Objective: To investigate patients' satisfaction rate towards referral in a class A tertiary hospital, so as to provide the evidence for promoting the highly efficient implementation of referral. Methods : The gender, age, type of referral, referral efficiency and referral cost of patients receiving referral services in 2021 were collected through the interconnected intelligent hierarchical diagnosis and treatment collaborative platform of Henan Provincial People's Hospital. Patients' awareness and recognition of the two-way referral system were investigated using questionnaire surveys, and factors affecting patients' satisfaction with referral were identified using a multivariable logistic regression model. Results: A total of 1 268 patients receiving referral services were surveyed, including 576 men (45.43%) and 692 women (54.57%), and the respondents were predominant at ages of 18 years and older (935 cases, 73.74%). There were 535 cases with overdue referral (42.19%) and 1 157 cases with free referrals (91.25%). There were 749 cases that were aware of the two-way referral system (59.07%), and 587 cases recognized the two-way referral system (46.29%). There were 975 patients with a satisfactory attitude towards referral, with a satisfaction rate of 76.89%. There were 1 030 cases (81.23%) that considered fluent communication of referral information, with a 78.54% satisfaction rate towards referral; 569 cases (44.87%) that considered simple referral procedures, with an 81.37% satisfaction rate towards referral, and 797 cases that were satisfied with the services provided by the referred medical staff (62.85%), with a 79.42% satisfaction rate towards referral. Multivariable logistic regression analysis showed that non-overdue referrals (OR=1.846, 95%CI: 1.411-2.414), free referrals (OR=1.815, 95%CI: 1.188-2.773), awareness of the two-way referral system (OR=0.624, 95%CI: 0.472-0.826), recognition of the two-way referral system (OR=1.621, 95%CI: 1.235-2.129) were factors affecting the satisfaction with referral. Conclusions The satisfaction rate towards referral was 76.89% among the study patients, and the awareness and recognition of the two-way referral system, referral efficiency and convenience are factors affecting the satisfaction with referral.

Objective To investigate the elinicopathologic features of atypical endometriosis(AEM) and to discuss the relationship between AEM and tumors. Methods A retrospective analysis was performed of 163 cases of AEM, which were retrieved from the Department of Pathology files at the Tianjin Central Obstetrics and Gynecology Hospital between Jan 2004 and Dec 2006. The pathologic changes of AEM including its glandular epithelium, stroma, background and the conditions coexisting with tumor were observed. Results The AEM accounted for 4.38% (163/3724) of the endometriosis (EM) eases. Of 172 AEM foei of 163 patients, 168 were in the ovary, and the other 4 were in the fallopian tube, cervix and uterine serosa respectively. The rate of ovarian AEM was 6.81% of endometriosis. AEM associated with tumour was found in 26 cases (15.95% )and among 27 of ovarian AEM, 15 were malignant, 9 borderline and 3 benign. The AEM epithelia were mainly arranged in the form of surface epithelium. They present with characteristic features of moderate to marked pleomorphism, epithelial tufting and bud structures by microscopy. The walls of AEM cyst were presented with three layers of epithelium, endometrioid stroma and fibrosis-collngen. The endometrioid stroma were usually thin in contrast to the fibre-collagen tissue, which was often thick with scarred background. The transformation from AEM to tumor was found in most of the malignant tumors( 14/15,93% ). Conclusions AEM lesions hold some features of both EM and tumor, which may have a relatively higher potential for tumorigenesis and cancerafion. The process of damage and repair in EM foci during a long course may play a role in the development of EM into AEM and finally into tumor.

AIM　To explore the effect of berberine in inhibition of proliferation and induction of apoptosis of gastric cancer cell MGC-803.METHODS　The MGC-803 cell morphology and cell counting were studied by Trypan blue, MTT, Methyl green pyronin stain assay, the MGC-803 cell DNA changes were investigated by flow cytometry and agarose gel electrophoresis.RESULTS　Berberine could significantly inhibit the growth of MGC-803. After 48 hours of treatment with different concentration berberine (8, 4, 2, 1 mg*L-1), the inhibitive rate of MGC-803 were 86.7%, 65.9%, 20.0%, 0%, respectively. Meanwhile, MGC-803 showed typical apoptosis features: cell shrinkage, nuclear condensation, DNA fragmentation and formation of apoptotic bodies. A typical subdiploid peak before G0/G1 phase was observed by flow cytometry. The Trypan blue stain achromatophilia rates of death cells, which with well membranes, were between 60%～82%. Agarose gel electrophoresis analysis, which showed that the chromosomes of MGC-803 were broken by berberine before the structures of membrane were damaged, while DNA broke into long fragments rather than small fragments, supported that the activation effect of berberine on nuclease was mild.CONCLUSION　Berberine could significantly inhibit proliferation of gastric cancer cell MGC-803 and induced apoptosis, and the cytotoxicity of berberine on MGC-803 was weak.

Objective To observe the effect of Shenxian Yiganling Tablets ( SYT) , a Chinese herbal recipe with the actions of tonifying kidney and removing toxicity, combined with HBsAg gene-modified dendritic cells (DC/HBsAg) on immune response and hepatocyte damage of hepatitis B virus (HBV) transgenic mice. Methods HBV transgenic mice ( Tg mice) were immunized with injection of DC/HBsAg ( 100 μg every three weeks) through caudal vein, and then were given intragastric administration of SYT in the dosage of 12.8, 23.5, and 47.0 mg/d for four weeks. HBV Tg mice splenic T cell cytokines of interleukin 2 ( IL-2) and interferon gamma ( IFN-γ) levels as well as serum alanine aminotransferase ( ALT) and aspartate aminotransferase ( AST) conents were detected by enzyme-linked immunosorbent assay ( ELISA) . Lactate dehydrogenase ( LDH) release assay was used to detect the in-vitro cytotoxic activity of splenic HBsAg specific T lymphocytes. Serum HBsAg level of HBV Tg mice was detected by ELISA after immunization. Results Compared with DC/HBsAg administration alone, DC/HBsAg combined with SYT could significantly increase HBV Tg mice splenic T cells cytokines IL-2 and IFN-γ levels ( P<0.05 or P<0.01) , increase the cytotoxic activity of HBsAg-specific T lymphocytes ( P<0.05 or P<0.01), increase the inhibition rate of HBsAg expression (P<0.05 or P<0.01), and reduce hepatocyte damage. Conclusion SYT could enhance the immune response of Tg mice to DC/HBsAg immunization, and relieve the hepatic damage, which enable the HBV clearance process out of hepatic damage in the case of anti-HBV activity of IFN-γbeing unaffected.

OBJECTIVETo study the possibility of metallothionein (MT) participating in the process of ischemia/reperfusion protection.

METHODSThe model of pig latissimus dorsi island flap and cultured myocytes were used in this study. The island flap was preconditioned with ischemia and the cultured myocytes were treated with anoxia. MT was detected in the flap and the cultured myocytes instantly and at 12 and 24 hours after the treatment. The protection effect of precondition on flap ischemia/reperfusion damage was observed by recording flap necrosis and the serum LDH level. The protection effect of precondition on myocyte anoxia/reoxygenation damage was observed by recording the cell survival rate and MDA content. The change in the protection effect was also observed after the MT was inhibited by PD098059.

RESULTSThe content of MT in cultured myocytes increased obviously 12 hours after precondition. Similar result was observed in flap tissue 24 hours later. Compared with the non-conditioned flap, the necrosis areas of the preconditioned flaps were smaller, the serum LDH was lower. The survival rate of preconditioned cultured myocytes was higher compared with non-conditioned cells (P < 0.05). The content of MDA and the quantity of discharged LDH were less (P < 0.05). When MT was inhibited by PD098059, the delaying protection of precondition disappeared. The observed quotas at that time were the same with those of simple I/R or A/R groups (P > 0.05).

CONCLUSION24 hours after precondition, the flap and the cultured myocytes are protected from re-damage of I/R or A/R. MT is involved in this process.
