China Pharmacy 1991;0(02):-
OBJECTIVE:To analyze the factors in the causation of cefradine-induced hematuria.METHODS:The material in CHINESE BIBLIOGRAPHIC DATA BASE OF BIOLOGY & MEDICINE(from 1980 to February 2001)and PHARMACEUTICAL ABSTRACTS(1990~2000)was reviewed and the data were analysed on patients'age and sex,route of drug administration,beginning of hematuria,prognosis and time of recovery.RESULTS:18 reports on cefradine-induced hematuria(108 cases) were found,which indicated that hematuria was mainly associated with renal hypoplasia in childhood and intravenous administration of cefradine.CONCLUSION:Intravenous administration of cefradine in children should be very careful.

Purpose:To study the pathological and clinical characteristics of different subtypes of cyst-associated renal cell carcinoma and summarize the experience in diagnosis and therapy. Methods:39 cases with cyst-associated renal cell carcinoma underwent urological operations in our hospital from 1991 to 2000. Their medical data were analyzed and then divided into different subtype according to pathological characteristics. Results:The data included 2 patients with renal cell carcinoma on the background of polycystic kidney, 20 cases with renal cell carcinoma originating in a cyst and 17 cases with cystic renal cell carcinoma.3 patients underwent partial nephrectomy and 36 cases unilateral radical nephrectomy.16 patients were Robson stage Ⅰ and 23 were RobsonⅡstage.The pathological diagnosis was 38 cases of clear cell carcinoma and one of chromophobe cell carcinoma. The survival rates at 1,3,5 years are 100%、100%、94.8%(37/39) respectively after follow-up. Conclusions:The cases with renal cyst need periodical health check-up.Most of cyst-associated renal cell carcinomas belong to low stages. Contrast-enhanced computed tomography and selective digital subtraction angiography of renal artery are the main methods for preoperative clinical diagnosis. The long-term effect of operations of cyst-associated renal cell carcinoma is better.

Objective To study the dynamic changes of serum concentration of soluble cell adhesion molecule (sCAM) in patients with aneurysmal subarachnoid hemorrhage.Methods Serum concentrations of sCAM in 30 patients with aneurysmal subarachnoid hemorrhage were detected using ELISA method before surgery and at 1~3 d, 7~9 d and 11~13 d after surgery. Transcranial Doppler sonography was used to measure the velocity of middle cerebral artery (VMCA). The results were compared with 20 healthy controls.Results Serum concentrations of sCAM at 1~3 d and 7~9 d in patient group were significantly higher than that in control group (all P

6 cm AVMs(57.1%)were much higher than that with 0.05).Seizure was found in forty-three patients.After embolization the seizure in 20 patients disappeared,11 patients had been improved greatly.The total effective power was 72.1%.Conclusions The size and location of AVM is significantly associated with the onset of seizure.The number of feeding artery has no relation with the seizure.Endovascular embolization for the AVMs has got better cure effect.

Objective To study the effects of treating intracranial hypertension(ICP) with different dosage Mannitol alone or combined with Furosemide.Methods 60 patients with high ICP after all kinds of operations on cranium and brain were divided into 4 groups according to the dosage of Mannitol alone or combined with Furosemide: 0.5 g/kg Mannitol(group A),1.0 g/kg Mannitol(group B),0.5 g/kg Mannitol and 20 mg Furosemide(group C),1.0 g/kg Mannitol and 20 mg Furosemide(group D).The effective power,rebound ratio,average effective time,average amplitude of decreasing ICP,plasma osmolarity and renal function were evaluated by monitoring intracranial pressure.Results In response of the effective power,rebound ratio of ICP and average effective time,groups C and D were more noticeable than groups A and B(all(P

Crude extract of Periplaneta americana was prepared by liquid nitrogen grinding.After being purified with DEAE Sephadex A-50 ion exchange chromatography,the protein content of the extract was determined and the extract solution was prepared at gradient concentrations.The crude extract and purified allergen at different concentrations were dotted respectively on nitrocellulose(NC) membrane.Patient serum,bio-IgE,sa-HRP,luminal regents were added to the membrane.The chemiluminescence was displayed by exposing to X-film.The result revealed that the minimum protein content of crude Periplaneta americana extract detected by CLIA is 0.87?g/ml,with 90% accordance to skin test positive patients,and 100% accordance to those with negative skin test and ELISA detection.

Objective To study the preventive effect of recombinant streptokinase (r-SK) on cerebral vasospasm (CVS) after subarachnoid hemorrhage(SAH).Methods Rabbit models of SAH were made by double blood injection into cisterna magna. A tube was inserted into lateral ventricle after 24 h. In group treating one, 1.25 mg r-SK were injected into lateral ventricle, and the tube was opened for drainage after closed 6 h, and then 6 h later, injection, closed pipe and drainage were recycled for another 2 times. In the group SAH , 1 ml normal saline (NS) was injected into lateral ventricle, and then the way was the same as group treating one. In group treating two, 3.75 mg r-SK were injected for once. 6 h, 12 h ,1 d, 3 d, 5 d and 7 d later, 1 ml CSF was drained from the lateral ventricle in groups SAH , treating one and treating two ,respectively. The level of OxyHb in CSF was detected, angiograms of basilar artery(BA) were performed before and after 7 d of SAH,calculation the rate of calibre and histological examinations were also performed. Results (1)The level of OxyHb in CSF of group SAH was increased gradually while decreased in groups treating one and treating two. Compared with group SAH, the levels of OxyHb were significant lower in groups treating one and treating two at 1~7 d after administration(P

Objective To study the initial experience and outcomes of laparoscopic enucleation with preoperative selective arterial embolization ( PSAE) for the treatment of renal angiomyolipomas. Methods A total of 43 patients with sporadic renal angiomyolipomas from July 2013 to November 2014 underwent laparoscopic nephron-sparing surgery ( NSS) .The patients were divided into either PSAE group ( n =19 ) or non-PSAE group ( n =24 ) .The data of patient demographics, success rate of surgery, perioperative complications rate, operating time ( OT ) , warm ischemia time ( WIT ) , estimated blood loss ( EBL ) , length of hospitalization, kidney estimated glomerular filtration rate (eGFR) and serum creatinine (Scr) level over 3 months, and ipsilateral recurrence were collected and compared between the two groups. Results Enucleation was successful in 100%patients (19/19) of the PSAE group and in 62.5%patients (15/24) of the non-PSAE group,with no significant difference ( Fisher' s test, P=0.105) The EBL was (46.4 ±20.6) ml in the PSAE group, which was significantly less than the non-PSAE group [(89.5 ±30.4) ml, t=-5.287, P=0.000].The OT and WIT were significantly shorter in the PSAE group than those in the non-PSAE group [(90.3 ± 21.1) min vs.(131.7 ±18.6) min, t=-6.831,P=0.000;(9.5 ±5.7) min vs.(24.2 ±4.8) min, t=-9.181, P=0.000]. The length of hospitalization was significantly longer in the PSAE group than that in the non-PSAE group [(7.7 ±1.1) d vs.(6.3 ± 1.3) d, t=3.748, P=0.000].No severe complications occurred in the PSAE group, whereas the non-PSAE group had 1 case of urinary leakage and 1 case of hematoma.The Scr level over 3 months after surgery was more ideal in the PSAE group [(70.1 ±13.7)μmol/L vs.(84.2 ±9.1) μmol/L, t=-4.045, P=0.000].No statistically significant difference was found in the eGFR between the PSAE group and the non-PSAE group [(72.6 ±12.8) ml· min-1· 1.73 m-2 vs.(68.0 ±10.7) ml· min-1· 1.73 m-2, t=1.284, P=0.206].No evidence of recurrence was found during follow-up period in both groups. Conclusions Laparoscopic enucleation with PSAE is a safe and effective minimally invasive procedure for the treatment of renal angiomyolipomas.As compared to traditional laparoscopic partial nephrectomy, it has advantages of less WIT, less EBL, and better protection of renal functions.It can be recommended in well-selected patients.
