OBJECTIVETo discuss the anti-inflammatory mechanism of sinomenine on inflammatory media in joint of adjuvant arthritis rats.

METHODRats were randomly divided into the normal group and the model group, the prednisone group, the small, medium, large of sinomenine group (30, 60, 120 mg x kg(-1)). Except for the rats in the normal group, animals were modeled to adjuvant arthritiswith freund's complete adjuvant. The arthritis index (AI) and the swelling degree of paws were recorded, and the activity of IL-1, TNF and the levels of NO, PGE2 in joint fluids of secondary arthritis were determined.

RESULTCompared with the normal group, the activity of IL-1, TNF and the levels of NO, PGE2 in joint fluids of secondary arthritis were increased significantly in the model group (P < 0.05). Compared with the model group, it was shown to exert a dramatic inhibitory effect on secondary reaction of freund's adjuvant arthritis of rats, and the activity of IL-1, TNF and the levels of NO, PGE2 in joint fluids of secondary arthritis were significantly decreased in the sinomenine group (P < 0.05).

CONCLUSIONSinomenine has a remarkable treatment effect on RA. It is via NO to inhibit the activity of cytokines and decrease the level of inflammation mediators, which may be one of its curing RA mechanism.

Short tandem repeats (STRs) have been widely used in forensic sciences such as stain analysis and paternity testing. Although most of STR typing could give the reliable and clear results, some unusual typing have been observed in forensic practice. The anomalous typing could result from a lot of causes, including DNA genetic variation, poor quality or quantity of DNA template, different typing system or method, nonspecific reaction in PCR or anomalous electrophoresis migration. The unusual results may disturb the right interpretation of STR typing.

OBJECTIVETo study the effects of Salvia miltiorrhiza on treatment of Chlamydia trachomatis salpingitis (CTS) and fibrosis.

METHODA mouse model for CTS was estahlished in C3H/He by intravaginal inoculation. after 3 weeks mice were randomly divided into 3 groups. Only Azithromyxin was given orally, Azithromyxin and early S. miltiorrhiza given, or Azithromyxin and later S. miltiorrhiza given. After 10 weeks, observe the change of oviduct of mice, observe the histopathologic change and analysis collagen histochemical index.

RESULT3 Treatment groups induce tubal occlusion and hydrosalpinx decreased and the collagen histochemical index decreased significantly than those of no treatment given (P < 0.05). Early S. miltiorrhiza given group induce tubal occlusion and hydrosalpinx decreased and the collagen histochemical index decreased significantly than only Azithromyxin group or later S. miltiorrhiza given group (P <0.05).

CONCLUSIONWhen we treat CTS genital infection with Azithromyxin, if we can give S. miltiorrhiza treatment as early as possible, it may decrease tubal occlusion and hydrosalpinx. significantly inhibit fibrosis maybe one of its pharmacologic mechanismin.

OBJECTIVETo explore the efficacy and determine the risk factors of survival for recurrent hepatocellular carcinoma(HCC) treated by percutaneous radiofrequency ablation (PRFA).

METHODSFrom January 1999 to December 2008, 82 patients with recurrent HCC, with the diameter less than 7 cm for solitary tumor, or the largest tumor less than 5 cm for multiple tumors(the number of tumors less than 3), were treated by PRFA. The significance of 12 clinical or pathological variables in the risk factors of overall survival were assessed.

RESULTSThe overall survival 1-, 3-, and 5-year survival rates were 75.8%, 43.9% and 34.5% (from the date of PRFA), and 95.1%, 63.2% and 46.6% (from initial hepatectomy), respectively. Univariate analysis indicated that tumor size before initial hepatectomy, recurrence interval from initial hepatectomy, number of recurrent tumors, diameter of largest recurrent tumor, serum glutamyl transpeptidase (GGT) and serum albumin (ALB) level were significant prognostic factors (P < 0.05, Kaplan-Meier Log-rank test). Multivariate analysis showed recurrence interval from initial hepatectomy, diameter of largest recurrence tumor, serum GGT and ALB level were significant prognostic (P < 0.05).

CONCLUSIONPRFA is effective for recurrent HCC. Recurrence interval from initial hepatectomy, diameter of largest recurrent tumor, serum GGT and ALB level are significant prognostic factors.

OBJECTIVETo explore the associations between fasting serum lipids and high-sensitivity C-reactive protein (hsCRP).

METHODSSerum triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and hsCRP were measured in residents of Chengdu, China. Subjects with potential factors which might influence lipids and hsCRP were excluded, 580 subjects [mean age (62.3 ± 6.6) years; male: 58.7%] were finally recruited by random sampling methods.

RESULTSThere was a weak positive relationship between TG and hsCRP (r = 0.108, P = 0.01) and a weak negative relationship between HDL-C and hsCRP (r = -0.197, P < 0.001), this was also true in the sub-group with BMI < 24 kg/m(2) (r = 0.236, -0.140 respectively, all P < 0.001). In subjects with BMI < 24 kg/m(2), the hsCRP concentration was significantly higher in subjects with higher TG or lower HDL-C (all P < 0.05). hsCRP increased in proportion with the degree of dyslipidemia. After adjusting for gender, age, TC, LDL-C, fasting blood glucose, systolic blood pressure, diastolic blood pressure, history of hypertension and diabetes, smoking and alcohol drinking, logistic regression analysis showed that the odds ratio for increased hsCRP was 1.970 in subjects with either increased TG or lower HDL-C (P = 0.105) and 9.098 in subjects with both higher TG or lower HDL-C levels (P = 0.031). However, the observed relationship between TG, HDL-C and hsCRP in subjects with BMI < 24 kg/m(2) could not be observed in subjects with subjects with BMI > 24 kg/m(2) despite significant more cardiovascular risk factors in these subjects.

CONCLUSIONSA weak positive correlation between TG and hsCRP as well as a weak negative correlation between HDL-C and hsCRP was evidenced in the whole cohort suggesting dyslipidemia might be related to enhanced inflammatory status. However, this relationship is not observed in subjects with BMI > 24 kg/m(2) despite existence of more cardiovascular risk factors in these subjects.

OBJECTIVETo assess the clinical effect and safety of the Chinese medicine Longbishu Capsule combined with mesylate doxazosin in the treatment of benign prostatic hyperplasia (BPH) of the kidney deficiency and blood stagnation type.

METHODSThis was a randomized, double-blind, double-simulation control study. We equally assigned 60 men diagnosed with BPH of the kidney deficiency and blood stagnation type to an experimental and a control group, the former treated with mesylate doxazosin plus Longbishu Capsule and the latter with mesylate doxazosin plus placebo. We compared the International Prostate Symptom Score (IPSS), quality of life (QOL), Chinese symptom score (CSS), maximal urinary flow rate (Qmax), and prostate volume between the two groups of patients before and after 6 months of medication.

RESULTSAfter treatment, there were 5 cured cases, 13 markedly effective cases, 9 effective cases, 1 ineffective case, and 2 eliminated cases in the experimental group, as compared with 2 cured cases, 8 markedly effective cases, 10 effective cases, 7 ineffective cases, and 3 eliminated cases in the control group. The total effectiveness rate was obviously higher in the former (96.4%) than in the latter (74.1%). IPSS, Qmax, and CSS were improved in both of the groups after medication, even more significantly in the experimental than in the control group (IPSS: 15.22 ± 2.98 vs 18.15 ± 5.88, P <0.05; Qmax: [13.56 ± 2.26] ml/s vs [11.78 ± 2.97] ml/s, P <0.05; CSS: 6.18 ± 2.13 vs 9.52 ± 3.15, P <0.05). Because of the difference in the QOL score between the two groups at the baseline (P = 0.038 <0.05), no more comparison was made in this aspect after treatment.

CONCLUSIONThe combination of Longbishu Capsule with mesylate doxazosin is safe and effective for the treatment of BPH.

OBJECTIVETo investigate the correlation of International Prostate Symptom Score (IPSS) with the levels of interleukin-8 (IL-8) and cyclooxygenase-2 (COX-2) in the prostate tissue and expressed prostatic secretion (EPS) in patients with benign prostatic hyperplasia (BPH) complicated by prostatitis.

METHODSWe divided 80 BPH patients to be treated by transurethral resection of the prostate (TURP) into a simple BPH group (n = 30) and a BPH with prostatitis group (n = 50) based on the pathologic features. We statistically analyzed IPSS and the levels of IL-8 and COX-2 in EPS before surgery and the IL-8 and COX-2 levels in the prostate tissue after surgery.

RESULTSIPSS was positively correlated with the IL-8 and COX-2 levels in the prostate tissue and EPS of the BPH patients, moderately in the simple hyperplasia group (r > 0.5) and highly in the other (r > 0.8). The levels of IL-8 and COX-2 in the prostate tissue and EPS were significantly higher in the BPH with prostatitis group than in the simple BPH group (P < 0.05).

CONCLUSIONThe levels of IL-8 and COX-2 in EPS indirectly reflect those in the prostate tissue. IPSS and the levels of IL-8 and COX-2 in EPS can help determine whether BPH is complicated by histological prostatic inflammation.

OBJECTIVETo evaluate the efficacy of sublingual immunotherapy (SLIT) with dermatophagoides farinae drops in patients with allergic rhinitis (AR).

METHODSTwo hundred and six patients with AR aged from 4 to 60 years were included in this study. Among them, 123 patients completed more than one year treatment, the number of patients completed one year, one year and a half, two years were 61, 41, 21 cases. Rhinitis symptom scores and medication scores of the three groups before and after treatment were compared. And rhinitis symptom scores and medication scores of patients with one year drug withdrawal after one and two years treatment were aslo compared.

RESULTSAfter SLIT one year, one year and a half, two years treatment, the symptoms in these patients were significantly improved compared with before. The symptom scores (x±s) were reduced from 6.00±2.27, 7.39±1.99 and 6.29±2.14 to 2.95±1.82, 3.28±2.58, 2.48±1.99. The differences were statistically significant (t value was 8.19, 10.29, and 5.97, all P<0.01). The proportion of patients without drug treatment of the three group were 68.9%, 73.2% and 80.9%, there was statistical significance before and after treatment in every group (value was 50.391, 43.619, 27.776, all P<0.01). Symptom improvement of sneezing, runny nose, nasal congestion, nasal itching were similar after one year, one year and a half, two years SLIT treatment, the differences were not statistically significant (F values were 1.200, 1.276 and 2.333, all P>0.05). The proportion of patients without drug treatment in the group which stopped medication one year after two year SLIT (76.2%) was higher than group stopped medication one year after one year SLIT (61.3%). There was no statistical significance (χ2=1.263, P>0.05).

CONCLUSIONThe dust mite drops can relieve symptoms after one year treatment, but the proposed two years treatment is important for the consolidation of improved symptoms, especially for the effect of reducing the use of symptomatic medication.

OBJECTIVETo observe the effects of Qiangjing Tablets (QJT) on the semen quality and Fas/FasL signaling pathway in male SD rats with infertility.

METHODSModels of infertility were made in 50 male SD rats by intragastric administration of Tripterygium (GTW) for 3 weeks, and another 20 rats were taken as blank controls. Then 40 successfully established rat models were randomly divided into four groups, model control, low-dose QJT, medium-dose QJT, and high-dose QJT, the latter three groups treated intragastrically with QJT at 58 mg, 105 mg, and 233 mg per kg of the body weight per day, respectively. After 4 weeks of medication, the rats were killed for examination of semen quality and determination of the expression of the apoptosis factor FasL in the testis tissue.

RESULTSCompared with the blank controls, the model rats showed significant decreases in sperm concentration ([71.99 ± 9.72] vs [10.94 ± 3.58] x 10⁶/ml, P < 0.01), motility ([48.95 ± 4.10] vs [9.31 ± 5.79]%, P < 0.01), and viability ( [82.06 ± 6.16] vs [24.03 ± 6.93]%, P < 0.01). In comparison with the model controls, the rats in the QJT groups exhibited remarkably increased sperm concentration, motility, and viability, more significantly in the high-dose group ([59.66 ± 4.53] x 10⁶/ml, [35.45 ± 5.21] %, and [61.97 ± 9.75]%) and medium-dose group ([40.89 ± 4.90] x 10⁶/ml, [24.41 ± 4.79]%, and [60.06 ± 10.62]%) (P < 0.05 or P < 0.01). The expression of FasL was markedly reduced in the low-, medium-, and high-dose QJT groups (0.5215 ± 0.0189, 0.5371 ± 0.0364, and 0.4556 ± 0.0215) as compared with that of the model controls (0.5989 ± 0.0448 ) (P < 0.05 or P < 0.01).

CONCLUSIONBy upregulating the Fas/FasL signaling pathway, Tripterygium glycosides may induce the apoptosis of spermatogenic cells and reduce sperm concentration, motility and viability, resulting in infertility. The Chinese medicine Qiangjing Tablets can improve the reproductive function of male rats by decreasing the expression of the apoptosis factor FasL in the testis.
