Objective:To evaluate the clinical efficacy and safety ofHJ-RY-1 therapeutic pad ofsoft stone in treating osteoarthritis.Methods:Patients with osteoarthritis with syndrome ofqi stagnancy and blood stasis were enrolled according to the diagnostic criteria and the evaluation standard ofcurative effect in Instruction Principle ofClinical Research ofNew Chinese Medicines, and were randomly divided into experimental group(treating by HJ-RY-1 therapeutic pad ofsoft stone) and the control group(treating by the paster offar infrared bioactive ceramics).Put them respectively on the afflicted part for more than 12 hours a day, and the treatment course ofboth groups lasted 14 days.The main turnover was determined by the improvement of6 clinical parameter indices and the incidence rate ofwhole curative effect and side effect after a treatment of7 days and 14 days.Results:72 patients were randomly equally divided into two groups, and received predetermined interveneing therapy.There were similar baseline characteristics and comparabilities between them.Totally 68 patients finished 2 weeks follow-up observation and 4 cases were missed(33/36 in experimental group;35/36 in the control group).1 weeks later, there were no significant difference in clinical situation and overall curative effect between two groups.But after two weeks interveneing therapy, there were significant difference on activity pain(t-value was 3.3104), the joint movement range(t-value was 3.1596), self-sensation(t-value was 2.5521) and overall curative effect(t-value was 3.5694) between them(P

Objective To explore the correlation between the joint detection of cholinesterase(CHE),alpha-L-fucosidase(AFU) and alpha-fetoprotein(AFP)and primary hepatic cancer(PHC).Methods 56 cases of patients with PHC(PHC group),52 cases of patients with liver cirrhosis(LC group)and 60 cases of healthy individuals(control group)were enrolled in this study,and serum levels of CHE,AFU and AFP were detected and statistically analysed.Results Serum levels of CHE in patients with PHC were negatively correlated with levels of AFU and AFP(correlation coefficient was -0.889 and -0.797 respectively,P <0.05),the ser-um levels of CHE in patients with LC were also negatively correlated with levels of AFU and AFP (correlation coefficient was-0.598 and -0.653 respectively,P <0.05).The positive rates of joint detection of CHE,AFU and AFP in PHC group and LC group were higher than that in the control group,had statistically significant differences(P <0.05 ).Conclusion CHE,AFU and AFP are sensitive indicators of liver lesions,and the joint detection could provide reference value for diagnosis and monitoring pro-gression of PHC.

Objective To investigate the expression of survivin/Human leukocyte antigen class I ( HLA-Ⅰ) proteins and its physiological significance in clear cell renal cell carcinoma ( CCRCC ) . Methods Immunohistochemistry was used to analyze survivin/HLA-Ⅰ protein expression in 90 cases of CCRCC and 10 normal tissues to study relationships with clinical symptoms and disease prognosis . Resutl s The level of survivin protein expression was found to be significantly higher in CCRCC tissues 82.2%( 74/90) than in normal tissues( 0/10).However, the relative amount of HLA-Ⅰprotein in colorectal cancer tis-sue was also found to be significantly lower 67.8%(61/90) than in normal tissues 90%(9/10).Survivin expression was associated with tumor grade , stage,and lymph node metastasis ( P=0.000, P=0.016, and P=0.001, respectively ) .Conversely , lost HLA-Ⅰexpression did not have any associations with clinicopath-ological data (P>0.05).Survivin negative patients (25.0%, 4/16) had a higher tumor-free survival rate than patients (52.7%, 39/74)with survivin expression (P=0.037).Patients (27.6%, 8/29) with normal HLA-Ⅰlevels had a higher tumor-free survival rate than those ( 60.7%, 37/61) with reduced HLA-Ⅰlev-els (P=0.020).The univariate and multivariate analyses indicated that expression of survivin and HLA indi -vidually and in combination were independent predictors for CCRCC patient survival . Conclusions Over-expression of survivin but reduced HLA-Ⅰ expression is associated with CCRCC development and progres-sion.

Objective To explore more suitable calculation method of the insulin dosage in insulin hypoglycemia-growth hormone stimulation test(insulin tolerance test, ITT). Methods Fifty-six subjects suspected of growth hormone deficiency were divided into primary and secondary onset groups. All the patients took oral glucose tolerance test and ITT. Homeostasis model of assessment for insulin resistance index ( HOMA-IR) and insulin sensitivity index ( ISI), area under insulin curve ( AUCINS ) and the area under glucose curve ( AUCPG ) were calculated. The insulin dosages during ITT between two groups were compared and the main factors influencing the insulin dosage were analyzed. Results There was no difference in the insulin dosage during ITT between primary and secondary groups. The actual dosage of insulin in this cohort study revealed a significant difference from the initial insulin dosage recommended by the guideline. Multiple linear regression analysis found that AUCINS and body mass index were the independent factors affecting the insulin dosage. Then the optimized coefficient of ITT ( γ) were found. Conclusion The insulin dosage used in our study was inconsistent with the guidelines-recommended ones. In order to make ITT more efficient and safer, a more optimized calculation method to improve the successful rate of insulin-induced hypoglycemia in ITT is proposed.

Objective To evaluate the effects of rigorous surveillance and retroperitoneal lymph node dissection (RPLND) in the treatment of low-risk patients with clinical stage Ⅰ nonseminomatous germ cell testicular tumors (NSGCT) after radical orchiectomy.Methods The data of 71 patients with clinical stage Ⅰ NSGCT were analyzed retrospectively in Hunan Provincial Tumor Hospital,Xiangya Third Hospital of Central South University and Hunan Provincial People's Hospital between Feb,2001 and Apr,2012.Excluding lymphatic and vascular invasion,percentage of embryonal carcinoma＞50％ and increasing tumour markers (AFP/β-HCG) following orchiectomy,46 low-risk patients out of 71 patients with clinical stage Ⅰ NSGCT were selected and divided into rigorous surveillance group (30 cases) and RPLND group (16 cases) according to different therapeutic methods after radical orchiectomy.Univariate analysis was used to confirm variables associated with disease progression,and the disease free survival rates (DFSR) were compared by using Kaplan-Meier analysis.Results Five cases were lost,and 41 cases were followed up for an average of 61 months (range,15-147 months),with 58 months in rigorous surveillance group (range,19-147months) and 65 months in RPLND group (range,15-144 months).The survival rate was 100％ in 2 groups.The DFSR was 89％ (24/27) and 86％ (12/14),respectively,and there was no significant difference between the 2 groups (x2 =0.08,P=0.78).The DFSR was 83％ in patients with small amout of embryonal (percentage of embryonal carcinoma ＜ 50％),and 92％ in patients without embryonal carcinoma,and there was no significant difference between the 2 groups (x2=1.07,P=0.30).Also there was no significant difference between the patients less than 15 years and patients more than 15 years (x2=1.59,P =0.21).Conclusions There is no significant difference in recurrence rate and DFSR between rigorous surveillance group and RPLND group.Low-risk patients with clinical stage Ⅰ NSGCT may achieve satisfactory prognosis with surveillance after radical orchiectomy.

Objective To raise the awareness of adrenal Castleman′s disease by analyzing the clinical features and management of a patient with adrenal Castleman′s disease. Methods A case of adrenal Castleman′s disease of our hospital was retrospectively analyzed, including clinical feature, laboratory findings, pathology, treatment, and follow-up. All the data and pertinent literatures were reviewed and analyzed. Results An incidentaloma measuring 4. 8 cm × 6. 3 cm in the right adrenal gland was observed in a 30-year-old men in a ultrasonography examination performed due to a medical check-up. Laboratory analysis showed that the lesion was not hyperfunctioning. The patient subsequently underwent an exploratory laparotomy. Pathological examination revealed retroperitoneally localized Castleman′s disease of the hyaline vascular type. Conclusion Adrenal Castleman′s disease is a rare cause of lymph node hypertrophy, and it is necessary to keep in mind the possibility of its occurrence and take it into consideration in the differential diagnosis of any solitary, heterogeneous, and hypervascular retroperitoneal mass. The proper cooperation between the clinician and pathologist allows early diagnosis and suitable therapy.
