Objective To investigate the correlation of endothelial function variation with pulse pressure index in Uygur acute coronary syndrome patients in Xinjiang. Methods Uygur patients were divided into acute coronary syndrome group (n=208) and control group (n=157) according to their Coronary angiography results. Height, weight and blood pressure were measured on admission and basic medical history were recorded. Fasting blood glucose (FBG), three acyl glycerin (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) were ex-amined using fasting venous blood;Plasma Coagulation FactorⅧ(CFⅧ) and von Willebrand factor(vWF)were examined using ELISA. Results There are no statistical difference in age, gender, history of hypertension, diabetes history, history of smoking, drinking, body mass index, PPI, HDL-C and FBG between two groups. The systolic pressure, diastolic blood pres-sure, pulse pressure, TG, TC, LDL-C and vWF, CFⅧlevels in acute coronary syndrome group were higher than those in the control group (all P<0.05). The levels of plasma vWF and CFⅧwere positively correlated with pulse pressure and PPI, it also was positively correlated between the levels of plasma vWF and CFⅧ(P<0.01). Conclusion The endothelial func-tion was significantly impaired in Xinjiang Uygur patients with acute coronary syndromes, and vascular endothelial damage was positively correlated with pulse pressure and PPI. The pulse pressure and PPI can be used to evaluate the vascular endo-thelial function indirectly.

The genetic divergence between geographically separated populations can be studied by comparing the divergences in their allele frequencies to the geographical distance of popula-tions. The present study is to examine the divergences in allele frequencies and genetic diver-gence in relation to the geogrephical distance of the samples localities, in order to test the population structure model of Oncomelania from the endemic areas in mainland China.The results showed that three patterns of allele frequency distributions occured in seven polymorphic loci, which were even,chaotic and discontinuous cline distributions. The distcon-tinuous or stepped clines shown in loci Est-4,Got and Mdh-2 suggested that the discrete subpopuation model is the likeliest. The plot of genetic distance (Nei's 1978) between sample populations against the geographic distances suggested that the special pattern of allele fre-quency distribution could be found. The regression analysis shows that logistic sigmoid re-gression is the best model to fit the original data in the plot. This supports the existence of the discrete subpopulations model in the population structure studied.

Objective To evaluate the different arteriographic manifestations of acute renal arterial hemorrhage,and the treatment effects of emergency interventional embolization.Methods 87 patients with renal arterial hemorrhage who were failed to conservative treatment underwent the renal arteriography to confirm the position and degree of lesion.According to the arteriographic manifesta-tions,appropriate embolic agents such as spring coil,acrylic acid microspheres and the like were used to embolize the targeted vessel. The arteriographic manifestations and embolization efficacy were retrospectively analyzed.Results Contrast medium leakage was showed by renal angiography in 43 patients,13 of whom had arterio-venous fistula (AVF)and 1 5 of whom had renal pseudoaneu-rysms (RAP).Among this 1 5 patients,there were 5 patients with arteriovenous fistula and one patiernt with artery-calyces fistula. Hemorrhage of tumor vessel was shown in 1 5 patients and renal arteriovenous malformation (RAVM)in 1.47 patients underwent renal artery CT arteriography before emergency interventional embolization.The hematuresis was completely stopped or significantly relieved in 82 of all patients.Only 3 patients with renal trauma and 2 patients with percutaneous nephroscope were still had haematu-ria.All patients were followed up for 2 years.The total effective rate of emergency interventional embolization treatment was 94.25%(82/87),and no serious complications were observed.Conclusion As a safe,effective and micro-invasive treatment,emergency in-terventional embolization therapy can be used to treat the acute renal hemorrhage effectively.It can keep the maximum renal func-tion.Though acute renal hemorrhage angiography may have different manifestations,the choice of embolic agents is the key to stop the symptom.Renal artery CTA before embolotherapy is important for the diagnosis and therapy of acute renal hemorrhage.

Objective To establish a new canine model of ureter trauma to observe the protective effect of biodegradable ureteral stent on renal function following traumatic ureter injury. Methods A self-made device was used to make firearm fragment wounds unilaterally on the ureters in nine Beagle dogs (model group). The wounds were debrided and sutured and the results were evaluated by using intravenous pyelography (IVP) and radioactive renography at 40, 80 and 120 days postoperatively. Firearm fragment wounds were made to the bilateral ureters of nine Beagle dogs in the positive control group, in which a biodegradable stent was placed in one side and a double-J stent placed in the other side. Results In model group, hydronephrosis and hydroureter occurred and got worse postoperatively on the wounded side in all nine Beagle dogs, while none of these symptoms were found in any animals in the control group. The ratios of biodegradable stent side to double-J stent side were increased in renal patial concertration index and half time of kidney washout, but neither showed significant differences. However,vesicoureteral reflux (VUR) was not found in the biodegradable stent side, but in the double -J stent side. Conclusions A new canine model of firearm fragment wounds is successfully developed. Both the biodegradable and double-J stent play important roles in support and drainage and show no significant difference in aspects of renal uptake and half time of kidney washout. The biodegradable stent can effectively prevent VUR.

Objective:
To explore the clinical and laboratory characteristics and therapeutic effect of acute promyelocytic leukemia (APL) with t(2;17;15).
Methods:
The G-banding technique was used for karyotypic analysis in a female patient with APL who was admitted to the First Affiliated Hospital of Zhengzhou University in December 2018. PML-RARα fusion gene was quickly detected by fluorescence in situ hybridization (FISH). The real-time quantitative polymerase chain reaction (RT-PCR) was used to detection 43 kinds of fusion gene, and the gene mutations were detected by next generation sequencing (NGS). The induction therapy was given with oral retinoic acid+ intravenous infusion of arsenic trioxide, followed by 3 courses of retinoic acid+ arsenic trioxide consolidation therapy.
Results:
The G-banding karyotypic analysis demonstrated 46, XX, t(2;17;15) (q31;q21;q22)[8]/46, XX[2]. FISH results indicated that 62.0% of analyzed cells were positive for the PML-RARα fusion gene. RT-PCR further revealed the positive PML-RARα fusion gene transcript. NGS detection of gene mutations showed no obvious abnormalities. After 39 days of induction therapy with retinoic acid and arsenic trioxide, the patient achieved complete remission (CR). The karyotype was 46XX[20], and PML-RARα/ABL was 0/100. Then, the patient was treated with 3 courses of consolidation therapy, and the results remained in CR.
Conclusions
APL with complex t(2;17;15) (q31;q21;q22) is rare, and the morphological characteristics are not typical, but it is still associated with the formation of PML-RARα fusion gene. Retinoic acid+ arsenic trioxide has a good therapeutic effect, and the long-term efficacy still needs follow-up.
