International Journal of Pediatrics 2017;44(7):478-482
HCMV infection can cause hepatopathy,pneumonia,diarrhea,thrombocytopenic purpura,and sensorineural hearing loss(SNHL),with high morbility and mortality.pp65(phosphoprotein 65),a major constitutive protein of virion,is closely associated with viral gene expression,immune evasion and cell metabolism.pp65 antigenemia level has positive correlation with clinical symptom,which can guide the preemptive therapyand improve prognosis,is considered as one of the golden standard methods of active cytomegalovirus infection.In this paper,the pp65 protein properties,pathogenesis,application in diagnosis and prevention are reviewed.
2.ELECTRON MICROSCOPIC OBSERVATION ON THE EFFECT OF ACUPUNCTURE ANALGESIA ON THE ULTRASTRUCTURE OF SYNAPSES OF CAUDATE NUCLEUS
Acta Anatomica Sinica 1953;0(01):-
The ultrastructures of synapses in the head of caudate nuclei of rats were studied by means of electron microscopic technique. The experimental group of rats, in which the pain threshold was elevated after electro-acupuncture, showed no change of the number of the granular vesicles, but a significant decrease of the number of clear synaptic vesicles (without dense core) in the presynaptic boutons. This might be correlated to release of acetylcholine in the synapse.

The stimulate effects of synthetical endogenous peptides, tuftsin (Tuf) and thymopentin(TP5), on phagocytic function were studied. After subcutaneous administration (sc) of Tuf, thelysozyme content in both M? and sera, and the acid phosphatase activity in M?, were increasedin a dose-dependent manner. The peak time of serum lysozme level following a sigle sc injectionof Tuf was about on the 6th day. The elevation of lysozyme in sera was delayed and enhancedstrongly by Freund incomplete adjuvant (FIA). In cylcophosphamide (Cy) treated mice,TP5further increased both lysozyme content amd acid phosphatase activity in M?activated byCy, and recovered the lysozyme level in spleen inhibited by cy. The results suggested thatTP5could not only activate the funceion of M?, but recover the number of M?decreased by im-mumoimhibitant.

OBJECTIVE:To explore the clinical efficacy and safety of Yunkang granule combined with dydrogesterone in the treatment of early threatened abortion. METHODS:128 patients with early threatened abortion were randomly divided into single drug group and combined medication group,64 cases in each group. Single drug group received Dydrogesterone tablet with first dose of 40 mg,then 10 mg,q 12 h until vaginal bleeding;combined medication group additionally received 8 g Yunkang granule, tid,until symptoms disappeared. Human chorionic gonadotropin (HCG),clinical symptoms remission time and disappearance time,pregnancy/childbirth complications,pregnancy outcome and neonatal adverse outcome,and the incidence of adverse reac-tions in 2 groups were compared. RESULTS:After treatment,HCG in 2 groups significantly increased,and combined medication group was higher than single drug group,the differences were statistically significant(P<0.05);clinical symptoms remission time and disappearance time in combined medication group were shorter than single drug group,the difference was statistically signifi-cant (P<0.05). There were no significant differences in incidence of pregnancy/childbirth complications,pregnancy outcome and neonatal adverse outcomes in 2 groups (P>0.05). The incidence of adverse reactions in combined medication group was 10.9%, which was significantly lower than single drug group (40.6%),the difference was statistically significant (P<0.05). CONCLU-SIONS:Both dydrogesterone alone and Yunkang granule combined with dydrogesterone show good efficacy in the treatment of ear-ly threatened abortion,but the remission time and disappearance time of clinical symptoms and adverse reactions in combined medi-cation group are less than that in single drug group.
