Subjective visual perceptions experienced by patients during cataract surgery under local anesthesia have been given more and more attention now.Intraoperative visual experiences,including non-light perception,light perception,one or more color sensation,flash,movement,instrument,hands or fingers of surgeon etc.,are complained in parts of patients.These sensations and experience often lead to a fear of patient.Being aware of these intraoperative sensations of fear from patient is necessary for us to take the preventing strategy in advance.In addition,counseling of these patients prior to surgery may alleviate fears and improve the satisfaction of patient with surgery outcome.This paper reviewed the current studies on this phenomenon,discussed its clinical implications and possible mechanism,and suggested novel approaches to reduce its negative impact on the surgery.

AimTo observe the effect of infiltration of Methylprednisolone on injured spinal nerve root and the protective function of Methylprednisolone to non-impressed spinal nerve root lesion. Methods The spinal nerve roots were injured in 20 rabbits. Three days later local Methylprednisolone infiltration of spinal nerve root profromed in rabbits in experiment group, while rabbits in the control roup received equal amount of 0.9% natriichloridi instead. The conduct velocity of spinal nerve root was measured one week after operation. The histological change of spinal nerve root and immunohistochemical stain of posterior horn of spine were observed by microscope. Results The conduct velocity was recovered obviously in experiment group. In observation of spinal nerve we found the edema and hyperaemia of matrix were impaired obviously, the lesion focus was minimized, the amount of inflammatory cells was decreased. The area of substance P positive fiber and its terminus in posterior of spinal was smaller in experiment group remarkably than in control group. ConclusionsThe local infiltration of Methylprednisolone can relieve inflammation, inhibit the transmission of pain and accelerate recovery of spinal nerve root.

OBJECTIVE　To assess the efficacy and safety of Lipobay (cerivastatin) and Jingbishuxin (simvastatin) on lipid profiles.METHODS　40 patients with hypercholesterolemia were randomizedly divided into Lipobay group (0.3 mg,QN) and Jingbishuxin group (domestic simvastatin tablet) (20 mg,QN)for 4 weeks.Total cholesterol (TC),low density Lipoprotein cholesterol (LDL-C),triglyceride (TG) and high density lipoprotein cholesterol (HDL-C),blood sugar,hepatic and renal function,blood and urine regular test were measured before and after the treatment.RESULTS　After 4 weeks of treatment,TC,LDL-C and TG were reduced by 29.02%,29.95%,17.21% in Lipobay the group and 22.48%,28.68%,14.74% in Jingbishuxin group,respectively.Compared the measurements after treatment with that before treatment,there were significant differences in both groups,but there was no significant difference between them.No serious adverse effect was found.CONCLUSION　Lipobay had a same efficacy and safety on lipoprotein profiles as that of Jingbishuxin in elderly.It has a good tolerance with smaller dose.

Objective To analyze the impact of extent of mitral valve stenosis on the short and longterm outcome of percutaneous balloon mitral valvuloplasty (PBMV) in patients with mitral valve stenosis.Methods Two hundred and eighty-four patients with mitral valve stenosis were divided into two groups according to the Wilkins scoring system,and 191 cases whose score ≤8 were classified as group A,while the rest were classified as group B.All the patients were using the modified Inoue balloon method.Patients of successful PBMV were followed up at least 48 months and the efficiency was compared between two groups.Results The success rate of PBMV was 97.9％(187/191) and 92.5％(86/93) in group A and group B,there was significant difference between two groups (P ＜ 0.05).Echocardiography parameters improved significantly in both groups at 6 months after PBMV compared with those before PBMV (P＜ 0.05).Compared with those in group A,the changes of left atrial mean pressure [(14.31 ± 4.79) mm Hg (1 mm Hg =0.133 kPa) vs.(15.42 ± 5.14) mm Hg],across the valve pressure difference [(9.18 ± 4.66) mm Hg vs.(10.21 ± 4.38)mm Hg],pulmonary arterial systolic pressure [(26.21 ± 8.76) mm Hg vs.(32.04 ± 9.58) mm Hg],mitral valve orifice area [(1.01 ±0.16) cm2 vs.(1.21 ±0.18) cm2] after PBMV in group B were less (P＜0.05).Long-term follow-up (48-92 months) was completed in 273 successful cases and echocardiography parameters after PBMV improved significantly in both groups compared with those before PBMV during follow-up (P＜ 0.05).Compared with those in group A,the changes of left atrial mean pressure [(12.91 ±5.00) mm Hg vs.(15.1 7 ± 5.14) mm Hg],across the valve pressure difference [(7.26 ± 4.58) mm Hg vs.(9.63 ± 4.22) mm Hg],pulmonary arterial systolic pressure [(20.54 ± 7.68) mm Hg vs.(29.11 ± 8.53)mm Hg],mitral valve orifice area [(0.92 ±0.15) cm2 vs.(1.09 ±0.18) cm2] after PBMV in group B were less (P＜ 0.05).The incidence of mitral restenosis was also significantly higher in group B than that in group A [19.8％(17/86) vs.8.0％(15/187)],and there was significant difference (P ＜ 0.05).Conclusions The extent of mitral valve stenosis plays a key role on the outcome of PBMV in patients with mitral valve stenosis.Patients with lower echocardiography scores benefit more from PBMV than patients with higher echocardiography scores.

Aim To observe the expressions of KLF4 in the myocardium of diabetic mice and their changes under Tongxinluo capsule intervention. Methods For-ty KK/Upj-Ay mice were randomly divided into diabet-ic model group(n=10)and diabetic model with Tongx-inluo(TXL low,middle,high) groups(n =10,respec-tively). C57BL/6 mice were selected as control group ( n=10 ) . At the end of the 3 th month the mice were sacrificed and were weighed. The fasting blood-glucose (FBG),glycosylated hemoglobin(HbA1c),triglyceride ( TG) ,total cholesterol ( TC ) and insulin ( FINS ) were measured to calculate HOMA-IR. Radioimmunoassay was used to measure serum TNF-αand IL-6 . The path-ological changes in the myocardium of mice were ob-served by HE staining. KLF4 mRNA was examined by Real-time PCR, while KLF4 and NF-κB protein were measured by Western blot. Results Compared to the control group,FBG,HbA1c,TG,TC,FINS,HOMA-IR,
TNF-α and IL-6 in model group were markedly in-creased;the expressions of myocardial KLF4 were markedly decreased and the expression of nuclear NF-κB protein were markedly increased ( P < 0. 01 ) . Tongxinluo capsule could significantly reduce myocar-dial pathological damage, FINS, TG, TC, TNF-α, IL-6 level and the expression of nuclear NF-κB protein and up-regulate the expression of KLF4 ( P <0. 05 ) , but had no effect on FBG and HbA1c(P>0. 05). Conclu-sions KLF4 may be involved in the development of myocardial injury during diabetes. Tongxinluo capsule can ameliorate the myocardial damage and improve the function of diabetic myocardium by up-regulating the expression of KLF4 and inhibiting the activation of NF-κB inflammatory signal pathway.
