Compared with the control group, serum and brain contents of MDA, NO and NOS were higher but the content of SOD was lower,and the differences were significant(all P

Objective To observe the effect of low molecular weight heparin(LMWH) in treatment of diabetic foot.Methods Fifty-four patients were divided into test group and control group randomly.Both two groups were given routine therapy including mediating blood glucose with Insulin,anti-infection and changing dressings,while the test group were givon LMWH 5000IU once datly every 12 hours for 15 days besides the routine treatment.Then the endothelin(ET),thromboxaneB2(TXB2),hemorheology,ankle-brachial index(ABI),ulcer healing,fibrinogen(FIB),prothrombin time(PT) and avtivated parital thromboplastin time(APTT) were observed.Results Compared to that of before treatment,there are ET,TXB2,hemorheology and better ulcer heals after treatment,The improvement in test group patients was superior to that of control group(P0.05) after treatment in two groups.No hemorrhage and other complications occurred.Conclusion LMWH is effective and safe for treatment of diabetic foot.

To investigate haplotype distribution of the Y-chromosome STRs (DYS19, DYS390 and DYS389 locus) in Han population in Guangdong area. The STRs were typed by poplymerase chain reaction followed by discontinuous PAGE system. Among 130 unrelated males, 81 different haplotypes were observed, 52 out of them were found only one time. The haplotype genetic diversity, discrimination power and non-father exclusion chance are 0. 9989, 0. 9824, 0. 9824, respectively. The high informative haplotypes make these STRs useful for the forensic individual identification and paternity testing.

Objective To explore the best position in bed for the patients who have under the operation of percutaneous coronary intervention (PCI) and then used heparin sodium within 24 hours. Methods The 159 patients were divided into two groups randomly:the experimental group and the control group. After the PCI, the subjects in these two groups will rest in bed by two ways. Using McGill′s present Pain Index to evaluate hematoma, using the PPI to evaluate the pain of back, using the STAI to evaluate the condition of anxiety, write the number of patient who have anuresises. Results There are no significant difference between two groups in wound blooding, while the difference of back pain, anxiety and the anuresises are significant between two groups. Conclusion The position of half-lie is safe and comfortable for the patients who have under the operation of PCI.

Objective To evaluate the influence of SP600125,a selective c-Jun N-terminal kinase (JNK) inhibitor,on the levels of serum total bile salt (TBA) and Bsep,Ntcp expression in the hepatic tissue of rats with ethinylestradiol induced intrahepatic cholestasis.Methods Rats pregnant for 15days were administered the subcutaneous injection of 17- b -estradiol propylene ( EE ) to modulate the ICP animal models,and be SP600125 to intervene.Testing the level of serum TBA and the expression of c-Jun,Bsep,Ntcp in the hepalatic tissue.Results The average gray values of c-Jun in the group of ICP models were significantly lower than the normal control group ( 101.05 ± 5.20 vs 118.99 ± 5.95,P ＜ 0.05 ).After the intervention of SP600125,comparing with the group of ICP models,the expression of Bsep,Ntcp in the group of SP600125 intervention were significantly higher,and this change in the high dose of SP600125 intervention group was more obvious ( low dose intervention group Bsep:0.452 ±0.031 vs 0.291 ±0.043,Ntcp:0.462 ± 0.015 vs 0.285 ± 0.021,P ＜ 0.05 ; high dose intervention group Bsep:0.568 ± 0.038 vs 0.291 ±0.043,Ntcp:0.605±0.020 vs 0.285 ±0.021,P ＜0.05),while the level of TBA in the serum was significantly lower.Conclusions Treatment with SP600125 can down-regulate the level of c-Jun/AP-1,and it may participate in the lower expression of Bsep、Ntcp in the ICP rats which were induced by 17-bestradiol.

Objective To investigate the risk factors,clinical prediction and intrapartum management of shoulder dystocia in non-macrosomia.Methods Totally 7 811 cases of vaginal delivery were retrospectively reviewed from Juanary 2009 to December 2013 in Shengjing Hospital.Shoulder dystocia was found in 11 cases (0.14％,11/7 811),including 1 case of macrosomia and l0 cases of non-macrosomia (shoulder dystocia group).Each non-macrosomia shoulder dystocia case was matched with 10 cases of normal delivery in the same week,which were selected randomly as the control group.The tendency and risk factors of shoulder dystocia in macrosomia and non-macrosomia were analyzed,and the following data between the two groups were compared,including the height of uterus fundus,abdominal circumference of the pregnant woman,the increasing of body mass index(BMI),fetal biparietal diameter (BPD),fetal femur length (FL),duration of every stage of labor,birth weight of the newborn,head circumference and chest circumference of the newborn,Apgar score.Results (1) There were 213 macrosomias among the 7 811 vaginal deliveries,with the incidence of 2.73％ (213/7 811).Only 1 shoulder dystocia was macrosomia (0.46％,1/213); while the other 10 cases were non-macrosomia (0.13％,10/7 598).(2) From 2009 to 2013,the macrosomia happened by 24 cases (2.32％,24/1 034),42 cases (3.61％,42/1 164),46 cases (2.60％,46/1 772),62 cases (3.01％,62/2 060),39 cases (2.19％,39/1781),respectively.The incidence of macrosomia had no significant difference among these 5 years (P＞0.05).The shoulder dystosia occurrence without macrosia in these 5 years were 1 case (0.10％,1/1 034),3 cases (0.26％,3/1 164),2 eases (0.11％,2/1 172),2 cases (0.10％,2/2 060),2 cases (0.11％,1/1 781),respectively.The incidence of shoulder dystocia without macrosomia had no significant difference among these 5 years (P＞0.05).(3) In the should dystocia group,5 cases were complicated with premature rupture of membrane (5/10),4 cases were mother≥ 35 years old (4/10),3 cases were multipara(3/10),3 cases had gestational diabetes mellitus(3/10),3 cases were occiput posterior during the first stage of labor(3/10),3 cases had prolonged second stage of labor (3/10) and 6 cases had routine lateral incision (6/10).In the control group,3 cases were complicated with premature rupture of membrane(3/10); 1 case was mother≥35 years old (1/10); 2 cases were multipara(2/10),3 cases had gestational diabetes mellitus (3/10),1 case had prolonged second stage (1/10) and 7 cases had routine lateral incision (7/10).(4) There were no significant difference in the height of uterus fundus,BMI,BPD,FL,and duration of the first stage of labor between the shoulder dystocia group and the control group (P＞0.05).Compared with the control group,the increasing of BMI [(6.8±3.1) vs (4.8± 1.4) kg/m2],the time of the second stage of labor[(86±65) vs (38±28) minutes] and abdominal circumference[(108±8) vs (101±7) cm] were significantly higher in the shoulder dystosia group (P＜0.05).(5)There were significant difference in the chest circumference of the newborn [(34.0±1.6) vs (32.2±1.9) cm] and the ratio of chest circumference to head circumference of the newborn [(0.99±0.03) vs (0.97±0.03)] between the two groups(P＜0.05).The 1-minute Apgar score of the newborn (7.4±2.8) was significantly lower than the control group (10.0±0.0) (P＜0.01).Clavicular fracture occurred in 3 newborns and brachial plexus injury occurred in 4 newborns in the shoulder dystosia group.Conclusion It is difficult to predict shoulder dystocia in non-macrosomia.Shoulder dystocia of non-macrosomia could be predicted by measurement of the head circumference,chest circumference,the ratio of chest circunfference to head circumference by using prenatal ultrasound.The risk factors may complicated with premature rupture of membrane,abnormal occiput position during the first stage of labor and prolonged second stage of labor.
