Objective To assess the clinical value of multimodal ultrasound score for assessment of endometrial receptivity among patients with polycystic ovary syndrome (PCOS), and to provide guidance for improving pregnancy outcomes among PCOS patients. Methods A total of 48 PCOS patients admitted to Jiangning Hospital Affiliated to Nanjing Medical University between January and December 2023 were enrolled as the case group, while 50 healthy women of childbearing age received ovulation monitoring at the same hospital during the same period served as the control group. Subjects received two-dimensional grayscale ultrasound during the implantation window (19 to 23 days of the menstrual cycle) for measurement of endometrial thickness, Gonen classification, and endometrial peristalsis. Two-dimensional color Doppler ultrasound was used for assessment of endometrial blood flow and three-dimensional ultrasound was used for assessment of endometrial volume and vascularization flow index (VFI). The endometrium multimodal ultrasound scores were estimated, and various parameters were compared between the two groups. The diagnostic performance of these parameters for PCOS was evaluated with receiver operating characteristic (ROC) curves. Results The age of subjects in the case group ranged from 20 to 38 years, with a mean age of (28.20 ± 2.82) years, and their body mass index (BMI) ranged from 21.23 to 29.11 kg/m², with a mean BMI of (26.25 ± 1.60) kg/m². The age of subjects in the control group ranged from 22 to 38 years, with a mean age of (28.10 ± 1.99) years, and their BMI ranged from 21.33 to 29.03 kg/m², with a mean BMI of (26.10 ± 1.78) kg/m². There were no significant differences between the case and control groups in terms of mean age, BMI, estradiol, and testosterone (t = 0.218, 0.422, 0.010, and 0.221; all P > 0.05). The endometrial thickness, endometrial volume, and VFI were significantly higher in the control group than in the case group (t = 4.838, 4.978, and 7.115; all P < 0.05). There were significant differences between the two groups in terms of endometrial classification, endometrial peristalsis pattern, and endometrial and sub-endometrial blood flow (Z = −4.136, −4.048, and −3.884; all P < 0.05). The scores of endometrial classification, endometrial peristalsis, endometrial and sub-endometrial blood flow, endometrial volume, VFI, and multimodal ultrasound were significantly lower in the case group than in the control group (t = 4.539, 4.449, 4.205, 3.209, 5.206, and 4.495; all P < 0.05). No significant difference was detected in the endometrial thickness score between the two groups (t = -0.149, P = 0.882). The areas under the ROC curves for endometrial thickness, endometrial volume, VFI, and multimodal ultrasound scores in diagnosis of PCOS were 0.753, 0.747, 0.809, and 0.858, respectively. Conclusion Multimodal ultrasound score provides a comprehensive assessment of the endometrium, and is effective in the assessment of endometrial receptivity, which may provide a reference for guiding pregnancy planning in PCOS patients.

Abstract: Objective　To compare and analyze the clinical characteristics, diagnosis, and treatment of different subtypes of severe influenza in neonates to provide a reference for the diagnosis and treatment of neonatal severe influenza. Methods A cohort of 40 neonates with severe influenza who were hospitalized in the neonatology ward of Children's Hospital Affiliated to Zhengzhou University between January 2019 to December 2023 were selected and divided into two groups based on the virus subtype: influenza A (n=23) and influenza B (n=17). A retrospective analysis was conducted to compare general information, clinical manifestations, auxiliary examinations, complications, and treatment outcomes of neonates with severe influenza A and B infection. Results The number of days of hospitalization was longer in cases of influenza A than that of influenza B. The proportion of neonates with severe influenza A who exhibited fever was higher than that for influenza B, and a higher percentage of those with fever had peak temperatures ranging from 38.1 ℃ to 39 ℃. Gastrointestinal symptoms, including vomiting and diarrhea leading to dehydration, were more evident in severe influenza B cases. The proportion of influenza A cases with abnormal creatine kinase-MB isoenzyme levels (>25 U/L) was higher than that of influenza B, and the differences were statistically significant (P<0.05). There were no significant differences between the two types of influenza in other clinical manifestations, the incidence of pneumonia/respiratory failure complications, peripheral blood leukocyte count and classifications, the proportion of abnormal aspartate aminotransferase (AST) (>40 U/L), alanine aminotransferase (ALT) (>40 U/L), and creatine kinase (CK) (>200 U/L), and lactate dehydrogenase (LDH) values (all P>0.05). In terms of treatment, neonates treated with Oseltamivir within 48 hours of onset mainly suffered from influenza A. Among those treated with Oseltamivir, the proportion of influenza A cases whose body temperature returned to normal within 24 hours was relatively higher, whereas, for those whose temperature returned to normal within 24-72 hours, the proportion was relatively higher in influenza B cases. These differences were statistically significant (all P<0.05). Conclusions Severe neonatal influenza usually occurs in winter and spring. After severe infection, fever is more obvious in neonates with influenza A, which is more likely to cause myocardial cell damage. Neonates with influenza A can be treated with Oseltamivir earlier and return to normal body temperature faster than those with influenza B after Oseltamivir treatment. Gastrointestinal symptoms are more common in neonates with severe influenza B.

Objective:To investigate the clinical effect and short-term and long-term effect of total hip replacement (THA) and hemiarthroplasty of hip (HA) in elderly patients with femoral neck fracture (FNF).Methods:59 elderly patients with FNF in South District of Guang′anmen Hospital, Chinese Academy of Traditional Chinese Medicine from March 2017 to January 2019 were retrospectively analyzed. The observation group ( n=29) was treated with THA; The control group ( n=30) was treated with HA. The operation related indexes, short-term and long-term clinical effect (average follow-up of 24.1 months), hip function improvement, pain and complications were compared between the two groups. Short term and long-term clinical effects: the short-term and long-term clinical effects of the two groups were observed by the Harris Hip Score (HHS) of the first month, the third month, the sixth month, the ninth month and the first year after operation. Results:Both THA and HA were effective on elderly FNF, but the effective rate of THA (96.6%) was significantly higher than that of HA (90.0%), with statistically significant difference ( P<0.05); in terms of operation related indicators, compared with the control group, the observation group had longer operation time [ (104.46±3.24)min vs (84.34±3.64)min], more amount of bleeding [(296.64±15.16)ml vs (281.44±12.16)ml], lower postoperative drainage volume [(101.24±4.15)ml vs (74.56±3.24)ml], while the functional recovery of the observation group was better than the control group by HHS ( P<0.05); the postoperative complications and HHS score of observation group were significantly lower than the control group ( P<0.05). Conclusions:THA has the advantages of low complication, fast functional recovery and better effect. The clinical decision should be based on the patient′s physical condition. THA should be used for elderly patients with good basic condition, good surgical tolerance and more daily activities. HA should be used for elderly patients with poor basic condition, low surgical tolerance and less daily activities.

Background Studies have shown that stress during pregnancy can affect the growth and development of fetuses and offspring, and this effect has sex differences, but the results are controversial, and there are few studies on the emotional damage of offspring of different sexes caused by stress during pregnancy. Objective This experiment is designed to observe the effect of chronic stress during pregnancy on emotional damage of offspring of different sexes. Methods Thirty-two SD female rats were randomly divided into a model group and a control group (16 rats in each group), 24 male rats were divided into a model mating group (n=16) and a control mating group (n=8). Each rat of the model group was reared in a single cage and received chronic unpredictable mild stress (CUMS) for 28 d, including hot water swimming for 5 min, cold water swimming for 5 min, tail pinching for 2 min, crowding for 24 h, moist bedding for 24 h, cage shaking for 30 min, and space restriction for 2 h. One stressor was administered daily and the same stressor did not repeat within 7 d. Blood was collected from the endocanthal vein of the two groups of female rats 1 d before and 1, 7, 14, 21, and 28 d after stress, the plasma was separated by centrifugation, and ¹³¹I radioimmunoassay was used to measure plasma corticosterone concentration. On postnatal day 21 (PND21), 16 offspring rats (half male and half male) were randomly selected from each group, their plasma corticosterone concentration was measured on PND28 and PND42, and their emotional damage was measured on PND42. Results The plasma corticosterone levels of dams in the model group on the 14th, 21th, and 28th days of stress [(394.02±97.40), (444.12±90.43), and (463.71±107.75) μg·L⁻¹] were higher than those in the control group [(285.63±81.64), (341.78±48.39), and (320.42±84.76) μg·L⁻¹] (all P< 0.05). On PND28 and PND42, the plasma corticosterone levels in the female model offspring group [(543.30±90.21) and (530.76±83.10) μg·L⁻¹] were higher than those in the female control offspring group [(397.77±64.27) and (325.78±61.03) μg·L⁻¹] (both P<0.05). In the sugar water preference test, the total fluid consumption [(10.74±1.28) mL], sugar water consumption [(5.50±1.30) mL], and 1% sucrose preference percentage [(20.36±3.41) %] in the female model offspring group were lower than those in the female control offspring group [(13.74±2.06) mL, (8.56±2.04) mL, and (62.11±8.05) %] (all P<0.05). In the open field test, the horizontal score, vertical score, and cleaning times of the male model offspring group were lower than those of the male control offspring group (all P<0.05). In the tail suspension test, the immobility time of the female and male model offspring groups [(126.95±39.88) and (70.24±28.98) s] was longer than the control offspring groups of the same sex [(54.30±24.99) and (38.63±18.91) s] (both P<0.05), and the duration of immobility time in the female model offspring group was longer (t=3.253, P=0.006). In the forced swimming test, the immobility time of the female model offspring group [(7.97±6.66) s] was longer than that of the female control offspring group [(1.85±2.12) s] (t=2.478, P=0.037). On PND42, the plasma corticosterone level of female offspring was negatively correlated with total fluid consumption, sugar water consumption, and 1% sucrose preference percentage (r=−0.621, r=−0.728, r=−0.699; P<0.05), and positively correlated with immobility time in the tail suspension test and immobility time in the forced swimming test (r=0.571, r=0.712; P<0.05), However, there was no correlation between plasma corticosterone and emotional indicators on PND42 in male offspring (P>0.05). Conclusion Chronic stress during pregnancy causes emotional damage to the offspring, and female offspring show depression-like behaviors.

Objective To investigate the significance of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in serum and cerebrospinal fluid for evaluation of severe hand ,foot ,and mouth disease (HFMD) complicated with neurogenic pulmonary edema (NPE).Methods A total of 140 patients diagnosed with HFMD in Henan Children′s Hospital were enrolled and divided into three groups including mild group ,severe HFMD group without NPE ,severe HFMD group with NPE .These severe HFMD patients were also divided into survival group and death group according to the 28-day prognosis .Meanwhile ,50 age-matched healthy children were selected as controls .Serum MMP-9 and TIMP-1 levels were measured in all enrolled children .At the same time ,MMP-9 ,TIMP-1 and ratio of MMP-9／TIMP-1 in cerebrospinal fluid were measured in the severe HFMD group with and without NPE .Quantitative data were compared using one-way analysis of variance , and means comparisons between samples were conducted using LSD-t test .Results Among 140 children with HFMD ,66 were in mild group ,42 in severe HFMD without NPE group ,and 32 in severe HFMD with NPE group .And 50 healthy children were in control group .After 28 days ,14 cases died in severe HFMD groups .MMP-9 , TIMP-1 and MMP-9／TIMP-1 in serum of severe HFMD group with NPE increased significantly greater than those in the other three groups (F＝269 .356 ,121 .301 and 101 .502 ,respectively ,all P ＜0 .05). MMP-9 ,TIMP-1 and MMP-9／TIMP-1 in cerebrospinal fluid of severe HFMD group with NPE were (57 .24 ± 8 .92) μg／L ,(35 .26 ± 8 .14) μg／L and (1 .66 ± 0 .23) μg／L ,respectively ,while those in cerebrospinal fluid of severe HFMD group without NPE were (30 .57 ± 3 .89) μg／L ,(26 .25 ± 0 .32) μg／L and (1 .17 ± 0 .61) μg／L ,respectively .The differences between the two groups were all statistically significant (t＝62 .485 ,37 .680 and 169 .387 ,respectively ,all P＜0 .01).MMP-9 ,TIMP-1 and MMP-9／TIMP-1 in serum and cerebrospinal fluid of death group increased significantly greater than those in survival group ,the difference were statistically significant (all P＜0 .01).The maximum area under curve (AUC) was reached when the MMP9／TIMP-1 ratio in cerebrospinal fluid was 0 .890 (95% CI :0 .801 －0 .978).Conclusions MMP-9 and TIMP-1 may be involved in the pathogenesis of HFMD complicated with NPE .The detection of MMP-9 and TIMP-1 levels may be beneficial for the early diagnosis of severe HFMD with NPE .The imbalance of MMP-9／TIMP-1 ratio can be used as one of the predictors of severe HFMD combined with NPE.
