Currently, there are limited studies on C-SCLC, and there is no uniform standard treatment, especially for extensive C-SCLC, which still faces great challenges. In recent years, the development and progress of immunotherapy have provided more possibilities for the treatment of C-SCLC. We used immunotherapy combined with first-line chemotherapy to treat extensive-stage C-SCLC to explore its antitumor activity and safety.CASE SUMMARY We report a case of C-SCLC that presented early with adrenal, rib, and mediastinal lymph node metastases. The patient received carboplatin and etoposide with concurrent initiation of envafolimab. After 6 cycles of chemotherapy, the lung lesion was significantly reduced, and the comprehensive efficacy evaluation showed a partial response. No serious drug-related adverse events occurred during the treatment, and the drug regimen was well tolerated.CONCLUSION Envafolimab combined with carboplatin and etoposide in the treatment of extensive-stage C-SCLC has preliminary antitumor activity and good safety and tolerability.展开更多

The vortex-induced vibration equation of a casing pipe was set up considering the beam mode and Morison’s nonlinear fluid loads as well as the vortex-excited loads. The approach of calculating vortex-excited nonlinear vibration by Galerkin’s method was proposed. The natural vibration frequencies and modes were obtained, and the response including primary resonance induced by current and the composite resonance under combined wave-current for the 170 m long casing pipe in the 160m depth of water were investigated.

文摘BACKGROUND Pancreatic ductal adenocarcinoma(PDAC)is a highly fatal disease with limited effective treatment especially after first-line chemotherapy.The human epidermal growth factor receptor 2(HER-2)immunohistochemistry(IHC)positive is associated with more aggressive clinical behavior and shorter overall survival in PDAC.CASE SUMMARY We present a case of multiple metastatic PDAC with IHC mismatch repair proficient but HER-2 IHC weakly positive at diagnosis that didn’t have tumor regression after first-line nab-paclitaxel plus gemcitabine and PD-1 inhibitor treatment.A novel combination therapy PRaG 3.0 of RC48(HER2-antibody-drug conjugate),radio-therapy,PD-1 inhibitor,granulocyte-macrophage colony-stimulating factor and interleukin-2 was then applied as second-line therapy and the patient had confirmed good partial response with progress-free-survival of 6.5 months and overall survival of 14.2 month.She had not developed any grade 2 or above treatment-related adverse events at any point.Percentage of peripheral CD8^(+) Temra and CD4^(+) Temra were increased during first two activation cycles of PRaG 3.0 treatment containing radiotherapy but deceased to the baseline during the maintenance cycles containing no radiotherapy.CONCLUSION PRaG 3.0 might be a novel strategy for HER2-positive metastatic PDAC patients who failed from previous first-line approach and even PD-1 immunotherapy but needs more data in prospective trials.
文摘BACKGROUND Primary ciliary dyskinesia(PCD)is an inherited autosomal-recessive disorder of impaired mucociliary clearance characterized by chronic respiratory diseases,otolaryngological diseases,central nervous system abnormalities,reproductive system abnormalities,and cardiac function abnormalities.General anesthesia in these patients is associated with a higher incidence of respiratory complications than in patients without the disease.CASE SUMMARY A 16-year-old male patient was referred to the emergency room complaining of right ankle pain due to distal tibiofibular fracture.Three years prior,he had been diagnosed with PCD.At that time,he had experienced several episodes of pneumonia,sinusitis,and chronic middle ear infections,for which he underwent surgical interventions.At the current admission,he presented with cough and sputum but no other respiratory symptoms.A chest computed tomography scan revealed centrilobular ground-glass opacities in both lower lobes and a calcified nodule in the left lower lobe.For the surgical procedure and postoperative pain management,combined spinal-epidural anesthesia was employed.The patient’s postoperative pain score was measured by the numerical rating scale(NRS).On the day of surgery,his NRS was 5 points.By the second postoperative day,the NRS score had decreased to 2–3 points.The epidural catheter was removed on the fourth day following the operation.The patient was subsequently discharged no respiratory complications.CONCLUSION We performed combined spinal-epidural anesthesia in a patient with PCD.The patient experienced no additional respiratory complications and was discharged with a low NRS score for pain.

文摘BACKGROUND Paragangliomas(PGLs)are rare catecholamine-secreting neuroendocrine tumors,which often present with secondary hypertension.The most common location is the retroperitoneal space.For the first time,we report a rare case of large retroperitoneal compound PGL,and we have innovatively applied a new surgical plan to completely remove the tumor.CASE SUMMARY A 55-year-old middle-aged man was admitted to the hospital for fluctuating blood pressure for more than 1 year with intermittent headache.He suffered dozens of attacks every day.Blood and urine catecholamines were elevated,somatostatin receptor imaging was positive,and the diagnosis of PGL was clear.The imaging examination revealed a large tumor on the right front of the mediastinal spine at the level of T10-L1(the posterior space of the right phrenic foot).For the first time in our department,a combined thoracoscopic and laparoscopic operation was used to detect and remove large tumors.CONCLUSION This is the first reported case of using a thoracoscopic and laparoscopic approach simultaneously to remove a large retroperitoneal compound PGL,which may provide a new surgical approach for similar cases.
文摘BACKGROUND Combined pituitary hormone deficiency 3(CPHD3;OMIM:221750)is caused by mutations within the LHX3 gene(OMIM:600577),which located on the subtelomeric region of chromosome 9 at band 9q34.3,has seven coding exons and six introns.LIM homeobox(LHX)3 protein is the key regulator of pituitary development in fetal life.CASE SUMMARY We have diagnosed and treate an 11-year-old boy with combined pituitary hormone deficiency(CPHD).The main clinical manifestations were pituitary hormone deficiency,hydrocele of the tunica vaginalis,pituitary dwarfism,gonadal dysplasia,micropenis,clonic convulsion,and mild facial dysmorphic features.We collected peripheral blood from the patient,the patient's older brother,as well as their parents,and sequenced them by using high-throughput whole-exosome sequencing,which was verified by Sanger sequencing.The results showed that there were two compound heterozygous variants of c.613G>C(p.V205L)and c.220T>C(p.C74R)in the LHX3 gene.c.613G>C(p.V205L)was inherited from his mother and c.220T>C(p.C74R)from his father.His brother also has both variants and symptoms.CONCLUSION This study reported ununreported genetic mutations of LHX3,and recorded the treatment process of the patients,providing data for the diagnosis and treatment of CPHD.
