Objective To explore the abdomen surgical incision infection risk factors,and to put forward prevention countermeasures.Methods 1 854 patients with abdominal surgery were selected as subjects.According to whether had surgical incision infection,they were divided into the infection group(76 cases)and the non -infection group(1 778 cases).Single factor analysis and Pearson correlation analysis were used to summarize abdominal surgical incision infection risk factors.Results Single factor analysis results showed that age,BMI,category of incision,operation timing,operation time,diabetes mellitus,drainage tube placement,summer were risk factors for abdominal surgery incision infection (t or χ2 =8.925,5.840,5.376,5.445,5.846,19.674,5.846,19.674,all P <0.05).Pearson correlation analysis showed that age,BMI,category of incision,operation timing,operation time,diabetes mellitus, drainage tube placement and summer surgery were risk factors for abdominal surgery incision infection (r =0.746, 0.689,0.746,0.689,0.691,0.548,0.760,0.548,all P <0.05).Conclusion Abdominal surgery incision infection is associated with many factors.It is necessary for all kinds of risk factors for targeted intervention to reduce incision infection rate.

Objectives To investigate the outcomes of neonatals with abnormal hepatitis B virus (HBV) serological markers. Methods Twenty-eight neonatals who had abnormal HBV serological markers and whose mothers had positive HBsAg, HbeAg and HbcAb were studied. Among them, 21 neonatals who had positive HBsAg, HbeAg and HbcAb were included in vertical transmission group;7 neonatals who had positive HbeAg, HbcAb and negative HBsAg were included in suspicious group. The quantities of HBV serological markers were determined by time-resolved immunofluorometric assay (IFMA) and the level of HBV DNA were measured by fluorescence quantitative PCR (FQ-PCR). Results Serum HBeAg and HBsAg levels in suspi-cious group were lower than those in vertical transmission group (P<0.05). The results showed that HBeAg level (0.55 ± 0.19 PEIU/ml) three months after birth was lower than that (4.02 ± 2.00 PEIU/ml) 7 days after birth in suspicious group (P<0.05). Conclusions Early interference has positive effect in mothers and neonatls with abnormal HBV serological markers.

It has been reported that the level of antioxidants is lower in obese patients compared with that in normal weight subjects. Important antioxidants, vitamin E and ?-carotene, are lowered in obese adults and children, which may cause lipid super oxidation and are associated with atherosclerosis, coronary heart disease and myocardial infarction. Copper and zinc are trace elements that compose parts of enzymes such as CuZn-superoxide dismutase (CuZn-SOD) which can scavenge free radicals. Plasma copper and zinc levels are lowered in obese individuals, which may lead to abnormality in glucose metabolism.

Perfusion computed tomography (CT) imaging is a kind of functional imaging technique to evaluate and determine the hepatic and portal blood flow noninvasively.It offers the significant clinical advantages in the early diagnosis,evaluation of treatment response,and prognosis assessment in chronic liver diseases.In this article,we reviewed the principle,scanning protocol,clinical applications,and advances in chronic liver diseases of hepatic perfusion CT imaging.

A Review Many studies indicate that apoptosis is involved in the progression of congestive heart failure. At present, mechanisms that mitochondria regulates cell apoptosis is widely accepted.Cardiac myocytes have abundant mitochondria,which plays an important role in maintenance of cell physiological function. Recent studies find that cardiac energy metabolic shifts occur as a normal response to diverse physiologic and dietary conditions and as a component of the pathophysiologic processes which accompany cardiac hypertrophy, heart failure, and myocardial ischemia.Both clinical and experimental studies show that cardiac function can be improved and apoptosis is inhibited by intervention in energetic metabolism of myocytes.

Objective To explore the clinical value of prenatal screening by detecting α-fetoprotein(AFP),β-human chorionic gonadotrophin(β-HCG)and free estriol(u-E3)levels in the second trimester of pregnancy.Methods AFP,β-HCG and u-E3 were de-tected in 3 595 second trimester pregnant women by chemiluminescence.The risk value was calculated by combining with the factors of age,pregnant weeks,body weight,etc.Then the high-risk pregnant women were carried out the amniotic fluid cells chromosome karyotype analysis and B-ultrasonic examination.Results Among 3 595 pregnant women,the screening positive rates of Down′s syndrome(DS),Edward′s syndrome(ES)and neural tube defects(NTD)were 3.70%(133/3 595),0.11%(4/3 595)and 1.44%(52/3 595)respectively.In the prenatal screening,there were 189 cases of high risk pregnant women,among them 87 cases were per-formed the prenatal diagnosis of amniotic fluid cells chromosome karyotype analysis and B-ultrasonic examination,6 cases were defi-nitely diagnosed,in which 3 cases were DS,2 cases were NTD and 1 case was ES.Conclusion Prenatal screening is a non-invasive detection method and has the important clinical application value for avoiding the birth of DS,ES and NTD neonates.

BACKGROUND:Despite regular mesh hydroxyapatite has certain biocompatibility and bone conductivity, it cannot be absorbed by human body after transplantation, and wil affect the growth and eruption of maxila and fangs when using for filing the injured alveolar cleft. OBJECTIVE: To compare the effect of conventional and new mesh hydroxyapatite composites in repair of alveolar cleft defects. METHODS: Totaly 46 patients with cleft lip and palate were randomly and evenly divided into test and control groups, and al were arranged according to cleft lip and palate sequence treatment. After nasal soft tissue defect repair, new mesh hydroxyapatite composite bone material (hydroxyapatite and bone morphogenetic protein compound). Conventional mesh hydroxyapatite material was adopted in the test and control groups, respectively. Within 6 months after the repair, the vertical distance from the newly formed bone tissue plane to the top of alveolar ridge was observed. The clinical repair effect was comprehensively evaluated from the aspects of complications, alveolar cleft shape and size, calus formation and material absorption. RESULTS AND CONCLUSION: At 2, 4, 8, 12 and 24 weeks, the vertical distance from the newly formed bone tissue plane to the top of alveolar ridge in the test group was higher than that in the control group (P < 0.05). The clinical repairing significant efficiency and total effective rate were al higher than those in the control group (P< 0.05). These results show that new mesh hydroxyapatite composite bone materials in the repair of alveolar cleft defects have good bone osteoinductivity and biocompatibility, rare complications and rapid calus formation.
