Objective To investigate the effects of goal‐directed volume therapy (GDVT )on the intracranial pressure(ICP) and the balance of cerebral oxygen consumption and supply in selective neurosurgery. Methods Twenty‐four patients sched‐uled for intracranial tumor resection were randomly divided into 2 groups:conventional fluid management group (group C ,n=12) and GDVT group(group G ,n=12). Patients in group C received introperative fluid transfusion according to classical fluid management strategies while those in group G received GDT according to stroke volume variation (SVV) ,guided by Flotrac‐Vigileo system.Mean arterial pressure(MAP) ,heart rate(HR) ,cardiac index(CI) ,ICP ,SVV and jugular bulb oxygen saturation (SjvO2 )were recorded before the anesthesia induction(T1 ) ,at the moment of intubation(T2 ) ,at the moment of opening the hard meninges(T3),1hafteropeningthehardmeninges(T4),andattheendofthesurgery(T5).Thecerebraloxygenextractionra‐tio(CERO2 )was calculated. The duration of surgery ,crystalloid volume ,colloid volume ,blood transfusion volume ,urinary output and bleeding volume were recorded as well.Results The colloid transfusion volume ,the total fluid transfusion volume and uri‐nary output were significantly increased in group G when compared with those in group C (P<0.05).MAP ,CI ,and SjvO2 were much higher and CERO2 were much lower at T4 and T5 in group G than in group C(P<0.05). There was no significant differ‐ence in the ICP at each time point between groups G and C (P>0.05).Conclusion Goal‐directed fluid therapy optimizes the cardiac preload without increasing the ICP in selective neurosurgery ,and it also improves the balance of cerebral oxygen con‐sumption and supply.

OBJECTIVETo observe the clinical effect of Huikangling Tablet (HT, extracted from Scabrous Patrinia root) on peripheral blood micrometastasis of differentiated thyroid carcinoma (DTC) patients.
METHODSTotally 87 DTC patients with positive micrometastasis were randomly assigned to the treatment group (45 cases) and the control group (42 cases). DTC endocrine inhibition treatment standards were executed in all patients. They all took levothyroxine sodium (50 microg/tablet, from low dose, 25 microg each time, once per day, 0.5 h before breakfast), and its dosage was gradually added one week later. The dosage was adjusted according to tested results of TSH combined recurrence risk stratification and endocrine suppression induced adverse reactions risk stratification. Patients in the treatment group took HT (0.4 g per tablet, 3 tablets each time, three times per day for a total of 12 weeks) combined TSH suppression therapy, while those in the control group only received TSH suppression therapy. Peripheral micrometastatic cytokeratin 19 (CK19) and polymorphic epithelial mucin1 (MUC1) were detected by FCM at week 4 and 12. Meanwhile, distant metastasis and adverse reactions were observed.
RESULTSAfter 4-week treatment positive micrometastasis was shown in 18 cases (40%) of the treatment group and 29 cases (69%) in the control group with statistical difference (chi2 = 5.68, P < 0.05). After 12-week treatment positive micrometastasis was shown in 7 cases (15.6%) of the treatment group and 17 cases (44.7%) in the control group with statistical difference (chi2 = 8.49, P < 0.01). Pulmonary metastasis occurred in 2 cases and bone metastasis in 1 case of the control group at follow-ups. Cervical lymph node metastasis without accompanied recurrence of thyroid cancer occurred in one case of the treatment group. No obvious liver or renal abnormalities occurred.
CONCLUSIONHT inhibited peripheral blood micrometastasis of DTC patients and its mechanism needed to be further studied.
