Liver fibrosis is a major disease that affects human health. Currently,drugs used for the treatment of hepatic fibrosis have such problems as low drug solubility,lack of liver specificity and possible occurrence of side-effects. In order to improve the anti-fibrosis therapeutic efficacy,various nano-drug delivery systems and targeting strategies are explored in liver fibrosis therapy. This review summarizes the drug delivery systems and targeting strategies that have been applied to liver fibrosis therapy in recent years from the types of carriers and modified ligands,which serve as a basis of designing safe and effective drug delivery systems for liver fibrosis therapy.

Objective To investigate the molecular characteristic of fluoroquinolone resistant Streptococcus agalactiae (GBS) isolates in Suzhou.Methods Totally 46 fluoroquinolone resistant GBS strains were collected,and then subjected into PCR and two resistance genes were sequenced and their high frequency mutation sites,gyrA and parC were analysed.Results Among these isolates,the most frequent gyrA mutation was gyrA_S81L (TCA→TTA),which displayed 93.4％ (43/46) with substituted at No.81 site of amino acid from Ser to Leu.However,the most frequent parC mutation was mutated at No.79 site of amino acid from Ser to Tyr orPhe,with two mutations parC_S79Y (73.9％,34/46) and parC_S79F(17.4％,8/46).The analysis showed that the major mutation patterns are gyrA_S81L with parC_S79Y (73.9％,34/46),gyrA_S81L with parC(13.0％,6/46).Conclusion The most frequent mutations of fluoroquinolone resistant gene in Suzhou are gyrA and parC and the major mutation patterns are gyrA_S81L/parC_S79Y and gyrA_S81L/parC_S79F.

ABSTARCT Purpose To investigate the clinicopathologic characteristics and genetic mutations of metastatic follicular thy-roid carcinoma(FTC).Methods A total of 22 cases of meta-static FTC were collected,including previous medical history,imaging,treatments and outcomes,and next-generation sequen-cing study and Sanger sequencing were performed in 12 cases.Results There were 16 women and 6 men.Sixteen cases were older than 50 years.Seven cases presented with metastases as the first symptom.Fourteen cases developed metastases 3 to 12 years after thyroid surgery.Sixteen cases developed bone metas-tasis,10 cases had lung metastasis,and 3 cases had brain me-tastasis.Those patients with multiple bone metastases progressed during the follow-up period.The common gene mutations in me-tastases were NRAS p.Q61R(6 cases),HRAS p.Q61R(2 ca-ses)and KRAS p.Q61R(1 case),followed by TERT promoter mutation(8 cases).Other mutated genes included KEL,BRCA1/2,ALK,ROS1,ErbB4,etc.Conclusion FTC has a high misdiagnosis rate.Those diagnosed with FTC should under-go regular systemic examinations to detect potential metastasis,especially in bone,lung,and brain.Further research on the sig-nificance of NRAS and other molecular indicators in FTC metas-tasis will help to better predict its biological behaviors.

Objective To study the diagnostic value of endoscopic ultrasound guided fine needle aspiration (EUS-FNA) combined with the new category of papanicolaou society of cytopathology in solid pancreatic lesions (SPL) rapid on-site evaluation (ROSE).Methods From February 2011 to October 2014,225 patients with SPL who underwent EUS-FNA and obtained the cytological diagnosis were enrolled.The lesions were finally diagnosed according to pathological results,imaging and follow-up data,and then the sensitivity,specificity,and accuracy of EUS-FNA in the diagnosis of SPL were calculated based on the new papanicolaou society of cytopathology terminology.Logistic stepwise regression analysis was performed to analyze the risk factors.Results Among 225 patients with SPL,96 cases (42.7％)had uncertain cytological diagnosis,17.3％ (39/225) could not be diagnosed,8.0％ (18/225) were atypical lesions,and 17.3％ (39/225) were suspicious malignant carcinomas.Among 129 cases (57.3％)with certain cytological diagnosis,15.1％ (34/225) were benign lesions,14.7％ (33/225) were tumors (benign or others) and 27.6％ (62/225) were malignant tumors.When atypical lesions were added into non-tumor lesions or tumor lesions,the sensitivity,specificity and accuracy of diagnosis were 87.3 ％,91.7％,88.2％,and 94.7％,72.2％,90.3％,respectively.Serum CA125≥14 kU/L (odds ratio (OR) =7.13,95％ confidence interval (CI) 2.02 to 25.22,P=0.002) and history of biliary disease (OR=3.85,95％CI 1.22 to 12.51,P=0.022) were two independent risk factors of pancreatic tumors.Conclusions Despite of a high percentage of uncertain cytological diagnosis,EUS-FNA still has high diagnostic value in SPL when combined with the new papanicolaou society of cytopathology terminology.Furthermore,serum CA125≥14 kU/L and history of biliary disease may help to diagnose pancreatic tumors.

Objectives:To compare the effects of manual and mechanical chest compression on patients receiving extracorporeal cardiopulmonary resuscitation (ECPR).Methods:Patients who underwent extracorporeal cardiopulmonary resuscitation admitted to Jinhua Municipal Central Hospital, Hangzhou First People's Hospital and the First Hospital of Jiaxing from September 2014 to July 2022 were enrolled in the study. The patients were divided into the manual group and mechanical group according to the compression method, and the clinical data of the two groups were compared. To explore the effects of the two compression method on the ECPR implementation, proportion of return of spontaneous circulation (ROSC) and hospital survival.Results:A total of 108 patients who underwent ECPR were included in the study, 50 patients in the manual group and 58 patients in the mechanical group. There were no significant differences in sex, age, laboratory tests before ECPR, ROSC proportion (90.0% vs. 86.2%) and survival (34.0% vs. 39.7%) between the two groups (all P>0.05). The puncture time in the mechanical group was shorter than that in the manual group [12 (9,15) min vs. 13 (11,16) min, P<0.05]. Conclusions:Compared with manual compression, mechanical compression during ECPR neither increase the probability of ROSC nor reduce in-hospital mortality in patients with cardiac arrest. However, mechanical compression may help to shorten the puncture time.

Objective To compare the therapeutic effects between three-dimensional conformal radiotherapy (3DCRT) and intensity-modulated radiotherapy (IMRT) in patients with stage Ⅱ/Ⅲ esophageal cancer and investigate the prognostic factors.Methods Medical record of 2 132 patients with stage Ⅱ/Ⅲ esophageal cancer who underwent definitive radiotherapy with/without chemotherapy in 10 hospitals from January 2002 to December 2016 from were retrospectively analyzed.Among these patients,37.9％ of them were aged ≥ 70 years,33.9％ with neck and upper esophageal tumors and 66.1％ with middle and lower esophageal and borderline tumors.The median gross tumor volume (GTV) and lymph node gross tumor volume (GTVnd) was 41.6 cm3.Among them,32％ were stage Ⅱ] and 68％ were stage Ⅲ.A total of 723 patients received 3DCRT and 1 409 cases received IMRT.Patients received an equivalent dose in 2 Gy (EQD2) ≥ 60 Gy accounted for 86.1％,and 41.1％ of them received concurrent chemoradiotherapy.Results The median follow-up time was 60.8 months.The 1-,3-and 5-year overall survival (OS) of all patients was 73.9％,41.7％ and 32.6％,and the 1-,3-and 5-year progression-free survival (PFS) was 62.2％,37.3％ and 32％,respectively.Multivariate analysis demonstrated that age,primary tumor location,clinical stage,tumor target volume,EQD2 and concurrent chemoradiotherapy were the independent prognostic factors for OS.Age,primary tumor location,clinical stage,tumor target volume and EQD2 were the independent prognostic factors for PFS.The OS and PFS did not significantly differ among the low-risk,low-/moderate-risk,moderate-/high-risk and high-risk groups according to age≥70 years,tumor diameter＞5 cm,tumor volume ≥41.6 cm3 and stage Ⅲ (P＜0.001).After the propensity score matching (PSM) method,neither 3DCRT nor IMRT yielded significant advantages in OS or PFS (P=0.971;P=0.658).However,IMRT tended to yield survival benefits in low-risk patients (P=0.125).Conclusions Both 3DCRT and IMRT yield relatively high OS rate in patients with stage Ⅱ/Ⅲ esophageal cancer.The prognosis model established in this investigation can properly predict the survival of patients.Low-risk patients tend to obtain survival benefits from IMRT.

Objective To retrospectively analyze the effect of tumor length on the prognosis in stage Ⅱ/Ⅲ esophageal squamous cell carcinoma (ESCC) patients treated with definitive radiotherapy and to evaluate the role of tumor length in clinical stage for non-operative ESCC patients.Methods The data of 2 086 ESCC patients who were treated with definitive radiotherapy from 2002 to 2016 in 10 hospitals (3JECROG) were analyzed.The effect of tumor length on overall survival (OS) was analyzed and stratified analysis of tumor length was done in different stages of ESCC.Results The median OS and median progression-free survival (PFS) time of the whole group were 25.6 months and 18.2 months respectively.The Cox multivariate analysis showed that treatment moda,aga,alinical stage and tumor length were independent prognostic factors.The median,1-,3-,and 5-year OS were 28.9 months,77.3％,45.0％,and 36.3％ versus 21.9 months,69.9％,37.9％,and 28.1％ for patients with ≤ 5 cm and patients ＞ 5 cm respectively (P＜0.05).For stage Ⅱ patienta,abe median OS were 42.1 and 38.9 months respectively in ≤ 5 cm group and＞5 cm group (P=0.303).And for stage Ⅲ patienta,abe median OS were 23.9 and 19.3 months respectively in ≤5 cm group and＞5 cm group (P＜0.001).The median OS with N1was 24.1 and 18.4 montha,aespectively in ≤5 cm group and＞5 cm group (P＜0.001).Conclusions The tumor length was an independent prognostic factor for stage Ⅱ/Ⅲ patients treated definitive radiotherapy.The tumor length may be helpful in clinical staging of ESCa,aspecially for stage Ⅲ and N1.

Objective To evaluate the survival and prognostic factors of esophageal cancer treated with definitive ( chemo ) radiotherapy by applying novel radiation techniques including three-dimensional conformal radiotherapy (3DCRT) or intensity-modulated radiotherapy (IMRT). Methods Clinical data of 2762 patients with non-operated esophageal squamous cell carcinoma who underwent definitive ( chemo ) radiotherapy from 2002 to 2016 in 10 hospitals were retrospectively analyzed.The prognostic factors were also identified and analyzed. Results The median follow-up time was 60. 8 months. The 1-, 2-, 3-and 5-year overall survival (OS) of all patients was 71. 4％,48. 9％,39. 3％,and 30. 9％,respectively.The 1-,2-,3-and 5-year progression-free survival (PFS) was 59.5％,41.5％,35.2％,and 30％,respectively.The median survival was 23 months.The median time to progression was 17. 2 months.Multivariate analysis demonstrated that age, primary tumor location, clinical stage, tumor target volume, EQD2 and treatment mode were the independent prognostic factors for OS.Primary tumor location,clinical stage,tumor target volume and EQD2 were the independent prognostic factors for PFS. Conclusions In this first large-scale multi-center retrospective analysis of definitive ( chemo) radiotherapy for esophageal squamous cell carcinoma in China, the 5-year OS of patients with esophageal squamous cell carcinoma is significantly improved by 3DCRT, IMRT combined with chemotherapy drugs. However, the findings remain to be validated by prospective clinical trials with high-level medical evidence.
