Objective To investigate the correlation between ADAM33 T1, S2 gene polymorphism and Bronchial asthma risk in china. Methods We retrived the relevant published studies about ADAM33 T1, S2 gene polymorphism and bronchial asthma risk. Then we divided the population into Chinese and other Asian population. Odds ratio (OR) of Case group and control group was selected as the effect index. Stata 11.0 software was used to calculate heterogeneity test, ORs and 95%CI of two areas, and gave the forest plot and funnel plot of meta results. Results A total of 27 studies were included in this analysis,18 studies in ADAM33 T1 site were 3881 cases in case group, and 3780 cases in control group;and 14 studies in ADAM33 S2 site were 3222 cases in case group, and 3513 cases in control group. Additive model, dominant model, recessive model of ADAM33 T1 in Chinese had association with the susceptibility of bronchial asthma. The results were OR=1.488, 95% CI:1.002-2.167 in Additive model, OR=1.619, 95%CI:1.059-2.475 in dominant model;OR=2.523, 95%CI:1.910-3.333 in recessive model. Three models of ADAM33 T1 in other Asian country had no association with the susceptibility of Bronchial Asthma. Three gene model of ADAM33 S2 in Asian had no association with bronchial asthma susceptibility. Except ADAM33 T1 polymorphism in recessive model, other mode of T1, S2 had no publication bias in Chinese population. Conclusion There are association between ADAM33 T1 gene polymorphism and bronchial asthma, but ADAM33 S2 gene polymorphism and bronchial asthma have no association in Chinese population.

OBJECTIVETo investigate the effects of interleukin-17 (IL-17) on the proliferation, transformation and collagen synthesis of the lung fibroblasts in mice with bleomycin-induced pulmonary fibrosis.

METHODSIn a mouse model of pulmonary fibrosis established by intratracheal administration of 5 mg/kg bleomycin, the dynamic expressions of IL-17/IL-17 receptor (IL-17R) mRNAs were detected by RT-PCR. At 14 days following bleomycin administration, the pulmonary fibroblasts were isolated, cultured and identified. MTT assay was used to assess the proliferation of the pulmonary fibroblasts in response to IL-17 treatment at different concentrations, and RT-PCR and Western blotting were employed to examine the mRNA and protein expressions of α-smooth muscle actin (α-SMA) and types I and III collagen.

RESULTSIL-17/IL-17R mRNA levels were increased obviously in the pulmonary fibroblasts of rats with pulmonary fibrosis, and the highest expressions occurred at 14 days following bleomycin administration. Exogenous IL-17, at the optimal concentration of 50 ng/ml, significantly promoted the proliferation of the pulmonary fibroblasts in primary culture and obviously increased α-SMA expression and types I and III collagen synthesis in the fibroblasts.

CONCLUSIONIL-17 can promote the proliferation, transformation, and collagen synthesis of the pulmonary fibroblasts from rats with bleomycin-induced pulmonary fibrosis.

Objective: To establish a method for repairing extremities with extensively deep burn using large piece of fresh allogeneic scalp spliced by Meek glue combined with autologous microskin and observe its effect. Methods: Medical records of two male patients with extremely extensive deep burn admitted to our hospital from May to November in 2018 were retrospectively analyzed. Two patients aged 44 and 25 years respectively, with total burn area of 90% and 97% total body surface area (TBSA) and full-thickness burn area of 85% and 70% TBSA, respectively. Preoperatively, the surgical area on the extremities was calculated to estimate the necessary amount of allogeneic scalp and Meek miniature skin. The large piece of fresh allogeneic scalp spliced by Meek glue combined with autologous microskin was prepared according to the methods described as follows. Thin medium-thickness fresh scalps with 3% TBSA and 0.30-0.35 mm in depth were harvested from each donor and spliced into a large piece with epidermis upward by spraying Meek glue. Then the spliced scalp was punched after covered with a single-layer gauze. Autologous microskin was transported onto the dermis of fresh large piece of allogeneic scalp by traditional floating method. Bilateral extremities with full-thickness burn of two patients were selected for self-control. The left upper extremity was denoted as treatment group while the right upper extremity was denoted as control group in Patient 1. The right lower extremity was denoted as treatment group while the left lower extremity was denoted as control group in Patient 2. Wounds in the treatment group were treated with fresh large piece of allogeneic scalp spliced by Meek glue and autologous microskin with expansion ratio of 1∶15 after escharectomy, while wounds in control group received grafting of Meek miniature skin with expansion ratio of 1∶6 and or 1∶9 after escharectomy. The donors of allogeneic scalp were 32 males who were the relatives or friends of the patients, aged 21-50 years, with scalp area of (548±48) cm². The healing conditions of donor sites of scalp were observed on post operation day 10, and were followed up within 3 months after operation to observe whether forming alopecia and hypertrophic scar or not. Wound healing condition was evaluated during follow-up in post operation week (POW) 2-5 and 4 months after operation. Wound coverage rates were calculated in both treatment and control groups in POW 2, 3, 4, and 5. Results: The donor sites of all allogeneic scalp of donors healed completely on post operation day 10. There was no alopecia or hypertrophic scar within 3 months after operation for follow-up. In POW 2, allogeneic scalp grafts basically survived in treatment group without obvious exudation, and most of the Meek miniature skin survived in control group with obvious exudation. Part of allogeneic scalp grafts dissolved and detached in treatment group in POW 3, and the surviving grafts scabbed. The eschar detached and new epithelium was observed in treatment group in POW 4 and 5. In POW 3-5, surviving Meek miniature skin in control group creeped and was incorporated, and the wounds shrank. Hypertrophic scar was observed in both treatment and control groups 4 months after operation, without obvious difference in scar as a whole. The wound coverage rates were respectively 84%-98% and 76%-92% in treatment group of two patients in POW 2-5, close to or higher than those of control group (35%-97% and 28%-81%, respectively). Conclusions The study establishes a novel method for splicing fresh allogeneic scalps into a large piece as the covering of microskin, which has good effect for repairing extensively deep burn wounds. Considering that allogeneic skin is scarce, this method may be a new option in clinical treatment for extensively deep burn patients.

【Objective】 To analyze the clinicopathological features of bladder urothelial carcinoma BUC in children and to share the experience of diagnosis and treatment. 【Methods】 The clinicopathological data, diagnosis and treatment process of a rare 9-year-old boy with BUC treated in the Second People’s Hospital of Kashgar were reported and the literature was reviewed. 【Results】 The main clinical symptom is hematuria. Both preoperative urinary ultrasound and CT urography (CTU) identified the tumor, which was then removed with transurethral holmium laser resection under general anesthesia. Postoperative pathology confirmed papillary urothelial neoplasm of low malignant potential (PUNLMP). Epirubicin hydrochloride instillation was administered, and no evidence of recurrence or progress was detected during the 3-month follow-up. 【Conclusion】 Bladder urothelial carcinoma in children is extremely rare.The most common symptom is hematuria, and there are no characteristic signs. Urinary ultrasound is the first choice for preoperative imaging, and transurethral resection of the carcinoma results in good recovery.There is no recommendable instillation, and patients need long-term postoperative follow-up.

OBJECTIVEThe purpose of this study was to investigate the effect and mechanism of Vav3 gene on the proliferation of human gastric cancer cell line SGC7901.

METHODSThe expressions of Vav3 proten in gastric cancer tissue, tumor-adjacent tissue, human gastric cancer cell line SGC7901 and gastric epithelial cell line GES-1 cells were tested by Western blot. Vav3-siRNA was transfected into the SGC7901 cells. The proliferation of SGC7901 cells in vitro was measured by MTT assay. Cell cycle of SGC7901 cells was determined by flow cytometry.The expressions of proliferation-related genes PCNA, p16, cyclin D1, Rb were determined by qPCR and Western blot assay. Orthotopic transplantation nude mouse models of gastric cancer were prepared, and the tumor growth and expressions of PCNA, P16, cyclin D1, and Rb proteins were examined.

RESULTSThe relative expressions of Vav3 in the gastric cancer and peritumoral tissue were 0.910±0.242 and 0.243±0.045, respectively; the relative expressions of Vav3 in SGC7901 and GSE-1 cells were 0.925±0.127 and 0.277±0.038, respevtively (both P<0.05). The expression of Vav3 protein in SGC7901 cells was effectively inhibited by Vav3-siRNA. Proliferation of SGC7901 cells was inhibited by (83.43±10.17)% after 80 nmol/L Vav3-siRNA transfection (P<0.05). The ratio of SGC7901 cells in G0/G1 phase was increased, and in S phase decreased after Vav3-siRNA transfection (both P<0.05). The expressions of PCNA and cyclin D1 were decreased in cells after Vav3-siRNA transfection, and expressions of p16 and Rb were increased after Vav3-siRNA transfection (P<0.05 for all). The tumor growth in the Vav3-siRNA group was much slower than that in the other 2 control groups of nude mouse models. Compared with the two control groups, expressions of PCNA and cyclin D1 were significantly lower in the Vav3-siRNA group, while expressions of p16 and Rb were increased (P<0.05 for all).

CONCLUSIONVav3 can promote the proliferation of gastric cancer cells by regulating proliferation-related genes.
