OBJECTIVE:To study pharmacodynamics of different approaches of using low peptide of E’ jiao. METHODS: Anemia model rabbits and immunosuppressed model mice were induced by injecting with phenylhydrazine hydrochloride subcutaneously and hydrocortisone via i.p. respectively then treated with low peptide of E’ jiao (1～3 kD) via i.p., low peptide of E’ jiao of lower than 5 k and 5% E’ jiao solution via i.g. The values of Hb, RBC, WBC in model rabbits were measured after 7 days of medication and spleen weigh index was detected after 6 days of medication. The healthy mice were treated with low peptide of E’ jiao (1～3 kD) via i.p., low peptide of E’ jiao of lower than 5 k via i.g. and glucose solution via i.g. Then the load swimming time was determined after 14 days of medication. RESULTS: Chemical medicine-induced anemia was improved by 1～3 kD low peptide of E’ jiao increasing the amount of Hb. Low peptide of E’ jiao of lower than 5 k could not produce such an good effect on anemia but was eaqul to oral E’ jian in increasing the value of RBC, WBC. Low peptide of E’ jiao was helpful to or had effect on anti-fatigue and remarkably increased spleen index of mice. CONCLUSION: Low peptide of E’ jiao used by different approaches can strengthen immunity.

OBJECTIVETo verify the clinical efficacy on post-stroke dysphagia treated with acupuncture at Lianquan (CV 23).

METHODSOne hundred and eighty patients were randomized into an acupuncture A group, an acupuncture B group and a rehabilitation group, 60 cases in each one. On the basis of the conventional medication, in the acupuncture A group, acupuncture was applied at Lianquan (CV 23); in the acupuncture B group, acupuncture was applied at Hegu (LI 4) and Neiguan (PC 6) and in the rehabilitation group, the swallowing rehabilitation training was adopted. The treatment was given once a day, 5 times a week, and the 4 weeks of treatment was required in all of the groups. The national institute of health stroke scale (NIHSS) and TV X-ray fluoroscope swallowing scale (VFSS) were used to evaluate neurologic deficit and swallowing function before and after treatment in the patients of each group. The morbidity of pneumonia and clinical efficacy were compared among the groups.

RESULTSThe scores of NIHSS and VFSS were improved apparently after treatment in the patients of the three groups (all P < 0.05) and the results in the acupuncture A group were superior to those in the other two groups (all P < 0.05). The morbidity of pneumonia in the acupuncture A group was lower than that in the acupuncture B group and the rehabilitation group [3.3% (2/60) vs 6.7% (4/60), 8.3% (5/60), both P < 0.05]. The effective rate in the acupuncture A group was better than that in either of the other two groups [95.0% (57/60) vs 81.7% (49/ 60), 75.0% (45/60), both P < 0.05].

CONCLUSIONOn the basis of the conventional medication, acupuncture at Lianquan (CV 23) effectively improves the swallowing function, relieves neurological deficit and reduces the morbidity of pneumonia in the patients of post-stroke dysphagia.

Objective To evaluate the variation of functional urethra length on urine control,explore a new method to prevent urinary incontinence and seek urodynamic evidence after radical prostatectomy. Methods Sixteen male dogs,matched in body weight,were randomly divided into two groups. Group A were used to test the different rest urethral pressure profile after resection of prostate,resection of distant prostate plus posterior urethra in length of 1.5 cm and 2.0 cm respectively; Group B to test the different rest urethral pressure profile on pedicle myotube in length of 2.0 cm and 1.0 cm using anterior bladder flap respectively after resection of prostate and posterior urethra in length of 2.0 cm. Results The urodynamic indexes fell off while the functional urethra length decurtated gradually in group A,but they went up in group B. The two groups showed significant difference before and after the resection of prostate and distant urethra in length of 2. 0 cm. Conclusion There was a direct ratio between the functional urethra length and the capability of urethral urine control. Reconstruction of functional urethra using anterior bladder flap pedicle myotube is a good choice to treat urinary incontinence after radical prostatectomy.

To study the nodal distribution in endometrial carcinoma and to evaluate its effect on recurrence and survival, 230 patients with endometrial carcinoma were reviewed and analyzed. 32(20 25%)cases were found to have lymph node metastasis. Stage Ⅲc disease was defined by positive PLN alone in 22 cases, positive PLN and PALN in 4 cases, and positive PALN alone in 6 cases. Positive peritoneal cytology and adnexal metastasis were present in 10 patients. Only 2/10 of these patients had isolated positive PLN whereas 8/10 had positive PALN ( P 0 05). These findings indicate that PALN involvement is common in patients with FIGO Stage Ⅲc endometrial cancer, and suggest that PLN sampling alone may result in underdiagnosis of disease, and dissection of PALN may have a significant therapeutic role.

Objective To analyze the causes of misdiagnosis of uterine sarcomas and to explore the measures to reduce these errors. Methods A retrospective study of 40 cases of uterine sarcomas admitted between January 1980 and June 2002 to our hospital was performed. Results Uterine sarcomas were easily misdiagnosed as leiomyomas. A correct diagnosis of uterine sarcoma was made at primary operation in 15 cases (37.5%). A wrong diagnosis was made in 25 cases (62.5%), and among them re-operation was done in 15 cases. In 7 patients, three operations were performed. Recurrence rate was as high as 64.0%. The rate of hematogenous dissemination was also high. The patients in whom a misdiagnosis was made at their primary operation were younger in age than the patients in whom a correct diagnosis was made (43 years vs 50 years). The amounts of bleeding and transfusion during operations were increased in patients with misdiagnosis. Conclusions Atypical manifestations and lack of knowledge about the diseases were the main causes for misdiagnosis of uterine sarcomas. Misdiagnosis might be avoided by a comprehensive analysis of all clinical information. Radical resection of the primary tumor was the most significant means to ensure a better prognosis.

Objective To investigate the etiology,clinical charactieristics,treatment and prognosis in pediatric hemoptysis to provide reference for its diagnosis and treatment to pediatric doctors .Methods The retrospective analysis was performed on the clinical manifestations ,laboratory tests ,imagiological and bronchoscopic manifestations ,treatment methods and outcomes in the children patients with hemoptysis as the chief complaint admitted to our hospital from April 2009 and December 2014 .Results A-mong 102 children cases of hemoptysis ,55 cases were male and 47 cases were female .The median age was (7 .05 ± 1 .2) years old . Mild hemoptysis was in 87 cases(85 .3% ) ,moderate hemoptysis was in 10 cases(9 .8% ) and massive hemoptysis was in 5 cases (4 .9% ) .The relatively exact causes of hemoptysis were found in 88 cases ,in which the lower respiratory tract infection was most common ,the top 3 causes were pneumonia ,pulmonary tuberculosis and bronchitis .In the non-infection causes ,idiopathic pulmonary hemosiderosis(IPH) was most common ,while connective tissue diseases ,pulmonary vascular malformation and airway foreign body were rare .85 cases showed different pathological lesions on chest CT scan .Among the 35 cases underwent the bronchoscopy ,3 ca-ses of bronchial stenosis caused by granulation proliferation was improved after bronchoscopic cryotherapy ,5 cases of active bleed-ing under endoscopic stopped bleeding by topical hemostasis ,among 10 cases of suspected tuberculosis with negative sputum bacte-ria ,acid-fast bacilli was found in 8 cases by bronchofiberscopic lavage .The treatment of pediatric hemoptysis was dominated by the medical etiological and symptomatic therapy .Conclusion Chest CT scan can provide a very important basis for the etiological diag-nosis of hemoptysis and the bronchoscopy examination also has an important value in the diagnosis and treatment of hemoptysis . The etiological and symptomatic treatment is predominat in pediatric hemoptysis ,and the majority have good prognosis .

Objective To investigate the effect of pioglitazone on the expression of thrombospondin-1(TSP1)and transfor ming growth factor-β1 (TGF-131)in the kidney of diabetic rats.Methods Forty Sprague-Dawley(SD)rats were randomly divided into 4 groups:normal control(NC),streptozocin-induced diabetic mellitus(DM),diabetic rats treated with pioglitazone(DP)and normal control rats treated with pioglitazone(NP).24-h urine protein quantity,serum creatinine(Scr) and kidney hypertrophy index were measured after treatment for 10 weeks,and the expression of TSP1 and TGF-β1 in the kidney was detected by using RT-PCR and immuohistochemistry.Results As compared with DM group,urine protein level and kidney hypertrophy index were significantly attenuated in DP group(P<0.05),but there was no significant difference in plasma glucose between them(P>0.05).As compared with NC and NP groups,the expression of TSP1 and TGF-β1 was significantly elevated in the kidney of DM and DP groups(P<0.01).Both TSP1 and TGF-β1 expression in DP group was lower than in DM group(P<0.05).Conclusion Pioglitazone can exert a direct protective effect on the kidney in diabetic rats,which is independent of the role of insulin sensitizer,and the mechanism may be associated with the decreased TSP1 expression in the kidney.

BACKGROUND:Cord tissues,which immune system is relatively non-development with low expression of MHC,rely on the protection of the mother's immune system.Accordingly,studies underlying biological characteristics of umbilical cord mesenchymal stem cells (MSCs) arouse more and more attention.OBJECTIVE:To isolate,separate,and culture MSCs from the tissues of umbilical cord,and to explore the ability of multi-directional differentiation.DESIGN,TIME AND SETTING:The in vitro cytology experiment was performed at the Laboratory of Tissue Engineering of Sichuan University from October 2006 to May 2007.MATERIALS:The umbilical cord of healthy neonate with 37-40 weeks gestational age was obtained from delivery room of the Second West China Hospital,Sichuan University.METHODS:Pieces of umbilical cord were dissected along its long axis,vessel was pulled away,then cord was tied together with a suture creating "loops",then it was placed into collagenase solution,after 6-8 hours,suspended cells obtained from the loops suspension were centrifuged and cultured with adherent method,pass,aged when single cell-derived colonies were appeared.Finally,the 5th generation of cells was induced differentiation towards osteoblasts and lipoblasts.MAIN OUTCOME MEASURES:Morphology,growth,surface antigen expression,as well as the multiple differentiation potential of umbilical cord MSCs.RESULTS:The adherent cells obtained from umbilical cord after removal vessels showed short rod-like or fusiform shape,which can be proliferated and form single cell-derived colonies.Cells isolated from the umbilical cord high expressed integrin markers (CD29,CD51,CD71) but not hematopoietic lineage markers (CD34,CD45 and HLA-DR).These colonies can differentiate into osteoblasts that produce mineralized matrices,stained by alizarin red and alkaline phosphatase,and differentiate adipocytes that accumulate lipid vacuoles and are demonstrated by morphology,stained by oil red.CONCLUSION:Umbilical cord tissue contains a high number of MSC-like elements forming colonies that may be successfully expanded in culture.The proliferation colonies present matrix ceil immunophenotypes,and can differentiate into osteobiasts and adipocytes.
