AIM: To explore the feasibility of combining small pieces of allo-conjunctiva transplantation (ACT) with amniotic membrane transplantation (AMT) to reconstruct ocular surface.METHODS: Bilateral superior bulbar conjunctiva of New Zealand white rabbits were burned by NaOH (1mol/L).After 24h, the right eye (experimental groups Exps) was performed AMT and ACT;the left eye (control groups Cons)was done merely ACT. The viability and function of allografts were identified by PAS staining and scanning electron microscope (SEM) of cytology impression (CI) every week after the operation.RESULTS: In Exps, no obvious rejection was observed.All grafts survived, extended and covered the conjunctival defect. The appearance of grafts, and the shape, number,and function of goblet cells recovered perfectly four weeks after the operation;however, in Cons, obvious rejection was found. Seven grafts were rejected and. symblepharon was observed in those eyes. The appearance of survival allografts were similar to the normal conjunctiva, with similar shape, number and function of goblet cells till the fifth week after the operation. The survival ratet was significantly higher in Exps than in Cons (P ＜0.05).CONCLUSION: ACT based on AMT can be considered a good way to reconstruct ocular surface for large area conjunctiva alkali burns in early-stage.

Wound healing is achieved through four coordinated and overlapping phases, 1) haemostasis, 2) inflammatory, 3) proliferative and 4) remodelling. This complex process can be disrupted by local or systemic risk factors, resulting in delayed healing and progression to a chronic wound. Chronic wounds interact closely with a patient’s comorbid illnesses, social circumstances and functional status. The Family Physician plays an important role to optimise patient and wound risk factors that impair wound healing. Strategies to enhance wound healing include optimising local wound care based on TIME principles, identification and optimising the underlying causes for poor wound healing and education to the patients and their caregivers in wound care, dressing changes and avoidance of risk factors to prevent recurrence. Complex chronic wound care may need a multi-disciplinary approach involving allied health members to provide additional nutritional, nursing and psychosocial support. There is a role for adjuvants such as hyperbaric oxygen therapy and platelet derived growth factor gels to enhance healing in certain wounds but stronger evidence is required to support its routine use.

Objective To analyze efficacy of rituximab combined with chemotherapy for 35 patients with aggressive B cell non-Hodgkin’s lymphoma.Methods 70 patients with aggressive B cell non-Hodgkin’s lymphoma were chosen from Hematology Department of First Affiliated Hospital of Liaoning Medical University and divided into observation group and control group at random, each group with 35 cases.The control group were treated with CHOP chemotherapy, and the observation group were treated with anti-CD20 monoclonal antibody rituximab combined with CHOP chemotherapy. The efficacy and toxicity of two group were compared.Results The total effective rate of observation group was significantly higher than that of control group (80.0%vs.37.1%;χ2 =13.246,P<0.001).Fever cases of observation group were significantly more than those of control group (15vs.4;χ2 =8.741,P=0.003), while the other adverse reactions of leucopenia and gastrointestinal reaction between two groups were not significantly different. Conclusion For patients with aggressive B cell non-Hodgkin’s lymphoma, rituximab combined with CHOP chemotherapy has better short-term effects and its adverse reactions are tolerable, which helps patients to improve the quality of life.

AIM : To observe the effect of stress and ovariectomy on behavior activity in mice and the prevention and therapy of the TCM complexⅠcomposed of spine date seed and common anemarrhena rhizome. METHODS : The effect of stress and ovariectomy were investigated on bedtime, survival time under hypoxia, climbing time on the string and number of times of the activity in mice, and the prevention and therapy of TCM the complexⅠwere observed. RESULTS : The effect of stress, ovariectomy, stress and ovariectomy were different on bedtime, survival time under hypoxia and climbing time on the string and the number of times of the activity in mice. The effect of stress and ovariectomy on previous parameters was stronger than that of stress or ovariectomy lonely in mice. The stress and ovariectomy resulted in sleep impairment, the decreasing of the survival time under hypoxia and climbing time on the string, and the increasing of the number of times of the activity in mice. CONCLUSION : The TCM complex I can alleviate the high sensitivity to the environment in mice with ovariectomy and stress, which is similar to the mechanism of human climacteric syndrome.

Objective To analyze the curative effects and complications of ventriculo-peritoneal shunt in treating hydrocephalus caused by different diseases in children. Methods The data of 289 children with hydrocephalus who were performed ventriculo-peritoneal shunt were examined and the incidence rate of complications was analyzed. Results Thirty-seven incidences of complications occurred in 24 patients with the total incidence rate of 12.46%.There was obstruction of proximate tube in five cases,distal end in two cases,with the obstruction rate of 2.42%.Postoperative infection happened in nine cases(3.11%).Bacterial culture was positive in three cases,two of which were Staphylococcus epidermidis and Bacillus coli in the other one.Negative results were found in six patients for the bacterial culture.Subdural hematoma occured in one case,and tube break after injury in two cases.Slit ventricle syndrome broke out seven times in three cases,leakage of cerebrospinal fluid in two,exposure of pumps in three,and subcutaneous hydrops in two.Four cases(1.38%)were dead from infection. Conclusion Ventriculo-peritoneal shunt is preferred for hydrocephalus in children if the complications are well prevented and controlled.

Background and purpose:MicroRNA-486-5p (miR-486-5p) has been demonstrated to play an important role in many kinds of tumor, however, there are few reports about the relationship between miRNA-486-5p in gastric carcinoma. This study was aimed to explore the effect of miR-486-5p on the proliferation, apoptosis and migration abilities of the human gastric cancer cell line SGC7901.Methods:Quantitative real-time PCR (qRT-PCR) analysis was performed to detect the expression of miR-486-5p in the SGC7901 and GES-1 cells, miR-486-5p over-expressing plasmid was constructed and transfected into the human gastric carcinoma cell line SGC7901 using LipofectamineTM2000. The expression of miR-486-5p of the transfected cells was measured by qRT-PCR, the proliferation level of SGC7901 cells was detected by MTT method, the apoptosis rate of the cells was measured by lfow cytometry and the in vitro migration abilities of SGC7901 cells by transwell test. Results:The miR-486-5p expression in SGC7901 cells was down-regulated compared with GES-1 cells. The expression of miR-486-5p in SGC7901 cells that was transfected miR-486-5p over-expressing plasmid was obviously up-regulated. The proliferation and migration abilities of SGC7901 cells were inhibited signiifcantly, and the apoptosis rate of the cells increased. Conclusion:miR-486-5p can effectively suppress the proliferation and in vitro migration abilities of SGC7901 cells, indicating that miR-486-5p might be used as a target for molecular therapy of gastric cancer.

Drug combination is extensive in the clinical real world,which is an important part and the inherent requirements of the post-marketing evaluation of traditional Chinese medicine (TCM). The key issues and technology include multi-domain and multi-disciplinary such as the rationality, efficacy and safety evaluation of combination drug starting from clinical real world, study on component in vivo and mechanism of combination drug, the risk/benefit assessment and cost-benefit evaluation of combination drug and so on. The topic has been studied as clinical demonstration on combination therapy of variety of diseases such as coronary heart disease, stroke, insomnia, depression, hepatitis, herpes zoster, psoriasis and ectopic pregnancy.
