Objective To investigate arterial blood gas(ABG)changes induced by different intra- abdominal pressures during CO_2 pneumoperitoneum in rabbits with lung and liver impact injury under controlled hemorrhage.Methods In this study 75 rabbits were randomized into nine groups(6 rabbits in each group)according to the amount of blood loss(6 ml/kg、12 ml/kg、22 ml/kg)and intra-abdominal pressures(5 mm Hg,10 mm Hg,15 mm Hg).After model was established successsfully,respiratory rates (RR),ABG and death rates were observed at pre-pneumoperitoneum,after 0.5 hour and 2 hours under pneumoperitoneum and 0.5 hour after desufflation.Results Without pneumoperitoneum,different blood loss exerted different effect on arterial blood gas:RR,PaCO_2 increased(P

Objective To investigate the kinetic expression level of chemokines (MCP-1 and MIP-2) in vagina of a murine model of vulvovaginal candidiasis (VVC).Methods The estrogen-treated murine model of VVC was set up.Vaginal specimens were obtained in different duration after inoculation of C.albicans intravaginally.Semi-quantitative RT-PCR was applied to determine MCP-1 and MIP-2 mRNA levels in these tissues.Results Compared with the control mice treated with olive oil,persistent growth of C.albicans was found from the 2nd day to 21st day after inoculation in estrogen-treated mice.Significantly higher levels of MCP-1 mRNA were observed in vaginal tissues in infected estrogen-treated mice than those in other 2 groups,infected but non estrogen-treated mice and estrogen-treated but uninfected mice.The high level of MCP-1 mRNA maintained from the 4th day to 21st day in infected estrogen-treated mice.It was also found that levels of MIP-2 mRNA were significantly higher in the vagina in the 2nd day in 3 groups of mice than those in naive mice,however,no significant difference was shown among 3 groups throughout the study period.Conclusion High level of MCP-1,rather than MIP-2,may be associated with susceptibility to VVC.

Objective To study the effect of phonophoresis on transdermal delivery of sinomenine hydrochloride ( SH ) gel in vitro. Methods Ultrasound at one of two frequencies ( 800 kHz or 1 MHz) was applied with a sonicator with a transducer in this study. The skin of male Sprague-Dawley rats was used as the model and SH gel was used as the ultrasound couplant. The permeation rate of SH was detected using a modified Franz diffusion cell maintained at 32±0.5℃ and filled with 20% polyethylene glycol 400 physiological saline solution. The transdermal phonophoresis experiments were carried out in five groups: Group Ta, f=800 kHz, / = 0.75 W/cm2, t = 10 min:Group Tb,f=1 MHz,I=0.7 W/cm2, t=10 min; Group Tc,f=1 MHz,I=0.35 W/cm2, t=10 min; Group Td,f=800 kHz, I = 1.5 W/cm2, t = 10 min and Group Tc,f=800 kHz, I=1.5 W/cm2,t=5 min. There was also a control group (C) in which the SH was allowed to diffused passively. Samples were withdrawn at the indicated intervals and the concentration of SH was determined by high-performance liquid chromatography. The transdermal parameters such as average accumulated delivery quantity per unit area Q8h, average transdermal steady delivery rate J, and Tlag were calculated. Results The Q8h and Js of the control group were 20.65±10.23 μ/cm2 and 3.02±0.11μ/cm2/h respectively. The phonophoresis parameters in groups Ta and Tb were, on average, significantly higher than in the control group. The parameters in group Tb were significantly larger, on average, than in Te. In group Td the parameters were significantly larger than in groups Ta and Te. Conclusions The results show that phonophoresis can enhance the transdermal delivery of SH. Phonophoresis variables such as frequency and time influence its effects on drug permeation. Almost no change was observed in the structure of the skin after phonophoresis, though under a scanning electron microscope the surface of the corneum appeared rough and porous. Phonophoresis is there-fore an effective and safe method for SH transdermal delivery, and the effect is positively relation with the applied intensity and exposure time.

OI To research the new interhemispheric approach treatments of removing different large or huge sellar region tumor. Methods To remove 36 cases of different infiltrated-growth large or huge sellar region tumors by interhemisphefic approach microsurgery. Results In the 36 cases, total removal was achieved in 29, subtotal in 5 and most-partly in 2, and without any severe complications or death occured. 12 in 18 functional pituitary adcnoma were followed up, 10 cases got recovery on hormone level, and the level in 2 cases reduced ob ously. 2 cases recurred, both received γ-knife treatment. Conclusion The new interhemispheric approach surgery is important for large or huge invasive sellar region tumor.

ObjectiveTo explore the clinical and pathological characteristics in diagnosing the renal diseases with diffuse glomerular nodular changes. MethodsThe clinical and pathological data of 127 patients whose renal pathological feature was mainly diffuse glomerular nodular changes were retrospectively analyzed. ResultsThe most common diagnosis was diabetic nephropathy and renal amyloidosis, and sometimes light chain deposit diseases and Mix cryoglobulinemia. ConclusionDiffuse glomerular nodular changes occurred in many diseases. We should make differential diagnosis based on the clinical symptoms, the results of laboratory examinations and the renal pathological characteristics.

Objective To investigate the mRNA expression of survivin, livin and XIAP gene in peripheral blood of patients with gastric cancer and its relationship with clinico-pathological features.Methods This study included 50 patients with gastric cancer and 20 healthy donors. The expression of survivin, livin and XIAP gene was detected by reverse transcription-quantitative polymerase chain reaction (RT-QPCR) using a molecular beacon probe, while recombination plasmid containing the sequence of survivin, livin and XIAP was standard. The relationship between copies of survivin, livin and XIAP gene expression in peripheral blood with gastric cancer and clinical data was analyzed. Results A linear standard curve was obtained between 103 ～ 1010 copies. The copies of survivin, livin and XIAP mRNA in peripheral blood of patients with gastric cancer did not correlate with gender, age, and histological types ( P ＞ 0.05). There were positive relationships between copies of survivin, livin and XIAP gene with lymph node metastasis and TNM stage (P ＜0.05 ). The expression of survivine, livin and XIAP was all negative in peripheral blood of healthy people. 52% (17/33) of patients suffered from recurrence or metastasis who had positive expression of survivin and/or livin and/or XIAP mRNA, while it was 18% (3/17)among the negative survivin and/or livin and/or XIAP mRNA caces ( P ＜ 0.05). Conclusions The expression of survivin, livin and XIAP mRNA can be used to detecte micro-metastasis in peripheral blood circulation of gastric cancer.

Objective To explore the age-and sex-specific body composition of normal children in Beijing area.Metheds The subjects were a total of 587 children of 6-14 years old,who were recruited from Beijing schools.All of them had relative weight within normal range(80%～120%),and no chronic disease.The relative weight was obtained,according to standard weight,using the follo-(wing) formula: relative weight(%)=(body weight/standard weight) ?100.Body compositions were estimated with a bioelectrical impedance analyser,which had been proved to be reliable and valid for determining the percentage of body fat.Results Not only fat free mass(FFM) but also fat mass(FM) increased monotonically with age in both sexes.FFM was higher in boys than that in girls at all ages.FM was significantly higher in girls than that in boys aged 6 to 8 years old;however,there was no significant difference for FM between sexes aged 9-14 years old.Patterns of change in mean ratio of body fat(%BF),with age differed by sex.Percent age of BF was significantly higher in girls than that in boys at all ages except at 10 and 11 years old. In boys,%BF increased with age,while in girls it remained nearly constant from age 6 to 10 years old,and gradually increased from age 10 to 14 years old.Body mass index(BMI) increased steadily with age in both sexes,and boys had consistently higher BMI than girls.In boys,the increase in BMI was steeper from age 10 to 14 years old.Even in the subjects with BMI
