ABSTRACT
AIM: To investigate the short-term visual quality outcomes after femtosecond laser small incision lenticule extraction(SMILE)and evolution implantable collamer lens(EVO-ICL)implantation for the correction of moderate myopia.METHODS: Prospective control study. A total of 51 cases(51 eyes)with moderate myopia who underwent SMILE or EVO-ICL implantation surgery at Weifang Eye Hospital from April 2021 to February 2022 were selected. They were divided into SMILE group(30 patients, 30 eyes)and EVO-ICL group(21 patients, 21 eyes)according to the surgical methods. The changes of visual acuity [uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA)], diopter [spherical equivalent(SE)] and related parameters of optical quality analysis system(OQAS Ⅱ)were observed before surgery and at 1wk, 1 and 3mo after surgery, and the quality of vision(QoV)questionnaire was completed.RESULTS: At 3mo after surgery, the safety index(postoperative CDVA/preoperative CDVA)of SMILE gruop and EVO-ICL group were 1.20(1.00, 1.20)and 1.20(1.00, 1.38), respectively, the efficacy index(postoperative UDVA/preoperative CDVA)were 1.00(1.00, 1.20)and 1.00(1.00, 1.20), respectively, and the percentage of SE within ±0.50D was 87% and 100%, respectively. In SMILE group, the objective scattering index(OSI)was increased after surgery, while modulation transfer function cutoff frequency(MTF cutoff), contrast visual acuity(VA)100%, and VA20% at 1wk and 1mo after surgery, and Strehl ratio(SR)and VA9% at each time point after surgery were all decreased compared with those before surgery(all P<0.05). The OSI, MTF cutoff, SR and VA of EVO-ICL group showed no difference at each time point after surgery compared with those before surgery(all P>0.05). The most common visual symptoms after SMILE and EVO-ICL implantation were visual haze and halos, respectively.CONCLUSION: Both SMILE and EVO-ICL implantation have good safety, efficacy and predictability in the short term after the correction of moderate myopia. Both groups had visual symptoms after surgery, but the overall satisfaction of patients was high. Furthermore, EVO-ICL implantation has better objective visual quality performance.
ABSTRACT
AIM: To measure the indexes including postoperative distance, middle, near visual acuity and near stereopsis vision of patients with high myopia cataract and corneal astigmatism by femtosecond laser, which can quantify the diameter of capsulorhexis opening, and to evaluate the availability and necessity of Toric intraocular lenses(IOL)in high myopia.METHODS: Prospective case-control study. Patients with binocular high myopia cataract and corneal astigmatism who undergone femtosecond laser-assisted cataract surgery in our hospital were selected, and they were divided into two groups, with 20 cases(40 eyes)in group A(Toric IOL)and 20 cases(40 eyes)in group B(IQ IOL). Indexes, including preoperative corneal astigmatism and spherical equivalent and best-corrected distance visual acuity, uncorrected middle visual acuity, uncorrected near visual acuity, residual refractive astigmatism, near stereopsis acuity, total high-order aberration and total spherical aberration, were measured postoperatively at 7d, 1 and 3mo.RESULTS: The uncorrected middle and near visual acuity, Titmus near stereopsis acuity and residual astigmatism at 7d, 1 and 3mo after surgery were significantly improved in the Toric IOL group than the non-Toric group(all P<0.05). The dependence on glasses was reduced. The postoperative best-corrected distance visual acuity, total high-order aberration and total spherical aberration of the two groups showed no statistically significant differences(all P>0.05).CONCLUSIONS: The implantation of Toric IOL in patients with high myopia cataract and corneal astigmatism can effectively correct corneal astigmatism, improve postoperative uncorrected middle and near visual acuity and near stereopsis visual function, reduce postoperative dependence on glasses and enhance binocular stereopsis visual function.
ABSTRACT
Objective To analyze the epidemiological characteristics of pulmonary tuberculosis in the elderly people in Wuhan during 2016-2020, and to provide a basis for formulating effective prevention and control strategies and measures. Methods Using the National Tuberculosis Information Management System, a descriptive statistical analysis was performed on the medical records of elderly (≥60 years old) pulmonary tuberculosis patients registered in Wuhan from 2016 to 2020. Results A total of 9 427 elderly pulmonary tuberculosis patients were registered in Wuhan during 2016-2020, accounting for 32.07% of the total number of registrations in the whole population. The reported incidence rate of tuberculosis in the elderly was significantly higher than that in the total population, and the reported incidence rates in both the elderly and the general population showed declining trends (whole population χ2trend=216.97, P2trend=153.57, P<0.05). The time distribution showed that more cases occurred from April to November (70.90%). The top three districts with the largest number of registered cases were far urban areas, namely Huangpi District (13.81%), Xinzhou District (11.55%), and Jiangxia District (9.82%). The ratio of male to female with pulmonary tuberculosis in elderly patients was 2.85:1. Among the elderly pulmonary tuberculosis, the most registered cases were in the age group of 60 ~ years old, followed by 65 ~ years old. The proportion of smear-positive in elderly patients with pulmonary tuberculosis retreatment was 16.83%. Conclusion From 2016 to 2020, the epidemic situation of elderly pulmonary tuberculosis showed a downward trend in Wuhan. However, the elderly population with tuberculosis registrations still accounted for a relatively high proportion of the total population. According to the epidemiological characteristics of pulmonary tuberculosis among the elderly, the city should carry out tuberculosis prevention and control work in a timely, appropriate and focused manner.
ABSTRACT
Objective:To observe the expression of microRNA (miRNA)-7159-5p in gastric cancer tissues, and explore its effect on the proliferation and invasion of gastric cancer cells and its molecular mechanism.Methods:The cancer tissues and adjacent tissues of 29 patients with gastric cancer who underwent surgical resection in Hubei 672 Orthopedic Hospital of Integrated Traditional Chinese and Western Medicine from March 2018 to November 2019 were collected. Fluorescence real-time quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression of miR-7159-5p in gastric cancer tissues and adjacent tissues, gastric cancer cell lines and normal gastric epithelial cell lines. Select the cell line with the lowest expression of miR-7159-5p, set the control group and the experimental group, and be transfected with control and miR-7159-5p mimics respectively. qRT-PCR was used to detect the expression of miR-7159-5p in transfected cells. The lymphocyte proliferation test (MTS method) was used to detect the proliferation of transfected cells, and the Transwell chamber method was used to detect the invasion activity of transfected cells. The miRNAMap database and dual luciferase reporter gene experiment were used to predict and verify the target genes of miR-7159-5p. qRT-PCR and Western blot were used to detect the expression of target genes in transfected cells.Results:The expression of miR-7159-5p in gastric cancer tissues was lower than that in adjacent tissues ( P<0.01), the expression of miR-7159-5p in gastric cancer cell lines was lower than that of normal gastric epithelial cells (all P<0.01), and the expression of miR-7159-5p was the lowest in SGC7901 cells ( P<0.01). After transfection, the expression of miR-7159-5p in SGC7901 cells of the experimental group was significantly higher than that in the control group ( P<0.01). After transfection, the proliferation activity and the cell invasion activity of the experimental group was significantly lower than that of the control group (all P<0.01). The target gene of miR-7159-5p was tripartite motif 26 (TRIM26). After transfection, the expression of TRIM26 mRNA in SGC7901 cells of the experimental group was significantly lower than that in the control group ( P<0.01). Western blot showed that after transfection, the expression of TRIM26, c-Myc, cyclin D1, β-catenin protein were lower than those in the control group (all P<0.05). Conclusions:The expression of miR-7159-5p is low in gastric cancer tissues, and miR-7159-5p can inhibit the proliferation and invasion of SGC7901 cells by down-regulating the expression of TRIM26.
ABSTRACT
Anxiety disorders are the most prevalent mental health condition.More and more studies have found that interoceptive sensitivity, such as the sensitivity of the body to a series of physiological activities such as heart rate, respiration, blood pressure and so on, is closely related to the susceptibility to anxiety disorders.So, understanding the role of interoception in the occurrence of anxiety disorders plays an important role in understanding the pathogenesis of the disease and guiding treatment.This article reviewed the pathogenesis of anxiety disorders, the interaction between increased interoceptive sensitivity and abnormal activation of the amygdala, which results in pathological anxiety, the insula also regulates emotional responses by regulating interoception.It is also associated with genes and neurotransmitters, which may be important biomarkers of anxiety disorders.At the same time, interoception is also associated with genes and neurotransmitters, which may also be important biomarkers of anxiety disorders.In terms of treatment, we can use respiratory therapy to regulate respiratory perception, apply rTMS to stimulate the relevant network of interoception, and use electroencephalography to reflect interoception biofeedback and other treatment methods to improve interoception, to alleviate anxiety symptoms.In conclusion, the abnormal sensitivity of interoception plays an important role in the occurrence of anxiety disorders.Currently, there are many therapeutic methods for the treatment of anxiety disorders based on interoception, but the relevant therapeutic mechanism is unclear.Therefore, future research needs to explore the mechanism of interoception in anxiety and explore the mechanism of related treatment.

After treatment, the total score of the quality of life questionnaire was significantly higher in the observation group than in the control group [(61.58 ± 8.57) points vs. (40.98 ± 8.35) points, t = 12.17, P < 0.001]. There was no significant difference in total incidence of adverse reactions between observation and control groups [10.00% (5/50) vs. 14.00% (7/50), χ2 = 0.38, P > 0.05]. Conclusion:Desloratadine combined with Tongqiao Biyan capsule can better improve the symptoms of allergic rhinitis and better reduce inflammation without increasing adverse drug reactions compared with desloratadine alone.
ABSTRACT
Interference with quorum sensing(QS)represents an antivirulence strategy with a significant promise for the treatment of bacterial infections and a new approach to restoring antibiotic tolerance.Over the past two decades,a novel series of studies have reported that quorum quenching approaches and the discovery of quorum sensing inhibitors(QSIs)have a strong impact on the discovery of anti-infective drugs against various types of bacteria.The discovery of QSI was demonstrated to be an appropriate strategy to expand the anti-infective therapeutic approaches to complement classical antibiotics and antimicrobial agents.For the discovery of QSIs,diverse approaches exist and develop in-step with the scale of screening as well as specific QS systems.This review highlights the latest findings in strategies and methodologies for QSI screening,involving activity-based screening with bioassays,chemical methods to seek bacterial QS pathways for QSI discovery,virtual screening for QSI screening,and other potential tools for interpreting QS signaling,which are innovative routes for future efforts to discover additional QSIs to combat bacterial infections.
ABSTRACT
Objective:To investigate the application value of three dimensional (3D) imaging fusion navigation system (hereinafter referred as navigation system) in laparoscopic pan-creatic surgery.Methods:The retrospective and descriptive study was conducted. The clinical data of two volunteers, including volunteer 1 undergoing laparoscopic pancreaticoduodenectomy for cholangiocarcinoma and volunteer 2 undergoing laparoscopic pancreaticotomy + splenectomy for pancreatic cancer, who were admitted to the Second Hospital of Hebei Medical University from December 2020 to May 2021 were collected. The 2 volunteers were females, aged 68 years and 40 years, respectively. The self-developed navigation system was applied in laparoscopic simulator model test, including in rigid-body model and prosthesis model, and clinical test. Observation indicators: (1) results of model test; (2) results of clinical test. Measurement data with normal distribution were represented as Mean± SD. Results:(1) Results of model test. The rigid-body model or prosthesis model with occlusion can be seen in the laparoscopic visual field of the initial laparoscopic simulator. The rigid-body model or prosthesis model with occlusion and rigid-body model or prosthesis model without occlusion can be seen in the 3D visual reconstruction image of enhanced computer tomography (CT) examination. The rigid-body model or prosthesis model with occlusion can be seen in the laparoscopic visual field of the initial laparoscopic simulator after the 3D visual reconstruction image was superimposed and fused with the real-time laparoscopic image. Both of the rigid-body model and prosthesis model were in high consistency, with the distance error of marker points were (0.26±0.11)mm and (0.29±0.18)mm, respectively. (2) Results of clinical test. The abdominal organs and blood vessels with occlusion of the 2 volunteers can be seen in the initial laparoscopic visual field. The location of tumor, important organs and blood vessels can be seen in the navigation system using the 3D visual reconstruction image of enhanced CT examination. The location of tumor, important organs and important blood vessels can be seen in the laparoscopic visual field after the 3D visual reconstruction image was superimposed and fused with the real-time laparoscopic image. The distance error of marker points of the volunteer 1 was (1.36±0.57)mm and the distance error of marker points of the volunteer 2 was (1.24±0.33)mm.Conclusions:The self-developed navigation system can integrate the preoperative 3D visual reconstruction image of enhanced CT examination and the intraoperative real-time laparoscopic image with a good effect. The relationship between deep tissue and blood vessels which is not clarified in conventional laparoscopy can be shown in the navigation system assisted laparoscopic pancreatic surgery.

Objective@#The hippocampus is thought to be a vulnerable target of microwave exposure. The aim of the present study was to investigate whether 20-hydroxyecdysone (20E) acted as a fate regulator of adult rat hippocampal neural stem cells (NSCs). Furthermore, we investigated if 20E attenuated high power microwave (HMP) radiation-induced learning and memory deficits.@*Methods@#Sixty male Sprague-Dawley rats were randomly divided into three groups: normal controls, radiation treated, and radiation+20E treated. Rats in the radiation and radiation+20E treatment groups were exposed to HPM radiation from a microwave emission system. The learning and memory abilities of the rats were assessed using the Morris water maze test. Primary adult rat hippocampal NSCs were isolated in vitro and cultured to evaluate their proliferation and differentiation. In addition, hematoxylin & eosin staining, western blotting, and immunofluorescence were used to detect changes in the rat brain and the proliferation and differentiation of the adult rat hippocampal NSCs after HPM radiation exposure.@*Results@#The results showed that 20E induced neuronal differentiation of adult hippocampal NSCs from HPM radiation-exposed rats via the Wnt3a/β-catenin signaling pathway in vitro. Furthermore, 20E facilitated neurogenesis in the subgranular zone of the rat brain following HPM radiation exposure. Administration of 20E attenuated learning and memory deficits in HPM radiation-exposed rats and frizzled-related protein (FRZB) reduced the 20E-induced nuclear translocation of β-catenin, while FRZB treatment also reversed 20E-induced neuronal differentiation of NSCs in vitro.@*Conclusion@#These results suggested that 20E was a fate regulator of adult rat hippocampal NSCs, where it played a role in attenuating HPM radiation-induced learning and memory deficits.

Cerebellar Purkinje cells (PCs) exhibit two types of discharge activities: simple spike (SS) and complex spike (CS). Previous studies found that noradrenaline (NA) can inhibit CS and bidirectionally regulate SS, but the enhancement of NA on SS is overwhelmed by the strong inhibition of excitatory molecular layer interneurons. However, the mechanism underlying the effect of NA on SS discharge frequency is not clear. Therefore, in the present study, we examined the mechanism underlying the increasing effect of NA on SS firing of PC in mouse cerebellar cortex in vivo and in cerebellar slice by cell-attached and whole-cell recording technique and pharmacological methods. GABAA receptor was blocked by 100 µmol/L picrotoxin in the whole process. In vivo results showed that NA significantly reduced the number of spikelets of spontaneous CS and enhanced the discharge frequency of SS, but did not affect the discharge frequency of CS. In vitro experiments showed that NA reduced the number of CS spikelets and after hyperpolarization potential (AHP) induced by electrical stimulation, and increased the discharge frequency of SS. NA also reduced the amplitude of excitatory postsynaptic current (EPSC) of parallel fiber (PF)-PC and significantly increased the paired-pulse ratio (PPR). Application of yohimbine, an antagonist of α2-adrenergic receptor (AR), completely eliminated the enhancing effect of NA on SS. The α2-AR agonist, UK14304, also increased the frequency of SS. The β-AR blocker, propranolol, did not affect the effects of NA on PC. These results suggest that in the absence of GABAA receptors, NA could attenuate the synaptic transmission of climbing fiber (CF)-PC via activating α2-AR, inhibit CS activity and reduce AHP, thus enhancing the SS discharge frequency of PC. This result suggests that NA neurons of locus coeruleus can finely regulate PC signal output by regulating CF-PC synaptic transmission.

ABSTRACT
Objective:To study the clinical characteristics of orobuccal involuntary movements (OB) induced by anticholinergic agents.Methods:The clinical characteristics of patients with OB induced by anticholinergic agents in Qilu Hospital (Qingdao) from April 2018 to October 2021 and cases reported in the literature were analyzed in combination with literature review.Results:Seven patients in Qilu Hospital (Qingdao) and 10 cases in the literature were analyzed. Of these 7 patients, 6 were elderly female, with involuntary, repetitive, stereotypical movements of the lips, tongue, and sometimes of the jaw after intake of anticholinergic medication with the latency 21-60 days and the involuntary movements improved 7-30 days after discontinuation of anticholinergic medication. Of 10 cases reported in the literature, 7 were elderly female and 8 only with OB and 2 patients had extremities dyskinesia plus OB. Involuntary movements appeared after latency of 3-93 days following the introduction of anticholinergic drugs and resolved after latency of 2-60 days following their withdrawal.Conclusions:OB induced by anticholinergic agents mostly occur sub-acutely during the treatment of Parkinson′s disease, and can resolve in a short time after withdrawal, which is independent of the dose of levodopa and anticholinergic agents. The aging, female, and anxiety and depression may be the risk factors.
ABSTRACT
Objective:To investigate the associations between small diffusion-weighted imaging (DWI) hyperintensities lesions and total cerebral small vessel disease (cSVD) burden and the influence on prognosis in patients with acute intracerebral hemorrhage (ICH).Methods:Consecutive patients with acute spontaneous ICH from January 2018 to June 2021 were recruited in the Stroke Center of Zhengzhou People′s Hospital. Magnetic resonance imaging was performed to quantify DWI hyperintensities lesions and cSVD imaging markers, including white matter hyperintensities, enlarged perivascular spaces, lacunes and cerebral microbleeds, which were calculated for the total cSVD burden (0-4 points). The prognosis was assessed with the modified Rankin Scale (mRS) at discharge and 90-day. Multivariable Logistic regression models were adopted to explore the associations between DWI lesions and total cSVD burden and clinical outcome.Results:Of 283 included patients, 59 (20.8%) had small DWI lesions, 32 (11.3%) had multiple lesions. They were mostly punctate, mainly located in the cortical and subcortical regions, and scattered in multiple vascular territories. With the increase of cSVD burden, the number of DWI lesions gradually increased. Spearman correlation analysis showed that the total cSVD burden was positively correlated with the number of DWI lesions ( r=0.21, P<0.001). In multivariable regression analyses, the total cSVD burden was independently associated with DWI lesions ( OR=1.63, 95% CI 1.23-2.15, P=0.001). The 90-day poor outcome (mRS scores≥4) in patients with DWI lesions was significantly higher than those without DWI lesions (39.3% vs 16.3%, χ 2=14.38, P<0.001), while there was no statistically significant difference in the poor outcome of discharge between the two groups (26.5% vs 17.7%, χ 2=3.06, P=0.080). With the increase in the number of DWI lesions, the 90-day poor outcome increased significantly (trend chi-squared test χ 2=11.50, P=0.001). Multivariable analyses showed that DWI lesions ( OR=4.39, 95% CI 1.92-10.03, P<0.001) and their number ( OR=1.42, 95% CI 1.06-1.90, P=0.018) were independently associated with the 90-day poor outcome. Conclusions:Higher total cSVD burden is an independent risk factor for small DWI lesions in patients with ICH. Small DWI lesions were independently associated with the 90-day poor outcome, but not with the discharge outcome.
ABSTRACT
Objective:To investigate the expression of RASAL3 in intrahepatic cholangiocarcinoma (iCCA) and the mechanism of promoting iCCA development.Methods:Tumor and paracancerous tissues were collected from 185 iCCA patients, the expression of RASAL3 was detected by immunohistochemistry, RT-qPCR and Western blot. The expression of RASAL3 and FXYD6 mRNA and protein in human cholangiocarcinoma cell line and human bile duct epithelial cells were detected with RT-qPCR and Western blot, the cell proliferation was detected with CCK-8 assay, and the activity of Na +-K +-ATPase was also detected. Results:RASAL3 was highly expressed in cholangiocarcinoma tissues and cell lines; Survival analysis showed that RASAL3 overexpression was associated with poor prognosis of cholangiocarcinoma( P<0.05) and knockdown of RASAL3 inhibits the proliferation of cholangiocarcinoma cells; Silencing RASAL3 decreases the expression of FXYD6 inhibiting the activity of Na +-K +-ATPase. Conclusion:RASAL3 is up-regulated in human cholangiocarcinoma, which can promote the occurrence and development of cholangiocarcinoma by activating FXYD6 and affecting Na +-K +-ATPase activity.
ABSTRACT
Objective:To study the risk factors of postoperative permanent hypoparathyroidism after total thyroidectomy.Methods:In this retrospective study ,the receiver operating characteristic (ROC) curve of postoperative 24 h parathyroid hormone(PTH) values was used to predict the risk of permanent hypoparathyroidism.The clinical and pathological features that related to postoperative permanent hypoparathyroidism were studied by χ2 test and multivariate Logistic regression analysis. Results:Eight hundred and eighty-nine patients were enrolled, the incidence of postoperative transient and permanent hypoparathyroidism was 33.3% and 4.0%, respectively. When 24 h PTH levels less than or equal to 5.84 pg/ml were used as cut off value, the sensitivity of the prediction of permanent hypoparathyroidism was 100%, the specificity was 72%, and the positive predictive value was 22.5%. The presence of parathyroid gland in the pathologic specimen, parathyroid autotransplantation and PTH≤5.84 pg/ml at 24 h after operation were statistically significant risk factor for permanent hypoparathyroidism in multivariate analysis( χ2=10.900, P=0.001; χ2=4.415, P=0.044; χ2=13.576, P=0.000). Group analysis found that the lower 24 h PTH the higher incidence of permanent hypoparathyroidism. Conclusions:For patients undergoing total thyroidectomy, when parathyroid gland is involved and/or the PTH value is low at 24 h after surgery, the occurrence of permanent hypoparathyroidism is high.
ABSTRACT
Osteoporosis and chronic psychological stress are two serious chronic degenerative diseases that cause disability and impact population health. Patients with osteoporosis often present with heavier psychological burden, lower quality of life, and frequent symptoms of depression and anxiety. There are potential common pathogenic factors, cellular mechanisms and signaling pathways between them. Considering that the number of patient with these diseases is huge and growing rapidly, it is particularly important to explore the pathogenic link between these two diseases as well as cross-effect therapeutics for osteoporosis and mental health disorders.
ABSTRACT
Objective:To investigate the changes in coronal spino-pelvis alignment in patients with developmental dysplasia of the hip (DDH) and effects of total hip arthroplasty on it.Methods:This study included 48 patients (6 males and 42 females) with DDH who underwent total hip arthroplasty from January 2009 to December 2019 at the Department of Orthopaedics, the PLA General Hospital. The average age of patients was 42.81±10.42 years (range, 22 to 61 years), whose follow-up time was 10.31±2.62 months (range, 3 to 18 months). Eleven cases underwent bilateral hip replacements and 37 cases underwent unilateral hip replacements, which included 13 hips in Crowe I, 7 hips in II, 4 hips in III, 35 hips in IV. The coronal spino-pelvic parameters were measured with all patients, including Cobb angle, coronal balance distance (CBD), sacral obliquity (SO), iliac obliquity (IO), hip obliquity (HO), L 5 obliquity (L 5O) and leg length. Results:The interobserver reliability of IO, SO, HO and L 5O in patients with DDH was 0.965, 0.875, 0.912 and 0.934. The interobserver reliability of IO, SO, HO and L 5O was 0.887, 0.889, 0.892 and 0.907. Thirty-three patients diagnosed with DDH had leg length discrepancy, which the incidence was 69% (33/48). The incidence of scoliosis of patients was 58% (28/48). The incidence of pelvic obliquity was 96% (46/48). The preoperative IO was 6.71°±4.62° and the postoperative IO was 3.52°±3.14°, the difference was statistically significant ( t=4.81, P<0.001). The preoperative SO was 6.38°±5.48° and the postoperative SO was 3.72°±3.38°, the difference was statistically significant ( t=3.91, P<0.001). The preoperative HO was 5.32°±5.83° and the postoperative HO was 3.71°±3.62°, the difference had not statistically significant ( t=1.85, P=0.071). The preoperative L 5O was 6.12°±5.46° and the postoperative L 5O was 4.33°±4.71°, the difference had statistically significant ( t=2.15, P=0.037). The preoperative Cobb angle was 11.05°±10.76° and the postoperative Cobb angle was 6.82°±7.76°, which had a statistically difference ( t=4.07, P=0.001). There is no significant difference of preoperative CBD and postoperative CBD, which was 14.22±10.64 mm vs. 13.73±12.58 mm ( t=0.24, P=0.821). Cobb angle was positively correlated with SO and IO ( r=0.61, P<0.001; r=0.57, P<0.001). Conclusion:Causes coronal pelvic obliquity in patients with DDH included leg length discrepancy and hip dislocation. Coronal pelvic obliquity can lead to compensatory scoliosis, which alters the overall coronal spino-pelvic alignment of patients with DDH. However, they can still maintain coronal balance. Total hip arthroplasty could improve the degree of coronal pelvic obliquity significantly and compensatory scoliosis in patients with DDH.
