Data mining, as known as knowledge discovery in databases, is a non-trivial process of revealing the implied, previously unknown and potentially useful information from the massive data. In recently years, the applications of data mining in the field of pharmaceutical research of traditional Chinese medicine have widespread. Especially in the field of the heritage of experiences of na-tional medical masters, data mining plays an important role. In this study, we would expound of the use of methods of data mining in the heritage of experiences of national medical masters, and analyze their advantages and disadvantages, such as association rules, Bayesian networks, neural networks, and decision trees.

Objective To investigate the clinical effect of IFNα combined with mannan peptide in treatment of patients with HBeAg-positive chronic hepatitis B ( CHB ). Methods Eighty HBeAg-positive CHB patients with HBV DNA quantity ranging from 10 to 10 eopies/mL were enrolled and randomized into the treatment group and the control group ( n = 40 for each ). Patients in treatment group were given daily subcutaneous injection of IFNα-2b 5,000,000 U for 52 weeks, and received mannan peptide 10 mg per intravenous injection or 2. 5 mg per intramuscular injection for a total of 2 to 3 treatment courses (12 weeks for each). The control group received only IFNα-2b treatment. Liver function, serum markers of hepatitis B, HBV DNA quantity and blood tests were performed before the treatment and at 2, 4, 8, 16, 26 and 52-week during the treatment; and the adverse effects were recorded. Results The rates for ALT normalization, negative HBsAg, negative HBeAg, HBeAg seroconversion and negative HBV DNA were 91. 8% , 17. 5% , 52. 5% , 27. 5 % and 47. 5% at 52nd week in the treatment group, while those in the control group were 80. 0% , 12. 5% , 30. 0% , 10. 0 % and 25. 0% , respectively. There were significant differences in HBeAg-negative, HBeAg-seroeonversion and HBV DNA-negative rates between two groups (χ2 = 4. 178, 4.021 and 4.381, P < 0. 05 ) , and these indexes in the treatment group were increased to 57. 5% , 30. 0% and 50. 0 respectively at 52nd week after drug withdraw. White blood cells began to be elevated at 4th week and were restored to the normal levels at 8th week in the treatment group, while the count in the control was lower than the normal value even at 52nd week of the treatment with the average of (3.45±1. 18)×109/L. Conclusion Alpha-interferon combined with mannan peptide therapy is effective for patients with HBeAg-positive CHB, which may restore the declined peripheral WBC counts induced by interferon and improve the compliance.

Objective To investigate the effects of acupoint massage on labor analgesia efficacy and it's related clinical factors,so to definite the analgesia mechanism and the relationship between the neurotransmitter dopamine and analgesia mechanism.Methods We choosed patients who have been hospitalized in No.1 hospital from March 2009 to September 2009,and divided them into two groups randomly: observation group and control group.Patients in the observation group were treated with acupuncture massage when the production process went into the active phase.Control group indicated that childbirth was naturally without any treatment.We observed the analgesic effect of point massage and the impact of pressure on the uterine contractions.We tested the dopamine level in the blood by fluorescent spectrophotometry before and afte the acupoint massage.We explored the effects of the point massage on the dopamine level in the puerpera.Results The observation group′s pain decreased more than that of the control group.The intensity of contractions in observation group was decreased more obvious than that of the the control group.The serum dopamine levels was significantly lower than that pre-massage(P

Objective: To observe the effect of electroacupuncture (EA) on nuclear factor kappa B (NF-κB) and nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome in uterine tissues of rats with primary dysmenorrhea (PD), thus to explore the possible mechanism of EA for PD. Methods: Fifty female Sprague-Dawley (SD) rats were randomly divided into a normal group, a model group, an EA at non-acupoint group, an EA at acupoint group and a Western medicine group, with 10 rats in each group. Except for the normal group, rats in the other four groups were treated with estradiol benzoate combined with oxytocin for 11 d to establish PD rat models. From day 1 of the modeling, rats in the normal group and the model group were only properly grasped without any intervention; Guanyuan (CV 4) and Sanyinjiao (SP 6) were selected for EA treatment in the EA at acupoint group; rats in the EA at non-acupoint group were treated with EA at 5 mm away from the acupoints selected above; rats in the Western medicine group were treated with ibuprofen via gavage. Rats in each group were treated for 10-day successively. On the 11th day, except for the normal group, rats in the other groups were intraperitoneally injected with oxytocin (2 U/rat), and the writhing number within 30 min in each group was compared; the pathological changes in rat uteruses were observed by hematoxylin-eosin (HE) staining, and the pathological damage scores were evaluated. Protein expression levels of NF-κB p65, phospho-NF-κB p65, NLRP3, cysteine aspastic acid-specific protease 1 (caspase-1), interleukin (IL)-1β and IL-18 were detected by Western blot. Results: Compared with the normal group, the writhing number increased significantly (P<0.05), and the extensive exfoliation of the endometrium, severe edema, and histopathological score all increased significantly in the model group (P<0.05) as well as the protein levels of NLRP3, caspase-1, IL-1β and IL-18, and the ratio of phospho-NF-κB p65/NF-κB p65 in rat uterine tissues (all P<0.05); compared with the model group, the numbers of writhing reaction decreased within 30 min (P<0.05), the endometrial exfoliation was rare, the edema degree was mild, and the histopathological scores decreased significantly (all P<0.05) in the EA at acupoint group and the Western medicine group; compared with the model group, the phospho-NF-κB p65/NF-κB p65 ratio and the NLRP3, caspase-1, IL-1β and IL-18 protein levels of rat uterine tissues in the EA at acupoint group were significantly lower (P<0.05); compared with the model group, the caspase-1, IL-1β and IL-18 protein levels of the rat uterine tissues decreased significantly (all P<0.05), and the differences in the NLRP3 and phospho-NF-κB p65/NF-κB p65 levels were statistically insignificant (all P>0.05) in the Western medicine group; compared with the Western medicine group, the phospho-NF-κB p65/NF-κB p65 ratio, also the NLRP3, IL-1β and IL-18 protein levels of the uterine tissues decreased significantly in the EA at acupoint group (all P<0.05), while the difference in the caspase-1 level was statistically insignificant (P>0.05); there were no significant differences between the EA at non-acupoint group and the model group in any indicators (all P>0.05). Conclusion: EA at acupoints significantly improves the pain and pathological damages of PD rats. The mechanism may be related to the reduced uterine inflammation via inhibiting NF-κB phosphorylation and NLRP3 activation in uteruses of PD rats.

OBJECTIVETo explore the clinical results of postoperative rehabilitation of patellar fracture by modified seated position of different knee flexion angles, thereby enrich the therapeutic tool of orthopaedics of traditional Chinese and western medicine and provide the evidences for refinement and modernization of traditional Chinese exercise therapy.

METHODSFrom January 2009 to June 2012,90 patients with patellar transverse fractures were treated with open reduction and internal fixation by tension band wire and rehabilitation exercises. There were 52 males and 38 females, aged from 21 to 77 years old with an average of 50.0 years old. Three methods of rehabilitation exercises were adopted in the patients after fractures clinical union. There were 21 males and 14 females in group A (trained by modified seated position of knee flexion about 60 degree), 21 males and 14 females in group B (trained by modified seated position of knee flexion about 30 degree), 10 males and 10 females in group C (trained by walk). The rehabilitation-training time was 1 month. Fracture healing informations were observed by X-ray films. The Böstman patellar fracture function scores were compared before and after training among three groups.

RESULTSPostoperative follow-up time was 6 months. All fractures obtained bone union and the average healing time was 3 months (ranged,2 to 4 months). Böstman patellar fracture function scores in group A, B, C before training were 18.89 ± 2.19, 18.74 ± 2.03, 18.85 ± 2.92, respectively; there was no significant differences in among three groups (P > 0.05). After training, Böstman patellar fracture function scores in group A, B, C were 29.40 ± 1.14, 26.09 ± 3.86, 25.70 ± 4.09, respectively; group A was highest than other two groups; and there was no significant differences between group A and group B.

CONCLUSIONModified seated position of knee flexion about 60 degree was practical and effective training in postoperative rehabilitation for the treatment of patellar fracture, it can obtain the better clinical results than other training method such as walk or modified seated position of knee flexion about 30 degree.
