Objective: To explore the effects of the bi-directional referral system from the perspective of the medical service consumer.Methods: A balanced panel data which was adjusted by Propensity Score Matching was employed to evaluate the effects of two-way referral system using difference-in-difference (DID) for the 2013 and 2015 data.The evaluation indicators including actual cost sharing ration, out-of-pocket cost per unit, the possibility of high cost, annual inpatient visits and length of hospital stay per unit were used.Results: Compared with the control group, the two-way referral system resulted in an 11.3% (P<0.001) increase in actual cost sharing ratio and an increase of 0.710 (P<0.001) annual inpatient visits in the intervention group.However, the policy did not significantly reduce the possibility of high-cost medical expenses and reduce the length of hospitalization and the annual cost hospitalization.Conclusion: Based on the key findings of the analysis of this study, the two-way referral system has beneficial effects on reducing inpatient financial burden and optimizing resource allocation.

Objective To evaluate the clinical effects of small-incision orbicularis-levator fixation technique for monocular double-eyelid blepharoplasty.Methods Data were collected in 56 patients (5 males and 51 females) with monocular double eyelid from January 2013 to January 2014.All patients underwent small-incision orbicularis-levator fixation blepharoplasty.To ensure the symmetry between the two eyelids,extensive study and design might be done before the surgery,including the positon of incisions,the amount of tissue removed,the tightness of sutures fixation during surgery,and so on.Results All patients were successfully operated and were performed postoperative follow-up for 19.3±3.4 months.MRI was taken on their upper eyelids preoperatively and 6 months postoperatively.Before the surgery,the MRI orbicularis oculi muscle thickness were 4.08±0.74 U in the left side and 4.81±1.05 U in the right (t=2.66,P＜0.05);the areas of orbit fat were 84.26±9.75 U2 in the left and 93.85±12.15 U2 in the right (t =3.21,P＜0.05).As for 6 months postoperatively,the MRI orbicularis oculi muscle thickness were 4.07±0.69 U in the left side and 4.37±0.99 U in the right (t=1.46,P=0.15);the areas of orbit fat were 82.88±8.81 U2 in the left and 85.30±11.94 U2 in the right (t =1.21,P=0.23).Fifty-four patients were satisfied with surgery,the eyelid's crease turned narrow in 1 case and disappeared in 1 case.Those 2 cases were adjusted by secondary surgery using the same method.Conclusions Small-incision orbicularis-levator fixation blepharoplasty has a high success rate,with acceptable bilateral symmetry and slight scar.

Long non-coding RNAs(lncRNAs)play an indispensable role in the occurrence and development of ovarian cancer(OC).However,the potential involvement of lncRNAs in the progression of OC is largely unknown.To investigate the detailed roles and mechanisms of RAD51 homolog B-antisense 1(RAD51B-AS1),a novel lncRNA in OC,reverse transcription-quantitative polymerase chain reaction(RT-qPCR)was performed to verify the expression of RAD51B-AS1.Cellular proliferation,metastasis,and apoptosis were detected using the cell counting kit-8(CCK-8),colony-formation,transwell,and flow cytometry assays.Mouse xenograft models were established for the detection of tumorigenesis.The results revealed that RAD51B-AS1 was significantly upregulated in a highly metastatic human OC cell line and OC tissues.RAD51B-AS1 significantly increased the proliferation and metastasis of OC cells and enhanced their resistance to anoikis.Biogenetics prediction analysis revealed that the only target gene of RAD51B-AS1 was RAD51B.Subsequent gene function experiments revealed that RAD51B exerts the same biological effects as RAD51B-AS1.Rescue experiments demonstrated that the malignant biological behaviors promoted by RAD51B-AS1 overexpression were partially or completely reversed by RAD51B silencing in vitro and in vivo.Thus,RAD51B-AS1 promotes the malignant biological behaviors of OC and activates the protein kinase B(Akt)/B cell lymphoma protein-2(Bcl-2)signaling pathway,and these effects may be associated with the positive regulation of RAD51B expression.RAD51B-AS1 is expected to serve as a novel molecular biomarker for the diagnosis and prediction of poor prognosis in OC,and as a potential therapeutic target for disease management.

Objective:To identify the factors associated with long-term survival and guide the decision for primary surgery in patients with advanced high-grade serous ovarian cancer(HGSOC).Methods:In this case-control study, clinical parameters, including surgical and non-surgical associated factors, were collected and compared between the patients with short-term (<2 years) and long-term (>5 years) survival who all underwent primary debulking surgery (PDS) followed by carboplatin and paclitaxel chemotherapy from January 2004 to December 2016. Univariate analysis was examined by chi-square test and multivariate analysis was performed by logistic regression analysis.Results:There were 95 cases long-term survival (LTS group) and 77 cases short-term survival (STS group) in 698 newly diagnosed HGSOC patients with International Federation of Gynecology and Obstetrics (FIGO) stage Ⅲc and Ⅳ who met include and exclude criteria. (1) Univariate analysis showed that the proportion of complete cytoreduction with no visible residual disease (R0) at PDS and platinum sensitivity in LTS group were significantly higher than those in STS group ( P<0.01). The surgical complexity score (SCS), the preoperative serum CA 125 level and the ascites volume in the LTS group were significantly lower than those of the STS group (all P<0.05). In the LTS group, the preoperative incidence of lesions in retrograde peritoneum of the bladder, serosal and mesangial membrane of the small intestine, upper abdominal peritoneum and liver parenchyma were significantly lower than those in the STS group (all P<0.05). Multivariate logistic regression analysis showed that platinum sensitivity ( OR=0.016, 95% CI: 0.004-0.063, P<0.01), ascites volume >500 ml ( OR=3.193, 95% CI: 1.285-7.930, P=0.012), and SCS ≥8 ( OR=17.433, 95% CI: 2.281-133.25, P=0.003) were independent factors affecting long-term survival ( P>0.05). (2) Totally 37 of 95 in long-term survival and 16 of 77 in short-term survival achieved R0 cytoreduction at PDS. Univariate analysis showed that preoperative serum CA 125 level, preoperative lesion score, preoperative lesion (DS) score, ascites volume, platinum sensitivity,and SCS were significantly correlated with the R0 PDS (all P<0.05). Multivariate analysis showed that ascites volume >500 ml ( OR=5.199, 95% CI: 2.015-13.409, P=0.001), DS >2 ( OR=15.264, 95% CI: 5.843-39.874, P<0.01) and SCS ≥4 ( OR=4.176, 95% CI: 1.618-10.777, P=0.003) were independent factors associated with R0 cytoreduction. In patients with DS ≤2 or SCS <4, but not those with DS >2 or SCS ≥4, R0 cytoreduction was significantly associated with long-term survival. Conclusion:The intrinsic biology of tumor is the factor influencing long-term survival of advanced HGSOC patients, and those who present with wide intraperitoneal metastases and need to remove multiple organs may not benefit from R0 cytoreduction.

Objective To analyze the characteristics of postoperative hospital-acquired infections and drug sensitivity in lung transplant recipients over the past 5 years in a single center. Methods A total of 724 lung transplant recipients at Wuxi People's Hospital from January 2019 to December 2023 were selected. Based on the principles of hospital-acquired infection diagnosis, a retrospective analysis was conducted on the hospital infection situation and infection sites of lung transplant recipients, and an analysis of the distribution of hospital-acquired infection pathogens and their antimicrobial susceptibility test status was performed. Results Among the 724 lung transplant recipients, 275 cases of hospital-acquired infection occurred, with an infection rate of 38.0%. The case-time infection rate decreased from 54.2% in 2019 to 22.8% in 2023, showing a downward trend year by year (Z=30.98, P<0.001). The main infection site was the lower respiratory tract, accounting for 73.6%. The pathogens were mainly Gram-negative bacteria, with the top four being Acinetobacter baumannii (37.1%), Pseudomonas aeruginosa (17.3%), Klebsiella pneumoniae (13.7%), and Stenotrophomonas maltophilia (13.4%), with imipenem resistance rates of 89%, 53%, 58% and 100%, respectively. Gram-positive bacteria were mainly Staphylococcus aureus (3.6%), with a methicillin resistance rate of 67%. Conclusions Over the past 5 years, the hospital-acquired infections in lung transplant recipients have shown a downward trend, mainly involving lower respiratory tract infections, with the main pathogens being Acinetobacter baumannii, Pseudomonas aeruginosa and Klebsiella pneumoniae, all of which have high resistance rates to imipenem.
