Objective:To observe the clinical outcomes of continued pregnancy in pregnant women with cesarean scar pregnancy (CSP).Methods:A retrospective analysis was performed on the pregnancy outcomes of 55 pregnant women who were diagnosed with CSP at the Second Affiliated Hospital of Army Medical University during the first trimester of pregnancy from August 1st, 2018 to October 31st, 2021 and strongly requested to continue the pregnancy.Results:Of the 55 pregnant women, 15 terminated the pregnancy in the first trimester, 1 underwent hysterotomy at 23 weeks of gestation due to cervical dilation, and 39 (71%, 39/55) continued pregnancy to the third trimester achieving live births via cesarean section. The gestational age of the 39 pregnant women delivered by cesarean section was 35 +6 weeks (range: 28 +5-39 +2 weeks), of whom 7 cases at 28 +5-33 +6 weeks, 20 cases at 34-36 +6 weeks, and 12 cases at 37-39 +2 weeks. The results of pathological examination were normal placenta in 3 cases (8%, 3/39), placenta creta in 4 cases (10%, 4/39), placenta increta in 9 cases (23%, 9/39) and placenta percreta in 23 cases (59%, 23/39). Among the 36 pregnant women who were pathologically confirmed as placenta accreta spectrum disorders (PAS) after surgery, the last prenatal ultrasonography showed placenta previa in 27 cases (75%, 27/36) and not observed placenta previa in 9 cases. The median intraoperative blood loss, autologous blood transfusion, and allogeneic suspended red blood cell infusion of 39 pregnant women during cesarean section were 1 000 ml (300-3 500 ml), 300 ml (0-2 000 ml) and 400 ml (0-2 400 ml), respectively. The uterine preservation rate was 100% (39/39), and only 1 case received cystostomy due to intracystic hemorrhage. The birth weight of the newborn was 2 580 g (1 350-3 800 g), and 1 case of mild asphyxia. Conclusions:Pregnant women with CSP who continue pregnancy under close monitoring after adequate ultrasound evaluation and doctor-patient communication could achieve better maternal and infant outcomes, but pregnant women with CSP are highly likely to continue pregnancy and develop into PAS. Effective hemostasis means and multidisciplinary team cooperation are needed in perinatal period for ensuring maternal and fetal safety.

To explore the application of gene chip technology in the acupuncture research so as to provide evidences for the mechanism of acupuncture for regulating bodies. The literature on the application of gene chip technology in the acupuncture field from 2001 to 2016 was collected in PubMed, Springer, CNKI and WANFANG databases, which was analyzed and summarized. There were some achievements of the technology for acupuncture research, focusing on the five aspects, including the study of the relationship between meridian-point and viscera, the influencing factors of acupuncture effect, the effect and mechanism of acupuncture analgesia, the mechanism of acupuncture anti-aging, the effect and mechanism of acupuncture for diseases of each system. Gene chip technology plays an important role in researching acupuncture mechanism. It is an important technology for genomics study of acupuncture. However, there are also some disadvantages such as high cost, deficient data mining, non-uniform observation objects, deficient professionals, etc. All those need further resolution so as to promote the application of this technology in the acupuncture researching field.

There are various contents about diagnosis and treatment of low back pain in(), which are closely related to meridians and collaterals, forming a complete theoretical system of meridian differentiation for low back pain. Its theory and application are interpreted in this paper from five main aspects, including 18 meridians and collaterals densely distributing in the tendons and bones of the waist, the pathogenesis of low back pain lying in the disorders of the meridianand blood, the nature of low back pain being reflected by the color and shape of meridians and collaterals, the disordered meridians of low back pain being first identified based on syndrome differentiation, the acupuncture prescription being selected according to meridian differentiation. The purpose of this paper is to guide clinical practice, explore the advantages and characteristics of meridian differentiation, and provide theoretical reference and evidence for promoting the standardization of TCM.
