China's mental health service system is transitioning from an expansion-oriented stage focused primarily on addressing resource shortages and improving access to care toward a more mature stage that places greater emphasis on service quality， operational efficiency， patients' rights， and long-term outcomes. The principal challenge is no longer merely an insufficient overall supply of mental health resources， but rather inadequate alignment among service goals， the structure of service provision， payment incentives， allocation of responsibilities， and professional capacity. Recent incidents involving inappropriate psychiatric admissions and misuse of medical insurance funds in a small number of institutions， although not representative of the mental health sector as a whole， have exposed several structural risks within an inpatient-dominated service model. These include misalignment between inpatient services and medical insurance payment incentives， expansion of institutions and beds outpacing the development of professional capacity and quality governance， excessive concentration of social-risk management responsibilities in medical institutions， and inadequate continuity of care across hospitals， communities， and families. In practice， psychiatric hospitalization may simultaneously serve the multiple functions of clinical treatment， institutional financing， and the management of social risks. When the boundaries among these functions are unclear， and outpatient care， day services， community-based rehabilitation， and social support lack stable institutional and financial support， hospitalization may become systematically overused. The next stage of reform should shift mental health services from a hospital- and inpatient-dominated model toward a stratified and continuous system centered on patients' needs； establish medical insurance payment and evaluation mechanisms that balance costs， quality， functional outcomes， and long-term value； clarify the responsibilities of medical institutions， communities， families， and relevant government sectors； and make professional competence， ethical standards， patients' rights， and institutional governance the foundations of quality improvement. The key to the high-quality development of mental health services in China lies neither in simply increasing or reducing the number of psychiatric beds nor solely in strengthening post hoc regulation， but in aligning institutional incentives with patients' interests and promoting symptom improvement， functional recovery， and social participation.

OBJECTIVEAccording to the characteristics of digital medicine and the demands of digitalized management in hospitals, we established a storage system that is affordable, highly expandable, and reliable.

METHODSThe multi personal computer storage system (MPCSS) was constructed using hardware and software. The image data were archived from major servers to storage personal computers (PCs) by using Neusoft-picture archiving and communication system (PACS) and backed up on storage PCs. We simulated data loss on storage PCs and then restored the data. We also expanded the storage system to enlarge its capacity.

RESULTSThe average transfer rate from MPCSS was 27.7 MB/s, and the average cost for this system was yen 74/GB. In the testing stage, only 6 of 187 instances of data retrieval (from 100 patients) failed.

CONCLUSIONThe MPCSS is much less expensive than other high capacity systems or devices. It is feasible and suitable for digital image storage.

Objective According to the characteristics of digital medicine and demand of digitized management in hospital, we establish a storage system which is cheap, highly expansible, and reliable. Methods The multi personal computer storage system (MPCSS) was constructed by assembling the hardwares and softwares. The image data were archived from major server to storage PC by using NEUSOFT PACS archiving manage system and backuped on storage PC. We simulated the situation that the data on storage PC was lost and restored the data. We also expanded the storage system to enlarge its capacity. Results Average transfer rate from MPCSS was 27 7 Mbit/s (1 byte=8 bit); average cost for this system was 74 RMB/G; six cases in the 187 repeated reading of 100 patients failed. MPCSS can store backup and restore the image data, and can expand the storage size. Conclusion MPCSS is very cheap compared with other high capacity systems or devices. It is feasible and suitable for digital image storage.
