Objective To access evaluate the efficacy and safety of on-line hemodiafiltration for treating a-cute cerebrovascular disease (ACVD) patients complicated with hyperosmolar nonketotie diabetic coma (HNDC).Method Totally 11 patients of ACVD complicated with HNDC were observed for this prospective control study.All of them underwent on-line hemodiafiltrafion for 90 minutes using Fressnius 4008S Hemodialysis Machine withONLILNEplus TM and F60 one hour after final diagnosis was made. The bicarbonate ultrafiltrate rate was set at 500ml/min and blood flow at 150 ～ 180 ml/min; and the substitute fluid were infused with post-dilution at 50 ～ 60ml/min. The symptom of brain edema and cardiac insufficiency during the same course of treatment was observed.Blood were taken from the patients to detect serum kalium, serum glucose, serum natrium, BUN and plasma os-motic pressure at one hour before treatment and six hours after treatment, respectively. The change of in conscious-ness and adverse effects were evaluated at 24 hours after treatment. Results All patients were treated successful-ly. The blood glucose, serum natrium, serum kalium, BUN and plasma osmotic pressure were decreased after on-line hemodiafiltration. Among the 11 patients, consciousness was improved obviously in 8 patients, 3 patientsdied, accounting for 73% of successful effectiveness. Conclusions The on-line hemodiafiltration was effectiveand safe for treating ACVD patients complicated with HNDC.

Objective To study the relationship between P16,CyclinD1 and P53 anti-oncogene and the gen- esis of hydatidiform mole.Methods 30 samples of hydatidiform moles and normal early pregnant aborted placenta villi respectively were obtained to detect the P16,CyclinD1 and P53 anti-oncogene expression in two kinds of tissues by using SP immunohistochemical staining.Results Compared with that of normal villi,the expressions of P16,P53 and CyclinD1 anti-oncogene were quite different in hydatidiform moles.The expression of P16 was all positive,while CyclinD1 and P53 were all negative in the chorion of early gestation.A descending tendency of P16 expression was found,while the expression of CyclinD1 showed an ascending tendency.The positive rate of P16,CyclinD1 and P53 expression was significantly different between the groups.It was also observed that there was significant difference between the P16 and the proliferation trophocyte.Conclusion P16,CyclinD1 and P53 anti-oncogene have a close relationship with the genesis of human hydatidiform mole.

Objective To evaluate the safety of surgical procedures for patients after heart valve prosthesis implantation.Methods Clinical data of 12 cases with heart valve prosthesis implantation undergone other surgical treatment from November 1996 to December 2005 were retrospectively analyzed.All the cases had routine oral warfarin with prothrombin time (PT) of 20.0—28.3 s averaged 23.5 s, international normalized ratio (INR) for prothrombin of 1.79—2.23 averaged 1.95 and heart functional class Ⅰ—Ⅲ.Among them,appendectomy was performed in three cases with acute appendicitis,reposition and repair in one with inguinal hernia,radical gastrectomy in two with gastric carcinoma,left hemicolectomy in one,cholecystectomy in three,left femoral head replacement in one,and bilateral high ligation and ablation of great saphenous vein in one.Elective surgical operation was performed in seven cases,and emergency operation in five.In those with elective surgery,warfarin was stopped 2—3 days before operation,while 5—10 mg vitamin K_1 was injected intramuscularly 6—8 hours before emergency surgery with preoperative median PT of 15.1 and 15.3 s and median INR of 1.24 and 1.30,respectively.In operation,5—10 mg vitamin K_1 were injected intravenously into the patients by drip depending on their bleeding on the surface of wound.ECG,blood pressure,hemoglobin and oxygen saturation were routinely monitored for all the cases intraoperatively and postoperatively.For the cases with heart function above class Ⅱ,fluid infusion was adjusted based on intubated central venous pressure,and for those with general anesthesia,analyses of blood gases and electrolyte were monitored routinely in operation.Results OPeration time averaged 20—160 rain in all the 12 patients,with blood loss 5—280 ml in average and without complications of massive hemorrhage,thrombosis and heart failure.Conclusions Surgical operation was safe for patients with heart valve prosthesis implantation,if preoperative PT and INR were adjusted to about 15 s and 1.30,respectively by cessation of warfarin or application of vitamin K_1,combined with careful manipulation and strengthened perioperative management.

Objective To explore the clinical application of percutaneous endoscopic gastrostomy in gastroin- testinal nutrition among critically ill patients.Methods Twenty-two patients were undertaken percutaneous endo- scopic gastrostomy under the lead of gastroscope.The puncturatio site was located in anterior wall of stomach.Results All the procedures were performed successfully for one time.Intraoperational blood pressure was very steady.At the same time,intraoperational SpO_2 of the patients all exceeced 97%.The bleeding amount and operation time were respectively (3.8?1.9) ml and (15.5?2.3) min.Severe complications such as gastrostoma,gastrocolic fistula, pneumoperitoneum,refluxing or aspiration of gastric juice,inhalant pneumonia didn't occur after the operation.Con- clusion Percutaneous endoscopic gastrostomy was safe and feasible among critically ill patients who needed gastroin- testinal nutrition because of its slight injury,little bleeding and shorter operational time.

OBJECTIVESTo study the effect of nitric oxide (NO) and total antioxide capacity (T-AOC) on the germ cell apoptosis in the cryptorchidism rat.

METHODSImmature rats (22 day-olds Sprague Dawley) were selected to make the model of unilateral cryptorchid. Germ cell apoptosis was examined by terminal-deoxynucleotidyl transferase mediated d-UTP nick end labeling (TUNEL). Biochemical parameters (NO, T-AOC) were evaluated with spectrophotometric determination.

RESULTSAt the seventh day after the operation, as compared to the normal side testis, the number of apoptotic germ cells increased significantly in the undescended testis (P < 0.01), but the testes weight decreased predominantly; the NO level in the undescended testis was significantly higher than that in the normal side testis, and the T-AOC level was predominantly lower (P < 0.01).

CONCLUSIONSExperimentally-induced cryptorchidism can lead to the increase of grem cell apoptosis in rat. The results is closely related to the increase of No level and the decrease of T-AOC.

OBJECTIVESTo investigate the mechanism of genitofemoral nerve in the contralateral testes damage of unilateral cryptorchid rats.

METHODSAfter unilateral cryptorchid rat model (21-day) was made and the ipsilateral genitofemoral nerve was divided, the germ cells apoptosis and the concentrations of lactate of contralateral testes were detected and compared after 120 days.

RESULTSAfter the ipsilateral genitofemoral nerve was divided, the germ cells apoptosis and the lactate levels of the contralateral testes were all decreased from (17.28 +/- 1.36)% to (5.76 +/- 0.76)% and (2.19 +/- 0.24) mmol/L to (1.70 +/- 0.31) mmol/L, respectively.

CONCLUSIONSThe damage pathway of the contralateral testes of unilateral cryptorchidism probably related to the apoptosis of the germ cells which caused by the reflex decrease of the contralateral testicular blood flow via the transmissions of genitofemoral nerve.

The aim of this study was to determine the seroprevalence and risk factors of fascioliasis in yaks, Bos grunniens, from 3 counties of Gansu Province in China. A total of 1,584 serum samples, including 974 samples from white yaks from Tianzhu, 464 from black yaks from Maqu, and 146 from black yaks from Luqu County, were collected and analyzed using ELISA to detect IgG antibodies against Fasciola hepatica. The overall F. hepatica seroprevalence was 28.7% (454/1,584), with 29.2% in white yaks (284/974) and 27.9% in black yaks (170/610). The seroprevalence of F. hepatica in yaks from Tianzhu, Luqu, and Maqu was 29.2%, 22.6%, and 29.5%, respectively. Female yaks (30.9%) had higher F. hepatica seroprevalence than male yaks (23.4%). Also, F. hepatica seroprevalence varied by different age group from 24.1% to 33.8%. Further, the seroprevalence ranged from 21.8% to 39.1% over different seasons. Interestingly, the season and age of yaks were associated with F. hepatica infection in yaks in the investigated areas. These findings provided a basis for further studies on this disease in yaks from 3 counties of Gansu Province in northwestern China, which may ultimately support the development of effective control strategies of fascioliasis in these areas.
