Objective:To investigate the correlation between serum CXCL10 level and the severity of obstructive sleep apnea syndrome(OSAS) in male patients.Methods:52 male patients and 41 control volunteers were enrolled.Polysomnography was processed to monitor the AHI scores.Serum CXCL10 level was determined by ELISA.The correlation between serum CXCL10 level and AHI scores was analyzed statistically.Results:Serum CXCL10 level(ng/ml) in the OSAS groups was significantly higher than that in the control group [99.18 (70.46-158.01) vs 64.13 (53.5-73.6),P ＜ 0.001].Multivariate logistic regression analysis demonstrated that serum CXCL10 level was the only independent predictor of OSAS(OR:1.021;95％ CI:1.009-1.035;P ＜0.001).The serum CXCL10 level was positively correlated with the severity of OSAS [CXCL10 level in mild OSAS:82.7 (56.76-145.51);in moderate:OSAS 113.28 (87.15-162.67)].Serum CXCL10 level was independently correlated with AHI scores(r =0.476,P ＜ 0.001).Conclusion:Serum CXCL10 level was independently associated with the occurrence and the severity of OSAS.Serum CXCL10 level can be used as a biomarker to diagnose the OSAS and further to assess the severity of OSAS.

Objective To study the expression and significance of vascular endothelial growth factor(VEGF) in serum of umbilical blood from the newborns of women with severe pre-eclampsia.Methods Radioimmunoassay was used to measure the serum VEGF of umbilical blood from 26 newborns of women with severe pre-eclampsia (severe pre-eclmpsia group) and 30 newborns of normal pregnancy women (control group). According to birth weight-gestational age relation,severe pre-eclampsia group included 15 newborns small for gestational age (SGA group) and 11 newborns appropriate for gestational age (AGA group).Results (1)The VEGF level of umbilical vein blood and umbilical artery blood in severe pre-eclmpsia group was significantly higher than that in control group respectively(t = 2.16, P < 0.05;t = 4.82, P < 0.01). (2) In control group and severe pre-eclampsia group, the VEGF level in umbilical artery blood was significantly higher than that in umbilical vein blood (control group: t = 2.24, P < 0.05;severe pre-eclampsia group: t = 3.00, P < 0.01). (3)In both control group and severe pre-eclampsia group, there was no significant correlation respectively between VEGF levels in umbilical vein blood or umbilical artery blood and newborns' gestational age or birth weight. (4)VEGF level of umbilical artery blood in SGA group was significantly higher than that in AGA group as well as in control group(t = 3.22, P < 0.01 ;t = 6.80, P < 0.01). Conclusions The serum VEGF level of umbilical vein blood and umbilical artery blood from the newborns of women with severe pre-eclampsia was significantly higher than that of normal pregnancy women respectively. The VEGF level of umbilical artery blood can reflect the severity degree of the damage of hypertensive disorder complicating pregnancy to their newborns to some degree.

Objective To evaluate the surgical treatment of bladder cancer near ureteral orifice. Methods 42 cases of bladder cancer requiring ureteral reimplantation were divided into two groups at random:20 cases in group A:tongue-shaped incision of bladder wall around ureteral orifice was performed to modify Huctch-Ⅱ ureter implantation and 22 cases in group B:severing the ureter just outside the bladder,the ureter was then implanted into the bladder after partial cystectomy.Duration of the procedure,blood loss,amount of post-operation drainage,early complication,bladder ureter reflux,ureter obstruction,and cancer recurrence rate were studied and compared. Results In group A,the surgery took 60.5?18.5 min,blood loss amounted to 50.6?12.8 ml and the post-operative drainage 50.6?17.8 ml.In group B,the operation needed 150.9?22.4 min,the blood loss amounted to 220.5?28.2ml and post-operative drainage 280.6?58.9 ml.All the above three indexes showed siginificant difference between the 2 groups (P0.05). Conclusions Tongue-shaped incision of bladder wall around the ureteral orifice better with less complication,technically easier and worth recommendation.

A comparison of effectiveness of chemo-immunotherapy (CIT) using LAK/CD3AK 1-2 weeks after TACE in 74 patients with no surgical indication and TACE alone in 41 patients with moderately advanced HCC was carried out. The rates of remission between CIT group and TACE alone group were 72.4% and 40.4%(P

To investigate the effect of propofol on the plasma contents of endothelin(ET) and calcitonin gene related peptide(CGRP).Twelve monkeys with hemorrhagic shock were divided randomly into two groups.The monkeys in propofol group(PG) were administered propofol to 8mg/L plasma concentration by target control infusion with computer,while monkeys in control group(CG) were not .Venous blood were collected to determine plasma ET and CGRP contents by radioimmunoassay before bleeding, 2 hours after hemorrhagic shock and 2h after resuscitation. Compared with control group,the CGRP level and CGRP/ET of PG were significantly increased at 2h after hemorrhagic shock and 2h after resuscitation,while ET level of PG at 2h after resuscitation was significantly lower than that of CG. These findings indicate that propofol can increase the plasma content of CGRP and decrease the plasma content of ET in monkeys after hemorrhagic shock and resuscitation, and ET may play an important role in the development of hemorrhagic shock.

Objective:To observe the clinically curative effects of Qingwen Baidu drink(清瘟败毒饮) on epidemic hemorrhagic fever (EHF).Methods:One hundred and eighty cases with EHF who were admitted to hospital within 5 days after onset were randomly divided into two groups.The control group (n=60) was treated with Ribavirin infused intravenously and liquid therapy,and treating complications simultaneously,meanwhile the treated group (n=120) based on the same therapy as control group treated with Qingwen Baidu drink number Ⅰ,Ⅱ or Ⅲtaken orally two times a day according to different course.Results:In treated group all the days of fever,polyuria,recovering platelet to normal,and transforming proteinuria to negative were significantly shorter than those in control group (both P<0.01),otherwise the overphase rates of oliguria and hypotension shock were higher than those in control group too (all P<0.01).The occurance rate of complications in treated group was lower than that in control group(P<0.05).Conclusions:The curative effects adding Qingwen Baidu drink on EHF are significant and worth spreading.

Objective To devise an improved double J tube for ureteral stenting so as to simplify its postoperative removal. Methods One end of the double J tube was made blind and got through the urinary tract via the ureteral wall or via a weak point of the renal cortex.The blind end was then embeded in the subcutaneous tissue and the ureteral stent was left behind for 4～12 weeks.A small incision (0.5 cm) was made in order to withdraw the stent and cystoscopy could be avoided.The self devised tube has been clinically employed for 60 cases. Results The stent has been satisfactory in all the 60 cases and its postoperative removal has been easy with no need of cystoscopy. Conclusions The subcutaneous embedding of a blind end of double J tube is simple and effective and its postoperative withdrawal is easy with no need of cystoscopy.

Objective:To study the effect of GABA and A receptor agonist THIP on proliferation and apoptosis of cytokine-induced killer (CIK) cells.Methods:CIK cells were cultured by routine method,and then treated with different concentrations of GABA and THIP.The proliferation of CIK cells were investigated by MTT assay.The apoptosis,cell cycle and immunophenotype were investigated by flow cytometry.Results:GABA could inhibit the proliferation of CIK cells in a dose-dependent manner and affect the distribution of cell cycle of CIK cells(P

An efficient technique for the determination of multiclass pesticide residues ( glyphosate, aminomethyl phosphonic acid ( AMPA) and glufosinate) in four kinds of tea ( green tea, black tea, Oolong tea and Puer tea) was developed based on ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Samples were extracted with 0. 05 mol/L NaOH solution, regulated pH value with HCl, followed by purification by Oasis HLB column, and then precolumn-derived with 9-fluorenylmethyl chloroformate ( FMOC-CL ) in borate buffer. All pesticide residues studied showed good linearity with correlation coefficient ( R2 ) greater than 0. 99 in the concentration range of 5-1000 μg/L. Limits of quantitation (LOQs) of three pesticide compounds ranged from 0. 03 to 0. 08 mg/kg (S/N=10). Tea samples spiked with 0 . 1 , 0 . 4 and 4 mg/kg showed the recovery ranging from 72 . 1% to 109 . 9%, and RSDs from 0. 5% to 9. 8% (n=6). In addition, the validated method was applied to commercial samples, and all the detections were confirmed by acquiring transitions for each pesticide in samples.
