Objective To investigate the role of CT three-dimensional reconstruction (3D-CT) in the diagnosis of bronchial foreign body.Methods Thirty-seven suspected pediatric cases of bronchial foreign bodies underwent CT scanning and 3D-CT reconstruction,whose accuracy was defined by bronchoscopical or surgical findings.Results For all the 37 cases,chest X-ray showed 8 cases (group A) had bronchial foreign body,while 29 cases(group B) were negative.In group A,CT findings suggested lung infection in 5 cases,congenital pulmonary dysplasia-lung lobe absence in 2 cases and tracheo-esophageal fistula in 1 case.In group B (29 patients),25 cases with bronchial foreign bodies were suspected by CT scanning and further bronchoscopical examination confirmed the existence of 24 cases of vegetable foreign body,one case of the tracheal tumor.For the four cases with negative result of bronchial foreign bodies after CT scanning,lung infection and laryngitis were confirmed in two cases respectively.Among the 24 surgically-confirmed cases of vegetable foreign bodies,CT scanning showed tracheobronchial foreign body in fourteen positive results,irregular tracheal stenosis in six cases and obstructive atelectasis,emphysema,pneumonia in seven each.Tracheobronchial foreign body and irregular tracheal stenosis were direct signs,accounting for 74%(20/27).Obstructive atelectasis,emphysema and pneumonia were indirect signs,accounting for 26%(7/27).Conclusion 3D-CT plays an important role in diagnosis and differential diagnosis of bronchial foreign body.

Objective According to the level of serum cystatin C (Cys-C)in patients with multiple myeloma (MM),to explore its significance of early assessment to renal damage.Methods To select 42 patients with MM(MM group) and 30 healthy subjects(control group),and measure serum Cys-C,creatinine (SCr) and β2-microglobulin (β2-MG).Results The level of serum Cys-C in MM group was significantly higher than that in control group [(2.34 ± 0.57) mg/L vs.(0.66 ± 0.12) mg/L],which increased with ISS stage[Ⅰ,Ⅱ,Ⅲ stage was(1.77 ± 0.38),(2.11 ± 0.46),(3.14-± 1.07) mg/L](P＜ 0.05).Cys-C and β 2-MG,renal function had a positive correlation (r =0.760,0.694,P ＜ 0.05).Conclusion The increasing of Cys-C in MM patients is related to impaired renal function and tumor burden,which can be used as an early assessment indicators.

With the rapid increase of the number of cardiovascular disease patients in China, and the popular trend of cardiovascular disease risk factors is becoming more and more obvious, the control of risk factors for cardiovascular disease has become an important public health problem as well as a great challenge to social and economic development. Recent studies show that resistance training plays a positive impact on the control of risk factors for cardiovascular disease. This article reviewed the related literature in recent years for the resistance training control risk factors of the cardiovascular disease, and stated the precautions and challenges during the process of the implementation of resistance training in order to provide new clues to the research and practice for control the risk factors of cardiovascular disease .

Vertebral artery hypoplasia is a congenital vessel variation. Its incidence is from 1. 9 to 26. 5% . In recent years, studies have shown that vertebral artery hypoplasia may be a potential risk factor for posterior circulation infarction, especialy when it coexists with other cerebrovascular risk factors. Vertebral artery hypoplasia may also cause regional hypoperfusion and complex neurovascular regulation, and it also has a certaln link with migralne.

Objective To investigate effect of continuous veno-venous hemofiltration on treatment of children with acute re-spiratory distress syndrome .Methods A total of 84 cases of children with acute respiratory distress syndrome were divided into control group (n= 42) and observation group (n = 42) .Control group was given conventional therapy including etiological treat-ment ,mechanical ventilation ,fluid management and anti-inflammatory treatment .Besides conventional therapy similar to control group ,observation group was administrated continuous veno-venous hemofiltration .Gender ,age ,admission critical illness score (PICS) ,clinical manifestations ,blood gas indexes (PaO2 ,SaO2 ) and oxygenation index (OI = PaO2 /FiO2 ) before and after treat-ment ,duration of mechanical ventilation ,pediatric intensive care unit (ICU) hospitalization days and mortality in above two groups were analyzed retrospectively .Results There were not significant difference in gender ,age and admission critical illness score (PICS) of two groups(P> 0 .05) .PaO2 ,SaO2 and OI of observation group were higher than that of control group in the third and fifth day after treatment (P < 0 .05) .The average ICU hospitalization day of observation group was shorter than that of control group (P< 0 .05) .Mortality of observation group was lowered compared with control group (P< 0 .05) .Conclusion Veno-venous hemofiltration could effectively reduce duration of mechanical ventilation and mortality in treatment of children with acute respirato -ry distress syndrome ,which is worth clinical popularization .

Myasthenia gravis is a autoimmune neuromuscular disorder characterized by weakness and fatigability of skeletal muscles. The underlying defect is a decrease in the number of available acetylcholine receptors at neuromuscular junction due to an antibody-mediated autoimmune attacks. The course of myasthenia gravis during pregnancy is not predictable. We experienced a patient of myasthenia gravis associated with pregnancy who underwent cesarean section and transient neonatal myasthenia gravis of the newborn. We present this case with brief review of the concerned literatures.

Primary ovarian pregnancy is comparatively rare in ectopic pregnancy. Ovarian pregnancy occurs in corpus luteum cyst and is usually accompanied with the rupture of ovary and a massive hemoperitoneum. It presents as a hemorrhagic ovary and frequently misdiagnosed as a ruptured corpus luteum. Spiegelberg's criteria should be fulfilled for the diagnosis of ovarian pregnancy. Two cases of ovarian pregnancy were presented with a brief review of the literatures.

Objective To observe the effect of JWSNS serum on proliferation and apoptosis hepatic stellate cells.Methods After being added different concentrations of JWSNS (the low concentrations of JWSNS:0.78 g/ml of crude drug; the medium concentration group of JWSNS:1.56 g/ml of crude drug; the high concentration group of JWSNS:3.12 g/ml of crude drug) drug-containing serum in vitro HSC-T6 cells for 12h,24 h and 48 h respectively,detected serum HSC-T6 proliferation with MTT colorimetry method and measured HSC-T6 apoptosis with flow cytometry and TUNEL method.Results (①) After applied JWSNS on rats HSC-T6,the Cell proliferation was inhibited which showed a time-concentration dependence.The differences were significant when comparing each JWSNS group with the control group (P＜0.01).High concentration of JWSNS group showed significant difference when compared with Biejiaruangan tablets group (P＜0.05) with high concentration of JWSNS (0.399± 0.041) ％ after 48h,and Biejia-Ruangan tablets (0.429± 0.037) ％ after 48 h.② Flow cytometry analysis showed each JWSNS group and Biejiaruangan tablets group had significant increased cell apoptosis when compared with the control group (P＜0.05) after 12 h,24 h,and 48 h.JWSNS medium concentration group [12 h was (17.83±0.25)％,24 h was (26.06±0.26)％,48 h was (39.30±2.25) ％] and JWSNS high concentration group [12 h was (27.15±0.29)％,24 h was (38.96±0.51)％,48 h was (49.34± 0.77) ％] had a significant increased cell apoptosis compared to the Biejia-Ruangan tablets group [ 12 h was (8.31 ± 0.30) ％,24 h was (16.25 ± 0.25) ％,48 h was (27.12± 0.39) ％].③ TUNEL detection showed that each concentration of JWSNS group [the low concentration of JWSNS:was (25.1 ± 1.48)％,medium concentration group of JWSNS was(39.30±2.25)％,high concentration group of JWSNS was(39.30±2.25)％] had a significant increased cell apoptosis rate than Biejiaruangan tablets group (30.0± 3.92) after 48 h (P＜0.01).Conclusion JWSNS containing serum can inhibit the proliferation of HSC-T6 in vitro,promote the apoptosis
