Methods A total of 84 patients with optic nerve injury were divided into control group (n=47, received the general treatments) and treatment group (n=37, treated with hyperxia liquid on the basis of the general treatments) that were monitored regularly by VEP at days 1, 7, 14 and 21 respectively after treatment to analyze and compare latency, amplitudes, visual acuity and treatment result. Results After injury, abnormality of VEP occurred at days 1-7, reached the peak at days 7-14, and then markedly relieved at day 21. Compared with control group, degree of VEP abnormality was significantly lower (P

Background Studies show that retinal neurodegeneration may precede retinal microvascular changes in diabetes mellitus.The apoptosis of retinal ganglion cells (RGCs) is an early finding in retinal neurodegeneration.Toll-like receptor 4 (TLR4) is proved to be up-regulated in diabetic rats retina.However,the impact of TLR4 on RGCs damage in retinal neurodegeneration is poorly understood.Objective The aim of this study was to investigate the expressing change of TLR4 induced by high glucose in RGCs in order to offer a basis for the prevention diabetic retinal neurodegeneration and the study on targeting drugs.Methods RGCs were isolated and purified from the retinas of SPF SD rats aged postnatal 1-3 days by using papain digestion method and then were identified by immunofluorescence technology to detect the expression of Brn3a,a specific marker of RGCs.The cells were divided into normal control group and 10,20,30 mmol/L glucose groups.The expressions of TLR4 mRNA and protein in the ceils were detected by real-time fluorescence quantitative PCR and Western blot analysis in 24 and 48 hours after addtion of glucose.All procedures performed in studies were in accordance with the Association for National Institutes of Health (NIH) Statement for the Care and Use of Laboratory Animals recommendations.The protocol was approved by the Ethics Committee of Renmin Hospital of Wuhan University.Every effort was made to minimize animal discomfort and stress.Results The normal cells grew well with the shape of near roundness after inoculaton.The cells were gradually enlarged and clustered with obvious axons and dendrites 24 hours after purifying.Brn3a showed the positive expression in cultured cells.At 24 hours and 48 hours after glucose culture,the cell structures were gradually invisible in most cells.The expressions of TLR4 mRNA in the cells were 0.945 ±0.237,1.180±0.193 and 0.827±0.213 at 24 hours and 1.509±0.422,2.433±0.617 and 1.435±0.410 at 48 hours after culture in the 10,20 and 30 mmol/L glucose groups,respectively,which were significantly higher than 0.600±0.099 and 0.724±0.302 in the normal control group (all at P＜0.01).The expressions of TLR4 protein in the cells were 0.442±0.147,0.626±0.128 and 0.330±0.153 at 24 hours and 0.464±0.121,0.930±0.441 and 0.394±0.158 at 48 hours after culture in the 10,20 and 30 mmol/L glucose groups,respectively,which were significantly higher than 0.090±0.050 and 0.094±0.070 in the normal control group (all at P＜0.01).Conclusions A large number of RGCs die in a high-glucose environment in vitro,meanwhile,the expression of TLR4 up-regulates in the cells,indicating that TLR4 maybe participate in the damage of RGCs induced by high glucose.

Compared with C3 plant,C4 plant had evident growth advantage,higher rates of water and nutrition using,and higher bio-yield than C3 plant,Sugarcane was one of the typical C4 plants.DNA was extracted from sugarcane leaves,primers were designed by the cDNA sequence of PPDK gene from GenBank.Then DNA was amplified by LA-PCR(Long Acute PCR) method,ligated into pMD18-T vectors,and transformed into E.coli.JM109.Full-length PPDK gene sequence of sugarcane was obtained,the sequence was 13.5kb in length.For convenient of the next experiment,two digest sites(XhoI and NotI) were introduced into primers,the full-length PPDK gene was splitted to two parts,and was ligated into pMD18-T simple vectors,respectively.Whole PPDK gene clone of sugarcane was finished.The strains were storaged in the lab.

Objective To study on the effectiveness of endoscopic ultrasonography(EUS)in detec- ting insulinoma preoperatively.Methods Fifteen patients with clinical and biochemical signs of insulinoma were examined by EUS using a radial-scanning ultrasound endoscope and abdominal ultrasonography,CT, DSA prior to surgery.The outcome was evaluated on the basis of surgery and examination of the resected specimens.Results Fifteen patients with 16 lesions of insulinoma were identified by surgery and pathology. The aceuraey of diagnosis with EUS was 13/15(86.7%),and that with B-US,CT,DSA was 3/15(20%), 5/15(33.3%),9/14(64.3%)respectively.In the 14 lesions identified by EUS,10 lesions were depicted to be hypoechogenic,1 lesion was isoechogenic and 3 lesions were hyperechogenie.All 14 lesions were well demarcated and surrounded by normal pancreatic tissue.The minimum size of the lesion visualized by EUS was 0.5cm.Ten lesions were correctly detected by EUS with size of 0.5～2.0cm.EUS missed diagnosis in 2 lesions not for their small size.EUS falsely indicated a 10mm lesion from two lesions inside the head of pancreas.One lesion outside the pancreatic tail and one lesion in the pancreatic head were missed by EUS in another case.Conclusion EUS is superior in assessing the location of pancreatic insulinoma than other ima- ging methods such as B-US,CT,DSA.

Objective To evaluate the diagnostic value of EUS in patients with chronic abdominal pain of suspected pancreatic origin.Methods The EUS findings and related clinical data of 106 patients with chronic abdominal pain of suspected pancreatic origin(excluding the patients with suspected pancreatic malignancies)from 1991 to 2004 in PUMCH were retrospectively analyzed.Results(1)The principal dis- ease interpreting the chronic abdominal pain of suspected pancreatic origin(excluding pancreatic malignan- cies)was chronic pancreatitis(CP)(57.5%),the following contributions were other pancreatic diseases (18.9%)and unknown diseases(11.3%).(2)The sensitivity and specificity of EUS for diagnosing CP was 95.1% and 64.4% respectively,the positive predictive value(PPV)and negative predictive value (NPV)was 78.4% and 90.6% respectively.(3)Abhormalities of pancreatic parenchyma structure based on EUS were the main findings(90.2%)in patients with CP and non-homogeneous echo pattern combined with hyper echoic dots or calcification was the predominant feature(52.5%).The value of isolated inhomo- geneity and focal enhanced eehogenicity for diagnosing CP were limited(P＞0.05).Abnormalities of pan- ereatic ductal system were presented in 63.9% of patients with CP and dilation of pancreatic duct was the major feature(34.4%).CP with focal mass(inflammatory pseudotumor)was usually presented as hypo e- choic mass in the pancreatic head based on EUS(90%),which was similar to the EUS feature of pancreatic cancer.(4)The general accordant rate based on EUS with ERCP or BT-PABA were 77.8% and 70.4% re- spectively,and the correct rate based on combine diagnosis were 100% and 95.2%.Conclusion CP is the main source of chronic abdominal pain of suspected pancreatic origin(excluding pancreatic malignancies). EUS has good sensitivity but inadequate specificity for diagnosing CP,while ERCP may be more sensitive than EUS for detecting pancreatic ductal lesions.Pancreatic parenchymal abnormalities contribute the major EUS features of CP but the value of isolated inhomogeneity and focal enhanced echogenicity for diagnosing CP are limited.

This study aims to explore the impact on patient's liver and kidney function by different dosage of Kudiezi injection. This study retrospectively analyzed 15 228 patients' records from 18 nationwide general hospital information system (HIS). All patients were treated with Kudiezi injection, 1 956 patients that were given doses of > 40 mL, which is above the recommended dose, acted as the observation group. Fifty-five patients receiving the recommended dose of < 40 mL were the control group. Data about alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (Cr) and blood urea nitrogen (BUN) were collected before and after using Kudiezi injection, changes after treatment were outcomes. Also recorded were: age, costs, length of hospitalization and the patients' condition on admission. Propensity score method was used to balance 71 confounding variables such as gender, age, mortality, and costs. There were no significant difference on the four indexes between the two groups. It is hard to conclude that the use of Kudiezi injection over the recommended dose could influence the four indexes of liver and kidney from this data analysis. More conclusive evidence should be collected by further prospective study.
