OBJECTIVETo study the impacts of electroacupuncture (EA) on memory impairment after cerebral infarction through the observation of hydrogen proton magnetic resonance spectroscopy (1H-MRS) of brain tissue metabolites in the patients of cerebral infarction.

METHODSSixty cases of memory impairment after cerebral infarction were randomized into an observation group and a control group, 30 cases in each one. The conventional rehabilitation training and medication were applied to all the patients. In the observation group, beside the basic treatment, EA was applied to bilateral Ezhongxian (MS 1), Dingzhongxian (MS 5), Dingniehouxiexian (MS 7), Hegu (LI 4), Taichong (LR 3), Zusanli (ST 36), Taixi (KI 3), Xuanzhong (GB 39) and Fengchi (GB 20). The treatment was given once a day, 5 times a week, for 8 weeks. The clinical memory scale was used for the score evaluation before and after treatment in all the patients. The magnetic resonance image (MRI) and 1H-MRS scanning were applied to the head. The ratio of N-acetyl aspartate (NAA) and creatine (Cr) and the ratio of choline (Cho) and Cr were determined in the foci of cerebral infarction.

RESULTSEight weeks later, the scores of clinical memory scale were all increased after treatment as compared with those before treatment in the two group (all P<0. 01). The ratio of NAA and Cr was increased as compared with that before treatment (P<0. 05); the ratio of Cho and Cr was reduced as compared with that before treatment (P<0. 05). The changes in the observation group were more obvious than those in the control group (all P<0. 05).

CONCLUSIONOn the basis of the conventional medication and rehabilitation training, EA improves the metabolism of brain tissue and memory function of the patients. The efficacy of this therapy is better than that of medication combined with rehabilitation training.

Objective To study the clinical effect of the combination of cataract ultrasonic emulsification and multifocal aspherical intraocular lens in cataract patients through evaluating different intraocular lenses elimi-nating spherical aberration. Methods 180 patients(180 eyes)with senile cataract were included between,2001 and 2005.The patients were divided into three group (n = 60 each),based on the admition time. Implantion of ReSTOR-SN60D3 is multifocal aspherical intraocular lens(SN60D3),implantion of SN60AT lens is single spheri-cal intraocular lens (SN60AT),and implantion of SN60WF lens is single aspherical intraocular lens (SN60WF group). Three months after operation,the refractive state,focus depth,modulation transfer function(MTF),and higher-order aberrations were measured ,and the visual quality were investigated. Results There was no signifi-cant difference in vision in three groups before operation(P > 0.05). After operation,the UCNVA of SN60D3 group was significantly better than the SN60AT group and SN60WF group(P < 0.05). Under 3 mm pupil diame-ter,spherical aberration of SN60D3 group and SN60WF Z(4,0)were less than SN60AT group(P < 0.05), SN60D3 group and SN60WF only under 5 CPD spatial frequency MTF(HOA)value was superior to the SN60AT group(P<0.05);The score of near vision,reliance on vision correction and limitation of operation of patients in SN60D3 group were higher than other two groups(P<0.05). Visual clarity and day vision fluctuations of patients in SN60D3 group is better than single focal sphere group(P<0.05). Conclusion In multifocal aspherical intra-ocular lens,general spherical aberrations and higher-order aberrations is smaller,effect of naked near vision is bet-ter and the rest of the vision is stable ,which can bring good visual quality for cataract patients after operation.

Objective To explore the characteristics and risk factors of type 2 diabetes mellitus (T2DM) onset in pedigrees. Methods A total of 865 subjects were screened and diagnosed by oral glucose tolerance test (OGTT) based on American Diabetes Association (ADA) criteria. Type 1 diabetes mellitus (T1DM) , maturity onset diabetes of the young (MODY) and chondriosome diabetes were excluded by clinical features and laboratory test of insulin and autoantibodies including glutamic acid decarboxylase antibody, insular cellular antibody and insulin autoantibody. A total of 182 pedigrees of T2DM were obtained. Results No gender difference was found in the prevalence of T2DM (42. 59% in male and 48. 18% in female respectively, P ＞0. 05) , nor was the newly diagnosed rate(9. 89% in male and 11. 82%in female, P ＞ 0. 05). The onset age was (63. 3 ± 12. 4) years old in the first generation [(64. 4 ± 12. 5)years in male and (62. 3 ± 10. 3) years in female] , (47. 1 ± 8. 7) years old in the second generation [(48. 2 ±9. 3)years in male and (46. 1 ± 8. 1) years in female] , (29. 6 ± 10. 2) years old in the third generation [(28. 9 ±9. 5)years in male and (30. 0 ± 10. 4)years in female]. Compared with normal glucose tolerance (NGT) subjects , newly diagnosed T2DM and impaired glucose regulation (IGR) subjects had higher prevalence of hypertension, hyperlipidemia and smoking but less physical activities. Statistical differences were shown in body weight five years before diagnosis, one years before diagnosis and at diagnosis in newly diagnosed T2DM[(68. 4 ±12. 4)kg, (69. 5 ± 11. 0)kg and (69. 1 ±9. 6)kg] and IGR[(66. 1 ±10.7)kg, (65.9 ± 10.7) kg and(65.7 ± 10.4) kg] , when compared with NGT [(61.0 ± 10.2) kg,(59. 5 ±11.0) kg and (60. 1 ± 10. 4) kg, all P ＜ 0. 05] . The same results were obtained with waist circumference and waist-hip ratio [(4. 1 ± 12. 5) cm and 0. 92 ± 0. 36 in newly diagnosed T2DM while (89. 1 ± 10. 7) cm and 0. 90 ± 0. 64 in IGR] , when compared with NGT[(82. 5 ± 10. 1) cm and 0. 82 ±0. 25] , all P ＜0. 05. Conclusions No gender difference was found in the onset characteristics of T2DM.High prevalence of obesity, hypertension, hyperlipidemia and smoking with less physical activities were associated with T2DM.

Objective To investigate the clinical features and treatment of Kaposi's varicelliform eruption. Methods Clinical data on 24 cases of Kaposi's varicelliform eruption were retrospectively analyzed.Results All the 24 patients were accompanied by different underlying skin diseases, including eczema in 17 cases and atopic dermatitis in 7 cases. PCR of vesicle fluid was positive for herpes simplex virus type 1 (HSV 1 ) in 16 (66.67%) patients, and culture of vesicle fluid or lesional exudates grew Staphylococcus aureus in 12 (50%) patients. Conclusion Infants with atopic dermatitis or eczema are rather susceptible to Kaposi's varicelliform eruption, which may be partly caused by herpes simplex virus infection.

Objective To investigate the correlation of plasma brain natriuretic peptide (BNP) level with serum albumin, serum total bilirubin and thrombin time in patients with liver cirrhosis.Methods RandomLy selected from January 2014 to June 2016 to our hospital diagnosis and hospitalization of 200 cases of cirrhosis patients, according to the standard of Child-Pugh classification provided by Chinese Medical Hepatology Division in 2006, 48 cases were Child A group, 96 cases were Child B group and 56 cases were Child C group.The plasma BNP, serum albumin, serum total bilirubin, prothrombin time and QTc interval of electrocardiogram were analyzed in the clinical data of each group of patients and the correlation between plasma BNP and their correlation.Results The levels of plasma BNP in Child A, B and C groups were higher than those in B group and B group.The correlation between plasma BNP and Child's grade showed a positive correlation, and the results of each group were statistically different (P<0.05).The plasma BNP level was negatively correlated with ALB ( P<0.05 ) .The level of plasma BNP was positively correlated with ALB ( P <0.05 ) .The correlation between plasma BNP and PTIL was correlated with TBIL.The correlation between plasma BNP and TBIL was significantly correlated with TBIL ( P <0.05), The higher the plasma BNP, the regression analysis showed that plasma BNP and TBIL were positively correlated, the difference was statistically significant (P<0.05).The correlation between plasma BNP level and QTc was analyzed.The QTc interval of plasma BNP level was higher than that of the control group ( P<0.01 ) , and the difference was statistically significant ( P <0.01 ) .Conclusion The plasma BNP level in patients with liver function is closely related to ALB, TBIL, PT, QTc interval, and has the value of evaluating and predicting liver function.

Background Bevacizumab and triamcinolone acetonide (TA) has been widely used in the treatment of diabetic macular edema (DME) clinically,but the effectiveness of both treatment has disadvantage.Therefore,some researchers try to combine bevacizumab with TA for the management of DME,but its efficacy is controversial.Objective This study was to evaluate the efficacy and safety of intraovitreal injection of bevacizumab combined with TA versus bevacizumab for DME.Methods The randomized controlled trials (RCTs) of bevacizumab combined with TA versus bevacizumab via intraovitreal injection for DME were searched from Pubmed,EMbase,Cochrane Library,CNKI.The methodological quality of the literature was evaluated according to evidencebased medicine (EBM),and the quality of the RCTs was appraised based on the Cochrane Handbook for Systematic Reviews of Interventions Version 5.0.The outcome indicators including the change values of central macular thickness (CMT) and best-corrected visual acuity (BCVA) as well as the safety indicators including topical and system adverse response of RCTs were analyzed with Cochrane Collaboration' s software RevMan 5.0.Results Nine RCTs were included with 665 eyes.The decrease value of CMT was more remarkable in the bevacizumab combined with TA group than that of the only bevacizumab group 12 weeks and 18 weeks after intravitreal injection (WMD =-44.69,95％ CI:25.27-64.11,P ＜ 0.000 001 ; WMD =-66.86,95％ CI:40.67-93.05,P ＜ 0.000 001).However,no significant differences were found in the change value of CMT in 6 weeks and 6 months after injection between the two groups (WMD =-15.40,95％ CI:-4.04-34.85,P =0.12 ; WMD =-2.57,95％ CI:-19.62-24.75,P =0.82).The improvement value of BCVA (LogMAR) in the bevacizumab combined with TA group was superior to that of the only bevacizumab group 6 weeks after injection (WMD =-0.04,95 ％ CI:-0.08--0.00,P =0.05),but there were no significant differences between the two groups at 12weeks,18 weeks and 6 months after treatment (WMD =-0.04,95％ CI:-0.12-0.05,P=0.36;WMD =-0.04,95％ CI:-0.11-0.03,P=0.28; WMD =0.03,95％ CI:-0.05-0.12,P=0.45).The incidence rate of transient anterior response after injection was not significantly different between the two groups (RR =0.89,95％ CI:0.49-1.60,P =0.70).Secondary ocular hypertension after injection occurred in 30 eyes in the bevacizumab combined with TA group,but no hypertension was seen in the only bevacizumab group.Conclusions Compared with only bevacizumab,intravitreal injection of bevacizumab combined with TA has a better efficacy in improving CMT but no obvious dominant in increasing BCVA for early DME.Intravitreal injection of bevacizumab combined with TA seemingly has a higher risk of inducing controllable ocular hypertension than administration of only bevacizumab.

AIM: In order to understand the pathological changes, characteristic of degeneration in optic nerve and retina after strike of optic nerve. METHODS: According to methods of Allen's spinal injury, a 600gcm-strike power was put on the intraocular portion of the optic nerve and created a striking injury on optic nerve. After a survival interval of 48 h, 1 week, 2 weeks, 4 weeks, 3 months, the animal's optic nerves and retinas were collected and fixed for morphological examination. RESULTS: Forty-eight hours after nerve injuries, the optic nerves were slight enlargement and vacuolation. In 1 week, the optic nerve began to degenerate in injured part and the glia cell had proliferated, but the forms of retinal ganglion cells(RGCs) were normal. In 2 weeks, the vacuolation and focal necrosis were appeared between nerve fiber. The number of RGCs began to decrease. Condensed nuclei presented in the retina. In three month, the diameter of the optic nerve decreased in injury part and collo-scar was formed. The phenomenon mentioned above was more obviously. The internal nuclear neurons and outer nuclear neurons appeared rare. The thickness of retina decreased. The number of RGCs began to decrease in 48 hours and progressed thereafter. It decreased about 3.35%, 13.23%, 19.74%, 23.20%, 29.28% in 48 h, 1 week, 2 weeks, 1 month, 3 months compared with the number of normal RGCs. RGCs began to apoptosis in 48 h. CONCLUSION: The model in this experiment could make definite uncompleted optic nerve and retina injuries. The degree of neuron injuries decreased from RGC, internal nuclear neurons to outer nuclear neurons. The number of RGCs began to decrease in 48 hours, and most quickly periods from 48 hours to one week.
