Objective:To evaluate the application value of preconceptional laparoscopic cervical cerclage(LCC)in improving the pregnancy outcomes with cervical incompetence(CIC).Methods:Clinical data of 112 pa-tients with CIC who underwent preconceptional LCC in The First Affiliated Hospital of Zhengzhou University from July 1,2014 to May 31,2023 were retrospectively reviewed.The surgical indications of preconceptional LCC in-cluded:failed transvaginal cervical cerclage(TCC)(42 patients),history of cervical surgery+failed TCC(7 pa-tients),unsuitability for TCC(10 patients)and strong request from patients(53 patients).The surgical situation and pregnancy outcome of preconceptional LCC were analyzed,and the gestational age of delivery before and af-ter preconceptional LCC surgery and different surgical indications were compared in postoperative delivery pa-tients who underwent preconceptional LCC.Results:The median operation time of 112 patients was 65.5 min,the median intraoperative blood loss was 10.0 ml,and there were no intraoperative complications.The postopera-tive hospital stay was 2.9±0.6 d.108 cases were followed up after surgery,with 77 cases of pregnancy and de-livery after LCC.A total of 205 deliveries were made before surgery,and 81 deliveries were made after surgery.Successful postoperative deliveries(delivery after 28 weeks)were 78(96.3% ),with an average gestational age 37.4±1.7 weeks.The preterm birth rate was 16.7%,term birth rate was 83.3% .The delivery rate at≥28 weeks after preconceptional LCC was significantly higher than the previous delivery rate of pre pregnancy LCC(96.3% vs.10.7%,P<0.05),and the gestational age was significantly prolonged(36.4±5.5 weeks vs.19.8±7.5 weeks,P<0.05).The postoperative delivery gestational week of preconceptional LCC with different surgical indi-cations was significantly later than the previous delivery gestational week of pre pregnancy LCC(P<0.05),ex-cept for the indication of unsuitability for TCC(P>0.05).Conclusions:Preconceptional LCC surgery is highly safe and can effectively prolong the gestational age and improve pregnancy outcomes in patients with CIC.It can be an effective treatment method for patients with a history of TCC failure.

Objective To observe the efficacy and safety of Morinda officinalis oligosaccharides in the continuation treatment of mild and moderate depression.Methods An open,single-arm,multi-center design was adopted in our study.Adult patients with mild and moderate depression who had received acute treatment of Morinda officinalis oligosaccharides were enrolled and continue to receive Morinda officinalis oligosaccharides capsules for 24 weeks,the dose remained unchanged during continuation treatment.The remission rate,recurrence rate,recurrence time,and the change from baseline to endpoint of Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),Clinical Global Impression-Severity(CGI-S)and Arizona Sexual Experience Scale(ASEX)were evaluated.The incidence of treatment-related adverse events was reported.Results The scores of HAMD-17 at baseline and after treatment were 6.60±1.87 and 5.85±4.18,scores of HAMA were 6.36±3.02 and 4.93±3.09,scores of CGI-S were 1.49±0.56 and 1.29±0.81,scores of ASEX were 15.92±4.72 and 15.57±5.26,with significant difference(P＜0.05).After continuation treatment,the remission rate was 54.59％(202 cases/370 cases),and the recurrence rate was 6.49％(24 cases/370 cases),the recurrence time was(64.67±42.47)days.The incidence of treatment-related adverse events was 15.35％(64 cases/417 cases).Conclusion Morinda officinalis oligosaccharides capsules can be effectively used for the continuation treatment of mild and moderate depression,and are well tolerated and safe.

By using thioflavin T(ThT)as displacement-based fluorescent probes,three kinds of aptasensors were constructed for rapid detection of three kinds of small molecules such as ochratoxin A(OTA),aflatoxin B1(AFB1)and adenosine.In the absence of target molecule,ThT bound with the aptamer to form an aptamer-ThT complex and exhibited a significant fluorescence response.Upon the addition of target molecule,because of the higher affinity between target and aptamer than that between ThT and the aptamer,ThT was displaced by the target molecule from the aptamer-ThT complex,resulting in weakened fluorescence signal.Based on this principle,the target molecule could be detected quantitatively.Further study through circular dichroism spectra showed that there was no significant change in the conformation of the aptamer after addition of ThT or target molecules.The stoichiometric ratios of ThT to OTAapt,AFB1apt and Adeapt measured through the method of equimolar continuous variation was 1∶1,1∶1 and 2∶1,respectively,and their dissociation constants were all larger than those between the target molecule and its aptamer.Therefore,the principle of this detection method was the displacement of fluorescent probe(ThT)in aptamer-ThT complex by target molecule,resulting in decrease of fluorescence intensity.Under optimal experimental conditions,the limits of detection(LODs)were 0.8 nmol/L for OTA,1.3 nmol/L for AFB1,and 0.10 μmol/L for adenosine,respectively.This method was label-free,simple to operate,with low cost,good selectivity and high sensitivity.The developed assay kit based on this method could be used for actual sample detection.
