Objective To explore whether IL-27 inhibited the pulmonary fibrosis through regulating the expression of TGF-β/Smad signaling pathway in the bleomycin-induced pulmonary fibrosis model. Methods Forty male C57/BL6 mice were randomly divided into normal control group(group A),bleomycin-induced pulmonary fibrosis group(group B),bleomycin+IL-27 group(group C)and bleomycin+IL-27 antibody group(group D) with 10 in each. Five mice in each group were sacrificed on days 7 and 28 after with intratracheal bleomycin. TGF-βR1,Smad1 and Smad3 in right lung tissue were measured by Western Blot. Results 1. In the bleomycin-induced pulmonary fibrosis model,the expression of TGF-βR1 was higher on days 7 and 28,which was inhibited by IL-27. 2. The expressions of p-Smad1 and p-Smad3 were highest in group D on days 7 and 28, but were lower in group C on day 7 than those in group B. Conclusion Exogenous IL-27 might alleviate pulmonary fibrosis through inhibiting the related protein phosphorylation in TGF-β/Smad signaling pathway.

Hyperparathyroidism is a common endocrine disease that seriously affects human health, depending on its etiology, which can be divided into three types: primary, secondary and tertiary. In clinical practice, we found that some primary hyperparathyroidism may be secondary or tertiary hyperparathyroidism caused by insufficient calcium intake and/or vitamin D deficiency/insufficiency, and become a common type of hyperparathyroidism. The daily calcium intake of Chinese people is generally insufficient. Vitamin D can promote the absorption of calcium, but vitamin D deficiency/insufficiency is also a worldwide public health problem. Long-term hypocalcemia will stimulate parathyroid hyperplasia and secrete excessive parathyroid hormone, resulting in parathyroid hyperfunction (pre-hyperparathyroidism) and then secondary hyperparathyroidism, both of which may damage bone and release calcium into blood, leading to diseases of multiple organs and tissues. The detection of bone metabolism indexes such as calcium, magnesium, phosphorus, parathyroid hormone and vitamin D may be helpful for the early diagnosis of pre-hyperparathyroidism and hyperparathyroidism. Supplementation of calcium and vitamin D in early stage can control the development of the disease and change "unpreventable and uncontrollable" into "preventable and controllable" . The health screening of bone metabolism indexes and parathyroid ultrasonography should be advocated, and the prevention and treatment of calcium and/or vitamin D insufficiency associated parathyroid hyperfunction and hyperparathyroidism should be strengthened, so as to greatly improve the bone health, urinary calculus, metastatic vascular calcification and systemic abnormal calcium migration and precipitation in the population.

Differentiated thyroid cancer is one of the most common endocrine malignant tumors, and thyroidectomy is its basic treatment measures. Insufficient attention is paid to its postoperative bone hungry syndrome and parathyroid hyperfunction or hyperparathyroidism, which will seriously affect the patient’s life quality and prognosis. This paper will explore the etiology, dangers, diagnosis, prevention, and treatment for hungry bone syndrome, parathyroid hyperfunction and hyperparathyroidism of thyroid cancer patients after thyroidectomy.

Metastatic vascular calcification and calcinosis universalis, as severe complications of parathyroid hyperfunction and hyperparathyroidism, have attracted more attention in patients with renal secondary hyperparathyroidism and primary hyperparathyroidism. But, they are of little concern in patients with long-term negative calcium balance related parathyroid hyperfunction or hyperparathyroidism caused by calcium and/or vitamin D insufficiency (CVI). CVI is common in the population. Relatively low level of serum calcium and negative calcium balance caused by long-term CVI result in parathyroid hyperfunction or hyperparathyroidism, which may cause secretion of PTH beyond the physiological level, leading to bone absorption and release of a large amount of bone calcium into the blood. It may not only cause bone loss and osteoporosis, but also form metastatic vascular calcification or calcinosis universalis presented by cardiovascular diseases and other multi-organ lesions. Early calcium deposition can gradually fade after reasonable treatment, but middle arterial calcification is not easy to fade once it occurs. Therefore, vascular calcification and calcium deposition should be actively prevented and early screened and diagnosed. The early prevention, diagnosis and treatment of parathyroid hyperfunction or hyperparathyroidism can prevent, delay, or even reverse the occurrence and development of metastatic vascular calcification and calcinosis universalis, which is significant for disease prevention and protecting the patients' health influenced by these diseases.

Objective:To explore the risk factors of lymph node metastasis (LNM) in early gastric cancer (ECG), and establish a risk-prediction model based on LNM.Method:Four hundred and twenty-seven EGC patients undergoing curative radical gastrectomy were enrolled in this study. The risk factors for LNM of ECG were analyzed with Logistic regression. LNM risk was stratified and risk-predicting model was established. The risk-predicting model was measured by area under ROC curve. According to the same standard, clinical data of 133 patients with EGC who underwent radical surgery were selected for external verification of the model.Results:The frequency of LNM was 13.3% (32/427) in EGC patients. The LNM ratio of intramucosal carcinoma and submucosal carcinoma was 1.3% (3/237), 15.3% (29/190) respectively. Ulcer presence, tumor size >2 cm, undifferentiated tumor, submucosal invasion, neural invasion, and vascular tumor thrombus were significantly associated with LNM in EGC patients ( χ2=3.408, 16.379, 4.808, 29.804, 25.305, 47.120, respectively P<0.05). Multivariate analysis suggested that ulcer presence, tumor size >2 cm, depth of invasion, neural invasion, and vascular tumor thrombus were independent predictors of LNM in EGC patients, ( OR=0.326, 2.924, 11.824, 13.047, 7.756, respectively P<0.05). LNM predicting model is established, P=e^x/(1+e^x),x=-4.792-1.122 ulcer presence+1.073 tumor size+2.470 depth of invasion+2.569 neural invasion+2.048 vascular tumor thrombus,ROC-AUC of risk-predicting model was 0.845, the best cut-off was 0.094, the sensitivity was 72.70%, the specificity was 77.20%. The external verification result revealed the AUC of ROC was 0.840. The four-grid table is constructed by predicting model results and the postoperative pathological examination. The sensitivity and specificity of the model are calculated to be 82.35% and 68.96%, respectively. Conclusions:EGC patients with ulcer presence, tumor size >2 cm, depth of invasion, vascular tumor thrombus, and neural invasion have higher risk of LNM, the risk-predicting model can identify the high probability of LNM .

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 investigate the expression of KLF11 in gastric cancer tissues and cell lines as well as its effect on proliferation and apoptosis of human gastric cancer cells BGC823.Methods:Sixty pairs gastric cancer tissues and corresponding adjacent tissues were collected. The expression of KLF11 mRNA in gastric cancer tissues and their adjacent tissues was detected by RT-PCR. The expression of KLF11 was detected in gastric cancer cells. KLF11 expression was silenced. The proliferation of cells were detected by using MTT assay. Flow cytometry was used to detect the cell cycle and cell apoptosis rate. Western bloting was used to examine the changes of concentration of proteins associated with cell cycle,cell apoptosis and Wnt/β-catenin signaling pathway related proteins. The activity of Caspase3 enzyme was detected by spectrophotometry.Results:The relative expression of KLF11 mRNA in gastric carcinoma tissues was significantly higher than that of the adjacent tissues ( t=11.38, P<0.05). Its expression was related to tumor size, depth of invasion, lymph node metastasis and TNM clinical stage (all P<0.05). The proliferation of BGC823 cells was significantly suppressed after KLF11 silencing ( F=19.56, P<0.05), and the cell cycle was arrested in G 0/G 1 phase [(41.40%±0.98%) vs. (66.53%±1.01%), F=32.69, P<0.05]. Meanwhile, the apoptosis rate was significantly increased by KFL11 silencing [(41.44%±1.59%) vs. (15.42%±0.86%), F=35.35, P<0.05]. The results of Western blotting revealed that the expression of Bax and Cleaved Caspase3 was significantly increased ( F=23.33, 33.63; both P<0.05), wheras that of β-catenin, Bcl-2, CyclinD1and CyclinE was significantly reduced ( F=22.21, 16.24, 26.75, 33.42; all P<0.05). The activity of Caspase3 enzyme was enhanced ( F=16.56, P<0.05). Conclusion:KLF11 was highly-expressed in gastric cancer tissues and cells, KFL11 silencing could inhibit gastric cancer cells proliferation and induce cell apoptosis via Wnt/β-catenin signaling pathway.
