1?g/ml)could inhibit osteoblasts to grow and proliferate, and showed cytotoxic activity. Conclusion aFGF possesses the effect of triggering osteoblasts to grow and proliferate, and its effective concentration is 10-100 ng/ml.

Objective To explore ultrasonographic characteristics and prognosis of cesarean scar pregnancy in the ultrasound.Methods To conducted a retrospective study of 8 cases of diagnoses of cesarean scar pregnancy in ultrasound in our hospital from January 2013 to August 2015.All cases had ultrasonographic examinations regularly during the pregnancy and were confirmed placenta increta by cesarean section or prenatal MRI (6 cases).The imaging characteristics of 8 cases of pregnant women in early pregnancy by transvaginal ultrasound,and the positions of gestational sac and chorion frondosum were observed.Ultrasonic follow-up results,numbers of cesarean delivery,final diagnosis,and pregnancy outcome were analyzed.Results Eight cases of patients were diagnosed cesarean scar pregnancy,and all of ceses were diagnosed placenta increta by ultrasound from 11 weeks to 24 weeks of gestation.It was found that the positions of chorion frondosum were located in the lower edge of gestational sac in Two-dimensional ultrasound and the chorion frondosum was covered in cesarean section scar.The echoes of proliferous chorion frondosum were stronger than the rest of chorion leve and decidua reflexa,and the thickness of proliferous chorion frondosum were thicker than the rest of chorion leve and decidua reflexa.In the follow-up ultrasound of 8 cases in the second trimester,the original position of chorion frondosum which covered and the position of placenta were roughly similar.The position of placenta did not move up with the gestational weeks,in addition,appeared as placenta previa and covered in cesarean section scar.Five patients had strong childbearing willing of continue to conceive,one case of which needed hysterectomy,four of which underwent cesarean section delivery with alive births after using bilateral iliac arteries balloon occlusion.The rest 3 cases underwent induction of labor after using bilateral iliac arteries balloon cclusion.Conclusions Cesarean scar pregnancy in first pregnancy may be develop as placenta accreta in second and third trimester pregnancy.If chorion frondosum was observed to cover cesarean section scar by ultrasound in early pregnancy,scar pregnancy diagnosis was established.Pregnant women who have strong willing to continue their pregnancy should be pay more attentin to thiers placenta previa and placenta percreta in second and third trimester pregnancy.Close follow-up are needed.

Objective To investigate the effect of valsartan on vascular endothelial function and brachial-ankle pulse wave velocity(baPWV)in patients with essential hypertension(EH).Methods Blood pressure,NO value and brachial-ankle pulse wave velocity were determined and analyzed in 30 patients with essential hypertension before and after therapy of valsartan.Results Both blood pressure and brachial-ankle pulse wave velocity wefe re-duced greafly(P<0.05 and P<0.01),while serum NO increased significantly(P<0.01)following valsartan thera-Py,and brachial-ankle pulse wave velocity was well correlated to serum NO(r=-0.71,P<0.01).Conclusions Valsartan is not onlv effective in the control of blood pressure,but also effective in reveming the impaired endothelial function and artery elasticity in patients with essential hypertension,at the same time brachial-ankle pulse wave ve-locity is also good surrogate of endlothelial functional improvement induced by Valsartan therapy.

Objective To evaluate the effects of limb ischemic preconditioning (LIP) on the intestinal injury during release of hepatic portal occlusion (RHPO) in rats.Methods Thirty-six male Sprague-Dawley rats,aged 6-7 weeks,weighing 200-250 g,were randomly divided into 3 groups using a random number table:sham operation group (group S,n =12),RHPO group (n =39) and LIP+ RHPO group (n =20).Hepatic ischemia/ reperfusion was produced by occluding portal vein and hepatic artery for 30 min followed by 6 h reperfusion according to Pringle's method.LIP was produced by tourniquet occlusion of the right femoral artery and vein for 10 min followed by 24 h reperfusion before hepatic ischemia.The animals were sacrificed at 6 h after hepatic portal occlusion was released and the mucous membrane of small intestine was obtained for microscopic examination and for determination of malondialdehyde (MDA) content,superoxide dismutase (SOD) activity,myeloperoxidase (MPO)activity,total antioxidant capacity (T-AOC) and intercellular adhesion molecule-1 (ICAM-1) mRNA and protein expression.The degree of damage to intestinal mucous membrane was scored according to Chiu.Results Compared with group S,Chiu's score and levels of MDA and MPO were significantly increased,SOD activity and TAOC were decreased,and ICAM-1 mRNA and protein expression was up-regulated in group RHPO (P ＜ 0.05 or 0.01).Compared with group RHPO,Chiu's score and levels of MDA and MPO were significantly decreased,SOD activity and T-AOC were increased,and ICAM-1 mRNA expression was down-regulated in group LIP + RHPO (P ＜ 0.05).Conclusion LIP can alleviate the intestinal injury during RHPO in rats by enhancing the antioxidant function and down-regulating the expression of ICAM-1.

Objective To investigate the ultrasound characteristics of congenital cystic adenomatoid malformation (CCAM). Methods The ultrasonographic features of 21 cases of fetal CCAM confirmed by prenatal ultrasound were analyzed. And ultrasound ifndings were compared with the postnatal thoracic computed tomography (CT), surgical result and follow-up data. Results (1) Prenatal ultrasonographic ifndings:2 cases of CCAM typeⅠ(10%, 2/21), 13 cases of typeⅡ(62%, 13/21), and 6 cases of typeⅢ(28%, 6/21). Of them, 95%(20/21) lesions were located in unilateral thorax, while 5%(1/21) in bilateral thorax. CCAM was ifrst detected at 18th-25th gestational week with a median of 22nd week. The CVR was<1.6 and>1.6 in 16 (76%, 16/21) and 5 (24%, 5/21) cases respectively. After reaching the maximum volume, the size of mass remained stable in 8 cases and regressed in 13 cases with even complete remission in 5 cases. There were mediastinal shift in 19 fetuses (90%, 19/21), polyhydramnios in 6, and concomitant structural abnormalities in 3 cases such as pulmonary sequestration, diaphragmatic hernia and fetal hydrops. (2) Clinical outcomes:15 newborns were conifrmed as CCAM by CT, in which 9 cases underwent surgical resection. One case was conifrmed by autopsy. Nineteen cases showed good prognosis. Whereas 1 pregnancy with fetal hydrops was terminated, and 1 fetus with diaphragmatic hernia died after birth. Conclusions Dynamic prenatal ultrasound assessment is the key factor in prognosis prediction of fetal CCAM. CCAM without other structural abnormalities has a good outcome.

Objective:To assess the prognostic factors of World Health Organization(WHO)grade Ⅱ gliomas.Methods:A total of 146 patients diagnosed with WHO grade Ⅱ gliomas were treated at Jiangxi Province Tumor Hospital between June 1997 and April 2015,in-cluding 90 gross total resections(GTRs)and 56 partial resections.According to the 2007 WHO grading system of gliomas,there were 96 astrocytomas,30 oligodendrogliomas,and 20 oligoastrocytomas.Results:The median follow-up time was 88 months.Five-year overall survival(OS)and progression-free survival(PFS)rates were 75.7% and 60.0%,respectively,and 10-year OS and PFS rates were 57.4% and 37.8%,respectively.Univariate analysis of OS revealed statistically significant differences in age,sex,subventricular zone (SVZ) invasion, peritumoral edema, residual tumor volume, preoperative tumor size and numbers, and the extent of resection (P<0.05). Compared with astrocytoma patients, oligodendroglioma patients had better OS and PFS (P=0.040 and 0.049, respectively). Among those factors,sex,SVZ invasion,residual tumor volume,preoperative tumor numbers,and the extent of resection were like-wise significant for PFS (P<0.05). Multivariate analysis revealed that the extent of resection, SVZ invasion, and peritumoral edema were independent prognostic factors for OS(P<0.05)and the extent of resection and tumor numbers were independent prognostic fac-tors for PFS(P<0.05).Sixty patients developed recurrences,including 53 tumor bed failures and 7 intracranial disseminations.Conclu-sions:The extent of resection,SVZ invasion and peritumoral edema may be independent prognostic factors for OS in low-grade glio-mas.Postoperative radiotherapy would improve PFS for patients who underwent GTRs.The major pattern of failure was tumor bed re-currence.

This work was supported by Science and Technology Program of Health and Family Planning Commission of Jiangxi Province (No.20161106) Abstract Objective: To investigate the prognostic value of subventricular zone (SVZ) invasion in glioma patients. Methods: The clini-cal data of 175 patients with glioma diagnosed based on pathology in Jiangxi Province Cancer hospital between January 2010 and July 2015 were analyzed retrospectively. There were 59 cases of World Health Organization (WHO) gradeⅡ, 59 cases of WHO gradeⅢ, and 57 cases of WHO gradeⅣat the first diagnosis. There were 75 cases of SVZ invasion (SVZ+) and 100 cases of SVZ non-invasion (SVZ-) according to preoperative magnetic resonance imaging. The survival outcomes of both cohorts were compared using the Log-rank test. The correlation between the recurrence pattern and SVZ involvement was analyzed using Chi-square tests. Results: The me-dian follow-up time was 63 months. The 5-year overall survival (OS) and progression-free survival (PFS) rates were 42.2% and 37.5%, respectively. These were 20.9% and 15.3% in the SVZ+group, compared with 57.1% and 44.1% in the SVZ-group, respectively (P<0.001 and P<0.001, respectively). The SVZ+group had fewer cases of total resection, larger lesions (maximum diameter greater than 5.0 cm), and more cases of gradeⅣ(P<0.001, P<0.001, and P=0.018, respectively). There were 89 cases of recurrence. The total recur-rence rate was 62.7% in the SVZ+group, compared with 42.0% in the SVZ-group (P=0.007); the distant recurrence rates were 21.3% and 7.0% (P=0.004), respectively. Conclusions: SVZ invasion is a poor prognostic factor for OS and PFS in gliomas, which is positively correlated with a low total resection rate, large lesions, and gradeⅣlesions, and increases the probability of total recurrence and dis-tant recurrence.

Objective To describe the epidemic of imported infectious diseases in China between 2013 and 2016, including the kinds of infectious diseases, affected provinces, source countries and the epidemiological characteristics, and provide scientific information for the prevention and control of imported infectious diseases. Methods Data of cases of imported infectious diseases in China from 2013 to 2016 were collected from national information reporting system of infectious diseases, Microsoft Excel 2010 and SPSS 18.0 were used to conduct data cleaning and analysis. Results From 2013 to 2016, a total of 16206 imported cases of infectious diseases were reported in China. Of all the cases, 83.12%(13471 cases) were malaria cases, followed by dengue fever (2628 cases,16.22%). The majority of the imported cases were males (14522 cases, 89.61%). Most cases were aged 20-50 years. Except Zika virus disease and yellow fever, which were mainly reported before and after spring festival, other imported infectious diseases mainly occurred in summer and autumn. The epidemic in affected provinces varied with the types of infectious diseases, and Yunnan reported the largest case number of imported infectious diseases, followed by Jiangsu, Guangxi and Guangdong. The imported cases were mainly from Asian countries, such as Burma, and African countries, such as Angola, Equatorial Guinea and Ghana, which also varied with the types of infectious diseases. Conclusions We should pay more attention to imported infectious diseases and strengthen the prevention and control measures in our country. In order to reduce the incidence of imported infectious diseases, the health education should be enforced for persons who plan to travel abroad and the active surveillance should be strengthened for returned travelers.
