Objective To evaluate the curative value of the tauroursodeoxycholic acid (TUDCA) and Danning table (DN) in the prevention of bile duct stones recurrence after ERCP. Methods 210 patients with Choledocholithiasisby ERCP were randomly divided into 3 groups. The patients in the control group were not given any medicine. The patients in the TUDCA group took TUDCA every night. The patients in the DN group took Danning tablets of three times a day. The course of medication and followed up for the patients was 24 months after the operation. All the patients would be examined regularly by Biliary color doppler ultrasound and MRCP. The recurrence rates of Choledocholithiasis, cholesterol saturation index and serum lipid were recorded and compared statistically between the three groups. Results In total, 190 patients completed the treatment and follow-up according to the experimental design. The recurrence rates of the control, TUDCA and DN group were 17.46%(11/63), 6.34% (4/63) and 10.94% (7/64). The recurrence rates in the TUDCA and DN group were significantly lower than those the control group (P < 0.05).The recurrence rate in the TUDCA group was significantly lower than that in the DN group; On the tenth days after the operation, the CSI in the TUDCA were significantly lower than those the control group and the DN group (P < 0.05). There was no statistically significant difference between the DN group and the control group (P > 0.05); To the patients without recurrence, the level of TC, LDL in the TUDCA group were significantly lower than those the control group and and the DN group (P < 0.05). The level of HDL in the TUDCA group were significantly higher than those the control group and and the DN group (P < 0.05). There was no statistically significant difference on the level of HDL between the DN groupand the control group (P > 0.05). Conclusion The application of TUDCA and DN for patients with Choledocholithiasis after ERCP can effectively reduce the recurrence rates, the curative effect of TUDCA more than DN.

Objective To prepare pH sensitive gel for eye cornea of salvianolic acid B and accomplish in vitro release study. Me thods We used corneal permeability, eye irritation in rabbits, hydration of the cornea, viscosity, gel capacity, transparency, liquidity as index, to select pH sensitive gel matrix composition. Re s ults The gel composition was: 0.5％ of salvianolic acid B, 0.14％ Carbomer, 0.3％ HPMC, 0.05％ Azone, 0.1％ ethylparaben and 0.2％ Vc. The corneal hydration level was 77.32±1.88.The gel released 27.21％ drug in 15 min, and released 97.44％ drug in 6 h. By research of corneal permeability, the cumulative release of gel was bigger than the one of saline (P＜0.05). Conclus ions The selection of the gel matrix prescription is reasonable in design, simple in process, not harsh to eyes, and can prolong the retention time of drug in corneas and improve the corneal penetration.

Objective To explore the use of Diagnosis Related Groups(DRGs)evaluation index in performance management system of hospitals.Methods The performance evaluation system was built based on medical business volume index,efficiency indicators,cost control indexes,drug control indexes, medical quality and medical safety indexes,by means of extracting the home page of hospital discharge records from 2009 to 2013 and grouping automatically with the“BJ-DRGs”group-maker.Results The operation evaluation indexes of the hospital have seen great progress since advent of the DRGs evaluation indexes.Conclusion Introduction of DRGs has scored great success in the performance appraisal system of the hospital.

ObjectiveTo discuss the central modulating mechanisms while acupuncturing the Stomach 36[ST36(Zusanli)]by brain functional imaging with positron emission tomography (PET).MethodsPET imaging of whole brain was performed in a group of six healthy subjects during two stimulation paradigms: pseudo acupuncture and real acupuncture at acupoint ST36(Zusanli). The data on cerebral glycometabolism,obtained by using PET,was analyzed by using statistical parametric mapping (SPM).ResultsThere was certain increase of glycometabolism in ipsilateral hypothalamus,back of medulla oblongata;bilateral insular lobe; contralateral paracentral lobule,superior part of precentral and postcentral gyrus,opercular part of frontal and temporal lobe,middle part of cingulate gyrus,head of caudate nucleus,middle part of the back of midbrain and pons,and deep part of cerebellum,whereas decrease in ipsilateral superior part of precentral and postcentral gyrus and lateral part of ipsilateral anterior cerebellar lobe,while acupuncturing at acupoint ST36(Zusanli on the right leg).ConclusionsThe central modulating mechanisms of acupuncturing ST36 are realized by neural and neuroendocrine network modulation mechanisms of vegetative nerve center in cortex and subcortex.

OBJECTIVETo explore the diagnosis, treatment, and prognosis of prostatic malignant mesenchymal tumors (PMMT).

METHODSWe retrospectively analyzed the clinical and follow-up data about 20 cases of PMMT and reviewed the literature relevant to the diagnosis, treatment, and prognosis of the disease.

RESULTSBased on the results of pathology and immunohistochemistry, the 20 PMMT cases included leiomyosarcoma (n = 7), rhabdomyosarcoma (n = 5), prostatic stromal sarcoma (n = 3), chondrosarcoma (n = 1), and undifferentiated PMMT (n = 4). Twelve of the patients were treated by radical prostatectomy (3 concurrently by sigmoid colostomy and 1 by cystostomy), 2 by pelvic tumor resection following arterial embolization, 1 by total pelvic exenteration, 1 by colostomy with pelvic lymph node biopsy, and 4 by conservative therapy because of metastasis to the lung, pelvis and bone. Of the 20 patients, 9 died of systemic metastasis within 3 months after treatment, 3 died at 6, 7, and 14 months, respectively, 3 survived with tumor for 5, 11, and 12 months, respectively, 2 survived without tumor for 12 and 24 months so far, all subjected to periodic chemotherapy postoperatively, and 3 lost to follow-up.

CONCLUSIONPMMT is a tumor of high malignancy and rapid progression, for which transrectal ultrasound-guided biopsy remains the main diagnostic method. The clinical stage of the tumor is an important factor influencing its prognosis and the survival rate of the patients can be improved by early diagnosis and combined therapy dominated by radical prostatectomy.

OBJECTIVETo investigate the correlation of the degrees of intravesical prostatic protrusion (IPP) measured by transabdominal ultrasound with the clinical evaluation parameters in BPH patients.

METHODSWe measured the length of IPP in the mid-sagittal section by transabdominal ultrasound in 275 BPH outpatients with lower urinary tract symptoms, and analyzed the correlations of the degree of IPP with the age, prostatic volume (PV), international prostatic symptom score (IPSS), maximum uroflow rate (Qmax), and postvoid residual urine volume (PVR) of the patients.

RESULTSThe degree of IPP was correlated positively with the age (r = 0.210, P < 0.01), PV (r = 0.534, P < 0.01) and PVR (r = 0.314, P < 0.01), but negatively with the Qmax (r = -0.364, P < 0.01) of the BPH patients. There was no significant correlation between the degree of IPP and IPSS (r = 0.064, P = 0.299).

CONCLUSIONThe degree of IPP may be associated with the age and prostatic volume of BPH patients. Transabdominal ultrasound measurement of IPP is a useful noninvasive method to assess the presence and severity of bladder outlet obstruction in BPH patients.

OBJECTIVETo observe the effects of Stragalus membranaceus injection on nitric oxide and endothelin levels of intestinal mucosa in reperfusion injury after hemorrhage shock.

METHOD32 SD rats were randomly divided into four groups: normal group, model group, low dosage group, (treated with Astragalus membranaceus 10 g x kg(-1)); high dosage group (treated with Astragalus membranaceus 20 g x kg(-1)). Models of hemorrhagic shock for 60 minutes and reperfusion for 90 minutes were created. The animals were administrated 3 mL therapeutic solution before reperfusion. At the end of study, intestinal pathology was observed, and the concentration of lactic acid (LD), nitric oxide (NO), endothelin (ET) of intestinal mucosa were detected.

RESULTThe intestinal pathology showed that intestinal mucosa epithelial cells damage in model group was severe, in low dosage group was medium, in high dosage group was slight, and no obvious damage was found in normal group. The concentration of LD and NO of small intestine mucous membrane in model group and low dosage group were significantly higher than those in high dosage group and normal group (P < 0.05), but there were no significant differences between high dosage group and normal group (P > 0.05). The concentration of ET of small intestine mucous membrane in model group was the highest of the four groups (P < 0.05). The concentration of ET in low dosage group was significantly higher than that in high dosage group and normal group (P < 0.05), but there were no significant differences between high dosage group and normal group (P > 0.05).

CONCLUSIONStragalus membranaceus injection can reduce small intestine mucous damage by protecting endothelium function in injury after hemorrhage shock-reperfusion.

OBJECTIVETo investigate the expression of epidermal growth factor receptor (EGFR) during the mineralization of human periodontal ligament cells (hPDLC) in vitro.

METHODSStudies using specific antibodies to immunolocalize EGFR in the mineral differentiating hPDLC were undertaken to investigate the different expression during the inducing process. In situ hybridization and RT-PCR technique were used to investigate the transcripts encoding the protein of EGFR.

RESULTSThe results showed that immunocytochemical labeling gradually decreased following the elong of the induce time, downing to nearly negative at the 4th week and the signal of EGFR transcripts was weaker in the induced hPDLC than that in uninduced.

CONCLUSIONEGFR has a negative regulation function during the mineralization of hPDLC.
