Objective To compare proximal femoral nail(PFN)introduction by percutaneous K-wire through a small incision with conventional PFN introduction protocol in the treatment of intertrochanteric fractures. Methods From January 2004 to March 2005,51 patients with intertrochanteric fractures were randomly dis- tributed into a minimally invasive treatment group(group MI)and a conventional treatment group(group C).All the fractures were closely reduced.In group MI a K-wire was percutaneously inserted through the tip of the greater troehanter into the center of medullary canal of the pruximal femur before the PFN was inserted under the guidance of K-wire through a small incision made along the K-wire while in group C the PFN was introduced according to the conventional procedure.The operation time,intra-operative blood loss,length of incision,X-ray exposure,duration of in-patient stay and time of bone union in both groups were recorded and compared.Results The mean oper- ation time,mean intraoperative blood loss and mean length of incisions in group MI were 77.20 min,104.20 mL and 5.12 cm respectively and significantly lower than those in group C(P＜0.01).The X-ray exposure and the reduction time in group MI lasted longer than in group C(P＜0.01).The mean time of bone union and in-patient stay in both groups were nearly equal(P＞0.05).At the latest tollow-up,all the fractures united in both groups without nonuuion or delayed union.Conclusion Compared with the conventional protocol,introduction of PFN by a pereutaneuus K-wire inserted into the central medullary canal of the proximal femur is much more minimally in- vasive and effective.

To study the effect of cholesterol and 25-OH-cholesterol on cholesterol metabolism in HepG2 cells and the effect of coptisine (Cop) extracted from Coptidis Rhizoma (CR) in reducing and regulating cholesterol. In this study, TC, TG, LDL-c and HDL-c were measured by biochemical analysis; mRNA and protein expressions of LDLR, HMGCR and CYP7A1 were detected by qRT-PCR and Western blot. According to the results, cholesterol and 25-OH-cholesterol inducing could decrease in mRNA and protein expressions of LDLR and CYP7A1, so as to increase TC and LDL-c contents. However, Cop could up-regulate mRNA and protein expressions of LDLR and CYP7A1 and down-regulate that of HMGCR, so as to reduce TC and LDL-c levels. These findings suggested that Cop has potential pharmacological activity for reducing cholesterol, and may reduce cholesterol by regulating mRNA and protein expressions of key genes involved in cholesterol metabolism, such as LDLR, CYP7A1 and HMGCR. This study laid a firm theoretical foundation for developing new natural drugs with the cholesterol-lowering activity.

Purpose To detect the incidence rate, average age and the expression of hMLH-1 and hMSH-2 of sporadic colorectal carci-noma ( SCC) with Han and Uygur patients. Methods The expression of hMLH-1 and hMSH-2 was detected in SCC for 60 cases of Uygur and 196 cases of Han by immunohistochemical method, including 60 Uygur and Han cases normal colorectal mucosa ( NCM) . Results The positive rate of hMLH-1 and hMSH-2 proteins expression in the NCM was 100%. There was a marked difference in the positive rate of hMLH-1 in SCC between Han (93. 4%, 183/196)and Uygur (75%, 45/60) (P<0. 05). There was no significance in the positive rate of hMSH-2 in NCM between Han (94. 4%, 185/196) and Uygur (91. 7%, 55/60) (P>0. 05). The average age of Han and Uygur SCC patients were 65. 64 years, 57. 63 years, respectively, and Uygur SCC cases were more likely to be diagnosed at less 40 years old (P<0. 05). The positive rate of hMLH-1 and hMSH-2 expression in the tubular adenoma was 100%. The positive rate of hMLH-1 and hMSH-2 expression in the tubulovillous adenoma in Uygur and Han were 66. 7%( 2/3 ) and 66. 7%( 2/3 ) , and 74. 2%(23/31) and 90. 3%(28/31), respectively, significantly lower than those of tubular adenoma (P<0. 05). The expression of hMLH-1 was positively correlated with that of hMSH-2 in SCC in Han(rs =0. 737, P<0. 05). The expression of hMLH-1 was positive-ly correlated with that of hMSH-2 in SCC in Uygur(rs =0. 383, P<0. 05). There exists marked difference in the positive rate of hM-LH-1 and hMSH-2 among difference age groups (P<0. 05). Conclusion There is a certain loss of hMLH-1 and hMSH-2 expression in SCC in Han and Uygur Chinese, which is related to adenoma and age. The expression of hMLH-1 in SCC tissue among Uygur pa-tients is not resemble to those of Han patients. The average age of Uygur SCC patients is younger than Han, and the positive rate of hMLH-1 is higher. Combined detection of hMLH-1 and hMSH-2 proteins may be used for judging the severity and prognosis of SCC in Xinjiang, which helps improve patients’ treatment program and rationalize their choices.

Objective To evaluate the early clinical efficaoy of hybrid procedure for infants less than six months old with ventricular septal defect and coarctation of aorta.Methods From January 2010 to July 2011,20 patients with ventricular septal defect and coarctation of aorta received hybrid procedure in our center.The body weight was (4.5 ± 1.6) kg ( ranged from 1.9 kg to 6.5 kg) and the age was ( 56 ± 45 ) days ( ranged from 18 days to 6 months).The pressure gradient of the coarctation of the aorta ranged from 30 mm Hg to 56 mm Hg,5 patients of them were diagnosed as hypoplasty of aortic arch.The size of the ventricular septal defect ranged from 8 mm to 16 mm.Results The mortality was zero in all the 20 cases during the surgery,and the mobidity was 20％ (4/20).The complications were pneumonia in 2 cases,infective endocarditis in 1 case and pneumothorax in 1 case.The diameter of coarctation of the aorta ranged from 1.5 mm to 3.4 mm,and the size of the balloon ranged from 4 mm to 12 mm.The pressure gradient of the coarctation of the aorta decreased to 0 to 27 mm Hg.The bypass time ranged from 40 minutes to 87 minutes,and the crossclamp time of the aorta ranged from 20 minutes to 41minutes.The atrial septal defects were repaired and the patent ductuses were ligated during the surgery without leaving the sternum open.The total operation time was (4.0 ± 0.7 ) hours ( ranging from 3.0 hours to 5.2 hours).The mean ventilation time was (2.2 ± 1.4) days and mean ICU stay time was (5 ± 3 ) days.All the patients were followed up for ( 10.0 ± 3.6) months without aneurysm in arch and obstruction in airway.The residual obstructive pressurc gradicnt in the aortic arch ranged from 12 mm Hg to 35 mm Hg and 2 patients received reintervention.One patient received re-balloon dilation and the other received surgery.The cardiac function reached NYHA Ⅰ - Ⅱ in all eases.Conclusion The early outcome of the hybrid procedure (balloon dilation of the coartation of the aorta and surgical repair of ventricular septal defect) for infants with ventricular septal defect and coarctation of aorta was satisfying,which could avoid from circulatory arrest.It is a relatively safe procedure which could be the optional method for one-stage surgical repair.

To explore the relationship between maternal insulin levels and fetal insulin resistance.Maternal blood and venous cord blood samples were collected in gestational diabetes mellitus (GDM) mothers and control subjects.The glucose and insulin levels were measured and insulin resistance levels estimated.Maternal levels of insulin and homeostasis model of assessment for insulin resistance index (HOMAIR) were significantly higher in the GDM group than those in the control group (P ＜ 0.05) ; fetal levels of insulin and HOMA-IR were significantly higher in the GDM group than in the control group (P ＜ 0.05).Maternal insulin level positively correlated with fetal insulin (r =0.326,P ＜ 0.05) and HOMA-IR levels (r =0.378,P ＜0.05).In this study,a higher level of fetal insulin resistance was reported in the GDM group.And maternal hyperinsulinemia might affect fetal insulin resistance in pregnant women with GDM.

By reverse transcription-polymerase chain reaction (RT-PCR), an open reading frame of pathogenesis-related protein 1 (PR1) was isolated from Panax notoginseng and named as PnPR1. Molecular and bioinformatic analyses of PnPR1 revealed that an open reading frame of 501 bp was predicted to encode a 166-amino acid protein with a deduced molecular mass of 18.1 kD. Homology analysis showed that the deduced amino acid sequence of PR1 protein of Panax notoginseng had a high similarity with other higher plants had the same conservative structure domain of cysteine-rich secretory protein (CAP). The recombinant expressed plasmid pET28a(+)-PnPR1 was expressed in Escherichia coli BL21. The expression conditions were optimized by induction at different times, different temperatures, different IPTG concentrations and different giving times. The optimum expression condition was 0.4 mmol.L-1 IPTG at 28 degrees C for 20 h. The successful expression of PnPR1 provides some basis for protein purification and preparation of the monoclonal antibody.

BACKGROUND:Large numbers of experimental data have confirmed that bone marrow mesenchymal stem cel s have a positive therapeutic effect on cerebral ischemia-reperfusion injury, but there are few reports about intravenous administration of bone marrow mesenchymal stem cel conditioned medium in the treatment of stroke.
OBJECTIVE:To investigate the effects of the conditioned medium of rat bone marrow mesenchymal stem cel s on the recovery of neurological function in rats after cerebral ischemia-reperfusion injury.
METHODS:The bone marrow mesenchymal stem cel s were isolated from rat bone marrow. When cel s at passage 2 or 3 reached 90%confluence, the original culture medium was removed. Then the cel s were cultured in serum-free DMEM for 18 hours. After that, the culture solution was col ected as the conditioned medium of rat bone marrow mesenchymal stem cel s. Adult rats were subjected to 2 hours of right middle cerebral artery occlusion. Ischemia-reperfusion injury rats were randomly assigned to three groups:control group, simple culture medium group and conditioned medium group, and respectively given injection of normal saline, DMEM, conditioned medium (10 mL/kg) via the tail vein at 2, 24, 48 hours after operation.
RESULTS AND CONCLUSION:There was no difference in the behavioral tests among the three groups at postoperative 2 hours (P>0.05). Compared with the control and simple culture medium group, neurological impairment was significantly improved in the conditioned medium group at postoperative 1, 3, 5 days (P<0.05), but there was no significant difference between the control and simple culture medium groups. At postoperative 5 days, brain edema was significantly eased in the conditioned medium group in comparison to the control and simple culture medium groups (P<0.05), and there was also no difference between the latter two groups (P>0.05). These results suggest that rat bone marrow mesenchymal stem cel s-conditioned medium via intravenous administration can significantly ease brain edema and improve the neurologic function after cerebral ischemia-reperfusion injury.
