Objective To review the surgical managements of patients with traumatic false aneu- rysms in the extremities.Methods From January 1990 to April 2006,17 patients with traumatic false aneurysms in the extremities were admitted into our hospital.Fourteen patients were treated by vascular repair including vascular repair in seven cases,end to end anastomosis in one,synthetic grafting in one, autogenous vein grafting in one,and direct ligation in four.Three patients were treated nonoperatively, but with local compressive dressing.Results There were no deaths or gangrenes in all cases.The clinical manifestations vanished after the treatment.The mean follow-up period was 13.2 months.The function of the injured extremities recovered satisfactorily.Conclusion Different types of traumatic false aneurysms should be managed by different therapeutic procedures after the diagnoses is made.

OBJECTIVETo evaluate the erectile and ejaculatory function of sacral tumor patients after sacral nerve root resection and investigate the relationship of erectile and ejaculatory dysfunction (EED) with the level of sacral nerve injury.

METHODSThis retrospective study included 47 male patients aged 16 to 63 (32.6 +/- 6.8) years treated by sacral tumor resection between January 2008 and August 2013. According to the levels of the sacral nerve roots spared in surgery, the patients were divided into four groups: bilateral S1-S3 (n=16), unilateral S1-S3 (n=21), unilateral S1-S2 (n=6), and unilateral S1 (n=4). The patients were followed up for 12 to 41 (27.2 +/- 10.9) months by questionnaire investigation, clinic review, and telephone calls about their erectile and ejaculatory function at 3, 6 and 12 months after surgery and in August 2013.

RESULTSIn the bilateral S1-S3 group, the incidence rates of EED were 31.25% (5/16), 25% (4/16), and 12.5% (2/16) at 3, 6, and 12 months respectively after surgery, with recovery of erectile and ejaculatory function in August 2013. The incidence rates of EED in the unilateral S1-S3 group were 85.71% (18/21), 71.43% (15/21), 52.38% (11/21), and 42.86% (9/21) at 3, 6 and 12 months and in August 2013, respectively; those in the unilateral S1-S2 group were 100% (6/6), 83.33% (5/6), 83.33% (5/6), and 66.67% (4/6) at the four time points; and those in the unilateral S1 group were all 100% (4/4). No statistically significant differences were found in the incidence rate of EED among the patients of different ages or tumor types (P > 0.05).

CONCLUSIONThe incidence of postoperative EED in male patients treated by sacral tumor resection is closely related to the mode of operation. Sparing the S3 nerve root at least unilaterally in sacral tumor resection is essential for protecting the erectile and ejaculatory function of the patient.

To study the compatible mechanisms and compatible proportion of Shaoyao Gancao decoction, the intestinal absorption of main ingredients in Shaoyao Gancao decoction SG11 (Baishao-Zhigancao 1: 1) , SG31 (Baishao-Zhigancao 3: 1), Baishao water decoction S and Zhigancao (G) were investigated and compared using in vitro everted intestinal sac model and in situ single pass intestinal perfusion (SPIP) model. The concentration of paeoniflorin (PF), liquiritin (LQ) and mono-ammonium glycyrrhizinate (GL) in test samples and samples of intestinal sac and intestinal perfusion was determined by HPLC. The intestinal absorptive amount and absorption parameters were calculated. Results showed that in the everted intestinal sac model, three ingredients could be absorbed by duodenum, jejunum and ileum, and the absorption in the jejunum was best for all 3 ingredients. The absorption rate of three ingredients in SG11 was significantly higher than that in single decoction (P < 0.05), but had no significant difference compared with SG31. In SPIP model, the absorption rate constant K(a), the apparent absorption coefficient P(app) and the absorption rate of three ingredients in SG11 were significantly higher than those in single decoction. Parameters of PF and GL in SG11 were significantly higher than those in SG31, but had no differences of LQ. It proved that the compatibility of Baishao and Zhigancao could improve the intestinal absorption of PF, LQ and GL. The absorption of each ingredient in SG11 was better than that in SG31.

ObjectiveTo evaluate the effect and safety of different thrombolytic therapies for acute cerebral infarction due to occlusion of middle cerebral artery(MCA).MethodsOne hundred and thirty-two cases of acute cerebral infarction in territory of MCA were randomly divided into 3 groups,all of which were treated with alteplase.Group A (48 cases) was treated by intra-venous therapy with alteplase,group B (43 cases) was treated by infusing alteplase at the site of the internal carotid artery,and group C(41 cases) was treated by infusing alteplase into the thrombus.The improvement of neurological function,complications and mortality rate were recorded and statistically compared,with analysis of variance for counting data of normal distribution,x2 test for quantitative data,and the mean difference was significant at the 0.05level.ResultsThe effective rates of group A,B and C at 2 h,24 h,2 w were 18.8％ (9/48),39.6％ ( 19/48),45.8％ (22/48) ;39.5％ (17/43),53.5％ (23/43),58.1％ (25/43) ;78.0％ (32/41),85.4％ (35/41 ),87.8％ (36/41)respectively.The effective rate of group C was obviously better than group A( x2 =12.809,9.979,9.289,P ＜ 0.01 ) and B (x2 =31.295,19.425,17.161,P ＜ 0.01 ) with statistical significance.The effective rate of group B was better than group A at 2 h after thrombolytic therapy with statistical significance (x2 =4.801,P ＜ 0.05 ).The effective rate of group A and B did not have significant difference at 24 h,2 w after therapy ( x2 =1.765,1.375,P ＞ 0.05 ).The hemorrhage rates of group A,B and C were 14.6％ (7/48),14.0％ (6/43),7.3％ (3/41 ),the mortality rates of group A,B and C were 6.2％ (3/48),4.6％ (2/43),2.4％ (1/41),and there was no significant difference among the 3 groups ( x2 =1.328,0.786,P ＞ 0.05 ).ConclusionIt is suggested that the thrombus-imbeded thrombolytic therapy is a better way in treating acute cerebral infraction due to occlusion of MCA for its rapid and better therapeutic effect.

Objective To investigate the state of drinking water defluorination project in Dagang district and study urinary fluoride levels and detect dental fluorosis of children aged 8 to 12, and to provide scientific basis for prevention and control of fluorosis. Methods Five defluorination projects in rural streets (towns) with highfluoride water and 2 urban water supply projects were choosen to investigate the running status in Dagang district Tianjin in 2009. Five rural and 2 urban schools were choosen to select 100 children aged 8 to 12 (for gender, age matched) in each primary school to study urinary fluoride levels and detection of dental fluorosis. Results A total of 66 defluorination projects in 73 villages were surveyed, among which 61 projects actually worked normally with using rate 92.4%(61/66). Water qualification of all projects could not be ensured due to direct project managers'lack of necessary expertise. In 2009, water qualification rate were 39.3%(24/61 )among the project normally used,with highlighted problem of biological pollution. A total of 490 children aged 8 - 12 in 5 rural towns were surveyed,dental fluorosis rate were 90%(441/490), and dental fluorosis index were 1.82. A total of 207 children aged 8 - 12in 2 urban areas were surveyed, the detection rate of dental fluorosis was 49.8%(103/207), and dental fluorosis index were 0.86. The urinary fluoride level of 230 children aged 8 - 12 in the 5 villages were surveyed. The Range of geometric mean of urinary fluoride were 1.82 - 2.70 mg/L. The urinary fluoride of 102 children aged 8 - 12 in the 2 urban area were surveyed. The Range of geometric mean of urinary fluoride were 1.53 - 1.72 mg/L. Conclusions There was phenomenon of high coverage, low utilization rate and less water consumption in the villages of Dagang district, Tianjin drinking water defluoridation projects, thus the health effects of the projects was minimum.Significant health effects is found in the defluorination projects in the urban areas with high coverage and high utilization rate. Studying new water improvment methods and new forms of water supply system is urgent for solving the problems met in the ineffective water defluorination project.

OBJECTIVETo observe the effect of Huxin Formula on expressions of the chief reverse cholesterol transport (RCT) associated genes, caveolin-1 and scavenger receptor-BI (SR-BI) in ApoE-gene knockout [ApoE (-/-)] mice.

METHODSThirty ApoE (-/-) mice of 4-6 weeks old were randomly divided into three groups (A-C). After being fed with high-fat diet for 16 weeks, they were treated with HXF (1 mL/100 g), pravachol (0.3 mg/100 g), and saline in equal volume respectively for 16 weeks successively; in addition, a blank group was set up with 10 C57BL/6J mice of 6-week old received 16-week high-fat feeding and saline treatment. Animals were sacrificed at the termination of the experiment, their paraffin sections of aortic tissue were used to measure the size of plaque, expressions of cavolin-1 and SR-BI were detected by immunological histochemical method.

RESULTSAs compared with the blank group, levels of caveolin-1 and SR-BI were increased in Groups A and B (P<0.01); but the increase in Group A was more significant than that in Group B (P<0.05). The plaque/aorta area ratio decreased significantly in Groups A and B, but showed insignificant difference between the two groups.

CONCLUSIONHXF could obviously increase the expressions of RCT associated genes, caveolin-1 and SR-BI, promote the RCT process, so as to reduce the formation of aorta atherosclerotic plaque in ApoE (-/-) mice.

OBJECTIVETo understand the current situations of saturnism and blood lead levels of children resided in village and circumjacent areas, and to know its relations with sex, age and other factors on children' s health as to providing some evidences for prevention and control.

METHODSAn epidemiological survey was conducted for finding out the pollution sources and for a better understanding of the surrounding environment. All 221 children under 14 years old, from the lead pollution villages and surrounding establishments were enrolled, and their blood lead levels were detected by graphite atomizer absorption spectrophotometer method. Symptoms of the saturnism were investigated through a standardized questionnaire. SPSS13.0 software was administrated for data analysis.

RESULTSHigh blood lead level identification rate was 66.06% (146/221), and saturnism rate 32.13% (71/221). The children's blood lead levels among group 1, group 2, group 3 in this village and jade factory were (161.20 +/- 32.94), (176.60 +/- 43.62), (258.00 +/-106.08) and (238.01 +/- 55.20) microg/L respectively and the significant differences were observed through Kruskal-Wallis test (chi2 = 51.84, df= 3, P<0. 01). The blood lead levels of children from group 3 in this village and the jade factory were higher than those of other two groups. No correlation was found between children's age and blood lead level (r = 0.10, P = 0.13). There was a significant difference in blood lead levels between boys and girls (t' = 3.83, P<0.01). With the children's blood lead levels rising, the occurrence rate of main saturnism symptoms was significantly increased. This survey suggested that the pollution source was a coarse lead smelter.

CONCLUSIONThe blood lead level should ke overwhelmingly increased among children who live nearby the higher level of lead blood, that living nearby the lead smeltery,might result in stautnism and negative effect on children's healthy.

OBJECTIVECleidocranial dysplasia (CCD) is a dominantly inherited skeletal dysplasia caused by mutations in the osteoblast-specific transcription factor-encoding gene, core binding factor α1 (CBFA1). Over 90 mutations in CBFA1 gene have been published to date in 500 independent cases of CCD, including missense mutations, deletions, insertions, frameshift, and splice mutations. However, mutational screening of the CBFA1 gene is still far from saturation, and more novel mutations will be identified to enrich the insights into the molecular basis for the pathogenesis of CCD. The aim of this study was to explore the clinical and image features and detect the mutations of CBFA1 gene in two CCD families.

METHODIn this study, the clinical features were investigated in two CCD families, radiological and CT examinations regarding osseous malformation were carried out over the entire body of these patients with CCD. Blood (2 ml) was drawn from all affected individuals, unaffected family members and one hundred unrelated normal controls, Genomic DNA was extracted from whole blood with PureGene DNA extraction kit and PCR was performed with eight pairs of PCR primers for exons 0 to 7 of the CBFA1 gene. The mutations of CBFA1 gene were screened in these two CCD families.

RESULT(1) The clinical features of patients with CCD include delayed closure of fontanelles, frontal bossing, dysplasia of clavicles, late tooth eruption, and other skeletal anomalies. X-ray and CT examination showed the bulging calvarium, patent fontanelles, wide cranial sutures, multiple Wormian bones, dental dysplasia or aplasia of clavicles. (2) Two mutations were identified, one is novel missense mutation (c.1259C > T[p.T420I]) in CBFA1 gene exon 7, other (c.577C > T[p.R193X]) was reported in Chinese cases with CCD for the first time.

CONCLUSION(1) The clinical and image features of patients in two CCD families include delayed closure of fontanelles, frontal bossing, dysplasia of clavicles, late tooth eruption, and other skeletal anomalies. (2) The T420I and R193X mutations of CBFA1 were reported, expanding the spectrum of CBFA1 mutations causing CCD.

OBJECTIVETo investigate the expression of nesfatin-1/NUCB2 and ghrelin in the gastric mucosa of rats with intrauterine growth retardation (IUGR) and its significance.

METHODSThe IUGR animal model was established by feeding rats low-protein diets during their pregnancy. Newborn rats were divided into catch-up growth, non-catch-up growth and control groups. Protein and mRNA levels of nesfatin-1/NUCB2 and ghrelin in the gastric mucosa of rats were determined by RT-PCR and Western blot, respectively.

RESULTSNesfatin-1/NUCB2 mRNA and protein were expressed in the gastric mucosa of rats immediately after birth, and their expression increased in an age-dependent manner in all three groups. Furthermore, the level of nesfatin-1/NUCB2 in the catch-up growth group was higher than that in the control group before weaning, whereas there was no significant difference in nesfatin-1/NUCB2 expression between the two groups after weaning. The level of nesfatin-1/NUCB2 in the non-catch-up growth group was lower than that in the catch-up growth group during the whole observation period. The level of ghrelin in the catch-up growth group was higher than that in the control group starting from day 12 after birth, whereas there was no significant difference in ghrelin expression between the two groups after weaning. The level of ghrelin in the non-catch-up growth group was lower compared with those in the catch-up growth and control groups from days 12 to 28 after birth.

CONCLUSIONSNesfatin-1 and ghrelin are co-expressed in the gastric mucosa of rats with IUGR after birth and interact with each other to produce long-term nutritional regulation.
