Objective: To investigate the current status and influencing factors of sleep disorders among pregnant women, so as to provide insights into health management during pregnancy. Methods: Pregnant women who underwent prenatal checkups at Hangzhou Obstetrics and Gynecology Hospital from January to October 2023 were selected as subjects, and general data including age, pregnancy period and exercise were collected through questionnaire surveys. Sleep quality, pregnancy stress, anxiety and depression were evaluated using Pittsburgh Sleep Quality Index, Pregnancy Stress Rating Scale, Pregnancy-related Anxiety Scale and Edinburgh Postnatal Depression Scale, respectively. Factors affecting sleep disorders among pregnant women were analyzed using a multivariable logistic regression model. Results: A total of 386 pregnant women was surveyed, with a mean age of (30.28±4.65) years, including 20.47% in the first trimester, 47.93% in the second trimester and 31.61% in the third trimester. Women with anxiety and depression accounted for 14.51% and 21.76%, respectively. Pregnancy stress was mainly moderate, accounting for 51.04%. There were 106 pregnant women with sleep disorders, accounting for 27.46%. Mutivariable logistic regression analysis showed that age (≥35 years, OR=1.656, 95%CI: 1.094-2.503), pregnancy period (third pregnancy, OR=2.097, 95%CI: 1.213-3.621), regular exercise in the past 6 months (OR=0.376, 95%CI: 0.210-0.670), anxiety (OR=2.794, 95%CI: 1.545-5.048), depression (OR=3.501, 95%CI: 1.877-6.529) and pregnancy stress (moderate, OR=1.355, 95%CI: 1.018-1.801; severe, OR=2.538, 95%CI: 1.417-4.540) were the factors affecting sleep disorders among pregnant women. Conclusions Sleep disorders of pregnant women is influenced by age, pregnancy period, pregnancy stress, anxiety, depression and exercise. It is necessary to identify high-risk individuals with sleep disorders early, and to provide psychological intervention and prenatal health guidance.

Objective To explore and analyze the clinical efficacy and effects of the application of dexmedetomidine in the tube drawing period of general anesthesia for the patients receiving laparoscopic surgery. Methods Sixty-eight pa-tients who received laparoscopic surgery in our hospital from December 2012 to December 2013 were selected as the study subjects and randomly divided into the control group and the study group. By the end of surgery, the patients were transferred to the post-anesthesia care unit (PACU) with catheter and different anesthetic drugs were used. The control group received target controlled infusion of propofol and the study group received dexmedetomidine. Results The four groups of patients were different in MAP and BIS at T2, T3, T4 and T5, with statistically significant differ-ences (P<0.05). Regarding to VAS scores and adverse reactions, group A2 and group A3 were different from the control group respectively, with significant differences (P<0.05). Conclusion The application of dexmedetomidine in the tube drawing period of general anesthesia after laparoscopic surgery for the purpose of analgesia and sedation is conducive to maintaining hemodynamic stability, relieving postoperative pain and reducing the incidence of postoperative complica-tions.

Objective To observe and analyze the clinical analgesic anesthesia effect of propofol combined with pare-coxib sodium for the patients receiving bronchofiberscope examination. Methods Eighty-seven patients receiving bron-chofiberscope examination in our hospital from January 2012 to February 2014 were selected as the study subjects and randomly divided into group A, group B and group C. The three groups of patients received parecoxib sodium combined with propofol, propofol combined with fentanyl, and propofol respectively for preoperative anesthesia. The MAP and SPO2 changes, usage amount of anesthetic drugs, and awakening time of the three groups at different time were recorded, and the results were tabulated and analyzed. Results SpO2 of the three groups at different time did not change obvi-ously, with no significant differences (P>0.05). The three groups did not have statistically significant differences in the bronchofiberscope examination time (P>0.05). Group A had the lowest usage amount of anesthetic drugs and the short-est awakening time, which had statistically significant differences to the other two groups (P<0.05). Conclusion In analgesic bronchofiberscope examination, the application of propofol combined with parecoxib sodium for anesthesia and analgesia plays a positive role in increasing the patients' postoperative comfort sensation and postoperative living quality.

Objective To determine the expression of ubiquitin-conjugating enzyme E2S (UBE2S) in malignant melanoma (MM),and to evaluate its effect on the biological behavior of melanoma cells.Methods Immunohistochemical study was performed to determine the UBE2S expression in 128 primary MM tissue chips,64 metastatic MM tissue chips,16 non-tumor tissue chips (8 paralesional normal skin tissues and 8 normal epidermal tissues).Real-time quantitative RCR was conducted to determine the UBE2S mRNA expression in the melanoma cell lines A375,MUM-2B and MUM-2C.The melanoma cell lines A375 and MUM-2B were divided into 2 groups separately:interference group transfected with a lentiviral vector carrying UBE2S RNA interference sequence,and control group transfected with a lentiviral vector carrying control sequence.After 72 hours,real-time quantitative RCR was performed to determine the UBE2S mRNA expression in the melanoma cell lines A375 and MUM-2B.Caspase-3/7 activity in the groups was assessed by using kits,and cell apoptosis and cell cycle distribution were detected by flow cytometry.The effect of UBE2S knockdown on the migratory and invasive abilities of and N-cadherin expression in A375 cells were evaluated by Transwell assay and Western blot analysis respectively.Statistical analysis was carried out with SPSS 22.0 software by using independent sample t-test for the comparison of normally distributed data between two groups,chi-square test for enumeration data,MannWhitney U test for the comparison of non-normally distributed data,and Spearman's coefficient for assessment of the correlation of UBE2S expression with T staging of melanoma.Results UBE2S was highly expressed in 98 (51.0％) MM tissues,but lowly expressed in 16 non-tumor tissues,and the UBE2Sexpression rate significantly differed between the above two kinds of tissues (x2 =11.905,P ＜ 0.01).UBE2S expression was negatively correlated with T staging of melanoma (ρ =-0.210,P =0.043).The relative mRNA expression of UBE2S significantly differed among the A375,MUM-2B,and MUM-2C cells (F =817.228,P ＜ 0.01).After UBE2S knockdown,the caspase-3/7 activity was significantly up-regulated in the A375 interference group (t =17.572,P ＜ 0.01) and MUM-2B interference group (t =24.552,P ＜0.01) compared with the A375 and MUM-2B control groups respectively.Compared with the control group,the A375 interference group showed significantly increased proportion of A375 cells at G1 phase (t =7.365,P ＜ 0.01),decreased proportion at S phase (t =-9.190,P ＜ 0.01),and no change in the proportion of A375 cells at G2/M phase (t =-0.227,P ＞ 0.05).The MUM-2B interference group showed significantly increased proportions of MUM-2B cells at G1 (t =12.676,P ＜ 0.01) and G2/M phases (t =13.045,P ＜0.01),but significantly decreased proportion at S phase (t =-15.718,P ＜ 0.01) compared with the control group.Transwell assay revealed decreased migratory and invasive abilities of A375 cells in the interference group compared with the control group (t =-35.727,-125.000,P ＜ 0.05,＜ 0.01,respectively).Western blot analysis showed down-regulated expression of N-cadherin protein in A375 cells in the interference group compared with the control group.Conclusions UBE2S is over-expressed in melanoma tissues,whose expression is associated with the T staging of melanoma.Knockdown of UBE2S affects the apoptosis,cell cycle,migration and invasion of melanoma cells,and may promote the metastasis of MM cells by regulating N-cadherin expression.

Objective:To discuss the influencing factors of neonatal scalp hematoma, and provide a basis for reducing the occurrence of neonatal scalp hematoma.Methods:Retrospectively analyzed the data of 13 151 parturients and their newborn infants who delivered in the Hangzhou Women′s Hospital from January to December 2020, counted the incidence of neonatal scalp hematoma, and Logistic regression analysis was used to analyze its influencing factors.Results:Among 13 151 newborn baby, 68 cases of neonatal head hematoma occurred, the incidence was 0.52%. Vaginal delivery, forceps, intraspinal analgesia were statistically significant in the occurrence of neonatal scalp hematoma ( χ2=19.26, 19.59, 6.11, all P<0.05). Conclusions:Vaginal delivery, forceps, and intraspinal analgesia are the risk factors for neonatal scalp hematoma. Lateral perineal incision during delivery did not reduce the incidence of neonatal scalp hematoma. In this study, many cases of neonatal scalp hematoma occurred before the crown of the fetal head. Labor management, improve the rate of non-drug analgesia, promote natural delivery, early detection, early prevention, and reduce the incidence of neonatal hematoma.

Objective:To investigate the efficacy and safety of high semi-decubitus position in the second stage of labor in epidural analgesic delivery of primipara.Methods:A total of 120 women who gave birth in Hang-zhou women's Hospital from May 1,2021 to July 30,2021 were randomly divided into experimental group(n=60)and control group(n=60)by random number table method.The control group adopted supine position in the sec-ond stage of labor,and the experimental group transferred to high semi-supine position after the supine position was used applied for 30 minutes when the fetal head was not exposed.To compare the effects of different postur-al positions on the duration of the second stage of labor,mode of delivery,postpartum injury,perineal tearing,la-bor force experience and labor control,and neonatal asphyxia.Results:The duration of uterine opening to fetal head exposure,the duration of uterine opening to fetal head crown and the duration of second stage of labor in experimental group were shorter than those in control group.The rate of natural delivery of experimental group was higher than that of control group.The episiotomy rate and the second degree perineal laceration rate were lower than that of control group.The amount of blood loss during delivery and 2h postpartum of experimental group was less than that of control group.The scores of birth experience and birth control of experimental group were higher than those of control group,and the differences were statistically significant(P＜0.05).There was no significant difference in 1-minute Agpar score and 5-minute Agpar score between the two groups(P＞0.05).Conclusions:The application of high semi-decubitus position under epidural labor analgesia promoted vaginal natural labor,shortened the time of second stage of labor,reduced episiotomy rate and perineal laceration de-gree,reduced postpartum hemorrhage,had positive labor force experience,and increased the sense of labor con-trol.

Objective:To investigate clinicopathological features of hypopigmented mycosis fungoides (HMF) and hypopigmented interface T-cell dyscrasia (HITCD) .Methods:A total of 41 patients with cutaneous hypopigmented lymphoproliferative diseases, who had complete clinicopathological data, were collected from Department of Dermatology, the Third People′s Hospital of Hangzhou from January 2015 to September 2020, and the clinicopathological and immunophenotypic features were analyzed. Comparisons of normally distributed measurement data were carried out using t test, comparisons of categorical data using Chi-square test or Fisher′s exact test, and comparisons of ranked data between 2 groups using rank-sum test. Results:All of the 41 patients clinically presented with irregular hypopigmentation, some of which was accompanied by erythema or furfuraceous scales. In terms of pathological features, 21 patients showed infiltration and aggregation of atypical lymphoid cells in the epidermis, which was consistent with typical pathological features of mycosis fungoides, and they were diagnosed with HMF; 20 patients showed vacuolar degeneration of the basal layer, accompanied by infiltration of lymphoid cells and mild epidermotropism, and they were diagnosed with HITCD. All immune cells expressed T-cell phenotype, and epidermal lymphocytes expressed a CD8-dominated phenotype in 14 (67%) cases of HMF and 13 (65%) of HITCD. In the epidermis, the total number of lymphocytes was significantly higher in the HMF group than in the HITCD group ( t= 1.81, P= 0.012) ; in the dermis, the number of CD4 + lymphocytes and CD8 + lymphocytes, and the total number of lymphocytes were all significantly higher in the HMF group than in the HITCD group ( t= 2.64, 1.51, 2.60, P= 0.012, 0.002, 0.001, respectively) . All patients were treated with narrow-band ultraviolet B radiation. Among 34 patients who completed the follow-up, 30 achieved complete clearance of skin lesions without recurrence, including all patients with HITCD, and 4 with HMF achieved partial regression of the lesions. Conclusions:Compared with HMF, HITCD presents different pathological characteristics and benign biological behaviors. Thus, HITCD should be distinguished from HMF as an independent disease. Phototherapy alone is effective for the treatment of HITCD.

Objective:To analyze consistency between histopathological and reflectance confocal microscopy (RCM) characteristics of early-stage mycosis fungoides (MF) , and to evaluate the value of RCM in assisting the pathological diagnosis of early-stage MF and the feasibility of dynamic monitoring of treatment response with RCM.Methods:From January 2014 to January 2018, 40 cases of clinically suspected MF were collected from Department of Dermatology, Third People′s Hospital of Hangzhou, including 26 males and 14 females, and their age was 47.0 ± 17.6 years. According to the summarized RCM characteristics of early-stage MF, biopsy sites were preliminarily located, and then a histopathological examination was performed. The RCM and pathological features of MF were compared. In addition, a combination therapy with narrowband ultraviolet B and interferon was performed in patients with confirmed MF. Targeted lesions were followed up with RCM for 9 months, and then therapeutic efficacy was evaluated.Results:Among the 40 cases of clinically suspected MF, 8 were preliminarily diagnosed as typical MF, 18 as suspected MF, and 14 were excluded according to the RCM characteristics; according to the pathological features, 12 could be diagnosed as typical MF, 14 as suspected MF, and 14 were excluded. Consistency analysis showed that the kappa coefficient between RCM classification and pathological diagnosis was 0.848 ( P < 0.01) . The consistency of epidermal infiltration of mildly refractive cells was the highest between RCM and pathological findings (kappa coefficient = 1, P = 0.005) , followed by dermal fibrosis at the erythema stage (kappa coefficient = 0.714, P = 0.035) . The RCM characteristics of MF gradually returned to normal during treatment, but atypical lymphocytes still existed when clinical lesions completely regressed. Conclusion:RCM can be used for pathological localization of suspected MF lesions in the early stage, and for dynamic monitoring of therapeutic efficacy in MF.
