AlM:To compare the clinical results of different surgical methods for diabetic antipathy.
METHODS: Eighty cases ( 102 eyes ) with diabetic antipathy were selected in our hospital from January 2012 to December 2013. Thirty-eight cases (48 eyes) in group A received joint surgical treatment, 42 cases (54 eyes) in group B took staging of surgical treatment. The clinical effect was observed in both groups.
RESULTS: The vision after surgery was improved than that of before surgery in two groups, there were no significant differences ( P > 0. 05 ). A postoperative complication rate was 16. 7% in group A and 22. 2% in group B, showed no significant difference (P>0. 05).
CONCLUSlON: Surgery and staging joint surgery are both feasible for diabetic retinopathy patients, can, improve the visionr. Both of them are worthy of clinical application.

BACKGROUND: Cerebral infarction is commonly associated with blood stasis syndrome. Abnormal alternation of blood rheology is generally manifested as increased blood viscosity and hematocrit (HCT). In isometric hemodilution, a certain amount of red blood cell (RBC) is shifted by bleeding and simultaneously, isometric diluter is supplemented to reduce whole blood viscosity.OBJECTIVE: To observe the improvement of astragalus injection, the Chinese herb for qi tonification and isometric hemodilution on blood rheology in blood stasis syndrome of cerebral infarction.DESIGN: Randomized controlled experiment and case-control analysis were designed.SETTING: Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology. PARTICIPANTS: In cerebral infarction group (infarction group), 64 inpatients of senile ischemic cerebral vascular disease were collected from Union Hospital Affiliated to Huazhong University of Science and Technology from March 2002 to March 2004. Al l of cases were aged over 60 years and were in conformity with the diagnostic criteria on blood stasis syndrome. According to random number table, routine treatment group (routine group) and the group of integrative therapy of Chinese and western medicine (experimental group) were divided, 32 cases in each one. 47 healthy people of similar age and diagnosed with routine physical examination were selected in normal control. METHODS: In routine group, cerebral infarction was treated with routine therapy, including extending capacity, reducing viscosity, resisting coagulation, blocking aggregation of platelet and dehydration and general symp tomatic supporting treatment. In experimental group, on basis of routine treatment, isometric hemodilution and astragalus injection, the Chinese herb for qi tonification were used. 10% of total blood amount (about 450-650 mL) was collected from vein, and colloid solution of same volume was injected intravenously. The treatment was applied once every 5 days, continuously for 3 times. Astragalus injection 50 mL mixed with physical saline 250 mL was intravenous dropped, once per day, continuously for 3 weeks. MAIN OUTCOME MEASURES: ① Comparison of indexes in bloodrheology before and after treatment in routine group and experimental group. ② Comparison of indexes in blood rheology between normal control and infarction group. RESULTS: According to intention management, 64 patients and 47 normal persons all entered result analysis. ① Comparison between infarction group and normal control: RVB, HCT and PFC (fibrinogen) were higher than normal control [(3.90±0.73), (3.40±0.28) mPa·s; (46.39±6.03) %,(42.61±2.91)%; (3.25±0.75), (3.08±0.46) g/L, P < 0.01, 0.05], MTIE (de formity index of RBC) was lower than normal control (0.958±0.006, 0.961 Shen H,Lu YD.Study on quantitative messurement of immunohistochemical ±0.004, P < 0.05). ② Comparison between routine group and experimental group: Difference in some indexes presented before the treatment. After treatment, RVB, HCT and PFC in experimental grou p were all lower than routine group [(3.90±0.52), (4.21±0.68) mPa·s; (43.80±3.29)%, (48.47±4.50)%; (3.31±0.60), (3.68±0.67) g/L, P < 0.01, 0.05]. CONCLUSION: Isometric hemodilution therapy and astragalus injection reduces blood viscosity, improves blood rheology and alleviates clinical svmptoms of blood stasis syndrome in senile cerebral infarction.

Objective To investigate the axonal lesion in chronic inflammatory demyelinating polyneuropathy(CIDP).Methods Eighteen patients had undergone sural nerve biopsy.The clinical and electrophysiological distinction based on the different pathological changes were analyzed.Results Five patients with demyelination predominance which presented myelinated fiber with thin myelin.Three of them showed also mild axonal degeneration.Eight patients with axonal lesion predominance which presented Wallerian degeneration and regeneration of myelinated fibers.Three patients with mixed myelin and axon lesion of myelinated fibers and two with mild lesion.There was no significant difference between CIDP predominantly with axonal lesion and demyelination.Electrophysiological examination shows both axonal lesion and demyelination feature in some of the 2 types patients at the same time.Conclusions Axonal lesion is a common pathological change in CIDP and should not be considered as an exclusive criterion in diagnosis of the disease.Infiltration of macrophages is a common change.

To summarize the clinical characters of optic neuritis caused by antituberculosis drugs, and to discuss the prevention countermeasures.
● METHODS: The clinical characters of optic neuritis caused by antituberculosis drugs among those outpatients and ward patients from January 2003 to January 2013 were reviewed and analyzed.
● RESULTS: Optic neuritis caused by antituberculosis drugs was rare ( 17 / 60000 ), while retrobulbar neuritis was common. The drugs inducing optical neuritis were mainly ethambutol, followed by isoniazid and streptomycin. The vision of patients would have different degrees of improvement via the following treatment after specific diagnosis, i. e. , timely stopping the tuberculosis medicine associated with optic neuritis, and taking vitamin supplements, dilating blood vessels and applying hormone therapy according to the illness.
●CONCLUSlON: We should pay attention to the change of the vision of patients during the usage of antituberculosis drugs. ln the case of sudden eyesight deterioration, ophthalmology examination and timely treatment are advised preventing blindness.

Objective To investigate the real-time regulatory effects of IFN-γ, programed death ligand 2(PDL2) and janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling pathway on the adherence, proliferation and migration of human placenta-derived mesenchymal stem cells(hPMSCs) based on a finding that IFN-γ could enhance the expression of PDL2 in hPMSCs through JAK/STAT signaling pathway.Methods hPMSCs were isolated by using enzyme digestion method and then co-cultured with IFN-γ, anti-PDL2 monoclonal antibody (anti-PDL2 McAb) and JAK inhibitor, respectively.Real-time cell analysis (RTCA) was used to detect the dynamic changes in the adherence, proliferation and migration of hPMSCs following various interventions.Results IFN-γ remarkably suppressed hPMSCs proliferation during the period from 40 hours to 80 hours after intervention and also inhibited the non-targeted migration of hPMSCs.However, hPMSCs adherence was not affected by IFN-γ.Co-culturing hPMSCs with anti-PDL2 McAb significantly enhanced hPMSCs adhesion and inhibited their non-targeted migration, but had no significant effect on hPMSCs proliferation.Furthermore, the proliferation of hPMSCs co-cultured with IFN-γ and anti-PDL2 McAb was significantly inhibited as compared with that of anti-PDL2McAb treatment group.The adhesion, migration and proliferation of hPMSCs were significantly inhibited after co-culturing them with JAK inhibitor.Conclusion IFN-γ can remarkably suppress the proliferation and migration of hPMSCs.PDL2 can enhance the migration and inhibit the adhesion of hPMSCs.JAK/STAT signaling pathway is involved in regulating the adhesion, migration and proliferation of hPMSCs.

OBJECTIVE:To investigate the improving effect of phenylethanoid glycosides (PhGCs) from Tibetan medicine Phlomis younghusbandii on rats with acute high-altitude cerebral edema. METHODS:60 Wistar rats were randomly divided into a normoxia control group (isometric sterile water for injection),a hypoxia model group (isometric sterile water for injection),a dexamethasone group(4 mg/kg),and three groups of PhGCs at high(400 mg/kg),middle(200 mg/kg)and low(50 mg/kg)dos-es,with 10 rats in each group. The rats were given drugs,ig,6 d before the establishment of models. On the 4th day of administra-tion,ig,the rats in all groups except the normoxia blank group were placed in a simulated 8 000 m altitude plateau environment for 72 h hypoxic exposure to establish the rat models of high-altitude cerebral edema. Following HE stain,the pathological changes in rats’brain tissues were observed under the light microscope. Dry-wet proportion method was used to determine the water con-tents in rats’brain. The content of MDA and the activities of SOD and GSH in rats’brain tissues were detected. Enzyme-linked im-munosorbent assay was adopted to determine the contents of IL-1β and TNF-α in rats’serum and brain tissues. RESULTS:Com-pared to the rats in the normoxia control group,those in the hypoxia model group showed obvious brain edema,and thickened lacu-nas around cells and vessels and inflammatory cell infiltration, higher water contents and MDA and weaker activities of SOD and GSH in brain,and higher contents of IL-1β and TNF-α in serum and brain tissues. There were statistically significances (P<0.01 or P<0.05). Compared to the rats in the hypoxia model group,those in the groups of PhGCs at high,middleand low dosages demonstrated less inflammatory cell infiltration and lower water contents in brain tissues,in which the groups of PhGCs at high and middle dosages demonstrated lower content of MDA and stronger activities of SOD and GSH in brain tissues, and lower contents of IL-1β and TNF-α in serum and brain tissues. There were statistically significances (P<0.01 or P<0.05). CONCLUSIONS:PhGCs can obviously alleviate the acute cerebral injury in rats which is caused by acute hypoxia and has im-provement effect to some degree on the rats with acute high-altitude cerebral edema.

The blood reserve bank for preparedness against war,as a store of blood products and a base of blood supply,bears the responsibility of wartime emergency blood supply.Site selection is the basis of the construction of the blood reserve bank and directly related with its capacity of blood supply in both peace and wartime.The decision-making process concerning site selection is complicated and multi-aimed with various factors mutually related and conditioned.This paper proposes some basic principles of selecting the site of the blood reserve bank for preparedness against war,which are hoped to be beneficial for the demonstration of its site selection.

Objective To analyze the clinical features of patients with cholelithiasis treated in our hospital in the recent 10 years to explore the changing tendency of the spectrum of cholelithiasis in the Jiaodong region. Methods The clinical data of 2899 patients receiving operation for cholelithiasis in this hospital between January 1998 and January 2008 were retrospectively analyzed. The clinical parameters of sex, age and the lesion sites were reviewed. Compared with the clinical data of cholelithiasis patients in 1991, the data of the 2899 patients were statistically analyzed by SPSS 12.0 package.Results Significant differences existed in sex, e peak morbidity, and lesion sites. The ratio of male patients and female patients with cholelithiasis in differents site had obvious diversity. The constituent ratio of the female was manifestly higher than that of the male. The peak morbidity age range of cholecystolithiasis was 40 to 69. The peak age of gallbladder stones combined with common bile duct stones was 70 to 79, which was the same as that of common bile duct stones. The peak age of intrahepatic bile duct stones was 40 to 59. The constituent ratio of cholecystolithiasis was obviously higher than cholelithiasis in other sites. The incidence of cholecystolithiasis increased with age. Conclusion In the recent 10 years, female's ratio of gallbladder stones and intrahepatic stones was higher than male's.The morbidity of cholelithiasis significantly increased in aged patients. The spectrum of cholelithiasis has changed significantly.

Objective To characterize the vascular cognitive impairment of stroke patients with different injury sites (right or left cerebral hemisphere) and pathological type (hemorrhage or infarct). Methods A total of 119 stroke patients were assessed with regard to their cognitive functions using the LOTCA within one week of admis-sion, and comparison was made among patients in terms of VCI characteristics, injury site, and pathological type. Results In patients with left hemisphere injury, there found no significant difference between those with cerebral in-farct and hemorrhage with regard to the total score of LOTCA, but the score of perception of those with hemorrhage was lower than those with infarct(P<0.05). in patients with right hemisphere injury, both total score of LOTCA and the subscore were not significantly different between those with infarct and hemorrhage(P>0.05). In patients with infarct in left hemisphere, the total score of LOTCA was lower than those with infarct in right hemisphere(P<0.05), but the scores of orientation and thinking operation were lower than those with infarct in right hemisphere(P<0.001 or <0.01). In patients with hemorrhage in the left hemisphere, the total score of LOTCA was not significantly different from those with hemorrhage in right hemisphere, but the scores of orientation and perception were lower than thosewith hemorrhage in right hemisphere(P<0.001 or <0.01). Conclusions More attention with regard to perception training should be paid to those with cerebral hemmorhage than those with cerebral infarct. In patients with cerebral infarct, more attention with regard to orientation and thinking operation training should be paid to those with infarct in left side, while for those with cerebral hemorrhage, more attention with regard to orientation and perception training should be paid to the left hemisphere insult.
