Objective To study the sonographic features of papillary thyroid carcinoma (PTC) associated with cervical lymph nodes metastasis for early diagnosis and prediction of the invaded cervical lymph nodes. Methods The sonographic features of 170 patients with pathologically confirmed PTC in First Afifliated Hospital of Harbin Medical University between 2011 and 2013 were retrospectively reviewed. There were 59 cases with neck lymph nodes metastases and 111 cases without neck lymph nodes metastases. Receiver operating characteristic (ROC) curve was aaplied to analyze the cut-off values of resistance index (RI) and peak systolic velocity (PSV) for judging the presence or absence of cercical lymph node metastasis. The Chi-square test and rank sum test were used to compare the different sonographic features between each group. The Logistic regression analysis was used to obtain the relevant factors of PTCs with cervical lymph node metastasis. Results ROC curve analysis showed that the cut-off values of RI and PSV were 0.735,13.95 cm/s. The primary tumor diameter, the existence of halo, the involvement of thyroid upper pole, the microcalciifcation, the blood suply classiifcation and the RI, PSV were statistically signiifcantly different between PTCs with and without cervical lymph node metastasis, whereas no statistical signiifcance was detected between the primary tumor echo pattern, boundary and the longitudinal/transveral ratio between the metastatic and nonmetastatic group. Logistic regression analysis showed that the PTC primary tumor diameter and PSV were independent factors coorelated with cervical lymph node metastasis. Conclusion Some sonographic features of PTC are closely correlated with lymph nodes metastasis, which are valuable in predicting the cervical lymph nodes metastasis in patients with PTC pre-operatively.

Objective To explore the efficacy of foreskin-deglove and shaft-fix procedure combined with Z-plasty of penis and scrotum skin in the treatment of concealed penis. Methods Fifty-eight patients diagnosed as concealed penis were included in the study.All of them underwent the foreskin-deglove and shaft-fix procedure.Foreskin was degloved from 5 mm to 10 mm proximal to corona deep to the root,and bilateral tunica albuginea at this level was sutured to suprapubic scarpas' fascia.Z plasty of penis and scrotum skin was applied to cover penile shaft. Results After follow-up for 6 to 12 months,there was no recurrent retraction of the penile shaft,and all the patients were satisfied with the appearance of penis after plastic surgery.Edema of prepuce occurred in 2 patients,and completely regressed in 2 to 3 months.There was no incision scar hyperplasy,and the function of urination and erection were normal. Conclusion Foreskin-deglove and shaft-fix procedure combined with Z-plasty of penis and scrotum skin can resolve pathologic problems of concealed penis and has favourable aesthetic results with less complications.It is easy to perform and is an ideal procedure in the treatment of concealed penis.

AIM:To explore the effect of HbA1c level in the patients with type 2 diabetes mellitus (T2DM) on the rheological properties of erythrocytes and the structure of hemoglobin (Hb).METHODS:The patients with T2DM were classified into 3 groups:the patients with good glycaemic control (group A, HbA1c<7.0%), the patients with poor glycaemic control (group B, 7.0%≤HbA1c<9.0%) and the patients with persistent hyperglycemia (group C, HbA1c≥9.0%) .The rheological properties of a single living erythrocyte were analyzed by the techniques of static imaging and anal -ysis.Ultraviolet-visible spectroscopy was used to study the structure of Hb .RESULTS: Compared with group H , the roundness effect factor (REF) of erythrocytes, which was positively related with HbA1c level, was significantly increased in groups A, B and C (P<0.05).The contact area of erythrocytes in group B and all the morphological parameters of erythrocytes in group C were significantly higher than those in group H ( P <0.05 ) .There were significant differences among groups A , B and C in deformation capacity and elastic parameters of the cell membrane ( P<0.05 ) , but with no difference in the long axis and short axis between group A and group B .Compared with group H , no obvious change in the spectral pattern and spectrum peak of Hb in groups A , B and C was observed.However, the absorbance of Hb, which showed a trend of gradual decline with the increase in HbA 1c level, in group B and group C was significantly decreased as compared with group H (P<0.01), and the Hb absorbance in group C were also lower than that in group A (P<0.05). CONCLUSION:With the increase in HbA1c level, the morphology along with the deformation function of erythrocytes in T2DM changes and declines gradually , and the structure of Hb may also change .

AIM: To investigate the effect of interleukin-13 (IL-13) on cell proliferation and interleukin-6 (IL-6) production in mesangial cells. METHODS: Cell proliferation was tested by MTT method. The protein synthesis of IL-6 in mesangial cells was measured by ELISA. The expression of IL-6 mRNA in mesangial cells was evaluated by RT-PCR. RESULTS: IL-13(1 ?g/L-100 ?g/L) inhibited the proliferation of mesangial cell in a dose-dependent manner. Both mRNA and protein of IL-6 in mesangial cells were increased significantly in the presence of LPS and this increase could be reversed by IL-13 (1?g/L-100?g/L). However, this increase could not be reversed by IL-13 if the dose was lower than 0.1?g/L and if the mesangial cells were cultured in 5% FCS RPMI1640. CONCLUSION: IL-13 could inhibit IL-6 expression induced by LPS in mesangial cells . We suggested that IL-13 may be an inhibitory cytokine in the regulation of the mesangial cell proliferaltion and inflammatory reaction in glomerulonephritis.

Objective To investigate the prevention and management of perioperative complications of intertrochanteric fractures in elderly in-hospital patients(aged≥80 years).Methods Clinical data of 103 intertrochanteric fracture patients(31 male and 72 female)undergoing surgical treatment at our hospital from May 2010 to Nov.2015 were retrospectively analyzed.Their ages ranged from 80 to 99 years,with an average of 86.2 years.There were 3 Evan type Ⅰ cases,25 type Ⅱ cases,36 type Ⅲ cases,37 type Ⅳ cases and 2 type V cases.Of these,82 received epidural anesthesia and 21 had general anesthesia.Intertrochanteric fractures were treated with proximal femoral nail(PFN) internal fixation in 101 patients and dynamic hip screw(DHS)internal fixation in 2 patients.Results The average operation duration and blood loss were 30 min and 60 ml in the PFN internal fixation group and 60 min and 150 ml in the DHS internal fixation group,respectively.The average hospitalization time was 16.7 days.One patient (0.9％) died after operation,10 (9.7％) had preoperative complications of bed rest with 3 cases involving the central nervous system and 4 cases involving the respiratory system,and 38 cases (36.9％)had postoperative complications with 13 involving the central nervous system.The average time from admission to operation was 6 days,with 65 cases above the average and 38 cases below the average,and there was a statistically significant difference in the incidence of postoperative complications between the two subgroups(30/65 or 46.2 ％for the former and 8/38 or 21.1％ for the latter,x2＝6.49,P＜0.05).Conclusions Elderly patients with intertrochanteric fractures should undergo surgery as soon as possible,preferably with epidural anesthesia.Proficiency in surgical kills,short operation time,close monitoring of preoperative and postoperative conditions,and proper and timely treatment are the key to ensuring surgical success.

OBJECTIVE: To assess the effect of disinfectant (Cavicide) with benzethon chloramine and isopropanol as main active ingredients disinfectant on dental impression accuracy. METHODS: The effect of Cavicide on three impression materials (alginate, polyether and vinylpolysiloxane) were assessed using a standard model. The standard model was digitized by an extraoral scanner (IScan D103i, Imetric). For each kind of impression materials, thirty impressions were taken following the manufactures' instruction in the same conditions. Subsequently, the impressions were randomly divided into three groups, with ten impressions in each group. After the impression taking was completed, the three groups underwent pure water rinse for 1 min (blank control, BC), 2% glutaraldehyde solution immersion disinfection for 30 min (glutaraldehyde, GD), and Cavicide solution spray disinfection for 5 min (Cavicide, CC), respectively. All the impressions were digitized by the extraoral scanner (IScan D103i, Imetric) after disinfection and exported to a dedicated three-dimensional analysis software (Geomagic Qualify 2014, Geomagic, USA). In the software, the digital models of the impressions were trimmed to teeth and then superimposed with the digitized standard model via best-fit alignment. Root mean square (RMS) was used to evaluate the deviations between the impression and the standard model. The deviation in the anterior and posterior regions was evaluated respectively. One-way ANOVA test and the LSD post-hoc test were used to compare the deviations between the three groups (P < 0.05). The color map of each superimposition was saved for visual analysis. RESULTS: For the polyether and vinylpolysiloxane materials, the difference between the three groups was not statistically significant (P=0.933, P=0.827). For the alginate material, the difference in posterior region between group GD and group BC, as well as group GD and group CC were statistically significant (GD vs. BC, P=0.001; GD vs. CC, P=0.002), while the difference between group BC and group CC was not statistically significant (P=0.854). The visual analysis showed an obvious deviation in the buccal-lingual direction in group GD. CONCLUSION Disinfectant (Cavicide) with benzethon chloramine and isopropanol as main active ingredients using spray disinfection has no effect on the accuracy of the alginate, polyether and vinylpolysiloxane impressions.

OBJECTIVETo evaluate the clinical efficacy of treating myelodysplastic syndrome (MDS) by hematopoietic stem cell transplantation (HSCT) combined with Chinese medical syndrome typing.

METHODSFrom July 2009 to July 2013, 6 MDS patients were treated with allo-HSCT combined with Chinese medical syndrome typing from HLA-identical sibling donors at Department of Hematology, Zhejiang Provincial Hospital of Chinese Medicine. Patients were classified as refractory anemia (RA, 2 cases), refractory anemia with ringed sideroblast (RARS, 1 case), refractory cytopenia with multilineage dysplasia (RCMD, 2 cases), and RA with excess blasts-I (RAEB-I , 1 case). Modified BuCy conditioning regimen was used in all 6 cases. Two patients received bone marrow transplantation (BMT), 1 patient received peripheral blood stem cell transplantation (PBSCT), and 3 patients received BMT + PBSCT. In order to prevent the occurrence of graft-versus-host disease (GVHD), all patients were treated with cyclosporine + methotrexate + mycophenolate mofetil. Different Chinese medical treatment methods (by syndrome typing) were given to patients according to different criticality of international prognostic scoring system (IPSS, 5 at moderate risk and 1 at high risk).

RESULTSAll 6 patients successfully reconstructed their hematopoietic system. The time from transplantation to ANC ≥ 0.5 x 10(9)/L and platelet (PLT) ≥ 20 x10(9)/L were 13 (9-15) days and 11 (9-22) days respectively. Main complications were GVHD. Acute GVHD (aGVHD) occurred in 4 cases, 3 cases of grade I and 1 case of grade II, and local chronic GVHD (cGVHD) occurred in 1 patient. All cases survived with median follow-up of 18 (11-58) months. The overall survival (OS) and disease-free survival (DFS) rate were 100%.

CONCLUSIONSHSCT combined with Chinese medical syndrome typing could improve clinical symptoms, reduce transplant as- sociated complications. So it was an effective treatment choice for MDS.
