BACKGROUND: Whether horizontal and vertical impacts cause craniocerebral injury of the same degree, and whether serum myelin basic protein (MBP) changes is associated with the direction of impact have been scarcely addressed in previous studies.OBJECTIVE: To observe the change in the serum MBP levels and morphological changes of the brain tissue rabbits with craniocerebral injury resulting from impacts from different directions.DESIGN: A randomized controlled experiment.SETTING: Department of Neurosurgery of a hospital affiliated to a medical university.MATERIALS: This study was conducted in the Central Laboratory of Shenyang Medical College between October 2003 and January 2004. Totally 30 healthy rabbits of either sex were randomly divided into two equal groups to receive vertical and horizontal impact on the head.METHODS: All the rabbits were anesthetized and fixed in prone position onto a table equipped with a device for inducing impact on the head from different directions. Venous blood of 1 mL was taken from the edge of the ear of each rabbit for detecting MBP before injury. The rabbits in vertical impact group received the impact of a hammer falling directly on the parietal bone of the skull. In the horizontal group, the rabbits were subjected to horizontal impact on the lateral side of the skull. Forty-eight hours after the injury, venous blood were again taken for MBP measurement. The rabbits were then killed for pathological examination of the brain.MAIN OUTCOME MEASURES: Changes in serum MBP and pathomorphology of the brain tissues in the two groups after the impact.RESULTS: ① According to intention to treat analysis, all the 30 animals were involved in the experiment. There was no significant difference in serum MBP levels between the two groups before the impact, nor 48 hours after the impact( P ＞ 0.05). In the vertical impact group, serum MBP levels before the impact was( 1.68 ± 0. 86) μg/L, which was significantly lower than that after the impact[ (5.25 ± 1.96) μg/L, t = 3. 226, P ＜ 0. 05]. ② In the horizontal strike group, serum MBP also significantly increased from the level of( 1.70 ± 0.91 ) μg/L before impact to(5.73 ± 2.07) μg/L after that( t = 3. 080, P ＜ 0.05) . ③ After the impact, vasodilation and congestion in the cortex near the midline of the bilateral parietal region and edema in the deep layer of the white matter were observed in the vertical impact group, along with significant enlargement of the extravascular and extracellular space. In the horizontal group, similar changes except those near the midline of the bilateral parietal region took place after the impact; the same pathological changes were also observed in the basal plane, with nearly identical pathological changes in the deep layer of the white matter.CONCLUSION: Vertical and horizontal impacts can both result in almost identical brain injuries demonstrated by similar changes in serum MBP and the pathomorphology of the brain tissues after the impacts.

Objective To study the time distribution of non-agriculture employed population spent in a working day in China, and to provide basic information for intervention strategies.Methods The data of 2002 China Nutrition and Health Survey were used. The information on daily activities including occupation,transportation,exercise,housework,sedentary activity and sleep was described.Results Non-agriculture employed population spent 8.41 h,0.58 h,0.09 h,3.11 h,1.40 h and 7.89 h on occupation, transportation,exercise,sedentary activity,housework and sleep,respectively.Administrator,technologist and clerks spent less time on occupation activity than service workers,production and transportation workers and others did,and they spent more time on sedentary activity.Male spent more time on occupation activity and less time on housework and sleep than female did.People in rural area spent more time on occupation activity than those in urban area,but less time On transportation and sedentary activity.Conclusion Differences in time use among different employed groups,gender and area were found,which should be considered when intervention measure is developed.

Objective To improve the accuracy with magnetic resonance imaging (MRI) diagnosis of spontaneous intraocular hemorrhage. Design Retrospective case series. Participants 6 patients with spontaneous intraocular hemorrhage. Methods The image findings were retrospectively analyzed in 6 patients confirmed by surgery with or without pathology. All of them were examined with ultrasonography and 5 cases with color ultrasonography. MRI was performed in 6 cases,and enhanced MRI in 5 cases. Main Outcome Measures Configuration,signal intense,characteristics of enhancement signal and ultrasonograph. Results 1 case was crescent shape on MRI of spontaneous intraocular hemorrhage,2 cases were lenticular shape,3 cases were hump shape. 2 cases showed high signal intensity on T1WI,and low signal on T2WI. 2 cases showed high signal on both T1 and T2WI. 2 cases showed low signal on T1WI,and high signal intensity on T2WI. 2 cases presented a ring with hypointensity on T2WI. No enhancement was revealed within the lesions in 5 cases. Liner enhancement was showed in 2 cases; ring enhancement was showed in 1 case. 2 cases were corrected diagnosed by MRI,2 cases were misdiagnosed as melanoma,and 2 cases were misdiagnosed as tumor concomitant hemorrhage,and all cases were diagnosed as tumor with ultrasonography. With color Doppler imaging 4 cases were correctly diagnosed as hemorrhage based on without blood-flow signal,and 1 case was diagnosed as tumor. Conclusions The MRI signal characteristic of spontaneous ocular hemorrhage is variable,and the main feature is no enhancement within the lesion. MRI combined with ultrasonography can make the diagnosis more correctly.

AIMTo explore the role of endogenous and exogenous hydrogen sulfide (H2S) in lipopolysaccharide (LPS)-induced acute lung injury (ALI) in rats and the underlying mechanisms.

METHODS120 Sprague-Dawley rats were randomly divided into four groups: control, LPS (instilled intratracheally to induce ALI), NaHS (H2S donor) + LPS, and propargylglycin (PPG) + LPS. Animals were sacrificed at 4 h or 8 h after agent administration. Lung weight/body weight ratio (LW/BW) was measured and calculated. Morphological changes of lung tissues were observed. H2S concentration, NO concentration (NO) and carbon monoxide (CO) level in plasma were tested. Malondialdehyde (MDA) content, CSE activity, inducible nitric oxide synthase (iNOS) activity and hemeoxygenase (HO) activity of the lung were determined. PMN and protein content in BALF were also tested. Immunohistochemisty technique was performed to examine the expression of iNOS and HO-1 protein in lung tissues. The correlation of H2S content with the above indices was analyzed.

RESULTSCompared with control conditions, severe injuries of lung tissues and a raised LW/BW, MDA content, PMN and protein content in BALF were observed in rats treated with LPS. LPS also lead to a drop in plasma H2S concentration and lung CSE activity. The enzyme activity of iNOS and HO, the protein expression of them and plasma NO, CO level increased after LPS instillation. Administration of NaHS before LPS could attenuated the changes induced by LPS. Pre-administration of PPG exacerbated the injuries induced by LPS, increased PMN and protein content in BALF, the plasma NO level, lung iNOS activity and its protein expression, but there was no prominent variation in CO level, HO activity and HO-1 protein expression compared with those of LPS group. The H2S content was positively correlated with CSE activity, CO content and HO-1activity (r = 0.945-0.987, P < 0.01), and negatively correlated with the other indices (r = -0.994 - -0.943, P < 0.01).

CONCLUSIONDownregulation of H2S/CSE was involved in the pathogenesis of acute lung injury induced by LPS. Endogenous and exogenous H2S provided protection against the lung injuries, which might be explained by its anti-oxidative effects, attenuating inflammatory over-reaction in lung induced by PMN,the downregulation NO/iNOS system and the upregulation of CO/HO-1 system.

Objective: To observe the clinical efficacy of acupuncture plus navel acupuncture for patients with urinary retention after radical hysterectomy for cervical cancer. Methods: A total of 64 patients with urinary retention after radical hysterectomy for cervical cancer was divided into a navel acupuncture group (22 cases), an acupuncture group (18 cases) and an acupuncture plus navel acupuncture group (24 cases). All three groups received bladder function training and neuromuscular electrical stimulation. In addition, navel points were combined in the navel acupuncture group. Electroacupuncture was conducted to Qihai (CV 6), Zhongji (CV 3), Dahe (KI 12), Shuidao (ST 28), Ciliao (BL 32) and Huiyang (BL 35) in the acupuncture group. The acupuncture plus navel acupuncture group received both treatments. The catheter was removed after 3 d of treatment. Spontaneous urination, residual urine volume, urinary catheter dependence and recurrence after 3 d, 6 d and 9 d of treatment in each group were observed, respectively. Results: In the acupuncture plus navel acupuncture group, the markedly effective rates after 3 d, 6 d and 9 d of treatment were significantly higher than those in the navel acupuncture group and the acupuncture group; the urinary catheter dependence was lower than that of the other two groups, and the differences were statistically significant (P<0.05, P<0.01); the spontaneous urination time was shorter than that of the navel acupuncture group and the acupuncture group, and the differences were statistically significant (P<0.05, P<0.01); the residual urine volume was significantly less than that of the navel acupuncture group and the acupuncture group, and the differences were statistically significant (both P<0.01). After the catheter was removed, recurrence was observed from the next day after spontaneous urination was resumed. There were 2 cases of recurrence in the navel acupuncture group, 2 cases in the acupuncture group and 1 case in the acupuncture plus navel acupuncture group. The recurrence rate of the acupuncture plus navel acupuncture group was significantly lower than that of the navel acupuncture group and the acupuncture group (both P<0.01). Conclusion: Acupuncture plus navel acupuncture has satisfactory efficacy for urinary retention after radical hysterectomy for cervical cancer. It can significantly shorten the urinary retention time, reduce the patient's dependence on urinary catheter, and reduce the residual urine volume.
