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.

Objective To study the effect of praziquantel on cells within sehistosomal ovum granuloma in the lung of mice.Methods Forty-eight mice were divided into 4 groups.Group A:first,the mice were injected with sehistosomal ova hypodermically in abdomen,and 10 days later,injected with schistosomal ova intravenously in the cauda;Group B:in addition to the injection of schistosomal ova as the same of Group A,the mice were administered with praziquantel[300 mg/(kg·d)]for 3 days,one day before the intravenous injection of the ova;Group C:in addition to the injection of schistosomal ova as the same of Group A,the mice were administered with praziquantel(75 mg/kg,B.i.d.) for 5 days weekly until the mice were sacrificed;Group D:the same as Group C but praziquantel was given to the mice from the 29th after the intravenous injection of the ova.Three mice of each group were sacrificed on the 7th,14th,28th,56th day after the intravenous injection of the ova and the lung tissues were fixed with formalin and the slices were HE stained.Twenty-five to thirty pieces of schistosomal ovum granuloma were examined and the neutrophilic granulocytes,eosinocytes,lymphocytes,fibroblasts and macrophages within the ovum granulomas were counted and the mean numbers of them of each group were calculated and compared.Results Compared with Group A,the mean numbers of neutrophilic granulocytes,eosinocytes and macrophages within the ovum granulomas were decreased significantly,and the extend of the increase of fibroblasts reduced significantly in the three groups administered with praziquantel,and especially in Group C.On the 56th day after the intravenous injection of the ova,the mean numbers of neutrophilic granulocytes,eosinocytes and macrophages decreased by 54.4%、87.0% and 23.1%,and the extend of the increase of fibroblasts reduce by 59.4%,respectively in Group C,compared with Group A.The numbers of lymphocytes did not change very much in 4 groups.Conclusion Praziquantel can restrain inflammatory cells and the hyperplasia of fibroblasts within schistosomal ovum granulomas.

Amphiregulin is the ligand of epidermal growth factor receptor.It's widely expressed in many tissues and is involved in the oncogenesis,progression and metastasis of tumors.In the clinical study of lung caner,amphiregulin is a prognostic marker for NSCLC patients.Furthermore,amphiregulin is closely associated with the sensitivity and resistance of EGFRTKI treatment.Medicine target on amphiregulin can inhibit the activity of tumors.

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 study the changes of serum interleukin-8 (IL-8) and interleukin-10 (IL-10) in preterm infants delivered from mothers with chorioamnionitis (CA) and the possible effects on bronchopuhmonary dysplasia (BPD) and brain injury of preterm infants.Method From October 2014 to October 2015,clinical data from mothers without clinical manifestations of CA giving birth to a preterm baby (gestational age:26 to 33 weeks) were collected in Changzhou Maternal and Child Health Hospital and Suzhou Municipal Hospital.The infants were assigned to CA group and non-CA group according to their mother's placenta pathology.The levels of serum IL-8 and IL-10 were measured using enzyme-linked immunosorbent assay (ELISA) on day 1 and day 7,while the levels of WBC,CRP and PCT were measured at birth.The incidences of BPD and brain injury were also reviewed.Result A total of 67 preterm infants were included,with 51 in the CA group and 16 non-CA group.The levels of IL-8 were significantly higher in the CA group than the non-CA group on both day 1 and day 7 [(21.6 ±9.7) ng/L vs.(7.3 ±2.3) ng/L,(26.6 ± 12.9) ng/L vs.(7.3 ± 2.1) ng/L].The IL-10 levels were significantly lower on day 1 [(1.92±0.17) ng/Lvs.(2.04±0.18) ng/L] and higher on day 7 [(2.42±0.60) ng/L vs.(2.03 ±0.18) ng/L] in the CA group.Significant differences existed on the incidences of BPD (54.9％ vs.25.0％) and brain injury (74.5％ vs.43.8％) between the two groups (P ＜ 0.05).The levels of CRP and PCT were higher in CA group (P ＜ 0.05) and the WBC was similar between the two groups (P ＞ 0.05).In CA group,on both day 1 and day 7,infants with BPD had similar IL-8 and IL-10 levels comparing with infants without BPD(P ＞ 0.05),also were infants with brain injury comparing with infants without brain injury.Conclusion Chorioamnionitis in pregnant women may affect serum cytokines levels in premature infants and lead to high incidences of BPD and brain injury.

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 understand the baseline data of mortality from malignant tumor from 2006 to 2009 around Hongyanhe Nuclear Power Plant in Wafangdian City,Liaoning Province,so as to provide scientific basis for evaluating the impact of normal operation of nuclear power plant on the health of the residents nearby.Methods Thirty small towns near Hongyanhe Nuclear Power Plant were divided into 5 investigated areas according to the distances away therefrom(0.,10.,20-,30-,and 40-km).The data about from malignant tumor were obtained from the Center for Disease Control and Prevention of Wafangdian.The mortality distribution of difierent malignant tumors was analyzed,including the radiosensitive malignant tumors,especially leukemia,breast cancer,and thyroid gland cancer in different area,gender,and age groups.Results The mortality from malignant tumor was 151.97/105,and the standardized mortality rate(SMR)was 97.76/105.The mortality from malignant tumor among the males was 188.28/105(with the SMR of 116.76/105),and that among the females was 113.47/105(with the SMR of 75.89/105).with a sex ratio of 1.71.The first five cancers in the rank of death causes were lung,liver,stomach,colorectal,and esophageal cancers with mortality of 46.19/105,23.51/105,20.30/105,8.06/105 and 5.45/105,respectively.The mortality from mal.ignant tumor in the areas around the nuclear power plant from the near to the distant were 99.85/105, 137.40/105,138.73/105,156.30/105,and 154.16/105,respectively.The mortality from radiosensitive malignant tumors,leukemia,breast cancer,and thyroid gland cancer were 4.57/105,4.06/105,and 0.26/105,respectively.Conclusions Lung cancer and digestive tract malignant tumors are the main causes of death from malignant tumors in Wafangdian area before the nuclear power plant began to operate.There are no significant differences in the mortality distribution of malignant tumors among different areas,genders,and age groups.There are not significant differences in the mortality distribution of leukemia and breast cancer among different areas and age groups.

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.
