ObjectiveTo overview of systematic reviews of the efficacy and safety of antimicrobials in the prevention of postpartum infection after vaginal delivery, and to provide evidence for the rational use of antimicrobials. MethodsThe CNKI, WanFang Data, VIP, PubMed, Embase, and Cochrane Library databases were searched to collect systematic reviews/meta-analyses on antibiotic prophylaxis for transvaginal delivery from inception to June 25, 2023. The data of the included systematic reviews were extracted by 2 investigators independently, and the methodological quality, risk of bias, and report quality were evaluated by AMSTAR 2.0 scale, ROBIS tool, and PRISMA, respectively. And a pool of outcomes for assessing the effectiveness of antimicrobials in prevention of postpartum infection after transvaginal delivery was developed. ResultsA total of 7 systematic reviews were included. And the AMSTAR 2.0 indicated that most studies (5/7) were from very low quality to low quality. The ROBIS tool showed 3 studies with low risk of bias, 3 with high risk of bias, and 1 with unclear risk of bias. The results of the PRISMA statement showed that the included system evaluation reports were relatively complete. The present evidence showed that prophylactic use of antimicrobials may be beneficial and recommended in women with Ⅲ-Ⅳ perineal fissures, with no significant benefit in women with manual placenta removal, but prophylactic use of antimicrobials was recommended considering their invasive nature, but it was controversial whether antimicrobials should be used in the categories of vaginal assisted delivery, perineal lateralization, and spontaneous delivery (without complications). ConclusionAntimicrobial prophylaxis may not be recommended for all the pregnant women undergoing vaginal delivery to prevent the postpartum infection, but considering the low methodological quality of the included systematic review and the inconsistent outcomes in this field, the conclusion should be further verified by future research with high-quality.
ObjectiveTo summarize the research progress of mucinous breast cancer (MBC). MethodsLiteratures about the recent studies of MBC were reviewed. ResultsMBC was one of special subtype of infiltrating breast cancer. According to the mucus ingredient in the ratio of the mass, MBC was divided into pure mucinous breast cancer (PMBC) and mixed mucinous breast cancer (MMBC). Compared to infiltrating ductal cancer-not otherwise specified (IDC-NOS), MBC showed higher positive expression rates of estrogen receptor (ER) and progestrogen receptor (PR), with reduced lymph node metastasis rate and better prognosis. PMBC had lower lymph node metastasis rate and better outcome than MMBC. ConclusionsThere is significant difference about clinical and pathological characteristics between MBC and IDC-NOS. Researches are generally believed that MBC is an uncommon breast neoplasm which is associated with a good prognosis.
ObjectiveTo establish a normal reference value range of specific thyroid function in pregnant women corresponding to Beckman reagent in Chengdu.MethodsWe randomly selected 120 non-pregnant women and 445 pregnant women who underwent routine examinations at the First Affiliated Hospital of Chengdu Medical College from November 2016 to June 2017; tested for free triiodothyronine (FT3), free thyroxine (FT4), and thyroid stimulating hormone (TSH) in serum; used SPSS 24.0 to calculate the bilateral limit of each index (Section 2.5, 97. 5 Quot); established the normal range of Beckman reagent.ResultsThe reference ranges of FT3, FT4, and TSH in the first, second, and third trimester of pregnancy were 4.41–6.33, 4.17–6.12, and 3.86–6.39 pmol/L; 7.64–14.63, 6.62–13.69, and 6.62–12.51 pmol/L; 0.21–3.62, 0.16–4.35, and 0.89–4.88 mU/L; respectively. There was no significant difference in serum TSH between the first and second trimester (P>0.05), and neither between the first and second trimesters and the controls in serum FT3 (P>0.05). The differences in serum FT3, FT4, and TSH among the rest of trimesters, and between each trimester and the normal control group were statistically significant (P<0.05). There was a significant correlation between TSH and FT4 in the early and middle stages of pregnancy (r=–0.277, –0.392, P<0.01).ConclusionThe reference value of FT3, FT4, and TSH in pregnant women with Beckman reagent was significantly different from that in non-pregnant women.

One groupconsisted of 20 cases in all 22 limbs used the transplantation of autologous PBSC,and another group included 16 cases in all 17 limbs were not use this technique.Multifunction monitoring device,dopplor ultrasound monitoring device,per cutem oxygen partial pressure monitoring device and digital subtraction angiography were used to measure effect degree of limbs regional blood flow from cutaneous covering,blood vessel and blood on the preoperative and postoperative days and the follow-up time was six months.ResultsThe effect indexes of limbs regional blood flow of the case by transplantation of autologous PBSC was as follows:skin temperature index(STI)was(1.5±0.3) ℃， per cutem oxygen partial pressure monitoring device(TcPO2)was(36.6±9.3)mm Hg,ankle-brachium index(ABI)was0.7±0.1,photoplethysmograpy index(PPGI) was0.8±0.1,saturation of blood oxygen(SaO2)was(78.3±15.9)%,digital subtraction angiography score was1.5±0.3,the rate of limbs salvage was 82%,the distance of intermittent claudication was(150.3±41.1)meters,and the change of index was consistent with ameliorative tendency of symptom(0.415＜r＜0.592, P＜0.05).ConclusionThe transplantation of autologous PBSC can promote blood flowremodeling in limbs ischemia,and the effect indexes of limbs regional blood flow can objectively reflect the degree of blood flow remodeling.
Objective To investigate the relationship between the tibia callus diameter ratio(CDR) and prognosis during tibial distraction and the occurrenceof late deformity or fracture. Methods We measured tibiallengthening callus diameter and added up the cases of angular deformity and fracture in 68 casesfrom January 1996 to December 2001, to calculated callus diameter ratios and compare the relationship between the tibia callus diameter during tibial distraction and the occurrence of late callus angular deformity or fracture. Results In 23 cases of CDRlt;80%, 13 cases had new bone fracture, 21 cases had angular deformity gt;5 degree. In 6 cases of 81%lt;CDRlt;85%, there were 4 cases of angular deformity gt;5 degree. In the other 39 cases of CDRgt;85%, there were no fracture and angular deformity. Conclusion When the CDR was gt;85%, there wereno angular deformity and fracture, but when the CDR was lt;80%, the complications of fracture and angular deformity occur. CDR is a better alarming index for preventing the complications occurring in tibial lengthening.
ObjectiveTo establish a systematic, scientific, and sensitive index system to provide a scientific basis for quality evaluation and comprehensive quality management of day surgery nursing.MethodsThe databases of Wanfang, China National Knowledge Infrastructure, CQVIP, PubMed, and Web of Science were searched. The retrieval time was from the establishment of the databases to 15th July, 2019. Based on the “structure-process-outcome” management model, Delphi method was used to conduct two rounds of expert consultation for nursing experts related to day surgery in five tertiary hospitals. The results of the consultation were sorted out and the consensus of experts was obtained, so as to determine the quality-sensitive indicators of day surgery nursing.ResultsA total of 20 nursing experts participated in the questionnaire survey. The final evaluation indicators determined by expert correspondence included 1 structural indicator, 9 process indicators, and 4 outcome indicators.ConclusionsThe construction of quality evaluation standard of day surgery nursing not only embodies the connotation of nursing management of day surgery, but also puts forward clear requirements and quality standards for specialized nursing management. It has high reliability, scientificity, and strong operability, which can effectively improve the quality of nursing management and service level of day surgery.
Objective To establish a risk evaluation indicator system for intrauterine device (IUD), to determine the weight of indicators, to comprehensively evaluate the risk of IUDs by using a variety of comprehensive evaluation methods according to the data of IUDs, so as to provide references for the government purchasing decision-making. Methods The literature review, long-term monitoring of IUD adverse events, large sample randomized controlled trials (RCTs) and Delphi methods were applied to establish the risk evaluation indicator system for IUD. The weight of each indicator was determined by jointly using the subjective scoring method and CRITIC method. Based on the established indicator system, primary research (RCT) data and secondary research data (literature data), the analytic hierarchy process (AHP), technique for order preference by similarity to ideal solution (TOPSIS) and synthetical scored method were used to assess the risk of IUDs respectively, and then the assessment results of three methods were integrated to obtain a comprehensive rank of various IUDs. Results A two-level risk evaluation indicator system for IUD was established and the seven 1st level indicators included unwanted pregnancy, expulsion, menstruation problems, pain, IUD ectopia, position and shape changes as well as total health problems, which were divided into 26 2nd level indicators. Through the subjective and objective weighting method, the weights of each 1st level indicator were 0.147 5, 0.144 3, 0.140 7, 0.174 8, 0.163 2, 0.132 8, and 0.096 6, respectively. The risk evaluation of the above three methods showed that among the three kinds of IUD in a multicenter RCT, yuangong365 was with the lowest risk, followed by TCu380A and MLCu375. The risk evaluation showed that among the 14 kinds of IUD from literatures, medicated γ IUD was with the lowest risk, followed by HCu280, yuangong365, and Gyne IUD, while the medicated stainless steel ring 165 was with the highest risk. Conclusion The established indicator system has a good representation and credibility, and the ways to identify the weight of indicators are scientific, comprehensive and accurate. Meanwhile, the findings which were demonstrated by various assessing methods are consistent to a large extent. Now that medicated γ IUD and HCu280 have been already included in the National Coverage Plan, it is suggested that if the prices of yuangong365 and Gyne IUD are reasonable, the two IUDs could be considered to be listed in the National Coverage Plan and freely chosen by women of child-bearing age.
The measurement of network is one of the important researches in resolving neuronal population information processing mechanism using complex network theory. For the quantitative measurement problem of functional neural network, the relation between the measure indexes, i.e. the clustering coefficient, the global efficiency, the characteristic path length and the transitivity, and the network topology was analyzed. Then, the spike-based functional neural network was established and the simulation results showed that the measured network could represent the original neural connections among neurons. On the basis of the former work, the coding of functional neural network in nidopallium caudolaterale (NCL) about pigeon's motion behaviors was studied. We found that the NCL functional neural network effectively encoded the motion behaviors of the pigeon, and there were significant differences in four indexes among the left-turning, the forward and the right-turning. Overall, the establishment method of spike-based functional neural network is available and it is an effective tool to parse the brain information processing mechanism.
