ABSTRACT

Infective nonunion after fracture surgery can cause persistent pain and inflammatory exudate in patients, requiring long-term treatment. To treat infective nonunion, radical debridement of infective bone and soft tissue should be performed, followed by stable internal fixation and bone graft. Multiple treatment strategies need to be considered according to the classification of chronic osteomyelitis, size of the bone defect, degree of bone malalignment, and severity of the soft tissue injury. This paper reports a case of a patient treated with an antibiotic cement-coated nail and a Masquelet technique to treat the infected nonunion of the tibia with a bone defect and varus deformity.

ABSTRACT

Purpose@#Radiocarpal dislocation (RCD), which is caused by high-energy trauma, often involves radial styloid fractures and short radiolunate ligament (SRLL) injuries. Although SRLL injuries may occur as a simple rupture at the attachment site of radius, it may occur with a relatively large avulsed-fragment in the volar rim of the lunate facet of the radius. This study aimed to differentiate the injury type of SRLL and assess the differences in the treatment results depending on the treatment methods that have been applied in RCD with radial styloid fractures. @*Materials and Methods@#Eighteen patients managed surgically with RCD were enrolled in this study. The patients were classified as Group 1 and Group 2 by using the Dumontier method. In this study, Group 2 was subdivided into 2A (purely ligamentous or small avulsion fracture of the volar rim of lunate facet) and 2B (large avulsed-fragment enough to internal fixation) according to the injury type of SRLL.Groups 2A and 2B were treated with direct repair and screw fixation, respectively. Pain, range of motion of the wrist joint, grip strength, and complications on final radiographs were examined. The outcomes were evaluated using patient-rated wrist evaluation (PRWE), and modified Mayo wrist score (MMWS). @*Results@#All patients were Group 2 (six and twelve patients in 2A and 2B, respectively). The mean flexion to extension arch recovered 79%,and the mean grip strength was 72.9% of the uninjured side. Group 2A showed better recovery in extension, flexion and pronation than Group 2B, but there was no difference in radial deviation, ulnar deviation, supination, grip strength and pain. No differences in the PRWE and MMWS were observed between two groups. Complications included traumatic arthritis in seven patients and residual instability in five patients. @*Conclusion@#When the SRLL was injured, the involvement of a large avulsion fracture on the anterior plane of the radiolunate did not affect the test results. On the other hand, it should be observed cautiously because avulsion fractures tend to disturb the joint’s reduction through rotation or displacement. In addition, anatomical reduction and sturdy internal fixation are important for restoring the function of the SRLL.

ABSTRACT

Purpose@#Septic arthritis of the knee is an orthopedic emergency that requires early diagnosis and surgical treatment. This study examined the effectiveness of drain insertion and irrigation in the treatment of septic arthritis of the knee under local anesthesia. @*Materials and Methods@#A retrospective study was conducted on nine cases (eight patients) diagnosed with septic arthritis of the knee from September 2017 to February 2020 and treated with drain insertion and irrigation under local anesthesia. After penetrating through the superolateral portal to the superomedial portal and inserting the drain, daily irrigation of approximately 3 L of normal saline was done. The following were investigated: age, sex, underlying disease, cause, degree of osteoarthritis, time from diagnosis to surgery, duration of hospitalization, duration of normalization of C-reactive protein, and smear and culture. @*Results@#The initial white blood cell count of joint fluid was 71,472±51,667/mm3 (32,400–203,904/mm3 ), and polymorphic leukocytes were 91.1%±2.6% (86%–95%). The average time from diagnosis to surgery was 8.3±1.3 hours (6–10 hours), and the irrigation period was 8.2±3.2 days (4–15 days). The average length of hospitalization was 20.8±8.7 days (9–37 days). There was no reoperation or recurrence. Smear and culture tests were not identified. @*Conclusion@#In the treatment of septic arthritis of the knee, the insertion of a drain tube and irrigation under local anesthesia is a relatively fast and simple method to reduce pain by repetitive draining of purulent joint fluid and can be used as an alternative treatment for patients with a risk of general or spinal anesthesia.

ABSTRACT

Objectives@#The aim of this study is to examine the effect of particulate autogenous tooth graft removed with organic matter and type I collagen addition on bone regeneration and to validate the possibility of useful allograft material for jaw defects.Material and methods: Autogenous tooth bone maker (Korean Dental Solution® KOREA) made particulate autogenous tooth not including organic matter. We used to the developed tooth grafts for experiment. Cell adhesion test with hemacytometer and energy dispersive X-ray spectroscopy (Supra40 VP®, Carl Zeiss, Germany) analysis about the particulate autogenous tooth and type I collagen were performed. Rabbits were divided into three groups: bone graft with organic matter (OM) removing particulate autogenous tooth group, bone graft with OM removing particulate autogenous tooth and type I collagen group, and a control group. Bone grafting was performed in rabbit’s calvaria. The rabbits were sacrificed at different interval at 1, 2, 4, and 6 weeks after bone grafting for the histopathologic observation and observed the effect of bone regeneration by SEM, H-E & Masson stains, osteocalcin IHC staining.Result: In vitro cytopathological study showed affinity for cells, cell attachment pattern, and cell proliferation in the order of control group, OM-removed and collagen-treated group, OM-removed particulate autogenous tooth group. The results of the degree of mineralization were opposite to those of the previous cell experimental results, and the OM-removed group, OM-removed group and collagen-treated group were relatively higher than the control group. Histopathologic analysis showed that vascularization and neonatal bone formation were higher in particulate autogenous tooth group with removing OM and with addition of collagen than control group and group of OM removed only. Immunohistochemical analysis showed that osteocalcin (OSC) expression was not observed in the control group, but at 4 weeks groups, OSC expression was observed the OM removed and OMremoved-collagen-treated particulate autogenous tooth, and the degree of expression was somewhat stronger in group of the OM removed and collagen additionally treated particulate autogenous tooth. @*Conclusion@#Particles that do not contain organic matter, the saint tooth, was responsible for sufficient bone graft material through the role of space maintenance and bone conduction, and further improved bone formation ability through additional collagen treatment. Therefore, research on various extracellular substrates and autologous bone grafting materials is necessary, and through this, it is possible to lay the foundation for a new type of autologous bone grafting material with excellent academic and technical utility.

ABSTRACT

Purpose@#To investigate changes in eye movement amplitude after conjunctival recession and conjunctivo-limbal autograft for treating recurrent pterygium with ocular motility restriction. @*Methods@#We retrospectively analyzed 18 eyes of 16 patients who had recurrent pterygium with ocular motility restriction, who had received conjuntivo-limbal autografts from January 2011 to December 2019 and who had been followed-up for more than 6 months. We evaluated changes in eye movement amplitude, best corrected visual acuity, uncorrected visual acuity, corneal astigmatism and keratometry, and recurrence and complication rates before and after surgery. @*Results@#The mean age of the patients was 63.9 ± 9.7 years. Eye movement amplitude increased significantly from 5.80 ± 1.70 mm preoperatively to 7.02 ± 1.37 mm postoperatively (p < 0.001). The mean UCVA increased from 0.67 ± 0.46 preoperatively to 0.36 ± 0.35 postoperatively (p < 0.001). The mean corneal astigmatism decreased from 3.51 diopters (D) preoperatively to 1.22 D postoperatively (p = 0.001). According to the power vector analysis, M and B were significantly reduced after the surgery, but the changes in J0 and J45 were not significant. No recurrence of pterygium was observed. @*Conclusions@#Eye movement amplitude for severe recurrent pterygium with symblepharon or ocular motility restriction quantitatively measured the range of ocular movement clinically and was applied to determine the severity of recurrent pterygium and predict the surgical outcome. Conjunctivo-limbal autograft for severe recurrent pterygium is thought to be a safe and effective surgical method because it solves the ocular motility restriction caused by adhesions and has low recurrence rates, although it requires the skilled experience and techniques of the operator and a long operation time.

ABSTRACT

Background@#To investigate the clinical and microbiological features of febrile patients with upper urinary tract calculi and factors that affect empirical antibiotic resistance. @*Methods@#A retrospective analysis was performed on 203 febrile patients hospitalized between January 2011 and December 2016 with antibiotic treatment for urinary tract infections and upper urinary tract calculi at three institutions. We collected and analyzed data, including patients' age, sex, body mass index, underlying diseases, stone-related factors, and the results of urine and blood culture examinations and antibiotic sensitivity tests. @*Results@#The male-to-female ratio was 1:2.3. Bacteria were identified in 152 of the 203 patients (74.9%). The most commonly cultured microorganisms included Escherichia coli (44.1%), followed by Enterococci spp. (11.8%), Proteus spp. (8.6%), Streptococcus agalactiae (6.6%), Klebsiella spp. (5.3%), Pseudomonas spp. (4.6%), coagulase-negative Staphylococcus (4.0%), Staphylococcus epidermidis (4.0%), Serratia spp. (2.6%), Enterobacter spp. (0.7%), Acinetobacter spp. (0.7%), and mixed infections (7.2%). Cultured bacterial species showed sex-specific differences. Multivariate analysis revealed that calculi's multiplicity was an independent predictive factor for quinolone resistance (P = 0.008). Recurrent infections were a significant predictor of cefotaxime resistance during multivariable analysis (P = 0.041). @*Conclusion@#Based on the present study results, quinolone was not recommended as the empirical treatment in febrile patients with upper urinary tract calculi. Combination antibiotic therapy is recommended in cases of recurrent infections due to the possible occurrence of cefotaxime resistance.

ABSTRACT

Background@#Although the scallop sign is considered the most important risk factor for extensor tendon ruptures (ETRs) in patients with osteoarthritis of the distal radioulnar joint (DRUJ), previous reports provide a limited understanding of the changes at DRUJ, as risk factors were examined in plain radiographs of the wrist. The aim of this study was to assess the changes of DRUJ using axial images of computed tomography (CT) in patients with DRUJ osteoarthritis and associated ETRs and to evaluate the relationship between the changes of DRUJ and ETRs. @*Methods@#Twelve patients with ETRs due to osteoarthritis of the DRUJ were enrolled. The changes of DRUJ were examined on axial images of CT and the following 8 parameters were measured: width of radius, anteroposterior (AP) length of radius, width of sigmoid notch (SN), AP length of SN, AP length of ulnar head, subluxation length of ulnar head, dorsal inclination of SN, and distance from Lister’s tubercle to SN. Radiological parameters of the DRUJ were measured in 60 control wrists without trauma or osteoarthritis, and the patient and control groups were statistically compared. @*Results@#Statistically significant differences were observed between the patient and control groups in all the radiological parameters except for the AP length of SN and AP length of ulnar head. The width of radius, AP length of radius, width of SN, subluxation length of ulnar head, and dorsal inclination of SN were greater and the distance from Lister’s tubercle to SN was smaller in the patient group than in the control group. The width of SN, dorsal inclination of SN, and distance from Lister’s tubercle to SN were statistically significant risk factors among the 8 parameters. @*Conclusions@#ETRs due to osteoarthritis of the DRUJ was related to the changes of DRUJ, especially the changes around SN of the distal radius. In addition to the existing risk factors, a decreased distance from Lister’s tubercle to SN and increased dorsal inclination of SN were identified as new risk factors. Axial images of CT were effective to evaluate degenerative changes at the DRUJ.

ABSTRACT

The quality control of Chinese herbal medicine is a current challenge for the internationalization of traditional Chinese medicine. Traditional quality evaluation methods lack quantitative analysis, while modern quality evaluation methods ignore the origins and appearance traits. Therefore, an integrated quality evaluation method is urgent in need. Raw Rehmanniae Radix (RRR) is commonly used in Chinese herbal medicine. At present, much attention has been drwan towards its quality control, which however is limited by the existing quality evaluation methods. The present study was designed to establish a comprehensive and practical method for the quality evaluation and control of RRR pieces based on its chemical constituents, appearance traits and origins. Thirty-three batches of RRR pieces were collected from six provinces, while high-performance liquid chromatography (HPLC) was applied to determine the following five constituents, including catalpol, rehmannioside A, rehmannioside D, leonuride and verbascoside in RRR pieces. Their appearance traits were quantitatively observed. Furthermore, correlation analysis, principal components analysis (PCA), cluster analysis and t-test were performed to evaluate the qualities of RRR pieces. These batches of RRR pieces were divided into three categories: samples from Henan province, samples from Shandong and Shanxi provinces, and those from other provinces. Furthermore, the chemical constituents and appearance traits of RRR pieces were significantly different from diverse origins. The combined method of chemical contituents, appearance traits and origins can distinguish RRR pieces with different qualities, which provides basic reference for the quality control of Chinese herbal medicine.

ABSTRACT

Background@#Chromosomal analysis is essential for the diagnosis and risk stratification of all leukemia patients. Not surprisingly, racial differences in chromosomal aberrations (CA) in hematological malignancies could be found, and CA incidence in leukemia might change over time, possibly due to environmental and lifestyle changes. Thus, we compared the frequency and range of CA in patients with acute leukemia (AL) during two time periods (2006‒2009 vs. 2010‒2015) and compared them with other prior studies. @*Methods@#We enrolled 717 patients with AL during a six-year period (2010‒2015). We compared the results to those of our earlier study (2006‒2009) [1]. Conventional cytogenetics, a multiplex reverse transcriptase (RT)-PCR system, and fluorescence in situ hybridization were employed to assess bone marrow specimens or peripheral blood at the diagnostic stage in AL patients to detect CA. @*Results@#The incidence of CA changed in the leukemia subgroups during the two time periods.Notably, the most frequent CA of childhood acute myeloid leukemia (AML) was PML/RARA, and was followed by RUNX1/RUNX1T1 in the current study. In contrast, the most common CA was RUNX1/RUNX1T1 in a previous study [1] and was followed by PML/RARA. In this study, the most frequent CA of the mixed phenotype AL was BCR/ABL1, which was followed by KMT2A/MLLT3. In a previous report, [1] the most frequent CA was BCR/ABL1, which was followed by KMT2A/ELL. @*Conclusion@#The distribution of CA in Korean AL patients changed over time in a single institute. This change might be due to environmental and lifestyle changes.

ABSTRACT

Objective::To observe the clinical efficacy of flavored Sanxitang combined with celecoxib in treating gonarthromeningitis caused by dampness and cold. Method::Totally 120 case were randomly divided into the control group and the treatment group, with 60 cases in each group. The control group was given celecoxib, and the treatment group was treated with flavored sanxitang combined with celecoxib for 30 d. The visual analogue scale (VAS), American knee association knee function scale (AKS), arthritis impact scale (AIMS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were observed before and after treatment. The circumferential diameter, articular cavity effusion and synovial hyperplasia thickness were measured. The serum tumor necrosis factor-α(TNF-α), matrix metalloproteinase (MMP)-3, serum interleukin-1 (IL-1) and erythrocyte sedimentation rate (ESR) were detected. The effective rate and adverse reactions were observed in two groups. Result::The total effective rate in treatment group was 94.8% (55/58), which was higher than 80.7% (46/57) in control group (P<0.05). Compared with before treatment, VAS, AIMS, WOMAC, knee circumference, articular cavity effusion and synovial hyperplasia thickness were significantly reduced in two groups (P<0.05), while the AKS score was significantly increased (P<0.05). Compared with after treatment, VAS, AIMS, WOMAC, knee circumference, articular cavity effusion and synovial hyperplasia thickness were significantly reduced in observation group (P<0.05), whereas the AKS score was significantly increased (P<0.05). TNF-α, MMP-3, IL-1 and ESR in two groups were significantly lower than those group before treatment (P<0.05). After treatment, TNF-α, MMP-3, IL-1 and ESR levels in observation group were significantly reduced compared with those in control group (P<0.05). The incidence rate of adverse reactions in treatment group was 5.89% (4/58), which was lower than 22.81% (13/57) in control group (P<0.05). Conclusion::Flavored Sanxitang combined with celecoxib could alleviate the clinical symptoms of gonarthromeningitis caused by dampness and cold, with a low incidence of adverse reactions.

ABSTRACT

Background@#Prohibitin (PHB) regulates intracellular signal pathways, transcription, and cell cycles. Aberrant expression of the PHB gene is known to be related totumorigenesis, tumor progression, and chronic metabolic and inflammatory diseases. The present study aimed to develop a one-step quantitative reverse transcription PCR (RT-qPCR) kit for quantifying PHB mRNA levels and evaluate its performance in the laboratory. @*Methods@#TaqMan chemistry was used to develop the one-step PHB1 and PHB2 RT-qPCR kit. Normal peripheral blood cells from healthy individuals (N=20) and leukemia cells from patients initially diagnosed with acute myeloid leukemia (AML, N=20), chronic myeloid leukemia (CML, N=13), and acute lymphoid leukemia (ALL, N=7) were enrolled to evaluate the laboratory performance of the kit using commercially available total human RNA controls. @*Results@#The intra-assay and inter-assay precision of the kit developed in this study was less than 2%. The distribution of PHB1 mRNA expression of AML, CML, and ALL was 0.898-0.993 (median: 0.936), 0.817-0.976 (0.918), and 0.844-1.074 (0.973), respectively. The distribution of PHB2 mRNA expression of AML, CML, and ALL was 0.957-1.024 (median: 0.985), 0.988-1.047 (1.002), and 0.937-1.059 (1.004), respectively. The sensitivity, specificity, positive and negative predictive value, and test effectiveness of the developed PHB1 and PHB2 kit were greater than 50% for each parameter. @*Conclusions@#Our developed kit would be useful for diagnosing leukemia as well as detecting residual disease. Additionally, this kit could be used for monitoring and conducting molecular pathophysiological studies of obesity, metabolic, and inflammatory diseases.

ABSTRACT

Objective@#The purpose of this study was to understand the mechanism of normal hyoid movement during swallowing by calculating the activity of each muscle involved in the hyoid movement and propose a new kinetic modeling of hyoid movement using videofluoroscopy images. @*Methods@#Eight healthy volunteers with an average age of 56.8 swallowed 2-ml of diluted barium under videofluoroscopy. A video image was digitized to analyze the movement of the hyoid bone. The activity of the muscles acting on the hyoid bone was calculated from the movement of the hyoid bone using kinetic modeling. A surface electromyogram was measured simultaneously with videofluoroscopy, and the muscle force calculated by kinetic modeling was compared with the muscle force measured by surface EMG. @*Results@#The muscles acting on the hyoid bone were divided into three groups according to the direction of force and analyzed. The contraction of the retractor muscle group was observed as a median of 433 ms (95% CI 264-602, P=0.012) earlier than the contraction of protractor muscle group in all subjects. Generally, the peak activity of each muscle group was observed in the order of retractor (0 ms), protractor (592 ms, 95% CI 429-755), and depressor (717 ms, 95% CI 535-899) muscle group. The contraction of the protractor muscle measured by surface electromyography showed an earlier onset latency with a median of 82 2 ms (95% CI 615-102 9, P=0.012 ) compared to the contraction of the protractor muscle calculated by kinetic modeling. @*Conclusion@#Kinetic modeling reflects the pattern of contraction in the order of retractor, protractor, depressor muscle groups, as previously known. And it was possible to evaluate the activity of the retractor muscle, which is difficult to evaluate by electromyogram.

ABSTRACT

Intramuscular lipomas are benign adipose tumors of the soft tissues that may resemble liposarcomas because of their size, deep location, and occasionally infiltrative growth. An awareness of their existence is fundamental to treating them correctly, and their differential diagnosis from liposarcoma is essential. Magnetic resonance imaging (MRI) is a useful diagnostic tool to differentiate benign adipose tumors from liposarcoma. Marginal excision and biopsy are required for the definite diagnosis and the treatment of symptomatic intramuscular lipomas. To the best of the authors’ knowledge, this is the first report in South Korea regarding the treatment of an intramuscular giant lipoma of the ankle.

ABSTRACT

Purpose@#Given the importance of evaluating the severity of overactive bladder (OAB) symptoms and outcomes after treatment, several questionnaires have been developed to evaluate OAB patients. However, only limited questionnaires are available in Korea for use with Korean patients. Therefore, this study aimed to develop Korean versions of OAB questionnaires through a rigorous linguistic validation process. @*Methods@#The Indevus Urgency Severity Scale, Urgency Perception Scale, Urgency Severity Scale, and Patient Perception of Intensity of Urgency Scale underwent translation and linguistic validation. The linguistic validation procedure consisted of permission for translation, forward translations, reconciliation, back-translation, cognitive debriefing, and proofreading. Two independent bilingual translators translated the original version of each questionnaire, and a panel then discussed and reconciled the 2 initial translations. Next, a third independent bilingual translator performed a backward translation of the reconciled version into English. Five Korean patients diagnosed with OAB were interviewed for cognitive debriefing. @*Results@#Each item of the questionnaires was translated into 2 Korean versions in the forward translation process. Terms such as ‘urgency’ and ‘wetting’ were translated into ordinary language by the translators and adjusted by the panel members to more conceptually equivalent terms in a medical context. In the back-translation process, the panel made a few changes regarding details based on a comparison of the back-translated and original versions. During the cognitive debriefing process, 5 patients provided a few pieces of feedback on the naturalness of the wording of the questionnaires, but generally agreed on the translated terms. @*Conclusions@#In this study, the panel produced a successful linguistic validation of Korean versions of multiple OAB questionnaires, which can be utilized to evaluate the severity and treatment outcomes of OAB.

ABSTRACT

Purpose@#To compare the thickness of the processed pericardial patch graft for glaucoma implant tube coverage using anterior segment optical coherence tomography (AS-OCT). @*Methods@#Thicknesses of seven samples of two pericardial patch grafts (Tutoplast pericardium, IOP Inc, Costa Mesa, CA, USA; pericardium LYO, DCI Donor Services, Inc., Nashville, TN, USA) were measured using AS-OCT (CASIA2, Tomey Corporation, Nagoya, Japan). The thickness of each sample was measured at the center and eight points with 45-degree angular distance, 2 mm from the center. The thickness was measured using AS-OCT program tools. @*Results@#The median thicknesses were 219 μm for Tutoplast pericardium and 157 μm for pericardium LYO. Tutoplast pericardium was significantly thicker than pericardium LYO (p = 0.001); pericardium LYO had a wider interquartile range within each sample, compared to Tutoplast pericardium (p = 0.017). @*Conclusions@#The thickness of the Tutoplast pericardium was greater and less variable than that of the pericardium LYO. These findings should be considered when choosing processed pericardium for coverage of glaucoma implants.

ABSTRACT

Objective@#To investigate the current status of screen time in preschoolers during the outbreak of Corona Virus Disease 2019 (COVID-19), and the influences of parent-child active play and school online education on screen time.@*Methods@#A total of 2 370 preschoolers were chosen through clustering sampling from 7 kindergartens in Wuxi urban areas. Questionnaire survey was administered to parents for child screen time, active play, online education as well as characteristics information.@*Results@#A total of 1 428(60.3%) preschoolers reported more than 1 hour screen time a day, and 1 915(80.8%) preschoolers reported more than 20 minutes consecutive screen time. Compared with the weekend before the COVID-19 outbreak, 1 551(65.4%) preschoolers reported an increase of 10 minutes in screen time perday, and 1 444(60.9%) reported an increase of 5 minutes for one sersion. Logistic regression analysis showed that after controlling for confounding factors, high frequency of parent-child active play, parents’ exercise habits, online education from kindergartens and children’s active participation in the online education were negatively associated with preschoolers’ excessive and increased screen time during this period(OR=0.39-0.79, P<0.05).@*Conclusion@#During the COVID-19 outbreak, preschoolers’ media use in Wuxi city is worrisome. Parent-child active play, parents’ exercise and online education from kindergartens may play a positive role in reducing preschoolers’ media use.

ABSTRACT

Objective:To explore the clinical efficacy of modified Guiling Ganluyin combined with colchicine in treatment of gouty arthritis(GA) damp-heat accumulation. Method:A total of 210 cases of GA were randomly divided into traditional Chinese medicine(TCM) group(70 cases), western medicine group (70 cases), and integrated traditional Chinese and western medicine group(70 cases) according to the digital table method. The patients in TCM group were treated with modified Guiling Ganluyin, the patients in western medicine group were treated with colchicine, and the patients in integrated traditional Chinese and western medicine group received modified Guiling Ganluyin + colchicine, with a treatment course of 30 d in all groups. The clinical symptoms before and after the treatment [joint pain visual analogue scale(VAS), patient global appraise(PGA), number rating scale for pain(NRS)], inflammatory cytokines in serum and joint fluid [tumor necrosis factor-alpha(TNF-α), interleukin-1β(IL-1β), uric acid(UA)], hemorheology index [whole blood high cut viscosity(HCV), whole blood low cut viscosity(LCV), whole blood reductive viscosity(RV)]in 3 groups were observed. The total effective rate and the adverse reactions were compared. Result:Six cases fell off during the study period. The total effective rate in integrated traditional Chinese and western medicine group was 97.1%(67/69), which higher than 80.8%(55/68) in TCM group (χ2=8.153, P<0.05) and 79.1%(53/67) in western medicine group (χ2=8.735, P<0.05). Compared with TCM group and western medicine group, the clinical symptoms VAS and NRS scores in integrated traditional Chinese and western medicine group were significantly lower(P<0.05), while the PGA scores were significantly higher(P<0.05).
