BACKGROUND:Some scholars suggest that the nerve root palsy after cervical spinal stenosis treated with
decompression and implant internal fixation is related with the cervical stability and cervical lordosis, but there is controversial.
OBJECTIVE:To explore the C 5 nerve root palsy and stability after cervical spinal stenosis treated with posterior laminectomy lateral mass fixation and single-door decompression laminoplasty.
METHODS:Twenty-nine cervical spinal stenosis patients were selected and treated with posterior
decompression and implant internal fixation. Posterior laminectomy lateral mass fixation for the treatment of
cervical spinal stenosis:C3-6 lateral mass and C7 pedicel screw internal fixation was performed and caused rough surface on the facet joint;the unstable segment was confirmed according to the preoperative anteraposterior
plain film and dynamic radiographs combined with MRI and CT images, and then the corresponding segments were treated with lateral mass internal fixation, single-door decompression laminoplasty and laminoplasty.
RESULTS AND CONCLUSION:Al the 29 cervical spinal stenosis patients were fol owed-up for 8 months to 2.3 years. Among them, 14 cases were treated with posterior laminectomy lateral mass fixation, two cases had nerve root palsy in the early stage after implantation, three cases had incomplete paralysis after long-term symptom recurrence and treated with second surgery of scar remove and decompression;15 cases were treated with single-door decompression
laminoplasty, and one case had C 5 never root palsy and shoulder abduction dysfunctionafter treatment, no preoperative symptom recurrence. The nerve root palsy wil restored in 6 weeks for shortest and 9 months for longest. As the limitation of the case number, it is not clear whether there were significant differences in the correlation between C 5 nerve root
palsy and segmental stability, cervical lordosis, spinal decompression degree and the range for spinal cord shift, as wel as the nerve root palsy degree and the cervical spinal stenosis recurrence caused by forward scar between two
treatment methods, so accumulation observation of the cases and clinical experience are needed.

To identify the key elements and available tools of regional health information resources plamling,the study introduced an innovative I-beam map,aiming to solve the two key questions of what and how to plan The paper covered such issues of planning as what is the present situation of regional health information,how to divide functional categories of regional health information resources,what are included in the business subclasses,which core data are used in the business process,which data to share and exchange,how to regulate such data,how to manage the regulations and make continuous improvement,and how to evolve towards planning standardization discriminatively.The study also drew a midfield line with such seven fields as medical service,maternity and child care,disease control and Drevention,health administration,emergency management,blood management and primary healtheare.This midfield line is used,along with stakeholders,planning process,information flow and planning output make the four quadrants,describing the whole process in the I-beam form.This practice can provide the methodology ofhow to plan,in the hope of guiding regional health information resource planning from theory to practice.

Regional health planning is a leading and scientific management philosophy for healthcare development in the international community.Information resources planning paves the way for scientific development.In the ongoing health reform in China,planning of regional health resources will play a key role by leveraging information technology.From the viewpoints of health information resources and information resources planning,the paper defines the concept of regional health information resources planning in microcosmic perspective.It summarized the five features of public welfare,specificity,imbalance,small channel and low noise,and non-symmetry.Authors compared the five planning modes,namely the community medical information resources mode,the general hospitals as the center of information resource mode,the regional PACS mode,the regional health data resource mode,and the regional medical coordination resources mode.In the paper,the planning is rounded up as four key points,that is,the basic steps of situation assessment and analysis,routine work of health information standardization,the planning should both comply with general rules of information resource planning and characteristics of the health sector,in addition to guidelines of forward-looking concepts.

Objective To observe how exogenous estrogen influences the distribution and the expression of NOS positive neurons in the supraoptic nuclei of hypothalamus in the overiectomized female rats. Methods The 2-3-month-old female rats(n=40) were selected as the healthy and nulli-copulatory experimental animals. Rats were divided into following groups: normal control group(n=10), ovariectomized control group(n=10), and two experimental groups that have been injected with estrogen for post-operative 40 days(n=10) and for post-operative 70 days(n=10). Finally, all the animals were infused and the brains were removed. Immunohistochemical (SABC) method was adopted to count the number of NOS poitive neurons and observed the NOS poitive neuronal morphology under the light microscope. The image analysis system was used to test the average gray value of immunoreactivity in NOS positive neurons. Results In the ovariectomized control group, the density of NOS positive neurons in supraoptic nucleus was significantly increased and their shapes were bigger than that of the normal control group(P<0.05). The density and the form of the NOS positive neurons in supraoptic nucleons had no apparent difference between the estrogen for post-operative 40 days group and the ovariectomizeed control group(P>0.05).In the group after estrogen-injection 2 months compared with the normal control group, and the ovariectomized control group, both of the NOS positive neurons' density and the size become significantly decreased, and the staining of cells was lesser in the group injected with estrogen for post-operation 70 days. Conclusion The present results suggest that exogenous estrogen may influence the distribution and the expression of NOS positive neurons in supraoptic nucleus of hypothalamus of ovariectomized female rats.

[Objective] To study the correlation between kidney cell DNA degradation and postmortem interval within the span of 6-48 hour after the subject rats′ death.[Methods] To select 18 healthy mature female SD rats and equally divide them into 6 groups.To execute the rats with cervical spine articulation and put the rats under the incubator temperature of 25.1℃ (the average temperature of the 5 previous Decembers in Guangzhou prefecture).Sample kidney tissue from the rat separately 0 hour,6 hours,12 hours,24 hours,36 hours,48 hours,and 60 hours after the rats′ execution to prepare monoplast suspension,which is committed to comet assay.The comet images were captured by fluorescence CCD.Kinetic Comet 4.0 software was used to analyze images.Relevant data were collected by kinetic Comet 4.0 software and were subjected to Kruskal-Wallis test.[Results] Within the postmortem interval of 6-48 h,the number of SD rat kidney cell DNA fragments increased as the postmortem interval lengthens.So did the comet tail length.The Oliver tail moment and tail DNA of comet also showed sign of increase in positive proportion to the postmortem interval (their values corresponding to 60-hour-postmortem-interval were not obtainable.Kruskal-Wallis test indicated:the discrepancies of TL among the 6 groups were all significant (P ＜ 0.01).The difference of TM between 6 h group and 12 h group was not significant (P ＞ 0.05).The difference of TM between 24 h and 36 h was significant (P ＜ 0.05).The difference of TDNA among 6 h,12 h,and 36 h groups were not significant (P ＞ 0.05).The difference of TDNA between 36 h and 48 h was significant (P ＜ 0.05).[Conclusion] Degradation of nuclear DNA of the rat kidney cells increases as the postmortem interval lengthens and comet assay may provide important empirical evidence for determining the postmortem interval.

Objective To explore the value of preoperative spleen-liver volume ratio (SLVR) for predicting recurrence of primary liver cancer after hepatectomy.Methods Clinical data of 86 cases of hepatocellular carcinoma undergoing hepatectomy were analyzed retrospectively from January 2009 to December 2014.According to the preoperative SLVR,these patients were divided into two groups:SLVR ＜ 0.8 group (low SLVR group) and SLVR≥0.8 group (high SLVR group).Patients were followed-up until June 2015.Cox ratio risk pattern analysis was used for the recurrent correlative factors.Results The 1-,3-,and 5-year survival rates were 95.5％,88.6％,and 81.8％ in the low SLVR group,and 73.8％,47.6％,and 40.5％ in the high SLVR group,respectively.The difference were statistically significant between two groups (P ＜0.05).Cox regression analysis revealed that SLVR≥0.8,AFP-L3％ ≥10％,the maximum diameter of the tumor ＞ 5 cm,and hepatic or portal vein tumor thrombus were independent predictors of poor disease-free survival after hepatectomy for hepatocellular carcinomas (P ＜ 0.05).Conclusions Preoperative SLVR≥0.8 is an independent adverse predictor of poor disease-free survival.
