Objective　To evaluate the efficacy and safty of pegging hydroxyapatite orbital implants.Methods　Fourty-five patients who received drilling and pegging of hydroxyapatite orbital implants were studied retrospectively, and all patients used the peg and sleeve system followed-up 2 to 24 months.Results　The rate of success of the first operations is 82.2%. Complications associated with pegging included peg hole drilled on an angle, drilling off-center, drilled hole shallow, granuloma and infection, total complications occured in 22.2% in the review, most that are of a minor nature can be cured.Conclusions　The hydroxyapatite orbital implants can be directly coupled to the prosthesis through a peg system, allowing a wide range of prosthesis movement and giving a more lifelike quality to the prosthesis. When and how to drill and exactly hole on implant is the key for pegging.

Objective:To compare the efficacy and safety of ropivacaine and bupivacaine in combined spinal epidural anesthesia in abdominal operation. Methods:Totally 86 abdominal operation patients with combined spinal epidural anesthesia were randomly divid-ed into group A and group B with 43 ones in each. Group A was with ropivacaine anesthesia, while group B was with levobupivacaine anesthesia. The anesthesia effect, hemodynamic changes at different time points and adverse drug reactions were compared between the two groups. Results:The duration of sensory block in the two groups was not statistically different (P>0. 05), while the patients in group A had shorter motor nerve recovery time than those in group B (P<0. 05), and Bromege score of group A was significantly lower than that of group B (P<0. 05). After the onset of anesthesia block, all hemodynamic parameters (SBP, DBP and HR) in the two groups were lower than those before the anesthesia (P<0. 05), while at the end of anesthesia, the parameters showed no statistically significant difference from those before the anesthesia (P>0. 05). During the operation, the parameters at different time points in group A had no significant difference from those in group B (P>0. 05). The incidence of adverse drug reaction was not statistically significant between the two groups as well (P>0. 05). Conclusion:Ropivacaine and levobupivacaine show similar blocking effect on the sensory nerve with the same effects on hemodynamics and adverse reactions, however, the blocking effect of ropivacaine on motor nerve is weaker, which is more beneficial to the early exercise of the patients after operation.

Objective To investigate inhibitory effects of Oridonin on the proliferation of cultured rabbit conjunctival fibroblast (RCF). Design Experimental study. Participants Cultured RCF obtained from filtering area after trabeculectomy. Methods Trabeculectomy was performed in rabbits. On day 7 after surgery, subconjunctival tissue from filtering area was obtained for culturing RCF in vitro. Cultured RCFs were exposed to different concentration Oridonin (5, 10, 20, 30, 40, and 50 ?mol?L-1) for 48h, respectively. The proliferation of RCF was investigated by MTT assay at different time points. Main Outcome Measures Optical density (OD) value of RCF and inhibitory rate of cell growth. Results OD values of each concentration Oridonin group (5, 10, 20, 30, 40, and 50 ?mol?L-1) were (0.402?0.013), (0.347?0.011), (0.293?0.015), (0.236?0.022), (0.184?0.023), and (0.125?0.014), respectively. These data showed a significant difference compared with the OD value (0.453?0.015) of control group without Oridonin (P=0.021-0.000). The inhibitory effects showed a significant difference in a dose-dependent manner (F=5.48, P=0.003). Oridonin (5, 10, 20, 30, 40 and 50 ?mol?L-1) sup-pressed the proliferation of RCF in vitro at rates of 11.26%, 23.40%, 35.32%, 47.90%, 59.38% and 72.41%, respectively. Conclusion Oridonin can inhibit the proliferation of cultured RCF obtained from filtering area. The effect is in a dose-dependent manner. This indicates that Oridonin is most likely to be a novel agent to prevent excessive scarring following glaucoma surgery.

BACKGROUND: The role of p53 gene in human lung cancer has been confirmed. Since the discovery of p63 gene as the homologue of p53, its role and possible mechanism-have aroused the attention of investigators all over the world. But the principle concerning transcription and expression of p63 in small-cell lung carcinoma (SCLC) remains unclear.OBJECTIVE: To investigate the level of the expression of p63 gene in SCLC and lung adenocarcinoma tumor tissues, peri-carcinoma tissues and normal tissues, and observe the expression of p63 protein in these tissues so as to understand the principle and clinical significance concerning p63gene expression in SCLC and lung adenocarcinoma.DESIGN: Controlled experiment.SETTING: Department of Thoracic and Cardiovascular Surgery, Research Institute of Field Surgery of Daping Hospital of Third Military Medical University of Chinese PLA.PARTICIPANTS: Six SCLC specimens dissected during the surgical operation in Daping Hospital, Third Military Medical Univers ity of Chinese PLA, between October 2000 and September 2002 , were recruited. There were 4 male and 2 female patients aged 42 to 67 years (mean age of 50.7years); 15 specimens of lung adenocarcinoma were also collected at the same time. Tumor tissues, peri-carcinoma tissues and normal tissues were chosen in each specimen.METHODS: Reverse transcriptase polymerase chain reaction (RT-PCR)was used to detect and compare the transcription expression of two subtypes of p63 gene (TAP63 and △NP63)in the tumor tissues of 6 cases of SCLC and 15 cases of lung adenocarcinoma. At the same time, immunohistochemical staining technique was used to detect the expression of p63protein in the above tissues.MAIN OUTCOME MEASURES: ① Expression of p63 protein detected by RT-PCR in tissue specimens. ② Expression of p63 protein detected in tissue specimens detected by immunohistochemical staining technique.RESULTS: ① Expression of p63 protein detected by RT-PCR in tissue specimens: The positive expression of △Np63 gene could be found in 5cases (83%, 5/6) of SCLC cancer tissues and 1 case of SCLC peri-carcinoma tissues (17%, 1/6), and the expression of TAp63 was not observed in all of the tumor, peri-carcinoma and normal tissues of SCLC. There was no expression of △Np63 or TAp63 in tumor, peri-carcinoma and normal tissues of lung adenocarcinoma. ② Expression of p63 protein detected by immunohistochemical staining in tissue specimens: The positive expression rate of p63 protein in SCLC tumor tissues was significantly higher than that in lung adenocarcinoma tissues [83% (5/6), 17% (1/6), P ＜ 0.01].CONCLUSION: p63 gene shows positive expression in SCLC, among which the expression level of △NP63 is increased while the expression level of p63 protein is obviously higher in SCLC than in adenocarcinoma tissues, which may be related to its regulatory role in the occurrence and development of SCLC. It is presumed that△NP63 gene has high transcription expression level in SCLC, which might inhibit cellular apoptosis, promote the proliferation of tumors, play the role as an oncogene. It suggests that p63 may be one of the factors influencing the prognosis of SCLC.
