OBJECTIVETo determine the diagnostic values of plasma CD64 and soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) in children with pneumonia.

METHODSSixty children with pneumonia between August 2014 and October 2015 were classified into bacterial pneumonia group (25 cases), viral pneumonia group (17 cases), and Mycoplasma pneumonia group (18 cases) according to their clinical manifestations, pathogen cultures, and X-ray findings. Another 30 healthy children who underwent physical examination during the same period were selected as the control group. The concentrations of CD64 and sTREM-1 in blood samples were determined using ELISA. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic sensitivity and specificity of plasma CD64 and/or sTREM-1 for bacterial pneumonia.

RESULTSThe expression of CD64 and sTREM-1 in the bacterial pneumonia group was significantly higher than that in the viral pneumonia, Mycoplasma pneumonia, and control groups (P<0.05). The areas under the ROC curves of CD64, sTREM-1, and a combination of the two markers for diagnosing bacterial pneumonia were 0.878, 0.805, and 0.956, respectively. The sensitivity and specificity of CD64 for diagnosing bacterial pneumonia were 81.30% and 92.32%, respectively, when the cut-off value was 641 pg/mL. The sensitivity and specificity of sTREM-1 for diagnosing bacterial pneumonia were 78.65% and 84.67%, respectively, when the cut-off value was 1 479 pg/mL. The sensitivity and specificity of a combination of the two markers for diagnosing bacterial pneumonia were 93.15% and 91.54%, respectively.

CONCLUSIONSPlasma CD64 and sTREM-1 can be used as markers for diagnosing pediatric bacterial pneumonia, and a combination of the two markers results in better diagnosis.

AIM:To compare the clinical effects of 25G+ and 27G+ transconjunctival sutureless vitrectomy in treating idiopathic macular hole.METHODS: We retrospectively reviewed the clinical outcomes of 56 eyes (56 patients) with idiopathic macular hole which were treated with micro-incision vitrectomy from June 2015 to September 2016.Patients were divided into two groups, 28 patients (28 eyes) were treated with 25G+ vitrectomy and the rest (28 eyes) were treated with 27G+ vitrectomy.The operative time and intraoperative complications were recorded and patients were followed up for 3-6mo.During the follow up period, best correct vision acuity (BCVA), intraocular pressure, macular hole healing and postoperative complications were documented and statistically analyzed.RESULTS: BCVA in two groups were significantly improved after surgery(P<0.001) and there was no significant difference between the two groups(P=0.84).No serious complications occurred.No statistically significant difference was found between the two groups in surgical time and healing rate of macular hole (P=0.57, 0.64).The incidence of low intraocular pressure (IOP<10mmHg) in 27G+ group was lower than that in 25G+ group on the first day after surgery(P=0.31).There was no significant difference between preoperative and postoperative intraocular pressure at 1wk after operation in both groups (P=0.72, 0.92).CONCLUSION: Both 25G+ and 27G+ vitrectomy are safe and effective technique in treating idiopathic macular hole.Besides, 27G+ showed better superiority on the maintenance of intraocular pressure and reduce the trauma.

The aims of microbiology experiment teaching are not only to cultivate the students’ capacity of basic operation,but also to expanse their knowledge scope.We applied the bacterial diversity on the teach-ing class to make the students understand the progress of microorganism genomics research.It is helpful to cultivate the students’ innovative spirit and ability.Easy to work,clear result and low cost facilitated the spread of this experiment in the university.

High price and poor stability of both crocin-1 and crocin-2 reference substance have become obstacles to HPLC assay of Croci Stigma. A new method based on reference extract was proposed. In this study, the reference extract was prepared from gardenia yellow which is cheap and easy to get The content of crocin-1 and crocin-2 in reference extract was determined and factors affecting stability of reference extract were investigated. Twelve batches of Croci Stigma were analyzed with reference extract and reference substance respectively. The results showed no difference. The presented method is feasible for quality control of Croci Stigma and reference extract is suitable to replace reference substances in assay.

To study the effect of pulchinenoside (PULC) on the Frizzled (FZD) expression of adjuvant arthritis ( AA) rats. AA rats were prepared through the toe injection with complete Freund's adjuvant to culture fibroblast-like synoviocytes (FLS). The effect of the oral administration with PULC on the FZD8 expression was detected by the real time qPCR. The effect of FZD8 knockout on the expressions of IL-1, IL-6, IL-8 were detected by MTT and ELISA. The role of miR-375 in the abnomal expression of FZD8 was detected by the real time qPCR. The results showed signfiicant decrease in the FZD8 expression among AA rats, FLS proliferation ater FZD8 knockout and IL-1, IL-6, IL-8 expressions and notable increase in miR-375 expression after the oral administration with PULC. The up-regulated miR-375 expression can inhibit the FZD8 expression. PULC may inhibit the FZD8 expression by up-regulating the miR-375 expression.

Objective To evaluate the feasibility of reconstructing horizontal periodontal bone defects by tissue engineering based on bone marrow stromal cells(BMSCs)as seed cells and enamel matrix proteins(EMPs)as growth factors. Methods Two healthy rhesus monkeys were selected, and BMSCs were isolated from iliac marrow and serial subcultivation was conducted. The cells of induced BMSCs at passage 3 were harvested and mixed with Bio-oss collagen. The models of horizontal periodontal bone defects were established surgically in each buccal side of the posterior teeth, and were divided into four groups (blank control group, material group, cells/material group and cells/material/EMPs group). The histological and Micro-CT observation were carried out 8 weeks later. Results In the blank control group, the defects were filled with fibrous connective tissue. There was newly-formed alveolar bone in the material group. In the cells/material group, periodontal regeneration could be observed, while the newly-formed cementum was irregular and less in quantity. In the cells/material/EMPs group, the amount of newly-formed alveolar bone was larger, and the newly-formed cementum was continuous and regular. Conclusion The tissue engineering technique of BMSCs as seed cells in combination with EMPs induction can significantly promote the regeneration of periodontal tissue.

Objective To explore the correlation between the change of regional cerebral blood flow (rCBF) and brain tissue injury from interictal epileptic activity in patients with epilepsy. Methods Fortyeight patients with epilepsy and 30 healthy persons were included in the styudy from which the serum S100β protein levels were determined by double antibody sandwich ELISA method. SPECT rCBF imaging was performed in all patients. The visal and semi-quantitative analyses were used to analyze the epileptic foci.SPSS 11.0 was applied for variance and linear correlation analyses. Results Serum S-100β in patients with interictal epileptic activity was significantly higher than that in control group ((0.572 ± 0. 163) μg/Lvs (0.218 ±0. 134) μg/L, t =9.96, P <0.01). According to epilepsy control criteria, 20 cases achieved complete control (CC), 18 cases acheived partial control (PR). However, 10 cases got no improvement,whose serum S-100β protein ((0. 809 ±0. 056) μg/L) and the percentage change of rCBF ((0. 337 ±0. 060) %) were significantly higher than those of CC ((0.443 ± 0. 083) μg/L, (0.035 ± 0.038) %) and those of PC ((0.585 ±0. 108) μg/L, (0. 187 ±0.075)%), F=56. 740, 92. 316, P <0.01. There were high correlation between serum S-100β and the percentage change of rCBF in epilepsy patients (r =0. 887,P<0.01). Conclusion Serum S-100β protein assay combined with rCBF on SPECT imaging can make semi-quantitative diagnosis of epilepsy and help evaluate the brain damage from interictal epileptic activity.
