Objective To investigate the correlations between plasma levels of carnitine(CT),free fat acid(FFA) and insulin resisitance in children with simple obesity.Methods Fifty-six children diagnosed with simple obesity were enrolled as study group(obesity group),36 healthy children as control group.The concentration of plasma level of insulin was measured by radioimmunoassay(RIA),CT was measured by high performance liquid chromatography(HPLC),FFA and triglyceride(TG) were measured by enzymatic-colorimetric assay.Body mass index(BMI) and waist to hip ratio(WHR) were caculated.Insulin sensitivity index (InSI) and insulin resistance index (InRI) were cacula-ted by homeostasis model assessment of insulin resistance (HOMA-IR).SPSS 13.0 software was used to analyze the data.Results The concentration of CT in plasma was (43.67?12.75) ?mol/L in obesity group,(58.31?21.25) ?mol/L in control group,respectively.There was a significant difference between 2 groups (t=2.566 P

In order to study the pathogenesis of HPVl1 and seek for a therapeutic approach of the disease caused by HPV1l. The HPVl1/E2 644bp was amplified by PCR with HPVll plasmid DNA. pGEM-T Easy was used as vector and a clone pTV-644 was obtained.The inserted DNA sequencing was carried out after selecting and identification. According to the hammerhead structure described by Symon's, the possible secondery cleavage sites on HPVll/E2 mRNA were analyzed and the secondery structure of substrate was predicted by computer and ribozyme, excluding analogous sequence of substrate combined with ribozyme were found in the mRNA.The hammerhead ribozyme of RZ2777 against HPV1l/E2 mRNA was seleted to carry out cleavage reaction in vitro. Results of the experiment showed that 644bp substrate derived from HPVll/E2 can be cleavaed site-specifically by ribozyme in vitro. The cleavage activity showed over 85% by choosing the optimun reaction condition, which was not affected by two cis-ribozymes on both 3′-and 5′-ends released by self cleavage,but two flan-king sequences of target RNA influenced the cleavage activity. Results demonstrated that the ribozyme will become a highly effective and specific therapy against HPVll infection.

Gastric bronchogenic cysts （GBCs） is uncommon with atypical clinical features. It is difficult to diagnose by preoperative imaging examinations. Therefore , postoperative histopatho-logical examination is regarded as the golden bacteria in ultimate diagnosis. The treatment of GBCs：ultrasound-guided fine needle aspiration and endoscopic mucosal resection is only used for small GBCs with intra-cavity growth pattern. However , GBCs with extra-cavity growth pattern is featured with deeply anatomical position , large size , and prone on attaching to vital blood vessels and organs , which makes laparoscopic resection is the first choice in treatment. The authors introduce the diagnosis and treatment of a case of GBCs attaching to lesser curvature , in order to provide references for clinical diagnosis of GBCs.

Background The tissue-engineered cornea is becoming the hot spot in the ophthalmologic field,while the research of corneal substitute is in the ascendant,because it is more similar to the corneal morpha and easy to survive in vivo.Objective This study was to investigate the biocompatibility of recombinant human type-Ⅲ collagen/poly9 ( 3-( methacryloylamino ) propyl dimethyl ( 3-sulfopropyl ) ammonium hydroxide ) ( PMPDSAH ) interpenetrating polymer network (IPN) (RHC-Ⅲ/PMPDSAH IPN) hydrogel as a tissue-engineered cornea in rabbit eye and its feasibility as the corneal substitute.Methods One hundred and eight rabbits were randomly divided into experimental group( 90 rabbits) and normal control group ( 3 rabbits),and 15 rabbits ( 30 eyes ) used as the donor corneas.RHC-Ⅲ/PMPDSAH IPN,NGF PMPDSAH IPN and corneal grafts were lamellarly transplanted into the right eyes in RHC-Ⅲ/PMPDSAH IPN group,NGF PMPDSAH IPN group and allograft group respectively.The corneal transparency and neovascularization were examined and scored under the slim lamp and compared among three groups using Kraskal-Wallis H test.The corneal epithelization time was observed and compared among these three groups using one way analysis of variance and LSD-t test.The histological examination of corneas was performed at the 3rd day,1st and 2nd week,1 st,3rd and 6th month after the surgery.The immunohistochemistry was used to detect the expression of K3 in cornea at the 6th month.Results The grafts were well attached in RHC-Ⅲ/PMPDSAH IPN group,NGF PMPDSAH IPN group and allograft group,and no rejection reaction was found throughout 6-month following up.Compared with normal control group,no significant differences were found in the scores of corneal opacification and neovescularization in these three groups (x2 =4.34,P =0.23 ;x2 =2.60,P =0.46 ) at the 6th month.NGF PMPDSAH IPN group achieved reepithelialization in (4.97±0.63) days and was obviously shorted than that in RHC-Ⅲ/PMPDSAH IPN group and allograft group ( t =11.97,P =0.00; t =5.80,P =0.00).The re-epithelialization time in RHC-Ⅲ/PMPDSAH IPN was (6.86±0.71) days,and that of allograft group was (5.87±0.43 ) days,showing a significant difference ( t =6.32,P =0.00).Hematoxylin-eosin staining results demonstrated that implanted materials integrated into the host corneal tissue well and support corneal epithelialization.Part of the material degraded at the 2nd week and degraded completely 1 month later.Regular alignment and distribution of collagen fibers were seen in the regenerated cornea and were similar to those of the normal stroma in 6 months.Immunohistochemistry showed the positive expression of keratin-3 in corneal epithelial cells.Conclusions RHC-Ⅲ/PMPDSAH IPN has a good biocompatibility without toxicity to corneal tissue.Furthermore,NGF can promote the corneal wound-healing and re-epithelialization.The material can be used as safe and reliable corneal substitute after improving the mechanical strength.

OBJECTIVETo evaluate the efficacy and safety of Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion for pancreatic cancer with liver metastases (PCLM).

METHODSWe retrospectively selected 292 patients with PCLM who were treated by Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion at Tianjin Medical University Cancer Hospital from January 2001 to December 2010. All patients were assigned to the Western medicine treatment group (157 cases) and the integrative medicine treatment group (135 cases). Patients in the Western medicine treatment group were treated with gemcitabine (GEM)-based chemotherapy, and partial of them received regional arterial perfusion. Those in the integrative medicine treatment group additionally took Chinese herbs of clearing heat and eliminating mass for at least 4 weeks. The median survival time (MST) , adverse reactions and the incidence of complications were observed.

RESULTSThere was no statistical significance in general data between the two groups (P > 0.05). There was statistical difference in MST between the two groups (4.8 months vs 5.5 months, P < 0.05). No death occurred during chemotherapy or regional arterial perfusion. All toxic or adverse reactions were tolerable.

CONCLUSIONChinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion was effective and safe, and it could be optimally selected as palliative therapy for PCLM.

Objective To investigate the potential relationship between initial 131Ⅰ uptake by lung metastases from differentiated thyroid cancer (DTC) and treatment outcomes. Methods From 1997 to 2009, 41 patients with DTC lung metastases were treated in the authors' department. 131Ⅰ whole body scan (WBS), serum Tg levels and other imaging results were analyzed to evaluate the therapeutic effects. Complete response (CR) or partial response (PR) was considered to be effective. The x2 test and correlation analysis were performed using SPSS 11.5 software package. Results 131 Ⅰ treatment was effective in 63% (26/41) patients with DTC lung metastases, CR in 8 patients and PR in 18 patients. In other 37% ( 15/41 ) patients, 131Ⅰ treatment was ineffective, including one case died of distant metastases. Patients with initial presence of 131Ⅰ lung uptake had higher effective rate than those with 131Ⅰ lung uptake during the second or later 131Ⅰ treatment (76% (22/29)vs33% (4/12),x2 =4.911, P=0.027). Also, significantly higher effective rate was found in patients with lung metastases alone than those with extra-pulmonary metastases (75% (24/32) vs 22% (2/9), x2 = 6. 312, P =0.012). However, the effective rate in patients with diffuse metastases was not significantly different from that in patients with focal metastases (67% (12/18)vs 61% ( 14/23), x2 =0. 146, P=0.702). The positive rate of initial 131Ⅰ uptake by lung metastases was higher in patients with total thyroidectomy than those with partial thyroidectomy (83% (24/29) vs 42% (5/12) ). Those positive rates in patients with papilary DTC and patients with follicular DTC were 72% (23/32) and 6/9, respectively. The surgical mode was correlated with the initial 131Ⅰ uptake by lung metastases (r = 0.411, P ＜ 0.05), but no correlation was found between the histological type and the initial 131Ⅰ uptake by lung metastases ( r = 0. 047, P ＞ 0.05 ). Conclusion Initial uptake of 131 Ⅰ by lung metastases alone is a favorable prognostic factor for DTC patients treated by131Ⅰ, and total thyroidectomy may be beneficial for initial 131Ⅰ uptake by lung metastases.
