Objective:To analyze the clinical features of MDA5 antibody positive dermatomyositis (MDA5-DM) and to provide evidence for early diagnosis and treatment.Methods:From March 2019 to June 2021, 272 patients with anti-MDA5-DM from the Nanjing Medical University myositis-associated interstitial lung disease cohort were enrolled, with 76 patients with anti-synthetase syndrome (ASS) as the control group. The clinical characteristics and the occurrence of interstitial lung disease were analyzed. T-test was used for normally distributed and variance-homogeneous independent samples, Mann-Whitney U test for non-normally distributed data, and chi-square test or Fisher′s exact test for dichotomous variables. Results:Among the 272 anti-MDA5-DM patients, 88.6% (241/272) developed interstitial lung disease (ILD), and 33.8% (92/272) developed rapidly progressive ILD (RP-ILD). The six-month all-cause mortality rate of anti-MDA5-DM patients was 16.9% (46/272), and it was as high as 47.8% (44/92) for those with RP-ILD. Compared with ASS patients, anti-MDA5-DM patients had a significantly higher proportion of males, arthritis, Gottron's sign, heliotrope rash, V-sign, periungual erythema, and skin ulcers ( P<0.05). The levels of ALT, AST, and ferritin were significantly increased ( P<0.05). Compared with non-RP-ILD patients, RP-ILD patients had a significantly higher proportion of males [35.9%(33/92) vs. 23.3%(42/180), χ2=4.79, P=0.029], higher levels of LDH [387 (276, 547) U/L vs. 310 (245, 400) U/L, Z=-3.67, P<0.001], ESR [45.5 (29.25, 63.25) mm/1 h vs. 31.2 (20, 51) mm/1 h, Z=-3.71, P<0.001], CRP [10.9 (4.1, 25.2) mg/L vs. 4.54 (2.58, 9.08) mg/L, Z=-4.97, P<0.001], ferritin [1 340 (650, 2 000) ng/ml vs. 556 (203, 1 186) ng/ml, Z=-4.40, P<0.001], and a higher proportion of anti-Ro52 antibody and anti-MDA5 antibody co-positivity [87.0%(80/92) vs. 52.2%(94/180), χ2=31.87, P<0.001]. Conclusion:Anti-MDA5-DM patients are prone to develop RP-ILD and have poor prognosis.

Objective:To compare hamstring tendon graft (HTG), ligament advanced reinforcement system (LARS), and mixed HTG & LARS ligament in reconstruction of posterior cruciate ligament (PCL).Methods:A retrospective study was conducted to analyze the 59 patients with PCL rupture who had been admitted to Department of Orthopedics, The First Affiliated Hospital of Zhengzhou University for arthroscopic PCL reconstruction between January 2018 and August 2021. The patients were divided into 3 groups: in the HTG group of 21 cases [14 males and 7 females aged (37.8±12.6) years], PCL was reconstructed by HTG; in the LARS group of 20 cases [12 males and 8 females aged (34.3±9.1) years], PCL was reconstructed by LARS; in the mixed group of 18 cases [13 males and 5 females aged (33.2±8.3) years], PCL was reconstructed by the mixed HTG & LARS ligament. The 3 groups were compared in terms of Lysholm knee score, International Knee Documentation Committee (IKDC) score, and laxity disparity between bilateral knees at 1 and 2 years after surgery.Results:There was no statistically significant difference in the preoperative general data between the 3 groups, indicating comparability ( P>0.05). One year after surgery, the mixed group had a significantly higher IKDC score [(90.0±6.5) points] than the HTG group [(78.1±5.7) points] and the LARS group [(84.1±7.3) points], and a significantly higher Lysholm score [(88.9±5.5) points] and a significantly smaller laxity disparity between bilateral knees [(2.8±1.7) mm] than the HTG group [(81.8±4.6) points, (4.7±2.4) mm] ( P<0.05). Two years after surgery, the mixed group had a Lysholm score of (93.0±4.5) points, a IKDC score of (92.5±5.7) points, and a laxity disparity between bilateral knees of (2.3±1.8) mm, all significantly better than those in the HTG group [(88.5±5.5) points, (82.7±5.7) points, and (4.2±2.5) mm] and in the LARS group [(89.0±5.2) points, (86.5±7.3) points, and (3.8±2.2) mm] ( P<0.05). In all the 3 groups, the knee function scores and laxity disparities between bilateral knees at 1 and 2 years after surgery were significantly improved compared with the preoperative values ( P<0.05). Conclusions:Satisfactory clinical outcomes can be obtained after arthroscopic PCL reconstruction using HTG, LARS or the mixed HTG & LARS ligament. However, the mixed ligament as a graft can achieve better clinical efficacy than the other two grafts.

Objective:To summarize the clinical characteristics in of different antibody subtypes in of patients with antisynthetase syndrome (ASS) complicated with interstitial lung disease (ILD).Methods:A retrospective analysis was conducted on 132 ASS-ILD patients at the First Affiliated Hospital of Nanjing Medical University (Jiangsu Provincial People′s Hospital), encompassing a period from December 2019 to June 2023. The data included were basic demographic information, clinical features, laboratory test results, chest computed tomography (CT) scans, and pulmonary lung function tests. Patients were categorized into distinct subtypes based on anti-aminoacyl tRNA synthetase (ARS) antibodies. Statistical analysis was performed using a t-test for comparing means between two samples with equal variance, the Mann-Whitney U test for non-normally distributed continuous data, and the chi-square ( χ2) test or Fisher′s exact test for categorical variables. Results:The most prevalent subtype of anti-synthetase antibody was anti-histidine antibody (Jo-1), accounting for 60 of 132 cases (45.5%), followed by anti-glycine-based tRNA synthetase antibody (EJ) (33/132, 2 5.0%), anti-tRNA synthase antibody (PL-7) (26/132, 19.7%), anti-alanine-based tRNA synthetase antibody (PL-12) (7.6%, 10/132), anti-isoleucine-tRNA synthase antibody (OJ) (3/132, 2.2%). The presence of anti-Ro-52 antibodies was significantly associated with rapidly progressive ILD. In patients with different subtypes of ASS-ILD, the presence of anti-Jo-1 antibodies is was positive in 28 cases (46.7%), and the combination of infection is was more common than in other groups ( χ2=0.15, P=0.047). The group with positive anti-EJ antibodies has had a significant decline in lung function, and cough is was more common in 31 cases (93.9%) than in other groups ( P<0.05); the group with positive anti-PL-12 antibodies has had a more pronounced decline in lung function than other groups ( P<0.05), and fever (7 cases, 70.0%) wais more common than in other groups ( χ2=0.02, P=0.022). Conclusion:Anti-Jo-1, Anti-PL-7, and Anti-PL-12 antibodies were are observed more frequently in patients with ILD. Furthermore, a significant deterioration in lung function was is observed in patients testing positive for anti-PL-12 and anti-EJ antibodies.

Aluminum adjuvants (Alum), approved by the US Food and Drug Administration, have been extensively used in vaccines containing recombinant antigens, subunits of pathogens, or toxins for almost a century. While Alums typically elicit strong humoral immune responses, their ability to induce cellular and mucosal immunity is limited. As an alternative, layered double hydroxide (LDH), a widely used antacid, has emerged as a novel class of potent nano-aluminum adjuvants (NanoAlum), demonstrating advantageous physicochemical properties, biocompatibility and adjuvanticity in both humoral and cellular immune responses. In this review, we summarize and compare the advantages and disadvantages of Alum and NanoAlum in these properties and their performance as adjuvants. Moreover, we propose the key features for ideal adjuvants and demonstrate that LDH NanoAlum is a promising candidate by summarizing its current progress in immunotherapeutic cancer treatments. Finally, we conclude the review by offering our integrated perspectives about the remaining challenges and future directions for NanoAlum's application in preclinical/clinical settings.

Objective:To study the expression characteristics of myocardial strain index after the abnormal origin of the left coronary artery of the pulmonary artery in children was repaired.Methods:The data of 30 children (study group) with abnormal origin of pulmonary artery left coronary artery repair from August 2017 to August 2021 were analyzed. In addition, healthy children during the same period were selected as the control group, and the study group was compared before and after treatment and the control group. Circumferential and radial peak myocardial strain index, post-contraction strain index.Results:The longitudinal, circumferential, and radial overall peak strain indexes of the study group before and after treatment were significantly lower than those of the control group, and the longitudinal, circumferential, and radial overall peak strain indexes of the study group after treatment were significantly higher than those before treatment ( P<0.05); The longitudinal, circumferential, and radial peak strain indexes of the study group before treatment were significantly lower than those of the control group. After treatment in the study group, the middle section of the longitudinal inferior wall, the middle section of the anterior wall, the basal section of the anterior wall, the apex, and the circumferential direction were significantly lower The peak strain index of the basal segment of the inferior wall and the middle segment of the inferior wall was significantly lower than that of the control group; and the longitudinal, circumferential, and radial peak strain indexes of the study group after treatment were significantly higher than those before treatment ( P<0.05); the study group children before treatment Longitudinal, circumferential, and radial PSI indexes were significantly lower than those of the control group. After treatment, the study group was treated in the longitudinal inferior wall, septal apical segment, circumferential inferior wall basal segment, inferior wall middle segment, and radial PSI anterior wall basal segment, apex. The part was significantly higher than that of the control group; and the longitudinal, circumferential, and radial PSI of the study group after treatment were significantly lower than before treatment ( P<0.05). Conclusion:After ALCAPA repair, the overall and regional strain and overall synchronization are improved, indicating that the resting myocardium has recovered, but the strain of certain segments supplied by the abnormal left coronary artery fails to normalize after ALCAPA repair. Persistent myocardial injury is consistent, which can provide some guidance for the prognosis assessment of children with ALCAPA.

OBJECTIVES: Intrauterine adhesions (IUA) refers to the adhesions between the myometrium of the uterine cavity, which is secondary to damage to the basal layer of the endometrium due to trauma or infection. The occurrence of IUA is mainly related to intrauterine operations. Hysteroscopic adhesiolysis (HA) is the standard surgical treatment for IUA. But the recurrence rate of IUA after HA is still high. Importantly, endometrium recovery is difficult, resulting in unsatisfied prognosis for moderate to severer IUA patients. Therefore, it is important to take effective primary preventive measures against the etiology to avoid endometrium damage from medical surgery. In this paper, we discuss and analyze predilection and severer sites of intrauterine adhesions, aiming to provide a basis for how to avoid and reduce injuries during intrauterine operations, such as abortion, dilation and curettage. METHODS: In this study, we retrospectively analyzed the surgical videos of patients who underwent HA for the first time from January 2019 to December 2021 in the Third Xiangya Hospital of Central South University so as to assess the area of adhesions and predilection and severer sites of occurrence of adhesions, and we collected 657 patients who underwent HA for the first time, including 81 patients with total IUA and 576 patients with partial IUA. We counted and analyzed the number and composition ratio of partial IUA patients with severer sites of damage to the lateral wall of the uterine cavity and severerr sites of damage to each segment of the uterine cavity. RESULTS: Among 576 patients with partial IUA, there were 60 patients with no significant difference in the degree of adhesions between the right and left sides, 143 patients with severer adhesions on the left side of the uterine cavity, and 373 patients with severer adhesions on the right side of the uterine cavity. There was a difference in the severity of damage of left and right lateral wall. The proportion of patients with severer adhesions on the right side of the uterine cavity (64.8%) was higher than that of patients with adhesions on the left side of the uterine cavity (24.8%), and there was statistically difference (P<0.05). There was 93 patients with severer adhesions at the fundus or bilateral horn of the uterus, 190 patients with severer adhesions at the middle and upper part of the uterine cavity, 245 patients with severer adhesions at the middle and lower part of the uterine cavity and at the endocervix, and 48 patients with no significant difference in the degree of adhesions in each part. The proportion of patients with severer adhesions at the middle and lower part of the uterine cavity and at the endocervix was higher (42.5%) than those with adhesions in the fundus or bilateral horn of the uterus (16.1%) and in the middle and upper part of the uterine cavity (33.0%), and there were statistically differences (both P<0.05). CONCLUSIONS The predilection site of IUA is the lateral wall of the uterine cavity. The severer adhesions is in the right lateral wall of the uterine cavity, the middle and lower segments and the endocervix, which may be related to the operating habits of the surgeon. Therefore, gynecologists should minimize damage to the lateral wall of the uterine cavity, especially the right lateral wall in performing uterine operations (more attention should be paid by right-handed physicians). Besides, we should pay attention to protecting the middle and lower segments of the uterine cavity and the endocervix, avoiding maintaining negative pressure to withdraw the uterine tissue suction tube from the uterine cavity during abortion procedures to minimize damage.

OBJECTIVES: Intrauterine adhesion (IUA) is mainly caused by intrauterine operations such as pregnancy-related curettage and hysteroscopic surgery, resulting in the trauma to the basal layer of the endometrium. Hysteroscopic adhesiolysis is a crucial step in the comprehensive treatment of IUA, and the most common complication is uterine perforation. More than half of all uterine perforations occur during the hysteroscopy or probe/dilator pass through the internal os. Furthermore, inappropriate surgical procedures may lead to endometrial injury, recurrence or even aggravation of adhesions, and complications such as cervix laceration and false passage formation. This study aims to explore the usage of the hysteroscopic dilatation techniques to dilate the internal os and lower uterine segment, which is via hysteroscopy entering the internal os laterally and swinging, or by directly opening the forceps or scissors and bluntly spreading dissection under direct hysteroscopic vision. By using the hysteroscopic dilatation techniques, we intend to improve the effectiveness and safety of cervical dilation in patients with IUA in the internal os and/or lower uterine segment. METHODS: A total of 282 patients with adhesions in the internal os or lower uterine segment underwent HA in the Third Xiangya Hospital of Central South University from January 2020 to June 2021 were included, ranging from 21 to 46 (33.0±4.8) years old in age and 5 to 12 in the American Fertility Society score. Among them, there were 2 cases of false passage formation caused by traditional dilatation in other hospitals. All patients underwent hysteroscopy with integrated hysteroscopy with 5Fr instrument channel and 4.9 mm outer sheath diameter. The internal orifice of cervix and the lower segment of uterine cavity were dilated under the microscope. After the hysteroscopy entered the uterine cavity, the separation of uterine cavity adhesion and the placement of uterine contraceptive ring or uterine stent into the uterine cavity were performed routinely. Age, surgical records, and surgical videos of all included cases were collected. The success rate of dilation and the incidence of surgical complications were assessed. RESULTS: In all cases, the hysteroscopys successfully entered into the uterine cavity by using the hysteroscopic dilatation techniques without failure and switching to cervical dilators. In the 2 cases of false passage due to previous cervical dilation, the uterine cavity was identified and found successfully under direct hysteroscopic vision. During the whole surgery, the vision was clear, and no complications (such as cervix laceration, false passage formation, uterine perforation or water intoxication) occurred. One to 3 months postoperative hysteroscopy revealed no significant fibrotic stenosis in the internal os and lower uterine segment. CONCLUSIONS The hysteroscopic dilation techniques are a strategy for separation methods that is following structural hierarchy anatomy in the mode of "see and treat" for the adhesion in the internal os and uterine cavity under direct hysteroscopic vision. This method not only has ultrasound guidance, but also has the judgment of structural hierarchy anatomy under direct hysteroscopic vision, so there is less chance of anatomical level judgment error. This method makes full use of the hysteroscopic judgement of the experienced hysteroscopic surgeons, so that surgeons can timely find and avoid re-entering the old false passage caused by previous surgery. The adhesions in the internal os and lower uterine segment were separated by the hysteroscopic dilation techniques. In this way, the damage to the endometrium caused by forced insertion of the hysteroscopy can be avoided. Meticulous separation of adhesions and cervical dilation under direct hysteroscopic vision can effectively reduce the occurrence of surgical complications such as false passage formation, cervical laceration, and uterine perforation. The use of mini-hysteroscopy eliminates the need for preoperative cervical preparation, avoiding associated risks and side effects. Moreover, for patients with adhesions in the internal os and lower uterine segment, preoperative cervical preparation is not effective in cervical dilation, while the hysteroscopic dilation techniques are effective, with higher patient acceptance due to the absence of preoperative cervical preparation. For the skilled hysteroscopic surgeons, the hysteroscopic dilation technique is easy to operate and worthy of clinical application.

OBJECTIVES: At present, hysteroscopic submucosal fibroids resection is mostly performed by hysteroscopic electric resection (hereinafter referred to as electric knife). During the operation, the electrothermal effect could not only damage the endometrial tissues covered by the surface of the fibroid, but also easily damage the endometrial tissues around the fibroid, which is very unfavorable for patients with fertility requirements. In addition, for some special fibroids (located at horn and fundus) or Type II and multiple submucosal fibroids, the traditional electric resection is still very difficult. With the opening of the second-child policy and the urgent desire of patients for fertility, more and more attention is paid to the concept of fertility protection in China. Therefore, hysteroscopic cold knife technology (hereinafter referred to as cold knife) has gradually entered the vision. The cold knife has the advantages of simple operation, such as little trauma and quick postoperative recovery. In this study, the advantages of cold knife in the surgical resection of submucosal fibroids are discussed by comparing the safety and effectiveness between the hysteroscopic cold knife resection (hereinafter referred to as cold knife) and the electric knife resection in the submucosal fibroids. METHODS: The clinical data of 112 patients with submucosal fibroids diagnosed and treated by hysteroscopic surgery at the Third Xiangya Hospital of Central South University from January 2017 to October 2021 were retrospectively analyzed, including preoperative general information (such as age, gravidity, abortion times, the size, location, type and number of submucosal fibroids, preoperative hemoglobin value) and intraoperative conditions [such as intraoperative bleeding, the operation time, residual rates and intraoperative complications (massive bleeding, perforation, water poisoning)]. The patients were divided into a cold knife group and an electric knife group, and there were 40 cases in the cold knife group and 72 cases in the electric knife group. The postoperative complications and the pregnancy outcomes in the 2 groups were followed up by telephone, the follow-up data included postoperative recurrence rate, pregnancy rate, pregnancy mode, and pregnancy outcome. RESULTS: Compared with the electric knife group, the cold knife group had more submucous myomas located in the horn or fundus of the uterus (9.7% vs 25.0%), and more Type II myomas or combined with Type II myomas (26.4% vs 70.0%). However, there were no significant difference in intraoperative bleeding, the operation time, intraoperative complications and the residual rates between the 2 groups (all P>0.05). A total of 98 patients were followed up, including 32 patients in the cold knife group and 66 patients in the electric knife group. Compared with the electric knife group, there were lower postoperative complications in the cold knife group (12.5% vs 37.9%) (P<0.05). Among the 7 patients with multiple submucosal fibroids (the number of fibroids ≥5), there were 4 patients in the electric knife group and 3 patients in the cold knife group. In the electric knife group, the postoperative menstrual volume in the 4 patients was significantly reduced and 3 patients had postoperative fertility requirements, which were all diagnosed as intrauterine adhesion by hysteroscopy and performed further surgery. Later, 2 patients had successful pregnancy, 1 had miscarriage, and 1 had full-term spontaneous labor. However, the menstrual volume of the 3 patients in the cold knife group was not significantly reduced compared with normal menstrual volume, and 2 of them had fertility requirements, and they had natural pregnancy and full term vaginal delivery. There were no significant differences in postoperative recurrence rate, pregnancy rate, pregnancy mode and pregnancy outcome between the 2 groups (all P>0.05). CONCLUSIONS Both the electric knife and cold knife resection are safe and effective methods for the treatment of submucosal fibroids. Compared with electric knife resection, the cold knife resection has fewer postoperative complications and perhaps more advantages in endometrial protection, especially for the patients with fertility requirements, submucosal fibroids located at the fundus or horn of the uterus, Type II submucosal fibroids, and multiple submucosal fibroids.

Objectives:To evaluate the role of pancreas multidisciplinary team(MDT) clinic in the diagnosis of pancreatic diseases,patient compliance with MDT advice,and the impact of MDT on the postoperative survival of patients with pancreatic cancer.Methods:The study included 927 patients(554 males,373 females,aged (58.1±13.3)years (range: 15 to 89 years)) that had visited the pancreas MDT clinic of Zhongshan Hospital from May 2015 to December 2021,and 677 patients(396 males, 281 females, aged (63.6±8.9)years(range: 32 to 95 years)) who underwent radical surgery and with pathologically confirmed pancreatic adenocarcinoma from January 2012 to December 2020,of whom 79 patients had attended the pancreas MDT. The clinical and pathological data were collected and analyzed retrospectively. Diseases were classified in accordance with 2010 WHO classification of tumors of the digestive system and usual clinical practices. The Kaplan-Meier method was used for drawing the survival curve and calculating the survival rate. The univariate analysis was done by Log-rank test and the multivariate analysis was done by COX proportional hazards model. Survival rates were compared using χ 2 test. Results:Among the 927 patients that had visited the MDT clinic,233 patients(25.1%) were referred due to undetermined diagnosis. A direct diagnosis was made in 109 cases (46.8%,109/233) by the MDT clinic, of which 98 were consistent with the final diagnosis,resulting in an accuracy of 89.9%(98/109). The direct diagnosis rate in the recent years(36.6%(41/112),from June 2019 to December 2021) decreased compared to that in the previous years(56.2%(68/121),from May 2015 to May 2019),yet the accuracy in the recent years(90.2%,37/41) was basically the same as before (89.7%,61/68). The rate of compliance of the entire cohort was 71.5%(663/927), with the compliance rate in the recent two and a half years(81.4%,338/415) remarkably higher than that in the previous four years(63.4%,325/512). Patients with pancreatic cancer that attended the MDT exhibited a trend toward longer median postoperative survival than patients that did not attend the MDT,but the difference was not statistically significant(35.2 months vs.30.2 months, P>0.05). The 1-year and 3-year survival rates of patients that attended the MDT were significanly higher than patients that did not attend the MDT(88.6% vs. 78.4%, P<0.05;32.9% vs. 21.9%, P<0.05,respectively),but the 5-year survival rate was not statistically different(7.6% vs. 4.8%, P>0.05). Conclusions:The pancreas MDT clinic is an accurate and convenient way to diagnose intractable pancreatic diseases,and in the recent years the patients′ compliance rate with MDT advice has increased. Pancreatic cancer patients that have attended the MDT have higher 1-year and 3-year postoperative survival rates,but the long-term survival benefits of MDT still needs to be proved by clinical studies on a larger scale.
