1.Study on antiviral effect of indole-2,3-dine
Chinese Journal of Marine Drugs 1994;0(04):-
Objective To investigate antiviral and immunoregulation effects of indole-2,3-dine(ISA).Methods The BHK-21 cell model infected with Sendai virus was established and the antiviral effect of ISA was observed by cytopathic effect(CPE) method;its effect on immunological function was observed by hemagglutination inhibition test using Sendai virus infected mice model.Results ISA showed cytotoxicity when the concentration was above(0.313)mg?mL~(-1),while ISA showed a dose-dependent antiviral effect without cytotoxicity when the concentration was among 0.156~0.039mg?mL~(-1).ISA at higher dose(2%) could accelerate the production of hemagglutination inhibition antibody in hemagglutination test(P
3.Current Development of Breast-Specific Gamma Imaging (BSGI) Technique.
Chinese Journal of Medical Instrumentation 2015;39(2):108-112
Breast-Specific Gamma Imaging (BSGI) is an improved and optimizing nuclear medicine breast imaging technique on the basis of traditional gamma camera. It uses a high resolution, small field-of-view scintilla detector. The detector is designed with 3 073 individual detector crystals and 48 position-sensitive photomultiplier tubes. The FOV of detector is 15 cm x 20 cm, and optimal system resolution for breast imaging is 3 mm, can detect the diameter of only 2-3 mm small lesions. BSGI has better sensitivity in detecting subcentimetre or nonpalpable breast cancer. The sensitivity for the diagnosis of breast cancer is high, not influenced by the density of the breast tissue, implants, architectural distortion-or scars from prior surgery or radiation. So it is called a high resolution, small field-of-view breast-specific gamma camera.

4.Long noncoding RNA EPB41L4A-AS2 associated with the prognosis of tumors
Practical Oncology Journal 2017;31(3):205-210
Objective The relationship between the clinicopathological features and the prognosis of breast cancer patients was evaluated by the expression of EPB41L4A-AS2 in breast cancer tissues.Methods The relationship between the expression of EPB41L4A-AS2 and the clinical features of breast cancer was evaluated by using the genome meta analysis,TCGA and Gene Expression Library(GEO) datasets.The correlation between EPB41L4A-AS2 and apoptotic pathway was verified by Western blotting.Results The results from Meta -analysis,TCGA and GEO datasets showed that EPB41L4A-AS2 was low in breast cancer tissues and was positively correlated with poor clinical and pathological features.EPB41L4A-AS2 was confirmed an association with the classical apoptosis pathway in breast cancer cell lines.In the meta-analysis of GEO,we found the high expression of EPB41L4A-AS2 with good prognosis.Conclusion EPB41L4A-AS2 inhibits tumor formation and has a high value in clinical prognosis of breast cancer.

Objective: To design a convenient and safe leg support of lithotomy position surgical bed. Methods:Put the gas spring in the device to lift and drop the leg support, instead of turning screw, And then use the new leg support in 80 lithotomy position surgeries. Results:The new device can be operated by one man, it is easy operating and labor saving. There was no leg slip occurred in 80 surgeries, operators all expressed satisfaction. Conclusion: This innovation patent solved the problem of toilsome operating and potential safety hazard, It worth widely use in the clinical.

Obiective To realize real-time data processing in lung ventilation reconstruction based on electrical impedance tomography(EIT). Methods The image reconstruction algorithms, plotting functions and matrix calculations are dynamic transferred with Matlab C++, Mathtools and VC++ to meet the requirements of data processing and imaging in real time.Results Image reconstruction and real-time data processing were realized successfully in lung ventilation based on EIT. Conclusion It provides a new strategy for real-time data processing of image reconstruction by EIT.
8.Comparison of different operation methods for the treatment of localized and high risk prostate cancer
Chinese Journal of Urology 2014;35(9):672-675
Objective To compare clinical efficacy and complications of three operation methods for treating the localized and high risk prostate cancer.Methods From July 2006 to July 2010,102 cases with localized and high risk prostate cancer were included in the study.Among them,51 cases received open radical prostatectomy (Group A).Their characters included aged (63.7±7.9),PSA (31.8±6.6) μg/L,Gleason scores (8.5±0.5).In this group,T2c stage was diagnosed in 38 cases and T3a stage in 13 cases.32 cases received laparoscopic radical prostatectomy(Group B).Their characters included aged (64.4± 8.3),PSA (29.9±5.2) μg/L,Glcason scores (8.7±0.4).In this group,T2c stage was diagnosed in 21 cases and T3a stage in 11 cases.19 cases received 125I implantation (Group C).Their characters included aged (61.4± 7.4),PSA (30.6±.5.7)μg/L,Gleason scores (8.6±0.6).T2v stage was found in 8 cases and T3a stage in 11 cases.Operation time,amount of bleeding,hospitalization time,drainage time,gastrointestinal function recovery time,medical expenses and survival and recurrence rate in 1 year,3 years,5 years were compared within those groups.Results Operation time in three group were (232.6±38.4) min,(186.3±31.4) min,(35.4±14.6) min,respectively.Amount of bleeding in three group were (413.6±132.4) ml,(273.9± 77.4) ml,(19.4±4.4) ml,respectively.Hospitalization time in three group were (20.9±3.7) d,(15.6± 2.2) d,(6.4±2.6) d respectively.Drainage time in three group were (8.3±1.8) d,(7.5±0.9) d,(3.2± 0.8) d,respectively.Gastrointestinal function recovery time in three group were (4.1 ±0.6) d,(3.2± 0.4) d,(0.4±0.1) d,respectively.Medical expenses in three group were (23±4) thousand yuan,(32±3) thousand yuan,(45t3) thousand yuan respectively.All those items exhibited the significantly statistical difference (P<0.05).The survival and recurrence rates had no significant difference during the follow-up in three groups.Conciusions Compared to the open radical prostectomy and laparoscopic radical prostectomy,particle implantation for prostate cancer had advantages in minimally invasive,less bleeding,short operation time,fast recovery and protection for Intestinal function.

OBJECTIVE:To observe the clinical efficacy and ADR of Fuzheng huaji pills in the adjunctive treatment of mid-dle and advanced primary liver cancer. METHODS:122 patients with middle and advanced primary liver cancer who had lost the chance or were unwilling to accept surgery,radiotherapy or chemotherapy were randomly divided into control group (61 cases) and study group(61 cases). The control group received conservative treatment such as hepatoprotecives;the study group was treat-ed with Fuzheng huaji pills 1 pills per time,3 times a day,additionally for 30 days. The tumor volume changes,major clinical symptom scores,quality of life,hemorheology indexes and alpha-fetal protein(AFP),lab index and ADR were compared between 2 groups. RESULTS:After treatment,tumor stable rate of study group was 67.2%,the improvement rate of life quality 27.9%, and AFP(563.35±143.17)pg/L;the scores of liver pain,abdominal distension,loss of appetite and fatigue,and plasma viscosity, whole blood viscosity,erythrocyte sedimentation rate decreased greatly,there were significant differences,compared to control group (P<0.05). One patient in study group suffered from diarrhea,and the symptom was relieved after symptomatic treatment;no obvious ADR was found. CONCLUSIONS:Through stabling tumor, improving major clinical symptom, life quality and hemorheology indexes,Fuzheng huaji pills play a synergistic treatment effect on primary liver cancer.
