Objective To explore the variation about the application of fast-track surgery and laparoscopy in treatment for colorectal cancer in recent years.To investigate the probability of combining protocols of the two for treatment for colorectal cancer.Methods The clinical and basic literatures of related researches about colorectal treatment of laparoscopy and fast-track surgery were collected and reviewed.Results Compared with the traditional treatment modalities,both of fast-track surgery and laparoscopy used for the treatment of colorectal cancer have better clinical effects.Conclusions Fast-track surgery and laparoscopic techniques used for the treatment of colorectal cancer are feasible,but the combination of the two should be confirmed by further randomized controlled trials.

Objective Toexploretheclinicalefficacyandtoxicityofintensitymodulatedradiationtherapy(IMRT)combined with high intensity focused ultrasound(HIFU) for inoperatable recurrent hepatic carcinoma after operation and TACE .Methods Total 60 patients with inoperatable recurrent hepatic carcinoma after operation and TACE were randomly divided into two group ,30 patients in observation group received IMRT and HIFU ,while 30 patients in control group received only IMRT .For both groups , the same radiotherapy technic was given with IMRT in 6 MV X‐ray ,the total dose was 54 -70 Gy/6 -7 weeks .In observation group ,HIFU was carried out concurrently with IMRT (5 days/week ,6-7 weeks) .Results The difference of the short‐term effi‐cacy between the observation group and the control group was statistically significant (P<0 .05) ,there was no significant difference in acute radioactive toxicity between the two groups (P>0 .05) .The one and two year overall survival rate 89 .9% ,78 .9% in obser‐vation group ,while 72 .8% ,36 .2% in control group ,the differnces were statistically significant (P<0 .05);the one and two year progression‐free survival rate were 85 .9% and 50 .9% in observation group ,while 64 .3% and 28 .1% in control group ,the differ‐ences between two groups were statistically significant (P<0 .05) .The medium survival time was 36 months in observation group , and 24 months in control group;the medium progression‐free survival was 27 months in observation group ,and 17 months in control group .Conclusion For recurrent unresectable or reject surgery after TACE in patients with primary hepatic carcinoma ,the efficacy of IMRT combined with HIFU treatment is effective ,the toxicity can be tolerated ,and has certain application value .

Objective To investigate the xenotransplantation model of fetal pig skin precursor tissue and its development after transplantaion. Methods Porcine skin precursor tissue was obtained from the embryo of gestation day 56 (E56), and made into microskin or stamp skin graft. The microskin was transplanted to the dorsal wound in BALB/c nude mice, then covered with human corpse skin. The stamp skin graft was imbedded subcutaneously into the back of nude mice, and microskin was injected subcutaneously into the auricles of nude mice. Their growth and development were observed and they were examined by HE staining at 6th and 12th week after transplantation respectively. Two-sample t test was used to analyze the size of newly grown skin tissue. Results Porcine skin precursor tissue graft in three models above survived and continued growth after transplantation, and growth ability of the dorsal wound transplantation model was significantly stronger than that of the auricle model. Epidermis and hypodermis were detected in newly grown skin tissues. Hair follicles, a few of sebaceous glands, but no sweat glands were observed in auricle model, while many sebaceous glands and sweat glands were observed in the dorsal wound model. Conclusion Transplantation of microskin to dorsal wound is the optimal model of investigating the xenotransplantation of fetal pig skin precursor tissue and its development after transplantion.

Objective Non-invasive detection is the focus of intense research in diagnosis of acute renal allograft rejection currently. Urine protein is considered the cue to reflect the pathological changes in kidney disease. In this study, we explored the urine markers for early acute renal allograft rejection. Methods The urine protein of two patients with acute renal allograft rejection were examined by 2D gel electrophoresis and bioinformatics. We adopted pH 4-7 ready strip IPG and stained the gel with Sypro-Ruby. The digitized 2D maps of urine protein were quantitatively analyzed using 2D-analysis software packages. By analyzing the differential expressions of proteome between different time points (1, 2, 3 days before acute rejection and 7, 14, 21 days after acute rejection), 30 protein spots were selected and analyzed by MALDI-TOF-MS/MS. Results We obtained 2D gel electrophoresis maps of urine protein of the patients with acute renal allograft rejection, which are of good reproducibility and resolution. Sixteen protein spots were identified, resulting in thirteen corresponding proteins. Out of these proteins, we screened three proteins (alpha-1-antichymotrypsin, tumor rejection antigen gp96, Zn-Alpha-2-Glycoprotein) closely related to acute rejection. Conclusion The urine protein spots on 2D gel electrophoresis maps for the patients with acute renal allograft rejection were of obvious difference when detected at different time points of acute rejection. Alpha-1-antichymotrypsin, tumor rejection antigen gp96 and Zn-Alpha-2-Glycoprotein might be the candidate protein markers to diagnose acute renal allograft rejection after renal transplantation.

A 7-year-old female patient presented with frontal bossing and exophthalmos complicated by skin pigmentation all over the body for 7 years.Pigmentation was seen on the flexor aspects of the bilateral elbows 1 week after birth,and skin pigmentation gradually appeared at multiple body sites 1 year later.She had suffered from lacrimal duct obstruction since childhood,and repeated dredging of the duct was ineffective.Parents of the child were healthy and non-consanguineous marriage,and had no family history of the same disease.Physical examination showed square-shaped skull,frontal bossing,maxillary hypoplasia,mandibular prognathism,exophthalmos,ocular hypertelorism,depressed nasal bridge,dental malocclusion,and irregular dentition.Skin examination showed dark brown skin all over the body,coarse skin on the neck,axillary and inguinal regions,papillomatous cutaneous thickening,with velvet-like appearance.The patient was diagnosed with Crouzon syndrome complicated by acanthosis nigricans (CAN).Polymerase chain reaction (PCR)and DNA sequencing were performed to detect mutations in the FGFR3 gene in the patient with CAN,her parents and 100 unrelated healthy controls.A heterozygous missense mutation (C.1172 C ＞ A) was identified in the FGFR3 gene in the proband,but not in her parents or the 100 unrelated healthy controls.The missense mutation in the FGFR3 gene may be a causative mutation leading to the clinical manifestations of the patient.

OBJECTIVETo investigate the effects of baicalin against Candida glabrata, C. parapsilosis, C. krusei and C. guilliermondii biofilms.

METHOD96-well microtitre plates were used to set up the biofilms; microdilution method was applied to detect minimal inhibitory concentration (MIC) of baicalin for the four non-albians Candida, and XTT reduction assay was adopted to determine sessile minimal inhibitory concentration (SMIC) of baicalin against the four isolates and to detect the effects on adhesion of the fungal cells.

RESULTMICs of baicalin for the four non-albians Candida cells were 125, 250, 125, 62.5 mg L(-1), respectively. The four non-albians Candida could form mature biofilms on 96-well microtitre plates. SMIC50 of baicalin for the four isolates were > 1000, 500, 125, 250 mg x L(-1), respectively. SMIC80 for the four isolates were greater than or equal to 1000 mg x L(-1). Baicalin showed potent inhibitory effects on adhesion of the four non-albians Candida cells.

CONCLUSIONBaicalin displays substantial inhibitory effects on C. parapsilosis, C. krusei and C. guilliermondii biofilm.
