ABSTRACT

Endometriosis and adenomyosis are two similar gynecological diseases that are characterized by ectopic implantation and the growth of the endometrial tissue. Previous studies have reported that they share a common pathophysiology in some respects, such as a similar cellular composition and resistance to the progestogen of lesions, but their underlying mechanisms remain elusive. Emerging single-cell ribonucleic acid sequencing (scRNA-seq) technologies allow for the dissection of single-cell transcriptome mapping to reveal the etiology of diseases at the level of the individual cell. In this review, we summarized the published findings in research on scRNA-seq regarding the cellular components and molecular profiles of diverse lesions. They show that epithelial cell clusters may be the vital progenitors of endometriosis and adenomyosis. Subclusters of stromal cells, such as endometrial mesenchymal stem cells and fibroblasts, are also involved in the occurrence of endometriosis and adenomyosis, respectively. Moreover, CD8+ T cells, natural killer cells, and macrophages exhibit a deficiency in clearing the ectopic endometrial cells in the immune microenvironment of endometriosis. It seems that the immune responses are activated in adenomyosis. Understanding the immune characteristics of adenomyosis still needs further exploration. Finally, we discuss the application of findings from scRNA-seq for clinical diagnosis and treatment. This review provides fresh insights into the pathogenesis of endometriosis and adenomyosis as well as the therapeutic targets at the cellular level.

ABSTRACT

OBJECTIVE: Increasing evidence has shown that calf muscular vein thrombosis (CMVT) can develop into proximal deep vein thrombosis, even causing pulmonary embolism. However, opinions about the prevalence and risk factors are still controversial. This study aimed to investigate the prevalence and risk factors for CMVT in elderly patients with hip fractures to facilitate their preoperative management. METHODS: We included 419 elderly patients with hip fracture who were treated in the orthopaedic department of our hospital from June 2017 to December 2020. The patients were divided into CMVT and non-CMVT groups based on color Doppler ultrasound screening of the venous system in the lower extremities. Clinical data, such as age, sex, body mass index, time from injury to admission, and laboratory data were collected. Univariate and multivariate logistic regression analyses were performed to determine independent risk factors for CMVT. A receiver operating characteristic curve was used to analyze the predictive effectiveness of the model. Finally, the clinical utility of the model was analyzed using decision curve analysis and clinical impact curves. RESULTS: The prevalence of preoperative CMVT was 30.5% (128/419). Independent predictors of preoperative CMVT identified by univariate and multivariate logistic regression analyses were sex, time from injury to admission, American Society of Anesthesiologists (ASA) classification, C-reactive protein (CRP) level, and D-dimer level (p < 0.05). The area under curve (AUC) was 0.750 (95% CI: 0.699-0.800, p < 0.001) and the sensitivity and specificity were 0.698 and 0.711, respectively, which meant the prediction model has a good efficacy in the prediction of CMVT risk. In addition, the fitting degree of the prediction model was also good (Hosmer-Lemeshow χ2 = 8.447, p > 0.05). The clinical utility of the model was verified using decision curve analysis and clinical impact curves. CONCLUSION: Sex, time from injury to admission, ASA classification, CRP level, and D-dimer levels are independent preoperative predictors of CMVT in elderly patients with hip fractures. Measures should be taken for patients with these risk factors to prevent the occurrence and deterioration of CMVT.

ABSTRACT

Alkaloids are a class of naturally occurring bioactive compounds that are widely distributed in various food sources and Traditional Chinese Medicine. This study aimed to investigate the therapeutic effects and underlying mechanisms of alkaloid extract from Codonopsis Radix (ACR) in ameliorating hepatic lipid accumulation in a mouse model of non-alcoholic fatty liver disease (NAFLD) induced by a high-fat diet (HFD). The results revealed that ACR treatment effectively mitigated the abnormal weight gain and hepatic injury associated with HFD. Furthermore, ACR ameliorated the dysregulated lipid metabolism in NAFLD mice, as evidenced by reductions in serum triglyceride, total cholesterol, and low-density lipoprotein levels, accompanied by a concomitant increase in the high-density lipoprotein level. ACR treatment also demonstrated a profound anti-oxidative effect, effectively alleviating HFD-induced oxidative stress and promoting ATP production. These effects were achieved through the up-regulation of the activities of mitochondrial electron transfer chain complexes I, II, IV, and V, in addition to the activation of the AMPK/PGC-1α pathway, suggesting that ACR exhibits therapeutic potential in alleviating the HFD-induced dysregulation of mitochondrial energy metabolism. Moreover, ACR administration mitigated HFD-induced endoplasmic reticulum (ER) stress and suppressed the overexpression of ubiquitin-specific protease 14 (USP14) in NAFLD mice. In summary, the present study provides compelling evidence supporting the hepatoprotective role of ACR in alleviating lipid deposition in NAFLD by improving energy metabolism and reducing oxidative stress and ER stress. These findings warrant further investigation and merit the development of ACR as a potential therapeutic agent for NAFLD.

ABSTRACT

Background/Aims@#Herbal medicine is an important complementary therapy for functional dyspepsia (FD). However, its effect against gastric hypersensitivity in patients with FD has rarely been evaluated. Yokukansan (YKS), a traditional Japanese herbal medicine, is effective against neuropathic and inflammatory pain. This study aims to use a maternal separation (MS) stress-induced FD model to investigate the effects of YKS against gastric hypersensitivity, gastric motility, and duodenal micro-inflammation. @*Methods@#The MS stress model was established by separating newborn Sprague-Dawley rats from their mothers for 2 hours a day from postnatal days 1 to 10. At the age of 7-8 weeks, the rats were treated with YKS at a dose of 5 mL/kg (1 g/kg) for 7 consecutive days. AfterYKS treatment, electromyographic activity in the acromiotrapezius muscle by gastric distention and the gastric-emptying rate were assessed. Immunohistochemical analysis of eosinophils in the duodenum and phosphorylated extracellular signal-regulated kinase(p-ERK) 1/2 in the spinal cord was performed. @*Results@#YKS treatment suppressed MS stress-induced gastric hypersensitivity and decreased the elevated levels of p-ERK1/2 in the spinal cord.In the gastroduodenal tract, YKS inhibited eosinophil-associated micro-inflammation but did not improve gastric dysmotility. @*Conclusions@#YKS treatment improved gastric hypersensitivity by alleviating eosinophil-associated micro-inflammation in the gastroduodenal tract.This treatment may be considered an effective therapeutic option for epigastric pain and micro-inflammation in patients with FD.

ABSTRACT

OBJECTIVE@#Qili Qiangxin (QLQX), a compound herbal medicine formula, is used effectively to treat congestive heart failure in China. However, the molecular mechanisms of the cardioprotective effect are still unclear. This study explores the cardioprotective effect and mechanism of QLQX using the hypoxia-reoxygenation (H/R)-induced myocardial injury model.@*METHODS@#The main chemical constituents of QLQX were analyzed using high-performance liquid chromatography-evaporative light-scattering detection. The model of H/R-induced myocardial injury in H9c2 cells was developed to simulate myocardial ischemia-reperfusion injury. Apoptosis, autophagy, and generation of reactive oxygen species (ROS) were measured to assess the protective effect of QLQX. Proteins related to autophagy, apoptosis and signalling pathways were detected using Western blotting.@*RESULTS@#Apoptosis, autophagy and the excessive production of ROS induced by H/R were significantly reduced after treating the H9c2 cells with QLQX. QLQX treatment at concentrations of 50 and 250 μg/mL caused significant reduction in the levels of LC3II and p62 degradation (P < 0.05), and also suppressed the AMPK/mTOR signalling pathway. Furthermore, the AMPK inhibitor Compound C (at 0.5 μmol/L), and QLQX (250 μg/mL) significantly inhibited H/R-induced autophagy and apoptosis (P < 0.01), while AICAR (an AMPK activator, at 0.5 mmol/L) increased cardiomyocyte apoptosis and autophagy and abolished the anti-apoptotic effect of QLQX. Similar phenomena were also observed on the expressions of apoptotic and autophagic proteins, demonstrating that QLQX reduced the apoptosis and autophagy in the H/R-induced injury model via inhibiting the AMPK/mTOR pathway. Moreover, ROS scavenger, N-Acetyl-L-cysteine (NAC, at 2.5 mmol/L), significantly reduced H/R-triggered cell apoptosis and autophagy (P < 0.01). Meanwhile, NAC treatment down-regulated the ratio of phosphorylation of AMPK/AMPK (P < 0.01), which showed a similar effect to QLQX.@*CONCLUSION@#QLQX plays a cardioprotective role by alleviating apoptotic and autophagic cell death through inhibition of the ROS/AMPK/mTOR signalling pathway.

ABSTRACT

DNA damage response (DDR) is a highly conserved genome surveillance mechanism that preserves cell viability in the presence of chemotherapeutic drugs. Hence, small molecules that inhibit DDR are expected to enhance the anti-cancer effect of chemotherapy. Through a recent chemical library screen, we identified shikonin as an inhibitor that strongly suppressed DDR activated by various chemotherapeutic drugs in cancer cell lines derived from different origins. Mechanistically, shikonin inhibited the activation of ataxia telangiectasia mutated (ATM), and to a lesser degree ATM and RAD3-related (ATR), two master upstream regulators of the DDR signal, through inducing degradation of ATM and ATR-interacting protein (ATRIP), an obligate associating protein of ATR, respectively. As a result of DDR inhibition, shikonin enhanced the anti-cancer effect of chemotherapeutic drugs in both cell cultures and in mouse models. While degradation of ATRIP is proteasome dependent, that of ATM depends on caspase- and lysosome-, but not proteasome. Overexpression of ATM significantly mitigated DDR inhibition and cell death induced by shikonin and chemotherapeutic drugs. These novel findings reveal shikonin as a pan DDR inhibitor and identify ATM as a primary factor in determining the chemo sensitizing effect of shikonin. Our data may facilitate the development of shikonin and its derivatives as potential chemotherapy sensitizers through inducing ATM degradation.

ABSTRACT

Objective:To investigate the clinical features and long-term prognosis of patients co-existing with ovarian endometrioma (OMA) and deep infiltrating endometriosis (DIE).Methods:Totally 358 OMA patients were retrospectively analyzed, who had a minimum of 8 years follow-up after laparoscopic cystectomy, which was performed by one professional endometriosis surgery team at Peking Union Medical College Hospital from January 2009 to April 2013. All women were divided into DIE group and non-DIE group, and analysis was performed in preoperative characteristics, surgical findings and postoperative outcomes during follow-up.Results:A total of 358 OMA patients were included, of which 190 patients (53.1%, 190/358) were in the DIE group, while other 168 patients (46.9%, 168/358) in the non-DIE group. The average ages between the two groups were (33.7±5.4), (32.5±5.3) years ( P=0.047), the average parity was (0.4±0.6) times vs (0.3±0.5) times ( P=0.079). There were significant differences in the proportions of moderate to severe dysmenorrhea [67.4% (128/190) vs 56.5% (95/168)], chronic pelvic pain [24.2% (46/190) vs 7.7% (13/168)], and the increase in CA 125 [79.9% (139/190) vs 65.2% (101/168)] between the two groups (all P<0.05). The average operation time in the DIE and non-DIE groups was (75±21) vs (39±36) minutes ( P<0.01). There was a significant difference in adenomyosis presence between the two groups [41.6% (79/190) vs 22.0% (37/168); P=0.001]. All patients were followed up for at least 8 years. At the end of the follow-up, though the DIE group was with higher total rate of disease relapse, yet no significant difference was found between the two groups in statistical comparison [21.6% (41/190) vs 16.1% (27/168); P=0.185]. A total of 41 cases in the DIE group recurred, the recurrence rate of pain was 15.8% (30/190), and the recurrence rate of cyst was 8.4% (16/190); 27 cases had recurrence after operation in the non-DIE group, the recurrence rate of pain was 8.9% (15/168), and the recurrence rate of cyst was 10.7% (18/168). There were no significant differences in the pain recurrence rate ( P=0.067) and cyst recurrence rate ( P=0.460) between the two groups. As for the successfully pregnant patients, live birth rates were 100.0% (65/65) vs 94.4% (68/72) between DIE group and non-DIE groups ( P=0.120). Conclusions:Compared with the non-DIE group, OMA patients with concurrent DIE might have severe pain symptoms, higher probability of abnormal CA 125 levels and more severe pelvic adhesions. Although there are no significant differences in the total recurrence rate and the recurrence rate of various types between the two groups, the proportion of pain recurrence in the DIE group is higher than that in the non-DIE group. In terms of fertility outcomes, patients in the DIE group are with lower likelihood of pregnancy after surgery during the long-time follow-up. DIE has no significant influence on the fertility outcome.

ABSTRACT

Objective:To explore the effect of mental model based on relaxation training and 5E rehabilitation model on the perioperative rehabilitation of patients with osteosarcoma, in order to provide the reference for rehabilitation nursing of patients with osteosarcoma.Methods:A total of 142 osteosarcoma patients were selected from January 2018 to December 2019 in the Affiliated Union Hospital of Tongji Medical College of Huazhong University of Science and Technology. According to the random method of digital table, the patients were divided into observation group and control group, 71 cases respectively. The control group took routine nursing, and the observation group patients took the mental model based on relaxation training and 5E rehabilitation mode. The quality of life, the levels of depression and anxiety before and after intervention were evaluated by Karuafsky Functional State Score, Generalized Anxiety Scale (GAD-7) and Health Questionnaire Depression Symptom Group Scale (PHQ-9). The recovery of the affected limb was evaluated by the Musculoskeletal Tumor Society (MSTS).The adverse reactions were observed.Results:There was no significant difference in the quality of life between the two groups before nursing ( P>0.05). After nursing, the quality of life score was (91.10±12.38) points in the observation group and (82.20±12.51) points in the control group. The difference was statistically significant ( t value was 10.441, P<0.001). There was no significant difference in GAD-7 and PHQ-9 scores between the two groups before nursing ( P>0.05). After nursing, the GAD-7 and QPH-9 score were (5.21±3.12), (4.41±3.43) points in the observation group and (6.82±3.34) , (6.43±3.13) points in the control group. The differences were statistically significant ( t values were 9.531, 10.592, P<0.001). The excellent and good recovery rate of the affected limb in the observation group was 71.9%(51/71) in the observation group and 54.9%(39/71) in the control group, the difference was statistically significant ( χ2 value was 10.468, P<0.001). The incidence of adverse reactions was 5.6%(4/71) in the observation group and 12.7%(9/71) in the control group, the difference was statistically significant ( χ2 value was 12.543, P<0.001). Conclusions:The mental model based on relaxation training combined with 5E rehabilitation model can improve the postoperative rehabilitation effect of patients with osteosarcoma limb salvage treatment, so that patients can establish confidence, actively cooperate with treatment and participate in postoperative rehabilitation training. Through intervention, patients can actively adjust their mentality, lay the foundation for further adjuvant treatment, improve the quality of life of patients, and ultimately improve the prognosis.

ABSTRACT

Objective: To investigate the relationship between high sensitivity C-reactive protein (hs-CRP) level and incidence of left atrial spontaneous echocardiographic contrast (LASEC) in the patients with nonvalvular atrial fibrillation (AF). Methods: Four hundred and ninety consecutive patients with nonvalvular atrial fibrillation who underwent radiofrequency ablation for the first time from January 1, 2018 to June 30, 2018 in the Department of Cardiology, Beijing Anzhen Hospital were enrolled. According to the results of transesophageal echocardiography before radiofrequency ablation, patients were divided into the group without LASEC (n=338) and the group with LASEC (n=152). hs-CRP was determined by latex enhanced immunoturbidimetry. The relationship between hs-CRP and LASEC in patients with nonvalvular atrial fibrillation was investigated by univariate and multivariate logistic analysis. Results: LASEC was detected in 152 (31%) of 490 patients. Significant differences in age, type of atrial fibrillation, previous embolic events, fibrinogen, D-dimer, the left atrial anteroposterior diameter and CHA(2)DS(2)-VASc scores were found between patients with and without LASEC (all P<0.05). Compared with the group without LASEC, the serum hs-CRP level was significantly higher in the group with LASEC (3.16 (1.30, 5.23) mg/L vs. 0.67 (0.37, 1.48) mg/L, P<0.001). Multivariate logistic regression analysis showed that hs-CRP (OR=1.136, 95%CI 1.060 - 1.217, P<0.001) and D-dimer (OR=1.040, 95%CI 1.011 - 1.070, P=0.007) were independent determinants for LASEC in this patient cohort. Conclusions: hs-CRP is an independent determinant for LASEC in patients with nonvalvular atrial fibrillation. Inflammation may thus be involved in the formation of prethrombotic state in patients with nonvalvular atrial fibrillation.

ABSTRACT

Objective:To further understand the current status of diagnosis and treatment of endometriosis in China, the implementation of guideline in different levels of hospitals, and the need for continuing education in endometriosis among primary doctors.Methods:The survey was conducted in the form of convenience sampling questionnaire among the Wechat public platform. The doctors were free to participate in the investigation without any reward. All questions answered were assessed as valid questionnaire. The datas were collected on the questionnaire network platform and analyzed by SPSS 19.0.Results:Totally 1 494 valid questionnaires were collected in this survey. 60.17% (899/1 494) of them were from tertiary hospital, and 32.60% (487/1 494) were from grade two hospital. Only the hospitals where 9.97% (149/1 494) participants based opened the specialist clinic for endometriosis. 70.35% (1 051/1 494) of participants said they had read the second edition of guideline for the diagnosis and treatment of endometriosis which published in 2015. The American Society for Reproductive Medicine (ASRM) staging system was adopted in the clinical practices of only 25.03% (374/1 494) participants. And 18.74% (280/1 494) participants used the endometriosis fertility index (EFI) scoring during the laparoscopic surgery for endometriosis with infertility. 45.18% (675/1 494) of participants said they had not attended any academic conference on endometriosis in the past six months. 64.46% (963/1 494) of the participants believed their diagnosis and treatment in practice should be improved and standardized. 87.15% (1 302/1 494) of the participants expressed the hope that more conferences or workshops on endometriosis would be held.Conclusions:At presents, the diagnosis and treatment of endometriosis in China has been greatly improved, but the implementation of guidelines and the new concept is still a long-term job. The specialist clinic are held only in a few hospitals. It’s the expectation and voice of primary doctors to the association to organize the more academic congresses on endometriosis.

ABSTRACT

BACKGROUND@#The clinical trials emerged centromere protein E inhibitor GSK923295 as a promising anticancer drug, but its function in hepatocellular carcinoma (HCC) remain needs to be fully elucidated, especially as chemotherapy after hepatectomy for liver tumors. We aimed to describe anti-HCC activities of GSK923295 and compare its antiproliferative effects on liver regeneration after partial hepatectomy (PH).@*METHODS@#All subjects were randomized to treatment with either vehicle or GSK923295. Antitumor activity of GSK923295 was assessed by xenograft growth assays. The C57BL/6 mice were subjected to 70% PH and the proliferation was calculated by liver coefficient, further confirmed by immunohistochemistry. The proliferation and cell cycle analysis of liver cell AML12 and HCC cells LM3, HUH7, and HepG2 were investigated using the cell counting kit-8 assay and Flow Cytometry. The chromosome misalignment and segregation in AML12 cells were visualized by immunofluorescence.@*RESULTS@#Treatment with GSK923295 induced antiproliferation in HCC cell lines. It also caused delay on HCC tumor growth instead of regression both in a HCC cell line xenograft model and patient-derived tumor xenograft model. With microarray analysis, CENtromere Protein E was gradually increased in mouse liver after PH. Exposure of liver cells to GSK923295 resulted in delay on a cell cycle in mitosis with a phenotype of misaligned chromosomes and chromosomes clustered. In 70% PH mouse model, GSK923295 treatment also remarkably reduced liver regeneration in later stage, in parallel with the mitotic marker phospho-histone H3 elevation.@*CONCLUSION@#The anticancer drug GSK923295 causes a significant delay on HCC tumor growth and liver regeneration after PH in later stage.

ABSTRACT

OBJECTIVE@#To analyze the clinical and laboratory features of psoriatic arthritis (PsA) patients with positive rheumatoid factor (RF) or anti-cyclic citrullinated peptide (CCP) antibody.@*METHODS@#In the study, 77 PsA patients who were hospitalized in the Department of Rheumatology and Immunology of Peking University Third Hospital from January 2007 to June 2019 were enrolled. All the patients met Classification Criteria for Psoriatic Arthritis or Moll or Wright Criteria. Rheumatoid factor (RF) and anti-cyclic-citrullinated peptide (CCP) antibody were tested in these patients. According to whether anti-CCP antibody or RF was detected in serum, all the patients were divided into anti-CCP antibody or RF positive group (15 cases), anti-CCP antibody or RF negative group (62 cases). According to the detection of anti-CCP antibody in serum, all the patients were divided into anti-CCP antibody positive group (7 cases) and anti-CCP antibody negative group (70 cases). Clinical and laboratory data were collected. The differences of clinical and laboratory indicators between the RF or anti-CCP antibody positive and negative PsA patients were compared. Clinical and laboratory indicators between the anti-CCP antibody positive and negative patients were also compared.@*RESULTS@#Among the 77 patients, 15 were RF or anti-CCP antibody positive, of whom 8 were only RF positive and 2 were only anti-CCP antibody positive, and both of RF and anti-CCP antibody were positive in 5 cases. The RF or anti-CCP antibody positive PsA patients were older than those in the negative group [(58.2±14.8) years vs. (46.69±12.27) years, P=0.002]. And metacarpophalangeal joints, elbow joints and shoulder joints were more likely to be involved in RF or anti-CCP antibody positive PsA patients. PsA patients in the anti-CCP antibody positive group were older than those in the negative group [(62.43±14.34) years vs. (47.59±12.75) years old, P=0.005]. The positive rate of RF and serum level of fibrinogen in the anti-CCP antibody positive group were higher than those in the negative group. The PsA patients in the anti-CCP antibody positive group were all polyarthritis, while 68.6% patients in the negative group were polyarthritis, but there was no statistical difference between the two groups. There was no statistical difference in sausage fingers/toes, changes in nails and enthesitis, and bone erosion on radiographs between the RF or anti-CCP antibody positive and negative PsA patients. There was also no statistical difference in sausage fingers/toes, bone erosion on radiographs, and changes in nails and enthesitis between the anti-CCP antibody positive and negative patients.@*CONCLUSION@#RF and anti-CCP antibodies can be detected in the serum of some PsA patients. RF or anti-CCP antibody positive PsA patients were older than those in negative PsA patients. Metacarpophalangeal joints, elbow joints and shoulder joints were more likely to be involved in RF or anti-CCP antibody positive PsA patients. Anti-CCP antibody positive PsA patients were older and had higher levels of RF positive rate and fibrinogen level.

ABSTRACT

Common bile duct (CBD) stones are a frequent problem in Chinese populations, and their incidence is particularly high in certain areas (Wang et al., 2013). In recent years, laparoscopic common bile duct exploration (LCBDE) and endoscopic retrograde cholangiopancreatography (ERCP) have been the main surgical procedures for CBD stones, although each has different advantages and disadvantages in the treatment of choledocholithiasis (Loor et al., 2017; Zhou et al., 2017). For patients with large stones, a dilated CBD, especially concurrent gallstones, LCBDE is the preferred and most economical minimally invasive procedure (Koc et al., 2013). However, a T-tube is often placed during LCBDE to prevent postoperative bile leakage; this is associated with problems such as bile loss, electrolyte disturbance, and decreased gastric intake (Martin et al., 1998). In addition, the T-tube usually must remain in place for more than a month, during which time the patient's quality of life is seriously compromised. Many skilled surgeons currently perform primary closure of the CBD following LCBDE, which effectively speeds up rehabilitation (Hua et al., 2015). However, even in sophisticated medical centers, the incidence of postoperative bile leakage still reaches ≥10% (Liu et al., 2017). Especially for a beginner, bile leakage remains a key problem (Kemp Bohan et al., 2017). Therefore, a safe and effective minimally invasive surgical approach to preventing bile leakage during primary closure of the CBD after LCBDE is still urgently needed.

ABSTRACT

Hepatocellular carcinoma (HCC) is one of the most common types of liver cancer and is the second leading cause of cancer mortality with an estimated 745 500 deaths annually (Jemal et al., 2011). Although new therapeutic modalities including novel chemotherapeutic interventions and targeted therapy have been applied, the prognosis of HCC patients remains unsatisfactory due to the high incidence of intrahepatic and distal metastases (Siegel et al., 2018).

ABSTRACT

Objective@#To analyze the correlation between the Spondyloarthritis Research Consortium of Canada (SPARCC) magnetic resonance imaging (MRI) sacroiliac joint inflammation score (SPARCC score)/structural score (SSS) and the disease activity as well as the functional indexs. The correlation between the MRI score and inflammatory indicators [erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)] in patients with active axial spondyloarthritis (axSpA) before and after treatment was explored. In addition, the contribution of the two MRI scoring method in evaluating conditions was also explored.@*Methods@#According to the inclusion criteria, 24 patients with active axial SpA were recruited and received the recombinant hauman tumor necrosis factor (TNF)-α receptor Ⅱ: IgG Fc fusion protein(rhTNFR:Fc), sulfasalazine and thalidomide for 12 weeks. Subjects were scored at week 0 and 12 by SPARCC/SSS scores. Bath ankylosing spondylitis disease activity index (BASDAI), Assessment of Spondyloarthritis Intemational Society (ASAS)-endorsed disease activity score(ASDAS)-CRP, bath ankylosing spondylitis functional index (BASFI). Bath ankylosing spondylitis metrology index(BASMI), ESR and CRP. The correlation between the SPARCC/SSS scores and that of clinical indicators were analyzed. Paired sample t test, Wilcoxon signedrank test, Spearman correlation analysis and Pearson correlation analysis were used for statistical analysis, and receiver operating characteristic curve (ROC) was used to evaluate the effectiveness of SPARCC score decline as a response to treatment.@*Results@#① Compared with baseline, after 12 weeks treatment, SPARCC scores [(15±4) and(33±10)], BASDAI [(3.2±0.9) and (5.2±1.1)], BASFI [(2.3±0.6) and (4.6±1.0)], BASMI [(2.3±0.7) and (4.1±1.1)], ASDAS-CRP scores [(2.0±0.8) and (3.7±0.9)], ESR [(16±12) mm/1 h and (49±26) mm/1 h], CRP [(7.2±2.8) mg/L and (30.4±19.3) mg/L] were significantly decreased (t values were 7.822, 6.950, 10.707, 7.204, 6.281,-4.015 and-4.257, respectively), and the differences were statistically significant (P=0.000). There was no significant difference in SSS scores between baseline [(20±6) and (19±7)] and after 12 weeks treatment (t=-0.761, P=0.455). ② Before treatment, SPARCC score showed positive linear correlation with BASDAI (r=0.630, P=0.001), ASDAS-CRP (r=0.646, P=0.001), CRP (r=0.574, P=0.003) and ESR (r=0.559, P=0.004), and the correlation of the above indexes disappeared after treatment (P>0.05). The association between SPARCC structral scores and the above indicators was not significant before and after treatment. ③ Areas under curve(AUC) of ROC for assessing treatment response by reduced SPARCC scores was 0.809.

ABSTRACT

Objective To investigate the clinical features of multiple ligament injuries of the knee joint, and evaluate the clinical efficacy of one-stage repair and reconstruction under an arthroscope of multiple ligament injured knee joint. Methods The clinical data were analyzed retrospectively of 22 patients receiving treatment and follow-up for multiple ligament injuries of the knee joint from March 2015 to June 2017 in the Henan Orthopedic Hospital. 13 males and 9 females aged from 24 to 64 years; and left knee injury occurred in 7 cases, right knee in 5 cases, all injuries were close with knee subluxation or dislocation. Imaging, clinical and arthroscopical examination showed anterior and posterior cruciate ligament ruptures in all the patients. The time from injury to operation was from 4 to 16 days, all the patients were treated by single tunnel and single beam reconstruction of anterior and posterior cruciate ligament under an arthroscope, limited incision and reconstruction of PMC (posterior medial complex) and PLC (posterior lateral complex); and the concurrent injuries were treated at that same time. Postoperative X-Ray and MRI were performed to determine the healing of bone tunnel, internal fixation, remodeling of reconstructed tendon and tendon healing. The knee function was assessed on the basis of the range-of-motion of the knee, IKDC score and Lysholm Knee Function score. Results All the patients were followed up from 6 to 14 months with an average of (11.0±1.5) months. The torn inner and outer meniscus and fracture were all healed and the deep venous thrombus was dissolved. Last follow up found varus and valgus stress test was normal or close to normal in 22 patients by Lachman test, anterior and posterior drawer tests were negative, and the tibial shift distance forward or backward was smaller than 5mm. The patients had no subjective symptoms. X-Ray and MRI showed that the tibial femoral tunnel had healed, and the position of internal fixation had no change, and the ligament had been reconstructed and the tendon had healed. In 2 cases, one year later, sensory and motor recovery was observed after common peroneal nerve injury. Range of motion of the knee joint, and Lysholm and IKDC scores were significantly superior at the last following up to at the preoperation (P<0.01); and IKDC comprehensive assessment revealed a normal result (A) in 4 cases, close to normal (B) in 16, abnormal (C) in 2, whereas they are significantly abnormal (D) at admission. Conclusion One-stage arthroscopical repair and reconstruction for multiple ligament injuries of the knee can obviously stabilize the knee joint, improve the knee joint function early, prevent postoperative complications, shorten the hospitalization time, reduce the cost, improve the quality of life, and have the advantages of safety, reliability and less trauma, and the clinical efficacy is satisfactory.
