Abstract
Objective: To study the effect of various concentrations of Enterococcus faecalis (Ef) supernatants on human periodontal ligament cell (hPDLC) and the inflammatory response of hPDLC under static pressure. Methods: The method of methyl thiazolyl tetrazolium (MTT) was used to detect the effect of various concentrations of Ef supernatants on the proliferation of hPDLCs and the flow cytometry was used to detect the expression of Toll-like receptor 2 (TLR-2) on the surface of hPDLC after 24-hour-stimulation of Ef supernatant. Furthermore, the hPDLCs were divided into non inducing group without Ef supernatant and inducing group with 5% Ef supernatant, and hPDLCs in each group were loaded with 0, 49 and 196 Pa static pressures respectively. The expressions of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) mRNA and protein were detected by reverse transcription-PCR (RT-PCR) and enzyme linked immunosorbent assay (ELISA) after 24 hours. Results: MTT results showed that the supernatant of Ef with concentration≥5% could significantly inhibit the proliferation activity of hPDLCs at 48 hours of cell culture (P<0.05). Flow cytometry showed that the positive cell rates of TLR-2 increased with increasing volume fractions of the Ef supernatants. The values were (2.12±0.07)%, (2.41±0.32)%, (2.65±0.27)%, (4.76±0.46)%, (9.91±0.92)% and (12.01±1.35)%, respectively. The differences were statistically significant when the concentrations≥5% (P<0.05). There were no significant differences in the expressions of IL-1β and TNF-α mRNA between the non inducing group and the control group under the pressure of 49 Pa (P>0.05). However, there were significant differences in the expressions of IL-1β and TNF-α mRNA between the non inducing group and the control group under the pressure of 196 Pa (P<0.05), while the expressions of IL-1β and TNF-α in the inducing group were significantly lower than that in the control group under the pressures of 49 and 196 Pa (P<0.05). Compared with the control group, the mRNA expression was significantly increased (P<0.05). The result of ELISA was consistent with that of PCR. Conclusions: High concentration of Ef supernatant could inhibit the proliferation of hPDLC. Ef supernatant might promote the expression of TLR-2 on the surface of hPDLC. Excessive mechanical pressure induced the inflammatory response of hPDLC. The presence of inflammatory mediators could lead to the intolerance of hPDLC to pressures and small pressure could aggravate the inflammatory response.

Abstract
目的 评估伊马替尼对慢性髓性白血病慢性期(CML-CP)儿童身高的影响。 方法 2018年7月至2019年7月,在全国范围内对诊断时年龄<18周岁、接受伊马替尼治疗至少3个月的CML儿童或其家长发放问卷,调查受访者伊马替尼治疗前后身高的变化。主要评价指标为身高标准差积分值(HtSDS)以及标准差积分的差值(ΔHtSDS),并分析其相关影响因素。 结果 共有238例受访者符合标准并被纳入研究,男性138例(58.0%),初诊时中位年龄11.0(1.4~17.9)岁,青春期前93例(39.0%),至填写答卷时,中位年龄15.0(2.0~34.0)岁,中位伊马替尼服药时间28(3~213)个月。受访者填写答卷时HtSDS(−0.063±1.361)较治疗前HtSDS(0.391±1.244)显著下降(P<0.001),71.0%的患儿出现身高增长减慢。青春期前服药者治疗后HtSDS下降显著(P<0.05),而青春期开始后服药者HtSDS变化不明显(P>0.05)。多因素分析显示,服药初始年龄较小(偏回归系数为0.122,B=0.572,t=10.733,P<0.001)和服药时间较长(偏回归系数为−0.006,B=−0.211,t=−4.062,P<0.001)是伊马替尼抑制身高增长的独立影响因素。 结论 伊马替尼引起CML-CP儿童身高增长障碍,服药初始年龄越小、服药时间越长,伊马替尼对身高的影响越明显。

Abstract
Quantum dot (QD) has been extensively investigated as a nanoprobe to replace conventional organic dyes due to its unique optical properties. However, nanotoxicity of QD greatly hampers its biomedical applications, particularly in in vivo imaging. It is critical to functionalize QD and/or composite QD with other functional materials for biocompatibility, multifunction and expanded applications. In this review, advances of QD-based nanocomposites are addressed with emphasis of their synthesis, fundamental understanding and applications in biosensor, multimodal imaging, drug delivery, diagnostics and cancer therapy. Some specific QD-based bionanosystems and future development directions are also discussed.

Abstract
Refractory chronic GVHD (cGVHD) is an important complication after allogeneic hematopoietic SCT and is prognostic of poor outcome. MSCs are involved in tissue repair and modulating immune responses in vitro and in vivo. From April 2005 to October 2008, 19 patients with refractory cGVHD were treated with MSCs derived from the BM of volunteers. The median dose of MSCs was 0.6 × 10(6) cells per kg body weight. Fourteen of 19 patients (73.7%) responded well to MSCs, achieving a CR (n=4) or a PR (n=10). The immunosuppressive agent could be tapered to less than 50% of the starting dose in 5 of 14 surviving patients, and five patients could discontinue immunosuppressive agents. The median duration between MSC administration and immunosuppressive therapy discontinuation was 324 days (range, 200-550 days). No patients experienced adverse events during or immediately after MSC infusion. The 2-year survival rate was 77.7% in this study. Clinical improvement was accompanied by the increasing ratio of CD5+CD19+/CD5-CD19+ B cells and CD8+CD28-/CD8+CD28+ T cells. In conclusion, transfusion of MSCs expanded in vitro, irrespective of the donor, might be a safe and effective salvage therapy for patients with steroid-resistant, cGVHD.

Abstract
At present Helicobacter pylori (HP) was taken to be closely related to chronic atrophic gastritis and peptic ulcer. 226 patients with symptoms of upper digestive tract by endoscope were examined and chronic atrophic gastritis and peptic ulcer were diagnosed. Mucous membrane from gastric antrum was taken and cultured, and found that 136 cases of 226 patients were HP positive and the rate of positiveness was 60.18%. 200 kinds of Chinese herbal medicine were selected to investigate its inhibitory action on HP. Results indicated that 38 among 200 kinds of Chinese herbal medicine had inhibitory effects on HP, which provided evidence for diagnosis and treatment of chronic atrophic gastritis and peptic ulcer, also for inhibition of HP growth.

Abstract
Two models of pulmonary hypertension in rats have been made with either monocrotaline or passive smoking (with or without infection). The decrease of RBC acetylcholinesterase activity and the increase of acetylcholine content in blood were detected in both rat models, but did not in rats which were only once infected by E. Coli, and the pulmonary pressure of the latter did not raise either. Comparing 30 cases of acute attack period of chronic pulmonary heart disease with 30 cases of normal persons, RBC acetylcholinesterase decreased significantly, indicating that hyperfunction of cholinergic nerve existed in pulmonary hypertension and pulmonary heart disease.

Abstract
Moxibustion can accelerate the relief of arthralgia of rats suffering from adjuvant arthritis. At the same time, it promotes the recovery of SP in the sciatic nerve, and maintains SP and leu-enkephalin at a higher level in the lumbar spinal cord. The results show that the therapeutic effect of moxibustion in treating arthralgia bears some relation to activating the spinal enkephalin system and modulating the function of primary afferent neurons.
