Study on Improvement Effects of Rouganbao Granules on Related Index of Liver Fibrosis Model Rats / 中国药房

OBJECTIVE:To study the improvement effects of Rouganbao granules on liver fibrosis of model rats,and to provide experimental evidence for further development of this preparation. METHODS:Totally 45 male SD rats were divided into normal group,model group,positive control group(Fuzheng huayu capsules,0.4 g/kg)and Rouganbao granules high-dose and low-dose groups(16.8,8.4 g/kg by crude drug)according to random number table,with 9 rats in each group. Except for normal group,other groups were given CCl4sub cutaneously and high lipid diet+15% ethanol solution for 12 weeks to establish liver fibrosis model. After modeling,medication groups were given relevant medicine intragastrically,once a day,for consecutive 12 weeks. Normal group and model group were given corresponding volume of water intragastrically. The pathology change of liver tissues of rats was observed by inverted microscope. The levels of liver function indexes (ALT,AST,ALB) and liver fibrosis indexes(HA,Ⅳ-C,LN,Ⅲ-PC)were determined by ELISA. RESULTS:Compared with model group,liver cell vacuolation and liver fibrosis of rats were improved significantly in Rouganbao granule high-dose and low-dose groups;central vein was clearly visible,and no dilation and atrophy were found,especially in high-dose group;the serum levels of ALT and AST were decreased significantly,while the level of ALB was increased significantly(P＜0.05 or P＜0.01),of which the protective effect for liver was similar to positive control drug but better in increasing ALB(P＜0.05 or P＜0.01);the serum levels of HA,Ⅳ-C,LN and Ⅲ-PC were all decreased in varying degree,especially in high-dose group(P＜0.05 or P＜0.01),of which the effect of relieving liver fibrosis was similar to positive control drug. CONCLUSIONS:Rouganbao granules can improve liver function and delay the progression of liver fibrosis in model rats.

A relationship between the brain magnetic resonance imaging of optic nerve myelitis patients and their CSF biochemical indexes / 中国基层医药

Objective To compare differences of CSF biochemical index in optic myelitis combined with abnormal signal in craniocerebral MRI with no significant abnormalities in brain MRI.Methods The data of 39 cases who meet the diagnostic criteria of Wingerchuck were collected.The brain MRI and cerebrospinal fluid,blood bio-chemical indexes were retrospectively analyzed.Results There were no statistical differences between two groups of patients in onset age,average age,hospitalization days,the number of red blood cells,white blood cell,hemoglobin, cerebrospinal fluid leukocyte and CSF synthetic index,the total number of cells,cerebrospinal fluid IgG,synthetic rate index of sheath,but the index of blood brain barrier(CSF:serum albumin ratio,AR)of NMO patients with craniocere-bral MRI abnormalities was higher than normal group(P <0.05).Conclusion NMO patients with brain abnormali-ties are common,and cerebral MRI with signs of abnormalities shows a higher AR value,speculated that abnormal brain MRI signal in NMO patients is associated with the damage of blood -brain barrier,investigation of NMO brain MRI performance can improve the diagnosis of the NMO and identification with multiple sclerosis.

Early stage postoperative complications of laparoscopic radical cystectomy / 中华泌尿外科杂志

Objective To investigate feasibility and early stage postoperative complications of lapa-roscopic radical cystectomy ( LRC) . Methods We retrospectively analyzed the data of 63 consecutive pa-tents (58 males and 5 females) who underwent LRC from Oct .2011 to Oct.2013 in our institute.Of these patients, 46 patients underwent ileal conduit , 9 patients underwent ureterocutaneostomy , and 8 patients un-derwent orthotopic ileal neobladder urinary diversion .The average age and body mass index of patients were 67.7±11.1 (33-84) years and 23.3±2.1 (18.8-28.7) kg/m2, respectively.The mean hemoglobin and al-bumin of patients were (130.7±20.3) g/L and (38.9±4.1) g/L, respectively.Comorbidities of hyperten-sion, diabetes, coronary heart disease and decompensated liver cirrhosis were found in 10, 6, 2 and 1 pa-tient, respectively.10 of 61 patients had a history of abdominal surgery .The indications for cystectomy were classified as muscle invasive bladder cancer for 30 patients, unresectable superficial bladder cancer for 19 patients and recurrent bladder cancer for 14 patients.Postoperative data and early stage postoperative compli-cations within 3 months after surgery were collected . Results The median operative time for LRC and uri-nary diversion was 390 (260-480) min, with a median estimated blood loss of 400 (100-1 500) ml.This was one patient converted to open surgery .The mean postoperative hemoglobin and albumin of patients was 108.5±14.7 g/L and 29.5±3.7 g/L, respectively, both of which significantly reduced compared with pre-operative data (P<0.01).The median duration of hospital stay was 15 days.The median time for liquid in-take, abdominal drainage removal and ureteral stent removal was 4 days, 9 days and 2 months after surgery , respectively.Catheter was removed 2 weeks after laparoscopic orthotopic cystectomy .21 (33.3%) of 63 pa-tients suffered from perioperative complications .15 of 46 patients (32.6%) in ileal conduit group had com-plications including ileus ( 5, 1 of 5 need re-operation ) , lymphatic fistulas ( 5) , pulmonary infection ( 1) , pyelonephritis (1), delirium (1), anastomotic leak (1, re-operation was needed) and pneumothorax (1). 2 of 9 patients (22.2%) in ureterocutaneostomy group had complications such as ileus (1) and lymphatic fistulas (1).4 of 8 patients (50.0%) in orthotopic ileal neobladder group suffered from complications like ileus (2, 1 of 2 required re-operation), lymphatic fistulas (1) and arrhythmia (1). Conclusions LRC is technically feasible and safe .It reduces the estimated blood loss and postoperative complications .It is noteworthy to surgeons that serum albumin significantly reduced after LRC , nutrition should be kept balanced after surgery.

Clinical study of external beam radiotherapy combined with californiam-252 neutron after loading intracavitary radiotherapy in the treatment of patients With T1 and T2 nasopharyngcal carcinoma / 肿瘤研究与临床

Objective The results and side effects of nasopharyngeal carcinoma treated by combined external radiotherapy and Californium -252 neutron after loading intracavitary radiotherapy. Methods From November 2005 to March 2007, 30 nasopharyngeal carcinoma patients with staged T1 and T2 by 1992 Fuzhou staging system, were treated by external beam radiotherapy combined with Californium-252 neutron after loading intraeavitary radiotherapy. Results All patients were followed up for 2 years. 2 cases recurred in the nasopharynx. 4 cases developed distant metastases. 2 cases developed trismus. No perforations in hand and soft palate occurred. Conclusion External beam radiotherapy combined with Californian-252 neutron after loading intracavitary radiotherapy for nasopharyngeal carcinoma is indicated for boosting the dose to the nasopharyngeal cavity; reducing the dose for external irradiation. It can improve local control rate of nasopharyngeal carcinoma and reduce occur rate for the trismus.
