Objective:To explore the clinical value of X-ray and CT in detecting unusual mediastinal mass.Methods:The chest plain films and CT scans were performed in all 9 cases .Results:Nine cases proved by operation and pathology included liposarcoma(two cases),multiple neurinoma(two cases),neuroendovrine cartinoma(two cases),endodermal sinus tumor(two cases)and thymas cacinoid (one case).Conclusion:X-ray and CT can localze the mediastinal mass,CT has more significance in detecting the internal morphology of mediastinal mass and its relationship with the surrounding tissues.But there is still a limitation for X-ray and CT in detecting the quality of some mediastinal carcinomas.

Objective:To investigate the regulation of acupuncture on γ-interferon (INF-γ) and tumor necrosis factor (TNF) of lung cancer-operative cases. Methods: to determine the INF-γ and TNF contents in the blood serum of lung cancer patients by double antibody sandwich immuno-enzymatic method (ELISA); to measure the INF-γ and TNF contents of 30 lung cancer patients in the acupuncture anesthesia group and 30 lung cancer patients in general anesthesia group before the operation and at the 8th days, the 12th day after the operation respectively and make comparison between the two groups. Results:The pre-operation INF-γ contents of the two groups showed no significant difference (P＞0.05); the post-operation INF-γ contents of the two groups showed significant difference at 8th day and 12th day after the operation (P＜0.05); the acupuncture anesthesia group was superior to the general anesthesia group; the self-comparison of the anesthesia group showed significant difference at the 12th day and 8th day after the operation (P＜0.05); the pre-operation TNF contents of the two groups showed no significant difference (P＞0.05) and the post-operation TNF contents of the two groups showed significant difference at the 8th day and 12th day after the operation (P＜0.05). Conclusion:Acupuncture can increase the serum INF-γ and TNF contents of lung cancer patients and therefore regulate the immunity of the patients.

OBJECTIVETo investigate the effects of rhodiola on expression of vascular endothelial cell growth factor (VEGF) and angiogenesis in aortic atherosclerotic plaque of rabbits.

METHODSThirty male New Zealand rabbits were randomly divided into 3 groups equally, i. e. the control group (A) fed with common diet and treated with distilled water, the high fat diet group (B) and the rhodiola group (C) fed with diet containing 1.5% cholesterol and treated respectively with distilled water and rhodiola (1 mL/kg per day), all the treatments were administered via gastrogavage once a day for 9 successive weeks. Level of blood lipids in various groups was determined and compared at the end of the experiment. Meanwhile, the tissue sample of aorta was taken for observation through HE and Sudan red staining, for detecting the CD34 positive response intensity by immunohistochemical staining and the VEGF expression by Real-time fluorescent quantitative PCR and Western blot.

RESULTSDetermination of blood lipids showed that in Group C, TC was 42.01 +/- 1.99 mmol/L, TG 4.83 +/- 0.75 mmol/L and LDL-C 38.40 +/- 0.74 mmol/L, all lower than those in Group B (70.74 +/- 2.66 mmol/L, 8.75 +/- 0.78 mmol/L and 51.05 +/- 0.34 mmol/L, respectively), showing statistical difference between groups (P < 0.05). The intima/media tunica thickness ratio and the CD34 positive area of plaque in Group C were all lower than those in Group B (0.35 +/- 0.03 vs 0.43 +/- 0.03 and 29.12 +/- 2.56% vs 39.28 +/- 3.48%, P <0.05). Besides, the VEGF expression in atherosclerotic plaque was also lower in Group C than that in Group B.

CONCLUSIONRhodiola has the effects of inhibiting atherosclerosis formation, decreasing the VEGF expression and suppressing the angiogenesis in the plaque.

OBJECTIVETo investigate the effects of Shexiang Baoxin Pill (SBP) in intervening atherosclerosis and myocardial infarction (AS-MI) in experimental animals, and inspect its influences on angiogenesis.

METHODSTwenty male New-Zealand rabbits were made into AS-MI model, and randomly divided into 2 groups equally. Group A was fed with high-fat diet for control; Group B was fed with high-fat diet but intervened with SBP. The cardiac function and the positive area of plaque were determined. The CD34 positive response intensity at infarcted marginal zone and aorta vessel wall, and the capillary density of myocardium were measured by immunohistochemical staining. In addition, the protein expressions of vascular endothelial growth factor (VEGF) and vascular endothelial growth factor receptor-2 (VEGFR-2) were detected by Western blot.

RESULTSCompared to Group A, the cardiac function was obviously improved (P<0.05) and the plaque positive area (%) was significantly decreased in Group B (45.82 +/- 3.68 vs 82.56 +/- 4.97, P<0.01). The CD34 positive response intensity and the capillary density as well as VEGF and VEGFR-2 expressions in infarcted marginal zone in Group A were higher than those in Group B (P<0.01); but these parameters at aorta vessel walls were lower in Group A than in Group B (P<0.01).

CONCLUSIONSBP could advance the angiogenesis in the marginal zone of infarction, improve heart function, and embarrass angiogenesis in atherosclerotic plaque.

Objective To promote the standardization of medical practice in China by comparing the discrepancies of diagnosis and medication strategies for benign prostatic hyperplasia (BPH) between urologists and geriatricians.Methods Departments of urology and geriatrics in general hospitals in China were selected through stratified sampling and 145 315 patients who went for the outpatient service in certain days during December 2011 to December 2012 were recruited by cluster.Questionnaires were completed by corresponding doctors and data of patient clinical characteristics as well as diagnostic and therapeutic pattern were collected.Results A total of 142 511 valid questionnaires were collected with 119 426 from urology and 23 085 from geriatrics.The average age of BPH patients was (68.34±8.61) years and the average IPSS was 17.93±4.73.The rates of diagnostic method were IPSS (99.2％),ultrasonic inspection (86.0％),digital rectal examination (DRE) (66.0％) and urine flow rate test (55.2％).The rate of ultrasonic application was lower while the rates of other methods were higher among urologists (P＜0.01) ; the rate of DRE among urologists was 2.2 times to that among geriatricians.For patients with moderate or severe symptoms,most urologists (72.1％ in moderate patients and 79.9％ in severe patients) applied drug-combination strategy and the rate was 2 times to that among geriatricians (P＜0.01).In contrast,most geriatricians (59.7％ in moderate patients and 56.1％ in severe patients) applied single drug to BPH patients.Urologists utilized α-receptor blockers,plant preparations and traditional Chinese medicine more frequently than geriatricians (P＜0.01).Conclusions Urologists performed more integrated diagnosis strategy compared with geriatricians.The urologists tended to use 5α-reductase inhibitor combined with α-receptor blocker to treat BPH patients with moderate or severe symptoms,while geriatricians preferred 5α-reductase inhibitor alone.

Objective To evaluate a modified technique for digestive tract reconstruction after pancreaticoduodenectomy(PD).Methods 171 admitted patients were enrolled from January 2012 to January 2014 at our department.According to the preoperative CT scan and intraoperative exploration,pancreaticogastrostomy was performed in cases of soft pancreas texture,while pancreaticojejunostomy was performed in fibrotic pancreas after PD.Bypassed biliary-pancreatic reconstruction were applied on all cases.Results For the digestive tract reconstruction after PD,92 patients underwent pancreaticogastrostomy,79 patients underwent pancreaticojejunostomy.The median time for the surgery was 240.0 minutes (ranging from 186 to 414 min).Operative mortality was zero,and morbidity was 18.1％ (n =31),including hemorrhage (n =4),biliary fistula (n =3),pulmonary infection (n =2),adipose liquefaction and operative incision infection (n =0),delayed gastric emptying (DGE) (n =6),abdominal abscess (n =4).Fout patients developed a pancreatic fistula (type A in 2,type B in 2).Conclusions Modified pancreaticogastrostomy,pancreaticojejunostomy and biliary-pancreatic bypass is safe for digestive tract reconstruction after pancreaticoduodenectomy.

OBJECTIVETo investigate the changes in the levels of monocarboxylate transporter-2 in spinal cord horn in a rat model of chronic inflammatory pain.

METHODSMale SD rats weighting 180 - 220 g were randomly divided into two groups(n = 48): normal saline group (NS group), complete Freund's adjuvant group (CFA group). Rats were given injections of CFA 100 µl in left hind paw in group CFA, and an equal volume of saline was given injection in group NS. Mechanical withdraw threshold(MWT) and thermal withdraw latency(TWL) were measured at before injection(T0 and 3 h, 1 d, 3 d, 7 d, 14 d, and 21 d after injection(T1-7). Four rats were chosen from each group at T0-7 and sacrificed, and L4-5 segments of the spinal cord horn were removed for measurement of the expression of monocarboxylate transporter-2 by Western blot analysis.

RESULTSIn CFA group, mechanical hyperalgesia and allodynia appeared on the 3 h after CFA injection, then until the day 14. The expression of monocarboxylate transporter-2 in the spinal dorsal horn of rats in CFA group was significantly higher than that in normal control group at T1-6(P <0.05). The protein level of monocarboxylate transporter-2 was apparently correlated with MWT and TWL(P <0.01 and P <0.05) in CFA group.

CONCLUSIONThe level of monocarboxylate transporter-2 in spinal dorsal horn is significantly increased in a rat model of chronic inflammatory pain and the change may involve in the formation and maintenance of central sensitization in spinal cord of chronic inflammatory uain.
