Objective To report a family with lipoid proteinosis (LP) from Shandong province and to analyze mutations in the extracellular matrix protein 1 (ECM1) gene in this family.Methods Eight members in a threegeneration family with LP were clinically investigated,and two patients were identified to suffer from LP,including the proband (Ⅲ 1) and her mother (Ⅱ 2).Both of the patients presented with papules on the palpebral margin,short and thick lingual frenum,and hoarseness.Indirect laryngoscopy showed infiltrating and thickening of the vocal cord.Pathological examination of lesions on the palpebral margin and laryngeal mucosa revealed deposits of hyaline-like material in the dermis,which was strongly positive for periodic acid-Schiff (PAS) staining and resistant to diastase digestion.The pathological diagnosis was LP.Blood samples were collected from all the family members and 100 ethnically matched,unrelated and unaffected Chinese human controls followed by DNA extraction.PCR and sequencing were performed to detect the ECM1 gene,and nested PCR followed by agarose gel electrophoresis to analyze mutations in the coding region of the ECM1 gene.Results Both of the two patients were compound heterozygotes.Three missense mutations,incluing p.P169T,p.A44T and p.R392W,were found in the ECM1 gene of the affected mother,with p.P169T in one allele and p.A44T as well as p.R392W in the other.The girl patient inheried the missence mutation p.P169T from her mother and a synonymous mutation c.879G > A from her father (Ⅱ 1).Nested PCR showed that the c.978G > A mutation generated a splice-acceptor site AG,which leaded to a splicing defect.Conclusion A novel synonymous splice-acceptor site mutation c.879G > A in the ECM1 gene is identified in the family with LP.

Objective To explore the effects of amniotic lacrimal duct stenting on the prevention of dry eye in castrated rabbits.Methods Thirtysix healthy male rabbits were selected,the third eyelid were cut off and antiinfection treatment were given,which were randomly divided into 3 groups (12 cases in each group),the castrated male rabbits models were made.Among them,group A was negative control group,group B was dry eye model group,group C was group of lacrimal amniotic membrane group.At 2 weeks before implantation of amniotic lacrimal duct stent,2 weeks,4 weeks and 6 weeks after implantation,the fluorescent (FL) examination,Western blot,Schirmer I examination,immunofluorescence staining and corneal confocal microscopy were performed.Results The levels of tear secretion and FL in the three groups among different time points were significantly different (F=7.126,P =0.009;F =9.658,P =0.016),and there were significant differences among three groups (F =12.582,P =0.005;F =13.187,P =0.013).The tendency of tear secretion and FL in the three groups were also significantly changed (F =8.531,P =0.007;F =10.652,P =0.019).The epithelial basal cells at 6 weeks after implantation in three groups were 3811 ±414,3820 ± 314,2789 ± 353,and the density of inflammatory cells was 266 ±28,266 ± 29,67 ± 13,there were significant differences among three groups (F =13.442,P =0.012;F =9.231,P =0.021).The K1 6 staining in the duct epithelium were negative,and the expression of α-SMA in the lacrimal duct tissue of group A,B and C was not changed at all time points after implantation of amniotic lacrimal stent,and there was no significant difference (F =14.681,P =0.002).Conclusion The amniotic lacrimal stent implantation has certain effect on the prevention of dry eye in rabbit.

Objective:
To carry out the 4th round of third-party evaluation on the implementation and effect of the 1st year of the 2nd Phase National Healthcare Improvement Initiative(abbreviated as Initiative)since 2015.
Methods:
The 4th round of the evaluation survey adopted the same methods, organization and execution, and technical roadmap as the former three rounds of evaluations.
Results:
The 4th round of evaluation was carried out from 18 March to 9 April, 2019 at 185 public hospitals in 31 provinces(autonomous regions, municipalities directly under the Central Government)and Xinjiang Production and Construction Corps.Facility survey, health professional survey and patient survey were conducted at each of the sample health facilities. A total of 120 782 valid questionnaires were collected from 144 non-psychiatric health facilities, 16 246 valid questionnaires were obtained from 41 psychiatric health facilities, and 252 cases of outstanding departments/hospitals in healthcare improvement were also collected. The average overall scoring of the 12 dimensions to assess Initiative implementation at 144 non-psychiatric health facilities was 84.4%. The overall outpatient satisfaction scoring was 91.1%, 96.7%for the inpatients. The overall inpatient satisfaction(family members inclusive) at 41 psychiatric health facilities was 93%. Areas remaining to be improved include day-surgery, telemedicine and medical social work. Compared with technical services, non-technical care should be further strengthened. The compensation, workload and work environment of the healthcare providers are still to be improved.
Conclusions
The implementation of the Initiative by health facilities has been greatly improved. The percentage of health facilities and patients who had positive perceptions of improved doctor-patient relationship has been increasing. Patient care experiences at public hospitals have been generally improved, and the implementation of promoting traditional Chinese Medicine practices also made progress. However, work satisfaction of healthcare providers was found to be rather low, compared to the high level of patient satisfaction.

Advances in novel drugs, therapies, and genetic techniques have revolutionized the diagnosis and treatment of cancers, substantially improving cancer patients' prognosis. Although rare tumors account for a non-negligible number, the practice of precision medicine and development of novel therapies are largely hampered by many obstacles. Their low incidence and drastic regional disparities result in the difficulty of informative evidence-based diagnosis and subtyping. Sample exhaustion due to difficulty in diagnosis also leads to a lack of recommended therapeutic strategies in clinical guidelines, insufficient biomarkers for prognosis/efficacy, and inability to identify potential novel therapies in clinical trials. Herein, by reviewing the epidemiological data of Chinese solid tumors and publications defining rare tumors in other areas, we proposed a definition of rare tumor in China, including 515 tumor types with incidences of less than 2.5/100 000 per year. We also summarized the current diagnosis process, treatment recommendations, and global developmental progress of targeted drugs and immunotherapy agents on the status quo. Lastly, we pinpointed the current recommendation chance for patients with rare tumors to be involved in a clinical trial by NCCN. With this informative report, we aimed to raise awareness on the importance of rare tumor investigations and guarantee a bright future for rare tumor patients.
