OBJECTIVETo investigate the changes of serum levels of chitinase-3-like-1 protein (YKL-40) and high-sensitivity C-reactive protein (hs-CRP) in patients with non-ST segment elevation acute coronary syndrome (ACS), to explore its correlation with its severity, and to observe the effects of Guizhi Fuling Decoction (GFD) on levels of blood lipids, YKL-40, and hs-CRP.

METHODSRecruited were 72 patients with unstable angina (UA) or non-ST segment elevation myocardial infarction (NSTEMI) at Department of Integrative Medicine, First Affiliated Hospital of Xinxiang Medical College from August 2010 to June 2011. They were randomly assigned to the treatment group (36 cases) and the control group (36 cases). All patients were treated by routine treatment, but patients in the treatment group took GFD additionally. The course of treatment was four weeks. According to the severity degree, all patients were graded to four ranks: low-risk group of UA, medium-risk group of UA, high-risk group of UA, and NSTEMI. The levels of YKL-40 and hs-CRP, and the correlation of severity degree were analyzed. Before and after treatment levels of triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) were measured. Before treatment, at two weeks, and after treatment the serum levels of YKL-40 and hs-CRP were detected. The relationship of YKL-40, hs-CRP and the severity of the disease were analyzed.

RESULTSLevels of YKL-40 and hs-CRP were positively correlated with the severity of the disease respectively (r = 0.729, P < 0.05; r = 0.655, P < 0.05). The positive correlation also existed between YKL-40 and hs-CRP (r = 0.848, P < 0.05). There was no statistical difference in the levels of blood lipids, YKL-40, or hs-CRP between the two groups before treatment (P > 0.05). Compared with before treatment, the levels of YKL-40 and hs-CRP significantly decreased in both groups after two weeks of treatment (P < 0.05). The levels of TG, TC, LDL-C, YKL-40, and hs-CRP significantly decreased, while the HDL-C level increased in both groups after treatment (P < 0.05). The level of HDL-C in the treatment group was higher, while levels of YKL-40 and hs-CRP were lower after treatment, when compared with the control group (all P < 0.05).

CONCLUSIONOn the basis of anti-inflammation and adjusting blood lipids by Western medicine, GFD could further reduce the serum levels of YKL-40 and hs-CRP of ACS patients, elevate the HDL-C level, and play anti-atherosclerosis effects.

In order to study the protective effects of Schizonepeta volatile oil (Sto）on endotoxin poisoning mice, and the relatively content of each chemical osubstance in Schizonepeta volatile oil was measured using GC-MS. The mare C57BL/6J mice were randomly divided into five groups including the normal group, model group, dexamethasone group (5 mg•kg⁻¹), and Sto (0.226 and 0.452 g•kg⁻¹, respectively) groups. The dexamethasone group was given the drugs once time by intraperitoneal injection on the 5th day, while the other mice were given drugs by oral administration once a day for 5 days. Then, the normal group was injected with the saline and the other groups were injected LPS (15 mg•kg-1) after 30 minutes of the last administration. After LPS injection twelve hours, the blood, serum, and lung tissue of mice were collected. The IL-18, IL-1β, IL-5, TNF-α, MCP-1, MIP-1β, M-CSF, and GM-CSF were measured in serum by ELISA and Luminex Magpix. The white cell (WBC) and platelet (PLT) in blood were counted and lung, spleen, and thymus index were calculated. The lung histopathology was performed at the same time. The GC-MS results showed that the relative content of menthone and pulegone are 46.67% and 33.92%, respectively. The Sto (0.452 and 0.226 g•kg⁻¹, respectively) reduced the levels of IL-1β, IL-5, TNF-α, MCP-1, MIP-1β, and M-CSF in serum (P<0.01 or P<0.05). The 0.452 g•kg⁻¹ Sto also reduced the levels of IL-18 and GM-CSF in the serum (P<0.01 or P<0.05). And the 0.226 g•kg⁻¹ Sto showed good anti-inflammatory effects by reducing neutrophil infiltration in the lung tissue. But the Sto had no effect on the increasing of WBC, spleen and lung index as well as decreasing of PLT and thymus index. The results showed that Sto has a protective effect in LPS-induced exdotoxin poisoning mice, its mechanism is related to inhibit the release of varies of inflammatory cytokines and reduce the inflammation reaction.

Objective: To investigate the safety and effectiveness of radical retropubic prostatectomy (RRP) with adjuvant androgen deprivation or external radiotherapy in the treatment of prostate cancer (PCa) with pelvic lymph node metastasis (PLNM). METHODS: Twenty PCa patients underwent bilateral pedal lymphangiography (PLG) preoperatively, and 11 of them received lymph node aspiration for examination of the mRNA expressions of prostate-specific antigen (PSA) and prostate-specific membrane antigen (PSMA) in the lymph fluid by real-time RT-PCR. All the patients were treated by RRP with extended dissection of pelvic lymph nodes, and 3 of them by external radiotherapy in addition after recovery from urinary incontinence because of positive surgical margins, followed by adjuvant androgen deprivation therapy. RESULTS: Real-time RT-PCR showed positive mRNA expressions of PSA and PSMA in the lymph fluid of the 11 patients, all pathologically confirmed with PLNM. The median intraoperative blood loss was 575 ml, with blood transfusion for 5 cases. Positive surgical margin was found in 3 cases, lymphorrhagia in 2 and urinary leakage in another 2 each. There were no such severe complications as vascular injury and rectum perforation. The patients were followed up for 6－48 (mean 42) months, during which, biochemical recurrence was observed in 12 cases at a median of 12 months postoperatively and 2 patients died at 12 and 48 months respectively. CONCLUSIONS Bilateral PLG and lymph node aspiration for examination of the mRNA expressions of PSA and PSMA in the lymph fluid help to confirm PLNM preoperatively. Radical retropubic prostatectomy with adjuvant androgen deprivation or external radiotherapy is safe and effective for the treatment of PCa with PLNM, but it should be chosen cautiously for those with Gleason 5+5.
