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.

[Objective]To discuss the clinical experience of treating primary insomnia with Professor GU Xizhen, the famous Chinese doctor in Jiangsu Province. [Methods]To study the understanding of the etiology and pathogenesis of primary insomnia by Professor GU Xizhen, summarize the experience of treating primary insomnia based on the use of the key suppressing Yang and basing on the syndrome differentiation.[Results]Professor GU Xizhen thinks that the movement of the Ying and Wei is the most important physiological mechanism for the formation of sleep, and that Yang does not enter the Yin is the basis of the pathologic theory, the deficiency of Qi and blood and the dysfunction of the viscera are the pathogenic factors. Based on the urgent cure of the symptoms, delayed treatment of the fundamental principles, put forward the treatment when suppressing Yang into Yin first, on the basis of the emphasis on tonifying Qi and blood, Yin and Yang, clearing heat, removing the wet, regulating Qi activity etc, matching specific time of the drug. It can relieve both primary and secondary symptoms and get good results.[Conclusion]The treatment of primary insomnia by the Professor GU Xizhen is very effective. It deserves further study and promotion in clinical practice. One medical case is attached to prove the above conclusion.

This paper described the market reform′s influence and the healthcare reform on medical behaviors of both doctors and patients.It is held that the healthcare reform should ensure the public welfare nature of public hospitals and focus on medical quality and patient′s health,so as to promote the harmonious development of the doctor-patient relationship from the policy and practice aspect.

Objective: To evaluate the new compensation mechanism for primary healthcare institutions in Zhejiang province, in terms of fairness, performance, incentive mechanism and sustainability in pilot areas. Methods: Evaluation indicators were constructed based on stakeholder theory, fairness theory, expectation theory and sustainable development theory.Focus group interviews were conducted with stakeholders and quantitative data were collected through questionnaires. Meanwhile, the financial compensation, income and expenditure and work equivalent data were collected from such institutions of the four pilot areas, with quantitative data subject to descriptive analysis. Results: This study found the reform used reasonable proportion of funds allocated(the proportion of basic salary for employees was lower than 50%)and adjustment factors(1.0-1.8)of different primary healthcare institutions to guarantee the fairness of the reform; the increase of work equivalents(the per capita work equivalents of medical staff in pilot counties had increased from 38.435 million in the previous year to 42.590 million work equivalents)reflected the performance outcomes of the reform. The incentive and sustainability of the reforms were the weak parts. These were mainly due to the fact that the internal distribution system of primary healthcare institutions failed to make corresponding reforms. Conclusions The reform of the compensation mechanism based on the equivalent method has changed medical staff′s perception of the distribution of funds. The principle of" more pay for more work" and the use of information technology to capture work equivalents have improved the enthusiasm of primary medical staff and the operational efficiency of these institutions, thus, making reform generally scientific and reasonable.

Objective:To investigate the application value of computed tomography (CT) and magnetic resonance imaging (MRI) examination in clinical diagnosis of gallbladder tumor with perigallbladder invasion.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 80 gallbladder tumor patients with perigallbladder invasion who were admitted to 3 medical centers (21 cases in The First Affiliated Hospital of Northwest University, 42 cases in The First Affiliated Hospital of the Air Force Medical University, 17 cases in The First Affiliated Hospital of Dalian Medical University) from January 2021 to December 2022 were collec-ted. There were 45 males and 35 females, aged (56±4)years. Observation indicators: (1) CT and MRI examinations; (2) surgical conditions. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) CT and MRI examinations. Of 80 patients, cases with gallbladder cancer and gallbladder adenoma were 73 and 7, respectively. Cases with endoluminal nodular type, mass type and localized thick-walled type were 33, 39 and 8, respectively, with tumor diameter as 1.55 cm×1.35 cm×1.33 cm, 1.64 cm×1.37 cm×1.36 cm and 5.72 cm×4.07 cm×4.36 cm. Results of CT examination of endoluminal nodular type showed local nodular protrusions into the endoluminal area, and local enhancement on enhanced scanning. Results of CT examination of localized thick-walled type showed the cavity wall of lesion was locally or diffusely irregul-arly thickened, with a thickness of 1.10(range, 1.10-2.21)cm. Of 80 patients, results of CT and MRI examinations showed invasion of liver parenchyma in 68 cases, which was manifested as local mass, blurred demarcation, and abnormal protrusion. The maximum depth was (4.22±0.25)cm, (4.22±0.22)cm, (4.28±0.16)cm of cross-sectional, coronal, sagittal view in CT examination, respectively. The minimum depth was (0.22±0.10)cm, (0.25±0.08)cm, (0.24±0.12)cm. The depth of liver parenchyma invaded was (1.64±1.38)cm, (1.68±1.46)cm, (1.66±1.40)cm. Results of CT and MRI examinations showed invasion of perigallbladder, which was manifested as local invasion of the gastric antrum in 12 cases. (2) Surgical conditions. Of 80 patients, results of CT and MRI examina-tions showed that 60 patients had localized masses in the gallbladder cavity with or without infiltration of surrounding tissues. After confirming the absence of other organs and distant metastasis, cases undergoing radical resection and palliative resection were 44 and 16, respectively. Results of CT and MRI examina-tions showed that 20 patients had malignant gallbladder tumors with peri-pheral liver infiltration and multiple intrahepatic metastases with distant organ metastases, which were unresectable.Conclusion:For patients with gallbladder cancer and perigallbladder invasion, CT or MRI examina-tions can show their structural characteristics.

Objective:To investigate the application value of intraoperative motor nerve monitoring in cervical neurogenic tumor surgery.Methods:The efficacy of intraoperative neuromonitoring (IONM) was analyzed retrospectively in 18 patients, including 6 males and 12 females, aged from 15 to 74 years, treated in Affiliated Drum Tower Hospital, Medical School of Nanjing University from June 2019 to September 2022 who underwent total cystectomy of cervical neurogenic tumors under intraoperative nerve monitoring.Results:All 18 patients had complete tumor removal, including 8 patients with tumors from the vagus nerve and 10 patients with tumors from the brachial plexus nerve. Postoperative nerve functions were normal in patients with tumors from brachial plexus nerve, and incomplete vocal cord paralysis occurred in 2 patients with tumors from vagus vagus nerve. The total incidence of motor nerve injury was 11.1% (2/18). All patients were followed up for 6 to 45 months, with no tumor recurrence.Conclusion:Intraoperative neuromonitoring has significant values in surgery of cervical neurogenic tumors, which is helpful to remove completely the tumors on the basis of protecting the nerve functions to the maximum extent.
