ABSTRACT

Objective: This study aims to investigate the sleep quality of pregnant women in Xuhui District, Shanghai, and the related factors of sleep disturbances during pregnancy. Methods: From February 2019 to February 2021, we used online integrated sleep questionnaire (including PSQI, BQ, ESS, AIS) in Shanghai Jiao Tong University School of Medicine Affiliated Sixth People's Hospital, The International Peace Maternity and Child Health Hospitals of China Welfare Institution, and Shanghai Eighth People's Hospital, to investigate the sleep quality across pregnancy. We also collected maternal physical examination results, childbearing history, sociodemographic, and other clinical data. The prevalences and related factors of various sleep disturbances in pregnant women were analyzed, including insufficient/excessive nighttime sleep, low sleep efficiency, difficulty falling asleep, poor sleep quality, insomnia, daytime sleepiness, and high risk of sleep-disordered breathing (SDB). Results: This study includes 1 898 cases in the first trimester (T1), 3 099 cases in the second trimester (T2), and 1 539 cases in the third trimester (T3). Poor sleep quality (38.6%), daytime sleepiness (mild 41.9%, moderate 17.7%, severe 2.1%), and suspicious insomnia (32.3%) are most prevalent among women in T1 (P<0.01). In comparison, short sleep time (2.7%), long sleep time (8.6%), difficulty falling asleep (12.2%), poor sleep efficiency (35.4%), very poor sleep quality (6.7%), clinical insomnia (21.8%), and high-risk SDB (6.4%) are most prevalent among women in T3 (P<0.05). During pregnancy, late gestation (OR=1.016, 95%CI: 1.006-1.025) and multiple induced/drug abortions (OR=1.329, 95%CI: 1.043-1.692) are risk factors for poor sleep quality (PSQI>5), while multiple full-term deliveries (OR=0.800, 95%CI: 0.675-0.949) is its protective factor. Advanced maternal age (OR=0.976, 95%CI: 0.956-0.997), multiple full-term deliveries (OR=0.808, 95%CI: 0.680-0.959), late gestation (OR=0.983, 95%CI: 0.974-0.992) and hypertension (OR=0.572, 95%CI: 0.401-0.814) are protective factors for daytime sleepiness (ESS>6). The high-risk pregnancy category (OR=9.312, 95%CI: 1.156-74.978) is a risk factor for insomnia (AIS≥4), while multiple full-term deliveries (OR=0.815, 95%CI: 0.691-0.961) is its protective factor. High BMI (OR=1.334, 95%CI: 1.270-1.402) and hypertension (OR=4.427, 95%CI: 2.539-7.719) are risk factors for high-risk SDB in pregnant women. Conclusions: The prevalences of various sleep disturbances are high throughout pregnancy. Noticeably, symptoms of maternal SDB develop along with pregnancy. Different types of sleep disturbances are associated with different factors. Women of high-risk pregnancy category, in late gestation, with high BMI, hypertension, a history of induced/drug abortion, or without a history of full-term delivery can be at high risk of sleep disturbances during pregnancy.

ABSTRACT

Objective:To correlate neutrophil/lymphocyte ratio and platelet/lymphocyte ratio with diabetic nephropathy (DN).Methods:A total of 160 patients with type 2 diabetes mellitus (T2DM) who received treatment between January 2017 and October 2020 in People's Hospital of Suzhou National New & Hi-Tech Industrial Development Zone were included in this study. These patients were randomly divided into DN [urinary albumin-to-creatinine ratio (UACR) ≥ 30 μg/mg, n = 85) and non-DN (UACR < 30 μg/mg, n = 75)] groups according to UACR values. A total of 150 healthy controls who concurrently received health examination were included in the control group. The clinical data and biochemical indicators were collected in each group and their clinical characteristics were compared. The factors that affect DN were analyzed using a logistic regression model. Results:Neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) in patients with T2DM were (2.14 ± 1.12) and (175.00 ± 56.21), respectively, which were significantly higher than those in the healthy controls [(1.53 ± 0.29), (142.70 ± 37.25), t = 3.584, 5.642, both P < 0.05). NLR and PLR in the DN group were (2.64 ± 1.22) and (278.00 ± 72.23), respectively, which were significantly higher than those in the non-DN group [(1.80 ± 0.90), (193.00 ± 62.40), t = 2.738, 3.166, both P < 0.05)]. Logistic regression analysis showed that NLR and PLR are the risk factors of DN ( OR = 5.981, 1.807; 95% CI = 2.104-15.563, 1.327-2.795). Conclusion:Combined detection of NLR and PLR in the clinic may help early prediction of DN.

ABSTRACT

Objective@#: To retrospectively analyze the clinical characteristics and surgical experience of 10 adults with spinal extradural meningeal cysts (SEMCs) in the thoracolumbar spine which may further provide evidence for surgical decision-making. @*Methods@#: Ten adults with SEMCs in the thoracolumbar spine were surgically treated and enrolled in this study. Clinical manifestations, imaging data, intraoperative findings and postoperative outcome were recorded. @*Results@#: Clinical manifestations of SEMCs included motor and sensory dysfunction of the lower limbs and urination and defecation disturbance. The cysts presented as intraspinal occupying lesions dorsal to the spine, ranging from the T8 to L3 level. Defects of eight cases were found on preoperative magnetic resonance imaging (MRI). Selective hemilaminectomy or laminectomy were used to reveal the defect within the cyst, which was further sutured with microscopic technique. The final outcome was excellent or good in seven cases and fair in three cases. No recurrence was observed during follow-up. @*Conclusion@#: SEMCs are rare intraspinal cystic lesions. Radiography and MRI are clinically practical methods to assess defects within SEMCs. Selective hemilaminectomy or laminectomy may reduce surgical trauma. Detection and microscopic suturing of the defects are the key steps to adequately decompress the nervous tissue and prevent postoperative recurrence.

ABSTRACT

Objective: To investigate the prevalence and associated risk factors of metabolic syndrome (MS) in patients with obstructive sleep apnea (OSA). Methods: From July 2007 to June 2017, a total of 8 155 adult subjects, including 6 484 males and 1 671 females, aged 18-90 (43.13±12.28), body mass index 14.61~59.56 (25.59±3.98) kg/m2,who were admitted to the Department of Otorhinolaryngology head and Neck surgery of The Sixth People's Hospital affiliated to Shanghai Jiao Tong University, were retrospectively analyzed. All patients underwent polysomnography and biochemical tests. Subjects were divided into four groups (non-OSA, mild OSA, moderate OSA, and severe OSA) according to OSA severity. The prevalence of MS was expressed as percentage, and the correlation between OSA and MS and its characteristic pathophysiological indicators was evaluated by logistic regression model after adjusting for factors such as gender, age, BMI, neck circumference, hip circumference, smoking and alcohol consumption, and was expressed by odds ratio (OR). SPSS 25.0 software was used for statistical analysis. Results: The overall prevalence of MS was 43.6%, and that of non-/mild/moderate/severe OSA group was 18.6%, 30.4%, 43.8%, 57.1%.Logistic regression showed that patients with mild/moderate/severe OSA had an increased risk of MS compared with non-OSA patients, with adjusted OR values and confidence intervals of 1.27 (1.05-1.54), 1.84 (1.53-2.22), and 2.08 (1.76-2.46), respectively (P<0.01).In addition, indicators of OSA anoxic burden [oxygen drop index(Toxygen=7.1), minimum blood oxygen(Tminimum=56.3), blood oxygen saturation below 90% cumulative time ratio (TCT90=10.6) ]were closely associated with MS disease(P<0.01), but sleep fragmentation index (arousals index) was not significantly associated with MS disease. Conclusion: The risk of MS gradually increases with the severity of OSA, and the indicators reflecting OSA hypoxia burden are closely related to MS disease.

ABSTRACT

Objective: To compare the therapeutic efficacy of Han-uvulopalatopharyngoplasty (HUPPP) combined with radiofrequency ablation of tongue base or HUPPP with traction of tongue base on moderate to severe patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: This is a multicenter randomized controlled trial. From March 2017 to July 2019, moderate to severe OSAHS patients from three clinical center in Shanghai who were intolerant to continuous positive airway pressure (CPAP) and with velopharyngeal and glossopharyngeal plane obstruction were enrolled in this study. According to the surgical type, they were 1∶1 randomized to HUPPP plus radiofrequency ablation of tongue base group (Ablation group) or HUPPP plus traction of tongue base group (Traction group). All patients completed over-night standard Polysomnography (PSG), upper-airway assessment (Friedman classification, Müller test, CT and cephalometric examination), preoperative routine examination, Epworth Sleepiness Scale (ESS) and Quebec sleep questionnaire (QSQ). Six to 12 months after operation, all the above-mentioned examinations were repeatedly performed. Changes of aforementioned variables before and after operation were assessed. Results: A total of 43 patients with moderate to severe OSAHS were enrolled in this study. One patient lost to follow-up, the remaining 21 were allocated to Ablation group and 21 were allocated to Traction group. The total therapeutic efficacy of all patients was 69.05% (61.90% in Ablation group and 76.19% in Traction group), but there was no statistical significance between the two groups (P= 0.317). The value of sleep scale score (ESS and QSQ), objective sleep variables (apnea-hypopnea index, oxygen saturation, percentage of time with blood oxygen less than 90% in total sleep time, oxygen desaturation index and micro-arousals) and upper airway cross-sectional area (palatopharyngeal and retrolingual area) of the two groups were improved (P<0.05), but the differences between the two groups were not statistically significant (P>0.05). Conclusion: For moderate to severe OSAHS who had glossopharyngeal plane obstruction, both HUPPP plus radiofrequency ablation of tongue base or HUPPP plus traction of tongue base are effective treatment for OSAHS, and the curative effect is similar. The choice of surgical type could be selected according to patient's or surgical conditions.

ABSTRACT

OBJECTIVE@#To observe the effect of electroacupuncture (EA) on the rehabilitation of knee joint function after anterior cruciate ligament (ACL) reconstruction.@*METHODS@#A total of 140 patients with ACL reconstruction were randomly divided into an observation group (58 cases recruited, 12 cases dropped out) and a control group (65 cases recruited, 5 cases dropped out). The patients in the control group were treated with routine rehabilitation treatment. The patients in the observation group, on the basis of the treatment in the control group, were treated with EA at Fengshi (GB 31), Futu (ST 32), Zusanli (ST 36), Shangjuxu (ST 37), Fenglong (ST 40), Xuanzhong (GB 39), Diji (SP 8) and Sanyinjiao (SP 6) on the affected side (2 Hz/100 Hz of dilatational wave, 2-5 mA). Each EA treatment lasted 20-30 min, twice a day for 7 days. The swelling degree (d), pain visual analogue scale (VAS), knee joint range of motion (ROM), scores of International Knee Documentation Committee (IKDC) subjective short form and scores of Lysholm were observed in the two groups 1 day, 1 month, 3 months, 6 months and 1 year after operation.@*RESULTS@#One month and 3 months after operation, the swelling degree (d) and VAS scores in the observation group were lower than those in the control group (0.05). One month, 3 months, 6 months and 1 year after operation, the ROM of the knee joint in the observation group was higher than that in the control group (<0.05), the IKDC score and Lysholm score were higher than those in the control group (<0.05). Within one year, there were no relaxations, fractures and other related complications in the two groups. The pivot shift test, anterior drawer test and the Lachman test were all negative.@*CONCLUSION@#EA combined with routine rehabilitation training could obviously reduce the pain of knee joint, improve the swelling degree, increase the ROM of knee joint, promote the functional recovery in patients with ACL reconstruction, which are superior to rehabilitation training alone.

ABSTRACT

Artificial intelligence (AI) is rapidly being applied to a wide range of fields, including medicine, and has been considered as an approach that may augment or substitute human professionals in primary healthcare. However, AI also raises several challenges and ethical concerns. In this article, the author investigates and discusses three aspects of AI in medicine and healthcare: the application and promises of AI, special ethical concerns pertaining to AI in some frontier fields, and suggestive ethical governance systems. Despite great potentials of frontier AI research and development in the field of medical care, the ethical challenges induced by its applications has put forward new requirements for governance. To ensure "trustworthy" AI applications in healthcare and medicine, the creation of an ethical global governance framework and system as well as special guidelines for frontier AI applications in medicine are suggested. The most important aspects include the roles of governments in ethical auditing and the responsibilities of stakeholders in the ethical governance system.

ABSTRACT

Objective@#To examine the effect of posterior reduction in atlantoaxial dislocation (AAD) associated with basilar invagination(BI) using Xuanwu occipital-cervical fusion system in single stage.@*Methods@#Thirty-seven AAD accompanied with BI cases treated at Department of Neurosurgery, Xuanwu Hospital, Capital Medical Universiy and the Second Hospital of Hebei Medical University were retrospective analyzed. There were 15 males and 22 females with age of (42.3±12.3) years (range: 18-69 years). All the cases had congenital osseous abnormalities, such as assimilation of atlas and abnormal cervical fusion. Anterior tissue was released through posterior route followed by cage implantation into facet joint and occipital-cervical fixation with cantilever technique. The clinical results were evaluated using Japanese Orthopedic Association scale(JOA) and the main radiological measurements including anterior atlantodental interval (ADI), the distance of odontoid tip above Chamberlain line, clivus-canal angle(CCA) and the length of syrinx were collected. The preoperative and postoperative JOA score and radiological measurements were compared by paired t-test.@*Results@#The mean JOA score of the patients increased from 10.5 to 14.4 at the one-year follow-up(t=14.3, P=0.00). Complete reduction of AAD and BI was achieved in 34 patients.The mean clivus-canal angle improved from (118.0±6.5) degrees preoperative to (143.7±5.0) degrees postoperative(t=6.2, P=0.00). Shrinkage of the syrinx was observed 1 week after surgery in 24 patients, and 6 months in 31 patients.Twenty-eight patients achieved bone fusion 6 months after surgery. All the patients achieved bone fusion 12 months after surgery. One-side vertebral artery occlusion was diagnosed in 1 case postoperatively for transient dizziness, and relieved in 2 weeks.Two patients developed moderate neck pain after surgery, and relieved in 1 month. No implant failure, spacer subsidence or infection was observed.@*Conclusions@#The treatment of AAD associated with BI using Xuanwu occipital-cervical fusion system from posterior approach in single stage is effective and safe. Cage implantation intraarticularly and fixation with cantilever technique achieve complete reduction in most cases.

ABSTRACT

Objective To improve the recognition and knowledge of autosomal dominant polycystic kidney disease (ADPKD) related male infertility through investigation for MRI characteristics of this disease. Methods Fourteen patients confirmed with ADPKD related obstructive azoospermia were retrospectively analyzed. All patients referred to clinic with male infertility, and obstructive azoospermia were additionally confirmed by laboratory tests and clinical examination. Subsequent abdominopelvic MR examinations were performed to comfirm obstructive factors and obstructive location. All patients were performed an abdominopelvic MR examination including non-enhanced and enhanced MR. MR imaging characteristics were analyzed and summarized by two experienced radiologists. Results MRI results for all cases were classified into 4 groups:10 cases with bilateral polycystic kidneys and bilateral seminal vesicle cysts, 2 cases with bilateral polycystic kidneys, polycystic liver and bilateral seminal vesicle cysts, 1 case with bilateral polycystic kidneys, polycystic liver and absence of bilateral seminal vesicles, 1 case with bilateral cystic kidneys, bilateral seminal vesicle cysts as well as Müllerian duct cyst. A wide range of coronal T2WI scan was necessary to observe cystic lesions in both liver and bilateral kidneys as well as abnormal changes in pelvis. The obstructive sites in all cases were located in level from ejaculatory duct to seminal vesicle. Bilateral seminal vesicle cysts presented as significantly dilated glandular ducts of seminal vesicles, in which flocculence or nodular sediment can be found. Conclusion Male infertility caused by ADPKD-related deferential duct obstrution is characterized by bilateral polycystic kidney disease and Seminal vesicle ejaculatory duct obstruction in MRI, which can be combined with other abnormalities.

ABSTRACT

Fenofibrate, an agonist for peroxisome proliferator-activated receptor alpha (PPAR-α), lowers blood pressure, but whether this action is mediated via baroreflex afferents has not been elucidated. In this study, the distribution of PPAR-α and PPAR-γ was assessed in the nodose ganglion (NG) and the nucleus of the solitary tract (NTS). Hypertension induced by drinking high fructose (HFD) was reduced, along with complete restoration of impaired baroreceptor sensitivity, by chronic treatment with fenofibrate. The molecular data also showed that both PPAR-α and PPAR-γ were dramatically up-regulated in the NG and NTS of the HFD group. Expression of the downstream signaling molecule of PPAR-α, the mitochondrial uncoupling protein 2 (UCP2), was up-regulated in the baroreflex afferent pathway under similar experimental conditions, along with amelioration of reduced superoxide dismutase activity and increased superoxide in HFD rats. These results suggest that chronic treatment with fenofibrate plays a crucial role in the neural control of blood pressure by improving baroreflex afferent function due at least partially to PPAR-mediated up-regulation of UCP2 expression and reduction of oxidative stress.

ABSTRACT

Objective To investigate the role of vitamin D in the synthesis and degradation of aggrecan in rat articular chondrocytes at cellular level. Methods Rat articular chondrocytes were stimulated by IL-1α, IL-1β and TNF-α, respectively. Normal and inflammatory chondrocytes were treated with different doses of vitamin D, respectively. CCK8, Flow cytometry, real time-PCR and western blot analysis were used to examine the proliferation activity and apoptosis level of chondrocytes, and the expression of aggrecan, ADAMTS-4 and ADAMTS-5 at both mRNA and protein levels. Results IL-1α,IL-1β and TNF-α significantly decreased the proliferation activity and increased the apoptosis level of the chondrocytes. Furthermore, IL-1α, IL-1β and TNF-α significantly decreased the expression of aggrecan, and increased the expressions of ADAMTS-4 and ADAMTS-5 at both mRNA and protein levels in the chondrocytes. 1α,25 (OH)2D3supplementation significantly increased the proliferation activity and decreased the apoptosis level of chondrocytes stimulated by IL-1α, IL-1β and TNF-α in a dose-dependent manner, but not affected the normal chondrocytes. Meanwhile, 1α,25(OH)2D3also significantly increased the expression of aggrecan, and decreased the expressions of ADAMTS-4 and ADAMTS-5 at both mRNA and protein levels in the chondrocytes under inflammatory conditions. Conclusions Vitamin D may promote the anabolism of aggrecan and inhibit aggrecanase activity in chondrocytes under inflammatory conditions, which may impact overall protection for articular cartilage.

ABSTRACT

Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound,the examiner and interpreter of the image are critical care medicine physicians.The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes.With the idea of critical care medicine as the soul,it can integrate the above information and clinical information,bedside real-time diagnosis and titration treatment,and evaluate the therapeutic effect so as to improve the outcome.CUS is a traditional technique which is applied as a new application method.The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept,implementation and application of CUS.It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure.At the same time,the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications,and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS.Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group,based on the rich experience of clinical practice in critical care and research,combined with the essence of CUS,to learn the traditional ultrasonic essence,established the clinical application technical specifications of CUS,including in five parts:basic view and relevant indicators to obtain in CUS;basic norms for viscera organ assessment and special assessment;standardized processes and systematic inspection programs;examples of CUS applications;CUS training and the application of qualification certification.The establishment of applied technology standard is helpful for standardized training and clinical correct implementation.It is helpful for clinical evaluation and correct guidance treatment,and is also helpful for quality control and continuous improvement of CUS application.

ABSTRACT

OBJECTIVE: To evaluate the incidence, characteristics, and variations of the falcine sinus with contrast-enhanced three-dimentional (3D) thin-section magnetic resonance (MR) images. MATERIALS AND METHODS: retrospective review identified 1531 patients (745 males and 786 females, 2 months to 85 years) who underwent cranial MR imaging including T1-weighted imaging, T2-weighted imaging, T2-weighted fluid-attenuated inversion recovery, contrast-enhanced 3D thin-section sagittal scans, and MR venography, from June 2014 to January 2016. The incidence, characteristics of the falcine sinus, and coexisted intracranial lesions were confirmed by two neuroradiologists. RESULTS: Falcine sinuses were identified in 81 (38 males and 43 females) cases (5.3%, 81/1531, 5 months to 76 years of age) with calibers ranging from 2.3 mm to 17.0 mm. Three major forms of falcine sinuses were defined: arch-like (n = 47), stick-like (n = 22), and bifurcated (n = 12). Persistent falcine sinuses were found in 57 cases, among which 3 cases showed complicated cerebral anomalies, and 2 cases showed smaller straight sinuses. Recanalization of falcine sinuses were found in 24 cases, including 17 cases with tumor compression, 6 cases with cerebral venous sinus thrombosis, and one case with hypertrophic meningitis. CONCLUSION: Falcine sinus is not as rare as has been reported previously. Most falcine sinuses are not associated with congenital cerebral abnormalities. Diseases that cause increased pressure in the venous sinus may lead to recanalization of falcine sinus. Illustrating the characteristics of falcine sinus may prompt a more comprehensive understanding and diagnosis of associated diseases, and avoid potential surgical damage in the future.

ABSTRACT

Objective To identify a strain screen which utilize dibutyl phthalate (DBP) as the sole carbon source and to explore the optimal conditions for the degradation of DBP. Methods The solid leachate was inoculated in minimal salt medium (MSM) supplemented with DBP as the sole carbon and energy source to isolate the targeted strain. The strain was identified through colony phenotype, transmission electron microscope and 16SrDNA gene sequence analysis. The targeted strain was inoculated to the above medium with different pH and temperature. The optimal temperature and pH of the microbial degradation of DBP were studied with determination of the DBP residue and bacterial biomass. Results One bacterial strain named L6 was isolated from the solid with adding DBP as the sole carbon source. Based on its morphology, physiochemical characteristics, and 16SrDNA sequence, the strain was identified as Methylobacterium sp. The optimal pH and temperature for its biodegradation activities were 7 and 30℃, respectively. The targeted strain could degrade 85% of 800 mg/L DBP within 120 hours. Conclusion Based on the high removal rate, the isolated Methylobacterium sp. L6 has a potential for bioremediation technology of DBP pollution.

ABSTRACT

Objective To observe imaging features of uterus duplication combined with mesonephric duct dysplasia related abnormalities.Methods Imaging data of 17 female with uterus duplication and renal dysplasia were retrospectively analyzed.Seven patients underwent CT and 10 patients underwent MR scanning.Results The basic abnormalities in 17 patients were uterus duplication combined with unilateral renal-ureter dysplasia with/without other associated malformation which were further classified as follows:①7 patients presented as basic abnormalities without other associated malformations,include 5 (CT diagnosed 1,MR diagnosed 4) with uterus duplex and unilateral renal-ureter agenesis,2 (CT 1,MR 1) with uterus bifidus and unilateral renal-ureter dysplasia;②2 patients (CT 1,MR 1) presented as basic abnormalities accompanied with ectopic ureter orifice,uterus duplex and unilateral renal dysplasia with ectopic ureter orifice opening in vagina;③5 patients (CT 3,MR 2) of Herlyn-Werner-Wunderlich syndrome presented as uterus duplication,oblique vagina septum as well as unilateral renal-ureter dysplasia,which shown as uterus duplex,oblique vaginal septum with hematocolpos,also unilateral renal-ureter agenesis;④2 patients presented as basic abnormalities accompanied with mesonephric residual cyst,CT showed one with uterus duplex and unilateral renal-ureter agenesis with ipsilateral mesonephric residual cyst,MRI showed as the other one with Herlyn-Werner-Wunderlich syndrome combined with mesonephric residual cyst opening in vagina;⑤MRI showed 1 patient with basic abnormalities and a nephrogenic adenoma,which demonstrated as uterus duplex combined with left renal-ureter agenesis,and a tumor on the left wall of bladder accompanied with endometriosis.Conclusion Further classification into 5 types from simple to complex based on uterus duplication combined with unilateral renal-ureter dysplasia with/without other associated malformations is helpful to the diagnosis and treatment of these abnormalities.
