Medical Journal of Chinese People's Liberation Army 1983;0(02):-
The results of the determination of SACE activity in recent four years were reported. It was found that the levels were 33.5?5.1, 41.6?8.6, 33.4?8.6, 37.2?4.5, 53.6?7.3 and 31.4?13.0 in the healthy persons (37 cases), silicosis (40 cases), lung cancer (30 cases), pulmonary tuberculosis (18 cases), active sarcoidosis (4 cases) and inactive sarcoidosis (3 cases), respectively. The clinical value of the SACE measurement in sarcoidosis was discussed. The results showed that the SACE measurement is helpful to the diagnosis and monitoring of sarcoidosis, because the SACE activity was significantly elevated in most cases of active sarcoidosis, decreased during the stage of remission and elevated again during exacerbation. However, sarcoidosis can not be ruled out even though a normal SACE activity is measured. In addition, the SACE activity can also be elevated in the other pulmonary or systemic diseases, but the differentiation of these diseases from sarcoidosis is not difficult clinically. The SACE measurement can not be taken as a predictor of the prognosis of sarcoidosis.

Objective To explore the mechanism of latent human immunodeficiency ciency virus type 1 (HIV-1) infection is unclear, especially in dendritic cells (DC).We hypothesized that DC-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN) binds with HIV-1 may activate HIV-1 provirus.Methods We generated a model by transfecting 293T cells with a DC-SIGN expression plasmid and a HIV-1 5'long terminal repeat (LTR) reporter plasmid, and then stimulated the 293T cells with HIV-1 gp120 protein, wild-type HIV-1 and VSV-G-pNL4.3 pseudotype virus ( without gp120 protein).CEM-Bru cells were transfected with the DC-SIGN expression plasmid and stimulated by HIV-1 gp120 protein.Then HIV-1 replication was detected.The involvement of the ERK, p38 and NF-κB pathways signaling in this response were determined by inhibiting the pathways specifically and detecting the phosphorylation of the signaling kinase.Results The HIV-1 5'LTR was reactivated by HIV-1 gp120 in DC-SIGN-expressing 293T cells.After HIV-1 gp120 protein stimulation of the mold of CEM-Bru cells, the increasing expression of HIV-1 Tat mRNA and HIV-1 p24,which implies early and late HIV-1 provirus replication was reactivated by the HIV-1 gp120/DC-SIGN stimulation.HIV-1 gp120/DC-SIGN stimulation reactivates latent HIV-1 provirus via the NF-κB signal pathway.Conclusion HIV-1 gp120/DC-SIGN stimulation reactivates latent HIV-1 provirus via the NF-κB signal pathway.

OBJECTIVETo explore the impact of titanium implant on the growth and development of pediatric mandible after suffering from mandibular fracture and undergoing open reduction and internal fixation (ORIF) compared with those that underwent titanium plate removal postoperatively.
METHODSFifteen pediatric patients with mandibular fracture who underwent ORIF were included in this study. Eight patients did not undergo titanium implant removal postoperatively, whereas the other seven patients underwent the routine. The postoperative data of the pediatrics were collected for comparative analysis by taking the patients' frontal and lateral photos, recording the inter-incisor distance, and measuring the height of mandibular ramus, length of the mandibular body, and combined length of the mandible in three-dimensional reconstruction image.
RESULTSAll patients had acceptable facial contour, mouth opening, and occlusion, without obvious abnormalities. The radiography showed no significant difference between the bilateral mandibular lengths in the two groups of patients (P>0.05).
CONCLUSIONThe titanium plants have no significant impact on the growth and development of pediatric mandible postoperatively; hence, the question on whether the titanium plates should be removed or not may be neglected. The removal operation may lead to secondary trauma; thus, performing titanium plate removal routinely is not recommended.

Objective To investigate the effect of Candida albicans and its components on the expression level of human beta-defensin-2 mRNA (HBD-2) in keratinocytes in vitro. Methods Different components of Candida albicans were isolated by lyticase, repeated freezing and thawing, sonication, and centrifugation. The keratinocytes and HaCaT cell lines were co-cultured with Candida albicans and its cellular components for 24 h. The expression level of HBD-2 mRNA was detected by reverse-transcription polymerase chain reaction (RT-PCR). Results Low expression level of HBD-2 mRNA in the unstimulated keratinocytes and HaCaT cells was detected. The HBD-2 mRNA expression levels in the keratinocytes stimulated by Candida albicans, the extract of its cell wall, and pure mannan were significantly increased (P 0.05). Conclusions Candida albicans, the extract of cell wall of Candida albicans, and commercial mannan can increase the expression level of HBD-2 mRNA in keratinocytes.

OBJECTlVE To study the reIationship between microRNA(miRNA)-122 and Iiver injury in-duced by anti-tubercuIosis drugs,and to discover the new biomarkers for earIy diagnosis of this type of Iiver injury. METHODS mice were given 2 mL isoniazid oraIIy at 90 mg·kg-1 . BIood and Iiver tissue sampIes were coIIected at 1,3,5,7,14,21 and 28 d after administration of isoniazid. Serum gIutamic-pyruvic transaminase( GPT)and gIutamic-oxaIoacetic transaminase( GOT)IeveIs were determined using an automatic biochemicaI anaIyzer. Cu/ Zn-superoxide dismutase( Cu/ Zn-SOD ) activity and maIondiaIdehyde( mDA)content were detected by biochemicaI method. ReaI-time qPCR was used to measure the expression of miRNA-122. RESULTS GPT and GOT IeveIs were significantIy higher at 14 and 21 d(P﹤0.05)than in the controI. Cu/ Zn-SOD began to decIine whiIe mDA began to increase after 5 d(P﹤0.05). miRNA-122,which progressiveIy decreased after administration,was reduced to the mini-mum 0.58 ±0.02 at 14 d. There were good correIations between miRNA-122 and GPT,Cu/ Zn-SOD, mDA(the correIation coefficients were -0.370,0.268,and -0.298,respectiveIy),but no correIation with GOT was observed. CONCLUSlON The tissue miRNA-122 profiIe can be used as a sensitive marker for anti-tubercuIosis drug-induced Iiver injury,which couId contribute to the earIy diagnosis of Iiver injury.
