ABSTRACT
Mesh-related visceral complications caused by mesh erosion after tension-free inguinal hernia repair are one kind of rare long-term complications, but they are easily neglected. Interval time from initial hernia repair to mesh-related visceral complications by preperitoneal and laparoscopic repair is short. Rutkow and transabdominal preperitoneal repair have the highest reported rate. Lichtenstein has the longest interval time and the lowest reported rate. The most frequently eroded organs are sigmoid colon, bladder and small intestine. The common clinical manifestations of sigmoid colon erosion are hematochezia, abdominal wall fistula and colitis, hematuria and recurrent urinary tract infection in bladder erosion cases, intestinal obstruction and abdominal wall fistula in intestinal erosion case, sigmoid-bladder fistula and intestinal-bladder fistula in multiple organ erosion cases. Resection or repair of corresponding organs with mesh removal have good efficacies in most patients. The authors summarize and analyze researches on mesh-related visceral complications after tension-free inguinal hernia repair from 1994 to 2021, review their advances, in order to raise awareness of such complications in clinicians.
ABSTRACT
Pulmonary arterial hypertension (PAH) is a devastating pulmonary circulation disease lacking high-efficiency therapeutics. The present study aims to decipher the therapeutic mechanism of Rhodiola crenulata, a well-known traditional chinese medicine with cardiopulmonary protection capacity, on PAH by exploiting functional lipidomics. The rat model with PAH was successfully established for first, following Rhodiola crenulata water extract (RCE) treatment, then analysis of chemical constituents of RCE was performed, additional morphologic, hemodynamic, echocardiographic measurements were examined, further targeted lipidomics assay was performed to identify differential lipidomes, at last accordingly mechanism assay was done by combining qRT-PCR, Western blot and ELISA. Differential lipidomes were identified and characterized to differentiate the rats with PAH from healthy controls, mostly assigned to acylcarnitines, phosphatidylcholines, sphingomyelin associated with the PAH development. Excitingly, RCE administration reversed high level of decadienyl-L-carnitine by the modulation of metabolic enzyme CPT1A in mRNA and protein level in serum and lung in the rats with PAH. Furthermore, RCE was observed to reduce autophagy, confirmed by significantly inhibited PPARγ, LC3B, ATG7 and upregulated p62, and inactivated LKB1-AMPK signal pathway. Notably, we accurately identified the constituents in RCE, and delineated the therapeutic mechansim that RCE ameliorated PAH through inhibition of fatty acid oxidation and autophagy. Altogether, RCE might be a potential therapeutic medicine with multi-targets characteristics to prevent the progression of PAH. This novel findings pave a critical foundation for the use of RCE in the treatment of PAH.
ABSTRACT
OBJECTIVE: To investigate the clinical characteristics and treatment experience of mullerian adenosarcoma ofuterine.METHODS:A retrospective analysis was conducted on the clinical data of 19 women with Mullerianadenosarcoma of uterus between January 2005 and December 2015.RESULTS:The patients were 28 to 70 years old,withan average of 51.9 years old.9 were premenopause and 10 were postmenopause.The main clinical features are abnormalvaginal bleeding and cervical neoplasms.Preoperative b-ultrasound examination showed abnormal findings in 11 patientsand MRI examination in 8 patients.Sixteen patients received preoperative pathological examination(diagnosticcurretage or cervical biopsy),and the diagnosis accuracy reached 87.5%.Seventeen patients received surgical treatmentand 7 patients received postoperative chemotherapy.The patients were followed up until June 2018,for 11 to 148 months,and 7 died,of which one died from complicated renal failure and 6 died in 5 years after surgery.4 were lost to follow-up,and 8 survived.CONCLUSION:Clinical symptoms of Mullerian adenosarcoma of the uterus are not typical,and abnormalvaginal bleeding is often the first symptom.Endometrial curettage or cervical biopsy can improve the clinical diagnosisrate,and surgery and chemotherapy are the main treatment.
