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.

The aim of the present study was to investigate the role of p38 MAPK in the renal tubular epithelial-mesenchymal transition (TEMT) induced by high glucose. In in vivo study, the rats were randomly divided into control (C), diabetes mellitus (DM) and insulin-treated DM groups. Immunohistochemical staining and Western blot were employed to determine the expression of p38 MAPK and p-p38 MAPK protein in renal cortex of rats. In in vitro study, primary renal tubular epithelial cells (PTECs) were cultured with normal glucose (5.5 mmol/L), high glucose (20 mmol/L D-glucose), high osmolality (20 mmol/L D-mannitol) and SB202190 (a p38 MAPK inhibitor) plus high glucose respectively for 72 h. The expressions of p38 MAPK, p-p38 MAPK, Snail1, transforming growth factor-beta1 (TGF-beta1), alpha-smooth muscle actin (alpha-SMA) and E-cadherin protein and mRNA were detected by immunocytochemical staining, Western blot and RT-PCR. The p38 MAPK and p-p38 MAPK were specifically upregulated by high glucose in both in vivo and in vitro studies. The p38 MAPK activation was abolished by insulin controlling hyperglycemia to normal level in DM rats and inhibited dramatically by SB202190 in high glucose-cultured PTECs. The protein and mRNA of alpha-SMA were markedly increased in PTECs cultured with high glucose and were 12-fold and 8-fold respectively over that in the normal glucose, which were significantly suppressed by SB202190. SB202190 down-regulated the high glucose-induced Snail1 protein expression in PETCs, and restored partly the depression of E-cadherin protein and mRNA. These results suggest that p38 MAPK mediates high glucose-induced TEMT via transcription factor Snail1.

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 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 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 evaluate the efficacy of intraoperative radiofrequency ablation and 125I therapy for preventing local recurrence in hepatocellular carcinoma (HCC) after hepatectomy.

METHODSSeventy-eight HCC patients with a tumor close to the first or the second hepatic portal underwent hepatectomy with a resection margin less than 1 cm from 1999 to 2001. All patients were randomly divided into control group and combined treatment group according to their check-in date (odd or even). In the control group, 38 patients were treated with hepatectomy alone, whereas in the combined group, 40 patients were treated with hepatectomy plus radiofrequency ablation and 125I implantation on surgical margin. All patients were followed up regularly.

RESULTSthe 1-, 3- and 5-year recurrent rate was 7.5%, 30.0% and 45.0% in the combined treatment group versus 18.4%, 60.5% and 86.8% in the control group, respectively, with a significant difference in the 3-year (chi2 = 7.340, P < 0.01) and 5-year recurrent rates (chi2 = 15.740, P < 0.01). The 1-, 3- and 5-year survival rate was 92.5%, 67.5% and 30.0% in the combined group versus 81.5%, 39.4% and 18.4%, respectively.

CONCLUSIONIntraoperative radiofrequency ablation and 125I therapy on the resection margin is effective to prevent local recurrence in HCC patients after hepatectomy, and to prolong their postoperative tumor free survival.

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.

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.
