BACKGROUND: It has been reported that chitosan can inhibit scar formation and promote wound healing. Medical invisible antimicrobial film is a new type of membrane materials which comprises chitosan as ground substance.OBJECTIVE: To determine the inhibitory effects of medical invisible antimicrobial film on the operative incision scar, and to observe its effects on wound healing.DESIGN, TIME AND SETTING: A controlled animal study was conducted at the IVC Experimental Animal Room, West China School of Pharmacy, Sichuan University from August to October 2007.MATERIALS: Medical invisible antimicrobial film stock solution was colorless transparent sticking solution, which formed colorless transparent film following spray painting (specification: 40 mL), provided by Chengdu Chaojl Technology Co., Ltd. (lot number 070501).METHODS: A total of 16 healthy Sprague Dawley rats aged 20 to 23 days were selected. Full linear skin incisions were operated in aseptic condition. After operation, the experimental group (right side) was sprayed medical invisible antimicrobial film 0.5 mL/time, once a day, for totally 3 days. The control group (left side) received an equal volume of 0.9% sodium chloride injection, with natural cure.MAIN OUTCOME MEASURES: At 3, 7 and 14 days following surgery, incision skin specimens were obtained, and subjected to hematoxylin-eosin staining and Masson staining was applied to observe wound healing and the formation of scar, then the scar area was analyzed.RESULTS: The scar relative mean area of control group was 154 069±51 356 and the experimental group was 98 200±34 719 on the postoperative 14~(th) day. The two groups were significantly different (P < 0.05). At 14 days following surgery, optical microscope showed that the experiment group had less collagen fibers and fibroblast accumulation. At 3 days, compared with the control group, the experimental group had less epithelization period, more granulation tissue and less inflammatory cell infiltration.CONCLUSION: The medical invisible antimicrobial film has inhibitory effect of the formation of operative incision scar, and no influence on wound healing of operative incision.

AIM:To investigate the expression of up-regulated gene 11 ( URG11 ) in prostate cancer cell line and the effect of URG11 siNRA on the proliferation and invasion of human prostate cancer LNCaP cells.METHODS:The mRNA and protein levels of URG11 in prostate cancer cell lines and normal prostate epithelial cell line were evaluated by real-time PCR and Western blot.LNCaP cells were transfected with designed siRNA using the liposome method.The prolif-eration, apoptosis, migration and invasion abilities of the LNCaP cells were evaluated by MTS assay, flow cytometry, wound-healing assay and Transwell assay.RESULTS:The expression of URG11 at mRNA and protein levels in the DU145, PC3, LNCaP cell lines was significantly higher than that in RWPE-1 cell line.Compared with the control group, the proliferation of LNCaP cells with URG11 siRNA was stagnant in G1/S phase and induced apoptosis.The proliferation of LNCaP cells at 0 h, 24 h, 48 h and 72 h was inhibited after URG11 expression was down-regulated (P<0.05).Transwell assay showed that migration (P<0.05) and invasion (P<0.05) were also inhibited.CONCLUSION:URG11 is highly expressed in prostate cancer.Silencing of URG11 significantly inhibits the proliferation and invasion and induces apoptosis of LNCaP cells.

Objective To analyze the rule of lymph node metastasis in thoracic esophageal carcinoma,and to study the proper radiation target. Methods From September 1986 to December 1997,549 patients with esophageal carcinoma who had undergone radical reseetion were divided into surgery alone group (S,275 patients) or surgery plus radiotherapy group( S + R,274 patients). Radiotherapy was begun 3 to 4 weeks after operation. The radiation target included beth supra-clavicular areas and the entire mediastinum. The total dose was 50 Gy in 25 fractions over 5 weeks for the supra-clavicular areas and 60 Gy in 30 fractions over 6 weeks for the entire mediastinum. Results The 5-year overall survival of patients with lymph node metastasis in one anatomic site and two anatomic sites was 31.5% and 13.9% (P=0.013), respectively. For patients with > 2 positive nodes metastasis receiving surgery alone, the corresponding 5-year survival was 24.8% and 4.9% (P=0.046) ,respectively. The median number of dissected lymph nodes of the upper-,middle-and lower-segment esophageal carcinoma was 13,17 and 20, respectively. The rate of metastatic lymph node in the para-esophagus region was the highest(61.5%-64.9%) ,which was not different among the different primary sites(P=0.922). The anastomotic stoma recurrence rate of the upper-segment esophageal carcinoma was higher than that of the middle- or lower-segment carcinomas(16.7% ,3.1% ,and 7.7%, χ2=9.02,P<0.05). Conclusions For the thoracic esophageal carcinoma,the number of anatomic sites of lymph node metastasis is an important factor affecting the survival. The lower rate of lymph node metastasis of the upper segment esophageal carcinoma may be corrected with the less lymph node dissected. The rate of lymph node metastasis in para-esophageal region is not related with the lesion segment. The anastemotie stoma is an important radiotherapy target for upper segment esophageal carcinoma.

Objective To compare the clinical outcomes between conventional percutaneous vertebroplasty (PVP) and targeted PVP in the treatment of osteoporotic vertebral compression fractures (OVCFs).Methods A retrospective cohort study was designed to review 215 cases of single level OVCFs hospitalized between January 2014 and December 2015.According to the procedure techniques,the patients were assigned to targeted PVP group (89 cases) and conventional PVP group (126 cases) which was further divided into sufficient filled subgroup (110 cases) and insufficient filled subgroup (16 cases) on basis of cement distribution.Key techniques of targeted PVP included accurate needle insertion to fractured area and cement injection using a push rob with a side opening.Operating time,cement injection volume,rate and types of cement leakage,cement distribution in the fractured area and visual analogue score (VAS) of back pain were compared between the two groups.Results Operating time in targeted PVP group was longer than that in conventional PVP group (P ＜ 0.05).There were no significant differences in cement injection volume and rate and types of cement leakage between the two groups (P ＞ 0.05).None in targeted PVP group showed insufficient cement distribution in fractured area,while 16 cases (12.7％) in conventional PVP group (P ＜ 0.05).No significant differences in preoperative VAS of back pain existed among targeted PVP group,sufficient subgroup and insufficient subgroup (P ＞ 0.05).VAS of back pain was significantly decreased after PVP in three groups (P ＜ 0.05).Difference in postoperative VAS of back pain between targeted PVP group and sufficient filled subgroup was insignificant (P ＞0.05).However,postoperative VAS of back pain in insufficient filled subgroup was significantly increased compared with targeted PVP group and sufficient filled subgroup (P ＜ 0.05).Conclusion Targeted PVP provides sufficient cement to fill the fractured area and decreases incidence of unsatisfactory clinical outcome compared with traditional PVP,indicating a secure and effective new technique in the treatment of OVCFs.
