Background and objective Small cell lung cancer (SCLC) is a rapidly growing tumor with character-istic of neuroendocrine cellular function. Neuron speciifc enolase (NSE), pro-gastrin-releasing peptide (ProGRP) and lactic dehydrogenase (LDH) are valuable in diagnosis and treatment of SCLC. By analyzing the variation of NSE, ProGRP and LDH before and atfer treatment, the aim of this study is to investigate the effcacy of tumor markers in diagnostic staging, therapeu-tic evaluation and prediction of disease relapsing.Methods Patients with SCLC who receiving the ifrst line chemotherapy in Cancer Hospital, Chinese Academy of Medical Sciences were enrolled and retrospectively analyzed. Clinical characteristic (includes NSE, ProGRP and LDH level before and atfer 2 cycles chemotherapy), effcacy evaluation, progression-free survival (PFS) were analyzed.Results Before treatment, Serum NSE, ProGRP and LDH in patients with extensive disease (ED) were signiifcantly higher than those with limited disease (LD)(allP<0.005); NSE level increased obviously accompanied by increase of lymph nodes stage in LD group (P=0.010); Patients with weight reduction when diagnosis had higher NSE and LDH than those without loss of weight (P=0.032,P=0.014). Atfer 2 cycles chemotherapy, decrease of NSE and ProGRP in effective group was higher than which in stable and ineffective groups (P=0.015,P=0.002). hTe relapse risk was lower in patients who accepted>4 cycles chemotherapy and with obvious decrease of ProGRP than those who accepted ≤4 cycles chemotherapy and with less obvious decrease of ProGRP in LD group; ED patients with no more than 2 distant metastasis, normal LDH level before treat-ment and obvious decrease of ProGRP atfer chemotherapy had lower short term relapse risk. In addition, the types of relapse (sensitive relapse, drug resistance relapse and refractory relapse) were negatively correlated with decrease of ProGRP (P=0.044). By multivariate analysis, numbers of chemotherapy cycle was independent prognostic factor for PFS in LD SCLC; numbers of distant metastasis and decrease of ProGRP were independent prognostic factors for PFS in ED SCLC.Conclusion Increase level of serum tumor markers is related to tumor burden. Decrease level of ProGRP atfer treatment may prognose effcacy and relapse risk.

Background and objective As the prevalence of tobacco and the aging of the population, the incidence of lung cancer in the elderly rises. However, few elderly patients (older than 70 years old) with lung squamous cell carcinoma were involved into the clinical trials, which offered insuffcient clinical evidence for these patients. Lung squamous cell carcino-ma patients older than 80 years old were included in our study to analyze the clinical characteristics, treatment and prognostic factors, and to explore the optimal treatment choices for these patients.Methods We retrospectively analyzed the clinical fea-tures of 38 elderly patients with lung squamous carcinoma and summarized the treatment under the clear diagnosis and clini-cal staging.Results Elderly patients with squamous cell carcinoma can choose surgery, radiotherapy and chemotherapy based on diagnosis and clinical staging when their physical condition is permitted.Conclusion Because of the short life expectancy of patients more than 80 years old, fewer of them could receive completed and effective treatment, comparing with patients between 70 and 80 years old.

Objective This study focuses on the construction and cultivation of young administrative management per-sonnel in Shanghai's public hospitals,aiming to provide scientific support for the development of high-quality young administra-tive management professionals in public hospitals.Methods Utilizing an anonymous online survey,this research collected data on the current state of subjective well-being and its influencing factors among the targeted groups from hospitals.Analysis of vari-ance and multivariate analysis were conducted to analyze potential factors affecting their sense of well-being.Results A total of 171 cases were included in the survey,with an average score of 80.37.This group of respondents exhibited a higher level of sub-jective well-being compared to the national norm.Notably,young administrative staff who had obtained Shanghai residency,had a surplus income,spent time with family after work,had career advancement opportunities,felt a strong connection to their work's value,and received affirmation from family members,demonstrated higher subjective well-being scores,with significant statisti-cal differences(P＜0.05).Conversely,those with an income ranging from 0 to 100 000,and those who felt overwhelmed by their current roles,scored lower on well-being,with significant statistical differences(P＜0.05).Conclusion This study sug-gests that by bolstering professional security and job stability,fostering a set of correct values and a sense of work identity,and improving job satisfaction and competence,the subjective well-being of this group can be further elevated.This,in turn,can in-ject new momentum into the high-quality development of public hospitals.

Objective To investigate the relationship between impaired glucose regulation (IGR) and slow flow or no reflow (SF/NRF) during percutaneous coronary intervention (PCI) in patients with ST segment elevation myocardial infarction (STEMI). Methods Clinical materials of 80 STEMI patients with SF/NRF and 84 STEMI patients without SF/NRF in the hospital from October 2021 to October 2022 were retrospectively collected, including blood glucose, total cholesterol (TC), triglyceride (TG), cardiac troponin Ⅰ (cTnⅠ), fibrinogen, left ventricular ejection fraction (LVEF), D-dimer, uric acid, homocysteine, the ratio of absolute value of neutrophils to absolute value of lymphocytes (NLR), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and 2 h postprandial blood glucose level. Logistic regression model was used to analyze the influencing factors of SF/NRF in STEMI patients with PCI; the receiver operating characteristic (ROC) curve was used to analyze the diagnostic value of fasting blood glucose and 2 h postprandial blood glucose levels for SF/NRF in STEMI patients with PCI. Results Compared with non-SF/NRF group, the levels of cTnⅠ, fibrinogen and HDL-C in SF/NRF group were significantly higher, while the levels of systolic blood pressure (SBP), diastolic blood pressure (DBP) and NLR were significantly lower (P < 0.05). Compared with non-SF/NRF group, the stent diameter, stent length and the time from chest pain to catheter room in SF/NRF group were significantly longer (P < 0.05). The levels of fasting blood glucose and 2 h postprandial blood glucose in SF/NRF group were significantly higher than those in non-SF/NRF group (P < 0.05). Logistic regression analysis showed that fasting blood glucose and 2 h postprandial blood glucose were the influencing factors of SF/NRF in STEMI patients with PCI, and the area under the curve (AUC) of the combination of the two indicators for diagnosis of SF/NRF in STEMI patients during PCI was significantly higher than that by fasting blood glucose and 2 h postprandial blood glucose alone (Z=3.272, 4.369, P < 0.001). Conclusion IGR is related to SF/NRF during PCI in STEMI patients, and fasting blood glucose and 2 h postprandial blood glucose levels are the influencing factors of SF/NRF in STEMI patients.

BACKGROUNDChemotherapy is the main treatment measure of advanced non-small cell lung cancer(NSCLC).The aim of this study is to explore the efficacy,toxicity,time to disease progression(TTP) and overall survival under the combined chemotherapy with gemcitabine(GEM) plus cisplatin(DDP) in the treatment of advanced NSCLC.

METHODSRetrospective review was conducted on 79 chemotherapy-naive cases of advanced NSCLC treated with GEM and DDP from October 1999 to November 2005.Among 79 patients,51 were male and 28 female;the median age was 53 years old(ranged from 21 to 74);there were 17 cases of squamous cell carcinoma,53 cases of adenocarcinoma,3 cases of large cell carcinoma,1 case of adeno-sqamous cell carcinoma,5 unidentified cases;there were 26 cases in IIIB stage and 53 cases in IV stage according to AJCC 1997 standard.All patients received GEM 800-1250 mg/m² on days 1 and 8 and DDP 75-80 mg/m² on day 1 or 30 mg/m² for three days by intravenous administration,with 21 days as one cycle.Each patient received 2-4 cycles chemotherapy.

RESULTSThe total clinical reponse rate(complete and partial response) was 31.6%,and clinical benefit rate(complete and partial response and stable disease) was 73.4%.1-year survival rate was 64.9%,2-year survival rate was 32%.After median follow-up of 2.33 years,median TTP was 5.06 months.The main toxicities were nausea,vomitting and hematological toxicities.The rates of grade III to IV leukopenia and thrombocytopenia were 25.4% and 31.6% respectively.Other toxicities were slight and tolerable.

CONCLUSIONSCombined chemotherapy with GEM plus DDP as first-line treatment to advanced NSCLC is an effective and feasible regimen,which is one of the standard regimens.For old patients,this regimen is a good choice.The fit dosage of GEM for Chinese is 1000 mg/m².

BACKGROUNDGensing Rg3 is an active component from ginseng. The aim of this study is to observe the clinical anticancer effect of Rg3 in combination with chemotherapy regimen NP (vinorelbine+cisplatin) in advanced non-small cell lung cancer (NSCLC).

METHODSStage III-IV NSCLC patients confirmed by pathology or cytology all received vinorelbine plus cisplatin for at least two cycles, and were randomized into two groups: patients in arm A also received placebo twice a day, while patients in arm B received two tablets of Rg3 twice a day for at least two months. The endpoints of the study were the efficacy, survival and tolerance of patients.

RESULTSFrom July 2000 to May 2002, 115 patients were enrolled into the trial. The patients' characteristics were well balanced in the two groups. Sex of patients: male, 79; female 36. Types of pathology: adenocarcinoma, 71; squamous cell carcinoma, 29; adenosquamous carcinoma, 8; others, 7. TNM stage: stage III, 45; stage IV, 70. Prior chemotherapy: with, 17; without, 98. Prior radiotherapy: with, 15; without, 100. Prior surgical treatment: with, 23; without, 92. Nine patients discontinued from the trial due to severe adverse effects (5) and other reasons (4), so there were 106 patients evaluable for clinical efficacy. The response rate was 14.5% (8/55) in arm A, and 33.3% (17/51) in arm B (P=0.011). The survival time in arm A was 9.7 months (mean) and 8.0 months (median), and 15.3 months (mean) and 10.0 months (median) in arm B (P=0.0088).

CONCLUSIONSPreliminary results show improvements in response rate and survival time (median and mean) in Rg3 arm compared with placebo arm. It is worthy to confirm the results in further clinical trials.

Objective To observe the safety and short?term efficacy of sigle drug albumin?bound paclitaxel (ABP) in the treatment of elderly patients with advanced non?small cell lung cancer (NSCLC). Methods A total of 23 elderly patients with advanced NSCLC who received weekly ABP regimen (130 mg/m2/week) in our hospital from October 2011 to March 2014 were retrospectively evaluated. The short?term efficacy, progression?free survival ( PFS) , and overall survival ( OS) were analyzed. Results The median treatment period was 4 cycles (2?10 cycles). Partial response, stable disease, progressive disease, overall response rate, and disease control rate were 26.1%, 43.5%, 30.4%, 26.1% and 69.6%, respectively. The median PFS was 5.33 months (95% CI:2.95?7.70 months), while the median OS was 40.33 months (95% CI:29.82?50.83 months). Major adverse events included leucopenia (82.6%), neutropenia (78.3%), nausea or vomiting (56.5%), fatigue (52.2%), peripheral neuropathy (26.1%), myalgia/arthralgia (30.4%), thrombocytopenia ( 13. 0%) and arrhythmia ( 4. 3%) . The patients accompanied with chronic diseases had significantly higher incidence rate of peripheral neuropathy and myalgia/arthralgia compared with the patients without accompanied chronic diseases ( 50. 0% vs. 9. 1% and 66. 7% vs. 9. 1%, P<0. 05 for both ) . Conclusion The weekly single drug ABP regimen is effective and well?tolerated in elderly patients with advanced NSCLC.

Objective The aim of this study was to analyze the trend of incidence, clinicopathological characteristics and therapy of young ( less than 40 years old) patients with advanced lung adenocarcinoma, and to identify the prognostic factors. Methods The clinical data of 198 young patients with advanced lung adenocarcinoma were collected from the Cancer hospital and Institute of Chinese academy of Medical Sciences from January 2001 to June 2012. To analyze the trend of incidence, clinicopathological characteristics and therapy and evaluate the independent prognostic factors affecting survival time with Cox proportional hazards model. Results From 2001 to 2012, the incidence of lung adenocarcinoma in young patients was increased year by year. Among the 198 patients, 92 were males and 106 were females. Their age was from 20 to 40 with a median age of 34 years. Most patients had poorly differentiated adenocarcinoma ( 46. 7%) whereas 36.7% of the cases had moderately differentiated tumor. Among the 198 patients, there were 25 patients with stage ⅢB ( 12. 6%) and 173 ( 87. 4%) cases of stage Ⅳ cancer. The 1?, 3? and 5?year survival rates were 70. 7%, 21. 6% and 10. 3%, respectively. Among the198 cases, patients who received epidermal growth factor receptor?tyrosine kinase inhibitor ( EGFR?TKI ) therapy, the median OS ( 25. 6 months) was significantly longer than that of patients who never received EGFR?TKI therapy (13.3 months) (P<0.001). Since 2009, the number of cases detected for EGFR gene was gradually increased, and the median OS of patients diagnosed from 2010 to 2012 was 22 months, significantly higher than that of 16 months of patients diagnosed during 2001?2009 (P=0.019). The Cox regression analysis showed that the performance status, extra?pulmonary metastasis and whether received EGFR?TKI therapy were independent prognostic factors. Conclusions The incidence rate of lung adenocarcinoma in young patients has an increasing trend. They have a high proportion of women and of poor differentiation. The patients can get benefits from EGFR?TKI therapy. Mutivariate Cox regression analysis shows that the performance status, extra?pulmonary metastasis and whether received EGFR?TKI therapy are independent prognostic factors for young patients with advanced lung adenocarcinoma.

Background and objective At present no standard second-line combination has been established for recurrent small cell lung cancer (SCLC). hTerefore we evaluate the effcacy and safety of irinotecan in combination with nedapla-tin/cisplatin against refractory or relapsed small cell lung cancer. Methods In this retrospective study, we analyzed the data of 1,140 patients who diagnosed small cell lung cancer at our hospital from April 2009 to April 2012. Of all the patients, 34 patients were treated with irinotecan and nedaplatin (irinotecan 60 mg/m2 on days 1, 8 nedaplatin 85 mg/m2 day 1, every 3 weeks) , and 20 patients were treated with irinotecan and cisplatin (irinotecan 60 mg/m2 on days 1, 8 cisplatin 75 mg/m2 day 1, every 3 weeks) as the second-line treatment. Prognostic factors of overall survival (OS) were estimated by Kaplan-Meier and Cox's Regression-proportional hazards model. Results Of all the 54 eligible patients, median progression free survival (PFS) was 4.9 months, and median OS was 13.3 months. Median PFS was 5.4 months for irinotecan plus nedaplatin (IN) and 4.9 months for irinotecan plus cisplatin (IC), respectively (P=0.465). Median OS was 14.3 months and 13.3 months, respectively (P=0.704). In multivariate analysis, ECOG PS, number of metastases and cycles of chemotherapy were independent prognostic factors. hTe toxicities were mild, while toxicity proifle was slightly different for each of the arms:hematologic toxicity was higher in IN group, and diarrhea was higher in IC group. Conclusion Irinotecan plus platinum is effective and tolerable for refractory and relapsed small cell lung cancer. Irinotecan plus nedaplatin is non-inferior to irinotecan plus cisplatin in terms of effcacy and safety.

Background and objectiveSmall cell lung cancer combined with squamous cell carcinoma are rare. hTe aim of this study was to analyze the clinicopathological characteristics and treatment, and explored the prognostic factors of this disease.MethodsBetween January 2004 and December 2012, 58 patients with cytopathologically conifrmed small cell lung cancers combined with squamous cell carcinoma were retrospectively analyzed.Kaplan-Meier methods were used to calculate the survival rate, andLog-rank test was used to examine differences between arms. hTeCox regression model was used to analyze the independent factors affecting the overall survival (OS).Results hTe OS of the 58 patients was 22.7 months with a range of 0.3 to 124.3 months. In univariate analysis, Karnofsky performance score before treatment, extensive disease, tumor stage were the considered prognostic factors affecting the OS rate (P<0.05).Cox multivariate analysis showed that only the tumor-node-metastasis (TNM) stage was the independent prognostic factor (P=0.019). hTe majority of the patients received multimodality therapy and chemotherapy was the main treatment. Distant metastasis was the main reasonfor the treatment failure.ConclusionCombined therapy with chemotherapy as the main treatment should be adopted in therapeutic regimen of the patients with small cell lung cancers combined with squamous cell carcinoma. TNM stage was the independent prognos-tic factor inlfuencing the OS.
