Objective To review our experiences of diagnostic methods and surgical treatment of the left superior vena cava (LSVC) draining into the left atrium.Methods Nineteen patients with LSVC draining into the left atrium were diagnosed and treated surgically from February 1998 to January 2012.All the cases were combined with other congenital heart diseases including patent ductus arteriosus,ventricular septal defect,atrial septal defect,single atrium,triatriatum,partial endocardial cushion defect,anomalous pulmonary venous drainage,right ventricle outflow stenosis,pulmonary valve stenosis,tetralogy of Fallot,double outlet right ventricle,complete endocardial cushion defect,tricuspid atresia.The patients were diagnosed through different methods including echocartiographic examination,cardiac catheterization,computer tomography,and explored during the operation,even postoperatively.All were treated surgically with four techniques including simple ligation to the LSVC,including ligation during a redo procedure; intra atrial rerouting to drainage the flow from the LSVC to the right atrium,atrial septum reconstruction to make the outlet of the LSVC lying in the right side of the patched atrial septal,and bidirectional Glenn shunt to get a physiological result.Results No mortality postoperatively.All the cases were uneventful postoperatively.And the main postoperative course was related only to the main diagnosis of congenital heart disease,not to the left superior vena cava draining into the left atrium.The echo examination result was satisfied before the discharge.The early and long term follow-up(1-11 years) results are excellent,no arrhythmia,no cardiac deficits after echo examination,including stenosis obstruction and residual shunt.No death.Conclusion The diagnostic methods of the LSVC draining into the left atrium are difficult,the only way to make the diagnosis clearly enough before the operation is depending on improving of more and more comprehending to this rare cardiac anomaly,by the pediatric cardiologists,the sinologist,the intensive care unit,and the pediatric cardiae surgeons.The choice of different surgical treatment is depending on the diagnosis and the findings during the operations,and the results are excellent after a suitable choice made.

Objective To explore the feasibility and application of determining the center of the inferior portion of the glenoid on a standard anteroposterior view of the normal glenoid. Methods Seventy shoulders of 35 mature adults were measured in this study. A 64-slice CT 3D reconstruction was performed for each glenoid. A standard anteroposterior view and the scale of glenoid were made at a 3D workstation by one radiologist, and then transferred to software AutoCAD as 2D images. The 2D images were analyzed with AutoCAD respectively by 3 radiologists. The line was drawn between the most anterior and the most inferior points of the glenoid bony rim. On the same image, another line was drawn between the most posterior and the most inferior points of the glenoid bony rim. Two perpendicular bisectors of the 2 lines were drawn. The cross point of the 2 perpendicular bisectors was regarded as the circle center of the inferior part of the glenoid. The distances from the circle center to the anteroinferior and the posteroinferoir rims of the glenoid and the most posterior point were measured. Measurements were expressed as the mean ± standard deviation. Several related samples Friedman rank sum test was used to compare the measurements (the distance from the circle center to the most posterior point) by the 3 radiologists. Paired t tests were used to compare the differences between the left and right glenoids. Results The mean distance from the circle center to the most posterior point was ( 14. 1 ± 1.6) mm, the anteroinferior rim was ( 14. 0 ± 1.7) mm, and the posteroinferoir rim was ( 14. 1 ±1.6) mm. No significant differences were found ( P>0. 05) between measurements by the 3 radiologists. No significant differences were found ( P>0. 05) between the measurements of the both-side glenoids. Conclusions The method of determining the center of the inferior portion of the glenoid based on the most anterior,posterior and inferior points of the glenoid on a standard 3D anteroinferior view of the normal glenoid is easy,practical and highly repeatable. The radius of the left glenoid is comparable to the radius of the right side in normal shoulders. This method can be used to quantify a glenoid bone defect precisely.

OBJECTIVETo evaluate the long-term outcomes of weight loss and the cause of high rate of loss to follow-up after laparoscopic adjustable gastric banding (LAGB) in obese patients.

METHODSClinical and follow-up data of 226 obese patients undergoing LAGB operation in the Changhai Hospital from June 2003 to June 2007 were analyzed retrospectively.

RESULTSA total of 125 patients were followed up for 3-7 years. Among these 125 cases, 115 (92.0%) presented weight loss after LAGB, 60 (48.0%) presented extra weight loss after LAGB. Another 105 cases (44.7%) were lost to follow-up. Most of patients who were loss to follow-up were younger (P<0.05). Gender, weight and BMI were not associated with the rate of loss to follow-up (all P>0.05).

CONCLUSIONSLaparoscopic adjustable gastric band surgery is a relatively simple and safe procedure among the bariatric surgery, but the follow-up protocol is complex and the rate of loss to follow-up is high. Postoperative follow-up should be emphasized.

OBJECTIVETo observe the effect of Jianpi Bushen Qingchang Huashi Recipe (JBQHR) on proliferation and migration of bone marrow mesenchymal stem cells (BMSCs).

METHODSBMSCs were isolated and cultured in vitro with adherence screening method to prepare cell suspension. No drug intervention was given to BMSCs in the vehicle control group. JBQHR at 0.39, 0.78, 1.56 µg/mL was added in BMSCs of low, mid, and high dose JBQHR groups for co-incubation. Its effect on the proliferation of BMSCs was detected by CCK-8. BMSCs migration and chemotactic ability was detected using Transwell method. Each dose JBQHR combined ERK kinase inhibitor U0126 was set up as control. The phosphorylation of extracellular regulated protein kinase (ERK) and CAMP responsive element-binding protein (CREB) were detected by Western blot.

RESULTSCompared with the vehicle control group, the proliferation of BMSCs and BMSCs migration number could be promoted in the 3 JBQHR groups (P < 0.05). Besides, the proliferation of BMSCs was better in mid and high dose JBQHR groups than in the low dose JBQHR group (P < 0.05). Compared with the vehicle control group, the phosphorylation of ERK and CREB could be elevated in the 3 JBQHR groups (P < 0.05), and could be inhibited by U0126 (P < 0.01). Compared with the low dose JBQHR group, the phosphorylation of ERK increased in mid and high dose JBQHR groups with statistical difference (P < 0.05).

CONCLUSIONJBQHR could promote the proliferation and migration of BMSCs, and its mechanism might be related to ERK/CREB signaling pathway

Results There were 48 patients accompanied with MODS(90.6%),and among them,35 patients died in hospital(66.0%).All the 10 patients with CPR interval ≥6min were accompanied with MODS and they died in hospital.There were 43 patients who underwent CA immediately and of them,38 patients were accompanied with MODS.The incidence and mortality of MODS in the patients with CA-ROSC interval 0.05).Conclusion The risk factors such as ROSC interval ≥6 min,AC-ROSC interval ≥10min and the SIRS after ROSC are significantly associated with the incidence of MODS.The organic function of the patients should be evaluated promptly.

The study was aimed to investigate the possible effects of 8-chloroadenosine 3', 5'-monophosphate (8-Cl-cAMP) on the multiple myeloma cells. The multiple myeloma cell line RPMI8226 was used as in vitro models. The effect on growth inhibition of RPMI8226 cells was evaluated by cell growth and viability curve. DNA fragment was visualized by agarose gel electrophoresis. The amount of apoptosis cells was measured by flow cytometry. Meanwhile Western blot assay were used to detect the change of several key cell cycle regulatory proteins CDK2 and cyclin E in these cells before and after the treatment. The results showed that low dose 8-Cl-cAMP (1-30 micromol/L) inhibited the proliferation and viability of RPMI8226 cells significantly. Agarose gel electrophoresis of DNA revealed the apoptosis characteristic "ladder" pattern. Apoptosis was also confirmed by flow cytometry. In addition, 8-Cl-cAMP was able to inhibit the cell growth through modulating expression of cell cycle regulators CDK2 and cyclin E. It is concluded that 8-cl-cAMP inhibits the proliferation and induce apoptosis of multiple myeloma cells effectively.

This study was aimed to investigate the incidence of JAK2V617F mutation in BCR-ABL negative patients with myeloproliferative disorders (MPD) and its relation with clinical characteristics of MPD. The sensitive and specific test for JAK2V617F mutation was established for improving diagnosis level in Gansu province. 47 BCR/ABL negative MPD patients and 12 healthy people were enrolled in this study. Allele specific polymerase chain reaction (AS-PCR) was used to amplify the exon 12 of JAK2 gene which harbours V617F mutation. The PCR products were identified by DNA sequencing. And its relation with clinical characteristics of MPD was analyzed also. The results indicated that the incidence of JAK2V617F positive mutation in 47 patients with BCR-ABL negative MPD was 74.5 % (35/47), including 83.9 %(26/31) in patients with polycythemia vera (PV), 60 % (9/15) in patients with essential thrombocythemia (ET), only in one patient with idiopathic myelofibrosis (IMF). In PV group, the patients with JAK2V617F positive mutation had higher counts of WBC and Plt than patients with JAK2V617F negative mutation. In ET group, the patients with JAK2V617F positive mutation had higher WBC count and Hb level than those in the patients with JAK2V617F negative mutation with tendency of suffering from complications such as hepatosplenomegaly, haemorrhage and thrombosis. It is concluded that JAK2V617F mutation is more frequent in BCR-ABL negative patients with MPD, the AS-PCR method is sensitive and specific for detection of the mutation and may successfully use in clinical examination.
