ObjectiveTo compare the clinical efficacy and safety of anesthesia induction between inhalation of sevoflurane and intravenous injection of propofol for laryngeal mask airway (LMA) insertion in elderly patients.Methods40,ASA physical grade Ⅰ ～ Ⅱ patients scheduled to receive elective total knee arthroplasty were allocated to 2 groups at random. Patients in group one( G1 ) received intravenous induction of propofol infusion by a targetcontrolled infusion system which was set at the effect-site concentration of 4.0μg/ml,while patients in group two(G2)received inhalational induction with sevoflurane using vital capacity manoeuver at the target of end-expiratory concentration of 3.0％. We observed the whole procedure of anesthesia induction and LMA insertion, while recording the changes in hemodynamic state and occurrence of adverse events. ResultsMore than 85％ patients achieved LMA insertion at first attempt using either induction manoeuver. Although consciousness loss time in G1 was 39. ls longer than G2, there was no difference in anesthesia induction time for LMA insertion between these two groups. Contrary to a significant decrease in MAP following induction for patients in G1, there appeared hemodynamically stable in patients of G2,while apnea also significantly seldom occurred in G2 as compared to G1 (20％ vs 85％ ,P ＜0. 05).ConclusionAs compared to intrvenous induction with propofol, inhalation induction with sevoflurane provided a valuable alternative for LMA insertion in adults.

During 131Ⅰ therapy or the natural course of DTC,2％ to 5％ of them will gradually no longer be sensitive to 131Ⅰ therapy and lead to radioactive iodine-refractory DTC (RAIR-DTC).Recent studies found that alterations of critical molecular targets in main signal transduction pathways could decrease the iodine-trapping function of thyroid carcinoma,such as BRAFV600E mutation,followed by negative 131 Ⅰ-whole body scan (WBS) and discounted efficacy.This article reviews novel diagnostic and therapeutic modalities for RAIR-DTC.

Objective To study the epidemiological characteristics of the acute toxicosis cases in a general hospital of a metropolis. Methods The prospective study was performed from Jan. 1st, 2005 to Dec. 31st, 2006 in acute toxicosis patients admitted during that period. The data analyzed included sex, age, occupation, onset time, poisoning cause, variety of poisons, way of poisoning, emergency diagnosis, emergency treatment, etc. Results There were 315 poisoning patients treated during the study period, accounting for 2.33‰ of the total patients visiting in the emergency department. Among these poisoning patients, the sex ratio (males vs females) was 1∶0.84. The age of most of the patients ranged from 20 to 29 (35.9%) years old. Alcohol was the major cause of poisoning (38.4%), followed in order by poisoning due to drugs (20.6%), food poisoning (18.1%), chemical poisoning (10.2%) and pesticide poisoning (5.7%). There was predominant time of the occurrence of poisoning in a year, but it was more frequent in January, February, June, July, November and December. 85.1% of patients were poisoned by oral route. The occupation of patients was mainly technical personnel (21.0%), followed in order by farmers and the laborers, self-employed businessmen, persons taking care of household chores and the unemployed, etc. 98.1% of patients survived in the hospital. Mortality rate was 1.9%. Conclusions Young persons and technical personnel constitute the high-risk group of patients with poisoning. The main poisons were alcohol, drugs, food and other chemical poisons. The main route of poison intake was the digestive tract. There is no obvious seasonal regularity.

Objective To set up the quality control standard for Leaf of Chinese Holly; To provide basis for the utilization and development of Leaf of Chinese Holly.Methods Ten batches of Leaf of Chinese Holly samples from different habitats were collected, and the properties were described. The crosscutting and powder of leaf was under microscopic identification. Chlorogenic acid was set as reference substance to conduct thin-layer identification. Moisture, total ash, and acid-insoluble ash of the 10 batches were detected. HPLC was used to detect chlorogenic acid in Leaf of Chinese Holly.Results The properties and microscopic identification were described. Thin-layer chromatography method for chlorogenic acid in Leaf of Chinese Holly was formulated. Check items temporarily required that the moisture in Leaf of Chinese Holly should be less than 13%, total ash less than 13%, and acid-insoluble ash less than 5%. Content determination method for chlorogenic acid in Leaf of Chinese Holly was confirmed. It temporarily required that the content of chlorogenic acid should be more than 0.60%.Conclusion The established method can be used for the formulation of quality control of Leaf of Chinese Holly.

Background and purpose:This study aimed to investigate the relationship between lymph node metastatic rate (LR) and response to radioiodine therapy in patients with papillary thyroid carcinoma (PTC).Methods:A total number of 143 PTC patients after radioiodine therapy were included and classified into 4 groups [Ⅰ(0%-10%),Ⅱ(>10%-25%),Ⅲ(>25%-50%),Ⅳ(>50%)] according to the lymph node metastatic rate, and the responses to initial radioiodine therapy after a median follow-up period of 20.7 months were evaluated. They were classiifed into 4 groups [excellent response (ER), indeterminate response (IDR), biochemical incomplete response (BIR), and struc-tural incomplete response (SIR)] according to the guideline proposed by 2015 American Thyroid Association. One-Way analysis of variance,χ2 test and Kruskal-Wallis test were used to evaluate the differences in basic clinicopathological features and clinical responses among the 4 groups. The ROC curve was analyzed to evaluate the clinical value of lymph node metastatic rate for predicting ER and optimal cut-off point.Results:There were no signiifcant differences in gender and T-stage among 4 groups (P>0.05). However,Ⅰ group was signiifcantly older than the other 3 groups (P=0.001). With the increase of lymph node metastatic rate, the number of ER cases decreased, while cases of BIR and SIR generally increased. Compared with the other 3 groups, less cases of ER (27.8%), while more BIR (27.8%) or SIR (11.1%) were observed in groupⅣ (H=18.816,P=0.000). Cut-off value of lymph node involved rate was 52.27%, with a better speciifcity of predicting ER. Area under the ROC curve was 0.668.Conclusion:The higher lymph node metastatic rate in patients with PTC, the worse clinical outcome it could be. A cut-off value of lymph node metastatic rate 52.27% is a speciifc independent predictor for the clinical outcome in PTC patients treated with radioiodine therapy.

Objective To investigate the apoptosis of renal tubule epithelium after cardiopulmonary resuscitation(CPR)in rats and its possible mechanism.Methods Cardiac arrest was induced by asphyxiation(succinylcholine)and ice-cold 0.5 mol/l KCL in rats,and resuscitation started at 5 minutes after arrest.Forty-eight male SD rats were randomly divided into 6 groups:sham(control group);after cardiopulmonary resuscitation rats were allowed to reperfuse spontaneously for 3 hours,6 hours,12 hours,24 hours and 48 hours(n=8,per group).The apoptosis of renal tubule epithelium was assessed by TUNEL.Fas and Bcl-2 protein expression were observed using immunocytochemistry in every group.Results The apoptosis of renal tubule epithelium was singnificantly increased at 3 hours after resuscitation and peaked at 24 hours(P

Objective To evaluate the impact of low-dose 131I therapy and high-dose 131I therapy on the clinical outcome in PTC patients coexisting with Hashimoto's thyroiditis (HT).Methods A total of 140 non-distant metastatic PTC patients (16 males,124 females,age range:16-66 years) from July 2010 to December 2014 were enrolled in this retrospective study.Patients concurrent with HT (n=84,group A) were divided into low-dose group (1 110 MBq,n=56,group A1) and high-dose group (5 550 MBq,n=28,group A2) according to 131I ablation dose.Patients without HT (n =56) were enrolled as control group (group B),and received 1 110 MBq of 131I.The thyroid remnant ablation outcome was evaluated according to 131I diagnostic whole-body scan (Dx-WBS),neck ultrasonography (US),serum Tg and TgAb level 6-8 months after 131I ablation therapy.The successful ablation rates were compared by x2 test.Kruskal-Wallis rank sum test was also used.Results There were no significant differences among the 3 groups in terms of both clinicopathological features and postoperative remnant thyroid (H:0.203-2.944,x2:0.271-0.970,all P＞0.05).When negative Dx-WBS and US were deemed as successful ablation criterion,complete ablation rate was found significantly more in group B (94.6％,53/56) than that in group A1 (82.1％,46/56;x2=4.264,P＜0.05),but no significant difference was found between group A2 (85.7％,24/28) and group A1 (x2 =0.318,P＞0.05).When combining negative sTg (sTg＜1 μg/L,TgAb＜46 kU/L) with the above 2 criterions to assess remnant ablation outcome,group B also had a higher successful rate to achieve complete ablation (85.7％,48/56) compared with group A1 (75.6％,34/45),but without statistical significance (x2=2.978,P＞0.05),and no difference was observed between group A2 (12/15) and group A1 (x2=1.320,P＞ 0.05).Conclusion Non-distant metastatic PTC patients coexisting with HT has undesirable 131I ablation outcome compared with those without HT,increasing 131I dose is unhelpful to enhance efficiency of remnant ablation for PTC patients with HT.
