Objective:To investigate the type and severity of skin adverse reactions induced by afatinib in the treatment of lung cancer, and to analyze their correlation with anti-lung cancer efficacy.Methods:A case-case-control study was conducted on lung cancer patients treated with afatinib in ZhongDa Hospital, Southeast University from December 2016 to January 2018. The type and severity of skin adverse reactions were evaluated in 76 patients with lung cancer based on the National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 4.0, and these patients were divided into 3 groups according to the severity of skin lesions, including grade-0, -1, and -2/3 groups. The patients underwent chest computed tomography (CT) examination every 3 months, and the tumor response to afatinib was evaluated according to the Response Evaluation Criteria in Solid Tumors (RECIST) . Anti-lung cancer efficacy of afatinib was compared among the patients with different grades of skin lesions by using the Kruskal-wallis H rank sum test. Results:After treatment with afatinib, 44 of the 76 patients with lung cancer achieved stable condition or partial remission, and 32 experienced disease progression. Skin adverse reactions occurred in 69 patients, and manifested as acneiform lesions in 42 (55.3%) patients, paronychia in 35 (46.1%) , mucosal erosions in 30 (39%) , hair changes in 8 (10.5%) , and hand-foot syndrome in 6 (7.9%) . Improvement was achieved in 3, 7 and 34 cases in the grade-0, -1, and -2/3 groups ( n = 7, 19 and 50 respectively) , respectively. There was a significant difference in the response rate among the 3 groups ( χ2 = 6.117, P = 0.047) , and the response rate was significantly higher in the grade-1 and -2/3 groups than in the grade-0 group (both P < 0.001) , and higher in the grade-2/3 group than in the grade-1 group ( P < 0.001) . Conclusion:The treatment of lung cancer with afatinib can cause various types of skin lesions, such as acneiform lesions, paronychia, mucosal erosions, hair changes and hand-foot syndrome, and the higher the severity of the skin lesions, the more marked the anti-lung cancer efficacy of afatinib.

Objective:To screen the optimal process of ambi-extracting of Xinyi Powder and inclusion of volatile oil.Methods:Single factor experiment was used to optimize the extraction process of Xinyi Powder by taking crushing particle size, extraction times, the amount of water added and extraction time as the investigation factors. L 9(3 4) orthogonal test was used to optimize the inclusion process of volatile oil in Xinyi Powder. Results:The optimal extraction process of ambi-extracting of Xinyi Powder was as follows: the slices were not crushed, 10 times the amount of water was added, and extracted for 3 hours; the best inclusion process of volatile oil as follows: β-cyclodextrin:water=1:25, β-cyclodextrin:volatile oil=6:1, inclusion temperature 35 ℃, inclusion time 3 hours.Conclusion:The ambi-extracting process and volatile oil inclusion process are simple, stable and feasible.

BACKGROUND:There are many postmenopausal women taking hormone, which leads to much loss of bone mass, further inducing fragility fractures. The studies on the hormone exposure combined with ovariectomy-induced osteoporotic model are still immature, and the related molecular mechanism remains unclear. OBJECTIVE: To establish the rat osteoporotic model induced by ovariectomy combined with glucocorticoid exposure and to explore the underlying molecular mechanism. METHODS: Thirty 3-month-old female Sprague-Dawley rats were randomly divided into blank control, sham and model groups (n=10 per group). The rats in the blank control group received no intervention; rats in the sham group were clipped off a little of coeliac adipose tissue; the model rats received bilateral ovariectomy and 4-week administration of glucocorticoid. RESULTS AND CONCLUSION:At 4 weeks after modeling, compared with blank control and sham groups, the model group showed significantly lower bone mineral density of the femur, number of bone trabeculae and bone volume/total volume, and significantly wider bone trabecular spacing. Additionally, the model group revealed the damaged bone trabecular structure and thiner cortical bone. The expression level of Runx2 was downregulated whereas both collagen type 1α1 and peroxisome proliferators activated receptor γ mRNA were upregulated in the model group. These findings suggest that ovariectomized rats exposed to glucocorticoid rapidly develop femur osteoporosis, maybe by downregulating the expression of Runx2, as well as upregualting collagen type 1α1 and peroxisome proliferators activatedreceptor γ mRNA.

Objective:The present study was aimed to evaluate the nutritional risk using nutritional risk screening 2002 (NRS2002) score and to investigate the impact of nutrition support on clinical outcome in hospitalized patients.Methods:Six hundred and ninety four hospitalized patients were recruited.NRS 2002 was applied to evaluate the nutritional risk of patients.Meanwhile,the effect of nutrition support on complication rate was evaluated between different types of patients.Results:14.0％ of patients had malnutrition and the incidence of nutritional risk was 27.5％.Patients with nutritional risk had a higher complication rate (P ＜0.01).Totally,22.0％ (153/694) patients received nutrition support,including 81.7％ patients with nutritional risk and 18.3％ patients without nutritional risk.Patients with nutritional risk benefited from nutrition support,as shown by lower complication rate and shorter length of hospital stay.In patients with nutritional risk,complication rate was lower in enteral fed patients compared to parenteral fed patients.Conclusion:With nutritional risk screening,patients' nutritional status can be evaluated and appropriate nutrition support can be performed.Compared to those without nutritional risk,patients with nutritional risk will benefit more from nutrition support,as indicated by lower complication rate and reduced length of hospital stay.

Purpose: Intestinal Behcet’s disease (BD) is a systemic autoimmune disease for which treatment options are limited. As a prospective therapeutic strategy for intestinal BD, anti-tumor necrosis factor-alpha (anti-TNF-α) agents have received increasing attention. In this study, we conducted a systematic review and meta-analysis to evaluate the efficacy and safety of anti-TNF-α agents for patients with intestinal BD. Materials and Methods: We searched PubMed, Embase, and Cochrane Library databases up to July 1, 2021 and articles that met the eligibility criteria were further assessed. Pooled rates were synthesized by a randomized effects model using Stata software. Results: Eleven clinical trials covering 671 patients with intestinal BD were included. According to compositive data, the pooled rate for remission was 39% [95% confidence interval (CI) 26–52] in patients receiving anti-TNF-α agents. Intestinal symptoms were cured in 70% (95% CI 53–84) of the patients, and the rate for endoscopic healing was 65% (95% CI 52–78). Corticosteroid discontinuation was achieved in 43% (95% CI 28–58) of the patients, and the dose reduction of corticosteroid was 20.43 mg (95% CI 13.4–27.46). There were 239 adverse events and 80 serious adverse events during follow-up. Conclusion Our study indicated that anti-TNF-α agents may serve as an effective treatment with acceptable safety for patients with intestinal BD. However, more robust evidence from randomized controlled trials is urgently needed to assess the long-term efficacy and safety of anti-TNF-α agents for those patients.

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 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.

Objective:To explore the different types and characteristics of rehabilitation exercise compliance of patients with first stroke at 2 weeks of onset, and analyze its influencing factors, so as to provide reference for the formulation of targeted health education.Methods:A cross-sectional investigation was conducted in Neurology Department of the Second Affiliated Hospital of Zhejiang University School of Medicine from January to June, 2021. 276 patients with first-episode stroke were investigated by the Questionnaire of Exercise Adherence at 2 weeks of the onset. The potential profile analysis was conducted to explore characteristics classification of the rehabilitation exercise compliance. And the chi-square test was used to compare demographic differences among different categories and ordered multi classification Logistic regression was used to explore the influencing factors of rehabilitation exercise compliance.Results:The patients were divided into 109 cases with high rehabilitation exercise compliance (39.5%), 114 cases with moderate rehabilitation exercise compliance (41.3%), and 53 cases with low rehabilitation exercise compliance (19.2%). There were statistically significant differences in education level, consciousness level at admission, complications and limb muscle strength among the three types of patients ( χ2 values were 6.17-31.50, all P<0.05). Ordered multi classification Logistic regression showed that the patient′s education level, the patient′s consciousness level at admission, whether there were complications and limb muscle strength would affect the rehabilitation exercise compliance of stroke patients ( P<0.05). Conclusions:There are three potential categories of rehabilitation exercise compliance in patients with first stroke. Patients with illiteracy, drowsiness, complications and poor limb muscle strength have poor rehabilitation exercise compliance.

Objective To explore the relationship between serum iron(SI)metabolism and glucose and lipid metabolism in patients with type 2 diabetes mellitus(T2DM).Methods A total of 170 T2DM patients hospitalized in the Department of Endocrinology,Lanzhou University First Hospital from 2019 to 2021 were included.During the same period,30 healthy individuals from physical examination center were selected as the normal control(NC)group.Based on HbA1c control,T2DM patients were divided into subgroups with good blood glucose control(H1,HbA1c＜7%,n=39),poor glucose control(H2,7%＜HbA1c＜9%,n=63)and very poor glucose control(H3,HbA1c＞9%,n=68).According to the level of blood lipids,T2DM patients were divided into subgroups with normal blood lipids(L1,n=36)and high blood lipids(L2,n=134).Results Compared with NC group,age,SBP,DBP,BMI,serum ferritin(SF),FPG,FIns,HOMA-IR,TyG,TG,LDL-C and SUA increased inT2DM group(P＜0.05),while SI,TF,total iron binding capacity(TIBC),DI,HDL-C and eGFR decreased(P＜0.05).The levels of TF and TIBC in H3 subgroup were lower than those in H1 subgroup(P＜0.05).LDL-C of L2 subgroup was higher than that of L1 subgroup(P＜0.05),while HDL-C was lower than that of L1 subgroup(P＜0.05).Pearson correlation analysis showed that SF was positively correlated with HbA1c,TyG,TG and SUA(P＜0.05),and negatively correlated with HDL-C and eGFR(P＜0.05).TF was positively correlated with HDL-C and eGFR(P＜0.05),but negatively correlated with age,SBP,DBP,TyG and SUA(P＜0.05).Multiple linear regression analysis showed that SF and FPG were influencing factors for HbA1c in T2DM patients.Conclusion SI metabolism is closely related to glucose and lipid metabolism in T2DM patients.
