Objective To study the relationship between throid hormone and chronic heart failure in patients and its clinical significance. Methods The free thriiodothyronine( FT3 ), the total thriiodothyronine(TT3 ), the free thyroxine(FT4 ), the total thyroxine (TT4 ), the rebellion thriiodothyronine ( rT3 ), the thyroid stimulating hormone (TSH) in 100 patients with chronic heart failure and 50 normal people were determined by particle glimmer. Results The levels of T3 in patients with chronic heart failure were markedly lower than those in normal controls;The heart failure in low thriiodothyronine state case was severe. Conclusion The level of T3 in elderly patients with chronic heart failure was decreased, and it was correlated with the severity of heart failure.

Objective To investigate the effect of oxycodone and sufentanil with equivalent dose on hemo-dynamics and stress response in general anesthesia induction. Methods One hundred and twenty ASA I orⅡpa-tients with abdominal surgery were randomly divided into oxycodone group(group O,n=60)and sufentanil group (group S,n = 60). Anesthesia was induced with iv oxycodone 0.20 mg/kg(group O)or sufentanil 0.25 μg/kg (group S)respectively,together with iv propofol 2.0 ~ 2.5 mg/kg and cisatracurium 0.2 mg/kg. The patients were tracheally intubated using a single-lumen endotracheal tube. Mean arterial pressure(MAP),heart rate(HR),plas-ma levels of epinephrine(E)and norepinephrine(NE),cortisol(Cor)and blood sugar(Glu)and the occurrence of bucking before anesthesia induction(T0),immediately before intubation(T1),at the moment of intubation(T2), 1 min(T3)and 5 min(T4)after intubation were observed. Results Compared with these at T0,MAP and HR in 2 groups were lower at T1(P<0.05)and no significant difference was found in 2 groups(P>0.05). MAP and HR were significantly higher at T2 and T3(P < 0.05)and compared with those in group O,MAP and HR in group S were increased more significantly at T2 and T3(P<0.05). MAP and HR increased slightly at T4 in 2 groups but no significant difference was found in 2 groups(P>0.05). Plasma levels of E ,NE,Cor and Glu increased obviously at T2 and T3 in 2 groups(P < 0.05)and they were even higher in group S(P < 0.05). Plasma levels of E ,NE , Cor and Glu increased slightly at T4 in 2 groups but no significant difference was found in 2 groups(P > 0.05). Conclusion Compared with sufentanil ,oxycodone of equivalent dose used for general anesthesia induction can effectively keep smooth on hemodynamics and decrease stress response.

At present,nutrition therapy plays a very important role in critically ill children,which can impact on the development and outcome of the disease by the process of metabolism and immunity.Immune-modulating nutrients,such as glutamine,which is a current hot topic,but now there is a little research in it in critically ill children,and this paper summarizes the approach,the dose and the efficacy of glutamine in critically ill children,aiming to offer reference in clinics.

OBJECTIVE:To study the pathogenic organism of sepsis in children with tumor and its drug sensitivity for references of clinical medication.METHODS:The drug sensitivity of hemoculture samples of children with neoplastic hema-tologic disorder was detected by paper disk method.RESULTS:Of the total109pathogenic bacteria isolated from hemoculture samples,60(55.0%)were gram-positive(G + )bacteria,47(43.1%)were gram-negative(G - )bacteria and2(1.8%)were fungi.Vancomycin,teicoplanin and aminoglycosides were more sensitive to G + bacteria,while carbopenems and cefoperazone/sulbactam were more sensitive to G - bacteria.CONCLUSIONS:In treating sepsis in children with tumor,the choice of drugs should be based on the drug sensitivity test,the possibility of G + and G - bacteria infections should be considered in empiric treatment and the possibility of mycotic infection should also be considered after long-term administration of antibacterials.

Objective To investigate the role of the clock gene promoter methylation in aging. Methods C57BL mice of 4- (young, n=9) and 20- (old, n=10) month-old were determined the promoter methylation level of clock genes (Per1/2, Bmal1/2, Cry1/2, Clock, Npas2) in the stomach, spleen, vascular, kidney and striatum with methylation-specific polymerase chain reaction (MSP). Results The incidence of promoter methylation of Cry1, Bmal2 and Npas2 in spleen increased in old mice (P<0.05), while the promoter methylation of Per1 in stomach decreased (P<0.05), and the promoter methylation of Bmal1 in vascular increased (P<0.05). Conclusion Promoter methylation of some clock genes is involved in process of aging in a tissue-specific way.

Purpose: To evaluate the clinical efficacy of V AD regimen in the treatment of newly diagnosed stage III multiple myeloma (MM). Methods:26 patients with newly diagnosed stage Ⅲ multiple myel oma were treated with VAD regimen. VAD solution consisted of vincristine (VCR) , doxorubicin(ADR),dexamethasone (Dex).Three continuous treatments in one treatm ent course were considered evaluable.Evaluation included results of serum myelom a protein(M-protein); renal function; proteinuria of 24-hours; bone marrow ; per ipheral blood et al.The side reactions were recorded. The clinical efficacy eval uation was divide into complete response(CR),partial response(PR),minimal-respon se(MR), no change(NC) , plateau progression.Results:5 cases achieved CR(19.3%), 13 cases PR(50%),6 case s MR (23%), 2 cases no change (7.7%). Overall response rate was 92.3%, median su rvival duration was 7 to 84 months (29.6?17months). Conclusions:Achieved marked clinical efficacy with VAD agent in newly diagnosed stage III multiple myeloma. Especially,the patients with renal failure and serious clinical manifestation improved rapidly and significantly.

Objective To investigate the clinical manifestations and possible mechanism of the multiple sclerosis (MS) combined with uveitis Methods Two cases of MS combined with uveitis were clinically observed by electro physiological, brain MRI and oligoclonic band (OB) examinations,the cases were analyzed and subjected to assessment Results Case1, a 56-year-old man had symptoms of one month′s numbness and twenty-day sudden decrease of visual acuity Viusal evoked potential (VEP)showed a postponed latent period of bilateral P100 waves Brain MRI showed multifocal T 2 Wight Image high signs in subcortical white matter of frontal and parietal lobes OB was postive Case 2: a 35-year-old woman, had recurrence of decrease of visual acuity of bilateral both eyes for 12 months and bilateral lower-limbs numbness Latent period of VEP P100 waves and BAEP I-V waves were postponed Brain MRI showed multifocal round-like T 2 Wight Image high signs in white matter of frontal and parietal lobes OB was postive Referring to the essay reported ,MS combined with uveitis was moetly moderate in manifestations Their causes were uncertain It is suggested that MS is not due to auto-antigen but due to S100-? protein derived from star-like cells Conclusion MS combined with uveitis ,unlike other one ,was clinically moderate and the pathological mechanism is unclear It is suggested that autoantigen such as S100-? protein derived from star-like cell results in MS and uveitis, not in MBP

0.05). The titrimetric determination of standard solution containing different levels of chloride showed recovery rates of 98.0%～103.7%, relative standard deviation was 0.16%. Conclusion Automatic potentiometric titration was easy to grasp, rapid and accurate, which was a new analytical method worthy to be applied extensively.

OBJECTIVE: To establish a RP-HPLC method for the simultaneous determination of Protocatechuic acid and Protocatechuic aldehyde in Fuxuekang granules. METHODS: The chromatography was carried on Achirom Bond-1 C18 column(250 mm?4.6 mm,5 ?m). The mobile phase was composed of methanol - water (20∶80,pH=2.80 adjusted by glacial acetic acid) at a flow rate of 1.0 mL?min-1. The detection wavelengths were programmed at 256 nm for Protocatechuic acid and at 280 nm for Protocatechuic aldehyde. RESULTS: The linear ranges for Protocatechuic acid and Protocatechuic aldehyde were 5.49～73.22 ?g?mL-1(r=0.999 9) and 4.81～64.13 ?g?mL-1(r=0.999 9), respectively, and their average recoveries were 96.86%(RSD=2.52%,n=9) and 97.55%(RSD=3.82%,n=9) respectively. CONCLUSION: The method is simple, sensitive, and reproducible, and it is applicable for the quality control of Fuxuekang granules.
