Pericellular matrix (PCM) is a narrow tissue region surrounding chondrocytes, which "chondron" with its enclosed cells. A number of studies suggested that PCM is rich in proteoglycans, collagen and fibronectin, and plays an important role in regulating microenvironment of chondrocytes. Direct measures of PCM properties through micropipette aspiration technique showed that PCM was different from mechanical property of chondrocytes and nature extracellular matrix. However, the function of PCM is not clear, and need further study.

Mice was stimulated by peptidoglycan from Lactobacillus sp and detect cytokines production。It was found that PG induced the production of inflammatory cytokines (IL-1,TNF-? in peritoneal macrophages,IFN-? in spleen cell)and did not induce the IL-2 production in spleen cell. Affymetrix MOE430A genechip was used to analyze changed gene expression of immune cells. It was found that expression of cytokines and related genes were changed under peptidoglycan administration. This might induced by activation of TLR-NF-?B signal pathway.

OBJECTIVETo investigate the placement of a long tube into the small intestine under fluoroscopic guidance and to evaluate its decompression effect on early postoperative small bowel obstruction (EPSBO).
METHODSFifty-four patients with EPSBO requiring decompression between April 2010 and July 2014 were enrolled in the study. Insertion of a long tube was guided by fluoroscopy. We first used the guide wire to pass the pylorus and then used the 10 Fr feeding tube as an exchangeable tube to put the superstiff wire into the duodenum. Finally the long tube could be passed over the guide wire through the pylorus into the intestine. The total procedure time, the radiation exposure time, and the incidence of complications were evaluated.
RESULTSThe long tubes passed into the jejunum on initial insertion for all patients, so the success rate of this technique was 100%. The long tube was inserted into ileum in 18 patients. The mean total procedure time was 34.4 ± 8.6 minutes, and the mean radiation exposure time 18.9 ± 6.8 minutes. A total of 47 patients (87%) experienced full recovery following long-tube decompression and without the need for surgical intervention.
CONCLUSIONSUsing the wire-exchange technique, it is easy to place a long tube into the small bowel under fluoroscopic guidance. This decompression method is safe and effective for management of EPSBO.

The role of autophagy is known to be highly complex and context-dependent, and may be characterized as both tumor suppression and tumor promotion in some tumors, such as breast cancer and prostate cancer. This review outlines recent advances in the studies of the involvement of autophagy in the development, progression and treatment of prostate cancer, focusing on autophagy modulation during androgen deprivation, with a special discussion on the regulatory effect of androgens on the autophagy of prostate cancer cells. A critical evaluation and analysis of the studies suggests that autophagy inhibition combined with androgen deprivation therapy is a promising approach to the treatment of prostate cancer.

7.Research progress in co-delivery of gene and chemotherapy drugs with nanocarriers for cancer therapy.
Acta Pharmaceutica Sinica 2013;48(7):1091-1098
Current trends in nanotechnology and RNA interference technology have made the application of nanocarriers (NCS) as a novel gene and drug delivery systems very promising for the field of multidrug resistance (MDR) cancer treatment. Co-delivery of gene and chemotherapy drugs with NCS has a good synergistic effect compared with the traditional chemotherapy which can increase the amount of the drug distribution in target organ in order to reduce the toxic side effects thereby enhancing efficacy. Therefore, the advent of co-delivery systems with NCS especially in the clinical treatment of MDR has had a significant impact on the cancer treatment.

OBJECTIVETo explore biomechanical properties and stress-strain of mucosa scars after cleft palate surgery.
METHODSAfter the model of mucosa scars was made, the mucosa scars and normal mucosa were excised and examined immediately by tensionometry.
RESULTSThe mucosa scars after cleft palate surgery were compared with normal mucosa. The Poisson's ratio of mucosa scars and normal mucosa was 0.5 and 0.49, respectively, showing no significant difference between the two groups. The ultimate Young's modulus of mucosa scars was about 24.22 MPa, however, it declined to 3.32 Mpa in normal mucosa.
CONCLUSIONSThe mucosa scars after cleft palate surgery are biomechanically weaker than normal mucosa. It can be used for further research, such as maxillary orthognathic surgery, distraction osteogenesis, and orthodontic treatment.

Objective To improve the diagnosis and treatment of ureteral cancer. Methods A retrospective analysis of 24 cases of primary ureteral cancer treated from January 1990 to March 2005 was performed.The diagnostic value of ultrasound,IVU,CT,MRU and the patients' outcomes were reviewed. There were 19 males and 5 females aged 38-72 years(mean,59 years).The tumors were on the left side in 16 cases and on the right in 8.Of the 24 cases,17(71%)had gross hematuria and 7(29%)had micro- scopic hematuria.Urine cytology was performed in 16 cases with a positive rate of 6.3%.B-ultrasonic exami- nation showed hydronephrosis in 19 cases(79%)and low-echo space-occupying disease of middle-inferior ureter in 3(12%).IVU demonstrated hydronephrosis in 20 cases(83%)and filling defect of the diseased ureter in 3(12%).Retrograde pyelography showed filling defect of the diseased ureter in 16(76%)of 21 cases(5 cases had failure of intubation).CT scan was performed in 20 cases,indicating thickening of the ureteral wall and infiltration of the cancer in 14(70%).In 3 cases who had undergone spiral CT thin layer scan and 1 of 3 cases who had undergone MRU,the definite diagnosis was made.Results All the 24 pa- tients underwent surgical treatment.Among them,nephroureterectomy and bladder cuff or partial resection were performed in 18 cases,and nephrectomy and partial ureterectomy in 6 cases.Postoperative pathology showed transitional cell carcinoma in 23 cases,and adenoma in 1.Of the 14 cases during 1990-1999 peri- od,1,5,3,2,2 and 1 cases had survival time of 1,2,3,4,5 and 6 years,respectively.Of the 10 cases during 2000-2005 period,3 were lost to follow-up;2 survived for 3 years and 2,for 1 year;the other 3 who have survived near 5 years have been followed till now.Conclusions IVU and retrograde urography are the most common diagnostic measures for primary ureteral cancer.They can be used in combination with other imaging study to reduce missed diagnosis rate.The 5-year survival rate was lower because of late pathologic stage of the tumors in the patients of this series.
