2.Effects of oxidized HDL on the levels of MCP-1, ICAM-1 and free calcium in cultured human umbilical venous endothelial cells
Chinese Journal of Pathophysiology 2001;17(6):559-562
AIM: To study the effects of oxidized high-density lipoprotein (oxHDL) on the expression of monocyte chemoattractant protein-1(MCP-1) and intercellular adhesion molecule-1(ICAM-1) and intracellular free calcium concentration ([Ca2+]i) level in cultured human umbilical venous endothelial cells(HUVECs). METHODS: The MCP-1 protein content in the medium of conditioned HUVEC was measured by ELISA, and the ICAM-1 on HUVECs was detected by indirect immunofluorescence, and [Ca2+]i was determined by Fluo-3/AM, the injury of cells was observed by scanning electron microscopy (SEM).RESULTS: oxHDL could induce the expression of MCP-1 and ICAM-1 in HUVECs. In oxHDL group (HUVECs were incubated with 100 mg protein/L oxHDL for 24 h), the levels of MCP-1, ICAM-1 and [Ca2+]i increased by 160%, 60% and 70% respectively compared with the control group (P<0.01). When HUVECs were incubated with 300 mg protein/L oxHDL for 24 h, cells were injured obviously. CONCLUSION: By inducing the expression of ICAM-1 and MCP-1 in endothelial cells, oxHDL may promote monocyte-endothelium adhesion and monocyte migration to intima, it may promote atherosclerosis as oxidized low-density lipoprotein (oxLDL).
3.Research progress of hepatic arterial infusion chemotherapy in the conversion therapy of hepatocellular carcinoma
Chinese Journal of Digestive Surgery 2021;20(2):171-177
Primary liver cancer is the fourth most common malignancy and the second most common cause of cancer death in China, posing a serious threat to the health of Chinese people. Hepatocellular carcinoma (HCC) represents more than 90% of primary liver cancers, among them 66% of patients are with intermediate-advanced HCC. Therefore, prevention strategies and conversion therapies to patients with intermediate-advanced HCC are particularly important. Hepatic arterial infusion chemotherapy (HAIC) is one of the important treatment methods to treat intermediate-advanced HCC. The tumor objective response rates and surgery conversion rates of HAIC-based conversion therapies are promising. The authors review the history of HAIC and the HAIC-based conversion therapies in this article.

Chinese Journal of General Practitioners 2017;16(8):602-605
Objective To analyze the clinical characteristics of brucellosis presenting as fever of unknown origin in non-endemic area.Methods Clinical data of 11 patients with fever of unknown origin,who were admitted in a general hospital of non-endemic area from Jan 2013 to Jan 2017 and diagnosed as brucellosis by blood culture,were retrospectively analyzed.Results There were 8 males and 3 females aged 40-70 years.The patients were admitted with or without accompanied symptoms.The patients were initially presented in rheumatology (1 case),neurology (1 case),emergency (4 cases),hematology (1 case),orthopedics (2 cases) and pneumology (2 cases) departments,respectively.The time from onset to presentation was 0.5-7.0 months.The clinical manifestations were nonspecific,and blood cultures of Brucella were positive between 2 to 5 weeks with a mean of 3 weeks.Time to diagnosis was 1 to 9 months with a mean of 4 months.All patients were transferred to infectious hospital when the diagnosis was confirmed.The telephone follow-up showed that none of the patients had fever after discharged.Conclusion Brucellosis should not be neglected in the differential diagnosis of FUO in non-endemic area,and blood culture is important for a definitive diagnosis.
7.New updates of diagnosis and treatment of adenocarcinoma of esophagogastric junction
Chinese Journal of Digestive Surgery 2017;16(5):446-449
The definition,staging and optimal treatment of adenocarcinoma of esophagogastric junction (AEG) have long been in controversy.Surgery is still the primary treatment for resectable AEG,and surgical procedures depend on its classifications.However,the efficacy of surgery alone is barely satisfactory.Neoadjuvant chemoradiotherapy and perioperative chemotherapy can improve the survival of patients.Simplified 2 cm principle is presented in the 8th edition of American Joint Committee on Cancer for TNM staging system of esophageal cancer.In addition,the new edition provides clinical staging and pathologic staging after neoadjuvant therapy,improving the clinical practicability of new staging system.

9.The Cost-Effectiveness Analysis of Irbesartan in the Treatment of Hypertensive Type 2 Diabetic Patients with Microalbuminuria in China
China Pharmacy 1991;0(03):-
OBJECTIVE:To evaluate the cumulative incidence of end-stage renal disease(ESRD)in Chinese hypertensive type2diabetic patients with microalbuminuria(DHM)treated with different regimes,and to provide reference for decision makers.METHODS:A peer-reviewed Markov model that simulated progression from microalbuminuria to nephropathy,dou?bling of serum creatinine,ESRD,and all-cause mortality in patients with DHM was adapted to China.Three strategies were compared:(1)early use of irbesartan(i.e.prompt treatment in subjects with microalbuminuria);(2)late use of irebesartan(i.e.as from overt nephropathy);(3)standard hypertension care(with comparable blood pressure control).Cumulative incidence of ESRD,costs and life expectancy were projected for a hypothetical cohort of1000subjects.Treatment-specific progression and mortality probabilities were derived from published trials:IRMA-2(in microalbuminuria)and IDNT(in overt nephropathy).Medical management and cost data per state were obtained from published local sources.A flexible time horizon up to25years and third party payer perspective were used.Future costs and LE were discounted at3%yearly.RESULTS:When compared with standard blood pressure control,early use of irbesartan was evaluated to reduce the cumulative incidence of ESRD from(mean?standard deviation)8%to22%,save RMB30348(US$3667),and add0.638life years per treated patient.Late use of irbesartan was dominant over control group but dominated by early irbesartan.Break-even occurred after13years.CON?CLUSION:Treating DHM patients by early use of irbesartan is evaluated to reduce the incidence of ESRD,extend life and reduce costs.Treating patients at a later stage is still beneficial,however to a lower extent.
10.Effects of POH in combination with STI571 on the proliferation and apoptosis of K562 cells.
Journal of Huazhong University of Science and Technology (Medical Sciences) 2004;24(1):41-4
The effects of monoterpene perilly alcohol (POH) alone or in combination with STI571 on the proliferation and apoptosis of the cell line K562 positive for Bcr/Abl were investigated. By using cell culture, the effect of the drugs on the proliferation of the cells was studied. TUNEL and flow cytometry assay of FITC-Annexin V and PI labeled cells were applied to detect the effects of the drugs on the apoptosis of the cells. The results showed that at 36 h, IC50 of POH on K562 positive for Bcr/Abl and HL-60 negative for Bcr/Abl were 81.0 +/- 11.3 micromol/L and 113.6 +/- 23.4 micromol/L respectively (P>0.05). POH could inhibit the proliferation of K562 in a time- and dose-dependent manner with the inhibitory rate of 100 micromol/L POH on K562 cells at 36 h being (53.2 +/- 3.65)%. K562 cells were more sensitive to STI571 than POH. IC50 of STI571 on K562 cells in 36 h was (0.256 +/- 0.054) micromol/L. In a time- and dose-dependent manner, POH induced the apoptosis of K562 cells with the percentage of apoptotic cells by 100 micromol/L POH at 40 h being (21.0 +/- 3.3)%. Both 100 micromo/L POH and 0.2 micromol/L STI571 had the same inhibitory effects on the K562 cells at 36 h. But at 12 and 24 h, the inhibitory rate of POH was significantly higher than that of STI571 (P<0.05) and the ability of STI571 inducing apoptosis at 36 h was greater than that of POH. 50 micromol/L, 100 micromol/L and 200 micromol/L POH in combination with 0.2 micromol/L STI571 could obviously increase the inhibitory effects on the cellular proliferation. Combined use of 50 micromol/L, 100 micromol/L, 200 micromol/L with 0.2 micromol/L STI571 could strongly induced apoptosis, especially 200 micromol/L POH in combination with 0.2 micromol/L STI571. It was concluded that the antileukemia effect of POH had no obvious Bcr/Abl positive selectivity. POH can inhibit the proliferation of K562 and induce the apoptosis in a time- and dose-dependent manner. K562 cells were more sensitive to STI571 than POH. POH in combination with STI571 could obviously enhance the abilities of STI571 inhibiting the proliferation and inducing apoptosis of K562 cells.
