Objective Few studies are reported on the prevention and management of oral mucositis(OM) induced by post-operative radiotherapy in patients with oral cavity cancer.This study aimed to investigate the therateutic effect of the recombinant human epidermal growth factor(rhEGF) gel on radiation-induced OM. Methods Sixty-eight cases of radiation-induced OM after surgery for oral cavity cancer were randomly divided into an experimental and a control group of equal number,the former treated with rhEGF gel while the latter with borax mouthwash. Comparisons were made between the two groups of patients in the severity of oral cavity mucous membrane injury,the intensity of radiation-induced oral pain,the in-cidence of oral cavity infection, and the duration of radiotherapy. Results At 3 weeks of radiotherapy,the patients of the experimental group showed mainly mild and moderate OM while the controls chiefly moderate and severe OM,and at 6 weeks,the former exhibited mainly moderate while the latter chiefly severe OM, with statistically significant differences in the incidence rate between the two groups (P<0.01). The experimental group, compared with the controls, had a significantly higher incidence rate of grade-Ⅰ radiation-induced pain (47.1% vs 20.6%,P<0.01),but lower rates of grade-Ⅱ(17.6% vs 32.4%,P<0.01) and grade-Ⅲpain(2.9% vs 20.6%,P<0.01).The rates of oral infection and antibiotics medication were remarkably lower in the experimental group than in the controls(23.5% vs 38.2% and 11.8% vs 26.5%,P<0.05),and the duration of radiotherapy was markedly shorter in the former than in the latter ([42.37±3.14] d vs [48.47±4.39] d, P<0.05). Conclusion The rhEGF gel can significantly reduce the severity of radiation-induced oral mucositis,improve its symptoms,and shorten the time of postoperative radiotherapy for patients with oral cavity cancer.

AIM:To assess the changes in higher order aberrations after wavefront guided femtosecond laser assisted laser in situ keratomileusis ( FS-LASIK ) for moderate to high astigmatism.?METHODS: Eighty-eight eyes of 50 myopia patients with moderate to high astigmatism were included in this prospective study. There were 51 eyes with moderate astigmatism (≥-1. 50D and <-3. 00D) and 37 eyes with high astigmatism (≥-3. 00D). All patients underwent wavefront guided FS-LASIK. Uncorrected distance visual acuity ( UDVA ) , corrected distance visual acuity (CDVA), keratometry, central corneal thickness ( CCT)and higher order aberrations ( HOAs ) were evaluated before operation and 3mo postoperatively.?RESULTS:At the 3mo after operation, the mean UDVA of all eyes was above 20/20, better than before operation (P<0. 05), but CDVA remained unchanged (P=0. 36) and no eyes lost ≥2 lines of CDVA. Mean astigmstism of 85 eyes ( 97%) was reduced below - 1. 00D, mean astigmatism of 70 eyes ( 80%) was reduced below-0.50D(P<0. 05). The average corneal curvature was flatter by 3. 81 ± 1. 97D and CCT was reduced by 78. 66 ± 37. 22μm, postoperatively (P<0. 05). Coma and trefoil aberrations remained unchanged(P=0. 078, 0. 065). The spherical aberration, secondary astigmatism and the HOA root mean square ( RMS ) increased from 0. 19 ± 0. 06, 0.05±0. 02 and 0. 42±0. 12, preoperatively to 0. 32± 0. 17, 0. 26 ± 0. 08 and 0. 78 ± 0. 28 ( P < 0. 05 ), postoperatively.?CONCLUSION: Wavefront-guided FS-LASIK is a safe and effective option for the patients with moderate to high astigmstism although parts of HOAs increased.

Increasingly, researches have shown that long non-coding RNA (lncRNA) plays an important role in the oncogenesis and development of various tumors. Small nucleoli RNA host gene 3 (SNHG3) is a newly discovered lncRNA whose abnormally high expression is closely related to the overall survival and prognosis of tumor patients. SNHG3 can regulate the oncogenesis and development of tumors by endogenous competitive adsorption of miRNA, regulating cell cycle, mediating epithelial and mesenchymal transformation, and activating multiple signaling pathways. Therefore, in-depth research on the carcinogenesis mechanism of SNHG3 is helpful for early diagnosis, targeted therapy and prognostic assessment of relevant tumors. This paper reviews latest research progress on the expression and mechanism of SNHG3 in breast cancer, ovarian cancer, kidney cancer, liver cancer, stomach cancer, colon cancer, osteosarcoma and head and neck tumors to provide references for future studies.

Long non-coding RNA (lncRNA) is a group of non-coding RNA with length larger than 200 nucleotides. LncRNAs have limited or no protein-coding capacity due to lacking of open reading frame. Recent studies indicated that lncRNAs were involved in various cellular processes and their aberrant expression might lead to tumor development and progression. FOXD2 adjacent opposite strand RNA 1 (FOXD2-AS1) was found to exhibit aberrant expression in various malignancies, and its dysregulation level was closely related with prognosis of cancer patients. The biological functions and molecular regulatory mechanisms of FOXD2-AS1 in tumors will be summarized in this paper.

In recent years, with the change in life style, social environment, and national childbearing policy, the proportion of high-risk pregnant women has increased significantly, triggering the spectrum of obstetric diseases to constantly change, which has brought new challenges to the diagnosis and treatment of obstetrics. Traditional Chinese medicine (TCM) has been proved effective in dealing with a variety of obstetric diseases, and various treatment methods are available, which can serve as alternative means for solving refractory obstetric diseases. However, most obstetric clinicians are currently less aware of the therapeutic effects of TCM, which has significantly hindered its participation in clinical treatment. Therefore, the China Association of Chinese Medicine (CACM) organized the outstanding young obstetricians of TCM and western medicine to discuss 15 obstetric diseases responding specifically to TCM or integrated TCM and western medicine, including hyperemesis gravidarum, threatened abortion, ectopic gestation, cough during pregnancy, pregnancy-induced hypertension syndrome, maternal-fetal ABO incompatibility, postpartum hypogalactia, residual pregnancy tissue in uterine cavity, puerperal infection, pantalgia after childbirth, hematoma/undesirable healing after caesarean section, postpartum urinary retention, ileus after cesarean section, pelvic floor dysfunction, and postnatal depression. The suggestions for their treatment with TCM or integrated TCM and western medicine were also proposed, aiming to provide patients with effective and personalized treatments in clinical practice and improve the diagnosis and treatment effects of obstetric diseases, thus benefiting the public. At the same time, more obstetrical clinicians are expected to understand the therapeutic effects and advantages of TCM and draw on the strengths of both TCM and western, thereby promoting the establishment of an obstetric diagnosis and treatment system with Chinese characteristics.
