A new composite organic oscillating reaction system based on BrO₃-Ce(SO₄)₂-H₂SO₄-malonic acid/tartaric acid was proposed in this paper. On the basis of the influence of the concentration of each component on the stability and characteristic parameters of the blank system, the electrochemical fingerprints of 30 kinds of traditional Chinese medicines (TCM) were obtained. The results showed that the electrochemical fingerprint can be used for the identification of TCMs, the distinguishment of different parts and the appraisal of genuineness, which is fast, sensitive and accurate. At the same time, we explored and verified the mechanism of oscillation and the formation mechanism of TCM fingerprint.

OBJECTIVETo investigate how network education can improve college students' knowledge on sexual and reproductive health in Ningbo city.

METHODSFrom December 2012 to June 2013, we conducted a questionnaire investigation among college students in Ningbo city about the effects of network education on their knowledge about sexual psychology, sexual physiology, sexual ethics, and reproductive health.

RESULTSA total of 7 362 college students accomplished the investigation, of whom 2 483 (42.1% males and 57.9% females) received network education, while the other 4 879 (24.1% males and 75.9% females) did not. Approximately 47.1% of the male and 28.0% of the female students acquired sexual and reproductive knowledge via network education. Reproductive health-related network education significantly enriched the students' knowledge about the reproductive system and sex, pubertal development, sexual physiology, conception and embryonic development, methods of contraception, sexual psychology, sexually transmitted diseases and their prevention, pregnancy care and eugenics, and environment- and occupation-related reproductive health (P < 0.01). It also remarkably improved their cognitive attitude towards reproductive health knowledge (P < 0.01). Those who received reproductive health-related network education showed a significantly higher rate of masturbation (P < 0.01) but markedly later time of the first masturbation (P < 0.01) than those who did not.

CONCLUSIONNetwork education can enhance the effect of reproductive health education among college students and improve their sexual experience and health.

Objective To retrospectively analyze the effect of comprehensive and whole process blood man-agement on allogeneic transfusion in patients undergoing orthopedic surgery.Methods A total of 7082 patients (3320 in 2013, 3762 in 2014) who underwent orthopedic surgery in the period from January 2013 to December 2014 in Department of Orthopedics, Peking Union Medical College Hospital were retrospectively analyzed, among which 2178 cases in 2013 and 2322 cases in 2014 were considered at high hemorrhage risk.Since January 2014, the Department has implemented individualized comprehensive blood management measures covering the whole perioper-ative period, involving perioperative autologous blood transfusion technology, treatment improvement during surgery and perioperative period, drug intervention, and strict following of blood transfusion principles.We compared the overall conditions of allogeneic blood transfusion in 2014 with those in 2013, assessing the impact of those new man-agement measures on allogeneic blood transfusion in patients who underwent orthopaedic surgery.Results The differences in gender, age, types and distribution of high hemorrhage risk surgeries were not statistically significant between the two years.However, both the overall number of orthopedic surgeries and the number of surgeries with high hemorrhage risk were larger in 2014 than in 2013.The total volume of allogeneic blood transfusion in 2014 was 106 950 ml (713 cases), lower than the volume in 2013 (121 600 ml, 760 cases).Similarly, the total amount of transfused concentrated red blood cells in 2014 (2543 U) was less than that in 2013 (2804 U) .The expense on al-logeneic transfusion was 680 720 RMB in 2014, accounting for 0.97%of the total medical expenses (70 287 242.03 RMB) of the patients receiving allogeneic blood transfusion and 0.35%of the overall medical expenses (196 100 485 RMB) , which were all lower than the corresponding figures in 2013 (1.04%and 0.42%, respectively) .More-over, the average length of hospital stay in 2014 was lower than that in 2013 (12.46 d vs.12.90 d) , as well as the incidence rate of complications (2.02%vs.5.03%).Conclusion In addition to ensuring safe healthcare and efficient medical service, comprehensive and whole process blood management could reduce the volume of al-logeneic blood transfusion in patients undergoing orthopedic surgeries.

OBJECTIVETo investigate the relationship of the histopathologic grade and extent of prostatic inflammation with the level of serum PSA in patients with type IV prostatitis.

METHODSWe performed transrectal ultrasound-guided prostate biopsy for 120 patients suspected of prostate cancer and included in this study only those with benign prostate hyperplasia (BPH) and prostatitis (n = 46), excluding the cases with prostate cancer and those with BPH but no prostatitis. We evaluated the relationship between prostatic inflammation and serum PSA levels based on the three-grade pathohistologic criteria for the extent, location and aggressiveness of prostatic inflammation. The serum tPSA levels, fPSA levels, % fPSA, and PSAD were compared among different groups.

RESULTSAs for the extent of inflammation, 35 of the 46 included cases were grade I (tPSA: [8.46 +/- 4.09] microg/L; fPSA: [1.75 +/- 0.93] microg/L; PSAD: 0.15 +/- 0.11), 7 were grade II (tPSA: [15.26 +/- 5.26] microg/L; fPSA: [2.54 +/- 0.72] microg/L; PSAD: 0.26 +/- 0.07) and 4 were grade III (tPSA: [21.05 +/- 7.58] microg/L; fPSA: [3. 19 +/- 1.13] microg/L; PSAD: 0.42 +/- 0.19), with statistically significant differences among the three groups in the levels of tPSA (P = 0.001), fPSA (P = 0.008) and PSAD (P < 0.001). Regarding the location of inflammation, 19 cases were grade I, 17 were grade II and 10 were grade II, with no significant differences in tPSA, fPSA and %fPSA among the three grades (P > 0.05). As for the aggressiveness of inflammation, 32 cases were grade I (tPSA: [8.37 +/- 4.07] microg/L; fPSA: [1.76 +/- 0.93] microg/L; PSAD: 0.14 +/- 0.11), 10 were grade II (tPSA: [13.30 +/- 5.69] microg/L; fPSA: [3.27 +/- 2.21] microg/L ; PSAD: 0.25 +/- 0.06) and 4 were grade III (tPSA: [21.05 +/- 7.58] microg/L; fPSA: [3.19 +/- 1.13] microg/L; PSAD: 0.42 +/- 0.19), with statistically significant differences among the three grades in the levels of tPSA (P = 0.002), fPSA (P = 0.024) and PSAD (P < 0.001). The extent of inflammation was positively correlated with the levels of tPSA (r = 0.6, P < 0.001), fPSA (r = 0.5, P = 0.001) and PSAD (r = 0.6, P < 0.001), and so was the aggressiveness of inflammation (tPSA: r = 0.5, P < 0.001; fPSA: r = 0.4, P = 0.008; PSAD: r = 0.7, P < 0.001), but a negative correlation was found between the aggressiveness of inflammation and %fPSA (r = -0.4, P = 0.013).

CONCLUSIONThe aggressiveness and extent of prostatic inflammation in asymptomatic prostatitis patients are significantly correlated with the level of serum PSA, which may help pathologists to avoid unnecessary repeated biopsies for patients with high-grade prostatitis.

BACKGROUNDChromosomal abnormalities have been shown to play an important prognostic role in multiple myeloma (MM). Interphase fluorescence in situ hybridization (i-FISH) has been much more effective to identify cytogenetic aberrations in MM than conventional cytogenetic technique (CC). To clearly determine the cytogenetic features of Chinese MM patients and identify their prognostic implications, we designed a multicenter study based on i-FISH including 672 patients from 52 hospitals in China.

METHODSAll 672 patients were systematically screened for the following genomic aberrations: del(13q), IgH rearrangement, del(p53) and 1q21 amplifications.

RESULTSThe analysis showed that the chromosomal changes were detected in 22.1% patients by CC and in 82.3% patients by i-FISH. The most common abnormalities by CC were chromosome 1 aberrations (48.4%), -13/13q- (37.6%), hyperdiploidy (36.6%), hypodiploidy (30.1%) and IgH rearrangements (23.7%). The most frequent abnormalities by FISH was del(13q), which was found in 60.4% patients, whereas IgH rearrangement, 1q21 amplification and p53 deletions were detected in 57.6%, 49.0% and 34.7% cases, respectively. By statistical analysis, -13/13q- by CC was associated with low level of platelet (P = 0.015), hyperdiploidy was associated with low level of serum albumin (P = 0.028), and IgH rearrangement by FISH was associated with high level of β2 microglobulin (P = 0.019). Moreover, 1q21 amplification and del(p53) by FISH conferred a high incidence of progressive disease (PD) after initial therapy. Metaphase detection of IgH rearrangements and chromosome 1 aberrations concurrently was associated with a short progression free survival (PFS) (P = 0.036). No significant prognostic implications of other cytogenetic abnormalities were found associated with overall survival and PFS.

CONCLUSIONSChinese MM patients had similar cytogenetic abnormalities compared with the previous reported studies. However, the prognostic significance of FISH aberrations were not clearly determined and further study is required.

OBJECTIVETo explore the most effective herbal combinations commonly used by highly experienced Chinese medicine (CM) physicians for the treatment of insomnia.

METHODSWe collected and analyzed data related to insomnia treatment from the clinics of 7 highly experienced CM physicians in Beijing. The sample included 162 patients and 460 consultations in total. Patient outcomes, such as sleep quality and sleep time per day, were manually collected from the medical records by trained CM clinicians. Three data mining methods, support vector machine (SVM), logistic regression and decision tree, and multifactor dimensionality reduction (MDR), were used to determine and confirm the herbal combinations that resulted in positive outcomes in patients suffering from insomnia.

RESULTSResults show that MDR is the most efficient method to predict the effective herbal combinations. Using the MDR model, we identified several combinations of herbs with 100% positive outcomes, such as stir-fried spine date seed, Szechwan lovage rhizome, and prepared thinleaf milkwort root; white peony root, golden thread, and stir-fried spine date seed; and Asiatic cornelian cherry fruit with fresh rehmannia.

CONCLUSIONSResults indicate that herbal combinations are effective treatments for patients with insomnia compared with individual herbs. It is also shown that MDR is a potent data mining method to identify the herbal combination with high rates of positive outcome.
