Clinical and pharmacological researches have been carried on traditional Chinese medicine (TCM) used in the treatment for hypertension from single Chinese raw dosage form to complex compound in recent years. It is found that TCM’s effects mainly focus on integral regulation for human being’s health. Besides depressing blood pressure, furthermore, TCM also have lots of efficacy in other aspects, such as relieving left ventricular hypertrophy (LVH), improving function of vascular endothelial cell and atherosclerosis, protecting kidney function, decreasing disability rate as well as enhancing quality of life. In a word, TCM should be used in preventing and treating hypertension as early as possible.

Methods 157 cases of postpartum women who had detected pelvic floor Ⅰ,Ⅱ muscle fiber strength and vaginal dynamic pressure were selected for the study in our hospital,and divided into the treatment group (82 cases) and the control group group(75 cases).The treatment group were observed on the basis of biofeedback combined with electri-cal stimulation therapy( use of phenix USB4 treatment) .The control group were observed on the basis of Kegel exer-cise.Two groups had treatment of bacterial vaginal disease.Results The treatment group after treatment,total effec-tive rate was 93.90%,better than that of the control group.At the same time Aa point,Ap point and POP-Q was bet-ter,Vaginal prolapse was improved,pelvic floorⅠ,Ⅱmuscle fiber strength and vaginal dynamic pressure was signifi-cantly different compared the control group (χ2 =11.19,P<0.05) .Conclusion The pelvic floor rehabilitation ther-apy can improve the pelvic floor muscle strength of postpartum women,and improve the symptoms of pelvic organ pro-lapse.There was no pain and no damage.The treatment effect is not affected by vaginitis,and which is worthy of clini-cal application.

Objective To sum up the clinical experience of liver retransplantation (ReTx).Methods All recipients were male. The average age was 50 years old (43-55). The indications included primary nonfunction (PNF) (1 case), acute rejection (1 case), chronic rejection and biliary infection (1 cases) and ischemic type billiary lesion and biliary infection (2 cases). The blood types of recipients and donors were identical. All donors were heart arrest. The immunosuppressive protocols included Zenapax and methylpredinisone (MP) and FK506. MMF was added if necessary.Results Three patients were cured. Two patients died at 8th and 10th day. One died of serious infection and failure of multiple organs and another died of heart failure. Complications included multiple organ infection (1 case) and biliary infection (1 case) and wound infection (1 case).Conclusion Liver retransplantation is an effective treatment for graft failure after liver transplantation. Proper indication and optimum operation time, intensive perioperative supervision and proper treatment were very important for improved effect of liver retransplantation.

Objective To study the molecular mechanism involved in early liver regeneration following cold ischemia after rat orthotopic liver transplantation(OLT). Methods Syngeneic(Lewis to Lewis)rat OLT with hepatic artery reconstruction was performed.Graft survival and liver regeneration following 1 h and 16 h cold ischemic injury were evaluated.Specimen were collected at predetermined intervals from 0,1,2,4,16,24,48,72 h post-reperfusion.The patterns of IL-6 and TNF-α expression,STAT3 activation,and upregulation of immediately early genes(IEGs)including c-fos,c-myc,and c-jun were determined in liver grafts with 1 h and 16 h cold ischemia times.Quantitative analysis of IL-6 at 2 h after reperfusion was performed for grafts preserved for 1 h and 16 h.Progression of hepatocyte replication was confirmed by bromodeoxyuridine(BrdU)immunohistochemistry.Positively BrdU-stained nuclei were quantitated and analyzed between the two groups at 48 h after reperfusion. Results Survival rate in the two groups was 100%.Compared to 1 h cold ischemia group,IL-6 and TNF-α expression and STAT3 activation in 16 h cold ischemia group were markedly increased.Extensive hepatocyte replication was present.Upregulation of immediate early genes of c-fos,c-myc,and c-jun was also observed.Grafts with 1 h ischemic iniury had lower levels of IL-6 than that when grafts suffering from ischemia for 16 h(t=27.7,P＜0.05).Number of positively stained nuclei in 16 h group were more than that in 1 h group at 48 h after transplantation(t=13.4,P＜0.05). Conclusions Severe cold ischemia initiated liver regeneration after rat OLT.TNF-α and IL-6 are important factors in early liver regeneration.IL-6/STA3 pathway in liver regeneration is an important part in the recovery of grafts following cold ischemia injury.

Objective To explore the feasibility and efficacy of desensitization protocol for highly sensitized renal transplant patients (HSP). Methods Thirty-five HSPs ( HLA class-Ⅰ panel reactive antibody ＞50 %), including 27 patients with a positive T and/or B cell cytotoxicity crossmatch (XM) and 8 patients with a negative T and B cell XM, received plasmapheresis plus intravenous immunoglobulin (PP-IVIG)treatment. Results The positive XM was rendered negative by PP-IVIG treatment in 25 of 27 (92.6 %)HSPs, and subsequent transplantation was performed. Two patients did not receive renal transplants due to persistent positive XM. In 25 patients receiving renal transplants, no hyperacute rejection occurred. There were 8 cases of acute rejection, including 5 cases of acute humoral rejection (AHR). All rejection episodes were reversed. During a follow-up period of 52 ± 26 months, the serum creatinine levels at 12th and 24th month were 112± 18 and 130 ± 38 mol/L respectively. The 1- and 3-year graft survival rate was 96. 0 %and 80. 0 % respectively. Conclusion The desensitization therapy by PP-IVIG is effective for HSP. High rate of AHR is the major defect of this protocol. The short-term graft survival rate after this protocol is acceptable but the long-term survival rate needs to be defined.

Objective To observe recipient survival time and liver graft regeneration in an orthotopic liver transplantation model using IL-6 knockout mice as a donor.Methods A model of liver transplantation in C57BL/6 WT and IL-6 KO mice with C57BL/6 background was established.Thirty eight mice were divided into three groups:C57BL/6 wild type→C57BL/6 wild type control group(n=10),IL-6 KO→IL-6 KO group(n=14)and IL-6 KO→C57BL/6 WT group(n=14).Hepatocyte replication with BrdU uptake after liver transplantation was examined by immunohistochemistry.Resuits The survival time in the control group was＞16 days.and that was 2 days and 1.6 days in the IL-6 KO→IL-6 KO and IL-6KO→C57BL/6 WT,respectively.The difierence in survival time in all three groups was statistically significant(F=190.09,P＜0.01).The liver grafts in control group showed minimal injury and no necrosis and mild increase of BrdU uptake at 48 hours.Patchy areas of necrosis and hepatocyte ballooning were observed in the two groups using IL-6 KO mice as donors,there was minimum increase in BrdU uptake at 48 hours post transplantation.Conclusion IL-6 KO liver grafts fail to regenerate after liver transplantation.IL-6 is an important factor in liver regerative response.

Objective To explore the effect of kidney transplantation from donation after brain death (DBD) donors with terminal acute renal failure (ARF).Method The clinical data of kidney transplantation from DBD donors with ARF were retrospectively analyzed,and only standard criteria donors (SCD) were included.The results of kidney transplants from ARF donors were compared with those of kidney transplants from DBD donors with normal renal function (serum creatinine ＜ 133μmol/L) performed from January 2012 to March 2014.Result There were 13 donors with ARF and 27 donors with normal renal function (non-ARF donors).The ARF donors had significantly higher terminal serum creatinine than the non-ARF donors (394.9 ± 176.8 vs.75.4 ± 28.6 μmol/L,P＜0.001),but the initial serum creatinine (79.1 ± 17.2 vs.71.0 ± 22.8 μmol/L) and the best creatinine clearance rate (128.3 ± 33.0 vs.129.8 ± 46.8 ml/min) of two groups showed no significant difference (P＞0.05).Twenty-six recipients received kidney transplants from ARF donors (ARF group) and 54recipients received kidney trangplants from donors with normal renal function (non-ARF group).There was no significant difference in the incidence of delayed graft function and acute rejection between ARF and non-ARF kidneys (0 vs.1.9％,and 11.5％ vs.7.4％,respectively).The ARF group had significantly lower estimated glomerular filtration rate (eGFR) at 1st month after transplantation (54.3 ± 16.9 vs.62.5 ± 14.2 mL·min 11.73 m 2,p =0.025),but the eGFRs of two groups were similar at 6th and 12th month after transplantation.During a mean follow-up period of 11.5 months (range 3 to 28 months),actual patient and graft survival rate for both groups were 100％.Conclusion Kidneys from DBD donors with terminal ARF have excellent short-term outcomes and may represent another potential method to safely expand the donor pool.

Objective To evaluate the effect of endoscopic retrograde cholangiopancreatography (ERCP) in treatment of biliary complications after liver transplantation. Methods Data of 39 patients who underwent ERCP between January 2005 and December 2007 because of biliary complications after liver trans-plantation were retrospectively evaluated. Endoscopic sphincterotomy, dilatation, nasal-biliary drainage (ENBD) and stent placement were performed in 25 patients with biliary strictures (14 at anastomosis site and 11 at non-anastomosis site). ENBD and stent placement were applied in 6 patients with biliary leakage, while endoscopic sphincterotomy, ENBD and stone extraction with baskets were performed in 16 patients with biliary stones. Procedures were repeated when necessary. Results ERCP was successfully performed at a rate of 95.9% (94/98) without any severe complications. Strictures at anastomosis site were resolved in all patients (100%, 14/14), while for strictures at non-anastomosis site, only 27.3% (3/11) were cured. Biliary leakage was resolved in 83.3% (5/6) patients. Complete bile duet clearance was achieved in 81.3% (13/16) of the patients with biliary stones. Conclusion ERCP proves to be safe and effective in the treatment of post liver transplantation biliary complications with low incidence of severe complications.

BACKGROUND:Nowadays,liver grafts for transplantation are clinically sourced from non-heart-beating donors.Moreover,there is still no uniform determination of safe time limit points for non-heart-beating donor liver in warm ischemia and cold preservation.OBJECTIVE:To evaluate the application safety and curative effects of warm ischemia liver graft affected by varied cold ischemia time (CIT) in liver transplantation.DESIGN,TIME AND SETTING:A randomized controlled observation was performed in the Organ Transplantation Center,First Affiliated Hospital of Sun Yat-sen University between January 2006 and December 2007.PARTICIPANTS:154 cases who underwent non-heart-beating liver transplantation were included in this study.All liver graftsinvolved had a warm ischemia time(WIT) less than 10 minutes.METHODS:All cases were assigned into 3 groups according to CIT:group Ⅰ (CIT＜8 hours,n=58),group Ⅱ (CIT 8-12hours,n=62),and group Ⅲ (CIT 13-16 hours,n=34).The liver grafts were randomly allocated for the patients.Following liver transplantation,the same immunosuppression protocol was employed for each group.MAIN OUTCOME MEASURES:Following surgery,peak level of alanine aminotransferase (ALT),primary graft dysfunction (PGD) after liver transplantation,acute rejection response,biliary complications,vessel complications,perioperative infections,graft and recipient survival rate were compared among 3 groups.RESULTS:Follow-up time was 8-32 months.No PGD was detected in all 154 cases.Group Ⅱ showed postoperative ALT peak levels significantly higher than group Ⅰ (P＜ 0.05).There was no significant difference between groups Ⅰ and Ⅱin terms of acute cellular rejection,perioperative infection,biliary complication,vessel complication,graft survival rate,and recipient survival rate (P＞0.05).Compared with group Ⅰ,the group Ⅲ exhibited significantly increased postoperative ALT peak level,biliary complications,and perioperative infections,and significantly decreased graft and recipient survival rate (P＜0.05).CONCLUSION:Non-heat-beating-liver grafts with less than 10 minutes of warm ischemia can tolerance 12 hours of cold ischemia.More than 12 hours,postoperative liver transplantation complications ascend and,contradictorily,graft and recipient survival rate descend.

Objective To evaluate the diagnosis and treatment of early-stage hepatic artery thrombosis(HAT) after adult liver transplantation.Methods387 consecutive adult patients who underwent liver transplantation from June 2007 to October 2010 by the same surgery team in the Transplant Center,First Affiliated Hospital of Sun Yat-sen University were retrospectively studied.Hepatic arterial blood flow was monitored by color Doppler ultrasound (DUS) daily during the first week after transplantation.Ultrasonic contrast or hepatic artery angiography was performed on recipients with suspected HAT.Results10 patients developed HAT on 7(2-18)d after operation.The incidence of HAT was 2.6％ (10/387).Interventional therapy was performed in 2 patients with one patient who received a stent because of hepatic artery stricture.Three patients underwent emergent hepatic artery revascularization combined with intra-arterial urokinase thrombolysis treatment.One developed a rethrombosis and died.The remaining 2 patients received re-transplantation.Three patients died of liver failure and severe infection.The mortality rate was 40％ (10/387).ConclusionsIt is essential to diagnoses HAT by monitoring the artery flow by Doppler ultrasound screening in the early period after operation.Interventional therapy,emergent hepatic artery revascularization and re-transplantation are effective rescue treatments.Prevention of HAT is most important.
