ve To evaluate the effects of desflurane and sevoflurane on postoperative cognitive function in the elderly to see if there is any difference. Methods Seventy ASA Ⅰ-Ⅱ patients agedl≥65yr undergoing total knee or hip replacement were randomly assigned to one of the two anesthetic groups of thirty-five patients each:desflurane group and sevoflurane group. All patients were premedicated with midazolam 1 mg iv. Anesthesia was induced with fentanyl 1.0-1.5?g?kg-1, propofol 1.0-2.0 mg?kg-1 and succinylcholine 1 mg?kg-1 and maintained with either 2%-4% desflurane or 1.0%-1.5% sevoflurane combined with N2 O in O2 (1:1) and intermittent iv boluses of vecuronium. MAP, HR, ECG, SpO2, PETCO2 and end-tidal concentration of desflurane or sevoflurane were monitored continuously during operation. After tracheal intubation the patients were mechanically ventilated and PETCO2 was maintained at 30-40 mm Hg. The Mini-Mental State (MMS) test was used to assess cognitive function before and at 1, 3, 6 and 24h after surgery. Results Compared with the baseline values the MMS scores decreased significantly at 1h after operation in both groups. However the MMS scores returned to preoperative baseline levels within 6h after surgery in both groups. There were no significant differences in MMS scores between the two groups before and after operation. At 1h after operation 51% of the patients in desflurane and 57% in sevoflurane group experienced cognitive impairment. But at 3h after surgery the percentage of the patients with cognitive dysfunction decreased to 11% in desflurane group and 9% in sevoflurane group. Conclusions In the elderly the postoperative cognitive dysfunction is temporary lasting only a few hours and the effects of desflurane and sevoflurane are similar.

OBJECTIVE:To provide reference for promoting clinical rational application of Xueshuantong for injection(lyophi-lized). METHODS:By hospital centralized monitoring method,all medical records were retrieved from Hospital Information Sys-tem of our hospital,who received Xushuantong for injection(lyophilized)from Aug. 7 to Oct. 6 in 2015;general information of patients'drug information,drug utilization and the occurrence of ADR were traced and recorded by clinical pharmacists to evaluate the rationality of clinical utilization of Xushuantong for injection(lyophilized). RESULTS:Totally of 1014 medical records were included in the study. Xueshuantong for injection(lyophilized)was mainly used for fracture,cerebral infarction,coronary disease, cataract and other disease. 22 clinical departments as orthopedics department,neurology department,cardiology department and ophthalmology department were involved,accounting for 56.41% of total. For the patients receiving Xushuantong for injection(ly-ophilized),the average age was 63.12 years,the average course was 11 days and dose was 100-500 mg/time. They were given medicine intravenously once a day,and 0.9% Sodium chloride injection was used as solvent (93.29%). There were 10 kinds of drugs for drug combination averagely. The incidence of ADR was 5.92‰,and all ADR resulted from same batch of drugs (No. 15040211);ADR mainly manifested as erythra,erythema,pruritus,chills,etc. In terms of irrational drug use,the incidence of overlong treatment course was 17.85%;that of inadequate solvent dose was 13.71%;that of fast dripping rate was 7.59%;that of unsuitable solvent selection was 0.69%;that of drug use with no indication was 0.39%. CONCLUSIONS:Xueshuantong for injec-tion(lyophilized)is widely used in middle-aged and elderly in the clinic. There are many varieties and irrational drug use. The oc-currence of ADR is properly related to age,treatment course,solvent,dripping speed,product quality and other factors. Clinical pharmacists are required to monitor drug use,promote the rationality of drug use and reduce the occurrence of ADR.

Objective:To understand the laboratory characteristics for the diagnosis of immunoglobulin G4-related disease (IgG4-RD).Methods:The clinical data of 28 patients with IgG4-RD and renal damage (IgG4-RKD) diagnosed in our hospital from January 2017 to May 2019 were retrospectively analyzed. The correlation between serum IgG4 concentration and clinical features as well laboratory test results was analyzed. The 28 patients were divided into two groups: high serum IgG4 concentration group and normal serum IgG4 concentration group. The serum creatinine value, erythrocyte sedimentation rate, IgG concentration, IgA concentration, complement C3, C4 concentration, peripheral blood eosinophils, hemoglobin, IgG4/IgG and other related parameters were compared between the two groups. SPSS 20.0 statistical software was used for analysis. The two groups of measurement parameters were compared between groups by independent sample t test, non-normal measurement parameters were compared between groups by Mann-Whitney U test analysis, and the correlation between patients' IgG4 and each detection parameter was analyzed by Spearman correlation analysis. Results:Among the 28 patients, 17 were male and 11 were female, with an average age of (62±14) years. The serum IgG4 concentration increased in 75% of the patients ( n=21), with an average value of 3.01(1.41, 7.52) g/L, the serum IgG concentration increased in 64.3% of patients ( n=18), with an average value of 18.91 (12.88, 24.88) g/L, and the complement C3 decreased in 50% of the patients ( n=14), with an average value of(0.77±0.28) g/L. IgG4 was positively correlated with IgG ( r=0.422, P=0.025), IgG4/IgG ( r=0.951, P<0.01), ESR ( r=0.543, P<0.01) and peripheral blood eosinophils ( r=0.487, P<0.01), but negatively correlated with complement C3 ( r=-0.431, P=0.022) and C4 ( r=-0.504, P<0.01) levels. There were significant differences in IgG ( Z=-2.255, P=0.023), IgG4/IgG ( Z=-3.793, P<0.01), C3 ( t=7.380, P<0.01) and ESR ( t=-2.195, P=0.037) between the elevated IgG4 group and the normal group. Conclusion:Serological characteristics of IgG4-RKD combined with clinical manifestations may be able to diagnose IgG4-RKD in early stage.

Objective To compare the effect of laminar flow bed in the prevention of hospital infections in patients with leukemia after chemotherapy. Method The Meta-analyses were done on Meta RevMan5.0 by retrieving the domestic databases from January 1999 to January 2014 to look into and compare the hospital infections in leukemic patients using laminar flow beds and common beds, including of the rate of hospital infection, duration of fever, days for antibiotic use, hospital stay. Results A total of 16 papers were included. The Meta analyses showed that the rate of hospital infection in the wards with laminar flow beds was significantly lower than that in the wards with common beds (RR=0.54,95%CI (0.47, 0.62), P<0.01). The fever duration, time for antibiotics use and hospital stay in patients in the wards with laminar flow beds were all significantly shorter than those in the patients in the wards with common beds [WMD=-3.64, 95%CI (-4.83,-2.46);WMD=-4.13, 95%CI (-5.95,-2.32)];WMD=-5.36, 95%CI (-7.52,-3.20);P<0.01,respectively)]. Conclusion Laminar flow beds are effective in preventing hospital infections among acute leukemic patients having undergone chemotherapy.
