Objective To investigate the expression of osteopontin and matrix metalloproteinase-9 (MMP9),and the relationship of osteopontin and MMP9 in malignant melanoma.Methods Expression of osteopontin and MMP9 was measured by immunohistochemical SP method in 23 patients with primary cuta- neous malignant melanoma,17 patients with metastatic melanoma and 20 patients with pigmented nevus. Results Osteopontin and MMP9 were expressed respectively in 87.5% and 75.0% of 40 malignant melanoma specimens,15.0% and 10.0% of 20 pigmented nevus specimens.The expression of both osteo- pontin and MMP9 was significantly higher (both P＜0.05) in malignant melanoma than in pigmented ne- vus.There was no correlation between the expression of osteopontin and MMP9,with age,sex,lymph node metastasis or location of lesions (P＞0.05).Twenty-nine cases were positive for both osteopontin and MMP9,4 negative for either osteopontin or MMP9.Conclusion Both osteopontin and MMP9 were over- expressed in malignant melanoma,but neither was related to lymph node metastasis.

Objective: To observe the clinical efficacy of herb-partitioned spreading moxibustion at Baliao points plus climen for diminished ovarian reserve (DOR). Methods: A total of 60 patients with DOR were randomized into a spreading moxibustion group and a Western medicine group by the random number table method, with 30 cases in each group. The Western medicine group was treated with climen, starting from the 5th day of the menstrual cycle for 21 d. The spreading moxibustion group was treated with herb-partitioned spreading moxibustion at Baliao points on the basis of the medication in the Western medicine group, 1 h per time, once a week. The treatment was performed for 1 month as one treatment course in both groups, for 3 courses in total. The serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) in the patients were measured before and after treatment. The peak systolic velocity (PSV) and resistance index (RI) were also detected. The traditional Chinese medicine (TCM) symptom score was evaluated. The clinical efficacy was evaluated after treatment. Results: The total effective rate in the spreading moxibustion group was 93.3％, which was significantly higher than 80.0％ in the Western medicine group, and the difference between the groups was statistically significant (P<0.05). After treatment, the TCM symptom scores, the serum FSH levels, FSH/LH ratios and RI in both groups decreased, and the intra-group differences were all statistically significant (all P<0.05). The serum E2 level and PSV increased compared with those in the same group before treatment, and the intra-group differences were statistically significant (all P<0.05). After treatment, the TCM symptom score, the serum FSH level, FSH/LH ratio and RI in the spreading moxibustion group were lower than those in the Western medicine group, while the serum E2 level and PSV were higher than those in the Western medicine group, and the differences between the groups were statistically significant (all P<0.05). Conclusion: Herb-partitioned spreading moxibustion at Baliao points plus climen can produce valid therapeutic efficacy for DOR. It can improve the clinical symptoms, regulate serum hormone levels and increase ovarian blood perfusion, thus improving ovarian reserve function, producing more significant efficacy than climen alone.

The present condition in the acupoint term translation was analyzed and its existent problems in this area were discussed in this paper. The authors suggested that in translating the terms of acupoints, the translation on the meaning of the acupoints should be added, in this way, it can not only keep the integrity in acupoint translation, but also make the inheritance of the Chinese precious culture of Traditional Chinese Medicine further available.

Objective To explore the factors influencing the premarital medical examination in Chinese population and to discuss the related possible intervention strategies.Methods Data were collected through self-designed questionnaires on 2572 newly married respondents,selected under a stratified randomized sampling method,at Marriage Registration Office in 12 counties in Zhejiang province.Predictive factors were derived from the integrating complementary constructs of Health Belief Model,Theory of Reasoned Action as well as individual demographic characteristics.Multiple logistic multilevel analyses was used as the main statistical method,with individuals as the ' low' and counties as the 'high' levels.Results Behaviors on premarital medical examination showed a clustering trait at the county level (P=0.018) and variance partition coefficients (VPC) of each variables was between 15.40％ and 17.58％.There were no statistical significances found in the rates of premarital medical examination among gender,age,residence of Household Registration,education,income,health insurance and history of premarital medical examination.However,significant correlation was seen on occupation of the respondents.The rate of premarital medical examination among the respondents who had not attended medical examination during the last six moths was 1.31times (95％ confidence intervals,1.05 -1.65 ) more than those who had,with OR (odds ratio) as 1.51 (95％CI:1.14-2.00) for the pregnant respondents in their first marriage and 0.35 (95％CI:0.23-0.51 )for remarried respondents,compared with women at first marriage but remained unpregnant.Regarding premarital medical examination,the respondents reported greater benefits,less barriers,greater positive behavioral attitudes and normative beliefs to it,with an ORs as 2.32 (95％ CI:1.18-4.60),0.71 (95％CI:0.57-0.90),1.69 (95％CI:1.10-2.58) and 1.72 (95％CI:1.34-2.20)respectively,but with no significant association with perceived susceptibility,perceived severity and motivation to comply.Conclusion Factors such as individual perceived benefits,barriers,attitudes and normative beliefs etc.,were determinants of premarital medical examination accompanied by minor (16％) influence coming from the geographical environment.

Most drugs need to interact with cell membrane to reach the biological target, so that membrane affinity assay is an important early screening step in drug discovery. However, at present, the traditional oil-water distribution method is still used, a new, simple and accurate method for membrane affinity assay is urgently needed. In this study, according to the colorimetric principle, a new assay model based on polydiacetylene vesicles was optimized through a series of experiments including different concentrations of vesicle solution, temperature, or pH reaction environment. On this basis, tetracaine hydrochloride, 2-methylimidazole and histamine were used as model drugs to measure the membrane affinity constants and verify the between-batch precision of the optimized assay model (relative standard deviation less than 5%). In addition, polydiacetylene vesicles were stable for up to 180 days, demonstrating the potential application of the assay model. This strategy is simple, stable, reliable, with high reproducibility, low cost and easy to promote, which provided a new tool and a new direction for the high-throughput assay of membrane affinity.

OBJECTIVETo analyze the radiological parameters of the conservatively in treating distal radius fracture and investigate whether the final re-displacement can be predicted after primary reduction.

METHODSFrom January 2013 to June 2014,212 patients with distal radial fracture conservatively were treated in our hospital, 107 patients of them were excluded because of their incomplete radiological parameters;the remaining 105 patients were available for radiological were assessed after injury, there were 56 male patients and 49 female patients in this study, the average age of the patients was 51 years old (ranged from 22 to 80 years). According to AO classification, there were 47 cases of type A2 and C1, and 58 cases of type A3, C2, C3. All patients were treated by closed reduction and below-elbow cast immobilization for 4 to 6 weeks. All patients were followed up for 3 to 6 months (means 4.5 months) by X-ray, all fractures were healed. Standard AP and lateral radiographic examination was conducted before reduction and after reduction and bony consolidation,the dorsal angulation and the radial angle were measured at each time point. The linear regression was used for the analysis to find out whether the final re-displacement can be predicted after primary reduction.

RESULTSAmong 105 patients,the significant correlations were found for the dorsal angulation between the reduction time and the end time (r = 0.82) and for the radial angulation between the reduction time and end time (r = 0.85).

CONCLUSIONThe dorsal angulation and the radial angulation after complete healing can be predicted from linear the regression functions. Due to the possibility of predicting the end result, whether the fracture should receive further conservative treatment or surgical treatment can be decided immediately.

OBJECTIVETo study the clinical and pathologic characteristics of poorly differentiated cutaneous angiosarcoma of scalp.

METHODSEight cases of poorly differentiated cutaneous angiosarcoma of scalp were enrolled into this study. The clinical manifestations and histopathologic features were analyzed. Immunohistochemical study for CD31, CD34, factor VIII-related antigen, vimentin, AE1/AE3, CAM5. 2, epithelial membrane antigen and carcinoembryonic antigen was performed.

RESULTSThe mean age of the patients was 69 years. The male-to-female ratio was 5 : 3. The tumor manifested clinically as bruise-like lesion in early phase, indurated erythematous plaque accompanied by nodules, ulcerations and bleeding in advanced phase. Histologically, the tumor was composed of solid sheets of undifferentiated spindle cells which were not easily recognizable as vascular in origin. Nuclear atypia was always present. The tumor cells in all of the 8 cases strongly expressed CD31, factor VIII-related antigen and vimentin. Weak expression of CD34, AE1/AE3 and CAMS. 2 was noted in 2, 4 and 4 cases, respectively. The staining for epithelial membrane antigen, carcinoembryonic antigen and S-100 was negative. Conclusions Angiosarcoma needs to be excluded by histologic examination whenever bruise-like and erythematous lesions occurring on scalp skin of elderly patients. The endothelial origin of the tumor cells can be confirmed with immunostaining for CD31, CD34 and factor VIII-related antigen.

OBJECTIVETo evaluate the impact of recombinant human growth hormone (rhGH) combined with hypocaloric nutrition on nitrogen balance and blood glucose in patients after gastrointestinal operation.

METHODSForty-eight patients undergone abdominal operations were randomly divided into either subcutaneous rhGH (0.15 IU/kg) or placebo (menstruum) injection daily for 7 days postoperatively. These two groups had similar nutritional intakes. Body weight, blood cell count, liver and renal function, plasma albumin, prealbumin, transferrin and fibronectin were measured at day 1 before operation as baseline and day 3 and day 10 after operation by standard laboratory techniques. Nitrogen balance and blood glucose were measured from day 3 to day 9 after operation.

RESULTSAt postoperative day 10, the cumulative nitrogen balance and the level of plasma fibronectin were significantly higher in rhGH group [13.21 g,(104.77+/-19.94) mg/L] than those in placebo group [-6.88 g, (93.03+/-16.03) mg/L] (P<0.05). Furthermore, at day 4 and from day 6 to day 9 after operation, daily nitrogen balance was higher in rhGH group than that in control group (P<0.05). Mean blood glucose level was significantly higher in rhGH group from day 3 to day 6 after operation [(7.68+/-2.15) vs (5.95+/-2.34) mmol/L, P<0.05]. But hyperglycemia could be controlled well by insulin treatment.

CONCLUSIONGrowth hormone combined with hypocaloric nutrition is effective and safe in promoting positive nitrogen balance and protein synthesis in post-operative patients, which is also beneficial to the improvement of nutritional status and prognosis.
