OBJECTIVE To evaluate the cost-utility of ciclesonide （CIC） versus budesonide （BUD） for the maintenance treatment of mild to moderate bronchial asthma. METHODS From the perspective of Chinese health service system， a Markov model was established based on the data from a clinical trial in China and some literature. The cycle length was 1 week， the time horizon was 60 years. A discount rate of 5% per year was applied. Cost-utility analysis was performed on therapeutic scheme of CIC and BUD using three times of China’s per capita gross domestic product （GDP） in 2023 as the threshold of willing-to-pay （WTP）. One-way sensitivity analysis， probabilistic sensitivity analysis and scenario analysis were applied to test the uncertainty of basic analysis. RESULTS Compared with BUD scheme， the incremental cost of the CIC scheme was 9 401.67 yuan， and the incremental quality-adjusted life years（QALYs） were 0.001 3； incremental cost-effectiveness ratio （ICER） was 6 928 868.26 yuan/QALY， far beyond the threshold of WTP 268 074 yuan/QALY. One-way sensitivity analysis showed that the usage， dosage and unit price of CIC and BUD were parameters that had a significant impact on ICER； probabilistic sensitivity analysis showed that the basic analysis results were relatively robust； scenario analysis showed that， when the price of CIC reduced to 159.95 yuan/branch， the probability of CIC scheme having economics was similar to that of BUD scheme. CONCLUSIONS At the current price， CIC is not economical compared with BUD for the maintenance treatment of mild to moderate asthma， using three times of China’s GDP in 2023 as the threshold of WTP.

At present, there is no effective drug treatment for obstructive sleep apnea hypopnea syndrome (OSAHS). It is usually treated by mechanical ventilation through a ventilator. In this paper, a non-invasive bi-level breathing therapy system suitable for home scenarios is developed. The system supports single-level and bi-level positive airway pressure therapies, and introduces the function of inspiratory synchronous trigger based on flow monitoring to enhance the synchrony of patient-ventilator synchronization. The test results show that the performance indicators of the system meet expectations. Each ventilation mode can operate normally and can meet the requirements for the use of home non-invasive ventilators.

Objective:To evaluate the clinical effect of orbital fat releasing and repositioning through supra-suborbicularis oculi fat (SOOF) in lower eyelid blepharoplasty.Methods:The authors retrospectively analyzed the clinical data of patients who received lower eyelid blepharoplasty in the Department of Plastic Surgery, Beijing Tsinghua Changgung Hospital from January 2017 to January 2023. Lower eyelid blepharoplasty with orbital fat releasing and repositioning through supra-SOOF was performed. The tear trough ligament and orbicularis retaining ligament were released between the orbicularis oculi muscle and SOOF via skin approach. Orbital septal fat was released to this space, lateral fat flap was fixed to the SOOF capsule, medial fat flap was fixed to the superficial fascia of the levator labii superioris muscle, orbital septum was repositioned, and lateral canthus was suspended. After the operation, lower eyelid morphology and complications were evaluated.Results:A total of 58 patients were enrolled, including 8 males and 50 females with the age of (49.8 ± 10.4) years (32 to 70 years). All patients had obvious lower eyelid bags on both sides, combining the tear trough deformity and (or) palabromalar groove. Fifty-seven patients were followed up for (29.1 ± 16.9) months (6-67 months). All patients were satisfied with the operation. The appearance of lower eyelid was greatly improved, with elimination of fat prominence and tear trough deformity. Mild lower eyelid ectropion was observed two cases 1 week after the operation, and were relieved by moderate massage 2 weeks postoperatively. In one case, mild lower eyelid retraction was observed 1 month postoperatively, with no complaint of discomfort or further treatments. Bulbar conjunctival hemorrhage occurred in 1 case and recovered without further interventions.Conclusion:Lower eyelid blepharoplasty with orbital fat releasing and reposting through supra-SOOF can effectively release the tear trough ligament and the orbicularis retaining ligament, with stronger fat fixation and less surgical difficulty. After the operation, eyelid contour was flat and tight with fewer complications and higher patient satisfaction.

To explore the pathogenesis and treatment of recurrent granulomatous mastitis based on "deficiency， toxin and blood stasis". It is believed that the main pathogenesis of recurrent granulomatous mastitis is spleen and stomach deficiency due to chronic illness， and at the same time， the persistent or intermittent presence of various causes makes the residual toxin unclear， which leads to the stagnation of local meridians and collaterals in the breast， accumulation of lumps， and then suppuration. Deficiency of qi and blood in zang-fu organs is the main cause of this disease， and residual toxin is the key factor of this disease. The treatment should focus on promoting therapy， promoting with dispersing， expelling with supplementing， supplementing with warming and dredging， dissolving toxins and releasing stasis， and the prescription is based on modified Tuoli Xiaodu Powder （托里消毒散） or self-prescribed Jiangru No.2 Formula （浆乳2号方）. Overall， the treatment should combine deficiency， toxin and blood stasis with different syndrome differentiation and treatment， reinforce healthy qi and express toxin， and activate blood circulation and dredge collaterals with flexibly modification， to promote disease healing.

Objective:To introduce the health insurance fund supervision model in Japan,compare the current situation of health insurance fund supervision in China,learn from experiences,and propose suggestions for improvement.Methods:By combining cases and regulatory effects,it introduces Japan's"guidance-inspection"based health insurance fund supervision model.Results:Japan's"guidance-inspection"based health insurance fund supervision model is relatively effective.Compared with China,it has a higher level of organizational hierarchy,focuses on education in its supervisory approach,clarifies the direction of patients'self-paid expences,and has a well-developed dual-way communication mechanism.Conclusion:China should establish a comprehensive health insurance fund supervision pathway,clearly define the resolution pathway for self-paid expenses caused by violations,and improve the mechanisms for negotiation and dispute resolution during the process.
