Parkinson's disease (PD) is a common neurodegenerative disorder with typical motor symptoms and a variety of non-motor symptoms,including neuropsychiatric symptoms,autonomic dysfunctions,abnormal sense,sleep disorders and fatigue.Studies showed that several non-motor symptoms,such as olfactory dysfunction,constipation,rapid eye movement sleep behavior disorder,depression and fatigue,can occur before the onset of motor symptoms.Fatigue has been considered as one of the most disabling symptoms,and it has a significant impact on activity of daily living and quality of life,and brings heavy burdens to caregivers.However,fatigue in PD has no special biomarkers,so clinicians are lack of the recognition and intervention.Here,we will expound the prevalence,risk factors,rating scales and potential mechanism relating to neuropathology,neuroinflammation and neurobiochemistry in PD patients with fatigue.

Aim Toinvestigatetheroleofhyperglyce-mia in cerebral ischemia/reperfusion(I/R)injury with a middle cerebral artery occlusion(MCAO)rat model anditsmechanism.Methods EightyhealthymaleSD rats were randomly assigned into sham group, I/R group (normoglycemia),hyperglycemic I/R groupⅠ(HG1 )and hyperglycemic I/R groupⅡ(HG2 ).The cerebral I/R model was established by occluding the middle cerebral artery(MCA)in rats.Hyperglycemia was induced by intraperitoneal injection of 50% glu-cose solution.Neurological deficit was determined by Ludmila Belayev test;infarct size and brain edema were measured by TTC staining;mitophagy was ob-served by double immunofluorescent staining and elec-tron microscope.The expressions of autophagy-related proteins(LC3 and Beclin-1 )and apoptosis-related pro-teins(Cyt-C,AIF,caspase-9 and caspase-3 )were ex-aminedbyWesternblotfurtherly.Results Bloodglu-cose level was controlled at 4 mmol·L-1 (normoglyce-mia),10 mmol · L-1 (HG1 ) and 20 mmol · L-1 (HG2)respectively.There were no significant differ-ences between model group and HG1 group in neuro-logical deficit scores,infarct volume and edema size(P>0. 05 ).However,these indications in HG2 group were significantly increased compared with model group (P<0. 05 ).After 3 days of reperfusion,the level of mitophagy was significantly reduced accompanied with increased mitochondria damages in HG 2 group (P <0. 05 ),and the expressions of mitochondrial related ap-optotic proteins(Cyt-C,AIF,caspase-9 and caspase-3 ) were significantly increased accordingly compared to modelgroup.Conclusions Mildhyperglycemiacan not intensify the cerebal ischemic injury.In contrast, severe hyperglycemia significantly aggravates the brain ischemic injury by inhibiting the removal of injured mi-tochondria in a manner of mitophagy,thus amplifying the mitochondrial mediated cascade damage responses.

Current resource of medical morality is in shortage.When emphasizing the exterior supervision of the government,we should put more emphasis on the exterior restricting factors which are more profound,such as the excursion of the norm to the experts,the excessive market-orientation of medical innovation,the shortage of financial devotion,the deficiency of hospital management system.To solve the above problems,a fair medical surrounding is to be built,a patients association be established,and the social honesty and credit mechanism be rebuilt.

Abstract?AlM:To analyze the blindness causes of 1854 cases in our hospital hospitalized patients, and explore the strategy and direction of blindness prevention according to the different treatment efficacy.?METHODS: Cluster sampling was used to select from September 2010 to August 2013 in our hospital department of ophthalmology patients 5 473 cases, in which total of 1 854 cases of blind patients, accounting for 33. 88% of hospitalized patients. According to the WHO's criteria of blindness. The BCVA enacted <0. 05 or vision radius less than 10 degrees are for the blind, and the exclusion of less than 3 years old children don't cope with visual inspection of the inclusion criteria for age and cause of blindness blind patients were analyzed. To the blind to patient age and etiology were analyzed, the main cause of blindness and statistics of all ages, records of the blind patients after treatment eye sight;and calculating the blindness of the literacy rate, on the blindness through analysis of the causes of the risk treatment.?RESULTS:ln 1 854 cases of blind patients, including 728 people right-eye blinding, 767 people left-eyes blinding, 359 people total blinding, adding up to 2 213 eyes, aged from 60~80 years old were in the majority. The top three diseases resulting blindness were cataract, diabetic retinopathy and glaucoma. ln 2 213 blind eyes, the eyes treated were 2 172, of which 1 762 eyes ( 81. 12%) were succeeded, 410 eyes ( 18. 88%) failed. ln the failed cases, the first three diseases were diabetic retinopathy, glaucoma and retinal detachment.?CONCLUSlON: ln recent years, disease etiology of blinding eye has changed, but cataracts, diabetic retinopathy and glaucoma are still high incidence of blindness due, so the treatment of diabetic retinopathy, glaucoma and retinal detachment should be the emphasis for blindness prevention and treatment in the future.

Objective To investigate the effect and safety of proximal femur locking compression plate for treatment of intertrochanteric fracture in old patients. Methods Clinical data and visit records of 98 cases of intertrochanteric fracture old patients were analysed retro-spectively. According to the treatment of operative methods, these patients were divided into two groups: 46 patients in the control group were given the dynamic hip screw fixation; the other 52 cases in the observation group were given the proximal femur locking compression plate . Compared the therapeutic effect and safety of the two groups. Results The short-term and long-term therapeutic effect of observation group were significantly better than the control group,and the safety of observation group was higher than that of the control group,the differ-ences were statistically significant (P<0. 05). Conclusion Proximal femur locking compression plates is an effective surgical treatment for old patients with intertrochanteric fracture. It can significantly improve the function of hip joint and reduce the risk of postoperative complica-tions. As it is of significant effect and high safety, it is worthy of clinical popularization.

BACKGROUND:Al ogeneic penetrating keratoplasty is the most effective method for treating corneal blindness. However, the incidence of rejections is high after keratoplasty, so it is urgent to develop an immunosuppressive drug with high efficacy and low toxicity. OBJECTIVE:To establish al ogeneic penetrating keratoplasty models and monitor the expression of tumor necrosis factor-αin blank control group and after transforming growth factor-β1 eyedrop during acute rejection period of corneal grafts. METHODS:Al ogeneic penetrating keratoplasty models were established and were randomly divided into blank control group, ciclosporin A group (1%ciclosporin A), and transforming growth factor-β1 group (1μg/ml transforming growth factor-β1 eyedrop). The medications from each group commenced at 1 day after surgery, one eyedrop once, three eyedrops per day. Al the operated eyes were given 0.3%ofloxacin ophthalmic solutions and 0.5%tropicaide ophthalmic solution, three times per day, for 12 days. The corneal grafts were harvested for hematoxylin-eosin staining and immunihistochemical staining (SABC method), to detect tumor necrosis factor-αexpression in corneal grafts. RESULTS AND CONCLUSION:Hematoxylin-eosin staining showed that, corneal grafts were significantly thickened, a large number of histoleucocytes and lymphocytes infiltrated in the blank control group;corneal grafts showed normal thickness and no inflammatory cel s infiltrated in the transforming growth factor-β1 group. Immunohistochemical staining showed that, there were less cel s positive for tumor necrosis factor-αin the transforming growth factor-β1 group compared with the blank control group (P<0.05). Transforming growth factor-β1 eyedrops can reduce the expression of tumor necrosis factor-αin the corneal grafts during acute rejection period, and reduce the inflammatory cel s infiltration in the corneal grafts, which is probably the mechanism of transforming growth factor-β1 to prevent and treat corneal al ograft rejection.

There were 12 patients who were all type C1 or C3 epipod comminuted fracture.By means of the internal fixation,all patients were transplanted with the nanometer artificial bones,comprising hydroxyapatite and ?-tricalcium phosphate.The 12 patients used the bacteriophages preoperation,during operation and 3 days postoperation.They were free from pressure dressing and started to take exercises 48 hours postoperatively.Followed up for 6-12 months,all of the 12 patients healed well.So nanometer artificial bone is an effective method for the epipodite comminuted fracture,without any severe toxicity or complications.

Objective To verify the variation of mitogen-activated protein kinase kinase kinase 5 (MAPKKK5) gene expression in patients with cryptogenic refractory temporal lobe epilepsy (TLE) and to evaluate the possible molecular pathogenesis of intractable TLE. Methods Reverse transcription polymerase chain reaction (RT-PCR) and Western-blot analysis were used to measure the expression alterations of MAPKKK5 mRNA as well as its protein product MAPKKK5 in temporal cortex samples from patients who had undergone temporal lobectomy for intractable epilepsy (n=10). Tissues from 10 subjects who did not have epilepsy served as controls. Results The expression of MAPKKK5 mRNA (1.001?0.321) and its protein MAPKKK5 (0.359?0.299) were significantly increased in epileptic brain compared with the controls (0.648?0.157, 0.137?0.084, respectively) (all P
