This study was aimed to investigate the effect of homoharringtonine (HHT) on K562 cell proliferation, apoptosis and expression of BCL-2 and NF-κB proteins. The cells proliferation was assayed with MTT method, the cell apoptosis, cell cycle and BCL-2 expression were analyzed with flow cytometry, NF-κB protein expression was detected with Western blot. The results showed that HHT concentration-dependently inhibited proliferation of K562 cells, the IC50 at 48 h was 43.89 ng/ml. Treated with HHT 10 ng/ml for 48 h, K562 cell apoptosis significantly increased, cell cycle was blocked at G0/G1, the expression level of BCL-2 and NF-κB proteins was lower than that in control group (P < 0.05). It is concluded that HHT may inhibit the proliferation of K562 cells, and down-regulating expression levels of BCL-2 and NF-κB may be one of its anti-CML mechanisms.

OBJECTIVETo access the prevalence of menopause-like symptoms, and their related factors in old and middle-aged males in the area of Hefei.

METHODSThis study included 1 026 males aged over 45 years that came to the clinic for health examination. We collected their personal data, and evaluated their general health status and the results of the questionnaire investigation using the Aging Males' Symptoms (AMS) scale.

RESULTSThe total incidence of menopause-like symptoms was 64.7% among the old and middle-aged males in Hefei area, of which 58.1% were mild, 30.9% moderate and 11.0% severe. The average AMS score was 31.2 +/- 6.8, in which the scores on psychological, physical and sexual function symptoms were 8.3 +/- 2.1, 12.4 +/- 4.8 and 9.3 +/- 4.5, respectively. Sexual function symptoms were increased significantly with the increase of age (P < 0.05), but psychological and physical symptoms showed no obvious correlation with age (P > 0.05). The main risk factors of menopause-like symptoms included age, smoking, diabetes, cardiovascular diseases, and obesity, but physical exercise was an important protective factor against them.

CONCLUSIONWith the increase of age, the prevalence of male menopause-like symptoms rises and sexual function declines gradually, but psychological and physical scores are not affected significantly. Age, general health status and lifestyle are closely associated with the prevalence of menopause-like symptoms among old and middle-aged males.

OBJECTIVETo explore the relation between erythrocyte sedimentation rate(ESR) and postoperative recurrence of spinal tuberculosis.

METHODSEighty cases (36 males and 44 female,ranging from 20 to 71 years with an average of 38.2 years)of spinal tuberculosis treated with focus debridement were divided into two groups according to the preoperative value of ESR: Group A (ESR > or = 40 mm/h) and Group B (ESR < 40 mm/h). Patients in two groups were treated by the same method. The postoperative recurrences in two groups were analyzed.

RESULTSAll the patients were followed up. The recurred cases were 5 in Group A and 4 in Group B. There is no significant difference between two groups.

CONCLUSIONESR is not the key factor to choose the right operative time to perform debridement.

Purpose To investigate the value of application of D2-40/CD34-CK cocktail antibodies by double immunohistochemical staining for assessment of lymphovascular invasion (LVI) and to determine its prognostic significance in colorectal cancer with insufficient lymph node harvest. Methods Specimens from 133 cases of colorectal cancer with less than 12 lymph nodes were selected. HE staining and double immunohistochemical staining of the cocktail antibodies were performed to compare the difference of the two methods in screening for LVI. The The relationship between LVI confirmed by cocktail antibody immunohistochemical staining and clinicopathological characteristics and overall survival (OS) of patients was analyzed. Results (1) The detection rates of cocktail antibody double immunohistochemical staining and HE staining for LVI were 42.9％ (57/133) and 21.8％ (29/133) with statistically significant difference (P < 0.001). (2) The presence of LVI confirmed by double staining was significantly associated with Dukes staging, depth of invasion, clinical stages, lymph node metastasis and tumor budding (P < 0.05). (3) The presence of LVI, the location and extent of LVI, and the number of tumor cells in thrombus ≥5.5 for cases with LVI ≤2 clusters, were significantly associated with OS (P < 0.05). Conclusion D2-40/CD34-CK cocktail antibodies double staining is superior to routine HE staining in assessing LVI. LVI is intimately associated with tumor stage, lymph nodes metastasis and tumor budding, and it is an independent prognostic factor for CRC patients. It should be a supplementary examination for these patients with insufficient lymph node harvest.
