Methods Six healthy men were subjected to the following experiments: ①pressurized anti G suit (KH X); ②pressure breathing for +Gz (PBG); ③pressurized anti G suit and PBG and AGSM (up to +9Gz for 10 s). Urine samples were collected before, immediately after, 30 minutes and 24 hour after the exposures for the determination of ? 1 microgolbulin (? 1 M). Results It was found that ①The G tolerances of subjects under 3 conditions were (6 25?0 52) G/10s, (8 17?0 26) G/10s, 6 5G/30s, and 9 00 G/10s, respectively. ②30 minutes after each series of exposure, the contents of ? 1 M in urine samples were increased ( P

Ultrasound can be used to visually evaluate brain structure, estimate intracranial pressure, and identify the function of cerebrovascular autoregulation and the reactivity of cerebrovascular carbon dioxide.It can also be used in the diagnosis of cerebral vasospasm and systemic circulation evaluation.Critical care ultrasound can help clinicians identify the primary injury of neurological system, prevent and effectively manage the secondary injury through bedside, real-time, non-invasive evaluation and monitoring.It can guide the implementation and evaluate the curative effect of brain protection algorithm.

ObjectiveTo investigate the expression and relevant function of protein kinase C (PKC)-α in kidney of rat with chronic arsenic poisoning.MethodsTotally 60 healthy SD rats of clean grade were randomly divided by body weight into 3 groups:high-dose arsenic exposure group (10.0 mg/kg),low-dose arsenic exposure group (0.4 mg/kg),and control group.The rats were exposed by drinking arsenic solution which was mixed with distilled water.Rats were weighed every 10 days and dose volume of arsenic solution was adjusted.After continuous exposure for 4 months,blood and urinary arsenic were determined.Rat kidneys were taken and stained by Immunohistochemistry SABC.PKC-o positive cells in the kidney were observed and counted,and its average gray value was analyzed with image analysis software (Biomias).ResultsProximal tubules PKC-α-positive cell count [(3.62 ± 1.90),(10.07 ± 3.22)/field],glomerular PKC-α-positive cell count [(3.62 ± 1.90),(10.07 ± 3.22)/field]in high and low arsenic group of SD rat kidney were lower than those of the control group [(60.00 ± 9.63),(18.57 ± 2.71/field,all P ＜ 0.05]; both urinary arsenic level[(7366.62 ± 1086.50),(1744.31 ± 300.12)μg,/L]and blood arsenic level [(31.59 ± 9.24),(16.58 ± 2.08)μg/L] in high-dose and low-dose groups were higher than those of the control group [(18.97 ± 3.58),(18.97 ± 3.58)μg/L,all P ＜ 0.05] ; the average gray values of SD rat kidney proximal tubule,glomerular PKC-o positive cells in high-dose and low-dose groups( 142.79 ± 11.16,122.15 ±5.91 ) were higher than that of the control group (114.33 ± 6.70,all P ＜ 0.05).ConclusionsArsenic can decrease SD rat kidney PKC-α -positive cells.The regulatory function of PKC-o in inhibiting cell apoptosis of kidney of rats with arsenic poisoning is weakened.

Objective To investigate insulin receptor (INSR) genotype exon 17 frequencies in women with polycystic ovary syndrome(PCOS) and to elucidate its role in the pathogenesis of PCOS. Methods The study involved 33 women with PCOS and 28 healthy control women who were genotyped for polymorphism of INSR gene exon 17 by single strand conformation polymorphism (SSCP) analysis. Body mass index (BMI), insulin sensitive index (ISI), the expression of INSR beta subunit, and serum concentration of luteinizing hormone(LH), total testosterone between the genotypes were compared. Results (1) The T -to- C mutation was observed in the INSR gene exon 17 (1008 bp). The frequency of the C/C genotype was significantly higher in patients (39%) than in the controls (11%) (P

BACKGROUND: Present existed procedure protocol for urinary fistula has some limitations, which can not reflect diseased region, pathological change, or severe condition of patients, OBJECTIVE: To establish the procedure protocol for urinary fistula diagnosis and treatment following renal transplantation, in addition, to investigate its significance in clinical practice. METHODS: A total of 102 cases with urinary fistula, including 67 male and 35 female, range in age from 21 to 57 years. According to the business management mode, we have designed the "five-step procedure protocol" for the diagnosis and treatment of urinary fistula after renal transplantation. Four diagnosis steps consisting of qualitative, located, quantitative and classified, as well as one treatment step. Among 102 cases of urinary fistula, 34 were adopted conservative treatment, including 24 cases with drainage tube and retention type catheter, 10 cases with indwelling ureteric stents at tubal bladder. Other 68 cases received surgical treatment. In 47 cases with simple fistula, 36 cases received ureter/bladder replantation, 11 cases with ureteral anastomosis. Twenty-one cases with complex fistula were treated with surgical prosthesis using omentum majus after repairing. RESULTS AND CONCLUSION: Among the 34 cases receiving conservative treatment, 2 got urinary tract infection repeatedly, and 5 got the stenosis of ureterovesical anastomotic stoma. Among the 68 cases receiving surgical treatment, 2 had ureteral stoma stricture, 1 ureterovesical anastomotic stoma stricture, and 1 ureteral countercurrent. In the surgical treatment series, 3 cases died from severe pulmonary infection elicited by urinary fistula. 77 cases were available for long-term follow-up, 22 were dropped out. In the 57 cases with simple fistula were followed up for 1-10 years, the transplanted renal function was normal in 40 cases, and 17 cases suffered from chronic rejection. 20 cases with complex fistula treated with surgical prosthesis using omentum majus were followed up for 1-7 years, 19 cases were normal, 1 patient had increased creatinine, which was returned to normal after intravenous glucocorticoid therapy. The design of "qualitative, located, quantitative and classified" standard for urinary fistula diagnosis following renal transplantation, and the establishment of "five-step procedure protocol", make urinary fistula diagnosis and treatment more ordered and standard, which is more feasible for selecting optimal therapeutic scheme.

Hydrocortisone-induced yang-deficiency animal model has now become the generally accepted model of yang deficiency. However, assessing the most appropriate dose of hydrocortisone is a long-term challenge. For analyzing the modeling dose, the authors have built several kinds of yang-deficiency models induced by hydrocortisone at different doses, and analyzed the experimental data with various mathematical statistical methods. In order to discuss the effects of the modeling dose on the basis of previous research, the authors introduced Ridit analysis.
