Objective To investigate the expression of TGF-β and TGF-β receptor in human breast cancer cell Bcap-37 inhibited by soybean isoflavones. Methods mRNA and protein of TGF-β1、TGF-βRⅠ in Bcap-37 cells were examined with reverse transcription ploymerase chain reaction(RT-PCR) and immunohistochemistry after cells were treated with daidein or genistein for 1-4 d.The expression of TGF-β1 and TGF-β2 was determined with TGF-β resistance test. Results The TGF-β1, TGF-β2 and TGF-β recepor increased in Bcap-37 cells at a concentration of 3×10-5 mol/L of genistein. No changes was found when treated with daidzein. Conclusion Genistein may inhibit the proliferation of Bcap-37 cells and accompany with increasing expression of TGF-β1, TGF-β2 and TGF-β receptor.

OBJECTIVETo study the method and effects of multi-stage manipulative reduction and homemade splint fixation in the treatment of tibia shaft fractures.
METHODSTwenty-two patients (16 male and 6 female) were involved the retrospective study. The average age was 33 years (from 6 to 54 years). Single tibia shaft fracture was in 15 cases and tibiofibular fracture in 7 cases. Fracture site: 3 cases were in the upper part of the tibia, 4 in the middle part and 15 in the lower part. Fracture pattern: oblique fracture was in 8 cases, spiral fracture in 5 cases, comminuted fracture in 4 cases and transverse fracture in 5 cases. All the patients were treated with multi-stage manipulative reduction and homemade splint fixation.
RESULTSAll the patients were followed up from 3 to 15 months (mean 6 on months). There were malunion of fracture in 1 case, delayed union in 1 case and nonunion in 1 case. The results were excellent in 18 cases, good in 3 cases and poor in 1 case according to WANG Xu-dong assessment criteria.
CONCLUSIONOn the base of traditional manipulative reduction and splint fixation, multi-stage manual correction could stabilize the broken part and prevent displacement. It had the characteristics of easy operation, reliable fixation, rapid union of fracture, few complications and influences on joint function. Multi-stage manipulative reduction and homemade splint fixation is one of the most reliable methods for closed tibia fracture.

BACKGROUNDThe effects of triterpenic acid from Prunella vulgaris L. (TAP) on diabetes and its mechanism are uncertain. The aim of this study was to investigate the effects of TAP on antihyperglycemic, antioxidant, and pancreas-protective in streptozotozin (STZ)-diabetic rats.
METHODSThe diabetic model was produced by injection of 60 mg/kg STZ. Blood was drawn from the tail vein of rats after 72 hours. Rats with blood glucose ≥ 16.7 mmol/L were considered diabetic. Diabetic rats were randomly divided into four groups: (1) Diabetes rat (STZ), (2) Diabetic rats treated with 50 mg/kg of triterpenic acid from Prunella vulgaris L (STZ + TAP50), (3) Diabetic rats treated with 100 mg/kg TAP (STZ + TAP100), and (4) Diabetic rats treated with 200 mg/kg TAP (STZ + TAP200). Normal rats (n = 10) acted as the control group (NC). TAP was administered by the intragastric route once each day for six weeks. Body weight and the concentration of blood glucose (BG) were measured after three and six weeks. Fructosamine (FMN), malondialdehyde (MDA), and nitric oxide (NO), and the activities of nitric oxide synthase (NOS) and superoxide dismutase (SOD) in serum were determined after six weeks using commercially available kits following the manufacturer's instructions. Pathologic changes in pancreatic β-cells were also investigated by microscopic examination after hematoxylin-eosin (HE) staining. The level of SOD mRNA in pancreatic β-cells was measured by polymerase chain reaction (PCR).
RESULTSThe levels of BG, FMN, NO, and MDA and the activities of NOS in serum in the four diabetes groups were significantly increased compared with the control group (P < 0.01). The activity of SOD in serum and the body weight was significantly decreased compared with the control group (P < 0.01). After administration of TAP to diabetic rats for six weeks, the body weight and the levels of BG, FMN, MDA, NO and the activity of NOS in serum decreased significantly compared with the STZ group in a dose-dependent manner. The activity of SOD in serum and body weight increased significantly compared with the STZ group in a dose-dependent manner. In addition, diabetic rats showed a significant decrease in SOD mRNA expression in pancreatic β cells. However, these changes were reversed by TAP. Histopathological examination also showed the protective effect of TAP on pancreatic β cells.
CONCLUSIONSTriterpenic acid from Prunella vulgaris L. has an anti-diabetic effect, by controlling blood glucose and antioxidants, and has a protective effect on the pancreas.

BACKGROUNDThe surgical management of the absence of the vagina is a complex problem and constitutes a significant technical challenge. As the laparoscopy has been an important tool for the treatment of uterovaginal anomalies, we evaluated the feasibility of laparoscopic vaginoplasty using an ileal segment retrospectively.
METHODSTotally 86 patients who underwent laparoscopic vaginoplasty using an ileal segment in Beijing Anzhen Hospital during February 2004 to July 2007 were enrolled in this study. Of the 86 patients, 70 (81.4%) underwent primary operations and 16 (18.6%) secondary operations. Nineteen (22.1%) patients underwent total laparoscopic vaginoplasty and 67 (77.9%) patients underwent laparoscope-assisted vaginoplasty. The operation time, cost of hospitalization, and hospital duration were compared between the two laparoscopic groups. The Student's t test and the Mann-Whitney test were used to examine the differences.
RESULTSAll the surgeries were successfully completed with no any intraoperative complication. There were three major surgical complications in the postoperative period: one case of intra-abdominal hemorrhage, one case of meatal stenosis, and one case of intestinal obstruction. The mean follow-up period of this series was 18 months. Seventy-eight patients were satisfied with their sexual lives after the surgeries except 5 women complaining of vaginal stenosis and 3 with no sexual partner during the follow-up. Significant differences were obtained between total laparoscopic and laparoscope-assisted vaginoplasty groups, such as the operation time, cost of hospitalization, and hospital duration (P < 0.01). There were no significant differences in sexual function between the two groups.
CONCLUSIONSThe laparoscopic vaginoplasty using an ileal segment is satisfactory for cosmetic, functional, and anatomic results. Vaginoplasty with an ileal segment, performed by either total laparoscopic or laparoscope-assisted techniques, has a high success rate for a functional vagina.

OBJECTIVETo analyze the clinical characteristics of living-related kidney transplantation (LRKT).
METHODSFrom January, 2004 to December, 2008, 175 LRKT were performed including 63 cases (36%) of parent-child relations and 49 cases (28%) of sibling relations between the recipients and donors. Out of 175 donors, 52 were 50 years old or above, 4 had microscopic hematuria (including 2 with also hypertension), 2 had kidney stone, and 2 had high body mass index (BMI). Zero-point graft biopsy was performed in 59 donors, and abnormalities were found in 15 of them. The recipients were at the age of 33-/+10.5 years, and the primary diseases are mainly dominant glomerular nephritis (72.6%, 127/175), and with a few cases of diabetes (4%, 7/175) and hypertensive nephropathy (4%, 7/175).
RESULTSSerum creatinine of the donors was 102-/+22.5 micromol/L at 7 days postoperatively, and 92-/+19.1 micromol/L at one month. One recipient died of severe pulmonary infection. Two recipients underwent graft nephrectomy due to anastomotic stenosis with concomitant acute graft rejection and renal arterial embolism. The one-year survival rates of the patients and grafts were 99.3% and 98.2%, respectively. The incident rates of accelerated rejection and acute rejection were 1.1% and 14.9%, respectively. Other complications included impaired liver function (22.3%), infection (9.7%) and leucopenia (4.6%). The renal arterial stenosis occurred in 2.3% (4/175) of the recipients.
CONCLUSIONSThe recipients of living-related and cadaveric kidney transplant have different primary kidney disease spectrums. Differential diagnosis and treatment of acute rejection and renal artery or anastomotic stenosis can be of vital importance. Marginal donor kidneys with appropriate inclusion criteria can be safely used for transplantation. With good short-term patient and graft survival, LRKT needs further study to evaluate its long-term effect.

OBJECTIVETo study the anatomy characters of renal artery and the treatment of multiple arteries in living donor renal grafts.
METHODSRecords of 142 living donors were analyzed in our center. We analyzed the anatomic structure of renal arteries by DSA and CTA pre-transplantation. Thirty-one kidneys with multiple arteries were transplanted after reconstruction. Then clinical effects were compared between multiple-renal-arteries group (n=31) and single-renal-artery group (n=111).
RESULTSThe incidence of multiple renal artery was 30.99%, and there was no difference between both sides (left kidney 22.54%, right kidney 22.13%). If the multiple artery occurred in left or right kidney, the incidence of the multiple artery occurred in the other side was 56.25% and 60.00%, respectively. The diameter of left main renal artery was more magnanimous (P=0.001) and the first branch was more closed to abdominal aorta (P=0.004). Operation time and warm/cool ischemia time were longer in the multiple-renal-arteries group. However, estimated blood loss, delayed graft function, acute rejection and flow rate of arcuate artery were similar in both groups, the same as serum creatinine and serum creatinine clearance rate on day 7, 1 month and 3 month post-operation. It was shown by repeated measures ANOVA that graft with multiple arteries didn't affect the tendency of renal function at early time post-operation.
CONCLUSIONComprehending the character of renal artery and accurate treatment of multiple artery anastomosis are critical for the effect of the living kidney transplantation.

OBJECTIVETo investigate the effects of dopamine and norepinephrine on the renal function in the patients with septic shock.
METHODSEighty-seven patients with septic shock were divided into three groups (group A, B, C) according to the biggest infusing rate of norepinephrine, with the infusing rate of 0.5 - 0.9, 1.0 - 1.5, 1.6 - 2.0 microg x kg(-1) x min(-1), respectively. Mean arterial blood pressure (MAP), heart rate (HR), urine output, blood urea nitrogen (BUN), creatinine (CRE), urine albumin (U-ALB) and urine beta(2)-microglobulin (Ubeta(2)-MG) as well as APACHE III score in all the patients were detected.
RESULTSBefore anti-shock therapy was given, hypotension, tachycardia and oliguria occurred in all the 87 patients, and CRE, BUN, U-ALB, Ubeta(2)-MG and APACHE III score were abnormal in most cases. With the anti-shock therapy, MAP, HR, urine output and BUN, CRE in all patients returned to normal levels gradually, and U-ALB, Ubeta(2)-MG levels and APACHE III score also restored but still remained abnormal.
CONCLUSIONSThe first aim of treating septic shock should be restoring the organ blood supply, and based on volume resuscitation, dopamine, noradrenaline and other vasoactive drugs could be combined to maintain circulatory stability.
