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.

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.

This study was aimed to compare the activation of daidzein and puerarin on antioxidation, NO and NOS suppression in vitro . The RAW264 . 7 cell line was used to prepare radical reaction model induced by LPS (1 μg/mL). MTT method was adopted to detect cytotoxicity of daidzein and puerarin. The DCFH-DA probe and confocal microscopy were used to examine the antioxidant ability of daidzein and puerarin. Griess reagent was adopted to test the NO level in the culture medium. And chemical colorimetry was used to detect the content in RAW264.6 cells. The results showed that daidzein and puerarin can significantly suppress the NO and T-NOS expression in RAW264.7 cells induced by LPS. It was concluded that there was no difference on the activation of antioxidant free radical between daidzein and puerarin . In this regard , daidzein can be the used as substitutes of puerarin .

This study was aimed to observe the pharmacodynamics of genistein combined with tripterygium gly-cosides ( GTW ) in the rheumatoid arthritis ( RA ) treatment of ovariectomized rats . SD rats were randomly divid-ed into four groups , which were the sham-operation group , model group , Methotrexate ( MTX ) treatment group ( 2.7 mg/kg ) , and genistein ( 30 mg/kg ) combined with GTW ( 70 mg/kg ) treatment group . There were ten rats in each group . Except the sham-operation group , rats in other groups were ovariectomized and immunized by collagen type II to prepare collagen induced arthritis ( CIA ) model . The intragastric administration of drugs was given once a day for two weeks . The arthritis index , joints swelling degree , and levels of anti-Col II , IL-6 and IL-10 in serum were tested . The results showed that the arthritis index , joints swelling degree , and levels of anti-Col II , IL-6 and IL-10 in serum were all significantly increased in the model group ( P < 0 . 05 or P< 0 . 01 ) . Compared with the model group , the arthritis index and joints swelling degree of both MTX and genistein combined with GTW were significantly decreased . The level of anti-Col II in serum of the MTX treatment group was significantly decreased ( P < 0 . 05 ) . However , there were no significant changes on levels of IL-6 and IL-10 . The levels of anti-Col II and IL-6 in serum of the genistein combined with GTW were significantly decreased ( P < 0 . 05 ) . The level of IL-10 was significantly increased ( P < 0 . 01 ) . It was conclud-ed that genistein combined with GTW can significantly inhibit the pathological progress of CIA on ovariec-tomized rats . Compared with MTX , the genistein combined with GTW received a better regulating effect on the expression of IL-6 and IL-10 . The results suggested that phytoestrogen combined with GTW played a good therapeutic effect on gonadal dysfunction type of RA . It provided novel strategies and experimental evidences on postmenopausal RA treatment in the clinical practice .

Objective To explo the antioxidant effect and molecular mechanism of gastrodin (Gas) in epilepsy (EP) rats induced by LiCl-pilocarpine (PILO) . Methods Eighty male SD rats were randomly divided into 5 groups: sham group, EP group, therapy groups (pretreated with 60 mg/kg, 90 mg/kg, 120 mg/kg of gastrodin respectively) . The EP model was esteblished by peritoneal injection of LiCl-PILO. Therapy groups were pretreated with various concerntration of Gas. The control group was given the same dosage of normal saline. The alteration of behavior was observed, the concentration of catalase (CAT), glutathion (GSH), superoxide dismutase (SOD), glutathion reductase (GR), total antioxidtion (T-AOC) and malondialdehyde (MDA) in rats brain cortex were detected by chemical colorimetric method, phosphorylation of p38 was determined by western blot. Results There was no EP seizure in sham group,and the EP seizure degree in therapy groups (gas pretreated groups) was significantly decreased,and had statistically significant difference with EP group (P<0.05) . The EP model rats exhibited a significant decrease in the concentration of endogenous antioxidants (CAT, GSH, SOD, GR and T-AOC), while an increase of the concentration of MDA and phosphorylation p38 protein as compared to sham group (P<0.05) . After treatment of the Gas,treatment group rats attenuated the seizure degree,exhibited a significant increase of the concentration of endogenous antioxidants (P<0.05),while a decrease in concentration of MDA and phosphorylation of p38 as compared to model group (P<0.05) . Conclusion Gas may have a neuroprotective role in central nervous system of epileptic rats modle by down-regulateing the seizure degree and the activity of p38 kinase and up-regulateing the content of endogenous antioxidants.
