Abstract
Objective: To investigate the pathogenesis and clinical efficacy of arthroscopic treatment for hallux ganglion cyst deriving from ankle joint. Methods: The clinical data of 21 patients with ankle arthroscopic in the Department of Hand and Foot Surgery,Affiliated Hospital of Jining Medical College from January 2019 to March 2021 were analyzed retrospectively.There were 15 male and 6 female cases,aged (52.6±8.2) years (range:42 to 70 years).There were 9 cases of primary operation and 12 cases of recurrence after operation in other hospital.All the patients were examined by ankle arthrography and MRI before operation.The synovial membrane of the ankle was debrided and the tendon sheath of flexor longus was removed at the ankle canal.One year after operation,MRI was performed,and the American Orthopedic Foot and Ankle Society(AOFAS) score of forefoot function and visual analogue scale (VAS) before and after operation were compared by the paired t test or Mann-Whitney U test.The postoperative complications and recurrence were recorded. Results: All patients were operated successfully.The joint capsule at the back of the ankle joint of the patients were ruptured and communicated with the tendon sheath of the flexor longus tendon at the ankle canal.No wound infection,vascular and nerve injury occurred.The follow-up period was (15.0±2.2) months (range:12 to 18 months).During the follow-up period,there was no recurrence of toe appearance and MRI.At the last follow-up,the AOFAS score (90.8±4.3) was significantly higher than that (72.8±6.3) before operation (t=-10.810,P<0.01),and the VAS score(M(IQR)) was significantly lower than that before operation,the difference was significant (1.0(1.0) vs. 3.0(0.5), Z=-4.081,P<0.01). Conclusions: The possible mechanism of hallux ganglion cyst deriving from ankle joint is that the joint capsule at the back of the ankle joint ruptures and communicates with the tendon sheath of the flexor longus tendon at the ankle canal,and the intra-articular synovial fluid through the cylinder effect generated by sliding with the flexor tendon of the flexor longus tendon in the tendon sheath sac leads to the heel valange cyst.Ankle-synovial cleansing of the ankle joint under ankle arthroscopy and resection of the flexor tendon sheath of the flexor longus tendon at the ankle canal are effective and less invasive.

The cytokine profiles in follicular fluid and reproductive outcomes in women with endometriosis. Am J Reprod Immunol 2022; 89:e13633. [PMID: 36250899 DOI: 10.1111/aji.13633] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 09/01/2022] [Accepted: 10/03/2022] [Indexed: 11/26/2022] Open
Abstract
PROBLEM Endometriosis patients undergoing in vitro fertilization-embryo transfer (IVF-ET) treatment suffer from poor oocyte quality, a reduced likelihood of the fertilization rate, and low embryo quality. The dysregulation of immune cells and cytokine profiles in the follicular fluid (FF) may play an important role in the competence of the oocyte and the development of the embryo, but the mechanism remains largely unknown. METHOD OF STUDY A total of 40 proved advanced staged endometriosis patients were enrolled in this study. The pregnancy results were followed until all the embryos collected by the first oocyte retrieval cycle were used up. The immune cells subtypes in FF and serum collected on the day of oocyte retrieval were detected by flow cytometry and 27 cytokines were determined using the Bio-Plex Pro Human Cytokine 27-Plex Immunoassay. The specific effect of cytokine on the gene expression of human granulosa cells was determined by RT-qPCR. RESULTS The fertilization rate and the cumulative live birth rate were significantly lower in the endometriosis group. The ratio of CD4+ /CD8+ T cells in FF was significantly lower, while the level of IP-10, RANTES and G-CSF were statistically higher in the endometriosis group. The level of IP-10 correlated with the IVF outcome. Moreover, treated by IP-10, the mRNA level of FSHR and CYP19A1 the human granulosa cells were downregulated in vitro. CONCLUSION These results suggest that alterations of the lymphocyte subsets and cytokines in women with advanced endometriosis may have an impact on the oocyte development and resulting in poorer IVF outcomes.

Decidual-derived RANKL facilitates macrophages accumulation and residence at the maternal-fetal interface in human early pregnancy. Am J Reprod Immunol 2021; 86:e13406. [PMID: 33629434 DOI: 10.1111/aji.13406] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 01/13/2021] [Accepted: 02/22/2021] [Indexed: 01/18/2023] Open
Abstract
PROBLEM During the first trimester, the accumulation of macrophages, which is the second largest decidual leukocyte population (~20%) at the maternal-fetal interface, is quite vital for a successful pregnancy, including embryo implantation, trophoblast invasion, and vascular remodeling. The mechanism of the enrichment and redistribution of macrophages in the uterine decidua of early pregnancy is largely unclear. METHOD OF STUDY A total of 37 women with normal early pregnancies were included. Primary decidual macrophages (dMφs) (n = 37) and primary decidual stromal cells (DSCs) (n = 37) were isolated, and the adhesion molecules were analyzed by flow cytometry (FCM). Adhesive experiment was carried out to evaluate the adhesion capacity by counting cell numbers of dMφs adhered to DSCs in a co-culture system. RESULTS We found that RANK+ dMφs was the dominating subtype at the maternal-fetal interface. The expression of adhesion molecules (eg, CD29, CD31, CD54, and CD62L) on the surface of RANK+ dMφs was higher than that of RANK- dMφs. After co-culture with DSCs, the expression of adhesion molecules on dMφs was up-regulated in a RANKL-dependent manner. Meanwhile, dMφs promoted the releasing of RANKL on DSCs after co-culture. Consistently, dMφs exhibited the lessoned capacity of adhesion to DSCs when blocking the crosstalk of RANKL-RANK between the DSCs and dMφs in vitro. CONCLUSION These results suggest that the interaction of RANKL-RANK up-regulates the expression of adhesion molecules on the surface of dMφs, contributing to the accumulation and residence of dMφs in human early pregnancy.

Abstract
Objective: To analyze the effect of insufficient intake of vitamin D (VD) on sperm quality and male fertility and to discuss the mechanism of the effect. Methods: VD deficiency mice were fed with VD-deficient diet and light-sheltered. The sperm motility, morphology, ultrastructure, testicular pathology, sex hormones and fertility of normal and VD-deficient mice were analyzed to investigate the effects of VD deficiency on male reproduction. Results: Compared with the normal group, the mice with VD deficiency had lower sperm concentration[(128±53) ×10(6)/ml vs( 58±15) ×10(6)/ml, P<0.05], less sperm in the epididymis, slightly less mature spermatozoa.The serum testosterone[(328±65 )nmol/L vs(255±58 )nmol/L]and estradiol levels[(60±115) pmol/L vs(384±104) pmol/L]were significantly lower (P<0.05), and the FSH[(296±177)ng/L vs(219±105 )ng/L]and LH[(393±129) ng/L vs(364±108) ng/L]levels were significantly higher (P<0.05). The other tests did not show any significant difference (P>0.05). Conclusion: The impact of insufficient intake of VD on sperm quality is not prominent, the specific impact of VD on male reproductive needs to be further studied.

Abstract
OBJECTIVE To investigate the prevalence of Ureaplasma urealyticum (UU) infection in infertile men, its influence on routine semen parameters and the distribution of antisperm antibody (AsAb) and its types in infertile patients with UU infection. METHODS We detected the positive rate of UU infection, semen parameters, and the distribution of AsAb and its types in 662 infertile men and 25 normal fertile male controls followed by comparison of the obtained data between the two groups of subjects. RESULTS The positive rate of UU infection was significantly higher in the infertile men than in the normal controls (52.87% [350/662] vs 16.00% [4/25], χ2 = 11.68, P <0.05). The semen volume, sperm count, sperm concentration and percentage of progressively motile sperm were remarkably lower in the UU-positive infertile males than in the control group (P <0.05). No statistically significant difference was observed between the UU-positive and UU-negative groups in the positive rates of total AsAb (43.4% vs 36.5%, χ2 = 3.25, P >0.05) and AsAb IgA, IgM and IgG in the seminal plasma, or in the percentages of serum AsAb IgM (16.9% vs 20.5%, χ2 = 1.22, P >0.05) and IgG (32.7% vs 28.9%, χ2 = 0.99, P >0.05) except in that of serum AsAb IgA (23.6% vs 17.0%, χ2 = 4.03, P <0.05). CONCLUSIONS The UU infection rate is high in infertile males, which decreases the semen volume, total sperm count, motile sperm concentration and percentage of progressively motile sperm and increases the positive rate of serum AsAb IgA.

Abstract
OBJECTIVE Sperm DNA fragmentation (SDF) is widely used to predict male infertility and the methods of detecting SDF are varied. This study aimed to compare two methods of SDF detection and investigate the correlation between SDF and sperm quality. METHODS Using sperm chromatin structure assay (SCSA) and sperm chromatin dispersion test (SCD), we detected SDF in 108 semen samples collected in the Center of Reproduction and Genetics of Suzhou Municipal Hospital. We compared the results of the two methods and analyzed the correlations of SDF routine semen parameters, sperm morphology and the age of the patients. RESULTS A significant consistency was found in the SDF index (DFI) between the two methods (P<0.01). The DFI was correlated negatively with sperm motility, the percentage of progressively motile sperm, and that of morphologically normal sperm (P <0.01), but positively with the teratozoospermia index (P <0.01 in SCSA and P <0.05 in SCD). The DFI measured by SCSA showed a significantly positive correlation with the patients' age (P <0.01), but not that obtained by SCD. CONCLUSIONS The results of both SCSA and SCD play an important role in predicting sperm quality. As a clinical index, the DFI has a predictive value for male infertility. However, the results of different detecting methods vary widely, which calls for further studies on their standardization.

Abstract
Healing of the inner wall of the same preclotted knitted Dacron arterial prostheses was compared in the descending thoracic aorta (DTA) and the abdominal aorta (AA) of the same dog. Each of 16 dogs received this dual implantation with study periods of 4 weeks for five dogs, 8 weeks for five dogs, and 16 weeks for six dogs. Healing was studied with light microscopy, scanning electron microscopy, transmission electron microscopy, and immunocytochemistry identification. The outer capsule was firmly adherent to the Dacron framework of all grafts implanted in the DTA; advanced healing of the inner wall of all thoracic grafts was present by 4 weeks, nearly complete healing by 8 weeks, and complete healing by 16 weeks. In contrast, the outer capsule was either not attached or only loosely adherent to the Dacron framework in eight AA grafts (50%), and in these implants no healing of the inner wall occurred beyond the limited perianastomotic pannus zone. In the other eight implants in which the outer capsule was firmly adherent to the Dacron framework, healing was roughly comparable to that in the grafts implanted in the DTA. This study demonstrated that (1) DTA grafts heal faster and more completely than AA grafts, (2) healing and endothelialization are related to the tightness of the outer capsule, (3) there is a high incidence of loose tissue attachment in the AA, and (4) healing of aortic grafts is site specific.

Abstract
From 1981 to 1991, 146 infants under 1 month of age underwent repair of aortic coarctation. Forty-two had isolated coarctation, 53 had associated ventricular septal defect, and 51 had complex cardiac defects. The principal mode of presentation was congestive heart failure. The mean age at operation was 10.6 days. The technique for repair was left subclavian artery flap angioplasty in 126, resection with end-to-end anastomosis in 14, and a variety of repairs in 6 patients. Concomitant pulmonary artery banding was performed in 62 patients. The overall hospital mortality rate was 11%, and there was a strong association with pre-existing renal failure. The mean aortic clamp time in survivors was 23.9 minutes; mean hospital stay was 13.4 days. Significant restenosis occurred in 16 patients (11%) with an incidence of 10% after subclavian artery flap angioplasty. Eleven patients have undergone reoperation, and 5 were managed successfully with balloon dilatation.

Abstract
Since 1972, 17 patients have been surgically treated for double aortic arch at our institution. The procedure became necessary before 12 months of age in 11 patients and before 24 months in 16 patients. The major symptoms were respiratory distress, noisy breathing, and respiratory infections; four patients also had dysphagia. A high degree of clinical suspicion should warrant further investigation. Barium swallow and bronchoscopy were diagnostic and revealed extrinsic compression of the esophagus and trachea, respectively. Division of the anterior arch was performed in 16 patients; the right (posterior) arch was divided in the remaining patient. Kommerell's diverticulum was found in four patients and was resected in order to avoid recurrence of dysphagia by compression. A vascular suspension procedure was necessary in 13 patients to further release the trachea and esophagus. There was no mortality in this series, and symptomatic improvement was achieved in all patients. A degree of tracheomalacia may be responsible for some residual symptoms in four patients.

Abstract
Between 1970 and 1988, 12 restrosternal esophageal substitutions using an ileocolic interposition were performed. The ages of the 12 children ranged from 2 to 6 years. In 11 children the esophageal strictures were secondary to ingestion of caustic liquid. All patients had failed esophageal dilation therapy. One death occurred on the 7th postoperative day following an episode of cardiac arrest at surgery. Early postoperative complications included three cervical ileoesophageal anastomotic leaks, which healed spontaneously. One patient had gastrointestinal bleeding 10 years postoperatively. This was controlled by antacid therapy without recurrence. Redundancy of the interpositioned ileocolic segment was observed in three children. All 11 surviving patients can eat a normal diet and have normal growth and development.

Abstract
A child, 2 years old, male suffering from severe jaundice, melena, severe anemia and right upper abdominal mass was admitted into our hospital. Diagnosis of obstructive jaundice was made before operation. On exploration, a tumor mass was found in the pancreatic head, which involved the duodenum and distal common bile duct. Pancreaticoduodenectomy with one stage pancreaticojejunostomy, choledochojejunostomy and gastrojejunostomy was carried out. Postoperative pathology showed adenocarcinoma of the distal common bile duct invading the periampullary tissues of the duodenum and infiltrating, to a lesser extent, into the pancreatic head. Carcinoma arising from the distal common bile duct is rare in infancy and childhood. Radical resection should be attempted if possible. In general, the prognosis is poor in this tumor. No complication after operation occurred on this patient but close follow-up is necessary. Pathology related to this tumor is discussed with a review of literature.

Abstract
Mediastinal masses in children constitute a heterogeneous group of malignant and benign neoplasms. The majority of malignant tumors in our series of 188 children with a mediastinal mass were Hodgkin's and non-Hodgkin's lymphoma (87 patients) arising in the anterior and middle mediastinum. Ganglioneuroma (17) arising in the posterior mediastinum made up the bulk of benign tumors (52). Infants less than 2 yr old presented with symptoms of tracheal compression, whereas older children had fewer symptoms but a far greater likelihood of having a malignancy. In the assessment of patients with mediastinal tumors, the posteroanterior and lateral chest roentgenograms were most often diagnostic, and computed tomography of the chest provided the most information concerning preoperative resectability. The excellent survival of patients with stage I and II Hodgkin's disease reflects the radiosensitivity of the tumor; in our series of 33 patients, survival was not increased by radical resection. Unlike lymphomatous tumors, neurogenic masses should be completely excised. When initial exploration reveals unresectability, biopsy followed by radiation therapy and second-look excision of the tumor can be accomplished. In patients with primary mediastinal sarcomas, total resection should be carried out if possible. In our series, adjuvant radiation therapy or chemotherapy was effective in only 1 of 15 children with sarcoma. Surgical treatment of all mediastinal masses except lymphoma should be complete excision. In cases of suspected lymphoma, cervical or supraclavicular node biopsy can yield adequate tissue for diagnosis.

Abstract
During a 6-yr period, 57 children and young adults less than 21 yr of age underwent 111 thoracotomies for pulmonary metastatic osteogenic sarcoma. Follow-up after the initial thoracotomy averaged 36.8 no and ranged from 1 to 78 mo. Twenty-eight patients (49%) underwent more than one thoracotomy--the number of multiple thoracotomies averaged 2.9 and ranged from two to eight. Twenty-six of the 57 patients are currently alive, and 25 of these are free of disease. Median survival was 36 mo. Actuarial survival curves demonstrated a 5-yr survival of approximately 40%. Seventy-one percent of patients who had a tumor-free interval of greater than 1 yr are currently alive, compared with 39% of patients who had a tumor-free interval of less than 1 yr. Patients with disease confined to one lobe at the initial thoracotomy had a better survival (64%) than patients with diffuse or bilateral disease (41%). An aggressive surgical approach toward osteogenic sarcoma with pulmonary metastasis thus appears to be justified.
