OBJECTIVE To investigate the actual construction and operation status of established and under-construction centralized （cloud） prescription review centers （shortened for “prescription review center”） of close-knit county-level medical consortium in a certain city， so as to provide reference for improving the construction quality of the prescription review center. METHODS An online questionnaire survey was conducted to collect the data from 51 established and under-construction prescription review center in the city， covering basic information， funding sources， talent management， system construction， review rule maintenance， prescription review practices， prescription evaluation， data utilization， and current challenges. The collected data were summarized and analyzed. RESULTS A total of 51 valid questionnaires were retrieved， covering 32 established and 19 under-construction prescription review center. Among the 32 established prescription review centers， the main funding sources for their construction came from government financial allocations， accounting for 56.25%. Only 25.00% of prescription review center had review pharmacists who fully met national qualification requirements， and just 55.00% updated more than 10 review rule entries per month on average. Outpatient prescription verification realized full coverage， but 37.50% of prescription review centers only supported rationality verification of single prescriptions， and 50.00% could not retrieve laboratory and examination results to assist in prescription review. Additionally， 40.62% of prescription review center had not regularly conducted prescription evaluations for primary care institutions. The data from prescription review center was mainly used to support medication monitoring. Among the 19 prescription review centers currently in the planning stage， 63.16% had no identified funding sources. CONCLUSIONS The operation and construction of prescription review center in the city face challenges， such as funding shortages， absence of collaborative incentive mechanisms， and insufficient manpower.It is suggested that the state should issue a unified standard for the construction of the prescription review center as soon as possible， and local health administrative departments should formulate supporting policies and clarify assessment indicators in combination with the actual situation of the region.

Objective:To investigate the independent risk factors of recurrent laryngeal nerve(RLN)injury after microwave ablation(MWA)for thyroid nodules of different malignant stratification.Methods:The medical records of 240 patients,who underwent microwave ablation for thyroid nodules in the department of ultrasound,Beijing Friendship Hospital Affiliated to Capital Medical University from September 2022 to August 2024,were retrospectively selected.All thyroid nodule cases were categorized based on the American College of Radiology Thyroid Imaging Reporting and Data System(TI-RADS)classification criteria and whether occurred RLN injury during the ablation procedure.A total of 54 patients with RLN injury and 65 patients without RLN injury,who were classified as TI-RADS 4a or higher than that,were divided into the high-risk group,and 35 patients with RLN injury and 86 patients without RLN injury,who were classified below TI-RADS 4a,were divided into the low-risk group.And then,a series of parameters included the benign and malignant nodules,the upper diameter of nodules,the left and right diameters of nodules,anteroposterior diameters of nodules,the aspect ratio(>1,≤1),overall echo,calcification,location,cystic solidity,and ablation parameters were analyzed.The risk factors of RLN injury of two groups were analyzed by using single factor and multi factor analysis.Results:There were not significant differences in the benign and malignant nodules,the upper diameters of nodules,the left and right diameters of nodules,anteroposterior diameters of nodules,the volume of nodules,overall echo,calcification,ldiametersocation,and cystic solidity between high and low-risk groups(P>0.05).In high-risk group,the distance between nodules and esophageal groove of trachea was less or equal to 2mm,and the increase of nodule volume were independent risk factors for RLN injury(OR=4.199,1.002,P<0.05),respectively.In the low-risk group,the nodule,which location was on the Zuckerkandl tubercle(Z-nodule),was risk factor that significantly increased RLN injury(OR=3.296,P<0.05).Conclusion:For nodules with differently malignant risk,the anatomical location,volume parameters and optimized ablation plan should be paid special attention before surgery,so as to reduce the risk of RLN injury.

Objective:To investigate the characteristics and clinical effects of laparoscopic pneumovesical Cohen and laparoscopic Lich-Gregoir ureteral replantations for the treatment of primary obstructive megaloureter (POM) in children.Methods:A randomized controlled study was conducted.The clinical data of 51 children with unilateral POM admitted to the First Affiliated Hospital of Zhengzhou University from October 2018 to October 2023 were collected.Random number table method was used in the selection of surgical methods.They were divided into the laparoscopic pneumovesical Cohen ureteral replantation group (group A, 22 cases) and the laparoscopic Lich-Gregoir ureteral replantation group (group B, 29 cases) according to the surgical method.The anterior-posterior diameter(APD), maximum ureteral diameter and differential renal function parameters on the affected side were measured by color Doppler ultrasound of the urinary system, and compared between and within the two groups before and after surgery.The operation time, blood loss and postoperative intubation time were compared between the two groups.The incidence of postoperative complications such as reflux, bladder spasm, urinary retention and urinary tract infection was recorded.The independent and paired sample t-tests were used for statistical analysis. Results:The operation time and hematuria duration of group B [(125.7±14.2) min, (1.5±0.6) d] were significantly shorter than those of group A [(142.6±14.7) min, (2.8±0.7) d] (all P<0.05). The APD, maximum ureteral diameter, and differential renal function on the affected side of group A were (21.7±7.9) mm, (11.6±3.2) mm, and (28.2±4.9)% before surgery, and (10.3±4.5) mm, (6.0±2.0) mm and (43.8±4.4)% after surgery, respectively.The APD, maximum ureteral diameter, and differential renal function on the affected side of group B were (21.1±5.6) mm, (11.3±4.6) mm, and (30.2±5.5)% before surgery, and (10.2±4.5) mm, (6.6±2.0) mm, and (42.4±5.2)% after surgery, respectively.There was no statistically significant difference in the values of APD, maximum ureteral diameter, and differential renal function before and after surgery between the two groups of children (all P>0.05). However, there were statistically significant differences in the values of APD, maximum ureteral diameter, and differential renal function before and after surgery between the same group of children (all P<0.01). No significant difference was found in intraoperative blood loss, postoperative intubation time, and postoperative complications between the two groups (all P>0.05). Conclusions:Both surgical methods are effective in the treatment of POM in children.Laparoscopic Lich-Gregoir ureteral replantation has advantages of less operation time compared with laparoscopic pneumovesical Cohen ureteral replantation.

ObjectiveTo clarify the differences in the efficacy and mechanism of different processed products of Atractylodes chinensis rhizoma by the pharmacodynamics and metabolomics studies of raw， bran-fried and rice water-processed products on rats with spleen deficiency. MethodSixty male SD rats were randomly divided into blank group， model group， raw product group（3.75 g·kg^-1）， bran-fried product group（3.75 g·kg^-1）， rice water-processed product group（3.75 g·kg^-1） and Shenling Baizhusan group（6.7 g·kg^-1）， with 10 rats in each group. The method of excessive fatigue+improper diet was used to establish a spleen deficiency model in rats. After the end of modeling， except for the blank and model groups， each dosing group was given the corresponding drug suspension， the immune organ coefficients of each group of rats were examined， the levels of interleukin-6（IL-6）， tumor necrosis factor-α（TNF-α）， immunoglobulin G（IgG）， amylase（AMS）， motilin（MTL）， gastrin（GAS）， Na⁺-K⁺-adenosine triphosphatase（ATPase）， aquaporin 2（AQP2）， AQP3 and AQP8 in rats were measured by enzyme-linked immunosorbent assay（ELISA）. Ultra high performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry（UPLC-Q-TOF-MS） combined with orthogonal partial least squares-discriminant analysis（OPLS-DA） were used to search for biomarkers in the plasma samples of spleen-deficient rats by using two criteria［P<0.05 and variable importance in the projection（VIP） value>1］， and to compare the different modulatory effects of the three decoction pieces on the splenic-deficient biomarkers， and metabolic pathway analysis was conducted through the Kyoto Encyclopedia of Genes and Genomes（KEGG） database. ResultCompared with the blank group， the thymus index and spleen index of rats in the model group were significantly decreased（P<0.05）， the levels of IL-6， TNF-α， IgG and AQP2 were significantly increased（P<0.05）， the levels of AMS， GAS， MTL， AQP3， AQP8 and Na⁺-K⁺-ATPase were significantly decreased（P<0.05）. Compared with the model group， raw products， bran-fried products and rice water-processed products all increased thymus index and spleen index（P<0.05）， decreased IL-6， TNF-α， IgG and AQP2 levels（P<0.05）， and increased AMS， GAS， MTL， AQP3， AQP8 and Na⁺-K⁺-ATPase levels to different degrees. A total of 176 differential metabolites were screened in the model group compared with the blank group， of which 75， 72 and 84 biomarkers were called back by the raw products， bran-fried products and rice water-processed products， respectively（P<0.05， P<0.01）. Raw products of A. chinensis rhizoma mainly affected glycine， serine and threonine metabolism. Bran-fried products mainly affected alanine， aspartate and glutamate metabolism， D-arginine and D-ornithine metabolism. Rice water-processed products mainly affected glycine， serine and threonine metabolism， alanine， aspartate and glutamate metabolism， citrate cycle， thiamine metabolism， D-arginine and D-ornithine metabolism. ConclusionRaw products， bran-fried products and rice water-processed products of A. chinensis rhizoma all have good spleen strengthening effects， among which the effects of bran-fried products and rice water-processed products were stronger. Meanwhile， raw products has the strongest dryness， followed by bran-fried products， and the weakest dryness of rice water-processed products. The three decoction pieces are able to significantly modulate metabolic abnormalities in spleen-deficient rats， and the mechanism may be related to amino acid metabolism such as glycine， serine and threonine metabolism as well as alanine， aspartate and glutamate metabolism.

BACKGROUND:Bone mineral density is the clinical gold standard for determining bone strength,but bone mineral density is less sensitive to changes in bone mass,with large changes in bone mineral density only occurring when bone mass is significantly reduced,so bone mineral density has limited ability to predict changes in bone strength and fracture risk. OBJECTIVE:A model of the normal and osteoporotic hip joint was developed to analyze the stresses and deformation in the hip of normal and osteoporotic patients under single-leg standing conditions. METHODS:A healthy adult female volunteer at the age of 36 years was selected as the study subject.The CT data of the hip joint of this volunteer were obtained and saved in DICOM format.The hip joint model was reconstructed in three dimensions,and the material properties were assigned by the gray value assignment method to obtain the normal and osteoporotic hip joint models according to the empirical formula.The same boundary conditions and loads were set to simulate the stresses and deformation in the normal and osteoporotic hip joints in the single-leg standing position. RESULTS AND CONCLUSION:(1)In the finite element model of the normal and osteoporotic hip,the stress distribution was more concentrated in the medial region of the femoral neck.(2)In the hip bone,the stress distribution was mainly concentrated in the upper part of the acetabulum.(3)The stress peaks in the medial femoral neck and upper acetabulum were larger in the normal hip model than in the osteoporotic hip model,probably due to the reduced bone strength of the osteoporotic bone.(4)The peak Von Mises of both normal and osteoporotic hip models were concentrated on the medial femoral neck,and the peak Von Mises of the hip bone was smaller,indicating that the overall effect of osteoporosis on hip bone stresses was relatively small.(5)In terms of deformation in the single-leg standing position,the maximum deformation in the normal hip model was located at the acetabulum and femoral head,and the maximum deformation was located at the upper part of the greater trochanter of the femur.(6)It is suggested that the finite element analysis method to model the values of parameters related to bone tissue in osteoporosis may improve clinical prediction of bone strength changes and fracture risk.It is explained from the biomechanical view that the intertrochanteric femur and femoral neck are good sites for osteoporotic hip fractures.

Objective It aims to construct an evaluation index system for the development level of intelligent health insurance,which can serve as a reference for health insurance management departments in assessing the develop-ment level of intelligent health insurance and the implementation of health insurance informatization.Methods Key events in intelligent health insurance were identified based on event system theory and text analysis.The evaluation index system was determined through a combination of expert interviews and Delphi expert consultations.The entro-py method was used to calculate the weights of each index,followed by the assessment of the current and ideal de-velopment levels.Results A total of 16 experts were consulted.After two rounds of Delphi expert consultation,two first-level indicators and 18 second-level indicators were finally included in the system.The current development level of intelligent health insurance in China is at the intelligent development stage(2.524 points),while the ideal de-velopment level is at the intelligent improvement stage(4.073 points).The positivity coefficient of both rounds of Del-phi expert consultation was 100%,with an authority coefficient of 0.842,and the degree of expert coordination im-proved with each round.Conclusion The constructed evaluation index system exhibits high scientificity,stability,and generalizability.It can provide an effective evaluation tool for the development of intelligent health insurance in various pooled areas.

Objective:To analyze the epidemiological and etiological characteristics of herpes pharyngitis (HA) in three prefectures of Jiangsu Province, and provide evidence for the prevention and control of HA in Jiangsu.Methods:Three surveillance sentinel hospitals in Wuxi, Suzhou and Yancheng were selected from May 2018 to December 2022, and information related to HA visits and hospitalized cases was regularly collected from the hospital inpatient management system by age groups. Enterovirus nucleic acid detection was performed by RT-PCR, and sequencing analysis, identification of genotype subtypes, and phylogenetic analysis were performed on the sequences of the gene encoding the coat protein VP1 of the main prevalent strains.Results:A total of 57 709 HA cases were recorded in the sentinel hospitals in in Wuxi, Suzhou and Yancheng, which was 1.76 times higher than the reported cases of hand, foot and mouth disease during the same period (57 709/32 831).The percentage of HA hospitalizations was 1.35% (781/57 709), and the percentage of hospitalizations showed an increasing trend from year to year ( χ2=62.79, P<0.001 ).The incidence peak of HA was during May-July. The cases were mainly children aged 12-59 months (67.07%, 38 708/57 709), with the highest case number in age group 36-59 months (34.40%, 19 852/57 709). The HA positivity rate was 33.82% (644/1 904); enterovirus A was predominant (54.04%, 348/644); of these, Coxsackievirus (CV)A6 accounted for the highest percentage (52.59%, 183/348), while CVA16 and CVA4 accounted for 24.71% (86/348) and 15.23% (53/348), respectively. All 10 CVA4 HA endemic strains belonged to the C2 gene subtype, and all 6 CVA6 HA endemic strains belonged to the D3a gene subtype; and were genetically closer to and related to the strains in some areas of China (Fujian Province, Guangzhou City, Jiangxi Province, Yunnan Province, Tianjin City, etc.). Conclusions:The disease burden of HA was heavy in 3 areas in Jiangsu, children in age group 12-59-month were mainly affected, and the annual incidence peak of HA was during May-July. The pathogens causing HA varied, but predominated by enterovirus A and had low intra-typical differentiation, and no new evolutionary branches were found, suggesting that it is necessary to include HA in foot and mouth disease surveillance or regarded as a notifiable communicable disease.

A series of chemotherapeutic drugs that induce DNA damage, such as cisplatin (DDP), are standard clinical treatments for ovarian cancer, testicular cancer, and other diseases that lack effective targeted drug therapy. Drug resistance is one of the main factors limiting their application. Sensitizers can overcome the drug resistance of tumor cells, thereby enhancing the antitumor activity of chemotherapeutic drugs. In this study, we aimed to identify marketable drugs that could be potential chemotherapy sensitizers and explore the underlying mechanisms. We found that the alcohol withdrawal drug disulfiram (DSF) could significantly enhance the antitumor activity of DDP. JC-1 staining, propidium iodide (PI) staining, and western blotting confirmed that the combination of DSF and DDP could enhance the apoptosis of tumor cells. Subsequent RNA sequencing combined with Gene Set Enrichment Analysis (GSEA) pathway enrichment analysis and cell biology studies such as immunofluorescence suggested an underlying mechanism: DSF makes cells more vulnerable to DNA damage by inhibiting the Fanconi anemia (FA) repair pathway, exerting a sensitizing effect to DNA damaging agents including platinum chemotherapy drugs. Thus, our study illustrated the potential mechanism of action of DSF in enhancing the antitumor effect of DDP. This might provide an effective and safe solution for combating DDP resistance in clinical treatment.
