Nitrites play multiple characteristic functions in invasion and metastasis of hepatic cancer cells, but the exact mechanism is not yet known. Cancer cells can maintain the malignant characteristics via clearance of excess mitochondria by mitophagy. The purpose of this article was to determine the roles of nitrite, reactive oxygen species (ROS) and hypoxia inducing factor 1 alpha (HIF-1 α) in mitophagy of hepatic cancer cells. After exposure of human hepatocellular carcinoma SMMC-7721 cells to a serial concentrations of sodium nitrite for 24 h under normal oxygen, the maximal cell vitality was increased by 16 mg x (-1) sodium nitrite. In addition, the potentials of migration and invasion for SMMC-7721 cells were increased significantly at the same time. Furthermore, sodium nitrite exposure displayed an increase of stress fibers, lamellipodum and perinuclear mitochondrial distribution by cell staining with Actin-Tracker Green and Mito-Tracker Red, which was reversed by N-acetylcysteine (NAC, a reactive oxygen scavenger). DCFH-DA staining with fluorescent microscopy showed that the intracellular level of ROS concentration was increased by the sodium nitrite treatment. LC3 immunostaining and Western blot results showed that sodium nitrite enhanced cell autophagy flux. Under the transmission electron microscopy (TEM), more autolysosomes formed after sodium nitrite treatment and NAC could prevent autophagosome degradation. RT-PCR results indicated that the expression levels of COX I and COXIV mRNA were decreased significantly after sodium nitrite treatment. Meanwhile, laser scanning confocal microscopy showed that sodium nitrite significantly reduced mitochondrial mass detected by Mito-Tracker Green staining. The expression levels of HIF-1α, Beclin-1 and Bnip3 (mitophagy marker molecular) increased remarkably after sodium nitrite treatment, which were reversed by NAC. Our results demonstrated that sodium nitrite (16 mg x L(-1)) increased the potentials of invasion and migration of hepatic cancer SMMC-7721 cells through induction of ROS and HIF-1α mediated mitophagy.

Objective To investigate the therapeutic effect of intracerebral transplantation of mesenchymal stem cells(MSCs) derived from human umbilical cord blood(UCB) on hypoxic-ischemic brain damage(HIBD) in neonatal rat.Methods Twenty samples of human UCB were collected from healthy full-term newborns.MSCs were isolated from human UCB by density gradient centrifugation and purified by adhere cell selection method.For transplantation,P3 human UCB-derived MSCs were labeled by the 5-bromo-2-deoxyuridine (BrdU).Thirty SD rats of 7 d were built for neonatal HIBD model.One rat died and others were divided into transplant group(n=18) and control group(n=11).At the third day after building models,human UCB-derived MSCs were injected into left cortex in transplant group,while PBS of the same volume was injected into the same site in control group at the same time.The seventh day after transplantation,6 rats of transplant group were sacrificed to prepare brain tissue sections.The survival,migration and differentiation of the transplanted cells were investigated by brain tissue immunohistochemical analysis,and nervous function of 2 groups were evaluated by modified neurological severity score(mNSS) on the first,7th,14th,21th and 28th day after transplantation.Results MSCs were isolated from 5 of 20 human UCB samples.Immunocytochemical analysis of brain tissue showed that the transplanted human UCB-derived MSCs could survive and migrate around by the center of transplant site.There were (12.67?2.73)% of MSCs differentiated into astrocyte-like cells.mNSS showed that the score of transplant group was lower than that of control group on the first,7th,14th,21th and 28th day,and the differences of score points between 2 groups on the 14th,21th and 28thday were statistically significant(Pa

AIM:To observe related biological parameters of 3 minutes dark-room provocative test in patients with laser peripheral iridectomy(LPI) in the fellow eyes of acute primary angle-closure (APAC) by ultrasound biomicroscopy (UBM).To explore the risk factors in primary angle closure suspect(PACS) patients with progressive angle closure after LPI.METHODS: Seventy-eight eyes of APAC patients without peripheral anterior synechia were selected.Each eye underwent 3 minutes dark-room provocative test after LPI.Anterior segment parameters, including anterior chamber depth (ACD), anterior chamber angle open distance500 (AOD500), peripheral iris thickness (PIT), iris convex (IC), the position of iris insertion and trabecular-ciliary process distance (TCPD), and the number of positional angle closure(NPAC) were observed and analyzed by statistic methods.RESULTS:Patients with APAC were examined by UBM after LPI and 26 eyes(33%) occurs at least one positional angle closure,19 eyes(24%)were positive in 3 minutes dark-room provocative test among them.It occurs a positive relationship between the elevation intraocular pressure and the number of positional angle closure in dark-room provocative test(r=0.84, P<0.01).AOD500, IT and IC were significantly changed from normal light to darkroom between positional angle closure positive group and positional angle closure negative group(all P<0.01).In single factor analysis, AOD500(P=0.003), IT(P=0.012), IC(P=0.043), TPCD(P=0.015), the position of iris insertion(P=0.024) were correlative factors of positive results.In multiple-factor analysis, only IT(P=0.011), TPCD(P=0.009), iris root attachment points(P=0.02) were independent risk factors of positive results.CONCLUSION:A certain proportion of patients with PACS after LPI appeared positional angle closure in a dark room.Peripheral iris hypertrophy, anterior displacement of the ciliary body and iris root attachment points are vital risk factors.Long-term follow-up study and intervention treatment are required in these patients after LPI.

The clinical efficacy of acupuncture and moxibustion for post-stroke constipation was systematically reviewed. By computerized and manual retrieval of clinical research literature regarding acupuncture and moxibustion for post-stroke constipation, the randomized control trials (RCTs) that met the inclusive criteria were collected. Cochrane systematic review method was used and Revmen 5.2 software was adopted to perform this Meta analysis. Totally 8 articles were included, involving 610 cases of post-stroke constipation. As a result, the total effective rate and cured rate of acupuncture and moxibustion for post-stroke constipation were significantly superior to those of the control group [total effective rate: OR = 2.10, 95% CI (1.25, 3.54), Z = 2.78, P = 0.005; cured rate: OR = 2.37, 95% CI (1.57, 3.58), Z = 4.10, P < 0.0001]. This result indicated that acupuncture was effective for post-stroke constipation and had some advantages compared with other therapies. But the quality of included RCTs was low, and high-quality, large-sample and multi-center RCTs were needed to perform further verification.

METHODSAllergic rhinitis of lung deficiency and invasion of cold, spleen qi deficiency and kidney yang deficiency, 56 patients for each pattern/syndrome were randomized into a plaster therapy group and a nasal spray group, 28 cases in each one. In the plaster therapy group, according to the pattern/syndrome differentiation, with literature retrieval method, 3 acupoints of high frequency utility in clinic were selected as one group in acupoint plaster therapy. For lung deficiency and invasion of cold pattern/syndrome, Feishu (BL 13), Fengmen (BL 12) and Hegu (LI 4) were selected. For spleen qi deficiency pattern/syndrome, Pishu (BL 21), Zusanli (ST 36) and Dazhui (GV 14) were selected. For kidney yang deficiency pattern/ syndrome, Shenshu (BL 23), Dingchuan (EX-B 1) and Bailao (EX-HN 15) were selected. Separately, on July 13, 2013, July 23, 2013, August 2, 2013 and August 12, 2013, the aucpoint plaster therapy was applied, 2 to 4 h (1 to 2 h for children) each time. In the nasal spray group, beclometasone dipropionate aqueous nasal spray, 2 presses one nostril each time, 2 to 3 times a day, continuously for 4 weeks. The symptom score and efficacy were compared before and after treatment in the patients of the two groups.

RESULTSThe symptom scores of 3 patterns/syndromes were all apparently improved after treatment as compared with those before treatment in the patients of the two groups (all P<0.05), and the result in the plaster therapy group was better than that of the nasal spray group (P<0.05, P<0.01). For lung deficiency and invasion of cold pattern/syndrome, the total effective rate was 87.3% (20/24) in the plaster therapy group, better than 84.6% (22/26) in the nasal spray group (P<0.05). For spleen qi deficiency pattern/syndrome, the total effective rate was 83.3% (20/24) in the plaster therapy group, obviously better than 76.9% (22/26) in the nasal spray group (P<0.05). For kidney yang deficiency pattern/syndrome, the total effective rate was 79.2% (19/24) in the plaster therapy group, better than 76.9% (22/26) in the nasal spray group (P<0.05).

Objective To find out the iodine nutritional status and thyroid function of pregnant and lactating women in the urban areas of Wuwei City of Gansu Province,and to provide a scientific basis for iodine supplementation.Methods Blood and urine samples of pregnant (52 persons) and lactating women (59 persons) were collected in 2009.Urinary iodine content was measured with arsenic cerium catalytic spectrophotometric.Serum free three triiodothyronine(FT3),free thyroid hormone(FT4),triiodo thyronine(TT3),serum total thyroxine (TT4) and thyroid-stimulating hormone (TSH) were detected with direct chemiluminescence immunoassay.Results The medians urinary iodine of pregnant and lactating women were 274.68,217.88 μg/L.The rates of low urinary iodine (pregnant women below 150 μg/L,lactating women lower than 100 μg/L) were 9.62％ (5/52) and 6.78％ (4/59).Serum TT3,TT4 levels in pregnant women[(2.48 ± 0.59),(132.18 ± 33.36)nmoL/L] were higher than that in the lactating women[(2.16 ± 0.49),(108.79 ± 28.36)nmol/L,t =-3.123,-3.971,all P ＜ 0.05].Thyroid dysfunction incidence rates of pregnant and lactating women were 17.31％ (9/52) and 8.47％ (5/59).Thyroid dysfunction was mostly subclinical hypothyroidism.Conclusions Overall iodine nutrition of pregnant and lactating women is in good condition,some individuals have the trend of hypothyroidism.It is necessary to carry out routine monitoring of urinary iodine and thyroid function.

Objective Color doppler ultrasonography of chronic Keshan disease (CKD) was evaluated to provide evidences for clinic diagnosis of the disease. Methods From September to Novermber 2009, according to "Diagnostic criteria of Keshan disease" (GB 17021-1997), 64 cases of CKD were randomly sampled from five Keshan diseased districts in Shandong province, Zoucheng, Sishui, Yishui, Wulian, Jvxian, and Pingyi as patient group. Thirty four healthy volunteers being checked up by Shandong Institute for Endemic Diseases Control and Research were put in control group. All the subjects were examined with Color doppler ultrasonography. The indexes of cardiac structure, left ventricular (LV) systolic function and LV diastolic function were measured.Results Left atrial internal diameter, LV end-diastolic internal diameter, LV end-systolic internal diameter, right ventricular diameter, aorta diameter, right atrial transverse diameter, right atrial long diameter and left ventricle mass of the patient group[(35.38 ± 6.89), (61.57 ± 8.61), (45.39 ± 10.29), (17.22 ± 3.79), (28.69 ± 2.81),(38.00 ± 6.05), (42.68 ± 8.65)mm, (283.22 ± 103.12)g] were higher than that of control group[(26.70 ± 3.27),(45.41 ± 4.93), (26.91 ± 4.35), (13.76 ± 2.27), (24.09 ± 2.89), (31.50 ± 3.32), (35.82 ± 3.14) mm, (156.03 ±39.86)g, t = 6.93, 10.09, 9.98, 4.87, 7.64, 5.81, 4.46, 6.90, all P＜ 0.05]. The LV ejection fraction and fractional shortening of the left ventricular of the patient group[(49.25 ± 14.33)%, (26.11 ± 9.17)%] were lower than that of control group[(73.88 ± 4.04)%, (42.88 ± 3.62)%, t = - 9.79, - 10.22, all P＜ 0.05]. Diffuse hypokinetic motion of the left ventricle reduced in 95% (61/64) of CKD patients, and 5% (3/64) of CKD patients had segmental LV dyskinesia. Seventy five per sent(48/64) of the patients accompanied with mitral regurgitation, and 39% (26/64) of these cases accompanied with tricuspid regurgitation. Meaningful Mitral or tricuspid regurgitation was not found out in control group. Conclusions The CKD patients' bore of atrio-ventricular cavity and LV mass are enlarged, and their motion of ventricle is reduced or partly reduced. They have poor heart function. Mitral regurgitation are more than tricuspid regurgitation. Color doppler Ultrasonography is important in diagnosis of chronic Keshan discase.
