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 approach the methods of difficult laparoscopic cholecystectomy.[Methods ]The clinical data of 116 patients with Mirizzi syndrome,severe adherence of abdominal cavity and Calot'triangle,liver cirrhosis underwent difficult laparoscopic cholecystectomy since 2004 were retrospectively analyzed.[Results]Except 3 patients treated by abdominal operation,other patients were treated by laparoscopic cholecystectomy successfully.[Conclusion]The rates of open operation midway and complications are not increased in difficult laparoscopic cholecystectomy as long as dealing with them properly.

ObjectiveTo investigate the expression of Twist and N-cadherin in pancreatic cancer,and to study its relationship with clinicopathological parameters and patients' prognosis.Methods The expression of the Twist and N-cadherin in 62 tissue samples from patients with pancreatic ductal adencocarcinoma and 10 normal pancreatic tissue samples was determined by using immunohistochemistry MaxVision two step method,and the relationship with clinicopathological parameters and patients' prognosis was analyzed.ResultsThe positive expression rate of Twist in pancreatic cancer was higher than that of normal pancreatic tissues (96.8％ vs.30％,P ＜0.01 ),and the positive expression rate of N-cadherin was higher than that of normal pancreatic tissues (75.8％ vs.0,P ＜0.01),but there was no correlation between them (r =0.100,P =0.441 ).The expressions of Twist and N-cadherin was significantly correlated with TNM stage,lymph node metastasis,infiltration of portal vein or nerves and tumor location ( P ＜0.05 ),but not with age,gender and degree of differentiation ( P ＞ 0.05 ).The post-operative survival of patients decreased with the increasing Twist expression,but the survival was not associated with the expression of N-cadherin.TNM stage,the expression of Twist was independent predictive factors of prognosis for pancreatic cancer patients.ConclusionsTwist and N-cadherin are highly expressed in pancreatic cancer,and the expression was associated malignant behavior of pancreatic cancer.The abnormal expression of Twist may be a potential marker for prognosis evaluation of pancreatic cancer patients.

Objective:To classify the types of radiographic feature of central salivary gland type malignant tumors of the jaws(CSMTJ) with studying the clinical data,radiographic characteristics and pathological classifications,and to help the diagnose CSMTJ correctly and effectively in future. Methods:The clinical,radiological and pathological features of 62 cases of CSMTJ were studied and summarized. Among these cases,52 cases were collected from the medical records of patients of the internal databank according to the World Health Organization (WHO) Histological Classification of Salivary Gland Tumors standard and 10 cases of CSMTJ were from Guangdong Provincial Stomatological Hospital. Results:The maxilla to mandible ratio was 1∶1.7,Among CSMTJ cases,central mucoepidermoid carcinoma of the jaws (CMCJ) was the most common pathological type and the second was central adenoid cystic carcinoma of the jaws(CACCJ). 62 cases of CSMTJ could be classified into four types:Unicystic type,Multicystic type,"Flame shape" type and Osteolytic type. Conclusion:The radiographic presentation of CSMTJ was very complicated and its classification was connected with tumor malignant degree. The classification was very helpful to determine the treatment methods and the prognosis of the CSMTJ.
