Objective To analyze clinical features of papillary thyroid microcarcinoma(PTMC) and to evaluate the diagnosis and treatment for PTMC.Methods The clinical data of 447 cases of PTMC receiving surgical treatment and confirmed by pathology were reviewed.Color Doppler ultrasonography was used to identify thyroid nodules and cervical lymph nodes,and frozen section was used to confirm the pathological diagnosis during operation.104 cases received unilateral lobectomy,22 cases received unilateral lobectomy plus isthmectomy,321 cases received total thyroidectomy,257 cases underwent central neck dissection,and 54 cases underwent lateral neck dissection(level Ⅵ included).All cases took levothyroxine to maintain low TSH level after operation,and were followed up through telephone or in out-patient clinic.Results Central compartment node metastasis was found in 144 patients,and lateral neck metastasis was found in 41 cN1 cases.The age,extra-capsular invasion and multifocal carcinoma were independent risk factors of PTMC.The number of positive nodes in level Ⅵ was positively correlated with the risk of lateral node metastasis.395 cases were followed-up successfully for 20 to 42 months,with the media follow-up of 32 months.During the follow-up,recurrence or metastasis was found in 15 cases,and no death happened.Conclusions PTMC has no specific symptoms,and was difficult to be diagnosed before operation.Physical examination and color Doppler ultrasonography should be used as routine examination.Thyroid lobectomy and total thyroidectomy plus central node dissection should be major surgical treatment for PTMC patients.Lateral neck dissection should be considered in all cN1 patients.

Eight-year program education is the heated topic in the field of medical education across the country.The system of eight-year program education can be discussed as a system,from the view of system philosophy.We analyzed beth internal relationships and external relationships connected to the system,so as to look upon the eight-year program education in its entirety.And then we discussed about the problems of epistemology and methodology on that basis.

ObjectiveIn order to understand changes of immunological response under different psychic state. MethodsMice were divided into two groups,male and female group, 1: 2, were feeded together for together group, anther was that mice, male, were feeded solely for thesolely group. Male mice in two groups were immunized with sheep red blood cell(SRBC). Titer of antiboty against SRBC and IL -2 in serum wasdetected. Results The titer of antibody against SRBC in together group was higher than that in solely group. The concentration of IL - 2 was lowerin the solely group comparing with the together group. ConclusionIt was suggested that psyxhological status had impact on immune system.

It is inevitable for colleges and universities to reform their information literacy education course with the coming of education informationization time.The construction elements of MOOC-based flipped classroom for information literacy education course in colleges and universities were studied in aspects of teaching design, classroom activities, hardware, teachers literacy based on the analysis of its necessity and feasibility, and strategies were put forward for colleges and universities to construct their multi-mainstay plus multi-element flipped classroom for information literacy education course.

Objective To evaluate the clinical value between peritoneal lavage cytology (PLC) and prognosis of gastric cancer. Methods The peritoneal lavage fluid of 60 gastric cancer patients and 12 noncancer patients were collected,different methods were used to examine the exfoliated cancer cells,and relationships between positive results and relative clinico-pathological parameters were evaluated.Results The positive rate of PLC was 31.8%,and was positively correlated with the degree of histologic differentiation of gastric cancer (P0.05). The postoperative one-year recurrence and survival rates of the positive and negative groups were significantly different(P

With the increase of the incidence and the refinement of clinical treatment,the clear preoperative staging and the assessment of tumor recurrence and metastasis of cervical cancer is particular important.Different results may be explained in the same tumor applied different methods of imaging examination,which influences the clinical diagnosis and treatment.So imaging examination plays a more and more important role in the assessment of preoperative staging and tumor recurrence.

OBJECTIVETo study the relationship between Chinese medical syndrome types and metabolomics of non-small cell lung cancer (NSCLC) patients.

METHODSTotally 120 NSCLC patients were assigned to asthenia syndrome group and sthenia syndrome group, 60 in each group. Meanwhile, 60 cases of benign pulmonary nodules in physical examinations were recruited as the control group. Tumor tissues or benign pulmonary nodules tissues were obtained by thoracoscope. Changes of their metabolites were observed using gas chromatography-mass spectrometry (GC-MS). Their differences were studied using principal component analysis (PCA) and partial least-squares discriminant analysis (PLS-DA). ROC curve analysis was performed in different metabolic compounds of sthenia and asthenia syndromes groups. The area under the curve (AUC) was calculated to evaluate the sensitivity of diagnosing syndrome types.

RESULTSCompared with the control group, difference existed in 16 compounds. Of them , contents of citric acid, pyruvic acid, alanine, choline phosphate, glycerol phosphate choline, linoleic acid, oleic acid, lactic acid, inositol were more in the two tumors group than in the control group. Difference existed in 10 compounds between the sthenia syndrome group and the asthenia syndrome group. Of them, citric acid, pyruvic acid, alanine, choline phosphate, glycerol phosphate choline, lactic acid, and inositol were more in the asthenia syndrome group than in the sthenia syndrome group. Contents of valine, glucose, and glutamine were more in the sthenia syndrome group than in the asthenia syndrome group. ROC curve analyses of different compounds indicated that AUC of lactic acid and glucose was more than 0.8 (P < 0.01); AUC of inositol, choline phosphate, and glycerol phosphate choline was more than 0.7 (P < 0.01); AUC of valine, citric acid, glutamine, alanine, and pyruvic acid was more than 0.6 (P < 0.05).

CONCLUSIONSThere existed certain correlation between CM syndrome types and metabolomics of lung cancer. Lactic acid, glucose, inositol, choline phosphate, glycerol phosphate choline, valine, citric acid, glutamine, alanine, pyruvic acid were sensitive diagnostic compounds, and the first four kinds were most sensitive compounds.

Objective To observe the effects of polysaccharide extracted from Yangwei Mixture on immunologic functions in mice.Method Immuno-suppressant mice model was established by intraperitoneal injection of CTX.The effects of the polysaccharide were observed through phagocytosis test of mice celiac macrophagocyte and serum hemolysin level test as well as lymphocyte transformation test.Result The polysaccharide can obviously increase the percentage of phagocytosis of mice celiac macrophagocyte,accelerate the formation of hemolysin and promote the lymphocyte transformation.Conclusion Polysaccharide extracted from Yangwei Mixture is a good immuno-stimulant,and can counteract the immuno-suppression induced by CTX.
