Objective:To assess the diagnostic value of anti-salivary gland protein-1(SP1)antibody combined with anti-parotid secretory protein(PSP)antibody for Sj?gren's syndrome(SS).Methods:A total of 60 patients with primary SS(pSS)who were treated in the outpatient and inpatient department of Department of Rheumatology and Immunology of the Second Hospital of Hebei Medical University from January 2020 to December 2022 were collected.Thirty patients with other autoimmune diseases accompa-nied by dry mouth and/or dry eyes were collected as disease control group.Thirty healthy subjects from the physical examination center were collected for healthy control group,serum samples were obtained from all of them.Their general features and clinical information including clinical manifestations,labora-tory examinations and other examinations were recorded.The 2016 American College of Rheumatology(ACR)/European League against Rheumatism(EULAR)classification criteria were adopted as the diag-nostic standard of pSS.Immunoglobulin G(IgG)subtype of anti-SP1 antibody and anti-PSP antibody were detected by chemiluminescence immunoassay.The receiver operating characteristic(ROC)curve was used to evaluate the accuracy of anti-SP1 antibody and anti-PSP antibody in diagnosing pSS.The cli-nical characteristics of anti-SP1 antibody and anti-PSP antibody positive patients and negative patients in pSS group were further compared.Independent samples t test,Mann-Whitney U test,variance analysis,Kruskal-Wallis test,Chi-square test or Fisher's exact test and Spearman correlation analysis were used for statistical analysis.Results:There was no significant difference in age(F=1.406,P=0.495)and gender(x2=2.105,P=0.349)among pSS group,disease control group and healthy control group.The expression levels of anti-SP1 antibody(H=16.73,P＜0.001)and anti-PSP antibody(H=26.09,P＜0.001)were statistically different among the three groups.An intergroup comparison of anti-SP1 antibody expression levels showed that there was a statistically significant difference between pSS and healthy con-trol group(P＜0.001),but no statistically significant difference between the other groups.Comparison of anti-PSP antibody expression levels between the groups showed that there were statistically significant differences between pSS and healthy control group(P＜0.001),and between disease control group and healthy control group(P=0.009),while no statistically significant differences between the other groups.The positive rate of anti-SP1 antibody in pSS group was significantly higher than that in disease control group and healthy control group(58.33％vs.40.00％vs.13.33％,P＜0.001).The positive rate of anti-PSP antibody in pSS group was significantly higher than that in disease control group and healthy control group(75.00％vs.56.17％vs.16.67％,P＜0.001).The area under the curve for anti-SP1 antibody was 0.688(P＜0.001).The sensitivity and specificity of anti-SP1 antibody were 58.33％(35/60)and 70.00％(42/60)respectively,the positive predictive value was 66.04％(35/53)and the negative predictive value was 54.55％(42/77)of anti-SP1 antibody.The area under the curve of anti-PSP antibody was 0.720(P＜0.001),with a sensitivity was 75.00％(45/60),and spe-cificity was 63.33％(38/60).The positive predictive value and negative predictive value of anti-PSP an-tibody were 67.16％(45/67)and 71.70％(38/53)respectively.All the 13 pSS patients were negative for anti-Sjogren's syndrome A(SSA,including SSA52 and SSA60)antibody and anti-Sjogren's syn-drome B(SSB)antibody.Among them,11 patients were positive for both anti-SP1 antibody and anti-PSP antibody,1 patient was positive for anti-SP1 antibody and 1 patient was positive for anti-PSP anti-body.The clinical features of anti-SP1 antibody and anti-PSP antibody positive and negative groups were compared in pSS patients.The duration of disease in anti-SP1 antibody positive group was shorter(Z=-2.277,P=0.023)when compared with the negative patients.The patients with positive anti-PSP an-tibody were younger than those in the negative group(t=2.598,P＜0.05),the positive rate of rheuma-toid factor(P=0.002)and the serum level of IgG(t=3.806,P=0.003)in anti-PSP antibody positive group were higher than in the negative group.Analysis of the correlation between anti-SP1 antibody and anti-PSP antibody in the pSS patients showed that there was significant correlation between them(r=0.801,P＜0.001).Conclusion:Both anti-SP1 antibody and anti-PSP antibody are valuable in the diag-nosis of SS,and anti-SP1 antibody is helpful for the early diagnosis of pSS.The combined detection of anti-SP1 antibody and anti-PSP antibody is helpful for the early diagnosis of pSS patients with negative anti-SSA antibody and anti-SSB antibody.

The concept of'harmony'is the soul of traditional Chinese culture,which has a profound impact on the formation and development of traditional Chinese medicine(TCM).TCM is rooted in traditional Chinese culture,and the mode of thinking in TCM is in line with traditional Chinese culture.Based on the harmony culture,TCM has developed a unique view of health,disease and therapeutics.From the view of the harmony culture and by combining with years of clinical experience in treating dermatosis,Chinese medical master XUAN Guo-Wei has applied the concept of'harmony'in the TCM syndrome differentiation and treatment system in clinic,and has developed the academic thoughts of harmonizing therapy for removing toxins for the diagnosis and treatment of dermatosis.The thoughts of harmonizing therapy for removing toxins includes four aspects,namely harmonizing yin and yang,harmonizing healthy qi and pathogenic qi,harmonizing water and fire(i.e.,clod and hot),and harmonizing the administration of formula and drugs,aiming to remove toxins and expel pathogens and value the harmony.The thoughts of harmonizing therapy for removing toxins will beneficial to the comprehensive understanding of the unique health-disease-therapeutics concept in TCM,and will be helpful for managing the doctor-patient relationship,which is of enlightening significance to the modern clinical practice with TCM.

In accordance with the theory of'treating the skin diseases with the skin',skin-related Chinese medicinals are usually used for the treatment of skin diseases,which reflects the thinking mode of holistic syndrome differentiation and classification according to the manifestations in traditional Chinese medicine.With ying-yang theory as the principle of differentiation and treatment of diseases and based on the core pathogenesis of'yin-yang imbalance causing the manifestations of the skin'for the skin diseases,Chinese medical master XU AN Guo-Wei has used skin-related Chinese medicinals in the treatment of skin diseases and has given full play to their unique advantage by following the theory of'treating the skin diseases with the skin'and'balanced regulation of yin and yang'.In the clinical practice,allergic skin diseases were usually treated with Cicadae Periostracum plus Dictamni Cortex for dispelling wind and relieving itching,hypopigmentation related skin diseases were usually treated with Sojae Semen Nigrum skin plus Dictamni Cortex for dispelling wind and tonifying kidney,autoimmune skin diseases were usually treated with Moutan Cortex plus Lycii Cortex for nourishing yin,clearing heat and activating blood,and skin diseases associated with abnormal sebum secretion were usually treated with Mori Cortex plus Lycii Cortex for purging lung and nourishing kidney.Skin-related Chinese medicinals have the actions of expelling wind and promoting eruption of papules,tonifying kidney and nourishing yin.The medication method of'treating the skin diseases with the skin'will provide reference for the treatment of skin diseases.

Objective To explore the influential factors and predictive value of early femoral head collapse progression following allogeneic fibula grafting(AFG)surgery.Methods Clinical and radiological data of 68 patients(75 hips)with osteonecrosis of the femoral head(ONFH)who underwent AFG between January 2008 and December 2022 at the Orthopedics and Traumatology Department,Affiliated Hospital of Nanjing University of Chinese Medicine were retrospectively analyzed.Seventy-five hips were divided into stable(n=40)and progressive(n=35)groups based on the presence or absence of postoperative collapse progression.Age,gender,etiology,location of the lesion,Association Research Circulation Osseous(ARCO)stage,Japanese Committee of Osteonecrosis Investigation(JIC)classification,China-Japan Friendship Hospital(CJFH)classification,and Hounsfield units(HU)value of anterolateral sclerosis rim(ⅠSHU)were collected.Univariate and multivariate logistic regression analyses were used to identify the factors influencing early collapse progression after AFG.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of the identified factors influencing postoperative early collapse progression.Results Of the 75 hips,35(46.7%)had postoperative collapse progression.Univariate logistic regression analysis showed that age,ARCO stage,JIC classification,and ⅠSHU were in fluencing factors for early femoral head collapse progression after AFG(P<0.05).Multivariate logistic regression analysis showed that ARCO stage ⅢA and JIC classification C2 were independent risk factors for early femoral head collapse progression after AFG,while ⅠSHU was identified as an independent protective factor(P<0.05).The ROC curve analysis showed that the sensitivities of ARCO stage,JIC classification,ⅠSHU,and the combined predictive model were 0.850,0.725,0.800,and 0.775,the specificities were 0.486,0.657,0.743,and 0.914,and the area under the ROC curve(AUC)were 0.668,0.725,0.811,and 0.896,respectively.Conclusions ⅠSHU is associated with early collapse progression after AFG in patients with ONFH.ARCO stage ⅢA,JIC classification C2,and ⅠSHU are independent factors influencing postoperative early collapse progression and have a certain predictive value.

Objective:To evaluate the efficacy and safety of antaitasvir phosphate 100 mg or 200 mg combined with yiqibuvir for 12 weeks in patients with various genotypes of chronic hepatitis C, without cirrhosis or compensated stage cirrhosis.Methods:Patients with chronic hepatitis C (without cirrhosis or compensated stage cirrhosis) were randomly assigned to the antaitasvir phosphate 100 mg+yiqibuvir 600 mg group (100 mg group) or the antaitasvir phosphate 200 mg+yiqibuvir 600 mg group (200 mg group) in a 1∶1 ratio. The drugs were continuously administered once a day for 12 weeks and observed for 24 weeks after drug withdrawal. The drug safety profile was assessed concurrently with the observation of the sustained virological response (SVR12) in the two patient groups 12 weeks following the drug cessation. The intention-to-treat concept was used to define as closely as possible a full analysis set, including all randomized cases who received the experimental drug at least once. The safety set was collected from all subjects who received the experimental drug at least once (regardless of whether they participated in the randomization group) in this study. All efficacy endpoints and safety profile data were summarized using descriptive statistics. The primary efficacy endpoint was SVR12. The primary analysis was performed on a full analysis set. The frequency and proportion of cases were calculated in the experimental drug group (antaitasvir phosphate capsules combined with yiqibuvir tablets) that achieved "HCV RNA

Objective To study the relationship between the changes of sagittal spinopelvic parameters and facet joint-derived low back pain in patients with hip osteoarthritis after hip arthroplasty.Methods The clinical data of 30 patients with facet joint-derived low back pain induced by hip osteoarthritis who underwent unilateral hip arthroplasty(observation group)from June 2019 to November 2020 in our hospital were retrospectively analyzed,and 50 healthy subjects who underwent lumbar X-ray examination in the physical examination center of our hospital at the same time were randomly selected as the control group.The sagittal spinopelvic parameters were measured based on the X-ray,including pelvic incidence(PI),pelvic tilt(PT),sacral slope(SS),lumbar lordosis(LL),sacrum pubic incidence(SPI)and sacrum pubic posterior angle(SPPA).The correlation between the changes of sagittal spinopelvic parameters and facet joint-derived low back pain was analyzed by multiple linear regression,and its diagnostic efficacy to facet joint-derived low back pain was analyzed by receiver operating characteristic(ROC)curve.Results The PI,LL,SPI or SPA before and 1 year after surgery of the observation group had no significant difference combined with those of the control group(P>0.05).The PT before surgery of the observation group was smaller than that of the control group(P<0.05),and the SS before surgery was larger than that of the control group(P<0.05).Multiple linear regression analysis showed that PT and SS before surgery were correlated with facet joint-derived low back pain(P<0.05).The sensitivity of PT and SS before surgery in diagnosing facet joint-derived low back pain were 50.00%and 73.30%,with the specificity of 88.00%and 78.00%,respectively.ROC curve analysis showed that the area under the curve of PT and SS before surgery in diagnosing facet joint-derived low back pain were 0.708(95%CI:0.595 to 0.822)and 0.775(95%CI:0.673 to 0.877),respectively.Conclusion Patients with hip osteoarthritis pain have significantly larger SS and significantly smaller PT.Hip arthroplasty can alleviate the symptoms of low back pain without affecting the sagittal spinopelvic balance;the PT and SS before surgery are correlated with the facet joint-derived low back pain,and they are of high value in the diagnosing facet joint-derived low back pain.
