozil group was significantly lower than that of the traditional mode group (50. 59±14. 73 s vs 60. 19±9. 04 s, P<0. 05). CDE showed no difference between two groups [(13.12±6.03)% vs (13.38±2.85)]. Grade Ⅳ and more nucleus dealing: CDE [( 34. 10 ± 13. 48 )%] and EPT (104. 64±32. 4s) of the ozil group was higher than CDE [(30. 31 ± 13. 48)%] and EPT (93. 01 ± 41. 01s) of the traditional mode group, but there were no difference between two groups. Obstacles in the needle of phacoemulsification surgery: ozil group 4/17, traditional mode group 2/26 (χ2=2. 16, P=0. 14).CONCLUSlON: Bothozil and traditional mode can deal with all kinds of nucleus effectively and safely. Ozil mode is more efficacy and quick deal in gradeⅢnucleus. With the increase of nucleus hardness, the traditional mode still have the advantage of high efficiency and no obstacle to dealing patients with grade Ⅳ and more nucleus. Choose according to different nuclear hardness ultrasonic model can improve the operation efficiency and security.
