To date, no genetic changes other than missense variants were reported in the literature. Here, we report a five-month old female infant with typical ILLD(failure to thrive, developmental delay, jaundice, diffuse interstitial lung disease, hepatomegaly with severe steatosis, anemia, and thrombocytosis) showing novel phenotypes such as kidney stones, acetabular dysplasia, prolonged fever, and extreme leukocytosis. Whole exome sequencing revealed a novel truncating variant(c.2158 C>T/p.Gln720 Stop) together with a novel tri-nucleotide insertion(c.893_894 insTCG that caused the insertion of an arginine at amino acid position 299) in the MARS gene.展开更多

METHODS： Liver transplantation models were estab- lished using male Wistar rats. Donor livers were pre- served in University of Wisconsin solution at 4 ℃ for different lengths of time. The effect of ammonium pyr- rolidinedithiocarbamate （PDTC） on ALI was also detect- ed. All samples were harvested after 3 h reperfusion.The severity of AU was evaluated by lung weight/body weight ratio, lung histopathological score, serum nitric oxide （NO） and endothelin （ET）-I levels, lung tumor necrosis factor （TNF）-α and interleukin （IL）-1β levels. Lung surfactants （LSs） were determined by micellar electrokinetic capillary chromatography. RESULTS： With extended donor liver cold preservation time （CPT）, lung histopathological scores, serum ET-i levels, lung weight/body weight ratio and the level of TNF-α and IL-1β in lung were increased significantly in the 180-min group compared with the sham group （3.16± 0.28 vs 1.12 ± 0.21, P 〈 0.001; 343.59±53.97 vs 141.53± 48.48, P 〈 0.001; 0.00687 ±0.00037 vs 0.00557 ±0.00056, P 〈 0.001; 17.5 ± 3.0 vs 1,3 ± 0.3, P 〈 0.001; 10.8± 2.3 vs 1.8 ± 0.4, P 〈 0.001）, but serum NO levels decreased remarkably （74.67 ± 10.01 vs 24.97 ± 3.18, P 〈 0.001）. The expression of lung phos- phatidylcholine （PC）, phosphatidylethanolamine （PE）, phosphatidylinositol （PI） and phosphatidylserine （PS） increased when CPT was 〈 120 rain, and decreased when CPT was 〉 180 min （PC： 1318.89 ± 54.79 vs 1011.18± 59.99, P 〈 0.001; PE： 1504.45± 119.96 vs 1340.80±76.39, P = 0.0019; PI： 201.23 ± 34.82 vs 185.88 ± 17.04, P = 0.2265; PS： 300.43±32.95 vs 286.55± 55.55, P = 0.5054）.

Herein, we report a case of fatal crizotinib-induced liver failure in a 37-year-old Asian patient.CASE SUMMARY The patient complained of dyspnea and upper abdominal pain for a week in August 2017. He was diagnosed with anaplastic lymphoma kinase-rearranged lung adenocarcinoma combined with multiple distant metastases. Crizotinib was initiated as a first-line treatment at a dosage of 250 mg twice daily. No adverse effects were seen until day 46. On day 55, he was admitted to the hospital with elevated liver enzymes aspartate aminotransferase(AST)(402 IU/L), alanine aminotransferase(ALT)(215 IU/L) and total bilirubin(145 μmol/L) and was diagnosed with crizotinib-induced fulminant liver failure. Despite crizotinib discontinuation and intensive supportive therapy, the level of AST(1075 IU/L),ALT(240 IU/L) and total bilirubin(233 μmol/L) continued to rapidly increase,and he died on day 60.CONCLUSION Physicians should be aware of the potential fatal adverse effects of crizotinib.展开更多

Since thoracophrenolaparotomy should be helpful during liver resection for some of these patients, simultaneous removal of right lung metastases can be proposed through this approach. Eleven consecutive patients（median age of 53 years） carrier of colorectal liver and lung metastases, underwent single session surgical resection of both liver and right lung lesions by means of J-shaped thoracophrenolaparotomy. The median number of liver metastases removed was 5（range 2-30） and of lung metastases removed was 2（range 1-3）. Lung metastases were located in the upper lobe in 1 patient, in the middle lobe in 2, in the lower lobe in 6, and in the upper and lower lobe in 2. Mortality and major morbidity were nil. Two patients had a minor morbidity： one had wound infection and bile leakage treated conservatively and the other had transient fever. Mean overall survival was 24.4 months. An aggressive surgical approach should be undertaken for colorectal metastases： in case of multifocal liver disease with complex presentations, J-shaped thoracophrenolaparotomy could be considered as safe approach for combined liver and right lung metastasectomies.展开更多

Most of the levels are lower than 400 ug/L. Following biopsies of lung and liver neoplasms, one patient with a clinical diagnosis of lung cancer plus liver metastasis was pathologically diagnosed having an adenocarcinoma. His serum AFP value was 100-300 times the normal value. In order to further explore the clinical significance of an elevation of the AFP level in patients with lung adenocarcinoma plus liver metastasis, and to precisely distinguish a simple liver metastasis from lung adenocarcinoma or from lung hepatoid adenocarcinoma （HAC）, a clinical analysis of the patient, and a literature review was conducted.展开更多

Therefore, we thank again theauthors for their interest to our report, and furthermore we congratulatefor the original management of the shared clinical case.However, the condition recalled by the authors is related to a scenariooncologically and surgically at the opposite side of that discussedin our paper and for that somehow suggesting a comparisonis misleading.
文摘Granulosa cell tumor(GCT)is the most common sex cordstromal tumor,comprising 5%of all ovarian malignancies[1].The disease course is indolent,and the majority of cases present at stage 1.However,metastases may develop with potential sites being peritoneum,lung,brain,liver and bone[2].Due to the rarity of the disease,published evidence for management of granulosa cell tumor liver metastases(GCTLM)is limited.Surgical resection is the optimal treatment in instances where there is a high chance of achieving complete resection[3].With regards to unresectable GCTLM there is a paucity of evidence to guide treatment strategy.
文摘Liver fire invading the lung (also called wood-fire torturing metal) is widely seen in various respiratory diseases.In order to understand this pattern well,from the perspective of the five elements theory and zang-fu theory in Chinese Medicine,we systematically reviewed and discussed the physiological and functional characteristics of the liver and lung,the liver -lung relationship,the pathogenesis and identification of the pattern,as well as the commonly used basic formulas for the treatment of this pattern,including White-Draining Powder (Xiè Bái Sǎn,泻白散),Liver Heat-Dissolving Decoction (Huà Gān Jiān,化肝煎),Indigo and Clam Shell Powder (Dài Ge Sǎn,黛蛤散)and Hemoptysis-Relieving Formula(KéXuè Fāng,咳血方).Two examples of clinical modifications of these formulas in the treatment of hemoptysis and asthma are provided in this article.It should be noted that in the treatment of pulmonary diseases,these formulas should be used flexibly,and modified in accordance to the condition of the patient.
