Objective To observe the effects of Compound Uncaria Hypotensive Tablets on expressions of MCP-1 and MMP-9 of vascular remodeling in spontaneously hypertensive rats (SHR); To discuss it possible mechanism of action. Methods Totally 24 12-week old male SHR were randomly divided into SHR model group, Compound Uncaria Hypotensive Tablets group, and positive medicine group, with 8 rats in each group. Another 8 WKY rats were set as normal control group. Medication groups were given relevant medicine for gavage for successive 6 weeks. Noninvasive tail cuff method was used to observe blood pressure; morphological changes in thoracic aorta and renal artery were observed by HE staining; immunohistochemistry was used to detect the protein expressions of MCP-1 and MMP-9 in thoracic aortic wall. Results Protein expressions of MCP-1 and MMP-9 in thoracic aortic wall of SHR model group were significantly higher than those of normal control group (P<0.01); Compared with the SHR model group, protein expressions of MCP-1 and MMP-9 in thoracic aortic wall decreased significantly in the medication groups (P<0.05, P<0.01); Compared the Compound Uncaria Hypotensive Tablets group and positive medicine group, there was no obvious difference in protein expressions of MCP-1 and MMP-9 in thoracic aortic wall. Conclusion Compound Uncaria Hypotensive Tablets can reduce the blood pressure of SHR, reduce inflammation reaction, and regulate vascular remodeling, which mechanism may be related to down-regulation of expressions of MCP-1 and MMP-9 in SHR aortic endothelial cells.

OBJECTIVETo study the clinical features of juvenile primary fibromyalgia syndrome (FMS) and to evaluate outcome after treatment.
METHODSSix patients with juvenile primary FMS were registered in department of rheumatology and their clinical data were assessed, including degree of pain (visual analog scale, VAS), fatigue, depression, anxiety, sleep disturbances, arthrodynia, subjective joint swelling, abdominal pain, irritable bowel symptoms, urinary urgency, dysmenorrhea, morning stiffness, paresthesias, illness changes with weather, feeling worse with exercise, laboratory examination and outcome of treatment.
RESULTSAbdominal pain was the first symptom in 5 of the cases with juvenile primary FMS, diffuse aching and left knee pain were the first symptoms in one patient. All the 6 patients were misdiagnosed prior to their rheumatological evaluation. Diffuse aching, fatigue, sleep disturbances, illness changes with weather and feeling worse with exercise existed in all the 6 patients (100%), the mean pain score was 8.8 and the mean initial tender points (TP) count was 13.7. Arthrodynia, subjective joint swelling, abdominal pain, irritable bowel symptoms and urinary urgency existed in 5 of the 6 patients (83%). Dysmenorrhea existed in 4 (67%), depression in 3 (50%), morning stiffness in 2 (33%), paresthesias in 2 (33%) and anxiety in 2 (33%), respectively. The results of laboratory examination were normal and the outcomes of treatment were good.
CONCLUSIONJuvenile primary FMS may not be a rare disease and the clinicians should pay more attention to it for avoiding misdiagnosis.

Passiflora was a nourishing and healthy fruit grown in tropical and subtropical regions. Passiflora has been widely used to alleviate various diseases in the folk in tropical nations, especially as a treatment for insomnia and anxiety in Europe. The title plant had been used as antalgesic and downer from the beginning of the 20th century up to now. The demands of Passiflora and its extract have been increasing. Therefore, comprehensive utilization of this plant is necessary. This paper reviewed the progress in the study on the chemical composition, nutrient value, and pharmacological effect of the genus of Passiflora.

Objective To improve the safety of surgery,the application of indocyanine green fluorescein(ICG)angiography in intracranial aneurysm surgery was investigated.Methods Fifty cases of intracranial aneurysms were retrospectively analyzed.All the patients were received ICG angiography before and after intracranial aneurysm clipping.The efficiency of the surgery was evalu-ated with CT angiography(CTA)and(or)digital subtraction angiography(DSA).The postoperative follow-up was conducted using Glasow outcomes score(GOS).Results Of the 50 patients,3 cases of aneurysmal neck remnant,one case of parent arteries steno-sis,one case of nearby branch stenosis and two cases of “false-negative”were observed after ICG angiography.The clips were adjus-ted until the satisfactory blood flew was restored.Postoperative CTA and(or)DSA confirmed the results of intraoperative ICG an-giography.Of the 40 patients underwent follow-up,GOS score was 5 in 30 cases,4 in 7 case,3 in 2 case and 2 in 1 case.Conclusion ICG angiography is a useful way to assess the clipping of aneurysms,blood flew of parent arteries and nearby branches during the aneurysm surgery.It could raise the safety of surgery and further improve the clinical outcomes of intracranial aneurysms.

Objective To determine the association of one single nucleotide polymorphism loci G 398C in PRM2 with male in‐fertility in Chinese Han population .Methods A total of 386 infertile men were recruited as the observation group and 255 fertile men were recruited as the control group .Routine semen analysis as well as sperm functional parameters such as DNA integrity and nucleoprotein maturity rates were analyzed .Direct sequencing of G398C in PRM2 gene of infertile and fertile men was also conduc‐ted to evaluate the association of G398C SNP loci with male infertility .Results Statistical analysis showed that the frequencies of CC genotype of PRM2 G398C was significantly different between the infertile (11 .92% ) and fertile men (6 .67% ) and it was asso‐ciated with increased risk of male infertility (OR= 2 .002 ,95% CI= 1 .097 -3 .653 ,P< 0 .05) .Moreover ,it was discovered that sperm DNA integrity as well as nucleoprotein maturity rate of CC genotype were dramatically decreased compared with other geno ‐types (P<0 .05) ,which would probably lead to infertility .Conclusion Our results gave the first evidence that PRM 2 G398C poly‐morphism was associated with male infertility in Chinese Han population .

Objective To investigate the neuroprotective effect of cattle encephalon glycoside and ignotin injection on the rat model of traumatic brain injury (TBI).Methods Three hundred and six SD rats were randomly divided into sham group,TBI group,high dose group,middle dose group and low dose group according to the random number table.Rats received 1.8,0.6 and 0.2 ml/kg of cattle encephalon glycoside and ignotin injection for 28 days in high,middle and low dose groups,respectively.TBI was induced by the modified Feeney' s weight-drop method.Rat mortality,neurological function score and learning and memory ability were recorded.Brain morphological changes were evaluated with 7.0 T small animal nuclear magnetic resonance and HE staining.Evans blue was applied to assess blood brain barrier (BBB) permeability and hydrocephalus was evaluated by the brain water content.Results Mortality in high dose group decreased significantly compared to that in TBI group (22.40% vs.28.14%,P < 0.05).Defects in neurological function and learning and memory induced by TBI were significantly mitigated in middle and high dose groups (P < 0.05).Pathological damage and contralateral hippocampal atrophy in middle and high dose groups were reduced significantly compared to TBI group (P < 0.05).Hippocampus neuroapoptosis in middle and high dose groups was significantly improved compared to TBI group (P < 0.05).BBB damage was less severe in middle and high dose groups than in TBI group (P < 0.05).The treatment was preventive against secondary hydrocephalus.Conclusion Middle or high dose cattle encephalon glycoside and ignotin injection over a 28-day period has significant neuroprotective effect on the TBI rats.
