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.

Objective To evaluate the value of haptoglobin (HPT),α1-acid glycoprotein (AAG)and C-reactive protein (CRP) in the differential diagnosis of bacterial and viral infection in children. Methods Serum CRP, AAG and HPT levels were measured in 64 children with bacterial infection and 64 children with viral infection during acute stage. These indicators were also measured in 31 normal control children. The sensitivity ,specificity ,positive and negative predictive values, Youden's index for HPT,AAG and CRP were calculated. These values were compared among three groups. Their early diagnostic value on bacterial infection and virus infection was evaluated. Results (1) These markers were considered positive if HP≥2 g/L,AAG≥2 g/L,CRP≥10 mg/L. (2) The serum CRP [(2.70 ±0.99) g/L vs (1.42 ±0.75) g/L] ,AAG [(0.91 +0.38) g/L vs (0.30+0.08) g/L] and HPT [(6.40 ±0.89) mg/L vs (1.38 +0.80) mg/L]levels were significantly higher in children with bacterial infection compared with those with viral infection during the acute stage (P ＜ 0. 05,P ＜ 0. 01). The serum CRP, AAG and HPT levels were significantly higher in children with bacterial infection compared with normal control children during the acute stage (P ＜ 0. 05);while the levels of these indicators showed no differences between viral infection children and normal control children (P ＞ 0. 05). Conclusion The measurement of serum CRP, AAG and HPT levels has clinical value in the differential diagnosis of bacterial and viral infection in children. Among these indicators, CRP has the highest specificity,positive predictive,negative predictive values and Youden's index.

Objective To evaluate the predictive value of morphology of superficial depression in estimation of histology and invasive depth in colorectal neoplasia by using magnifying chromo-endoscopy.Methods Flat or depressed and sessile eolorectal lesions which were indicated for endoscopic mucosal resection (EMR) were consecutively collected. Depressed lesions were classified into type 1 (star-like) and type 2 (round) according to the morphology of depressive areas in the colorectal neoplasia with magnifying ehromoendoscopy. The relationship between morphologic classification with histology and invasive depth was studied with reference to pathological diagnosis after EMR. Results Ninety lesions including 25 sessile and 65 flat were resected with EMR. Lesions with central depression (54. 4%,49/90) were more likely to have high-grade dysplasia (HGD) or cancer than those without ( 51.0% vs. 17. 1%,P＜0. 001 ). Depressive lesions of type 2 were more susceptible to have HGD or cancer than those of type 1 (89. 5% vs. 26. 7%,P＜0. 001 ). The overall accuracy of depression morphology for distinction between lesions of superficial submueosal (m-sm1) and deep submucosal (sm2-sm3) invasion was 83. 7% (41/49). Conclusion The morphology of superficial depression on colorectal neoplasia is highly correlated with the histology and invasive depth,which facilitates the EMR treatment.

Conclusion: Ablation catheter is feasible for arial lead restoration in patients with atrial lead dislodgement after pacemaker implantation.

Chimeric antigen receptor (Car) T cells, not only have the characteristics of strong specific recognition of tu-mor antigens, but also have destruction and high affinity advantages, thus receiving more attention. Although it has played a lot of advantages in anti-tumor, it still has some shortcomings, which needs to be further optimized to improve the safety of its clinical application. In this study, The cell structure and biological function, treatment process, application development and application risk of Car T cells are reviewed, which provide references for further clinical immunotherapy of Car T.

The objectives of this study are to prepare resveratrol loaded mixed micelles composed of poloxamer 403 and poloxamer 407, and optimize the formulation in order to achieve higher drug solubility and sustained drug release. Firstly, a thin-film hydration method was utilized to prepare the micelles. By using drug-loading, encapsulation yield and particle size of the micelles as criteria, influence of three variables, namely poloxamer 407 mass fraction, amount of water and feeding of resveratrol, on the quality of the micelles was optimized with a central composite design method. Steady fluorescence measurement was carried out to evaluate the critical micelle concentration of the carriers. Micelle stability upon dilution with simulated gastric fluid and simulated intestinal fluid was investigated. The in vitro release of resveratrol from the mixed micelles was monitored by dialysis method. It was observed that the particle size of the optimized micelle formulation was 24 nm, with drug-loading 11.78%, and encapsulation yield 82.51%. The mixed micelles increased the solubility of resveratrol for about 197 times. Moreover, the mixed micelles had a low critical micelle concentration of 0.05 mg · mL(-1) in water and no apparent changes in particle size and drug content were observed upon micelles dilution, indicating improved kinetic stability. Resveratrol was released from the micelles in a controlled manner for over 20 h, and the release process can be well described by Higuchi equation. Therefore, resveratrol-loaded poloxamer 403/407 mixed micelles could improve the solubility of resveratrol significantly and sustained drug release behavior can be achieved.

OBJECTIVE:To investigate the effects of Butylphthalide and sodium chloride injection on neurological function and prognosis of elderly patients with hypertensive intracerebral hemorrhage(HICH)after trepanation and drainage surgery. METH-ODS:During Jan. 2015 to Jun. 2016,80 elderly HICH patients were selected from our hospital and then divided into control group and observation group according to random number table,with 40 cases in each group. Both group received trepanation and drain-age surgery. Control group was given routine treatment. Observation group was given Butylphthalide and sodium chloride injection 100 mL,ivgtt,bid,on the fifth day after surgery,on the basis of control group. Both groups received treatment for 14 d. Clinical efficacies of 2 groups were observed. CSS scores were compared between 2 groups before surgery and 28 d after operation;volume of encephaledema,serum levels of homocysteine(HCY)and substance P(SP)were compared between 2 groups before surgery and 14 d after operation. RESULTS:The total response rate of observation group was 87.5％,which was significantly higher than 67.5％ of control group, with statistical significance (P<0.05). Before surgery, there was no statistical significance in CSS scores,volume of encephaledema or serum levels of HCY and SP between 2 groups(P>0.05). CSS scores 28 d after operation, SP levels 14 d after operation were significanthy increased,volume of encephaledema and serum levels of HCY in 2 groups were significantly decreased,and the observation group was significantly better than the control group,with statistical significance(P<0.05). CONCLUSIONS:Butylphthalide and sodium chloride injection can significantly improve clinical efficacy and hepatic func-tion damage,relieve postoperative encephaledema,reduce serum levels of HCY and increase SP levels in elderly HICH patients af-ter trepanation and drainage surgery.
