Objective To investigate the relationship between truncating mutations of APC gene and sporadic colorectal cancer,and analyze the feasibility of non-radioactive protein truncation test (PTT) in the detection of mutations of APC gene.Methods Ninety-six samples of sporadic colorectal cancer tissues ( including 44 patients with colonic cancer and 52 patients with rectal cancer) were obtained from the General Hospital of Ningxia Medical University from September 2008 to September 2010.The mutation cluster region of the APC gene was screened using digital PTT labeled with fluorescent Lys-t-RNA,with a polymerase chain reaction fragment amplified from genomic DNA serving as a tenplate for in vitro translation.The occurrence of gene mutation was determined according to the emergence of truncated peptides.The mutation cluster region of the APC gene in 46 samples of colorectal cancer tissues was analyzed by direct sequencing.The detection rates of the 2 methods were compared by chi-square test.Results Thirteen (26％) truncated peptides were detected in the 50 samples of colorectal cancer tissues.The mutation type of 4 samples is nonsense mutation,which resulted in emergence of truncated gene products.Eleven (24％) truncated peptides were detected in the 46 samples of colorectal cancer tissues.There was no significant difference in the detection rates between PTT and direct sequencing ( x2 =0.033,P ＞ 0.05 ).Conclusions Truncating mutations of APC gene are common alterations in sporadic colorectal cancer in the Chinese.Digital PTT labeled with fluorescent Lys-t-RNA is rapid and high-sensitive in screening gene mutations.

Objective To investigate the prevalence features of helicobacter pylori (Hp) infection,anemia and iron deficiency in a po-pulation of Wuhan children with 2 to 6 years old,and the relationship between Hp infection and anemia,iron deficiency in the children.Methods Randomly taking 95 children who had taken tests in our hospital's check-up centre in 2008 as the study objects,2 kinds of exa-mination were employed to detect Hp infection.Serum levels of Hp-IgG were measured by enzyme linked immunosorbent assay (ELISA) methods to evaluate past infection.The 14C urea breath test (14C-UBT) was conducted to obtain information of the presence of current/active Hp infection.In the morning 3 mL fasting venous blood was collected to determine the serum levels of Hp-IgG antibodies and ferritin.Hemoglobin values were determined with a hemoglobinometer.Serum levels of C-reactive protein (CRP) were tested in order to determine whether the children had evidence of current inflammation or infection.In addition,demographic information such as age and gender of the children and information about their use of antibiotics within the prior month were recorded.All cases were divided into 2 groups including the Hp infection group and non-Hp infection group according to laboratory examinations,then the Logistic regression was applied to analyze the relationship between Hp infection and anemia,iron deficiency.The Kappa identity test was taked to compare the 2 measures.Results Of the 95 children,18.9% were anemic and 36.8% were iron deficient.Forty percent of the cohort had Hp-IgG antibodies,74.4% tested positive by the UBT.Presence of Hp-IgG emerged as a significant risk factor for anemia,iron deficiency in adjusted analysis controlling for demographic factors,current inflammation,and antibiotic use.Conclusions Findings from different measure of Hp may reflect different stages of infection,with UBT results reflecting an earlier stage of infection,and presence of Hp-IgG reflecting established Hp infection associated with anemia,iron deficiency.

OBJECTIVETo evaluate the histopathological characteristics and clinical implication of sarcolemma tissue in prepubertal concealed penis.

METHODSAfter measurement of the penile length, 10 prepubertal children with congenital concealed penis underwent modified Devine's operation (treatment group), and another 10 normal prepubertal children received circumcision (control group). The anatomic features of the penile sarcolemma tissue was observed intraoperatively, and its fibrosis was evaluated by Masson trichrome staining.

RESULTSThe penile length of the treatment group was significantly shorter than that of the control group preoperatively ([1.49 +/- 0.17 ] cm vs [4.26 +/- 0.23 ] cm, P < 0.01). The degree of penile concealment was correlated with the distal point of the attachment of its sarcolemma fibrous tissue: the closer the distal attachment point was to the coronary ditch, the more serious was penile concealment. The proportion of the area of collagen fibers in the penile sarcolemma tissue was significantly higher in the treatment group than in the control ([65.6 +/- 6.9]% vs [37.1 +/- 4.7]%, P < 0.01).

CONCLUSIONSarcolemma fibrosis was obvious in congenital concealed penis, and the key to its management is drastic removal of all the fibrous sarcolemma tissue.

Aim The effect of tetrandrine on TGF-?1 mRNA expression in glomerulosclerosis rat was observed. Methods The rats were randomly divided into four groups, such as the normal control group (sham operative rat), glomerulosclerosis model group,tetrandrine group and amlodipine group. The expression of TGF-?1 mRNA was analyzed by Northern blot hybridization. Results The expressions of TGF-?1 mRNA in two treating groups were much lower than untreated model group. There were no difference between these two treating groups. Conclusion Tetrandrine can decrease the expression of TGF-?1 mRNA in glomerulosclerosis rat induced by unilateral renctomy plus adriamycin.

ObjectiveTo evaluate the protective effect of Xuebijing injection against renal injury in patients with sepsis, and to explore its possible mechanism.Methods A prospective randomized controlled trial (RCT) was conducted in which 62 severe patients with sepsis and septic shock admitted in Department of Critical Care Medicine of Jiangsu Province Traditional Chinese Medicine Hospital from June 2013 to December 2013 were randomly divided into control group and Xuebijing group, with 31 patients in each group. The patients in both groups received basic treatment for sepsis, and the patients in Xuebijing group were additionally given intravenous injection of Xuebijing 100 mL once a day for 7 days. In both groups, the changes in acute physiology and chronic health evaluationⅡ (APACHEⅡ) score were observed before treatment and 1, 3, 7 days after treatment, and the changes in the levels of interleukins (IL-6, IL-10), prothrombin time (PT), fibrinogen (Fib), activated partial thromboplastin time (APTT), serum creatinine (SCr), and Cystain C (Cys C) were determined before treatment and 1 day and 3 days after treatment.Results There was no statistically significant difference in APACHEⅡ score before treatment between two groups, however, the APACHEⅡ scores were significantly decreased in both groups 3 days and 7 days after treatment compared with those before treatment, and the degree of decrease in Xuebijing group was more obvious 7 days after treatment (13.61±7.62 vs. 16.34±8.70,P< 0.05). Serum concentrations of Cys C, SCr, IL-6, IL-10, PT, APTT, and Fib showed no difference between two groups before treatment (allP> 0.05), while after treatment the degrees of improvement of above indexes in Xuebijing group were obviously superior to those in control group, especially 3 days after treatment[Cys C (mg/L):1.12±0.11 vs. 1.35±0.14, SCr (μmol/L): 115.0±31.0 vs. 135.0±24.0, IL-6 (ng/L): 54.27±28.79 vs. 73.35±31.01,PT (s): 13.50±0.11 vs. 15.71±0.11, APTT (s): 43.66±0.31 vs. 48.03±0.55, Fib (g/L): 1.91±0.51 vs. 1.51±0.52, P< 0.05 orP< 0.01].ConclusionXuebijing injection has certain renal protective effect in patients with sepsis, and its mechanism is possibly related to the regulation and improvement of uncontrolled inflammatory response and coagulation function in sepsis.

AIM: To investigate the time - effect relationship between the expression of rhodopsin and recoverin and photoreceptor damage induced by N - nethl - N -nitrosourea ( MNU) .
METHODS: Thirty-six 7-week old Sprague-Dawley ( SD ) rats were intraperitoneally injected with MNU ( 60mg/kg ) and were put to death by dislocation of cervical vertebra 6, 12, 24h; 3, 7d after injection ( 6 per group) , respectively. As a control, six rats were injected with phosphate buffer saline (PBS) 5mL/kg and sacrificed on d3 after injection. The degree of photoreceptor apoptosis was detected by HE staining, terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling ( TUNEL ) and transmission electron microscope ( TEM ) in the right eyes. The mRNA expressions of rhodopsin and recoverin were detected different time after injection by Western blot and immunohistochemical method in the left eyes.
RESULTS:The dissolution of photoreceptor nucleus and apoptosis body were first perceived at 12h by TEM; most of cells at outer nuclear layer were presented positive reaction. The apoptotic index reached peak ( 29. 7% ±2.3%) at 24h which was coincided with the observation of TEM. The results of immunohistochemistry displayed that rhodopsin and recoverin were on a declining curve with time extension. Furthermore, the results of Western blot indicated that rhodopsin had dramatic decline at 6h after injection (P<0. 05), and extremely significant difference comparing to control group after 12h ( P<0. 01 ); while recoverin dramatic declined at 12h, and extremely significant difference after 24h (P<0. 01).
CONCLUSION:60mg/kg MNU intraperitoneally injection one - time may specifically induce photoreceptor apoptosis, The mechanism of down - regulation of rhodopsin and recoverin may be related to the selected apoptosis of photoreceptors.

Objective To discuss the diagnosis and surgical treatment for carotid body tumors (CBT). Methods Retrospective analysis was made on 16 cases of carotid body tumors hospitalized in Shandong Provincal Hospital from January 2003 to October 2010. All patients were diagnosed by digital subtraction angiography, including 3 case of Shamblin type Ⅰ,11 cases of Shamblin type Ⅱ and 2 cases of Shamblin type Ⅲ. Three cases of type Ⅰ and 3 cases of type Ⅱ underwent carotid body tumor resection. Three cases of type Ⅱ underwent carotid body tumor plus external carotid artery resection, 3 cases underwent carotid body tumor plus external carotid artery resection plus carotid artery repairment, 2 cases did carotid body tumor plus external carotid artery resection plus internal carotid artery reconstruction. One of type Ⅲ underwent carotid body tumor plus external carotid artery resection plus carotid artery repairment, and the other one underwent carotid body tumor plus external carotid artery resection plus internal carotid artery reconstruction. Results Diagnosis of CBT was confirmed by pathology in all cases. There was no postoperative death、hemiplegia and blindness. The cranial nerve injury was caused in 7 cases, accounting for 43. 75%. 13 cases ( 81. 25% ) were followed up for 2 to 76 months ( mean 42 months), no tumor recurrence and metastasis was found. Conclusions Digital subtraction angiography (DSA) is important in the diagnosis and therapy of carotid body tumor. Surgical treatment is the choice of therapy for carotid body tumors.

We reviewed the clinical data of 24 patients with postpartum hemorrhage undergoing transcatheter arterial embolism from March 2009 to September 2011.Twenty out of 24 patients underwent uterine artery embolism,while other 4 underwent internal iliac artery embolism.The hemorrhage reduced markedly 2 to 9 min after arterial embolism in all patients,except 2 who underwent secondary embolism due to the intermittent postoperative hemorrhage. The postoperative complications included low fever and discomfort in lower abdomen.Nineteen patients were followed up for a mean period of ( 17.3 ± 1.1 ) months,no recurrent hemorrhage was observed after discharge.The normal menstrual cycle recovered 4 to 6 months after operation.Three patients underwent pregnancy successfully after discharge.The results indicate that transcatheter arterial embolism is safe and effective in the treatment of postpartum hemorrhage and it should be recommended as a feasible choice in clinical practice.
