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.

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.

Objective To evaluate the efficacy and safety of the combination of Weimaining capsule and XELOX regimen (oxaliplatin plus capecitabine) in the treatment of advanced gastric cancer patients.Methods A total of 62 patients with advanced gastric cancer who fulfilled all predetermined criteria were randomly divided into observation group and control group.The 31 patients in observation group received a combination of Weimaining capsule and XELOX regimen,the 31 patients in control group received only XELOX regimen at the same dose intensity.Each patient received at least two cycles (1 cycle =21 days) of treatment,the efficacy was assessed after two cycles.Results The median time-to-progression (TTP) of observation and control groups were 5.5 and 4.8 months,respectively.The difference had no statistical significance (P =0.238).The disease control rates (DCR) of observation group was significantly improved compared with control group [67.7 ％ (21/31) vs 41.9 ％ (13/21),P ＜ 0.05],the difference was statistically significant,while the objective response rate (ORR) of the 2 groups had no statistical difference [(32.3 ％ (10/31) vs 25.8 ％ (8/31),P ＞ 0.05].In drug safety aspects,there was no Ⅴ grade adverse reactions (deaths caused by drug) among all the patients.Rates of grades Ⅱ-Ⅳ neutrocytopenia and nausea,vomiting in observation group were obviously lower than control group [16.13 ％ (5/31) vs 38.71％ (12/31),P ＜ 0.05;12.90 ％ (4/31) vs 35.48 ％ (11/31),P ＜ 0.05],other adverse reactions between the 2 groups had no statistical difference.Conclusions A combination of Weimaining capsule and XELOX regimen in the treatment of advanced gastric cancer patients can improve DCR significantly and reduce part of adverse reaction induced by chemotherapy with satisfactory safety.This method is worthy of application widely.

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.
