Objective To explore the relationship between vertebrobasilar insufficiencies caused by subclavian steal syndrome and degree or type of steal phenomena.Methods 80 patients who were diagnosed subclavian steal syndrome by transcranial doppler ultrasound were analyzed retrospectively,24 cases in them were received digital subtraction angiography.The degree of steal phenomena were determined by direction of blood flow in the ipsilateral vertebral artery,and the type of steal phenomena were determined by whether basilar artery involved in steal phenomena.Finally,we made the correlation analysis between vertebrobasilar insufficiency caused by subclavian steal syndrome and degree or type of steal phenomena.Results There was a significant relationship between the severity of subclavian artery stenosis and degree of VA steal in 24 patients performed with both TCD and DSA(t =15.59,P ＜0.05).There was no significant relationship between the vertebrobasilar insufficiency and severity of steal phenomena (P ＞0.05).There were 21cases(77.8％) exist vertebrobasilar insufficiency in the patients whose basilar artery were involved in steal phenomena,and there were 18 cases(33.9％) exist ertebrobasilar insufficiency in the patients whose basilar artery were not involved in steal phenomena.There was a significant differences between the two type of steal phenomena(P ＜ 0.05).Conclusion The vertebrobasilar insufficiency caused by subclavian steal syndrome doesn't associate with the degree of steal phenomena,and associates with the type of steal phenomena.Paying close attention to whether basilar arteries are involved in steal phenomena is useful for analyzing the patient 's condition and guide clinical treatment.

Purpose To evaluate the value of systemic ultrasonography in screening fetal congenital heart malformation. Materials and Methods A total of 5224 pregnant women underwent systemic ultrasonography to check fetal organs such as head, face, spine, heart, abdomen and limbs. Color Doppler and frequency spectrum Doppler images of four-chamber view, left ventricle outflow tract view and right ventricle outflow tract view were obtained and analyzed by using four-chamber view with probe tilting craniad slightly technique. Results Eleven cases showed congenital cardiac malformations (three cases of right atrial dilatation+tricuspid regurgitation, two cases of ventricular septal defect, one case of left heart dysplasias+aortic stenosis, one case of left heart dysplasias+mitral stenosis+aortic atresia, one case of aortic stenosis, one case of Ebstein's anomaly, one case of transposition of conducting arteries, one case of tetralogy of Fallot) and 1 case misdiagnosed. Conclusion Systemic fetal ultrasonography is simple and convenient with relatively high accuracy, which can be recommended in screening for fetal heart malformation.

The incidence of cholangiocarcinoma is rising, poor prognosis due to lack of viable treatment.Recent investigations into the underlying molecular mechanisms of cholangiocarcinogenesis and tumor growth have contributed greatly to our understanding of this disease, which will lead to the identification of therapeutic targets for this devastating cancer. The purpose of the following review is to address what has been learned over the past decade concerning the molecular basis of cholangiocarcinogenesis and factors regulating cholangiocarcinoma growth. Through a better understanding of these mechanisms, more specific diagnostic, therapeutic, and preventative strategies may be developed and hopefully improve the outcome of this devastating disease.

OBJECTIVE:To observe the efficacy and safety of low-dose Progesterone injection combined with Baotai wuyou capsule in the treatment of threatened abortion. METHODS:107 patients with threatened abortion were retrospectively analyzed and divided into observation group(54 cases)and control group(53 cases)by different medication. All patients received bed rest orally taking folic acid and other measures. Meanwhile,control group was given Progesterone injection 20-40 mg,qd,intramuscu-larly injected. Observation group was given Progesterone injection 10-20 mg,qd,intramuscularly injected and given 4 Baotai wuy-ou capsule additionally,tid,taking with ginger decoction,no fish during the medication. The courses of 2 groups were 14 d. Clini-cal efficacy,hemostatic time,remission time of abdominal pain and backache in 2 groups were observed,and the incidence of ad-verse reactions during the treatment was recorded. RESULTS:The total effective rate in observation group was significantly higher than control group,hemostatic time,remission time of abdominal pain and backache were significantly shorter than control group, the incidence of adverse reactions was significantly lower than control group,with statistical significances (P<0.05). CONCLU-SIONS:Low-dose Progesterone injection combined with Baotai wuyou capsule shows good efficacy in the treatment of threatened abortion,which can shorten patients'hemostatic time,remission time of abdominal pain and backache,and reduce the incidence of adverse reactions,with good safety.

Objective To observe the incidence of acute radiation pneumonitis (RP)after intensity modulated radiation therapy,and to explore the relationship between the incidence of RP and the parameters from dose-volume histogram (DVH)in the patients with non-small cell lung cancer (NSCLC).Methods By Pinnacle 7.6c TPS, 46 patients with NSCLC were treated by IMRT.The values of the percentages of the lung volumes receieved 5, 10,20,and 30 Gy radition to the total lung volumes (V5 ,V10 ,V20 ,V30 )and mean lung dose (MLD)were observed,and its correlation with acute RP was analyzed.Results The incidence of acute RP of the patients with NSCLC was 37.0% (17/46),among then there were 29 cases (63.0%)of Grade 0 (non-pneumonitis group), 12 cases (26.1%)of Grade 1,5 cases (10.9%)of Grade 2,and there were no Grade 4 and 5 RP.The values of V5,V10,V20,V30,and MLD of lung were 53.34 %,43.12%,24.15%,15.36 %,and 16.02 Gy.The values of V5,V10,V20,V30,and MLD in pneumonitis group were 57.81%,48.91%,31.34%,17.83%, 21.71 Gy,and they were 49. 81%,39.78%,21.82%,13.12%,and 13.71 Gy in non-pneumonitis group, there were significant differences between two groups (P<0.05).Conclusion The intensity modulated radiation therapy in treatment of NSCLC can protect the lung tissue,and the parameters of DVH such as V5 ,V10 ,V20 , V30 and MLD can predict the occurrence of RP.

Energy metabolism refers to the metabolism of three major nutrients associated with the process of energy production and usage.The metabolism in patients with tumors manifests specifically, as a result of tumor-bearing state, host's response to tumor and anti-neoplastic therapy.It is believed that resting energy expenditure increases in patients with newly diagnosed tumors, which is related to C-reactive protein and release of inflammatory cytokines. After eflfectjve therapy,resting energy expenditure decreases in some degree.In addition,the stage and differentiation of tumors also affect metabolism.However,there are some conflicts among research findings.The characteristics of energy metabolism and influential factors in patients with tumors are reviewed in this paper.
