Secondary glaucoma is a kind of complications after vitrectomy, its etiologies are various and complex. Ineffective therapies might cause irreversible damage on optic nerves and visual field defect, even the loss in visual function. Nowadays, this project has been paid great attention by various researches both in China and abroad. Both the pathogens and therapies of secondary glaucoma after vitrectomy are analyzed as follows.

Objective:To observe the clinical efficacy of morpholine nidazole in the treatment of infection after radical resection of perianal abscess.Methods:Thirty patients diagnosed with perianal abscess were randomly divided into the observation group(given intravenous infusion of morpholine nidazole) and the control group(given intravenous infusion of ornidazole).Results:There was no significant difference in postoperative wound infection rate between the observation group and the control group ( P>0.05). There was significant difference in wound healing quality between the two groups on the 2 d and 7 d after the operation ( P<0.05). There was no significant difference in WBC and neutrophil counts between the two groups ( P>0.05), and the WBC and neutrophil counts in the two groups were significantly lower on the 7th day after the operation than before the treatment, and the observation group was significantly lower than the control group ( P<0.05). After treatment, there was no significant difference in the clearance rate of escherichia coli, klebsiella pneumoniae, bacteroides fragile and staphylococcus aureus in the observation group ( P>0.05), but there was significant difference in the overall bacterial clearance rate compared with the control group ( P<0.05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group ( P<0.05). Conclusions:The use of morpholinidazole in patients with perianal abscess is effective and safe.

?AlM: To investigate the clinical characteristics and influencing factors of chronic renal failure ( CRF) patients with dry eye, and to provide clinical reference.?METHODS:Sixty-one cases (122 eyes) of patients with CRF ( CRF group ) and 61 cases ( 122 eyes ) of healthy persons ( control group) were carried out on Schirmer ▏test ( S▏t ) , break-up time of tear film ( BUT ) , corneal fluorescein staining ( FL) , test results of two groups were compared and related factors of dry eye in CRF patients were analyzed.?RESULTS: The results of S▏t and BUT in CRF group were lower than that in the control group (P<0. 05). The proportion of tear secretion reduce in CRF group ( S▏t<10mm/5min) was 49. 2% ( 60/122 ), which was higher than that in the control group ( 10. 0%, 12/122 ), the difference was statistically significant ( X2 = 45. 39, P <0. 05). The percentage of instability of tear film in CRF group (BUT≤10s) was 75. 4% (92/122), which was significantly higher than that in the control group (27. 0%, 33/122) (X2=57. 1, P<0. 05). The positive rate of corneal FL was 37. 7% (46/122), which was higher than that of the control group (10. 7%, 13/122), there was a statistically significant difference (X2= 24. 34, P<0. 05).?CONCLUSlON:CRF patients with a decrease in tear film stability and tear secretion are susceptible population to dry eye, clinically should be paid attention to the treatment.

Biotechnology supremacy is a newly-advanced power theory. It is a superior dominance of military biotechnological application based on the microcosm of life structure within a certain period of time. The advancement of biotechnology supremacy and modern biotechnology has created the concept of bio-micro-frontier, which involves information and defense resources of all living ultra-micro-organisms with national and regional characteristics. Being feasible both in theory and practice, the implementation of bio-micro-frontier system is strategically important. This article explores the implementation of bio-micro-frontier in terms of strategy and tactics, which will add a unique dimension to future military transformation and active defense.

Objective To investigate the effects of glycyrrhizin on gene expression of transforming growth factor(TGF)-?signaling pathway of hepatic stellate cell(HSC)in mice by gene microarray tech- nique.Methods The HSCs were isolated from mice and cultured in vitro.Then the mice were divided into control group,TGF-?_1 group(5 ng/ml) or TGF-?_1(5 ng/ml)combined with glycyrrhizin(100?mol/L) group.The cells were collected after 10 hours to extract RNA.A cDNA microarray(GEArray~(TM) Q) targeting TGF-?/BMP signal transduction was used to screen the genes which showed significant changes in expression of TGF-?pathway of HSC by glycyrrhizin.Results The microarray analysis showed that 16 genes(16.7%),such as Smad2,Smad3,Smad7,CoL3A1,CoL1A2,and PAI-1,were upregulated by TGF-?_1 and then down-regulated by glycyrrhizin.Five genes(5.2%)(including BMP7,IGFbp3 and etc.)downregulated by TGF-?_1,were then up-regulated by glycyrrhizin.Finally,2 genes upregulated by TGF-?_1 were then up-regulated predominantly by glycyrrhizin in HSC(T?R2,betaglycan).Changes in some genes,such as Smad2 Smad3,Smad7,were further confirmed to be coincided with cDNA microarray by semi-quantitative RT-PCR.Conclusions The anti-fibrosis mechanisms of glycyrrhizin may be through to interference of TGF-?signaling pathway,decrease the synthesis and increase the degradation of collagen.

Angiotensin AngII, a linear small peptide,which is composed of eight amino acids, is the main effectors of renin-angiotensin systen (Renin-angiotensin system, ARS). AngII, a main biopolypeptide of the ARS, has important patho-physiologic in effects participating in cardiac hypertrophy, vascular cell proproliferation, inlfammation and tissue remodeling through G-protein-coupled receptors. In recent years, Ang II can promote tumor cell proliferation, tumor vessel formation and inhibit the differentiation of the tumor cells. hTis suggests that inhibit the production of AngII or block its effect is expected to become a new measure for the treatment of malignant tumors. hTis article reviews the advances in research on the relationship between AngII and its receptor and malignant tumor in recent years.

OBJECTIVETo study the protective effect of Ligustrazine Injection (LI) against cisplatin-induced ototoxicity and to explore its mechanism.

METHODSThirty healthy adult guinea pigs were randomly divided into three groups, 10 in each group, i.e., the normal control group, the cisplatin group, and the LI group. Guinea pigs in the normal control group were intraperitoneally injected with normal saline at 3 mL/kg for 7 consecutive days. Those in the cisplatin group were intraperitoneally injected with cisplatin at 3 mg/kg for 7 consecutive days. Those in the LI group were intraperitoneally injected with LI at 140 mg/kg for 7 days, but cisplatin (3 mg/kg) was intraperitoneally injected from the opposite side starting from the 4th day. Brainstem auditory evoked potential (BAEP) was performed in all animals before and after injection. All animals were sacrificed after the final testing under anesthesia and their cochleas collected. Half the cochleas of each group were collected for silver nitrate staining of cochlear basilar membrane stretched. The other half the cochleas of each group made into paraffin sections to observe the apoptosis of cochlea cells by TUNEL method and the expression levels of c-Jun detected by immunohistochemistry.

RESULTSThere was no statistical difference in the difference of BAEP threshold among the 3 groups before injection (P > 0.05), but the BAEP threshold increased in the cisplatin group and the LI group (P < 0.05). Besides, it was higher in the cisplatin group (P < 0.05). In the cisplatin group, most hair cells were missing, spiral ganglion cells obviously decreased, more TUNEL positive cells occurred, and the expression of c-Jun was stronger. But the aforesaid impairment in the LI group was obviously lessened (P < 0.05).

CONCLUSIONSLI showed certain antagonist effect on cisplatin-induced ototoxicity. Its mechanism might be associated with scavenging oxygen radicals of the cochlea tissue, improving the microcirculation, and fighting against apoptosis.
