Objective To compare the accuracy of BIS and skin conductance (SC) for assessment of the depth of sedation induced by target-controlled infusion (TCI) of propofol. Methods Thirty ASA Ⅰ orⅡpatients aged 21-56 yr weighing 52-85 kg undergoing orthopedic operation on the lower limb under epidural anesthesia were enrolled in this study.After the onset of epidural anesthesia, TCI of propofol was started at an initial target plasma concentration (Cp) of 0.8 μg/ml. Th Cp was increased by 0.5-0.8 μg/ml every 3 min until OAA/S score=1. OAA/S score, BIS and SC values were recorded, SC change value (△SC) was calculated. Spearman rank-order correlation, receiver operating characteristic curve (area under curve AUC was calculated) and logistic regression were used to analyze the relationship of OAA/S score to BIS and △SC.Results BIS and △SC were significantly correlated with OAA/S scores (r were 0.920 and-0.859 respectively). The AUC of △SC (0.919, 0.946) was significantly better correlated with OAA/S score (5→4, 4→3) than that of BIS (0.761, 0.507), while BIS was better correlated (0.781, 0.959) with OAA/S score (3→2, 2→1) than ASC (0.577, 0.630). Logistic regression correctly predicted loss of consciousness. The accuracy of prediction was 93% for BIS and 82% for △SC. Conclusion The accuracy of SC for assessment of the depth of sedation induced by propofol TCI ishigher than that of BIS before loss of consciousness,while lower than that of BIS after loss of consciousness. BIS is more accurate in monitoring the loss of consciousness.

Objective To investigate the effect of rocuronium on spectral entropy during induction of general anesthesia in patients of Uygur nstionality. Methods Forty ASA Ⅰ or Ⅱ patients (Uygur nationality) of both sexes, aged 20-50 yr, weighing 45-70 kg, undergoing elective surgery under general anesthesia, were divided into 2 groups ( n = 20 each): normal saline (NS) group and rocuronium group (group R). Anesthesia was induced with target-controlled infusion of propofol. The initial target plasma concentration wan net at 2 μg/ml. The concentration wan then increased by 0.5 μg/ml every 4 min until response entropy (RE) was decreased to 45 and maintained for 4 min. When the plasma concentration was equal to the effect-site concentration, iv rocuronium 0.6 mg/kg was injected in group R, while group NS received the equal volume of NS instead. Fentanyl 3 μg/kg was injected intravenously at 3 min after recuronium administration. The patients were tracheal intubated and mechanically ventilated. State entropy (SE) and RE were recorded immediately before induction (baseline, To), before rocuronium administration (T1), 2 main after rocuronium administration (T2) and at 0, 1, 2 and 3 min after intubation (T3-6). The difference between RE and SE wan calculated. Results The RE value at T3 and T4 and the difference between RE and SE at T2.5 were significantly lower in group R than in group NS ( P < 0.05). Conclusion Rocuronium can decrease the RE value and degree of increase in the difference between RE and SE during induction of general anesthesia in patients of Uygur nationality, which may affect the accuracy of spectral entropy in monitoring the depth of anesthesia.

OBJECTIVE:
To study the early gene diagnosis of hereditary hemorrhagic telangiectasia (HHT) induced severe nosebleed.
METHOD:
Clinical features of 23 family members in two HHT pedigrees were examined. Genomic DNA was extracted from peripheral blood samples. PCR amplification was conducted to screen ENG and ACVRL-1 genes with their specific primers. Direct sequencing was performed to detect the mutation. Mutation analysis was carried out to evaluate its significance.
RESULT:
A heterozygous c. 263A > G mutation was identified in exon 3 of ACVRL-1 in 6 out of 11 members in NMG-1 pedigree. In GD-2 pedigree, 5 of 11 members carried c. 199C > G mutation. Mutation detection rate was 100% in subjects with nosebleed history and 25% in family members without epistaxis.
CONCLUSION
Gene diagnosis characterized by high sensitivity and specificity is of great practi-cal significance and early genetic screening should be a clinical routine test for HHT induced severe nosebleed.

OBJECTIVE To analyze existing problems of pharmacoeconomic evaluation research in China and to improve the standardization and scientificity of research, so as to provide more high-quality evidence for government decision-making. METHODS Retrieved from CNKI, Wanfang database, VIP, PubMed, Web of Science from 2018 to 2022, the literature related to pharmacoeconomic evaluation in China was collected; Excel 2016 software was used to extract the key information of the included literature which met inclusion criteria. The Quality of Health Economic Studies (QHES) scale was used to evaluate the quality of the included literature. RESULTS A total of 113 pieces of literature were included in this study, involving 85 pieces of Chinese literature and 28 pieces of English literature. The overall score of QHES included literature was 65.7, of which the average score of Chinese literature was 62.0 and English literature was 76.9. The median quality scores for the literature in 2018, 2019, 2020, 2021 and 2022 were 62.0, 70.5, 59.3, 71.0, and 73.0, respectively. Of these, 65 pieces of literature reported the research perspective; 36 reported the discount rate indistinctly; 25 provided unclear definitions of thresholds; and 53 used two sensitivity analysis methods. Among different items of the QHES scale, item 2 (research perspective), item 8 (time range and discount rate), item 14 (potential bias) and item 16 (sources of funding) had low percentage of scores. CONCLUSIONS From 2018 to 2022, pharmacoeconomic evaluation literature published by Chinese academics has generally shown a fluctuating upward trend in terms of quality, but there is still some room for improvement. The main problems in current pharmacoeconomics research in China include unclear understanding of the research perspective, single measurement of cost and health outcomes, unreasonable design of time horizon, indistinct description of the threshold or discount rate, and lack of sensitivity analysis.

Objective To investigate the effect of exosomes derived from Echinococcus multilocularis on macrophage polarization after treatment for different durations and concentrations. Methods A total of 60 BALB/c mice were used for modeling, among which 4 mice were selected to observe the growth of abdominal lesions on 7.0T MRI. The mice for modeling were dissected, and the protoscoleces was taken from the abdominal lesion and cultured in vitro ; ultracentrifugation was used to extract the exosomes from the supernatant, and transmission electron microscopy and Western blotting were used for the characterization of exosomes. The macrophages without exosome treatment were established as control group, and the macrophages co-cultured with different concentrations of exosomes derived from Echinococcus multilocularis were established as experimental group (10 μg/mL group and 50 μg/mL group) and were cultured for 48 and 72 hours. The morphological changes of macrophages were observed under a microscope, and flow cytometry and ELISA were used to observe polarization state. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t -test was used for further comparison between two groups. Results The results of 7.0T MRI showed the formation of diffuse lesions with different sizes in the abdominal cavity of mice, and the exosomes derived from Echinococcus multilocularis were approximately 100 nm in diameter and were cup-shaped or saucer-shaped, with the positive expression of the surface markers CD9, TSG101, and CD63. After co-culture, most of the cells in the experimental group were elongated with an irregular and polygonal shape. Flow cytometry showed that after 48 hours of co-culture, the positive rates of CD16/32, CD206, and CD369 in the control group were 99.53%±0.06%, 90.27%±0.21%, and 2.40%±0.20%, respectively; compared with the control group, except that the 10 μg/mL exosome group had a significant reduction in the positive rate of CD369 (0.80%±0.00%) ( P < 0.05), all the other groups had a significant increase in the positive rates of CD16/32, CD206, and CD369 (all P < 0.000 1); after 72 hours of co-culture, the positive rates of CD16/32, CD206, and CD369 in the control group were 99.67%±0.06%, 85.47%±0.55%, and 6.60%±0.20%, respectively, and compared with the control group, the experimental group had significant increases in the positive rates of CD16/32, CD206, and CD369 (all P < 0.05). ELISA showed that after 48 hours of co-culture, the levels of IL-6 and TNFα in the control group were 58.53±15.52 pg/mL and 320.70±5.30 pg/mL, respectively, and when the exosome concentration was 50 μg/mL, the level of IL-6 in the experimental group was 98.81±15.55 pg/mL, which was higher than that in the control group ( P < 0.05); after 72 hours of co-culture, the levels of IL-6 and TNFα in the control group were 76.22±9.68 pg/mL and 323.90±87.37 pg/mL, respectively, and when the exosome concentration was 10 μg/mL, the level of TNFα was 164.20±14.17 pg/mL, which was significantly lower than that in the control group ( P < 0.05); when the exosome concentration was 50 μg/mL, the level of IL-6 was 99.52±8.35 pg/mL, which was significantly higher than that in the control group ( P < 0.05). Conclusion Exosomes derived from Echinococcus multilocularis can regulate macrophage polarization and induce M2-like polarization of macrophages after co-culture at a concentration of 10 μg /mL for 72 hours, and further studies are needed to clarify the specific method.
