To observe the clinical effect of Yisui decoction plus western medicine in treating multiple system atrophy patients, totally 65 patients from China-Japan Friendship hospital during 2008-2012 with complete clinical data and received consecutive traditional Chinese medicine and western medicine treatment for more than 3 months were observed changes of traditional Chinese medicine symptom score, part 1 of unified multiple system atrophy rating scale, orthostatic hypotension before treatment and after 3 months treatment. After 3 months treatment, total effective rate of traditional Chinese medicine symptom was 70.8%. Compared with before treatment, score of part 1 of unified multiple system atrophy rating scale was obviously reduced after 3 month treatment (P < 0.001). Ex- cept swallow function without significant improvement, the remaining projects of unified multiple system atrophy rating scale were im- proved obviously (P < 0.05), of which the most obvious differences were orthostatic symptoms, falls and intestinal function (P < 0.001). Orthostatic hypotension after 1 month treatment and 3 month treatment was obviously better than before treatment (P < 0.001). There was no significant difference in orthostatic hypotension between 1 month treatment and 3 month treatment. The research results show that Yisui decoction plus western medicine has a certain effect on improving clinical symptoms of multiple system atrophy patients, especially has a significant effect on orthostatic hypotension, and can maintain a stable clinical effect in a certain period of time.

OBJECTIVETo observe the effect of Tangke Decoction (TD) on the expression of TGF-beta1/Smad4 of rats with early diabetes and to explore the effect and mechanism of TD against the renal injury induced by diabetes.

METHODSSD rats were randomly divided into the normal control group (n = 12), the model group (n = 10), the Chinese herbs prevented group (n =10), the Chinese herbs treated group (n = 10), and the Western medicine control group (n = 10). TD (18 mg/kg) was given by gastrogavage to rats in the Chinese herbs prevented group immediately after successful modeling for 12 weeks, once daily. At the 4th week of successful modeling, rats in the rest 4 groups were administered by gastrogavage. Equal volume of normal saline was given to rats in the model group and the normal control group. Benazepril suspension (1 mg/kg) was administered by gastrogavage to rats in the Western medicine control group for 8 weeks, once daily. TD (18 mg/kg) was given by gastrogavage to rats in the Chinese herbs treated group for 8 weeks, once daily. The body weight, kidney weight, index of kidney weight, fasting blood sugar, 24 h urinary albumin excretion rate were examined after experiment. The pathological changes of the renal tissue were observed by HE staining, Masson staining, and electron microscope. The expression of renal transforming growth factor-beta1, (TGF-beta1) and Smad4 were detected using immunohistochemical assay.

RESULTSCompared with the normal control group, the body weight of rats decreased significantly; the kidney weight, index of kidney weight, blood sugar, 24 h urinary protein excretion, the urinary albumin excretion rate,TGF-beta1 and Smad4 expression increased significantly in the model group (all P < 0.01). Compared with the model group, the aforesaid indices were improved in each treatment group with statistical difference (P < 0.05, P < 0.01). Compared with the Western medicine control group, the kidney weight, index of kidney weight, blood sugar, 24 h urinary protein excretion, and the urinary albumin excretion rate were obviously improved in the Chinese herbs prevented group (P < 0.01). The renal pathological changes were most obvious in the model group significantly, but they were improved in all treatment groups.

CONCLUSIONTD could obviously improve the symptoms of diabetes and down-regulate the expression of renal TGF-beta1 and Smad4 of early diabetic nephropathy rats, which suggested that TD had certain preventive effect on early diabetic nephropathy.

Objective To investigate the drug resistance genes of extended-spectrum beta- lactamase-producing bacteria in 49 strains.Methods Extended-spectrum ?-lactamase -producing strains were detected by the disc diffusion test.The techniques of polymerase chain reaction,sequence analysis, pulsed-field gel electrophoresis were used to analyze the genotype and homology of extended-spectrum ?- lactamase-producing strains.Results The incidence of ESBL-producing strains from E.coli,K pneumoniae,K oxytoca,was 20% in 2000,and 40% in 2003.Among the 49 ESBLs producers the most common genotype was CTX-M-14( n=33).The others were CTX-M-3,CTX-M-9,CTX-M-12,CTX-M-15, CTX-M-24 and SHVSa.Both two CTX-M subtypes,CTX-M-3 and CTX-M-14,were detected in one strain. However,4 ESBL-producing strains confirmed by phenotype remained untyped.The results showed that the ESBLs producers were not closely related,except for two strains of E.coli and two strains of K.pneumoniae which were homgenic respectively.Concolusions The incidence of ESBL-producing strains increases with years.The most common genotype of ESBLs is CTX-M.There is no evidence for epidemiologic spread of ESBL-producers by pulsed-field gel electrophoresis.

AIM: To analyze clinical data of hospitalized patients with age - related cataract treated through clinical pathway in our hospital, and to investigate the effectiveness of clinical pathway in standardizing medical behavior, advancing work efficiency, and improving quality of hospital management.
METHODS:Data of patients with age-related cataract, who were treated with phacoemulsification combined with intraocular lens implantation in Xi'an North Hospital, were retrospectively analyzed. In clinical pathway group, 220 patients underwent cataract surgery from October 2012 to May 2013 in accordance with clinical pathway. For control group, 213 patients with cataract receiving surgery from October 2010 to June 2011, comply with conventional process. Effect of cataract surgery, average length of hospitalization, average cost of hospitalization, and degree of satisfaction of patients were comprehensive investigated.
RESULTS: In 220 patients of clinical pathway group, 209 ( 95. 0%) got improved vision, the days of hospitalization was 4. 5 ± 1. 4d, and the average hospitalized consumption was 4 522. 3 ± 285. 1 Yuan. Whereas, in control group, visual acuity in 202 (94. 8%) out of 213 patients were improved, and the length and cost of hospitalization were 5. 1±1. 7d and 4 647. 7±271. 2 Yuan. The difference of the length and cost of hospitalization between these two groups were significant (P<0. 05). However, there was no statistically significance in curative effect and patients satisfaction compare (P>0. 05).
CONCLUSION: Practicing of age - related clinical pathway is helpful in standardizing medical heavier, optimizing clinical process, reducing health cost, improving quality of medical care, and providing evidence for hospital management innovation.

RNA has received more attention in the field of forensic medicine and the development of the new biological markers based on RNA shows great significance in the analysis of complex cases. circular RNA (circRNA) is a kind of non-coding RNA which is widely reported recently. Although the regulatory mechanisms of generation and expression are not fully clear, the existing research indicates that circRNA has important biological functions. CircRNA has a cell-type-specific expression with great stability and a high expression level, which makes it meaningful in forensic applications potentially. In this paper, the research progress, the generation and regulation of circRNA as well as its biological characteristics and functions are summarized, which will provide references for related studies and forensic applications.

OBJECTIVETo investigate the influence of seasons, blood types and semen parameters on the cryosurvival rate of frozen-thawed spermatozoa from sperm donors.

METHODSWe retrospectively analyzed the influence of seasons, blood types, abstinence period, semen volume, sperm morphology, and pre-freeze sperm motility and concentration on the cryosurvival rate of frozen-thawed sperm in 4 088 semen samples from Shaanxi Human Sperm Bank.

RESULTSThe cryosurvival rate of the post-thaw sperm was correlated negatively with the progressive motility of the pre-freeze sperm (r = -0.262, P < 0.01), but positively with pre-freeze sperm concentration (r = 0.247, P < 0.01), and it was significantly higher in the 6-day abstinence group ([70.2 +/- 5.4]%) than in the other abstinence groups (P < 0.01), so was it in the normal sperm morphology rate > 20% group ([71.4 +/- 5.1]%) than in the others (P < 0.01). The survival rate of the post-thaw sperm was not correlated with seasons, blood types, and semen volume (P > 0.05).

CONCLUSIONSperm motility, concentration and morphology and the abstinence period of sperm donors may be valuable predictors of the cryosurvival rate of post-thaw sperm, but no correlation was found between the survival rate and seasons, blood types and semen volume.

Based on data related to human brucellosis which was collected from the national notifiable infectious disease reporting system in the 6 provinces(Inner Mongolia,Shanxi,Heilongjiang,Shaanxi,Jilin and Liaoning)of north China from 2004 to 2007,at the county scale.Data would include age and gender standardized mortality ratios(SMRs)while ESDA was including histograms,box plots and box maps,global and local Moran' s I statistics,etc.The global Moran' s I values from 2004 to 2007 were 0.2581,0.4574,0.4457,0.4841,respectively and all with statistically significant differences.Most of local Moran' s I values were significant positive statistically.High-high counties were mainly in the northeast,most of which were pastoral areas,but the farming-pastoral areas and agricultural areas/town had an increasing trend over time.Low-low counties were mainly in the western and southern areas and most of which were agricultural areas/towns.Low-high counties appeared to be rare,mainly around the counties with high incidence,mainly belonged to agricultural areas/towns.The incidence rates of brucellosis in the six provinces of north China had a trend of increase from 2004 to 2007,namely spreading from east to west,from south to north,and from pastoral areas to farming-pastoral areas and agricultural areas/towns.ESDA could be used to develop effective measures for prevention and control of brucellosis.

In the treatment of hypertensive crisis, the novel Rho kinase inhibitor DL0805-2 can rapidly lower systematic blood pressure, reduce pulmonary artery pressure, and has a significant protective effect on lung injury. This experiment intends to evaluate the efficacy of DL0805-2 against pulmonary arterial hypertension (PAH) and preliminarily reveals its underlying mechanism. Animal welfare and experimental procedures are in accordance with the provision of the Animal Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences. Sprague Dawley (SD) rats were randomly divided into DL0805-2 low, medium, and high dose groups (1, 3, and 10 mg·kg^-1), bosentan positive control group, model group, and blank control group. The drug was administered daily on the 7th day after model establishment by monocrotaline injection. On the 25th day of the experiment, relevant indicators were examined to observe the therapeutic effect of DL0805-2 on pulmonary hypertension. DL0805-2 significantly relieved the abnormal changes in the physiological parameters related to PAH induced by monocrotaline, including reducing right ventricular systolic pressure, alleviating cardiac damage caused by pressure overload, and reducing the levels of endothelin-1 and inflammatory factors in lung tissues. DL0805-2 also attenuated pulmonary arteries remodeling. It was preliminarily discovered that DL0805-2 exerts preventive and therapeutic effect on PAH through Rho-kinase pathway. Our results suggested that DL0805-2 had good therapeutic effects on monocrotaline-induced PAH rat model. It intervened early in the disease process, effectively prevented the development of the disease, and reduced the mortality of the diseased animals. The mechanism is related to Rho-kinase pathway.
