Objective To analyze the correlation of inflammatory indicators of neutrophil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR),monocyte-to-lymphocyte ratio(MLR),and systemic immune-inflammation index(SII)with traditional Chinese medicine(TCM)syndrome types and Chinese version of Thyroid Imaging Reporting and Data System(C-TIRADS)classification and properties of nodules in the patients with thyroid nodules(TN),thus to provide evidence for guiding TCM syndrome differentiation and treatment,and for assessing C-TIRADS classification and properties of the nodules in patients with TN.Methods A retrospective analysis was carried out in 140 inpatients who were diagnosed as TN and had underwent thyroidectomy during the period of January 2021 to January 2024 in the Department of General Surgery of Guangzhou Integrated Chinese and Western Medicine Hospital Affiliated to Guangzhou University of Chinese Medicine(Guangzhou Hospital of Integrated Traditional and West Medicine).The patients were allocated to various group with reference to TCM syndrome types,C-TIRADS classification,and the properties of TN.The correlation of each clinical indicator with TCM syndrome types and C-TIRADS classification and properties of TN was analyzed.The Spearman correlation coefficient was employed for evaluating the correlation of clinical indicators with the C-TIRADS classification and properties of TN,receiver operating characteristic curve(ROC)was used to analyze the predictive value of NLR,MLR,PLR,and SII for the properties of nodules in patients with TN,and the Youden's Index was used to determine the cutoff value for optimal prediction.Results(1)According to the criteria of TCM syndrome differentiation,72 cases were differentiated as qi stagnation and phlegm obstruction syndrome,65 cases as phlegm accumulation and blood stasis syndrome,and 3 cases as heart-liver yin deficiency syndrome.For the number of cases of heart-liver yin deficiency syndrome was too small,only the first two syndromes were included for the analysis.(2)The levels of free T3(FT3)and free T4(FT4)in the patients of qi stagnation and phlegm obstruction syndrome were higher,and the levels of anti-thyroid peroxidase antibody(A-TPO),anti-thyroglobulin antibody(A-TG),neutrophil(NEU),NLR,and SII were lower than those in the patients of phlegm accumulation and blood stasis syndrome,the differences being all statistically significant(P<0.05 or P<0.01).(3)The levels of NLR,PLR,and SII in the patients with C-TIRADS3 classification were lower than those in the patients with C-TIRADS4 classification,the differences being all statistically significant(P<0.05 or P<0.01);no statistically significant difference of MLR was presented between the patients with C-TIRADS3 classification and those with C-TIRADS4 classification(P>0.05).(4)The levels of NLR,PLR,MLR,and SII in patients with benign nodules were lower than those in patients with malignant nodules,the differences being statistically significant(P<0.05 or P<0.01).(5)The Spearman correlation analysis showed that NLR,PLR,and SII were positively correlated with the C-TIRADS classification of the nodules,and NLR,PLR,MLR,and SII were positively correlated with the properties of the nodules,the differences being all statistically significant(P<0.05 or P<0.01).(6)The levels of NLR,MLR,PLR,and SII in patients with high-risk TN exerted a certain predictive value for the properties of the nodules,and their area under the curve(AUC)was 0.645,0.641,0.604,and 0.716,respectively,the differences being statistically significant(P<0.05 or P<0.01).For the prediction of nodule properties by NLR,MLR,PLR,and SII levels in patients with high-risk TN,their cutoff values and the corresponding sensitivities and specificities were 2.261(0.551,0.791),138.108(0.735,0.527),5.132(0.714,0.495),493.114(0.776,0.615),respectively;and their Youden's Index was 0.342,0.262,0.209,0.391,respectively.Conclusion The results indicated that in patients with TN,the FT3 and FT4 levels are positively correlated with the qi stagnation and phlegm obstruction syndrome;the values of A-TPO,A-TG,NEU,NLR,and SII are positively correlated with the phlegm accumulation and blood stasis syndrome;NLR,PLR and SII values are positively correlated with C-TIRADS classification;NLR,PLR,PLR,SII values are positively correlated with malignant TN.NLR,MLR,PLR,SII values exert high efficiency for the prediction of the properties of nodules in patients with TN.

Folic acid is a fully oxidized synthetic folate with high bioavailability and stability which has been extensively prescribed to prevent congenital disabilities. Here we revealed the immunosuppressive effect of folic acid by targeting splenic marginal zone B (MZB) cells. Folic acid demonstrates avid binding with the Fc domain of immunoglobulin M (IgM), targeting IgM positive MZB cells in vivo to destabilize IgM-B cell receptor (BCR) complex and block immune responses. The induced anergy of MZB cells by folic acid provides an immunological escaping window for antigens. Covalent conjugation of folic acid with therapeutic proteins and antibodies induces immunological evasion to mitigate the production of anti-drug antibodies, which is a major obstacle to the long-term treatment of biologics by reducing curative effects and/or causing adverse reactions. Folic acid acts as a safe and effective immunosuppressant via IgM-mediated MZB cells targeting to boost the clinical outcomes of biologics by inhibiting the production of anti-drug antibodies, and also holds the potential to treat other indications that adverse immune responses need to be transiently shut off.

In recent years, traditional Chinese medicine (TCM) has made great progress in the prevention and treatment of cancer. It has gradually revealed its characteristics and advantages in clinical practice, including alleviating clinical symptoms, prolonging survival time, decreasing the adverse effects of chemotherapy, and improving living quality. However, clinical TCM treatment of cancer lacks systematic theoretical guidance, because ancient TCM has not formed a recognized theoretical system of cognitive cancer, and there still are different opinions on the pathogenesis of cancer. Due to the complexity of cancer, the essence of cancer pathogenesis has not been described accurately by using common pathogenic factors, such as pathogenic wind, cold, dampness, summer heat, dryness, and fire. Ancient and modern TCM physicians have a similar understanding that the occurrence of cancer is related to toxin. In the 1990s, the thought of cancerous toxin was first proposed by Prof Zhou Zhongying, a TCM master based on more than 60 years of clinical practice, who used “pandemic Qi (Li-Qi) is a specific pathogenic factor of epidemic disease” in Wenyi Lun (Treatise on Pestilence) for references. The pathogenesis theory of cancerous toxin was gradually established under the guidance of the thought of cancerous toxin. It holds that the cancerous toxin, a special pathogenic factor of cancer, is the key pathogenesis of the occurrence of malignant tumors. According to the pathogenesis theory of cancerous toxin, the basic pathogenesis of malignant tumors is the accumulation of pathogenic factors and cancerous toxin, and the deficiency of the vital Qi (Zheng-Qi). Therefore, the treatment principle involves eliminating pathogenic factors, resolving cancerous toxin, and supporting the vital Qi. The anticancer detoxification methods and the classification of Chinese medicinal herbs with anticancer detoxification effects were put forward. System theory has much in common with the concepts in the theory system of TCM, such as the universal relation theory, asking for a concrete analysis of concrete conditions, the humanism thought, and so on. This article aims to describe, review, and analyze the pathogenesis theory of cancerous toxin based on system theory for clinical practices.

Objective In the recovery process of stroke patients, the ability of maintaining standing and sitting position might have a great effect on the improvement of activity of daily living. There are few the methods which evaluate quantitatively and effectively the ability of position control ability in clinical practice. The aim of the study is to quantitatively evaluate the reliability of posturographic parameters based on the center of pelvis in different standing positions and walking activity.Methods From May to June, 2018, Seventy-nine healthy participants were enrolled. They were evaluated with iReGo, a walking assisstant robot, in three conditions: normal standing position, left/right standing position and walking 10 meters at an appropriate speed. The computer calculated the posturographic parameters automatically. The participants completed their second test one day after the first one.Results During normal standing position, the intra-class correlation coefficients (ICC) of average sway in coronal plane, average sway in sagittal plane, path length, and covered area were more than 0.70. During left standing position, ICC of all the above parameters were more than 0.70. During right standing position, ICC of all the above parameters were more than 0.49. When walking 10 meters at an appropriate speed, ICC of path length and covered area were more than 0.75. Comparing different standing positions, the normal standing position was more stable than the left/right standing position, and there was no difference between the left and the right standing positions.Conclusion Posturographic parameters based on the center of pelvis might be a reliable way to assess the position control ability in different standing positions and walking process.

BACKGROUND:Considering the risk of lack of bone in revision and the bone coverage of component,it is advisable to use bone grafting to increase bone stock in patients with adult Crowe type Ⅲ developmental dysplasia of the hip (DDH) in the first total hip arthroplasty (THA).OBJECTIVE:To investigate the effectiveness of impaction bone grafting with morselized bone and bone paste for acetabular defects of adult Crowe type Ⅲ DDH in THA.METHODS:Forty cases (45 hips) of Crowe type Ⅲ DDH were enrolled,including 8 males and 32 females,aged 31-68 years.All the components were reconstructed at the anatomic acetabulum combined with deepening acetabulum and putting the centre of rotation medially and distally during THA procedures.The patients were all followed up and evaluated with Harris score,limp length,displacement of the centre of rotation,cup coverage,and postoperative complications.RESULTS AND CONCLUSION:The average follow-up was 32.7 months.Acetabular rotation centers of all the cases were recovered (near) to normal.The incisions healed by first intention and there was no complication such as infection,dislocation,prosthesis loosening.The acetabular cup prosthesis did not displace and was covered well by bone at the last follow-up,the grafted bone particles got radiological osseointegration and the bone sclerosis zone disappeared.No radiolucent lines and screw fracture were detected.The Harris scores of affected hips at the last follow-up were significantly higher than those before surgery(P=0).The average leg length was increased (2.31 ±0.18) cm.The mean cup coverage was 78.1％.The postoperative horizontal and vertical distance of the hip center were shorter than those before surgery (P=0).Reconstructing the acetabulum with autogenous morselized bone graft impaction can effectively restore the acetabular coverage,maintain the stability of acetabular cup and provide better relative bone stock in THA for Crowe type Ⅲ DDH in adult,and moreover,the short-term effect is satisfactory.

BACKGROUND:Legacy posterior stabilized prosthesis has advantages in theoretic design,in vitro kinematics and abrasion, but it remains unclear whether its clinical outcomes for vaglus knee deformity are better than Legacy constrained condylar knee prosthesis. OBJECTIVE:To explore the midterm folow-up effect of Legacy posterior stabilized prosthesis in total knee arthroplasty in patients with valgus knee deformity. METHODS: From February 2006 to November 2013 in Department of Bone and Joint Surgery, Affiliated Hospital of Luzhou Medical Colege, total knee arthroplasty was used to treat valgus knee deformity in 33 cases (35 knees). Parapatelar medial approach was used. Precise osteotomy was utilized to correct limb alignment. Lateral soft tissue received selective release. Finaly, an equal type of Legacy posterior stabilized prosthesis (Zimmer, USA) was implanted and fixed with antibiotic bone cement. The differences in hospital for special surgery knee score, range of motion of knee, femoral tibial angle, and maximum flexion and extension angle, as wel as X-ray film results were compared and analyzed before and after replacement. The complications including deep vein thrombosis, peri-prosthetic infection, patelar clicking, unstable knee, and common peroneal nerve injury were recorded after surgery. RESULTS AND CONCLUSION: Al patients were folowed up for 24-50 months. The incision was healed in one-stage. No complications such as peri-prosthetic infection appeared. Three patients suffered from common peroneal nerve palsy, which was cured at half a year after surgery by expectant treatment such as trophic nerve. Two cases suffered from knee instability after replacement, which was improved at 1 month after external fixation with a brace. One case experienced deep vein thrombosis in the lower extremity, which was improved after treatment with low molecular weight heparin anticoagulation. During final folow-up, hospital for special surgery knee score increased from (51.85±4.15) preoperatively to (85.77±2.50) postoperatively (P < 0.01). There were excelent in 20 knees, good in 11 knees, with an excelent and good rate of 89%. X-ray films showed that hindlimb alignment was apparently corrected, prosthetic position was good, no loosening occurred. These data indicate that total knee arthroplasty, using parapatelar medial approach, obtained good correction outcomes through the accurate amputation to correct hindlimb alignment and selective release of the soft tissue with Legacy posterior stabilized prosthesis in the treatment of valgus knee deformity.

OBJECTIVETo investigate the clinical effect of Halo-vest head ring in the treatment of replantation of total scalp avulsion.

METHODSWe treated 11 cases of total scalp avulsion with the anastomosis of arteriovenous vessels and Halo-vest head ring from December 2006 to February 2015.

RESULTSOne patient's replanted scalp got necrosis because of serious contusion which was healed without hair growth after free skin graft and dressing. All the scalp flaps in the other 10 patients survived. After 3-96 months follow-up, the wound completely healed, the scalp and hair grew well with satisfactory appearance.

CONCLUSIONSThe use of Halo-vest head ring for replantation of total scalp avulsion can effectively improve the survival rate and survival area.
