0.05). After dividing the patients into early-onset and late-onset subgroups, there were significant differences of DRD4 genotype and allele frequency between early-onset patients and controls (P0.05). Conclusion The results suggested that the polymorphism of DRD4 receptor gene may be associated with early-onset OCD. The 3/4 genetype may be the risk factor of early-onset OCD. Early-onset and late-onset OCD may have different etiology.

Objective:To investigate the optimal emergency endoscopy timing in patients with esophagogastric variceal bleeding (EGVB).Methods:The clinical data of patients with EGVB emergency endoscopy in Renmin Hospital of Wuhan University from December 2018 to November 2020 were collected and analyzed. According to the time interval from admission to the start of emergency endoscopy, they were divided into emergency endoscopy group (<6 h, n=115) and early endoscopy group (6-24 h, n=57). The baseline data, clinical efficacy and postoperative situation of the two groups were compared, and the risk factors of 6-week mortality of EGVB emergency endoscopy were analyzed by univariate and multivariate analysis. Results:In terms of baseline characteristics, there were no significant differences in age, gender, causes, shock index, model for end-stage liver disease (MELD) score, charlson complication index (CCI) score, portal hypertension related complications between the two groups ( P<0.05). However, the albumin (ALB) in emergency endoscopy group was significantly lower than that in early endoscopy group ( P<0.001). There were significant differences in Child Pugh grading and Child Pugh score between the two groups ( P=0.002, P=0.001). In terms of endoscopic efficacy, the detection rate of bleeding site in emergency endoscopy group was significantly higher than that in early endoscopy group (90.4% and 73.7%, P<0.05). There was no significant difference in operation duration, immediate hemostasis success rate, 5-day rebleeding rate, rescue treatment demand and 6-week mortality between the two groups ( P>0.05). There was no significant difference in bleeding related death between the two groups ( P>0.05). In addition, there was no significant difference in blood product consumption, intensive care unit (ICU) stay and total hospital stay between the two groups ( P>0.05). Multivariate analysis showed that Child Pugh grade C ( P=0.018), MELD score ( P=0.005) and CCI score ( P=0.001) were independent risk factors for 6-week death outcome of EGVB patients, while emergency endoscopic intervention time was not related to 6-week death outcome ( P=0.5). Conclusions:The efficacy of early endoscopic intervention is no worse than that of emergency endoscopic intervention, except for the identification of bleeding site. Child-Pugh grade C, MELD score, and CCI score are the independent risk factors for 6-week mortality, while the timing of emergency endoscopy is not associate with 6-week mortality in EGVB patients.

Performance management is a key direction of the reform of the national medical and health system, and it is also an important starting point for promoting the development of hospital connotation. In view of the contradiction among the current hospital performance distribution system, this paper proposes a design mentality of performance distribution system based on homogenization subsidy base, and expounds the basic connotation and cognitive basis of homogenization subsidy base. The key elements of the design of the performance distribution system are discussed from four aspects: pre-adjusted total control, coefficientized personnel attendance, same performance appraisal, and homogenization subsidy base. At the same time, this paper also analyzes the characteristics of the performance distribution system based on the homogenization subsidy base. The application prospects of the performance distribution system are prospected from three aspects: the national medical reform requirements, the discipline development discipline and the system's own characteristics.

OBJECTIVETo compare the difference in the clinical efficacy on cervical spondylosis of vertebral artery type (CSA) treated with thermosensitive moxibustion at different dosages.
METHODSSixty cases of CSA were randomized into a saturated moxa dosage group and a regular moxa dosage group, 30 cases in each one. The thermosensitive moxibustion was adopted in the two groups. The mild suspended moxibustion was applied at two acupoints with the strongest thermosensitization. In the saturated moxa dosage group, the moxibustion time was determined by the disappearance of thermosensitization. In the regular moxa dosage group, 15 min was required on each acupoint. The treatment was given twice a day for first 4 days in the two groups. Since the 5th day, the treatment was given once a day, continuously for 10 times, and totally 14 days were required. The score of symptoms and function and clinical efficacy were compared between the two groups before and after treatment as well as 6-month follow-up after treatment.
RESULTSThe curative and effective rate was 56.7% (17/30) after treatment and 60.0% (18/30) in 6-month follow-up after treatment in the saturated moxa dosage group, which were superior to 26.7% (8/30) and 30.0% (9/30) in the regular moxa dosage group respectively (P < 0.01, P < 0.05). The scores of clinical symptoms and function after treatment and in follow-up were improved apparently as compared with those before treatment in both groups (all P < 0.01). The scores of clinical symptoms and function after treatment and in follow-up in the saturated moxa dosage group were increased much more apparently than those in the regular moxa dosage group (after treatment: 22.32 +/- 4.64 vs 17.43 +/- 3.21; in follow-up: 23.01 +/- 4.76 vs 18.32 +/- 2.13, both P < 0.01).
CONCLUSIONThe thermosensitization moxibustion of saturated dosage achieves the superior short-term and long-term efficacies in the treatment of CSA as compared with the regular moxibustion dosage.
