AlM:To observe the clinical effect of 2. 2mm micro-incision phacoemulsification ( Phaco ) combined intraocular lens( lOL) implantation in the eyes with short axial length and compared with traditional 3. 0mm incision phacoemulsification operation for clinical work and research objective information.METHODS:ln this prospective clinical control study, 60 cases (60 eyes) with cataract performed 2. 2mm micro-incision phacoemulsification combined lOL implantation ( micro-incision group, implanted Akreos Ml60 lOL ) and 3. 0mm incision phacoemulsification operation ( small incision group, implanted Akreos Adapt lOL ) , whose axial length ranged 17. 68 ~ 21. 32mm, average 20. 35 ± 0. 61mm. Average axiall ength respectively of two groups:20.57±0.39mm and 20.21±0.52mm. Effect Phaco time ( EPT ) and average ultrasonic energy ( AVE ) were recorded. The best corrected visual acuity ( BCVA ) , intraocular pressure ( lOP ) , anterior chamber depth ( ACD) , corneal endothelial cell density and the operative complications were observed postoperatively. All cases were followed up at 1, 7, 30 and 90d after operation.RESULTS:EPT and AVE between two groups had no statistical significance(P>0. 05). At the 1, 7 and 30d after surgery, induced astigmatism ( SlA ) of micro-incision group was lower than that of small-incision group. SlA between two groups had statistically significant ( P <0. 05), but in the 90d SlA between two groups had no statistical significance(P>0. 05). At the 7d, the BCVA between two groups had statistical significance(P<0. 05), but at the 30 and 90d, BCVA between two groups had no statistical significance(P>0. 05). At the 7, 30 and 90d, corneal endothelial cell density of micro-incision group was higher than that of small incision group. Corneal endothelial cell density between two groups had no statistical significance. The mean ACD was significant increased postoperatively than preoperatively and had no statistical significance ( P>0. 05 ) . The anterior chamber stabilized during the operation. There was not incision hot harmed during operation and postoperation.CONCLUSlON:Compared with 2. 2mm micro-incision and traditional 3. 0mm incision phacoemulsification, two groups have the same safety and 2. 2mm micro-incision phacoemulsification has small SlA, organization small harm and improved visual acuity in early stage.

Objective To evaluate prognostic value of electroencephalogram (EEG) in neonatal with hypoxic ischemic encephalopathy (HIE). Methods Sixty two infants with HIE was studied by doing physical examination, intelligence test, CT and EEG. Their clinical outcome was compared to their EEG in the first month after birth. Results Incidence of sequelae in normal or mild abnormal EEG and severe abnormal EEG were 3%, 29%, respectively. Among three infants of EEG cases, two dead and one developed cerebral palsy infant. Among four of burst suppression found in the EEGs, two cases dead, one developed cerebral palsy, one was normal. In five of hypoactive EEG, one dead, one developed cerebral palsy, and the other was with low IQ. Conlusion The prognosis is related to the background activity of EEG. The presence of a burst suppression EEG pattern and a hypoactive/flat EEG are negative prognostic criteria.

Xuan Fei Run Zao Decoction was used for treatment of 486 cases of psoriasis with a total effective rate of 90. 3%, so as to test and verify the TCM theory of the lung being in charge of the hair and the lung being closely related with derma tosis. Clinical study found that in patients of psoriasis there was humoral immunological hyperfunction, manifesting increases of IgG and IgA; trace elements copper and ferrum levels increased and zinc, manganese and calcium decreased In the hair: packed cell volume and viscosity of whole blood increased, and erythrocyte sedimentation rate increased. It is suggested that psoriasis is possibly related to changes of immunity, blood rheology and trace elements in the body.

OBJECTIVE To determine the distribution of pathogens of bacterial infection in respiratory intensive care unit (RICU) to provide reference for the prevention of hospital infection. METHODS To collect specimens of the patients received endotracheal intubation from Jan 2006 to Dec 2006 in our RICU,to identify pathogens and drug sensitivity test. RESULTS We isolated 105 pathogenic bacteria from 626 specimens of the 58 patients,the G-bacilli accounted for 64.76%,G+ cocci accounted for 20.95%,fungi accounted for 12.38%; Acinetobacter baumannii was one of the main G-bacilli accounted for 19.05%. Staphylococcus aureus of G+ cocci for 9.52%,and Candida albicans of fungi for 7.62%; from 105 pathogens,65 from the respiratory tract,15 from the for urinary tract,eight from a catheter tube,six from the digestive tract,five from the blood,four from the various drainage tubes and two from the incision secretions. CONCLUSIONS Hospital infection pathogens exist in the respiratory tract infection in hospitalized patients of respiratory ICU with risk factors of age,underlying diseases,time in the intensive care unit,ventilator time and the use of invasive procedures in a certain relationship.

From the TCM theoretical basis and the evidences of acupoint selection and acupuncture and moxibustion methods regarding acupuncture for post-traumatic stress disorder (PTSD), a theoretical discussion is made in this article, also a review regarding the key mechanism of experiment researches on acupuncture for PTSD is made from aspects of neurobiology and brain functional imaging, etc., which could further clarify the effect mechanism of acupuncture on PTSD. It is found that PTSD is a kind of stress syndrome accompanied with a variety of abnormal mental symptom , and acupuncture has superior effect on PTSD. Based on these, the research progress and deficiency on current mechanism study of PTSD are reviewed, hoping to offer ideas for upcoming research and to serve the clinical practice better.

Objective To compare the effects of propofol and ketamine on long-term memory and the expression of brain N-methylgroup-D-aspartate receptor 2B(NMDAR2B) and Gamma-aminobutyric acid receptor 1(GABAR1) in aged rats, and preliminary investigate the relation between the long-term memory and expression of neurotransmitter receptors in different cerebral areas. Methods The aged male rats were randomly divided into control group,propofol group and ketamine group. Morris water maze training was performed in all the rats of three groups for 5 days. On the 6th day, intraperitoneal injection of 50 mg?mL-1 propofol was administrated in propofol group,80 mg?mL-1 ketamine was intraperitoneally injected in ketamine group,and blank control group was given the same dose of saline.Seven days after the administration,space exploration experiment and navigation experiment test were performed to test the impact on the learning and memory ability of rats. After that, the expression levels of GABAR1 and NMDAR2B in temporal lobe and hippocampal CA1 region of the rat brain were detected by immunofluorescence and FISH technique. Results The results of Morris water maze showed there was no significant difference between propofol group (9.49±1.24) s and blank control group (8.82±2.22) s.There was statistically significant difference between ketamine group (12.04±2.67) s and blank control group (P<0.05),with longer latency time and less number of times of passing through target as compared with blank control group.By using immunohistochemistry and FISH technique,the expression of GABAR1 in temporal lobe and hippocampal CA1 region of the rat brain was not significantly different between propofol group and blank control group,but it was significantly up-regulated in ketamine group as compared with blank control group ( P<0.05) . The expression of NMDAR2B in temporal lobe and hippocampal CA1 region of the rat brain was not significantly different between propofol group and blank control group,but it was significantly down-regulated in ketamine group as compared with blank control group (P<0.05). Conclusion Propofol anesthesia alone had no effect on long-term learning and memory,but ketamine anesthesia can result in long-term learning and memory impairment. The mechanism may be related with down-regulation of the expression of NMDAR2B receptor and up-regulation of GABAR1 not only in CA1 region hippocampus,but also in temporal lobe.

Objective To observe the change of learning and memory quality and the expression change of GABAR1 and NMDAR2B in aged SD rat cerebral temporal lobe by propofol injection and discuss the influence that may be caused by propofol.Methods Aged male sd rats were randomly divided into three groups,each group of 20.Propofol intraperitoneal injection was implemented to groups P1 and P7 according 50 mg/kg and maintained anesthesia for 3 hours.The same dose of emulsion was given to control group. Morris water maze test was done in the first days and the seventh days after intraperitoneal injection.Then the left temporal lobe was gathered and the mRNA transcription and protein expression of GABAR1 and NMDAR2B were detected by FISH and Immunofluorescence technique.Results Compared with control group,the latent time of group P1 was significantly prolonged and the numbers of passing through the target frequency were decreased significantly (P <0.05).Group P7 had no significant differences.The mRNA transcription and protein expression of GABAR1 in group P1 were increased significantly and the mRNA transcription and protein expression of NMDAR2B in group P1 were decreased significantly (P <0.05 ). Group P7 had no significant differences.Conclusion The short-term memory of brain declined after propofol was used.This may be related to the function of temporal lobe.The mechanism may be related to the up regulation of GABAR1 and the down regulation of NMDAR2B simultaneously.
