Studies show that heme oxygenase-1 (HO-1) can promote the tumor neovascularization via interacting with angiogenic factors,such as vascular endothelial growth factor (VEGF) and stromal cell-derived factor-1.On the other hand,HO-1 may suppress angiogenesis in tumors via inhibiting the transcription of NF-кB.In a word,HO-1 may participate in the pathophysiological process of tumor angiogenesis,and may be a new target for cancer treatment.

PurposeTo evaluate and describe fetal cardiac development and hemodynamics high risk pregnancy by using ultrasound technique. Methods Two-hundred and thirty-three pregnancies were prospectively studied by using the detailed fetal echocardiographic procedure( fetus gestational age from 19 weeks to 39 weeks). Cardiac chamber size, internal diameter of great arteries were documented together with the presence of inflow and outflow wave patterns. In utero diagnoses of variety of congenital heart defects were also conducted. ResultsCardiac chamber size and internal diameter of great arteries showed a positive correlation with the increasing of gestational age. Left and right ventricles were demonstrated the same size during whole fetal observational period. Blood flow through mitral valve and tricuspid valve were typically 'M' type. By comparing 'e' wave and 'a' wave, this inflow blood velocity pattern was dominant by 'a' wave, though the ratio of a/e gradually decreased during the fetal development period. Blood velocity in aorta and pulmonary artery remained steady along with the gestational age. The detection rate of verity types of congenital heart diseases in this sample population was 5.7% (13 cases) ,the major problem was the complex heart malformation. The occurrence of fetal cardiac arrhythmia was 14 cases (16 % ), with the majority of atrial premature beat. Conclusions Fetal echocardiography can be used to evaluate and monitor the change of cardiac anatomy, structure and hemodymanics during the different gestational age. This has provided a new approach to the further understanding of fetal cardiac development, and is importantto the screening of congenital heart disease during pregnancy.

BACKGROUND:Some studies indicate that PI3K/Akt signaling pathway is associated with the expression of glucose transporter 4 (GLUT4) and the function of cAMP response element binding protein (CREB) in skeletal muscle. However, it is stil unclear whether PI3K/Akt signaling pathway has the effects on CREB and GLUT4 in skeletal muscle of the rats with high-fat diet and treadmil exercise. OBJECTIVE:To investigate whether PI3K/Akt signaling pathway has the effects on CREB and GLUT4 in gastrocnemius muscle of the rats with high-fat diet and treadmil exercise. METHODS:A total of 70 rats were fed with normal diet for 2 weeks, and randomly divided into common feed group (n=20) and high-fat feed group (n=50). Rats in both groups were respectively fed with common feed and high-fat feed for 8 weeks. The rats in the common feed group were equaly assigned to common feed quiet group and common feed exercise group. 20 rats from the high-fat feed group whose body weight was 1.4 times of common rats were randomly and equaly assigned to obese quiet group and obese exercise group. Rats in the quiet groups did not do exercises. Rats in the exercise groups received adaptive sports for 1 week and medium-intensity treadmil exercise for 8 weeks. RESULTS AND CONCLUSION:(1) Impairments of PI3K/Akt signaling pathway appeared in obese rats, however, the quantity of GLUT4 expression did not change obviously in gastrocnemius muscles of obese rats. The reasons for the decrease of the nuclear protein CREB level of gastrocnemius muscles of obese rats might be related to the decrease of pAkt-Ser473 level. (2) The increase of the quantity of GLUT4 expression was accompanied by significantly up-regulated pAkt-Ser473 level by exercise intervention in gastrocnemius muscles of obese rats. Exercise intervention significantly increased the expression of nuclear protein CREB in gastrocnemius muscles of chow-fed rats and obese rats, which was consistent with the changes of pAkt-Ser473. These findings suggest that pAkt-Ser473 can play an important role in the effects of high-fat diet and exercise intervention on GLUT4 and CREB protein expression in gastrocnemius muscles of obese rats.

Objective To explore the efficacy and safety of bedside continuous blood purification (CBP) in the treatment of neonatal multiple organ failure (MOF).Methods Totally 6 newborn infants of MOF were hospitalized in department of neonatology in our hospital from June 2011 to June 2013.These 6 cases of clinical data were retrospectively analyzed,6 neonates were treated with CBP combined with conventional treatment.The model for CBP was continuous veno-venous hemodialysis filtration (CVVHDF),blood flow velocity was 3 to 5 ml/(kg· min),replacement fluid dose was 20 to 30 ml/(kg· h),dialysis fluid dose was 15 to 25 rnl/(min· m2).The clinical outcome measures included,blood pressure,blood pH,K+,Na+,blood urea nitrogen,creatinine,urine volume,PaO2/FiO2 and epinephrine intravenous dose,respectively before CBP treatment,6 h,12 h,24 h,48 h after CBP treatment and the end of CBP treatment.The efficacy of CBP treatment was evaluated in neonatal MOF.Results Gestational age of 6 neonates with MOF was 33 to 41 weeks,2 to 19 days old,2.25 to 3.36 kg birth weight.Primary disease was 4 cases of neonatal septicemia(1 case with congenital hereditary metabolic disease),2 cases of severe neonatal asphyxia.All 6 cases of venous catheter were smoothly done.CBP treatment persisted for 49 to 106 hours.Compared with before CVVHDF treatment,blood K+,blood urea nitrogen,creatinine significantly decreased at 12 h after CVVHDF treatment [(5.32 ± 1.84) mmol/L vs.(9.81 ±3.61) mmol/L,(9.0 ±3.4) mmol/L vs.(12.8 ±6.1) mmol/L,(99 ± 16) μmol/L vs.(176 ±25) μmol/L,P ＜0.05],and reached the normal range at 24 h after treatment,urine volume significantly increased at 24 h after treatment (P ＜ 0.05).PaO2/FiO2 reached 200 mmHg (1 mmHg =0.133 kPa) at 6 h after treatment and more than 300 mmHg at 24 h after treatment(P ＜0.05).Fifty percent of epinephrine intravenous dose were down-regulation at 12 h after treatment and stopped using epinephrine at 48 h after treatment.CBP treatment of 6 cases showed effective.Conclusion Application of bedside CBP treatment in neonatal MOF is safe,can effectively help neonates with MOF to skip over renal failure stage.

Objective To investigate the possible mechanism of Nrf2 in sepsis development and its effect in the septic acute liver injury ,and derive the effect of curcumin on Nrf2 expression ,which provide theoretical basis for clinical prevention and treatment of sepsis .Methods Divided putting 72 male Sprague-Dawley rats into 3 groups:control group ,experimental group and intervention group .After operation ,3 groups were further divided into subgroups 6 hours later ,12 hours later ,24 hours later and 48 hours later respectively .The septic rats model with acute liver injury was reproduced by method of cecal ligation and puncture (CLP) .The ex-perimental group and the intervention group took CLP .The rats in the intervention group were rejected with curcumin in the abdo-men at a dosage of 100 mg/kg an hour after operation .Detected the expression of Nrf2 in the livers of each group used Western blot and measure alanine aminotransferase(ALT ) in serum by drawing the rats′heart blood ;observed the pathological changes in the liver with HE coloration .Results ALT :the values of ALT in the experimental group was significantly increased compared with the control group(P<0 .05);while in the intervention group ,it was markedly improved compared with the experimental group (P<0 . 05) .The expression of Nrf2 :Nrf2 exists in control group rat′s hepatic tissue .In the experimental group ,it was progressively in-creased since the 6 h time point and decreased after the 12 h time point which shown significant decreased compared with the control group(P<0 .05) .In the intervention group ,it was gradually increased since the 6 h time point and decreased after the 24 h time point which was obviously higher than the experimental group(P<0 .05) .Pathological changes :There was no obvious abnormalities in the control group rats′liver structure ,while a lot of inflammatory cells gather and liver cells swell in the experimental group .It was obvious improved after curcumin intervention .Conclusion As Nrf2 is generally lower in the experimental group than in the comparative group ,it shows that Nrf2 directly participates in the occurrence and development of sepsis ,while severe infection blow damages the endogenou s protection system .Decreased activity of Nrf2 causes ignificantly inhibition of anti-oxidative stress and nat-ural immune response ,which may exacerbate acute liver injury by oxidative stress in sepsis .In case of sepsis ,curcumin may increase the level of Nrf2 and the antioxidant enzyme′s activity in the hepatic tissues ,enhancing the general antioxidant ability and alleviating the oxidative stress which points out that curcumin prevents the septic acute liver injury .

Objective To explore the application and efficacy of autogenous septal cartilage in the correction of cleft lip nasal deformity.Methods A total of 31 patients with secondary nasal deformity of cleft lip were involved in this study.After autologous nasal cartilage was released,the dislocation of nasal cartilage was corrected,nasal septum cartilage was used as substitute to raise the alar collapse,to reshape the nasal tip cartilage structure and correct the nasal deformity.Results Postoperative incision was primarily healing.For cartilage donor area there was no serious complications,and incision scar was concealed and unobvious; after 6 months to 2 years follow-up,there was no cartilage absorption deformation,the tip of the nose was flat,crack side nosewing collapses,and nasal columella skew was totally corrected,with stable rhinoplasty effects.Conclusions For secondary nasal deformity of cleft lip,the use of nasal septum cartilage to repair nose deformity can not only solve the cartilage source,but also give septal straightening and at the same time the correction effect of external nasal deformity is good.

Objective To explore the application of washing fluid in the prevention of postoperative incision infection of colorectal cancer. Methods 350 patients with colorectal cancer underwent colorectal surgery from Jan. 2012 to Dec. 2015 were randomly divided into three groups: sterile saline, 0.50% metronidazole, 0.50% Povidone-iodine solution group, while part of the rinse liquid heated to 37 ~38℃ before use, then record the operation time, surgical site, postoperative incision infection, incision infection, timely delivery statistical analysis was performed by using single factor analysis and logistic multivariate regression analysis. Age, operation time, surgical site, type of irrigating fluid and temperature of flushing fluid were analyzed statistically. Results The incision infection rate of the patients ≥60 years old and the operation time ≥2 h was higher than the age <60 years, and the operation time was less than 2 h, P < 0.05, the difference was statistically significant; 0.50% metronidazole, 0.50% Povidone-iodine solution group, the infection rates of 0.50% metronidazole and 0.50% povidone-iodine group were 7.69% and 8.55%, respectively, which were significantly lower than those of the saline group 16.38% The infection rate of the rinsing fluid after heating was 7.22% and 14.71%, respectively, lower than that of the normal temperature rinsing solution (P < 0.05), the difference was statistically significant. Conclusions The risk factors of incisional infection in colorectal cancer patients with colorectal cancer were : ≥60 years of age and ≥2 h of operation, while 0.50%metronidazole, 0.50% povidone-iodine solution and heated washing fluid were protective factors. It can be applied to prevent incision infection after laparoscopic surgery.

Objective To explore the indication and the functional advantages of the high-flexion posterior stabilized (PS) rotating-platform mobile-bearing (RP-MB) total knee system. Methods A prospective randomized, controlled trial was performed. Osteoarthritis was the indicators for total knee arthroplasty.From Feb. 2009 to Apr. 2009, 75 patients (94 knees) were randomly assigned to to receive either a highflexion PS, RP-MB total knee system(PFC sigma RPF) or a standard one (PFC sigma RP). There were no statistical difference in the baselines, the preoperative scores of the Hospital for Special Surgery (HSS) and the knee range of motion (ROM) of both groups. The functional status were assessed with Hospital for Special Surgery and the ROM of the knee at the postoperative 1, 6, 12, 18 months. The satisfaction rates were assessed at the postoperative 18 months. The radiographic measurements were t assessed at the postoperative 3days and 3, 6, 12, 18 months. Results A total of 70 participants (87 knees) completed the 18-month followup. At the time of the final follow-up, the average Hospital for Special Surgery knee score was 92.4±5.0points in the standard group and 94.7±7.0 points in the high-flex ion group. The difference was not statistically significant(P ＞0.05). The average maximal flexion was 131.9±14 degrees in the high-flexion group and 123.0±15.3 degrees in the standard group. There was a statistical difference. But it was not enough to confirm our hypothesis that the difference should be higher than 10 degrees. Moreover, the satisfaction rate were 100% in both groups, and no statistical significant difference was found. Conclusion No significant differences were found between standard and high-flexion posterior-stabilized rotating-platform mobile-bearing total knee prostheses in terms of clinical outcomes or range of motion.
