[Objective]To evaluate several abdominal skin flaps used for treatment of whole-finger degloving injury of multiple fingers.[Method]Since 2000, 45 patients with whole-finger degloving injury of multiple fingers except the thumb were treated with transfer of abdominal skin flaps. Among these patients,10 were treated with random abdominal tubed pattern flaps,15 with pedicle skin flaps with thoraco-umbilical perforator artery,12 with pedicle skin flaps with superficial iliaccircumflex artery,and 8 with embedding with abdominal flaps.At the second-stage operation,fingers were dissected with pedicels or with abdominal flaps before fingerweb plasty and flap plasty were carried out for many times.[Result]All the skin flaps survived. Three fingers of 3 cases had distal cutaneous necrosis after finger web plasty.Follow-up from 5 to 36 months showed the active motion of metacarpophalangeal joints averaged 60?, and interphalangeal articulations averaged 30?.Sensation recovery reached S3 in fingers with remanent palmar digital nerve, but poor in other fingers. All fingers could perform grasping. The contour of fingers was fine except for the 3 cases of necrosis.[Conclusion]Treatment of whole-finger degloving injury of multiple fingers except the thumb with suitable abdominal flaps can restore the shape and function of hand to the greatest extent and is still a practical, safe and convenient operative method.
4.Expressions of TFF1 and TFF3 in prostate cancer and prostatic intraepithelial neoplasia and their clinical significance.
National Journal of Andrology 2015;21(4):315-319
OBJECTIVETo explore the expressions of trefoil factor 1 (TFF1) and trefoil factor 3 (TFF3) in prostate cancer (PCa) and prostate intraepithelial neoplasia (PIN) and their clinical significance.
METHODSUsing immunohistochemistry, we detected the expressions of TFF1 and TFF3 in the prostatic tissues of 89 cases of PCa, 50 cases of PIN, and 65 cases of benign prostate hyperplasia (BPH), and evaluated their clinical significance.
RESULTSThe positive rates of TFF1 and TFF3 expressions were 77. 53% and 48. 31% in PCa and 66.00% and 30.00% in PIN, significantly higher than 49.23% and 13. 85% in BPH (P <0. 05). The expression of TFF1 was not correlated with Gleason score (P >0. 05), while that of TFF3 was significantly higher in the PCa cases with Gleason score ≤7 than in those with Gleason score > 7 (70. 00% vs 42. 03%, P <0. 05). No significant correlation was observed between TFF1 and TFF3 expressions in PCa (P >0. 05).
CONCLUSIONThe expressions of TFF1 and TFF3 may contribute to the occurrence and progression of PCa, and therefore could be used as laboratory indexes in the diagnosis, differential diagnosis, and prognosis of PCa.

5.Mutual information-based correlation analysis of herbs against insomnia.
China Journal of Chinese Materia Medica 2015;40(19):3873-3877
This paper aims to analyze Professor Guo Rongjuan's medication experience on insomnia therapy based on the Traditional Chinese Medicine (TCM) Inheritance Support Plat. First, TCM formulae prescribed by Professor Guo for insomnia therapy were collected from the TCM Inheritance Support Plat. Next, unsupervised data mining algorithms, including apriori, modified mutual-information, and entropy clustering of complex system were applied to obtain the frequencies for different herbs and identify the association rules among the herbs. Accordingly, we can gain new insights into Professor Guo's medication experience on insomnia therapy. Based on analysis of 3 084 formulae, we determined the frequencies for herbs in the formulae and identified the association rules among these herbs. At last, 41 core combinations and 7 new formulae were obtained. The identified medication experience conform with Professor Guo's views on the etiology and pathogenesis of insomnia: "pathogenic fire derived from stagnation of liver-QI (Gan Yu Hua Huo)" is the core pathogenesis of insomnia; "liver stagnation and spleen deficiency" and "chronic illness transferred to kidney" are the main features for insomnia. The TCM Inheritance Support Plat is of great practical value for mining clinical experience of famous TCM doctors.

6. Effects of imatinib on the expression of SHIP gene and apoptosis of K562 cells
Tumor 2007;27(11):853-856
Objective: To observe the changes of SHIP, caspase-1, caspase-3, caspase-9 and bcl-2 gene expression levels in K562 cells after mesylate imatinib (MI) treatment and explore the possible mechanism for apoptosis-inducing effects of imatinib. Methods: K562 cells were cultured with MI at different concentrations. The cells were collected at different time points. Real-time quantitative PCR was used to detect the expression level of SHIP gene. Semi-quantitative reverse transcriptase PCR was used to detect the mRNA transcription of anti-apoptotic gene bcl-2 and pro-apoptotic genes caspase-1, caspase-3 and caspase-9. The cell proliferation was measured by MTT assay. The cell apoptosis was analyzed by Annexin V/PI double staining flow cytometry. Results: MI significantly increased the expression of SHIP gene in a time-and dose-dependent manner. Caspase-9 gene was also up-regulated after MI treatment and had linear correlation with SHIP gene expression. The expression levels of caspase-1, caspase-3 and bcl-2 had no significant changes. MI down-regulated the proliferation and induced the apoptosis of K562 cells. The morphological changes of typical of apoptosis were observed. Conclusion: MI significantly increases the expressions of SHIP gene and caspase-9 gene and induces apoptosis of K562 cells. The mechanism for the apoptosis-inducing effects of imatinib may be associated with the up-regulation of SHIP and caspase-9 gene.

Journal of Preventive Medicine 2020;32(12):1204-1207
Objective:
To develop the ultra performance liquid chromatography tandem mass spectrometry ( UPLC-MS/MS ) for the determination of perfluorocarboxylic acids ( PFCAs ) in fish.
Methods:
The fish samples were extracted with tert-butyl methyl ether and purified by WAX columns. The WAX cartridges were rinsed with methanol and 25 mmol/L ammonium acetate, and the target compound residues were eluted with 0.5% ammonia methanol and then redissolved with 50% methanol aqueous solution after nitrogen blowing to nearly dry. Nine kinds of PFCAs were simultaneously quantified by UPLC-MS/MS with 1 mmol/L ammonium acetate-methanol solution as the mobile phase.
Results:
The extraction was separated well in UPLC BEH C18 column. There were good linear correlations of nine kinds of PFCAs in the range of 1.0-200.0 ng/mL, with the coefficients all more than 0.99. The limits of detection and quantification were 0.06-0.19 μg/kg and 0.19-0.62 μg/kg, respectively. The recovery rates were 70.08%-117.24% at different spiked levels ( 5.0, 25.0, 50.0 μg/kg ), and the relative standard deviations were 2.31%-19.68%.
Conclusion
Through optimizing the pretreatment conditions, the mobile phase of liquid chromatography and the detection conditions of mass spectrometry, the UPLC-MS/MS could meet the monitoring requirements of PFCAs in fish.

Drug-induced nephrotoxicity is very common in both new drug development and clinic practice. Various drugs can induce kidney injuries, including tubulointerstitial, glomerular and renal vascular disease. To investigate the mechanism of drug induced nephrotoxicity is important for risk reduction of new drug development, reasonable drug usage, early discovery and effective prevention/treatment of adverse effects in clinics.
10.Expression of the epithelial cell adhesion molecule in prostate cancer and its clinical significance.
National Journal of Andrology 2015;21(4):320-324
OBJECTIVETo explore the expression of the epithelial cell adhesion molecule (EpCAM) in prostate cancer (PCa) and its clinical significance.
METHODSWe collected tissue samples from 63 cases of PCa, 46 cases of prostatic intraepithelial neoplasia (PIN), and 58 cases of benign prostatic hyperplasia (BPH) adjacent to PCa and determined the expression of EpCAM in the epithelial and stromal cells by immunohistochemistry.
RESULTSThe positive expression rates of EpCAM in the epithelial cells were significantly higher in PCa and PIN than in PCa-adjacent BPH (98. 4 and 97. 8 vs 51.7%, P <0. 01), and so was that in the stromal cells of PCa than in those of PCa-adjacent PIN (89.5 vs 50.0%, P <0.01). The expression of EpCAM.was remarkably higher in the stromal cells of bone metastasis than in those of non-bone metastasis tissue (100. 0 vs 40. 0%, P <0. 01) but showed no statistically significant differences between the highly and poorly differentiated PCa tissues (88.5 vs 91.9%, P >0.05).
CONCLUSIONThe expression level of EpCAM in the stromal cells of PCa is related to the occurrence, progression, and bone metastasis of the tumor, and therefore may be used as a marker in the early diagnosis of PCa as well as a predictor of bone metastasis of the tumor.
