Objective To discuss the pathological morphological features of the macrofollicular variant of papillary thyroid carcinoma ( MFPTC ) .Methods Clinical data of 2 cases of MFPTC were reviewed .The his-topathological and immunohistochemical features were analyzed .Relevant literatures were reviewed .Results The histological characters of MFPTC mainly included its multiple macrofolliculus , plenty of colloid and atypical nuclear morphology.Immunohistochemistry stain showed cytokeratin-19, Galectin-3 and HBME-1 expressed simultaneously. Conclusions MFPTC is a thyroid papillary carcinoma with unique histological characters .It should be differen-tially diagnosed from some benign lesions such as nodular goiter and follicular adenoma .Immunohistochemical stain of cytokeratin-19, Galection-3 and HBME-1 may be very helpful in the diagnosis and differential diagnosis .

OBJECTIVE To establish the quality control system of aseptic materials in sterilization and supply department. METHODS According to Antisepsis Technic Criterion,Criterion of Check and Accept of Sterilization and Supply Department in Hospital,and Criterion of Hospital Infection newly issued by National Ministry of Health,to provide quality control of aseptic meterials in hospital. RESULTS The aseptic materials of quality control were improved,and come to being systematic standardized. CONCLUSIONS The improved quality control is an important measure for the guarantee of quality control of aseptic materials.

OBJECTIVE To investigate the method of quality control on the whole process in sterilization supply department. METHODS According to issued by Ministry of Health all kinds of criteria and inspections,the whole process in sterilization supply department was analyzed,and then the quality was controlled. RESULTS The whole process of sterilization was standardized,systematized and programmed. CONCLUSIONS The quality control on the whole process is an effective measure to ensure the rate of supply eligibility and support.

Objective To investigate the effect of miR-30a on human osteosarcoma cell 143B in migration,invasion andcellviability.Methods 143BcellswereinfectedortransfectedwithrecombinantadenovirusmiR-30a(Ad-miR30a) and miR-30a inhibitor respectively .Wound healing assay was performed to detect the cell healing ability ( P<0.05 ) .Cell migration and invasion ability were determined by Transwell assay ( P<0.05 ) .The cell viability was analyzed by MTT assay ( P<0.01 ) .Real-time quantitative PCR was performed to analyze the expression of RUNX2 mRNA level and confirmed the adenovirus miR-30a expressed in 143B cells.The expression of RUNX2 was analyzed by Western blot .miR-30a target to RUNX2 was verified by luciferase reported gene assay .Results The ability of migration and invasion was suppressed in osteosarcoma cell 143B by overexpression miR-30a,and the cell viability also decreased .After the endogenous miR-30 a being inhibited , the cell motility and invasion enhanced and the cell viability was promoted .The RUNX2 protein decreased after overexpression miR-30 a as compared with controlgroup.TheluciferaseactivityofRUNX2decreasedbyaddingmiR-30a.Conclusions 143Bcellmigration, invasion and viability were suppressed by miR-30a,and this process is potentially achieved via suppressing RUNX 2 protein expression .

Objective To observe CT features of ovarian thecofibroma and the clinical significance.Methods CT manifestations, clinical data and pathological diagnosis of 12 cases of ovarian thecofibroma proved by pathology were retrospectively analysed.Results The CT manifestation of ovarian thecofibroma was typical,which was showed as following:on one side of the attachment area tumor,single,ovoid or class circular shape,most boundary clear,equal or slightly low density solid masses,internal or boundary ar-ea accompanied by a small amount low density area,mild delay enhancement in solid ingredients or no obvious enhancement.Conclu-sion CT examination is important for qualitative diagnosis of ovarian thecofibroma and finding complications.

Objective To explore the influence of telephone follow-up after discharge on the re-admission rate of patients with chronic heart failure.Methods In total,161 patients were randomly divided into the observation(n=81)and control group (n=80).All participants received conventional guidance following discharge from our hospital.The patients in the observation group were subject to telephone follow-up for 6 months and individualized caring intervention.The re-admission rates after 6 months after discharge between two groups were statistically compared.Result The re-admission rate in the observation group was 30.9%, significantly lower compared with 42.5% in the control group(P<0.05).Conclusion The telephone follow-up combined with individualized caring intervention can reduce the re-admission rate among the patients with chronic heart failure.

Objective To investigate the clinical efficacy of bronchoscopic MMC topical spraying for the treatment of tuberculous cicatricial stenosis of the central airway. Methods 45 patients with t tuberculous cicatricial stenosis of the central airway were randomly divided into a control group (14 patients), treatment group 1 (group1, 15 patients), or treatment group 2 (group 2, 16 patients), who received bronchial balloon dilatation alone, bronchial balloon dilatation combined with topical MMC spraying for one time, and for twice, respectively . The clinical efficacy was observed by using the MRC score and measuring airway diameter at the time points before treatment, end of treatment, and 3, 6, and 12 months after treatment, respectively. Results For the MRC scores at different time points, the MRC scores in group 2 (0.06 ± 0.25) and group 1 (0.33 ± 0.617) were significantly lower than those in the control group at 3 months after treatment (P < 0.05 for all comparisons);there were nosignificant differences at the other time points among the three groups. For the airway mean diameters at the different time points, the airway mean diameter was higher in group 2 than in the control group at 3 and 6 months after treatment (P < 0.01), and in group 1 at 3, 6, and 12 months (P < 0.05). No statistical differences were found in the other time points among three groups (P > 0.05). Conclusions Bronchial balloon dilatation combined with topical MMC spraying has certain short-term and long-term efficacy for improving dyspnea and maintaining the airway diameter after dilatation.

Objective To explore the characteristics of gait and surface electromyography (sEMG) of underwater treadmill training (UWTT). Methods From January to September, 2015, gait and sEMG parameters of ten healthy adults were synchronously collected using three-dimensional gait analysis system and sEMG systems on land and UWTT. Results When walking in self comfortable speed, compared with walk on land, there was significant increase in gait cycle (t=-11.411, P<0.001) and percentage of the swing phase (t=-5.252, P<0.05), significant reduction in walking speed (Z=-2.803, P<0.01) and step frequency (t=7.421, P<0.001). There was no significant difference in step strength (Z=-0.357, P>0.05). The integral electromyography of biceps femoris, gastrocnemius, tibialis anterior muscle were significant less than iEMG on land (t>3.984, P<0.01), but no significant difference of rectus femoris (t=0.054, P>0.05). Conclusion There are signifi-cant differences in gait and muscle contraction intensity between land walking and UWTT. The dynamic physiology and neural control of UWTT need further study.
