Objective:To investigate the diagnostic value of pelvic floor ultrasound combined with electromyography physiological parameters for postpartum stress urinary incontinence(SUI)of different degrees and pelvic floor function of primipara.Methods:A total of 160 SUI patients who admitted to Yan'an hospital of Kunming City from January 2019 to January 2022 were selected,and they were divided into abnormal group(110 cases)and normal group(50 cases)according to pelvic floor function(the muscle voltage values of different muscle fibers).The SUI was graded according to the Chinese Guidelines for Diagnosis of Urological Diseases and the International Incontinence Advisory Committee's Incontinence Questionnaire(ICI-Q-SF).The posterior horn(α)of bladder and urethra at rest,the displacements of the bladder neck on y-axis(△y)and x-axis(△x)after the rest to the fatigue action,the proximal urethral rotation angle after the rest to the fatigue action(γ),the posterior horn of bladder and urethra(β)after the fatigue action were observed.The electromyography was used to draw and record the pelvic floor myoelectric activity signals of the patients of two groups at five stages(pre baseline rest period,class II muscle fiber systole period,class II and I muscle fiber systole period,class I muscle fiber systole period and post baseline rest period).And then,the muscle voltage values of different muscle fibers on the surface of pelvic floor were quantified.Results:There was no statistically significant difference in Δ x between patients with postpartum SUI of different degrees.There were significant differences in △y,α,β and γ between patients with postpartum SUI of different degrees(F=7.162,7.655,14.998,2.758,P<0.05).The differences of the means of muscle voltages of pre and post baseline rest period,and class I muscle fiber systole period among patients with postpartum SUI of different degrees were not significant.The differences of the means of muscle voltages of class II,and the class II and I muscle fiber systole period among patients with postpartum SUI of different degrees were significant(F=12.062,24.501,P<0.05),respectively.There was no statistically significant difference in △x between the two groups.The △y,α,β and γ of abnormal group were significantly higher than those of normal group(t=8.991,8.691,9.389,27.552,P<0.05),respectively.There were no statistically significant differences in the means of muscle voltage values of the pre and post baseline rest period,and class I muscle fibers systole period between the two groups.The means of muscle voltage values of class II,and class II and I muscle fibers systole period in the abnormal group was significantly higher than them in the normal group(t=9.613,14.452,P<0.05),respectively.The sensitivities of △y,α,β,γ,the means of class II muscle fibers systole period,and the means of class II and I muscle fibers systole period of pelvic floor ultrasound and electromyography physiological parameters were respectively 71.60%,79.40%,81.40%,91.20%,83.30%and 82.40%,and the specificities of them were respectively 41.40%,37.90%,37.90%,60.30%,41.40%,and 44.80%in diagnosing postpartum SUI of different degrees of primipara.The sensitivity and specificity of the combined diagnosis of them were respectively 92.20%and 82.80%in diagnosing postpartum SUI of different degrees of primipara.The sensitivities of △y,α,β,γ,the means of class II muscle fibers systole period,and the means of class II and I muscle fibers systole period of pelvic floor ultrasound and electromyography physiological parameters were respectively 79.10%,77.30%,88.20%,89.10%,77.30%,87.30%,and the specificities of them were respectively 64.00%,64.00%,52.00%,46.00%,70.00%and 66.00%in diagnosing pelvic floor function of primipara.The sensitivity and specificity of the combined diagnosis were respectively 98.20%and 80.00%in diagnosing pelvic floor function of primipara.Conclusion:Pelvic floor electromyography physiological parameters and pelvic floor ultrasonic parameters have a certain value in diagnosing postpartum SUI of different degrees and pelvic floor function,and the value of the combined diagnosis of them is higher.

Accumulating studies have demonstrated that non-coding RNAs (ncRNAs), functioning as important regulators of transcription and translation, are involved in the establishment and maintenance of pregnancy, especially the maternal immune adaptation process. The endometrial stromal cells (ESCs), trophoblast cells, and decidua immune cells that reside at the maternal-fetal interface are thought to play significant roles in normal pregnancy and pregnancy-associated diseases. Here, we reviewed the up-to-date evidence on how microRNA, long non-coding RNA, and circular RNA regulate ESCs, trophoblast cells, and immune cells and discussed the potential applications of these ncRNAs as diagnostic and therapeutic markers in pregnancy complications.

OBJECTIVE: To observe the effects of moxibustion on the stem cell factor (SCF)/tyrosine kinase receptor (c-kit) signaling pathway and immune function in rats with diarrhea irritable bowel syndrome (IBS-D), and to explore the mechanism of moxibustion for IBS-D. METHODS: Among 52 young rats born from 6 healthy pregnant SPF rats, 12 rats were randomly selected into the normal group, and the remaining 40 rats were treated with the three-factor combination method of maternal separation, acetic acid enema and chronic restraint stress to establish the IBS-D rat model. Thirty-six rats with successful IBS-D model were randomly divided into a model group, a moxibustion group, and a medication group, 12 rats in each group. The rats in the moxibustion group were treated with suspension moxibustion at "Tianshu" (ST 25) and "Shangjuxu" (ST 37); the rats in the medication group were treated with intragastric administration of rifaximin suspension (150 mg/kg). All the treatments were given once a day for 7 consecutive days. The body mass, loose stool rate (LSR), the minimum volume threshold when abdominal withdrawal reflex (AWR) scored 3 were measured before acetic acid enema (35 days old), after modeling (45 days old), and after intervention (53 days old). After intervention (53 days old), HE staining was used to observe the morphology of colon tissue, and spleen and thymus coefficients were measured; ELISA method was used to detect serum inflammatory factors (tumor necrosis factor a [TNF-a], interleukin [IL]-10, IL-8), T-lymphocyte subsets (CD⁺₄, CD⁺₈, CD⁺₄₅), value of CD⁺₄/CD⁺₈ and immune globulin (IgA, IgG, IgM); real-time PCR method and Western blot method was used to detect the expression of SCF, c-kit mRNA and protein in colon tissue; immunofluorescence staining method were used to detect positive expression of SCF and c-kit. RESULTS: After intervention, compared with the normal group, in the model group, the body mass and the minimum volume threshold when AWR scored 3 were decreased (P<0.01), LSR, spleen and thymus coefficients, serum levels of TNF-α, IL-8, CD⁺₄, CD⁺₄₅, CD⁺₄/CD⁺₈, IgA, IgG, IgM were increased (P<0.01), serum IL-10 level and protein and mRNA expression of SCF and c-kit in colon tissue were decreased (P<0.01), and the positive expression of SCF and c-kit was decreased (P<0.01). Compared with the model group, in the moxibustion group and the medication group, the body mass and the minimum volume threshold when AWR scored 3 were increased (P<0.01, P<0.05), LSR, spleen and thymus coefficients, serum levels of TNF-α, IL-8, CD⁺₄, CD⁺₈, CD⁺₄₅, CD⁺₄/CD⁺₈, IgA, IgG, IgM were decreased (P<0.01, P<0.05), serum IL-10 level and protein and mRNA expression of SCF and c-kit in colon tissue were increased (P<0.01), and the positive expression of SCF and c-kit was increased (P<0.01). Compared with the medication group, in the moxibustion group, the level of serum CD⁺₄ was decreased (P<0.05), the value of CD⁺₄/CD⁺₈ was increased (P<0.01), and there was no significant difference in other indexes (P>0.05). The expression of SCF and c-kit mRNA was positively correlated with the minimum volume threshold when AWR scored 3 and IL-10 (P<0.01), and negatively correlated with remaining indexes (P<0.01, P<0.05). CONCLUSION Moxibustion could reduce visceral hypersensitivity, improve symptoms of abdominal pain and diarrhea in IBS-D rats, and its mechanism may be related to up-regulation of the expression of SCF/c-kit signaling pathway and improvement of IBS-D immune function.

Objective: To evaluate the efficacy and safety of bendamustine combined with pomalidomide and dexamethasone (BPD regimen) in the treatment of relapsed multiple myeloma (MM) with extramedullary disease. Methods: This open, single-arm, multicenter prospective cohort study included 30 relapsed MM patients with extramedullary disease diagnosed in seven hospitals including Qingdao Municipal Hospital. The patients were treated with BPD regimen from February 2021 to November 2022. This study analyzed the efficacy and adverse reactions of the BPD regimen. Results: The median age of the 30 patients was 62 (47-72) years, of which 18 (60% ) had first-time recurrence. The overall response rate (ORR) of the 18 patients with first-time recurrence was 100%, of which three (16.7% ) achieved complete remission, 10 (55.5% ) achieved very good partial remission (VGPR), and five (27.8% ) achieved partial remission (PR). The ORR of 12 patients with recurrence after second-line or above treatment was 50%, including zero patients with ≥VGPR and six patients (50% ) with PR. Three cases (25% ) had stable disease, and three cases (25% ) had disease progression. The one-year progression free survival rate of all patients was 65.2% (95% CI 37.2% -83.1% ), and the 1-year overall survival rate was 90.0% (95% CI 76.2% -95.4% ). The common grade 3-4 hematology adverse reactions included two cases (6.7% ) of neutropenia and one case (3.3% ) of thrombocytopenia. The overall adverse reactions are controllable. Conclusions: The BPD regimen has good efficacy and tolerance in relapsed MM patients with extramedullary disease.

Objective: To investigate the clinical characteristics and maternal and fetal prognosis of pregnant women with acute fatty liver of pregnancy (AFLP). Methods: The clinical data of 86 AFLP pregnant women admitted to the Third Affiliated Hospital of Guangzhou Medical University from September 2017 to August 2022 were collected, and their general data, clinical characteristics, laboratory tests and maternal and fetal outcomes were retrospectively analyzed. Results: (1) General information: the age of the 86 pregnant women with AFLP was (30.8±5.4) years, and the body mass index was (21.0±2.5) kg/m². There were 50 primiparas (58.1%, 50/86) and 36 multiparas (41.9%, 36/86). There were 64 singleton pregnancies (74.4%, 64/86) and 22 twin pregnancies (25.6%, 22/86). (2) Clinical characteristics: the main complaints of AFLP pregnant women were gastrointestinal symptoms, including epigastric pain (68.6%, 59/86), nausea (47.7%, 41/86), anorexia (46.5%, 40/86), vomiting (39.5%, 34/86). The main non-gastrointestinal symptoms were jaundice of skin and/or scleral (54.7%, 47/86), edema (38.4%, 33/86), fatigue (19.8%, 17/86), bleeding tendency (16.3%, 14/86), polydipsia or polyuria (14.0%, 12/86), skin itching (8.1%, 7/86), and 17.4% (15/86) AFLP pregnant women had no obvious symptoms. (3) Laboratory tests: the incidence of liver and kidney dysfunction and abnormal coagulation function in AFLP pregnant women was high, and the levels of blood ammonia, lactate dehydrogenase and lactic acid were increased, and the levels of hemoglobin, platelet and albumin decreased. However, only 24 cases (27.9%, 24/86) of AFLP pregnant women showed fatty liver by imageology examination. (4) Pregnancy outcomes: ① AFLP pregnant women had a high incidence of pregnancy complications, mainly including renal insufficiency (95.3%, 82/86), preterm birth (46.5%, 40/86), hypertensive disorders in pregnancy (30.2%, 26/86), gestational diabetes mellitus (36.0%, 31/86), fetal distress (24.4%, 21/86), pulmonary infection (23.3%, 20/86), disseminated intravascular coagulation (16.3%, 14/86), multiple organ dysfunction syndrome (16.3%, 14/86), hepatic encephalopathy (9.3%, 8/86), and intrauterine fetal death (2.3%, 2/86). ② Treatment and outcome of AFLP pregnant women: the intensive care unit transfer rate of AFLP pregnant women was 66.3% (57/86). 82 cases were improved and discharged after treatment, 2 cases were transferred to other hospitals for follow-up treatment, and 2 cases (2.3%, 2/86) died. ③ Neonatal outcomes: except for 2 cases of intrauterine death, a total of 106 neonates were delivered, including 39 cases (36.8%, 39/106) of neonatal asphyxia, 63 cases (59.4%, 63/106) of neonatal intensive care unit admission, and 3 cases (2.8%, 3/106) of neonatal death. Conclusions: AFLP is a severe obstetric complication, which is harmful to mother and fetus. In the process of clinical diagnosis and treatment, attention should be paid to the clinical manifestations and laboratory tests of pregnant women, early diagnosis and active treatment, so as to improve maternal and fetal outcomes.

OBJECTIVE: To detect the relative expression of IGLL1 (immunoglobulin lambda-like polypeptide 1) mRNA in bone marrow of children with T-cell acute lymphoblastic leukemia (T-ALL), and analyze its correlation with the clinical characteristics and prognosis of the patients, so as to clarify the clinical significance of IGLL1 in pediatric T-ALL patients. METHODS: A total of 56 pediatric T-ALL patients hospitalized in Children's Hospital of Soochow University from June 2012 to December 2017 and treated with CCLG-ALL 2008 regimen were selected. Transcriptome sequencing technology was used to detect the transcription level of IGLL1 gene in children with T-ALL. According to 25% of the IGLL1 transcription level (cutoff value:448), the enrolled children were divided into IGLL1 low expression group (17 cases) and IGLL1 high expression group (39 cases). Combined with clinical data, the correlation between the expression level of IGLL1 and prognosis of the patients was analyzed. RESULTS: The comparative analysis showed that the transcription level of IGLL1 was not correlated with the clinical characteristics of the patients, such as sex, age, bone marrow blast, white blood cell (WBC) count at initial diagnosis. The 5-year OS rate of patients with high IGLL1 expression was significantly higher than that of patients with low IGLL1 expression (76.9%±6.7% vs 47.1%±12.1%, P =0.018). Further comparison of relapse-free survival (RFS) rate between the two groups showed that the 5-year RFS rate of patients with high IGLL1 expression was higher than that of patients with low IGLL1 expression, but the difference between the two groups was not statistically significant (P =0.095). Multivariate COX analysis was conducted on common clinical prognostic factors (age, sex, WBC count at diagnosis, prednisone response on the 7th day, bone marrow response on the 15th day after treatment) and IGLL1 expression level, and the results showed that IGLL1 expression (P =0.012) and prednisone response (P =0.017) were independent risk factors for overall survival in pediatric T-ALL patients. CONCLUSION In pediatric T-ALL, the OS rate of children with high expression of IGLL1 gene was significantly higher than that of children with low expression of IGLL1 gene, and the expression level of IGLL1 gene was an independent factor affecting the survival of children with T-ALL, which suggests that IGLL1 is a marker of good clinical prognosis of children with T-ALL.

OBJECTIVE: To observe the efficacy and safety of different induction regimens of same total dosage of azacitidine (Aza), including standard dose (standard dose group) and low-dose long-term (adjusted dose group), in the treatment of elderly acute myeloid leukemia (AML). METHODS: A total of 103 elderly patients with AML (non-acute promyelocytic leukemia) from January 2020 to June 2021 were enrolled. Aza was administered at the standard dose of 75 mg/(m²·d) for 7 days in the standard dose group (50 cases), while at 100 mg/d for 7-12 days in the adjusted dose group (53 cases). The administration days in adjusted dose group was calculated based on the total standard dose of the patient's single course of treatment. The efficacy and safety between standard dose group and adjusted dose group were compared. Subgroup analysis were performed in the two groups for Aza alone, Aza combined with BCL-2 inhibitor, and Aza combined with low-dose chemotherapy for efficacy and safety. RESULTS: There were no significant differences in overall response rate (ORR), incidence of adverse reaction, and 1-year overall survival (OS) rate between standard dose group and adjusted dose group (P >0.05). The ORR of combination was higher than that of Aza alone (P < 0.05), while there was no significant difference in ORR between Aza combined with BCL-2 inhibitor and Aza combined with low-dose chemotherapy (P >0.05). The combination of BCL-2 inhibitor did not increase the incidence of adverse reactions compared wtih Aza alone. There was a higher risk of myelosuppression and pulmonary infection with a combination of low-dose chemotherapy than with a combination of BCL-2 inhibitor and Aza alone (P <0.05). No significant difference was observed in 1-year OS between Aza alone, Aza combined with BCL-2 inhibitor, and Aza combined with low-dose chemotherapy (P >0.05). CONCLUSIONS Both two induction regimens can be used in elderly AML patients who cannot tolerate intensive chemotherapy with similar overall effectiveness and safety. Aza combined with low-dose chemotherapy may result in increased ORR and an increased incidence of serious adverse reactions, and may not result in longer survival compared with Aza alone. Aza combined with BCL-2 inhibitor not only has similar effect in complete remission, objective response rate, and OS compared with Aza combined with low-dose chemotherapy, but also has higher safety.

Objective: To evaluate the impact of bleomycin/etoposide/cisplatin (BEP) and paclitaxel/carboplatin (PC) chemotherapy regimens on the fertility and prognostic outcomes in malignant ovarian germ cell tumor (MOGCT) patients who underwent fertility-sparing surgery (FSS). Methods: A propensity score matching algorithm was performed between the BEP and PC groups. The χ2 test and the Kaplan-Meier method were used to compare the fertility outcome, disease-free survival (DFS) and overall survival (OS). The Cox proportional hazards regression analysis was used to identify risk factor of DFS. Results: We included 213 patients, 185 (86.9%) underwent BEP chemotherapy, and 28 (13.1%) underwent PC chemotherapy. The median age was 22 years (range, 8–44 years), and the median follow-up period was 63 months (range, 2–191 months). Fifty-one (29.3%) patients had a pregnancy plan, and 35 (85.4%) delivered successfully. In the before and after propensity score matching cohorts, there were no significant differences in spontaneous abortion, selective termination of pregnancy, during-pregnancy status, and live birth between the BEP and PC groups (p>0.05). Fourteen (6.6%) patients experienced recurrence, including 11 (5.9%) in the BEP group and 3 (10.7%) in the PC group. Four (1.9%) patients in the BEP group died. Kaplan-Meier analysis revealed no significant differences in DFS (p=0.328) and OS (p=0.446) between the BEP and PC groups, and the same survival results were observed in the after matching cohort. Conclusion The PC regimen is as safe as the BEP regimen for MOGCT patients with fertility preservation treatment, and no differences were observed in fertility and clinical prognosis.

OBJECTIVE: To observe the regulative effect of Tongdu Tiaoshen acupuncture on the depression-like behavior and cAMP-response element binding protein (CREB)/brain-derived neurotrophic factor (BDNF)/tyrosine protein kinase B (TrkB) signaling pathway of hippocampus in rats with post-stroke depression (PSD), and to explore its possible mechanism on improving PSD. METHODS: A total of 36 SPF SD rats were randomized into a sham operation group, a model group and a Tongdu Tiaoshen group, 12 rats in each group. The compound method of Zea Longa suture-occlusion and chronic unpredictable mild stress (CUMS) was used to establish the PSD model in rats of the model group and the Tongdu Tiaoshen group. On the 4th day after modeling, acupuncture was applied at "Dazhui" (GV 14), "Shuigou" (GV 26), "Baihui" (GV 20) and "Shenting" (GV 24) in the Tongdu Tiaoshen group, 40 min every time, once a day, 6 times a week for 4 weeks consecutively. On the 2nd day after PSD modeling and after 4-week intervention, Zea Longa neurobehavioral score was evaluated, sucrose water consumption test and open-field test were performed; biochemical method was used to detect the SOD, CAT activity and MDA level in hippocampal CA1 area; ELISA method was used to detect the serum level of BDNF; real-time PCR was used to detect the mRNA expression of BDNF, TrkB and CREB in hippocampal CA1 area; Western blot was used to detect the protein expression of BDNF, TrkB, CREB and p-CREB in hippocampal CA1 area. RESULTS: Compared with the sham operation group, Zea Longa neurobehavioral scores were increased (P<0.05), percentage of sucrose water consumption, horizontal motion and vertical motion scores of open-field test were decreased after modeling and intervention in the model group and after modeling in the Tongdu Tiaoshen group (P<0.05). Compared with the model group, Zea Longa neurobehavioral score was decreased (P<0.05), percentage of sucrose water consumption, horizontal motion and vertical motion scores of open-field test were increased after intervention in the Tongdu Tiaoshen group (P<0.05). Compared with the sham operation group, the SOD and CAT activity in hippocampal CA1 area and serum level of BDNF were decreased (P<0.05), MDA level in hippocampal CA1 area was increased in the model group (P<0.05); compared with the model group, the SOD and CAT activity in hippocampal CA1 area and serum level of BDNF were increased (P<0.05), MDA level was decreased in the Tongdu Tiaoshen group (P<0.05). Compared with the sham operation group, the mRNA expression of BDNF, TrkB and CREB as well as the protein expression of BDNF, TrkB, CREB and p-CREB were decreased in hippocampal CA1 area in the model group (P<0.05); compared with the model group, the mRNA expression of BDNF, TrkB and CREB, the protein expression of BDNF, TrkB and p-CREB as well as the ratio of p-CREB/CREB were increased in the Tongdu Tiaoshen group (P<0.05). CONCLUSION Tongdu Tiaoshen acupuncture can improve the depression-like behavior in PSD rats, the mechanism may be related to the inhibition of oxidative stress in hippocampal tissues and the enhanced activity of CREB/BDNF/TrkB signaling pathway.
