Background Hypertension,ischemia and hypoxia induce the increase of glutamate level in eye tissue and furthermore produce excitatory damage and apoptosis of retinal ganglion cells(RGCs).At present,the study on the protection of traditional Chinese medicine on glutamate-induced retinal excitatory damage is lack.objective Present study was to explore the protective effects of Huoxue huayu decoction,a Chinese herbal recipe,on RGCs in acute ocular hypertension model. Methods Fony-five healthy clean Wistar rats were divided into three groups randomly.The acute ocular hypertension models were established in 40 Wistar rats by injecting the normal saline solution into the anterior chamber to elevate the intraocular pressure for 60 minutes.Huoxue huayu decoction of 4 ml was administered intragastrically once per day in 20 model rats.Other matched 5 normal Wistar rats served as normal control group.The rats were sacrificed on 1,3,7 and 14 days after modeling and the retinas were isolated for the histopathologieal and uhrastructure examination.Expression of glutamate transporter in the retina of acute ocular hypertension and normal rat retina were detected using quantitative real-time polymerase chain reaction.The utilization of animals followed the Association for Research in vision and Ophthalmology. Results After acute ocular hypertension.the retina thickness attenuated and the numbers of RGCs decreased under the light microscope in 1,3,7 and 14 days after modeling in comparison with normal control rats.The degradation of the organelle and edema as well as changes of cell nuclei were seen in model rats under the transmission electron microscopy.The expression of glutamate transporter mRNA in model group and glutamate transporter group was rapidly elevated in the first day (P<0.05),descended at the third days(P<0.01)and returned to the normal level 7 days later(P>0.05).Conclusion Huoxue huayu decoction can protect the retina against RGCs damage in the acute ocular hypertension by elevating the expression of glutamate transporters in retina.

Fosfomycin (FOM) is an antibiotic with a small relative molecular weight (138.1) and a long half-life, and has a unique chemical structure and antibacterial mechanisms. It exerts a bactericidal activity by inhibiting the early synthesis of bacterial cell walls. It is also a broad-spectrum antibiotic with a good drug tolerance and compliance and a low pressure to bacterial resistance, but no cross-resistance with other antibiotics. Recent studies show the effectiveness of FOM in the treatment of acute uncomplicated urinary tract infections and urogenital tract infections as well, such as prostatitis and epididymitis. This review focuses on the clinical application of FOM in the treatment of infectious diseases of the urogenital tract.

This study is to analyze and identify the water soluble components of water buffalo horn (Bubali Cornu, WBH), and also establish a method for investigating these components. Shotgun proteomic analysis identified proteins in WBH aqueous extraction: keratin, collagen, desmoglein, etc. Ultrafiltration and LC-MS/MS were used to separate and identify the peptides in WBH aqueous extract, as a result, identified peptides were mainly derived from nonspecific degradation products of keratin and collagen, which including C-terminal peptides and non C-terminal peptides. Hypoxanthine, uridine, guanosine, and adenosine were identified by comparing with the standards. The strategy in present study could be used in analyzing water soluble components of animal horn derived TCM. It provides a reference for investigation of the material basis of animal horn derived TCM.

OBJECTIVETo investigate the mothod and therapeutic efficacy of total hip anthroplasties (THA) for osteoarthritis secondary to Crowe type IV developmental dysplasia of hip in adults.

METHODSFrom May 2006 to December 2013, THA was performed on 15 adult patients (17 hips) with Growe type IV acetabular dysplasia, including 13 females and 2 males, with a mean age of 30.9 years old (22 to 58 years old) and an average preoperative Harris score of (34.0 ± 6.5) points. Traction of the affected limb was not performed before surgery. After extensive release and lengthening of soft tissues, sub-trochanteric osteotomy of the femur was performed, hip joint center was rebuilt and the abduction function was restored.

RESULTSThe patients were followed up with a mean period of 33 months (ranged from 6 months to 5 years). The postoperative Harris score was 85.0 ± 7.3,higher than the preoperative score. The extended length of limb ranged from 1.6 to 5.4 cm, with a mean of (3.42 ± 0.65) cm. The shortening and malformation of the affected limb were corrected in the most patients,with the difference in length of the two legs less than 1.5 cm. After surgery, 1 patient experienced partial sciatic nerve injury, which was largely recovered after 3 months of conservative treatment. One patient experienced complete sciatic nerve injury, which was partially recovered after 6 months of conservative treatment; a foot-drop varus deformity was formed in the distal end of the affected limb, which was improved after tendon transposition and transplantation. Joint pain was relieved, and the joint function was restored significantly. Over the follow-up period, no severe complications such as dislocation, infection, prosthesis loosening, or subsiding occurred.

CONCLUSIONSatisfactory efficacy can be achieved for adult Growe type IV acetabular dysplasia associated with osteoarthritis by THA, with proper soft tissue release and lengthening, sub-trochanteric osteotomy of femur, joint functional restoration, appropriate choice of prosthesis, and careful protection of nerves and vessels.

Objective To explore the methods and clinical value of transrectal ultrasound (TRUS) in detecting rectal gastrointestinal stromal tumor(GIST) with head scanning probe.Methods A total of 12 patients had the ultrasonic examination through the rectum with the head scanning probe.Preoperative ultrasonic findings were compared with the pathological results.Results Of the 12 patients,the patients were divided into three groups,including 3 cases with low-degree severity,6 cases with moderate-degree severity and 6 cases with high-degree severity.The lymph node metastasis was not found near intestines.Rectal GIST appeared as a hypoechoic mass with clear limit、regular form and expanded growth under TRUS.The CDFI showed abundant flow in the tumor and TRUS had an overall accuracy rate of 75.0%(9/12)in the diagnosis of rectal GIST.The accuracy of TRUS in the staging diagnosis of rectal GIST was 83.3%(10/12).Conclusion The TRUS with the head scanning probe is of great value for pre-operative diagnosis and staging of rectal GIST.Rectal water window and felicitous check-up technique can enhance the accuracy of TRUS.

The incompatibility of traditional Chinese medicines is related to the clinical medication safety, so has attracted wide attentions from the public. With the deepening of studies on the incompatibility of traditional Chinese medicines represented by 18 incompatible herbs, the incompatibility of theory traditional Chinese medicines has raised to new heights. From the origin of incompatibility theory of traditional Chinese medicines, relationship of herbs, harms of incompatible herbs and principle of prevention to toxic effects of specific incompatible medicines, the innovation and development of the traditional Chinese medicine incompatibility theory was explored. Structurally, the incompatibility of traditional Chinese medicines refers to the opposition of two herbs based on seven emotions and clinical experience. The combination of incompatible herbs may lead to human harms, especially latent harm and inefficacy of intervention medicines. The avoidance of the combination of incompatible herbs and the consideration of both symptoms and drug efficacy are the basic method to prevent adverse reactions. The recent studies have revealed five characteristics of incompatible herbs. Toxicity potentiation, toxication, efficacy reduction and inefficacy are the four manifestations of the incompatible relations. The material changes can reflect the effects of toxicity potentiation and toxication of opposite herbs. The accumulation of toxicity and metabolic changes are the basis for latent harms. The antagonistic effect of main efficacies and the coexistence of positive and negative effects are the distinctive part of the incompatibility. The connotation of incompatible herbs plays an important role in the innovation of the traditional Chinese medicine incompatibility theory.

OBJECTIVETo study the mechanism of spontaneous rupture of hepatocellular carcinoma (HCC).

METHODSThe specimens of 30 patients with ruptured HCC and 30 patients with non-ruptured HCC were collected. Immunofluorescence, immunohistochemical and flow cytometry techniques were used to detect the phagocytosis of macrophages and the deposition of immune complex (IC) on vascular wall.

RESULTSIn this study, the poor function of macrophage phagocytosis was found in patients with ruptured HCC, which could results in the cumulating of IC and deposition on vascular wall. The IC, which composed of hepatitis B virus e1 antigen (HBeAg/1), complement C1q and immunoglobulins, was found deposited in the elastic membrane of arteries. Likely as a result of IC deposition, vascular injury occurs mainly in the small arteries where the deposition of IC was present. As the small arteries were the blood vessels with predominant injury, they would likely to be the ones to split and cause hemorrhage and rupture of HCC during vascular load increase.

CONCLUSIONSWe would conclude that the poor function of macrophage phagocytosis, which lead to the IC deposition and vascular injury may be the factors involved in the pathogenesis of ruptured HCC.
