OBJECTIVETo compare the sedative effects of different doses of dexmedetomidine (DEX) and midazolam (MDZ) in dental implant surgery:
METHODSSixty patients undergoing dental implantation were selected and divided randomly into six groups (10 in each group). In group 1 (G1), a highdose of MDZ alone was administered intravenously. In group 2 (G2), a relatively low dose of MDZ and DEX was administered intravenously. In group 3 (G3), a highdose of MDZ and DEX was administered intravenously. In group 4 (G4), a lowdose of MDZ and a highdose of DEX were administered. In group 5(G5), a highdose of MDZ and a low dose of DEX were administered. In group 6 (G6), a highdose of DEX alone was administered intravenously. Blood pressure (BP), heart rate (HR), and arterial oxygen saturation values were measured. Sedation was assessed by determining the Ramsay sedation scores(RSS) during infiltration anesthesia (T1), incision (T2), cutting (T3), and suturing (T4). Before discharging from the hospital, patients were asked if they remembered the T1 to T4 procedures. The visual analogue scale (VAS) and the degree of patient satisfaction were assessed at the same time.
RESULTSIn T1 to T4, the systolic blood pressure (SBP) in G3 was the lowest and was significantly different from that in G1 and G2 (P < 0.05). In G1, the SBP was higher than that in G6 at the T3 and T4 points (P < 0.05). HR was below the preoperative (P < 0.05) in the G3 only. RSS was the lowest in G1 during the whole procedure. In G2, most patients obtained scores of 2-3. In G3, sedation was deeper, had more cases ofup to 5. In G4, most patients obtained scores of 3-4. In G5, some patients had a score of up to 5. The RSS in G6 was lower than that in G3 and G4 or G5 in T1 to T2, closer to G4 in T2. An evaluation of the VAS and the degree of patient satisfaction did not show any differences among the groups.
CONCLUSIONThe combination of DEX and MDZ is superior to a single intravenous injection. Low-dose MDZ combined with high-dose DEX achieved the highest quality of sedation in this study.

Background and purpose:The patients with aggressive lymphoma who have a poor prognosis and unlikely to be cured with conventional chemotherapy. This study was aimed to evaluate the effect of high-dose etoposide in mobilization followed auto-SCT in treating refractory lymphoma. Methods:40 patients [median age 33 (13-61) years] with refractory non-Hodgkin’s lymphoma (NHL, n=32) or Hodgkin’s lymphoma (HD, n=8) received high-dose etoposide [VP16 10-15 mg/(kg·d)×2 d] in mobilization in our center. Remission status prior to mobilization was PD (n=40). The use of such granulocyte colony-stimulating factor [G-CSF, 5-10μg/(kg·d)] mobilized peripheral blood stem cells (PBSC) after high-dose etoposide until the end of leukapheresis. Peripheral blood stem cell was collected and frozen in-80℃refrigerator. All these patients received auto peripheral blood stem cell transplantation (auto-PBSCT). Conditioning regimen was BEAM (n=19, 47.5%) or CBV (n=21, 52.5%). Results:Twenty-eight pa-tients (70%) were assessable for response after high-dose etoposide at a median pretreatment time of 39 days (range 17-172 days), 12 patients (30%) had no response. Median follow-up of 28 (4-66) months, 16 patients (40%) reached CR after auto-PBSCT. Fifteen of the 28 patients (53.6%) who had response to high-dose etoposide reached CR, 4 patients (14.3%) reached PR, 9 patients (32.1%) succumb to progression of disease. One of the 12 patients (8.3%) who had no response to high-dose etoposide reached CR, 1 patients (8.3%) reached PR, 10 patients (83.4%) succumb to progression of disease. The estimated 1-year OS and EFS were 69%and 56.7%respectively, 2-years OS and EFS were 63%and 52%respectively. The prognosis of the patients who had no response to etoposide was poor. The estimated 1-year OS and EFS were 25%and 16.7%respectively. Two group of comparison differences have statistics signiifcance (P<0.01). Conclusion: High-dose etoposide could be used in refractory lymphoma as rescue therapy in mobilization. It can increase the EFS and OS of patients who had response. The hematopoietic stem cells collection and hematopoietic reconstitution are not affected by etoposide.

Abstract: Objective To investigate the distribution and drug resistance of pathogenic bacteria separated from ascites of patients in Children’s Hospital Affiliated to Zhengzhou University from 2015 to 2021, and to provide a basis for rational clinical antimicrobial agents. Methods Bacterial culture, bacterial identification and drug sensitivity analysis were performed on 1 058 non-duplicate ascites culture specimens from January 2015 to December 2021. The clinica1 and microbiologica1 data were ana1yzed by WHONET 5.6 and SAS 9.4 Results Of the 1 058 specimens, 586 (55.39%) were positive for pathogenic bacteria, with a total of 781 strains isolated. There was no significant trend of increase or decrease in the positivity rate over different years. Male children (63.99%) were more prevalent than female children. Appendicitis (59.22%) was the most common disease and Escherichia coli was the most common causative bacteria. Among neonates (≤28 d), the bacteria with the highest detection rate were Klebsiella pneumoniae (23.50%) and Enterococcus faecium (23.50%), while among children (>28 d), the highest detection rate was Escherichia coli (35.98%). Gram-negative bacteria accounted for 64.79% of the 781 strains, mainly Escherichia coli (38.28%), Klebsiella pneumoniae (8.58%), and Pseudomonas aeruginosa (5.89%); Gram-positive bacteria accounted for 29.45%, mainly Enterococcus faecium (8.58%), Streptococcus constellatus (2.69%), and Enterococcus avium (2.43%); fungi accounted for 1.66% and anaerobic bacteria accounted for 4.10%. The resistance rates of Escherichia coli to cefoperazone/sulbactam, piperacillin/tazobactam, imipenem and meropenem were 6.02%, 4.35%, 4.35%, and 3.68%, respectively. The resistance rates of Klebsiella pneumoniae to these drugs were 59.70%, 59.70%, 50.75% and 53.73% respectively. Linezolid-resistant strains of Enterococcus faecium were found. Conclusion Appendicitis is the most common abdominal infection in children, and the distribution of ascites pathogens varies with ages and diseases. The pathogenic bacteria are mainly Gram-negative bacteria, and the drug resistance of Klebsiella pneumoniae was more serious. It is particularly important to use antibiotics correctly and rationally to reduce the emergence of drug resistant bacteria.

Objective To investigate the nutrition status of the focus groups of iodine deficiency in the 5 coastal counties(districts)in Guangxi in 2008 to propose corresponding prevention and control measures.Methods In the 5 coastal counties(districts)in Guangxi,including Haicheng,Tieshangang,Yinhai districts and Hepu county in Beihai city,Qinnan district in Qinzhou city,the rates of iodized salt coverage,qualified iodized salt and consumption of qualified iodized salt had always been below the average level of Guangxi.In the study,6 towns were randomly picked in Hepu district,and 3 towns were randomly picked in each of the other 4 coastal counties(districts).Two administrative viRages were randomly picked in each town.Forty children ages 8 to 10 and 10 women of child-beating age from 18 to 42 which included 5 pregnant and lactating women,were picked from each administrative village.Arsenic-cerium catalyzed spectrophotometry(WS/T 107-2006)Was used to determine the urinary iodine.Results In total,1437 urine samples of the children Were picked.The median of the children's urinary iodine Was 191.0μg/L,with 1.4%(20/1437)of the children's urinary iodine<20 μg/L,and 5.4%(77/1437)<50 μg/L, and 20.3%(292/1437) < 100 μg/L. The medians of the children's urinary iodine were 134.5 - 220.0 μg/L.In Haicheng and Hepu, the medians of the children's urinary iodine were higher than 200 μg/L(220.0,209.5 μg/L, respectively). The medians of the children's urinary iodine in the other 3 counties(districts) were within the suitable range between 100 and 200 μg/L(134.5,162.4,199.3 μg/L, respectively). The medians of the 8- and 9-year-old ehildren's urinary iodine (192.3,206.7 μg/L, respectively) were higher than that of the 10-year-old children's(157.2 μg/L, χ2 = 19.644,41.997, all P < 0.017). Totally, 365 urine samples of the women were picked.The medians of the women's urinary iodine in the 5 counties were 88.2 - 195.6 μg/L, with 195.6 μg/L in Haicheng and 156.5 μg/L in Hepu, and 88.2 μg/L in Tieshangang, which was the lowest and below 100 μg/L. The median of the childbearing-age women's urinary iodine was the highest(152.6 μg/L). The median of the lactating women's urinary iodine was the second (131.9 μg/L). The median of the pregnant women's urinary iodine was the lowest (89.4 μg/L) and below 100 μg/L. Only 6.7%(2/30) of the pregnant women's urinary iodine were within the suitable range between 150 and 250 μg,/L. Conclusions In the 5 coastal counties(districts) in Guangxi, 8 to 10-year-old children had good nutrition levels while childbearing-age and lactating women were within the suitable range. As a whole, the pregnant women had insufficient iodine nutrition. We propose that the iodine nutritional status of pregnant women is monitored routinely, with further prevention, control measures, health publicity and education necessary to improve iodized salt coverage.

This study is to investigate the anti-tumor activities of a novel cyclophosphamide derivate 4, 6-diphenyl cyclophosphamide (9b) in vivo and in vitro, and its possible mechanism of action. The inhibitory effects of 9b on human hepatoma cell line HepG2, human breast carcinoma cell line MCF-7 and human myeloid leukemia cell line K562 were measured by MTT assay in vitro. Cell cycle distribution and apoptotic rate were evaluated by flow cytometry. To evaluate the anti-tumor effect of 9b in vivo, mouse model bearing inoculated H22 tumor was established. The results indicated that 9b could inhibit the proliferation of HepG2, MCF-7 and K562 cells in a dose and time dependent manner. The ICo50 values of 9b were 32.34 micromol.L-1 to HepG2 cells, 87.07 micromol.L-1 to MCF-7 cells and 149.10 micromol.L-1 to K562 cells after incubation for 48 h. The results of flow cytometry indicated that after being treated for 48 h with different concentrations of 9b, the ratios of HepG2, MCF-7 cells at the Go/G1 phase and K562 cells at the G0/Gl phase and G2/M phase increased significantly compared with control group, and the apoptotic rate increased with the increase of the concentration of 9b. 9b could significantly reduce tumor weight of H22 solid tumor mouse model in vivo. To summarize, 9b showed significantly anti-tumor activity in vivo and in vitro, of which the mechanism might be associated with the change of cell cycle distribution and induction of tumor cell apoptosis.
