This article was aimed to study the immunomodulatory effect of ethanol sediments of the seeds of Descurainia sophia(L.) Webb. ex Prantl. both in vitro and in vivo. The lymphocyte proliferation test in vitro was carried out to explore the effect of the ethanol sediments on the proliferation of T cell and B cell in the spleen of normal mice. And, the carbon clearance test, serum hemolysin test, and delayed-type hypersensitivity test were used to investigate the influence of fraction on non-specific immunity, humoral immunity and cellular immunity in the immunosuppressive mice induced by cyclophosphamide. Besides, the immunosuppressive model was used to evaluate the effect of fraction on immune organs and content of cellular factors in blood serum. The results showed that the ethanol sediments promoted Concanavalin A (Con A) induced T cell and Lipopolysaccharides (LPS) induced B cell (P < 0.01). It increased the carbon clearance index K, phagocytic index α, half value hemolysis (HC50), and swelling degree of auricula (P < 0.05 or P < 0.01). It reduced the body weight and atrophy of thymus and spleen index (P < 0.05 or P < 0.01). It increased the contents of IL-2, IFN-γ and IL-4 in serum in immunosuppressive mice (P < 0.05 or P < 0.01). It was concluded that ethanol sediments of the seeds of D. sophia(L.) Webb. ex Prantl. can boost the lymphocyte proliferation, protect the immune organs, and enhance the non-specific and specific immunity in immunosuppressive mice, which indicated that it had immune-promotion effect.

Cerebral venous and sinus Thrombosis (CVST) is a rare ischemic cerebrovascular disease,the lesions of 60% patients are involved in multiple venous sinus,of which the superior sagittal sinus thrombosis is most common.The pathogenesis and pathophysiology of CVST has not yet been fully elucidated,and the establishment of stable and ideal animal models can provide a basis for the study of its development,prognosis and efficacy assessment.This article summarizes the characteristics and advantages of several available CVST models,but each method has its own limitations.Therefore,the establishment of a more ideal animal model will help to fully understand the pathogenesis and pathological process of CVST.

Objective To purify native and recombinant heparin-binding hemagglutinin(HBHA)protein,and investigate the activity of HBHA polyclonal antibody against aggregation of Bacillus CalmetteGuerin(BCG)induced by HBHA.Methods After growing BCG to the stationary phase in the 7H9 liquid medium,the native HBHA protein(nHBHA)was obtained by CL-6B column chromatography.At the same time,the HBHA gene fragment was cloned and expressed by transforming Escherichia coli BL-21.Then the polyclonal antibody against rHBHA was prepared by immunizing rabbit.Different comcentration of the HBHA protein was added to the BCG liquid medium,and the aggregation of the BCG was observed.Then,add the HBHA protein that incubated with anti-HBHA antibodies to the BCG culture medium and observe the aggregation of BCG.Results The purity of native HBHA was 99% and the concentration was 1.016 mg/ml.The expressed product contained 36% of total somtic protein.After purified,the purity of the recombinant HBHA protein was 97.1% and the concentration was 10.98 mg/ml.Both the rHBHA and nHBHA could induce the aggregation of BCG.When then concentration of nHBHA is 0.2μg/ml,BCG could be induced to aggregate,while the rHBHA concentration is 2μg/ml could induce the aggregation.Both aggregations could be suppressed by the polyclonal antibody against rHBHA.Conclusions The native and recombinant HBHA are successfully obtained.It is proved that the rHBHA could induce the aggregation of BCG similar as nHBHA,and polyclonal antibody against rHBHA could also suppress the activity of nHBHA.It suggested that rHBHA could be further used in clinical diagnosis and vaccination.

Objective To summarize the clinical experience of segmental living related liver transplantation for very small infant with biliary atresia. Methods The recipient was a 145-day-old male with congenital biliary atresia. The infant was 66 cm in height and weighed 3.08 kg. The donor was his 36-year-old mother. Her segment Ⅱ of the liver was excised and orthotopically transplanted into the infant's body as the graft. The portal vein of the graft was end-to-end anastomosed to the portal vein of the recipient, the hepatic artery of the graft was end-to-end anastomosed to the proper hepatic artery of the recipient with lateral superficial vein of left great saphenous vein from donor as a bridge, and the hepatic vein was end-to-end anastomosed to the hepatic vein of the recipient whose hepatic vein was conformed from right, middle and left hepatic vein. Biliary tract was reconstructed via Roux-en-Y operation. Results Segment Ⅱ (160 g) of liver from donor was resected, and there was no blood infusion. The donor retained her liver function within 5 days and was discharged on the eighth day. The operating time of graft implantation was 451 min. The blood loss was 250 ml. Non-liver stage was 71 min. The cold ischemic time was 132 min. Cyclosporine, mycophenolate mofetil (MMF) and prednisone were used for postoperative immunosuppression. The bilirubin level of the infant was decreased to the normal level one week after operation, and the liver function became normal in 9 days. Jejuno-leakage on the 7th day after the transplantation was recovered by mend and drainage and discharged on the 35th day. The donor and recipient were in satisfactory condition to present. Conclusion The segmental living related liver transplantation is advisable for very small infant with biliary atresia. Perfect operative technique and postoperative intensive care are the keys to ensure the success of the procedure.

Objective To investigate the cause of jejunum perforation after infantile livingrelated liver transplantation (ILRLT) and summarize the experience of treatment. Methods The clinical data of 28 infants with biliary atresia who underwent ILRLT were analyzed and 4 of 28 infantile recipients (14. 3%) developed jejunum perforation after ILDLT. Results Four patients had 7 episodes of jejunum perforation after transplantation among 28 infantile recipients who underwent ILRLT because of biliary atresia. The median time between transplantation and perforation was 11 days.Perforation occurred at the point of silk in jejunum stoma (n = 3) and the Roux-en-Y limb (n = 1 ).None had a history of prior operation including Kasai in 4 patients. Clinical manifestation included fever, increased heart rate, abdominal distention, leukocytosis, and no free air on abdominal roentgenograrns. A simple repair was performed in three infants with silk: two developed recurrent perforation (67%) and underwent a re-exploration,and another had a third perforation and underwent a third repair because of re-perforation. Another child underwent a simple repair with prolene, and there was no recurrence. None died from the perforation in our study. Conclusion The occurrence and location of jejunum perforation after ILDLT suggests that the cause of the perforation is related to the jejunal anastomosis with silk, and the jejunum perforation may be avoided in the jejunal anastomosis with prolene. Early diagnosis and exploration may ensure better survival.

Objective To summarize the clinical experience of successful liver transplantation from infant donation after cardiac death (DCD) for infant with biliary astresia (BA).Methods The donor was a 16-months-old girl with a body weight of 10 kg,who died of irreversible anoxic cerebral damage after sudden asphyxiation.The recipient was a 24-months-old girl with a body weight of 12 kg,who suffered from icteric concurrent late biliary cirrhosis after the Porta-jejunum anastomosis because of congenital BA.The DCD liver was classically orthotopically transplanted into the infants recipient.The warm ischemia time was 7 min,the cold ischemia time was 360 min,and the graft volume to the standard liver volume (GV/SLV) was 1.02.After operation,the vital signs and transplanted liver function of the recipient were monitored,and the recipient was given treatments of anti-infection,anticoagulation,and improving the microcirculation.The recipient was treated with the triple immunosuppression protocol of tacrolimus,mycophenolate and prednisone to prevent rejection.Results The operating time of the recipient was 480 min,the non-liver stage was 65 min,and the blood loss was 230 mL.The endotracheal intubation was removed from the recipient at 12 h,and the recipient started to eat at 48 h aftcr operation.The recipient had a hepatic artery thrombus on the 3rd and 15th day after operation,and the hepatic artery had re-blood-supply after the hepatic artery catheterization and continuous perfusion with urokinase.The recipient was discharged on the 42nd day,and the recipient was in satisfactory condition to present.Conclusion The infant DCD liver is a better graft for infant liver transplantation for BA.The surgical complications can be reduced with matched volume of donor-recipient liver; and it can guarantee a successful operation with perfect operative technique and careful perioperative management.

This article was aimed to study immunomodulatory effect of chemical split fractions ofMori Cortex, in order to initially explain effective parts that played a role in immunomodulatory effect ofMori Cortex. The carbon clearance test, serum hemolysin test, E-rosette test, and lymphocyte transformation test were carried out to explore influence of these chemical split fractions ofMori Cortex on immune organs, nonspecific immunity, humoral immunity and cellular immunity. The results showed that in the carbon clearance test, 50% ethanol fraction markedly reduced the thymus index (P<0.01) and the correction indexα (P<0.05). In hemolysin test, the half value hemolysis (HC50) was improved by 30% ethanol fraction and fatty oil fraction (P<0.05). Besides, in the E-rosette test, the E-rosette ration was increased in the 30% ethanol fraction group (P<0.05). In the lymphocyte transformation test, the 30% ethanol fraction can promote the thymus and spleen lymphocytes proliferation (P<0.05 orP<0.01), while the 50% ethanol fraction inhibited the proliferation (P<0.05 orP<0.01). It was concluded that the 30% ethanol fraction can boost both the humoral immunity and cellular immunity; the 50% ethanol fraction can induce the growth of thymus with a suppressive effect on nonspecific immunity and cellular immunity; the fatty oil fraction can improve humoral immunity.

Objective To explore the efficacy and safety of venous sinus stenting in the treatment of refractory idiopathic intracranial hypertension (IIH) complicated with venous sinus stenosis. Methods We reviewed our clinical database for 18 patients with resistant or fulminant IIH and cerebral venous sinus stenosis,who underwent placement of venous sinus stents between January 2013 and December 2016. Patients were considered eligible for stenting based on the following criteria: (1) medically refractory IIH;(2)papilledema confirmed by an ophthalmologist;and(3)dural venous sinus stenosis of the dominant venous outflow system with a gradient of ≥10 mmHg(1 mmHg=0.133 kPa). Prior to intervention, diagnostic angiography and venous pressure measurements were performed. Clinical follow-up was available in all patients at 6 to 48 months after stenting.Angiography to evaluate stent patency and restenosis was performed at 6 months after intervention;Relevant clinical, demographic and radiographic data were extracted after review of these records. The paired t test was used to compare the changes before and after the operation. Results The mean lumbar CSF pressure was reduced from (385±72) mmH2O(1 mmH2O=0.009 8 kPa) to (201±24)mmH2O(t=13.02,P<0.05).The mean pressure gradient across the venous stenosis was reduced from(31.5±11.4)mmHg before the procedure to(2.5±2.1)mmHg(t=10.96,P<0.05).Headache in 13 cases,vision in 14 were resolved. Papilledema and pulsatile tinnitus resolved in all patients. There was no instances of restenosis among the 18 patients with follow-up imaging.Conclusion In patients with IIH and documented evidence of venous sinus stenosis with a high pressure gradient,venous sinus senting represents an effective treatment strategy.

Portal vein thrombosis (PVT) is one of the most common complications of liver cirrhosis. Due to coagulation disorder and the risk of bleeding in liver cirrhosis, there are many controversies over the treatment of liver cirrhosis with PVT in clinical practice. Common therapies for PVT include anticoagulant therapy, intervention, and thrombolysis. This article elaborates on the current status of the treatment of liver cirrhosis with PVT, in order to provide help for the development of standard and reasonable clinical treatment strategies.
