Objective To explore the clinical significance of dynamic determination of serum procalcitonin(PCT)levels in judgment of infection and prognosis in patients with severe craniocerebral injury.Methods A total of 80 patients with severe craniocerebral injury were selected and they were divided into infection group and non-infection group.Infection group was divided into improved group and non-improved group.Acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score and Glasgow coma scale(GCS)score was compared between infection group and non-infection group.The level of serum PCT,white blood cell count(WBC),C-reactive protein(CRP)and interleukin(IL)-6 was compared on the first,third,fifth day of admission in intensive care unit among these groups.Results Infection group in 48 patients,and non-infection group in 32 patients.There was no significant difference in age,sex and GCS score between two groups(P >0.05).APACHE Ⅱ score in infection group was higher than that in non-infection group [(21.71 ± 7.13)scores vs.(15.32 ± 6.17)scores],and there was significant difference (P< 0.05).The level of serum PCT on the first day of admission in intensive care unit in infection group was higher than that in non-infection group[(2.15 ± 1.79)ng/L vs.(0.56 ± 0.47)ng/L],and there was significant difference(P< 0.05).There was no significant difference in WBC,CRP and IL-6 between two groups(P>0.05).The level of serum PCT,WBC,CRP,IL-6 on the third day of admission in intensive care unit in infection group was higher than that in non-infection group,and there was significant difference(P< 0.05).The level of serum PCT on the fifth day of admission in intensive care unit in infection group was higher than that in non-infection group [(3.09 ± 1.98)ng/L vs.(1.06 ± 0.63)ng/L],and there was significant difference (P<0.05).WBC,CRP,IL-6 on the fifth day of admission in intensive care unit was(15.13 ±6.32)×109/L,(103.56 ±40.62)mg/L,(230.41 ± 121.83)ng/L in improved group(38 cases),and (18.62 ±8.89)× 109/L,(134.38 ± 34.16)mg/L,(268.73 ± 138.12)ng/L in non-improved group(10 cases),and there were significant differences between two groups(P < 0.05).The level of serum PCT on the first,third,fifth day of admission in intensive care unit in improved group was lower than that in non-improved group,and there was significant difference(P < 0.05).Conclusion The alteration of serum PCT level may be used as one of the effective predictors for infection in patients with severe craniocerebral injury and for their prognosis.

Journal of Acupuncture and Tuina Science 2007;5(4):234-237
To investigate the efficacy of the formula composed of the herbal drugs to soothe the liver, regulate qi, clarify the heart and eliminate vexation plus acupuncture for general anxiety disorder. Methods: Forty cases in the treatment group were treated with acupuncture plus herbal formula and 38 cases in the control group were treated with oral Doxepin. The assessment was conducted by Self-rating Anxiety Scale (SAS) and the Treatment Emergent Symptom Scale (TESS) before, during and after treatment. Results: The total effective rate was respectively 82.50% in the treatment group and 84.21% in the control group, with a significant difference in SAS assessment (P<0.01) between the two groups before and after the treatment.There were no significant differences in the curative and remarkable effective rate, total effective rate and SAS assessment between the two groups (P>0.05), but the side effect was higher in the control group than in the treatment group (P<0.01). Conclusion: Acupuncture plus herbal formula can have a precise effective effect for extensive anxiety neurosis with mild toxic side effects.

Objective To investigate the activation and role of signal transduction pathway of epidermal growth factor (EGF)-epidermal growth factor receptor (EGFR)-mitogen activated protein kinase (MAPK) in proliferation of human retinal pigment epithelial (RPE) cells. Methods Human RPE cells were stimulated with 0.1%,10% foetal calfserum (FCS) and EGF(0.1, 1, 10, 50 and 100 ng/ml)in 0.1% FCS Dulbeco′s modified Eagle′s medium (DMEM) and in 10% FCS DMEM for 3 days, respectively. Immunohistochemical staining and in situ hybridization were used to observe the expressions of EGFR protein and EGFR mRNA,respectively. Activation of MAPK was detected by immunohistochemical method with specific anti-phosphorylated ERK 1/2 antibody. Results The optimal concentrations of EGF were 10 ng/ml in 0.1% FCS DMEM and 1 ng/ml in 10% FCS DMEM. After 3 days of stimulation with EGF, phosphorylated ERK 1/2 staining was detectable in nucleus of RPE cells, whereas cells presented immunostaining for phosphorylated ERK 1/2 in the cytoplasm before stimulation. Conclusions EGF may improve the expression of EGFR protein and EGFR mRNA of RPE cells, and induced MAPK nuclear translocation in a concentration-dependent manner. EGF-EGFR-MAPK signal transduction pathway may play a key role in RPE cells proliferation, and serum exerts an important acceclerating function in the process.

Objective To primarily investigate the clinical value of analgesia/nociception index (ANI) in evaluating the analgesic effect during lobectomy performed via video-assisted thoracoscope.Methods Forty ASA physical status Ⅰ or Ⅱ patients,aged 25-64 yr,weighing 45-80 kg,undergoing elective lobectomy performed via video-assisted thoracoscope,were enrolled in this study.After induction of anesthesia with propofol,sufentanil and cisatracurium,patients received double lumen endotracheal intubation.Anesthesia was maintained with targetcontrolled infusion of propofol,and iv infusion of remifentanil and cisatracurium.The concentration of propofol was adjusted to maintain the bispectral index (BIS) value in the range of 40-60.ANI,HR,systolic blood pressure (SBP),diastolic blood pressure (DBP) and BIS value were recorded within 5 min before and after the predefined time points including posture change between lateral and supine position,ventilatory pattern change between onelung and double-lung ventilation,skin incision and trocars insertion,lymph node dissection and pleural lavage.At skin incision and during trocars insertion,lymph node dissection and pleural lavage,the development of hemodynamic responses (increase in HR and SBP > 20% of baseline value) were recorded.Results The incidence of hemodynamic responses was 100% at skin incision and trocars insertion,and 84 % during No.4,7,10 groups of lymph node dissection and after pleural lavage and difference was found in ANI during these stimuli.ANI was significantly decreased within 5 min after skin incision,trocars insertion,No.4,7,10 groups of lymph node dissection and pleural lavage than that before the procedures (P < 0.05).The BIS value was maintained at 40-60,and no significant changes were found between before and after the procedures (P > 0.05).No significant changes were found in ANI,HR,SBP,and DBP between before and after the changes of posture and respiratory pattern (P > 0.05).Conclusion ANI can be used to evaluate the analgesic effect during lobectomy performed via video-assisted thoracoscope in patients and is unaffected by the changes of posture and ventilatory pattern.
