2.Assessment methods and research progress of blood glucose variability
Chinese Journal of Endocrinology and Metabolism 2010;26(3):261-264
Recently,basic and clinical researches have shown that blood glucose variability is an independent risk factor for diabetic complications.Thus,ideal control of blood glucose is not only to reach the HbA1Ctarget,but also to minimize blood glucose variability.Different glycemic parameters could be selectedaccording to different purpose of evaluation,in which the mean amplitude of glucose excursions(MAGE) and the standard deviation of blood glucose (SDBG) could be used as accurate and simple assessment parameters respectively.
3.Diagnosis and therapy for POEMS syndrome
Chinese Journal of Clinical Oncology 2014;(13):831-835
POEMS syndrome is a rare clonal plasma cell disease characterized by polyneuropathy, organomegaly, endocrinopathy, M protein, and skin changes. Significant advances have been made in the diagnosis and treatment of POEMS syndrome over the last decade. In this study, we reviewed the diagnostic criteria and characteristic features of POEMS syndrome. We also focused on the role of the characteristic features of POEMS syndrome in early diagnosis. Autologous peripheral blood stem cell transplantation has become the first-line treatment for younger patients with normal organ function because it has resulted in a high response rate and durable remission. Melphalan and dexamethasone is an effective and well-tolerated treatment for older patients and those with organ dysfunction. Patients with poor performance status or renal function can benefit from novel agents that can also improve transplantation eligibility.
4.Intrauterine vertical transmission of HBV via pathway of peripheral blood mono-nuclear cells
Chinese Journal of Immunology 2014;(7):946-949
Objective:To study the HBV infection in peripheral blood mononuclear cells in mediating the role of mother -to-child transmission of hepatitis B virus.Methods: The peripheral blood mononuclear cells ( PBMCs ) in maternal and cord blood mononuclear cells ( CBMCs ) in newborns were conventionally isolated by Ficoll-Hypaque medium.The loads of HBV-DNA in peripheral blood of maternal and cord blood of newborns were both detected by PCR .Results:The clinical data showed that the positive detection rates of HBV-DNA in serum and PBMCs of pregnant women with HBeAg (+) were 100.00%( 25/25 ) and 72.00%( 18/25),and the positive detection rates of HBV-DNA in the neonatal umbilical cord blood serum and CBMCs were 60.00%(15/25) and 44.00%(11/25),respectively.There were significantly difference between HBeAg (+) and HBeAg(-) in the pregnant women (P<0.05 ).The positive detection rates of HBV-DNA in neonatal umbilical cord blood serum and CBMCs were higher in the group with high HBV loads (more than 106copies/ml) in PBMCs than those of low HBV loading group (102-103copies/ml).The significantly difference was explored between the two groups.Conclusion: Mononuclear cells can not only be infected by HBV , but also play a critical role in the intrauterine vertical transmission of HBV via the pathway transmitted from PBMCs in pregnant women to CBMCs in newborns.

Chinese Journal of Hepatobiliary Surgery 2015;21(2):117-121
Objective To evaluate the risk factors of gallstone occurrence after gastrectomy for gastric cancer.Methods Relevant documents published from 1990 to 2014 were retrieved through Pubmed,Cochrane Library,Embase,Web of Science CNKI,Wan Fang and VIP databases search.The Meta-analysis was applied with RevMan 5.3 software for Odds ratio and 95% CI.Results 24 studies were selected for this Meta-analysis which included 3 randomized controlled trials,13 cohort studies and 8 case-controlled studies.These 24 studies included patient number which ranged from 32 to 893.The pooled OR (95% CI) and P values of OR (95 % CI) for physiologic digestive tract reconstruction were 0.53 (0.44 ~ 0.65,P < 0.05) ;amount of resection of stomach,1.98 (1.29 ~ 3.04,P < 0.05) ; lymphadenectomy,0.38 (0.21 ~ 0.72,P < 0.05) ; vagotomy,0.24 (0.13 ~ 0.45,P < 0.05) ; and pylorus preservation,0.70 (0.48 ~ 1.02,P > 0.05).Conclusions Physiologic digestive tract reconstruction and vagus nerve preservation reduced occurrence of gallstones after gastrectomy.On the other hand,total gastrectomy and extensive lymph node dissection increased the occurrence.There was no significant difference in the occurrence of gallstones whether there was pylorus preservation or not.
6.Effect of Oleanic Acid on Key Enzyme Activity in Insulin-Resistant HepG2 Cell Line
Herald of Medicine 2015;(9):1139-1141
Objective To explore the effect of oleanic acid on key enzyme activity in insulin-resistant HepG2 cells. Methods The HepG2 cells were divided into normal control,model control,metformin,and oleanic acid groups.Glycogen content in insulin-resistant HepG2 cell model were detected by hepatic glycogen test kit upon treatment with oleanic acid.Activities of glucokinase ( GK) ,phosphoenolpyruvate carboxylase kinase (PEPCK),and glucose-6-phosphatase (G-6-Pase) were assayed by the glucose 6-phosphate dehydrogenase coupling colorimetric, lactate dehydrogenase coupling colorimetric and ammonium molybdate constant phosphorus methods. Results The oleanic acid enhanced glucose consumption,lowered the activity of G-6-Pase and PEPCK by 54.8% and 18.8%,respectively,and increased the activity of GK and glycogen content in also insulin-resistant HepG2 cells by 100.6% and 98.6%,respectively. Conclusion Aqueous extracts of shirako play a role in lowering PEPCK and G-6-Pase activities and inhibiting glucogenesis, resulting in the reduction of endogenous glucose in the cell. In addition,it can augment the activity of GK,accelerate the process of glucolysis,increase the glycogen content,and alleviate insulin resistance of HepG2.
7.Application of Pentacam in the cataract surgery
International Eye Science 2015;(8):1358-1362
With the improvement of cataract operation, the cataract surgery has become increasingly perfect. The cataract patients show greater expectation for the result of cataract operation. As a result, refractive cataract surgery has become the main trend. Detailed investigations of corneal diseases, lens density, corneal topography, preferable intraocular lens ( IOL ) choice, and IOL power calculation can help us get a better knowledge of preoperative conditions on patients, which can be conducted with pentacam. So we can have a better forecast of post - operative outcome and improve the quality of vision for cataract patients after surgery.
8.Detection of DNA aneuploidy in exfoliated airway epithelia cells of sputum specimens by the automated image cytometry and its clinical value in the identification of lung cancer.
Journal of Huazhong University of Science and Technology (Medical Sciences) 2004;24(4):407-10
To evaluate the value of detection of DNA aneuploidy in exfoliated airway epithelia cells of sputum specimens by the automated image cytometry for the identification of lung cancer, 100 patients were divided into patient group (50 patients with lung cancer) and control group (30 patients with tuberculosis and 20 healthy people). Sputum was obtained for the quantitative analysis of DNA content of exfoliated airway epithelial cells with the automated image cytometry, together with the examinations of brush cytology and conventional sputum cytology. Our results showed that DNA aneuploidy (DI>2.5 or 5c) was found in 20 out of 50 sputum samples of lung cancer, 1 out of 30 sputum samples from tuberculosis patients, and none of 20 sputum samples from healthy people. The positive rates of conventional sputum cytology and brush cytology were 16% and 32%, which was lower than that of DNA aneuploidy detection by the automated image cytometry (P<0.01, P>0.05). Our study showed-that automated image cytometry, which uses DNA aneuploidy as a marker for tumor, can detect the malignant cells in sputum samples of lung cancer and it is a sensitive and specific method serving as a complement for the diagnosis of lung cancer.

9.Clinical application value of whole-brain CTA-CTP imaging in cerebral arteriovenous malformation
Journal of Practical Radiology 2016;32(12):1834-1837
Objective To explore the clinical application value of whole-brain CTA-CTP imaging in cerebral arteriovenous malformation (cAVM).Methods Fifteen patients diagnosed with cAVM by CTA-CTP imaging were included in this retrospective analysis study. The angioarchitecture of cAVM lesions were recorded from 4D-CTA images.Using DSA as the golden standard,the diagnostic accuracy of 4D-CTA was evaluated in 13 cases.The perfusion patterns of vessel nidus and peritumoral tissues were analyzed from the CTP images.Bleeding ratios of patients with different angioarchitecture and perfusion patterns were compared.Results 4D-CTA could dynamically display the angioarchitecture details of cAVM lesions and show the whole process of the contrast agent in and out of the vessel nidus.Although the result of 4D-CTA was consistent with that of DSA in most cases,a few fine feeding arteries and draining veins were missed.The nidus in thirteen cases was with high perfusion and the peritumoral tissues were with low perfusion.Another two cases were with low perfusion due to the presence of hematoma.Nine cAVMs suffered from small size,single feeding artery,deep venous drainage and vessel nidus with increased MTT,peritumoral tissues with decreased MTT were more likely to suffer a hemorrhage (P<0.05).Conclusion Whole-brain CTA-CTP imaging could be a valuable adjunct in noninvasive diagnosis of cAVM and predicting the bleeding risk factors.
10.Polysaccharidical peptides augmented the functions of tumour infiltrating lymphocytes
Chinese Journal of Pathophysiology 1986;0(02):-
The effects of polysaccharidical peptides (PSP) on the functions of tumour infiltrating lymphocytes (TILs) in vitro was explored. The results showed that PSP, at the concentration of 37-1200?g/ml, promoted the proliferation of TILs in dose-related manner. Combination of PSP with interleukin-2 (IL-2) enhanced the cytotoxicity of TILs and reduced the dose of IL-2 used for activating TILs. The results suggested that PSP could augment the proliferation and cytotoxicity of TILs in vitro.
