This study examined the expression and distribution of angiopoietin-1/-2 (Ang-1/-2) in the endometrium of early pregnant mice. The expression of Ang-1/-2 was detected by immunohisto-chemical staining and in situ hybridization respectively. Computerized image analysis system was used to measure the average optical intensity of Ang-1/-2 in endometria at different time points after gestation. Mice were randomly divided into 5 groups: control group, D2 group (2 days after pregnancy), D4 group (4 days after pregnancy), D6 group (6 days after pregnancy) and D8 group (8 days after pregnancy), each containing 15 mice. The results showed that the expression of Ang-1 and Ang-2 was very different among 4 groups (P<0.01). Immunohistochemical staining revealed that Ang-1 was localized in the cytoplasma of stromal cells 2 days after pregnancy (day 2), and in luminal epithelial cells on day 4. The protein of Ang-2 was mainly expressed in the cytoplasma of glandular epithelia and stromal cells. With gestation time, the positive reactions of Ang-1/-2 were stronger in the endometria of the pregnant mice (P<0.01). In situ hybridization showed Ang-1 mRNA in stromal cells on day 2. Hybridization signal was localized in both stromal cells and vessel epithelial cells on day 4; Ang-2 mRNA was expressed in stromal cells and glandular epithelia on day 2; high mRNA levels appeared in stromal cells, glandular epithelia and vascular endothelia on day 4; an increasing in mRNA expression of Ang-1/-2 was observed on day 6 and day 8 (P<0.01). It is suggested that Ang-1/-2 may play an important role in the cross-talk between blastocyst and maternal endometrium during the process of embryo implantation.

Varicose veins is the main clinical manifestations of the chronic venous insufficiency.TIPP transilluminated powered phlebectomy,a new minimally invasive surgery,received much attention while surgical techniques aimed at treating varicose vein were constantly updated.In this article,TIPP in the varicose vein surgery is reviewed from its history,operating techniques and advantages,and TIPP's future is being prospected.

Calcium-sensing receptor(CaSR)is expressed in human parathyroid cells and renal tubular epithelial cells mainly.CaSR could control parathyroid hormone(PTH)secretion and the renal tubular's handing of the electrolytes and water.This receptor plays a central role in extracellular calcium homeostasis,and involves in the process of bone remodeling.The change of CaSR function,including anti-CaSR antibodies,CasR gene mutations or any part impairment in CaSR signaling pathway,not only results in the imbalaance of PTH and calcium homeostasis.but also relates to disorders of bone remodeling and renal tubular's mishandling in the electrolytes and water,which contribute to hyperparathyroidism.It makes possible clinical Use of cinacalcet in hyperparathyroidism in theory.

Objective To investigate the early diagnosis and rational treatment of popliteal artery injury so as to im-prove the lower limb salvage rate. Methods The clinical and follow-up data integrity of 25 patients with popliteal artery injury was systematically studied. In these patients , 19(76%)cases were blunt injury and 6(24%) cases were penetrating injury. The combined injury included open fracture in 10 cases(40%) ,the knee joint dislocation with closed fracture of lower limb in 13(52%),nerve injury in 5(20%) and venous injury in 3(12%),respective-ly. The cause of delayed diagnosis and relationship between prognosis and type of injury, complications, the dura-tion from injured to treatment time were analyzed. Results 20 cases were operated to repair the popliteal artery. Endovascular treatment in 5 cases, the blood supply completely recovered (64%) in 16 cases, improved in 3 cases (12%) , 6 cases (24%) amputed, respectively. Rate of amputation within 6~8 hours was significantly lower than that of the more than 8 hours from the injuried to treatment time ( P<0. 05 ) . Amputation rate in blunt injury and combined injury was significantly higher than that of sharp injury ( P<0. 05 ) . Conclusion The duration from inju-ry to surgery more than 8 h, combined with knee joint dislocation and wound around knee is a major cause of mor-bidity. Operation with arterial thrombectomy is the main treatment, while endovascular treatment is a complementa-ry treatment to save the lower limb.

Objective: To evaluate the effects of percutaneous balloon pulmonary valvuloplasty ( PBPV) for pulmonary valve stenosis (PS) by single-balloon, double-balloon and Inoue-balloon methods. Methods: PBPV was performed in 42 patients with PS. The systolic right ventricular pressure (SRVP) , systolic right ventricular outflow pressure and systolic pulmonary arterial pressure ( SPAP) were contrasted before and after the procedure. Systolic transpulmonary valve pressure gradient (TVPG) and total pressure gradient from right ventricular to pulmonary arterial after the procedure were compared among the three gropes. Results:SRVP, SRVOP were decreased from (14. 69?6. 01 )kPa, (12. 16?3. 48)kPa to (8.14?5.26)kPa, (5.39?2.21)kPa and PAP increased from (1.57?0.56)cm to (17. 16? 2.16)cm after PBPV, respectively. TVPGs were (2. 40?2. 05) kPa, (3. 29?2. 25 ) kPa, (2.52? 1.95)kPa and TPGs were (2. 40?2. 05)kPa, (4.98?4.26)kPa, (6.16?6.93)kPa, (5.65?4.75) kPa after PBPV by single balloon, double balloon and Inoue balloon methods, respectively. During the follow-up period (2. 5?1. 6) years, bloodflow velocity at pulmonary valve measured by supersonic Doppler decreased from (2. 38?1. 89) m/s immediately after PBPV to (2.22?1. 96) m/s, further TVPG decreasing was indicated. Conclusion: The short and long term results of PBPV for PS by each of the three methods were excellent. Inoue balloon may be the first choice for elder children and adults, while for younger children, single balloon method may be preferred. Double balloon method can be remained as the second choice when Inoue method failed.

Objective To investigate the seasonal variability of the onset of acute deep vein thrombosis(DVT).Methods The clinical manifestations in 774 DVT patients during January 2008 to December 2012 were collected and circular distribution statistics was used to identify seasonal variability.Results The total sample had the significant seasonal variability (P ＜ 0.01):DVT was most frequent in winter while less frequent in summer and the peak day was January 1.Female subgroup has significant seasonal variability (P ＜0.01):on peak in winter and at trough in summer while male subgroup has no significant seasonal variability (P ＜ 0.01).Different age subgroups (＜ 40 years,40-69 years,＜70 years)have significant seasonal variability(P ＜ 0.05,P ＜ 0.01,P ＜ 0.01).DVT was most common in December and less frequent in August.Left lower limb subgroup and both lower limb subgroup has significant seasonal variability (P ＜ 0.01,P ＜ 0.01),on peak in December-January.Immobilization subgroup also has significant seasonal variability (P ＜ 0.001):frequent in winter,January 1 is on the peak.Conclusions DVT has significant seasonal variability in onset:it is most frequently seen in winter while less frequent in summer.Some subgroups (female,＜70 years and immobilization) have the most significant seasonal variability in onset.

Objective To evaluate outcomes of endovascular procedures for atherosclerosis obliterans (ASO) patients with diabetes mellitus (DM).Methods Data of patients undergoing endovascular procedures for atherosclerosis obliterans at the First Affiliated Hospital of Anhui Medical University from January 2012 to December 2014 were retrospectively analyzed,disease characteristics,technical success rate,perioperative complications,ankle brachial index (ABI) improvement,clinical success rate,rest pain alleviating rate,limb salvage rate and survival rate were compared between the two groups.Results There were 144 patients (153 limbs) who received endovascular procedures,including 52 patients (56 limbs) with DM and 92 patients (97 limbs) without DM.Mean follow-up was 15 months.All patients experienced significant ABI improvement (P ＜ 0.05).There was no significant difference in technical success rate (80.4％ vs 90.7％),perioperative complications rate(19.6％ vs 24.7％),1 year rest pain alleviating rate (75.0％ vs 85.6％),1 year limb salvage rate (91.1％ vs 95.6％) and 1 year survival rate (92.3％ vs 90.2％) between diabetic and non-diabetic groups (P ＞ 0.05),but there was less 1 year clinical success rate in diabetic group (78.6％ vs 88.6％,P ＜ 0.05).Conclusions Compared to nondiabetic paitents,endovascular procedures for patients with DM has similar efficacy,when the procedures are properly undertaken and postoperative correct medication are given.

Objective To study the correlation between male primary varicose vein of the lower extremity and varicocele.Methods 100 male patients with varicose vein of the lower extremity were compared with 100 male adults without varicose vein of the lower extremity for the prevalence of varicocele by using ultrasonography.Results There is no difference of demographic data between the two groups (t =1.78,P ＞ 0.05).There were 49 (49.0％) patients found with varicoele in study group compared with 19 (19.0％) patients with varicoele in control group (x2 =20.05,P ＜ 0.01).We compared the rate of varicoele and the mean diameter of spermatic vein between the patients having reflux in the saphenofemoral junction or not,and found there was no statistical difference between themn (rate of varicose P ＞ 0.05,diameter P ＞ 0.05).In patients with both lower extremity varicose vein and varicocele there was a linear correlation between spermatic vein diameter and that of varicose vein (rs =0.407 2,P ＜ 0.01).When patients in study group were classified into six grades by Clinical-Etiology-Anatomy-Pathophysiology (CEAP) trend chi-square found no difference in the incidence of varicoele (x2 =0.879 8,P ＞ 0.05),nor the mean diameter of spermatic vein in different grades (F =1.59,P ＞ 0.05).Conclusion There is a correlation between varicose vein of the lower extremity and the pathogcnesis of varicocele.

Objective To determine whether the presence of coronary collateral lfow, as evidenced by angiography, has a beneifcial effect on left ventricular function in ST-segment-elevation myocardial infarction (STEMI) treated by means of early percutaneous coronary intervention (PCI). Methods Between April 2012 to November 2013, 95 patients with STEMI treated with primary PCI successfully were analyzed. According to the Rentrop grade, these patients were divided into 2 groups:collateral circulation group (n=16) and non-collateral circulation group (n=79). The left ventricular function was evaluated within 24 hours after PCI and 30 days later. Results Comparison of 2 groups showed that collateral lfow was associated with better left ventricular ejection fraction within 24 hours and 30 days after PCI. And non-collateral lfwa was associated with more ventricular aneurysm formation. Conclusions The presence of angiographically detectable collaterals has a protective effect on left ventricular function in ST-segment-elevation myocardial infarction (STEMI) treated by primary PCI.
