? AIM: To explore the curative effect of dacryocystorhinostomy under endoscopy with mitomycin for the treatment of chronic dacryocystitis.?METHODS: Totally 73 cases ( 78 eyes ) with chronic dacryocystitis were treated with dacryocystorhinostomy under endoscopy with mitomycin and followed up for 6-12mo.?RESULTS: In the 73 patients, 66 cases with 70 eyes (90%) were cured, 2 cases with 3 eyes (4%) improved, 5 cases with 5 eyes ( 6%) not changed. In the recurrent 5 eyes, 2 eyes were treated under endoscopy to remove granulation, enlarge the opening, then anesthetic tube was placed after cotton sheet with 0. 4g/L mitomycin was put on the incision for 5min. The rest 3 eyes were treated in superior hospital with laser, and all were successful. There was no severe complication observed.?CONCLUSION:Dacryocystorhinostomy under endoscopy with mitomycin for chronic dacryocystitis is effective.

Objective To investigate the influence of body temperature on the recovery from vecuronium-induced neuromuscular block.Methods Sixty-eight ASA I - II patients (39 male, 29 female) aged 19-69 yr undergoing elective surgery under general anesthesia were randomly divided into 2 groups: group I in which patients' body temperature was maintained at 37 ℃ using warming blanket; group II in which no measures were taken to maintain the patients' body temperature. The patients were premedicated with phenobarbital 2 mg?kg-1 and atropine 0.01 mg? kg-1 intramuscularly. Anesthesia was induced with fentanyl 5 ?g? kg -1, propofol 2 mg? kg-1 and vecuronium 0. 1 mg?kg-1 . After tracheal intubation anesthesia was maintained with inhalation of 0.8%-2.5% isoflurane and propofol infusion at a rate of 2-4 mg ? kg-1? h-1 .Neuromuscular block was monitored using accelograph (Biometer, Denmark) .The changes in TOF and T1 were monitored. T1was maintained at 10% by vecuronium infusion during operation. At the end of operation a bolus of vecuronium 80?g ? kg-1 was given intravenously and T1 was completely depressed. The time for T1 to returned to 5% ,25% and 90% and the time required for T1 to return from 25 % to 75 % were recorded. The total amount of vecuronium given was recorded. Temperature probe was placed in the esophagus ( core temperature) . The room temperature was also recorded. Results The body temperature was lower, the total dose of vecuronium was smaller and the vecuronium-induced neuromuscular block lasted longer in group II as compared with group I . There was close correlation between body temperature and vecuronium-induced neuromuscular block. Conclusions Lower core body temperature could prolong the vecuronium-induced neuromuscular block.

Objective To discuss the pathogenesis,diagnosis and treatment of delayed traumatic intracerebral hematoma.Methods The clinic data of traumatic delayed intracranial hematoma patients in this hospital were retro- spectively analyzed.According to clinic observation and CT re-examination,47 cases were diagnosed as delayed trau- matic intracranial hematoma(45 cases by operative treatment,and the other 2 by conservative treatment).Results There were 21 cases of recovery,10 cases of slight disability,8 cases of severe disability,8 cases of death.The total mortality rate was 17 %.Conclusion Brain contusion,subarachnoid hemorrhage and skull base fracture were impor- tant factors of DTICH.Fine-observation and prompt CT re-examination offered excellent results for DTICH.

Malignant tumor is one of the main causes for death in the world at present as well as a major disease seriously harming human health and life and restricting the social and economic development. There are many kinds of reports about traditional Chinese medicine patent prescriptions, empirical prescriptions and self-made prescriptions treating cancer, and prescription rules were often analyzed based on medication frequency. Such methods were applicable for discovering dominant experience but hard to have an innovative discovery and knowledge. In this paper, based on the traditional Chinese medicine inheritance assistance system, the software integration of mutual information improvement method, complex system entropy clustering and unsupervised entropy-level clustering data mining methods was adopted to analyze the rules of traditional Chinese medicine prescriptions for cancer. Totally 114 prescriptions were selected, the frequency of herbs in prescription was determined, and 85 core combinations and 13 new prescriptions were indentified. The traditional Chinese medicine inheritance assistance system, as a valuable traditional Chinese medicine research-supporting tool, can be used to record, manage, inquire and analyze prescription data.

According to the designed specific primers of gene fragment based on the Salvia miltiorrhiza transcriptome data, with the method of reverse transcription polymerase chain reaction (RT-PCR), this study cloned full-length cDNA sequence of 1-hydroxy-2-methyl-2-(E)-butenyl-4-diphosphate synthase gene from Salvia miltiorrhiza bge.f.alba, this sequence is named as SmHDS and its GenBank registration number is KJ746807. SmHDS, 2 529 bp long, contains an ORF of 2 229 bp, encodes 742 amino acids, including 5' UTR 170 bp and 3' UTR 130 bp. Using bioinformatics software, having made a homology analysis of the obtained sequence, we can have a conclusion that SmHDS have a close genetic relationship with HDS of Salvia miltiorrhiza. Analysis result of prokaryotic expression revealed that in Escherichia coli, SmHDS expressed target proteins which in size are comparable with the protein predicted. Meanwhile, the 4 factors which can influence the protein expression were optimized, the 4 factors are inducing temperature, inducing time, IPTG concentrations and density of inducing host bacterium (A600). The optimal expression conditions of SmHDS were 30 degrees C until the A600 is 0.6, and add IPTG to a final concentration of 0.2 mmol x L(-1), and the induction time of 20 h. It provides theoretical basis for the further study of the function of 1-hydroxy-2-methyl-2-(E)-butenyl-4-diphosphate synthase in the biosynthesis of tanshinone compounds.

OBJECTIVETo investigate the effects of advanced glycosylation end products (AGEs) modified bovine serum albumin (AGE-BSA) on the expression of reactive oxygen species (ROS) and monocyte chemoattractant protein-1 (MCP-1) in human renal mesangial cells (HRMCs).
METHODSHRMCs were cultured in vitro with medium containing different doses of AGE-BSA or BSA (50,100, 200, 400 mg/L) for 48 hours, or with AGE-BSA (200 mg/L) for different times (12, 24, 48, 72 h). Immunocytochemistry assay was used to estimate the protein level of RAGE. The ROS in cells were measured by flow cytometry and the mRNA expression of MCP-1 were analyzed by semi-quantiative reverse transcription-polymerase chain reaction (RT-PCR) after treatment with AGE-BSA or BSA.
RESULTSThe protein level of RAGE was upregulated in the HRMCs with AGE-BSA. The expression of ROS and MCP-1 significantly enhanced by incubation of AGE-BSA in a time- and dose-dependent manner. The effects of AGE-BSA-induced up-regulation of ROS and MCP-1 level was significantly blocked by neutralizing antibodies to RAGE, while the expression of ROS and MCP-1 stood nearly unchanged after cultured with huamn IgG.
CONCLUSIONThe expression of ROS and MCP-1 in HRMCs is induced by AGE-BSA through RAGE, which may have potential effects in the pathgenic mechanism of diabetic nephropathy.
