OBJECTIVETo study the antalgic and antiphlogistic functions and mechanism of ronggudingtong (RGDT) plaster (traditional Chinese medicine).

METHODSThe painful models were established with hot plate test or acetic acid writhing and the inflammatory models were established with daubing dimethylbenzene on auricle or injecting formaldehyde in toe or synovial envelope to study the antalgic and antiphlogistic functions of RGDT Plaster. The total protein and leukotriene B4(LTB4) in inflammatory exudate were detected to investigate the antalgic and antiphlogistic mechanism of RGDT plaster. The mice were randomly divided into different groups (n = 11), on the basis of drug using, the indexes of pain threshold, swelling degree were observed. Sixty-six mice were used to establish gasbag synovitis model and randomly divided into normal control group,model control group, positive control group (Voltaren gel 0.8 mg/d)and low/medium/high dosage RGDT plaster treating groups(30 mg/d, 60 mg/d, 120 mg/d).

RESULTS30 mg/d, 60 mg/d,120 mg/d RGDT plaster could upgrade the pain thresholds, remit auricular and foot swelling (P < 0.05, P < 0.01), and degrade total protein and LTB4 in inflammatory exudates (P < 0.05, P < 0.01).

CONCLUSIONRGDT plaster has some antalgic and antiphlogistic functions, and one of the mechanisms is depressing synthesis of LTB4.

OBJECTIVETo investigate the clinical significance of plasmic L-plastin level in patients with colorectal cancer.

METHODSFrom March 2008 to March 2009, plasma samples were collected from 40 patients and 40 healthy controls. Plasmic L-plastin level was measured by ELISA kit and was compared to TIMP-1.

RESULTSPlasmic L-plastin level in patients with colorectal cancer was higher than that in healthy adults (1.662±0.386 vs. 0.485±0.085 μg/L, P<0.01). The sensitivity of L-plastin in the diagnosis of colorectal cancer was 67.5%, and the specificity was 80.6%. The Youden index was 0.481 and AUC was 0.772 (P<0.01). Plasmic L-plastin levels were associated with the tumor size (P=0.006), serosal penetration (F=4.687, P<0.05) and lymphatic metastasis (P<0.01). Compared to plasmic TIMP-1 level, L-plastin showed the same capability in indicating the depth of tumor. The specificity of L-plastin was better in indicating lymphatic metastasis (86% vs. 58%, χ2=4.2, P<0.05).

CONCLUSIONSPlasmic L-plastin level may serve as a potential marker in colorectal cancer.

OBJECTIVETo observe the efficacy and safety of Jingui Shengqi Pill in treating partial androgen deficiency in aging males (PADAM), and to explore the new approach in improving the quality of life in PADAM patients.

METHODSForty patients with PADAM were treated with JSP, the efficacy was evaluated with international index of erectile function (IIEF) scoring, PADAM questionnaire scoring, hormone, prostatic specific antigen (PSA), etc., and the data before treatment were compared with those after treatment in the same group.

RESULTSAfter 3 months of treatment, PADAM scoring and IIEF scoring were all significantly improved. Symptoms regarding physical ability, vasomotion, and psychical and mental condition all got improved more markedly than symptoms regarding sexual hypofunction. The serum level of testosterone was 3.85 +/- 0.36 before treatment and 5.02 +/- 0.83 after treatment (P < 0.05); luteinizing hormone of 7.33 +/- 2.14 and 4.84 +/- 1.43 (P < 0.01), follicle-stimulating hormone of 10.22 +/- 4.48 and 6.47 +/- 3.28 (P < 0.01), respectively. The level of PSA failed to change significantly (1.94 +/- 0.55 and 2.06 +/- 0.47, P > 0.05).

CONCLUSIONJSP is effective and safe in treating PADAM, the mechanism of it is different from supplementing extrinsic androgen. It may have produced the effect by means of favorably regulating the condition of sex hormone to improve the balance of pituitary-sex gland axis, so it has more extensive clinical application.

Objective To evaluate the feasibility of different kinds of surgeries to treat hypopharyngeal carcinoma and investigate the methods to conduct one-stage repair after hypopharyngeal carcinoma removal. Methods Thirty nine cases of hypopharyngeal carcinoma were treated from May 2000 to Mar 2007, of which 27 were originated from pyriform sinus, 8 from postcricoid and 4 from posterior pharyngeal wall. One-stage reconstruction for hypopharyngeal and esophageal defect was done with simple and less-damaged hypopharyngeal plasty by local sewing, infrahyoid muscle flap, pectoralis major flap and supplement of esophagus by stomach. Results The defect of 18 cases was repaired by sternohyoid muscle flap, including 13 from pyriform sinus, 4 from root of tongue and 1 from posterior pharyngeal wall. Seven were repaired by substitute of esophagus by stomach, 5 by local sewing, 4 by cervical flap and 2 by pectoralis major myocutaneous flap. All the patients were successfully followed up during the survival days. Half of the cases suffered from slight deglutitory disorder after operation and recovered soon, while 2 cases were still with worse deglutitory function. All the cases were recovered with laryngeal function, and 21 cases were decannulated with normal respiration and voice, and 18 with cannula. Thirteen cases survived for more than 3 years after operation and 5 cases more than 5 years, while 14 cases died within 1 year. Thirteen cases were carried out another operations for local recurrence or metastases of lymph nodes, one of whom experienced 6 operations. The estimated 3-year survival was 43.3% (13/30), and 5-year survival was 37.5%(3/8). Conclusion Hypopharyngeal carcinoma with different site and stage can be treated by different methods, and one-stage reconstruction can be done to repair the defect of pharynx and esophagus with satisfactory functional restoration and prognosis.

Objective To know the related factors of the coping styles of nursing students in different educational systems. Methods 290 nursing students with different educational systems were selected, then interviewed for the coping styles and general states by questionnaires. And the datum were analyzed with the SPSS 13.0. Results The score of active coping was (42.00±20.57), and the score of negative coping was (34.00±13.24) in 290 nurses. Among the different demographic characteristics, sex, educational system, origin, whether or not only child and culture degree of parents had inlfuece to active coping, and there were significant differences for the coping styles (P<0.05). Conclusions In order to cultivate the favorable coping style, the psychic-training and the consulation should be done uninterrupted, the lecture of mental health education and the the coping style training should be given regularly for the different students.

Klinefelter’s syndrome (KS) is the most common sex chromosome disease in men. Classical features of the syndrome include a eunuchoidal body habitus, small testes and hypergonadotrophic hypogonadism. There has been an increased risk of diabetes mellitus and autoimmune disease for KS patients. This paper reports a case of KS in association with type 1 diabetes mellitus. The patient was a 21-year-old man, who has been confirmed by absolute insulin deficiency and positive IA-2 autoantibody. The hyperinsulinemic euglycemic clamp test indicated his insulin sensitivity in normal range, and his blood glucose was controlled well by the insulin therapy.

OBJECTIVETo assess and compare the Human Papillomavirus (HPV) detection efficiency and the potential clinical utility of PCR sequencing-based technology.

METHODSFour HPV consensus primer sets (GP5+/6+, MGP, MY09/11, and PGMY09/11) were used in order to amplify a broad spectrum of HPV types for HPV infection in 325 cervical samples and the PCR products were sequenced afterwards for the HPV genotyping.

RESULTSThe HPV-positive rate was 75.4%, of which 35.5% harbored more than one HPV genotype. A total of 36 different genotypes was found, with HPV 16 (24.1%) being the most prevalent, followed by HPV 58 (13.3%) and HPV 52 (9.6%). There were substantial to almost perfect agreements between different primer sets regarding HPV detection efficiency, with the kappa value varying from 0.751 to 0.925, MGP, and PGMY09/11 were the most effective in detecting multiple infections (P < 0.001). With each of the primer sets, a board range of HPV types could be identified, though there were several differences for a few genotypes.

CONCLUSIONThe substantial agreement between PCR-sequencing and HC2 for the detection of high-risk HPV (kappa=0.761) indicated that PCR-sequencing is also suitable for routine HPV screening.

Anthracycline-Taxane chemotherapy is widely used in neoadjuvant treatment for breast cancers. However, there is limited data reported in patients with triple negative breast cancer (TNBC). Here, we evaluated the pathologic responses and survival of neoadjuvant epirubicin and taxanes chemotherapy in patients with locally advanced TNBC to provide some useful information for clinical practice. A total of 43 patients with locally advanced TNBC were enrolled in this study. Patients were administered with epirubicin 75 mg/m(2) plus paclitaxel 175 mg/m(2) or docetaxel 75 mg/m(2) every 3 weeks for at least 2 cycles. The primary endpoint was pathologic complete response (pCR), which was defined as no residual invasive cancer, or only carcinoma in situ in both the excised breast and axillary lymph node, while relapse-free survival (RFS) and overall survival (OS) were secondary endpoints. Thirty-nine (90.7%) patients were at clinical stages IIB-IIIC. Thirty-seven (86%) completed 4-6 cycles of preoperative chemotherapy, and objective response rate (ORR) was 81.4% (35/43). Forty-two patients underwent radical surgery subsequently. The pCR rate was 14.3% (6/42). The most common adverse events in neoadjuvant chemotherapy were nausea/vomiting (88.4%, 38/43) and neutropenia (88.4%). After a median follow-up period of 34.0 months, 3-year RFS and OS rate was 53.6% and 80.1%, respectively. All events of recurrence and death occurred in non-pCR patients, in whom the 3-year RFS and OS rates were 44.3% and 76.6%, respectively. This study suggest that neoadjuvant chemotherapy with epirubicin plus taxanes has a relatively low pCR rate and high early recurrence risk in locally advanced TNBC, which indicates the necessity for more efficacious treatment. Further study is needed to validate these results.

OBJECTIVETo investigate the histogenetic origin of primary central nervous system diffuse large B-cell lymphoma (DLBCL) with respect to the stage of B-cell differentiation, and identification of the relevant prognostic markers.

METHODSImmunohistochemical staining (EnVision method) for CD10, bcl-6, MUM-1, CD138 and FOXP1 antigens was performed on 47 paraffin-embedded sections.

RESULTSCD10, bcl-6, MUM-1 and FOXP1 expression in the tumor cells were 6.4%, 53.2%, 91.5% and 93.6% respectively. There was no expression of CD138 in all the cases. Among the 47 patients, 43 cases (91.5%) showed an activated B-cell-like (ABC) phenotype: 21 (44.7%) were bcl-6+ and MUM-1+, suggesting an "activated germinal center (GC) B-cell-like" in origin; 22 (46.8%) were exclusively MUM-1+, suggesting an "activated non-GCB" in origin. No significant correlation of the classification and FOXP1 expression found on the outcome (P=0.279 and P=0.154).

CONCLUSIONSMost primary central nervous system DLBCL are shown belonging to the ABC subgroup, suggesting that primary central nervous system DLBCL is quite similar to a DLBCL subset, which is derived from late GC to early post-GC B cell. The classification and FOXP1 expression do not show prognostic value in primary central nervous system DLBCL.
