ABSTRACT
Alongside the social and economic development in China, medical risks, economic risks, and legal risks rise as well in the management of public hospitals. However, the capabilities of these hospitals in prevention and control of medical risks and disposal of legal affairs fall far behind the increasingly complex legal affairs. In this consideration, the authors introduced their innovative practice in taking legal actions for prevention and control of medical risks in the hospital, analyzed the problems found in medical legal affairs, and put forward specific suggestions to promote the standardization and modernization of hospital legal affairs.
ABSTRACT
Objective To retrospectively analyze the implementation of the antimicrobial agents prescription monthly review at the emergency and outpatient departments for the past five years, for evaluation of its action in promoting rational application of antimicrobial drugs. Methods At the baseline investigation stage, 1780 prescriptions on antibiotics in emergency and outpatient department from June 2012 to November 2012 were randomly selected for centralized evaluation. The period of correction and observation falls into two stages. The first stage ranged from December 2012 to February 2015, when the prescription of antibiotics was sampled manually for monthly review. The second stage ranged from March 2015 to June 2017, when a prescription review software for prescription comment was introduced for the sample purpose. The data so acquired were subject to chi-square test and linear regression analysis using Excel 2010 and SPSS 16. 0. Results The rational rate of prescription for antibiotics at the emergency department increased from 80. 56％ of the baseline stage to 99. 47％ of the second stage (166506/167400), scoring a difference of statistical significance (P<0. 001). With intervention of the prescription review software, the percentage of irrational use of antimicrobial agents dropped by 5. 18％ compared to the baseline stage. Conclusions Monthly prescription review on antimicrobial agents at the outpatient and emergency departments could promote the rational use of antimicrobial agents and play an important role in clinical drug safety. Information system and performance assessment contributed to the effect of prescription review.
ABSTRACT
The medical management department of individual hospitals varies with their organizational structure and operational mechanism, instead of following a general pattern. Inspired by the"super-ministry" system of government,the hospital has integrated successively the Medical Affairs Office, Patient Safety Office,Medical Quality Control Office,Hospital-acquired Infection Control Office and Medical insurance office. Through integration and innovation of duties, regulations, culture, decision-making progress,coordination and talent training mechanism, the " Five-in-One" super-ministry model of medical management came into being,achieving collaborative and efficient medical management as a result.

ABSTRACT
Objective To investigate the differences of four equations to estimate glomerular filtration rate (GFR) and their impacts on chronic kidney disease (CKD) prevalence in communitydwelling elderly people in Beijing.Methods A total of 489 participants aged above 70 years were enrolled.The GFR was estimated using the Cockcroft Gault (CG) equation,Chronic Kidney DiseaseEpidemiology Collaboration (CKD-EPI) equation,Modification of Diet in Renal Disease (MDRD) equation and Berlin Initiative Study (BIS) equation respectively.The internal-consistency check was made on the four equations for the GFR (ml min 1 1.73m 2) estimates.Results The mean age of participants was (81.8±7.6) years.The mean GFR estimated using the CG,CKD-EPI,MDRD and BIS equation was 58.4± 17.2,71.9± 15.3,76.7± 19.1 and 62.7± 12.7,respectively.And the prevalence of CKD was 56.2％,22.7％,17.8％ and 41.7％,respectively.The greatest differences of equations to estimate GFR were seen in elderly people aged 90 and above,and those with body mass index＜ 20.0 kg/m2 or serum creatinine concentration＜ 88.4 μmol/L.Conclusions The GFR estimated using different equations has a large difference which has a significant effect on CKD classification in elderly people.The equation to estimate GFR for the elderly is urgently needed.Until then,the eGFR and CKD classification estimated using different equations should be regarded with caution.
ABSTRACT
As the basis of the health management of the elderly, weight management should receive attention from medical practitioners.However, there is an ongoing debate on the ideal range of body mass index for elderly in China.This article aimed to find the suitable body mass index for Chinese old people by reviewing the literature regarding the body mass and obesity of the elderly.Lots of evidence show that overweight and mild obesity appear to be the optimal weight status for the elderly.
ABSTRACT
Objective To summarize the clinical features, diagnosis and treatment of autoimmune pancreatitis (AIP). Methods From March 2003 to January 2008, a total of 16 cases of AIP were reviewed retrospectively. Results The ratio of male: female was 15:1, with a mean age of 61 years old (range:47-79 years old). Jaundice was the main clinical presentation in 81.2% patients. 68.8% patients presented with high serum gammaglobulin, while 66.7% with high serum IgG, 56.2% with elevated ESR, 50.0% with positive rheumatoid factor(RF), 43.7% with eosinophilia, 26.7% with positive antinuclear antigen(ANA),31.2% with elevated lipase, 18.7% with elevated amylase, and 25.0% with elevated CA19-9. 93.7%patients showed diffuse swelling of the pancreas on CT and/or endoscopic ultrasound. Stricture of the main pancreatic duct was seen in 100% patients. Distal common bile duct stricture was seen in 87.5%, while thickened wall of bile duct was seen in 50%. Histological findings of the pancreas EUS-FNA showed nonspecific results in one patient, while no tumor cell was detected in other 5 patients; lymphocytes infiltration was noted in 3 patients; pancreatic fibrosis was seen in 2 patients. 75.0% patients was found to have diabetes or abnormal sugar tolerance, enlargement of the celiac lymph nodes in 43.7%, splenic vein or inferior cava vein involvement in 42.9%, swelling of the maxillary glands in 18.7%, the lacrimal glands in 12%. Prednisone was given to 11 patients, among them 5 patients underwent endoscopic stent placement, and 10 patients responded well while 1 patient discontinued therapy due to intolerance. 2 patients underwent endoscopic stent placement alone and jaundice disappeared. 3 patients received conventional medical treatment. Steroid therapy exerted different effects on levels of the blood glucose, the enlarged maxillary and lacrimal glands improved after steroid therapy. Conclusions AIP occurred in middle aged and senior male predominantly, painless obstructive jaundice was the main clinical presentation, and patients may be accompanied with elevated levels of IgG, hypergammaglobulin, positive RF and ANA, diffuse or focal pancreatic enlargement, pancreatic duct stricture and distal common bile duct stricture. Stent placement could improve the symptoms, and steroid therapy was effective.
ABSTRACT
@#Objective To determine the utility of computed tomographic (CT) enteroclysis for characterization of the status of the anastomotic site in patients with Crohn's disease (CD) who have previously undergone ileocolic resection. Methods Totally 31 CD patients who had previously undergone ileocolic resection were enrolled in the study. After having been orally administered with isosmotic mannitol, the patients received CT scanning including plain scan, arterial phase scan, and portal venous phase scan. The abnormal CT findings were analyzed based on portal venous phase images. CT enteroclysis findings in 31 patients were evaluated by two radiologists in consensus. Endoscopic findings, histopathologic findings, and/or the Crohn's disease activity index (CDAI) were used as the reference criteria. Associations between CT enteroclysis findings and anastomotic site status were assessed. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of CT enteroclysis for the diagnosis of normal anastomosis versus anastomotic recurrence were estimated. Results Twenty-six cases and 5 cases were diagnosed as disease recurrence and normal anastomosis, respectively. In the disease recurrence group, 11 patients (42%) had lymphadenopathy (diameter＞ 1 cm) and 8 patients (31%) had peri-anastomotic fistulas, which were absent in normal anastomosis group, but the difference was not significant Anastomotic wall thickening more than 6 mm, marked mucosal enhancement, stratification, and peri-anastomotic stranding were found in 16 (62%), 19 (73%), 14 (54%), and 20 (77%) cases, respectively, in disease recurrence group, which were absent in normal anastomosis group ( all P ＜ 0.05 ). When the diagnosis of anastomotic recurrence was based on more than two of the following six variables, including lymphadenopathy, peri-anastomotic fistulas, anastomotic wall thickening more than 6 mm, marked mucosal enhancement, stratification, and peri-anastomotic stranding, its sensitivity, specificity, postive predictive value, negative predictive value, and accuracy yielded 88%, 100%, 100%, 63%, and 90%, respectively. The diagnostic accuracy of anostomotic stenosis with CT was only 53%. Conclusion CT enteroclysis yields objective and relatively specific morphologic criteria that help differentiate between recurrent disease and normal at the anastomotic site after ileocolic resection for CD.
ABSTRACT
Objective To find the features and diagnostic values of CT for adrenal ganglioneuroma.Methods CT examinations were performed in 16 cases(7 with plain scan and 9 with both plain and enhanced scan).All cases were confirmed by pathological evidence.Results 2 cases showed solid -cystic mass,14 were solid mass,and 5 accompanied with calcification.The average CT value was from 20 to 40 HU.In 9 cases with enhanced scan,5 slightly enhanced on delayed phase and no enhancement was seen in the others.Conclusion Adrenal ganglioneuroma showed some characteristic CT appearance and CT scanning plays an important role in diagnosis of adrenal ganglioneuroma.
ABSTRACT
Objective To investigate the diagnostic value of capsule endoscopy (CE), CT enterography (CTE), ileocolonoscopy and small bowel follow through (SBFT) for small bowel Crohn's disease (CD). Methods Fifty-seven consecutive patients with CD underwent ileocolonoscopy, CTE, CE, and SBFT. It included the presence of the following symptoms and signs: abdominal pain, weight loss,diarrhea, fever and positive fecal occult blood test. The location and the characteristics of intestinal and extra-intestinal lesions detected by four techniquks were compared. The proportions of patients with positive findings using each examination were compared. Results Of the 57 patients, 50 underwent ileocolonoscopy, terminal ileum lesion was found in 33 patients (66. 00% ), the remaining 17 (34.0%)were normal; among 34 patients who had CTE, 29 of small bowel lesion were found (85. 29% ); CE were performed in 27 patients, due to prolonged gastric transit one time, the capsule did not reach the cecum in one patient during battery lifetime. CE showed small bowel lesion in 26 patients (96.30% ); SBF was performed in 39 patients and 26 of small bowel lesion were detected (66. 67% ). CE had the highest diagnostic yield for CD and ileocolonoscopy had the lowest, and there were statistically significant difference among the 4 examinations (P = 0. 006 ). The combinded positive rates of two methods were: CE + CTE 92. 86% (13/14), SBFT + CTE 90. 91% (20/22), CE + ileocolonoscopy 95. 65% (22/23), CE + SBFT100% (17/17), ileocolonoscopy + CTE 89. 66% ( 26/29 ), ileocolonoscopy + SBFT 77.78% ( 28/36 ), but there were no significant differences between each two examinations. Conclusion CE, CTE have a higher yield in depicting mild to moderate finding of CD than SBFT. CE is better for assessing early mucosal disease,whereas CTE is better for detecting transmural and extraluminal abnormalities. Most important, CE plus CTE may depict nonobstructive CD of the small bowel when conventional techniques such as ileocolonoscopy or SBFF have negative or inconclusive finding. CE provides us explanations for the symptoms of patients, decision to follow up or therapy.
ABSTRACT
<p><b>OBJECTIVE</b>To identify the optimal dosage of 17beta-estradiol gel + oral progestin for preventing bone loss in postmenopausal Chinese women.</p><p><b>METHODS</b>A 3-year open label, randomized, prospective clinical trial was conducted. Sixty healthy women who had been postmenopausal for 1 to 5 years were recruited and divided into following 4 groups: group 1, percutaneous gel 17beta-estradiol (E(2)) 1.5 mg/d plus micronized progesterone (MP) 100 mg/d; group 2, percutaneous gel 17beta-estradiol (E(2)) 1.5 mg/d plus medroxyprogesterone acetate (MPA) 2 mg/d; group 3, percutaneous gel 17beta-estradiol (E(2)) 0.75 mg/d plus micronized progesterone (MP) 100 mg/d; and group 4, percutaneous gel 17beta-estradiol (E(2)) 0.75 mg/d plus medroxyprogesterone acetate (MPA) 2 mg/d. Estrogen and progestin were given continuously for 25 days per month. Bone mineral density (BMD) was measured using quantitative computed tomography (QCT) for trabecular bone of L2-5 and dual energy X-ray absorptiometry (DEXA) for L2-4 and hip 5 times during the trial at baseline and at the 6-, 12-, 18-, 24- and 36-month visits.</p><p><b>RESULTS</b>Fifty-nine patients (98.3%, 59/60) stayed in the study for 1 year, 56 patients (93.3%, 56/60) for 2 years, and 51 (85%, 51/50) for 3 years. On average, menopausal symptoms were relieved by 80% after 6 months of treatment. By the 24th month, the mean increase in BMD ranged from 4.3% to 7.5% in trabecular bone; and by the 36th month, it ranged from 4.2% to 6.2% in L2-4 and 1.61% to 3.77% in the neck. There were significant difference after treatment (P < 0.05). Among the four groups, no significant difference (P > 0.05) was found in improvement of symptoms, levels of bone markers or BMD.</p><p><b>CONCLUSION</b>A daily dose of estradiol gel, either 0.75 mg or 1.5 mg, is effective in preventing early postmenopausal bone loss and relieving menopausal symptoms. After 3-year treatment, spinal BMD could increase steadily, so does hip BMD, especially in the first 2 years.</p>

Objective To analyze the clinical and radiological features of retroperitoneal fibrosis (RPF), and to deepen the understanding of this unusual disease and improve the diagnostic level at the early stage. Methods Fourteen cases (10 males and 4 females, mean age 45.8 years) of pathologically diagnosed RPF from January 1990 to June 2004 were summarized. The clinical and radiological performance of the cases were analyzed. All patients received non-contrast CT scanning, 10 of them underwent enhanced CT scanning as well. 8 patients received MRI, 10 patients received IVP examination, and 11 received B-ultrasound. Results (1)The very first symptoms usually included back pain, bellyache (10 cases), or urinary tract obstruction (3 cases), with increase of ESR, IgG, CRP value and abnormal renal function.(2)The result of radiological examination showed that 11 lesions of the 14 cases located at retroperitoneum. Ten cases were mass type and 4 cases were diffuse type. Non-contrast CT scanning revealed soft tissue mass at retroperitoneum with inhomogenous or homogenous density. After contrast medium injection the lesions were enhanced with different extent. MRI results showed that the lesions presented low signal in T_1WI, while in T_2WI the signals had no obvious coherence but were different from one case to another. Conclusion Radiological examination is one of the important methods for diagnosis of RPF. Based on the different characteristics of RPF in CT and MRI, together with the clinical findings, we will get valuable references for staging and follow-up of RPF.
ABSTRACT
Objective To understand the clinical characters and imaging features of Mirizzi syndrome.Methods All 15 patients were confirmed by operation , including 10 females and 5 males , aged 41～82 (mean age 65.1 years old). The course ranged from 4 days to 15 years. Among them, ERCP were performed in 8 patients, PTC in 2 patients, MRCP in 4 patients and CT in 3 patients.Results Cholangiography of Mirizzi syndrome revealed a broad, curvilinear impression on the common hepatic duct in the area where the cystic duct or gallbladder was in direct apposition, hepatic bile duct dilation above the level of the cystic duct. 6 cases were diagnosed to be Mirizzi syndrome preoperatively (3 cases in ERCP , 2 cases in PTC , 1 case in MRCP), 7 cases bile duct stone, 1 case bile duct dilation, 1 case normal. Conclusion Mirizzi syndrome is a rare disease . No pathognomonic features appear in either the history or the physical examination .Diagnosis requires a combination of ultrasonography , cholangiography (ERCP,PTC), CT and MRI .
