When directly breast feeding for preterm infants is not available,a preferred alternative is expressed maternal milk or donor breast milk.The evidences to date indicated that feeding preterm infants with expressed maternal milk and donor breast milk was associated with a slower growth in the early postnatal period,the effects on long-term growth in preterm infants was still unclear.Feeding with expressed maternal milk and donor breast milk could deliver preterm infants a degree of specific components of human milk.The potential benefits of the specific components for preterm infants were associated with promoting neurodevelopment and decreasing the incidence of feeding complications.Before expressed maternal milk and donor breast milk are widely used in clinical practice,further studies are still needed to explore the long-term effects on growth and development in preterm infants.

270 patients underwent single crown prosthodontics were randomly divided into 3 groups(n =90)and received gingival retraction with single-cord,double-cord and gingival retraction paste respectively.The prosthesis quality of the 3 groups was not statistically significant (P =3.209).The patient satisfaction was more and the gingival retraction time of the paste group was shorter than those of the cord groups(P<0.05).

Thyroid carcinoma is the most common endocrine maligancy, and the worldwide incidence has been rising in recent years. Differentiated thyroid carcinoma is the most common thyroid malignancy, which include thyroid papillary carcinoma and follicular thyroid carcinoma, accounting for about 90 percent of thyroid carcinoma incidence. Currently, surgical treatment, iodine radiotherapy and TSH suppressive therapy are the commonly accepted effective treatments for differentiated thyroid carcinoma, and most patients can be cured. But there are still some patients not sensitive to the general treatments, who have lost the treatment of opportunity. Molecular targeted therapy is an agonistic or suppressive treatment for molecular biology targets of malignant tumor, and currently is a frontier research in the field of malignancy treatment. By retrieving and analyzing the related literature of molecular targeted therapy of thyroid carcinoma through PUBMED in the past 5 years, the article introduced the current status of molecular targeted therapy of thyroid carcinoma.

Objective To study the immunoregulatory activity of eucommia ulmoides oliv polysaccharides (EOP) on immunodepressive mice. Method The immunodepressive mice model was established with cyclophosphamide (CY) treated. EOP was given with different doses, and mouse weight, thymus index, spleen index, abdominal cavity macrophage engulfing rates, engulfing index were measured. Result 300 grams Eucommia ulmoides Oliv crude drugs after withdraw separate gained 9.3 grams polysaccharides. After CY injection, the mouse weight, chest gland index, abdominal cavity macrophage swallowing rate, phagocytic count reduced. EOP could resist the mouse body weight drop induced by CY, elevate the thymus index of immunity low mouse, obviously increase mouse abdominal cavity macrophage engulfing rates and engulfing index (P

Objective: To study influencing factors for aspirin resistance in women with ischemic stroke.Methods: A total of 150 women with ischemic stroke, who visited to our hospital from Jun 2013 to Jun 2015, were selected.According to presence of aspirin resistance, they were divided into aspirin resistance group (n=61) and aspirin sensitive group (n=89).All patients received aspirin enteric-coated tablets on morning, then arachidonic acid pathway platelet aggregation inhibition rate and glycosylated hemoglobin A1c (HbA1c) level were measured in two groups on 10 h after administration.According to HbA1c level, patients were divided into normal blood glucose group (n=83) and elevated blood glucose group (n=67), then aspirin resistance rate was compared between two groups.Logistic regression analysis was used to analyze influencing factors for aspirin resistance.Results: Compared with aspirin sensitive group, there was significant rise in body weight[(63.5±7.9) kg vs.(66.9±10.2) kg]in aspirin resistance group, P=0.041.Compared with normal blood glucose group, there was very significant rise in aspirin resistance rate (14.46% vs.73.13%) in elevated blood glucose group, P=0.008.Multi-factor Logistic regression analysis indicated that body mass index (BMI) and blood glucose level were independent risk factors for aspirin resistance (OR=4.012, 3.012, P=0.016, 0.018).Conclusion: Incidence rate of aspirin resistance is high in women with ischemic stroke.Blood glucose control and body weight status may affect incidence of aspirin resistance.

The paper reviews the background and current situation of medical disputes and puts forward the concept of the reaction chain of medical disputes in view of their high occurrence rate and the difficulty in handling them. It discusses the framework, chief content, basic principles and major features of the reaction chain of medical disputes and argues that as a commonly used tool for handling medical disputes, the reaction chain renders it possible to check from the angje of the interests of the patients whether each party involved in the dispute has fulfilled its duties. Intended to improve the professional ethics of the physicians and the quality of medical care and calling on the patients to rebuild their confidence in the physicians, the reaction chain indicates that it is necessary to scientifically analyze the entire process and various influencing factors of medical disputes and bring into play the advantages of integration so as to successfully resolve medical disputes.

Objective To study the clinic value of digital three-dimensional shaping titanium mesh in repairing skull defects and reconstructing temporal muscle attachment points. Methods Eighty-two patients with skull defects from December 2013 to January 2016 were enrolled in this study. They were divided into two groups according to patients' will with 41 patients in each group. The patients in control group received traditional hand-shaping titanium mesh repair, the patients in observation group received individual digital forming technology to produce titanium mesh repair and reconstruct the temporal muscle attachment points at the titanium mesh temporal corresponding position. The rate of appearance satisfaction, operation time, the number of titanium nail and the rate of postsurgery adverse reaction was compared between the two groups. Results The rate of appearance satisfaction in observation group was significantly higher than that in control group: 97.56%(40/41) vs. 80.49%(33/41), P<0.05. The operation time and the number of titanium nail and in observation group was significantly lower than that in control group:(8.9 ± 1.6) h vs. (12.4 ± 2.4) h, (10.3 ± 0.9) pieces vs. (11.8 ± 1.8) pieces, P < 0.01. The rate of postsurgery adverse reaction in observation group was significantly lower than that in control group: 0 vs. 9.8%(4/41), χ2 = 4.21, P < 0.05. Conclusions The operation of repairing skull defects and reconstructing temporal muscle attachment points with digital three-dimensional shaping titanium mesh is simple. It can shorten the operation time, decrease the postsurgery adverse reaction, and increase the appearance satisfaction.

Objective To detect TCRγ gene rearrangements in skin lesions and peripheral blood of patients with parapsoriasis, and to study their clinical significance. Methods Totally, 20 patients with parapsoriasis were included in this study. BIOMED?2 multiplex PCR was performed to detect TCRγgene rearrangements in lesional skin (n=20)and peripheral blood(n=11)samples from the patients with parapsoriasis. Statistical analysis was performed to assess the relationship of TCRγ gene rearrangements with clinical types of parapsoriasis as well as general information and histopathological manifestations(including non?specific manifestations and atypical manifestations)of patients. Results TCRγ gene rearrangements were positive in lesional skin from 7 of the 20 patients, in peripheral blood from 3 of 11 patients, and in both lesional skin and peripheral blood from 2 patients. Positive TCRγ gene rearrangements in skin lesions were significantly correlated with mycosis fungoides(MF)?related atypical histopatho?logical manifestations(P<0.05), but those in neither skin lesions nor peripheral blood were correlated with gender and age of patients or clinical course and types of parapsoriasis(all P>0.05). During an average follow?up time of 44.85 ± 18.48 months, 1 case progressed into MF, and 2 were cured. Conclusions Positive TCRγgene rearrangements in skin lesions of patients with parapsoriasis may be correlated with MF?related atypical manifestations. The presence of TCRγgene rearrangements and atypical histopathological manifestations may suggest the possibility of progression from parapsoriasis into MF.
