1.Transcrestal sinus floor elevation with the presence of pseudocyst:A clinical study
Journal of Practical Stomatology 2015;(1):44-47
Objective:To evaluate the clinical outcome of transcrestal maxillary sinus floor elevation(TMSFE)in the presence of pseudocyst.Methods:14 cases with pseudocyst were treated by TMSFE.In the operation following osteotome,pseudocyst was not ex-cised and sinus floor membrane was elevated,15 implants were placed for the 14 cases.Definite prosthesis was delivered about 6 months after implant placement.CBCT examination was done before,immediately after and 1-year after surgery,the cyst condition, the gain of vertical bone height and implant stability over time were observed.Results:Pre-operation residual ridge height of the alveo-lar crest was (6.85 ±1.07)mm.The sinus membrane was successfully elevated in all sites without perforation (mean elevation height,6.93 ±2.07)mm.All 15 implants were ossteointegrated.At 1-year revisit the gained bone height was (12.76 ±2.03)mm. Cyst grew bigger in 3 cases,not changed in 3 cases,became smaller in 5 cases and disappeared in 3 cases.Conclusion:Pseudocyst excision is not necessary in TMSFE.
2.Mechanisms involved in liver metastasis of breast cancer
Practical Oncology Journal 2017;31(1):48-52
Liver is the common metastatic site of breast cancer .The process of liver metastasis consists of multiple steps and involves various factors from breast cancer cells and the liver micro -environment .In this re-view,we reviewed the molecular(including the connection of proteins ,protein kinases,miRNAs),signal transduc-tion pathways(including CXCL12-CXCR4 axis,Wnt/beta-catenin signaling pathway,AF1q/TCF7/CD44 regu-latory axis,laminin receptor/Akt/ERK signaling pathway,leptin/ERK/IL-8 signaling pathway)and the influen-cing factors(including hypoxia inducible factors,tumor-associated fibroblasts,adipose tissue matrix stem cells, metalloproteinases,selective ligands,inflammatory cell infiltration)associated with the liver micro -environment in breast cancer .
3.Biological characteristics and molecular biology research hotspots of extranodal NK/T-cell lymphoma,nasal type
Journal of Leukemia & Lymphoma 2012;21(1):19-25
Extranodal NK/T-Cell lymphoma,nasal Type (NKTL) is an individual type in the World Health Organization (WHO) classification.The reports for NKTL are relatively uncommon since the incidence of this disease is low. In recent years, the nude mice model and cell lines of NKTL were established which built up the basis of researches in molecular biology. The investigation are carried out in molecular genetic analysis of lymphoproliferative disorders,tumor microenvironment,and target therapy and so on.We reviewed those advances and concentrated on the development of NKTL molecular biology.

Objective To review the recent advances in the use of marginal liver in liver transplantation. Methods The literatures of recent years on the use of marginal liver for liver transplantation were reviewed and summarized. Results The donors with older age, hemodynamic instability, long stay in the intensive care unit and fatty liver are significantly clinical marginal liver donors. Conclusion Though the use of marginal liver donors negatively influences the results of liver transplantation, marginal liver expands the liver source for liver transplantation with a good result.
5.Progress on Research of Ecological Sanitation System in Rural Area
Journal of Environment and Health 1992;0(04):-
With the fast social and economic development ecosystem has been seriously impacted. Country ecotypic sanitary system based on urine diverting Ecosan toilets and biogas Ecosan toilets can make positive contributions to the protection of ecosystem. This paper makes a review on the conception of ecotypic sanitary system the application of two types of ecotypic utilities the effect of ecotyptic sanitary utility and disease prevention and control comprehensive benefit of country ecotypic sanitary system and construction and operations. The results of researches demonstrate that although some valuable achievements have been gained in those fields mentioned above further improvement should be made and the application should be further widened as soon as possible.

Objective To confirm clinical curative effect and pharmacodynamics mechanism of Clean Lung Conquer Acne Decoction in treating lung-heat type acne,as well as its effect on androgen(andrusol). Methods 80 cases of acne were divided into two groups randomly. Treatment group(50 cases) took orally Clean Lung Conquer Acne Decoction,control group(30 cases) took orally Yiqing capsule,8 weeks was a course of treatment. Clinical therapeutic effect and serum andrusol were observed. Results To lung-heat type acne patient,skin damage effective of treatment group compared with control group,P
7.Peptide retention prediction algorithm and its application in proteomics
Journal of China Pharmaceutical University 2021;52(4):422-430
Most of the proteomics analysis methods based on tandem mass spectrometry rely on the matching scoring of actual spectrum and theoretical spectrum, the interference of a large number of co-eluting peptides could cause error in the identification and quantification of peptides and proteins. Peptide retention time prediction, as a auxiliary and verification index of the peptide, can transition the chromatographic behavior into stable independent time attributes, and improve the accuracy of the peptide identification. Prediction of peptide chromatographic retention in complex systems is also of great significance for optimizing proteomics determination conditions and improving the detection rate and repeatability of mass spectrometry data in data-independent acquisition. This review focused on the chromatographic retention prediction method of unmodified peptides and modified peptides, summarizes the content, characteristics and limitations of four types of peptide retention time prediction methods based on standardized indexes, peptide molecular models, amino acid residue parameters, and machine learning, as well as their applications in proteomics, with a prospect of their future.

Objective To study mental state of children with asthma and psychosomatic symptoms of their parents. Methods Eysenck Personality Questionnaire(EPQ) for children and Rutter's Behavior Ques-tionnaire were applied to 36children aged 6~14with asthma, SCL-90 was applied to their parents. Children from the same kindergartens and schools and their parents were sampled as control matched by age, sex etc.Results Children with asthma had more personality problems than normal children. The E.N scores of EPQ scales were higher in asthma children than in normal samples. The rate ot behavior problems was 33.3 %; Par-ents of children with asthma had higher scores of S SCL-90 than parents of children as control, espeeially in de-pression, anxiety, somatic complaints and terror. Conclusion Children with asthma and their parents, It is im-portant to take some active measures to intervene psychological and behavioral problems of children with asth-ma and psychosomatic symptoms of their parents.

Objective To study the relationship between sICAM 1,sVCAM 1,TNF ?,TNFR Ⅰ,TNFR Ⅱ and pathogenesis of vasculitis.Method The serum levels of TNF ?,TNFR Ⅰ,TNFR Ⅱ,sICAM 1 and sVCAM 1 were detected by ELISA and their levels between patients with vasculitis and controls were compared.Results Compared with the controls,the serum level of TNF ? was lower,the levels of TNFR Ⅰ,sICAM 1 and sVCAM 1 were higher in the patients with vasculitis,and there was no difference of TNFR Ⅱ between the two groups.Conclusion The low level of TNF ? suggests that this factor may not play a role in these patients,or its role was counteracted by its receptors—sTNFR,whose level was higher in patients with vasculitis.sICAM 1 and sVCAM 1 may play a significant role in the pathogenesis of vasculitis.
