OBJECTIVE: To study the general pattern and characteristics of the ADR induced by lidocaine.METHODS: A total of 44 ADR cases caused by lidocaine reported in CHKD during 2002~ 2006 were collected and analyzed statistically. RESULTS: Lidocaine-induced ADR were mostly occurred in local anesthesia and block anesthesia,especially in the first time medication and within ten minutes.ADR could involve multiple organs and systems,and the clinical manifestations were complicated and diversified,which were mainly allergic reactions or even death in severe cases.CONCLUSION: Clinical physicians and pharmacists should be alert to the ADR induced by lidocaine and they should stick to the principle of rational drug use.

This study represents the first description of structural variations in the globin beta chains of 19 strains of inbred mice. The trypic pep tide mapping of beta chains of globin from BALB/c, BALB/cA, BALB/cJ, BALBcJ-nu, BALB/nu/ + ,BALB/cyJax,B10,B10A/sui,C57BL/6,C57BL/10snJ,SMMC/B,SMMC/C, C3H/He, CFW, DBA/2,SWI,Swars/nu/+,SSB and 129/sv strains of mice was established. The results showed that the position of peptide spots upon fingerprint mapping of beta chains was obviously different in comparison with each other. The different patterns of variability and polymorphism found in the various mouse species may then have come into being as a consequence of the action of selective forces on the various new beta chains which were created by some exchange processes.

Objective:We probe more direct operation pathways in sphenoidal sinus and saddle area, and take proper measures for correlated diseases which surpass scope of sphenoidal sinus by combining image data, which could prevent serious complication.Method:Under nasal endoscope, the operation approaches we adopted included trans-anterior ethmoid sinus-posterior ethmoid sinus-sphenoidal sinus pathway, trans-meatus nasi superior-posterior ethmoid sinus-sphenoidal sinus pathway, trans nasal septum-sphenoidal sinus pathway and trans-natural opening of sphenoid sinus anterior into sphenoid sinus pathway by taking upper edge of posterior naris as a consistent surgical landmark. Forty-six cases who had sphenoidal sinus mass with bone erosion recieved surgical treatment.Result:Twenty-one cases with cyst and pus cyst of sphenoidal sinus had been healed by trans-meatus nasi superior pathway;1 case with hematoma and organization in sphenoidal sinus had been cleared by trans-meatus nasi superior pathway;3 cases had hematoma and organization in sphenoidal sinus and pseudoaneurysm in internal carotid artery,one of them suffered fatal hemorrhage in surgical exploration, and cured by endovascular embolization, the other two only underwent nasal endoscopic examination,the diagnosis was established by DSA and they received interventional therapy;4 cases with papilloma in sphenoidal sinus had been treated by trans-natural opening of sphenoid sinus approach,and 3 cases were cured,1 case had only partial mass resection as the papilloma offended the outer wall of sphenoidal sinus diffusely;2 cases with cholesteatoma of sphenoid sinus have been removed completely by trans-meatus nasi superior approach;1 case with encephalomeningocele of sphenoidal sinus underwent sphenoidotomy by trans-natural opening of anterior of sphenoidal sinus, and intraoperative puncture showed characteristic cerebrospinal fluid,the exposed meninges were then repaird surgically;1 case with mycosis of sphenoidal sinus had been cured by thorough clearing of the leision in sphenoidal sinus combined with antifungal therapy;3 cases with malignancy of sphenoidal sinus had received major mass resection of sphenoidal sinus by trans-anterior ethmoid sinus-posterior ethmoid sinus approach, and followed with radio therapy and chemotheraphy;5 cases with NPC in-volving sphenoidal sinus had been treated by radio therapy and chemotherapy after pathological examinacation;5 cases with post-operative cerebrospinal rhinorrhea and granulation hyperplasia of sphenoidal sinus had been repaired successfully by trans-meatus nasi superior approach or tans-nasal septum approach.Conclusion:There are various surgical pathways to deal with sphenoidal sinus and correlated diseases under nasal endoscope.The operation will be direct, safe and minimal invasive if we choose the pathway properly. Thin slice CT scan and 3D reconstruction of sella, and DSA or angiography of brain before operation is one of effective means to prevent surgical complications for leisions beyond scope of sphenoidal sinus.

Objective To establish an animal model of PCOS and to detect the DNA methylation states of LHR, INSR and AR genes. Methods 24-days-old female Sprague-Dawley (SD) rats were randomly divided into two groups. The rats in the experimental group were given subcutaneous implanting of levonorgestrel silica gel staff and injected 1.5 IU hCG twice daily for 9 days from the 4th day. The rats in the control group were injected with normal saline at the same time. Ovarian morphologic changes, sex hormone levels, fasting serum insulin and glucose were detected. The LHR, INSR and AR genes' DNA methylation patterns were checked by methylation specific PCR in modeling group and control group. Results The ovarian weight and volume in modeling group were higher than those in control group. The ovaries in modeling group showed multiple follicular cysts, and the number of theca cells and interstitial cells increased. Less developed follicles and corpus lutea were seem. The serum level of progesterone, testosterone, luteinizing hormone, fasting insulin and glucose were significantly higher in experimental group than those in control group, so as the LH/FSH ratio and HOMA index. No methylation of LHR and AR genes were found in both groups. The methylation frequency of INSR gene (76.7%) was significantly higher in modeling group than that in control group (P<0. 001). Conclusion The depression of INSR gene's transcriptional induced by DNA methylation is important in the development of insulin resistance in PCOS.

AIM To investigate the protective effect of propofol on ischemia-reperfusion (I-R) injury in isolated rat hearts and clarify the possible molecular mechanism from oxidative stress and the apoptosis initiated by mitochondria pathway. METHODS The isolated Langendorff-perfused rat hearts were rendered globally ischemia for 25-min followed by 30-min reperfusion to establish I-R injury model. The cardiac function parameters were recorded. The swelling, integrity of electron transport chain (ETC) and content of malondialdehyde (MDA) in myocardium mitochondria were determined. The percentage of apoptotic cardiomyocytes and the expressions of Bcl-2 and Bax proteins were evaluated by flow cytometry. The expressions of caspases-8, -9 and -3 proteins in myocytes were detected by immunohistochemistry. RESULTS Compared with I-R group, perfusing with 30 and 60 μmol·L-1 propofol from 10 min before ischemia to whole reperfusion period resulted in improvement in cardiac function. The swelling and ETC lesion of mitochondria alleviated, and MDA content decreased. The percentage of apoptotic cardiomyocytes was markedly lower than that of I-R group. The expression of Bcl-2 protein was higher and the expression of Bax was lower than that of I-R group. The expressions of caspase-3 and caspase-9 proteins were obviously lower than those in I-R group. CONCLUSION Propofol confers significant protection against the I-R injury in the isolated rat hearts. Diminishing oxidative stress, protecting mitochondria from peroxidative injury, thus interfering with the mitochondria-dependent apoptotic pathway may be one of the major mechanisms of its cardioprotection.
