OBJECTIVETo explore therapeutic effect of absorbable net-sliding intertexture with tension band wiring in treating comminuted fracture of distal patella pole.
METHODSFrom January 2012 to December 2016, 80 patients with comminuted fracture of distal patella pole were treated with absorbable net-sliding intertexture with tension band wiring, including 45 males and 35 females aged from 25 to 60 years old with an average of(45.0±2.0) years old. All fractures were freshly closed. VAS scores and motion of knee joint were evaluated at 6 weeks after operation, HSS scores were used to assess clinical effects at 12 months after operation.
RESULTSOperative time was (50.2±10.1) min, blood loss was (20.3±5.2 ) ml. All patients were followed up from 12 to 24 months with an average of (16.0±0.5) months. VAS score was 1.8±0.4, range motion of knee joint was (120.6±1.5)° at 6 weeks after operation. The fracture healing time was (3.0±0.8) months. Postoperative HSS score at 12 months was 95.6±0.6.
CONCLUSIONSAbsorbable net-sliding intertexture with tension band wiring in treating comminuted fracture of distal patella pole has advantages of simple operation, stable fixation, which could recover anatomical formation of patella, obtain rapid rehabilitation and favorable prognosis with early exercise. It is an ideal method for treating comminuted fracture of distal patella pole.

Paeoniflorin and its derivatives are main active compounds inGui-Zhi Fu-Ling Capsule (GZFLC). In this study, molecular imprinted polymer (MIP) was prepared by sol-gel process to obtain paeoniflorin and its derivatives in GZFLC. The static adsorption capacity of MIP was measured by scatchard equation. The results showed that the maximum apparent absorbing capacity of MIP was 52.28 mg·g-1. One-step separation of paeoniflorin from 4 g methanol samples of GZFLC was 197 mg with the purity of 89.3%. It was concluded that paeoniflorin MIP can be used to separate phaoniforin and its analogues from GZFLC.

OBJECTIVE:
To screen the differential expression of apoptosis-related protein and stress response protein(APR-SRP) genes after human brain injury by cDNA microrarray.
METHODS:
The total RNAs were isolated from normal and injured brain tissues of a car-accident victim, and were purified to obtain mRNAs by Oligotex. Both mRNAs from the tissues of the injured and the normal tissue were reversely transcribed to cDNAs with the incorporation of fluorescent dUTP to prepare the hybridization probes. The probes from normal tissue was labeled with Cy3-dUTP, that from the injured tissue with Cy5-dUTP. The mixed probes were hybridized to the BioDoor Chip ARP-SRP-1.0S, a cDNA microarray which contains 77 apoptosis related protein genes and 23 stress protein related genes. After high-stringent washing, the cDNA microarray was scanned for the fluorescent signals and showed differences between two tissues.
RESULTS:
Among the 100 target genes, Only CLN2 gene (Homo sapiens lysosomal pepstatin insensitive protease gene) showed distinct deference in expression level between the brain injury and normal tissues.
CONCLUSION
cDNA microarray analysis indicated that CLN2 gene, which is correlated to a fatal childhood neurodegenerative disease, might be related to the brain injury. The expression level of CLN2 gene was significantly decreased in brain injured tissue in comparison to normal tissue. Further analysis of this gene will be helpful to understand the molecular mechanism of brain injury and utilization in forensic medicine.

OBJECTIVE:
To screen the differential expression of oncogenes and tumors suppressed genes(OTS genes) after human brain contusion by cDNA microrarray.
METHODS:
The total RNAs isolated from normal and contusion human brain tissues were purified by Oligotex to obtain mRNAs. Both sources of mRNAs were reversely transcribed to cDNAs with the incorporation of fluorescent dUTP to prepare the hybridization probes. The probe from normal tissue and the contusion brain tissue were labeled with Cy3-dUTP and Cy5-dUTP respectively. The mixed probes were hybridized to the BioDoor Chip OTS-2.2S, a cDNA microarray which contains 227 oncogenes and tumors suppressed genes. After high-stringent washing, the cDNA microarray was scanned for the fluorescent signals and showed differences between two tissues.
RESULTS:
Among the 227 target genes, 3 genes including Human carcinoma associated HOJ-1 (HoJ-1), Human KIAAOO65 gene,Human retinoblastoma related protein (p107) gene, showed distinct deference in expression level between the human brain contusion tissue and normal tissue.
CONCLUSION
The 3 genes in the brain contusion was significantly the differential expression by OTS 2.2S cDNA microarray. Further analysis of these genes will be helpful to understand the molecular mechanism of brain injury and utilization in forensic medicine.

OBJECTIVETo evaluate the level of serum carbohydrate antigen-125(CA125) and its related factors in patients with bronchiectasis.
METHODSThe clinical data of 504 patients with bronchiectasis in Zhejiang Putuo People's Hospital from June 2009 to June 2014 were collected in the study.The patients were divided into CA125 elevated group and CA125 normal group according to serum CA125 level,and the differences of serum CA125,age,gender, white blood cell(WBC),C-reactive protein(CRP), blood glucose and other test indicators were compared between two groups.
RESULTSThere were 276 patients including 117 male and 159 female with elevated serum CA125.Their mean age was(66.3±13.1)years and the mean level of CA125 was(83.70±43.87) U/mL. There were 228 patients including 84 male and 144 female with normal CA125 levels. Their mean age was(67.5±10.5) years and the mean level of CA125 was(20.68±9.67)U/mL.The peripheral blood WBC in patients with CA125 elevated group[(10.08±5.68)×10(9)/L] was significantly higher than that in CA125 normal group[7.73±3.46)×10(9)/L], the difference was statistically significant(P<0.05).The medium of CRP level in patients with CA125 elevated group[22.98(3.18~196.88)mg/L] was significantly higher than that in CA125 normal group[6.34(0.50~97.66)mg/L](P<0.05). Correlation analysis showed that CA125 was positively correlated with WBC and CRP(P<0.05). Stepwise regression analysis showed that CRP was the only independent prognostic factors of CA125. Paired t test showed the presence of CA125 serum in patients with bronchiectasis had a significant difference between before and after anti-infection therapy(P<0.05).
CONCLUSIONThe serum levels of CA125 rise in patients with bronchiectasis,while it decrease after anti-infection therapy.CRP is an independent associated factor of serum CA125 level.

In recent years, the rapid development of digital intelligence has provided a new path for rare disease data sharing and injected new power into the progress of research of rare diseases. This research is aimed at summarizing and consolidating relevant literatures on data sharing driven by digital intelligence (DI) in China and abroad, and constructing a local theoretical framework of DI-driven data sharing for rare diseases based on the status of rare diseases in China. Searching PubMed, EMbase, Cochrane, CNKI, Wanfang, and VIP database, we obtain a total of 214 representative literatures. Through literature review, we find that DI technologies have played important roles in different aspects of rare disease data sharing. China, the United States, and Europe have formed their own DI-driven data sharing systems for rare disease. From the theory of " Information Commons", we analyze the gap between China′s current situation and the goal of a " Rare Disease Data Commons". Based on the analysis, we put forward the idea of framework of " DI-STARS". China should develop the Data Sharing system making DI as the core of the system. Meanwhile, China should strengthen the data standardization system, create an innovation-encouraging environment, and build a bridge between different platforms. Using the DI-STARS theory, China will be able to build the " Rare Disease Data Commons" so that the diagnosis and treatment of rare diseases will be enhanced in China to meet the patients′ needs.
