Objective To explore the status and influencing factors of nausea and vomiting after radical resection of liver cancer. Methods A retrospective analysis was conducted on 70 liver cancer patients admitted to the Second People’s Hospital of Tianjin from May 2022 to May 2024. All patients underwent radical surgery for liver cancer,and their postoperative nausea and vomiting conditions were analyzed. According to the occurrence of nausea and vomiting, 30 patients who experienced nausea and vomiting after surgery were divided into an observation group, and the remaining 40 patients were divided into a control group. The clinical and pathological characteristics as well as perioperative indicators between two groups of patients were compared. A logistic regression model was established to analyze the influencing factors of postoperative nausea and vomiting in liver cancer patients after surgical resection,with postoperative nausea and vomiting as the dependent variable. Results The incidence of postoperative nausea and vomiting in liver cancer patients was 42. 86%（30/70）, including 14 cases of grade I, accounting for 20. 00%, 10 cases of grade II, accounting for 14. 29%, four cases of grade III,accounting for 5. 71%, and two cases of grade IV,accounting for 2. 86%. There were no significant differences in gender,body mass index（BMI）, pathological type,clinical stage,and preoperative fasting time between the observation group and the control group（P>0. 05）. However, there were significant differences in age and chemotherapy status between the observation group and the control group（P<0. 05）. There were no significant differences in the operation time,postoperative VAS score,anesthesia method and postoperative complications between the observation group and the control group（P>0. 05）, but with differences in the portal block time,intraoperative blood loss and postoperative abdominal distension between the observation group and the control group（P<0. 05）. Age, chemotherapy, intraoperative blood loss, and postoperative abdominal distension were independent influencing factors for postoperative nausea and vomiting in liver cancer patients undergoing surgical resection（P<0. 05）. Conclusions The incidence of nausea and vomiting after surgical resection in liver cancer patients is relatively high, with age, chemotherapy, intraoperative blood loss, and postoperative abdominal distension may be influencing factors for nausea and vomiting. Therefore, relevant measures should be taken in a timely manner to intervene in high-risk patients to prevent postoperative nausea and vomiting and reduce its severity.

Objective To explore the current situation and influencing factors of bladder spasms in patients after kidney transplantation. Methods Selecting 80 kidney transplant patients admitted to the First Affiliated Hospital of Guangzhou Medical University from December 2022 to April 2024 as the research subjects, the occurrence of postoperative bladder spasm was recorded. Fifteen patients who experienced bladder spasm after surgery were included in the bladder spasm group, and the remaining 65 patients were included in the non bladder spasm group. The general demographic data,preoperative clinical data, intraoperative and postoperative conditions between two groups were compared. Incorporating bladder spasm as the dependent variable into the Logistics regression model to analyze the influencing factors of bladder spasm after kidney transplantation. Results A total of 15 out of 80 kidney transplant patients experienced bladder spasms after surgery, accounting for 18. 76%. By comparing general demographic data between the bladder spasm group and the non bladder spasm group, it was found that there were no significant differences in gender, age, Body Mass Index, education level, payment methods, and household income（P>0. 05）. There was no significant differences in primary disease, combined basic disease, and dialysis method between the two groups（P>0. 05）,while there were significant differences in preoperative dialysis time and preoperative anemia between the two groups（P<0. 05）. Surgical time, intraoperative blood loss,postoperative urinary retention, postoperative visual analog scale score, C reactive protein, tumor necrosis factor-α, interleukin-6, alkaline phosphatase, transaminase, creatinine, urea nitrogen, cystatin C were not different between the two groups（P>0. 05）. The difference in the mean urine volume after seven days and urinary catheter material were significant（P<0. 05）. According to the results of the Logistic regression analysis,preoperative dialysis duration（95%CI：1. 327-9. 846,OR：3. 614, P=0. 012）, preoperative anemia（95%CI：0. 995-1. 000,OR：0. 997, P=0. 045）, catheter material（95%CI：1. 498-3 199. 687,OR：69. 239, P=0. 030）, and mean urine output at seven days postoperatively（95%CI：1. 058-334. 543,OR：18. 813, P=0. 046）were identified as independent influencing factors for the occurrence of bladder spasms after kidney transplantation（P<0. 05）. Conclusions Renal transplant patients have a longer preoperative dialysis time, and the use of harder urinary catheter materials and lower postoperative urine output can increase the risk of postoperative bladder spasms. Therefore, it is necessary to increase nursing evaluation for high-risk patients with bladder spasms mentioned above, monitor postoperative urine output, and choose soft urinary catheters as much as possible to prevent the occurrence of bladder spasms after kidney transplantation.

       目的   探讨女性医务人员月经改变的影响因素及与心理状态的相关性。方法   对深圳市3家医院女性医护人员进行随机抽样得到869份问卷调查样本，均为知情自愿参与本项调查研究。统计女性医务人员出现女性月经改变的比率和月经改变的基本特征，并采用单因素和多因素分析的方法分析影响月经改变因素。并以抑郁症筛查量表（PHQ-9）评估女性医护人员的心理状态，分析女性医务人员月经改变与心理状态评分间相关性。结果  869名女性医护人员中有293例发生月经改变，改变率为33.72%，其中月经周期改变94例、经期时间改变86例、月经量改变68例、痛经改变45例。将869例女性医护人员分为月经正常组和月经改变组，经单因素分析，两组间的年龄、职业、值夜班频率、既往病史、新冠感染等比较差异无统计学意义（P＞0.05）。月经改变组的护士占58.36%高于月经正常的24.48%，月经改变组的新冠一线抗疫人员占64.51%高于月经正常的27.08%，月经改变组合并妇科疾病史的占比20.82%（61例）高于月经正常组的占比11.98%（69例）。而月经改变组的护士、新冠一线抗疫人员、合并妇科疾病史、新冠感染的比较差异有统计学意义（P＜0.05）。多因素分析显示，职业为护士、合并妇科疾病史、新冠一线抗疫人员的P值分别为0.001、0.004、＜0.001，故而职业为护士、合并妇科疾病史、新冠一线抗疫人员是女性医务人员月经改变的危险因素。月经改变组PHQ-9评分为9.10±2.57，月经正常组PHQ-9评分为5.98±1.06，月经改变组PHQ-9评分高于月经正常组（P＜0.001）。两组受试者PHQ-9评分比较差异具有统计学意义，月经改变组PHQ-9评分中0～4分受试者为26.3%，月经正常组为47.2%，月经改变组PHQ-9评分中0～4分者比例小于月经正常组，差异具有统计学意义（P＜0.05）。结论   女性医务人员中职业为护士、合并妇科疾病史、新冠一线抗疫人员是月经改变的主要危险因素，且月经改变与心理状态有密切的相关性，需引起医疗机构的关注。

      Objective  To analyze the influencing factors of menstruation changes of female medical staff and the correlation with their psychological status．Methods  The female medical staff in three hospitals of Shenzhen were  randomly sampled to get 869 questionnaires，with informed and willing to participate in this research．The rate of female menstruation changes and the basic characteristics of menstruation changes in female medical staff were calculated，and the influencing factors of menstruation changes were analyzed by single factor and multi factor analysis．And the psychological status of female medical staff was using the Depression Screening Scale （PHQ-9），and the correlation between menstrual changes and psychological status scores of female medical staff were analyzed．Results  Among 869 female medical staff，293 had hemorrhagic menstrual disease，with a change rate of 33.72%．Among them，94 had changes in menstrual cycle，86 had changes in menstrual period days，68 had changes in menstrual volume，and 45 had changes in dysmenorrhea．These 869 female medical staff were divided into normal menstruation group and menstrual change group．Through single factor analysis，there was no statistical difference between the two groups in terms of age，careers，night shift frequency，previous medical history，COVID-19 infection （P＞0.05）．The percentage of nurses in the menstrual change group was 58.36%，higher than that of 24.48% in the normal menstruation group．The percentage of frontline medical staff combating COVID-19 in the menstrual change group was 64.51%，higher than that of 27.08% in the normal menstruation group．And the percentage of menstrual change group with a history of combined gynecological diseases was 20.82% （61 cases），higher than that of the normal menstruation group was 11.98% （69 cases）．And the difference was statistically significant when comparing the ratio of nurses，the frontline medical staff combating COVID-19，the history of gynecological diseases，and COVID-19 infection in the menstrual change group （P＜0.05）．Multivariate analysis showed that the occupation of nurses，frontline medical staffs combating COVID-19，and history of gynecological diseases were the risk factors for menstrual changes．The PHQ-9  score of the menstrual change group was higher than that of the normal menstrual group，and the difference was statistically significant．Conclusions  The main risk factors for menstrual changes are nurses，frontline anti-epidemic staff，and women with gynecological disease history．Menstrual changes are closely related to mental status，attention from healthcare organizations．

       目的   探讨剖宫产后再次分娩阴道试产失败的影响因素。方法   选取2021年5月—2024年5月在枣庄市妇幼保健院分娩的138例有剖宫产手术史的足月妊娠产妇进行回顾性分析。所有产妇依照其阴道试产结果将成功阴道分娩的35例产妇分为成功组，将阴道试产失败中转剖宫产的103例产妇分为失败组。对比两组产妇的妊娠结局、孕期情况及围产期情况，最后采用多因素Logistic回归分析法分析剖宫产后再次分娩阴道试产失败的影响因素。结果   两组产妇子宫破裂、胎儿窘迫、产褥感染及产后出血等妊娠不良结局总发生率对比差异无统计学意义（11.43% vs 6.80%，χ ² =0.760，P=0.382 ＞0.05）；通过对比两组产妇孕期情况发现，失败组与成功组孕妇年龄、孕次、身高、孕前体质量、妊娠期合并症、分娩前体质量指数（BMI）比较差异无统计学意义（P＞0.05），失败组与成功组孕妇孕期体质量增长［（4.56±2.56）kg vs（12.45±3.24）kg］、分娩孕周［（39.46±1.25）周 vs（37.95±1.37）周］、阴道分娩史（8.57% vs 26.21%）、妊娠间隔时间［（2.74±0.35）年 vs（3.37±0.57）年］及瘢痕厚度［（4.51±0.56）mm vs（5.42±0.38）mm］，对比差异有统计学意义（t=3.497，P＜0.001；t=5.755，P＜0.001；χ ² =4.780，P=0.029；t=6.148，P＜0.001；t=10.764，P＜0.001）；通过对比两组产妇围产期情况发现，失败组与成功组新生儿性别、是否镇痛比例比较差异无统计学意义（P＞0.05），失败组与成功组孕妇产前新生儿估重［（3352.31±153.67）g vs（3046.25±141.68）g］、是否引产［60.00% vs 52.43%］、胎膜早破［11.43% vs 35.92%］、入院时是否临产［857% vs 27.18%］，对比差异有统计学意义（t=10.805，P＜0.001；χ ² =7.330，P=0.007；χ ² =7.500，P=0.006；χ ² =5.200，P=0.023）；以阴道试产情况作为因变量（失败=1，成功=0）纳入Logistic回归模型，结果显示，分娩孕周过晚、产前新生儿估重过高、引产及入院时未临产为剖宫产后再次分娩阴道试产失败的影响因素（P＜0.05）。结论   分娩孕周过高、产前新生儿估重过高、引产及入院时未临产为剖宫产后再次分娩阴道试产失败的独立影响因素，需针对分娩孕周、产前新生儿估重过高的剖宫产后再次分娩阴道试产产妇给予高度关注并采取相应措施进行干预，同时自然临产能够降低阴道试产失败风险，但针对具有引产指征的产妇，依然需要及时引产。

       Objective   To explore the influencing factors of vaginal trial delivery failure after cesarean section．Methods   A retrospective analysis was conducted on 138 full-term pregnant women with a history of cesarean section who gave birth in our hospital from May 2021 to May 2024．All women were divided into two groups according to the  results of their vaginal trial delivery．Based on their vaginal trial results，35 parturients who successfully delivered were divided into the successful group，and 103 parturients who failed vaginal trial delivery and transitioned to cesarean section were divided into the failed group．The pregnancy outcomes of postpartum women and the pregnancy and perinatal conditions were compared between the two groups，and multivariate Logistic  regression analysis was used to analyze the independent influencing factors of vaginal trial delivery failure after cesarean section．Results   There was no significant difference in the total incidence of adverse pregnancy outcomes such as uterine rupture，fetal distress，postpartum infection，and postpartum hemorrhage between the two groups of parturients （P＞0.05）．By comparing the pregnancy status of two groups of  pregnant women，it was found that there was no difference （P＞0.05）．The average weight gain during pregnancy of failure and successful group，gestational age，cases with vaginal delivery history，intervalbetween pregnancy and scar thickness，the contrast difference was significant （all P＜0.05） ．By comparing the perinatal situation of the two groups，there was no difference in the sex of fetus and analgesia receiving of parturients between the failed group and the successful group （P＞0.05），while there is difference in weight estimation，whether induced labour，premature  rupture of fetal membrane，whether admitted to hospital （all P＜0.05）．Vaginal trial delivery was set as the dependent variable （failure=1，success=0） and it was incorporated into the Logistic regression model．The results showed that high gestational age during delivery，high estimated weight of fetus before delivery，induction of labor，and non-labor upon admission were independent influencing factors for vaginal trial delivery failure after cesarean section （P＜0.05）．Conclusions  Excessive gestational age，high estimated weight of fetus before delivery，induced labor，and non-labor upon admission were independent influencing factors for the failure of vaginal trial delivery after cesarean section．It is necessary to pay high attention and take corresponding measures to intervene in women who have undergone vaginal trial delivery after cesarean section due to excessive gestational age and high estimated weight of fetus before delivery．At the same time，spontaneous labour can reduce the risk of vaginal trial delivery failure．However，for women with indications for induced labor，timely induction is still necessary．
