BACKGROUND: Resin filling, full crown and veneer are used in cosmetic restoration of anterior teeth. Doctors prefer resin because of its perfect clinical effect and small hurt. Some patients complain of sensitivity after rsein filling and we are interest in choosing a better resin with less sensitivity.OBJECTIVE: To compare the incidence of postoperative sensitivity and the difference of the patients' self sensitivity alter cosmetic restoration of anterior teeth with vital pulp by 3M-Z350 Nano-resin and 3M-Z100 composite resin. METHODS: A total of 112 teeth with vital pulp because of caries or traumatic tooth fractures of 68 patients demanding cosmetic restoration were selected from the Department of Endodontics, Stomatological Hospital of Luzhou Medical College from August to December 2006. The teeth were random divided into 3M-Z350 group and 3M-Z100 group, with 56 teeth in each group. 3M-Z350 nano-rasin and 3M-Z100 composite resin were used for cosmetic restoration of anterior teeth with vital pulp. Ryge criteria were used to evaluate the sensitivity to the cold stimulation following cosmetic restoration, and the level of pain was detected by the pain ruler.RESULTS AND CONCLUSION: Compared with 3M-Z100 group, the incidence of sensitivity and self-pain level were decreased in the 3M-Z350 group at 1 day, 1 week, and 1 month after restoration (P < 0.01 or P < 0.05). There was no significant difference in the sensitivity and self-pain level between the two groups (P > 0.05). Anterior teeth with vital pulp were well restored by 3M-Z350 nano-resin which might reduce the incidence of postoperative sensitivity.

Objective To investigate the factors for retinopathy in premature infants. Methods Ophthalmologic mydri was conducted in premature infants and acording to the international classification of ROP, they were diagnosed as ROP. The risk factors of the incidence of ROP were statistically and respectively analyzed. Results Among total of 47 patients, 11 patients were found retinopathy of prematurity. Conclusion The body weight is lower, the gestation is shorter, incidence of ROP is the higher.

Objective To investigate the effect of dexmedetomidine on postoperative renal function of patients with rheumatic heart disease following valvular heart surgery. Methods Fifty patients following valvular heart surgery were randomized into experimental group and control group,with 25 cases in each group. The patients in experimental group receiveddexmedetomidine 0.5 μg/kg infusion 15min before induction, and then 0.5 μg/(kg·h) infused to the end of surgery, while those in control group received the same amount of saline in the same way. Blood from central venous was collected before surgery, at the end of surgery, 24 h and 48 h after surgery in order to detect Src, BUN and Cys C and the length of ICU duration was also recorded. Results Src and Cys C of the patients in both groups obviously elevated 24h after surgery when compared with pre-operation , while BUN elevated at both 24 h and 48 h after surgery(P < 0.05). Compared with those in control group, Src, BUN and Cys C were lower in experimental group ( P < 0 . 05 ) , and the length of ICU duration was shorter (P < 0.05). Conclusion Dexmedetomidine could improve the postoperative renal function after valvular heart surgery and lead to a better prognosis.

Background and purpose:The patients with aggressive lymphoma who have a poor prognosis and unlikely to be cured with conventional chemotherapy. This study was aimed to evaluate the effect of high-dose etoposide in mobilization followed auto-SCT in treating refractory lymphoma. Methods:40 patients [median age 33 (13-61) years] with refractory non-Hodgkin’s lymphoma (NHL, n=32) or Hodgkin’s lymphoma (HD, n=8) received high-dose etoposide [VP16 10-15 mg/(kg·d)×2 d] in mobilization in our center. Remission status prior to mobilization was PD (n=40). The use of such granulocyte colony-stimulating factor [G-CSF, 5-10μg/(kg·d)] mobilized peripheral blood stem cells (PBSC) after high-dose etoposide until the end of leukapheresis. Peripheral blood stem cell was collected and frozen in-80℃refrigerator. All these patients received auto peripheral blood stem cell transplantation (auto-PBSCT). Conditioning regimen was BEAM (n=19, 47.5%) or CBV (n=21, 52.5%). Results:Twenty-eight pa-tients (70%) were assessable for response after high-dose etoposide at a median pretreatment time of 39 days (range 17-172 days), 12 patients (30%) had no response. Median follow-up of 28 (4-66) months, 16 patients (40%) reached CR after auto-PBSCT. Fifteen of the 28 patients (53.6%) who had response to high-dose etoposide reached CR, 4 patients (14.3%) reached PR, 9 patients (32.1%) succumb to progression of disease. One of the 12 patients (8.3%) who had no response to high-dose etoposide reached CR, 1 patients (8.3%) reached PR, 10 patients (83.4%) succumb to progression of disease. The estimated 1-year OS and EFS were 69%and 56.7%respectively, 2-years OS and EFS were 63%and 52%respectively. The prognosis of the patients who had no response to etoposide was poor. The estimated 1-year OS and EFS were 25%and 16.7%respectively. Two group of comparison differences have statistics signiifcance (P<0.01). Conclusion: High-dose etoposide could be used in refractory lymphoma as rescue therapy in mobilization. It can increase the EFS and OS of patients who had response. The hematopoietic stem cells collection and hematopoietic reconstitution are not affected by etoposide.

Objective To Investigate the concentration of VILIP-1 and NR2 peptide in the serum of patients with ischemic stroke , and to explore their clinic value in early diagnostic of ischemic stroke patients.Methods The levels of VILIP-1 and NR2 peptide were examined by ELISA ( enzyme linked immunosorbent assay ,ELISA) with suspicious TIA ( defined as a neurological deficit that resolved within 24 hours) or acute ischemic stroke patients ( within 72 hours of onset of symptoms ) 340 cases,102 healthy controls,98 patients with vascular risk factors and 35 patients with hemorrhagic stroke.Among all the groups , VILIP-1 and NR2 peptide level were analyzed using the nonparametric Wilcoxon test.Diagnostic performance were analyzed among the groups with the two biomarkers independently and combinedly .Results Serum levels of VILIP-1 and NR2 peptide in patients with ischemic stroke (IS) were 9.80 (1.90-14.22) μg/L, 14.40 (5.60-27.91) μg/L respectively,which was higher than that of the healthy control group [VILIP-1:0.02 (0.01-0.09),NR2:0.33 (0.02-1.15),χ2 were 5.61 and 9.54,P<0.001],the group with vascular risk factors [VILIP-1:0.03 (0.02-0.16),NR2:0.27 (0.01-1.54),χ2 were 6.74 and 10.62,P<0.001], the group of patients non-stoke [VILIP-1:0.04 (0.03-0.19),NR2:0.53 (0.45-1.21),χ2 were 3.78 and 7.63, P <0.001 ].The levels of VILIP-1 and NR2 peptide was significantly increased in IS patients presenting within 3 h of symptom onset.When differentiating IS from patients with hemorrhagic stroke ,NR2 had a AUC of 0.934,showing a strong distinguishing effectiveness.Differentiating IS from healthy controls , patients with vascular risk factors and non-stroke patients,the AUC of combination of VILIP-1 and NR2 was 0.974,which was higher than the AUC of either VILIP-1(0.849) or NR2(0.862) alone(P <0.05). Conclusions VILIP-1 and NR2 peptide are very sensitive and specific biomarkers to the early diagnosis of IS.The combination of VILIP-1 and NR2 peptide has higher value of clinical applications than one of them independently.

OBJECTIVETo explore the effect of half circle external fixation for the treatment of open tibial fractures.

METHODSFrom March 2005 to March 2011, 94 patients with open tibiofibula fractures were treated by closed manipulative or Kirschner-wire poking reduction with half circle groove external fixation including 63 males and 31 females with an average age of 39 years old ranging from 17 to 65 years old. Among these patients, 5 cases were cross shaped fractures, 19 were oblique form and spiral fractures, 70 cases were comminuted fractures. According to the fracture Gustilo classification, 49 cases were type IIIA, 45 were type IIIB. The incidence of wound infection, fracture healing time were observed. The function was evaluated according to the Johner-Wruhs standard.

RESULTSAll patients were followed up for 14 to 63 months (averaged 29 months). The wound healing time was from 16 to 39 weeks (means 21.4 weeks). No fracture nonunion, osteomyelitis and calf compartment syndrome occurred. The wounds of 81 cases were healed at the first period,deep wound infection occurred in 2 cases. According to the function Johner-Wruhs evaluation criteria:the result was excellent in 52 cases, good in 37 cases, fair in 5 cases.

CONCLUSIONClosed manipulative or Kirschner-wire poking reduction and half circle groove external fixation can reduce the infection rate of open tibiofibula fractures. For open tibiofibula comminuted fractures, after the half circle groove external fixation for 3 to 6 weeks, a middle Kirschner-wire was removed according to fracture end healing situation to make fixation dynamic and promote fracture healing.

Objective To examine the distribution of bacterial species and antimicrobial susceptibility profile of pathogens in febrile neutropenic patients.Methods A total of 355 bacterial strains were isolated from febrile neutropenic patients in Shanghai General Hospital from January 2005 to December 2012. Antimicrobial susceptibility testing was done by Kirby-Bauer method. The susceptibility testing results were analyzed according to CLSI 2014 breakpoints.Results Gram-negative bacteria accounted for 70.4% of the 355 isolates, while gram-positive organisms accounted for 29.6%. The most common bacterial species werePseudomonas aeruginosa, Klebsiella pneumoniae, Acinetobacter baumannii, Escherichia coli, Stenotrophomonas maltophiliaand Staphylococcus haemolyticus. Non-fermentative bacteria accounted for 53.2% of all the gram-negative bacterial isolates. All theEnterococcus and
Staphylococcus isolates were susceptible to linezolid, vancomycin and teicoplanin. All theStaphylococcus strains were resistant to methicillin.P. aeruginosa isolates were relatively more susceptible to cefoperazone-sulbactam, piperacillin-tazobactam and cefepime (>70%) than imipenem (40.8%) and meropenem (59.2%). All theK. pneumoniae isolates were susceptible to imipenem and meropenem and more than 70% of the isolates were susceptible to cefoperazone-sulbactam, amikacin. More than 80% of theA. baumannii isolates were susceptible to carbapenems, cefoperazone-sulbactam, amikacin, ciprolfoxacin and aminoglycosides. All the E. coli isolates were susceptible to carbapenems and more than 70% were susceptible to cefoperazone-sulbactam and ceftazidime. More than 90% of theS. maltophilia strains were sensitive to levolfoxacin, minocycline, cefoperazone-sulbactam and trimethoprim-sulfamethoxazole.Conclusions Our data suggest that gram-negative bacteria, especiallyEnterobacteriaceae and non-fermentative bacteria, are still the primary pathogens in febrile neutropenic patients. Antimicrobial resistant strains are prevalent. Such data of bacterial species and antimicrobial susceptibility proifle of pathogens in febrile neutropenic patients are useful for empirical antimicrobial therapy of such infections.

Objective To investigate the clinicopathological characteristics, diagnosis and treatment of primary duodenal malignant tumors (PDMTs). Methods The clinical data of 47 PDMTs confirmed by pathology were retrospectively analyzed. Results Pathological types were adenocarcinoma in 42 cases, leiomyosarcoma in 4, and carcinoid in 1.The most common location of the tumor was the descending portion (35), especially the peri-papillary region (28) of the duodenum. The most common symptoms and signs were abdominal pain, jaundice, upper gastrointestinal hemorrhage, obstruction ,and weight loss. The main diagnostic modalities were gastroduodenoscopy, GI barium meal, ERCP, ultrasound (US) and CT. US together with ERCP was the most useful in improving the diagnosis of peripapilla tumors in the duodenum. Panceraticoduodenectomy and some palliative procedures were performed for 25 and 20 cases, respectively.Surgical mortality and postoperative morbidity were 2.2% (1/45) and 20% (9/45),retrospectively. The 3-year and 5-year survival for those adenocarcinoma without distant metastasis undergoing pancreaticoduodenectomy were 50% and 32%. No long survival was found after the palliative operation. Conclusions Adenocarcinoma is the most common pathological type of PDMTs.No specific symptoms were shown in the early stage of PDMTs, US, CT and ERCP are the main diagnostic procedures. Radical pancraticoduodenectomy can prolong survival time and should be attempted for those without systemic dissemination.Palliative operations should be considered for tumors in advanced stage.

Objective To explore the effects of thiamine and riboflavin on H2O2-induced DNA oxidative damage in human umbilical vein endothelial cell line ECV304.Methods ECV304 cells were incubated with 10,100,500,1000 mg/L of thiamine or 20,100,300,500 nmol/L of riboflavin for 24 h,and then oxidative damage of cells were induced by 25 mol/L H2O2 for 30 min.DNA damage was detected with single cell gel electrophoresis(SCGE)assay.ECV304 cells incubated without H2O2,thiamine and riboflavin were served as negative controls,and those incubated with H2O2 and without thiamine and riboflavin were served as positive controls.Results H2O2 induced DNA damage,and the indices of percent of DNA damage cells,percent of tail DNA,tail length and Olive tail moment were increased.The indices of cells pretreated with 10,100,500 mg/L of thiamine or 20,100,300 nmol/L riboflavin were significantly decreased(P0.05).Conclusion Proper supplementation of thiamine and riboflavin may decrease H2O2-induced DNA oxidative damage,while excess thiamine and riboflavin supplementation may be harmful to DNA and enhance the susceptibility to H2O2 potentially.
