Objective To discuss the diagnosis and management of metastatic adrenal carcinoma. Methods Forty-seven cases with metastatic tumor in the adrenal glands were analyzed retrospectively from December 1996 to April 2010. Lung was the most common primary tumor site (51.1 %, 24 cases), followed by the renal cell carcinoma (12.8%, 6 cases), liver cancer (10.6%,5 cases), breast cancer (8.5%, 4 cases), melanoma (4.2%, 2 cases), and other carcinoma (12.8%,6 cases). Most patients with metastatic adrenal carcinoma had no special clinic manifestation. Lesions of 36 cases were surgically removed and 11 cases gave up operation. Results The mean survival time were 33.8±4.5 months for 31 cases underwent adrenalectomy and 6.3±2.7 months for 6 cases without operation. Patients with surgically removed adrenal metastases had better survival than those without surgical resection. Conclusions Adrenal gland is a common site of metastatic carcinoma.Ultrasonographic and CT scans are important diagnosis methods for metastatic adrenal carcinoma. Operation is still effective and long-term survival may be achieved for those well selected patients, but surgical indication must be strictly monitored.

Benign anastomotic stenosis after esophagogastrectomy could reduce the patients' quality of life,even resulting in severe malnutrition and death.The endoscopic treatment includes dilatation,stent insertion,locoregional injection,and a relatively new technique radial incision and cutting.This article reviewed the progress in endoscopic treatment of benign anastomotic stenosis after esophagogastrectomy.

BACKGROUND: Metal anchors are not easily accepted by patients as permanent foreign bodies, so bioabsorbable anchors have been gradually applied in orthopedics in recent years. OBJECTIVE: To evaluate the effectiveness of absorbable suture anchors for repairing femoroacetabular impingement syndrome combined with acetabular labral tears. METHODS: Eighty patients with femoroacetabular impingement syndrome combined with acetabular labral tears admitted in Beijing Shijitan Hospital Affiliated to Capital Medical University from February 2014 to February 2016 were selected, and all were treated by absorbable suture anchors under arthroscopy. The Harris hip score, and the Visual Analogue Scale score at baseline, postoperative 1 and 3 months were recorded and compared to assess the effectiveness. The complications and material-host reaction were recorded. The treatment satisfaction was evaluated. The study was approved by the Ethical Committee of Beijing Shijitan Hospital and all patients and their families signed the informed consents. RESULTS AND CONCLUSION: (1) The Harris hip scores at 1 and 3 years postoperatively in 80 patients with femoroacetabular impingement syndrome combined with acetabular labral tears were significantly higher than those at baseline, and the Visual Analogue Scale scores were significantly lower than those at baseline (P < 0. 05). (2) The excellent and good rate of treatment in patients at 1 and 3 years was 90. 0% and 97. 50%, respectively, and the treatment satisfaction was 87. 4% and 93. 8%, respectively. The excellent and good rate of treatment and treatment satisfaction presented an increased trend with time, but had no significant difference (P > 0. 05). (3) None appeared with anchor drop off, cartilage injury or material-host reaction. In summary, the method of absorbable suture anchors under arthroscopy has the advantages of minimal invasion, reliable fixation, simple operation, no metal implants, and significant clinical effect to treat femoroacetabular impingement syndrome combined with acetabular labral tears.

OBJECTIVETo investigate the role of exogenous carbon monoxide (CO) in protection of rat hearts from ischemia/reperfusion injury and its underlying mechanisms.

METHODSCardiac contractility, lactate dehydrogenase(LDH), creatine kinase(CK) and infarct area were analyzed by the Langendorff isolated rat hearts. All isolated hearts were subjected to 30 min of ischemia followed by 120 min of reperfusion.

RESULTSPerfusion with 25 micromol/L of CORM-2 (an exogenous CO releaser) during the first 10 min of reperfusion prevented the increase in LVEDP and decrease in LVDP, +dp/dt(max) in isolated ischemia/reperfusion hearts. CORM-2(25 micromol/L) had no effect on the changes of coronary flow, but it really inhibited the release of LDH and CK, and also reduced the infarct size. Perfusion with 10 micromol/L of CORM-2 decreased the LDH, CK and infarct size, but it did not improve the contractility of ischemia/reperfusion hearts. However, perfusion with 100 micromol/L of CORM-2 exacerbated the injury induced by ischemia/reperfusion. Pretreatment of a NOS inhibitor L-NAME and a HO-1 inhibitor ZnPP partly abolished the protection effect of CORM-2(25 micromol/L) on LVEDP, and L-NAME and a GC inhibitor methylene blue could also cancel the enhance of LVDP and +dp/dt(max) incuced by CORM-2. All of the inhibitor (methylene blue, L-NAME, a mitoK(ATP )channel blocker 5-HD and ZnPP) could partly enlarge infarct area compared with CORM-2 treatment.

CONCLUSIONSExogenous CO could protect heart from ischemia/reperfusion injury. The cardiac protection of CO might be through NOS-cGMP and HO-1 pathway, and the activation of mitoK(ATP)channel might be also involved in.

OBJECTIVETo evaluate the efficacy and prospect of Fuzheng Jianpi Recipe (FZJPR) in treating children's Spleen deficiency anorexia (CSDA) by means of observing its effect on trace element content and immune function.

METHODSOne hundred and thirty cases of CSDA were treated with FZJPR, one dose per day in decoction, orally taken, 30 days for one therapeutic course. Levels of T-lymphocyte subsets, IL-2R, immunoglobulin and trace elements were determined before and after treatment, and compared with those in the control group consisted of 60 healthy children.

RESULTSIn the treated group, abnormal figures were shown in T-lymphocyte subsets, especially in lowering of CD3 and CD4 count before treatment, and IgG content was reduced also. After treatment, CD3, CD4, CD4/CD8 ratio as well as IgG and IgA were improved significantly (P < 0.01), IL-2R percentage approached normal. Moreover, the levels of Zn and Fe changed significantly (P < 0.01).

CONCLUSIONFZJPR could improve the trace elements content and immune function in CSDA children, so it is effective in treating CSDA.

A chiral high-performance liquid chromatography method was developed for the simultaneous determination of ibuprofen enantiomers in dog plasma. It was used to study the pharmacokinetics in the Beagle dog after intravenous administration of racemic-ibuprofen, S-ibuprofen and R-ibuprofen. Ketoprofen was chosen as the internal standard. After a simple precipitation using methanol as the precipitating solvent, both analytes and IS were separated on a Kromasil 100-5CHI-TBB chiral column (250 mm x4.6 mm, 5 μm) with isocratic elution using acetonitrile - 20 mmol x L(-1) phosphate buffer (pH 3.0, containing 5% methanol) (6 : 4) as the mobile phase. The detection wavelength was 220 nm. Liner calibration curves for both of the ibuprofen enantiomers were over the concentration range from 0.5 to 50 μg x mL(-1) with a lower limit of quantification of 0.5 μg x mL(-1), the accuracies were all in standard ranges. The intra- and inter- assay precisions were all below 7%. The recovery rate was 93.1% to 100.4%. The experiments proved that the method was simple, rapid and sensitive. It can be used in the quantitative determination of ibuprofen enantiomers in dog plasma. The method was used to determine the concentration of ibuprofen enantiomers in Beagle dog plasma after a single intravenous administration of racemic-ibuprofen, S-ibuprofen and R-ibuprofen (9 mg x kg(-1)) and the pharmacokinetics parameters were calculated based on the concentration-time curves. The C(max) of S-ibuprofen in Beagle dog plasma after a single intravenous administration of racemic-ibuprofen, S-ibuprofen and R-ibuprofen were 30.8 ± 4.7, 46.1 ± 5.9 and 20.0 ± 2.6 μg x mL(-1), respectively. In terms of the exposure of active ingredient, it revealed a significant difference between the administration of S-ibuprofen and the other two groups. The systematical R- to S- chiral inversion was discussed. Comparing the pharmacokinetic parameters at different doses, chiral inversion were 70.1% ± 36.6% and 76.4% ± 36.2%, respectively, after intravenous administration of racemic- and R-ibuprofen. This study provides a theoretical basis for the safety of ibuprofen formula of injection drug.
