Objective: To study the antibacterial activity in vitro of Sanhuang Shaoshangling on several common bacteria after changing the preparation process. Methods:Using the new technology of ethanol reflux extraction and water extraction, Sanhuang Sha-oshangling was prepared. A micro-broth dilution method was used to determine the minimum inhibitory concentration ( MIC) of San-huang Shaoshangling for escherichia coli, pseudomonas aeruginosa, staphylococcus aureus and type B paratyphoid salmonella after chan-ging the preparation process. The antibacterial effect of Sanhuang Shaoshangling prepared by the new and the old technology was com-pared, and the inhibition zone was detected by a paper strip method. Results:The antibacterial effect of Sanhuang Shaoshangling pre-pared by the new technology on escherichia coli, pseudomonas aeruginosa, staphylococcus aureus and type B paratyphoid salmonella was better than that of the products prepared by the old technology with the minimum inhibitory concentration ( MIC) of 16 μg·ml-1 , 16μg·ml-1 , 8 μg·ml-1 and 16 μg·ml-1 , respectively, while that of the product prepared by the old technology was 32 μg·ml-1 , 64 μg·ml-1 , 16 μg·ml-1 and 64 μg·ml-1 , respectively. Conclusion: The antibacterial effect of Sanhuang Shaoshangling after changing the preparation process is more significant, which shows certain clinical significance.

Objective To explore the clinical diagnositic code(CDC)in ovarian endometrial cysts (OEC).Methods 218 cases of pelvic masses were investigated by use of symptoms,signs,B mode sonography and CA125.172 cases were diagnosed with OEC out of 218 cases,While 46 cases were ruled out by combination exploratory laparotomy and laparoscopy.Meanwhile we compared it with revisional american fertility society(r-AVS)including diagnosis and staging.Results The operation results of 218 cases were compared with the results of CDC and its Diagnositic Sensitiveness;Specificness;Positive predictive value;Negative predictive value;Diagnositic accordance rate as well as Diagnositic index of CDC were 96.4%,79.6%.93.0%,90.0%,91.7% and 73.4% respectively(χ2=127.818,P＜0.001).Further more,172 cases of OEC which diagnosed with CDC were further subdivided into three stages as 1,2,3 according to its score,mild;moderate;heavy and this stage category were compared with the category of AFS(Ⅰ-Ⅱ,Ⅲ,Ⅳ),the Diagnositic accordance rate of two categories were 95.6%,95.6% and 83.0% respectively,No significant difference were found in Var.mitis and medium-sized(χ2=0,P＞0.05).but the Medium-sized and Gravis tape was significance(χ2=4.472,P＜0.05).Conclusion CDC has a better coincidence with operation in the diagnosis of OEC which can be used in the non-traumatic diagnosis and staging of OEC in clinic.

Systemic inflammatory response has a major role in the development and progression of cancer,and increased systemic inflammatory response usually correlates with poorer survival.Recently the evaluation index of systemic inflammatory response including neutrophil-lymphocyte ratio,C-reactive protein,glasgow prognostic score,platelet-lymphocyte ratio.Several previous studies show that these indexes are the independent prognostic factors for esophageal cancer.Research on the systemic inflammatory markers may also be valuable for the clinical treatment and prognosis of esophageal cancer.

Objective To investigate the etiology of papular urticaria: is it caused only by arthropod-like insects-bite allergy, or by multiple factors such as food allergy, disturbance of gastrointestinal function and infection? Methods We searched, by computer and manually, the foreign and domestic literature related to the etiology of papular urticaria published since 1950s, and according to the methods of evidence-based medicine, systematically evaluated the evidence supporting either the insect-bite theory or the multiple factor theory. Results Twenty-nine articles ( 22 English and 7 Chinese ) supported the theory of hypersensitivity to bites from certain insects such as mosquitoes, gnats, fleas, mites, bedbugs etc. Two articles in Chinese mentioned the possibilities other than insect-bite, but the reliability was unconvincing, because the authors did not present the source of data or statistical methods used in the articles. The evidence from epidemiology, histopathology, laboratory and clinical researches all supported the insects-bite theory. No proven evidence was found supporting other aetiological hypotheses. Conclusion Our results suggest that papular urticaria is caused only by the allergy to stings or bites of arthropods, and other hypotheses still lack convincing evidence.

Objective To evaluate the protective role of bone marrow stromal cells (BMSCs) to lactacystin-Parkinson's disease (PD) rats.Methods BMSCs were obtained from adult male SD rats and were expanded, isolated and purified. BMSCs were harvested from 4 to 6 passage and used for transplantation. PD rats that expressed Lewy body and presented lateral rotation were made by injecting 8?g lactacystin into one side of substantia nigra compact part of rat with stereotaxic technique. The rats were transplanted with BMSCs labelled by Brdu by stereotaxic unilateral injection into striatum and transplanted with normal saline as control. The behavior changes of rats and the expression of BDNF, migration, differentiation of BMSCs were examined.Results 71.43% of the rats displayed significant improvement of contralateral behavior after BMSCs transplantation, however there was no change in control group. BMSCs were found in several areas of the brain including striatum, corpus callosum and contralateral cortex. The implanted BMSCs expressed BDNF but no tyrosine hydroxylase.Conclusion BMSCs may play a neuroprotective role in lactacystin-PD rats by secreting BDNF.
