Objective To study the effect of Radix Salviae Miltiorrhizae (RSM), a kind of Chinese Traditional Medicine which can dissolve stasis by activating blood circulation, on proliferation, invasion, adhesion, migration and metastasis of B16-BL6 metastatic mouse melanoma cells and discuss its functional mechanism. Methods The proliferation, adhesion, invasion and migration capacity of B16-BL6 metastatic cells was evaluated by MTT assay, adhesion assay and reconstituted basement membrane invasion and migration assay in vitro respectively. Mouse spontaneous melanoma model was used to study the effect of RSM on metastasis in vivo. Results The extract of RSM bidirectionally adjusted the multiplication of B16-BL6 cells, promoted prominently the adhesion of B16-BL6 to Laminin, inhibited significantly B16-BL6 invading reconstituted basement membrane and the migration of B16-BL6. In the mouse spontaneous melanoma model, it suppressed significantly the volume of lung metastatic nodes but had little effect on the number of lung metastatic nodes. Conclusion The extract of RSM can alleviate the degree of the metastasis of B16-BL6 metastatic mouse melanoma cells, which may be related with inhibiting the B16-BL6 cells invading the extracellular matrix and reducing the migration of B16-BL6 cells.

Objective To investigate the clinical effects and complications of uterine artery embolization (UAE) therapy using different embolic agents in treating uterine adenomyosis. Methods During 2004—2011, a total of 45 female patients with uterine adenomyosis were admmitted to authors’ hospital to receive uterine artery embolization therapy. The embolic agents used in the procedures included domestic iodized oil, sodium alginate microspheres and Embosphere microspheres. The patients were randomly divided into group A (n=15, using domestic iodized oil as embolic agent), Group B (n=13, using sodium alginate microspheres as embolic agent) and group C (n = 17, using Embosphere microspheres as embolic agent). After the treatment, all the patients were followed up for over 2 years, focusing on the observation of the clinical symptoms such dysmenorrheal, changes of MRI signs and severe complications. The results were analyzed and compared among the three groups. Results After UAE, the clinical symptoms such as the degree of dysmenorrhea, menstrual quantity, etc. were improved in all patients. Six months after UAE, the obvious remission rate of dysmenorrheal in group A, B and C was 33.3% (5/15), 30.8% (4/13) and 41.1%(7/17) respectively. Twelve months after UAE, MRI scanning showed that the uterine sizes in group A, B and C were reduced to 49.19%, 48.25% and 50.05% respectively. Follow-up examination at 24 months after UAE showed that recurrence of dysmenorrheal in group A, B and C was seen in 2, 4 and 2 cases respectively, and amenorrhea was seen in 2 cases of group A and one case in group C. Conclusion The use of domestic iodized oil, sodium alginate microspheres or Embosphere microspheres as embolic agents in performing super-selective uterine artery embolization for adenomyosis can effectively relieve the degree of dysmenorrheal, decrease the uterine size. In addition to ovarian dysfunction, the uterine cavity adhesion may be also a possible cause of amenorrhea occurring after UAE may. In order to ensure a similar clinical efficacy, the use of granular solid embolic agent is preferred as its safety is possibly higher than the liquid embolic agents.

BACKGROUND:Longitudinal study of changes in obesity is an important method to explore the etiology, which can provide scientific basis for preventing and control ing obesity.
OBJECTIVE:To investigate the effect of age, observation period and birth cohort on the obesity prevalence of adults in Jiangsu province through the age-period-cohort analysis.
METHODS:20-69-year-old adults in Jiangsu province were col ected as the research objects. The stratified cluster sampling method was used to col ect the obese data in 2000-2010, and analyzed with SAS software. RESULTS AND CONCLUSION:Obesity prevalence of 1946-1950 birth cohort to 1976-1980 birth cohort was gradual y increased (P<0.05) from 2000 to 2010. Obesity prevalence from 1931-1935 birth cohort to 1941-1945 birth cohort was not significantly increased (P>0.05). With the increasing age in each age group of over 25 years old, the risk of obesity was increased gradual y. There were significant differences in the odds ratios between the baseline groups of 20-25 years old and the age groups of over 25 years (P<0.05). Compared with the 1995-1999 birth cohort, the other periods had a slight influence on the obesity prevalence (P>0.05). Compared with 1976-1980 birth cohort, there were no significant differences in the risks of obesity of the birth cohorts after 1951-1955 (P>0.05). But the risk of obesity from 1946-1950 birth cohort to 1931-1935 birth cohort was gradual y significant since the 2000;obesity risks of those born in the different times were different;rural area wil be the key area than 45 years old.

Objective To review the treatment results of intracytoplasmic injection(ICSI) of epididymal or testicular sperm obtained from 38 obstructive azoospermic patients.Methods Sperm was retrieved by percutaneous epididymal sperm aspiration(PESA) or testicular sperm extraction(TESE).Intracytoplasmic injection was performed.The rates of fertilization and clinical pregnancy were evaluated.Control group was set up in which intracytoplasmic injection was performed using sperm of ejaculation.Results Forty-one treatment cycles were performed in the 38 obstructive azoospermc patients.The rates of fertilization and clinical pregnancy were 73.3% and 53.6%.Thirty-three treatment cycles were done in the 31 ejaculatory ones.The rates of fertilization and clinical pregnancy were 75.1% and 48.4%.No significant difference was seen between the two groups.In the obstructive azoospermia group,22 clinical pregnancies were achieved including 13 live deliveries and 3 ongoing pregnancies and 6 miscarriages.In the ejaculatory group,16 clinical pregnancies were achieved including 10 live deliveries and 5 ongoing pregnancies and 1 miscarriages.Conclusions ICSI with PESA or TESE is an effective method for treatment of obstructive azoospermic patients.

The leaves of the plants of one, two and three years old, separately, were collected in July. ANOVA and LSD test were employed in the statistical analysis. The results indicated that flavonoids located mainly in xylem conduit of vein, collenchyma, epidermic cells and cuticle. The data of flavonoids contents under statistical analysis showed that difference existed in the leaves of different parts and different ages. This study provided the reliable scientific material about the analysis of the ecological and the exploitation of the leaves of Apocynum venetom L.

Objective Few reports are seen about the effects of cooling blood and removing stasis on nephrin and podocin . This study was to evaluate the therapy of cooling blood and removing stasis for Henoch -Sch?nlein purpura nephritis ( HSPN) and its ac-tion mechanisms by observing the effects of Danshao Granular Ⅲ on hematuresis , proteinuria and the expressions of nephridial nephrin and podocin in HSPN rats . Methods Twenty-one SD male rats were e-qually randomized to a blank control , an HSPN model , and a Dan-shao group.At 13 weeks after modeling , the animals in the model group were treated intragastrically with distilled water , while those in the Danshao group with Danshao Granular Ⅲtwice daily for 4 weeks. Then, the urinary red blood cell ( RBC) count was examined , the
24 h urinary protein quantity determined , the glomerular mesangial changes observed under the light microscope , the protein expres-sions and distributions of nephrin and podocin detected by indirect immunofluorescence , and their mRNA expressions determined by re-al-time PCR. Results The urinary RBC count and 24 h urine protein quantity were significantly higher in the HSPN model than in the blank control group (26.5/HP vs 0.3/HP and [2.214 ±1.090]g/24 h vs [0.624 ±0.354]g/24 h, both P<0.01).The model rats showed obvious pathological changes in the renal tissue .The urinary RBC count and 24 h urine protein volume were remarkably de-creased in the Danshao group as compared with the models (0.8/HP vs 26.5/HP and [1.000 ±0.651]g/24 h vs [2.214 ±1.090] g/24 h, both P<0.01).The pathological changes in the renal tissue of the Danshao group were reduced in comparison with those of the model group.The protein expression of nephrin was higher in the former than in the latter (65.975 ±14.414 vs 43.520 ±0.632, P<0.01) and so was that of podocin though with no statistically significant difference (P>0.05).The distributions of nephrin and podocin were improved after Danshao treatment .The mRNA expressions of nephrin and podocin were markedly higher in the Danshao group than in the HSPN models (0.530 ±0.089 vs 0.117 ±0.021 and 0.490 ±0.160 vs 0.033 ±0.025, P<0.05). Conclusion Danshao Granular Ⅲ, with its main action mechanisms of cooling blood and removing stasis , can effectively reduce urinary RBC count and urinary protein quantity and improve the symptoms of HSPN in rats .

Objective To identify the relationship between viral factors and disease progression in patients with acute hepatitis B virus (HBV) infection. Methods Ninety-seven adult patients with acute HBV infection in Shanghai Changhai Hospital were enrolled in this study and followed up for 24 weeks. Epidemiological, biochemical and virological parameters of all patients were collected. HBV S region from sera of 54 patients with acute HBV infection were genotyped using direct nucleotide sequencing. Differences of means between groups were compared by t-test, and frequency between groups was compared by X test. Results The clinical manifestations of all patients were mild and the 83 patients spontaneously developed HBeAg and HBsAg seroconversion. However, 14 patients had a tendency of chronicity, with HBV DNA level higher than patients without chronicity tendency [(6. 17 ±1. 04) 1g copy/mL vs (3. 86±1. 85)1g copy/mL;t = 5. 95, P<0. 01]. Among the 14 patients, 6 obtained HBsAg seroconversion after antiviral therapy and the other 8 developed to be sustained HBV carrier who had not received antiviral therapy. The main genotypes of acute HBV infection were genotypes B and C. There were no statistically significant differences of epidemiological factors and biochemical results between patients with the two genotypes of HBV infection. High viral load at baseline was the risk factor of chronicity tendency. Conclusions The main genotypes of acute HBVinfection in Changhai Hospital in the year from 2003 to 2007 are genotypes B and C. There is no significant relationship between genotype and clinical outcome. While high viral load at baseline is significantly associated with chronicity tendency. Proper antiviral therapy can decrease sustained HBV infection rate.

Objective To investigate the distribution of genotypes in chronic HBV infection (CHB) and acute HBV infection (AHB) patients in Shanghai. Methods Sixty-two patients with AHB and 73 patients with CHB admitted to ('hanghai Hospital of Shanghai between 2003 and 2007 were studied. Viral genotypes of all the patients were determined by direct gene sequencing.Meanwhile, epidemiological, clinical and biochemical parameters of all patients were collected. Mean values of different groups were compared by t test while frequency was compared by chi square test. Results The major prevalent genotypes in both AHB and CHB patients were genotype B and C (48.4% vs 51.6% in AHB patients and 26.0% vs 74.0% in CHB patients). The proportion of genotype B was higher in AHB patients compared to CHB patients (P= 0.02). Epidemiological factors and clinical outcomes were not statistically different among patients with different viral genotypes. The proportion of genotype C was much higher in CHB patients compared to AHB patients (P=0.006). The main transmission route of AHB was heterosexual interaction which was 18 out of 62 (29.0%), but in CHB patients, it was prenatal transmission which was 38 out of 73 (52.1%). Conclusions In shanghai, the main HBV genotypes in both AHB and CHB patients are genotype B and C. The proportion of genotype B is relatively high in AHB patients while proportion of genotype C is more common in CHB patients. There is no significant relationship between genotypes and the clinical outcomes of AI-IB patients.
