OBJECTIVE:To establish fingerprint of Zhizi jinhua pills(ZZJHW)and analyze the relationship of it with in vitro antioxidant activity,in order to provide the basis for the quality control of them. METHODS:HPLC method was adopted. The sep-aration was performed on a Sinochrom ODS-BP C18(200 mm×4.6 mm,5 μm)column with mobile phase consisted of 0.2% acetic acid(containing 3 mmol/L sodium heptanesulfonate solution)-acetonitrile(gradient elution)at the detection wavelength of 254 nm and flow rate of 0.8 ml/min. The column temperature was controlled at 38 ℃,and injection volume was 10 μl. The“Chromato-graphic Fingerprint Similarity Evaluation System for TCM”(2012.130723 edition) issued by Chinese Pharmacopoeia Commission was used to evaluate the similarity of the 12 batches of ZZJHW using baicalin as reference peak so as to attribute the common peak of fingerprint. DPPH free radical scavenging assay was used to investigate the in vitro antioxidant activity of 12 batches of ZZJHW,and the relationship between its fingerprint and antioxidant activity was studied. RESULTS:The fingerprint of 12 batches of ZZJHW was established and the similarity between the fingerprint of ZZJHW with their reference fingerprint were all above 0.9 (except S1,S2,S3,S12). 30 common peaks were marked,all of which were assigned to the herbs. Antioxidant experiment result showed the differences in the antioxidant capacity among different batches of ZZJHW;spectrum effect relationship showed that 13 common peaks were positively related with oxidation activity and 17 common peaks negatively related with it;among known com-ponents,oxidation activity components were mainly from Lonicera japonica,Scutellaria baicalensis and Rheum palmatum. CON-CLUSIONS:The spectrum effect relationship of established fingerprint with its antioxidant activity can provide reference for the quality control of ZZJHW.

BACKGROUND: Renin-angiotensin-aldosterone system existed in bone tissue. Recent studies on antihypertensive drugs found that angiotensin converting enzyme inhibitor type antihypertensive drug was possibly effective for osteoporosis. Perindopril is one of the commonly used antihypertensive drugs. Whether perindopril affected bone metabolism or could be used in anti-osteoporosis has not been reported.
OBJECTIVE: To observe effects of perindopril on bone metabolism in a rat model of osteoporosis induced by retinoic acid.
METHODS: Fifty Sprague-Dawley rats were randomly divided into five groups, with ten in each group. In the model group and each perindopril groups, rats were intragastricaly administered retinoic acid solution 80 mg/kg per day. After successful model establishment, rats in different perindopril groups were intragastrical y administered perindopril 2, 4 and 8 mg/kg per day, once a day, for 42 consecutive days. In the normal control and model groups, rats were given an equal volume of distil ed water. Serum calcium, phosphorus, alkaline phosphatase, bone mass and bone mineral density were detected in each group. Expression of bone specific alkaline phosphatase and tartrate-resistant acid phosphatase mRNA in bone tissue was determined.
RESULTS AND CONCLUSION: Compared with the model group, after treatment with perindopril, serum calcium and phosphorus levels were increased, alkaline phosphatase activities were significantly decreased, bone mass and bone mineral density were obviously increased in rats with retinoic acid-induced osteoporosis. Expression of bone specific alkaline phosphatase mRNA was higher in the perindopril 8 mg/kg group than in the perindopril 2 and 4 mg/kg groups and model group. Tartrate-resistant acid phosphatase mRNA expression was higher in the perindopril 8 mg/kg group than in the model group. These results indicated that perindopril could improve partial bone metabolic biochemical markers in osteoporosis rats, promoted bone formation by up-regulating bone specific alkaline phosphatase mRNA expression, and had a certain preventive effect on retinoic acid-induced osteoporosis.

Objective To investigate the efficacy and safety of ultra-mini percutaneous nephrolithotomy for the treatment of renal or upper ureteral stones.Methods The data of 32 patients diagnosed as renal or upper ureteral stones were retrospectively reviewed,who underwent ultra-mini percutaneous nephrolithotomy from June to October,2015,including 29 kidney stones,3 upper ureteral stones,of which 21 single stone,7 multiple stones,and 4 staghorn stones.There were 8 cases with inferior calyx stones,10 with renal pelvis stones,3 with upper ureteral stones,10 with renal pelvis stones plus inferior calyx stones and 1 with renal pelvis stones plus upper calyx stones.The mean stone size was (20.1 ±7.6) mm (ranging from 10 to 41mm).The mean Hounsfield unit (HU) was (1 125.9 ±225.9) Hu (ranging from 520 to 1 550Hu).In this cohort,13 cases had mild hydronephrosis,2 moderate hydronephrosis,1 severe hydronephrosis while no hydronephrosis identified in the other 16 patients.One case had concomitant kidney and ureter duplication malformation,and 1 case had residual stones after laparoscopic nephrolithotomy.Results All of the patients were treated by single tract UMP.Among them,middle calyceal puncture was performed in 9 cases,and the other 23 cases underwent lower calyceal puncture,including 4 cases of intercostal puncture,and 28 subcostal puncture.The mean operating time was (30.3 ± 15.0) min (ranging from 10 to 90 min).The mean postoperative hospital stay was (1.9 ± 1.0)days (ranging from 1 to 5 days).The mean hemoglobin decrease was(14.6 ±8.4)g/L (ranging from 1 to 46 g/L).No analgesics were used.Peri-operative complication rate was 3.13％ (1/32) with 1 case of collection system perforation.There was no fever,severe bleeding,urinary extravasation,pleural injury,or blood transfusion.The SFR was 93.75％ (30/32) and 96.88％ (31/32) on the first day and the first month after the operation,respectively.Conclusions UMP could be a safe and effective method for the treatment of renal or upper ureteral stones,especially for inferior calyceal stones less than 2cm.It offers high stone clearance rate,minimally invasiveness,quick recovery,short length of hospital stay and improved quality of life.

Objective To improve the understanding of cutaneous intravascular natural killer/T-cell lymphoma (CIVNKTC). Methods Clinical data on five cases of CIVNKTC were collected. The histopathological feature, treatment and prognosis of CIVNKTC were retrospectively analyzed and discussed. Results Of the 5 patients, 1 was male and 4 were female. The age of onset ranged from 38 to 83 years (average, 56.2 years). All the patients presented with multiple plaques and nodules as the primary symptoms. Histopathological examination revealed vasodilatation in the dermis and subcutaneous tissue, as well as atypical lymphoid cells with large hyperchromatic nuclei containing 1-2 small nucleoli in dilated veins. Immunohistochemical studies of tumor cells showed positive staining for CD3ε, cytotoxic proteins (including T cell-restricted intracellular antigen-1, granzyme B and perforin)and Epstein-Barr virus(EBV)-encoded microRNA, but negative staining for cytokeratin, CD20, CD79a, CD4 and CD8. Furthermore, the tumor cells stained positive for CD56 in two patients. Among the 5 patients, only 2 received chemotherapy and the remaining received no treatment. During a 24-month follow-up, 4 patients died, and only 1 survived with the tumor. Conclusion CIVNKTC is a rare extranodal Hodgkin′s lymphoma with distinct histologic manifestations and immunophenotypes, rapid and aggressive clinical course, and poor prognosis.

Objectives To study the value of CT and MRI in diagnosing focal nodular hyperplasia (FNH).Methods The CT and MRI findings of 16 patients with FNH confirmed histopathologically were analyzed retrospectively.Both plain and dynamic enhanced CT scannings were performed in all the patients.Plain and dynamic enhanced MRI were carried out in 9 patients.Results (1) There were 16 patients with 19 lesions,and 8 lesions were in the left lobe,5 lesions in the right lobe,4 lesions between the left/right lobes and 2 lesions in the caudate lobe.The morphology of the lesions showed 15 lesions to have clear boundaries and 4 lesions to have fuzzy boundaries.The tumor diameters varied from 2.2 to 9.6 cm,(average 4.3 cm).(2) Sixteen patients underwent CT examination.On plain CT,the lesions were isotonic (n＝ 5),or slightly low-density (n=11).In 7 lesions,there was a slit-like,stellate-shaped low density central scar.Nine patients underwent MRI examination.On T2WI,6 lesions showed slightly higher signal while the remaining 3 lesions showed iso-signal.On T1WI,4 lesions showed slightly lower signal,3 lesions showed iso-signal and 2 lesions showed slightly higher signal while in 1 lesion the local signal showed reduction in anti-phase 1.A central scar was seen in 6 lesions which showed high signal on T2WI,and low signal on T1WI.(3) Enhanced CT: 15 lesions were significantly enhanced and 1 lesion showed mild enhancement at the arterial phase.For the patients with mild enhancement,the scar in the center of the lesion showed no enhancement.In all lesions,the central scar did not enhance.In 5 lesions,enhancements of thickened and torturous arteries were seen.In all the lesions with enhancement,the enhancement was reduced at the portal venous phase,with 12 lesions showing slightly higher density,3 lesions isodensity and 1 lesion low-density.Three lesions showed mild enhancement of the central scar.All the substantial parts of the lesions with enhancement declined at the delay phase,with 3 lesions showing slightly higher density,9 lesions of isodensity and 4 lesions slightly low density.In 7 lesions with central scar delayed enhancement,they showed slightly higher density.Nine patients underwent MRI enhancement and the enhancement characteristics were similar to CT,but the arterial phase magnitude was higher than that of CT.In 4 lesions,the central scar began to enhance at the portal venous phase,while 6 lesions continued to enhance,thus showing slightly higher signal at the delay phase.In a large lesion,there was persistent delayed enhancement in the capsule.(4) On DWI,6 lesions showed inhomogeneous,slightly hyperintensity with the center showing a slit-like low signal area.Three lesions showed iso-signal.The ADC values of the lesions were (1.31±0.08)× 10-3 mm2/s,and the normal liver parenchyma were (1.22± 0.14)× 10-3 mm2/s,(difference not statistically significant).Conclusions CT and MRI using plain and dynamic enhanced scans could show fully and accurately the pathological features and the characteristics of blood supply of FNH.The characteristic signs on both CT and MRI make an accurate diagnosis of FNH.MRI when compared with CT was slightly better.A combined use of both CT and MRI has an important value in the diagnosis of FNH.
