Objective To investigate the immunological reaction mechanism of medicated serum in Zibai Gelatin for SiHa cells of the cervical cancer infected by high risk human papilloma virus (HPV). Methods Through immunohistochemical comparison and the cell culture, and after medicated serum was administrated to SiHa cells of cervical cancer for 24 h, 48 h, and 72 h, optical densities of IL-6, IL-10, CD83 and TNF-αin the same time but different concentrations and different times but the same concentration were observed. Relationships of dose-effect and time-effect between expressions of IL-6, IL-10, CD83 and TNF-α and medicine action were analyzed by calculating average optical density. Results With the increase of medicine concentration and administration time of Zibai Gelatin, the expressions of IL-6 and TNF-αgradually decreased, while the expressions of CD83 and IL-10 gradually increased (P<0.05). Conclusion Zibai Gelatin with medicated serum can inhibit local inflammatory reaction by improving local immunologic function of cervix, which is beneficial to reduce cervix high-risk HPV.

Objective To summarize our experience on diagnosis and treatment of bilateral primary breast cancer (BPBC). Methods Clinicopathologic records, including clinical manifestations, diagnosis and immunohistochemical expressions of 16 patients with BPBC, treated from 2001 to 2009 in Jiangsu Provincial Cancer Hospital, were analyzed retrospectively. Results The 16 patients with BPBC accounted for 0.47% of all patients diagnosed as malignant tumors of breast during the same period in our hospital. All of the 16 patients were women, with the median age of 53 years (ranged 41-69 years). 7 patients were in bilateral synchronous breast cancer (BSBC), with the median age 47 years (ranged 41-54 years), among whom 5 patients got BSBC just before menopause. 9 patients were in bilateral asynchronous breast cancer (BABC), with the median age 58 years (ranged 43-69 years), among whom 1 patient got BABC before menopause. The median interval between the first and second breast carcinoma of BABC was 52 months (ranged 14-196 months). Conclusions Compared with BABC, the occurrence age of the patients with BSBC was smaller. BABC was more common in premenopausal women. The interval time of BABC was irregular. The active follow-up after the occurrence of contralateral breast cancer and endocrine therapy for estrogen receptor-positive patients were recommended.

[ ABSTRACT] AIM:To observe the influences of different concentrations of MG132 on apoptosis and beta-amyloid protein ( Aβ) generation in SH-SY5Y cells, and to explore the underlying mechanism.METHODS:SHSY-5Y cells were incubated with MG132 for 24 h.The final concentrations of MG132 were 2.5, 5 and 10μmol/L.The cell viability was de-termined by MTT assay.The cell apoptosis was assessed by flow cytometry.The levels of Aβwere measured by ELISA. The relative protein levels were detected by Western blot.RESULTS:In the SH-SY5Y cells, MG132 reduced the cell via-bility, induced the cell apoptosis, increased the level of Aβ, and increased the expression of the related proteins for Aβgeneration in a concentration-dependent manner.CONCLUSION: MG132 induces apoptosis and increases the levels of Aβ1-42 and Aβ1-40 by regulating the proteins related to Aβgeneration in the SH-SY5Y cells.

Objective To provide anatomical basis for elevating iliac tissue flap pedicled on the iliolumbar artery.Methods The course,number,outer diameter and distribution of iliolumbar artery were observed on 13 human cadavers.Results All the iliolumbar artery originated from the internal iliac artery.The iliolumbar artery gave off 2 branches (iliacus branch and lumbar branch) when passing between the obturator nerve and the lumbosacral trunk,posteriorly to the psoas major.The mean distance between origin of the iliolumbar artery and bifurcation point to iliacus and lumbar branches was 7.1 (7.1 ± 0.5) cm.The iliacus branch divided into two branches:one artery curved forward and anastomosed with the iliacus branch of deep circumflex iliac artery; the other artery supplied the tissue around the posterior superior iliac spine.The lumbar branch supplied the psoas major and the quadratus lumborum.Conclusion The iliolumbar artery and the iliacus branch is one of the most constant and reliable vessels supplying the iliac bone,and can be used as the pedicle of free or pedicled iliac tissue flaps.

Educational reform of pathophysiology oriented to clinical application is to pass the physician qualifica -tion examination .One of essential approach is to implement pathophysiology teaching with the translational medical philosophy and promote the harmonious development of physician -patient relationship with the utilization of the de-velopment and changes of disease in the teaching process .In that way, the pathophysiology in basic and clinical medicine is worthy of the name of “bridge”, and ultimately achieves the goal of “the transformation and develop-ment of the cultivation of clinical application talents”.

Objective To summarize the clinical experienee in surgical treatment for hepatocellular carcinoma (HCC). Methods The clinical data of 7566 HCC patients who had been admitted to Research Institute of Liver Cancer of Fudan University from January 1988 to Deeember 2007 were retrospectively analyzed. The overall survival and recurrence free survival (RFS) rates were eaeulated with Kaplan-Meier survival curve. All the data were analyzed using Log-rank test and Cox regression model. Results The 3-, 5-, 10-year overall survival and RFS rates of 7164 patients with HCC resection were 56.29%, 41.76%, 26.70%, and 63.92%, 56.12%, 42.97%, respectively, and the perioperative mortality was 1.54%. The 5- and 10-year overall survival rates of patients with small HCC (diameter<5 era) were 58.20% and 38.47%, which were significantly higher than 31.42% and 20.43% of patients with large HCC (diameter >5 cm) (X2 =535. 568, P <0.01). The 5-year overall survival rotes of HCC patients with resection after down-staging (n = 110), re-resection after recurrence (n = 515), and tumor thrombus in portal vein (n = 168) were 51.26%, 67.28% and 26.81%, respectively; nd the 5-year DFS rotes were 77.44%, 13.01% (calculated from the first operation) and 34.90%, respectively. The 3- and 5-year overall survival and DFS rates of 402 patients who had undergone liver transplantation were 60.81%, 55.63% and 64.47%, 58.52%. The independent prognostic factors influencing the overall survival and DFS rates were the size, number and differentiation of HCC and intrahepatic vessel invasion (X2 = 200.539, 27. 536, 96.964,216. 156, P <0.01). Conclusions Early screening, improved safety of surgery, combined therapy and breakthrough in the reseaeh of preventing HCC metastasis and reeurrenee will significantly improve the treatment outcome of HCC.

Objective To compare patellar ring,Kirschner wire tension band and patellar ring plus Kirschner wire in fixation for treatment of patella fractures.Methods A retrospective analysis was conducted on the 285 patients with patellar fracture who had been treated between September 2009 and January 2016.They were 155 men and 130 women,with an average age of 45.5 years (from 18 to 70 years).Their fractures included 176 transverse,28 longitudinal split and 81 comminuted ones.They were divided into 3 groups according to their different internal fixation methods:patellar ring fixation (98 cases),Kirschner wire tension band (92 cases),patellar ring plus Kirschner wire fixation (95 cases).The 3 groups were compared in terms of operative time,intraoperative bleeding,fracture healing time,knee function by B(o)stman score at the last follow-up and postoperative complications.Results The operative time in the patellar ring group(58.9 ±6.4 min) was significantly shorter than in the Kirschner wire group (71.8 ± 7.8 min) and in the patellar ring plus Kirschner wire group (74.4 ± 8.0 min) (P ＜ 0.05).There were no statistical significant differences between the 3 groups in fracture healing time and intraoperative bleeding (P ＞ 0.05).The good to excellent rate of knee function at the last follow-up in the Kirschner wire tension band group was 100.0％ (92/92),significantly higher than in the patellar ring group (90.8％,89/98) and in the patellar ring plus Kirschner wire group (91.6％,87/95) (P ＜ 0.017).There was no significant difference in postoperative complication rate between the patellar ring fixation group (2.0％,2/98),Kirschner wire tension band fixation group (1.1％,1/92) and the patellar ring plus Kirschner wire group (2.1％,2/95) (P ＞ 0.05).Conclusion Internal fixation with Kirschner wire tension band has definite curative effect on patellar fractures,showing the advantages of less operative invasion,fewer postoperative complications,better functional recovery of the affected knee joint,and lower price over the other 2 internal fixation methods.
