Abstract
OBJECTIVE This study examined changes in wound symptoms and the health-related quality of life (HRQoL) of patients with newly diagnosed malignant fungating wounds, and explored the factors that impacted the changes in HRQoL. METHOD This prospective longitudinal study included patients from three hospitals in China who had been diagnosed with malignant fungating wounds. Questionnaires were used to assess patients' HRQoL and their wound symptoms at the time of diagnosis (T0), as well as at one, three and six (T1, T2 and T3, respectively) months following the treatment period. Factors related to changes in HRQoL were analysed using generalised estimating equation models. RESULTS A total of 162 patients were included in the study. The patients reported low overall HRQoL. In three health-related dimensions (functional status, social relations and mental health), patients reported lower functional status at the time of wound diagnosis (T0), which then increased slowly with treatment over time. A lower QoL was associated with odour, exudate, bleeding, pruritus, a low performance status and the need for the dressing of wounds. CONCLUSION The HRQoL of patients with malignant fungating wounds exhibited significant changes across different periods. It is thus of great importance to formulate pragmatic, patient and family-centred palliative wound care management strategies.

Abstract
BACKGROUND Microwave ablation (MWA) is an effective treatment option for patients with primary liver cancer. However, it has been reported that the MWA procedure induces a hepatic inflammatory response and injury, which may negatively affect the efficacy of MWA. As such, the discovery of reliable markers to monitor the patient’s response to MWA is needed. Golgi protein 73 (GP73) has been shown to be associated with chronic liver disease. To date, the potential value of serum GP73 in the dynamic monitoring during MWA of liver cancer remains unclear.
AIM To examine the effects of MWA on the serum levels of GP73 in patients with primary liver cancer.
METHODS A total of 150 primary liver cancer patients with a single small lesion (≤ 3 cm in diameter) were retrospectively enrolled spanning the period between January 2016 and October 2018. All of the patients received MWA for the treatment of primary liver cancer. Serum GP73, alpha-fetoprotein (AFP), and widely used liver biochemical indicators [serum albumin, total bilirubin (TBIL), alanine aminotransferase (ALT), and aspartate aminotransferase (AST)] were compared before MWA and at different time points, including 1, 2, and 4 wk following the ablation procedure.
RESULTS Complete tumor ablation was achieved in 95.33% of the patients at 1 mo after MWA. The 1-, 2-, and 3-year disease-free survival rates were 74.67%, 59.33%, and 54.00%, respectively. The serum AFP levels were significantly decreased at 1, 2, and 4 wk after MWA; they returned to the normal range at 12 wk after MWA; and they remained stable thereafter during follow-up in those cases without recurrence. In contrast, the serum GP73 levels were significantly increased at 1 and 2 wk after MWA. The serum GP73 levels reached the peak at 2 wk after MWA, started to decline after hepatoprotective treatment with glycyrrhizin and reduced glutathione, and returned to the pretreatment levels at 12 and 24 wk after MWA. Notably, the changes of serum GP73 in response to MWA were similar to those of TBIL, ALT, and AST.
CONCLUSION Serum GP73 is markedly increased in response to MWA of liver cancer. Thus, serum GP73 holds potential as a marker to monitor MWA-induced inflammatory liver injury in need of amelioration.

Abstract
Memantine (MEM) is used for improving the cognitive impairments of the patients suffering from Alzheimer's disease (AD) by multiple neuroprotective mechanisms. However, it is still not clear whether nerve growth factor (NGF) signaling is involved in the mechanisms of MEM. The present study investigated the neuroprotective effects of MEM treatment on the cognitive performance and amyloidosis in APP/PS1 transgenic mice, and disclosed the NGF-related mechanism of MEM. We found that MEM treatment improved the cognitive performance by decreasing the escape latency and path length in the navigation test, by shortening the duration in target quadrant and reducing the frequency to pass through the target in probe trial, and by prolonging the latency and decreasing the frequencies of entering the dark compartment in passive avoidance test. The over-expressions of Aβ(1-42) and amyloid precursor protein (APP) were also decreased in the brains of APP/PS1 mice. Interestingly, MEM treatment improved the decreased NGF levels in APP/PS1 mice. Furthermore, NGF/TrkA signaling was activated by increasing the phosphorylation levels of tyrosine kinase (TrkA), proto-oncogene serine/threonine-protein kinase, Raf1 (c-Raf), extracellular regulated protein kinases (ERK)1/2 and cAMP-response element binding protein (CREB) after MEM treatment. Simultaneously, MEM also inhibited NGF/p75(NTR) signaling via decreasing the cleavage substrate of p75(NTR), increasing the JNK2 phosphorylation and decreasing the levels of p53 and cleaved-caspase 3. Therefore, the dual-regulation on NGF signaling was attributed to the improvements of cognitive deficits and Aβ depositions in APP/PS1 mice. In conclusion, MEM treatment activated the NGF/TrkA signaling, and inhibited the p75(NTR) signaling in APP/PS1 mice to ameliorate the behavioral deficits and amyloidosis, indicating that NGF signaling was a new potential target of MEM treatment for AD therapy.

Abstract
Fanconi anemia complementation group F protein (FANCF) is a key factor, which
maintains the function of FA/BRCA, a DNA damage response pathway. However, the
functional role of FANCF in breast cancer has not been elucidated. We performed a
specific FANCF-shRNA knockdown of endogenous FANCF in vitro. Cell
viability was measured with a CCK-8 assay. DNA damage was assessed with an alkaline
comet assay. Apoptosis, cell cycle, and drug accumulation were measured by flow
cytometry. The expression levels of protein were determined by Western blot using
specific antibodies. Based on these results, we used cell migration and invasion
assays to demonstrate a crucial role for FANCF in those processes. FANCF shRNA
effectively inhibited expression of FANCF. We found that proliferation of FANCF
knockdown breast cancer cells (MCF-7 and MDA-MB-435S) was significantly inhibited,
with cell cycle arrest in the S phase, induction of apoptosis, and DNA fragmentation.
Inhibition of FANCF also resulted in decreased cell migration and invasion. In
addition, FANCF knockdown enhanced sensitivity to doxorubicin in breast cancer cells.
These results suggest that FANCF may be a potential target for molecular, therapeutic
intervention in breast cancer.

Abstract
The main objective of this study was to investigate the pharmacokinetic characters of eszopiclone (CAS: 138729-47-2) after single and multiple-dose oral administration in healthy adult Chinese volunteers.In single-dose study, 12 subjects were given oral administrations of 1.5, 3 and 6 mg eszopiclone in an open-label, randomized, crossover fashion. In multiple-dose study, 8 subjects were given 3 mg eszopiclone once daily consecutively for 7 days. Blood samples were collected over 24 h and plasma eszopiclone were determined using a validated liquid chromatography/mass spectrometry (LC/MS/MS) assay. The safety and tolerability of eszopiclone was evaluated by adverse events recording, physical examination, laboratory testing, vital signs, and 12-lead ECG findings.The main pharmacokinetic parameters of eszopiclone after single-dose administration were as follows: doses of 1.5, 3 and 6 mg; Cmax of 18.08±4.65, 38.29±15.41 and 76.38±23.34 ng/ml; Tmax of 0.94±0.39, 1.04±0.63 and 1.08±0.51 h; AUC0-24 of 110.90±23.06, 227.36±62.41 and 504.10±140.13 ng*h/ml; elimination half-lives of 5.84±1.03, 5.53±1.91 and 6.17±1.23 h. After multiple-dose administration, the steady-state levels of eszopiclone were achieved by the 4th day, and the main pharmacokinetic parameters were Css_max at 33.43±5.63 ng/ml and AUCss (0-24) at 263.30±51.21 ng*h/ml. The most common adverse event was bitter or abnormal taste. All the adverse events were judged as mild to moderate and resolved without any medication.The pharmacokinetic character of eszopiclone is linear and dose-proportional over the range of 1.5-6 mg. The systemic exposure does not accumulate with once-daily administrations. Eszopiclone appears to have good safety and is well tolerated.

Abstract
The purpose of the study is to examine the differences in insulin resistance and postprandial triglyceride (TG) response between hypertensive patients with or without hypertriglyceridaemia. The study is a comparative cohort study with matching. Thirty-one newly diagnosed hypertensive patients without any medication were recruited from a health survey. The participants were further divided into two groups: those with fasting TG <2.26 mmol/L, and those with TG between 2.26 and 5.65 mmol/L. Both groups were matched in age, sex, body mass index and waist circumference. Each patient received a 75-g oral glucose tolerance test, an insulin suppression test, and a 1000 kcal high fat mixed meal test. The hypertriglyceridaemic hypertensive patients had significantly higher fasting insulin, 2-h plasma glucose, 2-h insulin, and steady-state plasma glucose (SSPG) (13.16 +/- 1.87 vs 9.76 +/- 3.18 mmol/L). They also had a greater postprandial TG response to the challenge of mixed meal (DeltaAUC 20.76 +/- 10.06 vs 7.97 +/- 3.18 mmol 8 h/L). The postprandial TG response was closely correlated (r = 0.72-0.95, P < 0.0001) with fasting TG in all hypertensive patients. Both fasting TG levels and postprandial TG response were significantly (P < 0.05) correlated with SSPG. In conclusion, the hypertensive patients with hypertriglyceridaemia were more insulin resistant than those without it. Exacerbation of postprandial hypertriglyceridaemia was identified in these patients. The TG response to the challenge of high fat meal was significantly correlated with fasting TG and insulin resistant in them. The results provide a rationale for the alleviation of insulin resistance and hypertriglyceridaemia in these atherosclerosis-prone hypertensive patients.

Abstract
AIM To detect inositol 1,4,5-triphosphate (IP3) formation of pregnant and nonpregnant human myometrial cells induced by acetylcholine (ACh). METHODS [3H] IP3 competitive protein binding assay. RESULTS Basal levels of IP3 in pregnant and nonpregnant human myometrial cells were (82 +/- 9) and (96 +/- 10) nmol.g-1 (protein), respectively (n = 6). Incubated with ACh 50 mumol.L-1 for 5 min, IP3 reached the peak levels (109 +/- 11) and (122 +/- 15) nmol.g-1 (protein), respectively (n = 6), but difference of the increments of IP3 in pregnant and nonpregnant women was not significant. The increased IP3 induced by ACh was inhibited by atropine (Atr) 1 mumol.L-1. CONCLUSION The basal IP3 level in pregnant cervix myometrial cells was higher than that in nonpregnant women. ACh increased the IP3 formation.

Abstract
OBJECTIVE To explore the distribution pattern for serum lipid concentrations among patients with different degrees of chronic renal failure; to study the characteristics of abnormal lipid metabolism for chronic renal failure patients when the disease progress further. SETTING No. 255 Hospital of PLA, Tangshan, Hebei, China; No. 281 Hospital of PLA, Beidanhe, Hebei, China; and the General Hospital of Beijing Military Region, Beijing, China. PRACTICE DESCRIPTION A total of 240 serum/urine samples from 50 healthy volunteers and from 190 patients with different degrees of chronic renal failure, which fall into four groups according to their glomerular filtration rates, were measured for serum levels of triglyceride, lipoprotein(a), lipoprotein(a) cholesterol, total cholesterol, apolipoprotein A1, apolipoprotein B100, low density lipoprotein cholesterol, high density lipoprotein cholesterol, and for urine albumin concentrations; the levels of these criteria were compared between the control group and diseased groups; the mean concentrations of different lipid variables were paired and subjected to linear regression analysis. MAIN OUTCOME MEASUREMENTS Glomerular filtration rates were estimated by the iohexol clearance method, in which plasma content of iohexol was measured with high performance liquid chromatography; concentrations of triglyceride, lipoprotein(a), lipoprotein(a) cholesterol, total cholesterol, apolipoprotein A1, apolipoprotein B100, low density lipoprotein cholesterol, high density lipoprotein cholesterol, and albumin were assayed according to standard protocols. RESULTS Serum levels of triglyceride, lipoprotein(a), lipoprotein(a) cholesterol, total cholesterol, apolipoprotein A1, apolipoprotein B100, low density lipoprotein cholesterol, and urine albumin contents were significantly higher, whereas those of high density lipoprotein cholesterol were lower, in diseased groups than that of the control (p < 0.05, p < 0.01). When the disease progressed, concentrations of these criteria increased or decreased further (p < 0.01, p < 0.05). Significant correlations were found between a few lipid criteria for their mean concentrations in diseased groups. CONCLUSION The study demonstrates a correlation between abnormalities of lipid metabolism and the degrees of kidney insufficiency, and a correlation within certain kinds of lipid criteria in patients with different degrees of renal damage. The results suggest the existence of multi-correlations in vivo in catabolism and metabolism of lipid, lipoprotein, apolipoprotein, and protein in the patients. The exact mechanism responsible for the association and correlation remains to be clarified.

Abstract
OBJECTIVE To observe the effect of tonifying Kidney herbs (TKH) in pituitary, ovary, adrenal gland of androgen sterilized rats(ASR). METHODS ASR model was established by injecting testosterone propionate subcutaneously to SD female rats of 9 days age. Morphological and hormonal change of pituitary, ovary and adrenal gland in rats of 100-107 days old before and after feeding TKH extract were observed by light and electron microscope, cell culture immunohistochemical studies and radioimmuno-assay. RESULTS In the ASR groups, there were intracytopiasmic lipid drops, autophagy, vacuole, granulolysis of pituitary gland. There were anovulation apparently and increased the amount of lipid drops in cytoplasm of interstitial glandular cell of ovary. The fatty drops of the reticular zone of adrenal gland decreased, the numbers of AGNOR (P < 0.01) and PCNA (P < 0.01) increased significantly. The levels of FSH, LH (P < 0.05-0.005) lowered, but the levels of DHA, T (P < 0.01, 0.05, 0.001) were raised significantly. Morphological and hormonal change of all RSA returned to normal range after the treatment. CONCLUSIONS The hyperandrogenemia were disturbed by the function of sex gland axis and adrenal in female rats of 9 days old and played an important role in pathogenesis of ASR, the TKH reduced the levels of androgen and induced ovulation through sex gland axis and adrenal level and multi-organ regulation.

Abstract
OBJECTIVE To estimate the stability and reliability of lipoprotein(a) cholesterol measurement, and explore the possibility to evaluate lipoprotein(a) excess in plasma by using lipoprotein(a)-cholesterol assay alternatively to assay lipoprotein(a). SETTING Number 255 Hospital of PLA, Tangshan, Hebei, China. PRACTICE DESCRIPTION A total of 396 plasma samples from 100 healthy people (control), 107 chronic renal failure patients, 114 coronary heart disease patients, and 75 cerebral infarction patients, respectively, were measured for lipoprotein(a) cholesterol and lipoprotein(a) mass; lipoprotein(a) cholesterol and lipoprotein(a) mass levels among control and diseased groups were compared; and lipoprotein(a) cholesterol levels and lipoprotein(a) mass values from the control group were subjected to linear regression analysis. MAIN OUTCOME MEASUREMENTS The affinity between oligosaccharide contained in lipoprotein(a) and lectin wheat germ agglutinin to isolate lipoprotein(a) from other lipoproteins; lipoprotein(a) cholesterol and lipoprotein(a) mass detected by total cholesterol kits and enzyme linked immunosorbent assay kits, respectively. RESULTS Both lipoprotein(a) cholesterol and lipoprotein(a) mass levels of the chronic renal failure, coronary heart disease, and cerebral infarction groups were significantly higher than those of the control (P < 0.05 or P < 0.01) whereas no difference was seen among the diseased groups at the 0.05 level. Regression analysis within the control group showed a very high correlation between lipoprotein(a) cholesterol and lipoprotein(a) (r = 0.9932). CONCLUSION The results suggest that lipoprotein(a) cholesterol assay may be used in the place of lipoprotein(a) measurement for evaluating lipoprotein(a) excess for chronic renal failure, coronary heart disease, and cerebral infarction patients. Further studies about the mechanism of this association between lipoprotein(a) cholesterol and lipoprotein(a) levels are needed.

Abstract
Saiko-ka-ryukotsu-borei-to (TJ-12) is a Japanese kampo medicine used clinically for the treatment of hypertension and atherosclerosis. We investigated the effects of TJ-12 on the contraction of rat thoracic aorta induced by norepinephrine, 5-hydroxytryptamine and high potassium. TJ-12 relaxed endothelium-denuded rings, which had been precontracted with 1 microM norepinephrine, in a dose-dependent manner with an IC50 of 50 micrograms/mL. However, in the presence of TJ-12, endothelium-intact rings initially showed enhanced norepinephrine-induced contraction, followed by relaxation. Interestingly, TJ-12 dose-dependently reversed nitric oxide (2 microM)-induced relaxation of norepinephrine-induced precontraction ofendothelium-denuded rings, with an IC50 of 20 micrograms/mL. In serotonin-contracted rings, TJ-12 caused slight, though statistically significant, relaxation only at high doses (> 200 micrograms/mL). In constrat to these receptor-mediated contractions, TJ-12 failed to affect the tension produced by high potassium 40 mM). These results suggest that the antihypertensive effects of TJ-12 could be related to inhibition of norepinephrine-induced vasoconstriction. In addition, our in vitro experiments revealed an inhibitory effect on nitric oxide-induced relaxation.

Abstract
Young rats of 9-day old with testosterone propionate subcutaneously injected were used as an androgen sterilized rats (ASR) model. On 80th day, herbal extract of tonifying the Kidney was fed for 14 days, all animals were sacrificed by cardiac perfusion method on 100 days of ages. Morphological studies with light and electron microscope, immunohistochemical studies with argyrophilic nucleolar organiser region (AgNOR) and proliferating cell nucleolar antigen (PCNA) were used for observations on the morphological change of adrenal cortex. In control group (treated with testosterone propionate only) the reticular zone of the adrenal cortex extented widely in which cellular fatty drops, AgNOR and PCNA increased apparently. In animal treated with herbs, the width of the reticular zone, the numbers of AgNOR and PCNA reduced significantly to normal levels (P < 0.01, P < 0.01, P < 0.01) and numbers of fatty drops also decreased. It suggests that during inducing ovulation in ASR tonifying Kidney herbs simultaneously regulated the adrenal function besides the chief function on pituitary-ovary regulation.

Abstract
Histological and immunohistochemical features of 12 cases of malignant myoepithelioma of the salivary glands were studied.There were 4 major histologic types in the tumor tissues:(1)clear tumor cells proliferated mainly with or without keratin peral;(2)spindle shaped tumor cells proliferated mainly with or without mucoid regions;(3)plasmacytoid(hyaline) tumor cells were arranged in adenoid configurations.In the immunohistochemical studies,the tumor cells were positive for actin;myosin;glial,fibrillary,acidic,protein.(GFAP);S-100 protein antibodies.The authors consider that the application of the above-mentioned antibodies may assist in the differentiated diagnosis of malignant myoepithlioma.

Abstract
Injection of testosterone propionate 1.25 mg were given to SD rats on 9 days of age, and fed with replenishing Kidney herbal decoction as well as with distilled water as control from 80 to 94 days of age. On 100 days of age, all the rats were sacrificed and the pituitary glands and ovaries were excised for examination. In the ovaries, increase in interstitial glands' count and lowering of lipid drop's quantity in cytoplasm of interstitial glandular cells were observed after the treatment, and intracellular "crinophagy" and "autophagy" disappeared in the pituitary gland. After treatment with replenishing Kidney drugs, ovarian estrogen receptors increased whereas the ovarian progesterone receptors raised even higher. It suggests that both ovaries and pituitary gland in testosterone induced anovulatory rats were affected by herbs of replenishing Kidney.
