The payment methods,such as Diagnosis Related Group(DRG)for hospitalization and capitation for outpatient treat-ment,have achieved positive results in protecting the rights and interests of insured persons and improving the efficiency of the use of medical insurance funds.However,for patients with chronic diseases and rehabilitation nursing,the hospitalization period is long and the conditions complicated,and the payment method of DRGs is not reasonable.It analyzes the experiences of paying for long-term hospital cases in the US.and Germany from the aspect of reform process,payment method and regulatory measures.In order to pro-vide references for the reform of per-diem payment in rehabilitation nursing and other long-term hospitalized cases,it puts forward suggestions from aspects of realizing value care,reflecting individual differences,exploring complex payment methods,improving data quality and establishing constraint mechanism.

Objective To investigate the correlation between uterine globulin associated protein 1(UGRP1)and Fas mediated apoptosis pathway in hashimoto thyroiditis(HT).Methods The expression of UGRP1 in thyroid cells of normal people and HT patients was detected by immunohistochemistry(IHC).FRTL-5 cells were transfect-ed by plasmids in vitro,and control group,UGRP1 group,Fas group were established respectively.Real-time fluo-rescent quantitative reverse transcription PCR(RT-qPCR)was used to detect the expression of Fas and UGRP1 mRNA in each group.Results UGRP1 expression was positive in thyroid cells of HT patients and negative in that of normal people.There were no significant differences between control group and UGRP1 group in Fas gene ex-pression(1.085 0±0.124 9 vs 1.021 0±0.113 9).Compared with the control group,the expression of UGRP1 gene increased significantly in Fas group(P＜0.000 1,5.807 0±0.323 2 vs 0.752 7±0.076 0).Conclusion The high expression of UGRP1 in HT may be related to apoptosis pathway mediated by Fas.

Objective:To predict Chinese materia medica that may prevent and treat coronary microvascular dysfunction (CMD) by identifying disease core targets.Methods:CMD- related targets were obtained through GeneCards and OMIM databases. Subnetworks were extracted by using MCODE plugin in Cytoscape 3.9.1. Core targets of subnetworks were obtained by using cytoNCA plugin. GO function and KEGG pathway enrichment analysis for core targets were performed by using Metascape. Coremine Medical database was used to match targets with Chinese materia medica. Obtained Chinese materia medica was screened, and their properties and tastes, meridians and efficacy categories were under statistics.Results:Totally 3 859 disease-related targets were screened and five subnetworks were obtained. An in-depth study of MCODE1 yielded ten core targets, including IL-1β, IL6, TNF, STAT3, AKT1, ACTB, VEGFA, GAPDH, TP53, and ALB. GO functional enrichment analysis showed that these core targets were mainly involved in biological processes, such as positive regulation of gene expression, positive regulation of transcription, DNA template, and negative regulation of gene expression. KEGG pathway enrichment analysis identified 67 signaling pathways, including the AGEs-RAGE signaling pathway, HIF-1 signaling pathway, adipocytokine signaling pathway, fluid shear stress, and atherosclerosis. The researchers identified 36 kinds of Chinese materia medica associated with the ten core targets, including Salviea Miltiorrhizae Radix et Rhizoma, Chuanxiaong Rhizoma, Carthami Flos, Paeoniae Radix Rubra, Coptidis Rhizoma, Ginseng Radix et Rhizoma, Ophiopogonis Radix, Schisandrae Chinensis Fructus, Cinnamomi Cortex, Nelumbinis Semen, and Valerianae Jatamansi Rhizoma et Radix among 880 herbs.Conclusion:This study predicts 36 kinds of Chinese materia medica that have the effect of preventing and treating CMD, which can provide research ideas for the development of new drugs.

Objective:To retrospectively analyze the clinical characteristics of 193 Chinese patients with McCune-Albright syndrome (MAS).Methods:By using keywords " McCune-Albright syndrome", " Albright syndrome", or " fibrous dysplasia " as the search terms, 193 cases of MAS reported in China from January 1990 to November 2022 from the Wanfang data, CNKI, VIP, PubMed, and Embase databases were obtained, and their clinical data was retrospectively analyzed. Intergroup comparisons were carried out by using t test, Mann-Whitney U test, and χ2 test. Results:The 193 MAS patients had included 42 males and 151 females, with the median first-visit age of females being younger than males. The typical triad group had accounted for 46.1% of patients, and the middle first-visit and diagnosis age was younger than the atypical group. The primary reason for first-visit in males of MAS was fibrous dysplasia (FD), whilst that in females of MAS was peripheral precocious puberty (PPP). FD has occurred in 84.5% of the patients, with an average age of onset age being 6.1 years old, and 90% was ≤ 16 years of age. Endocrine hyperfunction was found in 79.3% of the patients, with a higher proportion in females compared with males ( P<0.05). Pituitary involvement was seen in 21.8% of the patients, and the incidence of craniofacial FD and cranial nerve compression was significantly higher in those with elevated growth hormone (GH) than without ( P<0.05). Café-au-Lait Spots were noted in 86.5% of the patients, and 28.3% (28/99) had located on the different side of FD. Conclusion:Most MAS patients had atypical manifestations and multi-systemic involvement. It is more common and occurs earlier in females. The most common reasons for initial diagnosis in male and female patients were FD and PPP, respectively. Patients with elevated GH should be examined for cranial nerve compression.

Objective:To investigate the clinical characteristics and management status of children with Turner syndrome (TS) in China.Methods:As a cross-sectional study, 1 089 TS patients were included in the database of the National Collaborative Alliance for the Diagnosis and Treatment of Turner Syndrome from August 2019 to November 2023. Clinical characteristics (growth development, sexual development, organ anomalies, etc.), karyotypes, auxiliary examinations, and treatments were collected and analyzed.Results:Among the 1 089 TS cases, 809 were recorded karyotypes. The karyotype distribution was as follows: 45, X in 317 cases (39.2%), X chromosome structural variants (including partial deletions of p or q arm, ring chromosome, and marker chromosome) in 89 cases (11.0%), 45, X/46, XX mosaicism in 158 cases (19.5%), mosaicism with X chromosome structural variants in 209 cases (25.8%), and presence of Y chromosome material in 36 cases (4.4%). Among the 824 TS cases, the age of diagnosis was 9.7(6.4, 12.2) years, with a height standard deviation score (HtSDS) of -3.1±1.2. Five hundred and fifty three cases underwent growth hormone (GH) stimulation test, and 352 cases (63.7%) had GH peak values <10 μg/L and 75.9% (577/760) had low IGF1 levels, with IGF1 SDS ≤-2 accounting for 38.2% (290 cases). Among 471 cases aged ≥8 years, 132 cases (28.0%) showed spontaneous sexual development (mean bone age (11.0±1.7) years), 10 cases had spontaneous menarche (mean bone age (12.0±2.2) years), and 2 cases had regular menstrual cycles. Common physical features included cubitus valgus (311 cases (28.5%)), neck webbing (188 cases (17.2%)), low posterior hairline (185 cases (17.0%)), shield chest (153 cases (14.0%)), high arched palate (127 cases (11.6%)), short fourth metacarpal (43 cases (3.9%)), and spinal abnormalities (38 cases (3.5%)). Congenital cardiovascular and urogenital anomalies occurred in 91 cases (19.4%) and 66 cases (12.0%)respectively. Abdominal ultrasound in 33 cases (7.2%) indicated fatty liver, hepatomegaly, intrahepatic bile duct stones, and splenomegaly. Among 23 cases undergoing oral glucose tolerance test (OGTT) test, 2 were diagnosed with diabetes mellitus and 4 with impaired glucose tolerance. Following diagnosis, 669 cases (80.7%) received rhGH treatment at a chronological age of (9±4) years and bone age of (8.3±3.2) years. Additionally, 112 cases (19.4%) received sex hormone replacement therapy starting at the age of (14±4) years and bone age of (12.6±1.2) years.Conclusions:The karyotypes of 45, X and mosaicism were most common in Chinese children with TS. The clinical manifestations were mainly short stature and gonadal dysplasia. However, a few TS children could be in the normal range of height, and some cases among those aged of ≥8 years old had spontaneous sexual development. Some exhibited physical features, congenital cardiovascular and urogenital anomalies, and dysfunction of the hypothalamic-pituitary-IGF1 axis. Moreover, a few of them developed impaired glucose tolerance and diabetes mellitus. Following diagnosis, most of the patients received rhGH treatment, and a few of them received sex hormone replacement therapy.

In November 2023, the seventh National Nucleic Acid Vaccine Conference was held to deeply discuss the immune mechanism, safety risks, advantages, and disadvantages of nucleic acid vaccines, and review the safety and effectiveness of COVID-19 vaccines developed by nucleic acid vaccine technology. Some prospectives were formed in the meeting that in the post-pandemic era, nucleic acid vaccine technology will play a role in the following areas: dealing with pathogens that are difficult to be prevented by traditional vaccines, promoting the upgrading of traditional live attenuated vaccines, contributing to the development of multivalent and combined vaccines, and rapid response to emerging and re-emerging infectious diseases. These views point out the direction for the future development of nucleic acid vaccine technology.

Osteosarcoma is the most common primary malignant bone tumor in children and adolescents. With the emergence of chemotherapy resistance in recent years, the survival rate of osteosarcoma patients has reached a bottleneck. Therefore, exploration of its chemoresistance mechanism is one of the popular research directions currently. Non-coding RNA (ncRNA) is a class of RNA without the ability to encode proteins, which is classified into microRNA, long non-coding RNA, and circular RNA based on length and shape. With the development of high-throughput sequencing technology, there is increasing evidence that some non-coding RNAs are abnormally upregulated or downregulated in osteosarcoma cells and affect the response of osteosarcoma to four commonly used chemotherapeutic drugs (methotrexate, doxorubicin, cisplatin and ifosfamide) through mechanisms such as regulation of apoptosis, cell cycle, signaling pathways, intracellular drug concentration, and cellular autophagy. Therefore, thesenon-coding RNAs are expected to be novel targets for osteosarcoma treatment. In this paper, the current studies were searched and reviewed on the above three non-coding RNAs mediating chemoresistance in osteosarcoma, aiming to provide a reference for breaking the bottleneck of survival rate of osteosarcoma patients.

The National Medical Products Administration has authorized sodium oligomannate for treating mild-to-moderate Alzheimer's disease.In this study,an LC-MS/MS method was developed and validated to quantitate sodium oligomannate in different biomatrices.The plasma pharmacokinetics,tissue distri-bution,and excretion of sodium oligomannate in Sprague-Dawley rats and beagle dogs were system-atically investigated.Despite its complicated structural composition,the absorption,distribution,metabolism,and excretion profiles of the oligosaccharides in sodium oligomannate of different sizes and terminal derivatives were indiscriminate.Sodium oligomannate mainly crossed the gastrointestinal epithelium through paracellular transport following oral administration,with very low oral bioavail-ability in rats(0.6％-1.6％)and dogs(4.5％-9.3％).Absorbed sodium oligomannate mainly resided in circulating body fluids in free form with minimal distribution into erythrocytes and major tissues.So-dium oligomannate could penetrate the blood-cerebrospinal fluid(CSF)barrier of rats,showing a con-stant area under the concentration-time curve ratio(CSF/plasma)of approximately 5％.The cumulative urinary excretion of sodium oligomannate was commensurate with its oral bioavailability,supporting that excretion was predominantly renal,whereas no obvious biliary secretion was observed following a single oral dose to bile duct-cannulated rats.Moreover,only 33.7％(male)and 26.3％(female)of the oral dose were recovered in the rat excreta within 96 h following a single oral administration,suggesting that the intestinal flora may have ingested a portion of unabsorbed sodium oligomannate as a nutrient.

Objective:To compare the clinical value of contrast-enhanced ultrasound (CEUS) - and CT-guided percutaneous puncture biopsy in the diagnosis of peripheral lung masses.Methods:The clinical data of 90 patients with peripheral lung masses who underwent puncture biopsy in Tumor Hospital Affiliated to Nantong University from October 2019 to December 2021 were retrospectively analyzed. According to different puncture guidance methods, patients were divided into CEUS-guided percutaneous puncture biopsy group (CEUS group, n=40) and the CT-guided percutaneous puncture biopsy group (CT group, n=50) , and the differences in puncture success rates, complication rates and other factors between the two groups were evaluated. Meanwhile, the correlations between microvascular density (MVD) and CEUS parameters were detected. Results:The puncture success rate in the CEUS group was higher than that in the CT group, but there was no statistically significant difference [97.5% (39/40) vs. 92.0% (46/50) , P=0.337], and the complication rate in the CEUS group was significantly lower than that in the CT group [0 (0/40) vs. 12.0% (6/50) , P=0.032]. Compared with the CT group, the CEUS group has fewer punctures [ (2.0±1.6) times vs. (2.8±1.2) times, t=-2.43, P=0.018], shorter duration [ (7.6±2.5) min vs. (15.3±2.6) min, t=-8.86, P<0.001] and lower cost of surgery [ (1 308.4±545.6) yuan vs. (2 046.4±645.3) yuan, t=-2.01, P=0.046]. The MVD, CEUS peak intensity and enhancement index of lung adenocarcinoma were higher than those of squamous cell carcinoma [ (25.4±4.9) /HP) vs. (16.6±7.3) /HP, t=3.43, P=0.002; (46.9±6.5) db vs. (36.8±5.4) db, t=4.12, P<0.001; 5.2±1.4 vs. 4.1±1.2, t=3.27, P=0.006]. The peak intensity and intensity index of CEUS in lung adenocarcinoma or squamous cell carcinoma were positively correlated with itself MVD (squamous cell carcinoma: r=0.66, P<0.001; r=0.56, P<0.001; adenocarcinoma: r=0.62, P<0.001; r=0.70, P<0.001) . Conclusion:Although CEUS-guided percutaneous puncture biopsy does not achieve a higher puncture success rate in the diagnosis of peripheral lung masses compared to CT, it really decreases the complication rate, and has the advantages of less time, low cost, no radiation and real-time dynamic monitoring, which is worth promoting in clinic. Moreover, there are correlations between CEUS quantitative parameters of adenocarcinoma and squamous cell carcinoma of the lung and MVD, which may be useful for diagnosis.

Turner syndrome(TS)results from a sex-chromosomal anomaly characterized by presence of one normal X chromosome and the loss of the second X-chromosome in phenotypic females.The typical clinical manifestations of Turner syndrome are short stature, hypogonadal dysplasia, and special physical characteristics(such as neck web, shield chest, elbow valgus, etc.). And it is related to the risk of autoimmune diseases, such as autoimmune thyroiditis, celiac disease, type 1 diabetes, inflammatory bowel disease, alopecia areata or vitiligo.This review will address the autoimmune disorders associated with TS, their pathophysiologic mechanisms and clinical characteristics.
