Introduction: Gallstones disease is a common disorder and symptomatic disease is usually managed with surgery while those with common bile duct stones are usually managed with endoscopic intervention before proceeding to surgery. This study was intended to assess the rate of cholecystectomy among patients who had undergone ERC interventions, the reasons for not proceeding to cholecystectomy and related complications. Materials and Methods: Patients who had intact gallbladder and had undergone ERC for stones related complications over a two year period were retrospectively identified from the Endoscopic Unit Registry. Detailed case note reviews were conducted. Results: The overall cholecystectomy rate post-ERC interventions was 36.9% (48/130). Cholecystectomy was offered to 59.2% (n=77) and the uptake was only 58.4% (n=45/77). Among those who agreed for cholecystectomy, 11.1% (n=5/45) failed to turn up for their scheduled surgery. Three patients (6.7%) had symptoms recurrence before their scheduled surgery: two subsequently underwent cholecystectomy without ERC intervention and one who was pregnant was managed conservatively with holecystectomy. Among the patients who had declined cholecystectomy, 18.8% (n=6/32) had symptoms recurrence. Four patients required repeat ERC interventions and eventually all had cholecystectomy subsequently. The most common reason for declining cholecystectomy was 'not keen' and already asymptomatic (46.9%, n=15/32). Among patients who were not offerred cholecystectomy (n=53/130), symptoms recurrence occurred in 15.2% (n=7/53). Four patients required repeat ERC interventions and three subsequently underwent cholecystectomy. Conclusions: The cholecystectomy rate remains low after ERC interventions. Recurrence of symptoms necessating re-interventions occurred in patients offerred and not offerred cholecystectomy. The uptake rate should be improved and delay to cholecystectomy should be reduced to avoid symptoms recurrence. Patients not undergoing interventions should be advised regarding symptoms recurrence and should be monitored.

Objective To investigate the prevalence,radiological features and the association between HRCT changes and different diseases or clinical features in interstitial lung disease(ILD)caused by diffuse connective tissue diseases(CTD).Methods Retrospective analysis was performed based on the medical records of 412 in-patients with the diagnosis of diffuse connective tissue diseases from June 2003 to June 2005 in our hospital.268 cases were SLE,83 cases were SS,40 cases were DM/PM,21 cases were SSe.All patients had chest X-ray and the suspected cases had HRCT exam.The distribution of ILD among different diffuse CTD.the appearance between X-ray and HRCT appearances were compared.The correlation among HRCT appearance,different diseases and clinical features was studied.Results①In the 412 cases of CTD,ILD de- tected by HRCT was 9.7%(40 case in total),3,9% by X-ray.Among the 40 cases,DM/PM had the highest rate of ILD(25%),23.8% in SS,9.6% in SS and 6.3% in SLE.②The consensus rate between HRCT and X-ray was 40%.The rate of mis-diagnosis of ILD was 60% by X-ray.③The changes of interstitial involvement de- tected by HRCT were:ground glass change(41.0%),consolidation(32.8%),reticular change(16.4%)and hon- eycomb change(9.8%).The concomitant presence of two of the above changes were very common.④More level respiratory symptoms such as cough,panting,chest distress and chest pain and high level of complement were observed in patients with ground glass and consolidation changes,while high CRP level was seen in patients with consolidation and honeycomb changes(P

Objective To explore the effect of patients with acute cerebral infarction and complication of acute gastric mucosal lesions (AGML) on their short-term prognoses.Methods Two hundred and sixteen patients with acute cerebral infarction admitted to the Department of Neurology in Tianjin Nankai Hospital from January to December 2014 were enrolled, and they were divided into the control group without AGML (167 cases) and observation group with AGML (49 cases) according to whether AGML occurred or not. The digestive tract was monitored in the two groups, and the relationships between the incidence of AGML and the location of infarction, stroke classification, as well as the anti-thrombosis treatments like thrombolysis, anti-coagulation and anti-platelet, etc. were analyzed; the changes in scores of the National Institutes of Health Stroke Scale (NIHSS) on admission, 7 days and 14 days after onset and 14-day mortality of two groups were compared.Results AGML occurred in 49 of 216 patients (22.69%); the 14-day mortality of the observation group was obviously higher than that of the control group [6.12% (3/48) vs. 1.80% (3/167),P < 0.05], the incidence of infarction located in cerebellum, brainstem, multiple cerebral lobes, etc. (low density shadow > 1/3 hemispheres) in the observation group was higher than that in the control group [cerebellum: 18.37% (9/49) vs. 4.19% (7/167); brainstem: 24.49% (12/49) vs. 8.98% (15/167), multiple lobes: 16.33% (8/49) vs. 2.99% (5/167), all P < 0.05]; the incidence of cardiac cerebral embolism (CE) was significantly higher than that in the control group [55.10% (27/49) vs. 12.57% (21/167),P < 0.05]. With the extension of disease course, the NIHSS score of the observation group was increased, while the score of the control group was gradually reduced, and the NIHSS scores of the observation group were obviously higher than those of control group on the 7th and 14th day after onset (7 days: 18.12±4.20 vs. 10.93±6.73, 14 days: 19.33±3.11 vs. 9.66±9.15, bothP < 0.05). The thrombolysis, argatroban anti-coagulation and anti-platelet incidence between the two groups after treatments was of no statistically significant difference (the incidence in control group was 4.79%, 47.31%, 47.90%, and it was 4.08%, 44.90%, and 48.98% in observation group, allP < 0.05). Conclusion The occurrence of AGML complication in patients with acute cerebral infarction is closely related to their short-term prognoses, and when the cerebral embolus is cardiac in origin or the infarction is located at multiple cerebral lobes, brain stem or cerebellum, the probability of the occurrence of AGML is relatively high, suggesting a poor outcome.

With the development of therapeutic antibodies over the past decade, they have become the treatment options for immunity and inflammation diseases. Major limitations of mouse antibodies as therapeutic agents - immunogenicity, lack of effectors' functions and short serum half-life -- were subsequently identified and largely overcome by the advent of humanized and fully human antibody technologies. The therapeutic antibodies for immunity and inflammatory diseases are primarily utilized in the treatment of allograft rejection, autoimmune disease, autoinflammatory syndromes, allergies and other chronic inflammation. The action mechanisms of therapeutic antibody include blocking ligands or receptors, regulating receptor activity, clearing the target cells or activating receptor. Strategies for generating the antibody drugs with high efficacy and low side effects can be realized by modulation of Fc-mediated activities and optimization of antigen-binding domains.

1-(2,6-Dimethylphenoxy)-2-(3,4-dimethoxyphenylethylamino) propane hydrochloride(DDPH) caused parallel rightward shifts of the phenylephrine(Phe) concentration-contractile response curves and did not suppress the maximal contractile response to Phe (pA2=7.24) in isolated rabbit urinary bladder smooth muscle. DDPH decreased the parameters of cystometry in urethane-anesthetized rats. Thirty minutes after DDPH (25 and 50 mg*kg-1 ig) administration, bladder capacity, voiding pressure, voiding threshold pressure were significantly decreased. With the observation of light-microscope and electron-microscope technique, DDPH (25 and 50 mg*kg-1*d-1 ig for 4 weeks) also inhibited the development of testosterone propionate-induced benign prostatic hyperplasia in rats. The results indicate that DDPH may inhibit benign prostatic hyperplasia and improve the urinary flow.
