1.Transcranial Doppler monitoring during carotid endarterectomy
International Journal of Cerebrovascular Diseases 2009;17(8):587-590
Carotid endarterectomy (CEA) can effectively treat symptomatic carotid stenosis, however, perioperative stroke is the most important complication of CEA. The microemboli generated before and after the operation are the most important reason for causing perioperative stroke. In addition, the hypoperfusion and postoperative hyperperfusion syndrome caused by intraoperative clipping of carotid artery, as well as carotid restenosis or occlusion after CEA are all the causes of perioperative stroke. As a non-invasive, real-time monitoring tool, transcranial Doppler (TCD) can be widely used in intraoperative monitoring of CEA, It is able to detect a variety of perioperative blood flow changes and the production of microemboli, and thus effectively predicts the occurrence of perioperative stroke, and decreases the risks of perioperative stroke.
2.Pathophysiologic mechanisms and therapeutic methods of sarcopenia in cancer cachexia
Chinese Journal of Clinical Nutrition 2016;24(3):179-185
Sarcopenia is a major clinical characteristic of cancer cachexia .The main pathophysiologic mechanism of sarcopenia related to cancer cachexia is abnormality between anabolic and catabolic pathways of muscle mediated by chronic inflammation .The major treatments for sarcopenia in cancer cachexia currently in-clude hormone therapy , nutrition support , exercise therapy , and other medications , which could not effectively prevent muscle loss or enhance muscle function .Better understanding of the pathogenetic processes of cancer cachexia-related sarcopenia may help in finding targets for an effective therapy .

Objective To evaluate the actual mismatch risk for KIR genes,KIR ligand HLA-C gene and KIR ligand HLA-Bw4I80 related genes in kidney transplant recipients and their donors.Method KIR genes,KIR ligand HLA-C gene and KIR ligand HLA-Bw4I80 related genes were analyzed in 322 recipients and their donors who received kidney transplantation.The effect of mismatches on acute rejection after transplantation was studied as well.Result In 322 cases of recipients and their donors,average mismatch risk for KIR-L gene was 4.73%,9.10% for KIR-S gene and 1.95% for KIR ligand HLA-C gene respectively.There were 245 cases (76.09%) of KIR ligand HLA-Bw4I80 related genes mismatch and 77 cases (23.91 %) of match resepctively.There was no statistically significant difference in AR rate between KIR ligand HLA-Bw4I80 related genes mismatch group and match group (8.16% in 245 vs.7.79% in 77) (P>0.05).AR reversal rate in mismatch group and match group was 95.0% and 66.7% (P>0.05).Conclusion The mismatch risk for KIR ligand HLA-Bw4I80 related genes was even common between kidney transplant recipients and their donors,and this specific mismatch may be of benefit to patients who undergo actuate rejection.Further study is still required.

Objective To study the surgical treatment of the primary retroperitioneal sarcoma(RPS). Methods The treatment and prognosis of 63 patients with primary retroperitoneal sarcomas (liposarcomas and leiomyosarcomas) from Jan 1992 to Dec 2000 were analyzed retrospectively. Results The rate of complete tumor resection was 88.2%, and concomitant resection of involved adjacent organs was 21.6%. There was no operation death. The median survival time(MST) in liposarcomas that for was 36.5months, and leiomyosarcomas was 27.6 months. The MST in highly differentiated tumor was 34.7 months,and that of intermiade and low differtiated tumors was 18.1months(P

Nine known compounds were isolated from the chlorofrom soluble fraction of ethanolic extract of Belamcanda chinensis(L. )DC.. Their structures were identified as irigenin(Ⅰ),dichotomitin(Ⅱ),irisflorentin (Ⅱ),3-stigmastenol (Ⅳ), apocynin (Ⅴ), tectoridenin (Ⅵ), ?-sitosterol (Ⅶ), 3', 4', 5, 7-tetrahydroxy-8-methoxyisoflavone (Ⅶ)and polyoctapenten (Ⅹ) by spectorscopic methods (UV, IR, EIMS, 1HNMR, 13CNMR). Compounds Ⅱ, Ⅳ, Ⅹ and Ⅻ were obtained for the first time from the plant.

Objective To compare the protective effect of colloidal bismuth subcitrate-1 (CBS-1, Lizudele), or colloidal bismuth subcitrate-2 (CBS-2, De-Nol) and sucralfate against gastric mucosal lesion and to investigate their mechanisms. Methods Gastric mucosal injury of rats was induced by ethanol, stress, aspirin and hydrochloric acid. Gastric ulcer was then induced by 50% acetic acid applied to the gastric tunica serosa. We observed the protective effects against gastric mucosal lesion and measured the injury index and the area of ulcer in each group. Statistical t test was used to compare the difference of each group. Results (1)CBS-1, CBS-2, and sucralfate had protective effect against lesions caused by ethanol, stress, aspirin and hydrochloric acid and could promote acetic acid-induced gastric ulcer healing. (2) The mechanisms of protective effect and ulcer healing promotion were that these drugs could increase gastric blood flow and increase activities of QR, GST and GR, and could also promote overexpression of bFGF mRNA and iNOS mRNA. Conclusion Gastric mucosal protective drugs, CBS and sucralfate had effect of resisting injury and promoting ulcer healing. The mechanisms were that they could increase gastric mucosal blood flow and the expression of bFGF mRNA and iNOS mRNA, and reduce oxygen free radical.

Objective To compare therapeutic effect of Losartan and hydrochlorothiazed compound prepara- tion and Losartan in patients with mild to moderate hypertension and to conduct economical evaluation. Methods The trial began with 2 weeks lead-in period and followed by 8 weeks therapy. 99 cases of mild to moderate hyperten- sion were randomly divided into two groups: compound preparation group ( n = 50) and Losartan (n = 49). The pa- tients were given Losartan 50 mg/h ydrochlorothiazed 12.5 mg compound preparation and Losartan 50 mg ,once a day. If the SeDBP≥85 mm Hg at 4th week, Losartan was added to 50 rag. Results After two, four and eight weeks treatment, systolic blood pressure and diastolic decreased obviously (P < 0.01 for each) ;The overall effective rate of of antihypertension was the same in both groups, but the different ratio of availability and validity in two groups was significant ( P < 0.05 for each). Conclusion Losartan/hydrochlorothiazed compound preparation has significant advantage in improving both systolic and diastolic pressure compared with monotherapy of Losartan. In ad- dition, the patients receiving compound preparation are well tolerated, with higher compliance.
