Objective To study effect of general anesthesia combined with epidural anesthesia on analgesia and microcirculation in patients undergoing total hysterectomy. Methods 92 patients of total hysterectomy who received therapy were selected, according to random number table,those patients were divided into the observation group (n=42) and the control group (n=48),the observation group received general anesthesia combined with epidural anesthesia, the control group were only given general anesthesia.The operation condition, hemodynamics and stress response before anesthesia(T0), at tracheal intubation(T1), after pneumoperitoneum 10min(T2), after surgery(T3), at extubation(T4) were compared,and postoperative pain (VAS) score was compared. Results There was no significant difference in operation time and fluid volume between the two groups. In the control group,the levels of mean arterial pressure (MAP), heart rate (HR) at the time of T1, T2, T3 were significantly increased(P<0.05), the levels of MAP and HR at the time of T1,T2,T3 in the observation group were lower than the control group(P<0.05). The cortisol (Cor), epinephrine (E), norepinephrine (NE) at the time of T1,T2,T3,T4 in the observation group were lower than the control group(P<0.05). Two groups of patients in the postoperative 12h, 6h, the VAS scores in the resting state and cough state were higher than the postoperative 1h(P<0.05),but the scores in the observation group were lower than the control group(P<0.05). Conclusion General anesthesia combined with epidural anesthesia is well for total hysterectomy,which can maintain hemodynamic stability during surgery, relieve stress reaction, alleviate postoperative pain, it is worthy of application and promotion.

Objective: To investigate the appropriateness of desflurane anesthesia used in patients undergoing intracranial operations. Methods: Sixteen patients were scheduled for removal of supratentorial mass. A radial artery catheter and a subarachanoid catheter were placed respectively prior to induetion of anesthesia. MAP, cerebrospinal pressure (CSFP), PETCO2 and HR were monitored. Anesthesia was induced with intravenous midazolan, fentanyl, propofol and vecuronium. After endotracheal intubation, anesthesia was maintained by desfurane inhalation in a concentration of 6 % (1MAC) throughout the operation. MAP, CSFP and PETCO2 were recorded before and during induction, at 20min, 30min, 40min and 50min during desflurane inhalation. Results: Compared with the baseline data recorded before anesthesia, CSFP and MAP were decreased significantly during induction. The CSFP tended to increase at 20 min after inhalation of 6 % desflurane, but remained below the baseline till 50min. MAP was decreased following inhalation of 6 % desflurane and kept relatively stable thereafter. No significnt change in HR was noted. Conclusion:Under the condition of PETCO2 28-30mmHg, 1MAC desflurane anesthesia can be used safely without any increase in ICP in patients undergoing intracranial operations.

Objective To investigate the urodynamic measurements in later pregnant women with urinary incontinence. Methods According to the symptoms, a total of 63 volunteers in later pregnancy were divided into two groups including urinary incontinence group and no symptom group. Fourteen women who were married but not delivered were included in control group. Urodynamic study was performed on all women. Results The occurrence rate of urinary incontinence in later pregnancy was 26.98%. The valsalva leak point pressure only occurred on two pregnant women were 50 cmH2O and 67 cmH2O respectively. Compared with the no symptom group, the maximum urethral closure pressure[(83.69±42.55)mmHg vs(108.09±34.95)mmHg, P<0.05])and the functional urethral length [(30.45±8.42)mm vs (37.60±18.45)mm ,P<0.05]of urinary incontinence group were decreased obviously. Conclusions The main reason of urinary incontinence in pregnancy was that the maximum urethral closure pressure could not sufficiently increase to compensate for the progressive increase in bladder pressure during pregnancy and functional urethral length could not correspondingly increase along with the pregnancy.

AIM To study the effects of neferine on gastric car cinoma apoptosis induced by vincristine in vitro. METHODS Cytotoxicity assay was tested by MTT method. The influence of neferine to affect vincristine to induce gastric carcinoma apoptosis was detected by PI staining flow cytometry, AO/EB double fluorescence stain and terminal deoxynucleotidyl transferase mediated nick end labeling (TUNEL). RESULTS 2 5, 5,10 ?mol?L -1 neferine enhanced vincristine to inhibit the proliferation of SGC7901 cells; 10 ?mol?L -1 neferine enhanced vincristine (0 1, 0 5, 2, 4 mg?L -1 ) to induce SGC7901 cells apoptosis. CONCLUSIONS Neferine enhanced vincristine to induce gastric carcinoma cells apoptosis. It is inferred a kind of low poisonous and high effective chemosenstizers.

AIM: To investigate the effect of neferine (Nef) on human gastric carcinoma cell line with multidrug resistance (MDR). METHODS: The cytotoxic effect of vincristine (VCR) was evaluated by MTT assay. The cell apoptosis induced by VCR was determined by flow cytometry, and the expression of P-glycoprotein (P-gp) and multidrug-resistance-associated protein (MRP) in cells was examined by immunofluorescence flow cytometry. RESULTS: MTT assay showed that Nef at the concentration of 5 ?mol?L~(-1) to 10 ?mol?L~(-1) have no cytotoxicity to parent human gastric carcinoma cell line (SGC7901) and its VCR-resistant variant cell line (SGC7901/VCR). The IC_(50) value of VCR to SGC7901 cell line was 0.06 mg?L~(-1)and that of to SGC7901/VCR cell line was 2.32 mg?L~(-1), which indicated SGC7901/VCR cell line were 39 times more resistant to VCR in comparison with the parent SGC7901 cell line. After treatment with Nef at the concentrations of 2.5, 5 and 10 ?mol?L~(-1), the IC_(50) value of VCR to SGC7901/VCR cell line decreased to 0.34, 0.12 and 0.05 mg?L~(-1), respectively and those increased by 6.8-, 18.1- and 43.8- fold in the chemosensitivity, respectively. Flow cytometry showed that SGC7901/VCR cells were resistant to apoptosis induced by VCR. After 24 h treatment with Nef (2.5, 5 and 10 ?mol?L~(-1)) and VCR, the apoptosis of SGC7901/VCR cells increased, which indicated Nef could abolish resistance of SGC7901/VCR cells to VCR-induced apoptosis. Furthermore, the action of Nef was more potent than verapamil. The expression of P-glycoprotein and multidrug resistance associated protein was strongly positive in SGC7901/VCR cells, and the expression level of P-gp and MRP in SGC701/VCR cells was significantly down-regulated at 24 h after treatment with Nef (10 ?mol?L~(-1)). CONCLUSIONS: Nef can reverse MDR in multidrug-resistant human gastric carcinoma SGC7901/VCR cell line. Its mechanism might be associated with down-regulation of expression of P-gp and MRP in SGC7901/VCR cells.

Objective To measure and calculate the dose distribution (tissue absorbed dose) of mouth floor area while using 125I to treat sublingual gland carcinoma.Methods Phantom of head and neck was used to place the 125I radioactive seeds to simulate the sublingual gland carcinoma treatment.125I radioactive seeds of 29.6 and 25.9 MBq per seed were used as two groups,with 31 seeds in each group,and prescribed dose (peripheral matched dose) was 120 Gy.Thermoluminescence dosimetry (TLD) was used to measure the absorbed dose value in the simulated target and adjacent area.Gafchromic Eriochrome Black T (EBT) film was used to draw the dose distribution curve.Results Dose absorbed in the target area,target area center and the adjacent area one centimeter away from target reached 160 Gy,390-500 Gy,and 90-170 Gy,respectively.Dose of the skin ranged from 25 to 81 Gy,dose of mandible ranged from 7.9 to 67 Gy.No radiation cold spot was found.Conclusions 125I seeds could achieve an effective therapeutic dose distribution of the target area for sublingual gland carcinoma.Dose absorbed in the adjacent tissue is under safety limit.The radiation dose at mandible is lower,reducing the possibility of radiation damage to the bone.
