Effects of assisted-electroacupuncture on recovery of fast tracking anesthesia in mPCNL / 中国针灸

<p><b>OBJECTIVE</b>To compare the effects on anesthesia recovery between assisted-electroacupuncture fast tracking anesthesia and simple fast tracking anesthesia in patients with minim ally invasive percutaneous nephrolithotomy (mPCNL).</p><p><b>METHODS</b>Eighty cases of mPCNL were selected and randomly divided into a treatment group and a control group. Fentanyl (1-2 microg/kg), sevoflurane (8%) and rocuronium (0.5 mg/kg) were applied to perform anesthesia induction in both groups, and endotracheal inhalation of sevoflurane and intravenous pump injection of remifentanil were adopted to main anesthesia status during the operation. 20 min before anesthesia induction, bilateral Neiguan (PC 6), Neimadian, Hegu (LI 4), Yangxi (LI 5), Zhongji (CV 3), Qichong (ST 30), Zuwuli (LR 10) were selected and punctured in the treatment group, and elecctroacupuncture was given after arrival of qi until 30 min after the wake-up from anesthesia and withdrawal of endotracheal tube. The dosage for anesthesia maintenance, recovery time of awareness, extubation time, incidences of nausea, vomiting and chill and irritation of urethral catheters were observed and recorded.</p><p><b>RESULTS</b>(1) The dosages of remifentanil and sevoflurane in the treatment group during the operation were obviously less than those in the control group [remifentanil: (5. 27 +/-1.23) micro g/kg h vs (7.35+/-1.70) micro g/kg . h; sevoflurane: (1.12+/-0.43) vol% vs (2.35+/-0.87) vol% , both P<0. 001]. (2) The recovery time of awareness and extubation time in the treatment group were significantly earlier than those in the control group [recovery time of awareness: (5.65 +/- 2.34) min vs (8. 87 +/- 6. 84) min, P<0. 01; extubation time : (7. 23+/-4. 35) min vs (10. 62+/-8. 16) min, P<0. 05]. (3) The incidences of nausea, vomiting and chill in the treatment group were significantly less than those in the control group (all P<0. 05). (4) The irritation of urethral catheters on urethra in the treatment group was significantly less than that in the control group (P<0. 001).</p><p><b>CONCLUSION</b>The assisted-electroacupuncture anesthesia could reduce the dosage of remifentanil and sevoflurane in mPCNL fast tracking anesthesia in urinary surgery, reduce the incidences of nausea, vomiting, chill and irritation of urethral catheters during recovery stage, and prompt recovery of mPCNL patients.</p>

Laparoscopic high ligation of spermatic vein in the treatment of critical varicocele / 中国基层医药

Objective To probe into the clinical curative effect of laparoscopic high ligation of spermatic vein in the treatment of critical varicocele.Methods The clinical data of the 26 eases of laparoscopic high ligation of apermatic vein in the treatment of critical varicocde were reviewed and analyzed in the last two years in this hospi- tal.Results All the 26 cases had been conducted smoothly with the operation time 25～50min,an average of(28?3)min.After 3～24 months being followed-up,all the symptoms and signs disappeared with no relapse and testicle a- trophy.Eight wives of the patients who had been operated on got pregnant.Conclusion With soon recovery and small wound,it was safe to adopt laparoscopic high ligation of spermatic vein in the treatment of critical varicocele, especially for critical two-sided varicocde.

Effect of phytohemagglutinin on proliferation and cytotoxicity of cytokine-induced killer cells / 中国实验血液学杂志

The purpose was to investigate the effect of phytohemagglutinin (PHA) on proliferation and cytotoxicity of cytokine-induced killer (CIK). Peripheral blood mononuclear cells (PBMNCs) from healthy donors were divided into two groups. Cells were resuspended and maintained in complete medium containing of 10% autologous plasma. CIK cells were cultured by traditional method in group one. The other group cells were added PHA to stimulate PBMNCs for 24 hours, then cultured like incubating CIK cells. Their cytotoxicity to different target cells was evaluated by (51)Cr release assay. The results showed that the proliferation multiples of CIK and PHA-CIK cells were both high, however, the latter was much higher than CIK with significance (P < 0.05). Cells in each group cells showed high cytotoxicity. At the same high effector/target ratio PHA-CIK cells cytotoxicity was stronger than CIK cells when targets were K562 cells or acute leukemia cells (P < 0.05). In conclusion, PHA-CIK cells exhibit stronger proliferation and cytotoxicity than CIK cells, and the result provides an experimental basis for biotherapy.

Cytotoxic effects of arsenic trioxide in combination with chemotherapeutic drugs on acute non-promyelocytic leukemia cells / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To provide experimental basis for extending the indications of arsenic trioxide (As(2)O(3)) in clinical application.</p><p><b>METHODS</b>MTT assay was used to detect the cytotoxicity of As(2)O(3) in combination with daunorubicin (DNR), cytosine arabinoside (Ara-C), harringtonine (H) and vincristine (VCR) respectively on leukemic cells from 23 newly diagnosed cases with acute non-promyelocytic leukemia (ANPL) and 16 cases of relapsed, refractory ANPL.</p><p><b>RESULTS</b>(1) As(2)O(3) inhibited the growth of leukemic cells from both newly diagnosed or relapsed and refractory ANPL patients, and there was no statistical difference in cytotoxicity of the patients in the two groups [(12.6 +/-7.7 compared with 10.1 +/-6.2)%, P<0.05]. (2) There was no correlation between the cytotoxicities of As(2)O(3) and Ara-C, H or VCR (P<0.05), but a linear correlation between As(2)O(3)and DNR was found (r=0.432, P<0.05).(3) Additivity and synergism of the cytotoxicity was found in most of the ANPL patients when As(2)O(3) was combined with the four chemotherapy drugs and the combination of As(2)O(3) with DNR or VCR enhanced the cytotoxicity significantly (P<0.05).</p><p><b>CONCLUSION</b>The results indicate that As(2)O(3) might be used in treatment of newly diagnosed or relapsed and refractory ANPL patients;and the combination of As(2)O(3) with DNR or VCR may enhance its therapeutic efficacy.</p>
