ObjectiveTo find out whether there is any difference in the monitoring results of mosq-ovitraps placed in different orientations in multi-storey residential areas, so as to provide a scientific basis for routine and emergency monitoring of Aedes albopictus with mosq-ovitraps in residential areas. MethodsFrom July 6th to October 26th 2023, one mosquito ovitrap was set up in each of the 4 orientations of east, south, west and north around the buildings in a multi-storey residential area in Jinhui Town, Fengxian District, Shanghai. Data was collected and recorded 72 hours after placement. The chi-square test was used to compare the mosquito ovitrap indices (MOIs) of two independent samples, and the Kruskal⁃Wallis H test was used to compare the MOIs of multiple independent samples. ResultsAfter 16 weeks of surveillance, 997 mosquito ovitraps were recovered, of which 211 were positive, with the mosquito ovitrap index (MOI) of 21.16% and the Aedes albopictus density index of 1.03 mosquitoes·ovitrap^-1. The MOIs were higher in September (24.22%) and October (23.96%), and the MOIs in the west, south and north within the two months were all above 20.00%. From July to October, the MOIs in the east, west, south and north were 20.70%, 22.20%, 25.50% and 16.20%, respectively, and the difference in MOIs among the 4 orientations was not statistically significant (χ²=6.647, P=0.084). Stratified analysis by month showed that in August, the south side of the multi-storey residential areas had the highest MOI (31.30%), the north side had the lowest MOI (1.30%), and there was a statistically significant difference in MOI in the east, west, south and north (χ²=25.986, P<0.001). In October, the MOI in the west was the highest (33.30%) and the MOI in the east was the lowest (6.30%), the difference in MOIs of the 4 orientations was statistically significant (χ²=12.007, P=0.007). The MOIs in the south side of the building in the outskirts of the residential area from the 1st week in July to the 4th week in October was lower (19.20%) than that in the south side of the inner building (31.70%), and the difference in MOI was statistically significant (χ²=5.118, P=0.024). ConclusionThe study of MOI in different orientations in a multi-storey residential area is a preliminary exploration based on field work, and the results show that there is a difference in MOIs in different orientations during the peak breeding period of mosquitoes. Further indicators such as temperature, humidity and wind speed in different orientations can be collected to explore the influencing factors of MOIs.

Objective: To explore the moderating role of estradiol in the relationship between parenting styles and preschool children's behavioral problems, so as to provide a theoretical basis for improving the development of human s emotional health development in early life stage. Methods: During September to November in 2022, 354 children aged 3-6 years and their parents from two kindergartens in Bengbu City were chosen by using stratified cluster sampling method for the questionnaire survey. The Parenting Style Scale and the Child Behavior Checklist (CBCL) were used to collect information on parenting style and child behavioral problems. Salivary estradiol of children was collected and tested. Independent samples t test was applied to compare the scores of the scale for parental up bringing and children s behavioral problems, and Pearson correlation analysis was conducted to explore the relationship among parental upbringing, estradiol and children s behavioral problems. Results: Parents doting, laissez faire, autocratic, and inconsistent parenting styles were positive associated with child behavior problems( r =0.14-0.70); fathers democratic parenting style was negatively associated with child behavior problems( r =-0.14，-0.22，-0.21，-0.17，-0.27，-0.20); mothers democratic parenting styles was negatively correlated with scores on all five dimensions of child behavior problems except the withdrawal dimension ( r =-0.14，-0.12，-0.13，-0.21，-0.12)( P <0.05). Estradiol levels had significant moderating effects on maternal doting parenting style and children s withdrawal ( β =0.68) as well as social problems ( β =-1.00), also moderating laissez faire parenting styles and children s withdrawal problems ( β =0.75)( P <0.05). For children with low levels of estradiol, withdrawal problem scores were negatively associated with mother s doting parenting style and positively associated with laissez faire parenting style, and socialization problem scores were associated with mother s doting parenting style; for children with high levels of estradiol, withdrawal problem scores were positively associated with mother s doting parenting style, and socialization problem scores were associated with mother s doting parenting style ( t=2.84, 6.24, 3.16 , 2.37, 4.49, P <0.05). Conclusions Parenting styles are strongly associated with child behavioral problems; estradiol levels play a moderating role in mothers doting, laissez faire parenting styles and children s withdrawal problems and social problems.Parents should adopt more positive parenting styles and focus on the role of estradiol levels in maternal education to reduce the occurrence of behavioral problems in children.

To investigate the initial experience of coated metal ureteral stent(CMUS)for treatment of pelvic lipomatosis induced hydronephrosis(PLH).The clinical and follow-up data of 8 patients who were diagnosed as PLH treated with CMUS in Peking University People's Hospital from August 2018 to February 2021 were retrospectively analyzed.Inclusion criteria included:Imaging evidence of excessive adipose tissue around the bladder in the pelvic cavity,bladder elevation in an"inverted pear shape",and bladder wall thickening;Cystoscopy indicated follicular hyperplasia of bladder mucosa and biopsy pathology indicated glandular cystitis;Unilateral or bilateral hydronephrosis and ureteromegaly.Exclusion criteria included:Ureteral atresia;Recurrent obstruction of the bladder outlet.Preoperative baseline data included age,gender,serum creatinine,pelvis width and ureteric stent symptoms questionnaire(USSQ)score.Intraoperative data included the location and length of ureteral stenosis observed by retrograde urography.Postoperative follow-up data included serum creatinine,pelvis width,and USSQ score.In the study,8 patients(11 sides)with PLH were all male,with an average age of(38.7±8.6)years.Uni-lateral hydronephrosis was found in 5 cases and bilateral hydronephrosis in 3 cases.Preoperative mean serum creatinine was(90.0±10.3)μmol/L,and the mean renal pelvis width was(3.0±1.5)cm.The lower ureteral stricture was found in all cases,and the mean stricture length was(1.9±0.9)cm.Before operation,3 patients had ureteral Double-J stents,with USSQ scores of 97.0,68.0 and 100.0,respectively.Five patients underwent retrograde CMUS stenting,and 3 patients retrograde and antegrade.At the last follow-up,the average serum creatinine was(82.0±11.1)μmol/L and the mean renal pel-vis width was(1.9±0.5)cm,which were significantly lower than those before operation(t=3.12,P=0.02;t=3.23,P=0.02).In the 3 patients with Double-J stent before surgery,the USSQ scores were 87.0,62.0 and 89.0,respectively,which were significantly improved after CMUS stenting.The average follow-up time was(10.0±6.3)months.During the follow-up,1 patient developed CMUS re-lated symptoms,and no stent-associated infection and stent encrustation were found.In one case,the stent migrated to the bladder 3 months after operation,and the hydronephrosis disappeared after 3 months follow-up.CMUS stenting for treatment of PLH has certain efficacy and safety,which can explore a new therapeutic method for the long-term treatment of PLH.

OBJECTIVE: To assess health related quality of life (HRQOL) in patients with kidney stones and to predict risk factors for reduced HRQOL in the patients by the Chinese version of Wisconsin stone quality of life questionnaire (C-WISQOL). METHODS: The patients with renal stones admitted to Peking University People ' s Hospital from July 2020 to June 2021 were prospectively enrolled. The inclusion criteria included the patients with renal stones aged 18-80 years and sufficient Chinese language foundation, and the exclusion criteria included the patients with internal ureteral stents, malignant tumors, sepsis, etc. Demographic data and clinical data related to kidney stones were collected, and the C-WISQOL and the short form 36 health survey (SF-36) questionnaire completed by the patients was recorded. C-WISQOL included four domains (D): emotional impact (D1), social impact (D2), stone-related impact (D3) and vitality impact (D4). Cronbach ' s α coefficient was used to verify the internal consistency of C-WISQOL, Spearman ' s rho coefficient was used to verify the criterion validity between C-WISQOL and SF-36 questionnaire, confirmatory factor analysis was used to verify the structural validity, convergent validity and discrimination validity of C-WISQOL, and univariate and multivariate analyses were used to explore the risk factors leading to the decline of HRQOL in the patients with kidney stones. RESULTS: The study included 307 patients with kidney stones, of whom 212 (69.1%) were male, with a mean age of (51.9±13.5) years, and a mean body mass index (BMI) of (25.4±3.6) kg/m². 160 (52.1%) patients were complicated with metabolic syndrome (MS), 202 (65.8%) had history of calculi, 217 (70.7%) had calculi related symptoms, 53 (17.3%) had bilateral renal calculi, 82 (26.7%) had ureteral calculi, 199 (64.8%) had hydronephrosis, 78 (25.4%) had renal insufficiency, and urinary tract infection (UTI) was found in 168 patients (54.7%) with an average diameter of (15.6±5.9) mm. The mean total score of C-WISQOL questionnaire for all the patients was (94.9±13.7) points, D1 was (27.2±4.2) points, D2 was (23.8±3.7) points, D3 was (27.0±3.6) points, and D4 was (10.1±1.9) points. The Cronbach ' s α coefficient of the total score of C-WISQOL questionnaire was 0.968 and the four dimensions ranged from 0.860 to 0.898. The Spearman' s rho co- efficient between C-WISQOL and SF-36 total score was 0.564, and the Spearman' s rho coefficient between dimensions was 0.684-0.901, indicating that C-WISQOL had good internal consistency and criterion validity. Confirmatory factor analysis showed that C-WISQOL had good structural validity, convergent validity and discrimination validity. Univariate analysis showed that the patients with MS (OR=1.607, P < 0.001), calculi related symptoms (OR=1.268, P < 0.001), bilateral kidney stones (OR=1.900, P < 0.001), combined with ureteral calculi (OR=1.018, P < 0.001), accompanied by hydronephrosis (OR=1.685, P < 0.001), and UTI (OR=1.275, P < 0.001) were risk factors for decreased HRQOL in the patients with kidney stones, and multivariate analysis showed that the patients with MS (OR=1.475, P < 0.001), calculi related symptoms (OR=1.546, P=0.043) and UTI (OR=1.646, P=0.005) were independent risk factors for HRQOL decline in the patients with renal calculi. The t-test results showed that C-WISQOL scores were significantly higher in the patients without MS, stone-related symptoms and UTI than those in the patients with associated risk factors (P < 0.001). CONCLUSION C-WISQOL the questionnaire can be used to evaluate the HRQOL of patients with kidney stones with good reliability. The combination of MS, stone-related symptoms and UTI were independent risk factors for HRQOL reduction in the patients with renal stones.

BACKGROUND: Extreme temperature events, including extreme cold, are becoming more frequent worldwide, which might be harmful to pregnant women and cause adverse birth outcomes. We aimed to investigate the association between exposure to low ambient temperature in pregnant women and adverse birth outcomes, such as preterm birth, low birth weight, and stillbirth, and to summarize the evidence herein. METHODS: Relevant studies were searched in PubMed, Cochrane, and Embase electronic databases until November 2021. Studies involving low ambient temperature, preterm birth, birth weight, and stillbirth were included. The guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analyses were followed to conduct this study risk of bias and methods for data synthesis. RESULTS: A total of 34 studies were included. First, pregnant women exposed to low ambient temperature had an increased risk of preterm birth (risk ratio [RR] 1.08; 95% confidence interval [CI] 1.04-1.13). Subgroup analyses revealed that exposure during late pregnancy was more likely to induce preterm birth. In addition, only pregnant women exposed to <1st percentile of the mean temperature suffered increased risk of preterm birth. Moreover, pregnant women living in medium or hot areas were more prone to have preterm births than those in cold areas when exposed to low ambient temperatures. Asians and Blacks were more susceptible to low ambient temperatures than Caucasians. Second, pregnant women exposed to low ambient temperature had an increased risk of low birth weight (RR 1.07; 95% CI 1.03-1.12). Third, pregnant women had an increased risk of stillbirth while exposed to low ambient temperature during the entire pregnancy (RR 4.63; 95% CI 3.99-5.38). CONCLUSIONS: Exposure to low ambient temperature during pregnancy increases the risk of adverse birth outcomes. Pregnant women should avoid exposure to extremely low ambient temperature (<1st percentile of the mean temperature), especially in their late pregnancy. This study could provide clues for preventing adverse outcomes from meteorological factors. REGISTRATION No. CRD42021259776 at PROSPERO ( https://www.crd.york.ac.uk/PROSPERO/ ).

Objective:To analyze the clinical efficacy of treatment of cement dislodgement after vertebral augmentation for osteoporotic vertebral fractures.Methods:A retrospective study was conducted to analyze the data of 13 patients who had been treated at Department of Orthopaedics, The First Affiliated Hospital of Soochow University for cement dislodgement after vertebral augmentation for osteoporotic vertebral fractures from July 2013 to July 2022. There were 4 males and 9 females, with an average age of (76.5±8.6) years and a T value of bone mineral density of -3.3±0.6. By the CT and MRI features of cement dislodgement, their conditions fell in 4 types: cement loosening in situ (4 cases), anterior cement moving (6 cases), anterior cement moving with posterior bone mass moving (2 cases), and posterior cement moving (1 case). They were treated by percutaneous vertebroplasty (3 cases), pedicle screw fixation combined with bone graft fusion and decompression (7 cases), and conservative therapy (3 cases). The curative effects for surgical patients were evaluated by comparing their visual analogue scale (VAS), Oswestry dysfunction index (ODI) and cobb angle of kyphosis at preoperation, 1 week and 1 month postoperation, and the last follow-up, and Frankel grading for nerve injury as well. The curative effects for patients undergoing conservative treatment were evaluated by observing their symptoms.Results:This cohort was followed up for 7 (5, 12) months after treatment. The VAS scores [5.0 (4.0, 5.0) points, 3.0 (2.0, 3.0) points, and 3.0 (2.0, 3.0) points] in the 10 surgical patients at 1 week and 1 month postoperation and the last follow-up were significantly improved compared with the preoperative value [8.5 (8.0, 9.0) points] ( P<0.05); the VAS scores at 1 month postoperation and the last follow-up were also significantly improved compared with that at 1 week postoperation ( P < 0.05), but there was no significant difference between the last follow-up and 1 month postoperation ( P > 0.05). The ODIs (50.6%±4.2%, 37.8%±4.5%, and 29.3%±5.6%) in the 10 surgical patients at 1 week and 1 month postoperation and the last follow-up were significantly improved compared with the preoperative value (93.2%±3.6%), showing significant differences in pairwise comparisons ( P<0.05). The cobb angles [10.0 (9.0, 11.0)°, 9.0 (9.0, 11.0)°, and 10.0 (9.0, 12.0)°] in the 10 surgical patients at 1 week and 1 month postoperation and the last follow-up were significantly improved compared with the preoperative value [12.5 (11.0, 14.0)°] ( P<0.05) , but there was no statistically significant difference between the time points after operation ( P>0.05). The Frankel grading was significantly improved in the 6 patients with nerve injury after operation. Of the 3 patients undergoing conservative treatment, the symptoms were cured in one, showed no change during follow-up in one, and aggravated in one. Conclusion:Surgical treatment can significantly relieve pain, improve spinal dysfunction and repair nerve injury in patients with bone cement dislodgement after vertebral augmentation.

ObjectiveTo evaluate the efficacy and safety of a perioperative rehabilitation clinical pathway of acetabular fracture in light of orthopedics rehabilitation team approach. MethodsA prospective randomized control trial was conducted in 82 patients with acetabular fractures who had been admitted from the Emergency Department of Orthopaedic Trauma, Beijing Jishuitan Hospital from June, 2019 to January, 2021. The patients were randomly divided into control group (n = 41) and intervention group (n = 41). The control group was managed routinely, while the intervention group received the rehabilitation clinical pathway, for 24 weeks. The Visual Analogue Score (VAS) of pain, the Barthel Index (BI) and Majeed Pelvic Score were compared. ResultsFinally, 76 patients completed the trial. There was no statistical difference in VAS score between two groups in all periods (|Z| < 1.926, P > 0.05). The BI score was higher in the intervention group than in the control group at discharge, two weeks, six weeks and twelve weeks after operation (|Z| > 2.121, P < 0.05); and no significant difference was found before operation and 24 weeks after operation (|Z| < 1.862, P > 0.05). Majeed Pelvic Score was higher in the intervention group than in the control group two weeks, six weeks, twelve weeks and 24 weeks after operation (|Z| > 2.428, P < 0.05). Six, twelve and 24 weeks after operation, the excellent rate of Majeed Pelvic Score was higher in the intervention group than in the control group (χ² > 6.136, P < 0.05). ConclusionIn comparison with traditional protocol in acetabular fracture, the perioperative rehabilitation clinical pathway was proved effective and of great safety in the light of the integration of orthopedics and rehabilitation mode for improving the function and activities of daily living of patients.

Objective:To evaluate the efficacy and safety of perioperative rehabilitation approaches based on the concept of Enhanced Recovery After Surgery (ERAS) for pelvic fractures.Methods:A prospective randomized control trial was conducted to include 114 emergency patients who had been admitted to Department of Orthopaedic Trauma, Beijing Jishuitan Hospital for surgical treatment of pelvic fractures from June 2019 to December 2020. Of them, 57 were assigned into an intervention group according to a random digits table. They were 42 males and 15 females, aged from 18 to 77 years and subjected to management of pelvic fractures with tentative perioperative ERAS approaches which were adjusted at different stages. The other random 57 patients were assigned into a control group. They were 40 males and 17 females, aged from 17 to 70 years and subjected to management of pelvic fractures with conventional rehabilitation approaches which included postoperative in-hospital consultation and guidance by rehabilitation physicians. The 2 groups were compared in terms of Majeed pelvis scores and Barthel indexes at postoperative 2, 6, 12 and 24 weeks, and visual analogue scale (VAS) pain scores and SF36 scores at postoperative 12 and 24 weeks.Results:A total of 105 patients (55 in the intervention group and 50 in the control group) were completely followed up for 151 to 254 d (mean, 177 d). The 2 groups were comparable due to no significant difference between them in the preoperative general data ( P>0.05). The Majeed scores (44±13, 67±16, 86±14 and 98±7) and Barthel indexes (57±13, 79±16, 95±8 and 100±2) at postoperative 2, 6, 12 and 24 weeks in the intervention group were significantly higher than those in the control group [(35±16, 51±16, 73±14 and 91±12) and (45±19, 67±18, 86±12 and 98±4)] (all P<0.05). At postoperative 12 and 24 weeks, the SF-36 scores (129±15 and 141±6) in the intervention group were significantly higher than those in the control group (114±15 and 131±12) ( P<0.05). There was no significant difference in the pain degree between the 2 groups ( P>0.05). Conclusion:In management of pelvic fractures, compared with conventional perioperative rehabilitation approaches, the perioperative ERAS rehabilitation approaches may improve early functional outcomes and thus help the patients restore their activities of daily living earlier.

Objective:To investigate the expression of B lymphocyte induced maturation protein 1 (Blimp-1) in peripheral blood CD4 + T cells, CD19 + B cells and labial glands of patients with primary Sj?gren′s syndrome (pSS) and the correlation of Blimp-1 with clinical features. Methods:Expression of PRDM1 at mRNA level in CD4 + T cells, CD19 + B cells and labial gland tissues were detected by RT-PCR. Immunohistochemistry (IHC) was used to observe the distribution of Blimp-1. Correlation of PRDM1 expression at mRNA level with clinical indicators was analyzed. Results:PRDM1 expression at mRNA level in CD4 + T and CD19 + B cells were significantly higher in pSS group than in healthy control (HC) group ( P<0.01). Based on European League Against Rheumatism Sj?gren′s Syndrome Disease Activity Index (ESSDAI), the patients were classified into two groups: active group (ESSDAI≥5) and inactive group (ESSDAI<5). PRDM1 expression at mRNA level in CD4 + T and CD19 + B cells were also higher in the active group than in inactive group ( P<0.05). Blimp-1 protein accumulated around the acinus and duct of labial gland and in the germinal center in pSS patients. PRDM1 expression at mRNA level in labial gland tissues of pSS patients was positively correlated with lymphocyte infiltration ( r=0.781, P<0.001). Conclusions:pSS displayed high expression of Blimp-1. Blimp-1 might affect pSS disease activity and have clinical significance in pSS treatment.

Objective To investigate the change and significance of regulatory T cells (Tregs) in peripheral blood in patients with acute and chronic gout. Methods Flow cytometry was used to detect the ratio of Tregs in peripheral blood of healthy controls, patients with acute gout and patients with chronic gout. Enzyme linked immunosorbent assay (ELISA) was used to detect the levels of transforming growth factor (TGF)-βand interleukin (IL)-1βin plasma. Then, statistical analysis was conducted to analyze the changes and significance in different stages of gout, such as F test, Kruskal-Walls H test, q test and Pearson and Spearman correlation analysis. Results ① The percentage of CD4+CD25+Foxp+Treg/CD4+ T cells in peripheral blood was (1.22±0.27)％ in control group. While in patients with acute gout, it was (1.51±0.43)％, and (0.47±0.26)％in patients with chronic gout. There were statistical significant difference among the three groups ( F=101.39, P<0.05). The percentage of Tregs in acute gout group was significantly higher than that in control group and chronic gout group, while it was significantly lower in chronic gout group than in control group ( P<0.05). ②The concentration of TGF-β in plasma was (170 ±12) ng/L in control group, (214 ±77) ng/L in patients with acute gout and (179±21) ng/L in patients with chronic gout, the difference was statistically-significant (F=6.20, P<0.05). The concentration of TGF-β in plasma in acute gout group was significantly higher than the control group and chronic gout group, the difference was statistically significant (P<0.05), while the difference between chronic gout group and the control group was not statistically significant ( P>0.05). ③The con-centration of IL-1β in plasma in the control group was (4.8 ±1.3) ng/L, while that in patients with acute and chronic gout was (10.1±8.5) ng/L and (11.50±12.57) ng/L respectively, the difference between these three groupswas stati-sticallysignificant (P<0.05). The concentration of IL-1β in plasma in acute gout group and chronic gout group wassignificantly higher than that in the control group, the difference was statistical significant ( P<0.05). There was no significant difference between acute gout and chronic gout (P>0.05) patients. ④ The percentage of Tregs in peripheral blood of gout patients was negatively correlated with the duration of disease and the number of gout attacks within six months (duration of disease: r =-0.381, P <0.01 ; number of gout attacks: r=-0.518, P<0.01). But there wasno significant correlation to the concentration of TGF-β and IL-1β. Conclusion Tregsincreasesin acute gout and participate in the alleviation of gout inflammation, while the persistence of chronic gout may be related to the decrease of Tregs. Therefore, Tregs play an important regulatory role in the transformation of acute and chronic gout.
