Objective:To investigate the effects of dexmedetomidine on vital signs during recovery from general anesthesia in gynecological patients undergoing general anesthesia surgery and analysis of risk factors for complications.Methods:A total of 80 gynecological patients undergoing general anesthesia surgery who received treatment in Lishui People's Hospital from March 2021 to March 2022 were included in this study. They were randomly divided into an observation group and a control group ( n = 40/group). All patients were subjected to general anesthesia. The observation group was infused with 0.5 μg/kg dexmedetomidine intravenously 15 minutes before induction of anesthesia and then infused with dexmedetomidine at a rate of 0.2 μg/kg per hour until 20-30 minutes before the end of the operation. The control group was identically given 0.9% normal saline. The recovery quality, vital signs before surgery and during recovery from general anesthesia (systolic blood pressure, diastolic blood pressure, heart rate, body temperature), and complications during recovery from general anesthesia were compared between the two groups. These patients were divided into a complication group and a non-complication group according to whether there were complications during recovery from general anesthesia. Univariate and multivariate Logistic regression analyses were performed to analyze the high-risk factors for complications occurring during recovery from general anesthesia in gynecological patients undergoing general anesthesia surgery. Results:The time to awaken, time to recover spontaneous respiration, and time to extubation in the observation group were significantly shorter than those in the control group ( t = 3.74, 2.97, 2.56, all P < 0.05). Systolic blood pressure, diastolic blood pressure, and heart rate measured during recovery from general anesthesia were significantly lower in the observation group compared with the control group ( t = 5.71, 4.53, 4.53, all P < 0.001). Body temperature ( t = 4.40, P < 0.001) and the incidence of complications ( χ2 = 5.69, P < 0.05) were significantly lower in the observation group compared with the control group. These patients were divided into complication ( n = 22) and non-complication ( n = 58) groups according to whether they had complications during recovery from general anesthesia. Univariate and multivariate logistic regression analyses showed that American Association of Anesthesiologists grade II, presence of underlying diseases, abnormal leukocyte count, and no use of dexmedetomidine were the risk factors for postoperative complications in gynecological patients undergoing general anesthesia surgery ( OR = 2.38, 2.86, 2.17, 3.60, all P < 0.05). Conclusion:Dexmedetomidine can improve awakening quality and vital signs and reduce complications during recovery from general anesthesia. American Association of Anesthesiologists grade, underlying disease, abnormal white blood cell count, and no use of dexmedetomidine are the risk factors for complications occurring during recovery from general anesthesia in gynecological patients undergoing general anesthesia surgery.

OBJECTIVE:To explore clinical efficacy and safety of Ulinastatin injection combined with Xingnaojing injec-tion in the treament of severe craniocerebral injury(CCI). METHODS:A total of 120 severe CCI patients selected from our hospital during Sept. 2014-Nov. 2015 were divided into ulinastatin group,Xingnaojing group and combination group according to therapy plan,with 40 cases in each group. Three groups were given routine treatment timely after admission. On the basis of routine treatment,Ulinastatin group additionally received Ulinastatin injection 200 000 U,ivgtt,bid;Xingnaojing group addi-tionally received Xingnaojing injection 20 mL,ivgtt,qd;combination group additionally received Ulinastatin injection com-bined with Xingnaojing injection,same usage as above(with 1 h intervals). Three groups received therapy for consecutive 14 d. Serum inflammatory factors(CRP,IL-1,IL-6,TNF-α),serologic indexes of craniocerebral injury [neuron specific enolase (NSE),myelin basic protein(MBP),S100B protein(S100B)] and GCS scores before and after treatment as well as GOS scores after treatment were all observed in 3 groups. The occurrence of ADR was recorded during treatment. RESULTS:Before treatment,there was no statistical significance in serum inflammatory factors,serologic indexes of craniocerebral injury or GCS scores among 3 groups(P>0.05). Compared to before treatment,inflammatory factors of 3 groups were decreased signifi-cantly after treatment,the ulinastatin group was significantly lower than the Xingnaojing group,combination group was signifi-cantly lower than two single drug groups,with statistical significance(P<0.05). Levels of serologic indexes of craniocerebral injury and GCS scores of 3 groups were improved significantly,and the combination group was significantly better than the two single drug groups,with statistical significance(P<0.05). There was no statistical significance between ulinastatin group and Xingnaojing group(P>0.05). Six months after treatment,GOS score of combination group(4.17±0.81)was significantly better than those of ulinastatin group(3.05±0.97)and Xing-naojing group(2.97 ± 0.89),with statistical significance (P<0.05);there was no statistical significance between ulinastatin group and Xingnaojing group(P>0.05). During treatment,the incidence of ADR in combination group(27.50%)was significantly lower than ulinastatin group(50.00%)and Xingnaojing group(42.50%),with statistical significance(P<0.05);there was no statistical significance between ulinastatin group and Xingnaojing group(P>0.05). CONCLUSIONS:Ulinastatin injection combined with Xingnaojing injection can sig-nificantly decrease serum inflammatory factor levels,relieve craniocerebral injury,protect cerebral tissue and improve short-term prognosis with good safety.

Objective:To systematically evaluate the changes of serum nitric oxide (NO) content in adult patients with Kaschin-Beck disease (KBD).Methods:Systematic retrieval was conducted on China National Knowledge Infrastructure (CNKI), WanFang Data, VIP Database, PubMed, Embase and other databases, to analyze the literatures published from the database establishment to March 31, 2019, on the changes of serum NO content of adult patients with KBD. Meta-analysis was performed using Revman 5.3 software, and mean difference ( MD) and 95% confidence interval ( CI) were calculated; sensitivity analysis was performed using fixed-effect model or random-effect model based on heterogeneity results; and publication bias was evaluated using funnel chart. Results:Totally 7 qualified literatures were included, including 358 cases in the adult KBD group and 305 cases in the control group. After the heterogeneity test, there was heterogeneity among the literatures (χ 2 = 188.07, I2 = 97%, P < 0.01), so a random-effect model was used for Meta-analysis. The NO content in the KBD group was significantly higher than that in the control group (MD = 44.29, 95% CI: 30.57 - 58.00), the difference was statistically significant ( Z = 6.33, P < 0.01). Sensitivity analysis showed that the results of this study were stable. The two sides of the funnel were basically symmetrical, suggesting that the possibility of publication bias was small. Conclusion:The serum level of NO content in adult patients with KBD is significantly increased.

Objective:To investigate the molecular mechanism of excessive iodine induced experimental autoimmune thyroiditis (EAT) in mice.Methods:Sixty female non-obese diabetic (NOD) mice were selected and divided into 5 groups according to body weight [(25 ± 3) g] via the random number table method, with 12 mice in each group: control group (group A), 10-fold high iodine group (group B), 100-fold high iodine group (group C), 1 000-fold high iodine group (group D) and 1 000-fold high iodine combined with polyinosinic acid-polycytidylic acid [Poly (I:C)] group (group E). The experiment period was 16 weeks. Mice in each group drank purified water with sodium iodine (NaI) content of 0.000, 0.005, 0.050, 0.500 and 0.500 mg/L, respectively; mice in group E were intraperitoneally injected with Poly (I:C) at week 7 and week 15, respectively. At the end of the 16th week, mice were dissected and blood samples and thyroid tissue were taken. The levels of serum thyroid function indexes [thyroid stimulating hormone (TSH), free triiodothyronine (FT 3), free thyroxine (FT 4), and thyroid peroxidase antibody (TPOAb)] were detected by enzyme-linked immunosorbent assay (ELISA); the pathological changes of thyroid tissue were observed after hematoxylin-eosin (HE) staining; differentially expressed genes in thyroid tissue were detected by RNA-sequencing (RNA-seq), and analyzed by KEGG pathway; mRNA and protein levels of p38, intercellular adhesion molecule-1 (ICAM-1) and chemokine 10 (CXCL10) in thyroid tissue were detected by real-time fluorescence quantitative PCR (qPCR) and Western blotting, respectively. Results:There were statistically significant differences in serum levels of TSH (ng/ml: 6.53 ± 0.86, 6.61 ± 0.82, 7.68 ± 0.55, 7.93 ± 0.60, 8.73 ± 1.60), FT 3 (pg/ml: 59.35 ± 10.16, 53.73 ± 10.96, 46.19 ± 8.03, 41.01 ± 8.67, 34.21 ± 11.75), FT 4 (pg/ml: 136.74 ± 10.06, 124.33 ± 14.34, 101.80 ± 6.78, 91.37 ± 6.75, 73.29 ± 17.31), and TPOAb (U/ml: 130.81 ± 24.53, 145.47 ± 28.89, 166.52 ± 41.59, 199.78 ± 42.19, 201.99 ± 44.03) among the 5 groups of mice ( F = 4.77, 4.96, 23.12, 3.68, P < 0.05). Compared with group A, the serum TSH levels of mice in groups C, D and E were higher, the levels of FT 3 and FT 4 in groups B, C, D and E were lower, and the levels of TPOAb in groups D and E were higher, and the differences were statistically significant ( P < 0.05). HE staining showed that the thyroid follicle lesion in groups D and E was serious, and the EAT phenotype appeared in both groups. The differentially expressed genes were analyzed by KEGG pathway. Compared with group A, 8 metabolic pathways related to thyroid autoimmunity and inflammation were found in groups B, C, D and E. Further analysis found that 3 genes appeared in multiple pathways, namely p38, ICAM-1 and CXCL10. There were significant differences in the mRNA levels of p38, ICAM-1 and CXCL10 in thyroid tissue of the 5 groups of mice ( F = 14.77, 12.76, 16.39, P < 0.05); compared with group A, the mRNA levels of p38 in groups B, C, D and E were higher, and the mRNA levels of ICAM-1 and CXCL10 in groups C, D and E were higher ( P < 0.05). There were significant differences in the protein levels of p38, ICAM-1 and CXCL10 in thyroid tissue of the 5 groups of mice ( F = 7.97, 73.86, 18.02, P < 0.05); compared with group A, the protein levels of ICAM-1 and CXCL10 in groups B, C, D and E were higher ( P < 0.05). Conclusion:Excessive iodine promotes the occurrence and development of EAT in mice by up-regulating the expressions of p38 and ICAM-1 genes that are closely related to thyroid autoimmune and inflammatory responses.
