The experience of various countries proves that the hierarchical diagnosis and treatment model can lead to reasonable resources allocation and utilization, however, the waste of China''s disordered treatment model has not been estimated.Nowadays, it is very important to establish a hierarchical diagnosis and treatment system during China''s healthcare system reform.Therefore, it is necessary to estimate the benefit the reform may bring.We take Zhejiang Province as an example, and adopted the system dynamics model to build the health delivery system, to emulate the hierarchical diagnosis and treatment model and the disordered model, and to evaluate the benefit.Results showed that if first option at the primary health institutions increased 10%, it could save 0.251 billion yuan, and if increased 15%, it could save 0.39 billion yuan.If the first option at the primary health institution reached 72.35% and the treatment in county reached 90%, the outpatient in tertiary hospital could reduce by 13 million, and those in primary healthcare institutions could increase by 74 million yuan.The direct healthcare cost could reduce 3.016 billion Yuan.

Background:Zinc finger protein of cerebellum 2(ZIC2)is a transcriptional activator or repressor that is important for the organogenesis of the central nervous system.Previous studies have reported that ZIC2 is widely upregulated in a variety of tumors. Methods:Oncomine database was used to evaluate the expression levels of ZIC2 in hepatocellular car-cinoma(HCC)and normal liver tissues.Quantitative real-time polymerase chain reaction and immu-nohistochemistry were conducted to validate the results from the database.Cox regression analysis and survival curves were performed to assess the survival effect of ZIC2 in HCC. Results:Increased expression of ZIC2 was detected in HCC tissues compared with normal liver tissues.In addition,patients with high ZIC2 levels had a poor prognosis.Multivariate analysis showed that clinical stage(T or M classification)and ZIC2 levels were independent prognostic factors for overall survival.Moreover,a subgroup analysis revealed that patients with moderate or poor grade tumors,T1-2 tumors,N0 tumors,early American Joint Committee on Cancer(AJCC)stage,and old age were more likely to present with overexpression of ZIC2.To conclude,ZIC2 is upregulated in HCC and associated with the histology and survival of HCC patients. Conclusions:The expression status of ZIC2 may serve as an independent prognostic marker of HCC.

Objective:To understand and analyze the current situation of core competence of graduate midwives in standardized training in Sichuan Province, so as to provide a reference for the training of midwives in Sichuan Province.Methods:A total of 102 midwives who participated in standardized training and graduated from July 2016 to June 2018 in Sichuan Province were investigated by using general information questionnaire (including 14 items of general information, occupational literacy and hospital conditions) and Midwives Core Competence Scale (including 54 items and 6 dimensions). Among 109 questionnaires distributed, 102 valid questionnaires were collected. SPSS 21.0 was used to analyze the results by single factor analysis and multiple linear regression analysis.Results:The average total score of the core competency scale in this study was (203.470±32.398). The scores of postpartum health care and prenatal health care were relatively high, while the score of public health care was relatively low. Multivariate regression analysis showed that whether the maternal and infant health certificates were obtained during the training period, and whether there was a training system for midwives alone and arrangements of department rotation were the influencing factors of the core competence of the graduate midwives ( P<0.05). Conclusion:The core competence of midwives in standardized training in Sichuan province is at the middle level. The standardized training of midwives is at the initial stage and lack of systematic management. Hence, it is urgent to build a unified and standardized training system.

To investigate the effectiveness and safety of diverticular peroral endoscopic myotomy (D-POEM) for mid-esophageal diverticulum. Data of consecutive patients in the prospective database with mid-esophageal diverticulum who received D-POEM in West China Hospital, Sichuan University between April 2014 to September 2019 were collected. The modified Eckardt scoring system for mid-esophageal diverticulum was used to evaluate the severity of diverticular symptoms. The effectiveness and safety of D-POEM were evaluated in terms of clinical success, technical success, complications and recurrence. A total of 7 patients with mid-esophageal diverticulum were included. Clinical and technical success was achieved in all patients with operation time of 16-70 minutes. No serious complications (2 cases with minor complications) or recurrence occurred. The follow-up time was 2-16 months. The median modified Eckardt score decreased from 3 points before operation to 0 points after operation. It is preliminarily believed that D-POEM ensures a complete septotomy between normal esophageal lumen and esophageal diverticulum. It is a safe and effective technique for mid-esophageal diverticulum. The modified Eckardt scoring system is suitable for symptom evaluation before and after treatment of mid-esophageal diverticulum.

BACKGROUND:Computer-assisted implant surgery can improve implantation accuracy,but the use of implant template in the posterior tooth area is limited for patients with small opening and small interocclusal distance.Therefore,the digital guide has been improved. OBJECTIVE:To study the effect of modified implant template on the accuracy of assisted implantation in missing second molars. METHODS:From July 2020 to July 2023,40 patients who received digital guide plate implantation or free hand implantation to repair missing second molars were selected from First Affiliated Hospital of Guangzhou Medical University.According to the coin toss method,patients were randomly divided into a trial group(n=22;modified digital guide assisted implantation)and a control group(n=18;free hand implantation).The data of neck deviation,tip deviation,depth deviation,and angle deviation were compared between groups for preoperative and postoperative cone beam CT overlap analysis.One week after the operation,the patients'satisfaction with the operation was assessed by visual analog scale score. RESULTS AND CONCLUSION:(1)The trial group included 25 implants(12 in the upper jaw and 13 in the lower jaw);the control group included 23 implants(8 in the upper jaw and 15 in the lower jaw).The neck deviation,tip deviation,depth deviation,and angle deviation of the trial group were all smaller than those of the control group(P<0.05,P<0.001).There was no significant difference in accuracy between the maxillary and mandibular implant site in the trial group(P>0.05).(2)There was no significant difference in satisfaction with the operation between the two groups(P>0.05).(3)The results showed that improving the digital guide plate for assisted implantation for missing second molar can improve surgical accuracy and is suitable for patients with small opening and small interocclusal distance in the posterior tooth area.

Background: Serum C-peptide results from various routine methods used in China are highly variable, warranting well-performing methods to serve as an accuracy base to improve the harmonization of C-peptide measurements in China. We developed an accurate isotope dilution liquid chromatography-tandem mass spectrometry (ID-LC–MS/MS) method for serum C-peptide measurement and explored its use in harmonization. Methods: After protein precipitation with ZnSO4 solution, C-peptide was extracted from serum samples by anion-exchange solid-phase extraction and quantified by ID-LC–MS/MS in positive ion mode. The precision and analytical recovery of the ID-LC–MS/MS method were assessed. Seventy-six serum samples were analyzed using the ID-LC–MS/MS method and six routine immunoassays. Ordinary linear regression (OLR) and Bland-Altman (BA) analyses were conducted to evaluate the relationship between the ID-LC–MS/MS method and routine immunoassays. Five serum pool samples assigned using the ID-LC–MS/MS method were used to recalibrate the routine assays. OLR and BA analyses were re-conducted after recalibration. Results: The within-run, between-run, and total precision for the ID-LC–MS/MS method at four concentrations were 1.0%–2.1%, 0.6%–1.2%, and 1.3%–2.2%, respectively. The analytical recoveries for the ID-LC–MS/MS method at three concentrations were 100.3%–100.7%, 100.4%–101.0%, and 99.6%–100.7%. The developed method and the immunoassays were strongly correlated, with all R2 >0.98. The comparability among the immunoassays was substantially improved after recalibration. Conclusions The performance of the ID-LC–MS/MS method was carefully validated, and this method can be used to improve the harmonization of serum C-peptide measurements in China.

Lead poisoning severely threatens human health with its cumulation and durability in the body. The analysis of lead in blood is vital for screening, diagnosis, treatment, and prognostication of lead poisoning and for indirectly monitoring the level of lead in the environment. Although the detection programs are available throughout our country, the accuracy and comparability of the results cannot meet the expectation. A variety of factors can affect the accuracy of blood lead testing. To promote the application of blood lead analysis in clinical trials and reduce the bias of results, a better reference system for blood lead analysis should be established to evaluate the accuracy of traditional methods, promote the standardization of blood lead analysis and achieve accurate blood lead testing.

Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound,the examiner and interpreter of the image are critical care medicine physicians.The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes.With the idea of critical care medicine as the soul,it can integrate the above information and clinical information,bedside real-time diagnosis and titration treatment,and evaluate the therapeutic effect so as to improve the outcome.CUS is a traditional technique which is applied as a new application method.The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept,implementation and application of CUS.It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure.At the same time,the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications,and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS.Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group,based on the rich experience of clinical practice in critical care and research,combined with the essence of CUS,to learn the traditional ultrasonic essence,established the clinical application technical specifications of CUS,including in five parts:basic view and relevant indicators to obtain in CUS;basic norms for viscera organ assessment and special assessment;standardized processes and systematic inspection programs;examples of CUS applications;CUS training and the application of qualification certification.The establishment of applied technology standard is helpful for standardized training and clinical correct implementation.It is helpful for clinical evaluation and correct guidance treatment,and is also helpful for quality control and continuous improvement of CUS application.
