Objective To explore the efficacy of an 11-item modified frailty index(mFI-11)combined with surgical Apgar score(SAS)for predicting postoperative complications in elderly patients with colorectal cancer undergoing laparoscopic radical resection.Methods We enrolled a total of 481 elderly patients(aged≥65 years)undergoing laparoscopic radical resection of colorectal cancer.We performed a frailty assessment preoperatively using mFI-11 and calculated the SAS based on the lowest mean arterial pressure and heart rate as well as blood loss during surgery.Finally,we compared the clinical data,mFI-11,and SAS of patients with and without post-operative complications,and then analyzed their relationship with the postoperative complications and predictive values.Results The mFI-11,SAS,and operation time independently correlated with postoperative complication occurrence(P<0.05).The AUC of post-operative complications obtained using the mFI-11,SAS,and operation time were 0.805,0.800,and 0.610,respectively.The AUC of the postoperative complications derived from mFI-11 combined with SAS was 0.902.Conclusion In elderly patients undergoing laparo-scopic radical resection of colorectal cancer,the mFI-11,SAS,and operation time significantly correlated with postoperative complication occurrence.The combination of mFI-11 and SAS displayed a higher predictive power for postoperative complications compared to the use of a single indicator,which it could provide a reliable basis for early clinical identification of complications and reduce their occurrence.

Objective To summarize the exploration and current situation of pharmaceutical service fees in China,to analyze it in conjunction with practices in foreign countries,and to provide references for further improvement of pharmaceutical service fees in China.Methods The official websites of the National Health Commissi,National Healthcare Security Administration,and their provincial braches were retrieved to summarize the changes in policies in China and the latest pharmaceutical service fees policies in each province.At the same time,databases such as CNKI,VIP,and Pubmed were searched to summarize research on pharmaceutical service fees.Results There were some studies in China on the calculation of pharmaceutical service costs and fee standards,but they mostly focused on pharmacy dispensing services,with less discussion on the technical and labor value of specific pharmaceutical services,while international research in this area was relatively abundant.Currently,eight provinces and one municipality directly under the central government have issued medical service price items related to pharmaceutical service,with differences in fee items,fee standards,medical insurance payment ratios,and monitoring and evaluation indicators.Conclusions The inclusion of pharmaceutical services in the national medical pricing system recognizes the transformation of pharmaceutical services and the value of pharmacists.However,it is still in the early stages,and there is room for improvement and enhancement.

Objective:To compare the social support levels as understood by family doctor team members in township hospitals/community health centers, and village clinics/community clinics, and their influencing factors, in order to provide reference for improving the work status of family doctor team members and enhancing the quality of family doctors′ contracted services.Methods:A multi-stage random cluster sampling method was used to sample medical workers from contracted family doctor teams in township hospitals/community health centers and their subordinate village clinics/community clinics in 6 counties (cities, districts) of Tai′an city, Shandong province. In August 2020, a questionnaire survey was conducted on the perceived level of social support among family doctor team members using the perceived social support scale. Descriptive analysis was conducted on the data, and independent sample t-tests and one-way ANOVA were used to conduct univariate analysis on the influencing factors of perceived social support scores of family doctor team members at different levels, while multiple linear regression analysis was used to conduct multivariate analysis. Results:A total of 765 valid questionnaires were collected, with 203 and 562 from township hospitals/community health centers and village clinics/community clinics, respectively. The total perceived social support scores of family doctor team members in township hospitals/community health centers and village clinics/community clinics were (65.56±10.29) and (67.31±10.14), respectively, featuring statistically significant differences ( t=-2.11, P<0.05). In-mirage marital status ( β=0.18, P=0.008), good/very good self-rated health status ( β= 0.25, P=0.048), participation of work-related training within one year ( β=0.17, P=0.010), relatively satisfied/very satisfied for job promotion ( β= 0.17, P=0.046), as well as above/far above average self-rated economic status as ( β=-0.15, P=0.027), were the influencing factor on the perceived social support scores of family doctor team members in township hospitals/community health centers. In-marriage marital status ( β= 0.12, P=0.002), good/very good self-rated health status ( β=0.14, P=0.026), junior or intermediate level or above professional title ( β=-0.11, P=0.003; β=-0.10, P=0.006), participation of work-related training within one year ( β= 0.14, P<0.001), and relatively satisfied/very satisfied for job promotion ( β= 0.16, P<0.001) were the influencing factors on the perceived social support scores of family doctor team members in village clinics/community clinics. Conclusions:Members of the family doctor teams in primary medical institutions in Tai′an city had a higher level of understanding of social support. There were differences in the social support levels of family doctor team members between the two levels of primary medical and health care institutions, and the influencing factors were not completely consistent. Targeted measures should be taken based on specific circumstances to enable them to better receive and perceive support from family and friends, and to improve the quality of family doctors′ contracted services.

Objective: To investigate the histological features and prognostic factors of angioimmunoblastic T-cell lymphoma (AITL). Methods: The pathological data of 62 patients with AITL with complete follow-up information were retrospectively collected and analyzed from Changhai Hospital during September 2012 and September 2017. Histological and immunohistochemical (IHC) examination, in situ hybridization (ISH), and single nucleotide polymorphisms (SNP) gene mutation analysis were done. Subgroup evaluation with histology, IHC, ISH, SNP gene mutation, and association with clinical progression were performed. Results: The cohort included 62 cases of AITL, including 46 males and 16 females patients, with a median age of 64 years. Follicular dendritic cells (FDC) area showed significantly expansion (≥30%) in 40 cases; increased plasma cells (≥10%) was seen in 37 cases; B cells were distributed around blood vessels in 37 cases; and increased p53 mutation positive cells (≥40%) were seen in 39 cases; high Ki-67 index (≥40%) was seen in 39 cases; RHOA mutation was seen in 19 cases; TET2 mutation was seen in 9 cases. Overall survival analysis showed these factors were significantly correlated with tumor prognosis (P<0.05). Multivariate analysis showed that CD38 positive cells<10%, Ki-67≥40%, RHOA and TET2 mutations were risk factors associated with overall survival. Conclusions AITL could be divided into two different prognostic groups, low-grade and high-grade, with statistically significance outcome, based on the FDC area expansion, degree of plasma cell proliferation, B cells distribution pattern combined with gene mutations and clinical progression. Low-grade malignant group progresses slowly, and high-grade malignant group is highly invasive.

Objective To evaluate the etiology,epidemiological characteristics,clinical diagnosis,and outcomes of hospitalized patients with AKI in Xinjiang,analyzing the risk factors of their clinical prognosis.Methods A multicenter retrospective survey was conducted,investigating adult patients admitted to four hospitals in Xinjiang in January and July 2013.Patients with AKI were screened out based on KDIGO's inclusion and exclusion criteria.Clinical variables of patients with AKI including demographics,clinical data,laboratory tests,treatment measures and prognosis were collected.Results Among 32,157 adult hospitalized patients,there were 722 AKI patients.Excluding those with incomplete data,719 patients were enrolled in this study.The detection rate of AKI was 2.25％ (722 of 32,157) by KDIGO criteria.The main cause for AKI was pre-renal injury,led mainly by cardiac output,low blood volume,and the use of nephrotoxic drugs.The non-recognition rate of AKI was 72.4％ (407/557).Multivariate binary logistic regression analysis showed that AKI stage,peripheral vasodilation and renal parenchyma were protective factors of the omission diagnosis.In the short-term prognostic analysis,the overall mortality rate was 12.8％(92/719).Among the 323 patients with AKI who survived discharge,43.7％(141) had renal function recovery;40.2％(130) did not fully recover their renal function but ceased maintenance dialysis;16.4％ (53) were still on dialysis at discharge.Multivariate Cox regression model suggested that DIC,shock and department of obstetrics were independent risk factors for death during hospitalization of AKI.In addition,the risk of death for AKI from department of obstetrics and gynecology patients was higher than that of other departments.Conclusions The most common reason for AKI in hospitalized patients in Xinjiang was pre-renal injury.The main risk factors were low cardiac output and low blood volume.The omission diagnosis of AKI was serious;AKI stage,peripheral vasodilation and renal parenchymal injury however were its protective factors.Poor-DIC,shock,hospitalization in obstetrics were independent risk factors for death in patients with AKI.

[Abstract] Objective: To search valuable candidate molecular markers for LSCC by screening and identifying differentially expressed long non-coding RNAs (lncRNAs) in metastatic laryngeal squamous cell carcinoma (LSCC) with high throughput gene microarray technique. Methods: Four pairs of LSCC tissues and corresponding para-cancer tissues that pathologically confirmed with lymph node metastasis were collected from Bio-sample lab of Otorhinolaryngology Department, the Second Hospital of Hebei Medical University. After total RNA extraction, the SBC-lncRNA (human 4x180k) chip assay was then applied to detect the differentially expressed lncRNAs and mRNAs, and Fold-change and Student's t-test methods were used to identify differentially expressed genes; the Fold Change (linear)≤0.5 or≥2.0, P<0.05 was used to identify the differentially expressed genes. The reliability of the chip results was confirmed by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Results: The gene expression profiles of metastatic LSCC tissues and corresponding para-cancer tissues were significantly different. There were 3 073 differentially expressed lncRNAs, including 1 967 up-regulated and 1 106 down-regulated lncRNAs in cancer tissues. There were 2 809 differentially expressed mRNAs, including 1 791 up-regulated and 1 018 down-regulated mRNAs in cancer tissues. The differentially expressed lncRNAs were mainly involved in cell proliferation and apoptosis, immune response biological process, and were associated with cytokine and cytokine receptor interaction, chemokine signaling pathway, cell cycle regulation, P53 signaling pathway, etc. In addition, 10 significantly differentially expressed lncRNAs were chosen and validated by qRT-PCR in 25 cases of LSCC tissues, and the results were in agree with microarray detection. Conclusions: There were obvious differences in lncRNAs expression between metastasis LSCC and corresponding para-cancer tissues; in-depth analysis of these differences may has important significance on clarifying the mechanisms of invasion and metastasis of LSCC, which can provide the theoretical basis for biomarker screening and effective targeted therapy for LSCC.·

Subthalamic nucleus (STN) deep brain stimulation (DBS) has become an important surgical treatment of Parkinson disease, but its exact mechanism is still unclear.In this study, a 16-channel implantable microelectrode array (MEA) was prepared by micro-electromechanical system (MEMS) technique and later modified with platinum black/reduced Graphene Oxide/Nafion (Pt/RGO/Nafion) nanocomposites.Extracellular dopamine (DA) content and spike of dorsal striatum neurons were synchronously recorded before and after STN stimulation.The results showed that the dopamine content began to increase within 20 s after electrical stimulation and dropped to normal level after about 50 s, with the highest rising concentration of 1.72 μmol/L.At the same time, there was an increased spike activity of interneurons in the dopamine ascending phase, and the spike firing rate of medium spiny projection neurons (MSNs) was high when the concentration of DA was higher than the normal level.The MEA sensor can simultaneously record dopamine flux and physiological signals in situ, thus providing an ideal tool for neural information detection.
