Objective To investigate the loss of heterozygosity (LOH) of 3p D3S1300 and D3S1289 loci of plasma DNA of lung cancer (LC) patients and evaluate its value for a tumor marker of lung cancer.Methods Two microsatellite markers,D3S1300 and D3S1289,were analyzed by PCR and silver staining to investigate LOH of the plasma DNA and cancer tissue DNA from 69 cases of primary lung cancer,and the plasma DNA from 40 control subjects.Results The percentages of D3S1300 LOH detected in the tumor tissue and plasma DNA of LC patients were 40.6% and 29.0% respectively,while the percentages of D3S1289 LOH were 31.9% and 24.6% respectively.In contrast,only 2 cases of D3S1300 LOH and 3 cases of D3S1289 LOH were found in plasma DNA of control group (P

ObjectiveTo investigate the dynamic change of cerebral aquaporin 4 (AQP4) expression level during traumatic brain injury (TBI) in rats and the relationship between AQP4 expression and traumatic brain injury and edema. MethodsThe experimental TBI model was established by bumpiness of free falling body according to Feeney's. The changes of brain water content (BWC) and permeability of blood-brain barrier (BBB) were measured by the methods of wet and dry weight and Evans blue fluorometry. Immunohistochemistry was used to determine the change of expression of AQP4 during different periods after TBI. Results6 h after TBI, water content of brain tissue and EB content in the contusion side significantly increased, and the protein expression of AQP4 in contusion marginal region began to increase. They reached summit 24 h after operation and did not come back normal level 5 d after operation. There was significantly positive correlation between protein expression of AQP4 and change of EB content (r=0.957486,P<0.05). ConclusionThe dynamic change of cerebral AQP4 expression level closely related to the destruction of BBB and the formation of cerebral edema during traumatic brain injury.

Functional magnetic resonance imaging (fMRI) is an imaging method of function brain area by stimulate in magnetic resonance facility; it can exactitude reflect the nerve activity level of brain and confirm the function brain area in alive body; it is a new impersonality imagine method to evaluate the cognitive function of human. Cognitive function obstacle is a clinical syndrome of damaging cognitive function by manifold reasons and can be leaded by many diseases in clinic. Studying changed function brain area by fMRI can offer an impersonality and intuition imagine evidence to forepart prevent, diagnose and therapy of the diseases of cognitive function obstacle.

ObjectiveTo observe the protective effects of Chinese medicine Naoshuning on neurological deficits following traumatic brain injury (TBI) in rats.MethodsCerebral contusion was produced by dropping weight,the beam-walking task was employed to observe neurological functional changes,water content in the brain tissue and neuropathological changes were also evaluated.ResultsWithin one week the ability to process in beam-walking task was significantly lessened,the outcome of beam-walking task of Naoshuning group was significantly better than that of the model group.Water content in the brain tissue and neuropathological changes were also alleviated in Naoshuning group compared with that in model group.ConclusionEarly alleviating brain edema,protecting brain tissue may be one of the mechanism of Chinese medicine to ameliorate the behavior deficits following TBI in rats.

ObjectiveTo investigate the characteristics of personality in patients with depression. Methods24 patients with depression and 24 normal controls were measured with Minnesota Multiphasic Personality Inventory (MMPI) software. ResultsCompared with the control, patient with depression showed significantly difference in neuroticism, extraversionn-introversion, anxiety, repression, manifest anxiety scale, ego strength, dependency, dominance (P<0.05). the T score of N and repression is higher than the Chinese usual score. ConclusionThe depression patients show their personality as repression, inferiority, melancholy, anxiety, bad tolerance, overstrung and dependent.

[Objective] To discuss the mechanism and relative problems of lumbar traction. [Method] Relevant articles and retrospect clinical data in the author's hospital were reviewed. Review relevant articles and retrospect clinical data of our hospital. [ Result ] Traction force : 40 kg + 15% ～ 20% of body weight, fineness rate reached 83.5% in 1606 patients being treated. According to course of disease, fineness rate was 90. 1% in the group of less than 3 years, 68.2% in the group of more than 3 years. [ Conclusion] Lumbosacral nerve root leave the peak of the protruding nucleus and establish a new harmonious "root-disc" relationship after traction. The pressure and tension to the nerve root reduces or disappears, meanwhile, the pain of low back and leg is alleviated or eradicated. Appropriate traction weight and correct traction body posture are key factors of good therapeutic effect.

OBJECTIVE To provide evidence to establish properly protocol for medical cosmetic institutions.METHODS Through investigation to analyze the current situation and problems of disinfection and isolation in the medical cosmetic institutions.RESULTS There were 86.7% medical cosmetic institutions located in commercial buildings.And there were 33.3% institutions with improper layout of therapeutic room,sterilizing room and dressing room resulting from insufficient space or less rooms.The illumination intensity of the ultraviolet lamp and the disinfection effect of air were not coincident with standards.CONCLUSIONS There are many problems of disinfection and isolation in the medical cosmetic institutions,the disinfection is insufficient,the ultraviolet light is in wild-using,people only focus on using,but ignore irradiation dose and distance.It is very important for strictly observing Hospital Infection Management Methods,Disinfection Technology Standards and Disinfection Management Methods,and strengthening the management of disinfection and isolation in the medical cosmetic institutions.

Objective To explore the medication closed-loop management of huangshi central hospital based on electronic medical records.Methods Diversified pharmaceutical information platform was constructed.The full coverage of all aspects of medication information,such as ordering/prescribing,transcribing,distributing,preparing,dispensing,administering,documenting,and monitoring was realized.Results The medication management and use had no information gap,and bias could be controlled to form a closed-loop management.Conclusion Application of the new information technology in the field of pharmaceutical care can improve work efficiency,reduce medication errors,broaden the vision of clinical pharmacists and scope of work,and improve the overall level of pharmaceutical care.

Electroencephalogram non-linear analysis is one of the methods to study brain electric signal complexity and the mutual connection of signals based on the non-linearity principle and method. It can provide condition such as the neural networks function, contact information, the changing trajectory cerebrum function activity. It can be used for nerve spirit disease studying, the depth anaesthetize monitor ,the sleep studies in modern medicine, it breaks the ice in traditional Chinese medicine just now. The application of electroencephalogram non-linear analysis has open up an exhibition further to cerebrum's research.

Objective To explore the characteristics of patients with stagnation of liver-qi syndrome using brain functional imaging techniques.Methods10 patients with stagnation of liver-qi syndrome and 20 normal persons whom paired by sex and age were scanned with positron emission tomography(PET).Data analysis was carried out using SPM in MATLAB software.ResultsCompared with normal,some cerebral areas of the patients with stagnation of liver-qi syndrome showed glucose metabolism letdown(P<0.001),including right parietal lobe(postcentral gyrus,BA1/2),temporal lobe(middle temporal gyrus,BA37),frontal lobe(middle frontal gyrus,BA9/10)etc.,while some cerebral areas showed glucose metabolism heighten(P<0.001)including right frontal lobe(superior frontal gyrus,inferior fontal gyrus,BA22/28/44),right cingulated gyrus,double midbrain and cerebella,etc.ConclusionThe function of some cerebral areas can be changed undergoing stagnation of liver-qi syndrome.
