? AIM: To compare the effects on the retina inner segment and retinal pigment epithelium ( RPE ) of intravitreally injecting bevacizumab, ranibizumab and aflibercept into monkey eyes.? METHODS: Fourteen healthy cynomolgus monkeys (Macaca fascicularis, aged 3-8y,10 males,4 females) were raised at the Covance Laboratories under standard conditions. The 14 monkeys were grouped into 4 groups. Three of the groups with 4 monkeys each were injected intravitreally with one of the drugs, either bevacizumab, ranibizumab or aflibercept, while the 4th group with 2 monkeys served as a negative control. On 1d and 7d of injection, 2 monkeys from each drug treatment group were sacrificed under general anaesthesia and the 4 eyes were enucleated. All the enucleated eyes were fixed in formalin, embedded in paraffin wax, cut into 4. 0 μm sections and deparaffinized according to standard procedures. Image-Pro Plus was used for all the photos to measure the content of vascular endothelial growth factor ( VEGF) in the inner segment and RPE. The ANOVA test from JMP10. 0 statistical program was used to evaluate the results.?RESULTS:Retinal sections were checked for their anti-VEGF immune reactivity. The untreated control samples had the highest level of VEGF in the RPE and inner segment. All of these three drugs can reduce the level of VEGF in the RPE and inner segment, but Avastin seems to be more effective than Eylea in this regard. Lucentis treatment at 1d seems to be more effective than Eylea at VEGF 1d. But at 7d, both Lucentis and Eylea have the same effect on reducing VEGF expression level in the RPE and inner segment.?CONCLUSION: All of these three drugs can reduce the level of VEGF in the RPE and inner segment.

Objective To explore the effect of Qingretonglin pill combined with levofloxacin tablet on urinary tract infection after spinal cord injury. Methods 55 spinal cord injury patients with urinary tract infection were divided into control group (n=27) and observation group (n=28). Levofloxacin tablets were orally administered in both groups, 500 mg everyday, 14 days. The Qingretonglin pill was also orally administered in the observation group, 1.6 g, 3 times every day, 14 days. The improvement time of frequent micturition, urgent urination and odynuria, and urinary leukocyte number, urinary bacterial quantitative culture changes and the side effect before and after treatment were observed. Results The effective rate was higher in the observation group (89.3%) than in the control group (63%) (P<0.05). The improvement time of frequent micturition, urgent urination and odynuria was shorter in the observation group than in the control group (P< 0.05). The number of urinary leukocyte and urinary bacterial significantly decreased after treatment (P<0.001), and was less in the observation group than in the control group (P<0.05). The rate of side effect was low in both groups, and there was no significant difference (P> 0.05). Conclusion Qingretonglin pill can release the clinical symptoms of urinary tract infection after spinal cord injury, and improve the clearance rate of bacteria.

Diabetes is seriously hazards to human health and its pathogeneses are not clear. Recent studies show that the imbalance of intestinal flora and the development of diabetes are closely related. Appropriate bacteria can improve blood sugar disorder. Treating diabetes from the theory of Pi-Wei is effective. Regulating intestinal flora has become a new pathway for treating diabetes from the theory of Pi-Wei. On the basis of intestinal flora, authors discussed the treatment of diabetes from Pi and Wei.

J6-1 cell line is the first leukemic cell line established in China. It is a multi-clone cell line infected with both EBV and HHV-6. Many cytokines, receptors and other genes were cloned from J6-1 cell line since its establishment 30 years ago. Valuable information on leukemic characteristics and functions were obtained from the studies on this cell line, which could be categorized into several research subjects. These achievements implied the unique research value of multi-clone cell lines. This comment focuses attention on research advance of the J6-1 leukemic cell line in 30 years, including heterogeneity and multi-cloning of J6-1 cells, survival mechanism of J6-1 cell populations, abnormal intercellalar communication of J6-1 cells with its significance and inspiration from J6-1 cell line.

Objective To investigate the impact of detrusor hyperactivity with impaired contractile function(DHIC)on voiding function in benign prostatic hyperplasia(BPH).Methods68 patients with BPH accepted the test of urodynamics.The urodynamic parameters between DHIC group and no DHIC group were compared statistically.ResultsThe residual urine in DHIC group was larger and the detrusor pressure at Qmax,the bladder volume were smaller than that in no DHIC group(P<0.01).ConclusionDHIC worsens the voiding function of the patients with BPH,and the test of urodynamic is helpful to diagnose and to treat it.

ObjectiveTo recognize the features of genitourinary dysfunction in multiple system atrophy (MSA) and the importance of videourodynamics.Methods5 cases of MSA were reviewed.ResultsGenitourinary dysfunction in MSA included voiding problem, nocturnal urinary frequency, urgency, impotence and so on. The characteristic appearance of videourodynamics was that postvoiding volume more than 100 ml, detrusor-external sphincter dyssynergia (DESD) and open bladder neck at the start of bladder filling. The abnormal sphincter electromyography comprised of abnormal spontaneous activity, motor unit potentials (MUPs) more than 13 ms, polyphasic potentials more than 60%. MRI showed brain atrophy and the "hot cross bun" signal in the pontocerebellar degeneration.ConclusionMSA is a disorder characterized by progressive neuronal atrophy at certain sites of the central nervous system that control the urogenital function. MSA-related urological symptoms are analogous with symptoms of bladder outlet obstruction. It is necessary to take some reasonable investigations for avoiding misdiagnosis and unnecessary surgery.
