Objective To explore the efficacy and safety of terminating biochemical pregnancy (the stage in which intrauterine or ectopic pregnancy cannot be confirmed) with mifepristone and misoprostol. Methods Mifepristone (150 mg) combined with misoprostol (600 ?g) 3 days later were given to 500 biochemical pregnancies (G_1),500 early clinical pregnancies (G_2) and 500 clinical pregnancies (G_3) which were classified according to amenorrhea days,serum human chorionic gonadotropin-beta subunit (?- hCG) and vaginal B-ultrasonic examinations.All were observed for 6 hours after taking misoprostol and returned for assessment per week.Results Expulsion of conceptus was G_1 123 (24.6%,123/500),G_2 438 (87.6%,438/500) and G_3 467 (93.4%,467/500).Failure rate was G_1 6 (1.2%,6/500),G_2 24 (4.8%,24/500) and G_3 79 (15.8%,79/500) for ongoing pregnancies,hospitalizations for suspected ectopic pregnancies and surgical intervention for heavy or long-time bleeding.Bleeding cases during the administration of mifepristone were G_1 272 (54.4%,272/500),G_2 141 (28.2%,141/500) and G_3 87 (17.4%,87/500);the mean bleeding days were G_1 (5.8?1.5),G_2 (9.0?2.9) and G_3 (14.3?5.9) days.Other side effects including abdominal pain,nausea,vomiting and diarrhea were low and light in each group,increasing with advancing gestational age.Menses recovery was 486 (97.2%,486/500),452 (90.4%,452/500) and 433 (86.6%,433/500) for each group on scheduled time.Satisfaction was 499 (99.8%,499/500),485 (97.0%,485/500) and 369 (73.8%,369/500) respectively.Conclusion Mifepristone and misoprostol in combination is as safe,and effective for termination of biochemical pregnancies as ordinary medical abortion.It does not need to wait till ectopie pregnancy is excluded.

Objective To study the significance of the cerebrospinal fluid(CSF)lactate level in diagnosing neonatal bacterial meningitis(BM). Methods The CSF samples were collected from neonates admitted to Neonatal Ward of Children's Hospital of Fudan University between January 2014 and March 2015. CSF lactate and glucose con-centrations were measured with blood - gas analyzer. CSF and serum glucose levels were measured with glucometer. The enrolled neonates were divided into 2 groups based on CSF culture,CSF white blood cells(WBCs)and clinical presenta-tion:observation group(neonates with BM)and control group(neonates without BM). Statistical analysis of data was performed with Stata 12. 0. Results A total of 93 infants(16 assigned to observation group and 77 assigned to control group)met the inclusion criteria. Neonates in observation group had higher median CSF lactate level(4. 2 mmol/ L)and CSF lactate/ glucose ratio(L/ Gcsf)(2. 32 mmol/ L),than those in control group(1. 3 mmol/ L,0. 52),and there were significant differences(Z = - 6. 19,- 5. 92,all P ﹤ 0. 05). CSF glucose levels were lower in observation group(me-dian,1. 25 mmol/ L)than those in control group(median,2. 5 mmol/ L),and the difference was significant(Z = 4. 97, P ﹤ 0. 05);CSF/ serum glucose ratio(CSF/ Sglu)were lower in observation group(median,0. 44 vs 0. 81 in control group),and the difference was significant(Z = 4. 43,P ﹤ 0. 05). The optimal CSF lactate cutoff point of 2. 2 mmol/ L had a positive predictive value(PPV)of 72. 7% and negative predictive value(NPV)of 100. 0% for bacterial meningi-tis. The optimal L/ Gcsf cutoff point of 1. 24 had a PPV of 94. 1% and NPV of 100. 0% . The optimal CSF glucose cutoff point of 2. 0 mmol/ L had a PPV of 65. 0% and NPV of 95. 9% . The optimal CSF/ Sglu cutoff point of 0. 6 had a PPV of 60. 0% and a NPV of 96. 9% . Conclusion CSF lactate may be an excellent biomarker for early diagnosis of neo-natal BM.

OBJECTIVES: To study the value of autotaxin (an autocrine motility factor) level in serum and bronchoalveolar lavage fluid (BALF) in predicting refractory Mycoplasma pneumoniae pneumonia (RMPP) in children and its correlation with interleukin-6 (IL-6), interleukin-8 (IL-8), and C-reactive protein (CRP). METHODS: A retrospective analysis was performed on 238 children with Mycoplasma pneumoniae pneumonia who were admitted from January 2019 to December 2021. According to disease severity, they were divided into two groups: RMPP (n=82) and general Mycoplasma pneumoniae pneumonia (GMPP; n=156). The two groups were compared in terms of the levels of autotaxin, IL-6, IL-8, and CRP in serum and BALF to study the value of autotaxin level in serum and BALF in predicting RMPP in children, as well as the correlation of autotaxin level with IL-6, IL-8, and CRP in children with RMPP. RESULTS: Compared with the GMPP group, the RMPP group had significantly higher levels of autotaxin, IL-6, IL-8, and CRP in serum and BALF (P<0.05). For the children with RMPP, the levels of autotaxin, IL-6, IL-8, and CRP in serum and BALF in the acute stage were significantly higher than those in the convalescent stage (P<0.05). The receiver operating characteristic (ROC) curve showed that the level of autotaxin in serum and BALF had a good value in predicting RMPP in children, with an area under the curve of 0.874 (95%CI: 0.816-0.935) and 0.862 (95%CI: 0.802-0.924), respectively. The correlation analysis showed that the level of autotaxin in serum and BALF was positively correlated with IL-6, IL-8, and CRP levels (P<0.001). CONCLUSIONS The level of autotaxin in serum and BALF increases and is correlated with the degree of disease recovery and inflammatory cytokines in children with RMPP. Autotaxin can be used as a predictive indicator for RMPP in children.

Objective To understand the pathogen detection of hospitalized patients before antimicrobial therapy in a hospital through implementation of comprehensive intervention measures,and provide reference basis for the de-velopment of targeted measures.Methods Hospitalized patients who received therapeutic antimicrobial agents in this hospital were selected as the research subjects.Patients who were hospitalized from January to May 2022 were selected as the pre-intervention group,comprehensive intervention measures were taken from June to October 2022,and those who were hospitalized from November 2022 to March 2023 were selected as the post-intervention group.The pathogen detection rate before antimicrobial therapy,sterile specimen detection rate,antimicrobial use rate,de-tection rate of key multidrug-resistant organisms of patients before and after the intervention were analyzed.Results Compared to before intervention,the proportion of pathogen detection rate before antimicrobial therapy(62.09％vs 74.04％),detection rate of healthcare-associated infection diagnosis-related pathogens(62.82％vs 92.73％),and sterile specimen detection rate(35.17％vs 41.06％)of hospitalized patients after intervention all increased signifi-cantly,with statistically significant differences(all P＜0.05).After intervention,pathogen detection rate before the combination use of key antimicrobial agents was not statistically different from before intervention(93.33％vs 90.48％,P＞0.05),while antimicrobial use rate was lower than before intervention(39.93％vs 44.95％,P＜0.05).There was no statistically significant difference in the detection rate of key multidrug-resistant organisms be-fore and after intervention(all P＞0.05).Conclusion Adopting scientific and rational intervention measures can improve the pathogen detection rate,provide a reference basis for the rational use of antimicrobial agents.There was no significant improvement in the pathogen detection rate before the combination use of key antimicrobial agents and the detection rate of key multidrug-resistant organisms,indicating that relevant measures still need to be further optimized.

To analyze and discuss placebo-related information in clinical research literatures in the past 30 years, including placebo's dosage form, ingredients, preparation process and quality control. Effort were made to research the CNKI. full-text database to preliminary find 700 placebo-related clinical research literature, screen out 301 eligible articles by hand, read the literatures to extract placebo-related information and make statistics and discussions. According to the results, Chinese randomized placebo-controlled clinical studies were characterized by diverse dosage forms of placebo with lack of reports for components, as evidenced by the only 17 literatures describing placebo's preparation or specific composition among the 301 literatures. Placebo-controlled clinical trials covered a wide range of disease spectra, but with a specific tropism of diseases in terms of system classification. Although placebo plays a key role in blinded clinical studies, researchers made less records of placebo, perhaps because they paid less attention to placebo or more attention to the research process or restricted by other objective conditions. Moreover, placebo production, quality control and quality evaluation also need to be further standardized.

PURPOSE: The aim of this study was to present our experience before establishing laparoscopic left lateral sectionectomy (LLLS) of the liver as a standard procedure, and to show efficacy of a totally LLLS compared to an open left lateral sectionectomy (OLLS). METHODS: We retrospectively analyzed and compared clinical outcomes (operation time, blood loss, hospital stay, complication rate, etc) for 29 patients who underwent LLLS and 27 patients who underwent OLLS between January, 2002 and December, 2009. To see the learning curve for LLLS, we arbitrarily divided the LLLSs we did into an early group (ELLLS) and a late group (LLLLS) based on when they were operated on relative to case number 14. RESULTS: Mean operative times for the ELLLS, LLLLS and OLLS groups were 269.7+/-102.6, 210.0+/-47.9 and 289.1+/-72.8 minutes, respectively. Mean operative time was significantly shorter (p<0.05) in the LLLLS than the OLLS group. Mean intra-operative blood loss was also less in the LLLLS group than the OLLS group (80.00+/-224.2 ml vs. 195.15+/-405.4 ml). Post-operative hospital stay was shorter in the LLLLS group than the OLLS group (9.9+/-4.0 versus 16.9+/-9.1, p=0.071). CONCLUSION: The totally LLLS is a safe, feasible treatment option that can be a standard procedure with better outcomes in selected patients after an initial learning curve.

A cobalt nanoparticles modified ITO electrode (NpCo/ITO) was prepared by casting cobalt nanoparticles onto ITO electrode and the cobalt nanoparticles were synthesized by NaHB4 reduction. The electrochemical behaviors of adriamycin (ADM) on NpCo/ITO were studied. The modified ITO electrode was characterized by cyclic voltammetry (CV), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). In a 0.01 mol L(-1) PBS (pH 8.0) buffer solution, a sensitive reduction peak of ADM was obtained. A linear relationship is held between the peak current and ADM concentration in the range of 1.0 x 10(-8) - 2.0 x 10(-6) mol L(-1) with detection of 5.0 x 10(-9) mol L(-1)- by cyclic voltammetry (CV) response. The reduction process was irreversible with adsorption at the NpCo/ITO electrode. The modified electrode showed an excellent electrocatalytic activity for the ADM electrochemical reduction.
