ABSTRACT
OBJECTIVE@#To compare the clinical therapeutic effect between electroacupuncture at "four points of sacral region" and transurethral Erbium laser in treatment of moderate to severe stress urinary incontinence after radical prostatectomy.@*METHODS@#A total of 68 patients of moderate to severe stress urinary incontinence after radical prostatectomy were divided into an electroacupuncture group (34 cases) and an Erbium laser group (34 cases, 3 cases dropped off) according to the settings. In the electroacupuncture group, electroacupuncture was applied at "four points of sacral region", i.e. points of 0.5 cun beside bilateral sacrococcygeal joints and bilateral Huiyang (BL 35), with continuous wave, 2 Hz in frequency, 60 min each time, once every other day, 3 times a week, 12 times as one course of treatment. In the Erbium laser group, transurethral Erbium laser technology was given, once every 4 weeks as one course of treatment. Both groups were treated for 5 courses. The scores of the International Consultation on Incontinence questionnaire-short form (ICI-Q-SF) and the incontinence quality of life questionnaire (I-QOL) were observed before treatment, after each course of treatment and in follow-up after 1 and 2 months of treatment completion, respectively, and the clinical efficacy was evaluated after treatment in the two groups.@*RESULTS@#Compared with those before treatment, the ICI-Q-SF scores were decreased while the I-QOL scores were increased after 5 courses of treatment and in follow-up after 1, 2 months of treatment completion in the two groups (P<0.01). The ICI-Q-SF score in follow-up after 2 months of treatment completion were higher than that after 5 courses of treatment in the Erbium laser group (P<0.05). After 3, 4, 5 courses of treatment and in follow-up after 1 and 2 months of treatment completion, the ICI-Q-SF scores in the electroacupuncture group were lower than those in the Erbium laser group (P<0.05, P<0.01); after 2, 3, 4, 5 courses of treatment and in follow-up after 1 and 2 months of treatment completion, the I-QOL scores in the electroacupuncture group were higher than those in the Erbium laser group (P<0.01). The change ranges of ICI-Q-SF score and I-QOL score between before treatment and after each course of treatment in the electroacupuncture group were lager than those in the Erbium laser group (P<0.01, P<0.05). The total effective rate was 61.8% (21/34) in the electroacupuncture group, which was superior to 19.4 (6/31) in the Erbium laser group (P<0.01).@*CONCLUSION@#Both electroacupuncture at "four points of sacral region" and transurethral Erbium laser can improve the clinical symptoms and the quality of life in patients of moderate to severe stress urinary incontinence after radical prostatectomy. The short-term efficacy and long-term efficacy of electroacupuncture are superior to the Erbium laser technology.

ABSTRACT
Cancer-related fatigue (CRF) is a common and one of the most severe symptom in the period of onset, diagnosis, treatment and rehabilitation process of cancer. But there are no confirmed measures to relieve this problem at present. Traditional Chinese medical comprehensive therapy has its advantages in dealing with this condition. Based on the research status of CRF, the following problems have been analyzed and solved: the term of CRF has been defined and recommended, and the definition has been made clear; the disease mechanism is proposed, i.e. healthy qi has been impaired in the long-term disease duration, in the process of surgery, chemotherapy, radiotherapy and biology disturbing; it is clear that the clinical manifestations are related to six Chinese medicine patterns: decreased functioning of the Pi (Spleen) and Wei (Stomach), deficiency of the Pi with dampness retention, deficiency of the Xin (Heart) and Pi, disharmony between the Gan (Liver) and Pi, deficiency of the Pi and Shen (Kidney), and deficiency of the Fei (Lung) and Shen. Based on its severity, the mild patients are advised to have non-drug psychological intervention and sleep treatment in cooperation with appropriate exercise; diet therapy are recommended to moderate patients together with sleep treatment and acupuncture, severe patients are recommended to have herbal treatment based on pattern differentiation together with physiological sleep therapy.

The feasibility of simultaneously loading both liposoluble and water-soluble components of Salvia miltiorrhiza in emulsion was discussed, in order to provide new ideas in comprehensive application of effective components in S. miltiorrhiza in terms of technology of pharmaceutics. With tanshinone II (A) and salvianolic acid B as raw materials, soybean phospholipid and poloxamer 188 as emulsifiers, and glycerin as isoosmotic regulator, the central composite design-response surface method was employed to optimize the prescription. The coarse emulsion was prepared with the high-speed shearing method and then homogenized in the high pressure homogenizer. The biphasic drug-loading intravenous emulsion was prepared to investigate its pharmaceutical properties and stability. The prepared emulsion is orange-yellow, with the average diameter of 241 nm and Zeta potential of -35.3 mV. Specifically, the drug loading capacity of tanshinone II (A) and salvianolic acid B were 0.5 g x L(-1) and 1 g x L(-1), respectively, with a good stability among long-term retention samples. According to the results, the prepared emulsion could load liposoluble tanshinone II (A) and water-soluble salvianolic acid B simultaneously, which lays a pharmaceutical foundation for giving full play to the efficacy of S. miltiorrhiza.

This study was aimed to investigate the expression of biomarkers (PTEN, mTOR, NF-kB, CD44, PI3K) related with bone marrow cells in patients with acute myelogenous leukemia. The immunohistochemical method was used to detect the expression of PTEN, mTOR, NF-kB, CD44, PI3K in 20 patients. The AML patients were divided into remission group and non-remission group after calculating the percentage of leukemia cells in bone marrow. The results showed that by optical microscopy, the positive expression rates of PTEN, mTOR, NF-kB, CD44 and PI3K in remission group were 33.3%, 33.3%, 77.8%, 22.2%, 0, respectively; meanwhile, in non-remission group, the positive expression rates of above-menthioned biomarkers were 63.6%, 18.2, 90.9, 63.6%, 0, respectively. The percentage and mean OD for PTEN and CD44 were statistically different between the two groups (P < 0.05), but for mTOR, NF-kB and PI3K were not statistically differenly (P > 0.05). It is concluded that the high expression of PTEN and CD44 can be regarded as an important index for diagnosis and prognosis in acute myelogenous leukemia.

<p><b>OBJECTIVE</b>To evaluate the current cornea donation awareness of tissue donors in the city of Nanjing, China.</p><p><b>METHODS</b>Altogether 2000 registered tissue donors in the Red Cross Eye Bank of Nanjing by the end of 2010 and 2000 control residents of Nanjing in February to June 2011 were randomly selected to participate in our field questionnaire survey. The questionnaire consisted of questions regarding the understanding of cornea donation, the attitude toward cornea donation, and attitude toward legislation and free donation. The awareness of cornea donation between the registered tissue donors and residents was compared. Related factors of the willing-ness to donate corneas and to become a tissue donor were evaluated with univariate and multiple logistic regression analysis.</p><p><b>RESULTS</b>A total of 1867 (response rate: 93.4%) tissue donors and 1796 (response rate: 89.8%; effective questionnaires: 1697) residents participated in this survey. For the questions about the knowledge of cornea donation, 90.3% tissue donors (residents: 78.9%) knew that donated corneas could be used for transplantations; 71.2% tissue donors (residents: 47.6%) knew that the appearance would not be destroyed after cornea donation; 70.7% tissue donors (residents: 20.0%) knew the formalities to become a cornea donor. For attitude toward cornea donation, 82.2% tissue donors (residents: 45.1%) were willing to donate corneas or eyeballs after death; 84.0% tissue donors (residents: 30.2%) had discussed with their families about donation; 85.1% tissue donors (residents: 24.8%) supported their families' or friends' cornea donation. For attitude toward legislation and free donation, 88.3% tissue donors (residents: 61.3%) approved of legislation to regular cornea donation; 72.2% tissue donors (residents: 38.8%) thought that cornea or organ donation should be gratis. The difference between two groups was significant (P<0.001). However, some tissue donors did not know cornea donation well, some even opposed the legislation of cornea donation and free donation protocol. For the factors influencing the willingness to donate corneas, population was the most relevant factor (P<0.001), since tissue donors were more willing to donate corneas than residents. Other significantly related factor were age, gender, occupation, and education level (P<0.001), while political status or religion were not significant. For the factors related to becoming a tissue donor, older age, male, white-collars (including white-collar, civil servant, teacher, soldier, lawyer, salesman, healthcare provider), higher education level, party members (including the Chinese Communist Party members, democratic party members, and the Communist Youth League members) (P<0.05).</p><p><b>CONCLUSIONS</b>The registered tissue donors have better understanding and more positive attitude towards cornea donation than control residents do. They approve of the legislation of cornea donation and free donation protocol. It may be more effective to target the population of over 58 years old, male, white-collars, well-educated people, and party members in the promotion of cornea donation.</p>

The study was purposed to investigate the growth inhibitory effect of tanshinones on K562 cell line and the relationship between their structures and cytotoxicity. The modified MTT assay was adopted to measure the inhibitory effect of tanshinones at different concentrations and chemical structures on K562 cells, and the changes of cell morphology were observed by inverted phase contrast microscopy. The results indicated that the tanshinones could inhibit the proliferation of K562 cells effectively, and their cytotoxicities on K562 cells showed concentration- and time-dependent manners. The IC(50) of dihydrotanshinone I, tanshinone I, tanshinone IIA and cryptotanshinone at 24 hours were 0.91, 4.04, 5.95, 13.85 µg/ml at 48 hours were 0.37, 1.35, 1.71, 6.71 µg/ml; at 72 hours were 0.33, 0.46, 0.82, 6.02 µg/ml, respectively. It is concluded that all of the four tanshinones have proliferation inhibitory effect on K562 cell line, among them the dihydrotanshinone I is the most active one, followed by tanshinone I, tanshinone IIA and cryptotanshinone subsequently, indicating that the chemical structure of aromatic ring A of tanshinones can enhance their cytotoxicity and the structure of furan ring C may influence the cytotoxicity, but their mechanism is still remained to be further investigated.
