Objective:To compare the differences in surgical safety and postoperative cosmetic effects between endoscopic nipple-sparing mastectomy with immediate prepectoral prosthesis breast reconstruction and conventional nipple-sparing mastectomy with immediate subpectoral prosthesis breast reconstruction.Methods:The clinical data of early breast cancer patients admitted to the Department of Breast Surgery of Peking University Peoples Hospital from Oct 1, 2022 to Sep 13, 2023 was retrospectively analyzed.Results:According to the surgical method, the patients were divided into endoscopic surgery group (30 cases) and traditional surgery group (46 cases). There were no significant differences in the basic clinicopathological data, and the number of sentinel lymph nodes taken and axillary lymph nodes dissected between the patients in two groups (all P>0.05). Compared with that in traditional surgery group, the patients in endoscopic surgery group had longer operation time and more wound drainage volumes 3 days after surgery (all P<0.05). There was no significant differences in the probability of postoperative complications between the patients in two groups (all P>0.05), however, the proportion of nipple-areola complex necrosis in patients of endoscopic surgery group (10.0%) was lower than that of traditional surgery group (26.1%). Conclusions:The single-port insufflation technique-assisted endoscopic nipple-sparing mastectomy with immediate prepectoral prosthesis breast reconstruction maximize the cosmetic effect. Under the premise of strict selection of indications, it can be an optional surgical method.

Objective:To study the association of non-alcoholic fatty liver disease(NAFLD) and advanced liver fibrosis with osteoporosis in patients with type 2 diabetes mellitus(T2DM).Methods:Data was collected from 391 in-patients with type 2 diabetes mellitus(T2DM) from September 2019 to September 2020 at the Department of Endocrinology and Geriatric Medicine, Affiliated Huai′an First Hospital of Nanjing Medical University in this cross-sectional study. Participants were divided into T2DM with coexistent NAFLD(TCN) and with no NAFLD(TON) group via liver B-mode ultrasound.Also, the patients were divided into low and middle-high risk group via fibrosis index based on 4 factors index(FIB-4). Participant characteristics, laboratory results, and dual energy x-ray absorptiometry were obtained and analyzed. Multivariable logistic regression models were used to evaluate the association of NAFLD and advanced liver fibrosis with osteoporosis in T2DM. Interaction and stratified analyses were conducted according to age, sex, body mass index(BMI) and duration of diabetes(DD).Results:There was no significant difference in risk of osteoporosis and bone mineral density(BMD) loss between TCN and TON group(all P>0.05). After adjusting for age, sex, BMI, and DD, total hip BMD( β=-0.044, 95% CI -0.087--0.001, P=0.046) and lumbar L 1-L 4BMD( β=-0.044, 95% CI -0.087--0.002, P=0.044) were significantly reduced, and the risk of osteoporosis was significantly increased( OR=2.428, 95% CI 1.124-5.244, P=0.024) in FIB-4 middle-high risk group compared with low risk group. The subgroup analysis showed that overweight patients with T2DM had a significantly increased risk of osteoporosis( OR=4.240, 95% CI 1.637-10.987, interaction P=0.018) in FIB-4 middle-high risk group compared with low risk group. Conclusion:There was no significant difference in risk of osteoporosis and BMD loss between TCN and TON group. However, among T2DM patients who were overweight, NAFLD-related progressive liver fibrosis emerged as an independent risk factor for both BMD decline and the development of osteoporosis.

Recent studies have shown that the occurrence and development of common liver diseases, including non-alcoholic fatty liver disease, cirrhosis, and liver cancer, are related to liver aging(LA). Therefore, to explore the effect and mechanism of Dahuang Zhechong Pills(DHZCP), a traditional classic prescription in improving LA with multiple targets, the present study randomly divided 24 rats into a normal group, a model group, a DHZCP group, and a vitamin E(VE) group, with six rats in each group. The LA model was induced by continuous intraperitoneal injection of D-galactose(D-gal) in rats. For the LA model rats, the general situation was evaluated by aging phenotype and body weight(BW). LA was assessed by the pathological characteristics of hepatocyte senescence, hepatic function indexes, the staining characteristics of phosphorylated histone family 2A variant(γ-H2AX), and the expression levels of cell cycle arrest proteins(P21, P53, P16) and senescence-associated secretory phenotype(SASP) in the liver. The activation of the reactive oxygen species(ROS)-mediated phosphatidylinositol-3 kinase(PI3K)/protein kinase B(Akt)/forkhead box protein O4(FoxO4) signaling pathway was estimated by hepatic ROS expression feature and the protein expression levels of the key signaling molecules in the PI3K/Akt/FoxO4 signaling pathway. The results showed that after the treatment with DHZCP or VE for 12 weeks, for the DHZCP and VE groups, the characterized aging phenotype, BW, pathological characteristics of hepatocyte senescence, hepatic function indexes, relative expression of ROS in the liver, protein expression levels of key signaling molecules including p-PI3K, p-Akt, and FoxO4 in the liver, staining characteristics of γ-H2AX, and the protein expression levels of P16, P21, P53, interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α) in the liver were improved, and the effects of DHZCP and VE were similar. Based on the D-gal-induced LA model in rats, this study demonstrates that DHZCP can ameliorate LA with multiple targets in vivo, and its effects and mechanism are related to regulating the activation of the ROS-mediated PI3K/Akt/FoxO4 signaling pathway in the liver. These findings are expected to provide new pharmacological evidence for the treatment of DHZCP in aging-related liver diseases.

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.

Objective:To identify the pathogens isolated in the subperiosteal abscesses from the pediatric patients with acute osteomyelitis and to investigate the characteristics of bacterial drug resistance.Methods:A retrospective study was conducted on children with acute septic osteomyelitis who were hospitalized in the Children's Hospital, Zhejiang University School of Medicine from January 1, 2011 to March 1, 2018. The results of bacterial cultures isolated from the subperiosteal abscesses or bone marrow fluid were collected. The Merier automatic bacterial identification system (i.e., Vitek) was used to identify the bacteria and to assess the drug sensitivity.Results:(1) A total of 104 pediatric patients were included and 60 (57.7%) were male. Sixty-six strains of pathogens were isolated from 65 patients (62.5%). Among them, 53 strains (51.0%) were Staphylococcus aureus; 3 strains were Escherichia coli; 2 strains (1.9%) were Pseudomonas aeruginosa; 2 strains (1.9%) were Streptococcus pneumoniae, 2 strains (1.9%) were Ochrobactrum anthropi, and 4 strains (3.8%) were other bacteria. Pathogens were not found in 39 patients (37.5%). (2) Staphylococcus aureus accounted for 81.5% (53/65) of the pathogen-positive cases. Among them, 23 strains (43.4%) were methicillin-resistant Staphylococcus aureus (MRSA). Aureus-positive children were statistically significantly older ( P=0.028), heavier ( P=0.040) and had higher C-reactive protein (CRP) level ( P=0.038) than the aureus-negative children. (3) All the 53 Staphylococcus aureus strains were resistant to penicillin and 56.6% of them were only sensitive to benzocillin. The resistance rates to compound sulfamethoxazole, tetracycline, clindamycin and erythromycin were 11.3%, 30.2%, 67.9% and 69.8%, respectively. The sensitivity rate of the strains to furantoin was 90.2%. All strains were sensitive to quinupristin/dalfopristin, linezolid, rifampicin, tigecycline, levofloxacin, moxifloxacin, ciprofloxacin and vancomycin. There was 69.8% of the strains resistant to three or more different types of antibiotics. Conclusions:Staphylococcus aureus is the most common pathogen that causes the acute septic osteomyelitis in children, and the resistance rate to Benzocillin is relatively high. Therefore, Benzocillin and Clindamycin, as the traditionally-used drugs, should not be considered as the first choice when empirically using intravenous antibiotics. In the present study, pathogens in 39 patients (37.5%) were not detected in their subperiosteal abscesses or bone marrow fluid, so further effort should be made to investigate the etiology of these patients.

Objective:According to the requirements of high-quality development of public hospitals, to explore the innovative incentive path for medical youth based on the two-factor theory, and provide a reference for promoting the high-quality development of public hospitals.Methods:Using the literature analysis method, the two-factor theory, hospital scientific research incentive mechanism, and scientific research incentive mechanism for young talents were investigated. Meanwhile, combining the two-factor theory and practical experience, the problems that existed in the innovation incentive policy of public hospitals for young medical talents were analyzed, and the corresponding countermeasures were proposed to build the innovation incentive path of young medical talents under the two-factor theory.Results:Based on analyzing the demand characteristics of young medical talents, managers should distinguish health care factors and incentive factors, and implement incentives from both aspects. Provide incentives through improving the personal sense of achievement, creating a personal growth environment, and promoting professional titles to stimulate young talents' innovation motivation; implement health care factors from aspects of working conditions, material benefits, salary levels, etc.Conclusions:As a new concept of development, high-quality development is not only reflected in scientific and technological innovation-driven, but also in the innovation of management mechanisms so that institutional innovation becomes the driving force for high-quality development.

ObjectiveTo investigate the status and influencing factors of medication adherence in patients with severe mental disorders in Zhengzhou， so as to provide references for the formulation of prevention and treatment measures for severe mental disorders. MethodsFrom March to June 2021， a stratified multistage cluster sampling method was applied to select 342 patients from the National Information System for Severe Mental Disorders in Zhengzhou. The general demographic data of patients were collected via self-designed questionnaire， and the medication status was investigated， then the influential factors were summarized. The differences in influential factors of medication adherence were compared between the medication adherence group and the medication non-adherence group. Thereafter， Logistic regression analysis was applied to explore the factors influencing medication adherence. ResultsA total of 320 patients were included in the final analysis， altogether 76.56% of patients （n=245） complied with medication. The differences between patients in the medication adherence group and those in the medication non-adherence group were statistically significant in terms of residence， occupation， and outpatient chronic disease reimbursement （χ²=14.015， 7.502， 13.106， P<0.05 or 0.01）. In the questionnaire of influential factors on medication adherence， there were statistically significant differences in the scores of lack of insight， stigma and drug-related factors between the two groups （Z=7.588， 2.379， 2.893， P<0.05 or 0.01）. Outpatient chronic disease reimbursement was a protective factor for medication adherence （OR=2.727， 95% CI： 1.320~5.634， P<0.01）， while rural residence （OR=0.465， 95% CI： 0.221~0.977， P<0.05） and lack of insight （OR=0.398， 95% CI： 0.286~0.553， P<0.01） were risk factors for medication adherence. ConclusionPatients with severe mental disorders in Zhengzhou have a high rate of medication adherence， moreover， the outpatient chronic disease reimbursement， lack of insight and residence may be influencing factors for medication adherence in patients with severe mental disorders.
