We studied the effects of granulocytic elastase (GEL) and fibronectin (FN) on the coagulation and fibrinolytic system when using cardiopulmonary bypass (CPB). Blood sampling was performed before CPB (Pre), just after CPB (Post) the 1st postoperative day (PD1) and the second postoperative day (PD2). Laboratory parameters were GEL, FN, fibrinogen (Fib), prothrombin time (PT), fibrin degradation products (FDP), D dimer (D-D), α2 plasmin inhibitor plasmin complex (PIC) and antithrombin III (AT III). The level of GEL was highest and that of FN was lowest at Post. The levels of Fib, PT and AT III were lowest and that of PIC was highest just after CPB. The levels of FDP and D-D were highest on PD1. The levels of GEL and D-D correlated just after CPB and on PD1 and PD2. The level of GEL correlated with that of PIC on PD1. These results demonstrated that the level of FN decreased with CPB. And it was expected that CPB time affected the level of GEL. The levels of GEL affects D-D and PIC which are fibrinolysic factors particularly related to secondary fibrinolysis.

A Case of abdominal aortic occlusion caused by acute aortic dissection (DeBakey's type III b) is reported. A 59-year-old woman was admitted with sudden onset back pain and sensory disturbance of bilateral lower extremities. The pulsations of bilateral femoral arteries were absent. CT and aortogram revealed dissection of the thoracic descending aorta and infrarenal aortic occlusion. Since ischemic change had progressed, bilateral axillofemoral bypass was performed for limb salvage, and the symptoms improved rapidly. Axillofemoral bypass is an easy and safe procedure even in the acute phase of aortic dissection. It provides fast reperfusion, and so is considered to be useful to preventing myonephrotic metabolic syndrome MNMS.

We investigated original texts for yokukansan, a familiar Kampo formula, focusing on the classical literature Xue-shi yi-an (薛氏医案) . Yokukansan was described in the Bao-ying jin-jing-lu (保嬰金鏡録) written by Xue ji (薛己) in 1550, the Xiao-er yao-zheng zhi-jue (小児薬証直訣) revised by Xue ji (薛己) in 1551,the Bao-ying cuo-yao (保嬰撮要) by Xue kai (薛鎧) in 1556, and the Xiao-er dou-zhen fang-lun (小児痘疹方論) in 1550. The phrase “one's own work” was used in “Bao-ying jin-jing-lu (保嬰金鏡録)” and in the Xiao-er dou-zhen fang-lun (小児痘疹方論) by Chen wen-zhong (陳文仲). However, there was no mention of “one's own work” in the same title, the Xiao-er dou-zhen fang-lun (小児痘疹方論), as summarized by Xiong zong-li (熊宗立).
Yokukansan was found only in the Xiao-er yao-zheng zhi-jue (小児薬証直訣) revised by Xue ji (薛己) in 1551, but not in the other copies of the same text. Therefore, it seems likely that yokukansan was created by Xue ji (薛己) himself.
Yokukansan was previously thought to have originated with the Bao-ying cuo-yao (保嬰撮要). However, based on use of the phrase “one's own work” in the classical literature, it appears that the original text for yokukansan should be the Bao-ying jin-jing-lu (保嬰金鏡録). Therefore, yokukansan seems to have been made by Xue ji (薛己), and not Xue kai (薛鎧), who was his father.

Methods:
Five formalin-embalmed human cadavers were used. We assessed the proportion of segmental arteries and veins that intersected the IVD in the L2–L5 range and their course on the anterior part of the spinal column.
Results:
The segmental arteries and veins commonly intersect the anterior part of the IVD (artery, 28.1%; vein, 42.1%). Seven of 10 (70%) segmental arteries at L2 intersected the IVD, but only one artery intersected the IVD at L3 and L4. The proportions of segmental veins that intersected the IVD were 60%, 50%, and 16.7% at L2, L3, and L4, respectively.
Conclusions
The segmental arteries and veins frequently intersect the IVD in the anterior part of the spinal column. Therefore, it is necessary to consider these individual anatomical features to prevent vascular damage during lateral lumbar interbody fusion surgery.

Endoscopic ultrasonography (EUS) combines endoscopy and intraluminal ultrasonography, and allows imaging with a high-frequency transducer over a short distance to generate high-resolution ultrasonographic images. EUS is now a widely accepted modality for diagnosing pancreatobiliary diseases. EUS-guided fine-needle aspiration (EUS-FNA) using a curved linear-array echoendoscope was initially described more than 20 years ago, and since then many researchers have expanded its indications to sample diverse lesions and have also used it for various therapeutic purposes. EUS-guided biliary drainage (EUS-BD) is one of the therapeutic procedures that has been developed using a curved linear-array echoendoscope. Technically, EUS-BD includes rendezvous techniques via transesophageal, transgastric, and transduodenal routes, EUS-guided choledochoduodenostomy (EUS-CDS), and EUS-guided hepaticogastrostomy (EUS-HGS). Published data have demonstrated a high success rate, albeit with a comparatively high rate of nonfatal complications for EUS-CDS and EUS-HGS, and a comparatively low success rate with a low complication rate for the rendezvous technique. At present, these procedures represent an alternative to surgery or percutaneous transhepatic biliary drainage (PTBD) for patients with obstructive jaundice when endoscopic biliary drainage (EBD) has failed. However, these procedures should be performed in centers with extensive experience in linear EUS and therapeutic biliary ERCP. Large prospective studies are needed in the near future to establish standardized EUS-BD procedures as well as to perform controlled comparative trials between EUS-BD and PTBD, between rendezvous techniques and direct-access techniques (EUS-CDS and EUS-HGS), and between EBD and EUS-BD.

AIMTo evaluate the safety and efficacy of an extract of Ganoderma lucidum that shows the strongest 5alpha-reductase inhibitory activity among the extracts of 19 edible and medicinal mushrooms by a double-blind, placebo-controlled, randomized and dose-ranging study in men with lower urinary tract symptoms (LUTS).
METHODSIn this trial, we randomly assigned 88 men over the age of 49 years who had slight-to-moderate LUTS to 12 weeks of treatment with G. lucidum extract (6 mg once a day) or placebo. The primary outcome measures were changes in the International Prostate Symptom Score (IPSS) and variables of uroflowmetry. Secondary outcome measures included changes in prostate size, residual urinary volume after voiding, laboratory values and the reported adverse effects.
RESULTSG. lucidum was effective and significantly superior to placebo for improving total IPSS with 2.1 points decreasing at the end of treatment (mean difference, -1.18 points; 95% confidence interval, -1.74 to -0.62; P < 0.0001). No changes were observed with respect to quality of life scores, peak urinary flow, mean urinary flow, residual urine, prostate volume, serum prostate-specific antigen or testosterone levels. Overall treatment was well tolerated with no severe adverse effects.
CONCLUSIONThe extract of G. lucidum was well tolerated and improved IPSS scores. These results encouraged a further, large-scale evaluation of phytotherapy for a long duration using the extract of G. lucidum on men with LUTS.

Methods:
HFCs were obtained from patients with LSS who underwent surgery. HFCs were stimulated by tumor necrosis factor-α (TNF-α) and a p38 MAP kinase inhibitor, SB203580. Phosphorylation of the p38 MAP kinase was analyzed by western blotting. The concentration of interleukin-6 (IL-6) in the conditioned medium was measured by enzyme-linked immunoassay and IL-6 messenger RNA expression levels were determined by real-time polymerase chain reaction.
Results:
TNF-α induced the phosphorylation of p38 MAP kinase in a time-dependent manner, which was suppressed by the p38 MAP kinase inhibitor, SB203580. TNF-α also stimulated IL-6 release in both a time- and dose-dependent manner. On its own, SB203580 did not stimulate IL-6 secretion from HFCs; however, it dramatically suppressed the degree of IL-6 release stimulated by TNF-α from HFCs.
Conclusions
This is the first report suggesting that TNF-α stimulates the gene expression and protein secretion of IL-6 via p38 MAP kinase in HFCs. A noted association between tissue hypertrophy and inflammation suggests that the p38 MAP kinase inflammatory pathway may be a therapeutic molecular target for LSS.

Journal of Gynecologic Oncology 2021;32(1):e9-
Objective:
The standard dose for pegylated liposomal doxorubicin (PLD) is 50 mg/m2 every 4 weeks. While 40 mg/m2 has recently been used in clinical practice, evidence supporting this use remains lacking.
Methods:
This phase III randomized, non-inferiority study compared progressionfree survival (PFS) for patients with platinum-resistant ovarian carcinoma between an experimental arm (40 mg/m2 PLD) and a standard arm (50 mg/m2 PLD) until 10 courses, disease progression or unacceptable toxicity. Eligible patients had received ≤2 prior lines.Stratification was by performance status and PFS of prior chemotherapy (<3 months versus ≥3 months). The primary endpoint was PFS and secondary endpoints were overall survival (OS), toxicity profile, clinical response and tolerability. The total number of patients was 470.
Results:
The trial was prematurely closed due to slow recruitment, with 272 patients randomized to the experimental arm (n=137) and standard arm (n=135). Final analysis was performed with 234 deaths and 269 events for PFS. In the experimental arm vs. standard arm, median PFS was 4.0 months vs. 4.0 months (hazard ratio [HR]=1.065; 95% confidence interval [CI]=0.830–1.366) and median OS was 14.0 months vs. 14.0 months (HR=1.078; 95% CI=0.831–1.397). Hematologic toxicity and oral cavity mucositis (≥grade 2) were more frequent in the standard arm than in the experimental arm, but no difference was seen in ≥grade 2 hand-foot skin reaction.
Conclusion
Non-inferiority of 2 PLD dosing schedule was not confirmed because the trial was closed prematurely. However, recommendation of dose reduction of PLD should be based both on efficacy and safety.

OBJECTIVEPrevious studies on the association between physical activity (PA) and neighborhood environments (NE) focused on either objectively measuring the NE or the residents' perception of NE. Here, we investigate which actual or perceived NE is associated with residents' PA in Japan.
METHODSTwo regions with an objectively assessed high and low residential density, land use mix-diversity, and street connectivity, respectively, were identified in one city. The subjects were selected using a stratified random sampling method by sex and age in each region. The NE of the subjects was objectively measured using the Geographic Information System (GIS), and the subjects' perception of the NE was assessed using a questionnaire. The daily total number of walking steps was measured with an accelerometer, and walking and cycling time were assessed by a questionnaire.
RESULTSFor the female subjects, the mean cycling time, subjectively assessed as a means of transport, was significantly longer in the group with a high GIS score for the number of land use types, while the score for total number of walking steps was significantly higher among those who were aware of places to walk to, and cycling time for transport was longer for those who perceived an accessibility to post offices, banks/credit unions, gymnasiums/fitness facilities, and amusement facilities in their neighborhood. For the male subjects, the score for walking time for leisure was longer for those who perceived aesthetics and an accessibility to parks, and the score for total walking steps was significantly higher for those who perceived an accessibility to bookstores or rental video stores in their neighborhood.
CONCLUSIONSThe results to this study demonstrate that daily PA was high among female subjects living in a NE with land use mix-diversity, and who had an awareness of places to walk to and the accessibility to facilities for daily necessities in their neighborhood. For male subjects, daily PA was high among those who perceived the aesthetics of and accessibility to facilities for pleasure in their neighborhood. Further research is needed to determine the association between PA and NE on the basis of sex differences.
