1.Re-evaluation on perinatal screening of TORCH
Chinese Journal of Laboratory Medicine 2008;31(7):742-746
TORCH infection during pregnancy is a group of infectious diseases resulting from viruses and other microorganisms. According to the past over 20-year experiences in serum screening in China, several infections which should be performed in the first trimester, or even much earlier in pregnant period, are hepatitis B, syphilis, HIV, and these three infections are confirmed to be harmful to the fetus or infants and also diagnostic methods and treatment are available. Screening for rubella should be better performed before conception and no specific management is required with IgM+, while immunization is recommended before pregnancy with IgM-. Screenings for cytomegalovirus, toxoplasmosis and herpes virus are not recommended. Scnography is warranted if fetal abnormalities were resulted from the above infections and amniocentesis or cordocentesis might be required for further investigations.
2.Recent advances in microglia activation and intervention mechanism in diabetic retinopathy
Recent Advances in Ophthalmology 2017;37(9):890-893
Diabetic retinopathy (DR) is one of the most significant microvascular complications of diabetes,and its incidence increases with the prolongation of DM;meanwhile,it can lead to severe vision loss.Recently,the pathogenesis of DR has been one of the focuses both at home and abroad,but the basic mechanisms are not fully elucidated.More and more scholars believe that DR may be a chronic and low degree of inflammatory response.Moreover,it is well established that microglia is a monocyte-macrophage,with antigen-presenting function.Especially in the retina,as microglia is activated,followed by the release of a large number of inflammatory factors,microglia involves in DR inflammatory response.Understanding the activation mechanism of microglia can provide a new perspective for the prevention and treatment of DR.Therefore,recent advances in activation of microglia in diabetic retinopathy and its intervention mechanism will be reviewed in the article.

As one of the serious complications of diabetes, diabetic retinopathy( DR) has become a main eye disease which causes blindness. The occurrence and development of DR is related to many factors. The pathogenesis is complicated, and the mechanism has not been clear. Early data suggest that the occurrence and development of DR has relations with many factors such as blood sugar level, diabetes duration and the environment. Among the factors, mitochondrial dysfunction and oxidative stress is the important mechanisms of DR and has become research focus in recent years. Consequences of mitochondrial dysfunction within cells include elevation of the rate of reactive oxygen species( ROS) production due to damage of electron transport chain proteins, mitochondrial DNA ( mtDNA ) damage, and loss of metabolic capacity. Clear understanding on the mechanism of mitochondrial functional change under high sugar level and oxidative stress response in the occurrence and development of DR is of great significance on prevention and cure of DR. ln this article, the development of mitochondrial metabolism and oxidative stress of DR is reviewed.

Objective To evaluate the effects of dexmedetomidine on the hemodynamics and the heart rate variability(HRV)in patients under-going lower limbs operations with application of tourniquet. Methods Forty patients undergoing lower limbs operations with application of tourni-quet were randomized assigned to dexmedetomidine group(group D,n=20)or control group(group C,n=20). After combined spinal-epidural anesthesia,group D received a continuous infusion of dexmedetomidine(0.5μg/kg for 10 min for loading dose and followed by 0.2μg·kg-1·h-1) until tourniquet deflation. The control group received normal saline instead. Mean arterial pressure(MAP),heart rate(HR),saturation of pulse ox-imetry(SpO2),low frequency power(LF),high frequency power(HF)and LF to HF ratio(LF/HF)were recorded at regular time points:imme-diately before loading dose(T0),before tourniquet inflation(T1),15 min after tourniquet inflation(T2),30 min after tourniquet inflation(T3),45 min after tourniquet inflation(T4),60 min after tourniquet inflation(T5),1 min after tourniquet deflation(T6),5 min after tourniquet deflation (T7)and 10 min after tourniquet deflation(T8). Results Compared with T0,the MAP of group D significantly decreased at T6-T8(P<0.05). Compared with T0 and T1,the MAP of group C increased at T2-T5(P>0.05). Compared with T2-T5,the MAP of group C significantly decreased at T6(P<0.05). Compared with group C,the MAP of group D significantly decreased at T6 and T7(P<0.05). Compared with T0,the HR of group D significantly decreased at T1-T8(P<0.05). Compared with T0,the HR of group C had no significant change at T1-T5(P<0.05). Compared with T1-T5,the HR of group D and group C significantly increased at T6(P<0.05). Compared with group C,the HR of group D significantly decreased at T1-T4 and T6(P<0.05). Compared with T0,the SpO2 of group D and group C significantly decreased at T6(P<0.05). Compared with group C,the SpO2 of group D significantly decreased at T1-T3(P<0.05). Compared with T6,LF of group D and group C significantly increased at T7(P<0.05). LF were comparable between groups D and C(P>0.05). Compared with T0,the HF of group D significantly increased and the LF/HF of group D significantly decreased at T1-T4(P<0.05). Compared with group C,the HF of group D significantly increased and the LF/HF of group D significantly decreased at T1-T4(P<0.05). Conclusion The appropriate dose of dexmedetomidine(loading dose 0.5μg/kg and maintenance dose 0.2μg · kg-1 · h-1)can significantly increase vagal tone and improve cardiac sympathetic and parasympathetic balance during tourniquet appli-cation.
