Objective: To assess the efficacy of Tongxinluo for diabetic kidney disease. Methods: we conducted a systematic review of randomized controlled trials (RCTs) in which Tongxinluo was used to treat diabetic kidney disease. And we screened relevant studies according to predefined inclusion and exclusion criteria, evaluated the quality of the included studies, and performed meta-analyses by using The Cochrane Collaboration's Revman 5.0 software. Results A total of 11 RCTs were enrolled in the review. The results of meta-analysis showed that Tongxinluo was better on attenuating 24 hour urinary protein,BUN and UAER; Tongxinluo was not superior to no treatment on the improvement of Scr and Ccr; Tongxinluo was better than no treatment on the Regulation of blood lipids, such as TC, TG, LDL-C. However, Tongxinluo might have similar effects on the improvement of HDL-C; Tongxinluo was better than no treatment on the improvement of FBG, but xuezhikang was not superior to no treatment on the improvement of P2BG and HbA1c. Tongxinluo was better than no treatment in decreasing plasma endothelin (ET). No significant adverse effects or Allergic reactions were reported. Conclusion: The evidence currently available shows that Tongxinluo has some effect and is relatively safe in treating patients with diabetic kidney disease.Due to a high risk of selection bias and detection bias in the included studies, the evidence is insufficient to determine the effect of Tongxinluo. Further large-scale trials are required to define the role of xuezhikang in the treatment of DKD. © 2010 Editorial Board of Chin J Evid-based Med. Source

It has been reported that Nur77 over-expresses in arteriosclerotic lesions and has both pro- and anti-proliferative effects on vascular smooth muscle cells (VSMCs). We investigated the physiological function of Nur77 on proliferation in VSMCs and the effects of atorvastatin on the expression of Nur77. Platelet-derived growth factor (PDGF), a key growth factor mediating VSMC proliferation in atherogenesis and post-angioplasty restenosis, was employed to induce the transcriptional regulation of Nur77 expression in VSMCs and rat carotid artery post-angioplasty restenosis models were used to investigate the effect of atorvastatin on the expression of Nur77 by immunohistochemistry, RT-PCR, and western blot methods. In cell models, we found that PDGF-B induced Nur77 mRNA expression and protein expression through ERK-MAPK-dependent signaling pathways, and atorvastatin attenuated the expression of Nur77 induced by PDGF-B. In the rat model, our data showed Nur77 was up-regulated in neointima, but down-regulated by atorvastatin. Our results indicate that Nur77 promotes VSMC proliferation, and down-regulation of Nur77 by atorvastatin suggests a novel therapy strategy for atherogenesis based on suppression of VSMC proliferation. © 2010 Springer Science+Business Media, LLC.

It has been reported that exposure to infrasound causes cardiac dysfunction. Allowing for the key role of apoptosis in the pathogenesis of cardiovascular diseases, the objective of this study was to investigate the apoptotic effects of infrasound. Cardiac myocytes cultured from neonatal rats were exposed to infrasound of 5 Hz at 130 dB. The apoptosis was determined by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling. Also, the expression levels of a series of apoptosis-related proteins were detected. As a result, infrasound induced apoptosis of cultured rat cardiac myocytes in a time-dependant manner. The expression of proapoptotic proteins such as Bax, caspase-3, caspase-8, caspase-9, and FAS was significantly up-regulated, with concomitant down-regulated expression of antiapoptotic proteins such as Bcl-x, and the inhibitory apoptosis proteins family proteins including XIAP, cIAP-1, and cIAP-2. The expression of poly (ADP-ribose) polymerase and β-catenin, which are the substrate proteins of caspase-3, was significantly decreased. In conclusion, infrasound is an apoptotic inducer of cardiac myocytes. © 2011 Springer Science+Business Media, LLC. Source

Background Pituitary adenomas are common intracranial tumors, with a rising incidence in China. Excision is a mainstay therapy for this disease, and is often carried out via transfrontal, transsphenoidal or transpterional approaches. However, few studies have systematically addressed the regional anatomy involved in these microsurgical procedures. The present study attempted to establish some key anatomic measurements relevant to pituitary adenoma resection based on cadaver and computer tomography (CT) image studies. Methods Head specimens from 30 randomly selected formalin-fixed adult cadavers were used for anatomical analysis. Measurements were made on the base of the skull following removal of brain structures above the pituitary gland, and on the mid-sagittal plane of the cranium. Parameters were designed by considering the 3 above-mentioned common microsurgical approaches, and obtained on each head using a sliding caliper. Multi-level CT images from 30 individuals were also used for distance measurements between landmark structures that are relevant to these surgeries. All data were subjected to statistical analysis using the SPSS 11.5 software. Results There was statistically significant difference (P <0.05) of distance measured on cadavers relative to CT images in 3 sets of measurements related to the transfrontal surgical approach, i.e., distances from the midpoint of superciliary arch superior border to the cranial entrance of internal carotid arteries (ICAs), the opposite side entrance of ICA and to the genu of ICA. While regional anatomical analyses were carried out according to the transpterional approach, statistically significant difference was also found in 3 sets of distance measurements between cadaver and CT image data, with regard to the distances between the pterion and some landmark structures around the pituitary. Conclusions The present study provides key anatomical and CT image measurements involving the 3 conventionally used surgical approaches for pituitary tumor resection. The data implicate that while CT scan results can provide valuable guidelines for operations, cautions and adjustments are needed during surgery for sufficient tumor excision and protection of key blood vessels and nerves in the vicinity of the pituitary gland and around the surgical pathway.

Study Objective: To describe our experience with endoscopic removal of cesarean scar pregnancy. Design: Retrospective study (Canadian Task Force classification II-3). Setting: Tertiary-care university hospital. Patients: Twenty-one patients with cesarean scar pregnancy. Interventions: All the patients underwent removal of pregnancy mass at hysteroscopy or combined with laparoscopy. Nine patients received a methotrexate injection before the operation, and 13 underwent uterine artery embolization before surgery. Measurements and Main Results: Clinical data, serum β-human chorionic gonadotropin concentration, findings of ultrasound or magnetic resonance imaging examinations, therapeutic options, operative time, operative blood loss, and duration of hospitalization time were recorded. The mean serum β-human chorionic gonadotropin concentration at diagnosis was 53350.4 IU/ L. Seventeen patients underwent hysteroscopy, which failed in 2, and the other 4 patients underwent hysteroscopy combined with laparoscopy. Mean operative time was 51.4 minutes, and mean blood loss was estimated at 48.1 mL. A gestational mass can be removed at hysteroscopy, with rapid recovery and a high success rate. If a cesarean scar pregnancy mass grows toward the bladder and abdominal cavity, hysteroscopy combined with laparoscopy is more appropriate. Preoperative uterine artery embolization can decrease blood loss substantially during the operation. No patients underwent hysterectomy. Conclusions: Endoscopy seems to be the optimal surgical management in patients with a cesarean scar pregnancy and who desire to preserve the uterus and fertility. However, further study is warranted. © 2010 AAGL. Source
