Objective Purpose understanding the prevalence of diabetes(DM) of Xuzhou mine workers and impacts on the incidence of risk factors, and discussing the prevention and treatment.Methods From November 2007 to March 2008,1180 Xuzhou mine workers were determinated by height,weight,abdominal circumference,blood pressure,fasting plasma glucose and lipid four(including triglycerides ,total cholesterol,low-density lipoprotein cholesterol, high-density lipoprotein cholesterol), OGTT test.Results DM prevalence rate is 5.25 percent,more men than women;prevalence rate under 40 years old is lower,the prevalence rate from 40 to 50 year-old began to increase, to the top of 50-year-old.Overweight and obesity people took the most part.Conclusion DM is a common diseases among Xuzhou mining area in-service workers with high rates of prevalence,it connected with age,family history, occupation,body mass index(BMI),etc.

Objective:To investigate the progression pattern of acquired resistance to osimertinib and the treatment method as well as the therapeutic effect of salvage therapy in advanced lung cancer patients with epidermal growth factor receptor (EGFR) sensitive mutation or T790M mutation after the treatment of tyrosine-kinase inhibitor (TKI).Methods:The data of 145 patients with advanced lung cancer treated with osimertinib in Jiangsu Cancer Hospital between April 2017 (the approval time of osimertinib in China) and May 2019 were collected. At the last follow-up (December 2019), a total of 87 (60.0%) patients had acquired resistance to osimertinib, 61 (70.1%) of whom received salvage treatment; for patients with dramatic progression after resistance, chemotherapy was mainly given in the salvage therapy; for patients with gradual or local progression after resistance, the continuing targeted drug therapy and the local therapy were given. Imaging evaluation and Kaplan-Meier method were used to analyze the progression pattern of acquired resistance to osimertinib and the survival status, and to compare the salvage treatment results among subgroups.Results:The median follow-up time of 61 patients receiving salvage therapy was 11 months (4-32 months), among which 58 (95.1%) patients again had resistance to osimertinib, and 24 (39.3%) patients died of lung cancer. The median progression-free survival (PFS) time and overall survival (OS) time for the whole cohort was 2.5 months (95% CI 2.1-3.0 months) and 19.0 months (95% CI 13.7-26.3 months), respectively. The 1-year and 2-year OS rate was 72.1% and 41.7%, respectively. Among 61 patients receiving salvage therapy, 8 (13.1%) , 30 (49.2%) and 23 (37.7%) cases had dramatic progression, gradual progression and local progression, respectively; when given timely and proper salvage treatment, there were no statistically differences in PFS and OS of the patients in the above three subgroups (all P>0.05). There were no statistically differences in PFS and OS between patients receiving local therapy (24 cases) and patients not receiving local therapy (37 cases) after the progression occurred (all P>0.05). Among 58 patients with resistance to osimertinib again after the salvage therapy, 6 patients with gradual or local progression had more than 6-mouth PFS after the salvage therapy. Conclusions:Dramatic, gradual and local progression are the main patterns in patients with acquired resistance to osimertinib. The therapeutic efficacy of salvage therapy still shows some disappointing results.

Objective To investigate the effect of lung protective and ventilatory management strategies for brain death donors on eligibility and availability of lungs for transplantation.Method The clinical data of two brain dead patients who accepted lung protective ventilatory management strategies from Feb.2015 to Mar.2015 were retrospectively analyzed.Two cases of brain-dead patients,due to severe cerebral trauma,accepted the aggressive lung protective ventilatory management strategies and airway management for 9 days and 4 days respectively.PaO2/FiO2,chest imaging manifestations,surface of the lung harvested and pulmonary rehabilitation of recipients after operation were observed.Result Two lung recipients were liberated from ventilation and pulmonary function improved significantly after double lung transplantation.Conclusion The application of lung protective ventilatory strategies in potential organ donors with brain death can increase the number of eligible and harvested lungs.

Objective: Non-small-cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR)-activating mutations have higher response rate and more prolonged survival following treatment with single-agent EGFR tyrosine kinase inhibitor (EGFR-TKI) compared with patients with wild-type EGFR. However, all patients treated with reversible inhibitors develop acquired re-sistance over time. The mechanisms of resistance are complicated. The lack of established therapeutic options for patients after a failed EGFR-TKI treatment poses a great challenge to physicians in managing this group of lung cancer patients. This study evaluates the in-fluence of EGFR-TKI retreatment following chemotherapy after failure of initial EGFR-TKI within at least six months on NSCLC pa-tients. Methods:The data of 27 patients who experienced treatment failure from their initial use of EGFR-TKI within at least 6 months were analyzed. After chemotherapy, the patients were retreated with EGFR-TKI (gefitinib 250 mg qd or erlotinib 150 mg qd), and the tumor progression was observed. The patients were assessed for adverse events and response to therapy. Targeted tumor lesions were as-sessed with CT scan. Results:Of the 27 patients who received EGFR–TKI retreatment, 1 (3.7%) patient was observed in complete re-sponse (CR), 8 (29.6%) patients in partial response (PR), 14 (51.9%) patients in stable disease (SD), and 4 (14.8%) patients in progres-sive disease (PD). The disease control rate (DCR) was 85.2%(95%CI=62%-94%). The median progression-free survival (mPFS) was 6 months (95%CI=1-29). Of the 13 patients who received the same EGFR-TKI, 1 patient in CR, 3 patients in PR, 8 patients in SD, and 2 patients in PD were observed. The DCR was 84.6%, and the mPFS was 5 months. Of the 14 patients who received another EG-FR-TKI, 0 patient in CR, 6 patients in PR, 6 patients in SD, and 2 patients in PD were observed. The DCR was 85.7%, and the mPFS was 9.5 months. Significant difference was found between the 2 groups in progression-free survival but not in response rate or disease control rate. Conclusion:Retreatment of EGFR-TKIs can be considered an option after failure of chemotherapy for patients who were
previously controlled by EGFR-TKI treatment.

Objective? To explore the family function of stroke patients and their rehabilitation exercise compliance level, as well as the correlation between them. Methods? By convenience sampling, totally 400 stroke patients undergoing re-examination in Department of Neurology, a ClassⅢ Grade A hospital in Zhejiang Province from June 15th, 2018 to December 15th 2018 were selected as the research objects. General Information Questionnaire, Questionnaire of Exercise Adherence(EAQ),Family Assessment Device(FAD) were adopted in the study. A total of 400 questionnaires were distributed and 389 valid ones were collected. Results? The 389 stroke patients had a total score of (37.07±11.55) in EAQ and (115.78±32.75)in FAD. The dimensional scores in family function(except emotional intervention) were negatively correlated with the total score of rehabilitation exercise compliance (P＜ 0.05). The total score of FAD was negatively correlated with each dimensional scores of EAQ (P＜ 0.05). Multivariate linear regression analysis indicated that, problem-solving, communication, role, emotional reaction, behavior control and the overall family function were the influencing factors of the patient's exercise compliance (P＜ 0.05). Conclusions? The stroke patients' family function and rehabilitation exercise compliance have great space to improve. For those with good family function, their rehabilitation exercise compliance is also good. Improving family function, especially coming up with effective problem-solving plan, is the effective way to improve the stroke patients' rehabilitation exercise compliance.

Objective: To analyze the effects of 12week highintensity fitness exercise on body composition,lipid metabolism and gut microbiota in obese adolescents, so as to provide references for improving the health levels of obese adolescents. Methods: From January to June 2023, 20 obese adolescents from Huaifeng Vocational and Technical School in Huaian City were recruited for the study. Participants were assigned to an exercise group (n=10) and a control group (n=10) for a 12week exercise intervention by random number table method, and both groups had the same diet during the intervention period. The exercise group engaged in three exercises every week, mainly consisting of moderate to highintensity aerobic exercise combined with highintensity intervals. In the first week, there was a 30 minutes of aerobic exercise, followed by 10 minutes of highintensity interval training in the total intervention time each week, and the rest of the time was aerobic exercise with a total intervention time of 60 minutes to maintain; the control group did not receive specific interventions. Body composition was measured using bioelectrical impedance analysis, and lipid levels were determined using an automatic biochemical analyzer. The expression levels of serum inflammatory factors were measured at baseline and after 12 weeks of intervention, and gut microbiota was analyzed using 16S rRNA gene sequencing. Statistical analysis was performed using t test and Chisquare test. Results: After 12 weeks of intervention, the levels of triglycerides (TG), and lowdensity lipoprotein cholesterol (LDL-C) in obese adolescents in the exercise group decreased from (1.7±0.6, 3.5±0.8) mmol/L to (0.9±0.3, 2.6±0.4) mmol/L, while highdensity lipoprotein cholesterol (HDL-C) increased from (1.1±0.2) mmol/L to (1.4±0.2) mmol/L; and serum interleukin-1 receptor antagonist(IL-1Rn) decreased from (8.4±1.6) to (4.5±0.4) ng/mL in the exercise group (t=7.34,2.49,-3.05,2.56, P<0.05). The α-diversity results showed that the Chao index (268.00±22.67) and Ace index (243.98±38.64) in the exercise group were higher than those in the control group (184.52±19.28, 171.43±23.33), and the differences were statistically significant (t=2.48, 2.53, P<0.05). The Shannon index (5.36±1.41) in the exercise group was higher than that in the control group (4.73±1.12), and the Simpson index (0.78±0.10) was lower than that in the control group (0.89±0.10), but the differences were not statistically significant (t=1.83, -2.10, P>0.05). The β-diversity results showed that the intergroup differences in gut microbiota structure between the exercise group and the control group were greater than the intragroup differences, and the differences in gut microbiota structure between the exercise group and the control group were statistically significant (R2=0.083，P<0.05). After intervention, there were significant differences in the relative abundances at the levels of phylum, class, genus, and species in gut microbiota among obese adolescents between the exercise group and the control group (P<0.05). Conclusion The 12week highintensity fitness exercise can alleviate obesity symptoms in obese adolescents through the gut microbiota-lipid metabolism pathway and improve mild chronic inflammatory status.

Objective To summarise and analyse the qualitative studies on the factors that influence patient involvement in decision-making for the initial administration of insulin for the patients with Type II diabetes,from the perspectives of patients and healthcare staff in order to provide a reference to promote patient involvement in decision-making.Methods Systematic searches were conducted across databases,such as CINAHL,Cochrane Library,EMBASE,PubMed,Web of Science,PsycINFO,China National Knowledge Infrastructure(CNKI),Wanfang Data,VIP,and SinoMed,for qualitative studies on the factors that affect patient involvement in initial insulin decision-making for the patients with Type II diabetes.The search was limited to articles from the inception of the databases to 30th September,2023.Quality of the included studies was assessed using the Joanna Briggs Institute(JBI)evidence-based healthcare centre for qualitative research quality assessment tool.The results were integrated using a synthesising integration method.Results A total of 19 articles were included,yielding 20 study results,which were categorised into 7 themes of patient decision-making related values,patient role preferences in decision-making,condition of patient,the role of healthcare staff in patient participation in decision-making,professional quality of healthcare staff,relationship between patient and healthcare staff,and the support from a medical institution.The data were ultimately integrated into 4 overarching themes of patient personal factors,healthcare staff factors,patient-staff interaction factors and medical institution factors.Conclusion The involvement of the patients with Type II diabetes in the decision-making for the initial administration of insulin is influenced by patients themselves,healthcare staff and medical institutions.It requires efforts of multiple parties:not only with the patients actively participate in decision-making,but also with the healthcare staff and institutions who provide effective decision supports.

Objective To construct a culture system of endometrial organoids for infertility induced by non-immune or immune factors,and to compare the immune cytokines between them.Methods The samples were collected from infertility patients undergoing hysteroscopy in Department of Reproductive Medicine Center of The First Affiliated Hospital of Naval Medical University(Second Military Medical University).Endometrial tissues were obtained from patients with infertility caused by non-immune factors(n=3)and patients with repeated implantation failure(RIF)(n=5).The tissues were embedded in matrix glue for 3D culture after washing,digestion,re-suspension and plate attachment.The growth of endometrial organoids of the 2 groups was observed under inverted microscope;the expression of estrogen receptor,keratin and E-cadherin,which were specific endometrial markers,was detected by immunofluorescence staining;and the cytokines of the 2 groups were determined by enzyme-linked immunosorbent assay(ELISA)and the differences of cytokines between the 2 groups were observed.Results During the process of in vitro culture of endometrial organoids,the volume of organoids and the number of cells gradually increased.After 7-10 d of culture,the volume of organoids reached a stable state,and the shape gradually became a perfect circle.At the same time,the number of organoids from the infertility patients caused by non-immune factors was more than that from the infertility patients caused by RIF.Immunofluorescence staining showed the expression of endometrial related marker proteins estrogen receptor,keratin and E-cadherin,indicating the successful construction of endometrial organoids.ELISA results showed that the levels of interferon(IFN)-γ,interleukin(IL)-10,tumor necrosis factor(TNF)-α,IL-4 and TNF-α/IL-4 ratio between the 2 groups were significantly different(P＜0.05 or P＜0.01).There were no significant differences in the levels of TGF-β1 or IL-17,the ratios of IL-17/TGF-β1,IFN-γ/IL-10 or TNF-α/IL-10(all P＞0.05).Conclusion Endometrial organoids with proliferative ability from patients with non-immune infertility and RIF have been successfully cultured in vitro,which provides a new model for the basic research of immune infertility.

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 summarize the survival rate, complications, and outcomes of 32 periviable extremely preterm infants (PEPIs) born at ≤23 gestational weeks.Methods:This was a retrospective observational study involving PEPIs born at the Shenzhen Maternity & Child Healthcare Hospital from January 1, 2015, to December 31, 2021. Clinical data of all subjects were collected and analyzed. The survival rates of PEPIs born from 2015 to 2019 and 2020 to 2021 were compared. Chi-square (or Fisher's exact) test was used for statistical analysis. Results:(1) During the study period, 32 PEPIs were admitted, accounting for 0.024% (32/132 534) of all newborns born in the same hospital during the study period. The median gestational age of the 32 PEPIs was 23 weeks (21 +4-23 +6 weeks), and the birth weight was 480 g (350-720 g). (2) The survival rate of PEPIs born between 2020 and 2021 was 10/19, which appears to be a trend higher than that between 2015 and 2019 (3/13, χ2=2.79, P=0.095), while the rate of withdrawal of treatment was 8/13 and 3/19, respectively, with a statistically significant difference ( χ2=7.16, P=0.007). (3) Thirteen of the 32 PEPIs survived on discharge, including four born at 22 weeks and nine at 23 weeks. The birth weights of these surviving infants were 300-<400 g in one case, 400-<500 g in five cases, 500-<600 g in four cases, 600-<700 g in one case, and ≥700 g in two cases. (4) The most common complication was moderate and severe bronchopulmonary dysplasia (10/13), followed by retinopathy of prematurity requiring surgical intervention (5/13), patent ductus arteriosus requiring ligation (4/13), late-onset sepsis (2/13), necrotizing enterocolitis (stage Ⅱa or above) (2/13) and grade Ⅲ-Ⅳ intraventricular hemorrhage or periventricular leukomalacia (2/13). The median duration of follow-up was ten months (6-69 months), and motor retardation occurred in three infants. Conclusions:The overall survival rate of PEPIs in our hospital is relatively high, with a lower incidence of complications during hospitalization and relatively better outcome. However, further studies are required for the long-term prognosis in this group of infants.
