Objective To observe the clinical efficacy of application with raw Da Huang (Radix et Rhizoma Rhei) to umbilicus plus acupoint massage in treating functional constipation in patients who were receiving hemodialysis. Method Forty patients were recruited and randomized into an observation group and a control group, 20 in each group. The observation group was intervened by application to umbilicus with Chinese medication, while the control group was by oral administration of Rhubarb and Sodium Bicarbonate tablets. Result In the observation group, 16 were cured and the recovery rate was 80.0%;in the control group, 15 were cured and the recovery rate was 75.0%. There was no significant difference in comparing the recovery rate between the two groups (P>0.05). Conclusion Application with raw Da Huang (Radix et Rhizoma Rhei) plus acupoint massage can produce equal effect in treating constipation compared with laxatives, while application plus acupoint massage avoids the intake of too much water and the bitter taste brought by oral administration of drugs, and also avoids the risk of hyperkalemia induced by intake of Chinese medication.

In this paper a new type of cerebral circulation is introduced, including the basic principal, parameter algorithms and equipment design.

Objective To study the collision-induced dissociation fragmentation pathways of the jasminoidin and catalpol in ESI-Msn. Methods The samples were studied by using high performance liquid chromatography-electrospray ionization tandem mass spectrometry (HPLC-ESI-Msn) both in positive and negative. Results The collision-induced dissociation fragmentation pathways of both compounds were described. In the spectrum of two compounds, the loss of glucose residue and whole glucose were observed in positive mode, while only the loss of glucose residue could be observed in negative mode. Furthermore, we found that as the effect of the substituting groups, the fragment ions of jasminoidin were more in positive mode and those of catalpol were more in negative mode. Conclusion Conclusion The established method could be used for the sensitive and rapid identification of this kind of iridoid glycosides。

Background:Ulcerative colitis(UC)is often accompanied by a variety of extraintestinal manifestations. Recently, the role of extraintestinal manifestations in diagnosis and treatment of UC has aroused widespread concern in clinical practice. Aims:To study the extraintestinal manifestations of patients with UC in order to elevate diagnosis level of UC. Methods:A total of 208 inpatients from June 2008 to September 2011 at Beijing Military General Hospital were enrolled. The extraintestinal manifestations of UC were retrospectively analyzed. Results:The ratio of male to female was 1. 14: 1, mean age was(41. 17 ± 13. 57)years,mean disease duration was(62. 6 ± 79. 4)months. Thirty-three patients had proctitis,52 had left-sided colitis,and 123 had extensive colitis. Forty-nine patients were mild UC,80 were moderate UC, and 79 were severe UC. The incidence of extraintestinal manifestations was 28. 8%(60 / 208);13 patients(6. 3% )had more than one extraintestinal manifestation. The main extraintestinal manifestations were oral ulcer(13. 0% ),arthropathy (11. 1% ),hepatobiliary disease( 3. 8% ) and skin lesion( 1. 4% ). The trend of incidence of extraintestinal manifestations increased from patients with proctitis,left-sided colitis to extensive colitis(21. 2% ,28. 8% ,30. 9% , respectively),however,the difference was not statistically significant(P > 0. 05). No significant difference in incidence of extraintestinal manifestations in patients with mild UC,moderate UC and severe UC was found(22. 4% ,33. 8% ,27. 8% , respectively)(P > 0. 05). Conclusions:Patients with UC are often accompanied by extraintestinal manifestations,and the recognition of extraintestinal manifestations is helpful for improving diagnosis and treatment level of UC.

This report presented a case of 62-year-old woman who was admitted to our hospital for cirrosis, but she had a variety of clinical manifestations,such as abdominal distension,diarrhea,ascites, hepatosplenomegaly,anemia, palpitation, flushing, low blood pressure, arrhythmia and so on. Upper gastrointestinal endoscopy showed thicken mucosa at gastric fundus. Colonoscopy revealed nodular, pseudopolypoid. Ascitic fluid test suggested a transudate. Endoscopic abnormal mucosa biopsy showed chronic inflammation. Many mast cells were seen in bone marrow and liver biopsies,and liver tissue immunophenotype was CD117, and CD68. Thus the patient's diagnosis was systemic mastocytosis. It is rare that a patient only has the gastrointestinal tract symptoms complicated with ascites without skin lesion. The goal for treatment was to reduce hypersecretion of mast cells.

This study was aimed to establish a method for the rapid content determination of Ixerin Z and 11,13α-dihydroixerin Z in Ku-Die-Zi (KDZ) injection by UPLC-ESI-MS/MS. The separation was performed on a Waters ACQUITY BEH C18 column (2.1 mm × 50 mm, 1.7μm) by using a gradient elution with the mobile phase of acetonitrile-water at the flow rate of 0.4 mL·min-1. The column temperature was set at 40℃. Multi-reaction moni-toring (MRM) scanning was employed for quantification in ESI negative mode. The results showed that two sesquit-erpene lactones in KDZ injection were totally separated within 2 min. The linear range of Ixerin Z was 5.70-182.50 ng·mL-1, and the linear range of 11,13α-dihydroixerin Z was 4.60-131.25 ng·mL-1. The correlation coefficient r was more than 0.999 0. The recovery rates (n = 6) were 98.18% and 97.52%, with RSDs < 1.5%. The established method was successfully applied for simultaneous content determination of Ixerin Z and 11,13α-dihydroixerin Z in 6 batches of KDZ injection from 2 factories, which had some variations on the content determination results. It was concluded that the method was rapid, accurate and sensitive, which can be used for the content determination of two sesquiterpene lactones in KDZ injection.

Objective To investigate the effects of estrogen on mismatch repiar gene expression in colonic mucosa in vivo. Methods A total of 42 healthy individuals underwent colonoscopy were enrolled in the study. Half an hour before colonoscopy examination, blood sample was taken for determining the serum estradiol (E2) level. N ormal colonic mucosal tissues determined by naked eye under colonoscopy examination were taken in the right hemi colon to detect HMLH1 and hMSH2 gene expression by semi-quantitative RT-PCR and immunohistochemistry staining. Then the correlation of serum E2 levels with hMLH1 and hMSH2 expression in colonic mucosa was analyzed. Results A bimodal curve was presented for the correlation between serum E2 level in healthy individuals and hMLH1 expression in colonic mucosa. A strong positive correlation of E2 level with hMLH1 expression in normal colonic mucosa was observed when serum E2 level was more than 45 pg/ml (For mRNA, P=0. 003, r=0. 701; for immunohistochemistry positivity index, P=0. 000, r=0. 874).However there was no correlation between E2 level and hMSH2 expression. Conclusion High serum E2 level might increase the hMLH1 gene expression in colonic mucosa in vivo.

Objective To investigate the effect of different sealing methods of urokinase plus heparin on long-term dialysis catheter thrombolysis.Methods63 patients were treated with maintenance hemodialysis from central venous catheters with catheter thrombosis as a clinical study.The patients were divided into observation group and control group by simple random method.In the observation group, 31 cases were treated with urokinase and heparin mixed solution from the ends of the arteriovenous catheter of permanent double-laryngeal dialysis tube for 24 hours for 3 consecutive days.32 patients in the control group, from the permanent dual-chamber dialysis catheter arterial and vein at both ends with a micro pump pumped urokinase, maintained for 2hours.ResultsThere was no significant difference in thrombolytic success rate between the two groups.The catheter retention time in the observation group was significantly longer than that in the control group, the dialysis blood flow rate, the solute clearance index and the urea clearance index were significantly higher than those in the control group.The incidence of venous pressure and hemorrhagic adverse events was significantly lower than that of the control group (P<0.05).ConclusionUrea kinase plus heparin mixture is simple and easy to operate, which avoids the risk of excessive localized or systemic hemorrhage caused by excessive urokinase into the blood circulation of patients.It is worthy of popularization.

Objective: To observe the clinical efficacy of photodynamic therapy on oral leukoplakia in elderly patients. Methods: In this prospective study, fifteen elderly patients with oral leukoplakia were treated with 5-aminolevulinic acid-based photodynamic therapy(ALA-PDT). After 2 hours of dressing, patients were irradiated using a 635nm semiconductor laser with the power density of 300mW/cm².Each lesion was irradiated for 6 minutes with energy density of 100J/cm².The curative effect was evaluated and the adverse reactions were recorded based on the observation of lesion changes. Results: Of the 15 lesions in 15 patients, 4 lesions were treated once, 3 lesions were treated twice.And 6 lesions were cured after three treatments, and 2 patients were cured after four treatments.The average treatment frequency was(2.4±1.1)treatment.The postoperative adverse reaction was pain.The average visual analogue scale was(2.2±0.8)scores after operation, and the duration of pain was(2.6±1.1)days after operation.There was no recurrence for 3 to 9 months after operation.No abnormalities of oral sensation and function were found in patients. Conclusions ALA-PDT is an effective method for the treatment of oral leukoplakia in elderly patients.
