A reasonable method for the quality control of tablets of Ginkgo biloba leaves was established in this paper. The total flavonol glycosides and terpene lactones of G. biloba tablets were quantified by HPLC. Totally, 16 batches of the commercially available tablets of G. biloba leaves were determined. Among of them, 2 batches were unqualified in the content of total flavonol glycosides, and 3 batches were unqualified in the content of terpene lactones. A validated HPLC fingerprint method was established to evaluate the commercially available tablets of G. biloba leaves with the assistance of LC-MS. Sixteen batches showed the similarity of 0.763-0.989. There were 31 fingerprint chromatogram peaks were identified as flavonoids compositions by LC-MS. This provides a research idea for the quality control of tablets of G. biloba leaves.

OBJECTIVETo evaluate the utility of neuronavigation in the microsurgery for cerebral cavernous malformations.

METHODSIn a retrospective study, 47 patients with cavernous malformations were involved from January 1995 to December 2010. Fourteen cases admitted into hospital from January 1995 to December 2002 were treated without neuronavigation (conventional group), the focus localization was based on magnetic resonance imaging (MRI) images, anatomic landmarks, and the experiences of the neurosurgeon. In the other 33 cases admitted after February 2002 to December 2010, surgeries were performed with neuronavigation using the Medtronic Stealth Station TREON or TRIA system (neuronavigation group). Excision of the cavernomas were all performed microsurgically, surrounding gliotic rim and hemosiderin stained tissue were resected in the case of epilepsy, and a few patients underwent extended hippocampal resection or multiple subpial transection.

RESULTSWith the use of neuronavigation, the extent of craniotomy reduced from 5.2 cm to 3.6 cm (P < 0.01), and deeper cavernoma focuses could be treated surgically. There were no changes with regard to the mean size of the cavernomas, the mean time of surgery and hospital stay (P > 0.05), but the mean time of anaesthesia was prolonged from 164 min to 197 min (P < 0.01). Cavernomas were resected completely in all 47 cases, which was confirmed by postoperative MRI recheck. The conditions of all patients were improved or remain unchanged, and no significant differences in the clinical outcome could be evaluated between the two groups.

CONCLUSIONSApplication of neuronavigation-assisted microsurgery of intracranial cavernous malformations surgery, helps reduce the surgical trauma, and has security and reliability.

OBJECTIVETo observe the effect of moxibustion combined with intermittent urethral catheterization on vesical function in the patient of neurogenic vesical dysfunction.

METHODSSeventy-six cases were randomly divided into an observation group and a control group, 38 cases in each group. The control group was treated with routine intermittent urethral catheterization and the observation group with the intermittent urethral catheterization and moxibustion on Guanyuan (CV 4), Mingmen (GV 4), Zusanli (ST 36), etc. Changes of residual urine volume, white cell count and the balance state of the urinary bladder were selected as the indexes of therapeutic effect and the therapeutic effects were compared between the two groups.

RESULTSThe total effective rate was 97.4% in the observation group and 79.0% in the control group with a significant difference between the two groups (P < 0.05); after treatment, there were significant differences between the two groups in the residual urine volume, the bladder volume and the case numbers reaching to the functional balance state of bladder (all P < 0.05), and there was no significant difference between the two groups in white cell count change (P > 0.05).

CONCLUSIONMoxibustion combined with intermittent urethral catheterization can significantly improve vesical function in the patient of neurogenic vesical dysfunction, reducing residual urine volume, increasing volume of bladder, promoting the balance state of vesical function, but it is basically same as intermittent urethral catheterization in prevention of urinary infection and therapeutic effect.

AIM: To investigate the synergistic antitumor effect of sinomenine(SIN)and cisplatin(DDP) against human fibrosarcoma HT-1080 cells and its possible mechanism.METHODS:CCK-8 assay was used to detect the cytotoxic effect of SIN and DDP in HT-1080 cells,and the combination index(CI)of SIN and DDP was analyzed by Chou-Talalay method.The apoptosis was analyzed by flow cytometry.The protein levels of copper transporter 1(CTR1),gluta-thione S-transferase-π(GST-π),Bcl-2 and Bax were determined by Western blot.RESULTS: At 48 h after treatment with SIN or DDP at various concentrations,the cell viability was remarkably reduced(P<0.05), and the IC50values of DDP and SIN were 6.50 μmol/L and 1.06 mmol/L, respectively.When the inhibition rate of HT-1080 cells exceeded 25%, SIN in combination with DDP produced a synergistic effect(CI<1).Combination treatment of SIN with DDP signi-ficantly induced apoptosis of HT-1080 cells.SIN up-regulated the protein levels of CTR1 and Bax,and down-regulated the protein levels of GST-πand Bcl-2(P<0.05).CONCLUSION:SIN synergistic induces apoptosis with DDP in human fi-brosarcoma HT-1080 cells by up-regulating the protein levels of CTR1 and Bax, and down-regulating the protein levels of GST-πand Bcl-2.

Abstract?AIM: To investigate mechanism of bradykinin ( BK) on inflammations of retinal pigment epithelium ( RPE) cells.?METHODS: ARPE -19 cells were cultured in vitro, stimulated by 100nM BK for 24h. Cell morphology changes were observed by microscope, and BK receptor localization was detected through cell immunofluorescence. Changes of Ca2+in BK and BR antagonist stimuli were detected by laser scanning confocal microscopy.The expressions of COX-1, COX-2, eNOS and iNOS protein in control group and BK group were detected by Western Blot.?RESULTS: After the stimulation of BK, there was no significant changes of ARPE-19 cells in morphology.Kinin B1 receptors ( B1R ) and B2 receptors ( B2R ) could be detected in ARPE-19 cells.Compared with control group, Ca2+concentrations significantly increased in BK group; in B1R antagonist group and B2R antagonist group Ca2+concentrations increased less than BK group; B1R and B2R antagonist group showed no obvious changes in Ca2+concentrations.Compared with control group, COX-2 and iNOS protein concentrations were significantly increased in BK group (P<0.001).?CONCLUSION:BK induces the increasing expression of COX-2 and iNOS in the cultured ARPE cells through binding with either B1R or B2R.

The study was aimed to investigate the effects of protein kinase C (PKC) on standard type CD44 expression and subcellular distribution in human erythrocytes. PKC activity was detected by the incorporation of [gamma-(32)P]-ATP into exogenous substrate, phosphorylation of CD44 was determined by autoradiograph, distribution of CD44 was observed by indirect immunofluorescence, and expression of CD44 was analyzed by flow cytometry. The results showed that PKC activity reached the maximal level at 30 minutes after treatment with phorbol-myristate-acetate (PMA), and the peak of CD44 phosphorylation and CD44 expression appeared at the same time, which all increased significantly as compared with control group (p < 0.001). PKC activation resulted in CD44 aggregation on membrane and colocalization of PKC and CD44. Calphostin C could inhibit the above reaction resulted from PKC activation. It is concluded that PKC activation can up-regulate CD44 expression by phosphorylation, and result in the coherent migration and colocalization of CD44 and PKC in human erythrocytes.

OBJECTIVETo evaluate the practicability and validity of transcranial magnetic motor evoked potential monitoring (TMS-MEP) during spinal surgery.

METHODSFrom February 2001 to June 2004, 37 patients undergoing spinal surgery were involved, anaesthesia was maintained with volatile anesthetics in 11 operations and etomidate in 26. Analgesia was provided with fentanyl, and non-depolarizing muscle relaxant was given intermittently. MEPs elicited with transcranial magnetic stimulations were recorded from tibialis anterior muscles, simultaneously bispectral index (BIS) and train-of-four stimulation (TOF) were used to monitor the anesthesia depth and neuromuscular blockade respectively. The variety of MEP and its effect on surgical operation at different anesthesia depth and muscular relaxation were observed, and the muscle strength of the patients before and after operation were compared.

RESULTSThe 11 cases anesthetized with isoflurane or enflurane gave no response to TMS, the other 26 cases in which anaesthesia was maintained with etomidate and fentanyl gave satisfactory TMS-MEPs, but with significantly attenuated amplitudes and prolonged latencies (P < 0.05). Intraoperative MEP showed a grossly unchanged waveform, and its amplitude and latency had little fluctuation when anaesthesia and neuromuscular blockade maintained stable. When T(1) value of TOF at 40% - 60%, a steady MEP could be acquired and the muscular contraction after TMS should not interfere the operation.Seven of 26 cases had a MEP amplitude drop up to 50% or more during the operation, the surgical team was notified to avoid further spinal injury, at last only 1 case had a worsen muscle power after operation.

CONCLUSIONSMyogenic TMS-MEP is a valid and practicable technique for intraoperative monitoring, and the etomidate + fentanyl technique is adequate for its anesthesia. BIS and TOF monitoring are helpful to maintain the steadiness of the anesthesia and MEPs, which is very important for monitoring the changes of the MEPs.
