Objective To investigate the value of C- reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-?) in early diagnosis of neonatal sepsis. Methods Sixty- five newborns were divided into experiment group and control group, experiment group was also divided into sure group and doubtful group by blood culture We assessed the level of serum CRP, IL-6 and TNF-? in 24 hours and after 24 hours of clinical diagnosis of sepsis in experiment group, and examined the blood culture before antibiotic treatment Serum CRP, IL-6 and TNF-? were also examined in 3 to 6 days old. Results 1 The levels of serum CRP, IL-6 and TNF-? in experiment group were significantly higher than that in control group 2. The sensitivity of IL-6 and TNF-? were higher than CRP in 24 hours in experiment group. 3. After 24 hours, the sensitivity of CRP was elevated,and there was no statistical difference compared with the IL-6. Conclusion IL-6 and TNF-? are the credible marker in the early diagnosis of neonatal sepsis, and are more sensitive than the CRP, the IL-6 is the first sensitive marker.

Procalcionin ( PCT) is a soluble protein liberated into the circulation of patients in response to severe systemic in-fection, in particular by bacterial infection.It is used as the most accurate biomarker for the diagnosis of sepsis.This review briefly de-scribes the induction of PCT, the comparison of PCT and other markers of sepsis, the application of PCT measurement in confirmation or exclusion of diagnosis of sepsis, the assessment of severity and treatment effectiveness of systemic infection, the application of PCT in guiding individual and specific treatment of antibiotics, and the anormaly situation of elevated levels of PCT in patients who do not have sepsis.

Objective To raise the awareness of the glandularis ureteritis. Methods Five cases with glandularis ureteritis confirmed by pathological examination from Jan 2001 to Jun 2012 were reviewed. The diagnosis was assessed on histopathologic studies in all. The clinical manifestations, the diagnosis and treatment were discussed. Results Resections of the affected ureter and ureteroplasty were undertaken for 2 patients. Ureteronephrectomy was performed for 2 patients because of serious hydronephrosis due to obstruction. Electrofulguration via-ureteroscopy was carried out for another patient. All patients have been well and without recurrence on following up for 15 to 152 months, with an average of 86.6 months. Conclusion Glandularis ureteritis is not frequently seen and the etiopathogenesis is not yet clear. Biopsy is very important for suspected neoplasm of ureter before performing nephrectomy.

Objective To explore the role of Annexin Ⅱ and urokinase-type plasminogen activator(uPA) proteins in the development and lymph node metastasis of thyroid cancer.Methods Immunohistochemistry was used to detect the expression of Annexin Ⅱ and uPA proteins in 35 cases of papillary thyroid cancer tissues,10 cases of thyroid adenoma tissues,16 cases of nodular goiter tissues and 7 cases of normal thyroid tissues.Results The positive expression rate of Annexin Ⅱ and uPA protein was significantly higher in papillary thyroid cancer than in normal thyroid tissues,nodular goiter tissues and thyroid adenoma tissues( P ＜0.05 ).The expression of Annexin Ⅱ and uPA protein was positively correlated in papillary thyroid cancer tissues(P ＜0.05).The expression of Annexin Ⅱ protein in thyroid cancer tissues was associated with tumor size and lymph node metastasis while the expression of uPA protein was only related to lymph node metastasis.Conclusions Annexin Ⅱ and uPA proteins are involved in the occurrence and development of papillary thyroid cancer.They also play a facilitating role in lymph node metastasis of papillary thyroid cancer.

[ ABSTRACT] AIM:To observe the effect of endogenous nitric oxide synthase ( NOS) inhibitor asymmetric dimeth-ylarginine ( ADMA ) and its signaling pathways on NO levels and skeletal muscle contractility in 4-week running rats. METHODS:The 4 weeks running rat model was established.The twitch tension, tetanic tension and the fatigue test of sole-us muscle induced by electrical stimulation ex vivo were detected.The ATP content, mitochondrial DNA levels and the mR-NA expression of peroxisome proliferator-activated receptor γcoactivator-1α(PGC-1α), nuclear respiratory factor (NRF) were measured to reflect the mitochondrial function and biosynthesis in the skeletal muscle.Serum ADMA concentration was detected by high performance liquid chromatography.The endogenous ADMA enzymes PRMT1 and 2 subtypes of ADMA me-tabolism enzyme DDAH, 3 subtypes of NOS protein expression in the skeletal muscle were determined by Western blot.NOS activity and nitric oxide ( NO) content were analyzed by colorimetric method.RESULTS: Compared with normal control group, the twitch tension, tetanic tension and the anti-fatigue capability of soleus muscle in running group were significantly enhanced, ATP content, mitochondrial DNA content and the mRNA expression of PGC-1αand NRF were significantly in-creased (P<0.01).In addition, the protein expression of constitute type NOS (cNOS) and NOS activity were significantly increased (P<0.01), but the increase in NO content was relatively smaller in soleus muscle in exercise group (P<0.05). Moreover, serum ADMA concentration in running group was increased, while the DDAH2 expression in skeletal muscle was decreased.CONCLUSION:Short-term endurance exercise enhances the twitch tension, tetanic tension and fatigue resist-
ance of soleus muscle.The mechanism may be that increased cNOS expression feedbacks to increase ADMA concentration, thus maintaining the increase in NO synthesis at a relatively low level, and resulting in promoting skeletal muscle mitochon-dria biosynthesis and mitochondrial function.

OBJECTIVE:To explore the effects of Bushen huoxue huatan decoction on ovarian blood supply and form in model rats with polycystic ovarian syndrome(PCOS). METHODS:50 SD female rats were randomized into normal control group,model group,positive control group [rosiglitazone,3 mg/(kg·d)],Bushen huoxue huatan decoction low-dose and high-dose groups [5.0, 7.5 g/(kg·d)],with 10 rats in each group. Except for normal control group,PCOS model was induced in the other groups by Poresky method. After modeling,treatment groups were given relevant medicine intragastrically. The normal control group and mod-el group were given normal saline [10 mL/(kg·d)] intragastrically,once a day,for 22 days. After the end of administration,the rats were sacrificed. The microvessel density (MVD) was recorded. mRNA expression of vascular endothelial growth factor (VEGF), ovarian angiotensin Ⅱ receptor(Ang Ⅱ)type 1(AT1)and type 2(AT2),G-protein coupled receptor MAS were all detected in ovarian tissue of rats. The ovarian form was observed. RESULTS:Compared with normal control group,MVD of mod-el group and treatment groups were all increased,while mRNA expression of AT1,AT2 and MAS were down-regulated (P<0.05);cystic sinus sollicle,the decrease of granular cell layer,egg mother cells disappearance,the decrease of luteal tissue and other obvious pathological changes could be found in ovarian tissue of rats in model group. Compared with model group,above in-dexes of treatment groups were improved significantly,and the effects of Bushen huoxue huatan decoction low-dose and high-dose groups were better than that of positive control group (P<0.05). The pathological changes of ovarian tissue in treatment groups were all improved to certain extent. CONCLUSIONS:Bushen huoxue huatan decoction can improve ovarian blood supply,angio-genesis and ovulation in PCOS rats. It is beneficial to improve ovarian form.

The cholesterol esterase and its oxidase were respectively immobilized onto sol-gel(tetraethyl orthosilicate)and then an enzymatic reaction column was prepared. Hydrolysis of cholesterol ester took place in the presence of cholesterol esterase to form cholesterol under catalysis of cholesterol oxidase, and Cholesterol was oxidized to produce hydrogen peroxide which reacted with luminal in the presence of simulated enzyme hemoglobin to result in the emission of light. Thereupon, a chemiluminescence system combined with flow injection technology by sol-gel immobilized enzyme was developed for the determination of cholesterol including free and total amount in human serum. The CL intensity was well linear with the concentration of cholesterol;liner range of total and free cholesterol was 1.01×10~(-6)～2.02×10~(-4) mol/L with a detection limit of 7.5×10~(-7) mol/L) and 5.0×10~(-8)～2.18×10~(-5) mol/L) with a detection limit of 5.0×10~(-9) mol/L respectively. Contrasted the method) with the biochemical analyzer (TBA-120FR), both the methods had no significant difference. This method has been successfully applied for the detection of cholesterol in clinic serum samples.
