Objective To evaluate the MR imaging features of chondrnblastoma. Methods MRI examinations of 20 patients with histological proven chondroblastoma were reviewed retrospectively. The MRI findings of chondroblastoma including the signal intensity, the shape, the growth patterns, and the surrounding bone marrow edema and the adjacent soft tissue edema, the periosteal reaction, the adjacent joint effusion were analyzed . Results All 20 cases demonstrated heterogeneous MR signal intensity on T1WI and T2WI images and showed Iobular margins. Sixteen cases demonstrated expansive growth patterns. Surrounding bone marrow edema was found in 18 cases and adjacent soft tissue edema in 14 cases. Periosteal reaction was identified in 6 cases. In 7 cases the tumor extended to adjacent soft tissue. Adjacent joint effusion was visible on MRI in 6 cases. Conclusion Heterogeneous signal intensity, lobular margins and expansive growth pattern, adjacent bone marrow and soft tissue edema were the common features of chondroblastoma on MRI.

Objective To investigate the effect of hydrogen sulfide (H2S) on brain injury and inflammatory response after cerebral ischemia/reperfusion in rats.Methods Forty-eight malc SD rats were randomly divided into four groups:sham operation group,ischemia/reperfusion (I/R) group,H2S-30 ppm group,and H2S-60 ppm group (n=12 in each group;1 ppm=1 mg/L).The middle cerebral artery occlusion method was used to induce a model of focal cerebral ischemia for 2 h and reperfusion for 24 h.After reperfusion for 24 h,the tape remove experiment was used to perform the nerve function evaluation.2,3,5-triphenyl-tetrazolium chloride staining method was used to measure the percentage of cerebral infarction volume.Enzyme-linked immunosorbent assay was used to measure the levels of interleukin (IL)-1 β and IL-6.Western blotting was used to detect the expression levels of inducible nitric oxide synthase (iNOS) and intercellular cell adhesion molecule-1 (ICAM-1),as well as the transposition activation of nuclear factor-κB (NF-κB).Results Inhalation of H2S could shorten the time required to remove the tape in a dose-dependent manner compared with the I/R group (I/R group vs.H2S 30 ppm group and H2S 60 ppm group:180 s vs.130 [113-157]s vs.110 [87-138] s;P< 0.05),reduced the cerebral infarct volume (48.8% ± 9.1% vs.23.3 % ± 5.1% vs.17.3 % ± 3.5 %;P < 0.05),downregulated the expression levels of IL-1β (39.53± 6.02 pg/mg protein vs.30.17± 3.46 pg/mg protein vs.22.69± 6.09 pg/mg protein;P <0.05) and IL-6 (54.65 ± 10.68 pg/mg protein vs.37.89 ±4.54 pg/mg protein vs.27.00 ±3.08 pg/mg protein;P < 0.05) in ischemic brain tissue,significantly decreased NF-κB nucleus/ cytoplasm ratio (4.40 ± 1.05 vs.3.07 ± 0.82 vs.2.30 ± 0.60;P < 0.05),inhibited expressions of iNOS (4.22 ±0.67 vs.3.14 ±0.90 vs.2.08 ±0.35;P <0.05),and ICAM-1 (5.45 ± 1.08 vs.3.45 ±0.67 vs.2.21 ±0.39;P <0.05).Conclusions Inhalation of exogenous H2S can reduce cerebral infarct volume after cerebral ischemia/reperfusion in a dose-dependent manner and improve neurological function.Its mechanism may be associated with the inhibition of NF-κB activation,down-regulation of its downstream iNOS and ICAM-1 expression levels,and decrease of IL-1β and IL-6 levels.

UNLABELLEDOBJECTIVE; To evaluate the efficacy and safety of Jiangtang Xiaozhi Capsule (JTXZC) in treating type 2 diabetes mellitus (T2DM) of qi-yin deficiency phlegm-stasis inter-obstruction syndrome (QYDPSIOS), and to observe its effect on inflammatory factors and fibrinolytic factors.
METHODSBy adopting a randomization grouping, parallel control, and prospective study, 73 T2DM patients of QYDPSIOS were assigned to two groups by random digit table, the Pioglitazone Tablet group (36 cases, as the control) and the JTXZC group (37 cases). All patients maintained their basic therapies and lifestyle as previous after recruitment. Patients in the JTXZC group took JTXZC, 4 pills each time, three times per day, while those in control group took Pioglitazone Tablet, 15 mg each time, once daily. The therapeutic course for all was 8 weeks. The body weight (BW), the height, body mass index (BMI), waist circumference (WC), hip circumference, waist-to-hip ratio (WHR), and scoring of Chinese medicine (TCM) symptoms were observed. Levels of fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h PBG), glycated hemoglobin (HbA1c), tumor necrosis factor alpha (TNF-alpha), nuclear factor kappaB (NF-kappaB), and plasminogen activator inhibitor 1 (PAL-1) were detected. The safety indices such as liver and renal functions and adverse reactions were also observed.
RESULTSCompared with before treatment, BW, BMI, HbA1c, and PBG were obviously lower after 8-week treatment than before treatment in the JTXZC group (P < 0.05). There was no statistical difference in post-treatment BW, BMI, HbA1c, or 2 h PBG between the two groups (P < 0.05). Compared with before treatment, levels of TNF-alpha and PAI-1 were lowered after 8 weeks of treatment in both groups (P < 0.01). The level of NF-kappaB was obviously lowered after 8 weeks of treatment in the control groups (P < 0.05), but it also decreased in the JTXZC group with no statistical difference. The scorings of CM symptoms were somewhat improved after treatment in the two groups (P < 0.01). Besides, better effects were obtained in the JTXZC group (P < 0.05). No severe adverse event occurred in either group during the whole therapeutic course.
CONCLUSIONSJTXZC showed similar therapeutic effect to pioglitazone. Both of them could effectively improve patients' clinical symptoms, the inflammation and fibrinolytic activities in different pathways, with no severe adverse reaction.

Background:The incidence of ulcerative colitis (UC)in developed countries is higher than that in developing countries,which may be related with westernized lifestyle,especially high animal protein and low complex carbohydrate diet. With the increased high fat and meat intake,synthesis and secretion of bile acid in liver is also increased,which may have an impact on the occurrence of UC. Aims:To investigate the expressions of farnesoid X receptor (FXR)and G protein-coupled bile acid receptor 5 (TGR5)in patients with UC. Methods:Thirty patients with active UC from January 2013 to June 2016 at the Affiliated Jiangning Hospital of Nanjing Medical University were enrolled,and 30 healthy subjects were served as controls. Expressions of FXR and TGR5 were determined by immunohistochemistry. Results:Compared with control group,expression of FXR was significantly decreased in UC patients (4. 63 ± 2. 07 vs. 6. 91 ± 2. 62,P =0. 00),however,no significant difference in expression of TGR5 was found between the two groups (6. 70 ± 2. 90 vs. 6. 11 ± 2. 44,P = 0. 40). Expression of FXR was significantly increased in right hemicolon colitis than in left hemicolon colitis (P < 0. 05). Conclusions:There is a significant decrease in FXR in active UC patients,indicating that FXR may have some role in the pathogenesis of UC,however,TGR5 may have no obvious effect in the pathogenesis of UC.

To obtain the genome sequence of human bocavirus 2 (HBoV2), different regions of HBoV2 genome were amplified through PCR in fecal specimens which had been identified as single-positive for HBoV2 in 2010. A genome sequence of HBoV2 (HBoV2-NC, 5444 bp) was obtained after sequence assembly. The phylogenetic analysis showed that HBoV2-NC had the closest evolutionary relationship with HBoV2 Lanzhou strain. The predication of inverted terminal repeats of HBoV2-NC by DINAMelt showed that inverted terminal repeats were contained in HBoV2-NC 5' terminal, which had the typical stem-loop structure in other parvoviruses. Finally, some flanking sequences of HBoV2-NC were amplified by linker-PCR.

OBJECTIVETo observe the clinical therapeutic effect of Nuzhen Yunyu Decoction (NYD, a Chinese recipe for nourishing blood and reinforcing Shen) and its influence on the hemodynamic parameters in ovarian and uterine arteries.
METHODSSixty-eight patients were randomly divided into two groups at the ratio of 2:1, 45 in the TCM group treated with Chinese medicine and 23 in the control group treated with clomiphene citrate. Menstrual cycle were taken as the indexes for clinical observation; basal body temperature, cervical mucus, vaginal exfoliative cells, serum hormones and B ultrasonic examination were taken as the indexes for ovulation and pregnancy assessment. The hemodynamic parameters of uterus and ovary were determined by using color Doppler ultrasonography, and the growth of follicles and ovulation, thickness of uterine endometrium were also monitored continuously.
RESULTSResults of 3 cycles treatment and 1 year follow-up study showed that the ovulation promoting rate, pregnancy rate and abortion rate in the two groups were similar, but the treated group showed better effects than that of control group, in such aspects as regulating menstruation, promoting growth and development of follicle, strengthening endometrium, improving blood supply and circulation of uterine and ovary (P < 0.05, P < 0.01).
CONCLUSIONNYD has the effects of ovulation promotion and holistic regulation of reproductive system.
