OBJECTIVETo study the curative effect of wilsonii injecta on severe head injury (SHI).
METHODSA total of 120 patients with SHI were divided randomly into 2 groups, the patients treated with conventional methods as Group A (n=60) and the patients treated with wilsonii injecta as Group B (n=60). The changes of neural function indexes were evaluated with Glasgow Coma Scale (GCS) before treatment and with Glasgow Outcome Scale (GOS) after treatment, simultaneously, the parameters of hemorrheological indexes (HI), brain electrical activity map (BEAM) and transcranial Doppler sonography (TCD) were observed before and after treatment.
RESULTSIn Group B, the clinical GCS, the HI, the BEAM and the prognosis GOS were improved much more than those in Group A. And the TCD parameters in Group B decreased, which had significant difference compared with that in Group A (P<0.01).
CONCLUSIONSWilsonii injecta can rapidly improve the injured p ersons' conscious states, the abnormal BEAM and the surviving quality. It suggests that the improvement of the HI is related to the relief of the vasospasm of the arterial blood vessels in the brain, which may be one of the important mechanisms of wilsonii injecta in improving the prognosis.

OBJECTIVETo summarize anesthetic management of low birth weight infants undergoing surgical intervention of congenital heart disease without cardiopulmonary bypass.
METHODSFifty-three low birth weight infants (including 49 premature infants) with congenital heart disease underwent surgical treatment without cardiopulmonary bypass during the period from June, 2003 to July, 2013. The mean gestational age of the infants was 30.96∓3.09 weeks (26-40 weeks) with a mean age on the operation day of 32.81∓20.76 days (4-87 days), birth weight of 1429.90∓455.08 g (640-2460 g), and weight on the operation day of 1750.20∓481.59 g (650-2460 g). All the infants underwent cardiac operations without cardiopulmonary bypass under general anesthesia. The respiratory parameters and acid-base and electrolyte balance were adjusted according to blood gas analysis. The inotropic drug was used to maintain the hemodynamic stability.
RESULTSForty-seven of the infants received patent ductus arteriosus (PDA) ligation. Of these infants, 1 had cardiac arrest before the operation with failed cardiopulmonary resuscitation, and in another case, PDA ligation was aborted due to severe hypoplasia of the aortic valve and ascending aorta found intraoperatively by transesophageal echocardiography. Two infants underwent coarctation of the aorta (CoA), and 1 of them died during the operation due to cardiac arrest. The total mortality of these infants was 3.77% and the early postoperative mortality (<72 h) was 5.66%.
CONCLUSIONSNon-cardiopulmonary bypass surgery can be performed in low birth weight infants in early stage, and effective anesthetic management can reduce the perioperative mortality and improve the postoperative survival rate.

Objective:To explore combined detection of mad2 with anti-nuclear mitotic spindle apparatus antibody(MSA)and anti-centromere antibody(ACA)and their clinical value for the diagnosis of small cell lung cancer(SCLC).Methods:One hundred and twen-ty SCLC patients,110 non-small cell lung cancer(NSCLC)patients,and 115 pulmonary nodule(PN)patients were enrolled in this study. The expression of mad2 was analyzed by qt-PCR.MSA and ACA were detected by indirect immunofluorescence(IIF)staining.Results:mad2 was overexpressed in SCLC and NSCLC samples(P<0.05).There were significant differences between the results obtained for SCLC and NSCLC samples by qt-PCR(P<0.05).AUC in ROC curve for mad2 expression was 0.799 with an intermediate diagnostic value. In the correlative analysis,the odds ratio of MSA and ACA was 6.94 and 5.60,respectively.In the correlation analysis,Kappa value of mad2 with MSA was 0.49,and Kappa value of mad2 with ACA was 0.42.In the parallel analysis,the sensitivity and specificity was 83.31% and 79.34%,respectively,while the Youden Index was 0.62.Moreover,in the serial analysis,the sensitivity and specificity was 65.32% and 93.35%,respectively,and the Youden Index was 0.59.Conclusions:In comparison with the NSCLC and PN samples,mad2 was overexpressed in SCLC samples.Therefore,mad2 ought to play a critical role in the pathology of SCLC.The combined expression of mad2 with MSA and ACA may contribute to enhancing the sensitivity and specificity of detection;this expression may allow early diag-nosis and clinical diagnosis of SLCC and may be a promising treatment for SCLC.

Objective:To explore the differences of clinical features and surgical efficacy between the elderly and the middle-aged and young patients with meningiomas in the central cortex area.Methods:Forty-three elderly patients with meningiomas in the central cortex area (≥60 years old) and 63 middle-aged and young patients with meningiomas in the central cortex area (18-59 years old), accepted surgery in Department of Neurosurgery, Guangdong 999 Brain Hospital from January 2011 to December 2020, were chosen. The differences of symptom, gross tumor volume, peritumoral edema degrees, intraoperative blood loss, tumor resection degrees, complications, and hospital stays between the 2 groups were analyzed.Results:The elderly patients had significantly higher proportion of preoperative muscle strength decline, lower proportion of preoperative headache, larger preoperative tumor volume, more severe peritumoral edema degrees before and after surgery, small volume of intraoperative blood loss, and longer hospital stays compared with the middle-aged and young patients ( P<0.05). However, no significant differences in distributions of tumor resection Simpson grades, proportion of new neurological dysfunction, incidence of postoperative complications, and proportions of reoperations and tumor recurrence were noted between the 2 groups ( P>0.05). Significant difference in distributions of peritumoral edema degrees among patients with different WHO grades was noted in the elderly group ( P<0.05), and significant difference in distribution of peritumoral edema degrees among patients with different tumor volumes was noted in the middle-aged and young group ( P<0.05). Conclusions:Although differences in clinical characteristics exist between the elderly and the middle-aged and young patients with meningiomas in the central cortex area, no significant difference in surgical efficacy is noted between the 2 groups. The peritumoral edema degree in the elderly patients is related to tumor pathological grades, while that in middle-aged and young patients is related to tumor volumes.

OBJECTIVETo perform a sampling survey of occupational hazard in typical industrial enterprises in Guangzhou, China, by means of sentinel surveillance, to understand the classification, distribution, and concentration/intensity of occupational hazard as well as the characteristics and development of occupational health management in Guangzhou, and to provide a scientific basis for occupational health supervision.
METHODSFifteen enterprises in information technology (IT), shipbuilding, chemical, leather and footwear, and auto repair industries were enrolled as subjects. Dynamic surveillance for occupational hazard and occupational health management was performed in workplaces of those enterprises.
RESULTSThe overall overproof rate of occupational hazard in the 15 sentinel enterprises from 2012 to 2014 was 6.16% (45/731). There was no significant difference in the overproof rate between the three years (P > 0.05). During the three years, enterprises in shipbuilding industry had significant higher overproof rates than those in other industries (P < 0.05). According to the results of occupational health management questionnaire, the overall coincidence rate of survey items was 57.88% (393/679); enterprises in IT industry had significant lower coincidence rates than those in other industries in 2012 and 2014 (47.62%, 29.63%; P < 0.05), while enterprises in leather and footwear industry had significant lower coincidence rates than those in other industries in 2013 (40.63%; P < 0.05).
CONCLUSIONThe enterprises in shipbuilding industry are the key to the prevention and control of occupational hazard in Guangzhou. To strengthen surveillance for occupational health in workplaces in Guangzhou, it is important to enhance occupation health supervision among small and micro enterprises and develop continuous sentinel surveillance for occupational hazard in key industries.
