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.

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.

Objective To apply the urethral pressure profile(UPP)in patients with benign prostates hypertrophy(BPH).Methods 71 patients with BPH accepted the test of UPP.The UPP parameters were compared statistically with the ultrasonography finding.Results The maximum urethral pressure,maximum urethral closure pressure and prostatic urethral length in BPH were higher than normal(P<0.01).Conclusion The test of urethral pressure profile(UPP)is helpful for identifying the site of obstruction and degrees in BPH patients,although there are some limits.

Objective To discuss the video-urodynamic characteristics and management in infra-sacral cord injured patients. Methods The video-urodynamic finding and managements in 169 patients was reviewed. They were followed up for 2 years. Results Detrusor areflexia was found in 76.33% (129/169) patients, among them there were 27.22% (46/169) patients appeared hyper-compliance, and 7.10% (12/169) patients appeared reflux. The video-urodynamic characteristics showed over activity and low-compliance in 12.43% (21/169) patients, including reflux in 5 cases. Different management was chosen according to the video-urodynamic examination. No special complication was observed after 2 years follow-up. Conclusion The majority patients with infra-sacral cord injury appeared detrusor areflexia and hyper-compliance. Special management according to the video-urodynamic characteristics is important for protecting upper urinary tract and preventing urinary system infection.

Abstract:Alcoholic liver disease (ALD) is one of the most common liver diseases in the world. Long-term alcoholism causes a series of pathological changes in the liver, which eventually leads to the occurrence of liver diseases with an increasing incidence. At present, significant progress has been made in the pathogenesis and pathological development of alcoholic liver disease, but the relevant mechanism of ALD has not been thoroughly studied. It is necessary to improve the existing animal model or establish a new, more comprehensive animal ALD model to simulate human ALD. Experimental animal models of ALD, especially rodents, are often used to simulate human ALD, and the ideal rodent ALD model can effectively simulate all aspects of alcohol in human liver. But so far, the commonly used animal models all have certain defects, and there is no complete animal model that can simulate human ALD. This paper reviewed the pathogenesis of ALD, related methods and influencing factors of ALD model, and provided a theoretical basis for relevant researchers to establish the ALD rodent model. 

OBJECTIVETo observe the effect of detoxifying and blood circulation activating Chinese herb extraction of polygonum cuspidatum and hawthorn on carotid intima-media thickness (IMT), plaque integral and plaque stability related serum indexes of patients with carotid atherosclerosis.

METHODSixty and four cases of carotid artery atherosclerosis patients were assigned randomly to 2 groups: detoxifying and blood circulation activating treatment group (treatment group, 32 cases) and control group (32 cases). Patients in treatment group were treated with capsules of extraction of polygonum cuspidatum and hawthorn, 1 pill po, bid (dosage of administration: polygonum cuspidatum extraction 5.33 mg x kg(-1) x d(-1), hawthorn extraction 5.0 mg x kg(-1) x d(-1)); patients in control group were treated with lovastatin 20 mg po, qd (dosage of administration: 0.33 mg x kg(-1) x d(-1)). The course of treatment was six months. To observe changes of IMT, plaque integral, and detect the level of plaque stability related serum indexes such as Hs-CRP, MMP-1 and TIMP-1.

RESULTAfter 6 months of treatment, in control group one patient quit the clinical trial because of liver dysfunction and one patient was rejected because of having not followed the therapeutic regimen. 32 cases in treatment group and 30 cases in control group were analyzed. The results showed that IMT and plaque integral of treatment group decreased significantly after the treatment (P < 0.05, P < 0.01), and there was no significant difference compared with control grope. Serum Hs-CRP, MMP-1 and MMP-1/TIMP-1 decreased after the treatment (P < 0.05, P < 0.01), and the treatment group was superior to control group in decreasing serum Hs-CRP (P < 0.05).

CONCLUSIONDetoxifying and blood circulation activating Chinese herb extraction of polygonum cuspidatum and hawthorn has good effect of anti-atherosclerosis and promoting plaque stability. Its mechanism might be related with anti-inflammation and inhibiting degradation of extracellular matrix, and deserves further studies.
