Objective Oral lichen planus ( OLP) is a common complaint in the oral mucosa , for which there is no definite therapy hitherto.This article aimed to investigate the possible effect of Huashi Xingyu Qingre Decoction (HXQD) on OLP. Methods This study included 30 randomly selected cases of OLP treated with HXQD .Fasting venous blood and total serum protein were obtained before and after medication for screening and identification of OLP-related differential proteins by two-dimensional fluorescence differ-ence gel electrophoresis (2D DIGE) and liquid chromatography-mass spectrometry (LC-MS), followed by Western blot validation . Results Haptoglobin , antithrombin Ⅲ, C1 complement , and vitamin D binding protein were differentially expressed in the serum of the OLP patients before and after treated with HXQD .Compared with the baseline , the expression of haptoglobin was significantly in-creased (103.086 ±27.536 vs 159.704 ±24.228, P<0.05) while that of antithrombin Ⅲ remarkably decreased after treatment (150.00 ±54.04 vs 98.00 ±28.04, P<0.05). Conclusion Haptoglobin, antithrombin Ⅲ, C1 complement, and vitamin D binding protein are differentially expressed in the serum of OLP patients before and after HXQD medication , which may be associated with the development and progression of OLP .

OBJECTIVE To evaluate the clinical application of flow-through hybridization to human papillomavirus(HPV) subtype detection.METHODS A total of 305 female patients infected with HPV were selected for HPV subtype analysis using flow-through hybridization and the assessment of HPV subtype on cervical lesions was analyzed.RESULTS All 21 different subtypes were found.From 305 cases 173 patients were infected with single-type HPV and 132 patients were infected with multiple-type HPV.The most commonly found high-risk types were HPV16(17.6%),HPV52(9.8%),HPV58(9.0%),HPV33(6.3%),HPV18(5.4%) and HPV68(5.2%) and the low-risk types were HPV11(14.3%) and HPV6(6.5%).The high-risk HPV increased and the low-risk HPV declined along with the upgrade of the cervical lesions.CONCLUSIONS Technology of flow-through hybridization is able to detect multiple HPV subtype.The distinction between low and high-risk HPV subtypes is seemed useful in prevention and management of cervical cancer.

Objective To analyze the effect of Huashi Xingyu Qingre decoction therapy through identification of the differentially expressed saliva proteins of oral lichen planus. Method The saliva of OLP patients before and after treatment were collected. Total saliva proteins were extracted. The differentially expressed saliva proteins were screened by two-dimensional fluorescence difference gel electrophoresis and identified by liquid chromatography-mass spectrometry. The differentially expressed proteins were analyzed by Western-blot. Results Six differentially expressed proteins were identified as salivary amylase, serum albumin, IgM, carbonic anhydrase VI, zinc-α2- glycoprote and sIgA. The expression level of serum albumin, IgM, carbonic anhydrase VI and zinc-α2-glycoprotein after treatment were lower than that before. However, the expression level of sIgA was higher. The differences were statistically significant. Conclusions Some differentially expressed saliva proteins of OLP before and after Huashi Xingyu Qingre decoction therapy are characterized, and they may play a vital part in the occurrence and development of OLP.

Objective:To summarize and elucidate the impact of ambient air pollution on biological aging among middle-aged and older adults.Methods:"Air pollution""Biological age""Epigenetic age""Biological aging"and"Epigenetic aging", as well as specific names of air pollutants and biological age were used as search keywords. This study searched the databases of PubMed and Web of Science for eligible English articles and CNKI, CQVIP, Wanfang, CBM, CSTP and other Chinese databases for eligible Chinese articles from inception until June 30, 2023. The language was limited to Chinese and English.Results:Among the 14 included articles, five studies investigated the impact of air pollution on DNA methylation age using different algorithms, while six studies explored the relationship between air pollutants and telomere length. Six studies focused on frailty as an outcome, and an additional study revealed the relationship between fine particulate matter (PM 2.5) and its components with composite indicator age (KDM age). The results indicated that, although different forms of biological ages were susceptible to different ambient air pollutants at different degrees, previous studies had consistently found that the increased levels of PM 2.5 and one of its major components, black carbon (BC), could significantly accelerate the biological aging of middle-aged and older adults. Similar trends were observed with nitrogen oxides (NO x) and ozone (O 3) but with relatively limited evidence. Conclusion:Major air pollutants could accelerate the biological aging of middle-aged and older adults.

Objective To investigate midwives human resource and accouched delivery mode, and analyze the midwives personnel structure and manning level status, so as to provide reference for the construction and reasonable allocation of midwifery team. Methods Self-designed scale was used to comprehend accouched delivery mode and midwives human resource status in 20 hospitals which owned obstetric room and were selected by convenient sampling method form May to June 2014 in Beijing, and the results of scale were analyzed and compared. Results The characteristics of midwifery team were almost aged from 25 to 34 (59. 5%), and highest education levels were associated degree (50. 2%) and bachelor degree (41. 7%), and non professional midwifery graduation was 62. 6%, and primary occupational title accounting for 69. 8%. The accompanied delivery rate in 20 hospitals was 90. 0%, 72. 2% of labor was whole process companion, and 27. 8% people chose to accompany at first or second labor stage. 45% one shift of midwives lasted 12 to 16 h, and just 25% of them was 8 h working length for one shift, and 20% of them worked lasted 24 h, and 10% of midwives had uncertain length work shift. Different accouched delivery mode had similar midwifery allocation, and one delivery bed averagely disposed ( 3. 75 ± 1. 21 ) midwives, and one midwife should take responsibility for (137. 92 ± 73. 09) neonatus in one year. Conclusions The educational level and occupational title of midwives require to improve in Beijing region, the midwives proportioning should research and allocate combined with accouched delivery mode and woke load. Nursing management and training tutor should actively explore and regulate midwives continuing education and training system bonded with national situation.

Chronic visceral hypersensitivity is an important type of chronic pain with unknown etiology and pathophysiology. Recent studies have shown that epigenetic regulation plays an important role in the development of chronic pain conditions. However, the role of miRNA-325-5p in chronic visceral pain remains unknown. The present study was designed to determine the roles and mechanism of miRNA-325-5p in a rat model of chronic visceral pain. This model was induced by neonatal colonic inflammation (NCI). In adulthood, NCI led to a significant reduction in the expression of miRNA-325-5p in colon-related dorsal root ganglia (DRGs), starting to decrease at the age of 4 weeks and being maintained to 8 weeks. Intrathecal administration of miRNA-325-5p agomir significantly enhanced the colorectal distention (CRD) threshold in a time-dependent manner. NCI also markedly increased the expression of CCL2 (C-C motif chemokine ligand 2) in colon-related DRGs at the mRNA and protein levels relative to age-matched control rats. The expression of CXCL12, IL33, SFRS7, and LGI1 was not significantly altered in NCI rats. CCL2 was co-expressed in NeuN-positive DRG neurons but not in glutamine synthetase-positive glial cells. Furthermore, CCL2 was mainly expressed in isolectin B4-binding- and calcitonin gene-related peptide-positive DRG neurons but in few NF-200-positive cells. More importantly, CCL2 was expressed in miR-325-5p-positive DRG neurons. Intrathecal injection of miRNA-325-5p agomir remarkably reduced the upregulation of CCL2 in NCI rats. Administration of Bindarit, an inhibitor of CCL2, markedly raised the CRD threshold in NCI rats in a dose- and time-dependent manner. These data suggest that NCI suppresses miRNA-325-5p expression and enhances CCL2 expression, thus contributing to visceral hypersensitivity in adult rats.
