Objective A 23-year-old female patient who had a past history of sexual - precocity and fracture developed hyperhyroidism 8 months ago. Radiological examination revealed enlargement of sella turcica and a adrenal gland nodule. The patient was diagnosed to have McCune -Albright syndrome and scheduled for resection of left subtotal adrenalectomy under general anesthesia. The patient was taking (1) thiamazole 5 mg t. i. d. and propranolol 10 mg q. d. for hyperthyroidism; (2) adalat 10 mg t. i. d. and potassium citrate 20 ml t. i. d. for Cushing syndrome and (3) calcium tablets for osteoporosis. Anesthesia was induced with intravenous midazolam 1 mg, fentanyl 50 ?g and vecuronium 1 mg followed by propofol 150 mg and succinyl choline 100 mg. The patient was intubated and mechanically ventilated (VT = 500 ml, RR =10 bpm, I: E = 1 :2) . PET CO2 was maintained between 35 - 45 mm Hg. Anesthesia was maintained with inhalation of isoflurane and N2O - O2 (1:2) and intermittent i.v. boluses of fentanyl and vecuronium. The BP was increased to 180/110 mm Hg after induction of anesthesia. Urapidil 10 mg was given intermittently i.v. During the exploration of adrenal gland BP was again increased to 200/140 mm Hg. Nitroglycerin was infused i.v. and BP was decreased to 120-130/80-90 mm Hg and was kept at this level till the end of operation. Hydrocortisone succinate 100 mg was infused i.v. slowly after operation. The operation went smoothly. The patient was extubated and the postoperative course was uneventful.

Objective To investigate the predictive values of the pulsatility index detected by transcranial Doppler (TCD) and serum neuron-specific enolase (NES) in patients achieved return of spontaneous circulation after cardiopulmonary resuscitation (CPR). Methods The patients with CPR restoration of spontaneous circulation who were still in coma were divided into survival group and death group. TCD monitoring and serum NSE detection were performed at 48 hours after CPR restoration of spontaneous circulation. Receiver operating characteristic (ROC) curves were used to evaluate the predictive values of the pulsatility index detected by TCD and serum NES in patients after successful CPR. Results Seventy patients were collected, 32 patients (19 males and 13 females) in the survival group, age 54. 63 ± 13. 28 years; 38 patients (22 males and 16 females) in the death group, age 58. 00 ± 13. 15 years. There were no significant differences in age and gender between the survival and death groups. The pulsatility index was 1. 217 + 0. 352 in the death group, and it was significantly higher than 0.841 +0. 163 in the survival group; the serum NSE content was 130. 968±59.634 ng/ml in the death group, and it was signiflcantly higher than 49. 465 ± 26. 864 ng/ml in the survival gronp (P<0. 01). When the pulsatility index was used to predict the death of patients, the ROC area under the curve was 0. 794 (P=0. 000,95% confidence interval [CI] O. 679-0. 908);when the cutoff value was 1. 110, the sensitivity was 68.4%, the specificity was 100%,positive predictive value was 100%, and negative predictive value was 72. 7%. When serum NSE level was used to predict the death of the patients, the ROC area under the curve was 0. 756 (P= 0. 000, 95% CI 0. 672-0. 885); when the cutoff value was 56. 502 ng/ml, the sensitivity was 80. 8%, the specificity was 65. 4%, positive predictive value was 82. 5%, and negative predictive value was 76. 6%. Conclusions The pulsatility index detected by TCD and serum NSE content can be used as predictors in patients achieved return of spontaneous circulation after CPR.

Objective:To investigate the effect of exogenous nitric oxide(NO) on the growth and proliferation of gastric cancer cell line SGC-7901. Methods:The inhibitory effects of NO donor sodium nitroprusside (SNP) and nitric oxide synthase (NOS) inhibitor N-nitro-L-arginine methylester(L-NAME) on the proliferation of SGC-7901 cells were analyzed by MTT assay. The changes of mRNA and protein expression of proliferating cell nuclear antigen(PCNA) and caspase-3 were examined by RT-PCR and Western blotting. The cell cycle was measured using flow cytometry. Results:Compared with control group, more cells in the SNP group were arrested at G_1 and G_0 phases (P<0.05) and fewer cells were at S phases (P<0.05). SNP decreased the speed of cell-cycle progression from G_0/G_1 phase into S phase. SNP inhibited the proliferation of SGC-7901 cells and reduced the mRNA and protein expressions of PCNA and caspase-3. NOS inhibitor L-NAME reversed the effects of SNP. Conclusion:NO inhibited cell growth and proliferation, but accelerated apoptosis of gastric cancer cells.
