Objective To investigate the serum cystatin C (CysC) level and explore its relationship with cytokines and atherosclerosis (AS) in maintenance hemodialysis (MHD) patients.Methods A total of 110 stable MHD patients undergoing hemodialysis for at least six months and 60 healthy control people were enrolled in the study.Serum levels of CysC and high-sensitivity Creactive protein (hsCRP) were measured by immunoturbidimetry.The serum levels of total homocysteine (tHcy),IL-1β,IL-6 and TNF-α were determined by ELISA.Prevalence of atherosclerosis was detected by carotid ultrasonography.The relationship of CysC level and cardiac geometry incidence in MHD patients was analyzed by Logistic regression model.Results The serum CysC level was significantly higher in MHD patients as compared with healthy controls [(6.19±0.95) mg/L vs (0.76±0.21) mg/L,P＜0.01],and the serum levels of hsCRP,tHcy,IL-1β,IL-6,TNF-α were significantly higher in MHD patients than those in healthy control group (P＜0.05 or P＜0.01).The serum CysC level was higher in MHD patients with carotid artery atherosclerosis compared to patients without carotid artery atherosclerosis (P＜0.05).CysC was positively correlated with hsCRP,tHcy,IL-1β,IL-6,TNF-α respectively (P＜0.05 or P＜O.01),and was positively correlated with carotid intimal medial thickness (IMT) and AS.Besides,a negative correlation was found between the serum CysC level and the serum albumin level (P＜0.05),while CysC was positively correlated with dialysis duration,systolic pressure and iPTH (P ＜0.05).Conclusion Serum CysC level is significantly higher in MHD patients and is correlated with hsCRP,tHcy,IL-1β,IL-6,TNF-α as well as carotid artery atherosclerosis,which indicates that CysC is an independent risk factor of AS in MHD patients.

OBJECTIVE:To investigate the effects of sevoflurane combined with remifentanil on intraoperative related indica-tors and quality of postoperative recovery in patients with general anesthesia. METHODS:52 patients with elective abdominal sur-gery were randomly divided into observation group and control group. All patients were treated with etomidate 0.3 mg/kg+atracuri-um 0.5 mg/kg+remifentanil 1μg/kg for anesthesia induction;then observation group was received sevoflurane by inhalation and con-trol group was propofol by infusion. The SBP,DBP,HR and BIS in 2 groups were recorded before anesthesia induction(T0),after anesthesia induction(T1),time of intubation(T2),skin incision(T3),10 minutes after establishing pneumoperitoneum(T4),end of pneumoperitoneum(T5) and extubation(T6),respectively. Operation and anesthesia duration,recovery time and extubation time, MMSE score and incidence of adverse reactions were recorded. RESULTS:SBP and HR in T6 and DBP in T4-6 in 2 groups were sig-nificantly higher than T0 of same group,BIS in T1-5 was significantly lower than T0,the differences were statistically significant(P<0.05),however,there was no significant difference between 2 groups (P>0.05). Recovery time and extubation time in observa-tion group were significantly lower than control group(P<0.05),there was no significant difference in the operation and anesthesia duration between 2 groups(P>0.05). MMSE scores in 2 groups were significantly lower than before after 0.5 h and 1 h of extuba-tion,and control group was lower than observation group(P<0.05 or P<0.01);MMSE scores in 2 groups were significantly high-er than 0.5 h and 1 h after extubation(P<0.05),however,there was no significant difference between 2 groups and before(P>0.05). There was no significant difference in the incidence of adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Sevoflurane combined with remifentanil has satisfactory anesthesia,sevoflurane has better controllability,with good safety.

Objective To investigate the new method of ureter bladder anastomosis in renal transplantation.Methods The ureter was pulled into bladder for 1.2 cm through tunnel at the lateral- top of bladder wall,and the ureter fixed on the bladder wall by 2-3 acus with catgut suture.Results Forty of 42 patients had no complications,and recovered very well,except for 1 cases of necrosis caused by acute rejection and 1 case on urine leakage caused by catheter obstruction from blood clot.Conclu- sion This method is simple,easy to operate,safe and reliable with less complications.

Objective To study the supporting role of traditional Chinese medicine GanFuAn in the treatment of high-risk state of liver cancer by color Doppler ultrasound.Methods Based on a number of joint detection of tumor markers,85 patients of liver cancer were selected from patients with chronic hepatitis B.Among these 85patients,50 patients were selected in a treatment group and treated with Chinese herbal preparation GanFuAn,with ultrasound and tumor markers serving as joint monitoring; while the other 35 patients were selected in a control group and treated with conventional treatment.Results In the treatment group,the liver tumor markers or liver tumor continually diminished.5 cases showed tumor disappear.38 cases showed effective results,while 7 cases showed no effects.The total incidence rate of liver cancer was 14％;while in the control group,none case showed tumor disappear.20 cases showed effects and 15 cases showed none effects.The cumulative incidence rate of liver cancer induced by chronic hepatitis was 43％,with all the cases have been confirmed by pathology.Conclusion Color doppler ultrasound was an intuitive,non-invasive dynamic method to monitor liver tumor's growth and decline.

To study the effect of sodium aescinate in inducing human breast cancer MCF-7 cells apoptosis and its possible mechanism. MTT assay was used to detect the inhibitory effect of sodium aescinate on the proliferation of MCF-7 cells. The morphological changes were observed under inverted microscope. DAPI nuclear staining was used to detect the changes in cell nucleus. Annexin V-FITC/PI flow cytometry was adopted to test the apoptosis rate. Changes in apoptosis-related proteins (PARP, cleaved caspase-8 and pro-caspase-3), cell survival-associated signal molecules (AKT and ERK) and their common upstream kinase SRC was detected by Western blotting. The result showed that after different concentrations of sodium aescinate were used to treat breast cancer MCF-7 cells, they inhibited the proliferation of MCF-7 cells in a dose-dependent manner, induced cell apoptosis (typical morphological changes in nucleus, significant increase in cell apoptosis rate). The expressions of cleaved PARP and caspase-8 increased, while the expression of pro-caspase-3 decreased, which further verified sodium aescinate's effect in inducing cell apoptosis. Sodium aescinate significantly inhibited the phosphorylation of cell survival-related signal molecules (AKT, ERK) and down-regulate the activation of their common up-stream kinase SRC. The findings indicated that sodium aescinate can block signals transiting to downstream molecules AKT, ERK, inhibit the proliferation of breast cancer cell MCF-7 cell apoptosis and induced cell apoptosis by suppressing the activation of SRC.
