To explore hemorrhage risk and the clinical significance of abnormal change of prothrombin time (PT), activated partial thromboplastin time (APTT), plasma fibrinogen (FIB), plasma thrombin time (TT) and d-dimer (D-D) in de novo acute leukemia (except for APL), the different bleeding manifestations of 114 cases of de novo acute leukemia with different coagulation indexes were analyzed retrospectively. The correlation between these blood coagulation indexes and the possible correlative clinical characteristics were analysed, including age, sex, type of acute leukemia, initial white blood cell(WBC) and platelet(Plt) count, the proportion of blast cells in bone marrow and cytogenetic abnormality of patients at diagnosis. The results indicated that the incidence of abnormal blood coagulation was as high as 78.1% for de novo AL patients. These patients with 5 normal blood coagulation indexes may have mild bleeding manifestation, but the more abnormal indexes, the more severe bleeding. Both PT and D-D were sensitive indexes for diagnosis of level II bleeding. Incidence of abnormal blood coagulation significantly correlates with the proportion of blast cells in bone marrow (χ(2) = 4.184, OR = 1.021, P < 0.05) and more with D-D (P < 0.01), while age, sex, type of AL, WBC count, Plt count and abnormality of cytogenetics did not correlate with abnormal blood coagulation. It is concluded that the coagulation and fibrinolysis are abnormal in most patients with de novo acute leukemia. More abnormal indexes indicate more severe bleeding, and both PT and D-D are sensitive indexes for diagnosis of level II bleeding. Higher proportion of blast cells in bone marrow predicts higher incidence of abnormal blood clotting. Acute leukemia with elderly age, high white blood cell count and adverse cytogenetics do not predict severer abnormal blood clotting. Detection of PT, APTT, TT, FIB, and D-D may help to judge whether the patients are in a state of hypercoagulability or disseminated intravenous coagulation, which will provide experiment evidences for early intervention and medication.

OBJECTIVETo evaluate the advantages and shortcomings of endoscopic thyroid surgery by trans-axilloareolar approach and trans-thoracoareolar approach.
METHODSEndoscopic thyroidectomy was performed in 238 cases from December 2003 to January 2006. The patients were randomly divided into two groups. One hundred and twenty-three patients received the trans-axilloareolar approach and 115 patients randomly received the trans-thoracoareolar approach procedure.
RESULTSAll the operations were succeed. The operating duration of trans-axilloareolar approach group and trans-thoracoareolar approach group were (69 +/- 29) min and (70 +/- 25) min (P > 0.05), the blood lost were (38 +/- ll) ml and (40 +/- 13) ml (P > 0.05), the average hospitalized days were (4 +/- 1.3) d and (4.5 +/- 1.2) d (P > 0.05), the rate of satisfaction with the cosmetic effects of the procedures were 97.5% and 85.2% (P <0. 05). There were no conversions to open surgery or any complications. The drainage was removed at 24 h to 36 h after the operation.
CONCLUSIONSEndoscopic thyroidectomy through trans-axilloareolar approach and trans-thoracoareolar approach is feasible, safe and cosmetic. The cosmetic effects of the trans-axilloareolar approach is better than the trans-thoracoareolar approach. The procedure selection depends on both the patient request and the technology of the surgeons.

The present study was aimed to explore the expressions of transforming growth factor-β1 (TGF-β1) and Snail1 in renal tissues of diabetic rats, and their role in tubular epithelial-mesenchymal transition (TEMT). Induced diabetic rats were randomly divided into 2-, 4-, 8-, 12-, 16-, 20-, 24-week and 16wA, 20wA, 24wA groups. The rats in 16wA, 20wA and 24wA groups were treated with insulin to control blood glucose to the normal level from the 13th week. The age-matched rats were set as controls. Blood glucose, 24-hour urine protein, serum creatinine (Scr), kidney index of rats were measured. PAS staining was used to observe the renal pathological changes. Immunohistochemical staining and (or) Western blot were employed to determine the expressions of TGF-β1, Snail1, E-cadherin, α-smooth muscle actin (α-SMA) and fibronectin (FN) proteins. The expressions of Snail1 and E-cadherin mRNAs in renal cortex were examined by RT-PCR. Blood glucose, 24-hour urine protein, Scr and kidney index increased remarkably in diabetic rats as compared with those in the control groups (P<0.05, P<0.01) and insulin-treated rats (P<0.01). TGF-β1 and Snail1 protein expressions could not be detected by immunohistochemical staining in the normal renal tissues, however, the strongly positive staining was observed in diabetic rat renal tubules. A time-dependent loss of TGF-β1 and Snail1 expressions was detected in the kidney of insulin-treated rats. In diabetic rats tubular α-SMA positive staining was seen at the 16th week. E-cadherin expression was lost in diabetic rats. The expressions of TGF-β1, Snail1 proteins and Snail1 mRNA were significantly up-regulated in diabetic rats, while down-regulated in insulin-treated rats (P<0.01). The expressions of E-cadherin protein and mRNA in the cortex were contrary to the expressions of TGF-β1 and Snail1. Therefore, TGF-β1 and Snail1 are possibly involved in the pathogenesis of TEMT in diabetic nephropathy rats.

OBJECTIVETo study the efficacy of laparoscopic placement of total peritoneum intraperitoneal onlay mesh (TPIPOM) for treatment of inguinal hernia.
METHODSTPIPOM was placed laparoscopically in 125 cases of inguinal hernia, and the clinical outcomes of the patients were observed and compared with 64 patients receiving transabdominal preperitoneal laparoscopic mesh repair (TAPP) and 53 with total extraperitoneal laparoscopic hernioplasty (TEP).
RESULTSThe laparoscopic operations were successfully performed in all the patients. In TPIPOM, TAPP and TEP groups, the operating time was 30.8-/+10.3 min, 68.4-/+22.4 min and 69.5-/+23.4 min (P<0.05), the mean hospital stay was 3.8-/+1.3 days, 4.3-/+1.5 days and 4.5-/+1.6 days (P<0.05), the average time to ambulation was 1.2-/+0.5 days, 1.8-/+0.7 days and 2.2-/+0.8 days (P<0.05), the duration of pain was 1.0-/+0.5 days, 1.6-/+0.9 days and 1.9-/+0.8 days (P<0.05), and the cost was 5000.8-/+800.5 yuan, 8000.5-/+950.6 yuan and 8900.2-/+750.3 yuan (P<0.05), respectively. No scrotum edema occurred in these patients. The patients were followed up for 59.9-/+6.5 months and recurrence was found.
CONCLUSIONTPIPOM is safe and effective for management of inguinal hernia with such advantages as minimal invasion, simple procedures, shorter operation time, reduced relapse and quick recovery.

OBJECTIVETo explore the follow-up visit, outcome and auxiliary diagnosis method on the cases with indeterminate antibody level measured by Western blotting as well as the related biological factors.
METHODSThe cases with indeterminate result were followed up according to the National Guideline for Detection of HIV/AIDS (2009) and samples were collected for HIV antibody detection, p24 antigen and nucleic acid were detected as a supplementary diagnosis at the same time. The samples were also be detected for HBV, HCV, TP, HTLV-I/II, ANA, and AFP, and the results were compared to that of screened positive and confirmed negative cases.
RESULTSA total of 73 were followed up successfully and taken a second HIV test, 25 cases were tested positive and 48 were tested negative for HIV during the follow-up period. For the 25 HIV positive cases, the HIV seroconversion rate was 100.00% at any time point when the interval between the first and returning detection was longer than 1 week. The major Western blotting bands for the cases with indeterminate result were p24 and gp160 and it was different between HIV positive and negative cases in Western blotting band profiles. The consistency and sensitivity of nucleic acid detection were higher than 90.00%, and were higher than that of p24 antigen (69.09% (38/55) and 27.27% (6/22)) (χ(2)(consistency) = 6.875, χ(2)(sensitivity) = 18.893, P < 0.05). The positive rates of ANA and AFP of indeterminate cases excluded from HIV infection were 20.83% (10/28) and 6.25% (3/48) and higher than that of screened positive and confirmed negative cases (0.00%), the difference had statistic significance (χ(2)(ANA) = 19.430, χ(2)(AFP) = 5.520, P < 0.05).
CONCLUSIONIt is critical to get timely diagnosis for the indeterminate cases according to the new national guideline for detection of HIV/AIDS. Nucleic acid detection has higher application value as auxiliary diagnosis for HIV infection than p24 antigen. The increased levels of ANA and AFP may be the factors resulting in the nonspecific indeterminate results.

OBJECTIVETo evaluate the therapeutic efficacy of simultaneous laparoscopic excision for the treatment of rectal carcinoma and synchronous hepatic metastasis.
METHODSTotally 38 patients with rectal carcinoma and synchronous hepatic metastasis detected by CT scan were included in this study. Among them, 23 patients in the group A were treated with laparoscopic surgery, and the other 18 patients in the group B with traditional abdominal operation to resect the rectal tumor and hepatic metastasis simultaneously. All patients received postoperative chemotherapy.
RESULTSAll the patients were treated successfully with no postoperative death in both groups. The mean operative time was 350 +/- 45 min in group A versus 342 +/- 38 min in group B (P > 0.05). The mean blood loss was 275 +/- 96 ml in group A versus 590 +/- 85 ml in group B (P < 0.01), and the average hospital stay was 12 +/- 1.5 days in group A versus 16 +/- 2.5 days in group B (P < 0.05). Only one patient in group A received blood transfusion of 200 ml during operation, while the average blood transfusion in group B was 500 +/- 100 ml (P < 0.01). The follow-up duration was from 36 to 72 months with an average duration of 45.3 months. The 1-, 3- and 5-year survival rates were 82.6%, 43.5% and 8.6% in the group A, versus 77.8%, 38.9% and 0% in group B, respectively (P > 0.05).
CONCLUSIONSimultaneous laparoscopic excision of rectal carcinoma and synchronous hepatic metastasis is safe, effective and minimally invasive with a similar survival achieved by traditional open abdominal operation.

OBJECTIVETo study the effect of laparoscopy combined with endoscopic and digital subtraction angiography in the treatment of severe acute pancreatitis (SAP).
METHODSNine-seven SAP patients were randomly divided into group A (n=32) with conventional treatment and group B (n=35) with combined treatment with laparoscopy, endoscopic and digital subtraction angiography in addition to the conventional treatment. The clinical indices and therapeutic effects in the 2 groups were compared.
RESULTSAfter treatment, the patients in group B had significantly lower APACHE score than those in group A (P<0.05), with also better hepatic, renal and lung functions (P<0.05). The serum TNF-alpha and IL-1beta levels was significantly lower, but IL-10 significantly higher in group B (P<0.05). The CT SPN was significantly lowered in group B as compared with that in group A (P<0.05). The patients in group B had significantly lower rate of organ failure (P<0.01) and higher successful rate in organ failure management (P<0.05), with also lowered inhospital mortality than those in group A (P<0.05).
CONCLUSIONLaparoscopy combined with endoscopic pancreaticobiliary duct drainage and digital subtraction angiography in addition to conventional treatment significantly improves the outcome and decreases the mortality of SAP patients.

BACKGROUNDRectal carcinoma patients are often accompanied by hepatic metastasis. The aim of this study was to evaluate the therapeutic efficacy of simultaneous laparoscopic excision for rectal carcinoma with synchronous hepatic metastasis.
METHODSA total of 41 patients with rectal carcinoma and synchronous hepatic metastasis detected by CT scan were included in this study. Among them, 23 patients underwent laparoscopic surgery and 18 patients underwent traditional open surgery to simultaneously remove the rectal tumor and hepatic metastasis lesions. All patients received postoperative adjuvant chemotherapy. All the patients were followed up from 36 to 72 months (mean 45.3 months).
RESULTSAll the operations were performed successfully and no patient was turned to open surgery in laparoscopic group. The mean blood loss, the mean postoperative hospital stay, the mean blood transfusion and the mean intestinal functional recovery time showed a significant difference between the two groups (P < 0.05). The 1-, 3- and 5-year survival rates were 82.6%, 43.5% and 8.6% in the laparoscopic group, without significant difference compared with the open group (77.8%, 38.9% and 0) (P > 0.05).
CONCLUSIONSSimultaneous laparoscopic excision for rectal carcinoma and synchronous hepatic metastasis is safe and effective with similar survival achieved by the traditional open abdominal surgery.
