Objective To investigate the technical feasibility and oncological safety of EPMR for early esophageal cancer and precancerous lesions. Methods Clinicopathological data, procedure quality and complications of 70 patients with early esophageal cancer or precancerous lesions were retrospectively ana?lysed. The technical safety and feasibility were assessed, and the complications were investigated through postoperative surveillance. The results were compared with published data from two high?quality meta?analysis studies on ESD. Results In a total of 70 patients who underwent EPMR, 35?7%( 25/70) were diagnosed as having early esophageal cancer and 64?3%( 45/70) atypical hyperplasia. And tumor size greater than 2 cm was 78?6%(55/70). The mean EPMR time was(28?31±9?49) minutes. The R0 resection rate of EPMR was 88?6%(62/70) and no perforation occurred. The bleeding rate was 21?4%(15/70). The esoph?ageal stricture rate was 1?4%( 1/70) . The recurrence rate was 2?9%( 2/70) . Compared with published ESD data from the two studies, EPMR showed shorter procedure time, lower curative rate and lower rates of stric?ture and perforation, but slightly higher rates of bleeding and recurrence. Conclusion Both EPMR and ESD are feasible and effective for early esophageal cancer and precancerous lesions. The curative results of EPMR are similar to ESD, with shorter procedure time, but higher bleeding and recurrence rates.

Bone marrow mesenchymal stem cells (MSC) are the non-hematopoietic cellular component in the bone marrow that have multiple differentiation potency. MSC play a key role in the regulation of bone marrow hematopoietic niche and modulation of immune function through various mechanisms. They are currently recognized as a promising cell source in tissue engineering, a vehicle in gene therapy and a powerful tool in the management of graft-versus-host disease after allogeneic stem cell transplantation. In this review some momentous aspects regarding the current status and potential clinical applications of MSC in hematopoietic stem cell transplantation, aplastic anemia and multiple myeloma were summarized.

Objective To investigate the relationship between fatty liver progress and metabolic changes.Methods A total of 414 patients who had B-mode ultrasonography confirmed fatty liver development during 2 health check-ups within 2 years were enrolled in this study.Paired t and χ2 tests were used to compare body mass index (BMI),alanine aminotransferase (ALT),aspartate aminotransferase (AST),fasting plasma glucose (FPG),serum uric acid (UA),triglycerides (TG),and high-density lipoprotein cholesterol (HDL-C) among the participants.Results BMI,TG,HDL-C,ALT,AST,and UA were significantly increased after fatty liver progressed,although HDL-C was largely decreased.ConclusionsPrevention and treatment of MS as well as early intervention for fatty liver should be important for successful control of fatty liver.

The effects of magnolol (Mag) on hyperglycemia and hyperlipemia, hepatic oxidative stress and cytochrome P4502E1 (CYP2E1) activity of diabetic rats induced by high-fat diet (HFD) and streptozotocin (STZ) were studied. After oral administration of Mag (25, 50 and 100 mg x kg(-1) x d(-1)) for continuous 10 weeks, the blood glucose and lipids (TC, TG and LDL-C) levels, as well as the hepatic CYP2E1 activity and MDA content of diabetic rats, decreased significantly (P < 0.05 or P < 0.01), whereas the oral glucose tolerance and hepatic antioxidant enzymatic activities (CAT and GSH-Px) of diabetic rats, increased significantly (P < 0.05 or P < 0.01). The results indicated that Mag was effective against the hepatic oxidative damage, hyperglycemia and hyperlipemia of diabetic rats induced by HFD and STZ, and the inhibition of Mag on hepatic CYP2E1 activity could be an important mechanism of Mag against hepatic insulin resistance and oxidative damage.

OBJECTIVETo observe the clinical effect of Shen-reinforcing and menstrual cycle-regulating therapy (SRMCRT) combined with Western medicine (WM) in treating decline in ovarian reserve (DOR).

METHODSTotally 78 patients with DOR were assigned to the traditional Chinese medicine combined WM group (abbreviated as IM group, 40 cases), and the WM group (38 cases) according to random digit table method. Patients in the WM group were treated with hormone replacement therapy, while those in the IM group additionally received SRMCRT. The therapeutic course for all was 3 consecutive months. The therapeutic efficacy was compared between the two groups. The serum levels of follicle stimulating hormone (FSH), FSH/luteinizing hormone (LH), and estradiol (E2), as well as the development of sinus follicles were compared between before and after treatment in the two groups.

RESULTSThe therapeutic effective rate was 92.5% in the IM group, higher than that of the WM group (73.68%, P < 0.05). The serum levels of FSH, FSH/LH, and E2 decreased (P < 0.05) and the number of the sinus follicle increased (P < 0.05) in the two groups after treatment. Besides, IM was superior in decreasing serum levels of FSH and FSH/LH, and increasing the number of the sinus follicle (P < 0.05).

CONCLUSIONSSRMCRT was an effective method for treating ROD. IM was superior in decreasing serum levels of FSH and FSH/LH, and increasing the number of the sinus follicle.

Object To investigate the effect of PPARαactivation on PPARγ-induced fatty liver in the mouse. Methods Wild type mice ( C57BL/6) aged 4 to 5 weeks were used as animal models.All mice were divided into four groups.The mice in the first group were fed with chow diet.The mice in the second group were fed with a diet containing 0.125%Wy-14,643, an agonist of PPARa, for 8 days.The mice in the third group were injected with Ad/PPARγvia tail vein for 5 day.The mice in the fourth group were firstly fed with Wy-14,643 diet for 3 days and then injected with Ad/PPARγvia tail vein for another 5 day.Mouse livers were collected and photographed.The effect of PPARαactivation on PPARγ-induced fatty liver was observed by H&E and Oil red O staining.Results Compared with the controls, wild-type mice treated with Wy-14,643 for 8 days exhibited marked hypertrophy of hepatocytes with increased cytoplasmic eosinophil-ia and proliferation of peroxisomes.The liver size was significantly increased in the wild-type mice treated with Ad/PPARγfor 5 days, and over-expression of PPARγstrongly induced hepatic steatosis.Importantly, the wild-type mice pretreated with Wy-14,643 for 3 days and then given Ad/PPARγinjection exhibited dramatically the increase of liver size, which might be due to the dual function of PPARa and PPARγ.Compared with the Ad/PPARγgroup, the Wy-14,643 pretreat-ment group showed a reduced hepatic steatosis.Conclusions Activation of PPARαby Wy-14,643 effectively improves PPARγ-stimulated hepatic steatosis, which provides a novel target for prevention and therapy of fatty liver.

Objective To investigate the relationship between isolated systolic high-normal blood pressure and cor-onary heart disease (CHD) in the middle-aged and elderly population. Methods A total of 236 patients over 50 years old and undergone coronary angiography were enrolled and divided into isolated systolic high-normal blood pressure (ISHNBP) group (n=135) and non-ISHNBP (NISHNBP) group (n=101) according to their systolic and diastolic blood pressure levels. All clinical data and angiographic data were collected. Results There was no significant difference in systolic blood pres-sure between NISHNBP group and ISHNBP group (P>0.05). There were significantly lower levels of diastolic blood pres-sure and higher pulse pressure in ISHNBP group (P＜0.01). Results of multivariate logistic analysis showed that isolated sys-tolic high-normal blood pressure was the independent risk factor for CHD (OR=2.67,95%CI:1.50-4.75, P＜0.01). And the distribution of diseased coronary vessel numbers was more extensive in the ISHNBP group (P＜0.01). Conclusion The iso-lated systolic blood pressure in the middle-aged and elderly population with high risk of coronary heart disease should be paid attention to, and make appropriate interventions, which may help reduce the incidence of cardiovascular disease.
