Objective To investigate the expressions of AGGF1 in esophageal squamous cell carcinoma (ESCC) and their relationships with clinical features and prognosis of ESCC. Methods The expressions of AGGF1 in 70 cases of ESCC and 30 cases of normal esophageal tissue were examined using SP immunohistochemical staining and were analyzed according to the clinical features and follow-up data. Results The expressions of AGGF1 in 70 cases of ESCC was significantly higher than those in 30 cases of normal esophageal tissue [54.29%(38/70) vs. 23.33%(7/30)](P=0.004). The expressions of AGGF1 in ESCC were significantly related to the TNM stage, clinical stage and prognosis (P all<0.05). The OS was shorter in the positive teams of AGGF1 than that in the negative teams [(19.7 ± 3.5) months vs. (33.2 ± 4.0) months] (P=0.015). Cox- proportional multivariate analysis showed that positive expressions of AGGF1 and VEGF (P=0.043, 0.024) and clinical stage (P=0.035) were significant prognostic factors in overall survival. Conclusions AGGF1 has high expressions in ESCC, and it is closely related to the clinical features and prognosis of ESCC.

Objective To establish a simple and practical superparamagnetic immunochromatographic test strip for rapidly monitoring human serum level of CA72-4. Methods Water-soluble carboxylated super-paramagnetic nanoparticles were prepared with a modified one-step hydrothermal synthesis method. Magnetic probe was prepared by immobilizing specific antibody (mAb1) onto the surface of nanoparticles. Following with optimization and assembly of the test strip , we evaluated sensitivity , specificity , stability of this method for serum CA72-4 detection. Results The optimized test strip provided not only the qualitative results, but also the high sensitivity quantitative detection through stable magnetic signal. The detection limit was 0.83 IU/mL. One hundred clinical samples ( 70 positive and 30 negative ) were measured to assess these test strips with high sensitivity (99%) and high specificity (93%). The test strip and magnetic signal possessed high stability. Conclusion A rapid and quantitative detection of CA72-4 by the test strip was accomplished. This method is rapid, sensitive and quantitative, possessing great potential in large sample screening or in-home testing.

Intensity-modulated radiotherapy (IMRT) is gradually replacing conventional radiation therapy and has become the mainstream radical treatment for patients with nasopharyngeal carcinoma (NPC). IMRT can conform and increase radiation doses to tu-mor-associated regions as well as decrease exposure doses and volumes on normal organs and tissues to avoid damage on critical or-gans. Aside from system and setup errors, other factors, such as the gradual reduction of the primary NPC lesion and the decrease in vol-ume of involved neck lymph nodes as well as body weight loss and changes in the head and neck shape during IMRT, may cause devia-tions in the radiation doses and volume delivered to the NPC targets and the organs at risk. These factors may affect the accuracy of IMRT. Several researchers have attempted to correct such deviations during IMRT for NPC patients by using adaptive radiotherapy (ART). The results indicate that ART is feasible to a certain degree and can correct the deviations, including decrease in tumor volume, body weight loss, and changes in head and neck shape of NPC patients.

Objective To explore the hierarchical chain management model of type 2 diabetes and determine its evaluation.Method Based on the hierarchical chain management of the three community health service institutions and Dahua hospital in Shanghai Xuhui district,215 cases of type 2 diabetes had been involved in the study.Results Compared with the baseline before management,lasting blood glucose (FBG),2 h postprandial glucose (2hPBG),glycosylated hemoglobin (HbA1c),low density lipoprotein cholesterol (LDL-C),systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the diabetes after 12 months' management declined [(8.50 ±2.81) mmol/L,(11.09 ±4.01) mmol/L,(8.56 ±2.41)% ,(3.31 ± 1.06) mmol/L,(139.06 ±20.68) mm Hg (1 mm Hg = 0.133 kPa),(78.20 ± 12.11) mm Hg vs.(7.41 ±2.04) mmol/L,(9.03 ±2.46) mmol/L,(7.34 ± 1.59)% ,(3.00 ± 1.06) mmol/L,(135.48 ± 17.82) mm Hg,(77.27 ±11.83) mm Hg],and the differences were statistically significant(P＜0.01 );control rate of FBG,2hPBG,HbA1c,LDLC,SBP,DBP had improved significantly [19.5% (42/215),20.9% (45/215),24.7%(53/215),20.0%(43/215),27.4%(59/215),30.2%(65/215) vs.50.7%(109/215),53.0% (114/215),54.0%(ll6/215),42.3%(91/215),47.0%(101/215),45.6%(98/215)](P＜0.01).Conclusion Primary and secondary-care hospital based hierarchical chain management model is valid and can be implemented for type 2 diabetes.

Objective To investigate the relationship and mechanism of the heme oxygenase-1 expression in peripheral blood mononuclear cells (PBMC) and the oxidative stress in diabetic nephropathy. Methods Two groups of diabetic patients with or without diabetic nephropathy and a normal control group were enrolled in this study. Fasting blood glucose (FBG), HbA1c, serum MDA level, ROS level, HO-1 mRNA level and HO-1 protein expression in PBMC were determined. Results In control group, diabetic group and diabetic nephropathy group , the MDA levels significantly increased[(14.23±5.07)nmol/ml vs (24.90±7.12)nmol/ml vs (43.83±16.97)nmol/ml](F＝37.022,P＜0.01), the ROS levels significantly increased (113.18±58.59 vs 364.54±88.67 vs 524.35±162.51)(F＝68.369,P＜0.01) and the HO-1 protein expression also increased significantly (22.84±9.98 vs 36.72±15.85 vs 58.1±15.93)(F＝31.302,P＜0.01). There was a positive correlation among the HO-1 mRNA, protein expression and MDA level(r＝0.407,0.429,P＜0.05). Conclusions There existed a severer oxidative stress condition in patients with diabetic nephropathy compared with the patients without diabetic nephropathy. HO-1 could be a potential pathway to ameliorate oxidative stress in diabetic kidney disease patients.

Water deprivation and loading tests were performed in a patient with sustained hypernatremia and hypodypsia. Results suggested that the regulation of ADH release was still retained despite of the raised threshold, being consistant with the diagnosis of essential hypernatremia. The hypernatremia of this patient was partially improved by dihydrochlorothiazide and desmopression acetate (DDAVP).

Under the guidance of meridian theory, the acupoints heat-sensitive moxibustion is a treatment method which applies moxa stick to perform mild moxibustion at heat-sensitive acupoints, which can arouse the meridian sensation transmission and promote the movement of meridian qi; consequently, the qi can be extended to the diseases. For its many advantages, such as no direct contact on skin, no injuries, no pains, fewer side effects, easy operating and moderate cost, the acupoints heat-sensitive moxibustion is widely accepted in dermatology, male urology disease, rectum and anus diseases and breast diseases. The application and research status of the acupoints heat-sensitive moxibustion in traditional Chinese surgery in recent years is reviewed, and several problems and suggestions in its clinical application and research are proposed, aiming to provide clinical basis for its further development and clinical application in traditional Chinese surgery.

A 19-year-old female presented with a dark erythematous maculopapule measuring 2 cm in diameter on the left lower limb for more than one year.Physical examination revealed an enlarged cherry-like lymph node in the right inguinal region.Histopathology of the lesion revealed that the normal structure of skin disappeared absolutely,and there was a diffuse infiltrate of medium-sized lymphoid tumor cells with unclear nucleoli.Immunohistochemically,the tumor cells strongly expressed CD4,CD56 and CD123,and partially expressed terminal deoxynucleotidyl transferase (TdT).Flow cytometric analysis of bone marrow aspirates showed that abnormal cells amounted to 59.9％,and were positive for CD123st (strong),human leucocyte antigen-DRst (strong),CD56,CD304 (blood dendritic cell antigen-4),CD7,CD11b,CD33,CD36 and chemokine (C-X-C motif) receptor 4,CD13 (dim),CD4 (partial) and CD117 (partial).Transmission electron microscopy of bone marrow cells revealed that there were massive uniformly sized lymphoid cells with thick processes on cell surfaces,a high nucleus/cytoplasm ratio,centrally located round nuclei occasionally with deep gyrus-like notches,clumped marginated heterochromatin and multiple nucleoli.Moreover,a small amount of cytoplasm was observed in the lymphoid cells with the presence of mitochondria and endoplasmic reticulum arranged in concentric circles,which were characteristic of plasma cells.The features of both dendritic cells and plasma cells were found in the tumor cells through transmission electron microscopy.Based on the above findings,a diagnosis of blastic plasmacytoid dendritic cell neoplasm (BPDCN) was made.

Objective To study the CBCT image registration of PTV enlarging distance and IMRT planning(CT-1) for patients with lung cancer,and evaluate their characters.Methods Ten patients with lung cancer were included in the study.Two sets image,before and after radiotherapy,were acquired every week.Then delineated the targeted volume and made the planning (CT-2) according the enlarging distance data.To comparize the parameters of DVH for lung and spinal cord,volumes and dose of PTV and NTCP with CT-1 and CT-2.The difference of two plan was analyzed by covariance analysis or Wilcoxson's z-test.Results The max,min and mean dose of PTV,the lung V5,V10,V20,V30,V50 were similar in both plans (P =0.242-0.663).There was superiority in CT-2 of PTV and lung's mean dose(P =0.049,0,035).The NTCP had the decent tendency followed by the increasing of lung Vs,V10,V20(P =0.146,0.053,0.000).Conclusions CBCT based image registration can reduce PTV,the mean dose of lung,NTCP,and increase PTV dose.This provides a tool for exploring acurate radiotherapy strategies.

OBJECTIVE:To analyze intervention effect of Drug Rational Usage Guidelines System(DRUGS)on antibacterial agents use in department of obstetrics and gynecology in our hospital. METHODS:The application of antibacterial agents in depart-ment of obstetrics and gynecology in our hospital during Jan.-May(before intervention)and Jun.-Nov. 2012(after intervention)were extracted in respects of drug name,preoperative medication duration,perioperative additional condition,postoperative drug with-drawal time,drug combination,usage and dosage,average hospitalization stay,hospitalization cost. The intervention effects were analyzed. RESULTS:After intervention,the type of antibacterial agents were more in line with national regulations;the proportion of type Ⅰ incision surgery without antibacterial agents increased from 57.8% to 75.2%;the prophylactic application of antibacteri-al agents in type Ⅱ incision surgery within 0.5-2 h increased from 80.2% to 97.0%. The rate of reasonable antibacterial selection, drug combination,usage and dosage increased from 76.9%,64.9%,71.3% to 89.3%,84.6%,90.2%,respectively. The average hospitalization stay and antibacterial cost per capita decreased significantly. There was statistical significance among above indica-tors before and after intervention(P<0.05 or P<0.01). CONCLUSIONS:DRUGS effectively change irrational use of antibacterial agents in department of obstetrics and gynecology,which provide a new method for the management of antibacterial agents.
