【Objective】 To comprehensively explore the serological characteristics of anti-PP1P^k and potential therapeutic strategies for recurrent miscarriage in p-blood type pregnant women. 【Methods】 Neutralization with pigeon egg white and human plasma, disruption of IgM antibodies by 2-mercaptoethanol reagent, and complement adding were conducted. Anti-PP1P^k titers under different processing conditions, media and temperatures were determined, and neutralizing effect of human plasma on anti-PP1P^k and its sensitization complement ability were analyzed. 【Results】 The titers of anti-PP1P^k in saline and column agglutination were 4 and 8, respectively. Low temperature increased titers, while β-mercaptoethanol treatment significantly reduced them. Pigeon egg white partially neutralized anti-PP1P^k antibodies. Human plasma was also capable of reducing anti-PP1P^k titers with neutralization capability surpassing that of pigeon egg white, and there were individual differences in neutralization capability. 【Conclusion】 The anti-PP1P^k was a blend of antibodies encompassing both IgM and IgG types, exhibiting cold reactivity, and having the potential for complement activation. Human plasma emerges as an effective modulator for diminishing the efficacy of anti-PP1P^k. Plasma transfusion holds promise as a therapeutic avenue for addressing recurrent miscarriages in pregnant individuals with the p phenotype.

Sepsis is a complex syndrome caused by multiple pathogens and involves multiple organ failure, particularly spleen dysfunction. In 2017, the worldwide incidence was 48.9 million sepsis cases and 11 million sepsis-related deaths were reported (Rudd et al., 2020). Inflammation, oxidative stress, and apoptosis are the most common pathologies seen in sepsis. Liensinine (LIE) is a bisbenzylisoquinoline-type alkaloid extracted from the seed embryo of Nelumbo nucifera. Lotus seed hearts have high content of LIE which mainly has antihypertensive and antiarrhythmic pharmacological effects. It can exert anti-carcinogenic activity by regulating cell, inflammation, and apoptosis signaling pathways (Manogaran et al., 2019). However, its protective effect from sepsis-induced spleen damage is unknown. In this research, we established a mouse sepsis model induced by lipopolysaccharide (LPS) and investigated the protective effects of LIE on sepsis spleen injury in terms of inflammatory response, oxidative stress, and apoptosis.

BACKGROUND: The clinical features of enthesitis in patients with psoriatic arthritis (PsA) have been reported in some Western countries, but data in China are very limited. This study aimed to describe the characteristics of enthesitis in Chinese patients with PsA and compared them with those in other cohorts. METHODS: Patients with PsA enrolled in the Chinese Registry of Psoriatic Arthritis (CREPAR) (December 2018 to June 2021) were included. Data including demographics, clinical characteristics, disease activity measures, and treatment were collected at enrollment. Enthesitis was assessed by the Spondyloarthritis Research Consortium of Canada (SPARCC), Maastricht ankylosing spondylitis enthesitis score (MASES), and Leeds enthesitis index (LEI) indices. A multivariable logistic model was used to identify factors related to enthesitis. We also compared our results with those of other cohorts. RESULTS: In total, 1074 PsA patients were included, 308 (28.7%) of whom had enthesitis. The average number of enthesitis was 3.3 ± 2.8 (range: 1.0-18.0). More than half of the patients (165, 53.6%) had one or two tender entheseal sites. Patients with enthesitis had an earlier age of onset for both psoriasis and arthritis, reported a higher proportion of PsA duration over 5 years, and had a higher percentage of axial involvement and greater disease activity. Multivariable logistic regression showed that axial involvement (odds ratio [OR] 2.21, 95% confidence interval [CI], 1.59-3.08; P <0.001), psoriasis area and severity index (PASI) (OR: 1.03, 95% CI: 1.01-1.04; P = 0.002), and disease activity score 28-C reactive protein (DAS28-CRP) (OR: 1.25, 95% CI: 1.01-1.55; P = 0.037) were associated with enthesitis. Compared with the results of other studies, Chinese patients with enthesitis had a younger age, lower body mass index (BMI), a higher rate of positive human leukocyte antigen (HLA)-B27, more frequent dactylitis, and a higher proportion of conventional synthetic disease-modifying antirheumatic drugs' (csDMARDs) use. CONCLUSIONS Enthesitis is a common condition among Chinese patients with PsA. It is important to evaluate entheses in both peripheral and axial sites.

Objective: To study the effects of single photon emission computed tomography/computed tomography (SPECT/CT) and magnetic resonance imaging (MRI) in the diagnosis of primary bone tumors. Methods: A total of 104 patients with primary bone tumors in Zibo Central Hospital hospital from January 2016 to January 2018 were enrolled in this study. SPECT/CT and MRI examinations were performed on these patients, and the results of the examinations were compared with the results of surgical pathology. The diagnostic efficacy of the two methods for primary bone tumors were compared. Results: ⑴Results of pathological examination: 70 cases were malignant tumors, and 34 cases were benign tumors; results of SPECT/CT: 72 cases were malignant tumors, and 32 cases were benign tumors; MRI: 76 cases were malignant tumors, and 28 cases were benign tumors; there was no difference between the two methods in the diagnosis of primary bone tumors. ⑵ The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of SPECT/CT were 92.86%, 79.41%, 88.46%, 90.28% and 84.38% respectively, slightly higher than those of MRI (91.43%, 64.71%, 82.69%, 84.21% and 78.57%), but the difference was not statistically significant (P>0.05). ⑶ There was a high consistency between SPECT/CT and MRI in the diagnosis of primary bone tumors (Kappa value=0.613). ⑷ SPECT/CT is more accurate in the diagnosis of osteosarcoma, giant cell tumor, myeloma and fibrous dysplasia, while MRI is more accurate in the diagnosis of osteosarcoma, chordoma, Ewing's sarcoma and schwannoma. Conclusions SPECT/CT fusion imaging and MRI have high sensitivity and accuracy in the diagnosis of primary bone tumors, and the results of the two diagnostic methods have high consistency. SPECT/CT has a high accuracy in the diagnosis of ossification and calcification, while MRI has a high accuracy in the diagnosis of bone tumors in bone soft tissue and nervous system. Therefore, the joint application of the two methods can make up for each other's shortcomings and make the diagnosis of primary bone tumor more accurate.

Objective: To analyze the epidemiological characteristics of acute paraquat(PQ)poisoning in children in southwest Shandong, and the risk factors for pulmonary interstitial fibrosis. Methods: This retrospective study was performed on the clinical data of children with acute PQ poisoning admitted from January 2013 to December 2017 in 12 hospitals in southwest Shandong.All participants were divided into pulmonary interstitial fibrosis group and no pulmonary interstitial fibrosis group on the basis of the chest CT 14 days after poisoning.The epidemiological characteristics and risk factors of pulmonary interstitial fibrosis were analyzed. Results: During the study period, a total of 307 children with acute PQ poisoning were admitted to 12 hospitals, of which 61 (19.87%) were suffering from acute PQ poisoning.Forty-nine cases with complete clinical data were analyzed, including 26 male and 23 female patients poisoned by oral.The age distribution ranged from 8 months to 14 years.Poisoning mainly occured from July to September of each year.The mortality of acute PQ poisoning was 8.2%(4/49), and the incidence of pulmonary interstitial fibrosis in survival patients was 44.4%(20/45). Statistical differences (P<0.05) were found between the pulmonary interstitial fibrosis and no pulmonary interstitial fibrosis, with regard to the times of blood purification, the time from poison exposure to blood purification, the application rate of glucocorticoids, the concentration of PQ in urine, the pediatric critical illness score, the time from poison exposure to gastric lavage, the white blood count at admission, serum creatinine, arterial blood lactate, PaO₂, PaCO₂, and PaO₂/FiO₂; however, there was no significant difference in the proportion of blood purification treatment, the mode of blood purification treatment, alanine aminotransferase, aspartate aminotransferase, urea nitrogen, creatine kinase and troponin.Stepwise logistic regression analysis showed that the time from exposure to poison to gastric lavage(OR=0.683, 95%CI 0.210-2.222)and to blood purification(OR=0.0133, 95%CI 0.004-0.042), the times of blood purification(OR=2.862, 95%CI 1.450-5.648), concentration of PQ in urine(OR=1.435, 95%CI 1.085-1.898), and the use of glucocorticoids(OR=0.190, 95%CI 0.048-0.757) were the risk factors for pulmonary interstitial fibrosis(P<0.05). Conclusion Early gastric lavage and blood purification, increasing the frequence of adminitrating purification appropriately, using low-dose glucocorticoids can reduce the incidence of pulmonary interstitial fibrosis of children with acute PQ poisoning.

OBJECTIVE: To analyze relation of ASXL2 gene mutation with the clinical characteristics, prognosis and C-KIT gene mutation in acute myeloid leukemia (AML) patients with AML1-ETO fusion gene. METHODS: The clinical data of 63 primary AML patients with AML1-ETO fusion gene were collected and retrospectively analyzed. The mutation of ASXL2 gene was directly sequenced by PCR. The clinical characteristics, C-KIT mutation rate and prognosis were compared between the patients with ASXL2 gene mutation (group A) and non-mutation (group B). RESULTS: Among 63 patients, 8 (12.70%) cases of ASXL2 mutation gene was detected. Hemoglobin level in peripheral blood of patients in group A was significantly lower than that in group B (P＜0.01). There was no significant difference in sex, ages proportion of bone marrow blasts, lymph node enlargement, peripheral blood leukocytes count and platelets between the two groups (P＞0.05). The infiltration of central nervous system, liver and spleen was not found in both groups. The expression of CD33 in group A was significantly lower than that in group B (P＜0.05), but the results of other immunophenotype analysis were not significantly different between the two groups (P＞0.05). The remission rate and median survival time were not significantly different between two groups (P＞0.05). The detection rate of C-KIT gene mutation were not significantly different between group A and group B (P＞0.05). CONCLUSION Among AML patients with AML1-ETO fusion gene, ASXL2 gene mutation accounts for a certain ratio, and the peripheral blood hemoglobin concentration and CD33 expression in these patients are often low. At the same time, ASXL2 gene mutation may not be closely related with C-KIT gene mutation.

Objective:To explore the application of mobile medical technology in aquatic rehabilitation assessment for patients with spinal cord injury. Methods:From November, 2017 to April, 2018, 72 patients with spinal cord injury accepted aquatic exercise were randomly divided into control group (n = 36) and experimental group (n = 36). All the patients were assessed with Water Orientation Assessment of Alyn (WOTA), using paper scale for the control group, mobile scale for the experimental group, twice. The time for assessment and for recall was recorded. The accuracy of results and variety between assessment was compared. Results:The time for assessment and for recall was less in the experimental group than in the control group (t > 10.492, P < 0.001), with more accuracy of standard total score, the variety of total score and standard total score (χ² > 4.545, P < 0.05). Conclusion:Compared with the paper-based assessment, the assessment based on mobile technology may improve work efficiency.

Objective: To investigate the effects of stage Ⅰ opening and stage Ⅱ opening of prophylactic ileostomy on postoperative recovery in low rectal cancer. Methods: The prospective study was conducted. The clinical data of 88 patients with low rectal cancer who underwent laparoscopic rectal resection and prophylactic terminal ileostomy in the Affiliated Hospital of Qingdao University from September 2016 to May 2017 were collected. According to random number table, patients undergoing laparoscopic rectal resection combined with prophylactic ileostomy with stage I opening were allocated into experimental group, and patients undergoing laparoscopic rectal resection combined with prophylactic ileostomy with stage Ⅱ opening were allocated into control group. Observation indicators: (1) comparison of postoperative clinical endpoints indices; (2) comparison of postoperative complications; (3) comparison of stress response indices. Follow-up was performed using outpatient examination and telephone interview to detect recovery of patients. The patients were followed up for the first time within 24 hours after discharge and kept in contact with the doctor at any time within 1 week after discharge. The patients were followed up at 2 weeks after discharge in outpatient department and then were followed up by telephone interview once a week within 1 month after operation. Patients returned to hospital if there was any discomfort after discharge, and were re-admitted if necessary. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using the independent sample t test. Repeated measurement data were analyzed using repeated ANOVA. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact propability. Results: Eighty-eight patients were screened for eligibility, including 61 males and 27 females, aged from 44 to 74 years, with an average age of 61 years. There were 45 patients in the experimental group and 40 in the control group, respectively. (1) Comparison of postoperative clinical endpoints indices: the operation time, time to first semiliquid diet, postoperative fever time, quality of life score, duration of hospital stay, and total hospitalization expenses were (122±9)minutes, (5.1±1.6)days, (54±8)hours, 18.6±1.5, (6.7±1.2)days, (53 269±2 888)yuan in the experimental group, and (128±10)minutes, (6.4±2.4)days, (65±7)hours, 17.1±1.3, (8.1±1.4)days, (59 419±1 921)yuan in the control group, respectively. There was no significant difference in operation time or time to first semiliquid diet between the two groups (t=1.716, 1.329, P>0.05). There were significant differences in the postoperative fever time, quality of life score, duration of hospital stay, and total hospitalization expenses between the two groups (t=8.688, 5.850, 3.897, 11.707, P<0.05). (2) Comparison of postoperative complications: the incidence of ileostomy-related complications was 22.2%(10/45) in the experimental group, including 5 cases of ileostomy edema, 2 of fluid and electrolyte imbalance, 2 of fecal dermatitis, 1 of ileostomy infection; the incidence of ileostomy-related complications was 34.9%(15/43) in the control group, including 4 cases of ileostomy edema, 3 of fluid and electrolyte imbalance, 4 of fecal dermatitis, 2 of ileostomy infection, 1 of ileostomy membrane separation, and 1 of ileostomy stenosis; there was no significant difference in the incidence of ileostomy-related complications between the two groups (χ²=1.733, P>0.05). The incidence of system complications was 17.8%(8/45) in the experimental group, including 2 case of acute urinary retention, 2 of incisional infection, 1 of abdominal infection, 1 of pulmonary infection, 1 of urinary infection, 1 of deep venous thrombosis of the lower extremities; the incidence of system complications was 20.9%(9/43) in the control group, including 1 case of acute urinary retention, 1 of incisional infection, 1 of intestinal obstruction, 1 of pulmonary infection, 1 of urinary infection, 1 of deep venous thrombosis of the lower extremities, 1 of anastomotic fistula; there was no significant difference in the incidence of system complications between the two groups (χ²=0.140, P>0.05). There was no death in the two groups. Patients with postoperative anastomotic leakage in the experimental group were recovered and discharged after re-surgical exploration and continuous abdominal irrigation, and the remaining patients were discharged after active conservative treatment. (3) Comparison of stress response indices: from preoperation to postoperative 5 days, the C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) were changed from (2.2±0.7)ng/L to (43.9±12.0)ng/L, from (12.2±1.9)fmmol/L to (11.3±1.4)fmmol/L, from (95±17)ng/L to (107±14)ng/L in the experimental group, and from (2.2±0.8)ng/L to (58.8±10.7)ng/L, from (11.6±1.6)fmmol/L to (12.7±1.3)fmmol/L, from (94±16)ng/L to (117±13)ng/L in the control group, respectively, showing significant differences in the changing trends of CRP, TNF-α, IL-6 between the two groups (F=260.042, 55.428, 120.337, P<0.05). However, the changing trend within groups had interactive effects with time, showing no significant difference (F=3.514, 2.366, 1.864, P>0.05). Conclusion Compared with stage Ⅱ opening, stage Ⅰ opening of prophylactic ileostomy in laparoscopic rectal resection for low rectal cancer is safe and effective, which can reduce postoperative stress response and promote patients′ rehabilitation.

In theory of TCM, the root cause of knee osteoarthritis () is the deficiency of liver and kidney, while the symptoms are involved with multiple damages of muscles, tendons and joints. The exogenous evil of wind, coldness, dampness and heat as well as the blood stasis usually block the meridians and collaterals, which cause the knee osteoarthritis. Professorselects acupoints based on syndrome differentiation, and treats both root cause and symptoms. He attaches importance to thepoints, and takes pain as acupoints. He also treats the lower part of body using the upper acupoints, and treats knees through stimulating the low back. The basic acupoints include the affected Dubi (ST 35), Yinlingquan (SP 9), Yanglingquan (GB 34), Liangqiu (ST 34), Xuehai (SP 10),point (extral) andpoint in the knees and waist. Fengchi (GB 20) and Geshu (BL 17) are added for the symptom of wind; Guanyuan (CV 4) is added for the symptom of coldness; Zusanli (ST 36) is added for the symptom of dampness; Quchi (LI 11) is added for the symptom of heat; Fenglong (ST 40) and Sanyinjiao (SP 6) are added for the symptom of phlegm-stasis; Ganshu (BL 18) and Shenshu (BL 23) are added for the deficiency of the liver and kidney. The technical combination of acupuncture, including needle-knife, fire needle, bloodletting, regular acupuncture, TDP, are applied to regulate the patients' deficiency and excess using the nine-six reinforcing and reducing methods, and pay high attention to the mind regulation. Using this method, the efficacy is significant.
