OBJECTIVE: To explore the expression and significance of programmed cell death 5 (PDCD5) and Bcelllymphoma/lewkmia-2(Bcl-2) in sinonasal squamous cell carcinoma (SNSCC). METHOD: Immunohistochemical method and Western Blot method was used to determine the expression of PDCD5 and Bcl-2 in specimen of SNSCC in thirty cases, sinonasal inverted papillomas (SNIP) in thirty-eight cases, and normal nasal mucosa in twenty cases. RESULT: (1) The expression of PDCD5 protein in SNSCC significantly decreased compared with SNIP and normal nasal mucosa. (2) The expression of Bcl-2 protein in SNSCC up-regulated obviously compared with SNIP and normal nasal mucosa. (3) Positive rate of PDCD5 protein and Bcl-2 protein in well, moderate and low differentiatied group is respectively 100.00%, 83.33%, 38.89% and 50.00%, 70.83% and 100.00%, the difference was statistically significant (P < 0.05). (4) In the follow-up cases, the survival rate of the patients with higher expression of PDCD5 protein was higher, but that with lower expression of Bcl-2 protein was higher. CONCLUSION The inactivation of PDCD5 protein and the activation of Bcl-2 protein may play an important role in the development of SNSCC, and there are a positive correlation between PDCD5 and Bcl-2 protein in SNSCC, which may be identified as a new therapeutic target.

Objective To evaluate the effect ofJiawei-Danggui-Buxue decoction in the treatment for the patients with hemorrhagic anemia after total knee arthroplasty (TKA).Methods A total of 63 TKA patients with hemorrhagic anemia were included, and were divided into the treatment group (31 patients) and the control group (32 patients). All patients started to take medicine the second day after surgery. The control group took the Ferrous Succinate Tablets and the treatment group took Jiawei-Danggui-Buxue decoction in the following 4 weeks. The Hb and Hct were detected,and the changes of TCM syndrome scores and the total effect rates of anemiawere observed.Results The total effect rate of TCM syndrome scores in the treatment group was 93.54%, which was significantly higher than control group 83.87% (P<0.05); The total effect rate of anemia in the treatment group was 90.32%, which is significantly higher than control group 75.00% (P<0.05). At the fifteenth day after operation,. And at the postoperative 29th day, the levels of Hemoglobin (129.61 ± 13.02 g/Lvs. 113.35 ± 15.46 g/L,t=6.245) and Hematocrit (0.45% ± 0.03 %vs. 0.41% ± 0.04%,t=5.962) in the treatment group were significantly higher than those in the control group (P<0.05).Conclusions TheJiawei-Danggui-Buxue decoctionimprovethe Hb, HCT and the clinical effect rates of anemia and TCM syndromes for the patients with hemorrhagic anemia after TKA.

Acute blood loss anemia is the most common surgical complication of total knee arthroplasty. Currently, alloge?neic transfusion has been the major method of managing postoperative anemia. Although allogeneic transfusion can correct anae?mic condition temporarily, it can lead to severe complications, such as postoperative infection, prolongation of physical recovery, increased length of hospital stay, and increased mortality. Perioperative blood management can effectively reduce blood loss and transfusion rate. These strategies mainly focus on three parts:therapy for anemia and autologous blood donation before operation;application of a tourniquet, antifibrinolytic drugs, topical hemostatic agents and acute normovolemic hemodilution during opera?tion; selection of reinfusion systems, restrictive transfusion thresholds, drainage and knee position after operation. Perioperative blood management should run throughout the perioperative period, which mainly aims at reducing blood loss and blood transfu?sion, improving prognosis, promoting the postoperative recovery and lowering the medical cost. Depending on the actual situations of patients, surgeons should combine different major characteristics of each strategy and weigh the pros and cons to make effective and reasonable individualized treatment plan.

Objective To characterize the features of breast mucinous carcinoma on T2WI, dynamic contrast-enhanced MR imaging (DCE-MRI) and diffusion weighted imaging (DWI) and correlate the MR features with histopathology. Methods MR imaging in 8 women (aged 33--65 years old) with mncinous carcinoma of the breast verified histopathologically was performed on 1.5 T scanner with T1WI, FS T2 WI, 3D DCE-MRI using volume imaging for breast assessment(VIBRANT) sequence, DWI with b value of 500 and 1000 s/mm2 by single-shot EPI sequence. According to the lexicon of BI-RADS-MRI designed by ACR, the MR findings were retrospectively studied, including morphology, signal intensity on T1WI and FS T2WI, mass enhancement, the patterns of dynamic enhancement curve, and the mean ADC on DWI. The pathologic diagnosis was made according to the standard criteria by the World Health Organization Classification of Tumors. Results Five patients were pure mucinous carcinoma and 3 patients were the mixed. The amount of mucus ranged from 60% to 90%. All 8 tumors presented as a mass on MRI with low signal intensity on T1WI, high or strongly high signal intensity on FS T2WI and high signal on DWI. The tumor size ranged from 1.3 to 3. 2 cm in diameter. Five tumors showed rim enhancement in early phase and the central part was gradually enhanced in delayed phase. One tumor presented slightly heterogeneous enhancement. Two tumors showed progressively heterogeneous enhancement. The mean ADC values of tumor were (2.41±0.28) ×10-3 mm2/s with b value of 500 s/mm2 and (2.06 ±0. 14) × 10-3 mm2/s with b value of 1000 s/mm2, and higher than that of the normal breast tissue [ ( 1.71 ±0. 32) × 10-3 and ( 1.43 ± 0. 24) × 10-3 mm2/s]. Conclusions The MR features of breast mucinous carcinoma on T1WI, DCE-MRI, and DWI are different from that of invasive ductal carcinomas and may reflect its distinct histological type. The combination of these MR sequences may lead to a pre-operative diagnosis of this tumor.

Aim To observe the effects of tetrahydro-biopterin ( BH4 ) on nitric oxide ( NO ) production in the kidney of type 2 diabetic nephropathy ( DN) mice, and to find a new target for the treatment of type 2 DN. Methods The 12 week-old db/db mice developed in-to DN phase were divided into 2 groups:DAHP group, subjected to intraperitoneal injection of 150 mg·kg-1 DAHP (n=8);DN group, subjected to intraperitone-al injection of same dose of normal saline containing 5% DMSO ( n = 6 ) . The age-matched db/m mice ( NS group) were subjected to intraperitoneal injection of same dose of normal saline containing 5% DMSO ( n =6 ) . Three groups of mice were treated for 7 days. Then the fasting blood-glucose, serum creatinine, u-rine protein and activity of iNOS were determined by chemical colorimetry. And the iNOS protein in renal cortex was determined by immunohistochemisty and western blot, respectively. BH4 was measured by HPLC method. NO level was determined by Griess method. Results The levels of fasting blood-glucose, serum creatinine, 24h urine volume, 24h urine pro-tein, BH4 , iNOS and NO in DN group were signifi-cantly higher than those in NS group;The levels of ser-um creatinine, urine volume, urine protein, BH4 , iN-OS and NO in DAHP group were significantly lower than those in DN group. Conclusion In the kidney of type 2 DN mice, the increased BH4 contributes to over-production of NO by the increased iNOS expression, and resultes in the increase of urine volume and urine protein.
