Abstract
BACKGROUND Combined tumors comprising large-cell neuroendocrine carcinoma and hepatocellular carcinoma have been rarely reported in the literature. CASE SUMMARY We report a case of a 73-year-old woman with chronic hepatitis B suspected to have a malignant hepatic mass (segment 3; size, 4.5 cm) and lymph node metastasis based on computed tomography and magnetic resonance imaging. Despite being Child-Pugh class A, esophageal varices were present. She underwent left lateral sectionectomy and lymph node dissection. Pathological examination revealed a collision tumor consisting of large-cell neuroendocrine (90%) and hepatocellular (10%) carcinomas. The combined carcinoma had metastasized to one of the three lymph nodes excised. The patient recovered without any postoperative complications and was discharged in good condition on postoperative day 13. Adjuvant chemotherapy was not performed. No recurrence occurred during a follow-up period of 24 mo. CONCLUSION To improve the therapeutic management of combined tumors in the liver, it is necessary to discuss each clinical experience and consider an appropriate method for the preoperative diagnosis and treatment.

Abstract
We performed a literature mini-review of the clinical profile of patients with spondylarthritis who are also human leukocyte antigen (HLA)-B51-positive. It seems to us that patients with HLA-B27 and HLA-B51 are more common in men, Asians and between the third and ninth decades of life. They are more likely to develop peripheral joint conditions, with cutaneous manifestations (e.g., oral ulcers) and uveitis. Therefore, more robust epidemiological studies with more accurate methodology and multicenter locations are needed to better map the role of the interaction between HLA-B51 in patients with spondylarthritis.

Abstract
When the coronavirus disease 2019 (COVID-19) pandemic spread globally from the Hubei region of China in December 2019, the impact on elderly people was particularly unfavorable. The mortality associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was highest in older individuals, in whom frailty and comorbidities increased susceptibility to severe forms of COVID-19. Unfortunately, in older patients, the course of COVID-19 was often characterized by significant cardiovascular complications, such as heart failure decompensation, arrhythmias, pericarditis, and myopericarditis. Ensuring that the elderly have adequate therapeutic coverage against known cardiovascular diseases and risk factors is particularly important in the COVID-19 era. Beta blockers are widely used for the treatment and prevention of cardiovascular disease. The clinical benefits of beta blockers have been confirmed in elderly patients, and in addition to their negative chronotropic effect, sympathetic inhibition and anti-inflammatory activity are theoretically of great benefit for the treatment of COVID-19 infection. Beta blockers have not been clearly shown to prevent SARS-CoV-2 infection, but there is evidence from published studies including elderly patients that beta blockers are associated with a more favorable clinical course of COVID-19 and reduced mortality. In this minireview, we summarize the most important evidence available in the literature on the usefulness of beta blocker therapy for older patients in the context of the COVID-19 pandemic.

Abstract
BACKGROUND Acute iatrogenic colorectal perforation (AICP) is a serious adverse event, and immediate AICP usually requires early endoscopic closure. Immediate surgical repair is required if the perforation is large, the endoscopic closure fails, or the patient's clinical condition deteriorates. In cases of delayed AICP (> 4 h), surgical repair or enterostomy is usually performed, but delayed rectal perforation is rare. CASE SUMMARY A 53-year-old male patient underwent endoscopic submucosal dissection (ESD) at a local hospital for the treatment of a laterally spreading tumor of the rectum, and the wound was closed by an endoscopist using a purse-string suture. Unfortunately, the patient then presented with delayed rectal perforation (6 h after ESD). The surgeons at the local hospital attempted to treat the perforation and wound surface using transrectal endoscopic microsurgery (TEM); however, the perforation worsened and became enlarged, multiple injuries to the mucosa around the perforation and partial tearing of the rectal mucosa occurred, and the internal anal sphincter was damaged. As a result, the perforation became more complicated. Due to the increased bleeding, surgical treatment with suturing could not be performed using TEM. Therefore, the patient was sent to our medical center for follow-up treatment. After a multidisciplinary discussion, we believed that the patient should undergo an enterostomy. However, the patient strongly refused this treatment plan. Because the position of the rectal perforation was relatively low and the intestine had been adequately prepared, we attempted to treat the complicated delayed rectal perforation using a self-expanding covered mental stent (SECMS) in combination with a transanal ileus drainage tube (TIDT). CONCLUSION For patients with complicated delayed perforation in the lower rectum and adequate intestinal preparation, a SECMS combined with a TIDT can be used and may result in very good outcomes.

Abstract
BACKGROUND Lymph node skip metastases are common in lung, breast, and thyroid cancer patients, but are rare in colon cancer patients. Specifically, lymph node skip metastases occur in 1%-3% of colon cancer patients. Previous reports have demonstrated colon cancer skip metastases involving the retropancreatic and portocaval lymph nodes and Virchow's node; however, reports involving skip metastases into the left neck lymph nodes and left shoulder skin are extremely rare, as are related reports of clinical treatment and prognosis.
CASE SUMMARY A 44-year-old Chinese man was admitted to the hospital for evaluation of persistent shoulder pain for 3 d and a cutaneous mass (3.0 cm × 2.0 cm) on the left shoulder. The left shoulder cutaneous mass was excised and bisected, revealing tissues with a fish-like appearance. The pathologic diagnosis of the cutaneous mass suggested a signature [CDX-2 (++), CK20 (++), Ki-67 (+) > 50%] of infiltrating or metastatic colorectal adenocarcinoma. An enhanced computed tomography scan of the abdomen revealed chronic appendicitis with fecal stone formation, cecal edema, and a pelvic effusion. A colonoscopy revealed a cauliflower-like mass within the ascending colon area that involved the lumen. The surface of the ascending colon mass was eroded and bleeding; a biopsy was performed. The pathologic diagnosis of the colonoscopy biopsy was an ascending colon mucinous adenocarcinoma. The patient underwent a laparoscopic radical resection of the right colon based on the pathological diagnosis. The tumor was 5.0 cm × 4.5 cm × 1.8 cm in size and infiltrated the entire thickness of the intestinal wall with vascular tumor thrombi. No nerve tissue involvement was noted. The ileum and colon resection margins were negative. The postoperative pathologic analysis revealed non-metastatic involvement of ileocecal, pericolic, or peri-ileal lymph nodes. The postoperative medical examination revealed palpably enlarged lymph nodes in the left neck, and the following color Doppler ultrasound examination of the neck confirmed enlarged lymph nodes in the left neck. After surgical resection and pathologic diagnosis, a common pathologic signature consistent with resected cutaneous mass and right colon was identified, suggesting skip metastasis of left cervical lymph nodes. The patient was then treated with eight courses of chemotherapy and under follow-up evaluations for 4 years; currently, no tumor recurrences or metastases have been noted.
CONCLUSION We report an abnormal skip metastasis involving the left shoulder skin and left neck lymph node in a patient with ascending colon adenocarcinoma. Specifically, we observed non-metastatic involvement of the lymph nodes around the tumor site but with metastases to the cervical lymph nodes. The standard surgical operations were performed to resect the cutaneous mass, tumor tissue, and cervical lymph nodes, followed by chemotherapy for eight courses. The patient is healthy with no tumor recurrences or metastases for 4 years. This clinical case will contribute to future research about the abnormal skip metastasis in colon cancers and a better clinical treatment design.

Abstract
BACKGROUND Femoral and tibial stress injuries are commonly found in long distance running athletes. Stress fractures have rarely been reported in athletes performing high intensity interval training (HIIT) exercise. The objective of this study was to report a case of a patient who presented with medial tibial stress syndrome and femoral neck stress fracture after performing HIIT exercises. CASE SUMMARY A 26 year old female presented with bilateral medial tibial pain. She had been performing HIIT exercise for 45 min, five times weekly, for a seven month period. Her tibial pain was gradual in onset, and was now severe and worse on exercise, despite six weeks of rest. Magnetic resonance imaging (MRI) revealed bilateral medial tibial stress syndrome. As she was taking norethisterone for birth control, a dual energy X-ray absorbitometry scan was performed which demonstrated normal bone mineral density of her lumbar spine and femoral neck. She was managed conservatively with analgesia and physiotherapy, but continued to exercise against medical advice. She presented again six months later with severe right hip pain. MRI of her right hip demonstrated an incomplete stress fracture of her subtrochanteric region. Her symptoms resolved with strict rest and physiotherapy. CONCLUSION HIIT may cause stress injury of the tibia and femur in young individuals.

Abstract
BACKGROUND Acute-on-chronic liver failure (ACLF) is the abrupt exacerbation of declined hepatic function in patients with chronic liver disease. AIM To explore the independent predictors of short-term prognosis in patients with hepatitis B virus (HBV)-related ACLF and to establish a predictive short-term prognosis model for HBV-related ACLF. METHODS From January 2016 to December 2019, 207 patients with HBV-related ACLF attending the 910th Hospital of Chinese People's Liberation Army were continuously included in this retrospective study. Patients were stratified based on their survival status 3 mo after diagnosis. Information was collected regarding gender and age; coagulation function in terms of prothrombin time and international normalized ratio (INR); hematological profile in terms of neutrophil-to-lymphocyte ratio (NLR) and platelet count (PLT); blood biochemistry in terms of alanine aminotransferase, aspartate aminotransferase, total bilirubin (Tbil), albumin, cholinesterase, blood urea nitrogen (BUN), creatinine, blood glucose, and sodium (Na); tumor markers including alpha-fetoprotein (AFP) and Golgi protein 73 (GP73); virological indicators including HBV-DNA, HBsAg, HBeAg, Anti-HBe, and Anti-HBc; and complications including hepatic encephalopathy, hepatorenal syndrome, spontaneous peritonitis, gastrointestinal bleeding, and pulmonary infection. RESULTS There were 157 and 50 patients in the survival and death categories, respectively. Univariate analysis revealed significant differences in age, PLT, Tbil, BUN, NLR, HBsAg, AFP, GP73, INR, stage of liver failure, classification of liver failure, and incidence of complications (pulmonary infection, hepatic encephalopathy, spontaneous bacterial peritonitis, and upper gastrointestinal bleeding) between the two groups (P < 0.05). GP73 [hazard ratio (HR): 1.009, 95% confidence interval (CI): 1.005-1.013, P = 0.000], middle stage of liver failure (HR: 5.056, 95%CI: 1.792-14.269, P = 0.002), late stage of liver failure (HR: 22.335, 95%CI: 8.544-58.388, P = 0.000), pulmonary infection (HR: 2.056, 95%CI: 1.145-3.690, P = 0.016), hepatorenal syndrome (HR: 6.847, 95%CI: 1.930-24.291, P = 0.003), and HBsAg (HR: 0.690, 95%CI: 0.524-0.908, P = 0.008) were independent risk factors for short-term prognosis in patients with HBV-related ACLF. Following binary logistics regression analysis, we arrived at the following formula for predicting short-term prognosis: Logit(P) = Ln(P/1-P) = 0.013 × (GP73 ng/mL) + 1.907 × (middle stage of liver failure) + 4.146 × (late stage of liver failure) + 0.734 × (pulmonary infection) + 22.320 × (hepatorenal syndrome) - 0.529 × (HBsAg) - 5.224. The predictive efficacy of the GP73-ACLF score was significantly better than that of the Model for End-Stage Liver Disease (MELD) and MELD-Na score models (P < 0.05). CONCLUSION The stage of liver failure, presence of GP73, pulmonary infection, hepatorenal syndrome, and HBsAg are independent predictors of short-term prognosis in patients with HBV-related ACLF, and the GP73-ACLF model has good predictive value among these patients.

Abstract
BACKGROUND Intestinal seromuscular bladder augmentation (SMBA) surgery has produced no mucosal-related complications, but its outcomes need to be studied. AIM To evaluate the safety and effectiveness of SMBA in the treatment of children with neurogenic bladder. METHODS A retrospective analysis of the clinical data of children with SMBA was performed from March 2008 to February 2018, and the data were compared with those of children receiving standard cystoplasty (SC). RESULTS In a cohort of 67 children who underwent bladder augmentation, the 46 children in the SC group had an average age of 10.6 years and a follow-up time of 36 mo, and the 21 children in the SMBA group had an average age of 7.6 years and a follow-up time of 29.7 mo. The preoperative and postoperative bladder volumes in the SMBA group were 151.7 mL and 200.4 mL, respectively, and those in the SC group were 173.9 mL and 387.0 mL, respectively. No significant difference in preoperative urinary dynamic parameters was found between the two groups, but the difference after operation was statistically significant. The main complications after SMBA were residual ureteral reflux and failed bladder augmentation, with incidences of 33.3% and 28.6%, respectively. In all 6 patients with failed augmentation in the SMBA group, ileum seromuscular patches were used for augmentation, and SC was chosen for reaugmentation. During reoperation, patch contracture and fibrosis were observed. CONCLUSION The improvement of urinary dynamic parameters in the SMBA group was significantly lower than that in the SC group. Children with SMBA had a higher probability of patch contracture and reaugmentation, which might be related to impaired blood supply and urine stimulation, and the sigmoid colon patch should be the priority.

Abstract
BACKGROUND Skin bronchogenic cysts are extremely rare congenital bronchocystic changes caused by the abnormal development of the trachea, bronchial trees or lung buds during the embryonic period. The first case of skin bronchogenic cysts was reported in 1945. Since then, this disease has attracted increasing attention, but due to the low incidence, its pathogenesis is still not clear.
CASE SUMMARY Here, we report another case of skin bronchogenic cysts with infection in a 64-year-old female patient. The patient had no symptoms for more than 60 years until her chest wall was recently found to be swollen, and she felt pain and discomfort. At the same time, secretions were found on the surface of the swelling. Color Doppler ultrasound examination showed abnormal echoes in the soft tissue under the frontal chest wall, suggesting the presence of cysts. Cytological puncture resulted in about 2 mL of pus and showed the presence of more acute inflammatory cells. The final clinical diagnosis was skin cyst with infection, and surgery was carried out. The pathological results obtained after surgery showed that the cystic wall was covered with column-like cilia epithelial cells, and the interstitial structure was partially inundated with inflammatory cells. After a variety of examinations and clinical diagnoses, we finally confirmed that the patient was suffering from bronchogenic cyst.
CONCLUSION This article not only describes the case of an elderly patient with rare skin bronchogenic cysts with infection but also provides a detailed and correct diagnosis and a successful treatment process, which is of great value for the diagnosis and treatment of the disease.

Abstract
Gastrointestinal (GI) involvement has been reported in approximately 50% of patients with coronavirus disease 2019 (COVID-19), which is due to the pathogenic role of inflammation and the intestinal function of the angiotensin-converting enzyme 2 and its receptor. Accumulating adult data has pointed out that gut dysbiosis might occur in these patients with a potential impact on the severity of the disease, however the role of gut microbiota in susceptibility and severity of COVID-19 disease in children is still poorly known. During the last decades, the crosstalk between gut and lung has been largely recognized resulting in the concept of “gut-lung axis” as a central player in modulating the development of several diseases. Both organs are involved in the common mucosal immune system (including bronchus-associated and gut-associated lymphoid tissues) and their homeostasis is crucial for human health. In this framework, it has been found that the role of GI dysbiosis is affecting the homeostasis of the gut-liver axis. Of note, a gut microbiome imbalance has been linked to COVID-19 severity in adult subjects, but it remains to be clarified. Based on the increased risk of inflammatory diseases in children with COVID-19, the potential correlation between gut microbiota dysfunction and COVID-19 needs to be studied in this population. We aimed to summarize the most recent evidence on this striking aspect of COVID-19 in childhood.

Abstract
BACKGROUND Spontaneous pneumoperitoneum (SP) without gastrointestinal perforation rarely occurs in neonates, with most SP cases being idiopathic. Although SP usually follows a benign clinical course with favorable prognosis, it can become life-threatening in certain situations. In these cases, urgent surgical intervention may be required. Therefore, it may be difficult to decide when or how to perform prompt interventions. AIM To demonstrate the distinct clinical features of SP to guide appropriate management by comparing characteristics between SP and typical pneumoperitoneum secondary to gastrointestinal perforation. METHODS We retrospectively reviewed electronic medical records and identified 37 neonates with radiological evidence of pneumoperitoneum who were treated at our institution. Clinical variables were compared between neonates with SP without gastrointestinal perforation (Group A) and those with pneumoperitoneum secondary to gastrointestinal perforation (Group B). Clinical variables between groups were compared using Student’s t-test and the chi-square test. The risk factors related to mortality were examined using multi-logistic regression analysis. RESULTS Group A comprised 35.1% (13/37) of the patients. The frequency of persistent pulmonary hypertension (53.8%) and pneumothorax (46.2%) before the development of pneumoperitoneum was significantly higher in group A than in group B (P = 0.004). Platelet count and partial pressure of arterial oxygen (PaO2) were significantly lower in group A (P = 0.015 and 0.025, respectively). Overall mortality was significantly higher in group A than in group B (76.9% vs 16.7%, P = 0.001). Only preterm infants were significantly associated with high mortality (P = 0.041; odds ratio = 18.0). Accompaniment with persistent pulmonary hypertension and pneumothorax were also significantly high (P = 0.004) in group A, but these were not strongly associated with high mortality. CONCLUSION This study identified a higher mortality rate in patients with SP than that described in previous reports. Neonates with SP were more likely to have thrombocytopenia, pneumothorax, and persistent pulmonary hypertension. Prematurity was the most significant factor affecting mortality.

Abstract
BACKGROUND Mechanical ventilation is a common resuscitation method in the intensive care unit (ICU). Unfortunately, this treatment process prolongs the ICU stay of patients with an increased incidence of delirium, which ultimately affects the prognosis.
AIM To evaluate the effect of progressive early rehabilitation training on treatment and prognosis of patients with mechanical ventilation in ICU.
METHODS The convenience sampling method selected 190 patients with mechanical ventilation admitted to the Fourth Hospital of Hebei Medical University from March 2020 to March 2021. According to the random number table method, they were divided into the control and intervention groups. The control group received routine nursing and rehabilitation measures, whereas the intervention group received progressive early rehabilitation training. In addition, the incidence and duration of delirium were compared for the two groups along with mechanical ventilation time, ICU hospitalization time, functional independence measure (FIM) score, Barthel index, and the incidence of complications (deep venous thrombosis, pressure sores, and acquired muscle weakness).
RESULTS In the intervention group, the incidence of delirium was significantly lower than in the control group (28% vs 52%, P < 0.001). In the intervention group, the duration of delirium, mechanical ventilation time, and ICU stay were shorter than in the control group (P < 0.001). The FIM and Barthel index scores were significantly higher in the intervention group than the control group (P < 0.001). The total incidence of complications in the intervention group was 3.15%, which was lower than 17.89% in the control group (P < 0.001).
CONCLUSION Progressive early rehabilitation training reduced the incidence of delirium and complications in ICU patients with mechanical ventilation, which improved prognosis and quality of life.

Abstract
BACKGROUND Autoimmune pancreatitis (AIP) is a particular type of chronic pancreatitis, and steroid treatment of AIP is effective. Spontaneous remission (SR) of AIP without steroids is relatively rare. The international consensus for the treatment of autoimmune pancreatitis suggests that patients with AIP with obstructive jaundice, abdominal pain, and back pain related to the pancreas or the bile duct should be treated with steroids; most asymptomatic patients with AIP may improve without steroids. However, in our clinical work, we found that the clinical characteristics of AIP patients with SR vary. Four of these cases are described here. In addition, to our knowledge, there is no previously published report of dynamic imaging before and after SR of AIP at present. CASE SUMMARY We present the cases of four patients with AIP (two females and two males) in which the AIP improved spontaneously without steroid treatment. Two patients were asymptomatic, one patient had abdominal pain with obstructive jaundice, and one patient had intermittent right upper abdominal pain. Three patients presented with localized pancreatic enlargement and one with diffuse pancreatic enlargement. In addition to the pancreatic lesions, bile duct involvement was seen in two patients, and no extra-pancreatic organ involvement was found in the other two patients. The serum IgG4 level of all patients was more than twice the normal level. After SR in the four patients, the affected pancreases exhibited three types of image features: Return to normal, progressive fibrosis, and atrophy and calcification. CONCLUSION The clinical features of SR in our four patients with AIP differ, but the imaging findings share some characteristics. After SR, in some cases the affected pancreas could return to normal, although some patients suffer from progressive fibrosis and atrophy as well as calcification.

Abstract
BACKGROUND Delayed inflammatory reactions (DIRs) in alloplast rhinoplasty are a rare complication that may occur several months to years after surgery. The exact causes and mechanisms are unclear, but several triggering factors, including infections, trauma, dental procedures, and vaccination, have been reported. CASE SUMMARY A 39-year-old male patient who had undergone augmentation rhinoplasty 8 years ago had DIRs after the administration of the first dose of the mRNA Pfizer coronavirus disease 2019 (COVID-19) vaccine. He suddenly had tender, erythematous swelling on his face 6 d after vaccination. As there was no improvement in the patient’s condition after the conservative treatment, surgical removal of an alloplastic nasal implant was performed. Immediately after the surgery, the DIRs and accompanying symptoms ameliorated rapidly. A histological study conducted during surgery was fibrosis and small fragments of the hyaline cartilage. CONCLUSION The correlation between DIRs and COVID-19 vaccination has not been reported yet and the exact mechanism is unclear. Because the uncontrolled inflammatory reactions on the nose leave serious sequelae, surgeons should be conscious of the correlation between COVID-19 vaccines and DIRs associated with nasal alloplastic implants. And further histological or microbiological studies should be performed to determine the cause of DIRs.

Abstract
BACKGROUND Bladder malacoplakia is a rare chronic granulomatous disease. The most common site of the malacoplakia is the urinary system. The etiology of bladder malacoplakia is complex, with its clinical misdiagnosis rate is high. Therefore, exposure to more clinical cases is necessary to improve the diagnosis and treatment of this condition.
CASE SUMMARY A 65-year-old woman was admitted to our hospital because of dysuria. She presented with dysuria, frequent urination, urgency, pain, and absence of hematuria and pyuria. After the examination, bladder tumor electrocision was performed under combined intravenous and inhalation anesthesia on September 6, 2021. During the operation, electrotomy and electrocoagulation were performed. The operation was then followed by anti-infection treatment, and the patient recovered well. The postoperative pathology was diagnosed as bladder malacoplakia by light and electron microscopic analyses. On a follow-up after 4 mo, no significant difference between electrotomy and electrocoagulation was found, with both achieving a curative effect.
CONCLUSION Diagnosing bladder malacoplakia depends on histopathological examination. Antibiotic treatment with bladder tumor resection or electrocoagulation provides better therapeutic effect.

Abstract
BACKGROUND Ataxia with vitamin E deficiency (AVED) is a type of autosomal recessive cerebellar ataxia. Clinical manifestations include progressive cerebellar ataxia and movement disorders. TTPA gene mutations cause the disease.
CASE SUMMARY We report the case of a 32-year-old woman who presented with progressive cerebellar ataxia, dysarthria, dystonic tremors and a remarkably decreased serum vitamin E concentration. Brain magnetic resonance images showed that her brainstem and cerebellum were within normal limits. Acquired causes of ataxia were excluded. Whole exome sequencing subsequently identified a novel homozygous variant (c.473T>C, p.F158S) of the TPPA gene. Bioinformatic analysis predicted that F185S is harmful to protein function. After supplementing the patient with vitamin E 400 mg three times per day for 2 years, her symptoms remained stable.
CONCLUSION We identified an AVED patient caused by novel mutation in TTPA gene. Our findings widen the known TTPA gene mutation spectrum.

Abstract
BACKGROUND The coexistence with patent ductus arteriosus (PDA), mitral valve prolapse (MVP), atrial fibrillation (AF) and hyperthyroidism is extremely rare and complex. The optimal therapeutic strategy is difficult to develop. CASE SUMMARY A 27-year-old female with PDA, MVP, AF and hyperthyroidism presented with severe dyspnea. Given that a one-stage operation for PDA, MVP and AF is high risk, we preferred a sequential multidisciplinary minimally invasive therapeutic strategy. First, PDA transcatheter closure was performed. Hyperthyroidism and heart failure were simultaneously controlled via medical treatment. Video-assisted thoracoscopic mitral valve repair and left atrial appendage occlusion were performed when heart failure was controlled. Under this therapeutic strategy, the patient’s sinus rhythm was restored and maintained. Two years after the treatment, the symptoms of heart failure were relieved, and the enlarged heart was reversed. CONCLUSION Sequential multidisciplinary therapeutic strategies, which take advantage of both internal medicine and surgical approaches, might be reasonable for this type of disease.

Abstract
BACKGROUND Epiglottic cysts is a rare but potentially lethal supraglottic airway pathology in infants due to the high risk of cannot intubation or cannot ventilation. Awake fiberoptic intubation appeared to be the safest technique, but it is very challenging in infants with large epiglottic cysts. Even it has the risk of airway loss. We report that cyst aspiration is an effective treatment as the first-choice procedure for airway management in an infant with large epiglottic cysts. CASE SUMMARY A 46-day-old male infant weighing 2.3 kg presented to the emergency room with difficulty feeding, worsening stridor, and progressive respiratory distress. Epiglottic cysts was diagnosed, but fibro bronchoscopy examination failed, as the fiberoptic bronchoscope was unable to cross the epiglottic cysts to the trachea. The infant was transferred to the operating room for emergency cystectomy under general anesthesia. Spontaneous respiration was maintained during anesthesia induction, and cyst aspiration was performed as the first procedure for airway management under video laryngoscopy considering that the preoperative fibro bronchoscopy examination failed. Then, the endotracheal tube was intubated successfully. Cystectomy was performed uneventfully, and the infant was safely transferred to the intensive care unit after surgery. The infant was extubated smoothly on the third postoperative day and discharged on the eighth day after surgery. On follow-up 1 year after the surgery, a normal airway was found by fibro bronchoscopy examination. CONCLUSION Epiglottic cyst aspiration can be considered the first procedure for airway management in infants with large epiglottic cysts.

Abstract
BACKGROUND Gouty tophi are a chronic granulomatous caused by a deposition of monosodium urate crystal deposition in the body. Once broken, it may easily induce severe infection. Sepsis complicated with secondary hemophagocytic syndrome induced by gouty tophi rupture is extremely rare in the clinical setting, and no such serious complications have been reported in literature. CASE SUMMARY This is a 52-year-old Chinese male patient with a 20-year history of gouty arthritis. At admission, the gout stone in the patient’s right ankle was broken and it secreted a white mucoid substance. During the course of treatment, the patient suffered from systemic inflammatory response syndrome multiple times. His condition gradually deteriorated, further complicated by hemophagocytic syndrome. After thorough removal of gout lesions and active anti-infection treatment and control of blood uric acid level, combined with multidisciplinary cooperation, the patient was finally cured. CONCLUSION Sepsis complicated with secondary hemophagocytic syndrome induced by gouty tophi rupture is extremely rare in the clinical setting. Timely and accurate diagnosis is very important to save patients' lives.

Abstract
BACKGROUND Diabetic nephropathy (DN) is a common complication of type 1 and type 2 diabetes that can lead to kidney damage and high blood pressure. Increasing evidence support the important roles of microproteins and cytokines, such as β2-microglobulin (β2-MG), glycosylated hemoglobin (HbA1c), and vascular endothelial growth factor (VEGF), in the pathogenesis of this disease. In this study, we identified novel therapeutic options for this disease.
AIM To analyze the guiding significance of β2-MG, HbA1c, and VEGF levels in patients with DN.
METHODS A total of 107 patients with type 2 diabetes mellitus complicated with nephropathy and treated in our hospital from May 2018 to February 2021 were included in the study. Additionally, 107 healthy individuals and 107 patients with simple diabetes mellitus were selected as the control groups. Changes in β2-MG, HbA1c, and VEGF levels in the three groups as well as the different proteinuria exhibited by the three groups were examined.
RESULTS Changes in β2-MG, HbA1c, and VEGF levels in the disease, healthy, and simple diabetes groups were significantly different (P < 0.05). The expression of these factors from high to low were evaluated in different groups by pairwise comparison. In the disease group, high to low changes in β2-MG, HbA1c, and VEGF levels were noted in the massive proteinuria, microproteinuria, and normal urinary protein groups, respectively. Changes in these factors were positively correlated with disease progression.
CONCLUSION The expression of serum β2-MG, HbA1c, and VEGF was closely correlated with DN progression, and disease progression could be evaluated by these factors.

Abstract
BACKGROUND Gallbladder neuroendocrine carcinoma (GB-NEC) has a low incidence rate; therefore, its clinical characteristics, diagnosis, treatment and prognosis are not well explored. AIM To review recent research and analyze corresponding data in the Surveillance Epidemiology and End Results (SEER) database. METHODS Data of GB-NEC (n = 287) and gallbladder adenocarcinoma (GB-ADC) (n = 19 484) patients from 1975 to 2016 were extracted from the SEER database. Survival analysis was performed using Kaplan–Meier and Cox proportional hazards regression. P < 0.05 was considered statistically significant. We also reviewed 108 studies retrieved from PubMed and Reference Citation Analysis (https://www.referencecitationanalysis.com/). The keywords used for the search were: "(Carcinoma, Neuroendocrine) AND (Gallbladder Neoplasms)". RESULTS The GB-NEC incidence rate was 1.6% (of all gallbladder carcinomas), male to female ratio was 1:2 and the median survival time was 7 mo. The 1-, 2-, 3- and 5-year overall survival (OS) was 36.6%, 17.8%, 13.2% and 7.3% respectively. Serum chromogranin A levels may be a specific tumor marker for the diagnosis of GB-NEC. Elevated carcinoembryonic antigen, carbohydrate antigen (CA)-19-9 and CA-125 levels were associated with poor prognosis. Age [hazard ratio (HR) = 1.027, 95% confidence interval (CI): 1.006–1.047, P = 0.01] and liver metastasis (HR = 3.055, 95% CI: 1.839–5.075, P < 0.001) are independent prognostic risk factors for OS. Patients with advanced GB-NEC treated with surgical resection combined with radiotherapy and/or chemotherapy may have a better prognosis than those treated with surgical resection alone. There was no significant difference in OS between GB-NEC and GB-ADC. CONCLUSION The clinical manifestations and prognosis of GB-NEC are similar to GB-ADC, but the treatment is completely different. Early diagnosis and treatment are the top priorities.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) has been far more devastating than expected, showing no signs of slowing down at present. Heilongjiang Province is the most northeastern province of China, and has cold weather for nearly half a year and an annual temperature difference of more than 60ºC, which increases the underlying morbidity associated with pulmonary diseases, and thus leads to lung dysfunction. The demographic features and laboratory parameters of COVID-19 deceased patients in Heilongjiang Province, China with such climatic characteristics are still not clearly illustrated. AIM To illustrate the demographic features and laboratory parameters of COVID-19 deceased patients in Heilongjiang Province by comparing with those of surviving severe and critically ill cases. METHODS COVID-19 deceased patients from different hospitals in Heilongjiang Province were included in this retrospective study and compared their characteristics with those of surviving severe and critically ill cases in the COVID-19 treatment center of the First Affiliated Hospital of Harbin Medical University. The surviving patients were divided into severe group and critically ill group according to the Diagnosis and Treatment of New Coronavirus Pneumonia (the seventh edition). Demographic data were collected and recorded upon admission. Laboratory parameters were obtained from the medical records, and then compared among the groups. RESULTS Twelve COVID-19 deceased patients, 27 severe cases and 26 critically ill cases were enrolled in this retrospective study. No differences in age, gender, and number of comorbidities between groups were found. Neutrophil percentage (NEUT%), platelet (PLT), C-reactive protein (CRP), creatine kinase isoenzyme (CK-MB), serum troponin I (TNI) and brain natriuretic peptides (BNP) showed significant differences among the groups (P = 0.020, P = 0.001, P < 0.001, P = 0.001, P < 0.001, P < 0.001, respectively). The increase of CRP, D-dimer and NEUT% levels, as well as the decrease of lymphocyte count (LYMPH) and PLT counts, showed significant correlation with death of COVID-19 patients (P = 0.023, P = 0.008, P = 0.045, P = 0.020, P = 0.015, respectively). CONCLUSION Compared with surviving severe and critically ill cases, no special demographic features of COVID-19 deceased patients were observed, while some laboratory parameters including NEUT%, PLT, CRP, CK-MB, TNI and BNP showed significant differences. COVID-19 deceased patients had higher CRP, D-dimer and NEUT% levels and lower LYMPH and PLT counts.

Abstract
BACKGROUND Incontinentia pigmenti (IP) is a rare X-linked dominant genetic disorder that can be fatal in male infants. It is a disease that affects many systems of the human body. In addition to characteristic skin changes, patients may also have pathological features of the eyes, teeth, and central nervous system. Therefore, the lesions in these systems may be the first symptoms for which patients seek treatment. To date, no cases of IP complicated by intracranial arachnoid cyst (IAC) have been reported. This paper aims to report a case of IP with IAC in order to share the diagnosis and treatment experience of this rare case with other clinicians.
CASE SUMMARY An 11-year-old female patient suffered intermittent limb convulsions for five months and was sent to hospital. In the initial stage, the patient was considered to have primary epilepsy. Further investigation of the patient's medical history, physical examination and imaging examination led to the diagnosis of IP combined with intracranial space-occupying lesions, and secondary epilepsy. The patient was treated with craniotomy, and postoperative pathology revealed an IAC. The patient recovered well after craniotomy and had no obvious surgery-related complications. During the follow-up period, the patient did not have recurrent epilepsy symptoms.
CONCLUSION IP is a multi-system disease that presents with typical skin lesions at birth, but the long-term prognosis of this disease depends on the involvement of systems other than the skin, especially nervous system and ocular lesions.

Abstract
BACKGROUND Malignant pleural mesothelioma has limited therapeutic options and a poor outcome. Antiangiogenic agents might increase the efficacy of immunotherapy as second-line treatment of advanced-stage malignancies. CASE SUMMARY A patient with stage IIIB pleural mesothelioma received second-line treatment with a combination of pembrolizumab, bevacizumab and chemotherapy following standard chemotherapy under the guidance of second-generation sequencing. He achieved a partial response after four cycles of treatment with progression-free survival of 5 mo. Pembrolizumab was suspended due to grade 2 immunerelated pneumonia, which was resolved by oral glucocorticoids. However, disease progression was observed after immunotherapy rechallenge and anlotinib therapy. The patient had disease progression, multiorgan dysfuntion and died suddenly in October 2019. CONCLUSION The combination of immune checkpoint inhibitor, anti-angiogenic agents and chemotherapy showed effective response for advanced pleural mesothelioma, but with adverse reactions.

Abstract
BACKGROUND Low-grade endometrial stromal sarcoma (LGESS) classically exhibits a proliferative morphology. However, morphological variation of extrauterine tumors presents a diagnostic challenge. CASE SUMMARY We report the case of a 76-year-old female patient with extensive extrauterine and abdominal neoplastic lesions. Computed tomography showed massive pleural and ascitic fluid, and there was an increase in serum cancer antigen 125. She underwent bilateral adnexectomy and tumor resection. The right ovary had been replaced by a multinodular mass that was 8.5 cm × 4.5 cm × 3.5 cm in size. In addition, there was a 24 cm × 15 cm × 13 cm mesenteric mass, which was also multinodular, with local invasion of the intestinal serosa and underlying muscle. Under the microscope, the tumors in different places exhibited two different patterns, thus presenting great challenges to diagnosis and treatment. Thorough pathological assessment eliminated all differential diagnoses in favor of metastatic LGESS derived from a 20-year-old primary tumor initially misdiagnosed as leiomyosarcoma. CONCLUSION LGESS morphology varies according to tumor location. Accurate diagnosis is critical for appropriate treatment and improved prognosis and patient care.

Abstract
BACKGROUND Total knee arthroplasty (TKA) has been shown to improve quality of life and reduce pain. High-flexion activities such as squatting, kneeling, and floor transfers are mainly listed as demanding tasks. Among them, squatting is an important position. AIM To provide a new squat position classification and evaluate the different squatting positions of a series of patients after primary TKA. METHODS From May 2018 to October 2019, we retrospectively reviewed 154 video recordings of the squatting-related motions of patients after TKA. Among the included patients, 119 were women and 35 were men. Their mean age at the index surgery was 61.4 years (range, 30 to 77). RESULTS The median follow-up was 12 mo (range, 6 to 156 mo). We classified those squatting-related motions into three major variations according to squatting depth: Half squat, parallel squat, and deep squat. The angles of hip flexion, knee flexion, and ankle dorsiflexion were measured in the screenshots captured from the videos at the moment of squatting nadir. A total of 26 patients were classified as half squats, 75 as parallel squats, and 53 as deep squats. The angles of hip flexion, knee flexion, and ankle dorsiflexion all differed significantly among the three squatting positions (P < 0.001). In the parallel squat group, the mean knee flexion angle (°) was 116.5 (SD, 8.1; range, 97 to 137). In the deep squat group, the mean knee flexion angle (°) was 132.5 (SD, 9.3; range, 116 to 158). CONCLUSION Among the three squatting positions, deep squat showed the highest hip, knee, and ankle flexion angles, followed by the parallel squat. With the improvement of squatting ability, the patient's postoperative satisfaction rate was also significantly enhanced. However, the different squatting abilities of the patients cannot be effectively distinguished from the scoring results (P > 0.05). Our squatting position classification offers a pragmatic approach to evaluating patients’ squatting ability after TKA.

Abstract
With the advance of invasive interventions, the treatment model for infected necrotizing pancreatitis (INP) has shifted from open surgery to the step-up minimally invasive treatment. Late intervention, originating from the open surgery era, has been questioned in the minimally invasive period. With the emergence of new high-quality evidence about the timing for intervention, it seems to be increasingly apparent that, even in the age of minimal invasiveness, “late intervention” waiting for the necrotic collections to be encapsulated is still necessary. This opinion review mainly discusses the intervention timing for INP.

Abstract
Rhythm control is the core part of the integrated management of atrial fibrillation (AF), especially in the early stages. Despite advances in catheter ablation (CA), the recurrence rate of AF after CA remains high. As a result, stratification and early management of AF recurrence after CA are critical. Currently, predictors of recurrence of AF after CA are mostly based on dysfunction caused by structural remodeling, apart from traditional risk factors. Atrial strain is a recently developed important parameter for detecting the deformability of atrial myocardium during the cardiac cycle prior to atrial remodeling. Although there is only preliminary evidence, atrial strain is still a promising parameter in predicting the recurrence of AF after CA at an early stage. This review focuses on the evaluation of atrial strain, the current applications of atrial strain in assessing atrial function, and predicting the recurrence of AF after CA. We summarize the contents related as follows: (1) CA for rhythm control in AF; (2) Evaluation methods of atrial strain; (3) Atrial strain in the remodeling and reverse remodeling of AF; and (4) Clinical applications of atrial strain in predicting the recurrence of AF after CA. Although there is accumulating evidence on the role of decreased atrial strain in the early prediction of AF recurrence, atrial strain is limited in clinical practice for lacking exact cut-off values and difficulty in distinguishing specific function phases of the atrium. More research is needed in the future to add strength to the early prediction value of atrial strain in AF recurrences.

Abstract
We recently read with interest the original research article entitled "Disease exacerbation is common in inflammatory bowel disease patients treated with immune checkpoint inhibitors for malignancy". The abovementioned article is an observational retrospective cohort study, which could be of particular value for clinicians to understand how immunotherapy affects pre-existing enteral disease in inflammatory bowel disease patients. Although we appreciate the endeavor of Samuel Rubin et al, based on our in-depth analysis, we detected a potential shortcoming in this article; thus, we present our comments in this letter. If the authors contemplate these comments on their relevant research, we believe that their contribution would be considerable for future studies.

Abstract
BACKGROUND Duplication of the renal pelvis is a common congenital malformation of the urinary system. About one-third of cases are complete unilateral duplication of the renal pelvis, while bilateral duplication is extremely rare. Herein, we described a single case of bilateral renal duplication with double ureteral orifice ectopic vaginal fistula treated with laparoscopy.
CASE SUMMARY A 6-year-old girl suffering from long-term vaginal leakage was admitted on June 10, 2018. She was diagnosed with complete duplication of both kidneys and ureters and ectopic opening of both ureters combined with ureterovaginal fistula. The patient received laparoscopic ectopic ureteral bladder replantation and was followed up for 2 years. No renal function damage and vaginal leakage were found.
CONCLUSION Laparoscopic bladder-ureter reimplantation could effectively determine the location and number of ectopic ureters by imaging and cystoscopy.

Abstract
BACKGROUND Papillary thyroid cancer (PTC) is the most common malignant tumor of the thyroid. However, the coexistence of PTC and sarcoma in one patient is rare. In this article, we report the case of a patient who presented with both PTC and undifferentiated pleomorphic sarcoma (UPS), which has not been previously reported in the online Medline database (PubMed). CASE SUMMARY A 71-year-old man was admitted to our hospital for a mass on the right side of his neck for one month, which rapidly enlarged within 2 wk with distending pain. The patient was diagnosed with a thyroid malignancy by fine-needle aspiration and underwent total thyroidectomy and bilateral central lymph node dissection. Histology and immunohistochemistry revealed features of both PTC and UPS. The thyroid cancer 8 gene detection kit results showed BRAF and telomerase reverse transcriptase mutations. The disease progressed rapidly, and the patient died four months after surgery from extensive lung metastasis. CONCLUSION Our report highlights the patient’s pathological characteristics and related genetic mutations. Due to the rapid development and poor prognosis of cooccurring PTC and sarcoma, it is important for clinical physicians and pathologists to raise awareness of this type of tumor.

Abstract
BACKGROUND Phosphoglyceride crystal deposition disease (PCDD) is a rare acquired disease in which phospholipid crystals deposit in bone and soft tissue long after surgery, trauma, or repeated injections.
CASE SUMMARY A 60-year-old-woman was referred to our department because of multiple abdominal masses after open splenectomy for idiopathic thrombocytopenic purpura 29 years earlier. All the masses showed marked fluorodeoxyglucose (FDG) uptake on 18F-fluorodeoxyglucose positron emission tomography (18F-FDG-PET) and were strongly suspected to be malignant tumors. Surgical biopsies were performed, and the abdominal masses were found to be aligned vertically, three in a row, along the tissue layers cut in the patient’s previous surgery. Pathological finding of the specimens showed foreign body granuloma consisting of histiocytes and multinucleated giant cells accumulating around needle-like crystals. The crystals were confirmed as phosphoglyceride by Raman spectroscopy, and PCDD was diagnosed. To our knowledge, this is the first report of PCDD diagnosed by Raman spectroscopy.
CONCLUSION We made a definitive diagnosis of PCDD in a patient with multiple tumors showing marked FDG uptake on 18F-FDG-PET by incisional biopsy and compo- sition analysis using Raman spectroscopy, a method that has not previously been reported for the diagnosis of PCDD.

Abstract
BACKGROUND Liver abscess is a common clinical liver disease mainly caused by suppurative bacteria or amoebae, with early clinical signs of chills, high fever, jaundice, and other symptoms. Establishing its early diagnosis is difficult, which may lead to misdiagnosis. AIM To observe the effects of psychological guidance combined with evidence-based health intervention in patients with liver abscess treated with ultrasound. METHODS A total of 120 patients with bacterial liver abscess admitted to our hospital from May 2018 to February 2021 were selected and divided into groups according to their intervention plan. RESULTS After the intervention, Self-Rating Depression Scale, Self-Rating Anxiety Scale, Self-Perceived Burden Scale (SPBS), and quality of life scores (physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional, mental health) were lower than before the intervention in the two groups. The observation group had lower negative sentiment, SPBS, and quality of life scores than the control group. In the observation group, 31 and 24 patients had good and general compliance, respectively, with a compliance rate of 91.67%, which was significantly higher than that in the control group. The observation group had significantly lower total incidence of incision infection, abdominal abscess, hemorrhage, and severe abdominal pain than the control group. CONCLUSION Three-dimensional psychological guidance combined with evidence-based health intervention in treating liver abscess can reduce patients’ burden and negative emotions, improve patient compliance and quality of life, and reduce complications.

Abstract
BACKGROUND Alzheimer’s disease (AD) influences the social and economic quality of life of older adult patients and their families.
AIM To explore the efficacy of cognitive training in clinical nursing for patients with early AD residing in the plateau area.
METHODS This pilot study was conducted in patients with early AD treated in the Geriatric Department of the Qinghai Provincial People’s Hospital between August 2019 and March 2021. The patients were divided into a cognitive training group and a conventional nursing group using the random number table method. Patients in the conventional nursing group received conventional nursing, whereas the patients in the cognitive training group received the new nursing intervention. The mini-mental state examination (MMSE) and activities of daily living (ADL) scales were used to compare the cognitive ability and daily activities, respectively, between the two groups before and after the intervention.
RESULTS Sixty patients were enrolled in this study, with 30 patients in the cognitive training group and conventional nursing group, respectively. The MMSE and ADL scores were significantly higher in the cognitive training group than in the conventional nursing group after the intervention (MMSE: 25.11 ± 2.02 vs 22.26 ± 1. 23, P = 0.032; ADL: 68.72 ± 4.86 vs 60.16 ± 2.27, P = 0.018).
CONCLUSION The application of cognitive training in clinical nursing for patients with early AD could improve both their cognitive ability and ADL. This method could be applied in clinical practice to manage cognitive dysfunction in patients with early AD.

Abstract
BACKGROUND A biliary inflammatory myofibroblastic tumor (IMT) is a rare type of mesenchymoma that, although it has a broad age spectrum, usually occurs in adults. Diagnosis is difficult because biliary IMTs often exhibit nonspecific clinical symptoms and imaging features, resulting in delayed or inappropriate treatment. Although most IMTs are benign, some show malignant properties such as infiltration, recurrence, and metastasis. CASE SUMMARY Here, we retrospectively describe a 10-month-old infant who was admitted to our hospital due to stubborn jaundice. The patient responded poorly to routine medical treatment and his clinical manifestations and laboratory tests lacked specificity, so we turned to repeated ultrasound scans and other imaging examinations. As both hepatosplenic ultrasonography and diffusion-weighted magnetic resonance imaging demonstrated a space-occupying lesion, an exploratory laparotomy was performed. The final diagnosis made over two mo after the disease onset was infant biliary cirrhosis caused by a biliary IMT, which partially infiltrated into the liver. This infant is the youngest case of biliary IMTs that has been reported till now. The patient underwent an incomplete resection of the mass and Kasai Portoenterostomy. However, because of cirrhosis, he also received a paternal liver transplant. Since some IMTs show malignant properties, we proceeded with a three-year of follow-up; however, no recurrence or metastasis has been noted. CONCLUSION Neoplastic disease such as IMTs should be considered when routine medical treatment of obstructive jaundice is not successful. Observation of dynamic imaging changes is helpful for diagnosis. Periodic follow-up is necessary for IMTs.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) is a global pandemic putting the population at a high risk of infection-related health hazards, mortality and a potential failure of proper medical therapies. Therefore, it is necessary to evaluate the potential use of the existing drugs that could be used as options for the medical management of COVID-19 patients.
AIM To evaluate the role of the H2 receptor blocker “famotidine” in COVID-19 illness.
METHODS This study was done on seriously ill COVID-19 patients admitted to the intensive care unit (ICU) from different institutes in Bangladesh. Patients were divided into famotidine treatment group “A” (famotidine 40 mg to 60 mg oral formulation every 8 h with other treatment as given), and control group “B” (treatment as given). National early warning score (NEWS)-2, and sequential organ failure assessment day-1 score was calculated to evaluate the outcome. Outcomes were evaluated by the time required for clinical improvement, characterized as duration required from enrollment to the achievement of NEWS-2 of ≤ 2 maintained for 24 h; time to symptomatic recovery, defined as the duration in days (from randomization) required for the recovery of the COVID-19 symptoms; mortality rate; duration of ICU and hospital stay; total period of hospitalization; the rate of supplementary oxygen requirement; the computed tomography (CT) chest recovery (%), the time required for the viral clearance and “NEWS-2” on discharge.
RESULTS A total of 208 patients were enrolled in this study with 104 patients in each group. The famotidine treatment group had comparatively better recovery of 75% and a low mortality of 25% than the control with a recovery of 70% and a mortality of 30%. Duration of clinical improvement (group A 9.53 d, group B 14.21 d); hospitalization period among the recovered patients (group A 13.04 d, group B 16.31 d), pulmonary improvement in chest CT (group A 21.7%, group B 13.2%), and the time for viral clearance (group A 20.7 d, group B 23.8 d) were found to be statistically significant P ≤ 0.05. However, the Kaplan Meier survival test was not significant among the two study groups, P = 0.989.
CONCLUSION According to our study, treatment with famotidine achieved a better clinical outcome compared to the control group in severe COVID-19 illness, although no significant survival benefit was found.

Abstract
BACKGROUND Myeloid sarcoma (MS), including isolated and leukaemic MS, is an extramedullary myeloid tumour. MS can involve any anatomical site, but MS of the female genital tract is rare, with the ovaries and uterine body and cervix being the most commonly seen sites. Involvement of the vagina and vulva is extremely rare. CASE SUMMARY We report a rare case of MS with involvement of the vulva and vagina and massive infiltration of the pelvic floor. A 26-year-old woman presented with a vulvar mass, irregular vaginal bleeding and night sweats. Magnetic resonance imaging demonstrated an ill-defined, irregular vulvovaginal mass with massive involvement of the paravaginal tissue, urethra, posterior wall of the bladder, and pelvic floor. The signal and enhancement of the huge mass was homogeneous without haemorrhage or necrosis. Positron emission tomography/computed tomography showed high fluorodeoxyglucose uptake by the mass. Peripheral blood count detected blast cells. Vulvovaginal mass and bone marrow biopsies were performed, and immunohistochemistry confirmed the diagnosis of acute myeloid leukaemia (M-2 type, FAB classification) and vulvovaginal MS. The patient was treated with induction chemotherapy followed by allogeneic haematopoietic stem cell transplantation, and achieved complete remission. A systemic review of the literature on vulvovaginal MS was conducted to explore this rare entity’s clinical and radiological features. CONCLUSION Vulvovaginal MS is extremely rare. Diagnosis of vulvovaginal MS can only be confirmed histopathologically. Even though its clinical and imaging presentations are nonspecific, MS should be considered in the differential diagnosis of a newly developed T2-hyperintense, homogeneously enhanced vulvovaginal mass, especially in a patient with suspected haematological malignancy.

Abstract
BACKGROUND Hepatitis-associated aplastic anemia (HAAA) is a rare condition. Patients with HAAA usually present with acute hepatitis, jaundice and significantly increased transaminase. After 1–2 mo, hepatitis gradually improves, but progressive hemocytopenia, bone marrow hematopoietic failure, and severe or extremely severe aplastic anemia are manifest. Most cases of HAAA are fulminant and usually lethal if left untreated. The literature on Epstein–Barr virus (EBV)-associated HAAA is sparse. CASE SUMMARY We report a 30-year-old man who was admitted to our hospital because of pale yellow urine and skin with a simultaneous decrease in peripheral blood ternary cells. We made a diagnosis of EBV-associated HAAA. The treatment strategy for this patient included eltrombopag, an immunosuppressive regimen of rabbit anti-human thymocyte immunoglobulin, cyclosporine, and supportive care. The patient was discharged in normal physical condition after five months. A hemogram performed on follow-up revealed that he had achieved a complete response. CONCLUSION Eltrombopag plus anti-thymocyte globubin and cyclosporine may be a therapeutic option for EBV-associated HAAA.Larger studies are warranted to confirm.

Abstract
BACKGROUND When interpreting nuclear medicine images, unexpected findings are sometimes encountered. Recognizing these findings and determining the mechanism of their occurrence could have a significant impact on early diagnosis of critical diseases and the appropriate management of patients. CASE SUMMARY A 59-year-old man was admitted to the emergency room due to left hemiparesis, left hemifacial palsy, and mild dysarthria. After 2 wk of hospitalization, the patient complained of dry eyes and mouth. Thus, salivary scintigraphy was performed to evaluate the functional status of his salivary glands. Incidental accumulation in the right frontoparietal area was found on salivary scintigraphy. Fluid-attenuated inversion recovery phase magnetic resonance (FLAIR phase MR) image showed diffuse high signal intensity in the same area. Anterior and posterior horns of the right lateral ventricle were obliterated and the midline was slightly shifted to the left side due to right frontoparietal swelling. On salivary scintigraphy, Tc-99m pertechnetate was incidentally accumulated in a subacute cerebral infarction lesion. Two years after the diagnosis of acute infarction, the second series of salivary scintigraphy showed no abnormal activity in the brain. FLAIR phase MR image also demonstrated markedly decreased high signal intensity in the previous infarction lesion without evidence of swelling indicating chronic cerebral infarction. CONCLUSION This case highlights that Tc-99m pertechnetate could accumulate in a subacute cerebral infarction lesion. The mechanism of an unexpected uptake of Tc-99m pertechnetate in unusual sites should be evaluated and kept in mind for better interpretation.

Abstract
BACKGROUND Relapsing polychondritis is a rare multisystem autoimmune disease that mainly involves systemic cartilage and proteoglycan-rich tissues. If the larynx and trachea are involved, the patient’s condition deteriorates rapidly. When relapsing polychondritis becomes more advanced, the airways collapse and treatment is difficult, rendering a poor prognosis. Therefore, the diagnosis method, treatment strategy and prognosis of relapsing polychondritis with larynx and trachea involvement need to be elucidated to improve clinicians’ awareness of the disease. CASE SUMMARY A man and a woman were admitted because of breathlessness. Relapsing polychondritis was diagnosed after a series of accessory examinations. They were both treated with glucocorticoids and immunosuppressants, and underwent tracheotomy as their breathing difficulties could not be relieved by the medication. CONCLUSION The two cases highlight the importance of the timely diagnosis, full evaluation and initiating individualized treatment of relapsing polychondritis with larynx and trachea involvement. Laryngoscopy, bronchoscopy and pathological examination are helpful in diagnosis of this disease.

Abstract
BACKGROUND Hepatic encephalopathy (HE) is a neurocognitive condition in cirrhosis leading to frequent hospitalizations. Nonselective beta-blockers (NSBBs) are the mainstay of pharmacologic treatment in cirrhotic patients. We hypothesized that since NSBBs decrease cardiac output and portal flow, the decreased metabolic filtering process of liver parenchyma may lead to increased HE-related hospitalizations. AIM To evaluate the impact of NSBB administration on HE-related readmissions in cirrhotic patients. METHODS In this retrospective cohort study, we included 393 patients admitted to Baylor University Medical Center for liver-related portal hypertension indications between January 2013 and July 2018. Independent predictors of the first HE-related readmissions were identified using Cox proportional hazards analysis. The cumulative incidence of the first HE-related readmissions between patients receiving NSBBs and not receiving NSBBs was examined using Fine-Gray modeling to account for the competing risk of death or liver transplantation. RESULTS The mean age was 58.1 ± 10.2 years and most patients fell into Child class C (49.1%) or B (43.8%). The median Model for End-Stage Liver Disease-Sodium score was 22 (IQR: 11). The cumulative incidence of the first HE-related readmissions was significantly higher in patients taking NSBBs compared to patients not receiving NSBBs (71.8% vs 41.8%, P < 0.0001). In multivariate analysis, after adjusting for demographics, markers of liver disease severity, selective beta-blocker, lactulose and rifaximin use, NSBB use [Hazard ratio: 1.74 (95%CI: 1.29-2.34)] was independently associated with the first HE-related readmissions over a median follow-up of 3.8 years. CONCLUSION NSBB use is independently associated with increased HE-related readmissions in patients with cirrhosis, regardless of liver disease severity.

Abstract
BACKGROUND Sarcoidosis is a multisystem disorder with unknown etiology, and it predominantly affects the lungs and intrathoracic lymph nodes. For patients with atypical clinical manifestations, the diagnosis of sarcoidosis is difficult and specific biomarkers may play an important role in assisting diagnosis. Previous research has demonstrated a correlation between sarcoidosis and increased carbohydrate antigen 125 (CA125), but remains a lack of large cohort studies to validate this observation. AIM To compare serum CA125 levels in sarcoidosis patients and healthy controls, and explore whether CA125 can be used as a biomarker for the diagnosis of sarcoidosis. METHODS In this study, the serum CA125 levels were measured by enzyme-linked immunosorbent assay in 108 consecutive sarcoidosis patients between June 2016 and December 2020 (31 males, 77 females; age at diagnosis 49.69 ± 9.10 years) and 112 healthy subjects. Data on the C-reactive protein, erythrocyte sedimentation rate, and angiotensin-converting enzyme were also collected. The association of serum CA125 levels with clinical, radiological, and respiratory functional characteristics was analyzed between patient groups with CA125 ≤ 35 U/mL or CA125 > 35 U/mL. RESULTS We found that serum CA125 levels were higher in sarcoidosis patients compared to healthy controls (median: 44.78 vs 19.11 U/mL, P < 0.001). The area under the receiver operator characteristic was 0.9833 (95%CI: 0.9717-0.9949), and the best cutoff point was 32.33 U/mL. The elevated serum CA125 was notably associated with the percentage of predicted forced vital capacity (FVC%) and neutrophil-to-lymphocyte ratio (P = 0.043 and P = 0.038, respectively) in sarcoidosis patients. Multivariate analysis revealed that FVC% was a statistically notable predictor of elevated serum CA125 (P = 0.029). Also, our research revealed that compared to patients with Stage I of radiology classification, patients with Stage II and III showed a higher concentration of serum CA125 (46.16 ± 8.32 vs 41.00 ± 6.04 U/mL, P = 0.005, and 47.92 ± 10.10 vs 41.00 ± 6.04 U/mL, P = 0.002, respectively). CONCLUSION Serum CA125 was highly increased in sarcoidosis patients and showed high efficiency for noninvasive diagnosis of the disease. In addition, abnormally elevated serum CA125 was correlated with pulmonary function and radiological Scadding’s classification of sarcoidosis.

Abstract
BACKGROUND Tracheal tumors may cause airway obstruction and pose a significant risk to ventilation and oxygenation. Due to its rarity, there is currently no established protocol or guideline for anesthetic management of resection of upper tracheal tumors, therefore individualized strategies are necessary. There are limited number of reports regarding the anesthesthetic management of upper tracheal resection and reconstruction (TRR) in the literature. We successfully used intravenous ketamine to manage a patient with a near-occlusion upper tracheal tumor undergoing TRR. CASE SUMMARY A 25-year-old female reported progressive dyspnea and hemoptysis. Bronchoscopy showed an intratracheal tumor located one tracheal ring below the glottis, which occluded > 90% of the tracheal lumen. The patient was scheduled for TRR. Considering the risk of complete airway collapse after the induction of general anesthesia, we decided to secure the airway with a tracheostomy with spontaneous breathing. The surgeons needed to transect the trachea 1-2 cartilage rings below and above the tumor borders: a time-consuming process. Coughing and movement needed be minimized; thus, we added intravenous ketamine to local anesthetic infiltration. After tracheostomy, an endotracheal tube was placed into the distal trachea, and general anesthesia was induced. The surgeons resected four cartilage rings with the tumor attached and anastomosed the posterior tracheal wall. We performed a video-laryngoscopy to place a new endotracheal tube. Finally, the surgeons anastomosed the anterior tracheal walls. The patient was extubated uneventfully. CONCLUSION Ketamine showed great advantages in the anesthesia of upper TRR by providing analgesia with minimal respiratory depression or airway collapse.

Abstract
BACKGROUND Fused teeth usually involve several complications, such as the development of caries in the groove between fused crowns, tooth impaction, diastemas, aesthetic and periodontal problems, and pulpal pathosis, due to the complex anatomical structure of fused teeth. A thorough diagnosis is paramount to forming an accurate treatment plan and obtaining a favourable prognosis. With the advent of cone-beam computed tomography (CBCT), accurate 3-dimensional images of teeth and their surrounding dentoalveolar structures can now be readily obtained, and the technology can accurately provide a minimally invasive approach to acquire detailed diagnostic information. Therefore, we utilize CBCT data herein to generate a digital model for the infected region in a patient, and this model enables us to better plan the management of his case.
CASE SUMMARY This report details the diagnosis and endodontic treatment of a rare case involving a fused maxillary second molar and two paramolars with apical periodontitis. The patient experienced pain upon biting and cold sensitivity in the area of the maxillary left molar. No caries or other defects were identified in these teeth, and a normal response to a pulp electric viability test was observed. With the aid of CBCT and digital model technology, we initially suspected that the infection originated from the isthmus between the maxillary second molar and two paramolars. Therefore, we only treated the isthmus by an endodontic approach and did not destroy the original tooth structure; furthermore, the vital pulp was retained, and good treatment outcomes were observed at the 24-month follow-up.
CONCLUSION This finding may provide new insights and perspectives on the diagnosis and treatment of fused teeth.

Abstract
BACKGROUND Periosteal chondroma is a very rare benign tumor that develops adjacent to the cortical surface of bone and beneath the periosteal membrane. Periosteal chondroma of the rib is an extremely rare entity. CASE SUMMARY The patient was a 43-year-old man who had been incidentally found to have a mediastinal mass 1 mo earlier. Plain computed tomography showed a lobulated soft tissue mass on the right side of the T4/5 vertebra that measured about 47 mm × 28 mm in the transverse view and contained diffuse stippled calcification. The mass caused cortical scalloping of the right fourth rib and marginal bone sclerosis. Enhanced computed tomography showed mild enhancement of the mass. Magnetic resonance imaging showed a lobulated mass on the right side of the thoracic vertebra with long TI and T2 signals, mottling, and patchy long T1 and short T2 signals inside. The lesion had a hypointense rim. Enhanced magnetic resonance imaging showed enhancement predominantly at the periphery of the tumor. The tumor was approached through a right posterolateral thoracotomy, and parts of the fourth and fifth ribs were excised with the tumor. Postoperative pathological analysis revealed periosteal chondroma of the rib. CONCLUSION Periosteal chondroma of the rib has a low incidence and typical imaging manifestations. Understanding its imaging features is helpful to ensure a correct preoperative diagnosis.

Abstract
BACKGROUND A low survival rate in patients with cardiac arrest is associated with failure to recognize the condition in its initial stage. Therefore, recognizing the warning symptoms of cardiac arrest in the early stage may play an important role in survival. AIM To investigate the warning symptoms of cardiac arrest and to determine the correlation between the symptoms and outcomes. METHODS We included all adult patients with all-cause cardiac arrest who visited Peking University Third Hospital or Beijing Friendship Hospital between January 2012 and December 2014. Data on population, symptoms, resuscitation parameters, and outcomes were analysed. RESULTS Of the 1021 patients in the study, 65.9% had symptoms that presented before cardiac arrest, 25.2% achieved restoration of spontaneous circulation (ROSC), and 7.2% survived to discharge. The patients with symptoms had higher rates of an initial shockable rhythm (12.2% vs 7.5%, P = 0.020), ROSC (29.1% vs 17.5%, P = 0.001) and survival (9.2% vs 2.6%, P = 0.001) than patients without symptoms. Compared with the out-of-hospital cardiac arrest (OHCA) without symptoms subgroup, the OHCA with symptoms subgroup had a higher rate of calls before arrest (81.6% vs 0.0%, P < 0.001), health care provider-witnessed arrest (13.0% vs 1.4%, P = 0.001) and bystander cardiopulmonary resuscitation (15.5% vs 4.9%, P = 0.002); a shorter no flow time (11.7% vs 2.8%, P = 0.002); and a higher ROSC rate (23.8% vs 13.2%, P = 0.011). Compared to the in-hospital cardiac arrest (IHCA) without symptoms subgroup, the IHCA with symptoms subgroup had a higher mean age (66.2 ± 15.2 vs 62.5 ± 16.3 years, P = 0.005), ROSC (32.0% vs 20.6%, P = 0.003), and survival rates (10.6% vs 2.5%, P < 0.001). The top five warning symptoms were dyspnea (48.7%), chest pain (18.3%), unconsciousness (15.2%), paralysis (4.3%), and vomiting (4.0%). Chest pain (20.9% vs 12.7%, P = 0.011), cardiac etiology (44.3% vs 1.5%, P < 0.001) and survival (33.9% vs 16.7%, P = 0.001) were more common in males, whereas dyspnea (54.9% vs 45.9%, P = 0.029) and a non-cardiac etiology (53.3% vs 41.7%, P = 0.003) were more common in females. CONCLUSION Most patients had warning symptoms before cardiac arrest. Dyspnea, chest pain, and unconsciousness were the most common symptoms. Immediately recognizing these symptoms and activating the emergency medical system prevents resuscitation delay and improves the survival rate of OHCA patients in China.

Abstract
BACKGROUND The factors influencing the prognosis of patients with esophageal cancer vary among studies and are still poorly known.
AIM To determine the factors associated with survival in patients with esophageal cancer.
METHODS This retrospective study included patients with esophageal cancer admitted between January 2017 and March 2020 at Heping Hospital Affiliated to Changzhi Medical College. All patients were treated according to the available guidelines. Follow-up was censored in October 2020. Univariable and multivariable Cox regression analyses were used to determine the independent risk factors for overall survival (OS).
RESULTS In total, 307 patients were included. Their median age was 64 (range, 44-79) years, 63.5% were male, and the median disease course was 2 (0.1-36) months. The median tumor size was 3 (0-10) cm. Most patients were T3 (29.6%), N0 (70.0%). Most tumors were grade 2 (48.2%), and 87.3% were squamous cell carcinoma. The in-hospital mortality was 16.9%, the 30-day mortality was 19.9%, and the 90-day mortality was 25.4%. The cumulative OS rates at the last follow-up were 82.1% (95%CI: 67.7%-96.5%) for stage 0/I/II and 47.4% (95%CI: 16.5-78.6%) for stage III/IVA (P < 0.001). The multivariable analysis showed that creatinine levels (HR = 1.02, 95%CI: 1.00-1.03, P = 0.050), pTNM III/IVA (HR = 4.19, 95%CI: 2.19-8.01, P < 0.001), adjuvant radiotherapy and/or chemotherapy (HR = 0.23, 95%CI: 0.11-0.49), and the Comprehensive Complication Index (CCI) (HR = 1.02, 95%CI: 1.004-1.03, P = 0.011) were independently associated with OS.
CONCLUSION The survival of patients with esophageal cancer is poor, especially those with pTNM III/IVA. pTNM stage III/IVA, CCI, and adjuvant therapy (radiotherapy and/or chemotherapy) are independently associated with OS.

Abstract
BACKGROUND The diagnostic value of metagenomic next-generation sequencing (mNGS) in central nervous system (CNS) infectious diseases after empirical treatment has not been reported.
AIM To investigate the diagnostic value of mNGS of cerebrospinal fluid (CSF) in the empirically treated CNS infectious diseases.
METHODS A total of 262 CSF samples from patients with suspected CNS infections were collected between August 2020 and December 2021. Both mNGS and conventional methods were used for testing. The conventional methods included microbial culture, smear, polymerase chain reaction, etc.
RESULTS Among 262 suspected cases, 183 cases (69.84%) were diagnosed as CNS infection, including 86 cases of virus infection (47.00%), 70 cases of bacterial infection (38.25%) and 27 cases of fungal infection (14.76%). The sensitivity and specificity of mNGS were 65.6% (95%CI: 58.2%-72.3%) and 89.6% (95%CI: 79.1%-95.3%), respectively. The PPV of mNGS was 94.5% (95%CI: 88.6%-97.6%), and the NPV was 48.8% (95%CI: 39.7%–57.9%). The pathogen detective sensitivity and accuracy of mNGS were higher than those of conventional methods (Sensitivity: 65.6% vs 37.2%; P < 0.001; Accuracy: 72.0% vs 50%, P < 0.001). The results showed that compared with conventional methods, mNGS technology was a more sensitive method for the diagnosis of CNS infection after empirical treatment.
CONCLUSION mNGS can be a better method applied in the diagnosis of CNS infection after empirical treatment.

Abstract
BACKGROUND Primary spinal cord (PSC) glioblastoma (GB) is an extremely rare but fatal primary tumor of the central nervous system and associated with a poor prognosis. While typical tumor imaging features are generally easy to recognize, glioblastoma multiforme can have a wide range of imaging findings. Atypical GB is often misdiagnosed, which usually delays the optimal time for treatment. In this article, we discuss a clinical case of pathologically confirmed PSC GB under the guise of benign tumor imaging findings, as well as the most recent literature pertaining to PSC GB. CASE SUMMARY A 70-year-old female complained of limb weakness lasting more than 20 d. Irregular masses were observed inside and outside the left foramina of the spinal canal at C7-T1 on medical imaging. Based on the imaging features, radiologists diagnosed the patient with schwannoma. Tumor resection was performed under general anesthesia. The final histopathological findings revealed a final diagnosis of PSC GB, world health organization Grade IV. The patient subsequently underwent a 4-wk course of radiotherapy (60 Gy in 20 fractions) combined with temozolomide chemotherapy. The patient was alive at the time of submission of this manuscript. CONCLUSION Atypical GB presented unusual imaging findings, which led to misdiagnosis. Therefore, a complete recognition of imaging signs may facilitate early accurate diagnosis.
