OBJECTIVE:To establish the method for simultaneous determination of 9 common inorganic anions in Huanglian shangqing tablet. METHODS:The accelerated solvent extraction-ion chromatography was adopted. Inorganic anions were deter-mined by Ion Pac AS11-HC anion exchange column,protected by Ion Pac AG11-HC column and eluted by hydroxide potassium so-lution(gradient elution)at the flow rate of 1.2 mL/min. The column temperature was set at 30 ℃,elution time was 18 min,and sample volume was 25 mL. RESULTS:The linear ranges of fluorinion,formate ion,nitrite ion,bromide ion,nitrate ion,sulfate ion,oxalate ion and phosphate ion were 0.1-5 mg/L(r=0.9990-0.9999). The limits of quantitation were 0.020,0.078,0.030, 0.058,0.052,0.068,0.084,0.064,0.074 mg/L,and the limits of detection were 0.005,0.024,0.008,0.017,0.015,0.022, 0.026,0.020,0.021 mg/L,respectively. RSDs of precision,stability and repeatability were all lower than 4.0%;recoveries were 80.00%-125.08%(RSD ranged 0.97%-2.47%). CONCLUSIONS:The method is simple,precise,stable and repeatable,and can be used for 9 common inorganic anions in Huanglian shangqing tablet.

Objective To analyze the clinicaopathological features and treatment of bilateral asynchronous breast cancer.Methods The clinical and pathological data of 13 patients with bilateral asynchronous breast cancer admitted in our hospital from 2010 to 2016 ere retrospectively reviewed.Results The bilateral asynchronous breast cancer accounted for 1.7% of all breast cancer patients admitted n the same period (13/782).The median age of patients at first onset was 47.The modified radical operation was the main surgical lity (12/13 for the first cancer;8/13 for the second cancer).The clinical stage Ⅱ was predominant in all patients (10/13 of the first r;9/13 of the second cancer).Invasive ductal cancer was the most common pathologic type (in 11/13 of the first cancer;11/13 of the cond cancer).Hormone receptors were highly expressed in most of the cases (9/13 of the first cancer;7/13 of the second cancer).The disease-free interval was more than 10 years in most cases (8/13).Among 13 cases local recurrence was detected in 1 case, distant metastases in 2 cases, and 1 case died from distant metastasis.Conclusion The bilateral asynchronous breast cancer has a low incidence;however, a close follow up is necessary for early detection and treatment of the second carcinoma.

Objective To investigate the mechanism of pulmonary fibrosis induced by paraquat (PQ),and the effect of Xuebijing injection in treatment of PQ poisoning.Methods Seventy-two male Wistar rats were randomly divided into control group,PQ poisoning group,and Xuebijing intervention group,with 24 rats in each group.Pulmonary fibrosis was induced by single garage at the dosage of 50 mg/kg of PQ,while 1 mL of distilled water was given by gavage in control group.Xuebijing injection at the dosage of 4 mL/kg were given intraperitoneally at 30 minutes after exposure to PQ in Xuebijing group,and it was repeated every 12 hours; same amount of physiological saline was given intraperitoneally in PQ group and control group.The experiment lasted for 14 days.Six rats in each group were sacrificed on 1,3,7,14 days,respectively,after insult,and 30 minutes after the last intervention.The lung tissues were harvested,the changes in pathology in lung tissue and the degree of pulmonary fibrosis were observed with optical microscope with hematoxylin-eosin (HE) staining and Masson stain.The ultrastructure changes in lung tissues were observed with transmission electron microscopic,and the content of hydroxyproline (HYP) in the lung tissue was determined by alkaline hydrolysis.The expression of mitochondrial fusion protein 2 (Mfn2) was determined by Western Blot.Results ① HE staining:in PQ group,inflammation was most marked on the 3rd day.On the 7th day,exudates in the alveoli started to be organized,and hypertrophic fibroblasts were seen to secrete slim collagen fibers,and fibrosis could be seen in alveoli.On the 14th day,intensive hyperplasia of fibroblasts could be observed,and the alveolar structure was destroyed and collapsed,with deposition of collagen deposited with formation of pulmonary fibrosis.At the same time,pathologic changes were milder in Xuebijing group than those in PQ group.② Masson staining:the degree of inflammation in alveoli and pulmonary fibrosis were less marked in Xuebijing group than those of PQ group on the 14th day.③ Under the transmission electron microscopy,it was found that the mitochondria of lung tissue cells was relatively less in number on the 14th day in PQ group,and the majority of them underwent degeneration,swelling and damage.Basement membrane became folded,alvcoli were collapsed,and fibrosis was obvious.These changes were less serious in Xuebijing group.④ Content of HYP (μg/g):contents of HYP in lung tissues on the 3rd day in PQ group and Xuebijing group were significantly higher than those in control group (743.3 ± 50.2,718.1 ± 34.0 vs.665.8± 6.6,both P＜0.05),it then increased gradually,but the contents of HYP in Xuebijing group were significantly lower on the 7th day and 14th day than those in PQ group (790.5 ± 23.8 vs.876.7 ± 42.0,812.9 ± 72.3 vs.931.3 ± 33.0,both P＜0.05).⑤ Expression of Mfn2:the expression of Mfn2 in control group was relatively lower.The expression of Mfn2 in PQ group was increased gradually under stress,but its rate was low.The expression of Mfn2 (A value) in Xuebijing group was significantly higher than that in PQ group on the 1st day (0.731 ±0.035 vs.0.618 ±0.029,P＜0.05),and it was elevated steadily,reaching the peak on the 7th day (0.732 ± 0.037 vs.0.669 ± 0.034,P＜0.05),but it was lower than that of PQ group on the 14th day (0.708 ± 0.034 vs.0.765 ± 0.041,P＜0.05).Conclusions Xuebijing reduces lung inflammatory reaction and pulmonary fibrosis as a result of PQ poisoning.The mechanism is that Xnebijing regulates and increases expression of Mfn2 in lung tissue.

Objective To compare the short and long term effect of knee osteoarthritis treatment with two therapeutic methods which are simple high cut of fibula and arthroscopic lavage debridement combined with fibular osteotomy.Methods Data of 45 consecutive patients with knee osteoarthritis were retrospectively observed and selected,and then they were divided into two groups according to the operation method.23 patients with simple high cut of fibula were selected as the control group,and 22 patients with arthroscopic lavage debridement combined with fibular osteotomy were selected as the observation group.Results The VAS and AKS scores of the control group at the time of 3m,6m,1 2m were (4.1 3 ±0.76)points,(1 07.04 ±21 .53)points;(2.70 ±0.64)points,(1 41 .1 7 ±1 2.57)points;(2.43 ±0.79)points,(1 48.26 ±5.81 )points;and the scores of the observation group were (3.45 ± 0.60)points,(1 26.64 ±1 4.24)points,(2.70 ±0.73)points,(1 46.45 ±7.26)points,(2.41 ±0.85)points and (1 48.26 ±5.81 )points.The differences between the two groups were statistically significant at the time of 3 months after surgery(t =3.32,-3.62,all P <0.05),the effect of observation group was better than the control group;but the other indices had no statistically significant differences (t =0.51 ,-1 .72,0.1 1 ,-0.20,all P >0.05 ). Conclusion The simple high cut of fibula with small trauma,less cost,less surgical difficulty,and long -term clini-cal curative effect is not less than the arthroscopic lavage and debridement combined with fibular osteotomy.There-fore,it should be carried out in the primary hospitals widely.

Objective To evaluate DSA and MRI in diagnosing focal nodular hyperplasia(FNH) of the liver.Methods DSA and MRI findings in seven patients with pathologically-proved FNH were retrospectively analyzed.Selective hepatic arteriography with DSA,and both plain and dynamic contrastenhanced MR scans were performed in all patients.The imaging findings were retrospectively evaluated and analyzed.Results On DSA examination,all FNH lesions were hyper-vascular,which were characterized by thickened and tortuous feeding arteries.And the feeding arteries,after entering the lesions,branched off peripherally in a radiation pattern and the lesions were evenly dyed with sharp borders.In venous phase,hepatic vein drainage was demonstrated in 6 cases.On dynamic contrast-enhanced MRI,marked enhancement of the lesions was observed,which lasted until to delayed phase when the lesions still showed hyper-intensity or iso-intensity signals.Scar signal in the lesion's center was seen in three cases,which started to enhance at portal vein phase and maintained to delayed phase.Conclusion On DSA imaging,FNH lesions are characterized by thickened and tortuous feeding arteries that branch off peripherally in a radiation pattern after entering the lesions.And the hepatic vein drainage is also a common finding in venous phase.Dynamic contrast-enhanced MRI can well display the abnormal signal of the central scar of FNH.The combination use of DSA and MRI can effectively improve the diagnostic accuracy for FNH.
