Gastric bronchogenic cysts (GBCs) is uncommon with atypical clinical features. It is difficult to diagnose by preoperative imaging examinations. Therefore , postoperative histopatho-logical examination is regarded as the golden bacteria in ultimate diagnosis. The treatment of GBCs:ultrasound-guided fine needle aspiration and endoscopic mucosal resection is only used for small GBCs with intra-cavity growth pattern. However , GBCs with extra-cavity growth pattern is featured with deeply anatomical position , large size , and prone on attaching to vital blood vessels and organs , which makes laparoscopic resection is the first choice in treatment. The authors introduce the diagnosis and treatment of a case of GBCs attaching to lesser curvature , in order to provide references for clinical diagnosis of GBCs.

OBJECTIVETo study on the original meanings of "reinforcement can be achieved by slow-yet-rapid needling, and rapid-yet-slow needling weakens evil-qi", one of important bases of reinforcing-reducing in acupuncture.
METHODSUsing the principle of knowledge archaeology and through structure an d through structure analysis on the subjects described by "slow" and "rapid" and the papers appearing the words, the meanings of this sentence are re-discriminated.
CONCLUSION"Slow-rapid" prescribed in the reinforcing-reducing needling method in Huangdi's Internal Classic includes 3 subjects: pulse condition, needle-retained time, and velocity of withdrawing the needle. The "slow-rapid" in "reinforcement can be achieved by slow-yet-rapid needling, and rapid-yet-slow needling weakens evil-qi" should be pulse condition, but was not needling method, which means that the pulse changes from slow to rapid, marked by transformation of channels from deficiency to excess; the transform of the pulse from rapid to slow means that the channel transforms from excess to deficiency.

OBJECTIVETo compare the effect of transurethral resection of the prostate combined with endocrine therapy (TURP + ET) with that of αlA-blockers combined with ET ((αlA-b + ET) in the treatment of bladder outlet obstruction (BOO) in patients with advanced prostate cancer (PCa), and to investigate the safety of the TURP + ET for the treatment of PCa with BOO.
METHODSWe retrospectively analyzed 63 cases of PCa with BOO, 28 treated by αlA-b + ET and the other 35 by TURP + ET. We obtained the residual urine volume (RV), maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), and quality of life score (QoL) before and after treatment along with the overall survival rate of the patients, followed by comparison of the parameters between the two methods.
RESULTSAt 3 months after treatment, RV, IPSS, and QoL in the TURP + ET group were significantly decreased from (137.8 ± 27.6) ml, (22.3 ± 3.6), and (4.2 ± 0.8) to (29 ± 13.6) ml, (7.8 ± 2.1), and (1.6 ± 0.5) respectively (P < 0.05), while Qmax increased from (5.6 ± 2.1) ml/s to (17.6 ± 2.7) ml/s (P < 0.05); the former three parameters in the αlA-b + ET group decreased from (133.6 ± 24.9) ml, (21.5 ± 3.2), and (4.7 ± 1.1) to (42 ± 18.3) ml, (12.8 ± 2.6), and (2.5 ± 0.7) respectively (P < 0.05), while the latter one increased from (6.3 ± 2.4) ml/s to (11.7 ± 2.3) ml/s (P < 0.05), all with statistically significant differences between the two groups (P < 0.05). The overall survival rate of the TURP + ET group was not significantly different from that of the αlA-b + ET group (51.4% vs 46.4% , P > 0.05).
CONCLUSIONTURP + ET is preferable to αlA-b + ET for its advantage of relieving BOO symptoms in advanced PCa without affecting the overall survival rate of the patients.

Ultrasonic microbubbles were used to open blood-brain barriers (BBB) with a reversed and limited behavior feature in the study, which could improve the brain-targeted delivery of anti-tumor drugs. The glioma rat model was prepared. Low-frequency ultrasound was combined with microbubbles to affect the permeability of BBB compared with the permeability of independently administered Evans blue (EB) crossing BBB. Time point and length of ultrasound were investigated whether they affect the permeability of BBB and the damage of brain tissue. The effect of the growth time of glioma on BBB permeability was explored. Only glioma had a very little impact on BBB permeability. However, ultrasonic microbubbles opened the BBB with the features of temporary, limited and reversed behavior and improved EB and magnetic resonance imaging contrast agent penetrating BBB. A length of 30 s ultrasound is appropriate for opening BBB and no damage of brain tissue. Drugs should be injected before ultrasound so that they enter into brain as BBB opening. Ultrasonic microbubbles can open BBB effectively and safely, which improve drugs penetrating BBB under proper time point and length.

Objective: In order to investigate the effects of activating and blocking Stat3 signaling pathway on invasion ability of human pancreatic cancer cells and explore its action mechanism.Methods:Human pancreatic cancer Capan-2 cells were treated with IL-6. SW1990 human pancreatic cancer cells were treated with AG490. Cell proliferation was measured by MTT assay. Western blotting and immunocytochemistry were performed to detect expression of phosphorylated Stat3 (p-Stat3) protein. Real-time fluorogentic quantitative PCR (RFQ-PCR) and Western blotting were used to detect the mRNA and protein expression of VEGF and MMP-2 mRNA, respectively. The invasion abilities of SW1990 and Capan-2 cells were determined by cell invasion assay in vitro. Results:IL-6 stimulated the proliferation of Capan-2 cells (P<0.05), elevated the expression of p-Stat3, increased the mRNA and protein expressions of vascular endothelial growth factor (VEGF) and matrix metalloproteinase 2 (MMP-2) (P<0.05), and enhanced the invasion ability of Capan-2 cells. AG490 inhibited the proliferation of SW1990 cells (P<0.05), down-regulated the expression of p-Stat3, markedly decreased the mRNA and protein expression of VEGF and MMP-2 (P<0.05), and weakened the invasion ability of SW1990 cells. Conclusion:Stat 3 signaling pathway plays an important role in the invasion and metastasis of pancreatic cancer. Stat 3 signaling transduction pathway may provide a novel therapeutic target for the treatment of pancreatic cancer.

OBJECTIVETo observe the clinical effects of two different circumcision procedures with the Shang Ring and compare their advantages and disadvantages.
METHODSA total of 527 adult males with phimosis or redundant prepuce underwent Shang Ring circumcision by conventional outward replacement (n = 254) and inward placement (n = 273), respectively. We observed the in-ring nocturnal pain, complications, ring-removal pain, degree of edema, recovery time, and patients' satisfaction after surgery, and compared them between the two groups.
RESULTSCompared with the conventional outward placement (5.9%) of the Shang Ring, the inward placement method showed the advantages of mild in-ring nocturnal pain, a low complication rate, significantly reduced ring-removal pain, and mild edema, but exhibited longer healing time.
CONCLUSIONIn Shang Ring circumcision for phimosis and redundant prepuce in adult males, each of the outward and inward placement methods has advantages and disadvantages of its own, but the latter is more advantageous and feasible.
