Objective To observe changes of serum concentrations of interleukin-18(IL-18) and intercellular adhesion molecule-1(ICAM-1) in neonates with hypoxic-ischemic encephalopathy(HIE) and to explore the correlation of the 2 indices and its effect on patients′condition.Methods Thirty newborn infants met the criteria for HIE.There were 16 cases in mild HIE group,14 cases in moderate and severe HIE group.Twenty normal newborn infants were used as control group.The serum concentrations of IL-18 and ICAM-1 of HIE group and control group were detected using ELISA on the third day and 7th day.Results 1.The IL-18 levels of the mild,moderate and severe HIE and control groups measured within 3 days of life were (120.1?12.7),(175.1?15.4),(100.3?12.5) ng/L,respectively.The concentrations of IL-18 in HIE groups were higher than that of control group(Pa

Objective To evaluate the application of fibrobronchoscopy in the management of severe brain injury with concurrent pulmonary infection. Methods Forty-three procedures of fibrobronchoscopic sputum clearance or bronchoalvelar lavage were performed in 26 patients with severe brain injury and concurrent pulmonary infection. The effect of fibrobronchoscopic treatment was assessed by observing the changes in the respiratory symptoms, arterial oxygen saturation (SaO2) and partial pressure of oxygen (PaO2) in these patients. Results The symptoms of the respiratory system, SaO2, and PaO2 of the 26 patients were significantly improved after fibrobronchoscopic treatment, which caused no serious complications. Conclusion Fibrobronchoscopy can be safely and effectively used in patients with severe brain injury complicated by pulmonary infection.

Objective To assess the value of thickness and arterial resistive index (RI) of wrist synovium in differentiation from activity to non-activity of rheumatoid arthritis (RA). Methods Ninety-two clinically confirmed RA patients underwent high frequency ultrasonography. Maximum thickness and arterial RI of the wrist synovium were measured in active and nonactive stage. Results Thickened synovium was found in 75 of 92 patients. Color signal in the synovium was detected and then RI was measured in 67 patients, including 31 in active stage and 36 in nonactive stage. The wrist synovium thickness of 67 patients was (2.97±1.49) mm and arterial RI was 0.74±0.17. RI decreased significantly in patients in active stage compared with that in nonactive stage (P<0.001). Conclusion Arterial RI measurement with high frequency ultrasonography may be served as an objective marker of synovial membrane disease in RA. The thickness of synovium cannot predict the activity of RA.

OBJECTIVETo observe the effect of early bronchoscopic sputum suction in elderly patients with acute heart and lung failure due to aspiration pneumonia.

METHODSComprehensive treatments were administered for 52 elderly patients with acute heart and lung failure resulting from aspiration pneumonia, and in 27 of the patients, bronchoscopic sputum suction was performed with the other 25 serving as the control group. The indices of the heart and lung functions (central venous pressure, left ventricular ejection fraction, arterial blood partial pressures of oxygen and carbon dioxide) were measured after the treatment and compared between the two groups.

RESULTSPatients receiving bronchoscopic suction showed faster recovery of normal central venous pressure and left ventricular ejection fraction and more rapid increment of arterial partial pressure of oxygen and reduction of carbon dioxide partial pressure than those without the suction (P<0.01).

CONCLUSIONEarly bronchoscopic sputum suction can be one of the effective emergency measures for rescuing acute heart and lung failure due to aspiration pneumonia.

OBJECTIVE: To discuss the coding of full dentition with 32 locations and measure the characteristics of some bony indexes in occlusal-facial digital radiology (DR). METHODS: To select randomly three hundred DR orthopantomogram and code the full dentition, then analyze the diversity of dental patterns. To select randomly one hundred DR lateral cephalogram and measure six indexes (N-S,N-Me,Cd-Gn,Cd-Go,NP-SN,MP-SN) separately by one odontologist and one trained forensic graduate student, then calculate the coefficient variation (CV) of every index and take a correlation analysis for the consistency between two measurements. RESULTS: (1) The total diversity of 300 dental patterns was 75%.It was a very high value. (2)All six quantitative variables had comparatively high CV value.(3) After the linear correlation analysis between two measurements, all six coefficient correlations were close to 1. This indicated that the measurements were stable and consistent. CONCLUSION The method of coding full dentition in DR orthopantomogram and measuring six bony indexes in DR lateral cephalogram can be used to forensic identification.

OBJECTIVETo observe the efficacy of thread-moxa in Zhuang folk medicine (TM) combined with acupuncture and external application drugs for AIDS patients with herpes zoster (AHZ).

METHODSA randomized, controlled clinical trial was conducted in 60 patients with AHZ. They were randomly assigned to the treatment group (treated with TM combined with acupuncture and Jingwanhong Scald Ointment) and the control group (treated with Famciclovir Tablet, nimesulide dispersible tablet, vitamin B1, ribavirin ointment). The treatment course was 14 days for both groups.The clinical efficacy, significant efficiency visual analog scale score (VAS), sleep quality score (QS), the postherpetic neuralgia rate in 1 year after treatment were observed.

RESULTSThe markedly effective rate was significantly higher in the treatment group than in the control group (86.7% vs. 53.3%, P < 0.01). There was no statistical difference in the total effective rate between the two groups (96.7% vs. 80.0%, P > 0.05). The post-treatment VAS, QS, the time for pain disappearance, skin repair, crusting, and 1-year postherpetic neuralgia incidence rate were significantly lower in the treatment group than in the control group (P < 0. 05, P < 0.01).

CONCLUSIONSTM combined with acupuncture and Jingwanhong Scald Ointment was effective for treating AHZ patients. It relieved pain quickly, shortened their course of disease, and improved their quality of sleep.

OBJECTIVETo explore the effect of Panax notoginseng saponin (PNS) on the activity and content of beta-secretase in the brain of senescence accelerated mouse-prone 8 (SAMP8) mice with Alzheimer's disease.

METHODSTotally 32 SAMP8 mice were randomly divided into the normal control group, the high dose PNS group (200 mg/kg), the low dose group (100 mg/kg), and the huperzine A group (0.3 mg/kg), 8 in each group. Equal volume of double distilled water was given to those in the normal control group. All medication was given by gastrogavage, once daily for two successive months. The activity of BACE1 was assayed by direct immunofluorescent method (DIF). The content of BACE1 protein was detected by Western blot.

RESULTSThe relative fluorescence units (RFU/microg) was 2.008 +/- 0.031 in the high dose PNS group, 2.221 +/- 0.029 in the low dose PNS group, and 2.267 +/- 0.076 in the huperzine A group, all lower than that in the normal control group (2.403 +/- 0.058; all P < 0.01). The content of BACE1 protein was 0.900 +/- 0.028 in the high dose PNS group, 1.000 +/- 0.032 in the low dose PNS group, and 0.837 +/- 0.080 in the huperzine A group, all lower than that in the normal control group (2.210 +/- 0.074, all P < 0.01).

CONCLUSIONPNS higher than 100 mg/kg could decrease the activity of BACE1 and down-regulate the content of BACE1 protein in the brain of SAMP8 mice.

OBJECTIVETo explore the risk factors of road traffic injury (RTI), and to provide evidence for stretagy development on the prevention and control of RTI.

METHODSCase-crossover study was used. 402 drivers were face to face interviewed by specially designed questionnaire including the items as drinking alcohol before driving, onset anger scale (OAS), anxiety/irritation, Stanford sleepiness scale (SSS), vehicle breakdown, carelessness, violating the rules on right of way and traffic signs when driving. Tables related to case-control study on 1:1 matching was used for single factor analysis, and conditional logistic regression was used for multifactor analysis.

RESULTSThe risk factors that were associated with RTI including high OAS (OAS = 5-7, OR = 114.88, 95% CI:4.29-3074.86), violating the rules on right of way (OR = 46.96, 95% CI:12.74-173.11), violating traffic signs when driving(OR = 24.57, 95% CI: 8.69-69.45), carelessness (OR = 14. 54,95% CI: 6.85-30.86), unsafe distance between vehicles( OR = 14.30,95% CI: 3.68-55.60), wrong judgement (OR = 14.67,95% CI:4.88-44.10), vehicle breakdown (OR = 8.57, 95% CI: 1.38- 53.27) and improper measure ( OR = 8.46, 95% CI: 2.46-29.14) etc.

CONCLUSIONImproper driving behaviors, abnormal psychological status and driving skills of drivers were related to RTI, suggesting that it was necessary to carry out continous traffic security education to the drivers.
